Description

[Technical Field]

[0001] This utility model relates to the field of mobile battery technology, specifically to a mobile battery with a power cut-off function based on physical structure. [Background technology]

[0002] With the widespread use of portable electronic devices, mobile batteries have become an indispensable power supply device for people's daily work, life, and travel. Whether it is consumer electronic products such as smartphones and tablet PCs, smart wearable devices, or small office equipment, the driving range of these devices often does not meet the needs of long-term outdoor use or long-distance travel. Mobile batteries, with their portability and high-efficiency charging advantages, effectively solve this problem, and their market demand is continuously increasing.

[0003] However, existing mobile batteries have a clear problem with standby power consumption due to their technical design. Conventional mobile batteries often use electronic switches or logic control circuits to connect and disconnect between the battery and the motherboard. Therefore, even when no external devices are connected and the battery is in standby mode and no power supply is required, the motherboard remains in low-power operation mode, continuously consuming power from the battery. This standby power consumption not only shortens the standby time of the mobile battery, but also causes rapid power loss during long-term storage or carrying, resulting in insufficient power supply when in use. Furthermore, repeated low-power consumption over a long period of time accelerates the deterioration of the battery, shortening the battery's cycle life and increasing user costs.

[0004] Therefore, developing a mobile battery that can effectively cut off standby power consumption, achieve complete power cut-off between the battery and the motherboard through physical isolation means, and further extend standby time and service life is an important direction to meet the actual needs of users and make up for the shortcomings of existing technology.

[0024] 4, a first magnet 242 is provided at fixed end 24, and a second magnet 262 is provided at movable end 26, so that when metal plug 261 is inserted into electrical connection jack 241, first magnet 242 and second magnet 262 are attracted to each other.

[0025] 4, a linking hole 263 is formed in the movable end 26, and a stopper pin 281 is formed in the push button 28. The stopper pin 281 engages with and is inserted into the linking hole 263, causing the push button 28 and the movable end 26 to move synchronously.
