[0020] This utility model proposes a control circuit for a hand controller, referring to... Figure 1 The cylindrical main body of the hand controller can rotate infinitely in both directions around its center axis; the control circuit is built into the main body of the hand controller and includes a microcontroller, a rotation detection module, a vibration module, a wireless communication module, a battery management module, a display module, and a multi-touch module, as well as a multi-touch backlight module corresponding to the multi-touch module;

[0021] The rotation detection module, vibration module, wireless communication module, battery management module, and display module are all electrically connected to the microcontroller; the multi-channel touch module is electrically connected to the microcontroller via the multi-channel touch backlight module.

[0022] The trigger end of the rotation detection module contacts the inner side of the main body of the hand controller;

[0023] The multi-channel touch module is compatible with multiple touch keys with different functions on the front of the main body of the hand controller.

[0024] In this embodiment, refer to Figure 2 The main body of the hand controller features a cylindrical design, with its diameter and length adjustable to suit various application needs (the circular area should ideally not exceed the size of an adult's palm). The side of the main body can rotate infinitely in both directions around its center. This design allows users to flexibly adjust the angle and direction of the hand controller as needed to achieve multiple operational functions. The main body can be made of high-strength plastic or metal alloy to improve its durability and lifespan.

[0025] The hand controller also features several touch buttons with different functions on its front, such as a menu button and control buttons that function similarly to the infinitely rotating buttons on the side of the main body.

[0026] The control circuit is the core of the hand controller, built into the main body of the hand controller, and mainly includes the following modules:

[0027] Microcontroller: As the core of the control circuit, the microcontroller is responsible for receiving data from various modules and processing this data to output corresponding control signals.

[0028] Rotation Detection Module: This module uses sensors (such as photoelectric sensors or potentiometers) to detect the angle and direction of rotation of the controller's main body. The trigger terminal of the rotation detection module is in direct contact with the inner side of the controller's main body to acquire rotation information in real time. This module transmits the detected rotation data to the microcontroller for analysis and processing.

[0029] Optionally, the trigger end of the rotation detection module can be a toggle-type bidirectional tactile switch, and the inner shape of the side of the hand controller body can be an inner ring gear. Through the interaction between the teeth of the gear and the toggle-type bidirectional tactile switch, the rotation detection module captures information on the rotation angle and direction, and transmits this information to the microcontroller in real time.

[0030] Vibration Module: The vibration module provides haptic feedback to enhance the user experience. Following instructions from the microcontroller, the vibration module can generate vibrations of varying intensities and durations (such as controlling the vibration of a built-in vibration motor) to provide feedback on the user's actions, for example, confirming a successful operation through vibration when a touch key is pressed.

[0031] Wireless communication module: Enables information exchange between the hand controller and external electronic control equipment. It supports multiple wireless protocols (such as Bluetooth, Wi-Fi, etc.), allowing the hand controller to wirelessly connect to other smart devices or systems.

[0032] Battery Management Module: The battery management module is responsible for monitoring and managing the built-in battery, ensuring the controller operates stably for extended periods. Its functions include battery status monitoring, charging management, and overcharge and over-discharge protection, ensuring safe and reliable use.

[0033] Display module: Used to display operating status, prompts, battery level, and the status of electronically controlled equipment. The screen brightness can be automatically adjusted by the microcontroller based on ambient light or set by the user to improve visibility and energy efficiency.

[0034] Multi-channel touch module: The multi-channel touch module is equipped with multiple touch keys, allowing users to perform various functions (such as power on / off, mode switching, etc.) by touching these keys. The functions of these touch keys can be preset according to actual needs.

[0035] Multi-channel touch backlight module: Each touch key corresponds to a backlight module, and the backlight can be adjusted via a microcontroller to provide visual feedback. Adjusting the backlight color and brightness can enhance the user's operating experience in low-light environments.

[0036] The various modules are electrically connected via circuit boards, enabling efficient communication between them. The rotation detection module, vibration module, wireless communication module, battery management module, and display module are all electrically connected to the microcontroller and share a power supply to ensure that each module receives sufficient operating voltage; while the multi-channel touch module is electrically connected to the microcontroller via the multi-channel touch backlight module.

[0037] The control principle of the hand controller:

[0038] (1) Rotation detection: When the user rotates the hand controller, the rotation detection module captures the information of the rotation angle and direction, and transmits the information to the microcontroller in real time.

[0039] (2) Touch operation: When the user presses any touch key on the multi-channel touch module, the touch module sends a touch signal to the microcontroller. After receiving the signal, the microcontroller performs the corresponding operation according to the preset function.

[0040] (3) Vibration feedback: After the user successfully operates, the microcontroller immediately instructs the vibration module to provide corresponding vibration feedback to confirm the operation.

[0041] (4) Visual information display: The display module updates the display content in real time, such as the current operation status or battery level, to provide users with clear information feedback.

[0042] (5) Communication: The microcontroller sends operation information to external devices through the wireless communication module and receives instructions from external devices, forming a two-way information interaction.

[0043] Taking smart tables and chairs as an example of electronically controlled devices controlled by a hand controller, users can adjust the height of the smart tables and chairs by rotating the hand controller, while the display module simultaneously displays the current height data of the smart tables and chairs:

[0044] When the user rotates the hand controller, the inner ring gear on the inner side of the hand controller's main body contacts the toggle-type bidirectional tactile switch of the rotation detection module. Through the interaction between the gear teeth and the toggle-type bidirectional tactile switch, the rotation detection module captures the rotation angle and direction information and transmits this information to the microcontroller in real time. After receiving the data from the rotation detection module, the microcontroller analyzes and calculates to determine the rotation angle. Subsequently, the microcontroller converts this rotation angle into a corresponding height adjustment command via the wireless communication module and sends it to the control box of the smart table and chair. After receiving the height adjustment command from the hand controller, the control box of the smart table and chair starts the motor or other drive device to adjust the height of the table and chair. At the same time, the smart table and chair will provide real-time feedback of the current height data to the hand controller. The hand controller's wireless communication module receives the height data fed back by the smart table and chair and updates the display content in real time through the display module to show the current height data of the smart table and chair. Users can also perform other functions through other touch keys on the multi-channel touch module, such as adjusting the tilt angle of the smart table and chair, switching working modes, and one-click height setting. Each successful operation instructs the vibration module to provide corresponding vibration feedback to confirm the user's operation.

[0045] Among them, the rotation detection module provides stepless and high-precision rotation data, which is suitable for control scenarios that require high sensitivity; the multi-touch module supports multi-touch, enhancing the flexibility of user operation and enabling quick operation; the backlight module optimizes the operating experience in low-light environments and enhances the visual effect; vibration feedback improves the user experience, reduces operational uncertainty, and ensures that every user operation receives immediate feedback.

[0046] In one embodiment, a multifunctional, efficient, and reliable hand controller control circuit is constructed, enabling flexible control of various electronically controlled devices. Its cylindrical body and infinitely rotating design, combined with multi-channel touch and vibration feedback, greatly enhance the user's interactive experience. It is suitable for applications in smart homes, industrial equipment, drones, and other fields, meeting the needs of modern human-computer interaction (and satisfying the control requirements of electronically controlled devices in numerous scenarios such as e-sports, offices, homes, and commerce).

[0047] In summary, the hand controller's control circuit integrates multiple circuit modules such as rotation detection, multi-channel touch control, vibration feedback, wireless communication, and battery management. It provides flexible stepless rotation in both directions and multi-functional touch operation, enabling precise control and rapid response. This significantly improves user experience and ease of operation, making it suitable for various application scenarios such as smart homes, industrial automation, and virtual reality.

This design not only improves visibility in different environments but also saves energy.

The LT8920 chip also boasts excellent wireless transmission performance, providing stable and high-speed data transmission to ensure accurate and timely control signals.

[0054] Ceramic antennas, with their small size, are ideal for integration into portable devices, especially in space-constrained environments like handheld controllers. Furthermore, ceramic antennas offer stable performance, high transmission efficiency, and good signal coverage. Compared to other types of antennas, ceramic antennas have better anti-interference capabilities and can operate stably in complex environments.

[0055] By integrating the LT8920 wireless communication chip and a ceramic antenna, this handheld controller's wireless communication module design not only enhances the device's communication capabilities, improves portability and efficiency, but also gives the controller a significant advantage in various application scenarios.

[0058] By touching these touch keys, users can perform different operations, increasing the diversity and flexibility of control.

[0059] The 4-channel touch backlight module provides independent backlighting for each touch key, enhancing visual effects, especially in low-light environments where touch feedback is more pronounced. The backlight module can also adjust brightness and color based on the actual touch status, improving the user experience.

[0060] In one embodiment, based on the above embodiments, referring to Figure 3 The control circuit also includes a memory electrically connected to the microcontroller, and a USB TYPE-C port for program upgrades and debugging.
