By adjusting the height of the spacer 20, the height of the spacer 20 from the ground can be measured accurately by the distance measuring device 30. The cushion block 20 is used for abutting against a vehicle, when the cushion block 20 abuts against the vehicle, the height between the vehicle and the ground is equal to the height between the cushion block 20 and the ground, and therefore when the height between the vehicle and the ground needs to be calibrated, the height between the cushion block 20 and the ground only needs to be calibrated.
Specifically, in the actual use process, when the height of the vehicle needs to be calibrated, the height of the cushion block 20 is firstly adjusted, so that the height between the cushion block 20 and the ground is adjusted to the height of the vehicle which needs to be calibrated. In the adjusting process, the height between the cushion block 20 and the ground is accurately measured through the distance measuring instrument 30, and the height between the cushion block 20 and the ground is equal to the height of the vehicle needing to be calibrated.
Then, the height of the vehicle body of the vehicle is raised to be higher than the height of the vehicle to be calibrated by adjusting the suspension system, the vehicle height calibration device is placed below the vehicle, and then the height of the vehicle body of the vehicle is slowly reduced until the vehicle is in contact with the cushion block 20, so that the vehicle cannot continuously reduce the height of the vehicle body. At the moment, the height of the vehicle body of the vehicle is consistent with the height of the cushion block 20 from the ground, the distance between the cushion block 20 and the ground is adjusted to be the height of the vehicle to be calibrated, the height of the vehicle body of the vehicle at the moment is the height of the vehicle to be calibrated, and a user only needs to record the height of the vehicle at the moment through a height sensor of the vehicle and take out the vehicle height calibration device, so that the calibration of the height of the vehicle can be completed.
According to the vehicle height calibration device, the height between the cushion block 20 and the ground is adjusted, and the distance between the cushion block 20 and the ground is accurately measured through the distance meter 30, so that the distance between the cushion block 20 and the ground can be accurately adjusted to be the height of any vehicle required to be calibrated, and the accurate calibration of any height of the vehicle can be realized. Compared with the traditional vehicle calibration method, the vehicle height calibration device abandons the mode of manually measuring the height of the vehicle body for many times, and adopts the mode of measuring by the distance meter 30, so that the error of vehicle height calibration is smaller. In addition, because manual measurement is not needed, a large amount of labor and time cost are saved, and meanwhile, the potential safety hazard during vehicle calibration can be reduced.
Specifically to the embodiment of fig. 1, the direction of gravity is up and down.
