Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and more specifically, to a shock absorption device and a scooter. Background Technology

[0002] In the current design of shock absorption systems for bicycles, motorcycles, and scooters, the synchronized rotation of the rocker arm and the shock absorber body is a key function, designed to improve the vehicle's performance on uneven surfaces, reduce vibration transmission, and enhance riding comfort.

[0003] In existing technologies, damping limiting technology typically uses separate limiting components to limit the rocker arm and damping inner cylinder in order to control their range of motion. However, the additional limiting components make the structure of the entire damping system more complex, increase assembly difficulty, and require additional space and cost. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a shock absorption device and a scooter.

[0005] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows:

[0006] A shock absorber includes: a blocking member having a blocking area; and a rocker arm member having a limiting area. The rocker arm member is oscillatingly disposed relative to the blocking member. The limiting area has a limiting state in which it engages with the blocking area to limit the extreme swing angle of the rocker arm member, and a non-limiting state in which it is separated from the blocking area and allows the rocker arm member to swing. In the above technical solution, by having the blocking member itself have a blocking area, the rocker arm member directly engages with the blocking member, i.e., the rocker arm member is limited by the blocking member to control the range of motion of the rocker arm member. This not only controls the upper limit of the wheel's travel but also limits the rotation angle of the inner cylinder. Thus, there is no need to set up separate limiting components to limit the rocker arm member and the inner cylinder of the shock absorber body, simplifying the structure of the entire shock absorber system, reducing assembly difficulty, and eliminating the need for additional space, thereby reducing production costs.

[0007] In some embodiments, the limiting region includes a limiting end face, and a portion of the end face of the rocker arm member facing the blocking member forms the limiting end face. When the rocker arm member swings, the limiting end face can abut against or move away from the blocking region. With the above configuration, when the rocker arm member swings due to the impact force of the road surface on the scooter, the limiting end face can abut against the blocking region, or move away from the blocking region under normal riding conditions of the scooter, thereby achieving effective control of the swing angle of the rocker arm member. In this way, the dynamic contact or separation between the limiting end face and the blocking region provides a boundary for the rocker arm member's movement, and also provides a rotation boundary for the inner cylinder of the shock absorber body, improving the response speed of the shock absorption system and the riding stability of the scooter.

[0008] In some embodiments, the distance between at least a portion of the limiting end face and the swing axis of the rocker arm member is greater than the distance between the blocking area and the swing axis; and / or, the rocker arm member has a projection plane, the projection plane is perpendicular to the swing axis of the rocker arm member, the limiting end face is projected onto the projection plane to form a projection line segment, the swing axis is projected onto the projection plane to form a swing center, and the length of the line connecting the projection line segment and the swing center gradually increases from bottom to top. With the above settings, when the scooter is subjected to road impact during riding, the swing arm component can make the limiting end face contact or separate from the blocking area to control the range of motion of the swing arm component. This not only controls the upper limit of the wheel's travel but also limits the rotation angle of the inner cylinder. Furthermore, by changing the length of the line connecting the limiting end face of the swing arm component to the swing center on the projection plane, the limiting end face can contact the blocking area in a softer and more gradual manner, rather than the sudden and rigid limiting in traditional solutions. This not only significantly reduces the peak impact force during collision and reduces structural damage that may be caused by excessive instantaneous torque, but also effectively extends the buffer time of the limiting action. This allows the entire shock absorption system to absorb energy more smoothly and efficiently when dealing with uneven road surfaces or sudden impacts, improving riding safety and comfort.

[0009] In some embodiments, the blocking member further has a non-contact area located below the blocking area. The limiting area also includes a clearance end face connected to the limiting end face. The clearance end face is correspondingly disposed to the non-contact area, and the distance between the clearance end face and the swing axis of the rocker arm member is less than the distance between the non-contact area and the swing axis. In the above technical solution, when the wheel encounters a large downward impact force, the end of the rocker arm member away from the blocking member swings downward accordingly. Due to its shorter vertical distance from the swing axis L, the clearance end face can avoid contact with the non-contact area of ​​the blocking member, giving the wheel a complete movement space, ensuring the maximization of the shock absorption stroke, thereby effectively absorbing and buffering external impacts, maintaining the stability of the vehicle body and the comfort of passengers.

[0010] In some embodiments, the avoidance end face is an arc surface, which is arranged around the swing axis of the rocker arm component; and / or, the limiting area also includes a transition end face, which is used to connect the limiting end face and the avoidance end face. In the above technical solution, the arc surface is easy to process, and when the rocker arm component swings and approaches the blocking component, the avoidance end face first maintains a safe distance from the non-contact area of ​​the blocking component, ensuring the degree of freedom of the lower limit of the wheel travel; as the swing angle further increases, the transition end face gradually intervenes in the interaction between the rocker arm component and the blocking component, and through gentle contact guidance, enables the limiting end face to form contact with the blocking area in a more gentle way, avoiding the abrupt limiting and hard collisions common in traditional limiting structures, and improving the stability and durability of the system.

[0011] In some embodiments, the blocking member includes a blocking body and a buffer portion connected to the blocking body, with the side of the buffer portion opposite to the blocking body forming a blocking area. In the above technical solution, by combining the blocking function and buffering effect in the same component, not only is the overall effectiveness of the limiting mechanism improved, but the user experience of the shock absorption system is also enhanced. The buffer portion, as the direct carrier of the blocking area, is made of a material with a certain degree of elasticity or deformability. It provides a flexible interface when the limiting end face of the rocker arm component contacts its blocking area, effectively buffering and absorbing the impact force generated by the collision. This greatly reduces the peak effect of this instantaneous force, avoiding structural damage or driving discomfort that may result from a hard collision.

[0012] In some embodiments, a buffer portion is stamped onto a portion of the blocking member, the buffer portion protruding relative to the blocking body towards the rocker arm member; or, the buffer portion is separately disposed from the blocking body, the buffer portion being located on the side of the blocking body facing the rocker arm member, and the buffer portion being made of an elastic material. This facilitates processing.

[0013] In some embodiments, there are two rocker arm components, and the shock absorption device further includes: a mounting bracket mounted on the blocking component; a shock absorption body; and a transmission component connected to the mounting bracket via the shock absorption body. The two rocker arm components are connected to both ends of the transmission component. In the above technical solution, the arrangement of dual rocker arm components, compared with a single component, can more effectively disperse and balance the transmitted force, reduce the burden of force on a single component, thereby significantly improving the system's ability to absorb and mitigate high-frequency vibrations and large impacts. Furthermore, the combination of the mounting bracket and the shock absorption body buffers the force transmitted between the rocker arm components and the transmission component through the elastic deformation characteristics of the shock absorption body. The transmission component, as a connecting bridge, ensures the synchronization between the movement of the rocker arm components and the energy absorption mechanism of the shock absorption body, enabling the entire shock absorption system to provide better shock absorption performance for the scooter when facing various road surface challenges.

[0014] In some embodiments, a reinforcing portion is stamped onto the rocker arm member; and / or, the damping device further includes an arc-shaped reinforcing member connected to the rocker arm member, with at least one of the upper and lower sides of the limiting region provided with the arc-shaped reinforcing member. In the above technical solution, by additionally providing an arc-shaped reinforcing member, the overall strength and rigidity of the rocker arm member can be improved. This not only effectively disperses concentrated stress acting on the rocker arm member, reducing the risk of fatigue cracks under high loads or impacts, but also enhances the rocker arm member's resistance to deformation, thereby improving its stability and reliability under dynamic loads.

[0015] In some embodiments, the rocker arm component includes: a rocker arm swayably disposed relative to the blocking component; and a stress dispersing component, which is provided on at least one side of the rocker arm along the swing axis of the rocker arm. The end faces of the rocker arm and the stress dispersing component facing the blocking component together form a limiting region. In the above technical solution, the rocker arm and the stress dispersing component together form an integrated limiting region facing the blocking component, which can increase the contact area between the limiting region and the blocking region. This allows the rocker arm to distribute the instantaneously generated force more evenly across the entire limiting region through its wider contact surface with the blocking component when it encounters an external impact, thereby avoiding local stress concentration. This not only effectively enhances the fatigue resistance and damage resistance of the contact area but also improves the limiting stability of the inner cylinder of the shock absorber body.

[0016] A scooter includes: a frame body; wheels; the aforementioned shock absorption device; a blocking member forming at least a portion of the rear frame plate, the rear frame plate being mounted on the frame body; and a rocker arm member being rotatably connected to the wheels.

[0017] In some embodiments, when the limiting area is in the limiting state, the frame body and the rocker arm component are arranged parallel to each other. This arrangement, with the frame body and rocker arm component in the limiting state, provides strong support for maintaining the stability of the vehicle under bumpy or sudden stopping conditions, offering the scooter a more stable riding posture and higher safety.

[0018] This utility model has the following beneficial effects: by making the blocking component itself have a blocking area, the rocker arm component can directly cooperate with the blocking component, that is, the rocker arm component is limited by the blocking component to control the range of motion of the rocker arm component. Thus, not only can the upper limit of the wheel's travel be controlled, but the rotation angle of the inner cylinder can also be limited. In this way, there is no need to set up a separate limiting component to limit the rocker arm component and the inner cylinder of the shock absorber body, which simplifies the structure of the entire shock absorber system, reduces the assembly difficulty, and does not require additional space, thereby reducing production costs.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0037] To address the problems of complex structure, additional space requirements, and high cost caused by the additional limiting components in existing shock-absorbing devices, this utility model provides a shock-absorbing device and a scooter.

[0038] In some embodiments, such as Figures 1 to 7 As shown, the scooter includes a frame body 1, wheels 2, and a shock absorption device. A blocking member 10 forms at least part of the rear plate of the frame, which is mounted on the frame body 1. A rocker arm member 20 is rotatably connected to the wheels 2. The rear plate of the frame is connected to the frame body 1 to form the frame.

[0039] The shock absorption device and the scooter will be explained in detail below.

[0040] In some embodiments, such as Figures 3 to 6 As shown, there are two rocker arm components 20. The shock absorption device also includes: a mounting bracket 40, which is installed on the blocking component 10; a shock absorption body 50; and a transmission component 60. The transmission component 60 is connected to the mounting bracket 40 through the shock absorption body 50. The two rocker arm components 20 are connected to both ends of the transmission component 60.

[0041] In the above technical solution, the dual rocker arm component 20, compared with a single component, can more effectively disperse and balance the transmitted force, reduce the burden of force on a single component, and thus greatly improve the system's ability to absorb and mitigate high-frequency vibrations and large impacts. Furthermore, the combination of the mounting frame 40 and the shock absorber body 50 uses the elastic deformation characteristics of the shock absorber body 50 to buffer the force transmitted between the rocker arm component 20 and the transmission component 60. The transmission component 60, as a connecting bridge, ensures the synchronization between the movement of the rocker arm component 20 and the energy absorption mechanism of the shock absorber body 50, so that the entire shock absorption system can provide better shock absorption performance for the scooter when dealing with various road surface challenges.

[0042] In some embodiments, the shock-absorbing body 50 includes an inner cylinder, an outer cylinder, and an elastic body. The inner cylinder is located on the outer periphery of the transmission member 60 and is connected to the transmission member 60; the outer cylinder is located on the outer periphery of the inner cylinder and is connected to the mounting bracket 40; an elastic body is provided between the inner cylinder and the outer cylinder, and the inner cylinder is connected to the outer cylinder through the elastic body.

[0043] With the above configuration, when the wheel 2 is subjected to vibration, the rocker arm component 20 can drive the inner cylinder to rotate via the transmission component 60, causing the inner cylinder to rotate relative to the outer cylinder via an elastic body. The use of an elastic body to connect the inner and outer cylinders achieves 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 can adjust the relative position between the inner and outer cylinders to adapt to different riding conditions, further optimizing the shock absorption effect.

[0044] In some embodiments, such as Figures 1 to 7 As shown, the damping device includes: a blocking member 10 having a blocking region 11; a rocker arm member 20 having a limiting region 21, the rocker arm member 20 being swingably disposed relative to the blocking member 10, the limiting region 21 having a limiting state that cooperates with the blocking region 11 to limit the extreme swing angle of the rocker arm member 20, and a non-limiting state that is separated from the blocking region 11 and allows the rocker arm member 20 to swing.

[0045] In the above technical solution, by making the blocking member 10 itself have a blocking area 11, the rocker arm member 20 can directly cooperate with the blocking member 10. That is, the rocker arm member 20 is limited by the blocking member 10 to control the range of motion of the rocker arm member 20. In this way, not only can the upper limit of the wheel's travel be controlled, but also the rotation angle of the inner cylinder can be limited. In this way, there is no need to set up a separate limiting component to limit the rocker arm member and the inner cylinder of the shock absorber body, which simplifies the structure of the entire shock absorber system, reduces the assembly difficulty, and does not require additional space, thereby reducing production costs.

[0046] Furthermore, in the limited state, the limiting area 21 cooperates with the blocking area 11 to limit the extreme swing angle of the rocker arm component 20; while in the non-limited state, the limiting area 21 separates from the blocking area 11, allowing the rocker arm component 20 to swing freely, thus not affecting the normal damping effect.

[0047] It should be noted that the extreme swing angle refers to Figure 2 The end of the rocker arm component 20 furthest from the wheel 2 swings downward to its limit position, and the end of the rocker arm component 20 connected to the wheel 2 swings upward to its limit position. At this time, the angle between the rocker arm component 20 and the horizontal direction controls the upper limit of the wheel's travel.

[0048] In some embodiments, the rocker arm component 20 is a sheet metal part.

[0049] In some embodiments, such as Figure 4 and Figure 5As shown, the limiting region 21 includes a limiting end face 211. The portion of the end face of the rocker arm member 20 facing the blocking member 10 forms the limiting end face 211. When the rocker arm member 20 swings, the limiting end face 211 can abut against or move away from the blocking region 11.

[0050] With the above settings, when the rocker arm component 20 swings due to the impact force of the road surface on the scooter, the limiting end face 211 can abut against the blocking area 11, or move away from the blocking area 11 under normal driving conditions of the scooter, thereby achieving effective control of the swing angle of the rocker arm component 20. In this way, the dynamic contact or separation between the limiting end face 211 and the blocking area 11 provides a boundary for the rocker arm component 20 to move, and also provides a boundary for the rotation of the inner cylinder of the shock absorber body 50, thereby improving the response speed of the shock absorber system and the stability of the scooter.

[0051] Of course, in another embodiment not shown, the limiting region 21 may also be a limiting protrusion that protrudes toward the blocking member 10.

[0052] In some embodiments, such as Figure 3 and Figure 4 As shown, at least part of the limiting end face 211 is at a distance from the swing axis L of the rocker arm component 20 to a distance greater than that between the blocking area 11 and the swing axis L.

[0053] With the above settings, when the scooter is in motion and is subjected to road impact, the rocker arm component 20 swings, which allows the limiting end face 211 to come into contact with or separate from the blocking area 11, thereby controlling the range of motion of the rocker arm component 20. This not only controls the upper limit of the wheel's travel but also limits the rotation angle of the inner cylinder.

[0054] In some embodiments, the limiting end face 211 can be a vertical surface. The distance between the limiting end face 211 and the swing axis L refers to the distance from the swing axis L along a direction perpendicular to the axis to the limiting end face 211. That is, the distance between the entire vertical surface and the swing axis L is constant. In other words, the distance between the entire limiting end face 211 and the swing axis L of the rocker arm member 20 is greater than the distance between the blocking area 11 and the swing axis L.

[0055] In some embodiments, the limiting end face 211 may also be an inclined surface. The distance between the limiting end face 211 and the swing axis L refers to the shortest distance from the swing axis L along a direction perpendicular to the axis to the nearest point of the limiting end face 211, which is also known as the minimum vertical distance. That is, the distance between the entire limiting end face 211 and the swing axis L of the rocker arm member 20 is greater than the distance between the blocking area 11 and the swing axis L.

[0056] In some embodiments, the distance between a portion of the limiting end face 211 and the swing axis L of the rocker arm member 20 may be greater than the distance between the blocking area 11 and the swing axis L.

[0057] In some embodiments, the blocking region 11 is provided with a blocking plane. When the limiting region 21 is in a limiting state, the limiting end face 211 is parallel to and abuts against the blocking plane.

[0058] In some embodiments, such as Figure 3 and Figure 4 As shown, the rocker arm component 20 has a projection plane, which is perpendicular to the swing axis L of the rocker arm component 20. The limiting end face 211 is projected onto the projection plane to form a projection line segment, and the swing axis L is projected onto the projection plane to form a swing center. The length of the line connecting the projection line segment and the swing center gradually increases from bottom to top.

[0059] In the above technical solution, by changing the length of the line connecting the limiting end face 211 of the rocker arm component 20 and the swing center on the projection plane, the limiting end face 211 can contact the blocking area 11 in a gentler and more gradual manner, rather than the sudden and rigid limiting in the traditional solution. This not only significantly reduces the peak impact force during collision and reduces the structural damage that may be caused by excessive instantaneous torque, but also effectively extends the buffer time of the limiting effect, so that the entire shock absorption system can absorb energy more smoothly and efficiently when dealing with uneven road surfaces or sudden impacts, thereby improving the safety and comfort of riding.

[0060] It should be noted that the up and down direction refers to... Figure 5 The vertical direction in the figure is the height direction of the scooter.

[0061] In some embodiments, such as Figure 2 and Figure 4 As shown, the blocking member 10 also has a non-contact area 12, which is located below the blocking area 11. The limiting area 21 also includes a clearance end face 212 connected to the limiting end face 211. The clearance end face 212 is correspondingly arranged with the non-contact area 12. The distance between the clearance end face 212 and the swing axis L of the rocker arm member 20 is less than the distance between the non-contact area 12 and the swing axis L.

[0062] In the above technical solution, when the wheel 2 encounters a large downward impact force, the end of the rocker arm component 20 away from the blocking component 10 swings downward accordingly. Due to its short vertical distance from the swing axis L, the avoidance end face 212 can avoid contact with the non-contact area 12 of the blocking component 10, giving the wheel 2 a complete movement space, ensuring the maximum shock absorption stroke, thereby effectively absorbing and buffering external impacts, maintaining the stability of the vehicle body and the comfort of passengers.

[0063] In some embodiments, such as Figure 4 As shown, the clearance end face 212 is an arc surface, which is arranged around the swing axis L of the rocker arm component 20. This facilitates processing, and the radius of the arc surface is smaller than the distance between the non-contact area 12 and the swing axis L, thus preventing the arc surface from contacting the non-contact area 12.

[0064] Of course, in another embodiment not shown, the avoidance end face 212 can also be an inclined surface, as long as it does not contact the blocking member 10.

[0065] In some embodiments, such as Figure 4 As shown, the limiting area 21 also includes a transition end face 213, which is used to connect the limiting end face 211 and the avoidance end face 212.

[0066] In the above technical solution, when the rocker arm component 20 swings and approaches the blocking component 10, the avoidance end face 212 first maintains a safe distance from the non-contact area 12 of the blocking component 10 to ensure the degree of freedom of the lower limit of the wheel travel; as the swing angle further increases, the transition end face 213 begins to gradually intervene in the interaction between the rocker arm component and the blocking component. Through gentle contact guidance, the limiting end face 211 can form contact with the blocking area 11 in a more gentle way, avoiding the abrupt limiting and hard collisions common in traditional limiting structures, and improving the stability and durability of the system.

[0067] In some embodiments, such as Figure 3 As shown, the blocking member 10 includes a blocking body 13 and a buffer portion 14 connected to the blocking body 13. The side of the buffer portion 14 facing away from the blocking body 13 forms a blocking area 11.

[0068] In the above technical solution, by combining the blocking function and the buffering effect in the same component, not only is the overall efficiency of the limiting mechanism improved, but the user experience of the shock absorption system is also enhanced. Among them, the buffer part 14, as the direct carrier of the blocking area 11, is made of a material with a certain elasticity or deformability. When the limiting end face 211 of the rocker arm component 20 comes into contact with its blocking area 11, it can provide a flexible interface, effectively buffering and absorbing the impact force generated by the collision, thereby greatly reducing the peak effect of this instantaneous force and avoiding structural damage or driving discomfort that may be caused by hard collisions.

[0069] In some embodiments, such as Figure 3 As shown, a portion of the blocking member 10 is stamped to form a buffer portion 14, which protrudes relative to the blocking body 13 toward the side where the rocker arm member 20 is located. This facilitates processing.

[0070] In some embodiments, such as Figure 3As shown, the blocking member 10 is made of sheet metal, and the buffer part 14 is formed by stamping on the sheet metal.

[0071] Of course, in another embodiment not shown, the buffer portion 14 and the blocking body 13 can also be provided separately, with the buffer portion 14 located on the side of the blocking body 13 facing the rocker arm member 20, and the buffer portion 14 being made of an elastic material. In this way, the buffering function can also be achieved.

[0072] In some embodiments, such as Figure 6 As shown, a reinforcing part 23 is stamped on the rocker arm component 20.

[0073] In the above technical solution, by changing the local cross-sectional shape of the rocker arm component 20, the overall strength and rigidity of the rocker arm component 20 can be improved. This not only effectively disperses the concentrated stress acting on the rocker arm component 20, reducing the risk of fatigue cracks under high loads or impacts, but also enhances the rocker arm component 20's ability to resist deformation, thereby improving its stability and reliability when subjected to dynamic loads.

[0074] In some embodiments, such as Figure 6 As shown, the shock absorption device also includes an arc-shaped reinforcing member 24 connected to the rocker arm member 20, and at least one of the upper and lower sides of the limiting area 21 is provided with the arc-shaped reinforcing member 24.

[0075] In the above technical solution, by additionally setting the arc-shaped reinforcing member 24, the overall strength and rigidity of the rocker arm component 20 can be improved. This can not only effectively disperse the concentrated stress acting on the rocker arm component 20 and reduce the risk of fatigue cracks under high load or impact, but also enhance the rocker arm component 20's ability to resist deformation, thereby improving its stability and reliability when subjected to dynamic loads.

[0076] The limiting components used in the prior art to limit the rocker arm components and shock absorber inner cylinder have a small contact area with the frame during operation. After fatigue, they are prone to shock absorber limiting failure, which seriously affects riding safety.

[0077] Therefore, in some embodiments, such as Figure 6 and Figure 7 As shown, the rocker arm component 20 includes: a rocker arm component 22, which is swayably disposed relative to the blocking component 10; and a stress dispersing component 25, which is disposed along the swing axis L of the rocker arm component 22. The stress dispersing component 25 is provided on at least one side of the rocker arm component 22, and the end faces of the rocker arm component 22 and the stress dispersing component 25 facing the blocking component 10 together form a limiting region 21.

[0078] In the above technical solution, the rocker arm 22 and the stress dispersing component 25 face one side of the blocking component 10 to form an integrated limiting area 21, which can increase the contact area between the limiting area 21 and the blocking area 11. In this way, when the rocker arm 20 encounters an external impact, it can distribute the instantaneously generated force more evenly to the entire limiting area 21 through its wider contact surface with the blocking component 10, thereby avoiding local stress concentration. This not only effectively enhances the fatigue resistance and damage resistance of the contact area, but also improves the limiting stability of the inner cylinder of the shock absorber body 50.

[0079] In some embodiments, when the limiting area 21 is in a limiting state, the frame body 1 and the rocker arm component 20 are arranged in parallel.

[0080] Through the above settings, the parallel relationship between the frame body 1 and the rocker arm component 20 in the limited state provides strong support for maintaining the stability of the vehicle under bumpy or sudden stop conditions, and provides the scooter with a more stable riding posture and higher safety.

[0081] It should be noted that in some embodiments, after the wheel 2 receives an impact force from the ground, the rocker arm component 20 drives the wheel 2 to rotate around the center of the outer cylinder of the shock absorber body 50. At this time, the rocker arm component 20 rotates to be close to the rear plate of the frame, the shock absorption stroke is reached, and the limiting action begins. At this time, the rocker arm component 20 and the rear plate of the frame are subjected to compressive forces from both sides. The compressive forces are evenly distributed on the limiting area 21, the force value per unit area is reduced, and the strength is increased.

[0082] This utility model has at least the following beneficial effects: by making the blocking component itself have a blocking area, the rocker arm component can directly cooperate with the blocking component, that is, the rocker arm component is limited by the blocking component to control the range of motion of the rocker arm component. Thus, not only can the upper limit of the wheel's travel be controlled, but the rotation angle of the inner cylinder can also be limited. In this way, there is no need to set up a separate limiting component to limit the rocker arm component and the inner cylinder of the shock absorber body, which simplifies the structure of the entire shock absorber system, reduces the assembly difficulty, and does not require additional space, thereby reducing production costs.
