Referring to fig. 5 and 6, fig. 5 shows a top view of the photographing system of the present embodiment, fig. 6 shows a partial cross-sectional view of the photographing system of fig. 5, and the protective case 200 includes a case 210, a lens 220, and a light shielding member 230. The housing 210 is provided with a viewing window 211, the viewing window 211 is communicated with an inner space of the housing 210, the inner space accommodates the photographing apparatus 110, and the lens 120 of the photographing apparatus 110 extends into the viewing window 211. The lens 220 is disposed on the housing 210 and corresponding to the viewing window 211, thereby forming a viewing window of the protective case 200. At least a portion of the light shielding member 230 is disposed in the viewing window 211, and a through hole 231 is formed in the light shielding member 230, wherein the through hole 231 is used for the lens 120 of the photographing device 110 to extend into or pass through, so that the light shielding member 230 is located between the wall of the viewing window 211 and the lens 120.

By disposing the light shielding member 230 between the hole wall of the window hole 211 and the lens 120, that is, disposing the light shielding member 230 in a gap formed between the window of the protective case 200 and the window of the photographing apparatus 110, the light shielding member 230 can shield at least part of the light passing through the gap, thereby reducing or eliminating the light reflected into the lens 120 after being irradiated to the lens 220, further reducing or eliminating the influence of the underwater stray light on the photographing image quality of the photographing apparatus 110 during the deep water photographing, and improving the imaging quality of the deep water photographing of the photographing apparatus 110.

In this embodiment, the lens 120 of the photographing apparatus 110 passes through the through hole 231 of the light shielding member 230 and is disposed near the lens 220 of the protective case 200, so that the wide-angle photographing effect is better. It will be appreciated that in other embodiments, the lens 120 of the photographing apparatus 110 may extend only into and not through the through hole 231 of the light shielding member 230. In order to obtain a better photographing effect, the through hole 231 of the light blocking member 230 may be disposed close to the lens 220 of the protective case 200 such that the lens 120 extending into the through hole 231 is also close to the lens 220 of the protective case 200.

Referring to fig. 3 and 4, further, the housing 210 includes a first housing 212, a second housing 213, and a sealing rubber ring 214, the first housing 212 and the second housing 213 are covered to form an inner space of the housing 210, and the sealing rubber ring 214 is disposed at a connection between the first housing 212 and the second housing 213 to seal the connection. The sealing rubber ring 214 is pressed between the side surfaces of the connection part of the first housing 212 and the second housing 213, and the sealing rubber ring 214 can be extended to positive pressure, and simultaneously pressed between the front surfaces of the connection part of the first housing 212 and the second housing 213, so that the sealing effect is better. The viewing window 211 is formed on the first housing 212, the first housing 212 is disposed at least corresponding to the front side of the photographing apparatus 110, the second housing 213 is disposed mainly corresponding to the rear side of the photographing apparatus 110, and the side walls formed by closing the first housing 212 and the second housing 213 are disposed corresponding to the peripheral sides of the photographing apparatus 110.

In order to facilitate the opening and closing of the housing 210, one side wall of the first housing 212 is rotatably connected to one side wall of the second housing 213 through a rotation shaft 215, and the other side wall of the first housing 212 is snap-connected to the other side wall of the second housing 213 through a latch structure (not shown). When the photographing apparatus 110 is placed, the latch structure is operated to the unlocking position, and the housing 210 is opened and the photographing apparatus 110 is placed; the latch structure is then operated to the latched position to seal the closure housing 210.

In order to reduce or avoid the eccentricity between the lens 120 of the loaded photographing apparatus 110 and the window of the protective case 200, the inner side of the through hole 231 of the light blocking member 230 is adapted to the outer side of the lens 120, and the lens 120 is positioned without positioning the windows of the lens 120 and the protective case 200 through other structures of the case 210. In other words, the diameter of the lens 120 is equal to or substantially equal to the aperture of the through hole 231 of the light shielding member 230, and it is needless to say that it is possible that the aperture of the through hole 231 of the light shielding member 230 is slightly larger (slightly larger) than the diameter of the lens 120 due to the existence of manufacturing tolerances, without substantially affecting positioning alignment. Of course, the aperture of the through hole 231 of the light shielding member 230 is ideally equal to the diameter of the lens 120 to be completely matched, and the positioning alignment effect is better. When the photographing apparatus 110 is set, the lens 120 of the photographing apparatus 110 is inserted into the through hole 231 of the light shielding member 230, and then the entire photographing apparatus 110 is placed in the first housing 212, and then the second housing 213 is covered, at this time, the through hole 231 of the light shielding member 230 automatically positions the lens 120 of the photographing apparatus 110, and other positioning structures in the housing 210 position the main body of the photographing apparatus 110 in other directions, and finally the center of the lens 120 of the photographing apparatus 110 set in the protective housing 200 is aligned with the center of the window of the protective housing 200.

Further, a plurality of ribs 216 are disposed on the inner side of the peripheral wall of the first housing 212, and the ribs 216 are disposed at intervals corresponding to the peripheral side of the photographing apparatus 110, so that the peripheral side of the photographing apparatus 110 is clamped in the peripheral wall of the first housing 212.

The through hole 231 is opened at the first end 232 and is communicated with the accommodating space 234. The lens 120 is accommodated in the accommodating space 234 formed by gradually expanding the through hole 231, and the light shielding member 230 can be arranged around at least part of the lens 120 in the axial direction of the lens 120 so as to shield part or all of light rays entering the lens 120 from the side, thereby further improving the light shielding effect of the light shielding member 230 and better reducing the influence of underwater stray light on the imaging quality. It is understood that in other embodiments, the light shielding member 230 may be a planar sheet structure, without having the receiving space 234 formed in a divergent manner, and the through hole 231 is formed in the center thereof in a ring shape.

Further, since the end surface of the second end 233 is disposed near to or in contact with the inner surface of the lens 220, and the lens 120 is disposed at a distance from the lens 220 of the protective housing 200, the end surface of the second end 233 can extend out of the mirror surface of the lens 120, so that the lens 120 in the accommodating space 234 is completely surrounded by the light shielding member 230, and light cannot enter the lens 120 from the side, so that the light shielding effect of the light shielding member 230 is better, and the influence of underwater stray light on the shooting image quality of the shooting device 110 is greatly reduced or avoided.

Further, the inner side surface of the light shielding member 230 is provided with a light absorbing structure 235, and the light absorbing structure 235 can absorb the light entering the accommodating space 234 of the light shielding member 230, so as to prevent the light from being reflected between the inner side surface of the light shielding member 230 and the lens 220 and entering the lens 120. In this embodiment, the light absorbing structure 235 includes a plurality of steps arranged in succession, each of which is annular, so that the light absorbing structure 235 visually forms a CD ring. It should be noted that, in other embodiments, the light absorbing structure 235 may be formed by roughening the inner surface of the light shielding member 230, or by coating or adhering a light absorbing material layer.
