Abstract

Embodiments of the present invention provide a smart wearable device and a power supply method thereof, which relate to the field of electronic technology, can prolong the battery life, and enable the smart wearable device to complete main functions within a certain period of time when the battery cannot output current. Function. The smart wearable device includes: a control unit, a battery power supply unit, a self-power supply unit, a basic function unit and a non-basic function unit; the control unit is used to detect the output voltage of the battery power supply unit when the smart wearable device is worn; when the output voltage is less than When the first voltage threshold value is reached, control the non-basic functional units to stop working, and control the self-power supply unit to supply power to the basic functional units; when the output voltage is greater than or equal to the first voltage threshold value, control the self-powered unit and the battery power supply unit to be basic Functional units and non-basic functional units provide power; self-powered units continue to generate electricity when the smart wearable device is worn. The smart wearable device is applied in the field of consumer electronics.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a smart wearable device and a power supply method thereof. Background technique [0002] With the rapid development of smart sensor technology, the demand for smart wearable devices (including smart bracelets, smart watches, etc.) has also begun to grow explosively. Smart wearable devices generally have main functions, such as the motion detection function of smart sports bracelets, the health detection functions of smart health monitoring bracelets, etc. Smart wearable devices also have some other functions, such as the global positioning system (English: global positioning system, abbreviation : GPS), Bluetooth calls, music playback and other functions. [0003] At present, limited by the size of the smart wearable device, the capacity of the battery of the smart wearable device is generally small, for example, the capacity of a lithium-ion battery configured in a smart bracelet or ...
