[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 1 An improved suspension structure is shown, including a frame 4, which is connected to a vertically movable link frame 3 via a bushing 7 and a first axle 10. The link frame 3 is connected to a vertically movable sway frame 2 via a bearing 8, a bushing 9, and a second axle 12. The sway frame 2 is movably connected to the frame 4 via a shock absorber 5 and is connected to an integrated rear axle 1.

[0027] The shock absorber 5 is movably connected to the swing frame 2 and the frame 4 at both ends via spherical bearings 6 and screws 11, respectively. Since the shock absorber 5 is connected at both ends by spherical bearings 6, when the swing frame 2 swings up, down, left, and right, the spherical bearings 6 can relieve the hard force exerted by the swing frame 2 on the shock absorber 5, and also relieve the hard force exerted by the shock absorber 5 on the frame 4.

[0028] like Figures 1-3 As shown, the connecting frame 3 is U-shaped, including a first horizontal support and two first vertical supports. A first sleeve is installed at one end of the first vertical support. The first sleeve is concentrically arranged with the bushing 7 and the first axle 10, allowing the connecting frame 3 to swing up and down. A second sleeve is provided in the middle of the first horizontal support. The connecting frame 3 is laterally connected to the vehicle frame 4 through the bushing 7 and the first axle 10. The bushings 7 and axles 10 on the left and right sides are ensured to be concentric, allowing the rear of the connecting frame 3 to swing up and down laterally.

[0029] like Figures 4-8 As shown, the swing frame is U-shaped, including a second horizontal support and two second vertical supports. One end of the second vertical support is connected to an integrated rear axle. A middle support is provided in the middle of the second horizontal support. The middle support has a first lug. The first lug is movably connected to the second sleeve through a second shaft, bearing, bushing, and a second sleeve, allowing the swing frame to swing horizontally up and down synchronously with the connecting frame or to swing vertically up and down independently. The swing frame 2 is longitudinally and transversely connected to the connecting frame 3 through a bearing 8, bushing 9, and second shaft 12, allowing the swing frame 2 to swing horizontally up and down together with the connecting frame 3, or to swing vertically up and down independently.

[0030] like Figure 9 As shown, the shock absorber 5 can only contract and cannot extend. When the shock absorber 5 on one side of the swing frame 2 needs to contract, the swing frame 2 will swing upward laterally and upward longitudinally. Therefore, the shock absorber 5 between the frame 4 and the swing frame 2 will have angular changes in both the lateral and longitudinal directions. Taking advantage of the feature that the spherical bearing 6 can change at multiple angles, spherical bearings 6 are installed at both ends of the shock absorber 5 to eliminate the stiff force generated by the angular change when the shock absorber contracts.

[0031] like Figures 10-11 As shown, the integrated rear axle 1 is connected to the swing frame 2. When the single-sided shock absorber 5 on the swing frame 2 retracts and changes position, the integrated rear axle 1 also changes position. When the swing frame 2 remains horizontal, the integrated rear axle also remains horizontal.

[0032] like Figures 4-11As shown, the swing frame 2 is added, so that the integrated rear axle 1 can swing up and down horizontally and vertically, and the joint bearing 2 has multi-angle flexibility, which can unload various swing forces on the shock absorber 5, and the vehicle using the integrated rear axle 1 can retract the shock absorbers 5 on both sides at any time according to the road conditions, so that the vehicle has better stability and better comfort.

[0033] The utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
