If there is no threshold structure at the bottom of the door frame, the door panel only needs to have a step corresponding to the door frame or the closed air window on the top, thereby effectively ensuring the sealing performance between the door panel and the door frame or the closed air window;

[0036] It comprises an inner panel 1, an outer panel 2 and a folded edge 3; a gap is left between the inner panel 1 and the outer panel 2 to make the door panel as a whole have a certain thickness, and the gap can be filled with supporting materials, such as honeycomb paper, aluminum honeycomb and other fillers, which is beneficial to enhance the overall structural strength of the door panel; the outer panel 2 comprises a flat plate 2-1, and a side of the flat plate 2-1 corresponding to the hinge side is provided with a bent edge 2-2 extending to the inner panel 1, the end of the bent edge 2-2 is fastened to the inner panel 1, and a step structure 2-5 is provided at the position where the bent edge 2-2 is connected to the flat plate 2-1. The step structure 2-5 can cooperate with the door frame to form a sealing structure. At the same time, the step structure 2-5 can make the flat plate 2-1 extend to the side away from the inner panel 1, thereby increasing the overall thickness of the door panel without affecting the inward opening method. A grooved handle structure is provided on the side of the flat plate 2-1 corresponding to the lock edge, and the notch of the grooved handle structure faces the lock edge. Since the grooved handle structure is at the same height as the outer panel 2, the handle is hidden. Compared with the traditional structure of installing an independent handle, the overall aesthetics of the door panel can be improved and the risk of bumping can be reduced.

[0037] The grooved handle structure can be formed in two ways;

[0038] The first one is combined with Figure 3 and 7 The inner panel 1 and the outer panel 2 are connected to each other at one side of the corresponding locking edge by a folding edge 3, the folding edge 3 includes a baffle 3-1 which is fastened to the inner panel 1 at one side, the baffle 3-1 is provided with an extension edge 3-2 facing the hinge side on the side away from the inner panel 1, and the flat plate 2-1 is provided with a bending flange 2-3 for forming a grooved handle structure on the side corresponding to the extension edge 3-2, and the bending end of the bending flange 2-3 is fastened to the extension edge 3-2 at the same time.
