Description

Technical Field

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

[0002] The Lorentz force is the force exerted on a moving charge in a magnetic field. It refers to the force exerted by a magnetic field on a moving charge. A lock cylinder based on the Lorentz force principle can be powered by an active key, creating a uniform magnetic field inside the cylinder. As the key rotates the cylinder, it causes the charge to cut through the magnetic field, determining whether the lock cylinder is open or closed. This requires not only a correct key shape to rotate the cylinder but also the key to provide the correct electrical energy and magnetic field conditions for the lock cylinder to open normally, increasing the difficulty and complexity of unlocking and improving anti-theft performance.

[0003] The existing technology has the following problems: However, existing Lorentz force security lock cylinders, when faced with violent unlocking, such as prying with a crowbar or breaking with a drill, suffer from deformation of the internal mechanical structure due to stress, causing misalignment of key identification components and resulting in misjudgment by the subsequent identification module. This leads to low stability and anti-theft performance. Furthermore, in today's environment with a wide variety of equipment cabinets and countless matching keys, the poor security also makes it difficult to effectively manage the keys. The management of cabinet keys is difficult and prone to loss or misuse, resulting in high difficulty in key management. Utility Model Content

[0006] Preferably, the locking cylinder includes a lock cylinder housing, and a plurality of locking mechanisms are slidably connected to the rear inner side of the lock cylinder housing, and a circular array of the plurality of locking mechanisms surrounds the outer surface of the lock cylinder rotating assembly.

[0007] Preferably, the lock cylinder rotating assembly includes a lock cylinder rotating shaft. The front end of the lock cylinder rotating shaft is fixedly connected to the rear end of the elastic latch assembly. The rear end of the lock cylinder rotating shaft extends to the outer side of the rear end of the lock cylinder housing. The outer surface of the lock cylinder rotating shaft is provided with a plurality of positioning slots. The plurality of positioning slots are arranged in two parallel groups, and each group of positioning slots is distributed around the outer surface of the lock cylinder rotating shaft. An electromagnetic induction coil is fixedly connected between the two groups of positioning slots on the outer surface of the positioning slots. A lock hole slot is provided at the rear end of the lock cylinder rotating shaft. A plurality of electrical contacts are fixedly connected to the front end of the inner side of the lock hole slot. A radio frequency induction module is embedded and fixedly fixed at the right end of the inner side of the lock hole slot.

[0008] Preferably, the locking mechanism includes a linkage armature, with wedge-shaped locking blocks fixedly connected to both the front and rear ends of the linkage armature via connecting rods. The outer surface of the wedge-shaped locking block is slidably connected to the inside of the lock cylinder housing. The end of the wedge-shaped locking block away from the lock cylinder housing can enter the corresponding positioning slot. A return spring is fixedly connected to the end of the wedge-shaped locking block near the lock cylinder housing, and the end of the return spring away from the wedge-shaped locking block is fixedly connected to the inside of the lock cylinder housing.

[0009] Preferably, each pair of adjacent linkage armatures is movably connected to a suitable connecting rod at both ends, the arc of the linkage armature is the same as that of the lock cylinder rotation axis, and several linkage armatures can simultaneously cover the outer surface of the electromagnetic induction coil.

[0010] Preferably, the elastic latch assembly includes a drive shaft, the rear end of which is fixedly connected to the front end of the lock cylinder rotating shaft, an unlocking gear fixedly connected to the middle of the front end of the drive shaft, a limiting support ring sleeved on the outer surface of the drive shaft, the outer surface of the limiting support ring fixedly connected to the inner side of the lock cylinder housing, a support spring fixedly connected to the outer side of the front end of the unlocking gear, a rotating disk fixedly connected to the front end of the support spring, the front end of the rotating disk rotatably connected to the front end of the inner side of the lock cylinder housing, an intelligent telescopic rod fixedly connected to the middle of the opposite side of the rotating disk and the unlocking gear, an unlocking gear provided on the upper side of the front end of the unlocking gear, an unlocking shaft fixedly connected to the front end of the unlocking gear, the front end of the unlocking shaft extending to the outer side of the front end of the lock cylinder housing, the outer surface of the unlocking shaft rotatably connected to the inside of the lock cylinder housing, a fixed latch fixedly connected to the front end of the unlocking shaft, and the unlocking gear intermittently meshing with the unlocking gear.

[0012] This invention provides a resilient locking tongue assembly and a locking mechanism. Compared with the prior art, it has the following advantages: 1. This security lock cylinder identification structure uses electrical contacts and an electromagnetic induction coil to attract a linkage armature the moment an active key comes into contact with it. This causes the wedge-shaped locking block to lock the cylinder's rotating shaft. Only when the radio frequency sensing module detects that the IC card on the active key matches the lock cylinder's permissions will the power supply to the electromagnetic induction coil be disconnected, releasing the lock cylinder's rotating shaft from the lock. This ensures that each unlocking requires authorization verification, improving security. Furthermore, it allows for unified management of key ownership permissions through a backend system, enabling one key to open multiple locks with different permissions, thus avoiding the need to carry a large number of keys.

[0013] 2. This security lock cylinder identification structure, through the design that the unlocking gear and the non-plane unlocking gear are not on the same plane, allows the lock cylinder to only spin freely when no active key is inserted. In the face of violent unlocking operations such as prying, it can effectively prevent the internal structure of the lock cylinder from being damaged, avoid misalignment of key identification components, reduce the probability of misjudgment by the identification module, and greatly improve the stability and anti-theft of the lock cylinder.

[0016] 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.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a security lock cylinder identification structure, including a locking lock cylinder 2, a lock cylinder rotating assembly 4 is provided in the middle of the inner side of the locking lock cylinder 2, the rear end of the lock cylinder rotating assembly 4 extends to the outer side of the rear end of the locking lock cylinder 2, an elastic lock tongue assembly 1 is provided in the front side of the inner side of the locking lock cylinder 2, and a lock cylinder head 3 is provided in the outer side of the rear end of the locking lock cylinder 2.

[0018] When using the security lock cylinder identification structure, the active key is inserted into the corresponding position of the lock cylinder rotating assembly 4. At this time, the lock cylinder performs an access verification. If the key's access is correct, the locked lock cylinder 2 will unlock, allowing the lock cylinder rotating assembly 4 to rotate under external force. Simultaneously, correct access can push the elastic bolt assembly 1, causing the fixed bolt 16 to rotate, thus unlocking the lock. If the key's access is incorrect, the locked lock cylinder 2 will fix the lock cylinder rotating assembly 4, preventing it from rotating and thus preventing the lock from being opened.

[0019] Please see Figure 2 The locking cylinder 2 includes a lock cylinder housing 21. Several locking mechanisms 22 are slidably connected to the rear inner side of the lock cylinder housing 21. The several locking mechanisms 22 are arranged in a circular array around the outer surface of the lock cylinder rotating assembly 4. When an unlocking operation is performed, if an authorized active key is inserted, the several locking mechanisms 22 surrounding the outer surface of the lock cylinder rotating assembly 4 will be unlocked due to the internal mechanism, allowing the lock cylinder rotating assembly 4 to rotate smoothly, thereby driving other related components to complete the unlocking action. If the key inserted does not meet the authorization requirements, the locking mechanisms 22 will remain locked, restricting the rotation of the lock cylinder rotating assembly 4, and the lock cannot be opened, thereby realizing the control of the lock cylinder rotation and the security protection function.

[0020] Please see Figure 3The lock cylinder rotating assembly 4 includes a lock cylinder rotating shaft 41. The front end of the lock cylinder rotating shaft 41 is fixedly connected to the rear end of the elastic lock tongue assembly 1. The rear end of the lock cylinder rotating shaft 41 extends to the outer side of the rear end of the lock cylinder housing 21. Several positioning slots 42 are provided on the outer surface of the lock cylinder rotating shaft 41. The several positioning slots 42 are arranged in two parallel groups, and each group of positioning slots 42 is distributed around the outer surface of the lock cylinder rotating shaft 41. An electromagnetic induction coil 44 is fixedly connected between the two groups of positioning slots 42 on the outer surface of the positioning slots 42. A lock hole slot 46 is provided at the rear end of the lock cylinder rotating shaft 41. Several electrical contacts 43 are fixedly connected to the front end of the inner side of the lock hole slot 46. A radio frequency sensing module 45 is embedded and fixedly fixed at the right end of the inner side of the lock hole slot 46.

[0021] An active key is inserted into the keyhole slot 46. At this time, the power contact 43 contacts the key and is energized, generating a strong magnetic field in the electromagnetic induction coil 44. After the key is inserted, the radio frequency sensing module 45 performs key access control. If the key access is correct, the radio frequency sensing module 45 controls the magnetic field around the electromagnetic induction coil 44 to change accordingly, causing other cooperating components to operate, releasing the restriction on the lock cylinder rotation shaft 41, allowing the lock cylinder rotation shaft 41 to rotate and drive the elastic bolt assembly 1 connected to the front end to operate, thus unlocking the lock. If the key access is incorrect, the lock cylinder rotation shaft 41 remains locked and cannot rotate, thus preventing the lock from opening.

[0022] The radio frequency sensing module 45 can intelligently identify the IC card's permissions and intelligently sense the surrounding magnetic field state through radio frequency signals in order to control other components. The power transmission contact 43 can transmit power from the key to the entire lock cylinder through contact with the active key. The electromagnetic induction coil 44 can generate a strong magnetic field when energized. These are all existing technologies and will not be explained here.

[0023] Please see Figure 4 The locking mechanism 22 includes a linkage armature 221. Both the front and rear ends of the linkage armature 221 are fixedly connected to wedge-shaped locking blocks 224 via connecting rods. The outer surface of the wedge-shaped locking blocks 224 is slidably connected to the inside of the lock cylinder housing 21. The end of the wedge-shaped locking blocks 224 away from the lock cylinder housing 21 can enter the corresponding positioning slot 42. A return spring 223 is fixedly connected to the end of the wedge-shaped locking blocks 224 near the lock cylinder housing 21. The end of the return spring 223 away from the wedge-shaped locking blocks 224 is fixedly connected to the inside of the lock cylinder housing 21.

[0024] Please see Figure 4 Each pair of adjacent linkage armatures 221 are movably connected to a suitable connecting rod 222 at their front and rear ends. The arc of the linkage armature 221 is the same as that of the lock cylinder rotation shaft 41. Several linkage armatures 221 can simultaneously cover the outer surface of the electromagnetic induction coil 44.

[0025] When a key is inserted into the lock cylinder, the electromagnetic induction coil 44 is energized, generating a magnetic field that attracts the linkage armature 221. During this attraction, the linkage armature 221 drives the wedge-shaped locking block 224 to slide within the lock cylinder housing 21 via a connecting rod. This causes the wedge-shaped locking block 224 to enter the corresponding positioning slot 42, locking the lock cylinder rotation shaft 41. If the key authentication is successful, the radio frequency sensing module 45 cuts off the power supply to the electromagnetic induction coil 44. After the magnetic field disappears, the reset spring 223 pushes the wedge-shaped locking block 224 back to its initial position, releasing the lock cylinder rotation shaft 41, allowing it to rotate. If the authentication fails, the lock cylinder rotation assembly 4 remains locked to prevent unauthorized unlocking.

[0026] Please see Figure 5 The elastic latch assembly 1 includes a drive shaft 12, the rear end of which is fixedly connected to the front end of the lock cylinder rotating shaft 41. An unlocking gear 13 is fixedly connected to the middle of the front end of the drive shaft 12. A limiting support ring 11 is sleeved on the outer surface of the drive shaft 12. The outer surface of the limiting support ring 11 is fixedly connected to the inner side of the lock cylinder housing 21. A support spring 18 is fixedly connected to the outer side of the front end of the unlocking gear 13. A rotating disk 17 is fixedly connected to the front end of the support spring 18. The front end of the rotating disk 17 is rotatably connected to the front end of the inner side of the lock cylinder housing 21. An intelligent telescopic rod 19 is fixedly connected to the middle of the opposite side of the rotating disk 17 and the unlocking gear 13. An unlocking gear 14 is provided on the upper side of the front end of the unlocking gear 13. An unlocking shaft 15 is fixedly connected to the front end of the unlocking gear 14. The front end of the unlocking shaft 15 extends to the outer side of the front end of the lock cylinder housing 21. The outer surface of the unlocking shaft 15 is rotatably connected to the inside of the lock cylinder housing 21. A fixed latch 16 is fixedly connected to the front end of the unlocking shaft 15. The unlocking gear 14 can intermittently mesh with the unlocking gear 13.

[0027] Please see Figure 5 The outer one-third of the surface of the unlocking gear 13 is set as teeth. The unlocking gear 13 only meshes with the unlocking gear 14 through the teeth. The number of teeth of the unlocking gear 13 is half that of the unlocking gear 14. The unlocking gear 13 is not on the same plane when it is not meshing with the unlocking gear 14.

[0028] When no active key is inserted, there is no power inside the lock cylinder. At this time, the intelligent telescopic rod 19 remains in an extended state and cannot be retracted. The unlocking gear 13 and the unlocking gear 14 are on different planes and are not meshed. Forceful unlocking by external force can only cause the lock cylinder rotating shaft 41 to drive the unlocking gear 13, the support spring 18, the rotating disk 17, and the intelligent telescopic rod 19 to rotate freely, preventing contact with the unlocking gear 14. The effect of adapting to the rotation of external force is transformed into ineffective work, thereby avoiding forceful unlocking. When an active key is inserted, the locking mechanism 22 first locks the lock cylinder rotating shaft 41. After the radio frequency sensing module 45 successfully recognizes the authorization, the lock cylinder rotating shaft 41 can rotate. At the same time, the radio frequency sensing module 45 can unlock the smart telescopic rod 19 so that it becomes retractable. At this time, the lock cylinder rotating shaft 41 is pushed forward, so that the moving shaft 12 drives the unlocking gear 13 to mesh with the unlocking gear 14 during rotation. The limiting support ring 11 can prevent the unlocking gear 13 from being pushed too far. After the lock cylinder rotating shaft 41 is fully pushed forward, the unlocking gear 13 is exactly on the same plane as the unlocking gear 14. Since the unlocking gear 13 and the unlocking gear 14 have overlapping parts, the unlocking gear 13 can only move forward when the two can mesh. The meshing unlocking gear 13 will do work on the unlocking gear 14 under the rotation of the unlocking gear 14, thereby driving the fixed lock tongue 16 to rotate to perform the unlocking operation. The tooth number relationship between the unlocking gear 13 and the unlocking gear 14 is just enough to make the fixed lock tongue 16 only able to rotate 180 degrees, ensuring the stability of unlocking. The intelligent telescopic rod 19 can be controlled by the radio frequency sensing module 45. It can only release itself from the fixed state when the radio frequency sensing module 45 recognizes the magnetic field and the authorization is met. After the key is pulled out, the intelligent telescopic rod 19 and the support spring 18 push the unlocking gear 13 to retract and disengage from the unlocking gear 14. The intelligent telescopic rod 19 then remains in the fixed state. This is existing technology and will not be explained here.

[0029] Please see Figure 1-5 At work, When the active key is inserted into the lock hole slot 46 at the rear end of the lock cylinder rotating assembly 4, the power contact 43 is energized, the electromagnetic induction coil 44 generates a magnetic field, and the radio frequency sensing module 45 performs authorization identification on the IC card on the key. If the authorization matches, the electromagnetic induction coil 44 is de-energized, and the wedge-shaped locking block 224 disengages from the positioning slot 42 under the action of the return spring 223, unlocking the lock cylinder rotating shaft 41. At the same time, the intelligent telescopic rod 19 is unlocked and becomes retractable, rotating and pushing the lock cylinder rotating shaft 41, driving the transmission shaft to make the unlocking gear 13 mesh with the unlocking gear 14, thereby driving the unlocking shaft 15 and the fixed lock tongue 16 to rotate, realizing unlocking. After the key is pulled out, the intelligent telescopic rod 19 and the support spring 18 push the unlocking gear 13 back, disengaging it from the unlocking gear 14, the intelligent telescopic rod 19 returns to the fixed state, and the lock cylinder returns to the locking preparation state.
