[0039] See Figure 1 , Figure 1 Figure XX of a radar device 100 provided in an embodiment of the present application is shown. The radar device 100 provided in an embodiment of the present application includes a circuit board 110 and a housing 120. The circuit board 110 is provided with an interface component K on one side along a first direction F1. The housing 120 is provided to cover the circuit board 110, and the housing 120 and the circuit board 110 are detachably provided. The housing 120 includes a first plate assembly 121 provided along the first direction F1. The first plate assembly 121 includes a first side plate 1211 and a second side plate 1212 adjacently provided and detachably connected along a second direction F2. The first side plate 1211 is provided with a first opening t1, and the second side plate 1212 is provided with a second opening t1 opposite to the first opening t1. A through hole is defined between the first opening t1 and the second opening t1, and the interface component K passes through the through hole. The first direction F1 is parallel to the horizontal surface of the circuit board 110, and the second direction F2 is perpendicular to the first direction F1.

[0040] Specifically, the circuit board 110 can be a ceramic circuit board 110, an alumina ceramic circuit board 110, an aluminum nitride ceramic circuit board 110, or a PCB board, and a microcontroller chip can be provided on the circuit board 110. The circuit board 110 is provided with interface components K on both sides opposite to each other along the first direction F1. There are multiple interface components K. The interface components K can be conductive connectors or power supply interfaces. The types of the multiple interface components K can be the same or different. One end of at least one interface component K is welded to a conductive terminal of the circuit board 110. The housing 120 has a top and a cavity. The housing 120 is provided outside the circuit board 110. The housing 120 and the circuit board 110 are detachably connected, such as by screwing, to facilitate partial or complete removal of the housing 120 from the circuit board 110.

[0041] Furthermore, the housing 120 includes a first plate assembly 121 arranged along the first direction F1. There are two first plate assemblies 121, and the two first plate assemblies 121 are arranged opposite each other along the first direction F1. Each first plate assembly 121 includes a first side plate 1211 and a second side plate 1212. The first side plate 1211 and the second side plate 1212 are stacked and detachably connected along the second direction F2. For example, the first side plate 1211 and the second side plate 1212 are screwed together to facilitate the disassembly and assembly of the first side plate 1211 and the second side plate 1212. Furthermore, the first side plate 1211 is provided with a plurality of first openings t1, and the second side plate 1212 is provided with a plurality of second openings t1. Each first opening t1 corresponds to a second opening t1, defining a corresponding through hole, and each through hole is penetrated by an interface member K. It should be noted that the shape of the through hole can be a circular hole, a square hole, or a hole of other shapes, and can be set according to actual conditions. This embodiment is not limited here.

[0042] In this embodiment, the housing 120 and the circuit board 110 are detachably arranged to facilitate the removal of part or all of the housing 120 from the circuit board 110. The housing 120 includes a first plate assembly 121 arranged along the first direction F1, and the first plate assembly 121 includes a detachable first side plate 1211 and a second side plate 1212. A through hole for the interface member K to pass through is defined between the first side plate 1211 and the second side plate 1212. In this way, when the housing 120 and the circuit board 110 are disassembled, the first side plate 1211 and the second side plate 1212 can be removed. Disassembly avoids loose soldering of the interface part K and the conductive terminals on the circuit board 110, so that the circuit board 110 can be directly disassembled together with the interface part K, and it also facilitates the assembly process. When the circuit board 110 is placed in the shell 120, the interface part K is passed through a first opening t1 corresponding to the first side plate 1211, and then the interface part K is installed and fixed through the second opening t1 corresponding to the second side plate 1212 and the first opening t1. This can effectively improve the disassembly and installation efficiency, reduce the welding and loose soldering processes, and reduce the requirements for installation tools and operating environment.

[0043] Continue reading Figure 2 , and combined with Figure 3 In some embodiments, a first limiting groove r1 is provided on the first side plate 1211, and a second limiting groove r2 opposite to the first limiting groove r1 is provided on the second side plate 1212.

[0044] Specifically, a plurality of first limiting grooves r1 are provided on the first side plate 1211, and a plurality of second limiting grooves r2 are provided on the second side plate 1212. A notch is provided on one side of each first limiting groove r1, and a notch is also provided on one side of each second limiting groove r2. The notch of each first limiting groove r1 and the notch of a corresponding second limiting groove r2 are arranged opposite to each other, and a limiting space is defined between the first limiting groove r1 and the second limiting groove r2. The fixing plate of the interface part K is placed in the limiting space. In this way, the position of the interface part K can be limited to reduce the lateral displacement of the interface part K.

[0045] Continue reading Figure 2 and Figure 3 In some embodiments, the interface component K is detachably connected to the first side panel 1211. Furthermore, the interface component K is detachably connected to the second side panel 1212. Specifically, for each interface component K, a screw hole is provided at the bottom of the first limiting groove r1 and the bottom of the second limiting groove r2, and two spaced screw holes are provided at the fixing plate of the interface component K. One screw hole of the fixing plate and the corresponding screw hole on the bottom of the first limiting groove r1 are fixed by screws, and the other screw hole of the fixing plate and the corresponding screw hole on the bottom of the second limiting groove r2 are fixed by screws. In this way, the position of the interface component K can be fixed, and during the process of plugging and unplugging the interface component K, the circuit board 110 will not be affected by the force, thereby improving the stability of the interface component K.

[0046] Continue reading Figure 2 In some embodiments, two first board assemblies 121 are provided, and the two first board assemblies 121 are arranged opposite to each other along the first direction F1; wherein, the shell 120 also includes a cover plate 123 and two second board assemblies 122 arranged opposite to each other along the third direction F3; the two first board assemblies 121 and the two second board assemblies 122 enclose a frame; the circuit board 110 is arranged in the frame, and the cover plate 123 is detachably arranged on the frame.

[0047] Specifically, the first plate assembly 121 can be considered the short-side plate assembly, and the second plate assembly 122 can be considered the long-side plate assembly. The two first plate assemblies 121 and the two second plate assemblies 122 enclose a frame, which has a rectangular planar shape. The cover plate 123 is placed over the frame and screwed to the frame, securing the circuit board 110 within the frame. This facilitates disassembly and assembly of the housing 120, improving the efficiency of disassembly and assembly of the radar device 100.

[0048] Continue reading Figure 2In some embodiments, the shell 120 also includes a second plate assembly 122 arranged along the third direction F3, and the second plate assembly 122 includes a third side plate 1221 and a fourth side plate 1222 that are adjacently arranged along the second direction F2 and detachably connected, the third side plate 1221 is detachably connected to the first side plate 1211, and the fourth side plate 1222 is detachably connected to the second side plate 1212.

[0049] It should be noted that in this embodiment, the third side panel 1221 and the fourth side panel 1222 are separate structures. In other embodiments, the third side panel 1221 and the fourth side panel 1222 are integrated structures. In this embodiment, the third side panels 1221 and 1221 are fixed to each other by screwing, and the third side panel 1221 and the first side panel 1211 are fixed to each other by screwing. This facilitates quick disassembly and assembly of the side panels of the housing 120.

[0050] See Figure 4 In some embodiments, the radar device 100 further includes a heat dissipation assembly 130 disposed at the bottom of the circuit board 110 . The heat dissipation assembly 130 includes a detachably connected heat conductor 131 and a heat dissipation member 132 . The heat conductor 131 is disposed inside the housing 120 , and the heat dissipation member 132 is disposed outside the housing 120 .

[0051] Specifically, the heat conducting member 131 is configured as a heat conducting plate, and the heat sink 132 is configured as a heat sink. In this embodiment, the heat sink 132, the heat conducting member 131 and the circuit board 110 are stacked in sequence, and the heat conducting member 131 and the heat sink 132 are in contact with each other so as to achieve a heat dissipation effect on the circuit board 110. In this embodiment, the two third side panels 1221 arranged along the second direction F2 are fixedly connected to the heat conducting member 131, that is, an integrated structure, which facilitates the installation of the side panels of the housing 120. It is understandable that in this embodiment, by providing the heat dissipation assembly 130 including a detachably connected heat conducting member 131 and a heat sink 132, when the circuit board 110 is updated or changed, it is only necessary to replace the heat conducting member 131 without replacing the heat sink 132, thereby improving the compatibility of the heat sink 132.

[0052] For further information, see Figure 4 The heat sink 132 is provided with heat sinks arranged at intervals on the side away from the heat conducting member 131. The heat dissipation assembly 130 also includes a fan 133. The fan 133 is provided on one side of the heat sink 132 to facilitate heat dissipation of the circuit board 110 and improve heat dissipation efficiency.

[0053] In some embodiments, the two opposing surfaces of the heat conducting member 131 and the heat dissipating member 132 are bonded together and coated with thermal grease. Specifically, the two opposing surfaces of the heat conducting member 131 and the heat dissipating member 132 are substantially smooth and bonded together, and the bonding surfaces are coated with thermal grease to improve heat conduction efficiency and thus heat dissipation efficiency.

[0054] Continue reading Figure 4 In some embodiments, a heat-conducting platform 1311 of different heights and sizes is provided on the surface of one side of the heat-conducting member 131 close to the circuit board 110, and a thermal grease pad is filled between each heat-conducting platform 1311 and a heat-generating component on the circuit board 110. Specifically, a plurality of heat-conducting platforms 1311 are provided on the surface of one side of the heat-conducting member 131 close to the circuit board 110, and there is a gap between each heat-conducting platform 1311 and a corresponding heat-generating component on the circuit board 110. In an embodiment, the indirect distance is 0.7 mm, and in other embodiments, the indirect distance is 0.6 mm, 0.8 mm or 0.9 mm, etc. In this way, direct hard contact between the heat-generating component and the heat-conducting platform 1311 can be avoided, which may cause extrusion damage to the component or conduction short circuit. Furthermore, in this embodiment, a 1 mm thick thermal grease pad is filled in the gap. The thermal grease pad is soft, compressible and insulating, and can also improve the heat conduction efficiency to improve the heat dissipation efficiency.

[0055] Furthermore, a plurality of support columns 1312 are fixed to the side of the heat conducting member 131 adjacent to the circuit board 110. Specifically, the heat conducting member 131 is supported on the bottom surface of the circuit board 110 by the support columns 1312. Furthermore, in this embodiment, each support column 1312 is provided with a screw hole, and the circuit board 110 is provided with screw holes corresponding to the screw holes of the support columns 1312. The circuit board 110 and the support columns 1312 are detachably fixed together by screwing, thus facilitating assembly and disassembly of the circuit board 110 and the heat conducting member 131.

[0056] Continue reading Figure 4 In some embodiments, the radar device 100 further includes a mounting base 140 , which is connected to the heat sink 132 ; the mounting base 140 is used for external installation.

[0057] Specifically, two mounting brackets 140 are provided. One mounting bracket 140 is screwed onto one side of the heat sink 132 along the first direction F1, and the other mounting bracket 140 is screwed onto the other side of the heat sink 132 along the first direction F1. The two mounting brackets 140 are used for external mounting and can be screwed together. In this way, the radar device 100 can be externally mounted using the mounting brackets 140, while also being easily assembled and disassembled.

[0058] Continue reading Figure 4 In some embodiments, the radar device 100 further includes a shielding box 150 disposed in the housing 120 . The shielding box 150 is located on a side of the circuit board 110 away from the heat conductor 131 and covers a portion of the circuit board 110 .

[0059] Specifically, the radar device 100 may include a shielding box 150 of varying sizes and shapes. The shielding box 150 includes a shielding frame 151 and a shielding cover 152. The shielding frame 151 is positioned over the area of ​​the circuit board 110 where components are located, and the shielding cover 152 is positioned within the shielding frame 151. This shielding function can shield signals and prevent electromagnetic interference with components.

[0060] In summary, by making the shell 120 and the circuit board 110 detachable, it is convenient to disassemble part or all of the shell 120 from the circuit board 110, and by setting the shell 120 to include a first plate assembly 121 arranged along the first direction F1, the first plate assembly 121 includes a detachable first side panel 1211 and a second side panel 1212, and a through hole for the interface part K to pass through is defined between the first side panel 1211 and the second side panel 1212. In this way, when the shell 120 and the circuit board 110 are disassembled or assembled, the interface part K can be avoided from being loosened or welded by disassembling or splicing the first side panel 1211 and the second side panel 1212, thereby effectively improving the disassembly and assembly efficiency of the radar device 100, reducing the welding and loosening processes, and reducing the requirements for installation tools and operating environment. Furthermore, by providing the heat conductor 131 between the heat sink 132 and the circuit board 110, when the circuit board 110 is updated or modified, only the heat conductor 131 needs to be replaced, without replacing the heat sink 132, thereby improving the compatibility of the heat sink 132. Furthermore, in the radar device 100 of this embodiment, components such as the cover plate 123, the first side panel 1211 assembly, the second side panel 1212 assembly, the circuit board 110, the heat conductor 131, and the heat sink 132 are all secured using screws, facilitating disassembly and assembly, and allowing for targeted replacement of related components, thereby improving component versatility.
