[0041] The following refers to Figures 1 - 6 Describe the shock absorber assembly 100 according to an embodiment of the present utility model. By providing the shock absorber 3, the shock absorption function of the shock absorber assembly 100 can be realized. By providing the adjustment structure 4, the overall height of the shock absorber 3 can be adjusted, that is, the height of the vehicle body can be actively adjusted, realizing the height adjustment function of the shock absorber assembly 100, enabling the vehicle to adapt to different driving road conditions, effectively improving the passing performance and riding comfort of the vehicle, and being beneficial to improving user satisfaction.

[0042] As Figures 1 - 6 shown, a shock absorber assembly 100 according to an embodiment of the present utility model includes: a shock absorber 3 and an adjustment structure 4.

[0043] The shock absorber 3 includes a movable part 31 and a fixed part 32. The movable part 31 is movable relative to the fixed part 32; the adjustment structure 4 is connected to at least one of the movable part 31 and the fixed part 32 and is used to drive the movable part 31 to move relative to the fixed part 32 to adjust the overall height of the shock absorber 3.

In the shock absorber 3, a movable part 31 and a fixed part 32 are provided. The movable part 31 is movable relative to the fixed part 32 to buffer the vibration during vehicle jolts and play a role in shock absorption.

[0045] At the same time, the adjusting structure 4 is used to adjust the height of the vehicle body, further improving the ride comfort and driving stability of the vehicle. The adjusting structure 4 can be connected to one of the movable part 31 and the fixed part 32, or the adjusting structure 4 can be connected to both the movable part 31 and the fixed part 32 at the same time, so that the adjusting structure 4 can drive the movable part 31 to move relative to the fixed part 32 to adjust the height of the movable part 31, that is, to adjust the overall height of the shock absorber 3, and then the height of the vehicle body can be actively adjusted, so as to realize the height adjustment function of the shock absorber assembly 100, enabling the vehicle to adapt to different driving road conditions and improving the passing performance and ride comfort of the vehicle.

[0047] Thus, by arranging the shock absorber 3 in the shock absorber assembly 100, the movable part 31 in the shock absorber 3 can move relative to the fixed part 32 to buffer the vibration during vehicle jolts and improve the ride comfort and driving stability of the vehicle. At the same time, an adjusting structure 4 is also arranged in the shock absorber assembly 100. The adjusting structure 4 can be connected to one of the movable part 31 and the fixed part 32, or the adjusting structure 4 can be connected to both the movable part 31 and the fixed part 32 at the same time, so that the adjusting structure 4 can drive the movable part 31 to move relative to the fixed part 32 to adjust the overall height of the shock absorber 3, that is, the height of the vehicle body can be actively adjusted.

[0048] According to the shock absorber assembly 100 of the embodiment of the present invention, the shock absorber 3 can buffer the vibration during vehicle jolts to realize the shock absorption function of the shock absorber assembly 100.

[0049] In some embodiments, the adjusting structure 4 is connected to the movable part 31.

[0050] Specifically, the adjustment structure 4 can be used to drive the movable part 31 to move relative to the fixed part 32 to adjust the overall height of the shock absorber 3. The adjustment structure 4 can be connected to the movable part 31, so that the adjustment structure 4 can drive the movable part 31 to move relative to the fixed part 32 to adjust the height of the movable part 31, that is, the overall height of the shock absorber 3 can be adjusted. Furthermore, the height of the vehicle body can be actively adjusted to realize the height adjustment function of the shock absorber assembly 100, so that the vehicle can adapt to different driving road conditions and improve the passing performance and riding comfort of the vehicle.

[0051] In some embodiments, the adjustment structure 4 is connected to the fixed part 32.

[0052] Specifically, the adjustment structure 4 can be used to drive the movable part 31 to move relative to the fixed part 32 to adjust the overall height of the shock absorber 3. The adjustment structure 4 can be connected to the fixed part 32, so that the adjustment structure 4 can drive the movable part 31 to move relative to the fixed part 32 to adjust the height of the movable part 31, that is, the overall height of the shock absorber 3 can be adjusted. Furthermore, the height of the vehicle body can be actively adjusted to realize the height adjustment function of the shock absorber assembly 100, so that the vehicle can adapt to different driving road conditions and improve the passing performance and riding comfort of the vehicle.

[0053] In some embodiments, the adjustment structure 4 includes a stator assembly 41 and a rotor assembly 42. The stator assembly 41 is connected to the fixed part 32, and the rotor assembly 42 is connected to the movable part 31. The stator assembly 41 and the rotor assembly 42 interact with each other so that the rotor assembly 42 drives the movable part 31 to move relative to the fixed part 32.

[0054] Specifically, a stator assembly 41 and a rotor assembly 42 are provided in the adjustment structure 4. The rotor assembly 42 is movable relative to the stator assembly 41. The stator assembly 41 can be connected to the fixed part 32 so that the stator assembly 41 is relatively fixed to the fixed part 32. The rotor assembly 42 is connected to the movable part 31 so that the movable part 32 can move driven by the rotor assembly 42.

[0055] Furthermore, the stator assembly 41 and the rotor assembly 42 can interact with each other. When the stator assembly 41 is powered on, it can generate a driving force and drive the rotor assembly 42 to move. At this time, the rotor assembly 42 can drive the connected movable part 31 to move relative to the fixed part 32 to adjust the relative positional relationship between the movable part 31 and the fixed part 32, that is, the height of the movable part 31 can be actively adjusted, so that the height adjustment function of the shock absorber assembly 100 can be realized.

[0056] In some embodiments, the fixed part 32 includes a damping cylinder 321, the movable part 31 includes a damping rod 311 and a damping spring 312. One end of the damping rod 311 extends into the damping cylinder 321 and is movable relative to the damping cylinder 321. The damping spring 312 is sleeved outside the damping cylinder 321, and one end of the damping spring 312 is fixedly opposed to the other end of the damping rod 311. The mover assembly 42 is connected to the other end of the damping spring 312.

[0057] Specifically, as Figure 2 , Figure 3 and Figure 6 shown, the fixed part 32 includes a damping cylinder 321, the movable part 31 includes a damping rod 311, and by extending one end of the damping rod 311 into the damping cylinder 321, the damping rod 311 can be partially extended into the damping cylinder 321. Damping liquid 33 can be filled between the damping cylinder 321 and the damping rod 311, so that the shock absorber 3 in the present application can be applied to a hydraulic shock absorber. Among them, the damping rod 311 can be used for power transmission, the damping cylinder 321 can be used to accommodate the damping liquid 33, so that the damping rod 311 is movable relative to the damping cylinder 321. When the damping rod 311 moves relative to the damping cylinder 321, it can push the damping liquid 33 to flow. At this time, the damping liquid 33 can provide a damping force to the damping rod 311 to buffer the movement of the damping rod 311.

[0058] In addition, a damping spring 312 is further provided on the movable part 31. The damping spring 312 is used to absorb the vibration when the vehicle bumps, further improving the ride comfort and driving stability of the vehicle. The damping spring 312 is arranged outside the damping cylinder 321, and one end of the damping spring 312 is fixedly opposed to the other end of the damping rod 311, and the other end of the damping spring 312 is connected to the mover assembly 42, so that the installation of the damping spring 312 can be realized and the working reliability of the damping spring 312 can be improved.

[0059] In some embodiments, the shock absorber assembly 100 further includes a support seat 6. The support seat 6 is sleeved outside the damping cylinder 321 and is axially movable along the damping cylinder 321. The support seat 6 is connected between the mover assembly 42 and the other end of the damping spring 312.

[0060] Specifically, the support seat 6 is used to support the damping spring 312 to ensure the working reliability of the damping spring 312. By sleeving the support seat 6 outside the damping cylinder 321, the installation of the support seat 6 can be realized, and the support seat 6 can be radially limited to ensure the accuracy of the installation position of the support seat 6, and the support seat 6 is axially movable along the damping cylinder 321, that is, the support seat 6 can slide relative to the damping cylinder 321 along the axis of the damping cylinder 321.

[0061] Meanwhile, by connecting the support seat 6 between the mover assembly 42 and the other end of the damping spring 312, the support seat 6 can be connected to both the mover assembly 42 and the damping spring 312, enabling reliable installation of the support seat 6. Moreover, the damping spring 312, the support seat 6, and the mover assembly 42 can be arranged in sequence, allowing power to be transmitted between the damping spring 312 and the mover assembly 42 through the support seat 6. Additionally, the lower end of the damping spring 312 can be supported by the support seat 6, and the support seat 6 can support the damping spring 312 from below and axially limit it to ensure the reliability of the damping spring 312 during operation.

[0062] Furthermore, when power is transmitted from the mover assembly 42 to the damping spring 312 through the support seat 6, the height adjustment function of the shock absorber assembly 100 can be realized. The support seat 6 can be fixedly connected to the damping spring 312 and the mover assembly 42 to enhance the reliability of power transmission between the mover assembly 42 and the damping spring 312.

[0063] In some embodiments, a first bearing member 5 is provided between the inner peripheral wall of the support seat 6 and the outer peripheral wall of the damper cylinder 321.

[0064] Specifically, by arranging the first bearing member 5 between the inner peripheral wall of the support seat 6 and the outer peripheral wall of the damper cylinder 321, the support seat 6 can achieve sliding fit with the damper cylinder 321 through the first bearing member 5, enabling the support seat 6 to slide relative to the damper cylinder 321 to achieve power transmission with the damping spring 312, thereby realizing the height adjustment function of the shock absorber assembly 100.

[0065] Further, when the wheel is subjected to impacts and vibrations from the ground, it will drive the damper cylinder 321 and the stator assembly 41 to move. At this time, the damper rod 311 will move relative to the damper cylinder 321, and the damping fluid 33 will provide a damping force to the damper rod 311 to reduce the impacts and vibrations transmitted to the vehicle body and the occupants, that is, to realize the shock absorption function of the shock absorber assembly 100 and improve the driving stability and riding comfort of the vehicle. Meanwhile, the mover assembly 42 will move axially under the drive of the stator assembly 41 and push the support seat 6 to move. The support seat 6 slides relative to the damper cylinder 321 through the first bearing member 5 and transmits the power to the damping spring 312, causing the damping spring 312, the vehicle body, and the damper rod 311 to move simultaneously to realize the height adjustment function of the shock absorber assembly 100.

[0066] In some embodiments, the shock absorber assembly 100 further includes a connecting seat 7, and the mover assembly 42 and the support seat 6 are connected through the connecting seat 7.

[0067] Specifically, the mover assembly 42 is connected to the support base 6 through the connecting seat 7, so that the power between the mover assembly 42 and the support base 6 can be transmitted through the connecting seat 7. That is, the power on the mover assembly 42 can be transmitted from the connecting seat 7 to the support base 6, or the power on the support base 6 can be transmitted from the connecting seat 7 to the mover assembly 42. Among them, the mover assembly 42 and the support base 6 are connected in the vertical direction of the vehicle. The support base 6, the connecting seat 7, and the mover assembly 42 can be arranged in sequence in the vertical direction of the vehicle, so that the power can be transmitted between the mover assembly 42 and the support base 6 in the vertical direction of the vehicle.

[0068] Further, when the power of the mover assembly 42 is transmitted from the connecting seat 7 to the support base 6, it can be further transmitted to the shock-absorbing spring 312 to realize the height adjustment function of the shock absorber assembly 100.

[0069] And / or, the shock absorber assembly 100 further includes a mover inner sleeve 8. The mover inner sleeve 8 is located inside the mover assembly 42, and the mover inner sleeve 8 is slidably fitted with the damper cylinder 321 through a second bearing member 10.

[0070] Specifically, by arranging the mover inner sleeve 8 inside the mover assembly 42, the installation of the mover inner sleeve 8 can be realized, and the mover inner sleeve 8 is slidably fitted with the damper cylinder 321 through the second bearing member 10. That is, the mover inner sleeve 8 can slide relative to the damper cylinder 321 under the action of the second bearing member 10. Furthermore, the mover assembly 42 can slide relative to the damper cylinder 321 under the action of the second bearing member 10, and the mover assembly 42 can be protected by the mover inner sleeve 8 to avoid wear of the mover assembly 42 and extend the service life of the mover assembly 42. Among them, the second bearing member 10 can guide the movement of the mover assembly 42 to ensure the accuracy of its movement direction, and the second bearing member 10 can be a sliding bearing.

[0071] In addition, it should be noted that mover inner sleeves 8 are provided both inside and below the mover assembly 42 to protect the mover assembly 42. And in actual design, the second bearing member 10 and the first bearing member 5 can also be constructed as one body, which can reduce the number of bearing members and lower the setting cost.

[0072] In some embodiments, an installation bracket 9 is provided on the outer peripheral wall of the damper cylinder 321. The installation bracket 9 forms an installation groove 91, and the stator assembly 41 is installed in the installation groove 91 to be arranged in cooperation with the mover assembly 42.

[0073] Specifically, the installation bracket 9 is used to realize the installation of the stator assembly 41, so that the installation bracket 9 forms the installation groove 91. The installation groove 91 is used to accommodate the stator assembly 41. That is, the stator assembly 41 can be arranged in the installation groove 91 to realize the installation of the stator assembly 41, and the stator assembly 41 can be arranged in cooperation with the mover assembly 42.

[0074] For example, Figure 2 、 Figure 3 and Figure 6 As shown, the movable assembly 42 can be extended into the stator assembly 41, that is, the end of the movable assembly 42 away from the support seat 6 can be extended into the stator assembly 41 to cooperate with the stator assembly 41 so that the movable assembly 42 can move under the action of the stator assembly 41.

[0075] In some embodiments, the support seat 6 includes an axial portion 61 and a radial portion 62. The axial portion 61 is sleeved outside the damping cylinder 321 and slides with the damping cylinder 321. The radial portion 62 is connected to one end of the axial portion 61 and extends outward radially along the support seat 6. One end of the shock-absorbing spring 312 is sleeved outside the axial portion 61 and supported on the end face of the radial portion 62.

[0076] Specifically, the axial portion 61 is used to guide the movement of the shock absorber spring 312. The axial portion 61 is sleeved on the outer side of the damping cylinder 321 to realize the installation of the support seat 6, and the support seat 6 can be radially limited by the damping cylinder 321 to ensure the accuracy of the installation position of the support seat 6, and the axial portion 61 is slidably matched with the damping cylinder 321, so that the support seat 6 can slide relative to the damping cylinder 321, thereby driving the shock absorber spring 312 to slide relative to the damping cylinder 321 to realize the height adjustment function of the shock absorber assembly 100. At the same time, the radial portion 62 is used to support the shock absorber spring 312. The radial portion 62 is connected to the axial portion 61, so that the support seat 6 is a whole, which can improve the overall structural strength of the support seat 6, and the shock absorber spring 312 is supported on the upper end surface of the radial portion 62, so that the radial portion 62 can be used to support the shock absorber spring 312, and the shock absorber spring 312 can be axially limited from the bottom of the shock absorber spring 312.

[0077] In addition, by extending the radial portion 62 outward along the radial direction of the support seat 6, the radial portion 62 can have a certain length in the radial direction of the support seat 6, so as to improve the reliability of using the radial portion 62 to support and limit the vibration damping spring 312, and by sleeved one end of the vibration damping spring 312 outside the axial portion 61, the axial portion 61 can be used to radially limit the vibration damping spring 312, so as to effectively ensure the accuracy of the installation position of the vibration damping spring 312 and improve the reliability of the vibration damping spring 312.

[0078] It should be noted that if Figure 3 and Figure 6 As shown, a protrusion 63 is further provided below the radial portion 62. The protrusion 63 extends downward from the lower end surface of the radial portion 62 and presses against the outer side surface of the connecting seat 7 to radially limit the connecting seat 7 from the outer side surface of the connecting seat 7, thereby improving the accuracy of the installation position of the connecting seat 7 and the reliability of its operation.

[0080] Specifically, the stator assembly 41 is connected to the fixed part 32, and the fixed part 32 includes the damping cylinder 321. That is, the stator assembly 41 can be relatively fixed to the damping cylinder 321, and the stator assembly 41 can be fixedly connected to the damping cylinder 321, so that the stator assembly 41 can move driven by the damping cylinder 321, and there is no relative movement between the stator assembly 41 and the damping cylinder 321, ensuring the accuracy and reliability of adjusting the overall height of the shock absorber 3.

[0081] In some embodiments, the stator assembly 41 is sleeved outside the damping cylinder 321 and fixedly connected to the damping cylinder 321, and the rotor assembly 42 is sleeved outside the damping cylinder 321 and located between the damping cylinder 321 and the stator assembly 41.

[0082] Specifically, sleeving the stator assembly 41 outside the damping cylinder 321 can achieve the installation of the stator assembly 41, and the damping cylinder 321 can be used to radially limit the stator assembly 41 to ensure the accuracy of the installation position of the stator assembly 41. And fixedly connecting the stator assembly 41 to the damping cylinder 321 enables the stator assembly 41 to move driven by the damping cylinder 321. At the same time, sleeving the rotor assembly 42 outside the damping cylinder 321 and arranging the rotor assembly 42 between the damping cylinder 321 and the stator assembly 41 can achieve the installation of the rotor assembly 42 and make the rotor assembly 42 and the stator assembly 41 relatively distributed, improving the reliability of the movement of the rotor assembly 42 under the action of the stator assembly 41.

[0083] In some embodiments, the damping spring 312 is coaxially arranged with both the stator assembly 41 and the rotor assembly 42.

[0084] Specifically, as Figure 2 shown, sleeving the damping spring 312 outside the damping cylinder 321 and sleeving the stator assembly 41 outside the damping cylinder 321 can coaxially arrange the damping spring 312 and the stator assembly 41. Arranging the rotor assembly 42 between the damping cylinder 321 and the stator assembly 41 can coaxially arrange the rotor assembly 42 and the stator assembly 41. Thus, the damping spring 312 can be coaxially arranged with both the stator assembly 41 and the rotor assembly 42, which is beneficial to reducing the overall volume of the shock absorber assembly 100, reducing the space occupied by the shock absorber assembly 100 on the vehicle, and facilitating the installation of the shock absorber assembly 100 on the vehicle.

[0085] In some embodiments, the shock absorber assembly 100 further includes a body connector 1 and a wheel connector 2, and the body connector 1 and the wheel connector 2 are spaced apart along a first direction; wherein, one end of the shock absorber spring 312 and the other end of the damper rod 311 are both connected to the body connector 1, the stator assembly 41 is connected to the wheel connector 2, and the other end of the shock absorber spring 312 is connected to the rotor assembly 42.

[0086] Specifically, the body connector 1 is used to connect the shock absorber assembly 100 to the body, and the wheel connector 2 is used to connect the shock absorber assembly 100 to the wheel, thereby enabling the installation of the shock absorber assembly 100 on the vehicle. Connecting the shock absorber assembly 100 to both the body and the wheel simultaneously can improve the reliability and stability of the installation of the shock absorber assembly 100. At the same time, by spacing the body connector 1 and the wheel connector 2 apart along the first direction, the body and the wheel can be respectively connected to both ends of the shock absorber assembly 100, that is, the shock absorber assembly 100 can be disposed between the body and the wheel to absorb the impact and vibration received by the wheel when the vehicle is traveling on an uneven road, so as to reduce the impact and vibration received by the body and the passengers, and improve the driving stability and riding comfort of the vehicle.

[0087] It should be noted that the body is disposed above the wheel, that is, the body connector 1 is disposed above the wheel connector 2, that is, the first direction is the up-down direction of the vehicle, and the body connector 1 includes an upper tower top 11 and an upper support seat 12. The upper tower top 11 is used to connect the shock absorber assembly 100 to the body, and the upper support seat 12 is used to support the shock absorber spring 312 from above and axially limit it. The shock absorber spring 312 is sleeved outside the damper cylinder 321, and the damper cylinder 321 is used to radially limit the shock absorber spring 312 to effectively improve the accuracy of the installation position of the shock absorber spring 312, and thus improve the reliability of the operation of the shock absorber spring 312.

[0088] In addition, the stator assembly 41 is connected to the wheel connector 2, and the stator assembly 41 is relatively fixed to the damper cylinder 321, so that the vibration and impact received by the wheel can be transmitted to the damper cylinder 321 through the wheel connector 2, causing relative movement between the damper cylinder 321 and the damper rod 311. One end of the shock absorber spring 312 and the other end of the damper rod 311 are both connected to the body connector 1, and one end of the shock absorber spring 312 and the other end of the damper rod 311 are relatively fixed, so that the damper rod 311 can drive the shock absorber spring 312 to move together when moving relative to the damper cylinder 321, so as to reduce the vibration and impact transmitted to the body through the body connector 1.

[0089] That is to say, when the vehicle is traveling on an uneven road surface, the wheels will be subjected to impacts and vibrations from the ground and move up and down under the action of the impacts and vibrations of the ground. This movement is transmitted to the damper cylinder 321 through the wheel connecting member 2 and drives the damper cylinder 321 to move together. At this time, the damper rod 311 can move relative to the damper cylinder 321 and drives the shock-absorbing spring 312 to move together. Among them, when the damper rod 311 moves, it will push the damping liquid 33 to flow, so that the damping liquid 33 provides a damping force to the damper rod 311 to reduce the impacts and vibrations transmitted to the vehicle body through the damper rod 311. And the shock-absorbing spring 312 can also absorb a part of the vibrations and impacts during the movement process, further reducing the vibrations and impacts transmitted to the vehicle body, realizing the shock-absorbing function of the shock absorber assembly 100, and improving the ride comfort and driving stability of the vehicle.

[0090] Moreover, by connecting the other end of the shock-absorbing spring 312 to the mover assembly 42, that is, connecting the lower end of the shock-absorbing spring 312 to the mover assembly 42, when the vehicle vibrates, by energizing the stator assembly 41, the mover assembly 42 can move under the action of the stator assembly 41, and the movement is transmitted to the vehicle body through the shock-absorbing spring 312 to actively adjust the height of the vehicle body, realizing the height adjustment function of the shock absorber assembly 100.

[0091] In some embodiments, the adjusting structure 4 is configured as a linear motor.

[0092] Specifically, the linear motor is used to convert electrical energy into mechanical energy of linear motion. By configuring the adjusting structure 4 as a linear motor, the mover assembly 42 can move linearly under the action of the stator assembly 41. And in the linear motor, the stator assembly 41 and the mover assembly 42 can be spaced apart, that is, there can be an air gap between the stator assembly 41 and the mover assembly 42, realizing contactless driving to reduce the wear of the stator assembly 41 and the mover assembly 42 and extend the service life of the adjusting structure 4.

[0093] In addition, it should be noted that the mover assembly 42 can be configured as a mover shaft to transmit power through the mover shaft. By passing the mover shaft through the stator assembly 41 and the mounting bracket 9, the installation of the mover shaft can be realized, and the mover shaft can move relative to the stator assembly 41, that is, the mover assembly 42 can drive the shock-absorbing spring 312 to move axially relative to the damper cylinder 321, and then the height adjustment function of the shock absorber assembly 100 can be realized.

[0094] Among them, as Figures 2 - 3 shown, the adjusting structure 4 further includes a motor housing 43. The stator assembly 41 is arranged in the motor housing 43 and is closely attached to the motor housing 43. The adjusting structure 4 is fixedly connected to the damper cylinder 321 through the motor housing 43.

[0095] In some embodiments, one of the stator assembly 41 and the rotor assembly 42 includes a permanent magnet, and the other includes a winding core.

[0096] Specifically, the rotor assembly 42 can move under the action of the stator assembly 41. The stator assembly 41 can be a permanent magnet and the rotor assembly 42 can be a winding core, or the stator assembly 41 can be a winding core and the rotor assembly 42 can be a permanent magnet. The interaction between the stator assembly 41 and the rotor assembly 42 can be realized through electromagnetic action, and the functions of the stator assembly 41 and the rotor assembly 42 can be interchanged. For the convenience of description, the rotor assembly 42 can be connected to the support base 6, and the stator assembly 41 can be connected to the damper cylinder 321.

[0097] Among them, when the stator assembly 41 is a permanent magnet and the rotor assembly 42 is a winding core, the driving force of the adjusting structure 4 can be increased. When the stator assembly 41 is a winding core and the rotor assembly 42 is a permanent magnet, it is convenient to arrange the heat dissipation scheme for the adjusting structure 4.

[0098] It should be noted that in the embodiments as Figures 1 - 6 shown, the structure is arranged with the stator assembly 41 as a permanent magnet and the rotor assembly 42 as a winding core as an example.

[0099] In some embodiments, the adjusting structure 4 is configured as a motor. When the moving part 31 moves relative to the fixed part 32, it is also adapted to drive the rotor assembly 42 to move relative to the stator assembly 41, and when the rotor assembly 42 moves relative to the stator assembly 41, the motor generates electricity.

[0100] Specifically, the adjusting structure 4 is used to drive the moving part 31 to move relative to the fixed part 32 to adjust the relative position relationship between the two. The adjusting structure 4 can be configured as a motor, and the driving force generated during the operation of the motor is used to drive the moving part 31 to adjust the height of the moving part 31, realizing the height adjustment function of the shock absorber assembly 100. Moreover, when the moving part 31 moves relative to the fixed part 32, it can also drive the rotor assembly 42 to move relative to the stator assembly 41. When the rotor assembly 42 moves relative to the stator assembly 41, the stator assembly 41 can generate current, that is, the motor can generate electricity. Through this process, the vibration energy of the vehicle can be recovered, that is, the energy recovery function of the shock absorber assembly 100 can be realized.

[0101] That is to say, when the vehicle vibrates, the movable part 31 in the shock absorber 3 can move relative to the fixed part 32 to buffer the vibration energy of the vehicle, realizing the shock absorption function of the shock absorber assembly 100. Moreover, the movable part 31 can be driven by a motor to move relative to the fixed part 32 to actively adjust the height of the movable part 31, realizing the height adjustment function of the shock absorber assembly 100. In addition, during the movement of the movable part 31 relative to the fixed part 32, the mover assembly 42 can also be driven to move relative to the stator assembly 41, enabling the motor to generate electricity, that is, realizing the energy recovery function of the shock absorber assembly 100. Thus, the shock absorber assembly 100 can realize multiple functions, increasing the application range of the shock absorber assembly 100.

[0102] In some embodiments, there are multiple adjusting structures 4, and the multiple adjusting structures 4 are spaced apart in the circumferential direction of the shock absorber 3.

[0103] Specifically, the number of the adjusting structures 4 provided can be at least one, that is, it can be one, two, three or more. For example, Figures 1 - 4 The schematic structural diagram shows only one adjusting structure 4 provided, and the adjusting structure 4 can be arranged outside the shock absorber 3. As shown in Figures 5 - 6 The schematic structural diagram shows multiple adjusting structures 4 provided at the same time. The multiple adjusting structures 4 can be spaced apart in the circumferential direction of the shock absorber 3, so as to jointly drive the shock absorber spring 312 to move by the multiple mover assemblies 42 in the multiple adjusting structures 4, or enable the shock absorber spring 312 to drive the multiple mover assemblies 42 to move at the same time. Among them, when multiple adjusting structures 4 are provided at the same time, it is necessary to keep the multiple adjusting structures 4 balanced in the circumferential direction of the shock absorber 3 to improve the stability and reliability of the movement of the shock absorber spring 312.

[0104] In addition, it should be noted that the shock absorber assembly 100 of the present application can realize the active adjustment of the vehicle body height, and can also realize the active adjustment of the vehicle body height by installing a driving motor 4 in the hydraulic damper 3 for passively adjusting the vehicle body height. The installation method is simple, the component sources are extensive, and it is easy to apply and implement.

[0105] The present utility model also proposes a vehicle.

[0106] The vehicle according to the embodiment of the present utility model is provided with the shock absorber assembly 100 described in any one of the above. By providing the shock absorber 3, the vibration during the vehicle bumping can be buffered, realizing the shock absorption function of the shock absorber assembly 100. By providing the adjusting structure 4, the overall height of the shock absorber 3 can be adjusted, that is, the height of the vehicle body can be actively adjusted, realizing the height adjustment function of the shock absorber assembly 100, enabling the vehicle to adapt to different driving road conditions, effectively improving the passing performance and riding comfort of the vehicle, and being beneficial to improving user satisfaction.
