Technical Field

[0001] The utility model relates to the technical field of vehicle lamp manufacturing, in particular to a vehicle lamp single-light lens device. Background Art

[0002] At present, the automotive single-light lens uses a single large-area lens to produce a complex beam shape to achieve the concentration and control of light. The single-light lens can better control the shape and direction of the light beam, provide higher light efficiency and more uniform lighting effects. This technology can make the lighting range of vehicle headlights wider and farther, while also reducing the scattering and glare of the light beam and improving driving safety. Because the single-light lens has a simple design and compact structure, it can also bring more flexibility and possibilities to car design. In general, the automotive single-light lens is an advanced automotive headlight design technology that can improve lighting effects, reduce glare, and also has better design flexibility and aesthetics.

[0003] The current problem with single-light lenses in cars is that the angle of light emitted by the single-light lens is too single. In bad weather or road conditions, the effect of light emitted by the single-light lens is poor. In this case, the light lacks dynamic changes and is not easily noticed by other vehicles and pedestrians, which can easily cause accidents. Utility Model Content

[0018] The following provides a preferred specific implementation of the present utility model in conjunction with the accompanying drawings. What is disclosed is only a better specific implementation of the present utility model, and it certainly cannot be used to limit the scope of rights of the present utility model. Therefore, equivalent changes made according to the claims of the present utility model are still within the scope covered by the present utility model.

[0019] Refer to the attached Figures 1 to 3: In this embodiment, the single-light lens device of the vehicle lamp includes a lamp post 1, which is cylindrical. One end of the lamp bead 1 is fixed on the vehicle body, and a lampshade 2 is mounted on the outside of the lamp post 1. The lampshade 2 is a cylinder that can rotate on the outside of the lamp post 1. A lens 3 is installed on the lampshade 2 and is used to refract the light of the lamp post 1. The lens 3 is composed of several pieces of lenses that refract the light to different angles. The lens 3 can also be composed of several pieces of lenses that gather or disperse the light. The rotation of the lampshade 2 causes the light of the lamp post 1 to be refracted by the lens 3 at different angles or to produce different illumination effects.

[0020] Refer to the attached Figures 1 to 3 The lamp post 1 includes a column 1-1, which is cylindrical, a lamp trough 1-2 opened at the top of the column 1-1, and lamp beads 1-3 installed inside the lamp trough 1-2. The size of the lamp trough 1-3 matches the lamp beads 1-3, and the top of the lamp beads 1-3 does not exceed the size of the lamp trough 1-3. The side wall of the lamp trough 1-2 is provided with an inclined surface 1-4 for refracting the light from the side of the lamp beads 1-3 onto the lens 3, and the inclined surface 1-4 is a conical shape expanding outward.

[0021] Refer to the attached Figures 1 to 3 The lampshade 2 includes a cover body 2-1 sleeved on the outside of the column 1-1, and a ball 2-2 installed on the inner wall of the cover body 2-1. There are more than two balls 2-2. A spiral groove 1-5 cooperating with the ball 2-2 is provided on the outside of the column 1-1. The spiral groove 1-5 is distributed upward in a spiral along the outer surface of the column 1-1. When the cover body 2-1 slides along the outside of the column 1-1, the ball 2-2 moves along the spiral groove 1-5. The movement of the ball in the spiral groove 1-5 will force the cover body 2-1 to rotate.

[0022] Refer to the attached Figures 1 to 3 : Lens 3 is fixed on the top of the cover body 2-1 and corresponds to the lamp bead 1-3. The lens 3 covers the lamp bead 1-3. The lens 3 is configured as a semicircular shell composed of 3 to 8 arc-shaped lenses. The size of each arc-shaped lens can be set to be the same or different as needed.

[0023] Refer to the attached Figures 1 to 3 An elastic member 4 for increasing the rotation frequency of the cover 2-1 is installed between the column 1-1 and the cover 2-1. The elastic member 4 includes an upper ring 4-1 rotatably connected to the outside of the cover 2-1, a lower ring 4-2 fixed to the outside of the column 1-1, and a spring 4-3 fixedly connected between the upper ring 4-1 and the lower ring 4-2. The spring 4-3 can drive the cover 2-1 to slide back and forth on the outside of the column 1-1, thereby causing the lens 3 on the cover 2-1 to rotate back and forth.

[0024] When in use, the lamp post 1 is fixed on the body of the car, and the vibration of the car during driving and the inertia generated during acceleration and deceleration are transmitted to the lampshade 2. The cover body 2-1 moves along the axial direction of the column 1-1 due to inertia. When the cover body 2-1 moves, the ball 2-2 moves along the spiral groove 1-5 to drive the cover body 2-1 to rotate. The rotation of the cover body 2-1 drives the lens 3 to rotate. The refraction angle and irradiation range of the light emitted by the lamp bead 1-3 through the lens 3 change dynamically, so as to achieve the purpose of expanding the irradiation coverage area and reminding others to pay attention. The elastic member 4 can make the cover body 2-1 slide back and forth on the outside of the column 1-1, so that the lens 3 on the cover body 2-1 rotates back and forth, thereby improving the frequency and effect of dynamic changes in light.
