[0026] Below, in conjunction with the accompanying drawings and specific embodiments, the present invention is further described:

[0027] like Figure 1 、 2, 3, 4, 5, and 6 show a support frame of an air suspension assembly of the present invention, which includes a base frame 10, two side frames 20, and two end frames 30, wherein the two side frames 20 are respectively mounted on both sides of the base frame 10, and the two end frames are respectively mounted on both ends of the base frame 10 and can be fixedly matched with the base frame 10; the side frame 20 includes a bottom side beam 22 and a top side beam 21, and a connecting beam 24 extending in the height direction is fixed between the two ends of the bottom side beam 22 and the top side beam 21. The side frame 20 is placed Above the side of the chassis 10, the bottom side beam 22 is fixedly matched with the chassis 10; three clamping assemblies arranged along the length direction of the top side beam 21 are provided on each top side beam 21, and the clamping assemblies on the two top side beams 21 correspond to each other in pairs, that is, three groups of clamping assemblies are provided on the top of the two side frames 20 respectively; the clamping assembly includes a first mounting seat 42, a second mounting seat 43, a clamp 44, a pull rod 45, and a locking member, wherein the first mounting seat 42 and the second mounting seat The first and second mounting seats 42 and 43 are arranged on the top side beam 21, and the first mounting seat 42 and the second mounting seat 43 are arranged along the length direction of the top side beam 21 and are arranged opposite to each other. One end of the clamp 44 is hinged on the first mounting seat 42, and the other end can be placed on the second mounting seat 43 after rotation. One end of the pull rod 45 is hinged on the second mounting seat 43, and the other end can be passed through the groove opened at the other end of the clamp 44. The locking piece is fixed to the other end of the pull rod 45 and pressed on the other end of the clamp 44. The first mounting seat 42, the second mounting seat 43, and the clamp 44 together form a hole for the shaft of the suspension assembly to pass through. That is to say, after the shaft of the suspension assembly is placed between the first mounting seat 42 and the second mounting seat 43, the clamp 44 can be rotated and placed above the shaft of the suspension assembly, and the other end of the clamp 44 is pressed by the locking piece, and then the shaft of the suspension assembly is pressed against the first mounting seat 42 and the second mounting seat 43 by the clamp 44 to fix the shaft of the suspension assembly.

[0028] When storing the air-suspended component, the base frame 10 is supported on the ground, and the two ends of the shaft of the air-suspended component are respectively placed on the two corresponding clamping components on the two top side beams 21, and the shaft is pressed and fixed on the first mounting seat 42 and the second mounting seat 43 using the clamps 44 on the two clamping components. Compared with the prior art, the present invention directly places the shaft of the air-suspended component on the two side frames 20, and uses the clamping components to clamp and fix the two ends of the shaft of the air-suspended component, so that the air-suspended component can be firmly fixed on the support frame. It is only necessary to tighten the locking piece and the pull rod to clamp the shaft of the air-suspended component. There is no need for bundling operation, which simplifies the operation steps. When disassembling the air-suspended component, loosen the locking piece and pull the clamp open so that the support frame can be reused.

[0029] It should be noted that the number of clamping assemblies provided on the top side beam 21 is optional. It may be provided with only one or two, or more than three clamping assemblies may be provided as needed.

[0030] In the present invention, a first pad 421 is arranged on the first mounting seat 42, and a second pad 431 is arranged on the second mounting seat 43. The first pad 421 and the second pad 431 are both arranged at an angle, and the two pads together form a V-shaped groove. When the shaft of the air-suspended component is placed between the first pad 421 and the second pad 431, it can be prevented from shaking along the length direction of the base frame 10. Then, the shaft of the air-suspended component is tightened by the clamp 44. The clamp 44 is set to an arc with an upward protrusion in the middle to adapt to the external shape of the shaft, thereby increasing the contact area between the clamp 44 and the surface of the shaft when the shaft is tightened.

[0031] The above-mentioned locking member is a locking nut (not shown in the figure), which is screwed on the other end of the pull rod 45. When fixing the air suspension component, the other end of the clamp 44 is placed on the second mounting seat 43, and the pull rod 45 is inserted into the groove on the clamp 44, so that the other end of the clamp 44 is placed under the locking nut, and the locking nut is tightened so that the locking nut fully presses the other end of the clamp 44, and finally the clamp 44 presses the surface of the shaft. The locking nut can be tightened by an electric tool to further improve efficiency.

[0032] The support frame of the present invention can also be folded to reduce the occupied space when not in use, and multiple support frames can be stacked; wherein, the clamping assembly can be folded toward one side of the side frame 20, that is, when the air-suspended assembly is fixed, the support assembly is placed above the above-mentioned top side beam 21, and when not in use, the support assembly is folded to one side of the top side beam 21. Specifically, the support assembly also includes a mounting plate 41, and the first mounting seat 42 and the second mounting seat 43 are both fixed on the mounting plate 41. One side of the mounting plate 41 is hinged to the top of one side of the top side beam 21 through a hinge 211. The rotation axis of the hinge 211 is consistent with the length direction of the top side beam 21. When not in use, the mounting plate 41 is flipped downward 180 degrees to make the entire clamping assembly be located on one side of the top side beam 21.

[0033] Furthermore, two longitudinal beams 12 are provided on the chassis 10, which are respectively located below the two bottom side beams 22. The bottom side beams 22 of the two side frames 20 are respectively supported above the two longitudinal beams 12. A baffle 23 is fixed on both sides of the two ends of the bottom side beam 22. The baffle 23 extends downward from the side of the bottom side beam 22 and protrudes from the lower surface of the bottom side beam 22. The two baffles 23 are respectively clamped on both sides of the longitudinal beam 12 below the bottom side beam 22, which is equivalent to forming a groove by the two baffles 23. The longitudinal beam 12 is placed in the groove, so that the side frame 20 and the chassis 10 are fixed in a detachable manner; at the same time, the side frame 20 of the present invention can be folded inward to fold. Placed on the base frame 10, specifically, a vertical beam 11 extending upward is respectively provided at the four end corners of the base frame 10, and the two side frames 20 are respectively installed between the two vertical beams 11 on both sides of the base frame 10, that is, the side frame 20 is aligned with the position between the two vertical beams 11 and assembled with the base frame 10, so that the connecting beams 24 at both ends of the side frame 20 are respectively placed on the inner sides of the two vertical beams 11, and a slide groove 113 extending in the height direction is provided on the vertical beam 11, and a pin 241 is fixed on the connecting beam 24, which is slidably embedded in the slide groove 113, and the pin 241 can rotate relative to the vertical beam 11 when it slides to any position of the slide groove 113, see Figure 6As shown, the side frame 20 can be lifted upward to separate the baffle 23 on the bottom side beam 22 from the longitudinal beam 12, and the side frame 20 on one side can be folded inward 90 degrees so that it can be placed horizontally on the bottom frame 10. After the side frame 20 on the other side is lifted upward to a slightly higher height, it can be folded inward 90 degrees and then placed horizontally on the side frame 20 that was folded first. In this way, the two side frames 20 are stacked on the bottom frame 10. The end frame 30 of the present invention can be folded inward and stacked on the side frame 20 of the upper layer. Specifically, the two end frames 30 are rotatably connected to the two ends of the bottom frame 10, and a fixing component is provided between the end frame 30 and the bottom frame 10. The fixing component is fixed when the end frame 30 is rotated to the same position as the bottom frame 10. When the base frame 10 is in a vertical state, the end frame 30 is fixed to the base frame 10. A column 31 extending in the height direction is respectively provided on both sides of the end frame 30. A cross beam 32 is fixed between the two columns 31. The bottoms of the two columns 31 on the end frame 30 are respectively sleeved on the two vertical beams 11 in the width direction of the base frame 10, so that the end frame 30 can slide relative to the base frame 10 in the height direction. A fixed shaft 111 is provided on the vertical beam 11. The fixed shaft 111 extends in the width direction of the base frame 10. A guide groove 311 extending in the height direction is provided on the column 31. The fixed shaft 111 is connected to the guide groove 311 and can slide in the extension direction of the guide groove 311. The fixing component includes a fixed shaft 111 provided on the vertical beam When the bracket 31 is in the upright position, the bracket 31 is in the upright position, and the bracket 31 is in the upright position, so that the bracket 31 is in the upright position. When the bracket 31 is in the upright position, the bracket 31 is in the upright position, so that the bracket 31 is in the upright position, and the bracket 31 is in the upright position, the bracket 31 is in the upright position, so that the bracket 31 is in the upright position, and the bracket 31 is in the upright position. Finally, it is stacked on the side frame 20 located above, and the support frame is finally folded, thereby reducing the space occupied by the support frame, and multiple folded support frames can be stacked; when the support frame needs to be used, the two end frames 30 are first lifted up to a certain height, and then the end frames 30 are turned outward 90°, and the end frames 30 are moved downward along the height direction so that the clamping plates 312 are snapped into the clamping slots, and then the side frames 20 located above are first lifted a short distance and then turned outward 90°, and then dropped, and the baffles 23 at the bottom of the side frames 20 are clamped on both sides of the longitudinal beams, and the other side frame 20 is matched with the base frame 10 in the same way, and finally, the support assembly is flipped over to the top of the top side beam 21.

[0034] In order to increase stability, the side frame 20 and the end frame 30 are further fixed together by a latch 33. Before folding, the latch 33 can be pulled out.

[0035] In addition, a fixing rod 25 extending in the height direction is fixed to the bottom side beam 22 and the top side beam 21. A support member 26 is installed on the fixing rod 25 to support the suspension assembly on the outside. Specifically, the support member 26 includes a sleeve 261 rotatably sleeved on the outside of the fixing rod 25 and a supporting cross bar 262 fixed on the sleeve 261. The bottom of the sleeve 261 is evenly distributed with a plurality of limit slots 263 with openings facing downwards. There are multiple outwardly protruding limit blocks 251, and the multiple limit blocks 251 are embedded in the multiple limit grooves 263 in a one-to-one manner. When the suspension assembly needs to be supported, the sleeve 261 is lifted upward, and then the support cross bar 262 is rotated outward at a certain angle, and then the sleeve 261 is moved downward so that the limit blocks 251 are embedded in the limit grooves 263 in a one-to-one manner. When it needs to be folded, the sleeve 261 is lifted upward, the support cross bar 262 is rotated outward, and then the sleeve 261 is moved downward.
