When the detection module 210 detects that the distance between the glasses and the human body is greater than or equal to the preset threshold, the glasses can be charged with the second power. When charging, the second power is greater than the first power. Of course, in practical applications, the charging power can also be divided into more types, and the embodiments of the present disclosure are not limited thereto.

The capacitance values of the two capacitor plates are given by the following formula:

d is the distance between the two plates, S is the facing area of the two capacitor plates, and k is the electrostatic constant. According to the capacitance formula, it can be seen that when d becomes smaller, the capacitance value C becomes larger; when d becomes larger, the capacitance value C becomes larger, so it can be Detects the distance between the human body and the electronic device through the conductor part on the electronic device.

On this basis, step S530 can be implemented in the following ways: detect the distance between the glasses and the human body; send an enable signal to the charging base according to the distance between the glasses and the human body, and use the enable signal to control the wireless charging base to transmit an air-to-air charging power signal. and control the power of the power signal.

When the power of the battery 130 is lower than the preset threshold, the detection module 210 starts to work.

In step S550 , the air charging antenna module 140 can be used to receive the air charging source signal, and the air charging power signal is used to provide power to the battery 130 .

When the charging base receives the enable signal, it emits an electromagnetic signal (air-to-air charging source signal) according to the enable signal. The air charging antenna module 140 in the glasses receives electromagnetic signals, converts the electromagnetic signals into electrical signals, and charges the battery 130 .

The air-to-air charging method for glasses provided by the embodiment of the present disclosure detects the remaining power of the battery 130 in the glasses; when the remaining power is less than a preset threshold, an enabling signal is sent to the charging base; and the air-to-air charging antenna module 140 is used to receive the air-to-air charging. The air charging source signal and the air charging power signal are used to provide power to the battery 130, enabling long-distance wireless charging of the battery 130 when the power of the glasses is less than the preset threshold, so that the glasses using the small-capacity battery 130 can be used longer.

The conversion circuit is used to connect to a power source and convert the power signal into an AC signal of a preset frequency. The transmitting antenna is connected to the conversion circuit. The transmitting circuit receives the AC signal output by the conversion circuit and emits electromagnetic signals through the excitation of the AC signal.

In the embodiment of the present disclosure, the glasses 100 and the charging base 200 can be wirelessly charged over a long distance. During long-distance wireless charging, the glasses 100 and the charging base 200 need to be positioned. On the one hand, the distance between the glasses 100 and the charging base 200 is determined. On the other hand, the orientation of the glasses 100 relative to the charging base 200 is determined. For example, the positioning of glasses and charging base can be achieved through UWB positioning.
