Description

Technical Field

[0001] The invention relates to the technical field of locks, in particular to a mechatronic electric lock body. Background Art

[0002] Locks have been a protective tool used by people to protect their property since ancient times. Locks have a long history. From traditional simple mechanical locks to today's various complex electronic locks, their protective functions are becoming more and more powerful, which is not only reflected in the improvement of the lock body structure strength, but also in the non-replicability of the unlocking process.

[0003] There are many types of locks on the market that are suitable for various scenarios, such as Korean stainless steel anti-theft door locks for civilian use, light luxury armored door / brass door locks, wide profile courtyard door locks; commercial security access control electric locks. For example, an application number of "201910726389.0" was retrieved on the China Patent Network, and the patent name is: electric lock body.

[0004] In this design, when the fork tongue retracts under the action of external force (when the electric lock body is installed on the door panel, the external force is the thrust of the door frame on the fork tongue), the second slide seat retracts into the lock body, and drives the locking member to rotate and toggle the positioning assembly, so that the positioning assembly cooperates with the first slide seat, so that the inclined tongue can be reliably tightened, so that the inclined tongue can reliably cooperate with the inclined tongue hole on the door frame, thereby achieving reliable positioning between the door installed with the electric lock body and the door frame, and finally making the door more reliably closed. When the motor drives the driven gear to rotate, the shift fork rotates and drives the first toggle tongue to toggle the positioning assembly, so that the positioning assembly is disengaged from the first slide seat, so that the inclined tongue assembly can move freely. Since the inclined tongue can be rotatably installed on the first slide seat, the electric lock body is then installed by pushing or pulling The electric lock body uses a locking assembly to drive a positioning assembly in a mechanical manner to achieve reliable positioning between the door and the door frame, thereby avoiding the situation where the door is not closed during a power outage. In addition, when closing the door, the elastic abutment between the fork tongue and the door frame acts as a buffer to reduce the rebound force between the door and the door frame, thereby avoiding the situation where the door is not closed due to excessive rebound between the door and the door frame. The driving motor drives the shift fork to rotate to achieve unlocking between the door and the door frame, thereby making unlocking more convenient.

[0005] Based on the advantages of the above design scheme and its superiority over traditional mechanical locks, here we propose another mechatronic electric lock body. Summary of the invention
