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 from traditional mechanical locks and are more intelligent and simple in terms of user security, identification, and management. They are now effectively applicable to clocking in in different scenarios. However, when using existing access control locks, the following problems still exist through observation: 1. Due to the difference in height of existing users and the difference in 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, which requires users to press and lift their wrists, causing discomfort to users; 2. The existing collection area is generally exposed to the outside space. After repeated use by users, dirt, sweat or dust is easily left on the side of the collection area, affecting the subsequent fingerprint recognition operation of other people; 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. However, this will increase the cost of the access control lock and is not convenient for mass production. For this reason, we propose a fingerprint collection auxiliary access control lock.

[0012] 2. The present invention provides a protective mechanism. When not in use, the mounting frame pulls the isolation plate to stretch it 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.

[0014] 4.

[0015] 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 position of the mounting frame and stabilize it, thereby ensuring that the mounting frame pulls the isolation plate, so that it only needs manual operation.

[0016] 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 control of the cleaning liquid and improving the immersion, cleaning and impurity removal operation of the cleaning roller.

The trigger rod moves and can link the connecting rod 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 will not deviate when sliding into the protrusion of the constraint cavity, and ensuring the subsequent cleaning operation and effect of other components on the fingerprint recognition module.

[0018] 8.

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 is separated from 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; The protection mechanism 3 can be used to perform daily protection operations on the detection mechanism 2, and manual cleaning operations can be performed when in use; like Figures 3 to 5 , Figure 7 and Figure 8As shown, the protection mechanism 3 includes a slide groove 31 symmetrically opened on the inner wall of both sides of the opening cavity 21, and the slide groove 31 extends through the main body 1, the slide groove 31 is a rectangular groove, a matching cavity 32 is opened on the bottom wall of the opening cavity 21, and the matching cavity 32 coincides with the slide groove 31, and 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 from the slide groove 31 to the side position of the main body 1, the slide plate 33 is a "C"-shaped plate, and a mounting frame 34 is fixedly installed on the side of the slide plate 33, and the mounting frame 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 arranged inside the mounting frame 34, and the cleaning roller 35 is rotated at 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 groove 31, the isolation plate 36 is a rectangular plate with a continuous "W"-shaped cross section, and the mounting frame 34 is away from the slide plate 33. A card slot 37 is symmetrically provided on the side surface. 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 slot 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 frame 34 slide inside the slide slot 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 frame 34, and the mounting frame 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 card block 38 from 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 be folded and stored, and 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; 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; like Figures 1 to 5 and Fig. 9As shown, the cleaning mechanism 4 includes a liquid storage chamber 41 opened 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 opened on the side of the main body 1 and 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 is set on the inner wall of the liquid storage chamber 41 and passes through the main body 1, the inspection block 43 is a rectangular block of transparent material, a connecting chamber 44 is opened 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 provided on the lower side of the main body 1. The body 1 is connected to the drainage groove 46 inside the connecting cavity 44, the inlet groove 45 and the drainage 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, and a collecting box 48 is movably installed inside the connecting frame 47. The collecting box 48 is a rectangular box with one side hollowed out; 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 so that its adjacent position is a closed space, and the cleaning liquid is added to the liquid storage cavity 41 through the injection hole 42, and the cleaning liquid flows from the inlet groove 45 into the closed space. When the installation roller 441 rotates between the sealing strips 443, the sealing strips 443 synchronously contact the cleaning roller 35 for frictional rotation, and 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, and then the 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, so that 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; The auxiliary mechanism 5 can cooperate with the cleaning mechanism 4 to clean the finger, and can trigger the detection mechanism 2 to perform a correction operation to ensure the subsequent cleaning effect of the fingerprint recognition module 24; like Figure 3 ,like Figure 4 and Fig.10 As shown, the auxiliary mechanism 5 includes a connecting groove 51 provided on the inner wall of the active 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, a reset spring 512 is equidistantly fixedly connected between the side of the auxiliary block 511 and the inner wall of the connecting groove 51, a slot 52 penetrating the main body 1 is provided on the inner wall of the connecting groove 51, 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, a trigger rod 522 is movably installed at the position of the connecting rod 521 in the inner part of 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 at the lower side of the trigger rod 522, and the cleaning block 523 is a rectangular block made of absorbent cotton, and a constraint groove 53 is symmetrically opened on the inner wall of the slot 52, and 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 at the side position of the trigger rod 522, and the connecting block 531 is made of elastic rubber.

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 of the constraint groove 53 corresponding to the inside of the slot 52, and the set connecting block 531 slides inside the constraint groove 53 to constrain the trigger rod 522. The cleaning liquid in the liquid storage chamber 41 flows from the matching groove 54 to the side of the cleaning block 523 for suction to clean the finger. After the finger is removed, the auxiliary block 511, the connecting rod 521, the trigger rod 522 and the connecting block 531 are reset under the elastic force of the reset spring 512 and the second support block 532. The connecting block 531 blocks the matching groove 54, and the cleaning liquid remaining in the cleaning block 523 will fall into the collection box 48 for collection.

[0023] Working principle: 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 to the cleaning block 523 to clean the 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, ensuring that the constraint block 25 slides into the convex part of the constraint chamber 23 without deviation, ensuring the subsequent cleaning operation and effect of other components on the fingerprint recognition module 24, and then the finger moves away from the side of the cleaning block 523, and each component completes the reset, ensuring the cleanliness of the finger and the subsequent fingerprint reading effect; In the second step, the slide plate 33 is manually pulled to make the mounting frame 34 slide inside the slide slot 31, and the block 38 is separated from the inside of the 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 cleaning operation before use. The mounting frame 34 squeezes the isolation plate 36 to fold and the mounting frame 34 is synchronously stored in the internal position of the matching cavity 32, so as to ensure the cleanliness of the fingerprint recognition module 24 before detection and ensure the best detection effect; When in use: First, place the finger on the side of the fingerprint recognition module 24 for fingerprint detection, wherein the finger is pressed on the middle of the fingerprint recognition module 24, and the fingerprint recognition module 24 as a whole squeezes the constraint block 25 to deform, thereby ensuring the fit between the fingerprint recognition module 24 and the finger, and the finger is pressed on one side of the fingerprint recognition module 24, and the constraint block 25 at the pressed position is separated from the convex part of the constraint cavity 23, and the constraint block 25 on the other side is kept at the convex part of the constraint cavity 23, so that the fingerprint recognition module 24 rotates adaptively with the finger, thereby ensuring the effective fit between the fingerprint recognition module 24 and the finger, and improving the comfort of the user's wrist; In the second step, if the fingerprint recognition is still unqualified or invalid, the cleaning block 523 is pressed again by the finger to clean and correct the fingerprint recognition module 24, and 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, and the fingerprint recognition module 24 is cleaned again, and then the fingerprint detection operation is used; 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 perform a soaking and cleaning and impurity removal operation. 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. In the second step, the slide plate 33 is pushed to make the mounting frame 34 slide to the position above the fingerprint recognition module 24, and the mounting frame 34 is limited and fixed by the clamping block 38 being clamped in the clamping slot 37. The cleaning roller 35 simultaneously performs another cleaning operation on the side of the fingerprint recognition module 24 to ensure the cleanliness of the fingerprint recognition module 24 when it is 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. The third step is to detect the remaining amount of cleaning liquid in the liquid storage chamber 41 through the inspection block 43, add cleaning liquid from the injection hole 42, and then remove the collection box 48 from the side of the connecting frame 47 to pour out the collected waste cleaning liquid and reset it.

[0024] 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, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
