Example 1

As shown in fig. 1, the present invention provides a door panel for a household appliance door body, which includes a door panel body 120 for forming a foam door body surrounding structure, wherein the door panel body 120 includes an integrally formed thin plate structure 121 and a plurality of limiting portions 1221; the plurality of limiting parts 1221 are respectively arranged at two ends of one surface of the thin plate structure 121; wherein the content of the first and second substances,

at least two spacing portions 1221 support the body with the support of display screen mutually and lean against, form relative support power to the restriction support body rocks in the direction on sheet structure 121 place plane, realizes the location pre-installation of support body.

The sheet structure 121 is a sheet metal part, and the sheet structure 121 is rectangular. In one embodiment, the thin plate structure 121 is a flat plate structure, and two sides of the thin plate structure are connected to two side decoration strips through two side extrusion strips respectively.

As shown in fig. 2 and 4, the limiting portion 1221 is a bent structure, the bending direction of the limiting portion 1221 faces the mounting portion of the bracket body, and the bending directions of the two limiting portions 1221 forming opposite abutting forces are opposite to each other, so as to limit two opposite outer sides of the bracket body. One side wall of the bracket body extends into the cavity formed by the bending structure of the limiting portion 1221 and the surface of the mounting seat 1222 and abuts against the movement of three surfaces on one side of the bracket body, that is, the limiting portion 1221 forming relative abutting force abuts against two opposite side walls of the bracket body respectively to limit the movement of the bracket body in the direction away from the thin plate structure 121.

Furthermore, the inner wall of the bending structure of the limiting portion 1221 abuts against the outer wall of the bracket body far away from the thin plate structure, that is, the inner wall of the accommodating cavity formed by the bending structure of the limiting portion 1221 and the surface of the mounting seat 1222 is completely tightly attached to the outer wall of the bracket body far away from the thin plate structure, so as to firmly limit the bracket body to move along the direction far away from the thin plate structure 121.

Be equipped with the fit-up gap between spacing 1221's the structure inner wall of buckling and the support body outer wall, the support body card is gone into spacing 1221's the structure of buckling back, leaves small interval between one side inner wall of spacing 1221 relative support body and the support body to avoid fixing base 122 to hug closely with the support body and increase and clamp the degree of difficulty, so that clamp. Due to the bending structure of the limiting part 1221, the two sides of the bracket body are limited in the bending structure of the fixing seat 122, and only slight left-right movement exists, so that the positioning preassembly is not influenced.

The door panel body 120 further includes a fixing seat 122, and the fixing seat 122 is provided with a mounting seat 1222; the limiting portion 1221 is protruded on the mounting seat 1222, and the mounting seat 1222 is detachably connected to the thin plate structure 121. The number of the fixing bases 122 and the positions on the thin plate structure 121 are determined according to the size of the bracket body, so as to adapt to the preassembly of bracket bodies with different sizes.
