Description

Technical Field

[0001] The present invention relates to the technical field of unlocking devices, and in particular to an unlocking mechanism and an unlocking key. Background Art

[0002] Computer keys hold an irreplaceable position in the field of accidental access security. As these devices have evolved, their functions and types have diversified. The unlocking mechanism directly linked to the unlocking process of computer keys is the key element. In this field, the key element of the unlocking mechanism is the authorization mechanism.

[0003] Existing computer key authorization mechanisms primarily rely on direct drives such as magnetic and solenoids. These direct drives, where the driving element is in direct and continuous contact with the driven element, offer low security and are easily cracked. Malfunctioning of the driving element or external interference can easily lead to misauthorization issues within the unlocking mechanism.

[0004] There is currently an authorization mechanism and computer key with integrated automatic blade extension and solenoid indirect authorization. The key blade is automatically extended and retracted by a motor screw. When in operation, the key blade pops out to the working position and the authorization mechanism is connected; when not in operation, the key blade retracts into the key and the authorization mechanism is disconnected. After the computer key is inserted into the corresponding lock, the authorization is approved, and the solenoid drives the authorization mechanism to the authorized position to unlock the corresponding lock. If the authorization is not approved, the authorization mechanism will not operate. Although the indirect authorization mechanism has a certain degree of security and can effectively prevent illegal unlocking of the computer key, the electromagnetic characteristics of the solenoid, which adsorbs when powered on and retracts when powered off, make it easy to cause impact authorization, and therefore there is still a certain security risk.

When the unlocking piece assembly is in the retracted position, the magnetic component is outside the swing range of the authorization lever, and the authorization component cannot drive the authorization magnetic part to move.

[0007] Furthermore, the authorization component also includes an authorization screw, which is driven by the authorization motor and has screw threads. The authorization lever has meshing teeth, and the screw threads engage with the meshing teeth. The authorization motor drives the authorization lever to swing through the authorization screw.

DETAILED DESCRIPTION

[0037] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0039] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0040] In order to solve the problem of poor security of the authorization mechanism of the computer key in the prior art, the present invention provides an unlocking mechanism and an unlocking key.

[0041] like Figures 1 to 8 The unlocking mechanism shown in the figure includes a shell 10, an unlocking piece assembly 20, a screw 30, a lock piece driving member 40, a magnetic assembly 50 and an authorization assembly 60. The unlocking piece assembly 20 is telescopically arranged on the shell 10 and has a working position extending out of the shell 10 and a retracted position retracted into the shell 10; the screw 30 is threadedly matched with the unlocking piece assembly 20 and can drive the unlocking piece assembly 20 to move between the working position and the retracted position; the lock piece driving member 40 is drivingly connected to the screw 30 and can drive the screw 30 to rotate to drive the unlocking piece assembly 20 to move between the working position and the retracted position; the magnetic assembly 50 is movably arranged in the unlocking piece assembly 20 and has an authorization magnetic member 51 that cooperates with the lock core, and the authorization magnetic member 51 can The authorization component 60 includes an authorization motor 61 and an authorization lever 62, and the authorization lever 62 is driven by the authorization motor 61. The authorization lever 62 is swingably arranged in the housing 10 and intermittently cooperates with the magnetic component 50. When the unlocking piece assembly 20 is in the working position, the magnetic component 50 is within the swing range of the authorization lever 62, and the authorization motor 61 drives the authorization lever 62 to swing, and the authorization lever 62 drives the authorization magnetic part 51 to move between the authorized position and the unauthorized position. When the unlocking piece assembly 20 is in the retracted position, the magnetic component 50 is outside the swing range of the authorization lever 62, and the authorization component 60 cannot drive the authorization magnetic part 51 to move.

[0042] This embodiment configures the authorization assembly 60 to utilize an authorization motor 61 in conjunction with an authorization lever 62. Compared to conventional solenoid-driven methods, the motor-driven method provides more accurate and convenient control of the movement stroke, effectively preventing the unlocking blade from being illegally unlocked when not in the operating position. This solves the problem of solenoids being susceptible to impact authorization due to their structural characteristics, enhancing the security of the authorization mechanism. Furthermore, the overall structure is compact and easy to control, facilitating product miniaturization. The specific operation of the unlocking mechanism is as follows: when the unlocking mechanism is locked, the unlocking plate assembly 20 is in the retracted position, the authorization assembly 60 is unauthorized, and the authorization lever 62 does not affect the magnetic assembly 50. The two are independent of each other, and the magnetic assembly 50 remains in the unauthorized position, thereby preventing interference from external and internal actuating components and preventing the authorization assembly 60 from malfunctioning due to malfunction. Simultaneously, since the locking plate driver 40 stops rotating, the unlocking plate assembly 20 is self-locking, and external forces cannot drive the unlocking plate assembly 20 to move. When the unlocking mechanism is unlocked, the lock plate driving member 40 drives the screw 30 to rotate, and the screw 30 drives the unlocking plate assembly 20 to move to the working position. After the unlocking plate assembly 20 moves to the working position, the authorization lever 62 cooperates with the magnetic assembly 50 for transmission. At this time, the authorization motor 61 drives the authorization lever 62 to swing, and the authorization lever 62 can move the magnetic assembly 50, so that the authorization magnetic member 51 moves from the unauthorized position to the authorized position, thereby realizing the unlocking of the authorization pin of the lock cylinder.

[0043] like Figures 2 to 8 As shown, the authorization assembly 60 also includes an authorization screw 63, which has a non-circular hole. Correspondingly, the authorization motor 61 has an output shaft of matching shape, which extends into the non-circular hole, so that the authorization screw 63 is connected to the authorization motor 61, and the authorization motor 61 can drive the authorization screw 63 to rotate synchronously. The outer peripheral surface of the authorization screw 63 has a screw thread 631, and correspondingly, the end of the authorization lever 62 that does not cooperate with the magnetic assembly 50 has a meshing tooth 621, as shown in FIG. Figure 9 and Figure 10 As shown, the screw thread 631 meshes with the meshing teeth 621. Thus, when the authorization motor 61 drives the authorization screw 63 to rotate, the authorization screw 63 can drive the authorization lever 62 to swing through the meshing of the screw thread 631 and the meshing teeth 621, thereby driving the magnetic assembly 50. Of course, the driving cooperation between the authorization motor 61 and the authorization lever 62 is not limited to the above-mentioned configuration, and other structural components can also be used to achieve the driving cooperation between the two.

[0044] In this embodiment, the authorization component 60 further includes a mounting bracket 64, such as Figure 11As shown, the mounting bracket 64 is cylindrical and fixedly mounted within the housing 10. The mounting bracket 64 defines a mounting cavity 641, which accommodates at least a portion of the authorization motor 61 and the authorization screw 63, thereby securing the authorization motor 61. A notch is defined in the sidewall of the mounting cavity 641, distal from the opening through which the authorization motor 61 extends. The meshing teeth 621 of the authorization lever 62 can extend through the notch into the mounting cavity 641, thereby meshing with the screw teeth 631 and achieving transmission. The mounting bracket 64 also has side ears 642 on either side of the notch. Each ear has a through-hole. The authorization lever 62 has a hinge hole 623. A rotating shaft extends through the through-holes of the ear 642 and the hinge hole 623 of the authorization lever 62, thereby swingably connecting the authorization lever 62 to the mounting bracket 64.

[0045] The meshing teeth 621 of the authorization lever 62 of this embodiment form a gear-like structure, and its central axis coincides with the rotation axis of the authorization lever 62. In this way, when the authorization screw 63 rotates, it can drive the authorization lever 62 to rotate around the rotation axis.

[0046] like Figure 9 As shown, the end of the authorization lever 62 away from the authorization motor 61, that is, the end away from the meshing teeth 621, has a swing column 622. The swing column 622 is cylindrical, and its axis is parallel to the rotation axis of the authorization lever 62. When the authorization lever 62 swings, the circumferential side surface of the swing column 622 squeezes and moves the magnetic assembly 50, causing the magnetic assembly 50 to move to the authorization position.

[0047] like Figures 4 to 6 as well as Figure 9 As shown, the unlocking mechanism further includes an authorization detection member 70 and an authorization sensing member. The authorization detection member 70 is made of magnetic steel. A detection hole 624 is axially defined in the swing column 622. The authorization detection member 70 is mounted within the detection hole 624 so as to swing with the swing column 622. The authorization sensing member, which can be a reed switch or a Hall effect element, is fixedly mounted within the housing 10 and is capable of sensing the position of the authorization detection member 70. By detecting the position of the authorization detection member 70, the position of the authorization lever 62 can be determined, thereby determining the authorization status of the authorization assembly 60 and, in turn, the status of the magnetic assembly 50.

[0048] like Figure 1 、 Figure 12 and Figure 14As shown, the unlocking piece assembly 20 includes an unlocking piece 21 and a slider 22. The unlocking piece 21 has a receiving hole 211. The receiving hole 211 is opened along the length direction of the unlocking piece 21, that is, the movement direction of the unlocking piece 21. The magnetic component 50 is movably arranged in the receiving hole 211. By changing the position, the matching relationship between the magnetic component 50 and the authorization pin of the lock cylinder can be changed, thereby unlocking or locking the authorization pin; the slider 22 is connected to the unlocking piece 21, and the slider 22 is located at the end of the unlocking piece 21 away from the housing 10. A mounting hole 222 is opened on the slider 22, and one end of the unlocking piece 21 is set in the mounting hole 222. The side walls of the mounting hole 222 and the end of the unlocking piece 21 are both provided with a through hole or a through groove, and a pin is passed through the through hole or the through groove, thereby connecting the unlocking piece 21 and the slider 22 together, so that the slider 22 and the unlocking piece 21 slide synchronously, and the slider 22 also has a threaded hole 221, and the screw 30 is passed through the threaded hole 221 and cooperates with the inner wall thread of the threaded hole 221. In this way, when the screw 30 rotates under the drive of the locking piece driving member 40, the screw 30 can drive the slider 22 and the unlocking piece 21 to move through the cooperation with the threaded hole 221, so that the unlocking piece 21 can be extended or retracted into the shell 10.

[0049] like Figures 2 to 6 As shown, the unlocking mechanism of this embodiment further includes a guide rod 80, the length direction of which is the same as the direction of movement of the unlocking piece 21. The slider 22 has a through-hole, through which the guide rod 80 is inserted, and the slider 22 slides along the length direction of the guide rod 80. In this embodiment, two guide rods 80 are provided, and two through-holes are defined on the slider 22, and the two guide rods 80 are respectively inserted into one through-hole. The provision of the guide rods 80 enables the slider 22 and the unlocking piece 21 to slide in a predetermined manner, preventing the screw 30 from driving the slider 22 and the unlocking piece 21 to rotate, thereby ensuring the reliability of the movement of the unlocking piece assembly 20.

[0050] like Figure 2 As shown, the unlocking mechanism further includes a transmission assembly 90, through which the locking plate driver 40 is drivenly connected to the screw 30. The transmission assembly 90 is at least one of a gear set, a worm gear set, a belt set, and a chain set. This embodiment uses a gear set as the transmission assembly 90, specifically comprising a drive gear, an idler gear, and a transmission gear. The drive gear is drivenly connected to the output shaft of the locking plate driver 40 via a D-shaped opening or other structure, and the transmission gear is also drivenly connected to the screw 30 via a D-shaped opening or other structure. One or more idler gears are provided between the drive gear and the transmission gear as needed. The aforementioned gear set enables the locking plate driver 40 to drive the screw 30 to rotate.

[0051] like Figure 2As shown, the unlocking mechanism of this embodiment also includes a sleeve 100, which is sleeved on the end of the screw 30, and the sleeves 100 are installed at both ends of the screw 30. The sleeves 100 at both ends are respectively accommodated in the unlocking piece assembly 20 and the transmission assembly 90, thereby limiting the installation position of the screw 30 and ensuring that the installation position of the screw 30 is accurate and reliable.

[0052] like Figure 2 and Figure 13 As shown, the magnetic component 50 of this embodiment also includes a push rod 52, at least a part of the push rod 52 is movably arranged in the accommodating hole 211 of the unlocking piece 21, and the push rod 52 is fixedly installed with the authorization magnetic part 51 at one end thereof that is inserted into the lock core close to the unlocking piece 21, and the other end can extend out of the accommodating hole 211 so as to be squeezed and matched with the authorization dial rod 62, thereby achieving the effect of the authorization dial rod 62 squeezing and toggling the push rod 52 to drive the authorization magnetic part 51 to move.

[0053] The push rod 52 of this embodiment includes a mounting portion 521, a limiting slide 523, and a driving arm 522 connected in sequence. The authorization magnetic member 51 is mounted on the mounting portion 521, thereby achieving the installation and fixation of the authorization magnetic member 51. The unlocking mechanism also includes a limiting pin, which is inserted into the unlocking piece 21 and the limiting slide 523, thereby controlling the range of movement of the push rod 52 in the accommodating hole 211, and preventing the push rod 52 from escaping from the unlocking piece 21 or moving too far. At least a portion of the driving arm 522 extends out of the accommodating hole 211. The driving arm 522 is the part that directly cooperates with the authorization lever 62. It cooperates with the authorization lever 62 in a linkage manner. The authorization lever 62 drives the authorization magnetic member 51 to move by squeezing the driving arm 522.

[0054] like Figure 7 and Figure 8 As shown, the unlocking mechanism also includes a reset member 53, which is a spring and is sleeved on the push rod 52. One end of the reset member 53 abuts against the authorized magnetic member 51 or the push rod 52, and the other end abuts against the unlocking piece 21, thereby providing the push rod 52 with a reset force to drive the authorized magnetic member 51 to move to the unauthorized position, so that the magnetic component 50 always remains in the unauthorized position when it is not driven by the authorization component 60.

[0055] like Figure 2As shown, the unlocking mechanism of this embodiment further includes a control switch 110, which is electrically connected to the lock plate driver 40 and the authorization assembly 60. The slider 22 of the unlocking plate assembly 20 has a trigger protrusion 223 on its side. The trigger end of the control switch 110 is located in the motion path of the trigger protrusion 223. The trigger protrusion 223 can cooperate with the trigger end to control the motion range of the unlocking plate assembly 20. When the unlocking plate assembly 20 moves to the working position or the retracted position, the trigger protrusion 223 triggers the trigger end, and the control switch 110 controls the lock plate driver 40 to stop. One or two control switches 110 can be provided as needed. One control switch 110 can control the movement of the unlocking plate assembly 20 in only one direction, or one control switch 110 can have two trigger ends to control the movement of the unlocking plate assembly 20 in both directions. Alternatively, two control switches 110 can be provided to control the movement of the unlocking plate assembly 20 in both directions.

[0056] Optionally, the unlocking mechanism also includes a lock detection component 120 and a coil 130. The lock detection component 120 is a Hall element, which is located at one end of the shell 10 close to the lock core, and can cooperate with the magnet in the lock core during the unlocking process of the unlocking mechanism, thereby determining the open or closed lock state of the lock core by detecting the change in magnetic flux; the coil 130 is located at one end of the shell 10 close to the lock core, and can supply power, collect codes, and communicate with the lock core to realize functions such as confirming the identity of the lock core and supplying power to the lock core.

[0057] In addition, the unlocking mechanism may also be provided with a control assembly 140. The control assembly 140 is electrically connected to the lock plate driver 40, the authorization motor 61, the control switch 110, the lock detection component 120, the coil 130, and other energized components. The control assembly 140 is capable of controlling the operation of each component and coordinating the movement of each component through the control system. For example, when the unlocking mechanism is inserted into the lock cylinder, the coil 130 authenticates the lock cylinder. Once the authentication is successful, the control assembly 140 controls the authorization assembly 60 to drive the magnetic assembly 50 to unlock the authorization pin in the lock cylinder. After receiving the unlock or lock command, the control assembly 140 controls the lock plate driver 40 to operate, thereby changing the position of the unlocking plate assembly 20, and so on.

[0058] Optionally, the housing 10 of this embodiment is formed by docking a plurality of separately provided sub-components, and the sub-components are fixed together by screws, thereby facilitating the installation of the components into the housing 10. The housing 10 can form one or more semi-enclosed or fully enclosed accommodating areas as needed to install the components into the accommodating areas as needed.

[0059] It should be noted that, in the above embodiments, a plurality refers to at least two.

[0060] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0061] 1. Solve the problem of poor security of the authorization agency of computer keys in the prior art;

[0062] 2. Compared with the traditional solenoid drive method, the motor drive method is more accurate and convenient in controlling the motion stroke, effectively preventing the unlocking blade from being illegally unlocked when it is not in the working position, solving the problem of impact authorization caused by the structural characteristics of the solenoid, and increasing the security of the authorization mechanism;

[0063] 3. The overall structure is compact and easy to control, which is conducive to product miniaturization;

[0064] 4. When locked, the authorization lever does not affect the magnetic component. There is no correlation between the two. The magnetic component remains in the unauthorized position, thereby avoiding interference from external and internal actuators and preventing the authorization component from failing due to malfunction of the driver.

[0065] 5. The authorization action is reliable, which prevents the unlocking key from becoming a master key due to unauthorized unlocking.

[0066] 6. Use contact or non-contact detection methods to monitor the authorization status and increase the security of the authorization component.

[0067] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
