A deflector rod 9 is fixed on the rotating shaft 2, the handle 3 is connected with an unlocking rod 10, and the deflector rod 9 can be driven by the unlocking rod 10.

As an embodiment of the out-of-the-flat handle of the present invention: as shown in fig. 5 to 9, an actuating rod 11 is hinged on the base 1, the actuating rod 11 is hinged with the handle 3, the unlocking rod 10 is hinged with the handle 3, a push rod 12 is slidably arranged on the base 1, the head of the push rod 12 is contacted with the tail of the unlocking rod 10 to push the unlocking rod 10, the tail of the push rod 12 is contacted with the actuating rod 11 to push the actuating rod 11, a guiding structure for guiding the push rod 12 and the unlocking rod 10 is arranged on the base 1, and a driving mechanism for pushing the push rod 12 to slide is further arranged on the base 1. The drive mechanism includes a motor and a lead screw coupled to the push rod 12. The guide structure comprises a guide groove 13 arranged on the base 1, and guide posts 14 sliding in the guide groove 13 are arranged on the unlocking rod 10 and the push rod 12. As shown in fig. 1, the guide groove 13 on the front surface and the guide groove 13 on the rear surface are provided inside the base 1.

Working principle:

the initial position of the handle is a hidden position shown in fig. 5 and 6, the driving mechanism drives the push rod 12 to move after receiving a certain instruction, the push rod 12 pushes the actuating rod 11 and the unlocking rod 10 to act, under the limit of the guide groove 13, the handle is flat and reaches the unfolding position, as shown in fig. 7, the push rod 12 is in contact with the unlocking rod 10 and the actuating rod 11 in the drawing, the push rod 12 is not shown in the stretching state of fig. 7, the trigger piece 4 does not trigger the micro switch 8, then a human hand can pull the handle 3 to rotate a small angle from the unfolding position through a small force, as shown in fig. 8, the trigger piece 4 triggers the micro switch 8, the electronic unlocking can be realized, the door can be opened by continuously pulling the handle 3, and under normal conditions, the manual emergency unlocking door opening is not needed, and the pulling force for pulling the door after the electronic unlocking is also small, which is far smaller than the pulling force required by the emergency mechanical unlocking. After the door is opened, the handle 3 is driven to gradually return through the rotating shaft 2 under the torsion action of the first torsion spring 6.

Emergency unlocking: when the power is off or the micro switch 8 does not respond to emergency conditions, the handle 3 is pulled out by a hand and is rotated by a larger angle relative to the electronic unlocking, the lug 21 at the second end of the rotating shaft 2 starts to drive the load part 5 to rotate after rotating the idle stroke, and the trigger part 4 pulls the door opening inhaul cable to unlock after continuing to rotate a certain angle, so that manual emergency unlocking is realized, as shown in fig. 9. Since the contact surface of the trigger piece 4 and the reed of the micro switch 8 is set as the cylindrical surface 41, the center of the cylindrical surface 41 coincides with the center of the rotating shaft 2, the cylindrical surface 41 is tangent to the reed in the continuous rotation process of the trigger piece 4, no further stroke is generated on the reed of the micro switch 8, and the two cannot interfere. Resetting: under the torsion action of the second torsion spring 7 and the first torsion spring 6, the rotating shaft 3 firstly returns to the position of electronic unlocking as shown in fig. 8, at the moment, the load piece 5 is limited to be no longer operated, and the handle 3 is driven to gradually return through the rotating shaft 2 under the torsion action of the first torsion spring 6.

The present invention is not limited to the above-mentioned embodiments, and any person skilled in the art, based on the technical solution of the present invention and the inventive concept thereof, can be replaced or changed within the scope of the present invention.
