The invention discloses a quick replacement mechanism and system for a power battery of a new energy automobile and the automobile. The quick replacement mechanism comprises a base, a worm, a worm wheel, a clamping assembly and a transmission assembly, wherein the base is used for being fixed to an automobile body, and the base has a first direction and a second direction which are arranged in a crossed mode; the worm is rotationally installed on the base along the axis in the first direction; the worm wheel is rotationally mounted on the base and is meshed with the worm; the clamping assemblycomprises two clamping parts which are oppositely arranged in the second direction, at least one of the two clamping parts is movably installed on the base in the second direction so as to enable thetwo clamping parts to have moving strokes which are close to each other and far away from each other, and when the two clamping parts are close to each other, the two clamping parts jointly clamp andfix the power battery; and the transmission assembly is connected with the worm wheel and the movably-arranged clamping part so as to convert rotation of the worm wheel into movement of the movably-arranged clamping part in the second direction. Therefore, clamping and loosening of the power battery can be completed only by rotating the worm, and quick replacement of the power battery is achieved.
本发明公开一种新能源汽车动力电池的快换机构、系统和汽车,包括基座、蜗杆、蜗轮、夹持组件和传动组件,基座用于固定至车体,基座具有呈交叉设置的第一方向及第二方向;蜗杆沿第一方向轴线转动安装于基座;蜗轮转动安装于基座,蜗轮与蜗杆相啮合;夹持组件包括沿第二方向呈相对设置的两个夹持部,两个夹持部中的至少一个沿第二方向活动安装在基座,以使得两个夹持部具有相互靠近和相互远离的移动行程,其中,两个夹持部在相互靠近时,共同夹持固定动力电池;传动组件连接蜗轮和活动设置的夹持部,以将蜗轮的转动,转换为活动设置的夹持部沿第二方向的移动。从而只需要转动蜗杆即可完成动力电池的夹持和松开,从而实现动力电池的快速更换。
