车灯反射镜的逆向设计与质量检验

车灯的配光性能对行车安全性具有重要影响,必须达到严格的质量标准。反射镜是影响车灯配光性能的核心组件,因此具有较高的设计要求。逆向设计技术是消化吸收先进技术并缩短产品开发周期的重要手段,将其应用于车灯反射镜的设计开发中能降低设计难度并缩短开发周期。文章结合反射镜的结构特点分析了逆向设计的思路,并从过点精度、拔模、壁厚和装配干涉四个方面对设计数据进行质量检验,确保最终的反射镜产品能够满足设计要求和使用需求。文章介绍的反射镜产品逆向设计和质量检验技术,对其他产品的逆向设计和开发具有很好的参考价值。

The light distribution performance of the automobile lamp has an important impact on the safety of driving, which must meet strict quality standards. Reflector is the core component that affects the light distribution performance of automobile lamp, so it has high design requirements. Reverse design technology is an important means to assimilate advanced technology and shorten the product development cycle. Its application in the development of automobile lamp reflector can reduce the design difficulty and shorten the development cycle. According to the structural characteristics of the reflector, the basic flow of reverse design of the reflector is presented and the design data of the reflector is verified from four aspects, namely, the precision of point-establishment, draft angle, wall thickness and assembly interference, to ensure that the final product can meet the design requirements and usage requirements. The proposed reverse design and quality inspection technology of the reflector product is valuable for other products.
