Description

Technical Field

[0001] This application relates to the field of conductive ring technology, specifically to a conductive block, a conductive ring, and a motor. Background Technology

[0002] Conductive rings typically involve multiple conductive blocks, each with a single conductive fiber bundle. The conductive ring achieves electrical connection by utilizing the conductive fibers (or bundles) on these blocks to make conductive contact with the sliding surface. Therefore, conductive rings are a key component for solving the problem of continuous and reliable transmission of electrical energy or signals between sliding contact devices. In other words, conductive rings are crucial bridges for achieving continuous transmission of electrical energy and signals between components (such as between rotating components, or between a rotating component and a stationary component). For example, the conductive ring inside a motor is a key device for achieving continuous and reliable transmission of electrical energy and signals within the motor.

[0003] However, existing conductive ring products cannot meet the conductive contact requirements of some applications, such as the requirement that conductive rings can flexibly change the conductive fibers to adapt to the contact area requirements of different applications.

[0047] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0048] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification.

[0050] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application.

In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0051] Additionally, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that practice can be carried out without these specific details.

[0052] The conductive block in the conductive ring achieves electrical connection through sliding friction contact between conductive fibers and the conductive surface, thus the conductive block is a component similar to an electric brush.

[0053] Existing conductive ring products typically use multiple conductive blocks, each designed with only a single bundle of conductive fibers. When the application requires a certain conductive contact area, such as a large area of ​​conductive fiber contact, the conductive ring cannot flexibly adapt to these application requirements. If the conductive ring design is redesigned, the design and production costs will increase, and the product cycle will also be significantly extended.

[0054] Therefore, through extensive research and improvement exploration of conductive ring products, a new conductive block structure was proposed. By optimizing and improving the structure of the conductive block, the conductive blocks in the conductive ring can be flexibly configured according to the needs of the application scenario, thereby realizing the flexible configuration of the conductive ring.

[0055] This application provides a conductive block technical solution: Reference Figure 1 The conductive block has been redesigned with a new structure, comprising a conductive support 10, fasteners 20, and multiple conductive brush modules 30. Each conductive brush module 30 has a new structure, including a conductive fixing block 301 (see [reference]). Figure 6 (Illustrative) and multiple conductive fiber bundles 302 (see diagram) Figure 6 (Illustrative diagram) Thus, a new conductive brush module 30 is obtained based on the improved structure, and different conductive ring products can be flexibly constructed by selecting different numbers of conductive brush modules 30. This enables flexible configuration of the conductive contact area of ​​the conductive ring product, thereby meeting the requirements of actual application scenarios for the conductive contact area of ​​the conductive ring product.

[0056] When a new conductive ring product needs to be constructed, it is only necessary to select and match multiple suitable conductive brush modules according to the actual application requirements for the conductive contact of the conductive ring product, without redesigning the conductive ring product. A new conductive ring product that meets the actual application requirements can be quickly assembled.

[0057] For example, if a large or small conductive contact area is required between the conductive ring and the sliding contact surface, simply select an appropriate number of conductive brush modules and re-fasten them to the conductive bracket to form a new conductive ring product, without having to redesign the conductive ring.

[0058] For example, when a planar or arcuate contact is required between the conductive ring and the sliding contact surface, simply select suitable conductive brush modules and re-secure them to the conductive support to form a new conductive ring product, without redesigning the conductive ring. For instance, multiple identical or different conductive brush modules can be selected and assembled so that the conductive fiber contact ends of each module together form a planar contact surface, creating a planar conductive connection with the sliding contact surface. Similarly, multiple identical or different conductive brush modules can be selected and assembled so that the conductive fiber contact ends of each module together form an arcuate contact surface, creating an arcuate conductive connection with the sliding contact surface. It should be noted that the identical or different conductive brush modules used to achieve the planar or arcuate contact surface can refer to partial or complete similarities or differences in shape, size, conductive fiber bundle, assembly position, etc. Specific examples can be found in the illustrations below, and will not be elaborated upon here.

[0059] In summary, when different specifications of conductive ring products are required, there is no need to redesign the conductive ring. Simply select multiple suitable conductive blocks and reassemble them to form a new conductive block, or select multiple suitable conductive brush modules to form a new conductive block. Then, adapt the new conductive block to the conductive ring product to obtain a new conductive ring product.

[0060] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0061] refer to Figures 1 to 6 This specification provides a conductive block, comprising: a conductive support 10, a fastener 20, and multiple conductive brush modules 30; wherein each conductive brush module 30 includes multiple conductive fiber bundles 302 and a conductive fixing block 301, one end of the conductive fiber bundle 302 is fixed in the conductive fixing block 301, and the other end of the conductive fiber bundle 302 serves as a sliding contact end; and the conductive fixing block 301 is provided with at least two fixing holes 303, so that the conductive brush module 30 is fastened to the conductive support 10 by the fastener 20 through the fixing holes 303.

[0062] In practice, the conductive brush module 30 is structured with multiple conductive fiber bundles 302 and conductive fixing blocks 301. By setting corresponding fixing holes 303 in the conductive fixing blocks 301, the conductive brush module 30 can be easily made universal, modular, and miniaturized. Thus, when there are different usage requirements for conductive ring products in actual applications, new conductive ring products can be flexibly obtained by simply selecting the appropriate conductive block (or conductive brush module). There is no need to spend a lot of manpower and resources to redesign and produce, which can quickly meet the usage requirements of conductive ring products in actual applications.

[0063] In practice, fastener 20 can be selected as rivets or bolts, which pass through multiple conductive brush modules and comb teeth to fasten them together.

[0064] It should be noted that the conductive support is equipped with a corresponding structure for fastening. Figure 1 The corresponding examples are for illustrative purposes only and should not constitute any limitation on this application.

[0065] In some examples, since the conductive bracket 10 is usually installed in the conductive ring product, the conductive bracket 10 can be designed as a universal structure and has several installation positions to facilitate the fasteners 20 to fasten and fix the conductive brush module 30. This not only facilitates the assembly of the conductive block in the conductive ring, but also allows multiple conductive brush modules to be flexibly adapted to the conductive block.

[0066] For example, if the conductive block is originally designed to fit 5 conductive brush modules 30, and it is required to fit 3 conductive brush modules 30, a universal conductive block can be quickly obtained by simply using the fastener 20 to adapt to the installation requirements of the conductive brush modules 30 in the conductive bracket 10, without affecting the installation of the conductive block in the conductive ring.

[0067] In some examples, by designing conductive brush modules 30 of various specifications, when different specifications of conductive block products are needed, it is only necessary to select the appropriate specifications of conductive brush modules 30 and assemble them into the conductive bracket 10 to quickly obtain new conductive block products (or new conductive ring products).

[0068] In summary, by selecting and matching conductive brackets 10 and conductive brush modules 30 of different specifications, new conductive block products can be quickly assembled, thereby obtaining new conductive ring products.

[0069] Therefore, when a new conductive ring product is needed, by reselecting suitable conductive brackets, conductive brush modules, etc., and reassembling them, a new conductive block can be quickly obtained to support the conductive contact requirements of the conductive ring product.

[0070] In some embodiments, the conductive fibers constituting the conductive fiber bundle 302 can be reliable flexible conductive fibers, such as carbon fibers with conductive coatings, composite or monomeric metal fibers, wear-resistant polymer composite fibers, carbon cloth, etc., so that the conductive fibers act on the sliding contact connection of the moving working surface, making the conductive fibers reliably connected to the working surface, thereby realizing the transmission of electrical signals such as voltage and current.

[0071] In some embodiments, regarding the fixing method between the fiber and the fixing block, the conductive fiber bundle 302 can be fixed to the conductive fixing block 301 by any of the following methods: physical pressing, bonding with conductive adhesive, tightening with conductive bolts, etc. It should be noted that the method of fixing the fiber should meet the fiber pull-out force design requirements; the specific design requirements can be determined according to the product and are not specifically limited here. In addition, the method of fixing the fiber should meet the conductivity design requirements of the conductive block; the specific design requirements can be determined according to the product and are not specifically limited here.

[0072] In some embodiments, the conductive support 10 is used to draw out electrical signals such as current and voltage. Therefore, the conductive support 10 is a type of conductor structure whose reliable conductivity meets design requirements. In practice, the conductive support 10 can be a support made of any of the following materials: aluminum, copper, or stainless steel.

[0073] In some embodiments, the fastener 20 is a type of fastening component used to secure the conductive brush module 30 to the conductive support 10, so the fastener 20 can be a conductive component or a non-conductive component.

[0074] In one example, the fastener 20 is selected as a conductive rivet or bolt, thereby using the same set of rivets or bolts to securely connect multiple conductive brush modules 30 to the conductive bracket 10. Furthermore, the conductivity of the fastener 20 reliably ensures the conductivity between the conductive brush modules 30 and the conductive bracket 10. In implementation, the fastener 20 includes rivets or bolts made of any of the following materials: aluminum, copper, or stainless steel.

[0075] It should be noted that the number of fasteners 20 can be determined according to the fastening requirements of the conductive brush module 30 to the conductive bracket 10, and no specific limit is made here.

[0076] In some embodiments, the conductive support 10 can be configured as a U-shaped component, a comb-shaped component, or other structural form that facilitates the flexible assembly of the conductive brush module 30. That is, when the conductive support 10 is configured as a U-shaped or comb-shaped structure, the conductive brush module 30 can be installed in the space of the U-shape or in the space between the teeth of the comb. Through these installation spaces, different numbers of conductive brush modules can be flexibly adapted, thereby flexibly forming conductive block products with different conductive contact surfaces.

[0077] In some implementations, different numbers of conductive brush modules can be adapted to assemble on the same conductive bracket by selecting different fasteners in the foregoing examples. In the following examples, different conductive block products can be assembled on the same conductive bracket using the same fasteners by adding adapter blocks.

[0078] In practice, the conductive block of this application also includes an adapter block (not shown in the schematic diagram). The adapter block is an assembly block without conductive fibers. The adapter block and the conductive brush module are fastened to the conductive bracket together through the fasteners. It should be noted that the adapter block and the conductive brush module are installed together in the conductive bracket. By adding or removing the adapter block (or the conductive brush module), the conductive block can flexibly provide contact surfaces of different sizes. The shape, size, and installation method of the adapter block can be the same as or different from the conductive brush module, and are not specifically limited here.

[0079] In some implementations, by adding corresponding clamping block structural components to the conductive support, these clamping blocks can be used as general-purpose components. In practical applications, these clamping blocks can be flexibly used to add several conductive brush modules to the same conductive support, thereby flexibly expanding the conductive contact surface of the conductive blocks.

[0080] In practice, the conductive block of this application also includes a fixing clamp (not shown in the schematic diagram), wherein the fixing clamp is used to clamp the conductive brush module 30, so as to add or remove the conductive brush module on the conductive support 10, so that the conductive block provides conductive contact surfaces with different preset requirements in size, shape and other aspects in the direction of the fiber conductive end.

[0081] For example, in Figure 1 In the illustrated conductive block, a fixing clamp can be added to the upper and / or lower end of the conductive support 10. Figure 1 (Not illustrated in the diagram), thereby adding more conductive brush modules 30 by fixing the clamping block, so that the conductive block can flexibly provide conductive contact surfaces of different sizes in the direction of conductive contact end.

[0082] For example, in Figure 1 In the conductive block shown in the diagram, a fixing clamp can be added inside the conductive support 10 (i.e., between the conductive brush modules 30). Figure 1 (Not illustrated in the diagram), thereby changing the position between the conductive brush modules 30 by fixing the clamping blocks, so that the conductive blocks can flexibly provide conductive contact surfaces of different sizes and shapes in the direction of conductive contact ends.

[0083] It should be noted that the fixing block can be a clamping block equipped with conductive fiber bundles, and the conductive fiber bundles can be the same as or different from the fiber bundles in the conductive brush module in any aspect such as spacing, length, or size; there is no specific limitation. Alternatively, the fixing block can also be a clamping block without conductive fiber bundles, which facilitates the installation of the fixing block between conductive brush modules to change the fiber bundle spacing of different conductive brush modules.

[0084] In some implementations, by recombining and assembling multiple conductive brush modules, conductive block products that can provide different conductive contact surfaces can be obtained. That is, by having multiple conductive fiber bundles jointly form a planar contact surface or an arc-shaped contact surface at the sliding contact end, the conductive block can easily adapt to conductive contact surfaces of different shapes.

[0085] refer to Figure 7 As illustrated, multiple conductive fiber bundles together form an arc-shaped contact surface at the sliding contact end, allowing the conductive block to adapt to the sliding contact requirements of the arc-shaped conductive contact surface. It should be noted that the arc surface can be an arc surface that meets the preset curvature requirements, and the arc surface can be an outwardly convex arc surface or an inwardly concave arc surface; no specific limitation is made here.

[0086] refer to Figure 8 As shown, multiple conductive fiber bundles together form a planar contact surface at the sliding contact end, thus enabling the conductive block to adapt to the sliding contact requirements of the planar conductive contact surface.

[0087] In some implementations, different combinations of the shape of the conductive fixing block, the position of the fixing hole on the conductive fixing block, and the length of the conductive fiber bundle can flexibly form a variety of conductive brush modules of different specifications, thereby forming the planar contact surface or the arc-shaped contact surface at the conductive contact end of the fiber by multiple conductive brush modules.

[0088] For example, among the selected multiple conductive brush modules, all the conductive fixing blocks have the same shape, all the conductive fixing blocks have the same fixing hole at the same position, and all the multiple conductive fiber bundles have the same length. Thus, through identical conductive brush modules, the multiple conductive fiber bundles together form a planar contact surface at the sliding contact end.

[0089] For example, among the selected multiple conductive brush modules, all the conductive fixing blocks are provided with the same shape, and all the conductive fixing blocks are provided with the fixing holes in the same position, and some or all of the multiple conductive fiber bundles are provided with different lengths, so that the multiple conductive fiber bundles together form an arc-shaped contact surface at the sliding contact end.

[0090] For example, among the selected multiple conductive brush modules, all the conductive fixing blocks are provided with the same shape, and some or all of the conductive fixing blocks are provided with fixing holes at different positions, and all the multiple conductive fiber bundles are provided with the same length, so that the multiple conductive fiber bundles together form an arc-shaped contact surface at the sliding contact end.

[0091] For example, among the selected multiple conductive brush modules, all the conductive fixing blocks are provided with the same shape, and some or all of the conductive fixing blocks are provided with fixing holes at different positions, and some or all of the multiple conductive fiber bundles are provided with the same length, so that the multiple conductive fiber bundles together form a planar contact surface or an arc-shaped contact surface at the sliding contact end.

[0092] For example, among the selected multiple conductive brush modules, some or all of the conductive fixing blocks are provided with different shapes, and all of the conductive fixing blocks are provided with fixing holes in the same position, and all of the multiple conductive fiber bundles are provided with the same length, so that the multiple conductive fiber bundles together form an arc-shaped contact surface at the sliding contact end.

[0093] For example, among the selected multiple conductive brush modules, some or all of the conductive fixing blocks are provided with different shapes, and all of the conductive fixing blocks are provided with fixing holes in the same position, and some or all of the multiple conductive fiber bundles are provided with different lengths, so that the multiple conductive fiber bundles together form a planar contact surface or an arc-shaped contact surface at the sliding contact end.

[0094] For example, among the selected multiple conductive brush modules, some or all of the conductive fixing blocks are provided with different shapes, and some or all of the conductive fixing blocks are provided with fixing holes in different positions, and all of the multiple conductive fiber bundles are provided with the same length, so that the multiple conductive fiber bundles together form a planar contact surface or an arc-shaped contact surface at the sliding contact end.

[0095] For example, among the selected multiple conductive brush modules, some or all of the conductive fixing blocks are provided with different shapes, and some or all of the conductive fixing blocks are provided with fixing holes at different positions, and all of the multiple conductive fiber bundles are provided with different lengths, so that the multiple conductive fiber bundles together form a planar contact surface or an arc-shaped contact surface at the sliding contact end.

[0096] It should be noted that selecting appropriate conductive brush modules to jointly form the required planar or arc-shaped conductive contact surface should fall within the protection scope of this application. The above examples are only for reference and illustration, so that those skilled in the art can form the conductive block contact surface required in actual applications based on the above examples.

[0097] In summary, the structure of multiple conductive brush modules 30 can be designed as a universal structure, which can be the same or different. It should be noted that the universal structure here refers to the same or different structures, which can refer to the length, size, and other structures of the electrical fiber bundles, or to the shape, size, and the position and structure of the fixing holes on the fixing block that fixes the conductive fibers.

[0098] For example, the conductive fibers 302 of each conductive brush module 30 can be set to be the same or different in length, and / or the conductive fixing blocks 301 of each conductive brush module 30 can be set to be the same or different in size, shape, etc., thereby forming a variety of conductive brush modules 30. Then, when facing the need for contact of conductive surfaces of different shapes, only the appropriate conductive brush module 30 needs to be selected for assembly, and the required conductive block product can be formed quickly and accurately.

[0099] In addition, the conductive fixing block 301 of the conductive brush module 30 is also provided with mounting holes 303. It should be noted that the mounting holes 303 in each conductive fixing block 301 can be set in the same or different corresponding positions. By setting the mounting holes 303 in the same or different positions, a variety of conductive brush modules 30 can be formed. Therefore, when facing the need for contact with conductive surfaces of different shapes, it is only necessary to select the conductive brush module 30 with the appropriate fixing block 303 for assembly, so that the required conductive block product can be formed quickly and accurately.

[0100] For example, regarding the aforementioned Figure 8 For the schematic planar conductive surface sliding contact electrical connection, multiple conductive brush modules 30 with the same structure can be selected to form the conductive block, or multiple conductive brush modules 30 with different structures can be selected. For example, the fiber lengths of the conductive brush modules 30 are different, but after being adapted by fixing holes, they can be installed on the conductive bracket so that the fiber contact tips of each conductive brush module 30 can form a plane to fit the planar conductive contact surface.

[0101] For example, by setting conductive brush modules 30 with the same structure (including fixing holes 303 in the same position), after multiple conductive brush modules are fastened to the conductive bracket by the same fasteners, the tips of the conductive fibers in the multiple conductive brush modules that are used to slide in contact with the conductive surface can jointly form a planar shape, thereby being able to fit the planar conductive surface.

[0102] For example, regarding the aforementioned Figure 7 The schematic diagram of the arc-shaped conductive surface sliding contact electrical connection requires the use of multiple conductive brush modules 30 with the same shape and fiber length but different mounting and fixing hole positions to form the conductive block. Alternatively, multiple conductive brush modules 30 with the same structure can be used, such as having the same fiber length and fixing holes. After different conductive brush modules are fastened and adapted by different fasteners, the fiber contact tips of each conductive brush module 30 form an arc surface to fit the arc-shaped conductive surface.

[0103] For example, by setting mounting holes at different positions, that is, in multiple conductive brush modules, the mounting holes set on some conductive brush modules 30 (see above) are used. Figure 6The position of the illustrative fixing hole 303 is different from the position of the fixing holes set in other conductive brush modules. Therefore, after multiple conductive brush modules are fastened to the conductive bracket by the same fastener based on the fixing holes, the tips of the conductive fibers in the multiple conductive brush modules that are used to slide in contact with the conductive surface can also form an arc shape with a preset curvature, thereby fitting the arc-shaped conductive surface.

[0104] In some implementations, to meet the different contact requirements of conductive surfaces, i.e., to ensure that the fiber contact tips of the conductive brush module form suitable flat or curved surfaces, after the conductive brush module 30 is installed on the conductive bracket 10, a preset gap, such as 0.1-3mm, is left between the conductive brush module 30 and the conductive bracket 10. Therefore, by reserving a design gap, without changing the structure of each component, it is possible to flexibly form the virtual surface (such as a flat surface, curved surface, etc.) formed by the fiber tips required for the conductive surface simply by selecting different conductive brush modules during assembly.

[0105] In some implementations, in addition to providing corresponding mounting holes on the conductive block, a corresponding mounting plate can also be added to the conductive block to accommodate different installation needs.

[0106] In one example, the conductive block of this application also includes a mounting bracket 40 (e.g., Figures 9 to 13 (As shown in the example), the conductive bracket 40 has a through hole or a threaded hole, and the conductive bracket 10 is fastened to the mounting bracket 40 through the through hole or threaded hole.

[0107] In some embodiments, the mounting bracket 40 is preferably designed as an L-shaped plate (e.g. Figure 13 (Illustrative example), thereby fastening one arm of the L-shaped plate to the conductive support 10.

[0108] In practice, the through hole or threaded hole is located on the top side of the conductive bracket 10 away from the conductive fiber, which facilitates the installation of the first mounting arm 402 of the L-shaped plate onto the top of the conductive bracket 10, and the installation of the second mounting arm 403 of the L-shaped plate onto the reserved structural part of the conductive ring. The L-shaped mounting bracket 40 makes it very convenient for the conductive block to meet the installation requirements of the conductive ring for the conductive block.

[0109] In some embodiments, the mounting bracket 40 is provided with a plurality of oblong mounting holes 401 for mounting and fixing. By configuring the oblong hole structure to enable fine-tuning during installation, it is convenient to make actual fine adjustments according to installation needs.

[0110] Based on the same inventive concept, embodiments of this specification also provide technical solutions such as conductive rings and motors using the conductive block.

[0111] This application provides a conductive ring, including: a conductive ring support and a plurality of conductive blocks, wherein the plurality of conductive blocks are distributed on the conductive ring support.

[0112] Referring to the above Figure 7 As shown, a conductive ring (not shown in the figure) with a conductive block installed can achieve a sliding contact electrical connection with an arc-shaped conductive surface.

[0113] Referring to the above Figure 8 As shown, a conductive ring (not shown in the figure) with a conductive block installed can achieve a sliding contact electrical connection with a planar conductive surface.

[0114] It should be noted that the conductive surface can be the conductive shaft inside the motor that requires sliding contact electrical connection. The conductive contact surface of this conductive shaft can be a plane or an arc surface; no specific limitation is made here. Additionally, the conductive ring support can be a circular ring or other structural shapes; no specific details are provided here.

[0115] This application provides a motor, which may include: a conductive shaft and a conductive ring, wherein the conductive ring is in sliding contact with the conductive shaft; or, a conductive shaft and a conductive block, wherein the conductive block is in sliding contact with the conductive shaft. It should be noted that the conductive ring and conductive block are any of the examples provided in the above examples of this application, and will not be elaborated further here; and the conductive shaft may be a conductive component that achieves sliding contact electrical connection through a plane, an arc surface, etc., and will not be specifically described here.

In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
