In one embodiment, referring to fig. 5 to 7, the main control board 11 is further configured to control the second coil 14 to be powered off when it is determined that the magnetic needle 122 is in poor electrical contact with the sensing element 24. Like this, can play secondary protection shared treasured that charges 20, avoid shared treasured that charges 20 not borrowed or embezzled in violation of rules and regulations.

Specifically, referring to fig. 5 to 7, the main control board 11 is further configured to send a signal that the charging pogo pin 17 is in contact with the shared charging pad to a cloud server when it is determined that the charging pogo pin 17 is in electrical contact with the shared charging pad 20. Thus, when the charging pin 17 is electrically contacted with the shared power bank 20, on one hand, it indicates that the shared power bank 20 has been returned to the charging dock 10, and on the other hand, the charging dock 10 can supplement the returned shared power bank 20 with electric energy.

In an embodiment, referring to fig. 5 to 7, when the shared charger bank 20 is in a specific return operation, if the cloud server determines that the shared charger bank 20 is electrically contacted with the charging pin 17 of the charging dock 10 and the magnetic pin 122 of the charging dock 10 is inserted into the buckle hole 22 of the shared charger bank 20, it is determined that the shared charger bank 20 is normally returned and the charge is settled; if the cloud server determines that the shared charger baby 20 is in electrical contact with the charging pin 17 of the charging stand 10, but does not receive a signal that the magnetic pin 122 of the charging stand 10 is inserted into the buckle hole 22 of the shared charger baby 20, the cloud server prompts the user that the shared charger baby 20 is returned illegally, at this time, the charging fee is not settled, and meanwhile, the user is given a bad credit record, so that the shared charger baby 20 can be prevented from being stolen for free.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
