Description

Technical Field

[0001] The present invention relates to the technical field of fingerprint collection access control locks, and in particular to a fingerprint collection auxiliary access control lock. Background Art

[0002] Fingerprint access control locks are improved upon traditional mechanical locks and are more intelligent and simplified in terms of user security, identification, and management. They are now effectively applicable to clocking in and out in different scenarios. However, existing access control locks have the following problems when in use:

[0003] 1. Due to the differences in height of existing users and the installation height of fingerprint attendance machines, some users need to place the front end of their fingers parallel to the side of the collection area when collecting fingerprints. This requires users to press and lift their wrists, causing discomfort to users.

[0004] 2. The existing collection area is generally exposed to the outside world. After repeated use by users, dirt, sweat or dust will easily accumulate on the side of the collection area, affecting the subsequent fingerprint recognition operation of others;

[0005] 3. In order to reduce the impact of impurities on the side of the collection area, electric control components such as electric push rods are set up to perform reciprocating cleaning operations on the side.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention provides a detection mechanism. The finger is placed on the side of the fingerprint recognition module for fingerprint detection. The finger presses on the middle of the fingerprint recognition module, and the fingerprint recognition module as a whole squeezes the constraint block to deform, ensuring the fit between the fingerprint recognition module and the finger. The finger presses on one side of the fingerprint recognition module, and the constraint block at the pressing position disengages from the convex part of the constraint cavity, while the constraint block on the other side remains in the convex part of the constraint cavity, so that the fingerprint recognition module rotates adaptively with the finger, ensuring the effective fit between the fingerprint recognition module and the finger. This makes it adaptable to people of different heights and improves the comfort of the user's wrist.

[0021] 2. The present invention is provided with a protective mechanism. When not in use, the mounting frame pulls the isolation plate to the side of the fingerprint recognition module for protection. The cleaning roller cleans the side of the fingerprint recognition module to ensure the cleanliness of the side of the fingerprint recognition module when not in use. When in use, the slide is pulled to make the mounting frame slide inside the slide groove to the matching cavity position. At this time, the isolation plate is pushed by the mounting frame to be folded and stored. The cleaning roller cleans the fingerprint recognition module again to ensure the cleanliness of the side of the fingerprint recognition module when in use. In this way, the cleanliness of the fingerprint recognition module before and after detection is ensured, and the fingerprint recognition module can be protected to prevent dust from falling from the side.

[0022] 3. The present invention sets a cleaning mechanism, manually rotates the driving rod counterclockwise, and causes the installation roller to rotate counterclockwise synchronously. The installation roller drives the sealing strip to receive the cleaning liquid from the liquid inlet tank. The synchronous sealing strip drives the cleaning roller to rotate frictionally. The cleaning liquid contacts the side of the cleaning roller to perform a soaking, cleaning and impurity removal operation. Then the sealing strip drives the waste cleaning liquid to the drain tank for discharge. In this way, the manual cleaning operation of the cleaning roller is completed, ensuring the subsequent cleaning effect of the cleaning roller on the fingerprint recognition module and improving the service life of the cleaning roller.

[0023] 4. The present invention provides an auxiliary mechanism to press the cleaning block to push it into the slot. The cleaning liquid in the liquid storage chamber flows from the matching slot to the inside of the cleaning block to clean the finger, thereby ensuring the cleanliness of the finger and the subsequent fingerprint reading effect.

[0024] 5. The present invention provides a card slot and a card block. When not in use, the card block is inserted into the card slot to limit the mounting frame and stabilize it, ensuring that the mounting frame pulls the isolation plate so that it only needs manual operation.

[0025] 6. The present invention provides an elastic strip, which can provide elastic support for the sealing strip, so that the sealing strip can better fit the inner wall of the connecting cavity and drive the cleaning roller to rotate, thereby ensuring the restraint of the cleaning liquid and improving the immersion, cleaning and impurity removal operation of the cleaning roller.

[0026] 7. The present invention sets up auxiliary mechanism slots and auxiliary blocks and their surrounding components. The trigger rod moves and the connecting rod can be linked to push the auxiliary block to the side position of the fingerprint recognition module, so that the fingerprint recognition module completes the constraint reset, ensuring that the constraint block slides into the convex part of the constraint cavity without deviation, and ensuring the subsequent cleaning operation and effect of other components on the fingerprint recognition module.

[0027] 8. The present invention sets up a detection mechanism, a protection mechanism, a cleaning mechanism and an auxiliary mechanism to ensure the cleanliness of the recognition module itself before and after use, the adaptive coordination of finger recognition, and the cleaning operation of the finger itself, thereby ensuring the fingerprint recognition effect and adaptation used by different people. Each component only needs to be operated manually, and there is no need to set up an electronic control component. The cost of manufacturing the access control lock is reduced while meeting the required functions. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific examples, but the following examples are only preferred embodiments of the present invention, not all. Based on the examples in the embodiments, other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention. The experimental methods in the following examples, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following examples, unless otherwise specified, can be obtained from commercial channels.

[0040] Example: Figure 1 and Figure 2 As shown, a fingerprint collection-assisted access control lock includes a main body 1, which is a rectangular body with an integrated lithium battery, a control panel, and a touch screen. After fingerprint collection, the feedback is sent to the control panel for access control identification and clocking in, and the access control information is displayed on the touch screen. A detection mechanism 2 that can adaptively detect fingerprints is provided on the side of the main body 1. A protection mechanism 3 that can be manually protected is provided on the side of the detection mechanism 2. A cleaning mechanism 4 that can automatically clean is provided at the position corresponding to the protection mechanism 3 inside the main body 1. An auxiliary mechanism 5 for assisting in correcting deviation and cleaning fingers is provided on the lower side of the main body 1.

[0041] The detection mechanism 2 can be adapted to different people and can be attached to the side of the finger to perform fingerprint recognition operations;

[0042] like Figures 1 to 6As shown, the detection mechanism 2 includes an open cavity 21 opened on the side of the main body 1, and the open cavity 21 is a ladder-shaped cavity. An active cavity 22 is opened on the inner wall of the open cavity 21, and the active cavity 22 is a rectangular cavity with arcs on both sides. A constraint cavity 23 is symmetrically opened on the inner walls of both sides of the active cavity 22, and the constraint cavity 23 is a concave cavity. A fingerprint recognition module 24 is movably installed inside the active cavity 22, and the detection surface of the fingerprint recognition module 24 is flush with the inner wall of the open cavity 21. The fingerprint recognition module 24 is a rectangular block with an internal integrated fingerprint detection sensor and a circuit board, and the chamfers on both sides are arc-shaped. This technical solution does not limit the fingerprint recognition module 24, and all existing modules that can detect fingerprints can be used. Constraint blocks 25 are equidistantly fixedly installed on both sides of the fingerprint recognition module 24, and the constraint blocks 25 are movably installed at the raised position inside the constraint cavity 23. The constraint blocks 25 are cylindrical blocks, and are fixed on the sides of the fingerprint recognition module 24 and the active cavity A first support block 26 is symmetrically fixedly connected between the inner walls of the dynamic cavity 22. The first support block 26 is a "W"-shaped block made of spring steel. Specifically, when the finger contacts the middle position of the fingerprint recognition module 24, the fingerprint recognition module 24 as a whole presses the first support block 26 to deform it and elastically support it, so that the fingerprint recognition module 24 effectively fits the side of the finger. When the finger contacts the side position of the fingerprint recognition module 24, the constraint block 25 at the corresponding position slides out of the bulge of the constraint cavity 23, squeezing and deforming the constraint block 25. At this time, the fingerprint recognition module 24 rotates with the support of another constraint block 25 set at the bulge of the constraint cavity 23, so that the fingerprint recognition module 24 can better adapt to the finger and fit it. After the finger leaves the side of the fingerprint recognition module 24, all the constraint blocks 25 slide into the bulge of the constraint cavity 23 under the elastic support of the constraint block 25, completing the reset operation of the fingerprint recognition module 24.

[0043] The protection mechanism 3 is provided to perform daily protection operations on the detection mechanism 2, and manual cleaning operations can be performed when in use;

[0044] like Figures 3 to 5 、 Figure 7 and Figure 8As shown, the protective mechanism 3 includes a slide groove 31 symmetrically opened on the inner wall of the cavity 21 on both sides, and the slide groove 31 extends through the main body 1. The slide groove 31 is a rectangular groove, and a matching cavity 32 is opened on the bottom wall of the cavity 21. The matching cavity 32 coincides with the slide groove 31. The matching cavity 32 is a convex cavity. A slide plate 33 is movably installed inside the slide groove 31 and the slide plate 33 extends out of the slide groove 31 to the side position of the main body 1. The slide plate 33 is a "C"-shaped plate. A mounting bracket 34 is fixedly installed on the side of the slide plate 33, and the mounting bracket 34 is movably installed in the slide groove 31, the mounting frame 34 corresponds to the upper side of the fingerprint recognition module 24, the mounting frame 34 is a U-shaped frame, a cleaning roller 35 is provided inside the mounting frame 34, and the cleaning roller 35 is rotated on the side of the mounting frame 34 through a round rod, the mounting frame 34 is a cylindrical roller made of absorbent cotton, an isolation plate 36 is fixedly connected between the side of the mounting frame 34 and the inner wall of the matching cavity 32, and the isolation plate 36 is movably installed in the inner position of the slide 31, the isolation plate 36 is a rectangular plate with a continuous "W" shape in cross section, and is installed in the mounting frame 34 away from the slide 33. A card slot 37 is symmetrically opened on the side. The card slot 37 is a circular slot with a convex cross-section. A card block 38 is clamped inside the card slot 37 and the card block 38 is fixedly installed on the inner wall of the slide 31. The card block 38 is a cylindrical spring buckle. Specifically, in the default non-use state, the slide plate 33 is pushed to make the mounting bracket 34 slide inside the slide 31 to the position above the fingerprint recognition module 24. The card block 38 is inserted into the card slot 37 to limit and stabilize the mounting bracket 34, and the mounting bracket 34 pulls the isolation plate 36 to stretch. The side of the fingerprint recognition module 24 is protected. At this time, the cleaning roller 35 cleans the side of the fingerprint recognition module 24 once, ensuring the cleanliness of the side of the fingerprint recognition module 24 when not in use. When in use, the slide plate 33 is pulled to disengage the block 38 from the inside of the card slot 37, and the mounting frame 34 slides inside the slide slot 31 to the position of the matching cavity 32. At this time, the isolation plate 36 is pushed by the mounting frame 34 to fold and store. The cleaning roller 35 cleans the fingerprint recognition module 24 again, ensuring the cleanliness of the side of the fingerprint recognition module 24 when in use.

[0045] The cleaning mechanism 4 can be used to clean the protection mechanism 3, ensuring the normal use of the protection mechanism 3, and can cooperate with subsequent components to supply liquid to clean the fingers;

[0046] like Figures 1 to 5 and Figure 9As shown, the cleaning mechanism 4 includes a liquid storage chamber 41 provided inside the main body 1, the inner cavity of the liquid storage chamber 41 retains a columnar shape of the main body 1, the liquid storage chamber 41 is a U-shaped chamber, a liquid injection hole 42 is provided on the side of the main body 1 that passes through the main body 1 to the inside of the liquid storage chamber 41, the liquid injection hole 42 is a circular hole, an inspection block 43 that passes through the main body 1 is provided on the inner wall of the liquid storage chamber 41, the inspection block 43 is a rectangular block of transparent material, a connecting chamber 44 is provided inside the main body 1, and the connecting chamber 44 intersects with the matching chamber 32, the connecting chamber 44 is a cylindrical chamber, a mounting roller 441 is movably installed inside the connecting chamber 44, the mounting roller 441 is a circular roller, and a driving roller is fixedly installed on the side of the mounting roller 441 The driving rod 442 extends through the main body 1, and the driving rod 442 is a "T"-shaped rod. A sealing strip 443 is fixedly installed in an array at equal intervals on the side circumference of the mounting roller 441, and the sealing strip 443 is fitted on the inner wall of the connecting cavity 44. The sealing strip 443 is a "U"-shaped strip made of elastic rubber. Elastic strips 444 are fixedly installed in an array at equal intervals on the side circumference of the mounting roller 441, and the sealing strip 443 is fitted on the inner side of the sealing strip 443. The elastic strip 444 is a "T"-shaped strip made of elastic material. A liquid inlet groove 45 is provided on the inner wall of the liquid storage cavity 41, which passes through the main body 1 to the inside of the connecting cavity 44. A liquid inlet groove 45 is provided on the lower side of the main body 1, which passes through the main body The drain groove 46 of the main body 1 to the connecting cavity 44, the liquid inlet groove 45 and the drain groove 46 are rectangular grooves, and a connecting frame 47 is fixedly installed on the lower side of the main body 1. The connecting frame 47 is an "L"-shaped frame with a rectangular groove on the side. A collecting box 48 is movably installed inside the connecting frame 47, and the collecting box 48 is a rectangular box with a hollowed-out side. Specifically, when the cleaning roller 35 slides into the matching cavity 32, the injection hole 42 is manually rotated counterclockwise to drive the installation roller 441 to rotate synchronously. At this time, the sealing strip 443 is attached to the inner wall of the connecting cavity 44 to make its adjacent position a closed space. The cleaning liquid is added to the liquid storage cavity 41 through the injection hole 42, and the cleaning liquid flows from the liquid inlet groove 45 into the closed space. When the mounting roller 441 rotates between the sealing strips 443, the sealing strips 443 synchronously contact the cleaning roller 35 for frictional rotation. At the same time, the cleaning liquid between the sealing strips 443 contacts the side of the cleaning roller 35 to achieve a cleaning effect. Subsequently, the cleaned cleaning liquid is constrained by the sealing strips 443 to be discharged to the position of the drain groove 46, and the discharged cleaning liquid falls into the collection box 48 for collection. In this way, the cleaning operation of the cleaning roller 35 is completed, so that it can subsequently have a better cleaning effect on the fingerprint recognition module 24; the elastic strip 444 provided therein can play an elastic supporting effect on the sealing strip 443, so that the sealing strip 443 can better fit the inner wall of the connecting cavity 44 and drive the cleaning roller 35 to rotate.

[0047] The auxiliary mechanism 5 can cooperate with the cleaning mechanism 4 to clean the finger and trigger the detection mechanism 2 to perform a correction operation to ensure the subsequent cleaning effect of the fingerprint recognition module 24;

[0048] like Figure 3 ,like Figure 4 and Figure 10 As shown, the auxiliary mechanism 5 includes a connecting groove 51 provided on the inner wall of the movable cavity 22, the connecting groove 51 is a rectangular groove, an auxiliary block 511 is movably installed inside the connecting groove 51, the auxiliary block 511 is a "C"-shaped block, and a return spring 512 is fixedly connected equidistantly between the side of the auxiliary block 511 and the inner wall of the connecting groove 51, a slot 52 is provided on the inner wall of the connecting groove 51 that passes through the main body 1 and the slot 52 is arranged in the inner position of the columnar main body 1 retained in the inner cavity of the liquid storage cavity 41, the slot 52 is an "L"-shaped slot, a connecting rod 521 is movably installed inside the slot 52 and the connecting rod 521 is fixedly connected to the auxiliary block 5 11 side position, the connecting rod 521 is a ladder-shaped rod, and a trigger rod 522 is movably installed in the position of the connecting rod 521 inside the slot 52, and the trigger rod 522 extends to the lower side of the main body 1. The trigger rod 522 is a ladder-shaped rod. A cleaning block 523 is fixedly installed on the lower side of the trigger rod 522. The cleaning block 523 is a rectangular block made of absorbent cotton. A constraint groove 53 is symmetrically opened on the inner wall of the slot 52. The constraint groove 53 is a rectangular groove. A connecting block 531 is movably installed inside the constraint groove 53 and the connecting block 531 is fixedly installed on the side position of the trigger rod 522. The connecting block 531 is made of elastic rubber. A second supporting block 532 is fixedly connected between the side of the connecting block 531 and the inner wall of the constraint groove 53. The second supporting block 532 is a rectangular block made of spring steel with a continuous "W"-shaped cross-section. A matching groove 54 is equidistantly provided on the inner wall of the constraint groove 53 corresponding to the connecting block 531, which passes through the main body 1 to the inside of the liquid storage chamber 41. The matching groove 54 is a rectangular groove. Specifically, before use, press the finger on the side of the cleaning block 523 to push the trigger rod 522 to slide upward and squeeze the connecting rod 521. The synchronous connecting rod 521 pushes the auxiliary block 511 to constrain the fingerprint recognition module 24 to complete the reset operation. At this time, the cleaning block 523 slides into the position corresponding to the constraint groove 53 inside the slot 52, and the provided connecting block 531 slides inside the constraint groove 53 to constrain the trigger rod 522. The cleaning liquid inside the liquid storage chamber 41 flows from the matching groove 54 to the side of the cleaning block 523 and is attracted to clean the finger. After the finger is removed, the elastic force of the reset spring 512 and the second support block 532 completes the reset of the auxiliary block 511, the connecting rod 521, the trigger rod 522 and the connecting block 531, and the connecting block 531 blocks the matching groove 54. The cleaning liquid remaining inside the cleaning block 523 will fall into the collection box 48 for collection.

[0049] Working principle:

[0050] Before use: First, press the cleaning block 523 with your finger to push it into the slot 52. The cleaning liquid in the liquid storage chamber 41 flows from the matching slot 54 into the cleaning block 523 to clean your finger. The synchronous trigger rod 522 moves to link the connecting rod 521 to push the auxiliary block 511 to the side of the fingerprint recognition module 24, so that the fingerprint recognition module 24 completes the constraint reset and ensures that the constraint block 25 slides into the convex part of the constraint chamber 23 without deviation, ensuring the subsequent cleaning operation and effectiveness of other components on the fingerprint recognition module 24. Then, move your finger away from the side of the cleaning block 523, and all components are reset to ensure the cleanliness of the finger and the subsequent fingerprint reading effect.

[0051] In the second step, manually pull the slide plate 33 to make the mounting frame 34 slide inside the slide groove 31, and the block 38 is released from the inside of the card slot 37. The mounting frame 34 drives the cleaning roller 35 to rotate and rub against the side of the fingerprint recognition module 24 to perform a pre-use cleaning operation. The mounting frame 34 squeezes the isolation plate 36 to fold and the mounting frame 34 is stored in the matching cavity 32 at the same time. This ensures the cleanliness of the fingerprint recognition module 24 before detection and ensures the best detection effect.

[0052] During use: First, place your finger on the side of the fingerprint recognition module 24 for fingerprint detection. The finger presses on the middle of the fingerprint recognition module 24. The fingerprint recognition module 24 as a whole squeezes the constraint block 25 to deform, ensuring the fit between the fingerprint recognition module 24 and the finger. The finger presses on one side of the fingerprint recognition module 24. The constraint block 25 at the pressing position disengages from the bulge of the constraint cavity 23. The constraint block 25 on the other side remains in the bulge of the constraint cavity 23, allowing the fingerprint recognition module 24 to rotate adaptively with the finger, ensuring the effective fit between the fingerprint recognition module 24 and the finger, and improving the comfort of the user's wrist.

[0053] In the second step, if the fingerprint recognition is still unqualified or invalid, the cleaning block 523 is pressed again with the finger to clean and reset the fingerprint recognition module 24. The sliding plate 33 is pushed to make the cleaning roller 35 slide back and forth on the side of the fingerprint recognition module 24 to clean the fingerprint recognition module 24 again before the fingerprint recognition operation is carried out.

[0054] After use: First, manually rotate the driving rod 442 counterclockwise to make the installation roller 441 rotate counterclockwise synchronously. The installation roller 441 drives the sealing strip 443 to take the cleaning liquid from the liquid inlet tank 45. The sealing strip 443 drives the cleaning roller 35 to rotate by friction. The cleaning liquid contacts the side of the cleaning roller 35 to soak and clean the impurities. Then the sealing strip 443 drives the waste cleaning liquid to the drain tank 46 for discharge. In this way, the manual cleaning operation of the cleaning roller 35 is completed, ensuring the subsequent cleaning effect of the cleaning roller 35 on the fingerprint recognition module 24 and improving the service life of the cleaning roller 35.

[0055] In the second step, the slide plate 33 is pushed to slide the mounting frame 34 to a position above the fingerprint recognition module 24. The clamping block 38 is engaged with the inside of the clamping slot 37 to limit and fix the mounting frame 34. The cleaning roller 35 simultaneously cleans the side of the fingerprint recognition module 24 again to ensure the cleanliness of the fingerprint recognition module 24 when not in use. The isolation plate 36 is pulled by the mounting frame 34 to protect and isolate the side of the fingerprint recognition module 24 to prevent dust from falling to the side of the fingerprint recognition module 24.

[0056] In the third step, the remaining amount of cleaning liquid in the liquid storage chamber 41 is detected by the inspection block 43, and cleaning liquid is added from the liquid injection hole 42. Then, the collection box 48 is removed from the side of the connecting frame 47 to pour out the collected waste cleaning liquid and reset it.

[0057] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
