Technical Problem

[0003]传统汽车尾门铰链多缺乏专门的缓冲与防异响设计,长期使用后,铰链连接部位的零部件易因磨损、间隙增大产生相对摩擦或碰撞,尤其在车辆行驶颠簸路段、尾门开关瞬间,易出现明显异响,影响驾驶舒适性与用户使用体验,因此需要进行改进

Benefits of technology

1、本实用新型中,通过在连接套一和连接套二处分别设置缓冲垫圈一和缓冲垫圈二,能有效吸收尾门开关及车辆行驶时的振动,减少零部件间的直接摩擦与碰撞,从根源上抑制异响产生,提升驾驶与使用的静谧性,同时轴销配合插块、弹簧与限位块的结构设计,不仅实现了铰接件一与铰接件二的稳固连接,还便于后期维护。
