It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.

It is noted that all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs unless otherwise indicated.

In the present utility model, unless otherwise indicated, terms of orientation such as "upper, lower, top, bottom" are used generally with respect to the orientation shown in the drawings or with respect to the component itself in the vertical, upright or gravitational direction; also, for ease of understanding and description, "inner and outer" refers to inner and outer relative to the profile of each component itself, but the above-mentioned orientation terms are not intended to limit the present utility model.

In order to solve the problem that a circuit board for controlling a display screen is arranged at the rear of the display screen in the prior art, the display screen and the circuit board are thicker in superposition thickness, and the circuit board cannot be arranged on an ultrathin refrigerator door body.

As shown in fig. 1-9, an embodiment of the present utility model provides a refrigerator door body, which includes a door body 1 and a display assembly 2, wherein the display assembly 2 includes a mounting seat 21, a display 22 and a circuit board 23 electrically connected to the display, the mounting seat 21 includes a first portion 211 located in the door body 1, the display 22 and the circuit board 23 are respectively disposed on opposite sides of the first portion 211, and an orthographic projection of the circuit board 23 on the first portion 211 is not overlapped with an orthographic projection of the display 22 on the first portion 211.

In the above arrangement, when the display 22 and the circuit board 23 are connected to the first portion 211, the orthographic projections of the display 22 and the circuit board 23 on the first portion 211 are not overlapped, so that concave portions can be simultaneously arranged on two opposite sides of the first portion 211 or on any one of the opposite sides, and the display 22 and/or the circuit board 23 are arranged at the concave portions, so that the overall thickness of the display assembly 2 is ensured to be smaller than the overall thickness of the display assembly 2 when the display 22 and the circuit board 23 are overlapped, so as to adapt to a thinner refrigerator door body.

It is obvious that when the display 22 and the circuit board 23 are connected to the first portion 211 and the front projection of the two onto the first connection portion 211 has an overlapping portion, the sum of the thickness of the display 22, the thickness of the circuit board 23 and the thickness of the portion of the first portion 211 located between the display 22 and the circuit board 23 is a limit value that has to be considered in the design of the thickness of the display assembly 2. That is, in such a case, the thickness of the display assembly 2 would only be greater than or equal to the limit value.

In this embodiment, since the display 22 and the circuit board 23 are offset, the recess may be formed on both opposite sides of the first portion 211 or on any one of the opposite sides. Then, when the display 22 and/or the circuit board 23 are provided in the recessed portion, the display 22 and the circuit board 23 do not interfere with each other, and the thickness of the display module 2 can be designed to be thinner than the above-described limit value.

Specifically, the first portion may be provided with a first groove 2111 on a side on which the circuit board 23 is mounted, and the circuit board 23 is disposed within the first groove 2111.

In this embodiment, a plurality of fixing posts 2112 are further disposed in the first groove 2111, and the circuit board 23 is fixed to the plurality of fixing posts 2112 by screws. In some embodiments, a clamping portion may be disposed inside the groove wall of the first groove 2111, so as to clamp the circuit board 23 on the clamping portion. The arrangement of the circuit board 23 in the first groove 2111 is not limited in the present utility model.

It will be appreciated that, since the display 22 and the circuit board 23 are not overlapped, the circuit board 23 can not emit radiation to the outside of the refrigerator door again by using the metal parts in the display 22 as the protection parts. Therefore, the radiation protection unit 24 is required to be disposed at a position on the inner bottom wall of the first groove 2111 with respect to the circuit board 23.

It should be noted that, since the provision of the radiation protection unit 24 also indirectly has some adverse effect on the overall thickness design of the display assembly 2, the radiation protection unit 24 may preferably be provided as a conductive silver paste coating formed on the inner bottom wall of the first recess 2111. The arrangement can play a role in effectively preventing radiation through the conductive silver paste coating on one hand; on the other hand, the thickness of the conductive silver paste coating is very small, which has little effect on the thickness design of the display assembly 2.

Optionally, the thickness of the conductive silver paste coating can be set between 0.1 and 0.5mm, so that the radiation-proof function can be ensured, and the coating cost is convenient to save.

It should be noted that, the circuit board 23 may form an orthographic projection on the inner bottom wall of the first groove 2111, so that radiation emitted from the circuit board 23 may be prevented by coating the area with the conductive silver paste in theory.

However, in the actual use process of the refrigerator, the user does not always have to be in the position corresponding to the circuit board 23 when opening the refrigerator door, and when the user is in a position deviated from the position corresponding to the circuit board 23, some radiation rays are emitted from the side of the circuit board 23. Although the intensity of the radiation is smaller than that of the radiation emitted by the circuit board 23 to the orthographic projection area on the first portion 211, it is necessary to apply the conductive silver paste coating in an extending manner beyond the orthographic projection of the circuit board 23 on the first portion 211, in addition to the conductive silver paste coating on the orthographic projection area of the circuit board 23 on the inner bottom wall of the first recess 2111, from the environmental and safety viewpoints.

Specifically, in the present embodiment, the conductive silver paste coating has a first coating region 241 overlapping with the orthographic projection of the circuit board 23 on the inner bottom wall of the first groove 2111 and a second coating region 242 formed by coating extending outward in the circumferential direction of the first coating region.

In this embodiment, when the length extending outward along the circumferential direction of the first coating area 241 is between 10 and 15mm, the radiation rays emitted laterally from the circuit board 23 can be well blocked.

Optionally, a protective cover 231 may be further covered on the circuit board 23, where the protective cover 231 is fixedly connected to the first portion 211, without affecting the overall thickness of the display assembly 2.

Preferably, a second groove 2113 is further provided on a side of the first portion on which the display is mounted, and the display 22 is disposed within the second groove 2113.

In some embodiments, the display surface of the display 22 may be disposed flush with the end surface of the wall of the second groove 2113, so that a clearer display effect can be achieved.

Generally, the door body 1 includes two side frames, an inner liner, a door panel 11 and two end caps 12. The two end covers 12 are clamped at the upper end and the lower end of the side frames on the two sides to form a door frame, the door plate 11 is connected to one side of the door frame, and the door liner is connected to the other side of the door frame. Then, foaming liquid is injected into a cavity enclosed by the side frames, the inner lining, the door plate 11 and the two end covers 12 for foaming, so that the door body 1 is formed.

In this embodiment, as shown in fig. 2-3, the refrigerator door further includes a mounting box 3 located in the door body 1, the mounting box 3 has a first opening 31 in a front direction and a second opening 32 in a lateral direction, the door panel 11 is disposed on the first opening 31, a light-transmitting portion 111 is disposed on the door panel 11, and a surface of the first portion 211 on which the display 22 is mounted faces the door panel 11, so that a display surface of the display 22 is disposed facing the light-transmitting portion 111.

Further, the end cover 12 is sleeved on the outer side of the second opening 32, and the first portion 211 may pass through the second opening 32 and be disposed in a cavity enclosed by the mounting box 3, the door panel 11 and the end cover 12.

As set forth above, the first portion 211 is prevented from being disposed in the foaming layer in the door body 1, and when the display 22 and the circuit board 23 mounted on the first portion 211 are damaged, the first portion 211 of the mounting base 21 can be detached from the mounting box 3 and the first portion 211 can be taken out from the second opening 32 for repair of the components mounted on the first portion 211.

When the first portion 211 is taken out of the second opening 32, the display 22, the circuit board 23, and the protective cover 231 covered on the circuit board 23 mounted on the first portion 211 may be taken out of the second opening 32.

Preferably, the end cover 12 is provided with a mounting opening 121, a wall of the mounting opening 121 is sleeved on the outer side of the second opening 32, the mounting seat 21 further includes a second portion 212 extending from the first portion to the second opening 32, and the second portion 212 is penetrated in the second opening 32 and fixedly connected to the end cover 12.

It will be appreciated that since the wall of the mounting opening 121 is disposed over the outer side of the second opening 32, the display 22, the circuit board 23, and the protective cover 231 disposed over the circuit board 23 mounted on the first portion 211 can still be removed from the second opening 32, and the mounting opening 121 is disposed without any interference from the first portion 211 entering or exiting the second opening 32.

So configured, the first portion 211 of the mounting block 21 can be installed into the mounting box through the mounting port 121 without having to disassemble the end cap 12.

Of course, in the event of a failure of the display 22 or circuit board 23, the first portion 211 can be removed from the mounting opening 121 without disassembling the end cap 12.

Optionally, in order to prevent external dust or foreign matter from entering the chamber through the second opening 32, the mounting opening 121 is further covered with a cover 122, and a connection portion of the cover 122 is connected to an end of the end cap 12 away from the inside of the door body 1.

In summary, the following technical effects are achieved by the embodiments of the present utility model:

the front projection of the display 22 and the circuit board 23 on the first portion 211 are not overlapped, and a concave portion can be arranged on two opposite sides of the first portion 211 or on any one of the opposite sides, so that the display 22 and/or the circuit board 23 are arranged on the concave portion, and the overall thickness of the display assembly 2 is further ensured to be smaller than that of the display assembly 2 when the display 22 and the circuit board 23 are overlapped, so as to adapt to a thinner refrigerator door body.
