The invention belongs to the technical field of automobiles, and relates to a collision protection device and an automobile, the collision protection device comprises a protection beam, a buffer baseand a buffer part, the buffer base is embedded in the protective beam and used for being connected with an automobile body. The buffer part is connected to the side, close to the battery pack, of theprotection beam. By arranging the protection beam, the buffer base and the buffer piece, triple energy absorption and buffer effects are achieved on collision energy generated in the collision process, destructive power during collision is greatly reduced, and the battery pack is effectively protected. When the collision protection device collides with protruding foreign matter on the ground, theprotection beam deforms to absorb a part of energy, first energy absorption is achieved, the buffer base compresses to absorb a part of energy, second energy absorption is achieved, and after the protection beam is bent and deformed, energy generated by collision is absorbed through the buffer piece, third energy absorption is achieved, and third energy absorption is achieved. Through the triple energy absorption, the impact on the battery pack during collision is greatly reduced.

    本发明属于汽车技术领域,涉及一种碰撞保护装置及汽车,包括防护梁、缓冲基座和缓冲件,防护梁为中空结构;缓冲基座嵌于防护梁上,用于连接车身;缓冲件连接于防护梁的靠近电池包的一侧。通过设置防护梁、缓冲基座和缓冲件,对碰撞过程中产生的碰撞能量起到三重吸能和缓冲的作用,极大地减轻了碰撞时的破坏力,有效地保护电池包。当碰撞保护装置与地面凸出异物发生碰撞时,防护梁产生形变吸收一部分能量,实现第一重吸能,缓冲基座发生压缩吸收部分能量,实现第二重吸能,当防护梁发生弯曲变形后,通过缓冲件吸收撞击产生的能量,实现第三重吸能,通过三重吸能,极大地减小了碰撞时对电池包的冲击。
