[0043] Prior to this application, the vehicle radio was integrated into the intelligent domain controller. Currently, the shielding structure of the radio (receiver chip) on the intelligent domain controller is poor, which makes the playback signal easily interfered with, causing problems such as noise, interruption, and unsmooth playback.

[0044] In view of this, the first aspect of this application provides an intelligent domain controller, thereby solving the problem that the shielding structure of the radio (receiver chip) on existing intelligent domain controllers is poor, resulting in interference with the playback signal, causing noise, interruptions, and uneven playback. See below for reference. Figures 1 to 11 This application describes a smart domain controller according to some embodiments.

[0045] like Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the intelligent domain controller of this application includes a circuit board 600, a radio chip 800, a shielding cover 300, an elastic element 400, and a first housing 100 (lower housing). The radio chip 800 is disposed on the surface (lower surface) of the circuit board 600. The shielding cover 300 is connected to the circuit board 600 and covers the radio chip 800. An elastic element 400 is disposed on the side of the shielding cover 300 facing away from the circuit board 600, and the elastic element 400 is press-fitted between the shielding cover 300 and the first housing 100.

[0046] In other words, this application achieves electromagnetic signal shielding through the shielding cover 300, thereby improving the audio playback quality of the radio reception. To prevent the shielding cover 300 from shifting internally, after the shielding cover 300 and the first housing 100 are installed, the elastic element 400 is pressed between the shielding cover 300 and the first housing 100, with a certain interference fit with the first housing 100, which can effectively press the shielding cover 300 tightly to prevent shifting. The electromagnetic shielding cover 300 design of this application improves the radio reception quality. The addition of the elastic element 400 on the shielding cover 300 changes the traditional rigid connection to a flexible connection, which, while preventing shifting, also ensures that the shielding cover 300 meets the requirements in the vibration test and free drop test of the whole vehicle.

[0047] Preferably, in the embodiments of this application, such as Figure 3 As shown, the shielding cover 300 has a rectangular frame structure, including a rectangular bottom wall and four surrounding walls along the outer edge of the bottom wall, all of which are connected to the circuit board 600. Four elastic elements 400 are located on the side of the bottom wall opposite to the circuit board 600, at the four corners of the bottom wall. This arrangement, with the elastic elements 400 symmetrically distributed at the four corners, forms a rectangular support frame. The four elastic elements 400 are evenly pressed and stressed, effectively preventing the shielding cover 300 from shifting while ensuring that the shielding cover 300 meets customer requirements in vehicle vibration tests and free-fall tests.

[0048] Preferably, in the embodiments of this application, the elastic element 400 is foam.

[0049] Preferably, in the embodiments of this application, in order to facilitate the assembly of the shielding cover 300 with the first housing 100 and to prevent the shielding cover 300 from shifting, the assembly gap between the shielding cover 300 and the first housing 100 is 0.5 mm, and the thickness of the elastic member 400 is 1 mm, so that after the shielding cover 300 is installed, there is an interference fit of 0.5 mm with the first housing 100.

[0050] Preferably, in the embodiments of this application, the shielding cover 300 saves costs while ensuring electromagnetic signal shielding. The thickness of the bottom wall and the surrounding wall of the shielding cover 300 in this application is 0.3 mm.

[0051] Furthermore, in the embodiments of this application, to further facilitate the assembly of the shielding cover 300 and improve its stability, the intelligent domain controller of this application also includes at least two shielding cover clips 700, both of which are fixed to the circuit board 600, and at least two of the four enclosures are held by the shielding cover clips 700.

[0052] As an example, such as Figure 3 , Figure 6 and Figure 7 As shown, the intelligent domain controller of this application also includes a radio connector 610, which is electrically connected to the circuit board 600 and is used to connect to the vehicle's audio system. The intelligent domain controller includes three shielding clips 700, and three of the four enclosures are respectively held by the three shielding clips 700; the radio chip 800 is electrically connected to the radio connector 610 via copper wire through the circuit board 600, and the fourth of the four enclosures has a clearance hole 310 for the copper wire to pass through.

[0053] Preferably, in an embodiment of this application, the shielding clip 700 is soldered to the circuit board 600, and each shielding clip 700 includes at least two elastic arms 720, with each enclosure being held by two elastic arms 720. As an example, such as... Figure 5 As shown, each shielding clip 700 includes a main body 710 and two pairs of elastic arms 720, each pair of elastic arms 720 including two elastic arms 720, and each enclosure is clamped by the two pairs of elastic arms 720.

[0054] Additionally, in the embodiments of this application, such as Figure 4 As shown, a plurality of heat dissipation protrusions 110 are provided on the side of the first housing 100 facing the circuit board 600, and the plurality of heat dissipation protrusions 110 are in contact with the circuit board 600 through a thermally conductive structural layer. In this embodiment, the thermally conductive structural layer can be thermally conductive silicone grease to dissipate heat from the circuit board 600. In this embodiment, the first housing 100 can be integrally formed by stamping.

[0055] Additionally, in the embodiments of this application, such as Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 The intelligent domain controller also includes a second housing 200 and fastening screws 900. The second housing 200 includes a top wall and side walls surrounding the edge of the top wall. The top wall and side walls form a receiving space for mounting the circuit board 600. The side walls have openings that expose the radio connector 610. The circuit board 600 is mounted between the first housing 100 and the second housing 200 by six fastening screws 900. The six fastening screws 900 (self-tapping screws) pass sequentially through the first housing 100, the circuit board 600, and the second housing 200.

[0056] The assembly process of the intelligent domain controller in this application is as follows:

[0057] The shielding cover clips 700 are soldered to the circuit board 600 using welding technology, with three clips used. 1mm thick foam is adhered to the four right-angle positions on the front of the shielding cover 300. The shielding cover 300 is then installed onto the circuit board 600 using the shielding cover clips 700, ensuring the radio chip 800 is securely held inside the shielding cover 300. The circuit board 600 is then installed into the second housing 200, and the first housing 100 is installed and tightened with six self-tapping screws. Furthermore, to prevent the shielding cover 300 from shifting internally, the foam thickness is designed to be 1mm, resulting in a 0.5mm interference fit between the shielding cover 300 and the first housing 100 after installation. Tightening the self-tapping screws secures the shielding cover 300, preventing shifting.

[0058] In other words, this application achieves electromagnetic signal shielding through the shielding cover 300, thereby improving the audio playback quality of the radio reception. To prevent the shielding cover 300 from shifting internally, after the shielding cover 300 and the first housing 100 are installed, the elastic element 400 is pressed between the shielding cover 300 and the first housing 100, with a certain interference fit with the first housing 100, which can effectively press the shielding cover 300 tightly to prevent shifting. The electromagnetic shielding cover 300 design of this application improves the radio reception quality. The addition of the elastic element 400 on the shielding cover 300 changes the traditional rigid connection to a flexible connection, which, while preventing shifting, also ensures that the shielding cover 300 meets the requirements in the vibration test and free drop test of the whole vehicle.

[0059] According to a second aspect of this application, a vehicle is provided, including the intelligent domain controller described above.

[0060] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments within the scope of the technology disclosed in this application, or make equivalent substitutions for some of the technical features.
