[0002] Current virtual reality (VR) devices include battery-powered and integrated devices that are not separable in structure and do not support plugging and unplugging or self-replacement of accessories. They also include devices powered by external battery packs, which support plugging and unplugging of power supplies and self-replacement of power accessories, but have the disadvantage of external battery packs and power cords.

[0003] The above-mentioned VR devices are all turned on by pressing the power button of the VR device. However, after the VR device is turned on, the power supply component is in a power consumption state whether the VR device is in use or not, which will cause the battery in the power supply component to be over-discharged and unsafe. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a virtual reality VR device, which can solve the unsafe problem that when the virtual reality VR device is idle, the power supply component is in a power consumption state, causing the battery therein to be over-discharged.

[0005] In a first aspect, an embodiment of the present application provides a virtual reality VR device, comprising: a power supply component and a head-mounted display component; wherein the power supply component is pluggable to the head-mounted display component; when the power supply component is inserted into the head-mounted display component, the power supply component supplies power to the head-mounted display component; when the power supply component is unplugged from the head-mounted display component, the power supply component stops supplying power to the head-mounted display component.

[0006] The virtual reality VR device provided by the embodiment of the present application includes a power supply component and a head display component.

[0019] The following is a detailed description of the pluggable power supply assembly and electronic device provided in the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0020] Figure 1 FIG. 1 is a schematic diagram showing the structure of a VR device provided in an embodiment of the present application. Figure 1 The VR device 100 includes a power supply component 11 and a head display component 12, wherein the power supply component 11 is pluggable and connected to the head display component 12. When the power supply component 11 is inserted into the head display component 12, the power supply component 11 supplies power to the head display component 12. When the power supply component 11 is unplugged from the head display component 12, the power supply component 11 stops supplying power to the head display component 12.

[0021] In one example, the power supply assembly 11 of the VR device 100 can be integrated into the pluggable temple 110, see Figure 1 The visible part of the power supply assembly 11 includes a charging interface 111, which includes a battery 112. The connection interface 13 between the pluggable temple 110 and the head display assembly 12 can adopt a hidden USB Type-C3.0 interface.

[0022] Figure 2 FIG. 1 shows a circuit diagram of a power supply component of a VR device provided in an embodiment of the present application in an implementation manner, see FIG. Figure 2 The power supply component 200 may include a microcontroller unit (MCU) 21, a first power management chip (PMIC) 22 and a battery 23; the microcontroller MCU 21 includes a general purpose input / output (GPIO) pin 211 and a configuration channel (CC) pin 212; the microcontroller MCU 21 is connected to the first power management chip PMIC 22, and the first power management chip PMIC 22 is connected to the battery 23.

[0023] The microcontroller MCU 21 is used to detect the voltage of the general input / output GPIO pin 211; the first power management chip PMIC 22 is used to control the battery 23 to supply power to the head display component when the voltage of the general input / output GPIO pin 211 changes.

[0024] The microcontroller MCU 21 is further used to detect the voltage of the configuration channel CC pin 212; the first power management chip PMIC 22 is further used to disconnect the battery 23 from supplying power to the head display component when the voltage of the configuration channel CC pin 212 changes.

[0025] In the embodiment of the present application, when the power supply assembly is inserted into the head display assembly, the general input / output GPIO pin 211 of the microcontroller MCU 21 of the power supply assembly 200 is always powered, for example, with a power supply voltage (V1), and the electronic load of the head display assembly is first powered by the general input / output GPIO pin 211, so that the voltage of the general input / output GPIO pin 211 generates a short falling edge, see Figure 3 The signal waveform diagram shown in FIG. 1 is shown in FIG. 1 , thereby triggering the interrupt wake-up of the microcontroller MCU 21. At this time, the microcontroller MCU 21 of the power supply component 200 can detect that the voltage of the general input / output GPIO pin 211 changes, such as generating a falling edge, to determine that the current power supply component is inserted into the head display component, so that the first power management chip PMIC22 of the power supply component controls the battery 23 to supply power to the head display component, so that the power supply component exits the low power consumption mode and meets more power supply requirements of the head display component.

[0026] When the power supply component is unplugged from the head display component, the voltage of the configuration channel CC pin 212 of the microcontroller MCU 21 of the power supply component will change. At this time, the microcontroller MCU 21 of the power supply component can detect the change in the voltage of the configuration channel CC pin 212 to determine that the current power supply component is unplugged from the head display component, so that the first power management chip PMIC 22 of the power supply component disconnects the power supply of the battery 23 to the head display component, so that the power supply component enters a low power consumption mode, reducing the power consumption of the power supply component when the head display component is not in use. It is achieved that when the power supply component is inserted into the head display component without a power button, the head display component can be automatically powered on, and when the power supply component is unplugged from the head display component, the power supply component can enter a low power consumption mode, reducing the power consumption of the power supply component when the head display component is idle and solving the unsafe problem of over-discharge of the battery in the power supply component.

[0027] Figure 4 FIG. 1 shows a circuit diagram of a VR device provided in an embodiment of the present application in an implementation manner, see Figure 4 The VR device 400 includes the power supply component 200 and the head display component 300 as described above.

[0028] Among them, the head display component 300 includes a main control chip (Central Processing Unit, CPU) 31 and a second power management chip PMIC 32; the main control chip CPU 31 is connected to the second power management chip PMIC 32; the microcontroller MCU 21 of the power supply component 200 is connected to the main control chip CPU 31; the first power management chip PMIC 22 of the power supply component 200 is connected to the second power management chip PMIC 32.

[0029] In the VR device 400 provided in the embodiment of the present application, the power supply component 200 is inserted into the head display component 300 to supply power to the head display component 300, and the VR device 400 works. The microcontroller MCU 21 of the power supply component 200 detects the voltage of the general input / output GPIO pin 211, determines that the voltage of the general input / output GPIO pin 211 changes, such as generating a falling edge, and the first power management chip PMIC 22 controls the battery 23 to supply power to the head display component 300, so that the power supply component 200 is inserted into the head display component 300 without a power button, and the head display component 300 can be automatically powered on.

[0030] It should be noted that Figure 4 The head display assembly in the embodiment shown is limited by the platform design. The head display assembly 300 needs to have a small capacity battery to start up. The setting of the small capacity battery is as follows: Figure 4 shown.

[0031] Figure 5 FIG. 1 shows a circuit diagram of another VR device provided in an embodiment of the present application in an implementation manner, see FIG. Figure 5 The head display component 300 may further include a second test resistor 33; the second test resistor 33 is connected to the second power management chip PMIC 32. The power supply component 200 may further include a first test resistor 24.

[0032] The microcontroller MCU 21 is further used to detect the first voltage of the first test resistor 24 and obtain the second voltage of the second test resistor 33 of the head display component 300; and when it is determined that the first voltage or the second voltage does not belong to a preset voltage range, stop supplying power to the head display component 300.

[0033] In the embodiment of the present application, when the power supply component 200 is inserted into the head display component 300, the microcontroller MCU21 of the power supply component first powers the electronic load of the head display component 300 through the general input / output GPIO pin 211, and the electronic load includes a second test resistor 33. At this time, the first test resistor 24 of the power supply component 200 and the second test resistor 33 of the head display component 300 both have voltages, the microcontroller MCU 21 of the power supply component 200 detects the first voltage of the first test resistor 24, the second power management chip PMIC 32 of the head display component 300 detects the second voltage of the second test resistor 33, and sends the detected second voltage of the second test resistor 33 to the main control chip CPU 31 of the head display component 300, and then the main control chip CPU 31 sends the second voltage to the microcontroller MCU 21 of the power supply component 200, so that the microcontroller MCU 21 judges the second voltage of the second test resistor 33 and the first voltage of the first test resistor 24 in the power supply component 200, and when it is determined that the first voltage or the second voltage does not belong to the preset voltage range, the power supply component 200 stops supplying power to the head display component 300. By judging the first voltage of the first test resistor of the power supply component and the second voltage of the second test resistor of the head display component, the identifier (ID) of the head display component 300 into which the power supply component 200 is inserted is identified to judge whether the head display component 300 is compatible with the power supply component 200, thereby avoiding other unknown problems caused by the connection of other non-standard devices to the power supply component, such as damage to other non-standard devices, and improving the safety of VR devices.

[0034] Figure 6 FIG. 1 shows a circuit diagram of another VR device provided in an embodiment of the present application in an implementation manner, see FIG. Figure 6 The first power management chip PMIC 22 of the power component 200 of the VR device 400 includes a first VBAT pin 221, a VPH pin 222 and a switch tube 223; the first power management chip PMIC 22 is connected to the battery 23 through the first VBAT pin 221.

[0035] The switch tube 223 is used to open or close the path between the first VBAT pin 221 and the VPH pin 222 ; the microcontroller MCU 21 is also used to control the first power management chip PMIC 22 to close or open the switch tube 223 .

[0036] In the VR device provided in the embodiment of the present application, when the power supply component 200 is inserted into the head display component 300, the microcontroller MCU 21 of the power supply component 200 first powers the electronic load of the head display component 300 through the general input / output GPIO pin 211. When the microcontroller MCU 21 of the power supply component 200 detects that the voltage of the general input / output GPIO pin 211 changes, such as a falling edge, it can be determined that the power supply component 200 is inserted into the head display component 300, so that the microcontroller MCU 21 controls the first power management chip PMIC 22 to close the switch tube 223, so that the path between the first VBAT pin 221 and the VPH pin 222 is turned on, and the power supply component 200 outputs the battery voltage to the head display component 300, so that the first power management chip PMIC 22 of the power supply component 200 controls the battery 23 to power the head display component 300, and the power supply component 200 exits the low power consumption mode.

[0037] When the power supply component 200 is unplugged from the head display component 300, the microcontroller MCU 21 of the power supply component 200 detects that the voltage of the configuration channel CC pin 212 changes, and can determine that the power supply component 200 is unplugged from the head display component 300. Therefore, after a certain delay, the microcontroller MCU 21 controls the first power management chip PMIC 22 to disconnect the switch tube 223, so that the path between the first VBAT pin 221 and the VPH pin 222 is cut off, and the power supply component 200 no longer outputs the battery voltage to the head display component 300, so that the first power management chip PMIC 22 of the power supply component 200 disconnects the battery 23 from supplying power to the head display component 300, and the power supply component 200 enters a low power consumption mode.

[0038] Figure 7 FIG. 1 shows a circuit diagram of another VR device provided in an embodiment of the present application in an implementation manner, see FIG. Figure 7 The second power management chip PMIC 32 of the head display component 300 includes a second VBAT pin 321; the second VBAT pin 321 is connected to the VPH pin 222 of the power supply component 200.

[0039] In the embodiment of the present application, Figure 4 , Figure 5 and Figure 6The difference between the head display assembly 300 in the illustrated embodiment is that, in order to reduce the weight of the head display assembly 300 and avoid the safety problem of battery overheating, the small-capacity battery of the head display assembly 300 is removed in this embodiment, and the second VBAT pin 321 of the second power management chip PMIC 32 is connected to the VPH pin 222 of the power supply assembly 200, so that the power supply assembly 200 supplies power to the head display assembly 300. It is achieved that on the basis of removing the small-capacity battery of the head display assembly 300 to reduce the weight of the head display assembly, the power supply assembly 200 can still be inserted into the head display assembly 300 without a power button, and the head display assembly 300 can be automatically powered on.

[0040] Figure 8 FIG. 1 shows a circuit diagram of another VR device provided in an embodiment of the present application in an implementation manner, see FIG. Figure 8 The power supply component 200 of the VR device 400 may further include a first voltage converter (Direct Current to Direct Current Converter, DCDC) 25; the first voltage converter DCDC 25 is connected to the battery 23.

[0041] The first voltage converter DCDC 25 is used to convert the voltage of the battery 23 into a preset standard voltage.

[0042] In the embodiments of the present application, when the first power management chip PMIC 22 of the power supply component 200 controls the battery 23 to supply power to the head display component 300, the voltage of the battery 23 is first converted into a preset standard voltage, such as a standard Type-C interface voltage, by the first voltage converter DCDC25 in the power supply component 200, and then the preset standard voltage is output to the head display component 300.

[0043] In addition, since the first voltage converter DCDC 25 has efficiency loss, in order to improve the power supply efficiency of the power supply component 200, the microcontroller MCU 21 controls the first power management chip PMIC 22 to close the switch tube 223, so that the path between the first VBAT pin 221 and the VPH pin 222 is turned on, and the power supply component 200 outputs the voltage of the battery 23 to the head display component 300. The power supply component 200 first outputs the voltage (V1) of the general purpose input / output GPIO pin 211 of the microcontroller MCU 21 to the head display component 300, and then when the voltage of the general purpose input / output GPIO pin generates a falling edge, the voltage of the battery 23 is converted into a preset standard voltage (V2) through the first voltage converter DCDC 25. Then, based on the purpose of improving power supply efficiency or meeting the power supply demand of the head display component 300, the microcontroller MCU 21 of the power supply component 200 controls the first power management chip PMIC 22 to close the switch tube 223, and conducts the path between the first VBAT pin 221 and the VPH pin 222, so as to directly output the voltage (V3) of the battery 23 to the head display component 300, see Fig. 9 The signal waveform diagram of the step-by-step power-on realizes the step-by-step power-on of the head-mounted display component 300 by the power supply component 200, and can avoid surge phenomenon and damage to the head-mounted display component during the power supply component 200 to the head-mounted display component 300.

[0044] In one implementation, see Figure 8 The head display component 300 in the VR device 400 also includes a second voltage converter DCDC 34; one end of the second voltage converter DCDC 34 is connected to the first power management chip PMIC 22, and the other end of the second voltage converter DCDC 34 is connected to the second power management chip PMIC 32.

[0045] In an embodiment of the present application, the power supply component 200 supplies power to the head display component 300. The power supply voltage output from the power supply component 200 is converted into a preset standard voltage, such as a standard Type-C interface voltage, by a second voltage converter DCDC 34, and then transmitted to the second power management chip PMIC 32, so that the second power management chip PMIC 32 detects the power supply voltage to determine that the power supply component 200 has been inserted and is supplying power.

[0046] Optional, such as Figure 8As shown, the power supply component 200 in the VR device 400 provided in the embodiment of the present application may also include a diode D1 or a switch load to prevent the supply voltage of the battery 23 or the output voltage of the first voltage converter DCDC 25 from being higher than the voltage of the general input / output GPIO pin 211, thereby preventing backflow and damaging the general input / output GPIO pin 211 of the microcontroller MCU 21.

[0047] Optional, such as Figure 8 As shown, the head display component 300 in the VR device 400 provided in the embodiment of the present application may also include a diode D2 or a switch load to prevent the second power management chip PMIC 32 from forming a self-loop.

[0048] In one implementation, the microcontroller MCU 21 in the power supply component 200 of the VR device 400 is also used to communicate with the main control chip CPU 31 of the head display component 300 based on the power transmission protocol through the configuration channel CC pin 212.

[0049] The configuration channel CC pin 212 includes a CC1 pin and a CC2 pin. In the USB 3.0 standard protocol, the CC1 pin is the A5 pin of USB 3.0, and the CC2 pin is the B5 pin of USB 3.0.

[0050] In the embodiment of the present application, when the power supply component 200 is inserted into the head display component 300, the microcontroller MCU 21 of the power supply component 200 first supplies power to the electronic load of the head display component 300 through the general input / output GPIO pin 211, and when a short falling edge is detected on the voltage of the general input / output GPIO pin 211, the interrupt wake-up of the microcontroller MCU 21 is triggered. Then the microcontroller MCU 21 communicates with the main control chip CPU 31 of the head display component 300 based on the power transmission protocol through the configuration channel CC pin 212, so that through the communication interaction between the microcontroller MCU 21 and the main control chip CPU 31, the power supply component 200 obtains the power supply voltage required by the head display component 300 and the access status of the head display component 300, and outputs the required power supply voltage to the head display component 300, thereby improving the accuracy of power supply.

[0051] Fig.10 FIG. 1 shows a circuit diagram of another VR device provided in an embodiment of the present application in an implementation manner, see FIG. Fig.10 The microcontroller MCU 21 of the power supply component 200 in the VR device 400 may also include a B6 / B7 pin 213.

[0053] The serial communication protocol may include a Universal Asynchronous Receiver / Transmitter (UART) protocol and an Inter-Integrated Circuit (I2C) protocol.

[0054] In the embodiment of the present application, after the microcontroller MCU 21 of the power supply component 200 detects that the voltage of the general input / output GPIO pin 211 produces a short falling edge, triggering the interrupt wake-up of the microcontroller MCU 21, the microcontroller MCU 21 of the power supply component 200 communicates with the main control chip CPU of the head display component 300 through the B6 / B7 pin 213 based on the serial communication protocol, so that the main control chip CPU obtains relevant information of the power supply component 200, such as power information, or controls the status of the power supply component, such as powering on and off the power supply component.

[0055] Optional, such as Fig.10 As shown, the main control chip CPU 31 of the head display component 300 also includes a B12 pin, which is connected to the general input / output GPIO pin 211 of the microcontroller MCU 21 of the power supply component 200, so that when the power supply component 200 is inserted into the head display component 300, the microcontroller MCU 21 of the power supply component 200 pulls down the voltage of the general input / output GPIO pin 211, which is equivalent to pressing the power on button of the head display component 300 to start the head display component 300, so that the VR device 400 works normally.

[0056] In addition, when the power supply component 200 in the VR device 400 provided in the embodiment of the present application is unplugged from the head display component 300, the microcontroller MCU of the power supply component 200 detects that the voltage of the configuration channel CC pin has changed, so that the first power management chip PMIC 22 of the power supply component 200 disconnects the battery 23 from supplying power to the head display component 300, so that the power supply component 200 enters a low power consumption mode.

[0057] It should be noted that the microcontroller MCU and the first power management chip PMIC of the power component in the VR device provided in the embodiment of the present application are connected to the charging interface through corresponding pins (for example, USB PHY pins, CC pins) to charge the battery in the power component. The various pins of the power component (for example, general input / output GPIO pins, configuration channel CC pins, and B6 / B7 pins) are integrated through the Type-C male socket, and the various pins of the head display component are integrated through the Type-C female socket, so that the power component can be inserted into the head display component by inserting the Type-C male socket into the Type-C female socket.

[0058] Through the embodiments of the present application, when the VR device has no power button, the head-mounted display component can be automatically powered on by inserting the power component into the head-mounted display component, and the power component can be switched into a low-power consumption mode by unplugging the power component from the head-mounted display component, thereby reducing the power consumption of the power component when the head-mounted display component is idle and solving the unsafe problem of over-discharge of the battery in the power component.
