[0027] like Figure 1 As shown, the charging port TYPE-C_3 is connected to the USB switch and the electronic switch 2; the hub chip USB3.0 HUB is connected to the electronic switch 1, the first interface TYPE-C_1, and the USB switch; the 5G module is connected to the hub chip USB3.0 HUB and the electronic switch 1; the digital headphone interface TYPE-C_2 is connected to the hub chip USB3.0 HUB and the electronic switch 1.

[0028] Further, if Figure 1 As shown, a 5G system externally connected to a VR head display according to an embodiment of the present invention further includes: a charger, and the charger is connected to the charging port TYPE-C_3.

[0029] Further, if Figure 1 As shown, a 5G system externally connected to a VR head display according to an embodiment of the present invention further includes: a NANO SIM card, the NANO SIM card is connected to the 5G module, Further, if Figure 1 As shown, a 5G system externally connected to a VR head display according to an embodiment of the present invention further includes: a fifth diode, which connects the digital headphone interface TYPE-C_2 and the electronic switch 1.

[0030] like Figure 1~2As shown, when the toggle switch is turned on at pins 1 and 2, CC1 of the docking port TYPE-C_4 of the VR headset is pulled down to ground by the first resistor R1, so that the VR headset is in Host mode. The VR headset acts as a host to provide power and data transmission, and outputs VR_USB_OTG_Power_5V to provide power and data transmission for the hub chip USB3.0 HUB, 5G module and digital headphone interface TYPE-C_2.

[0031] like Figure 1~2 As shown, when the toggle switch is turned on at pins 2 and 3, electronic switch 1 is turned off and electronic switch 2 is turned on. At this time, since CC1 of the docking port TYPE-C_4 of the VR headset is suspended, the VR headset can be changed to device mode and can be charged through the charging port TYPE-C_3. The VR headset data is connected to a hub chip USB3.0 HUB through the USB3.0 and USB2.0 interfaces on the docking port TYPE-C_4 and the first interface TYPE-C_1, and the 5G module and the digital headphone interface TYPE-C_2 are connected to the hub chip USB3.0 HUB at the same time, so that the 5G module and the digital headphone interface TYPE-C_2 can work at the same time. The USB2.0 signal line of the charging port TYPE-C_3 and the hub chip USB3.0 HUB is time-division multiplexed to the first interface TYPE-C_1 through a USB switch.

[0032] like Figure 1 , 3 As shown, the USB2.0 data signal VR_USB_DP / VR_USB_DM output by the first interface TYPE-C_1 is time-division multiplexed through the switching chip U1. The switching chip U1 uses the WAS7227Q of Will Semiconductor. When the charging port TYPE-C_3 is not inserted into the charger, the 10th pin of the switching chip U1 has no voltage and is pulled down by the fourteenth resistor R33. The 1st and 5th pins of the switching chip U1 are turned on, and the 2nd and 4th pins are turned on. At this time, the USB2.0 signal goes to the hub chip USB3.0 HUB. When the charging port TYPE-C_3 is inserted into the charger, the 10th pin VCHG_5V of the switching chip U1 has a 5V voltage, the SEL of the switching chip U1 is pulled high, the 1st and 7th pins of the switching chip U1 are turned on, and the 2nd and 6th pins are turned on. At this time, the USB2.0 signal goes to the charger to communicate the charging protocol. The 5V voltage TYPE-C_3_5V input by the charger through the charging port TYPE-C_3 and the 5V voltage VR_USB_OTG_POWER_5V input by the VR headset through the first interface TYPE-C_1 supply power to the switching chip U1 through the third diode D10 and the fourth diode D11.

[0033] like Figure 1 , 4 As shown, the 5V voltage VR_USB_OTG_POWER_5V input by the first interface TYPE-C_1 powers the hub chip USB3.0 HUB, 5G module and Type-C digital headset through the electronic switch 1. The current limiting switch U2 uses WS4603E-5 / TR of Will Semiconductor. When the 2nd and 3rd pins of the toggle switch are turned on, the 4th pin of the current limiting switch U2 is pulled low, and the current limiting switch U2 is turned off. The hub chip USB3.0 HUB, 5G module and digital headset power supply interface are disconnected and do not work. At this time, the VR head display device can be charged.

[0034] like Figure 1 , 5 As shown, the electronic switch 2 is composed of a first MOS tube Q1, a second MOS tube Q2 and a triode Q3. When the 2nd and 3rd pins of the toggle switch are turned on, the eighth resistor R3 and the triode Q3 are connected to the ground of the 2nd pin of the toggle switch through POWER_EN. At this time, the triode Q3 is turned on, and the first MOS tube Q1 and the second MOS tube Q2 are also turned on. The charger charges the VR head display through the TYPE-C_3_5V voltage output by the charging port TYPE-C_3. When the 1st and 2nd pins of the toggle switch are turned on, the triode Q3 is turned off, and then the first MOS tube Q1 and the second MOS tube Q2 are also turned off, and the VR head display cannot be charged.

[0035] Above, refer to Figures 1 to 5 A 5G system externally connected to a VR headset is described according to an embodiment of the present invention. By using the Type-C interface of the VR headset to connect a 5G device, the VR headset can access the Internet through the external 5G device. At the same time, the device can also assume the functions of audio output and charging the VR headset, thereby enhancing the flexibility and convenience of using the VR headset in environments without Wi-Fi or with poor signals.
