[0002] Shock absorbers are key components of vehicles, serving not only to provide support but also to improve ride smoothness and thus enhance driving comfort. However, in some technologies, shock absorbers occupy a significant amount of space in the direction intersecting their axial direction (i.e., the damping direction), which is unfavorable for their placement.

[0022] Optionally, the movable structure has a contact portion adapted to contact the rotating member, so that the rotating member can push the movable structure through the contact portion during rotation.

[0023] Optionally, the movable structure further includes a movable frame having the contact portion, the contact portion including an upper contact member and a lower contact member connected together, the upper contact member and the lower contact member being disposed opposite to each other along the first direction, and the rotating member being located between the upper contact member and the lower contact member, so that the rotating member can push the upper contact member or the lower contact member during rotation.

[0024] The first end of the moving shaft is connected to the moving frame, and the second end of the moving shaft is used to connect to the component to be damped.

[0025] Optionally, the rotating component is a cam, and the cross-section of the cam is a Reichstag polygon, so that the outer peripheral surface of the rotating component always remains in contact with the upper contact component and the lower contact component during rotation.

[0026] Optionally, the shock absorber further includes a rotating shaft, the driving component is throttle-connected to the rotating shaft, and the rotating component is sleeved on the rotating shaft;

[0027] A guide groove extending along the first direction is formed on the movable frame, and one end of the rotating shaft passes through the guide groove.

[0028] According to a second aspect of this disclosure, a vehicle suspension is provided, including the shock absorber as described above.

[0029] According to a third aspect of this disclosure, a vehicle is provided, including the vehicle suspension described above.

[0030] Optionally, the vehicle further includes a body and wheels, the shock absorber includes a shock absorber mounting base, the shock absorber mounting base is mounted on the body, and the moving shaft of the moving structure of the shock absorber is connected to the wheels.

[0031] Through the above technical solution, since the rotating component can rotate and drive the moving structure to move along the first direction, by reasonably adjusting the rotation direction and / or rotation angle of the rotating component, the moving structure can be driven to move in the first direction in the opposite direction to the vibration direction of the component to be damped. In this way, the vibration of the component to be damped is reduced or canceled by the movement of the moving structure of the damper, thereby achieving damping.

[0032] Furthermore, in the shock absorber provided in this disclosure, the rotating component can drive the moving structure to move along the first direction when it rotates. That is, the rotating component and the moving structure cooperate through mechanical transmission. Compared with hydraulic shock absorbers and air spring shock absorbers in related technologies, on the one hand, the mechanical transmission type shock absorber provided in this disclosure has a faster response speed, and on the other hand, it can reduce the airtightness requirements (hydraulic shock absorbers and air spring shock absorbers have high requirements for the sealing of the medium), reduce the difficulty of production and manufacturing, and reduce manufacturing and maintenance costs.

[0033] Furthermore, since the rotating component in the shock absorber provided in this disclosure drives the moving structure to move in the first direction by rotating, the rotational motion of the rotating component is converted into the linear motion of the moving structure. Under the condition of meeting the moving stroke requirements of the moving structure, the space required by the rotating component in the first direction is small, which is conducive to reducing the size of the overall structure of the shock absorber in the first direction and facilitating the arrangement of the shock absorber.

[0034] Through the above technical solution, since the rotating component can rotate and drive the moving structure to move along the first direction, by reasonably adjusting the rotation direction and / or rotation angle of the rotating component, the moving structure can be driven to move in the first direction in the opposite direction to the vibration direction of the component to be damped. In this way, the vibration of the component to be damped is reduced or canceled by the movement of the moving structure of the damper, thereby achieving damping.

[0035] Furthermore, in the shock absorber provided in this disclosure, the rotating component can drive the moving structure to move along the first direction when it rotates. That is, the rotating component and the moving structure cooperate through mechanical transmission. Compared with hydraulic shock absorbers and air spring shock absorbers in related technologies, on the one hand, the mechanical transmission type shock absorber provided in this disclosure has a faster response speed, and on the other hand, it can reduce the airtightness requirements (hydraulic shock absorbers and air spring shock absorbers have high requirements for the sealing of the medium), reduce the difficulty of production and manufacturing, and reduce manufacturing and maintenance costs.

[0036] Secondly, since the rotating component drives the moving structure to move in the first direction by rotating in the shock absorber provided in this disclosure, the rotational motion of the rotating component is converted into the linear motion of the moving structure. Under the condition of meeting the moving stroke requirements of the moving structure, the space required by the rotating component in the first direction is small, which is conducive to reducing the size of the overall structure of the shock absorber in the first direction and facilitating the arrangement of the shock absorber.

[0037] Furthermore, since the axis of the output shaft of the drive component intersects the axis of rotation of the rotating component, and the axis of the output shaft of the drive component is set parallel to the axis of the moving shaft (i.e., the output shaft of the drive component extends along the first direction), the above-mentioned shock absorber can be set on one side of the moving structure in the first direction by reasonably designing the positions of the drive component, the rotating component and the moving structure. This is beneficial to reduce the space occupied by the drive component in other directions that intersect with the first direction, thereby facilitating the arrangement of the shock absorber.

Detailed Implementation

[0056] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0057] In this disclosure, unless otherwise stated, directional terms such as "first direction" indicate directions or positional relationships defined based on the map directions shown in the corresponding accompanying drawings. Figures 1 to 14 The illustrations shown are for illustrative purposes only and to simplify the description of this disclosure, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational construction and operation, and therefore should not be construed as a limitation of this disclosure. It is understood that the "first direction" can be a direction parallel or substantially parallel to the vibration direction of the component to be damped. For the application scenario of the shock absorber provided in this disclosure in the vehicle field (i.e., the shock absorber is a vehicle shock absorber), the "first direction" can be the vertical direction under normal vehicle driving conditions.

[0058] The terms "inner" and "outer" refer to the inner and outer contours of the corresponding structures. Additionally, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0059] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0060] like Figures 1 to 14 As shown, this disclosure provides a shock absorber 100, which includes a rotating member 2 and a movable structure 3. The movable structure 3 is coupled to the rotating member 2, and the rotating member 2 can rotate and drive the movable structure 3 to move along a first direction.

[0061] Understandably, the movable structure 3 is adapted to connect with the component to be damped in order to reduce or eliminate the vibration impact of the component.

[0062] It should be noted that the shock absorber 100 provided in this disclosure can be applied to any suitable application scenario with shock absorption requirements. For example, the shock absorber 100 can be applied to vehicles to absorb the impact of bumps and potholes on the road surface; or, the shock absorber 100 can be applied to aircraft landing gear to absorb the impact of landing; or, the shock absorber 100 can be applied to mining machinery and equipment, sports equipment, etc. This disclosure does not limit it.

[0063] The aforementioned shock absorber refers to the component whose vibration effect needs to be reduced or eliminated. For example, in the application scenario where the shock absorber 100 is a vehicle shock absorber, the shock absorber can be the vehicle body or the wheel. The moving structure 3 of the shock absorber 100 can be connected to the vehicle body or the wheel (for example, the moving structure 3 can be connected to the wheel through the axle or directly to the wheel).

[0064] Through the above technical solution, since the rotating component 2 can rotate and drive the moving structure 3 to move along the first direction, by reasonably adjusting the rotation direction and / or rotation angle of the rotating component 2, the moving structure 3 can be driven to move in the first direction in the opposite direction to the vibration direction of the component to be damped. In this way, the vibration of the component to be damped is reduced or canceled by the movement of the moving structure 3 of the shock absorber 100, thereby achieving shock absorption.

[0065] For example, when the shock absorber 100 is applied to a vehicle, if the vehicle is subjected to an impact from the road surface, causing the vehicle to vibrate, by reasonably adjusting the rotation direction and / or rotation angle of the rotating component 2, the moving structure 3 can be driven to move in the first direction in the opposite direction to the vehicle vibration direction. In this way, the movement of the moving structure 3 of the shock absorber 100 reduces or offsets the impact of the road surface, thereby achieving vehicle shock absorption.

[0066] Furthermore, in the shock absorber 100 provided in this disclosure, when the rotating component 2 rotates, it can drive the moving structure 3 to move along the first direction. That is, the rotating component 2 and the moving structure 3 cooperate through mechanical transmission. Compared with hydraulic shock absorbers and air spring shock absorbers in related technologies, on the one hand, the mechanical transmission type shock absorber 100 provided in this disclosure has a faster response speed, and on the other hand, it can reduce the airtightness requirements (hydraulic shock absorbers and air spring shock absorbers have high requirements for the sealing of the medium), reduce the difficulty of production and manufacturing, and reduce manufacturing and maintenance costs.

[0067] Furthermore, since the rotating member 2 drives the moving structure 3 to move in the first direction by rotating in the shock absorber 100 provided in this disclosure, the rotational motion of the rotating member 2 is converted into the linear motion of the moving structure 3. Under the condition of meeting the moving stroke requirements of the moving structure 3, the space required by the rotating member 2 in the first direction is small, which is conducive to reducing the size of the overall structure of the shock absorber 100 in the first direction and facilitating the arrangement of the shock absorber 100.

[0068] The aforementioned rotating member 2 rotating and driving the moving structure 3 to move in the first direction can be either a unidirectional movement of the moving structure 3 in the first direction or a reciprocating movement in the first direction; this disclosure does not limit this. Furthermore, regarding the case where the rotating member 2 rotating and driving the moving structure 3 to reciprocate in the first direction, it can be that the rotating member 2 rotates in one direction while driving the moving structure 3 to reciprocate in the first direction, or it can be that the rotating member 2 rotates in different directions while driving the moving structure 3 to reciprocate in the first direction; this disclosure does not limit this.

[0069] In one embodiment of this disclosure, the rotating member 2 can drive the moving structure 3 to reciprocate in a first direction when rotating in one direction. In other words, the rotating member 2 does not need to repeatedly change its rotation direction; it only needs to rotate in one direction to drive the moving structure 3 to reciprocate, thereby achieving shock absorption and simplifying the control of the shock absorber 100.

[0070] It should be noted that the reciprocating movement of the above-mentioned moving structure 3 refers to the moving structure 3 moving back and forth in the first direction. That is, in the first position and the second position with an interval in the first direction, the moving structure 3 can move from the first position to the second position, or from the second position to the first position.

[0071] To drive the rotating component 2 to rotate, optionally, as follows: Figures 1-3 , Figures 7-9 , Figure 11 As shown, the shock absorber 100 also includes a driving component 1, which is connected to and drives the rotating component 2 to rotate. Thus, by driving the rotating component 2 to rotate, the driving component 1 can indirectly drive the moving structure 3 to move along the first direction, thereby achieving the shock absorption effect of the shock absorber 100. It can be understood that the driving component 1 can directly drive the rotating component 2 to rotate, for example, by mounting the rotating component 2 on the output shaft of the driving component 1; or the driving component 1 can indirectly drive the rotating component 2 to rotate, for example, by driving the rotating component 2 to rotate through a transmission mechanism 9.

[0072] This disclosure does not limit the specific type of the drive element 1. Optionally, the drive element 1 may be constructed as a rotary motor 11.

[0073] Optionally, the shock absorber 100 may further include a rotating shaft 6, with the rotating component 2 being drivenly connected to the rotating shaft 6 (for example, the rotating component 2 may be mounted on the rotating shaft 6), and the driving component 1 being drivenly connected to the rotating shaft 6. In other words, the driving component 1 can be connected to the rotating component 2 via the rotating shaft 6, thereby driving the rotating shaft 6 to rotate, which in turn drives the rotating component 2 to rotate.

[0074] like Figure 6 and Figure 7As shown, in one embodiment provided in this disclosure, the shock absorber 100 includes a driving member 1, a rotating member 2, and a moving structure 3. The moving structure 3 is coupled to the rotating member 2. The axis of the output shaft of the driving member 1 intersects the rotation axis of the rotating member 2. The driving member 1 and the rotating member 2 are connected in a transmission manner so that the rotating member 2 rotates and drives the moving structure 3 to move along a first direction. The moving structure 3 includes a moving shaft 33, which extends along the first direction and is adapted to be connected to the component to be damped. The axis of the output shaft of the driving member 1 is arranged parallel to the axis of the moving shaft 33.

[0075] Furthermore, since the axis of the output shaft of the drive member 1 intersects the axis of rotation of the rotating member 2, and the axis of the output shaft of the drive member 1 is parallel to the axis of the moving shaft 33 (i.e., the output shaft of the drive member 1 extends along the first direction), the shock absorber 100 can be arranged on one side of the moving structure 3 in the first direction by reasonably designing the positions of the drive member 1, the rotating member 2 and the moving structure 3. This is beneficial to reduce the space occupied by the drive member 1 in other directions that intersect with the first direction, thereby facilitating the arrangement of the shock absorber 100.

[0076] For example, when the shock absorber 100 is applied to a vehicle, the moving shaft 33 extends along the vertical direction of the vehicle, and the drive member 1 is disposed on one side of the moving structure 3 in the vertical direction. Even if the space for other directions (e.g., the horizontal direction) intersecting the vertical direction of the vehicle is small, the shock absorber 100 can still be disposed in the vehicle.

[0077] Optionally, the intersection of the output shaft axis of the drive member 1 and the rotation axis of the rotating member 2 can be such that the output shaft axis of the drive member 1 is perpendicular to the rotation axis of the rotating member 2. Alternatively, the output shaft axis of the drive member 1 and the rotation axis of the rotating member 2 can form an acute or obtuse angle.

[0078] This disclosure does not limit the specific position between the driving component 1 and the moving structure 3. As one embodiment of this disclosure, such as Figure 6 and Figure 7 As shown, the output shaft of the drive unit 1 is coaxially arranged with the moving shaft 33, that is, the axis of the output shaft of the drive unit 1 coincides with the axis of the moving shaft 33.

[0079] This disclosure does not limit the specific positional relationship between the driving member 1 and the moving structure 3. As one embodiment of this disclosure, the driving member 1 and the moving structure 3 are spaced apart in the first direction. Thus, there is space between the driving member 1 and the moving structure 3 for arranging the rotating member 2, and a transmission mechanism 9, such as a reversing transmission mechanism 92 or a reduction transmission mechanism 91, can also be arranged in this space.

[0080] Optionally, such as Figure 6 and Figure 7As shown, in the case where the shock absorber 100 includes a rotating shaft 6 and the rotating member 2 is mounted on the rotating shaft 6, the axis of the output shaft of the drive member 1 intersects the axis of the rotating shaft 6. Specifically, the axis of the output shaft of the drive member 1 is perpendicular to the axis of the rotating shaft 6.

[0081] like Figures 8 to 10 As shown, in one embodiment provided in this disclosure, the shock absorber 100 includes a driving member 1, a rotating member 2, and a moving structure 3. The moving structure 3 is coupled to the rotating member 2. The axis of the output shaft of the driving member 1 is parallel to the axis of rotation of the rotating member 2. The driving member 1 and the rotating member 2 are connected in a transmission manner so that the driving member 1 can drive the rotating member 2 to rotate and drive the moving structure 3 to move along a first direction. The moving structure 3 includes a moving shaft 33, which extends along the first direction and is adapted to be connected to the component to be damped. The axis of the output shaft of the driving member 1 intersects the axis of the moving shaft 33.

[0082] Since the axis of the output shaft of the drive component 1 is parallel to the axis of rotation of the rotating component 2, and the axis of the output shaft of the drive component 1 intersects the axis of the moving shaft 33, by reasonably designing the positions of the drive component 1, the rotating component 2 and the moving structure 3, the drive component 1 can be set on one side of the moving structure 3 along other directions that intersect with the first direction. That is, the drive component 1 and the moving structure 3 are not arranged along the first direction. This is beneficial to reduce the space occupied by the drive component 1 in the first direction, facilitates the arrangement of the shock absorber 100, and is beneficial to increase the stroke range of the shock absorber (i.e., the movement range of the moving structure).

[0083] For example, when the shock absorber 100 is applied to a vehicle, the moving shaft 33 extends along the vertical direction of the vehicle. Even if the space in the vertical direction of the vehicle is small, the arrangement space in other directions (such as the horizontal direction) that intersect with the vertical direction is large, so the shock absorber 100 can still be arranged in the vehicle.

[0084] Optionally, such as Figure 8 and Figure 9 As shown, the axis of the output shaft of the drive member 1 can be perpendicular to the axis of the moving shaft 33. In other words, the drive member 1 can be located on one side of the moving shaft 33 along its radial direction, so that the overall space occupied by the shock absorber 100 in the first direction is smaller, which is beneficial to the arrangement of the shock absorber 100.

[0085] Optionally, the drive member 1 is spaced apart from the moving shaft 33 in the radial direction. In this way, the rotating member 2 can be arranged in the space between the drive member 1 and the moving shaft 33, and a transmission mechanism 9, such as a reduction transmission mechanism 91 or a gear transmission mechanism 93, can also be arranged in this space.

[0086] For an embodiment of the shock absorber 100 including the rotating shaft 6, optionally, as Figures 8 to 10As shown, the axis of the output shaft of the drive component 1 is parallel to the axis of the rotating shaft 6. The drive component 1 is connected to the rotating shaft 6 in a transmission connection, and the rotating shaft 6 is connected to the rotating component 2 in a transmission connection.

[0087] Optionally, such as Figures 8 to 10 As shown, the axis of rotation 6 is perpendicular to the axis of movement 33.

[0088] Optionally, such as Figures 8 to 10 As shown, the axis of the output shaft of the drive component 1 and the axis of the rotating shaft 6 are both perpendicular to the first direction, and the output shaft of the drive component 1 and the rotating shaft 6 are spaced apart along the first direction. A transmission mechanism 9 can be arranged in the space between the output shaft of the drive component 1 and the rotating shaft 6, and the drive component 1 can be connected to the rotating shaft 6 through the transmission mechanism 9. The transmission mechanism 9 can be a reduction transmission mechanism 91 or a gear transmission mechanism 93.

[0089] This disclosure does not limit the specific shape of the rotating member 2, as long as the rotating member 2 can drive the moving structure 3 to move in the first direction when rotating. As one embodiment of this disclosure, such as... Figures 1 to 11 As shown, the distance between the outline edge of the rotating component 2 and the rotation center of the rotating component 2 in the first direction changes as the rotating component 2 rotates. In other words, during the rotation of the rotating component 2, the distance between the outline edge of the rotating component 2 and the rotation center of the rotating component 2 along the first direction is constantly changing, thereby enabling the rotating component 2 to drive the moving structure 3 to move along the first direction when it rotates.

[0090] It is understood that the outline edge of the rotating component 2 and the rotation center of the rotating component 2 have two distances in the first direction. The change of the distance between the outline edge of the rotating component 2 and the rotation center of the rotating component 2 in the first direction as the rotating component 2 rotates may be that at least one of the two distances between the outline edge of the rotating component 2 and the rotation center of the rotating component 2 in the first direction changes.

[0091] This disclosure does not limit the specific type of the rotating component 2. As one embodiment of this disclosure, such as Figures 1 to 10 As shown, the rotating component 2 can be constructed as a cam 21.

[0092] Optionally, the cam 21 can be a disc cam, a cylindrical cam, etc., and this disclosure does not limit it.

[0093] As another embodiment provided in this disclosure, the rotating member 2 can be constructed as a disk.

[0094] In the embodiment where the rotating member 2 is constructed as a disk, the center of rotation of the disk is eccentrically positioned relative to the center of the disk, so that the distance between the edge of the disk's outline and the center of rotation in the first direction is constantly changing. In other words, the center of rotation of the disk does not coincide with the center of the disk. Thus, during the rotation of the disk, the distance between the center of rotation of the disk and the edge of the disk's outline in the first direction can continuously change, thereby driving the moving structure 3 to move in the first direction.

[0095] In an embodiment where the rotating component 2 is configured as a cam 21, the rotation center of the cam 21 may coincide with the center of the base circle of the cam 21 and / or the geometric center of the cam 21, or the rotation center of the cam 21 may not coincide with the center of the base circle of the cam 21 and / or the assembly center of the cam 21.

[0096] As one embodiment of this disclosure, such as Figure 4 , Figure 5 , Figure 9 as well as Figure 10 As shown, the rotation center of cam 21 is eccentrically set relative to the center of the base circle of cam 21 and / or the geometric center of cam 21. Because the rotation center of cam 21 is eccentrically set relative to the base circle of cam 21 and / or the geometric center of cam 21, during the rotation of cam 21, the difference between the maximum and minimum distances between the rotation center of cam 21 and the contour edge of cam 21 along the first direction increases, resulting in cam 21 having a larger push stroke and a smaller return stroke. Thus, during the rotation of cam 21, the range of distances that cam 21 can drive the moving structure 3 to move along the first direction increases, and the shock absorber 100 can have a larger damping range.

[0097] Optionally, the maximum distance L from the profile edge of cam 21 to the rotation center of cam 21 Max The minimum distance L from the profile edge of cam 21 to the rotation center of cam 21 Min The ratio satisfies 1 < L Max / L Min ≤4. Because the difference between the maximum and minimum distances between the rotation center of cam 21 and the profile edge of cam 21 along the first direction is large, cam 21 has a large push stroke and a small return stroke.

[0098] Furthermore, due to the maximum distance L Max minimum distance L Min The ratio satisfies L Max / L Min ≤4, in other words, the maximum distance L Max minimum distance L MinWith a distance less than or equal to four times the minimum distance, the cam 21 can increase the damping range of the shock absorber 100 while avoiding the situation where the size of the cam 21 is too large due to the damping range of the shock absorber 100 being too large (e.g., far exceeding the damping range required by the vehicle), resulting in the shock absorber 100 being too large and thus inconvenient to arrange.

[0099] This disclosure does not limit the specific transmission relationship between the rotating member 2 and the moving structure 3. As one embodiment provided by this disclosure, the moving structure 3 has a contact portion 34, which is adapted to contact the rotating member 2 so that the rotating member 2 can push the moving structure 3 through the contact portion 34 during rotation. In other words, the contour edge of the rotating member 2 can contact the contact portion 34 of the moving structure 3 during rotation, so that the moving structure 3 can move along a first direction under the pushing action of the contour edge of the rotating member 2 during rotation.

[0100] It should be noted that the rotating part 2 may be in contact with the contact part 34 at all times during the rotation process, or it may be in contact with the contact part 34 at certain times during the rotation process. This disclosure does not limit this.

[0101] Optionally, such as Figures 1 to 14 As shown, the movable structure 3 may include a movable frame 31, the movable frame 31 having a contact portion 34, the contact portion 34 including an upper contact member 311 and a lower contact member 312 connected together, the upper contact member 311 and the lower contact member 312 being arranged opposite to each other along a first direction, and the rotating member 2 being located between the upper contact member 311 and the lower contact member 312, so that the rotating member 2 can push the upper contact member 311 or the lower contact member 312 during rotation.

[0102] Since the contact portion 34 includes an upper contact member 311 and a lower contact member 312 disposed opposite to each other along the first direction, and the rotating member 2 can push the upper contact member 311 or the lower contact member 312 during rotation, in other words, during the rotation of the rotating member 2, the outline edge of the rotating member 2 can contact at least one of the upper contact member 311 and the lower contact member 312. Thus, even if the rotating member 2 always rotates in one direction, the upper contact member 311 and / or the lower contact member 312 can contact the outline edge of the rotating member 2, thereby realizing the reciprocating movement of the moving structure 3 along the first direction.

[0103] To further improve the damping effect of the shock absorber 100, as one embodiment of this disclosure, the rotating member 2 is configured such that its contour edge remains in contact with the upper contact member 311 and the lower contact member 312 throughout rotation. Because the contour edge of the rotating member 2 remains in contact with the upper contact member 311 and the lower contact member 312 throughout rotation, collisions do not occur between the always-contacting upper contact member 311, lower contact member 312, and rotating member 2, and the shock absorber 100 itself does not vibrate. This improves the damping effect of the shock absorber 100 and also prevents collisions between the upper contact member 311, lower contact member 312, and rotating member 2, which could easily lead to damage to one or more of them.

[0104] In order to ensure that the rotating member 2 remains in contact with the upper contact member 311 and the lower contact member 312 of the moving structure 3 during rotation, optionally, as follows: Figure 4 , Figure 5 , Figure 9 as well as Figure 10 As shown, the rotating component 2 is a cam 21, and the cross-section of the cam 21 is a Reichstag polygon.

[0105] It should be noted that a Leno polygon is a curve of constant width, where the distance from its centroid (i.e., the geometric center of the cross section) to any point on its contour edge is equal. In other words, a Leno polygon has the same width in any direction.

[0106] Since the Leno polygon has the same width in any direction, by reasonably setting the distance between the upper contact 311 and the lower contact 312 that are positioned opposite each other along the first direction, the cam 21 with a cross-section formed as a Leno polygon can always maintain contact with the upper contact 311 and the lower contact 312 during rotation.

[0107] This disclosure does not limit the specific type of Leno polygon; as one implementation of this disclosure, such as Figure 4 , Figure 5 , Figure 9 as well as Figure 10 As shown, the cross-section of the aforementioned cam 21 can be formed as a Reichstag triangle.

[0108] For the embodiment where the movable structure 3 includes a movable frame 31, the movable frame 31 has a contact portion 34, and the contact portion 34 includes a connected upper contact member 311 and a lower contact member 312, in order to further improve the damping effect of the shock absorber 100, optionally, in a first direction, there is a first distance between the upper contact member 311 and the lower contact member 312, and in the first direction, there is a second distance between the contact point between the rotating member 2 and the upper contact member 311 and the contact point between the rotating member 2 and the lower contact member 312, wherein the first distance is equal to the second distance. In other words, the distance between the two contact points of the rotating part 2 that contact the upper contact part 311 and the lower contact part 312 is equal to the distance between the upper contact part 311 and the lower contact part 312. In this way, by reasonably designing the shape of the rotating part 2, the outline edge of the rotating part 2 can always maintain contact with the upper contact part 311 and the lower contact part 312 during rotation. The upper contact part 311, the lower contact part 312 and the rotating part 2 that are always in contact will not collide, and the shock absorber 100 itself will not vibrate. On the one hand, the shock absorption effect of the shock absorber 100 is improved, and on the other hand, it also avoids the situation where the upper contact part 311, the lower contact part 312 and the rotating part 2 collide with each other, which would easily lead to the damage of one or more of the upper contact part 311, the lower contact part 312 and the rotating part 2.

[0109] like Figures 1-13 , Figure 4 , Figures 6 to 11 as well as Figure 14 As shown, in an embodiment where the movable structure 3 also includes a movable shaft 33 connected to the component to be damped, the first end of the movable shaft 33 can be connected to the movable frame 31, and the second end of the movable shaft 33 is used to connect to the component to be damped. In other embodiments, the lower contact member 312 can also be connected to the component to be damped.

[0110] To facilitate the connection of the movable shaft 33 to the component to be damped, in one embodiment of this disclosure, the lower end of the movable shaft 33 is provided with a connecting portion for connecting to the component to be damped. In other words, the movable shaft 33 can be connected to the component to be damped via the connecting portion, making the connection between the movable shaft 33 and the component to be damped relatively simple.

[0111] Optionally, a fork 321 is provided at the end of the movable shaft 33 away from the rotating member 2. The fork 321 is used to connect with the component to be damped, and the connection part includes the fork 321. In the application scenario where the shock absorber 100 is used in a vehicle, the fork 321 can facilitate the connection of the movable shaft 33 to the wheel or axle.

[0112] To further improve the damping effect of the shock absorber 100, optionally, such as Figure 3 , Figure 4 as well as Figures 6 to 11As shown, the shock absorber 100 also includes an elastic element 4, which is sleeved on the movable shaft 33. Because the elastic element 4 is sleeved on the movable shaft 33, it can absorb the impact of vibrations, thus improving the shock absorption effect of the shock absorber 100. For example, when the shock absorber 100 is applied to a vehicle, the elastic element 4 can absorb the impact of the road surface, thereby improving the shock absorption effect of the shock absorber 100.

[0113] It should be noted that this disclosure does not limit the specific type of the elastic element 4. As one embodiment of this disclosure, the elastic element 4 is configured as a spring. As other embodiments, the elastic element 4 can also be an elastic sleeve, etc.

[0114] In order for the elastic element 4 to absorb the impact of vibration, thereby improving the damping effect of the shock absorber 100, optionally, as... Figure 3 , Figure 4 as well as Figures 6 to 11 As shown, one end of the elastic element 4 abuts against the housing 30 or the movable frame 31, and the other end of the elastic element 4 abuts against the connecting part (e.g., the fork 321). In other words, the elastic element 4 abuts between the housing 30 (or the movable frame 31) and the connecting part. When the shock absorber 100 is vibrated, causing the connecting part to move towards the rotating member 2, the housing 30 (or the movable frame 31) and the connecting part together compress the elastic element 4. The elastic force of the elastic element 4 reacts to the housing 30 (or the movable frame 31) and the connecting part, thereby absorbing the impact of the vibration to a certain extent.

[0115] When the shock absorber 100 is vibrated and the connecting shaft moves away from the rotating part 2, the housing 30 and the connecting part together stretch the elastic element 4. The elastic force of the elastic element 4 can also react on the housing 30 and the connecting part, thereby absorbing the impact of the vibration to a certain extent.

[0116] Here, it can be understood that, in the embodiment where the movable shaft 33 is provided with a fork 321 at the end away from the rotating member 2, and the fork 321 is used to connect with the component to be damped, one end of the elastic member 4 abuts against the housing 30, and the other end of the elastic member 4 abuts against the fork 321.

[0117] To guide the movement of the moving structure 3 in the first direction, optionally, as follows: Figure 5 and Figure 14 As shown, the shock absorber 100 also includes a guide structure 5, which guides the movement of the movable structure 3 in the first direction. Thus, during the rotation of the rotating member 2, the movable structure 3 does not rotate with the rotating member 2, but is able to move along the first direction under the combined action of the rotating member 2 and the guide structure 5, thereby achieving shock absorption.

[0118] This disclosure does not limit the specific structure of the guide structure 5. As one embodiment of this disclosure, such as Figure 5 and Figure 14 As shown, the movable structure 3 includes a movable frame 31, the rotating member 2 is located inside the movable frame 31 and can push the movable frame 31 to move along the first direction during rotation, the movable frame 31 has a guide groove 51 extending along the first direction, the shock absorber 100 also includes a rotating shaft 6, the rotating member 2 is sleeved on the rotating shaft 6, one end of the rotating shaft 6 passes through the guide groove 51 and is connected to the driving member 1, and the guide structure 5 includes the guide groove 51.

[0119] Since the rotating shaft 6 passes through the guide groove 51, one end of the rotating shaft 6 is connected to the driving member 1, and the other end of the rotating shaft 6 is connected to the rotating member 2. The side wall of the guide groove 51 can cooperate with the rotating shaft 6. During the rotation of the rotating shaft 6, the guide groove 51 of the moving frame 31 moves relative to the rotating shaft 6 in the first direction, thereby ensuring that the moving structure 3 moves in the first direction. This effectively avoids the situation where the moving structure 3 rotates with the rotating member 2 and the shock absorber 100 cannot dampen the vibration.

[0120] As another implementation of this disclosure, such as Figures 9 to 11 As shown, the shock absorber also includes a housing 30, and the guide structure 5 includes the housing 30. A portion of the moving structure 3 (e.g., the upper part of the moving structure 3) contacts two side walls of the housing 30 opposite each other in a second direction. The second direction is perpendicular to the first direction. The two side walls are used to guide the movement of the moving structure 3 in the first direction.

[0121] In other words, the upper part of the movable structure 3 is clamped between the two side walls of the housing 30. The two side walls of the housing 30 can limit the movable structure 3 in the second direction. During the rotation of the rotating shaft 6, the movable structure 3 can only move back and forth in the first direction, effectively preventing the movable structure 3 from rotating with the rotating part 2 and the shock absorber 100 from failing to dampen the vibration.

[0122] Optionally, such as Figures 9 to 11 As shown, in an embodiment where the movable structure 3 includes a movable frame 31, the movable frame 31 can contact two sidewalls of the housing 30 that are opposite each other in the second direction.

[0123] In another embodiment of this disclosure, the housing 30 may also be provided with a guide groove 51 extending in the first direction, and one end of the rotating shaft 6 passes through the guide groove 51. In this way, the guide groove 51 can also guide the moving structure 3.

[0124] To facilitate the installation of the shock absorber 100, optionally, such as Figures 1-3 , Figure 4 , Figure 6 as well as Figure 7As shown, the shock absorber 100 also includes a shock absorber mounting base 7, which is adapted to mount the drive component 1. The shock absorber mounting base 7 can install and fix the shock absorber 100, and can effectively prevent the shock absorber 100 from shaking.

[0125] Furthermore, since the shock absorber mounting base 7 is suitable for mounting the drive component 1, in other words, the shock absorber mounting base 7 can be used to fix both the shock absorber 100 and the drive component 1. The drive component 1 can be fixed without setting a separate fixing structure, which helps to simplify the structure of the entire shock absorber 100 and reduce the size of the shock absorber 100.

[0126] In order to transmit the power of the driving member 1 to the rotating member 2, as one embodiment of this disclosure, the shock absorber 100 further includes a transmission mechanism 9 and a rotating shaft 6. The rotating member 2 is sleeved on the rotating shaft 6, and the driving member 1 is connected to the rotating shaft 6 via the transmission mechanism 9. The transmission mechanism 9 and the rotating shaft 6 can transmit the power of the driving member 1, thereby enabling the driving member 1 to drive the rotating member 2 to rotate via the transmission mechanism 9 and the rotating shaft 6, and in turn drive the moving structure 3 to move, so as to realize the shock absorption of the shock absorber 100.

[0127] To increase the torque of the rotating component 2, the transmission mechanism 9 may optionally include a reduction transmission mechanism 91. The reduction transmission mechanism 91 can reduce the speed and increase the torque of the driving component 1. Only a driving component 1 with a smaller output torque is needed to drive the rotating component 2 to rotate. This is beneficial for saving the cost of the driving component 1 and also for saving the space occupied by the driving component 1 in the shock absorber 100.

[0128] Optionally, in embodiments where the shock absorber 100 includes a housing 30, one or more of the aforementioned transmission mechanism 9 (e.g., reduction transmission mechanism 91, reversing transmission mechanism 92, gear transmission mechanism 93) and drive member 1 may be disposed within the housing 30.

[0129] The speed reduction transmission mechanism 91 can be a worm gear reducer, a planetary gear reducer, a gear reducer, etc., and this disclosure does not limit it.

[0130] Optionally, such as Figure 7 and Figure 8 As shown, the shock absorber 100 may further include a gear transmission mechanism 93, through which the drive member 1 is connected to the rotating shaft 6. The gear transmission mechanism 93 connects the drive member 1 and the rotating shaft 6, thereby driving the rotating shaft 6 to rotate.

[0131] Here, it can be understood that, in the embodiment where the shock absorber 100 also includes a transmission mechanism 9 and a rotating shaft 6, and the rotating member 2 is sleeved on the rotating shaft 6, the transmission mechanism 9 may include a gear transmission mechanism 93. The driving member 1 is connected to the rotating shaft 6 via the gear transmission mechanism 93. The gear transmission mechanism 93 and the rotating shaft 6 can transmit power to the driving member 1, thereby enabling the driving member 1 to drive the rotating member 2 to rotate via the gear transmission mechanism 93 and the rotating shaft 6, and in turn drive the moving structure 3 to move, so as to achieve the shock absorption of the shock absorber 100.

[0132] Optionally, the transmission ratio of the aforementioned gear transmission mechanism 93 is greater than 1. Since the transmission ratio of the gear transmission mechanism 93 is greater than 1, the output speed of the gear transmission mechanism 93 is less than its input speed, and the output torque of the gear transmission mechanism 93 is greater than its input torque. Therefore, the gear transmission mechanism 93 is configured as a reduction transmission mechanism 91. The reduction transmission mechanism 91 can reduce the speed and increase the torque of the driving component 1. Only a driving component 1 with a smaller output torque is needed to drive the rotating component 2. This helps save on the cost of the driving component 1 and also saves the space occupied by the driving component 1 within the shock absorber 100.

[0133] For embodiments of the shock absorber 100 that include a gear transmission mechanism 93 or a reduction transmission mechanism 91, optionally, as Figure 7 and Figure 8 As shown, the gear transmission mechanism 93 or the reduction transmission mechanism 91 includes a first gear 911 and a second gear 912 that mesh with each other. The first gear 911 is mounted on the output shaft of the drive member 1, and the second gear 912 is mounted on the rotating shaft 6. The number of teeth on the first gear 911 is less than the number of teeth on the second gear 912. The meshing of the first gear 911 and the second gear 912 enables the transmission of power output from the drive member 1 to the rotating shaft 6, thereby driving the moving structure 3 to rotate and achieving the damping of the shock absorber 100.

[0134] Furthermore, since the number of teeth of the first gear 911 is less than the number of teeth of the second gear 912, the first gear 911 is mounted on the output shaft of the drive member 1, and the second gear 912 is mounted on the rotating shaft 6. In other words, the first gear 911 and the second gear 912 form a speed reduction transmission mechanism 91. The first gear 911 and the second gear 912 can reduce speed and increase torque for the drive member 1. Only a small output torque of the drive member 1 is needed to drive the rotating member 2 to rotate. On the one hand, this is beneficial to save the cost of the drive member 1, and on the other hand, it is also beneficial to save the space occupied by the drive member 1 in the shock absorber 100.

[0135] This disclosure does not limit the specific installation position of the gear transmission mechanism 93 within the shock absorber 100. As one embodiment of this disclosure, for example... Figure 8As shown, the shock absorber 100 also includes a housing 30, a drive component 1, a gear transmission mechanism 93, a rotating shaft 6, and a rotating component 2, all located within the housing 30. A portion of the movable structure 3 is also located within the housing 30, and at least a portion of the movable shaft 33 extends through the housing 30. The housing 30 serves two purposes: firstly, it houses the gear transmission mechanism; secondly, it protects the drive component 1, the gear transmission mechanism 93, and the rotating component 2, effectively preventing the shock absorber 100 from malfunctioning due to dust or other impurities during use.

[0136] To facilitate the installation of the shock absorber 100 on the equipment to be damped, optionally, such as Figure 6 and Figure 7 As shown, a shock absorber mounting base 7 is provided on the top of the housing 30. In other words, the shock absorber 100 is mounted on the device to be damped by means of the shock absorber mounting base 7 provided on the housing 30, thereby damping the device to be damped.

[0137] In an embodiment where the axis of the output shaft of the drive member 1 intersects the axis of the rotating shaft 6, in order to transmit the power of the drive member 1 to the rotating shaft 6, optionally, as follows: Figure 6 and Figure 7 As shown, the transmission mechanism 9 includes a reversing transmission mechanism 92. The reversing transmission mechanism 92 can change the transmission direction of the power of the driving member 1, thereby enabling the driving member 1 to drive the rotating shaft 6 to rotate.

[0138] Optionally, such as Figure 6 and Figure 7 As shown, the output shaft of the drive component 1 is connected to the rotating shaft 6 via a reversing transmission mechanism 92. In this way, the reversing transmission mechanism 92 can transmit the power output from the output shaft of the drive component 1 to the rotating shaft 6, thereby driving the moving structure 3 to move and realizing the vibration reduction of the shock absorber 100.

[0139] This disclosure does not limit the specific composition of the reversing transmission mechanism 92. As one embodiment of this disclosure, the reversing transmission mechanism 92 includes a first reversing transmission member 921 and a second reversing transmission member 922. The axis of the first reversing transmission member 921 intersects the axis of the second reversing transmission member 922. The first reversing transmission member 921 is drive-connected to the output shaft of the drive member 1, and the second reversing transmission member 922 is drive-connected to the rotating shaft 6. Through the first reversing transmission member 921 and the second reversing transmission member 922, the direction of the power transmitted by the output shaft of the drive member 1 can be changed, thereby enabling the output shaft of the drive member 1 to drive the rotating shaft 6 to rotate.

[0140] This disclosure does not limit the specific types of the first reversing drive member 921 and the second reversing drive member 922. As one embodiment of this disclosure, for example... Figure 7As shown, the first reversing transmission component 921 is a first bevel gear 9211, and the second reversing transmission component 922 is a second bevel gear 9221. The first bevel gear 9211 and the second bevel gear 9221 mesh with each other. The meshing first bevel gear 9211 and the second bevel gear 9221 can change the direction of the power transmitted by the output shaft of the drive component 1, so that the output shaft of the drive component 1 can drive the rotating shaft 6 to rotate, thereby driving the moving structure 3 to move, and realizing the vibration reduction of the shock absorber 100.

[0141] In another embodiment of this disclosure, one of the first reversing transmission member 921 and the second reversing transmission member 922 is a worm gear, and the other of the first reversing transmission member 921 and the second reversing transmission member 922 is a worm wheel. The worm gear can also change the direction of the power transmitted by the output shaft of the drive member 1, thereby enabling the output shaft of the drive member 1 to drive the rotating shaft 6 to rotate.

[0142] In an embodiment where the shock absorber 100 includes a reversing transmission mechanism 92, the output shaft of the drive member 1 can be directly connected to the rotating shaft 6 via the reversing transmission mechanism 92, or the output shaft of the drive member 1 can be indirectly connected to the rotating shaft 6 via the reversing transmission mechanism 92. This disclosure does not limit this aspect. As one embodiment of this disclosure, such as... Figure 7 As shown, the first reversing transmission component 921 is mounted on the output shaft of the drive component 1, and the second reversing transmission component 922 is mounted on the rotating shaft 6. In other words, the output shaft of the drive component 1 can be directly connected to the rotating shaft 6 through the reversing transmission mechanism 92. The reversing transmission mechanism 92 can both change the direction of the power transmitted by the output shaft of the drive component 1 and transmit the power output by the output shaft of the drive component 1.

[0143] In another embodiment of this disclosure, the shock absorber 100 further includes an intermediate drive shaft 20, which is connected to the rotating shaft 6. A first reversing drive component 921 is mounted on the output shaft of the drive component 1, and a second reversing drive component 922 is mounted on the intermediate drive shaft 20. In other words, the output shaft of the drive component 1 is indirectly connected to the rotating shaft 6 through the reversing drive mechanism 92 and the intermediate drive shaft 20.

[0144] For embodiments with an intermediate drive shaft 20, such as Figure 7As shown, the shock absorber 100 can also be equipped with a speed reduction transmission mechanism 91. The second reversing transmission member 922 is connected to the intermediate transmission shaft 20, and the intermediate transmission shaft 20 is connected to the rotating shaft 6 through the speed reduction transmission mechanism 91. In other words, the power output from the output shaft of the drive member 1 is first transmitted to the rotating shaft 6 through the reversing transmission mechanism 92 and then through the speed reduction transmission mechanism 91. On the one hand, the reversing transmission mechanism 92 can change the direction of the power output by the drive member 1. On the other hand, the speed reduction transmission mechanism 91 can also increase the torque output by the drive member 1, so that the rotating shaft 6 can obtain a larger torque to drive its rotation.

[0145] Optionally, such as Figure 7 As shown, the axis of the intermediate drive shaft 20 is parallel to the axis of the rotating shaft 6. The reduction transmission mechanism 91 includes a first gear 911 and a second gear 912 that mesh with each other. The first gear 911 is mounted on the intermediate drive shaft 20, and the second gear 912 is mounted on the rotating shaft 6. The number of teeth on the first gear 911 is less than the number of teeth on the second gear 912. Because the number of teeth on the first gear 911 is less than the number of teeth on the second gear 912, the output speed of the reduction transmission mechanism 91 is less than the input speed of the reduction transmission mechanism 91, and the output torque of the reduction transmission mechanism 91 is greater than the input torque of the reduction transmission mechanism 91. The reduction transmission mechanism 91 can reduce speed and increase torque for the drive component 1. Only a drive component 1 with a smaller output torque is needed to drive the rotating component 2 to rotate. This is beneficial for saving the cost of the drive component 1 and also for saving the space occupied by the drive component 1 in the shock absorber 100.

[0146] To improve the damping capacity and damping range of the shock absorber 100, optionally, such as Figures 9 to 11 As shown, there can be multiple rotating members 2 (for example, multiple rotating members 2 may include the first transmission member 40 and the second transmission member 40 mentioned below), and the multiple rotating members 2 have different shapes and / or sizes. The shock absorber 100 also includes a transmission engagement mechanism 8, which is configured to selectively drive any rotating member 2 to the drive member 1.

[0147] Because the multiple rotating parts 2 have different shapes and / or sizes, and the transmission engagement mechanism 8 is configured to selectively connect any rotating part 2 to the driving part 1, in other words, the moving structure 3 moves within different ranges under the action of the multiple rotating parts 2. That is, the multiple rotating parts 2 can each drive the moving structure 3 to move different distances in the first direction. Thus, on the one hand, by switching the multiple rotating parts 2 so that different rotating parts 2 drive the moving structure 3, the moving structure 3 can have different displacements in the first direction, thereby enabling the shock absorber 100 to have different damping capabilities and damping ranges.

[0148] On the other hand, in the implementation where the rotating member 2 is driven by the driving member 1, multiple rotating members 2 can also simplify the control precision requirements of the driving member 1. When the vibration is small, by switching different rotating members 2, the moving structure 3 can have a small range of movement in the first direction even without high-precision control of the driving member 1. In other words, the shock absorber 100 can be adapted to different shock absorption needs without improving the control precision of the driving member 1, and the control requirements of the driving member 1 are low.

[0149] like Figures 9 to 14 As shown, this disclosure also provides a shock absorber 100, which includes a first transmission member 40, a second transmission member 50, and a moving structure 3. The moving structure 3 is adapted to be connected to the component to be damped. Both the first transmission member 40 and the second transmission member 50 are adapted to be connected to the driving member 1. The moving structure 3 can be selectively connected to the driving member 1 via the first transmission member 40 or the second transmission member 50, so that the moving structure 3 can move in a first direction under the action of the first transmission member 40 or the second transmission member 50. The range of movement of the moving structure 3 under the action of the first transmission member 40 is different from the range of movement of the moving structure 3 under the action of the second transmission member 50.

[0150] In the shock absorber 100 described above, since the movable structure 3 can be connected to the component to be damped, the first transmission member 40 and the second transmission member 50 are adapted to be connected to the driving member 1. Both the first transmission member 40 and the second transmission member 50 can drive the movable structure 3 to move along the first direction. Thus, by driving the first transmission member 40 or driving the second transmission member 50 to move, the movable structure 3 can be driven to move in the first direction in the opposite direction to the vibration direction. In other words, by driving the first transmission member 40 or the second transmission member 50, the direction of movement of the movable structure 3 in the shock absorber 100 in the first direction can be made opposite to the direction of vibration. In this way, the movement of the movable structure 3 of the shock absorber 100 reduces or cancels the vibration of the component to be damped, thereby achieving damping.

[0151] Furthermore, since the range of movement of the movable structure 3 under the action of the first transmission member 40 is different from the range of movement of the movable structure 3 under the action of the second transmission member 50, in other words, the first transmission member 40 and the second transmission member 50 can drive the movable structure 3 to move different distances in the first direction. Thus, on the one hand, by switching the first transmission member 40 and the second transmission member 50, so that different transmission members drive the movable structure 3 to move, the movable structure 3 can have different displacement ranges in the first direction, thereby enabling the shock absorber 100 to have different damping capabilities and damping ranges. For example, one of the first transmission member 40 and the second transmission member 50 can adapt to large-amplitude low-frequency vibrations, while the other of the first transmission member 40 and the second transmission member 50 can adapt to small-amplitude high-frequency vibrations. On the other hand, it can also simplify the control precision requirements of the drive component 1. When the vibration is small, the drive component 40 and the second drive component 50 that can drive the moving structure 3 to move within a small range of movement can be used to drive the moving structure 3 to move. In this way, even without high-precision control of the drive component 1, the moving structure 3 can have a small range of movement in the first direction. In other words, without improving the control precision of the drive component 1, the shock absorber 100 can be adapted to different shock absorption requirements, and the control requirements of the drive component 1 are reduced.

[0152] To make the range of movement of the movable structure 3 under the action of the first transmission member 40 different from the range of movement of the movable structure 3 under the action of the second transmission member 50, optionally, as follows: Figures 9 to 11 As shown, the size and / or shape of the first transmission member 40 is different from that of the second transmission member 50. Because the size and / or shape of the first transmission member 40 is different from that of the second transmission member 50, the moving structure 3 moves a different distance in the first direction under the action of the first transmission member 40 or the second transmission member 50, thus making the range of movement of the moving structure 3 under the action of the first transmission member 40 different from the range of movement of the moving structure 3 under the action of the second transmission member 50.

[0153] For example, if both the first transmission member 40 and the second transmission member 50 drive the moving structure 3 to move by means of movement, the length of the first transmission member 40 in the first direction may be different from the length of the second transmission member 50 in the first direction. For example, if both the first transmission member 40 and the second transmission member 50 drive the moving structure 3 to move by means of rotation, the diameters of the first transmission member 40 and the second transmission member 50 may be different, or the outer contour shapes of the first transmission member 40 and the second transmission member 50 may be different.

[0154] This disclosure does not limit how the first transmission member 40 and the second transmission member 50 drive the moving structure 3 to move along the first direction. The first transmission member 40 and / or the second transmission member 50 may be rotatable and may drive the moving structure 3 to move during rotation.

[0155] The first transmission member 40 and / or the second transmission member 50 can also be movable, thereby driving the movable structure 3 to move.

[0156] In one embodiment of this disclosure, the first transmission member 40 is rotatable and drives the movable structure 3 to move in a first direction, and the second transmission member 50 is also rotatable and drives the movable structure 3 to move in the first direction. The maximum distance from the rotation center of the first transmission member 40 to its outline edge is different from the maximum distance from the rotation center of the second transmission member 50 to its outline edge, and / or, the minimum distance from the rotation center of the first transmission member 40 to its outline edge is different from the minimum distance from the rotation center of the second transmission member 50 to its outline edge. Thus, the first transmission member 40 and the second transmission member 50 can drive the movable structure 3 to move different distances in the first direction.

[0157] In the above embodiments, the first transmission member 40 and the second transmission member 50 may have the same shape and / or size, but the positions of their rotation centers on the first transmission member 40 and the second transmission member 50 may differ. For example, the first transmission member 40 may be a first disk, and the second transmission member 50 may be a second disk. The first and second disks may have the same diameter. The rotation center of the first disk may be offset from its center, and the center of the second disk may be offset from its center. The distances by which the rotation center of the first disk deviates from its center are different from the distances by which the rotation center of the second disk deviates from its center.

[0158] To facilitate control of the first transmission member 40 or the second transmission member 50 to drive the moving structure 3 to move along the first direction, optionally, both the first transmission member 40 and the second transmission member 50 can drive the moving structure 3 to reciprocate in the first direction when rotating in one direction. In other words, the first transmission member 40 and the second transmission member 50 do not need to repeatedly change their rotation direction; they only need to rotate in one direction to drive the moving structure 3 to move, thereby achieving shock absorption. The control requirements for the shock absorber 100 are relatively low.

[0159] To facilitate switching the damping capacity and damping range of the shock absorber 100 during use, as one embodiment of this disclosure, such as Figures 9 to 11As shown, the shock absorber 100 also includes a transmission engagement mechanism 8, which is adapted to be connected to the drive member 1. The transmission engagement mechanism 8 can selectively connect to the first transmission member 40 or the second transmission member 50 to transmit the power of the drive member 1 to the first transmission member 40 or the second transmission member 50. In this way, through the transmission engagement mechanism 8, the moving structure 3 can be driven by different transmission members, thereby enabling the shock absorber 100 to have different damping capabilities and damping ranges, and the switching between different damping capabilities and damping ranges of the shock absorber 100 is relatively convenient.

[0160] To facilitate switching of the transmission engagement mechanism 8 between the first transmission member 40 and the second transmission member 50, optionally, as follows: Figures 9 to 11 As shown, the shock absorber 100 also includes a rotating shaft 6, which is adapted to be connected to the driving member 1. The first driving member 40 and the second driving member 50 are both loosely fitted onto the rotating shaft 6. The transmission engagement mechanism 8 can selectively connect the first driving member 40 or the second driving member 50 to the rotating shaft 6, so that the rotating shaft 6 can drive the first driving member 40 or the second driving member 50 to rotate. Thus, by connecting the transmission engagement mechanism 8 to the first driving member 40, or to the second driving member 50, the rotating shaft 6 can selectively drive the moving structure 3 to move via the first driving member 40 or the second driving member 50, giving the shock absorber 100 different damping capabilities and damping ranges.

[0161] Optionally, such as Figures 9 to 11 As shown, the transmission engagement mechanism 8 includes an engagement member 81 and an actuator. The engagement member 81 is driveably connected to the rotating shaft 6. A first engagement portion 401 is provided on the first transmission member 40, and a second engagement portion 501 is provided on the second transmission member 50. The actuator is used to drive the engagement member 81 to move, so that the engagement member 81 is driveably engaged with the first engagement portion 401 or the second engagement portion 501. In other words, by adjusting the position of the engagement member 81 by the actuator, the engagement member 81 can be driveably engaged with the first transmission member 40, or the engagement member 81 can be engaged with the second transmission member 50, so that the moving structure 3 can be driven by different transmission members (i.e., the first transmission member 40 or through the second transmission member 50), thereby giving the shock absorber 100 different damping capabilities and damping ranges.

[0162] For embodiments of the transmission engagement mechanism 8 including the engaging member 81 and the actuating member, this disclosure does not limit the specific types of the engaging member 81 and the actuating member. As one embodiment of this disclosure, such as... Figures 9 to 11As shown, the aforementioned coupling member 81 is a gear 82 mounted on the rotating shaft 6. A first through hole 402 is formed on the first transmission member 40, and a second through hole 502 is formed on the second transmission member 50. Both the first through hole 402 and the second through hole 502 allow the rotating shaft 6 to pass through. The first engagement portion 401 is a first tooth 403 mounted on the wall of the first through hole 402, and the second engagement portion 501 is a second tooth 503 mounted on the wall of the second through hole. Both the first tooth 403 and the second tooth 503 can mesh with the gear. In other words, the coupling member 81 and the first transmission member 40, as well as the coupling member 81 and the second transmission member 50, are all driven by gear meshing. The gear-driven coupling member 81 and the first transmission member 40, as well as the coupling member 81 and the second transmission member 50, have a compact structure and high transmission efficiency.

[0163] In a second embodiment of this disclosure, the aforementioned coupling member 81 can also be a friction disc disposed on the rotating shaft 6, the first coupling portion 401 is a first friction portion disposed on the first transmission member 40, and the second coupling portion 501 is a second friction portion disposed on the second transmission member 50. Both the first and second friction portions can make transmission contact with the friction disc. In other words, the friction disc can form frictional contact with either the first or second friction portion, and torque can also be transmitted between the friction disc in frictional contact and the first transmission member 40 or between the friction disc in frictional contact and the second transmission member 50. This allows the moving structure 3 to be driven by different transmission members (i.e., the first transmission member 40 or the second transmission member 50), thereby enabling the shock absorber 100 to have different damping capabilities and damping ranges.

[0164] This disclosure does not limit the specific connection relationship between the coupling member 81 and the rotating shaft 6. As a first embodiment of this disclosure, the coupling member 81 is circumferentially locked and axially movable, sleeved on the rotating shaft 6. The actuator is connected to the coupling member 81 and is used to drive the coupling member 81 to move on the rotating shaft 6. In other words, the coupling member 81 can move on the rotating shaft 6 under the action of the actuator, thereby connecting with the first transmission member 40 or the second transmission member 50 to transmit the power of the driving member 1 to the first transmission member 40 or the second transmission member 50.

[0165] In a second embodiment of this disclosure, the coupling member 81 is fixedly mounted on the rotating shaft 6, and the actuator is connected to the rotating shaft 6 and used to drive the rotating shaft 6 to move, thereby causing the coupling member 81 to move. In other words, the coupling member 81 and the rotating shaft 6 are fixedly connected, and the actuator can drive the coupling member 81 and the rotating shaft 6 to move together, so that the coupling member 81 is respectively connected to the first transmission member 40 or the second transmission member 50, transmitting the power of the driving member 1 to the first transmission member 40 or the second transmission member 50.

[0166] In a third embodiment of this disclosure, the coupling member 81 is fixedly mounted on the rotating shaft 6. The actuator is connected to the driving member 1 and is used to drive the driving member 1 to move, thereby causing the driving member, the rotating shaft 6, and the coupling member 81 to move together. In other words, the coupling member 81, the rotating shaft 6, and the driving member 1 are all fixedly connected. The actuator can drive the coupling member 81, the rotating shaft 6, and the driving member 1 to move, thereby enabling the coupling member 81 to be connected to the first transmission member 40 or the second transmission member 50 respectively, transmitting the power of the driving member 1 to the first transmission member 40 or the second transmission member 50.

[0167] Optionally, the actuator mentioned above can be a linear motor.

[0168] This disclosure does not limit the specific implementation of how the first transmission member 40 or the second transmission member 50 drives the movable structure 3 to move along the first direction. As one embodiment of this disclosure, the movable structure 3 has a contact portion 34, which is adapted to contact the first transmission member 40 and the second transmission member 50, so that the first transmission member 40 and the second transmission member 50 can push the movable structure 3 through the contact portion 34 during rotation. In other words, the contour edges of both the first transmission member 40 and the second transmission member 50 can contact the contact portion 34 of the movable structure 3. Thus, during the transmission process of the first transmission member 40 and the second transmission member 50, the contact portion 34 of the movable structure 3 can move under the pushing action of the contour edge of the rotating member 2, thereby realizing the movement of the movable structure 3 along the first direction.

[0169] This disclosure does not limit the specific structure of the movable structure 3, as long as the movable structure 3 can cooperate with the first transmission member 40 or the second transmission member 50, and can move along the first direction under the action of the first transmission member 40 or the second transmission member 50, it is acceptable. As one embodiment of this disclosure, such as... Figures 11 to 14 As shown, the movable structure 3 includes a movable frame 31, which has a contact portion 34. The contact portion 34 includes an upper contact member 311 and a lower contact member 312. The upper contact member 311 and the lower contact member 312 are arranged opposite to each other along a first direction. The first transmission member 40 and the second transmission member 50 are both located between the upper contact member 311 and the lower contact member 312, so that the first transmission member 40 and the second transmission member 50 can push the upper contact member 311 or the lower contact member 312 during rotation.

[0170] Since the contact portion 34 provided on the movable frame 31 includes an upper contact member 311 and a lower contact member 312 disposed opposite to each other along the first direction, and the first transmission member 40 or the second transmission member 50 can push the upper contact member 311 or the lower contact member 312 during rotation, in other words, during the rotation of the first transmission member 40 or the second transmission member 50, the contour edge of the first transmission member 40 or the second transmission member 50 can contact at least one of the upper contact member 311 and the lower contact member 312. Thus, even if the first transmission member 40 or the second transmission member 50 always rotates in one direction, the upper contact member 311 and / or the lower contact member 312 can still contact the contour edge of the first transmission member 40 or the second transmission member 50, thereby realizing the reciprocating movement of the movable structure 3 along the first direction.

[0171] Optionally, such as Figures 11 to 14 As shown, the upper contact 311 includes a first upper contact portion 3111 and a second upper contact portion 3112, and the lower contact 312 includes a first lower contact portion 3121 and a second lower contact portion 3122. The first transmission member 40 is located between the first upper contact portion 3111 and the first lower contact portion 3121, and the first transmission member 40 can push the first upper contact portion 3111 or the first lower contact portion 3121 during rotation. The second transmission member 50 is located between the second upper contact portion 3112 and the second lower contact portion 3122, and the second transmission member 50 can push the second upper contact portion 3112 and the second lower contact portion 3122 during rotation. In a first direction, the distance from the first upper contact portion 3111 to the first lower contact portion 3121 is different from the distance from the second upper contact portion 3112 to the second lower contact portion 3122.

[0172] Since the distance between the first upper contact portion 3111 and the first lower contact portion 3121 is different from the distance between the second upper contact portion 3112 and the second lower contact portion 3122 in the first direction, it can be understood that the first upper contact portion 3111 and the first lower contact portion 3121 are adapted to the first transmission member 40, and the second upper contact portion 3112 and the second lower contact portion 3122 are adapted to the second transmission member 50. The first upper contact portion 3111 and the first lower contact portion 3121 can cooperate with the first transmission member 40, and the second upper contact portion 3112 and the second lower contact portion 3122 can cooperate with the second transmission member 50, so that the moving structure 3 can move along the first direction under the action of the first transmission member 40 or the second transmission member 50.

[0173] This disclosure does not limit the specific structure of the first upper contact portion 3111, the first lower contact portion 3121, the second upper contact portion 3112, and the second lower contact portion 3122. As one embodiment of this disclosure, the shock absorber 100 is as follows: Figures 11 to 14As shown, the upper contact 311 includes a first body 3113 and a first protrusion 3114 disposed on the first body 3113. The first protrusion 3114 protrudes from the first body 3113. The lower contact 312 includes a second body 3123 and a second protrusion 3124 disposed on the second body 3123. The second protrusion 3124 protrudes from the second body 3123. The first protrusion 3114 and the second protrusion 3124 are disposed opposite to each other along a first direction and protrude towards each other. The first body 3113 is the first upper contact portion 3111, the first protrusion 3114 is the second upper contact portion 3112, the second body 3123 is the first lower contact portion 3121, and the second protrusion 3124 is the second lower contact portion 3122.

[0174] It should be noted that the first protrusion 3114 and the second protrusion 3124 protruding towards each other means that the first protrusion 3114 protrudes towards the direction closer to the second protrusion 3124, and the second protrusion 3124 protrudes towards the direction closer to the first protrusion 3114.

[0175] The first transmission member 40 can push the first body 3113 or the second body 3123 during rotation, and the second transmission member 50 can push the first protrusion 3114 or the second protrusion 3124 during rotation. This pushes the moving frame 31 to move along the first direction.

[0176] To improve the versatility of the movable box 31, optionally, such as Figures 11 to 14 As shown, the first protrusion 3114 is detachably mounted on the first body 3113, and the second protrusion 3124 is detachably mounted on the second body 3123. In other words, both the first protrusion 3114 and the second protrusion 3124 are detachably mounted on the movable frame 31. Thus, if the first protrusion 3114 and / or the second protrusion 3124 are damaged, the operator can directly replace them with new ones without replacing the entire movable frame 31, resulting in lower operating costs for the movable frame 31. Furthermore, the operator can replace the first transmission component 40 with different sizes and / or shapes, and replace the first protrusion 3114 and the second protrusion 3124 with different sizes, thereby giving the shock absorber 100 different damping capabilities and improving its versatility.

[0177] To prevent the first transmission member 40, the first upper contact portion 3111, and the first lower contact portion 3121 from colliding with each other during rotation, and to prevent the second transmission member 50, the second upper contact portion 3112, and the second lower contact portion 3122 from colliding with each other during rotation, optionally, the first transmission member 40 is configured such that the outline edge (i.e., the outer peripheral surface) of the first transmission member 40 remains in contact with the first body 3113 and the second body 3123 during rotation, and the second transmission member 50 is configured such that the outline edge of the second transmission member 50 remains in contact with the first protrusion 3114 and the second protrusion 3124 during rotation.

[0178] In other words, during the rotation of the first transmission member 40, the first transmission member 40 can always be in contact with the first upper contact portion 3111 and the first lower contact portion 3121, and the second transmission member 50 can always be in contact with the second upper contact portion 3112 and the second lower contact portion 3122. Thus, during rotation, the first transmission member 40, the first upper contact portion 3111, and the first lower contact portion 3121, which are always in contact, will not collide with each other, nor will the second transmission member 50, the second upper contact portion 3112, and the second lower contact portion 3122, which are always in contact, collide with each other. The shock absorber 100 itself will not vibrate. On the one hand, this improves the shock absorption effect of the shock absorber 100. On the other hand, it also avoids the collision between the first transmission member 40, the first upper contact portion 3111, and the first lower contact portion 3121, and / or between the second transmission member 50, the second upper contact portion 3112, and the second lower contact portion 3122, which could lead to the easy damage of one or more of the first transmission member 40, the first body 3113, the second body 3123, the second transmission member 50, the first protrusion 3114, and the second protrusion 3124.

[0179] Optionally, in the first direction, there is a first distance between the first upper contact portion 3111 and the first lower contact portion 3121, and a second distance between the contact point between the first transmission member 40 and the first upper contact portion 3111 and the contact point between the first transmission member 40 and the first lower contact portion 3121, wherein the first distance is equal to the second distance.

[0180] In other words, the distance between the two contact points of the first transmission member 40 that contact the first upper contact portion 3111 and the first lower contact portion 3121 is equal to the distance between the first upper contact portion 3111 and the first lower contact portion 3121. In this way, by reasonably designing the shape of the first transmission member 40, the contour edge of the first transmission member 40 can always maintain contact with the first upper contact portion 3111 and the first lower contact portion 3121 during rotation. The first transmission member 40, the first upper contact portion 3111, and the first lower contact portion 3121 that are always in contact will not collide, and the shock absorber 100 itself will not vibrate. On the one hand, this improves the shock absorption effect of the shock absorber 100, and on the other hand, it also avoids the situation where the first transmission member 40, the first upper contact portion 3111, and the first lower contact portion 3121 collide with each other, which would easily lead to the damage of one or more of the first transmission member 40, the first upper contact portion 3111, and the first lower contact portion 3121.

[0181] Optionally, in the first direction, there is a third distance between the second upper contact portion 3112 and the second lower contact portion 3122, and a fourth distance between the contact point of the second transmission member 50 and the second upper contact portion 3112 and the contact point of the first transmission member 40 and the first lower contact portion 3121, wherein the third distance is equal to the fourth distance.

[0182] In other words, the distance between the two contact points of the second transmission member 50 that contact the second upper contact portion 3112 and the second lower contact portion 3122 is equal to the distance between the second upper contact portion 3112 and the second lower contact portion 3122. In this way, by reasonably designing the shape of the second transmission member 50, the outline edge of the second transmission member 50 can always maintain contact with the second upper contact portion 3112 and the second lower contact portion 3122 during rotation. The second transmission member 50, the second upper contact portion 3112, and the second lower contact portion 3122, which are always in contact, will not collide, and the shock absorber 100 itself will not vibrate. On the one hand, this improves the shock absorption effect of the shock absorber 100, and on the other hand, it also avoids the situation where the second transmission member 50, the second upper contact portion 3112, and the second lower contact portion 3122 collide with each other, which could easily lead to damage to one or more of the second transmission member 50, the second upper contact portion 3112, and the second lower contact portion 3122.

[0183] Here, this disclosure does not limit the specific type of the first transmission member 40 and the second transmission member 50. As one embodiment of this disclosure, the first transmission member 40 and / or the second transmission member 50 is a cam 21, and the cross-section of the cam 21 is a Reichstag polygon.

[0184] Since the Leno polygon has the same width in any direction, by reasonably setting the distance between the first body 3113 and the second body 3123 that are arranged opposite to each other along the first direction, and the distance between the first protrusion 3114 and the second protrusion 3124 that are arranged opposite to each other along the first direction, the first transmission member 40 of the cam 21 with the cross-section formed as a Leno polygon can always keep in contact with the first body 3113 and the second body 3123, and / or the second transmission member 50 of the cam 21 with the cross-section formed as a Leno polygon can always keep in contact with the first protrusion 3114 and the second protrusion 3124.

[0185] This disclosure does not limit the number of sides of the Leno polygon, and optionally, the cross-section of the cam 21 is formed as a Leno triangle.

[0186] To facilitate the connection of the shock absorber 100 to the component to be damped, as one embodiment of this disclosure, such as Figure 14 As shown, the movable structure 3 also includes a movable shaft 33. The first end of the movable shaft 33 is connected to the movable frame 31, and the second end of the movable shaft 33 is used to connect to the component to be damped. In other words, the movable structure 3 of the shock absorber 100 is connected to the component to be damped via the movable shaft 33, and the shock absorber 100 can dampen the component.

[0187] To further improve the damping effect of the shock absorber 100, optionally, such as Figure 11 As shown, the shock absorber 100 also includes an elastic element 4, which is sleeved on the movable shaft 33.

[0188] Since the elastic element 4 is sleeved on the moving shaft 33, the elastic element 4 can absorb the impact of vibration and improve the shock absorption effect of the shock absorber 100.

[0189] For example, when the shock absorber 100 is used for vehicle damping, the elastic element 4 can absorb the impact of the road surface, thereby improving the damping effect of the shock absorber 100.

[0190] It should be noted that this disclosure does not limit the specific type of the elastic element 4. As one embodiment of this disclosure, the elastic element 4 is configured as a spring. As other embodiments, the elastic element 4 can also be an elastic sleeve, etc.

[0191] Optionally, the shock absorber 100 further includes a housing 30, with at least a portion of the movable structure 3 disposed within the housing 30 and guided by the inner wall of the housing 30. The inner wall of the housing 30 can guide the movement of at least a portion of the movable structure 3, preventing the movable structure 3 from rotating with the rotating member 2 and causing the shock absorber 100 to fail to dampen vibrations.

[0192] This disclosure does not limit the specific type of the first transmission member 40. As one embodiment of this disclosure, the first transmission member 40 can be constructed as a first cam 404. As another embodiment of this disclosure, the first transmission member 40 can be constructed as a first disk.

[0193] In the embodiment where the first transmission member 40 is configured as a first disk, to ensure that the distance between the outline edge of the first transmission member 40 and the rotation center of the first transmission member 40 continuously changes in the first direction during rotation, optionally, the rotation center of the first disk is eccentrically positioned relative to the center of the first disk. In other words, the rotation center of the first disk does not coincide with the center of the first disk. Thus, during the rotation of the first disk, the distance between the rotation center of the first disk and the outline edge of the first disk continuously changes in the first direction, thereby driving the moving structure 3 to move in the first direction.

[0194] In the embodiment where the first transmission member 40 is configured as a first cam 404, to improve the damping range of the shock absorber 100, optionally, the rotation center of the first cam 404 is eccentrically set relative to the center of the base circle of the first cam 404 and / or the geometric center of the first cam 404. Because the rotation center of the first cam 404 is eccentrically set relative to the base circle of the first cam 404 and / or the geometric center of the first cam 404, during the rotation of the first cam 404, the difference between the maximum and minimum distances between the rotation center of the first cam 404 and the contour edge of the first cam 404 along the first direction increases. In other words, the eccentrically set first cam 404 has a larger push stroke and a smaller return stroke. Thus, during the rotation of the first cam 404, the distance that the first cam 404 can drive the moving structure 3 to move along the first direction increases, and the shock absorber 100 can have a larger damping range.

[0195] This disclosure does not limit the specific type of the second transmission member 50. As one embodiment of this disclosure, the second transmission member 50 can be configured as a second cam 504. As another embodiment of this disclosure, the second transmission member 50 can be configured as a second disk.

[0196] In the embodiment where the second transmission member 50 is configured as a second disk, to ensure that the distance between the outline edge of the second transmission member 50 and the rotation center of the second transmission member 50 continuously changes in the second direction during rotation, optionally, the rotation center of the second disk is eccentrically positioned relative to the center of the second disk. In other words, the rotation center of the second disk does not coincide with the center of the second disk. Thus, during the rotation of the second disk, the distance between the rotation center of the second disk and the outline edge of the second disk continuously changes in the second direction, thereby driving the moving structure 3 to move in the second direction.

[0197] In the embodiment where the second transmission member 50 is configured as a second cam 504, to improve the damping range of the shock absorber 100, the rotation center of the second cam 504 may optionally be eccentrically positioned relative to the center of the base circle and / or the geometric center of the second cam 504. Because the rotation center of the second cam 504 is eccentrically positioned relative to the base circle and / or the geometric center of the second cam 504, during the rotation of the second cam 504, the difference between the maximum and minimum distances between the rotation center of the second cam 504 and the contour edge of the second cam 504 along the second direction increases. In other words, the eccentrically positioned second cam 504 has a larger push stroke and a smaller return stroke. Thus, during the rotation of the second cam 504, the distance that the second cam 504 can drive the moving structure 3 to move along the second direction increases, and the shock absorber 100 can have a larger damping range.

[0198] In summary, compared with hydraulic shock absorbers in related technologies, the shock absorber 100 provided in this disclosure has a simpler structure, lower cost, smaller overall mass, and will not increase the overall weight of the vehicle.

[0199] Since the shock absorber 100 is a mechanical transmission structure, compared with the solenoid valve type shock absorber, the shock absorber 100 disclosed herein does not have an electromagnetic induction-related structure or electromagnetic induction process, so the shock absorber 100 disclosed herein has a faster response speed and higher reliability.

[0200] Furthermore, compared with magnetorheological dampers in the related art, the damper 100 disclosed herein does not have a damping medium. Therefore, the damper 100 disclosed herein does not have problems with durability, weather resistance, or adaptability. The damper 100 disclosed herein can be applied to a variety of complex environments.

[0201] This disclosure also provides a vehicle suspension, including the shock absorber 100 as described above.

[0202] The vehicle suspension has all the beneficial effects of the aforementioned shock absorber 100, which will not be elaborated here.

[0203] This disclosure also provides a vehicle including the vehicle suspension described above.

[0204] This vehicle possesses all the beneficial effects of the aforementioned vehicle suspension, which will not be elaborated upon here.

[0205] To achieve vehicle shock absorption, the vehicle may optionally include a body and wheels. The shock absorber 100 includes a shock absorber mounting base 7, which is mounted on the body. The moving structure 3 of the shock absorber 100 is connected to the wheels. In other words, the shock absorber 100 is mounted on the vehicle body via the shock absorber mounting base 7. Thus, during vehicle operation, if the vehicle is subjected to impacts from the road surface...
