Description

Technical Field

[0001] The present application relates to underwater photography equipment, and more specifically to a sealed underwater camera. Background Art

[0002] Underwater cameras usually have a light, and can only capture what is happening in the water when the light is dim by shining the light into the water. Some underwater cameras have several lenses on the front of the main body, such as lenses corresponding to the lens, lenses corresponding to the light, etc., and these lenses need to be connected to the shell with a waterproof structure. Some underwater cameras also have sensors, such as photosensors, etc., and lenses and waterproof structures also need to be set up corresponding to the sensors. For this reason, there will be multiple lenses and multiple corresponding waterproof structures in the underwater camera structure, which is relatively complex in structure and assembly, resulting in high production costs, which needs to be improved.

[0003] The above technical contents belong to the technical knowledge scope of the inventor and do not necessarily constitute prior art. Utility Model Content

[0012] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0013] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0014] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0015] The embodiment of the present application is a sealed underwater camera, and its specific structure is as follows: Figure 1-Figure 3 shown.

[0016] like Figure 1 and 2As shown, the underwater camera includes a front cover 20, a lens module 30, a photosensitive sensor 40 and a cylindrical shell 10. Among them, the front cover 20 and the shell 10 are both made of stainless steel or aviation aluminum, which can improve the pressure resistance and anti-corrosion ability of the underwater camera. The front cover 20 is fixed to the front end of the shell 10, and the front cover 20 is fixedly connected to the shell 10 by a plurality of screws, and an elastic sealing gasket 11 is sandwiched between the front cover 20 and the shell 10. The sealing gasket 11 is subjected to the front and rear pressure of the front cover 20 and the shell 10, so that the front cover 20 and the shell 10 can be waterproof. The sealing gasket 11 can be made of rubber material.

[0017] like Figure 2 and Figure 3 As shown, the front cover 20 is provided with a middle hole 21, and the lens module 30 is inserted into the middle hole 21. The lens module 30 is arranged on a bracket 31, and the four arms 32 of the bracket 31 are fixedly connected to the front cover 20 by screws. In front of the lens module 30 is a lens 60, which is pressed tightly in the middle hole 21 by a pressing ring 50, and a sealing ring 61 is provided on both the front and rear sides of the lens 60. In some examples, such as Figure 2 and Figure 3 As shown, a retaining ring 211 is provided at the front end of the middle hole 21, a sealing ring 61 is sandwiched between the lens 60 and the retaining ring 211, and another sealing ring 61 is sandwiched between the pressing ring 50 and the lens 60. The pressing ring 50 enters the middle hole 21 from the rear end of the middle hole 21 and presses the lens 60 therein, so the two sealing rings 61 are pressed at the same time, thereby achieving waterproofing on both sides of the lens 60.

[0018] In some embodiments, Figure 2 As shown, the outer surface of the pressing ring 50 is provided with an external thread 51, and the middle hole 21 is provided with an internal thread 212. The pressing ring 50 and the middle hole 21 are threadedly connected. The pressing ring 50 rotates into the middle hole 21, and the rear end of the pressing ring 50 is provided with 4 evenly distributed grooves 52. When the pressing ring 50 needs to be twisted, a tool can be inserted into the groove 52 and then a counterclockwise or clockwise twisting force can be applied to the pressing ring 50 through the tool.

[0019] In other embodiments, the pressing ring 50 and the middle hole 21 are fixedly connected in other ways. Figure 3 As shown, at least one positioning groove 213 is provided around the rear end of the middle hole 21, and the pressure ring 50 is provided with a positioning plate 53 correspondingly. When the pressure ring 50 is inserted into the middle hole 21, the positioning plate 53 is placed in the positioning groove 213 and the two are fixedly connected by screws 531. Specifically, there are 4 positioning grooves 213 and they are evenly distributed around the central axis of the middle hole 21, and the positioning plates 53 correspond to the positioning grooves 213 one by one and the shape of the positioning plates 53 is consistent with the shape of the positioning grooves 213. Each positioning plate 53 is fixedly connected to the positioning groove 213 by two screws 531.

[0020] like Figure 2 As shown, the front end face of the front cover 20 is provided with an inwardly concave annular groove 22, and an annular circuit board 70 with a lamp bead 71 is provided in the annular groove 22, and the annular circuit board 70 is fixed in the annular groove 22 by screws. The annular groove 22 is filled with an annular transparent first glue-filled sealing layer 81. The front end face 811 of the first glue-filled sealing layer 81 needs to be polished smooth to allow light to be evenly scattered outward. The lamp bead 71 can be an LED lamp bead, an infrared lamp bead or a laser diode lamp bead, etc.

[0021] like Figure 2 As shown, the front cover 20 is also provided with a perforation 23, and the photosensitive sensor 40 penetrates into the perforation 23, and the front end of the perforation 23 is filled with a transparent second glue-filling sealing layer 82. The front end surface 821 of the second glue-filling sealing layer 82 needs to be polished smooth so that the photosensitive sensor 40 can receive more uniform external light.

[0022] In some embodiments, Figure 2 As shown, the distance between the center axis of the through hole 23 and the center axis of the middle hole 21 is equal to the distance from the lamp bead 71 to the center axis of the middle hole 21, so that the distribution of the lamp bead 71 and the photosensitive sensor 40 of the front cover 20 can be more coordinated.

[0023] In some embodiments, Figure 2 As shown, the through hole 23 is separated from the annular groove 22 by its own inner wall, so that there is a physical isolation between the lamp bead 71 and the photosensitive sensor 40, and the light emitted by the lamp bead 71 is not easy to enter the photosensitive sensor 40, and the photosensitive sensor 40 will not misjudge the light emitted by the lamp bead 71 as ambient light, thereby avoiding the situation where the lamp bead 71 continues to alternate between on and off due to the misjudgment of the photosensitive sensor 40.

[0024] The lamp beads 71 ​​and the annular circuit board 70 used for lighting in the present application are sealed by a first glue-potting sealing layer 81, and the photosensitive sensor 40 is sealed by a second glue-potting sealing layer 82, while the lens 60 of the lens module 30 retains the original sealing ring sealing form, reducing the number of lenses, and adopts a glue-potting method to seal the lighting and sensing positions. The lens 60 is retained in front of the lens module 30 to ensure the imaging effect. On the basis of not affecting the imaging, the waterproof structure is simplified, the assembly is also simplified, and the manufacturing cost is also reduced.
