[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-8 , the present invention provides a technical solution: a camera light-shielding device, including an installation box 1 and an adjusting mechanism 7. The left side of the installation box 1 is open. An L-shaped installation plate 3 is fixed on the top surface of the installation box 1. Fixed blocks 5 are fixed on the left side surface of the installation box 1 near the front and rear ends. The camera body 2 is installed on the inner bottom surface of the installation box 1. A rotating roller 6 is rotatably connected between the two fixed blocks 5. A light-shielding plate 4 is fixedly connected to the outer wall of the rotating roller 6. A limiting groove is opened on the top surface of the light-shielding plate 4. The adjusting mechanism 7 is arranged on the left bottom surface of the horizontal plate end of the installation plate 3 and is used to adjust the angle of the light-shielding plate 4.

[0032] The adjusting mechanism 7 includes a vertical plate 71 fixed on the bottom surface of the horizontal plate end of the installation plate 3 and in an L shape, a rotating column 72 rotatably connected between the horizontal plate end of the vertical plate 71 and the horizontal plate end of the installation plate 3, a cylindrical cam 73 coaxially fixed on the circumferential outer wall of the rotating column 72, a moving block 74 slidably connected to the right side surface of the vertical plate end of the vertical plate 71, a connecting rod 77 fixed on the front side surface of the moving block 74, and a limiting block 79 slidably connected to the limiting groove on the top surface of the light-shielding plate 4. A lifting rod 78 is fixedly connected to the bottom surface of the front end of the connecting rod 77. The bottom of the lifting rod 78 is hinged to the limiting block 79. A motor 711 for driving the rotating column 72 to rotate is fixedly connected to the left bottom surface of the horizontal plate end of the installation plate 3. A spiral chute is provided on the circumferential outer wall of the cylindrical cam 73, and a sliding column 75 slidably connected to the chute on the outer wall of the cylindrical cam 73 is fixed on the right side surface of the moving block 74.

[0033] During use, the camera body 2 can be shielded from light by the up-and-down flipping of the left side of the light-shielding plate 4, avoiding the influence of external sunlight on the imaging effect of the camera body 2. Moreover, through the design of the adjusting mechanism 7, the angle of the up-and-down flipping of the light-shielding plate 4 can be adjusted, so that the angle of the light-shielding plate 4 can be adjusted according to the position of the sun, thereby making the light-shielding effect of the entire light-shielding device better.

[0034] In this embodiment, the adjusting mechanism 7 further includes two meshing gears 710 located above the light-shielding plate 4 and a rotating shaft 712 coaxially connected to the output shaft of the motor 711. The output shaft of the motor 711 is vertically downward, and the two gears 710 are respectively coaxially fixed to the bottom of the rotating shaft 712 and the circumferential outer wall of the rotating column 72. By driving the rotating shaft 712 to rotate by the motor 711, the rotating column 72 can be smoothly driven to rotate through the meshing transmission of the two gears 710, and then the cylindrical cam 73 can be indirectly driven to rotate.

[0035] In addition, the position of the light-shielding plate 4 corresponds to the lens end of the camera body 2, and the size of the light-shielding plate 4 is adapted to the lens end of the camera body 2, so that the light-shielding plate 4 can smoothly perform the light-shielding work.

[0036] Furthermore, two symmetrically arranged mounting blocks 8 are fixed on the front and rear surfaces of the mounting box 1 near the right end, and a through mounting hole is provided on the left surface of the mounting block 8. The entire light-shielding device can be mounted by inserting bolts into the mounting holes.

[0037] Even further, the longitudinal cross-sectional shape of the limiting groove on the top surface of the light-shielding plate 4 is in the shape of a "work" character, and the shape of the limiting block 79 is in the shape of a "work" character adapted to the limiting groove on the top surface of the light-shielding plate 4. By sliding the limiting block 79 embedded in the limiting groove, the connection between the limiting block 79 and the limiting groove on the top surface of the light-shielding plate 4 can be made closer, thereby preventing the limiting block 79 from detaching from the light-shielding plate 4.

[0038] Specifically, a guiding groove is provided on the right surface of the vertical plate end of the vertical plate 71, and a guiding block 76 slidably connected to the guiding groove on the right surface of the vertical plate end of the vertical plate 71 is fixed on the left surface of the moving block 74. Through the arrangement of the guiding groove and the guiding block 76, the movement of the moving block 74 can be guided, and then the movement of the lifting rod 78 can be indirectly guided.

[0039] It should be noted that the adjusting mechanism 7 further includes a protection box 713 fixed to the bottom left surface of the transverse plate end of the mounting plate 3. The motor 711 is located inside the protection box 713, and the bottom of the rotating shaft 712 rotates through the bottom surface of the protection box 713 and extends to the outside. The protection box 713 can protect the motor 711, thereby extending the service life of the motor 711.

[0040] It should be noted that the transverse cross-sectional shape of the guiding groove on the right side surface of the vertical plate end of the vertical plate 71 is convex-shaped, and the shape of the guiding block 76 is convex-shaped and adapted to the shape of the guiding groove on the right side surface of the vertical plate end of the vertical plate 71. By sliding the guiding block 76 embedded in the guiding groove, the connection between the guiding block 76 and the guiding groove on the right side surface of the vertical plate end of the vertical plate 71 can be made closer, and thus the lifting rod 78 can be made more stable during the movement indirectly.

[0041] It should be emphasized that the distance between the bottom surface of the protection box 713 and the gear 710 on the same side is 6 - 12 cm, and the distance between the left side surface of the protection box 713 and the rotating column 72 is 4 - 8 cm. In this article, the distance between the bottom surface of the protection box 713 and the gear 710 on the same side is preferably 11 cm, and the distance between the left side surface of the protection box 713 and the rotating column 72 is preferably 7 cm, so that the rotation of the two gears 710 and the rotating column 72 can be unobstructed.

[0042] Finally, it should be noted that the components such as the camera body 2 and the motor 711 involved in the present utility model are all general standard components or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the adapted controllers and power supplies, are connected by wires. The specific connection means should refer to the working principle of the present utility model, and the electrical connection between the electrical components is completed in the order of their working sequence. The detailed connection means are all well-known techniques in the art.

[0043] During the specific use of this embodiment, when the light shielding of the lens end of the camera body 2 is required, the motor 711 is first started through an external PLC. The rotation of the output shaft of the motor 711 drives the coaxial rotating shaft 712 to rotate. The rotation of the rotating shaft 712 drives the coaxial fixed same-side gear 710 on the same side to rotate. The rotation of this gear 710 drives the rotation of another gear 710 meshing with it. The rotation of the other gear 710 drives the coaxial fixed rotating column 72 to rotate. The rotation of the rotating column 72 drives the coaxial fixed cylindrical cam 73 to rotate. The rotation of the cylindrical cam 73 drives the spiral chute on its outer wall to rotate. The rotation of the cylindrical cam 73 drives the sliding column 75 slidingly connected to the chute on its outer wall to move, so that the sliding column 75 moves up and down in the spiral chute on the cylindrical cam 73. The sliding column 75 moves up and down under the guiding action of the moving block 74, the guiding block 76 and the guiding groove on the right side surface of the vertical plate end of the vertical plate 71. The movement of the sliding column 75 drives the moving block 74 fixed to it to move. The movement of the moving block 74 drives the connecting rod 77 and the lifting rod 78 to move. The movement of the lifting rod 78 drives the limiting block 79 hinged to it to slide inside the limiting groove on the top surface of the light shielding plate 4. During the sliding process, the limiting block 79 also drives the left side of the light shielding plate 4 to flip up and down. When the left side of the light shielding plate 4 flips to the appropriate angular position, the motor 711 is turned off through the external PLC, and thus the adjustment of the light shielding plate 4 is completed.

[0044] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
