Title:
HUMAN BODY DISTANCE DETECTION MODULE OF ELECTRONIC DEVICE, ELECTRONIC DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/072982
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of wireless communication, and provided therein are a human body distance detection module of an electronic device, an electronic device and a control method therefor. The human body distance detection module comprises a first metal sheet, a capacitance sensor, and a second metal sheet. When a human body approaches or moves away from any side of the first metal sheet, the capacitance to ground of the first metal sheet will be affected. Since the second metal sheet is not parallel to the first metal sheet, at least a part of the second metal sheet is arranged opposite to the first metal sheet, and the two are insulated from one another so as to be able to couple to one another, thus, when the human body approaches an electronic device in a direction approximately parallel to the first metal sheet, the capacitance to ground of the first metal sheet may change significantly, and a change in the distance between the human body and the electronic device may still be reflected by means of a change in the capacitance to ground.
