Therefore, the vehicle may absorb the shock generated during the collision of the vehicle including the shock absorbing liquid to protect the vehicle and the passenger.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Example 1

1 is a perspective view showing a shock absorber for a vehicle according to a first embodiment of the present invention, Figure 2 is a cross-sectional view of the line AA 'of FIG.

1 and 2, the vehicle shock absorber includes a case 12 and a shock absorbing liquid 14.

The case 12 includes a material whose shape is deformed by an external force. Preferably, the material of the case 12 includes a metal or a synthetic resin and has a tube shape. More preferably, the material of the case 12 is synthetic rubber having heat resistance. In this case, the case 12 may further include an injection hole 16 for injecting the shock absorbing liquid 14. If the impact is weak, the case 12 is deformed by an external force to absorb the shock and transfer it to the shock absorbing liquid (14). When the impact is strong, the case 12 bursts and spreads the impact and disperses the shock absorbing liquid 14. In this case, the case 12 may have spaces for receiving the plurality of shock absorbing liquids 14 having a plurality of partitions. In addition, the case 12 may have a honeycomb structure.

The shock absorbing liquid 14 is disposed in the case 12. At this time, the shock absorbing solution 14 is disposed in a path through which the shock wave generated by the collision proceeds. Preferably, the shock absorbing liquid 14 includes water, hydrocarbons, gels, or liquefied carbon dioxide. More preferably, the water includes an antifreeze, and the gel includes a polymer gel. When the shock absorbing liquid 14 includes the liquefied carbon dioxide, fire can be prevented.

Thus, the automobile shock absorber includes the shock absorbing liquid 14 to absorb the shock.

Example 2

3 is a perspective view illustrating a bumper according to a second exemplary embodiment of the present invention, and FIG. 4 is a cross-sectional view taken along line BB ′ of FIG. 3. In the present embodiment, since the shock absorbing device for automobiles is the same as that of the first embodiment, duplicated description is omitted.

3 and 4, the bumper includes a plate-like elastic body 22 and an automobile shock absorber 10.

The plate-like elastic body 22 has an elastic material that resists external forces, and has a wider width and a convex portion than a height thereof. An accommodating space for accommodating the automobile shock absorber is disposed at a rear surface corresponding to the central portion of the plate-shaped elastic body.

The vehicle shock absorber includes a case 12 and a shock absorbing liquid 14, and is disposed in a storage space of the plate-like elastic body 22.

Preferably, the plate-like elastic body 22 and the automobile shock absorber 10 are integrally formed.

Therefore, the bumper absorbs the shock generated at the time of front or rear collision including the automobile shock absorber 10.

Example 3

FIG. 5 is a cross-sectional view illustrating a door for a vehicle according to a third exemplary embodiment of the present invention, and FIG. 6 is a cross-sectional view taken along the line CC ′ of FIG. 5. In the present embodiment, since the shock absorbing device for automobiles is the same as that of the first embodiment, duplicated description is omitted.

5 and 6, the automobile door 30 includes a cavity for accommodating the automobile shock absorber 10 therein.

The automobile shock absorber includes a case 12 and a shock absorbing liquid 14 and is disposed in the cavity.

Preferably, the vehicle shock absorber is integrally formed in the vehicle door 30.

Thus, the automobile door 30 includes the automobile shock absorber 10 to absorb the impact during side impact.

The theory is not intended to limit the scope of the present invention, but the present invention will be described using seismic pylons as follows.

When a certain impact is applied to the solid having elasticity, the shock wave generated by the shock is transmitted in the form of P wave, S wave, L wave and the like. The P wave vibrates in the same direction as the traveling direction and passes through all of solid, liquid and gas. The S wave vibrates in a direction perpendicular to the traveling direction and passes through only the solid. The L wave travels along the surface of the elastic body and passes through only the solid.

The impact energy is delivered in an amount several times to several tens of times larger than the P wave through the S wave or L wave.

Therefore, in the case of an automobile made of an elastic body, the shock absorbing liquid may be disposed on a path through which an impact is transmitted to protect the vehicle and the passenger by removing the S wave or the L wave.

In addition, when the amount of impact is large, the shock absorber for the vehicle itself may be ruptured, thereby spreading the impact and encapsulating the automobile and the passenger. Moreover, when the impact absorbing liquid contains liquefied hydrogen dioxide, it is possible to prevent the fire of the vehicle.
