Description

Technical Field

[0001] The present disclosure relates to the technical field of lighting equipment, and in particular to a ceiling lamp.

Background Art

[0002] A ceiling lamp is a kind of lighting equipment. As the name suggests, it is called a ceiling lamp because the bottom of the lighting equipment is completely attached to the ceiling when mounted. Of course, in the absence of a suspended ceiling, some ceiling lamps can also be directly mounted on the top wall. Ceiling lamps are commonly used lighting equipment in various places such as homes, offices, and entertainment venues.

[0003] Traditional ceiling lamps require opening the front cover or rear cover of the structural shell to adjust the internal modules first, in which terminals are connected to power lines or signal lines, and then the ceiling mounting of the lamp body is completed. Due to the large weight of the lamp body, these operations are not convenient, leading to issues such as difficulties in high-altitude operations, low efficiency, and poor customer experience.

Summary

[0004] One object of the present disclosure is to provide a ceiling lamp, which realizes the objective of quick mounting for the ceiling lamp and rapid electrical connection for the ceiling lamp.

[0005] In order to achieve the above objective, the technical solutions adopted in the present disclosure are as follows. A ceiling lamp comprises an electric appliance box module and a lamp body module, wherein the electric appliance box module is suitable for connection with the ceiling and is provided with a perforation exposed on an upper surface for the external wires through the perforation to connect with wire-connecting terminals inside the electric appliance box module; the lamp body module is thereon provided with a mounting groove suitable for accommodating the electric appliance box module, with an opening of the mounting groove facing upwards and exposed externally; the lamp body module is suitable to be detachably connected to the electric appliance box module through the mounting groove; and an outer periphery of the electric appliance box module is provided with a first conductive element electrically connected to the wire-connecting terminals, and the mounting groove is provided therein with a second conductive element suitable for electrical connection with the first conductive element, to enable an electrical connection between the electric appliance box module and the lamp body module.

[0006] The basic steps for mounting the ceiling lamp are as follows: (1) connecting the external wires through the perforation to the wire-connecting terminals inside the electric appliance box module; (2) mounting the electric appliance box module onto the ceiling; and (3) aligning the mounting groove with the electric appliance box module and moving the lamp body module, allowing the electric appliance box module to insert into the mounting groove of the lamp body module. Therefore, the quick mounting of the lamp body module is achieved. It is understood that, after inserting the electric appliance box module into the mounting groove, the first conductive element and the second conductive element naturally establish an electrical connection. By achieving the fast ceiling-mounting of the ceiling lamp, the ceiling lamp also accomplishes the function of rapid electrical connection.

[0007] Compared with the prior art, the beneficial effects of the present disclosure are described as follows. (1) The basic steps for mounting the ceiling lamp, as described above, enable fast mounting of the ceiling lamp and rapid electrical connection of the ceiling lamp. The duration of handholding the lamp body module during the mounting process is short, allowing for easy lifting manner using the palm without exerting much effort. Additionally, there is no need to worry about the lamp body module slipping from the hand. During the connection of the electric appliance box module and the lamp body module, the wires are already fixed inside the electric appliance box module, eliminating interference. The entire process is simple and convenient to operate, significantly reducing the operation difficulty of high-altitude mounting of the ceiling lamp, and thus improving mounting efficiency, especially the mounting efficiency for arranging ceiling lamps over large areas. Therefore, the product experience of the consumer is enhanced. (2) The basic operation steps for maintenance or removal of the ceiling lamp are exactly opposite to the mounting steps. First, the lamp body module is removed, and then the electric appliance box module is removed. This operation is also easy, allowing for quick maintenance or disassembly operation. (3) The mounting groove has an opening upwardly, and the perforation is arranged on the upper surface of the electric appliance box module. This is to allow the wires to extend from the ceiling and then pass directly through the perforation into the electric appliance box module from top to bottom, which can reduce the distance for wire layout and avoids wire winding or exposure around the ceiling lamp, where exposed wires lead to a safety hazard and an aesthetic distraction.

Detailed Description of Embodiments

[0019] Below, in conjunction with specific embodiments, further descriptions of the present disclosure will be provided. It should be noted that, unless conflicting, the various embodiments described below or the technical features can be arbitrarily combined to form new embodiments.

[0020] In the description of the present disclosure, it is to be understood that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on those shown in the drawings, and are intended only to facilitate the description of the present disclosure and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be construed as a limitation of the present disclosure.

[0021] It should be noted that the terms "first", "second", etc., used in the summary and claims of the present disclosure, are used to distinguish between similar objects and are not intended to describe a particular order or sequence.

[0022] The terms "comprise" and "have" and any variations thereof in the summary and claims of the present disclosure are intended to cover non-exclusive inclusion. For example, processes, methods, systems, products, or devices comprising a series of steps or units do not necessarily have to be limited to those steps or units explicitly listed but may include other steps or units that are not explicitly listed or are inherent to these processes, methods, products, or devices.

[0023] FIG. 1 is a schematic diagram of the mounting structure of a ceiling lamp in the prior art. It includes the lamp body 01, the power connection box 02, and the mounting buckle 03. The power connection box 02 includes a box body 021 and a cover body 022. The box body 021 and the lamp body 01 can be integrally arranged. They can also be detachably connected in a separate arrangement. The mounting steps are as follows. First, the mounting buckle 03 is fixed to the ceiling. Additionally, the lamp body 01 is held; and the wire is threaded through the perforation 022a on the cover body 022, connected to the wire-connecting terminals pre-set, and fixed inside the box body 021 of the power connection box 02 on the lamp body 01. Then the cover body 022 is fixed to the box body 021 with screws. Next, the decorative cover 04 is fixed to the side surface of the box body 021, and finally, the entire lamp body 01 with the connected wire is snapped onto the mounting buckle 03. This mounting method not only involves cumbersome operations but also presents several problems. For instance, throughout the entire mounting process of the ceiling lamp, hands are essentially holding the lamp body 01, thus requiring multi-handed operations to complete multiple mounting steps. This is highly inconvenient during high-altitude operations and can easily exhaust the installer. Additionally, for instance, to facilitate wiring and the mounting of the cover body 022, it is necessary to hold the lamp body 01 at an angle, with the box body 021 opening facing the installer. However, the lamp body 01 usually has a certain weight and volume, and its rounded shape and smooth surface make it challenging to grip. Simultaneously, the connected wire, disturbed along with the lamp body 01, obstructs the view of the installer and hinders operations of screw tightening. In summary, the existing mounting methods for the ceiling lamp are inconvenient to operate and slow to mount, which is poor in mounting efficiency.

[0024] In one embodiment, to solve the problems of inconvenient operation, slow mounting speed, and poor mounting efficiency of the existing mounting method for the ceiling lamp, the present disclosure provides a ceiling lamp. As shown in FIGS. 2 to 9, it includes an electric appliance box module 10 and a lamp body module 20. The electric appliance box module 10 is suitable for connection with the ceiling and is provided with a perforation 1a exposed on an upper surface for the external wires through the perforation 1a to connect with wire-connecting terminals inside the electric appliance box module 10. The lamp body module 20 is thereon provided with a mounting groove 2a suitable for accommodating the electric appliance box module 10, with an opening of the mounting groove 2a facing upwards and exposed externally. The lamp body module 20 is suitable to be detachably connected to the electric appliance box module 10 through the mounting groove 2a. Additionally, an outer periphery of the electric appliance box module 10 is provided with a first conductive element 111 electrically connected to the wire-connecting terminals, and the mounting groove 2a is provided therein with a second conductive element 21 suitable for electrical connection with the first conductive element 111, to enable an electrical connection between the electric appliance box module 10 and the lamp body module 20.

[0025] The basic steps for mounting the ceiling lamp as follows: (1) connecting the external wires through the perforation 1a to the wire-connecting terminals inside the electric appliance box module 10; (2) mounting the electric appliance box module 10 onto the ceiling; and (3) aligning the mounting groove 2a with the electric appliance box module 10 and moving the lamp body module 20, allowing the electric appliance box module 10 to insert into the mounting groove 2a of the lamp body module 20. Therefore, the quick mounting of the lamp body module 20 is achieved. It is understood that, after inserting the electric appliance box module 10 into the mounting groove 2a, the first conductive element 111 and the second conductive element 21 naturally establish an electrical connection. By achieving the fast ceiling-mounting of the ceiling lamp, the ceiling lamp also accomplishes the function of rapid electrical connection.

[0026] Compared with the prior art, the beneficial effects of the present disclosure are described as follows. Compared with the prior art, the beneficial effects of the present disclosure are described as follows. (1) The basic steps for mounting the ceiling lamp, as described above, enable fast mounting of the ceiling lamp and rapid electrical connection of the ceiling lamp. The duration of handholding the lamp body module 20 during the mounting process is short, allowing for easy lifting manner using the palm without exerting much effort. Additionally, there is no need to worry about the lamp body module 20 slipping from the hand. During the connection of the electric appliance box module 10 and the lamp body module 20, the wires are already fixed inside the electric appliance box module 10, eliminating interference. The entire process is simple and convenient to operate, significantly reducing the difficulty of high-altitude mounting of the ceiling lamp, and thus improving mounting efficiency, especially the mounting efficiency for arranging ceiling lamps over large areas. Therefore, the product experience of the consumer is enhanced. (2) The basic operation steps for maintenance or removal of the ceiling lamp are exactly opposite to the mounting steps. First, the lamp body module is removed, and then the electric appliance box module 10 is removed. This operation is also easy, allowing for quick maintenance or disassembly operation. (3) The mounting groove 2a has an opening upwardly, and the perforation 1a is arranged on the upper surface of the electric appliance box module 10. This is to allow the wires to extend from the ceiling and then pass directly through the perforation 1a into the electric appliance box module 10 from top to bottom. It reduces the distance for wire layout and avoids wire winding or exposure around the ceiling lamp, where exposed wires lead to a safety hazard and an aesthetic distraction. Moreover, the electric appliance box module 10 is accommodated in the mounting groove 2a of the lamp body module 20, thus facilitating packaging and transportation for manufacturers and sellers. Additionally, after the ceiling lamp is mounted, the lamp body module 20 fits closely with the ceiling, resulting in minimal gaps, which helps reduce dust accumulation on the top. This also enhances the aesthetic appeal when viewing the ceiling lamp from the side.

[0027] As preferred, the electric appliance box module 10 comprises an electric appliance box base 11 and an electric appliance box back cover 12; the electric appliance box base 11 and the electric appliance box back cover 12 are arranged in a vertical direction, and the two can be detachably connected; the wire-connecting terminals are arranged inside the electric appliance box base 11, and the perforation 1a is arranged at a higher one of the electric appliance box base 11 and the electric appliance box back cover 12. Considering the potential for wires to bend and the fact that the wire-connecting terminals may not be directly aligned with the perforation 1a, inserting the wires from the outside of the perforation 1a into the wire-connecting terminals aligned on the other side of the perforation 1a is inconvenient. Therefore, the electric appliance box module 10 is arranged as a separate part to facilitate the connection of external wires to the wire-connecting terminals after passing through the perforation 1a. When connecting the electric appliance box module 10 to power, first the wires are threaded through the perforation 1a on the electric appliance box back cover 12 or the electric appliance box base 11. Then, the electric appliance box base 11 and the electric appliance box back cover 12 are closed to each other and fixedly connected together.

[0028] Specifically, in the embodiment, as shown in FIGS. 2 to 4, the electric appliance box back cover 12 is arranged beneath the electric appliance box base 11, and the perforation 1a is arranged on the top of the electric appliance box base 11. In other words, during mounting, the wire is threaded through the perforation 1a, and then the back cover is mounted beneath the electric appliance box base 11 to cover and protect the circuit modules and other components inside the electric appliance box base 11. Afterward, the electric appliance box base 11 is connected to the ceiling. Understandably, at the wire entry point, namely the perforation 1a, a waterproof connector should be employed to prevent water or dust from entering the electric appliance box module 10 and affecting the power supply and heat dissipation.

[0029] From the drawings, it can be seen that the electric appliance box module 10 is detachably connected to the ceiling via bolt assembly. This is the usual way of connecting to the ceiling, which is a reliable and stable connection at a low cost. The bolt assembly can specifically be an expansion bolt or a combination of a screw and an expansion tube, and, of course, can include washers and the like.

[0030] Furthermore, the electric appliance box base 11 includes a top plate 112, and the top plate 112 is arranged oppositely to the ceiling. The top plate 112 is provided with multiple bolt holes 112a around the top plate for connecting bolt assembly. In the embodiment, there are a total of four bolt holes 112a, and the specific shape of the bolt holes 112a can be waist-shaped or any other shape. It is easy to understand that when mounting the top plate 112 onto the ceiling, the bolt assembly is threaded from the bottom to the top. The head portion and the rod portion of the bolt assembly enter the ceiling, with the end portion remaining below the top plate 112. To prevent the end of the bolt assembly from protruding downward, the bottom surface of the top plate 112 is provided with a recessed region 112b, and the bolt hole 112a is arranged within the range of the recessed region 112b.

[0031] The electric appliance box base 11 further comprises a circular baffle 113 extending along a height direction based on the top plate 112, wherein the circular baffle 113 surrounds to form a mounting cavity 11a. The wire-connecting terminals are provided within the mounting cavity 11a. The top plate 112 comprises a mounting portion 1121 arranged on an outside of the circular baffle 113, and the recessed region 112b is arranged on the mounting portion 1121. In other words, the bolt hole 112a is arranged on the mounting portion 1121. The bolt hole 112a is provided avoiding the mounting cavity 11a to avoid occupying the internal space of the mounting cavity 11a, thus facilitating the machining and production of the bolt hole 112a, and making the mounting of bolt assembly more convenient.

[0032] Further, a part of the mounting portion 1121 shields above the first conductive element 111 so as to block and protect the first conductive element 111.

[0033] In the embodiment, the central portion of the top plate 112 forms a top portion of the mounting cavity 11a, and the electric appliance box back cover 12 is detachably connected, through the bolt assembly, to the baffle 113 to form a bottom portion of the mounting cavity 11a. More specifically, the electric appliance box back cover 12 is provided with mounting lugs 121 outwardly protruding, and the mounting lugs 121 are thereon provided with mounting holes 121a suitable for the passage of bolt assembly. The baffle 113 is provided with an inner recessed stepped surface 1131 that matches the electric appliance box back cover 12 so as to allow the electric appliance box back cover 12 to be accommodated within the circular baffle 113. The inner recessed stepped surface 1131 is provided with multiple hole positions corresponding one-to-one with the mounting holes 121a. The connection method between the electric appliance box back cover 12 and the electric appliance box base 11 is simple, making it easy to assemble and disassemble. Additionally, the electric appliance box back cover 12 can be accommodated within the circular baffle 113, thus preventing the electric appliance box back cover 12 from protruding outward.

[0034] Furthermore, a sealing gasket can be arranged between the electric appliance box back cover 12 and the inner recessed stepped surface 1131 to enhance the sealing performance.

[0035] As preferred, the electric appliance box module 10 and the lamp body module 20 are slidably connected. As shown in FIGS. 5 to 7, one end of the mounting groove 2a penetrates a side surface of the lamp body module 20. The mounting groove 2a, along its length direction, is provided with a slide rail 2aa, wherein the electric appliance box module 10 is provided with an insertion portion 1122 suitable to be inserted from a penetrating end of the mounting groove 2a into the slide rail 2aa. When the insertion portion 1122 slides along the slide rail 2aa to a stroke end, the first conductive element 111 and the second conductive element 21 contact with each other to establish an electrical connection. The sliding connection is easy to achieve, with a simple structure, and it facilitates easy operation during mounting or disassembly.

[0036] Specifically, the slide rail 2aa is designed as two rectangular grooves that are inner recessed and arranged on two opposite side walls of the mounting groove 2a, respectively. The insertion portion 1122 is provided with two elongated plate bodies protruding towards both sides, wherein the two insertion portions 1122 are inserted into the corresponding slide rails 2aa from both sides. In other words, on both sides of the electric appliance box module 10, an insertion portion is 1122 inserted into the slide rail 2aa, thus ensuring even force distribution on both sides and smoother sliding.

[0037] In the embodiment, the insertion portions 1122 are arranged on both sides of the top plate 112. The basic shape of the top plate 112 is rectangular, and the insertion portions 1122 are arranged on the two long sides of the top plate 112. The insertion portion 1122 has a certain thickness. It can specifically be in the range of 2mm to 4mm, for example, 2mm, 3mm, or 4mm, to ensure that the insertion portion 1122 has a certain structural strength, allowing for long-term use without deformation.

[0038] As an improvement, the insertion portion 1122 is provided with guiding portion 11221. This can be understood in conjunction with FIGS. 7 and 11. The guiding portion 11221 is suitable for guiding the insertion portion 1122 into the slide rail 2aa. Further, the guiding portion 11221 is a rounded corner.

[0039] In other embodiments, the guiding portion 11221 can obviously be designed in different shapes. For example, they can be inclined surfaces, with the distance between the two guiding portions 11221 slightly smaller than the distance between the opposite side surfaces of the two slide rails 2aa, thus enabling the insertion guiding function.

[0040] In other embodiments, the initial segment of the guide rail is outwardly expanded to facilitate guiding the insertion portion 1122 into the guide rail. In other words, the guide rails on both sides can have widened openings near one end of the lamp body module 20. When aligning and inserting the electric appliance box module 10 into the mounting groove 2a, it is only necessary to roughly align the insertion portion 1122 with the slide rail 2aa, thus reducing the difficulty of alignment and improving the efficiency of high-altitude operations.

[0041] The electric appliance box base 11 and the electric appliance box back cover 12 are each integrally molded so as to reduce processing and assembly steps, resulting in better structural strength for the electric appliance box module 10.

[0042] The mounting groove 2a is divided into two sections, wherein a first-section groove body 2a1 penetrating the side surface of the lamp body module 20 has a larger groove depth to facilitate the accommodation of the lower mounting cavity 11a. A second-section groove body 2a2, close to the inside, has a smaller groove depth to accommodate the top plate 112 of the corresponding electric appliance box base 11. Further, a width of the slide rail 2aa is greater than a thickness of the insertion portion 1122. Firstly, due to the difficulty in machining, demolding and maintaining the horizontal degree of the slide rails 2aa when arranging elongated strip-shaped slide rails 2aa within the mounting groove 2a, the slide 2aa with a larger width is easier to create. Secondly, setting the depth of the first-section groove body 2a1 and/or the second-section groove body 2a2 or arranging other limiting structures can enable that the bottom of the electric appliance box module 10 abuts against the bottom of the mounting groove 2a, and the insertion portion 1122 abuts against the top of the slide rail 2aa, allowing the entire electric appliance box module 10 to be fixed in the height direction. It is not necessary to solely rely on the insertion portion 1122 to be inserted into the slide rail 2aa to restrict the upward and downward movement of the electric appliance box module 10.

[0043] Additionally, a bottom surface of the mounting groove 2a is provided with a projecting portion 2a11 protruding upwardly so as to abut and press against a bottom of the electric appliance box module 10.

[0044] The projecting portion 2a11 includes a pair of protrusions arranged at intervals from each other, which is provided with a guiding slope 2a facing the penetrating end of the mounting groove so as to gradually jack up the electric appliance box module 10 during the insertion of the electric appliance box, thus limiting downward movement of the electric appliance box module 10.

[0045] As preferred, as shown in FIGS. 5 and 8, the first conductive element 111 and the second conductive element 21 are a combination of male and female plug pins. The combination of male and female plug pins has a low cost. The first conductive element 111 is arranged at the end of the electric appliance box base 11 along the insertion direction, and the second conductive element 21 is arranged at the corresponding end of the mounting groove 2a. When the electric appliance box module 10 is inserted into the mounting groove 2a, the first conductive element 111 and the second conductive element 21 are automatically connected in a manner of insertion. A part of the mounting portion 1121 shields above the first conductive element 111 so as to provide protection for the first conductive element 111. In the drawings, the mounting portion 1121 of the top plate 112 includes a portion that protrudes relative to its own insertion direction, and the portion is located within the second groove. In other words, a part of the mounting portion 1121 shields above the first conductive element 111. Understandably, the connection method of the male and female plug pins means that there is a certain gap between the circular baffle 113 and the inner end of the first groove. If the gap is communicated with the outside, it is easy to cause water seepage and dust accumulation at the male and female plug pins, thus affecting the electrical connection. In the embodiment, the mounting portion 1121 includes a portion suitable for insertion into the second groove, and the portion shields above the gap, thus avoiding exposure of the male and female plug pins to the air.

[0046] For the objective of protecting the male plug pin, the second conductive element 21 is designed as a male plug pin, so as to be shielded and protected within the mounting groove 2a.

[0047] Additionally, as shown in FIG. 11, the electric appliance box module 10 is provided with a notch 11b suitable for mounting the first conductive element 111. The notch 11b is inwardly recessed to allow at least a portion of the first conductive element 111 to be located inside the electric appliance box module 10. The first conductive element 111 can be fixed by methods such as snapping, welding, or screw fixation.

[0048] In other embodiments, the first conductive element 111 and the second conductive element 21 can be arranged elsewhere and can be of different shapes. For instance, they can be arranged on both sides of the electric appliance box module 10 in the form of a combination of probes and metal contact points. When the electric appliance box module 10 is inserted into the mounting groove 2a, the probes abut against the metal contact points, thus achieving electrical connection.

[0049] Additionally, to ensure the durability of the plug pins, elastic components such as elastic sheets or spring can be arranged at the first conductive element 111 and/or the second conductive element 21 for buffering. This helps prevent damage to the first conductive element 111 and the second conductive element 21 due to too rapid insertion or inserting with excessive force.

[0050] Further, the ceiling lamp further includes a decorative side plate 30. As shown in FIG. 3 and FIG. 9, the decorative side plate 30 comprises a decorative portion 31 filling a side wall of the lamp body; and a plug plate 32, extending from both sides of the decorative portion 31, wherein the plug plate 32 is suitable for insertion into the mounting groove 2a and suitable for insertion into the slide rail 2aa. An upper half of the plug plate 32 expands outward to support within the slide rails 2aa on both sides of the mounting groove 2a, and a lower half of the plug plate 32 abuts against a bottom of the mounting groove 2a. The decorative side plate 30 is provided to seal the penetrating end of the mounting groove 2a. Covering and protecting the electric appliance box module 10 within the mounting groove 2a enhances the aesthetics of the ceiling lamp and the sealing performance within the mounting groove 2a.

[0051] The lamp body module 20 comprises an integrally molded rear shell 22, and the mounting groove 2a is arranged on the rear shell 22, which has good structural strength and structural stability.

[0052] The detailed mounting process of the ceiling lamp is as follows. The wire passes from top to bottom through the perforation 1a on the electric appliance box base 11, connecting to the wire-connecting terminals inside the mounting cavity 11a. The bolt assembly fixes the electric appliance box back cover 12 to the electric appliance box base 11, integrating the electric appliance box module 10 as a whole. The electric appliance box module 10 is then fixed to the ceiling or wall top using the bolt assembly. The mounting groove 2a is aligned with the electric appliance box module 10. The lamp body module 20 is inserted by moving it laterally and inserting it in place, thus making the first conductive element 111 and the second conductive element 21 connected. The decorative side plate 30 is mounted. The entire mounting process is convenient for operation, especially in high-altitude work, as the components held in hand are relatively small.

[0053] In the second embodiment, the present disclosure provides another ceiling lamp, as shown in FIGS. 10 and 11. It also includes an electric appliance box module 10 and a lamp body module 20. The electric appliance box module 10 is suitable for connection with the ceiling and is provided with a perforation 1a exposed on an upper surface for the external wires through the perforation 1a to connect with wire-connecting terminals inside the electric appliance box module 10. The lamp body module 20 is thereon provided with a mounting groove 2a suitable for accommodating the electric appliance box module 10, with an opening of the mounting groove 2a facing upwards and exposed externally. The lamp body module 20 is suitable to be detachably connected to the electric appliance box module 10 through the mounting groove 2a. Additionally, an outer periphery of the electric appliance box module 10 is provided with a first conductive element 111 electrically connected to the wire-connecting terminals, and the mounting groove 2a is provided therein with a second conductive element 21 suitable for electrical connection with the first conductive element 111, to enable an electrical connection between the electric appliance box module 10 and the lamp body module 20.

[0054] It differs from the first embodiment in that the electric appliance box back cover 12 is provided above the electric appliance box base 11, and the perforation 1a is provided on the electric appliance box back cover 12. In other words, during installation, the wires are first connected to the wire-connecting terminals through the perforation 1a, then the electric appliance box base 11 is connected to the back cover, and then the electric appliance box module 10 is mounted to the ceiling. Further, in the embodiment, the middle portion of the top plate 112 is hollowed out to mount the electric appliance box back cover 12. The electric appliance box back cover 12 forms the top of the mounting cavity 11a, and the bottom of the mounting cavity 11a is provided with a base plate.

[0055] Other structures can be the same as in the first embodiment.
