Long rack energy absorption structure

The utility model relates to a long rack energy absorption structure which comprises a long rack, the long rack comprises a tooth-shaped part and an energy absorption part, the tooth-shaped part is meshed with a motor, and the energy absorption part is provided with a weakening structure extending along the length of the energy absorption part so as to deform in the collision process to provide better safety performance. According to the long rack energy absorption structure, the impact force to passengers in the collision process is reduced through deformation of the energy absorption part of the long rack, and therefore the safety performance is improved. 本实用新型涉及一种长齿条吸能结构，包括一长齿条，其中，该长齿条包括齿形部分和吸能部分，其中，齿形部分与电机啮合，吸能部分具有沿其长度延伸的弱化结构以在碰撞过程中发生形变来提供更好的安全性能。根据本实用新型的长齿条吸能结构，通过长齿条的吸能部分的变形来减少碰撞过程中对乘员的冲击力，从而提高安全性能。
