These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

Example one

The embodiment provides an unlocking method and a mechanical intelligent lock system for executing the unlocking method. It should be noted that the mechanical intelligent lock system of the present invention may be used in a door lock or a cabinet lock, and the present embodiment does not limit this.

Referring to fig. 1, the mechanical smart lock system includes a key cylinder 2 and a key 1. Referring to fig. 2, the key cylinder 2 is provided with a keyhole 201, a plurality of lock tongues 202 and a cylinder side chip 203, and the cylinder side chip 203 stores cylinder side pairing information.

Referring to fig. 3, the key 1 is provided with a body 101, a plurality of key teeth 102 movably arranged on the body 101, and a key side chip 103 fixedly arranged on the body 101, wherein key side pairing information is stored in the actually measured chip. The key 1 is used for being inserted into the keyhole 201 and being in communication connection with the lock cylinder 2, and if the key side pairing information carried by the key 1 is matched with the cylinder side pairing information of the lock cylinder 2, the key teeth 102 on the key 1 move to a position matched with the lock tongue 202 of the lock cylinder 2, so that the lock cylinder 2 is opened.

Optionally, matched key side pairing information can be implanted into the key 1 according to the core side pairing information of the lock core 2 before leaving a factory, and a user can directly use the mechanical intelligent lock system without any setting after purchasing the mechanical intelligent lock system. Certainly, a pairing function can also be configured on the lock cylinder 2, a user can activate the pairing function on the lock cylinder 2, then the key 1 is connected with the lock cylinder 2, and the lock cylinder 2 writes matched key-side pairing information into the key 1.

In this embodiment, the key 1 and the lock cylinder 2 are connected through a connector assembly, for example, a connector female head 401 is arranged on an end surface of the key 1, a connector male head 402 is arranged at a bottom of the lock cylinder 2, and after the key 1 is inserted into the lock cylinder 2, the connector female head 401 and the connector male head 402 are plugged, so that the communication connection between the key 1 and the lock cylinder 2 can be realized. In some other embodiments, the key 1 may also be connected to the lock cylinder 2 in wireless communication.

In this embodiment, the body 101 is provided with a plurality of tooth storage spaces 1011 corresponding to the key teeth 102 one by one, each tooth storage space 1011 can accommodate one key tooth 102, and the tooth storage space 1011 is provided with an opening. The key 1 comprises a plurality of linear driving mechanisms 104 which correspond to the key teeth 102 one by one, and each linear driving mechanism 104 is connected with one key tooth 102 and is used for driving the key tooth 102 to extend out of the tooth storage space 1011 through the opening of the tooth storage space 1011 so as to open the lock cylinder 2.

Specifically, in the non-unlocking state, each linear driving mechanism 104 is in a retraction state, all the key teeth 102 are retracted and stored in the corresponding tooth storage spaces 1011, and the whole key 1 is in a rectangular shape, neat and beautiful in appearance and convenient to store. When the lock needs to be unlocked, the body 101 is inserted into the keyhole 201, and then the key-side chip 103 drives the linear driving mechanism 104 corresponding to each bolt 202 to work, so that the key teeth 102 corresponding to each bolt 202 can be pushed out, and the lock core 2 is opened.

In this embodiment, the linear driving mechanism 104 includes a memory alloy 1041 and a heating body 1042. The memory alloy 1041 is connected with the corresponding spoon tooth 102; when the memory alloy 1041 is in a natural state, the memory alloy 1041 is in a retraction state, and the corresponding spoon tooth 102 is driven to retract into the tooth storage space 1011. The heating body 1042 can be a resistance wire electrically connected with the spoon-side chip 103, and the heating body 1042 is in contact connection with the memory alloy 1041; when the heating body 1042 works, the memory alloy 1041 is heated to be deformed by outward expansion, so that the corresponding key tooth 102 extends out of the tooth storage space 1011 to open the lock cylinder 2. It can be understood that, when unlocking, only the heating body 1042 corresponding to the key tooth 102 that needs to be extended is powered, and the heating body 1042 corresponding to the key tooth 102 that does not need to be extended is not powered, so that independent telescopic control of each key tooth 102 can be realized. Of course, in some other embodiments, the linear driving mechanism 104 may also be a micro motor or an electromagnet, and the invention is not limited thereto.

Referring to fig. 4, a position-locking boss 1012 perpendicular to the telescopic direction of the key teeth 102 is arranged at the opening of the tooth storage space 1011; the key tooth 102 is provided with a slot 1021 which is clamped with the clamping boss 1012, when the linear driving mechanism 104 pushes out the key tooth 102, the clamping boss 1012 can be clamped into the slot 1021, so that the problem that the key tooth 102 is easily retracted in the unlocking process to cause unlocking failure is avoided, and the smoothness in unlocking is improved.

Referring to fig. 5, when the mechanical smart lock provided in this embodiment is used to execute the unlocking method provided in this embodiment, the unlocking method includes the following steps:

s101: inserting a key 1 into a keyhole 201 of a lock cylinder 2 to enable the key 1 to be in communication connection with the lock cylinder 2; wherein, the key 1 is provided with a plurality of movably arranged key teeth 102;

s102: if the key side pairing information carried by the key 1 matches the core side pairing information stored in the lock core 2, the key teeth 102 on the key 1 move to positions matching the lock tongues 202 of the lock core 2, so that the lock core 2 is opened.

In this embodiment, the unlocking manner of each bolt 202 of the lock cylinder 2 is fixed, but each key tooth 102 in the key 1 is movably arranged, after the key 1 is inserted into the lock cylinder 2, the lock cylinder 2 needs to establish communication connection with the key 1, and reads key-side pairing information in the key 1, if the key-side pairing information carried by the key 1 matches with the core-side pairing information stored in the lock cylinder 2, the lock cylinder 2 sends position information of each key tooth 102 needing to be extended to the key 1 according to the position of each bolt 202, and the key 1 drives the corresponding key tooth 102 to be extended according to each position information, so as to open the lock cylinder 2.

For example, referring to fig. 6, the key 1 includes ten key bits arranged in two upper and lower rows, the upper row being sequentially designated as an upper one-tooth 102a, an upper two-tooth 102b, an upper three-tooth 102c, an upper four-tooth 102d and an upper five-tooth 102e from left to right, and the lower row being sequentially designated as a lower one-tooth 102f, a lower one-tooth 102g, a lower three-tooth 102h, a lower four-tooth 102 and a lower five-tooth 102j from left to right. Referring to fig. 7, the lock cylinder 2 includes ten lock tongues, which are arranged in two rows, an upper row is sequentially marked as an upper first tongue 202a, an upper second tongue 202b, an upper third tongue 202c, an upper fourth tongue 202d, and an upper fifth tongue 202e from left to right, a lower row is sequentially marked as a lower first tongue 202f, a lower second tongue 202g, a lower third tongue 202h, a lower fourth tongue 202i, and a lower fifth tongue 202j from left to right, and when the upper first tongue 202a, the upper third tongue 202c, the lower second tongue 202g, and the lower fifth tongue 202j are simultaneously pushed away, the lock cylinder 2 is opened.

As shown in fig. 8, after the key 1 is inserted into the keyhole 201, when the key-side pairing information carried by the key 1 matches the core-side pairing information stored in the key cylinder 2, the key cylinder 2 sends the position information of the upper one, the upper three, the lower two and the lower five to the key 1, and then the key 1 extends the upper one tooth 102a, the upper three teeth 102c, the lower two teeth 102g and the lower five teeth 102j, so that the upper one tongue 202a, the upper three tongues 202c, the lower two tongues 202g and the lower five tongues 202j are simultaneously pushed away, and the key cylinder 2 can be opened.

It can be understood that if the key side pairing information carried by the key 1 does not match the core side pairing information stored in the key cylinder 2, the key cylinder 2 does not send position information to the key 1, and the key 1 cannot unlock the key cylinder 2. Optionally, for theft prevention, the following settings may be performed: within a preset time limit, if the lock cylinder 2 continuously monitors illegal access of the key 1 for a preset number of times, an alarm sound can be automatically sent out or the alarm system 3 can be automatically triggered at the background to contact security personnel or a homeowner to check the situation. For example, three operations of inserting the key 1 are continuously detected within three minutes, but the key-side pairing information is wrong, the lock cylinder 2 can automatically give an alarm or automatically trigger the alarm system 3 in the background to contact security personnel or a homeowner to check the situation.

It should be noted that, as long as key side pairing information matched with the plurality of lock cylinders 2 is configured in the key 1 in advance, unlocking of the plurality of lock cylinders 2 can be realized by using one key 1, for example:

when the key 1 is inserted into the first lock cylinder, the first key side pairing information in the key 1 is matched with the first core side pairing information stored in the first lock cylinder, the first lock cylinder sends the position information of the first upper tooth, the first lower tooth and the first lower tooth to the key 1, and then the key 1 enables the first upper tooth, the first upper three teeth, the second lower teeth and the first lower teeth to extend out, so that the first lock cylinder can be opened;

when the key 1 is inserted into the second lock cylinder, the second key side pairing information in the key 1 is matched with the second cylinder side pairing information stored in the second lock cylinder, the second lock cylinder sends the position information of the upper two, the upper five, the lower one and the lower four to the key 1, and then the key 1 enables the upper two teeth, the upper five teeth, the lower one teeth and the lower four teeth to extend out, so that the second lock cylinder can be opened.

It should be noted that, in some other embodiments, one key tooth may correspond to two, three or even more lock tongues, and the invention is not limited thereto.

According to the unlocking method provided by the embodiment, on one hand, each key tooth 102 in the key 1 is movably arranged, and the unlocking operation of a plurality of lock cylinders 2 can be realized by using one key 1, so that the problem that the inconvenience caused by carrying a plurality of keys 1 in the traditional mechanical lock is effectively solved; on the other hand, as long as implant corresponding key side pairing information in advance in key 1, follow-up unblanking operation is exactly to insert key 1 in the keyhole 201 of lock core 2, then opens lock core 2, and the experience of whole process is similar with traditional mechanical key 1, need not to carry out password or fingerprint and enters the operation, and the learning cost is lower, and middle-aged and old people also can easily master, the facilitate promotion.

When the lock needs to be unlocked, the body 101 is inserted into the keyhole 201, and then the key-side chip 103 drives the linear driving mechanism 104 corresponding to each bolt 202 to work, so that the key teeth 102 corresponding to each bolt 202 can be pushed out, and the lock core 2 is opened.

In this embodiment, the linear driving mechanism 104 includes a memory alloy 1041 and a heating body 1042. The memory alloy 1041 is connected with the corresponding spoon tooth 102; when the memory alloy 1041 is in a natural state, the memory alloy 1041 is in a retraction state, and the corresponding spoon tooth 102 is driven to retract into the tooth storage space 1011. The heating body 1042 can be a resistance wire electrically connected with the spoon-side chip 103, and the heating body 1042 is in contact connection with the memory alloy 1041; when the heating body 1042 works, the memory alloy 1041 is heated to be deformed by outward expansion, so that the corresponding key tooth 102 extends out of the tooth storage space 1011 to open the lock cylinder 2. It can be understood that, when unlocking, only the heating body 1042 corresponding to the key tooth 102 that needs to be extended is powered, and the heating body 1042 corresponding to the key tooth 102 that does not need to be extended is not powered, so that independent telescopic control of each key tooth 102 can be realized. Of course, in some other embodiments, the linear driving mechanism 104 may also be a micro motor, and the invention is not limited thereto.

Referring to fig. 4, a position-locking boss 1012 perpendicular to the telescopic direction of the key teeth 102 is arranged at the opening of the tooth storage space 1011; the key tooth 102 is provided with a slot 1021 which is clamped with the clamping boss 1012, when the linear driving mechanism 104 pushes out the key tooth 102, the clamping boss 1012 can be clamped into the slot 1021, so that the problem that the key tooth 102 is easily retracted in the unlocking process to cause unlocking failure is avoided, and the smoothness in unlocking is improved.

Referring to fig. 11, when the mechanical smart lock provided in this embodiment is used to execute the unlocking method provided in this embodiment, the unlocking method includes the following steps:

s201: the terminal 5 is in communication connection with the lock cylinder 2 and acquires the cylinder side pairing information of the lock cylinder 2;

s202: the terminal 5 is in communication connection with the key 1 and writes key side pairing information matched with the core side pairing information into the key 1;

s203: inserting a key 1 into a keyhole 201 of a lock cylinder 2 to enable the key 1 to be in communication connection with the lock cylinder 2; wherein, the key 1 is provided with a plurality of movably arranged key teeth 102;

s204: if the key side pairing information carried by the key 1 matches the core side pairing information stored in the lock core 2, the key teeth 102 on the key 1 move to positions matching the lock tongues 202 of the lock core 2, so that the lock core 2 is opened.

In this embodiment, the unlocking manner of each bolt 202 of the lock cylinder 2 is fixed, but each key tooth 102 in the key 1 is movably arranged, after the key 1 is inserted into the lock cylinder 2, the lock cylinder 2 needs to establish communication connection with the key 1, and reads key-side pairing information in the key 1, if the key-side pairing information carried by the key 1 matches with the core-side pairing information stored in the lock cylinder 2, the lock cylinder 2 sends position information of each key tooth 102 needing to be extended to the key 1 according to the position of each bolt 202, and the key 1 drives the corresponding key tooth 102 to be extended according to each position information, so as to open the lock cylinder 2.

For example, referring to fig. 6, the key 1 includes ten key bits arranged in two upper and lower rows, the upper row being sequentially designated as an upper one-tooth 102a, an upper two-tooth 102b, an upper three-tooth 102c, an upper four-tooth 102d and an upper five-tooth 102e from left to right, and the lower row being sequentially designated as a lower one-tooth 102f, a lower one-tooth 102g, a lower three-tooth 102h, a lower four-tooth 102 and a lower five-tooth 102j from left to right. Referring to fig. 7, the lock cylinder 2 includes ten lock tongues, which are arranged in two rows, an upper row is sequentially marked as an upper first tongue 202a, an upper second tongue 202b, an upper third tongue 202c, an upper fourth tongue 202d, and an upper fifth tongue 202e from left to right, a lower row is sequentially marked as a lower first tongue 202f, a lower second tongue 202g, a lower third tongue 202h, a lower fourth tongue 202i, and a lower fifth tongue 202j from left to right, and when the upper first tongue 202a, the upper third tongue 202c, the lower second tongue 202g, and the lower fifth tongue 202j are simultaneously pushed away, the lock cylinder 2 is opened.

As shown in fig. 8, after the key 1 is inserted into the keyhole 201, when the key-side pairing information carried by the key 1 matches the core-side pairing information stored in the key cylinder 2, the key cylinder 2 sends the position information of the upper one, the upper three, the lower two and the lower five to the key 1, and then the key 1 extends the upper one tooth 102a, the upper three teeth 102c, the lower two teeth 102g and the lower five teeth 102j, so that the upper one tongue 202a, the upper three tongues 202c, the lower two tongues 202g and the lower five tongues 202j are simultaneously pushed away, and the key cylinder 2 can be opened.

It can be understood that if the key side pairing information carried by the key 1 does not match the core side pairing information stored in the key cylinder 2, the key cylinder 2 does not send position information to the key 1, and the key 1 cannot unlock the key cylinder 2. Optionally, for theft prevention, the following settings may be performed: within a preset time limit, if the lock cylinder 2 continuously monitors illegal access of the key 1 for a preset number of times, an alarm sound can be automatically sent out or the alarm system 3 at the cloud end can be automatically triggered at the background, so that security personnel or a homeowner can be contacted to check the situation.

It should be noted that, as long as key side pairing information matched with the plurality of lock cylinders 2 is configured in the key 1 in advance, unlocking of the plurality of lock cylinders 2 can be realized by using one key 1, for example:

when the key 1 is inserted into the first lock cylinder, the first key side pairing information in the key 1 is matched with the first core side pairing information stored in the first lock cylinder, the first lock cylinder sends the position information of the first upper tooth, the first lower tooth and the first lower tooth to the key 1, and then the key 1 enables the first upper tooth, the first upper three teeth, the second lower teeth and the first lower teeth to extend out, so that the first lock cylinder can be opened;

when the key 1 is inserted into the second lock cylinder, the second key side pairing information in the key 1 is matched with the second cylinder side pairing information stored in the second lock cylinder, the second lock cylinder sends the position information of the upper two, the upper five, the lower one and the lower four to the key 1, and then the key 1 enables the upper two teeth, the upper five teeth, the lower one teeth and the lower four teeth to extend out, so that the second lock cylinder can be opened.

In this embodiment, the terminal 5 acquires the core-side pairing information after being in communication connection with the lock cylinder 2, and then implants the key-side pairing information into the key 1 according to the core-side pairing information, so that the key 1 can be successfully paired with the lock cylinder 2. This greatly facilitates the reuse of the key 1. For example, the terminal 5 is made to establish communication connection with a plurality of lock cylinders 2 in advance and obtain the cylinder side pairing information of each lock cylinder 2, then when a subsequent user holds the terminal 5 and approaches different lock cylinders 2, the terminal 5 immediately writes corresponding key side pairing information into the key 1, and the key 1 can open the lock cylinders 2, that is, all the lock cylinders 2 which have been verified with the terminal 5 can be opened by holding the terminal 5 and one key 1, so that one key is multipurpose.

Alternatively, it may be set in the APP, and after every predetermined time, for example, 1 min or 3 min, the writing function of the key 1 is disabled, and after disabling the writing function, even if the key 1 is inserted into the key cylinder 2, the position information of the key teeth 102 that need to be extended and are transmitted from the key cylinder 2 cannot be received, so that the key cylinder 2 cannot be opened. Such an arrangement may prevent theft after the key 1 is picked up by others. Correspondingly, before unlocking every time, the information such as the password, the fingerprint or the iris and the like needs to be verified in the terminal 5, the verification is successful, it is indicated that the current user is the owner of the terminal 5, the terminal 5 can temporarily activate the writing function of the key 1, at this time, the key 1 can be pulled out from the accommodating groove 501, then the key 1 is inserted into the lock cylinder 2, and the key 1 can normally receive the position information of the key teeth 102 needing to be extended, sent from the lock cylinder 2, and further normally open the lock cylinder 2. After the unlocking is finished and the designated time is passed, the writing function of the key 1 can be forbidden again, so that the anti-theft performance of the mechanical intelligent lock system is improved.

Further, in order to improve the convenience of unlocking, the verification process can be set as a screen unlocking process, that is, as long as the user of the terminal 5 performs the screen unlocking operation through the password, the fingerprint, the face recognition and other biometric information, the terminal 5 automatically activates the writing function of the key 1 without performing the operation in the designated APP.

It should be noted that, in some other embodiments, one key tooth may correspond to two, three or even more lock tongues, and the invention is not limited thereto.

According to the unlocking method provided by the embodiment, on one hand, the key can be accommodated in the terminal, and the portability is good; on the other hand, the writing function of the key can be activated only by completing identity information verification, the triple protection effects of mechanical triggering, pairing information verification and terminal verification are achieved, the burglary event caused by the fact that other people pick up the key is effectively prevented, and the anti-theft performance of the mechanical intelligent lock system is greatly improved.
