The invention discloses a bracket assembly, a battery pack and an electric automobile, and belongs to a grounding technology in the field of electric automobiles. The bracket assembly comprises a bracket body, the bracket body is arranged on the electric vehicle and used for installing and fixing the battery pack, the bracket assembly further comprises a grounding device, the grounding device is used for guiding charges on the battery pack out of the bracket assembly and comprises an installation base and a conductive assembly, the installation base is connected to the bracket body, and the conductive assembly is arranged on the installation base. And the conductive component is movably connected to the mounting seat and is used for guiding charges of the battery pack shell out of the bracket assembly. The conductive assembly is movably arranged on the mounting seat, and when the battery pack generates relative displacement relative to the bracket main body, the conductive assembly can move relative to the bracket main body along with the battery pack within a certain range, so that the electric connection relation with the battery pack is better maintained; and the stability and the reliability of the electric connection between the grounding device and the battery pack are improved.

    本发明公开了一种托架总成、电池包及电动汽车,属于电动汽车领域的接地技术。托架总成包括托架主体,托架主体设于电动汽车上,托架主体用于安装固定电池包,托架总成还包括接地装置,接地装置用于将电池包上的电荷导出至托架总成的外部,接地装置包括安装座和导电组件,安装座连接于托架主体上,导电组件活动连接于安装座上,导电组件用于将电池包壳体的电荷导出到托架总成的外部。本发明将导电组件活动设置于安装座上,当电池包相对于托架主体产生相对位移时,导电组件能够在一定范围内随电池包一起相对于托架主体运动,从而更好地保持与电池包的电连接关系,提高了接地装置与电池包的电连接的稳定性和可靠性。
