[0077] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0078] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0079] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0080] With the rapid development of VR technology and applications, VR devices (such as VR smart glasses) have been applied to industrial manufacturing, information technology, medical care, petrochemicals, electricity, railways, education and scientific research and other industries.

[0081] VR smart glasses are head-mounted electronic devices, which include a VR controller and a VR display device. Users can use the VR controller to interact with the VR space in the virtual reality scene displayed by the VR display device. Currently, the VR controller can be powered by a battery. After the battery is inserted, the VR controller can automatically turn on and automatically enter a dormant state after a period of inactivity or disconnection from the VR display device.

[0082] When the VR controller enters sleep mode, unnecessary energy consumption will be generated. The user needs to manually remove the battery to force power off to avoid this energy consumption. This is inconvenient for users and results in a poor user experience. However, if the battery is not removed, the battery life will be affected.

[0083] Therefore, the present application provides a VR handle, which controls the power supply voltage of the VR handle when it enters the working state and the sleep state, so that the VR handle runs with low power consumption when it enters the sleep state. Specifically, the power supply of the sensor system in the VR handle can be disconnected, and then the power supply voltage of the control component of the VR handle is lower than the voltage corresponding to the working state, thereby reducing power consumption and improving battery life.

[0084] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other or exist independently. The same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0085] Figure 1 A schematic diagram of a VR system according to an embodiment of the present application is shown in FIG. Figure 1 As shown, the VR system includes a VR handle 10 and a VR display device 20. Figure 1 As shown, a plurality of LEDs are provided on the VR handle 10. The camera 202 on the VR display device 20 collects an image formed when the LED on the VR handle 10 is lit, and then the image is analyzed by a processor (not shown) on the VR display device 20 to realize the positioning and tracking of the VR handle 10, and then realize the positioning and tracking of the moving target corresponding to the VR handle 10 within the virtual space, so as to realize interaction.

[0086] In a possible implementation, the VR handle 10 may also be provided with buttons (not shown in the figure), which include physical buttons and / or touch buttons. The user can operate the VR display device 20 through the buttons on the VR handle 10.

[0090] The camera 202 is provided on the VR display device 20, and is used to obtain image data formed when the LED on the handle 10 is lit. Exemplarily, the camera 202 may be a binocular camera, and the model of the binocular camera may be selected according to actual needs, and this application does not limit it.

[0096] The control component 102 is connected to the power supply system 103, and the control component 102 is also configured as follows:

[0097] Detect whether the operating status of the VR controller has changed;

[0098] If yes, then the changed operating state of the VR handle 10 is determined, and the operating state is a sleep state or a working state.

[0100] Exemplarily, the control component 102 may detect whether the operating state of the VR handle 10 has changed in the following manner:

[0101] Mode 1: When the VR handle 10 has no operation within a first preset time period, that is, when the user does not move the VR handle 10 for a long time, it can be determined that the operating state of the VR handle has changed, that is, from a working state to a sleeping state.

[0102] Mode 2: When the VR handle 10 is disconnected from the VR display device 20, it can be determined that the operating state of the VR handle has changed, that is, from the working state to the sleeping state.

[0103] Mode 3: When the VR handle 10 is disconnected from the VR display device 20 for a second preset time period, it can be determined that the operating state of the VR handle has changed, that is, changed from a working state to a sleeping state.

[0104] Mode 4: After entering the sleep state, when the VR handle 10 is moved, it can be determined that the operating state of the VR handle has changed, that is, changed from the sleep state to the working state.

[0105] Mode 5, when the VR handle 10 is connected to the VR display device, it can be determined that the operating state of the VR handle has changed, that is, changed from a sleep state to a working state.

[0106] It can be understood that the way in which the control component 102 detects whether the operating state of the VR handle 10 has changed is not limited to the above-mentioned way, and can also be detected by other ways, which is not limited in this application.

If the operating state is the dormant state, the power supply system 103 is controlled to disconnect the power supply voltage of the sensor system 101 through the power load switch 104, and the power supply system 103 is controlled to provide a first voltage to the control component 102, and the first voltage is less than the working voltage of the control component when the VR handle 10 is in the working state, so that the VR handle 10 runs at low power consumption when entering the dormant state, thereby achieving the purpose of saving power consumption and improving the battery life.

[0109] The power supply system 103 provided in the embodiment of the present application is described in detail below.

[0110] Figure 4 A structural diagram of another VR handle provided in an embodiment of the present application is shown in FIG.

[0113] Exemplarily, the power supply 31 may be a dry cell battery, for example, a 1.5V dry cell battery, and the output voltage of the power supply 31 may be 1.5V.

[0114] Exemplarily, the voltage conversion circuit 32 can provide different operating voltages for the sensor system 101 and the control component 102 according to the output voltage of the power supply 31 when the VR handle 10 is in different working states. For details, please refer to the following embodiments.

[0115] In a possible implementation, the control component 102 is configured to:

[0116] If the operation state is the working state, the power supply system 103 is controlled to provide a second voltage to the sensor system 101 through the power load switch 104, and the power supply system 103 is controlled to provide a second voltage to the control component 102, and the second voltage is greater than the first voltage.

[0118] Figure 5 A schematic diagram of the circuit structure of a voltage conversion circuit 32 provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the voltage conversion circuit 32 includes a boost chip 311, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a first capacitor C1, a second capacitor C2, a third capacitor C3, a fourth capacitor C4, a fifth capacitor C5 and a first inductor L1.

[0119] The first end of the first resistor R1 is connected to the first pin (EN, i.e., the enable pin) of the boost chip 311, and the second end of the first resistor R1 is connected to the power supply 31 through a first connection line. The first end of the fourth capacitor C4 and the fifth capacitor C5 connected in parallel is connected to the second pin (IN, i.e., the input pin) of the boost chip 311 through a second connection line, the second end of the fourth capacitor C4 and the fifth capacitor C5 connected in parallel is grounded, and the second connection line is connected to the first connection line through a third connection line.

[0120] The first end of the first inductor L1 is connected to the third pin of the boost chip 311 (LX in the figure, i.e., the power external inductor terminal), and the second end of the first inductor L1 is connected to the power pin of the control component 102 (i.e., Figure 3 VCC in) is connected through a fourth connecting line.

[0121] The third capacitor C3 is connected in parallel with the second resistor R2, the first end of the second resistor R2 is connected to the second end of the first inductor L1, the second end of the second resistor R2 is connected to the first end of the third resistor R3 through the fifth connecting line, the second end of the third resistor R3 is connected to the first control pin of the control component 102, the fourth pin of the boost chip 311 is connected to the fifth connecting line, the first end of the fourth resistor R4 is connected to the fifth connecting line, and the second end of the fourth resistor R4 is grounded.

[0122] A first end of the first capacitor C1 is connected to the fourth connection line, a second end of the first capacitor C1 is grounded, a first end of the second capacitor C2 is connected to the fourth connection line, and a second end of the second capacitor C2 is grounded.

[0123] It should be noted that in Figure 5 and Figure 6 In the figure, 1 represents a first end, and 2 represents a second end. For example, 1 of the first capacitor C1 represents a first end, and 2 of the first capacitor C1 represents a second end.

[0124] Based on the above voltage conversion circuit 32, the relationship between the output voltage of the circuit and each resistor is as follows:

[0125]

[0126] Among them, V FB is the feedback voltage of the boost chip 311, R2 is the resistance value of the second resistor R2, R3 is the resistance value of the third resistor R3, R4 is the resistance value of the fourth resistor R4, V SYS_SLEEP The pin voltage of the first control pin of the control component 102 can have three states, namely low level, high level and high resistance state, among which the high resistance state can be understood as the first control pin is disconnected from the third resistor, that is, the first control pin is in the disconnected state, at this time, the third resistor is disconnected.

[0127] Exemplarily, if the output voltage of the power supply is 1.5V, 3.3V and 1.8V can be obtained through the voltage conversion circuit 32, wherein 3.3V can be the second voltage and 1.8V can be the first voltage.

[0128] Based on the above relationship (1), the control component 102 controls the voltage conversion circuit 32 to output the first voltage and the second voltage in the following ways, but not limited to:

[0129] Method A

[0130] If the running state is the working state, the control component 102 can control the first control pin to be at a low level, V SYS_SLEEP =0, at this time VCC is the second voltage.

[0131] If the operating state is the sleep state, the control component 102 can control the first control pin to be high level, V SYS_SLEEP =VCC, at this time VCC is the first voltage.

[0132] That is to say, in mode A, when the first control pin is controlled to be at a low level, the output voltage of the voltage conversion circuit 32 is the second voltage, and when the first control pin is controlled to be at a high level, the output voltage of the voltage conversion circuit 32 is the first voltage.

[0133] Method B

[0134] If the running state is the working state, the control component 102 can control the first control pin to be at a low level, V SYS_SLEEP =0, at this time VCC is the second voltage.

[0135] If the operating state is the sleep state, the control component 102 can control the first control pin to be in a high impedance state, and VCC is a first voltage.

[0136] That is to say, in mode B, when the first control pin is controlled to be at a low level, the output voltage of the voltage conversion circuit 32 is the second voltage, and when the first control pin is controlled to be in a high impedance state, the output voltage of the voltage conversion circuit 32 is the first voltage.

[0137] Method C

[0138] If the operation state is the working state, the control component 102 can control the first control pin to be in a high impedance state, and VCC is the second voltage.

[0139] If the operating state is the sleep state, the control component 102 can control the first control pin to be at a high level, V SYS_SLEEP =VCC, at this time VCC is the first voltage.

[0140] That is to say, in mode C, when the first control pin is controlled to be in a high impedance state, the output voltage of the voltage conversion circuit 32 is the second voltage, and when the first control pin is controlled to be in a high level, the output voltage of the voltage conversion circuit 32 is the first voltage.

[0141] For the above method, the control component 102 can realize the control of the voltage conversion circuit 32 in any way. After determining the control level of the target method, the proportional relationship between the second resistor R2, the third resistor R3 and the fourth resistor R4 can be determined, so that the voltage output control of the voltage conversion circuit 32 can be realized.

[0142] In a possible implementation, the power load switch 104 may be a MOS tube (positive channel Metal Oxide Semiconductor, PMOS) with an n-type substrate and a p-channel, which transports current by the flow of holes. MOS is a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), which can be referred to as MOS.

[0143] Figure 6 A schematic diagram of the structure of a power load switch 104 provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, the gate of the power load switch 104 is connected to the second control pin of the control component 102 , the source of the power load switch 104 is connected to the power pin of the control component 102 , and the drain of the power load switch 104 is connected to the sensor system 101 .

[0144] Specifically, Figure 6 As shown, the drain of the power load switch 104 is connected to the sixth connection line, two ends of the sixth connection line are connected to the sixth capacitor C6 and the sensor system 101, and the other end of the sixth capacitor C6 is grounded.

[0145] The control component 102 controls whether the power supply system 103 supplies power to the sensor system 101 through the power load switch 104, for example, may be:

[0146] If the running state is the working state, the control component 102 can control the power supply system 103 to disconnect the power supply voltage to the sensor system 101 when the second control pin is at a low level, that is, when the second control pin is at a low level, the sensor system 101 is powered off.

[0147] If the running state is the sleep state, the control component 102 can control the second control pin to be high level, and control the power supply system 103 to provide the second voltage to the sensor system 101, that is, when the second control pin is high level, the second voltage is provided to the sensor system 101.

[0148] It can be seen that the way in which the control component 102 controls whether the power supply system 103 supplies power to the sensor system 101 through the power load switch 104 is the same as the control method of the above-mentioned method A. If the control component 102 controls the voltage conversion circuit 32 to output the first voltage and the second voltage in the above-mentioned method A, the first control pin and the second control pin can be the same pin, that is, the control component 102 can be connected to the third resistor R3 and the gate of the power load switch 104 respectively through one control pin.

[0149] Correspondingly, if the control component 102 controls the voltage conversion circuit 32 to output the first voltage and the second voltage in the above-mentioned method B or method C, then the control component 102 needs to be connected to the third resistor R3 and the gate of the power load switch 104 respectively through two control pins.

[0150] Exemplarily, the first control pin and the second control pin may be general purpose input output (GPIO) pins.

[0151] In this embodiment, the power load switch 104 may be a PMOS, which has a fast response speed and a low on-resistance, so that the power supply control effect of the sensor system 101 is better.

[0152] In the related art, the control component 102 can be connected to the sensor system 101 through an interface such as an Inter-Integrated Circuit (I2C) or a Serial Peripheral Interface (SPI). The control component 102 can control the sensor system 101 through I2C and SPI. For example, the control component 102 can be connected to the touch sensor and the linear motor in the sensor system 101 through the I2C interface, and the control component 102 can be connected to the gyroscope sensor in the sensor system 101 through SPI. (However, I2C and SPI cannot control the high and low levels of their outputs.)

[0153] If the operating state is the sleep state, the control component 102 controls the sensor system 101 to cut off the power through the power load switch 104, then the sensor system 101 may leak electricity and the registers in the sensor may become abnormal. Therefore, before controlling the sensor system 101 to cut off the power, the sensor system 101 can be controlled to enter the sleep state.

[0154] In a possible implementation, the control component 102 is connected to the sensor system 101 via a preset interface, and the preset interface is used to control the state of the sensor system 101, which is a working state or a dormant state.

[0155] When the operation state of the VR handle 10 is the sleep state, the control component 102 can send a first control signal to the sensor system 101 to control the state of the sensor system 101 to be the sleep state. It can be understood that at this time, the I2C and SPI connections between the control component 102 and the sensor system 101 are disconnected.

[0156] When the VR handle 10 is in the working state, the control component 102 may send a second control signal to the sensor system 101 to control the sensor system 101 to be in the working state. It can be understood that at this time, the I2C and SPI connections between the control component 102 and the sensor system 101 are restored.

[0157] For example, Figure 4 As shown, the preset interface may be a GPIO, the first control signal may be a low level signal of the GPIO, and the second control signal may be a high level signal of the GPIO.

[0158] In a possible implementation, if the operation state of the VR handle 10 is the dormant state, the control component 102 sends a first control signal to the sensor system 101 through a preset interface before controlling the power supply system 103 to disconnect the power supply voltage of the sensor system 101, so as to make the sensor system 101 enter the dormant state. That is, before power is cut off, the sensor system 101 is controlled to enter the dormant state, which can prevent the sensor system 101 from leaking electricity, control the power consumption to the minimum, and avoid abnormalities in the registers in the sensor.

[0159] In a possible implementation, if the operating state of the VR handle 10 is the working state, the control component 102 controls the power supply system 103 to provide the second voltage to the sensor system 101 after the control component 102 provides the second voltage for a preset period of time.

[0160] It can be understood that when the VR handle 10 is in a sleep state, the voltage conversion circuit 32 provides a first voltage to the control component 102. After the operating state of the VR handle 10 changes, that is, after it is converted to a working state, the voltage conversion circuit 32 provides a second voltage to the control component 102. The process of the voltage conversion circuit 32 changing from the first voltage to the second voltage requires a certain period of time before providing a stable second voltage to the control component 102. The above-mentioned preset time period may be greater than or equal to this time period.

[0161] That is, after the control component 102 is powered for a preset period of time, that is, after the second voltage is stabilized, the control component 102 can control the second control pin to be high level to control the power load switch 104 to open, so that the power supply system 103 provides the second voltage to the sensor system 101. At the same time, the control component 102 can restore the I2C and SPI connections between the control component 102 and the sensor system 101 to ensure that the sensor function returns to normal.

[0162] Below, based on the above-mentioned VR handle, the control method of the VR handle provided in the embodiment of the present application is described.

[0163] Figure 7 A flowchart of a method for controlling a VR handle provided in an embodiment of the present application is provided. The method can be executed by the control component of the VR handle, such as Figure 7 As shown, the method may include the following steps.

[0171] In this embodiment, by detecting whether the operating state of the VR handle has changed, if so, the operating state of the VR handle after the change is determined, and the operating state is a dormant state or a working state. If the operating state is the dormant state, the power supply system is controlled to disconnect the power supply voltage of the sensor system through the power load switch, and the power supply system is controlled to provide a first voltage to the control component, and the first voltage is less than the working voltage of the control component when the VR handle is in the working state. If the operating state is the working state, the power supply system is controlled to provide a second voltage to the control component, and the power supply system is controlled to provide a second voltage to the sensor system through the power load switch, so that the VR handle runs at low power consumption when entering the dormant state, thereby achieving the purpose of saving power consumption and improving the battery life.
