Optical system subassembly for automobile lighting

Abstract

The invention relates to an optical system subassembly for automobile lighting. The optical system subassembly comprises a light shielding device and a baffle horizontally arranged above the light shielding device. The baffle is connected with the light shielding device through a clamping structure, the clamping structure comprises a plurality of clamping grooves and plugs, and the clamping grooves and the plugs are arranged on the baffle. A stamping bridge is arranged on the light shielding device, the stamping bridge is matched with the plugs for limiting, a plurality of transom windows arearranged on the light shielding device, and the transom windows are connected with the clamping grooves in a matched and clamped mode. A clamping mode is adopted for fixing, and rapid assembly is facilitated. The size can be adjusted according to actual product requirements, for example, when a wide-body lens module is designed, the wall thickness of the baffle can be increased; when a double-light module is designed, a thin-wall baffle can be considered to be adopted; and the material can be changed according to the positions of the clamping grooves in the clamping structure in the baffle andthe elastic deformation of the clamping grooves in the clamping process. For the requirement of material reflectivity in optical design, surface treatment can be carried out before assembly.

Description

technical field [0001] The invention belongs to the technical field of automobile lighting, and relates to an optical system subassembly for automobile lighting. Background technique [0002] The low beam function in the vehicle headlight lighting system is mainly used in townships and urban roads to avoid the bad phenomenon of driver's visual glare in the process of meeting cars. In the modern low-beam lighting system, the shape of the "Z" cut-off line is the key part to form the low-beam lighting effect. In order to fix the shape inside the system and form a certain angle relationship with the light source, so as to achieve the purpose of low beam, currently more installation methods are mainly bracket assembly type and plastic integrated type, but these two methods have design Insufficient on. For the bracket assembly, the shape of the cut-off line can be formed by a sheet metal stamping process to form a metal cut-off line baffle, and then the metal cut-off line baffle...
