[0002] The current panoramic shooting equipment uses two viewfinders set back to back, each lens has a visual angle of more than 180 degrees, and the images taken by the two lenses are synthesized and spliced ​​through an algorithm to obtain a panoramic image.

[0003] When using a panoramic shooting device in water, the viewfinder lens needs to be additionally waterproofed, such as using a waterproof cover to wrap the viewfinder lens. Due to the structure of the waterproof cover itself, the panoramic shooting device cannot synthesize a panoramic image in one shot like in water, but needs to rotate a certain angle and shoot again to synthesize a panoramic image.

[0078] like Figure 1A panoramic shooting device 900 shown in the figure includes a bottom surface 901 and a top surface 902 arranged opposite to each other, and a peripheral surface 903 connected between the bottom surface 901 and the top surface 902. The panoramic shooting device 900 is provided with a plurality of viewfinder lenses 904. In some embodiments, a viewfinder lens 904 is provided on the top surface 902, and another viewfinder lens (not shown) is also provided on the bottom surface 901 opposite to each other. The plurality of viewfinder lenses 904 can be used individually or together at the same time. When two viewfinder lenses 904 are used at the same time, two viewfinder lenses 904 with a visual angle of view greater than 180 degrees are arranged back to back to shoot images of relative angles, and then the images with a 180-degree angle of view are synthesized and spliced ​​by an algorithm to obtain a panoramic image, that is, an image with a 360-degree angle of view. The panoramic shooting device 900 can take pictures and record videos, so the panoramic image obtained by splicing can be either a static picture or a dynamic video. At least one control key 905 is disposed on the top surface 902 and the peripheral surface 903 , such as a start shooting key, a function switching key, a power button, a custom function key, and other control keys 905 .

[0079] When the panoramic shooting device 900 is shooting underwater, it needs to be waterproofed, for example, using a waterproof shell to cover the viewfinder lens 904, and the structural setting of the waterproof shell itself will inevitably block the light of some angles from entering the viewfinder lens 904 of the panoramic shooting device 900, so the panoramic shooting device 900 needs to be rotated at a certain angle and the part that is not framed is photographed again to synthesize a panoramic image, which is not convenient for underwater use. Based on this, the present application provides a waterproof cover 100 that provides protection for the panoramic shooting device 900 when the panoramic shooting device 900 is shooting underwater.

[0080] See also Figure 2-Figure 5As shown, in some embodiments, the waterproof housing 100 includes a housing structure 1 and at least two light-transmitting parts 2. A sealed cavity 19 for accommodating a panoramic shooting device 900 is provided in the housing structure 1. The panoramic shooting device 900 is placed in the sealed cavity 19, so that the housing structure 1 plays a waterproof role for the panoramic shooting device 900. The housing structure 1 is also provided with at least two viewfinder windows 17 connected to the sealed cavity 19. The viewfinder windows are used for the panoramic shooting device to take pictures. The housing structure is also provided with a connecting part 141 for connecting a supporting device. The panoramic shooting device can be supported by the supporting device to facilitate underwater shooting. The light-transmitting parts 2 correspond to the number of viewfinder lenses 904 of the panoramic shooting device, and the installation positions are also set accordingly; illustratively, there are at least two light-transmitting parts 2, and at least two light-transmitting parts 2 are set along the axial direction of the housing structure 1, and are sealed and set at the viewfinder windows 17 one by one. It can be understood that the light-transmitting parts 2 are used to allow external light to enter the sealed cavity 19, and the shooting device can take pictures through the light-transmitting parts 2. At the same time, the fields of view of the two light-transmitting parts 2 overlap, so that image stitching is achieved by using the overlapping area; and the sum of the field angles of the non-overlapping fields of view is 360 degrees, that is, the viewing angle of the two light-transmitting parts 2 after framing is 360 degrees, and there is no need to rotate the panoramic shooting device 900 to a certain angle to shoot again, and a panoramic 360-degree framing shooting can be achieved. The light-transmitting part 2 can also be designed with a specific structure according to the refractive index of the different material media used, so that the panoramic shooting device 900 can adapt to the shooting environment in the water and meet the needs of underwater panoramic shooting. When the panoramic shooting device has three or more lenses, the number of light-transmitting parts 2 can be adaptively increased, and the principle is similar, which will not be repeated here.

[0081] Reference Figure 2 , the shell structure is provided with a connection portion 141 for connecting the supporting device, and the fields of view of the at least two light-transmitting portions 2 toward the connection portion 141 at least partially overlap. In practical applications, the supporting device may be a selfie stick, and during shooting, the light-transmitting portion 2 will capture the selfie stick in the photo, causing a glitch. In this embodiment, the fields of view of the at least two light-transmitting portions 2 toward the connection portion 141 at least partially overlap, so that the overlapping images captured by the panoramic shooting device can be used to eliminate the selfie stick to avoid glitch.

[0082] Reference Figure 2 In some embodiments, the number of the light-transmitting portions 2 is two, the two light-transmitting portions 2 face opposite directions and have parallel optical axes, and the field of view of each light-transmitting portion 2 is greater than 183 degrees. In this way, the overlapping area of ​​the images taken by the two lenses of the panoramic shooting device is greater than 1.5 degrees, so that the two images can be matched through the feature points of the overlapping part to achieve image stitching and improve the stitching accuracy.

[0083] See also Figure 6As shown, the light-transmitting portion 2 refracts at least one incident light L1 into an outgoing light L3. Through refraction, the light is deflected so that the light with an angle greater than 90 degrees with the optical axis can be incident on the panoramic shooting device, thereby achieving panoramic shooting. Specifically, if the angle between the outgoing light L3 and the incident light L1 is less than the first preset angle, the outgoing light L3 enters the panoramic shooting device 900 in a direction substantially parallel to the incident light L1, thereby avoiding image distortion. In some embodiments, taking the lens of the light-transmitting portion 2 as an aspherical lens as an example, the angle between the outgoing light L3 and the incident light L1 can be less than the first preset angle by adjusting the curvature of the lens so that it meets the refraction requirement. Among them, in the process of light passing through the light-transmitting portion 2 and entering the lens of the panoramic shooting device 900, the light is incident on the light-transmitting portion 2 as the incident light L1, and the light emitted after the incident light L1 is refracted by the light-transmitting portion 2 is the outgoing light L3, and the incident surface can receive the incident light L1 and effectively refract it to the panoramic shooting device 900. In some embodiments, the first preset angle is less than or equal to 2 degrees.

[0084] Along the radial outward direction of the optical axis of the light-transmitting portion 2 itself, the incident point of the incident light ray L1 is higher than the exit point of the exit light ray L3, and the maximum effective aperture of the incident surface of the light-transmitting portion 2 is higher than the maximum effective aperture of the exit surface, thereby refracting the light at a high place to a low place, so that the panoramic shooting equipment 900 located at a low place can obtain light and meet the panoramic framing needs.

[0085] Reference Figure 6 In some embodiments, the height difference between the incident point of the incident light L1 and the shell surface of the shell structure 1 is greater than the height difference between the exit point of the exit light L3 and the shell surface of the shell structure 1, so that the panoramic shooting device 900 does not need to protrude or excessively protrude from the shell surface of the shell structure 1 to receive the first light, which is conducive to the miniaturization of the waterproof cover 100. In addition, it is also conducive to compatibility with most panoramic shooting devices 900. In practical applications, the light-transmitting portion 2 can be a spherical lens or an aspherical lens, and the above requirements can be achieved by adjusting the curvature of the spherical lens or the aspherical lens, which will not be repeated here.

[0086] Reference Figure 6 and Fig.16 In some embodiments, the incident point of the incident light L1 is higher than the shell surface of the shell structure 1, so that the field of view angle of the light-transmitting portion 2 can be made larger, so that the overlapping area of ​​the images captured by the two viewfinders 904 of the panoramic shooting device is larger, which is beneficial to improving the accuracy of image stitching.

[0087] In some embodiments, the above structure can be achieved by setting a spacing between the outer lens surface of the light-transmitting portion 2 and the shell surface of the shell structure 1, and increasing the distance between the incident surface of the light-transmitting portion 2 and the shell surface of the shell structure 1. For example, a support member (such as a boss or a gasket, etc.) is set at the edge of the outer lens surface of the light-transmitting portion 2; for another example, a support member (such as a boss or a gasket, etc.) is set at the contact surface between the shell structure 1 and the light-transmitting portion 2. The specific implementation method is not limited here, as long as the spacing between the outer lens surface of the light-transmitting portion 2 and the shell surface of the shell structure 1 is satisfied.

[0088] In some embodiments, reference Figure 6 and Figure 7 As shown, the light-transmitting portion 2 includes a first lens 21, and the first lens 21 is provided with a raised portion 211 connected to the shell structure 1, or the shell structure is provided with a raised portion connected to the first lens, and the raised portion 211 is used to connect the shell structure 1 and the first lens 21, and to space the incident surface of the first lens 21 from the shell surface of the shell structure 1, that is, the raised portion 211 makes the incident surface of the first lens 21 higher than the shell structure 1 at the maximum effective aperture along the radial outward direction of the optical axis. In some embodiments, the raised portion 211 is a flange arranged around the edge of the first lens 21, which can space the first lens 21 from the shell surface of the shell structure 1. Similar in principle, in other embodiments, the flange of the shell structure 1 arranged around the edge of the viewfinder window can also be used as the raised portion 211 for connecting the first lens 21.

[0089] In some embodiments, the incident surface of the first lens 21 is used for light incidence. By raising the incident surface of the first lens 21, the incident light L1 is raised relative to the shell structure 1. In this way, in conjunction with the refractive design of the lens, the light-transmitting portion 2 can obtain light at a larger angle, so that the overlapping area of ​​the two photos taken by the panoramic shooting device is larger, which is conducive to improving the accuracy of image stitching (the stitching of two images requires the matching of feature points in the overlapping area. The increase in the overlapping area can make it easier to match). In addition, the shielding of the incident light L1 by the shell structure 1 or the protrusions on the shell structure 1 can also be reduced.

[0090] Among them, the exit surface and the incident surface are two opposite surfaces of the lens, which are used for light exit and incident. The exit surface is located on the side facing the panoramic shooting device 900, and the incident surface is located on the side away from the panoramic shooting device 900. In some embodiments, the first lens 21 is integrally provided with the lifting portion 211, or the first lens 21 is fixedly connected with the lifting portion 211, which is not limited here. The lifting portion 211 may also not be provided, and the distance between the incident surface of the first lens 21 and the shell surface of the shell structure 1 is increased by setting the thickness of the edge of the first lens 21, so that the incident point of the incident light L1 is higher than the shell surface of the shell structure 1. The lifting portion 211 is also used to block light to prevent the light incident from the lifting portion 211 from entering the shell structure 1, causing stray light to affect the imaging of the shooting device.

[0091] In some embodiments, the raised portion 211 is transparent but is configured so that the incident light will not be refracted to the panoramic shooting device; or the raised portion is made of a light-shielding material (opaque material); and / or a light-shielding layer (e.g., a light-shielding film) is provided on the raised portion 211. When the raised portion 211 is light-shielded by attaching an opaque material, the raised portion 211 can be made of a light-transmitting material and be integrally provided with the first lens 21 to reduce production costs.

[0092] Reference Figure 6 and Figure 7 As shown, the light-transmitting portion 2 further includes a second lens 22, which is stacked with the first lens 21, wherein the first lens 21 is configured to refract the incident light L1 into the intermediate light L2; and the second lens 22 is configured to refract the intermediate light L2 into the outgoing light L3.

[0093] In some embodiments, the angle between the intermediate light L2 and the outgoing light L3 is greater than the angle between the incident light L1 and the outgoing light L3, and in the radially outward direction of the optical axis, the incident point of the incident light L1 is higher than the exit point of the intermediate light L2, and the incident point of the intermediate light L2 is higher than the exit point of the outgoing light L3. It can be understood that the first lens 21 performs the first refraction, at which time the angle between the intermediate light L2 and the incident light L1 is greater than the first preset angle, and then performs the second refraction through the second lens 22, at which time the angle between the intermediate light L2 and the outgoing light L3 is greater than the first preset angle, and the second refraction of the first lens 21 and the second lens 22 can make the angle between the incident light L1 and the outgoing light L3 smaller than the first preset angle. The light-transmitting portion 2 can make the angle between the incident light L1 and the outgoing light L3 smaller than the first preset angle, wherein the smaller the first preset angle, the better, so as to ensure that the angle between the incident light L1 incident on the light-transmitting portion 2 and the optical axis of the light-transmitting portion 2 and the angle between the outgoing light L3 and the lens optical axis of the panoramic shooting device 900 are basically consistent, thereby reducing image distortion. Optionally, the first preset angle is less than 5 degrees. In other embodiments, the first preset angle is less than 2 degrees, which can further improve the imaging distortion problem caused by the light-transmitting portion 2.

[0094] Compared with refracting the incident light L1 into the outgoing light L3 at one time through a single lens, the first lens 21 and the second lens 22 used in this embodiment require a lower degree of refraction, so the lenses can be made thinner, effectively avoiding the problems of reduced resolution and increased weight caused by overly thick lenses.

[0095] In some embodiments, the material of the first lens 21 and the second lens 22 can be glass, or other light-transmitting materials, such as polycarbonate or polymethyl methacrylate. The materials of the first lens 21 and the second lens 22 can be the same or different.

[0096] In some embodiments, the first lens 21 and the second lens 22 can be set as concave lenses, the first lens 21 and the second lens 22 can both be set as concave lenses, or one of them can be set as a concave lens. The concave lens has a negative refractive force. When the incident light L1 greater than the first preset angle passes through the concave lens, its exit point will be lowered, thereby increasing the height difference between the incident point and the exit point, that is, the incident point of the incident light L1 can be further raised. However, the use of a concave lens will lead to poor imaging quality, reduced clarity and deformation. In order to further improve the imaging effect, at least one of the first lens 21 and the second lens 22 can be set as an aspherical lens, and by adjusting the curvature formula of the aspherical lens, the above-mentioned refraction requirements can be achieved, and it can improve the undesirable phenomena such as unclear images, distorted vision, narrow field of view, etc., and improve the imaging quality.

[0097] In some embodiments, the outer side of the light-transmitting portion 2 is convex outward and protrudes from the shell structure 1, and the inner side of the light-transmitting portion 2 is concave outward. Thus, the first lens 21 and the second lens 22 can be configured to be dome-shaped with a thickness at the maximum effective aperture greater than the center thickness, thereby expanding the field of view, wherein the first lens 21 and the second lens 22 can both be configured to be dome-shaped, or one of them can be configured to be dome-shaped.

[0098] Reference Figure 6 and Figure 7 As shown, the second lens 22 covers the viewfinder 17, and the edge of the first lens 21 and the edge of the second lens 22 are fitted together to form a heat-insulating cavity 23, thereby preventing dust, water vapor or other debris from entering the gap between the first lens 21 and the second lens 22, thereby improving the problem of affecting shooting.

[0099] Furthermore, the heat conduction efficiency of the heat insulating cavity 23 is lower than that of the light-transmitting portion 2, so that compared with the first lens 21 and the second lens 22 being completely fitted together, the heat conduction efficiency between the incident surface of the first lens 21 and the exit surface of the second lens 22 can be reduced by enclosing the heat insulating cavity 23, that is, the heat insulation performance is enhanced. When the waterproof housing 100 is used underwater, the temperature at the bottom of the water is relatively low, and the temperature inside the waterproof housing 100 is higher than the external water temperature due to the heat generated by the shooting device. Although the temperature of the incident surface of the first lens 21 is equal to the water temperature, due to the low heat conduction efficiency, the temperature of the exit surface of the second lens 22 will not drop too much within a certain period of time, so it can be avoided that the temperature of the second lens 22 is lower than the ambient temperature in the receiving cavity of the waterproof housing 100, resulting in the generation of fog.

[0100] In some embodiments, the heat-insulating cavity 23 is in a vacuum state, or the heat-insulating cavity 23 is filled with heat-insulating materials, and the heat-insulating materials may be heat-insulating gases, such as one or a combination of multiple gases selected from carbon dioxide, methane, argon, and krypton. It should be noted that when the waterproof housing 100 is a diving shell, the diving time may be as long as more than ten minutes, and a simple heat-insulating cavity 23 may produce fog. In this embodiment, the heat-insulating cavity 23 is set in a vacuum state to improve the heat-insulating effect and prevent the water vapor in the heat-insulating cavity 23 from causing fogging of the first lens 21 or the second lens 22.

[0101] Reference Figure 6 As shown, in one embodiment, the average curvature of the exit surface of the first lens 21 is greater than the average curvature of the incident surface of the second lens 22, so that the thickness in the center of the insulation cavity 23 is greater than the thickness at the edge, and the insulation cavity 23 is almond-shaped, so that the volume of the insulation cavity 23 is increased, and the distance between the central area of ​​the first lens 21 and the central area of ​​the second lens 22 is also increased, thereby enhancing the heat insulation performance of the light-transmitting portion 2.

[0102] Reference Figure 2-Figure 5 As shown, the shell structure 1 includes a first shell 11 and a second shell 12, the first shell 11 includes a first side wall 112 and a first bottom wall 111, and the second shell 12 includes a second side wall 122 and a second bottom wall 121. The first side wall 112 and the second side wall 122 both include a U-shaped portion and a C-shaped portion that are open and butt-connected, and the maximum width of the C-shaped portion is greater than the width of the U-shaped portion. In some embodiments, the first side wall 112 includes a U-shaped portion 113 and a C-shaped portion 114. The open ends of the U-shaped portion 113 and the C-shaped portion 114 are disposed toward each other and connected to each other to form the first side wall 112 in a closed loop. Similarly, the second side wall 122 also includes a U-shaped portion 123 and a C-shaped portion 124. The open ends of the U-shaped portion 123 and the C-shaped portion 124 are disposed toward each other and connected to form the second side wall 122 in a closed loop. When the first side wall 112 and the second side wall 122 are sealed and connected, the C-shaped portion 114 of the first side wall 112 and the C-shaped portion 124 of the second side wall 122 are correspondingly sealed and connected to form a sealed cavity 19 for accommodating the end of the panoramic shooting device 900 close to the viewfinder lens 904, and the U-shaped portion 113 of the first side wall 112 and the U-shaped portion 123 of the second side wall 122 are correspondingly sealed and connected to form a sealed cavity 19 for accommodating the end of the panoramic shooting device 900 close to the control key 905. A viewfinder window 17 is formed at a portion of the first bottom wall 111 connected to the corresponding C-shaped portion 114, and a viewfinder window 17 is formed at a portion of the second bottom wall 121 connected to the corresponding C-shaped portion 124, and the maximum radial dimensions of the two viewfinder windows 17 are both greater than the width of the U-shaped portion.

[0103] It can be understood that the corresponding C-shaped parts 114 and 124 are provided with circular viewfinder windows 17, which facilitates the first lens 21 and the second lens 22 to be sealed and arranged at the viewfinder windows 17, respectively, and the width of the U-shaped parts 113 and 123 is smaller than the maximum width of the C-shaped parts 114 and 124, so that the sealed cavity 19 defined by the first side wall 112 and the second side wall 122 is sufficient to accommodate the panoramic shooting device 900, while minimizing the volume of the waterproof housing 100, so as to facilitate the use of the panoramic shooting device 900 underwater. In addition, the width of the U-shaped parts 113 and 123 is smaller than the maximum width of the C-shaped parts 114 and 124, which can prevent the U-shaped parts 113 and 123 from blocking the sight of the first lens 21 and the second lens 22, that is, the field of view of the incident light of the first lens 21 and the second lens 22 is expanded to meet the need for a larger window.

[0104] See also Figure 3 and Figure 4 As shown, in some embodiments, an abutment portion 125 is convexly provided inside the first side wall 112 and the second side wall 122, and the abutment portion 125 is used to abut at least a portion of the circumferential surface 903 of the panoramic shooting device 900, so as to limit the panoramic shooting device 900 in the sealed cavity 19, so that the viewfinder lens 904 of the panoramic shooting device 900 is limited to correspond to the position of the light-transmitting portion 2, so as to avoid the panoramic shooting device 900 shaking relative to the first shell 11 and the second shell 12 during underwater shooting, resulting in the viewfinder lens 904 of the panoramic shooting device 900 being unable to align with the light-transmitting portion 2, thereby resulting in the framing angle being limited and the obtained image being blurred.

[0105] See also Figure 3 and Figure 4 As shown, in some embodiments, an anti-fog sheet 115 is clamped between the abutment portion 125 and the first side wall 112, which is used to absorb the moisture formed inside the sealed cavity 19, keep the sealed cavity 19 in a dry state, and prevent the first lens 21 and the second lens 22 from fogging. In some embodiments, the anti-fog sheet 115 can be set as a drying sheet, for example, it can be a plastic sheet with a drying function that is formed by compounding molecular sieves and polymer plastics and finally slicing. When the panoramic shooting device 900 works underwater, the environment is relatively humid, and moisture is easily generated in the waterproof cover 100. The anti-fog sheet 115 is set to keep the inside of the shell structure 1 dry, thereby strengthening the waterproof protection of the panoramic shooting device 900.

[0106] See also Figure 5 As shown, in some embodiments, a protruding hole 8 is provided on one side of the second side wall 122 of the waterproof cover 100, through which an anti-slip hand strap can be passed, and the other end of the anti-slip hand strap can be hung on the wrist or neck of a human body to prevent the waterproof cover 100 and the panoramic shooting device 900 from slipping out of hands and being lost during underwater shooting.

[0107] See also Figure 4 As shown, in some embodiments, the first housing 11 is a cavity structure with one end open, that is, the first housing 11 has an open end, and a receiving space is formed inside the first housing 11. In this embodiment, the first housing 11 is made of hard plastic injection molding, such as the first housing 11 can be made of polycarbonate (PC), phenolic resin, etc.

[0108] The second shell 12 is a cavity-type structure with one end open, that is, the second shell 12 has an open end, and a accommodating space is also formed inside the second shell 12. The second shell 12 is pivotally connected to the first shell 11. In other words, the second shell 12 can rotate on the first shell 11, so that the second shell 12 and the first shell 11 form a flip structure. The open end of the second shell 12 can be snapped into the open end of the first shell 11, and when the second shell 12 is snapped into the first shell 11, a sealed cavity 19 is formed inside the first shell 11 and the second shell 12, and the sealed cavity 19 can be used to accommodate the panoramic shooting device 900. In this embodiment, the second shell 12 is made of hard plastic injection molding, such as the second shell 12 can be injection molded of polycarbonate (PC), phenolic resin, etc.

[0109] Combined with reference Figure 8 and Fig. 9 As shown, the sealing ring 3 is injection molded at the open end of the first shell 11 and / or the open end of the second shell 12. As in the present embodiment, the molded sealing ring 3 is arranged around the peripheral side wall of the first shell 11 and / or the peripheral side wall of the second shell 12, and the sealing ring 3 is made of soft glue injection molding, such as the sealing ring 3 can be made of thermoplastic polyurethane (TPU), silicone, etc. When the sealing ring 3 is sealed between the first shell 11 and the second shell 12 which are injection molded by hard glue, it can avoid the first shell 11, the second shell 12 and the sealing ring 3 from offset, that is, the sealing ring seals the first shell and the second shell to form a sealed cavity for placing the panoramic shooting device. At the same time, the sealing ring made of soft glue injection molding is elastic to avoid deformation of the sealing ring due to long-term sealing. In other words, Figure 8 As shown, in this embodiment, when the second housing 12 is buckled with the first housing 11, the open end of the second housing 12 is inserted into the open end of the first housing 11. At this time, the sealing ring 3 is only injection-molded around the outer periphery of the second housing 12, and the sealing ring 3 abuts against the side wall of the first housing 11 adjacent thereto. In another embodiment, the sealing ring 3 is only injection-molded around the peripheral side wall of the first housing 11, and the sealing ring 3 abuts against the side wall of the second housing 12 adjacent thereto.

[0110] In another embodiment, there are two sealing rings 3, and one of the two sealing rings 3 is arranged around the peripheral side wall of the first shell 11, and the other of the two sealing rings 3 is arranged around the peripheral side wall of the second shell 12. In this embodiment, when the second shell 12 is buckled on the first shell 11, when the second shell 12 is buckled on the first shell 11, the sealing ring 3 arranged at the open end of the first shell 11 abuts against the side wall of the second shell 12 adjacent thereto, and the sealing ring 3 arranged at the open end of the second shell 12 abuts against the side wall of the first shell 11 adjacent thereto, and the heights of the two sealing rings 3 are different from the bottom of the first shell 11, so that the two sealing rings 3 are misaligned with each other and do not abut against each other, but directly abut against the side wall of the shell. Among them, the bottom of the first shell 11 can be the side thereof facing away from the opening. Of course, in other embodiments, when the second shell 12 is buckled on the first shell 11, the two sealing rings 3 abut against each other, and are squeezed and deformed to be close to each other.

[0111] That is to say, the sealing ring 3 corresponds to the first side wall 112 of the first shell 11 or the second side wall 122 of the second shell 12 adjacent thereto. Since the sealing ring 3 is flexible, the sealing ring 3 is squeezed and deformed to fit tightly against the first side wall 112 of the first shell 11 or the second side wall 122 of the second shell 12 to seal the gap at the joint between the first shell 11 and the second shell 12. When the panoramic shooting device 900 performs underwater shooting operations, water or other liquid media are prevented from entering the sealing cavity 19 and causing damage to the panoramic shooting device 900.

[0112] In the waterproof housing 100, the second housing 12 is pivotally connected to the first housing 11, so that the second housing 12 can rotate on the first housing 11, and a sealed cavity 19 can be formed for accommodating the panoramic shooting device 900. In some embodiments, the waterproof housing 100 includes a buckle assembly 6 for buckling the first side wall 112 and the second side wall 122, so as to detachably connect the first housing 11 and the second housing 12. When the second housing 12 is buckled on the first housing 11 and the buckle assembly 6 locks the first housing 11 and the second housing 12, the sealing ring 3 abuts against the first side wall 112 of the first housing 11 or the second side wall 122 of the second housing 12, and because the sealing ring 3 is flexible, the sealing ring 3 is squeezed and deformed to be close to the first side wall 112 of the first housing 11 or the second side wall 122 of the second housing 12, so as to seal the gap at the joint of the first housing 11 and the second housing 12, and when the panoramic shooting device 900 performs underwater shooting operations, water or other liquid media are prevented from entering the sealing cavity 19 to cause damage to the panoramic shooting device 900. The waterproof housing 100 provided by the present application, because the sealing ring 3 is injection molded at the open end of the first housing 11 and / or the open end of the second housing 12, the sealing ring 3 is integrally formed with the first housing 11 and / or the second housing 12, so that during the rotation of the second housing 12 on the first housing 11, the sealing ring 3 is not prone to local deformation or dislocation and other undesirable phenomena, and the waterproof sealing reliability of the waterproof housing 100 is high.

[0113] In some embodiments, Figure 8 and Fig. 9 As shown, a limiting portion 18 is provided at the open end of the first housing 11, and / or a limiting portion 18 is provided at a side of the second housing 12 close to the first housing, and the sealing ring 3 is injection molded at the limiting portion 18, so that the sealing ring 3 is injection molded at the open end of the first housing 11 and / or the open end of the second housing 12. The limiting portion 18 can limit the molding position of the sealing ring 3 in the first housing 11 and / or the second housing 12, further preventing the sealing ring 3 from being locally deformed or dislocated during long-term extrusion.

[0114] In some embodiments, Figure 8 and Fig. 9As shown, the limiting portion 18 is an annular groove, and the annular groove can be an L-shaped groove, a U-shaped groove or other shapes. And the annular groove opens on the outer surface of the first shell 11 and / or the outer surface of the second shell 12. As in the present embodiment, the annular groove can be integrally formed with the second shell 12 by extrusion, molding, etc., so as to simplify the molding process of the second shell 12 and the annular groove, and save the manufacturing cost of the second shell 12 and the annular groove. The sealing ring 3 is liquid silicone injection molded in the annular groove, that is, the sealing ring 3 is integrally co-molded in the annular groove by injection molding technology, so that the sealing ring 3 and the second shell 12 are formed into an integrated waterproof structure. During the rotation of the second shell 12, the sealing ring 3 is not prone to local deformation or dislocation and other undesirable phenomena, and the waterproof sealing reliability of the diving shell of the panoramic shooting device 900 is high. Because liquid silicone has excellent transparency, tear strength, resilience, yellowing resistance, thermal stability, water resistance, good air permeability, heat aging resistance and weather resistance, as well as moderate viscosity and easy operation, liquid silicone products are highly transparent, and you can see whether the finished product has defects such as bubbles.

[0115] In this embodiment, liquid silicone is used as the injection molding material of the sealing ring 3, and the softness and good plasticity of liquid silicone are utilized. The sealing ring 3 is easily deformed during the abutment process, and can be well fitted to the side wall of the first shell 11, so as to better seal the gap at the junction of the first shell 11 and the second shell 12. In other feasible embodiments, the annular groove can also be integrally formed with the first shell 11 by extrusion, molding, etc.; or there are two annular grooves, and the two annular grooves are respectively integrally formed with the first shell 11 and the second shell 12 by extrusion, molding, etc., and the setting method of the sealing ring 3 is similar to the above-mentioned embodiment, which will not be repeated here. In other embodiments, the limiting portion 18 can also be an annular table, which is arranged at the opening end of the first shell 11 and / or the opening end of the second shell 12. For example, the annular table is arranged at the opening end of the second shell 12, and the sealing ring 3 is liquid silicone injection molded on the annular table, which is similar to the above-mentioned embodiment, which will not be repeated here. It should be noted that in other feasible embodiments, the sealing ring 3 may be bonded to the annular groove by a dispensing process, or the sealing ring 3 may be directly clamped into the annular groove.

[0116] In order to improve the sealing and waterproof effect of the waterproof housing 100, in one embodiment, Figure 8 and Fig. 9As shown, the width of the annular groove opening end is smaller than the width of the annular groove bottom, that is, the annular groove is gradually expanded from its opening end toward the inside. On the one hand, the sealing ring 3 formed in the annular groove cannot be removed, so as to improve the molding stability of the sealing ring 3 and the first shell 11 and / or the second shell 12; on the other hand, the sealing ring 3 formed in the annular groove can be made thicker, and there is more deformation margin during the extrusion process of the sealing ring 3, which can improve the sealing and waterproof effect of the waterproof cover 100.

[0117] In some embodiments, Figure 8 and Fig. 9 As shown, the sealing ring 3 is injection molded on one side of the second housing 12 near its open end, that is, the sealing ring 3 is arranged around the open end of the second housing 12, or the sealing ring 3 is injection molded on one side of the first housing 11 near its open end, that is, the sealing ring is injection molded on one of the second housing or the first housing, and the other of the first housing or the second housing is provided with a snap-in groove. The outer surface of the sealing ring 3 has an annular protrusion 31, and when the second housing 12 is buckled on the first housing 11, the annular protrusion 31 abuts against the first side wall 112 of the first housing 11 close thereto. Since the annular protrusion 31 has better flexibility and greater deformation than the sealing ring 3 body during the extrusion process, when the second housing 12 is buckled on the first housing 11, the annular protrusion 31 is more easily deformed and closely adheres to the first side wall 112 of the first housing 11, so as to seal the gap at the joint of the first housing 11 and the second housing 12, and when the panoramic shooting device 900 performs underwater shooting operations, water or other liquid media are prevented from entering the sealing cavity 19 to damage the panoramic shooting device 900.

[0118] Furthermore, there are two annular protrusions 31. When the second shell 12 is buckled into the first shell 11, that is, the open end of the second shell 12 is buckled into the open end of the first shell 11, the two annular protrusions 31 are both in contact with the open end of the first shell 11. Since the two annular protrusions 31 are flexible, the two annular protrusions 31 are squeezed and deformed to fit tightly against the side wall of the first shell 11 to seal the gap at the joint between the first shell 11 and the second shell 12. When the panoramic shooting device 900 performs underwater shooting operations, water or other liquid media are prevented from entering the sealing cavity 19 to damage the panoramic shooting device 900.

[0119] In the above-mentioned waterproof cover 100, when the second shell 12 is buckled into the first shell 11, the two annular protrusions 31 are squeezed and fit against the side wall of the first shell 11, and the gap at the joint of the first shell 11 and the second shell 12 is double-sealed to further improve the sealing and waterproof effect of the waterproof cover 100.

[0120] In some embodiments, Fig. 9As shown, the first housing 11 is provided with a snap-in groove 117 on one side close to its open end, and the snap-in groove can also be provided on one side close to its open end of the second housing 12. As in the present embodiment, the snap-in groove 117 and the first housing 11 are integrally formed by extrusion, molding, etc., so as to simplify the molding process of the first housing 11 and the snap-in groove 117, and save the manufacturing cost of the first housing 11 and the snap-in groove 117. When the second housing 12 is buckled into the first housing 11, both the two annular protrusions 31 can abut against the snap-in groove 117 to seal the gap at the joint of the first housing 11 and the second housing 12, and when the panoramic shooting device 900 performs underwater shooting operations, water or other liquid media are prevented from entering the sealing cavity 19 to damage the panoramic shooting device 900.

[0121] Specifically, Fig. 9 As shown, the clamping groove 117 is an L-shaped groove, and two annular protrusions 31 are spaced apart and protrude from the outer surface of the sealing ring 3. When the second housing 12 is buckled onto the first housing 11, one of the two annular protrusions 31 abuts against one side wall of the clamping groove 117, and the other of the two annular protrusions 31 abuts against the other side wall of the clamping groove 117. Fig. 9 Taking the perspective shown as an example, one of the two annular protrusions 31 abuts against the side wall of the clamping groove 117, and the other of the two annular protrusions 31 abuts against the top wall of the clamping groove 117. In the above-mentioned waterproof housing 100, the two annular protrusions 31 can double-seal the gap at the joint of the first housing 11 and the second housing 12, so as to further improve the sealing and waterproof effect of the waterproof housing 100.

[0122] Reference Figure 10-12 As shown, a side wall of the shell structure 1 which is substantially parallel to the optical axis is provided with a key slot 4, and the key slot can be provided on the first side wall or the second side wall. The key slot is provided on the side wall to avoid the key slot blocking the light from entering the light-transmitting portion 2, thereby avoiding a reduction in the field of view. The shell structure 1 is also provided with a pressing member 5 which is at least partially provided in the key slot 4, and the pressing member 5 is used to move along the slot wall of the key slot 4 when pressed, and trigger the control key 905 of the panoramic shooting device 900, wherein the position of the key slot 4 can be set corresponding to the position of the control key 905 of the panoramic shooting device 900, and the specific structure is not limited here, as long as it can accommodate at least part of the pressing member 5 and enable the pressing member 5 to move along the slot wall of the key slot 4 when pressed, and trigger the control key 905 of the shooting device, this embodiment realizes underwater control of the panoramic shooting device 900 with poor waterproof capability.

[0123] In some embodiments, the key slot 4 is provided with a drainage structure 41, and the drainage structure 41 is used to discharge the liquid in the key slot 4 when the pressing member 5 is pressed. It should be noted that when the waterproof shell is placed in water, the key slot 4 will also be filled with water. The end of the pressing member 5 that contacts the finger is generally provided with a key cap. In this way, when the pressing member 5 is pressed, the resistance of the water in the key slot 4 to the key cap makes it difficult to press the pressing member 5. At a deeper bottom of the water, it may even cause the pressing member 5 to be unable to be used normally. In this embodiment, the key slot 4 is provided with a drainage structure 41, and the drainage structure 41 is used to discharge the liquid in the key slot 4 when the pressing member 5 is pressed, thereby improving the problem that the pressing member 5 of the waterproof shell is difficult to press. In this embodiment, the drainage structure 41 is not specifically limited, as long as it satisfies the requirement that the liquid in the key slot 4 is discharged when the pressing member 5 is pressed. For example, the drainage structure 41 is a drainage groove, a notch or a drainage hole provided on the groove wall, etc.

[0124] In some embodiments, the groove wall of the key slot 4 at least partially protrudes from the outer surface of the shell structure 1, and the drainage structure 41 is a notch provided in the side wall of the key slot 4. At this time, since the groove wall of the key slot 4 at least partially protrudes from the outer surface of the shell structure 1, and the key cap of the pressing member 5 also protrudes from the outer surface of the shell structure 1, the user can quickly find the protrusions, quickly locate and operate the pressing member 5 when using the waterproof shell. And since the side wall of the key slot 4 is provided with a notch, when the pressing member 5 is pressed, the notch can discharge the liquid in the key slot 4, thereby improving the problem that the pressing member 5 is difficult to press.

[0125] In some embodiments, the number of notches is at least two, and at least two notches are arranged at intervals along the circumference of the groove wall of the key groove 4. By providing multiple notches, the drainage efficiency is increased, and the resistance when the pressing member 5 is pressed is further reduced. Furthermore, at least two notches are arranged at equal intervals along the circumference of the key groove 4 to avoid interference between the discharged liquids when the pressing member 5 is pressed, which is conducive to further improving the problem that the pressing member 5 is difficult to press, for example, Fig.12 As shown, there are two notches, which are respectively located on both sides of the inner cavity of the key slot 4 to drain water to both sides. With this arrangement, when the pressing member 5 is pressed, the discharged liquid is discharged along the opposite sides of the key slot 4, and the water flows will not interfere with each other.

[0126] In some embodiments, the total area of ​​all the notches is greater than one quarter of the side wall area of ​​the key slot 4, and / or the total area of ​​all the notches is less than three quarters of the side wall area of ​​the key slot 4. The pressing member includes an end cap 51 and a pressing shaft 52 located in the key slot, one end of the pressing shaft 52 is connected to the end cap 51, and the other end corresponds to the position of the control key 905 of the panoramic shooting device 900, so that the control key 905 is pressed by pressing the end cap 51. The pressing member also includes an elastic member 53, which is sleeved on the pressing shaft 52, and one end of the elastic member 53 is connected to the end cap 51, and the other end is arranged on the shell structure 1, and is used to drive the end cap 51 to reset after pressing the end cap 51. In some embodiments, the shape of the end cap 51 can be adapted to the shape of the key slot 4, and the key slot 4 can be a cylindrical or any other cylindrical slot. In this case, the side wall area of ​​the key slot 4 can refer to the total area of ​​the side wall of the cylindrical or any other cylindrical slot.

[0127] In some embodiments, a through hole 54 connected to the accommodating cavity is provided at the bottom of the key slot 4, and the through hole 54 corresponds to the position of the control key 905 of the panoramic shooting device 900. For example, the control key 905 is located directly below the through hole 54, and one end of the pressing member 5 penetrates into the through hole 54. When the pressing member 5 is pressed, the pressing member 5 moves downward along the through hole 54 to trigger the control key 905 of the shooting device. Optionally, the key slot 4 is made of a rigid material, and the degree of deformation is small when subjected to force, thereby improving the problem of losing its limiting function due to deformation under force. Optionally, the key slot 4 can be a rectangular slot, a polygonal prism slot or a cylindrical slot, which is not limited here. Among them, "above" refers to the side close to the operator's finger touching the pressing member 5, and "below" refers to the side away from the operator's finger touching the pressing member 5, and is not used to limit this application.

[0128] In some embodiments, the pressing member 5 abuts against the bottom of the key slot 4. When the pressing member 5 is pressed, the pressing member 5 squeezes the bottom of the key slot 4, thereby causing the corresponding area of ​​the inner wall of the driving shell structure 1 to become concave. The concave area contacts and squeezes the control key 905 of the shooting device, thereby realizing the control of the control key 905.

[0129] See also Figure 13-Figure 15 As shown, the waterproof cover shell 100 includes a supporting device (not shown) connected to the shell structure 1, and the shell structure 1 is provided with a receiving portion 13 and a buffer portion 14, the receiving portion 13 forms a sealed cavity 19, and the panoramic shooting device 900 is placed in the sealed cavity 19 so as to be sealed and protected by the shell structure 1.

[0130] It should be noted that due to the force exerted by the supporting device on the receiving portion 13, the receiving portion 13 may be deformed, which may cause the panoramic shooting device 900 in the sealed cavity 19 to be squeezed, resulting in a decrease in the sealing performance of the receiving portion 13 (closed cavity structure) or the panoramic shooting device 900 falling (frame structure).

[0131] For the above problems, refer to Fig.13 As shown, in some embodiments, the buffer portion 14 is located between the receiving portion 13 and the supporting device to reduce deformation of the receiving portion 13 caused by the force of the supporting device on the receiving portion 13 .

[0132] In some embodiments, the buffer portion 14 may reinforce the receiving portion 13 to improve the strength of the receiving portion 13 , thereby reducing deformation of the receiving portion 13 . For example, the buffer portion 14 is connected to a side surface of the receiving portion 13 and reinforces the side surface.

[0133] In some embodiments, one end of the buffer portion 14 is connected to the supporting device, and the other end of the buffer portion 14 is connected to the receiving portion 13, and the force-bearing area of ​​the buffer portion 14 on the supporting device is smaller than the force-bearing area of ​​the receiving portion 13 on the buffer portion 14. The increase in the force-bearing area can be achieved by connecting the buffer portion 14 and the receiving portion 13 at multiple positions to achieve force dispersion. Taking the receiving portion 13 as a hexahedral structure as an example, the multiple position connections can all be located on one surface of the receiving portion 13, for example Fig.15 As shown, the buffer portion 14 is connected to four edge portions of one side of the receiving portion 13. Alternatively, the buffer portion 14 may be dispersedly disposed on different surfaces of the receiving portion 13.

[0134] Reference Fig.13 As shown, the receiving portion 13 includes a first wall 131, and the buffer portion 14 includes a second wall 142. The second wall 142 is substantially parallel to and spaced apart from the first wall 131 of the receiving portion 13, and the second wall 142 is provided with a connecting portion 141 for connecting a supporting device. In some embodiments, the second wall 142 and the first wall 131 may both be in the shape of long strips.

[0135] In some embodiments, the buffer portion 14 includes a plurality of third walls 143, one end of each third wall 143 is connected to the first wall 131, and the other end is connected to the second wall 142, and the plurality of third walls 143 are arranged to surround the first wall 131 along the circumference to form a partition space. For example, the third wall 143 includes two side edges, one end of the two side edges is connected to the two ends of the second wall 142 respectively, and the other ends of the two side edges are connected to the two ends of the first wall 131, and the first wall 131, the second wall 142 and the two side edges form a cylindrical body that is surrounded by a "mouth" shape. In some embodiments, the connection between the two side walls and the second wall 142 can be smoothly transitioned.

[0136] In some embodiments, see Fig.14 and Fig.15As shown, the buffer portion 14 further includes a connecting rib 144, which is located in the separation space and connects the first wall 131 and the second wall 142. Further, there are multiple connecting ribs 144, and the multiple connecting ribs 144 are arranged at intervals along the extension direction of the second wall 142; in some embodiments, adjacent connecting ribs 144 are arranged at a preset angle, and the preset angle is less than 180 degrees. The connecting rib 144 can increase the connection points between the first wall 131 and the second wall 142, so that the stress of the second wall 142 on the first wall 131 is dispersed. In some embodiments, the connecting rib 144 is a hard structure, and the rigidity of the buffer portion 14 is greater than or equal to that of the receiving portion 13.

[0137] In some embodiments, the buffer portion 14 and the receiving portion 13 are integrally formed, which improves the overall strength of the shell structure 1 and relatively reduces the manufacturing process, saving manpower and material resources.

[0138] In some embodiments, see Fig.14 As shown, the first shell 11 or the second shell 12 is provided with an anti-stop 145, and the anti-stop 145 is used to limit the position of the second shell 12 relative to the first shell 11 in the vertical direction along the fastening direction when the second shell 12 is fastened to the first shell 11. By limiting the position of the second shell 12 relative to the first shell 11 in the vertical direction along the fastening direction, that is, limiting the position of the second shell 12 relative to the first shell 11 in the direction parallel to the opening surface, the problem of sealing failure caused by the second shell 12 being offset relative to the first shell 11 in the direction of the opening surface is improved. In addition, the anti-stop 145 can also reduce the deformation amount of the opening of the second shell 12 relative to the first shell 11 in the direction of the opening surface, reduce the problem of a gap between the first shell 11 and the second shell 12 caused by deformation, and improve the problem of sealing failure between the first shell 11 and the second shell 12.

[0139] In some embodiments, see Fig.14 As shown, the first shell has an extension portion 147, and the extension portion 147 is a cavity-type structure with an opening at one end, and the opening faces the buffer portion 14. A reinforcing rib 146 is arranged in the cavity of the extension portion 147. The number of the reinforcing rib 146 can be multiple, and the reinforcing rib 146 can be arranged to be integrated with the anti-stop 145. Optionally, the structure of the reinforcing rib 146 is the same as that of the connecting rib 144, and the arrangement method is also the same.

[0140] Combined with reference Figure 2 , Fig.16 and Fig.17 As shown, the waterproof cover shell 100 includes a button 7 arranged on the shell structure 1, and the button 7 corresponds to the position of the control key 905 on the top surface 902 of the panoramic shooting device 900. When the button 7 is pressed, the button 7 can trigger the control key 905 to realize the control of the panoramic shooting device 900.

[0141] In some embodiments, the button 7 and the light-transmitting portion 2 are both located on the same side of the shell structure 1. Figure 2-Figure 4 As shown, exemplarily, the first shell 11 on the shell structure 1 is provided with a viewfinder window 17 and a through hole, the light-transmitting portion 2 covers the viewfinder window 17, and the button 7 covers the through hole, and the button 7 and the light-transmitting portion 2 are located on the same side of the shell structure 1. In other embodiments, the light-transmitting portion 2 and the button 7 may not be provided on the shell of the same shell structure 1, which is not limited here, as long as the button 7 and the light-transmitting portion 2 are located on the same side of the shell structure 1. Among them, the button 7 can be injection molded on the shell structure 1, or can be bonded to the shell structure 1.

[0142] It should be noted that, for the key 7 located on the same side as the light-transmitting portion 2, if the field of view of the panoramic shooting device 900 is large enough, for example, the field of view is greater than 120 degrees, the key 7 will block the framing light of the light-transmitting portion 2, and will be photographed by the framing lens 904 of the panoramic shooting device 900, causing a glitch. In the outward direction along the optical axis of the light-transmitting portion 2, the top surface 902 of the key 7 located on the same side as the light-transmitting portion 2 is lower than the bottom of the incident surface of the light-transmitting portion 2, so that the key 7 will not block the framing light of the light-transmitting portion 2, and will not be photographed by the framing lens 904 of the panoramic shooting device 900, causing a glitch.

[0143] In some embodiments, the button 7 can be injection molded on the shell structure 1 or bonded to the shell structure 1 .

[0144] See also Fig.16 and Fig.17 As shown, the shell structure 1 is provided with a through hole, and an inner boss 16 is provided on the inner wall of the through hole. The inner boss 16 is used to support the edge of the key 7 when the key 7 is pressed. In this embodiment, when the key 7 is installed in the through hole, the key 7 is located above the inner boss 16 and covers the through hole. The above here refers to the direction away from the sealed cavity 19. When the key 7 is pressed and the edge of the key 7 contacts the inner boss 16, the inner boss 16 supports the edge of the key 7 and prevents the edge of the key 7 from leaving the through hole. At this time, the middle part of the key 7 is bent downward by force to achieve the squeezing of the control key 905 of the panoramic shooting device 900, and after the key 7 is released, the middle part of the key 7 will rebound under the action of the elastic force. By providing the inner boss 16, the problem that the key 7 falls into the sealed cavity 19 due to pressing, which leads to the problem that it cannot be used normally, can be improved; and the key 7 can be fully deformed, and when pressed, it has good rebound performance and can rebound to the position before pressing, so as to enhance the pressing stability of the key 7. Optionally, the button 7 is made of an elastic material, such as rubber or plastic. Optionally, the inner boss 16 extends along the circumference of the through hole. Further, the inner boss 16 is annular. Optionally, the button 7 is bonded to the inner boss 16, for example, by glue. In other embodiments, the button 7 may be injection-molded to the inner boss 16.

[0145] It can be understood that when the key 7 is pressed, the edge of the key 7 will shrink toward the middle, so that there will be a tendency for relative sliding between the edge of the key 7 and the inner boss 16, affecting the bonding effect of the key 7 and the inner boss 16; and when the key 7 is not bonded to the inner boss 16, there will be relative sliding between the edge of the key 7 and the inner boss 16. If the sliding distance is too large, the edge of the key 7 will slide off the inner boss 16.

[0146] To solve the problem that the edge of the key 7 may slide off the inner boss 16, in some embodiments, as shown in FIG. Fig.16 and Fig.17 As shown, a first groove 71 corresponding to the inner boss 16 is provided on the side of the key 7 facing the inner boss 16, and a second groove 72 is provided at the bottom of the first groove 71; a rib 73 is provided on the side of the inner boss 16 facing the key 7, and the rib 73 is at least partially located in the second groove 72. That is, the key 7 is connected to the inner boss 16 in the through hole through the first groove 71, and the rib 73 and the second groove 72 are engaged with each other. When the key 7 is pressed, and the rib 73 contacts the side wall of the second groove 72 toward the center of the key 7, a relative sliding tendency is generated between the edge of the key 7 and the inner boss 16, and the rib 73 applies a force toward the edge of the key 7 to the side wall of the second groove 72, thereby weakening the relative sliding tendency and improving the problem of the edge of the key 7 sliding off the inner boss 16, so that the rib 73 is used to prevent the key 7 from sliding off the inner boss 16 when the key 7 is pressed; and when the key 7 is bonded to the inner boss 16, the arrangement of the groove and the rib 73 can enhance the bonding effect between the key 7 and the inner boss 16, enhance the connection strength, and improve the connection stability between the edge of the key 7 and the inner boss 16. Optionally, the first groove 71, the second groove 72 and the rib 73 are annular, and the cross section is rectangular along the circumferential direction.

[0147] To enhance the rebound effect of button 7, Fig.16 and Fig.17 As shown, the waterproof cover 100 further includes a cantilever 10, and the cantilever 10 is used to apply a force to restore the deformation to the key 7 when the key 7 is pressed and the key 7 is deformed. In this embodiment, the cantilever 10 is fixed to the inner wall of the through hole, extends in the direction toward the center of the through hole, and the cantilever 10 is located below the key 7, and the below here refers to the direction toward the sealed cavity 19. When the key 7 is pressed and the cantilever 10 contacts the key 7, the key 7 is deformed and squeezes the cantilever 10 to deform the cantilever 10. Under the action of its own resilience, the cantilever 10 applies a force to restore the deformation to the key 7, thereby enhancing the rebound effect of the key 7. Optionally, the key 7 is bonded to the cantilever 10.

[0148] In some embodiments, Fig.16As shown, the cantilever 10 includes a first part 101 and a second part 102. When viewed along the direction in which the key 7 and the cantilever 10 are arranged, the first part 101 is located in the center of the key 7; one end of the second part 102 is connected to the first part 101, and the other end of the second part 102 away from the first part 101 is connected to the shell structure 1, for example, fixedly connected to the inner wall of the through hole. Among them, the first part 101 is used to contact the key 7, and the second part 102 is used to provide elastic force to the first part 101. When the key 7 is pressed, the center of the key 7 sinks the most relative to other positions. Therefore, by setting the first part 101 in the center of the key 7, the rebound force of the cantilever 10 on the key 7 acts on the center of the key 7, giving full play to the rebound effect of the cantilever 10; and the center of the key 7 is the position where the finger presses. By setting the first part 101 in the center of the key 7, it can be supported between the control key 905 and the finger, so that the control key 905 is easier to be pressed, thereby obtaining a better pressing feel.

[0149] Further, such as Fig.16 As shown, along the extension direction of the cantilever 10, the cross-sectional area of ​​the first part 101 is greater than the cross-sectional area of ​​the second part 102, that is, the cross-sectional area of ​​the second part 102 is smaller than the cross-sectional area of ​​the first part 101. In this embodiment, the first part 101 is disc-shaped, the second part 102 is strip-shaped, and along the direction in which the cantilever 10 and the key 7 are arranged, the thickness of the first part 101 and the second part 102 are equal. By setting the first part 101 in a disc shape, it is better to contact with the control key 905 of the panoramic shooting device 900; and when pressing the key 7, the disc-shaped first part 101 is supported under the finger, which has a better support effect and improves the pressing feel; by setting the second part 102 in a strip shape, it has a smaller cross-sectional area, is easier to bend under force, and has a larger bending range, which improves the problem that the key 7 is difficult to press due to the excessive rigidity of the cantilever 10, and improves the problem that the key 7 has a small key travel due to the excessive rigidity of the cantilever 10.

[0150] In some embodiments, Fig.17 As shown, a protrusion 74 is provided on the side of the button 7 facing the cantilever 10. In this embodiment, the protrusion 74 surrounds the edge of the cantilever 10 to clamp the cantilever 10 and limit the relative position between the cantilever 10 and the button 7. Optionally, the protrusion 74 is bonded to the cantilever 10 to further enhance the bonding effect between the cantilever 10 and the button 7 and enhance the connection strength.

[0151] The present application provides a shooting device, including a panoramic shooting device 900 and the above-mentioned waterproof housing 100, wherein the panoramic shooting device 900 is provided with a viewfinder lens 904, and the panoramic shooting device 900 is completely sealed and wrapped in the waterproof housing 100, so as to provide waterproof protection for the panoramic shooting device 900 when used in water. At the same time, at least two light-transmitting parts 2 are provided to cover the viewfinder lens 904, and the fields of view of at least two light-transmitting parts 2 overlap, and the sum of the field of view angles of the non-overlapping fields of view is 360 degrees, so as to allow external light to enter the sealed cavity 19, and the shooting device can perform panoramic 360-degree framing shooting through the light-transmitting parts 2, that is, the light-transmitting parts 2 can play a role in increasing the shooting viewing angle, and the viewing angle after framing by at least two light-transmitting parts 2 is 360 degrees, and the panoramic 360-degree framing shooting can be achieved without rotating the panoramic shooting device 900 to a certain angle to shoot again. In some embodiments, the shooting device is also provided with a sealing ring and other structures to enhance the sealing effect of the waterproof cover shell 100, and a buffer portion 14 is also provided to reduce the deformation of the shell structure 1 caused by the force of the supporting device on the shell structure 1, and a pressing member 5 and a button 7 and other structures are also provided to facilitate the operation of the control key 905 of the shooting device underwater.

[0152] In some embodiments, the shooting device includes a panoramic imaging component and a processor, the panoramic imaging component is configured to shoot a panoramic video or a panoramic picture, the processor is connected to the panoramic imaging component, and the processor is configured to eliminate the supporting device in the panoramic video or the panoramic picture. Among them, the supporting device supports the shell structure 1. The panoramic imaging component can be a panoramic camera or a panoramic lens, which has a large field of view and can shoot panoramic videos or panoramic pictures. Eliminating the supporting device in the panoramic video or panoramic picture can be achieved as long as the field of view requirements and the size requirements of the supporting device are met. The specific principle is not repeated here.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
