Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-7, the emergency unlocking device in a passenger compartment door system vehicle of the present invention comprises a mounting box 14, a panel assembly is arranged on the front side of the mounting box 14, a rotatable wire drawing disc 7 is arranged behind the panel assembly in the mounting box 14, and a handle 8 is arranged on the wire drawing disc 7; the back of the mounting box 14 is provided with a stopper driving mechanism 10, the stopper driving mechanism 10 is connected with a stopper 12, and the stopper 12 can extend out and block the wire drawing disc 7 or shrink without blocking the wire drawing disc 7 under the driving of the stopper driving mechanism 10. The stopper driving mechanism 10 is an electromagnet. A stop block 9 is arranged at the back of the wire drawing disc 7 in the mounting box 14. The stop 9 is connected to a mounting box 14 via a handle return shaft 13. The handle reset shaft 13 is provided with a first torsion spring 11.
The panel component comprises a face mask 1, the face mask 1 is connected with a mounting box 14 through a fixing shaft 5, and a locking mechanism is arranged between the face mask 1 and the mounting box 14. The locking mechanism comprises a clamping hook 2 arranged on the face mask 1 and a clamping pin 3 which is arranged on the mounting box 14 and matched with the clamping hook 2, and the clamping pin 3 is connected with a face mask unlocking shaft 4.
