AI Technical Summary

Technical Problem

Existing electric partition doors are difficult to open manually when power is off because the drive mechanism and locking mechanism cannot be reliably disengaged. This poses a safety hazard and does not comply with the safety principle of allowing escape during power outages.

Method used

The system employs a coordinated control system of clutch drive mechanism and clutch locking mechanism. The control unit disconnects the drive mechanism's transmission connection after the partition door is in place and automatically disengages in the event of an unexpected power outage, ensuring that the user can manually open the door.

Benefits of technology

It enables smooth manual opening of the partition door in the event of a power outage, improving the inherent safety and emergency reliability of the system and avoiding the problem of difficulty in manual opening caused by the inability of the drive and locking mechanisms to reliably disengage.

Abstract

The present application relates to the technical field of partition doors, and provides a partition door power-off self-releasing clutch safety control system, through the cooperative control of a clutch driving mechanism and a clutch locking mechanism, after the partition door is operated to the position, the control unit cuts off the transmission connection of the clutch driving mechanism, and the locking action is realized through the power-on of the second clutch mechanism; the locking state is maintained by the mechanical structure itself, rather than relying on the continuous power-on maintenance; when the main power is unexpectedly powered off, the second clutch mechanism is automatically disengaged, the power constraint of the motor on the locking mechanism is released, at this time, even if the partition door is in the locked position, the user can also make the door body unlock and move through manual pushing and pulling, without additional operation or tools; at the same time, the control unit ensures that the clutch locking mechanism is always in a releasable state during the movement of the partition door, effectively avoiding the mislocking. The design fundamentally solves the problem of difficult manual opening of the existing electric partition door due to the fact that the driving and locking mechanisms cannot be reliably disengaged after power-off.
