When the door panel is closed, the included angle between the door panel and the vertical direction can be set to be-2 degrees to 0 degree. In this embodiment, one end of the positioning bending convex surface of the hinge linkage connecting piece is hinged to the door panel mounting plate through the hinge linkage connecting piece hinge shaft 9, the hinge linkage connecting piece hinge shaft is located in the positioning groove, the door panel mounting plate 2 is provided with the bending U-shaped groove 21, and the hinge linkage connecting piece and the hinge main body fixing plate are both located in the U-shaped groove. Thereby compact structure connects stably and saves space.
In this embodiment, two sides of the hinge body fixing plate 1 are provided with bent side baffles 14, two second rollers are respectively connected with one side baffle roller, and the two second rollers are respectively installed on two sides of the hinge linkage connecting piece. Therefore, the hinge linkage connecting piece can stably and smoothly slide in the sliding process. Meanwhile, the hinge linkage connecting piece can be better positioned, so that the damping piece is positioned and rubbed with the damping inclined plane on the hinge main body fixing plate. In this embodiment, the damping piece is a damping rubber block, and the damping rubber block is convexly arranged on the hinge linkage connecting piece.
