It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0041] The heat dissipation structure of the automotive front-view integrated device provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0042] like Figures 1 to 5 As shown, an embodiment of the present application provides a heat dissipation structure of a front-view integrated device for an automobile, including a front cover 110, a rear cover 120, a visual module 210, and a control board 220. The front cover 110 and the rear cover 120 are fixedly connected and interlocked to form an installation cavity. The control board 220 is fixedly arranged in the installation cavity. The visual module 210 is connected to the control board 220 and is used to obtain visual information on the outside of the front cover 110 and the rear cover 120.

[0043] A heat-conducting adhesive 330 connected to the rear cover 120 is disposed on the end surface of the control board 220 away from the front cover 110, and an air cooling unit is fixedly disposed on the end surface of the rear cover 120 away from the front cover 110. A cover plate 130 fixedly connected to the rear cover 120 is disposed on the side of the air cooling unit away from the rear cover 120.

[0044] In an embodiment of the present application, the above-mentioned heat dissipation structure of the automotive front-view integrated machine is adopted, and the heat of the control board 220 is transferred to the rear cover 120 through the thermal conductive adhesive 330, and then the surface of the rear cover 120 is actively dissipated through the air cooling unit, thereby ensuring the working stability of the front-view integrated machine.

[0045] In a preferred embodiment, Figure 3 , Figure 4 As shown, an embedding groove 121 for embedding with the air cooling unit is provided on the end surface of the rear cover 120 away from the front cover 110.

[0046] It is understandable that, since the embedding groove 121 has a certain depth, when the air cooling unit is installed in the embedding groove 121, the overall thickness of the front viewing integrated machine can be reduced, thereby facilitating the installation of the front viewing integrated machine.

[0047] In a preferred embodiment, Figures 1 to 5 As shown, the air cooling unit is specifically configured as an axial flow fan 410 fixedly connected to the end surface of the rear cover 120 away from the front cover 110, and the end of the axial flow fan 410 close to the rear cover 120 is an air suction end, and the end away from the rear cover 120 is an air exhaust end;

[0048] An air outlet 131 is formed on the cover plate 130 at a position corresponding to the exhaust end of the axial flow fan 410 , and the axial flow fan 410 can discharge the heat on the surface of the rear cover 120 through the air outlet 131 .

[0049] In a preferred embodiment, Figure 2 , Figure 3 , Figure 5 As shown, a fin assembly is fixedly provided on the end surface of the rear cover 120 away from the front cover 110 .

[0050] It is understandable that the fin assembly can conduct the heat on the surface of the rear cover 120, thereby increasing the overall heat dissipation area of ​​the front-view integrated machine and further improving the heat dissipation effect.

[0051] In a preferred embodiment, Figure 2 , Figure 3 , Figure 5 As shown, the fin assembly includes a first heat dissipation fin 310 and a second heat dissipation fin 320 which are fixedly disposed on an end surface of the rear cover 120 away from the front cover 110 and are perpendicular to each other.

[0052] A plurality of first heat dissipation fins 310 are provided on the rear cover 120 in a linear array along the length direction of the second heat dissipation fins 320 , and a plurality of second heat dissipation fins 320 are provided on the rear cover 120 in a linear array along the length direction of the first heat dissipation fins 310 .

[0053] In a preferred embodiment, Figure 1 , Figure 2 , Figure 5 As shown, the cover plate 130 is fixedly disposed on the end surface of the first heat dissipation fin 310 away from the rear cover 120 .

[0054] It is understandable that the fixed connection form of the cover 130 is not limited to the above-mentioned one. For example, the cover 130 can also be fixedly set on the second heat dissipation fin 320, or directly fixedly installed on the back cover 120. As long as it can protect the air cooling unit, it will not be elaborated here.

[0055] In a preferred embodiment, Figure 2 , Figure 3 , Figure 5 As shown, the first heat dissipation fins 310 and the second heat dissipation fins 320 do not intersect each other, and the extension lines of the plurality of second heat dissipation fins 320 along the length direction intersect with the first heat dissipation fins 310 .

[0056] The air cooling unit is located at a position corresponding to one end of the first heat dissipation fins 310 , and corresponds to a position of the plurality of second heat dissipation fins 320 close to one end of the first heat dissipation fins 310 .

[0057] In a preferred embodiment, Figure 5 As shown, the air cooling unit further includes a radial flow fan 420 fixedly disposed at one end of the axial flow fan 410 away from the rear cover 120;

[0058] The exhaust end of the axial flow fan 410 corresponds to the air inlet end of the radial flow fan 420 , and the radial flow fan 420 can disperse the airflow output from the exhaust end of the axial flow fan 410 in the radial direction.

[0059] In an embodiment of the present application, the above-mentioned automotive front-view integrated device heat dissipation structure is adopted. When the radial fan 420 discharges air radially, the air can flow along the array gaps of the first heat dissipation fins 310 and the second heat dissipation fins 320, thereby taking away the heat on the surfaces of the first heat dissipation fins 310 and the second heat dissipation fins 320, thereby improving the heat exchange efficiency of the fin assembly and ensuring the overall heat dissipation effect of the device.

[0060] It can be understood that the overall heat dissipation intensity of the device can be improved through the cooperation of the axial fan 410 and the radial fan 420. At the same time, the axial fan 410 can also be omitted, that is, the air inlet end of the radial fan 420 directly corresponds to the position 120. At this time, it can also play a role in blowing air into the array gaps of the first cooling fins 310 and the second cooling fins 320, but the heat dissipation intensity will be reduced. The specific setting form is formulated based on actual needs and will not be elaborated here.

[0061] In a preferred embodiment, Figure 5As shown, a plurality of through holes 311 are arranged in an array along the length direction on the first heat dissipation fin 310 which is closest to the second heat dissipation fin 320 , and the plurality of through holes 311 correspond to the array gap positions of the second heat dissipation fin 320 , respectively.

[0062] It can be understood that when the radial fan 420 is working and drives the air to flow along the array gaps of the first heat sink fins 310, the array gaps on the side of the first heat sink fins 310 closest to the second heat sink fins 320 can output airflow to the array gaps of the second heat sink fins 320 through the through holes 311, thereby increasing the air cooling path of the fin assembly and improving the heat dissipation effect of the device.

[0063] In a preferred embodiment, Figure 4 As shown, a heat-conducting protrusion 123 corresponding to the position of the heat-conducting adhesive 330 is fixedly provided on the end surface of the rear cover 120 close to the front cover 110 .

[0064] It is understandable that when the front cover 110 and the rear cover 120 are fixedly connected, the heat-conducting protrusion 123 contacts the heat-conducting adhesive 330 at the corresponding position, thereby achieving heat conduction between the two.

[0065] In a preferred embodiment, Figure 3 , Figure 4 As shown, a positioning protrusion 112 plugged into the control board 220 is fixedly provided at an edge of the front cover 110 close to the rear cover 120 , and a positioning groove 122 capable of engaging with the positioning protrusion 112 is provided at a position corresponding to the positioning protrusion 112 on the rear cover 120 .

[0066] It is understandable that, through the engagement between the positioning protrusion 112 and the positioning groove 122 , the connection strength between the front cover 110 and the rear cover 120 can be improved, and the installation guidance between the two can be facilitated.

[0067] In a preferred embodiment, Figure 3 , Figure 4 As shown, a plurality of positioning protrusions 112 are provided at an edge of the front cover 110 close to the rear cover 120 .

[0068] In a preferred embodiment, Figures 1 to 5 As shown, a limiting plate 140 which can be buckled with the rear cover 120 is fixedly provided on the front cover 110 .

[0069] The limiting plate 140 is specifically configured as an L-shaped plate. When the front cover 110 and the rear cover 120 are connected, the limiting plate 140 can contact the rear cover 120 and limit the displacement of the rear cover 120 away from the front cover 110 .

[0070] In a preferred embodiment, Figures 1 to 5As shown, the front cover 110 and the rear cover 120 are fixedly connected by bolts.

[0071] In a preferred embodiment, Figure 1 As shown, a plurality of heat dissipation convex plates 111 in a linear array are fixedly provided on an end surface of the front cover 110 away from the rear cover 120 .

[0072] It is understandable that the installation cavity inside the front cover 110 and the rear cover 120 can be further heat-conducted by the multiple heat dissipation convex plates 111 .

[0073] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes 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 sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0074] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
