[0002] In today's era of rapid development in radar technology, millimeter-wave radar plays a crucial role in many fields due to its unique advantages, such as vehicle collision avoidance in intelligent transportation, environmental perception in autonomous driving, and target detection in security monitoring.

[0003] Most radar structures install components inside a housing and then install a sealed base plate at the bottom of the housing. The base plate has holes for wire harnesses to pass through. However, the traditional radar internal component installation structure is rigid, the internal space of the housing is small, and installation and disassembly are cumbersome. Once a component fails, repair is time-consuming and labor-intensive. Repair personnel have to operate in the confined space of the housing, which can easily lead to accidental contact with other components and secondary failures. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-5 As shown, a millimeter-wave radar structure includes a housing 1 and a base 2 fixedly disposed on the lower outer side of the housing 1. The surface of the base 2 has a through groove 3 for fixing bolts to pass through and install. A rectangular frame 4 is fixedly disposed inside the housing 1. A base plate 5 is provided at the lower end of the housing 1. The base plate 5 is fixedly connected to the rectangular frame 4 by connecting bolts 11. A wire hole 10 for wire harness to pass through and install is provided on the surface of the base plate 5. A detachable mounting assembly for installing components is provided inside the housing 1. A sealing assembly that mates with the wire hole 10 is provided at the lower end of the base plate 5. In use, the operator first installs the components on the mounting assembly, and then installs the mounting assembly inside the housing 1. This facilitates the operator to install components on the outside of the housing 1, avoiding the inconvenience of installing components in the small space inside the housing 1. Finally, the base plate 5 is fixedly installed by connecting bolts 11.

[0028] Furthermore, the mounting assembly includes a mounting plate 6 and connecting plates 7 symmetrically arranged on both sides of the lower end of the mounting plate 6. The lower ends of the two connecting plates 7 are respectively provided with fixing plates 8 that are squeezed and clamped by the rectangular frame 4 and the base plate 5. The surface of the mounting plate 6 has multiple mounting holes 9 for mounting components. In use, when the base plate 5 is removed, the squeezing and clamping of the fixing plates 8 is released, and the operator can directly remove the mounting plate 6 so that the components can be installed on the mounting plate 6 on the outside of the housing 1. Then the mounting plate 6 is inserted into the housing 1, and the base plate 5 is installed, so that the fixing plates 8 are clamped between the base plate 5 and the rectangular frame 4.

[0029] Furthermore, the sealing assembly includes a frustum cover 14 and a connecting ring 15. The lower end of the base plate 5 has an annular groove 13 for threaded connection of the frustum cover 14, and the outer surface of the frustum cover 14 has an annular connecting groove 16 for connection of the connecting ring 15. The outer surface of the connecting ring 15 is connected to the inner wall of the annular groove 13 through an elastic element. In use, the frustum cover 14 is first loosened to disengage it from the annular groove 13. Then, the wire harness of the component mounted on the mounting plate 6 passes through the wire hole 10 and the frustum cover 14. Then, the outer surface of the wire harness is wrapped with sealing tape (the sealing tape is placed between the wire hole 10 and the frustum cover 14). Then, the operator threaded the frustum cover 14 onto the annular groove 13, so that the inner wall of the frustum cover 14 is tightly pressed against the outer surface of the sealing tape, achieving a sealing effect.

[0030] Furthermore, the lower end of the mounting plate 6 has multiple slots 12, which creates a gap between the mounting plate 6 and the components, thereby improving heat dissipation.

[0031] Furthermore, the lower end of the rectangular frame 4 is provided with a threaded hole 17 for connecting the bolt 11. A magnet 18 for adsorbing the fixing plate 8 is fixedly embedded at the lower end of the rectangular frame 4. Under the adsorption of the magnet 18, the fixing plate 8 is adsorbed, so that the fixing plate 8 will not fall off directly after the base plate 5 is removed.

[0032] Furthermore, the elastic element is made of rubber. Under the connection of the elastic element, on the one hand, it will not affect the rotational connection of the frustum cover 14, and on the other hand, after the frustum cover 14 is removed, it will not detach from the base plate 5, thus avoiding the frustum cover 14 from being easily lost after it is removed from the base plate 5.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
