[0002] In the field of optical instrument manufacturing, precision machinery manufacturing and automobile parts manufacturing, high-low beam lens module is an important component. The main function of high-low beam lens module is to change the refraction angle of light by adjusting the position of the lens, so as to realize the switching of high beam and low beam. High-low beam lens module is usually composed of lens, lens bracket, decorative part and radiator. The lens is used for refracting light, the lens bracket is used for fixing the lens, the decorative part is used for beautifying and protecting the lens, and the radiator is used for heat dissipation.

[0003] The lens in the existing high-low beam lens module is mainly fixed by setting buckle or screw hole on the lens and directly fixed on the lens bracket. This assembly method can improve the positioning accuracy, but reduces the assembly efficiency. The buckle is a common fixing method, but due to the limitation of the shape and position of the buckle, the buckle is difficult to assemble, which has become a big problem in the assembly process of high-low beam lens module.
