TABLE 1
The above-described response to the closing of the door may be achieved manually or automatically. In a manual mode, the door opening instruction can be obtained by setting a door opening switch; and in the automatic mode, the corresponding door opening instruction can be obtained through human body identification, infrared, sound control, light control and other modes. The door can be closed manually or automatically. In the automatic mode, the mode shown in fig. 3 may be further selected, and the door body is automatically driven to close within the time range of the interval STOP after the door is opened.
Take the automatic opening and closing door shown in fig. 3 as an example. After receiving a door opening signal, the unlocking driving piece and the driving device rotate in a first direction and a first driving direction respectively. And a motor A corresponding to the unlocking driving piece drives the driving gear to push the rack out to a return control head position of 30mm through each transmission gear, and the idle rotation positioning is carried out in a first state. When the driving device 21 is operated, the electromagnetic clutch 41 attracts and links the loose gear 22, and transmits the torque in the first driving direction output by the driving device 21 to the door connecting device 23 to drive the door to open. In the opening process, the signal control wheel 51 rotates along with the door body connecting device 23, the angle corresponding to 0 degrees gradually rotates to the angle corresponding to 120 degrees, the pressing rod 52 connected to the inside of the signal control wheel falls into the recess of the inner wall of the cam within the angle range of 120 degrees, the second end of the pressing rod 52 is driven by the elastic piece connected to the second end of the pressing rod to rotate to the set angle range, and the switch 53 is triggered by the second end of the pressing rod 52 to output a first electric signal to indicate that the door body is opened. At this time, the door opening operation is completed, and the drive can be turned off.
After the door body is opened, the door closing action is automatically triggered after a preset STOP time interval. During the door closing process, if the rack is still in the extended state, the rack can be driven to retract to the position of the other end return control head 31 by unlocking the driving piece to drive the rack in the second direction (for example, corresponding to the motor a reversing the CCW), so that the rack is retracted to the inside, and the door closing is prevented from being influenced. In order to drive the door to close, the driving device 21 operates in the second driving direction (for example, corresponding to the motor B reversing CCW), the electromagnetic clutch 41 is engaged, and transmits the torque in the second driving direction to the door connecting device 23 to drive the door to close. The door closing angle is also obtained by the signal control wheel 51 rotating together with the door connecting device 23. The signal control wheel 51 rotates to an angle corresponding to 0 degree from an angle corresponding to 120 degrees gradually, the pressing rod 52 connected to the inside of the signal control wheel operates to a step on the inner wall of the signal control wheel 51 at the corresponding angle, the second end of the pressing rod 52 is driven by the step and exits from the set angle range, and the switch 53 is released from the second end of the pressing rod 52 and returns to a second electric signal to indicate that the door body is opened.
In one implementation, to avoid the switch being turned on all the time to pass current, the second electrical signal can be set to ground or low level to prolong the life of the switch and reduce the power consumption of the system. At this time, the door opening operation is completed, and the drive can be turned off. And the corresponding first electrical signal may be set to a high level.
When the electromagnetic clutch 41 is disengaged from the attraction, the transmission relationship between the door body and the driving device is disconnected, and the door can be opened and closed manually, so that the electromagnetic clutch can be automatically disengaged from the attraction after the door body is opened or closed or within a proper time of the door opening and closing driving output, and the phenomenon that a user pushes the door body to reversely apply an acting force to the driving device 21 when the user manually closes or opens the door is avoided, and the door is protected from being damaged by the reverse action.
The above description is only for the embodiments of the present invention, and the description is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several changes and modifications can be made, which all fall within the scope of the present invention.
