Manual-automatic integrated intelligent door shaft system

Abstract

The invention relates to a manual-automatic integrated intelligent door shaft system, which includes two fixed pivots coaxially and vertically arranged on an upper door frame and a lower door frame. Abracket is fixed in a door leaf, a motor and an intermediate rotating shaft which are in transmission fit are both installed and arranged in the bracket, the tail end of the intermediate rotating shaft meshes with one of the fixed pivots through a gear, an intermediate disc movably sleeves the intermediate rotating shaft, the motor is connected with the intermediate disc in a transmission mode, atransmission route passes through a worm and gear pair, the intermediate disc and the intermediate rotating shaft are in transmission fit through a damping friction pair, and a blocked skid mechanismis formed. According to the manual-automatic integrated intelligent door shaft system, if the door leaf is hindered in the electric opening and closing process, the intermediate rotating shaft also stops relatively, due to the fact that the transmitted torque of the worm and gear pair is large, the damping friction pair between the intermediate disc and the intermediate rotating shaft can immediately skids, the motor idles, and that is, the door leaf can be pushed and blocked at will, and opened and closed manually as ordinary doors. The manual-automatic integrated structure is reasonable andcompact, the safety is good, the manual-automatic integrated intelligent door shaft system is not affected by vibration, dust and other effects, and the reliability is high.

Description

[0001] Technical field: [0002] The invention relates to an electric door, in particular to a rotating door shaft system for the electric door. [0003] Background technique: [0004] Many electric doors are driven by a built-in motor installed in the door leaf, but the door leaf rotation center still uses a hinge connected to the side. After long-term use or strong pulling, the door leaf is prone to tilting and falling. In the process of electric opening and closing, in order to prevent the human body from being caught or other obstacles, sensors are generally used to monitor, and when the human body is caught or there is a heavy obstacle, the motor is instructed to stop immediately. However, the sensor itself is easily disturbed by vibration, dust, etc., and there are many induction faults, and it is easy to block the door leaf and burn the motor. Moreover, in real life, people often reach out to block the door or push back the door leaf for various reasons when entering an...

AI Technical Summary

Problems solved by technology

However, the sensor itself is easily disturbed by vibration, dust, etc., and there are many induction faults, which may cause the door leaf to be blocked and the motor to be burned.

Moreover, in real life, people often reach out to block the door or push back the door leaf for various reasons when entering and exiting the door. Although the electric door can be opened and closed automatically, it cannot be pushed and blocked at will like ordinary doors. Can't satisfy people's long-term habits
