In addition, the plurality of spaced apart support 140 may be disposed to be spaced apart from each other in parallel with the closing plate 130 between the front block 120 and the closing plate 130. At this time, the plurality of spaced support 140 is the front block 120 is coupled to the spaced support 140 is located in the most front, the closing plate 130 may be coupled to the spaced support 140 is located at the most rear. have.

On the other hand, the lower end of the support 140 may be provided so that the guide portion 141 protrudes downward to move along the rail (110).

When the rail 110 is formed to protrude upward, the guide part 141 may be formed to surround the rail 110 or may be implemented as wheels that may move along the rail 110, and the rail 110. ) May be formed in a shape corresponding to the shape when the recess is formed concave.

For example, the guide portion 141 is formed in the shape of a rod, as shown in Figure 4, the coupling rod 142 and the coupling rod 142 coupled to the lower end of the separation support 140 and the coupling rod 142 It is formed in a larger than the circumference of the rail 110 may be composed of a locking plate 143 is inserted.

As shown in FIG. 5, the vehicle shock absorber 100 of the road according to the embodiment of the present invention may include a crimping member 190. The pressing member 190 may absorb the impact force that the vehicle impacts the front block 120.

On the other hand, the pressing member 190 is formed to have a rigid in any shape, it may be configured to absorb the shock by being compressed by the impact force.

In one embodiment, the crimping member 190 may be formed in a coil shape, more specifically, in a shape such as a compression coil spring.

Here, the compression coil spring and the pressing member 190 is the same shape and the operation is completely different. For example, the compression coil spring has an elastic force and when the compressive force is applied, the compression coil spring is returned to the initial state when the compressive force is released, while the compressive member 190 has no elastic force, so when the compressive force is applied, the compression coil spring is compressed, even if the compressive force is released It does not return to a state but is maintained in that state.

That is, the pressing member 190 is compressed to absorb the impact force in the form of consuming the impact force of the vehicle as the shape is changed.

On the other hand, the pressing member 190 may be located between the plurality of spaced apart support 140, the pressing member 190, the pressing force toward the direction in which the closing plate 130 is located in the front block 120 It can be configured to be strong.

For example, as in an embodiment, the plurality of pressing members 190 have different pressing forces, and the pressing member 190, which requires an increasingly strong pressing force from the front block 120 to the closing plate 130, is applied to the pressing force. Accordingly, the plurality of spaced apart support 140 may be configured to be inserted in sequence.

Here, the number of the crimping member 190, that is, the number of the plurality of crimping members 190 are arranged in a line in the front, rear with the spaced apart support 140 between, for example, depending on the road conditions, such as the speed limit of the road Accordingly, the number of pressing members 190 can be configured by adding or subtracting the number.

Since the compressive force is configured to become stronger toward the rear of the collision, the vehicle is gradually absorbing a strong impact force when the collision, thereby effectively absorbing the impact of the vehicle can minimize the casualty or damage to road facilities. .

In other words, if a strong compressive force is required in front of the vehicle crash, the vehicle may be largely damaged by the speed at which the vehicle collides, so that the front portion of the vehicle shock absorber 100 is easily compressed, thereby preventing damage to the vehicle and road facilities. It can be minimized.

In addition, when a plurality of the pressing member 190 is arranged up and down of the spaced support 140 may be configured to have a weaker pressing force gradually from the bottom to the top.

That is, the pressing force of the pressing member 190 positioned on the upper portion of the separation support 140 may be weaker than the pressing member 190 positioned below the separating support 140.

Thus, the pressing force of the pressing member 190 positioned at the upper portion is configured to be weaker, so that in the case of a vehicle having a low ground level such as a passenger car, since the impact is first applied to the pressing member 190 positioned at the bottom, the spaced support 140 is inclined. It can be moved along the rail 110 without supporting.

For example, when the pressing force of the pressing member 190 positioned in the upper portion of the spacer support 140 and the pressing member 190 positioned in the bottom is the same, the vehicle having a low ground height is first placed on the pressing member 190 positioned below. When the impact is applied, the impact force transmitted to the crimping member 190 positioned on the upper portion is relatively reduced.

Therefore, the crimping member 190 positioned on the upper side is less compressed than the crimping member 190 positioned on the lower side, so that the upper portion of the spaced support 140 is inclined in the direction in which the vehicle is located so that the movement of the spaced support 140 is smooth. You won't be able to.
