When hitting power across vehicle frame arrival buffer unit, buffer unit passes through bumping post, the first countercheck rod, the second countercheck rod, resistance device
Impact force can be slowed down.The resistance device includes telescopic rod, spring, when resistance device is hit, telescopic rod elongation,
Spring is replied from impaction state, slows down impact force.
First countercheck rod includes connector, barrier plate, and the connector is connect with buffer unit inner wall, connection type
For welding, it is material that barrier plate, which selects alloy spring steel,.Connector is welded on the inner wall of buffer unit, can impacted
When, impact force is integrally exerted a force to buffer unit, to alleviate when being impacted, the power that the first countercheck rod is born.It is described
The contact area of bumping post and buffer unit upper surface junction is less than the contact area of bumping post and buffer unit lower end surface.On
It is in order to when receiving the enormous impact force that bumping post cannot be born, from upper that end face contact area, which is less than lower end surface contact area,
End face is broken, and bumping post is enable to be stuck in the first countercheck rod and the second countercheck rod.The vehicle frame and buffer unit are logical
Threaded connection is crossed, buffer unit rear end is welded on bumper bar skeleton.Threaded connection can allow buffer unit and vehicle frame to be divided
From easy to disassemble.
Compared with prior art, the present invention having the following advantages and benefits:
1, vehicle bumper safeguard structure of the present invention, the first countercheck rod intersect placement with the second countercheck rod, can effectively prevent
Only frontal impact；
2, vehicle bumper safeguard structure of the present invention, is provided with resistance device, can apply opposite force, carries out to impulsive contact force
Buffering；
3, vehicle bumper safeguard structure of the present invention is provided with vehicle frame, buffer unit, bumper skeleton three-decker, energy
Enough effective protection occupants.
