Description

Technical Field

[0001] This utility model relates to the technical field of electric vehicles, and in particular to a taillight fixing structure. Background Technology

[0002] Traditional taillights are typically assembled using separate plastic components. They are installed separately from the frame and secured primarily with screws, clips, or adhesive. While this traditional design is simple and easy to implement, it suffers from poor taillight stability and a lack of integrated appearance, affecting the taillight's lifespan and safety. Improvements are needed. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing taillights that are separately mounted on the tube frame using plastic parts and screws, which affects the stability of the taillights and the overall aesthetics. It provides a new taillight fixing structure.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] A taillight fixing structure includes a tube frame and a taillight. The tube frame includes a left tube and a right tube. The taillight includes a diffuser. Both ends of the taillight are inserted into the left tube and the right tube respectively and welded to fix them. Both ends of the taillight are attached to the ends of the left tube and the right tube respectively. The diffuser protrudes from the upper surface of the tube frame.

[0006] The taillights are embedded in the tube frame at both ends and fixed by welding, which makes the taillights directly fixed to the tube frame, improving the integration, aesthetics and stability of the taillights and tube frame after assembly. At the same time, the diffuser makes the taillights emit more uniform light, improving the overall visual effect of the taillights.

[0007] Preferably, in the taillight fixing structure described above, the taillight further includes a reinforcing sheet metal part, and the reinforcing sheet metal part has a first welding plate on its left and right sides. The first welding plate is inserted into the left tube and the right tube respectively and welded to the bottom inner wall of the left tube and the right tube.

[0008] The reinforced sheet metal parts enhance the overall structural strength of the taillight. At the same time, the left and right sides of the reinforced sheet metal parts are welded and fixed to the left and right tubes respectively through the first welding plate, realizing the support and fixation of the taillight to the tube frame in the left rear direction and at the bottom. There is no need to expose other fixing structures to the outside of the tube frame, thus providing rigid support for the taillight and improving the firmness and aesthetics of the taillight fixed to the tube frame.

[0009] Preferably, in the taillight fixing structure described above, the left and right sides of the reinforcing sheet metal part have second welding plates protruding from the lower surface of the reinforcing sheet metal part, and the outer side wall of the second welding plate abuts against and is welded to the side ends of the left and right tubes.

[0010] The second welding plate allows for pre-positioning of the reinforcing sheet metal parts inserted into the pipe rack, while also increasing the welding area between the reinforcing sheet metal parts and the pipe rack, further improving the stability of the welding between the reinforcing sheet metal parts and the pipe rack.

[0011] Preferably, in the taillight fixing structure described above, the taillight further includes a light strip fixing seat and a rubber bushing. The diffuser is disposed at the upper end of the light strip fixing seat and protrudes from the outer surface of the left and right tubes. The rubber bushing has a placement cavity, and the light strip fixing seat is placed in the placement cavity for insertion and engagement. The inner wall of the rubber bushing is in contact with the outer surface of the light strip fixing seat, and the outer wall of the rubber bushing abuts against the ends of the left and right tubes, respectively.

[0012] The rubber bushing serves two purposes: firstly, it separates the light strip mounting bracket from the tube frame, acting as a buffer and seal to prevent the light strip installed in the mounting bracket from being damaged by vibration and to prevent dust from entering the mounting bracket, thus protecting the light strip mounting bracket and diffuser. Secondly, the rubber bushing eliminates assembly errors between the taillight assembly and the tube frame, increasing the tightness of the connection between the taillight assembly and the tube frame, and further improving the stability of the taillight assembly with the tube frame.

[0013] Preferably, in the taillight fixing structure described above, the rubber bushing has arc-shaped plates on opposite sides that are respectively inserted into the left and right tubes. The arc-shaped plates extend away from the rubber bushing, and the outer surface of the arc-shaped plates abuts against the upper inner wall of the tube frame.

[0014] The curved plate increases the contact area between the taillight and the upper part of the tube frame, enabling the taillight to support the inner wall of the upper part of the tube frame, and further improving the stability of the taillight fixed on the tube frame.

[0015] Preferably, in the taillight fixing structure described above, the taillight further includes a bottom shell, the rubber bushing and the reinforcing sheet metal parts are distributed between the light strip fixing seat and the bottom shell, the bottom shell and the light strip fixing seat are connected by screws and pressed against the bottom of the reinforcing sheet metal parts, the outer surface of the bottom shell is flush with the outer surface of the tube frame, and the left and right sides of the bottom shell are provided with limiting notches, and the second welding plate is inserted into the limiting notches for insertion and mating.

[0016] The bottom shell provides cover and protection for the reinforced sheet metal parts and the light strip mounting bracket and rubber bushing above them, while also further improving the integration and aesthetics of the taillights mounted on the tube frame.

[0017] Preferably, in the taillight fixing structure described above, the upper end of the bottom shell has limiting protrusions on both sides, and the lower surface of the light strip fixing seat has a limiting groove corresponding to the limiting protrusions, and the limiting protrusions are inserted into the limiting grooves for mating.

[0018] The limiting protrusion and the limiting groove are used to limit and fix the light strip holder and the bottom shell, which prevents the bottom shell from rotating when it is fixed to the light strip holder with screws. Attached Figure Description

The diffuser 21 is disposed at the upper end of the light strip fixing seat 23 and protrudes from the outer surface of the left tube 11 and the right tube 12. The rubber bushing 24 has a placement cavity 241. The light strip fixing seat 23 is placed in the placement cavity 241 for insertion and engagement. The inner wall of the rubber bushing 24 is in contact with the outer surface of the light strip fixing seat 23, and the outer wall of the rubber bushing 24 abuts against the ends of the left tube 11 and the right tube 12, respectively.

[0030] Preferably, the rubber bushing 24 has arc-shaped plates 242 on its opposite sides, which are respectively inserted into the left tube 11 and the right tube 12. The arc-shaped plates 242 extend away from the rubber bushing 24, and the outer surface of the arc-shaped plates 242 abuts against the upper inner wall of the tube frame 1.

[0031] Preferably, the taillight 2 also includes a base shell 25, with the rubber bushing 24 and the reinforcing sheet metal part 22 distributed between the light strip fixing seat 23 and the base shell 25. The base shell 25 and the light strip fixing seat 23 are connected by screws and pressed against the bottom of the reinforcing sheet metal part 22. The outer surface of the base shell 25 is flush with the outer surface of the tube frame 1. Limiting notches 251 are provided on the left and right sides of the base shell 25.
