Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle lamps, in particular to a light adjustment mechanism for a motorcycle lamp. Background Art

[0002] Most motorcycle lights are LED lights, which are mainly used for lighting and signaling. The light emitted by the lights can illuminate the road conditions in front of the vehicle, allowing the driver to drive safely at night. They are usually installed at the front of the vehicle.

[0003] A light adjustment mechanism for a motorcycle lamp disclosed in the Chinese utility model patent application disclosure specification CN210592249U can conveniently drive the polymer cover to move forward or backward in the first groove by twisting the cap, so as to control the convergence and diffusion of the front light through the distance blocked by the reflector. It is highly practical. Although the forward and backward movement of the reflector can be controlled to solve the convergence and diffusion of the irradiated light, in actual use, in order to ensure the appearance, an outer frame will be installed on the outside of the motorcycle lamp to seal it and make it closed as a whole. The adjustment mechanism is manually operated, which is cumbersome to operate. It is also difficult to adjust during driving. Moreover, the convergence and diffusion angles of the irradiated light are also relatively limited by relying only on the forward and backward movement of the polymer cover. Therefore, the present application provides a light adjustment mechanism for a motorcycle lamp to meet the needs. Utility Model Content

In addition, by setting the guide rod, the front end passes through the guide hole opened on the inner side of the first cover ring and the second cover ring, so that the installation angles of the main body cover ring and the first cover ring and the second cover ring are in a straight line, so that it can be more efficient when aggregating the light.

[0019] By setting up the design of telescopic motor A and telescopic motor B, the telescopic rod A and telescopic rod B can be driven to rotate in a threaded manner, and the telescopic block A and telescopic block B can be laterally displaced along the threads on their outer sides, thereby adjusting the mutual distances between the main body cover ring, the first cover ring and the second cover ring. Therefore, the focusing and beaming effects of the irradiated light can be adjusted according to the needs during riding, making it more efficient in focusing and beaming and more convenient to operate.

[0020] By setting a symmetrical design of the reflective lens, the irradiation angle of the aggregated light can be adjusted. When it is necessary to irradiate farther, the tilt motor starts working to drive the distance between the front ends of the upper and lower angle plates to be reduced, thereby reducing the diffusion angle of the light and combining the reflected light to irradiate farther in a straight line. When it is necessary to expand the irradiation angle, the above steps are performed in reverse to expand the distance between the front ends of the upper and lower angle plates, thereby achieving the effect of diffuse irradiation. The entire operation step can be electrically controlled through a three-control switch, and the operation is also more convenient.

[0021] In summary, the utility model has the advantages of improving the efficiency of focusing and beaming the irradiating light, and can adjust the diffusion and beaming of the irradiating light according to real-time changes during riding, thereby improving the overall convenience of operation.

By setting the condenser A305 and the condenser B403, the condenser angles of the two can aggregate the irradiation light emitted by the LED lamp 201 to reduce the dispersion effect of the light, and then the light is concentrated and emitted through the aggregation cover 404 to improve the overall irradiation brightness. Secondly, through the symmetrical design of the reflective lens 802, the irradiation angle of the aggregated light can be adjusted. When it is necessary to irradiate farther, the tilt motor 805 starts to work, driving the distance between the front ends of the upper and lower angle plates 801 to be reduced, thereby reducing the diffusion angle of the light, and focusing the reflected light to irradiate farther in a straight line. When it is necessary to expand the irradiation angle, the above steps are reversed to expand the distance between the front ends of the upper and lower angle plates 801, thereby achieving the effect of diffuse irradiation. The entire operation steps can be controlled by a switch, so that the focusing and beaming effects of the irradiation light can be adjusted in real time according to the needs during riding, thereby improving the convenience of operation.
