The front hatch cover hinge installation structure of an automobile includes front hatch cover hinge and front hatch cover hinge reinforcement plate. The technical points of the structure are as follows: installation bolts are welded on the front hatch cover hinge reinforcement plate, the front hatch cover hinge reinforcement plate is welded to the front hatch cover inner plate, and the front hatch cover inner plate is provided with installation holes matching with installation bolts. The installation bolt is a round head bolt. Elastic fins are welded on the front hatch cover hinge reinforcement plate, and the installation bolts are welded on the front hatch cover hinge reinforcement plate through the elastic fins. The utility model can increase the distance between the front hatch cover outer plate and the hard point of the front hatch cover hinge installation by changing the convex welding nut on the front hatch cover hinge reinforcement plate to the flat head welding bolt, and effectively improve the problem that the former front hatch cover hinge installation structure is not conducive to the vehicle's impact protection performance against pedestrians. The structure of the utility model can also make the installation bolt have a small adjustment allowance, and can be conveniently positioned when the hinge is installed, thus improving the installation efficiency and assembly accuracy.

一种汽车前舱盖铰链安装结构
本技术涉及汽车前舱盖结构,具体涉及一种汽车前舱盖铰链安装结构。
技术介绍
随着汽车技术的发展,汽车安全性越来越被消费者和汽车厂家所重视。在汽车前舱盖设计时,汽车对行人的碰撞保护性能作为一项重要考核目标也越来越被重视,同时汽车对行人的碰撞保护性能将作为C-NCAP(中国新车评价规程)的一项重要测试内容,用来平定汽车安全星级。在汽车前舱盖设计时,由于受汽车造型影响,前舱盖铰链在前舱盖侧的安装点往往会布置在行人碰撞保护区域内侧。前舱盖铰链以往的安装结构如图一所示,前舱盖铰链加强板上焊接两个焊接螺母,前舱盖铰链通过两个组合螺栓安装到前舱盖铰链加强板上。此安装结构由于前舱盖铰链安装后,组合螺栓会凸出前舱盖铰链加强板上的凸焊螺母一定高度,当前舱盖铰链安装点受造型影响布置在行人碰撞保护区域内时,此种前舱盖铰链安装结构会减小前舱盖外板到前舱盖铰链安装硬点的距离,不利于汽车对行人的碰撞保护性能。为此需要对前舱盖铰链在前舱盖侧的安装结构进行改进,来提升汽车对行人的碰撞保护性能。
