Description

Technical Field

[0001] This utility model relates to the field of camera technology, specifically to a compact waterproof camera. Background Technology

[0002] As a key device for video image acquisition, cameras are widely used in many fields such as security monitoring, industrial inspection, and outdoor sports recording. With the increasing diversification and complexity of application scenarios, the requirements for camera performance are becoming more and more stringent, especially in terms of waterproof performance. Many existing camera products are unable to fully meet the actual use needs.

[0003] In certain specialized working environments, such as marine aquaculture monitoring, cameras need to be exposed to high humidity and corrosive salty air for extended periods. The waterproof structures of ordinary cameras are easily corroded and damaged in such conditions, leading to a significant decrease in waterproof performance. Furthermore, in outdoor security monitoring scenarios with frequent heavy rain, existing waterproof cameras are susceptible to water seepage through tiny gaps when subjected to prolonged heavy rainfall, causing lens blurring and image quality degradation. Additionally, in low-temperature, high-humidity environments, the waterproof structures of traditional cameras may expand and contract due to temperature changes, creating gaps in previously sealed areas and failing to effectively prevent moisture ingress, thus affecting the camera's normal operation. Currently, although some cameras on the market claim to be waterproof, most suffer from complex structures, large size, and poor waterproofing. Some cameras employ complex, multi-layered nested structures to achieve waterproofing, which not only increases manufacturing costs and installation difficulty but also makes it difficult to reduce the camera's size, hindering its use in space-constrained environments. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned cameras, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a compact waterproof camera that solves the problems of poor waterproof performance, complex structure, and large size of existing cameras in complex environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A compact waterproof camera includes a front shell and a rear shell. The rear shell is threaded onto one side of the front shell. A first waterproof sealing structure is provided at the connection between the front shell and the rear shell.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a compact waterproof camera.

[0024] This utility model provides, for example Figure 1-3The compact waterproof camera shown includes a front shell 1 and a rear shell 2. The rear shell 2 is threaded onto one side of the front shell 1. A first waterproof sealing structure is provided at the connection between the front shell 1 and the rear shell 2. The first waterproof sealing structure includes an annular groove 3 and a waterproof rubber ring 4 formed on the edge of the front shell 1. The waterproof rubber ring 4 is embedded in the annular groove 3. A protrusion 5 is provided on the front shell 1 at a position corresponding to the annular groove 3. The protrusion 5 matches the annular groove 3. A lens mounting part 6 is provided at the front end of the front shell 1. A second waterproof sealing structure is provided on the front end face of the lens mounting part 6. The second waterproof sealing structure includes a transparent waterproof lens 7 provided on the front end face of the lens mounting part 6. The edge of the transparent waterproof lens 7 is aligned with the lens mounting part 6. The inner wall of part 6 is filled with waterproof sealant 8. A cable 9 is installed on the rear shell 2. A waterproof rubber sleeve 10 is provided on the outer wall of the cable 9. The waterproof rubber sleeve 10 is fixedly connected to the rear shell 2. A circuit board 11 and an image sensor 12 are fixedly installed inside the rear shell 2. A thermally conductive silicone 13 is fixedly provided on the outer wall of the circuit board 11. The thermally conductive silicone 13 is fixedly connected to the inner wall of the rear shell 2. In terms of waterproof sealing, the front shell 1 and the rear shell 2 are tightly fastened by a threaded connection. The first waterproof sealing structure at the connection plays a core role: the waterproof rubber ring 4 in the annular groove 3 on the edge of the front shell 1 is squeezed when the protrusion 5 at the corresponding position is embedded in the annular groove 3, which fully fills the gap between the two and forms the first waterproof barrier. To prevent moisture from seeping in from the housing connection, in the second waterproof sealing structure of the lens mounting part 6, a transparent waterproof lens 7 covers the front end face, and the waterproof sealant 8 filled between its edge and the inner wall of the lens mounting part 6 forms a sealing layer after curing, preventing moisture from entering from the lens area. The waterproof rubber sleeve 10 on the outside of the cable 9 is fixedly connected to the rear shell 2, tightly wrapping the cable 9 to prevent moisture from entering along the contact gap between the cable 9 and the rear shell 2, forming a third layer of waterproof protection. At the same time, the desiccant pack 15 on the inner wall of the rear shell 2 absorbs any trace amounts of moisture that may be present inside, further consolidating the waterproof effect. In terms of heat dissipation and stable operation, the thermally conductive silicone 13 on the outer wall of the circuit board 11 and the inner wall of the rear shell 2... The direct wall-mounted connection efficiently conducts the heat generated by the camera components, such as the circuit board 11 and image sensor 12, to the rear shell 2. Several heat dissipation fins 14 on the outer surface of the rear shell 2 increase the contact area with the outside, accelerate heat dissipation, and prevent the components from being affected by overheating. In addition, the tight fit between the front shell 1 and the rear shell 2 and the integrated molding design of the lens mounting part 6 ensure the compactness of the overall structure and reduce the possibility of gaps. The high-strength engineering plastic rear shell 2, the transparent waterproof lens 7 made of sapphire glass, and the waterproof rubber sleeve 10 made of silicone rubber improve the corrosion resistance and durability of the camera in harsh environments, ensuring its long-term stable operation.

[0025] For better heat dissipation, such as Figure 1 As shown, the outer surface of the rear shell 2 is provided with several heat dissipation ribs 14.

[0026] For better flexibility, such as Figure 1 As shown, the waterproof rubber sleeve 10 is made of silicone rubber.

[0027] For better use of the lenses, such as Figure 1 As shown, the transparent waterproof lens 7 is made of sapphire glass.

[0028] Finally, to make the interior drier, such as Figure 2 As shown, the rear shell 2 is made of high-strength engineering plastic, and a desiccant pack 15 is provided on the inner wall of the rear shell 2.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
