Folding frame and folding vehicle

A folding frame, comprising a cross beam, a pillar, and a supporting column, wherein the cross beam comprises a front beam and a rear beam;

• a rear-end bottom of the front beam is rotationally connected to a front-end bottom of the rear beam so that the two are capable of being vertically folded, moreover, an angle between a rotational axis of the front beam and a central axis of the rear beam is an acute angle;
• the supporting column comprises a front column and a rear column, the front column is inserted in the front beam to cooperate, a rear end of the front column and the front end of the rear column are rotationally connected so that the two are capable of being folded, and the rear column and the pillar are rotationally connected;
• when the folding frame is in an unfolded state, the rear end of the front beam abuts against the front end of the rear beam, the front end of the front column is inserted in the front beam, and supports below the front beam, the cross beam, the pillar, and the supporting column define a triangular shape;
• and
• when the folding frame is in a folded state, the front column is rotated relative to the rear column to a state in which it is separated from the front beam, and the front beam is rotated relative to the rear beam to the side of the pillar.
