Position control device for main tongue of lock body with rotary encoder

Abstract

The invention discloses a position control device for a main tongue of a lock body with a rotary encoder. The position control device comprises a device body, and a driving motor component, the rotaryencoder, a position detection gear and the main tongue are arranged in the device body. The position detection gear is arranged on one side of a shifting fork, and the rotary encoder is arranged on the position detection gear. The driving motor component is fixedly arranged on one side of a shifting fork gear, and the shifting fork is arranged in the shifting fork gear. The main tongue is arranged on one side of the shifting fork gear, and a shifting fork spring is fixedly arranged on one side of the main tongue. The position control device also comprises a plug-proof tongue, a horizontal support is arranged at one end of the plug-proof tongue, and a plug-proof tongue microswitch is fixedly arranged on the horizontal support. The position control device has a simple structure principle, adopts the rotary encoder to detect the position of a shifting fork driving gear, and therefore realizes the detection for the unlocking and locking positions of the main tongue and the zero position of the shifting fork driving gear.

Description

technical field [0001] The invention relates to the technical field of lock body control, in particular to a lock body main tongue position control device using a rotary encoder. Background technique [0002] Smart locks refer to locks that are more intelligent in terms of user identification, security, and management, which are different from traditional mechanical locks. The smart lock is the executive part of the door lock in the access control system; the current smart lock is different from the previous "open first and then scan" method, the scanning method is very simple, just put your finger on the top of the scanning place and scan from top to bottom , No need to press your finger on the scanning place, the scanning method reduces fingerprint residue, greatly reduces the possibility of fingerprints being copied, safe and exclusive. [0003] Chinese patent number 201610167709.X, and at the same time declared the invention, patent number 201620224098.3. The above-men...

Problems solved by technology

The above-mentioned patent adopts four switches to detect and control the movement of the main tongue, and uses a photoelectric switch to detect the position of the main tongue, which has high requirements on the position accuracy of the photoelectric switch, which is prone to errors and leads to the failure of the switch lock, and the components are relatively heavy. Many, many failure points
