Example one

The embodiment relates to an electronic control auxiliary lock (hereinafter referred to as an electronic control auxiliary lock) with an unlocking function, which can be installed on a door body in a way of being matched with a main lock body 1 provided with a main lock bolt 10, wherein the main lock bolt 10 is arranged in the main lock body 1 and can extend out or retract into the main lock body 1. An exemplary structure of the electrically controlled secondary lock of the present embodiment is shown in fig. 1, and the electrically controlled secondary lock includes a secondary lock body 2 and a driving assembly provided in the secondary lock body 2. As shown in fig. 1 and fig. 2 and fig. 3, a cover plate 21 is provided on the secondary lock body 2 in a turned manner, the cover plate 21 and the secondary lock body 2 can enclose a lock hole 20 for inserting the primary bolt 10 therebetween in a locked and locked state, the driving assembly includes a driving source 23, a blocking portion 221 provided at a power output end of the driving source 23 and capable of forming the cover plate 21 to maintain the locked and locked state, and a limiting portion 211 abutting against the blocking portion 221 is provided on the cover plate 21 corresponding to the blocking portion 221, and the blocking portion 221 can be separated from the limiting portion 211 to release the locked and locked state of the cover plate 21 under the driving of the driving source 23, so that the cover plate 21 can be turned over toward the inner side of the door body around the turning center to open the door body.

Specifically, referring to fig. 1, one end of the cover plate 21 is turned over by a first pivot 27 provided on the bottom of the secondary lock body 2, and a stepped recess is formed at the other end of the cover plate 21 with respect to the pivotally connected end, and the recess constitutes the aforementioned stopper portion 211. In the locked and locked state of the cover plate 21, the cover plate 21 and the secondary lock body 2 form a lock hole 20 for the insertion of the primary bolt 10, wherein a connecting flap 22 is pivotally disposed on the secondary lock body 2, a flange extending along one side of the connecting flap 22 is formed at a free end of the connecting flap 22, i.e., an end opposite to the pivotal connection, and the flange can abut against the groove, and forms the blocking portion 221. The driving source 23 may receive an external signal and may have a linear reciprocating motion to pull the connection turning plate 22 to rotate, so that the blocking portion 221 may be separated from the limiting portion 211.

In order to facilitate the driving source 23 to pull the connecting turning plate 22 to realize the rotation of the connecting turning plate 22, in the embodiment, a transmission link 231 is hinged on the connecting turning plate 22, and the other end of the transmission link 231 is hinged to the power output end of the driving source 23 relative to the end hinged to the connecting turning plate 22.
