As illustrated in FIGS. 1 to 6, the bumper shock absorber 100 for a vehicle according to the present invention is installed at the front or the rear of a freight car or a work vehicle, and a shock absorbing part that cushions a collision with another vehicle or structure. 110 is provided.

At this time, the buffer unit 110 is installed in a plurality at regular intervals in the frame of the front or rear of the vehicle.

Here, the shock absorbing portion 110 is formed in a cylindrical shape is provided with a shock absorbing member 112, the air chamber 114 is formed so that both sides open.

At this time, the buffer member 112 is made of a rubber material having a suitable strength and flexibility, in addition to the material of the buffer member 112 may be used a material having the same or similar properties as the rubber material.

Furthermore, the opposite direction to cover one side of the air chamber 114 of the shock absorbing member 112, the coupling member fixed to the shock absorbing member 112, the binding member 116 is fixed to the frame 102 of the vehicle by fixing means such as bolts ) Is provided.

At this time, a supply hole 118 for supplying air to the air chamber 114 of the buffer member 112 is formed in the central portion of the binding member 116.

In addition, the other side of the shock absorbing member 112, that is, the fixing member 120 is provided to cover the opposite direction of the shock absorbing member 112 to which the binding member 116 is fixed.

In addition, the frame portion 210 is installed in the opposite direction coupled to the frame 102 of the vehicle, and the bumper 104 is fixedly coupled to the outer portion.

Here, the frame part 210 is fixed to the fixing member 120 of the buffer unit 110 by a fixing means such as a bolt, and the bumper 104 is fixed by the fixing means in the opposite direction in which the fixing member 120 is fixed. The frame member 212 to be mounted is provided.

In addition, the guide portion 310 is provided between the frame 102 and the frame member 212 of the vehicle body to guide the operation of the frame member 212 during the buffering action.

Here, the guide portion 310 is provided with a guide tube 312 is fixed to the frame 102 of the vehicle body, the guide member 314 is fitted to be guided to the guide tube 312 is provided.

In this case, one side of the guide member 314 is fixed to the frame member 212 by fixing means such as bolts, and a plurality of binding holes 314a are formed at predetermined intervals in opposite directions fixed to the frame member 212. .

Further, the guide pin 318 is inserted into the guide member 314, positioned in the rear portion of the guide tube 312, and a through hole 316a corresponding to the binding hole 314a of the guide member 314 is formed and the fixing pin 318 Fixing ring 316 is fixed to the guide member 314 by the).

Therefore, the binding hole 314a and the through hole 316a coincide with any one of the plurality of binding holes 314a formed in the guide member 314, and then penetrate the binding hole 314a with the fixing pin 318. By penetrating and fixing the ball 316a, the guide member 314 is prevented from being separated from the guide tube 312, and at the same time, the distance between the frame 102 and the bumper 104 of the vehicle can be easily adjusted. do.

In addition, an air supply unit 410 for generating and supplying air to the air chamber 114 formed in the buffer member 112 of the buffer unit 110 is provided.

Here, the air supply unit 410 is provided with a compressor 412 for generating air, one side is fixed to the compressor 412, the other side supply hole formed in the binding member 116 of the buffer unit 110 ( 118 is provided with an air supply pipe 414 coupled and fixed, the air supply pipe 414 is provided with a pressure gauge 416.

At this time, while controlling the operation of the compressor 412, a switch 424 connected to the battery of the vehicle is provided.

Further, the air supply pipe 414 is provided with an air supply valve 418 to open when supplying air, the air discharge valve to open when discharging the air injected into the air chamber 114 of the buffer member 112 ( 420 is provided, and a check valve 422 is provided in the air supply pipe 414 between the compressor 412 and the air supply valve 418.

Accordingly, while supplying air to the air chamber 114 of the buffer member 112, the air discharge valve 420 may be opened as necessary to discharge air from the air chamber 114, and the pressure gauge 416 Through checking the air pressure of the air chamber 114 from time to time it is possible to adjust the air pressure.

Referring to the operation relationship for the bumper shock absorber for a vehicle according to the invention configured as described above are as follows.

7 is a view showing the working relationship of the bumper shock absorber for a vehicle according to the invention.

As shown in the bumper shock absorber 100 for a vehicle 100 according to the present invention, first, when the switch 424 is turned on from OFF, the compressor 412 operates while generating air.

In this state, when the air supply valve 418 is opened and the air discharge valve 420 is closed, the air generated by the compressor 412 is transferred to the air chamber 114 of the buffer member 112 through the air supply pipe 414. Air will be charged.

As such, after air is charged in the air chamber 114 of the buffer member 112, the air supply valve 418 is closed to maintain the air filled state.

As such, after the air is charged to the air chamber 114 of the shock absorbing member 112, the driver may not drive the vehicle while driving slowly or parked in order to perform maintenance work such as facility on the road using a work vehicle. When a collision occurs due to the collision of the vehicle at the shock absorbing member 112, the impact is absorbed at the same time.

At this time, the shock absorbing member 112 is pushed in the direction of the vehicle body when the shock is absorbed. In this case, the guide member 314 slides on the guide tube 312 so that the shock absorbing member 112 and the bumper 104 are separated. Absorbs the shock and returns to normal.

Accordingly, by mitigating the impact caused by the collision of the vehicle in the shock absorbing member 112, it is possible to minimize the damage of the work vehicle and the counterpart vehicle, and to prevent the occurrence of large-scale accidents such as human injury Will be.

Thus, by installing the buffer unit 110 in the front or rear of the work vehicle, it is possible to perform a safe operation.

On the other hand, the user can smoothly adjust the bumper 104 protruding from the vehicle body can be easily adjusted to fit the type and size of the vehicle.

That is, when the gap between the vehicle body and the bumper 104 is to be widened, the fixing pin 318 inserted into the through hole 316a of the fixing ring 316 and the binding hole 314a of the guide member 314 is separated and After sliding the guide member 314 from the guide tube 312 and fixing the fixing pin 318 through the through hole 316a and the binding hole 314a, the user's desired body and bumper 104 The gap can be easily adjusted.

In addition, the bumper shock absorber 100 for a vehicle according to the present invention is not limited to a work vehicle, and the same effect can be obtained even when applied to a large vehicle such as a van and a van.

8 is a view showing another embodiment of a bumper shock absorber for a vehicle according to the present invention.

As shown therein is provided with an elastic member 320 to be fitted to the guide member 314, the elastic member 320 is installed between the guide tube 312 and the frame member 212.

The working relationship for the bumper shock absorber for automobile according to the present invention configured as described above is made by the same method as in the former, and the description of the working relationship will be omitted here.

However, by installing the elastic member 320 in the guide member 314, the shock absorbing member 112 in the vehicle bumps (shock) and the shock at the same time the guide member 314 slides on the guide tube 312 While being moved to cushion the impact by the elastic member 320 it is possible to more effectively mitigate the impact.

Therefore, by the shock absorbing member 112 and the elastic member 320 in the event of a collision of the vehicle, it is possible to prevent the occurrence of large traffic accidents such as human injury.

In the above, a preferred embodiment of the bumper shock absorber for an automobile according to the present invention has been described, but the present invention is not limited thereto, and various modifications are made within the scope of the claims and the detailed description of the invention and the accompanying drawings. It is possible to implement, which also belongs to the scope of the present invention.
