The first bracket 5 can accurately position the vehicle chassis 2 on the support pallet 1. By connecting with the vehicle chassis 2, the first bracket 5 helps to maintain the stability of the vehicle chassis 2 and prevent the vehicle chassis 2 from moving or tilting on the support pallet 1. The first limit assembly 6 can ensure that the position of the vehicle chassis 2 on the support pallet 1 is fixed, prevent the vehicle chassis 2 from moving on the support pallet 1, and maintain stability during the transportation of the vehicle chassis 2.

[0057] The sliding bar 4 connected to the supporting rod 3 can provide a smooth and stable supporting surface, and the vehicle chassis 2 can move on the supporting tray 1, and can also be fixed when it needs to be fixed. The connection between the sliding bar 4 and the supporting rod 3 can be a threaded connection, a pin connection and welding. Optionally, in this solution, the sliding bar 4 and the supporting rod 3 are welded.

[0068] In one embodiment, there are multiple supporting rods 3 , and there are two sliding rods 4 . The multiple supporting rods 3 are disposed between the two sliding rods 4 and connect the sliding rods 4 .

[0069] Multiple support rods 3 can evenly distribute the weight of the vehicle chassis 2 to a larger area, reduce the pressure on a single support point, and thus reduce the risk of structural damage due to local overload. Multiple support rods 3 can provide multiple support points, which can improve the stability of the entire structure, reduce shaking or tilting, and improve the safety of the vehicle chassis 2 during transportation. By dispersing the load, each support rod 3 is subjected to less pressure, which can reduce the stress on the support rod 3 and extend its service life. Multiple support rods 3 are arranged between two skid bars 4 and connect the skid bars 4. The connection between the multiple support rods 3 and the skid bars 4 can be bolted, clamped, pinned, and welded. This connection can form a stable structure, prevent the skid bars 4 from moving sideways or rotating during transportation, and improve overall stability. The load can be evenly dispersed, and the load can be evenly distributed on the skid bars 4, reducing the burden of a single skid bar 4, and avoiding overload and potential damage.

[0070] In one implementation, please refer to Fig.12 The two sliding rods 4 are vertically connected to the two supporting rods 3, the two sliding rods 4 are parallel to each other, and the two supporting rods 3 are parallel to each other.

[0071] In one implementation, please refer to Fig.13 The two sliding rods 4 are vertically connected to the three supporting rods 3, the two sliding rods 4 are parallel to each other, and the three supporting rods 3 are parallel to each other.

[0072] In one implementation, please refer to Fig.14 The two sliding rods 4 are vertically connected to the four supporting rods 3, the two sliding rods 4 are parallel to each other, and the four supporting rods 3 are parallel to each other.

[0074] In one implementation, please refer to Fig.16 The two slide rods 4 are vertically connected to the four supporting rods 3. The four supporting rods 3 are parallel to each other, and the two slide rods 4 are parallel to each other. The four supporting rods 3 parallel to the slide rods 4 are respectively connected to the two supporting rods 3 close to the left and the two supporting rods 3 close to the right.

[0075] In one embodiment, the plurality of supporting rods 3 include a transverse supporting rod 31 and a longitudinal supporting rod 32 , the two ends of the transverse supporting rod 31 are respectively connected to two sliding rods 4 , and the two ends of the longitudinal supporting rod 32 are respectively connected to two transverse supporting rods 31 .

[0076] Please refer to Fig.16 The transverse support rod 31 is perpendicular to the two skid rods 4. The transverse support rod 31 perpendicular to the two skid rods 4 can provide better support and stability, help disperse the load, and prevent the structure from deforming or collapsing. The longitudinal support rod 32 is perpendicular to the transverse support rod 31 and parallel to the skid rod 4. The design of the longitudinal support rod 32 being perpendicular to the transverse support rod 31 can provide additional support for the transverse support rod 31, enhance the stability of the entire structure, and disperse and withstand forces from multiple directions.

[0077] The combination of the transverse support rod 31 and the longitudinal support rod 32 provides multi-dimensional support, which can better adapt to loads of different shapes and sizes and ensure the stability of the load during transportation. With the transverse and longitudinal support rods 3, the vehicle chassis 2 can be evenly distributed over the entire support pallet 1, reducing the burden of a single rod and improving the load-bearing capacity of the entire support pallet 1. The longitudinal support rod 32 connects the transverse support rod 31 to form a stable grid structure, which helps prevent the skid bar 4 from lateral movement or rotation during transportation. The connection between the transverse support rod 31 and the skid bar 4 and the longitudinal support rod 32 and the transverse support rod 31 can be welding, bolt connection and pin connection.

[0078] In one embodiment, the first bracket 5 includes a first sub-bracket 51 and a second sub-bracket 52, and the first sub-bracket 51 and the second sub-bracket 52 are respectively connected to two different supporting rods 3; the first sub-bracket 51 is connected to the vehicle chassis 2 by bolts, and the second sub-bracket 52 is connected to the vehicle chassis 2 by a clamp.

[0079] Please refer to Figure 1, the number of supporting rods 3 is 6 (the first rod to the sixth rod), wherein the first rod and the fourth rod are the two outermost rods in the length direction of the sliding rod 4, and the second rod and the third rod are located between the first rod and the fourth rod. Optionally, the first rod is arranged in parallel with the fourth rod. The fifth rod connects the first rod and the second rod, and the sixth rod connects the third rod and the fourth rod. Optionally, the fifth rod and the sixth rod are parallel to the sliding rod. Among them, a plurality of first sub-brackets 51 are respectively located on the first rod, the second rod, the third rod and the fourth rod. A first sub-bracket 51 is respectively arranged on one end of the first rod and the fourth rod in the length direction of the supporting rod 3; a first sub-bracket 51 is respectively arranged on the other end of the second rod and the third rod in the length direction opposite to each other; a second sub-bracket 52 is respectively arranged on the fifth rod and the sixth rod. The first sub-bracket 51 and the second sub-bracket 52 are respectively connected to different supporting rods 3. Connection points that can adapt to different shapes of the vehicle chassis 2: The shapes of the connection points of the vehicle chassis 2 are different, and the sub-brackets connected to two different supporting rods 3 can help better adapt to this unevenness and provide connection. It can also more evenly disperse the load of the vehicle chassis 2, reduce the burden of a single supporting rod 3, and improve the stability and carrying capacity of the entire support tray 1. At the same time, it can reduce the risk of collapse of the entire first bracket 5 due to single point failure. If one of the sub-brackets has a problem, the other sub-bracket can still maintain the stability of part of the structure. The first sub-bracket 51 is bolted to the vehicle chassis 2 to provide higher connection strength and rigidity. If the first sub-bracket 51 needs to bear a larger load and a tighter fixation, a bolt connection is used. The second sub-bracket 52 is connected to the vehicle chassis 2 by a clamp. The load borne by the second sub-bracket 52 is smaller, and faster installation and disassembly are required, so a clamp connection is used.

[0080] In one embodiment, the first limiting assembly 6 includes a limiting hole 61 , a limiting column 62 and a limiting rod 63 ; the limiting hole 61 is formed on the supporting rod 3 , and the limiting column 62 and the limiting rod 63 are both connected to the supporting rod 3 .

[0081] Please refer to Figure 1, the shape of the limiting hole 61 can be circular, square and elliptical. Optionally, the shape of the limiting hole 61 in this solution is circular, and the circular limiting hole 61 can evenly distribute stress, reduce stress concentration, and reduce the risk of breakage or damage of the limiting hole 61. The circular limiting hole 61 is easy to process, which can make the manufacturing process simpler and more efficient, and reduce manufacturing costs. The limiting uniform stress distribution of the circular hole, and the relatively uniform contact area with the shaft or rod can reduce wear and extend the service life. The shape of the limiting column 62 can be cylindrical, conical and rectangular. Optionally, the shape of the limiting column 62 in this solution is rectangular, and the rectangular limiting column 62 can prevent the rotation of the vehicle chassis 2. The side of the rectangular parallelepiped cooperates with the side, which can limit the rotation of the vehicle chassis 2 in the horizontal direction, ensuring the stability of the vehicle chassis 2 during transportation. Each corner of the rectangular parallelepiped can be used as a positioning point, which helps to ensure that the vehicle chassis 2 is properly aligned in multiple directions. The rectangular shape can provide a larger contact area, which can disperse pressure and reduce wear. The cross-sectional shape of the limit rod 63 can be circular, square and L-shaped. Optionally, the cross-sectional shape of the limit rod 63 in this scheme is a square. The square limit rod 63 can prevent the movement of the vehicle chassis 2, limit the rotation of the vehicle chassis 2 in the horizontal direction, and ensure the stability of the vehicle chassis 2 during transportation. The square limit rod 63 can provide a larger contact area, which can disperse pressure and reduce wear. The method of opening the limit hole 61 on the supporting rod 3 can be drilling, milling, laser cutting, stamping and electrospark machining. The connection method between the limit column 62 and the limit rod 63 and the supporting rod 3 can be threaded connection, welding, snap connection and clamping connection.

[0082] In one embodiment, the limiting hole 61 and the limiting column 62 are respectively arranged on at least two different supporting rods 3 , and the limiting rod 63 connects at least two supporting rods 3 .

[0083] Please refer to Figure 1, two limiting holes 61 are respectively provided on the second rod and the third rod, and the limiting holes 61 are provided at one end in the length direction of the two supporting rods 3; a limiting column 62 is respectively provided at one end in the length direction of the first rod and the fourth rod; and a limiting rod 63 is provided at the other end of the supporting rod 3 which is opposite to each other in the length direction, and the limiting rod 63 connects the four supporting rods 3. The limiting holes 61 and the limiting columns 62 are respectively provided on at least two different supporting rods 3, so that the movement of the vehicle chassis 2 can be more comprehensively and accurately controlled, and the stability and durability of the supporting tray 1 can be enhanced. The limiting holes 61 and the limiting columns 62 are provided on different supporting rods 3 to control the position of the vehicle chassis 2 in two or more dimensions. By dispersing the limiting holes 61 and the limiting columns 62 on different supporting rods 3, the stability of the entire supporting tray 1 can be enhanced, the stress concentration on a single supporting rod 3 can be reduced, and deformation or damage caused by excessive force on a single point can be avoided. The limiting holes 61 and limiting columns 62 are arranged on different supporting rods 3 to optimize according to different connection points of the vehicle chassis 2, thereby improving the adaptability and flexibility of the installation of the vehicle chassis 2. The limiting rod 63 connecting at least two supporting rods 3 can improve the stability, accuracy and safety of the supporting tray 1, while providing more flexible motion control. When the vehicle chassis 2 is large or needs to span a certain distance, a single supporting rod 3 cannot provide sufficient support. By connecting at least two supporting rods 3, the limiting rod 63 can provide support between them, increasing the overall stability of the structure. When the force applied to the vehicle chassis 2 during transportation is large, a single supporting rod 3 cannot bear the entire load. By connecting multiple supporting rods 3, the limiting rod 63 can help disperse and bear the load and reduce the stress concentration of a single supporting rod 3. The limiting rod 63 can reduce the vibration and wear generated during transportation, and by connecting multiple supporting rods 3, the limiting rod 63 can provide a smoother transportation.

[0084] In one embodiment, the first limiting assembly 6 includes a limiting arm 7, which is suitable for supporting the vehicle chassis 2. The limiting arm 7 includes a cross beam 71 and multiple columns 72, at least one column 72 is connected to the supporting rod 3, at least another column 72 is connected to the skid rod 4, and the cross beam 71 connects one end of the column 72 away from the supporting rod 3 and the skid rod 4.

[0085] Please refer to Fig.17, a crossbeam 71 is parallel to the supporting rod 3, a column 72 connects a skid bar 4 and the crossbeam 71, and a column 72 connects a supporting rod 3 and the crossbeam 71. The limiting arm 7 is suitable for supporting the vehicle chassis 2, and can improve the vertical support of the vehicle chassis 2 to prevent the vehicle chassis 2 from jumping in the vertical direction during transportation, resulting in damage to the vehicle chassis 2. It can provide good structural strength, stability and flexibility, and can effectively support and limit the vehicle chassis 2. The crossbeam 71 is the main load-bearing part of the limiting arm 7, connecting multiple columns 72 to provide a support frame for the entire limiting arm 7, ensuring that the limiting arm 7 remains upright and stable when supporting the vehicle. The crossbeam 71 connects the columns 72, transfers the weight of the vehicle chassis 2 to the columns 72, and further disperses it to the supporting rod 3 and the skid bar 4 through the columns 72.
