汽车外后视镜布置策略

Layout Strategy of Outside Rearview Mirror

汽车外后视镜视野直接影响到行车安全性。阐述了汽车外后视镜基座的布置要求及常见的外后视镜主观视野的评估准则。从后视镜区域整体布置集成的角度,考虑安装便利性、外观特性以及成本质量等评价因素,分析了外后视镜布置在前门角落塑料基座上(Mirror patch),布置在前门角落水切面上(Mirror on belt)以及布置在前门钣金上(Mirror under belt)3类布置策略的优劣。以某项目滚压门框为例,对每种布置策略的综合成本以及外观特征进行了评估与对比。经对比得出,考虑成本质量,后视镜安装在门框加强框的方案更优;考虑造型多样性,后视镜安装在门内板的方案更优。

The view of the outside rearview mirror(OSRVM)directly affects the driving safety.The layout requirements of the base of OSRVM and the evaluation criteria of the common subjective view of OSRVM are described.From the perspective of the integration of the overall layout of OSRVM area,considering the evaluation factors of installation convenience,appearance characteristics and cost quality,this paper analyzes the advantages and disadvantages of three kinds of layout strategies of OSRVM on the front door corner plastic base(Mirror patch),on the front door corner water cut plane(Mirror on belt)and on the front door sheet metal(Mirror under belt).Taking an APH doorframe project as example,the comprehensive cost and appearance characteristics of each layout strategy are evaluated and compared.By comparison,considering the cost and weight,it is better to install the mirror on the door frame;while installed on the door inner panel will bring more diverse of the rearview mirror design.
