[0033] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be understood as limiting the scope of protection of the present invention.

[0034] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0035] Reference Figure 1 , the present invention provides a smart lock control method:

[0036] Perform identity verification;

[0037] If the identity verification is passed, the lock cylinder 11 is unlocked, and the key 90 is inserted into the lock cylinder 11 and turned to unlock the lock;

[0038] If the identity verification fails, the lock cylinder 11 is locked, and inserting the key 90 into the lock cylinder 11 and turning it cannot unlock the lock.

[0039] When using key 90 to unlock, identity authentication is required first. Only when the identity authentication is passed can the key 90 be used to unlock. If the identity authentication fails or no identity authentication is performed, the lock cannot be unlocked directly using key 90 to prevent the lock cylinder 11 from being forcibly opened by unlocking tools. In this way, the dual protection method of key 90 and identity authentication is used to improve safety and reliability.

[0040] Identity verification can be performed by fingerprint verification, password verification or password card verification. Unlocking the lock cylinder 11 means that the shaft 12 of the lock cylinder 11 can rotate in the unlocking direction, and locking the lock cylinder 11 means that the shaft 12 of the lock cylinder 11 cannot rotate in the unlocking direction.

[0041] Under normal circumstances, the user can unlock the door after passing the identity verification without using the key 90. In unexpected circumstances, such as when the internal electric device for unlocking fails, the door cannot be unlocked even after the identity verification is passed. In this case, the user needs to use the identity verification and key 90 to manually unlock the door.

[0042] As a preferred embodiment, when the power is off, the lock cylinder 11 is automatically unlocked, and the key 90 can be inserted into the lock cylinder 11 and turned to unlock it, thereby avoiding the situation where the lock cannot be unlocked when a power outage occurs due to bad weather, emergencies, etc.

[0043] refer to Figure 1 As a preferred embodiment, when identity verification fails or no identity verification is performed, inserting an object into the lock cylinder 11 will trigger an alarm. When an attacker attempts to forcibly open the lock using a lock picking tool, the alarm will alert the owner, allowing the owner to be aware of the attack and at the same time intimidating the attacker, which is conducive to stopping the attacker's attempt to forcibly open the lock.

[0044] refer to Figure 1 In order to be able to unlock the door only by using the key 90 in an unexpected situation, when the identity authentication fails or no identity authentication is performed, the key 90 is inserted into the lock cylinder 11 and after a first preset time, the lock cylinder 11 is unlocked and maintained for a second preset time. After the second preset time, the lock cylinder 11 is locked.

[0045] In the event of an accident such as a damaged fingerprint, forgotten password, or lost password card, the owner can insert the key 90 into the lock cylinder 11 and wait for a first preset time (e.g., 15 minutes) for the lock cylinder 11 to unlock. The key 90 can then be used to unlock the lock, thereby achieving the purpose of emergency unlocking. The lock cylinder 11 remains unlocked for a second preset time (e.g., 20 seconds). After the second preset time, the lock cylinder 11 is relocked to improve security. Considering the possibility of missing the unlocking of the lock cylinder 11, after the lock cylinder 11 is relocked, the first preset time can be waited again for the lock cylinder 11 to unlock, and this process can be repeated.

[0046] refer to Figure 1 , as a preferred embodiment, including a locking mode and an unlocking mode;

[0047] In the locked mode, the lock cylinder 11 is in a locked state, and identity authentication is required and the lock cylinder 11 is unlocked after the identity authentication is passed;

[0048] In the unlocking mode, the lock cylinder 11 is always in the unlocking state.

[0049] The owner can set the working mode as the lock mode or the unlock mode according to the use requirement, and the use is more flexible and convenient. In the lock mode, the dual security protection of the identity authentication and the key 90 is provided, and in the unlock mode, the key 90 can be directly used to unlock.

[0050] Reference Figure 1 In order to further improve the flexibility of use, the authentication time range can be set, so that when the authentication time range is set, the lock mode is switched. The owner can set the authentication time range as the working time or the sleep time according to the own work and rest time, and the security can be effectively improved without causing the use trouble.

[0051] Reference Figures 2 to 5 The intelligent lock applying the intelligent lock control method comprises:

[0052] A lock body 10 and a lock core 11, the lock body 10 is connected with the lock core 11;

[0053] An electric lock mechanism 20 is arranged on the lock body 10, and the electric lock mechanism 20 can be clamped with the lock core 11 to limit the rotation of the lock core 11;

[0054] A control unit 30 is electrically connected with the electric lock mechanism 20;

[0055] An authentication unit 40 is electrically connected with the control unit 30.

[0056] The identity authentication is performed through the authentication unit 40, and the authentication result is transmitted to the control control unit 30, when the authentication result is passed, the control unit 30 controls the electric lock mechanism 20 and the lock core 11 to be unlocked, so that the key 90 can drive the lock core 11 to rotate in the unlocking direction, and the unlocking is realized; when the authentication result is not passed, the control unit 30 controls the electric lock mechanism 20 and the lock core 11 to be clamped, so that the lock core 11 cannot rotate in the unlocking direction.

[0057] Reference Figure 3The electric locking mechanism 20 can be an embodiment including an electromagnet 21, a pin 22 and a spring 23. The rotating shaft 12 of the lock cylinder 11 is provided with a bayonet 13. The control unit 30 controls the current flowing through the electromagnet 21 to increase, so that the electromagnet 21 attracts the pin 22 and squeezes the spring 23, so that the pin 22 extends into the bayonet 13 to engage with the rotating shaft 12 (or the pin 22 exits the bayonet 13 and unlocks the rotating shaft 12). The control unit 30 controls the current flowing through the electromagnet 21 to decrease, so that the adsorption force of the electromagnet 21 is weakened, and the restoring force of the spring 23 pushes the pin 22 to exit the bayonet 13 to unlock the rotating shaft 12 (or the pin 22 extends into the bayonet 13 and engages with the rotating shaft 12). In this process, the lock cylinder 11 is locked or unlocked. The electric locking mechanism 20 can also be implemented using a motor and an ejector pin 22. The rotating shaft 12 is provided with a bayonet 13. The control unit 30 controls the motor to rotate forward, causing the ejector pin 22 to extend into the bayonet 13 and engage with the rotating shaft 12. The control unit 30 controls the motor to rotate backward, causing the ejector pin 22 to exit the bayonet 13 and unlock the rotating shaft 12. The bayonet 13 on the rotating shaft 12 can be a strip-shaped opening along the circumference. When the ejector pin 22 enters the strip-shaped opening, it is located at the end of the strip-shaped opening, so that the rotating shaft 12 can only rotate in the locking direction, but not in the unlocking direction.

[0058] The control unit 30 may be a component capable of receiving, processing and sending data signals, such as a single chip microcomputer or an embedded control chip. The verification unit 40 may be implemented as a semiconductor fingerprint sensor, an optical fingerprint sensor, a password input keyboard or a card reader.

[0059] refer to Figure 2 、 Figure 3 as well as Figure 5 As a preferred embodiment, the lock system further includes a detection unit 50 and an alarm unit 60. The detection unit 50 is connected to the lock cylinder 11 to detect whether an object has been inserted into the lock cylinder 11. The control unit 30 is electrically connected to the alarm unit 60. The detection unit 50 detects whether an object has been inserted into the lock cylinder 11 and transmits the detection result to the control unit 30. When an object is detected to have been inserted into the lock cylinder 11 and the electric locking mechanism 20 is engaged with the lock cylinder 11, that is, in the locking mode, the control unit 30 controls the alarm unit 60 to operate and issue an alarm.

[0060] The detection unit 50 can be a pressure sensor, which detects whether an object is inserted by detecting the pressure on the wall of the insertion hole of the lock core 11; it can also be an infrared sensor, which determines whether an object is inserted by whether there is an object blocking it; it can also be a Hall sensor, which determines whether an object is inserted by detecting whether the ball in the lock core 11 moves.

[0061] refer to Figure 2 、 Figure 4 as well as Figure 5As a preferred embodiment, the device further includes a control unit 70 electrically connected to the control unit 30. The owner can use the control unit 70 to set the unlock mode or lock mode, or configure operating parameters such as setting a password or entering a fingerprint. The control unit 70 can be implemented in the form of a keyboard, a touch screen, or the like.

[0062] refer to Figure 2 、 Figure 4 as well as Figure 5 As a preferred embodiment, the device further includes a time unit 80 electrically connected to the control unit 30. The owner can set a verification time range for the time unit 80 via the control unit 70. At the start or end of the verification time range, the time unit 80 sends a switching signal to the control unit 30, which then changes its operating mode accordingly. The owner can also control the time unit 80 via the control unit 70 to set a first preset time and a second preset time to better meet the owner's usage needs.

[0063] The time unit 80 may be a clock chip. When the control unit 30 is a single-chip microcomputer or an embedded system chip, the time unit 80 may also be a time program in the single-chip microcomputer or the embedded system chip.

[0064] refer to Figure 4 as well as Figure 5 As a preferred embodiment, it also includes a display unit 31, and the control unit 30 is connected to the display unit 31 to control the display unit 31 to display operation prompts, time and other information.

The front panel 102, the connecting plate 103 and the lock body 10 are connected in sequence. The handle 101 passes through the front panel 102 and the connecting plate 103 to connect to the lock body 10. In the unlocked state, rotating the handle 101 can drive the internal transmission structure of the lock body 10, so that the lock tongue of the lock body 10 retracts and the door body can be pushed open. The verification unit 40 includes a semiconductor fingerprint sensor provided on the handle 101 and a keyboard connected to the front panel 102, so that the lock can be unlocked by fingerprint recognition or password input. The keyboard also serves as the control unit 70. The lock core 12 is connected to the front panel 102 and the insertion hole of the lock core 12 is located at the lower end of the front panel 102, so that the insertion position of the key 90 is concealed, which is more secure.

[0066] refer to Figure 5As another specific embodiment, the smart lock also includes a handle 101, a front panel 102 and a connecting plate 103. The connection method of the handle 101, the front panel, the connecting plate 103 and the lock body 10 is the same as that of the above embodiment and will not be repeated here. The verification unit 40 is also an embodiment that includes a semiconductor fingerprint sensor and a keyboard. The insertion hole of the lock cylinder 10 is located on the front side of the front panel 102. The front panel 102 is movably provided with a shielding plate 104. The shielding plate 104 is used to shield the insertion hole of the lock cylinder 10 to make the appearance flat and to protect the insertion hole of the lock cylinder 10 from oxidation.
