Automatic door opening and closing device with torque induction and automatic clutch

Abstract

The invention belongs to the technical field of smart home, and discloses an automatic door opening and closing device with torque induction and automatic clutch. The device comprises a clutch output gear, the middle part of the clutch output gear is movably sleeved with an upper clutch plate, the upper side of the middle part of the upper clutch plate is movably sleeved with a clutch fixing ring, an electromagnetic coil is fixedly installed on the top of the lower end of the upper clutch plate, a tower spring is fixedly connected to the bottom of the upper clutch plate, a lower clutch plate is fixedly connected to the lower end of the tower spring, a permanent magnet is movably connected into the lower end of the lower clutch plate in a sleeved mode, and a clutch input gear is fixedly connected into the lower clutch plate in a sleeved mode. The anti-pinch function is achieved by arranging a pressure shaft, an elastic body, a resistance strain gauges and the like, the clutch output gear can rotate freely by arranging the upper clutch disc, the electromagnetic coil, the tower spring and the lower clutch disc, the clutch output gear can rotate freely, then a connecting rod mechanism can rotate freely, and the anti-pinch function is achieved.

Description

technical field [0001] The invention belongs to the technical field of smart home, in particular to an automatic door opener with torque sensing and automatic clutch. Background technique [0002] With the development of science and technology, intelligent locks have been widely used, but there are two main types of automatic door closers on the market: one is the horizontal track type that can only be used for sliding doors with tracks, and the other is the spring or hydraulic type. It is suitable for hinged doors, but it can only play a one-way action of closing or opening the door and does not have functions such as anti-clamping. [0003] In addition, the output shaft of the deceleration motor on the market cannot move freely or requires a large torque to rotate due to the influence of the reduction mechanism. If the reduction ratio is high, it cannot rotate freely. The motor can only drive the output shaft to rotate through the reduction gear, reducing gear life. Con...
