Thus, the charging interface can be better protected.

According to the application, the charging interface can be protected by arranging the protection sheet 6 beside the charging interface, namely, when the charging interface is not used, the protection sheet 6 slides towards the charging window 33 to completely cover the charging window 33, so that the charging interface is prevented from being damaged as much as possible, and the use safety of the patch board structure is further improved. Meanwhile, when the charging interface is required to be used, the protection sheet 6 is slid to be completely exposed out of the charging window 33 in the direction away from the charging window 33, so that the normal use of the charging interface is not affected, and the charging interface has the effects of convenience in use and simplicity in overall structure.
