Transmission mechanism special for intelligent door lock

Abstract

The invention discloses a transmission mechanism special for an intelligent door lock. The transmission mechanism aims at being compact in structure, stable, reliable and high in safety. The transmission mechanism comprises an outer side transmission mechanism, an inner side transmission mechanism, a motor and a clutch, wherein the outer side transmission mechanism comprises an outer panel, an outer handle, a first gear, a first chain, a second gear and a first transmission sleeve, the inner side transmission mechanism comprises an inner panel, an inner handle, a third gear, a second chain, afourth gear and a second transmission sleeve, a first transmission shaft is arranged between the outer side transmission mechanism and the inner side clutch transmission mechanism, an outer handle rotating shaft and the outer panel are perpendicular to each other and can rotate relatively, the first gear and the second gear are in transmission connection through the first chain, a protruding shaftis arranged on the front face of the second gear, the first transmission sleeve is fixed on the reverse side of the second gear through screws, the face, perpendicularly facing a lock body, of the third gear is a reverse face, the third gear and the fourth gear are in transmission connection through the second chain, and the second transmission sleeve is fixed to the reverse side of the third gear through screws.

Description

technical field [0001] The invention relates to the transmission technical field of a rear clutch of an intelligent lock. Background technique [0002] Most of today's smart locks use a front clutch, which has the advantage of low cost, but also has the defect that it is easy to be opened by technology. Because the clutches of most of the existing electronic door locks are all installed on the inner side of the outer handle panel of the electronic door lock, criminals can use the connection between the door body and the handle outside the door to use professional sheet tools to directly Put it into the gap and turn the unlocking shaft to open the door; or use an electric drill to make a small hole at the position of the clutch electronic control unit in a short time, and then use a steel needle to move the clutch of the clutch to fast, that is The door can be opened; the outer handle can be forcibly rotated, and the door lock can be opened. Now there are more than ten kind...

AI Technical Summary

Problems solved by technology

Now there are more than ten kinds of defects that utilize the front clutch, and the method of opening the smart lock can be technically opened in a few seconds. According to this, the safety factor of the existing smart door lock with the above-mentioned structure is not high enough, and now a kind of The transmission mechanism of the smart lock with high security and anti-opening by external technology
