[0043] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] In the description of the present utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. 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 utility model, unless otherwise specified, "multiple" means two or more.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] The conductive assembly 100 , the stator assembly 1000 , the linear motor, the suspension system and the vehicle according to the embodiments of the present invention are described below with reference to the accompanying drawings.

[0047] like Figure 1 As shown, the conductive component 100 according to the embodiment of the utility model includes: a plurality of conductive members 12 and an insulating member 11. The plurality of conductive members 12 are arranged at intervals, and the insulating member 11 is wrapped around the outer periphery of the plurality of conductive members 12 to form a columnar structure. The plurality of conductive members 12 include a first conductive head and a second conductive head, and the first conductive head and the second conductive head are staggered in the axial direction of the columnar structure.

[0048] It is understandable that the conductive member 12 is wrapped in the insulating member 11. When the conductive component 100 is used in a motor, the insulating member 11 can separate the conductive member 12 from other conductive structures in the motor. The conductive component 100 is electrically connected to different structures at different axial positions of the conductive component 100 through the first conductive head and the second conductive head of the conductive member 12, so as to realize the function of the conductive component 100 to guide current in the motor.

[0049] The conductive component 100 of the present application can improve the reliability of insulation protection of the conductive component 12 by arranging an insulating component 11 to wrap the conductive component 12, and the insulating component 11 and the conductive component 12 form an overall rigid structure. The position of the conductive component 12 in the conductive component 100 is stable, and the setting position of the conductive component 12 in the motor can also remain stable, that is, the position of the conductive component 12 in the motor can remain stable, which can improve the conductive stability and reliability of the conductive component 12.

[0050] In addition, the insulating member 11 is configured to form a columnar structure so that the shape of the insulating member 11 is easily matched with the shape of the inner core shaft of the motor. Figure 3 In the example, the conductive component 100 and the stator core shaft 200 of the linear motor are both cylindrical structures, so that the insulating member 11 can be partially inserted into the first chamber 210 of the stator core shaft 200 to save space in the motor.

[0051] In the present application, there is no limitation on the way in which the insulating member 11 is wrapped around the outer periphery of the conductive member 12. For example, the insulating member 11 can be constructed as an injection molded part, that is, the insulating member 11 is formed by injection molding around the outer periphery of the conductive member 12. At the same time, there is no limitation on the structure of the conductive member 12. For example, when the insulating member 11 is an injection molded part, the conductive member 12 can be a wire or a metal conductive sheet. Even if the conductive member 12 is a soft structure, after injection molding through the insulating member 11, the insulating member 11 and the conductive member 12 form an integral rigid structure.

[0052] In some embodiments, Figure 1 As shown, the insulating member 11 includes: a body portion 111 and a plurality of pin portions 112. The body portion 111 forms a columnar structure, and the plurality of pin portions 112 are arranged at one end of the body portion 111 along the axial direction, and the pin portions 112 extend along the axial direction of the insulating member 11, and the plurality of pin portions 112 are arranged at intervals around the axis of the insulating member 11, and the pin portions 112 are provided with a conductive opening 113 for exposing the first conductive head or the second conductive head.

[0053] It should be noted that the conductive opening 113 is open to the outside and is arranged opposite to the first conductive head or the second conductive head, and the electrical connector for connecting the first conductive head or the second conductive head extends into the opening 230 and connects with the first conductive head or the second conductive head. The connection method of the electrical connector to the first conductive head and the second conductive head is not limited, for example, welding connection is adopted.

[0054] In the present application, an interference fit or transition fit can be set between the electrical connector and the conductive port 113 to improve the positioning accuracy between the electrical connector and the first conductive head or the second conductive head to avoid electrical connection between the electrical connector and other components, thereby ensuring that the electrical connector can be reliably connected to the first conductive head or the second conductive head.

[0055] In addition, the provision of the pin portion 112 can reduce the volume required for the insulating member 11 to wrap the first conductive head or the second conductive head, and can reduce the size of the insulation, which is beneficial to the overall lightweight design of the conductive component 100.

[0056] In the present application, the shape of the pin portion 112 is not limited.

[0057] Furthermore, the conductive member 12 includes: a conductive body and a conductive pin 121. The conductive body is wrapped in the body portion 111, the conductive pin 121 is wrapped in the pin portion 112, the conductive pin 121 is connected to the conductive body, and the conductive pin 121 forms a first conductive head or a second conductive head.

[0058] Thus, the conductive pin 121 can be connected to the electrical connector to achieve electrical connection between the conductive member 12 and the electrical connector. The conductive member 12 is only exposed outside the insulating member 11 at the conductive pin 121, which can ensure that the insulating member 11 completely wraps the conductive body and ensures the insulation reliability between the conductive member 12 and other structures in the motor.

[0059] exist Figure 2-Figure 4 In the specific example shown, the conductive component 100 is inserted into the first chamber 210 of the stator core shaft 200, and the first chamber 210 is provided with a plurality of insertion cavities 220 on the bottom wall, and the plurality of pin portions 112 correspond one-to-one to the plurality of insertion cavities 220, so that the pin portions 112 are inserted into the insertion cavities 220, which can limit the axial rotation of the conductive component 100, thereby reducing or avoiding the self-rotation of the conductive component 100 around the axis, ensuring the stability of the setting position of the first conductive head and the second conductive head in the motor, that is, ensuring that the electrical conduction between the first conductive head and the second conductive head and other structures remains stable.

[0060] It should be noted that when the pin portion 112 is inserted into the insertion cavity 220 , the outer surface of the pin portion 112 at least abuts against the radial inner wall or the radial outer wall of the insertion groove, thereby ensuring the limiting effect of the insertion cavity 220 on the insulating member 11 .

[0061] In some embodiments, Figure 1 As shown, the outer circumferential surface of the insulating member 11 is provided with a plurality of first ribs 114 and a plurality of second ribs 115, the first ribs 114 extend in the axial direction, and the plurality of first ribs 114 are arranged at intervals around the axis of the insulating member 11. The second ribs 115 extend in the axial direction of the insulating member 11, and the plurality of second ribs 115 are arranged at intervals along the axial direction.

[0062] It can be understood that a columnar structure is formed on the insulating member 11 , and the columnar structure is prone to structural changes under the action of shear force.

[0063] Therefore, by providing the first rib 114 and the second rib 115, the structural strength of the insulating part 11 in the axial and circumferential directions can be increased, and structural changes of the insulating part 11 can be reduced or avoided, that is, the structural stability of the conductive component 100 is improved, thereby ensuring the conductive stability of the conductive component 12 in the conductive component 100.

[0064] Preferably, at least part of the first rib 114 and part of the second rib 115 intersect with each other, which can further improve the structural strength.

[0065] In some specific embodiments, the first rib 114 can also serve as a guide rib for the conductive component 100 to guide the placement of the conductive component 100 in the motor. Figure 2 In the example, the conductive component 100 is inserted into the first cavity 210 of the stator core shaft 200. By setting an axially extending guide groove (not shown in the figure) in the first cavity 210, when the conductive component 100 is inserted into the first cavity 210, the first rib 114 is inserted into the guide groove, which can guide the insertion of the conductive component 100 in the first cavity 210 and limit the setting angle of the conductive component 100 in the first cavity 210.

[0066] In some embodiments, the cylindrical structure of the insulating member 11 is configured as a non-rotating body. Therefore, when the conductive component 100 is inserted into the motor along the axial direction, the rotation of the conductive component 100 around the axis is easily blocked by other structures, thereby reducing or avoiding the rotation of the conductive component 100 around the axis, ensuring that the first conductive head and the second conductive head are stably arranged in the motor, that is, ensuring that the electrical conduction between the first conductive head and the second conductive head and other structures remains stable.

[0067] like Figure 2-4 As shown, the stator assembly 1000 according to the embodiment of the utility model comprises: a stator core shaft 200, a stator winding 300 and the conductive assembly 100 of the above embodiment. A first chamber 210 is provided in the stator core shaft 200, the stator winding 300 is provided on the outer peripheral wall of the stator core shaft 200, at least a part of the conductive assembly 100 is inserted into the first chamber 210, and the first conductive head or the second conductive head is electrically connected to the stator winding 300. Among them, an anti-rotation structure 400 is provided between the conductive assembly 100 and the stator core shaft 200.

[0068] The stator assembly 1000 of the present application, by adopting the conductive assembly 100 of the above-mentioned embodiment and arranging the insulating member 11 to wrap the conductive member 12, can improve the reliability of insulation protection of the conductive member 12, and the insulating member 11 and the conductive member 12 form an integral rigid structure, the position of the conductive member 12 in the conductive assembly 100 is stable, and the setting position of the conductive member 12 in the motor can also remain stable, that is, the position of the conductive member 12 in the motor can remain stable, which can improve the conductive stability and reliability of the conductive member 12.

[0069] In addition, by setting the anti-rotation structure 400, the setting position and angle of the conductive component 100 in the first chamber 210 can be limited, thereby improving the stability of the position of the conductive component 100 in the first chamber 210, that is, the setting position of the first conductive head and the second conductive head in the motor can remain stable, ensuring that the electrical conduction between the first conductive head and the second conductive head and other structures remains stable.

[0070] In some embodiments, Figure 3-Figure 6 As shown, the anti-rotation structure 400 includes: a matching anti-rotation protrusion 410 and an anti-rotation slot 420. One of the anti-rotation protrusion 410 and the anti-rotation slot 420 is arranged on the outer surface of the insulating member 11, and the other of the anti-rotation protrusion 410 and the anti-rotation slot 420 is arranged on the inner circumference of the first chamber 210.

[0071] It can be understood that by cooperating with the anti-rotation latch 410 and the anti-rotation slot 420, that is, the anti-rotation latch 410 is engaged with the anti-rotation slot 420, the insulating component 11 can be fixed relative to the inner circumference of the first chamber 210, thereby reducing or avoiding the relative movement between the outer surface of the insulating component 11 and the first chamber 210, that is, reducing or avoiding the rotation of the conductive component 100 relative to the stator core shaft 200.

[0072] Therefore, by setting the anti-rotation structure 400, the position of the insulating part 11 in the first chamber 210 can be positioned, and the rotation of the conductive component 100 relative to the stator core shaft 200 can be reduced or avoided, thereby maintaining the synchronous movement of the conductive component 100 and the stator core shaft 200, and further maintaining the electrical conduction between the first conductive head and the second conductive head and other structures stable.

[0073] In addition, the anti-rotation structure 400 can also limit the axial position of the insulating component 11 in the first chamber 210 , further improving the position stability of the conductive component 100 in the first chamber 210 .

[0074] It should be noted that the anti-rotation protrusion 410 may be arranged on the outer surface of the insulating member 11, and the anti-rotation groove 420 may be arranged on the inner circumference of the first chamber 210; or the anti-rotation groove 420 may be arranged on the outer surface of the insulating member 11, and the anti-rotation protrusion 410 may be arranged on the inner circumference of the first chamber 210.

[0075] In the present application, there is no limitation on the location of the anti-rotation structure 400 on the insulating member 11. Figure 3-Figure 6In the example, the insulating member 11 is provided with a pin portion 112, the anti-rotation structure 400 is provided on the pin portion 112, the bottom wall of the first chamber 210 is provided with an insertion cavity 220, and the inner wall of the insertion cavity 220 is correspondingly provided with the anti-rotation structure 400. Therefore, when the pin portion 112 is inserted and matched with the insertion cavity 220, the anti-rotation protrusion 410 and the anti-rotation groove 420 can be matched, and the axial position and setting angle of the conductive component 100 in the first chamber 210 are positioned, ensuring that the conductive component 100 can be stably plugged into the first chamber 210, and the synchronous movement of the conductive component 100 and the stator core shaft 200 is maintained, ensuring that the electrical conduction between the conductive component 100 and other structures at the first conductive head and the second conductive head remains stable.

[0076] The anti-rotation structure 400 on the insulating member 11 can be disposed on the radial inner side of the pin portion 112, and the anti-rotation structure 400 of the first chamber 210 is correspondingly disposed on the radial inner side wall of the first chamber 210. The anti-rotation structure 400 on the insulating member 11 can also be disposed on the radial outer side of the pin portion 112, and the anti-rotation structure 400 of the first chamber 210 is correspondingly disposed on the radial outer side wall of the first chamber 210.

[0077] Preferably, when the conductive component 100 is plugged into the first chamber 210, the axis of the conductive component 100 coincides with the axis of the stator core shaft 200, so that when the stator component 1000 rotates, the weight distribution of the stator component 1000 around the axis is more uniform, thereby ensuring the stability of the rotation of the stator component 1000 and improving the service life of the stator component 1000.

[0078] Furthermore, the anti-rotation protrusions 410 include at least two, and the at least two anti-rotation protrusions 410 are spaced apart and distributed along the circumference of the conductive component 100 , and the anti-rotation grooves 420 are disposed in one-to-one correspondence with the anti-rotation protrusions 410 .

[0079] Therefore, the conductive component 100 can be simultaneously limited by the anti-rotation structure 400 at different positions along the circumferential direction, so as to ensure the limiting effect of the anti-rotation structure 400 on the conductive component 100 .

[0080] exist Figure 4 In the example, the insulating member 11 is provided with three pin portions 112, and the three pin portions 112 are arranged at intervals along the circumference of the insulating member 11, and the bottom wall of the first chamber 210 is correspondingly provided with three insertion cavities 220, and the three pin portions 112 correspond to the three insertion cavities 220 one by one, and each pair of the pin portions 112 and the insertion cavities 220 is provided with a corresponding anti-rotation structure 400. Thus, the conductive component 100 and the first chamber 210 are matched with three anti-rotation structures 400 along the circumference.

[0081] Preferably, the three pin portions 112 are arranged at equal intervals along the circumference of the insulating member 11 , which can improve the stability of limiting the conductive component 100 .

[0082] In some embodiments, the pin portion 112 is provided with a conductive opening 113 for exposing the first conductive head or the second conductive head. In this case, the conductive opening 113 can also be reused as an anti-rotation slot 420 .

[0083] In some embodiments, Figure 3-6 As shown, the bottom of the first cavity 210 forms an insertion cavity 220 , a portion of the insulating member 11 is plugged into the insertion cavity 220 , and the first conductive head or the second conductive head is located in the insertion cavity 220 .

[0084] Therefore, by inserting a portion of the insulating part 11 into the insertion cavity 220, the axial rotation of the conductive component 100 can be limited, thereby reducing or avoiding the self-rotation of the conductive component 100 around the axis, ensuring the stability of the setting position of the first conductive head and the second conductive head in the motor, that is, ensuring that the electrical conduction between the first conductive head and the second conductive head and other structures remains stable.

[0085] exist Figure 3-Figure 6 In a specific example, a pin portion 112 is provided at one axial end of the insulating member 11, and the pin portion 112 is inserted into the insertion cavity 220 to limit the rotation of the conductive component 100 around the axial direction.
