Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a strut assembly and a vehicle. Background Technology

[0002] Currently, in order to meet users' needs for vehicle use, electric struts are used on some opening and closing components of vehicles, such as the tailgate, sliding side doors, hood, or charging port cover. Electric struts can realize the automatic opening and closing and position holding of these components, thereby improving the user experience of the vehicle.

[0003] During the use of electric struts, in order to prevent the electric struts from twisting, it is usually necessary to limit and prevent twisting of the lead screw and nut assembly in the electric struts. During operation, the limit and prevent twisting structure in the lead screw and nut assembly will generate lateral friction force, which can easily cause friction noise. This is not conducive to improving the quality of electric struts, and thus is not conducive to improving the overall quality of the vehicle. Utility Model Content

[0004] In view of this, this application aims to propose a strut assembly that is beneficial to improving the overall quality of the vehicle.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A strut assembly includes a sleeve assembly, a first ball socket and a second ball socket disposed at both ends of the sleeve assembly, and a drive device for driving the sleeve assembly to extend and retract. Both the first ball socket and the second ball socket are provided with ball hinge cavities and shoulders provided corresponding to the openings of the ball hinge cavities. A vehicle body ball head is rotatably provided in the ball hinge cavity of the first ball socket, and a vehicle door ball head is rotatably provided in the ball hinge cavity of the second ball socket. The shoulder on the first ball joint abuts against the two opposite sides of the body ball joint, and the shoulder on the second ball joint abuts against the two opposite sides of the door ball joint, and can restrict the torsion of the sleeve assembly around its own axis.

[0006] Furthermore, the sleeve assembly includes a first sleeve and a second sleeve fitted together with the first sleeve, the first ball socket being disposed on the first sleeve and the second ball socket being disposed on the second sleeve; the driving device includes a driving part disposed in the first sleeve and a telescopic mechanism connected to the driving part, the telescopic mechanism being able to drive the second sleeve to telescopically extend or retract relative to the first sleeve under the drive of the driving part.

[0007] Furthermore, the telescopic mechanism includes a lead screw and a telescopic tube threadedly connected to the lead screw; a retaining ring is provided in the first sleeve, the lead screw passes through the retaining ring and is connected to the drive unit, and the telescopic tube is connected to the second sleeve through the second ball socket.

[0008] Furthermore, a damper is provided between the drive unit and the retaining ring; the lead screw passes through the damper, and the lead screw is connected to both the damper and the drive end of the drive unit.

[0009] Furthermore, the damper includes a damping housing, a damping box disposed in the damping housing, and a shock-absorbing sleeve disposed between the damping box and the damping housing; the lead screw is connected to a rotating plate in the damping box, and the damping box is provided with a damping plate that applies damping force to the rotating plate.

[0010] Furthermore, the telescopic mechanism includes a bearing disposed on the lead screw, the bearing being located between the retaining ring and the damper; the damping housing has an insert section for mounting the bearing and an mounting section for mounting the damping box, the cross-sectional area of ​​the insert section being smaller than the cross-sectional area of ​​the mounting section.

[0011] Furthermore, an adapter is provided between the drive unit and the damper; the adapter is adapted to reduce vibration transmission between the drive unit and the damper, and the adapter is provided with a through hole for the lead screw to pass through.

[0012] Furthermore, the adapter includes an adapter housing and an elastomer disposed in the adapter housing; the elastomer is provided with a slot communicating with the through hole, the drive part has an output housing that accommodates the drive end, the output housing is inserted into the slot, and / or, the elastomer is provided with an abutment protrusion that abuts against the damper.

[0013] Furthermore, a washer is provided between the drive unit and the first ball socket.

[0014] Compared with related technologies, this application has the following advantages: (1) The strut assembly described in this application restricts the axial rotation of the sleeve assembly by providing a shoulder on the first and second ball sockets. This can replace the limiting anti-torsion structure in the traditional screw nut assembly, thereby solving the problem of abnormal noise caused by the lateral friction force generated by the rotation of the traditional limiting anti-torsion structure. This helps to improve the quality of the strut assembly and thus improves the overall quality of the vehicle.

[0015] (2) By including a first sleeve and a second sleeve fitted on the first sleeve in the sleeve assembly, it is convenient to arrange the first ball socket and the second ball socket, and it is convenient to prevent the sleeve assembly from rotating axially by using the shoulder to cooperate with the ball joint of the vehicle body. Furthermore, by setting the drive unit and the telescopic mechanism, it is convenient to realize the telescopic function of the strut assembly. The structure is simple and easy to design and implement.

[0016] (3) By setting the lead screw and telescopic tube, the telescopic function can be easily realized under the synergistic action of the lead screw and telescopic tube, and the lead screw can be connected to the drive unit after passing through the retaining ring. By setting the retaining ring, the installation space of the drive unit can be easily formed in the first set of tubes, which is conducive to the integrated design of the strut assembly. The structure is simple and easy to design and implement.

[0017] (4) By passing the lead screw through the damper and connecting the damper and the drive end of the drive unit, the overall structural stability of the strut assembly is improved, and the damping effect of the lead screw during rotation is also achieved, which helps to improve the running accuracy and reliability of the strut assembly and reduce noise risk.

[0018] (5) By making the damper include a damping shell, a damping box and a shock-absorbing sleeve, the shock-absorbing sleeve can effectively absorb and buffer external vibrations and impacts, reduce the vibration impact on the damping box, protect the damper, and help to further improve the quality of the damper's use, which is conducive to improving the quality of the strut assembly. Furthermore, by connecting the lead screw to the rotating plate and providing a damping plate in the damping box that can apply damping force to the rotating plate, the structure is simple, making it easy to achieve the damping effect of the strut assembly and facilitating design and implementation.

[0019] (6) By making the damping housing have an insertion section and an installation section, it is easy to install the bearing and damping box on the damping housing. Furthermore, the bearing arrangement facilitates the connection between the lead screw and the damper and helps to rotate the lead screw. The structure is simple and facilitates design and implementation.

[0020] (7) By setting the adapter, the vibration transmission between the drive unit and the damper can be reduced, thereby reducing the vibration impact on the internal structure during the use of the strut assembly. Furthermore, by setting the through hole, it is convenient to place the adapter inside the strut assembly, which is conducive to the integrated design of the strut assembly and improves the quality of use of the strut assembly.

[0021] (8) The adapter includes an adapter housing and an elastomer. The adapter housing can be used to support the overall structure of the adapter, and the elastomer can be used to achieve shock absorption and buffering. The slot on the elastomer is also convenient for the output end of the drive unit to be inserted, ensuring the stability of the transmission connection. At the same time, the setting of the abutment protrusion helps to alleviate the impact of the damper and the drive unit and reduce vibration transmission. Furthermore, the elasticity of the elastomer can also compensate for assembly errors and displacement changes of the drive unit and damper during the operation of the strut assembly, improve the overall operational reliability of the strut assembly, and achieve low noise performance of the strut assembly.

[0022] (9) By setting the gasket, it is easy to assemble the drive unit into the first sleeve, and it can improve the assembly stability of the drive unit in the strut assembly, and help to alleviate the impact between the drive unit and the body ball joint, reduce vibration transmission, and facilitate the low noise performance of the strut assembly.

[0023] This application also proposes a vehicle in which a strut assembly as described above is provided.

[0024] The vehicle described in this application, by using the strut assembly as described above, can reduce the risk of frictional noise from the vehicle's opening and closing components, thereby helping to improve the vehicle's performance. Attached Figure Description

[0026] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0030] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0032] An embodiment of the first aspect of this application provides a strut assembly, which is applied in a vehicle and is mainly used to realize the automatic opening and closing and position holding of the vehicle's opening and closing components. Furthermore, the strut assembly in this embodiment, with its innovative structural design, can reduce frictional noise during the use of the strut assembly, which helps to improve the quality of the strut assembly and thus contributes to the improvement of the overall vehicle quality.

[0033] In related technologies, in order to meet the needs of vehicle use, electric struts are used on some opening and closing components of the vehicle. These opening and closing components may include the tailgate, sliding side doors, hood, or charging port cover. The electric struts can realize the automatic opening and closing and position holding of these opening and closing components, and their performance directly affects the opening and closing smoothness, hovering reliability, and user experience of the opening and closing components.

[0034] A strut assembly typically includes a power source, a telescopic mechanism, and a damping device. The power source drives the telescopic mechanism to extend and retract, thereby opening, closing, and maintaining the position of the opening and closing components. The damping device enhances the damping effect of the strut assembly during use. However, to prevent the strut assembly from twisting during use, the lead screw and nut assembly in the electric strut usually needs to be limited and anti-twist. During operation, the anti-twist structure in the lead screw and nut assembly generates lateral friction, which can easily cause friction noise. This is detrimental to improving the quality of the electric strut and thus the overall quality of the vehicle.

[0035] In view of this, in order to overcome the shortcomings of the related technology, the strut assembly 200 in this embodiment combines... Figures 1 to 5 As shown, the overall design includes a sleeve assembly, a first ball socket 207 and a second ball socket 208 respectively disposed at both ends of the sleeve assembly, and a drive device for driving the sleeve assembly to extend and retract.

[0036] The first ball socket 207 and the second ball socket 208 are both provided with ball joint cavities and shoulders 209 provided with corresponding openings of the ball joint cavities. The ball joint cavity of the first ball socket 207 is rotatably provided with a body ball head, and the ball joint cavity of the second ball socket 208 is rotatably provided with a door ball head 300. The shoulders 209 on the first ball socket 207 abut against the two opposite sides of the body ball head, and the shoulders 209 on the second ball socket 208 abut against the two opposite sides of the door ball head 300, and can restrict the torsion of the sleeve assembly around its own axis.

[0037] At this time, as set above, the shoulder 209 provided on the first ball socket 207 and the second ball socket 208 restricts the axial rotation of the sleeve assembly, which can replace the limiting anti-torsion structure in the traditional screw nut assembly. This can solve the problem of lateral friction caused by the rotation of the traditional limiting anti-torsion structure, thereby solving the problem of friction noise caused by the use of the strut assembly 200. This helps to improve the quality of use of the strut assembly 200, thereby improving the overall quality of the vehicle.

[0038] Based on the above general introduction, specifically, the strut assembly 200 in this embodiment generally includes a sleeve assembly, a drive device, and a damping device.

[0039] The first ball joint 207 and the second ball joint 208 at both ends of the sleeve assembly are used to connect the ball joints of the vehicle body and the door, respectively. The ball joints engage with the ball hinge cavity to allow the strut assembly 200 to be installed on the vehicle. Furthermore, the drive mechanism enables the sleeve assembly to extend and retract, thereby facilitating the opening, closing, and hovering of the vehicle's tailgate. Both the sleeve assembly and the drive mechanism can be derived from existing screw and nut assemblies and drive mechanisms in electric struts, and will not be elaborated upon further here.

[0040] To improve the performance of the strut assembly 200 and enhance its stability during operation, a damping device is typically included in the strut assembly 200. One of the core structures in the damping device is the damper 100. Common dampers 100 include multi-layer flat pad stacked dampers 100, which are widely used due to their advantages such as simple assembly and easy adjustment of damping torque.

[0041] The structure of the multi-layer flat pad stacked damper 100 generally includes a rotating plate 102 and a damping plate 103. The damping effect is achieved through the friction between the rotating plate 102 and the damping plate 103. In addition to the damping device that can be used as the multi-layer flat pad stacked damper 100, the above damping device can also refer to the setting form of the damping device in the existing electric strut (such as the hydraulic damping device, etc.), which will not be described in detail here.

[0042] Regarding the aforementioned body ball joint and door ball joint 300, their structural designs are basically the same. This embodiment uses the door ball joint 300 as a specific example for explanation and description. For instance, in some exemplary embodiments, the door ball joint 300 includes a ball head and a rod. The ball head is correspondingly disposed in the ball hinge cavity of the second ball socket 208, and the rod has a limiting section 301 for connecting the ball head and a threaded section 303 for connecting the door. A boss 302 is provided between the limiting section 301 and the threaded section 303. When the strut assembly 200 has a tendency to rotate about its own axis, the shoulder 209 can abut against the limiting section 301 of the door ball joint 300, thereby preventing the strut assembly 200 from rotating about its own axis.

[0043] It is worth noting that, in actual implementation, in order to facilitate the assembly of the door ball joint 300 and the second ball socket 208, when it is assembled in the second ball socket 208, there may be a certain gap between the limiting section 301 and the shoulder 209. This gap is affected by factors such as assembly accuracy and machining accuracy. In actual implementation, this gap can be ignored. Therefore, when the strut assembly 200 has a tendency to rotate around its own axis, the rotational stroke of the strut assembly 200 caused by this gap can be ignored.

[0044] In addition to the exemplary structures described above, the body ball joint and door ball joint 300 can also refer to the structural configurations of existing vehicle door ball joints 300 and body ball joints, or refer to the various structures of ball head bolts known to those skilled in the art, which will not be elaborated here.

[0045] Continue to combine Figures 1 to 5 As shown, in some exemplary embodiments, this embodiment may, for example, include a sleeve assembly comprising a first sleeve 201 and a second sleeve 202 fitted together with the first sleeve 201, a first ball socket 207 disposed on the first sleeve 201, and a second ball socket 208 disposed on the second sleeve 202.

[0046] The above-mentioned driving device includes a driving part 203 disposed in the first sleeve 201, and a telescopic mechanism connected to the driving part 203. The telescopic mechanism can drive the second sleeve 202 to extend or retract relative to the first sleeve 201 under the drive of the driving part 203.

[0047] It is understandable that by including a first sleeve 201 and a second sleeve 202 fitted on the first sleeve 201, the arrangement of the first ball socket 207 and the second ball socket 208 is facilitated, and the sleeve assembly is prevented from rotating axially by engaging with the ball joint of the vehicle body through the shoulder 209. Furthermore, the extension and retraction function of the strut assembly 200 is easily realized through the setting of the drive unit 203 and the telescopic mechanism. The structure is simple and easy to design and implement.

[0048] In specific implementation, both the first sleeve 201 and the second sleeve 202 are cylindrical. The second sleeve 202 is located inside the first sleeve 201 and can be extended or retracted in the first sleeve 201 by the telescopic mechanism. The first ball socket 207 is located at one end of the first sleeve 201 and the second ball socket 208 is located at one end of the second sleeve 202. When the second sleeve 202 extends or retracts relative to the first sleeve 201, the first ball socket 207 can move away from or closer to the second ball socket 208.

[0049] The drive unit 203 described above may include, for example, a motor and a reducer. The telescopic mechanism is connected to the reducer via a transmission. The configuration of the drive unit 203 can be referenced, for example, the configuration of the drive unit 203 in a conventional strut assembly 200, and will not be described further here. Continuing with the discussion... Figures 1 to 5 As shown, in some exemplary embodiments, this embodiment may, for example, include a telescopic mechanism comprising a lead screw 204 and a telescopic tube 205 threadedly connected to the lead screw 204.

[0050] The first sleeve 201 is provided with a retaining ring 2010, the lead screw 204 passes through the retaining ring 2010 and is connected to the drive unit 203, and the telescopic tube 205 is connected to the second sleeve 202 through the second ball socket 208.

[0051] It is understandable that by setting the lead screw 204 and the telescopic tube 205, the telescopic function can be easily realized through the synergistic action of the lead screw 204 and the telescopic tube 205. The lead screw 204 is connected to the drive unit 203 after passing through the retaining ring 2010. The setting of the retaining ring 2010 facilitates the formation of the installation space of the drive unit 203 in the first sleeve 201, which is conducive to the integrated design of the strut assembly 200. The structure is simple and easy to design and implement.

[0052] In specific implementation, the lead screw 204 is connected to the drive unit 203 and can be driven to rotate by the drive unit 203. Preferably, a sleeve spring 206 is also provided between the first sleeve 201 and the second sleeve 202. The telescopic tube 205 is threadedly connected to the lead screw 204 and connected to the second sleeve 202. When the lead screw 204 is driven to rotate by the drive unit 203, it can drive the telescopic tube 205 to move along the axial direction of the first sleeve 201. In turn, the telescopic tube 205 can drive the second sleeve 202 to move along the axial direction of the first sleeve 201, so as to form the telescopic movement of the second sleeve 202 relative to the first sleeve 201.

[0053] Furthermore, the above-mentioned sleeve assembly also includes a third sleeve 2014 sleeved on the lead screw 204. One end of the third sleeve 2014 contacts the retaining ring 2010 of the first sleeve 201 via a flange. The third sleeve 2014 prevents interference between the sleeve spring 206 and the lead screw 204. One end of the sleeve spring 206 presses against the flange, and the other end is located at the end of the second sleeve 202 furthest from the drive unit 203. The length of the sleeve spring 206 in its natural state is greater than the length of the telescopic mechanism when it is extended to its longest state. This allows the sleeve spring 206 to continuously compress the flange of the third sleeve 2014 axially, preventing significant axial movement of the flange and thus preventing movement of the third sleeve 2014. The sleeve spring also balances the gravity of the opening and closing components, providing a buffering effect. Additionally, any structural parts not described in the above telescopic mechanism can be correspondingly configured by referring to the structures of the lead screw and nut assembly in an electric strut, which are well-known to those skilled in the art, and will not be elaborated upon here.

[0054] Continue to combine Figures 1 to 5 ,as well as Figure 9 As shown, in some exemplary embodiments, this embodiment may, for example, provide a damper 100 between the drive unit 203 and the retaining ring 2010. The lead screw 204 passes through the damper 100 and is connected to both the damper 100 and the drive end of the drive unit 203.

[0055] Understandably, by having the lead screw 204 pass through the damper 100 and connect the damper 100 to the drive end of the drive unit 203, not only is the overall structural stability of the strut assembly 200 better, but the damping effect during the rotation of the lead screw 204 can also be achieved, thereby improving the operating accuracy and reliability of the strut assembly 200 and reducing noise risk.

[0056] In specific implementation, the above damper 100 can be, for example, a multi-layer flat washer stacked damper 100. The damper 100 is provided with a through hole for the lead screw 204 to pass through, and the lead screw 204 is connected to the rotating plate 102 in the damper 100 (for example, a key connection can be used). The lead screw 204 is driven to rotate by the drive unit 203, which drives the rotating plate 102 to rotate, thereby achieving a damping effect by friction with the damping plate 103.

[0057] Continue to combine Figures 1 to 5 ,as well as Figure 9 As shown, in some exemplary embodiments, this embodiment may, for example, include a damper 100 comprising a damping housing 104, a damping box 101 disposed in the damping housing 104, and a damping sleeve 105 disposed between the damping box 101 and the damping housing 104.

[0058] The lead screw 204 is connected to the rotating plate 102 in the damping box 101, and the damping box 101 is provided with a damping plate 103 that applies damping force to the rotating plate 102.

[0059] It is understandable that by making the damper 100 include a damping housing 104, a damping box 101, and a shock-absorbing sleeve 105, the shock-absorbing sleeve 105 can effectively absorb and buffer external vibrations and impacts, reduce the vibration impact on the damping box 101, protect the damper 100, and help to further improve the performance of the damper 100, which in turn helps to improve the performance of the strut assembly 200. Furthermore, by connecting the lead screw 204 to the rotating plate 102 and providing a damping plate 103 in the damping box 101 that can apply damping force to the rotating plate 102, the structure is simple, making it easy to achieve the damping effect of the strut assembly 200 and facilitating design and implementation.

[0060] In specific implementation, the damping box 101 is disposed in the damping housing 104, and the shock-absorbing sleeve 105 is disposed between the damping box 101 and the damping housing 104. The gap between the damping housing 104 and the damping box 101 can be set to match the thickness of the shock-absorbing sleeve 105, so as to reduce the assembly gap between the damping housing 104, the damping box 101 and the shock-absorbing sleeve 105. The materials of the damping housing 104 and the shock-absorbing sleeve 105 can refer to the materials of the damping housing 104 and the shock-absorbing sleeve 105 in the existing damper 100 (such as rubber), and will not be described in detail here.

[0061] Continue to combine Figures 1 to 10 As shown, in some exemplary embodiments, this embodiment may, for example, include a telescopic mechanism comprising a bearing 2011 disposed on a lead screw 204, the bearing 2011 being located between a retaining ring 2010 and a damper 100.

[0062] The damping housing 104 has an insert section 1041 for mounting the bearing 2011 and an mounting section 1042 for mounting the damping box 101. The cross-sectional area of ​​the insert section 1041 is smaller than the cross-sectional area of ​​the mounting section 1042.

[0063] It is understandable that by having the damping housing 104 have the insertion section 1041 and the mounting section 1042, it is convenient to install the bearing 2011 and the damping box 101 on the damping housing 104. Furthermore, the bearing 2011 facilitates the connection between the lead screw 204 and the damper 100 and helps to assist the rotation of the lead screw 204. The structure is simple and facilitates design and implementation.

[0064] In practical implementation, the inner ring of the bearing 2011 is connected to the lead screw 204, and the outer ring of the bearing 2011 abuts against the insertion section 1041 of the damping housing 104 and is interference-fitted with the damping housing 104. The damping box 101 is installed inside the mounting section 1042 of the damping housing 104. Through the setting of the bearing 2011, the rotation requirements of the lead screw 204 can be met, and the lead screw 204 can be supported, thereby improving the stability of the lead screw 204 in the strut assembly 200.

[0065] Continue to combine Figures 1 to 8 As shown, in some exemplary embodiments, this embodiment may, for example, provide an adapter 2012 between the drive unit 203 and the damper 100.

[0066] The adapter 2012 is adapted to reduce vibration transmission between the drive unit 203 and the damper 100, and the adapter 2012 is provided with a through hole for the lead screw 204 to pass through.

[0067] Understandably, by setting up the adapter 2012, the vibration transmission between the drive unit 203 and the damper 100 can be reduced, thereby reducing the vibration impact on the internal structure of the strut assembly 200 during use. Furthermore, by setting up the through hole, it is convenient to arrange the adapter 2012 inside the strut assembly 200, which helps the integrated design of the strut assembly 200 and improves the quality of use of the strut assembly 200.

[0068] In a specific implementation, the adapter 2012 is located between the drive unit 203 and the damper 100. The adapter 2012 has a through hole for the lead screw 204 to pass through. The lead screw 204 passes through the adapter 2012 through the through hole, and the two sides of the adapter 2012 abut against the damper 100 and the drive unit 203 respectively. During the operation of the strut assembly 200, the adapter 2012 can absorb the vibration between the damper 100 and the drive unit 203.

[0069] Continue to combine Figures 1 to 8As shown, in some exemplary embodiments, this embodiment may, for example, make the adapter 2012 include an adapter housing 20121 and an elastomer 20122 disposed in the adapter housing 20121.

[0070] The elastic body 20122 is provided with a slot 20123 communicating with the through hole. The drive unit 203 has an output housing that accommodates the drive end. The output housing is inserted into the slot 20123. The elastic body 20122 is provided with an abutting protrusion 20124, which abuts against the damper 100.

[0071] It is understandable that the adapter 2012 includes an adapter housing 20121 and an elastomer 20122. The adapter housing 20121 can be used to support the overall structure of the adapter 2012, and the elastomer 20122 can be used to achieve a shock absorption and buffering effect. The slot 20123 provided on the elastomer 20122 also facilitates the insertion of the output end of the drive unit 203, ensuring the stability of the transmission connection. At the same time, the setting of the abutment protrusion 20124 helps to alleviate the impact between the damper 100 and the drive unit 203 and reduce vibration transmission. Furthermore, the elastic characteristics of the elastomer 20122 can also compensate for assembly errors and displacement changes of the drive unit 203 and damper 100 during the operation of the strut assembly 200, improve the overall operational reliability of the strut assembly 200, and achieve low noise performance of the strut assembly 200.

[0072] In a specific implementation, the slot 20123 on the above elastomer 20122 can be configured as a spline groove, and the output housing of the drive unit 203 can be configured as a spline to ensure the connection strength during rotation. The above abutment protrusion 20124 can be evenly arranged on the surface of the elastomer 20122 on the side near the damper 100.

[0073] Continue to combine Figures 1 to 8 As shown, in some exemplary embodiments, this embodiment may, for example, provide a washer 2013 between the drive unit 203 and the first ball socket 207.

[0074] Understandably, the installation of the washer 2013 facilitates the assembly of the drive unit 203 within the first sleeve 201, improves the assembly stability of the drive unit 203 within the strut assembly 200, helps mitigate the impact between the drive unit 203 and the body ball joint, reduces vibration transmission, and facilitates the low-noise performance of the strut assembly 200.

[0075] In practical implementation, the washer 2013 mentioned above can be, for example, the washer 2013 provided between the drive unit 203 and the first ball socket 207 in the existing strut assembly 200, and will not be described in detail here. By providing the washer 2013, the drive unit 203 can be supported, thereby improving the assembly stability of the drive unit 203 in the strut assembly 200.

[0078] The driving device includes a driving part 203 disposed in the first sleeve 201 and a telescopic mechanism connected to the driving part 203. Under the drive of the driving part 203, the telescopic mechanism can drive the second sleeve 202 to extend or retract relative to the first sleeve 201. When the first sleeve 201 and the second sleeve 202 extend or retract, the first ball socket 207 and the second ball socket 208 disposed at the ends of the first sleeve 201 and the second sleeve 202 can move closer or further away from each other. A washer 2013 is provided between the driving part 203 and the first ball socket 207.

[0079] The telescopic mechanism includes a lead screw 204 and a telescopic tube 205 threadedly connected to the lead screw 204. A retaining ring 2010 is provided in the first sleeve 201. The lead screw 204 passes through the retaining ring 2010 and is connected to the drive unit 203. The telescopic tube 205 is connected to the second sleeve 202 through a second ball socket 208. A damper 100 is provided between the drive unit 203 and the retaining ring 2010. The lead screw 204 passes through the damper 100 and is connected to both the damper 100 and the drive end of the drive unit 203.

[0080] The damper 100 includes a damping housing 104, a damping box 101 disposed in the damping housing 104, and a shock-absorbing sleeve 105 disposed between the damping box 101 and the damping housing 104. The lead screw 204 is connected to the rotating plate 102 in the damping box 101, and the damping box 101 is provided with a damping plate 103 that applies damping force to the rotating plate 102.

[0081] The telescopic mechanism includes a bearing 2011 mounted on a lead screw 204. The bearing 2011 is located between a retaining ring 2010 and a damper 100. The damping housing 104 has an insert section 1041 for mounting the bearing 2011 and an mounting section 1042 for mounting the damping box 101. The cross-sectional area of ​​the insert section 1041 is smaller than the cross-sectional area of ​​the mounting section 1042.

[0082] An adapter 2012 is provided between the drive unit 203 and the damper 100. The adapter 2012 includes an adapter housing 20121 and an elastic body 20122 disposed in the adapter housing 20121. The elastic body 20122 is provided with a slot 20123 communicating with a through hole. The drive unit 203 has an output housing that accommodates the drive end. The output housing is inserted into the slot 20123. The elastic body 20122 is provided with an abutment protrusion 20124, which abuts against the damper 100.

[0083] In the preferred embodiment of the strut assembly 200 above, the specific configuration and arrangement of the sleeve assembly, drive device and damper 100, etc., can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the sleeve assembly, drive device and damper 100, etc., can also be referred to the descriptions in the above exemplary embodiments.

[0084] The strut assembly 200 of this embodiment adopts the above design. With the setting of the first ball socket 207 and the second ball socket 208, it is convenient to set the shoulder 209 at the opening of the ball joint cavity. The shoulder 209 set on the first ball socket 207 and the second ball socket 208 restricts the axial rotation of the sleeve assembly. It can avoid the lateral friction force generated by the rotation of the anti-rotation limiting structure inside the telescopic mechanism. This can solve the problem of lateral friction force generated inside the telescopic mechanism due to the setting of the anti-rotation limiting structure in the related technology, and thus solve the problem of friction noise caused by the strut assembly 200 during use, which helps to improve the quality of use of the strut assembly 200.
