Description

Technical Field

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

[0002] In the field of anti-error security, computer keys have an irreplaceable position. The unlocking mechanism is directly related to the unlocking process of the computer key; and in order to avoid the occurrence of operator error such as accidental unlocking and locking, the unlocking mechanism generally adds an unlocking lever component and an authorization component to meet relevant requirements.

[0003] Specifically, the unlocking rod of the unlocking rod assembly in the computer key is mostly in the shape of a raised column, sheet or strip, and is provided with a tooth pattern that matches the lock core of the lock, so as to play the first identification role in preventing misoperation. In addition, the locking principle of the unlocking mechanism currently on the market is mainly rotation locking, which first uses the authorization component set in the unlocking mechanism to identify and authorize the identity of the lock, and then switches the locking state and unlocking state of the unlocking mechanism according to the authorization result, so as to play the second identification role in preventing misoperation.

[0004] In actual applications, the unlocking rod assembly in computer keys mostly adopts a fixed structure, that is, the unlocking rod cannot be retracted inside the computer key, which easily exposes the unlocking rod, causing wear and even damage due to falling or collision. In order to prevent the unlocking rod of the computer key from being damaged when it falls, some manufacturers have designed computer keys that use a folding method to retract the unlocking rod, but the folding method in the above design mostly uses a mechanical pressing operation, which is also easy to cause the unlocking rod to pop out due to misoperation, which is not conducive to the protection of the unlocking rod. Summary of the invention

[0016] A connecting groove is provided at the bottom of the mounting portion, the output shaft is threadedly connected to the connecting groove, and the output shaft is rotatably arranged inside the accommodating groove through the telescopic driver, and the rotation of the output shaft drives the unlocking rod to move axially relative to the fixing seat.

DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] The present technical solution provides an unlocking mechanism, comprising a fixed seat 1, an unlocking rod 2, a sleeve 3, an unlocking sleeve 4 and a telescopic drive assembly 9; the mounting portion 21 of the unlocking rod 2 is mounted on the fixed seat 1, the sleeve 3 is sleeved on the outside of the unlocking rod 2, the unlocking sleeve 4 is mounted on the fixed seat 1, and the sleeve 3 is rotatably arranged between the unlocking sleeve 4 and the unlocking rod 2; the telescopic drive assembly 9 is connected to the unlocking rod 2, the unlocking rod 2 can move axially relative to the fixed seat 1 through the telescopic drive assembly 9, and the unlocking portion 22 of the unlocking rod 2 can extend and retract in the sleeve 3; the top of the sleeve 3 is provided with a matching portion 31, and the matching portion 31 protrudes from the unlocking sleeve 4;

[0035] It also includes an authorization element 5 and a limiter 6, and the limiter 6 is electrically connected to the authorization element 5; the authorization element 5 is installed inside the unlocking sleeve 4, and the limiter 6 is installed on the fixing seat 1, and the limiter 6 includes at least an authorized state and an unauthorized state; when the limiter 6 is in the unauthorized state, the sleeve 3 and the unlocking sleeve 4 are relatively stationary; when the limiter 6 is in the authorized state, the sleeve 3 rotates relative to the unlocking sleeve 4.

[0036] In order to solve the problem in the prior art that the unlocking rod is easily worn due to being exposed, the present technical solution proposes an unlocking mechanism, which can help ensure the stable extension and retraction of the unlocking rod while ensuring the normal implementation of the authorization function of the unlocking mechanism.

[0037] Specifically, Figure 1-5 As shown, the unlocking mechanism of the present invention comprises a fixed seat 1, an unlocking rod 2, a sleeve 3 and an unlocking sleeve 4 which are connected in sequence, and the sleeve 3 is rotatably arranged between the unlocking sleeve 4 and the unlocking rod 2; in addition, a matching portion 31 matching with the lock is arranged on the top of the sleeve 3, and the matching portion 31 protrudes from the unlocking sleeve 4. In some embodiments, as Figure 6 As shown, the matching portion 31 of the sleeve 3 is a groove, and the keyhole wall of the lock that matches it is protruding with a convex strip. When the unlocking rod 2 is inserted into the keyhole of the lock, the convex strip is matched and installed in the groove, and the state of whether the sleeve 3 can rotate relative to the unlocking sleeve 4 is switched according to the authorization result.

[0038] In order to avoid the situation that the unlocking rod is ejected due to misoperation in the existing unlocking mechanism that uses mechanical pressing to retract the foldable unlocking rod, the unlocking mechanism of this scheme proposes a way to hide the unlocking rod, install the mounting portion 21 of the unlocking rod 2 on the fixed seat 1, and connect the telescopic driving assembly 9 to the unlocking rod 2, so that the unlocking rod 2 can move axially relative to the fixed seat 1 through the telescopic driving assembly 9, and the unlocking portion 22 of the unlocking rod 2 can extend and retract in the sleeve 3. Since the extension and retraction of the unlocking rod 2 in this scheme are driven by the telescopic driving assembly 9, it is more conducive to reducing the probability of misoperation compared with the hiding method of manual pressing operation in the prior art; and since the unlocking rod of this scheme extends and retracts inside the sleeve in a "displacement telescopic" manner, compared with the prior art that extends and retracts inside the computer key in a "folding telescopic" manner, the avoidance area reserved on the outside of the computer key is smaller, which can effectively avoid dust accumulation in the avoidance position and cause telescopic mud jam. It should be noted that the telescopic driving assembly 9 in this scheme can be installed on the fixed seat 1, or it can be set close to the fixed seat 1, which is not limited here.

[0039] In addition, in order to prevent the telescopic structure of the unlocking rod 2 from affecting the authorization function of the unlocking mechanism, the present solution also optimizes the relevant structure of the authorization mechanism to ensure that the authorization function of the unlocking mechanism is normally realized. Specifically, the authorization element 5 (such as a code reading device for reading the identity information of the lock code chip) is installed inside the unlocking sleeve 4, so that when the unlocking rod 2 is inserted into the keyhole of the lock, the authorization element 5 reads the information of the lock code chip; then the limiter 6 electrically connected to the authorization element 5 is installed on the fixing seat 1, and the rotation of the sleeve 3 relative to the unlocking sleeve 4 is limited by the limiter 6, so that the state of whether the sleeve 3 can rotate relative to the unlocking sleeve 4 is switched according to the authorization result, and the structure is simple and compact.

[0040] When the unlocking mechanism is not in use, the unlocking portion 22 of the unlocking lever 2 in this solution is retracted into the sleeve 3, such as Figure 4 When the unlocking mechanism is needed to open the lock, the unlocking process is as follows: (1) The unlocking rod 2 is driven to move axially relative to the fixed seat 1 by the telescopic drive assembly 9, and the unlocking portion 22 of the unlocking rod 2 is extended out of the sleeve 3, as shown in FIG. Figure 4 (2) inserting the unlocking part 22 into the lock cylinder of the lock, and reading the identity information of the lock code chip through the authorization element 5; when the identity information read by the authorization element 5 does not match the identity information of the corresponding lock code chip, the identification information is sent to the limiter 6, and the limiter 6 is placed in the unauthorized state, such as Figure 5In state (a), the sleeve 3 and the unlocking sleeve 4 are relatively still, and due to the setting of the matching portion 31, the unlocking mechanism cannot be rotated to unlock; when the identity information read by the authorization element 5 matches the identity information of the corresponding lock code chip, the identification information is sent to the limiter 6, and the limiter 6 is placed in the authorization state, as shown in FIG. Figure 5 As shown in the middle state (b), the sleeve 3 rotates relative to the unlocking sleeve 4. When the unlocking mechanism is rotated, the lock core can be driven to rotate through the unlocking portion 22, thereby achieving unlocking.

[0041] Further, the fixing seat 1 has a receiving groove 11 formed inside, and the receiving groove 11 is used to receive the unlocking rod 2, and the unlocking rod 2 moves along the extending direction of the receiving groove 11;

[0042] It also includes a telescopic detector 7, which is arranged on the side wall of the accommodating groove 11, and the detection end of the telescopic detector 7 faces the inside of the accommodating groove 11. The telescopic detector 7 is used to detect the telescopic condition of the unlocking rod 2.

[0043] In a preferred embodiment of the present technical solution, in order to facilitate the operator to understand the extension and retraction status of the unlocking rod 2 so as to improve the controllability of the unlocking mechanism, the present solution also adds a telescopic position detector 7 in the unlocking mechanism, and makes the axial movement of the unlocking rod 2 act on the detection end of the telescopic position detector 7, so that the extension and retraction status of the unlocking rod 2 can be quickly obtained.

[0044] In some embodiments, the telescopic detector 7 of the present solution can be an infrared detector or a photoelectric switch. Specifically, the transmitting end and the receiving end of the infrared detector (or the photoelectric switch) are respectively arranged on both sides of the inner wall of the accommodating groove 11. When the unlocking rod 2 is extended out of the sleeve 3, the transmitting end and the receiving end of the infrared detector (or the photoelectric switch) are connected to each other. When the unlocking rod 2 is retracted in the sleeve 3, the transmitting end and the receiving end of the infrared detector (or the photoelectric switch) are not connected under the shielding of the mounting portion 21, so that the telescopic condition of the unlocking rod 2 can be known through the connection state of the transmitting end and the receiving end of the infrared detector (or the photoelectric switch).

[0045] In other embodiments, the telescopic detector 7 of the present scheme can be a detection switch or micro switch that uses the collision of mechanical moving parts to move its contacts to achieve connection or disconnection. Specifically, the contacts of the detection switch (or micro switch) can protrude and retract from the inner wall of the receiving groove 11. When the unlocking rod 2 extends out of the sleeve 3, the contacts of the detection switch (or micro switch) protrude from the inner wall of the receiving groove 11. When the unlocking rod 2 is retracted in the sleeve 3, the contacts of the detection switch (or micro switch) are retracted to the inner wall of the receiving groove 11. Therefore, the telescopic condition of the unlocking rod 2 can be known by the protrusion of the contacts of the detection switch (or micro switch).

[0046] Furthermore, the telescopic in-position detector 7 of the present solution can be electrically connected to the telescopic drive assembly 9, and the start and stop control of the telescopic drive assembly 9 can be achieved through the in-position detection of the telescopic in-position detector 7, which is beneficial to improving the degree of automation of the unlocking mechanism.

[0047] To further explain, at least two telescopic in-position detectors 7 are provided, and the two telescopic in-position detectors 7 are respectively located at two ends of the accommodating groove 11 .

[0048] In a more preferred embodiment of the present technical solution, at least two telescopic position detectors 7 are provided, one telescopic position detector 7 is used to detect whether the unlocking rod 2 is fully extended, and the other telescopic position detector 7 is used to detect whether the unlocking rod 2 is fully retracted, which is more conducive to improving the operator's grasp of the telescopic status of the unlocking rod 2.

[0049] Further explanation, it also includes a rotation in place detector 8, which is arranged close to the sleeve 3, and the detection end of the rotation in place detector 8 faces the sleeve 3, and the rotation in place detector 8 is used to detect the rotation status of the sleeve 3.

[0050] In another preferred embodiment of the present technical solution, a rotation detector 8 for detecting the rotation of the sleeve 3 is also provided, so as to indirectly obtain the state that the unlocking rod 2 is rotated to the right position and unlocked, which can further satisfy the operator's unlocking experience. Specifically, when the unlocking rod 2 is inserted into the keyhole of the lock, the sleeve 3 and the lock shell are relatively still, and the sleeve 3 and the unlocking sleeve 4 are relatively still. When the identity information read by the authorization element 5 matches the identity information of the corresponding lock code chip, the sleeve 3 rotates relative to the unlocking sleeve 4. When the unlocking mechanism is rotated, the lock core can be driven to rotate through the unlocking part 22, thereby achieving unlocking. Therefore, the locked and unlocked states of the lock core can be obtained by the rotation of the sleeve 3 relative to the unlocking mechanism.

[0051] In some embodiments, the rotation position detector 8 of the present solution can be an infrared detector or a photoelectric switch. Specifically, the present solution can be provided with a transmitting end and a receiving end of the infrared detector (or photoelectric switch) on the inner walls on both sides of the unlocking sleeve 4, and the sleeve 3 and the unlocking rod 2 are provided with avoidance channels for the emitted light to pass through. When the sleeve 3 and the unlocking sleeve 4 are relatively stationary, the transmitting end and the receiving end of the infrared detector (or photoelectric switch) are not connected; when the sleeve 3 rotates relative to the unlocking sleeve 4, and the rotation of the unlocking mechanism drives the rotation of the lock cylinder and completes the unlocking, the transmitting end and the receiving end of the infrared detector (or photoelectric switch) are connected to each other, so that the unlocking status of the lock can be known through the connection state of the transmitting end and the receiving end of the infrared detector (or photoelectric switch).

[0052] Further explained, the rotation into position detector 8 is installed on the top of the fixed base 1, and the detection end of the rotation into position detector 8 extends and retracts toward the bottom of the sleeve 3; a detection groove is provided at the bottom of the sleeve 3, and the detection groove is used to accommodate the detection end of the rotation into position detector 8.

[0053] In other embodiments, the rotation detector 8 of the present solution can be a detection switch or micro switch that uses the collision of mechanical moving parts to make its contacts move to achieve connection or disconnection. Specifically, the rotation detector 8 is installed on the fixed seat 1. When the sleeve 3 and the unlocking sleeve 4 are relatively stationary, the detection end of the rotation detector 8 shrinks and abuts against the bottom of the sleeve 3; when the sleeve 3 rotates relative to the unlocking sleeve 4, and the rotation of the unlocking mechanism drives the rotation of the lock core and completes the unlocking, the detection end of the rotation detector 8 extends out and is accommodated in the detection groove (not marked in the figure), so that the unlocking status of the lock can be known through the protrusion of the detection end of the detection switch (or micro switch).

[0054] Further, the telescopic drive assembly 9 includes a telescopic drive 91 and an output shaft 92; the telescopic drive 91 is arranged close to the fixing seat 1, the output shaft 92 is arranged inside the accommodating groove 11, and one end of the output shaft 92 is connected to the output end of the telescopic drive 91, and the other end of the output shaft 92 is connected to the mounting portion 21, and the telescopic drive 91 drives the unlocking rod 2 to move axially relative to the fixing seat 1 through the output shaft 92;

[0055] A connecting groove 211 is provided at the bottom of the mounting portion 21, and the output shaft 92 is threadedly connected to the connecting groove 211, and the output shaft 92 is rotatably arranged inside the accommodating groove 11 through the telescopic driver 91. The rotation of the output shaft 92 drives the unlocking rod 2 to move axially relative to the fixing seat 1.

[0056] Furthermore, the telescopic drive assembly 9 of the present solution includes a telescopic drive 91 and an output shaft 92, and the output shaft 92 is driven to rotate by the telescopic drive 91, so that the rotation of the output shaft 92 drives the unlocking rod 2 to move axially relative to the fixed seat 1, which is conducive to achieving stable extension and retraction of the unlocking rod 2, and has a simple structure and reliable performance. In addition, through the design of the above structure, the unlocking mechanism of the present solution can use a rotary motor as the power source for the axial movement of the unlocking rod 2. Compared with a linear motor, a rotary motor has a smaller size, which makes the size of the unlocking mechanism more compact while ensuring effective torque transmission.

[0057] Further, the outer wall of the mounting portion 21 is provided with a guide groove 212 , and the inner wall of the accommodating groove 11 is protrudingly provided with a guide block 12 , and the guide block 12 is matched and installed inside the guide groove 212 , and the guide block 12 can move along the extension direction of the guide groove 212 .

[0058] Furthermore, in order to prevent the rotation of the output shaft 92 from simultaneously driving the rotation of the unlocking rod 2, causing the unlocking rod 2 to produce a rotational displacement relative to the unlocking mechanism, which is not conducive to the normal detection of the status of each detector, the present solution also particularly provides a guide groove 212 on the outer wall of the mounting portion 21, and at the same time, a guide block 12 is protrudingly provided on the inner wall of the accommodating groove 11. Through the cooperation of the guide block 12 and the guide groove 212, the rotation of the output shaft 92 only drives the axial movement of the unlocking rod 2 to ensure the normal operation of the functions of the unlocking mechanism. In addition, when the unlocking mechanism is used to rotate the unlocking rod 2 to unlock the lock, the point of action to overcome the torque mainly falls on the guide groove 212 and the guide block 12, so that the telescopic drive 91 is not affected by the torque, so as to reduce the loss of the telescopic drive 91.

[0059] To further illustrate, a limiting groove 32 is provided at the bottom of the sleeve 3, and the limiting member 6 includes a limiting driver 61 and a limiting rod 62, and the limiting rod 62 is telescopically connected to the limiting driver 61;

[0060] When the limiting member 6 is in the unauthorized state, the limiting rod 62 extends out of the limiting driver 61 and abuts against the limiting slot 32 ; when the limiting member 6 is in the authorized state, the limiting rod 62 is retracted into the limiting driver 61 .

[0061] In a preferred embodiment of the present technical solution, the limit member 6 of the present solution is provided with a limit rod 62 that can be extended and retracted, and a limit groove 32 for accommodating the limit rod 62 is opened at the bottom of the sleeve 3. The limit rod 62 is extended and accommodated in the limit groove 32 to achieve relative stillness of the sleeve 3 and the unlocking mechanism. The structure is simple, the volume is compact, and the performance is reliable.

[0062] It should be noted that the limiting member 6 of the present solution may be an electromagnet, which is not limited here.

[0063] Further, the unlocking sleeve 4 includes an outer shell 41 and a bottom shell 42, and the bottom shell 42 is detachably mounted on the bottom of the outer shell 41; the inner end surface of the outer shell 41 is provided with a first mounting groove for mounting the authorization element 5, and the shape of the first mounting groove is "U"-shaped;

[0064] The unlocking sleeve 4 further includes an electrode 43 . The outer side wall of the shell 41 is provided with a second mounting groove, and the second mounting groove is used for mounting the electrode 43 .

[0065] In another preferred embodiment of the present technical solution, the unlocking cover 4 includes a detachably mounted outer shell 41 and a bottom shell 42. When the authorization element 5 cannot realize the recognition function, the authorization element 5 can be replaced by installing and removing the unlocking cover 4 to extend the service life of the unlocking mechanism. In addition, the present solution also reserves a second installation groove (not marked in the figure) for installing the electrode 43 in the unlocking cover 4, which is conducive to the unlocking mechanism of the present solution being used in conjunction with the electric lock and unlocking, thereby improving the versatility of the unlocking mechanism.

[0066] It should be noted that the existing electric locks are generally also provided with electrodes. When the electric lock electrodes are connected to the electrodes of the unlocking key, the unlocking key can control the conduction or disconnection of the electrodes, thereby realizing the unlocking and locking of the electric lock.

[0067] An unlocking key uses the above unlocking mechanism.

[0068] The present solution also proposes an unlocking key using the above-mentioned unlocking mechanism, which can effectively avoid the occurrence of misoperation, reduce the risk of the unlocking key becoming a "master key", and overcome the shortcomings of the prior art.
