Description

Technical Field

[0001] This utility model relates to the field of wireless communication technology, and in particular to a rotating connection structure. Background Technology

[0002] Current rotating transmission systems commonly employ technologies based on the principle of "optical communication." These solutions typically rely on complex and precise mechanical support structures, such as multi-bearing systems, to achieve the rotating transmission of optical signals. However, this design approach, which depends on precise mechanical fit, has the following inherent drawbacks: the complex bearings and mechanical structures make it difficult to reduce the overall size of the equipment and increase its weight, making it unsuitable for applications with limited space; the high-precision mechanical components also lead to high processing, assembly, and subsequent maintenance costs; at the same time, mechanical bearings are prone to wear under long-term high-speed operation, which not only limits the system's lifespan but also introduces mechanical vibration, making the precisely aligned optical path susceptible to factors such as vibration and temperature changes, resulting in signal drift or even interruption, making it difficult to guarantee long-term transmission stability.

[0022] Current rotating transmission systems commonly employ technologies based on the principle of "optical communication." These solutions typically rely on complex and precise mechanical support structures, such as multi-bearing systems, to achieve the rotating transmission of optical signals. However, this design approach, which depends on precise mechanical fit, has the following inherent drawbacks: the complex bearings and mechanical structures make it difficult to reduce the overall size of the equipment and increase its weight, making it unsuitable for applications with limited space; the high-precision mechanical components also lead to high processing, assembly, and subsequent maintenance costs; at the same time, mechanical bearings are prone to wear under long-term high-speed operation, which not only limits the system's lifespan but also introduces mechanical vibration, making the precisely aligned optical path susceptible to factors such as vibration and temperature changes, resulting in signal drift or even interruption, making it difficult to guarantee long-term transmission stability.

[0023] This utility model proposes a rotary connection structure.

[0024] Please see Figures 1 to 3 In one embodiment of this utility model, the rotary connection structure includes: The main housing 1 contains a data processing module 11 and a millimeter-wave wireless module 12 that are electrically connected to each other. The main housing 1 is also provided with a rotating connection port 13; Waveguide 14, one end of which is correspondingly set to the transmitting end of the millimeter-wave wireless module 12, and the other end is inserted along the center line of the rotating connector 13; The waveguide 14 contains a plastic waveguide 141 for receiving and transmitting radio frequency signals emitted by the millimeter-wave wireless module 12. The technical solution of this utility model integrates the millimeter-wave wireless module 12 and the data processing module 11 within the main housing 1, and utilizes the plastic waveguide 141 within the waveguide 14 for radio frequency signal transmission, achieving a non-contact rotational connection. This eliminates the complex multi-bearing mechanical system relied upon by traditional optical communication solutions, simplifying the overall mechanical structure and overcoming the inherent defects of large size, high cost, easy wear, and frequent maintenance caused by precision mechanical structures. The use of the plastic waveguide 141 combines high bandwidth transmission capability with physical flexibility, enabling the system to ensure stable data transmission while having higher fault tolerance for mechanical alignment errors, thereby improving the long-term operational stability and reliability of the system under conditions of vibration and temperature changes.

[0025] It should be noted that the rotary connection port 13 is used to rotatably connect to another rotary connection structure or external mechanical equipment. After the plastic waveguide 141 located in the rotary connection port 13 receives the external radio frequency signal, it is transmitted to the internal millimeter-wave wireless module 12 for reception, and the detection circuit 112 performs data processing.

[0026] It is understandable that when multiple rotary connection structures are connected, the two adjacent main housings 1 rotate relative to each other. Since the waveguide 14 passes through the center line of the rotary connection port 13, the waveguides 14 at the splicing points of different rotary connection structures are still aligned with each other, ensuring the stability of signal transmission. Moreover, the two waveguides 14 do not need to be in direct contact and will not rub against each other.

[0027] Among them, the plastic waveguide 141 has a high transmission rate and can stably communicate radio frequency signals at a rate of 3Gbps. It does not require high-precision docking during signal transmission and has strong stability. The plastic waveguide 141 has good flexibility, occupies a small volume, has a simple structure, and can greatly save costs. Furthermore, the plastic waveguide 141 placed inside the waveguide 14 can shield external signals and other interference.

[0028] like Figure 2 As shown, the millimeter-wave wireless module 12 includes a transceiver antenna 121, a radio frequency circuit 122 (RF), and a codec component 123 for converting electrical signals to radio frequency signals.

[0029] It should be noted that the transceiver antenna 121 includes a transmitting antenna (TXg, Transmit) and a receiving antenna (RXg, Receive). The codec component 123 includes a digital processing circuit that converts electrical signals into radio frequency signals through the millimeter-wave wireless module 12 and transmits them to the plastic waveguide 141, which then transmits the radio frequency signals out.

[0030] It is understood that the transceiver antenna 121, the radio frequency circuit 122, and the codec component 123 are electrically connected to each other.

[0031] like Figure 1 As shown, in one embodiment, the transceiver antenna 121 is an antenna in package (AiP), and the transceiver antenna 121, the radio frequency circuit 122 and the codec component 123 are integrated.

[0032] like Figure 2 As shown, in another embodiment, the transceiver antenna 121 is a board-level antenna, and the transceiver antenna 121 is located outside the radio frequency circuit 122 and the codec component 123.

[0033] like Figure 2 As shown, the data processing module 11 (FPGA) includes a signal generator 111 (GEN, Generator) and a detection circuit 112 (CHK, CHECK) for generating signals and processing received signals.

[0034] It is understood that by integrating the signal generator 111 and the detection circuit 112 into the data processing module 11, integrated closed-loop control of signal generation, transmission and reception processing is realized. This not only simplifies the system's dependence on external signal sources and improves the real-time performance and integrity of signal processing, but also enhances the real-time monitoring and fault tolerance of transmission quality through localized signal detection and analysis. Thus, the reliability of high-speed data transmission across rotating interfaces and the overall stability of the system can still be guaranteed under complex working conditions.

[0035] Furthermore, the data processing module 11 is capable of full-duplex communication.

[0036] Optionally, the millimeter-wave wireless module 12 and the plastic waveguide 141 can transmit signals without contact.

[0037] Understandably, since there is no physical contact between the millimeter-wave wireless module 12 and the plastic waveguide 141, mechanical friction and wear at the interface are avoided.

[0038] In some embodiments, the number of the rotary connectors 13 is one.

[0039] It is understood that some of the rotary connection structures that serve as the final end typically only require one rotary connection port 13 for connection with external mechanical equipment or another rotary connection structure.

[0040] In other embodiments, the number of the rotary connection ports 13 is multiple; The number of waveguides 14 corresponds to the number of rotary connectors 13.

[0041] It should be noted that by setting multiple rotating connection ports 13, synchronous signal relay and transmission from a single main housing 1 to multiple rotating axes or links is achieved. The number of rotating connection ports 13 can be selected according to actual needs, for example: In one embodiment, a main housing 1 is provided with two rotating connection ports 13. In this case, there are two waveguides 14, and the two waveguides 14 are respectively passed through the two rotating connection ports 13.

[0042] In another embodiment, one of the main housings 1 is provided with three of the rotating connection ports 13. In this case, the number of waveguides 14 is three, and the three waveguides 14 are respectively passed through the three rotating connection ports 13.

[0043] Optionally, the rotary connector 13 includes a first connecting portion 131 or a second connecting portion 132; The first connecting part 131 and the second connecting part 132 are adapted to each other to achieve modular splicing.

[0044] It should be noted that the first connecting part 131 is used to connect to the second connecting part 132 of another rotary connecting structure; The second connecting part 132 is used to connect to the first connecting part 131 of another rotary connecting structure.

[0045] Understandably, through the standardized first connecting part 131 and second connecting part 132, different rotary connection structures can be quickly and flexibly assembled like building blocks. Users can easily combine different numbers of channels according to actual needs to achieve configurations from single-channel to multi-channel, and even complex network topologies.

[0046] Preferably, one of the main housings 1 is provided with two rotating connection ports 13, and the two rotating connection ports 13 respectively include a first connection part 131 and a second connection part 132. Multiple rotating connection structures arranged in this way can facilitate users to splice them as needed.

[0047] It is understood that the rotating connection ports 13 provided in the same main housing 1 can all be either the first connection part 131 or the second connection part 132. In this case, it is only necessary to select another rotating connection structure that is provided with the corresponding rotating connection port 13.

[0048] For example, if both of the rotating connection ports 13 of the main housing 1 are the first connection part 131, then modular splicing can be achieved simply by using another rotating connection structure with a second connection part 132.

[0049] Optionally, the first connecting part 131 includes a drive rotor 1311, which is fixedly connected to the main housing 1; The second connection portion 132 includes a drive stator 1321, which is adapted to the drive rotor 1311.

[0050] Understandably, when the two main housings 1 are connected by the first connecting part 131 and the second connecting part 132, the relative rotation of the two main housings 1 can be achieved through the cooperation of the drive rotor 1311 and the drive stator 1321.

[0051] In some embodiments, the first connecting portion 131 further includes a first bearing 1312, and the second connecting portion 132 further includes a second bearing 1322, wherein the first bearing 1312 and the second bearing 1322 are respectively sleeved on both ends of the drive rotor 1311.

[0052] Optionally, the waveguide 14 passes through the rotation axis of the drive rotor 1311.

[0053] Optionally, the rotary connection port 13 further includes an axial limiting part 133.

[0054] It is understood that when the two rotary connection structures are spliced ​​together, the drive stator 1321 and the drive rotor 1311 can achieve relative rotation. The axial limiting part 133 can axially limit the two rotary connection structures to prevent them from separating.

[0055] like Figure 1 As shown, in some embodiments, the limiting part is a first limiting boss 1313 protruding from the circumference of the drive rotor 1311, and the second connecting part 132 is correspondingly provided with a limiting groove 1323.

[0056] It should be noted that the diameter of the limiting boss is larger than the inner diameter of the drive stator 1321, so it cannot be directly inserted. In this case, the drive stator 1321 and the main housing 1 are detachable structures. The drive stator 1321 includes a first stator body and a second stator body, and the main housing 1 includes a first housing and a second housing. The connection with the drive rotor 1311 is achieved by assembling the first stator body and the second stator body, and the installation is completed by assembling the first housing and the second housing.

[0057] It should be noted that the drive rotor 1311 is fixedly connected to the main housing 1 by bolts or other connecting parts.

[0058] like Figure 3 As shown, in some other embodiments, the axial limiting part 133 further includes a second limiting boss 1332 and a second clamping plate 1331. The second limiting boss 1332 is disposed on the periphery of the rotary connection port 13, and the second clamping plate 1331 is stepped and abuts against the second limiting boss 1332. When the two rotary connection structures are spliced, the two second clamping plates 1331 at the connection point fit together and form a limiting cavity. The two second limiting bosses 1332 at the connection point are located in the limiting cavity.

[0059] The two second clamping discs 1331 are fixed relative to each other by bolts or other connecting parts, which can prevent the two rotary connection structures from separating.

[0060] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
