The invention discloses a vehicle body side protection structure of an electric vehicle and the electric vehicle. The vehicle body side protection structure comprises a doorsill beam, a front longitudinal beam rear section, a seat front cross beam and a collision force transmission piece. The front longitudinal beam rear section and the threshold beam are opposite in the transverse direction and are spaced, and the seat front cross beam extends in the transverse direction of a vehicle body and is connected with the front longitudinal beam rear section. The collision force transmission piece is connected with at least one of the threshold beam, the seat front cross beam and the front longitudinal beam rear section in the transverse direction, so that the threshold beam transmits collision force to at least one of the seat front cross beam and the front longitudinal beam rear section. Therefore, by arranging the collision force transmission piece, the force generated after the threshold beam is collided, extruded and deformed can be transmitted to the seat front cross beam and/or the front longitudinal beam rear section, so that local excessive deformation of the vehicle body side protection structure is reduced, the safety of a driver and passengers is improved, and the vehicle can have the high side column collision protection requirement.
本发明公开了一种电动车的车身侧防护结构和电动车,车身侧防护结构包括:门槛梁、前纵梁后段、座椅前横梁、碰撞力传递件。所述前纵梁后段与所述门槛梁在横向上相对并且间隔开,所述座椅前横梁沿车身的横向延伸,所述座椅前横梁与所述前纵梁后段连接。碰撞力传递件在横向上连接门槛梁、座椅前横梁和前纵梁后段两者中的至少一个,以使所述门槛梁向所述座椅前横梁和所述前纵梁后段两者中的至少一个传递碰撞力。由此,通过设置碰撞力传递件,可以将门槛梁受碰撞挤压变形后的力传递给座椅前横梁和/或前纵梁后段,以降低车身侧防护结构局部过度变形,提高驾乘人员的安全性,以使车辆能够具有较高的侧面柱碰防护要求。
