Description

Technical Field

[0001] The utility model relates to the technical field of intelligent locks, in particular to a safety monitoring device for an intelligent lock. Background Technique

[0002] An intelligent lock is a lock that uses modern technological means to achieve the unlocking function through electronic technology, biometric technology, network communication technology, etc. Compared with traditional mechanical locks, intelligent locks provide more convenience and security. Intelligent locks are widely used in places such as homes, offices, and hotels, improving security and convenience. With the development of technology, the functions of intelligent locks are also constantly increasing and improving.

[0003] For example, an intelligent lock with a safety monitoring function disclosed in Chinese Patent Publication No. (CN211397015U) includes an intelligent lock. A groove is opened on the front of the intelligent lock and directly above the door handle of the intelligent lock. A password key panel is fixedly connected directly above the center of the groove. A fingerprint collector is fixedly connected below the password key panel in the groove. A cover plate is arranged on the front of the password key panel in the groove. A sliding groove is correspondingly opened at the position of the cover plate at the top of the groove. Springs are fixedly connected to the front and back of the center of the cover plate at the top of the cover plate. An electromagnet is fixedly connected directly below the cover plate at the bottom of the groove. By setting a single-chip microcomputer, a micro camera, and a wireless transmission module, the problem that the current intelligent lock only has the function of intelligent unlocking and no monitoring function, and it cannot monitor the situation outside the door, resulting in low security, is solved.

[0004] However, in the prior art exemplified by the above-mentioned disclosed patent, there is still a problem that the safety monitoring range of the intelligent lock is relatively limited. The installation position of the intelligent lock on the door body is roughly in the middle of the door body. And if a monitoring structure is set on the intelligent lock as in the prior art, its camera can only perform horizontal monitoring, which will cause monitoring dead angles, and thus the upper body and facial information of the unlocking person cannot be monitored, thereby affecting monitoring security. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a safety monitoring device for an intelligent lock, which has the advantages of a wide safety monitoring range, etc., and solves the problem that the safety monitoring range of the intelligent lock is relatively limited in the prior art.

[0006] To achieve the above object, the utility model provides the following technical solution: A safety monitoring device for an intelligent lock, including a lock body. A monitoring mechanism for multi-range monitoring is arranged on the front of the lock body, and a protection mechanism for protecting the monitoring mechanism from impact is arranged on the inner wall of the monitoring mechanism;

[0007] The monitoring mechanism includes an installation groove opened on the front of the lock body. A mounting plate is fixed between the inner walls on the left and right sides of the installation groove. A first micro camera is fixed on the front of the mounting plate. Rotating sleeves are fixed on the inner walls on the left and right sides of the installation groove and above the mounting plate. Damping gaskets are fixed on the inner walls of the two rotating sleeves. A rotating shaft is rotatably connected to the inner walls of the two damping gaskets. A connecting plate is fixed on the outer side of the rotating shaft. A second micro camera is fixed on the front of the connecting plate.

[0008] Furthermore, a controller is fixed on the back wall of the inner cavity of the installation groove, and the controller is electrically connected to a wireless transmission module through a wire. A storage battery is provided inside the lock body.

[0009] Furthermore, the length of the damping gasket is equal to the depth of the inner cavity of the rotating sleeve.

[0010] Furthermore, supplementary light lamps are fixed on the left and right sides of both the first micro camera and the second micro camera.

[0011] Furthermore, the protection mechanism includes a support frame plate fixed on the inner wall of the installation groove. A plurality of pressure sensors are fixed on the front of the support frame plate. A combined frame is fixed on the front of the plurality of pressure sensors. An explosion-proof plate is clamped between the inner walls on the four sides of the combined frame.

[0012] Furthermore, the plurality of pressure sensors are arranged in a uniformly distributed annular shape on the front of the support frame plate. The pressure sensors are electrically connected to an alarm through a wire.

[0013] Furthermore, the explosion-proof plate is a high-transparency explosion-proof glass plate. Card slots are opened on the inner walls on the four sides of the combined frame, and the four sides of the outer surface of the explosion-proof plate are respectively clamped in the inner walls of the four card slots.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] 1. For the safety monitoring device of this intelligent lock, the monitoring mechanism can capture a wider field of view by setting two micro cameras on the front of the lock body, reducing the monitoring blind spots, thereby improving the coverage of safety monitoring. The first micro camera is responsible for capturing the front image, while the second micro camera can flexibly monitor the monitoring blind area of the first camera through the rotation adjustment of the rotating shaft, realizing seamless splicing of images. This not only enhances the monitoring ability of the surrounding environment of the door lock but also provides more detailed safety information for users, significantly improving the safety performance of the intelligent lock and providing a safer and more reliable monitoring structure for users.

[0016] 2. The safety monitoring device of the intelligent lock. The protection mechanism provides a transparent monitoring view by setting an explosion-proof plate in front of the camera and also acts as a solid defense line to protect the camera from direct impact or damage from the outside. When there is an attempt to damage or block the camera, the pressure sensor can quickly sense the pressure change on the explosion-proof plate and transmit the signal to the controller. Once the pressure exceeds the preset safety threshold, the alarm will be triggered to give an alarm and send a warning message to the user through the wireless transmission module to remind the user to take corresponding safety measures. In addition, the design of the protection mechanism also takes into account maintenance and durability, so that the intelligent lock can maintain its monitoring function even after being subjected to multiple impacts, thus providing continuous safety protection for the user in the long term.

Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 , a safety monitoring device of an intelligent lock in this embodiment, includes a lock body 1. A monitoring mechanism 2 for multi-range monitoring is provided on the front surface of the lock body 1, and a protection mechanism 3 for protecting the monitoring mechanism 2 from impact is provided on the inner wall of the monitoring mechanism 2.

[0023] In this embodiment, a controller is fixed to the back wall of the inner cavity of the installation groove 21, and the controller is electrically connected to a wireless transmission module through a wire. A storage battery is provided inside the lock body 1. The controller receives the image signals from the two cameras and performs necessary image processing, such as compression, format conversion, etc. Then, the controller stitches the images of the two cameras to form a broader monitoring field of view. The processed images are sent to a preset receiving device, such as the user's smart phone or a remote monitoring center, during the entire monitoring process.

[0024] Please refer to Figure 2 , for multi-range monitoring, the monitoring mechanism 2 in this embodiment includes an installation groove 21 opened on the front surface of the lock body 1. An installation plate 22 is fixed between the left and right inner walls of the installation groove 21. A first micro camera 23 is fixed to the front surface of the installation plate 22. Rotating sleeves 24 are fixed to the left and right inner walls of the installation groove 21 and above the installation plate 22. Damping gaskets 25 are fixed to the inner walls of the two rotating sleeves 24. A rotating shaft 26 is rotatably connected to the inner walls of the two damping gaskets 25. During the entire monitoring process, the storage battery inside the lock body 1 provides continuous power support for the monitoring mechanism 2. The damping gasket 25 increases the rotational friction of the rotating shaft 26. After the user adjusts the monitoring angle, the damping gasket 25 can prevent the rotating shaft 26 from rotating freely, ensuring the stability of the monitoring angle. A connecting plate 27 is fixed to the outer side of the rotating shaft 26. A second micro camera 28 is fixed to the front surface of the connecting plate 27. When installing the intelligent lock, the user can adjust the monitoring angle of the second micro camera 28 by rotating the rotating shaft 26 so that it can cover the monitoring dead angle of the first micro camera 23. The two micro cameras start to capture images within their respective monitoring ranges.

[0025] In this embodiment, the length of the damping gasket 25 is equal to the depth of the inner cavity of the rotating sleeve 24. Supplementary light lamps 29 are fixed to the left and right sides of both the first micro camera 23 and the second micro camera 28. If the ambient light is insufficient, the supplementary light lamps 29 will automatically turn on to ensure that the cameras can capture clear images.

[0026] Please refer to Figure 3 , for impact protection of the monitoring mechanism 2, the protection mechanism 3 in this embodiment includes a support frame plate 31 fixed to the inner wall of the installation groove 21. A plurality of pressure sensors 32 are fixed to the front surface of the support frame plate 31. A combined frame 33 is fixed to the front surface of the plurality of pressure sensors 32. The combined frame 33 in front of the explosion-proof plate 34 will sense the pressure and transmit this pressure to the pressure sensors 32. The pressure sensors 32 are installed on the combined frame 33. When an external force acts on the explosion-proof plate 34, the pressure sensors 32 can sense this pressure change. The explosion-proof plate 34 is clamped between the four inner walls of the combined frame 33.

[0027] In this embodiment, several pressure sensors 32 are evenly distributed in a ring on the front surface of the support frame plate 31. The pressure sensors 32 are electrically connected to an alarm through wires. The explosion-proof plate 34 is a high-transparency explosion-proof glass plate. The explosion-proof plate 34 is made of high-transparency explosion-proof glass. This material can not only ensure that the camera captures clear external images, but also provide physical protection for the camera to prevent external forces from directly damaging the camera. Slots 35 are provided on the inner walls of the four sides of the combined frame 33, and the four sides of the outer surface of the explosion-proof plate 34 are respectively clamped in the inner walls of the four slots 35.

[0028] It should be noted that when the explosion-proof plate 34 is subjected to external forces, the pressure sensors 32 can sense this pressure change. Once the pressure change is detected, the pressure sensors 32 transmit signals to the controller through wires. After receiving the signals, the controller will determine whether the pressure exceeds the preset safety threshold. If the pressure exceeds the safety threshold, the controller will trigger the alarm to sound an alarm. The alarm not only sounds an alarm on the spot, but may also send warning messages to the user through a wireless transmission module, such as sending them to the user's smartphone or other monitoring centers.

[0029] The working principle of the above embodiment is as follows:

[0030] (1) When installing the intelligent lock, the user can adjust the monitoring angle of the second micro camera 28 by rotating the rotating shaft 26 so that it can cover the monitoring dead angle of the first micro camera 23. The two micro cameras start to capture images within their respective monitoring ranges. If the ambient light is insufficient, the supplementary light 29 will automatically turn on to ensure that the cameras can capture clear images. The controller receives the image signals from the two cameras and performs necessary image processing, such as compression, format conversion, etc. Then, the controller stitches the images of the two cameras to form a broader monitoring field of view. The processed images are sent to a preset receiving device, such as the user's smartphone or a remote monitoring center, through a wireless transmission module. During the entire monitoring process, the storage battery inside the lock body 1 provides continuous power support for the monitoring mechanism 2. The damping gasket 25 increases the rotational friction of the rotating shaft 26. After the user adjusts the monitoring angle, the damping gasket 25 can prevent the rotating shaft 26 from rotating freely and ensure the stability of the monitoring angle.

[0031] (2) The explosion-proof plate 34 is made of a highly transparent explosion-proof glass plate. This material can not only ensure that the camera captures clear external images, but also provide physical protection for the camera to prevent external forces from directly damaging the camera. When someone attempts to damage or block the camera, the combined frame 33 in front of the explosion-proof plate 34 will sense the pressure and transmit this pressure to the pressure sensor 32. The pressure sensor 32 is installed on the combined frame 33. When the explosion-proof plate 34 is subjected to external force, the pressure sensor 32 can sense this pressure change. Once the pressure change is detected, the pressure sensor 32 transmits the signal to the controller through a wire. After receiving the signal, the controller will determine whether the pressure exceeds the preset safety threshold. If the pressure exceeds the safety threshold, the controller will trigger the alarm to issue an alarm. The alarm not only issues an alarm on-site, but may also send a warning message to the user through a wireless transmission module, such as sending it to the user's smartphone or other monitoring centers.

[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
