Description

Technical Field

[0001] This utility model relates to the technical field of smart devices, and in particular to a charging and communication rotating platform with controllable rotation angle. Background Technology

[0002] Existing rotating platforms have several shortcomings. Utility model patent CN209692384U proposes a charging base structure driven by a stepper motor, which allows for component angle adjustment and module replacement, but still suffers from the following defects: It cannot achieve infinite rotation; due to the lack of a slip ring structure, rotation is limited, preventing continuous power supply or signal transmission; communication capabilities are lacking, as a standardized communication interface is not provided, hindering data interaction with upper-level devices; module interfaces are non-universal, requiring physical plug-and-play for module replacement, resulting in poor compatibility; and upper-level device control is limited, as the absence of a communication link necessitates separate control buttons for modules such as fans, preventing unified control or remote command operation via the base.

[0003] The utility model patent CN215186004U uses a structure of conductive ring and spring pin (slip ring) to achieve rotational power supply, supporting the device rotation display function. It has certain technological progress, but it also has problems: it cannot achieve precise control of the rotation angle and status feedback; it does not have communication function, the slip ring is only used for power supply and cannot transmit control signals; the interface is non-standard, which is not conducive to modular docking; and the functional expandability is poor, limited to rotational charging display.

[0036] like Figure 1 - Figure 7 As shown, the present application provides a controllable rotation angle charging communication rotating platform 1, comprising:

[0037] The outer casing 10 has a communication and power supply integrated interface 20 on its top.

[0038] Slip ring assembly 30, the slip ring assembly 30 is disposed inside the housing 10, the slip ring assembly 30 includes slip ring upper plate 31 and slip ring bottom plate 32, the metal elastic pin 33 of the slip ring upper plate 31 is in communication with the concentric circular conductive ring 34 on the slip ring bottom plate 32;

[0039] A rotating support assembly 40 is installed below the top of the housing 10. The rotating support assembly 40 is used to support and drive the upper cover of the housing 10 to rotate. The upper end of the rotating support assembly 40 is fixedly connected to the upper plate 31 of the slip ring, and the rotating shaft 41 at the lower end passes through the bottom plate 32 of the slip ring. A permanent magnet 42 is embedded at the lower end of the rotating support assembly 40.

[0040] A stepper motor 50 is mounted on the bottom of the housing 10 and connected to the rotary support assembly 40 via a coupling 51.

[0041] A control circuit board 60 is installed at the bottom of the housing 10. A Hall sensor 61 is provided on the control circuit board 60. The Hall sensor 61 cooperates with the permanent magnet 42 to detect the angular position of the rotating platform and realize closed-loop control.

[0042] The outer shell 10 serves as the basic load-bearing structure of the platform, and the top is equipped with an integrated communication and power supply interface 20, which is used to accommodate all internal components and provide an installation reference for upper-level functional modules.

[0043] The outer casing 10 encloses the slip ring assembly 30, motor, and other internal components, isolating them from external dust, moisture, and physical impacts to ensure stable operation of the internal components. This design is particularly suitable for long-term use in various environments (such as office and industrial settings). The integrated communication and power supply interface 20 at the top is the core hub connecting the platform to upper-level devices. It achieves both power supply and data transmission functions through a single interface, avoiding the messy wiring problems caused by multiple interfaces scattered throughout. The outer casing 10 must possess sufficient strength (e.g., using ABS engineering plastic or metal) to support the weight of the upper-level modules and the centrifugal force during rotation, preventing overall structural deformation.

[0044] The slip ring assembly 30 is located inside the housing 10 and consists of an upper slip ring plate 31 and a lower slip ring plate 32. The core mating relationship is that "the metal elastic pin 33 of the upper slip ring plate 31 is connected to the concentric circular conductive ring 34 on the lower slip ring plate 32".

[0045] Traditional rotating platforms cannot achieve 360° continuous rotation due to cable entanglement. However, the slip ring assembly 30, through a sliding contact structure of "pin-conductive ring," maintains stable power and signal transmission throughout the rotation process. The pin is tightly fitted to the concentric circular conductive ring 34 and remains in contact as the upper slip ring plate 31 rotates, ensuring uninterrupted power and communication for the upper equipment during rotation. The separate design of the upper slip ring plate 31 and the base plate 13 clearly distinguishes the rotating part (the upper plate rotates with the platform) from the fixed part (the base plate 13 connects to the outer casing 10), ensuring rotational flexibility while achieving independent power and signal transmission through the partitioning of the conductive ring, avoiding mutual interference.

[0046] The rotating support assembly 40 is installed below the top of the housing 10. Its upper end is fixedly connected to the upper plate 31 of the slip ring, and its lower end rotating shaft 41 passes through the bottom plate 32 of the slip ring. A permanent magnet 42 is embedded in the lower end. Its core function is to "support and drive the upper cover 11 to rotate".

[0047] The rotating shaft 41 serves as the force transmission medium, connecting the upper slip ring plate 31 and the upper cover 11 at its upper end, and the lower end to the stepper motor 50 via a coupling 51. This transmits the motor's rotational power to the upper structure, enabling synchronous rotation of the upper cover 11 and the supporting module. The permanent magnet 42 embedded at the lower end is crucial for angle feedback. As it rotates with the rotating shaft 41, the change in its magnetic field is captured by the Hall sensor 61 on the control circuit board 60, providing real-time feedback of the current rotation angle and offering a data basis for precise angle control. The components must possess sufficient rigidity (e.g., using stainless steel) to support the weight of the upper module and resist torque during rotation, preventing rotational deviation or jamming due to deformation.

[0048] The stepper motor 50 is mounted on the bottom of the housing 10 and is connected to the rotary support assembly 40 via a coupling 51.

[0049] The stepper motor 50 features "pulse drive and angle controllable" characteristics. It rotates a fixed angle for each pulse signal received, and the rotation angle can be precisely adjusted by controlling the number of pulses, solving the problem of precise angle control in traditional motors. The coupling 51 buffers installation errors and vibrations between the motor and the rotating support assembly 40, ensuring smooth power transmission and preventing component wear or rotational jamming caused by rigid connections.

[0050] The closed-loop control logic is as follows: the motor is linked with the control circuit board 60, receives drive commands from the microprocessor (such as forward rotation, reverse rotation, and speed adjustment), and uses the angle feedback from the Hall sensor 61 to correct the rotation state in real time, thereby realizing closed-loop control of "command-execution-feedback".

[0051] The control circuit board 60 is mounted on the bottom of the housing 10, and its core configuration is a Hall sensor 61, which works in conjunction with the permanent magnet 42 at the lower end of the rotating support assembly 40. The Hall sensor 61 senses changes in the magnetic field of the permanent magnet 42 (such as magnetic field strength and direction), converts the physical angle into an electrical signal, and provides real-time feedback on the current position of the rotating platform with an accuracy of ±0.5°, providing data support for precise positioning.

[0052] The closed-loop control logic is as follows: After the circuit board receives the angle signal from the Hall sensor 61, it compares it with the preset target angle, calculates the adjustment amount through the built-in algorithm, drives the stepper motor 50 to correct the rotation, and ensures that the actual angle is consistent with the command, thus solving the angle drift problem under open-loop control.

[0053] The control circuit board 60 also integrates signal processing, motor drive and other functions (such as the microprocessor defined in the following claims), coordinates the operation of the housing 10 interface, slip ring assembly 30 and motor, realizes integrated control of power supply, communication and rotation, and improves the intelligence level of the platform.

[0054] This application forms a complete system of "mechanical support - power transmission - signal interaction - control feedback": the outer shell 10 provides protection and interface, the slip ring assembly 30 realizes rotational conduction, the rotational support assembly 40 transmits power and bears angle detection, the stepper motor 50 provides controllable power, and the control circuit board 60 realizes precise closed-loop control through the Hall sensor 61. The synergistic effect of each component fundamentally solves the problems of limited rotation, power supply / communication interruption, and ambiguous angle control in the prior art, providing core structural support for the charging and communication function of controllable rotation angle.

[0055] Furthermore, the integrated communication and power supply interface 20 is a USB Type-C interface 21 or a Pogo Pin interface 22.

[0056] The USB Type-C interface 21, as the current mainstream universal interface, supports reversible insertion, high-speed data transmission (up to 10Gbps), and high-power power supply (up to 100W), making it compatible with most smart devices (such as laptops and sensor modules). It can meet both power supply and communication needs without additional adapters. The Pogo Pin interface 22, on the other hand, is known for its high reliability, suitable for scenarios requiring frequent plugging and unplugging or vibration environments. Its tight contact ensures stable conduction over long-term use. The option of these two interfaces allows the platform to flexibly adapt to different application scenarios. For example, USB Type-C can be selected for office scenarios to improve versatility, while Pogo Pin can be selected for industrial scenarios to enhance durability. More importantly, the standardized interface breaks the limitation of "one device, one interface." Upper-layer functional modules (such as lighting modules and detection modules) can be quickly replaced through the same interface without redesigning the interface adapter structure, significantly reducing the difficulty and cost of module replacement, improving the platform's functional expandability, and providing users with a convenient "plug and play" experience.

[0057] Furthermore, the outer casing 10 includes an upper cover 11, a housing 12, and a bottom plate 13. The upper cover 11 is connected to the top of the housing 12, the bottom plate 13 is connected to the bottom of the housing 12, and the integrated communication and power supply interface 20 is connected to the upper cover 11.

[0058] Specifically, the top cover 11 is used to support the upper functional modules. As the direct load-bearing component of the upper functional modules, the top cover 11 needs to have sufficient strength. Its connection design with the top of the housing 12 can evenly transfer the weight of the upper modules to the housing 12, avoiding deformation caused by excessive local stress. The housing 12, as the intermediate layer, provides a closed installation space for the internal slip ring assembly 30, rotary support assembly 40, etc., protecting the components from dust and moisture corrosion, and reducing noise and vibration during rotation through the internal cavity structure. The bottom plate 13 is connected to the bottom of the housing 12, providing stable support for the bottom components such as the stepper motor 50 and control circuit board 60, and forming a complete protective barrier with the housing 12. The biggest advantage of this segmented design is the convenience of assembly and maintenance. During assembly, the internal components can be installed layer by layer (first install the motor and circuit board on the bottom plate 13, then install the slip ring and rotary support in the housing 12, and finally cover with the top cover 11). During maintenance, only the corresponding parts need to be disassembled, without the need for overall disassembly. In addition, the top cover 11 is specifically designed to support the upper-level modules, and its structural design can be flexibly adjusted according to the module size (such as adding anti-slip pads and positioning grooves), further improving the compatibility between the platform and the upper-level equipment.

[0059] Furthermore, the base plate 13 is provided with a connecting bracket 131, and the control circuit board 60 is connected to the connecting bracket 131.

[0060] The design of the connecting bracket 131 provides a dual guarantee of "rigid fixation and vibration isolation" for the control circuit board 60. The connecting bracket 131 is typically made of metal (such as aluminum alloy) and is rigidly connected to the base plate 13 by welding or screws. The control circuit board 60 is then fixed to the bracket with screws, forming a stable "base plate 13-bracket-circuit board" rigid structure. This effectively resists vibrations generated during motor operation, preventing components on the circuit board (such as the Hall sensor 61 and interface solder joints) from loosening or falling off due to vibration. Simultaneously, the bracket maintains a certain distance between the circuit board and the base plate 13, reducing the impact of electromagnetic interference from other components on the base plate 13 (such as the stepper motor 50) on the circuit board signals, ensuring stable transmission of signals such as angle detection and motor drive. Furthermore, this fixing method facilitates the removal and installation of the circuit board—during maintenance, simply loosening the screws on the bracket allows the circuit board to be removed without disassembling the base plate 13 or other components, significantly improving maintenance efficiency. For scenarios requiring long-term stable operation (such as 24-hour uninterrupted monitoring of a rotating platform), this robust installation structure can significantly reduce the failure rate and extend the equipment's lifespan.

[0061] Furthermore, the base plate 13 is provided with a connecting seat 132, and the connecting seat 132 has a placement groove 1321, in which the stepper motor 50 is placed.

[0062] The placement slot 1321 provides a dual guarantee of "physical protection and electromagnetic isolation" for the stepper motor 50. The placement slot 1321 of the connector 132 precisely matches the size of the stepper motor 50, firmly fixing the module and preventing it from shaking or colliding when the platform moves or vibrates, thus protecting fragile components such as capacitors and chips on the module. Simultaneously, the placement slot 1321 is typically made of insulating materials (such as engineering plastics) or has an internal shielding layer, reducing the interference of electromagnetic radiation generated by the stepper motor 50 during operation on the control circuit board 60. If the high-frequency switching signal of the stepper motor 50 leaks, it may interfere with the angle detection signal or communication signal of the Hall sensor 61. The isolation function of the placement slot 1321 effectively reduces this interference, ensuring the platform's control accuracy. Furthermore, the placement slot 1321 integrates the stepper motor 50 into a specific location on the base plate 13, making the internal wiring layout more organized (e.g., motor wires and power wires can run along the slot wall), avoiding the risk of short circuits caused by messy wiring, and improving the overall structural compactness and safety. For scenarios with high electromagnetic compatibility requirements (such as rotating platforms of medical equipment), this design ensures that the equipment complies with electromagnetic interference standards and operates stably.

[0063] Furthermore, the side wall of the housing 12 is provided with a connection port 121, and the edge of the bottom plate 13 is connected with a limiting buckle 133, which is inserted into the housing 12 and engages with the connection port 121.

[0064] The snap-fit ​​design achieves the dual advantages of "quick assembly and stable connection." During assembly, simply align the limiting snap-fit ​​133 on the edge of the base plate 13 with the connection port 121 on the side wall of the housing 12 and insert it. The snap-fit's elastic deformation achieves a tight fit, eliminating the need for tools and significantly reducing assembly time. Simultaneously, the uniform engagement force of the snap-fit ​​ensures consistent connection gaps between the housing 12 and the base plate 13, preventing deformation of the outer shell 10 due to uneven force. This connection method is also highly reliable in terms of stability—the snap-fit ​​is typically made of high-strength plastic or metal, exhibiting strong fatigue resistance and resisting loosening even under prolonged vibration, far superior to the anti-loosening effect of screw connections. Furthermore, during disassembly and maintenance, simply pressing the elastic part of the snap-fit ​​separates the housing 12 from the base plate 13 without removing screws, making operation convenient, especially suitable for scenarios requiring frequent opening of the outer shell 10 to inspect internal components (such as laboratory testing platforms). Overall, the snap-fit ​​design improves production efficiency while enhancing product durability and maintainability.

[0065] Furthermore, the side wall of the housing 12 is provided with a clearance opening 122, and the bottom plate 13 is provided with a connecting plate 134. When the bottom plate 13 is connected to the housing 12, the connecting plate 134 is correspondingly arranged to cover the clearance opening 122. The control circuit board 60 is connected to an operation interface 62 and a power interface 63. The operation interface 62 and the power interface 63 are located in the clearance opening 122 through the connecting plate 134.

[0066] The design of the clearance opening 122 and the connecting plate 134 achieves a balance between interface protection and ease of operation. The connecting plate 134 covers the clearance opening 122 of the housing 12, centrally arranging the operation interfaces 62 (such as debugging interfaces and communication interfaces) and power interfaces 63 of the control circuit board 60 on the connecting plate 134. This avoids direct exposure of the interfaces to the outside of the housing 12 (reducing dust and water droplet intrusion), and the material of the connecting plate 134 (such as hard plastic) provides physical protection against accidental collisions that could damage the interfaces. More importantly, the clearance opening 122 is typically located in an easily accessible position on the side or front of the housing 12, eliminating the need for users to bend over or flip the platform when plugging or unplugging power cords or connecting debugging equipment, significantly improving operational convenience. Furthermore, the centralized arrangement of interfaces makes wiring connections more organized, with all external cables entering from the same area, avoiding the problem of messy and tangled cables. This is particularly suitable for scenarios with multiple devices deployed together (such as multiple rotating display platforms in an exhibition hall), maintaining a clean environment. The cooperation between the connecting plate 134 and the housing 12 also ensures the airtightness of the housing 10, preventing the clearance opening 122 from becoming a channel for dust to enter, and further protecting the internal components.

[0067] Furthermore, the concentric circular conductive rings 34 on the slip ring base plate 32 include at least a power supply ring and a communication ring, wherein the power supply ring is used to transmit power and the communication ring is used to transmit data signals.

[0068] The power supply ring is specifically designed for transmitting power (such as powering upper-level devices or motors), capable of carrying large currents. Its structural design emphasizes low resistance and high stability, ensuring uninterrupted power supply. The communication ring, on the other hand, focuses on transmitting data signals (such as control commands and status feedback). Its surface treatment prioritizes low contact resistance and signal integrity, supporting high-speed data transmission (such as USB 3.0 and Ethernet signals). The two rings are physically separated and operate independently, fundamentally avoiding the impact of electromagnetic interference from the power supply current on communication signals. This solves the problems of packet loss and delays caused by the "mixed transmission of power and signals" in traditional slip rings. For example, in a rotating monitoring platform requiring real-time transmission of high-definition video, the independent design of the communication ring ensures stable video signal transmission, while the power supply ring continuously powers the camera without interference. Furthermore, the separate design facilitates optimization of each ring's performance for different needs. For instance, the power supply ring can be thickened to increase current carrying capacity, while the communication ring can have a coating to improve signal transmission efficiency, significantly enhancing the slip ring's applicability and reliability.

[0069] Furthermore, the rotating support assembly 40 includes a rotating part 43 and a connecting part 44 connected to each other. The rotating part 43 is used to support and drive the upper cover 11 to rotate. The rotating part 43 is fixedly connected to the upper plate 31 of the slip ring. The connecting part 44 passes through the bottom plate 32 of the slip ring. A permanent magnet 42 is embedded in the side wall of the connecting part 44.

[0070] The rotating part 43 is directly connected to the upper cover 11, responsible for supporting the weight of the upper functional module. Its structural design focuses on high strength (such as using alloy materials) to withstand large loads without deformation, ensuring the stability of the upper cover 11 and the upper module during rotation. The connecting part 44 passes through the slip ring base plate 32 and connects to the stepper motor 50, mainly responsible for transmitting rotational power. A bearing structure can be designed at the mating point with the slip ring base plate 32 to reduce frictional resistance during rotation, making the platform rotate more smoothly and reducing the load on the stepper motor 50. In addition, a permanent magnet 42 is embedded in the side wall of the connecting part 44. Its position design is more flexible, and the split structure allows the connecting part 44 to be processed independently, which facilitates precise control of the installation position of the permanent magnet 42, ensuring the matching accuracy with the Hall sensor 61 and improving the accuracy of angle detection. For example, in a rotating platform that supports heavier upper equipment (such as a small robotic arm), the high-strength design of the rotating part 43 ensures stable support, while the low-resistance design of the connecting part 44 ensures the precise positioning of the robotic arm during rotation. The two work together to improve the overall performance of the platform.

[0071] Furthermore, the control circuit board 60 is also equipped with a microprocessor, which is electrically connected to the stepper motor 50, the Hall sensor 61, and the integrated communication and power supply interface 20, respectively, and is used to receive angle control commands and drive the stepper motor 50 to rotate.

[0072] As the core, the microprocessor can receive external angle control commands (such as commands from a host computer via a communication interface). Combined with real-time angle information from the Hall sensor 61, it calculates the driving parameters of the stepper motor 50 (such as the number of rotation steps and speed) using algorithms, driving the motor to rotate precisely. This achieves closed-loop control of "command-detection-execution," solving the angle deviation problem caused by the decentralized control of traditional platforms. Simultaneously, the microprocessor can directly interact with the integrated communication and power supply interface 20, sending control commands (such as adjusting brightness or starting data acquisition) to upper-level devices or receiving status feedback, enabling unified management of upper-level modules. Users no longer need to operate each module individually, significantly improving ease of use. For example, in an interactive display platform, after a user sends the command "rotate 90° and turn on the lights," the microprocessor can simultaneously control the motor rotation and turn on the lighting module, enabling multi-device collaborative operation. Furthermore, the microprocessor can integrate fault detection functions (such as detecting power supply abnormalities or motor stall), promptly issuing alarms or taking protective measures (such as stopping rotation), improving the platform's safety and reliability. This centralized control design upgrades the platform from a "mechanical rotating device" to an "intelligent interaction center," significantly expanding its application scenarios.

It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model.
