Preferably, a sealing strip is provided on the second inclined surface 121 or the first inclined surface 111, which helps to improve the sealing and waterproof performance after the second inclined surface 121 contacts the first inclined surface 111.

[0045] Reference Figure 5 One end of the square shaft 31 is fixedly connected to the motor 311, and the motor 311 is fixedly installed on the bottom wall of the housing 11.

[0046] In this preferred embodiment, the motor 311 is able to drive the square shaft 31 to rotate when it is working.

[0047] In use, the control motor 311 operates, driving the square shaft 31 to rotate. When the square shaft 31 rotates, it drives the first movable tube 32, the second bevel gear 33, the second movable tube 34, and the third bevel gear 35 to rotate. By controlling the extension and retraction of the first electric telescopic rod 42 and the third electric telescopic rod 46, the second bevel gear 33 on the first lifting member 21 meshes with the first bevel gear 219, and the second bevel gear 33 on the second lifting member 22 meshes with the first bevel gear 219. At this time, the square shaft 31 rotates, driving the second bevel gear 33 on the first lifting member 21 and the second lifting member 22 to rotate. The first lifting member 21 and the second lifting member 22 simultaneously push the movable plate 13 to rise. At this time, the radar body 14 moves above the housing 11 and can perform detection.

[0048] By controlling the extension and retraction of the first electric telescopic rod 42 and the third electric telescopic rod 46, the second bevel gear 33 on the first lifting member 21 is disengaged from the first bevel gear 219. At this time, the height of the first lifting member 21 is fixed, and the second lifting member 22 can adjust the tilt of the movable plate 13 by raising or lowering, thereby adjusting the elevation angle detected by the radar body 14, which is beneficial to increasing the adjustment angle range of the radar body 14.

[0049] The third electric telescopic rod 46 is controlled to extend and retract, causing the second bevel gear 33 on the second lifting member 22 to disengage from the first bevel gear 219. At this time, the inclination of the movable plate 13 is fixed. By controlling the extension and retraction of the second electric telescopic rod 44, the third bevel gear 35 is controlled to mesh with the fourth bevel gear 36. At this time, the square shaft 31 rotates, and the square shaft 31 drives the fourth bevel gear 36 to rotate through the third bevel gear 35. The fourth bevel gear 36 drives the fifth bevel gear 38 to rotate through the transmission shaft 37. The fifth bevel gear 38 drives the sixth bevel gear 39 to rotate. The sixth bevel gear 39 drives the second gear 154 to rotate through the rotating shaft 155. The second gear 154 drives the first gear 153 to rotate. The first gear 153 can drive the support shaft 152 to rotate. The support shaft 152 can drive the radar body 14 to rotate. In the horizontal direction, the detection angle of the radar body 14 can be adjusted, which is beneficial to increasing the adjustment angle range of the radar body 14.

[0050] When the radar body 14 needs to be retracted into the housing 11, the first lifting member 21 and the second lifting member 22 are first controlled to move up and down, adjusting the movable plate 13 to a position level with the bottom wall of the housing 11. Then, the first lifting member 21 and the second lifting member 22 are simultaneously controlled to descend, driving the movable plate 13 to descend. At this time, the third bevel gear 35 and the fourth bevel gear 36 disengage. The movable plate 13 drives the rotating member 15 and the radar body 14 to descend, and the top cover 12 covers the top of the housing 11. The second inclined surface 121 contacts the first inclined surface 111, sealing the space inside the housing 11. This not only provides dust and water protection for the radar body 14, but also ensures that the top cover 12 is flush with the vehicle shell, avoiding any protrusion on the windshield, thus optimizing the overall appearance of the vehicle, reducing wind resistance during driving, and reducing noise generated at high speeds.
