Description

Technical Field

[0001] This utility model belongs to the technical field of video surveillance equipment, and in particular relates to a video surveillance equipment with an infrared supplementary light module. Background Technology

[0002] There are many types of cameras, but their basic working principle is to convert optical image signals into electrical signals for storage or transmission. The core component of a camera is the camera module. When the camera module photographs an object, the light reflected from the object is collected by the lens of the camera module and focused onto the light-receiving surface of the camera module (such as the target surface of a camera tube). The camera module then converts the light into an electrical signal. Infrared cameras are mainly used in dark environments with no visible light or very low light. They use an infrared emitting device to actively project infrared light onto an object, and the infrared light is reflected by the object and enters the lens to form an image.

[0003] Chinese patent application CN219046524U discloses an infrared supplementary lighting camera module. This module includes a housing, an infrared camera, and an infrared supplementary light. The housing has separate, independent first and second mounting cavities. The infrared camera is mounted in the first mounting cavity, and the infrared supplementary light is mounted in the second mounting cavity, avoiding direct interference between the infrared supplementary light and the infrared camera. This infrared supplementary lighting camera module, by using an infrared supplementary light, emits infrared light from the opening of the lens barrel, illuminating the object and diffusing it into the infrared camera to provide infrared supplementary lighting. This compensates for the lack of clarity in infrared camera images due to low light conditions, solving the problem of existing infrared camera modules being unable to capture clear images for effective monitoring in dim lighting.

[0004] Because the outer casing of this patent is a one-piece structure, the lens needs to be disassembled and reassembled when the internal parts are inspected, which may damage the lens and thus shorten the service life of the video surveillance equipment.

[0005] To address these issues, we provide a video surveillance device with an infrared fill light module. Utility Model Content

[0006] The purpose of this invention is to provide a video surveillance device with an infrared supplementary light module, which solves the problem of cumbersome disassembly and assembly of existing video surveillance devices through the cooperation of the outer shell component and the fixing component.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a camera monitoring device with an infrared supplementary light module, comprising a housing assembly, an inner cavity of which is provided with a fixing component, the housing assembly including a front shell and a rear shell, each of the four corners of the rear shell having a receiving groove, the bottom of the inner cavity of the receiving groove having a threaded hole, both sides of the inner cavity of the receiving groove having a limit groove, the inner cavity of the limit groove having an installation groove, each of the four corners of the back of the front shell having a connecting pipe fixedly connected, each of the four corners of the front shell having an installation hole communicating with the connecting pipe, the fixing component including a spring fixedly connected to the inner cavity of the installation groove, the other end of the spring being fixedly connected to a pin, the inner cavity of the pin being slidably connected to a limit rod, the other end of the limit rod being fixedly connected to the inner wall of the installation groove, both sides of the surface of the connecting pipe being fixedly connected to limit blocks, the surface of the limit blocks having pin holes, the inner cavity of the installation hole being provided with a bolt, the bolt being threadedly connected to the threaded hole through the inner cavity of the connecting pipe.

[0009] The present invention is further configured such that a fitting groove is provided on the opposite side of the front shell and the rear shell, and a sealing ring is fitted inside the fitting groove. The sealing ring inside the fitting groove can enhance the sealing performance after the two are connected, effectively prevent external dust, moisture and other substances from entering the equipment, protect the internal electronic components and optical components, and improve the environmental adaptability and service life of the equipment.

[0010] The present invention is further configured such that the surface of the pin hole is rounded, which reduces the friction and collision between the pin and the edge of the pin hole, allowing the pin to slide into and out of the pin hole more smoothly.

[0011] The present invention is further configured such that a sliding hole is provided in the inner cavity of the pin, and one end of the limiting rod extends into the inner cavity of the sliding hole. The cooperation between the sliding hole and the limiting rod can precisely limit the movement trajectory of the pin, prevent the pin from deviating under the action of the spring, and ensure that the pin can be accurately engaged in the pin hole.

[0012] The present invention is further configured such that one end of the pin and the pin hole are both designed in a hemispherical shape. During the installation process, the hemispherical structure can play a guiding role, making it easier for the pin and the pin hole to be aligned and fitted, reducing installation resistance and improving the assembly efficiency of the front shell and the rear shell.

[0013] The present invention is further configured such that one end of the bolt located in the inner cavity of the threaded hole is provided with an external thread, and the inner cavity of the threaded hole is provided with an internal thread, so that the bolt can stably connect the front shell and the rear shell through the threaded engagement.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model designs the outer shell assembly as a split structure of front and rear shells, and uses a fixing component to achieve quick assembly and disassembly. This solves the problem that the lens needs to be removed during maintenance of traditional integrated shells, which can easily cause damage. When maintaining internal parts, it is only necessary to unscrew the bolts and separate the front and rear shells without touching the lens or other precision parts. This effectively protects the optical components, extends the service life of the equipment, simplifies the maintenance process, and improves maintenance efficiency.

[0016] 2. This utility model adopts a cooperative structure of spring, pin and limit block. During the installation process, the pin is pre-fixed by engaging with the pin hole, and then tightened by bolts. The double fixing method enhances the stability of the shell connection. At the same time, the setting of the sealing ring improves the sealing performance of the equipment, which can effectively prevent dust, water vapor and other substances from entering the interior, ensuring the stable operation of the infrared supplementary light module and camera components, and is suitable for a variety of complex environments.

[0026] Please see Figure 1-5 This utility model relates to a video surveillance device with an infrared supplementary lighting module, comprising a housing assembly 1, a fixing assembly 2 disposed within the inner cavity of the housing assembly 1, the housing assembly 1 including a front shell 11 and a rear shell 12, each of the four corners of the surface of the rear shell 12 having a receiving groove 13, the bottom of the inner cavity of the receiving groove 13 having a threaded hole 14, both sides of the inner cavity of the receiving groove 13 having a limiting groove 15, the inner cavity of the limiting groove 15 having an installation groove 16, and each of the four corners of the back of the front shell 11 having a connecting pipe 17 fixedly connected, and each of the four corners of the surface of the front shell 11 having an installation hole. 18. The mounting hole 18 is connected to the connecting pipe 17. The fixing component 2 includes a spring 21 fixedly connected to the inner cavity of the mounting groove 16. The other end of the spring 21 is fixedly connected to a pin 22. The inner cavity of the pin 22 is slidably connected to a limit rod 23. The other end of the limit rod 23 is fixedly connected to the inner wall of the mounting groove 16. Limit blocks 24 are fixedly connected to both sides of the surface of the connecting pipe 17. The surface of the limit block 24 is provided with a pin hole 25. The inner cavity of the mounting hole 18 is provided with a bolt 26. The bolt 26 is threadedly connected to the threaded hole 14 through the inner cavity of the connecting pipe 17.

[0027] Specifically: This equipment achieves convenient maintenance and stable operation through a split outer shell assembly 1. By passing the bolts 26 sequentially through the mounting holes 18 and the inner cavity of the connecting pipe 17 and then threading them into the threaded holes 14, a stable connection between the front shell 11 and the rear shell 12 is achieved.

[0028] Example 2

[0029] Please see Figure 1-5 Based on Embodiment 1, the front shell 11 and the rear shell 12 are provided with fitting grooves 19 on opposite sides. The inner cavity of the fitting groove 19 is fitted with a sealing ring 110. The surface of the pin hole 25 is rounded. The inner cavity of the pin rod 22 is provided with a sliding hole. One end of the limiting rod 23 extends into the inner cavity of the sliding hole. One end of the pin rod 22 and the pin hole 25 are both designed as hemispherical. The bolt 26 is provided with an external thread at one end of the threaded hole 14. The inner cavity of the threaded hole 14 is provided with an internal thread.

[0030] Specifically: A sealing ring 110 is fitted inside the fitting groove 19, which can enhance the sealing performance after the two are connected, effectively preventing external dust, moisture and other substances from entering the equipment, protecting the internal electronic components and optical components, and improving the environmental adaptability and service life of the equipment. The rounded corners of the pin hole 25 can reduce the friction and collision between the pin 22 and the edge of the pin hole 25, allowing the pin 22 to slide into and out of the pin hole 25 more smoothly. The cooperation between the sliding hole and the limiting rod 23 can accurately limit the movement trajectory of the pin 22, prevent the pin 22 from deviating under the action of the spring 21, and ensure that the pin 22 can accurately engage with the pin hole 25. During the installation process, the hemispherical structure can play a guiding role, making it easier for the pin 22 and the pin hole 25 to be aligned and cooperate, reducing installation resistance, improving the assembly efficiency of the front shell 11 and the rear shell 12, and the bolt 26 can firmly connect the front shell 11 and the rear shell 12 through the threaded engagement.

[0031] The working principle of this utility model is as follows: The connecting tube 17 of the front shell 11 is aligned with the receiving groove 13 of the rear shell 12 and inserted. During the process, the limiting block 24 squeezes the pin 22, which compresses the spring 21. When the pin hole 25 on the limiting block 24 corresponds to the position of the pin 22, the spring 21 resets and pushes the pin 22 into the pin hole 25, thus achieving the pre-fixation of the front shell 11 and the rear shell 12. Then, the bolt 26 is passed through the mounting hole 18 and the connecting tube 17 of the front shell 11 and threadedly connected to the threaded hole 14 of the rear shell 12 to complete the final tightening. At the same time, the sealing ring 110 ensures the sealing of the shell. When maintenance is required, the bolt 26 is unscrewed, and the pin 22 is disengaged from the pin hole 25 under the action of external force, so that the front shell 11 and the rear shell 12 can be separated, which facilitates the maintenance of the internal infrared supplementary light module and camera components. Through the double fixing of the fixing component 2 and the cooperation of the sealing structure, the equipment can be quickly disassembled and assembled, and can work stably in various environments.
