1. An information and electronic tail-controlled emergency backup unlocking mechanism, comprising:

  • the lock body and the cover, the lifting shaft piece, the half-shaft driven gear and the shifting pin, the secondary electronic emergency driving mechanism and the limiting moving piece mechanism are characterized in that a groove formed in the lock body provides the lifting shaft piece to move back and forth, shaft holes formed in the bottom of the lock body in sequence are respectively provided with the half-shaft driven gear and the emergency driving mechanism, and when the half-shaft driven gear arranged in the shaft holes is driven to rotate by a transmission gear of the emergency driving mechanism, the shifting pin arranged on the driven gear drives the lifting shaft piece to reciprocate along the groove of the lock body;

    the emergency driving mechanism which is a secondary electronic emergency driving mechanism and is meshed and linked with the semi-axis driven gear is provided with the same driving middle shaft which is respectively arranged in the shaft holes corresponding to the bottom and the cover part of the lock body, the middle shaft is provided with a jack type transmission device which consists of a middle shaft base wheel, a jack, an internal gear idler wheel with a limiting groove and a transmission gear, wherein the transmission gear on the driving middle shaft is meshed with the semi-axis driven gear to rotate, or the transmission gear arranged on the primary electronic emergency driving mechanism is meshed with the semi-axis driven gear and the transmission gear arranged on the secondary electronic emergency driving mechanism to rotate together or sequentially, so that a composite emergency interactive driving device is formed;

    in addition, one end of the driving middle shaft of the secondary electronic emergency driving mechanism serving as a power source, which is arranged outside the lock body, is connected through a motor, so that the power transmission effect is achieved;

    at ordinary times, the emergency driving mechanism is driven by only one motor to work, the middle shaft base wheel is driven to block the internal gear by a jack to transmit driving force to the fixed transmission gear, and then the transmission gear drives the half-shaft driven gear to rotate, so that the shifting pin arranged on the driven gear shifts the lifting shaft piece to reciprocate;

    the lifting shaft piece is provided with a transverse groove stress hole or a special-shaped stress groove hole which is suitable for the reciprocating driving of a poking pin on a driven gear, and one side in the lock body is also provided with a groove hole or a concave-convex folding angle type for the electronic identification position sensing device to identify;

    the limiting moving plate mechanism consists of a stopping clamping piece and a spring, wherein a pin hole at one end of the stopping clamping piece is arranged on a fixed pin column connected with the lock body and the cover, and the other end of the stopping clamping piece is clamped in a limiting groove of the internal gear idler wheel after being stressed by the spring or in a limiting groove of the excircle side of the composite idler wheel for preventing the locking idler wheel from returning, so that the locking idler wheel is prevented from reversing and achieving the locking effect of locking force.
