[0038] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0039] Reference below Figure 1-Figure 10 The vibration reduction device 100 according to an embodiment of the present application is described. The vibration reduction device 100 is applied to a vehicle to buffer the impact force generated by road surface excitation during the vehicle's driving.

[0040] According to the vibration reduction device 100 of the embodiment of the present application, the vibration reduction device 100 is connected between the vehicle body and the suspension, and the vibration reduction device 100 includes: a first support seat 21, a second support seat 22, a connecting rod assembly 3 and a motor 5.

[0041] Specifically, in the vertical direction, the first support seat 21 and the second support seat 22 are arranged between the vehicle body and the suspension, and the first support seat 21 and the second support seat 22 are respectively connected to the vehicle body and the suspension through the connecting rod assembly 3. In other words, the first support seat 21 is connected between the vehicle body and the suspension through the connecting rod assembly 3, and the second support seat 22 is also connected between the vehicle body and the suspension through the connecting rod assembly 3.

[0042] The connection position between the shock absorbing device 100 and the suspension can be arranged at the suspension swing arm or the steering knuckle.

[0043] The motor 5 is connected between the first support base 21 and the second support base 22 , and the motor 5 can apply a driving force to the first support base 21 and the second support base 22 to move closer to each other or away from each other.

[0044] Furthermore, the first support seat 21 and the second support seat 22 are respectively connected to the vehicle body through the connecting rod assembly 3, and at this time, the first support seat 21, the second support seat 22 and the vehicle body (i.e., the connection between the connecting rod assembly 3 and the vehicle body) are arranged in a triangle; the first support seat 21 and the second support seat 22 are respectively connected to the suspension through the connecting rod assembly 3, and at this time, the first support seat 21, the second support seat 22 and the suspension (i.e., the connection between the connecting rod assembly 3 and the suspension) are arranged in a triangle,

[0045] When the first support seat 21 and the second support seat 22 are driven to move away from each other by the motor 5, the distance between the first support seat 21 and the second support seat 22 increases, and the body and the suspension move toward the side of the motor 5, that is, the distance between the body and the suspension decreases; when the first support seat 21 and the second support seat 22 are driven to move toward each other by the motor 5, the distance between the first support seat 21 and the second support seat 22 increases or decreases, and the body and the suspension move away from the motor 5, that is, the distance between the body and the suspension increases.

[0046] Therefore, by adjusting the distance between the first support seat 21 and the second support seat 22 through the motor 5, the distance between the vehicle body and the suspension can be adjusted to achieve the adjustment of the vehicle body height.

[0047] It can be understood that when the shock absorbing device 100 is applied to a vehicle, the up and down bouncing of the wheel can drive the upper and lower support blocks in the shock absorbing device 100 to move up and down, and the force between the vehicle body and the suspension can be fed back to the motor 5 through the first support seat 21, the second support seat 22 and the connecting rod assembly 3, and the motor 5 applies a force in the opposite direction to form damping, thereby improving the driving reliability and stability of the vehicle.

[0048] Taking the working condition of the vehicle wheel jumping upward as an example, the force exerted on the wheel by the upward jump can be transmitted to the second connecting seat 12 through the suspension (such as: suspension swing arm), and further transmitted to the first support seat 21 and the second support seat 22 through the connecting rod assembly 3. At this time, the first support seat 21 and the second support seat 22 have a movement tendency to move outward (away from each other), and the motor 5 connected between the first support seat 21 and the second support seat 22 can apply a driving force to the first support seat 21 and the second support seat 22 to move closer to each other, so as to prevent the first support seat 21 and the second support seat 22 from moving away from each other. Therefore, the motor 5 can apply a reverse resistance between the first support seat 21 and the second support seat 22 to prevent the relative position between the first support seat 21 and the second support seat 22 from changing, which plays a good buffering role on the impact force and improves the comfort and controllability of the vehicle.

[0049] Among them, in the wheel jump condition and the wheel jump condition, the directions of the forces applied by the shock absorber to the vehicle body and the suspension are opposite. In the wheel jump condition, the motor 5 applies a driving force to the first support seat 21 and the second support seat 22 to move away from each other to prevent the first support seat 21 and the second support seat 22 from approaching each other.

[0050] like Figure 1 As shown, in some embodiments of the present application, the connecting rod assembly 3 includes: a first connecting rod 31 , a second connecting rod 32 , a third connecting rod 33 and a fourth connecting rod 34 .

[0051] Among them, the two ends of the first connecting rod 31 are rotatably connected to the vehicle body and the first support seat 21 respectively; the two ends of the second connecting rod 32 are rotatably connected to the vehicle body and the second support seat 22 respectively; the two ends of the third connecting rod 33 are rotatably connected to the suspension and the first support seat 21 respectively; the two ends of the fourth connecting rod 34 are rotatably connected to the suspension and the second support seat 22 respectively.

[0052] Furthermore, the rotation axes of the first connecting rod 31 , the second connecting rod 32 , the third connecting rod 33 and the fourth connecting rod 34 are arranged parallel to each other, so that the adjustment stability of the vibration reduction device 100 can be improved.

[0053] Reference Figure 1 , one end of the first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34 are rotatably connected to one of the vehicle body and the suspension, and the other ends of the first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34 are rotatably connected to the support seat (one of the first support seat 21 and the second support seat 22), that is, each connecting rod has two rotation axes. The rotation axes of the first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34 are arranged parallel to each other, which means that the eight axes are arranged parallel to each other in pairs.

[0054] in, Figure 1 In the axial perspective of the rotation axis, four connecting rods form a quadrilateral, which can achieve the distance control between the vehicle body and the suspension in the vertical direction.

[0055] like Figure 1 As shown, the connection between the first link 31 and the vehicle body, and the connection between the second link 32 and the vehicle body are spaced apart in the horizontal direction, so that the supporting stability of the first link 31 and the second link 32 on the vehicle body can be improved; the connection between the third link 33 and the suspension, and the connection between the fourth link 34 and the suspension are spaced apart in the horizontal direction, so that the supporting stability of the third link 33 and the fourth link 34 on the suspension can be improved.

[0056] like Figure 1As shown, in some embodiments of the present application, the vibration reduction device 100 further includes a first connection seat 11, the first connection seat 11 is provided with a first connection bushing 41, the first connection bushing 41 is connected to the vehicle body, the first connecting rod 31 and the second connecting rod 32 are rotatably connected to the first connection seat 11 respectively, and the axial direction of the first connecting bushing 41 is arranged parallel to the rotation axis. Among them, the first connection seat 11 is connected to the vehicle body through the first connection bushing 41 to enhance the force effect at the first connection seat 11, so that the force at the first connection seat 11 can be stably transmitted to the first connecting rod 31 and the second connecting rod 32, and prevent the torsional force from being generated at the connection between the first connecting rod 31 and the first connection seat 11 and the connection between the second connecting rod 32 and the first connection seat 11. Among them, the second connection seat 12 can be connected to the suspension swing arm or the steering knuckle.

[0057] It can be understood that the first connecting seat 11 is connected to the vehicle body, and the first connecting rod 31 and the second connecting rod 32 are connected to the vehicle body through the first connecting seat 11, so that after the first connecting rod 31 and the second connecting rod 32 are connected to the first connecting seat 11, they can be installed to the vehicle body through the first connecting seat 11, reducing the difficulty of assembling the first connecting rod 31 and the second connecting rod 32 to the vehicle body.

[0058] like Figure 1 As shown, in some embodiments of the present application, the vibration reduction device 100 further includes a second connection seat 12, the second connection seat 12 is provided with a second connection bushing 42, the second connection bushing 42 is connected to the suspension, and the axial direction of the second connection bushing 42 is arranged parallel to the rotation axis. The second connection seat 12 is connected to the vehicle body through the second connection bushing 42 to enhance the force effect at the second connection seat 12, so that the force at the second connection seat 12 can be stably transmitted to the third connecting rod 33 and the fourth connecting rod 34, thereby preventing the generation of torsional force at the connection between the third connecting rod 33 and the second connection seat 12 and the connection between the fourth connecting rod 34 and the second connection seat 12.

[0059] It can be understood that the second connecting seat 12 is connected to the suspension, and the third link 33 and the fourth link 34 are connected to the suspension through the second connecting seat 12, so that after the third link 33 and the fourth link 34 are connected to the second connecting seat 12, they can be installed to the suspension through the second connecting seat 12, reducing the difficulty of assembling the third link 33 and the fourth link 34 to the suspension.

[0060] like Figure 1 As shown, the first connecting seat 11 and the second connecting seat 12 are spaced apart in the vertical direction, and in the vertical direction, the first supporting seat 21 and the second supporting seat 22 are located between the first connecting seat 11 and the second connecting seat 12, and the first supporting seat 21 and the second supporting seat 22 are connected by a motor 5, and the motor 5 can drive the first supporting seat 21 and the second supporting seat 22 to move closer to or away from each other.

[0061] It should be noted that the connecting rod assembly 3 can be connected to the vehicle body or suspension directly or indirectly. When the first connecting seat 11 and the second connecting seat 12 are provided in the shock absorbing device 100, the connecting rod assembly 3 can be connected to the vehicle body or suspension through the connecting seats (such as the first connecting seat 11 and the second connecting seat 12).

[0062] like Fig.10 As shown, in some embodiments of the present application, the motor 5 includes: a housing 51 , a driving rod 52 and a driving assembly 53 .

[0063] Further integration Figure 1 The shell 51 is connected to the first support seat 21, part of the driving rod 52 is arranged in the shell 51, and the driving rod 52 is connected to the second support seat 22. The driving component 53 is arranged in the shell 51, and the driving component 53 is used to drive the driving rod 52 to extend or retract relative to the shell 51, so that the driving motor can apply a driving force to the first support seat 21 and the second support seat 22 to move away from or approach each other.

[0064] Specifically, when the driving rod 52 extends from the housing 51, the axial length of the motor 5 increases, and the driving rod 52 and the housing 51 apply forces in opposite directions and away from each other to the first support seat 21 and the second support seat 22 respectively; when the driving rod 52 is retracted into the housing 51, the axial length of the motor 5 decreases, and the driving rod 52 and the housing 51 apply forces in opposite directions and close to each other to the first support seat 21 and the second support seat 22 respectively. In this way, the distance between the first support seat 21 and the second support seat 22 can be adjusted, and under the drive of the first support seat 21 and the second support seat 22, the distance between the first connecting seat 11 and the second connecting seat 12 can be adjusted.

[0065] Reference Figure 1 In some embodiments, the driving rod 52 is integrally formed with the second supporting seat 22 .

[0066] like Fig.10 As shown, in some embodiments of the present application, the driving assembly 53 includes: a stator 531 and a mover 532, the stator 531 is arranged in the shell 51, and the stator 531 is fixedly connected to the shell 51, the mover 532 is also arranged in the shell 51, and the mover 532 is fixedly connected to the driving rod 52, and the mover 532 can move in the axial direction relative to the stator 531.

[0067] The extending and retracting direction of the driving rod 52 is the same as the axial direction of the motor 5. When the mover 532 moves in the axial direction relative to the housing 51, the mover 532 can drive the driving rod 52 to move synchronously to achieve the extending and retracting action of the driving rod 52.

[0068] Furthermore, the motor 5 can be connected to current, and under the action of the current, the mover 532 can reciprocate in the axial direction in the straight line space around the stator 531. When the stator 531 applies a force opposite to the movement of the mover 532, a damping force can be formed, and the magnitude of the stroke damping force can be changed by changing the magnitude of the electromagnetic force.

[0069] It can be understood that the above-mentioned "movement mode of the mover 532" refers to: driving the drive rod 52 to move in the axial direction under the action of the first support seat 21 and the second support seat 22. Taking the first support seat 21 and the second support seat 22 moving away from each other as an example, when the first support seat 21 and the second support seat 22 move away from each other, the drive rod 52 extends outward from the shell 51 under the action of the second support seat 22, and the mover 532 moves to one side in the circumferential direction under the action of the drive rod 52, and the stator 531 can apply a force in the opposite direction (the other side in the axial direction) to the mover 532 to prevent the drive rod 52 from extending outward, thereby forming a damping force through the cooperation between the stator 531 and the mover 532 to prevent the vibration reduction device 100 from changing in height.

[0070] like Figure 7 , Figure 8 and Fig. 9 As shown, in some embodiments of the present application, the end of the driving rod 52 is rotatably connected to the second supporting seat 22, so as to share the lateral force applied to the motor 5 at the connecting end of the driving rod 52 and the second connecting seat 12, reduce the lateral force applied to the motor 5, and make the motor 5 be subjected to more force along the axial direction of the mover 532, thereby extending the service life of the motor.

[0071] like Figure 8 and Fig. 9 As shown, in a specific embodiment of the present application, a first ball head 521 is provided at the end of the driving rod 52 , and a first hinged portion 221 is provided at the second supporting seat 22 . The first ball head 521 is hingedly matched with the first hinged portion 221 .

[0072] It can be understood that the ball head structure has a high degree of freedom and can fully share the lateral force exerted on the motor 5, and the connection method between the first ball head 521 and the first hinge part 221 is highly reliable and can ensure the power transmission effect between the drive rod 52 and the second support seat 22.

[0073] The first hinged portion 221 may be configured as a hinged seat, the first ball head 521 may be embedded in the hinged seat, and the first ball head 521 may rotate in the hinged seat.

[0074] like Figure 7 As shown, in another embodiment of the present application, a first connecting bearing 522 is provided at the end of the driving rod 52 , and the first connecting bearing 522 is rotatably connected to the second supporting seat 22 .

[0075] Furthermore, the rotation axis of the first connecting bearing 522 is arranged in parallel with the rotation axis of the connecting rod, so that the lateral force can be shared by the first connecting bearing 522 to reduce the lateral force applied to the motor 5 and increase the service life of the motor 5.

[0076] Among them, the above-mentioned “lateral force” refers to the force in the radial direction of the motor 5; the “rotation axis of the connecting rod” refers to the rotation axis of any connecting rod among the above-mentioned first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34.

[0077] like Figure 7 and Figure 8 As shown, in some embodiments of the present application, the shell 51 is provided with a connecting rod 511, and the connecting rod 511 is rotatably connected to the first support seat 21, so that the lateral force can be shared at the connecting rod 511, reducing the lateral force on the drive motor and extending the service life of the motor 5.

[0078] Reference Figure 7 and Figure 8 One end of the shell 51 is open, and the driving rod 52 extends out of the shell 51 from the open end of the shell 51. The connecting rod 511 is arranged at the other end of the shell 51, and the connecting rod 511 extends along the axial direction of the motor 5. One end of the connecting rod 511 is fixed to the shell 51, and the other end of the connecting rod 511 is rotatably connected to the first support seat 21.

[0079] Reference Figure 7 , a second connecting bearing 513 is provided at the end of the connecting rod 511, the connecting rod 511 is connected to the first support seat 21 through the second connecting bearing 513, and the rotation axis of the second connecting bearing 513 is arranged parallel to the rotation axis of the connecting rod; Figure 8 The end of the connecting rod 511 is provided with a second ball head 512, and the first support seat 21 is provided with a second hinged portion 211, and the second hinged portion 211 is hingedly matched with the second ball head 512. In other words, the connection and matching mode of the connecting rod 511 and the first support seat 21 can be the same as the connection and matching mode of the driving rod 52 and the second support seat 22.

[0080] In some embodiments, the connecting rod 511 and the driving rod 52 are arranged in the same line, so as to improve the force effect of the motor 5 in the axial direction. The connecting rod 511 is arranged integrally with the housing 51.

[0081] according to Figure 3-Figure 7 Describe the forces on the components of the vibration reduction device 100 and the actions of the motor 5 under different working conditions in this application:

[0082] Reference Figure 3 , Figure 3The vibration reduction device 100 is in a compression condition (such as wheel jumping), the first connecting seat 11 and the second connecting seat 12 have a tendency to move toward each other in the vertical direction, and the first connecting seat 11 and the second connecting seat 12 further transmit force through the connecting rod assembly 3, so that the first supporting seat 21 and the second supporting seat 22 have a tendency to move away from each other, and the mover 532 of the motor 5 is subjected to a pulling force along the axial direction toward the outside of the shell 51.

[0083] At this time, the direction of the electromagnetic force applied by the stator 531 in the motor 5 to the mover 532 is opposite to the direction of the pulling force applied to the mover 532, thereby forming a damping force. The magnitude of the damping force can be changed by changing the magnitude of the electromagnetic force.

[0084] Reference Figure 4 , Figure 4 The vibration damping device 100 is in a stretching condition (such as: the wheel jumps down), the first connecting seat 11 and the second connecting seat 12 have a tendency to move away from each other in the vertical direction, and the first connecting seat 11 and the second connecting seat 12 further transmit force through the connecting rod assembly 3, so that the first supporting seat 21 and the second supporting seat 22 have a tendency to move towards each other, and the mover 532 of the motor 5 is pushed toward the inner side of the shell 51 in the axial direction.

[0085] At this time, the direction of the electromagnetic force applied by the stator 531 in the motor 5 to the mover 532 is opposite to the direction of the thrust received by the mover 532, thereby forming a damping force. The magnitude of the damping force can be changed by changing the magnitude of the electromagnetic force.

[0086] Reference Figure 5 , Figure 5 When the vibration reduction device 100 is in a raised working condition (such as lifting the vehicle body), the stator 531 of the motor 5 applies an electromagnetic force inward in the axial direction to the mover 532 to further drive the driving rod 52 to be inserted into the inner side of the housing 51 through the mover 532 .

[0087] At this time, driven by the motor 5, the first support seat 21 and the second support seat 22 approach each other along the axial direction of the motor 5, and the first support seat 21 and the second support seat 22 further drive the first connecting seat 11 and the second connecting seat 12 to move through the connecting rod assembly 3, so as to drive the first connecting seat 11 and the second connecting seat 12 away from each other in the vertical direction, thereby increasing the vertical height of the vibration reduction device 100.

[0088] Reference Figure 6 , Figure 6 When the vibration reduction device 100 is in a lowering condition (eg, lowering the vehicle body), the stator 531 of the motor 5 applies an electromagnetic force in an axial outward direction to the mover 532 , so as to further drive the driving rod 52 to extend outward of the housing 51 through the mover 532 .

[0089] At this time, driven by the motor 5, the first support seat 21 and the second support seat 22 move away from each other along the axial direction of the motor 5, and the first support seat 21 and the second support seat 22 further drive the first connecting seat 11 and the second connecting seat 12 to move through the connecting rod assembly 3, so as to drive the first connecting seat 11 and the second connecting seat 12 to approach each other in the vertical direction, thereby reducing the vertical height of the vibration reduction device 100.

[0090] in, Figure 3 and Figure 4 The working condition in is the adaptive adjustment working condition of the vibration reduction device 100. Based on the force conditions of the first connecting seat 11 and the second connecting seat 12, a corresponding damping force is generated to prevent the distance between the first connecting seat 11 and the second connecting seat 12 from changing significantly. Figure 5 and Figure 6 The working condition in FIG. 1 is an active adjustment working condition of the vibration reduction device 100 , and the driving force is output by the motor 5 to actively adjust the distance between the first connecting seat 11 and the second connecting seat 12 to achieve vehicle height adjustment.

[0091] In the present application, the motor 5 is connected between the vehicle body and the suspension through the first support seat 21, the second support seat 22, the connecting rod assembly 3, and the first connecting seat 11 and the second connecting seat 12, so as to improve the linear force condition, make the motor force more inclined to axial force, reduce the lateral force, and thus increase the service life of the motor 5.

[0092] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the motor 5 is configured as a linear motor, and the linear motor 5 is arranged horizontally, thereby saving the space occupied by the linear motor 5 in the vertical direction.

[0093] The vibration reduction device 100 according to the embodiment of the present application has the following advantages:

[0094] (1) By changing the electromagnetic force of the motor, the damping force of the motor 5 is changed, thereby meeting the vehicle's requirements for suspension damping under various working conditions. At the same time, the damping and length of the motor 5 can be adjusted by electronic control, and the adjustment process is fast and accurate.

[0095] (2) The distance between the first support seat 21 and the second support seat 22 is adjusted by the driving motor 5 to adjust the height of the vibration reduction device 100 in the vertical direction, thereby realizing the adjustment of the vehicle body height, and the control accuracy is high and the response is fast, so that the damping force and direction can be quickly changed.

[0096] The vehicle according to the embodiment of the present application includes the above-mentioned vibration reduction device 100. By setting the vibration reduction device 100, the vehicle body height can be adjusted, and the motor 5 in the vibration reduction device 100 is arranged horizontally, which can save the space occupied by the motor 5 in the vertical direction. At the same time, the vibration reduction device 100 can improve the comfort and controllability of the vehicle during driving by changing the damping force of the motor 5.

[0097] In the present application, a motor control device 20 is provided in the vehicle. The motor control device 20 is electrically connected to the motor 5 (eg, connected via a wire, etc.) and is used to control the movement of the motor 5 .

[0098] It should be noted that in the whole vehicle operating condition, the upward and downward movement of the tire is performed rapidly back and forth, and the direction and magnitude of the electromagnetic force are controlled by the motor control device 20 to adapt to the damping force required by the whole vehicle. The damping force is controlled by current, the control response is rapid, and the magnitude of the electromagnetic force is controlled quickly and accurately.
