Collision between the gaps would cause damage to the lamp body, leading to customer complaints. In addition, the relative movement of the lower trim panel and the rear door lamp body under assembly would cause abnormal noises. When the car audio is turned on, the entire rear door lamp would also produce slight abnormal noises, affecting the audio quality, with unclear levels and a sense of noise, affecting the life and rest of the user and his or her family, and could also cause hearing loss in the user, causing adverse reactions such as tinnitus, which would result in driving safety and have an adverse effect on safe driving.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-5 The technical solution provided by the utility model is: a new type of anti-abnormal noise structure, including a lower decorative panel 1 and a lamp body 2, a plurality of claws 3 are arranged on one side of the lower decorative panel 1, and a plurality of blocks 4 adapted to the claws 3 are arranged on one side of the lamp body 2. The claws 3 are clamped on the blocks 4, and the lower decorative panel 1 is assembled on the lamp body 2. The blocks 4 are provided with convex points 41, and the convex points 41 are located at the upper part of the blocks 4. The thickness of the blocks 4 gradually increases from the top to the convex points 41. The thickness of the lower part of the convex points 41 on the blocks 4 is less than the thickness at the convex points 41. The claws 3 are limited by the convex points 41 on the blocks 4, so that the claws 3 are firmly clamped on the blocks 4. No abnormal noise will occur between the lower decorative panel 1 and the lamp body 2 during driving of the car, and the lamp body will not be damaged by shaking, thereby avoiding the occurrence of car failures and making driving safer.

[0016] Specifically, a convex-shaped hollow 31 is provided in the middle of the claw 3, and the clamping block 4 is clamped in the middle part of the hollow 31. The gap in the middle part of the hollow 31 is larger than the gap on both sides. When clamping, the claw 3 moves upward, and after being clamped to the clamping block 3 on the lamp body 2, the claw 3 moves downward again, and the convex point 41 is clamped on the inner side of the claw 3, and the clamping block 4 is clamped in the middle part of the hollow 31 on the claw 3, fitting without gap, and the buckle is firm.

[0017] Specifically, the width of the middle part of the hollow 31 is a, a is 3.1 mm, and the width of the clamping block 4 is b, b is 1.22 mm, so that the clamping claw 3 can be smoothly clamped on the clamping block 4, making the assembly convenient and tool-free.

[0018] Specifically, the number of the clamping claws 3 and the clamping blocks 4 is two, and the two clamping claws 2 are located on both sides of the lower decorative plate 1 .

[0019] The installation process of the utility model is as follows: first, the lamp body 2 is welded and fixed with the light distribution mirror, and then the claw 3 on the lower decorative plate 1 moves upward so that the claw 3 is clamped on the clamp block 4, and the lower part of the clamp block 4 is located in the middle part of the hollow 31 on the claw 3, and then the claw 3 moves downward so that the convex point on the clamp block 4 is clamped inside the claw 3, and at this time, the upper part of the clamp block 4 is clamped tightly in the middle part of the hollow 31 on the claw 3, and the fit is seamless and the buckle is firm. Compared with the original limit rib structure, the utility model is buckled and fastened, will not shake and produce abnormal noise, will not damage the lamp body 2, is easy to assemble, and does not require tools.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
