Referring to fig. 3, the present embodiment provides a car body 100 leveling system, the car body 100 includes a car bottom plate 110, the car bottom plate 110 is made of a frame structure 111, a plurality of intersection points (see a position a in fig. 3) are formed on the frame structure 111, the car body 100 leveling system includes a plurality of supporting columns 200 and at least three levels 300, wherein the plurality of supporting columns 200 are disposed at the bottom of the car body 100, and are fixedly connected to the frame structure 111 for supporting the car body 100; the supporting columns 200 are provided in a telescopic structure so as to level the car body 100 by adjusting the length of each supporting column 200; the length direction of each level 300 is parallel to the underbody 110, and the length direction of one level 300 intersects at least the length direction of the other two levels 300, and the intersection point is in the height direction of the intersection point. Two I-beams can be used as main beams, a plurality of cross beams are fixedly connected between the two main beams to form a frame structure 111, and a floor is covered at least above the frame structure 111 to form a vehicle bottom plate 110. The car body 100 leveling system of the present embodiment levels the floor by adjusting the height of each support column 200, and makes two levels 300 intersecting in the length direction detect the levelness of two stable triangles (see fig. 4, the angle of view of fig. 4 is the direction of the arrow in fig. 2) by making the length direction of one level 300 intersect at least in the length direction of the other two levels 300, so that after leveling, the floor 110 is more nearly horizontal, the intersection point is in the height direction of the intersection point, to fix the level 300 more stably, and the horizontal base line of the level 300 can be made longer, further making the floor 110 more nearly horizontal after leveling.

Referring to fig. 3 and 5, in one embodiment, each support column 200 is secured to the intersection of the frame structure 111 so that when the height of the support column 200 is adjusted, the level 300 more sensitively detects the degree of adjustment, further bringing the floorboard 110 closer to level after leveling.

The intersection point is in the height direction of the supporting column 200, so that the supporting column 200 is more stably fixed on the frame structure 111. The carriage body 100 can be selected as a cuboid; the number of the support columns 200 may be 4, and the support columns 200 are disposed at intersections closest to four corners of the floor panel 110. 3 gradienters 300 can be arranged, wherein one gradienter 300 is arranged along the diagonal direction of the intersection point which is closest to the four corners of the vehicle bottom plate 110; the other two levels 300 are arranged along the long side direction of the vehicle bottom plate 110.

The metal liquid beads 320 are conductive liquid metal, and may be mercury. For a level 300, when it is horizontal, the metal bead 320 is connected to the middle first electrode pair 330; when the level gauge 300 is tilted, the metal beads 320 slide to both sides and are connected to the second electrode pair 340 or the third electrode pair 350, the tilt state of the current vehicle bottom plate 110 is obtained by detecting the state of the level gauge 300, and the height of the supporting column 200 is adjusted as much as possible, so that the vehicle bottom plate 110 is leveled. Alternatively, the bottom electrode of the first electrode pair 330 is recessed from the center by a predetermined angle, which is preferably greater than 0 ° and less than 2 °, to allow for some tilt error, and the top electrode is also recessed by 0-2 ° as appropriate. Wherein, the insulating liquid can be castor oil, silicon oil or other synthetic artificial insulating oil. Preferably, the insulating oil with good insulating property and large specific gravity is selected, and the insulating liquid has small infiltration on the lead so as to ensure that the metal liquid beads keep better approximately spherical shape. In addition, when the metal beads are selected as mercury beads, the mercury beads are easy to scatter to form a plurality of small mercury beads when the vehicle moves, and the level meter needs to be processed before leveling, for example, one end of the level meter is lifted and stands still, so that the plurality of small mercury beads are synthesized into the whole mercury beads to be used.

In an alternative embodiment, the cross-section of the level 300 is elliptical and circular; the length of the sleeve is about 10cm, and the major diameter of the excircle of the oval ring is 6-8 mm; the minor diameter of the excircle of the elliptical ring is 3-4 mm; the wall thickness of the sleeve 310 is 0.5-2 mm.

The width of each of the first electrode pair, the second electrode pair, and the third electrode was 0.5 mm. The smaller the width of the electrode, the smaller the resistance between the electrode and the metal bead, and the more accurate the leveling result.

Referring to fig. 8, in an alternative embodiment, the system further includes a display panel 400 for displaying the tilt status of each level 300 and for height adjustment of the support posts 200 in the form of buttons 600. For example, the top row of indicator lights corresponds to the top row of levels 300 in FIG. 5, and the diagonal indicator lights corresponds to the diagonal levels 300 in FIG. 5; the bottom row of indicator lights correspond to the bottom row of levels 300 in FIG. 5; the middle indicator lamp 420 of each row is electrically connected to the first electrode pair 330, the left indicator lamp 410 is electrically connected to the second electrode pair 340, and the right indicator lamp 430 is electrically connected to the third electrode pair 350.

The first, second, third and fourth rows of keys are used to control the movement of the support columns 200 at the top left, top right, bottom left and bottom right, respectively, and may be set, for example, to press the left representative to rise, the middle representative to fall and the right representative to stop.
