AI Technical Summary
The existing motorcycle taillights have insufficient brightness control in the light guide section, resulting in poor warning effect, especially in strong light environments, and slow response speed, which affects driving safety; uneven light guide effect leads to low clarity of warning signals.
The light guide installation unit, including a light guide section, thick wall, positioning section, limiting section and locking section, is adopted. It achieves quick and stable installation through threaded fasteners, ensuring accurate positioning and stable fixation of the light guide section and the lamp cover.
It enables rapid and stable installation of the light guide unit under various working conditions, ensuring the normal and stable operation of the light guiding and warning functions, improving the warning effect and signal clarity in strong light environments, and reducing the risk of traffic accidents.

A vehicle taillight with a Y-shaped light guide structure, comprising a lamp cover (1) and a lamp body (2), characterized in that: The vehicle taillights also include a light guide mounting unit (3); The light guide mounting unit (3) includes a light guide part (31), a thick wall (32), a positioning part (33), a limiting part (34), and a locking part (35); The light guide (31) is located on the side of the lampshade (1), and the light guide (31) has a Y-shaped structure; The thick wall (32) is disposed on the side of the light guide (31), and the thick wall (32) is located on the side of the light guide (31); A Y-shaped opening (11) is provided on the side of the lampshade (1) for the corresponding positions of the thick wall (32) and the light guide (31). The positioning part (33) has multiple parts, which are respectively arranged on the side of the lamp cover (1), and the end face of the thick wall (32) is provided with a through hole for the positioning part (33) to pass through. When the thick wall (32) moves, it can slide through the positioning part (33) and abut against the Y-shaped opening (11) on the end face of the lamp cover (1). The limiting part (34) has multiple parts and is slidably disposed on the side of the positioning part (33); The locking part (35) has multiple parts and is rotatably disposed on the outside of the limiting part (34), and the multiple locking parts (35) can all be in contact with the outside of the light guide part (31).
2. The vehicle tail light having a Y-shaped light guide structure according to claim 1, characterized in that: Multiple limiting parts (34) are all L-shaped structures, and a circular hole is provided in the middle of the limiting part (34) for the locking part (35) to be inserted. When the limiting part (34) is rotated, the bottom end face of the L-shaped structure of the limiting part (34) can be in contact with the outer side of the light guide part (31).
3. The vehicle tail light having a Y-shaped light guide structure according to claim 2, characterized in that: The locking part (35) is a threaded fastener. In the working state, when the locking part (35) rotates, it can bring the end face of the limiting part (34) into contact with the end face of the positioning part (33).
4. The vehicle tail light having a Y-shaped light guide structure according to claim 3, characterized in that: In the installed state, the light guide (31) corresponds to the Y-shaped opening (11) on the side of the lampshade (1), and the end face of the light guide (31) is in contact with the inner end face of the thick wall (32).
5. The vehicle tail light having a Y-shaped light guide structure according to claim 4, characterized in that: The light guide mounting unit (3) also includes a protrusion (36); there are multiple protrusions (36), which are respectively disposed on the top of the limiting part (34), and the protrusions (36) are located on the L-shaped structure of the limiting part (34); in the installed state, the protrusions (36) can be in contact with the outer side of the light guide part (31).
6. A vehicle taillight with a Y-shaped light guide structure according to claim 5, characterized in that: The multiple protrusions (36) are all triangular structures. In the installed state, the multiple triangular structures are used to support the end face of the light guide (31).
7. The vehicle tail light having a Y-shaped light guide structure according to claim 6, characterized in that: Multiple limiting parts (34) can rotate around the locking part (35) as the rotation center.
