[0082] It can be understood that the aforementioned first reducer 240 can be but is not limited to a gear reducer.

[0083] It is understandable that the structure of the first drive assembly 200 and the structure of the second drive assembly 300 can be substantially the same, thereby enabling modular design and assembly of the vehicle-mounted leveling system, which is conducive to improving the installation convenience of the vehicle-mounted leveling system.

[0084] like Figures 1 to 4 As shown, in some examples, the first drive assembly 200 also includes a first hinge support 250, which is connected between the first connection side 230a and the mounting platform 100, and the first hinge support 250 is spaced apart from the first screw transmission part 220; and / or the second drive assembly 300 also includes a second hinge support 350, which is connected between the second connection side 230b and the third connection side 330a, and the second hinge support 350 is spaced apart from the second screw transmission part 320.

[0085] In this technical solution, the first drive assembly 200 may further include the aforementioned first hinge support 250. Based on the aforementioned arrangement, multiple hinge positions may be formed between the mounting platform 100 and the first drive assembly 200, thereby improving the stability and reliability of the mounting platform 100 when rotating about the first direction, and further enhancing the adaptability of the vehicle-mounted leveling system to large-scale operating equipment.

[0086] In this technical solution, the second drive assembly 300 may further include the aforementioned second hinge support 350. Based on the aforementioned arrangement, multiple hinge positions can be formed between the first support plate 230 and the second drive assembly 300, thereby improving the stability and reliability of the mounting platform 100 when rotating about the second direction, and further enhancing the adaptability of the vehicle-mounted leveling system to large-scale operating equipment.

[0087] It is understandable that the vehicle-mounted leveling system can include the aforementioned first hinge support 250 and second hinge support 350 at the same time, which is conducive to improving the overall structural reliability and stability of the vehicle-mounted leveling system and can further improve the adaptability of the vehicle-mounted leveling system to large-scale operating equipment.

[0088] It can be understood that the rotation axis of the first hinge support 250 is axially parallel to the first direction; the rotation axis of the second hinge support 350 is axially parallel to the second direction.

[0089] It can be understood that the number of the aforementioned first hinge supports 250 can be multiple; the number of the aforementioned second hinge supports 350 can be multiple.

[0090] Exemplarily, the first hinged support 250 may include a first pad, a first double-ear support and a first single-ear support, the first single-ear support is hinged to the first double-ear support, the first pad is arranged between the first double-ear support and the first support plate 230, and the first single-ear support is arranged on the mounting platform 100.

[0091] Exemplarily, the second hinged support 350 may include a second pad, a second double-ear support and a second single-ear support, the second single-ear support is hinged to the second double-ear support, the second pad is arranged between the second double-ear support and the second support plate 330, and the second single-ear support is arranged on the first support plate 230.

[0092] In some feasible examples, the maximum load capacity of the mounting platform 100 is greater than or equal to 4 tons; the mounting platform 100, the first support plate 230, and the second support plate 330 all have a roughly square plate-like structure, and the mounting platform 100, the first support plate 230, and the second support plate 330 are each approximately 1.3 meters long and 1.3 meters wide; when the mounting platform 100, the first support plate 230, and the second support plate 330 are parallel to each other, the height of the vehicle-mounted mounting platform 100 is approximately 0.35 meters. Based on this, the vehicle-mounted leveling system can achieve excellent structural compactness and miniaturization, while also having good load-bearing performance, which helps reduce the space requirements of the vehicle-mounted work platform in the working environment.

[0093] In some feasible examples, the vehicle-mounted leveling system may further include an acquisition component and a control component, wherein the acquisition component is used to obtain angle information between the mounting platform 100 and a reference plane, the aforementioned reference plane being perpendicular to the height direction of the vehicle body; the acquisition component, the first drive unit 210 and the second drive unit 310 are all signal-connected to the control component, and the control component is used to control the first output speed of the first drive unit 210 and the second output speed of the second drive unit 310 according to the aforementioned angle information, and the aforementioned first output speed and the aforementioned second output speed both decrease as the aforementioned angle information increases.

[0094] In this technical solution, the vehicle-mounted leveling system may further include the aforementioned acquisition component and the aforementioned control component. Based on the aforementioned configuration, the vehicle-mounted leveling system can utilize the aforementioned control component to control the output rotational speeds of the first drive component 200 and the second drive component 300 to decrease as the inclination angle of the mounting platform 100 relative to the vehicle body increases. This can reduce the rotational speed of the mounting platform 100 during the leveling process when the mounting platform 100 is tilted significantly relative to the vehicle body, facilitating stable horizontal adjustment of the mounting platform 100 and the operating equipment thereon, improving the stability of the vehicle's center of gravity, reducing the risk of the vehicle tipping over, and thereby improving the safety of the vehicle-mounted leveling system and the vehicle.

[0095] It is understandable that the aforementioned acquisition component may be, but is not limited to, an inclination sensor or a visual angle measurement device; and the aforementioned control component may be, but is not limited to, a PLC (Programmable Logic Controller).
