Description

Technical Field

[0001] This utility model relates to the field of lock technology, and more specifically, to a smart lock cylinder security lock. Background Technology

[0002] Currently, lock cylinders are mainly divided into two categories: mechanical lock cylinders and electronic lock cylinders. Mechanical lock cylinders have a simple structure and low cost, but their security is relatively low, making them easy to pick using technical means, thus limiting their ability to achieve intelligent and refined management. Secondly, mechanical lock cylinders are more difficult to manufacture, have complex assembly processes, and fewer locking points. Electronic lock cylinders offer higher security and convenience, and can be unlocked through various methods such as fingerprint recognition, password input, and card swiping. However, electronic lock cylinders rely on a power source, requiring regular battery replacements or an uninterrupted external power supply, which may not be sufficient in harsh environments. Furthermore, electronic lock cylinders have a higher unit cost, require initial wiring for installation, and necessitate regular specialized maintenance.

[0003] Secondly, traditional security locks often rely on the user's active operation to lock. If the user forgets to turn the bolt or press the lock button after taking out the electronic key, the lock will not lock, resulting in the user forgetting to lock it. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an intelligent lock cylinder security lock to solve the problem that existing locks are prone to being left unlocked during use.

[0005] The technical solution of this utility model is as follows: A smart lock cylinder security lock, comprising:

[0006] The mounting bracket has a first mounting hole that extends through both the front and rear ends of the mounting bracket.

[0007] A lock cylinder assembly, wherein the lock cylinder assembly is installed in the first mounting hole;

[0008] The lock cylinder assembly includes a lock body, which contains a drive assembly, a stop member, and a rotation positioning assembly. The drive assembly drives the stop member to rotate. The rotation positioning assembly includes a magnetic element and a sensing unit. The sensing unit is disposed on the lock body, and the magnetic element is embedded in the stop member. When the stop member rotates to the stop position, the magnetic element is positioned above the sensing unit, and the sensing unit sends a locking signal.

[0009] Furthermore, the mounting bracket includes a main body and a mating part fixedly connected to the main body. The mating part includes an annular bottom wall, an annular side wall, and an annular flange formed by the upper part of the annular side wall extending radially inward along the annular side wall. The annular flange, the annular bottom wall, and the annular side wall define a limiting space for mating with an electronic key. The annular flange is provided with at least one first notch, which is used to mate with a locking protrusion on the electronic key. When the electronic key is rotated to a predetermined position, the first notch aligns with the locking protrusion on the electronic key, so that the electronic key can be pulled out.

[0010] Furthermore, the lock body is provided with an elastic limiting component, the inner wall of the mounting bracket is provided with an arc-shaped groove that cooperates with the elastic limiting component, the stop member is provided with a plurality of spaced protrusions, and a receiving position is formed between two adjacent protrusions. The elastic limiting component can move radially along the lock body to switch between a locked position and a released position. When the elastic limiting component is in the locked position, one end of the elastic limiting component is embedded in the arc-shaped groove, and the other end of the elastic limiting component corresponds to the protrusion. When the elastic limiting component is in the released position, one end of the elastic limiting component disengages from the arc-shaped groove, and the other end of the elastic limiting component is embedded in the receiving position.

[0011] Furthermore, the drive assembly includes a drive motor and a control circuit board. The drive motor and the control circuit board are connected, and the drive motor is connected to the stop member. The drive motor can drive the stop member to rotate so that the stop member can switch between a stop position and a release position. When the stop member is in the stop position, the protrusion abuts against one end of the elastic limiting component so that the other end of the elastic limiting component is embedded in the arc-shaped groove. When the stop member is in the release position, the protrusion and the elastic limiting component are offset from each other, and the elastic limiting component can move radially inward along the lock body so that the elastic limiting component disengages from the arc-shaped groove.

[0012] Furthermore, the lock cylinder assembly also includes a lock cover, and a second mounting hole is provided at one end of the lock body. At least a portion of the lock cover is installed in the second mounting hole. A plurality of conductive posts are embedded on the lock cover, and the plurality of conductive posts are in contact with a plurality of conductive contacts on the control circuit board.

[0013] Furthermore, the lock body is provided with a stepped hole arranged radially along the lock body, and the elastic limiting component passes through the stepped hole.

[0014] Furthermore, the elastic limiting component includes a push rod and a spring sleeved on the push rod. The push rod includes a first rod body and a second rod body, and an annular platform is formed between the first rod body and the second rod body. One end of the spring abuts against the annular platform, and the other end of the spring abuts against the inner wall of the stepped hole.

[0015] Furthermore, it also includes a latch, which is fixedly mounted on the lock body by fasteners. When the elastic limiting component is in the released position, the lock body can rotate relative to the mounting bracket so that the latch moves to the unlock position.

[0016] Furthermore, the lock body includes a first lock body and a second lock body. The second lock body is embedded in the end of the first lock body away from the lock cover. The end of the first lock body away from the second lock body is provided with a groove formed by the inward indentation of the outer wall of the first lock body. The groove is used to cooperate with an electronic key. The outer wall of the first lock body is provided with a plurality of annular grooves. A sealing ring is embedded in the plurality of annular grooves. The sealing ring is used to seal the gap between the first lock body and the mounting bracket.

[0017] Furthermore, the sensing unit is a Hall sensor.

[0018] According to the above-described solution, the beneficial effects of this utility model are as follows: This utility model provides an intelligent lock cylinder safety lock, including a mounting bracket and a lock cylinder assembly. The mounting bracket has a first mounting hole penetrating both ends of the mounting bracket. The lock cylinder assembly is installed in the first mounting hole. The lock cylinder assembly includes a lock body, which contains a drive assembly, a stop member, and a rotation positioning assembly. The drive assembly drives the stop member to rotate. The rotation positioning assembly includes a magnetic element and a sensing unit. The sensing unit is located on the lock body, and the magnetic element is embedded in the stop member. When the stop member rotates to the stop position, the magnetic element is positioned above the sensing unit, and the sensing unit emits a locking signal. The electronic key receives this locking signal and displays that the safety lock is locked through the electronic key's display screen. This allows staff to quickly know that the locking action has been completed through the display screen, thus avoiding the phenomenon of accidentally missing the lock. Attached Figure Description

[0029] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this utility model by way of example, but should not be used to limit the scope of this utility model, that is, this utility model is not limited to the described embodiments.

[0030] To better understand this utility model, the following description, in conjunction with the accompanying drawings and embodiments, will further illustrate the present utility model:

[0031] See Figures 1-3 As shown in the figure, an intelligent lock cylinder security lock provided by this utility model embodiment includes a mounting bracket 1 and a lock cylinder assembly 2. The lock cylinder assembly 2 is installed in the mounting bracket 1. The outer wall of the mounting bracket 1 is provided with an external thread. A nut 4 is sleeved on the mounting bracket 1, and the internal thread of the nut 4 is engaged with the external thread of the mounting bracket 1. In this embodiment, the mounting bracket 1 is installed on an external device, wherein the external device includes, but is not limited to, a cash box, an ATM machine, a VTM machine, a ring main unit, a distribution cabinet, a switching station, a switch station, a junction box, a capacitor compensation integrated distribution box, a terminal box, a metering box, and a multi-user meter box.

[0032] It is worth mentioning that the smart lock cylinder security lock provided in this embodiment does not require an external power source or a built-in battery. The smart lock cylinder security lock adopts a closed technology, with the electronic key 5 providing power and identification information. Users can achieve comprehensive management of the lock through the electronic key 5 and the smart lock control management software. The electronic key 5 provides power and identification information, while the smart lock control management software sets unlocking permissions and uploads unlocking records. The smart lock control management system realizes the functions of permission setting, door lock status viewing, unlocking record storage and retrieval, and lock information management.

[0033] The smart lock cylinder security lock provided in this embodiment of the utility model primarily relies on the contact power supply and identity verification between the electronic key 5 and the smart lock cylinder security lock. Specifically, when the electronic key 5 is inserted into the smart lock cylinder security lock, the electronic key 5 provides power to the smart lock cylinder security lock through reverse power supply and performs dynamic key verification. Once verification is successful, the lock can be unlocked. In addition, in some embodiments, the electronic key 5 also supports remote authorization via wireless technologies such as Bluetooth and NFC.

[0034] See Figures 2-3 As shown, the mounting bracket 1 has a first mounting hole 1a extending through both ends of the mounting bracket 1, and the lock cylinder assembly 2 is installed in the first mounting hole 1a. When the electronic key 5 is inserted into the smart lock cylinder security lock and dynamic key verification is performed, after successful verification, turning the electronic key 5 will cause the lock cylinder assembly 2 to rotate relative to the mounting bracket 1 within the first mounting hole 1a, thereby unlocking the lock. It should be noted that this embodiment does not involve improvements to the data interaction process between the electronic key 5 and the remote terminal, or between the electronic key 5 and the smart lock cylinder security lock; therefore, this embodiment will not elaborate on this part.

[0035] See Figure 3As shown, the mounting bracket 1 includes a main body 11 and a mating part 12 fixedly connected to the main body 11. In this embodiment, the main body 11 and the mating part 12 are an integral structure. The mating part 12 is disposed on one end of the main body 11 for engaging with the electronic key 5.

[0036] Specifically, the mating part 12 includes an annular bottom wall 121, an annular side wall 122, and an annular flange 123 formed by the upper part of the annular side wall 122 extending radially inward along the annular side wall 122. The annular flange 123, the annular bottom wall 121, and the annular side wall 122 define a limiting space 124 for mating with the electronic key 5. The annular flange 123 is provided with at least one first notch 1231, which is used to mate with the locking protrusion 51 on the electronic key 5. When the electronic key 5 is rotated to a predetermined position, the first notch 1231 aligns with the locking protrusion 51 on the electronic key 5 so that the electronic key 5 can be pulled out. In this embodiment, the annular flange 123, the annular bottom wall 121, and the annular side wall 122 together define a limiting space 124 for matching the electronic key 5. When the electronic key 5 is inserted, it is necessary to ensure that the locking protrusion 51 on the electronic key 5 is aligned with the first notch 1231 on the annular flange 123. Then, a portion of the electronic key 5 is inserted into the limiting space 124 so that the electronic key 5 can engage with the lock cylinder assembly 2. When the electronic key 5 is rotated to unlock, the locking protrusion 51 and the first notch 1231 on the electronic key 5 are misaligned, so that the electronic key 5 cannot be pulled out from the mating part 12. When the electronic key 5 is rotated to the predetermined position to lock, the first notch 1231 is aligned with the locking protrusion 51 on the electronic key 5 so that the electronic key 5 can be pulled out, thereby effectively preventing the lock from being left unlocked due to accidental removal of the electronic key 5 after unlocking.

[0037] See Figures 4-5 As shown, the lock cylinder assembly 2 includes a lock body 21, and a drive assembly 22, a stop member 23 and an elastic limiting assembly 24 are provided inside the lock body 21. The stop member 23 and the drive assembly 22 are fixedly connected. The drive assembly 22 drives the stop member 23 to rotate so that the elastic limiting assembly 24 can switch between the locked position and the released position.

[0038] Specifically, the inner wall of the mounting bracket 1 is provided with an arc-shaped groove 13 that cooperates with the elastic limiting component 24. The design of the arc-shaped groove 13 allows the end of the elastic limiting component 24 that contacts the arc-shaped groove 13 to move along the arc-shaped inner wall of the arc-shaped groove 13 under the action of external force. The elastic limiting component 24 can exit from or be inserted into the arc-shaped groove 13.

[0039] In this embodiment, the stop member 23 is provided with a plurality of spaced protrusions 231, and a receiving position is formed between two adjacent protrusions 231. The receiving position is used for one end of the elastic limiting component 24 to pass through it. When the stop member 23 is rotated to the first position, the protrusions 231 abut against one end of the elastic limiting component 24, thereby causing the other end of the elastic limiting component 24 to be embedded in the arc-shaped groove 13. When the stop member 23 is rotated to the second position, the protrusions 231 and the elastic limiting component 24 are misaligned, thereby causing one end of the elastic limiting component 24 to be embedded in the receiving position. Under the action of external force (turning the electronic key 5), the elastic limiting component 24 can move outward along the arc-shaped inner wall of the arc-shaped groove 13, thereby disengaging from the arc-shaped groove 13 and completing the unlocking action.

[0040] Specifically, the elastic limiting component 24 can move radially along the lock body 21 to switch between a locked position and a released position. When the elastic limiting component 24 is in the locked position, one end of the elastic limiting component 24 is embedded in the arc-shaped groove 13, and the other end of the elastic limiting component 24 corresponds to the protrusion 231. When the elastic limiting component 24 is in the released position, one end of the elastic limiting component 24 is disengaged from the arc-shaped groove 13, and the other end of the elastic limiting component 24 is embedded in the receiving position.

[0041] See Figures 4-5 As shown, the drive assembly 22 includes a drive motor 221 and a control circuit board 222. The drive motor 221 and the control circuit board 222 are connected, and the output end of the drive motor 221 is connected to the stop member 23.

[0042] When the electronic key 5 is inserted into the smart lock cylinder security lock, the electronic key 5 provides power to the smart lock cylinder security lock through reverse power supply and performs dynamic key verification. After successful verification, the drive motor 221 rotates to drive the stop 23 to rotate, thereby causing the stop 23 to switch from the stop position to the release position. When the stop 23 is in the release position, the protrusion 231 and the elastic limiting component 24 are offset from each other, and the receiving position and the elastic limiting component 24 are aligned. At this time, when the electronic key 5 is turned, the elastic limiting component 24 can move outward along the arc-shaped inner wall of the arc-shaped groove 13, thereby exiting from the arc-shaped groove 13 and completing the unlocking action.

[0043] It should be noted that the stop member 23 in this embodiment can switch between a stop position and a release position under the drive of the drive motor 221. When the stop member 23 is in the stop position, the protrusion 231 abuts against one end of the elastic limiting component 24, so that the other end of the elastic limiting component 24 is embedded in the arc groove 13. When the stop member 23 is in the release position, the protrusion 231 and the elastic limiting component 24 are offset from each other, and the elastic limiting component 24 can move inward along the radial direction of the lock body 21 so that the elastic limiting component 24 disengages from the arc groove 13.

[0044] See Figure 4 As shown, the lock cylinder assembly 2 also includes a lock cover 25. A second mounting hole 213 is provided at one end of the lock body 21. At least a portion of the lock cover 25 is installed within the second mounting hole 213. Multiple conductive posts 26 are embedded in the lock cover 25, and these conductive posts 26 contact multiple conductive contacts on the control circuit board 222. With this design, when the electronic key 5 is inserted into the security lock equipped with this smart lock cylinder, the multiple conductive pins 52 on the electronic key 5 correspond one-to-one with and contact the multiple conductive posts 26, thereby providing power to the security lock through reverse power supply.

[0045] See Figure 4 , Figure 6 and Figure 7 As shown, the lock body 21 is provided with a stepped hole 214 arranged radially along the lock body 21, and the elastic limiting component 24 passes through the stepped hole 214.

[0046] Specifically, the elastic limiting component 24 includes a push rod 241 and a spring 242 sleeved on the push rod 241. The push rod 241 includes a first rod body 2411 and a second rod body 2412, with an annular platform formed between the first rod body 2411 and the second rod body 2412. One end of the spring 242 abuts against the annular platform, and the other end of the spring 242 abuts against the inner wall of the stepped hole 214. This design allows the spring 242 to return to its original position. When the lock cylinder assembly 2 rotates to the locked position, i.e., when the push rod 241 is aligned with the arc-shaped groove 13 located on the inner wall of the mounting bracket 1, the spring 242 drives the push rod 241 to engage in the arc-shaped groove 13, thereby completing the locking action.

[0047] See Figures 4-5 As shown, the intelligent lock cylinder security lock provided by this utility model also includes a bolt 27. The bolt 27 is fixedly installed on the lock body 21 by fasteners 28. When the elastic limiting component 24 is in the released position, the lock body 21 can rotate relative to the mounting support 1 so that the bolt 27 moves to the unlocking position.

[0048] In this embodiment, a rotation positioning component 29 is provided inside the lock body 21. The rotation positioning component 29 includes a magnetic component 291 and a sensing unit 292. The sensing unit 292 is connected to the control circuit board 222. The magnetic component 291 is embedded in the stop component 23. When the stop component 23 rotates to the stop position, the magnetic component 291 is located above the sensing unit 292. The sensing unit 292 sends a locking signal. The electronic key 5 receives the locking signal and displays it on the display screen, so that the staff can quickly know that the locking action has been completed through the display screen, further preventing the phenomenon of missing the lock.

[0049] Specifically, the sensing unit 292 in this embodiment is a Hall sensor.

[0050] See Figure 5 As shown, the lock body 21 includes a first lock body 211 and a second lock body 212. The second lock body 212 is embedded on the end of the first lock body 211 away from the lock cover 25. The end of the first lock body 211 away from the second lock body 212 is provided with a groove 2111 formed by the inward indentation of the outer wall of the first lock body 211. The groove 2111 is used to cooperate with the electronic key 5.

[0051] To prevent moisture from the outside air from entering the smart lock cylinder security lock, in this embodiment, the outer wall of the first lock body 211 is provided with a plurality of annular grooves 2112, and a sealing ring 3 is embedded in the plurality of annular grooves 2112. The sealing ring 3 is used to seal the gap between the first lock body 211 and the mounting bracket 1.

[0052] More specifically, there is a gap between the inner wall of the lock cover 25 and the second mounting hole 213, which is filled with sealant.

[0053] To further illustrate this point, this embodiment also provides the unlocking process of the aforementioned smart lock cylinder security lock, as follows:

[0054] Step 1: Insert the electronic key 5 into the safety lock with the key facing it. Align the protrusion 51 on the electronic key 5 with the first notch 1231 on the annular flange 123 and insert it so that the end of the electronic key 5 with the protrusion 51 is embedded in the limiting space 124. At this time, the multiple conductive pins 52 on the electronic key 5 correspond one-to-one with the multiple conductive posts 26 and are in contact with each other. The electronic key 5 provides power to the safety lock by reverse power supply.

[0055] Step 2: The security lock and electronic key 5 perform dynamic key verification through data interaction. After successful verification, the drive motor 221 rotates, causing the stop 23 to rotate, so that the stop 23 switches from the stop position to the release position. At this time, the protrusion 231 of the stop 23 and the elastic limiting component 24 are misaligned, and the receiving position of the stop 23 and the elastic limiting component 24 are aligned.

[0056] Step 3: Turn the electronic key 5 to cause the lock cylinder assembly 2 to rotate, thereby causing the push rod 241 to exit from the arc groove 13. At the same time, the bolt 27 also rotates to the unlock position, thus completing the unlocking action. At this time, the locking protrusion 51 on the electronic key 5 is misaligned with the first notch 1231, and the electronic key 5 cannot be pulled out.

[0057] Step 4: Turn the electronic key 5 again, causing the lock cylinder assembly 2 to rotate accordingly. When the push rod 241 aligns with the arc-shaped groove 13, driven by the spring 242, the push rod 241 is inserted into the arc-shaped groove 13. At the same time, not only does the bolt 27 move to the locked position, but the magnetic component 291 is also positioned above the sensing unit 292. The sensing unit 292 sends a locking signal, which the electronic key 5 receives. At this time, the latch 51 on the electronic key 5 aligns with the first notch 1231, and the electronic key 5 can be pulled out.

[0058] Step 5: Drive motor 221 rotates, causing stop 23 to rotate, so that stop 23 switches from the release position to the stop position. At this time, the protrusion 231 of stop 23 and elastic limiting component 24 are aligned and in contact, and the receiving position of stop 23 and elastic limiting component 24 are misaligned, thereby completing the locking action.
