Description

Technical Field

[0001] This utility model relates to a cat's eye lens, specifically a visual cat's eye lens with a wide field of view. Background Technology

[0002] like Figure 1 As shown, Figure 1 This is the structure of a video peephole camera in existing technology. The video peephole camera is installed inside the door, and its camera's field of view is as follows: Figure 1 Area A, Figure 1 Area B is outside the camera range of the existing visible cat's eye head.

[0003] Figure 1 Area B, located near the ground outside the door, is a blind spot for surveillance cameras, posing a security risk and failing to meet users' needs for comprehensive monitoring of the area outside their doors. With the widespread use of online shopping, numerous packages are frequently left at residents' doors, and this near-ground blind spot happens to be a primary storage area for these packages. Because existing peephole cameras cannot cover this area, users cannot monitor the status of their packages in real time: when a courier arrives, it's impossible to confirm whether the package has been placed correctly; when no one is home, if a package is mistakenly taken or maliciously stolen, users cannot detect it in time, nor can they trace the responsible party through the footage recorded by the peephole.

[0004] At night, the existing peephole cameras have limited night vision capabilities. Coupled with the lack of ground-level surveillance, even if suspicious individuals linger at the door or rummage through packages, users cannot obtain effective visual evidence through the peephole. This leads to frequent disputes over lost or damaged packages, causing economic losses and difficulties in protecting users' rights. This surveillance blind spot not only affects users' comprehensive control over their surroundings but also exposes significant functional deficiencies in high-frequency delivery interaction scenarios, urgently requiring improvement.

[0005] Therefore, it is necessary to improve the existing installation structure of the peephole head. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a peephole camera with a wide field of view, which can expand the field of view, cover the vertical ground area, and eliminate blind spots in monitoring.

[0007] To solve the above-mentioned technical problems, the present invention achieves this through the following solution: The present invention provides a visual cat's eye head with a wide field of view, including a housing and a camera module. The housing has an inclined mounting hole for mounting the camera module. The inclined angle of the inclined mounting hole enables the field of view of the camera module to cover the vertical ground area.

[0008] Furthermore, after the camera module is installed into the tilted mounting hole, the central axis of its lens is tilted downwards and the angle between it and the vertical plane is 62 degrees.

[0009] Furthermore, the first angle formed by the lowest point of the camera module's field of view and the lens is perpendicular to the ground, and the second angle formed by the highest point of the camera module and the lens is inclined upwards, with the angle between the second angle and the horizontal direction being 34 degrees.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] Example 1: The specific structure of this utility model is as follows:

[0036] Please refer to the appendix. Figure 1-6 The present invention provides a viewing cat's eye camera with a wide field of view, comprising a housing and a camera module 2. The housing has an inclined mounting hole 11 for mounting the camera module 2. The inclined angle of the inclined mounting hole 11 enables the field of view of the camera module 2 to cover the vertical ground area.

[0037] After the camera module 2 is installed into the inclined mounting hole 11, the central axis of its lens is tilted downward and the angle between it and the vertical plane is 62 degrees.

[0038] The first angle formed by the lowest point of the field of view of the camera module 2 and the lens is perpendicular to the ground, and the second angle formed by the highest point of the camera module 2 and the lens is inclined upward and the angle formed by the second angle and the horizontal direction is 34 degrees. That is, the field of view of the camera module 2 of this utility model is 124 degrees.

[0039] This invention can also match the structural tilt angle according to different camera angles to achieve approximately 90° imaging of the ground, maximizing the capture of the actual scene at the doorstep without blind spots.

[0040] The housing includes a front shell 1 and a rear shell 9 that covers the back opening of the front shell 1, and the inclined mounting hole 11 is provided in the front shell 1;

[0041] The front surface of the front shell 1 has three consecutive surfaces, with the middle surface being set as an inclined surface;

[0042] The outer opening of the inclined mounting hole 11 is located on an inclined surface;

[0043] The upper surface of the front view of the front housing 1 has a photodiode mounting hole;

[0044] The lower surface of the front view of the front shell 1 has multiple fill light holes, button holes and microphone holes.

[0045] The visual cat-eye head also includes:

[0046] A PCBA module 6 is fixed to the inner cavity of the front shell 1. The PCBA module 6 is provided with a PIR sensor, a photodiode, an infrared lamp, a microphone, and two connectors. One of the two connectors is connected to the camera module 2, and the other connector is connected to the host cable via a long ribbon cable 4. The photodiode is located in the photodiode mounting hole. There are multiple infrared lamps, and the multiple infrared lamps are set one-to-one with the multiple fill light holes. The microphone is directly opposite the microphone hole.

[0047] Doorbell button 5 is located in the button hole and abuts against the button of the PCBA module 6. Doorbell button 5 is used by visitors to press the doorbell.

[0048] Specifically, the PIR sensor detects changes in the scene; when someone approaches, the PIR sensor sends a power-on signal to the main unit. The photodiode's function is to sense the light intensity of the scene through the camera lens upon power-on and send a day or night command to the main unit. The infrared light provides supplementary illumination for the camera in darkness, achieving better night vision.

[0049] The PCBA module 6 is also provided with a speaker 8, and the rear cover 9 is provided with a speaker hole, with the speaker 8 facing the speaker hole.

[0050] The camera module 2 is fixed by the camera bracket 3. The camera bracket 3 is used to fix the camera, keeping it at a scientifically reasonable angle to achieve optimal (90° to the ground) image capture. The camera module 2 includes a sensor, a lens, and an FPC circuit. This utility model can perform tasks such as taking pictures and recording videos according to the product software design workflow and transmit the data to the host computer. Example

[0051] The following is the installation structure of the visual cat's eye head of this utility model:

[0052] 1. Place the dough upside down on the work surface;

[0053] 2. Insert the doorbell button;

[0054] 3. Insert the camera;

[0055] 4. Secure the camera to the front cover of the peephole using a bracket and tighten the screws;

[0056] 5. Insert the PCBA module and tighten the screws;

[0057] 6. Connect the camera module ribbon cable and the long ribbon cable for communication with the host to the PCBA module in sequence;

[0058] 7. Connect the speaker terminals on the PCBA module, and the speaker body is snapped into the speaker compartment in the rear shell;

[0059] 8. The long cabling for communication with the host computer passes through the slot in the middle of the bottom casing;

[0060] 9. Cover with the bottom cover, tighten the screws, test, etc. The cat's eye head assembly is now complete.

[0061] Industry background of this utility model's visual peephole camera: Since peephole products are installed inside the peephole on the door panel, the installation conditions determine the camera's viewing angle. Therefore, peephole cameras have always been designed to look straight ahead or at a slight angle, without any product that can see 90° downwards towards the doorway. This product represents a significant breakthrough in this regard. By drastically changing the product's structure and appearance, combined with the camera's wide-angle angle, the peephole camera can see 90° vertically towards the doorway.

[0062] In real-life situations, this video peephole camera performs exceptionally well in monitoring packages at the door. With the prevalence of online shopping, numerous packages are left at the door, leading to frequent losses and damages. This new video peephole camera effectively addresses this problem. Its 90° ground-facing imaging angle completely covers the area around the doorway, clearly capturing whether packages are placed on the ground or against a wall. When a courier arrives, the PIR sensor quickly detects their approach and triggers the camera module to record the entire process of package placement, including the quantity, appearance, and the courier's actions. Even when the user is not home, they can view the footage in real-time through a connected host device to clearly understand whether the package has been delivered and its placement status.

[0063] At night, when the photodiode senses low light, it instructs the infrared lights to activate, ensuring the camera captures clear images even in darkness. This allows users to accurately monitor their packages at the door, even at night. If a stranger attempts to touch, move, or take a package, the PIR sensor immediately detects the unusual activity. The camera will then continuously record and save the video, and simultaneously send an alert to the user via the main unit. The user can then take timely action, such as remotely speaking through the speaker to stop the theft, effectively preventing package theft.

[0064] In addition, users can review video recordings to confirm the time the package was left at the door and whether it has been touched by others, providing strong evidence for potential delivery disputes. For valuable packages, users can monitor them in real time. Even after the courier leaves, if they are temporarily unable to return home, they can keep track of the package's safety through the peephole, greatly improving the reliability and security of package supervision at the door and bringing great convenience to users.

[0065] In summary, by setting an inclined mounting hole, this utility model enables the camera module's field of view to cover the vertical ground area, eliminating blind spots in existing technologies and improving home security.

[0066] The camera module of this utility model has a reasonable angle setting. The angle between the lens central axis and the vertical plane is 62 degrees, and the angle between the highest point of the field of view and the horizontal direction is 34 degrees. While covering the ground area, it can also monitor the area above, achieving a wide and comprehensive field of view.

[0067] The housing structure of this utility model is ingeniously designed. The front surface of the front shell has three sequentially connected surfaces, with the middle one being an inclined surface for mounting the camera module. The upper and lower surfaces integrate mounting holes for various functional components, making the overall structure compact and highly integrated.

[0068] This utility model uses a camera bracket to fix the camera module, which ensures stable and reliable installation and facilitates disassembly and maintenance.

[0069] This utility model integrates components such as a photodiode, infrared lamp, microphone, doorbell button, and speaker, offering a wide range of functions to meet various user needs.

[0070] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
