[0035] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 The motor 10 includes a front cover 101 , a rear cover 102 , a motor housing 103 , a first circuit board 104 , a second circuit board 105 , and a slip ring 106 .

[0036] Among them, the front end cover 101 and the rear end cover 102 are respectively covered with the two end openings of the motor housing 103; the first circuit board 104 is arranged outside the motor housing 103; the second circuit board 105 is arranged inside the motor housing 103 and abuts against the rear end cover 102; the slip ring 106 is arranged on the side of the front end cover 101 away from the motor housing 103, and the slip ring 106 includes a rotor 201 and a stator 202, the rotor 201 is connected to the first circuit board 104 through the first connecting component 301, and the stator 202 is connected to the second circuit board 105 through the second connecting component 302, and the slip ring 106 is configured to drive the rotor 201 to drive the first connecting component 301 to rotate in the same direction as the rotation direction of the first circuit board 104 when the first circuit board 104 rotates. The first circuit board 104 is electrically connected to the second circuit board 105 through the first connecting component 301 and the second connecting component 302 for transmitting USB (Universal Serial Bus) data.

[0037] In some embodiments, the first circuit board 104 is also used to transmit power supply signals, CAN (Controller Area Network) signals, CANFD (Controller Area Network Flexible Data-rate) signals, pulse signals, analog signals and digital signals with the second circuit board 105 through the first connecting component 301 and the second connecting component 302.

[0038] In some embodiments, the rear end cover 102 is integrally formed with the motor housing 103 or is detachably connected thereto, and the front end cover 101 is integrally formed with the motor housing 103 or is detachably connected thereto.

[0039] In some embodiments, the first connecting component 301 and the second connecting component 302 respectively include at least one wire, which is used to connect the first circuit board 104 and the rotor 201 in the slip ring 106, and to connect the second circuit board 105 and the stator 202 in the slip ring 106, so as to connect the first circuit board 104 and the second circuit board 105 through the slip ring 106.

[0040] It is understood that when the first connection component 301 and the second connection component 302 include multiple wires, the multiple wires can be used to transmit different signals. For example, two wires are included, one of which is used to transmit a USB signal and the other is used to transmit a power supply signal.

[0041] In some embodiments, both the first circuit board 104 and the second circuit board 105 are printed circuit boards (PCBs). The first circuit board 104 can be a circuit board of a driven device, which can be a car, a fan, an air conditioner, etc., without limitation. The second circuit board 105 can be a main control circuit board, configured to transmit signal data to the first circuit board 104 to control the first circuit board 104 and thereby control the driven device. The second circuit board 105 can also be configured to receive and respond to the signal data transmitted by the first circuit board 104.

[0042] It can be understood that since the rotor 201 in the slip ring 106 is electrically connected to the first circuit board 104 via the first connecting assembly 301, and the stator 202 in the slip ring 106 is electrically connected to the second circuit board 105 via the second connecting assembly 302, during actual operation, the first circuit board 104 rotates under the drive of an external force, and the rotor 201 and the first connecting assembly 301 rotate in the same direction as the first circuit board 104, while the stator 202, the second connecting assembly 302, and the second circuit board 105 remain stationary. This prevents the first connecting assembly 301 from becoming entangled or folded due to the first circuit board 104 rotating while the rotor 201 remains stationary. Furthermore, it prevents the first connecting assembly 301 from becoming entangled or folded due to the misalignment of the rotational directions of the first circuit board 104 and the rotor 201, thereby ensuring the stability and continuity of signal transmission between the first circuit board 104 and the second circuit board 105.

[0043] In some embodiments, a hub is provided on the first circuit board 104 and / or the second circuit board 105. The hub is connected to the first connection assembly 301 and / or the second connection assembly 302, and the slip ring 106 is connected to an external device through the hub. It is understood that the external device is a device coupled to the first circuit board 104 and / or the second circuit board 105. The external device can be a computer, a car, or other device.

[0044] In some embodiments, the slip ring 106 is fixed to the front end cover 101 by welding.

[0045] In some embodiments, a through hole is provided on the front end cover 101 , and at least a portion of the slip ring 106 passes through the through hole and abuts against the front end cover 101 .

[0046] In some embodiments, the slip ring 106 is detachably connected to the front end cover 101 and is secured to the front end cover 101 via fasteners. Specifically, the slip ring 106 and the front end cover 101 are each provided with a plurality of first and second connection holes spaced apart from each other, and fasteners can be inserted into the first and second connection holes to secure the slip ring 106 to the front end cover 101. The first connection hole is provided on the stator 202; the fastener is provided with an external thread, and the second connection hole is provided with an internal thread. The external thread of the fastener cooperates with the internal thread of the second connection hole to secure the slip ring 106 to the front end cover 101; the fastener may include a stud, a bolt, a screw, and / or a nut.

[0047] It is understandable that when the slip ring 106 is detachably connected to the front cover 101 , when the slip ring 106 is worn or damaged, the damaged or worn slip ring 106 can be replaced in a targeted manner to improve the utilization of other components of the motor 10 and save costs.

[0048] In some embodiments, the first circuit board 104 is disposed outside the motor housing 103. The actual location of the first circuit board 104 can be on the outer wall of the motor housing 103, or it can be in contact with other components of the motor 10, or other locations, which are not limited here.

[0049] In some embodiments, the second circuit board 105 and the rear end cover 102 are integrally formed or detachably connected.

[0050] In some embodiments, the second circuit board 105 is disposed in the motor housing 103, and the actual setting position of the second circuit board 105 may not be in contact with the rear end cover 102. For example, the second circuit board 105 is arranged parallel to the rear end cover 102 and there is a preset distance. The preset distance can be determined according to actual conditions. For example, the second circuit board 105 is disposed on the inner wall of the motor housing 103, or the second circuit board 105 is in contact with other components in the motor 10, or others, which are not limited here.

[0051] In the motor 10 provided in some embodiments of the present application, the slip ring 106 is disposed outside the motor housing 103. When the first circuit board 104 rotates, the rotor 201 and the first connecting component 301 in the slip ring 106 rotate together, while the stator 202, the second connecting component 302, and the second circuit board 105 in the slip ring 106 remain stationary. This can prevent the first connecting component 301 and / or the second connecting component 302 from being entangled or folded, thereby ensuring the continuity and stability of signal transmission.

[0052] See also Figure 3 and Figure 4 , Figure 3 is a schematic diagram of the structure of the motor in some embodiments of the present application, Figure 4 yes Figure 3The motor 10 is shown as a schematic cross-sectional view. The motor 10 comprises a front cover 101, a rear cover 102, a motor housing 103, a first circuit board 104, a second circuit board 105, a slip ring 106, and a sleeve 107. The slip ring 106 comprises a rotor 201 and a stator 202. The sleeve 107 is sleeved with the slip ring 106 on one side and abuts the front cover 101. The sleeve 107 is provided with the first circuit board 104 on the other side, which is in sliding connection with the sleeve 107. A first connecting assembly 301 is disposed within the sleeve 107 to connect the first circuit board 104 to the rotor 201.

[0053] It can be understood that the sleeve 107 is sleeved with the slip ring 106, and the first connecting component 301 used to electrically connect the rotor 201 and the first circuit board 104 in the slip ring 106 is also sleeved with the sleeve 107. At this time, the first connecting component 301 can pass through the internal space of the sleeve 107 to connect the first circuit board 104 and the rotor 201.

[0054] In some embodiments, the shape of the sleeve 107 can be cylindrical, cube, cuboid or other shapes, which are not limited here.

[0055] In some embodiments, the material of the sleeve 107 can be metal, plastic or other materials, which is not limited here.

[0056] In some embodiments, the size of the sleeve 107 can be set according to actual conditions without limitation. For example, the size of the sleeve 107 can be set according to the size of the slip ring 106 so that the slip ring 106 can be covered by the sleeve 107 .

[0057] In some embodiments, the sleeve 107 is fixed to the front end cover 101 by welding.

[0058] In some embodiments, the shaft sleeve 107 is detachably connected to the front end cover 101, and the shaft sleeve 107 is fixed to the front end cover 101 via fasteners. Specifically, the shaft sleeve 107 and the front end cover 101 are respectively provided with a plurality of third and fourth connection holes spaced apart from each other, and fasteners can be inserted into the third and fourth connection holes to secure the shaft sleeve 107 to the front end cover 101. The fasteners are provided with external threads, and the fourth connection holes are provided with internal threads. The external threads of the fasteners cooperate with the internal threads of the fourth connection holes to connect the shaft sleeve 107 to the front end cover 101. The fasteners can include studs, bolts, screws, and / or nuts.

[0059] It is understandable that when the shaft sleeve 107 is detachably connected to the front end cover 101, when the shaft sleeve 107 is worn or damaged, the damaged or worn shaft sleeve 107 can be replaced in a targeted manner to improve the utilization rate of other components of the motor 10 and save costs.

[0060] See also Figure 5 , Figure 5 1 is a schematic cross-sectional view of a motor in some embodiments of the present application. The motor 10 includes a front cover 101, a rear cover 102, a motor housing 103, a first circuit board 104, a second circuit board 105, a slip ring 106, a sleeve 107, and a motor shaft 108. The slip ring 106 includes a rotor 201 and a stator 202. The motor shaft 108 abuts the rear cover 102 and passes through the motor housing 103, the front cover 101, and the slip ring 106 in sequence. At least a portion of the motor shaft 108 is disposed within the sleeve 107. The motor housing 103 includes a wire groove 109, which is disposed around the motor shaft 108 and extends in the direction in which the motor shaft 108 is extended. The second connecting assembly 302 is disposed within the wire groove 109 to connect the second circuit board 105 and the stator 202.

[0061] In some embodiments, a preset distance is provided between the first circuit board 104 disposed on the sleeve 107 and the motor shaft 108 to prevent the motor shaft 108 from affecting the sleeve 107 and the first circuit board 104 disposed on the sleeve 107. The preset distance can be determined based on actual conditions and is not limited here.

[0062] In some embodiments, the motor shaft 108 is fixed to the rear end cover 102 by welding.

[0063] In some embodiments, the motor shaft 108 is detachably connected to the rear end cover 102 and is secured to the rear end cover 102 via fasteners. For example, the motor shaft 108 is threadedly connected to the rear end cover 102. In another example, the motor shaft 108 and the rear end cover 102 are each provided with a plurality of spaced-apart fifth and sixth connection holes, through which fasteners can be inserted to secure the motor shaft 108 to the rear end cover 102. The fasteners are provided with external threads, and the sixth connection holes are provided with internal threads. The external threads of the fasteners cooperate with the internal threads of the sixth connection holes to secure the motor shaft 108 to the rear end cover 102. The fasteners may include studs, bolts, screws, and / or nuts.

[0064] It is understandable that when the motor shaft 108 is detachably connected to the rear end cover 102 , the damaged or worn motor shaft 108 can be replaced in a targeted manner when the motor shaft 108 is worn or damaged, so as to improve the utilization rate of other components of the motor 10 and save costs.

[0065] In some embodiments, at least one wire groove 109 is provided on the inner wall of the motor housing 103 , and the wire groove 109 is provided around the motor shaft 108 in the motor housing 103 .

[0066] Specifically, the wire groove 109 is provided between the motor shaft 108 and the motor housing 103 , and the wire groove 109 is of a regular shape or an irregular shape.

[0067] In some embodiments, a cylindrical placement groove 110 is further provided on the inner wall of the motor housing 103. In this case, the space of the wire groove 109 is formed by the motor housing 103, the placement groove 110 and the motor shaft 108. The placement groove 110 is used to place the magnet.

[0068] In some embodiments, the placement slot 110 and the motor housing 103 are detachably connected or integrally formed.

[0069] In some embodiments, a first opening and a second opening are provided on the front end cover 101, and the opening of the wire groove 109 is provided corresponding to the first opening on the front end cover 101. The second connecting component 302 connected to the stator 202 in the slip ring 106 can pass through the second opening to be led out from the inside of the motor housing 103, and then pass through the wire groove 109 from the first opening to be electrically connected to the second circuit board 105.

[0070] It can be understood that when the first connection component 301 and the second connection component 302 include multiple wires, the multiple wires in the second connection component 302 can pass through the same wire trough 109 or different wire troughs 109 .

[0071] See also Figure 6 and Figure 7 , Figure 6 and Figure 7 These are schematic diagrams of the slip ring structure in some embodiments of the present application. The slip ring 106 includes a rotor 201 and a stator 202. The rotor 201 is slidably connected to the stator 202, and at least a portion of the rotor 201 is disposed within the stator 202. The rotor 201 is connected to the first circuit board 104 via a first connecting assembly 301, and the stator 202 is connected to the second circuit board 105 via a second connecting assembly 302.

[0072] In some embodiments, the slip ring 106 may be an electric slip ring, a lubricating ring, a fluid slip ring or other types, which are not limited here.

[0073] In some embodiments, the slip ring 106 further includes a conductive ring and a conductive brush, through which the first connecting component 301 is connected to the second connecting component 302. The conductive ring and the conductive brush ensure that when the first connecting component 301 and the rotor 201 rotate while the stator 202 and the second connecting component 302 are stationary, the conductive brush rotates around the conductive ring, thereby preventing entanglement and folding at the connection between the first connecting component 301 and the second connecting component 302 within the slip ring 106.

[0074] In some embodiments, as Figure 6As shown, the first connecting component 301 includes a first connecting member 3011 and a second connecting member 3012.

The first connecting member 3011 and the second connecting member 3012 are passed through the shaft sleeve 107 and are respectively connected to the first circuit board 104.

[0075] Specifically, the first connecting member 3011 and the second connecting member 3012 are respectively connected to the first circuit board 104 through the first connecting terminals 401 .

[0079] It is worth noting that when the first wire, the second wire, and the third wire are connected to the seventh wire, the eighth wire, and the ninth wire, respectively, the first wire and the seventh wire are the same wire, the second wire and the eighth wire are the same wire, and the third wire and the ninth wire are the same wire; or, when the first wire, the second wire, and the third wire are connected to the tenth wire, the eleventh wire, and the twelfth wire, respectively, the first wire and the tenth wire are the same wire, the second wire and the eleventh wire are the same wire, and the third wire and the twelfth wire are the same wire. The same applies to other wires and will not be repeated here.

[0080] Different wires can be used to transmit different signals. For example, a first wire is used to transmit a USB signal, a second wire is used to transmit a CAN signal, and a third wire is used to transmit a CAN FD signal.

[0081] In some embodiments, the first conductor, the second conductor, and the third conductor are the same or different. For example, the first conductor, the second conductor, and the third conductor are all optical cables. For another example, the first conductor is an optical cable, and the second conductor and the third conductor are both data cables. For another example, the first conductor is an optical cable, the second conductor is a data cable, and the third conductor is a twisted pair. The same applies to other conductors and will not be described in detail here.

[0082] In some embodiments, the slip ring 106 further includes a conductive ring and a conductive brush, and the first connector 3011 is electrically connected to the third connector 3021 or the fourth connector 3022 through the conductive ring and the conductive brush; and the second connector 3012 is electrically connected to the fourth connector 3022 or the third connector 3021 through the conductive ring and the conductive brush.

[0083] Under the action of the conductive ring and the conductive brush, it can be ensured that when the first connecting member 3011, the second connecting member 3012 and the rotor 201 rotate and the third connecting member 3021, the fourth connecting member 3022 and the stator 202 are stationary, the connection between the first connecting member 3011 and the second connecting member 3012 and the corresponding third connecting member 3021 and the fourth connecting member 3022 in the slip ring 106 will not be entangled or folded.

[0084] Based on Figure 6 Or the slip ring 106 structure shown in FIG7, the first connecting member 3011 and the second connecting member 3012 are provided through the sleeve 107 to connect the rotor 201 and the first circuit board 104, the third connecting member 3021 and the fourth connecting member 3022 can be as shown in FIG7. Figure 8 The cross section of the motor shown is schematic Figure 1 Generally, the third connector 3021 and the fourth connector 3022 can be connected to the stator 202 and the second circuit board 105 by passing through different wire slots 109 in the motor housing 103. Alternatively, the third connector 3021 and the fourth connector 3022 can be connected to the stator 202 and the second circuit board 105. Figure 9 The cross section of the motor shown is schematic Figure 1 Generally, the stator 202 and the second circuit board 105 are connected by passing through the same wire slot 109 in the motor housing 103.

[0085] See also Figure 10 , Figure 10 It is a schematic structural diagram of an electronic device in some embodiments of the present application. The electronic device 100 includes the motor 10 described in any of the above embodiments, which will not be described in detail here.

[0086] In some embodiments, the electronic device 100 may be a car, a smart air conditioner, a fan, a computer or others, which is not limited here.

[0087] In summary, the motor 10 provided in some embodiments of the present application arranges the slip ring 106 outside the motor housing 103. When the first circuit board 104 rotates, the rotor 201 and the first connecting component 301 in the slip ring 106 rotate together, while the stator 202 and the second connecting component 302 in the slip ring 106 are stationary. This can prevent the first connecting component 301 and the second connecting component 302 from being entangled and / or folded, thereby ensuring the continuity and stability of signal transmission.

[0088] In addition, the first connection component 301 and the second connection component 302 include a plurality of wires, and different signals can be transmitted simultaneously through different wires.
