[0047] The following describes the levitation motor 1000 according to an embodiment of the present application with reference to the accompanying drawings.

[0048] As shown in FIG1 , a suspension motor 1000 according to an embodiment of the present application includes a stator assembly 100 and a mover assembly 200 .

[0049] As shown in Figures 1 and 3, the mover assembly 200 and the stator assembly 100 are coupled to enable the mover assembly 200 to move back and forth. One of the mover assembly 200 and the stator assembly 100 is provided with a mounting cavity 210, and the other is provided with a guide member 110. The mounting cavity 210 has two side walls 212 arranged opposite to each other in the moving direction of the mover assembly 200. A mating member 220 is provided in the mounting cavity 210. The opposite ends of the mating member 220 extend at least to the two side walls 212 of the mounting cavity 210. The mating member 220 is connected to the two side walls 212 of the mounting cavity 210. The guide member 110 extends into the mounting cavity 210 and slides with the mating member 220. What this means is that when the mover assembly 200 is provided with an installation cavity 210, the stator assembly 100 is provided with a guide member 110; when the stator assembly 100 is provided with an installation cavity 210, the mover assembly 200 is provided with a guide member 110. In this way, when the guide member 110 extends into the installation cavity 210 and slides with the mating member 220, the sliding fit of the mover assembly 200 and the stator assembly 100 can be achieved, so that the mover assembly 200 and the stator assembly 100 can be reliably positioned, so as to guide the mover assembly 200 to move relative to the stator assembly 100, to avoid the displacement of the mover assembly 200 during the movement to a certain extent, and to ensure the accuracy of the movement of the mover assembly 200.

[0050] At the same time, by extending the opposite ends of the mating piece 220 at least to the two side walls 212 of the installation cavity 210 and setting the mating piece 220 to be connected to the two side walls 212 of the installation cavity 210, the opposite ends of the mating piece 220 can be fixed when the guide piece 110 and the mating piece 220 are slidingly engaged, thereby improving the position stability of the mating piece 220, so that the guide piece 110 and the mating piece 220 can form a stable sliding engagement, so that the stator assembly 100 and the mover assembly 200 can slide stably, further ensuring the accuracy of the movement of the mover assembly 200 and improving the working performance of the suspension motor 1000.

[0051] It should be noted that the moving direction of the movable sub-assembly 200 mentioned above can be understood as the up-down direction shown in FIG1 , that is, the movable sub-assembly 200 can move along the up-down direction of the suspension motor 1000, and the mounting cavity 210 has two side walls 212 arranged opposite to each other in the up-down direction, and the opposite ends of the mating piece 220 extend at least to the two side walls 212 of the mounting cavity 210, so as to facilitate the connection between the mating piece 220 and the two side walls 212 of the mounting cavity 210, and facilitate the use of the side walls 212 of the mounting cavity 210 to support the mating piece 220, thereby improving the positional stability of the mating piece 220.

[0052] As can be seen from the above structure, the levitation motor 1000 of the embodiment of the present application controls the relative displacement of the mover assembly 200 and the stator assembly 100 by providing the matching member 220 and the guide member 110, thereby ensuring the accuracy of the movement of the mover assembly 200 and improving the working performance of the levitation motor 1000.

[0053] At the same time, the opposite ends of the mating piece 220 are respectively connected to the two side walls 212 of the mounting cavity 210 to improve the position stability of the mating piece 220, thereby improving the stability of the sliding fit between the guide piece 110 and the mating piece 220, so that the stator assembly 100 and the mover assembly 200 can slide stably, further ensuring the accuracy of the movement of the mover assembly 200.

[0054] That is to say, the present application not only sets up the fitting part 220 and the guide part 110, but also connects the opposite ends of the fitting part 220 to the two side walls 212 of the installation cavity 210 respectively, so as to maximize the stable sliding fit between the guide part 110 and the fitting part 220.

[0055] It can be understood that compared with the related art, the present application sets a sliding fitting fitting 220 and a guide member 110 to limit the position of the mover assembly 200 and the stator assembly 100 during the relative movement process, and connects the opposite ends of the fitting 220 to the two side walls 212 of the installation cavity 210 respectively to maximize the stable sliding fit between the guide member 110 and the fitting 220, thereby ensuring the accuracy of the movement of the mover assembly 200 and improving the working performance of the suspension motor 1000.

[0056] It should be noted that, in the present application, the mover assembly 200 and the stator assembly 100 are arranged to be coupled so that the mover assembly 200 can move back and forth, thereby reducing the difficulty of controlling the movement of the mover assembly 200, thereby reducing the difficulty of controlling the suspension motor 1000, and ensuring the working performance of the suspension motor 1000.

[0057] The reciprocating movement of the movable subassembly 200 means that the movable subassembly 200 can reciprocate relative to the stator assembly 100 , that is, the movable subassembly 200 and the stator assembly 100 can move relative to each other.

[0058] In some embodiments, as shown in FIG1 , one of the mover assembly 200 and the stator assembly 100 is provided with a magnet 250 , and the other is provided with a coil winding 120 suitable for energizing. The magnet 250 and the coil winding 120 cooperate to achieve coupling of the stator assembly 100 and the mover assembly 200 , thereby enabling the mover assembly 200 to reciprocate relative to the stator assembly 100 to ensure the working performance of the levitation motor 1000 .

[0059] It can also be understood here that the suspension motor 1000 is used to drive the mover assembly 200 to move back and forth relative to the stator assembly 100, so that when the suspension motor 1000 is used in the suspension system, it can effectively buffer the impact transmitted by the road surface and improve the smoothness of the vehicle.

[0060] In a specific example, during the operation of the levitation motor 1000, the coil winding 120 is energized, and the energized coil winding 120 generates a magnetic field to cause the magnet 250 to produce linear motion. At this time, the magnet 250 and the coil winding 120 cooperate to achieve the coupling cooperation of the stator assembly 100 and the mover assembly 200 (the cooperation of the magnet 250 and the coil winding 120 to achieve the working principle of the levitation motor 1000 belongs to the existing technology and will not be repeated here), thereby enabling the mover assembly 200 to move back and forth relative to the stator assembly 100 to achieve the purpose of vibration reduction.

[0061] Optionally, the magnet 250 is a permanent magnet or an electropermanent magnet.

[0062] In a specific example, the suspension motor 1000 of the present application is a motor that generates different damping forces when the mover assembly 200 moves up and down by adjusting the cross-sections of the air flow channels in the upper and lower parts of the suspension motor 1000 .

[0063] In some embodiments, as shown in FIG1 , the mating piece 220 extends along the moving direction of the mover assembly 200. This ensures that the opposite ends of the mating piece 220 can extend at least to the two side walls 212 of the mounting cavity 210 to achieve connection between the mating piece 220 and the two side walls 212 of the mounting cavity 210. At the same time, it can also ensure that during the movement of the mover assembly 200, the guide piece 110 can slide with the mating piece 220, thereby achieving reliable positioning of the mover assembly 200 and the stator assembly 100, avoiding displacement of the mover assembly 200 during movement to a certain extent, ensuring the accuracy of the movement of the mover assembly 200, and thus ensuring the working performance of the suspension motor 1000.

[0064] In some embodiments, as shown in conjunction with Figures 1, 2, and 4, one of the mover assembly 200 and the stator assembly 100 includes a housing 230 and an end cap 240. The end cap 240 is disposed on the housing 230 and cooperates with the housing 230 to form a mounting cavity 210. One end of the mating member 220 is connected to the end cap 240, and the other end is connected to the housing 230. This achieves the purpose of connecting the opposing ends of the mating member 220 to the two side walls 212 of the mounting cavity 210, thereby securing the opposing ends of the mating member 220 and improving the positional stability of the mating member 220, thereby enabling the guide member 110 and the mating member 220 to form a stable sliding fit.

[0065] At the same time, by providing the end cover 240 to cooperate with the housing 230 to form the installation cavity 210, the difficulty of forming the installation cavity 210 can be reduced, thereby improving the production efficiency of the suspension motor 1000.

[0066] In some embodiments, a side wall of the housing 230 facing the end cover 240 forms one side wall 212 of the mounting cavity 210, and a side wall of the end cover 240 facing the housing 230 forms the other side wall 212 of the mounting cavity 210. In this way, when one end of the mating part 220 is connected to the end cover 240 and the other end is connected to the housing 230, the mating part 220 can be connected to the two side walls 212 of the mounting cavity 210, thereby improving the position stability of the mating part 220.

[0067] In a specific example, as shown in Figures 1, 2 and 4, a guide member 110 is provided on the stator assembly 100, and the mover assembly 200 includes a shell 230 and an end cover 240. The end cover 240 is provided on the shell 230, and the end cover 240 cooperates with the shell 230 to form an installation cavity 210. The guide member 110 extends into the installation cavity 210 and slides with the mating member 220, so that the guide member 110 and the mating member 220 can form a sliding fit and reduce the difficulty of forming the installation cavity 210.

[0068] In some embodiments, as shown in Figure 1, the mover assembly 200 includes a magnet 250, which is arranged in the installation cavity 210 and located on the inner wall of the installation cavity 210. The stator assembly 100 includes a coil winding 120, which is arranged on the guide member 110. The coil winding 120 and the magnet 250 cooperate to enable the mover assembly 200 to move reciprocatingly.

[0069] Among them, by arranging the coil winding 120 on the guide member 110, the guide member 110 can also be constructed as a fixing member of the coil winding 120 to support the coil winding 120 and improve the position stability of the coil winding 120, thereby facilitating the use of the coil winding 120 and the magnet 250 to cooperate in controlling the reciprocating movement of the mover assembly 200 relative to the stator assembly 100.

[0070] In some embodiments, the end cap 240 is detachably connected to the housing 230 , so that the end cap 240 is fixedly connected to the housing 230 while reducing the difficulty of installing the structural components in the installation cavity 210 .

[0071] In some embodiments, as shown in Figures 1, 2, and 3, an opening 211 is formed on the end cap 240, communicating with the mounting cavity 210. The guide member 110 slides with the mating member 220 through the opening 211. This reduces the difficulty of sliding the guide member 110 and the mating member 220, thereby reducing the difficulty of assembling the levitation motor 1000.

[0072] In a specific example, one end of the guide member 110 extends into the installation cavity 210 through the opening 211 , so as to achieve sliding fit between the guide member 110 and the fitting member 220 .

[0073] In some embodiments, as shown in FIG1 , the guide member 110 is externally mounted on the mating member 220. This facilitates the sliding fit between the guide member 110 and the mating member 220, while also reducing the difficulty of assembling the guide member 110 and the mating member 220. This facilitates the sliding fit between the mover assembly 200 and the stator assembly 100, allowing the mover assembly 200 and the stator assembly 100 to be reliably positioned, thereby guiding the movement of the mover assembly 200 and, to a certain extent, preventing the mover assembly 200 from deflecting during movement, thereby ensuring the accuracy of the movement of the mover assembly 200.

[0074] In some embodiments, as shown in Figures 1 and 5, a guide channel 114 is provided at one end of the guide member 110 facing the mating member 220, and the mating member 220 can be slidably fitted in the guide channel 114 to achieve sliding fit between the guide member 110 and the mating member 220, thereby reducing the difficulty of fit between the guide member 110 and the mating member 220, thereby facilitating guiding the mover assembly 200 to move in a predetermined direction, and to a certain extent avoiding the displacement of the mover assembly 200 during the movement process, thereby ensuring the accuracy of the movement of the mover assembly 200 and thus ensuring the working performance of the suspension motor 1000.

[0075] In some embodiments, the inner wall surface of the guide member 110 and the outer surface of the fitting member 220 are both formed into high-precision smooth surfaces, which is beneficial to reducing the friction resistance between the fitting member 220 and the guide member 110, so that the fitting member 220 and the guide member 110 form a sliding fit.

[0076] In some embodiments, as shown in conjunction with Figures 1, 2, and 3, a connecting rib 241 is provided at the opening 211 to form a plurality of sub-openings 2111 in the opening 211. One end of the mating piece 220 is connected to the end cap 240 via the connecting rib 241, and a portion of the guide piece 110 is passed through the sub-opening 2111. By forming the opening 211 on the end cap 240 and arranging a portion of the guide piece 110 to be passed through the sub-opening 2111, the installation cavity 210 is formed with the opening 211, and the guide piece 110 can extend into the installation cavity 210 through the opening 211, thereby achieving sliding fit between the guide piece 110 and the mating piece 220 and reducing the difficulty of fit between the guide piece 110 and the mating piece 220.

[0077] At the same time, by setting a connecting rib 241 at the opening 211 and connecting one end of the fitting 220 to the end cover 240 through the connecting rib 241, the fitting 220 and the end cover 240 are connected and matched, thereby fixing one end of the fitting 220, reducing the difficulty of fixing one end of the fitting 220, and improving the position stability of the fitting 220.

[0078] In some embodiments, as shown in Figures 2 and 3 , a plurality of connecting ribs 241 are provided at the opening 211, and the plurality of connecting ribs 241 are spaced apart along the circumference of the opening 211. The plurality of connecting ribs 241 can enhance the connection strength between the mating member 220 and the end cap 240, further improving the positional stability of the mating member 220, enabling the guide member 110 and the mating member 220 to form a stable sliding fit, thereby ensuring the accuracy of the movement of the movable subassembly 200.

[0079] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0080] In some embodiments, as shown in Figures 2 and 3, two connecting ribs 241 are provided at the opening 211. The two connecting ribs 241 cooperate to increase the connection strength between the mating piece 220 and the end cover 240, while also preventing the connecting ribs 241 from occupying too much space at the opening 211, thereby ensuring that the guide piece 110 can extend into the installation cavity 210 through the opening 211 and slide with the mating piece 220, thereby reducing the difficulty of cooperation between the guide piece 110 and the mating piece 220.

[0081] In some embodiments, as shown in FIG3 , a reinforcing rib 242 is further connected between the end cap 240 and the mating piece 220. In the moving direction of the movable subassembly 200, the reinforcing rib 242 is connected to the connecting rib 241 and is located on one side of the connecting rib 241. This means that the reinforcing rib 242 is connected to the connecting rib 241 and is located on one side of the connecting rib 241 in the moving direction of the movable subassembly 200. Connecting the reinforcing rib 242 between the end cap 240 and the mating piece 220 improves the connection strength between the end cap 240 and the mating piece 220, ensures the stability of the connection between the end cap 240 and the mating piece 220, and thereby improves the positional stability of the mating piece 220. By arranging the reinforcing rib 242 on one side of the connecting rib 241, the reinforcing rib 242 is prevented from occupying the space at the opening 211, thereby further ensuring that the guide member 110 can extend through the opening 211 into the mounting cavity 210 and slideably engage with the mating piece 220.

[0082] That is to say, the reinforcing rib 242 of the present application can improve the connection strength between the end cover 240 and the fitting 220 while preventing the reinforcing rib 242 from occupying the space at the opening 211 .

[0083] In some embodiments, the end cap 240, the connecting rib 241, and the mating piece 220 are integrally formed. Alternatively, the connecting rib 241 and the mating piece 220 may be integrally formed on the end cap 240. This eliminates the need for connections between the end cap 240, the connecting rib 241, and the mating piece 220, improving molding efficiency. Furthermore, the molding difficulty of the connecting rib 241, the mating piece 220, and the end cap 240 is reduced, while ensuring the quality of the connection between the connecting rib 241, the mating piece 220, and the end cap 240. This allows the end cap 240 to support the mating piece 220, improving the positional stability of the mating piece 220 and thereby ensuring the performance of the mating piece 220.

[0084] In some embodiments, the connecting rib 241 and the reinforcing rib 242 are an integral part, so that the end cover 240, the connecting rib 241, the fitting 220 and the reinforcing rib 242 are all formed as an integral part, ensuring the connection strength between the end cover 240, the connecting rib 241, the fitting 220 and the reinforcing rib 242, making the relative positions of the end cover 240, the connecting rib 241, the fitting 220 and the reinforcing rib 242 stable and reducing the difficulty of connection.

[0085] In some embodiments, as shown in conjunction with FIG1 and FIG4 , a connection hole 231 is provided on a side wall of the housing 230 facing the end cap 240. The other end of the mating piece 220 is engaged and connected in the connection hole 231. This ensures a fixed connection between the other end of the mating piece 220 and the housing 230, thereby facilitating support of the mating piece 220 by the housing 230, improving the positional stability of the mating piece 220, and ensuring the working performance of the mating piece 220.

[0086] In summary, one end of the mating piece 220 of the present application is connected to the end cover 240 through a connecting rib 241, and the other end is connected to a side wall of the shell 230 facing the end cover 240 through a connecting hole 231, so that the opposite ends of the mating piece 220 can be respectively connected to the two side walls 212 of the mounting cavity 210, thereby fixing the opposite ends of the mating piece 220, improving the position stability of the mating piece 220, and enabling the guide piece 110 and the mating piece 220 to form a stable sliding fit.

[0087] At the same time, by setting the connecting hole 231 to achieve a fixed connection between the other end of the fitting 220 and the shell 230, the connection difficulty of the fitting 220 and the shell 230 can be reduced, the connection efficiency can be improved, and the fitting 220 and the shell 230 can form a detachable connection, which can facilitate the separate processing of the fitting 220 and reduce the molding difficulty of the fitting 220.

[0088] In some embodiments, the fitting 220 is interference-fitted with the connection hole 231. This increases the connection strength between the fitting 220 and the housing 230, effectively supports the fitting 220 with the housing 230, and improves the positional stability of the fitting 220. Furthermore, the fitting 220 and the housing 230 are detachably connected, reducing the difficulty of connecting the fitting 220 and the housing 230.

[0089] It should be noted that since the mating part 220 forms a detachable connection with the housing 230, after the surface of the mating part 220 is processed with high precision, the surface of the mating part 220 can also be plated to improve the surface smoothness and wear resistance of the mating part 220 and reduce the friction resistance between the mating part 220 and the guide part 110. In this way, while allowing the mating part 220 and the guide part 110 to form a sliding fit, the service life of the mating part 220 and the guide part 110 can also be extended, thereby reducing the cost of use.

[0090] In some embodiments, as shown in Figures 1 and 5 , the guide member 110 is disposed outside the mating member 220 and has an escape channel 111 for circumventing the connecting rib 241. The escape channel 111 ensures that a portion of the guide member 110 can be effectively assembled into the mounting cavity 210 and slidably engage with the mating member 220.

[0091] In some embodiments, in combination with Figures 7 and 8, during the assembly process of the guide member 110, the guide member 110 can be fixed first, and then the end cover 240 connected to the mating member 220 can be controlled to pass through the guide member 110 from top to bottom. In this way, after the assembly is completed, when the shell 230 is mated with the end cover 240 from bottom to top, at least part of the structure of the guide member 110 can be located in the installation cavity 210 and slidably matched with the mating member 220 (as shown in Figure 9).

[0092] It should be noted that when the end cover 240 of the control connection fitting 220 passes through the guide member 110 from top to bottom, the connecting rib 241 on the end cover 240 faces the avoidance channel 111 of the guide member 110, so that other structures of the guide member 110 (such as the second part 113 below) can face the opening 211 on the end cover 240, so that the end cover 240 can pass through the guide member 110.

[0093] In some embodiments, as shown in FIG5 , the guide member 110 includes a first portion 112 and a second portion 113. The first portion 112 is slidably engaged with the mating member 220. A plurality of second portions 113 are spaced apart and connected to the first portion 112. Adjacent second portions 113 define an escape channel 111 for escaping the connecting rib 241. The plurality of second portions 113 are disposed through the opening 211. This reduces the difficulty of forming the escape channel 111. While ensuring that the guide member 110 can be effectively assembled and inserted into the installation cavity 210, the first portion 112 can also be utilized to achieve a slidable engagement between the guide member 110 and the mating member 220, thereby ensuring the operating performance of the guide member 110.

[0094] In the description of this application, features defined as "first" or "second" may explicitly or implicitly include one or more such features, and are used to distinguish and describe features, without any distinction in order or importance.

[0095] In some embodiments, as shown in Figures 2 and 3, two connecting ribs 241 are provided at the opening 211. The two connecting ribs 241 are arranged at intervals along the circumference of the opening 211, and a sub-opening 2111 is formed between two adjacent connecting ribs 241. The sub-opening 2111 corresponds one-to-one to the second part 113, so that the end cover 240 can pass through the second part 113 from the sub-opening 2111, thereby facilitating the assembly of the guide member 110 into the installation cavity 210 through the opening 211.

[0096] In some embodiments, as shown in Figure 5, the guide channel 114 is formed on the first part 112. During the assembly of the guide member 110, the first part 112 is used to be arranged in the installation cavity 210 and close to the mating member 220. By forming the guide channel 114 on the first part 112, it is easy to achieve the sliding fit between the mating member 220 and the guide member 110. At the same time, the guide channel 114 can be set away from the avoidance channel 111 to avoid interference between the guide channel 114 and the avoidance channel 111.

[0097] In some embodiments, as shown in FIG1 , the end of each second portion 113 away from the first portion 112 is fixedly mated with a tower top 300. The tower top 300 is adapted to be fixed to a vehicle body, and at least a portion of the first portion 112 is used to mount a magnetic member. By fixing the end of each second portion 113 away from the first portion 112 with the tower top 300, the levitation motor 1000 can be connected to the vehicle body, thereby achieving a mating connection between the levitation motor 1000 and the vehicle. This facilitates utilizing the levitation motor 1000 to cushion impacts from the road during vehicle travel, improving vehicle ride comfort, and reducing the difficulty of connecting the levitation motor 1000 to the vehicle.

[0098] At the same time, by fixing the end of each second part 113 away from the first part 112 to the tower top 300, the tower top 300 can also be used to fix the second part 113, thereby improving the position stability of the second part 113, thereby improving the position stability of the guide member 110, so that the guide member 110 and the mating member 220 can form a sliding fit.

[0099] In addition, by configuring at least a portion of the first part 112 to be used for setting up a magnetic component, the magnetic component can be assembled on the first part 112. While using the first part 112 to support the magnetic component, it is also convenient to achieve the coupling and cooperation between the stator assembly 100 and the mover assembly 200, so that the mover assembly 200 can move back and forth relative to the stator assembly 100 to ensure the working performance of the suspension motor 1000.

[0100] It should be noted that the magnetic component mentioned here can be understood as the coil winding 120 mentioned above.

[0101] In some embodiments, the end of the second part 113 away from the first part 112 is provided with a protrusion and an external thread, the tower top 300 passes through the end of the second part 113 and stops on the protrusion, and then the connecting nut 600 is used to cooperate with the external thread on the second part 113, and the connecting nut 600 and the protrusion respectively stop on opposite sides of the partial structure of the tower top 300 to achieve a fixed connection between the second part 113 and the tower top 300.

[0102] In summary, the guide member 110 of the present application not only has a guiding function, but also has a connecting function for the tower top 300 .

[0103] In some embodiments, as shown in FIG1 , a lower fork arm 260 is provided at the end of the housing 230 away from the guide member 110. The housing 230 is connected to the wheel end of the vehicle via the lower fork arm 260. This allows the suspension motor 1000 to be installed on the vehicle, thereby achieving a coordinated connection between the suspension motor 1000 and the vehicle. This facilitates the use of the suspension motor 1000 to cushion the impact of the road during driving, improve the vehicle's ride comfort, and enhance the user experience.

[0104] That is to say, one end of the suspension motor 1000 of the present application is connected to the body end of the vehicle through the tower top 300, and the other end is connected to the wheel end of the vehicle through the lower fork arm 260, thereby realizing the assembly of the suspension motor 1000 to the vehicle and reducing the difficulty of connecting the suspension motor 1000 to the vehicle.

[0105] In a specific example, the suspension motor 1000 is installed between the wheel end and the body end of the vehicle. When the wheel moves up and down relative to the body, the mover assembly 200 moves relative to the stator assembly 100. At this time, the stator assembly 100 and the mover assembly 200 can be used to cooperate to transmit the force and torque acting between the wheel and the body, reducing the impact load transmitted to the body by the road surface. At the same time, the noise input by the road surface and tires can be isolated to ensure the comfort of the vehicle and enhance the driving experience.

[0106] Of course, in some other embodiments, the tower top 300 may also be connected to the wheel end of the vehicle, and the lower wishbone 260 may be connected to the body end of the vehicle, which is not specifically limited here.

[0107] In some embodiments, as shown in Figure 5, a first heat dissipation channel 1151 is provided on the first part 112, and a second heat dissipation channel 1152 is provided on the second part 113. The first heat dissipation channel 1151 is connected to the second heat dissipation channel 1152. A water inlet 1153 and a water outlet 1154 connected to the second heat dissipation channel 1152 are provided on the side of the second heat dissipation channel 1152 away from the first part 112. By setting up, external cooling water can enter the second heat dissipation channel 1152 through the water inlet 1153. Since the second heat dissipation channel 1152 is connected to the first heat dissipation channel 1151, the water entering the second heat dissipation channel 1152 can flow to the first heat dissipation channel 1151. Since the first heat dissipation channel 1151 is formed on the first part 112 and the first part 112 is located in the installation cavity 210, the cooling water in the first part 112 can be used to cool and dissipate heat of the coil winding 120, thereby ensuring the heat dissipation effect, so that the temperature of the coil winding 120 can be maintained within a suitable temperature range, which is beneficial to extending the service life of the suspension motor 1000 and improving the working stability of the suspension motor 1000.

[0108] In addition, the cooling water after cooling and dissipating the heat of the coil winding 120 can also be discharged in sequence through the second heat dissipation channel 1152 and the water outlet 1154 to facilitate the circulation of the cooling water, so that the temperature of the cooling water in the first heat dissipation channel 1151 can always be maintained within an appropriate range, ensuring the heat dissipation effect and improving the heat dissipation capacity of the suspension motor 1000.

[0109] That is to say, the present application dissipates heat from the suspension motor 1000 by setting the first heat dissipation channel 1151 and the second heat dissipation channel 1152 , thereby improving the heat dissipation capacity of the suspension motor 1000 , which is beneficial to extending the service life of the suspension motor 1000 and improving the working stability of the suspension motor 1000 .

[0110] It should be noted that the coil winding 120 generates heat when it is energized. If the heat dissipation is poor, the internal temperature of the suspension motor 1000 will rise, and there is a risk of burning the suspension motor 1000. Therefore, the present application sets a first heat dissipation channel 1151 and a second heat dissipation channel 1152 in the guide member 110 to prevent the suspension motor 1000 from burning and extend the service life of the suspension motor 1000.

[0111] At the same time, since the coil winding 120 is cooled, the temperature of the stator assembly 100 can be prevented from exceeding the upper limit value, so that the suspension motor 1000 of the present application can operate under high current conditions, thereby improving the peak thrust and rated thrust output by the suspension motor 1000, thereby ensuring the working performance of the suspension motor 1000.

[0112] In summary, the guide member 110 of the present application not only has a guiding function, but also has a connection function of the tower top 300 and a heat dissipation function.

[0113] In some embodiments, as shown in conjunction with FIG1 and FIG5 , the levitation motor 1000 further includes a sensor assembly 400. At least a portion of the mating member 220 is slidably engaged within the avoidance channel 111. The sensor assembly 400 is disposed within the avoidance channel 111 to detect the movement position of the mover assembly 200. This allows accurate determination of the position of the mover assembly 200, facilitates control of the movement of the mover assembly 200, ensures the position accuracy of the mover assembly 200 after movement, improves the operating performance of the levitation motor 1000, and, to a certain extent, avoids the technical problem of control precision defects.

[0114] In some embodiments, as shown in conjunction with FIG1 and FIG5 , the sensor assembly 400 includes a reading head 410 and a reference member 420. One of the reading head 410 and the reference member 420 is disposed on the inner wall of the avoidance channel 111, and the other is disposed on the mating member 220. The reading head 410 and the reference member 420 cooperate to detect the movement position of the movable subassembly 200. This facilitates accurate determination of the position of the movable subassembly 200 while reducing the detection difficulty of the sensor assembly 400 and ensuring detection accuracy.

[0115] In some embodiments, as shown in Figures 1 and 5, the reference member 420 is arranged on the inner wall of the avoidance channel 111, and the reading head 410 is arranged on the matching member 220. In this way, when the guide member 110 and the matching member 220 move relative to each other, the reference member 420 and the reading head 410 can be used to cooperate to detect the moving position of the movable assembly 200 to ensure the accuracy of the detection.

[0116] In some embodiments, as shown in FIG2 , the reading head 410 is disposed on the connecting rib 241, and the reading head 410 and the mating component 220 are respectively located on either side of the end cap 240. This allows for the rational use of the space on the end cap 240, so that both the reading head 410 and the mating component 220 can be disposed on the end cap 240. This facilitates the use of the end cap 240 to support the reading head 410 and the mating component 220, improves the positional stability of the reading head 410 and the mating component 220, and thereby ensures the working performance of the reading head 410 and the mating component 220.

[0117] Optionally, the reading head 410 is connected to the end of the end cover 240 connected to the mating part 220 by bolts to achieve the setting of the reading head 410 on the mating part 220, ensure the connection strength between the reading head 410 and the mating part 220, and improve the position stability of the reading head 410.

[0118] Of course, in other embodiments, the reference member 420 may be disposed on the matching member 220 , and the reading head 410 may be disposed on the inner wall of the avoidance channel 111 .

[0119] In some embodiments, the reference part 420 is a magnetic grating, which is embedded in the inner wall of the avoidance channel 111 and the reading head 410 fixed on the mating part 220 senses the changes in the magnetic field of the magnetic grating to obtain accurate position information, thereby detecting the position of the mover assembly 200 relative to the stator assembly 100.

[0120] Among them, by arranging the reference member 420 on the inner wall of the avoidance channel 111, the space is cleverly utilized, thereby preventing the reference member 420 from occupying other space of the suspension motor 1000, thereby improving space utilization.

[0121] In addition, when the sensor assembly 400 of the present application is a Hall sensor or other sensor that generates a magnetic field, arranging the reference part 420 on the inner wall of the avoidance channel 111 can also avoid the influence of the coil winding 120 or the magnet 250 in the installation cavity 210 on the sensor assembly 400, thereby avoiding electromagnetic interference, which is more conducive to the operation of the sensor assembly 400.

[0122] In some embodiments, a wiring groove is provided on the outer side of the peripheral wall of the guide member 110 for guiding the routing of the wire 500. The wire 500 is a lead wire of the coil winding 120 of the levitation motor 1000 (the specific structure of the wire 500 can be seen in FIG6 ). The provision of the wire 500 facilitates the electrical connection of the coil winding 120, thereby ensuring the working performance of the coil winding 120. Furthermore, the provision of the wiring groove on the outer side of the peripheral wall of the guide member 110 for guiding the routing of the wire 500 reduces the difficulty of routing the wire 500. The wiring groove can also be used to secure the wire 500, ensuring the positional stability of the wire 500 and preventing the wire 500 from bending as the levitation motor 1000 moves, thereby affecting signal transmission. This improves the reliability of the levitation motor 1000, and can also protect the wire 500 using the wiring groove, extending the service life of the wire 500, improving the safety of the wire 500, and improving the reliability of the wire 500.

[0123] Optionally, the wiring trough is integrally formed with the guide member 110. That is, the wiring trough is integrally formed on the guide member 110 to reduce the difficulty of forming the wiring trough.

[0124] In some embodiments, as shown in FIG6 , the end of the guide member 110 away from the installation cavity 210 is fixedly engaged with the tower top 300 , and a wire outlet hole 310 connected to the wiring groove is provided on the tower top 300 to facilitate leading out the wire 500 through the wire outlet hole 310 , thereby reducing the difficulty of leading out the wire 500 and further reducing the difficulty of electrical connection of the coil winding 120 .

[0125] In summary, the levitation motor 1000 of the present application enables the mover assembly 200 and the stator assembly 100 to slide relative to each other under the cooperation of the fitting member 220 and the guide member 110 , thereby achieving the requirement of stable operation of the levitation motor 1000 .

[0126] In a specific example, during the assembly process of the levitation motor 1000, the first step is to first use the guide member 110 as the main body, attach the reference member 420 to the inner wall of the avoidance channel 111 of the guide member 110, and assemble the coil winding 120 on the outer periphery of the first part 112 of the guide member 110 (as shown in FIG7 ); the second step is to assemble the reading head 410 at the end of the connecting end cover 240 of the fitting member 220, and insert the guide member 110 into the structure completed in the first step (as shown in FIG8 ); the third step is mainly to assemble the structure completed in the second step with the outer shell 230, and to connect the other end of the fitting member 220 in the connecting hole 231 to fix the opposite ends of the fitting member 220 (as shown in FIG9 ); the fourth step is mainly to fix the end of each second part 113 away from the first part 112 with the tower top 300 (as shown in FIG1 ), thereby realizing the assembly connection of the levitation motor 1000.
