Description

Technical Field

[0001] This utility model relates to the field of lock cylinder technology, specifically a lock cylinder structure with a door closure detection function. Background Technology

[0002] The lock cylinder is one of the most important parts of a lock. It refers to the rotating component inside the lock, typically containing a keyhole and a series of pins or tumblers. When the correct key is inserted into the lock cylinder and turned, it actuates the mechanism inside the lock body, thereby opening or closing the lock. Lock cylinder designs vary widely to suit different security needs and usage scenarios.

[0003] In existing technologies, after successful verification of the lock cylinder and key, the lock cylinder allows its internal shaft to rotate, thereby moving the locking mechanism inside the lock body to open and close the lock. However, the security and practicality of unlocking by relying solely on the mechanical linkage between the lock cylinder and key in existing technologies are insufficient. Furthermore, users often assume the lock is locked when closing the door, which can easily lead to forgetting to close it. In addition, existing lock cylinders do not have a lock cylinder structure that can detect whether the door has been forgotten to be closed, which may result in the loss of valuables after the user leaves. To improve the security of the lock cylinder, we propose a lock cylinder structure with a door-forgot detection feature. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lock cylinder structure with a door-closed-in-place detection feature. If the locking rod is not inserted, the lock cylinder cannot rotate, and the electronic key cannot be removed, thus reminding the user to lock the door properly. To remove the electronic key, the user must insert the locking rod into the lock block. After insertion, a first Hall sensor detects the position of the second magnet, and a second Hall sensor detects the position of the lock block. Only then can the lock cylinder rotate, allowing the user to remove the electronic key. This achieves door-closed-in-place detection, preventing the door from being left closed and solving the problems mentioned earlier.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lock cylinder structure with a door closure detection feature, comprising a lock housing, a insert rod, a lock block, and a key rod.

[0008] Preferably, the key-holding assembly includes a fixing block, which is fixedly connected to the top side of the rotating cylinder two. The top of the rotating cylinder two has an insertion hole, and the bottom end of the key bar is inserted into the insertion hole.

An annular slot and a straight groove are formed on the outer surface of the key bar. The fixing rod one is slidably connected to the annular slot, and the fixing rod two is slidably connected to the straight groove. Two sets of sensing rod one are provided on the top of the circuit board. The top ends of the two sets of sensing rod one penetrate the bottom side of the insertion hole and extend into the interior of the insertion hole. Two sets of sensing rod two are fixedly connected to the bottom end of the key bar, and the sensing rod one abuts against the sensing rod two.

[0009] Preferably, the door leakage detection component includes a first Hall sensor and a second Hall sensor. The first Hall sensor is disposed at the bottom of the circuit board, and the second Hall sensor is disposed at the bottom rear side of the lock housing.

[0014] Preferably, the outer surface of the front end of the insertion rod is also provided with an arc-shaped groove.

[0015] This invention provides a lock cylinder structure with a door-closing detection feature. Compared with existing technologies, it has the following advantages:

[0016] 1. This lock cylinder structure with door closure detection has a drive motor fixedly installed on the left side inside the lock housing. The drive motor drives a rotating block to rotate. The lock cylinder assembly is installed on the rotating cylinder. When the key bar is inserted into the mortise, the sensing rod 1 and sensing rod 2 on the top of the circuit board form a passage, causing the drive motor 2 to rotate the limiting block, thereby releasing the limiting block from the stop block, allowing the rotating cylinder 3 to rotate on the rotating cylinder 1. When the movable rod on the placement slot aligns with the slot 2 and slot 1, the movable rod sinks into slot 2, allowing the rotating cylinder 1 to rotate. When the groove 3 on the outer surface of the rotating cylinder 1 abuts against the ball, the mortise bar can be pulled out to unlock. The combination of mechanical and electronic unlocking improves the security of the lock cylinder. Furthermore, the groove 2 on the outer surface of the rotating block allows the drive motor 1 to rotate the rotating block with an electronic key, causing the groove 2 to abut against the ball, or the mortise bar to be pulled out to unlock, thus realizing two unlocking methods and improving practicality.

[0017] 2. This lock cylinder structure with a door-closing detection feature also includes a door-closing detection component installed inside the lock housing. Through the cooperation of a second Hall sensor and a first magnet, it detects whether the spool has been inserted into the lock block. During the opening process, the lock first senses the lock cylinder rotating to open, and then senses the spool being pulled out of the lock block, thus completing the opening detection process. During the closing process, the lock first senses the spool being inserted into the lock block, and then the lock cylinder rotates back to its original position and is pulled out, thus completing the closing detection process. If the second Hall sensor and the first magnet do not detect the door being closed after closing, a door-closing failure is detected, and the user is alerted, thus strengthening on-site security control.

[0018] 3. The lock cylinder structure with door closure detection has a key retention assembly installed between the key bar and the lock cylinder. When the key bar is inserted, both fixing rod one and fixing rod two slide on the straight groove until fixing rod one slides into the annular slot. When the key bar is turned to unlock, fixing rod one is stuck in the annular slot. If the key bar is not turned back to its original position, it cannot be pulled out of the mortise. A top groove is provided on the outer surface of the rear end of the mortise. A spring is provided on the bottom right side of the lock body. A top block is fixedly connected to the top of the spring. The top side of the top block abuts against the inner surface of the top groove. When the lock cylinder is unlocked and the mortise is pulled out, the mortise is fixed by the top block and the top groove. If the mortise is not inserted back to its original position, the abutment of the mortise causes the ball to be stuck in the groove three opened on the outer surface of the rotating cylinder one, so that the lock cylinder cannot rotate, realizing the forced locking and closing function, avoiding the management failure problem caused by non-locking.

Detailed Implementation

[0034] 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 protection scope of the present utility model.

[0035] Please see Figure 1-14This utility model provides a technical solution: a lock cylinder structure with a door closure detection function, including a lock housing 1, a rod 4, a lock block 6, and a key bar 38. A key hole 3 is provided through the top left side of the lock housing 1, and the key bar 38 is inserted into the key hole 3. The rod 4 is movably inserted through the right side of the lock housing 1. The lock block 6 is located at the bottom right side of the lock housing 1, and the rear end of the rod 4 is inserted into the lock block 6. The interior of the lock housing 1 is provided with a ball bearing channel 9 and a rotating cylinder groove 33. A rotating cylinder 14 is rotatably connected to the rotating cylinder groove 33. A ball bearing groove 24 is provided through the rotating cylinder 14, and a groove 23 is provided on the outer surface of the rotating cylinder 14. Several balls 10 are provided on both the channel 9 and the ball groove 24. A groove 8 is provided on the outer surface of the insertion rod 4. The ball 10 located on the far right inside the ball channel 9 abuts against the groove 8. A drive motor 11 is fixedly installed on the left side inside the lock housing 1. A rotating block 12 is fixedly inserted into the output shaft end of the drive motor 11. The ball 10 located on the left side inside the ball groove 24 abuts against the rotating block 12. A groove 13 is provided on the outer surface of the rotating block 12. A lock cylinder assembly is installed on the rotating cylinder 14. A key retention assembly is installed between the key rod 38 and the lock cylinder assembly. A door closure detection assembly is also installed inside the lock housing 1.

[0036] The device, authorized by an electronic key, drives the drive motor 11 to rotate the rotating block 12, causing the groove 13 on the outer surface of the rotating block 12 to engage with the ball bearings 10. As the balls 10 roll within the ball bearing channel 9 and the ball bearing groove 24, the engagement between the balls 10 and the groove 8 on the outer surface of the insertion rod 4 is released. At this point, the insertion rod 4 can be pulled to disengage from the lock block 6 and unlock. A lock cylinder assembly is installed on the rotating cylinder 14 to enable unlocking via the lock cylinder. A key retention assembly enables forced locking and closing functions, avoiding management failures caused by incomplete locking. A door closure detection assembly detects any missed door closures and alerts the user, strengthening on-site security control.

[0037] The lock cylinder assembly includes a second rotating cylinder 17 and a third rotating cylinder 20. The second rotating cylinder 17 is snapped onto the top of the third rotating cylinder 20. A sliding groove 27 is provided at the bottom of the third rotating cylinder 20. A fixing plate 21 is fixedly connected to the top side of the first rotating cylinder 14. The fixing plate 21 is slidably connected to the sliding groove 27. A placement groove 26 is provided on the fixing plate 21. A movable rod 25 is placed on the placement groove 26. A second locking groove 35 is provided on the outer surface of the bottom of the third rotating cylinder 20. A first locking groove 34 is provided on the inner wall of the rotating cylinder groove 33. A locking mechanism is installed inside the third rotating cylinder 20.

[0038] The locking mechanism includes a circuit board 18, which is located inside the rotating drum 20. A drive motor 29 is mounted on the circuit board 18. A mounting groove 28 is provided at the bottom of the rotating drum 20. A limit block 30 is provided on the mounting groove 28. The limit block 30 is fixedly sleeved on the output shaft end of the drive motor 29. A stop block 31 is fixedly connected to the inner wall of the rotating drum 14. One end of the limit block 30 abuts against the stop block 31.

[0039] The key-holding assembly includes a fixing block 36, which is fixedly connected to the top side of the rotating cylinder 17. The top of the rotating cylinder 17 has an insertion hole 15, and the bottom end of the key rod 38 is inserted into the insertion hole 15. The fixing block 36 is fixedly connected to a fixing rod 16 and a fixing rod 37 on the side near the insertion hole 15. The outer surface of the key rod 38 has an annular slot 39 and a straight groove 40. The fixing rod 16 is slidably connected to the annular slot 39, and the fixing rod 37 is slidably connected to the straight groove 40. The top of the circuit board 18 is provided with two sets of sensor rods 19. The top ends of the two sets of sensor rods 19 penetrate the bottom side of the insertion hole 15 and extend into the interior of the insertion hole 15. The bottom end of the key rod 38 is fixedly connected to two sets of sensor rods 41, and the sensor rods 19 and 41 abut against each other.

[0040] The key bar 38 is inserted into the socket 15 through the lock hole 3. Both the first fixing rod 16 and the second fixing rod 37 slide on the straight groove 40 until the first fixing rod 16 slides into the annular slot 39. This creates a pathway between the second sensing rod 41 of the key bar 38 and the first sensing rod 19 located at the top of the circuit board 18. This causes the second drive motor 29 to rotate the limiting block 30, releasing the fixation of the stop block 31. This allows the first rotating drum 14 and the third rotating drum 20 to rotate relative to each other. At this time, the key, through the fixation of the first fixing rod 16, rotates the second rotating drum 17, which in turn rotates the third rotating drum 20. When the bottom outer surface of the third rotating drum 20 is opened... The inner wall of the slot 35 and the rotating cylinder groove 33 has a slot 34. When the movable rod 25 is aligned with the slot 35, the movable rod 25 is inserted into the slot 35 and disengaged from the slot 34, allowing the rotating cylinder 14 to rotate on the rotating cylinder groove 33. The groove 23 on the outer surface of the rotating cylinder 14 is engaged with the ball 10, allowing the groove 8 on the insert rod 4 to disengage from the ball 10, thus completing the key rod 38 to turn and unlock. At this time, the insert rod 4 is pulled out from the lock block 6 to complete the door opening, and the fixing rod 16 is locked in the annular slot 39. If the key rod 38 is not rotated back to its original position, it cannot be pulled out from the insertion hole 15.

[0041] The door leakage detection component includes a first Hall sensor 42 and a second Hall sensor 44. The first Hall sensor 42 is located at the bottom of the circuit board 18, and the second Hall sensor 44 is located at the bottom rear side of the lock housing 1. A second magnet block 45 is located inside the rotating cylinder 14, and a first magnet block 43 is located on the left side of the lock block 6.

[0042] During the rotation of the lock cylinder, the changes in the sensing signals of the first Hall sensor 42 at the bottom of the circuit board 18 and the second magnet 45 inside the rotating cylinder 14 detect whether the lock cylinder is rotating. During the insertion and removal of the locking block 6 by the insertion rod 4, the changes in the sensing signals of the second Hall sensor 44 on the rear bottom of the lock housing 1 and the first magnet 43 on the left side of the locking block 6 detect whether the insertion rod 4 is inserted into the locking block 6. During the opening process, the lock first senses the signal from the first Hall sensor 42 through the rotation of the lock cylinder, and then senses the signal from the second Hall sensor 45 when the insertion rod 4 removes the locking block 6. The signal from the two Hall sensors 44 is used to detect the opening process. During the closing process, the lock first senses the signal from the second Hall sensor 44 by pulling out the lock block 6 through the insertion rod 4, then senses the signal from the first Hall sensor 42 by rotating the lock cylinder, and finally pulls out the lock cylinder, thus completing the detection of the closing process. If only the signal from the first Hall sensor 42 when the lock cylinder rotates is sensed after the door is closed, and the signal from the second Hall sensor 44 when the insertion rod 4 pulls out the lock block 6 is not sensed, it can detect that the user has forgotten to close the door and remind the user to close the door again, thus strengthening on-site security control.

[0043] A mounting base plate 5 is fixedly installed on the bottom side of the lock housing 1. The bottom side of the rotating cylinder 14 is rotatably connected to the mounting base plate 5. A limit rod 22 is fixedly connected to the top of the mounting base plate 5. A limit groove 32 is opened at the bottom of the rotating cylinder 14. The limit rod 22 is slidably connected to the limit groove 32. The rotation angle of the rotating cylinder 14 is limited by the cooperation between the limit rod 22 and the limit groove 32.

[0044] The outer surface of the rear end of the insertion rod 4 is provided with a top groove 48. A spring 46 is provided at the bottom right side of the lock housing 1. A top block 47 is fixedly connected to the top of the spring 46. The top side of the top block 47 abuts against the inner surface of the top groove 48. If the insertion rod 4 is not inserted back into its original position, the abutment of the insertion rod 4 will cause the ball 10 to be stuck in the groove 23 on the outer surface of the rotating cylinder 14, making the lock cylinder unable to rotate.

[0045] The bottom of the lock housing 1 has several bolt mounting holes 7 to facilitate the installation of the lock housing 1.

[0046] A lock hole cover 2 is hinged to the left side of the lock housing 1 to prevent dust from entering the insertion hole 15.

[0047] An arc-shaped groove is also provided on the outer surface of the front end of the insertion rod 4 to facilitate the removal of the insertion rod 4.

[0048] Working principle: When unlocking, the first unlocking method involves inserting the matching electronic key into the lock cylinder. After insertion, the lock cylinder verifies and identifies the key. If the identification fails, the lock cylinder does not supply power to the drive motor 11, thus preventing the lock cylinder from opening. If the identification succeeds, the lock cylinder supplies power to the drive motor 11, causing the drive motor 11 to drive the rotating block 12 to rotate. This causes the groove 13 on the outer surface of the rotating block 12 to contact the ball bearings 10. As the balls 10 roll within the ball bearing channel 9 and the ball bearing groove 24, a gap is created between the balls 10 and the groove 8 on the outer surface of the insertion rod 4, allowing them to disengage. At this point, the insertion rod 4 can be pulled to disengage from the lock block 6, thus unlocking the lock cylinder in the first unlocking method.

[0049] In the second unlocking method, the key rod 38 can be inserted into the insertion hole 15 through the lock hole 3. Both the first fixing rod 16 and the second fixing rod 37 slide on the straight groove 40 until the first fixing rod 16 slides into the annular slot 39. This creates a pathway between the second sensing rod 41 of the key rod 38 and the first sensing rod 19 at the top of the circuit board 18. This causes the second drive motor 29 to rotate the limiting block 30, releasing the fixing of the stop block 31. This allows the first rotating drum 14 and the third rotating drum 20 to rotate relative to each other. At this time, the key, through the fixing of the first fixing rod 16, rotates the second rotating drum 17, which in turn rotates the third rotating drum 20. When the bottom outer surface of the third rotating drum 20 has a locking mechanism... The inner walls of the groove 2 35 and the rotating cylinder groove 33 are provided with a first slot 34. When the movable rod 25 is aligned with the groove 25, the movable rod 25 is inserted into the second slot 35 and disengaged from the first slot 34, allowing the rotating cylinder 14 to rotate on the rotating cylinder groove 33. The groove 3 23 on the outer surface of the rotating cylinder 14 is engaged with the ball 10, allowing the groove 1 8 on the insert rod 4 to disengage from the ball 10, thus completing the key rod 38 to rotate and unlock. At this time, the insert rod 4 is pulled out from the lock block 6 to complete the door opening, and the fixed rod 16 is locked in the annular slot 39. If the key rod 38 is not rotated back to its original position, it cannot be pulled out from the insertion hole 15, thus avoiding the management failure problem caused by non-locking.

[0050] During the rotation of the lock cylinder, the changes in the sensing signals of the first Hall sensor 42 at the bottom of the circuit board 18 and the second magnet 45 inside the rotating cylinder 14 detect whether the lock cylinder is rotating. During the insertion and removal of the locking block 6 by the insertion rod 4, the changes in the sensing signals of the second Hall sensor 44 on the rear bottom of the lock housing 1 and the first magnet 43 on the left side of the locking block 6 detect whether the insertion rod 4 is inserted into the locking block 6. During the opening process, the lock first senses the signal of the first Hall sensor 42 through the rotation of the lock cylinder, and then senses the signal of the second Hall sensor 44 through the removal of the locking block 6 by the insertion rod 4, thus completing the detection of the opening process. During the closing process, the lock first senses the signal of the second Hall sensor 44 through the removal of the locking block 6 by the insertion rod 4, and then senses the signal of the first Hall sensor 42 through the rotation of the lock cylinder. Finally, the lock cylinder is pulled out, thus completing the detection of the door closing process. If only the signal of the first Hall sensor 42 when the lock cylinder rotates is sensed after the door is closed, but the signal of the second Hall sensor 44 when the rod 4 is pulled out of the lock block 6 is not sensed, the rod 4 of the lock cylinder is not inserted, so the lock cylinder cannot rotate and the electronic key cannot be pulled out. This reminds the person to close the lock properly. If the person wants to pull out the electronic key, the rod 4 must be inserted into the lock block 6. After the rod 4 is inserted, the position of the second magnet 45 is detected by the first Hall sensor 42 and the position of the lock block 6 is detected by the second Hall sensor 44. Only then can the lock cylinder rotate and the person pull out the electronic key. This realizes the detection of the lock cylinder being closed properly, thereby preventing the situation of forgetting to close the door. It can detect if the user has forgotten to close the door and remind the user to close the door again, thus strengthening on-site security control.

[0051] The physical interface between the lock cylinder and the key bar 38 is made of stainless steel, which has anti-theft, anti-pry, anti-cutting, anti-mildew, anti-rust, waterproof, dustproof, anti-corrosion and impact-resistant functions.

[0052] The lock cylinder needs to have data recording and data storage protection functions, be able to download data, and ensure that stored information is not lost when there is no working power.

[0053] The lock cylinder has a unique, traceable, and binding identification SN code, which is unique and cannot be copied, and can be read by electronic keys or mobile terminals.
