The platform system includes multiple platform units arranged side by side. Each platform unit includes an interconnected tractor unit and a vehicle chassis. A platform is fixed to the upper side of the vehicle chassis, and four support components are centrally symmetrically distributed on the lower side of the vehicle chassis. Each support component includes a first hydraulic cylinder arranged laterally and a second hydraulic cylinder arranged vertically. The cylinder barrel of the first hydraulic cylinder is hinged to the vehicle chassis via a first vertical pivot, and the cylinder barrel of the second hydraulic cylinder is hinged to the piston rod of the first hydraulic cylinder via a second vertical pivot. The piston rod of the second hydraulic cylinder is supported on the ground. An angle is formed between the axis of the first hydraulic cylinder and the central axis of the vehicle chassis, and the axis of the first hydraulic cylinder is offset from the center of the four support components. The assembly method includes the following steps: S1. Move multiple platform units to preset positions in sequence; S2. After each platform unit moves to the preset position, the vehicle chassis is leveled by controlling the extension and retraction of the second cylinder in the four support components, and the vehicle chassis of the platform unit is made to be at the same height as the vehicle chassis of the platform unit in front of it; the vehicle chassis is rotated and translated by controlling the extension and retraction of the first cylinder in the four support components, and the vehicle chassis of the platform unit is aligned with the vehicle chassis of the platform unit in front of it. In step S2, the rotation and translation of the vehicle chassis by controlling the extension and retraction of the first cylinder in the four support components includes the following steps: S2-1. By simultaneously extending the first cylinders in the left front and right rear support assemblies and simultaneously retracting the first cylinders in the right front and left rear support assemblies, the vehicle chassis rotates clockwise. S2-2. By simultaneously retracting the first cylinders in the left front and right rear support assemblies and simultaneously extending the first cylinders in the right front and left rear support assemblies, the vehicle chassis rotates counterclockwise. S2-3. By simultaneously retracting the first cylinders in the left front and right front support assemblies and simultaneously extending the first cylinders in the left rear and right rear support assemblies, the vehicle chassis moves forward. S2-4. By simultaneously extending the first cylinders in the left front and right front support assemblies and simultaneously retracting the first cylinders in the left rear and right rear support assemblies, the vehicle chassis moves backward. S2-5. By simultaneously retracting the first cylinders in the left front and left rear support assemblies and simultaneously extending the first cylinders in the right front and right rear support assemblies, the vehicle chassis moves to the left. S2-6. By simultaneously extending the first cylinders in the left front and left rear support assemblies and simultaneously retracting the first cylinders in the right front and right rear support assemblies, the vehicle chassis moves to the right.

[0005] Furthermore, in the mobile platform system splicing method of the present invention, in step S2, the alignment of the vehicle chassis of the platform unit with the vehicle chassis of the front platform unit means that the front side of the vehicle chassis of the platform unit is flush with the front side of the vehicle chassis of the front platform unit, and the left or right side of the vehicle chassis of the platform unit is parallel to the right or left side of the vehicle chassis of the front platform unit.

[0006] Furthermore, in a mobile platform system splicing method of the present invention, the supporting component further includes a third hydraulic cylinder in a horizontal direction, the cylinder barrel of the third hydraulic cylinder being hinged to the vehicle chassis via a third vertical rotating shaft, and the piston rod of the third hydraulic cylinder being hinged to the cylinder barrel of the first hydraulic cylinder via a fourth vertical rotating shaft.

[0007] Furthermore, in a mobile platform system splicing method of the present invention, the included angle between the axis of the first hydraulic cylinder and the central axis of the vehicle chassis is set as β, where β = 15° to 75°.

[0008] Furthermore, the present invention provides a method for splicing a mobile platform system, wherein β = 45°.

[0009] Furthermore, in a mobile platform system splicing method of the present invention, a support plate is installed at the end of the piston rod of the second hydraulic cylinder via a ball joint; Furthermore, the present invention provides a method for assembling a mobile platform system, wherein the vehicle chassis is provided with multiple wheel sets.

[0010] Furthermore, in a mobile platform system splicing method of the present invention, the first hydraulic cylinders of adjacent support components among the four support components form an outward V-shape or an inward V-shape.

[0011] Compared with existing technologies, the mobile platform system splicing method of this invention has the following advantages: This invention sets up multiple platform units side-by-side, each platform unit including an interconnected tractor unit and a vehicle chassis. A platform is fixed to the upper side of the vehicle chassis, and four support components are arranged symmetrically on the lower side of the vehicle chassis. Each support component has a first hydraulic cylinder arranged laterally and a second hydraulic cylinder arranged vertically. The cylinder barrel of the first hydraulic cylinder is hinged to the vehicle chassis via a first vertical pivot, and the cylinder barrel of the second hydraulic cylinder is hinged to the piston rod of the first hydraulic cylinder via a second vertical pivot, allowing the piston rod of the second hydraulic cylinder to be supported on the ground. The first hydraulic cylinder... An angle is formed between the cylinder's axis and the vehicle chassis's central axis, and the axis of the first cylinder is offset from the center of the four support components. This creates a simple, easy-to-assemble, highly adaptable, and expandable mobile platform system. During assembly, multiple platform units are moved sequentially to preset positions. After each platform unit is moved to its preset position, the vehicle chassis is leveled, rotated, and translated by controlling the extension and retraction of the second and first cylinders in its four support components. This brings the vehicle chassis of each platform unit closer together and aligned. A larger platform is formed by combining the platforms on the vehicle chassis of each platform unit. Compared with existing technologies, this not only reduces the difficulty of assembly operations and improves work efficiency, but also allows for platform expansion by adding more platform units, thus enhancing adaptability and expandability. This invention improves the convenience and flexibility of movement by setting up an interconnected tractor unit and vehicle chassis. By setting four support components symmetrically distributed on the underside of the vehicle chassis, the vehicle chassis can be leveled by extending and retracting the second cylinder in the four support components. By setting an angle between the axis of the first cylinder and the central axis of the vehicle chassis, and by offsetting the axis of the first cylinder from the center of the four support components, the vehicle chassis can be rotated and translated by extending and retracting the first cylinder in the four support components.The specific process of rotating and translating the vehicle chassis is as follows: By simultaneously extending the first cylinders in the left front and right rear support assemblies and simultaneously retracting the first cylinders in the right front and left rear support assemblies, the vehicle chassis can rotate clockwise; by simultaneously retracting the first cylinders in the left front and right rear support assemblies and simultaneously extending the first cylinders in the right front and left rear support assemblies, the vehicle chassis can rotate counterclockwise; by simultaneously retracting the first cylinders in the left front and right front support assemblies and simultaneously extending the first cylinders in the left rear and right rear support assemblies, the vehicle chassis can rotate counterclockwise. The vehicle chassis can be moved forward; it can be moved backward by simultaneously extending the first cylinders in the left front and right front support assemblies and simultaneously retracting the first cylinders in the left rear and right rear support assemblies; it can be moved to the left by simultaneously retracting the first cylinders in the left front and left rear support assemblies and simultaneously extending the first cylinders in the right front and right rear support assemblies; and it can be moved to the right by simultaneously extending the first cylinders in the left front and left rear support assemblies and simultaneously retracting the first cylinders in the right front and right rear support assemblies. This invention provides a mobile platform system splicing method with the advantages of convenient operation and high work efficiency.

[0012] The following detailed description of a mobile platform system splicing method according to the present invention, with reference to the accompanying drawings, illustrates the specific embodiments. Attached Figure Description

[0013] Figure 1 This is a top view of the mobile platform system in this invention. Figure 2 This is a schematic diagram of the first top view of the platform unit in this invention; Figure 3 This is a schematic diagram of the second top view structure of the platform unit in this invention. Detailed Implementation

[0014] First, it should be noted that the directional terms such as up, down, left, right, front, and back used in this invention are merely descriptions based on the accompanying drawings for ease of understanding, and are not intended to limit the technical solution or the scope of protection claimed in this invention.

[0015] like Figures 1 to 3The illustrated embodiment of a mobile platform system of the present invention includes multiple platform units arranged side by side. Each platform unit includes a tractor unit 1 and a vehicle chassis 2 connected to each other. A platform plate is fixed on the upper side of the vehicle chassis 2, and four support components are arranged in a centrally symmetrical distribution on the lower side of the vehicle chassis 2. The support components are equipped with a first hydraulic cylinder 3 arranged laterally and a second hydraulic cylinder 4 arranged vertically. The cylinder of the first hydraulic cylinder 3 is hinged to the vehicle chassis 2 via a first vertical pivot 31, and the cylinder of the second hydraulic cylinder 4 is hinged to the piston rod of the first hydraulic cylinder 3 via a second vertical pivot 41, with the piston rod of the second hydraulic cylinder 4 supported on the ground. An angle is formed between the axis of the first hydraulic cylinder 3 and the central axis of the vehicle chassis 2, and the axis of the first hydraulic cylinder 3 is offset from the center C of the four support components.

[0016] The above structural configuration constitutes a simple, easy-to-assemble, highly adaptable, and expandable mobile platform system. In practical applications, multiple platform units are moved sequentially to preset positions. After each platform unit is moved to its preset position, the vehicle chassis 2 is leveled, rotated, and translated by controlling the extension and retraction of the second hydraulic cylinder 4 and the first hydraulic cylinder 3 in its four support components. This allows the vehicle chassis 2 of each platform unit to move closer together and align. By combining the platform plates on the vehicle chassis 2 of each platform unit, a larger platform can be formed to meet the stage needs of outdoor activities. Compared with existing technologies, this not only reduces the difficulty of assembly operations and improves work efficiency, but also allows for the expansion of the platform by adding platform units, thus improving adaptability and expandability. This invention improves the convenience and flexibility of movement by setting up an interconnected tractor head 1 and vehicle chassis 2. By setting four support components symmetrically distributed on the lower side of the vehicle chassis 2, the vehicle chassis 2 can be leveled by extending and retracting the second cylinder 4 in the four support components. By setting an angle between the axis of the first cylinder 3 and the central axis of the vehicle chassis 2, and making the axis of the first cylinder 3 deviate from the center of the four support components, the vehicle chassis 2 can be rotated and translated by extending and retracting the first cylinder 3 in the four support components. The specific process of rotating and translating the vehicle chassis 2 is as follows: By simultaneously extending the first cylinders 3 in the left front and right rear support assemblies and simultaneously retracting the first cylinders 3 in the right front and left rear support assemblies, the vehicle chassis 2 can rotate clockwise; by simultaneously retracting the first cylinders 3 in the left front and right rear support assemblies and simultaneously extending the first cylinders 3 in the right front and left rear support assemblies, the vehicle chassis 2 can rotate counterclockwise; by simultaneously retracting the first cylinders 3 in the left front and right front support assemblies and simultaneously extending the first cylinders 3 in the left rear and right rear support assemblies, the vehicle chassis 2 can rotate counterclockwise. The vehicle chassis 2 can be moved forward; by simultaneously extending the first cylinders 3 in the left front and right front support assemblies and simultaneously retracting the first cylinders 3 in the left rear and right rear support assemblies, the vehicle chassis 2 can be moved backward; by simultaneously retracting the first cylinders 3 in the left front and left rear support assemblies and simultaneously extending the first cylinders 3 in the right front and right rear support assemblies, the vehicle chassis 2 can be moved to the left; by simultaneously extending the first cylinders 3 in the left front and left rear support assemblies and simultaneously retracting the first cylinders 3 in the right front and right rear support assemblies, the vehicle chassis 2 can be moved to the right.It should be noted that the deviation of the axis of the first hydraulic cylinder 3 from the center of the four support components means that the center of the four support components is not on the axis of the first hydraulic cylinder 3. For those skilled in the art, "leveling the vehicle chassis 2 by extending and retracting the second hydraulic cylinder 4 in the four support components" is known technology, such as the patent with publication number CN102937813A, "A platform center four-point leveling method and leveling system". In practical applications, if the angle between the axis of the first hydraulic cylinder 3 and the central axis of the vehicle chassis 2 is represented by β, setting β to 15° to 75° can achieve the technical purpose of this invention. This invention preferably sets β to 45° to balance the control efficiency of forward and backward movement and left and right movement. The vehicle chassis 2 is provided with multiple wheel sets 21. During leveling, the wheel sets 21 should be in a suspended state. If the tractor 1 affects the stability of the vehicle chassis 2, the connection between the vehicle chassis 2 and the tractor 1 should be disconnected. It should also be noted that this invention is not limited to use as a temporary stage for outdoor activities, but can also be used in other occasions that require a platform.

[0017] In a specific embodiment, the present invention provides a horizontally mounted third hydraulic cylinder 5 in the support assembly. The cylinder barrel of the third hydraulic cylinder 5 is hinged to the vehicle chassis 2 via a vertical third rotating shaft 51, and the piston rod of the third hydraulic cylinder 5 is hinged to the cylinder barrel of the first hydraulic cylinder 3 via a vertical fourth rotating shaft 52. In the moving or non-attached state, the first hydraulic cylinder 3 and the second hydraulic cylinder 4 can be moved to the underside of the vehicle chassis 2 using the third hydraulic cylinder 5, effectively reducing the space occupied. The specific process is as follows: First, the second hydraulic cylinder 4 retracts, allowing the vehicle chassis 2 to be supported by the wheel assembly 21. Then, the first hydraulic cylinder 3 retracts, followed by the retraction of the third hydraulic cylinder 5, thus rotating the first hydraulic cylinder 3 and the second hydraulic cylinder 4 around the first rotating shaft 31 to the underside of the vehicle chassis 2. The process of moving the first hydraulic cylinder 3 and the second hydraulic cylinder 4 to the leveling state is the reverse of the above process and will not be described further here. It should be noted that during the rotation and translation of the vehicle chassis 2, the third hydraulic cylinder 5 should be in a free state, that is, both the forward and reverse hydraulic passages of the third hydraulic cylinder 5 should be in a free-flowing state, so as not to affect the extension and retraction of the first hydraulic cylinder 3. Alternatively, the above technical objective can be achieved by disconnecting the third hydraulic cylinder 5 from the first hydraulic cylinder 3. As a specific embodiment, to improve the stability of the support and its adaptability to the ground, the present invention also installs a support plate 42 at the piston rod end of the second hydraulic cylinder 4 via a ball joint. In practical applications, such as... Figure 2 and Figure 3As shown, the present invention can, as needed, form either an outward V-shape or an inward V-shape for the first cylinders 3 of adjacent support components among the four support components, both achieving the technical objective of the present invention. The terms "outward V-shape" and "inward V-shape" refer to the space enclosed by the four support components. An outward V-shape means that the first cylinders 3 of adjacent support components form an outwardly expanding outward V-shape, while an inward V-shape means that the first cylinders 3 of adjacent support components form an inwardly expanding inward V-shape.

[0018] Based on the same concept, the present invention also provides a method for splicing the above-mentioned mobile platform system, comprising the following steps: S1. Move multiple platform units to the preset positions in sequence.

[0019] S2. After each platform unit moves to the preset position, the vehicle chassis 2 is leveled by controlling the extension and retraction of the second cylinder 4 in the four support components, and the vehicle chassis 2 of the platform unit is made to be at the same height as the vehicle chassis 2 of the platform unit in front of it; the vehicle chassis 2 is rotated and translated by controlling the extension and retraction of the first cylinder 3 in the four support components, and the vehicle chassis 2 of the platform unit is aligned with the vehicle chassis 2 of the platform unit in front of it.

[0020] In step S2, the rotation and translation of the vehicle chassis 2 by controlling the extension and retraction of the first hydraulic cylinder 3 in the four support components includes the following steps: S2-1. By simultaneously extending the first cylinder 3 in the left front and right rear support assemblies and simultaneously retracting the first cylinder 3 in the right front and left rear support assemblies, the vehicle chassis 2 rotates clockwise.

[0021] S2-2. By simultaneously retracting the first cylinder 3 in the left front and right rear support assemblies and simultaneously extending the first cylinder 3 in the right front and left rear support assemblies, the vehicle chassis 2 rotates counterclockwise.

[0022] S2-3. By simultaneously retracting the first cylinders 3 in the left front and right front support assemblies and simultaneously extending the first cylinders 3 in the left rear and right rear support assemblies, the vehicle chassis 2 moves forward.

[0023] S2-4. By simultaneously extending the first cylinder 3 in the left front and right front support assemblies and simultaneously retracting the first cylinder 3 in the left rear and right rear support assemblies, the vehicle chassis 2 moves backward.

[0024] S2-5. By simultaneously retracting the first cylinder 3 in the left front and left rear support assemblies and simultaneously extending the first cylinder 3 in the right front and right rear support assemblies, the vehicle chassis 2 is moved to the left.

[0025] S2-6. By simultaneously extending the first cylinder 3 in the left front and left rear support assemblies and simultaneously retracting the first cylinder 3 in the right front and right rear support assemblies, the vehicle chassis 2 is moved to the right.

[0026] It should be noted that in step S2, aligning the vehicle chassis 2 of the platform unit with the vehicle chassis 2 of the platform unit means that the front edge of the vehicle chassis 2 of the platform unit is flush with the front edge of the vehicle chassis 2 of the platform unit. If the platform units are arranged from left to right, the left edge of the vehicle chassis 2 of the platform unit should be parallel to the right edge of the vehicle chassis 2 of the platform unit. If the platform units are arranged from right to left, the right edge of the vehicle chassis 2 of the platform unit should be parallel to the left edge of the vehicle chassis 2 of the platform unit, to avoid gaps between adjacent platform units. The front platform unit refers to the platform unit that has been leveled, rotated, and translated before the platform unit.

[0027] The splicing method of the mobile platform system provided by the present invention has the advantages of simple operation and high work efficiency.

[0028] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications made by those skilled in the art based on the technical solutions of the present invention without departing from the design concept of the present invention should fall within the scope of protection defined by the claims of the present invention.
