The invention provides an anti-collision mechanism for a power battery of an electric vehicle. The anti-collision mechanism comprises a vehicle frame and a bracket assembly of a power battery pack mounted on the vehicle frame, wherein the front end and the rear end of the power battery pack are respectively provided with a front wheel and a rear wheel, a bracket assembly is arranged between the power battery pack and the frame, the lower end of the frame is provided with an arc-shaped protective plate assembly at the front end of the front wheel, and the lower end of the frame is provided withan inclined protective plate assembly between the power battery pack and the front wheel. The arc-shaped protection plate assembly and the inclined protection plate assembly can push and flatten protrusions on the ground, the protrusions are prevented from damaging a power battery pack and other parts arranged on the frame, the bracket assembly plays a role in fixing, damping and buffering the power battery pack, and meanwhile the power battery pack is prevented from being damaged by the protrusions; and the impact force of the ground bulges which cannot be completely avoided by the two frontguard plate assemblies can be absorbed, so the power battery pack is effectively protected.

    本发明提供了一种电动汽车动力电池防撞机构,包括车架及安装在车架上的动力电池包的托架组件。动力电池包的前后端分别安装有前车轮和后车轮,动力电池包与车架之间设置有托架组件,车架的下端于前车轮的前端位置设置有弧形护板组件,车架的下端于动力电池包和前车轮的中间位置设置有斜护板组件。弧形护板组件和斜护板组件可以推平地面凸出物,防止凸出物对设置在车架上的动力电池包以及其他零部件造成损伤,托架组件对动力电池包起到固定和减震缓冲的作用,同时,也可以吸收前边两个护板组件没能完全避免的地面凸出物的撞击力,有效保护动力电池包。
