The invention provides a side column collision vehicle body protection structure and an electric vehicle. The side column collision vehicle body protection structure comprises a side wall assembly and a floor assembly. The side wall assembly comprises a doorsill inner plate, a doorsill outer plate and a reinforcing piece which is assembled between the doorsill inner plate and the doorsill outer plate and is connected and fixed through a bolt assembly. The reinforcing plate is made of extruded aluminum alloy sections and is provided with a plurality of buffering cavities. According to the invention, the material and process of the reinforcer are selected, and the reinforcer is connected through the bolts, so that an obvious weight reduction effect is achieved, and meanwhile, the investment of a main engine plant on aluminum connection equipment is reduced; through the arrangement of the buffering cavity of the reinforcing piece, energy can be well absorbed, and the reinforcing piece and the middle floor can form support, so that loads are effectively transmitted to the seat cross beam; and meanwhile, by setting the position and the width of the seat cross beam, effective support can be formed for collision of the counterguard. In addition, the invention further provides the electric vehicle, and the electric vehicle has the effect of effectively supporting collision of the counterguard in the state that the weight reduction effect is remarkable.
本申请提供了一种侧面柱撞车身保护结构及电动汽车,该侧面柱撞车身保护结构包括侧围总成和地板总成;侧围总成包括:门槛内板、门槛外板、装配在门槛内板和门槛外板之间通过螺栓组件连接固定的加强件;加强板采用挤压铝合金型材,并具有多个缓冲型腔。本发明中,通过加强件材质和工艺选择并通过螺栓连接强件,具有明显的降重效果同时降低了主机厂对铝连接设备的投入;通过加强件的缓冲型腔设置,既能很好的吸收能量又能和中地板形成支撑从而有效传递载荷给座椅横梁;同时通过座椅横梁的位置和宽度设置,能够对壁障的撞击形成有效支撑。另外,本申请还提供了一种电动汽车,该电动汽车具有在减重效果显著的状态下,具备能够对壁障的撞击形成有效支撑的效果。
