Abstract

The utility model discloses a transiently-driven remotely-controlled electronic lock which aims to overcome the defects that the prior remotely-controlled electronic lock is easy to heat to be damaged due to long conduction time and provides a fault-free remotely-controlled electronic lock with high work reliability. The utility model adopts the main technical scheme that a brake notch or a hole is arranged on a lock lever, and an electromagnet is mounted aiming at the position of the brake notch or the hole; one inserted tip of the electromagnet is in a conical shape or a wedge shape, and the other end of the lock lever is provided with an offsetting spring of the lock lever. Due to the adoption of the structure, an unlatched output digital decoding circuit is adopted as a remotely-controlled digital decoding circuit to control the electromagnet, and a transient driving mode is adopted to control the attracting action of the electromagnet so as to effectively improve the fault-free work reliability of the lock.

Description

The Remote control electronic lock that a kind of transient state drives

Technical field the utility model is a kind of lock, the Remote control electronic lock that a kind of transient state of more specifically saying so drives.

The present known Remote control electronic lock of background technology, use the adhesive of electromagnet mostly and reset and finish the action of unblanking or lock, the adhesive of electromagnet and resetting by the control of the coding-decoding circuit of remote control, because the operating current of electromagnet is bigger, therefore not only power consumption is bigger when electromagnetic actuation, and because its conduction time is longer, electromagnet usually damages because of heating, and the no-failure operation reliability of lock is affected.

Summary of the invention the utility model discloses the Remote control electronic lock that a kind of transient state drives at above-mentioned defective.

The technical solution of the utility model is: the Remote control electronic lock that described transient state drives, mainly comprise lock housing, electromagnet, electron key, control circuit, locking bar, the locking bar back-moving spring, lock pin, the lock pin back-moving spring, lock pin frame, lock pin frame back-moving spring etc., described electron key is made up of digital coding circuit and radio transmitter, the output of digital coding circuit connects radio transmitter, and described control circuit is made up of digital decoding circuit and wireless receiving circuit, and the input of digital decoding circuit connects wireless receiving circuit, the digital decoding circuit of control circuit described in the utility model is the digital decoding circuit of unlatching output, its output connects the drive circuit of electromagnet, controls the adhesive of electromagnet in the mode of transient state driving and moves, and described electromagnet is mainly by electromagnetic coil, bolt-type moves iron core, compositions such as moving iron core return-spring.

The utility model is different according to lock body structure and use occasion, when for example being used for different occasion such as various locks, door lock, bin lock, following three kinds of different embodiment can be arranged:
