Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of shock absorption, in particular to a shock absorption assembly and a scooter. BACKGROUND

[0002] In the current shock absorption system design of portable scooter tools such as bicycles, motorcycles and scooters, synchronous rotation of the rocker arm and the shock absorption body is a key function, aiming to improve the riding performance of the vehicle on uneven road surfaces, reduce vibration transmission and improve riding comfort.

[0003] However, in the prior art, multiple locking members are usually used to connect the shock absorption cylinder and the rocker arm to achieve synchronous rotation of the shock absorption cylinder and the rocker arm. This requires multiple alignment and multiple fastening during assembly, which can cause problems such as difficulty in assembling the shock absorption assembly. SUMMARY

[0004] Therefore, the utility model aims to provide a shock absorption assembly and a scooter.

[0005] To achieve the above-mentioned purpose, the technical scheme provided by an embodiment of the utility model is as follows:

[0006] A shock absorption assembly includes a shock absorption body, a rocker arm member connected to at least one side of the shock absorption body, the rocker arm member including a rocker arm and a bushing, the shock absorption body and the rocker arm being rotationally fixed to the bushing, and a locking member passing through the bushing and locking the rocker arm member to the shock absorption body. In this way, compared with the prior art in which multiple locking members are used to connect the shock absorption cylinder and the rocker arm, in the present application, the shock absorption body and the rocker arm are rotationally fixed to the bushing, which can achieve the pre-positioning of the rocker arm and the bushing, and the pre-positioning of the shock absorption body and the bushing. In this way, the rocker arm can be installed on the bushing in a pre-positioned manner to form a rocker arm member, and the rocker arm member can be installed on the shock absorption body in a pre-positioned manner, and the rocker arm member can be locked to the shock absorption body by the locking member. In this way, during assembly, multiple alignment and multiple fastening are not required, thereby reducing the assembly difficulty of the shock absorption assembly and facilitating the assembly of the shock absorption assembly. Moreover, by providing the bushing and the locking member, synchronous rotation of the shock absorption body and the rocker arm can be achieved without the need for multiple locking members, thereby reducing the processing cost.

[0007] In some embodiments, the shock absorption body and the rocker arm are located on the outer periphery of the bushing. In this way, one shock absorption body can simultaneously absorb the shock of two rocker arms. Correspondingly, the vehicle has two wheels, and the two wheels are connected to the two rocker arms. The wheels can be rear wheels or front wheels.

[0008] In some embodiments, the bushing kit includes: an annular limiting portion located on the side of the rocker arm away from the shock absorber body, and a locking member pressing the rocker arm against the shock absorber body via the annular limiting portion; and an anti-rotation cylinder connected to the annular limiting portion, the anti-rotation cylinder passing through the rocker arm and the shock absorber body, with both the rocker arm and the shock absorber body engaging with the anti-rotation cylinder. With the above arrangement, the annular limiting portion is located on the side of the rocker arm away from the shock absorber body. Through the locking action of the locking member, the annular limiting portion can press the rocker arm against the shock absorber body, thus ensuring a fixed connection between the rocker arm and the shock absorber body, effectively preventing loosening caused by vibration or impact during vehicle operation, and improving the overall reliability of the system. The anti-rotation cylinder forms an anti-rotation engagement with the rocker arm and the shock absorber body. The rocker arm can drive the inner cylinder to rotate through the anti-rotation cylinder, causing the inner cylinder to rotate relative to the outer cylinder via an elastic body. Thus, during vehicle operation, it can effectively absorb and buffer vibrations caused by uneven road surfaces or impacts, significantly improving riding comfort and safety.

[0009] In some embodiments, the anti-rotation cylinder is a square cylinder, the rocker arm has a first square hole, and the shock absorber body has a second square hole. The anti-rotation cylinder passes through the first square hole and the second square hole in sequence. The anti-rotation cylinder engages with the rocker arm through the first square hole to prevent rotation, and the shock absorber body engages with the anti-rotation cylinder through the second square hole. Alternatively, the rocker arm has a first through hole, and the shock absorber body has a second through hole. The shock absorber assembly also includes a limiting key and a limiting groove that engages with the limiting key. The outer wall of the anti-rotation cylinder has one of the limiting key and the limiting groove, and the inner walls of both the first and second through holes have the other of the limiting key and the limiting groove. This allows for synchronous rotation of the rocker arm and the shock absorber body. Furthermore, it allows for pre-positioning of the rocker arm with the bushing and pre-positioning of the shock absorber body with the bushing, thereby simplifying the assembly process and reducing assembly difficulty and time.

[0010] In some embodiments, the rocker arm and the bushing are interference-fitted; and / or, the shock absorber body and the bushing are interference-fitted. This allows for the connection between the rocker arm and the bushing; and / or between the shock absorber body and the bushing, thus ensuring wheel stability under high loads or severe vibrations and reducing safety risks during riding.

[0011] In some embodiments, there are two rocker arm components, each located on one side of the shock absorber body. The locking component includes: a first anti-detachment part located on the side of one of the rocker arm components facing away from the shock absorber body; a locking body; and a second anti-detachment part located on the side of the other rocker arm component facing away from the shock absorber body. One end of the locking body is connected to the first anti-detachment part, and the other end of the locking body passes through the shock absorber body and the two rocker arm components and is connected to the second anti-detachment part. With this configuration, the first and second anti-detachment parts can respectively press the two rocker arm components tightly against the shock absorber body, thereby preventing axial movement of the shock absorber body and the rocker arm components, and preventing the two rocker arm components from detaching from the locking body, thus ensuring the stability of the wheel under high loads or severe vibrations.

[0012] In some embodiments, the shock absorber assembly further includes a mounting portion connected to the outer periphery of the shock absorber body and connected to the vehicle body. This allows the shock absorber assembly to be mounted on the vehicle body.

[0013] In some embodiments, the mounting portion includes a bracket and a cylindrical structure connected to the bracket. The cylindrical structure has an internal through-hole, and the shock absorber body is interference-fitted with the internal through-hole. The bracket is connected to the vehicle body. In the above technical solution, by using an interference fit to connect the shock absorber body and the mounting portion, the number of connecting parts can be reduced, thereby reducing the structural complexity of the shock absorber assembly and thus reducing the assembly difficulty.

[0014] In some embodiments, the shock-absorbing body includes: an inner cylinder located on the outer periphery of the bushing and anti-rotationally engaged with the bushing; an outer cylinder located on the outer periphery of the inner cylinder; and an elastic body disposed between the inner and outer cylinders, with the inner cylinder connected to the outer cylinder via the elastic body. With this configuration, when the wheel is subjected to vibration, the rocker arm can drive the inner cylinder to rotate via the bushing, causing the inner cylinder to rotate relative to the outer cylinder via the elastic body. The use of the elastic body to connect the inner and outer cylinders achieves an elastic connection between them, effectively absorbing and buffering vibrations caused by uneven road surfaces or impacts during vehicle operation, significantly improving riding comfort and safety. Furthermore, the elastic body can adjust the relative position between the inner and outer cylinders to adapt to different riding conditions, further optimizing the shock absorption effect.

[0015] In some embodiments, a reinforcing portion is stamped onto the rocker arm; and / or, an arc-shaped reinforcing member is provided on the rocker arm, the arc-shaped reinforcing member being bent towards the direction of the damping body. This improves the overall strength and rigidity of the rocker arm, effectively dispersing concentrated stresses acting on it, reducing the risk of fatigue cracks under high loads or impacts, and enhancing its resistance to deformation, thereby improving its stability and reliability under dynamic loads.

[0016] A personal mobility vehicle includes: a body; wheels; and the aforementioned shock-absorbing assembly, wherein the shock-absorbing body is disposed on the body and the rocker arm is connected to the wheels.

[0017] This utility model has the following advantages: Compared with the prior art that uses multiple locking parts to connect the shock absorber and the rocker arm, in this application, the shock absorber body and the rocker arm are respectively anti-rotationally engaged with the bushing, which can achieve pre-positioning of the rocker arm and the bushing, and pre-positioning of the shock absorber body and the bushing. In this way, the rocker arm can be first installed on the bushing to form a rocker arm component by pre-positioning, and then the rocker arm component can be installed on the shock absorber body by pre-positioning, and the rocker arm component can be locked on the shock absorber body by locking parts. In this way, multiple alignments and tightenings are not required during the assembly process, thereby reducing the assembly difficulty of the shock absorber assembly and facilitating the assembly of the shock absorber assembly; and by setting the bushing and locking parts, the synchronous rotation of the shock absorber body and the rocker arm can be achieved, eliminating the need for multiple locking parts and reducing processing costs.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0035] To address the problem of inconvenient assembly caused by the need for multiple alignments and lockings during the assembly process of existing shock-absorbing components, this utility model provides a shock-absorbing component and a mobility scooter.

[0036] In some embodiments, such as Figures 1 to 6 As shown, the mobility scooter includes: a body 1, wheels 2 and shock absorption components. The shock absorption body 10 is mounted on the body 1, and the rocker arm 21 is connected to the wheels 2.

[0037] The shock absorption components and the mobility scooter will be explained in detail below.

[0038] In some embodiments, such as Figures 1 to 6 As shown, the damping assembly includes: a damping body 10; a rocker arm component 20, at least one side of the damping body 10 is connected to the rocker arm component 20, the rocker arm component 20 includes a rocker arm 21 and a bushing 22, the damping body 10 and the rocker arm 21 respectively engage with the bushing 22 to prevent rotation; and a locking component 30, which passes through the bushing 22 and locks the rocker arm component 20 onto the damping body 10.

[0039] In the above technical solution, compared with the prior art which uses multiple locking components to connect the shock absorber and the rocker arm, in this application, the shock absorber body 10 and the rocker arm 21 are respectively anti-rotationally engaged with the bushing 22, which can achieve pre-positioning of the rocker arm 21 and the bushing 22, and pre-positioning of the shock absorber body 10 and the bushing 22. In this way, the rocker arm 21 can be pre-positioned and installed on the bushing 22 to form the rocker arm component 20, and then the rocker arm component 20 can be pre-positioned and installed on the shock absorber body 10. The locking component 30 is used to lock the rocker arm component 20 on the shock absorber body 10. In this way, multiple alignments and tightenings are not required during the assembly process, thereby reducing the assembly difficulty of the shock absorber assembly and facilitating the assembly of the shock absorber assembly. Moreover, by setting the bushing 22 and the locking component 30, the synchronous rotation of the shock absorber body 10 and the rocker arm 21 can be achieved, eliminating the need for multiple locking components and reducing processing costs.

[0040] In some embodiments, such as Figure 4 As shown, there is only one locking component 30. This avoids the need to disassemble and assemble multiple locking components, thereby further simplifying the disassembly and assembly process of the shock absorption assembly.

[0041] In some embodiments, the rocker arm 21 is made of sheet metal.

[0042] It should be noted that the shock absorption components can be used in personal mobility vehicles, which can be bicycles, electric scooters, or electric bicycles, etc.

[0043] In some embodiments, such as Figure 4 and Figure 5 As shown, the shock-absorbing body 10 includes an inner cylinder 11, an outer cylinder 12, and an elastic body 13. The inner cylinder 11 is located on the outer periphery of the bushing 22 and is anti-rotationally engaged with the bushing 22; the outer cylinder 12 is located on the outer periphery of the inner cylinder 11; the elastic body 13 is provided between the inner cylinder 11 and the outer cylinder 12, and the inner cylinder 11 is connected to the outer cylinder 12 through the elastic body 13.

[0044] With the above configuration, when the wheel 2 is subjected to vibration, the rocker arm 21 can drive the inner cylinder 11 to rotate via the bushing 22, causing the inner cylinder 11 to rotate relative to the outer cylinder 12 via the elastic body 13. The elastic body 13 connects the inner cylinder 11 and the outer cylinder 12, achieving an elastic connection between them. During vehicle operation, this effectively absorbs and buffers vibrations caused by uneven road surfaces or impacts, significantly improving riding comfort and safety. Furthermore, the elastic body 13 can adjust the relative position between the inner cylinder 11 and the outer cylinder 12 to adapt to different riding conditions, further optimizing the shock absorption effect.

[0045] In some embodiments, the elastomer 13 may be made of any of the following materials: rubber, polyurethane, and thermoplastic elastomer (TPE).

[0046] In some embodiments, the inner cylinder 11 and the outer cylinder 12 are made of metal materials, wherein the inner cylinder 11 can be a profile, which facilitates subsequent processing.

[0047] In some embodiments, such as Figure 4 and Figure 5 As shown, there are two rocker arm components 20, located on opposite sides of the damping body 10. This allows one damping body 10 to simultaneously dampen both rocker arm components 21. Correspondingly, there are also two wheels 2, each connected to one of the two rocker arm components 21. These wheels can be either rear wheels or front wheels.

[0048] Of course, in another embodiment not shown, only one rocker arm component 20 may be provided.

[0049] In some embodiments, such as Figure 4 As shown, both the damping body 10 and the rocker arm 21 are located on the outer periphery of the bushing 22. This simplifies the structure of the bushing 22, facilitates the positioning of the rocker arm 21 on the outer periphery of the bushing 22, and also facilitates the positioning and installation of the rocker arm 20 within the damping body 10.

[0050] Of course, in another embodiment not shown, the rocker arm 21 is disposed on the outer periphery of the bushing 22 and engages with the bushing 22 to prevent rotation. The inner cylinder 11 includes two connecting cylinder sections and a main cylinder section for connecting the two connecting cylinder sections. The outer diameter of each connecting cylinder section is smaller than the outer diameter of the main cylinder section, so that the two connecting cylinder sections can be inserted into the interior of the two bushings 22 respectively and engage with the bushings 22 to prevent rotation. In this way, the synchronous rotation of the shock-absorbing body 10 and the rocker arm 21 can also be achieved.

[0051] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the bushing assembly 22 includes an annular limiting part 221 and an anti-rotation cylinder 222. The annular limiting part 221 is located on the side of the rocker arm 21 away from the damping body 10, and the locking member 30 presses the rocker arm 21 against the damping body 10 through the annular limiting part 221. The anti-rotation cylinder 222 is connected to the annular limiting part 221, and the anti-rotation cylinder 222 passes through the rocker arm 21 and the damping body 10, and both the rocker arm 21 and the damping body 10 are anti-rotatingly engaged with the anti-rotation cylinder 222.

[0052] With the above configuration, the annular limiting part 221 is located on the side of the rocker arm 21 away from the shock absorber body 10. Through the locking action of the locking member 30, the annular limiting part 221 can press the rocker arm 21 onto the shock absorber body 10. This ensures the fixed connection between the rocker arm 21 and the shock absorber body 10, effectively preventing loosening caused by vibration or impact during vehicle operation, and improving the overall reliability of the system. The anti-rotation cylinder 222 forms an anti-rotation fit with the rocker arm 21 and the shock absorber body 10. The rocker arm 21 can drive the inner cylinder 11 to rotate through the anti-rotation cylinder 222, so that the inner cylinder 11 rotates relative to the outer cylinder 12 through the elastic body 13. In this way, during vehicle operation, it can effectively absorb and buffer the vibration caused by uneven road surface or impact, significantly improving the riding comfort and safety.

[0053] Of course, in another embodiment not shown, the liner 22 may not include the annular limiting part, and may only include the anti-rotation cylinder 222.

[0054] In some embodiments, such as Figure 5 As shown, the annular limiting part 221 can be an annular limiting plate.

[0055] Of course, in another embodiment not shown, the annular limiting part 221 may also be a plurality of plate segments arranged circumferentially along the anti-rotation cylinder 222, each plate segment being connected to the anti-rotation cylinder 222.

[0056] In some embodiments, such as Figure 5 As shown, the anti-rotation cylinder 222 is a square cylinder. The rocker arm 21 has a first square hole, and the shock absorber body 10 has a second square hole. The anti-rotation cylinder 222 is inserted through the first square hole and the second square hole in sequence. The anti-rotation cylinder 222 is engaged with the rocker arm 21 through the first square hole to prevent rotation, and the shock absorber body 10 is engaged with the anti-rotation cylinder 222 through the second square hole.

[0057] With the above configuration, when the square tube is inserted into the first square hole and the second square hole, the square tube can form a firm anti-rotation fit with the rocker arm 21 and the shock absorber body 10 respectively, so as to realize the synchronous rotation of the rocker arm 21 and the shock absorber body 10. In addition, by adopting this square fit, the rocker arm 21 and the bushing 22 can be pre-positioned, and the shock absorber body 10 and the bushing 22 can be pre-positioned, thereby simplifying the assembly process, reducing assembly difficulty and time. Moreover, in long-term use, the square structure is more resistant to wear than the circular structure, maintains the accuracy of the connection, extends the service life of the shock absorber system and the rocker arm, and reduces maintenance costs.

[0058] Furthermore, the above structure is easy to process and can also reduce processing costs.

[0059] In some embodiments, such as Figure 5 As shown, the inner cylinder 11 has the aforementioned second square hole inside.

[0060] Of course, in another embodiment not shown, the anti-rotation cylinder 222 can also be a hexagonal cylinder, with a hexagonal hole on the rocker arm 21 and a hexagonal hole on the shock-absorbing body 10, and the hexagonal cylinder is inserted into two hexagonal holes; or, the anti-rotation cylinder 222 can also be an octagonal cylinder, with an octagonal hole on the rocker arm 21 and an octagonal hole on the shock-absorbing body 10.

[0061] In some embodiments, such as Figure 6 As shown, the rocker arm 21 is provided with a first through hole, the shock absorber body 10 is provided with a second through hole, the shock absorber assembly also includes a limit key 223 and a limit groove 224 that cooperates with the limit key 223 for limiting, the outer wall of the anti-rotation cylinder 222 is provided with a limit groove 224, and the inner wall of the first through hole and the inner wall of the second through hole are both provided with limit keys 223.

[0062] With the above configuration, the rocker arm 21 has a first through hole and the shock absorber body 10 has a second through hole. The first and second through holes allow the anti-rotation cylinder 222 to pass through them, forming a basic connecting frame. The outer wall of the anti-rotation cylinder 222 has a limiting groove 224, and the inner walls of the first and second through holes are both provided with limiting keys 223. When the anti-rotation cylinder 222 is inserted into the two holes, the limiting key 223 will be embedded in the limiting groove 224, forming an anti-rotation fit. This not only enables the rocker arm 21 and the shock absorber body 10 to rotate synchronously, but also enables the rocker arm 21 to be pre-positioned with the bushing 22 and the shock absorber body 10 to be pre-positioned with the bushing 22. This simplifies the assembly process and reduces assembly difficulty and time.

[0063] Of course, in another embodiment not shown, the outer wall of the anti-rotation cylinder 222 is provided with a limiting key 223, and the inner wall of the first through hole and the inner wall of the second through hole are both provided with limiting grooves 224.

[0064] In some embodiments, such as Figure 5 As shown, the inner cylinder 11 has the aforementioned second through hole inside.

[0065] In some embodiments, the rocker arm 21 is interference-fitted with the bushing 22; and / or, the shock absorber body 10 is interference-fitted with the bushing 22. This allows for the connection between the rocker arm 21 and the bushing 22; and / or between the shock absorber body 10 and the bushing 22, thus ensuring the stability of the wheel 2 under high loads or severe vibrations and reducing safety risks during riding.

[0066] Furthermore, the rocker arm 21 and the bushing 22 are interference-fitted, so that the symmetry of the two rocker arm 21 can be improved after the locking member 30 is locked.

[0067] In some embodiments, such as Figure 2, Figure 4 and Figure 5 As shown, the locking member 30 includes a first anti-detachment part 32, a locking body 31, and a second anti-detachment part 33. The first anti-detachment part 32 is located on the side of one of the two rocker arm members 20 facing away from the shock-absorbing body 10; the second anti-detachment part 33 is located on the side of the other rocker arm member 20 facing away from the shock-absorbing body 10. One end of the locking body 31 is connected to the first anti-detachment part 32, and the other end of the locking body 31 passes through the shock-absorbing body 10 and the two rocker arm members 20 before connecting to the second anti-detachment part 33.

[0068] With the above configuration, the first anti-detachment part 32 and the second anti-detachment part 33 can press the two rocker arm components 20 onto the shock absorber body 10 respectively, thereby preventing the shock absorber body 10 and the rocker arm components 20 from axial movement, and also preventing the two rocker arm components 20 from coming off the locking body 31, thus ensuring the stability of the wheel 2 when subjected to high loads or severe vibrations.

[0069] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the outer diameter of the first anti-detachment part 32 and the outer diameter of the second anti-detachment part 33 are both larger than the outer diameter of the locking body 31.

[0070] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the first anti-detachment part 32 is integrally formed with the locking body 31, and the second anti-detachment part 33 is detachably connected with the locking body 31. Specifically, the first anti-detachment part 32 and the locking body 31 are integrally formed as a bolt, and the second anti-detachment part 33 is a nut; or, in another embodiment not shown, the first anti-detachment part 32 and the locking body 31 are integrally formed as a pin, and the second anti-detachment part 33 is a cotter pin.

[0071] Of course, in another embodiment not shown, the first anti-detachment part 32, the locking body 31 and the second anti-detachment part 33 are separately provided, that is, the first anti-detachment part 32 and the second anti-detachment part 33 are both detachably connected to the locking body 31. The first anti-detachment part 32 is a nut, the locking body 31 is a connecting shaft, both ends of the connecting shaft are provided with threads, the second anti-detachment part 33 is a nut, and the first anti-detachment part 32 and the second anti-detachment part 33 are both threadedly connected to the connecting shaft.

[0072] Of course, in another embodiment not shown, the first anti-detachment part 32, the locking body 31 and the second anti-detachment part 33 are integrally formed, that is, the locking member 30 is a rivet.

[0073] In some embodiments, such as Figure 1 and Figure 2As shown, the shock absorber assembly also includes a mounting part 40, which is connected to the outer periphery of the shock absorber body 10 and connected to the vehicle body 1. In this way, the shock absorber assembly can be mounted on the vehicle body 1.

[0074] In some embodiments, the mounting part 40 may be mounted on the vehicle body 1 by welding or by bolting.

[0075] In some embodiments, such as Figure 2 and Figure 4 As shown, the mounting part 40 includes a bracket 41 and a cylindrical structure 42 connected to the bracket 41. The cylindrical structure 42 has an internal through hole. The shock absorber body 10 is interference-fitted with the internal through hole. The bracket 41 is connected to the vehicle body 1.

[0076] In the above technical solution, by using an interference fit to connect the damping body 10 and the mounting part 40, the number of connecting parts can be reduced, thereby reducing the structural complexity of the damping assembly and thus reducing the assembly difficulty.

[0077] In some embodiments, such as Figure 4 As shown, the outer cylinder 12 of the shock-absorbing body 10 is interference-fitted with the internal through hole of the cylindrical structure 42.

[0078] Of course, in another embodiment not shown, the mounting part 40 may also include a bracket and two mounting plates connected to the bracket. The two mounting plates are spaced apart along the axial direction of the damping body 10, and each mounting plate is provided with a mounting through hole, which is interference-fitted with the damping body 10.

[0079] In some embodiments, such as Figure 2 As shown, a reinforcing part 23 is stamped on the rocker arm 21.

[0080] In the above technical solution, by changing the local cross-sectional shape of the rocker arm 21 or increasing the material thickness, the overall strength and rigidity of the rocker arm 21 can be improved. This not only effectively disperses the concentrated stress acting on the rocker arm 21 and reduces the risk of fatigue cracks under high loads or impacts, but also enhances the rocker arm 21's ability to resist deformation, thereby improving its stability and reliability when subjected to dynamic loads.

[0081] In some embodiments, such as Figure 2 As shown, the rocker arm 21 is provided with an arc-shaped reinforcing member 24, which bends toward the direction of the shock-absorbing body 10.

[0082] In the above technical solution, by additionally setting the arc-shaped reinforcing member 24, the overall strength and rigidity of the rocker arm member 21 can be improved. This can not only effectively disperse the concentrated stress acting on the rocker arm member 21 and reduce the risk of fatigue cracks under high load or impact, but also enhance the rocker arm member 21's ability to resist deformation, thereby improving its stability and reliability when subjected to dynamic loads.

[0083] Existing shock absorber components suffer from asymmetry due to manufacturing errors, leading to wheel twisting after installation, which can cause disc rubbing and affect riding posture. This application, however, improves symmetry through structural optimization, reducing wheel twisting caused by manufacturing errors.

[0084] This utility model has at least the following beneficial effects: Compared with the prior art that uses multiple locking parts to connect the shock absorber and the rocker arm, in this application, the shock absorber body 10 and the rocker arm 21 are respectively anti-rotationally engaged with the bushing 22, which can achieve the pre-positioning of the rocker arm 21 and the bushing 22, and the pre-positioning of the shock absorber body 10 and the bushing 22. In this way, the rocker arm 21 can be pre-positioned and installed on the bushing 22 to form the rocker arm component 20, and then the rocker arm component 20 can be pre-positioned and installed on the shock absorber body 10. The locking part 30 is used to lock the rocker arm component 20 on the shock absorber body 10. In this way, multiple alignments and tightenings are not required during the assembly process, thereby reducing the assembly difficulty of the shock absorber assembly and facilitating the assembly of the shock absorber assembly. Moreover, by setting the bushing 22 and the locking part 30, the synchronous rotation of the shock absorber body 10 and the rocker arm 21 can be achieved, eliminating the need for multiple locking parts and reducing processing costs.

[0085] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0086] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
