Double-clutch device for high-safety electronic lock and electronic lock

Abstract

The invention discloses a double-clutch device for a high-safety electronic lock and an electronic lock. In order to solve the problems that an existing electronic lock can be unlocked by damaging a mechanical lock cylinder or an outdoor panel of the electronic clock and safety risks exist, the double-clutch device comprises a motor, a first clutch transmission gear driven by the motor, a driven gear, an inside door handle transmission gear, a driving gear and a second clutch transmission gear, wherein the driven gear is in engaged transmission with the inside door handle transmission gear; the first clutch transmission gear can be in the engaged transmission with the driving gear and the driven gear at the same time; the second clutch transmission gear can be in the engaged transmission with the driven gear and the driving gear at the same time; the driven gear drives a driven output shaft to rotate so as to drive a lock tongue of an existing mechanical lock body to stretch out or retract back to realize locking or unlocking. According to the double-clutch device for the high-safety electronic lock and the electronic lock, a standard double-quick mechanical lock body can be directly replaced or the standard double-quick mechanical lock body is used for forming a high-safety anti-theft electronic lock in a combining way and mounting positions of inner and outer panels of the lock are changed; the double-clutch device is suitable for upgrading almost common mechanical lock bodies into the electronic locks.

Description

technical field [0001] The present invention relates to a lock, and further refers to a double clutch device and an electronic lock for a high-safety electronic lock that can directly use a standard double fast mechanical lock body or a common mechanical lock body. Background technique [0002] In the existing technology, common door locks include mechanical locks, electronic (card sensor, fingerprint, password, etc.) locks, etc. With the improvement of living standards and safety protection requirements, many places need to upgrade the original mechanical locks to electronic locks , but often in the process of replacing it with an electronic lock, because of the gap between the current electronic lock and the original mechanical lock installation hole, it is generally impossible to directly replace it. It is necessary to re-open the hole on the door and adjust the installation position. The installation is more difficult and will cause Reduce the strength of the original do...

Problems solved by technology

[0002] In the existing technology, common door locks include mechanical locks, electronic (card sensor, fingerprint, password, etc.) locks, etc. With the improvement of living standards and safety protection requirements, many places need to upgrade the original mechanical locks to electronic locks , but often in the process of replacing it with an electronic lock, because of the gap between the current electronic lock and the original mechanical lock installation hole, it is generally impossible to directly replace it. It is necessary to re-open the hole on the door and adjust the installation position. The installation is more difficult and will cause Reduce the strength of the original door panel

In addition, the lock handle (door handle) on the general electronic lock door is in a semi-free state, that is, there is only a certain free rotation angle in one direction or two directions, and it is very easy to be damaged by external force or encounter violent unlocking, and the security of the lock is poor.

Moreover, the clutch device for upgrading the electronic lock by using the mechanical lock body of the anti-theft door is installed on the outer panel of the lock, and the electronic lock can be opened only by destroying the outer panel, which has potential safety hazards.
