The coated glass has poor conductivity and shielding performance that cannot meet the requirements. In addition, due to the size limitation of the camera, the overlap surface between the window shield and the structural parts is relatively small, which is not conducive to mass production and assembly.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be an intermediate component. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0026] like Figures 1-4 As shown, a camera window that can be quickly assembled and is resistant to electromagnetic radiation interference includes: a glass sheet 1, an optical electromagnetic shielding film 2, an inner frame 4 and an outer frame 5, wherein:

[0027] The optical electromagnetic shielding film 2 is arranged on one side of the glass sheet 1, and the glass sheet 1 is arranged in the inner frame 4. The inner frame 4 can be detachably installed in the outer frame 5, and the glass sheet 1 is pressed and fixed under the cooperation of the inner frame 4 and the outer frame 5.

[0028] It should be noted that Figure 1 For example, the optical electromagnetic shielding film 2 is fixedly connected to the left side of the glass sheet 1 (it can be glued together). During installation, the glass sheet 1 is installed in the inner frame 4, and then the outer frame 5 is installed in conjunction with the inner frame 4 to achieve compression and fixation of the glass sheet 1. The above orientation is only for the convenience of description and is not limited to a specific orientation.

[0029] The optical electromagnetic shielding film 2 has high optical transmittance, ultra-low resistance, and stable shielding performance, and forms the main body of the window structure with the glass sheet 1, wherein the glass sheet 1 is ultra-white glass or quartz glass. The shielding performance of the optical electromagnetic shielding film 2 is above 44db, the transmittance can reach 86%, and the square resistance is lower than 0.56Ω / square. The transmittance of the glass sheet 1 can be greater than 93%. Therefore, the transmittance of the combination of the glass sheet 1 and the optical electromagnetic shielding film 2 can reach 80%, which meets the effect of resisting electromagnetic radiation interference in an electromagnetic environment.

[0030] In one embodiment, a waterproof rubber pad 6 is attached to the side of the glass sheet 1 away from the optical electromagnetic shielding film 2;

[0031] A conductive rubber pad 3 is attached to the glass sheet 1 on the side where the optical electromagnetic shielding film 2 is provided;

[0032] The waterproof rubber pad 6 is attached to the left side of the glass sheet 1, and the conductive rubber pad 3 is attached to the side of the glass sheet 1 where the optical electromagnetic shielding film 2 is attached (i.e., the right side). During the installation process, the waterproof rubber pad 6, the glass sheet 1 and the conductive rubber pad 3 are combined together in the inner frame 4, and then the outer frame 5 is installed in conjunction with the inner frame 4 to achieve the compression and fixation of the waterproof rubber pad 6, the glass sheet 1 and the conductive rubber pad 3. The waterproof rubber pad 6 is used to prevent water from entering the inner frame 4 or the outer frame 5, and the optical electromagnetic shielding film 2 forms a continuous shielding structure under the action of the conductive rubber pad 3, thereby improving the shielding effect.

[0033] In one embodiment, a random metal grid is provided on a side of the optical electromagnetic shielding film 2 away from the glass 1 ; the random metal grid can effectively eliminate moiré interference.

[0034] In one embodiment, the outer side of the inner frame 4 and the inner side of the outer frame 5 are respectively provided with mutually matching threads for threaded connection.

[0035] The detachable connection between the inner frame 4 and the outer frame 5 can be achieved by threading, so that the inner frame 4 and the outer frame 5 are threadedly connected to each other, thereby pressing and fixing the waterproof rubber pad 6, the glass sheet 1 and the conductive rubber pad 3, and the disassembly process is also relatively convenient. The inner frame 4 and the outer frame 5 can be directly unscrewed to achieve quick disassembly and assembly.

[0036] The outer side of the outer frame 5 is also provided with threads, so that the entire camera window can be installed on the camera through the threads.

[0037] In one embodiment, both the glass sheet 1 and the optical electromagnetic shielding film 2 are circular structures.

[0038] In one embodiment, the conductive rubber pad 3 and the waterproof rubber pad 6 are both annular structures.

[0039] In one embodiment, the inner frame 4 includes a first folded edge 41 and a first disc 42 in a circular shape, and the first folded edge 41 is fixedly connected to the first disc 42. The outer frame 5 includes a second folded edge 51 and a second disc 52 in a circular shape, and the second folded edge 51 is fixedly connected to the second disc 52. The thread on the inner frame 4 is located on the outer wall of the first folded edge 41, and the thread on the outer frame 5 is located on the inner wall of the second folded edge 51.

[0040] The first folded edge 41 and the first disc 42 are both annular structures. The inner wall of the first folded edge 41 is fixedly connected to the edge side of the first disc 42 to form an accommodating cavity. The inner wall of the second folded edge 51 is fixedly connected to the edge side of the second disc 52 to form an accommodating cavity. When installed between the inner frame 4 and the outer frame 5, the two accommodating cavities are arranged facing each other, and the accommodating cavity of the outer frame 5 half-wraps the inner frame 4. The waterproof rubber pad 6, the glass sheet 1 and the conductive rubber pad 3 are located together between the two accommodating cavities.

[0041] In one embodiment, the sum of the width of the first folded edge 41, the thickness of the first disc 42, and the thickness of the second disc 52 is less than or equal to the width of the second folded edge 51; this arrangement allows the first folded edge 41 and the second folded edge 51 to be located on both sides of the integrated structure (an integrated structure consisting of the waterproof rubber pad 6, the glass sheet 1, and the conductive rubber pad 3) for compression and fixation.

[0042] The experimental data of the shielding performance of the assembled camera window under the electromagnetic wave frequency of 30M~1.5GHz is as follows Figure 4 As shown, from Figure 4 As can be seen from the figure, the camera window can achieve a shielding effectiveness of more than 44dB for electromagnetic waves within 30M to 1.5GHz, thus achieving the purpose of resisting electromagnetic radiation interference.

[0043] This quickly assembled camera window that resists electromagnetic radiation interference achieves light transmission and electromagnetic radiation interference resistance through a glass sheet and an optical electromagnetic shielding film. Furthermore, the optical electromagnetic shielding film forms a continuous shielding structure under the action of a conductive rubber pad, thereby improving the shielding effect. The coordination between the inner frame and the outer frame enables the camera window to be quickly installed and disassembled, greatly improving work efficiency.
