The invention relates to a crumple type hinge assembly and an automobile, the crumple type hinge assembly comprises a hinge arm and a fixing plate, the fixing plate is provided with a first end and a second end which are located on the two opposite sides, the first end is pivotally connected with the hinge arm, and the second end is used for being connected with an automobile body; a first bending part and a second bending part are arranged on the fixing plate in a spaced mode in the direction from the first end to the second end, the bending direction of the first bending part is opposite to the bending direction of the second bending part, and the rigidity of the second bending part is larger than that of the first bending part; a crumple part is arranged between the first bending part and the second bending part, and the rigidity of the first bending part is larger than that of the crumple part. According to the hinge assembly, the crumple energy-absorbing part is additionally arranged through the crumple part, the crumple part can conduct first-time energy-absorbing deformation before the first bent part, and in the deformation process of the first bent part and the second bent part, the crumple part can conduct second-time energy-absorbing deformation, so that the crumple energy-absorbing effect of the hinge assembly is further improved, and the service life of the hinge assembly is prolonged. And the passive safety performance of the automobile can be improved.
本发明涉及一种溃缩式铰链组件及汽车,溃缩式铰链组件包括铰接臂和固定板,固定板具有位于相对两侧的第一端和第二端,第一端与铰接臂枢转相连,第二端用于与汽车主体相连;固定板沿从第一端到第二端的方向间隔设有第一折弯部和第二折弯部,第一折弯部的折弯方向与第二折弯部的折弯方向相反,且第二折弯部的刚度大于第一折弯部的刚度;第一折弯部与第二折弯部之间设有溃缩部,第一折弯部的刚度大于溃缩部的刚度。本发明通过溃缩部增加了溃缩吸能部位,溃缩部能够先于第一折弯部进行第一次吸能形变,并在第一折弯部与第二折弯部变形过程中,溃缩部能够进行第二次吸能形变,从而进一步提高铰链组件的溃缩吸能效果,有利于提高汽车的被动安全性能。
