The invention discloses a protection assembly of a quick-change device, the quick-change device and an electric vehicle, the quick-change device comprises a vehicle end connecting part and a battery end connecting part connected with the vehicle end connecting part, and the connection between the vehicle end connecting part and the battery end connecting part comprises electric connection; the protection assembly is used for shielding at least part of an electric connection area formed by electric connection between the vehicle end connection part and the battery end connection part; the protection assembly comprises a plate body, a flow guide groove is formed in at least one side of the plate body in the length direction of the plate body, and the flow guide groove inclines downwards relative to the plate body. By adopting the scheme, the protection assembly can prevent barriers such as sand and stones, rainwater and the like from entering the electric connection part to cause electric connection failure. The flow guide grooves can guide obstacles to enter or flow out of the plate body, and the obstacles are prevented from staying on the plate body. The diversion trenches incline downwards relative to the plate body, so that the downward guiding capability of the diversion trenches to obstacles is facilitated, the obstacles are prevented from being accumulated at the diversion trenches, and the diversion effect of the diversion trenches is improved.

    本发明公开了一种快换装置的防护组件、快换装置及电动车辆,快换装置包括车端连接部和与车端连接部连接的电池端连接部,且车端连接部和电池端连接部之间的连接包括电连接;防护组件用于遮挡至少部分车端连接部和电池端连接部之间电连接形成的电连接区域;防护组件包括板本体,沿着板本体的长度方向,板本体的至少一侧设有导流槽,导流槽相对板本体向下倾斜。采用本方案,防护组件能够避免沙石、雨水等障碍物进入电连接处,导致电连接失效。导流槽能够引导障碍物进入或流至板本体以外,避免障碍物滞留在板本体上。导流槽相对板本体向下倾斜,有利于导流槽对障碍物的向下引导能力,避免障碍物堆积在导流槽处,提升导流槽的导流效果。
