Description

Technical Field

[0001] This utility model belongs to the field of security monitoring technology and relates to a monitoring device for light-blocking control. Background Technology

[0002] In modern society, surveillance devices are widely used in various public areas, such as city streets, parking lots, and squares, to ensure public safety and maintain social order. However, these surveillance devices are usually installed in open-air environments and face interference from many external factors, among which lighting factors have a particularly significant impact on image quality.

[0003] Specifically, the rising and setting of the sun causes constant changes in the angle and intensity of light. In the morning and evening, sunlight may shine directly at a low angle onto the camera, while at midday, the sun may shine down from directly overhead. This change in the angle of light makes it difficult for the camera to adapt, easily leading to overexposed or blurry images. Furthermore, car headlights are a significant source of interference. At night or in low-light environments, car headlights may shine directly onto the camera, causing glare or overly bright areas in the image, severely impacting monitoring effectiveness. Other lighting sources, such as streetlights and advertising lights, can also interfere with the camera, degrading the quality of the surveillance footage.

[0004] These lighting issues not only affect the normal operation of monitoring devices, reducing the clarity and stability of the monitored images, but may also shorten the lifespan of the devices. Prolonged exposure to strong light can accelerate the aging of internal optical components in the camera assembly, such as lens aging and performance degradation of the photosensitive element, thereby increasing maintenance and replacement costs. Therefore, effectively addressing the interference of light on monitoring devices and improving image quality has become an urgent problem to be solved in the field of monitoring technology. Summary of the Invention

[0036] This utility model provides an appendix. Figures 1-6 In this embodiment of the invention, a monitoring device for adjusting light shading includes:

[0037] The housing 1 has a light-shielding groove 11 on its front side, and an annular guide groove 12 is provided inside the light-shielding groove 11;

[0038] Circuit bracket 2, which is installed inside the housing 1;

[0039] Camera component 3 is located at the front end of the circuit bracket 2. One end of the camera component 3 is fixedly connected to the circuit bracket 2, and the other end of the camera component 3 extends out of the housing 1 from the light-shielding groove 11.

[0040] Adjustable driven component 4, which is rotatably connected to the camera component 3, is provided with a baffle 6 in the direction of the light-shielding groove 11, and the baffle 6 extends out of the housing 1 through the annular guide groove 12;

[0041] The driving component 5 is disposed inside the housing 1. One end of the driving component 5 is fixedly connected to the circuit support 2, and the driving end of the driving component 5 is connected to the adjustment driven component 4 through transmission.

[0042] The housing 1 serves as the basic structure of the entire device, and its front side is designed with a light-shielding groove 11. This groove structure not only provides installation space for the camera component 3 and the adjustment driven component 4, but also provides a defined path for the movement of the baffle 6. An annular guide groove 12 is further provided inside the light-shielding groove 11. This design cleverly guides the movement direction of the baffle 6, ensuring that the baffle 6 can rotate along a preset trajectory, thereby achieving precise light blocking. The design of the annular guide groove 12 ensures that the baffle 6 remains stable during movement, avoiding deviation caused by external forces or its own movement, thus guaranteeing the reliability and consistency of the light-shielding effect.

[0043] The circuit bracket 2 is installed inside the housing 1, serving to support and fix the camera assembly 3 and the drive component 5. Its position and structural design ensure the stable installation of the camera assembly 3 and the drive component 5 within the housing 1, providing a fundamental guarantee for the normal operation of the entire device. The camera assembly 3 is installed at the front end of the circuit bracket 2, with one end fixedly connected to the circuit bracket 2 and the other end extending out of the housing 1 from the light-shielding groove 11. This layout allows the camera assembly 3 to directly face the monitoring area for image acquisition. At the same time, its fixed connection method ensures the stability of the camera assembly 3 during operation, avoiding shaking or displacement caused by external factors, thereby ensuring the clarity and stability of image acquisition.

[0044] The driven adjustment component 4 and the camera component 3 are connected by a rotational connection. This connection allows the driven adjustment component 4 to be flexibly adjusted in position as needed. The driven adjustment component 4 has a baffle 6 in the direction of the light-shielding groove 11. The baffle 6 extends out of the housing 1 through the annular guide groove 12. When the light conditions change, the driven adjustment component 4 can rotate according to the command of the driving component 5, driving the baffle 6 to move within the annular guide groove 12, thereby realizing the light-shielding control of the camera component 3. This design not only realizes dynamic light blocking, but also allows for flexible adjustment of the light-shielding angle and range according to different light conditions, improving the adaptability of the device in complex light environments.

[0045] The driving component 5 is installed inside the housing 1, with one end fixedly connected to the circuit support 2 and the driving end connected to the adjustment driven component 4 via a transmission mechanism. As the power source for the entire device, the driving component 5 can be designed as an electric motor or servo motor to provide sufficient power to drive the movement of the adjustment driven component 4. One end of the driving component 5 is fixedly connected to the circuit support 2, and the driving end is connected to the adjustment driven component 4 via a transmission mechanism. The driving component 5 receives external control signals to drive the adjustment driven component 4. This design allows the device to respond quickly to real-time light conditions and automatically adjust the position of the baffle 6 to achieve precise light blocking. The transmission connection method of the driving component 5 ensures efficient power transmission, enabling the adjustment driven component 4 to move smoothly and accurately, thereby guaranteeing the accuracy and reliability of the light-blocking control.

[0046] Through the synergistic effect of the aforementioned components, the light-blocking control monitoring device of this invention achieves dynamic light-blocking control of the camera component 3. This design not only effectively blocks direct sunlight, avoiding problems such as image overexposure and blurring caused by strong direct light, but also automatically or manually adjusts the light-blocking angle and range of the baffle 6 according to changes in the actual monitoring environment, creating a relatively stable and suitable lighting environment for the camera component 3. Furthermore, by flexibly adjusting the position of the baffle 6, the device can extend the service life of the monitoring device, reduce maintenance and replacement costs, improve the clarity and stability of the monitoring image, and enhance the flexibility and adjustability of the monitoring device, enabling it to better adapt to various public area monitoring scenarios.

[0047] The light-shielding groove 11 is in a stepped, layered shape, and each layer of the light-shielding groove 11 is provided with an annular guide groove 12.

[0048] Specifically, the tiered, stepped light-shielding grooves 11 allow the baffles 6 to more flexibly adapt to changes in light angle and intensity during movement. For example, in a city street surveillance scenario, the angle of sunlight changes throughout the day, from a low angle in the morning to a high angle at noon, and then back to a low angle in the evening. Through the tiered, stepped light-shielding grooves 11, different baffles 6 can rotate between different levels, ensuring effective blocking of direct sunlight at different times and preventing image overexposure caused by strong direct light. Furthermore, the annular guide grooves 12 within each light-shielding groove 11 further ensure the precision and stability of the baffle 6's movement. In practical applications, the baffles 6 need to be quickly adjusted according to changes in light. For example, in a traffic monitoring scenario, car headlights may suddenly shine onto the camera 32, causing image blurring. Through the design of the annular guide grooves 12, the baffles 6 can quickly adjust their position to precisely block car headlights, ensuring that the camera 32 can continuously acquire clear images.

[0049] Furthermore, the tiered, stepped light-shielding groove 11 design effectively reduces light reflection and scattering. In practical applications, light is reflected and absorbed multiple times after entering the light-shielding groove 11, thereby reducing the intensity of light directly hitting the camera component 3. For example, in a monitoring scenario in an outdoor plaza, surrounding buildings and the ground may reflect sunlight, causing light scattering. Through the tiered, stepped light-shielding groove 11 design, these reflected and scattered light rays are absorbed multiple times, reducing interference with the camera component 3 and improving image clarity and stability.

[0050] In practical implementation, when lighting conditions change, the driving component 5 will drive the driven component 4 to move according to an external control signal. The driven component 4 will move the baffle 6 within the annular guide groove 12, thereby blocking the light. Since the light-blocking groove 11 is stepped, the baffle 6 can flexibly switch between different levels to adapt to different light angles and intensities. For example, in a parking lot monitoring scenario, lights from different directions may shine on the camera 32. Through the stepped light-blocking groove 11 design, the baffle 6 can flexibly adjust its position to ensure that the camera 32 can obtain a clear image.

[0051] In summary, the light-shielding grooves 11 are designed in a stepped, tiered manner, with each layer featuring an annular guide groove 12. This design not only enhances the flexibility and adaptability of the device but also ensures the precision and stability of the baffle 6's movement, effectively reducing light reflection and scattering, and improving the imaging quality and lifespan of the camera assembly 3. This design offers significant advantages and effectiveness in practical applications, better meeting the needs of various monitoring scenarios.

[0052] The adjustment driven component 4 includes at least one driven gear 41;

[0053] The driven gear 41 is movably connected to the camera assembly 3, one end of the baffle 6 is fixedly connected to the driven gear 41, and the other end of the baffle 6 extends out of the housing 1 through the annular guide groove 12.

[0054] The driven component 4 includes at least one driven gear 41, which is movably connected to the camera component 3. Specifically, the driven gear 41 is rotatably connected to the sleeve 31 of the camera component 3, so that the rotation of the driven gear 41 can directly affect the position of the baffle 6. One end of the baffle 6 is fixedly connected to the driven gear 41. This fixed connection can be achieved by screws, rivets, or other mechanical connections to ensure that the relative position between the baffle 6 and the driven gear 41 remains constant. The other end of the baffle 6 extends out of the housing 1 through an annular guide groove 12. This design allows the baffle 6 to rotate along the trajectory of the annular guide groove 12 under the drive of the driven gear 41, thereby blocking the light.

[0055] When the drive component 5 receives an external control signal, it drives the driven gear 41 to rotate via a transmission connection. Since the baffle 6 is fixedly connected to the driven gear 41, the rotation of the driven gear 41 will cause the baffle 6 to move within the annular guide groove 12. The design of the annular guide groove 12 ensures that the movement trajectory of the baffle 6 is stable and predictable, avoiding the situation where the baffle 6 deviates or gets stuck during the movement. This design allows the baffle 6 to flexibly adjust its position and angle according to changes in light conditions, thereby realizing dynamic light-blocking control of the camera component 3.

[0056] For example, in an outdoor monitoring scenario, when the angle of sunlight changes, the drive component 5 will drive the driven gear 41 to rotate accordingly based on the feedback signal from the light sensor. The baffle 6 then moves within the annular guide groove 12, adjusting its shading angle to ensure that the camera 32 can acquire clear and accurate image information. This dynamic shading adjustment function not only improves the adaptability of the camera component 3 in complex lighting environments but also effectively avoids problems such as image overexposure and blurring caused by direct sunlight.

[0057] Furthermore, the design of the driven gear 41 provides greater flexibility and scalability to the device. Depending on actual needs, the number of driven gears 41 can be one or more, thereby achieving more complex motion control and finer light-blocking adjustment. For example, in cases where multi-angle and multi-layer light blocking is required, multiple driven gears 41, along with corresponding annular guide grooves 12 and driving components 5, can be designed. Each driven gear 41 is driven by a corresponding driving component 5, and each driven gear 41 controls a baffle 6. By coordinating the movement of these driven gears 41, all-round light blocking can be achieved.

[0058] In summary, the design of the driven component 4, through the movable connection between the driven gear 41 and the camera component 3, and the fixed connection between the baffle 6 and the driven gear 41, achieves precise control over the position of the baffle 6. This design not only allows for flexible adjustment of the shading angle and range according to changes in lighting conditions, but also ensures the stability and reliability of the baffle 6's movement, thus providing a relatively stable and suitable lighting environment for the camera component 3. This technical solution has significant advantages and effects in practical applications, and can better meet the needs of different monitoring scenarios.

[0059] The driven gear 41 is provided with an annular opening 42;

[0060] The number of driven gears 41 is two or more, and adjacent driven gears 41 are stacked. The annular opening 42 of the front driven gear 41 and the baffle 6 of the rear driven gear 41 are in clearance fit.

[0061] In this embodiment, the driven component 4 includes at least two driven gears 41, each driven gear 41 having an annular opening 42. The baffle 6 of the rear driven gear 41 can pass through the annular opening 42 to pass through the front driven gear 41, and the baffle 6 of the rear driven gear 41 can move within the annular opening 42.

[0062] When the drive unit 5 receives an external control signal, it drives any one of the driven gears 41 to rotate through the transmission connection. Due to the design of the annular opening 42 of the driven gear 41, the baffle 6 of the front driven gear 41 will not interfere with the movement of the baffle 6 of the rear driven gear 41. In this way, the rotation of each driven gear 41 will only drive its corresponding baffle 6 to move, thereby realizing independent control of a single baffle 6.

[0063] For example, in a city street surveillance scenario, light may come from multiple directions, and its intensity and angle will change over time. By independently adjusting each baffle 6, the device can flexibly adjust the position of each baffle 6, thereby achieving the blocking of light from different directions. This design not only improves the accuracy of light-blocking control but also enhances the device's adaptability to complex lighting environments.

[0064] In summary, the design of the driven gear 41 having an annular opening 42 and the baffles 6 of multiple driven gears 41 being matched in position allows multiple driven gears 41 to be closely arranged to form a compact gear set. Each driven gear 41 controls a baffle 6, thereby realizing multi-level light-shielding control. This design not only improves the accuracy of light-shielding control, but also enhances the adaptability of the device in complex lighting environments, providing the device with greater flexibility and scalability.

[0065] The camera assembly 3 includes a sleeve 31 and a camera 32;

[0066] The sleeve 31 is disposed inside the housing 1, one end of the sleeve 31 is fixedly connected to the circuit support 2, and the other end of the sleeve 31 extends out of the housing 1;

[0067] The camera 32 is installed inside the sleeve 31, and the camera 32 is electrically connected to the circuit bracket 2;

[0068] The driven gear 41 and the sleeve 31 are rotatably connected.

[0069] In this embodiment, the design of the camera assembly 3 achieves stability and reliability of the camera function through the combination of the sleeve 31 and the camera 32. The sleeve 31 is located inside the housing 1, with one end fixedly connected to the circuit bracket 2 and the other end extending out of the housing 1. The camera 32 is installed inside the sleeve 31 and electrically connected to the circuit bracket 2. The driven gear 41 is rotatably connected to the sleeve 31. This design not only ensures the stability of the camera assembly 3, but also achieves an organic combination of the light-blocking control function and the camera function.

[0070] Specifically, the sleeve 31 serves as a support structure for the camera assembly 3. One end of the sleeve is fixedly connected to the circuit bracket 2 with screws, ensuring the stability of the camera assembly 3 within the housing 1. The other end of the sleeve 31 extends out of the housing 1, providing the camera 32 with a direct channel to the monitored area. The camera 32 can be fixed inside the sleeve 31 with screws and electrically connected to the circuit board on the circuit bracket 2 via wires, ensuring the power supply and signal transmission of the camera 32.

[0071] The driven gear 41 can be rotatably connected to the sleeve 31 via a bearing, or directly to the sleeve 31. This rotatable connection allows the driven gear 41 to rotate freely on the sleeve 31 without affecting the fixed position of the camera 32. When the drive unit 5 receives an external control signal, it drives the driven gear 41 to rotate via a transmission connection. The rotation of the driven gear 41 causes the baffle 6 to move within the annular guide groove 12, thereby blocking the light. Because the driven gear 41 is rotatably connected to the sleeve 31, the movement of the baffle 6 does not affect the fixed position of the camera 32, ensuring the stability of image acquisition.

[0072] For example, in an outdoor monitoring scenario, the intensity and angle of light change over time. By rotating the driven gear 41, the baffle 6 can be flexibly adjusted to block direct sunlight, preventing image overexposure caused by strong light. Simultaneously, the camera 32 remains in a fixed position, ensuring the clarity and stability of image acquisition. This design not only improves the stability of the camera assembly 3 but also organically combines light-blocking control with camera functionality, enabling the monitoring device to optimize the camera environment under different lighting conditions, improve image quality, and extend the lifespan of the camera assembly 3.

[0073] The sleeve 31 is provided with a limiting seat 33, and the driven gear 41 is disposed in the limiting seat 33. The driven gear 41 and the sleeve 31 are rotatably connected.

[0074] The sleeve 31 serves as a support structure for the camera assembly 3, and a limiting seat 33 is provided on its exterior. The limiting seat 33 can be formed together with the sleeve 31, or it can be installed on the exterior of the sleeve 31 by welding, screw fixing, or other mechanical connection methods. The shape and size of the limiting seat 33 match the driven gear 41, ensuring the stable installation of the driven gear 41 within the limiting seat 33. The driven gear 41 can be installed in the limiting seat 33 via bearings or other rotating connections, allowing the driven gear 41 to rotate freely relative to the sleeve 31. One end of the driven gear 41 is fixedly connected to the baffle 6, which extends out of the housing 1 through the annular guide groove 12.

[0075] When the drive component 5 receives an external control signal, it drives the driven gear 41 to rotate via a transmission connection. The rotation of the driven gear 41 causes the baffle 6 to move within the annular guide groove 12, thereby blocking the light. Since the driven gear 41 is located within the limit seat 33, its rotation is more stable and will not deviate or wobble, thus ensuring the accuracy of the movement of the baffle 6. This design not only improves the stability of the camera assembly 3, but also achieves an organic combination of light-blocking control function and camera function, enabling the monitoring device to optimize the camera environment under different lighting conditions, improve image quality, and extend the service life of the camera assembly 3.

[0076] In an outdoor surveillance scenario, light intensity and angle change over time. By rotating the driven gear 41, the baffle 6 can be flexibly adjusted to block direct sunlight, preventing image overexposure caused by strong light. Simultaneously, the camera 32 remains in a fixed position, ensuring image clarity and stability. This design not only improves the stability of the camera assembly 3 but also organically combines light-blocking control with camera functionality. This allows the surveillance device to optimize the camera environment under different lighting conditions, improve image quality, and extend the lifespan of the camera assembly 3.

[0077] The baffle 6 is a quarter-circular arc-shaped sheet with a central angle of 90 degrees.

[0078] The baffle 6 is a quarter-circular arc-shaped sheet. Its outer surface has an arc-shaped outer edge and a corresponding arc-shaped inner surface, as well as two side surfaces that connect the inner and outer surfaces respectively. These four surfaces together form a regular quarter-circular arc-shaped sheet. The quarter-circular arc-shaped sheet of the baffle 6 is adapted to the light-shielding groove 11 and the annular guide groove 12 on the housing 1. When the baffle 6 extends out of the housing 1 through the annular guide groove 12, its outer and inner surfaces can slide smoothly in the guide groove. The side surface of the baffle 6 maintains a certain gap or fit with the corresponding side wall of the light-shielding groove 11 to ensure the stability and smoothness of the baffle 6 during the extension and retraction process. At the same time, it can accurately control the position change of the baffle 6 in the direction of the light-shielding groove 11, so as to achieve effective control of light.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
