Description

Technical Field

[0001] This utility model relates to the field of slip ring technology, specifically to a wireless slip ring device for wireless communication and wireless power supply. Background Technology

[0002] In the operation of precision equipment such as robot joints, gimbals, surveillance cameras, and die bonders, stable power supply and high-speed data transmission between rotating components are core requirements. While current mainstream contact slip ring solutions are widely used, they suffer from the following significant drawbacks: 1. Lifespan bottleneck: It relies on the physical contact between the gold-plated metal brush and the metal ring to transmit electrical energy and data signals. Long-term rotational friction will cause the plating to wear down gradually, deteriorate the contact performance, and affect the reliability of transmission. 2. Unstable impedance: The contact resistance changes dynamically with wear, making it difficult to maintain a constant impedance, which restricts the realization of high-speed signal transmission; 3. Structural and cost disadvantages: It is bulky and complex in structure, and the manufacturing cost is high due to precision components (such as precious metal plating).

[0003] The aforementioned pain points of existing contact slip ring devices have driven the industry's demand for the application of non-contact transmission technology in slip ring devices. Utility Model Content

Detailed Implementation

[0018] To explain in detail the technical principles, implementable specific solutions, possible application scenarios, and achievable objectives and effects of this utility model, exemplary embodiments of this utility model will be described in more detail below with reference to the accompanying drawings. It should be understood that the embodiments described herein and the embodiments shown in the accompanying drawings are only used to more clearly illustrate the technical solutions of this utility model, and are therefore only examples intended to explain this utility model, and should not be construed as limiting this utility model. It should be understood that this utility model can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0019] This invention places the wireless duplex communication component on the end face of the slip ring assembly and adopts a multi-ring arrangement design.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] Please see Figure 1 , Figure 2a -b and Figure 3 . Figure 1 An exemplary structural diagram of a wireless slip ring device for wireless communication and wireless power supply provided for an embodiment of this utility model; Figure 2a -b are schematic diagrams of the first and second layout designs of the wireless communication component in specific embodiments of this utility model, respectively. Figure 2a In -b, T is used to simplify the transmitting module TX, and R is used to simplify the receiving module RX; Figure 3 This is an exemplary layout design diagram of the wireless power supply component and the wireless communication component in an embodiment of this utility model.

[0022] This utility model provides a wireless slip ring device for wireless communication and wireless power supply, which is in simplex mode. For example... Figure 1 As shown, it includes a rotating slip ring assembly 1, a fixed slip ring assembly 2, a wireless communication assembly 3, and a wireless power supply assembly 4; the wireless communication assembly includes at least one transmitting module TX and at least one receiving module RX; the wireless power supply assembly 4 includes a transmitting coil 41 and a receiving coil 42; the fixed slip ring assembly 2 and the rotating slip ring assembly 1 are arranged end to end along the rotation axis, and the corresponding end faces of the two are spaced apart by a preset distance.

[0023] The fixed slip ring assembly 2 and the rotating slip ring assembly 1 are coaxially aligned and corresponding. During operation, the rotating slip ring assembly 1 rotates along its common axis, while the corresponding fixed slip ring assembly 2 remains stationary. For ease of description and understanding, the corresponding end faces of the end-to-end fixed and rotating slip ring assemblies are referred to as "corresponding end faces." It is understood that there is a preset distance between the corresponding end faces of the fixed slip ring assembly and the rotating slip ring assembly. Preferably, to ensure the stability of wireless communication / energy transmission between the two slip ring assemblies, the distance between the corresponding end faces of the fixed slip ring assembly and the rotating slip ring assembly is within 15mm.

[0024] In this embodiment, the wireless slip ring device in simplex mode has the following two optional layout designs for its wireless communication components on the fixed slip ring assembly and the rotating slip ring assembly: First layout design: such as Figure 2a As shown, the fixed slip ring assembly 2 has at least one transmitting module TX on its corresponding end face, and the rotating slip ring assembly 1 has at least one receiving module RX on its corresponding end face; the at least one transmitting module TX is arranged along the circumferential direction A1 on the corresponding end face of the fixed slip ring assembly 2; the at least one receiving module RX is arranged along the circumferential direction A2 on the corresponding end face of the rotating slip ring assembly 1; the circumferential directions A1 and A2 correspond to each other in the direction of the rotation axis, and the transmitting module TX on the circumferential direction A1 and the receiving module RX on the circumferential direction A2 can maintain communication at all times during rotation.

[0025] The second layout design: such as Figure 2bAs shown, the fixed slip ring assembly 2 has at least one receiving module RX on its corresponding end face, and the rotating slip ring assembly 1 has at least one transmitting module TX on its corresponding end face; the at least one receiving module RX is arranged along the circumferential direction A1 on the corresponding end face of the fixed slip ring assembly 2; the at least one transmitting module TX is arranged along the circumferential direction A2 on the corresponding end face of the rotating slip ring assembly 1; the circumferential directions A1 and A2 correspond to each other in the direction of the rotation axis, and the receiving module RX on the circumferential direction A1 and the transmitting module TX on the circumferential direction A2 can maintain communication at all times during rotation.

[0026] In the above layout design, the number of RF modules deployed can be increased, such as by increasing the number of RF modules arranged circumferentially; or the antenna design of the RF modules (a collective term for transmitting and receiving modules) can be improved (which can also be understood as wireless coverage), such as by using omnidirectional antennas, multi-antenna diversity, circularly polarized antennas, etc.; or other aspects, such as RF power / frequency performance control; by combining multiple design aspects, it is possible to ensure that the RF modules on the fixed slip ring assembly and the RF modules on the rotating slip ring assembly can maintain communication at all times during the rotation process.

[0027] In this embodiment, the wireless power supply component is arranged on the fixed slip ring component and the rotating slip ring component as follows, so as to realize the wireless transmission of electrical energy from the fixed slip ring component to the rotating slip ring component: The fixed slip ring assembly serves as the power supply transmitter, and the transmitter coil is provided on its corresponding end face; the transmitter coil nests the circumferential A1 within it; The rotating slip ring assembly serves as a power supply receiver, and a receiver coil is provided on its corresponding end face; the receiver coil nests the circumferential A2 within it.

[0028] Exemplary layout design diagrams of wireless power supply components and wireless communication components on fixed slip ring assemblies and rotary slip ring assemblies are shown below. Figure 3 As shown.

[0029] In some specific embodiments, the fixed slip ring assembly also integrates a wireless power supply primary-side control circuit (i.e., DC-DC primary-side circuit), a wireless data communication control circuit, and a protocol conversion circuit; the rotating slip ring assembly also integrates a wireless power supply secondary-side control circuit (i.e., DC-DC secondary-side circuit), a wireless data communication control circuit, and a protocol conversion circuit. By adjusting the protocol conversion circuit, it can support wireless slip ring applications in various scenarios, such as CAN, CAN-FD, Ethernet, EtherCAT, Profibus, RS422, RS485, RS232, etc.

[0030] The wireless power transmission principle of the wireless power supply component is as follows: An external power supply is connected to the fixed slip ring assembly, which serves as the power transmitter. The external power supply is converted into magnetic energy through the DC-DC primary circuit. The magnetic energy is then wirelessly transmitted to the rotating slip ring assembly, which serves as the power receiver, through the transmitter coil. The receiver coil on the rotating slip ring assembly receives the wireless magnetic energy and sends it to the DC-DC secondary circuit, where it is converted into electrical energy and stored in a capacitor for use by the load.

[0031] The layout design of the wireless power supply component in this embodiment adopts the outermost ring configuration scheme, that is, the wireless power supply component is configured in the outer ring of the two slip ring components, and there is a clear spatial boundary between it and the wireless full-duplex communication component located in the inner ring. This enables the "decoupling" design of power transmission and data transmission (outer ring power supply, inner ring communication), reducing mutual interference between the two; at the same time, it ensures power supply efficiency and communication quality and reliability.

[0032] Specifically, this embodiment of the wireless slip ring device, which integrates both wireless communication components and wireless power supply components, has the following significant advantages in terms of integrated deployment: (1) Effective isolation and reduced interference; There is physical isolation between the outer ring power transmission and the inner ring data transmission, which can effectively suppress the interference of electromagnetic fields on the data communication link; (2) Optimize magnetic field design; larger coil area can be deployed to achieve higher power transmission efficiency, longer effective distance and better heat dissipation; inner ring communication has the characteristics of centralized deployment, is less affected by external factors, and the routing distance of high frequency data signals is also shortened, which can achieve more stable, more reliable and more centralized communication. (3) Optimize structural design; wireless power supply components and wireless communication components can be designed, tested and maintained independently.

[0033] The wireless slip ring device provided in this embodiment arranges two slip ring assemblies end-to-end along a common axis, with the radio frequency module arranged in the inner ring of the end face and the wireless power supply assembly arranged in the outer ring of the end face. This enables high-speed, high-stability, and continuous wireless data transmission and wireless power transmission simultaneously between the two slip ring assemblies. This not only significantly improves the lifespan of the slip ring (the lifespan of non-contact slip rings is increased to over ten years) and enhances its robustness (constant impedance), but also reduces maintenance costs; furthermore, it features a simple structure and low cost.

[0034] In some specific embodiments of this example, for the wireless communication component, the number of radio frequency modules deployed will be used to ensure that the radio frequency modules on the fixed slip ring component and the radio frequency modules on the rotating slip ring component can maintain communication during rotation.

[0035] The following sections will provide a detailed description of the radio frequency module configuration schemes supported in the two layout designs of the aforementioned wireless communication components.

[0036] In the first layout design, the wireless communication component has the following three radio frequency module configuration schemes: Multi-TX and multi-RX configuration schemes: such as Figure 4a As shown, two or more transmitting modules TX are arranged on the circumferential A1 of the fixed slip ring assembly 2 to form a ring array of transmitting modules; correspondingly, two or more receiving modules RX are arranged on the circumferential A2 of the rotating slip ring assembly 1 to form a ring array of receiving modules.

[0037] Single TX multi-RX configuration scheme: such as Figure 4b As shown, the fixed slip ring assembly 2 has only one transmitting module TX on its circumferential A1; the corresponding rotating slip ring assembly 1 has two or more receiving modules RX arranged on its circumferential A2, forming a ring array of receiving modules.

[0038] Multi-TX single-RX configuration scheme: such as Figure 4c As shown, the fixed slip ring assembly 2 has two or more transmitting modules TX arranged on the circumferential A1 to form a transmitting module ring array; the corresponding rotating slip ring assembly 1 has only one receiving module RX on the circumferential A2.

[0039] In the second layout design, the wireless communication component also has the following four radio frequency module configuration schemes: Multi-TX and multi-RX configuration schemes: such as Figure 5a As shown, the fixed slip ring assembly 2 has two or more receiving modules RX arranged on the circumferential A1 to form a ring array of receiving and transmitting modules; correspondingly, the rotating slip ring assembly 1 has two or more transmitting modules TX arranged on the circumferential A2 to form a ring array of transmitting modules.

[0040] Multi-TX single-RX configuration scheme: such as Figure 5b As shown, the fixed slip ring assembly 2 has only one receiving module RX on its circumferential A1; the corresponding rotating slip ring assembly 1 has two or more transmitting modules TX arranged on its circumferential A2, forming a ring array of transmitting modules.

[0041] Single TX multi-RX configuration scheme: such as Figure 5c As shown, the fixed slip ring assembly 2 has two or more receiving modules RX arranged on the circumferential A1 to form a ring array of receiving modules; the corresponding rotating slip ring assembly 1 has only one transmitting module TX on the circumferential A2.

[0042] In the above-mentioned RF module configuration scheme, when configuring multiple RX or multiple TX, preferably, the multiple transmitting modules TX or receiving modules RX are evenly and equidistantly arranged in the corresponding circumferential direction to reduce signal interference, improve performance stability (consistent amplitude and phase characteristics of signals in each channel), and optimize transmission efficiency; optionally, the number of transmitting modules TX or receiving modules RX can be configured to be 3-20, preferably 4-8, depending on the circumference of the slip ring assembly and the signal coverage, communication quality, cost, power consumption, and other factors of the RF module.

[0043] As can be seen from the above, the first and second layout designs of the wireless communication components, based on the above-mentioned single TX multiple RX, multiple TX single RX, or multiple TX multiple RX configuration schemes, can ensure that the radio frequency module on the fixed slip ring component and the radio frequency module on the rotating slip ring component always maintain a corresponding relationship (there is always an overlapping area of ​​received / transmitted signal radiation) during the operation of the slip ring device, so as to realize that the wireless communication link between the fixed slip ring component and the rotating slip ring component always maintains communication stability and continuity.

[0044] In other specific embodiments of this example, to further ensure the continuity and reliable stability of wireless slip ring signal transmission, the RF modules on the fixed slip ring assembly and the rotating slip ring assembly will also employ one or more combinations of the following four designs to improve wireless coverage: Design 1: A ring array of transmitting modules (TX) arranged circumferentially on a fixed slip ring assembly, where the signal radiation ranges of adjacent transmitting modules (TX) overlap. This achieves a 360-degree uninterrupted continuous signal transmission area on the fixed slip ring assembly.

[0045] Design 2: In a fixed slip ring assembly, a ring array of receiving modules (RX) arranged circumferentially overlaps in the signal radiation range of adjacent receiving modules (RX). This achieves a 360-degree uninterrupted continuous signal reception area on the fixed slip ring assembly.

[0046] Design 3: In the rotating slip ring assembly, a ring array of transmitting modules (TX) arranged circumferentially forms a transmitting module ring with overlapping signal radiation ranges between adjacent transmitting modules (TX). This achieves a 360-degree uninterrupted continuous signal transmission area on the rotating slip ring assembly.

[0047] Design 4: In the rotating slip ring assembly, a ring array of receiving modules (RX) arranged circumferentially overlaps in the signal radiation range of adjacent receiving modules (RX). This achieves a 360-degree uninterrupted continuous signal reception area on the rotating slip ring assembly.

[0048] It is understood that the radiation range of a single transmitting / receiving module is limited, and there may be directional or signal coverage blind spots. By overlapping the coverage areas of adjacent RF modules, it can be ensured that in the first layout design described above, regardless of the angle to which the rotating slip ring assembly is rotated, at least one (or even more) transmitting modules' signals can be stably received by at least one (or even more) receiving modules on the fixed slip ring assembly. Similarly, in the second layout design described above, it can also be ensured that regardless of the angle to which the rotating slip ring assembly is rotated, at least one (or even more) receiving modules can stably receive signals emitted by at least one (or even more) transmitting modules on the fixed slip ring assembly. This completely eliminates communication dead spots, achieving truly high-quality, 360-degree uninterrupted communication transmission of simplex slip ring signals, significantly improving the reliability of the communication link; better meeting the stringent real-time communication requirements of high-precision equipment, and improving the practicality of the wireless slip ring device in this embodiment.

[0049] In some specific embodiments of this example, where neither the fixed slip ring assembly nor the rotating slip ring assembly is a hollow structure, such as a non-hollow disk structure or a polygonal structure, the wireless communication component, in its first and second layout designs, can also adopt a single TX single RX configuration scheme to achieve a wireless communication link between the fixed slip ring assembly and the rotating slip ring assembly with a minimalist structure.

[0050] Specifically, in the first layout design, the wireless communication component also has the following fourth radio frequency module configuration scheme: Single TX, single RX configuration scheme: such as Figure 4d As shown, when there is only one transmitting module TX on the circumferential A1 of the fixed slip ring assembly 2, the transmitting module TX is set close to the rotation axis; correspondingly, when there is only one receiving module RX on the circumferential A2 of the rotating slip ring assembly 1, the receiving module RX is set close to the rotation axis. Preferably, one of the transmitting modules TX is directly mounted on the rotation axis, and the corresponding receiving module RX is also mounted on the rotation axis. This module layout design is symmetrical, allowing the transmitting and receiving modules to correspond precisely, resulting in more reliable signal transmission performance.

[0051] In the second layout design, the wireless communication component also has the following fourth radio frequency module configuration scheme: Single TX, single RX configuration scheme: such as Figure 5dAs shown, when there is only one receiving module RX on the circumferential A1 of the fixed slip ring assembly 2, the receiving module RX is set close to the rotation axis; correspondingly, when there is only one transmitting module TX on the circumferential A2 of the rotating slip ring assembly 1, the transmitting module TX is set close to the rotation axis.

[0052] Preferably, one of the receiving modules RX is directly mounted on the rotation axis, and the corresponding transmitting module TX is also mounted on the rotation axis. This module layout design is symmetrical, allowing the transmitting and receiving modules to correspond precisely, resulting in more reliable signal transmission performance.

[0053] The single-T single-R configuration scheme specifically provided for non-hollow slip ring components can build wireless communication links with extremely simple RF module configuration, achieving simplified module design and precise correspondence; furthermore, while ensuring the wireless slip ring function, it saves the configuration of modules and logic gates (OR gates, which are required for one-to-many or many-to-many communication), significantly reducing system complexity, power consumption and cost.

[0054] It is worth noting that the transmitting module TX and receiving module RX involved in all embodiments of this utility model are preferably chip-level. Specifically, an AIP-packaged chip structure can be adopted; alternatively, a structure of wireless transceiver chip + board-level antenna can be used.

[0055] Among them, the AIP packaged chip structure solution has the RF antenna located inside the package structure, which makes the antenna more secure and stable; at the same time, although its verification cycle is longer, the cost required after verification will be much lower than other antenna structure solutions.

[0056] Among them, the wireless transceiver chip + board-level antenna structure has a relatively large board-level antenna size, but it has significant advantages such as low design difficulty, short verification cycle, low iteration cost and better antenna performance; it can be better suited for application scenarios that require support for higher signal rates and longer transmission distances.

[0057] Please see Figure 6 , 7a -b, Figure 6 A schematic diagram of an exemplary structure of a duplex wireless slip ring device provided for an embodiment of this utility model; Figure 7a -b are two schematic diagrams showing the third layout design of the wireless communication component in a specific embodiment of this utility model; Figure 8a -b are two schematic diagrams showing the fourth layout design of the wireless communication component in a specific embodiment of this utility model; Figure 7a -b and Figure 8a In -b, the transmitting module TX is simplified to T, and the receiving module RX is simplified to R.

[0058] This embodiment further extends the previous embodiment, providing a wireless slip ring device that supports full-duplex wireless communication and wireless power supply. The full-duplex mode can be either full-duplex or half-duplex.

[0059] The duplex mode wireless slip ring device provided in this embodiment, such as Figure 6 As shown, its wireless communication component 3 includes at least two transmitting modules TX and at least two receiving modules RX. In this embodiment, the wireless communication component can achieve bidirectional wireless full-duplex communication between the two slip ring components through either of the following two layout designs.

[0060] Specifically, the third and fourth layout designs of the wireless communication component on the fixed slip ring assembly and the rotating slip ring assembly are as follows: The third layout design: such as Figure 7a As shown in -b, based on the first layout design described above, the corresponding end face of the fixed slip ring assembly 2 is further provided with at least one receiving module RX, which is arranged along the circumferential direction B1 on the corresponding end face of the fixed slip ring assembly 2; the circumferential direction A1 and the circumferential direction B1 do not intersect and are nested; the corresponding end face of the rotating slip ring assembly 1 is further provided with at least one transmitting module TX, which is arranged along the circumferential direction B2 on the corresponding end face of the rotating slip ring assembly 1; the circumferential direction A2 and the circumferential direction B2 do not intersect and are nested; the circumferential direction B1 and the circumferential direction B2 correspond to each other in the direction of the rotation axis, and the circumferential direction A1 and the circumferential direction A2 correspond to each other in the direction of the rotation axis.

[0061] The fourth layout design: such as Figure 8a As shown in -b, based on the second layout design described above, the corresponding end face of the fixed slip ring assembly 2 is further provided with at least one transmitting module TX, which is arranged along the circumferential direction B1 on the corresponding end face of the fixed slip ring assembly 2; the circumferential direction A1 and the circumferential direction B1 do not intersect and are nested; the corresponding end face of the rotating slip ring assembly 1 is further provided with at least one receiving module RX, which is arranged along the circumferential direction B2 on the corresponding end face of the rotating slip ring assembly 1; the circumferential direction A2 and the circumferential direction B2 do not intersect and are nested; the circumferential direction B1 and the circumferential direction B2 correspond to each other in the direction of the rotation axis, and the circumferential direction A1 and the circumferential direction A2 correspond to each other in the direction of the rotation axis.

[0062] Based on the third or fourth layout design described above, during the operation of the slip ring device, it can ensure that the transmitting module on the fixed slip ring assembly and the receiving module on the rotating slip ring assembly maintain a corresponding relationship to realize the first wireless communication link from the fixed slip ring assembly to the rotating slip ring assembly; and it can ensure that the transmitting module on the rotating slip ring assembly and the receiving module on the fixed slip ring assembly maintain a corresponding relationship to realize the second wireless communication link from the rotating assembly to the fixed slip ring assembly; thereby realizing bidirectional wireless communication transmission between the two slip ring assemblies.

[0063] Based on the above, there is no specific limitation on whether the transmitting / receiving modules on the fixed slip ring assembly and the rotating slip ring assembly are arranged in the inner ring position or the outer ring position on their respective end faces.

[0064] Below are two optional multi-ring arrangement schemes for fixed slip ring assemblies and rotary slip ring assemblies on the face end: In the first specific embodiment, the nesting relationship between circumferential A1 and circumferential B1 of the fixed slip ring assembly is as follows: Circumferential A1 corresponds to the outer ring, and circumferential B1 corresponds to the inner ring; Consequently, the arrangement of the transmit / receive modules on the fixed slip ring assembly is as follows: In the third layout design, such as Figure 7a As shown, the transmitting modules TX are arranged along the circumferential direction A1 to form an outer ring transmitting module ring array, and the receiving modules RX are arranged along the circumferential direction B1 to form an inner ring receiving module ring array. In the fourth layout design, such as Figure 8a As shown, the receiving modules RX are arranged along the circumferential direction A1 to form an outer ring receiving module ring array, and the transmitting modules TX are arranged along the circumferential direction B1 to form an inner ring transmitting module ring array. Correspondingly, the nesting relationship between circumferential A2 and circumferential B2 of the rotary slip ring assembly is as follows: Circumferential A2 corresponds to the outer ring, and circumferential B2 corresponds to the inner ring; Consequently, the arrangement of the transmit / receive modules on the rotating slip ring assembly is as follows: In the third layout design, such as Figure 7a As shown, the outer ring of receiver modules (RX) is arranged along the circumferential direction A2 to form a ring array, and the inner ring of transmitter modules (TX) is arranged along the circumferential direction B2 to form a ring array. In the fourth layout design, such as Figure 8a As shown, the transmitting modules TX are arranged along the circumferential direction A2 to form an outer ring transmitting module ring array, and the receiving modules RX are arranged along the circumferential direction B2 to form an inner ring receiving module ring array.

[0065] In the second specific embodiment, the nesting relationship between circumferential A1 and circumferential B1 of the fixed slip ring assembly is as follows: Circumferential A1 corresponds to the inner ring, and circumferential B1 corresponds to the outer ring; Consequently, the arrangement of the transmit / receive modules on the fixed slip ring assembly is as follows: In the third layout design, such as Figure 7b As shown, the transmitting modules TX are arranged along the circumferential direction A1 to form an inner ring transmitting module ring array, and the receiving modules RX are arranged along the circumferential direction B1 to form an inner and outer ring receiving module ring array. In the fourth layout design, such as Figure 8b As shown, the receiving modules RX are arranged along the circumferential direction A1 to form an inner ring receiving module ring array; the transmitting modules TX are arranged along the circumferential direction B1 to form an outer ring transmitting module ring array.

[0066] Correspondingly, the nesting relationship between circumferential A2 and circumferential B2 of the rotary slip ring assembly is as follows: Circumferential A2 corresponds to the inner ring, and circumferential B2 corresponds to the outer ring.

[0067] Consequently, the arrangement of the transmit / receive modules on the rotating slip ring assembly is as follows: In the third layout design, such as Figure 7b As shown, the receiving modules RX are arranged along the circumferential direction A2 to form an inner ring receiving module ring array, and the transmitting modules TX are arranged along the circumferential direction B2 to form an outer ring transmitting module ring array. In the fourth layout design, such as Figure 8b As shown, the transmitting modules TX are arranged along the circumferential direction A2 to form an inner ring array of transmitting modules, and the receiving modules RX are arranged along the circumferential direction B2 to form an outer ring array of receiving modules.

[0068] The wireless slip ring device provided in this embodiment enables high-speed, high-stability, and continuous bidirectional wireless data transmission between the two slip ring components by arranging two slip ring assemblies end-to-end along a common axis and placing the radio frequency module on the corresponding end faces in the aforementioned multi-ring arrangement. This significantly improves the lifespan of the slip rings (the lifespan of non-contact slip rings is increased to more than ten years) and enhances their robustness (constant impedance); it also reduces maintenance costs; furthermore, it features a simple structure and low cost.

[0069] In some specific embodiments of this example, to further ensure the continuity and reliability of bidirectional wireless slip ring signal transmission, one or more combinations of the four designs described in the above embodiments can be used for the radio frequency modules on the fixed slip ring assembly and the rotating slip ring assembly in terms of wireless coverage. The specific details of designs one through four will not be elaborated here; please refer to the description in the previous embodiment for more information.

[0070] It is understandable that by using the above design to overlap the coverage areas of adjacent RF modules, it can be ensured that no matter what angle the rotating slip ring assembly rotates to, at least one (or even more) transmitting modules' signals can be stably received by at least one (or even more) receiving modules on the fixed slip ring assembly. Correspondingly, at least one (or even more) receiving modules can also stably receive signals emitted by at least one (or even more) transmitting modules on the fixed slip ring assembly. This completely eliminates communication dead zones, achieving truly high-quality, 360-degree uninterrupted bidirectional slip ring signal transmission, significantly improving the reliability of the bidirectional communication link; better meeting the stringent requirements of high-precision equipment for bidirectional real-time communication, and enhancing the practicality of the duplex mode wireless slip ring device in this embodiment.

[0071] Below are four exemplary preferred combination designs: The first preferred combination design is a combination of Design 1 and Design 2; thereby realizing a 360-degree uninterrupted continuous signal transmission area and a continuous signal reception area on the fixed slip ring assembly.

[0072] The second preferred combination design is a combination of Design 1 and Design 3; thereby achieving a 360-degree uninterrupted continuous signal reception area on the fixed slip ring assembly, and a 360-degree uninterrupted continuous signal reception area and a continuous signal transmission area on the rotating slip ring assembly.

[0073] The third preferred combination design is a combination of Design 4 and Design 2; thereby achieving a 360-degree uninterrupted continuous signal reception area on the rotating slip ring assembly and a 360-degree uninterrupted continuous signal reception area on the fixed slip ring assembly.

[0074] The fourth preferred design combination is a combination of Design 4 and Design 3; thereby achieving a 360-degree uninterrupted continuous signal reception area and a continuous signal transmission area on the rotating slip ring assembly.

[0075] The above-mentioned preferred combination design, through a simplified RF module layout, can achieve uninterrupted, stable and reliable bidirectional wireless slip ring signal transmission.

[0076] In some specific embodiments of this example, when the wireless communication component supporting duplex mode adopts the third and fourth layout designs, its radio frequency modules also support multiple configuration schemes in terms of deployment quantity.

[0077] The following sections provide detailed explanations of the radio frequency module configuration schemes supported in the third and fourth layout designs of the wireless communication components.

[0078] In the third layout design, the wireless communication component can realize the first wireless communication link (from the fixed slip ring component to the rotating slip ring component) through the three radio frequency module configuration schemes provided in the previous embodiment corresponding to the first layout design, namely TX multiple RX, single TX multiple RX, and multiple TX single 1RX configuration schemes. Meanwhile, the wireless communication component can also implement the second wireless communication link (from the rotating slip ring assembly to the fixed slip ring assembly) through any of the following three radio frequency module configuration schemes: Multi-TX and multi-RX configuration schemes: such as Figure 9a As shown, two or more transmitting modules TX are arranged on the circumferential B2 of the rotating slip ring assembly 1 to form a ring array of transmitting modules; correspondingly, two or more receiving modules RX are arranged on the circumferential B1 of the fixed slip ring assembly 2 to form a ring array of receiving modules.

[0079] Single TX multi-RX configuration scheme: such as Figure 9b As shown, the rotating slip ring assembly 1 has only one transmitting module TX on its circumferential B2, while the corresponding fixed slip ring assembly 2 has two or more receiving modules RX arranged on its circumferential B1, forming a ring array of receiving modules.

[0080] Multi-TX single-RX configuration scheme: such as Figure 9c As shown, the rotating slip ring assembly 1 has two or more transmitting modules TX arranged on the circumferential B2 to form a ring array of transmitting modules; the corresponding fixed slip ring assembly 2 has only one receiving module RX on the circumferential B1.

[0081] In the fourth layout design, the wireless communication component can realize the second wireless communication link (from the rotating slip ring component to the fixed slip ring component) through the three radio frequency module configuration schemes provided in the previous embodiment corresponding to the second layout design, namely TX multiple RX, single TX multiple RX, and multiple TX single 1RX configuration schemes. Meanwhile, the wireless communication component can implement the first wireless communication link (from the fixed slip ring assembly to the rotating slip ring assembly) through any of the following three radio frequency module configuration schemes: Multi-TX and multi-RX configuration schemes: such as Figure 10a As shown, two or more transmitting modules TX are arranged on the circumferential B1 of the fixed slip ring assembly 2 to form a ring array of transmitting modules; correspondingly, two or more receiving modules RX are arranged on the circumferential B2 of the rotating slip ring assembly 1 to form a ring array of receiving modules.

[0082] Single TX multi-RX configuration scheme: such as Figure 10b As shown, the fixed slip ring assembly 2 has only one transmitting module TX on its circumferential B1; the corresponding rotating slip ring assembly 1 has two or more receiving modules RX arranged on its circumferential B2, forming a ring array of receiving modules.

[0083] Multi-TX single-RX configuration scheme: such as Figure 10c As shown, the fixed slip ring assembly 2 has two or more transmitting modules TX arranged on the circumferential B1 to form a ring array of transmitting modules; the corresponding rotating slip ring assembly 1 has only one receiving module RX on the circumferential B2.

[0084] Similarly, in the radio frequency module configuration scheme described above in this embodiment, when multiple RX or multiple TX are configured, preferably, the multiple transmitting modules TX or receiving modules RX are evenly arranged at equal intervals in the corresponding circumferential direction; optionally, the number of transmitting modules TX or receiving modules RX can be configured to be 3-20, preferably 4-8.

[0085] The above-described specific implementation schemes provide three optional RF module quantity configuration schemes for the first wireless communication link and three optional RF module quantity configuration schemes for the second wireless communication link. Therefore, the duplex mode wireless slip ring device integrating the first and second wireless communication links in this embodiment has nine optional TX / RX configuration schemes in terms of RF module quantity configuration.

[0086] As can be seen, this embodiment, while ensuring uninterrupted, stable, and reliable bidirectional wireless slip ring signal transmission, provides multiple TX / RX configuration schemes for users to flexibly select and precisely match according to the performance, cost, and complexity requirements of different application scenarios. It not only possesses excellent flexibility and adaptability but also facilitates achieving the optimal cost-effectiveness ratio; it also boasts strong scalability and future practicality; furthermore, it enhances the robustness and reliability of the device.

[0087] In a preferred exemplary embodiment, such as Figure 7a As shown, the outer ring of the fixed slip ring assembly 2 consists of 8 transmitting modules TX evenly arranged along the circumferential direction A1, and the inner ring of the receiving module consists of 4 receiving modules RX evenly arranged along the circumferential direction B1. Correspondingly, the outer ring of the rotating slip ring assembly 1 consists of 8 receiving modules RX evenly arranged along the circumferential direction A2, and the inner ring of the transmitting module consists of 4 transmitting modules TX evenly arranged along the circumferential direction B2.

[0088] In some specific embodiments of this example, both the fixed slip ring assembly and the rotating slip ring assembly are not hollow structures, such as non-hollow disk structures or polygonal structures. When the wireless communication component implements a full-duplex communication mode, i.e., in the third and fourth layout designs, it can also adopt a single TX single RX configuration scheme to achieve a simplified structure for the first or second wireless communication link located in the inner ring.

[0089] Specifically, in the third layout design, the wireless communication component also has the following fourth radio frequency module configuration scheme: Single TX, single RX configuration scheme: such as Figure 9d As shown, when the fixed slip ring assembly 2 is located inside the nested relationship, the circumferential A1 is provided on the circumferential A1, and the one transmitting module TX is set close to the rotation axis; correspondingly, the circumferential A2 is also provided on the circumferential A2, and the one receiving module RX is set close to the rotation axis; so as to realize the construction of the first wireless communication link using a single TX single RX configuration scheme; like Figure 9e As shown, when the fixed slip ring assembly 2 is located inside the nested relationship, the circumferential B1 is provided with only one receiving module RX, which is set close to the rotation axis; correspondingly, the circumferential B2 is also provided with only one transmitting module TX, which is set close to the rotation axis; so as to realize the construction of the second wireless communication link using a single TX single RX configuration scheme.

[0090] In the fourth layout design, the wireless communication component also has the following fourth radio frequency module configuration scheme: Single TX, single RX configuration scheme: such as Figure 10d As shown, when the fixed slip ring assembly 2 is located inside the nested relationship, the circumferential A1 is provided, and the circumferential A1 is provided with only one receiving module RX, which is set close to the rotation axis; correspondingly, the circumferential A2 is also provided with only one transmitting module TX, which is set close to the rotation axis; so as to realize the construction of the second wireless communication link using a single TX single RX configuration scheme; like Figure 10e As shown, when the fixed slip ring assembly 2 is located inside the nested relationship, the circumferential B1 is provided, and the circumferential B1 is provided with only one transmitting module TX, which is set close to the rotation axis; correspondingly, the circumferential B2 is also provided with only one receiving module RX, which is set close to the rotation axis; so as to realize the construction of the first wireless communication link using a single TX single RX configuration scheme.

[0091] Preferably, one of the receiving modules RX is directly mounted on the rotation axis, and the corresponding transmitting module TX is also mounted on the rotation axis. This module layout design is symmetrical, allowing the transmitting and receiving modules to correspond precisely, resulting in more reliable signal transmission performance.

[0092] The aforementioned inner-loop single-T single-R configuration scheme, specifically designed for non-hollow slip ring devices, can still be implemented using a TTX-multiple-RX, multiple-TXTRX, or multiple-TX-multiple-RX configuration scheme for the outer ring. This RF module configuration scheme enables the construction of a wireless communication link in the inner ring with a minimalist RF module configuration, achieving simplified module design and precise correspondence. Furthermore, while ensuring the bidirectional wireless slip ring function, it saves on module and logic gate (OR gate, required for one-to-many or many-to-many communication) configurations, significantly reducing system complexity, power consumption, and cost.

[0093] Therefore, the wireless slip ring device provided in this embodiment can achieve high-speed, high-stability, and continuous wireless bidirectional data and wireless power transmission between the fixed slip ring assembly and the rotating slip ring assembly.

[0094] Please see Figure 11 , Figure 11 A schematic diagram of the wireless power supply component in the wireless slip ring device for wireless communication and wireless power supply provided in this embodiment of the utility model.

[0095] This embodiment further extends any of the above embodiments and also includes a magnetic shielding sheet and a ring-shaped magnetic core to provide shielding and isolation for the wireless power supply components.

[0096] Specifically, such as Figure 11 As shown, the annular magnetic core 7 is fixedly disposed on the corresponding end face of the fixed slip ring assembly 2, and the annular magnetic core 7 does not touch the rotating slip ring assembly 1; the wireless communication component (not shown), the annular magnetic core 7, and the wireless power supply component (transmitter coil 41 + receiver coil 42 in the figure) are nested sequentially from the inside out. The annular magnetic core 7 isolates the wireless power supply component and the wireless communication component on the fixed slip ring assembly 2.

[0097] The magnetic shielding sheet 6 is provided between the transmitting coil 41 and the fixed slip ring assembly 2; the magnetic shielding sheet 6 is also provided between the receiving coil 42 and the rotating slip ring assembly 1. By providing the magnetic shielding sheet, the electromagnetic induction efficiency of the coil can be optimized, electromagnetic signal attenuation can be prevented, the induced magnetic field can be concentrated, and the magnetic induction intensity can be increased.

[0098] In this embodiment, the combination of the magnetic shielding sheet and the ring-shaped magnetic core can not only reduce the leakage magnetic field between the transmitting coil and the receiving coil and improve the wireless power transmission efficiency, but also reduce the interference caused by the electromagnetic field generated by the coil to the wireless data communication link of the fixed slip ring assembly, the rotating slip ring assembly and the wireless communication assembly.

[0099] Please refer to 12a-d and Figure 13a -c, Figure 12a-d are schematic diagrams of four layout schemes of the ring-shaped absorbing shielding wall in specific embodiments of this utility model; Figure 13a -c are cross-sectional views of three exemplary structures with wave-absorbing shielding schemes in specific embodiments of this utility model.

[0100] This embodiment further extends the above-described duplex mode wireless slip ring device embodiment by including a circular ring-shaped absorbing shielding wall to provide shielding and isolation for the multi-ring structure of the wireless communication component.

[0101] The annular absorbing shield wall is installed on the corresponding end face of the slip ring assembly to isolate the inner and outer ring signals in the wireless communication assembly and eliminate wireless interference between rings.

[0102] In some specific embodiments, the absorbing shielding wall includes a ring of wireless signal shielding and a ring of absorbing material nested thereon. The former provides support and physical shielding, while the latter absorbs wireless signals. Preferably, the absorbing material is located in the inner ring, and the shielding ring is located in the outer ring. Here, the double-ring structure of the absorbing shielding wall effectively prevents wireless signals from passing through the wall or being reflected, ensuring signal transmission quality.

[0103] Specifically, the annular absorbing shielding wall described in this embodiment has the following four exemplary configuration options: In the first setup method, such as Figure 12a and Figure 13a As shown, the annular absorbing shielding wall 5 is provided between the circumferential A1 and the circumferential B1 on the fixed slip ring assembly 2; the annular absorbing shielding wall 5, the circumferential A1 and the circumferential B1 are nested, and the annular absorbing shielding wall 5 does not touch the rotating slip ring assembly 1 (not shown in the figure).

[0104] Here, circumferential A1, the ring-shaped absorbing shield, and circumferential B1 can be three rings nested sequentially from the inside out and spaced a certain distance apart; or they can be three rings nested in the reverse order.

[0105] In the second setting method, such as Figure 12b As shown, an annular absorbing shielding wall is provided between the circumferential A2 and the circumferential B2 on the rotating slip ring assembly 1; the annular absorbing shielding wall 5, the circumferential A2 and the circumferential B2 are nested, and the annular absorbing shielding wall 5 does not touch the fixed slip ring assembly 2 (not shown in the figure).

[0106] Here, circumferential A2, the ring-shaped microwave absorbing shield, and circumferential B2 can be three rings nested sequentially from the inside out and spaced a certain distance apart; or they can be three rings nested in the reverse order. The corresponding structural sectional view can be found in [reference needed]. Figure 13aTo understand this, the annular absorbing shielding wall is specifically installed on the rotating slip ring assembly.

[0107] It is understandable that the first and second setup methods mentioned above are single-sided retaining ring designs, such as... Figure 12a -b and Figure 13a As shown, only one annular absorbing shield wall 5 is set on the fixed slip ring assembly 2 or the rotating slip ring assembly 1, and the width (or height) of the annular absorbing shield wall is determined according to the distance between the two slip ring assemblies, so as to be as close as possible to the other slip ring assembly without touching the overall structure of the corresponding slip ring assembly, so as to prevent friction during rotation.

[0108] In the third setting method, such as Figure 12c and Figure 13b As shown, an annular absorbing shielding wall 5 is provided between circumferential A1 and circumferential B1 on the fixed slip ring assembly 2; the annular absorbing shielding wall 5, circumferential A1, and circumferential B1 are nested together; an annular absorbing shielding wall 5 is provided between circumferential A2 and circumferential B2 on the rotating slip ring assembly 1; the annular absorbing shielding wall 5, circumferential A2, and circumferential B2 are nested together. Specifically, the annular absorbing shielding wall 5 on the fixed slip ring assembly 2 is correspondingly provided with the annular absorbing shielding wall 5 on the rotating slip ring assembly 1, and the two are spaced apart by a preset distance; the preset distance is preferably greater than or equal to 0.5 mm.

[0109] In the fourth setting method, such as Figure 12d and Figure 13c As shown, an annular absorbing shielding wall 5 is provided between circumferential A1 and circumferential B1 on the fixed slip ring assembly 2; the annular absorbing shielding wall 5, circumferential A1, and circumferential B1 are nested together; an annular absorbing shielding wall 5 is provided between circumferential A2 and circumferential B2 on the rotating slip ring assembly 1; the annular absorbing shielding wall 5, circumferential A2, and circumferential B2 are nested together. In particular, such as Figure 13c As shown, the annular absorbing shielding wall 5 on the fixed slip ring assembly 2 and the annular absorbing shielding wall 5 on the rotating slip ring assembly 1 are nested, and the annular absorbing shielding wall 5 on the fixed slip ring assembly 2 does not touch the overall structure of the rotating slip ring assembly 1, and the annular absorbing shielding wall 5 on the rotating slip ring assembly 1 does not touch the overall structure of the fixed slip ring assembly 2.

[0110] Here, the nesting relationship between the annular absorbing shielding wall on the fixed slip ring assembly and the annular absorbing shielding wall on the rotating slip ring assembly is not specifically limited. For example, as Figure 13cAs shown, the annular absorbing shielding wall 5 on the rotating slip ring assembly 1 can be nested within the annular absorbing shielding wall 5 on the fixed slip ring assembly 2, i.e., the former is the inner ring and the latter is the outer ring. Alternatively, the nesting relationship can be reversed.

[0111] It is understandable that the third and fourth deployment schemes mentioned above, such as Figure 12b As shown in -c, an annular absorbing shielding wall 5 is respectively installed on the fixed slip ring assembly 2 and the rotating slip ring assembly 1. The nesting relationship between the rings is consistent with the optional nesting relationship provided in the first and second layout schemes above, and will not be elaborated further. Simultaneously, the width (or height) of the annular absorbing shielding wall is also determined based on the spacing between the two slip ring assemblies. It is worth noting that the two annular absorbing shielding walls on the two slip ring assemblies can be arranged symmetrically (e.g., ...). Figure 13b As shown), nested structures can also be used (e.g. Figure 13c (as shown); and, similarly, it should be as close as possible to but not touching the overall structure of the corresponding other slip ring assembly to prevent friction during rotation.

[0112] Please see Figure 14 , Figure 14 A schematic diagram of an exemplary structure of the wireless communication component of the wireless slip ring device provided in an embodiment of this utility model.

[0113] This embodiment is a further extension of any of the above embodiments, and also includes a communication board.

[0114] The communication board, as a circuit board for deploying the radio frequency module in the wireless communication component, can be designed as needed to realize a wireless transmitting circuit, a wireless receiving circuit, or a wireless transceiver circuit by designing the signal transmission direction of the radio frequency module on it.

[0115] Specifically, combined Figure 14 To understand: In the first layout design, at least one transmitting module on the fixed slip ring assembly 2, i.e., the ring array of transmitting modules arranged on the circumferential A1, is fixed on the fixed slip ring assembly 2 by a communication board 8; at least one receiving module on the rotating slip ring assembly 1, i.e., the ring array of receiving modules arranged on the circumferential A2, is fixed on the rotating slip ring assembly 1 by a communication board 8. In the second layout design, at least one receiving module on the fixed slip ring assembly 2, i.e., the ring array of receiving modules arranged on the circumferential direction A1, is fixed on the fixed slip ring assembly 2 by a communication board 8; at least one transmitting module on the rotating slip ring assembly 1, i.e., the ring array of transmitting modules arranged on the circumferential direction A2, is fixed on the rotating slip ring assembly 1 by a communication board 8. In the third layout design, at least one transmitting module (i.e., a ring array of transmitting modules arranged on the circumferential direction A1) and at least one receiving module (i.e., a ring array of receiving modules arranged on the circumferential direction B1) on the fixed slip ring assembly 2 are respectively fixed to the fixed slip ring assembly 2 via a communication board 8; at least one receiving module (i.e., a ring array of receiving modules arranged on the circumferential direction A2) and at least one transmitting module (i.e., a ring array of transmitting modules arranged on the circumferential direction B2) on the rotating slip ring assembly 1 are respectively fixed to the rotating slip ring assembly 1 via a communication board 8. In the fourth layout design, at least one transmitting module (i.e., a ring array of transmitting modules arranged on the circumferential B1) and at least one receiving module (i.e., a ring array of receiving modules arranged on the circumferential A1) on the fixed slip ring assembly 2 are respectively fixed on the fixed slip ring assembly 2 via a communication board 8; at least one receiving module (i.e., a ring array of receiving modules arranged on the circumferential B2) and at least one transmitting module (i.e., a ring array of transmitting modules arranged on the circumferential A2) on the rotating slip ring assembly 1 are respectively fixed on the rotating slip ring assembly 1 via a communication board 8.

[0116] Preferably, the communication board used to deploy the ring array of the transmit / receive modules adopts a ring communication board design that is adapted to the shape structure, so as to achieve the effect of simplifying the structure.

[0117] In some specific embodiments of this example, a connector 9 is also included.

[0118] Specifically, such as Figure 14 As shown, any communication board 8 can be selected to be fixed to the corresponding fixed slip ring assembly 2 or rotating slip ring assembly 1 via the connector 9, so that the communication board 8 and the corresponding fixed slip ring assembly 2 or rotating slip ring assembly 1 are at the optimal communication distance.

[0119] The connector serves two purposes: firstly, it enables electrical connection, allowing wireless data signals from the corresponding communication board to be transmitted to the corresponding slip ring assembly, and also transmitting power from the wireless power supply assembly to the corresponding slip ring assembly; secondly, it allows for flexible adjustment of the distance between the communication board and the corresponding slip ring assembly through height control, thereby regulating the unidirectional / bidirectional wireless data transmission distance between the two slip ring assemblies.

[0120] It is understandable that, as an optional accessory, the connector can be omitted when the optimal communication distance requirement for either a single or bidirectional wireless communication link can be met without raising the communication board; the corresponding communication board can be directly integrated into the corresponding slip ring assembly. This achieves a simplified structural design for the wireless slip ring assembly.

[0121] In a preferred exemplary embodiment, to simplify the structure while improving the stability and reliability of the rotary slip ring assembly, the communication board located on the inner ring of the rotary slip ring assembly is integrated into the rotary slip ring assembly using a merged design. Optionally, the communication board located on the outer ring of the rotary slip ring assembly may adopt the same merged design, or a multi-layer design with a height difference between the communication board on the inner ring and the corresponding end face of the rotary slip ring assembly.

[0122] In summary, the wireless slip ring device with wireless communication and wireless power supply provided by this utility model significantly improves the slip ring life (to more than ten years) by adopting non-contact wireless data / power transmission compared to the existing contact slip ring device. Compared to the traditional slip ring with a transmission rate of only tens of Mbps, it can easily break through the Gbps transmission rate to achieve high-speed transmission. In addition, it also has the characteristics of simple structure, low cost and lower maintenance cost.
