The miniature electric vehicle comprises a vehicle underframe, a main driver seat and a co-driver seat, the main driver seat and the co-driver seat are arranged on the vehicle underframe, two rear wheels are of two independent hub motor structures, and hub motors are installed on oblique suspensions through independent rear axles. At least one battery bin is arranged below the main driver seat and the co-driver seat and at the position, between the two independent rear axles, of the tail of the vehicle underframe, battery packs are arranged in the battery bins and located on the vehicle underframe, and each battery pack can independently supply power to the corresponding hub motor. The design scheme that a plurality of battery packs are independently detachable and are independently charged and supplied with power is adopted, so that the electric energy supply of the micro electric vehicle is continuous; by adopting the split type rear axle design and the hub motor scheme, the position space of the original integral type rear axle on the vehicle chassis is completely released, so that the mounting space of the battery pack is greatly increased, the design capacity of the battery pack is improved, and the endurance of a single whole is improved.

    本发明公开了一种微型电动汽车,包括车底架,设置在车底架上的主驾驶座与副驾驶座,所述两个后轮为两个独立的轮毂电机结构,且轮毂电机通过独立后桥安装在斜向悬挂上,所述主驾驶座与副驾驶座的下方、车底架的尾部处于两个独立后桥之间的位置分别设有至少一个电池仓,电池仓内设有电池包,且电池包处于车底架之上,每个电池包可为轮毂电机独立供电。本发明采用多个电池包独立可拆卸、独立充电与供电的设计方案,使得微型电动汽车的电能提供具有连续性;采用分体式的后桥设计以及采用轮毂电机的方案,使得原整体式后桥在车底架的位置空间全部释放,从而大大增加了电池包的安装空间,继而提高电池包的设计容量,从而提高单整体续航。
