[0002] Traffic millimeter-wave radar is a high-frequency, high-performance roadside sensor that accurately perceives traffic conditions. It usually relies on millimeter-wave radar to fully perceive road conditions, traffic flow, safety incidents, etc., so as to output information such as the location, speed, and vehicle length of each target in real time, and continuously track the running trajectory, real-time dynamic speed, running direction, following distance and other data of each vehicle. Through the networking and linkage of multiple radars, the same target can be continuously tracked and located. It is widely used in application scenarios such as high-speed real-time digital twins, vehicle-road collaboration, autonomous driving, green highways, and smart highway management, empowering the new infrastructure of smart highways.

The adapter structure includes a first adapter plate and a second adapter plate arranged vertically, and the mounting structure includes a mounting member, a first rotating member and a first fastener. The first rotating member is inserted through the first adapter plate and the mounting member so that the mounting member can rotate relative to the first adapter plate around the rotation axis of the first rotating member, and the mounting member and the first adapter plate can be fixed by the first fastener. The fixed structure includes a fixing member, a second rotating member and a second fastener. The second rotating member is inserted through the second adapter plate and the fixing member so that the fixing member can rotate relative to the second adapter plate around the rotation axis of the second rotating member, and the fixing member and the second adapter plate can be fixed by the second fastener.

6. The millimeter wave radar installation device according to claim 5, characterized in that: The arc slide rail (201) is in the shape of an arc curve, and the corresponding central angle thereof is less than ninety degrees; the upper edge of the fixing plate (20) corresponding to the flat hole (210) is rotatably connected to a guide wheel (203) for straightening the thick rope (31).

7. The millimeter wave radar installation device according to claim 6, characterized in that: The rotation center of the L-shaped clamping flap (21) is located at its turning point, and one end of the L-shaped clamping flap (21) close to the center of the fixing plate (20) is a smooth arc-shaped curved edge that is convenient for pressing and sliding.

8. The millimeter wave radar installation device according to claim 7, characterized in that: The limit baffle (22) is a block-shaped structure with a bent middle portion. The two limit baffles (22) are located between the two fixed blocks (23). One end of the spring (231) close to the hinge shaft (26) is connected to the upper end of the limit baffle (22). All the springs (231) are at the same height, and the springs (231) are always in a stretched state. When the two L-shaped clamping flaps (21) rotate, so that the corresponding cylindrical pins (212) slide upward along the arc slide rail (201) to the highest point, the two cylindrical pins (212) simultaneously enter between the two limit baffles (22), and the cylindrical pins (212) on the same side contact the limit baffle (22).

9. The millimeter wave radar installation device according to claim 8, characterized in that: A vertical slide groove (202) is provided at the center of the back side of the fixed plate (20); a slider (240) is fixedly connected to the front end of the concave plate (24) coaxially with the hinge shaft (26); the slider (240) is slidably connected in the vertical slide groove (202); the concave plate (24) and the convex plate (25) are always symmetrical to each other.

10. A millimeter wave radar installation method, using the millimeter wave radar installation device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. First, the user needs to install and debug the millimeter-wave radar in the radar housing (3), and install the radar cover (32) on the radar housing (3) by means of bolts; S2. Subsequently, two thick ropes (31) are fixed to the top surface of the radar shell (3) at the lower part of the device; S3, then, sleeve the fixing ring (262) onto the upper protrusion (161); S4, then, adjusting the handle (150) so that the angle control rod (15) is in a horizontal state, thereby the top rod (17) is in a horizontal state and the fixing plate (20) is in a vertical state; S5, rotating the rotating rod (142) so that the winch (141) tightens the thick rope (31), thereby lifting the radar housing (3) upward; S6. Afterwards, the top surface of the radar housing (3) contacts one end of the L-shaped clip (21) corresponding to the cylindrical pin (212) and continues to move upward, so that the top surface of the radar housing (3) gradually pushes the L-shaped clip (21) to rotate until the plug-in protrusion (211) is plugged into the curved groove piece (30) and the two cylindrical pins (212) are both inserted between the two limit stoppers (22), and the radar is installed; S7. Subsequently, the handle (150) is continuously raised and pressed down to control the up and down angle of the radar until it reaches a suitable angle. The handle (150) is held and rotated along the rotating rod (14) to adjust the left and right angle of the radar until it reaches a suitable angle.
