Detailed Description

Specific embodiments of the present utility model will be described below with reference to the accompanying drawings. As shown in fig. 1 to 6: a blind area radar correction device consists of a laser emission mechanism 1 and a correction bracket mechanism 2,

an angle detector 24 is arranged on the support 17, a calibration plate 25 is further arranged on the sliding sleeve 10, and a calibration grid is drawn on the calibration plate 25.

The working process of the blind area radar correction device of the embodiment of the utility model is as follows: when the blind area radar installed at the tail of a vehicle needs to be checked, firstly, a laser emission mechanism is taken and installed on a rear wheel of the vehicle at one side to be checked, specifically, a plurality of magnetic bases 5 are utilized to connect a connecting disc 3 on a hub of the rear wheel, and as all the magnetic bases 5 can relatively move in an arc-shaped groove 4, a worker can adjust the facing angle of the connecting disc 3 so as to ensure that a laser generator 6 strictly maintains a horizontal state, and after adjustment, a knob on the magnetic bases 5 is rotated to enable the magnetic bases 5 to show magnetism, and the connecting disc 3 is fixed;

then the correction bracket mechanism 2 is placed at the tail of the blind area radar side, the correction plate 25 can receive a cross cursor emitted by the laser generator 6, the state of the cross cursor on the correction plate 25 is checked, the relative position between the correction bracket mechanism 2 and the vehicle is adjusted through the relative position relation, the size and other parameters of the correction grid and the cross cursor, three adjustable feet 8 are respectively adjusted after the position is proper, the leveling instrument 13 is observed in real time in the adjusting process, the leveling instrument 13 stops adjusting after reaching the level, then the sliding sleeve 10 is driven to drive all mechanisms on the leveling instrument to move longitudinally relative to the supporting column 9, the sliding sleeve 10 is fixed on the supporting column 9 by utilizing the locking knob 11 after being adjusted to a proper height, then the angle detector 24 is placed on the support 17, the first fastening bolt 18 is used for fixing the sliding sleeve 10, then the adjustable bracket 14 is driven to slide along the length direction of the horizontal bracket 12, specifically, the sliding block 22 at the bottom of the adjustable bracket 14 slides in the horizontal bracket long groove 23 arranged on the horizontal bracket 12, the adjustable bracket 14 moves to a position matched with the tail bolt of the vehicle, the adjustable bracket 14 is fixed with the horizontal bracket 12 in a screwing mode through the second fastening knob 21,
