The invention discloses a vehicle body assembly and an electric vehicle with the same. The vehicle body assembly includes: a sill outer panel; the doorsill outer plate is connected with the doorsill inner plate to form a doorsill beam cavity; the doorsill outer plate and the doorsill inner plate are both connected with the column A; the doorsill reinforcing beam is arranged in the doorsill beam cavity, and the doorsill reinforcing beam is fixedly connected with the doorsill outer plate and the doorsill inner plate. According to the vehicle body assembly, the force transmission channel from the column A to the doorsill outer plate to the doorsill reinforcing beam is formed, so that force is gradually transmitted when the vehicle body assembly is subjected to forward collision and lateral collision, and stress concentration is avoided. In the force transmission process, the components can collapse to absorb energy. According to the structure, the structural stability of the vehicle body assembly can be improved, and the energy absorption effect of the doorsill stiffening beam is improved. In the force transmission process, the structure is beneficial to improving the resistance of the threshold structure during collision, and the force transmission efficiency is improved.
本发明公开了一种车身总成及具有其的电动车。车身总成包括:门槛外板;门槛内板,所述门槛外板与所述门槛内板相连形成门槛梁腔;A柱,所述门槛外板以及所述门槛内板均与所述A柱连接;门槛加强梁,所述门槛加强梁设置在所述门槛梁腔内,且所述门槛加强梁与所述门槛外板以及所述门槛内板固定连接。根据本申请实施例的车身总成,通过形成从A柱至门槛外板至门槛加强梁的传力通道,在受到前向碰撞、侧向碰撞时,逐次传递,避免应力集中。在传力过程中,上述部件可以溃缩吸能。上述结构可以提高车身总成的结构稳定性,又提高门槛加强梁的吸能效果。在传力过程中,上述结构还有利于提升碰撞时门槛结构抵抗力,提高传力效率。
