Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a waterproof casing 10 in some embodiments, and fig. 2 is a schematic sectional view of a part of the waterproof casing 10 in some embodiments. The waterproof cover 10 provided by the utility model can be used for accommodating shooting equipment to form shooting devices together with the shooting equipment, wherein the shooting equipment comprises but is not limited to panoramic cameras, motion cameras and the like. The waterproof housing 10 can provide waterproof effect for the photographing apparatus, and also can receive external view finding light and refract the external view finding light to the camera of the panoramic camera in the waterproof housing 10, so that the photographing apparatus can realize a diving photographing function.

Further, in some embodiments, the waterproof housing 10 includes a case structure 11 and a light-transmitting portion 12, and a housing cavity is provided in the case structure 11, and the photographing apparatus is housed in the housing cavity. The shell structure 11 is further provided with a view finding window 112 communicated with the accommodating cavity, and when the photographing device is accommodated in the accommodating cavity, a camera of the photographing device is arranged corresponding to the view finding window 112 so as to receive external view finding light through the view finding window 112, and the rest of the photographing device is sealed by the shell structure 11. The light-transmitting portion 12 is hermetically disposed in the viewfinder window 112, and the light-transmitting portion 12 and the case structure 11 together realize a waterproof seal of the photographing apparatus. The light-transmitting portion 12 has a light-incident surface 122 and a light-emergent surface 123 disposed opposite to each other, the light-emergent surface 123 is disposed toward the viewfinder window 112, and the light-transmitting portion 12 is capable of refracting at least an incident light ray 13 having an angle greater than 90 degrees with respect to the optical axis from the light-incident surface 122 to the viewfinder window 112.

Still further, in some embodiments, the number of the view-finding windows 112 provided on the shell structure 11 is at least two, the number of the light-transmitting portions 12 is also at least two, the light-transmitting portions 12 are provided in one-to-one correspondence with the view-finding windows 112, the at least two light-transmitting portions 12 are hermetically provided in one-to-one correspondence with the view-finding windows 112, the view angles of the at least two light-transmitting portions 12 are partially overlapped, and the sum of the non-overlapped view angles of the at least two light-transmitting portions 12 is equal to 360 degrees.

Above-mentioned waterproof housing 10 when being applied to the shooting device that has shooting equipment, the cooperation of shell structure 11 and printing opacity portion 12 can effectively seal the chamber that holds that is used for holding shooting equipment, promotes the waterproof performance of shooting device for shooting device can normally shoot the operation under water, and promotes the life of shooting device. Meanwhile, the light-transmitting part 12 can deflect the incident light 13 with the included angle larger than 90 degrees with the optical axis to the framing window 112 for the shooting equipment to collect, so that the light-transmitting part 12 can also have enough view angle when shooting operation under water, and can not shoot panorama due to shielding of the shell structure 11, thereby meeting the light receiving requirement of panorama shooting. It is understood that the photographing apparatus may have at least two cameras, the cameras may be disposed in one-to-one correspondence with the light-transmitting portions 12, and the light-transmitting portions 12 may be capable of refracting external light onto the corresponding cameras. The sum of the non-overlapping view angles of the at least two light-transmitting parts 12 is equal to 360 degrees, and the overlapping part exists in the view angles of the at least two light-transmitting parts 12, so that 360-degree panoramic shooting can be realized, and the realization of splicing the images of the cameras into a panoramic image through an algorithm is easier due to the existence of the overlapping view fields. In addition, when the housing structure 11 or the support element such as the self-timer rod connected to the housing structure 11 is located within the overlapping view field range of the at least two light transmitting portions 12, the structures such as the housing structure 11 and the support element can be hidden by the algorithm, so that the structures such as the housing structure 11 and the support element are prevented from blocking the view finding light or affecting the shooting effect.

In some embodiments, the number of the light-transmitting portions 12 is two, the directions of the two light-transmitting portions 12 are opposite, and the optical axes of the two light-transmitting portions 12 are coincident with each other, so that the photographing apparatus may also include two cameras disposed opposite to each other, each of which is disposed toward the light-emitting surface 123 of a corresponding one of the light-transmitting portions 12. When two light-transmitting portions 12 are provided, the angle of view of each light-transmitting portion 12 is greater than or equal to 183 degrees, in other words, referring to fig. 2, each light-transmitting portion 12 can at least refract part of light rays having an included angle with the optical axis of greater than 91.5 degrees to the viewfinder 112 for receiving by the camera. So set up, two printing opacity portions 12 have enough big angle of field, can cooperate to realize panorama shooting, and two printing opacity portions 12 also have enough big overlapping field of view so that the algorithm better realizes the concatenation of panoramic image and the hiding of structures such as shell structure 11, supporting element simultaneously. Of course, in other embodiments, the optical axes of the two light-transmitting portions 12 may be parallel to each other and staggered from each other, so as to adapt to diversified structural layouts of the photographing device and the shell structure 11, and improve flexibility of the design of the waterproof housing 10, so long as the two light-transmitting portions 12 cooperate to achieve panoramic photographing. It is understood that the optical axis of the light transmitting portion 12 may be disposed to overlap with the optical axis of the corresponding camera.

It will be appreciated that when there are two light transmitting portions 12, there may be two cameras, and a plurality of cameras may be used alone or together. When the two cameras are used simultaneously, the two cameras with the visual angles larger than 180 degrees are arranged back to back, images with the relative visual angles are shot, and then the shot images with the visual angles of 180 degrees are synthesized and spliced through an algorithm to obtain panoramic images, namely images with the visual angles of 360 degrees. The shooting equipment can shoot or record video, so that the spliced panoramic image can be a static picture or a dynamic video.

In some embodiments, the light-transmitting portion 12 is capable of refracting at least one incident light ray 13 into an emergent light ray 14, and an angle between the emergent light ray 14 and the incident light ray 13 is smaller than the first preset angle. The first preset included angle can be set according to actual precision requirements. In some embodiments, the first predetermined included angle is less than or equal to 5 degrees. Thus, the emergent light 14 formed by refracting the light by the light transmitting part 12 can be emitted to the shooting equipment along the direction basically parallel to the incident light 13, which is beneficial to inhibiting the generation of image distortion and improving the imaging quality of the shooting equipment. In some embodiments, taking the light-transmitting portion 12 as an aspheric lens as an example, the angle between the outgoing light 14 and the incoming light 13 is smaller than the first preset angle, and the curvature of the lens can be adjusted to meet the refraction requirement. Further, in some embodiments, the first preset included angle is smaller than or equal to 2 degrees, so that imaging quality of the photographing device can be further improved. In some embodiments, the first preset included angle is smaller than or equal to 1 degree, so that imaging quality of the photographing device can be further improved. In some embodiments, the outgoing light ray is substantially parallel to the incoming light ray, i.e. the first preset angle may be 0 degrees.

In some embodiments, in a direction radially outward along the optical axis, for example, in a direction along the optical axis directed by the camera toward the light transmitting portion 12, the effective light entrance aperture of the light entrance surface 122 is higher than the outer surface of the shell structure 11, so that light having an included angle greater than 90 degrees with the optical axis can be better received by the light transmitting portion 12 and is not easily blocked by the shell structure 11, thereby improving the angle of view of the waterproof housing 10. In some embodiments, the effective light entrance aperture of the light entrance surface 122 may be made higher than the outer surface of the shell structure 11 by increasing the distance between the light entrance surface 122 and the outer surface of the shell structure 11. For example, in some embodiments, the light-transmitting portion 12 is provided with a raised portion 121 connected to the shell structure 11, and the raised portion 121 may be integrally formed with the main body structure of the light-transmitting portion 12, or the shell structure 11 may be provided with a raised portion 121 connected to the light-transmitting portion 12, so as to increase the distance between the light-incident surface 122 and the outer surface of the shell structure 11. When the raised portion 121 is provided on the shell structure 11, the raised portion 121 includes, but is not limited to, a boss or pad that is connected to an end of the light transmissive portion 12.

In some embodiments, in the direction radially outward along the optical axis, the effective light entrance aperture of the light entrance surface 122 is higher than the effective light exit aperture of the light exit surface 123, so that the light transmitting portion 12 can refract the light at a high position to a low position, so that the camera of the photographing device located at the low position can better receive the light, and the view finding requirement of panoramic photographing is met. In some embodiments, due to the arrangement of the raised portion 121, the height difference between the incident point of the incident light ray 13 and the outer surface of the shell structure 11 is larger than the height difference between the emergent point of the emergent light ray 14 and the outer surface of the shell structure 11 in the optical axis direction, so that the photographing device can receive the light refracted by the light transmitting portion 12 without protruding or excessively protruding from the outer surface of the shell structure 11, which is beneficial to miniaturization of the waterproof housing 10 and compatibility of the waterproof housing 10 with most panoramic photographing devices.

In some embodiments, the shell structure 11 is located outside the field of view of the light transmissive portion 12, or the shell structure 11 is partially located outside the field of view of the light transmissive portion 12, and another portion is located within the overlapping field of view of at least two light transmissive portions 12. The part of the shell structure 11 outside the view field range of the light transmission part 12 can not shield the light transmission part 12 from collecting view finding light, the light transmission part 12 can not collect images of the shell structure 11, and the part of the shell structure 11 in the overlapped view field range of at least two light transmission parts 12 can be hidden through an algorithm, so that the final panoramic image does not comprise the part of the shell structure 11, and the shell structure 11 is prevented from influencing the shooting effect of shooting equipment.

In some embodiments, the housing structure 11 further includes a connection portion 113 connected to the main body portion of the housing structure 11, and the connection portion 113 is used to connect a support member such as a selfie stick, so that a user can hold the photographing device by the support member. In some embodiments, when the connection 113 is connected to the support element, the support element is located within the overlapping field of view of the at least two light-transmitting portions 12, or a portion of the support element is located outside the field of view of the light-transmitting portions 12, and another portion is located within the overlapping field of view of the at least two light-transmitting portions 12. Therefore, the image of the portion of the supporting element outside the field of view of the light transmitting portions 12 is not collected by the light transmitting portions 12, and the image of the portion of the supporting element within the overlapping field of view of the at least two light transmitting portions 12 can be hidden by the algorithm, so that the panoramic image obtained by the photographing apparatus does not include the portion of the supporting element, and the supporting element is prevented from affecting the photographing effect of the photographing apparatus.

In some embodiments, at least one of the light incident surface 122 and the light emergent surface 123 of the light transmitting portion 12 is aspheric, so that flexibility of the surface design of the light transmitting portion 12 can be improved, and it is beneficial to improve the imaging quality by adjusting the surface shape, the curvature and the aspheric coefficients of the light transmitting portion 12, and improving the adverse phenomena such as unclear image, distortion of vision, narrow field of view and the like while realizing the refraction requirement of light. Further, the light incident surface and the light emergent surface are both aspheric.

Further, as shown in fig. 1, 2 and 3, the light incident surface 122 is convex and aspheric, the light emergent surface 123 is concave and aspheric, and the thickness of the light transmitting portion 12 at the effective light incident aperture is greater than the center thickness. So set up, the shape of printing opacity portion 12 can obtain reasonable design, be favorable to promoting the deflection ability of printing opacity portion 12 to the wide-angle light, for example to the deflection ability of the light that is greater than 90 degrees with the contained angle between the optical axis for printing opacity portion 12 can be with at least with the incident light 13 deflection that the optical axis contained angle is greater than 90 degrees to viewfinder 112 supplies shooting equipment to gather, so that printing opacity portion 12 also can possess sufficient angle of view when shooting the operation under water, can not shoot panorama because of the shielding of shell structure 11, thereby can satisfy panorama shooting's receipts light demand. Further, in some embodiments, the ratio of the thickness of the light-transmitting portion 12 at the effective light-incident aperture to the center thickness is greater than 1.5, and the edge portion of the light-transmitting portion 12 has a sufficient thickness to deflect the light, so that a sufficient viewing angle can be provided.

When the above conditional expression is satisfied, the radii of curvature of the light incident surface 122 and the light emergent surface 123 of the light transmitting portion 12 can be reasonably configured, so that the light incident surface 122 and the light emergent surface 123 can form a good fit, the light incident surface 122 can effectively deflect light with a large angle to the light emergent surface 123, the light emergent surface 123 can reasonably configure light collected by the light incident surface 122 in cooperation with the light incident surface 122, the field angle of the light transmitting portion 12 is improved, meanwhile, aberration such as distortion is suppressed, and the imaging quality of the photographing device is improved.

When the above conditional expression is satisfied, the effective apertures of the light incident surface 122 and the light emergent surface 123 can be reasonably configured, so that the light transmitting portion 12 has a sufficient light receiving range, which is favorable for improving the viewing angle of the light transmitting portion 12, and satisfying the requirement of panoramic shooting.
