At this time, the support body portion 162 can linearly move together with the third guide portion 161. Particularly, as the first supporting part 160 moves, the center of the first supporting part 160 can coincide with the center of the second supporting part 122.

Therefore, the vehicle outrigger device 100 can easily implement the movement of the first supporting part 160 through the linear movement of the length varying part 120. [ The vehicle outrigger device 100 moves the first body part C to the first body part C in a state where the first body part C is covered by the maximum extent of the bottom surface of the body C, It is possible to reduce safety accidents or traffic accidents that may occur due to collision of the first pedestal part 160 with an external object when the vehicle body C is operated.

FIG. 7 is an operation diagram showing a third operation state of the vehicle outrigger device shown in FIG. 1. FIG. 8 is a conceptual diagram showing the vehicle outrigger device shown in FIG.

Referring to FIGS. 7 and 8, while the length variable portion 120 is continuously moving, the first support portion 160 can linearly move a certain distance through the above-described movement. The linear movement of the first support portion 160 may not occur any longer when the length of the variable length portion 120 is equal to or greater than a predetermined distance.

The elastic portion 173 is restored to an initial length in a compressed state and the actuating portion 172 is exposed to the outside of the first sliding portion 140 by a predetermined distance Can be maintained. In this case, the connection portion 171 does not move, and one end of the second guide portion 180 can maintain contact with one end of the connection portion 171. At this time, the position of the first supporting part 160 can be fixed, and the center of the first supporting part 160 and the center of the second supporting part 122 can coincide with each other.

The length variable portion 120 may be continuously increased in length. At this time, if the length of the variable length portion 120 is equal to or greater than a predetermined distance, the first support portion 160 may contact the ground. The vehicle body C can be spaced apart from the ground surface by a predetermined distance and the length variable portion 120, the first pedestal portion 160, and the second pedestal portion 122 So that force can be applied to the ground.

Meanwhile, it is also possible to provide the elastic member 163 in accordance with the shape of the ground during the above-described operation. For example, when the ground surface is soft or has a soft ground such as sand, the elastic member 163 may be worn on the first support portion 160 or installed under the first support portion 160 as described above have. On the other hand, in the case of a non-soft ground, it is also possible to use the first support portion 160 directly by contacting the ground without directly installing the elastic member 163.

When the ground surface is inclined or the ground surface is uneven, the cylinders of the second pedestal portion 122 and the length-variable portion 120 are pivotally connected to each other so that the second pedestal portion 122 and the cylinder of the length- It is also possible to form a constant angle. At this time, the alignment unit 193 can prevent the length variable unit 120 from being disposed excessively inclined with respect to the second support unit 122. [ The alignment unit 193 is formed in a cylindrical shape as described above, so that the path or position of the cylinder of the length varying unit 120 can be limited by the diameter of a certain cylinder.

In this case, the bracket 150 and the first supporting part 160 are separated from each other and not connected to each other. Therefore, even if the bracket 150 moves together with the length varying part 120, May not be limited by the first receiving unit 160. [

On the other hand, the vehicle outrigger device 100 may be performed after the use of the vehicle is completed. For example, when the length of the length-variable portion 120 is small, the first support portion 160 pushes the bracket 150 upward (or in the + Z direction) while moving together with the second support portion 122 You can raise. At this time, the first sliding part 140 may enter into the first guide part 130.

When the first sliding part 140 enters the first guide part 130 and is inserted into the first guide part 130 for a predetermined distance or more, the end of the operating part 172 contacts the first guide part 130 . When the length of the variable length portion 120 is continuously reduced, the first guide portion 130 can apply force to the actuating portion 172, and the actuating portion 172 moves to the inside of the first sliding portion 140 The elastic portion 173 can be compressed according to the motion of the actuating portion 172. The elastic portion 173 can be moved in the direction of -Z. The distance separating portion 174 can guide the movement of the operating portion 172. [

The connection wire 171b and the connection bar 171a can be pushed together with the operation part 172 in accordance with the movement of the operation part 172. [ At this time, the movement of the connecting wire 171b and the connecting bar 171a is performed in a direction in which the first receiving part 160 connected to the connecting bar 171a is moved away from the second receiving part 122 7 + X direction).

When the connecting wire 171b and the connecting bar 171a are moved as described above, the second receiving portion 122 and the first receiving portion 160 may be positioned at the same position as that of FIG. At this time, the center of the second bearing portion 122 and the center of the first bearing portion 160 may be different from each other.

A portion of the length variable portion 120 and the alignment portion 193 may contact each other to fix the position of the bracket 150. When the length of the first flexible portion 120 is adjusted, The position can also be fixed.

Thereafter, the linear driving part 192 is operated to insert the supporting part 110 into the body C of the vehicle. At this time, most of the first support portion 160 can be disposed on the lower surface of the vehicle body C. [

Therefore, the vehicle outrigger device 100 can secure a sufficient supporting force even in the soft ground by using the first receiving portion 160 having a larger area than the second receiving portion 122. In addition, the vehicle outrigger device 100 can safely support the vehicle body C even on a sloping ground. Since the vehicle outrigger device 100 can be used through a simple operation, the user's convenience can be increased.

The shape of each component described above can be implemented in various shapes only in one embodiment. For example, in the above description, each component is described mainly in the case of a circular or cylindrical shape, but may also include a polygonal or polygonal shape. The embodiments of the present invention are not limited to the above embodiments and may include all matters obvious to those skilled in the art.
