The control mechanism 3.3 can determine the rotation direction and the number of rotation turns of the drive rotor 3.7.1 according to the position information of the drive mechanism 3.7, and control the rotation of the drive rotor 3.7.1 based on this. Further, during the operation of the drive mechanism 3.7, the control mechanism 3.3 can control the clutch to contact the drive mechanism 3.7 according to the driving information of the vehicle, drive the clutch to rotate, so as to drive the transmission assembly to rotate and transmit power to the adjustment execution assembly, so that the adjustment execution assembly moves in the vertical direction to adjust the damping force and / or height corresponding to the suspension. Specifically, the driving information of the vehicle can include information such as road surface conditions (vibration conditions), driving speed, and operating conditions (starting, braking, steering, etc.).

[0046] Optionally, the control mechanism 3.3 can also obtain the attribute information of the vehicle, such as the vehicle load mass information.

Optionally, the control mechanism 3.3 can also receive other sensor signals, CAN signals, and Ethernet signals of the vehicle, etc., so that the driving energy can be controlled from the DC high-voltage or low-voltage electrical energy of the vehicle.

[0047] Optionally, the suspension adjustment mechanism 3 further includes a housing 3.10. One end of the adjustment execution assembly is located outside the housing 3.10, and the other end of the adjustment execution assembly is located inside the housing 3.10. The clutch is connected to the housing 3.10; with the adjustment execution assembly as the axis, the transmission assembly, the clutch, and the drive mechanism 3.7 are symmetrically arranged inside the housing 3.10. Specifically, the adjustment execution assembly passes through the housing 3.10, and a sealing structure 3.12, 3.13 is provided between the adjustment execution assembly and the housing 3.10 to prevent dust and the like from entering the suspension adjustment mechanism 3.

[0049] One end of the damping adjustment actuator assembly 3.1 is connected to the vehicle body 1, the other end of the damping adjustment actuator assembly 3.1 is connected to the first transmission assembly 3.4, and the first transmission assembly 3.4 is connected to the first clutch 3.5; whether the first transmission assembly 3.4 transmits power is controlled based on the contact state between the first clutch 3.5 and the drive mechanism 3.7. The damping adjustment actuator assembly 3.1 is configured to move in the vertical direction based on the driving force provided by the first transmission assembly 3.4 according to the contact between the first clutch 3.5 and the drive mechanism 3.7, so as to adjust the corresponding damping force of the suspension.

[0050] Specifically, the damping adjustment actuator assembly 3.1 includes a damping adjustment ejector rod 3.1.1 and a damping adjustment lead screw 3.1.2. The damping adjustment ejector rod 3.1.1 is connected to the vehicle body 1, the damping adjustment lead screw 3.1.2 is connected to the first transmission assembly 3.4, and the damping adjustment ejector rod 3.1.1 is rotatably connected to the damping adjustment lead screw 3.1.2.

The drive mechanism 3.7 further includes a stator 3.7.2 and an electromagnetic clutch armature. The electromagnetic clutch armature includes a first electromagnetic clutch armature 3.7.3. The first electromagnetic clutch armature 3.7.3 cooperates with the first electromagnetic coil 3.5.2, and the control mechanism 3.3 is electrically connected to the first electromagnetic coil 3.5.2 and the stator 3.7.2 respectively.

[0051] In practical applications, when the drive mechanism 3.7 is started and the first clutch 3.5 is in contact with the drive mechanism 3.7, the first transmission assembly 3.4 is driven to rotate. As a result, the damping adjustment lead screw 3.1.2 drives the damping adjustment ejector rod 3.1.1 to move in the vertical direction, adjusting the corresponding damping force of the suspension and further adjusting the suspension height. When the drive mechanism 3.7 is started and the first clutch 3.5 is not in contact with the drive mechanism 3.7, the first transmission assembly 3.4 does not rotate. Under the control of the control mechanism 3.3, the contact between the first clutch 3.5 and the drive mechanism 3.7 is achieved through the mutual attraction between the first electromagnetic coil 3.5.2 and the electromagnetic clutch armature.

[0052] Optionally, the first transmission assembly 3.4 includes a first planet gear 3.4.1, a first sun gear 3.4.2, and a first planet carrier 3.4.3.

Whether the first planet gear 3.4.1 and the first sun gear 3.4.2 rotate is controlled based on the contact state between the first clutch 3.5 and the drive rotor 3.7.1. The damping adjustment actuator assembly 3.1 is configured to move in the vertical direction based on the driving force provided by the first planet gear 3.4.1 and the first sun gear 3.4.2 according to the contact between the first clutch 3.5 and the drive rotor 3.7.1, so as to adjust the corresponding damping force of the suspension.

[0053] In a specific embodiment, the damping adjustment lead screw 3.1.2 is connected to the first planet carrier 3.4.3. When the drive mechanism 3.7 is started and the first clutch 3.5 is in contact with the drive mechanism 3.7, the first sun gear 3.4.2 and the first planet gear 3.4.1 are driven to rotate, and the rotational motion is transformed into a motion in the vertical direction, so that the first planet carrier 3.4.3 moves in the vertical direction, thereby causing the damping adjustment lead screw 3.1.2 to drive the damping adjustment push rod 3.1.1 to move in the vertical direction, adjusting the corresponding damping force of the suspension, and further adjusting the suspension height.

[0054] Optionally, an elastic member 2 is arranged between the suspension adjustment mechanism 3 and the vehicle body 1. One end of the damping adjustment actuator assembly 3.1 passes through the elastic member 2 and is connected to the vehicle body 1. Specifically, the elastic member may include, but is not limited to, a spring.

[0055] Specifically, one end of the height adjustment actuator assembly 3.11 is connected to the wheel 4, and the other end of the height adjustment actuator assembly 3.11 is connected to the second transmission assembly 3.9. The second transmission assembly 3.9 is connected to the second clutch 3.8. Whether the second transmission assembly 3.9 rotates is controlled based on the contact state between the second clutch 3.8 and the drive mechanism 3.7. The transmission ratio of the second transmission assembly 3.9 is greater than that of the first transmission assembly 3.4. The height adjustment actuator assembly 3.11 is configured to move in the vertical direction based on the driving force provided by the second transmission assembly 3.9 according to the contact between the second clutch 3.8 and the drive mechanism 3.7, so as to adjust the corresponding height of the suspension.

[0056] Optionally, a first clutch 3.5 and a second clutch 3.8 are respectively arranged at both ends of the driving rotor 3.7.1; the second transmission assembly 3.9 includes a second planet gear 3.9.1, a second sun gear 3.9.2 and a second planet carrier 3.9.3. The second clutch 3.8 is connected to the second sun gear 3.9.2, the second sun gear 3.9.2 is connected to the second planet gear 3.9.1, the second planet carrier 3.9.3 passes through the second sun gear 3.9.2, and the height adjustment actuator assembly 3.11 is fixedly arranged on the second planet carrier 3.9.3; the contact state between the second clutch 3.8 and the driving rotor 3.7.1 controls whether the second planet gear 3.9.1 and the second sun gear 3.9.2 rotate. The height adjustment actuator assembly 3.11 is used to move in the vertical direction based on the driving force provided by the second planet gear 3.9.1 and the second sun gear 3.9.2 according to the contact between the second clutch 3.8 and the driving rotor 3.7.1 to adjust the corresponding height of the suspension.

[0057] In a specific embodiment, the specific structure of the height adjustment actuator assembly 3.11 can be the same as that of the damping adjustment actuator assembly 3.1, and the specific structure of the second clutch 3.8 can be the same as that of the first clutch 3.5. Specifically, the height adjustment actuator assembly includes a height adjustment jack 3.11.1 and a height adjustment jack lead screw 3.11.2. The height adjustment jack 3.11.1 is connected to the wheel 4, the height adjustment jack lead screw 3.11.2 is connected to the second planet carrier 3.9.3, and the height adjustment jack 3.11.1 is rotatably connected to the height adjustment jack lead screw 3.11.2; the second clutch 3.8 includes a second clutch housing 3.8.1, a second electromagnetic coil 3.8.2, a second clutch rotor 3.8.3 and a second clutch bearing 3.8.4, and the control mechanism 3.3 is electrically connected to the second electromagnetic coil 3.8.2. The electromagnetic clutch armature includes a first electromagnetic clutch armature 3.7.3 and a second electromagnetic clutch armature 3.7.4, and the first electromagnetic clutch armature 3.7.3 cooperates with the first electromagnetic coil 3.5.2.

[0058] In practical applications, when the driving mechanism 3.7 is started and the second clutch 3.8 is in contact with the driving mechanism 3.7, it drives the second sun gear 3.9.2 and the second planet gear 3.9.1 to rotate and transforms the rotational motion into a motion in the vertical direction, causing the second planet carrier 3.9.3 to move in the vertical direction, so that the height adjustment jack lead screw 3.11.2 drives the height adjustment jack 3.11.1 to move in the vertical direction to adjust the suspension height.

[0059] Specifically, the first planet gear 3.4.1 cooperates with a ring gear fixed to the housing 3.10 or the housing 3.10 itself. The same applies to the specific setting of the second planet gear 3.9.1.

[0060] In the embodiments of this specification, during the operation of the drive mechanism 3.7, the control mechanism 3.3 can control the first clutch 3.5 and / or the second clutch 3.8 to contact the drive mechanism 3.7 based on the driving information. That is, according to different vehicle driving information (such as road surface conditions), the damping adjustment execution component 3.1 and / or the height adjustment execution component 3.11 can be adjusted accordingly. For example, since the transmission ratio of the height adjustment execution component 3.11 is greater than that of the damping adjustment execution component 3.1, when the road surface condition is relatively flat and the change of the road surface condition is slow, the second clutch 3.8 can be controlled to contact the drive mechanism 3.7, so that the height adjustment execution component 3.11 slowly adjusts the suspension height; when the road surface condition is relatively bumpy and the change of the road surface condition is fast, the first clutch 3.5 can be controlled to contact the drive mechanism 3.7, so that the damping adjustment execution component 3.1 quickly adjusts the suspension height.

[0061] In the embodiments of this specification, the drive mechanism drives the gear transmission mechanism to be directly connected to the screw piston assembly, and an electromagnetic braking device is equipped inside, which can realize the high-frequency dynamic active force control and the low-frequency height maintenance adjustment through a set of drive mechanisms, cancel the intermediate hydraulic conversion link, improve the response efficiency of the suspension adjustment system, and be more environmentally friendly at the same time.

[0062] In some working conditions, the suspension is excited by the road surface, which will cause the drive mechanism 3.7 to rotate actively, and the control mechanism 3.3 can recover the electric energy generated by the passive rotation of the drive mechanism 3.7.

[0063] Specifically, the above connection methods may include connection methods such as fixed connection and movable connection.

[0064] As can be seen from the technical solutions provided by the embodiments of this specification above, the suspension adjustment mechanism in this specification is applied to the suspension system of a vehicle. The vehicle includes a body and wheels. The suspension adjustment mechanism includes an adjustment execution component, a transmission component, a clutch, and a drive mechanism. The adjustment execution component is respectively connected to the body and the wheels. The adjustment execution component is connected to the transmission component, and the transmission component is connected to the clutch; based on the contact state between the clutch and the drive mechanism, it is controlled whether the transmission component transmits power. The adjustment execution component is used to move in the vertical direction based on the transmission force formed by the contact between the clutch and the drive mechanism of the transmission component, so as to adjust the damping force and height corresponding to the suspension, so that the active force control of the suspension and the vehicle height control can be realized, the response efficiency and adjustment accuracy of the suspension can be improved, and the vehicle chassis performance can be improved.
