[0027] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0028] As used herein, terms indicating spatial relative positions such as "upper," "above," "lower," and "below" are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. Terms of spatial relative position may be intended to include different orientations of the device in use or operation in addition to the orientation shown in the drawings. For example, if the device in the figure is turned over, units described as being "below" or "beneath" other units or features will be located "above" the other units or features. Thus, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein interpreted accordingly.

[0029] Reference Figure 1 In one embodiment of the present invention, a refrigerator device 1 is provided. The refrigerator device 1 includes a refrigerator 2 and a cabinet 3. The refrigerator 2 is embedded in the household cabinet 3. The refrigerator 2 includes a box body with a storage chamber formed inside and a door body assembly 100 rotatably arranged relative to the box body. The door body assembly 100 is used to open or close the box body.

[0030] Combination Figure 2-5 As shown, the door body assembly 100 includes a door body 10, a door panel 60 covering the door body 10, and an assembly assembly 20 for fixing the door body 10 and the door panel 60. The door body 10 is rotatably connected to the box body through a rotating shaft hinge, the door panel 60 is connected to and covers the door body 10, and the door panel 60 is simultaneously connected to the cabinet 3 through another hinge and rotates relative to the cabinet 3. It can be seen that the door body 10 rotates around the axis of the rotating shaft hinge, and the door panel 60 rotates around the axis of the other hinge, and the axes of the two hinges do not overlap. The assembly assembly 20 is fixedly connected to the door body 10 and the door panel 60, respectively, and allows the door body 10 and the door panel 60 to slide relative to each other, so that the door body 10 and the door panel 60 can be opened and closed synchronously relative to the box body 200.

[0031] Preferably, the assembly component 20 includes a base 30 for fixing to the door body 10 and a sliding member 40 for fixing to the door panel 60, wherein the sliding member 40 is slidably connected to the base 30 so that the door panel 60 can be slidably connected to the door body 10; the assembly component 20 also includes a positioning workpiece 50 that is detachably matched with the base 30 and the sliding member 40, and the positioning workpiece 50 is used to assist in positioning the sliding member 40.

[0032] The positioning workpiece 50 includes a first pre-positioning structure 511, and the sliding member 40 includes a second pre-positioning structure 421 that cooperates with the first pre-positioning structure 511. After the positioning workpiece 50 and the sliding member 40 are pre-positioned and assembled, they are assembled and cooperated with the base 30 together to improve the accuracy of auxiliary positioning.

[0033] In a specific embodiment, the first pre-positioning structure 511 is a positioning column arranged toward the sliding member 40, and the second pre-positioning structure 421 is a positioning hole; or the first pre-positioning structure 511 is a positioning hole, and the second pre-positioning structure 421 is a positioning column arranged toward the positioning workpiece. The pre-positioning structure is provided as a positioning column and a positioning hole that cooperate with each other, which is simple to align and easy to install, and also convenient to pull out the positioning workpiece 50 from the sliding member 40 during subsequent disassembly.

[0034] Specifically, after the positioning workpiece 50 and the sliding member 40 are pre-positioned and assembled, the fixed connection between the two can be strengthened by a buckle structure, as shown in FIG. Figure 4 As shown, the positioning workpiece 50 is provided with an elastic buckle 512 near the first pre-positioning structure 511, and the sliding member 40 is provided with a buckle hole 422 that matches the elastic buckle 512. The elastic buckle 512 is combined with the buckle hole 422 to enhance the stability of the connection between the two.

[0035] Preferably, the door panel 60 includes a mounting surface 601 facing the door body, the sliding member 40 is fixed to the mounting surface 601 by a first fastener 71, and the base 30 is fixed to the side of the door body 10 by a second fastener 72. The first fastener 71 and the second fastener 72 can both be set as screws, and the screw includes a head and a rod. The positioning workpiece 50 is used to install the positioning sliding member 40 so that it has an accurate positional relationship relative to the base 30 to allow relative sliding and common rotation between the door body 10 and the door panel 60.

[0036] The base 30 is provided with a second screw hole 310, and the second screw hole 310 includes a mounting hole whose size is larger than the head of the screw and a fixing hole whose size is smaller than the head of the screw but larger than the rod of the screw. The mounting hole is a circular hole, and the fixing hole is a long hole and is connected to the mounting hole. Specifically, when installing the base 30, the second fastener 72 that comes with the foaming assembly of the door body 10 does not need to be removed. It is only necessary to rotate the second fastener 72 outward for a distance, align the mounting hole with the head of the screw and install it, and then move the base 30 along the direction of communication between the mounting hole and the fixing hole so that the second fastener 72 is assembled into the fixing hole, and then rotate and tighten the second fastener 72, so that the base 30 is attached to the side of the door body 10 and fixed.

[0037] Specifically, a long groove 311 may be further provided on the surface around the second screw hole 310 to form an anti-slip groove, and the anti-slip groove may cooperate with the second fastener 72 so that the second fastener 72 will not slip during assembly.

[0038] The base 30 is provided with a sliding groove 32 on one side close to the door panel 60 for the sliding member 40 to be installed and move therein. The sliding member 40 is in the shape of a longitudinal sheet as a whole, wherein the first end 41 is installed in the base 30, the main body 42 located in the middle is used to cooperate with the positioning workpiece 50 and be fixed to the mounting surface 601, and the second end 43 away from the first end 41 is formed as a rotatable cover body for subsequent covering of the main body 42.

[0039] The first fastener 71 is installed on the main body 42. The main body 42 is provided with a first screw hole 420 for installing the first fastener 71. The first screw hole 420 is a long hole. A positioning rib that cooperates with the rod of the first fastener 71 can be further provided in the first screw hole 420. The positioning rib can abut against the rod of the first fastener 71 to prevent the first fastener 71 from moving during installation, thereby playing a guiding and limiting role.

[0040] According to this embodiment, the second pre-positioning structure 421 and the first screw hole 420 are both formed in the main body 42 and can be formed as through holes arranged at intervals.

[0041] Preferably, the positioning workpiece 50 includes a positioning plate 51, a mounting plate 53 bent from one end of the positioning plate 51 toward the door body 10, and a reference plate 55 bent from the other end of the positioning plate 51 toward the door panel 60; Figure 3-4 As shown, the mounting plate 53 is mounted to the base 30, that is, with respect to the side of the door body 10, the reference plate 55 is attached to the side of the door panel 60. It can be seen that the positioning workpiece 50 can be used to accurately locate the distance between the side edges of the door body 10 and the door panel 60 and the distance between the door body 10 and the door panel 60 along the thickness direction, allowing the door body 10 and the door panel 60 to remain parallel without friction when being opened or closed at the maximum angle.

[0042] In this embodiment, the positioning plate 51 is predetermined to be located on the side of the sliding member 40 away from the mounting surface 601. The first pre-positioning structure 511 is provided on the side of the positioning plate 51 facing the sliding member 40 for pre-positioning and assembly with the sliding member 40. The elastic clip 512 is also provided on the side of the positioning plate 51 facing the sliding member 40 for clipping and fixing after assembly with the sliding member 40.

[0043] The positioning plate 51 is provided with a screw column 513 for accommodating a first fastener 71. The head of the first fastener 71 interferes with the inner wall surface of the screw column 513. The first fastener 71 can be pre-installed in the screw column 513 to prevent the first fastener 71 from falling off after being inserted into the screw column 513, thereby avoiding the need to search for accessories during installation and the loss of accessories.

[0044] The inner wall surface of the screw column 513 is provided with a limiting rib 514 that cooperates with the rod portion of the first fastener 71. When the first fastener 71 is inserted into the screw column 513, the limiting rib 514 can contact the thread of the first fastener 71, thereby limiting the movement of the first fastener 71.

[0045] Preferably, the sliding member 40 is provided with the first screw hole 420 at the position corresponding to the screw column 513, so that the first fastener 71 can be installed into the door panel 60. The limiting rib 514 is connected to the inner wall surface of the screw column 513 through a connecting strip, and the connecting strip can be broken so that the limiting rib 514 can be separated from the screw column 513. The first screw hole 420 is provided with an open groove surface 4201 facing the positioning workpiece 50 to accommodate the separated limiting rib 514. In this way, after the limiting rib 514 is broken, it can be stuck between the screw head and the first screw hole 420, without affecting the tightening of the screw.

[0046] Preferably, the outer wall of the screw column 513 is provided with a plurality of long grooves 515 along the axial direction, so that the outer wall is divided into a plurality of arc-shaped walls arranged at intervals along the circumferential direction, so as to provide elasticity for the first fastener 71 to be screwed into the door panel 60 .

[0047] The mounting plate 53 has a mounting space 530 on one side facing the door body 10 . The base 30 is located in the mounting space 530 and is snap-fastened to the mounting plate 53 . The reference plate 55 covers the side of the door panel 60 .

[0048] Reference Figure 6-9 As shown, the assembly process of the assembly component 20 will be briefly described below in conjunction with this embodiment:

[0049] First, fix the base 30 to the side of the door body 10 through the second fastener 72; pre-position and install the sliding member 40 and the positioning workpiece 50 through the first pre-positioning structure 511 and the second pre-positioning structure 421, and then fix them together through the elastic buckle 512 and the buckle hole 422. In this way, the sliding member 40 and the positioning workpiece 50 are assembled.

[0050] Next, the assembled sliding member 40 and the positioning workpiece 50 are assembled horizontally into the base 30 on the door body 10, wherein the first end 41 of the sliding member 40 is installed in the sliding groove 32 of the base 30 and slides relative to the base 30 in the sliding groove 32, and the mounting plate 53 of the positioning workpiece 50 is snap-fastened with the base 30, and the reference plate 55 is attached to the side of the door panel 60.

[0051] Secondly, a first fastener 71 is pre-installed in the positioning workpiece 50. The first fastener 71 is tightened with a screwdriver. The first fastener 71 is screwed into the door panel 60 along the screw column 513. The limiting rib 514 in the screw column 513 plays a limiting role. When the head of the first fastener 71 is pressed against the limiting rib 514, the limiting rib 514 is driven to break from the screw column 513 and move toward the sliding member 40 with the head of the first fastener 71. Fig. 9 The first fastener 71 will be screwed into the first screw hole 420 of the sliding member 40 to fit tightly, and the broken limiting rib 514 will be stuck in the open groove surface 4201, which will not affect the tightening of the first fastener 71. In this way, the sliding member 40 is fixed to the door panel 60 with the help of the positioning workpiece 50.

[0052] Then, a tilting force is applied to the positioning workpiece 50 to remove the positioning workpiece 50 from the base 30 and the slider 40 .

[0053] Finally, after the positioning workpiece 50 is removed from the base 30 and the sliding member 40, the second end 43 of the sliding member 40 is rotated toward one end of the base to be fixed to the main body 42 and cover a portion of the main body 42, thereby covering the first screw hole 420 and the first fastener 71, which serves as an aesthetic decoration; the door body assembly includes a base cover 33. After the positioning workpiece 50 is removed from the base 30 and the sliding member 40, the base cover 33 is fixedly assembled with the base 30 and covers the base 30, which serves as an aesthetic decoration. The base cover 33 is formed integrally with the base 30 or separately.

[0054] The cover of the sliding member 40 is provided with a first groove, and the main body is provided with a second groove corresponding to the first groove. The first groove and the second groove form an operating portion 431 for operation to facilitate opening the cover.

[0055] The beneficial effects of the present invention are as follows: the sliding member 40 and the positioning workpiece 50 are pre-assembled and fixed by means of a pre-positioning structure and a snap-fit ​​structure, thereby improving the accuracy of positioning; a first fastener 71 is pre-installed in the positioning workpiece 50, and a limiting rib 514 is provided to limit the first fastener 71 and prevent it from moving; an open groove surface 4201 is provided in the first screw hole 420 to accommodate a broken limiting rib 514, without affecting the tightening of the first fastener 71.
