Electronic lock cylinder

Abstract

The invention discloses an electronic lock cylinder. The electronic lock cylinder comprises a shell, and a motor module, a control module for controlling the motor module to operate and a lock tonguebody connected with the motor module, which are positioned in the shell; the lock tongue body comprises a lock tongue cavity, and a lock tongue arranged at the lower part of the lock tongue cavity; and a rotating spring is arranged in the lock tongue cavity. The motor module comprises a driving motor and a rotating shaft; the driving motor is connected with the rotating shaft; and the rotating shaft penetrates through the lock tongue cavity, and sleeves the rotating spring. When the driving motor is rotated forwards or reversely, the rotating shaft is rotated to drive the rotating spring to rotationally compress or stretch; and the rotating spring is compressed or stretched to deform to drive the lock tongue body to move up and down in the axial direction of the rotating shaft so as to achieve the purposes of unlocking and locking. The electronic lock cylinder is simple in electromechanical composition structure, precise in lock tongue operation control, low in power consumption, low in fault rate and long in service life.

Description

technical field [0001] The invention belongs to the field of locks, in particular to an electronic lock cylinder. Background technique [0002] The lock cores adopted in the prior art are mainly mechanical lock cores and electronic lock cores, and the unlocking of the mechanical lock cores must be unlocked by a key, and there is a situation that the key cannot be unlocked due to the omission of the key. This problem can be avoided by using an electronic lock cylinder. [0003] In the prior art, most of the electronic lock cylinders have an integrated structure, which is difficult to disassemble and maintain, and there are many internal components, complex electromechanical structures, and inaccurate operation control of the lock tongue, resulting in high power consumption, high failure rate and long service life. issues such as short lifespan. In addition, it is also desired to provide an electronic lock cylinder with strong versatility, so as to be applicable to many diff...
