Embodiment 1

[0024] Such as figure 1 As shown, the present invention shows a buffer device 1, which is especially suitable for use in the front and rear bumpers of automobiles or vehicles. The shock absorber 1 includes a bumper beam 10 which is attached to the vehicle frame 3 through a bumper connector 15 and is relatively movable with respect to the longitudinal direction of the vehicle frame 3 (ie, the longitudinal direction of the vehicle). Of course, this embodiment does not rule out that the bumper bar 3 is also attached to the vehicle frame 3 in other ways at the same time.

[0025] In a typical vehicle, the bumper bar 10 is mounted on the longitudinal beams of the two frames by means of rails 16 ball bearings or similar (not shown) mounted between the frame longitudinal beams and the bumper attachment. out) to realize the longitudinal movement of the bumper bar, which is well known in the automotive field, and will not be repeated here.

[0026] The bumper connector 15 is a hollow...

Embodiment 2

[0033] On the basis of Example 1, such as figure 1 with 2 As shown, there is a groove on the lower side wall of the vehicle frame 3, which is suitable for making the long cantilever 53 of the pendulum 51 pass through the groove, and is attached to the lower side of the vehicle frame 3 through the pin shaft 52 freely rotatable. side wall.

[0034] At the position corresponding to the groove, the lower side wall of the bumper connector 15 is provided with a stopper 41. When the bumper connector 15 moves in the longitudinal direction of the vehicle frame 3, the stopper 41 will come from the bumper bar 10. The impact force of the pendulum is transmitted to the driving end 51 located at the end of the long cantilever 53 of the pendulum 51, so that the pendulum swings against the force of gravity. Since the long cantilever 51 rotates around the pin shaft 52, and the distance between the driving end 51 and the pin shaft 52 is much smaller than the distance from the center of gravit...

Abstract

The invention discloses a buffering device which comprises a bumper transverse bar (10).The bumper transverse bar (10) is attached to a vehicle frame (3) through a bumper connecting piece (15), permanent magnets (131) are arranged in an end plate (21) and a transverse partition board (13), and the magnetic pole of the permanent magnet in the end plate (21) and the magnetic pole of the permanent magnet in the transverse partition board (13) are opposite.The bumper transverse bar can sensitively respond and deform even under small impact force, pedestrians can be well protected in the low-speed state, and small deformation can automatically restore.

Description

technical field [0001] The invention relates to a buffer device, in particular to a buffer device using a permanent magnet for a vehicle bumper. Background technique [0002] Generally, bumpers are arranged on automobiles or other vehicles, so that when the automobile collides with automobiles or other obstacles, the bumpers arranged at the front and rear of the automobile absorb and buffer the external impact force and protect the front and rear of the vehicle body. Reduce injuries to people and vehicles during high-speed collisions. Generally speaking, by setting a buffer material between the bumper and the body, when the bumper is impacted, the impact force is transferred to the body, so that the buffer material is deformed during the interaction between the bumper and the body to achieve Absorbent and cushioning effect. [0003] As disclosed in Chinese patent CN104742838A, a car bumper includes a vehicle body and a bumper mounted on the vehicle body. Relatively inclin...
