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. The fixed shaft 5 is provided with a second torsion spring 6, one end of the torsion spring 6 is connected with the mask 1, and the other end of the torsion spring is connected with the mounting box 14. And a third torsion spring 15 is arranged on the mask unlocking shaft 4.

The working principle of the utility model is as follows:

as shown in fig. 1 and 2, when the vehicle has zero speed, the mask unlocking shaft 4 is rotated by 90 degrees by using a square hole key, the cylindrical pin 3 is disengaged from the hook 2, the mask 1 is rotated by 90 degrees along the fixed shaft 5 under the action of the second torsion spring 6, and the mask 1 is opened.

As shown in fig. 3-5, when the vehicle has zero speed, the mask 1 is opened, the stop driving mechanism 10, i.e. the electromagnet, is powered off, the stop 12 is contracted, the rotation path of the wire drawing disc 7 is released, and after the handle is pulled down and rotated by 90 degrees, the screw rod is pulled through the steel wire rope connected with the wire drawing disc 7, so that the door is unlocked.
