5) Within a certain time after the door is opened, the switch pin 8 can automatically pop out of the locking position inserted into the back locking sliding stop piece 5 to lock the knob component 3 in the positive unlocking direction, and the lock core is in a locking state.

The lock core can be applied to various types of lock cores, such as an external door lock core, a false inserting core lock core, a cabinet lock core, a glass door lock core and the like. Fig. 6 and 7 show a structure diagram and an explosion diagram of a cabinet lock cylinder, fig. 8 and 9 show a structure diagram and an explosion diagram of a glass door lock cylinder, and fig. 10 and 11 show a structure diagram and an explosion diagram of a room door false insertion core.

Above-mentioned intelligent access control system launches wireless charging signal through set up wireless emitter that charges on the door frame, and when the door leaf closed in the door frame, the inside wireless receiving arrangement that charges of lock core that sets up on the door leaf can receive this wireless charging signal to charge the circuit board of lock core, do not need frequent change the battery. Meanwhile, an electronic device is implanted into the traditional mechanical lock cylinder by transforming the mechanical lock cylinder on the basis of the structure, so that the mechanical lock cylinder not only keeps the original function of opening the door by using a mechanical key, but also can control the door to be opened by using a mobile phone, the mechanical lock cylinder is changed into a lock cylinder which can be connected and controlled by using the mobile phone, the appearance is consistent with the mechanical lock cylinder, the replacement and the installation are convenient, and the cost is lower.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
