[0034] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention.
[0035] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.
[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.
[0037] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0038] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0039] According to one embodiment of the present application, a conductive device is provided. Figures 1 to 6As shown, the conductive device comprises: a plurality of conductive mechanisms 1, which are suitable for being arranged at intervals along the circumference of the conductive member. The conductive mechanism 1 is suitable for installing a conductive member 11, and the conductive member 11 is suitable for being electrically connected to the conductive member, that is, the conductive member 11 contacts the conductive member to achieve conduction.
[0040] In this example, the conductive device includes a plurality of conductive mechanisms 1, which are arranged at intervals along the circumference of the conductive member, and there is a gap between two adjacent conductive mechanisms 1, so as to avoid blocking the oil circuit.
[0041] The conductive part may be a motor shaft 3. The shaft voltage induced on the motor shaft 3 will break through the bearing oil film, causing bearing damage. By sleeved with a conductive device on the motor shaft 3, the current on the motor shaft 3 can be extracted to reduce the shaft voltage. The conductive device of the present application includes a plurality of conductive mechanisms 1, which are in contact with the motor shaft 3 and the motor housing, and are used to extract the current of the motor shaft 3. The plurality of conductive mechanisms 1 are arranged at intervals along the circumference of the motor shaft 3, that is, there is a gap between two adjacent conductive mechanisms 1, which is conducive to the smooth flow of the oil path of the motor shaft 3 and avoids oil path blockage.
[0042] like Figure 1 As shown, in this example, five, six or seven conductive mechanisms 1 can be provided, and the plurality of conductive mechanisms 1 are evenly spaced along the circumference of the motor shaft 3. The number of conductive mechanisms 1 can be determined by those skilled in the art according to actual conditions, for example, it can be set according to the diameter of the motor shaft 3, and is not specifically limited here.
[0043] In an example, the conductive device further includes a second mounting structure 2 , and the conductive mechanism 1 is disposed on the second mounting structure 2 .
[0044] In this example, the conductive mechanism 1 is fixedly connected to the second mounting structure 2, the conductive mechanism 1 contacts the motor shaft 3, the conductive mechanism 1 is fixedly connected to the second mounting structure 2, the conductive mechanism 1 can be connected to the motor housing through the second mounting structure 2, and the motor housing is grounded. Thus, electricity can be conducted through the conductive mechanism 1 and the second mounting structure 2.
[0045] For example, in one example, Figure 2 As shown, the second mounting structure 2 includes a mounting ring, and a plurality of the conductive mechanisms 1 are arranged on the mounting ring along the circumference of the mounting ring.
[0046] like Figure 2As shown, the second mounting structure 2 can be a mounting ring, that is, a ring-mounted structure, such as a circular ring structure. The conductive structure is connected to the inner wall of the mounting ring at intervals along the circumference of the mounting ring. One end of each conductive mechanism 1 away from the inner wall of the mounting ring contacts the motor shaft 3. During assembly, multiple conductive mechanisms 1 are mounted on the mounting ring, and the mounting ring can simultaneously sleeve multiple conductive mechanisms 1 on the motor shaft 1 and install them on the motor housing, thereby improving installation efficiency.
[0047] Of course, the second mounting structure 2 may also be a metal conductive structure such as a mounting plate or a mounting rod, and the conductive mechanism 1 may be connected to the motor housing through the second mounting structure 2. For example, the conductive mechanism 1 may be connected to the second mounting structure 2 through fasteners such as bolts or screws, and the second mounting structure 2 may be connected to the motor housing through fasteners such as bolts or screws.
[0048] Alternatively, the motor housing may be used as the second mounting structure 2. That is, the conductive mechanism 1 may be directly fixedly connected to the motor housing by means of screws or rivets. Regarding the connection method of the conductive mechanism 1, those skilled in the art may determine it according to actual conditions, and no specific limitation is made here.
[0049] In an example, Figure 2 As shown, the inner wall of the mounting ring is provided with a clamping portion 21 , and the conductive mechanism 1 is clamped to the mounting ring via the clamping portion 21 .
[0050] like Figure 2 As shown, the inner wall of the mounting ring is provided with a clamping portion 21 for clamping the conductive mechanism 1. There are multiple clamping portions 21 to clamp and fix multiple conductive mechanisms 1. Each clamping portion 21 includes two clamping columns arranged at intervals, and the conductive mechanism 1 is clamped between the two clamping columns.
[0051] For example, the clamping column can be an elastic column, on which a clamping hook is provided, and clamping grooves are provided on the corresponding two sides of the conductive mechanism 1. The clamping hook is clamped in the clamping groove, so that the conductive mechanism 1 can be clamped and fixed to the mounting ring.
[0052] In this example, one end of the clamping column is connected to the inner wall of the mounting ring, and the other end extends toward the center of the mounting ring. There is an installation gap between the two clamping columns, and the conductive mechanism 1 is arranged in the installation gap, and the two ends of the conductive mechanism can be respectively clamped to the clamping columns on both sides. For example, the clamping column can be integrally formed with the inner wall of the mounting ring. Alternatively, the clamping column can also be fixedly connected to the mounting ring by fasteners such as screws or bolts. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.
[0053] Of course, the conductive mechanism 1 can also be fixedly connected to the mounting ring by other means. For example, the conductive mechanism 1 can also be fixedly connected to the mounting ring by fasteners such as screws or bolts. Alternatively, the conductive mechanism 1 can also be fixedly connected to the mounting ring by welding, etc. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.
[0054] In an example, Figures 1 to 3 As shown, the conductive mechanism 1 comprises a first mounting structure 12, a conductive member 11 is mounted on the first mounting structure 12, and at least one end of the conductive member 11 extends out of the first mounting structure 12 to contact the conductive member.
[0055] like Figures 1 to 3 As shown, in this example, the conductive member 11 is connected to the first mounting structure 12, and one end of the conductive member 11 extends out of the first mounting structure 12 so as to be in contact with the conductive member to be conducted. For example, the conductive member to be conducted is the motor shaft 3, and the plurality of conductive mechanisms 1 are arranged around the outer periphery of the motor shaft 3, and one end of the conductive member 11 extends out of the second mounting mechanism and toward the motor shaft 3.
[0056] In this example, one end of the conductive member 11 is in interference contact with the inner wall of the motor shaft 3. That is, the conductive member 11 is set longer so that the conductive member 11 can abut against the inner wall of the rotating shaft, and the conductive member 11 will have a certain deformation to improve the reliability of the conductive member 11 contacting the outer wall of the motor shaft 3.
[0057] The first mounting structure 12 may be made of a conductive metal material such as copper, nickel, iron, aluminum or alloys thereof, etc. Those skilled in the art may determine the material according to actual conditions, and no specific limitation is made here.
[0058] like Figure 1 As shown, in this example, the first mounting structure 12 can be arranged in a fan shape, and a plurality of first mounting structures 12 in a fan shape are arranged at intervals along the circumference of the motor shaft 3. By arranging the first mounting structure 12 in a fan shape, the extension length of each conductive member 11 can be made consistent, thereby facilitating the assembly of the conductive mechanism 1.
[0059] Of course, the first mounting structure 12 may also be in other shapes. For example, the first mounting structure 12 may also be set to be square, etc. Those skilled in the art may determine it according to actual conditions, for example, according to the shape of the conductive member to be conducted, or according to the installation form of the conductive mechanism 1, and no specific limitation is made here.
[0060] In an example, Figures 3 to 6As shown, the conductive mechanism includes a first mounting member 121 and a second mounting member 122 , and the conductive member 11 is partially disposed between the first mounting member 121 and the second mounting member 122 . The first mounting member 121 and the second mounting member 122 are suitable for clamping the conductive member 11 .
[0061] like Figures 3 to 6 As shown, in this example, the first mounting member 121 and the second mounting member 122 constitute the first mounting structure 12, and the conductive member 11 is arranged on the first mounting structure 12. The first mounting member 121 and the second mounting member 122 have the same shape. For example, the first mounting member 121 and the second mounting member 122 are both fan-shaped, the first mounting member 121 and the second mounting member 122 are clamped on the conductive member 11, and one end of the conductive member 11 protrudes from the first mounting member 121 and the second mounting member 122.
[0062] like Figure 4 indivual Figure 5 As shown, in this example, one of the first mounting member 121 and the second mounting member 122 is provided with a connecting portion 1212, and the other is provided with a matching portion 1222 matched with the connecting portion 1212. The connecting portion 1212 may be a riveting column, and the matching portion 1222 may be a riveting hole. The riveting column may be riveted into the riveting hole to connect the first mounting member 121 and the second mounting member 122 as a whole.
[0063] The first mounting member 121 may be provided with a plurality of riveting columns. The second mounting member 122 may be provided with a plurality of riveting holes correspondingly to improve the stability of the connection. For example, the first mounting member 121 may be provided with two riveting columns, and the two riveting columns may be provided on opposite sides of the first mounting member 121, respectively.
[0064] Alternatively, the first mounting member 121 and the second mounting member 122 may also be fixedly connected by fasteners such as screws or bolts, etc., and those skilled in the art may determine this based on actual conditions, and no specific limitation is made herein.
[0065] Of course, the first mounting structure 12 can also be integrally formed, and the first mounting structure 12 is provided with a mounting hole, and the conductive member 11 is partially fixedly embedded in the mounting hole.
[0066] In an example, Figures 4 to 6 As shown, the first mounting member 121 is provided with a mounting groove 1211 , and the mounting groove 1211 is suitable for accommodating a portion of the conductive member 11 , and the second mounting member 122 is provided with a protrusion 1221 facing the mounting groove 1211 .
[0067] like Figures 4 to 6As shown, the first mounting member 121 is provided with a mounting groove 1211, and the conductive member 11 is partially disposed in the mounting groove 1211, so as to fix the conductive member 11. The second mounting member 122 is provided with a protrusion 1221 toward the mounting groove 1211. That is, the position of the protrusion 1221 corresponds to the position of the mounting groove 1211, and the conductive member 11 is disposed in the mounting groove 1211, and the protrusion 1221 can fix and press the conductive member 11 in the mounting groove 1211. By providing the mounting groove 1211 to cooperate with the protrusion 1221, the mounting accuracy and assembly efficiency can be improved.
[0068] In one example, the mounting groove 1211 extends to the side wall of the first mounting member 121 , and an opening is formed on the side wall of the first mounting member 121 , so that the conductive member 11 partially extends out of the opening.
[0069] One end of the mounting groove 1211 extends outward to the edge of the first mounting member 121, and an opening is formed on the side wall of the first mounting member 121, so that the conductive member 11 can partially extend out of the first mounting member 121. The protrusion 1221 on the second mounting member 122 can fix and press the conductive member 11 into the mounting groove 1211.
[0070] In this example, the first mounting member 121 is provided with a plurality of mounting grooves 1211, and for each mounting groove 1211, the second mounting member 122 is correspondingly provided with a plurality of protrusions 1221 to improve the stability of pressing the conductive member 11. For example, for each mounting groove 1211, the second mounting member 122 is provided with two, three or four, etc., along the length direction of the mounting groove 1211. Those skilled in the art may determine according to actual conditions, and no specific limitation is made here.
[0071] In an example, Figures 1 to 3 As shown, the mounting groove 1211 is provided with a plurality of grooves, and the plurality of mounting grooves 1211 are arranged at intervals on the first mounting structure 12. A conductive member 11 is arranged in each mounting groove 1211. The number of the mounting grooves 1211 is less than or equal to 5. This can avoid the first mounting member 121 and the second mounting member 122 being loosely connected due to the excessive number of conductive members 11, and the conductive members 11 being too tight will also affect the patency of the oil passage.
[0072] Furthermore, there is a gap between adjacent conductive members 11 to prevent oil from impacting the conductive members 11. An oil film is formed between the ends of the conductive members 11 and the motor shaft 3, which cannot effectively contact the motor shaft 3, affecting the conductive effect of the conductive members 11, thereby failing to effectively reduce the shaft voltage.
[0073] In one example, the conductive member 11 includes conductive fibers, which include a core layer, a metal layer, and a polymer resin layer from the inside to the outside. A plurality of conductive fibers are bundled together to form the conductive member 11 .
[0074] The core layer of the conductive fiber is carbon fiber filament. Carbon fiber has excellent conductivity, and carbon fiber is a material with high strength, high hardness and high elastic modulus, which makes carbon fiber have good wear resistance; carbon fiber also has low density, which reduces the generation of friction and wear; carbon fiber also has good high temperature performance, suitable for use in high power motors in high temperature environments. This makes the conductive fiber bundle have good wear durability reliability when it is in interference contact with the motor shaft 3.
[0075] The middle layer is a metal layer, which has a better conductive effect. The high-frequency induced shaft current has a skin effect, that is, it is concentrated in a thin layer on the surface of the conductor. The closer to the conductor surface, the greater the current density, and the current inside the conductor is actually smaller. This allows the conductive fiber bundle to effectively guide the shaft voltage and shaft current when it is in interference contact with the motor shaft 3, and has good bearing protection. The metal layer includes copper, pure nickel, pure gold, pure silver, pure iron, pure zinc, pure aluminum, and one or more alloys thereof, as well as one or more layers of metal, and the mass fraction of the metal layer is 20% to 80%.
[0076] The outer layer is a polymer resin layer, and the bundling treatment increases the direct bonding of the fiber monofilaments to achieve a bundling effect, and increases the stiffness of the fiber bundle to achieve a surface oil-repellent effect. The fiber bundle diameter is controllable and can match the split-type conductive device fiber bundle mounting slot 1211. The split-type conductive device can be formed by a mold, which has low cost and high production efficiency. The polymer resin layer can be one of epoxy resin, polyacrylate, polyurethane, polyphenylene ether ketone, polyamide, polyimide, and phenoxy resin, and the mass fraction of the polymer resin layer is 0.5wt% to 3wt%.
[0077] In this example, the preparation process of the conductive fiber is: firstly roughen the surface of the original carbon fiber bundle, for example, by soaking it in acetone or acidic or alkaline liquid at room temperature, then metallize the surface by electroplating or chemical plating, place it in a resin slurry tank after cleaning, and finally pull it out from a mold hole of a specific diameter to obtain a bundled conductive fiber bundle with the required diameter tightened.
[0078] Among them, the resin slurry is prepared by dissolving epoxy resin, polyacrylate, polyurethane, etc. in organic solvents such as ethanol and acetone. A thin layer of resin is coated on the surface of the carbon fiber through the volatilization of the solvent, which increases the direct adhesion of the fiber filaments to each other to achieve a bundling effect, and increases the stiffness of the fiber bundle to achieve a surface oil-repellent effect.
[0079] According to another embodiment of the present application, a conductive device is provided, which includes a plurality of conductive mechanisms 1, each of which includes a conductive member 11, wherein the plurality of conductive mechanisms 1 are adapted to be spaced apart along the circumference of the member to be conductive, and the conductive member 11 is adapted to contact the member to be conductive.
[0080] In this example, the conductive device includes a plurality of conductive mechanisms 1, which are arranged at intervals along the circumference of the conductive member, and the conductive member 11 contacts the surface of the conductive member to achieve conduction. There is a gap between two adjacent conductive mechanisms 1 of the conductive device of the present application, so as to avoid blocking the oil circuit.
[0081] According to another embodiment of the present application, a motor is provided, which includes the conductive device of the above embodiment.
[0082] In an example, Figure 1 and Figure 2 As shown, the motor includes a motor shaft 3, and the conductive device includes a plurality of conductive mechanisms 1, and the plurality of conductive mechanisms 1 are arranged at intervals along the circumference of the motor shaft 3. By sleeved with the conductive device on the motor shaft 3, the current on the motor shaft 3 can be extracted to reduce the shaft voltage. The conductive device of the present application includes a plurality of conductive mechanisms 1, and the conductive mechanism 1 is in contact with the motor shaft 3 and the motor housing, and is used to extract the current of the motor shaft 3. The plurality of conductive mechanisms 1 are arranged at intervals along the circumference of the motor shaft 3, that is, there is a gap between two adjacent conductive mechanisms 1, which is conducive to the unblocked oil path of the motor shaft 3 and avoids oil path blockage.
[0083] In an example, Figure 1 and Figure 2 As shown, along the radial section of the motor shaft 3, the area of the gap between the outer diameter of the motor shaft 3 and the outer diameter of the conductive device is set to S1, and the area of all the conductive mechanisms 1 is set to S2, satisfying: 0.2S2≤S1≤0.8S2.
[0084] Figure 1 and Figure 2 It is a radial cross section along the motor shaft 3. The area of the gap between the outer diameter of the motor shaft 3 and the outer diameter of the conductive device is set to S1, that is, the area of the gap between the outer diameter of the motor shaft 3 and the inner wall of the mounting ring is S1. The cross-sectional area of all conductive mechanisms 1 is S2. Then it satisfies that 0.2S2≤S1≤0.8S2. Through this setting, the spacing of the conductive devices can be sufficient to avoid blocking the oil circuit or the oil-repelling effect is not obvious, and it can also ensure that the number of conductive mechanisms 1 is sufficient so that the conductive device has good conductive performance.
[0085] For example, six conductive mechanisms 1 are provided, and S1=0.3S2. Alternatively, S1 may be equal to 0.2S2, 0.5S2 or 0.8S2, etc. Those skilled in the art may determine the method according to actual conditions, and no specific limitation is made here.
[0086] In this example, the motor can be used in electrical equipment such as vehicles, or mechanical equipment such as machine tools. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.
[0087] According to another embodiment of the present application, an electric device is provided, which includes the motor of the above embodiment.
[0088] In this example, the electrical equipment includes the motor of the above embodiment, the motor includes a motor shaft 3, the conductive device includes a plurality of conductive mechanisms 1, and the plurality of conductive mechanisms 1 are arranged at intervals along the circumference of the motor shaft 3. By sleeved with the conductive device on the motor shaft 3, the current on the motor shaft 3 can be extracted to reduce the shaft voltage. The conductive device of the present application includes a plurality of conductive mechanisms 1, the conductive mechanism 1 is in contact with the motor shaft 3 and the motor housing, and is used to extract the current of the motor shaft 3. The plurality of conductive mechanisms 1 are arranged at intervals along the circumference of the motor shaft 3, that is, there is a gap between two adjacent conductive mechanisms 1, which is conducive to the unblocked oil path of the motor shaft 3 and avoids oil path blockage.
[0089] Of course, the electrical equipment of this embodiment also includes at least all the beneficial effects of the above embodiments, which will not be described in detail here.
[0090] The electric device of the present application may be a vehicle, such as a new energy vehicle, or may be other electric devices that require the use of the motor of the present application. Those skilled in the art may determine the method according to the actual situation, and no specific limitation is made here.
[0091] The above embodiments focus on the differences between the various embodiments.

Considering the simplicity of the text, they will not be repeated here.
