The invention provides a vehicle body force transmission structure, a vehicle body and a vehicle, the vehicle body force transmission structure comprises an upper longitudinal beam, an A column assembly and a reinforcing part, the upper longitudinal beam is connected to the A column assembly, the upper longitudinal beam and the A column assembly jointly define an energy absorption cavity, and the reinforcing part is located in the energy absorption cavity and connected to the A column assembly and the upper longitudinal beam. In this way, the energy absorption cavity defined by the upper longitudinal beam and the A column assembly can absorb and disperse impact energy. In addition, the strength of the structure can be enhanced through the reinforcer, the connection strength of the upper longitudinal beam and the A column assembly can be enhanced, the stability of the vehicle body force transmission structure can be improved, and then the risk that the vehicle body force transmission structure fails is reduced. Moreover, the reinforcing part is located in the energy absorption cavity and connected to the A column assembly and the upper longitudinal beam, the upper longitudinal beam can transmit force to the A column assembly through the reinforcing part, and therefore the vehicle body force transmission structure can disperse external impact energy.
本申请提供一种车身传力结构、车身和车辆,车身传力结构包括上纵梁、A柱总成和加强件,上纵梁连接于A柱总成,上纵梁和A柱总成共同围合形成吸能腔,加强件位于吸能腔内并分别连接于A柱总成与上纵梁。如此,上纵梁和A柱总成共同围合形成的吸能腔可以吸收和分散冲击能量。此外,加强件可以增强结构的强度,有助于加强上纵梁和A柱总成的连接强度,从而有助于提高车身传力结构的稳定性,进而降低车身传力结构失效的风险。而且,加强件位于吸能腔内并分别连接于A柱总成与上纵梁,有助于上纵梁通过加强件向A柱总成传力,从而有助于车身传力结构分散外部冲击的能量。
