DETAILED DESCRIPTION



[0019] The present disclosure will be described in detail below in conjunction with the embodiments shown in the drawings. However, the embodiments do not limit the disclosure, and the changes on structure, method or function made by those skilled in the art according to the embodiments are all included in the protection scope of the present disclosure.

[0020] The terms used in the present disclosure are for the purpose of describing particular embodiments only, and are not intended to limit the disclosure. The singular forms "a" and "the" as used in the present disclosure and the appended claims intend to include the plural forms thereof, unless the context clearly indicates other meanings. It should further be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0021] As shown in FIG. 1, FIG. 1 is an exploded perspective view of a ceiling lamp structure shown according to an exemplary embodiment. The ceiling lamp structure 100 of the present disclosure breaks the conventional installation mode, does not need to be deliberately docked during installation, can be assembled by pushing up at any angle, and can be disassembled conveniently, so that ordinary users can quickly install it by themselves, which is quick and convenient, and greatly reduces the difficulty of installing the ceiling lamp structure 100.

[0022] The ceiling lamp structure 100 of the present disclosure includes: a lamp top tray 11; a lamp body 12 mounted to the lamp top tray 11; and an elastic latch module 13 disposed on the lamp body 12. When the ceiling lamp structure 100 is assembled, the lamp top tray 11 is fixed to a predetermined position in the house by screws, expansion screws, or the like in advance, and then the lamp body 12 is assembled to the lamp top tray 11, such that the assembly of the ceiling lamp structure 100 is completed. The respective components of the lamp body 12 can be pre-assembled the assembly with the lamp top tray 11 in advance. The present disclosure utilizes the elastic latch module 13 to realize that the lamp body 12 can be quick assembled with the lamp top tray 11.

[0023] As shown in FIG. 5 to FIG. 8, the lamp top tray 11 further includes: a hook portion 111, disposed on the circumferential side wall of the lamp top tray, and configured to mate with the elastic latch module 13. When the lamp body 12 is being assembled with the lamp top tray 11, the elastic latch module 13 is compressed by an external force to make the lamp body 12 and the lamp top tray 11 be docked. After the lamp body 12 and the lamp top tray 11 are assembled in place, the external force on the elastic latch module 13 disappears, and the elastic latch module 13 is restored under the elastic force, to mate with the hook portion 111 to fix the connection. Specifically, when the lamp body 12 and the lamp top tray 11 are assembled, the circumferential side wall of the lamp top tray 11 acts on the elastic latch module 13 to apply force on the elastic latch module 13, so as to compress the lamp body 12 to be assembled with the lamp top tray 11. After the elastic latch module 13 fully inserts into the hook portion 111, the external force acting on the elastic latch module 13 disappears. At this time, the elastic latch module 13 returns to the initial state under the elastic restoring force, then directly mates with the hook portion 111 to fix the latch, that is, to realize that the lamp body 12 can be assembled with the lamp top tray 11.

[0024] In a preferred embodiment of the present disclosure, the lamp body 12 is provided with two elastic latch modules 13 disposed on two sides of the lamp body 12 that are in a central symmetry. The two elastic latch modules 13 can realize the effect of the balance of the assembly between the lamp body 12 and the lamp top tray 11, and at the same time, the lamp body 12 can be directly pushed up to be assembled with the lamp top tray 11 without any other auxiliary assembly action, so that the fixing effect is good and the operation is simple. For a larger or heavier lamp body 12, more elastic latch modules 13 can be adopted to ensure the reliability of assembly between the lamp body 12 and the lamp top tray 11. Of course, in another embodiment of the present disclosure, it can adopt only one elastic latch module 13, the side of the lamp body 12 opposite to the elastic latch module 13 can be provided with a hook, a sticking sheet, etc., to be connected with the lamp top tray 11 in advance, and then the elastic latch module 13 is adopted to realize a fixed connection.

[0025] As shown in FIG. 1 and FIG. 5, the lamp body 12 includes: a lamp housing 121; a lamp panel 122 located in the lamp housing 121; and a lamp cover 123 mounted to the lamp panel 122 or the lamp housing 121. The lamp housing 121 is fixed to the lamp panel 122. The lamp cover 123 can be fixed to the lamp panel 122 or fixed to the lamp housing 121 according to different designs. Preferably, the circumferential side surface of the lamp cover 123 is coincident with the circumferential side surface of the lamp housing 121, so as to prevent dust from falling into the lamp cover 123, thus the dust can be effectively prevented. The dustproof level may be IP50, so as to prevent harmful dust accumulation, to create a relatively closed using environment, thus to extend the life of the lamp.

[0026] The lamp body 12 further includes a light source (not shown) disposed on the lamp panel 122. The light source and the elastic latch module 13 are disposed on two sides of the lamp panel 122. The light cover 123 and the light source are located on the same side of the lamp panel 122. The light cover 123 is disposed on the light source to protect the light source and aid diffusion of the light source. The lamp cover 123 is disposed on a side of the lamp panel 122 that is opposite to the lamp top tray 11, and the elastic latch module 13 is disposed on a side of the lamp panel 122 that faces the lamp top tray 11. The lamp panel 122 is provided with a guide slot 124 for accommodating the elastic latch module 13. The elastic latch module 13 is subjected to an external force, and it can slide in the guide slot 124.

[0027] The elastic latch module 13 of the present disclosure includes: a pressing member 131; a latching member 132 fixed to the pressing member 131; an elastic member 133 connected to the pressing member 131 and the lamp panel 122 respectively; and a latch-fixing cover 134 covering above the guide slot 124. The pressing member 131 and the latching member 132 are restricted to slide in the guide slot 124. In an embodiment of the present disclosure, a slide slot (not shown) is disposed in the guide slot 124, and both sides of the pressing member 131 are restricted in the slide slot, so that the pressing member 131 is restricted to move in one direction. In still another embodiment of the present disclosure, the pressing member is provided with a slot hole, the longitudinal direction of the slot hole is consistent with a radial direction of the lamp body, a limit column is disposed in the guide slot. The pressing member mates on the limit column, so as to move along the slot hole.

[0028] Further, the pressing member 131 includes: a pressing body 1311; and a pressing portion 1312 provided at the end portion of the pressing body 1311. In the embodiment of the present disclosure, the pressing portion 1312 is located at the head end of the pressing body 1311, and the elastic member 133 is connected to the tail end of the pressing body 1311. Optionally, the elastic member 133 is a spring, and the axial direction of the spring is the same as the direction of motion of pressing member 131. The latching member 132 is located on the pressing body 1311. The pressing body 1311 has a larger size in the sliding direction than that of the latching member 132, and the pressing portion 1312 is away from the center of the lamp body 12 relative to the latching member 132. After the lamp body 12 is mounted on the lamp top tray 11, the pressing portion 1312 is located outside the lamp top tray 11, and the latching member 132 is located in the lamp top tray 11.

[0029] In an embodiment of the present disclosure, the external side of the latching member 132 includes a reversed spine configured to mate with the hook portion 111. The inverted spine includes: a guide slope 1321; and a positioning portion 1322 that mates with the hook portion 111 for fixing. When the lamp body 12 is mounting on the lamp top tray 11, the lamp top tray 11 acts on the guide slope 1321, at this time, the latching member 132 brings the pressing member 131 to compress inward, and the elastic member 133 is in a compressed state. The lamp top tray 11 may continue relatively sliding along the guide slope 1321 until it moves to the positioning portion 1322. Since the positioning portion 1322 is recessed relative to the guide slope 1321, the lamp top tray 11 no longer acts on the hook portion 111, at this time the elastic member 133 is restored to the initial state under its own property, then the inverted spine moves outward as well, that is, it can mate with the hook portion 111.

[0030] As shown in FIG. 1 to FIG. 3, in an embodiment of the present disclosure, the hook portion 111 is formed by inwardly turning the end of the side wall of the lamp top tray 11 that is close the lamp body 12, that is, the hook portion 111 is of a barbed shape on the circumferential side wall of the lamp top tray 11. When the lamp top tray 11 acts on the reversed spine, the hook portion 111 abuts against the guide slope 1321 of the reversed spine and slides along the guide slope 1321 until the hook portion 111 and the positioning portion 1322 are mated.

[0031] As shown in FIG. 1, FIG. 2 and FIG. 4, in another embodiment of the present disclosure, the hook portion 111 is a slot hole formed in the circumferential side wall of the lamp top tray 11. As needed for assembly, a plurality of slot holes may be provided in the circumferential side wall of the lamp top tray 11, such that, when the lamp body 12 and the lamp top tray 11 is being assembled, no specific assembly position is needed. When the lamp top tray 11 acts on the reversed spine, the circumferential side wall of the lamp top tray 11 abuts against the guide slope 1321 of the reversed spine and slides along the guide slope 1321 until the reversed spine inserts the slot, then the mating between the hook portion 111 and the reversed spine is completed.

[0032] Further, the ceiling lamp structure 100 further includes: a connector assembly 14 disposed between the lamp top tray 11 and the lamp body 12. The connector assembly 14 includes: a first connector 141 disposed in the lamp top tray 11, and a second connector 142 disposed in the lamp body 12. The connector assembly 14 of the present disclosure can complete the electrical connection by docking the first connector 141 and the second connector 142 together. Such fitting is simple and requires no other operation, so it is suitable for the manner in which the lamp body 12 and the lamp top tray 11 of the present disclosure are assembled.

[0033] In an embodiment of the present disclosure, the first connector 141 is a coupler module, and the second connector 142 is a circular coupler guide slot. The coupler module includes a circular connection portion configured to mate with the circular coupler guide slot. Elastic flake contacts (not shown) are provided in both the circular connection portion and the circular coupler guide slot to mate with each other for electrical connection, by which, when the first connector 141 and the second connector 142 are docked to each other, the electrical connection is completed.
