The invention discloses an electric vehicle battery compartment lifting device which comprises a first lifting mechanism and a second lifting mechanism, and the two lifting mechanisms each comprise a sliding assembly and a swing arm; the sliding assembly is in driving connection with the driving mechanism, the swing arm is arranged between the frame and the battery bin, and the battery bin is hung below the frame through the swing arm. The two swing arms are provided with opposite translation ends and rotating ends, the translation ends and the rotating ends have height difference, the translation ends of the two swing arms are fixedly connected with the sliding parts of the same sliding assembly, the rotating ends of the two swing arms are hinged to the frame at intervals, and the two swing arms are symmetrically arranged along the center line of the battery bin and can synchronously swing between the initial positions and the unfolding positions in a reciprocating mode. The lifting stability and accuracy of the battery compartment can be improved, the lower space of the vehicle body can be fully utilized, and the effective lifting stroke of the battery compartment can be obtained in the limited vertical space.
本发明公开一种电动汽车电池仓升降装置,包括第一升降机构及第二升降机构,两升降机构均包括滑动组件和摆臂;所述滑动组件与驱动机构驱动连接,所述摆臂设于车架与电池仓之间,电池仓通过摆臂悬挂于车架下方;两摆臂均具有相对的平动端和转动端,且平动端与转动端具有高度差,两摆臂的平动端与同组滑动组件的滑动件固接,其转动端与车架间隔铰接,两个摆臂沿电池仓的中线对称设置,并能够在各自的初始位与展开位之间同步往复摆动。本发明能够提高电池仓升降的平稳性和精确性,且能充分利用车体下部空间,使电池仓在有限的竖向空间内获得有效的升降行程。
