Description

Plug-in intelligent electronic auxiliary lock

This creation is about an electronic lock, especially about a plug-in intelligent electronic auxiliary lock.

In recent years, the trend of smart homes is booming, and IoT furniture connected to smart devices is popular, including smart electronic locks.

Today's smart electronic locks use conductive belt and brush contact methods to control the opening and closing to determine the respective divided voltage values at the end of the conductive belt after rotation, and then measure the position of the position through the voltage coupling device The divided voltage value is used to further determine the angular position of the rotation of the intelligent electronic lock to determine whether the current electronic lock is in the open or closed position.

However, in such a conventional control method in which the brush contacts the conductive belt, mechanical friction between the brush and the conductive belt will inevitably continually occur, causing wear of the brush and the conductive belt in the material.
