The invention relates to a force transmission structure, an automobile body frame and an automobile. The force transmission structure comprises a front longitudinal beam, a front longitudinal beam rear plate, a front coaming, a front coaming cross beam, an A column inner plate, an inclined support and a doorsill beam, wherein a root of the front longitudinal beam is connected with the front longitudinal beam rear plate; the front coaming is arranged on the front coaming cross beam, and the front coaming cross beam is connected with the front longitudinal beam rear plate; the A column inner plate is connected with the front coaming and the front longitudinal beam rear plate; the inclined support is obliquely arranged on the front coaming, and the two ends of the inclined support are connected with the front longitudinal beam rear plate and the A column inner plate respectively; and the doorsill beam is connected with the front longitudinal beam rear plate. A part of impact force can beeffectively transmitted to the A column inner plate from the root of the front longitudinal beam through the front longitudinal beam rear plate and the inclined support so that a stress burden of thefront longitudinal beam rear plate is reduced, and the front longitudinal beam rear plate is effectively prevented from collapsing and embrittlement. A force transmission characteristic of a vehicle body during collision can be improved, a cracking degree caused by collision is reduced, and structural stability and integrity of the automobile body are improved.
本发明涉及一种传力结构、车身骨架及汽车,该传力结构包括:前纵梁;前纵梁后板,前纵梁的根部与前纵梁后板连接;前围板和前围板横梁,前围板设置于前围板横梁上,前围板横梁与前纵梁后板连接;A柱内板,A柱内板与前围板以及前纵梁后板均连接;斜支撑,斜支撑倾斜设置于前围板上,且斜支撑的两端分别与前纵梁后板以及A柱内板连接;及门槛梁,门槛梁与前纵梁后板连接。一部分撞击力可由前纵梁的根部通过前纵梁后板以及斜支撑有效传递至A柱内板,从而减轻了前纵梁后板的受力负担,有效防止前纵梁后板溃缩脆裂。能够改善车身受碰撞时的传力特性,减轻受撞击发生的溃裂程度,提升车身结构稳定性与完整性。
