Electromagnetic lock, lock cylinder of electromagnetic lock and unlocking method for electromagnetic lock

Abstract

The invention provides a lock cylinder. The lock cylinder comprises a high-end part, a low-end part and a brake unit, wherein the high-end part of the lock cylinder is provided with a brake chamber extending from top to bottom and a positioning cavity extending horizontally; the positioning cavity is communicated with the brake chamber; the brake chamber of the high-end part of the lock cylinder is provided with a lateral wall and forms a limiting position; the brake unit comprises a brake part arranged inside the positioning cavity of the high-end part of the lock cylinder, a reset part arranged on the brake part and extending from the brake part horizontally, and a limiting bolt; the limiting bolt is arranged on the lateral wall of the brake chamber in a pivoted mode. The invention further provides an unlocking method for an electromagnetic lock.

Description

technical field [0001] The invention relates to an electromagnetic lock, in particular to an electromagnetic lock whose lock body does not need to be provided with an energy storage mechanism such as a battery. Background technique [0002] Existing locks or locksets can be classified into mechanical locks and electronic locks. Traditional mechanical locks are coded by mechanical pins. The unlocker only needs to insert the key into the lock hole of the lock cylinder and turn the lock cylinder through a mechanical force, so that the lock beam of the locked lock can be separated from the lock body and unlocked. The unlocking of this traditional mechanical lock only requires a key with a specific geometric shape, and does not need to confirm the authorization of the unlocker, so that the unlocker only needs to imitate a key with a corresponding shape, or an unlocking tool to open it. Therefore, the safety of this traditional mechanical lock is low, and it is difficult to reali...

AI Technical Summary

Problems solved by technology

Since the energy storage of the energy storage unit takes a certain amount of time, the response time of the electronic lock is relatively slow

Secondly, the service life of the known energy storage unit is far lower than the electronic circuit and mechanical structure in the lock body. Once the service life of the energy storage unit is exhausted, the electronic lock will not be able to be used normally, so the life of the entire lock is limited.

In addition, the electronic lock taught by this invention patent requires a mechanical force provided by the motor and a linkage mechanism that transmits the mechanical force to realize the unlocking and locking of the lock, which increases the complexity of the internal structure of the lock, while the linkage mechanism that transmits the mechanical force Wear and tear of the motor, brush aging, stuck, wear, poor contact and damage to the deceleration mechanism will also lead to a further reduction in the overall life of the electronic lock

In addition, considering that the volume of the motor with corresponding output power is relatively large, this will lead to an increase in the volume of the lock, and the application range is limited

Finally, the signal control circuit taught by the invention includes a signal / power separation unit, a signal shaping unit, a signal superposition unit, a voltage stabilizing unit, an energy storage unit, etc., and its circuit structure is complex, making it difficult to miniaturize the lock
