Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] See Figure 1-4 Example 1: A camera protective cover includes a protective cover 1, a base 2 and a protective shell 3. The base 2 is annular, the protective cover 1 is fixed to the bottom of the base 2, the top of the base 2 is fixedly connected to the protective shell 3, and a sealing ring 24 is installed between the base 2 and the protective shell 3.

[0030] Example 2: In this example, the base 2 includes an inner ring 23, a middle ring 22 and an outer ring 21. There is an annular mounting groove 25 between the middle ring 22 and the outer ring 21. A rib 28 is provided in the mounting groove 25. The bottom of the protective shell 3 is provided with a slot to avoid the rib.

[0031] To improve the high-temperature resistance and impact resistance of the protective cover, in one embodiment of this utility model, the protective cover is made of polycarbonate, and ultraviolet stabilizers and plasticizers are added during the synthesis of polycarbonate. The modified polycarbonate has excellent ultraviolet resistance and further impact resistance; the transmittance in the 400-700nm band reaches more than 90%, the image quality meets the ISO 12233 test standard, and the top and four sides meet the IK10 test requirements.

[0032] See Figure 7-8 In one embodiment of this utility model, a mounting groove 4 for installing a sealing ring is provided at the top of the middle ring. The sealing ring is installed in the mounting groove, with its shape and position consistent with the middle ring groove. It is slightly reduced by 0.1mm and has a thickness of 1-3mm, which is adapted to the size of other components. It is used for sealing the interior between the protective shell and the base, effectively preventing water, dust, etc. from flowing into the camera.

[0033] See Figure 5-6In one embodiment of this utility model, a connector 32 is fixed to the bottom of the protective shell 3. The connector 32 is annular and has several connecting parts. Each connecting part includes a positioning tube 321, a pair of grooves for placing the substrate circuit and a fixing block 324. The pair of grooves for placing the substrate circuit includes a first groove 322 and a second groove 323. At least one connecting part has a first limiting block 325 on its side to prevent the overall tooling from shifting in the X-axis direction, and at most one connecting part has a second limiting block 326 at its bottom to prevent the overall tooling from shifting in the Y-axis direction. This second limiting block also serves a positioning function and is only protruding on one side to facilitate orientation identification during assembly.

[0034] See Figure 2-6 To facilitate the installation of the protective shell 3 and the base 2, based on the previous embodiment, an annular mounting plane 210 is provided between the inner ring 23 and the middle ring 22. A positioning pin 26 is provided in the mounting plane 210, and a positioning tube 321 that cooperates with the positioning pin 26 is provided at the bottom of the protective shell 3. Through the cooperation between the positioning tube 321 and the positioning pin 26, the positioning is quick and accurate during installation, improving the installation efficiency.

[0035] See Figure 2 , Figure 3 and Figure 5 In one embodiment of this utility model, the protective shell is provided with a screw hole 31, and the connection between the base and the protective shell is achieved by fixing with a screw 27 (note that the screw 27 in the figure is not tightened at this time, but is only shown as the corresponding position of the screw in the figure. The screw is tightened when the protective shell and the base are assembled). The two are detachable, which provides convenience for subsequent replacement of parts or disassembly and maintenance.

[0036] See Figure 1 and Figure 3 In one embodiment of this utility model, the protective cover 1 is hemispherical, hollow inside with an opening, and the opening end of the protective cover 1 is provided with an annular flange edge 11, which is welded to the inner side of the inner ring 23.

[0037] In one embodiment of this utility model, the protective shell 3 is made of aluminum alloy or stainless steel, and the thickness of the protective shell is 2.5-3mm.

[0038] In one embodiment of this utility model, the protective cover 1 has an optically hardened layer on its surface. The optically hardened layer is composed of modified polysiloxane, with polysiloxane as the main component. Polar substances and UV stabilizers are added during the synthesis process. Compared with conventional polysiloxane, the outdoor service life is greatly extended. The service life of a typical polysiloxane hardened layer is 3 years, while that of a modified layer can reach 5 years. The film layer is smooth and has excellent anti-pollution ability, ensuring light transmission while improving wear resistance.

[0039] In one embodiment of this utility model, the thickness of the protective cover is 2-4mm.

[0040] In one embodiment of this utility model, the thickness of the sealing ring is 1-3 mm.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
