[0047] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0048] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, in the absence of conflict, the features in the following embodiments and embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of this application.

[0049] It should be noted that various aspects of the embodiments within the scope of the appended claims are described below. It should be apparent that the aspects described herein can be embodied in a wide variety of forms, and any specific structure and / or function described herein is merely illustrative. Based on this application, it should be understood by those skilled in the art that an aspect described herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number and aspect described herein can be used to implement an apparatus and / or practice a method. In addition, other structures and / or functionalities other than one or more of the aspects described herein can be used to implement this apparatus and / or practice this method.

[0050] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0051] Additionally, in the following description, specific details are provided to provide a thorough understanding of the examples, however, one skilled in the art will appreciate that the examples can be practiced without these specific details.

[0052] The conductive block in the conductive ring is electrically connected through sliding friction between the conductive fiber and the conductive surface, so the conductive block is a key component similar to a brush. During sliding friction contact, the conductive fiber may slowly wear out, and then accumulate as excess material on the conductive surface, eventually deteriorating the working environment of the conductive fiber. In addition, other excess materials may also be introduced into the actual working scene, such as lubricating materials (such as lubricating oil) for lubrication, and dust, debris, etc. These excess materials will also deteriorate the working environment of the conductive fiber.

[0053] Therefore, in order to provide a better working environment for the conductive fiber, a new conductive block structure is proposed: Figure 1 Planar conductive surface electrical contact and Figure 2 As shown in the figure, an oil scraper block 3 is added to the end of the conductive block 1, for example, in the sliding direction, the oil scraper block 3 is added to both ends or at least one end of the conductive block. Therefore, in the sliding contact between the conductive fiber bundle 5 of the conductive brush 4 and the conductive surface, the oil scraper block 3 can scrape off the excess material on the conductive surface, thereby providing a cleaner working environment for the conductive brush 4 (or the conductive fiber bundle 5).

[0054] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0055] refer to Figures 3 to 6 In the embodiment of the present invention, a conductive block is provided, which includes: a conductive bracket 10, a fastener 20, at least one oil scraping module 30 and a plurality of conductive brush modules 40. In the implementation, the oil scraping module 30 is at least provided at one end of the conductive bracket 10, so that the conductive brush module 40 and the conductive surface (refer to the aforementioned Figure 1 During sliding contact between the conductive surface (schematically shown), the oil scraper module 30 approaches or contacts the conductive surface, thereby scraping away excess material on the conductive contact surface along the sliding direction, providing a better working environment for the conductive brush module 40, reducing sliding friction between the conductive brush module 40 and the conductive surface, and enhancing conductive performance. Furthermore, the fastener 20 is used to securely connect the oil scraper module 30, the conductive brush module 40, and the conductive bracket 10.

[0056] In some embodiments, the structure of multiple conductive brush modules 40 can generally include conductive fibers and a conductive fixing structure for fixing the fibers. In addition, a conductive block 1 is generally configured with multiple conductive brush modules 40, and the common conductive surface is generally flat or curved. Therefore, the conductive brush modules 40 can be designed to have a universal structure, and the universal structure can adopt the same structure or different structures. It should be noted that the universal structure here can refer to the length structure of the conductive fibers, the external structure of the fixing block itself that fixes the conductive fibers, the position structure of the fixing hole of the fixing block, etc.

[0057] refer to Figure 7 As shown in FIG. 4 , each conductive brush module 40 may include a conductive fixing block 401 and a conductive fiber 402 , wherein one end of the conductive fiber 402 is conductively fixed in the conductive fixing block 401 , and the other end of the conductive fiber 402 serves as a sliding contact end for contacting the conductive surface to realize sliding contact electrical connection.

[0058] In practice, the conductive fibers 402 of each conductive brush module 40 can be set to be the same or different in length, and / or the conductive fixing block 401 of each conductive brush module 40 can be set to be the same or different in size, shape, etc., thereby forming a variety of conductive brush modules 40. When faced with the need to contact conductive surfaces of different shapes, it is only necessary to select the appropriate conductive brush module 40 for assembly to quickly and accurately form the required conductive block product.

[0059] In addition, the conductive fixing block 401 of the conductive brush module 40 is provided with fixing holes 403 for installation. It should be noted that the fixing holes 403 can be located at the same or different corresponding positions in each conductive fixing block 401. Thus, by providing fixing holes 403 at the same or different positions, a variety of conductive brush modules 40 can be formed. When contacting conductive surfaces of different shapes is required, the conductive brush module 40 with the appropriate fixing holes 403 can be selected for assembly to quickly and accurately form the desired conductive block product.

[0060] For example, for the aforementioned Figure 1 The electrical connection of the planar conductive surface sliding contact needs to be shown, and multiple conductive brush modules 40 of the same structure can be selected to form the conductive block (for details, please refer to the aforementioned Figure 1 、 Figure 3 etc.), multiple conductive brush modules 40 with different structures can also be selected (not shown in the figure). For example, the fibers in the conductive brush modules are of different lengths, but after being adapted by the fixing block and finally installed on the conductive bracket, the fibers of each conductive brush module 40 can also contact the top to form a plane to fit the planar conductive surface.

[0061] Combined with the above Figures 2 to 6By setting the conductive brush modules 40 with the same structure (including the fixing holes 403 at the same position), after the plurality of conductive brush modules are fastened to the conductive bracket by the same fastener (refer to the aforementioned Figure 1 、 Figures 3 to 6 etc.), the conductive fiber tips in the plurality of conductive brush modules for sliding contact with the conductive surface can together form a planar shape, thereby being able to fit the planar conductive surface.

[0062] For example, for the aforementioned Figure 2 The electrical connection needs of the arc-shaped conductive surface sliding contact shown in the figure can be formed by selecting multiple conductive brush modules 40 with the same shape and fiber length but different mounting hole positions to form the conductive block (for details, please refer to the aforementioned Figure 2 ), multiple conductive brush modules 40 with the same structure (not shown in the figure) can also be selected. For example, the fiber length, fixing blocks, etc. in the conductive brush modules are the same. After fastening and adapting the different conductive brush modules with fasteners, the fiber contact tops of each conductive brush module 40 form an arc surface to fit the arc-shaped conductive surface.

[0063] Combined with the above Figure 2 、 Figure 7 As shown in FIG. 1 , by setting the mounting fixing holes at different positions, that is, in a plurality of conductive brush modules, the first fixing holes (see the aforementioned Figure 7 The position of the fixing hole 403 shown in the figure is different from the position of the first fixing hole provided in other conductive brush modules, so that after the plurality of conductive brush modules are fastened to the conductive bracket by the same fastener based on the first fixing hole (refer to the aforementioned Figure 2 The structure shown in FIG3 shows a structure in which the conductive fiber tips in the plurality of conductive brush modules for sliding contact with the conductive surface can also jointly form an arc shape with a preset curvature, thereby being able to fit the arc-shaped conductive surface.

[0064] In some embodiments, the conductive fiber 402 can be a reliable flexible conductive fiber, such as carbon fiber with a conductive coating, composite or monomeric metal fiber, polymer wear-resistant composite fiber, carbon cloth, etc., so that the conductive fiber acts on the moving working surface of the sliding contact connection, so that the conductive fiber is reliably connected to the working surface, thereby realizing the transmission of electrical signals such as voltage and current.

[0065] In some embodiments, the conductive fibers can be secured to the conductive fixing block using any of the following methods: physical crimping, bonding with conductive glue, or tightening with conductive bolts. It should be noted that the fiber securing method must meet the fiber pull-out strength design requirements. The specific design requirements can be determined based on the product and are not specifically defined here. Furthermore, the fiber securing method must meet the conductivity design requirements of the conductive block. The specific design requirements can be determined based on the product and are not specifically defined here.

[0066] In some embodiments, the conductive bracket is used to extract electrical signals such as current and voltage, so the conductive bracket is a type of conductor structure with reliable conductivity that meets design requirements. In practice, the conductive bracket can be made of any of the following materials: aluminum, copper, or stainless steel.

[0067] In some embodiments, the fastener is a component used to fasten the conductive brush module to the conductive bracket, so the fastener can be a conductive component or a non-conductive component.

[0068] In one example, the fasteners are conductive rivets or bolts, so that multiple conductive brush modules can be fastened to the conductive bracket using the same set of rivets or bolts. Furthermore, the conductivity of the fasteners is used to reliably ensure the electrical conductivity between the conductive brush modules and the conductive bracket. In practice, the fasteners 20 include rivets or bolts made of any of the following materials: aluminum, copper, or stainless steel.

[0069] In some embodiments, the oil scraper module 30 can be a wear-resistant block-shaped structural component. The width of the oil scraper module 30 can be the same as or different from the width of the conductive brush module 40. For example, the width of the oil scraper module 30 can be the same as the width of the conductive brush module 40, or slightly larger or smaller than the width of the conductive brush module 40, thereby flexibly meeting the width design requirements of the conductive block in different scenarios. In practice, the oil scraper module 30 can include a block-shaped module made of any of the following wear-resistant materials: PTFE, PU, ​​or carbon block.

[0070] In practice, the oil scraping module 30 can be configured as a wedge-shaped structure (for details, please refer to the aforementioned Figures 1 to 5 The structure diagram (e.g., FIG) not only meets the overall strength requirements of the structural parts, but also provides a certain degree of flexibility for the oil scraping end, and reduces the thickness, etc., so that the oil scraping module has better scene adaptability.

[0071] In some embodiments, to meet the installation requirements of the conductive brush module, the conductive bracket can be configured as a frame-type bracket or a comb-teeth-type bracket.

[0072] refer to Figures 3 to 6As shown, the conductive bracket 10 is provided with a comb-shaped structure portion 101, the conductive brush module 40 can be provided between the comb teeth 102 of the comb-shaped structure portion 101, and the oil scraping module 30 can be provided between the comb teeth of the comb-shaped structure portion 101 (see the aforementioned Figure 3 Schematic diagram) or the outer side of the comb teeth 102 (ie, the outer side of the end of the bracket, see later Figure 9 In practice, the fastener 20 may be a long strip of rivets or bolts, which penetrate the oil scraping module, the conductive brush module, and the comb teeth and then fasten them together.

[0073] In some embodiments, the conductive bracket can be further improved to meet the needs of conductive connection. For example, the comb teeth 102 of the comb-tooth structure 101 are provided with connection holes 103, which can be through holes or threaded holes, to facilitate conductive connection. Similarly, the conductive bracket 10 (or the comb-tooth structure 101) is provided with mounting holes 104, which can be through holes or threaded holes. In some examples, mounting holes 104 can be configured to enable fine-tuning of the installation (such as waist holes), facilitating fine-tuning according to installation needs.

[0074] In some embodiments, an interference fit structure is adopted between the conductive brush module 40 and the side surfaces of the comb teeth 102 of the comb-tooth-shaped structure portion 101, which is not only conducive to fastening and installation, but also can ensure conductivity.

[0075] In some embodiments, in order to meet the different conductive surface contact requirements, the fiber contact top of the conductive brush module is formed into a suitable surface (such as the aforementioned Figure 1 Schematic plane, Figure 2 Schematic arc surface, etc.), refer to the aforementioned Figures 1 to 7 As shown in the figure, after the conductive brush module 40 is installed between the teeth 102 of the comb-tooth structure 101, a preset gap of, for example, 0.5-2mm is left between the base of the teeth 102 of the comb-tooth structure 101 and the conductive brush module 40. Therefore, by reserving this gap, the virtual surface (e.g., flat surface, curved surface, etc.) formed by the fiber tips required for the conductive surface can be flexibly formed by simply selecting different conductive brush modules during assembly without changing the structure of the individual components.

[0076] In some embodiments, reference Figure 11 As shown, after the conductive brush module 40 is installed between the comb teeth 102 of the comb-tooth structure portion 101, the comb teeth 102 of the comb-tooth structure portion 101 can be higher than the conductive brush module. It should be noted that the comb teeth 102 of the comb-tooth structure portion 101 can be flush with the conductive brush module (refer to the aforementioned Figure 6 ), or the comb teeth 102 of the comb-tooth structure portion 101 may be lower than the conductive brush module (not shown in the figure).

[0077] In some embodiments, other optimization and improvement measures can be made to the comb-tooth structure. For example, the comb teeth 102 of the comb-tooth structure portion 101 are arranged with the same spacing, that is, the comb teeth are designed with equal spacing, and the conductive brush modules 40 with the same thickness can be used to achieve a universal design; for example, the comb teeth 102 of the comb-tooth structure portion 101 are arranged with the same shape and size.

[0078] In some embodiments, the present application also provides another conductive block structure that more flexibly meets the requirements for the appearance of the conductive block in different scenarios.

[0079] refer to Figures 9 to 13 As shown in the figure, the conductive block also includes a fixing clamp 50. By arranging the fixing clamp 50 at the end of the conductive bracket 10, it is very convenient to clamp the oil scraper module according to the needs of the scene. That is, the fixing clamp 50 clamps the oil scraper module 30 at the end of the conductive bracket 10. For example, in some applications, only one oil scraper module 30 is needed. In this case, the oil scraper module 30 can be fixed to one end of the conductive bracket 10 using the fixing clamp 50, while the oil scraper module 30 and the fixing clamp 50 are omitted at the other end of the conductive bracket 10. This further reduces the volume of the conductive block and also meets the needs of the scene.

[0080] In some embodiments, reference Figures 13 to 15 As shown, the conductive bracket 10 has a flat surface and a first inclined surface at the end that holds the oil scraper module. The fixed clamp 50 has a corresponding clamping surface and a second inclined surface. The clamping surface of the fixed clamp 50 and the flat surface of the conductive bracket 10 together clamp and secure the conductive brush module 40. The first and second inclined surfaces cooperate to form an inclined surface, making the conductive block more compact. In practice, the fixed clamp 50 is fastened to the conductive bracket 10 by screws 60.

[0081] During implementation, the first slope is set at the top of the end of the conductive bracket 10, and the slope design is used to reduce the space volume occupied by the top of the end of the conductive bracket 10. Correspondingly, the second slope is set at the top of the fixed clamp block 50, and the slope design is also used to reduce the space volume of the fixed clamp block 50 in the top direction. Then, the first slope and the second slope are matched and spliced ​​to form a new slope, so that the conductive block with the new slope can save more space volume in the top direction, which facilitates the flexible installation and use of the conductive block in situations where a small volume is required.

[0082] It should be noted that by improving the design of the conductive bracket 10 and adding the fixing clamp 50, the use requirements of the conductive brush module 40 in the scene can be flexibly adapted, and the conductive block structure can also have the advantages of miniaturization and universality.

[0083] In addition, the conductive blocks of other structural forms in this application, such as the aforementioned Figures 1 to 8The conductive block shown in the figure can also be designed with a slope similar to the above-mentioned embodiment, that is, the top of the main structure of the conductive bracket 10 is set as a slope, that is, a piece of the top on the end of the main structure of the conductive bracket 10 is cut off, so that the end of the main structure of the conductive bracket 10 has a sloped top, so that the conductive block with a sloped top at the end can be more flexibly adapted to different usage and installation requirements.

[0085] In some embodiments, the present application provides a conductive ring, comprising: a conductive ring support and a plurality of conductive blocks, wherein the plurality of conductive blocks are distributed on the conductive ring support.

For the specific schematic diagram of the contact electrical connection of the arc-shaped conductive surface, please refer to the aforementioned Figure 2 The above is a hint and will not be expanded here.

[0088] It should be noted that the conductive surface can be a conductive shaft within the motor that requires sliding contact and electrical connection. The conductive contact surface of the conductive shaft can be a flat surface or an arc surface, which is not specifically limited here. In addition, the conductive ring bracket can be a circular ring or other structural shapes, which are not specifically described here.

It should be noted that the conductive ring and the conductive block are any of the examples provided above in this application and will not be further elaborated here; and the conductive shaft may be a conductive component that achieves sliding contact and electrical connection via a flat surface, an arc surface, or the like, and will not be described in detail here.
