[0033] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.
[0034] Reference should be made to Figures 1 to 6 In a preferred embodiment, the thin backlight module mainly comprises a backlight assembly 1, a frame 2, an upper shell 3 and a lower shell 4. The frame 2 is sleeved on the outer periphery of the backlight assembly 1, and the upper shell 3 and the lower shell 4 are respectively sleeved on the frame 2 from the two sides in the height direction. The outer peripheral wall of the frame 2 is provided with at least one connecting plane 21, the connecting plane 21 is provided with a plurality of positioning bosses 22, the upper shell 3 comprises at least one first extension 31 and at least one first notch 32, the lower shell 4 comprises at least one second extension 41 and at least one second notch 42, the first extension 31 and the second extension 41 are respectively clamped with the corresponding positioning boss 22, and the first extension 31 extends to the corresponding second notch 42, and the second extension 41 extends to the corresponding first notch 32.
[0035] For example, the backlight assembly 1 can be a backlight module of an existing display device, for example, the backlight assembly 1 can comprise a display screen, a light guide plate, a light source and a plurality of optical film materials. The frame 2 can be a rectangular frame made of metal or plastic, which is sleeved on the outer periphery of the backlight assembly 1 for fixing the backlight assembly 1. The upper shell 3 and the lower shell 4 are respectively sleeved on the frame 2 from the upper and lower sides, wherein the upper shell 3 has an opening for exposing the display screen, and the lower end face of the lower shell 4 is formed as a closed plate.
[0036] The connecting plane 21 of the frame 2 is provided with a positioning boss 22, and the upper shell 3 and the lower shell 4 can be respectively clamped with the positioning boss 22 through the first extension part 31 and the second extension part 41, so as to realize the connection of the upper shell 3 and the lower shell 4 with the frame 2, which is simple in structure and convenient for assembly and disassembly. The upper shell 3 is provided with a first notch 32 corresponding to the second extension part 41, and the lower shell 4 is provided with a second notch 42 corresponding to the first extension part 31. When the upper shell 3 and the lower shell 4 are connected with the frame 2, the first notch 32 and the second notch 42 respectively form an avoidance for the second extension part 41 and the first extension part 31, so that the first extension part 31 and the second extension part 41 can still maintain sufficient area to ensure that they can be stably connected with the positioning boss 22 under the premise of reducing the thickness of the backlight module, thereby meeting the demand for thinning of the backlight module.
[0037] Please refer to Figures 3 to 6 The positioning boss 22 includes a first boss 221 and a second boss 222, the first extension part 31 is provided with a first clamping hole 33 for clamping with the first boss 221, and the second extension part 41 is provided with a second clamping hole 43 for clamping with the second boss 222. For example, the size of the first clamping hole 33 matches the size of the first boss 221, and the size of the second clamping hole 43 matches the size of the second boss 222. In this embodiment, the first clamping hole 33 is formed as a through hole penetrating the first extension part 31 in the thickness direction, and the second clamping hole 43 is formed as a through hole penetrating the second extension part 41 in the thickness direction. In other possible embodiments, the first clamping hole 33 and the second clamping hole 43 can be grooves respectively arranged on the inner surfaces of the first extension part 31 and the second extension part 41. The first extension part 31 is clamped with the first boss 221 through the first clamping hole 33, and the second extension part 41 is clamped with the second boss 222 through the second clamping hole 43, which is simple in structure, easy to process, and can ensure the stable connection of the upper shell 3 and the lower shell 4 with the frame 2.
[0038] The first boss 221 and the second boss 222 are both provided with a guide slope 223, and the direction of the guide slope 223 of the first boss 221 is opposite to the direction of the guide slope 223 of the second boss 222. By arranging the guide slope 223 on the first boss 221 and the second boss 222, the first extension part 31 and the second extension part 41 can more easily slide through the first boss 221 and the second boss 222 during assembly, thereby realizing clamping and making the assembly more convenient.
[0039] When the first extension part 31 and the second extension part 41 are connected with the positioning boss 22, the first extension part 31 and the second extension part 41 are arranged at intervals along the length direction of the connecting plane 21. The arrangement of the first extension part 31 and the second extension part 41 at intervals along the length direction of the connecting plane 21 can ensure the stable connection of the upper shell 3 and the lower shell 4 with the frame 2 and improve the stability of the overall structure.
[0040] In the embodiment, the first extension part 31 is two, and the two first extension parts 31 are respectively close to two ends of the length direction of the connecting plane 21. By arranging the first extension part 31 to be two and respectively close to two ends of the length direction of the connecting plane 21, the connection between the upper shell 3 and the frame body 2 can be stable. Correspondingly, the second extension part 41 is one, and the second extension part 41 is clamped with the at least two positioning bosses 22. By arranging the second extension part 41 to be one, the structure is simpler and easier to process, and the second extension part 41 is clamped with the at least two positioning bosses 22 at the same time, so that the lower shell 4 can be stably fixed by the single second extension part 41.
[0041] The connecting plane 21 is at least two, and the at least two connecting planes 21 are located on a pair of opposite sides of the outer circumferential wall of the frame body 2. By arranging the connecting plane 21 on a pair of opposite sides of the outer circumferential wall, the stress on both sides of the upper shell 3 and the lower shell 4 can be uniform, so that the overall structure is more stable and reasonable. It can be understood that in other possible embodiments, the connecting plane 21 can be four, that is, the four outer circumferential planes of the frame body 2 are all arranged with the connecting plane 21. This structure can simplify the connection structure of the upper shell 3, the lower shell 4 and the frame body 2, and at the same time ensure the stability of the connection.
[0042] The height of the positioning boss 22 extending out of the connecting plane 21 is less than or equal to the thickness of the first extension part 31 and the second extension part 41. When the first extension part 31 and the second extension part 41 are clamped with the positioning boss 22, it can be ensured that the positioning boss 22 is located on the inner side of the clamping opening, so that the positioning boss 22 extending out of the clamping opening does not increase the width of the module.
[0043] In the embodiment, the corners of the frame body 2, the upper shell 3 and the lower shell 4 are all formed as round corners. By forming the corners of the frame body 2, the upper shell 3 and the lower shell 4 as round corners, the collision between the components during assembly can be avoided, and the assembly yield and quality of the product can be ensured.
