Device and method for bending vehicle glass

A device for bending vehicle glass, comprising a concave solid lower mold, at least one blowing pipe, and a plurality of extraction pipes, wherein the concave solid lower mold comprises a base and a top plate covered on the base, the base and the top plate cooperatively define an accommodating space, and a plurality of first partitions are arranged in the accommodating space to divide the accommodating space into a plurality of subspaces, the top plate has a carrying surface that is concave and away from the base, and the top plate has a plurality of through holes that are in communication with the accommodating space and arranged at intervals, each of the plurality of subspaces corresponds to at least one of the plurality of through holes, each of the at least one blowing pipe communicates with at least one of the plurality of subspaces and is configured for blowing gas to the at least one of the plurality of subspaces, and the plurality of extraction pipes communicate with the rest of the plurality of subspaces in one-to-one correspondence for extracting gas in the rest of the plurality of subspaces;

• when the plurality of subspaces comprise a central subspaces, a buffer subspace, and a plurality of edge subspaces, wherein the central subspace corresponds to a middle region of the top plate, the buffer subspace surrounds the central subspace, and the plurality of edge subspaces are distributed around the buffer subspace and cooperatively surround the buffer subspace, and the at least one blowing pipe communicates with the buffer subspace or the central subspace, and the plurality of extraction pipes communicate with the other subspaces;
• and
• wherein the plurality of edge subspaces comprise a lower subspace, an upper subspace, a first side subspace, and a second side subspace, the lower subspace and the upper subspace are located at opposite sides of the buffer subspace, the first side subspace and the second side subspace are located at opposite sides of the buffer subspace, and the top plate has a first region corresponding to the lower subspace and a second region corresponding to the upper subspace, wherein a radius of curvature of the first region is greater than a radius of curvature of the second region.
