Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to an NFC smart lock. Background Technology

[0002] Currently, with the continuous development of locks, users' requirements for lock security are also gradually increasing. Traditional smart locks and mechanical locks usually adopt a one-way locking method, that is, existing locks include a lock body and a shackle. When one end of the shackle is inserted into the interior and the other end is inserted into the lock body, the locking element inside the lock body will lock that end. This locking method is relatively easy to open, resulting in low security. Consequently, traditional smart locks and mechanical locks are gradually becoming unable to meet users' requirements for lock security. Utility Model Content

[0003] The main purpose of this invention is to propose an NFC smart lock, which aims to solve the technical problem of how to improve the security of existing locks.

[0004] To achieve the above objectives, the NFC smart lock proposed in this utility model includes:

[0005] Lock body;

[0006] The shackle includes a first insertion section, a second insertion section, and a connecting section connecting the first insertion section and the second insertion section. The lock body has a slot and a groove. The second insertion section slides against the wall of the groove. The second insertion section includes a locked position and an unlocked position. The second insertion section can reciprocate between the locked position and the unlocked position. When the second insertion section is in the locked position, the first insertion section is inserted into the slot. When the second insertion section is in the unlocked position, the first insertion section is disengaged from the slot.

[0007] A locking mechanism includes a first locking component and a second locking component. The lock body has an internal receiving cavity communicating with the slide groove and the slot. The first locking component and the second locking component are located within the receiving cavity. The first locking component includes a first driving member and a first locking member connected by a transmission connection. The second locking component includes a second driving member and a second locking member connected by a transmission connection. When the second insertion segment is in the locked position, the first driving member can drive the first locking member to engage with the first insertion segment, and the second driving member can drive the second locking member to engage with the second insertion segment, thereby restricting the second insertion segment from leaving the locked position.

[0008] The control module is communicatively connected to both the first driving component and the second driving component. The control module is also communicatively connected to a mobile terminal. The control module is used to control the first driving component to move the first locking component and to control the second driving component to move the second locking component.

[0009] In one embodiment, the first locking assembly further includes a first guide member, which and the first driving member are both fixedly connected to the lock body, and the first guide member is slidably engaged with the first locking member; the second locking assembly further includes a second guide member, which and the second driving member are both fixedly connected to the lock body, and the second guide member is slidably engaged with the second locking member.

[0010] In one embodiment, the first guide member is provided with a first sliding groove, and the first locking member includes a first locking part and a first slider connected to each other. The first sliding groove is slidably engaged with the first slider, and the first locking part is throttle-connected to the first driving member. The first driving member is used to drive the first locking member to engage or disengage with the first insertion segment. The second guide member is provided with a second sliding groove, and the second locking member includes a second locking part and a second slider connected to each other. The second sliding groove is slidably engaged with the second slider, and the second locking part is throttle-connected to the second driving member. The second driving member is used to drive the second locking member to engage or disengage with the second insertion segment.

[0011] In one embodiment, the first insertion segment has a first slot, and the first driving member is used to drive the first locking member to insert into or disengage from the first slot; the second insertion segment has a second slot, and the second driving member is used to drive the second locking member to insert into or disengage from the second slot.

[0012] In one embodiment, the groove includes a through hole and a mounting cavity that are interconnected. The inner diameter of the mounting cavity is larger than the inner diameter of the through hole. The second insertion section includes a body portion and a limiting portion that are interconnected. One end of the body portion away from the limiting portion is connected to the connecting section. The limiting portion is located inside the mounting cavity, and the outer diameter of the limiting portion is larger than the inner diameter of the through hole. The limiting portion slides against the cavity wall of the mounting cavity, and the body portion slides against the hole wall of the through hole.

[0013] In one embodiment, the NFC smart lock further includes an elastic element located within the mounting cavity. One end of the elastic element is connected to the limiting portion, and the other end of the elastic element is connected to the bottom wall of the mounting cavity. The elastic element is used to drive the second insertion segment to move from the locked position to the unlocked position.

[0014] In one embodiment, the control module includes a control module and an NFC sensing module that are connected in communication. The NFC sensing module is disposed on the lock body. The first driving member and the second driving member are both connected in communication with the control module. The NFC sensing module can also be connected in communication with the mobile terminal. The control module is used to control the first driving member to drive the first locking member to move and to control the second driving member to drive the second locking member to move.

[0015] In one embodiment, the NFC smart lock further includes a smart lock system, which includes a database module, an access control module, and a lock information module that are interconnected. The lock information module is also used to communicate with the mobile terminal.

[0016] In one embodiment, the NFC smart lock further includes an electronic key and a reader. The lock body has a cavity inside to accommodate the reader, and the lock body has an insertion hole outside for inserting the electronic key. The insertion hole communicates with the cavity, and the reader is communicatively connected to the control module. The reader is used to detect whether the electronic key is inserted into the insertion hole.

[0017] In one embodiment, the NFC smart lock further includes a resilient anti-collision block, which is sleeved around the periphery of the connecting segment;

[0018] And / or, the NFC smart lock further includes a guide member, the guide member having a guide hole, the guide member being connected to the lock body, the guide hole being oriented toward the slot and communicating with the slot; the diameter of the guide hole is gradually widened along the extension direction of the slot toward the direction away from the slot.

[0019] The technical solution of this utility model, when the second insertion segment is in the locked position, drives the first locking member, which is connected to it, to engage with the first insertion segment, thereby locking the first insertion segment; and drives the second locking member, which is connected to it, to engage with the second insertion segment, thereby locking the second insertion segment. Through the dual locking of the first and second insertion segments, even if the engagement between the first insertion segment and the first locking member is broken, the engagement between the second locking member and the second insertion segment still restricts the movement of the shackle relative to the lock body, thus maintaining the locked state of the NFC smart lock and improving the security of the NFC smart lock.

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0031] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0032] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0033] Currently, with the continuous development of locks, users' requirements for lock security are also gradually increasing. Traditional smart locks and mechanical locks usually adopt a one-way locking method, that is, existing locks include a lock body and a shackle. When one end of the shackle is inserted into the interior and the other end is inserted into the lock body, the locking element inside the lock body will lock that end. This locking method is relatively easy to open, resulting in low security. Consequently, traditional smart locks and mechanical locks are gradually becoming unable to meet users' requirements for lock security.

[0034] The inventors discovered that once the one-way locking mechanism of traditional smart locks and mechanical locks is broken, the shackle can move directly relative to the lock body to unlock it, resulting in low security. Furthermore, traditional mechanical locks rely on the key and lock cylinder to unlock, and with some experience, they can be easily unlocked using existing traditional mechanical unlocking tools, further contributing to their low security.

[0035] This invention proposes an NFC smart lock, aiming to solve the technical problem of how to improve the security of existing locks.

[0036] Please see Figure 1 , Figure 3 and Figure 6 In one embodiment of this utility model, the NFC smart lock 100 includes a lock body 1, a shackle 2, a locking mechanism 3, and a control module 4. The shackle 2 includes a first insertion section 21, a second insertion section 22, and a connecting section 23 connecting the first insertion section 21 and the second insertion section 22. The lock body 1 has a slot 11 and a slide groove 12. The second insertion section 22 slides with the wall of the slide groove 12. The second insertion section 22 includes a locked position and an unlocked position. The second insertion section 22 can reciprocate between the locked position and the unlocked position. When the second insertion section 22 is in the locked position, the first insertion section 21 is inserted into the slot 11. When the second insertion section 22 is in the unlocked position, the first insertion section 21 is disengaged from the slot 11. The locking mechanism 3 includes a first locking component 31 and a second locking component 32. The lock body 1 has a receiving cavity 15 inside that connects the slide groove 12 and the slot 11. The first locking component 31 and the second locking component 32 are located in the receiving cavity 15. The first locking component 31 includes a first driving member 311 and a first locking member 312 connected by transmission. The second locking component 32 includes a second driving member 321 and a second locking member 322 connected by transmission. When the second insertion segment 22 is in the locked position, the first driving member 311 can drive the first locking member 312 to engage with the first insertion segment 21, and the second driving member 321 can drive the second locking member 322 to engage with the second insertion segment 22, thereby restricting the second insertion segment 22 from leaving the locked position. The first driving member 311 and the second driving member 321 are both communicatively connected to the control module 4. The control module 4 can also communicate with the mobile terminal. The control module 4 is used to control the first driving member 311 to drive the first locking member 312 to move and to control the second driving member 321 to drive the second locking member 322 to move.

[0037] The technical solution of this utility model connects both the first driving member 311 and the second driving member 321 to the control module 4, enabling the control module 4 to control the first driving member 311 to engage or disengage the first locking member 312 with the first insertion section 21. The control module 4 can also control the second driving member 321 to engage or disengage the second locking member 322 with the second insertion section 22, thereby achieving double locking or unlocking of the shackle 2. Since this NFC smart lock 100 does not use the traditional lock cylinder and key unlocking method, traditional mechanical unlocking tools cannot unlock it using traditional unlocking methods, thus improving the security of the NFC smart lock 100. Furthermore, in this embodiment, in the second… When the insertion segment 22 is in the locked position, the first driving member 311 drives the first locking member 312, which is connected to it, to engage with the first insertion segment 21, thereby locking the first insertion segment 21. The second driving member 321 also drives the second locking member 322, which is connected to it, to engage with the second insertion segment 22, thereby locking the second insertion segment 22. This dual locking of the first and second insertion segments 21 prevents unauthorized unlocking of the NFC smart lock 100 in this embodiment from being performed using traditional unlocking techniques. Instead, it prevents the lock from being broken by forcibly unlocking the lock using the traditional one-way locking method. Even if the engagement between the first insertion segment 21 and the first locking member 312 is disrupted, or even if the first driving member 311 is also damaged... Even if the first locking member 322 is damaged, the second locking member 322 and the second insertion section 22 still engage to restrict the movement of the shackle 2 relative to the lock body 1, thereby maintaining the locked state of the NFC smart lock 100 and improving its security. Furthermore, damage to the first driving member 311 will not significantly affect the second driving member 321, allowing it to maintain the engagement between the second locking member 322 and the second insertion section 22. This avoids the situation where a single driving member driving two locking members would significantly reduce the difficulty of unlocking if that single member is damaged. Taking an electric push rod as an example, where the first driving member 311 and the second driving member 321 are electric push rods, existing electric push rods have self-locking capabilities. The function is such that even if the power is off, the extended section of the electric push rod will not retract. However, if the electric push rod is damaged, causing the internal self-locking structure to fail to function, the electric push rod will not be able to maintain the extended state, thus exiting the engagement state with the shackle 2. If only one drive is used to drive the two locking parts to lock the shackle 2, once the drive is damaged and the locking state of the shackle 2 cannot be maintained, the difficulty of unlocking will be greatly reduced. In this embodiment, since two independent drive parts, the first drive part 311 and the second drive part 321, are used, even if one drive part is damaged, the other drive part will still maintain the locking state of the shackle 2, effectively improving safety.Furthermore, since the NFC smart lock 100 of this embodiment features dual locking, it does not simply increase the number of locking elements locking the first insertion section 21. Instead, it uses the first locking member 312 and the second locking member 322 to lock the first insertion section 21 and the second insertion section 22 respectively. Even in the event of violent damage, such as forcefully pulling the shackle 2, the dual locking of the NFC smart lock 100 of this embodiment can effectively disperse the force, increasing the difficulty of unlocking and providing reliable protection for the user's property and personal safety.

[0038] It should be noted that the first driving component 311 and the second driving component 321 can be electric push rods, electric cylinders, or motors working in conjunction with gear and rack transmissions to move the first locking component 312 and the second locking component 322; the control module 4 can be implemented using existing control modules. The control module 4 can communicate with the mobile terminal using an existing Bluetooth transmission module. The user issues an unlocking command through the mobile terminal's APP (Application), and the mobile terminal transmits this unlocking command to the control module 4. After receiving the unlocking command, the control module 4 will... The first driving component 311 drives the first locking component 312 to separate from the first insertion section 21, and the second driving component 321 drives the second locking component 322 to separate from the second insertion section 22. When the control module 4 receives the locking command, the control module 4 controls the first driving component 311 to drive the first locking component 312 to engage with the first insertion section 21, thereby restricting the first insertion section 21 from moving upward relative to the lock body 1. The control module 4 also controls the second driving component 321 to drive the second locking component 322 to engage with the second insertion section 22, thereby restricting the second insertion section 22 from moving upward relative to the lock body 1, thus achieving double locking. Since this embodiment uses control module 4 to communicate with the mobile terminal (taking a mobile phone as an example), compared to unlocking with an electronic key, this embodiment undoubtedly has higher security by using control module 4 to communicate with the mobile terminal. This is because if an electronic key is obtained by someone else, they can directly perform the unlocking operation, while the mobile phone is different. Even if someone else obtains the mobile phone, they cannot access the mobile phone desktop through facial recognition or fingerprint recognition to open the APP and send the unlocking command. Therefore, using control module 4 to communicate with the mobile terminal is more secure.

[0039] It should also be noted that the first insertion segment 21 may have a slot for the first locking member 312 to extend into, thereby achieving a snap-fit ​​engagement with the first locking member 312. Alternatively, the first insertion segment 21 may have a hole for the first locking member 312 to pass through, thereby achieving a snap-fit ​​engagement with the first locking member 312. Similarly, the second insertion segment 22 may have a slot for the second locking member 322 to extend into, thereby achieving a snap-fit ​​engagement with the second locking member 322. Alternatively, the second insertion segment 22 may have a hole for the second locking member 322 to pass through, thereby achieving a snap-fit ​​engagement with the second locking member 322.

[0040] Please see Figures 2 to 4 In one embodiment, the first locking assembly 31 further includes a first guide member 313, which, along with the first driving member 311, is fixedly connected to the lock body 1. The first guide member 313 is slidably engaged with the first locking member 312. The second locking assembly 32 further includes a second guide member 323, which, along with the second driving member 321, is fixedly connected to the lock body 1. The second guide member 323 is slidably engaged with the second locking member 322. By setting the first guide member 313 to be slidably engaged with the first locking member 312, the movement of the first locking member 312 driven by the first driving member 311 is more stable. Similarly, by setting the second guide member 323 to be slidably engaged with the second locking member 322, the movement of the second locking member 322 driven by the second driving member 321 is more stable. It should be noted that the first guide member 313 may be provided with a groove 12, and the first locking member 312 may be provided with a slide rail that slides with the groove 12. Alternatively, the first guide member 313 may be provided with a slide rail, and the first locking member 312 may be provided with a groove 12 that slides with the slide rail. No specific restrictions are imposed here. Similarly, the second guide member 323 may be provided with a groove 12, and the second locking member 322 may be provided with a slide rail that slides with the groove 12. Alternatively, the second guide member 323 may be provided with a slide rail, and the second locking member 322 may be provided with a groove 12 that slides with the slide rail. No specific restrictions are imposed here either.

[0041] In one embodiment, the first guide member 313 is provided with a first sliding groove 12, and the first locking member 312 includes a first locking part 3121 and a first slider 3122 connected to each other. The first sliding groove 12 and the first slider 3122 are slidably engaged. The first locking part 3121 is convexly connected to the first driving member 311. The first driving member 311 is used to drive the first locking member 312 to engage or disengage from the first insertion section 21. The second guide member 323 is provided with a second sliding groove 12, and the second locking member 322 includes a second locking part 3221 and a second slider 3222 connected to each other. The second sliding groove 12 and the second slider 3222 are slidably engaged. The second locking part 3221 is convexly connected to the second driving member 321. The second driving member 321 is used to drive the second locking member 322 to engage or disengage from the second insertion section 22. By setting the first slider 3122 to slide in the first groove 12, the movement stability of the first locking part 3121 connected to the first slider 3122 is improved; similarly, by setting the second slider 3222 to slide in the second groove 12, the movement stability of the second locking part 3221 connected to the second slider 3222 is improved.

[0042] Please see Figure 2 and Figure 3 In one embodiment, the first insertion segment 21 has a first slot 211, and the first driving member 311 is used to drive the first locking member 312 to insert into or disengage from the first slot 211; the second insertion segment 22 has a second slot 221, and the second driving member 321 is used to drive the second locking member 322 to insert into or disengage from the second slot 221. When locking is required, the first driving member 311 drives the first locking part 3121 to extend into the first slot 211, and the second driving member 321 drives the second locking part 3221 to extend into the second slot 221, thereby achieving double locking. When unlocking is required, the first driving member 311 drives the first locking part 3121 to leave the first slot 211, and the second driving member 321 drives the second locking part 3221 to leave the second slot 221. It should be noted that both the first locking part 3121 and the second locking part 3221 extend and retract in opposite directions in the left and right directions. That is, when the first driving member 311 drives the first locking part 3121 to extend to the left, the second driving member 321 drives the second locking part 3221 to extend to the right, thereby achieving bidirectional locking and improving security. When the first driving member 311 drives the first locking part 3121 to retract to the right, the second driving member 321 drives the second locking part 3221 to retract to the left, thereby achieving bidirectional unlocking.

[0043] Please see Figure 2 and Figure 3In one embodiment, the slide groove 12 includes a through hole 121 and a mounting cavity 122 that are interconnected. The inner diameter of the mounting cavity 122 is larger than the inner diameter of the through hole 121. The second insertion segment 22 includes a body portion 222 and a limiting portion 223 that are interconnected. The end of the body portion 222 away from the limiting portion 223 is connected to the connecting segment 23. The limiting portion 223 is located inside the mounting cavity 122, and its outer diameter is larger than the inner diameter of the through hole 121. The limiting portion 223 slides in cooperation with the cavity wall of the mounting cavity 122, and the body portion 222 slides in cooperation with the hole wall of the through hole 121. By setting the limiting portion 223 to be located inside the mounting cavity 122, the body portion 222 is restricted from dislodging from the slide groove 12, thereby improving the reliability of the sliding cooperation between the second insertion segment 22 and the lock body 1. The outer wall of the body portion 222 slides in cooperation with the inner wall of the through hole 121, thereby improving the stability of the movement of the second insertion segment 22 relative to the through hole 121.

[0044] Please see Figure 2 and Figure 3 In one embodiment, the NFC smart lock 100 further includes an elastic element 5, which is located in the mounting cavity 122. One end of the elastic element 5 is connected to the limiting part 223, and the other end of the elastic element 5 is connected to the bottom wall of the mounting cavity 122. The elastic element 5 is used to drive the second insertion section 22 to move from the locking position to the unlocking position. During the locking process, the shackle 2 moves downward relative to the lock body 1, and the bottom of the second insertion section 22 compresses the elastic element 5. The shackle 2 continues to move downward against the elastic force of the elastic element 5 until the second insertion section 22 moves to the locked position. When the first driving member 311 drives the first locking part 3121 to extend to the left, the second driving member 321 drives the second locking part 3221 to extend to the right, thereby achieving bidirectional locking and restricting the shackle 2 from moving upward relative to the lock body 1 under the elastic force of the elastic element 5. During the unlocking process, when the first driving member 311 drives the first locking part 3121 to retract to the right, the second driving member 321 drives the second locking part 3221 to retract to the left, thereby achieving bidirectional unlocking. The elastic force of the elastic element 5 will drive the shackle 2 to move upward relative to the lock body 1, thereby moving the second insertion section 22 from the locked position to the unlocked position, eliminating the need for manual movement of the second insertion section 22 from the locked position to the unlocked position, and bringing a better user experience. It should be noted that the elastic element 5 can be a spring, or it can be rubber or other elastic elements 5, and no specific restrictions are made here.

[0045] Please see Figure 1 , Figure 4 and Figure 5In one embodiment, the control module 4 includes a control module 41 and an NFC (Near Field Communication) sensing module 42 connected in communication. The NFC sensing module 42 is disposed on the lock body 1. The first driving member 311 and the second driving member 321 are both connected in communication with the control module 4. The NFC sensing module 42 can also be connected in communication with a mobile terminal. The control module 4 is used to control the first driving member 311 to drive the first locking member 312 to move and to control the second driving member 321 to drive the second locking member 322 to move. By setting up an NFC sensing module 42, bidirectional interaction is achieved with the user's communication terminal. The user's communication terminal can be a mobile phone, tablet, or other mobile device; there are no restrictions here. Taking a mobile phone as an example, the user can issue unlocking or locking commands through an app installed on the phone. Taking the unlocking command as an example, the mobile terminal interacts with the NFC sensing module 42 through its own NFC module. After receiving the unlocking information, the NFC sensing module 42 transmits the information to the control module 41. When the control module 41 controls the first driving member 311 to drive the first locking part 3121 to retract to the right, the second driving member 321 drives the second locking part 3221 to retract to the left, thereby achieving bidirectional unlocking. It should be noted that the NFC sensing module 42 is an existing module, and the control module 41 is also an existing control module 41. It should also be noted that there are two control modules 41. The two control modules 41 are respectively connected to the first drive member 311 and the second drive member 321. That is, one control module 41 controls the first drive member 311 to drive the first locking part 3121 to extend or retract; the other control module 41 controls the second drive member 321 to drive the second locking part 3221 to extend or retract.

[0046] Please see Figure 5In one embodiment, the NFC smart lock 100 further includes a smart lock system 6. The smart lock system 6 includes a database module 61, a permission management module 62, and a lock information module 63, all interconnected. The lock information module 63 is also used for communication with a mobile terminal. Specifically, the lock information module 63 can transmit information such as the lock's status and operation records to the mobile terminal. The lock information module 63 can also receive user operation commands and configuration information from the mobile terminal, achieving efficient information interaction and improving ease of use. The permission management module 62, combined with the database module 61 and the lock information module 63, enables refined permission management. Personalized permissions can be flexibly set for different user roles, such as family members, temporary visitors, and property personnel. This precise permission management method ensures the security of the premises while improving management efficiency, meeting diverse needs in different scenarios. It should be noted that the database module 61, the permission management module 62, and the lock information module 63 can all be implemented using existing modules, and the communication connections between the modules and the mobile terminal can all be implemented using existing communication connection technologies.

[0047] Please see Figure 2 and Figure 3 In one embodiment, the NFC smart lock 100 further includes an electronic key 7 and a reader 8. A cavity 13 is provided inside the lock body 1 to accommodate the reader 8, and an insertion hole 14 for inserting the electronic key 7 is provided outside the lock body 1. The insertion hole 14 communicates with the cavity 13. The reader 8 is communicatively connected to the control module 4 and is used to detect whether the electronic key 7 is inserted into the insertion hole 14. By setting up the electronic key 7 and the reader 8, when the user is not carrying a mobile terminal, the user can insert the electronic key 7 into the insertion hole 14. After the reader 8 recognizes that the electronic key 7 is inserted into the insertion hole 14, the reader 8 sends the information about the electronic key 7 being inserted into the insertion hole 14 to the control module 41. When the control module 41 controls the first driving member 311 to drive the first locking part 3121 to retract to the right, the second driving member 321 drives the second locking part 3221 to retract to the left, thereby achieving bidirectional unlocking without the aid of a mobile terminal.

[0048] According to one embodiment of the present invention, the NFC smart lock 100 further includes a dustproof plate 20 and a torsion spring (not shown in the figure). The dustproof plate 20 is rotatably mounted on the lock body 1 so that the dustproof plate 20 can block or expose the insertion hole 14. The torsion spring is disposed on the lock body 1 and is used to drive the dustproof plate 20 to block the insertion hole 14, preventing external dust from entering the insertion hole 14, and providing a guarantee for the reader 8 to accurately identify the electronic key 7 located in the insertion hole 14.

[0049] Please see Figure 2 and Figure 3 In one embodiment, the NFC smart lock 100 further includes an elastic anti-collision block 9, which is sleeved around the periphery of the connecting section 23. The elastic anti-collision block 9 provides cushioning for the up-and-down movement of the shackle 2, reducing wear caused by collisions between the shackle 2 and other components. It should be noted that the elastic anti-collision block can be a rubber anti-collision block or a polyurethane anti-collision block.

[0050] Please see Figure 2 and Figure 3 In one embodiment, the NFC smart lock 100 further includes a guide 10, which has a guide hole 101. The guide 10 is connected to the lock body 1, and the guide hole 101 is oriented towards and communicates with the slot 11. The diameter of the guide hole 101 gradually widens along the extension direction of the slot 11 in a direction away from the slot 11. By providing the guide 10 and the guide hole on the guide 10, the first insertion segment 21 can be more accurately inserted into the slot 11, improving the convenience of locking.
