Problems solved by technology

However, such systems require complex sensors and electromechanical systems to function, and their reliability performance is still questionable
Most importantly, it still does not solve the problem of how to effectively provide protection when the inevitable collision occurs

Embodiment 1

[0026] like 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 buffer device 1 includes a bumper bar 10, the bumper bar 10 is attached to the vehicle frame 3 through a bumper connector 15, and can move relative to the longitudinal direction of the vehicle frame 3 (ie, the longitudinal direction of the vehicle), of course the In the embodiment, it is not excluded that the bumper bar 3 is also attached to the vehicle frame 3 by other means at the same time.

[0027] 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.

[0028] The interior of the first space are...

Embodiment 2

[0034] On the basis of Embodiment 1, a support plate 33 is provided in the end of the vehicle frame 3, and the support plate 33 extends longitudinally along the vehicle frame 3 with a coil spring 22, and the middle part of the buffer frame 3' is provided with a transverse partition 13. 3 is divided into two space areas, the end of the fixed pipe 23 is attached to the diaphragm 13, the fixed pipe 23 is suitable for engaging the coil spring 22, and the other end of the fixed pipe 23 and the buffer frame 3 are open.

[0035] see image 3 , the interior of the diaphragm 13 is provided with a permanent magnet 131, preferably the diaphragm is not made of permanent magnets as a whole, but is composed of small permanent magnets 131 of the same specification in the form of display, and the exterior of the permanent magnet 131 is made of rubber or synthetic The coating of the resin material 132 can effectively prevent the damage of the magnet caused by impact, or the weakening of the ma...

Embodiment 3

[0038] On the basis of Examples 1 and 2, similar to Example 2, such as figure 1 and 2As 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.

[0039] The position of the lower side wall of the buffer frame 3' corresponding to the groove is provided with a stopper 41. When the buffer frame 3' moves in the longitudinal direction of the vehicle frame 3, the stopper 41 will absorb the impact from the bumper bar 10. The force 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 o...

Abstract

The invention discloses a buffer device (1) which comprises a bumper transverse rod (10). The bumper transverse rod (10) is attached onto a vehicle frame (3) by a bumper connecting piece (15) and can longitudinally move relative to the vehicle frame (3). The buffer device is characterized in that the bumper connecting piece (15) comprises a support rod (105) and a pivot plate (107), the support rod (105) longitudinally extends, and the pivot plate (107) is pivotally connected with a buffer frame (3') by a second rotary shaft (106); the pivot plate (107) can rotate relative to the buffer frame (3') within preset angles. The buffer device has the advantages that the bumper transverse rod can sensitively react to deform even under the effect of low impact force, accordingly, excellent pedestrian protection effects can be realized by the buffer device in a low-speed state, and the buffer device with small deformation can be voluntarily restored.

Description

technical field [0001] The present invention relates to a cushioning device, in particular a cushioning device for a vehicle bumper utilizing a pivot plate. 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. Relat...
