DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 2In this embodiment, a smart lock with a backup lock core includes a shell 1, a stabilizing plate 2 is fixed to the inner top wall of the shell 1, a partition 3 is fixed to the right inner wall of the shell 1, the bottom of the stabilizing plate 2 is fixed to the top of the partition 3, and a sensor 4 is fixed to the right inner wall of the shell 1. The physical isolation of the stabilizing plate 2 and the partition 3 can ensure that the sensor 4 will not be affected by other components, further increasing the service life of the sensor 4. The sensor 4 is located above the partition 3, and a power mechanism 5 for providing power for unlocking and closing the smart lock is provided on the left side of the stabilizing plate 2. A backup component 6 for improving the overall reliability of the smart lock is provided on the right inner wall of the shell 1.

[0024] It can be seen that there is a sensing area on the right side of the shell 1, and the sensing area is located in the same place as the sensor 4. This design can increase the speed of successful recognition. The sensing area is wavy as a whole, which can play a role in improvement.

[0025] In addition, the power mechanism 5 includes a stepper motor 501 fixed to the right side of the stabilizing plate 2. The output shaft of the stepper motor 501 is provided with a rotating part 502. A sliding seat 503 is fixed to the inner top wall of the outer shell 1. The inner side of the sliding seat 503 is movably connected with a rack 504. The sliding seat 503 can limit the rack 504, further improve the stability of the rack 504, and ensure that the rack 504 is smoothly locked and unlocked under the action of the driving gear 5022.

[0026] It should be further explained that the rotating part 502 includes an active rod 5021 fixed to the output shaft of the stepping motor 501. The outer surface of the active rod 5021 is fixed with a driving gear 5022 and a cylindrical gear 5023 from left to right. The cylindrical gear 5023 can transmit the power of mechanical unlocking to the active rod 5021, thereby promoting the smooth progress of mechanical unlocking.

[0027] It can be known that the cylindrical gear 5023 is engaged with the transmission gear 609, the rack 504 extends to the outside of the bottom wall of the sliding seat 503, the bottom wall of the rack 504 is engaged with the driving gear 5022, and a movable hole is opened on the rear side wall of the shell 1, and the movable hole is adapted to the rack 504. The adaptation of the movable hole and the rack 504 can ensure that the rack 504 passes through the movable hole smoothly, thereby realizing unlocking and locking.

[0028] In this embodiment, the sensor 4 can further facilitate the user to unlock the device under normal circumstances. The stepping motor 501 drives the driving gear 5022 to cause the rack 504 to extend or retract, which can effectively improve the unlocking efficiency of the device.

[0029] See also Figures 1 to 2 and Figure 3In order to improve the reliability of the device, the spare component 6 in this embodiment includes a sleeve 601 fixed to the right side wall of the shell 1 and extending to the outside of the right side wall of the shell 1. A lock core 602 is rotatably connected to the sleeve 601. A clamping hole is provided on the top of the lock core 602. A locking portion 603 is provided in the clamping hole. A stabilizing plate 604 is rotatably connected to the left side of the lock core 602 through a bearing. A plurality of spring compression blocks 605 are fixed to the left side of the stabilizing plate 604. The provision of multiple spring compression blocks 605 can assist the lock core 602 to ensure that the lock core 602 returns to its original position when no force is applied. In situ, multiple spring compression blocks 605 are fixed to the left inner wall of the sleeve 601, and a rotating rod 606 is fixed to the left side of the lock core 602, which penetrates the outside of the left side wall of the sleeve 601. The rotating rod 606 and the lock core 602 are located on the same axis. The same axis can ensure that there is no eccentricity during the rotation process, further improving the stability of the rotation of the rotating gear 607. The outer surface of the rotating rod 606 is fixed with a rotating gear 607, and the left side wall of the shell 1 is rotatably connected to the transmission rod 608 through a bearing, and the outer surface of the transmission rod 608 is fixed with a transmission gear 609.

[0030] In addition, the outer surface of the lock core 602 is movably connected with a rotating bearing, and the lock core 602 is movably connected to the rotating bearing, which can ensure the smooth movement of the lock core 602 and improve the rotation stability of the lock core 602. The lock core 602 is rotatably connected to the sleeve 601 through the rotating bearing. A keyhole is provided on the inner side of the lock core 602, and the keyhole is connected to the clamping hole. The clamping hole is stepped, and the stepped shape can provide reliable support for the locking part 603. The locking part 603 is composed of a primary clamping block 6031 and a secondary clamping block 6032. The setting of the primary clamping block 6031 and the secondary clamping block 6032 can It can improve the security of the smart lock. If a thief wants to unlock the lock mechanically, it is difficult to open the lock. The lock can only be unlocked when the first-level clamping block 6031 is just opened and the second-level clamping block 6032 is pushed out of the clamping hole. If the ejection distance is insufficient or exceeds, it cannot be unlocked smoothly. The first-level clamping block 6031 includes a compression spring fixed to the bottom wall of the clamping hole, and a connecting plate is fixed on the top of the compression spring. The bottom of the connecting plate is fixed with a spring block that passes through the clamping hole and extends into the keyhole. The second-level clamping block 6032 includes a tension spring fixed to the bottom wall of the partition 3, and the bottom of the tension spring is fixed with a limit block that is against the connecting plate.

[0031] In addition, each spring compression block 605 includes a box body 6051 fixed to the left inner wall of the sleeve 601, and an elastic spring 6052 is fixed to the left inner wall of the box body 6051. A telescopic block 6053 is fixed to the end of the elastic spring 6052 away from the box body 6051, and the right side of the telescopic block 6053 is fixed to the stabilizing plate 604. The elastic spring 6052 can smoothly pop out the telescopic block 6053, further ensuring that the lock core 602 can smoothly return to its original position when not subject to external force.

[0032] It should be further explained that the lock core 602 and the right side wall of the shell 1 are located in the same plane, and the transmission gear 609 and the rotating gear 607 are staggered. Setting the transmission gear 609 and the rotating gear 607 to be staggered can ensure that when the smart lock is operating normally, power will not be transmitted to the lock core 602, further ensuring the normal operation of the device.

[0033] In this embodiment, by coordinating the spring compression block 605, the staggered arrangement of the transmission gear 609 and the rotating gear 607, and the locking portion 603, the stability of the mechanical unlocking can be ensured while the security of the smart lock can be improved. It can effectively prevent other unrelated personnel from unlocking the lock, ensuring that users can use it with confidence.

[0034] It can be understood that the smart lock can effectively improve the reliability of the smart lock by combining mechanical unlocking with electronic unlocking. At the same time, the anti-theft effect of mechanical unlocking is very good, which can provide sufficiently good protection and further increase the reliability of the smart lock.

[0035] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0036] The working principle of the above embodiment is:

[0037] (1) During normal unlocking, the IC card or the mobile phone with the NFC function turned on is placed on the sensing area. At this time, the sensor 4 will drive the stepper motor 501, which will further drive the active gear 5022 and the cylindrical gear 5023 on the active rod 5021 to rotate, and further drive the rack 504 in the sliding seat 503 to move in the housing 1, thereby completing the unlocking.

[0038] (2) When the electronic components in the smart lock fail, the exclusive key can be inserted into the keyhole, pushed inward and rotated. When the key is inserted, it will push the first-level clamping block 6031 to move upward, further driving the second-level clamping block 6032 to move upward. At this time, the second-level clamping block 6032 completely withdraws from the clamping hole, and then the driving force causes the rotating gear 607 to engage with the transmission gear 609. Finally, the rotating force causes the rotating gear 607 to drive the transmission gear 609 to rotate, further driving the cylindrical gear 5023 to rotate, and finally causing the driving gear 5022 to rotate and drive the rack 504 to retract to complete the unlocking. The device can effectively increase the reliability of the smart lock by coordinating electronic unlocking and mechanical unlocking. When the electronic unlocking fails, emergency unlocking can still be performed by mechanical unlocking.

[0039] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations.
