[0002] Automotive hybrid power means adding a set of internal combustion engines to a pure electric vehicle, aiming to reduce vehicle pollution and increase the driving range of the pure electric vehicle. There are two structural forms of hybrid vehicles: series and parallel. Chassis bushings are used in the automotive hybrid chassis. Chassis bushings can improve the shock absorption ability of the vehicle. An automotive vulcanized bottom bushing is a bushing that tightly combines rubber and metal using a vulcanization process and is widely used in the automotive industry, especially in the suspension system. The vulcanization technology forms strong chemical bonds between the rubber and the metal, thus ensuring the high strength and high durability of the bushing.

[0003] However, the following problems exist in the use of existing automotive shock-absorbing vulcanized chassis bushings: During long-term use, the elastomer inside the bushing may be worn. The damage of the elastomer will cause the shock absorption ability of the bushing to decline, and it is necessary for the staff to replace the bushing. However, since the installation method of the bushing is generally relatively fixed, when the bushing needs to be disassembled, the staff often needs to use special disassembly tools to disassemble the bushing, and the operation is cumbersome. There is a lack of means to efficiently replace the damaged elastomer inside while retaining the bushing. Therefore, corresponding technical solutions need to be designed to solve the existing technical problems. Summary of the Invention

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-6 , the present invention provides a technical solution: a shock-absorbing vulcanized chassis bushing with hybrid power, including an outer shell 1, an inner bushing 2, an elastomer 3, a connecting piece 4 and a locking mechanism. An inner cavity 6 is formed inside the outer shell 1. The inner bushing 2 is located at the center of the inner cavity 6 and a filling cavity 7 is formed between the inner bushing 2 and the outer shell 1. The filling cavity 7 is filled with antifreeze ethylene glycol. Two groups of mounting openings 8 are symmetrically arranged at both ends of the inner bushing 2. Two groups of elastomers 3 are provided and symmetrically arranged at both ends of the filling cavity 7. The edges of the elastomers 3 are respectively in contact with the outer shell 1 and the inner bushing 2. The locking mechanism includes a locking ring one 9 and a locking ring two 10. The locking ring one 9 is sleeved on the end of the outer shell 1 and is in contact with the elastomer 3. The locking ring two 10 is sleeved on the end of the inner bushing 2 and is in contact with the elastomer 3. The connecting piece 4 includes a connecting rod 11 and a nut 12 threadedly fixed on the connecting rod 11. The connecting rod 11 penetrates through the mounting opening 8.

[0026] The first locking ring 9 includes an outer ring 14 with an annular docking cavity 13 formed by machining at the bottom and a first locking component 15 rotatably arranged inside the outer ring 14. A plurality of groups of adjustment openings 16 are evenly arranged on the inner ring of the annular docking cavity 13. The first locking component 15 includes a rotating ring 17, a convex block 18, an elastic connecting piece 19, and an arc-shaped pressing plate 20. A plurality of groups of convex blocks 18 are provided and evenly installed on the rotating ring 17. The plurality of groups of convex blocks 18 are correspondingly distributed in the adjustment openings 16 one by one. The elastic connecting piece 19 is located in the adjustment opening 16 and is connected to the arc-shaped pressing plate 20 on one side. A blade 21 is also fixed above the rotating ring 17, and a positioning bolt 22 is inserted through the blade 21. When it is necessary to fix the outer ring of the elastic body 3, the first locking ring 9 is clamped to the end of the housing 1 and the outer ring of the elastic body 3 is clamped. At this time, the staff can drive the rotating ring 17. During the rotation of the rotating ring 17, the convex block 18 is driven to rotate synchronously. The convex block 18 abuts against the elastic connecting piece 19 and abuts against the arc-shaped pressing plate 20 to move, and the outer ring of the elastic body 3 is clamped and fixed by the arc-shaped pressing plate 20. After the clamping is completed, the positioning bolt 22 is inserted into the corresponding concave hole 27 to achieve the purpose of positioning the rotating ring 17;

[0027] The second locking ring 10 includes an inner ring 24 with an annular docking cavity 23 formed by machining at the bottom and a second locking component 25 rotatably arranged outside the inner ring 24. A plurality of groups of movable openings 26 are evenly arranged on the outer ring of the annular docking cavity 13. The second locking component 25 has the same structure as the first locking component 15. In addition, a plurality of groups of concave holes 27 for using with the positioning bolt 22 are arranged on the inner side of the outer ring 14 and the outer side of the inner ring 24. The inner ring of the elastic body 3 can be limited and fixed by the second locking ring 10.

[0028] Further improved, as Figure 2 shown, the elastic body 3 is made of rubber material and has an overall annular structure. Convex rings 28 are formed on both the outer ring and the inner ring of the elastic body 3. The convex ring 28 located on the outer ring is used in cooperation with the first locking ring 9, and the convex ring 28 located on the inner ring is used in cooperation with the second locking ring 10.

[0029] Further improved, as Figure 2 shown, the surface of the elastic body 3 is formed into a laminated structure, and the outer ring and the inner ring are respectively in contact with the housing 1 and the inner shaft sleeve 2.

[0030] Further improved, as Figure 4 shown, the convex block 18 has a fan-shaped structure and the width of one end is smaller than that of the other end. The length of the convex block 18 is smaller than the width of the adjustment opening 16 and the width of the movable opening 26, which is convenient for the convex block 18 to displace in the adjustment opening 16.

[0031] Further improved, as Figure 6As shown, the elastic connecting piece 19 is made of an elastic material and its surface is processed into a laminated structure. The elastic connecting piece 19 is used in cooperation with the convex block 18 to facilitate deformation adjustment.

[0032] Further improved, as Figure 6 shown, the arc-shaped pressing plate 20 includes a contact plate 29 and several groups of engaging blocks 30 formed on the surface of the contact plate 29. The engaging blocks 30 are in a convex hemispherical structure. The arc-shaped pressing plate 20 moves inward and presses the elastic body 3 through the engaging blocks 30 to achieve the purpose of fixing the elastic body 3.

[0033] Specifically, the first locking ring 9 is clamped on the outer circle of the housing 1 and the elastic body 3, and the second locking ring 10 is clamped on the inner circle of the inner shaft sleeve 2 and the elastic body 3. The inner and outer circles of the elastic body 3 can be limited and fixed through the first locking ring 9 and the second locking ring 10.

[0034] During use: When the elastic body 3 is damaged during use, the staff pulls out the positioning bolt 22 outward, and then rotates the rotating ring 17. During the rotation of the rotating ring 17, the convex block 18 rotates synchronously and separates from the elastic connecting piece 19. At this time, the first locking ring 9 and the second locking ring 10 separate from the inner and outer circles of the elastic body 3, and the elastic body 3 can be quickly disassembled. After disassembly, a new elastic body 3 is replaced. When it is necessary to fix the outer circle of the elastic body 3, the first locking ring 9 is clamped at the end of the housing 1 and the outer circle of the elastic body 3 is clamped. At this time, the staff can drive the rotating ring 17. During the rotation of the rotating ring 17, the convex block 18 drives the convex block 18 to rotate synchronously. The convex block 18 abuts against the elastic connecting piece 19 and abuts against the arc-shaped pressing plate 20 to move. The outer circle of the elastic body 3 is clamped and fixed through the arc-shaped pressing plate 20. After clamping, the positioning bolt 22 is inserted into the corresponding concave hole 27 to achieve the purpose of positioning the rotating ring 17. The second locking ring 10 is fixed in the same way, thus achieving the purpose of quickly replacing the chassis bushing.
