The invention provides a vehicle body frame and a vehicle, and belongs to the field of vehicle body structure design. The vehicle body frame comprises an energy absorption area and a transition area. The energy absorption area comprises a front longitudinal beam and a front longitudinal beam auxiliary beam. The transition area comprises a front doorsill beam, a front door frame column and an A column beam; the front end of the front longitudinal beam auxiliary beam is connected with the rear end of the front longitudinal beam, and the rear end of the front longitudinal beam auxiliary beam is connected with the front doorsill beam. The lower end of the front doorframe column is connected with the front doorsill beam, the upper end of the front doorframe column is connected with the A-column beam, the front end of the front doorsill beam is connected with the A-column beam, and a triangular annular structure is formed by taking three joints as vertexes. According to the vehicle body frame and the vehicle, when the vehicle collides, the front energy absorption area can absorb most collision energy in time, the remaining collision energy can be transmitted to the triangular annular structure of the transition area and then dispersed and transmitted to the vehicle body assembly, and the safety of passengers in the vehicle can be better protected.

    本发明提供了一种车身框架及车辆,属于车身结构设计领域。所述车身框架包括吸能区和过渡区;吸能区包括前纵梁和前纵梁副梁;过渡区包括前门槛梁、前门框柱和A柱梁;前纵梁副梁的前端与前纵梁的后端连接,前纵梁副梁的后端与前门槛梁连接;前门框柱的下端与前门槛梁连接,上端与A柱梁连接,前门槛梁的前端与A柱梁连接,以三个连接处为顶点形成三角形环状结构。本发明提供的车身框架及车辆,车辆在碰撞时前部吸能区能及时吸收大部分碰撞能量,剩余碰撞能量则可传递到过渡区的三角形环状结构,进而分散传递到车身总成,能更好的保护车内乘员的安全。
