[0086] It can be understood that the back plate 12 is split into two parts of a plate body 122 and a rear frame 123 for facilitating assembly and disassembly of the mounting frame 20 and the transparent plate 122. The plate body 122 is a main part of the back plate 12, and has an outer shape matched with the panel 11 and is arranged opposite to the panel 11. A second opening 121 is formed in the plate body 122 corresponding to the first opening 111. The upper and lower ends of the plate body 122 are connected and fixed to the upper and lower ends of the panel 11 through first and second end covers respectively. The rear frame 123 is a frame structure, which can be a frame structure close to a flat plate, so that the rear frame 123 can be connected with the plate body 122 to form a flat plate-shaped back plate 12. The outer edge of the rear frame 123 can be connected with the plate body 122 by clamping or bonding. Specifically, the rear frame 123 can be connected to the side of the plate body 122 away from the panel 11, and the connection position is located at the outer periphery of the second opening 121, so that the inner side of the rear frame 123 can be located in the second opening 121 to shield the avoiding gap 1221. After the transparent plate 30 is fixed to the mounting frame 20 through the connecting part, the rear frame 123 is installed at the second opening 121 to shield the connecting part and the rear side of the mounting frame 20, so as to realize simple and beautiful appearance of the rear side of the door assembly 102 and improve user experience.

[0087] As shown in Figures 12-16 some embodiments of the present application, the plate body 122 has a plurality of avoiding gaps 1221 corresponding to the positions of the connecting part along the circumference of the second opening 121. The connecting part includes a pressing block 41 and a bolt. The pressing block 41 is connected with the second frame 22 through the bolt, the axis of the bolt passes through the avoiding gap 1221, and the rear frame 123 is installed on the side of the plate body 122 away from the panel 11. In the direction perpendicular to the panel 11, the projection of the avoiding gap 1221 falls into the projection of the rear frame 123.

[0088] It can be understood that the connecting part is realized by a pressing block 41 capable of moving in a direction perpendicular to the panel 11 and a bolt controlling the pressing block 41, the pressing block 41 can be a cubic structure, the pressing block 41 is provided with a bolt hole penetrating through the pressing block 41, the pressing block 41 is fixed on the second frame body 22 by the bolt, the bolt is vertically connected to a side of the second frame body 22 facing the back plate 12, a part of the pressing block 41 is located in the frame opening of the second frame body 22, so that the part can be pressed on the transparent plate 30 in the second frame body 22 after the bolt is tightened, and then the transparent plate 30 is pressed on the first frame body 21, so as to realize the fixation of the transparent plate 30. In order to facilitate the tightening operation of the connecting part, a plurality of avoiding notches 1221 are arranged at the inner edge of the plate body 122, that is, the edge of the second opening 121, the positions of the avoiding notches 1221 correspond to the connecting part, and the area of the avoiding notches 1221 can accommodate the pressing block 41 to be put in or taken out, so that the assembly of the connecting part and the transparent plate 30 can be conveniently operated from the avoiding notches 1221. In order to ensure the simplicity and beauty of the back side of the door assembly 102, the avoiding notches 1221 are shielded by the rear frame 123, the rear frame 123 can be fixed to the edge of the second opening 121 by a clamping structure or adhesion, and part of the rear frame 123 extends into the second opening 121 to shield the avoiding notches 1221. Specifically, in the direction perpendicular to the panel 11, the avoiding notches 1221 are located between the rear frame 123 and the panel 11, and the avoiding notches 1221 are completely shielded by the rear frame 123 from the rear frame 123, so that the appearance of the back side of the door assembly 102 is simple and beautiful, and the user experience is improved.

The annular groove 1224 can be flanged from the edge of the panel 122 toward the panel 11 and then flanged toward the center of the second opening 121, forming an L-shaped annular flange that defines the rear frame 123. The shape of the rear frame 123 is adapted to the annular groove 1224, so that the rear frame 123 can be snapped into the annular groove 1224, thereby improving the reliability of the connection between the rear frame 123 and the panel 122.

[0093] like Figures 12-13 As shown, in some embodiments of this utility model, the plate 122 is provided with a plurality of hanging holes 1222, which are spaced apart circumferentially along the second opening 121. The rear frame 123 is provided with a plurality of hooks 1231, which are inserted into the hanging holes 1222 so that the rear frame 123 is suspended on the side of the plate 122 away from the panel 11.

[0094] It is understandable that multiple hanging holes 1222 can be opened on the periphery of the second opening 121 on the panel 122. Multiple hanging holes 1222 can be provided on both sides of the width direction of the panel 122. In cooperation, multiple hooks 1231 are provided on the side of the rear frame 123 facing the panel 11. The hooks 1231 have downward grooves.

The first connecting hook 1233 and the second connecting hook 221 can be arranged forward and backward along the direction perpendicular to the panel 11, so that when the rear frame 123 is matched with the plate body 122 from top to bottom, the first connecting hook 1233 and the second connecting hook 221 are matched to realize forward and backward limiting. In the width direction of the rear frame 123, the first connecting hook 1233 and the hook 1231 can be arranged at opposite ends of the rear frame 123 respectively. When the rear frame 123 is installed, the hook 1231 on one side is connected and matched with the hanging hole 1222, and the first connecting hook 1233 on the other side is limited and matched with the second connecting hook 221 to improve the connection reliability of the rear frame 123.
