In an embodiment, in order to clearly describe the technical solution of the present application in detail, the present embodiment describes the working process of the entire intelligent door lock in detail, and the door opening method of the entire intelligent door lock includes three door opening methods, first, a voice door opening method is introduced, as shown in fig. 2, when a person approaches to a sensing device, the sensing device 600 acquires human body sensing information, and then triggers the information obtaining device 100 to obtain unlocking information, for example, when the person speaks to the intelligent door lock, the information obtaining device 100 acquires voice information as unlocking information, compares the voice information with preset verification information to obtain a verification result, and then sends the verification result to the control device 200, and at the same time, the image collecting device 400 also collects video images of the environment around the intelligent door lock, obtains image information, and uploads the image information to the server through the wireless communication device 500, after the verification result is obtained, the control device 200 sends a corresponding control signal, such as an unlocking control signal or a locking control signal, to the key cylinder 300.

As shown in fig. 3, when receiving an unlocking control signal, the electronic bolt 38 in the lock cylinder will pop out from the through hole, that is, the lock shaft 36 is unlocked, at this time, the user can directly rotate the knob 32, then the knob 32 drives the lock cylinder 33 and the pull tab 35, and further, the pull tab 35 pulls the lock tongue to extend out from the limit mechanism of the door frame, thereby realizing the door opening; if the electronic latch 38 receives the locking control signal, it will not pop out of the through hole, i.e. the lock shaft 36 will remain locked, and the user cannot open the door by turning the knob 32.

The second door opening mode is that a conventional key is inserted to open a door, referring to fig. 3, the key 31 is inserted into a keyhole of the knob 32 and enters the lock cylinder 33, when the key 31 is matched with blades in the lock cylinder 33, the key 31 can rotate to drive the clutch rotating member 34 to move forward, so that the front part of the lock cylinder (the knob 32, the lock cylinder 33 and the pull-drag 35) and the lock shaft 36 are in a separated state, and at the moment, a user twists the knob 32 to drive the pull-drag 35, so that the pull-drag 35 pulls the lock tongue to move, thereby realizing door opening. It should be noted that, because the lock shaft 36 has a through hole, the electronic bolt 38 is normally inserted into the through hole, so that the lock shaft 36 is locked and cannot rotate, and therefore, in a normal situation, when a key is inserted, the clutch rotating member 34 needs to move forward, so that the front part of the lock cylinder (the knob 32, the lock cylinder 33 and the pulling piece 35) and the lock shaft 36 are in a separated state, and the front part of the lock cylinder can rotate, and when rotating, the pulling piece 35 is driven to pull the lock tongue to move, so as to open the door.

The third mode of opening the door is through user wireless control, for example, a user uses a mobile phone to perform wireless communication (for example, bluetooth wireless communication) with the antenna assembly 40 of the wireless communication device 500, the antenna assembly 40 is connected to the information acquisition device 100, the user can send a wireless unlocking instruction to the antenna assembly 40 through the mobile phone, the antenna assembly 40 forwards the wireless unlocking instruction to the information acquisition device 100, then the information acquisition device 100 compares and verifies the wireless unlocking instruction with preset verification information to obtain a verification result, and sends the verification result to the control device 200, after obtaining the verification result, the control device 200 sends a corresponding control signal to the lock cylinder, for example, an unlocking control signal or a locking control signal, the subsequent flow is similar to that in the first unlocking mode, and details are not repeated here. It can be understood that, in the third door opening mode, a power supply is required to enable the antenna assembly 40 to work, as shown in fig. 5, power supply can be realized through the charging interface 41 and the energy storage assembly 42, and the third door opening mode can realize wireless control door opening without using a key by a user.

Finally, it is necessary to explain the way of opening the door from the indoor to the outdoor, specifically, as shown in fig. 4, the lock cylinder includes an indoor unlocking assembly 30 connected with a lock shaft 36 and an electronic bolt 38, and the indoor unlocking assembly 30 is movably connected with a clutch rotating member 34. The indoor unlocking assembly 30 may be a circular twistable mechanism, and the twisting of the indoor unlocking assembly 30 may cause the electronic bolt 38 to pop out of the through hole of the lock shaft 36, so that the lock shaft 36 is unlocked, and the twisting of the indoor unlocking assembly 30 may push the clutch rotating member 34 to move backward (i.e., in a direction opposite to the forward direction mentioned above) so that the front portion of the lock cylinder (the front portion includes the knob 32, the lock cylinder 33, the clutch rotating member 34 and the pull tab 35) is connected with the lock shaft 36 and integrated into a whole, so that when a user rotates the indoor unlocking assembly 30 indoors, the lock shaft 36 and the pull tab 35 integrated therewith may be driven to rotate, so that the pull tab 35 drives the lock tongue to unlock the door, and the user opens the door indoors.

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.
