For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, an assembled elastic hinge seat includes a top seat 1, an intermediate seat 2, a base 3 and a built-in shock-absorbing component 4; the top seat 1 is fixed to the outer bottom surface of the rear of the cargo box 500; the upper part of the intermediate seat 2 is assembled on the top seat 1; the base 3 is assembled on the lower part of the intermediate seat 2, and a hinge hole for hinged connection with the frame 600 is provided on the base 3; the built-in shock-absorbing component 4 is arranged between the base 3 and the intermediate seat 2, and is used to ensure that the frame 600 and the assembled elastic hinge seat 100 are subjected to uniform force.

[0047] The above-mentioned adjusting components are further described below.

[0048] Continue to refer to Figure 1 , Figure 2 As shown, the assembled elastic hinge seat also includes an adjusting component 5, which is composed of at least one adjusting gasket stacked on top of each other. By increasing or decreasing the number of adjusting gaskets, it is ensured that the compression amount of the built-in shock-absorbing component 4 and the compression amount of the external shock-absorbing component 400 at the bottom of the cargo box 500 are consistent when the cargo box 500 is under load.

[0049] The above base is further described below.

[0050] like Figure 2 , Figure 3 , Figure 4 As shown, the base 3 includes a mounting portion and a hinged portion; the mounting portion has a accommodating cavity with an opening toward the top seat 1, which is used to hold the lower portion of the middle seat 2 and the built-in shock-absorbing component 4; the hinged portion is installed on the outer bottom surface of the mounting portion, and the hinged portion is composed of a pair of vertical plates opposite to each other, and each of the two vertical plates is provided with a coaxially arranged reaming hole.

[0051] Preferred solution: Figure 5 As shown, a reinforcing rib plate is welded between the outer side surface of the vertical plate and the bottom plate of the mounting portion, and a reinforcing rib plate is welded between the two vertical plates; the built-in shock-absorbing component 4 uses built-in shock-absorbing rubber.

[0052] Further solutions: Figure 2 As shown, at least one coaxially arranged through hole is provided on the bottom plate of the mounting portion, the lower portion of the middle seat 2 and the built-in shock absorbing component 4. After the bolt 8 passes through the through holes of the three, the three are fixed together after being tightened by a nut.

[0053] Further solutions: Figure 2 As shown, when the nut is tightened on the bolt 8, a radial through hole is provided on the circumferential surface of the rod portion of the bolt 8 near the nut, and a safety pin 10 is inserted into the radial through hole to prevent the nut from falling off the bolt 8.

[0054] Further solutions: Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the base 3 also includes a limiting component 6, which is fixed on a mounting portion between the two vertical plates and close to the rear end of the vertical plates. The limiting portion 6 includes a U-shaped plate protruding toward the frame. When the cargo box 500 is lifted to a preset angle, the U-shaped plate contacts the frame 600 to limit further lifting of the cargo box 500.

[0055] Preferred solution: Figure 3 As shown, the limiting component 6 also includes a supporting plate, which is welded in the U-shaped plate and is also welded to the bottom plate of the mounting portion.

[0056] Further solutions: Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the base 3 also includes a safety shaft 7, which includes a cylindrical component and a latch; the cylindrical component is installed on the outer plate of one of the vertical plates; the latch is installed in the cylindrical component and can move axially in the cylindrical component. When the cargo box 500 is lifted to a preset angle, the latch can be inserted into the safety sleeve hole 300 on the frame 600.

[0057] Further solutions: Figure 8 As shown, a U-shaped slideway is provided on the circumferential surface of the cylindrical component, and the handle of the latch acts on the slideway. By pushing and pulling the handle, the cylinder of the latch is axially moved in the cylindrical component.

[0058] Preferred solution: a reinforcing rib plate is welded between the cylindrical component and the vertical plate and the bottom plate of the mounting portion.

[0059] A further solution is as follows: the top seat 1 is fixed to the outer bottom surface of the rear part of the cargo box 500 by welding; the upper part of the middle seat 2 is fixed to the top seat 1 by bolts 9.

[0060] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, during implementation, the top seat 1 needs to be welded to the bottom of the cargo box 500 first, and the middle seat 2 is pre-tightened with the top seat 1 through bolts 9, and an adjustment gasket is installed between the middle seat 2 and the top seat 1. The base 3 is hinged with the frame 600 through the shaft 200, and the internal shock-absorbing rubber (internal shock-absorbing component 4) is installed in the base 3. According to the thickness of the external shock-absorbing rubber (external shock-absorbing component 400) installed at the bottom of the cargo box 500, the number of adjustment gaskets between the middle seat 2 and the top seat 1 is adjusted to ensure that the compression amount of the internal shock-absorbing rubber (internal shock-absorbing component 4) is consistent with the compression amount of the external shock-absorbing rubber (external shock-absorbing component 400) at the bottom of the cargo box 500 when subjected to load. The cargo box 500 is connected to the lifting cylinder 700 through a pin shaft, and the position of the cargo box 500 is fine-tuned until the installation requirements of the lifting cylinder 700 are met. Finally, the bolts 8 and 9 are tightened with a fixed torque, and the safety pin 10 is installed (to prevent the nut from falling off after the internal shock-absorbing rubber is compressed). The position where the shaft 7 is installed in the figure is in a non-working state. When the cargo box 500 needs to be lifted during maintenance, it is lifted to 43°. The safety shaft 7 is rotated to the track through the handle and inserted into the safety sleeve hole 300 on the frame 600 to ensure the safety of maintenance. When the maintenance is completed, the safety shaft 7 is pulled back to the original position. When the hydraulic system controlling the lifting cylinder 700 fails and the cargo box 500 is lifted to 50°, the limit component 6 contacts the frame 600 when the cargo box is lifted to 50°, avoiding rollover accidents caused by the continued lifting of the cargo box 500.

[0061] In summary, the assembled structure effectively improves fault tolerance (the assembled articulated seat has movement in all directions, which can avoid the situation where the cargo box cannot be assembled with the frame and cylinder due to manufacturing errors of the frame, cargo box and lifting cylinder to a certain extent). The built-in shock-absorbing rubber design ensures that the frame and articulated seat are evenly stressed and guarantees service life. The in-situ push-pull safety shaft design ensures safe operation, reduces the labor intensity of workers, and avoids the loss of parts.
