The electromagnetic assembly 12 is detachably or fixedly connected in the first connecting member 11. When the electromagnetic assembly 12 rotates circumferentially around the first direction X, the first connecting member 11 also rotates circumferentially with the electromagnetic assembly 12.

[0038] The wire harness assembly 16 is used to provide electric current and the like. One end of the wire harness assembly 16 is electrically connected with the electromagnetic assembly 12. The other end of the wire harness assembly 16 is electrically connected with a circuit adjusting structure. The circuit adjusting structure can control the size and direction of the electric current and the like. The circuit adjusting structure can control the size and direction of the electric current in the electromagnetic assembly 12 through the wire harness assembly 16, thereby controlling the speed and direction of the rotational movement in the electromagnetic assembly 12 and the like. The principle of the electromagnetic adjusting structure controlling the electromagnetic assembly 12 through the wire harness assembly 16 can be a conventional principle, which is not limited herein.
[0039] The above electromagnetic assembly 12 and wire harness assembly 16 are arranged between the first connecting member 11 and the second connecting member 13, the linear motion of the second connecting member 13 is converted into the rotary motion of the electromagnetic assembly 12, and the rotary motion of the electromagnetic assembly 12 can be converted into the linear motion of the second connecting member 13. By adjusting the circuit impedance, current size and direction and the like of the electromagnetic motion between the second connecting member 13 and the electromagnetic assembly 12, the relative motion force and speed between the second connecting member 13 and the electromagnetic assembly 12 can be controlled, thereby adjusting the motion damping force value of the suspension damping device 10 to meet the force value response requirements under all working conditions of the vehicle. Compared with the existing passive hydraulic shock absorber, the embodiment has no risk of hydraulic oil leakage, has low maintenance cost, and does not need to be cleaned, is more green and environmentally friendly and the like.
[0040] Please refer to Figure 5 , Figure 5 is a partial explosion schematic diagram of an embodiment of the suspension damping device of the present application. In combination with Figures 1 to 4 In some embodiments, the electromagnetic assembly 12 includes a stator 121 and a rotor 122. The stator 121 is arranged in and connected to the first connecting member 11. The rotor 122 is arranged in the stator 121 and rotates relative to the stator 121. The first connecting member 11 is arranged in and threadedly connected to the rotor 122.
[0041] The stator 121 can be provided with a coil winding, and the working principle between the stator 121 and the rotor 122 is a conventional principle, which will not be described here. The first connecting member 11 provides a mounting position for the stator 121. The stator 121 is arranged in the first connecting member 11. At the same time, the stator 121 is connected to the inner wall of the first connecting member 11. The stator 121 can be detachably or fixedly connected to the first connecting member 11. In the embodiment, the stator 121 is fixedly connected to the first connecting member 11, and the first connecting member 11 moves with the stator 121.
[0042] The stator 121 provides a mounting position for the rotor 122. The rotor 122 is arranged in the stator 121. At the same time, the rotor 122 rotates relative to the stator 121. That is, the rotor 122 rotates relative to the stator 121 in a circumferential direction. The above stator 121 and rotor 122 can be but not limited to a cylindrical shape and the like.
[0043] The rotor 122 provides a mounting position for at least a part of the second connecting member 13. For example, at least a part of the second connecting member 13 is arranged in the rotor 122. When the second connecting member 13 is at least partially arranged in the rotor 122, the second connecting member 13 is threadedly connected to the rotor 122. When the second connecting member 13 moves in the first direction X, the second connecting member 13 threadedly drives the rotor 122 to rotate in a circumferential direction, and then drives the stator 121 and the first connecting member 11 around the outer periphery of the stator 121 to rotate in a circumferential direction.
[0044] Through the cooperation of the stator 121, the rotor 122 and the second connecting piece 13, not only the mutual conversion between the linear motion and the rotary motion is realized, but also the structure is simple and easy to install and operate, and the cost is reduced.
[0045] In some embodiments, the second connecting piece 13 is provided with an outer threaded portion 131 on the outer periphery. The inner wall of the rotor 122 is provided with an inner threaded portion 1221. The outer threaded portion 131 and the inner threaded portion 1221 are threadedly connected.
[0046] The outer threaded portion 131 can be detachably or fixedly connected to the outer periphery of the second connecting piece 13, and the outer threaded portion 131 and the outer periphery of the second connecting piece 13 can be connected. In this embodiment, the outer threaded portion 131 is integrally formed on the outer periphery of the second connecting piece 13. The inner threaded portion 1221 can be detachably or fixedly connected to the inner wall of the rotor 122, and the inner threaded portion 1221 and the inner wall of the rotor 122 can be connected. In this embodiment, the inner threaded portion 1221 is integrally formed on the inner wall of the rotor 122.
[0047] By arranging the outer threaded portion 131 on the second connecting piece 13 and the inner threaded portion 1221 on the inner wall of the rotor 122, not only the mutual conversion between the linear motion and the rotary motion is realized, but also the structure is simple and the cost is low.
[0048] Please refer to Figure 6 and Figure 7 , Figure 6 is a partial structure schematic view of an embodiment of the suspension damping device of the present application; Figure 7 is a structure schematic view of the second connecting piece in the suspension damping device of the present application. In combination with Figures 1 to 5 In some embodiments, the second connecting piece 13 is provided with at least one limiting portion 132 on the outer periphery. The limiting portion 132 can be detachably abutted against the end portion of the rotor 122.
[0049] The limiting portion 132 can play a limiting role. The limiting portion 132 can be, but is not limited to, a limiting block (not shown in the figure) or a limiting ring (not shown in the figure). A plurality of limiting blocks are arranged in a ring shape on the outer periphery of the second connecting piece 13. Alternatively, a limiting ring is arranged in a ring shape on the outer periphery of the second connecting piece 13. In this embodiment, the number of limiting portions 132 is two. The limiting portion 132 is a limiting ring.
[0050] The limiting portion 132 is detachably or fixedly connected to the outer periphery of the second connecting member 13. In this embodiment, the limiting portion 132 is integrally formed on the outer periphery of the second connecting member 13. The limiting portion 132 can be located at the upper part of the outer periphery of the second connecting member 13 or at the lower part of the second connecting member 13. The number of limiting portions 132 can be one, two, three or more, but is not limited to these numbers. When the second connecting member 13 moves in the first direction X, the limiting portion 132 can abut against the end of the rotor 122, or the limiting portion 132 can be disengaged from the end of the rotor 122.
[0051] By limiting the position relationship between the limiting portion 132 and the end of the rotor 122, the movement position of the second connecting member 13 relative to the end of the rotor 122 can be limited, thereby reducing the risk of excessive movement of the second connecting member 13 relative to the rotor 122.
[0052] In some embodiments, two limiting portions 132 are provided on the outer periphery of the second connecting member 13. The external thread portion 131 is located between the two limiting portions 132.
[0053] In some embodiments, two limiting portions 132 are provided on the outer periphery of the second connecting member 13. The external thread portion 131 is located between the two limiting portions 132.
[0054] The upper end of the external thread portion 131 and one end surface of the limiting portion 132 facing the external thread portion 131 are connected. The lower end of the external thread portion 131 and the other end surface of the limiting portion 132 facing the external thread portion 131 are connected.
[0055] By providing the above-mentioned two limiting portions 132 on the second connecting member 13, not only can the up-and-down movement position of the second connecting member 13 relative to the end of the rotor 122 be limited, thereby reducing the risk of excessive movement of the second connecting member 13 relative to the rotor 122, but also the length of the external thread portion 131 in the first direction X can be limited.
[0056] Please refer to Figure 8 and Figure 9 , Figure 8 is a first structure diagram of a rotor in a suspension damping device of the present application; Figure 9 is a second structure diagram of a rotor in a suspension damping device of the present application. In combination with Figures 1 to 7 In some embodiments, the end of the rotor 122 is provided with a first limiting groove 1222. The limiting portion 132 can be disengaged from the first limiting groove 1222.
[0057] The rotor 122 end portion can be, but is not limited to, a rotor 122 top end and a rotor 122 bottom end, and the like. In this embodiment, the rotor 122 top end and the rotor 122 bottom end are both provided with a first limiting groove 1222. The first limiting groove 1222 is provided in a recessed manner. The first limiting groove 1222 can accommodate the limiting portion 132.
[0058] When the second connecting piece 13 moves in the first direction X, the limiting portion 132 can abut against the groove bottom of the first limiting groove 1222, for limiting the limiting portion 132, and further for limiting the movement stroke of the second connecting piece 13, and the like. Alternatively, the limiting portion 132 can be out of abutting relationship with the first limiting groove 1222.
[0059] The number of the first limiting grooves 1222 can correspond to the number of the limiting portions 132. When the number of the first limiting grooves 1222 is one, the number of the limiting portions 132 is one. When the number of the first limiting grooves 1222 is two, the number of the limiting portions 132 is two.
[0060] By providing the first limiting groove 1222 on the rotor 122 end portion, the stability of the limiting portion 132 can be further limited.
[0061] In some embodiments, the suspension damping device 10 further comprises an elastic piece 14. The elastic piece 14 is sleeved on the outer periphery of the outer threaded portion 131. One end of the elastic piece 14 is connected to the end face of the limiting portion 132 close to the outer threaded portion 131.
[0062] The elastic piece 14 has elasticity. The elastic piece 14 can be, but is not limited to, a spring, and the like. The number of the elastic piece 14 can be, but is not limited to, one, two, and the like. The number of the elastic piece 14 can correspond to the number of the limiting portions 132. In this embodiment, the number of the limiting portions 132 and the number of the elastic piece 14 are both two.
[0063] One end of the elastic piece 14 is detachably connected or fixedly connected to the end of the limiting portion 132 close to the outer threaded portion 131. In this embodiment, one end of the elastic piece 14 is fixedly connected to the end face of the limiting portion 132 close to the outer threaded portion 131. When the rotor 122 end portion is provided with the first limiting groove 1222, the elastic piece 14 can move into the first limiting groove 1222.
[0064] By providing the above-mentioned elastic piece 14, the suspension damping device 10 can play a buffering role, and further reduce the direct impact of the limiting portion 132 on the rotor 122 end portion or the groove bottom of the first limiting groove 1222, and the like.
[0065] In some embodiments, the suspension damping device 10 further comprises a bearing piece 15. The outer peripheral surface of the rotor 122 is provided with a second limiting groove 1223. The bearing piece 15 is sleeved on the second limiting groove 1223 and located between the stator 121 and the rotor 122.
[0066] The bearing member 15 can function as a rotating part. The bearing member 15 can be, but is not limited to, a bearing. The bearing is a conventional part and is not limited herein. The second limiting groove 1223 is recessed on the outer circumferential surface of the rotor 122. The second limiting groove 1223 can be used to accommodate at least part of the bearing member 15. The number of the second limiting groove 1223 can be one, two, three or more. The number of the second limiting groove 1223 can be the same as the number of the bearing member 15. In the embodiment, the number of the bearing member 15 and the number of the second limiting groove 1223 are both two.
[0067] By limiting the bearing member 15 in the second limiting groove 1223, the stability of the bearing member 15 installed between the stator 121 and the rotor 122 can be improved. At the same time, the bearing member 15 is arranged between the stator 121 and the rotor 122, realizing the relative rotation of the stator 121 and the rotor 122, thereby reducing the friction between the stator 121 and the rotor 122, etc.
[0068] Please refer to Figure 10 , Figure 10 is a structural schematic diagram of a dust cover in the suspension damping device of the present application. In combination with Figures 1 to 9 In some embodiments, the suspension damping device 10 further comprises a dust cover 17. The dust cover 17 is arranged between the end of the first connecting member 11 away from the peripheral member 20 and the upper support seat.
[0069] The dust cover 17 is detachably or fixedly connected to the end of the first connecting member 11 away from the peripheral member 20 at one end, and is detachably or fixedly connected to the upper support seat at the other end. In the embodiment, the dust cover 17 is detachably connected between the end of the first connecting member 11 away from the peripheral member 20 and the upper support seat.
[0070] Since the second connecting member 13 is at least partially located outside the first connecting member 11, when the dust cover 17 is arranged between the first connecting member 11 and the upper support seat, the dust cover 17 can not only reduce the damage of the second connecting member 13 caused by the flying stones and other debris splashed by the road during movement, but also improve the cleanliness and dustproof requirements of the operation of the suspension damping device 10, and also improve the corrosion resistance, etc. The above-mentioned dust cover 17 can be, but is not limited to, a corrugated dust cover.
[0071] Please refer to Figure 11 and Figure 12 , Figure 11 is a structural schematic diagram of a stator in the suspension damping device of the present application; Figure 12 is a structural schematic diagram of a first connecting member in the suspension damping device of the present application. In combination with Figures 1 to 10In some embodiments, the first connecting piece 11 is provided with a first wire harness hole 111. The stator 121 is provided with a second wire harness hole 1211. The wire harness assembly 16 is sequentially arranged through the first wire harness hole 111 and the second wire harness hole 1211 and connected with the rotor 122.
[0072] The first wire harness hole 111 and the second wire harness hole 1211 provide an installation channel for the wire harness assembly 16. The number of the first wire harness hole 111 and the number of the second wire harness hole 1211 can be one, two, three or more, but are not limited to the above. In the embodiment, the number of the first wire harness hole 111 on the first connecting piece 11 and the number of the second wire harness hole 1211 on the stator 121 are both two.
[0073] The above limitation not only realizes the connection between the circuit adjustment structure and the electromagnetic assembly 12, but also has simple structure and is easy to operate and install.
[0074] The present application provides a vehicle. The vehicle (not shown in the figure) comprises a suspension damping device 10. It should be noted that the suspension damping device 10 in the embodiment is the suspension damping device 10 described in the above embodiment.
[0075] Through the above suspension damping device 10, the vehicle can control the relative movement force and speed between the second connecting piece 13 and the electromagnetic assembly 12 by adjusting the circuit impedance, current size and direction of the electromagnetic movement between the second connecting piece 13 and the electromagnetic assembly 12, thereby adjusting the movement damping force value of the suspension damping device 10 to meet the force value response demand under all working conditions of the vehicle. Compared with the existing passive hydraulic shock absorber, the embodiment has no risk of hydraulic oil leakage, has low maintenance cost, does not need to be cleaned, is more environmentally friendly, etc.
[0076] Please refer to Figure 13 , Figure 13 is a structural schematic view of the peripheral components in the vehicle. In combination with Figures 1 to 12 , the lower end of the first connecting piece 11 in the suspension damping device 10 is connected with the wheels (not shown in the figure) of the vehicle through the peripheral components 20. The above suspension damping device 10 is arranged on the side wall of the front wheel, the rear wheel, the left wheel and the right wheel of the vehicle. The current direction and / or current size in the electromagnetic assembly 12 are adjusted by the circuit adjustment structure to control the compression force and the restoring force of the second connecting piece 13, thereby adjusting the dynamic response of the four wheels of the vehicle and maximizing the matching of the optimal damping force value under all working conditions.
[0077] The ECU (Electronic Control Unit) receives control signals from the vehicle VCU (Vehicle Control Unit), and adjusts the compression and recovery force values of the suspension damping device 10 according to the response requirements of the vehicle in the longitudinal, vertical and lateral directions, so as to match the optimal force values under various working conditions of the vehicle, and realize the optimal performance of the vehicle under all working conditions.

Therefore, the features defined with "first", "second", "third" can explicitly or implicitly include at least one of the features.
