[0002] In related technologies, the suspension system includes a linear motor. The detection mechanism of the linear motor is used to detect the relative position of the stator assembly and the mover assembly. The detection mechanism has a connecting harness connected to the motor controller. The connecting harness needs to be led out from the air chamber of the suspension system, which results in poor air chamber sealing of the suspension system, affecting the working performance of the suspension system. Furthermore, the structure of leading the connecting harness out from the air chamber of the suspension system is complex, resulting in high manufacturing cost of the suspension system.

[0051] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0052] The following is for reference. Figures 1-7 This invention describes a motor 100 and a suspension system 200 according to an embodiment of the present invention. The motor 100 is a linear motor 100, or it can be a magnetic levitation motor 100. The suspension system 200 includes the motor 100 and an airbag mechanism 201. The airbag mechanism 201 and the motor 100 are assembled together to define an air chamber 202. At least a portion of the detection mechanism is located within the air chamber 202. That is, a portion of the structure of the detection mechanism is located within the air chamber 202, or the entire structure of the detection mechanism is located within the air chamber 202. The arrangement of the detection mechanism can be reasonably selected according to the actual usage, i.e., a portion of the structure of the detection mechanism is located within the air chamber 202, or the entire structure of the detection mechanism is located within the air chamber 202.

[0053] like Figures 1-7 As shown, according to an embodiment of the present invention, the motor 100 includes a stator assembly 10, a mover assembly 20, a detection mechanism, and a seal 40. The stator assembly 10 and the mover assembly 20 are fitted together and are movable relative to each other in a first direction. The detection mechanism is used to detect the relative position of the stator assembly 10 and the mover assembly 20 along the first direction. The detection mechanism has a connecting harness 31 suitable for connection to a motor controller. At least one of the stator assembly 10 and the mover assembly 20 has a harness through-hole 21, through which the connecting harness 31 passes. The seal 40 is used to seal the gap between the harness through-hole 21 and the connecting harness 31.

[0054] The motor 100 can be a linear motor 100, with a stator assembly 10 and a mover assembly 20 assembled together. The stator assembly 10 and the mover assembly 20 can be arranged along a first direction. When the motor 100... Figure 1 When placed in the center direction, the first direction is Figure 1The stator assembly 10 and the mover assembly 20 are movable relative to each other along the first direction, thereby changing the overall length of the motor 100. A detection mechanism is used to detect the relative position of the stator assembly 10 and the mover assembly 20 along the first direction. The detection mechanism can be a fiber optic sensor, displacement sensor, or other structure, as long as it can detect the relative position of the stator assembly 10 and the mover assembly 20 along the first direction. At least one of the stator assembly 10 and the mover assembly 20 has a wire harness through-hole 21. That is, either the stator assembly 10 or the mover assembly 20 has a wire harness through-hole 21, or both the stator assembly 10 and the mover assembly 20 have wire harness through-holes 21. The location of the wire harness through-hole 21 can be reasonably selected and arranged according to the actual usage. This application uses the mover assembly 20 having a wire harness through-hole 21 as an example for explanation.

[0055] The detection mechanism has a connecting harness 31, which can be a signal line. The connecting harness 31 is used to connect to the motor controller, thereby achieving communication between the detection mechanism and the motor controller. The detection mechanism outputs accurate displacement signals through the connecting harness 31 to achieve accurate control of the motor 100. The seal 40 can be made of rubber, foam, etc. The type of seal 40 can be reasonably selected according to the actual application, as long as the seal 40 has a sealing function. The seal 40 is used to seal the gap between the wiring harness through-hole 21 and the connecting harness 31. As an example, at least a portion of the seal 40 is assembled between the inner wall of the wiring harness through-hole 21 and the connecting harness 31, thereby sealing the gap between the wiring harness through-hole 21 and the connecting harness 31. As another example, the seal 40 is disposed outside the wire harness through hole 21 along the axial direction of the wire harness through hole 21. The seal 40 is assembled at the end position of the wire harness through hole 21, and the seal 40 covers the gap between the wire harness through hole 21 and the connecting wire harness 31, thereby sealing the gap between the wire harness through hole 21 and the connecting wire harness 31.

[0056] The connecting harness 31 is passed through the harness through hole 21, so that the connecting harness 31 in the air cavity 202 is led out through at least one of the stator assembly 10 and the mover assembly 20. This simplifies the structure for leading the connecting harness 31 out of the air cavity 202 of the suspension system 200. The connecting harness 31 is led out in a simple way, which is convenient for leading the connecting harness 31 out of the air cavity 202. This helps to reduce the manufacturing cost of the suspension system 200 and also helps to improve the production efficiency of the suspension system 200. Furthermore, by sealing the gap between the wire harness through-hole 21 and the connecting wire harness 31 by the sealing element 40, it is possible to effectively prevent the wire harness through-hole 21 from conducting through the air chamber 202 of the suspension system 200 and the external environment of the suspension system 200, which is beneficial to improving the sealing performance of the air chamber 202 of the suspension system 200, thereby improving the working performance of the suspension system 200. At the same time, the sealing method of the air chamber 202 implemented in this application is simple, which is beneficial to simplifying the structure of the motor 100 and the suspension system 200, and further reducing the manufacturing cost of the suspension system 200.

[0057] Therefore, by forming a wire harness through hole 21 in at least one of the stator assembly 10 and the mover assembly 20, and passing the connecting wire harness 31 through the wire harness through hole 21, and sealing the gap between the wire harness through hole 21 and the connecting wire harness 31 by the sealing member 40, when the motor 100 is installed in the suspension system 200, it is beneficial to improve the sealing performance of the air chamber 202 of the suspension system 200, thereby improving the working performance of the suspension system 200. Furthermore, the connecting wire harness 31 is easy to lead out from the air chamber 202 of the suspension system 200, and the structure is simple, which helps to reduce the manufacturing cost of the suspension system 200.

[0058] In some embodiments of this utility model, such as Figure 6 and Figure 7 As shown, at least one end of the wire harness through hole 21 is provided with a seal 40.

[0059] Along the axial direction of the wiring harness perforation 21, i.e., along the extension direction of the wiring harness perforation 21, both ends of the wiring harness perforation 21 are open, and the two ends of the wiring harness perforation 21 are respectively a first end and a second end. A sealing element 40 is provided at either the first end or the second end, or both the first end and the second end are provided with a sealing element 40. By providing the sealing element 40 at the end of the wiring harness perforation 21, the wiring harness perforation 21 can be sealed, reducing the risk of communication between the air chamber 202 of the suspension system 200 and the external environment of the suspension system 200. This improves the sealing performance of the air chamber 202 of the suspension system 200, thereby reducing the risk of external substances entering the air chamber 202 of the suspension system 200, maintaining the working performance of the suspension system 200, and extending the service life of the suspension system 200.

[0060] In some embodiments of this utility model, such as Figures 5-7 As shown, the seal 40 is annular and is arranged around the connecting wire harness 31 along the circumference of the wire harness through hole 21.

[0061] The sealing element 40 has an annular structure, a closed-loop structure, and a complete ring structure. The sealing element 40 defines a through-hole, through which the connecting wire harness 31 passes. This allows the sealing element 40 to be arranged circumferentially around the connecting wire harness 31 along the circumference of the wire harness through-hole 21. By setting the sealing element 40 as an annular structure, a gap seal between the wire harness through-hole 21 and the connecting wire harness 31 can be achieved along the entire circumference of the connecting wire harness 31, further improving the sealing performance of the air chamber 202 of the suspension system 200.

[0062] In some embodiments of this utility model, such as Figure 1 As shown, the mover assembly 20 has a wire harness through hole 21, and the wire harness through hole 21 extends through the mover assembly 20 along a first direction.

[0063] The mover assembly 20 has a wiring harness through-hole 21. Along the first direction, the air chamber 202 of the suspension system 200 is located on the side of the mover assembly 20 facing the stator assembly 10. The central axis of the wiring harness through-hole 21 can be parallel to the first direction. The wiring harness through-hole 21 is constructed as a straight hole, or it can extend obliquely along the first direction. The detection mechanism is located within the air chamber 202 of the suspension system 200. It passes through the mover assembly 20 along the first direction via the wiring harness through-hole 21, facilitating the insertion of the connecting wire harness 31 through the through-hole 21, thus ensuring a reasonable placement of the wiring harness through-hole 21.

[0064] In some embodiments of this utility model, such as Figure 1 As shown, the mover assembly 20 has a mover assembly housing 22, and the mover assembly housing 22 has a wire harness perforation 21 formed thereon.

[0065] The mover assembly housing 22 can be a metal part. The mover assembly housing 22 has good structural strength. Compared with the wire harness through hole 21 formed on other structural parts of the mover assembly 20, it can facilitate the processing of the wire harness through hole 21 on the mover assembly 20 while ensuring that the mover assembly 20 has sufficient structural strength. This can reduce the manufacturing difficulty of the mover assembly 20, thereby reducing the manufacturing cost of the motor 100 and improving the production efficiency of the motor 100. In addition, it can make the setting position of the wire harness through hole 21 more reasonable.

[0066] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the sidewall of the mover assembly housing 22 has a boss structure 23 protruding outward, and the wire harness through hole 21 is formed on the boss structure 23.

[0067] The boss structure 23 protrudes from the side wall of the mover assembly housing 22. The boss structure 23 can be annular, can be arranged around the circumference of the mover assembly housing 22, can be integrally formed with the mover assembly housing 22, or can be welded to the mover assembly housing 22. By forming the side wall of the mover assembly housing 22 with the outwardly protruding boss structure 23, the structural strength of the mover assembly housing 22 is improved. Furthermore, the wire harness through-hole 21 is formed in the boss structure 23, avoiding the problem of insufficient structural strength of the mover assembly housing 22 caused by the wire harness through-hole 21 being located in the main body of the mover assembly housing 22. While satisfying the requirement of placing the wire harness through-hole 21 in the mover assembly housing 22, it is beneficial to ensure that the mover assembly 20 has sufficient structural strength.

[0068] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the stator assembly 10 and the mover assembly 20 are arranged along a first direction, and a portion of the stator assembly 10 extends into the mover assembly 20. The detection mechanism is located at the end of the mover assembly 20 facing the stator assembly 10.

[0069] The stator assembly 10 and the mover assembly 20 are arranged along a first direction. The mover assembly housing 22 defines an accommodating space 26. The stator assembly 10 passes through the mover assembly housing 22. Part of the stator assembly 10 extends into the mover assembly 20, while another part of the stator assembly 10 is located outside the mover assembly 20. Figure 1 The air chamber 202 of the suspension system 200 is located on the side of the mover assembly 20 facing the stator assembly 10. Along the first direction, the detection mechanism is located at the end of the mover assembly 20 facing the stator assembly 10, which facilitates the installation of the detection mechanism. After the motor 100 and the airbag mechanism 201 are assembled, it is convenient to arrange the detection mechanism in the air chamber 202 of the suspension system 200.

[0070] In some embodiments of this utility model, such as Figure 1As shown, the stator assembly 10 may include a coil assembly 11, a spindle 12, a first buffer 13, and a second buffer 14. The coil assembly 11 is fixed to the spindle 12 by the first buffer 13 and the second buffer 14. The spindle 12 passes through the mover assembly housing 22. The coil assembly 11, the first buffer 13, and the second buffer 14 are located within the receiving space 26. The mover assembly 20 may also include a magnet assembly 27 and a guide rod 28. The magnet assembly 27 is disposed within the receiving space 26 and fixed to the side wall of the mover assembly housing 22. The magnet assembly 27 and the coil assembly 11 are opposite to and spaced apart. When the coil assembly 11 is energized, an air gap magnetic field is formed between the magnet assembly 27 and the coil assembly 11. The change in the air gap magnetic field generates an electromagnetic force that drives the mover assembly 20 to move relative to the stator assembly 10 along a first direction, thereby causing relative movement between the mover assembly 20 and the stator assembly 10. The end of the spindle 12 facing the mover assembly 20 forms a guide hole. The guide rod 28 is fixed to the mover assembly housing 22 and is assembled in the guide hole. The guide rod 28 is used to guide the mover assembly 20 and the stator assembly 10, so that the mover assembly 20 and the stator assembly 10 can move relative to each other in a first direction, thereby reducing the risk of the mover assembly 20 and the stator assembly 10 deviating.

[0071] In some embodiments of this utility model, such as Figure 1 As shown, the airbag mechanism 201 and the motor 100 are assembled together to define the air chamber 202. The airbag mechanism 201 may include a fixing structure 2011, an airbag 2012, and an airbag mechanism housing 2013. The motor 100... Figure 1 Taking the placement direction as an example, the upper part of the motor 100 is an air spring structure. The fixing structure 2011 is sleeved on the motor 100. The fixing structure 2011 is fixedly assembled with the spindle 12 of the stator assembly 10. The airbag 2012 is located below the fixing structure 2011 and is arranged around the mover assembly 20. The airbag mechanism housing 2013 is sleeved on the outside of the airbag 2012 and is arranged corresponding to the side wall of the mover assembly housing 22. The airbag 2012 is located between the mover assembly housing 22 and the airbag mechanism housing 2013. The inner side of the airbag 2012 is fixedly installed on the mover assembly housing 22. The upper end of the airbag 2012 is fixedly assembled with the fixing structure 2011. The fixing structure 2011, the spindle 12, the mover assembly housing 22 and the airbag 2012 together surround the air outlet cavity 202. The end of the airbag 2012 is open towards the air outlet cavity 202, so that the air outlet cavity 202 and the airbag 2012 are connected. The airbag 2012 can deform with the relative movement of the stator assembly 10 and the mover assembly 20.

[0072] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the detection mechanism includes a magnetic scale 32 and a sensing and reading device 33, also known as a reading head 33. One of the magnetic scale 32 and the sensing and reading device 33 is fixed to the stator assembly 10, and the other is fixed to the mover assembly 20. The magnetic scale 32 and the sensing and reading device 33 are arranged opposite to each other along a second direction. The sensing and reading device 33 is used to read the magnetic induction intensity of the magnetic scale 32. The sensing and reading device 33 is connected to the connecting wire harness 31. The first direction and the second direction intersect.

[0073] The detection mechanism is a magnetic induction sensor, which includes a magnetic scale 32 and a sensing and reading device 33. As an example, the magnetic scale 32 is fixed to the stator assembly 10, and the sensing and reading device 33 is fixed to the mover assembly 20. As another example, the magnetic scale 32 is fixed to the mover assembly 20, and the sensing and reading device 33 is fixed to the stator assembly 10. This application uses the example of the magnetic scale 32 being fixed to the stator assembly 10 and the sensing and reading device 33 being fixed to the mover assembly 20 for explanation. The magnetic scale 32 and the sensing and reading device 33 are arranged opposite each other along a second direction, and the first and second directions intersect. As an example, the first and second directions are perpendicular to each other. By arranging the magnetic scale 32 and the sensing and reading device 33 opposite each other along the second direction, the sensing and reading device 33 can read the change in magnetic induction intensity of the magnetic scale 32.

[0074] The sensing and reading device 33 can read the magnetic induction intensity (magnetic density) of the magnetic grating ruler 32. When the motor 100 outputs motion, that is, when the mover assembly 20 and the stator assembly 10 move relative to each other along the first direction, the spindle 12 moves relative to the mover assembly housing 22, so that the sensing and reading device 33 reads the magnetic induction intensity that changes with the axial movement. The changing magnetic density is converted into an electrical signal and transmitted to the motor controller. The motor controller analyzes the displacement information of the motor 100 and thus realizes accurate control of the motor 100.

[0075] The magnetic scale 32 includes a back iron 321 and a magnet assembly 322. The back iron 321 can be fixed to the spindle 12 of the stator assembly 10 and can extend along a first direction. The magnet assembly 322 is disposed on the surface of the back iron 321 facing the sensing and reading device 33. The magnet assembly 322 can be in two rows, with the two rows of magnet assemblies 322 embedded in the magnetic scale 32. Each row of magnet assemblies 322 consists of a periodic array of N-pole magnets 323 and S-pole magnets 324. The different periods of the two rows of magnet assemblies 322 can be used to calculate the absolute position. The sensing and reading device 33 can include a reading head body 333 and a reader. The reader can be a Hall chip or other magnetic sensing element used to read the magnetic induction intensity of the magnetic scale 32. The reader is fixed to the reading head body 333 and is connected to the connecting wire harness 31. The reader is used to read the magnetic flux density of the two columns of magnets 322. The follower assembly 20 and the stator assembly 10 move relative to each other in the first direction. The reader body 333 carries the reader and moves relative to the magnets 322 on the magnetic grating ruler 32. The reader reads two magnetic flux density signals that fluctuate sinusoidally with displacement.

[0076] In some embodiments of this utility model, such as Figure 1 , Figure 6 and Figure 7 As shown, the mover assembly 20 has a wire harness through hole 21, which extends through the mover assembly 20 in a first direction. The end of the mover assembly 20 facing the stator assembly 10 is provided with a sensing and reading device 33. A connecting wire harness 31 is led out from the end of the sensing and reading device 33 facing the mover assembly 20 so that the connecting wire harness 31 passes through the wire harness through hole 21.

[0077] The mover assembly housing 22 of the mover assembly 20 has a wire harness through-hole 21, which penetrates the mover assembly 20 along a first direction. The end of the mover assembly 20 facing the stator assembly 10 is... Figure 1 At the upper end of the mover assembly 20, the sensing and reading device 33 is fixedly mounted on the end of the mover assembly 20 facing the stator assembly 10. One end of the connecting harness 31 extends into the reader body 333 and is connected to the reader. Along the first direction, the connecting harness 31 extends out of the reader body 333 through the end of the sensing and reading device 33 facing the stator assembly 10. Figure 1 The lower end of the induction reading device 33. The connecting wire harness 31 is led out from the end of the induction reading device 33 facing the stator assembly 10, which facilitates the assembly of the connecting wire harness 31 into the wire harness through hole 21, thereby improving the assembly efficiency of the connecting wire harness 31 and reducing the setting length of the connecting wire harness 31, thus reducing the manufacturing cost of the motor 100.

[0078] In some embodiments of this utility model, such as Figure 2 and Figure 3As shown, the end of the sensor reading device 33 facing the mover assembly 20 has a through hole 331 opposite to the wire harness through hole 21, and the connecting wire harness 31 passes through the through hole 331. The through hole 331 on the end of the sensor reading device 33 facing the mover assembly 20 allows the connecting wire harness 31 to extend out of the reader body 333 from the through hole 331, achieving the effect of leading the connecting wire harness 31 out from the end of the sensor reading device 33 facing the mover assembly 20. Furthermore, along the first direction, the wire harness through hole 21 and the through hole 331 are arranged opposite to each other. The wire harness through hole 21 and the through hole 331 can be arranged directly opposite each other, which makes it easier to assemble the wire harness 31 into the wire harness through hole 21. This is more conducive to improving the assembly efficiency of the wire harness 31 and also to reducing the length of the wire harness 31, further reducing the manufacturing cost of the motor 100. At the same time, it also reduces the risk of the wire harness 31 accumulating in the air cavity 202.

[0079] In some embodiments of this utility model, such as Figure 1 , Figure 6 and Figure 7 As shown, a sealing element 40 is provided at the end of the wire harness through-hole 21 facing the sensing and reading device 33. For example... Figure 1 As shown, the end of the wiring harness through-hole 21 facing the sensing and reading device 33 is the upper end of the wiring harness through-hole 21. The sealing member 40 is annular, and the connecting wiring harness 31 can pass through the sealing member 40. The sealing member 40 can support the connecting wiring harness 31, reducing the risk of excessive movement at the connection point between the connecting wiring harness 31 and the reader, thereby ensuring a reliable connection between the connecting wiring harness 31 and the reader. Furthermore, the sealing member 40 seals the gap between the wiring harness through-hole 21 and the connecting wiring harness 31, effectively preventing the wiring harness through-hole 21 from conducting through the air chamber 202 of the suspension system 200 and the external environment of the suspension system 200. This is beneficial to improving the sealing performance of the air chamber 202 of the suspension system 200, thereby improving the working performance of the suspension system 200.

[0080] In some embodiments of this utility model, the sealing member 40 abuts against the sensing and reading device 33. The sensing and reading device 33 is fixed to the mover assembly 20, and at least a portion of the sealing member 40 can be located outside the wiring harness through-hole 21. The end of the sensing and reading device 33 facing the mover assembly 20 abuts against the sealing member 40. This abutment between the sensing and reading device 33 and the sealing member 40 allows the sealing member 40 to be securely installed at the end of the wiring harness through-hole 21 facing the sensing and reading device 33, reducing the risk of movement of the sealing member 40. It also allows the sealing member 40 to more reliably seal the gap between the wiring harness through-hole 21 and the connecting wiring harness 31, further improving the sealing performance of the air chamber 202 of the suspension system 200.

[0081] In some embodiments of this utility model, such as Figure 2 and Figure 3As shown, the sensing and reading device 33 has a first mounting hole 332, and the end face of the moving part assembly 20 facing the sensing and reading device 33 has a second mounting hole 24. The first mounting hole 332 and the second mounting hole 24 are arranged opposite to each other, and the sensing and reading device 33 is fixed to the moving part assembly 20 by a fixing connector provided in the first mounting hole 332 and the second mounting hole 24.

[0082] The reading head body 333 of the sensing and reading device 33 may have a first mounting hole 332, which can penetrate the reading head body 333 along a first direction. Along the first direction, the end face of the mover assembly 20 facing the sensing and reading device 33 has a second mounting hole 24, which can be formed in the mover assembly housing 22. The first mounting hole 332 and the second mounting hole 24 are arranged opposite to each other along the first direction. The number of first mounting holes 332 and second mounting holes 24 can be reasonably selected according to actual conditions. This application uses the example of having multiple first mounting holes 332 and multiple second mounting holes 24 for illustration, with each multiple first mounting hole 332 and multiple second mounting holes 24 corresponding one-to-one. As an example, there are two first mounting holes 332 and two mounting holes 24. As an example, the second mounting hole 24 is a threaded hole, and the fixing connector is a bolt. The bolt passes through the first mounting hole 332 and is installed in the threaded hole, thereby achieving the effect of fixing the sensing and reading device 33 to the mover assembly 20. As another example, the fixed connector is constructed as a fixing pin, which passes through the first mounting hole 332 and is mounted in the second mounting hole 24. The fixing pin is interference-fitted with both the sensing and reading device 33 and the moving part assembly 20, thereby achieving the effect of fixing the sensing and reading device 33 to the moving part assembly 20.

[0083] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the moving part assembly 20 has a mounting groove 25 formed on the end face facing the sensing and reading device 33. At least a portion of the sensing and reading device 33 is mounted in the mounting groove 25, and the wire harness through hole 21 extends to the bottom wall of the mounting groove 25.

[0084] Along the first direction, a mounting groove 25 is formed on the end face of the mover assembly 20 facing the sensor reading device 33. The mounting groove 25 can be formed in the mover assembly housing 22, and is recessed into the mover assembly housing 22. The reader head body 333 is assembled in the mounting groove 25, and part of the structure of the sensor reading device 33 is assembled in the mounting groove 25, or the entire sensor reading device 33 is assembled in the mounting groove 25. The shape and size of the mounting groove 25 are adapted to the shape and size of the sensor reading device 33. After the sensor reading device 33 is assembled in the mounting groove 25, the sidewall of the mounting groove 25 can limit the sensor reading device 33, which helps to improve the installation stability of the sensor reading device 33. Furthermore, as Figure 1As shown, the upper end of the wire harness through hole 21 extends to the bottom wall of the mounting groove 25. Since at least a portion of the sensing and reading device 33 is mounted in the mounting groove 25, the wire harness through hole 21 extends to the bottom wall of the mounting groove 25, achieving the effect of the wire harness through hole 21 being opposite to the sensing and reading device 33, which facilitates the installation of the connecting wire harness 31 in the wire harness through hole 21.

[0085] In some embodiments of this utility model, such as Figure 4 As shown, the connecting harness 31 may include at least two wire bodies 311, all of which extend along the length direction of the connecting harness 31, and the external connection ends 312 of the at least two wire bodies 311 are spaced apart along the length direction of the connecting harness 31, and the external connection ends 312 are adapted to be connected to the motor controller.

[0086] The connecting harness 31 may include at least two wires 311. The number of wires 311 can be two, three, four, five, six, etc., and the number can be selected appropriately based on actual needs. Each wire 311 has an external connection end 312 at its end facing away from the sensing and reading device 33. The external connection end 312 can be either a male or female plug. The external connection end 312 connects to the motor controller and can be plugged into the motor controller to achieve communication between the sensing and reading device 33 and the motor controller. By providing an external connection end 312 at the end of each wire 311 facing away from the sensing and reading device 33, the assembly process for the external connection end 312 can be reduced.

[0087] If the external connection ends 312 of multiple wire bodies 311 are located at the same position along the length of the connecting wire harness 31, resulting in a large cross-sectional area at the maximum cross-sectional area of ​​the connecting wire harness 31, a wire harness through-hole 21 with a larger cross-sectional size is required for the connecting wire harness 31 to pass through the wire harness through-hole 21. However, in order to ensure that the air cavity 202 meets the sealing requirements and that the mover assembly housing 22 meets the structural strength requirements, the cross-sectional size of the wire harness through-hole 21 should be as small as possible. In this application, by arranging the external connection ends 312 of at least two wire bodies 311 spaced apart along the length of the connecting wire harness 31, it is beneficial to reduce the maximum cross-sectional area of ​​the connecting wire harness 31. A wire harness through-hole 21 with a smaller cross-sectional size can meet the requirements for the connecting wire harness 31 to pass through, which is beneficial to achieving the sealing requirements of the air cavity 202 and also beneficial to achieving the structural strength requirements of the mover assembly housing 22.

[0088] In some embodiments of this utility model, such as Figure 4 As shown, along the length of the connecting harness 31, the external connection end 312 of part of the wire 311 is located at the first position of the connecting harness 31, and the external connection end 312 of another part of the wire 311 is located at the second position of the connecting harness 31.

[0089] In this configuration, along the length of the connecting harness 31, the external connection ends 312 of a portion of the wires 311 are located at a first position, while the external connection ends 312 of another portion of the wires 311 are located at a second position. The first and second positions are different locations spaced apart along the length of the connecting harness 31. Taking six wires 311 as an example, the external connection ends 312 of three wires 311 are located at the first position, and the external connection ends 312 of the other three wires 311 are located at the second position. This design helps reduce the maximum cross-sectional area of ​​the connecting harness 31, allowing the wires to be inserted through holes 21 with smaller cross-sectional dimensions. This also helps achieve the sealing requirements of the air cavity 202 and meets the structural strength requirements of the mover assembly housing 22.

[0090] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the connecting harness 31 may further include a sheath 60, which covers the exterior of the plurality of wires 311 and covers the end of the wire 311 that is connected to the reader. The sheath 60 is an insulating component. When a sealing component 40 is provided at the end of the harness through hole 21 facing the sensing reading device 33, the sheath 60 can be inserted through the sealing component 40, thereby sealing the air cavity 202 and facilitating the connection harness 31 to pass through the harness through hole 21.

[0091] In some embodiments of this utility model, such as Figure 4 As shown, each wire body 311 can be fitted with a wire plug 313. The wire plug 313 can be arranged adjacent to the corresponding external connection end 312. The motor controller has a plug hole. When the external connection end 312 is inserted into the plug hole, the wire plug 313 can seal the plug hole on the motor controller, thereby sealing the plug hole.

[0092] In some embodiments of this utility model, such as Figure 4 and 5 As shown, the motor 100 may further include a protective sleeve 50, which can be fitted over the outside of multiple wire bodies 311. The protective sleeve 50 can be connected to and bonded to the covering sleeve 60. During the process of the connecting wire harness 31 passing through the wire harness through hole 21, the protective sleeve 50 can reduce the risk of damage to the external connection end 312 and the wire plug 313, and also facilitate the passing of the connecting wire harness 31 through the wire harness through hole 21. After the connecting wire harness 31 passes through the wire harness through hole 21, the protective sleeve 50 can be removed.

[0093] like Figure 1 As shown, the suspension system 200 according to an embodiment of the present utility model includes: a motor 100, wherein the motor 100 is the motor 100 of the above embodiment.

[0094] According to the suspension system 200 of this utility model embodiment, the connecting wire harness 31 is passed through the wire harness through hole 21, so that the connecting wire harness 31 in the air cavity 202 is led out through at least one of the stator assembly 10 and the mover assembly 20. This simplifies the structure for leading the connecting wire harness 31 out of the air cavity 202 of the suspension system 200. The method of leading out the connecting wire harness 31 is simple and convenient for leading out the connecting wire harness 31 in the air cavity 202. This is beneficial to reducing the manufacturing cost of the suspension system 200 and also to improving the production efficiency of the suspension system 200. Furthermore, by sealing the gap between the wire harness through-hole 21 and the connecting wire harness 31 by the sealing element 40, it is possible to effectively prevent the wire harness through-hole 21 from conducting through the air chamber 202 of the suspension system 200 and the external environment of the suspension system 200, which is beneficial to improving the sealing performance of the air chamber 202 of the suspension system 200, thereby improving the working performance of the suspension system 200. At the same time, the sealing method of the air chamber 202 implemented in this application is simple, which is beneficial to simplifying the structure of the motor 100 and the suspension system 200, and further reducing the manufacturing cost of the suspension system 200.

[0095] In some embodiments of this utility model, such as Figure 1 As shown, the suspension system 200 also includes an airbag mechanism 201. The airbag mechanism 201 and the motor 100 are assembled together to define an air chamber 202, and at least a portion of the detection mechanism is located within the air chamber 202, thereby facilitating the installation of the detection mechanism.

[0096] In some embodiments of this utility model, such as Figure 1 As shown, the airbag mechanism 201 includes an airbag 2012, which is connected to the air chamber 202 and is attached to the outer wall of the wire harness perforation 21.

[0097] The design incorporates wiring harness perforations 21 on at least one of the stator assembly 10 and the mover assembly 20. Taking the mover assembly 20 as an example, when the mover assembly housing 22 has the wiring harness perforation 21, the outer wall of the mover assembly housing 22 serves as the outer wall of the wiring harness perforation 21, and the airbag 2012 is in contact with the mover assembly housing 22. The wiring harness perforation 21 on the mover assembly housing 22 avoids the airbag skin of the airbag 2012, preventing the airbag skin from being unable to fully fit the groove due to the groove on the outer wall of the mover assembly housing 22, thus reducing the risk of damage to the airbag skin of the airbag 2012.

[0098] In some embodiments of this utility model, such as Figure 1As shown, the airbag mechanism 201 and the motor 100 are assembled together to define the air chamber 202. The airbag mechanism 201 may include a fixing structure 2011, an airbag 2012, and an airbag mechanism housing 2013. The motor 100... Figure 1 Taking the placement direction as an example, the upper part of the motor 100 is an air spring structure. The fixing structure 2011 is sleeved on the motor 100. The fixing structure 2011 is fixedly assembled with the spindle 12 of the stator assembly 10. The airbag 2012 is located below the fixing structure 2011 and is arranged around the mover assembly 20. The airbag mechanism housing 2013 is sleeved on the outside of the airbag 2012 and is arranged corresponding to the side wall of the mover assembly housing 22. The airbag 2012 is located in the mover assembly housing 22. Between the stator assembly 10 and the airbag housing 2013, the inner side of the airbag 2012 is fixed to the mover assembly housing 22 and fits against the outer wall of the mover assembly housing 22. The upper end of the airbag 2012 can be fixedly assembled with the fixed structure 2011. The fixed structure 2011, the spindle 12, the mover assembly housing 22, and the airbag 2012 together surround the air outlet cavity 202. The end of the airbag 2012 facing the air cavity 202 is open, thereby connecting the air cavity 202 and the airbag 2012. The airbag 2012 can deform with the relative movement of the stator assembly 10 and the mover assembly 20.

[0099] The vehicle according to the present invention includes the suspension system 200 of the above embodiment, which is beneficial to reducing the vehicle's manufacturing cost, improving the vehicle's ride comfort, and also improving the vehicle's driving performance.

[0100] When the suspension system 200 is installed on a vehicle, the mover assembly housing 22 can be fixedly connected to the vehicle's structural components, and at least one of the spindle 12 and the fixing structure 2011 is fixedly connected to the vehicle's structural components.

[0101] Other configurations and operations of the motor 100 and suspension system 200 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
