The invention belongs to the technical field of automobile bodies, and particularly relates to an automobile rear shock absorber connecting structure which comprises a self-tapping locking threaded sleeve, the self-tapping locking threaded sleeve is arranged in a mounting hole in an integrally die-cast rear floor, and when a rear shock absorber is mounted, a mounting bolt penetrates through a through hole of the rear shock absorber and then is screwed into the self-tapping locking threaded sleeve in a threaded mode; the self-tapping locking thread bushing comprises a thread bushing body and a flange face arranged at one end of the thread bushing body. An inner cavity of the thread bushing body is provided with an internal thread structure, and the internal thread structure is sequentially composed of a conventional thread area and a thread self-locking area in the axial direction of the thread bushing body. According to the technical scheme, when the rear shock absorber connecting structure is located on the aluminum alloy die casting, the self-tapping locking threaded sleeve is adopted for an installation point, and a specific internal thread structure is combined, so that high connection strength, simple structure and convenient assembly are achieved, and the risk of connection looseness after the rear shock absorber is used for a long time can be reduced.

    本发明属于车身技术领域,具体涉及一种汽车后减震器连接结构,包括自攻锁紧螺纹套,自攻锁紧螺纹套布置于一体压铸成型后地板上的安装孔内,后减震器安装时,使用安装螺栓穿过后减震器的通孔后,螺纹拧入自攻锁紧螺纹套内;自攻锁紧螺纹套包括螺纹套本体及设置于螺纹套本体一端的法兰面;螺纹套本体的内腔设置有内螺纹结构,内螺纹结构沿螺纹套本体的轴向依次由常规螺纹区和螺纹自锁区组成。本技术方案的后减震器连接结构位于铝合金压铸件上时,安装点采用自攻锁紧螺纹套,并结合特定的内螺纹结构,实现连接强度高,结构简单,装配方便,可降低后减震器长时间使用后连接松动的风险。
