Description

Technical Field

[0001] This utility model relates to the field of smart door lock technology, specifically to a smart lock that can monitor the closed status of a door. Background Technology

[0002] With the rapid development of smart homes, smart locks have gradually become common devices in homes and offices due to their convenience and security. However, most existing smart locks focus on diversifying unlocking methods, such as fingerprint recognition and password input, while neglecting effective monitoring of the door's closed status.

[0003] In practical use, users often find that doors are not fully closed, which not only poses a safety hazard but may also cause energy waste (such as leakage of cool air from indoor air conditioners). Some users install separate door magnetic sensors to monitor the door status, but this method increases equipment cost and installation complexity, and requires additional network configuration and power supply. In addition, the camera angle of traditional smart locks is fixed, making it difficult to fully capture the surrounding environment of the door and accurately determine whether the door is closed. Therefore, those skilled in the art have provided a smart lock that can monitor the door's closed status to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a smart lock with a simple structure and reasonable design that can monitor the closed status of the door in order to solve the above problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: it includes a lock body and a monitoring camera, characterized in that: the monitoring camera is installed at the upper middle position of the front side wall of the lock body, a concave connecting seat is fixedly installed on the front side wall of the lock body and on one side of the monitoring camera, and a lens is fixedly installed on the inner side wall of the concave connecting seat, the lens cooperating with the monitoring camera.

[0006] As a further optimization of this utility model, the top of the concave connecting seat is threaded with a nut for fixing the lens, and a protective plate is fixedly installed on the top of the concave connecting seat.

[0007] As a further optimization of this utility model, a signal module is fixedly installed on the rear side wall of the lock body and located directly behind the monitoring camera, and the signal module is electrically connected to the monitoring camera.

[0008] As a further optimization of this utility model, a speaker is installed on the inner side wall of the lock body, and a password unlocking area is installed on the front side wall of the lock body below the speaker. The speaker is electrically connected to the signal module.

[0009] As a further optimization of this utility model, a first door handle is rotatably connected to the lower middle position of the front side wall of the lock body, and a second door handle is rotatably connected to the rear side wall of the lock body and located directly behind the first door handle. The first door handle and the second door handle are connected by a square bar.

[0010] As a further optimization of this utility model, a lock tongue is slidably connected through the side wall of the lock body and located between the first door handle and the second door handle, and the lock tongue is connected to the square bar through a transmission paddle.

[0011] As a further optimization of this utility model, a fingerprint area is provided on one side of the front wall of the first door handle.

[0012] As a further optimization of this utility model, a battery compartment is fixedly installed in the middle of the rear side wall of the lock body. The battery compartment is electrically connected to the monitoring camera, signal module, password unlocking area, speaker and fingerprint area respectively.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the cooperation of a lens and a monitoring camera, with the lens at a 30-degree angle to the door, can obtain the door's status information from all directions by combining the monitoring range of the camera with the reflection of the lens. It uses image recognition technology to achieve accurate judgment of the door's closing status, effectively avoiding safety hazards and energy waste caused by the door not being closed properly.

[0015] 2. This utility model utilizes a monitoring camera with a lens to acquire images of the environment around the door, and then uses a signal module to transmit the images to a user terminal or smart home control system. The image recognition algorithm is used to analyze and determine whether the door is closed. This image recognition-based monitoring method can accurately capture the door's status information, replacing the function of a door magnetic sensor that determines the door's opening and closing status through magnetic induction.

[0016] 3. With this utility model, when the door is not closed, the speaker and mobile application will promptly issue a reminder to ensure that the user can deal with the door status problem in a timely manner, thereby improving home security and user experience. Attached Figure Description

Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the heat shrink tubing metering and winding device comprises a lock body 1, a password unlocking area 2, a first door handle 3, a second door handle 4, a bolt 5, a fingerprint area 6, a battery compartment 7, a speaker 8, a protective plate 9, a concave connecting seat 10, a lens 11, a monitoring camera 12, and a signal module 13. The lock body 1 serves as the main body of the smart lock, providing the installation base for other components; the password unlocking area 2 and the fingerprint area 6 enable multiple unlocking methods; the first door handle 3 and the second door handle 4 are used for opening and closing the door; the bolt 5 controls the locking and unlocking of the door; the battery compartment 7 supplies power to all components; the speaker 8 provides voice prompts; the protective plate 9, the concave connecting seat 10, and the lens 11 form a viewing angle adjustment system, which works with the monitoring camera 12 to monitor the door's closed state; and the signal module 13 is responsible for data transmission.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a first door handle 3 is rotatably connected to the lower middle position of the front side wall of the lock body 1, and a second door handle 4 is rotatably connected to the rear side wall, directly behind the first door handle 3. The first door handle 3 and the second door handle 4 are connected by a square bar to achieve synchronous rotation. A bolt 5 is slidably connected through the side wall of the lock body 1, between the first door handle 3 and the second door handle 4. The bolt 5 is connected to the square bar by a transmission lever. When the door handle is rotated, the square bar drives the transmission lever to extend and retract the bolt 5, thereby locking and unlocking the door. A password unlocking area 2 is installed on the front side wall of the lock body 1, below the speaker 8. A fingerprint area 6 is provided on one side of the front side wall of the first door handle 3. Both the password unlocking area 2 and the fingerprint area 6 are embedded in the surface of the lock body 1 for easy user operation. A battery compartment 7 is fixedly installed in the middle of the rear side wall of the lock body 1. The battery compartment 7 is electrically connected to the nut 14, the monitoring camera 12, the signal module 13, the password unlocking area 2, the speaker 8, and the fingerprint area 6, respectively, to provide power support for the various components of the smart lock.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the monitoring camera 12 is fixedly mounted on the upper middle part of the front side wall of the lock body 1 with screws. The camera lens faces forward to capture images of the environment around the door and obtain door status information. A concave connecting seat 10 is installed on the front side wall of the lock body 1, located to one side of the monitoring camera 12, by welding or screws. A lens 11 is installed on the inner side wall of the concave connecting seat 10 by adhesive or slot fixation. The lens 11 cooperates with the monitoring camera 12 to expand the shooting angle of the monitoring camera 12 by reflecting light, enabling the camera to obtain a wider range of door status information. A threaded hole is opened on the top of the concave connecting seat 10, and a nut 14 is threaded into the threaded hole for... The lens 11 is fixed to prevent it from becoming loose. At the same time, a protective plate 9 is fixedly installed on the top of the concave connecting seat 10 with screws. The protective plate 9 covers the nut 14 and the lens 11, and serves to prevent dust and water and protect the internal structure. A signal module 13 is fixedly installed on the rear side wall of the lock body 1, located directly behind the monitoring camera 12, with screws. The signal module 13 is electrically connected to the monitoring camera 12 via a data cable. The signal module 13 has a built-in wireless communication chip, which can transmit the image data captured by the monitoring camera 12 to the user's mobile phone or smart home control system via wireless networks such as Wi-Fi, Bluetooth or 4G / 5G. The monitoring camera 12 is an Interlingda ultra-low light full-color camera.

[0028] It should be noted that when using this utility model: when the door is closed, the user can activate the door closing status monitoring function by operating the control button on the smart lock or through the associated mobile application. The lens 11 is fixed at a fixed angle, with the angle between the lens 11 and the door being 30 degrees, enabling the monitoring camera 12 to acquire omnidirectional image information of the door. The monitoring camera 12 transmits the captured image to the signal module 13, which then sends the image data to the user's mobile phone or smart home control center via a wireless network. The control center uses an image recognition algorithm to analyze the image and determine whether the door is completely closed. When the user leaves, if the door is not completely closed, the speaker 8 will issue a voice prompt, and the mobile application will also push a reminder message to inform the user of the door status and remind the user to return and close the door as soon as possible.

[0029] Users can choose between fingerprint or password unlocking. When a user places their finger in the fingerprint area 6, the fingerprint recognition module reads the fingerprint information and transmits it to the smart lock's main control chip for comparison. If the fingerprint matches successfully, the main control chip controls the transmission lever to retract the bolt 5, allowing the user to open the door by turning the first door handle 3 and the second door handle 4. If the user chooses password unlocking, entering the correct password in the password unlocking area 2 will also trigger the main control chip to retract the bolt 5, thus opening the door.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
