[0001] APPARATUS FOR COLLISION RELAXATION OF VEHICLES [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle collision shock absorber provided at an end of a separator provided on a road and capable of relieving an impact when a driver collides with a separator without being able to find it, A front support member and an intermediate support member. The impact absorbing member is disposed between the front support member, the intermediate support member, and the plurality of intermediate support members to gradually reduce the impact from the front, And more particularly to a vehicle crash shock absorber capable of gradually absorbing an impact by deforming an impact absorbing member by constituting a plurality of absorbing holes in the shock absorbing member.

Generally, most of the roads including highways have concrete structures such as intersection entrance roads, tunnels, and bridge piers. When a vehicle collides with such a structure, there are many cases in which damage to property and human life are also caused.

Conventionally, various types of structures have been used in which luggage tires are laminated or installed in order to cushion shocks when a vehicle collides,

Such a conventional technique is disclosed in Korean Utility Model Registration No. 20-0401522 entitled " Vehicle Collision Mitigation Device Installation Structure for Road Tunnel Entrance "

The above-mentioned prior art is formed in a curved shape gently from the outside of the tunnel toward the entrance, and has a plurality of projections and flattened ribs on the front and rear surfaces, respectively, and a plurality of slide slots, A urethane layer formed on the front surface of the anti-vehicular anti-reflection beam, a non-anti-deviation beam, which is vertically fixed to the ground and slidably engaged with the slide slot formed in the anti-deviation beam to guide the anti-deviation beam in the left- And a buffer block interposed between the parallel ribs and the guide posts formed on the rear surface of the anti-tamper-resistant beam and having rib-engaging portions and post-fitting grooves on the front and rear surfaces, respectively, .

However, the above-mentioned prior art simplifies the impact through the buffer block of the buffer material, and when the buffer block is applied at a high speed and a large impact, the impact can not be absorbed only by the buffer block.

Also, according to the prior art, there is a registration clerk 20-0271364 entitled " Vehicle collision damping device at an intersection entrance road "

In the prior art, two center supporting beams and two succeeding supporting columns are arranged in a row on the basis of the approach direction of the vehicle, respectively, and the upper and lower supporting pillars A front tire fastening band coupled to the front ends of the upper and lower guide bars respectively inserted into the guide holes and a plurality of side tire fasteners extending rearward of the front tire fastening bases are symmetrically deployed And the bearing connecting rods are connected in series to the upper and lower ends of the respective bearings so that the front and side tire fastening rods are rotatably connected to each other to form a triangle.

However, in the prior art, the first shock is relieved by using the tire, and the guide bar is secondarily impacted as the guide bar penetrates through the guide hole. In case of strong impact, the guide bar is easily broken, There is a problem that the vehicle is repelled by the elasticity of the tire due to the use of the tire, so that a larger accident may occur.

As another prior art, there is a "Vehicle Collision Mitigation Device for Road Tunnel Entrance" of Registration No. 10-0592186,

The above-mentioned prior art has a plate chain support frame which is located on the front side of a concrete brace installed at a road tunnel entrance and has a horizontal surface and a vertical surface fixed by anchor bolts to the ground and a concrete brace, And a front side is located on the inner side of the rear side of the front side of the front tie and is joined on the long side by the fastening bolt and a plurality of long holes are formed on the rear side of the front side tie, A plate chain connecting fitting having a plurality of elongated holes formed on a front side and a rear side, the front elongated hole being engaged with a slot and a fastening bolt of the rear fitting; And a plurality of long holes are formed on the front side of the plate body, And an arcuate folded portion fixed to a vertical surface of the support frame and having an arch portion of the arcuate folding attachment placed on the inner side thereof.

However, in the above-mentioned prior art, when an impact occurs, the multi-step joints are sequentially connected and the rear portion is folded to absorb the impact. In the case where an impact is generated, there is a possibility that the rear portion is not bent, There is a problem that a secondary accident may occur because the debris can be directed to the vehicle again.

Before describing the present invention, the portion where the vehicle collides (the front support bar direction) is referred to as the front end or the front end, and the opposite direction (rear support bar direction) is referred to as the rear end or the rear end.

The vehicle collision damping device A according to the present invention includes a rail 10 provided on a mounting surface and a front support 20, a rear support 30 and an intermediate support 40 provided on the rail 10 The shock absorbing member 50 is provided with a slot between the support rods (the front support rods 20, the middle support rods 40, and the rear support rods 30) So that it is possible to reduce the size of an accident by absorbing the impact of a vehicle collision.

1 to 3, the present invention is characterized in that a rail 10 fixedly installed on a mounting surface of a road or the like is provided, A front support frame 20 provided at the front end of the rail 10 and a rear support frame 30 provided at the rear end of the rail 10 are arranged at the upper portion so that the vehicle directly collides with each other. And is configured to be coupled to the rail 10 so as to be slidable along the rail 10.

In addition, the rail 10 may be composed of two pairs or a single rail, which may be variously changed depending on the installation environment and circumstances, and the scope of the right should not be limited.

Further, the rail 10 is firmly fixed to the floor through fixing means such as an anchor bolt, so that even if an impact is applied to the vehicle collision damping device A according to the present invention, the rail 10 is installed so as to be firmly fixed to the floor .

A plurality of, preferably three or four, sliding panels 11 connecting the front support 20, the plurality of intermediate supports 40, and the rear support 30 are provided on both sides of the front panel.

More specifically, the operation of the vehicle collision damping apparatus A according to the present invention will be described. When the running vehicle impacts the front support 20, the front support 20 moves along the rail 10 to the rear support 30, And the intermediate supports 40 are gradually pushed together by the rear support 30 to absorb the impact.

Therefore, it is preferable that the rear support member 30 is fixed to the rail 10, and a reinforcing support member may be further provided at the rear end of the rear support member 30, and the scope of the right should not be limited.

In addition, it is preferable that a round cover R is further provided at the front end of the front support frame 20 so as to absorb the impact in the event of a vehicle collision, and the round cover R and the front support frame 20 may be provided with a separate shock absorbing member capable of absorbing the shock, and the scope of the right should not be limited.

The front support base 20 and the intermediate support base 40 have the same shape and constitute the slider 41 at the lower end so as to be able to be bound to the rail 10.

More specifically, the slider 41 preferably includes a structure for wrapping the rail 10 so that the slider 41 can slide along the rail 10 while binding the rail 10, And may be formed in a different shape depending on the shape of the rail 10 and may be any structure as long as it can move along the rail 10 without being separated from the rail 10.

Further, in the present invention, the number of the intermediate supports 40 provided between the front support 20 and the rear support 30 is four for convenience of explanation, It should not be construed to limit the scope of rights.

The space between the front support 20 and the best intermediate support 40 is referred to as a first space 50A and the rear support 30 and the rear intermediate support 40 The space between them will be referred to as the second to fourth space portions 50B, 50C and 50D sequentially from the front end to the rear end, If the number of supports 40 is changed, this also can be changed, and the scope of the right should not be limited.

again. The present invention is intended to reduce the damage caused by a collision of a vehicle in a gradual manner by reducing the impact of the accident. As described above, when the front support 20 and the rear support 30 are pushed along the rail 10 There is a limit to the method.

Accordingly, in order to gradually reduce the impact, the present invention is characterized in that a plurality of holes 13 are formed in the sliding panel 11 as shown in FIG. 4, and bolts 15 ).

More specifically, the sliding panel 11 covers the side surface between the front support 20 and the rear support 30. The sliding panel 11 includes a first space 50A, The rear end of the front sliding panel 11 is provided at the front end of the rear sliding panel 11, As shown in FIG.

Therefore, when an impact occurs due to a collision of the vehicle, the front support 20 is pushed back along the rail 10, and at this time, the sliding panel 11 fixed to the front support 20 is supported by the front support 20 And is superimposed on the sliding panel 11 of the intermediate support 40 at the tip of the intermediate support 40 while being pushed together. When the impact load is large, the front support rods 20 are pushed to the intermediate support rods 40 at the front end, and the shock absorbers are absorbed by being superimposed on the sliding panels 11 of the intermediate support rods 40 located behind the front support rods 40.

In this case, the bolt 15 moves along the hole 13, and by absorbing a part of the impact by the friction, the impact is relieved. More preferably, the hole 13 has a plurality of holes 13 It is preferable that the bolts 15 are cut so as to pass through the cut-off portions so as to absorb impact more effectively.

Again, the present invention further includes a shock absorbing member 50, as shown in Figures 3 and 5, to further cushion the impact of the vehicle.

The figure shows a configuration in which the shock absorber 50 is provided so as to connect the front and rear supports to the first to fifth space portions 50A, 50B, 50C, 50D, 50E, The impact absorbing member 50 may have a shape connecting the front support rods 20 and the rear support rods 30 and penetrating the plurality of intermediate support rods 40 positioned therebetween. Can not be done.

The shock absorbing member 50 may be made of a tubular pipe having a through hole 53 formed therein. In order to more effectively absorb impact, the through hole 53 may be filled with a buffer member.

The shock absorber 50 is disposed between each support, that is, between the front support 20 and the intermediate support 40, between the plurality of intermediate supports 40, And one or more absorbing holes 51 may be formed in the center of the impact absorbing member 50. The absorbing member 50 may be provided between the supporting member 40 and the rear supporting member 30,

Therefore, when an impact is applied to the impact absorbing member 50, the strength of the expanding portion 55 formed with the absorbing hole 51 is greater than the strength of the front portion of one shock absorbing member 50 in which the absorbing hole 51 is not formed So that it is deformed into a shape that swells so that the diameter of the expanding portion 55 becomes larger as shown in the drawing.

As a result, the impact applied by the deformation is reduced, and the shock absorbing member 50 is provided on each of the first to fifth space portions to reduce the impact applied to the front support 20 .

Furthermore, when a strong impact is generated, there arises a problem that the shock absorbing member 50 at the rearmost end can be damaged before the impact absorbing member 50 at the end,

In order to solve this problem, the present invention is configured to differentiate the size or the number of the absorbing holes 51 or both of them in order to increase the strength from the front support 20 to the rear support 30.

That is, when the size of the absorption hole 51 is increased, the strength is weakened. When the number of the absorption holes 51 is increased, the strength is weakened. Absorbing member 50 provided at the rear end is made stronger than the impact-absorbing member 50 provided at the front end by decreasing the number of the absorbing holes 51 provided at the front end, To be deformed.

Of course, it is also possible to solve this problem by making the number of the absorption holes 51 the same and varying the size thereof, and the scope of the right should not be limited.

In addition, by such a configuration, since the deformation gradually occurs from the front end of the vehicle collision damping device A according to the present invention by the impact, it is possible to replace-repair only the deformation occurred portion, do.

6, the shape of the absorption hole 51 may be formed in a spiral shape on the outer surface of the shock absorbing member 50, or may be formed of a plurality of spaced apart holes,

It is possible to deform into various shapes in which the strength of the tip end and the rear end is made stronger than the strength of the intermediate portion with respect to the single shock absorbing member 50.

As shown in FIG. 8, the number of the shock absorbing members 50 may be varied to increase the strength of the rear support member 30 toward the rear support member 30. FIG. 8 illustrates one embodiment, And should not be construed as limiting the scope of its rights.

7 again shows another modification of the vehicle collision damping device A according to the present invention,

Absorbing member 50 is deformed in one direction without being unfolded evenly in four directions and is damaged when the impact is applied.

That is, an expansion guide member 57 is further provided inside the through hole 53 of the shock absorbing member 50, that is, in the expanding portion 55 to increase the diameter of the expanding portion 55 a little, So as to be deformed in a direction in which the diameter increases evenly,

Fig. 7 shows a process of inserting such an expansion inducing member 57. Fig.

More specifically, the expansion guide member 57 is made of a material such as urethane or silicone. The expansion guide member 57 has a diameter smaller than the diameter of the impact absorbing member 50, Absorbing member 50 at the same time by inserting the pressure cylinder C at both sides of the impact absorbing member 50 to press both sides of the inflation guiding member 57. By this pressing force, The member 57 is deformed flatly to push the bulging portion 55 of the impact absorbing member 50 having a weak strength from the inside to the outside to keep the diameter slightly larger.

That is, when viewed from the side view, the impact absorbing member 50 has a curved shape so that the middle portion protrudes in a convex shape. Accordingly, when the impact is generated, the curved expanding portion 55 is deformed It is possible to maximize the effect of absorbing the aforementioned shock.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Changes and substitutions are to be construed as falling within the scope of protection of the present invention.
