Some groups of magnet are equipped with rear side of piston, the auxiliary damping cylinder bottom is also provided with some groups of magnet, when bearing plate is hit
When hitting, the auxiliary support bar of both sides is moved rearwards, so as to drive first piston to move down, due to the magnet on first piston with
Aid in the magnet polarities of damping cylinder bottom identical so that according to the principle that identical charges repel each other, first piston be subject to one it is upward
Active force, so as to play the role of bumper and absorbing shock.
The bearing plate back center position is also welded with main support rod, and center is also welded with main subtract on front side of support plate
Cylinder is shaken, main support rod pierces into main damping cylinder interior and is fixedly connected with second piston, second piston rear side and main damping gas
Some groups of damping springs are fixedly connected between cylinder bottom portion, being provided with some groups at left and right sides of the main damping cylinder the latter half changes
Stomata, when bearing plate is impacted, while drives main support rod side movement backward, main support rod drives second piston to rear side
It is mobile, due to the effect of damping spring, so as to play the role of damping, buffering, moved after second piston by the air in lower cavity
Gradually discharged from air vent, simultaneously because gradually can be blocked air vent when being moved after second piston, ventilation hole number is increasingly
It is few so that the speed of exhaust is slower and slower so that second piston decline it is slower and slower so that effectively avoid damping spring by
To impact it is too fast permanent infringement is caused to damping spring, while when being sprung back after shock, due to the negligible amounts of air vent,
Beginning rebound velocity is relatively slow and gradually accelerates, so as to accomplish slowly to spring back, improves stability of automobile；It is also solid on rear side of the support plate
Dingan County is equipped with limit protective device, and limit protective device is internally provided with buffer air bag, when automobile is subject to enormous impact, support plate
Start to deform, so that buffer air bag is extruded, using buffer air bag again into row buffering, so as to effectively reduce fuselage damage journey
Degree.
As further program of the utility model：Mounting base is welded with rear side of the support plate, spiral shell is tapped with mounting base
Line mounting hole.
As the utility model further scheme：The bearing plate is alloy-steel plate.
As the utility model further scheme：The company of slip between the auxiliary support bar and auxiliary damping cylinder
Connect.
As the utility model further scheme：Magnet and auxiliary damping cylinder bottom on rear side of the first piston
Magnet positions it is opposite and polarity is identical.
Compared with prior art, the beneficial effects of the utility model are：Two groups of damping devices are set in the collision prevention girders
Buffering effect can be effectively improved, vehicle body when hitting is reduced and loses.
Moved when being hit after second piston and gradually discharge the air in lower cavity from air vent, simultaneously because
Gradually air vent can be blocked when being moved after second piston, ventilation hole number is fewer and fewer, so that the speed of exhaust is slower and slower,
Second piston decline it is slower and slower so that effectively avoiding damping spring from being impacted too fast causes damping spring permanent damage
When doing harm to, while being sprung back after shock, due to the negligible amounts of air vent, beginning rebound velocity is relatively slow and gradually accelerates, so as to do
To slow rebound, stability of automobile is improved.
