[0005] Furthermore, the bladder is distributed into an upper zone, a middle zone and a lower zone, the upper zone and the lower zone of the bladder have the same diameter, the diameter of the middle zone is larger than the diameters of the upper and lower zones, and the middle diameter of the middle zone is larger than the upper and lower diameters of the middle zone.
[0006] Furthermore, the upper buckling ring is located on the outer wall of the upper area of the bladder, the upper buckling ring and the upper air chamber ring form a sandwich that clamps the upper area of the bladder, the ring mouth is located at the top of the upper area of the bladder, and the clamping groove is formed between the top of the upper buckling ring and the ring mouth.
[0007] Furthermore, the opening of the snap ring groove faces the bladder, and the upper end of the guide cylinder is provided with a ring buckle protruding outward, and the ring buckle is installed corresponding to the snap ring groove.
[0008] Furthermore, the snap ring groove is located below the middle of the middle area of the bladder.
[0009] Furthermore, the protective cover is provided with a plurality of folds, and an annular cavity is formed between the folds and the bladder.
[0010] Furthermore, the protective cover is in an outwardly convex arc shape at a middle area corresponding to the bladder.
[0011] Compared with the prior art, the utility model proposes a new type of hollow spring bladder protective cover adopts the above technical solution and achieves the following technical effects:
[0012] The utility model can provide wrapping protection for the external part of the air suspension bladder of the vehicle to avoid being hit by foreign objects and eroded by liquids; the protective cover has a simple and compact structure; the protective cover structure can be stretched and compressed, can follow the movement of the bladder, and is not easy to fall off; maintenance and replacement are convenient, and quick replacement can be achieved by simply removing the shock absorber; the structure has high versatility and can match front suspension overhead spring designs of different sizes.

[0017] Example
[0018] Please refer to Figure 1The utility model proposes a novel protective cover for an empty spring bladder 4, comprising a bladder 4 and an upper air chamber ring 1. A ring opening 6 larger than the diameter of the bladder 4 is arranged at one end of the bladder 4. An upper buckling ring is installed on the outer wall of the bladder 4 and an annular clamping groove 7 is formed between the ring opening 6. A protective cover is sleeved on the outer side of the bladder 4 and clamped in the clamping groove. A guide cylinder 5 is sleeved on the other end of the bladder 4. A clamping ring groove 8 for clamping the guide cylinder 5 is formed between one end of the protective cover close to the guide cylinder 5 and the bladder 4, and one end of the guide cylinder 5 is meshed with the clamping ring groove 8. In the utility model, the upper end of the bladder 4 is installed with a protective cover by installing an upper pressing ring. The upper pressing ring will not slide downward due to the distribution of the upper area 41 and the lower area 43 of the bladder 4. At the same time, the upper end of the protective cover will be restricted in the clamping groove, and the protective cover is also wrapped in a ring outside the bladder 4, so it will not slide left and right and fall off. The protective cover can wrap the entire bladder 4 inside to prevent it from being hit by external debris. Furthermore, the protective cover is made of metal anti-corrosion material, which is elastic and can deform with the deformation of the bladder 4. It can also provide protection when the bladder 4 is working.
[0019] In a specific embodiment, refer to Figure 1 The skin bag 4 is divided into an upper area 41, a middle area 42 and a lower area 43. The upper area 41 and the lower area 43 of the skin bag 4 have the same diameter, the diameter of the middle area 42 is larger than the diameters of the upper area 41 and the lower area 43, and the middle diameter of the middle area 42 is larger than the upper and lower diameters of the middle area 42. The middle area 42 of the skin bag 4 can be deformed, and its diameter increases and decreases from the upper area 41 to the lower area 43. Only the diameters of the two ends of the middle area 42 are equal to the diameters of the upper area 41 and the lower area 43. Therefore, the upper buckling ring will not fall to the position of the middle area 42 in the upper area 41, and the guide cylinder 5 will not rise to the position of the middle area 42.
[0020] In a specific embodiment, refer to Figure 1 The upper buckling ring is located on the outer wall of the upper area 41 of the bladder 4, and the upper buckling ring and the upper air chamber ring 1 form a sandwich that clamps the upper area 41 of the bladder 4. The ring opening 6 is located at the top of the upper area 41 of the bladder 4, and the clamping groove is formed between the top of the upper buckling ring and the ring opening 6. When the upper end of the protective cover is located in the clamping groove, the upper end of the protective cover will be in a suspended state, but the position can be limited by the clamping groove.
[0021] In a specific embodiment, refer to Figure 1 The opening of the snap ring groove 8 faces the bladder 4, and the upper end of the guide cylinder 5 is provided with a ring buckle 51 protruding outward, and the ring buckle 51 is installed corresponding to the snap ring groove 8. Since the lower end of the protective cover has a certain diameter, the guide cylinder 5 is clamped between the bladder 4 and the protective cover, and the guide cylinder 5 has an external support effect, so the lower end of the protective cover can be limited by the external support.
[0022] In a specific embodiment, refer to Figure 1 The snap ring groove 8 is located below the middle of the middle area 42 of the leather bag 4.
[0023] In a specific embodiment, refer to Figure 1 The protective cover is provided with a plurality of folds, and an annular cavity 31 is formed between the folds and the leather bag 4. The folds on the protective cover can be pulled up, so that the protective cover has a certain deformation effect, and the cavity formed can further reduce the noise.
[0024] In a specific embodiment, refer to Figure 1 The protective cover is in an arc shape convex outward at the middle area 42 of the leather bag 4. The arc shape of the middle area 42 of the protective cover can provide storage space when the leather bag 4 is contracted.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
