The power of interior many places works to protection post 21, can greatly reduce the inclined angle of protection post 21, both effectively reduce automobile
Impact force；
The buffering of power when being collided with protective plate 34: when automobile and protective plate 34 collide, car crass to crash bar
37, and crash bar 37 can rotate, and can decompose the impact force of a part, then, anticollision spring 353 and 32 work of limit spring
To make, impact force is transmitted to anticollision spring 353 by crash bar 37, then is transmitted to limit spring 32 by protective plate 34, so as to
Impact force is enough effectively reduced, meanwhile, impact force is transmitted on buffering branch 36 by crash bar 37 and anticollision support rod 351, is made
The work of branch 36 must be buffered；
The reaction of power when colliding with protective plate 34: the impact force after decomposition drives sealing-plug by anticollision support rod 351
361 move backward, and the air in protective plate 34 is entered in inflator 38 by gas-guide tube 362, and drives cushion plugs 381 to Forward
Dynamic, cushion plugs 381 drive buffer board 383 to move forward by buffer bar 382, so that buffer board 383 is from the middle part of crash bar 37
It is contacted across with automobile, to realize impact force by reacting on automobile using conversion, effectively reduces automobile and shield
Impact force when column collides；
Multiple 3 cooperatings of protective device: three protective plates 34 are connected by tracheae 4, can either be cooperated, will be touched
Force reaction is hit in automobile, and 3 swelling fracture of protective device can be prevented.
Workflow in summary realizes the function that automobile Yu guardrail impact force is effectively reduced, and solves existence conditions
Lower hard guardrail protective action is small, cushion guardail buffering effect is general and hard guardrail and cushion guardail are not subject to impact force
The problems such as changing application, has reached purpose.
The embodiment that the present invention only refers to drawing illustration is illustrated, it is believed that has related fields basic
The personnel of knowledge can carry out the other embodiments of diversified deformation and peer-level based on this.
