[0002] At present, vehicle taillights are one of the important safety devices on vehicles. Their design and functions are aimed at improving the visibility and driving safety of vehicles. Vehicle taillights are usually installed at the rear of the vehicle. As the main rear identification light of the vehicle, the taillights can enable vehicles and pedestrians traveling behind to identify the location and existence of the vehicle at night or in bad weather conditions, thereby avoiding collisions and accidents. In short, vehicle taillights play a vital role in improving vehicle visibility and driving safety. By clearly and clearly displaying the vehicle's position, direction of travel and parking intention, taillights help reduce the potential risk of collision with other road users, ensure riding safety and improve the driving experience.

[0003] However, at present, some vehicle taillights are set to switch back and forth between different illumination angles, illumination intensities, and light colors for dynamic adjustment. While increasing the degree of conspicuousness, it also combines beauty and personality. However, this type of taillight has a disadvantage. The taillight needs to be equipped with a device for switching the illumination angle and different lamp beads and light boards, which makes the taillight overall heavier and does not meet the requirements of lightweight.

[0023] See attached Figures 1 to 3 : A lens mounting groove 2a for mounting lenses of different specifications is provided on the outside of the cylindrical lampshade 2, and a lamp bead mounting groove 3a for mounting lamp beads of different specifications is provided on the outside of the lamp post 3. The lens mounting groove 2a corresponds to the lamp bead mounting groove 3a. Lenses with different refraction angles or light expansion sizes can be installed in the lens mounting groove 2a, and lamp beads with different lighting intensities or luminous colors can be installed in the lamp bead mounting groove 3a. Different illumination effects can be switched by rotating the lamp post 3 and the cylindrical lampshade 2.

[0024] See attached Figures 1 to 3: A spiral groove 7 is provided on the outside of the main shaft 4, and a guide block 8 is fixedly installed on the through hole 6, which is inserted into the spiral groove 7 and can slide along the spiral groove 7. When the main shaft 4 slides axially, it rotates through the spiral groove 7 and the guide block 8. A push block 9 is fixedly installed at one end of the main shaft 4, which pushes the main shaft 4 to slide axially by inertia, and a limit plate 10 is fixedly installed at the other end of the main shaft 4. During the driving process of the car, the inertia generated by acceleration, braking, bumps, body vibrations and other behaviors drives the push block 9 to reciprocate. During the reciprocating motion, the push block 9 drives the main shaft 4 to reciprocate in the axial direction. When the main shaft 4 reciprocates in the axial direction, it drives the main shaft 4 to rotate through the guide block 8 and the spiral groove 7. The rotation of the main shaft 4 and the reciprocating motion in the axial direction will drive the lamp post 3 to rotate and reciprocate in the axial direction. During the driving process of the car, the inertia generated by acceleration, braking, bumps, body vibrations and other behaviors will also drive the cylindrical lamp cover 2 to rotate.

A positioning rod 13 capable of clamping the cylindrical lampshade 2 is detachably connected to the lampshade positioning hole 11 through a thread, and the positioning rod 13 passes through the lamp post positioning hole 12. After passing through the lamp post positioning hole 12, the positioning rod 13 is threadedly connected to the lampshade positioning hole 11 to clamp the cylindrical lampshade 2. At this time, the positioning rod 13 can limit the rotation of the cylindrical lampshade 2 and the rotation and sliding of the main shaft 4, so that the lighting effect is fixed, and the lighting no longer has dynamic changes. The user can switch whether to need a dynamic lighting effect according to needs.

[0026] See attached Figures 1 to 3 A counterweight block 14 is arranged on the outside of the cylindrical lampshade 2 for driving the cylindrical lampshade 2 to rotate. The function of the counterweight block 14 is to utilize the inertia of the vehicle during driving to drive the cylindrical lampshade 2 to rotate better.
