Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

The utility model is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 3 and 4, the present application includes a fixing plate 1 for fixing a bracket to a vehicle body or a vehicle frame; the supporting balls 2 are fixed between the fixed plate and the support plate, so that a revolute pair is formed between the support plate and the supporting balls; and the support plate 3 is used for fixing the laser radar 4 and adjusting the pitching angle of the laser radar 4.

It should be noted that both yaw and pitch angle adjustments are possible.

In a preferred embodiment, as shown in fig. 5, the fixing plate 1 may be formed by directly machining a steel plate or by welding a steel plate and then machining, the first spherical groove 11 in the middle of the fixing plate 1 (the maximum depth of the first spherical groove 11 is between 1/4 and 1/3 diameters of spheres) is used for fixing the supporting sphere 2, the through hole 13 in the periphery of the fixing plate 1 is used for fixing the fixing plate 1 to the vehicle body (the fixing structure may be fixed by bolts), and clamping, pressing or welding may also be used herein; the fixed plate 1 is also provided with 4 uniformly distributed first threaded holes 12 which are matched with the fastening bolts 5 of the bracket plate 3 in a downward locking way.

In the preferred embodiment, as shown in fig. 6, the supporting ball 2 is a steel ball with a diameter of 30mm-60mm, and is installed between the fixing plate 1 and the bracket plate 3 to support the bracket plate 3, so that the bracket plate 3 can freely rotate around the supporting ball 2.

In a preferred embodiment, as shown in fig. 7 and 8, the supporting plate 3 can be formed by directly machining a steel plate or by machining after welding the steel plate, a second spherical groove 34 in the middle of the bottom of the supporting plate 3 (the maximum depth of the second spherical groove 34 is between 1/4 and 1/3 sphere diameters) is used for fixing the structure of the supporting ball 2, 4 first through holes 31 (without screw threads in the holes) and 4 jackscrew threaded holes 32 are uniformly distributed on the periphery of the supporting plate 2, and the fastening bolts 5 are screwed and matched with the first threaded holes 12 of the fixing plate 1 through the first through holes 31 of the supporting plate; the 4 jackscrew threaded holes are in threaded fit with the jackscrew bolt 6, and the lower end of the jackscrew bolt 6 is directly jacked to the plane of the fixing plate after being screwed into the 4 jackscrew threaded holes of the bracket plate 3; the support plate 3 is provided with 4 fixing holes 33 for fixing the laser radar.

This scheme support with automobile body and laser radar fixed back, can adjust laser radar 4 along arbitrary direction pitch angle deflection, the biggest pitch angle can reach more than 10, can realize different biggest pitch angles through the shape of adjustment mounting panel 3 and the diameter of support ball 2 and with the biggest degree of depth of support ball complex spherical recess.

When adjusting 4 angles of laser radar, earlier loosen jackscrew bolt 6 and fastening bolt 5 soon, then adjust 4 every single move angle of laser radar and reach optimal state, then adjust jackscrew bolt 6, wait that the top of jackscrew bolt 6 is whole to lock fastening bolt 5 after 1 contacts with fixed plate, the fastening of mounting panel 3 is realized to the straining force through fixing bolt 5 and jackscrew bolt 6's holding power, wherein, the internal diameter of first through-hole 31 is greater than fastening bolt 5's diameter, preferably, the internal diameter of first through-hole 31 is 1.6 times of fastening bolt 5's diameter, can increase the flat bed between fastening bolt's tip and the first through-hole 31, thereby make bolted connection more firm.
