Abstract: A wireless power supply device and method applied to an electronic lock is implemented between a power supply unit and a power receiving unit. The power supply unit is connected to an external power source and has a first radio frequency coil and a first wireless communication module. The power receiving unit is connected to an electronic lock and has a second radio frequency coil and a second wireless communication module. When the power supply unit wirelessly transmits the power provided by the external power source to the power receiving unit, the power receiving unit and the power supply unit perform a handshaking process to confirm whether they are paired objects, if yes, the power is allowed to be transmitted to the electronic lock, so that the security of wireless power supply can be improved.

Abstract: A non-contact transmission device for an electronic lock includes a housing. The housing has an accommodation trough to accommodate a retainer in a slidable manner. The retainer is provided with an RFID coil. An inner side of the housing is formed with a positioning trough. When the retainer is slid in the accommodation trough, the RFID coil is positioned in the positioning trough, such that the RFID coil is closer to the outer edge of the housing without lowering the strength of the housing. When two non-contact transmission devices are mounted to a door frame and a door panel respectively, the distance between the RFID coils of the two non-contact transmission devices can be shortened to improve the transmission efficiency between the RFID coils.

The groove penetrates downward through the first housing of the receptacle and can accept a first locking piece. The first locking piece has a U-shaped body received in the groove, which extends to form welding portions, and the welding portions project out of the first housing. An inserting groove is opened in the end of the plug. The inserting groove can accept a second locking piece. A straight arm of the second locking piece projects out of the second housing of the plug. The board to board connector can be welded in PCBs by the first and second locking pieces.
