Description

A device for absorbing and cushioning the impact of a vehicle collision

technical field

The present invention relates to a device for absorbing and buffering the impact of a vehicle collision, and more particularly to an improved device for effectively absorbing and buffering the impact of a vehicle collision. The cushioning member is constituted by a linear friction preventing member that limits the speed of the rearward movement of the collision head, thereby enabling uniform cushioning effect against collision shock at the time of vehicle collision and controlling the cushioning level according to the estimated vehicle speed. the

Background technique

Traditional devices for absorbing and buffering the impact of vehicles are usually installed on the barriers of highways or underground roads and at the entrance of tunnels to absorb and buffer the impact of vehicles when they collide, which will reduce the damage to drivers. the

Conventional devices for absorbing and cushioning the impact of a vehicle collision include an impact-absorbing base installed on the ground, a fence installed on the upper side of the impact-absorbing base, and a fence installed in the fence and contracted by the impact of the collision when the vehicle collides. An impact-absorbing cushioning member, an impact-absorbing cushioning member installed in the impact-absorbing cushioning member for absorbing collision force, and a collision head installed in a front surface of the impact-absorbing cushioning member. the

The shock absorbing member is installed in the shock absorbing buffer part of the device for absorbing and buffering the shock of the vehicle collision, and the shock buffering member is selectively equipped with a tire (tire) provided in the shock absorbing buffer part or equipped with a plurality of Water container with water. Here, the shock absorbing buffer member is equipped with a collision head provided at the front end and colliding with the vehicle, at least two collision buffer side plates coupled to the rear side of the collision head by bolts and buffering rearward against collision impact, and the collision absorbing side plate provided at the collision absorbing side plate. At least two bumper covers on the upper side. the

Here, slide holes are formed in the front-rear direction of the crash-absorbing side panels, and fastening bolts are installed in the slide holes, so the crash-absorbing side panels frictionally move backward against the crash impact to buffer the crash impact. the

However, conventional devices for absorbing and cushioning the impact of a collision of a vehicle are configured to absorb the impact under the action of frictional force generated when the crash-absorbing side panel moves rearward and the impact-absorbing member is formed of a tire or a water container. To cushion the impact of collisions in components. The cushioning effect is therefore unreliable in terms of impact and it is not easy to design the required system based on an accurate estimate of the impact velocity. Furthermore, it is necessary to obtain a certain accommodation space for substantially accommodating the impact-absorbing member during shrinkage for effectively absorbing impact, which causes many problems during design and construction. the

Contents of the invention

Therefore, it is an object of the present invention to provide a device for absorbing and cushioning the shock of a vehicle collision, which overcomes the impact caused by shock absorbers in conventional devices for absorbing and cushioning the shock of a vehicle collision caused by shock absorbing members such as tires and water. The problem that the container is made so that it cannot reliably absorb the impact of a collision, and that the impact-absorbing member takes up a certain space causes complications in design and installation. the

In the device for absorbing and buffering the impact of a vehicle collision according to the present invention, the impact buffer member capable of buffering the impact of the collision is composed of a linear friction deceleration member that limits the speed at which the collision head of the impact absorbing buffer part moves backward. the

Invention effect

According to the device for absorbing and buffering vehicle collision shock of the present invention, by making the shock absorbing member of the device for absorbing and buffering vehicle collision shock using a linear friction deceleration member, it is easy to effectively control the absorption and buffering force of collision shock. The linear friction deceleration member can limit the speed at which the collision head of the collision impact buffer part moves backward. the
