[0032] In order to make the above objectives, features and advantages of the present application more apparent, more comprehensible, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. First, it should be noted that in the present specification, the orientation terms such as up, down, left, right, front, back, inner, outer, top, bottom, etc. mentioned or possibly mentioned are defined with respect to the structure shown in the drawings, and are relative concepts, so they can change accordingly according to different positions, different use states. Therefore, these or other orientation terms should not be interpreted as restrictive terms.

[0033] In the present application, unless otherwise explicitly specified and limited, the terms such as "fixed" should be understood in a broad sense, for example, "fixed" can be fixedly connected, or can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] Figure 1The structure of the electronic control device according to the present application is shown. The electronic control device 100 is composed of a base 110, a printed circuit board 120, and a cover 130, thus forming a sandwich structure similar to a "sandwich". It should be noted that the base 110 is made of metal, such as aluminum alloy. The printed circuit board 120 is placed on the base 110 and is provided with electronic components 121, such as connectors for signal transmission, etc. The cover 130 is made of metal, such as aluminum casting, and is located above the printed circuit board 120. The cover 130 is fixed to the base 110 by a detachable manner, for example, by bolts 140, for clamping the printed circuit board 120 between the base 110 and the cover 130. In addition, the cover 130 is provided with a plurality of fins 132 for heat dissipation, so as to quickly dissipate the heat of the electronic components to the air.

[0035] With reference to Figures 1 to 3 At the edge of the base 110 close to the electronic components 121, a bending structure 111 for shielding signals is provided, which includes a bending edge 111a extending towards the cover 130, wherein the height of the bending edge 111a in the direction perpendicular to the plane of the base 110 is not less than, for example, exceeds the height of the printed circuit board 120, so as to shield the printed circuit board 120 between the base 110 and the cover 130, and prevent signals from escaping from the gap between the base 110 and the cover 130.

[0036] Generally, the base 110 has a substantially rectangular shape, and the bending structure 111 can be provided on the lengthwise edge of the base 110 and / or on the widthwise edge of the base 110 according to requirements (see Figure 4 and Figure 5 ), and the number, size, and shape of the bending structure 111 are not specifically limited here. In addition, for the purpose of facilitating manufacturing, the bending structure 111 can be integrally formed with the base 110 by stamping. The bending angle of the bending structure 111 (i.e. the included angle between the bending edge 111a and the plane of the base 110) is between 90-120°.

[0037] In other optional embodiments in combination with the above embodiments, the electronic components 121 include connectors, and the base 110 can be further provided with a first boss structure 112 and a second boss structure 113, the first boss structure 112 at least partially covers the connectors, for shielding the high-speed signals of the connectors, such as Figure 6 and Figure 7Further, the base 110 can completely cover the printed circuit board 120. Specifically, the base 110 can prevent signal leakage from the lower space of the electronic device 121, while the cover 130 can prevent signal leakage from the upper space of the electronic device 121, thereby shielding the high-speed signal emitted from the electronic device 121 in various directions. Further, the first boss structure 112 and / or the second boss structure 113 can be formed, for example, by stamping.

[0038] As can be easily understood by those skilled in the art, the cover 130 is provided with a recess 131 for accommodating the folded edge 111a, as shown in Figure 6 and Figure 7 as shown.

[0039] In addition, the present application also provides a reversing image system provided with the electronic control device 100 described above. The technical improvements and advantages of the reversing image system are the same as those of the electronic control device 100, and therefore the reversing image system will not be described in detail.

[0040] In addition, the present application also provides a vehicle provided with the reversing image system described above. The vehicle can be a private car, a taxi, a bus, a minibus, a large bus, or various vehicles. The technical improvements and advantages of the vehicle are the same as those of the reversing image system, and therefore the vehicle will not be described in detail.

[0041] In summary, the electronic control device according to the present application can not only effectively prevent signal leakage from the gap between the cover and the base by providing a folded edge structure at the edge of the base, but also save production costs and further improve the overall quality of the electronic control device.
