[0052] The following is for reference. Figures 1-7 A shock absorber assembly 100 for a vehicle according to an embodiment of the present invention is described.

[0053] Reference Figure 1 , Figure 2 and Figure 3 According to an embodiment of the present invention, a vehicle shock absorber assembly 100 includes: a housing 1, a damping mechanism, and a sensor. At least a portion of the damping mechanism is disposed within the housing 1, and the sensor is also disposed within the housing 1. The sensor is configured to detect position information of the moving parts of the damping mechanism.

[0054] The housing 1 is adapted to connect with the vehicle body, and the portion of the damping mechanism extending outside the housing 1 is adapted to connect with the wheel. In this embodiment, the damping mechanism includes a moving component that is movable relative to the housing 1. When the wheel is impacted, the moving component moves relative to the housing 1, and the damping mechanism generates damping. The damping of the damping mechanism can buffer the vibration transmitted from the wheel to the vehicle body, thereby reducing the vibration of the vehicle body. Sensors are used to detect the position information of the moving component of the damping mechanism to adjust the working state of the shock absorber assembly.

[0055] In this embodiment, the vibration damper assembly 100 does not require a separate housing for the sensor or a housing for fixing the sensor, which reduces the assembly steps of the vibration damper assembly 100, reduces the assembly difficulty of the vibration damper assembly 100, and lowers the cost of the vibration damper assembly 100.

[0056] According to the embodiments of the present invention, the damping mechanism and the sensor of the vehicle shock absorber assembly 100 are all disposed in the housing 1, which reduces the assembly difficulty of the shock absorber assembly 100, reduces the cost of the shock absorber assembly 100, increases the integration of the shock absorber assembly 100, reduces the space occupied by the shock absorber assembly 100 as a whole, and is conducive to the lightweighting of the shock absorber assembly 100.

[0057] In some specific embodiments, the sensor is a resolver sensor 4, which includes a resolver stator 41 and a resolver rotor 42. The resolver stator 41 and the resolver rotor 42 are inductively coupled, and the resolver rotor 42 is relatively stationary relative to the moving parts.

[0058] Specifically, the resolver rotor 42 is stationary relative to the moving parts, and the resolver stator 41 is stationary relative to the housing 1. When the moving parts move, they drive the resolver rotor 42 to move, that is, the resolver rotor 42 moves relative to the resolver stator 41. The position information of the moving parts is obtained through the sensing interaction between the resolver stator 41 and the resolver rotor 42. In this embodiment, the sensor has a simple structure, reducing the cost of the vibration damper assembly 100.

[0059] In some embodiments, the damper assembly 100 further includes a positioning component that cooperates with at least one of the resolver stator 41 and resolver rotor 42 to position the relative position between the resolver stator 41 and resolver rotor 42.

[0060] In this embodiment, the relative position between the resolver stator 41 and the resolver rotor 42 is positioned by the positioning component, ensuring the stability of the inductive engagement between the resolver stator 41 and the resolver rotor 42, so that the resolver sensor 4 can accurately obtain the position information of the moving parts and improve the reliability of the shock absorber assembly.

[0061] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of the present invention, the positioning component includes a first positioning sleeve 43 and a second positioning sleeve 44. The first positioning sleeve 43 is connected to the resolver stator 41, and the second positioning sleeve 44 is connected to the resolver rotor 42. The first positioning sleeve 43 is fixed to a stationary part (e.g., housing) of the damper assembly 100, and the second positioning sleeve 44 is fixed to a moving part.

[0062] In this embodiment, the first positioning sleeve 43 is used to position the resolver stator 41. The first positioning sleeve 43 is connected to the resolver stator 41 and fixed to the stationary part of the damper assembly 100, so that the resolver stator 41 is stationary relative to the stationary part of the damper assembly 100, thereby ensuring the accuracy of the resolver sensor 4 detection.

[0063] The second positioning sleeve 44 is used to position the resolver rotor 42. The second positioning sleeve 44 is connected to the resolver rotor 42 and fixed to the moving part, so that the resolver rotor 42 is stationary relative to the moving part, thereby ensuring the accuracy of the resolver sensor 4 detection.

[0064] Reference Figure 3 , Figure 5 and Figure 7 In some embodiments of the present invention, the axial height of the second positioning sleeve 44 is greater than the axial height of the first positioning sleeve 43.

[0065] Because there is a height difference between the installation positions of the first positioning sleeve and the second positioning sleeve, in this embodiment, the axial height of the second positioning sleeve 44 is greater than the axial height of the first positioning sleeve 43, thereby making the resolver stator 41 and the resolver rotor 42 located at the same position in the height direction of the damper assembly, reducing the distance between the resolver stator 41 and the resolver rotor 42, improving the detection accuracy of the resolver sensor 4, and improving the accuracy of the resolver sensor 4.

[0066] In some further embodiments, the axial end face of the second positioning sleeve 44 is provided with a first positioning element, and the resolver rotor 42 is provided with a second positioning element, with the first positioning element and the second positioning element being inserted into each other.

[0067] In this embodiment, the initial positioning of the resolver rotor 42 and the second positioning sleeve 44 is achieved by the insertion and cooperation of the first positioning member and the second positioning member, which makes it easier for the staff to fix the resolver rotor 42 and the second positioning sleeve 44 with fasteners.

[0068] Reference Figure 4 and Figure 5 In some specific embodiments, the first positioning element is formed as a first protrusion 441, which is located on the end face of the second positioning sleeve 44 facing away from the rotor assembly 22. The second positioning element is a first groove 421, which is located on the side of the resolver rotor 42 facing the second positioning sleeve 44. The first protrusion 441 is inserted into the first groove 421.

[0069] In this embodiment, the first positioning member and the second positioning member have simple structures, which reduces the cost of the shock absorber assembly 100.

[0070] In other specific embodiments, the first positioning member is formed as a first groove 421, which is located on the end face of the second positioning sleeve 44 opposite to the rotor assembly 22. The second positioning member is formed as a first protrusion 441, which is located on the side of the resolver rotor 42 facing the second positioning sleeve 44. The first protrusion 441 is inserted into the first groove 421.

[0071] In some embodiments of the present invention, a plurality of first positioning elements are provided, and the plurality of first positioning elements are evenly distributed along the circumference of the second positioning sleeve 44. A plurality of second positioning elements are also provided, and the plurality of second positioning elements are evenly distributed along the circumference of the resolver rotor 42. The plurality of first positioning elements correspond one-to-one with the plurality of second positioning elements.

[0072] In this embodiment, multiple first positioning members are evenly distributed along the circumference of the second positioning sleeve 44, and multiple second positioning members are evenly distributed along the circumference of the resolver rotor 42. Therefore, when connecting the resolver rotor 42 and the second positioning sleeve 44, only a slight rotation of a certain angle is needed to insert and engage the first and second positioning members, further improving the convenience of connecting the resolver rotor 42 and the second positioning sleeve 44.

[0073] Reference Figure 4 and Figure 5 In some embodiments of the present invention, the resolver rotor 42 is provided with a first connecting hole 422, which is a through hole, and the second positioning sleeve 44 is provided with a second connecting hole 442, which is a threaded hole.

[0074] In this embodiment of the application, when connecting the resolver rotor 42 and the second positioning sleeve 44, the first positioning member and the second positioning member are first inserted and matched to realize the positioning of the resolver rotor 42 relative to the second positioning sleeve 44. Then, the fastener passes through the first connecting hole 422 and is threadedly connected to the second connecting hole 442, thereby fixing the resolver rotor 42 on the second positioning sleeve 44.

[0075] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the first positioning sleeve 43 is fixed to the inner peripheral wall of the housing 1.

[0076] In this embodiment, the first positioning sleeve 43 is fixed to the inner peripheral wall of the housing 1, which can make the first positioning sleeve 43 stationary relative to the stationary part of the shock absorber assembly 100. The installation method is simple and reduces the cost of the shock absorber assembly 100.

[0077] Reference Figure 3 , Figure 6 and Figure 7In some embodiments of the present invention, the outer peripheral wall of the first positioning sleeve 43 is provided with a plurality of fixing protrusions 431, and the inner peripheral wall of the housing 1 is provided with a plurality of fixing grooves 12. The plurality of fixing protrusions 431 and the plurality of fixing grooves 12 cooperate to fix and position the first positioning sleeve 43.

[0078] In this embodiment, the positioning of the first positioning sleeve 43 and the housing 1 can be achieved simply by inserting the fixing protrusion 431 into the fixing groove 12. The installation method of the first positioning sleeve 43 is simple, which reduces the cost of the shock absorber assembly 100.

[0079] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of the present invention, the damping mechanism includes a drive motor 2 and a transmission assembly 3. A mounting cavity 11 is provided within the housing 1. The drive motor 2 is at least partially disposed within the mounting cavity 11, and the transmission assembly 3 is at least partially disposed within the mounting cavity 11. The drive motor 2 includes a stator assembly 21 and a rotor assembly 22. The stator assembly 21 and the rotor assembly 22 are coupled together to drive the rotor assembly 22 to rotate. The transmission assembly 3 includes a rotating member 31 and a transmission member 32. The rotor assembly 22 is connected to the rotating member 31 to drive the rotating member 31 to rotate. The rotating member 31 and the transmission member 32 cooperate to drive the transmission member 32 to reciprocate. At least a portion of the transmission member 32 extends outside the housing 1.

[0080] In some application scenarios of this application, the housing 1 is suitable for connection with the vehicle body, and the part of the transmission component 32 extending out of the housing 1 is suitable for connection with the wheel. When the shock absorber assembly 100 is working, the stator assembly 21 drives the rotor assembly 22 to rotate, the rotor assembly 22 drives the rotating component 31 to rotate to drive the transmission component 32 to move, and the transmission component 32 drives the wheel to move relative to the vehicle body, thereby adjusting the relative distance between the vehicle body and the wheel to improve the smoothness of vehicle driving.

[0081] It should be noted that the drive motor 2 can adjust its output force according to the impact force on the vehicle to adjust the damping magnitude of the damping mechanism. For example, when the impact force is large, the output force of the drive motor 2 can be increased to increase the damping, thereby ensuring that the shock absorber assembly 100 can achieve effective vibration reduction. When the impact force is small, the output force of the drive motor 2 can be reduced to reduce the damping, so that the transmission component 32 can have sufficient buffer stroke.

[0082] In this embodiment, the drive motor 2 is disposed inside the housing 1, which improves the integration of the vibration damper assembly 100, reduces the space occupied by the vibration damper assembly 100 as a whole, and in this embodiment, the drive motor 2 does not need to be separately disposed of as a motor housing, and does not need to be fixed as a motor housing, which reduces the assembly steps of the vibration damper assembly 100, reduces the assembly difficulty of the vibration damper assembly 100, and reduces the cost of the vibration damper assembly 100.

[0083] In this embodiment, the sensor is disposed within the mounting cavity 11 and is configured to detect the position information of the rotor assembly 22. The sensor determines the operating state of the damper assembly 100 by acquiring the position information of the rotor assembly 22. For example, the sensor can detect the rotational speed / acceleration of the rotor assembly 22 to determine the magnitude of the impact force on the wheel, thereby controlling the output force of the drive motor 2 to adjust the damping magnitude and improve the vibration reduction effect of the damper assembly 100.

[0084] In some embodiments of the present invention, the sensor is configured as a resolver sensor 4, which is disposed in the mounting cavity 11. The resolver sensor 4 includes a resolver stator 41 and a resolver rotor 42. The resolver stator 41 is relatively stationary with respect to the stator assembly 21, and the resolver rotor 42 is relatively stationary with respect to the rotor assembly 22. The resolver stator 41 and the resolver rotor 42 are inductively coupled.

[0085] When the damper assembly 100 is working, the stator assembly 21 drives the rotor assembly 22 to rotate. The rotor assembly 22 rotates relative to the stator assembly 21. Because the resolver stator 41 is relatively stationary with respect to the stator assembly 21, and the resolver rotor 42 is relatively stationary with respect to the rotor assembly 22, when the rotor assembly 22 rotates relative to the stator assembly 21, the resolver rotor 42 rotates relative to the resolver stator 41. Through the induced engagement between the resolver stator 41 and the resolver rotor 42, the rotation angle of the resolver rotor 42 relative to the resolver stator 41 is obtained, thereby obtaining the position information of the moving parts of the damping mechanism, so as to adjust the working state of the damper assembly.

[0086] In some embodiments of the present invention, the rotor assembly 22 is fitted onto the rotating member 31, and the resolver sensor 4 is located radially outside the rotating member 31.

[0087] In this embodiment, the rotor assembly 22 is fitted onto the rotating component 31. The connection between the rotor assembly 22 and the rotating component 31 is simple, and the rotor assembly 22 can directly drive the rotating component 31 to rotate when it rotates. Furthermore, in this embodiment, the connection between the rotor assembly 22 and the rotating component 31 reduces the space occupied by the transmission between the rotor assembly 22 and the rotating component 31, which is beneficial to the miniaturization of the shock absorber assembly 100.

[0088] It should be understood that the connection between the rotor assembly 22 and the rotating component 31 can also be a gear drive, belt drive, etc., as long as the rotor assembly 22 can drive the rotating component 31 to rotate.

[0089] In this embodiment, the resolver sensor 4 is also located on the radial outer side of the rotating member 31, making full use of the space on the radial outer side of the rotating member 31, which is beneficial to the miniaturization of the shock absorber assembly 100.

[0090] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of the present invention, the end of the rotating member 31 protrudes from the rotor assembly 22, and in the radial direction of the transmission member 32, the resolver sensor 4 is fitted over the portion of the rotating member 31 that protrudes from the rotor assembly 22.

[0091] In this embodiment, the resolver sensor 4 is located on the radially outer side of the portion of the rotating member 31 that protrudes from the rotor assembly 22, making full use of the space on the radially outer side of the portion of the rotating member 31 that protrudes from the rotor assembly 22, and further improving the integration of the resolver sensor 4.

[0092] In some embodiments of the present invention, the resolver sensor 4 is disposed at the end of the drive motor 2 in the axial direction of the transmission member 32.

[0093] Due to space constraints, after the drive motor 2 is installed in the mounting cavity 11, some space is usually left at the end of the drive motor 2. This application makes full use of the space at the end of the drive motor 2 by placing the resolver sensor 4 at the end of the drive motor 2, thereby further improving the integration of the resolver sensor 4.

[0094] Furthermore, in this embodiment, the resolver sensor 4 is located at the end of the drive motor 2, which restricts the displacement of the resolver sensor 4 in the axial direction of the rotating member 31 and improves the stability of the resolver sensor 4.

[0095] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of the present invention, the damper assembly 100 further includes a first positioning sleeve 43 and a second positioning sleeve 44. The first positioning sleeve 43 is connected to the resolver stator 41 and is fixed to the housing 1 and / or the stator assembly 21. The second positioning sleeve 44 is connected to the resolver rotor 42 and is fixed to the rotor assembly 22 and / or the rotating member 31.

[0096] In this embodiment, the first positioning sleeve 43 is used to position the resolver stator 41. The first positioning sleeve 43 is connected to the resolver stator 41 and is fixed to the housing 1 and / or the stator assembly 21, thereby making the resolver stator 41 stationary relative to the stator assembly 21. It should be noted that the first positioning sleeve 43 may be fixed to the housing 1, fixed to the stator assembly 21, or partially fixedly connected to the housing 1 and partially fixedly connected to the stator assembly 21. This application does not limit this.

[0097] The second positioning sleeve 44 is used to position the resolver rotor 42. The second positioning sleeve 44 is connected to the resolver rotor 42 and is fixed to the rotor assembly 22 and / or the rotating component 31, thereby making the resolver rotor 42 stationary relative to the rotor assembly 22. It should be noted that the second positioning sleeve 44 may be fixed to the rotating component 31, or it may be fixed to the rotor assembly 22, or one part may be fixedly connected to the rotating component 31 and the other part may be fixedly connected to the rotor assembly 22. This application does not limit this.

[0098] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of the present invention, the first positioning sleeve 43 is located on the end face of the stator assembly 21, and the second positioning sleeve 44 is located on the end face of the rotor assembly 22. The first positioning sleeve 43 is provided with a first mounting surface for mounting the resolver stator 41, and the second positioning sleeve 44 is provided with a second mounting surface for mounting the resolver rotor 42. The height difference between the first mounting surface and the second mounting surface is ≤5mm.

[0099] In this embodiment, the height difference between the first mounting surface and the second mounting surface is defined, which improves the ease of installation of the resolver stator 41 and the resolver rotor 42, reduces the distance between the resolver stator 41 and the resolver rotor 42, and helps to improve the accuracy of induction between the resolver stator 41 and the resolver rotor 42.

[0100] In some specific embodiments, the first mounting surface and the second mounting surface are at the same height, which further reduces the distance between the resolver stator 41 and the resolver rotor 42 and improves the accuracy of the induction between the resolver stator 41 and the resolver rotor 42.

[0101] Reference Figure 3 , Figure 5 and Figure 7 In some embodiments of the present invention, the axial height of the second positioning sleeve 44 is greater than the axial height of the first positioning sleeve 43, and the second positioning sleeve 44 is fixed to the rotating member 31 and supported at the end of the rotor assembly 22.

[0102] Because the length of the stator assembly 21 is greater than the length of the rotor assembly 22 in the axial direction of the rotor assembly 22, there is a distance difference between the end of the stator assembly 21 and the end of the rotor assembly 22 in the axial direction of the rotor assembly 22.

[0103] The resolver stator 41 is positioned at the end of the stator assembly 21 by the first positioning sleeve 43, and the resolver rotor 42 is positioned at the end of the rotor assembly 22 by the second positioning sleeve 44. In order to avoid a distance difference between the resolver stator 41 and the resolver rotor 42 in the axial direction of the rotor assembly 22, in this embodiment, the axial height of the second positioning sleeve 44 is greater than the axial height of the first positioning sleeve 43, thereby reducing the distance between the first mounting surface and the second mounting surface, so that the resolver stator 41 and the resolver rotor 42 can be at the same height, reducing the distance between the resolver stator 41 and the resolver rotor 42, improving the detection accuracy of the resolver sensor 4, improving the accuracy of the resolver sensor 4, and also improving the ease of installation of the resolver sensor 4.

[0104] Furthermore, in this embodiment, the second positioning sleeve 44 is fixed to the rotating member 31 and supported at the end of the rotor assembly 22. The movement of the second positioning sleeve 44 is restricted by the end of the rotor assembly 22, thereby improving the stability of the second positioning sleeve 44.

[0105] In this embodiment, the second positioning sleeve 44 is fixed to the rotating member 31, thus achieving a stationary position of the second positioning sleeve 44 relative to the rotor assembly 22. This eliminates the need to connect the second positioning sleeve 44 to the rotor assembly 22 and avoids altering the structure of the rotor assembly 22, thereby reducing the cost of the vibration damper assembly 100.

[0106] In some embodiments of the present invention, the second positioning sleeve 44 is fitted over the rotating member 31 and is interference-fitted with the rotating member 31.

[0107] In this embodiment, the connection between the second positioning sleeve 44 and the rotating component 31 is simple, which reduces the cost of the shock absorber assembly 100. In addition, it reduces the space occupied by the connection between the second positioning sleeve 44 and the rotating component 31, and further improves the integration of the resolver sensor 4.

[0108] In other embodiments, the second positioning sleeve 44 may be connected to the rotating member 31 by fasteners, or to the rotor assembly 22 by fasteners, such as bolts or screws.

[0109] In some embodiments of the present invention, the resolver rotor 42 is connected to the second positioning sleeve 44 by fasteners, which are bolts or screws, resulting in high connection stability and low cost.

[0110] In some embodiments of the present invention, the housing 1 is provided with a removable top cover 13, and the resolver sensor 4 is located between the top cover 13 and the end of the drive motor 2.

[0111] When the resolver sensor 4 needs maintenance, the top cover 13 on the housing 1 can be removed to repair the structure inside the mounting cavity 11, reducing the maintenance cost of the resolver sensor 4.

[0112] Furthermore, in this embodiment, the resolver sensor 4 is located between the top cover 13 and the end of the drive motor 2, rather than near the transmission assembly 3, which reduces the envelope space of the portion of the shock absorber assembly 100 with the transmission assembly 3 and reduces the possibility of the shock absorber assembly 100 interfering with other structures of the vehicle body.

[0113] In some specific embodiments, the top cover 13 is connected to the housing 1 by a plurality of fasteners, which can be screws or bolts, resulting in high connection stability and low cost.

[0114] In some specific embodiments, the outer peripheral wall of the first positioning sleeve 43 is provided with a plurality of fixing protrusions 431, and the inner peripheral wall of the housing 1 is provided with a plurality of fixing grooves 12. The plurality of fixing protrusions 431 and the plurality of fixing grooves 12 are correspondingly engaged to fix and position the first positioning sleeve 43. The housing 1 is provided with a detachable top cover 13, and the resolver sensor 4 is located between the top cover 13 and the end of the drive motor 2. The top cover 13 abuts against the first positioning sleeve 43 to prevent the fixing protrusions 431 from disengaging from the fixing grooves 12.

[0115] In this embodiment, the fixing method of the first positioning sleeve 43 is simple, which reduces the cost of the shock absorber assembly 100.

[0116] Reference Figure 4 and Figure 7 In some embodiments of the present invention, the resolver stator 41 is provided with a third connecting hole 411, which is a through hole, and the first positioning sleeve 43 is provided with a fourth connecting hole 432, which is a threaded hole.

[0117] When connecting the resolver stator 41 to the first positioning sleeve 43, the fastener first passes through the third connecting hole 411 and then is threaded into the fourth connecting hole 432.

[0118] In this embodiment, the connection between the resolver stator 41 and the first positioning sleeve 43 is simple, which reduces the cost of the damper assembly 100.

[0119] In some embodiments of the present invention, a guide structure is provided within the rotating component, and the transmission component cooperates with the guide structure to reciprocate relative to the rotating component. When the rotating component rotates, the guide structure guides the transmission component to move, simplifying the transmission method and reducing the cost of the shock absorber assembly.

[0120] In some embodiments of the present invention, the rotating component can be formed as a cylindrical cam. Since the cylindrical cam can precisely control the movement trajectory, speed and acceleration of the transmission component through its specific profile shape, the use of a cylindrical cam can effectively reduce vibration during vehicle operation, thereby improving the stability and comfort of the vehicle during operation and thus enhancing the driving experience.

[0121] Furthermore, the cylindrical cam design allows power to be directly transmitted to the transmission components, reducing intermediate transmission links. This improves the overall efficiency and operational stability of the damping mechanism. The use of a cylindrical cam also makes the structure of the damping mechanism relatively simple and space-saving, facilitating complex motion control within a limited space and reducing the maintenance and replacement difficulty of the shock absorber assembly 100.

[0122] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of the present invention, the rotating member 31 can be constructed as a hollow columnar structure, and a guide groove is formed on the inner wall of the rotating member 31. The guide groove is constructed as a thread, and the transmission member 32 is installed in the rotating member 31. The transmission member 32 is used to guide and cooperate with the guide groove. When the rotor assembly 22 drives the rotating member 31 to rotate, the rotating member 31 can drive the transmission member 32 to move axially through the guide groove, so that the transmission member 32 can reciprocate relative to the rotating member 31.

[0123] The above settings can simplify the structure of the transmission component 3 and make the movement of the transmission component 32 more stable, thereby improving the reliability of the shock absorber assembly 100.

[0124] In some embodiments of the present invention, the two ends of the rotating member 31 are rotatably supported on the housing 1 by means of mating bearings 312, which effectively improves the smoothness and stability of the rotation of the rotating member 31.

[0125] In some further embodiments, the opposite sidewalls of the housing 1 are provided with support protrusions 14, and the bearings 312 are mounted to the support protrusions 14 so that the end faces of the rotating members 31 are spaced apart from the inner walls of the housing 1.

[0126] The above-mentioned design avoids the inner wall of housing 1 from hindering the rotation of the transmission components, which helps to improve the motion stability of the transmission components and improves the reliability of the shock absorber assembly 100.

[0127] In some embodiments of the present invention, the transmission assembly 3 further includes a follower 33, and there are multiple followers 33, such as two, three or more. The multiple followers 33 are arranged circumferentially spaced along the transmission member 32. The followers 33 are connected to the transmission member 32 and protrude from the outer peripheral wall of the transmission member 32. The multiple followers 33 are respectively slidably engaged with the guide groove so that the rotating member 31 can drive the transmission member 32 to move through the follower 33.

[0128] The above settings simplify the structure of the transmission component 32, reduce the processing difficulty of the transmission component 32, and improve the practicality of the shock absorber assembly 100.

[0129] In some embodiments of the present invention, the follower 33 includes a follower rod 331 and a support bearing 332. One end of the follower rod 331 along the length direction is fixed to the transmission member 32, and the support bearing 332 is installed at the other end of the follower rod 331 along the length direction. The support bearing 332 is rotatable relative to the follower rod 331 and is movably supported in the guide groove.

[0130] By setting the above, the friction between the follower 33 and the guide groove can be reduced, so that the rotating part 31 can better drive the transmission part 32 to move, thereby improving the motion stability of the transmission part 32 and enhancing the vibration reduction effect of the damper assembly 100.

[0131] In some embodiments of the present invention, a threaded hole may be provided on the outer peripheral wall of the transmission member 32 corresponding to the follower 33, the follower rod 331 is cylindrical, one end of the follower rod 331 is provided with an external thread, and the follower rod 331 can be screwed into the threaded hole through the external thread to detachably install the follower 33 on the transmission member 32.

[0132] The above settings reduce the installation difficulty of the follower 33, improve the installation stability of the follower 33, and make the follower 33 easy to replace, which is beneficial for subsequent maintenance and improves the practicality of the shock absorber assembly 100.

[0133] Of course, the transmission component 32 may also be provided with a snap-fit ​​hole, and the follower rod 331 may be snapped into the snap-fit ​​hole. The present invention does not limit this.

[0169] Because there is a height difference between the installation positions of the first positioning sleeve and the second positioning sleeve, in this embodiment, the axial height of the second positioning sleeve 44 is greater than the axial height of the first positioning sleeve 43, so that the resolver stator 41 and the resolver rotor 42 can be located at the same position, reducing the distance between the resolver stator 41 and the resolver rotor 42, improving the detection accuracy of the resolver sensor 4, and improving the accuracy of the resolver sensor 4.

[0170] In some further embodiments, the axial end face of the second positioning sleeve 44 is provided with a first positioning element, and the resolver rotor 42 is provided with a second positioning element, with the first positioning element and the second positioning element being inserted into each other.

A plurality of second positioning elements are also provided, and the plurality of second positioning elements are evenly distributed along the circumference of the resolver rotor 42.

[0176] In this embodiment, multiple first positioning members are evenly distributed along the circumference of the second positioning sleeve 44, and multiple second positioning members are evenly distributed along the circumference of the resolver rotor 42. Therefore, when connecting the resolver rotor 42 and the second positioning sleeve 44, only a slight rotation of a certain angle is needed to insert and engage the first and second positioning members, further improving the convenience of connecting the resolver rotor 42 and the second positioning sleeve 44.
