DETAILED DESCRIPTION

[0029] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0030] In this disclosure, unless otherwise stated, directional words such as "upper" and "lower" generally refer to the relative "upper" and "lower" in the direction of gravity when the vehicle is in use. Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 In the directions of the drawings shown, "inside" and "outside" refer to the "inside" and "outside" relative to the outline of the corresponding component itself. In addition, the terms "first" and "second" and so on used in this disclosure are intended to distinguish one element from another and do not have sequential or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are used only to explain and illustrate this disclosure and should not be understood as limiting this disclosure.

[0031] Hereinafter, a suspension according to an exemplary embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0032] refer to Figures 1 to 10 As shown, in the first aspect of the present disclosure, a damper is provided, including a driving mechanism 100 and an adjusting member 1, wherein the adjusting member 1 is connected to the output end of the driving mechanism 100, and the adjusting member 1 may include a mating surface 11, which can be used to connect with the swing arm structure 200 of the vehicle, so that the driving mechanism 100 drives the swing arm structure 200 to swing through the adjusting member 1.

[0033] When the vehicle is driving, the damper disclosed in the present invention can provide different damping forces to the swing arm structure 200 according to the road conditions, thereby reducing the vibration amplitude of the vehicle when it is driving on, for example, bumpy roads. For example, the vehicle can be provided with detection devices such as laser radar and wheel speed sensors, which can transmit detection data to the central processing unit. The central processing unit can drive the drive mechanism 100 to drive the adjustment member 1 to move according to the conditions of the road surface and the vehicle. In this way, the adjustment member 1 can drive the swing arm structure 200 to swing up and down. At this time, the spring damper 7 on the vehicle suspension will also extend or compress accordingly, and change the stiffness of the spring, so that the damper disclosed in the present invention and the spring damper 7 can work together to reduce the vibration amplitude of the vehicle, thereby improving the vehicle's handling and stability.

[0034] In addition, the adjusting member 1 is provided with a mating surface 11, and the adjusting member 1 can be connected to the swing arm structure 200 through the mating surface 11, that is, there is surface contact between the two. This simplifies the connection structure between the two. Compared with the multi-link mechanism transmission used in the related art, the damper of the present disclosure and the components on the swing arm structure 200 can be arranged more compactly. This arrangement can also increase the connection area between the adjusting member 1 and the swing arm structure 200 to ensure that the two have good strength and transmission effect after connection. Based on this, the damper of the present disclosure can ensure structural strength and transmission effect while applying different damping forces to the swing arm structure 200 according to road conditions, ensuring the comfort and controllability of the vehicle.

[0035] Among them, the swing arm structure 200 can include an upper swing arm 201 and a lower swing arm 202 that are connected. Since the lower swing arm 202 vibrates more violently during the driving of the vehicle, the adjustment part 1 can be connected to the lower swing arm 202 to improve the transmission efficiency and ensure the comfort and controllability of the vehicle.

[0036] In some possible embodiments, in order to minimize the connection structure between the adjusting member 1 and the swing arm structure 200, make the distance between the components of the two more compact, and reduce the space occupied by the two, the mating surface 11 can be directly connected to the swing arm structure 200; or, in order to further ensure the stability and connection strength of the adjusting member 1 and the swing arm structure 200 after connection, the mating surface 11 can be connected to the swing arm structure 200 through the connecting member 2.

[0037] One end of the connector 2 can be connected to the mating surface 11, and the other end can be used to connect to the swing arm structure 200. The connector 2 and the mating surface 11 and / or the swing arm structure 200 can be connected in a variety of ways. For example, in order to ensure the connection stability between the connector 2 and the two, the connector 2 can be fixedly connected to the mating surface 11 and / or the swing arm structure 200, or the adjusting member 1 and the connector 2 can be mated together in an abutting manner to reduce the number of fasteners used to connect the two, facilitate assembly between the two, and improve transmission efficiency while ensuring connection stability.

[0038] In the embodiments of the present disclosure, Figure 10 As shown, the connecting member 2 may include a mating portion 21 and a fixing portion 22, wherein the mating portion 21 is connected to the mating surface 11, and the fixing portion 22 is used to connect to the swing arm structure 200. For example, to ensure the stability of the connection between the connecting member 2 and the swing arm structure 200, the fixing portion 22 may be fixedly connected to the swing arm structure 200, while to simplify the overall structure of the damper and facilitate transmission between the connecting member 2 and the mating surface 11, the mating portion 21 may be in abutment with the mating surface 11.

[0039] In order to reduce the friction between the connecting member 2 and the mating surface 11 and improve the transmission efficiency between the adjusting member 1 and the connecting member 2, the mating portion 21 can be rotatably abutted against the mating surface 11 to reduce the friction between the two by rotating the mating portion 21 on the mating surface.

[0040] Exemplarily, the mating portion 21 can be configured as a bearing, and the fixing portion 22 can be configured as a pin. The bearing can be a spherical bearing. The spherical bearing has a high load-bearing capacity and rotates relatively smoothly, which can ensure the stability of the transmission between the adjusting member 1 and the connecting member 2, reduce the noise during transmission, and reduce the friction between the two, thereby ensuring transmission efficiency; the fixing portion 22 can be configured as a pin, one end of the pin can be connected to the inner ring of the bearing, and the other end can be fixedly connected to the swing arm structure 200, thereby ensuring the connection stability between the connecting member 2 and the swing arm structure 200, so that when the height of the connecting member 2 changes, it can drive the swing arm structure 200 to swing up and down.

[0041] In an embodiment of the present disclosure, the mating surface 11 may include mating areas at different heights; the driving mechanism 100 drives the adjusting member 1 to rotate so that the mating areas at different heights can sequentially connect with the swing arm structure 200. The heights of the different mating areas can be gradually increased or decreased in sequence. In this way, during the rotation of the adjusting member 1, the mating areas at different heights can be connected to the swing arm structure 200 directly or indirectly, for example, through the connecting member 2, thereby adjusting the swing position of the swing arm structure 200. In other words, the adjusting member 1 can transmit the torque of the driving mechanism 100 to convert the torque generated by the driving mechanism 100 into a damping force acting on the swing arm structure 200.

[0042] The present disclosure exemplarily illustrates how the damper of the present disclosure adjusts the swing arm structure 200 under different road conditions of a vehicle.

[0043] When the driving mechanism 100 drives the adjusting member 1 to rotate clockwise, the adjusting member 1 can drive the swing arm structure 200 to swing downward; when the driving mechanism 100 drives the adjusting member 1 to rotate counterclockwise, the adjusting member 1 can drive the swing arm structure 200 to swing upward, and the adjusting member 1 is connected to the lower swing arm 202 of the swing arm structure 200 through the connecting member 2. For example, before the vehicle drives onto the pothole road, the driving mechanism 100 can drive the adjusting member 1 to rotate clockwise to drive the connecting member 2 and the lower swing arm 202 to swing downward, thereby reducing the supporting force of the vehicle's suspension, so that the vehicle's wheels can sink quickly; when the vehicle enters the pothole road, the driving mechanism 100 can drive the adjusting member 1 to rotate counterclockwise to drive the connecting member 2 and the lower swing arm 202 to swing upward, thereby increasing the supporting force of the vehicle's suspension; finally, after the vehicle leaves the pothole road, the driving mechanism 100 can drive the adjusting member 1 to return to its initial state to suppress the vibration of the vehicle after leaving the pothole road.

[0044] Correspondingly, before the vehicle reaches the raised road surface, the driving mechanism 100 can drive the adjusting member 1 to rotate counterclockwise to drive the connecting member 2 and the lower arm 202 to swing upward, thereby increasing the supporting force of the vehicle's suspension; when the vehicle reaches the raised road surface, the driving mechanism 100 can continue to drive the adjusting member 1 to rotate counterclockwise to further and quickly increase the supporting force of the vehicle's suspension; after the vehicle leaves the raised apex of the raised road surface, the driving mechanism 100 can again drive the adjusting member 1 to rotate clockwise to drive the connecting member 2 and the lower arm 202 to swing downward, thereby suppressing the vibration of the vehicle.

[0045] In one embodiment of the present disclosure, Figures 1 to 5As shown, the driving mechanism 100 can drive the adjusting member 1 to rotate on a horizontal plane. At least one end surface of the adjusting member 1 forms a mating surface 11, and an angle is formed between the mating surface 11 and the horizontal plane. The end surface can be directly connected to the swing arm structure 200, or the end surface can be connected to the swing arm structure 200 through the connector 2. Because there is an angle between the mating surface 11 and the horizontal plane, when the driving mechanism 100 drives the adjusting member 1 to rotate, the angle between the horizontal plane and the area where the mating surface 11 and the connector 2 or the swing arm structure 200 are connected will change. As a result, the mating surface 11 will apply an upward or downward force to the connector 2 or the swing arm structure 200 that it abuts, ultimately changing the swing amplitude of the swing arm structure 200, thereby working together with the spring damper 7 to reduce the vibration amplitude of the vehicle and improve the vehicle's controllability and stability.

[0046] For example, Figure 4 and Figure 5 As shown, the adjusting member 1 can be a disc-shaped structure, and the center of the adjusting member 1 can be connected to the output end of the driving mechanism 100. In the process of the driving mechanism 100 driving the adjusting member 1 to rotate, areas of different heights of the mating surface 11 will abut against the connecting member 2, so that the swing arm structure 200 can swing upward or downward, thereby achieving the effect of applying different damping forces to the swing arm structure 200.

[0047] In addition, in order to ensure the connection stability between the adjusting member 1 and the driving mechanism 100, the adjusting member 1 can be connected to the output end of the driving mechanism 100 through a flat key and can be fixed to the driving mechanism 100 by bolts. In addition, a pressure plate can be provided at the connection between the adjusting member 1 and the driving mechanism 100 to limit the adjusting member 1 and prevent the adjusting member 1 from slipping.

[0048] Among them, such as Figures 1 to 5 As shown, the adjusting member 1 may include a first end surface 12 and a second end surface 13 disposed opposite each other, at least one of which may abut against the swing arm structure 200; alternatively, at least one of the first end surface 12 and the second end surface 13 may abut against the connecting member 2 connected to the swing arm structure 200. The two oppositely disposed end surfaces enable the adjusting member 1 to directly or indirectly drive the swing arm structure 200 to swing upward or downward, thereby enabling the damper of the present disclosure to appropriately adjust the swing arm structure 200 according to road conditions, ensuring stable vehicle travel under various road conditions.

[0049] In addition, if Figures 1 to 3As shown, there can be multiple connecting members 2, with at least two connecting members 2 spaced apart in the height direction to form a guide space 3; at least part of the mating surface 11 is located in the guide space 3, so that the end face of the adjusting member 1 can abut against the connecting member 2. For example, two connectors 2 may be provided, and the two connectors 2 are respectively arranged opposite to each other in the height direction. The upper connector 2 may abut against the first end surface 12, and the lower connector 2 may abut against the second end surface 13. In this way, the driving mechanism 100 drives the adjusting member 1 to rotate, which can change the connection area between the end surface of the adjusting member 1 and the connector 2 located in the guide space 3. If the height of the mating area on the end surface gradually increases with the rotation of the adjusting member 1, the first end surface 12 can provide an upward force to the upper connector 2, so that the adjusting member 1 can drive the swing arm structure 200 to swing upward through the connector 2. If the height of the mating area on the end surface gradually decreases with the rotation of the adjusting member 1, the second end surface 13 can provide a downward force to the lower connector 2, so that the adjusting member 1 can drive the swing arm structure 200 to swing downward through the connector 2. That is, when the adjusting member 1 rotates, the connector 2 will bear a corresponding axial load, thereby allowing the connector 2 to drive the swing arm structure 200 to swing upward or downward, thereby achieving the effect of applying different magnitudes of damping force.

[0050] During this process, the connecting member 2 can also be rotatably abutted against the end face of the adjusting member 1. For example, the mating portion 21 of the connecting member 2 can abut against the end face of the adjusting member 1, and the mating portion 21 can be configured as a bearing. In this way, when the bearing abuts against the end face of the adjusting member 1, the rotating adjusting member 1 can also cause the bearing to rotate, thereby reducing the friction between the end faces of the connecting member 2 and the adjusting member 1 and improving the transmission efficiency.

[0051] In addition, if Figures 1 to 3 As shown, a connecting plate 5 can also be provided between the connecting member 2 and the swing arm structure 200. One side of the connecting plate 5 can be connected to the swing arm structure 200, and the other side can be connected to the fixing portion 22 of the connecting member 2. The provision of the connecting plate 5 can increase the connection area between it and the connecting member 2 and the swing arm structure 200, thereby improving the connection stability between the connecting member 2 and the connecting plate 5, as well as the connection stability between the connecting plate 5 and the swing arm structure 200, thereby ensuring the connection strength and transmission efficiency between the connecting member 2 and the swing arm structure 200.

[0052] In the embodiments of the present disclosure, Figure 1 and Figure 2 As shown, the drive mechanism 100 and the adjusting member 1 can be arranged in sequence along the height direction of the vehicle. This can make the arrangement of the drive mechanism 100 and the adjusting member 1 more compact, save the space occupied by the drive mechanism 100 and the adjusting member 1 in the horizontal direction, and facilitate the arrangement and connection between the various components.

[0053] In another possible embodiment of the present disclosure, Figures 6 to 9 As shown, the drive mechanism 100 can drive the adjusting member 1 to rotate within a plane at an angle to the horizontal, and the circumferential sidewalls of the end surface of the adjusting member 1 form a mating surface 11. The circumferential sidewalls of the end surface of the adjusting member 1 can be directly connected to the swing arm structure 200, or alternatively, the circumferential sidewalls of the end surface of the adjusting member 1 can be connected to the swing arm structure 200 via a connector 2. As the drive mechanism 100 drives the adjusting member 1 to rotate, different areas of the circumferential sidewalls of the adjusting member 1 abut against the swing arm structure 200, pushing the swing arm structure 200 upward or downward, thereby applying different damping forces to the swing arm structure 200 and ensuring the comfort and handling of the vehicle. Furthermore, due to the angle between the adjusting member 1 and the horizontal plane, this arrangement of the adjusting member 1 can reduce the horizontal space occupied by the adjusting member 1 to a certain extent compared to a horizontal arrangement, thereby increasing the flexibility of installing the damper of the present disclosure within the limited space of a vehicle.

[0054] It should be noted that the circumferential side wall of the end surface of the adjusting member 1 may refer to the outer circumferential wall of the adjusting member 1 or the inner circumferential wall of the adjusting member 1 .

[0055] The adjusting member 1 can rotate in a plane perpendicular to the horizontal plane. The circumferential sidewalls of the adjusting member 1 configured in this way can fully contact the connecting member 2 or the swing arm structure 200, thereby ensuring the stability of the adjusting member 1 in applying an upward or downward force to the connecting member 2 or the swing arm structure 200 through the mating surface 11 when rotating.

[0056] In the embodiments of the present disclosure, Figures 6 to 9 As shown, the adjusting member 1 may include a cam structure 4, and at least a portion of the circumferential sidewall of the cam structure 4 forms a mating surface 11, so that the circumferential sidewall of the cam structure 4 can directly abut against the swing arm structure 200; alternatively, the circumferential sidewall of the cam structure 4 can abut against the swing arm structure 200 through the connecting member 2. For example, when the driving mechanism 100 drives the cam structure 4 to rotate, the circumferential sidewall of the cam structure 4 can abut against the connecting member 2 or the swing arm structure 200. Due to the characteristics of the cam structure 4 itself, that is, it has an arc-shaped edge with different inner diameters, it can change the height of the swing arm structure 200 or the connecting member 2, so that the swing arm structure 200 can swing up and down, thereby applying a damping force to the swing arm structure 200 to ensure the stability of the vehicle during driving.

[0057] Among them, such as Figures 6 to 9As shown, the adjusting member 1 may further include a groove-shaped structure 6, the sidewall of which forms a mating surface 11; one end of the connecting member 2 is movably disposed in the groove-shaped structure 6 and abuts against the sidewall of the groove-shaped structure 6. That is, the adjusting member 1 can be connected to the swing arm structure 200 via the connecting member 2, and the connecting member 2 abuts against the inner wall of the groove-shaped structure 6. For example, the mating portion 21 of the connecting member 2 can be inserted into the groove-shaped structure 6, and the fixing portion 22 of the connecting member 2, such as a pin, can be connected to the swing arm structure 200. When the driving mechanism 100 drives the adjusting member 1 to rotate, the mating portion 21 will move in the height direction under the action of the mating surface 11 of the groove-shaped structure 6 and move relative to the groove-shaped structure 6. As a result, the connecting member 2 can drive the swing arm structure 200 to swing up and down, thereby applying a damping force to the swing arm structure 200 to ensure the stability of the vehicle during driving.

[0058] In addition, the cam structure 4 and the groove structure 6 can be integrally formed, thereby facilitating the forming and assembly of the cam structure 4 .

[0059] In addition, the mating portion 21 of the connecting member 2 can also be rotatably abutted against the side wall of the groove structure 6. In this way, while the mating portion 21 moves in the groove structure 6, the mating portion 21, such as a bearing, can also rotate synchronously to reduce the friction between the connecting member 2 and the groove structure 6 and improve the transmission efficiency.

[0060] In addition, if Figure 6 and Figure 7 As shown, the drive mechanism 100 can be arranged on one side of the adjusting member 1 in the horizontal direction, and the output end of the drive mechanism 100 extends toward the swing arm structure 200 and is connected to the adjusting member 1. This arrangement can reduce the space occupied by the damper of the present disclosure in the height direction of the vehicle, thereby facilitating the installation of other structural components around the vehicle suspension.

[0061] In the embodiments of the present disclosure, Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 as well as Figure 9 As shown, the drive mechanism 100 may include a drive motor 101, which is connected to the vehicle frame and the output end of the drive motor 101 is suitable for being directly or indirectly connected to the adjusting member 1, and the output shaft of the drive motor 101 can be directly connected to the center of the adjusting member 1, that is, the present disclosure can convert the torque output by the drive motor 101 into a damping force on the swing arm structure 200, thereby improving the stability and controllability of the vehicle during driving while ensuring the stability of the adjusting member 1 during rotation.

[0062] In addition, the drive motor 101 can be configured such that the adjustment member 1 can drive the drive motor 101 to rotate forward or reverse. For example, when a vehicle is traveling on an uneven road, the rough surface causes the swing arm structure 200 to swing up and down. This movement can change the height of the connecting member 2, thereby causing the adjustment member 1 to rotate, which in turn drives the rotor of the drive motor 101 to rotate. After the motor rotor rotates, it cuts the magnetic flux lines to generate an induced current, thereby recovering the energy generated by the vehicle's height vibration and achieving an energy feedback effect.

[0063] In addition, since the vibration of the lower swing arm 202 is relatively severe, the connecting member 2 can be connected to the lower swing arm 202 to improve the energy recovery efficiency.

[0064] In addition, the drive mechanism 100 may further include a reducer 102, the output end of the drive motor 101 is connected to the reducer 102, and the output end of the reducer 102 is connected to the adjusting member 1. The setting of the reducer 102 can reduce the output speed of the drive motor 101 and increase the torque, thereby ensuring the transmission effect of the drive mechanism 100; correspondingly, under the energy feeding condition, the setting of the reducer 102 can also increase the number of rotations of the rotor of the drive motor 101 to improve the energy recovery efficiency. Among them, in addition, the reducer 102 can adopt a planetary gear reducer, a harmonic reducer, an RV reducer or the like reducer 102, and the reducer 102 can be connected to the drive motor 101 by a flat key connection, a spline connection, an optical shaft connection, a coupling connection or the like.

[0065] In the second aspect of the present disclosure, Figure 1 、 Figure 2 、 Figure 6 as well as Figure 7 As shown, a suspension is provided, comprising a swing arm structure 200 and the aforementioned damper. The swing arm structure 200 and the damper are spaced apart, and the damper's adjustment member 1 can be directly or indirectly connected to the swing arm structure 200, so that the driving mechanism 100 drives the swing arm structure 200 to swing through the adjustment member 1. This suspension has all the beneficial effects of the aforementioned damper, which will not be further elaborated in this disclosure.

[0066] In addition, the suspension may further include a spring damper 7, which is disposed on the swing arm structure 200. The damper disclosed herein can actively cause the swing arm structure 200 to swing up and down, thereby working together with the original spring damper 7 on the suspension to reduce the vibration amplitude of the vehicle during driving, thereby improving the vehicle's controllability and stability.

[0067] In addition, the swing arm structure 200 may include an upper swing arm 201 and a lower swing arm 202 connected to the upper swing arm 201; one end of the spring damper 7 is connected to the lower swing arm 202, and the other end is connected to the frame; and / or, the damper adjustment member 1 is directly or indirectly connected to the lower swing arm 202.

[0068] A third aspect of the present disclosure provides a vehicle including the above-mentioned suspension. The vehicle includes all the beneficial effects of the above-mentioned suspension, which will not be further elaborated in the present disclosure.

[0069] In summary, the present disclosure exemplarily illustrates the working process of the damper.

[0070] During vehicle travel, the drive motor 101 and reducer 102 can drive the adjusting member 1 to rotate at different angles based on road conditions, thereby changing the height of the mating surface 11 of the adjusting member 1, thereby adjusting the height of the connecting member 2 that abuts against the mating surface 11. This allows the connecting member 2 to apply a damping force to the swing arm structure 200 connected thereto, causing the swing arm structure 200 to swing up and down, thereby working together with the spring damper 7 to reduce the vibration amplitude of the vehicle. Furthermore, the ability of the connecting member 2 to transmit power by abutting against the mating surface 11 of the adjusting member 1 allows for a more compact arrangement of the various components, while maintaining excellent strength and transmission efficiency.

[0071] For example, before the vehicle drives onto the pothole road, the drive motor 101 and the reducer 102 can first rotate forward to make the swing arm structure 200 swing downward, and after the vehicle enters the pothole road, the drive motor 101 and the reducer 102 can rotate reversely to make the swing arm structure 200 swing upward, and finally after the vehicle leaves the pothole road, the drive motor 101 and the reducer 102 restore the swing arm structure 200 to its initial state.

[0072] Before the vehicle reaches a raised road surface, the drive motor 101 and the reducer 102 may first rotate in the opposite direction to cause the swing arm structure 200 to swing upward, thereby increasing the supporting force of the suspension in the vehicle; when the vehicle reaches a raised road surface, the swing arm structure 200 continues to swing upward, thereby further and quickly increasing the supporting force of the suspension in the vehicle; after the vehicle leaves the raised apex of the raised road surface, the drive motor 101 and the reducer 102 restore the swing arm structure 200 to its initial state, thereby suppressing the vibration of the vehicle.

[0073] In addition, the swing arm structure 200 swings up and down, and this movement can also change the height of the connecting part 2, so that the adjusting part 1 rotates, and then drives the rotor of the drive motor 101 to rotate. After rotating, the rotor of the drive motor 101 cuts the magnetic lines of force to generate an induced current, thereby recovering the energy generated by the vibration of the vehicle in the height direction and achieving the effect of energy feeding.
