The door panel body 120 comprises a thin plate structure 121, and two ends of one side of the thin plate structure 121, which is far away from the door liner 140, are respectively provided with a plurality of fixing seats 122; at least the fixing seat 122 and the bracket body 210 abut against each other to form a relative abutting force, so as to limit the bracket body 210 of the display screen assembly 200 to shake in the direction of the plane of the thin plate structure 121, thereby realizing the detachable connection between the bracket body 210 and the fixing seat 122, and pre-installing the bracket body 210 on the side of the door panel body 120 away from the door bladder 140. 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 210, so as to adapt to the preassembly of bracket bodies 210 with different sizes.

In an embodiment, as shown in fig. 7 and 8, the first abutting portion 1125 is a first positioning protrusion, as shown in fig. 9, the second abutting portion 1311 is a first positioning groove, as shown in fig. 10 and 11, a second positioning groove (not shown) abutting against the first abutting portion 1125 is disposed at the top end of the bracket body 210, and a second positioning protrusion (not shown) abutting against the second abutting portion 1311 is disposed at the bottom end of the bracket body 210. The two ends of the bracket body 210 are positioned and preassembled through the fixed seats 122, so that the left and right movement of the bracket body 210 is limited; the first and second contacting

portions

1125 and 1311 limit the upward, downward, and forward and backward movement of the bracket body 210, respectively, to fix the bracket body 210 to the door panel body 120.

In one embodiment, the cover 111 is provided with a recess 1113 for receiving the terminal and/or knock module 113; the hold down cap body 112 covers the recess 1113. A through groove 11131 through which the wiring harness passes is provided in the groove 1113. The cover 111 has a first through hole 11151 for pivotally connecting to the household appliance housing; the pencil of the display screen subassembly 200 of the household electrical appliances door body passes through the logical groove 11131 and then links to each other with binding post, and the pencil in the household electrical appliances box body passes through first through-hole 11151, logical groove 11131 in proper order and then links to each other with binding post.

The knocking module 113 is electrically connected with a main control panel arranged inside the household appliance door body, can identify whether a user performs knocking action on the household appliance door body or not, and indicates the household appliance to respond according to knocking operation of the user so as to sense a vibration signal for knocking the refrigerator door body. For example, a household appliance door is turned on and household appliance lighting is turned on through a tapping action of a user.

The knocking module 113 includes a knocking sensor, and is configured to receive vibration generated when a user knocks the door of the home appliance. The knocking module 113 further comprises a control unit electrically connected with the knocking sensor, the control unit can be directly arranged on a main control panel in the household appliance door body or independently arranged to receive vibration information transmitted by the knocking sensor and judge whether the vibration information is preset knocking vibration, and if the vibration information is preset knocking vibration, an instruction is sent to enable the household appliance door body to respond; if the vibration is not the preset knocking vibration, the household appliance door body does not respond.

As shown in fig. 10, the door further includes a first side molding strip 150 and a second side molding strip 160 for forming two side frame structures of the door frame. The lower end cap body 130, the bracket body 210, the first side decoration strip 150 and the second side decoration strip 160 are flush with the outer surface away from the door liner 140. That is, the outer surface of the glass panel 230 of the door frame abutting the display panel assembly 200 is flush with the outer surface of the bracket body 210 to form a flat outer surface, so that the subsequent installation of the glass panel 230 can be facilitated, and the glass panel 230 can be firmly fixed.

As shown in fig. 2, 3 and 14, the fixing base 122 includes a limiting portion 1221 and a mounting base 1222, and the limiting portion 1221 is protruded on the mounting base 1222. The fixing base 122 is provided with a limiting portion 1221, and the limiting portion 1221 is located on one side of the door panel body 120 away from the door core 140.

The limiting portion 1221 is of a bending structure, the bending direction of the limiting portion 1221 faces the mounting position of the bracket body 210, and the bending directions of the limiting portions 1221 of the two fixing bases 122 forming relative abutting force are opposite to each other so as to clamp two opposite outer sides of the bracket body 210. One side wall of the bracket body 210 extends into the cavity formed by the bending structure of the limiting portion 1221 and the surface of the mounting seat 1222, and limits three surfaces of one side of the bracket body 210, that is, the limiting portions 1221 of the two fixing seats 122 forming relative abutting force respectively clamp two opposite side walls of the bracket body 210, so as to limit the movement of the bracket body 21 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 210 far away from the thin plate structure, that is, the inner wall of the cavity formed by the bending structure of the limiting portion 1221 and the surface of the mounting seat 1222 completely clings to the outer wall of the bracket body 210 far away from the thin plate structure, so as to firmly limit the movement of the bracket body 210 along the direction far away from the thin plate structure 121.

An assembly gap is formed between the inner wall of the bending structure of the limiting portion 1221 and the outer wall of the bracket body, the bracket body 210 can slightly move between the two oppositely arranged fixing seats 122 along the direction towards or away from the fixing seat 122, after the bracket body 210 is clamped into the bending structure of the fixing seat 122, a small distance is left between the inner wall of one side of the fixing seat 122, which is opposite to the bracket body 210, and the bracket body 210, so that the fixing seat 122 is prevented from being attached to the bracket body 210 to increase the clamping difficulty, and the bracket can be clamped conveniently. Due to the bending structure of the fixing seat 122, the two sides of the bracket body 210 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.

As shown in fig. 2 and 4, the thin plate structure 121 has a hole 1211; the position-limiting portion 1221 extends into the hole 1211, and the mounting seat 1222 is connected to an outer wall of the thin plate structure 121. The mounting seat 1222 completely covers the hole 1211 to seal the hole 1211 for facilitating subsequent foaming, so as to prevent foaming overflow, and further, the size of the inner contour of the hole 1211 is larger than the size of the outer contour of the limiting portion 1221, so that the limiting portion 1221 can smoothly extend into the hole 1211. The mounting seat 1222 has a plurality of third through holes 12222, the thin plate structure 121 has a second through hole 1215 corresponding to the position of the third through hole 12222, and in one embodiment, the fixing seat 122 is connected to the thin plate structure 121 by rivets passing through the second through hole 1215 and the third through hole 12222 in sequence. In yet another embodiment, the fixing base 122 is detachably connected to the thin plate structure 121 by screws sequentially passing through the second through hole 1215 and the third through hole 12222.
