DETAILED DESCRIPTION

[0039] To make the objectives, technical solutions, and advantages of this application more clearly understood, the present application is further described below with reference to the accompanying drawings and examples. It is apparent that the described examples are only a portion of the embodiments of this application, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the examples in this application are intended to fall within the scope of protection of this application.

[0040] A camera, which may be an air-cooled camera, includes an inner shell 10 and an outer shell 20 extending along a first direction X and coaxially arranged, a first flange 30 and a second flange 40 arranged between the inner shell 10 and the outer shell 20, and a front cover assembly 50.

[0041] The outer shell 20 is placed outside the inner shell 10, and the inner shell 10 and the outer shell 20 are opened at both ends along the first direction X. Along the first direction X, the first flange 30 and the second flange 40 are respectively located at both ends of the inner shell 10, and the first flange 30 and the second flange 40 respectively seal the annular space between the inner shell 10 and the outer shell 20, so that an annular first accommodating space 100 is formed between the inner shell 10 and the outer shell 20.

[0042] The housing 20 includes a connecting portion 21 axially protruding from the first flange 30, and the front cover assembly 50 is connected to the connecting portion 21 by abutting the outer circumferential wall of the front cover assembly 50 against the inner circumferential wall of the connecting portion 21; wherein, the front cover assembly 50 includes a mounting panel 51 perpendicular to the first direction X, and the mounting panel 51 is provided with at least a shooting window 511. On the side of the mounting panel 51 facing away from the first flange 30, an insertion portion 52 is extended at the circumferential end portion of the mounting panel 51 along the first direction X, and the portion of the insertion portion 52 located at the upper end of the shooting window 511 is formed with a accommodating groove 53 by radially inwardly concave, and the bottom plate 54 of the accommodating groove 53 is provided with an air outlet groove 55 for forming an air curtain, and the bottom plate 54 and the air outlet groove 55 extend along the second direction Y, and the second direction Y is the width direction of the shooting window 511.

[0043] When the front cover assembly 50 is connected and installed with the housing 20 , the inserting portion 52 is used to circumferentially abut against the connecting portion 21 , and the accommodating groove 53 is used to form a second accommodating space 200 between the inserting portion 52 and the connecting portion 21 .

[0044] Moreover, along the first direction X, the second flange 40 is provided with an air inlet hole 41, the first flange 30 is provided with an air outlet hole 31, and the mounting panel 51 is provided with a through air hole 513. The through air hole 513 extends from the mounting panel 51 toward the side of the first flange 30 to the accommodating groove 53, and the through air hole 513 is coaxially arranged with the air outlet hole 31; so that when the front cover assembly 50 is connected and installed with the connecting part 21, the cooling gas flows from the air inlet hole 41 through the first accommodating space 100 and the second accommodating space 200 in sequence, and blows the shooting window 511 through the air outlet groove 55.

[0045] The camera of this embodiment specifically relates to an air-cooled camera, which includes an inner shell 10, an outer shell 20, a first flange 30, a second flange 40 and a front cover assembly 50; wherein the first direction X is the length direction of the air-cooled camera, the second direction Y is the width direction of the air-cooled camera, and the third direction Z is the height direction of the air-cooled camera; for convenience of description, when the air-cooled camera is placed horizontally, the first direction X is a horizontal direction, the width direction of the air-cooled camera (i.e., the second direction Y) is another horizontal direction perpendicular to the first direction X, and the height direction of the air-cooled camera (i.e., the third direction Z) is a vertical direction.

[0046] Among them, regarding the inner shell 10 and the outer shell 20, referring to Figures 1a and 1b, the inner shell 10 and the outer shell 20 are, for example, cylindrical with openings at both ends. The inner shell 10 and the outer shell 20 are coaxially arranged, and the outer shell 20 is externally placed on the inner shell 10. In this way, an annular space is formed between the inner shell 10 and the outer shell 20, and extends in a first direction (i.e., the axial direction of the inner shell and the outer shell).

[0047] Among them, regarding the first flange 30 and the second flange 40, please refer to Figure 1b and Figure 2. Along the two ends of the first direction X, the first flange 30 and the second flange 40 are respectively provided between the inner shell 10 and the outer shell 20. For example, the front end of the camera is the first flange 30, and the rear end of the camera is the second flange 40. In addition, the two flanges respectively seal the annular space between the inner shell 10 and the outer shell 20. It can be understood that, in this way, the sealing of the two flanges can form an annular first accommodating space 100 between the inner shell 10 and the outer shell 20.

[0048] Regarding the front cover assembly, first referring to FIG. 1 b , at one end where the first flange 30 is mounted, the housing 20 includes a connecting portion 21 axially protruding from the first flange. The connecting portion 21 is a circumferential wall of the housing 20 having a certain width. The connecting portion 21 is used for plugging and mounting the front cover assembly 50.

[0049] 6 to 10 , the front cover assembly 50 includes a mounting panel 51. The mounting panel 51 is, for example, in a circular shape perpendicular to the first direction X. The mounting panel 51 is used to mount the lens assembly 91 and the like. Thus, a shooting window 511 is provided in, for example, the middle region of the mounting panel 51. Of course, a fill light window 512 may also be provided at the lower end of the shooting window 511.

[0050] 8 , an insert portion 52 extends along the first direction X from the circumferential end of the mounting panel 51 on a side facing away from the first flange 30. The portion of the insert portion 52 located above the photographing window 511 is radially recessed to form a receiving groove 53. A bottom plate 54 of the receiving groove 53 extends along the second direction Y (i.e., the width of the camera) and is provided with an air outlet groove 55 also extending along the second direction Y. In other words, the front cover assembly 50 forms a receiving groove 53 in the area above the photographing window 511 by radially recessing the insert portion 52. The upper end of the receiving groove 53 is open.

[0051] In this way, combined with Figure 13, when the front cover assembly 50 is inserted into the connecting part 21 of the outer shell 20, the mounting panel 51 can be axially abutted against the first flange 30, the insertion part 52 can be circumferentially abutted against the abutting part of the outer shell 20, and the upper end opening of the accommodating groove 53 is covered by the connecting part 21 to form a second accommodating space 200.

[0052] Regarding the air inlet hole 41, referring to FIG. 13 , the air inlet hole 41 is provided on the second flange 40, that is, the second flange 40 provided at the rear of the air-cooled camera. Furthermore, the first flange 30 is provided with an air outlet hole 31, and the mounting panel 51 is provided with a through-hole 513. The through-hole 513 extends along the first direction X from the mounting panel 51 toward one side of the first flange 30 to the accommodating groove 53. In addition, the air outlet hole 31 of the first flange 30 and the through air hole 513 of the mounting panel 51 are coaxially arranged; that is, by arranging the air outlet hole 31 and the through air hole 513, the first accommodating space 100 and the second accommodating space 200 can be connected; in this way, the cooling gas first flows into the first accommodating space 100 from the air inlet hole 41 at the rear of the air-cooled camera, and then flows into the second accommodating space 200 through the air outlet hole 31 and the through air hole 513 in sequence, and is ejected from the air outlet groove 55 in the second accommodating space 200. Since the air curtain opening is located at the upper part of the shooting window 511, the shooting window 511 is purged from the upper part of the shooting window 511.

[0053] Thus, compared with the circular purge shooting window 511, the air outlet slot 55 of the air-cooled camera in this embodiment adopts a long rectangular purge with a large purge area, which can significantly improve the negative pressure phenomenon of the shooting window and enhance the cooling and dust removal effects of the shooting window 511.

[0054] In addition, the air-cooled camera of this embodiment has a simple structure and is easy to assemble; for example, the two flanges are first welded to the inner shell 10, and then the outer shell 20 is sleeved and welded to the two flanges respectively, and then the front cover assembly 50 is plugged in and fastened with screws.

[0055] The embodiment of the present application provides an air-cooled camera, which includes a coaxial inner shell 10 and an outer shell 20. The two ends of the annular space between the inner shell 10 and the outer shell 20 are sealed with a first flange 30 and a second flange 40, respectively. In this way, a first accommodating space 100 is formed between the inner shell 10 and the outer shell 20; then, a front cover assembly 50 is plugged into the connecting portion 21 of the outer shell 20, and an accommodating groove 53 is radially concave in the plug-in ring 52 of the front cover assembly 50. The accommodating groove 53 and the connecting portion 21 of the outer shell 20 form a second accommodating space 2 00; and, the first accommodating space 100 and the second accommodating space 200 are connected through the air outlet hole 31 of the first flange 30 and the through air hole 513 of the mounting panel 51 of the front cover assembly 50, and the second flange 40 at the rear of the camera is provided with an air inlet hole 41, so that the cooling gas can flow through the first accommodating space 100 and the second accommodating space 200 in sequence through the air inlet hole 41, and blow the shooting window 511 on the mounting panel 51 through the air outlet groove 55 on the bottom plate of the second accommodating space 200. The structure is simple and the installation and assembly are convenient.

[0056] In addition, the bottom plate 54 of the second accommodating space 200 and the air outlet groove 55 on the bottom plate 54 extend along the width direction of the camera, so that the cooling gas (which is also the purge medium) can be blown from the upper part of the shooting window 511 to cool it down, thereby avoiding the occurrence of negative pressure in the shooting window 511 and achieving good cooling and dust removal effects.

[0057] In one possible implementation, in the annular cross-section of the second flange 40 , the air inlet hole 41 is located in the middle of the arc-shaped cross-section portion at the lower end of the shooting window 511 .

[0058] Specifically, in combination with Figure 4, the air intake hole 41 can be located in the arc-shaped cross-sectional portion of the lower half of the second flange 40; in other words, the cross-section of the second flange 40 perpendicular to the first direction X is annular, and the air intake hole 41 is specifically located in the middle position of the arc-shaped cross-sectional portion at the lower end of the shooting window 511 relative to the mounting panel 51; that is, at the tail of the air-cooled camera, the cooling gas enters the first accommodating space 100 from the lower end of the air-cooled camera.

[0059] 4 , the air inlet hole 41 may be located at the lower end of the second flange 40 and centrally arranged; that is, relative to the camera, the cooling gas enters the first accommodating space 100 from the lower end of the rear of the camera.

[0060] In a specific embodiment, in conjunction with Figure 4, the outer shell 20 is a cylindrical sleeve extending along the first direction X; the inner shell 10 includes a first flat plate 11 and a second flat plate 12 arranged opposite to each other, the first flat plate 11 and the second flat plate 12 extending along the first direction X, the first flat plate 11 and the second flat plate 12 are perpendicular to the third direction Z, and the first flat plate 11 and the second flat plate 12 are connected to form a circumferentially closed sleeve by a pair of arc-shaped walls 13 extending along the first direction X, so that the outer surfaces of the first flat plate 11 and the second flat plate 12 form a guide plane for the cooling gas.

[0061] It can be seen that, unlike the full-circular structure, the upper and lower ends of the inner shell 10 in this embodiment are configured as flat plates extending along the first direction X, thereby effectively improving the smooth flow of cooling gas along the first direction X.

[0062] In a specific embodiment, first, with reference to FIG2 , a diverter plate 60 is provided in the first accommodating space 100 at a position near the air inlet through-hole 41 along the first direction X, and the diverter plate 60 is arranged perpendicular to the first direction X; then, with reference to FIG5 , the diverter plate 60 is located in the arc-shaped cross-sectional portion of the annular cross-section of the first accommodating space 100 relative to the lower end of the shooting window 511; and the diverter plate 60 is provided with a plurality of diverter holes 61, and the plurality of diverter holes 61 are arranged along the second direction Y so that the cooling gas is evenly distributed in the annular cross-sectional area of ​​the first accommodating space 100.

[0063] That is, in order to achieve better air-cooling, heat insulation and heat dissipation effects, this embodiment further provides a diverter plate 60 in the first accommodating space 100 .

[0064] 1a , 1b , 2 and 5 , the first accommodating space 100 is further provided with a diverter plate 60 , which is arranged perpendicular to the first direction X. Considering that the cross-section of the first accommodating space 100 perpendicular to the first direction X is annular, the diverter plate 60 is an arc-shaped plate with a certain width; and, in the annular cross-section of the first accommodating space 100 , the diverter plate 60 is located at the arc-shaped cross-section portion relative to the lower end of the shooting window 511 ; for example, referring to FIG. 5 , the diverter plate 60 is semicircular, and the radial inner end and radial outer end of the diverter plate 60 respectively abut the inner shell 10 and the outer shell 20 .

[0065] In addition, referring to Figure 5 , the diverter plate 60 is provided with a plurality of diverter holes 61, and the plurality of diverter holes 61 are arranged along the width direction (i.e., the second direction) of the shooting window 511; for example, in Figure 5 , three diverter holes 61 are provided, one of which is centered, and the other two are symmetrically distributed on both sides, or the diverter holes 61 are evenly distributed along the second direction Y, so that the cooling gas is evenly distributed in the annular cross-section of the first accommodating space 100.

[0066] It can be understood that by arranging the air inlet hole 41 at the lower end of the second flange 40 and arranging the diverter plate 60 in the first accommodating space 100, the cooling gas first flows into the lower end area of ​​the annular first accommodating space 100 from the air inlet hole 41, and then, due to the obstruction of the diverter plate 60, part of the cooling gas flows upward and flows through the upper end area of ​​the annular first accommodating space 100, and part of the cooling gas will pass through the diverter hole 61 of the diverter plate 60 and continue to flow in the lower end area of ​​the first accommodating space 100, so that the cooling gas can be evenly distributed in the annular cross-section of the first accommodating space 100, thereby improving the air-cooled heat insulation and heat dissipation effects.

[0067] It should be understood that the first accommodating space 100 circulates cooling gas. On the one hand, the cooling gas absorbs the heat from the high-temperature environment outside the air-cooled camera to provide insulation for the electronic components inside the air-cooled camera. On the other hand, the cooling gas also absorbs the heat generated by the electronic components inside the air-cooled camera to provide heat dissipation.

[0068] It can be seen that in order to achieve better heat conduction from the external high-temperature environment to the cooling gas, and from the internal electronic components to the cooling gas, the above-mentioned inner shell 10, outer shell 20 and two flanges usually need to be made of metal materials, while the front cover assembly can be made of high-temperature resistant plastic materials for easy processing to reduce costs.

[0069] In one possible implementation, in the annular cross-section of the first flange 30 , the air outlet hole 31 is located in the middle of the arc-shaped cross-section portion at the upper end of the shooting window 511 .

[0070] That is, similar to the air inlet through hole 41 , the air outlet through hole 31 may be located at the upper end of the first flange 30 and arranged in the center.

[0071] In one possible embodiment, the accommodating groove 53 is connected to a plug-in 70 for guiding air, and the plug-in 70 includes an arc-shaped cover 73, and the arc-shaped cover 73 has a first side wall 71 extending along the third direction Z on the side close to the first flange 30, and a second side wall 72 extending along the third direction Z on the other side of the arc-shaped cover 73 away from the first flange 30, so that the end of the plug-in 70 facing the base plate 54 is arranged in an open shape, and the third direction Z is the height direction of the camera; and when the plug-in 70 is inserted into the accommodating groove 53, the arc-shaped cover 73 is used to abut against the connecting portion 21, and the first side wall 71 is provided with an avoidance gap 74 to avoid the through air hole 513.

[0072] From the previous description, it can be seen that after the cooling gas flows into the air inlet hole 41 at the rear of the air-cooled camera, it first flows horizontally toward the front end of the air-cooled camera, then turns at the accommodating groove 53 (or the second accommodating space) of the front cover assembly and flows vertically downward through the air outlet groove 55. In this way, in order to better guide the cooling gas at the turning point, this embodiment adds a plug-in 70.

[0073] In general, referring to FIG. 6 and FIG. 11 , the plug-in unit 70 is used to be installed in the receiving groove 53 of the front cover assembly 50 .

[0074] Specifically, the plug-in 70 includes an arc-shaped cover 73 , the shape of which fits the missing portion of the insertion portion 52 due to the radial inward concave portion. In this way, when the plug-in 70 is inserted into the accommodating groove 53 , the arc-shaped cover 73 can fitly abut the connecting portion of the shell 20 .

[0075] A first side wall 71 and a second side wall 72 are respectively provided on the front and rear sides of the arc-shaped cover 73. The two side walls are, for example, arranged in parallel and both extend along the third direction Z; in other words, the two side walls extend along a plane perpendicular to the first direction X; in this way, the plug-in 70 is arranged with an open lower end; and when the plug-in 70 is inserted into the accommodating groove 53, the first side wall 71 close to the first flange 30 is provided with an avoidance notch 74 that avoids the through-hole 513, so that the cooling gas flows out of the through-hole 513 and then flows into the interior of the plug-in 70.

[0076] The material of the plug-in 70 may be but is not limited to silicone. The plug-in 70 is made of silicone material, which is conducive to close contact with the two side walls of the accommodating groove 53 along the first direction X, thereby increasing the sealing effect and reducing the risk of dust entering the interior of the camera.

[0077] In a specific embodiment, in combination with Figures 11 and 13, a rounded corner 75 for guiding air is provided on the inner side of the second side wall 72 and at a position corresponding to the center axis of the through air hole 513, so that the cooling gas flowing into the plug-in 70 from the through air hole 513 is guided to the air outlet groove 55 through the rounded corner 75.

[0078] Specifically, a rounded corner 75 is provided on the inner side of the second sidewall 72, distal from the first flange 30. This rounded corner 75 corresponds to the central axis of the through-hole 513. Thus, after the cooling gas flows from the through-hole 513 into the insert 70, the rounded corner 75 guides the cooling gas vertically downward toward the outlet slot 55, minimizing the impact on wind speed. By actively directing the cooling gas flow through the rounded corner 75, the cooling gas changes direction after colliding with a vertical sidewall arranged along the third direction Z, thereby reducing flow loss. This allows the cooling gas to maintain a high flow rate after passing through the outlet slot 55, thereby enhancing the purging effect on the photographing window 511.

[0079] In a specific embodiment, referring to Figures 11 and 13, a plurality of guide ribs 76 extending along the third direction Z are provided on the inner side of the second side wall 72 and away from the arc-shaped cover 73; wherein the plurality of guide ribs 76 are arranged in parallel, and the heights of the plurality of guide ribs 76 are gradually increased from the middle to both sides.

[0080] That is, a plurality of parallel guide ribs 76 are provided in the lower area of ​​the inner side of the second side wall 72 away from the first flange 30, and the height of the guide ribs 76 is distributed so that the height is low in the middle and high on both sides; for example, referring to Figure 11, the second side wall 72 is provided with four guide ribs 76, the two middle ones are low-position guide ribs 761, and the two sides are each a high-position guide rib 762. In this way, by providing the guide ribs 76, the cooling gas can be gathered.

[0081] In addition, referring back to Figures 6 and 11, the above-mentioned plug-in 70 is provided with a positioning groove 77 at one end facing the base plate, and then, a positioning rib 56 is provided on the base plate 54 to be plugged into the positioning groove 77. In this way, the plug-in 70 can be specifically installed in the accommodating groove 53 by plugging the positioning rib 56 into the positioning groove 77.

[0082] In one possible embodiment, in combination with Figures 8 to 10, the base plate 54 is perpendicular to the mounting panel 51, and the circumferential wall of the air outlet groove 55 formed on the base plate 54 is inclined relative to the third direction Z (i.e., the height direction of the camera) to guide the cooling gas to be sprayed to the shooting window 511.

[0083] That is, it can be understood that the bottom plate 54 of the accommodating groove 53 can be set vertically to the mounting panel 51, and then, the air outlet groove 55 on the bottom plate 54 is a long rectangle extending along the width direction of the camera. In order to guide the cooling gas to be sprayed to the shooting window 511, the circumferential wall of the air outlet groove 55 needs to be tilted relative to the vertical direction (that is, the third direction or the height direction of the camera); as for the specific tilt angle, it can be determined according to the specific structural dimensions.

[0084] For example, in combination with Figures 8, 9 and 10, the cross-section of the air outlet groove 55 perpendicular to the third direction Z is a rectangle. Among the two opposite long sides 551, the inclination angle B of the long side close to the mounting panel 51 can be 2 degrees, and the inclination angle A of the long side away from the mounting panel 51 can be 6 degrees; the two opposite short sides 552 of the air outlet groove 55 are inclined in a converging shape relative to the shooting window 511, and the inclination angle can be 1.5 degrees.

[0085] In one possible embodiment, the radial inner end and the radial outer end of the first flange 30 are welded to the inner shell 10 and the outer shell 20, respectively; the radial inner end and the radial outer end of the second flange 40 are welded to the inner shell 10 and the outer shell 20, respectively; the mounting panel 51 is provided with screw through holes 514 arranged along the first direction X, so that the mounting screws pass through the screw through holes 514 and fasten the mounting panel 51 to the first flange 30.

[0086] That is, this embodiment specifically provides a possible assembly method for an air-cooled camera, and you can refer back to Figure 1b, wherein the first flange 30 and the second flange 40 can be welded to the two ends of the inner shell 10 along the first direction X, that is, the radial inner ends of the two flanges are welded to the inner shell 10. In addition, the diverter plate 60 can be welded to the position between the two flanges of the inner shell 10; then, after the outer shell 20 is put on, the radial outer ends of the two flanges are welded to the outer shell 20 from both ends; wherein the diverter plate 60 can be welded to the inner shell 10 only through the radial inner end.

[0087] As for the installation of the front cover assembly 50, in combination with Figures 6 and 12, a screw through hole 514 can be set on the installation panel 51 of the front cover assembly 50, and the screw through hole 514 passes through the installation panel 51 along the first direction X; in this way, the front cover assembly 50 can be first plugged into the connecting portion 21 of the outer shell 20. At this time, it can be understood that the installation panel 51 of the front cover assembly 50 axially abuts against the first flange 30, and the insertion portion 52 of the front cover assembly 50 circumferentially abuts against the connecting portion 21; then, the installation panel 51 is fastened to the first flange 30 by installing screws, and the assembly of the front cover assembly 50 can be completed.

[0088] In one possible embodiment, as shown in Figure 13, the air-cooled camera also includes a lens assembly 91, a circuit board assembly 92 and a heat sink 93 located inside the inner shell 10; wherein the lens assembly 91 is installed on the side of the mounting panel 51 facing the first flange 30; the heat sink 93 extends along the first direction X and is fixedly installed on the inner side of the inner shell 10, and the heat sink 93 is used to support the circuit board assembly 92; the rear cover assembly 94 is fixedly installed on the outer end of the second flange 40, and the rear cover assembly 94 is used to close the end of the outer shell 20.

[0089] That is, in combination with Figures 12 and 13, the lens assembly 91 can be installed on the side of the mounting panel 51 facing the first flange 30, and then, a heat sink 93 can be welded inside the inner shell 10, for example, and heat conduction between the heat sink 93 and the inner shell 10 can be ensured. The heat sink 93 is in the shape of a flat plate extending along the first direction X, and the heat sink 93 can specifically carry the circuit board assembly 92; in this way, the heat generated by the electronic components on the circuit board assembly 92 is conducted to the inner shell 10 through the heat sink 93, and then conducted to the cooling gas, thereby achieving heat dissipation of the electronic components.

[0090] As for the tail of the air-cooled camera, similar to the front cover assembly 50 fastened to the first flange 30, the rear cover assembly 94 can be fastened and installed on the outer end of the second flange 40; wherein, a wire threading tube 95 can be set in the middle position of the rear cover assembly 94, and the wire threading tube 95 passes through the interior of the inner shell 10 to realize the installation of cables.

[0091] In addition, it can be understood that, in conjunction with FIG. 3 and FIG. 6 , positioning columns 515 and positioning holes 32 may be respectively provided between the mounting panel 51 of the front cover assembly 50 and the first flange 30 to achieve positioning installation.

[0092] In addition, regarding the dimensions of the above-mentioned components of the air-cooled camera, in a specific product example, the diameter of the air inlet hole 41 can be 15.5 mm, the distance between the center of the air inlet hole 41 and the center of the inner shell can be 56.7 mm, along the first direction X, the distance between the diverter plate 60 and the inner side of the second flange 40 is 40 mm, the diameter of the diverter hole 61 is 13 mm, and the center distance between the two diverter holes 61 on both sides is 45 mm. The air outlet hole 31 is centered on the first flange 30.

The length and width of the air outlet groove 55 are 74 mm × 4.3 mm. The diameter of the through air hole 513 is 10 mm, and the distance between the center of the through air hole 513 and the center of the installation panel 51 can be 58 mm. Among the four guide ribs 76, the spacing between the two low-position guide ribs 761 is 6 mm, and the spacing between the two high-position guide ribs 762 is 20 mm. The maximum fillet radius of the fillet 75 is 8.6 mm.

[0093] A second aspect of an embodiment of the present application provides a camera, comprising an inner housing 10 and an outer housing 20 extending along a first direction X and coaxially arranged, a first flange 30 and a second flange 40 disposed between the inner housing 10 and the outer housing 20, and a front cover assembly 50 plugged into the outer housing 20. The outer housing 20 is disposed externally of the inner housing 10, with both the inner housing 10 and the outer housing 20 being open at both ends along the first direction X. The first flange 30 and the second flange 40 are respectively located at both ends of the inner housing 10 along the first direction X, and the first flange 30 and the second flange 40 respectively seal the annular space between the inner housing 10 and the outer housing 20, thereby forming an annular first accommodating space 100 between the inner housing 10 and the outer housing 20. The front cover assembly 50 is plugged into the connection portion 21 of the housing 20, which protrudes axially from the first flange 30. The front cover assembly 50 includes a mounting panel 51 extending perpendicularly to the first direction X. The mounting panel 51 is provided with at least a photographing window 511. An insertion portion 52 extends from the circumferential end of the mounting panel 51, facing away from the first flange 30, along the first direction X. The portion of the insertion portion 52 located above the photographing window 511 is radially inwardly recessed to form a receiving groove 53. The bottom plate 54 of the receiving groove 53 is provided with an air outlet groove 55. The bottom plate 54 and the air outlet groove 55 extend along a second direction Y, which is the width of the photographing window 511. Cooling gas can pass through the receiving groove 53 and the air outlet groove 55 to purge the photographing window 511.

[0094] The camera provided in the embodiments of the present application has two implementations. One of them can be an air-cooled camera as described above, which uses cooling gas to enter the first accommodating space 100 to cool the camera's internal electronic components. The cooling gas in the first accommodating space 100 can also be used to purge the shooting window 511. Specifically, the cooling gas in the first accommodating space 100 passes through the air outlet hole 31 of the first flange 30, enters the through-hole 513, enters the accommodating groove 53, and then passes through the air outlet slot 55 to purge the shooting window 511. Another implementation can be a water-cooled camera, which uses a water-cooling medium to enter the first accommodating space 100 to cool the camera's internal electronic components. The gas used to purge the shooting window 511 comes directly from the external environment. Specifically, a separate air inlet 22 for cooling gas is provided on the housing 20. The cooling gas from the outside enters the accommodating groove 53 through the air inlet 22 and then passes through the air outlet slot 55 to purge the shooting window 511.

[0095] In both camera types, the annular space between the inner housing 10 and the outer housing 20 is sealed with a first flange 30 and a second flange 40 at each end. This creates a first accommodating space 100 between the inner housing 10 and the outer housing 20, allowing the electronic components within the inner housing 10 to be cooled using a water-cooling medium or cooling gas. The front cover assembly 50 is plugged into the connection portion 21 of the outer housing 20. The insertion portion 52 of the front cover assembly 50 has a radially inward recess 53. Cooling gas is directed through an air outlet slot 55 on the bottom plate of the recess 53 to purge the camera window 511 on the mounting panel 51. This simple structure allows for easy installation and assembly. Furthermore, the bottom plate 54 and the air outlet slots 55 thereon extend along the width of the camera, allowing the cooling gas (also the purge medium) to be concentrated above the camera window 511 and purge it, preventing negative pressure in the camera window 511 and achieving effective cooling and dust removal.

[0096] The following will provide a detailed introduction using a water-cooled camera as an example. Unlike an air-cooled camera, the cooling gas used by a water-cooled camera to purge the shooting window 511 does not come from the first accommodating space 100, but directly from the external environment. Specifically, please refer to Figures 14, 15, 16 and 17. The housing 20 is provided with an air inlet 22 connected to the accommodating groove 53. The cooling gas flows from the air inlet 22 through the accommodating groove 53 and purges the shooting window 511 through the air outlet groove 55.

[0097] In this embodiment, cooling gas enters from the air inlet 22 through the accommodating groove 53 and the air outlet groove 55 above the shooting window 511 to purge the shooting window 511. The structure is simple, the purge area is more concentrated, and it is not easy to have negative pressure on the surface of the shooting window 511, so the cooling and dust removal effects are better.

[0098] 17 and 18 , along the first direction X, the second flange 40 is provided with a water inlet 42 and a water outlet 43. Along the third direction Z, the water inlet 42 is located below the water outlet 43, and the third direction is perpendicular to the first and second directions.

[0099] Providing the water inlet 42 and water outlet 43 along the first direction X on the second flange 40 can reduce the installation cross-sectional area of ​​the housing 20, facilitate customer assembly, and effectively reduce the difficulty of customizing the housing 20. Furthermore, locating the water inlet 42 below the water outlet 43 shortens the distance the cooling water travels to enter the lower half of the first accommodating space 100. After the cooling water fills the lower half of the first accommodating space 100, the water level slowly rises until it fills the entire first accommodating space 100 before flowing out through the water outlet 43, improving cooling efficiency.

[0100] With reference to Figures 19, 20, 21, and 22, two partitions 300 are provided within the first accommodating space 100. The partitions 300 extend along a first direction X, dividing the first accommodating space 100 into a first portion 101 and a second portion 102. The first portion 101 is located below the partitions 300 along a third direction. The widthwise ends of the partitions 300 are fixedly connected to the inner walls of the outer shell 20 and the inner shell 10, respectively. A flow channel 103 is defined between the partitions 300 and the first flange 30, connecting the first portion 101 and the second portion 102. In the annular cross-section of the second flange 40, the water inlet 42 is located in the arcuate cross-section below the partitions 300, while the water outlet 43 is located in the arcuate cross-section above the partitions 300.

[0101] Due to the action of the two partitions 300 in the first accommodating space 100, after the cooling water enters the first accommodating space 100, it first gathers in the first part 101 of the first accommodating space 100. After the cooling water fills the first part 101, it enters the second part 102 from the flow channel 103 between the partition 300 and the first flange 30, and then flows out from the water outlet 43, so that the cooling water can form a complete circulation inside the first accommodating space 100, thereby improving the cooling efficiency.

[0102] It should be noted that the structural design of the outer shell 20 and the inner shell 10 of the aforementioned air-cooled camera, that is, the outer shell 20 is a cylindrical sleeve extending along the first direction X, and the inner shell 10 includes a first flat plate 11 and a second flat plate 12 arranged relatively, and other specific structures are also applicable to water-cooled cameras. Specifically, please refer to Figures 18 and 22, and no further details will be given here.

[0103] The bottom plate 54 of the water-cooled camera is also perpendicular to the mounting panel 51 , and the air outlet groove 55 formed on the bottom plate 54 is also the same as that described for the air-cooled camera. Please refer back to Figures 8-10 and no further details will be given here.

[0104] In addition, regarding the dimensions of the aforementioned components of the water-cooled camera, in some specific product examples, the inner diameters of the water inlet 42 and water outlet 43 are designed to be 14-16 mm, and can be 15.5 mm, for example. They are located at the rear of the housing 20 and welded to the second flange 40, symmetrically distributed vertically. The distance between the centers of the water inlet 42 and water outlet 43 is 113-114 mm. The diameter of the air inlet 22 can be 8-10 mm, and can be 9 mm, for example. The distance between the centerline of the air inlet 22 and the front face of the first flange 30 is set to 23 mm-24 mm, and can be 24.2 mm, for example. As shown in Figure 21, a flow channel 103 is provided between the partition 300 and the first flange 30. The width of the flow channel can be 9 mm-11 mm, and can be 10 mm, for example, to circulate cooling water.

[0105] It should be noted that, as shown in Figures 23, 24, and 25, the front cover assembly 50 of the water-cooled camera has the same structure as the front cover assembly 50 of the air-cooled camera. The side away from the first flange 30 includes a shooting window 511, a fill light window 512 located below the shooting window 511, and an air outlet groove 55 located above the shooting window 511. Unlike the air-cooled camera, the air guide plug 70 is not provided within the accommodating groove 53. The installation of the front cover assembly 50 of the water-cooled camera is similar to that of the air-cooled camera and will not be further described here. The lens assembly 91, circuit board assembly 92, and heat sink 93 within the inner housing 10 of the water-cooled camera are the same as those of the air-cooled camera and will not be further described here.
