[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 structure is provided. Figures 1 to 4 As shown, the conductive structure includes a first mounting member 3 and a second mounting member 2. The first mounting member 3 is provided with a mounting groove 32. The second mounting member 2 is provided with a pressing portion 22, and the pressing portion 22 includes a protrusion facing the mounting groove 32. The mounting groove 32 is suitable for accommodating the conductive member 1, and the protrusion is suitable for pressing the conductive member 1 into the mounting groove 32.

[0040] The conductive structure includes a first mounting member 3 and a second mounting member 2. The first mounting member 3 and the second mounting member 2 are split structures. The first mounting member 3 and the second mounting member 2 can be formed by a mold, so that the overall processing of the conductive structure is simpler, which can improve production efficiency and reduce production costs. In addition, the pressing portion 22 on the second mounting member 2 includes a protrusion, which abuts against the conductive member 1 through the protrusion, thereby improving the stability of the installation of the conductive member 1 and thus improving the conductive performance.

[0041] For example, the shaft voltage induced on the motor shaft 4 and the shaft current generated by the shaft voltage accumulation will break through the bearing oil film, which may easily cause abnormal noise or even damage the motor. By connecting the conductive structure of the present application to the conductive member, the shaft current on the shaft 4 can be guided out, effectively reducing the motor shaft voltage.

[0042] In this example, the first mounting member 3 and the second mounting member 2 can be made of conductive metal materials such as copper, nickel, iron, aluminum or their alloys. The clamping portion 22 on the second mounting member 2 abuts against the conductive member 1 to fix the conductive member 1 to the first mounting member 3 and the second mounting member 2. The first mounting member 3 and the second mounting member 2 are connected to the motor housing through a metal rod, and the housing is grounded. One end of the conductive member 1 extends out of the first mounting member 3 to facilitate contact with the surface of the rotating shaft 4, so that the current on the motor rotating shaft 4 can be conducted to the ground to effectively reduce the motor shaft voltage. Of course, the conductive structure of the present application can also be used for conductive operations of other equipment, and those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0043] The first mounting member 3 and the second mounting member 2 can be fixedly connected to the metal rod by two or three hexagonal nuts, or can be connected to the metal rod by sleeve fixing, and one end of the metal rod is connected to the motor housing.

[0044] The outer diameters of the first mounting member 3 and the second mounting member 2 can be set according to the size of the motor shaft 4 , and those skilled in the art can determine the size according to actual conditions, and no specific limitation is made here.

[0045] In this example, the conductive member 1 is partially disposed on the mounting groove 32 , and one end of the conductive member 1 extends outward and can extend out of the first mounting member 3 so as to contact the surface of the motor shaft 4 .

[0046] like Figure 3 As shown, one end of the mounting groove 32 extends away from the center of the first mounting member 3 and forms an opening on the side wall of the first mounting member 3 .

[0047] like Figure 3 As shown, one end of the mounting groove 32 extends to the outside of the first mounting member 3 and forms an opening on the side wall of the first mounting member 3. The conductive member 1 is partially disposed in the mounting groove 32, and one end of the conductive member 1 can extend out of the first mounting member 3 from the opening.

[0048] In this example, the first mounting member 3 may be a circular ring structure, one end of the mounting groove 32 extends outward and forms an opening with the outer wall of the first mounting member 3 , while the other end of the mounting groove 32 extends inward and forms an opening with the inner wall of the first mounting member 3 .

[0049] Of course, the specific configuration of the mounting groove 32 can be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0050] In this example, the pressing portion 22 includes a plurality of protrusions facing the mounting groove 32. There are a plurality of protrusions, which can be spaced apart along the length direction of the mounting groove 32, so that each protrusion can abut against the conductive member 1, effectively increasing the contact area between the second mounting member 2 and the conductive member 1, and improving the stability of the conductive member 1.

[0051] like Figure 1 As shown, one end of the clamping portion 22 extends toward the inner side of the second mounting member 2 and has a gap with the inner wall of the second mounting member 2. The other end of the clamping portion 22 extends toward the outer side of the second mounting member 2 and can be flush with the outer wall of the second mounting member 2. The first mounting member 3 and the second mounting member 2 are cylindrical, and the conductive member 1 is located on the extension line of the diameter of the first mounting member 3. That is, a plurality of protrusions can be arranged at intervals along the radial direction of the second mounting member 2. Among them, two, three, four or five protrusions can be arranged. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0052] In this example, the protrusion may be a cylindrical boss facing the installation groove 32, or other irregular structures, etc., as long as it can abut against the conductive member 1 and press the conductive member 1 against the installation groove 32. Those skilled in the art may determine according to actual conditions, and no specific limitation is made here.

[0053] In an example, Figure 1 and Figure 3As shown, a plurality of the mounting grooves 32 are provided, and the plurality of the mounting grooves 32 are arranged at intervals along the circumference of the first mounting member 3 , and a plurality of the pressing portions 22 are correspondingly provided on the second mounting member 2 .

[0054] like Figure 1 and Figure 3 As shown, a plurality of mounting grooves 32 are provided, and the plurality of mounting grooves 32 are arranged along the circumference of the first mounting member 3. A conductive member 1 is arranged in each mounting groove 32, and one end of each conductive member 1 can contact the surface of the rotating shaft 4 to improve the current transmission efficiency and transmission reliability. The second mounting member 2 is provided with a plurality of pressing portions 22 at corresponding intervals along the circumference. Each pressing portion 22 is arranged one-to-one with a mounting groove 32.

[0055] For example, the first mounting member 3 is a cylindrical structure, and the mounting groove 32 is located at one end of the first mounting member 3 along the axial direction. The plurality of conductive members 1 are evenly spaced around the circumference of the first mounting member 3. The second mounting member 2 is consistent in shape with the first mounting member 3. For example, the second mounting member 2 and the first mounting member 3 are both annular structures.

[0056] Among them, the number of the conductive members 1 can be 15, 20 or 25, etc., and those skilled in the art can determine it according to the actual situation, and no specific limitation is made here.

[0057] In an example, Figure 3 As shown, the mounting groove 32 is provided with a mounting groove 32 , and the conductive member 1 is partially disposed in the mounting groove 32 .

[0058] like Figure 3 As shown, the mounting groove 32 is provided with the mounting groove 32, and the conductive member 1 is partially arranged in the mounting groove 32, so as to fix the conductive member 1. That is, the position of the pressing portion 22 corresponds to the position of the mounting groove 32, the conductive member 1 is arranged in the mounting groove 32, and the pressing portion 22 can fix and press the conductive member 1 in the mounting groove 32. By providing the mounting groove 32 to cooperate with the pressing portion 22, the installation accuracy and assembly efficiency can be improved.

[0059] One end of the mounting groove 32 extends outward to the edge of the mounting groove 32 so that the conductive member 1 can extend out of the first mounting member 3. The pressing portion 22 on the second mounting member 2 can fix and press the conductive member 1 in the mounting groove 32.

[0060] In one example, the cross-sectional shape of the mounting groove 32 includes a U-shape or a trapezoidal shape or a combination of one or more shapes.

[0061] The cross-sectional shape of the mounting groove 32 may be a U-shaped structure or a trapezoidal structure, or may be a combination of multiple shapes.

[0062] For example, the conductive member 1 includes a plurality of conductive fibers, and the plurality of conductive fibers are arranged in the mounting groove 32. The cross section of the mounting groove 32 can be a combination of a U-shape and a trapezoid, which can ensure the bundling effect of the conductive member 1. That is, the inner side of the mounting groove 32 away from the opening can be set as a U-shaped structure, and a trapezoidal structure is set near the outer side. Of course, the specific structure of the mounting groove 32 can be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0063] In an example, Figures 1 to 4 As shown, one of the first mounting member 3 and the second mounting member 2 is provided with a connecting portion 33 , and the other is provided with a matching portion 21 matched with the connecting portion 33 .

[0064] like Figure 1 and Figure 3 As shown, in this example, the first mounting member 3 is provided with a connecting portion 33, and the second mounting member 2 is provided with a matching portion 21 that matches the connecting portion 33. The connecting portion 33 can be fixedly connected to the matching portion 21 to connect the first mounting member 3 to the second mounting member 2, so that the pressing portion 22 can press the conductive member 1 in the mounting groove 32 or in the mounting groove 32.

[0065] Of course, the connecting portion 33 may also be provided on the second mounting member 2, and the first mounting member 3 is provided with the matching portion 21. Those skilled in the art may determine according to actual conditions, and no specific limitation is made here.

[0066] In this example, the connecting portion 33 includes a rivet column 331, and the matching portion 21 includes a rivet hole 211. Figure 4 As shown, the connecting portion 33 may be a riveting column 331. Figure 2 As shown, the matching portion 21 may include a rivet hole 211. The rivet column 331 may be crimped into the rivet hole 211 to form a riveted connection. By riveting, the connection between the first mounting member 3 and the second mounting member 2 is more stable and reliable.

[0067] Among them, Figure 4 As shown, the rivet column 331 is in a state of being deformed by crimping, and one end has a convex structure outward. The rivet column 331 is a hollow column structure with a hole before crimping. One end of the rivet hole 211 has a sink 212 for accommodating the convex structure of the end of the rivet column 331 after deformation, so that the rivet column 331 can be fixedly connected to the rivet hole 211. Among them, a plurality of rivet columns 331 can be provided, and a plurality of rivet holes 211 are also provided correspondingly, so as to improve the stability of the connection between the first mounting member 3 and the second mounting member 2.

[0068] Of course, the first mounting member 3 and the second mounting member 2 can also be fixedly connected by other connection structures. For example, the connection portion 33 is a stud, the matching portion 21 is a screw hole, and the first mounting member 3 and the second mounting member 2 can be fixedly connected by screw connection. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0069] In an example, one of the first mounting member 3 and the second mounting member 2 is provided with a first positioning column 31 , and the other is provided with a first positioning hole 23 matched with the first positioning column 31 .

[0070] like Figure 1 and Figure 3 As shown, the first mounting member 3 is provided with a first positioning column 31. The second mounting member 2 is provided with a first positioning hole 23. The first positioning column 31 is provided in the mounting groove 32 and extends toward the first positioning hole 23. When the first mounting member 3 and the second mounting member 2 are assembled, the first positioning column 31 can be inserted into the first positioning hole 23 for positioning, and then the rivet column 331 is crimped into the rivet hole 211. By respectively providing the first positioning column 31 and the first positioning hole 23 on the first mounting member 3 and the second mounting member 2, the first mounting member 3 and the second mounting member 2 are conveniently positioned and installed.

[0071] Of course, the first positioning column 31 can also be provided on the second mounting member 2, and the first positioning hole 23 can be provided on the first mounting member 3. Alternatively, the first mounting member 3 is provided with the first positioning hole 23 and the first positioning column 31, respectively, and the second mounting member 2 is correspondingly provided with the first positioning column 31 and the first positioning hole 23. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0072] There may be a plurality of first positioning posts 31, which are arranged at intervals along the circumference of the first mounting member 3, or are evenly spaced. There are also a plurality of first positioning holes 23, and each first positioning post 31 can be inserted into a first positioning hole 23 to improve the positioning effect. For example, there may be two, three, or four first positioning posts 31, and those skilled in the art may determine this according to actual conditions, and no specific limitation is made here.

[0073] In this example, if Figure 3As shown, the second mounting member 2 is also provided with a second positioning hole 34. When the conductive structure is assembled, the second mounting member 2 is fixed to the lower mold of the jig through the second positioning hole 34, that is, the lower mold is provided with a second positioning column, and the second positioning column can be inserted into the second positioning hole 34 to fix the second mounting member 2. Then the conductive member 1 is placed in the mounting groove 32, and then the first positioning column 31 of the first mounting member 3 is inserted into the first positioning hole 23 of the second mounting member 2 to position the first mounting member 3 and the second mounting member 2, and the clamping part 22 can clamp the conductive member 1. Then start the crimping equipment to crimp the rivet column 331 on the first mounting member 3 into the rivet hole 211 so that the first mounting member 3 and the second mounting member 2 are riveted into a whole.

[0074] According to another embodiment of the present application, a conductive device is provided. Figure 1 and Figure 2 As shown, the conductive device includes a conductive member and the conductive structure of the above embodiment, and the conductive member is connected to the conductive structure.

[0075] In this example, the conductive member 1 is partially accommodated in the mounting groove 32 , one end of the conductive member 1 extends away from the center of the first mounting member 3 and protrudes out of the first mounting member 3 , and the protrusion abuts against the conductive member 1 to press the conductive member 1 into the mounting groove 32 .

[0076] The rotating shaft 4 can be set as a hollow structure, and the conductive device is arranged inside the rotating shaft 4. One end of the conductive member 1 extends away from the center of the first mounting member 3 and extends out of the first mounting member 3. So that one end of the conductive member 1 can contact the inner wall of the rotating shaft 4 to play a conductive role. By extending the conductive member 1 outward, the conductive member 1 can be arranged inside the rotating shaft 4, so as to reasonably utilize the installation space.

[0077] In one example, the conductive member 1 includes conductive fibers. The conductive fibers 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 1.

[0078] 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 4.

[0079] 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, 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%.

[0080] The outer layer is a polymer resin layer, and the bundling treatment increases the direct mutual adhesion of the fiber monofilaments to achieve the bundling effect, and increases the stiffness of the fiber bundle to achieve the surface oil-repellent effect. The diameter of the fiber bundle is controllable and can match the split conductive structure fiber bundle installation groove 32. The split conductive structure 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%.

[0081] 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.

[0082] 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.

[0083] According to another embodiment of the present application, a motor is provided, which includes the conductive device of the above embodiment.

[0084] In one example, the motor further includes a rotating shaft 4 , the conductive device is disposed inside the rotating shaft 4 , and one end of the conductive member 1 is in interference contact with an inner wall of the rotating shaft 4 .

[0085] The shaft voltage induced on the motor shaft 4 and the shaft current generated by the shaft voltage accumulation will break through the bearing oil film, which may easily cause abnormal noise or even damage the motor. By setting the shaft 4 hollow and setting the conductive device inside the shaft 4, the shaft current on the shaft 4 can be led out, effectively reducing the shaft voltage of the shaft 4.

[0086] One end of the conductive member 1 extends away from the center of the first mounting member 3 and extends out of the first mounting member 3. This allows one end of the conductive member 1 to contact the inner wall of the rotating shaft 4 to achieve a conductive effect. The conductive member 1 is in interference contact with the inner wall of the rotating shaft 4, that is, the conductive member 1 is arranged to be relatively long so that the conductive member 1 can abut against the inner wall of the rotating shaft 4, and the conductive member 1 will have a certain deformation to improve the reliability of the conductive member 1 contacting the inner wall of the rotating shaft 4.

[0087] According to another embodiment of the present application, an electrical device is provided. The electrical device includes the motor of the above embodiment. The motor includes the conductive device of the above embodiment, and the conductive device includes a first mounting member 3, a second mounting member 2 and a conductive member 1. The first mounting member 3 and the second mounting member 2 are split structures, so that the overall processing of the conductive device is simpler, and can be formed by a mold, which can improve production efficiency and reduce production costs. And the clamping portion 22 on the second mounting member 2 includes a plurality of protrusions, and the plurality of protrusions are respectively abutted against the conductive member 1, so that the contact area between the second mounting member 2 and the conductive member 1 can be increased, and the overall conductive performance of the conductive device can be improved.

[0088] The electrical equipment may be a vehicle, such as a new energy vehicle, etc. Those skilled in the art may determine the method according to actual conditions, and no specific limitation is made here.

[0089] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
