The MCU is also provided with a charging chip to become a booster circuit, and a 5V power supply is provided for the external AR glasses; the MCU can also read the residual capacity information of the CW2015 through the I2C, and the LED is controlled to indicate the residual capacity according to the residual capacity information.

The battery outputs a system main Power Supply from the VSYS through the charging chip, and the VSYS supplies Power to the MCU, the ASIC and the CW2015 after being converted by the Power Supply module Power Supply.

The HDMI of the screen projection adapting device can be used for connecting a Lightning-to-HDMI converter (converter for short), so that an HDMI video signal output by the converter can be converted into a DP video signal and output to a target device based on a Type-c interface through the Type-c interface, power can be supplied to the target device without a power supply, and the problems that the converter cannot output the video signal to the target device based on the Type-c interface and cannot provide enough power for driving the target device without the power supply and the like are solved.

In addition, the receiving groove of the screen projection adapting device can accommodate the converter, so that the converter and the screen projection adapting device can be integrally unified in appearance, and user experience is improved. The slope area of one end of the receiving groove can be conveniently pushed out of the converter when the converter and the data wire are disconnected, and the influence on the stability and the service life of the converter caused by the fact that the converter and the data wire are disconnected by pulling the converter is avoided. The converter can be connected with the screen projection adapting device more stably through the receiving groove, a structure matched with the shape of the converter is formed on two side walls of the receiving groove and the groove bottom, a stopping part is formed in the vertical direction of the groove bottom, the converter cannot shake in the directions vertical to the groove bottom and the two side walls and only can move relatively along the plugging and unplugging direction of the interface under the condition that the converter occupies a small space after being connected with the converter, and therefore after the converter is connected with the converter, the converter is fixed in the receiving groove, the connection stability of the converter and the receiving groove is guaranteed, and signal transmission is facilitated.
