[0002] The cross-door refrigerator forms a closed space when closed. To ensure that there is no cold leakage between the left and right doors, a flip beam needs to be added to the left refrigerator door to form a mechanical flip structure. When the door is open, the flip beam is perpendicular to the door surface. When the door is closed, the flip beam is guided by the flip beam guide block on the top of the foam box, and the flip beam is parallel to the door surface. At this time, the left and right refrigerator doors and the flip beam form a closed space. At the same time, in order to prevent condensation caused by cold leakage from the door, a heating wire is pre-embedded in the flip beam. The pre-embedded wire box structure determines the production method of the door and the flipping method of the door flip beam, which in turn affects the sealing and insulation effect of the refrigerator.

[0015] Compared with the prior art, the wire box assembly of the present invention has at least the following beneficial effects:

[0016] The embodiment of the present invention discloses a wire box assembly, which is arranged on the side of the door shell assembly facing the door liner assembly. Since the wire box assembly has a docking chamber, one end of the connecting line between the door shell assembly and the door liner assembly extends into the docking chamber.

[0039] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0040] In the description of the present invention, it should be clarified that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, but are not necessarily used to describe a specific order or sequence; the terms "vertical", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "horizontal", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention, and do not mean that the referred device or element must have a specific direction or position, and therefore cannot be understood as a limitation on the present invention.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] For a cross-door refrigerator, in order to ensure that the left and right doors can be opened and closed normally, and to form a closed space when closed, a flip beam needs to be added to the left refrigerator door to form a mechanical flip structure to ensure that there is no cold leakage between the left and right doors. When the door is open, the flip beam is perpendicular to the door surface. When the door is closed, the flip beam is guided by the flip beam guide block on the top of the foam box, and the flip beam is parallel to the door surface. At this time, the left and right refrigerator doors and the flip beam form a closed space. At the same time, in order to prevent condensation caused by cold leakage from the door, a heating wire is pre-embedded in the flip beam. The pre-embedded wire box structure determines the production method of the door body and the flipping method of the door body flip beam, which in turn affects the sealing and insulation effect of the refrigerator.

[0043] The original door structure is as follows Figure 8-9As shown, it is composed of a door shell assembly 1, a door liner assembly 2, a wire box 5, a first wiring harness 6 and a second wiring harness 7, wherein the door shell assembly 1 is installed in the lower mold of the foaming mold, and the door liner assembly 2 and the wire box 5 are assembled and installed in the upper mold of the foaming mold. The terminal at one end of the first wiring harness 6 is pre-installed in the wire box 5 on the door liner assembly 2, and the other end is connected to the heating wire wiring in the flip beam when the refrigerator is assembled. The terminal at one end of the second wiring harness 7 passes through the center hole of the rotating shaft 13 of the upper end cover 12 of the door shell assembly 1 and is connected to the refrigerator body wiring in the general assembly process, and the terminal at the other end is placed in the door shell for standby. The connection between the first wiring harness 6 and the second wiring harness 7 requires the foaming assembly line to be stopped and the two terminals of the first wiring harness 6 and the second wiring harness 7 to be manually plugged in. This process requires the assembly line to be stopped, resulting in low efficiency.

[0044] In addition, since the angle of quality inspection after the upper and lower molds are opened is an obtuse angle, in order to ensure normal connection, the total length of the first harness 6 and the second harness 7 needs to be 2m, while the upper end cover of the door shell component 1 and the position of the wire box 5 after the mold is closed actually only need 1m, which leads to material waste. During the process of plugging the terminals, people need to stand on the equipment to operate, which is dangerous. Because the harness is too long, there is a quality risk that the harness will be pressed on the outside of the door body during the mold closing process, causing the door body to be scrapped.

[0045] Example 1

[0046] like Figure 1-9 As shown, an embodiment of the present invention provides a wire box assembly, which is applied to a refrigerator door body. The refrigerator door body includes a door shell assembly 1, a door liner assembly 2 and a flip beam assembly arranged on one side of the door liner assembly 2, and a through hole 211 is provided on the side of the door liner assembly 2 facing the flip beam assembly. The wire box assembly is arranged on the side of the door shell assembly 1 facing the door liner assembly 2, and the wire box assembly has a docking chamber 31. One end of the connecting line 8 between the door shell assembly 1 and the door liner assembly 2 extends into the docking chamber 31. When the door shell assembly 1 and the door liner assembly 2 are buckled together, the mouth of the docking chamber 31 at least partially overlaps with the through hole 211.

[0047] In this embodiment, by arranging the wire box assembly on the side of the door shell assembly 1 facing the door liner assembly 2, since the wire box assembly has a docking chamber 31, one end of the connecting wire 8 between the door shell assembly 1 and the door liner assembly 2 extends into the docking chamber 31, and when the door shell assembly 1 and the door liner assembly 2 are buckled, the mouth of the docking chamber 31 and the through hole 211 at least partially overlap. Compared with the existing design technology, the wire box assembly of this embodiment can complete the connection between the refrigerator door body and the flip beam line through only one connecting wire 8, and there is no need to stop the machine to manually plug the two terminals of the first wiring harness 6 and the second wiring harness 7, thereby improving production efficiency. In addition, the length of the wire is reduced, and the waste of materials is reduced. The problem of the danger of people standing on the equipment to operate during the plug-in terminal process is avoided. In addition, the quality hidden danger of the door body being scrapped due to the wiring harness being too long and the wiring harness being pressed on the outside of the door body during the mold closing process is avoided.

[0048] The wire box assembly of this embodiment can realize that the door shell assembly 1 is installed in the lower mold of the mold, and the door liner assembly 2 is installed separately in the upper mold of the mold, thereby shortening the length of the wire. Compared with the existing pre-buried structure: the wire harness connecting the refrigerator door body and the flip beam can be shortened from 2m to 1m; the flip beam wire harness insertion station is eliminated, reducing one person; at the same time, the scrapping caused by the leakage of the wire harness is completely eliminated.

[0049] In some embodiments, the wire box assembly includes a pre-buried wire box 3, which is arranged on the side of the door shell assembly 1 facing the door liner assembly 2 and extends to the side of the first flange 21 of the door liner assembly 2 away from the flip beam assembly, and the docking chamber 31 is constructed on the side of the pre-buried wire box 3 facing the first flange 21, and the through hole 211 is opened at a position opposite to the first flange 21 and the mouth of the docking chamber 31. When the door shell assembly 1 and the door liner assembly 2 are buckled, it is ensured that the mouth of the docking chamber 31 at least partially overlaps with the through hole 211.

[0050] In some embodiments, the side of the wire box assembly facing the first flange 21 is also constructed with a accommodating chamber 32, the accommodating chamber 32 and the docking chamber 31 have a first channel 33, and a second channel 34 is provided between the accommodating chamber 32 and the space where the door shell assembly 1 and the door liner assembly 2 are engaged. One end of the connecting wire 8 passes through the center hole of the rotating shaft 13 of the upper end cover 12 of the door shell assembly 1 and is connected to the refrigerator body wiring during the assembly process, and the other end passes through the second channel 34, the accommodating chamber 32, and the first channel 33 in sequence to enter the docking chamber 31, and then extends out from the through hole 211.

[0051] When the connecting wire 8 is too long, it can be stored in the accommodating chamber 32, avoiding the potential quality problem of the door body being scrapped due to the wire harness being pressed against the outside of the door body during the mold closing process due to the wire harness being too long.

[0052] In some embodiments, the accommodating chamber 32 is located on a side of the docking chamber 31 facing the door shell assembly 1 , so that the wiring is more reasonable.

[0053] In some embodiments, the wire box assembly further includes a base 4, the base 4 is disposed on a side of the door shell assembly 1 facing the door liner assembly 2, and the pre-buried wire box 3 is plugged and locked on the base 4. During specific assembly, the base 4 can be first fixed to the side of the door shell assembly 1 facing the door liner assembly 2, which can be fixed by bonding, welding, etc., and then the pre-buried wire box 3 is plugged and locked on the base 4 to achieve assembly of the wire box assembly and the door shell assembly 1.

[0054] In some embodiments, the base 4 is configured with at least a pair of spaced-apart first elastic arms 41 on a side facing the pre-buried wire box 3, and at least one of the pair of first elastic arms 41 is configured with a first locking protrusion 411 on a side away from the other first elastic arm 41, and the pre-buried wire box 3 is configured with a first docking plate 35 on a side facing the base 4, and the first docking plate 35 is configured with a first plugging hole 351 that is plugged in one-to-one with the first elastic arm 41, and the first locking protrusion 411 is clamped on the side of the first docking plate 35 away from the base 4. The structure of this embodiment can enable the pre-buried wire box 3 to be plugged and locked on the base 4.

[0055] In some embodiments, a first positioning column 42 is constructed on one side of the base 4 facing the embedded wire box 3, and a first positioning hole 352 corresponding to the positioning column is constructed on the embedded wire box 3. The first positioning column 42 is plugged into the first positioning hole 352, and the base 4 is easily positioned relative to the embedded wire box 3 through the plug-in cooperation with the first positioning column 42 and the first positioning hole 352, thereby improving the assembly efficiency and accuracy. When the door shell assembly 1 and the door liner assembly 2 are buckled together, it is ensured that the mouth of the docking chamber 31 at least partially overlaps with the through hole 211.

[0056] In some embodiments, the embedded wiring box 3 is constructed with at least one pair of spaced-apart second elastic arms on the side facing the base 4, and at least one of the pair of second elastic arms is constructed with a second locking protrusion on the side away from the other second elastic arm. The base 4 has a second docking plate on the side facing the embedded wiring box 3, and the second docking plate is constructed with second plugging holes that are plugged in one-to-one with the second elastic arms. The second locking protrusion is clamped on the side of the second docking plate away from the embedded wiring box 3. The structure of this embodiment can enable the embedded wiring box 3 to be plugged and locked on the base 4.

[0057] In some embodiments, the pre-buried wire box 3 is configured with a second positioning column on one side facing the base 4, and the base 4 is configured with a second positioning hole corresponding to the positioning column. The plug-in cooperation between the second positioning column and the second positioning hole facilitates the positioning between the base 4 and the pre-buried wire box 3, improves the assembly efficiency and accuracy, and ensures that the mouth of the docking chamber 31 at least partially overlaps with the through hole 211 when the door shell assembly 1 and the door liner assembly 2 are buckled.

[0058] In some embodiments, the base 4 has an extension portion 43 on the side facing the first flange 21, and the extension portion 43 abuts against the first side wall 11 of the door shell assembly 1, wherein the first side wall 11 is the side wall corresponding to the first flange 21. In this embodiment, the abutment with the first side wall 11 of the door shell assembly 1 facilitates the positioning of the base 4 and improves the assembly efficiency and accuracy.
