Title:
BATTERY PROTECTION ASSEMBLY, WIRELESS EARPHONE ASSEMBLY, ELECTRONIC DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/134448
Kind Code:
A1
Abstract:
The embodiment of the present application provides a battery protection assembly, which comprises a first battery protection circuit and a first switch unit, wherein a first power supply end and a first power grounding end are used for being electrically connected to the anode and cathode of a first battery in a one-to-one correspondence manner, a first logic control unit is electrically connected to the first switch unit so as to control the first switch unit to be turned on or turned off, and the first switch unit is used for controlling the first battery to supply power to a system circuit. When the first battery protection circuit identifies a shipping entry signal, the first battery protection circuit delays the eighth preset time period; the first battery protection circuit outputs a shipping feedback signal to the system circuit within the eighth preset time period, such that the system circuit is enabled to be shut down; the first battery protection circuit enters a shipping mode following the eighth preset time period, and the first switch unit is turned off in the shipping mode, such that the first battery stops supplying power to the system circuit. The embodiments of the present application further provide a wireless earphone assembly, an electronic device and a control method.
