The invention discloses an energy-absorbing bumper of a new energy automobile, which relates to the technical field of bumpers, and adopts the technical scheme that the energy-absorbing bumper comprises an anti-collision beam with two arc-shaped ends; the lever beam is arranged on the rear side of the anti-collision beam, a through groove is formed in the lever beam, first cavities are formed in the two sides of the through groove, and second cavities are formed in the two sides of the first cavities; the device has the beneficial effects that the spring, the first piston, the second piston, the first magnet, the second magnet and other components are designed, the device has a buffering and energy absorbing structure, when the device is impacted, the spring deforms, the distance between the first magnet and the second magnet becomes smaller, and the repulsive force becomes larger and larger; according to the bumper, the buffering and energy absorbing effects can be achieved through deformation of the springs and the action of repulsive force, so that the situation that impact force is completely absorbed by the bumper is avoided, the phenomenon that the bumper deforms under the condition of small impact can be avoided, and high maintenance cost can be avoided.
本发明公开了一种新能源汽车吸能保险杠,涉及保险杠技术领域,其技术方案是:包括:防撞梁,其两端设置为弧状;杠梁,其设置在防撞梁后侧,杠梁内部开设有通槽,通槽两侧均开设有空腔一,空腔一两侧均开设有空腔二;移动杆,其设置为两个,本发明的有益效果是:设计弹簧、活塞一、活塞二、磁铁一和磁铁二等部件本装置就具备了缓冲吸能的结构,在受到撞击的时候弹簧会发生形变,磁铁一和磁铁二之间的距离会变小,排斥力会越来越大,通过弹簧发生形变以及排斥力的作用下就可以起到缓冲吸能的作用,从而避免撞击力全被保险杠自身吸收,进而可以避免在小撞击的情况下保险杠也变形的现象,这样就可以避免出现高昂的维修费用。
