[0002] At present, the dual-beam lens of the car is a combination of two lenses with different functions, which are used for low beam and high beam respectively, to achieve more refined and diverse lighting effects. Generally, the low beam lens in the dual-beam lens is designed to be flatter, which can produce a wide and uniform light beam, and is suitable for use in environments with good lighting conditions such as urban roads, providing good road lighting and surrounding environment perception. The high-beam lens is designed to be more focused and long-range, which can provide a stronger light beam when long-distance lighting is required, and enhance the driver's ability to recognize road conditions in the distance. Through the design of the dual-beam lens, the vehicle can achieve the best lighting effect in different driving scenarios, which not only ensures driving safety, but also improves driving comfort and convenience.

[0003] However, there are many problems with the current automotive dual-light lenses. Most automotive dual-light lenses are set up in two groups, corresponding to the low beam lamp beads and high beam lamp beads respectively. Compared with single-light irradiation, an additional set of lamp beads and lenses greatly increases the cost, and the current dual-light lenses cannot adjust the irradiation angle and have poor adaptability to various road conditions. Summary of the invention

[0004] The utility model aims to solve the problems existing in the above-mentioned prior art and provides a reflective dual-light lens device for vehicle headlights. A reflector is arranged above a single group of lamp beads, and the reflector reflects the light to a lens plate. Lenses with different effects can be arranged at different positions on the lens plate. By adjusting the angle of the reflector, the light emitted by the lamp beads is reflected to different positions on the lens plate, so as to realize the switching of high and low beam lights and the switching of illumination angles.

[0005] The utility model adopts a technical solution to solve the technical problem: the vehicle headlight reflective dual-light lens device comprises a light board, a lens board arranged at the front end of the light board and capable of installing lenses of different specifications, a reflective board rotatably arranged at the rear end of the light board, and a light source installed on the light board and located between the lens board and the reflective board. The reflective board can reflect the light of the light source to lenses of different specifications on the lens board by rotating.

[0006] For further improvement, the lens plate is rotatably connected to the front end of the light board, and the lens plate can be rotated to be perpendicular to the reflected light.

[0007] To be further improved, the front end of the lamp panel is rotatably connected with a front rotating shaft, a front frame is fixedly mounted on the front rotating shaft, and the lens panel is fixedly mounted on the front frame.

[0008] For further improvement, the rear end of the light panel is rotatably connected with a rear shaft, a rear frame is fixedly mounted on the rear shaft, and the reflector is fixedly mounted on the rear frame.

[0009] For further improvement, a driving gear for driving the reflector to rotate is fixedly installed on the rear shaft, a driven gear for driving the lens plate to rotate is fixedly installed on the front shaft, a middle shaft located between the front shaft and the rear shaft is rotatably connected to the light board, a steering gear meshing with both the driving gear and the driven gear is fixedly installed on the middle shaft, and the steering gear and the driven gear have the same specifications.

[0010] Further improvement, the transmission ratio of the driving gear and the driven gear is set so that the lens plate can always be perpendicular to the reflected light when the reflection plate rotates.

[0011] For further improvement, support plates are provided on both sides of the light panel, and the front rotating shaft, the middle rotating shaft and the rear rotating shaft are rotatably connected to the support plates.

[0012] Further improvement, the light source is an LED lamp, the top of the light source emits light and the top is a flat setting.

[0013] The beneficial effects of the utility model are as follows: the utility model can control the light to be projected to different positions of the lens plate by adjusting the angle of the reflector, thereby realizing precise control of the irradiation angle, which can greatly save the space of the lighting system, not only helping to reduce the overall weight of the lamp, but also reducing the production and maintenance costs. It has significant advantages in improving the lighting effect, optimizing the lighting function, and saving space and cost. BRIEF DESCRIPTION OF THE DRAWINGS
