[0055] As Figure 1 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.

[0056] Further, as Figure 1 shown, a 5G device externally connected to a VR headset according to an embodiment of the present invention further includes: a charger, and the charger is connected to the charging port TYPE-C_3.

[0057] Further, as Figure 1 shown, a 5G device externally connected to a VR headset according to an embodiment of the present invention further includes: a NANO SIM card, and the NANO SIM card is connected to the 5G module.

[0058] Further, as Figure 1 shown, a 5G device externally connected to a VR headset according to an embodiment of the present invention further includes: a fifth diode, and the fifth diode connects the digital headphone interface TYPE-C_2 and the electronic switch 1.

[0059] As Figures 1 to 2As shown, when the toggle switch conducts between pin 1 and pin 2, CC1 of the docking port TYPE-C_4 of the VR headset is pulled low to ground by the first resistor R1, putting the VR headset in Host mode. The VR headset acts as a host to supply power and transfer data outward, outputting VR_USB_OTG_Power_5V to power and transfer data to the hub chip USB3.0 HUB, the 5G module, and the digital headphone interface TYPE-C_2.

[0060] As Figures 1 to 2 shown, when the toggle switch conducts between pin 2 and pin 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 floating, the VR headset can be changed to Device mode, and it 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. The 5G module and the digital headphone interface TYPE-C_2 are both connected to the hub chip USB3.0 HUB, so that the 5G module and the digital headphone interface TYPE-C_2 can work simultaneously. 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.

[0061] As Figure 1 、 3 shown, the USB2.0 data signals VR_USB_DP / VR_USB_DM output by the first interface TYPE-C_1 are time-division multiplexed through the switching switch chip U1. The switching switch chip U1 uses WAS7227Q of Well Semiconductor. When the charger is not inserted into the charging port TYPE-C_3, there is no voltage on pin 10 of the switching switch chip U1, which is pulled low by the fourteenth resistor R33. Pins 1 and 5 of the switching switch chip U1 are conducted, and pins 2 and 4 are conducted. At this time, the USB2.0 signal goes to the hub chip USB3.0 HUB. When the charger is inserted into the charging port TYPE-C_3, there is a 5V voltage VCHG_5V on pin 10 of the switching switch chip U1, the SEL of the switching switch chip U1 is pulled high, pins 1 and 7 of the switching switch chip U1 are conducted, and pins 2 and 6 are conducted. At this time, the USB2.0 signal goes to the charger for charging protocol communication. 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 switch chip U1 through the third diode D10 and the fourth diode D11.

[0062] AsFigure 1 , 4 As shown in 4 , the 5V voltage VR_USB_OTG_POWER_5V input by the first interface TYPE-C_1 powers the hub chip USB3.0 HUB, the 5G module, and the Type-C digital headset through the electronic switch 1. The current-limiting switch U2 uses WS4603E-5 / TR of Well Semiconductor. When the 2nd and 3rd pins of the toggle switch are conducted, the 4th pin of the current-limiting switch U2 is pulled low, and the current-limiting switch U2 is turned off. The power supply interfaces of the hub chip USB3.0 HUB, the 5G module, and the digital headset are disconnected and do not work. At this time, the VR headset device can be charged.

[0063] As Figure 1 , 5 shown in Figure 1 , the electronic switch 2 is composed of the first MOS transistor Q1, the second MOS transistor Q2, and a triode Q3. When the 2nd and 3rd pins of the toggle switch are conducted, 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 conducted, and at the same time, the first MOS transistor Q1 and the second MOS transistor Q2 are also conducted. The TYPE-C_3_5V voltage output by the charger through the charging port TYPE-C_3 charges the VR headset. When the 1st and 2nd pins of the toggle switch are conducted, at this time, the triode Q3 is turned off, and then the first MOS transistor Q1 and the second MOS transistor Q2 are also turned off, and the VR headset cannot be charged.

[0064] Above, with reference to Figures 1 to 5 A 5G device externally connected to a VR headset according to an embodiment of the present invention is described. By externally connecting a 5G device using the Type-C interface of the VR headset, the VR headset can access the Internet through the external 5G device. At the same time, the device can also undertake the function of audio output and charging the VR headset, thereby enhancing the flexibility and convenience of using the VR headset in an environment without Wi-Fi or with poor signal.
