The invention provides a connecting mechanism for fixing a battery pack. The connecting mechanism comprises a limiting seat, a floating nut, a guide piece and a fixing piece, the limiting seat is fixed on a frame, the limiting seat is provided with a limiting cavity and a first through hole, and the limiting cavity is communicated with the first through hole. The floating nut is embedded in the limiting cavity, one end of the fixing piece penetrates through the first through hole and then is movably connected with the floating nut, and an inner hexagonal connecting groove is formed in the end portion of the other end of the fixing piece. The guide part is arranged on a shell of the battery pack, the guide part is used for limiting the moving direction of the fixing part, and the fixing part is embedded in an inner cavity of the guide part. And when the fixing piece and the floating nut rotate, the limiting seat clamps or loosens the floating nut, and the fixing piece and the floating nut are screwed or separated, so that the battery pack is fixed or separated from the frame. According to the invention, the convenience of fixing or dismounting the battery pack can be improved.

    本发明提供一种用于电池包固定的连接机构,包括:限位座、浮动螺母、导向件和固定件。所述限位座固定在车架上,限位座设有限位腔和第一通孔,所述限位腔与所述第一通孔相连通。浮动螺母嵌设在所述限位腔内,固定件的一端贯穿所述第一通孔后与浮动螺母活动连接,固定件的另一端的端部设有内六角连接槽。导向件设置在电池包的壳体上,导向件用于对固定件的运动方向进行限位,固定件嵌设在导向件的内腔中。在固定件与浮动螺母旋转时,限位座卡紧或松开所述浮动螺母,并使固定件与所述浮动螺母旋紧或脱离,进而使电池包固定或脱离车架。本发明能提高电池包固定或拆卸的便捷性。
