The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0051] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0052] The following describes a center pole 1 , a stator 100 , a linear motor, an electromagnetic vibration absorber 1000 , a suspension system 2000 , and a vehicle 10000 according to an embodiment of the present application with reference to FIG. 1 to FIG. 9 .

[0053] As shown in Figures 1, 3, and 4, the center rod 1 according to an embodiment of the present application has a hollow cavity within. A center rod outlet hole 16 is formed on the peripheral wall 14 of the center rod 1, and the center rod outlet hole 16 communicates with the hollow cavity. The peripheral wall 14 of the center rod 1 also has a magnetic component mounting area 122, which can be used to mount the magnetic component 3. The center rod 1 also has a cooling chamber 142, which can accommodate a cooling medium.

[0054] The hollow cavity can accommodate the electrical connector of the magnetic member 3. The electrical connector can be led to the outside of the rod peripheral wall 14 of the center rod 1 through the center rod outlet hole 16. Of course, the electrical connector can also be led from the outside of the center rod 1 through the center rod outlet hole 16 to the inside of the rod peripheral wall 14 of the center rod 1, which can reduce the risk of the electrical connector being squeezed or damaged. For example, the electrical connector can be a cable 2.

[0055] The center rod 1 can be used for the electromagnetic vibration absorber 1000. By setting a cooling chamber 142 inside the center rod 1, the center rod 1 can be cooled, and then the magnetic part 3 installed on the center rod 1 can be cooled, which is beneficial to the heat dissipation of the entire electromagnetic vibration absorber 1000.

[0056] It should be noted that the center rod 1 has a circumferential wall 14, which includes an inner side and an outer side. This means that there is a gap between the inner and outer sides of the circumferential wall 14, and the gap between the inner and outer sides of the circumferential wall 14 is equal to the thickness of the circumferential wall 14. The hollow cavity and the cooling chamber 142 are both located within the center rod 1. Specifically, the hollow cavity is located within the inner side, and the cooling chamber 142 is located between the inner and outer sides. In other words, the circumferential wall 14 is a solid annular structure with a certain thickness, and the inner side of the circumferential wall 14 encloses the hollow cavity.

[0057] The center rod 1 can be a tapered rod whose cross-sectional area decreases along the axial direction of the center rod 1; or, the center rod 1 can be an expanding rod whose cross-sectional area gradually increases along the axial direction of the center rod 1; or, the center rod 1 can be a stepped rod whose cross-sectional area suddenly changes. The specific type of the center rod 1 is not limited here.

[0058] For example, the center rod outlet hole 16 extends along the radial direction of the center rod 1 , and the cooling chamber 142 is provided in the rod peripheral wall 14 .

[0059] Different from the related art, the present application can eliminate the use of a fixing frame and simplify the structure of the electromagnetic vibration absorber 1000.

[0060] According to the center rod 1 of the embodiment of the present application, the center rod 1 can be applied to the electromagnetic vibration absorber 1000. By providing a magnetic component installation area 122 on the center rod 1, it can be used to fix the magnetic component 3, eliminating the use of the fixing frame, which is beneficial to simplifying the structure of the electromagnetic vibration absorber 1000 and making the whole more compact. By providing a cooling chamber 142 inside the rod peripheral wall 14 of the center rod 1, the center rod 1 can be cooled, and then the magnetic component 3 installed on the center rod 1 can be cooled, which is beneficial to the heat dissipation of the entire electromagnetic vibration absorber 1000.

[0061] For example, the center rod 1 may be applied to the stator 100 of the electromagnetic vibration absorber 1000 .

[0062] As shown in FIG3 and FIG4 , in some embodiments, the cooling chamber 142 is arranged around the axis of the central rod 1 and extends along the circumference of the central rod 1 . The cooling chamber 142 can increase its own cooling range, which is beneficial to improving the heat dissipation effect.

[0063] As shown in Figures 2-4, the center rod 1 is a circular cross-section rod, the center rod 1 has an axis, and the cooling chamber 142 is configured to be arranged around the axis. The cooling chamber 142 extends around the circumference of the center rod 1, which can increase the cooling area and improve the heat dissipation effect.

[0064] As shown in Figures 3 and 4, in some embodiments, the cooling chamber 142 is a multi-layer structure, and the cooling chambers 142 are spaced apart along the radial direction of the central rod 1. By providing the multi-layer structure of the cooling chamber 142 inside the central rod 1, the heat dissipation effect and cooling efficiency can be improved.

[0065] As shown in Figures 1, 3, and 4, in some embodiments, the cooling chamber 142 includes a first cooling chamber 1424, which is located radially inward of the magnetic component mounting area 122. The radial projection of the first cooling chamber 1424 on the center rod 1 at least partially overlaps with the radial projection of the magnetic component mounting area 122 on the center rod 1. The magnetic component 3 can be mounted on the magnetic component mounting area 122, and the magnetic component 3 can be sleeved on the outer surface of the rod peripheral wall 14 of the center rod 1. The first cooling chamber 1424 can partially overlap with the projection of the magnetic component 3 on the axis of the center rod 1. The first cooling chamber 1424 can be arranged opposite the magnetic component 3, shortening the heat transfer path and effectively improving heat dissipation efficiency.

[0066] As shown in Figures 1, 3, and 4, in some embodiments, first cooling chamber 1424 is a closed chamber that is not connected to the outside world. The cooling medium in first cooling chamber 1424 can be converted from gas to liquid to achieve cooling and heat dissipation. For example, first cooling chamber 1424 can absorb heat from magnetic element 3 on center rod 1. As the cooling medium absorbs heat, it converts from liquid to gas, rapidly cooling center rod 1 and magnetic element 3.

[0067] As shown in FIG4 , in some embodiments, the first cooling chamber 1424 includes multiple chamber groups, which are spaced apart along the circumference of the central rod 1. By providing multiple chamber groups and arranging the chamber groups along the circumference of the central rod 1, the cooling range is increased and the heat dissipation effect is improved, and the heat dissipation of the central rod 1 is more uniform.

[0068] As shown in Figures 3 and 4, in some embodiments, there are multiple center rod wire outlet holes 16. On the circumference of the center rod 1, each center rod wire outlet hole 16 is opened between two adjacent chamber groups, so that the cooling medium can escape from the center rod wire outlet hole 16, thereby improving the safety of the electromagnetic vibration absorber 1000.

[0069] As shown in Figures 3 and 4, in some embodiments, each chamber group includes multiple sub-chambers 14241, which are spaced apart along the circumference of the center rod 1. There are N sub-chambers 14241, where N sub-chambers 14241 constitute a chamber group, and N is a positive integer. For example, N can be 1, 2, 3, 4, etc. Providing multiple sub-chambers 14241 can improve the reliability of the structure.

[0070] As shown in Figures 1, 3, and 4, in some embodiments, cooling chamber 142 further includes a second cooling chamber 1423, which extends circumferentially around the axis of central rod 1. First cooling chamber 1424 at least partially surrounds second cooling chamber 1423. That is, in the radial direction of central rod 1, first cooling chamber 1424 and second cooling chamber 1423 are located in different radial directions of central rod 1. The projection of first cooling chamber 1424 on the axis of central rod 1 partially overlaps with the projection of second cooling chamber 1423 on the axis of central rod 1. By providing first cooling chamber 1424 and second cooling chamber 1423, different degrees of cooling can be achieved at different locations on central rod 1, improving heat dissipation efficiency and increasing the heat dissipation capacity and cooling effect of central rod 1.

[0071] As shown in Figures 1, 3 and 4, in some embodiments, in the radial direction of the center rod 1, the minimum distance between the second cooling chamber 1423 and the hollow cavity is smaller than the minimum distance between the first cooling chamber 1424 and the outer peripheral surface of the center rod 1. The first cooling chamber 1424 and the second cooling chamber 1423 are arranged close to the inner part of the center rod 1 in the radial direction, which can reduce the impact on the strength of the circumferential wall 14 of the center rod 1, so that the center rod 1 has sufficient strength to support the magnetic part 3.

[0072] As shown in Figures 1-4, in some embodiments, the center rod 1 includes a first rod segment 11 and a second rod segment 12, the magnetic component mounting area 122 is located on the second rod segment 12, the first cooling chamber 1424 extends from the first rod segment 11 into the second rod segment 12, and the second cooling chamber 1423 is disposed within the first rod segment 11. The first cooling chamber 1424 and the second cooling chamber 1423 are disposed on the first rod segment 11 of the center rod 1, and the first cooling chamber 1424 and the second cooling chamber 1423 are located in different radial directions of the center rod 1 to improve the cooling effect; the first cooling chamber 1424 is disposed on the second rod segment 12 of the center rod 1, and the first cooling chamber 1424 and the second cooling chamber 1423 can cool the magnetic component 3. The first cooling chamber 1424 and the second cooling chamber 1423 are highly coordinated, making full use of the design space of the central rod 1, and the rod peripheral wall 14 is designed to be hollow. At the same time, according to the different functions of the first rod segment 11 and the second rod segment 12 of the central rod 1, spatial separation is utilized to design two different first cooling chambers 1424 and second cooling chambers 1423 for two different cooling schemes, which effectively solves the heat dissipation problem during the operation of the electromagnetic vibration absorber 1000 without adding additional components, and the entire cooling scheme has a compact structure.

[0073] As shown in Figures 1 to 3, in some embodiments, a medium inlet 14211 and a medium outlet 14212 are provided at the end of the first rod segment 11 away from the second rod segment 12. The medium inlet 14211 and the medium outlet 14212 are both connected to the second cooling chamber 1423. The medium inlet 14211 and the medium outlet 14212 can circulate the cooling medium, and the cooling medium of the second cooling chamber 1423 can be circulated and replaced to exchange heat with the outside world, such as air, to improve the heat dissipation effect.

[0074] As shown in Figures 1 and 3, in some embodiments, the hollow cavity includes a wiring cavity 13 located in the first rod segment 11 and a guide cavity 19 located in the second rod segment 12. The diameter of the guide cavity 19 is larger than the diameter of the wiring cavity 13. The sizes of the hollow cavities are different according to the different functions and effects of the hollow cavities, which is conducive to improving the space utilization of the hollow cavities.

[0075] As shown in Figures 1 and 3, the outer surface of the peripheral wall 14 of the center rod 1 is also provided with a sensor mounting area 141, which can be used to mount a sensor. The peripheral wall 14 is a solid annular structure with a certain thickness, and the inner surface of the peripheral wall 14 defines a hollow cavity. This means that a sensor can be mounted on the center rod 1. When the center rod 1 is used in the electromagnetic vibration absorber 1000, its position is fixed, so the sensor does not move. Alternatively, the sensor can be a displacement sensor, a velocity sensor, an acceleration sensor, a temperature sensor, etc.

[0076] For example, the center rod 1 includes a first rod segment 11 and a second rod segment 12, the sensor mounting area 141 is located on the first rod segment 11, the magnetic component mounting area 122 is located on the second rod segment 12, and the hollow cavity includes a wiring cavity 13 located inside the first rod segment 11 and a guide cavity 19 inside the second rod segment 12. The center rod wire outlet through hole 16 is connected to the wiring cavity 13. The guide cavity 19 can be connected to the wiring cavity 13, and the guide cavity 19 and the wiring cavity 13 together form a hollow cavity. Alternatively, in other embodiments, the guide cavity 19 can be separated from the wiring cavity 13 by a partition wall, and the guide cavity 19 and the wiring cavity 13 each form a part of the hollow cavity.

[0077] As shown in Figures 1 to 4, in some embodiments, the center rod 1 further includes a rod ring structure 15, the outer diameter of the rod ring structure 15 being greater than the outer diameter of the second rod segment 12, and the rod ring structure 15 can stop the magnetic component 3 in the axial direction of the center rod 1. The rod ring structure 15 is arranged between the first rod segment 11 and the second rod segment 12. In the axial direction of the center rod 1, the first rod segment 11, the rod ring structure 15 and the second rod segment 12 are arranged in sequence. For example, the magnetic component 3 is installed on the magnetic component installation area 122 of the second rod segment 12, and the rod ring structure 15 is located on the upper side of the magnetic component 3 (as shown in Figure 1). The rod ring structure 15 can limit the axial movement of the magnetic component 3 and prevent the magnetic component 3 from moving to the first rod segment 11.

[0078] As shown in Figures 2 and 3, in some embodiments, the center rod cable outlet through-hole 16 is located on the side of the coil structure 15 facing away from the second rod segment 12. The center rod cable outlet through-hole 16 may be provided only in the first rod segment 11, only in the coil structure 15, or partially in the first rod segment 11 and partially in the coil structure 15. For example, along the axis of the center rod 1, the coil structure 15 has a certain thickness, and each center rod cable outlet through-hole 16 is partially provided in the coil structure 15, but does not completely penetrate the thickness of the coil structure 15. In the radial direction of the center rod 1, the outer diameter of the coil structure 15 is greater than the outer diameter of the second rod segment 12, and the center rod cable outlet through-hole 16 protrudes radially relative to the second rod segment 12. The coil structure 15 can guide and protect electrical connectors, such as signal output cables and other wiring harnesses.

[0079] As shown in Figures 2 and 3, in some embodiments, a second threaded segment 172 is provided at one end of the second rod segment 12 away from the first rod segment 11. The second threaded segment 172 can be threadedly connected to the limiting nut 18, and the magnetic component mounting area 122 is located between the rod ring structure 15 and the second threaded segment 172. The limiting nut 18 can be sleeved on the second threaded segment 172 of the center rod 1. The limiting nut 18 is installed at the lower end of the magnetic component 3, and the rod ring structure 15 is located at the upper end of the magnetic component 3. The limiting nut 18 and the rod ring structure 15 cooperate to limit the axial movement of the magnetic component 3.

[0080] As shown in Figures 1-3, in some embodiments, the end of the first rod segment 11 away from the second rod segment 12 is provided with a first threaded segment 171, and the first threaded segment 171 is used to be threadedly connected to the tower top 700. For example, the stator 100 and the tower top 700 are assembled together via the center rod 1 in the stator 100 and a fastening nut 702. During assembly, the fastening nut 702 is tightened with a torque wrench. To prevent the stator 100 from rotating around the central axis of the center rod 1 along with the fastening nut 702, which would prevent the fastening from becoming impossible, anti-rotation grooves 112 are provided on both sides of the first rod segment 11 on the center rod 1. The housing 601 has positioning holes 6011 corresponding to the anti-rotation grooves 112. During assembly, a long pin is inserted into the pin hole to prevent rotation. The fastening nut 702 is then tightened to complete the assembly.

[0081] In some embodiments, a limited rotation structure 8 is provided on the second rod segment 12. The limited rotation structure 8 is used to limit the rotation of the magnetic member 3 relative to the center rod 1. The magnetic member 3 includes a winding 31 and an iron core 32. The magnetic member 3 is composed of a plurality of windings 31 and iron cores 32, which are stacked on the center rod 1 in a layer of windings 31 and a layer of iron core 32. This design facilitates the manufacture of the iron core 32 and the winding of the windings 31. The iron core 32 is transitionally fitted with the center rod 1, and the limited rotation structure 8 is provided between the iron core 32 and the center rod 1. The limited rotation structure 8 is used to limit the rotation of the iron core 32 about the axis of the center rod 1. For example, the rotation limiting structure 8 includes a rotation limiting pin 823 and a rotation limiting groove 82. The rotation limiting groove 82 includes a first rotation limiting groove 821 arranged on the iron core 32 and a positioning groove 822 on the center rod 1. The first rotation limiting groove 821 on the iron core 32 is a semicircular recess and can be matched with the positioning groove 822 of the semicircular recess on the outer side of the lower part of the center rod 1. During the assembly process, the rotation limiting pin 823 is inserted between the two. This design limits the rotation of the iron core 32 around the central axis of the center rod 1, ensuring that the output line of the winding 31 is consistent with the design state, and thereby improving the stability of the connection between the iron core 32 and the center rod 1. This design ensures that the entire magnetic part 3 is fixed on the center rod 1 according to the design state, which can improve the rigidity of the stator 100 and the stability of the operation of the electromagnetic vibration absorber 1000. For example, the assembly process of the center rod 1 and the iron core 32 can be as follows: first, the rotation-limiting pin 823 is installed in the positioning groove 822 of the center rod 1. The rotation-limiting pin 823 protrudes from the positioning groove 822 along the radial direction of the center rod 1. The rotation-limiting pin 823 and the center rod 1 can be initially fixed with an adhesive material. Then, each layer of the iron core 32 after winding is pressed onto the outside of the center rod 1 in sequence. At this time, the protruding portion of the rotation-limiting pin 823 can play a good guiding role in the assembly of the iron core 32, ensuring the position accuracy of each layer of winding 31. Finally, the press-fitting of all layers of the iron core 32 is completed. The center rod 1 and each layer of the iron core 32 adopt an interference fit to ensure the tightness of the fit. The assembled rotation-limiting pin 823 remains between the center rod 1 and the iron core 32. During operation, since the rotation-limiting pin 823 limits the circumferential rotation of the iron core 32, the unsafe factors caused by the circumferential rotation of the winding 31 are avoided.

[0082] As shown in Figures 2, 3, and 5, sensor mounting area 141, for example, includes at least a sensor positioning plane 1411, on which a sensor fixing structure 1412 is disposed. Sensor positioning plane 1411 allows for more stable sensor placement, improving the stability and reliability of sensor detection operations. Furthermore, sensor fixing structure 1412 secures the sensor to sensor positioning plane 1411, preventing it from falling off and improving the stability and reliability of the connection. If the sensor includes a bracket and a magnet, the bracket can be secured to sensor positioning plane 1411 via sensor fixing structure 1412, and the magnet can be adhered to the bracket.

[0083] Optionally, the sensor fixing structure 1412 may be a screw hole, a rivet hole, etc.

[0084] A sensor positioning structure may also be provided on the sensor positioning plane 1411 to position the sensor in an accurate position before the sensor is fixed. Optionally, the sensor positioning structure may be a positioning hole, a positioning pin, or the like.

[0085] As shown in Figures 1-4 , for example, the center rod 1 has a circular cross-section, the outermost side of the rod peripheral wall 14 is a cylindrical surface, and the sensor positioning plane 1411 is a straight wall surface formed by the outer side of the rod peripheral wall 14 being recessed toward the inner side of the rod peripheral wall 14. Optionally, the sensor positioning plane 1411 is parallel to the axis of the center rod 1.

[0086] As shown in Figures 1-4, in some embodiments, the center rod 1 includes a first rod segment 11 and a second rod segment 12. The sensor mounting area 141 is located on the first rod segment 11, and the second rod segment 12 is provided with a magnetic member mounting area 122. The sensor is mounted on the first rod segment 11 of the center rod 1, and the magnetic member 3 is mounted on the second rod segment 12 of the center rod 1, which can reduce interference between the sensor and the magnetic member 3.

[0087] As shown in Figures 1-4, in some embodiments, the center rod cable outlet hole 16 is located between the sensor mounting area 141 and the magnetic component mounting area 122 in the axial direction of the center rod 1. In conjunction with the above embodiments, the first rod segment 11 and the second rod segment 12 are sequentially arranged along the axial direction of the center rod 1, the sensor mounting area 141 is provided on the first rod segment 11, and the magnetic component mounting area 122 is provided on the second rod segment 12. The sensor is mounted on the sensor mounting area 141, and the magnetic component 3 is mounted on the magnetic component mounting area 122 of the center rod 1. The center rod cable outlet hole 16 is located between the sensor mounting area 141 and the magnetic component mounting area 122. In other words, the sensor and the magnetic component 3 are separated in the axial direction of the center rod 1, and the center rod cable outlet hole 16 is located between the sensor and the magnetic component 3. As a result, the electrical connection wires of the magnetic component 3 can be located close to the center rod cable outlet hole 16, thereby reducing the length of the electrical connection wires and saving costs. If the sensor has a signal transmission line, the sensor's signal transmission line can be located close to the center rod cable outlet hole 16, thereby reducing the length of the signal transmission line and saving costs.

[0088] Optionally, a single-layer cooling structure can be provided between the outer side surface and the inner side surface of the rod peripheral wall 14, that is, in the radial direction of the center rod 1, the interior of the center rod 1 can include multiple cooling chambers 142, and the multiple cooling chambers 142 are dispersedly arranged around the axis of the center rod 1. For example, the multiple cooling chambers 142 can all be located in the same radial direction of the center rod 1.

[0089] As shown in Figures 1 and 7, the stator 100 according to an embodiment of the present application includes a cable 2, a magnetic component 3 and the center rod 1 of the above embodiment. The cable 2 is passed through the center rod wire outlet hole 16, and the cable 2 is partially located in the hollow cavity and partially located outside the center rod 1; the magnetic component 3 is sleeved on the magnetic component installation area 122, and the magnetic component 3 includes a winding wire head, which can be connected to the cable 2.

[0090] As shown in Figures 1 and 7, for example, the stator 100 includes a cable 2, a center rod 1, and a magnetic member 3. The cable 2 is inserted into the center rod outlet hole 16, a portion of the cable 2 is located in the hollow cavity of the center rod 1, and another portion of the cable 2 is located outside the center rod 1. The magnetic member 3 can be sleeved on the magnetic member installation area 122 of the center rod 1, and a portion of the cable 2 is arranged on the outer periphery of the magnetic member 3. The magnetic member 3 includes a winding wire end, which can be led out to the outer periphery of the magnetic member 3, and the winding wire end can be connected to the cable 2. That is, the other portion of the cable 2 can be connected to the winding wire end at the outer periphery of the magnetic member 3. Since the winding wire end is connected to the cable 2 on the outside of the magnetic member 3, the tool operation space is not restricted, and the assembly space is expanded, which is conducive to reducing the difficulty of assembly and improving assembly efficiency. It is also conducive to mass production and easy to intuitively find problems during subsequent maintenance, thereby reducing maintenance costs.

[0091] In the related art, the connection position between the winding wire end of the magnetic component and the cable is located on the inside of the magnetic component. The wire coming out from the inside is not only difficult to thread back and forth for assembly, wastes materials, and occupies design space, but also inconvenient to detect because the connection position is located on the inside of the magnetic component. In the present application, the winding wire end of the magnetic component 3 can be led out to the periphery of the magnetic component 3, and the cable 2 is connected to the periphery of the magnetic component 3, which has a larger assembly space, reduces the difficulty of assembly, and can also improve assembly efficiency, which is conducive to mass production and easy to find problems intuitively during subsequent maintenance. In combination with the above embodiment, the center rod 1 includes a first rod segment 11 and a second rod segment 12. In the axial direction of the center rod 1, the first rod segment 11 is located on one side of the center rod wire outlet through hole 16 (the upper side as shown in Figure 1), and the second rod segment 12 is located on the other side of the center rod wire outlet through hole 16 (the lower side as shown in Figure 1), and the magnetic component 3 can be sleeved outside the second rod segment 12. Specifically, the center rod wire outlet hole 16 and the magnetic part 3 are located at different positions of the center rod 1, so as to avoid interference between the cable 2 and the magnetic part 3 when passing through the center rod wire outlet hole 16, thereby reducing the difficulty of the cable 2 passing through the center rod 1, which is conducive to improving assembly efficiency. In addition, the cable 2 can extend downward after passing through the center rod wire outlet hole 16 to be arranged around the outer periphery of the magnetic part 3, thereby avoiding the waste of wire caused by excessive winding when the cable 2 passes from the inner side of the magnetic part 3 and then winds toward the outer side of the magnetic part 3. Of course, the cable 2 can also be passed from the outer periphery of the magnetic part 3 into the hollow cavity through the center rod wire outlet hole 16. The threading direction at the center rod wire outlet hole 16 is not limited in this application, and the threading direction described is only used to illustrate the structural features.

[0092] Of course, in some optional embodiments, the winding wire ends may also be led out from the inner side or end of the magnetic component 3 to connect to the cable 2 .

[0093] According to the stator 100 of the embodiment of the present application, the above-mentioned center rod 1 is provided. The center rod 1 can be applied to the electromagnetic vibration absorber 1000. By providing a magnetic component installation area 122 on the center rod 1, it can be used to fix the magnetic component 3, eliminating the use of the fixing frame, which is beneficial to simplifying the structure of the electromagnetic vibration absorber 1000 and making the whole more compact. By providing a cooling chamber 142 inside the rod peripheral wall 14 of the center rod 1, the center rod 1 can be cooled, and then the magnetic component 3 installed on the center rod 1 can be cooled, which is beneficial to the heat dissipation of the entire electromagnetic vibration absorber 1000.

[0094] As shown in Figures 1 and 2, in some embodiments, the stator 100 also includes a limiting nut 18, the center rod 1 has a rod ring structure 15, and the limiting nut 18 is threadedly connected to the second threaded segment 172 on the center rod 1. In the axial direction of the center rod 1, one end of the magnetic component 3 abuts against the rod ring structure 15, and the other end of the magnetic component 3 abuts against the limiting nut 18, thereby preventing the magnetic component 3 from sliding along the axial direction of the center rod 1, thereby improving the reliability of the stator 100.

[0095] For example, the stator 100 also includes a wire outlet device 4, which is arranged in the wiring cavity 13. The wire outlet device 4 can fix the cable 2. By setting the wire outlet device 4, the movement of the cable 2 can be constrained, reducing the shaking of the cable 2 in the wiring cavity 13. The wire outlet device 4 can also protect the cable 2, reducing the risk of the cable 2 being squeezed and scratched. The cable 2 includes a phase line portion 23 and a wiring portion 22. The phase line portion 23 is located in the wiring cavity 13 and part of the phase line portion 23 can pass through the center rod wire outlet through hole 16. The wiring portion 22 is arranged on the periphery of the magnetic part 3. The wiring portion 22 is connected to the phase line portion 23. Therefore, the phase line portion 23 can be connected to the wiring portion 22 on the periphery of the magnetic part 3, thereby improving the efficiency and convenience of assembly.

[0096] As shown in Figure 7, the cable 2 includes a phase line portion 23 and a wiring portion 22, and the phase line portion 23 and the wiring portion 22 are connected to each other. The phase line portion 23 is located in the wiring cavity 13 and part of the phase line portion 23 can pass through the center rod outlet hole 16. The winding 31 has multiple winding wire ends of the same phase, and multiple winding wire ends of the same phase are connected in series through the wiring portion 22. That is to say, the wiring portion 22 is connected in series with the winding wire ends of the same phase, and the wiring portion 22 is connected to the phase line portion 23, thereby realizing the electrical connection between the cable 2 and the magnetic part 3. For example, the series connection of multiple winding wire ends of the same phase through the wiring portion 22 and the connection between the phase line portion 23 and the wiring portion 22 can be carried out independently, which is conducive to improving assembly efficiency and achieving mass production.

[0097] As shown in FIG7 , the outlet device 4 has a cable channel 41. The cable channel 41 can fix the phase line portion 23, and the outlet of the cable channel 41 can be aligned with the corresponding center pole outlet hole 16. By providing the cable channel 41 on the outlet device 4, the outlet direction of the phase line portion 23 can be guided and the movement of the phase line portion 23 can be constrained. The outlet device 4 can extend along the axial direction of the center pole 1, and the maximum outer diameter of the outlet device 4 is smaller than the minimum inner diameter of the center pole 1, so that the outlet device 4 can be accommodated in the wiring cavity 13. The phase line portion 23 can be partially arranged inside the outlet device 4. The outlet device 4 is configured in the wiring cavity 13 of the center pole 1, and the cable channel 41 passes through the outlet device 4 along the axial direction of the outlet device 4 (the up and down direction as shown in FIG1 ). As shown in FIG7 , the cable channel 41 includes a wire hole entrance and a wire hole exit. The wire hole exit here is the exit of the cable channel 41, and the wire hole exit is aligned with the corresponding center pole outlet hole 16. The wire hole entrance and the wire hole exit are located at the two ends of the cable channel 41 in the axial direction. The wire hole entrance is close to the upper end of the first rod segment 11, and the wire hole exit is close to the upper end of the second rod segment 12. The phase line portion 23 enters the cable channel 41 from the wire hole entrance, and the phase line portion 23 passes through the cable channel 41 from the wire hole exit. Then, the phase line portion 23 passes through the center rod outlet through hole 16 corresponding to the outlet of the cable channel 41.

[0098] For example, the interior of the wire outlet device 4 is a whole cavity structure, and the wire threading hole inlet and the wire threading hole outlet are both connected to the cavity structure inside the wire outlet device 4 .

[0099] In some embodiments, there are multiple windings 31 of the same phase, and the wiring part 22 is divided into multiple sections. The winding wire ends of adjacent and same-phase windings 31 are connected in series through the corresponding wiring parts 22. The connection assembly between the winding wire ends and the wiring parts 22 can be disassembled, which is conducive to improving assembly efficiency and achieving mass production.

[0100] For example, when winding 31 is a three-phase winding, winding 31 includes a U-phase winding, a V-phase winding, and a W-phase winding. The following uses multiple U-phase windings, such as a first U-phase winding, a second U-phase winding, and a third U-phase winding, as examples to illustrate a connection structure in which multiple same-phase winding ends are connected in series via wiring portion 22.

[0101] The U-phase winding is wound by the U-phase winding, and the U-phase winding is installed in the winding groove. The winding ends of the U-phase winding are U-phase one end and U-phase two end respectively. The U-phase one end is the starting end of the U-phase winding, and the U-phase two end is the end of the U-phase winding, wherein the U-phase one end and the U-phase two end are both led to the outside of the magnetic part 3, and the U-phase two ends of the first U-phase winding can be connected to the U-phase one end of the second U-phase winding through the wiring part 22, and the U-phase two ends of the second U-phase set can be connected to the U-phase one end of the third U-phase winding through the wiring part 22, and the U-phase two ends of the third U-phase winding can be connected to the U-phase one end of the fourth U-phase winding through the wiring part 22. If the U-phase winding includes N, where N is a positive integer, then after multiple winding ends of the same phase are connected in series through the wiring part 22, only the U-phase one end of the first U-phase winding and the U-phase two ends of the Nth U-phase winding are left unconnected. According to the above embodiment, the U-phase ends of the N-th U-phase winding can be connected to the phase line portion 23 via the wiring portion 22. The V-phase winding and the W-phase winding are similar and will not be described in detail here.

[0102] As shown in FIG5 , in some embodiments, a plurality of wire outlet slots 322 are provided on the outer circumference of the core 32 , and the plurality of wire outlet slots 322 are spaced apart along the circumference of the core 32 . At least a portion of the wiring portion 22 can be embedded in the wire outlet slots 322 . That is, the winding wire ends can be led out to the outer circumference of the magnetic member 3 , and the winding wire ends can be connected to the wiring portion 22 in the corresponding wire outlet slots 322 on the outer circumference of the magnetic member 3 . The tool operation space is not restricted, and the assembly space is expanded, which helps to reduce the difficulty of assembly and improve assembly efficiency. It is also conducive to mass production and easy to visually find problems during subsequent maintenance, thereby reducing maintenance costs. The bottom end of the core 32 is provided with a plurality of reinforcing ribs 321 , and the plurality of reinforcing ribs 321 are spaced apart to form wire inlet openings 3212 . The wiring portion 22 can be connected to the wiring portion 22 of other phases through the corresponding wire outlet slots 322 and wire inlet openings 3212 . Such a configuration can make the structure more compact.

[0103] For example, the number of outlet slots 322 is a positive integer multiple of the total number of phases of the winding 31. The number of outlet slots 322 is Z, and the total number of phases of the winding 31 is M. If Q = Z / M, then Q is a positive integer. For example, if M = 3, Z can be a multiple of three, such as 3, 6, 9, or 12. This arrangement can make the spatial arrangement of the multi-phase winding 31 symmetrical, and the electric potential and magnetic potential generated by each phase winding 31 should be symmetrical, thereby improving the stability and reliability of the electromagnetic vibration absorber 1000. It can also meet the various outlet arrangement requirements of the winding wire ends of the winding 31.

[0104] As shown in Figures 1 and 5, in some embodiments, the magnetic component 3 includes multiple windings 31 and multiple iron cores 32. The windings 31 and iron cores 32 can be stacked alternately along the axial direction of the center rod 1, that is, an iron core 32 is sandwiched between two adjacent windings 31. The wiring portion 22 extends along the axial direction of the magnetic component 3. The outer end wire ends of the windings 31 are winding wire ends. The wiring portion 22 includes three-phase wiring, and the same-phase windings 31 can be connected through corresponding same-phase wiring portions 22. Specifically, the electromagnetic vibration absorber 1000 is a linear motor, and the mover 600 of the electromagnetic vibration absorber 1000 moves linearly relative to the stator 100 of the electromagnetic vibration absorber 1000. The structure of multiple windings 31 and multiple iron cores 32 can enhance the intensity of the magnetic field generated by the magnetic component 3. The iron core 32 can concentrate and guide the magnetic field, making the magnetic field stronger and more stable, thereby improving the working efficiency of the magnetic component 3.

[0105] For example, the windings 31 and cores 32 are both annular. The magnetic component 3 is composed of multiple windings 31 and cores 32 stacked one layer at a time. The windings 31 and cores 32 are stacked along the axial direction of the center rod 1. After stacking, the magnetic component 3 is sleeved on the center rod 1, ultimately forming a cylindrical shape. The windings 31 are formed by stacking windings from the inside outward, one coil at a time, until the final coil at the outermost end, forming a coiled spring-like spiral structure. The innermost winding ends are radially extended to the outermost layer. There are three or six wire outlet slots 322 evenly distributed on the circumference of each iron core 32. The wire outlet slots 322 can constrain the wire outlet direction. The winding end of each layer of winding 31 is led out from the designated wire outlet slot 322. According to the principle that the three-phase lines must be connected together in the same phase, the same-phase winding 31 can be led out along the wire outlet slots 322 at the same angle, so that the same-phase winding ends can be easily connected from top to bottom from the outside of the magnetic part 3 using the corresponding wiring part 22. It is worth noting that the winding of each layer of winding 31 of the magnetic part 3 is superimposed from the inside to the outside until the last circle on the outermost side, and the winding wire end at the innermost end is also radially led out to the outside of the outermost layer. Therefore, after the winding of each layer of winding 31 of the magnetic part 3 of the present application is completed, the wire is output from the outside of the magnetic part 3, and the winding wire end is also connected to the cable 2 on the outside of the magnetic part 3. This winding 31 output from the outside is not only simple to thread back and forth and assemble, saves materials, but also effectively utilizes the design space. The connection on the outside of the magnetic part 3 has a larger tool operation space, which is conducive to assembly, and the output wire contact is more stable. It is also easy to troubleshoot during later maintenance, reducing maintenance costs.

[0106] The iron core 32 and the winding 31 are arranged alternately along the axial direction of the center rod 1, and the winding wire ends are connected to the wiring part 22 through the wire outlet slot 322 set on the iron core 32. The wire outlet slot 322 is not only convenient for wire outlet, but also can fix the wiring part 22, so as to facilitate the connection of the same-phase winding wire ends of each layer through the wiring part 22. The same-phase winding wire ends are connected through the wiring part 22, and the wiring part 22 is embedded in the wire outlet slot 322. On the one hand, it can fix the wiring part 22 and reduce the shaking of the wiring part 22; on the other hand, the structure is simple, the fixation reliability is high, and it is easy to assemble.

[0107] Optionally, the magnetic part 3 may include an iron core 32 and multiple windings 31. The iron core 32 is provided with multiple winding grooves, the winding grooves can be installed with the windings 31, and the winding grooves can extend radially. Multiple wire outlet slots 322 are provided on the outer peripheral surface of the iron core 32, and the wire outlet slots 322 can extend axially.

[0108] For example, after the U-phase end of the first U-phase winding 31, the V-phase end of the first V-phase winding 31, and the W-phase end of the first W-phase winding 31 are connected to the wiring portions 22 of the corresponding phases, the different wiring portions 22 can be connected after passing through the corresponding outlet slots 322 and inlet ports 3212. The number of inlet ports 3212 is equal to the total number of phases of the winding 31. In the radial direction of the iron core 32, an outlet slot 322 is correspondingly provided on the outside of each inlet port 3212. As a result, the wiring portions 22 connecting the ends of the same-phase windings can pass through the corresponding outlet slots 322 and the inlet ports 3212 provided for the corresponding outlet slots 322. This arrangement can make the structure more compact.

[0109] For example, a plurality of reinforcing ribs 321 define a harness securing groove 3211 that communicates with the wire inlet 3212. A portion of the wiring portion 22 is accommodated within the harness securing groove 3211. The provision of the harness securing groove 3211 constrains the wiring portion 22, preventing it from swinging freely, reducing the probability of damage to the wiring portion 22, and increasing the service life of the wiring portion 22. The cable 2 is a three-phase cable 2, and the cable 2 is located in the wiring cavity 13. Therefore, the cable 2 in the figure represents the phase portion 23.

[0110] As shown in Figures 1 to 4, the center pole wire outlet through holes 16 include three, each center pole wire outlet through hole 16 corresponds to a phase line portion 23, and the outlet of the cable channel 41 is aligned with the center pole wire outlet through hole 16. As shown in Figure 7, there are also three outlets of the cable channel 41 (not fully shown), and the three-phase line portions 23 respectively pass through the outlets of different cable channels 41 and pass through the corresponding center pole wire outlet through holes 16, that is, the three-phase line portions 23 include a U-phase line portion, a V-phase line portion and a W-phase line portion. The U-phase line portion passes through one cable channel 41 and through one center pole wire outlet through hole 16, the V-phase line portion passes through another cable channel 41 and through another center pole wire outlet through hole 16, and the W-phase line portion passes through another cable channel 41 and through another center pole wire outlet through hole 16.

[0111] Optionally, on the magnetic component 3 , the winding ends of the same-phase winding 31 are connected together by the same-phase wiring portion 22 to form a same-phase winding end group, and the different-phase winding end groups are connected at the reinforcing ribs 321 .

[0112] Therefore, the phase line part 23 passes through the inner side of the center pole 1 from the outside, passes through the wire hole outlet of the wire outlet device 4, and then passes through the center pole wire outlet hole 16, and is connected to the wiring part 22 on the outside of the magnetic part 3. The wire outlet is fixed during the whole process, and the wire outlet device 4 plays the role of fixing and protecting the phase line part 23, solving the problem of the risk of extrusion and scratching in the related technology.

[0113] Optionally, the outlet device 4 can adopt a circular pipe structure, the phase line part 23 is fixed in the pipe, and the three-phase phase line parts 23 respectively pass through the top and bottom of the three pipes on the outlet device 4, and the outlets of the three pipes below the outlet device 4 are evenly distributed in the circumferential direction, and the center rod outlet through hole 16 corresponds one by one to the outlets of the three pipes of the outlet device 4.

[0114] Optionally, three threading hole outlets are arranged at equal angles on the wire outlet device 4.

[0115] The center rod outlet hole 16 is set in one-to-one correspondence with the outlet notch 322. Specifically, the center rod outlet hole 16, the outlet notch 322 and the wire hole outlet of the cable channel 41 are set in one-to-one correspondence, so that the position deviation of the cable 2 is small and the connection is reliable.

[0116] For example, the center rod has three wire outlet through holes 16 , three wire outlet slots 322 , and three wire threading hole outlets of the cable channel 41 , and these three correspond to each other one by one.

[0117] As shown in Figure 7, in some embodiments, the end of the cable 2, away from the magnetic member 3, extends outside the center pole 1. The cable 2 is connected to a plug connector 21. Specifically, the plug connector 21 can be connected to a power source to power the magnetic member 3. The plug connector 21 is a quick-change connector that allows for quick connection to a power source, making operation simple and fast.

[0118] As shown in FIG1 , in some embodiments, the stator 100 further includes a limiting pad 5, which is sleeved on the center rod 1. The center rod 1 includes a first rod segment 11, a second rod segment 12, and a rod ring structure 15, with the first rod segment 11 and the second rod segment 12 being separated by the rod ring structure 15. A portion of the center rod wire outlet hole 16 is defined in the first rod segment 11, while another portion is defined in the rod ring structure 15. The limiting pad 5 is a rotatable structural member that can be sleeved on the first rod segment 11. The limiting pad 5 and the center rod wire outlet hole 16 enclose a wiring limiting hole, through which the cable 2 can pass. Specifically, the center rod outlet hole 16 includes a first outlet half hole 111 and a second outlet half hole 152. The first outlet half hole 111 is opened in the first rod section 11, and the second outlet half hole 152 is opened in the rod ring structure 15. The length of the second outlet half hole 152 in the radial direction of the center rod 1 is greater than the length of the first outlet half hole 111 in the radial direction of the center rod 1. The limiting pad 5 has a limiting pad half hole. The limiting pad half hole and the center rod outlet hole 16 enclose a wiring limiting hole, that is, the limiting pad half hole and the second outlet half hole 152 enclose a wiring limiting hole, and the cable 2 can pass through the wiring limiting hole. As a result, the structure of the center rod 1 can be more compact, the wiring limiting hole can protect the cable 2, and the rod ring structure 15 can limit the axial movement of the magnetic component 3 to prevent the magnetic component 3 from moving to the first rod section 11.

[0119] The linear motor according to the embodiment of the present application includes the stator 100 of the above embodiment.

[0120] As shown in FIG1 , an electromagnetic vibration absorber 1000 according to an embodiment of the present application includes a mover 600 and the stator 100 of the above embodiment. The mover 600 has a mover cavity, the stator 100 is arranged in the mover cavity, and the mover 600 can move axially relative to the stator 100.

[0121] Specifically, the electromagnetic shock absorber 1000 includes a linear motor, which combines a traditional hydraulic damping shock absorber and a linear motor to form the electromagnetic shock absorber 1000 of the present application. The traditional hydraulic damping shock absorber is a passive vibration absorber and does not require the design of motor output lines. The overall structure of the electromagnetic shock absorber 1000 is based on the traditional hydraulic damping shock absorber, in which the intermediate damper is replaced by a linear motor. Its purpose is to use the linear motor for active vibration reduction on the basis of passive vibration reduction. According to the excitation transmitted by the road surface, active control is achieved by adjusting the magnetic part 3, thereby effectively attenuating the excitation transmitted to the passenger compartment on the path, and ultimately improving the vehicle's passability, smoothness and comfort. According to the structural composition of the electromagnetic shock absorber 1000, it mainly includes a stator 100, a mover 600 and a tower top 700, in which the stator 100 and the mover 600 form a linear motor, and the winding wire end of the winding 31 is connected to the stator 100 through the cable 2, and the cable 2 passes through the wiring cavity 13 of the center rod 1 to the outside of the motor.

[0122] According to the electromagnetic vibration absorber 1000 of the embodiment of the present application, the integration of multiple functions enables the electromagnetic vibration absorber 1000 to have a larger electromagnetic force design space and an efficient operating environment on the basis of normal operation, thereby improving overall competitiveness. In addition, the center rod 1 can be applied to the electromagnetic vibration absorber 1000. By providing a magnetic component installation area 122 on the center rod 1, it can be used to fix the magnetic component 3, eliminating the use of a fixing frame, which is conducive to simplifying the structure of the electromagnetic vibration absorber 1000 and making the whole more compact. By providing a cooling chamber 142 inside the rod peripheral wall 14 of the center rod 1, the center rod 1 can be cooled, and then the magnetic component 3 installed on the center rod 1 can be cooled, which is conducive to heat dissipation of the entire electromagnetic vibration absorber 1000.

[0123] As shown in Figure 1, the mover 600 includes a housing 601, a mover magnet 602, and a guide post 6032. The mover magnets 602 are evenly distributed on the inner side of the housing 601, providing a fixed magnetic field. The inner side of the mover magnet 602 forms the mover cavity. The mover magnet 602 is sleeved around the outer periphery of the magnetic member 3 and mounted on the inner wall of the housing 601. The mover magnet 602 is located between the housing 601 and the magnetic member 3. The cable 2 is partially located between the mover magnet 602 and the magnetic member 3. Specifically, there is a gap between the mover magnet 602 and the magnetic member 3. The cable 2 passes through the gap and penetrates the wiring limit hole of the first rod segment 11. When the mover magnet 602 performs linear motion axially relative to the magnetic member 3, interference with the cable 2 can be avoided, and the structure of the electromagnetic vibration absorber 1000 is more compact. The guide column 6032 is connected to the shell 601, and the guide column 6032 can also be connected to the lower arm of the vehicle 10000. The hollow cavity includes a guide cavity 19. At least part of the guide column 6032 can extend into the guide cavity 19 and can move axially along the center rod 1, that is, the guide column 6032 plays a guiding role, thereby improving the stability and reliability of the axial movement of the mover 600.

[0124] For example, the mover magnet 602 is composed of several mover magnet units, which are assembled and fixed on the inner side of the shell 601 and evenly distributed along the circumference. The magnetic field force generated by it interacts with the magnetic part 3 assembled and fixed on the center rod 1, and finally realizes the mutual movement between the mover 600 and the stator 100.

[0125] As shown in Figure 1, for example, the mover 600 includes a housing 601 and a fork arm 603. The mover magnet 602 is mounted on the inner wall of the housing 601. The fork arm 603 can be connected to the housing 601. The fork arm 603 is also used to connect to the lower arm of the subframe. Specifically, the fork arm 603 and the lower arm are assembled to the subframe in conjunction with each other. The fork arm 603 and the housing 601 are connected by bolts, together forming a closed operating environment inside the electromagnetic shock absorber 1000. The connection between the electromagnetic shock absorber 1000 and the vehicle 10000 is achieved through the housing 601 and the fork arm 603, and the structural layout is reasonable.

[0126] As shown in Figure 1, one end of the housing 601 is connected to a fork arm 603, which is provided with a guide post 6032. The guide post 6032 is located near the second rod segment 12 of the center rod 1. The other end of the housing 601 forms a housing hole 6012, through which the center rod 1 can pass. When the mover 600 moves, the housing 601 moves accordingly. When the mover 600 is in the first extreme position, the center rod 1 protrudes the most from the housing hole 6012. When the mover 600 is in the second extreme position, the center rod 1 protrudes the least from the housing hole 6012. The intermediate position of the mover 600 is between the first and second extreme positions. In other words, the housing 601 moves relative to the center rod 1 at the housing hole 6012, and the guide post 6032 moves relative to the center rod 1 at the opening of the second rod segment 12. For example, the first sliding bearing 6041 is embedded in the housing hole 6012 of the housing 601. Specifically, the first sliding bearing 6041 is embedded in the frustum of the housing hole 6012. The frustum can be radially staggered with the upper support member 701, thereby increasing the axial space of the electromagnetic vibration absorber 1000.

[0127] As shown in FIG1 , optionally, the fork arm 603 includes a fork arm body 6031, a guide post 6032 connected to the side of the fork arm body 6031 facing the center rod 1, and the mover 600 further includes a buffer pad 605, which is located between the fork arm body 6031 and the center rod 1, and is sleeved on the guide post 6032 and located outside the end of the center rod 1. When the mover 600 moves to the second extreme position, the buffer pad 605 can absorb the collision of the fork arm body 6031 with the center rod 1, and can buffer the impact of the mover 600 on the stator 100 under extreme working conditions, thereby protecting the magnetic component 3 on the stator 100, playing a protective role and reducing noise.

[0128] For example, one end of the second rod segment 12 of the center rod 1 is connected to the first rod segment 11. The other end of the second rod segment 12 has an opening that communicates with the guide cavity 19. The guide post 6032 can pass through the opening and extend into the guide cavity 19. When the mover 600 moves, the mover 600 has a first extreme position, a second extreme position, and an intermediate position. When the mover 600 is in the first extreme position, the guide post 6032 extends the least into the guide cavity 19. When the mover 600 is in the second extreme position, the guide post 6032 extends the most into the guide cavity 19. The intermediate position of the mover 600 is between the first and second extreme positions.

[0129] As shown in Figure 1, in some embodiments, the electromagnetic vibration absorber 1000 also includes a first sliding bearing 6041 and a second sliding bearing 6042, the shell 601 has a shell hole 6012, the center rod 1 passes through the shell hole 6012 to partially extend out of the shell 601, the first sliding bearing 6041 is arranged between the shell hole 6012 and the outer peripheral surface of the center rod 1, and the second sliding bearing 6042 is arranged between the outer peripheral surface of the guide column 6032 and the cavity wall of the hollow cavity. That is to say, the first sliding bearing 6041 is arranged at the plug-in fitting between the shell 601 and the center rod 1, and the second sliding bearing 6042 is arranged at the plug-in fitting between the guide column 6032 and the guide cavity 19, that is, the first sliding bearing 6041 is arranged at the shell hole 6012 of the shell 601, and the second sliding bearing 6042 is arranged at the opening of the second rod segment 12. By arranging the first sliding bearing 6041 and the second sliding bearing 6042, the sliding of the mover 600 can be made smoother, the operation accuracy of the electromagnetic vibration absorber 1000 can be improved, and the noise can be reduced.

[0130] As shown in FIG. 1 , in some embodiments, the mover 600 further includes a buffer pad 605 . The buffer pad 605 is sleeved on the guide post 6032 and is located outside the end of the center rod 1 .

[0131] As shown in Figure 1, in some embodiments, the electromagnetic shock absorber 1000 further includes a tower top 700. A spring 607 is disposed between the tower top 700 and the housing 601. A local protrusion in the housing 601 supports the spring 607 and dissipates heat throughout the housing. The spring 607 can also cushion road impacts. The tower top 700 includes an upper support member 701, which can be connected to the vehicle body. The center rod 1 can pass through the upper support member 701 to allow the cable 2 to pass through the tower top 700, thereby connecting the electromagnetic shock absorber 1000 to the vehicle body 10000 through the upper support member 701. The tower top 700 cooperates with the shell 601 and seals the interior of the shell 601, that is, the interior of the electromagnetic vibration absorber 1000 is in a sealed state, which improves the stability and reliability of operation; a first threaded section 171 is provided on the center rod 1, and the fastening nut 702 is located on the side of the upper support member 701 away from the mover 600, and the fastening nut 702 is screwed to the first threaded section 171. By cooperating with the fastening nut 702 and the first threaded section 171, the stator 100 can be assembled to the tower top 700, which improves the stability and reliability of the connection and is easy to assemble. The center rod 1 has an end shoulder 113, and the upper support member 701 can stop at the end shoulder 113; the fastening nut 702 is located on the side of the upper support member 701 away from the mover 600, and the fastening nut 702 can be screwed to the first threaded section 171 on the center rod 1, and the upper support member 701 is clamped between the fastening nut 702 and the end shoulder 113; the cooler 608 is fixed on the center rod 1, and the cooling chamber 142 inside the center rod 1 can exchange heat with the cooler 608 to realize heat exchange.

[0132] As shown in Figure 1, the tower top 700 can be fixed on the vehicle body, the center rod 1 passes through the middle of the upper support 701, and the cable 2 also passes through the vehicle body to reach the front cabin. By quickly replacing the connector, that is, the plug-in connector 21 cooperates with the electronic control system, thereby connecting to the electronic control system and finally realizing the control of the electromagnetic shock absorber 1000.

[0133] As shown in FIG. 1 , for example, a dust cover 606 is provided at the connection between the central rod 1 and the housing 601 to prevent dust and other impurities from entering the interior of the housing 601 .

[0134] As shown in FIG6 , in some embodiments, a positioning hole 6011 is provided on the housing 601 , and a positioning pin can penetrate the positioning hole 6011 and cooperate with an anti-rotation groove 112 extending axially on the center rod 1 to limit the rotation of the housing 601 relative to the center rod 1 .

[0135] As shown in FIG8 , the suspension system 2000 according to an embodiment of the present application includes the electromagnetic vibration absorber 1000 according to an embodiment of the present application. By providing the above-mentioned electromagnetic vibration absorber 1000, by providing a magnetic component mounting area 122 on the center rod 1, it can be used to fix the magnetic component 3, eliminating the use of a fixing frame, which is conducive to simplifying the structure of the electromagnetic vibration absorber 1000 and making the whole more compact. By providing a cooling chamber 142 inside the rod peripheral wall 14 of the center rod 1, the center rod 1 can be cooled, and then the magnetic component 3 mounted on the center rod 1 can be cooled, which is conducive to heat dissipation of the entire electromagnetic vibration absorber 1000.

[0136] As shown in FIG9 , a vehicle 10000 according to an embodiment of the present application includes the suspension system 2000 according to the above embodiment.

[0137] It should be emphasized that the center rod 1 of the present application is structurally divided into multiple layers from the outer side surface to the inner side surface of the rod peripheral wall 14, and the different layers are cleverly coordinated with the surrounding components, and the center rod 1 integrates multiple functions; the center rod 1 of the present application is fully coordinated with the tower top 700, the winding 31, the iron core 32, and the shell 601, so that in the same axial space, it can not only realize basic functions such as guidance but also meet the external boundary space restrictions such as the tower top 700 and the fork arm 603, thereby avoiding more valuable axial space for the design of the electromagnetic vibration absorber 1000, thereby obtaining better electromagnetic thrust performance. The rod peripheral wall 14 of the center rod 1 is hollow, and a first cooling chamber 1424 and a second cooling chamber 1423 are formed between the outer side and the inner side of the rod peripheral wall 14, wherein the first cooling chamber 1424 is close to the outer side of the rod peripheral wall 14. From the cross-section, the three chamber groups are staggered with the three center rod outlet holes 16. Each group is composed of a number of sub-chambers 14241. The sub-chambers 14241 are polygonal in cross-section. The first cooling chamber 1424 is closed relative to the outside of the center rod 11, but the first cooling chamber 1424 is interconnected in the first rod segment 11 and the second rod segment 12 of the center rod 1. The first section 1421 of the electromagnetic absorber 1000 is filled with cooling material, corresponding to one cooling solution; the second cooling chamber 1423 is close to the inner side of the center rod 1, and is only located in the first section 11 of the center rod 1.

There is a medium inlet and a medium outlet 14212 on the center rod 11 respectively. The medium inlet and the medium outlet 14212 of the second cooling chamber 1423 are interconnected, similar to a U-shaped through-pipe. The cooling medium enters from the medium inlet and exits from the medium outlet 14212 respectively, bringing the heat to the outside, corresponding to another cooling solution. The two cooling solutions dissipate heat for different parts of different electromagnetic absorbers 1000 according to different heat dissipation requirements, interact with each other, and ultimately ensure that the electromagnetic absorber 1000 maintains efficient operation. The center rod 1 plays a role in rapid heat conduction and heat dissipation during the entire cooling process.
