Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to a privacy-protecting smart fingerprint lock. Background Technology

[0002] A smart fingerprint lock is a new type of lock that integrates modern electronic and mechanical technologies. It primarily unlocks the lock by recognizing the user's fingerprint, but it can also be opened by entering a password via a touchscreen.

[0003] Chinese patent application CN202420228763.0 discloses an intelligent fingerprint lock. The key technical points of the solution are: when the protective baffle is closed, it simultaneously protects the fingerprint module and the digital input panel, preventing them from being directly exposed to the outside and accumulating dust when not in use. By lifting the extension block, the extension block can move the protective baffle upwards and open together, allowing users to unlock with fingerprints or digital passwords. When the protective baffle moves to its position, the magnetic block will attract and fix the magnetic rubber sheet, keeping the protective baffle stationary. At the same time, the limiting groove will limit and guide the limiting slider, preventing the protective baffle from shifting or shaking during use.

[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: the smart lock password is the key information for unlocking the door lock, and the password is easily leaked when it is not covered during input. Furthermore, when staff operate the keypad, the relevant information may be accidentally seen by others, forcing staff to change the password of the smart lock itself. Therefore, to address the above problems, an anti-peeping smart fingerprint lock is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where staff may accidentally have their information seen while operating the keypad, forcing them to change the password of the smart lock. This invention proposes a privacy-protecting smart fingerprint lock.

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: an anti-peeping smart fingerprint lock, including a smart lock body 1, a keypad screen 2 mounted on the surface of the smart lock body 1, a door handle 5 mounted on the surface of the smart lock body 1, a fingerprint scanner 6 mounted on the surface of the door handle 5, and an anti-peeping device 3 on the surface of the smart lock body 1. By setting the anti-peeping device 3, the effect of reducing people peeping at the keypad screen 2 is achieved, avoiding the situation where the staff accidentally sees the relevant information when operating the keypad screen 2, which would force the staff to change the password of the smart lock body 1, thus improving the security of the device. Protective devices 4 are set on both sides of the door handle 5, which achieves the effect of protecting the fingerprint scanner 6, preventing the fingerprint scanner from being exposed to the air for a long time and the surface of the fingerprint scanner 6 from being covered with fine dust, which would cause the fingerprint scanner 6 to malfunction when the staff scans fingerprints, thus improving the practicality of the device.

[0032] The specific settings and functions of its anti-peeping device 3 and protective device 4 will be explained below.

[0033] Reference Figure 2, Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in this embodiment: the anti-peeping device 3 includes four single-arc plates 301, all of which are fixedly connected to the surface of the smart lock body 1. The four single-arc plates 301 are arranged in pairs, and a rotating rod 302 is fixedly connected to the side of each pair of single-arc plates 301 that is close to each other. A baffle 303 is rotatably connected to the arc surface of the rotating rod 302. A U-shaped frame 305 is fixedly connected to one side of the baffle 303. A limit plate 304 is rotatably connected to the surface of the smart lock body 1. Two torsion springs 314 are sleeved on the arc surface of the rotating rod 302. The two ends of the torsion springs 314 are fixedly connected to the single-arc plates 301 and the baffle 303, respectively. When the operator needs to perform related operations on the keypad 2, the operator first rotates the limit plate 304 on the inner surface of the U-shaped frame 305. Rotate until the limit plate 304 is completely disengaged from the U-shaped frame 305. At this time, the torque of the torsion spring 314 drives the baffle 303 to rotate on the arc surface of the rotating rod 302 until the baffle 303 opens. Then, the staff can perform corresponding operations on the keypad 2. This achieves the effect of automatically opening the baffle 303, reducing the number of operation steps for the staff and improving their work efficiency. A shaped compartment 306 is fixedly connected to the surface of the smart lock body 1. Connecting rods 307 are fixedly connected to both sides of the shaped compartment 306. A double arc plate 308 is rotatably connected to the end of the connecting rod 307 away from the shaped compartment 306. A cover plate 309 is fixedly connected to the side of the two double arc plates 308 that are close to each other. A cleaning pad 31 is slidably connected inside the shaped compartment 306. 0. When staff need to clean their fingers, they first rotate the cover plate 309 and slide it on the surface of the irregularly shaped compartment 306. The cover plate 309 drives the double arc plate 308 to rotate at one end of the connecting rod 307 until the cover plate 309 is fully open. At this time, staff can wipe the cleaning pad 310 with their fingers, achieving the effect of cleaning their fingers. This prevents the keypad 2 from being contaminated by oil, water stains, etc., when staff operate it. Square plates 311 are fixedly connected to both sides of the irregularly shaped compartment 306. Threaded rods 312 are inserted into the internal threads of the square plates 311. Grooves are provided on both sides of the irregularly shaped compartment 306, and fixed plates 31 are slidably connected to the surface of the grooves of the irregularly shaped compartment 306. 3. The fixing plate 313 is rotatably connected to one end of the threaded rod 312. When the worker needs to replace the cleaning pad 310, the worker first rotates the threaded rod 312 within the square plate 311. The threaded rod 312 drives the fixing plate 313 to slide on the surface of the groove in the irregularly shaped compartment 306 until the fixing plate 313 is completely detached from the surface of the cleaning pad 310. At this point, the worker can pull the cleaning pad 310 to slide within the irregularly shaped compartment 306 until the cleaning pad 310 is completely detached from the irregularly shaped compartment 306. Then, the worker can replace it with a new cleaning pad 310 and place it in the irregularly shaped compartment 306. Then, the worker rotates the threaded rod 312 to move the fixing plate 313 until the fixing plate 313 is in contact with the surface of the cleaning pad 310.The worker then continues to rotate the threaded rod 312 within the square plate 311 until the fixing plate 313 presses against the cleaning pad 310. This achieves the effect of replacing the cleaning pad 310, preventing its cleaning function from decreasing due to prolonged use.

[0034] Reference Figure 7 As shown, specifically, the protective device 4 includes two side plates 41, which are fixedly connected to both sides of the door handle 5. Sliding rods 42 are slidably inserted into the side plates 41. Protective covers 43 are fixedly connected to one end of each sliding rod 42. Pushing blocks 44 are fixedly connected to the surface of the protective covers 43. A first spring 45 is fitted onto the arc surface of the sliding rods 42. The two ends of the first spring 45 are fixedly connected to the protective covers 43 and the side plates 41, respectively. When a staff member needs to use the door handle 5, the staff member first pulls the pushing block 44, causing the protective cover 43 to slide on the surface of the door handle 5. At this time, the first spring 45 is stretched, and the protective cover 43 causes the sliding rods 42 to slide within the side plates 41 until the fingerprint scanner 6 is fully open. The staff member can then scan their fingerprint. Then, the staff member releases the pushing block 44. The rebound force of the first spring 45 causes the protective cover 43 to move, and the protective cover 43 causes the sliding rods 42 to slide within the side plates 41 until the protective cover 43 completely covers the fingerprint scanner 6. This design improves the stability of the protective cover 43, preventing it from shaking when the door is closed after use and causing it to slide on the surface of the door handle 5. The size of the protective cover 43 matches the size of the handle 5. A circular plate 46 is fixedly connected to the surface of the connecting groove of the sliding rod 42. When the staff needs to use the smart lock body 1, they first pull the push block 44 to make the protective cover 43 slide on the surface of the door handle 5. At this time, the first spring 45 is stretched, and the protective cover 43 drives the sliding rod 42 to slide inside the side plate 41. The sliding rod 42 drives the circular plate 46 to move until the circular plate 46 is in contact with the surface of the side plate 41 and the protective cover 43 is fully opened without affecting the use of the fingerprint scanner 6. At this time, the staff can use the fingerprint scanner 6 normally. This design prevents the staff from using too much force when pulling the protective cover 43, which could cause the sliding rod 42 to be pulled off the side plate 41 and require a second installation.

[0035] Working principle: When the operator needs to operate the keypad 2, the operator first rotates the limiting plate 304 on the inner surface of the U-shaped frame 305 until the limiting plate 304 is completely disengaged from the U-shaped frame 305. At this time, the torque of the torsion spring 314 drives the baffle 303 to rotate on the arc surface of the rotating rod 302 until the baffle 303 opens. Then the operator can operate the keypad 2 accordingly. When the operator needs to clean their fingers, the operator first rotates the cover plate 309 and slides it on the surface of the irregularly shaped compartment 306. The cover plate 309 drives the double arc plate 308 to rotate at one end of the connecting rod 307 until the cover plate 309 is fully opened. At this time, the operator can wipe the cleaning pad 310 with their fingers. When the operator needs to replace the cleaning pad 310, the operator first rotates the threaded rod 312 inside the square plate 311. The threaded rod 312 drives the fixing plate 31 3. Slide the cleaning pad 310 on the surface of the groove in the irregularly shaped compartment 306 until the fixing plate 313 is completely detached from the surface of the cleaning pad 310. At this time, the staff can pull the cleaning pad 310 to slide inside the irregularly shaped compartment 306 until the cleaning pad 310 is completely detached from the irregularly shaped compartment 306. Then the staff can replace it with a new cleaning pad 310 and place it inside the irregularly shaped compartment 306. Then the staff rotates the threaded rod 312 to move the fixing plate 313 until the fixing plate 313 is in contact with the surface of the cleaning pad 310. Then the staff continues to rotate the threaded rod 312 inside the square plate 311 until the fixing plate 313 squeezes the cleaning pad 310. At this time, the effect of reducing the number of people peeking at the keypad 2 is achieved, avoiding the situation where the staff accidentally sees the relevant information when operating the keypad 2, which would force the staff to change the password of the smart lock body 1, thus improving the security of the device.

[0036] When a staff member needs to use the door handle 5, the staff member first pulls the push block 44 to make the protective cover 43 slide on the surface of the door handle 5. At this time, the first spring 45 is stretched, and the protective cover 43 makes the slide rod 42 slide inside the side plate 41. The slide rod 42 makes the circular plate 46 move until the circular plate 46 is in contact with the surface of the side plate 41, until the fingerprint scanning port 6 is fully open. At this time, the staff member can scan the fingerprint. Then the staff member releases the push block 44. At this time, the rebound force of the first spring 45 makes the protective cover 43 move. The protective cover 43 makes the slide rod 42 slide inside the side plate 41 until the protective cover 43 completely covers the fingerprint scanning port 6. At this time, the fingerprint scanning port 6 is protected, avoiding the fingerprint scanner from being exposed to the air for a long time. The surface of the fingerprint scanning port 6 is covered with fine dust, which may cause the fingerprint scanning port 6 to malfunction when the staff member scans the fingerprint, thus improving the practicality of the device.
