Abstract: A control device of electronic lock is provided for electrically connecting with a lock device of the electronic lock, so as to be adapted for controlling the operation of the lock device. The control device comprises a base plate, a circuit board, a plurality of illuminants, a plurality of communication resilience members, a lid locked on the base plate, an alignment plate, and a touch panel. The illuminants are arranged corresponding to the communication resilience members respectively. The touch panel is electrically connected with the communication resilience members. When the touch panel is touched, the communication resilience member corresponding to the touched position is electrically communicated with the circuit board, that consequently triggers the corresponding illuminant to emit light. The communication resilience members are guided and aligned through the alignment plate so as to avoid signal interference thereamong. Hence, the use of the control device not only illuminates to illustrate the touch positions, but also certainly prevents signal interference, so as to enable a more convenient operation.

Abstract: A lock, adapted for being assembled on a door panel, is provided. The door sheet has an assembling hole and a latch slot connected and communicated with the assembling hole. The lock includes a latch assembly, a first locking mechanism, and a second locking mechanism. The latch assembly is assembled in the latch slot and extended into the assembling hole. The first locking mechanism and the second locking mechanism are assembled in the assembling hole from the two sides thereof respectively to automatically position and affix the latch assembly. Because the latch assembly can be to led to move and positioned in the latch slot and the assembling hole by the first locking mechanism and no screw or other tool are required for fastening in the entire process of the assembling, the present invention is therefore easy and convenient to assemble.

Abstract: An electronic lock structure using a wireless charging device contains a power supply unit and an electronic lock unit. The power supply unit includes a variable-frequency drive and an AC/DC transformer. The electronic lock unit includes a battery and a rectification circuit, wherein the rectification circuit electrically outputs power of alternative current by way of a power receiving coil. When the power receiving coil is close to the power output coil, the power supply outputs the power to the electronic lock unit by using magnetic flux and to supply the power to the battery, thus charging the battery. When the power receiving coil is away from the power output coil, the power output coil does not conduct the power to the power receiving coil.

Abstract: Systems and methods electrically connect a first electronic device or electrical component, having a external electrical connector, to a circuit board of a second electronic device. A low-cost, user-installable connection system isolates mechanical stresses imposed on the external electrical connector to within the user-installable connection system, thereby preventing the mechanical stresses from reaching the circuit board in the second electronic device. If the connection becomes faulty, only the low-cost, user-installable connection system must be replaced.
