[0009] In the rear view camera device as above, each side wall of the second air duct section is parallel to the first direction.

[0010] In the rear view camera device as above, the second air duct segment has an extension length L along the first direction, and the extension length L has a range: L≥5 mm.

[0027] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0028] like Figures 1 to 6 As shown, an embodiment of the present application provides a rear view camera device, which includes: a protective shell 10, including a windward wall 11 and a leeward wall 12 connected to each other, the windward wall 11 is a streamlined structure along a first direction X, and the leeward wall 12 is a plate-like structure arranged at a preset angle to the first direction X; a camera structure 20, arranged in the protective shell 10, the camera structure 20 includes a camera 21, and the camera 21 passes through the leeward wall 12; an air duct structure 30, which is an internally hollow shell structure, the air duct structure 30 extends along the first direction X and is arranged in the protective shell 10, and the two ends of the air duct structure 30 are respectively an air inlet 31 and an air outlet 32, the air inlet 31 passes through the windward wall 11, and the air outlet 32 ​​passes through the leeward wall 12, and in the third direction Z, the air outlet 32 ​​is arranged below the camera 21.

[0029] In specific implementation, the rearview camera device of the embodiment of the present application is installed on the top of the vehicle, including a protective shell 10, a camera structure 20 and an air duct structure 30. The protective shell 10 includes a windward wall 11 and a leeward wall 12. The windward wall 11 is a streamlined structure along the first direction X, and is arranged toward the front direction of the vehicle. During the driving of the vehicle, the windward wall 11 of the streamlined structure has a small resistance. The leeward wall 12 is a plate-like structure arranged at a preset angle to the first direction X, and is arranged toward the rear direction of the vehicle. The camera 21 of the camera structure 20 passes through the leeward wall 12 and can shoot in the direction of the rear of the vehicle, thereby realizing the rearview camera function of the rearview camera device, and the wind blowing from the front direction of the vehicle and the debris in the wind will not contact the camera 21, and will not affect the camera quality.

[0030] The air duct structure 30 is an internal hollow shell structure extending along the first direction X, and its two ends are respectively an air inlet 31 and an air outlet 32. The air inlet 31 penetrates the windward wall 11 set toward the front direction of the vehicle. When the vehicle is driving, the air flows toward the windward wall 11, enters the air duct structure 30 through the air inlet 31, and reaches the air outlet 32 ​​through the space inside the air duct structure 30. Since the air outlet 32 ​​penetrates the leeward wall 12 set toward the rear direction of the vehicle, and the air outlet 32 ​​is arranged below the camera 21, the air outlet 32 ​​can continuously blow out air with a higher flow rate below the camera 21 when the vehicle is driving, thereby isolating the airflow rolled up at the rear of the vehicle, so that the exhaust gas of the vehicle cannot reach the camera 21 and pollute the camera 21, so that the imaging of the rearview camera device is clear.

[0031] Specifically, the protective shell 10 is arranged in a shark fin shape as a whole. Along the direction from the front to the rear of the vehicle, the height of the windward wall 11 in the third direction Z gradually increases, and the outer surface still has a streamlined structure. The leeward wall 12 is perpendicular to the first direction X as a whole and is connected to the part of the windward wall 11 close to the rear of the vehicle, so that the camera 21 can be installed facing the rear of the vehicle, so that the collected image has a viewing angle that is convenient for the driver to observe. The windward wall 11, the leeward wall 12 and the top of the vehicle together enclose an installation space for installing the camera structure 20 and the air duct structure 30.

[0032] Moreover, if Figure 4 As shown, the protective shell 10 also has a disassembly installation portion 13, and the disassembly installation portion 13 is arranged around the edge of the windward wall 11 as a whole, and has a plurality of clips. The protective shell 10 is detachably installed on the top of the vehicle through the plurality of clips. When the camera structure 20 is damaged, the protective shell 10 can be disassembled to repair or replace the camera structure 20.

[0033] Optionally, the vehicle's antenna can be installed inside the protective shell 10 at the same time. The protective shell 10 can protect the antenna and the camera structure 20 at the same time, and saves installation space, without the need to set a separate antenna on the roof.

[0034] like Figure 1 As shown, the rear view camera device of the embodiment of the present application, wherein the air outlet 32 ​​is a strip structure extending along the second direction Y, the air outlet 32 ​​has a first width D1 in the second direction Y, the camera 21 has a second width D2 in the second direction Y, and the first width D1 and the second width D2 have a relationship: D1>D2.

[0035] It should be noted that the first direction X, the second direction Y and the third direction Z are arranged perpendicular to each other. When the rear view camera device is installed on a vehicle, the first direction X is the driving direction of the vehicle, the second direction Y is the width direction of the vehicle, and the third direction Z is the height direction of the vehicle.

[0036] In specific implementation, the air outlet 32 ​​is a strip structure extending along the second direction Y. When air is discharged from the air outlet 32, an air wall extending along the second direction Y can be formed. Since the air duct structure 30 extends along the first direction X as a whole, the plane where the air wall is located is perpendicular to the third direction Z. When the vehicle exhaust gas flows upward along the third direction Z, it can be blocked by the air wall; and the first width D1 of the air outlet 32 ​​is greater than the second width D2 of the camera 21, so that the air wall discharged from the air outlet 32 ​​can cover the camera 21 as a whole in the second direction Y, thereby preventing the vehicle exhaust gas from flowing upward from both sides of the air wall to the camera 21 and causing pollution to the camera 21.

[0037] Optionally, multiple cameras 21 can be set. In this case, the second width D2 of the camera 21 is the overall width of the multiple cameras 21. Taking two cameras 21 spaced apart along the second direction Y as an example, the second width D2 is the sum of the widths of the two cameras 21 and the spacing between the two cameras 21. In this case, the first width D1 is still greater than the second width D2. Such a setting can ensure that the multiple cameras 21 will not be polluted by vehicle exhaust.

[0038] like Figure 1 As shown, in the rear view camera device of the embodiment of the present application, in the setting plane of the air outlet 32, the maximum width of the protective shell 10 in the second direction Y is the third width D3, and the first width D1 and the third width D3 have a relationship: D1>70%D3.

[0039] In specific implementation, the first width D1 of the air outlet 32 ​​is more than 70% of the maximum width of the protective shell 10, that is, the third width D3, which can ensure that the width is sufficient. After the vehicle exhaust passes through the two sides of the air wall formed by the air outlet 32, even if there is a phenomenon of inward contraction, only a small part of the exhaust gas can reach the camera 21, and will not cause serious pollution to the camera 21, further ensuring the camera quality of the rearview camera device.

[0040] like Figure 3 As shown, a rear view camera device of an embodiment of the present application, wherein the air duct structure 30 includes a first air duct section 33 and a second air duct section 34 connected to each other, the ends of the first air duct section 33 and the second air duct section 34 are connected, the air inlet 31 is arranged at the end of the first air duct section 33 close to the windward wall 11, the air outlet 32 ​​is arranged at the end of the second air duct section 34 close to the leeward wall 12, and the cross-sectional area of ​​the second air duct section 34 perpendicular to the first direction X is less than or equal to the minimum cross-sectional area of ​​the first air duct section 33 perpendicular to the first direction X.

[0041] During specific implementation, the cross-sectional area of ​​the second air duct section 34 is smaller than the minimum cross-sectional area of ​​the first air duct section 33. When the air flows from the first air duct section 33 to the second air duct section 34, the air flow rate will increase due to the reduction in the cross-sectional area. When the air flows out from the air outlet 32, a more stable air wall can be formed, which has a better barrier effect on the exhaust gas, thereby preventing the exhaust gas from polluting the camera 21.

[0042] like Figure 3 As shown, in the rear view camera device of the embodiment of the present application, each side wall of the second air duct section 34 is parallel to the first direction X.

[0043] In specific implementation, the second air duct section 34 is in the shape of a rectangular parallelepiped as a whole, and its cross-sectional areas at all locations perpendicular to the first direction X are equal. When the air passes through the second air duct section 34, the speed and volume are relatively stable. After passing through the second air duct section 34 and flowing out from the air outlet 32, a stable air wall with constant direction is formed. The plane where the air wall is located is perpendicular to the third direction Z and will not tilt, thereby avoiding the exhaust gas from being rolled to the camera 21 due to the tilt of the air wall, so that the exhaust gas can be stably isolated.

[0044] like Figure 3 As shown, in the rear view camera device of the embodiment of the present application, the second air duct segment 34 has an extension length L along the first direction X, and the extension length L has a range: L≥5mm.

[0045] In specific implementation, the minimum extension length L of the second air duct section 34 is 5 mm, so that the air has a forming distance to form a stable and constant-direction air wall in the process of passing through the second air duct section 34 to reach the air outlet 32. Because the direction of the air is also inclined downward when passing through the inclined first air duct section 33, a parallel air wall can be formed only after passing through the second air duct section 34 which is arranged in parallel and has a length of at least 5 mm, thereby stably isolating the exhaust gas.

[0046] like Figure 3 As shown, in the rear view camera device of the embodiment of the present application, the cross-sectional area of ​​the first air duct section 33 shows a gradually shrinking trend along the direction from the air inlet 31 to the air outlet 32 ​​.

[0047] During specific implementation, when the air passes through the first air duct section 33 with a gradually shrinking cross-sectional area, the air can be squeezed by the inner surface of the first air duct section 33, and the flow velocity gradually increases, eventually forming an air wall with a faster flow velocity to effectively isolate the exhaust gas; moreover, the cross-sectional area of ​​the first air duct section 33 tends to shrink gradually, and when the air passes through the first air duct section 33, the first air duct section 33 will not experience a sudden change in cross-sectional area, so that the flow velocity of the finally formed air wall is stable, and the exhaust gas is prevented from passing through the unstable part of the air wall, thereby achieving stable isolation of the exhaust gas by the air wall.

[0048] like Figure 3 As shown, in the rear view camera device of the embodiment of the present application, the air inlet 31 has a first area S1, the air outlet 32 ​​has a second area S2, and the first area S1 and the second area S2 have a relationship: S1>2S2.

[0049] In specific implementation, the first area S1 is larger than twice the second area S2, which ensures that the area of ​​the air inlet 31 is sufficient, and the amount of air passing through the air inlet 31 is at least twice the amount of air passing through the air outlet 32. Therefore, the air flow rate through the air outlet 32 ​​is at least twice the air flow rate through the air inlet 31. The air discharged at the air outlet 32 ​​can have a sufficient flow rate, thereby forming a stable air wall to effectively isolate the exhaust gas.

[0050] like Figure 3 As shown, in the rear view camera device of the embodiment of the present application, the air duct structure 30 includes a plurality of connection parts 35 arranged at intervals, and the air duct structure 30 is detachably arranged inside the protective shell 10 through the connection parts 35.

[0051] During specific implementation, the air duct structure 30 can be disassembled through the connecting portion 35 , and in the event of damage, it can be removed from the protective shell 10 for repair or replacement, thereby improving the convenience of repair.

[0052] Specifically, the connection portion 35 is a bolt connection structure, and the air duct structure 30 is bolted to the rear wing of the vehicle through the connection portion 35. The bolt connection method is easy to disassemble and is convenient.

[0053] Optionally, the connection portion 35 may be a detachable connection structure such as a buckle.

[0054] like Figure 5 and Figure 6 As shown, the embodiment of the present application further provides a vehicle, wherein the vehicle includes the above-mentioned rear-view camera device, and the vehicle also includes a rear wing, and the protective housing 10 and the air duct structure 30 of the rear-view camera device are both detachably connected to the rear wing. The rear-view camera device is arranged at the rear wing of the vehicle, which can ensure the viewing angle of the camera, and the rear-view camera device in the embodiment of the present application can effectively isolate the upward airflow at the rear wing, so that the overall image of the rear-view camera device of the streaming media is clear.

[0055] The vehicle of the embodiment of the present application includes a rear-view camera device, which is installed on the rear wing on the top of the vehicle, including a protective shell 10, a camera structure 20 and an air duct structure 30. The protective shell 10 includes a windward wall 11 and a leeward wall 12. The windward wall 11 is a streamlined structure along a first direction X, and is arranged toward the front direction of the vehicle. The leeward wall 12 is a plate-like structure arranged at a preset angle to the first direction X, and is arranged toward the rear direction of the vehicle. The camera 21 of the camera structure 20 passes through the leeward wall 12 and can shoot in the direction of the rear of the vehicle, thereby realizing the rear-view camera function of the rear-view camera device.

[0056] The air duct structure 30 is an internal hollow shell structure extending along the first direction X, and its two ends are respectively an air inlet 31 and an air outlet 32. The air inlet 31 penetrates the windward wall 11 set toward the front direction of the vehicle. When the vehicle is driving, the air flows toward the windward wall 11, enters the air duct structure 30 through the air inlet 31, and reaches the air outlet 32 ​​through the space inside the air duct structure 30. Since the air outlet 32 ​​penetrates the leeward wall 12 set toward the rear direction of the vehicle, and the air outlet 32 ​​is arranged below the camera 21, the air outlet 32 ​​can continuously blow out air with a higher flow rate below the camera 21 when the vehicle is driving, thereby isolating the airflow rolled up at the rear of the vehicle, so that the exhaust gas of the vehicle cannot reach the camera 21 and pollute the camera 21, so that the imaging of the rearview camera device is clear.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0058] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here.
