As shown in fig. 1 and fig. 2, when a vehicle runs out of control and collides against the buffer assembly 5 between two posts 1, the surface of the vehicle firstly collides with the surface of the supporting rod 504, after the supporting rod 504 is impacted, the telescopic rod 503 and the second sleeve 502 are simultaneously driven to rotate around the axis of the lower cross beam 4, because one end of the telescopic rod 503 is hinged with the surface of the first sleeve 501, and the first sleeve 501 is rotationally connected with the upper cross beam 3, the telescopic rod 503 can drive the first sleeve 501 to deflect in the opposite direction of the vehicle impact, the first sleeve 501 can drive the telescopic rod 503 to move along the axial direction and extend out of the supporting rod 504 when deflected, so that the first sleeve 501 can deflect normally, and the first sleeve 501 deflects and simultaneously presses the torsion spring 6 in the first sleeve 501, so that the torsion spring 6 distorts and accumulates potential energy, the impact force generated by the vehicle impact is converted into the elastic potential energy of the torsion spring 6, the impact force generated by the vehicle impact can be effectively slowed down, and the loss caused by the accident can be reduced.
In this embodiment, the circumferential surface of each first sleeve 501 is welded with a connecting rod 7 corresponding to the supporting rod 504; the end of the connecting rod 7 far away from the first sleeve 501 is hinged with a corresponding telescopic rod 503; a spring 8 is arranged between the telescopic rod 503 and the supporting rod 504; the spring 8 is axially arranged inside the support rod 504, one end of the spring 8 is fixedly connected with the surface of the telescopic rod 503, and the other end of the spring is fixedly connected with the support rod 504.
When the automobile collides with the surface of the supporting rod 504 or the connecting rod 7, the supporting rod 504 and the corresponding connecting rod 7 deflect towards the opposite direction of the automobile collision, the connecting rod 7 can drive the telescopic rod 503 to slide out of the supporting rod 504 along the axial direction of the connecting rod 7 while deflecting, at the moment, the connecting rod 7 deflects to drive the first sleeve 501 to squeeze the torsion spring 6 in the telescopic rod 503, and the telescopic rod 503 can also simultaneously pull the spring 8 in the telescopic rod to stretch and prevent the connecting rod 7 and the supporting rod 504 from deflecting further, so that the impact force of the automobile is converted into the elastic potential energy of the spring 8, the impact force generated by the automobile can be further reduced, the spring 8 and the torsion spring 6 are mutually matched, the upper limit of the impact force born by the device can be improved, and the application range of the guard rail is further improved.

When the vehicle is out of control and impacts the surface of the connecting rod 7 or the supporting rod 504, the connecting rod 7 and the supporting rod 504 deflect along the opposite direction of the vehicle impact and absorb the impact force generated by the vehicle, when the supporting rod 504 deflects to the maximum angle, one limiting groove 902 on the inner side surface of the second sleeve 502 is mutually clamped with the limiting block 901, and the second sleeve 502 is fixed at the current position, so that the connecting rod 7 and the supporting rod 504 can not rebound at the current position after absorbing the impact force of the vehicle, and secondary injury to the vehicle and passengers in the vehicle is prevented; on the contrary, when the vehicle impacts the supporting rod 504 or the connecting rod 7 from the other side of the guard rail, the supporting rod 504 deflects towards the opposite direction, so that the other limiting groove 902 on the inner side surface of the second sleeve 502 is mutually clamped with the limiting block 901, and the supporting rod 504 and the connecting rod 7 are prevented from rebounding.
In this embodiment, the outer surfaces of the supporting rod 504 and the connecting rod 7 are both rotatably connected with a rubber buffer sleeve (not shown) coaxially disposed.
The rubber buffer sleeve can further increase the buffer effect of the protective guard to the vehicle, reduces the impact force of the vehicle to the connecting rod 7 and the supporting rod 504 to a certain extent, and the outer surface of the rubber buffer sleeve can be coated with reflective materials or stuck with reflective paper and the like, so that the protective guard can play a striking role on the vehicle running at night.
