Description

Technical Field

[0001] This utility model relates to a waterproof smart door lock, and more particularly to a waterproof smart door lock, belonging to the technical field of waterproof smart door locks. Background Technology

[0002] Smart locks are improved versions of traditional mechanical locks, typically featuring a range of unlocking methods such as fingerprint, facial recognition, button, and key. They offer greater intelligence and convenience in terms of user security, identification, and management. Smart locks are the locking mechanism in access control systems. Unlike traditional mechanical locks, smart locks are composite locks that combine security, convenience, and advanced technology.

[0003] Existing smart locks have a simple structure. While traditional smart locks offer users many conveniences in terms of unlocking methods, most smart locks have extremely poor waterproof performance, or even lack waterproof structure. In rainy or humid environments, users may encounter problems such as the lock not recognizing fingerprints or invalid password input. In damp or rainy environments, the lock's circuitry may be more prone to failure, causing the lock to fail to open or close properly, thus posing a security risk to homes or offices.

[0004] Therefore, there is an urgent need to improve a waterproof smart door lock to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof smart door lock. By incorporating a waterproof structure into the original lock body, it prevents poorly waterproof or non-waterproof lock bodies from being corroded by rain or humid environments, thus avoiding problems such as fingerprint recognition failure and invalid password input. When the lock body is not in use, the waterproof shell covers and seals the password input area and fingerprint recognition area. When the waterproof shell is on the lock body, the retaining plate engages with the second groove on the fixing strip under the elastic action of the first spring, securing the waterproof shell and preventing it from shaking. Pulling the waterproof shell... When the locking plate is squeezed, it disengages from the second slot, allowing the waterproof shell to be pulled upwards and opened. When the first slot on the fixing strip moves to the position of the locking plate, the locking plate will pop out again under the elastic action of the first spring and engage inside the first slot, thus securing the waterproof shell after it is pulled open to prevent it from slipping. This allows users to unlock the door without manually supporting the waterproof shell, making it easier for people to unlock. The advantage of this structure is that it provides excellent waterproofing for the door lock body and makes it easy to open the waterproof shell. This prevents the electrical circuit of the door lock body from malfunctioning in humid or rainy environments, which could cause the door lock to fail to open or close properly and pose no safety hazards to homes or offices.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A waterproof smart door lock includes a lock body and a handle. The lock body has a fingerprint recognition area and a mechanical keyhole. The lock body also has a waterproof structure, which includes a waterproof shell movably mounted on the lock body. A groove is formed on the top of the lock body. A first fixing rod connected to the lock body is fixedly installed inside the groove. A locking plate is movably mounted on the first fixing rod. A first spring connected to the lock body is also provided on the first fixing rod. Multiple fixing strips are fixedly installed on the inner side of the waterproof shell. Each fixing strip has a first slot and a second slot that cooperate with the locking plate.

[0008] Preferably, the door lock body has multiple sliding grooves, and a sliding rod connected to the waterproof shell is movably installed inside the sliding groove.

[0009] Preferably, a plurality of fixing blocks are fixedly installed at one end of the waterproof shell, a second fixing rod is fixedly installed on one side of the fixing blocks, a plurality of mounting holes are provided on the second fixing rod, a second spring is fixedly installed inside the mounting holes, a locking block is fixedly installed at one end of the second spring, a fixing plate is fixedly installed on the door lock body, a plurality of insertion holes adapted to the second fixing rod are provided on the fixing plate, and a plurality of locking holes for cooperating with the locking block are provided inside the insertion holes.

[0010] Preferably, one end of the card block is curved.

[0011] Preferably, a rotating ring is installed inside the mechanical keyhole, a telescopic rod is provided on the top of the rotating ring, a sealing cover is fixedly installed on the top of the telescopic rod, and a pull ball is fixedly installed on the sealing cover.

[0012] Preferably, a plurality of limiting plates are fixedly installed on the waterproof shell, a finger cleaning machine is provided at one end of the limiting plate, and a movable block connected to the limiting plate is fixedly installed at the bottom of the finger cleaning machine.

[0013] Preferably, a rod connected to the movable block is movably mounted on the limiting plate, and a third spring connected to the limiting plate is wound around the rod.

[0014] This utility model has at least the following beneficial effects:

[0015] By installing a waterproof structure, a waterproof structure is installed on the original door lock body, preventing some door lock bodies with poor waterproof performance or no waterproof effect from being corroded by rain or humid environments. This effectively avoids problems such as the door lock body being unable to recognize fingerprints or invalid password input.

[0016] In this technical solution, when the door lock body is not in use, the waterproof shell covers the door lock body and seals the password input area and fingerprint recognition area. When the waterproof shell covers the door lock body, the locking plate will engage with the second groove on the fixing strip under the elastic action of the first spring, which can fix the waterproof shell and prevent it from shaking.

[0017] In this technical solution, when the waterproof shell is pulled, the locking plate is squeezed and disengages from the second slot, allowing the waterproof shell to be pulled upwards and opened. When the first slot on the fixing strip moves to the position of the locking plate, the locking plate will pop out again under the elastic action of the first spring and engage inside the first slot, thus securing the waterproof shell after it is pulled open to prevent it from slipping. This allows users to unlock the door without manually supporting the waterproof shell, making it easier for people to unlock. The advantage of this structure is that it provides excellent waterproofing for the door lock body and makes it easy to open the waterproof shell. It also prevents the door lock body's circuit from malfunctioning in humid or rainy environments, which could cause the door lock to fail to open or close properly and pose no safety hazards to homes or offices.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-10 As shown in the figure, this embodiment provides a waterproof smart door lock embodiment.

[0032] A waterproof smart door lock includes a door lock body 1 and a handle 2. The door lock body 1 is provided with a fingerprint recognition area 3 and a mechanical keyhole 4. The door lock body 1 is provided with a waterproof structure 5, which includes a waterproof shell 6 movably installed on the door lock body 1. A groove 7 is opened on the top of the door lock body 1. A first fixing rod 8 connected to the door lock body 1 is fixedly installed inside the groove 7. A card plate 9 is movably installed on the first fixing rod 8. A first spring 10 connected to the door lock body 1 is provided on the first fixing rod 8. Multiple fixing strips 11 are fixedly installed on the inner side of the waterproof shell 6. The fixing strips 11 are respectively provided with a first slot 12 and a second slot 13 that cooperate with the card plate 9. By setting up the waterproof structure 5, a waterproof structure is installed on the original door lock body 1, which avoids the door lock body 1 with poor waterproof performance or no waterproof effect from being corroded by rain or humid environment, thus causing problems such as the door lock body 1 being unable to recognize fingerprints or invalid password input.

[0033] When the door lock body 1 is not in use, the waterproof shell 6 covers the door lock body 1 and seals the password input area and fingerprint recognition area 3. When the waterproof shell 6 covers the door lock body 1, the locking plate 9 will engage with the second slot 13 on the fixing strip 11 under the elastic action of the first spring 10, which can fix the waterproof shell 6 and prevent it from shaking. When the waterproof shell 6 is pulled, the locking plate 9 will be squeezed out of the second slot 13, thereby allowing the waterproof shell 6 to be pulled upward to open. When the first slot 12 on the fixing strip 11 moves to the position of the locking plate 9... When the first spring 10 is in motion, the card plate 9 will pop out again and engage inside the first slot 12, which can pull the waterproof shell 6 open and fix it to prevent it from slipping. This makes it convenient for users to unlock without having to manually support the waterproof shell 6. The advantage of this structure is that it can provide a good waterproof effect for the door lock body 1 and also makes it easy to open the waterproof shell 6. This prevents the circuit of the door lock body 1 from malfunctioning in humid or rainy environments, which would cause the door lock to be unable to open or close normally and would not bring any safety hazards to the home or office.

[0034] like Figure 8 As shown, the door lock body 1 has multiple sliding grooves 14. Inside the sliding grooves 14, sliding rods 15 connected to the waterproof shell 6 are movably installed. By setting the sliding grooves 14 and sliding rods 15, the friction between the waterproof shell 6 and the door lock body 1 can be reduced, making the waterproof shell 6 slide more smoothly on the door lock body 1. This not only makes it easier for users to open the waterproof shell 6, but also reduces the wear between the waterproof shell 6 and the door lock body 1.

[0035] like Figure 8As shown, a plurality of fixing blocks 16 are fixedly installed at one end of the waterproof shell 6. A second fixing rod 17 is fixedly installed on one side of the fixing block 16. A plurality of mounting holes 18 are provided on the second fixing rod 17. A second spring 19 is fixedly installed inside the mounting hole 18. A locking block 20 is fixedly installed at one end of the second spring 19. A fixing plate 21 is fixedly installed on the door lock body 1. A plurality of insertion holes 22 adapted to the second fixing rod 17 are provided on the fixing plate 21. A plurality of locking holes 22 are provided inside the insertion holes 22 for use with the locking block 20. The door lock body 1 is connected by the fixing block 16, the second fixing rod 17, the mounting hole 18, the second spring 19, the locking block 20, the fixing plate 21, the insertion hole 22, and the locking block 20. The hole is designed so that when the waterproof shell 6 is closed, the second fixing rod 17 can be inserted into the hole 22. When the second fixing rod 17 is inserted into the fixing plate 21, the locking block 20 will be squeezed and retracted into the mounting hole 18. When the locking block 20 moves to the position of the locking hole, the locking block 20 can be popped out and locked into the hole under the elastic action of the second spring 19, thereby fixing the second fixing rod 17 into the hole 22. Therefore, the stability of the waterproof shell 6 covering the door lock body 1 can be improved. When the waterproof shell 6 is pulled, the locking block 20 is squeezed and retracted into the mounting hole 18, and the second fixing rod 17 can be pulled out from the hole 22, so that the waterproof shell 6 can be opened normally.

[0036] like Figure 8 As shown, one end of the locking block 20 is set to be arc-shaped. By setting one end of the locking block 20 to be arc-shaped, the friction of one end of the locking block 20 can be reduced, making the locking block 20 slide more smoothly on the inner wall of the insertion hole 22, thereby facilitating the disassembly and installation of the second fixing rod 17.

[0037] like Figure 9 As shown, a rotating ring 23 is installed inside the mechanical keyhole 4. A telescopic rod 24 is set on the top of the rotating ring 23. A sealing cover 25 is fixedly installed on the top of the telescopic rod 24. A pull ball 26 is fixedly installed on the sealing cover 25. With the arrangement of the rotating ring 23, telescopic rod 24, sealing cover 25 and pull ball 26, when the door lock body 1 is unexpectedly without power, the pull ball 26 can be pulled to extend the telescopic rod 24, thereby opening the sealing cover 25. Then, by rotating the sealing cover 25, the keyhole position on the mechanical keyhole 4 can be opened, and the key can be inserted to open the door lock body 1. Rotating the sealing cover 25 to reset it and then pressing the sealing cover 25 can lock it onto the mechanical keyhole 4, thereby completing the sealing of the mechanical keyhole 4 and preventing the mechanical keyhole 4 from getting wet and rusting, which would make it unusable.

[0038] like Figure 10As shown, multiple limiting plates 27 are fixedly installed on the waterproof shell 6. A finger cleaning device 28 is provided at one end of the limiting plate 27. A movable block 29 connected to the limiting plate 27 is fixedly installed at the bottom of the finger cleaning device 28. With the setting of the limiting plate 27, the finger cleaning device 28 and the movable block 29, when the user uses fingerprint unlocking, he can first put his finger into the inside of the finger cleaning device 28 for cleaning and drying. This can prevent dirt on the finger from remaining on the fingerprint recognition area 3, prevent criminals from copying the fingerprint to open the door lock body 1, and avoid property loss.

[0039] As shown in the first spring 10, a plug rod 30 connected to the moving block 29 is movably installed on the limiting plate 27. A third spring 31 connected to the limiting plate 27 is wound around the plug rod 30. With the setting of the plug rod 30 and the third spring 31, the plug rod 30 is engaged inside the moving block 29 under the elastic action of the third spring 31, thereby fixing the finger cleaning machine 28 on the limiting plate 27 to prevent it from falling off. After pulling the plug rod 30 to disengage it from inside the moving block 29, the finger cleaning machine 28 can be disassembled, thus facilitating the disassembly and maintenance of the finger cleaning machine 28 by personnel.

[0040] In this embodiment, as Figures 1-10 As shown, the working process of a waterproof smart door lock provided in this embodiment is as follows:

[0041] When the door lock body 1 is not in use, the waterproof shell 6 covers the door lock body 1 and seals the password input area and fingerprint recognition area 3. When the waterproof shell 6 covers the door lock body 1, the locking plate 9 will engage with the second slot 13 on the fixing strip 11 under the elastic action of the first spring 10, which can fix the waterproof shell 6 and prevent it from shaking. When the waterproof shell 6 is pulled, the locking plate 9 will be squeezed out of the second slot 13, thereby allowing the waterproof shell 6 to be pulled upward to open. When the first slot 12 on the fixing strip 11 moves to the position of the locking plate 9... When the first spring 10 is in motion, the card plate 9 will pop out again and engage inside the first slot 12, which can pull the waterproof shell 6 open and fix it to prevent it from slipping. This makes it convenient for users to unlock without having to manually support the waterproof shell 6. The advantage of this structure is that it can provide a good waterproof effect for the door lock body 1 and also makes it easy to open the waterproof shell 6. This prevents the circuit of the door lock body 1 from malfunctioning in humid or rainy environments, which would cause the door lock to be unable to open or close normally and would not bring any safety hazards to the home or office.

[0042] In summary, according to this embodiment, the waterproof smart door lock, through the setting of the sliding groove 14 and the sliding rod 15, can reduce the friction between the waterproof shell 6 and the door lock body 1, making the sliding of the waterproof shell 6 on the door lock body 1 smoother. This not only makes it easier for the user to open the waterproof shell 6, but also reduces the wear between the waterproof shell 6 and the door lock body 1. Through the setting of the fixing block 16, the second fixing rod 17, the mounting hole 18, the second spring 19, the locking block 20, the fixing plate 21, the insertion hole 22, and the locking hole, when the waterproof shell 6 is closed, the second fixing rod 17 can be inserted into the insertion hole 22. When the second fixing rod 17 is inserted into the fixing plate 21, the locking block 20 will be squeezed and contracted into the mounting hole 18. When the locking block 20 moves to the position of the locking hole, the locking block 20 can be popped out and locked in the interior under the elastic action of the second spring 19, thereby fixing the second fixing rod 17 inside the insertion hole 22. Therefore, the stability of the waterproof shell 6 covering the door lock body 1 can be improved.

[0043] When the waterproof shell 6 is pulled, the locking block 20 is squeezed and retracted into the mounting hole 18, so that the second fixing rod 17 can be pulled out from the insertion hole 22, and the waterproof shell 6 can be opened normally. The arc-shaped design of one end of the locking block 20 can reduce the friction at one end of the locking block 20, making the locking block 20 slide more smoothly on the inner wall of the insertion hole 22, thus facilitating the disassembly and installation of the second fixing rod 17.

[0044] With the arrangement of the rotating ring 23, telescopic rod 24, sealing cover 25 and pull ball 26, when the door lock body 1 unexpectedly loses power, the telescopic rod 24 can be extended by pulling the pull ball 26, thereby opening the sealing cover 25. Then, by rotating the sealing cover 25, the keyhole position on the mechanical keyhole 4 can be opened, and the key can be inserted to open the door lock body 1. Rotating the sealing cover 25 to reset it and then pressing the sealing cover 25 will lock it onto the mechanical keyhole 4, thereby sealing the mechanical keyhole 4 and preventing the mechanical keyhole 4 from getting wet and rusting, which would render it unusable.

[0045] With the setting of the limiting plate 27, the finger cleaner 28, and the moving block 29, before the user uses fingerprint unlocking, they can first insert their finger into the inside of the finger cleaner 28 to clean and dry it. This can prevent dirt on the finger from remaining on the fingerprint recognition area 3, preventing criminals from copying the fingerprint to open the door lock body 1 and avoid property loss. With the setting of the insertion rod 30 and the third spring 31, the insertion rod 30 is engaged inside the moving block 29 under the elastic action of the third spring 31, thereby fixing the finger cleaner 28 on the limiting plate 27 to prevent it from falling off. After pulling the insertion rod 30 to disengage it from the inside of the moving block 29, the finger cleaner 28 can be disassembled, which facilitates the disassembly and maintenance of the finger cleaner 28.
