[0023] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to relevant accompanying drawings. Embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0025] It can be understood that spatial relationship terms such as "under", "below", "beneath", "underneath", "above", "over" etc. can be used herein to describe the relationship between an element or feature shown in the drawings and other elements or features. It should be understood that in addition to the orientation shown in the drawings, spatial relationship terms also include different orientations of the devices during use and operation. For example, if the device in the drawing is flipped, an element or feature described as "below other elements" or "beneath it" or "under it" will be oriented "above" other elements or features. Therefore, the exemplary terms "below" and "under" can include both the upper and lower orientations. In addition, the device can also include other orientations (such as rotating 90 degrees or other orientations), and the spatial description terms used herein are accordingly interpreted.

[0026] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediate element. In the following embodiments, "connection", if there is an electrical signal or data transfer between the connected circuits, modules, units, etc., should be understood as "electrical connection", "communication connection", etc.

[0027] As used herein, the singular forms "a", "an" and "the" may also include the plural forms unless the context clearly dictates otherwise. It should also be understood that the terms "comprising" or "having" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0028] In one embodiment, as Figure 1As shown in the figure, an intelligent recognition door lock is provided. The intelligent recognition door lock includes: an information recognition device 100, a control device 200, and a lock core 300. The information recognition device 100 is connected to the control device 200, and the control device 200 is connected to the lock core 300. The information recognition device 100 is used to collect unlocking information, compare the unlocking information with preset verification information to obtain a comparison and recognition result, and send the comparison and recognition result to the control device 200. The control device 200 is used to send a corresponding control signal to the lock core 300 according to the comparison and recognition result. The lock core 300 is used to perform corresponding unlocking actions according to the control signal.

[0029] Among them, the unlocking information includes at least one of voice information, face information, and fingerprint information. The information recognition device 100 can obtain the unlocking information in a wired or wireless manner. For example, the information recognition device 100 establishes a wireless connection with a terminal (such as the user's mobile phone) to obtain the user's fingerprint information from the user's mobile phone. Another example is that the information recognition device 100 is connected to a pickup by wire. After picking up the user's voice information through the pickup, the information recognition device 100 obtains the voice information sent by the user from the pickup. The information recognition device 100 includes an identification chip, such as a voice recognition chip. The user can independently input their own voice as the preset verification information into the voice recognition information. When the voice information is collected, the voice recognition chip will compare and recognize the voice information to obtain a comparison and recognition result, such as comparison success or comparison failure. If the voice information matches the preset verification information, it means the comparison is successful. At this time, the comparison and recognition result of successful comparison is sent to the control device 200. If the voice information does not match the preset verification information, it means the comparison is failed. At this time, the comparison and recognition result of failed comparison is sent to the control device 200.

[0030] When the control device 200 receives the comparison and recognition result of successful comparison, it sends an unlocking control signal to the lock core 300, so that the lock core 300 performs an unlocking action to open the door. When the control device 200 receives the comparison and recognition result of failed comparison, it sends a locking control signal to the lock core 300, so that the lock core 300 continues to maintain the locked state and does not open the door.

[0031] It can be understood that the preset verification information is pre-input by the user. For example, the user can pre-input voice information, fingerprint information, and face information to the information recognition device 100. After the information recognition device 100 saves the information pre-input by the user according to different types, when the unlocking information is obtained, the information recognition device 100 identifies the type of the unlocking information, and then calls the preset verification information of the corresponding type to compare with the unlocking information, so as to obtain a comparison and recognition result.

[0032] It should be noted that the lock core 300 can perform corresponding unlocking actions according to control signals. For example, a driving mechanism is provided in the lock core 300. When an unlocking control signal is received, the driving mechanism drives the lock tongue of the door lock to move to open the door. Or when the driving mechanism receives a locking control signal, the driving mechanism remains in the locked state and does not drive the lock tongue of the door lock to move, so that the door lock remains in the locked state and does not open the door.

[0033] For the above intelligent recognition door lock, the user can input one or more of voice information, face information, or fingerprint information to the information recognition device. The information recognition device recognizes the user's input information, and then the control device sends a corresponding control signal to the lock core, so that the lock core performs the corresponding unlocking action, avoiding the need for the user to carry a key when traveling, thus making it more convenient for the user to use.

[0034] Further, in one embodiment, as Figure 2 shown, the information recognition device includes a voice recognition device 110, a face recognition device 120, and a fingerprint recognition device 130. The voice recognition device 110, the face recognition device 120, and the fingerprint recognition device 130 are all connected to the control device 200.

[0035] Among them, the unlocking information includes at least one of voice information, face information, and fingerprint information. When the unlocking information is voice information, the voice recognition device 110 obtains the voice information, and then performs voice recognition according to the preset verification information to obtain a comparison recognition result. When the unlocking information is face information, the face recognition device 120 obtains the face information and performs face recognition according to the preset verification information to obtain a comparison recognition result. When the unlocking information is fingerprint information, the fingerprint recognition device 130 obtains the fingerprint information, and then performs fingerprint recognition according to the preset verification information to obtain a comparison recognition result.

[0036] It can be understood that the voice recognition device 110 may include a microphone and a voice recognition chip. The voice information is acquired through the microphone, and then the voice recognition is performed by the voice recognition chip. Correspondingly, the face recognition device 120 may include a camera and a face recognition chip, and the fingerprint recognition device 130 may include an optical fingerprint module and a fingerprint recognition chip. When the user opens the door, at least one of voice information, face information, and fingerprint information can be input. For example, when the unlocking information input by the user when opening the door is voice information, the microphone starts to work for voice pickup. When the unlocking information input by the user is face information, the camera starts to work for face information collection. When the unlocking information input by the user is fingerprint information, the optical fingerprint module starts to work for fingerprint information collection. Further, in other embodiments, the user can set that the unlocking information needs to include at least two of voice information, face information, and fingerprint information, so as to increase multi-factor authentication and effectively improve the security of the intelligent recognition door lock.

[0037] Further, in one embodiment, the voice recognition device 110 includes a voice pickup component and a comparison and recognition component. The voice pickup component is connected to the comparison and recognition component, and the comparison and recognition component is connected to the control device. Among them, the voice pickup component can be a microphone, etc., and the comparison and recognition component can be a voice recognition chip. When the user needs to open the door by voice, the user inputs his own voice as the unlocking information. After the voice pickup component collects the voice input by the user, the comparison and recognition component is used to compare the voice input by the user with the preset verification information to obtain a comparison and recognition result.

[0038] Further, in one embodiment, the voice recognition device 110 further includes a voice / digital conversion component. The voice pickup component is connected to the comparison and recognition component through the voice / digital conversion component. Among them, the voice / digital conversion component can perform digital conversion on the voice information. For example, when the user inputs voice information as the unlocking information, if the voice information contains the voice of "1", the voice / digital conversion component will convert the voice of "1" into the number 1 represented by digits, and then send the number 1 represented by digits to the comparison and recognition component. The comparison and recognition component will perform comparison and recognition according to the preset verification information to obtain a comparison and recognition result.

[0039] It can be understood that after the voice / digital conversion component converts the voice "1" into the number "1", the number "1" is compared with the preset verification information. At this time, the corresponding preset verification information is also a number, so that the comparison can be performed. By converting the voice information into a number by the voice / digital conversion component, it is convenient for subsequent comparison, and it is not necessary to use a voice recognition chip for voice recognition, which improves the recognition accuracy.

[0040] In one embodiment, the door lock further includes a locking tongue, and the lock core is connected to the locking tongue. The door lock device is provided on the door leaf, and a corresponding limiting mechanism is provided in the door frame. When closing the door, the locking tongue will snap into the limiting mechanism of the door frame, so that the door leaf is closed to the door frame. When opening the door, the lock core needs to drive the locking tongue to extend and retract from the limiting mechanism, so that the door leaf is separated from the door frame to achieve door opening. Specifically, the lock core may include a corresponding driving device, and the driving device can drive the locking tongue to extend and retract from the limiting mechanism.

[0041] In one embodiment, as Figure 3 shown, the lock core includes a housing 39, a lock cylinder 33, a clutch rotating member 34, a shifting lever 35, a lock shaft 36, and an electronic bolt 38. The lock cylinder 33, the clutch rotating member 34, the shifting lever 35, and the lock shaft 36 are axially arranged in the housing 39 in sequence. The lock cylinder 33 is connected to the shifting lever 35, and the lock cylinder 33 and the shifting lever 35 are movably connected to the lock shaft 36 through the clutch rotating member 34. The shifting lever 35 is movably connected to the locking tongue. The electronic bolt 38 is connected to the control device. The lock shaft 36 is provided with a through hole, and the electronic bolt 38 is used to insert into the through hole according to a control signal to lock the lock shaft 36 or the electronic bolt 38 pops out of the through hole according to the control signal to unlock the lock shaft 36.

[0042] Among them, the housing 39 covers other parts of the lock core inside it, playing a role in protecting other parts of the lock core. It can be understood that according to the door opening direction, the lock core can be divided into one end close to the outside of the door (the user can insert the key from this end to open the door and enter the room) and one end close to the inside of the door (the user operates to open the door from this end and enter the outside). In the order from the outside end of the door to the inside end of the door, the lock cylinder 33, the clutch rotating member 34, the shifting lever 35, the lock shaft 36, and the electronic bolt 38 are axially arranged in the housing 39 in sequence. The lock cylinder 33 and the shifting lever 35 are movably connected to the lock shaft 36 through the clutch rotating member 34. The lock cylinder 33 and the shifting lever 35 are movably connected to the lock shaft 36 through the clutch rotating member 34, that is, the clutch rotating member 34 can move. When the clutch rotating member 34 moves forward, it will cause the lock cylinder 33 and the shifting lever 35 to separate from the lock shaft 36. When the clutch rotating member 34 does not move forward, the lock cylinder 33, the shifting lever 35, and the lock shaft 36 are integrated. Specifically, when there is no key 31 inserted into the lock core, the clutch rotating member 34 integrates the lock cylinder 33 and the lock shaft 36. At this time, the lock cylinder 33, the clutch rotating member 34, the shifting lever 35, and the lock shaft 36 can be regarded as a whole. If the lock cylinder 33 rotates, the corresponding other parts will rotate. When the key 31 is inserted and rotated in the lock core, the key 31 will push the clutch rotating member 34 to move forward in the indoor direction, and the clutch rotating member 34 will push the lock shaft 36 to separate from other parts (that is, separate from the lock cylinder 33, the clutch rotating member 34, and the shifting lever 35).

[0043] When a key 31 is inserted into and rotated in the lock core, the key 31 will push the clutch rotating part 34 to move forward in the indoor direction. The clutch rotating part 34 pushes the lock shaft 36 to separate from other parts (i.e., separate from the lock cylinder 33, the clutch rotating part 34, and the shifting lever 35), causing the shifting lever 35 to rotate, thereby driving the locking tongue to move and realizing door opening. The method of inserting the key 31 to open the door is a conventional door opening method, which will not be elaborated in this embodiment. Further, in this embodiment, the door can also be opened by controlling the electronic bolt 38, that is, another door opening method. Specifically, the electronic bolt 38 is connected to the control device. When the comparison and recognition result is successful, the control device sends an unlocking control signal to the electronic bolt 38. At this time, the electronic bolt 38 pops out the through hole, unlocking the lock shaft 36. At this time, the lock shaft 36 can rotate, that is, the user can, without inserting the key, drive the lock cylinder 33 and the shifting lever 35 by rotating the knob 32, and then the shifting lever 35 drives the locking tongue to extend and retract from the limiting mechanism, thus realizing door opening. This is because when the key 31 is not inserted, the clutch rotating part 34 does not move forward, and the clutch rotating part 34, the lock cylinder 33, the shifting lever 35, and the lock shaft 36 are integrated. Since the lock shaft 36 has been unlocked, any one of the integrated clutch rotating part 34, lock cylinder 33, shifting lever 35, and lock shaft 36 can rotate. For example, rotating the lock cylinder 33 can drive other parts, causing the shifting lever 35 integrated with other parts to rotate, thereby driving the shifting lever 35 to drive the locking tongue to act and realizing door opening.

[0044] It should be noted that the lock cylinder 33 has blades inside. When the inserted key 31 matches the blades inside the lock cylinder 33, the key 31 can rotate to push the clutch rotating part 34 forward so that the clutch rotating part 34 pushes the lock shaft 36 to separate from other parts.

[0045] Further, as Figure 3 shown, the lock core further includes an indoor unlocking assembly 30. The indoor unlocking assembly 30 is connected to the lock shaft 36 and the electronic bolt 38, and the indoor unlocking assembly 30 is movably connected to the clutch rotating part 34. Among them, the indoor unlocking assembly 30 can be a circular twistable mechanism. Twisting the indoor unlocking assembly 30 can cause the electronic bolt 38 to pop out of the through hole of the lock shaft 36, unlocking the lock shaft 36, and the indoor unlocking assembly 30 will push the clutch rotating part 34 to move backward (i.e., in the opposite direction to the forward movement mentioned above) so that the front part of the lock core (the front part includes the knob 32, the lock cylinder 33, the clutch rotating part 34, and the shifting lever 35) is connected to the lock shaft 36 and integrated. Thus, when the user rotates the indoor unlocking key 30 indoors, it can drive the lock shaft 36 and the shifting lever 35 integrated with it to rotate, thereby driving the shifting lever 35 to drive the locking tongue to unlock and realizing door opening.

[0046] In one embodiment, as Figure 3As shown, the lock core includes an antenna assembly 40, and the antenna assembly 40 is connected to the control device.

[0047] The antenna assembly 40 is used to obtain an unlock signal or a lock signal and send it to the control device. The control device is used to control the electronic plug 38 to be inserted into the through hole or pop out of the through hole according to the unlock signal or the lock signal. The user can communicate data with the antenna assembly 40 through a terminal such as a mobile phone, send an unlock signal or a lock signal to the antenna assembly 40, and the antenna assembly 40 forwards the unlock signal or the lock signal to the control device. Then the control device can control the electronic plug 38 to be inserted into the through hole or pop out of the through hole according to the unlock signal or the lock signal, so that the user can perform wireless unlocking.

[0048] The antenna component 40 can be a Bluetooth communication component. For example, the user uses the Bluetooth function of the mobile phone to communicate with the Bluetooth communication component of the lock core. The user installs the corresponding unlocking software on the mobile phone, then opens the unlocking software and issues an unlocking command. After the Bluetooth communication component of the lock core receives the unlocking command, it recognizes that the unlocking command is an unlocking signal and sends the unlocking signal to the control device. The control device then controls the electronic latch 38 to pop out of the through hole to release the lock shaft 36. At this time, the user can directly rotate the knob 32 to drive the lock core 33, the clutch rotating part 34, the puller 35 and the lock shaft 36 to rotate, so that the puller 35 drives the lock tongue to unlock.

[0049] Furthermore, in another embodiment, the antenna component 40 can also be a wireless routing communication component, which is connected to the wireless network, and the user's mobile phone is also connected to the wireless network. At this time, the user can directly issue an unlocking command by operating the corresponding unlocking software installed on the mobile phone, and transmit the unlocking command to the wireless routing communication component of the lock core through the wireless network. The wireless routing communication component of the lock core sends the unlocking signal to the control device, and the control device controls the electronic latch 38 to pop out of the through hole to release the lock shaft 36. At this time, the user can directly rotate the knob 32 to drive the lock core 33, the clutch rotating part 34, the puller 35 and the lock shaft 36 to rotate, so that the puller 35 drives the lock tongue to unlock.

[0050] Furthermore, in one embodiment, the lock core further includes a camera assembly and a speaker, and both the camera assembly and the speaker are connected to the control device. The camera assembly can take pictures, and when the user is unlocking the door, for example, when the user inserts a key to unlock the door or when the electronic latch pops out of the through hole after receiving a control signal, the camera assembly can start to take pictures and collect image data of the surrounding environment of the door lock. The speaker can output voice information, such as voice information such as "unlocking success" or "unlocking failure".

[0051] In one embodiment, the lock cylinder further includes an energy storage component and a charging interface. The charging interface is connected to the energy storage component, and the energy storage component is connected to the control device. The energy storage component can be a lithium battery, a super capacitor, etc. The charging interface is a USB charging interface. When the user uses it, the energy storage component can be charged through the charging interface, and then the energy storage component supplies power to the control device. Correspondingly, the energy storage component can also supply power to other devices through the control device.

[0052] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0053] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
