{Vehicle's barrier}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a vehicle protection device capable of effectively absorbing impact caused by a collision of a vehicle to prevent a large accident in advance.

Generally, in the case of a vehicle barrier which is installed in various forms such as a guardrail form installed on a median of a road, a roadside, a bridge, etc., it is possible to safely guide the vehicle while the vehicle is running and prevent the vehicle from escaping from the road, Protecting the vehicle.

In the case of such a vehicle protection system, various types of techniques have been developed and utilized as a method for absorbing shocks in the event of a vehicle collision.

Among them, in the case of the "Vehicle Protection Policy" of Korean Patent Laid-Open Publication No. 10-2010-0100568, a buffer member is provided between the rail and the column, and the installation angle of the buffer member is set to be inclined at an angle The collision direction and the installation direction of the cushioning member are mutually coincident with each other or at least at an angle close thereto, thereby improving the buffering effect of the cushioning member. On the other hand, since the installation structure is complicated If the cushion member is installed between the rail and the pillar due to the structural characteristic of the cushioning member, the rail can not be maintained in a stable state even when it is normal. And the problem becomes unstable.

Also known are a "shock absorber" of Korean Patent Laid-Open Publication No. 10-2014-0008649 and a "shock absorber" of Korean Registered Patent Publication No. 10-1448982, The collision energy is gradually reduced as a safety facility to prevent the collision impact from being directly received by colliding directly with the rear equipment at the entrance of the end of the barrier, the underpass, the tunnel, And functions to stop the vehicle safely.

However, this prior art has a disadvantage that it is not suitable to be installed at the tip end of the center separator or the vehicle barrier because the structure is complicated as a whole, the material is large,
