Title:
LOCKING DEVICE USING DOUBLE POWER GENERATION
Document Type and Number:
WIPO Patent Application WO/2021/107286
Kind Code:
A1
Abstract:
The present invention relates to a locking device using double power generation and, more specifically, to a locking device using double power generation, wherein inductive power generated by insertion of a smart key into a locking device for locking a locking target (for example, a drawer, a safe, or a door) is used to authenticate the smart key; if the authentication succeeds, an actuator is operated by electric power generated through physical power generation resulting from the insertion; and the locking device is accordingly unlocked by a key structure of the smart key. The present invention is advantageous as follows: electric power is generated through electromagnetic induction solely by inserting the key structure of the smart key, and electric power is generated by using mechanical power on the basis of the power used to insert the key structure; such double power generation supports sufficient supply of electric power necessary to drive the actuator for unlocking the locking device such that a stable unlocking process can proceed without external power supply; this prevents the locking device from malfunctioning or failing to operate, thereby guaranteeing reliability; and a simple structure regarding a locking device that operates powerlessly, thereby reducing the degree of complexity.
