[0041] In addition, it is required to understand the present application not only through the actual terms used, but also through the meanings implied by each term.

[0042] The technical solutions provided by each embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0043] An embodiment of the present application provides an explosion-proof camera device. Referring to Figures 1 to 11 , the explosion-proof camera device 1 provided by the embodiment of the present application includes: a first housing assembly 11, a plurality of first camera modules 12, a second housing assembly 21, a third housing assembly 31, and a second camera module 32.

[0044] It should be noted that the plurality of first camera modules 12 can be arranged in the first housing assembly 11. The second camera module 32 can be arranged in the third housing assembly 31. The third housing assembly 31 can be indirectly connected to the first housing assembly 11 through the second housing assembly 21, so that the components of the explosion-proof camera device 1 are connected together.

[0045] Exemplarily, the first camera module 12 can include an optical lens, a photosensitive element, etc. The second camera module 32 can include an optical lens, a photosensitive element, etc. Further, when the second camera module 32 has an autofocus function, the second camera module 32 can further include a focusing motor. It should be noted that the specific structure of the second camera module 32 can refer to the related art, and the embodiment of the present application does not limit the specific structure of the second camera module 32, and the specific structure and its working principle of the second camera module 32 will not be elaborated here.

[0046] In the embodiment of the present application, the second housing assembly 21 is rotatably connected to the first housing assembly 11 around a first axis 1a. The plurality of first camera modules 12 are circumferentially distributed in the first housing assembly 11 around the first axis 1a. Referring to Figure 7 , Figure 9 and Figure 10, the first housing assembly 11 is provided with a plurality of third through holes 1113 circumferentially distributed around the first axis 1a. Each third through hole 1113 is provided with a third light-transmitting member 1114 correspondingly. The third light-transmitting member 1114 is threadedly connected to the hole wall of the corresponding third through hole 1113. The light-incident parts of the first imaging modules 12 are correspondingly opposite to the third light-transmitting members 1114. In this way, the threaded connection explosion protection can be achieved by the threaded connection between the third light-transmitting member 1114 and the hole wall of the corresponding third through hole 1113, so as to improve the explosion-proof performance of the first housing assembly 11.

[0047] Reference Figure 2 , exemplarily, the number of the first imaging modules 12 is 8, and the 8 first imaging modules 12 are circumferentially distributed around the first axis 1a. Of course, in other embodiments, the number of the first imaging modules 12 can also be other numbers, which will not be listed one by one here. In this way, the images at multiple angles can be obtained by arranging a plurality of first imaging modules 12.

[0048] The third housing assembly 31 is connected to the second housing assembly 21. Exemplarily, the third housing assembly 31 can be fixedly connected to the second housing assembly 21. Alternatively, the third housing assembly 31 can be rotatably connected to the second housing assembly 21 so that the third housing assembly 31 can rotate relative to the second housing assembly 21 to adjust the orientation of the second imaging module 32.

[0049] Reference Figures 3 to 5 , the third housing assembly 31 includes a first housing 311 and a first cover 312. The first housing 311 is provided with a first through hole 3111. The first cover 312 seals the first through hole 3111 and is connected to the first housing 311. The first cover 312 and the first housing 311 enclose a first accommodating area. The first cover 312 is provided with a first convex ring 3121 extending along the hole wall of the first through hole 3111, and the first convex ring 3121 fits with the hole wall of the first through hole 3111. In this way, the sealing effect of the joint between the first cover 312 and the first housing 311 can be improved by the fitting between the first convex ring 3121 and the hole wall of the first through hole 3111.

[0050] The second imaging module 32 is disposed in the first accommodating area. The first cover 312 is provided with a first light-transmitting area 3122, and the light-incident part of the second imaging module 32 faces the first light-transmitting area 3122. The second imaging module 32 can obtain external images through the first light-transmitting area 3122.

[0051] It should be noted that those skilled in the art generally refer to the combination of the third housing assembly 31 and the second imaging module 32 as a detail ball. The second imaging module 32 can rotate relative to the first housing assembly 11 along with the third housing assembly 31 to adjust the orientation of the second imaging module 32, so that the target area can be monitored intensively according to requirements.

[0052] In this way, in the embodiments of the present application, since the first cover body 312 seals the first through hole 3111, the first cover body 312 is provided with a first convex ring 3121 extending along the hole wall of the first through hole 3111, and the first convex ring 3121 fits with the hole wall of the first through hole 3111. In this way, the sealing effect of the joint between the first cover body 312 and the first housing 311 can be improved by the way that the first convex ring 3121 fits with the hole wall of the first through hole 3111, so as to improve the explosion-proof performance of the third housing assembly 31. In addition, the threaded connection explosion protection can be realized by the way that the third light-transmitting member 1114 is threadedly connected with the hole wall of the corresponding third through hole 1113, so as to improve the explosion-proof performance of the first housing assembly 11.

[0053] Reference Figure 5 , in some embodiments, the first cover body 312 is provided with a first mounting hole 3123, a first light-transmitting member 3124 is arranged in the first mounting hole 3123, and a first light-transmitting area 3122 is formed in the area where the first light-transmitting member 3124 is located. The hole wall of the first mounting hole 3123 is provided with a second convex ring 3125, and the surface of the second convex ring 3125 facing the second camera module 32 abuts against the first light-transmitting member 3124. In this way, the first light-transmitting member 3124 can be prevented from falling out of the first mounting hole 3123.

[0054] Furthermore, a first bonding rubber ring 3126 is arranged between the circumferential side wall of the first light-transmitting member 3124 and the hole wall of the first mounting hole 3123. In other words, during the process of assembling the first light-transmitting member 3124 into the first mounting hole 3123, an adhesive can be arranged between the first light-transmitting member 3124 and the hole wall of the first mounting hole 3123, and the adhesive forms the first bonding rubber ring 3126 after solidifying. In this way, the sealing performance of the joint between the first mounting hole 3123 and the first light-transmitting member 3124 can be improved by arranging the first bonding rubber ring 3126 between the circumferential side wall of the first light-transmitting member 3124 and the hole wall of the first mounting hole 3123, so as to improve the explosion-proof performance of the third housing assembly 31.

[0055] Reference Figure 4 and Figure 5, in some embodiments, the first housing 311 is further provided with a second through hole 3112. The third housing assembly 31 further includes a second cover 313, and the second cover 313 is threadedly connected to the hole wall of the second through hole 3112 to block the second through hole 3112. When the second cover 313 is separated from the second through hole 3112, the second through hole 3112 forms an access opening. In other words, the first housing 311 is provided with a second through hole 3112, and the second through hole 3112 is an access opening. When there is no need for maintenance, the second through hole 3112 is blocked by the second cover 313. Specifically, the second cover 313 is threadedly connected to the hole wall of the second through hole 3112 to achieve explosion isolation through threaded connection, so as to improve the explosion-proof performance of the third housing assembly 31.

[0056] In the related art, a spherical light-transmitting cover is externally covered on the detail sphere of the explosion-proof camera device, and the spherical light-transmitting cover is used to make the detail sphere meet the explosion-proof function requirements. However, after the outer surface of the spherical light-transmitting cover is covered with pollutants, manual cleaning is required. Therefore, the explosion-proof camera device in the related art has the problem of inconvenient use. The embodiments of the present application provide the following solutions to solve this problem.

[0057] Reference Figure 3 , in some embodiments, the first cover 312 is provided with a wiper 33, and the wiper 33 is used to scrape the surface of the first light-transmitting area 3122 facing away from the second imaging module 32. It should be noted that the structure of the wiper 33 can refer to the wiper in the related art. Therefore, the structure and working principle of the wiper 33 will not be elaborated here.

[0058] Adopting the solution provided by the embodiments of the present application, the second imaging module 32 can obtain environmental images through the first light-transmitting area 3122 of the first cover 312. Compared with the related art, the spherical light-transmitting cover is cancelled. Further, the first cover 312 is provided with a wiper 33. Therefore, the wiper 33 can be used to clean the surface of the first light-transmitting area 3122 facing away from the second imaging module 32 to replace the manual cleaning method, thereby improving the usability of the explosion-proof camera device 1.

[0059] Reference Figures 3 to 5 , in some embodiments, the explosion-proof camera device 1 further includes an infrared fill light 34. The first cover 312 is provided with a second light-transmitting area 3127, the infrared fill light 34 is disposed in the first accommodating area, and the light-emitting part of the infrared fill light 34 faces the second light-transmitting area 3127. In this way, the night shooting effect of the explosion-proof camera device 1 can be improved by adding an infrared fill light 34.

[0060] Further, the first cover body 312 is provided with a second mounting hole, and a second light-transmitting member is disposed in the second mounting hole. The area where the second light-transmitting member is located forms a second light-transmitting area. The hole wall of the second mounting hole is provided with a fourth convex ring, and the surface of the fourth convex ring facing the infrared supplementary light 34 abuts against the second light-transmitting member. In this way, the second light-transmitting member can be prevented from falling out of the second mounting hole.

[0061] Further, a second adhesive rubber ring is provided between the circumferential side wall of the second light-transmitting member and the hole wall of the second mounting hole. In other words, during the process of assembling the second light-transmitting member into the second mounting hole, an adhesive can be provided between the circumferential side wall of the second light-transmitting member and the hole wall of the second mounting hole, and after the adhesive solidifies and forms, it becomes the second adhesive rubber ring. In this way, the sealing performance of the joint between the second mounting hole and the second light-transmitting member can be improved by providing the second adhesive rubber ring between the circumferential side wall of the second light-transmitting member and the hole wall of the second mounting hole, so as to improve the explosion-proof performance of the third housing assembly 31.

[0062] Reference Figure 1 , in some embodiments, the third housing assembly 31 and the second housing assembly 21 are rotatably connected about a second axis 1b, and the second axis 1b is not parallel to the first axis 1a. Exemplarily, the second axis 1b is perpendicular to the first axis 1a. For example, the first axis 1a is vertically arranged and the second axis 1b is horizontally arranged. In this way, it is convenient to adjust the orientation of the second camera module 32 disposed in the third housing assembly 31.

In this way, the sealing effect of the joint between the second housing 111 and the third housing 112 can be improved by the way that the outer peripheral surface of the third convex ring 1115 fits with the side wall of the second opening 1122.

[0065] Reference Figure 7 and Figure 11, in some embodiments, a recessed portion 1124 recessed toward the second side 1121 is provided on the third side 1123 of the third housing 112, wherein the third side 1123 faces away from the second side 1121.
