Detailed implementation manners

[0019] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0020] The following describes the implementation modes of the present application through specific examples. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments.

It should be noted that, without conflict, the following embodiments and the features in the 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 creative efforts belong to the scope protected by the present application.

[0021] It should be noted that the following describes various aspects of the embodiments within the scope of the appended claims. 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 illustrative only. Based on the present application, those skilled in the art should understand that one 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 aspects described herein can be used to implement the device and / or practice the method. Additionally, this device and / or method can be implemented using other structures and / or functions in addition to one or more of the aspects described herein.

[0022] It should also be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present application schematically. The drawings only show the components related to the present application, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0023] In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the examples can be practiced without these specific details.

[0024] The conductive block in the slip ring realizes electrical connection through the sliding friction contact between the conductive fiber and the conductive surface. Therefore, the conductive block is a key component similar to a brush. In the sliding friction contact, the conductive fiber may be slowly worn, and then redundant substances are accumulated on the conductive surface, ultimately deteriorating the working environment of the conductive fiber. Also, other redundant substances may be brought into the actual working scenario, such as adding lubricating materials (such as lubricating oil) for lubrication, or dust, debris, etc. These redundant substances will also deteriorate the working environment of the conductive fiber.

[0025] Therefore, in order to provide a better working environment for the conductive fibers, a new conductive block structure is proposed: Refer to Figure 1 Schematic diagram of the electrical contact of the planar conductive surface and Figure 2 the electrical contact of the arc-shaped conductive surface) connection. An oil scraping block 3 is added to the end of the conductive block 1. For example, in the sliding direction, the oil scraping 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 scraping block 3 can scrape off the excess substances on the conductive surface, thereby providing a cleaner working environment for the conductive brush 4 (or rather, the conductive fiber bundle 5).

[0026] The following combines the drawings to illustrate the technical solutions provided by the embodiments of the present application.

[0027] Refer to Figures 3 to 6 Schematic diagram. In the embodiments of this specification, a conductive block is provided. The conductive block includes: a conductive bracket 10, a fastener 20, at least one oil scraping module 30, and a plurality of conductive brush modules 40. In practice, the oil scraping module 30 is at least arranged at one end of the conductive bracket 10. Thus, in the sliding contact between the conductive brush module 40 and the conductive surface (which can refer to the aforementioned Figure 1 Schematic diagram), the oil scraping module 30 approaches or contacts the conductive surface, and then can scrape off the excess substances existing on the conductive contact surface along the sliding direction, providing a better working environment for the conductive brush module 40, reducing the sliding friction between the conductive brush module 40 and the conductive surface, enhancing the electrical conductivity, etc. In addition, the fastener 20 is used to fixedly connect the oil scraping module 30, the conductive brush module 40 and the conductive bracket 10.

[0028] In some embodiments, the structure of the plurality of conductive brush modules 40 usually includes conductive fibers and a conductive fixing structure for fixing the fibers. Moreover, usually a plurality of conductive brush modules 40 are configured in one conductive block 1, and the common conductive surface is usually planar or arc-shaped. Therefore, the conductive brush module 40 can be designed as a general structure, and the general structure can adopt the same structure or different structures. It should be noted that the general structure being the same or different can refer to the length structure of the conductive fibers, or the outer shape structure of the fixing block for fixing the conductive fibers, the position structure of the mounting holes of the fixing block, etc.

[0029] Refer to Figure 7 Schematic diagram. Each conductive brush module 40 can include a conductive fixing block 401 and conductive fibers 402. One end of the conductive fibers 402 is conductively fixed in the conductive fixing block 401. At this time, the other end of the conductive fibers 402 serves as a sliding contact end for contacting the conductive surface to achieve sliding contact electrical connection.

[0030] In implementation, 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 blocks 401 of each conductive brush module 40 can be set to be the same or different in size, shape, etc., so as to form a variety of conductive brush modules 40. Then, when facing the need for conductive surface contact of different shapes, only by selecting a suitable conductive brush module 40 for assembly can the required conductive block product be quickly and accurately formed.

[0031] In addition, fixing holes 403 for installation are also provided on the conductive fixing blocks 401 of the conductive brush module 40. It should be noted that in each conductive fixing block 401, the fixing holes 403 can be set at the same or different corresponding positions. Thus, by setting the fixing holes 403 at the same or different positions, a variety of conductive brush modules 40 are formed. Then, when facing the need for conductive surface contact of different shapes, only by selecting a conductive brush module 40 with a suitable fixing hole 403 for assembly can the required conductive block product be quickly and accurately formed.

[0032] For example, for the electrical connection requirement of the sliding contact of the planar conductive surface shown above Figure 1 , multiple conductive brush modules 40 with the same structure can be selected to form the conductive block (specifically, refer to the structure diagrams shown above Figure 1 , Figure 3 etc.). Or multiple conductive brush modules 40 with different structures (not shown in the figure) can also be selected. For example, although the fiber lengths in the conductive brush modules are different, after being adapted by the fixing blocks and finally installed on the conductive bracket, the contact tips of the fibers of each conductive brush module 40 can still form a plane to fit the planar conductive surface.

[0033] Combined with the above Figures 2 to 6 etc. diagrams, by setting conductive brush modules 40 with the same structure (including fixing holes 403 at the same positions), after multiple conductive brush modules are fastened to the conductive bracket by the same fasteners (refer to the structures shown above Figure 1 , Figures 3 to 6 etc.), the contact tips of the conductive fibers used for sliding contact with the conductive surface in multiple conductive brush modules can jointly form a planar shape, so as to fit the planar conductive surface.

[0034] For example, for the electrical connection requirement of the sliding contact of the arc-shaped conductive surface shown above Figure 2 , multiple conductive brush modules 40 with the same outer shape, the same fiber length but different positions of the installation fixing holes can be selected to form the conductive block (specifically, refer to the above Figure 2(structural schematic), or multiple conductive brush modules 40 with the same structure (not shown in the figure) can also be selected. For example, the fiber length, fixing block, etc. in the conductive brush module are all the same. After fastening and adapting different conductive brush modules with fasteners, the fiber contact tips of each conductive brush module 40 form an arc surface to fit the arc-shaped conductive surface.

[0035] Combined with the foregoing Figure 2 、 Figure 7 and other illustrations, by setting installation and fixing holes at different positions, that is, in multiple conductive brush modules, the positions of the first fixing holes (see the fixing hole 403 shown in the foregoing Figure 7 illustration) provided on some conductive brush modules 40 are different from the positions of the first fixing holes provided on other conductive brush modules. Thus, after multiple conductive brush modules are fastened to the conductive bracket by the same fasteners based on the first fixing holes (refer to the structure shown in the foregoing Figure 2 ), the tops of the conductive fibers used for sliding contact with the conductive surface in multiple conductive brush modules can also jointly form an arc surface shape with a preset radian, so as to be able to fit the arc-shaped conductive surface.

[0036] In some embodiments, the conductive fiber 402 can be a reliable flexible conductive fiber, such as a carbon fiber with a conductive coating, a composite or monomeric metal fiber, a high-molecular wear-resistant composite fiber, carbon cloth, etc. Thus, through the action of the conductive fiber on the moving working surface of the sliding contact connection, the conductive fiber is reliably connected to the working surface, thereby realizing the transmission of electrical signals such as voltage and current.

[0037] In some embodiments, for the fixing method between the fiber and the fixing block, the conductive fiber can be fixed in the conductive fixing block by any of the following methods: physical crimping, conductive glue bonding, conductive bolt fastening, etc. It should be noted that the method of fixing the fiber should meet the design requirements of the fiber pull-off force, and the specific design requirements can be determined according to the product, and no specific limitation is made here. In addition, the method of fixing the fiber should meet the conductive design requirements of the conductive block, and the specific design requirements can be determined according to the product, and no specific limitation is made here.

[0038] In some embodiments, the conductive bracket is used to lead out electrical signals such as current and voltage, so the conductive bracket is a type of conductor structure with reliable conductivity that meets the design requirements. In implementation, the conductive bracket can be a bracket made of any of the following materials: aluminum, copper, stainless steel.

[0039] 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.

[0040] In one example, the fastener is selected as a conductive rivet or bolt, so that a plurality of conductive brush modules are fastened to the conductive bracket by using the same set of rivets or bolts, and the conductivity between the conductive brush module and the conductive bracket is reliably ensured by using the conductivity of the fastener. In implementation, the fastener 20 includes a rivet or bolt made of any of the following materials: aluminum, copper, stainless steel;

[0041] In some embodiments, the oil scraping module 30 can be a type of wear-resistant block structure component. The width of the oil scraping 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 scraping module 30 is the same as that of the conductive brush module 40, or slightly larger or slightly smaller than the width of the conductive brush module 40, etc., so as to flexibly meet the width design requirements of the conductive block in different scenarios. In implementation, the oil scraping module 30 can include a block module made of any of the following wear-resistant materials: PTFE, PU, carbon block.

[0042] In implementation, the oil scraping module 30 can be set as a wedge-shaped structure (specifically, reference can be made to the foregoing Figures 1 to 5 and other structure diagrams), which not only meets the overall strength requirements of the structural component, 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.

[0043] In some embodiments, for the installation requirements of the conductive brush module, the conductive bracket can be set as a frame-type bracket or a comb-tooth type bracket.

[0044] Refer to Figures 3 to 6 the diagram, the conductive bracket 10 is provided with a comb-tooth-shaped structure portion 101. The conductive brush module 40 can be arranged between the teeth 102 of the comb-tooth-shaped structure portion 101, and the oil scraping module 30 can be arranged between the teeth of the comb-tooth-shaped structure portion 101 (see the foregoing Figure 3 diagram) or outside the teeth 102 (that is, outside the end of the bracket, reference can be made to the following Figure 9 diagram). In implementation, the fastener 20 can be selected as a long strip-shaped rivet or bolt, so as to penetrate through the oil scraping module, the conductive brush module and the comb teeth and fasten and connect them.

[0045] In some embodiments, for the conductive connection requirements, the conductive bracket can be further improved. For example, a connection hole 103 is opened on the tooth 102 of the comb-tooth-shaped structure portion 101. The connection hole 103 can be a through hole or a threaded hole, etc., which is convenient for conductive connection. Similarly, an installation hole 104 is opened on the conductive bracket 10 (or the comb-tooth-shaped structure portion 101), and the installation hole 104 can be a through hole or a threaded hole. In some examples, the installation hole 104 can be set as a hole structure that can realize fine-tuning installation (such as a waist-shaped hole), which is convenient for fine-tuning according to the installation requirements.

[0046] In some embodiments, an interference fit structure is adopted between the conductive brush module 40 and the side surface of the comb teeth 102 of the comb-shaped structure portion 101, which is not only beneficial for firm installation but also can ensure conductivity.

[0047] In some embodiments, for different conductive surface contact requirements, that is, to form a suitable surface at the fiber contact top of the conductive brush module (such as the Figure 1 schematic plane, Figure 2 schematic arc surface, etc.), referring to the foregoing Figures 1 to 7 schematic, after the conductive brush module 40 is installed between the comb teeth 102 of the comb-shaped structure portion 101, a gap with a preset distance is left between the root of the comb teeth 102 of the comb-shaped structure portion 101 and the conductive brush module 40, such as a gap of 0.5 - 2 mm. Therefore, by reserving a design gap, without changing the structure of each component, only by selecting different conductive brush modules during assembly, a virtual surface (such as a plane, arc surface, etc.) formed by the fiber tops required for the conductive surface can be flexibly formed.

[0048] In some embodiments, referring to the Figure 11 schematic, after the conductive brush module 40 is installed between the comb teeth 102 of the comb-shaped structure portion 101, the comb teeth 102 of the comb-shaped structure portion 101 can be higher than the conductive brush module. It should be noted that the comb teeth 102 of the comb-shaped structure portion 101 can be flush with the conductive brush module (referring to the Figure 6 schematic structure), or the comb teeth 102 of the comb-shaped structure portion 101 can be lower than the conductive brush module (not shown in the schematic).

[0049] In some embodiments, other optimization and improvement measures can also be taken for the comb structure. For example, the same spacing is set between the comb teeth 102 of the comb-shaped structure portion 101, that is, the comb teeth are designed with equal spacing, and a conductive brush module 40 with the same thickness can be used to achieve a general design; for example, each comb tooth 102 of the comb-shaped structure portion 101 is set to the same shape and size.

[0050] In some embodiments, the present application also provides another conductive block structure, which can more flexibly meet the requirements for the shape of the conductive block in different scenarios.

[0051] Referring to the Figures 9 to 13 schematic, the conductive block further includes a fixed clamping block 50. By arranging the fixed clamping block 50 at the end of the conductive bracket 10, it is very convenient to clamp the oil scraping module according to the scenario requirements, that is, to clamp the oil scraping module 30 at the end of the conductive bracket 10 through the fixed clamping block 50. For example, in some occasions, only one oil scraping module 30 is needed, then the oil scraping module 30 can be fixed at one end of the conductive bracket 10 through the fixed clamping block 50, and the installation of the oil scraping module 30 and the fixed clamping block 50 is omitted at the other end of the conductive bracket 10, further reducing the volume of the conduction block and also well meeting the scenario requirements.

[0052] In some embodiments, with reference to Figures 13 to 15 as shown, the conductive bracket 10 is provided with a flat surface and a first inclined surface at the end for clamping the oil scraping module. The fixed clamping block 50 is provided with a corresponding clamping surface and a second inclined surface. The clamping surface of the fixed clamping block 50 and the flat surface of the conductive bracket 10 jointly clamp and fix the conductive brush module 40. The first inclined surface and the second inclined surface cooperate to form an inclined surface, making the conductive block more compact. In practice, the fixed clamping block 50 is fastened to the conductive bracket 10 by screws 60.

[0053] In practice, the first inclined surface is arranged at the top of the end of the conductive bracket 10. Through the inclined surface design, the occupied space volume at the top of the end of the conductive bracket 10 is reduced. Correspondingly, the second inclined surface is arranged at the top of the fixed clamping block 50, also with an inclined surface design to reduce the space volume of the fixed clamping block 50 in the top direction. Then, after the first inclined surface and the second inclined surface cooperate, a new inclined surface is formed, so that the conductive block with the new inclined surface can save more space volume in the top direction, facilitating the flexible installation and use of the conductive block in applications requiring a small volume.

[0054] It should be noted that by improving the design of the conductive bracket 10 and adding the fixed clamping block 50, the usage requirements of the conductive brush module 40 in the scenario can be flexibly adapted, and the conductive block structure can also have the advantages of miniaturization and generalization.

[0055] In addition, for the conductive blocks in other structural forms in this application, such as the Figures 1 to 8 conductive block shown as above, the inclined surface can also be designed similar to the above embodiment, that is, the top of the main structure of the conductive bracket 10 is set as an inclined surface, that is, a piece is cut off from the top of the end of the main structure of the conductive bracket 10, so that the end of the main structure of the conductive bracket 10 has an inclined surface-shaped top, so that the conductive block with an inclined surface-shaped top can more flexibly adapt to different usage and installation requirements.

[0057] In some embodiments, the present application provides a conductive ring, including: a conductive ring bracket and a plurality of conductive blocks, wherein the plurality of conductive blocks are distributed on the conductive ring bracket.

[0060] It should be noted that the conductive surface can be the conductive shaft that requires sliding contact electrical connection in the motor. The conductive contact surface of the conductive shaft can be a plane or an arc surface, and no specific limitation is made here. In addition, the conductive ring bracket can be a circular ring or other structural shapes, and no specific description is made here.
