Description

Technical Field

[0001] This application relates to the field of vehicles, and more particularly to an electric motor and a vehicle. Background Technology

[0002] The electric current generated in the motor shaft of a vehicle motor will corrode the motor bearing, causing noise during operation or even causing the motor bearing to seize up, which seriously affects the service life of the motor and the driving safety of the vehicle.

[0003] Existing motors use conductive rings mounted on the motor shaft, with conductors, such as conductive fibers, installed on the conductive rings. The conductive fibers guide the current from the motor shaft to the conductive rings, which then guide the current to the motor housing. This effectively prevents the motor bearings on the motor shaft from being subjected to excessive current, thus preventing corrosion of the motor bearings.

[0004] Existing conductive fibers are installed on conductive rings by press fitting. During the press fitting process, the conductive ring is easily deformed, which affects the assembly of the conductive ring and changes the installation position of the conductive fibers, thus affecting the conductivity of the conductive fibers and conductive ring. Utility Model Content

[0005] This application provides an electric motor and a vehicle to solve the technical problem that the conductive ring is easily deformed when the conductive fiber is installed on the conductive ring.

[0006] A first aspect of this application provides a motor, including:

[0007] A housing, wherein a conductive ring is provided on the housing, and a plurality of mounting grooves are provided on the conductive ring;

[0008] The motor shaft passes through the conductive ring;

[0009] Multiple conductive components are arranged one-to-one in each of the mounting slots;

[0010] Multiple conductors, one end of each conductor is inserted into each of the conductive components, and the other end of each conductor extends out of the conductive component and abuts against the motor shaft.

[0011] In one possible implementation, each of the mounting slots is located on the same side of the conductive ring, and the mounting slots are spaced apart along the circumference of the conductive ring.

[0012] In one possible implementation, the extending direction of the mounting groove is consistent with the radial direction of the conductive ring, and the mounting groove includes a first limiting groove segment, an abutment groove segment, and a second limiting groove segment connected in sequence along the extending direction. The conductive component includes a first pipe segment, a second pipe segment, and a third pipe segment connected in sequence. The first pipe segment is disposed within the first limiting groove segment, and the first limiting groove segment is used to restrict the movement of the first pipe segment along the extending direction of the first limiting groove segment. The second pipe segment abuts within the abutment groove segment. The third pipe segment is disposed within the second limiting groove segment, and the second limiting groove segment is used to restrict the movement of the third pipe segment along the extending direction of the second limiting groove segment.

[0013] In one possible implementation, the outer diameters of the first pipe segment and the third pipe segment are both larger than the outer diameter of the second pipe segment, the first limiting groove segment cooperates with the first pipe segment, the abutting groove segment cooperates with the second pipe segment, and the second limiting groove segment cooperates with the third pipe segment.

[0014] In one possible implementation, the outer diameter of the first pipe segment gradually increases in the direction away from the second pipe segment, and the outer diameter of the third pipe segment gradually increases in the direction away from the second pipe segment.

[0015] Furthermore, the inner diameter of the end of the first pipe segment away from the second pipe segment is greater than the inner diameter of the end of the first pipe segment closer to the second pipe segment, and the inner diameter of the end of the third pipe segment away from the second pipe segment is greater than the inner diameter of the end of the third pipe segment closer to the second pipe segment.

[0016] In one possible implementation, a conductive element fixing member is also included, wherein each of the conductive elements is fixedly connected to the conductive ring through the conductive element fixing member.

[0017] In one possible implementation, the conductive component fixing member is a ring, which covers the surface of the conductive ring. The side of the ring facing the conductive ring has a plurality of fixing grooves, and each fixing groove corresponds to each mounting groove. The fixing grooves and the mounting grooves form a mounting cavity, and the conductive component is located in the mounting cavity and cooperates with the mounting cavity.

[0018] In one possible implementation, the housing is integrally formed with the conductive ring.

[0019] In one possible implementation, the conductive ring is provided with at least one first positioning hole, and the circular ring is provided with at least one second positioning hole, and each of the first positioning holes and each of the second positioning holes are connected in a one-to-one correspondence.

[0020] A second aspect of this application provides a vehicle, including a vehicle body and the aforementioned motor, the motor being disposed on the vehicle body.

[0021] This application provides an electric motor and vehicle. The motor includes a housing, a motor shaft, multiple conductive components, and multiple conductive bodies. A conductive ring with multiple mounting slots is provided on the housing. The motor shaft passes through the conductive ring. Each conductive component is correspondingly positioned in its respective mounting slot. One end of each conductive body passes through its corresponding conductive component, and the other end of each conductive body extends out of the conductive component and abuts against the motor shaft. In this application, the conductive bodies are inserted into the conductive components before being installed in the mounting slots of the conductive ring. This avoids directly pressing the conductive bodies onto the conductive ring, thus preventing deformation of the conductive ring caused by pressing. The electric motor only requires installing the conductive components into the mounting slots of the conductive ring, preventing the conductive ring from being subjected to excessive impact force and deformation caused by installing the conductive bodies. This solves the technical problem of existing conductive bodies easily deforming the conductive ring when installed, making it less prone to deformation during installation. This improves the assembly accuracy and effect of the conductive ring, prevents changes in the installation position of the conductive bodies, and ensures the conductivity of the conductive fibers and the conductive ring.

Detailed Implementation

[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0046] The electric current generated in the motor shaft of a vehicle motor will corrode the motor bearing, causing noise during operation or even causing the motor bearing to seize up, which seriously affects the service life of the motor and the driving safety of the vehicle.

[0047] Existing motors use conductive rings mounted on the motor shaft, with conductors, such as conductive fibers, installed on the conductive rings. The conductive fibers guide the current from the motor shaft to the conductive rings, which then guide the current to the motor housing. This effectively prevents the motor bearings on the motor shaft from being subjected to excessive current, thus preventing corrosion of the motor bearings.

[0048] Existing conductive fibers are installed on conductive rings by press fitting. During the press fitting process, the conductive ring is easily deformed, which affects the assembly of the conductive ring and changes the installation position of the conductive fibers, thus affecting the conductivity of the conductive fibers and conductive ring.

[0049] To address the technical problem that existing conductive fibers easily deform when mounted on conductive rings, this application proposes a motor and vehicle. The motor includes a housing, a motor shaft, multiple conductive components, and multiple conductive bodies. The housing has a conductive ring with multiple mounting slots. The motor shaft passes through the conductive ring. Each conductive component is correspondingly positioned in its respective mounting slot. One end of each conductive body passes through its corresponding conductive component, and the other end of each conductive body extends out of its conductive component and abuts against the motor shaft.

[0050] The motor of this application has a conductor inserted inside a conductive element, which is then installed in the mounting groove of a conductive ring. This avoids directly pressing the conductor onto the conductive ring, thus preventing deformation of the conductive ring caused by pressing. The motor of this application only needs to install the conductive element in the mounting groove of the conductive ring, thereby avoiding the conductive ring being subjected to large impact pressure and deformation caused by installing the conductor. This solves the technical problem that existing conductor installation on conductive rings easily leads to deformation, making it less likely for the conductive ring to deform when the conductor is installed on it. This improves the assembly accuracy and effect of the conductive ring, prevents changes in the installation position of the conductor, and ensures the conductivity of the conductive fiber and the conductive ring.

[0051] The technical solution of the application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0053] In the embodiments of this application, reference is made to Figure 1 , Figure 3 and Figure 5 As shown, an embodiment of this application provides an electric motor, including a housing, a motor shaft, a plurality of conductive elements 410 and a plurality of conductive bodies 420.

[0054] The housing 100 is provided with a conductive ring 200, and the conductive ring 200 is provided with multiple mounting grooves 300.

[0055] The motor shaft passes through the conductive ring 200.

[0056] Each conductive component 410 is installed in a corresponding mounting slot 300.

[0057] One end of each conductor 420 is inserted into each conductor 410, and the other end of each conductor 420 extends out of the conductor 410 and abuts against the motor shaft.

[0058] The motor housing 100 of this application is provided with a conductive ring 200. The conductive ring 200 can be integrally formed with the housing 100 or connected to it. The conductive ring 200 has a conductive function and can be made of conductive metal. The conductive ring 200 can transfer current to the housing 100. The motor shaft of the power supply motor passes through the conductive ring 200. The conductive ring 200 is provided with multiple mounting slots 300 for mounting conductive components 410.

[0059] The conductive component 400 includes a conductive element 410 and a conductive body 420. The conductive element 410 has a conductive function and can be a conductive tube, conductive sleeve, etc. In this embodiment, the conductive element 410 can be a metal tube.

[0060] The conductor 420 also has a conductive function. The conductor 420 can be a conductive fiber, such as carbon fiber. The conductor 420 is used to abut against the motor shaft of the motor. The conductor 420 is inserted into the conductive member 410, so that the current of the motor shaft can be guided into the conductive member 410. Because the conductive member 410 is installed in the mounting groove 300 on the conductive ring 200, the conductive member 410 can guide the current of the conductor 420 through the conductive ring 200 to the housing 100, thereby avoiding the motor bearing on the motor shaft from being subjected to a large current and effectively preventing the corrosion of the motor bearing.

[0061] It should be noted that the conductive component 410 can be snapped into the mounting groove 300 or fixed into the mounting groove 300 by other fasteners, and the conductive body 420 can be squeezed into the conductive component 410.

[0062] In this application, the motor has the conductor 420 inserted into the conductive element 410, and then the conductive element 410 installed in the mounting groove 300 of the conductive ring 200. This avoids directly pressing the conductor 420 onto the conductive ring 200, thus preventing deformation of the conductive ring 200 caused by pressing. The motor only requires the conductive element 410 to be installed in the mounting groove 300 of the conductive ring 200, thereby avoiding excessive impact pressure on the conductive ring 200 and preventing deformation caused by installing the conductor 420. This solves the technical problem that installing the conductor 420 onto the conductive ring 200 easily leads to deformation of the conductive ring 200. It makes it less likely for the conductive ring 200 to deform when the conductor 420 is installed, improving the assembly accuracy and effect of the conductive ring 200, preventing changes in the installation position of the conductor 420, and ensuring the conductivity of the conductive fiber and the conductive ring 200.

[0063] In some embodiments, each mounting groove 300 is located on the same side of the conductive ring 200, and each mounting groove 300 is distributed at intervals along the circumference of the conductive ring 200.

[0064] In this embodiment, by having each mounting groove 300 located on the same side of the conductive ring 200, it is ensured that each conductive element 410 can be mounted on the same plane, thereby enabling each conductive body 420 to be located on the same plane.

[0065] Furthermore, the mounting grooves 300 are evenly spaced along the circumference of the conductive ring 200. This ensures that each conductor 420 is subjected to uniform force and conducts electricity uniformly.

[0066] In other embodiments, the extension direction of the mounting groove 300 is consistent with the radial direction of the conductive ring 200, and the mounting groove 300 includes a first limiting groove segment 310, an abutment groove segment 320 and a second limiting groove segment 330 connected in sequence along the extension direction. The conductive element 410 includes a first pipe segment 411, a second pipe segment 412 and a third pipe segment 413 connected in sequence. The first pipe segment 411 is disposed in the first limiting groove segment 310, and the first limiting groove segment 310 is used to restrict the movement of the first pipe segment 411 along the extension direction of the first limiting groove segment 310. The second pipe segment 412 abuts in the abutment groove segment 320. The third pipe segment 413 is disposed in the second limiting groove segment 330, and the second limiting groove segment 330 is used to restrict the movement of the third pipe segment 413 along the extension direction of the second limiting groove segment 330.

[0067] In this embodiment, the second pipe segment 412 is abutted into the abutting groove segment 320 to fix the conductive component 410. The first pipe segment 411 is restricted from moving along the extension direction of the first limiting groove segment 310 by the first limiting groove segment 310, and the third pipe segment 413 is restricted from moving along the extension direction of the second limiting groove segment 330 by the second limiting groove segment 330. This ensures that the conductive component 410 will not be displaced along the extension direction of the mounting groove 300, thereby ensuring that the conductive component 410 can be positioned in the mounting groove 300 and that the conductive component 410 will not be offset within the mounting groove 300, thus improving the stability of the fixing of the conductive component 410.

[0068] It should be noted that there are many ways to restrict the movement of the first pipe section 411 along the extension direction of the first limiting groove section 310 and the movement of the third pipe section 413 along the extension direction of the second limiting groove section 330. For example, by using limiting members and snap-fit ​​members, or by setting limiting parts in the first limiting groove section 310 and the second limiting groove section 330, or by setting limiting parts on the first pipe section 411 and the third pipe section 413.

[0069] In one embodiment, the outer diameters of the first pipe section 411 and the third pipe section 413 are both larger than the outer diameter of the second pipe section 412. The first limiting groove section 310 cooperates with the first pipe section 411, the abutting groove section 320 cooperates with the second pipe section 412, and the second limiting groove section 330 cooperates with the third pipe section 413.

[0070] In this embodiment, after the conductive component 410 is installed in the mounting groove 300, since the outer diameters of the first pipe segment 411 and the third pipe segment 413 are both larger than the outer diameter of the second pipe segment 412, and the first limiting groove segment 310 cooperates with the first pipe segment 411, the abutting groove segment 320 cooperates with the second pipe segment 412, and the second limiting groove segment 330 cooperates with the third pipe segment 413, the first pipe segment 411 will not move toward the abutting groove segment 320, and the third pipe segment 413 will not move toward the abutting groove segment 320. That is, the conductive component 410 will not be displaced along the extension direction of the mounting groove 300, thus ensuring the stability of the conductive component 410.

[0071] In one possible embodiment, the outer diameter of the first pipe segment 411 gradually increases in the direction away from the second pipe segment 412, and the outer diameter of the third pipe segment 413 gradually increases in the direction away from the second pipe segment 412.

[0072] In this embodiment, the first pipe segment 411 and the third pipe segment 413 form a frustum shape, thereby ensuring that the first pipe segment 411 will not move toward the abutting groove segment 320 and the third pipe segment 413 will not move toward the abutting groove segment 320.

[0073] In some embodiments, the inner diameter of the end of the first pipe segment 411 away from the second pipe segment 412 is larger than the inner diameter of the end of the first pipe segment 411 closer to the second pipe segment 412, and the inner diameter of the end of the third pipe segment 413 away from the second pipe segment 412 is larger than the inner diameter of the end of the third pipe segment 413 closer to the second pipe segment 412.

[0074] In this embodiment, since the inner diameter of the end of the first pipe segment 411 away from the second pipe segment 412 is larger than the inner diameter of the end of the first pipe segment 411 close to the second pipe segment 412, and the inner diameter of the end of the third pipe segment 413 away from the second pipe segment 412 is larger than the inner diameter of the end of the third pipe segment 413 close to the second pipe segment 412, the two ends of the conductive element 410 are flared to avoid wear on the conductive body 420 when the conductive body 420 is inserted into the conductive element 410.

[0075] Furthermore, the inner cross-section of the second tube segment 412 is rectangular or elliptical. This ensures that the second tube segment 412 can press the conductor 420 tightly, and the second tube segment 412 acts as a limiter for the conductor 420, ensuring that the conductor 420 does not fall out of the conductive component 410.

[0076] In other embodiments, a conductive element fixing member 500 is also included, and each conductive element 410 is fixedly connected to the conductive ring 200 through the conductive element fixing member 500.

[0077] In this embodiment, the conductive component fixing member 500 can be a welded component, that is, the conductive component 410 can be welded into the mounting groove 300 by the welded component, thereby further preventing the conductive component 410 from falling out of the mounting groove 300.

[0078] In some possible embodiments, the conductive element fixing member 500 is a ring, which covers the surface of the conductive ring 200. The side of the ring facing the conductive ring 200 is provided with a plurality of fixing grooves 510, and each fixing groove 510 corresponds to each mounting groove 300. The fixing grooves 510 and the mounting grooves 300 form a mounting cavity, and the conductive element 410 is located in the mounting cavity and cooperates with the mounting cavity.

[0079] In this embodiment, by installing the conductive element 410 in the mounting cavity formed by the fixing groove 510 and the mounting groove 300, the conductive element 410 is further prevented from detaching from the mounting groove 300, thus limiting and positioning the conductive element 410.

[0080] Furthermore, the conductive ring 200 is provided with at least one first positioning hole 600, and the ring is provided with at least one second positioning hole 700, and each first positioning hole 600 and each second positioning hole 700 are connected in a one-to-one correspondence.

[0081] In this embodiment, the engagement between the first positioning hole 600 and the second positioning hole 700 enables the ring to be quickly positioned on the conductive ring 200, thereby improving the installation efficiency and positioning accuracy of the ring.

[0082] Specifically, positioning pins, positioning bolts, etc. can be inserted into the first positioning hole 600 and the second positioning hole 700 to fix the ring onto the conductive ring 200.

[0083] It should be noted that positioning grooves, positioning blocks, positioning buckles, etc. can also be set to quickly position the ring on the conductive ring 200.

[0084] In another embodiment, the housing 100 and the conductive ring 200 are integrally formed.

[0085] In this embodiment, since the housing 100 and the conductive ring 200 are integrally formed, that is, the conductive ring 200 is integrated on the housing 100, the conductive ring 200 is eliminated, thereby reducing the number of parts, reducing production costs, and also eliminating the step of installing the conductive ring 200. This means that during assembly, there is no need to consider the fit between the conductive ring 200 and the housing 100, avoiding deformation of the conductive ring 200, thereby improving assembly efficiency and assembly accuracy.

[0086] A second aspect of this application provides a vehicle, including a vehicle body and a motor as described in the above embodiments, the motor being mounted on the vehicle body.

[0087] The vehicle body of this application is equipped with a motor according to this embodiment. The motor includes a housing, multiple conductive elements 410 and multiple conductive bodies 420. A conductive ring 200 is provided on the housing 100 for the motor shaft of the power supply to pass through. Multiple mounting grooves 300 are provided on the conductive ring 200. Each conductive element 410 is disposed in a corresponding mounting groove 300. One end of each conductive body 420 is disposed in a corresponding conductive element 410, and the other end of each conductive body 420 extends out of the conductive element 410 to abut against the motor shaft. In this application, the motor has the conductor 420 inserted into the conductive element 410, and then the conductive element 410 installed in the mounting groove 300 of the conductive ring 200. This avoids directly pressing the conductor 420 onto the conductive ring 200, thus preventing deformation of the conductive ring 200 caused by pressing the conductor 420. The motor of this vehicle only needs to install the conductive element 410 into the mounting groove 300 of the conductive ring 200, thereby avoiding the conductive ring 200 being subjected to large impact pressure and avoiding deformation of the conductive ring 200 caused by installing the conductor 420. This solves the technical problem that the installation of the conductor 420 onto the conductive ring 200 easily leads to deformation of the conductive ring 200. It makes it less likely for the conductive ring 200 to deform when the conductor 420 is installed onto it, improving the assembly accuracy and assembly effect of the conductive ring 200, preventing changes in the installation position of the conductor 420, and ensuring the conductivity of the conductive fiber and the conductive ring 200.
