Two groups of integrated frames 14 are symmetrically installed at the bottom end of the support plate 4. A base 7 is arranged below the support frame 1. Two groups of floor feet 12 are symmetrically installed on the outer wall of the base 7;

[0024] First, install the UWB module 5 at the top of the support plate 4, and install the device inside the vehicle through the floor bolts 12. The UWB module 5 is used to position the vehicle. When it is necessary to adjust the angle of the UWB module 5, turn on the adjustment motor 2. The adjustment motor 2 drives the gear 9 to rotate through the transmission shaft 8. Under the mutual meshing of the gear 9 and the toothed disc 6, and with the movable cooperation of the support sleeve 21 with the support shaft 3 and the driven shaft 10 respectively, the gear 9 drives the toothed disc 6 to rotate around the support shaft 3. With the auxiliary movable support of the driven shaft 10, the toothed disc 6 drives the support plate 4 to rotate around the driven shaft 10, and the support plate 4 drives the UWB module 5 to rotate, so as to rotate and adjust the use angle of the UWB module 5. Turn on the servo motor 11. The servo motor 11 drives the worm 19 to rotate. Under the mutual meshing of the worm 19 and the worm wheel 20, the worm 19 drives the worm wheel 20 to rotate. The worm wheel 20 drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the support frame 1 to rotate. The support frame 1 drives the support plate 4 and the UWB module 5 to rotate, so as to circularly rotate and adjust the position of the UWB module 5, so as to adjust the use direction of the UWB module in multiple positions, receive signals from different directions, realize convenient rotation and adjustment of the angle of the UWB module, facilitate circular rotation and adjustment of the UWB module for use, and improve the flexibility of use;
