The invention discloses a bottom hanging type battery pack and an electric automobile, the bottom hanging type battery pack is used for being detachably connected with a locking mechanism on a longitudinal beam of the electric automobile from top to bottom, and the bottom hanging type battery pack comprises a battery pack box body and a plurality of hanging pieces; a groove which is sunken towards the interior of the battery pack box body is formed in the position, corresponding to the longitudinal beam, of the bottom of the battery pack box body, and the two ends of each hanging piece are connected with the side wall of the groove or the mounting bracket in the groove to form a hanging part in the middle of the hanging piece; and the battery pack box body is detachably connected to the longitudinal beam through matching of the hanging parts of the plurality of hanging pieces and the locking mechanism. The battery pack is in locking connection with the locking mechanism of the electric automobile through the hooking pieces with the two ends fixed, even if the hooking pieces deviate in the horizontal direction relative to the locking mechanism, the hooking pieces cannot be disengaged from the locking mechanism, connection between the locking mechanism and the hooking pieces is more stable, and the bearing effect of the hooking pieces is better.

    本发明公开了一种底部挂接式电池包及电动汽车,用于以自上而下的方向与电动汽车纵梁上的锁止机构可拆卸连接,所述底部挂接式电池包包括电池包箱体和若干挂接件;所述电池包箱体的底部对应所述纵梁的位置处设有朝向所述电池包箱体内部凹陷的凹槽,若干个所述挂接件的两端均与所述凹槽的侧壁或所述凹槽内的安装支架连接并形成其中间的挂接部,所述电池包箱体通过若干个所述挂接件的挂接部与所述锁止机构配合可拆卸连接于所述纵梁。电池包通过两端固定的挂接件与电动汽车的锁止机构实现锁止连接,即使挂接件相对于锁止机构发生水平方向上的偏移,挂接件也不会从锁止机构内脱出,锁止机构与挂接件之间的连接更加稳定,挂接件承载效果更好。
