  • Publication number: 20180301944
    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.

  • Patent number: 10078929
    Abstract: A wireless transmission system used for a self-locking lock box has a first transmission unit received in a first insert hole of a door frame, and a self-locking lock box secured at a door plank. The self-locking lock box is provided therein with a square bolt able to eject out of the lock box, and the square bolt is connected with a control pin and has its front end fixed with a second transmission unit. By so designing, when a user closes the door plank, the control pin will be pressed by the door frame and release the square bolt to make the square bolt eject out of the self-locking lock box and get into the first insert hole of the door frame, thus enabling the first transmission unit to approach the second transmission unit for elevating transmission efficiency.
