However, it is very inconvenient for people to carry the mobile charger when they go out, and when the mobile charger is used, if the power of the mobile charger is insufficient, it cannot provide power for the smart mobile terminal. Based on this, people have developed a mobile power rental cabinet, including a charging base and a shared mobile power supply placed on the charging base. People can scan the code to rent the shared mobile power supply when they are in use, and scan the code to return the shared mobile power supply after use.

However, when judging whether the shared mobile power supply is detached from the charging base and whether it is reconnected to the charging base, the traditional mobile power supply rental cabinet generally installs a permanent magnet at one end of the electromagnet opposite to the internal Hall element. , or judged by the travel switch. When the permanent magnet element is close to the Hall element, the chip in the mobile power supply rental cabinet can sense the level change, so that it can know whether the shared mobile power supply is connected to the charging base or has left the charging base. However, the sensing distance of the permanent magnet element is fixed, so the maximum sensing distance cannot be adjusted. When the distance between the Hall element and the permanent magnet element becomes longer, the chip cannot sense the level change when the permanent magnet element is close to the Hall element.

Detailed ways

With the rise and promotion of smart mobile terminals, people increasingly rely on the work and operation of smart mobile terminals in work and life, and the battery capacity of smart mobile terminals is far from meeting people's needs. Therefore, there are many mobile chargers for smart mobile terminals on the market, which meet the needs of people who need to charge smart mobile terminals when they go out. However, it is very inconvenient for people to carry the mobile charger when they go out, and when the mobile charger is used, if the power of the mobile charger is insufficient, it cannot provide power for the smart mobile terminal. Based on this, people have developed a mobile power rental cabinet, including a charging base and a shared mobile power supply placed on the charging base. People can scan the code to rent the shared mobile power supply when they are in use, and scan the code to return the shared mobile power supply after use.

However, when judging whether the shared mobile power supply is detached from the charging base and whether it is reconnected to the charging base, the traditional mobile power supply rental cabinet generally installs a permanent magnet at one end of the electromagnet opposite to the internal Hall element. When the permanent magnet element is close to the Hall element, the chip in the mobile power supply rental cabinet can sense the level change, so that it can know whether the shared mobile power supply is connected to the charging base or has left the charging base. However, the sensing distance of the permanent magnet element is fixed, so the maximum sensing distance cannot be adjusted. When the distance between the Hall element and the permanent magnet element becomes longer, the chip cannot sense the level change when the permanent magnet element is close to the Hall element. Relative movement, that is, whether the shared power bank is connected to the charging base or left the charging base.

Therefore, in the traditional solution, the device for detecting whether the shared mobile power supply is connected to the charging base has the problem that it cannot accurately record whether there is relative movement between the shared mobile power supply and the charging base. Based on this, the present application provides a mobile power charging base 10 and a charging system 30 thereof.
