[0059] The hydraulic outrigger 24 includes a driving wheel 241 and a hub motor 242; the hydraulic outrigger 24 and the hydraulic cylinder II 23 together form a hydraulic telescopic system. The upper end of the hydraulic outrigger 24 is hydraulically connected to the hydraulic outrigger 24, and the lower end of the hydraulic outrigger 24 is fixedly connected to the driving wheel 241; the hub motor 242 is fixedly arranged inside the driving wheel 241, and the output shaft of the hub motor 242 is connected to the driving wheel 241; the driving wheels 24 are the front and rear two wheels on the same side of the vehicle body 1, and the wheels on the other side are driven wheels. Thus, both the manufacturing cost is saved and the side shift of the vehicle body 1 can be ensured not to deviate;

[0060] The driving wheel 241 and the vehicle tire are arranged at a 90-degree angle. Relative to the front and rear movement of the vehicle wheels, the landing gear wheels can only move left and right.

[0066] In some embodiments of the present invention, as Figure 8 shown, the control panel 3 includes control buttons 31; the control panel 3 is arranged in the cab at a place convenient for the driver to access and operate, such as the center console, the main driver's door panel, etc.; the control panel 3 is electrically connected to the hub motor 242 and the hydraulic oil pump 41; the control buttons 31 are evenly arranged on the control panel 3, and the control buttons 31 include eight control buttons: "start", "stop", "landing gear retract", "landing gear extend", "vehicle lift", "vehicle lower", "left" and "right";

[0067] The power supply 32 is electrically connected to the control panel 3, the hub motor 24 and the hydraulic oil pump 41. The power supply 32 is used to supply power to the above-mentioned electrical equipment. Specifically, when the vehicle body 1 is a fuel vehicle, the power supply 32 is the starting battery of the vehicle body 1 itself. When in use, the engine of the vehicle body 1 does not turn off and runs at idle speed to supply power to the starting battery. The power supply 32 includes a voltage boosting device, and when in use, the engine of the vehicle body 1 runs to charge the battery of the power supply 32; when the vehicle body 1 is a pure electric vehicle or a plug-in hybrid vehicle, the power supply 32 can directly use the power battery inside the vehicle body 1 and directly supply power to the electrical equipment through the power battery;

[0068] The hydraulic oil station 4 (not shown in the figure) includes a hydraulic oil pump 4 and hydraulic oil pipes 42; the hydraulic oil station 4 is arranged in the engine compartment or the trunk of the vehicle body 1, etc.; the hydraulic oil pump 4 is electrically connected to the control panel 3 and is controlled by the control buttons 31; the hydraulic oil pipes 42 are used to connect the oil inlet and outlet of the hydraulic oil pump 4 and the oil inlet and outlet of the first hydraulic cylinder 22, the second hydraulic cylinder 23 and the third hydraulic cylinder 26. Thus, the hydraulic oil inside the hydraulic oil station 4 enters the first hydraulic cylinder 22, the second hydraulic cylinder 23 and the third hydraulic cylinder 26 through the hydraulic oil pump 41 and the hydraulic oil pipes 42 to control the expansion and contraction of the relevant hydraulic cylinders;

[0069] When a small car landing gear device 100 that can move laterally is in use, first park the vehicle body 1 on a flat surface. If the vehicle body 1 is a fuel vehicle, it idles, pull up the handbrake, and control the small landing gear device 2 through the control button 31 on the control panel 3. When the "start" button is pressed, the electrical equipment of the vehicle rapid lifting and displacement device 100 is connected to the power supply 32 and powered on; when the "stop" button is pressed, the electrical equipment of the vehicle rapid lifting and displacement device 100 is disconnected from the power supply 32; when the "landing gear retract" button is pressed, as Figure 3 and Figure 4 shown, the hydraulic oil pump 41 sends hydraulic oil into the first hydraulic cylinder 22 and the third hydraulic cylinder 26 through the hydraulic oil pipe 42. The first hydraulic cylinder 22 and the third hydraulic cylinder 26 drive the connecting seat 231, the first universal joint 233, the second universal joint 234, the first side support rod 25, the rotating base 251, the second side support rod 27, the connecting bracket 28, the connecting plate 29, the second fixed seat 291, and the rotating connecting rod 292 to rotate through expansion and contraction.

The small landing gear device 2 enters the retracted state. At this time, the distance from the lowest point of the small landing gear device 2 to the ground is greater than 100 mm;

[0071] When the "car lift" button is pressed, the hydraulic oil pump 41 sends hydraulic oil into the second hydraulic cylinder 23 through the hydraulic oil pipe 42. The hydraulic outrigger 24 extends downward, driving the driving wheel 241 to contact the ground downward and supporting the vehicle body 1, so that the wheels of the vehicle body 1 leave the ground;

[0072] When the "car lower" button is pressed, the hydraulic oil in the second hydraulic cylinder 23 flows back to the hydraulic oil station 4 through the hydraulic oil pipe 42. The hydraulic outrigger 24 retracts upward, driving the driving wheel 241 to disengage from the ground upward. The vehicle body 1 descends, and the wheels of the vehicle body 1 contact the ground;

[0073] When the "left" button is pressed, the hub motor 242 rotates. After the speed reduction and torque increase of the transmission seat 243, it drives the driving wheel 241 to move to the left;

[0074] When the "right" button is pressed, the hub motor 242 rotates in the reverse direction. After the speed reduction and torque increase of the transmission seat 243, the driving wheel 241 is driven to move to the right;

[0075] The present invention and its embodiments have been described above. Such description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto.
