The invention discloses a battery pack compact electric driving force unit which comprises a motor and a battery pack, the motor is installed on a base, the battery pack is supported on the upper portion of the motor through a supporting frame, and the supporting frame is shaped around the periphery of the motor. An arch-shaped supporting portion matched with the upper portion of the motor is formed on the upper portion of the supporting frame, the bottom of the battery pack is provided with a concave portion matched with the arch-shaped supporting portion, and the arch-shaped supporting portion of the supporting frame is supported in the concave portion of the battery pack. The overall height of the electric driving force unit can be reduced on the premise that the endurance of the battery pack is not reduced, so that the overall installation size limitation is met.

    本发明公开了一种电池包紧凑化电驱动力单元,包括电机和电池包,所述电机安装在底座上,所述电池包通过支撑框架支撑于所述电机的上部,所述支撑框架围绕所述电机的外周进行造型,并在该支撑框架的上部形成与电机的上部适配的拱形支撑部,所述电池包的底部具有与所述拱形支撑部适配的凹陷部,所述支撑框架的拱形支撑部支撑于所述电池包的凹陷部内。本发明能够在不减少电池包续航的前提下,降低该电驱动力单元的整体高度,以满足整体安装尺寸限制。
