Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shock absorber,

The present invention relates to a vehicle shock absorber, and more particularly, to a vehicle shock absorber that absorbs shocks when a traveling vehicle collides with a vehicle disposed to provide a construction vehicle to a traveling vehicle, The present invention relates to a shock absorbing device for a vehicle.

The most difficult task when working to maintain roads is to avoid obstructing the flow of vehicles passing around, and to protect the vehicles and workers passing by. For this reason, maintenance and repair work for roads is often performed at night, when traffic is less frequently, unless it is urgent. However, since there is less flow of traffic at night, it may be more threatening to the safety of workers and drivers.

Because the flow of vehicles is low at night, the speed of the vehicles passing around the construction site is fast, and there is a possibility that unexpected situations such as drowsiness driving and drunken driving may occur, so that the risk of accidents can be increased as much. In order to prevent such problems, the road construction site is equipped with a guide person, a guide plate and a shock absorber.

The shock absorber protects the operator of the construction site by preventing the driver from rushing to the construction facility because he can not recognize the construction facility or the place in advance and absorbs the impact of the impact vehicle to protect the driver.

Fig. 5 shows a general configuration of a shock absorbing device according to the prior art, and is a view included in Korean Patent No. 10-1333210 (hereinafter referred to as "prior art"). The prior art is a view showing a state of use of a shock absorbing structure and a shock absorbing device for allowing a shock absorbing device to absorb a shock to protect a driver and a worker. Referring to the prior art, the shock absorbing device is configured in the form of a box of a hexahedron and is provided with a shock absorbing structure therein.

As shown in FIG. 5, the prior art shock absorbing device having the above structure is provided in front of a sign car, or a vehicle that is provided on the front and rear sides of a construction vehicle, In the event of a collision, it acts to absorb the impact. However, the prior art has many inconveniences in the transportation and installation of the shock absorber. The shock absorber is moved by hanging from the vehicle or the sign vehicle as shown in the figure, and the movable wheels are designed to be relatively small. Therefore, there is no problem moving at a slow speed, but as the speed gets faster, the wheels can be damaged because the smaller wheels can not keep up with the speed. Therefore, there are many cases where the shock absorber is loaded on a separate vehicle, which causes an increase in cost and wasted manpower, thereby increasing the construction cost. Therefore, a means for easily transporting the shock absorber is needed.

Referring to FIG. 1, a vehicle shock absorbing apparatus according to the present invention includes a mounting portion 110 provided on a moving means, a shock absorbing device 100 mounted on one side of the mounting portion 110 so as to be rotatable, And a hydraulic cylinder 150 that serves to load the shock absorber 100 on the mounting portion 110.

The mounting portion 110 serves to load the shock absorber 100 or to mount the hydraulic cylinder 150. The mounting portion 110 may be provided on a rear side of a sign car as shown in FIG. 1 (see FIG. 1), or may be provided in various public vehicles known in the art. A sign vehicle refers to a known device that uses a plurality of light emitting means such as a bulb or the like to make a specific sign (an arrow or the like) at a construction site and notify the construction fact and the traveling direction of the vehicle. The shape and structure of the mounting portion 110 are not particularly limited as long as the mounting portion 100 can be mounted on the mounting portion 100 as will be described later. In an exemplary embodiment of the present invention, an approach detecting sensor (not shown) may be further provided on the upper surface of the mounting portion 110. Thus, when the shock absorber 100 is folded and loaded on the mounting portion 110, it is detected whether the one side of the shock absorber 100 is close to the hydraulic cylinder 150 to control the hydraulic cylinder 150 to be described later. do.

Meanwhile, the vehicle shock absorbing apparatus according to the present invention may further include a lower support member 115 for supporting a lower portion of one side of the shock absorber 100 in the mounting portion 110. Thus, when the shock absorber 100 is fully extended in the horizontal direction, not only the one side of the shock absorber 100 is supported, but also when the vehicle impacts on the shock absorber 100, 123 to prevent the pivotal coupling piece 123 from being broken or damaged. In the preferred embodiment of the present invention, the lower supporter 115 is provided such that a portion of the lower supporter 115 facing one side of the shock absorber 100 is adjacent to the lower surface of the shock absorber 100. A plurality of lower supports 115 may be provided in the horizontal direction (width direction with reference to FIG. 1) of the shock absorber 100. Thus, it is possible to distribute the force applied by the collision of the vehicle from the rear evenly. Further, the lower support table 115 may further include an approach detection sensor for detecting whether the shock absorber 100 is approaching. Thus, when the shock absorber 100 approaches the lower support member 115, it is sensed that the operation of the hydraulic cylinder 150 can be stopped.

The shock absorber 100 is a device for safely stopping the vehicle while absorbing the impact when the vehicle collides. The shock absorbing device 100 is provided with a shock absorbing structure (not shown) therein for reducing the impact. Although the shock absorber 100 is generally constructed in a block shape as shown in the drawing, there are various structures. Further, since the shock absorber 100 is moved or installed by hanging from a sine car or a general construction vehicle, a moving wheel 127 may be provided on the lower surface. The shock absorber 100 having the above-described structure is mounted side by side on one side of the mounting portion 110 so as to be rotatable. Here, one side of the shock absorber 100 refers to a side to which the shock absorber 100 is coupled to the mount 110, and the following expression is used according to the same standard.

The shock absorbing device 100 is hinged to the mounting part 110 with a pivotal coupling piece 123 provided on one side thereof. The pivotal coupling piece 123 is preferably provided adjacent to an upper portion of one side of the stratum absorbing device. When the other side of the shock absorber 100 is vertically erected, the other side of the shock absorber 100 is vertically movable around the pivotal coupling piece 123, The structure becomes a stacked structure.

On the other hand, at one side of the shock absorber 100, a hydraulic engaging piece 125 is further provided below the rotating engaging piece 123. The hydraulic coupling part 125 is hinged to be rotatable with the other end of the hydraulic cylinder 150, which is configured to protrude in one direction of the shock absorber 100 and will be described later. At this time, it is preferable that the hydraulic coupling member 125 is inclined to be adjacent to the pivotal coupling member 123 toward the protruding end. This is for securing a space for installing the hydraulic cylinder 150 and minimizing the lateral load received during the driving of the hydraulic cylinder 150. A method of driving the hydraulic cylinder 150 will be described later.

 One end of the hydraulic cylinder 150 is pivotally coupled to the mount 110 and the other end is pivotally coupled to one side of the shock absorber 100. At this time, the hydraulic cylinder 150 may be provided at a height between the pivotal coupling piece 123 and the hydraulic coupling piece 125 as shown in Figs. 2 and 3, (123).

When the hydraulic cylinder 150 is contracted as described above, the pressure cylinder 150 is vertically supported by the impact absorbing device 100 while the other end of the pressure cylinder 150 sags and is supported in the direction of the hydraulic coupling piece 125 2). When the hydraulic cylinder 150 is expanded, the shock absorber 100 is lifted in a vertical direction as shown in FIG. 3, and the hydraulic cylinder 150 is leveled. If the hydraulic cylinder 150 is fixed in the horizontal direction, the hydraulic cylinder 150 is inflated to lift the shock absorber 100, if the hydraulic cylinder 150 is fixed in the horizontal direction, to prevent or minimize the lateral load of the hydraulic cylinder 150. [ Some of them are subjected to a load in the longitudinal direction but some of them are subjected to a lateral load in the longitudinal direction so that not only the durability of the hydraulic cylinder 150 is lowered but also a large amount of force is required at the initial stage when lifting the shock absorber 100 will be. Accordingly, the hydraulic cylinder 150 is parallel to the hydraulic coupling piece 125, and the hydraulic cylinder 150 is also changed in direction as the shock absorbing device 100 moves, as in the present invention, Thereby facilitating lifting. The reason why one end of the hydraulic cylinder 150 is adjacent to the pivotal engagement piece 123 is that the load applied to the hydraulic cylinder 150 when the shock absorber 100 is lifted by using the hydraulic cylinder 150 This is to keep the direction of the load constant.

In the preferred embodiment of the present invention, an upper support 129 may be further provided on the upper portion of one side of the shock absorber 100. [ The upper support 129 is for supporting the shock absorber 100 in a horizontal direction when the hydraulic cylinder 150 is operated to raise the shock absorber 100. Needless to say, the upper support part 129 may be provided on the upper surface of the mounting part 110 as needed.

4 is a view showing still another embodiment of a vehicle shock absorber according to the present invention.

4, a vehicle shock absorbing device according to the present invention includes a first shock absorbing device 101 whose one side is pivotally coupled to a mount 110, And a second shock absorber 102 rotatably coupled to a lower portion of the other side surface of the shock absorber 101. At this time, a first wheel receiving portion 133 for receiving the moving wheels 127 of the second shock absorbing device 102 is provided on the lower surface of the first shock absorbing device 101, 102 may be provided with a second wheel receiving portion 135 for receiving the moving wheels 127 of the first shock absorbing device 101.

The coupling structure of the first shock absorber 101 and the mounting portion 110 is the same as that described above, and a duplicate description thereof will be omitted. One side surface of the first shock absorbing device 101 and one side surface of the second shock absorbing device 102 are hinged to each other so as to be rotatable. As shown in the drawing, when the first shock absorber 101 is pushed by the hydraulic cylinder 150 and the other is lifted, the second shock absorber 101, which is pivotally coupled with the first shock absorber 101, The first shock absorbing device 101 and the second shock absorbing device 102 are folded and raised while one side of the device 102 is heard. At this time, the moving wheel 127 provided in the first shock absorber 101 is seated on the second wheel housing portion 135 provided in the second shock absorber 102, and the second shock absorber 102 The moving wheels 127 of the first shock absorbing device 101 and the second shock absorbing device 102 are mounted on the first wheel housing part 133 of the first shock absorbing device 101, ) Are brought into close contact with each other as much as possible. At this time, as shown in the drawing, it is preferable that the first shock absorbing device 101 and the driving wheel 127 provided in the second shock absorbing device 102 are provided at positions that do not overlap each other. That is, as shown in the figure, when the driving wheels 127 of the first shock absorbing device 101 are provided adjacent to both ends in the longitudinal direction, the driving wheels 127 of the second shock absorbing device 102 are arranged in the middle When the first shock absorbing device 101 and the second shock absorbing device 102 are folded, the driving wheel 127 and the second shock absorbing device 102 of the first shock absorbing device 101, So that the driving wheels 127 of the drive wheels 127 do not meet at the same position.

As described above, a plurality of shock absorbers 100 are provided to enhance the shock absorbing capability. In general, the performance of the shock absorber 100 is determined depending on the degree of shock absorbing force in a certain standard. That is, it is important to stop the vehicle while minimizing the impact on the impact vehicle at the same length. However, if the required space for installing the shock absorber 100 is sufficient and the performance of the shock absorber 100 provided is somewhat deteriorated, if several shock absorbers 100 are connected at the same time, the shock absorbing capacity will be improved accordingly. However, the larger the size of the shock absorber 100, the more difficult it is to move and install the shock absorber 100. However, it is possible to fold and store and move as in the present invention, and in the case where such a method is easily performed by the hydraulic device, the utilization value will be high.

In the operation of the vehicle shock absorber according to the present invention,

1), when the hydraulic cylinder 150 is completely contracted, the other side of the shock absorber 100 is completely lowered to the bottom and is in a horizontal state, and the hydraulic cylinder (not shown) 150 are inflated, the other side of the shock absorber 100 is lifted up and is vertically mounted on the mounting portion 110. At this time, when the shock absorber 100 is in a substantially vertical direction, that is, when one side of the shock absorber 100 is close to the mount 110 and reaches a desired position, The sensor senses this and stops the driving of the hydraulic cylinder 150. Then, the hydraulic cylinder 150 is fixed while maintaining the expanded state. At this time, if necessary, another fixing means for fixing the vertically erected shock absorber 100 may be further provided.

4) according to another embodiment of the present invention, when the hydraulic cylinder 150 is inflated as described above, the other side of the first shock absorbing device 101 and the second side of the second shock absorbing device 101 One side of the shock absorber 102 is lifted and the first and second shock absorbers 100 are folded and fixed on the mount 110.
