The invention relates to the technical field of vehicle collision energy absorption, in particular to a collision energy absorption structure and a vehicle. The collision energy absorption structure comprises a front auxiliary frame, a longitudinal beam and an upper edge beam, the roof side rail comprises a first connecting part and a second connecting part, and the first connecting part and the second connecting part are connected with the front auxiliary frame and the longitudinal beam respectively; a first collision part extending in the width direction of the vehicle body is arranged at the end, located on the vehicle head, of the longitudinal beam, and the first collision part and at least part of the upper edge beam are overlapped in the width direction of the vehicle body. According to the collision energy absorption structure, through the arrangement of the first connecting part and the second connecting part, it is guaranteed that the roof side rail can be reliably connected with the front auxiliary frame and the longitudinal beam, when the roof side rail is collided, it can be guaranteed that redundant arrangement is formed at the connecting point position of the roof side rail, and the reliability of a vehicle body and the safety of a vehicle are improved; the first collision portion directly collides with the barrier together with the roof side rail in a collision test.

    本公开涉及车辆碰撞吸能技术领域,尤其涉及一种碰撞吸能结构以及车辆。该碰撞吸能结构包括:前副车架、纵梁和上边梁;所述上边梁包括第一连接部和第二连接部,所述第一连接部和所述第二连接部分别与所述前副车架和所述纵梁连接;所述纵梁位于车头的端部设有沿车身宽度方向延伸的第一碰撞部,所述第一碰撞部与至少部分所述上边梁在车身宽度方向上重叠。该碰撞吸能结构,通过第一连接部和第二连接部的设置,保证上边梁能够与前副车架和纵梁实现可靠的连接,当上边梁受到撞击时,能够保证上边梁在此处的连接点位形成冗余设置,提高车身的可靠性和车辆的安全性;第一碰撞部在碰撞试验中与上边梁一同与壁障发生正碰。
