Drive device for lock pin

Abstract

The invention discloses a lock cylinder driving device, which comprises a micro-motor, a pendant, a bracket, and a drive output shaft. The swing of the ornament drives the bracket and drives the output shaft to move. The present invention has simple structure, convenient backup, and it is easy to form multiple sets of independent backup components without increasing the volume; the failure rate of locks using this mechanism is greatly reduced, and the reliability is greatly improved, so that the lock core of the present invention can be directly integrated into car doors and households. Anti-theft doors, safes, etc., are directly compatible with various electronic control systems, and the application is simple and has a wide range of applications.

Description

【Technical field】: [0001] The invention relates to a lock cylinder driving device. 【Background technique】: [0002] Electronic lock is a new type of lock that is more and more widely used, and it is an updated product of traditional mechanical lock. [0003] The electronic locks currently on the market, whether they work with AC or DC, generally have a working power consumption of several watts (W) to tens of watts (that is, the working voltage is mostly 12-24V, and the working current is 0.2-2A). Due to low efficiency and high power consumption, this type of electronic lock requires a large capacity of the power supply system, so it cannot match the microelectronic control circuit with continuously reduced volume, weight, and power consumption, which also leads to very strict or frequent power consumption requirements in some applications. It is almost impossible to apply in the occasion of power failure, which restricts the popularization and replacement of electronic con...

[0003] The electronic locks currently on the market, whether they work with AC or DC, generally have a working power consumption of several watts (W) to tens of watts (that is, the working voltage is mostly 12-24V, and the working current is 0.2-2A). Due to low efficiency and high power consumption, this type of electronic lock requires a large capacity of the power supply system, so it cannot match the microelectronic control circuit with continuously reduced volume, weight, and power consumption, which also leads to very strict or frequent power consumption requirements in some applications. It is almost impossible to apply in the occasion of power failure, which restricts the popularization and replacement of electronic control locks. Therefore, the application of electronic locks has been limited to high-end commercial places such as hotels and office buildings, and cannot be widely used in homes; Driven by a motor, it is driven by gears and racks. The electromechanical structure is relatively complex, and installation and maintenance require certain professional skills, which is difficult; the entire mechanism consumes high power, and when a fault occurs, the motor self-locking will block the entire mechanism , so this type of electronic lock must be equipped with an ordinary mechanical unlocking mechanism

For the existing ordinary mechanical lock, if it is to be converted into an electronic lock, the entire lock can only be replaced in the prior art, so it cannot be well integrated with the traditional mechanical lock, the replacement cost is high, and it is not conducive to popularization and application.
