[0003] The traditional method is to install a diode at the position of the charging interface, which can produce one-way conduction and reverse cut-off function, but the diode will produce voltage drop and power consumption, and the current will produce a 0.35V voltage drop, which will reduce the voltage of the mobile phone and VR glasses. Lower than 4.5V, resulting in failure to charge

The invention discloses a charging apparatus for VR eyeglasses and a mobile terminal. The charging apparatus comprises a mobile terminal USB interface, a VR eyeglass charge interface and an external power supply device. The mobile terminal USB interface supplies power to the VR eyeglasses through the external power supply device; or the mobile terminal USB interface is electrically connected with the VR eyeglass charge interface to enable the mobile terminal to supply power to the VR eyeglasses; an ID switching unit is electrically connected with a mobile terminal wiring port and a VR eyeglass end wiring port; and the ID switching unit sets external source voltages into mobile terminal charge voltages and VR eyeglass power supply voltages, charges the mobile terminal through the mobile terminal wiring port and charges the VR eyeglasses through the VR eyeglass end wiring port. According to the invention, the mobile terminal is prevented from charge failure due to too low voltages, caused by a voltage drop generated when currents flow through a diode due to high impedance of the diode, and a user can also charge the mobile terminal while playing games.
Description
technical field [0001] The invention relates to the field of VR glasses, in particular to a charging device for VR glasses and a mobile terminal. Background technique [0002] There is a USB charging interface on the outside of the VR glasses, which can realize the charging function when the voltage is too low. Generally, the mobile phone is connected to the VR glasses, and the mobile phone supplies power to the main board of the VR glasses through the USB interface. When the power of the mobile phone is insufficient, it can be connected to an external power source through the USB interface on the VR glasses, and the current enters through the USB interface to charge the mobile phone and power the VR glasses at the same time. [0003] The traditional method is to install a diode at the position of the charging interface, which can produce one-way conduction and reverse cut-off function, but the diode will produce voltage drop and power consumption, and the current will prod...
