[0002] The conveying system includes a stator module and a mover module, which are magnetically coupled to drive the mover module. In related technologies, the stator module includes a stator body and stator windings. The stator windings are usually fixed to the surface of the stator body by screwing, which increases the width of the stator module and results in a larger footprint. Utility Model Content

[0003] This application provides a conveying system designed to address the issue of stator modules occupying a large area.

[0004] This application provides a conveying system, which includes a stator module and a mover module magnetically coupled to the stator module. The stator module includes a stator base and a stator assembly. The stator base has a top guide rail wall, a first side wall, and a second side wall. The first side wall and the second side wall are both disposed opposite to the top guide rail wall and along the width direction of the stator base. The first side wall is recessed towards the second side wall to form a mounting groove, and the mounting groove extends upward through the top of the first side wall, or the mounting groove extends upward through the top of the first side wall and the top guide rail wall. The stator assembly includes a stator core and a stator winding wound on the stator core. The stator core and the stator winding are both located within the mounting groove.

[0005] In some embodiments, the top surface of the stator assembly is flush with the top guide rail wall along the vertical direction of the stator base.

[0006] In some embodiments, the stator core has a through hole, and the stator module further includes a screw connector that passes through the through hole and is screwed to the bottom wall of the mounting groove to fix the stator core to the bottom wall of the mounting groove.

[0007] In some embodiments, there are multiple stator assemblies, which are spliced ​​together and fixedly disposed on the same stator base. The stator conveyor line is used to drive and guide the movement of the mover module. The stator module also includes a first guide rail, which is disposed on the top guide rail wall and extends along the conveying direction of the stator conveyor line. The mover module includes a slider, which slides in cooperation with the first guide rail.

[0008] In some embodiments, the stator module further includes a second guide rail disposed on the first sidewall and located below the mounting groove, and extending along the conveying direction; the mover module further includes a roller that rolls in cooperation with the second guide rail.

[0009] In some embodiments, the stator module further includes a blocking member detachably disposed on the top guide rail wall and / or the first side wall, adjacent to the first guide rail or the second guide rail, and located at the end and / or beginning of the stator conveying line along the conveying direction.

[0010] In some embodiments, along the width direction, the width of the stator assembly is less than or equal to the overall width of the mounting slot and the second guide rail.

[0011] In some embodiments, the stator module further includes a sensor array component disposed on the second sidewall, and the mover module includes a mover base and a sensing component. The mover base is slidably connected to the stator base, and the sensing component is disposed on the mover base. The sensing component and the sensor array component are opposite to and spaced apart in the width direction.

[0012] In some embodiments, in the direction from the top to the bottom of the stator base, the second sidewall includes a second receiving cavity and a first receiving cavity arranged sequentially, the sensor array component is disposed in the second receiving cavity, wherein the stator module further includes a connector, the connector is at least partially disposed in the first receiving cavity, and along the width direction, the depth of the first receiving cavity is greater than the depth of the second receiving cavity.

[0013] In some embodiments, the conveying system further includes bridging components, and the number of stator modules is multiple. Each stator module further includes bridging slots, which are disposed at both ends of the top of the top guide wall or the second side wall along the length direction. The two ends of the bridging component are respectively disposed in two bridging slots of different stator modules to connect adjacent stator modules through the bridging component.

[0014] This embodiment of the application provides a mounting groove on the first sidewall, with both the stator core and stator windings located within the mounting groove. This avoids the increased volume of the stator module caused by the outward protrusion of the stator assembly, thereby reducing the footprint of the stator module. Furthermore, the laminated structure of the stator core reduces magnetic field diffusion, resulting in a more uniform and stable air gap magnetic field distribution and reduced susceptibility to external environmental interference, thus enhancing magnetic field stability. The stator core can transform a disordered magnetic field into a highly efficient directional magnetic circuit, increasing thrust and enabling rapid control of the start-up or shutdown of the mover module. Moreover, compared to stator assemblies without a stator core, the stator assembly of this embodiment includes a stator core, which is typically made of standardized laminated silicon steel sheets. The stator windings can be wound onto the stator core using automated equipment. Silicon steel sheets are common industrial materials, and their cost is lower than that of special materials such as epoxy resin required without a stator core, thus reducing manufacturing costs.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Please see Figures 1-3 This application provides a conveying system 100, which is an integrated system that uses mechanical, electrical, and automated control technologies to transfer materials from one spatial location to another.

[0020] The conveying system 100 includes a stator module 10 and a mover module 20.

[0021] Specifically, there are multiple stator modules 10, which are spliced ​​together to form a stator conveyor line. The stator conveyor line is used to drive and guide the movement of the mover module 20. That is, the mover module 20 can move along the conveying direction of the stator conveyor line. The stator conveyor line formed by splicing multiple stator modules 10 can be a straight stator conveyor line, an arc stator conveyor line, or a loop stator conveyor line. This application embodiment does not specifically limit this.

[0022] Furthermore, this application embodiment does not specifically limit the way stator modules 10 are spliced ​​together. For example, along the conveying direction, each end of the stator module 10 along its length is provided with a bridging slot 50, that is, each stator module 10 has at least two bridging slots 50. The conveying system 100 also includes a bridging component, with both ends of the bridging component respectively disposed in the two bridging slots 50 of different stator modules 10, so as to connect adjacent stator modules 10 through the bridging component. It can be understood that multiple stator modules 10 can be spliced ​​together by bridging components. That is, one end of the bridging component is installed in one of the bridging slots 50 and can be installed on one of the stator modules 10 by screws, and the other end of the bridging component is installed in the bridging slot 50 of another stator module 10 and can be installed on another stator module 10 by screws, thereby realizing the connection between adjacent stator modules 10. Since adjacent stator modules 10 are connected by bridging components, the convenience of installation between stator modules 10 is improved.

[0023] Furthermore, the bridging groove 50 is formed on the top guide rail wall 111 of the stator base 11, the bridging component is installed in the bridging groove 50, and the bridging component is locked to the stator base 11 by screws. In this way, the installation accuracy between the stator modules 10 is improved.

[0024] It should be noted that the embodiments of this application do not specifically limit the shape of the bridging groove 50 or the shape of the bridging component, but the bridging component needs to be installed in the bridging groove 50. For example, the shape of the bridging groove 50 can be rectangular or square.

[0025] Please continue reading. Figures 1-3 The mover module 20 includes a mover base 21 and a permanent magnet 22. The mover base 21 is slidably connected to the stator module 10, and the permanent magnet 22 is disposed on the mover base 21 and magnetically coupled to the stator module 10. It can be understood that the mover base 21 has a bearing surface capable of supporting the material to be conveyed. Under the influence of the magnetic field generated by the stator module 10, the permanent magnet 22 on the mover base 21 is pushed by electromagnetic force, thereby driving the mover base 21 and the material mounted on the bearing surface to move together, realizing the conveying of the material along the conveying direction of the stator conveyor line.

[0026] The stator module 10 will be described in detail below.

[0027] Please continue reading. Figures 1-3 The stator module 10 includes a stator base 11 and a stator assembly 12.

[0028] The stator base 11 has a top guide rail wall 111, a first side wall 112, and a second side wall 113. The first side wall 112 and the second side wall 113 are both connected to the top guide rail wall 111, and the first side wall 112 and the second side wall 113 are arranged opposite to each other along the width direction of the stator base 11. That is, the top guide rail wall 111 is connected to the first side wall 112 and the second side wall 113 on both sides in the width direction, and the first side wall 112 is recessed towards the second side wall 113 to form a mounting groove 112A. The mounting groove 112A extends upward to the top of the first side wall 112, or the mounting groove 112A extends upward to the top of the first side wall 112 and the top guide rail wall 111.

[0029] The top guide rail wall 111, the first side wall 112, and the second side wall 113 can be integral components to reduce assembly steps; alternatively, the top guide rail wall 111, the first side wall 112, and the second side wall 113 can be spliced ​​together to form the stator base 11. Furthermore, the stator base 11 formed by the top guide rail wall 111, the first side wall 112, and the second side wall 113 has an internal accommodating cavity. This cavity can be used to accommodate electronic components such as the circuit board 60 and a fan, facilitating the control of the stator winding's on / off state or heat dissipation for the stator winding.

[0030] The stator assembly 12 includes a stator core and stator windings, with the stator windings wound around the stator core. It is understood that both the stator core and stator windings are located within the mounting slot 112A. This avoids the stator module 10 from protruding outwards, thus reducing its footprint and making it suitable for applications with strict space requirements. Furthermore, since both the stator core and stator windings are located within the mounting slot 112A, the mounting slot 112A provides physical protection for the stator core and stator windings, reducing damage from external dust, oil, or impacts to the stator assembly 12 and extending its service life. The stator core and stator windings are also less prone to displacement, ensuring stable electromagnetic performance. Multiple stator assemblies 12 are connected and fixedly mounted on the same stator base 11; that is, multiple stator assemblies 12 can be mounted on a single stator base 11.

[0031] The stator core and stator windings are the core functional components of electromagnetic drives. The stator core is made of a high-permeability material, which significantly enhances the magnetic field strength. Furthermore, the stator core is typically made of low-loss silicon steel sheets, reducing eddy current losses and hysteresis losses. In addition, the stator core is also a highly efficient heat dissipation carrier; that is, the stator core is usually made of low-loss silicon steel sheets, which have excellent thermal conductivity, allowing the heat generated by the stator windings to be quickly transferred through the stator core to the external heat sink, effectively improving heat dissipation.

[0032] It should be noted that the structure of the mounting groove 112A in this embodiment can be formed in two ways. In the first way, the first sidewall 112 and the second sidewall 113 are arranged opposite to each other in the width direction and connected by the top guide wall 111. The tops of both the first sidewall 112 and the second sidewall 113 are parallel to the top of the top guide wall 111. In this case, the mounting groove 112A is formed on the first sidewall 112 and extends upwards to the top of the first sidewall 112. In the second way, both the first sidewall 112 and the second sidewall 113 are connected to the top guide wall 111 and are located below the top guide wall 111, arranged opposite to each other in the width direction. In this case, the mounting groove 112A extends upwards sequentially through the top of the first sidewall 112 and the top guide wall 111.

[0033] When the structure of the mounting groove 112A is formed in the first manner, the bridging groove 50 is provided on the top of the second side wall 113; when the structure of the mounting groove 112A is formed in the second manner, the bridging groove 50 is provided on the top guide rail wall 111 and is spaced apart from the mounting groove 112A in the width direction.

[0034] This embodiment of the application provides a mounting groove 112A on the first sidewall 112, with both the stator core and stator windings located within the mounting groove 112A. This avoids the increased volume of the stator module 10 caused by the outward protrusion of the stator assembly 12, thereby reducing the footprint of the stator module 10. Furthermore, the laminated structure of the stator core reduces magnetic field diffusion, resulting in a more uniform and stable air gap magnetic field distribution and reduced interference from the external environment, thus enhancing magnetic field stability. The stator core can transform a disordered magnetic field into a highly efficient directional magnetic circuit, increasing thrust and enabling rapid control of the start-up or shutdown of the mover module 20. Moreover, compared to a stator assembly 12 without a stator core, the stator assembly 12 of this embodiment includes a stator core, which is typically made of standardized silicon steel sheets laminated together. The stator windings can be wound onto the stator core using automated equipment. Silicon steel sheets are common industrial materials, and their cost is lower than that of special materials such as epoxy resin required without a stator core, thus reducing manufacturing costs.

[0035] It should be noted that the stator base 11 and the mover base 21 are usually made of materials with good rigidity and strength so that the stator base 11 and the mover base 21 are not easily bent or broken under external force, such as steel, aluminum alloy, etc. This application embodiment does not make specific limitations in this regard.

[0036] Please continue reading. Figures 1-3 The stator module 10 also includes a sensor array component 17, which is disposed on the second side wall 113; the mover module 20 also includes a sensing component 25, which is disposed on the mover base 21 and is disposed opposite to the sensor array component 17. In the width direction, the sensing component 25 and the sensor array component 17 are spaced apart, so that the sensor array component 17 can read the signal generated by the sensing component 25 at all times to obtain the movement position of the mover module 20.

[0037] The sensing component 25 and the sensor array component 17 are spaced apart, meaning there is a non-contact signal connection between them. The sensing component 25 can send signals to the sensor array component 17. This embodiment does not specifically limit the types of the sensing component 25 and the sensor array component 17. For example, the sensor array component 17 may include an optical encoder array or a magnetic encoder array, and the sensing component 25 may include a magnetic encoder or an optical encoder. By reading the signals emitted by the sensing component 25 through the sensor array component 17, the position of the stator base 21 is determined, and the corresponding stator winding is controlled to periodically energize. Furthermore, since the sensor array component 17 is located on the second sidewall 113 and the stator assembly 12 is located on the first sidewall 112, the height of the stator base 11 can be effectively reduced in the vertical direction.

[0038] Please see Figure 2Furthermore, in the direction from the top to the bottom of the stator base 11, the second sidewall 113 includes a second receiving cavity 1131 and a first receiving cavity 114 arranged sequentially. The sensor array component 17 is disposed in the second receiving cavity 1131, and the sensor array component 17 is spaced apart from the sensing component 25. The stator assembly 12 is disposed on the mounting groove 112A opened in the first sidewall 112. That is, in the width direction of the stator base 11, the sensor array component 17 and the stator assembly 12 are arranged opposite to each other. In this way, the silicon steel sheet in the stator assembly 12 is avoided from affecting the detection accuracy of the sensing component 25.

[0039] Please see Figures 1-2 The stator base 21 includes a support plate 211, which has a support surface for supporting the material to be conveyed. In the width direction, the sensing component 25 and the permanent magnet 22 are located on both sides of the stator base 11, and the sensor array component 17 is disposed in the second receiving cavity 1131 opened in the second side wall 113. The sensor array component 17 and the sensing component 25 are spaced apart. The stator assembly 12 is disposed on the mounting groove 112A opened in the first side wall 112 and is magnetically coupled to the permanent magnet 22. This design avoids mutual interference between the permanent magnet 22 and the sensor array component 17.

[0040] In some embodiments, the first sidewall 112 is recessed toward the second sidewall 113 to form a mounting groove 112A. It is understood that the mounting groove 112A is an inward recess of the first sidewall 112 toward the second sidewall 113, preserving the complete structure of the second sidewall 113. This satisfies the assembly requirements of the stator assembly 12 while maintaining the overall structural strength of the stator module 10. Furthermore, the mounting groove 112A extends upward to the top guide rail wall 111, forming a top-open groove structure. This facilitates the assembly of the stator assembly 12 into the mounting groove 112A. Additionally, when the permanent magnet 22 of the mover module 20 is magnetically coupled to the stator winding, heat is generated in the stator winding. This heat is dissipated through the mounting groove 112A extending upward to the top guide rail wall 111, thus cooling the stator winding.

[0041] Please see Figure 3 Furthermore, in some embodiments, the top surface of the stator assembly 12 is flush with the top guide rail wall 111 along the vertical direction of the stator base 11, thereby preventing the stator assembly 12 from protruding outward from the top guide rail wall 111, which would increase the overall height of the stator module 10.

[0042] In some embodiments, the stator core has a through hole, and the stator module 10 further includes a screw connector. The screw connector passes through the through hole and is screwed into the bottom wall of the mounting groove 112A. That is, after the screw connector passes through the through hole of the stator core, it engages with the threaded hole on the bottom wall of the mounting groove 112A to fix the stator core to the bottom wall of the mounting groove 112A. The stator core and the stator base 11 can be independently processed and then quickly assembled by the screw connector to shorten the production cycle.

[0043] Please see Figures 1-2 In some embodiments, the stator module 10 further includes a first guide rail 15, which is disposed on the top guide rail wall 111 and extends along the conveying direction; that is, the first guide rail 15 can be connected to the top guide rail wall 111 by means of screwing, welding, bonding or snapping to fix the first guide rail 15 on the stator base 11; or, the first guide rail 15 can also be fixed to the stator base 11 by integral injection molding to reduce assembly steps.

[0044] The mover base 21 includes a slider 23, which slides in conjunction with the first guide rail 15. This allows the mover module 20 to slide on the first guide rail 15, enabling it to move along the conveying direction. Furthermore, the first guide rail 15 provides a limit to the conveying direction to prevent the mover module 20 from derailing, and it also provides support for the mover module 20.

[0045] Since there can be multiple stator modules 10, the first guide rail 15 can span multiple stator modules 10 and connect to the bridging slots 50 of different stator modules 10 at both ends in conjunction with the bridging component. In this way, the first guide rail 15 and the bridging component together improve the installation accuracy between stator modules 10.

[0046] It should be noted that the embodiments of this application do not specifically limit the types of the first guide rail 15 and the slider 23.

[0047] For example, the first guide rail 15 can be a linear track, and the slider 23 is a slider. The linear track and the slider slide together, and the linear track usually adopts a U-shaped groove design. In this way, the contact surface between the slider and the linear track is large, the sliding fit accuracy is high, thereby improving the driving accuracy of the mover module 20.

[0048] For example, the first guide rail 15 can be a V-shaped rail, and the slider 23 can be a roller. When the V-shaped rail and the roller are in contact, the extension direction of the V-shaped rail can be changed, thereby changing the conveying direction of the mover module 20 so as to adapt to stator modules 10 of different shapes.

[0049] Please see Figure 1 as well as Figure 3Furthermore, in some embodiments, the stator module 10 further includes a second guide rail 16, which is disposed on the first sidewall 112 and located below the mounting groove 112A, and extends along the conveying direction. That is, the second guide rail 16 can be connected to the first sidewall 112 by means of screwing, welding, bonding, or snap-fitting to fix the second guide rail 16 to the stator base 11; or, the second guide rail 16 can also be fixed to the stator base 11 by integral injection molding to reduce assembly steps. The mover base 21 also includes a roller 24, which rolls with the second guide rail 16. In this way, when the first guide rail 15 is in sliding engagement with the slider 23, the rolling engagement of the second guide rail 16 with the roller 24 increases the stability of the mover module 20 on the stator conveying line and reduces the vibration between the mover module 20 and the stator module 10, thereby reducing the noise generated by the conveying system 100. The second guide rail 16 is located below the mounting groove 112A, so that when the stator winding is magnetically coupled to the permanent magnet 22, it will not interfere with the rolling engagement of the second guide rail 16 and the roller 24.

[0050] The second guide rail 16 and the roller 24 roll together, which can reduce the friction between the stator module 10 and the mover module 20, thereby extending the service life of the conveying system 100; at the same time, it reduces energy loss and is more adaptable to high-speed operation.

[0051] Furthermore, the second guide rail 16 can be a portion of the first sidewall 112, meaning the first sidewall 112 can be formed into the second guide rail 16. Thus, by providing rollers 24 on the mover module 20, the rollers 24 roll in contact with the second guide rail 16 formed by the first sidewall 112, enabling the mover module 20 to slide on the first sidewall 112 of the stator base 11. This saves costs and improves space utilization. Of course, in other embodiments, the second guide rail 16 is provided on the first sidewall 112. The second guide rail 16 can be connected to the first sidewall by welding, screwing, bonding, or other methods to reduce the friction between the second guide rail 16 and the rollers 24, extending the service life of the conveying system 100.

[0052] Please see Figure 3 In some embodiments, along the width direction, the width of the stator assembly 12 is less than or equal to the overall width of the mounting groove 112A and the second guide rail 16; thus, the stator assembly 12 will not protrude outward to the outer surface of the second guide rail 16 in the width direction, thereby avoiding an excessively wide stator module 10; and based on the above embodiments, along the vertical direction of the stator base 11, the top surface of the stator assembly 12 is flush with the top guide rail wall 111, thus making the overall structure of the stator module 10 more compact, thereby ensuring that the stator module 10 can adapt to different application scenarios and improve the space utilization of the conveying system 100.

[0053] In the vertical direction, the height of the stator assembly 12 is greater than the height of the second guide rail 16. Thus, with the width of the stator assembly fixed, since the width of the stator assembly 12 is less than or equal to the overall width of the mounting groove 112A and the second guide rail 16, and the stator assembly 12 and the permanent magnet 22 are spaced apart, the distance between the second guide rail 16 and the mover base 21 is increased in the width direction. This provides a larger installation space for the roller 24, which is beneficial for the roller 24 to be installed on the mover base 21 and for improving space utilization.

[0054] Please see Figures 1-3 In some embodiments, the stator module 10 further includes a blocking member 18, which is disposed on at least one of the top guide rail wall 111 and the first side wall 112. That is, the blocking member 18 may be disposed on the top guide rail wall 111, or the blocking member 18 may be disposed on the first side wall 112, or the blocking member 18 may be disposed on both the top guide rail wall 111 and the first side wall 112. The blocking member 18 is disposed adjacent to the first guide rail 15 or the second guide rail 16, and along the conveying direction, the blocking member 18 is located on at least one of the end and the beginning of the stator conveying line. It is understandable that during the process of magnetic coupling between the stator winding and the permanent magnet 22 of the mover module 20 to drive the mover module 20 to move along the conveying direction of the stator conveyor line, the mover module 20 is prone to derailment at the end or beginning of the stator conveyor line in an uncontrolled state. Therefore, by providing a blocking member 18 on at least one of the top guide rail wall 111 and the first side wall 112, and the blocking member 18 is located at at least one of the end or beginning of the stator conveyor line, the mover module 20 is prevented from derailing in an uncontrolled state, so as to ensure the safety of the conveying system 100.

[0055] Furthermore, the blocking member 18 is detachably disposed on at least one of the top guide rail wall 111 and the first side wall 112. For example, when the blocking member 18 is detachably disposed on the top guide rail wall 111 and the blocking member 18 is located at the end and the beginning of the stator conveying section along the conveying direction, the blocking member 18 is usually detachably disposed on the top guide rail wall 111 so that the mover module 20 can be disengaged from the first guide rail 15, thereby facilitating the maintenance of the mover module 20.

[0056] It should be noted that the present application does not specifically limit the connection method between the blocking member 18 and the top guide rail wall 111 or the first side wall 112. For example, the blocking member 18 can be fixed to the top guide rail wall 111 or the first side wall 112 by means of screwing, snap-fitting or magnetic attraction.

[0057] Please see Figure 3In some embodiments, the second sidewall 113 has a first receiving cavity 114, and the opening 115 of the first receiving cavity 114 is disposed away from the first sidewall 112; that is, the opening 115 of the first receiving cavity 114 is disposed opposite to the slot of the mounting groove 112A. In this way, the opening 115 of the first receiving cavity 114 can be avoided from interfering with the movement of the moving module 20, and the first receiving cavity 114 is disposed below the sensor array component 17.

[0058] The stator module 10 also includes a connector and a cover plate 13. The connector is at least partially disposed within the first receiving cavity 114, and the cover plate 13 covers the opening 115. That is, the connector is disposed within the first receiving cavity 114 to reduce damage to the connector and extend its service life. Furthermore, this application embodiment does not specifically limit the material of the cover plate 13. For example, the cover plate 13 can be made of plastic, metal, or composite materials. When the cover plate 13 is made of metal, it can improve electromagnetic shielding to suppress interference from external electromagnetic fields on the connector.

[0059] Please see Figure 2 Furthermore, in the direction from the top to the bottom of the stator base 11, the second sidewall 113 includes a second receiving cavity 1131 and a first receiving cavity 114 arranged sequentially. The sensor array component 17 is disposed in the second receiving cavity 1131 and close to the top guide rail wall 111. A circuit integrated board 60 is disposed in the receiving cavity inside the stator base 11, and the circuit integrated board 60 has a connector. The connector is at least partially disposed in the first receiving cavity 114. In this way, the first receiving cavity 114 can be used for clustering to avoid the cables connected to the connector being too messy, thereby affecting signal transmission.

[0060] Furthermore, in the width direction, the depth of the first receiving cavity 114 is greater than the depth of the second receiving cavity 1131, that is, the depth of the first receiving cavity 114 recessed in the direction of the stator assembly 12 is greater than the depth of the second receiving cavity 1131 recessed in the direction of the stator assembly 12. In this way, the overall width of the stator base 11 can be reduced, which is beneficial to the miniaturization of the stator module 10.

[0061] Please continue reading. Figure 3 Furthermore, the first receiving cavity 114 and the mounting groove 112A are at least partially offset in the width direction. It is understood that the projections of the first receiving cavity 114 and the mounting groove 112A in the width direction do not completely overlap. This serves two purposes: firstly, it fully utilizes the space of the stator base 11, making the structure of the stator module 10 more compact; secondly, it ensures the overall support of the stator base 11 for the mover module 20. That is, the at least partial offset of the first receiving cavity 114 and the mounting groove 112A in the width direction reduces the problem of local stress concentration in the stator base 11.

[0062] Please see Figure 4 In some embodiments, the cover plate 13 includes a cover body 131 and two snap-fit ​​portions 132. The cover body 131 is used to cover the opening 115 of the first receiving cavity 114, and is typically flat or thin-shell shaped. The two snap-fit ​​portions 132 are respectively connected to the upper and lower ends of the cover body 131. It can be understood that when the cover plate 13 is placed over the opening 115, the two snap-fit ​​portions 132 pass through the opening 115 and snap into the groove wall of the first receiving cavity 114. That is, when the cover plate 13 moves axially along the opening 115, the snap-fit ​​portions 132 undergo elastic deformation due to the pressure of the groove wall. After the snap-fit ​​portion 132 passes through the groove wall, the elastic restoring force causes it to expand outward, forming an interference fit or hook connection with the groove wall. In this way, after the cover body 131 completely covers the opening 115, the snap-fit ​​portions 132 bear the separation force perpendicular to the opening 115, preventing the cover plate 13 from falling off, thereby realizing the assembly of the cover plate 13 onto the second side wall 113. It should be noted that the cover body 131 and the two snap-fit ​​parts 132 are integral components to enhance the structural strength of the cover plate 13.

[0063] Please continue reading. Figure 4 Furthermore, in some embodiments, the second sidewall 113 also has two grooves 119, which are located on the upper and lower sides of the opening 115 and communicate with the opening 115; the cover plate 13 also includes two protrusions 133, which are located at the upper and lower ends of the cover body 131; that is, in the vertical direction, the two protrusions 133 protrude from the cover body 131. Thus, when the cover plate 13 is placed over the opening 115, the protrusions 133 extend into the grooves 119, so that the outer surface of the cover body 131 does not protrude from the second sidewall 113, that is, the outer surface of the cover body 131 is flush with the second sidewall 113, so as to avoid the stator module 10 occupying too much space. In addition, the shape of the grooves 119 and the protrusions 133 can restrict the installation direction of the cover plate 13 to avoid reverse installation or misalignment.

[0064] It should be noted that the protrusion 133, the cover body 131, and the snap-fit ​​part 132 in this embodiment of the application can be an integral component to reduce assembly steps and improve the structural strength of the cover plate 13.

[0065] Please see Figure 3In some embodiments, the stator base 11 also has a first ventilation opening 14, which is located on the second side wall 113 and is connected to the opening 115. That is, the first ventilation opening 14 is connected to the first receiving cavity 114, and a connector is provided in the first receiving cavity 114. When working, the connector will generate heat, and external air is introduced through the first ventilation opening 14 to form a heat dissipation path that guides the heat to the outside through the first receiving cavity 114 and the first ventilation opening 14, so as to reduce the temperature of the connector.

[0066] In some embodiments, a fan is provided in the accommodating cavity inside the stator base 11, and an air duct is formed between the fan and the first ventilation port 14 to accelerate the heat dissipation of the circuit integrated board 60 and the connector.

[0067] Please continue reading. Figure 3 In other embodiments, the cover plate 13 has a second vent 19 that penetrates the cover plate 13; that is, the second vent 19 communicates with the first receiving cavity 114. Thus, during operation, the connector generates heat, and external air is introduced through the first vent 14 to form a heat dissipation path that guides the heat to the outside through the first receiving cavity 114 and the first vent 14, thereby reducing the temperature of the connector. Multiple second vents 19 are used to improve heat dissipation efficiency. A heat dissipation airflow is formed between the fan and the second vents 19 to accelerate heat dissipation.

[0068] In some other embodiments, the stator base 11 also has a first vent 14 located on the second side wall 113 and connected to the opening 115. At the same time, the cover plate 13 has a second vent 19 penetrating the cover plate 13 so that the second vent 19 is connected to the first receiving cavity 114. That is, heat is dissipated through both the first vent 14 and the second vent 19 to accelerate the heat dissipation efficiency.

[0069] Of course, the stator module 10 also includes a circuit board, which is fixed in the internal cavity of the stator base 11. The circuit board is electrically connected to the circuit integration board 60 to supply power to the circuit integration board 60 and transmit signals. The circuit integration board 60 is electrically connected to the stator winding to realize the periodic excitation control of the stator winding. During the movement of the mover module 20, a large amount of heat will be generated. Therefore, the heat generated by the stator winding can also be dissipated through the first ventilation port 14 and the second ventilation port 19 mentioned above.
