The invention provides a magnetic buffering type anti-collision beam at the front end of an automobile. The anti-collision beam comprises a bow-shaped main beam the back surface of which are provided with connecting clamping bases symmetrically on the left side and the right side, with connecting rotating shafts being arranged in the middles of the connecting clamping bases; a horizontal fixing frame arranged on the rear side of the bow-shaped main beam in parallel; and a telescopic guide rod arranged on the rear side of the connecting clamping bases, a circular sliding block is arranged at the rear end of the telescopic guide rod, and a permanent magnet blocking ring is arranged in the middle of the circular sliding block in a surrounding mode. According to the anti-collision beam, the bow-shaped main beam serves as the collision main beam and is fixed to an automobile through the horizontal fixing frame, the bow-shaped main beam and the horizontal fixing frame are connected through the telescopic guide rod and a telescopic guide cylinder, and the bow-shaped main beam can move towards the rear side to enable the telescopic guide rod and the telescopic guide cylinder to slide relatively when collided, then thepermanent magnet blocking ring is driven to slide in a magnetic resistance inner copper tube, and the telescopic guide rod is hindered through electromagnetic resistance generated by a buffer spring and relative sliding of the buffer spring, so that buffering and energy absorption are carried out.

    本公开提供一种汽车前端磁力缓冲式防撞梁,包括:弓型主梁,所述弓型主梁的背面左右两侧对称设置有连接卡座,所述连接卡座的中间设置有连接转轴;水平固定架,平行设置于所述弓型主梁的后侧;伸缩导向杆,设置于所述连接卡座的后侧,所述伸缩导向杆的后端设置有圆形滑块,所述圆形滑块的中间环绕设置有永磁阻碍环。本发明防撞梁通过弓型主梁作为碰撞主梁,并通过水平固定架固定至汽车上,而弓型主梁与水平固定架之间通过伸缩导向杆和伸缩导向筒连接,受到碰撞时弓型主梁可以向后侧移动使伸缩导向杆和伸缩导向筒相对滑动,进而带动永磁阻碍环在磁阻内铜管中滑动,通过缓冲弹簧和其相对滑动产生的电磁阻力对伸缩导向杆进行阻碍,以进行缓冲吸能。
