The invention relates to a vehicle, a vehicle body and a force transmission structure of the vehicle body. The force transmission structure of the vehicle body comprises a front anti-collision beam, afront longitudinal beam, a first connecting part, a dash panel cross beam, a middle channel, a second connecting part, a footrest, a torsion box, an A column inner plate and a threshold. The front anti-collision beam, the front longitudinal beam, the first connecting part, the dash panel cross beam and the middle channel can conduct force transmission and are matched to form a first force transmission path, and the front anti-collision beam, the front longitudinal beam, the second connecting part, the footrest, the torsion box, the A column inner plate and the threshold can conduct force transmission and are matched to form a second force transmission path. According to the vehicle, the vehicle body and the force transmission structure of the vehicle body, compared with a traditional force transmission structure with a single transmission path, structural failure caused by the single transmission path can be avoided, collision force can be dispersed, stress concentration is avoided, damage to the vehicle body structure of a passenger compartment part in the collision force transmission process is avoided, and the passenger safety is guaranteed.
本发明涉及一种车辆、车身及其力传递结构,车身的力传递结构包括前防撞梁、前纵梁、第一连接部、前围板横梁、中通道、第二连接部、歇脚板、扭力盒、A柱内板及门槛;其中,前防撞梁、前纵梁、第一连接部、前围板横梁及中通道能够进行力传递并配合形成第一传力路径,前防撞梁、前纵梁、第二连接部、歇脚板、扭力盒、A柱内板及门槛能够进行力传递并配合形成第二传力路径。上述实施例的车辆、车身及其力传递结构,相比路径单一的传统的力传递结构而言,能够避免因传递路径单一引起的结构失效,能够对碰撞力进行分散,避免应力集中,避免碰撞力传递过程中对乘员舱部分的车身结构造成破坏,保证乘员安全。
