As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

For example, a door structure comprising a glass panel, a display screen, and a foam door body; the display screen is arranged on the glass plate; the glass plate is provided with a plurality of screw cylinder columns, and each screw cylinder column is provided with a screw hole; the foaming door body is provided with a plurality of hanging holes, each screw cylinder column penetrates through one hanging hole, the foaming door body is connected with the glass plate through a plurality of screws in a threaded manner, and each screw is fixed on one screw hole of the screw cylinder column in a threaded manner.

For example, a refrigerator includes the door structure. The door body structure comprises a glass plate, a display screen and a foaming door body; the display screen is arranged on the glass plate; the glass plate is provided with a plurality of screw cylinder columns, and each screw cylinder column is provided with a screw hole; the foaming door body is provided with a plurality of hanging holes, each screw cylinder column penetrates through one hanging hole, the foaming door body is connected with the glass plate through a plurality of screws in a threaded manner, and each screw is fixed on one screw hole of the screw cylinder column in a threaded manner.

For example, a method for assembling a door structure for a refrigerator includes the steps of: foaming the door body with a plurality of hanging holes; clamping the display screen on the glass plate; a plurality of screw cylinder columns with screw holes are injected on the glass plate; inserting each screw cylinder column into one hanging hole in a one-to-one correspondence mode, and enabling the glass plate to be hung on the foaming door body; and screwing a screw into the screw hole of the screw cylinder column to fix the glass plate on the foaming door body.

In one embodiment, as shown in fig. 1, a door body structure 10 includes a glass panel 100, a display screen 200, and a foam door body 300; namely, the door 300 is foamed in advance, and then the display screen 200 is disposed on the glass plate 100; specifically, for example, a plurality of screw cylinder columns 110 are arranged on the glass plate 100, and each screw cylinder column has a screw hole; referring to fig. 2, a plurality of hanging holes 310 are formed in the foam door 300, each of the screw cylinder columns 110 is inserted into one of the hanging holes 310, the foam door 300 is screwed with the glass plate 100 by a plurality of screws 400, and each of the screws 400 is screwed and fixed to a screw hole of one of the screw cylinder columns 110. For example, the number of the barrel screws 110 is 4, and each barrel screw 110 is disposed at a corner of the glass plate 100. Similarly, the door 300 is correspondingly provided with 4 hanging holes 310, so that the glass plate 100 can be hung on the door 300 when the screw cylinder 110 is inserted into the hanging holes 310 on the door. In order to enable the glass plate to be hung on the door body more stably, the number of the screw cylinder columns and the hanging holes can be 5 or more than 5.

It is understood that the hanging hole 310 can be opened before the door body is foamed or after the door body is foamed, and the hanging of the glass plate on the door body is not affected whether the hanging hole is opened before the foaming operation or after the foaming operation. Specifically, the display screen 200 and the glass plate 100 are assembled first, and then the glass plate 100 structure integrated with the display screen 200 is mounted on the foamed door body 300 together. Thus, the glass plate 100 is hung on the foam door 300 together with the display screen 200 without foaming. And the glass plate and the door body are glued together by adopting a traditional mode and then are foamed, then a plastic piece with the same structural size as the display screen is arranged on the glass plate in a die-opening mode, and the display screen is arranged on the glass plate. Therefore, the glass plate is pre-foamed, and a large deformation is generated on the surface of the glass plate, and the deformation amount is usually not less than 2mm in the length direction and not less than 1.5mm in the width direction. Therefore, the touch control and display effect of the screen can be seriously affected after the display screen 200 is installed, the bad phenomena of touch control failure and the like can occur after the display screen is used for a long time, and the reject ratio and the rejection ratio of the display screen after installation are correspondingly higher.

In this embodiment, the glass plate 100 and the door 300 are assembled by a screw fixing method, specifically: a plurality of screw cylinder columns 110 are disposed on the glass plate 100, wherein the screw cylinder columns 110 may be made of a metal material or other materials with certain hardness. And each screw cylinder column is provided with a screw hole. Thus, when the glass plate 100 is assembled on the door body 300, each screw cylinder column 110 on the glass plate 100 is respectively inserted into the corresponding hanging hole 310 on the foam door body 300, so that the screw cylinder column protrudes out of one side of the foam door body away from the glass plate, and at the moment, each screw cylinder column 110 is screwed tightly through a screw 400, so that the glass plate 100 can be fixedly hung on the foam door body 300. It can be understood that each screw 400 has a nut 410, wherein the diameter of the nut 410 is larger than the diameter of the screw hole 400 and is also larger than the diameter of the hanging hole 310, so that when the screw is screwed into the screw hole, finally the nut 410 abuts against the screw hole and the periphery of the hanging hole, thereby ensuring that the screw cylinder does not slip out of the hanging hole, which affects the stability of the glass plate 100 hanging on the foam door body 300.

In addition, since the glass plate 100 and the foam door 300 are connected by a screw fixing method, the glass plate 100 is more easily detached from the foam door 300 than by an adhesive fixing method. Therefore, when the display screen 200 needs to be switched in a customized mode, the glass plate 100 provided with the display screen 200 only needs to be detached from the foaming door body 300, so that the operation of the display screen 200 is simpler due to the fact that the glass plate is detached from the foaming door body, and the operation is easy. That is, only the display screen 200 arranged on the glass plate 100 needs to be replaced independently, so that the customization switching operation of the display screen becomes more convenient, and the production cost investment of the customization switching of the display screen on the foaming door body is greatly reduced.

According to the door body structure, firstly, the door body 300 is foamed, then the display screen 200 is fixedly connected with the glass plate 100, and the screw cylinder column 110 which is injected on the glass plate 100 penetrates through the hanging hole 310 on the foamed door body, so that the glass plate 100 provided with the display screen 200 is fixedly hung on the foamed door body 300. Therefore, the glass plate 100 is not deformed due to the foaming of the door 300, and the display screen 200 arranged on the glass plate 100 has good display effect and touch effect. And because the display screen 200 and the glass plate 100 are assembled in advance and then hung on the foaming door body 300, the customization switching of the display screen 200 can be conveniently carried out only by replacing the glass plate 100 provided with the display screen 200 for the same door body 300 structure without carrying out die sinking manufacture, thereby reducing the investment of production cost.

To facilitate the mounting of the barrel screw 110 on the glass plate 100, for example, referring to fig. 3 to 5, the barrel screw 110 is injection molded on the glass plate 100. That is, the barrel screw 110 is injected onto the glass plate 100 together with the injection molding material by injection molding, and after the injection molding material is cooled and solidified, the barrel screw is stably fixed in the injection molding material. The injection molding material can be plastic or other rubber materials, and the injection molding material can be dropped on the glass plate at high temperature and can be stably fixed on the glass plate after being cooled.

In order to further stably mount the screw cylinder on the glass plate, for example, the screw cylinder 110 includes a base 111 and a cylinder body 112, the base 111 is mounted on the glass plate 100, the cylinder body 112 is connected to an end of the base 111 away from the glass plate 100, the screw hole is formed in the cylinder body 112, and a width of the base 111 is greater than a width of the cylinder body 112. For example, the base 111 of the screw cylinder and the body 112 of the cylinder are both injection molded on the glass plate 100, or adhered to the glass plate by using strong glue, it is understood that only a part of the cylinder body 112 is injection molded or adhered to the glass plate 100 together with the base 111, and the other part is used for penetrating through the door 300 to fix the door and the glass plate by means of screw fixation. It can be understood that the width of the base 111 is greater than the width of the barrel body 112, so as to form a clamping structure, which is more convenient for fixing and has better fixing effect when the screw barrel is fixed by injection molding or gluing. For example, the base 111 has a circular cross-section, which has a larger contact surface with the glass sheet than a base having a rectangular cross-section with the same width, which further facilitates the secure attachment of the barrel screws to the glass sheet.

For example, a plurality of bases 120 are molded on the glass plate 100, and each screw cylinder column 110 is inserted into one of the bases 120, wherein the base has an accommodating cavity, that is, a base 120 structure is formed on the surface of the glass plate 100 by a molding material, and the screw cylinder column 110 is fixed in the accommodating cavity of the base 120, so that the screw cylinder column 110 with a certain hardness can be stably arranged on the glass plate 100, and the glass plate 100 is hung on the foam door 300 through the screw cylinder column 110. For example, since the base 120 is injection molded together with the base 111 of the screw cylinder and a part of the structure of the cylinder body 112 through an injection mold, the screw cylinder is reinforced and fixed, is not easily loosened, and can be stably fixed on the glass plate 100 because the base and the cylinder body form a clamping structure that is injection molded in the base 120. In one embodiment, referring to fig. 6, the base 120 includes a connecting body 121 and a plurality of supporting ribs 122, the supporting ribs 122 are respectively disposed on the periphery of the connecting body 121, and the connecting body 121 can be injection-molded on the glass plate through an injection mold, so that when the screw cylinder column 110 is inserted into the connecting body 121, the screw cylinder column 110 is supported by each supporting rib 122. Thus, the connector 121 having the support rib 122 can more stably fasten the screw cylinder 110 to the glass panel 100, thereby ensuring that the glass panel 100 can be stably hung on the door 300.

In order to ensure the uniformity and safety of the foam door structure when the screw cylinder columns are inserted into the foam door, for example, please refer to fig. 7 to 9, the foam door 300 includes a plurality of screw pre-embedded boxes 320, and each screw cylinder column 110 and one screw 400 screwed thereto are accommodated in one of the screw pre-embedded boxes 320. It can be understood that the screw embedded box 320 has a fixing cavity corresponding to the size and structure of the screw cylinder column and the screw, and the screw cylinder column 110 penetrating through the foam door body and the screw 400 for fixing the screw cylinder column are both fixed in the fixing cavity of the screw embedded box 320. It can be understood that, as shown in fig. 1, the screw 400 has a nut 410, and the diameter of the nut is larger than the diameter of the screw hole of the screw cylinder and the diameter of the hanging hole, so that the screw abuts against the foamed door body, and the glass plate is stably fixed on the foamed door body. Therefore, due to the arrangement of the foaming embedded box, a messy fixed structure cannot be formed on the foaming door body, a door body structure with a uniform structure is formed, and due to the fact that the screw embedded box is an insulator, the screw cylinder columns and screws which are fixed in the fixed cavity and made of metal materials cannot conduct electricity, and potential safety hazards of the door body structure are caused. In addition, the general foam door 300 includes a door shell 330 and a door liner 340, and the screw embedded box 320 is disposed between the door shell 330 and the door liner 340 in the foam door.

In order to completely seal the fixing cavities of the screw embedding boxes, for example, referring to fig. 2 again, the foam door 300 includes a plurality of sealing boxes 350, and each sealing box 350 seals one of the screw embedding boxes 320. It can be understood that the fixing cavity of the screw embedding box 320 has two openings, wherein the screw cylinder column 110 penetrates into the fixing cavity through one side of the screw embedding box 320, and the other opening of the screw embedding box 320 extends into the screw hole of the screw cylinder column 110 through the screw 400 for fastening. The screw cannot completely shield the other side opening of the fixed cavity, so that the insulativity of the screw and the screw cylinder column arranged in the fixed cavity is ensured, the sealing box is arranged at the side opening, so that the screw embedded box is completely sealed, and the screw cylinder column and the screw which are fixed in the fixed cavity and made of metal materials cannot be conducted, so that the potential safety hazard of the door body structure is caused.

In order to reliably dispose the display screen on the glass plate to ensure a good touch effect of the display screen, for example, the door shell 330 is provided with a clamping edge structure for embedding the door frame of the display screen 200. Wherein, for example, the display screen 200 is attached to the glass plate 100 by glue. It can be understood that, an installation frame for installing the display screen is provided on the glass plate, wherein the installation frame is aligned with the door frame and correspondingly has a clamping edge structure. The display screen 200 and the glass plate 100 are fixed together by means of gluing. For example, the display screen can be tightly attached to the glass plate by using a VHB tape, so that there is little or no gap between the glass plate and the display screen, thereby ensuring that the display screen has good touch effect and display effect.

In addition, for example, a plastic part is disposed on the glass plate 100, and the display screen 200 is fixedly connected to the glass plate 100 through the plastic part. Namely, a plastic member capable of fixing the display screen 200 is disposed at the periphery of the mounting frame of the glass plate 100, for example, the plastic member is an elastic gasket or a plastic frame with a mounting groove, so that the display screen 200 is clamped on the elastic gasket or mounted in the plastic frame with the mounting groove, thereby integrating with the glass plate and tightly connecting with the glass plate 100 without a gap. Therefore, the display screen and the glass plate are connected together in a gap, when the display screen 200 needs to be switched, the whole glass plate 100 can be detached from the foaming door body 300, and then a new glass plate 100 with the display screen is replaced. Namely, the switching of the display screen is carried out by adopting an integral replacement mode. Adopt such mounting means can effectively avoid adopting traditional mode, when carrying out the display screen and switching, need use the die sinking utensil to carry out the die sinking operation again at the glass board that sets up on the foaming door body, not only the operation is difficult for carrying out, and need drop into more processing costs when the die sinking operation, is unfavorable for normal production and processing.

In order to reduce the thickness of the door structure, for example, please refer to fig. 2 again, the foaming door 300 includes a foaming embedded box 360, the foaming embedded box 360 has a reserved space, and one side of the display screen 200 protrudes into the reserved space. The foaming embedded box 360 is used for placing foaming agent in the foaming embedded box 360 before the glass plate 100 is installed on the door body 300, so that the door body is foamed, the door body 300 has good heat insulation performance or other performances, and the foaming agent is determined according to different placed foaming agents, and is not repeated herein. After the foaming of door body 300 is finished like this, the pre-buried box 360 of foaming is then idle, in order to reduce a body thickness, will have certain thickness the display screen 200 inlays to be located during the space at the pre-buried box 360 of foaming place, then need not to reserve certain space alone when the preparation door body and be used for installing display screen 200, and directly aim at the display screen the pre-buried box 360 of foaming set up and make it inlay to locate in the pre-buried box space of foaming to make the thickness of whole door body structure obtain greatly reducing.
