Intelligent electronic lock with clutch structure

The invention relates to an intelligent electronic lock clutch structure, belonging to the technical field of locks.

Background technique

At present, the existing smart locks and electronic locks are constructed by mounting motors, screws, cams, springs, etc. on the lock body. This structure works as follows. When the door lock receives the signal, the motor in the lock body begins to rotate. At this time, the screw is used to convert the circular motion of the motor into a linear motion of the screw, and then the linear motion of the screw is used to push the thin rod out. Finally, the square hole of the lock body is caught by the thin rod that is ejected, so that the square hole and the lock cylinder remain relatively stationary. Then, when the handle is turned, the square hole can be rotated by the square column to rotate the lock cylinder together to achieve the purpose of opening the door.

The structure of the intelligent lock and the electronic lock is mechanically integrated, and the mechanical part of the lock body can be better operated by an external electric signal, thereby achieving the purpose of electronically controlling the door lock.

The above structure is modified in the lock body. The working mode of using the motor is called the motor mode. The lock body using this type of work is called the motor type lock body.

In the process of installing the motor type lock body, not only the lock case needs to be disassembled, but also the original lock body needs to be disassembled. The shape of the motor-type lock body and the original lock body are often different in size, which requires irreversible modification of the door body during installation so as to be able to be placed in the motor-type lock body. This makes the motor type lock body have poor versatility, high damage to the door body, complicated installation process, and high maintenance difficulty. At the same time, when the motor type lock body uses the motor as the power source, the triggering and rotation of the motor have hysteresis, so that the unlocking action made by the lock body after receiving the door opening command is not timely, which affects the user experience.

Summary of the invention

The object of the present invention is to overcome the defects of the above technology, and provide a clutch type structure of an intelligent electronic lock, so as to damage the door body during installation and modification, and can facilitate maintenance, and avoid the hysteresis effect of the motor triggering and turning, and improve the door opening action.
