Description

[0001] The present invention claims priority to Chinese patent application number 202410385834.2 filed on March 29, 2024, entitled “STATOR ASSEMBLY, LINEAR MOTOR, SUSPENSION SYSTEM AND VEHICLE”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present invention relates to the technical field of vehicles, and in particular to a motor, a suspension system and a vehicle. Background Art

[0003] A motor typically consists of a stator assembly and a rotor assembly. The stator assembly includes a winding assembly, while the rotor assembly includes permanent magnets. The winding assembly needs to be connected to an external motor controller via connecting wires. When power is supplied to the winding assembly via the connecting wires, electromagnetic induction is generated between the winding assembly and the permanent magnets, achieving relative motion between the stator and rotor assemblies.

[0004] In related technologies, the electromagnetic suspension includes a motor, which can be a cylindrical linear motor or a plate linear motor. The motor is connected between the wheel and the body. One of the current difficulties encountered by the motor is the sealing problem of the motor. If the sealing is not good, water can easily enter and cause damage to the motor, or foreign objects can enter and affect the service life of the motor. Summary of the Invention

[0094] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0095] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0096] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0097] The present application provides a vehicle 1000. The vehicle 1000 may be a pure electric vehicle, a hybrid electric vehicle, a plug-in hybrid electric vehicle, an extended-range electric vehicle, a fuel vehicle, etc. The vehicle 1000 may also be a car, a van, a bus, a truck, a trailer, etc.

[0098] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in an embodiment of the present application. Vehicle 1000 includes a body 100 and wheels 200. Body 100 is used for seating passengers and carrying items. Wheels 200 are mounted beneath body 100 to support body 100 and are capable of rolling on the road to enable vehicle 1000 to travel.

[0099] The vehicle 1000 further includes a suspension system 300. The suspension system 300 is provided between the vehicle body 100 and the wheels 200 for transmitting force between the vehicle body 100 and the wheels 200 and for cushioning impact forces applied to the vehicle body 100 during travel, thereby improving riding or driving comfort.

[0100] The suspension system 300 may be a non-independent suspension system, an independent suspension system, or an active suspension system.

[0101] In some embodiments of the present application, the suspension system 300 is an active suspension system, and the stiffness and damping characteristics of the active suspension system can be dynamically adaptively adjusted according to the driving conditions of the vehicle 1000 (such as the motion state of the vehicle 1000 and the condition of the road surface, etc.) so that the suspension system 300 is always in the optimal vibration reduction state.

[0102] For details, please refer to Figure 2 , Figure 2 for Figure 1FIG2 is a perspective view of a suspension system 300 in a vehicle 1000. The suspension system 300 may include a motor 10, a mounting base 20, and a fork arm 30. One of the mounting base 20 and the fork arm 30 is connected to the vehicle body 100, while the other of the mounting base 20 and the fork arm 30 is connected to the wheel 200. Specifically, when the fork arm 30 is connected to the vehicle body 100, the mounting base 20 is connected to the wheel 200; and when the fork arm 30 is connected to the wheel 200, the mounting base 20 is connected to the vehicle body 100.

[0103] See also Figure 3 , Figure 3 for Figure 2 The suspension system 300 shown here is a schematic diagram of the structure without the mounting base 20 and elastic element. The motor 10 includes a stator assembly 1 and a mover assembly 2. The stator assembly 1 and the mover assembly 2 are capable of relative movement along the axial direction of the motor 10. The stator assembly 1 is adapted to be connected to the vehicle body 100, and the mover assembly 2 is adapted to be connected to the wheel 200. The mounting base 20 is connected to the stator assembly 1. The fork arm 30 is connected to the mover assembly 2.

[0104] In this way, by the relative movement of the stator assembly 1 and the mover assembly 2, the relative displacement between the fixing seat 20 and the fork arm 30 can be adjusted, thereby adjusting the distance between the vehicle body 100 and the wheel 200, so that the stability of the vehicle body 100 can be ensured when the vehicle 1000 is driving on a rough road or turning, thereby improving the driving comfort of the vehicle 1000.

[0105] Please continue reading Figure 2 The suspension system 300 further includes a lower support 40 and an elastic element 50. The lower support 40 is connected to the movable subassembly 2. The elastic element 50 is connected between the lower support 40 and the fixing seat 20.

[0106] When the motor 10 adjusts the relative displacement between the fixing seat 20 and the fork arm 30, the elastic element 50 will expand and contract with the relative movement of the fixing seat 20 and the fork arm 30, thereby adjusting the buffering performance of the elastic element 50 so that the buffering performance of the elastic element 50 meets the buffering requirements of the vehicle 1000, thereby further improving the driving comfort of the vehicle 1000.

[0107] In some embodiments, please refer to Figure 3 The moving component 2 includes a housing 21. The housing 21 may be a cylindrical structure. The stator component 1 includes a core shaft 11.

[0108] See also Figure 4 , Figure 4 for Figure 3 The cross-sectional view of the suspension system 300 is shown. The core shaft 11 is partially disposed in the housing 21, and the core shaft 11 and the housing 21 are slidably connected along the axial direction of the core shaft 11. The axial direction of the core shaft 11 is consistent with the axial direction of the motor 10.

[0109] The fixing seat 20 is connected to the core shaft 11. Specifically, the fixing seat 20 is connected to the portion of the core shaft 11 located outside the housing 21. The fixing seat 20 and the core shaft 11 can be connected by welding, clamping, screwing, etc., or by other components, which are not specifically limited here.

[0110] The fork arm 30 is connected to the housing 21. Specifically, the fork arm 30 is connected to the end of the housing 21 facing away from the fixing base 20. The fork arm 30 and the housing 21 can be connected by welding, clamping, screwing, etc., or by other components, which are not specifically limited here.

[0111] The relative sliding of the housing 21 and the core shaft 11 can drive the fixing seat 20 and the fork arm 30 to move relative to each other, thereby adjusting the relative displacement between the fixing seat 20 and the fork arm 30 and further adjusting the distance between the vehicle body 100 and the wheel 200 .

[0112] In some examples, the lower support 40 is connected to the housing 21. The elastic element 50 abuts the lower support 40 and the fixing seat 20, respectively. Specifically, the elastic element 50 is in a compressed state when clamped between the lower support 40 and the fixing seat 20. For example, the elastic element 50 may include multiple elastic columns made of an elastic material such as rubber or latex. In this case, the multiple elastic columns are spaced apart along the circumference of the core shaft. For example, the elastic element 50 may be a spring, which is sleeved on the outside of the housing 21.

[0113] In some embodiments, see Figure 5 , Figure 5 for Figure 4 The structure at A is enlarged in the figure. To facilitate relative sliding between the housing 21 and the core shaft 11, the mover assembly 2 of the motor 10 includes a housing 21 and a magnetic member 22. The stator assembly 1 includes a core shaft 11 and a winding assembly 12.

[0114] The winding assembly 12 is provided on the core shaft 11. The magnetic member 22 is fixed on the housing 21. For example, the magnetic member 22 is provided on the inner circumference of the housing 21. The magnetic member 22 is located between the housing 21 and the winding assembly 12.

[0115] Specifically, the housing 21 includes a mounting hole 211 arranged along the axial direction of the core shaft 11. The mounting hole 211 is connected to the internal space of the housing 21. The core shaft 11 is inserted into the mounting hole 211, and the winding assembly 12 is located in the housing 21.

[0116] In some examples, the core shaft 11 includes a first shaft segment 111 and a second shaft segment 112. The first shaft segment 111 is inserted into the mounting hole 211 and is slidably connected to the housing 21. Specifically, a portion of the first shaft segment 111 is located outside the housing 21. The second shaft segment 112 is located inside the housing 21. The winding assembly 12 is connected to the second shaft segment 112. Thus, the winding assembly 12 is located inside the housing 21. The first shaft segment 111 can be connected to the fixing base 20.

[0117] The motor 10 also includes an iron core 121. Specifically, the stator assembly 1 includes the iron core 121. The iron core 121 is connected to the core shaft 11. For example, the iron core 121 is connected to the second shaft section 112 of the core shaft 11. Coil slots 121A are formed in the iron core 121; the winding assembly 12 is accommodated in the coil slots 121A.

[0118] Specifically, the core 121 is annular, and the core shaft 11 is inserted into and fixedly connected to the core 121. The outer wall of the core 121 is provided with a coil slot 121A, and the winding assembly 12 is disposed in the coil slot 121A and is wound around the core 121 along the circumference of the core 121.

[0119] In this way, after the winding assembly 12 is energized, a magnetic field will be generated between the winding assembly 12 and the magnetic component 22, and the direction of the Lorentz force of the magnetic field is along the axial direction of the shell 21, so that an interaction force along the axial direction of the shell 21 can be generated between the core shaft 11 and the shell 21, thereby pushing the core shaft 11 and the shell 21 to move relative to each other along the axial direction of the shell 21, and then pushing the core shaft 11 and the shell 21 to move relative to each other, so as to realize the relative movement of the stator assembly 1 and the mover assembly 2.

[0120] Illustratively, the magnetic member 22 may be a permanent magnet, an electromagnet, an energized coil 122 , or the like.

[0121] For example, the magnetic member 22 is an annular structure, wherein the core shaft 11 , the iron core 121 and the winding assembly 12 are all inserted into the magnetic member 22 .

[0122] In some embodiments, there are multiple winding assemblies 12 , which are spaced apart along the axial direction of the housing 21 . There are also multiple magnetic members 22 , which are spaced apart along the axial direction of the housing 21 .

[0123] In some embodiments, please refer to Figure 4The motor 10 used in the suspension system also includes a conductive component 3. The conductive component 3 is fixedly connected to the stator assembly 1. One end of the conductive component 3 is adapted to be electrically connected to the motor controller, and the other end of the conductive component 3 is electrically connected to the winding assembly 12. The motor controller can transmit power signals and control signals to the winding assembly 12 through the conductive component 3 to energize the winding assembly and control the magnitude of the current, thereby generating a magnetic field between the winding assembly and the magnetic member 22, thereby causing relative motion between the stator assembly 1 and the mover assembly 2.

[0124] In the related art, for example, in the patent with publication number JP2012177453A, after the wiring such as enameled wire is connected to the coil, it is led out to the outside through the through hole in the rod. The wiring is not fixed in the hole in the rod. That is, it is connected between the stator winding and the motor controller by a swinging wire method. In this way, when the enameled wire is installed in the stator assembly 1, the enameled wire needs to be sealed. However, since the enameled wire is relatively soft, the enameled wire is easy to swing, which makes it inconvenient to seal the enameled wire, which will affect the safety of the motor 10.

[0125] In order to solve the above technical problems, in some embodiments, please refer to Figure 4 and Figure 7 , Figure 7 for Figure 4 The cross-sectional view of the core shaft 11 of the motor 10 in the suspension system 300 is shown. The core shaft 11 is provided with a first cavity 113 having a first opening. At least a portion of the conductive component 3 is inserted into the first cavity 113 .

[0126] In this way, the conductive component 3 can be limited by the first chamber 113 to prevent the conductive component 3 from shaking relative to the core shaft 11, thereby facilitating the sealing of the conductive component 3.

[0127] Furthermore, by at least partially inserting the conductive assembly 3 into the first cavity 113 of the core shaft 11, the assembly of the conductive assembly 3 is simplified and easy to perform, facilitating the overall assembly of the stator assembly 1 and subsequent maintenance operations. Furthermore, the space utilization at the core shaft 11 is improved, making the stator assembly 1 more compact and facilitating the miniaturization of the motor 10.

[0128] The first chamber 113 extends axially along the core shaft 11. The conductive component 3 is also arranged axially along the core shaft 11. One axial end of the conductive component 3 is located within the first chamber 113 and extends to the iron core 121 to be electrically connected to the winding component 12. The other axial end of the conductive component 3 is located outside the first chamber 113 to be electrically connected to the motor controller. Alternatively, the other axial end of the conductive component 3 is also located within the first chamber 113 and is electrically connected to the motor controller by other electrical connection structures.

[0129] In some embodiments, see Figure 4 、 Figure 8 and Figure 9 , Figure 8 for Figure 4 A schematic structural diagram of a conductive component 3 of the motor 10 in the suspension system 300 is shown. Figure 9 for Figure 8 Schematic diagram of the structure at section EE. The conductive assembly 3 includes multiple conductive members 31 and a rigid insulating member 32. At least a portion of the multiple conductive members 31 is disposed within the first chamber 113. One end of the multiple conductive members 31 extends through the first opening to electrically connect to the motor controller, while the other end of the multiple conductive members 31 is electrically connected to the winding assembly 12. The conductive members 31 are used to deliver current to the winding assembly 12, thereby energizing the winding assembly 12.

[0130] At least part of the plurality of conductive members 31 is disposed in the first chamber 113. The plurality of conductive members 31 are disposed at intervals, thereby improving the safety of the plurality of conductive members 31.

[0131] At least a portion of the rigid insulating member 32 is disposed in the first chamber 113, and the rigid insulating member 32 covers at least a portion of the outer periphery of the plurality of conductive members 31. The outer edge of the rigid insulating member 32 directly or indirectly seals the first opening.

[0132] By arranging the hard insulating member 32 on the outer periphery of the plurality of conductive members 31, the hard insulating member 32 can support and fix the plurality of conductive members 31, and the outer edge of the hard insulating member 32 directly or indirectly seals the first opening. In this way, when sealing the gap between the hard insulating member 32 and the cavity wall of the first chamber 113, the hard insulating member 32 has a certain hardness and is not prone to shaking, thereby improving the sealing effect of the gap between the hard insulating member 32 and the cavity wall of the first chamber 113, thereby avoiding damage to the motor and increasing the service life of the motor.

[0133] Furthermore, the hard insulating member 32 is not prone to shaking and can reduce shaking of the conductive member 31 , thereby facilitating sealing of the conductive member 31 .

[0134] In some embodiments, see Figure 6 , Figure 6 for Figure 4 The motor 10 further includes a sealing member 5 . The sealing member 5 is disposed between the rigid insulating member 32 and the wall of the first chamber 113 . That is, the rigid insulating member 32 seals the first opening through the sealing member 5 .

[0135] By at least partially positioning the hard insulating member 32 within the first chamber 113 and the sealing member 5 between the hard insulating member 32 and the wall of the first chamber 113, the sealing member 5 can seal the gap between the hard insulating member 32 and the wall of the first chamber 113. Furthermore, by at least partially positioning the plurality of conductive members 31 within the first chamber 113 and at least partially positioning the hard insulating member 32 around the periphery of the plurality of conductive members 31, the hard insulating member 32 can support and secure the plurality of conductive members 31, thereby reducing any shaking of the conductive members 31.

[0136] In this way, after the seal 5 seals the gap between the hard insulating member 32 and the wall of the first chamber 113, the portion of the conductive member 31 located within the first chamber 113 can be sealed within the first chamber 113, thereby protecting the conductive member 31 and preventing external impurities from entering the first chamber 113 and damaging the conductive member 31, thereby preventing damage to the motor and ensuring that the motor controller can transmit current to the winding assembly 12 through the conductive member 31. Because the hard insulating member 32 has a certain degree of hardness and is not prone to shaking, it is convenient to seal the gap between the hard insulating member 32 and the wall of the first chamber 113, thereby facilitating the sealing of the conductive member 31.

[0137] In some examples, the hard insulating member 32 is fixedly connected to the stator assembly 1. By fixing the hard insulating member 32 to the stator assembly 1, the conductive member 31 can be fixed to the stator assembly 1 via the hard insulating member 32, so that the conductive member 31 does not shake relative to the stator assembly 1, thereby improving the sealing performance of the conductive member 31.

[0138] In some examples, the conductive member 31 may be an enameled wire. For example, the conductive member 31 may include a copper wire and an insulating layer wrapped around the copper wire. In other examples, the conductive member 31 may also be a conductive metal, for example, the conductive member 31 may be a copper busbar.

[0139] In some examples, the material of the hard insulating member 32 may be plastic, rubber, etc.

[0140] In some examples, the hard insulating member 32 covers at least a portion of the conductive member 31. For example, the hard insulating member 32 covers the entire conductive member 31. In this case, other conductive structures can extend into the hard insulating member 32 to connect the conductive member 31 to the motor controller, and to connect the conductive member 31 to the winding assembly 12. For another example, the hard insulating member 32 covers the middle portion of the conductive member 31, so that the two ends of the conductive member 31 respectively emerge from the hard insulating member 32, facilitating the connection between the motor controller and the winding assembly 12. For another example, the hard insulating member 32 can also cover the entire conductive member 31 along the axial direction of the conductive member 31, and cover a portion of the conductive member 31 along the circumferential direction of the conductive member 31.

[0141] By covering at least a portion of the conductive member 31 with the hard insulating member 32, the hard insulating member 32 can enhance the support and fixation of the conductive member 31, further enhancing the sealing effect of the conductive member 31, thereby improving the safety of the motor 10. Furthermore, at least a portion of the conductive member 31 is located within the core shaft 11, providing a good seal for the conductive member 31.

[0142] In some embodiments, the hard insulating member 32 is fixedly connected to the plurality of conductive members 31 and the core shaft 11. For example, the hard insulating member 32 can be integrally formed with the plurality of conductive members 31 and then connected to the core shaft 11 by screwing, clamping, or the like.

[0143] As another example, the plurality of conductive members 31 are at least partially embedded within the hard insulating member 32, and the hard insulating member 32 is bonded and sealed to the inner wall of the core shaft 11 (i.e., the wall of the first chamber 113). The hard insulating member 32 is bonded and sealed to the core shaft 11, and the conductive member 31 is fixed by being embedded within the hard insulating member 32. This allows the conductive member 31 to be more firmly fixed to the core shaft 11.

[0144] For example, the rigid insulating member 32 can be a sealant. By filling the sealant between the walls of the first chamber 113 and the conductive member 31, the sealant solidifies to form a rigid insulating member 32 having a certain degree of hardness and insulating properties. Furthermore, the sealant can also bond the conductive member 31 to the walls of the first chamber 113.

[0145] As another example, the plurality of conductive members 31 are at least partially embedded in the hard insulating member 32, and the outer surface of the hard insulating member 32 abuts the core shaft 11, that is, the hard insulating member 32 abuts and seals against the cavity wall of the first chamber 113. For example, the hard insulating member 32 may be an injection molded part. That is, the injection molded part is encapsulated by the plurality of conductive members 31 through injection molding, so that the injection molded part and the plurality of conductive members 31 form a single unit, namely, the conductive assembly 3. The conductive assembly 3 is then installed in the first chamber 113, and the injection molded part is abutted and sealed against the cavity wall of the first chamber 113, thereby achieving a fixed seal between the injection molded part and the core shaft 11.

[0146] Through the above arrangement, the conductive component 3 can be processed separately and then installed in the first chamber 113 . The processing technology is relatively simple, the assembly is convenient, and the insulation performance of the conductive part 31 is good.

[0147] In some examples, the multiple conductive members 31 are sealed and fixedly connected to the rigid insulating member 32. For example, at least a portion of the multiple conductive members 31 is non-removably embedded within the rigid insulating member 32. For example, the multiple conductive members 31 are injection molded into the rigid insulating member 32. Thus, the rigid insulating member 32 and the conductive members 31 form an integral structure. In this case, the conductive members 31 may or may not have an insulating layer.

[0148] Exemplarily, the plurality of conductive members 31 are detachably fixedly connected to the hard insulating member 32. For example, an accommodation space is provided in the hard insulating member 32, and the plurality of conductive members 31 are detachably connected to the accommodation space by means of snap connection, plug connection, etc.

[0149] In some embodiments, please refer to Figure 6 and Figure 8 The rigid insulating member 32 includes a sealing portion 32A. The sealing portion 32A is disposed within the first chamber 113, and the sealing member 5 is disposed between the sealing portion 32A and the wall of the first chamber 113. The sealing member 5 seals the gap between the sealing portion 32A and the wall of the first chamber 113, thereby sealing at least a portion of the conductive member 31 within the first chamber 113, thereby protecting the conductive member 31.

[0150] In some examples, the sealing portion 32A may be part of the hard insulating member 32. For example, the sealing portion 32A is formed at one end of the hard insulating member 32. In this case, the sealing portion 32A is provided at the end of the first chamber 113 along the axial direction of the core shaft 11. In this way, the sealing portion 32A can be sealed against the cavity wall of the first chamber 113 by the sealing member 5. Only the end of the hard insulating member 32 and the cavity wall of the end of the first chamber 113 are sealed, which can reduce the sealing area and improve the convenience of sealing. In some other examples, the sealing portion 32A may also be the entire outer circumference of the hard insulating member 32. In this case, the entire outer circumference of the hard insulating member 32 is sealed against the cavity wall of the first chamber 113, which can improve the sealing effect. Among them, the hard insulating member 32 may be a cylindrical structure.

[0151] In some examples, the sealing portion 32A partially wraps around the conductive member 31. For example, the sealing portion 32A completely wraps around the conductive member 31 along the circumference of the core shaft 11, but only partially wraps around the conductive member 31 along the axial direction of the core shaft 11. For another example, the sealing portion 32A completely wraps around the conductive member 31 along the axial direction of the core shaft 11, but only partially wraps around the conductive member 31 along the circumference of the core shaft 11.

[0152] By wrapping the conductive member 31 with the sealing portion 32A, the connection between the sealing portion 32A and the conductive member 31 can be made more stable, thereby making it easier to seal the gap between the sealing portion 32A and the cavity wall of the first chamber 113 .

[0153] In some examples, the sealing member 5 includes a sealing ring. Alternatively, the sealing member 5 includes a sealant.

[0154] In some embodiments, see Figure 10 , Figure 10 for Figure 8 The schematic diagram of the structure of the conductive member 31 of the conductive assembly 3 is shown. In the axial direction of the core shaft 11, the conductive member 31 includes a first conductive head 311, a first conductive body 312, and a conductive pin 313. The first conductive head 311, the first conductive body 312, and the conductive pin 313 are connected in sequence.

[0155] See also Figure 11 , Figure 11 for Figure 8 The hard insulating member 32 of the conductive component 3 is shown in FIG. The hard insulating member 32 may be an injection molded part. The hard insulating member 32 includes a head 321A, a first body portion 321B, and a pin portion 321C. Figure 10 and Figure 11 The head portion 321A at least partially wraps around the periphery of the first conductive contacts 311 and insulates and separates the plurality of first conductive contacts 311. Portions of the first conductive contacts 311 may be exposed from the head portion 321A. The first body portion 321B completely wraps around the first conductive body 312. The pin portion 321C wraps around the conductive pin 313, with the conductive pin 313 partially exposed from the pin portion 321C for electrical connection to the winding assembly 12.

[0156] In some examples, the first conductive head 311 of the conductive member 31 can be exposed from the head portion 321A of the rigid insulating member 32 to facilitate electrical connection between the conductive member 31 and the motor controller. Furthermore, the first conductive head 311 is connected to the motor controller only through the electrical connection point on the first conductive head 311 , while the rest of the first conductive head 311 excluding the electrical connection point is still covered by the head portion 321A of the rigid insulating member 32 .

[0157] The conductive pins 313 of the conductive member 31 are exposed from the pin portion 321C of the rigid insulating member 32, thereby electrically connecting the conductive member 31 to the winding assembly 12. Furthermore, the conductive pins 313 are connected to the winding assembly 12 only through the electrical connection points on the conductive pins 313. Except for the electrical connection points, the rest of the conductive pins 313 remain covered by the pin portion 321C of the rigid insulating member 32. The rigid insulating member 32 covers the entire conductive member 31, except for the necessary electrical connection points. This improves the insulation protection of the conductive member 31 and enhances the stability of the rigid insulating member 32 in supporting the conductive member 31.

[0158] In some examples, the conductive assembly 3 is arranged axially along the core shaft 11. The conductive member 31 and the hard insulating member 32 both extend axially along the core shaft 11. One axial end of the hard insulating member 32 is a head portion 321A, and the other axial end is a pin portion 321C. One axial end of the conductive member 31 is a first conductive head 311, and the other axial end is a conductive pin 313. One axial end of the conductive member 31 extends to the iron core 121 to electrically connect to the winding assembly 12. The other axial end of the conductive member 31 is electrically connected to the motor controller.

[0159] In some examples, the first conductive body 312 of the conductive member 31 is embedded in the first main body 321B of the rigid insulating member 32. The extension direction of the conductive body is not limited, as long as the ends of the conductive body are respectively connected to the first conductive head 311 and the conductive pin 313. When there are multiple conductive members 31, the first conductive bodies 312 of each conductive member 31 do not contact or interfere with each other.

[0160] In some embodiments, at least a portion of the head portion 321A is disposed within the first chamber 113, and the sealant 5 is disposed between the perimeter of the first chamber 113 wall and the head portion 321A. Specifically, the head portion 321A forms the sealing portion 32A of the rigid insulating member 32. The sealant 5 can seal the gap between the wall of the first chamber 113 and the head portion 321A, thereby sealing and protecting the first conductive body 312.

[0161] In some embodiments, please refer to Figure 6 The head portion 321A is provided with a sealing groove 321E extending along the circumference of the core shaft. The sealing groove 321E is located within the first chamber 113. The sealing member 5 is disposed within the sealing groove 321E. The sealing groove 321E serves to position the sealing member 5, thereby facilitating its placement between the head portion 321A and the wall of the first chamber 113, thereby sealing the rigid insulating member 32 and the first conductive body 312. Furthermore, the sealing groove 321E positions the sealing member 5, preventing it from deviating, thereby enhancing its sealing effectiveness.

[0162] In some examples, the first chamber 113 and the winding assembly 12 are arranged axially along the core shaft. It should be noted that the first opening of the first chamber 113 is also located at the end of the first shaft segment 111 facing away from the second shaft segment 112. That is, the conductive assembly 3 is inserted into the first chamber 113 from the end of the first chamber 113 facing away from the winding assembly 12. By providing the sealing groove 321E in the head portion 321A, the seal 5 can seal the first opening of the first chamber 113 and facilitate installation of the seal 5 within the sealing groove 321E.

[0163] The end surface of the first body portion 321B facing away from the winding assembly 12 is coplanar with the end surface of the core shaft facing away from the winding assembly. In this way, the possibility of water and sediment entering the first chamber 113 and forming a water storage area can be reduced.

[0164] In some embodiments, see Figure 7 and Figure 12 , Figure 12 for Figure 7 The schematic diagram of the top view of the core shaft 11 is shown. A plurality of inwardly projecting bosses 113A are provided within the first chamber 113. The bosses 113A are spaced apart, with a side hole defined between adjacent bosses 113A. At least a portion of the conductive component 3 is disposed within the side hole to prevent circumferential rotation of the conductive component 3.

[0165] In some examples, the cavity wall of the first chamber 113 is provided with a boss 113A, and adjacent bosses 113A define a side hole, and part of the conductive component 3 can be accommodated in the side hole to prevent the conductive component 3 from rotating circumferentially, thereby improving the assembly stability and structural stability of the conductive component 3 on the stator component 1.

[0166] In some examples, the conductive pin 313 is disposed in the side hole. Here, the conductive pin 313 can be disposed in the side hole, and the surface of the side hole in the circumferential direction of the core shaft 11 can abut against the surface of the conductive pin 313 in the circumferential direction of the core shaft 11 to limit the circumferential rotation of the conductive component 3.

[0167] In some examples, the radial spacing of the plurality of conductive pins 313 is greater than the radial spacing of the plurality of first conductive bodies 312 . Alternatively, the radial spacing of the plurality of conductive pins 313 is greater than the circumferential spacing of the plurality of first conductive bodies 312 .

[0168] In this way, the conductive pin 313 is closer to the cavity wall of the first cavity 113 than the first conductive body 312, so that the boss 113A is easily set outside the first conductive body 312 to reduce the rotation of the conductive component and improve the reliability of the motor.

[0169] In some examples, the first body portion 321B abuts against a plurality of bosses 113A. For example, the bosses 113A are provided in the first cavity 113 to abut against the hard insulating member 32 on the outer circumference of the hard insulating member 32. This can also prevent the hard insulating member 32 from shaking within the first cavity 113, thereby improving the assembly stability and structural stability of the conductive component 3 on the stator assembly 1.

[0170] In some embodiments, please refer to Figure 12 , a first fixing portion 113B is provided at the end of the first chamber 113. Figure 13 , Figure 13 for Figure 8The top view of the conductive component 3 is shown. The hard insulating member 32 is provided with a second fixing portion 321F. The second fixing portion 321F is fixed to the first fixing portion 113B.

[0171] Specifically, the core shaft 11 has a first fixing portion 113B, and the first fixing portion 113B is located in the first chamber 113 of the core shaft 11. The second fixing portion 321F can be fixedly matched with the first fixing portion 113B. For example, the first fixing portion 113B and the second fixing portion 321F can be connected by screwing, clamping, etc. In this way, the hard insulating part 32 can be fixed to the core shaft 11, thereby improving the stability of the connection between the hard insulating part 32 and the core shaft 11, so that the connection between the conductive component 3 and the stator component 1 is more stable, so as to facilitate the sealing of the conductive component 31. In addition, the first fixing portion 113B is arranged in the first chamber 113, which does not occupy the external space of the core shaft 11, which is conducive to improving space utilization.

[0172] In some examples, the first fixing portion 113B and the core shaft 11 are integrally formed. Specifically, the first fixing portion 113B is connected to the wall of the first chamber 113. Here, one end of the first fixing portion 113B can be connected to the wall of the first chamber 113, and the other end of the first fixing portion 113B can extend toward the inside of the first chamber 113.

[0173] Furthermore, the number of the first fixing portions 113B can be multiple, for example, the number of the first fixing portions 113B can be two. By having multiple first fixing portions 113B, the installation firmness of the conductive component 3 can be improved.

[0174] The first fixing portion 113B and the core shaft 11 are integrally formed, resulting in a high structural strength. This reduces the likelihood of separation between the first fixing portion 113B and the core shaft 11, thereby increasing the support strength of the first fixing portion 113B on the hard insulating member 32, thereby ensuring a more stable connection of the conductive component 3 to the stator assembly 1. Furthermore, by integrally forming the first fixing portion 113B and the core shaft 11, the integration of the core shaft 11 is increased, the number of components in the motor 10 is reduced, and the assembly steps for the components of the motor 10 are simplified, thereby improving the production and assembly efficiency of the motor 10.

[0175] In some examples, the second fixing portion 321F is a fixing hole provided in the head portion 321A. For example, a hole can be provided in the first fixing portion 113B, and the second fixing portion 321F is located in the head portion 321A of the hard insulating member 32 and is configured as a fixing hole. A fastener can be inserted through the hole and the fixing hole to securely connect the conductive component 3 to the core shaft 11.

[0176] In some embodiments, when the conductive component 3 is mated with the core shaft 11, the head 321A of the hard insulating component 32 is located on the outside of the first fixing portion 113B in the axial direction of the core shaft 11. At this time, the head 321A of the hard insulating component 32 is arranged closer to the end of the core shaft 11 than the first fixing portion 113B. The fastener is passed through the fixing hole and the hole body in sequence from the end of the core shaft 11 to fix the conductive component 3 to the core shaft 11.

[0177] In some embodiments, there are two first fixing parts 113B and two second fixing parts 321F, and the two second fixing parts 321F and the two first fixing parts 113B are fixed one by one. Multiple fixing parts can increase the connection points between the hard insulating part 32 and the core shaft 11, thereby enhancing the connection stability and connection strength between the conductive component 3 and the core shaft 11.

[0178] In some embodiments, please refer to Figure 11 The first body portion 321B is provided with an escape channel 321G for circumventing the first fixing portion 113B, thereby avoiding the first fixing portion 113B when the conductive component 3 is inserted into the first cavity 113. It is understood that the conductive component 3 and the first cavity 113 both extend axially along the core shaft 11, and the conductive component 3 is assembled into the first cavity 113 along the axial direction of the core shaft 11. Since the first fixing portion 113B is provided on the inner wall of the first cavity 113, to prevent the first fixing portion 113B from interfering with the assembly of the conductive component 3, the escape channel 321G is provided in the hard insulating component 32. This allows the first body portion 321B and the pin portion 321C to extend into the interior of the first cavity 113 during assembly of the conductive component 3. Furthermore, the provision of the escape channel 321G can also reduce the weight of the hard insulating component 32, thereby achieving a lightweight stator assembly 1, and thus a lightweight motor 10.

[0179] In some embodiments, the seal 5 is located closer to the end of the core shaft 11 that faces the motor controller than the first fixing portion 113B. This position of the seal 5 closer to the end of the core shaft 11 allows it to seal a larger portion of the conductive member 31 and the first fixing portion 113B, thereby improving the sealing effect.

[0180] In some embodiments, see Figure 14 , Figure 14 for Figure 11The following diagram illustrates the structure of the rigid insulating member 32 from an opposite side perspective. Ribs 321H are provided on the outer surface of the rigid insulating member 32. The provision of ribs 321H enhances the structural strength of the rigid insulating member 32, providing better support for the conductive member 31 and ensuring a consistent distance between the conductive member 31 and the first portion. Furthermore, the provision of ribs 321H allows the rigid insulating member 32 to fit more tightly against the walls of the first chamber 113, thereby enhancing the stability of the connection between the rigid insulating member 32 and the core shaft 11.

[0181] In some examples, the number of the rib 321H may be one or more.

[0182] In some examples, the ribs 321H extend axially of the mandrel 11. In other examples, the ribs 321H extend circumferentially of the mandrel 11. In still other examples, there are multiple ribs 321H, with some ribs 321H extending axially of the mandrel 11 and others extending radially of the mandrel 11.

[0183] In some embodiments, please refer to Figure 7 The core shaft 11 is provided with a first through hole 11A radially extending therethrough, and the conductive pin 313 is electrically connected to the lead wire of the winding assembly 12 via an electrical connector passing through the first through hole 11A.

[0184] Specifically, the winding assembly 12 is generally sleeved on the outer circumference of the core shaft 11, and the lead wires on the winding assembly 12 are also located radially outside the core shaft 11. To facilitate electrical connection between the lead wires and the conductive component 3 within the first cavity 113 inside the core shaft 11, a first through hole 11A is provided in the core shaft 11, connecting the space outside the core shaft 11 with the first cavity 113. In this case, the lead wires can pass through the first through hole 11A and extend into the first cavity 113, thereby electrically connecting with the conductive pin 313.

[0185] The conductive pin 313 of the conductive component 3 is electrically connected to the lead wire of the winding component 12. The two can be directly connected. For example, the conductive pin 313 can extend from the first through hole 11A to the outer space of the core shaft 11 to be electrically connected to the lead wire, or the lead wire can extend into the first cavity 113 to be electrically connected to the conductive pin 313.

[0186] Of course, the conductive pins 313 of the conductive component 3 and the lead wires of the winding component 12 may also be electrically connected via other conductive structures.

[0187] Here, see Figure 15 , Figure 15 for Figure 4A schematic diagram of the structure at point G in the middle is enlarged. To facilitate processing, an electrical connector 6 is provided. The electrical connector 6 is provided through the first through hole 11A and is connected to the lead wire 122A and the conductive component 3, respectively. It is understandable that the lead wire 122A generally extends in the axial direction of the core shaft 11, and the conductive component 3 also extends in the axial direction of the core shaft 11 along the first cavity 113. Therefore, in theory, the lead wire 122A and the conductive component 3 are arranged approximately in parallel. The electrical connector 6 can electrically connect the end of the lead wire 122A to the portion of the conductive pin 313 exposed in the first through hole 11A, facilitating the connection between the lead wire 122A and the conductive component 3, making processing easy and having high process feasibility.

[0188] In some embodiments, the electrical connector 6 may extend in the radial direction of the core shaft 11 , and two ends of the electrical connector 6 are fixedly connected to the lead wire 122A and the conductive pin 313 , respectively.

[0189] In some embodiments, the electrical connector 6 is a conductive structure.

[0190] In some embodiments, the electrical connector 6 is covered with an insulating structure to prevent electrical leakage and short circuits caused by external impurities, thereby ensuring the operational stability of the electrical connector 6. The portion of the electrical connector 6 connected to the lead wire 122A and the portion of the electrical connector 6 connected to the conductive pin 313 are both exposed from the insulating structure to electrically connect the lead wire 122A to the conductive pin 313.

[0191] In some embodiments, the lead wire 122A is covered with an insulating structure to prevent leakage and short circuit. The portion of the lead wire 122A connected to the electrical connector 6 is exposed from the insulating structure to facilitate electrical connection with the electrical connector 6.

[0192] In some embodiments, the first through hole 11A is located at the bottom of the first cavity 113. Here, the first cavity 113 extends axially along the core shaft 11, and the conductive component 3 is also arranged axially along the core shaft 11. The first through hole 11A is provided at the bottom of the first cavity 113, so that the conductive component 3 and / or the lead wire 122A do not need to be bent to adapt to the position of the first through hole 11A, simplifying the process design of the conductive component 3 and the lead wire 122A and ensuring the structural strength of the conductive component 3 and the lead wire 122A.

[0193] In some embodiments, the electrical connector 6 is welded to the lead wire 122A and the conductive pin 313, respectively, to ensure the connection strength between the electrical connector 6, the lead wire 122A, and the conductive pin 313, and to prevent the electrical connector 6 from separating from the lead wire 122A or the conductive pin 313 during use of the motor 10, thereby ensuring the operational stability and reliability of the motor 10. In other embodiments, the electrical connector 6 and the lead wire 122A may be connected by screwing, riveting, or other means. The electrical connector 6 and the conductive pin 313 may also be connected by screwing, riveting, or other means.

[0194] In some embodiments, see Figure 16 , Figure 16 for Figure 15 The electrical connector 6 is shown as a schematic diagram. The electrical connector 6 includes a first connector 61 and a second connector 62. At least one of the first connector 61 and the second connector 62 extends axially along the core shaft 11. The first connector 61 is connected to the conductive pin 313, and the second connector 62 is connected to the lead wire 122A.

[0195] In some examples, the first connector 61 and the conductive pin 313 can be connected by screwing, welding, riveting, etc. The second connector 62 and the lead wire 122A can also be connected by screwing, welding, riveting, etc. Here, the first connector 61 and the conductive pin 313 are welded, and the second connector 62 and the lead wire 122A are welded for example.

[0196] Specifically, a first connector 61 and a second connector 62 are provided at both ends of the electrical connector 6 in the extension direction. For example, the surface of the second connector 62 facing the lead wire 122A serves as the welding surface for the second connector 62 and the lead wire 122A. The second connector 62 is designed to be located at one end of the electrical connector 6 and extend axially along the core shaft 11 to increase the area of ​​the welding surface, improve the connection stability of the welding connection, and facilitate the welding operation. The first connector 61 can also extend axially along the core shaft 11. This design also has the effect of improving the stability of the welding connection between the first connector 61 and the conductive component 3 and facilitating the welding operation between the first connector 61 and the conductive component 3.

[0197] In some embodiments, the first connector 61 and the second connector 62 are formed by bending two ends of the electrical connector 6 axially toward the core shaft 11 .

[0198] In some embodiments, see Figure 7 and Figure 17 , Figure 17 for Figure 4The schematic diagram of the top view of the motor 10 is shown. A first stopper 11B is provided on the outer peripheral wall of the core shaft 11. The first stopper 11B is located on the side of the winding assembly 12 facing the first chamber 113. The first stopper 11B and the first through hole 11A are located at the same axial height of the core shaft 11.

[0199] In some embodiments, the second connector 62 is located on a side of the first limiting member 11B facing the first chamber 113 , and the lead wire 122A extends to an end surface of the first limiting member 11B to connect with the second connector 62 .

[0200] In some embodiments, the electrical connector 6 is placed on the first limiting member 11B, the second connector 62 is located on the side of the first limiting member 11B facing the first chamber 113 , and the lead wire 122A extends to the end surface of the first limiting member 11B to connect with the second connector 62 .

[0201] To prevent the winding assembly 12 from moving axially along the core shaft 11, a first stopper 11B is provided. The first stopper 11B is adapted to engage with the axial end of the winding assembly 12, thereby preventing the winding assembly 12 from moving axially along the core shaft 11. Furthermore, because the portion where the lead wire 122A connects to the electrical connector 6 is conductive, to ensure overall insulation, the connection point between the lead wire 122A and the electrical connector 6 should be a certain distance from the outer periphery of the winding assembly 12. Therefore, the lead wire 122A is designed to extend toward the end face of the first stopper 11B to facilitate connection with the second connector 62.

[0202] Here, the first limiting member 11B and the winding assembly 12 may be in a stop fit, a snap fit, or other fit modes.

[0203] At the same time, in some embodiments, in order to fix the winding assembly 12 to the outer surface of the core shaft 11, the cross-section of the portion where the core shaft 11 cooperates with the winding assembly 12 can be a non-circular shape such as a rectangle or a pentagon to limit the circumferential rotation of the winding assembly 12 relative to the core shaft 11; or, the winding assembly 12 can be provided with a first positioning member, and the core shaft 11 can be provided with a second positioning member, and the first positioning member cooperates with the second positioning member to limit the circumferential rotation of the winding assembly 12 relative to the core shaft 11.

[0204] In some embodiments, the motor 10 further includes an iron core 121. The iron core 121 is sheathed on the core shaft 11. The second connector 62 extends along the axial direction of the core shaft 11 and has a first welding surface for welding to the lead wire 122A. Figure 17 , along the axial direction of the core shaft (11), the projection of the first welding surface is radially inside the outer edge of the projection of the iron core 121 and the radial distance from the outer edge is a, a≥2mm.

[0205] Specifically, in order to ensure the implementation of the welding process between the electrical connector 6 and the lead wire 122A, the welding point between the electrical connector 6 and the lead wire 122A should not be too close to the core shaft 11 to prevent the welding gun from failing to work. Here, the minimum distance between the welding point between the electrical connector 6 and the lead wire 122A and the outer surface of the core shaft 11 needs to be determined with reference to the welding gun specifications, and this distance is not limited here; the part where the lead wire 122A is connected to the electrical connector 6 is conductive. In order to ensure the overall insulation effect, the distance a between the welding point between the lead wire 122A and the electrical connector 6 and the outer periphery of the winding assembly 12 should be no less than 2 mm to ensure the stability of the welding connection and the overall insulation effect, and to facilitate the welding operation.

[0206] Exemplarily, the radial spacing a between the orthographic projection of the first welding surface and the outer edge of the orthographic projection of the iron core 121 can be 2 mm, 3 mm, 3.5 mm, etc., so that when the radial spacing between the orthographic projection of the first welding surface and the outer edge of the orthographic projection of the iron core 121 is a, the welding gun can weld the electrical connector 6 to the lead wire 122A.

[0207] In some embodiments, the first connector 61 extends into the first cavity 113 to connect with the conductive pin 313. Here, the portion of the first connector 61 that connects to the conductive pin 313 is conductive. Designing the first connector 61 to extend into the first cavity 113 to connect with the conductive pin 313 can prevent leakage, ensure creepage distance, and protect the electrical connector 6 from being scratched.

[0208] In some embodiments, see Figure 18 , Figure 18 for Figure 8 Enlarged schematic diagram of the structure at H in the middle. The hard insulating part 32 is provided with a avoidance hole 321K for exposing the conductive part 31. The first connector 61 is located in the avoidance hole 321K to connect with the conductive part 31. It can be understood that in order to ensure the overall insulation effect while satisfying the electrical connection conditions between the conductive part 31 and other structures, the avoidance hole 321K provided on the hard insulating part 32 only needs to expose the electrical connection point of the conductive part 31. In some embodiments, the pin portion 321C of the hard insulating part 32 is provided with the above-mentioned avoidance hole 321K, and the avoidance hole 321K exposes the electrical connection point of the conductive part 31 located inside the hard insulating part 32, so that the electrical connector 6 electrically connects the conductive part 31 to the lead wire 122A.

[0209] In some embodiments, the conductive member 31 is provided with a connection hole 31B that communicates with the avoidance hole 321K. The outer peripheral wall of the first connector 61 is connected to the hole wall of the connection hole 31B. In some embodiments, the portion of the hard insulating member 32 exposed from the first through hole 11A is provided with the avoidance hole 321K, while the portion of the conductive member 31 exposed from the avoidance hole 321K is provided with the connection hole 31B. The first connector 61 is adapted to be received in the connection hole 31B. The first connector 61 can be welded to the connection hole 31B to connect the electrical connector 6 to the conductive component 3. Here, to facilitate the welding operation, the area of ​​the portion of the hard insulating member 32 exposed from the first through hole 11A should be larger than the area of ​​the connection hole 31B.

[0210] In some embodiments, the hole wall of the connecting hole 31B and the outer peripheral wall of the first connecting head 61 should at least be a transition fit or an interference fit to facilitate welding operation.

[0211] In some embodiments, to ensure welding quality, the front end surface of the first connector 61 and the front end surface of the connection hole 31B are on the same plane. This design can also increase the creepage distance.

[0212] In some embodiments, the avoidance hole 321K is located radially inward of the first through-hole 11A in the radial direction of the core shaft 11. As previously described, the portion of the hard insulating member 32 exposed from the first through-hole 11A is provided with the avoidance hole 321K, while the portion of the conductive member 31 exposed from the avoidance hole 321K is provided with the connection hole 31B. The connection hole 31B communicates with the avoidance hole 321K. To facilitate welding, the avoidance hole 321K is connected to the first through-hole 11A, allowing for welding of the first connector 61 to the connection hole 31B.

[0213] In addition, the conductive pin 313 of the conductive part 31 is exposed in the avoidance hole 321K of the hard insulating part 32. To facilitate welding and prevent the hard insulating part 32 from failing due to heat during the welding operation, the area of ​​the conductive pin 313 exposed in the avoidance hole 321K should be larger than the area of ​​the connecting hole 31B.

[0214] According to some embodiments of the present invention, the electrical connector 6 and the hole wall of the first through hole 11A are spaced apart to ensure an electrical gap.

[0215] In some embodiments, please refer to Figure 17 The minimum spacing b between the electrical connector 6 and the wall of the first through hole 11A is b, b≥5mm, to ensure electrical clearance and insulation effect. Exemplarily, the minimum spacing b between the electrical connector 6 and the wall of the first through hole 11A can be 5mm, 5.5mm, 6mm, etc. It can be understood that the spacing between the electrical connector 6 and the wall of the first through hole 11A should not be too large to ensure that the stator assembly 1 is small in size, small in volume, and lightweight.

[0216] In some embodiments, please refer to Figure 11 The first conductive head 311 includes a first electrical connection end 311A ​​and a second electrical connection end 311B. The first electrical connection end 311A ​​and the second electrical connection end 311B are staggered in the axial direction of the core shaft 11 and are suitable for electrically connecting to the motor controller.

[0217] In some embodiments, the motor controller is electrically connected to the first conductive head 311 via the plug connector 7. Specifically, the first electrical connection end 311A ​​and the second electrical connection end 311B are adapted to be electrically connected to the plug connector 7. To ensure that the highest point of the plug connector 7 is no more than 40 mm from the end face of the core shaft 11 after the motor 10 is assembled, the first electrical connection end 311A ​​and the second electrical connection end 311B are designed to be staggered in the axial direction of the core shaft 11. Furthermore, the staggered arrangement of the first electrical connection end 311A ​​and the second electrical connection end 311B in the axial direction of the core shaft 11 facilitates the mating of the plug connector with the first conductive head 311, achieving a fool-proof design and improving installation efficiency.

[0218] In some embodiments, please refer to Figure 4 The core shaft 11 includes a first shaft segment 111 and a second shaft segment 112. The first chamber 113 is provided in the first shaft segment 111, and the winding assembly is provided in the second shaft segment 112. The second shaft segment 112 is provided with a guide hole 112A. The mover assembly 2 includes a guide rod 23. The guide rod 23 is provided in the guide hole 112A. Specifically, the guide rod 23 can slide in the guide hole 112A. By sliding the guide rod 23 in the guide hole 112A, the stator assembly 1 and the mover assembly 2 can be guided when the stator assembly 1 and the mover assembly 2 move relative to each other, so as to improve the stability of the relative movement of the stator assembly 1 and the mover assembly 2.

[0219] In some embodiments, please refer to Figure 7 A vent portion 11C is provided between the first chamber 113 and the guide hole 112A. A vent hole 11D is provided in the vent portion 11C, which connects the first chamber 113 and the guide hole 112A. The provision of the vent hole 11D allows the air in the guide hole 112A to flow between the first chamber 113 and the guide hole 112A as the guide rod 23 slides in the guide hole 112A, thereby preventing the air in the guide hole 112A from being compressed and causing greater resistance to the guide rod 23. This reduces the resistance during the relative movement of the stator assembly 1 and the mover assembly 2, thereby ensuring smooth relative movement of the stator assembly 1 and the mover assembly 2.

[0220] In some examples, at least a portion of the vent portion 11C is disposed in the first chamber 113 . That is, the vent portion 11C may be a protrusion that protrudes from the guide hole 112A toward the first chamber 113 into the first chamber 113 .

[0221] In some embodiments, a gap is formed between the surface of the hard insulating member 32 facing the second shaft segment 112 and the surface of the vent portion 11C facing away from the second shaft segment 112. This prevents the hard insulating member 32 from blocking the vent hole 11D, thereby ensuring air circulation between the first chamber 113 and the guide hole 112A.

[0222] In some examples, a gap m is defined between the surface of the rigid insulating member 32 facing the second shaft segment 112 and the surface of the vent portion 11C facing away from the second shaft segment 112, where m ≥ 10 mm. For example, the gap between the surface of the rigid insulating member 32 facing the second shaft segment 112 and the surface of the vent portion 11C facing away from the second shaft segment 112 can be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, etc.

[0223] In some other embodiments, see Figure 19 , Figure 19 This is a schematic diagram of the structure of another conductive assembly 3 provided in an embodiment of the present application. The rigid insulating member 32 may be a skeleton. An accommodating space 3221 is defined within the rigid insulating member 32. The accommodating space 3221 extends axially along the core shaft 11, and at least a portion of the conductive member 31 is disposed within the accommodating space 3221.

[0224] By limiting the conductive part 31 by the accommodating space 3221, the conductive part 31 can be more stably connected to the hard insulating part 32. Therefore, after the hard insulating part 32 is connected to the core shaft 11, the conductive part 31 can be more stably connected to the core shaft 11, so that the distance between the conductive part 31 and the first part of the displacement sensor does not change.

[0225] In some embodiments, please refer to Figure 19 In the axial direction of the core shaft 11, the conductive member 31 includes a second conductive head 314 and a second conductive body 315. The rigid insulating member 32 includes a head portion 321A and a second body portion 3223. The head portion 321A encases the second conductive head 314, with a portion of the second conductive head 314 exposed from the head portion 321A. A housing 3221 is provided in the second body portion 3223, and the second conductive body 315 is disposed within the housing 3221.

[0226] In this way, except for the part that needs to be electrically connected to the motor controller or the winding assembly 12, the conductive part 31 is fixed and limited by the hard insulating part 32, so as to enhance the protection effect of the hard insulating part 32 on the conductive part 31, and enhance the support stability of the hard insulating part 32 on the conductive part 31, thereby ensuring that the distance between the conductive part 31 and the first part of the displacement sensor does not change.

[0227] In some examples, the head portion 321A of the rigid insulating member 32 defines a through-hole that communicates with the accommodating space 3221. The second conductive contact 314 of the conductive member 31 is disposed within the through-hole, with the second conductive contact 314 partially extending outside the through-hole to facilitate connection to a motor controller. The second body portion 3223 can be completely contained within the accommodating space 3221, or it can partially extend from the end of the accommodating space 3221 facing away from the head portion 321A to connect to the winding assembly 12.

[0228] When there are multiple conductive members 31 , there are also multiple through-holes, with the second conductive head 314 of one conductive member 31 being inserted into one through-hole. Furthermore, there are also multiple accommodating spaces 3221 , with the second conductive body 315 of one conductive member 31 being accommodated in one accommodating space 3221 .

[0229] In some examples, both the conductive member 31 and the hard insulating member 32 extend axially along the core shaft 11, and the accommodating space 3221 also extends axially along the core shaft 11. More of the conductive member 31 can be accommodated in the accommodating space 3221, thereby improving the stability of the conductive member 31 on the core shaft 11.

[0230] In some examples, the accommodating space 3221 may include an accommodating groove 322A. The accommodating groove 322A extends axially along the core shaft 11. The accommodating groove 322A is recessed radially from the outer surface of the hard insulating member 32 in the core shaft 11. In other words, the hard insulating member 32 is also cylindrical in structure, and the accommodating groove 322A is provided on the outer circumference of the hard insulating member 32 and extends axially along the hard insulating member 32.

[0231] When installing the conductive member 31 into the rigid insulating member 32, one end of the conductive member 31 can be inserted from the head 321A into the receiving groove 322A. The conductive member 31 can then be continuously pushed into the receiving groove 322A along the axial direction of the core shaft 11. By configuring the receiving space 3221 as the receiving groove 322A, if the second conductive member bends or becomes stuck during its insertion into the receiving groove 322A, the second conductive member can be adjusted promptly to ensure smooth installation of the conductive member 31 into the rigid insulating member 32.

[0232] In some other examples, the accommodating space 3221 may also be an accommodating hole that extends along the axial direction of the core shaft 11 , and the conductive member 31 may be inserted into the accommodating hole to limit the conductive member 31 through the accommodating hole.

[0233] In some embodiments, please refer to Figure 19The accommodating groove 322A includes a bottom wall surface 322B and a second opening 322C arranged radially along the core shaft 11. The hard insulating member 32 also includes a stopper 3224. The stopper 3224 is provided at the second opening 322C, and the second conductive body 315 is located between the stopper 3224 and the bottom wall surface 322B. The stopper 3224 can confine the second conductive body 315 of the conductive member 31 within the accommodating groove 322A, thereby improving the stability of the second conductive body 315 within the accommodating groove 322A.

[0234] In some examples, the second conductive body 315 contacts the bottom wall surface 322B of the accommodating groove 322A and contacts the limiting portion 3224, so that the second conductive body 315 is supported and fixed by the bottom wall surface 322B of the accommodating groove 322A and the limiting portion 3224, so that the second conductive body 315 is more stable in the accommodating groove 322A.

[0235] For some examples, see Figure 19 The limiting portion 3224 includes a plurality of limiting ribs 322D arranged at intervals along the axial direction of the core shaft 11. The limiting ribs 322D may be a plate-like structure, a rod-like structure, or the like.

[0236] By providing a plurality of limiting ribs 322D, the second conductive body 315 can be effectively limited, and the second conductive body 315 can be easily adjusted during the process of installing the conductive member 31 into the hard insulating member 32 .

[0237] In some other examples, the limiting portion 3224 may also be a limiting plate covering the second opening 322C.

[0238] In some embodiments, see Figure 20 and Figure 21 , Figure 20 for Figure 19 The schematic diagram of the structure of the motor 10 after the conductive component 3 is installed on the core shaft 11 is shown. Figure 21 for Figure 20 Schematic diagram of the structure along the middle section (FF). The core shaft 11 includes a first shaft segment 111 and a second shaft segment 112. The second shaft segment 112 is disposed within the housing 21 of the movable assembly 2. The winding assembly 12 is disposed within the second shaft segment 112. A portion of the first shaft end is located outside the housing 21 of the movable assembly 2, and a first chamber 113 is disposed within the first shaft segment 111.

[0239] Please continue reading Figure 19The inner wall surface of the end of the accommodating groove 322A facing the second shaft segment 112 is a first guide surface 322E. The first guide surface 322E includes a first end 322F and a second end 322G. The second end 322G is located outside the first end 322F and on the side of the first end 322F facing the second shaft segment 112. In other words, the first guide surface 322E is inclined from the inside to the outside along the direction from the first shaft segment 111 toward the second shaft segment 112. Here, "from the inside to the outside" refers to the direction from the axis of the core shaft 11 toward the outer circumference of the core shaft 11.

[0240] See also Figure 22 , Figure 22 for Figure 19 The diagram shows the structure of the conductive member 31 of the conductive assembly 3, with the lead section extending out of the rigid insulating member 32. The conductive member 31 also includes a lead section 316. The lead section 316 extends to the exterior of the core shaft 11 via a first guide surface 322E. The first guide surface 322E allows the lead section 316 to be led from the receiving groove 322A to the exterior of the rigid insulating member 32, and then to the exterior of the core shaft 11, facilitating electrical connection between the lead section 316 and the winding assembly 12.

[0241] The first guide surface 322E is set as an inclined surface. When the lead-out section 316 is led out from the accommodating groove 322A to the outside of the hard insulating part 32, the first guide surface 322E can guide the lead-out section 316 so that the lead-out section 316 can be led out of the outside of the hard insulating part 32 along the first guide surface 322E.

[0242] For details, please refer to 18. Figure 23 and Figure 24 , Figure 23 for Figure 19 The schematic diagram of the structure of the conductive component 3 shown is a diagram of the conductive member 31 passing through the head 321A and the second conductive body 315 not completely entering the receiving groove 322A. Figure 24 for Figure 19 The second conductive body 315 of the conductive member 31 in the conductive assembly 3 is shown in the structure diagram when it enters the accommodating groove 322A but the lead section 316 is not led out to the outside of the hard insulating member 32. When installing the conductive member 31 into the hard insulating member 32, please refer to Figure 23 , insert the end of the lead section 316 of the conductive member 31 into the head 321A. Figure 24 Then, the conductive member 31 is continuously pushed along the direction of the head portion 321A toward the second body portion 3223, so that the second conductive body 315 of the conductive member 31 gradually enters the receiving groove 322A. Figure 22, continue to push the conductive member 31 along the direction of the head 321A toward the second main body 3223 until the second conductive body 315 of the conductive member 31 completely enters the accommodating groove 322A, and the lead-out section 316 will extend to the outside of the hard insulating member 32 under the guidance of the first guide surface 322E, thereby completing the installation of the conductive member 31 on the hard insulating member 32.

[0243] In some examples, the conductive member 31 extends axially along the core shaft 11, and the second conductive head 314 and the lead section 316 are respectively connected to both ends of the second conductive body 315. Specifically, the second conductive head 314 is located at the end of the second conductive body 315 facing away from the second shaft section 112, and the lead section 316 is located at the end of the second conductive body 315 facing the second shaft section 112.

[0244] For some examples, see Figure 25 , Figure 25 for Figure 21 A schematic diagram of the structure of the core shaft 11 in the motor 10 is shown. The core shaft 11 is provided with a second through hole 114 extending radially thereof. Specifically, the second through hole 114 is provided at one end of the first shaft segment 111 facing the second shaft segment 112 and is connected to the first chamber 113. The second through hole 114 corresponds to the first guide surface 322E. After the lead section 316 of the conductive member 31 is led to the exterior of the hard insulating member 32, it can extend to the exterior of the core shaft 11 through the second through hole 114 to connect to the winding assembly 12.

[0245] When there are multiple conductive members 31, the inner wall of each receiving groove 322A is provided with a first guide surface 322E, and there are multiple second through holes 114. The lead-out section 316 of each conductive member 31 extends to the exterior of the core shaft 11 through one guide surface and one second through hole 114.

[0246] In some embodiments, please refer to Figure 19 The hard insulating member 32 further includes a clamping portion 3225. The clamping portion 3225 is connected to one end of the second body portion 3223 facing the second shaft segment 112. Figure 26 and Figure 27 , Figure 26 for Figure 21 The schematic diagram of the front view of the core shaft 11 of the motor 10 is shown. Figure 27 for Figure 26 A clamping hole 115 is provided at one end of the second shaft section 112 facing the first shaft section 111 .

[0247] See also Figure 28 , Figure 28 for Figure 21The enlarged schematic diagram of the structure at point C in the middle. The clamping portion 3225 is clamped to the clamping hole 115. By clamping the clamping portion 3225 to the clamping hole 115, the connection between the hard insulating member 32 and the core shaft 11 can be facilitated and the connection of the hard insulating member 32 to the core shaft 11 can be made more stable.

[0248] For some examples, see Figure 29 , Figure 29 for Figure 19 An enlarged schematic diagram of the structure at point D in the middle. The clamping portion 3225 includes multiple elastic pieces 3225A arranged along the circumference of the core shaft 11. As a result, after the clamping portion 3225 is clamped into the clamping hole 115, the elastic action of the multiple elastic pieces 3225A causes the multiple elastic pieces 3225A to abut against the inner circumferential surface of the clamping hole 115, thereby improving the stability of the connection between the clamping portion 3225 and the clamping hole 115.

[0249] For some examples, see Figure 29 A first guide surface 3225B is provided on the outer surface of the elastic piece 3225A at the end facing away from the second body portion 3223. The distance between the first guide surface 3225B and the axis of the engaging hole 115 gradually increases as the second shaft segment 112 moves toward the first shaft segment 111. The provision of the first guide surface 3225B guides the engaging portion 3225 during engagement with the engaging hole 115, ensuring smooth and convenient entry of the engaging portion 3225 into the engaging hole 115.

[0250] Please continue reading Figure 28 The inner wall of the engaging hole 115, facing away from the second shaft segment 112, forms a second guide surface 115A. As the second shaft segment 112 moves toward the first shaft segment 111, the distance between the second guide surface 115A and the axis of the engaging hole 115 gradually increases. The provision of the second guide surface 115A guides the engaging portion 3225 during engagement with the engaging hole 115, ensuring smooth and convenient entry of the engaging portion 3225 into the engaging hole 115.

[0251] For some examples, see Figure 29 The outer surface of the elastic piece 3225A is provided with a limiting protrusion 3225C at one end facing away from the second body portion 3223. The first guide surface 322E is provided on the limiting protrusion 3225C. Figure 27 The second shaft section 112 is provided with a guide hole 112A, which is used to set the guide rod 23 of the movable assembly 2 so that the guide rod 23 slides in the guide hole 112A, thereby improving the stability of the relative sliding between the movable assembly 2 and the stator assembly 1. The clamping hole 115 connects the first chamber 113 and the guide hole 112A. Please continue to refer to Figure 28 After the clamping portion 3225 is clamped into the clamping hole 115, the limiting protrusion 3225C will pass through the clamping hole 115 and enter the guide hole 112A, and the surface of the limiting protrusion 3225C facing the first shaft segment 111 can contact the inner wall surface of the guide hole 112A facing the first chamber 113, thereby further limiting the clamping portion 3225 to further improve the stability of the connection between the clamping portion 3225 and the clamping hole 115.

[0252] In some embodiments, the head portion 321A of the rigid insulating member 32 is connected to the end of the second body portion 3223 facing away from the second shaft segment 112, and the head portion 321A is connected to the core shaft 11. Because the head portion 321A is located at the end of the second body portion 3223 facing away from the second shaft segment 112 and connected to the core shaft 11, the end of the conductive component 3 facing away from the second shaft segment 112 is also connected to the core shaft 11. Simultaneously, the end of the conductive component 3 facing the second shaft segment 112 engages with the engaging hole 115 via the engaging portion 3225, thereby enabling both ends of the conductive component 3 to be connected to the core shaft 11. This further improves the stability of the connection between the conductive component 3 and the core shaft 11, ensuring that no changes occur between the conductive component 3 and the first portion of the displacement sensor.

[0253] In some examples, the head 321A can be snap-fitted into the first chamber 113 , or can be connected by other means such as screwing, bonding, etc.

[0254] In some embodiments, see Figure 30 , Figure 30 for Figure 21 An enlarged schematic diagram of the structure at point K in the middle. The head portion 321A and the second body portion 3223 are both located within the first chamber 113. The seal 5 is positioned between the perimeter of the first chamber 113 and the head portion 321A. In other words, the head portion 321A forms the sealing portion 32A of the rigid insulating member 32. This facilitates installation of the seal 5 and effectively seals the conductive member 31.

[0255] In some embodiments, please refer to Figure 19 The conductive member 31 further includes a wiring terminal 317. The wiring terminal 317 is connected to the second conductive head 314. The wiring terminal 317 is used to connect to the motor controller. The wiring terminal 317 facilitates wiring, thereby facilitating the connection between the second conductive head 314 of the conductive member 31 and the motor controller.

[0256] In some embodiments, the outer periphery of the conductive member 31 is coated with an insulating layer. For example, the conductive member 31 may be an enameled wire, or the outer periphery of the conductive member 31 may be provided with insulating varnish or other insulating material. This insulating layer protects the conductive member 31 from leakage, thereby improving the safety of the motor 10.

[0257] On this basis, in some examples, the hard insulating member 32 is disposed between the insulating layer of the conductive member 31 and the wall of the first chamber 113. In this way, the hard insulating member 32 can also provide insulation protection for the conductive member 31, and the insulating layer around the conductive member 31 can also provide insulation protection for the hard insulating member 32, thereby further improving the insulation performance of the conductive member 31 and further enhancing the safety of the motor 10.

[0258] In some other embodiments, see Figure 31 , Figure 31 This is a schematic diagram of the structure of another conductive assembly 3 provided in an embodiment of the present application. The conductive member 31 of the conductive assembly 3 includes a third conductive body 318 and a conductive terminal 319. The conductive terminal 319 is connected to the end of the third conductive body 318 facing the winding assembly 12 and is used to connect to the winding assembly 12. The end of the third conductive body 318 facing away from the winding assembly 12 is used to connect to the motor controller.

[0259] The hard insulating member 32 wraps at least a portion of the conductive terminal 319. In this way, the hard insulating member 32 can support and fix the conductive terminal 319, thereby supporting and fixing the conductive member 31 to reduce the shaking of the conductive member 31, thereby facilitating the sealing of the conductive member 31.

[0260] In some examples, the hard insulating member 32 may be a cylindrical structure, and a plurality of insulating holes 323 are provided on the hard insulating member 32 , and a conductive terminal 319 of a conductive member 31 is passed through an insulating hole 323 , thereby fixing the conductive member 31 through the hard insulating member 32 .

[0261] In some examples, the rigid insulating member 32 may partially cover the conductive terminal 319. For example, a portion of the conductive terminal 319 may extend from the insulating hole 323 of the rigid insulating member 32 to facilitate connection to the winding assembly 12. Alternatively, the rigid insulating member 32 may completely cover the conductive terminal 319. In this case, other conductive connectors 6 may extend into the rigid insulating member 32 to connect to the conductive terminal 319 and thus connect to the winding assembly 12. By completely covering the conductive terminal 319 with the rigid insulating member 32, the insulation performance of the conductive terminal 319 can be enhanced, thereby improving the safety of the motor 10.

[0262] In some embodiments, see Figure 32 and Figure 33 , Figure 32 For the Figure 31 The schematic structural diagram of the motor 10 of the conductive component 3 is shown. Figure 33 for Figure 32Schematic diagram of the middle NN end face. The rigid insulating member 32 and the conductive terminal 319 are both located within the first chamber 113. Insulating adhesive is encapsulated between the rigid insulating member 32 and the walls of the first chamber 113, and between the conductive terminal 319 and the walls of the first chamber 113. Sealing the rigid insulating member 32 and the walls of the first chamber 113, as well as between the conductive terminal 319 and the walls of the first chamber 113, with the insulating adhesive prevents foreign matter from entering the first chamber 113 and damaging the conductive member 31. The insulating adhesive forms a sealant 5.

[0263] Furthermore, the insulating glue can also fix the hard insulating member 32 and the conductive terminal 319 on the core shaft 11 , so as to ensure the stability of the hard insulating member and the conductive terminal 319 after being connected on the core shaft 11 .

[0264] In some examples, the height of the insulating adhesive potting along the axial direction of the core shaft is greater than the height of the conductive terminal 319. This allows the entire conductive terminal 319 to be sealed by the insulating adhesive, improving the sealing effect. Furthermore, the insulating adhesive can insulate the entire conductive terminal 319, preventing leakage of the conductive terminal 319 and improving the safety of the motor 10.

[0265] The outer periphery of the third conductive body 318 may be covered with an insulating layer to prevent the third conductive body 318 from leaking electricity and improve safety.

[0266] In other examples, the insulating adhesive fills the entire first cavity 113. This allows the insulating adhesive to not only seal and insulate the entire conductive terminal 319, but also the portion of the third conductive body 318 located within the first cavity 113, thereby further improving the sealing effect and safety of the conductive member 31. Furthermore, the insulating adhesive can bond the third conductive body 318 to the wall of the first cavity 113, thereby enhancing its stability.

[0267] In some embodiments, see Figure 34 , Figure 34 for Figure 31 The schematic diagram shows the structure of the conductive assembly 3 after removing the hard insulating member 32 and adding the external conductive member 33. The conductive assembly 3 also includes the external conductive member 33. One end of the external conductive member 33 is connected to the conductive terminal 319, and the other end of the external conductive member 33 is connected to the winding assembly 12. Specifically, the external conductive member 33 can be welded to the conductive terminal 319, and the other end of the external conductive member 33 can also be welded to the winding assembly 12.

[0268] Please continue reading Figure 31The outer circumference of the rigid insulating member 32 is further defined by a plurality of external through-holes 324, each of which communicates with a respective insulating hole 323. There are also multiple external conductive members 33, each of which is disposed within a respective external through-hole 324. Specifically, the external conductive member 33 passes through the external through-hole 324, such that one end of the external conductive member 33 extends into the insulating hole 323 and is electrically connected to the conductive terminal 319. The other end of each external conductive member 33 is electrically connected to a single-phase coil of the winding assembly 12.

[0269] For some examples, see Figure 32 The core shaft 11 is further provided with a plurality of third through holes 116 extending radially thereof. The plurality of third through holes 116 are all connected to the first chamber 113. Each third through hole 116 corresponds to an external through hole 324. An external conductive member 33 is provided through each third through hole 116.

[0270] In some embodiments, see Figure 35 , Figure 35 for Figure 33 Figure 3 is an enlarged schematic diagram of the structure at point P. The conductive assembly 3 also includes a housing 34. The housing 34 is connected to the end of the first chamber 113 facing away from the winding assembly 12. The conductive member 31 also includes a third conductive connector 31A. The third conductive connector 31A is connected to the end of the third conductive body 318 facing away from the conductive terminal 319. The third conductive connector 31A is snap-fitted to the housing 34, with a portion of the third conductive connector 31A exposed outside the housing 34, suitable for electrical connection to the motor controller.

[0271] The third conductive head 31A is fixed by the shell 34, and the shell 34 is connected to the end of the first chamber 113 facing away from the winding assembly 12, so that the shell 34 can fix and support the third conductive head 31A and fix the third conductive head 31A on the core shaft 11 to prevent the third conductive head 31A from shaking, thereby facilitating the sealing of the conductive part 31.

[0272] Furthermore, the housing 34 and the hard insulating member 32 can fix and support both ends of the conductive member 31 , thereby further reducing the shaking of the conductive member 31 and facilitating the sealing of the conductive member 31 .

[0273] In some examples, the housing 34 is snap-fitted onto the core shaft 11 .

[0274] In some embodiments, please refer to Figure 35, part of the shell 34 is located in the first chamber 113. The motor 10 also includes a sealing structure 8. The sealing structure 8 is arranged between the cavity wall of the first chamber 113 and the shell 34. The sealing structure 8 can seal the gap between the shell 34 and the cavity wall of the first chamber 113 to prevent external impurities from entering the first chamber 113 and causing damage to the conductive part 31. Among them, the sealing structure 8 can be a sealing ring. The number of sealing rings can be one or more. When the number of sealing rings is multiple, the multiple sealing rings are arranged at intervals along the axial direction of the core shaft 11.

[0275] In some examples, the housing 34 includes a second connecting portion 341 and a second clamping portion 342. The second connecting portion 341 is clamped to the core shaft 11. Specifically, a portion of the second connecting portion 341 extends into the first chamber 113, thereby clamping the second connecting portion 341 to the core shaft 11. The sealing structure 8 is disposed between the periphery of the first chamber 113 and the second connecting portion 341.

[0276] Exemplarily, the second connecting portion 341 includes an inner snap ring 3411 and an outer snap ring 3412. The inner snap ring 3411 is connected to the second clamping portion 342 and is located within the first chamber 113. The outer snap ring 3412 is connected to the second clamping portion 342, and is located outside the core shaft 11 and is disposed around the core shaft 11. In this way, the core shaft 11 is clamped and fixed by the inner snap ring 3411 and the outer snap ring 3412. When connecting the second connecting portion 341 to the core shaft 11, it is only necessary to buckle the second connecting portion 341 onto the core shaft 11, thereby facilitating the connection between the second connecting portion 341 and the core shaft 11.

[0277] The second cable-holding portion 342 is connected to the second connecting portion 341. Specifically, the second cable-holding portion 342 is located outside the first chamber 113. The second cable-holding portion 342 is provided with a second cable-holding hole. The third conductive head 31A is engaged with the second cable-holding hole, with a portion of the third conductive head 31A exposed from the second cable-holding portion 342, suitable for connection to the motor controller. This secures and supports the third conductive head 31A, reduces vibration of the conductive member 31, and facilitates sealing of the conductive member 31.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
