The invention discloses a cover plate of a driving assembly shell, a driving assembly with the cover plate and a vehicle. The driving assembly shell comprises a lower shell and a cover plate, a mounting opening is formed in the lower shell, and the cover plate covers the mounting opening. The cover plate comprises a central arch area and a mounting area, the mounting area is of an annular structure arranged around the central arch area, the mounting area is used for being in contact with and connected with the lower shell, and the central arch area comprises a plurality of curved plate areas arched from the periphery to the center in the direction away from a mounting opening. According to the electric control cover plate, by arranging the center arch area and the mounting area, the modulus of the electric control cover plate can be increased to a certain degree, the inherent frequency of the electric control cover plate is increased, the inherent frequency of the electric control cover plate is far away from the external excitation vibration frequency caused by vibration of the driving motor, and therefore resonance generated by the electric control cover plate and the driving motor is reduced; vibration and noise generated when the driving assembly works are reduced, and resonance fatigue borne by the driving assembly structure is reduced.

    本发明公开了一种驱动总成壳体的盖板、具有其的驱动总成及车辆。所述驱动总成壳体包括下壳体和盖板,下壳体上设有安装口,盖板盖合在安装口处。所述盖板包括中心拱区和安装区,安装区为环绕中心拱区设置的环形结构,安装区用于与下壳体接触并连接,中心拱区包括多个从四周到中心朝向远离安装口的方向拱起的曲面板区。本申请的电控盖板,通过设置中心拱区和安装区,可以一定程度增大电控盖板模量且增大电控盖板的固有频率,使电控盖板的固有频率远离驱动电机振动带来的外激励振动频率,从而减少电控盖板与驱动电机的产生共振,降低驱动总成工作时的振动和噪音,减少驱动总成结构受到的共振疲劳。
