Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to a convenient and secure smart lock. Background Technology

[0002] A smart lock consists of a mechanical lock cylinder and lock body, and an electronic control board and power module. Smart locks provide residents with convenient unlocking methods such as fingerprints, passwords, and card swipes, avoiding the inconvenience and easy loss associated with traditional keys.

[0003] Chinese patent application CN201921305317.0 discloses a smart lock. The key technical points of the solution are: the smart lock provided by this utility model has a cover that slides up and down to open and close. When it is closed, the protruding teeth on the slide bar will engage with the limiting groove in the slide groove to restrict the movement of the cover. The spring will apply force to the slide bar to make the slide bar and the cover tightly engaged. When it is necessary to open the cover, the pressing column is operated to lift the lower end of the slide bar, so that the engagement between the protruding teeth and the limiting groove is separated, thus allowing the cover to move upward. The operation is also very convenient. Two fingers can be used to press the two pressing columns respectively and lift the cover upward. The above technical solution enhances the security of opening the cover.

[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: smart locks provide residents with convenient unlocking methods, such as fingerprints, passwords, and card swiping, avoiding the problems of inconvenience and easy loss of traditional keys. After staff members use the fingerprint reader, non-staff members can copy the staff member's fingerprint and use the staff member's fingerprint to unlock the smart lock. Therefore, a convenient and secure smart lock is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, after a staff member has used a fingerprint reader, a non-staff member can copy the staff member's fingerprint and use it to unlock the smart lock. This invention proposes a convenient and secure smart lock.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a convenient and safe smart lock, comprising a smart lock body, a handle mounted on the surface of the smart lock body, a fingerprint reader mounted on the surface of the handle, an emergency charging port mounted on one side of the smart lock body, and cleaning devices provided on both sides of the handle.

[0011] The aforementioned components achieve the following effect: they provide a stable connection to the limit rod, preventing the limit rod from detaching from the L-shaped plate due to shaking caused by the operator using the handle, thus improving the stability of the device.

[0012] Preferably, the arc surface of the support rod is rotatably connected to a rotating ring, one side of the rotating ring is fixedly connected to the push plate, and the surface of the long block is provided with a recycling hole.

[0013] The effect achieved by the above-mentioned components is to achieve the effect of rotating and retracting the limit rod, thus avoiding the situation where the limit rod touches the sliding L-shaped plate being retracted due to the up-and-down shaking of the limit rod when the staff has finished cleaning the fingerprint reader, which would cause wear on the limit rod and make it unusable.

[0014] Preferably, a protective device is provided on one side of the smart lock body. The protective device includes a support block, which is fixedly connected to one side of the smart lock body.

[0029] Reference Figure 1As shown, this utility model provides a technical solution: a convenient and safe smart lock, including a smart lock body 1, a handle 2 mounted on the surface of the smart lock body 1, a fingerprint reader 3 mounted on the surface of the handle 2, an emergency charging port 4 mounted on one side of the smart lock body 1, and cleaning devices 5 on both sides of the handle 2. By setting the cleaning devices 5, the surface of the fingerprint reader 3 is cleaned, preventing unauthorized personnel from copying the fingerprints of staff members after they have used the fingerprint reader 3, thereby unlocking the smart lock body 1 with the staff member's fingerprint, thus improving the security of the device. A protective device 6 is set on one side of the smart lock body 1, which protects the emergency charging port 4, preventing it from being damaged due to blockage or moisture when staff members need to use it, thus making the emergency charging port 4 unusable and the smart lock body 1 unusable, thereby improving the practicality of the device.

[0030] The specific setup and function of its cleaning device 5 and protective device 6 will be explained below.

[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the cleaning device 5 includes two connecting blocks 501, which are fixedly connected to both sides of the handle 2. A long rod 502 is fixedly connected to one side of each connecting block 501. A sliding wiper 503 is slidably connected to the arc surface of the two long rods 502. An L-shaped plate 504 is fixedly connected to one side of the sliding wiper 503. A cleaning block 505 is fixedly connected to one side of the L-shaped plate 504. A baffle 507 is fixedly connected to one end of each long rod 502. A first spring 506 is fixedly connected to one side of the baffle 507. One end of the first spring 506 is fixedly connected to the sliding wiper 503. A long block 508 is fixedly connected to one side of the baffle 507. A support rod 509 is fixedly connected to the surface of the long block 508. A push plate 511 is slidably connected to the arc surface of the support rod 509. A screw plate 512 is fixedly connected to one end of the support rod 509. A limiting rod 513 is slidably inserted into the push plate 511. A circular plate 515 is fixedly connected to one end of the limiting rod 513. A limiting hole is opened on one side of the L-shaped plate 504. After the staff finishes cleaning the fingerprint reader 3, the staff pushes the circular plate 515 to drive the limiting rod 513 to slide within the push plate 511 until the limiting rod 513 is inserted into the limiting hole on one side of the L-shaped plate 504. This achieves the effect of limiting the cleaning block 505, preventing the cleaning block 505 from moving back and forth due to shaking caused by external factors when the staff needs to unlock the fingerprint reader 3, thus affecting the staff's unlocking. The arc surface of the limiting rod 513 is fitted with a second spring 514. The two ends of the second spring 514 are fixedly connected to the push plate 511 and the circular plate 515, respectively. By releasing the circular plate 515, the rebound force of the second spring 514 drives the circular plate 515, which in turn drives the limiting rod 513 to slide within the push plate 511 until the limiting rod 513 is inserted into the limiting hole on one side of the L-shaped plate 504. This achieves a stable connection of the limiting rod 513, preventing the limiting rod 513 from disengaging from the L-shaped plate 504 due to shaking caused by the operator using the handle 2, thus improving the stability of the device. The arc surface of the support rod 509 is rotatably connected to a rotating ring 510, one side of which is fixedly connected to the push plate 511. The surface of the elongated block 508 has a retrieval hole. After the L-shaped plate 504 is released from its limiting position, rotating the rotating ring 510 causes the pushing plate 511 to rotate, which in turn causes the limiting rod 513 to rotate until it is perpendicular to the retrieval hole on the surface of the elongated block 508. Then, the circular plate 515 is pushed, causing the limiting rod 513 to slide within the pushing plate 511 until it inserts into the retrieval hole on the surface of the elongated block 508. This achieves the effect of rotating and retrieving the limiting rod 513, preventing it from wobbling and colliding with the retrieving sliding L-shaped plate 504 during cleaning of the fingerprint reader 3, thus avoiding wear on the limiting rod 513.This results in the limit lever 513 becoming unusable.

[0032] Reference Figure 4 and Figure 5 As shown, specifically, the protective device 6 includes a support block 601, which is fixedly connected to one side of the smart lock body 1. A rotating rod 602 is rotatably connected inside the support block 601. Strip plates 604 are fixedly connected to both ends of the rotating rod 602. A protective plate 605 is fixedly connected to one side of the two strip plates 604. A square block 606 is fixedly connected to one side of the protective plate 605. A fixing hole is opened on one side of the square block 606. A fixing block 608 is fixedly connected to the side of the smart lock body 1 near the support block 601. A connecting rod 609 is fixedly connected to one side of the fixing block 608. A strip plate 610 is rotatably connected to the arc surface of the connecting rod 609. A fixing rod 611 is slidably inserted into the strip plate 610. Two torsion springs 603 are sleeved on the arc surface of the rotating rod 602. The two ends of the torsion springs 603 support the block 601 respectively. The strip plate 604 is fixedly connected to the protective plate 605. When the fixing of the protective plate 605 is released, the torque of the torsion spring 603 drives the strip plate 604, and the strip plate 604 drives the protective plate 605 to rotate until the protective plate 605 is fully opened, achieving the effect of quickly opening the protective plate 605. This reduces the number of operation steps for the staff, increases the work efficiency of the staff, and improves the convenience of the device. A positioning plate 607 is fixedly connected to one side of the square block 606. The size of the fixing rod 611 is adapted to the size of the fixing hole of the square block 606. By rotating the strip plate 610, the fixing rod 611 is driven to rotate until the fixing rod 611 touches the positioning plate 607, achieving the effect of quickly positioning the fixing rod 611. This allows the staff to quickly protect the emergency charging port 4, thereby reducing the amount of dust or debris falling into the emergency charging port 4.

[0033] Working principle: After the L-shaped plate 504 is released from its limiting position, the rotating ring 510 is rotated, which drives the push plate 511 to rotate. The push plate 511 drives the limiting rod 513 to rotate until the limiting rod 513 is perpendicular to the recycling hole on the surface of the long block 508. Then, the circular plate 515 is pushed, and the circular plate 515 drives the limiting rod 513 to slide within the push plate 511 until the limiting rod 513 is inserted into the recycling hole on the surface of the long block 508. By pulling the sliding wiper 503, the sliding wiper 503 stretches the first spring 506, and the sliding wiper 503 drives the L-shaped plate 504, which in turn drives the cleaning block 505. The cleaning process continues until the cleaning block 505 adheres to the surface of the fingerprint reader 3, completing the wiping. By releasing the circular plate 515, the rebound force of the second spring 514 drives the circular plate 515, which in turn drives the limiting rod 513 to slide within the push plate 511 until the limiting rod 513 is inserted into the limiting hole on one side of the L-shaped plate 504. By setting up the cleaning device 5, the surface of the fingerprint reader 3 is cleaned, preventing unauthorized personnel from copying the fingerprints of staff members after they have used the fingerprint reader 3, and thus using the staff member's fingerprint to unlock the smart lock body 1, thereby improving the security of the device.

[0034] By pushing the protective plate 605 until it fits against the emergency charging port 4, and then rotating the strip plate 610 to rotate the fixing rod 611 until it touches the positioning plate 607, the fixing rod 611 is then pushed to slide within the strip plate 610 until it is inserted into the fixing hole on one side of the square block 606. After the protective plate 605 is released, the torque of the torsion spring 603 drives the strip plate 604, which in turn drives the protective plate 605 to rotate until it is fully opened. By setting the protective device 6, the emergency charging port 4 is protected, preventing it from being damaged by debris or moisture when the staff needs to use it. This would make the emergency charging port 4 unusable and consequently the smart lock body 1 unusable, thus improving the practicality of the device.
