Fingerprint lock with protection processing structure

Abstract

The application relates to a fingerprint lock with a protection treatment structure applied to the field of intelligent locks. Through cooperation of a self-change protection layer and a micro heating unit, a variable protection layer can be generated on the surface of an electronic password disc. After each time of opening the door, the micro heating unit is heated, so that the self-change protection layer and the fingerprint-eliminating nail are expanded. When the outer cover is lowered and reset, the fingerprint-eliminating nail is lowered and rubs against the surface of the self-change protection layer, so that the marks on the surface of the self-change protection layer are consistent, and individual marks are not prone to appearing. Compared with the prior art, the marks generated after each time of inputting a password or a fingerprint can be automatically eliminated, the risk of password or fingerprint leakage is greatly reduced, and the security risk is effectively reduced.

Description

Technical Field

[0001] The present invention relates to a fingerprint lock, and more particularly to a fingerprint lock with a protective treatment structure for use in the field of smart locks. Background Technology

[0002] Fingerprint locks are smart locks, a perfect fusion of computer information technology, electronic technology, mechanical technology, and modern hardware craftsmanship. Fingerprint authentication is convenient, fast, and accurate. With the popularization of technology and the development of smart homes, more and more people are choosing fingerprint locks.

[0003] Fingerprint locks are a product of intelligent technology, which can be unlocked by electronic passwords, fingerprints, magnetic cards, and mechanical keys. However, smart locks have a security risk: when entering electronic passwords or fingerprints, marks or fingerprints are easily left, which can lead to leaks and compromise the security. Summary of the Invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is the security risk of smart locks having easily leaked passwords or fingerprints.

[0005] To address the aforementioned problems, this invention provides a fingerprint lock with a protective structure, comprising a lock body with a control chip. From top to bottom, the lock body includes an electronic keypad, a fingerprint reader, a magnetic card sensing area, and a keyhole. A handle is rotatably connected to the surface of the lock body. The fingerprint reader, magnetic card sensing area, keyhole, and bolt on the lock body are all signal-connected to the control chip. The handle is located between the keyhole and the magnetic card sensing area. Two slide rails are mounted on the front end of the lock body, located at the left and right ends of the electronic keypad. An outer protective cover is slidably connected to the two slide rails, covering the outside of the electronic keypad and the fingerprint reader. A self-changing protective layer is fixedly connected to the surface of both the electronic keypad and the fingerprint reader. The self-changing protective layer has a double-sealed structure and is filled with a two-state liquid. A micro-heating unit is installed inside the outer protective cover. The slide rails and the micro-heating unit are signal-connected to the control chip.

[0006] In fingerprint locks with protective structures, the automatic removal of fingerprints or marks can be achieved through the combination of a self-adjusting protective layer and a micro-heating unit. Compared with existing technologies, this significantly reduces the risk of password or fingerprint leakage and effectively reduces security risks.

[0007] As a further improvement of this application, the self-changing protective layer includes a substrate attached to the surface of the electronic password disk or fingerprint reader, a limiting layer fixedly connected to the upper and lower ends of the substrate, and a textured layer fixedly connected to one end of the two limiting layers that are close to each other. The dual-state liquid is filled in the cavity formed by the textured layer, the limiting layer and the substrate.

[0008] As a further improvement of this application, the textured layer is an elastic transparent structure, the limiting layer is a non-elastic transparent structure, and the film is a rigid transparent fixed structure, and both the textured layer and the limiting layer are in a taut state.

[0009] As a further improvement of this application, the electronic keypad includes a key area for displaying numbers and a blank area located outside the key area, the key area being completely covered by a textured layer.

[0010] As a further improvement of this application, multiple anti-marking pins are fixedly connected to the inner wall of the outer protective cover. The multiple anti-marking pins are all located below the button area, and the multiple anti-marking pins correspond to multiple columns of numbers in the button area. The micro heating unit is installed inside the anti-marking pins.

[0011] As a further improvement of this application, the anti-marking nail includes a rod body, an anti-marking sleeve fixedly connected to the end of the rod body, and a plurality of heat-conducting strips fixedly connected to the end of the rod body near the anti-marking sleeve. The plurality of heat-conducting strips are embedded in the anti-marking sleeve. The anti-marking sleeve includes a heat-concentrating plate and a near-marking sac fixedly connected to the outer end of the heat-concentrating plate. The heat-conducting strips are fixedly connected through the heat-concentrating plate and in contact with each other.

[0012] As a further improvement of this application, the micro heating unit is a heating element, and the heating element is disposed in the rod body. The heat-conducting strip is a rigid heat-conducting structure. The near-stretch sac is saturated with helium gas, and when the heating unit is not working, the near-stretch sac does not come into contact with the self-variant protective layer.

[0013] As another improvement of this application, a plurality of uniformly distributed anti-wrinkle plates are fixedly connected to the end of the scrotum near the self-protective layer, and the plurality of anti-wrinkle plates are all connected to the scrotum.

[0014] As a further improvement to this application, the end face of the near-seal bladder that does not contact the heat-collecting plate and the anti-seal plate are both elastic sealing structures, and an anti-seal ring is fixedly connected to the outward-facing surface of the anti-seal plate. The anti-seal ring has a spiral structure.

[0015] In summary, by combining the self-changing protective layer and the micro-heating unit, a variable protective layer can be generated on the surface of the electronic keypad. After each opening, the micro-heating unit heats the layer, causing the self-changing protective layer and the fingerprint-removing pins to expand. When the outer cover moves down to its reset position, the fingerprint-removing pins also move down and rub against the surface of the self-changing protective layer, making the imprint on the surface of the self-changing protective layer more uniform and less likely to appear as individual imprints. Compared with existing technologies, this technology can automatically eliminate the imprints generated after each password or fingerprint input, thereby significantly reducing the risk of password or fingerprint leakage and effectively reducing security risks.

[0028] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0029] First implementation method:

[0030] Figure 1-2A fingerprint lock with a protective structure is shown, including a lock body 1 with a control chip. The lock body 1 has an electronic keypad 104, a fingerprint reader 103, a magnetic card sensing area 102, and a keyhole 101 arranged sequentially from top to bottom. A handle 2 is also rotatably connected to the surface of the lock body 1. The fingerprint reader 103, the magnetic card sensing area 102, the keyhole 101, and the bolt on the lock body 1 are all signal-connected to the control chip. The handle 2 is located between the keyhole 101 and the magnetic card sensing area 102. Two slide rails 31 are installed at the front end of the lock body 1, located at the left and right ends of the electronic keypad 104, respectively. An outer protective cover 32 is slidably connected to the two slide rails 31, covering the outside of the electronic keypad 104 and the fingerprint reader 103.

[0031] like Figure 3-4 Both the electronic keypad 104 and the fingerprint reader 103 have a self-changing protective layer 4 fixedly connected to their surfaces. The self-changing protective layer 4 has a double-layer sealed structure, and its interior is filled with a two-state liquid, the main component of which is alcohol. A micro-heating unit is installed inside the outer cover 32. The slide rail 31 and the micro-heating unit are both connected to the control chip. The self-changing protective layer 4 includes a base plate on the surface of the electronic keypad 104 or the fingerprint reader 103, a limiting layer 42 fixedly connected to the upper and lower ends of the base plate, and a textured layer 41 fixedly connected to one end of the two limiting layers 42 that are close to each other. The two-state liquid fills the cavity formed by the textured layer 41, the limiting layer 42, and the base plate. Figure 5-6 Each time the fingerprint is unlocked via the fingerprint reader 103 or the electronic keypad 104, the pressing of the finger causes the self-adjusting protective layer 4 to deform and then recover its shape. Simultaneously, with the operation of micro-heating, the ambient temperature of the self-adjusting protective layer 4 gradually increases due to the easy vaporization of alcohol, causing it to vaporize and expand. This causes the imprint on the surface of the self-adjusting protective layer 4 to undergo a certain degree of blurring and misalignment, thereby effectively reducing the risk of fingerprint leakage. In addition, the fingerprint on the fingerprint reader 103 undergoes a certain degree of micro-deformation and blurring, further reducing the risk of fingerprint leakage.

[0032] The textured layer 41 is an elastic transparent structure, the limiting layer 42 is a non-elastic transparent structure, and the substrate is a rigid transparent fixed structure. Both the textured layer 41 and the limiting layer 42 are in a taut state, so that they do not easily affect the user's operation of the fingerprint reader 103 and the electronic keypad 104.

[0033] The electronic keypad 104 includes a keypad area for displaying numbers and a blank area located outside the keypad area, and the keypad area is completely covered by a textured layer 41.

[0034] like Figure 7-8Multiple texture-removing pins 5 are fixedly connected to the inner wall of the outer protective cover 32. These pins 5 are all located below the button area, and each pin corresponds to a different column of numbers in the button area. A micro-heating unit is installed within each texture-removing pin 5. Each texture-removing pin 5 includes a rod 51, a texture-removing sleeve fixedly connected to the end of the rod 51, and multiple heat-conducting strips 53 fixedly connected to the end of the rod 51 near the texture-removing sleeve. The heat-conducting strips 53 are embedded within the texture-removing sleeve. The texture-removing sleeve includes a heat-collecting plate 521 and a near-texture sac 522 fixedly connected to the outer end of the heat-collecting plate 521. The heat-conducting strips 53 are fixedly inserted through the heat-collecting plate 521 and... In this embodiment, four fingerprint-removing pins 5 are in contact with the fingerprint sac 522. Three of the fingerprint-removing pins 5 correspond to the numbers in the bottom row of the case area, and the last fingerprint-removing pin 5 corresponds to the fingerprint reader 103. After the outer cover 32 is slid open, the control chip controls the micro heating unit to heat the fingerprint sac 522, causing it to expand. After unlocking, when the outer cover 32 is manually slid back to its original position, the expanded fingerprint sac 522 can directly rub against the electronic keypad 104, thereby achieving the effect of automatically removing fingerprints or password marks after each unlocking.

[0035] The slide rail 31 can also be an electric slide rail, so that the outer cover 32 can be automatically reset after each unlocking.

[0036] The micro heating unit is a heating element, and the heating element is set inside the rod 51. The heat-conducting strip 53 is a rigid heat-conducting structure. The near-stretch sac 522 is saturated with helium gas. In the gas, its thermal conductivity is high. When heated, it is easy to expand, which facilitates the expansion of the near-stretch sac 522 to approach the electronic password disk 104. When the heating unit is not working, the near-stretch sac 522 does not come into contact with the self-variant protective layer 4.

[0037] It is worth noting that the fingerprint reader 103 is set up separately from the electronic keypad 104 in the illustration. This setting method is common in the prior art. In specific implementation, it can also be integrated with the electronic keypad 104, that is, under-display fingerprint recognition, which can reduce the difficulty of removing fingerprint or password marks and make it more convenient to use.

[0038] In summary, by combining the self-changing protective layer 4 and the micro-heating unit, a variable protective layer can be generated on the surface of the electronic keypad 104. After each opening, the micro-heating unit heats the layer, causing the self-changing protective layer 4 and the fingerprint-removing pins 5 to expand. When the outer cover 32 moves down to its reset position, the fingerprint-removing pins 5 move down as well, rubbing against the surface of the self-changing protective layer 4. This makes the markings on the surface of the self-changing protective layer 4 more consistent, reducing the likelihood of individual markings. Compared to existing technologies, this method can automatically eliminate markings after each password or fingerprint input, significantly reducing the risk of password or fingerprint leakage and effectively mitigating security risks.

[0039] Second implementation method:

[0040] Based on the first embodiment, this embodiment adds a fingerprint-removing piece 54 and sets 11 fingerprint-removing pins 5, which correspond to the 10 Arabic numerals in the button area and the fingerprint reader 103 respectively. The rest is consistent with the first embodiment.

[0041] Figure 8 As shown, a plurality of uniformly distributed anti-slip plates 54 are fixedly connected to the end of the near-slip sac 522 near the self-variant protective layer 4. The plurality of anti-slip plates 54 are all connected to the near-slip sac 522. The end face of the near-slip sac 522 that does not contact the heat-collecting plate 521 and the anti-slip plates 54 are both elastic sealing structures. An anti-slip ring 501 is fixedly connected to the outward-facing surface of the anti-slip plate 54. The anti-slip ring 501 has a spiral structure.

[0042] After the smart lock is opened by electronic password or fingerprint, and the outer cover 32 is reset, the control chip controls the micro heating unit inside the corresponding fingerprint removal nail 5 to turn on and heat it, causing the fingerprint removal nail 5 to expand. At the same time, due to the increase in temperature, the binary liquid partially vaporizes, and the self-protecting layer 4 also gradually bulges outward, so that the fingerprint removal nail 5 and the self-protecting layer 4 gradually come into contact with each other. Meanwhile, as the fingerprint removal plate 54 expands with the fingerprint removal nail 5, the fingerprint removal ring 501 on its surface gradually expands outward, thereby blurring the imprint or fingerprint on the surface of the self-protecting layer 4, achieving the effect of eliminating fingerprints. At the same time, it makes the imprint on the surface of the button area more uniform. Compared with the first embodiment, in this embodiment, the fingerprint removal nail 5 directly contacts the self-protecting layer 4 without the need for a large amount of friction with the surface of the self-protecting layer 4, which can effectively protect the self-protecting layer 4 from damage due to friction, thereby effectively maintaining the protection of the fingerprint reader 103 and the electronic keypad 104 surface by the self-protecting layer 4.

[0043] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
