1. A folding unit structure, comprising at least one supporting frame and at least one folding frame, wherein
the supporting frame is of a through structure, and the folding frame is arranged on at least one side of the supporting frame; the supporting frame is made of an aluminum alloy profile;
the folding frame comprises a plurality of rims and baffle plates; the rims are hinged to the supporting frame; the baffle plates are detachably mounted in the rims; each rim is made of a strip-shaped aluminum profile, and each baffle plate is made of a plate-shaped aluminum profile;
after being folded, the plurality of rims abut against the supporting frame, or the rims abut against each other, so that the supporting frame and the folding frame form a rectangle structure as a whole;
after being unfolded, the plurality of rims define a cross section with the same area as an area of the supporting frame; and the cross section is configured to connect to another folding unit structure when the folding frame is extended;
wherein the supporting frame comprises two parallel side plates and two parallel connecting plates; each of two ends of the connecting plates presses one of the side plates to form a rectangular frame structure; and
the two side plates and the two connecting plates are both hinged with the rims;
wherein each rim hinged to each of the side plates comprises two parallel longitudinal beams and two parallel cross beams to form a rectangular frame structure;
one of the longitudinal beams is hinged to the side plate, and has a same length as the side plate;
each of two ends of each of the cross beams presses one longitudinal beam; a sum of a length of the cross beam and thicknesses of the two longitudinal beams is a half of a length of each of the connecting plates; and
the baffle plates are arranged between the two longitudinal beams and the two cross beams;
wherein each rim hinged to each of the connecting plates comprises two parallel connecting beams; the two connecting beams are connected through the baffle plates; the connecting beams and the connecting plates have same lengths; and
a distance between opposing outer edges of the two connecting beams is a half of the length of each side plate;
wherein a cross section of each connecting beam is of a square structure, and a cross section of each connecting plate is of a rectangular structure; and
a sum of a thickness of one connecting beam and a width of each connecting plate is equal to a width of each side plate; or, a sum of thicknesses of the two connecting beams and a width of each connecting plate is equal to a width of each side plate.
