[0002] The shock absorber of a new energy vehicle is a device used to absorb road impact and reduce vehicle vibration. Its basic function is the same as that of the shock absorber of a traditional fuel vehicle.

[0003] Chinese patent publication number CN212643392U, publication time 20201302, discloses a shock absorber for new energy vehicles, whose structure includes a buffer rod body, a connecting valve block, a baffle, an external spring, a connecting rod, a rotating connecting block, and a spring limiting plate. The bottom end of the buffer rod body and the top end of the connecting valve block are an integrated structure. The baffle is arranged on the buffer rod body, and the top end of the connecting rod and the rotating connecting block are an integrated structure. The bottom end of the spring limiting plate is movably in contact with the top end of the external spring. The buffer rod body includes an air push ring, a sealing ring, a sliding rod, a pushing block, a slide groove, a spring rod, a sliding connecting plate, an inner groove, and an outer shell. The bottom end of the air push ring is movably in contact with the top end of the pushing block, and the sealing ring is installed around the sliding rod.

[0004] For example, the existing new energy vehicle shock absorber structure mentioned above adds a sealing ring between the sliding rod and the outer shell to ensure the protection of the connection between the outer tube and the sliding rod to avoid the intrusion of external impurities. In the specific implementation process, as the car runs, the relative movement between the sliding rod and the sealing ring is relatively frequent, and the sealing ring wears and consumes quickly. Therefore, it is urgent to propose a corresponding improved new energy vehicle shock absorber structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to propose an improved shock absorber structure for new energy vehicles in order to solve the above problems.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An improved new energy vehicle shock absorber structure includes a shock absorber body, which includes a sleeve, a valve stem and a spring. The valve stem and the outer wall of the sleeve are respectively fixedly connected with a sliding sleeve and a fixed sleeve. The outer wall of the sliding sleeve is slidably connected to the inner wall of the fixed sleeve. A corrugated sleeve is fixedly connected between the outer walls of the sliding sleeve and the fixed sleeve.

[0008] Preferably, the sleeve and the outer wall of the valve stem are fixedly connected with a barrel ring and an outer ring respectively, the opposite surfaces of the sliding sleeve and the fixed sleeve are fixedly connected with a mounting ring 2, and the two groups of mounting rings 2 are fixedly connected to the barrel ring and the outer wall of the outer ring respectively through two groups of fastening rods.

[0009] Preferably, both sides of the vertical end of the corrugated sleeve are fixedly connected with mounting rings 1, and the two groups of mounting rings 1 are fixedly connected to the sliding sleeve and the fixed sleeve respectively through two groups of locking rods.

[0010] Preferably, the inner surface wall of the sliding sleeve is spaced apart from the spring.

[0012] Preferably, a limiting ring is integrally formed on the outer wall of the arc-shaped end of the outer ring, and the bottom of the limiting ring abuts against the top of the sliding sleeve.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In the present application, as the new energy vehicle is running, the valve stem and the sleeve slide together, and the spring is compressed. During this process, the sliding sleeve and the fixed sleeve slide together, and the corrugated sleeve expands and contracts synchronously. The corrugated sleeve can isolate external impurities from invading the interior of the shock absorber body, thereby protecting the shock absorber body. The sliding cooperation between the sliding sleeve and the fixed sleeve achieves the isolation of the corrugated sleeve from the shock absorber body on the basis of catering to the expansion and contraction trend of the shock absorber body and the corrugated sleeve, thereby avoiding the conflict between the corrugated sleeve and the spring lead-out movement due to the large deformation of the corrugated sleeve, thereby improving the stability of the shock absorber structure of the new energy vehicle.

[0015] 2. In this application, the two sets of mounting rings 1 are fixed to the sliding sleeve and the fixed sleeve respectively through two sets of locking rods, thereby ensuring the convenience of independent disassembly and assembly of the corrugated sleeve, and the two sets of mounting rings 2 are fixed to the outer ring and the cylinder ring respectively through two sets of fastening rods, thereby ensuring the convenience of disassembly and assembly of the sliding assembly and the shock absorber body, thereby improving the convenience of use of the shock absorber structure of new energy vehicles.

The outer wall of the sliding sleeve 10 is slidably connected to the inner wall of the fixed sleeve 11. A corrugated sleeve 5 is fixedly connected between the outer walls of the sliding sleeve 10 and the fixed sleeve 11.

[0025] As the new energy vehicle is running, the valve stem 102 slides with the sleeve 101 and the spring 103 is compressed. During this process, the sliding sleeve 10 slides with the fixed sleeve 11 while the bellows sleeve 5 expands and contracts synchronously. The bellows sleeve 5 can isolate external impurities from invading the interior of the shock absorber body 1, thereby protecting the shock absorber body 1. The sliding cooperation of the sliding sleeve 10 and the fixed sleeve 11, on the basis of catering to the expansion and contraction trend of the shock absorber body 1 and the bellows sleeve 5, realizes the isolation of the bellows sleeve 5 from the shock absorber body 1, avoids the bellows sleeve 5 from having a movement conflict with the spring 103 due to large local deformation, thereby improving the stability of the shock absorber structure of the new energy vehicle.
