[0039] Furthermore, a guide sleeve 209 is fixedly provided on the inner wall of the cylinder 204 , and the push rod 208 slides through the guide sleeve 209 .

[0040] Furthermore, the transmission mechanism 202 is a reduction gearbox, including a box body 2021 and an input gear 2022, an intermediate gear 2023 and an output gear 2024 arranged in the box body 2021 and meshed in sequence. The input gear 2022 is sleeved on the power input shaft and connected to the output end of the second drive mechanism 201 through the power input shaft. The intermediate gear 2023 is sleeved on the intermediate shaft. The output gear 2024 is sleeved on the screw 203 and fixedly connected to the screw 203.

[0041] In the embodiment described in the present invention, it is understood that the first driving mechanism 104 is any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder. Furthermore, the first driving mechanism 104 can also be a motor screw mechanism.

[0042] In the embodiment described in the present invention, it can be understood that the second driving mechanism 201 is a servo motor or a stepper motor, and usually the output end of the motor will be connected to a reducer to form a reduction motor, which is then connected to the transmission mechanism 202 to output corresponding power.

[0043] In the embodiment described in the present invention, the working stages of the leveling device can be divided into three stages: preparation, leveling and retraction.

[0044] Preparation stage: The leveling support mechanism 400 is in the storage state. After receiving the command, the first driving mechanism 104 contracts first, driving the upper arm 101 and the lower arm 103 to rotate around the corresponding pin shaft to a horizontal state; the movement of the upper arm 101 and the lower arm 103 causes the support leg 200 to move to the outside of the vehicle platform 300 and to be located in the working position.

[0045] Leveling stage: Second drive mechanism 201 provides driving torque, reduces the shaft speed via a speed reducer, and transmits the power to transmission mechanism 202. Within housing 2021, power is transmitted from the power input shaft to lead screw 203 via the power input shaft and its connected input gear 2022, the intermediate shaft and its connected intermediate gear 2023, and the lead screw 203 and its connected output gear 2024. Within cylinder 204, as lead screw 203 rotates while maintaining a constant spatial position, it drives its mating nut 207 downward. The movement of nut 207 extends push rod 208, which engages guide sleeve 209, ensuring a stable motion trajectory. The extension of push rod 208 pushes ball head 206 and landing plate 205 downward, ultimately supporting landing plate 205 in contact with the ground. The legs 200 prop up the vehicle, lifting it off the ground. By controlling the rotation amount of the second driving mechanism 201 , the extension amount of the leveling legs 200 can be accurately controlled, thereby achieving leveling of the vehicle-mounted platform 300 .

[0046] Retraction Phase: Due to the significant gravity of the vehicle-mounted platform 300, the ground exerts a vertical upward force on the floor plate 205, which is transmitted to the ball head 206, push rod 208, and nut 207. The second drive mechanism 201 is activated and reversed. The resulting torque, through the reducer and transmission mechanism 202, drives the lead screw 203 in reverse, causing the nut 207 to move upward, thus providing space for the push rod 208 and the floor plate 205 to move upward. Under the reaction force of gravity, the floor plate 205 and push rod 208 move upward synchronously, achieving the retraction of the legs 200. After the legs 200 are fully retracted, the first drive mechanism 104 extends, driving the entire assembly to fold and retract above the vehicle-mounted platform 300.

[0048] This embodiment discloses a foldable storage vehicle-mounted platform leveling device. The difference between this embodiment and Example 2 is that the transmission mechanism 202 includes a first pulley and a second pulley arranged in a box body 2021.

The second pulley is mounted on the screw 203. The first pulley and the second pulley are connected by a belt.

[0053] It can be understood that when the leveling support mechanism 400 is folded and retracted into the storage box 600, the leveling support assembly composed of the leveling support mechanism 400 and the storage box 600 is also located within the area enclosed by the vehicle platform 300, that is, in the horizontal plane, the entire leveling support assembly is located within the rectangular area enclosed by the four sides of the vehicle platform 300.

[0054] Furthermore, a level sensor is installed in the middle of the vehicle frame. This sensor detects the levelness of the vehicle-mounted platform 300 and records its inclination in real time. Based on the feedback, the electronic control system adjusts the extension and retraction of the corresponding legs 200 to ensure that the vehicle-mounted platform 300 is level. Only after leveling is complete can the equipment on the vehicle-mounted platform 300 be operated.

[0055] Furthermore, a cabin 500 is provided on the vehicle-mounted platform 300 , and electrical equipment is provided in the cabin 500 .
