Figure 7 This is a rear view of a VR controller provided in an embodiment of the present invention. Figure 8 This is a schematic diagram of another VR controller provided in an embodiment of the present invention. Figure 9 This is a schematic diagram of the structure of the first circuit interface area provided in an embodiment of the present invention. Figure 10 This is a schematic diagram of the structure of the second circuit interface area provided in an embodiment of the present invention, as shown below. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the VR controller 100 includes a controller unit 101, a stylus unit 102, and a control unit 103. The controller unit 101 includes a housing 104 and a stylus receiving area 105 located on the housing 104. The stylus receiving area 105 accommodates the detachably mounted stylus unit 102. A first circuit interface area 106 is provided in the stylus receiving area 105, and a second circuit interface area 107 is provided in the stylus unit 102. The first circuit interface area 106 is provided with at least one first sub-circuit interface T1, and the second circuit interface area 107 is provided with at least one second sub-circuit interface T2. The first sub-circuit interface T1 and the second sub-circuit interface T2 are in corresponding contact and electrically connected. Both the first sub-circuit interface T1 and the second sub-circuit interface T2 are electrically connected to the control unit 103.

[0033] Both the controller unit 101 and the stylus unit 102 are operated by the user in the virtual world. The controller unit 101 is typically a 3DOF (degrees of freedom) controller, meaning it includes movement along the X, Y, and Z axes, enabling movement in three directions: up, down, left, right, and forward / backward. The stylus unit 102 is typically a 6DOF (degrees of freedom) stylus, enabling movement along the X, Y, and Z axes, plus three additional degrees of freedom related to rotation angles: rotation around the X, Y, and Z axes. This allows for comprehensive detection of spatial and angular information, enabling the stylus unit 102 to perform more precise operations such as drawing and writing in the virtual world. This increases the input methods available to the VR controller 100 and further enhances the user experience. Both the controller unit 101 and the stylus unit 102 are electrically connected to the control unit 103, ensuring that user operations on both units receive feedback from the external real world. The control unit 103 can be a microcontroller, a microcomputer that integrates a central processing unit, memory, timer, counter, and various input / output interfaces onto a single integrated circuit chip. It has functions such as processing instructions, executing operations, controlling time, and processing data. The handle unit 101 includes a housing 104 and a stylus receiving area 105 located on the housing 104. The stylus receiving area 105 accommodates a detachable stylus unit 102. The housing 104 can be designed according to actual design requirements. The stylus receiving area 105 is pre-designed in the housing 104 during the molding process, reducing the process flow and manufacturing costs. At the same time, it can accommodate the stylus unit 102 within the handle unit 101, avoiding the stylus unit 102 being independently set outside the handle unit 101, reducing the overall size of the VR handle 100 and reducing the risk of damage. To ensure both the controller unit 101 and the stylus unit 102 function properly, enabling the VR controller 100 to detect user operation information on 6DOF and reducing manufacturing costs, some structures in the controller unit 101 can be reused in the stylus unit 102 to maintain its functionality. Specifically, a first circuit interface area 106 is provided in the stylus receiving area 105, and a second circuit interface area 107 is provided in the stylus unit 102. The first circuit interface connects to the second circuit interface. The ports can be contacted and electrically connected. The first circuit interface area 106 is provided with multiple first sub-circuit interfaces T1, such as first sub-circuit interfaces T1-1 to T1-14 in the figure. The second circuit interface area 107 is provided with multiple second sub-circuit interfaces T2, such as second sub-circuit interfaces T2-1 to T2-14 in the figure. The first sub-circuit interfaces T1 and the second sub-circuit interfaces T2 are electrically connected to each other to ensure the connection between the stylus unit 102 and the handle unit 101, so as to realize the function reuse of the stylus unit 102 on the handle unit 101.At this time, it is also necessary to ensure that the functions of the first sub-circuit interface T1 and the second sub-circuit interface T2 correspond to the same function. The sub-circuit interface may include a power interface, an ID recognition interface, a connection success recognition port, etc., to ensure the effective use of the stylus unit 102 on the handle unit 101. Both the first sub-circuit interface T1 and the second sub-circuit interface T2 are electrically connected to the control unit 103 to ensure that the control unit 103 can recognize and record data on the external device whether the stylus unit 102 is placed in the stylus receiving area 105 or not. The sub-circuit interfaces may include power interfaces USB+ and USB-, indicator light interfaces LED+ and LED-, two-wire synchronous serial bus interfaces I2C_DATA, I2C_CLOCK, RST_KEY, INT, ID, and serial asynchronous transceiver protocol interfaces BLE_UART_TX and BLE_UART_RX. The number of first sub-circuit interfaces T1 in the first circuit interface area and the function of each first sub-circuit interface T1, as well as the number of second sub-circuit interfaces T2 in the second circuit interface area 107 and the function of each second sub-circuit interface T2, can all be selected according to actual design requirements. This embodiment of the invention does not impose specific limitations.

[0034] This invention provides an embodiment of a VR controller that simultaneously incorporates a controller unit and a stylus unit. The stylus unit is placed within the stylus receiving area of ​​the controller unit, which contains a first circuit interface area. The stylus unit itself has a second circuit interface area, which are in contact with and electrically connected to each other. This allows the stylus unit to utilize some functions of the controller unit, ensuring that both the controller unit and the stylus unit function normally. Furthermore, it avoids the need for additional, redundant circuitry, reducing manufacturing costs and guaranteeing the optimal performance of the VR controller.

[0035] Optional, continue to refer to Figures 1-10 The VR controller 100 also includes a light ring unit 108, which is electrically connected to the stylus unit 102; the light ring unit 108 and the controller unit 101 are detachably configured.

[0036] The VR controller 100 includes an LED ring unit 108, which is electrically connected to a stylus unit 102, meaning the LED ring unit 108 and stylus unit 102 are integrated. When the stylus unit 102 is placed in the stylus receiving area 105, the LED ring unit 108 contacts the controller unit 101. The controller unit 101 can have a groove structure, and the LED ring unit 108 can have a corresponding protrusion structure. The groove structure and the protrusion structure are correspondingly arranged, allowing the LED ring unit 108 to engage with the controller unit 101. For example, as shown in the figure, the operating area 112 of the controller unit 101 is rectangular. In this case, the corresponding LED ring unit 108 can be matched with a rectangular ring shape to match the controller unit 101, facilitating the detachable arrangement of the LED ring unit 108 and the controller unit 101. When the stylus unit 102 is not placed in the stylus receiving area 105, the light ring unit 108 and the stylus unit 102 move away from the stylus receiving area 105 at the same time. The light ring unit 108 enables the stylus unit 102 to interact with the external VR host, so that the external VR host can track the stylus unit 102 in real time, thereby meeting its internal algorithm requirements, receiving and presenting the user's operation in real time, and ensuring the user's experience.

[0037] Optional, continue to refer to Figures 1-10 The light ring unit 108 includes at least one infrared light-emitting diode 109, and the stylus unit 102 is also provided with a switch unit 110. The infrared light-emitting diode 109 is electrically connected to the control unit 103 through the switch unit 110.

[0038] The light ring unit 108 may be equipped with multiple infrared light-emitting diodes 109. In an exemplary embodiment of the present invention, the light ring unit 108 is equipped with 16 infrared light-emitting diodes 109. The number of infrared light-emitting diodes 109 can be selected according to actual design requirements, and the present invention does not impose a specific limitation. The light ring unit 108 may be equipped with a white LED, which is electrically connected to the second control unit 116 and can display the working status of the stylus unit 102. The specific function can be set according to actual needs. When the stylus is in operation, the infrared LED 109 illuminates and emits infrared light, causing the infrared sensors and other components in the external VR host to collect the infrared light, thereby tracking the movement trajectory of the stylus unit 102 in real time, performing corresponding calculations, and presenting the user's operations in the virtual world. The stylus unit 102 is also equipped with a switching unit 110, which can be a MOSFET or other components with switching functions. The MOSFET can include an NMOS transistor, which is turned on when a high-level signal is active and turned off when a low-level signal is active; or a PMOS transistor, which is turned on when a low-level signal is active and turned off when a high-level signal is active. In this application, an NMOS transistor is used as an example for demonstration. The specific selection of the switching unit 110 can be selected according to actual design requirements. This embodiment of the invention does not impose specific limitations. The infrared LED 109 unit is electrically connected to the control unit 103 via the switch unit 110. The control unit 103 includes a second control unit 116 located in the stylus unit 102. During the operation of the stylus unit 102, the switch unit 110 can be turned on to control the infrared LED 109 to light up, thereby ensuring that the external VR host can track the stylus unit 102 and that the VR controller 100 can respond and provide feedback to the user's operation normally.

[0039] Optional, continue to refer to Figures 1-10 The control unit 103 includes at least a first control unit 111, which is located inside the housing 104; the handle unit 101 also includes an operation area 112, which is located on the surface of the housing 104, and the operation area 112 is provided with at least one first button 113, which is electrically connected to the first control unit 111.

[0040] The control unit 103 includes a first control unit 111 located inside the housing 104 of the handle unit 101. The first control unit 111 can be a microprocessor. The handle unit 101 also includes an operation area 112 on the surface of the housing 104. The operation area 112 is equipped with multiple first buttons 113, which are typically defined as shortcut function keys or menu buttons frequently used by the user in the virtual world, facilitating user selection and improving operation speed. The shape and corresponding function of the first buttons 113 can be set and selected according to actual design requirements. For example, the figure shows five first buttons 113, including two different shapes. The first buttons 113 are electrically connected to the first control unit 111. When a user presses a first button 113, the first control unit 111 receives the corresponding signal change from the first button 113, which can then execute a specific user operation in the virtual world, providing convenience and improving the user experience.

[0041] Optional, continue to refer to Figures 1 to 7 The handle unit 101 also includes a trigger button 114, which is located on the surface of the housing 104 and is electrically connected to the first control unit 111.

[0042] The controller unit 101 has a trigger button 114 on its housing 104 surface. The trigger button 114 is electrically connected to the first control unit 111 in the controller unit 101, so that the user's control of the trigger button 114 can be received and responded to by the first control unit 111. For example, after a certain process or step is completed during the use of the VR controller 100, the user can press the trigger button 114 to enter the next process or step. Alternatively, the trigger button 114 can also be used as a shortcut key, directly ending the current process or step and returning to the main page when the trigger button 114 is pressed. The specific function of the trigger button 114 can be selected according to actual design requirements, and this embodiment of the invention does not impose any specific limitations.

[0043] Optional, continue to refer to Figure 8 The handle unit 101 also includes a displacement measuring unit 115, which is located inside the housing 104 and is electrically connected to the first control unit 111.

[0044] The handle unit 101 also includes a displacement measurement unit 115, located inside the housing 104. The displacement measurement unit 115 is electrically connected to the first control unit 111. The first control unit 111 collects displacement information in three directions in three-dimensional space from the displacement measurement unit 115, performs real-time analysis and calculation, and controls the system to display the data in the user's corresponding virtual world. The displacement measurement unit 115 can be an inertial measurement chip used to measure displacement, fulfilling the 3DOF (3-degree-of-flight) requirement of the handle unit 101. The handle unit 101 also includes a motor, electrically connected to the first control unit 111. Motor control enables the first control unit 111 to meet its performance requirements, such as vector control, spatial magnetic field orientation, coordinate decomposition, and PI control loops, reducing cost and power consumption while improving the control accuracy of the first control unit 111.

[0045] Optional, continue to refer to Figures 1-10 The control unit 103 includes at least a second control unit 116, and the stylus unit 102 includes a stylus housing 117. The second control unit 116 is located inside the stylus housing 117, and a second button 118 is provided on the surface of the stylus housing 117. The second button 118 is electrically connected to the second control unit 116.

[0046] The control unit 103 further includes a second control unit 116 located within the stylus unit 102. The stylus unit 102 includes a stylus housing 117, and the second control unit 116 is located inside the stylus housing 117. The second control unit 116 can be a microprocessor equipped with Bluetooth Low Energy. The second control unit 116 is provided with a signal output port, which is connected to an external FPC antenna via a coaxial cable to ensure signal transmission. A second button 118 is provided on the surface of the stylus housing 117. Since the second button 118 is electrically connected to the second control unit 116, the second control unit 116 inside the stylus unit 102 will receive signal changes from the second button 118. The second button 118 can be defined as a 2D or 3D switching function, text or font switching function, etc. The function corresponding to the second button 118 can be set according to actual needs, and this embodiment of the invention does not impose specific limitations. When the user uses the stylus unit 102 and presses the second button 118, the user's operation is executed in the virtual world, ensuring that the user's operation is responded to in a timely manner and ensuring the user experience.

[0047] Optional, continue to refer to Figures 1-10 The stylus unit 102 also includes a touch unit 119 and a sensor unit (not shown in the figure). The touch unit 119 is located on the surface of the stylus housing 117; the sensor unit is located inside the stylus housing 117, and the touch unit 119 is electrically connected to the second control unit 116 via the sensor unit.

[0048] The stylus unit 102 also includes a touch unit 119 located on the surface of the stylus housing 117 and a sensor unit located inside the stylus housing 117. The touch unit 119 is electrically connected to the control unit 103 via the sensor unit. The touch unit 119 can receive pressure signals applied by the user at the touch unit 119. Since the touch unit 119 is connected to the sensor unit, which can be a pressure sensor, the received pressure signal is converted into an electrical signal and transmitted to the second control unit 116. The second control unit 116 analyzes and processes the received electrical signal and adjusts the user's current operation in the corresponding virtual world. For example, the second control unit 116 can control the thickness of lines drawn by the stylus unit 102 in the virtual world based on the pressure applied by the user at the touch unit 119. The specific function corresponding to the magnitude of the pressure signal received at the touch unit 119 can be set according to actual needs, and this embodiment of the invention does not impose specific limitations. The stylus unit 102 may also include a memory, which is connected to the second control unit 116 via an SPI communication bus. The memory can be FLASH flash memory, and memory cell blocks, referred to as blocks, can be erased, written to, and reprogrammed. The stylus unit 102 may also include a crystal oscillator, which may include a 32MHz crystal oscillator and a 32kHz crystal oscillator. The crystal oscillator is used to generate oscillating current in the circuit to provide a clock signal to the second control unit 116. The stylus unit 102 may also include a power supply and a boost unit. The power supply can be an AA battery, and the boost unit is a BOOST boost circuit. The power supply is connected to the second control unit 116 through the boost unit and supplies power to the second control unit 116, enabling its normal operation.

[0049] Optional, continue to refer to Figures 1-10 The handle unit 101 is also equipped with an indicator light 120, which is electrically connected to the control unit 103. The indicator light 120 displays the connection status of the first sub-circuit interface T1 and the second sub-circuit interface T2.

[0050] The indicator light 120 is mounted on the controller unit 101 and can be located within the operation area 112, allowing users to directly observe the changes in the indicator light 120 and understand the current status of the VR controller 100. The indicator light 120 is electrically connected to the control unit 103 and can receive status information between the controller unit 101 and the stylus unit 102. Specifically, if the stylus unit 102 is located within the stylus receiving area 105 of the controller unit 101 and the first sub-circuit interface T1 and the second sub-circuit interface T2 are electrically connected, or if the stylus unit 102 has been removed from the stylus receiving area 105 of the controller unit 101 and the first sub-circuit interface T1 and the second sub-circuit interface T2 are disconnected, the indicator light 120 will display different colors depending on the connection status of the first sub-circuit interface T1 and the second sub-circuit interface T2, facilitating user judgment and improving the user experience. Meanwhile, since the stylus unit 102 is located in the stylus receiving area 105 of the handle unit 101, and since there are power interfaces in the first sub-circuit interface T1 and the second sub-circuit interface T2, the stylus unit 102 can be charged using the charging circuit in the handle unit 101, and the charging status of the stylus unit 102 can be displayed by changing the color of the indicator light 120.
