DETAILED DESCRIPTION



[0027] In order to make objects, technical solutions and advantages of the present application apparent, the technical solutions of the embodiment will be described in a clearly and fully understandable way in connection with the embodiments of the present application and the drawings related to the embodiments of the present application. It is obvious that the described embodiments are just a part but not all of the embodiments of the present application. Based on the described embodiments herein, those skilled in the art can obtain other embodiment(s), without any inventive work, which should be within the protection scope of the present application.

Embodiment 1



[0028] As shown in FIG. 3 and FIG. 4, the embodiment discloses a linear lamp. The linear lamp includes a housing 20 and a splicing member 10, where the number of the housing 20 is at least two.

[0029] Each of the splicing member 10 includes a main body 11, a first side body 12, and a second side body 13, wherein the first side body 12 and the second side body 13 are connected to and distributed on two opposite sides of the main body 11 respectively. A first snap-fit part 121 is provided in the first side body 12. A second snap-fit part 131 is provided in the second side body 13. The splicing member 10 has specific elasticity. For example, the splicing member 10 may be a metal sheet. The main body 11, the first side body 12, and the second side body 13 may be integrally formed, or the main body 11, the first side body 12, and the second side body 13 may be welded and connected together.

[0030] The first snap-fit part 121 of the first splicing member 10 and the second snap-fit part 131 of the second splicing member 10 are in snap-fit connection. The second snap-fit part 131 of the first splicing member 10 and the first snap-fit part 121 of the second splicing member 10 are in snap-fit connection. That is, the first snap-fit part 121 of one splicing member 10 and the second snap-fit part 131 of the adjacent splicing member 10 are in snap-fit connection. Therefore, the adjacent splicing members 10 are spliced together. After the splicing member 10 is mounted at an end of the housing 20, the adjacent splicing members 10 are spliced together, so that the two adjacent housings 20 are spliced together.

[0031] In the embodiment, the splicing member 10 is simple in structure and convenient to be spliced. The two splicing members 10 are opposite in placement direction and are connected to the adjacent housings 20 respectively, and then the two splicing members 10 are spliced, so that the two adjacent housings 20 can be rapidly spliced together. In the embodiment, when the housings 20 are connected, the splicing members 10 with a same structure are used, so that design cost can be reduced.

[0032] As shown in FIG. 7, the splicing members 10 are mounted at two ends of each housing 20 respectively. As shown in FIG. 10 to FIG. 12, the housing 20 has two or more ends, and the splicing member 10 is mounted at each end. As shown in FIG. 24, an end cover 70 is provided on an outer end of the housing 20 located on a tail portion of the linear lamp, and the splicing member 10 is mounted at an inner end. The housings 20 with different structures and the housings 20 in different positions are provided with different numbers of splicing members 10, which can be arranged according to actual needs.

[0033] As shown in FIG. 15, the housing 20 includes a bottom plate 24 and two side plates 25, wherein the bottom plate 24 and the two side plates 25 are connected and enclose a first mounting space 21. After the two adjacent housings 20 are spliced together, facing end faces are attached together, and the splicing members 10 are entirely located in the first mounting space 21. In the embodiment, due to the structure of the splicing members 10, the splicing members 10 can still be spliced together after being detached from the housing 20. Referring to FIG. 4 and FIG. 7, the first side body 12 of one splicing member 10 is limited in an outward direction by an inner side wall of one side plate 25 of the housing 20, and the first side body 12 of the adjacent splicing member 10 is limited in an outward direction by an inner side wall of the other side plate 25 of the housing 20. Because the splicing members 10 have specific elasticity, the second side body 13 is located on an inner side of the first side body 12 and can exert outward extrusion force on the first side body 12. The side plate 25 has the function that when the second side body 13 outward extrudes the first side body 12, the side plate 25 can prevent the first side body 12 from moving outward, so that the second side body 13 is closely attached to the first side body 12, and the first snap-fit part 121 and the second snap-fit part 131 can be more reliably in snap-fit connection.

[0034] In the embodiment, the splicing members 10 have specific elasticity, so that the first snap-fit part 121 and the second snap-fit part 131 can more easily achieve snap-fit connection. In addition, the limiting effect of the side plate 25 prevents the first side body 12 from moving outward due to elasticity.

[0035] As shown in FIG. 1 and FIG. 2, the first side body 12, the second side body 13, and the main body 11 enclose an accommodating space 14. As shown in FIG. 7 and FIG. 9, the splicing member 10 is inserted into the first mounting space 21, and the main body 11 is fixed to the bottom plate of the housing 20 by using a screw, so that the splicing member 10 is fixed in the housing 20, and the accommodating space 14 communicates with the first mounting space 21. The main body 11 is attached to the bottom plate 24 of the housing 20, and the first side body 12 and the second side body 13 are parallel to and closer to the two side plates 25 respectively, so that the splicing member 10 in the embodiment not only can rapidly connect the two adjacent housings 20, but also has the advantages of being small in occupied space and capable of accommodating other parts, for example, the accommodating space 14 may accommodate the photoelectric module 40.

[0036] As shown in FIG. 9, two strip-shaped ribs 22 spaced from each other are provided on the inner side wall of the side plate 25, the strip-shaped ribs 22 extend in a length direction of the housing 20, a slot 23 is formed between the two strip-shaped ribs 22, and a length direction of the slot 23 is consistent with the length direction of the housing 20. The splicing member 10 further includes a first connection body 15, one end of the first connection body 15 is connected to the main body 11, and the other end of the first connection body 15 is bent away from the second side body 13 toward the slot 23 and is connected to the first side body 12. The splicing member 10 further includes a second connection body 16, one end of the second connection body 16 is connected to the main body 11, and the other end of the second connection body 16 is bent away from the first side body 12 toward another slot 23 and is connected to the second side body 13. When the splicing member 10 is inserted into the first mounting space 21 from a port of the housing 20, in the presence of a bent part of the first connection body 15, the first side body 12 can be inserted into the slot 23. In the presence of a bent part of the second connection body 16, the second side body 13 can be closer to the slot 23, or the second side body 13 is also inserted into the slot 23. In this case, as shown in FIG. 6, the first side body 12 is limited in an outward direction by a slot bottom of the slot 23. The slot 23 can also limit the first side body 12 in an up and down direction and prevent the first side body 12 from dislocation, so that the first snap-fit part 121 and the second snap-fit part 131 are easily in snap-fit connection. The up and down direction herein is consistent with a width direction of the slot 23.

[0037] In the embodiment, the first side body 12 and the second side body 13 of the linear lamp both extend in the length direction of the housing 20, the length of the first side body 12 is larger, and the second side body 13 may be disposed directly facing the middle of the first side body 12. As shown in FIG. 1, a left end of the first side body 12 and a right end of the second side body 13 are different-side ends, or a right end of the first side body 12 and a left end of the second side body 13 are different-side ends. The first snap-fit part 121 and the second snap-fit part 131 are distributed at the different-side ends of the first side body 12 and the second side body 13, so that the two splicing members 10 can have more overlapped parts when being spliced, and space can be saved.

[0038] A through-hole 122 is provided on the first side body 12, the first snap-fit part 121 is disposed adjacent to the through-hole 122, and an edge of the first snap-fit part 121 forms a side wall of the through-hole 122. The first snap-fit part 121 is formed by partially recessing the first side body 12 toward the second side body 13, which is beneficial to reduce the number of components and parts. The first snap-fit part 121 protrudes out of an inner side surface of the first side body 12. The inner side surface of the first side body 12 is a surface facing toward the second side body 13.

[0039] As shown in FIG. 8, the through-hole 122 can accommodate a portion of the second snap-fit part 131, so that a contact area of the first snap-fit part 121 and the second snap-fit part 131 is relatively larger, which further improves reliability of the snap-fit connection of the first snap-fit part 121 and the second snap-fit part 131. A guide slope 1211 is provided on a surface of the first snap-fit part 121 facing toward the second side body 13, and the guide slope 1211 is used to improve splicing smoothness of the two splicing members 10.

[0040] The second snap-fit part 131 is formed by partially recessing the second side body 13 away from the first side body 12, which is beneficial to reduce the number of components and parts. The second snap-fit part 131 protrudes out of an outer side surface of the second side body 13. The outer side surface of the second side body 13 is a surface facing away from the first side body 12. The second snap-fit part 131 extends from an end face of the second side body 13 to the other end of the second side body 13, a groove 1311 is provided on the second snap-fit part 131, and the groove 1311 extends from an end face of the second side body 13 to the other end of the second side body 13. A second guide part 132 bent toward the first side body 12 is provided at the other end of the second side body 13, thereby improving splicing smoothness of the two splicing members 10.

[0041] As shown in FIG. 4, surfaces of the snap-fit connection of the first snap-fit part 121 and the second snap-fit part 131 are a first snap-fit surface 1212 and a second snap-fit surface 1312 respectively, and the first snap-fit surface 1212 and the second snap-fit surface 1312 face each other and are in snap-fit connection. In the presence of the groove 1311, during detachment, a tool is easily inserted into the groove 1311 and pries the first snap-fit part 121 and the second snap-fit part 131 so as to separate the first snap-fit part 121 and the second snap-fit part 131.

[0042] A protruding height of the second snap-fit part 131 is less than a depth of the through-hole 122, that is, the depth of the through-hole 122 is larger, so that the second snap-fit part 131 cannot extend out of an outer surface of the first side body 12, the first side body 12 is attached to the slot bottom of the slot 23, occupied space is saved, and it can be ensured that the slot bottom of the slot 23 can limit the first side body 12. The outer surface of the first side body 12 is a surface of the first side body 12 facing away from the second side body 13. The slot bottom of the slot 23 is a side wall of the housing 20 located in the slot 23.

[0043] Because the first side body 12 has specific elasticity and a larger length, and a reinforcing rib 125 is provided on the first side body 12 and are used to increase insertion reliability of the first side body 12 and the slot 23. The reinforcing rib 125 may extend in the length direction of the first side body 12.

[0044] FIG. 5 and FIG. 6 show two straight-line shape housings 20. As shown in FIG. 10 to FIG. 12, the housing 20 includes a transition module 29, and the transition module 29 is used at a turn. The transition module 29 includes at least two extension parts 291, and the at least two extension parts 291 are perpendicular to each other.
