[0087] It should be noted that Figure 1In order to schematically show the relative positions of the first door body 100, the first adjusting member 300, the second door body 200 and the second adjusting member 400, the first adjusting member 300 and the second adjusting member 400 are shown in perspective, so that Figure 1 It appears that the first adjusting member 300 and the second adjusting member 400 are located on the outside of the second door body 200 , but in fact, the first adjusting member 300 and the second adjusting member 400 are located on the side of the second door body 200 facing the first door body 100 , that is, between the side of the second door body 200 facing the first door body 100 and the installation surface 101 of the first door body 100 .

[0088] The door assembly of this embodiment can be applied to household appliances. Specifically, the first door body 100 can be the door body of a refrigeration appliance and the second door body 200 can be the cabinet door of a cabinet, or the first door body 100 can be the cabinet door of a cabinet and the second door body 200 can be the door body of a refrigeration appliance. The refrigeration appliance can be a refrigeration or freezing appliance, specifically a refrigerator, etc. Usually, one of the first door body 100 and the second door body 200 is assembled and fixed with the corresponding device body, and the other is fixed on the one, and the other corresponds to the corresponding device body but is not connected. Specifically, this embodiment is mainly described by taking the first door body 100 as an example in which the second door body 200 is fixedly assembled to the first door body 100 after being assembled with the corresponding device body. The first door body 100 can be assembled with the corresponding device body into a household appliance and stored, transported or sold as a complete piece of furniture, or it can be stored, transported or sold independently. When one of the first door body 100 and the second door body 200 that usually cooperate with each other corresponds to a household appliance that needs to be sealed, the first door body 100 can be set as the door body of the household appliance that needs to be sealed, and the first door body 100 and the equipment body of the household appliance can be assembled into an integral piece of furniture. For example, in a cabinet and a built-in refrigerator, the first door body 100 is usually a refrigerator door body 10, and the refrigerator is transported and sold as a conventional complete refrigerator.

[0089] It should also be noted that the second door body 200 can be fixed to the first door body 100, the second door body 200 is located at the opening of the accommodating cavity of the corresponding device body, and the second door body 200 can be connected to the corresponding device body or not. Among them, when the second door body 200 is connected to the corresponding device body, the connection between the second door body 200 and its corresponding device should enable the second door body 200 to be opened or closed synchronously with the first door body 100. For example, the device body corresponding to the first door body 100 is a refrigerator body, the first door body 100 is assembled and connected with the refrigerator body to form a complete refrigerator, the device body corresponding to the second door body 200 is a cabinet, the second door body 200 is located at the opening of the cabinet, the cabinet door can be fixed to the refrigerator door body 10 and is not connected to the cabinet; the cabinet door can also be fixed to the refrigerator door body 10, and an adaptive flexible connection is established between the cabinet and the cabinet, so that the cabinet door and the refrigerator door body 10 are opened or closed synchronously.

[0090] In this embodiment, the first adjusting member 300 and the second adjusting member 400 can be used as accessories of the first door body 100, and can be stored or transported together with the first door body 100. When the first door body 100 is transported to the user side, they are assembled to the corresponding first door body 100 and second door body 200. In other words, during the transportation of the door body assembly or the preparation of the door body assembly, the first adjusting member 300 and the second adjusting member 400 can be placed in the form of parts and accessories. When the door body assembly is transported to the installation position required by the user, for example, when the user purchases a refrigerator and the refrigerator is transported to the user's home, the first adjusting member 300 is installed on the first door body 100, and the second adjusting member 400 is installed on the second door body 200, and the assembly of the second door body 200 to the first door body 100 is achieved through the first adjusting member 300 and the second adjusting member 400.

[0091] Of course, the first adjusting member 300 can also be assembled to the first door body 100 during the processing and preparation of the first door body 100, that is, the second adjusting member 400 is transported as an accessory in the form of a part, so that when assembling on the user side, it is only necessary to assemble the second adjusting member 400 to the second door body 200, and then the first adjusting member 300 and the second adjusting member 400 are used to realize the assembly of the second door body 200 to the first door body 100. In some cases, the second adjusting member 400 can also be temporarily assembled to the first adjusting member 300. When assembling on the user side, the second adjusting member 400 can be disassembled from the first adjusting member 300, and then the second adjusting member 400 is assembled to the second door body 200, and then the second door body 200 is assembled to the first door body 100 through the first adjusting member 300 and the second adjusting member 400. In some cases, the second door body 200 and the second door body 200 may also be prepared by a manufacturer. For example, a built-in refrigerator and its matching cabinet are a complete household appliance. In this case, the first adjusting member 300 and the second adjusting member 400 can be transported in the form of parts, or the first adjusting member 300 can be pre-installed on the first door body 100, and the second adjusting member 400 can be pre-installed on the second door body 200. In this way, when assembling on the user side, when assembling the first door body 100 and the second door body 200, the first adjusting member 300 and the second adjusting member 400 can be directly adjusted as needed.

[0092] It should also be noted that the second adjusting member 400 can also be pre-assembled to the first adjusting member 300, and then the second adjusting member 400 can be installed on the second door body 200. In this case, the process of assembling the second adjusting member 400 to the second door body 200 may be more time-consuming. Although the assembly of the first door body 100 and the second door body 200 can also be achieved, it may be more time-consuming and labor-intensive. The present embodiment provides protection for the state of whether the first adjusting member 300 is installed to the first door body 100, the state of whether the second adjusting member 400 is installed to the second door body 200, and the state of whether the first adjusting member 300 and the second adjusting member 400 have been assembled. In other words, the first adjusting member 300 and the second adjusting member 400 may have various states before and after assembly on the user side, but as long as the first adjusting member 300 can be installed to the first door body 100 and cooperate with the second adjusting member 400 to achieve the function to be achieved in the present embodiment, and the second adjusting member 400 can be installed to the second door body 200 and cooperate with the first adjusting member 300 to achieve the function to be achieved in the present embodiment, they are all within the protection scope of the present embodiment.

[0093] The first direction and the second direction are both parallel to the mounting surface 101, and the first direction is perpendicular to the second direction. Due to actual errors and other reasons, the first direction and the second direction may be approximately parallel to the mounting surface 101, and the first direction and the second direction may be approximately perpendicular, that is, this embodiment does not make strict requirements for perpendicularity and parallelism, and it is sufficient to be close to parallelism or close to perpendicularity. For example, if the angle between the first direction and the second direction is between 85-95 degrees, it can be considered that the first direction and the second direction are perpendicular to each other.

[0094] Specifically, the first direction may be the width direction X of the first door body 100, and correspondingly, the second direction is the height direction Y of the first door body 100; the first direction may also be the height direction Y of the first door body 100, and correspondingly, the second direction is the width direction X of the first door body 100. Among them, the width direction X of the first door body 100 is perpendicular to the height direction Y of the first door body 100, and the width direction X of the first door body 100 and the height direction Y of the first door body 100 are both parallel to the installation surface 101. It can be understood that the width direction X of the first door body 100 and the height direction Y of the first door body 100 are described based on the actual application state of the first door body 100, and can also be understood as a reference description based on the example of the first door body 100 being installed on the corresponding equipment body. For example, the first door body 100 is a door body of a refrigeration appliance, for example, a refrigerator door body 10, a height direction Y of the first door body 100 is consistent with a height direction Y of the refrigerator (the height direction Y of the refrigerator can be understood with reference to the vertical direction), and a width direction X of the first door body 100 is consistent with a width direction X of the refrigerator (the width direction X of the refrigerator is also the left and right direction of the user when the user faces the refrigerator).

[0095] The mounting surface 101 is usually the largest panel surface of the first door body 100 and is the surface on which the first door body 100 can be assembled with the second door body 200, that is, the surface of the first door body 100 that faces the second door body 200. For example, when the first door body 100 is the door body of a refrigeration appliance and the second door body 200 is a cabinet door, the door body of the refrigeration appliance is usually located on the inner side of the cabinet door, and the mounting surface 101 of the first door body 100 can be the outer side of the first door body 100; for another example, when the second door body 200 is the door body of a refrigeration appliance and the first door body 100 is a cabinet door, the door body of the refrigeration appliance is usually located on the inner side of the cabinet door, and the mounting surface 101 of the first door body 100 can be the inner side of the first door body 100.

[0096] The second adjusting member 400 is connected to the first adjusting member 300 through the adjusting portion 420. After the adjusting portion 420 is connected to the first adjusting member 300, the adjusting portion 420 and the first adjusting member 300 can retain the degree of freedom in the first direction, so that the adjusting portion 420 and the first adjusting member 300 can slide relative to each other in the first direction, so that the relative position of the second adjusting member 400 and the first adjusting member 300 along the first direction can be relatively adjusted. The second adjusting member 400 also cooperates with the limiting portion 310 through the adjusting portion 420 to position or limit the relative movement of the second adjusting member 400 and the first adjusting member 300 in the second direction. In other words, after the adjusting portion 420 and the limiting portion 310 are limitedly matched, the relative position of the second adjusting member 400 and the first adjusting member 300 in the first direction can be positioned, so that during the sliding process of the second adjusting member 400 and the first adjusting member 300 along the first direction, the second adjusting member 400 can be relatively fixed with the position of the first adjusting member 300 in the second direction.

[0097] The first adjusting member 300 may be a slide rail disposed on the mounting surface 101, and the second adjusting member 400 may be a slider. Specifically, the first direction is the width direction X of the first door body 100, and the second direction is the height direction Y of the second door body 200. The slide rail may be a bar-shaped block structure, such as a bar block with a rectangular cross section, the length direction of the bar block is arranged along the width direction X of the first door body 100, the upper surface of the slide rail may serve as a limiter 310, and the slider may slidably abut against the upper surface of the bar block. In the case where the slide rail is a bar-shaped block structure, a slide groove or a slide hole is provided on the slider, and the slide rail is sleeved in the slide groove or the slide hole, so that the slider is sleeved on the slide rail to abut against the slide rail and can slide along the width direction X of the first door body 100. A slide groove 320 may also be provided on the slide rail, and the side wall of the slide groove 320 may serve as a limiter 310, and the slider may be slidably arranged in the slide groove 320 and abut against the groove wall of the slide groove 320. In addition, it should be noted that in some possible implementations, the slider can be rotatably arranged on the slide rail, so that the slider can slide relative to the slide rail in a rolling manner. For example, the slider can be a roller, and the roller abuts against the slide groove 320 of the slide rail. The roller can roll relative to the slide rail in the annular groove to achieve movement of the roller along the width direction X of the first door body 100, that is, to achieve sliding cooperation between the second adjustment member 400 and the first adjustment member 300 along the width direction X.

[0098] In some implementations, the fixing portion 410 of the second adjusting member 400 can be first assembled to the second door body 200 through the first position 411, and then the second adjusting member 400 is assembled with the first adjusting member 300. The first position 411 of the fixing portion 410 can be understood as the initial positioning assembly position of the second adjusting member 400 for connecting with the second door body 200. Since the second adjusting member 400 needs to be connected with the second door body 200, the second adjusting member 400 must have a position for connecting with the second door body 200, and the second door body 200 also has a position for connecting with the second adjusting member 400. In order to facilitate the adjustment of the relative positions of the first door body 100 and the second door body 200 in the first direction and the second direction through the first adjusting member 300 and the second adjusting member 400, a suitable position can be selected on the second adjusting member 400, which is defined as the first position 411 for connecting with the second door body 200. After the second adjusting member 400 is installed on the second door body 200, the position of the first position 411 in the first direction and the second direction of the second door body 200 will not change, and the second adjusting member 400 is always connected to the second door body 200 at the same position of the first position 411 (that is, the position of the second door body 200 used to connect the second adjusting member 400 will usually not change). In this way, since the position of the first position 411 and the second door body 200 in the first direction and the second direction are determined, and the first adjusting member 300 is installed on the first door body 100, the position of the first adjusting member 300 and the first door body 100 in which it is located in the first direction and the second direction are determined. In this way, by adjusting the relative position of the adjusting part 420 and the first adjusting member 300 in the first direction and the second direction, the corresponding positions of the first door body 100 and the second door body 200 can be adjusted.

[0099] Specifically, since the adjusting portion 420 of the second adjusting member 400 can be slidably matched with the second adjusting member 400 in the width direction X, the relative position adjustment of the first door body 100 and the second door body 200 in the first direction can be achieved by sliding the first adjusting member 300 relative to the second adjusting member 400 or by sliding the second adjusting member 400 relative to the first adjusting member 300. Since the first position 411 of the fixing portion 410 and the position of the second door body 200 are relatively fixed, the relative position of the first position 411 and the first adjusting member in the second direction can be adjusted by adjusting the length between the adjusting portion 420 and the first position 411 along the second direction, thereby achieving the relative position adjustment of the first door body 100 and the second door body 200 in the second direction.

[0100] The dimension between the adjusting portion 420 and the first position 411 along the second direction can be understood as the distance between the position where the adjusting portion 420 is connected to the first adjusting member 300 and the first position 411 along the second direction. Figures 2 to 4 as well as Figures 7 to 12As shown, one end of the adjusting portion 420 away from the fixing portion 410 is used to abut against the limiting portion 310. For the convenience of description, the end of the adjusting portion 420 used to abut against the limiting portion 310 is defined as an abutting end 422. The abutting end 422 is the position abuttingly connected to the first adjusting member 300 (i.e., the limiting portion 310). Accordingly, the dimension along the second direction between the first position 411 and the adjusting portion 420 can be understood as the distance between the abutting end 422 and the first position 411 along the second direction.

[0101] It should be noted that the dimension between the adjusting portion 420 and the first position 411 along the second direction is based on the second adjusting member 400 being installed on the second door body 200 or the second adjusting member 400 being assembled with the first adjusting member 300. When the second adjusting member 400 has not yet been assembled to the second door body 200 or the first adjusting member 300, the adjusting portion 420 only needs to be adjustable in dimension with respect to the first position 411 in one direction. Based on reasonable assembly, the dimension adjustable direction of the adjusting portion 420 corresponds to the second direction, and the dimension adjustable in the second direction between the adjusting portion 420 and the first position 411 can be realized.

[0102] When the door assembly is actually assembled, the first door 100 and the second door 200 can be assembled, and then the relative positions of the first door 100 and the second door 200 in the first direction and the second direction can be adjusted by adjusting the first adjusting member 300 and the second adjusting member 400. When the door assembly is actually assembled, the size between the adjusting portion 420 of the second adjusting member 400 and the first position 411 can be adjusted as needed, so that the first door 100 and the second door 200 can first meet the adjustment and positioning requirements in the second direction, and then the second adjusting member 400 and the first adjusting member 300 are assembled in coordination, and the second adjusting member 400 and the first adjusting member 300 slide relative to each other along the first direction to adjust the positions of the second adjusting member 400 and the first adjusting member 300 in the first direction, thereby meeting the adjustment and positioning requirements of the first door 100 and the second door 200 in the first direction. In this embodiment, unless otherwise specified, it can be understood that the relative adjustment of the first door 100 and the second door 200 is achieved in the latter manner.

[0103] The door body assembly according to the present application can be applied to household appliances. Specifically, the first door body 100 can be the door body of a refrigeration appliance (such as a refrigerator) and the second door body 200 can be the cabinet door of a cupboard, or the first door body 100 can be the cabinet door of a cupboard and the second door body 200 can be the door body of a refrigeration appliance. By using the door body assembly of the present application, the difficulty of assembling the refrigeration appliance and the cupboard door can be reduced, and the assembly efficiency can be improved.

[0104] Reference Figures 1 to 9As shown, in some implementations (the following embodiments mainly use this implementation as an example for related description), the first direction is the width direction X, and the second direction is the height direction Y. The door assembly of this embodiment can achieve bidirectional adjustment in the width direction X and the height direction Y through the first adjustment member 300 and the second adjustment member 400, and the component structure is simple and easy to operate. Specifically, by setting the first adjusting member 300 on the installation surface 101 of the first door body 100, the second adjusting member 400 can be installed on the second door body 200 when the second door body 200 is assembled with the first door body 100. In this way, after the second adjusting member 400 cooperates with the first adjusting member 300, the second adjusting member 400 and the first adjusting member 300 can be made to slide relative to each other, so as to adjust the relative position of the first door body 100 and the second door body 200 along the width direction X; by adjusting the relative position between the first position 411 and the adjusting part 420 along the height direction Y of the first door body 100, the position adjustment of the first door body 100 relative to the second door body 200 along the height direction Y can also be realized through the cooperation of the second adjusting member 400 and the first adjusting member 300. At the same time, during the assembly process of the second door body 200 and the first door body 100, the second adjusting member 400 can slide with the limiting portion 310 of the first adjusting member 300, and the limiting portion 310 of the first adjusting member 300 abuts against the second adjusting member 400, so that the first door body 100 can support the second door body 200 through the first adjusting member 300 and the second adjusting member 400. During the positioning and adjustment process of the second door body 200 and the first door body 100, the assemblers do not need to frequently carry or lift the door bodies, which is more labor-saving, reduces the operating difficulty, and improves the assembly efficiency.

[0105] According to some embodiments of the present application, optionally, the adjustment portion 420 is detachably connected to the first adjustment member 300 .

[0106] It is understandable that the first adjusting member 300 and the adjusting portion 420 are detachably connected, so that the first adjusting member 300 and the second adjusting member 400 can be detachably connected, so that the second door body 200 is temporarily assembled to the first door body 100 only through the second adjusting member 400 and the first adjusting member 300, and the second door body 200 and the first door body 100 are not adjusted in place in the second direction (in the height direction Y in this embodiment), the second door body 200 can also be disassembled from the first door body 100, and then the adjusting portion 420 of the second adjusting member 400 provided on the second door body 200 is adjusted so that the size between the adjusting portion 420 and the first position 411 along the second direction can be adjusted. The size adjustment between the adjusting portion 420 of the second adjusting member 400 and the first position 411 along the second direction can be adjusted when the second door body 200 is separated from the first door body 100, and the operation is more convenient.

[0107] Specifically, the adjusting portion 420 can slide from one end of the limiting portion 310 along the first direction to connect with or detach from the first adjusting member 300. Figures 7 to 9 As shown, the second adjusting member 400 can slide from one end of the limiting portion 310 along the width direction X to be connected with the first adjusting member 300 and abut against the limiting portion 310 or slide to be separated from the first adjusting member 300 .

[0108] Among them, refer to Figures 7 to 9 As shown, one end of the limiting portion 310 in the width direction X refers to roughly the left end or the right end of the limiting portion 310, that is, one end of the two ends that are separated from each other in the width direction X. The second adjusting member 400 can slide from one end of the two ends of the limiting portion 310 in the width direction X to the first adjusting member 300 or detach from the first adjusting member 300.

[0109] Specifically, in one implementation, Figure 7 and Figure 8 As shown, the limiting portion 310 passes through both ends of the mounting surface 101 along the width direction X of the mounting surface 101. In this way, since there are no stoppers at both ends of the limiting portion 310 along the width direction X, the second adjusting member 400 can slide into the limiting portion 310 of the first adjusting member 300 from any end of the limiting portion 310. Figure 7 and Figure 8 As shown, the first adjusting member 300 includes a slide groove 320, and the top side wall (first sub-wall 331) or the bottom side wall (second sub-wall 332) of the slide groove 320 can be used as a limiting portion 310. The slide groove 320 passes through both ends of the mounting surface 101 along the width direction X of the mounting surface 101 (that is, both ends of the first door body 100 along the width direction X). The second adjusting member 400 can slide into the slide groove 320 from one end of the slide groove 320, so that the second adjusting member 400 is connected to the first adjusting member 300 and abuts against the limiting portion 310. The second adjusting member 400 can also slide out of the slide groove 320 from one end of the slide groove 320, so that the second adjusting member 400 is separated from the first adjusting member 300.

[0110] It should be noted that, in the implementation method of the limiting portion 310, only one end of the limiting portion 310 may be aligned and correspond to one end of the width direction X of the mounting surface 101, so that the second adjusting member 400 can be connected or disconnected with the first adjusting member 300 through the end of the limiting portion 310 aligned with the mounting portion.

[0111] In another implementation, Fig. 9As shown, the limiting portion 310 is located inside the width direction X of the installation surface 101, and an avoidance notch 335 can be set at one end or both ends of the limiting portion 310 in the width direction X, so that the second adjusting member 400 can slide through the avoidance notch 335 to connect with the first adjusting member 300, or slide to the avoidance notch 335 and can be detached from the first adjusting member 300. In this implementation, the first adjusting member 300 and the limiting portion 310 can be set as multiple discontinuous sections in the width direction X. When the first door body 100 is sequentially equipped with multiple second adjusting members 400 along the width direction X, each second adjusting member 400 can correspond to an avoidance notch 335, so that the second adjusting member 400 does not need to slide from one end of the installation surface 101 in the width direction X to the other end, but can slide from the corresponding avoidance notch 335 to the first adjusting member 300, which can shorten the sliding stroke of the second adjusting member 400 along the width direction X and improve the assembly efficiency.

[0112] In this embodiment, during the process of assembling the second door body 200 to the first door body 100, the second adjusting member 400 can be connected to the first adjusting member 300 by sliding along the width direction X, and assembled until it abuts against the limiting portion 310, which is convenient and quick to operate. After the first door body 100 and the second door body 200 are initially assembled, if it is found that the first door body 100 does not match the second door body 200 in the height direction Y, the second adjusting member 400 can be slid from one end of the first adjusting member 300 to be disconnected from the first adjusting member 300, so that the second door body 200 can be easily removed from the first door body 100. In this way, after the initial preliminary assembly of the second door body 200 and the first door body 100, if the positioning of the two along the height direction Y is not appropriate, the deviation of the first door body 100 and the second door body 200 in the height direction Y can be measured in the initial preliminary assembly state, and then the second door body 200 can be removed from the first door body 100. Since the relative height adjustment of the first door body 100 and the second door body 200 can be achieved by the corresponding adjustment of the first adjustment member 300 and / or the second adjustment member 400 on the corresponding door body, the first adjustment member 300 and the second adjustment member 400 can be adjusted accordingly according to the deviation. After the corresponding height positioning adjustment is achieved, the second door body 200 can be slid onto the first adjustment member 300 through the second adjustment member 400. Due to the sliding method, it is relatively convenient to disassemble and assemble the second door body 200 to the first door body 100, and since the first adjusting member 300 and / or the second adjusting member 400 can adjust the height of the second door body 200 relative to the first door body 100, it can be done when the first door body 100 and the second door body 200 are separated, the first door body 100 and the second door body 200 can be assembled after adjusting the height in a separated manner, which is easy to operate and saves time and effort.

[0113] According to some embodiments of the present application, Figure 1 , Figures 3 to 9 As shown, optionally, in some embodiments, the first adjusting member 300 includes a slide groove 320 , the slide groove 320 includes a side wall extending along the width direction X, the side wall forms a limiting portion 310 , and the second adjusting member 400 is slidably disposed in the slide groove 320 .

[0114] The slide groove 320 may be formed by partially recessing the mounting surface 101 of the first door body 100. Alternatively, a track block 340 may be provided on the first door body 100, the track block 340 extending along the width direction X, and having the slide groove 320 on the track block 340. The track block 340 may be integrally constructed with the first door body 100, or may be connected to the mounting surface 101 of the first door body 100 by means of a connecting member such as screws, welding, etc. Figure 4 As shown, the track block 340 can be installed on the installation surface 101 of the first door body 100 in a protruding manner, that is, the track block 340 can be set on the surface of the installation surface 101 and fixed on the installation surface 101. Figure 3 As shown, the track block 340 can also be formed in a recessed form on the mounting surface 101 of the first door body 100, that is, a mounting groove 350 can be provided on the first door body 100, the mounting groove 350 is recessed relative to the mounting surface 101, and the track block 340 has a slide groove 320, and the track block 340 is partially or completely embedded in the mounting groove 350.

[0115] The installation groove 350 is equivalent to a groove structure formed by a local depression of the installation surface 101, and the opening of the installation groove 350 faces the installation surface 101. On the first door body 100, the installation groove 350 is depressed toward the side away from the installation surface 101. The installation groove 350 can be a groove formed by removing part of the material on the first door body 100.

[0116] like Figure 3 , Figure 4 and Figure 6 As shown, the slide groove 320 can be a groove with a U-shaped cross-section. Specifically, the side wall of the slide groove 320 can include a first sub-wall 331 and a second sub-wall 332, both of which extend along the width direction X. The first sub-wall 331 and the second sub-wall 332 are relatively spaced apart, wherein the first sub-wall 331 can be located above the second sub-wall 332, and the second adjustment member 400 can be slidably disposed between the first sub-wall 331 and the second sub-wall 332.

[0117] The first sub-wall 331 or the second sub-wall 332 can be used as the limiting portion 310. Specifically, the side of the second sub-wall 332 facing the inside of the slide slot 320, that is, the side facing the side where the first sub-wall 331 is located, can be used as the limiting portion 310; the side of the first sub-wall 331 facing the inside of the slide slot 320, that is, the side facing the side where the second sub-wall 332 is located, can be used as the limiting portion 310 for cooperating with the second adjusting member 400. In the subsequent description of this embodiment, the first sub-wall 331 is used as the limiting portion 310, which can be understood by referring to the side of the first sub-wall 331 facing the inside of the slide slot 320, that is, the lower surface of the first sub-wall 331 is used as the limiting portion 310; the second sub-wall 332 is used as the limiting portion 310, which can be understood by referring to the side of the second sub-wall 332 facing the inside of the slide slot 320, that is, the upper surface of the second sub-wall 332 is used as the limiting portion 310.

[0118] Depending on whether the first door body 100 is a cabinet panel 20 or a door body of a refrigeration appliance, one of the first sub-wall 331 and the second sub-wall 332 can be adaptively selected as the limiting portion 310. Figure 4 As shown, in some implementations, the first door body 100 is an assembled door body, for example, the first door body 100 is an assembled refrigerator door body 10, in which case the first door body 100 is equivalent to being fixed, and the second door body 200 needs to be assembled to the first door body 100. During the process of assembling the second door body 200 to the first door body 100, usually only the second door body 200 is movable, that is, the position of the second door body 200 relative to the first door body 100 can be adjusted only by relying on the movement of the second door body 200; in this implementation, after the second adjusting member 400 is assembled to the second door body 200, during the process of assembling the second door body 200 and the first door body 100, the second adjusting member 400 can be moved. The second adjusting member 400 is in contact with the second sub-wall 332 (i.e., the bottom side wall of the slide groove 320). The second sub-wall 332 supports the second adjusting member 400 in the height direction Y (vertical direction) and limits the second adjusting member 400 from moving downward in the height direction Y. In this way, due to the gravity of the second door body 200, the second adjusting member 400 can continue to maintain contact with the second sub-wall 332. The relative position of the second adjusting member 400 and the second sub-wall 332 in the height direction Y is fixed. The corresponding relative position of the second adjusting member 400 and the first adjusting member 300 in the height direction Y is fixed, so that the relative position of the second door body 200 relative to the first door body 100 in the height direction Y is fixed. Figure 3As shown, in other implementations, the second door body 200 is an assembled door body, for example, the second door body 200 is an assembled refrigerator door body 10, in which case the second door body 200 is equivalent to being fixed, and the first door body 100 needs to be assembled to the second door body 200. During the process of assembling the first door body 100 to the second door body 200, usually only the first door body 100 is movable, that is, the position adjustment of the second door body 200 and the second door body 200 is achieved only by the movement of the first door body 100; in this implementation, the second adjusting member 400 is first assembled to the second door body 200, and then the first door body 100 is assembled to the second door body 200, and the first door body 100 is assembled to the second door body 200. During the assembly process with the second door body 200, the first sub-wall 331 (that is, the top side wall of the slide groove 320) abuts against the top of the second adjusting member 400, and the second adjusting member 400 supports the first door body 100. The second adjusting member 400 supports the first sub-wall 331 in the height direction Y (vertical direction) and limits the downward movement of the first sub-wall 331 in the height direction Y. In this way, under the action of gravity of the first door body 100, the first sub-wall 331 is always abutted against the second adjusting member 400, and the relative positions of the first adjusting member 300 and the second adjusting member 400 in the height direction Y are fixed, so that the relative positions of the first door body 100 and the second door body 200 in the height direction Y are fixed.

[0119] In some embodiments, the side wall is also connected to a stop portion 333, which is opposite to and spaced from the bottom wall 334 of the slide groove 320, forming a limiting gap 336 between the stop portion 333 and the bottom wall 334 of the slide groove 320, and the end of the second adjusting member 400 along the height direction Y is used to be set in the limiting gap 336.

[0120] The bottom wall 334 of the slide slot 320 is connected to one end of the side wall of the slide slot 320, and the bottom wall 334 is opposite to the opening of the slide slot 320. Figures 3 to 6 As shown, one end of the first sub-wall 331 away from the bottom wall 334 and one end of the second sub-wall 332 away from the bottom wall 334 are both provided with a stopper 333, the stopper 333 connected to the first sub-wall 331 extends toward the side where the second sub-wall 332 is located, and the stopper 333 connected to the second sub-wall 332 extends toward the side where the first sub-wall 331 is located, and a limited gap 336 is formed between any one of the stoppers 333 and the bottom wall 334. When the second adjusting member 400 is assembled into the slide slot 320, the two ends of the second adjusting member 400 along the height direction Y can be respectively limited in the corresponding limited gaps 336.

[0121] It is understandable that, by providing the stopper 333 , the stability of the second adjusting member 400 when sliding in the slide groove 320 can be improved, and the possibility of the second adjusting member 400 being separated from the slide groove 320 during the sliding process can be reduced.

[0122] In the solution corresponding to the stopper 333 provided on the side wall, the stopper 333 can pass through both ends of the first door body 100 along the width direction X, so that the second adjusting member 400 can slide into the slide groove 320 from the end of the stopper 333 in the width direction X and be stopped by the stopper 333. The stopper 333 can also be provided at a local position of the first door body 100 in the width direction X, that is, Fig. 9 As shown, a relief notch 335 is provided on the side wall, and the relief notch 335 is provided at one or both ends of the stopper 333 along the width direction X, and the relief notch 335 is used for the second adjustment part 420 to be inserted into the limiting gap 336. Fig. 9 As shown, the first sub-wall 331 and the second sub-wall 332 may be both provided with an avoidance gap 335, that is, the first sub-wall 331 and the second sub-wall 332 may both have a position where the stop portion 333 is not provided, and the avoidance gap 335 is formed at this position, and the avoidance gap 335 of the first sub-wall 331 and the avoidance gap 335 of the second sub-wall 332 may be aligned to facilitate the insertion of the second adjustment member 400 from the avoidance gap 335 into the position of the slide groove 320 having the stop portion 333.

[0123] It should be noted that, in some cases, the avoidance gap 335 may be provided only on the first sub-wall 331 or the second sub-wall 332 .

[0124] In some embodiments, there are multiple second adjustment members 400, any one of which can be detachably connected to the second door body 200, and at least two of the multiple second adjustment members 400 have different adjustable ranges along the second direction, wherein the adjustable range is the adjustable size range between the adjustment portion 420 and the corresponding first position 411 along the second direction.

[0125] The number of the second adjusting members 400 may be two or more, and some of the second adjusting members 400 may be spare parts, that is, according to actual assembly requirements, the required number of second adjusting members 400 may be selected from the plurality of second adjusting members 400 and installed on the second door body 200, and the remaining second adjusting members 400 may not be assembled to the second door body 200. Along the second direction, the adjustable ranges of the plurality of second adjusting members 400 may all be different, or the adjustable ranges of some of the second adjusting members 400 may be the same, and the adjustable ranges of some of the second adjusting members 400 may be different.

[0126] The first position 411 corresponding to the adjustment portion 420 is the first position 411 of the second adjustment member 400 where the adjustment portion 420 is located, that is, the adjustable range of each second adjustment member 400 is the adjustable range along the second direction between the adjustment portion 420 and the first position 411 of the same second adjustment member 400.

[0127] The adjustable ranges of at least two second adjusting members 400 are different, which can be understood as the size adjustment values ​​of at least two second adjusting members 400 do not overlap. Taking the adjustable ranges of the two second adjusting members 400 as an example, in the two second adjusting members 400, the size between the node and the first position 411 along the second direction does not overlap, for example, along the second direction, the adjustable size between the adjusting portion 420 of one second adjusting member 400 and the first position 411 is 0.2 mm, 0.4 mm, 0.6 mm, and the adjustable size between the adjusting portion 420 of the other second adjusting member 400 and the first position 411 is 0.1 mm, 0.3 mm, 0.5 mm; for another example, the adjustable size between the adjusting portion 420 of one second adjusting member 400 and the first position 411 can be infinitely adjusted between 0.2 mm and 1 mm, and the adjustable size between the adjusting portion 420 of the other second adjusting member 400 and the first position 411 can be infinitely adjusted between 1.1 mm and 2 mm.

[0128] Optionally, in some embodiments, after the size between the adjusting portion 420 and the first position 411 along the second direction is adjusted appropriately, the fixing portion 410 may be further fixed. Figures 7 to 12 and Fig.18 As shown, a fixing hole 415 can be provided on the fixing part 410, and the door body assembly also includes a fastener, which is used to pass through the fixing hole 415 to fix the second adjusting member 400 to the second door body 200. Among them, one or more fixing holes 415 can be provided. When there are multiple fixing holes 415, multiple fixing holes 415 can be arranged at intervals along the circumference of the fixing part 410. The fastener can be a bolt or a screw, and the fastener passes through the fixing hole 415 to lock the fixing part 410 on the second door body 200, so that the fixing part 410 is relatively fixed to the second door body 200. For another example, Fig.16 and Fig.17 As shown, a snap-fit ​​structure 416 is provided on the fixing portion 410, and the snap-fit ​​structure 416 is used to snap the fixing portion 410 to the second door body 200, wherein a first base 500 may be provided on the second door body 200, and the first base 500 is snap-fitted to the snap-fit ​​structure 416 on the fixing portion 410, so that the second adjustment member is snap-fitted to the second door body 200.

[0129] It should be noted that the fixing portion 410 may have a positioning hole 413 corresponding to the first position 411 . In other words, the positioning hole 413 forms the first position 411 , and the fixing portion 410 may be preliminarily assembled with the second door body 200 through the positioning hole 413 .

[0130] The second adjusting member 400 of the door assembly can have various specific structural forms. Several specific implementation structures of the second adjusting member 400 are given below.

[0131] Implementation Method 1

[0132] like Figures 7 to 12 As shown, the second adjusting member 400 includes a fixed portion 410 and an adjusting portion 420 that are fixedly connected. The fixed portion 410 and the adjusting portion 420 can be fixedly connected by welding or the like, or can be an integrally formed structure. The fixed portion 410 has a first axis 412 at a first position 411, and the first axis 412 is perpendicular to the mounting surface 101. The fixed portion 410 can rotate around the first axis 412. The adjusting portion 420 is arranged on the circumferential side wall of the fixed portion 410. Along the rotation direction of the fixed portion 410, the adjusting portion 420 has at least two adjusting positions 421. Along the direction perpendicular to the first axis 412, the shortest distance between the adjusting position 421 and the first axis 412 is the first distance A. The first distances A between the at least two adjusting positions 421 and the first axis 412 are different. Under the action of the fixed portion 410 rotating around the first axis 412, any one of the adjusting positions 421 can be adjusted to be arranged along the second direction.

[0133] The adjustment position 421 can be understood with reference to the abutting end 422. Specifically, the adjustment position 421 is a position for abutting against the limiting portion 310. The adjustment position 421 can be a point or a surface. Usually, the adjustment portion 420 can be formed into an abutting position by a point or a surface on the end surface of the fixing portion 410 away from the adjustment portion 420. The first distance A can be understood as the distance between the abutting end 422 and the first axis 412 (the center point of the fixing portion 410) along the radial direction of the fixing portion 410. In other words, the distance between the point or surface of the abutting end 422 farthest from the first axis 412 and the center point of the fixing portion 410 along the radial direction of the fixing portion 410.

[0134] During the assembly of the second door body 200 and the first door body 100, the fixing part 410 can be first installed on the second door body 200 in a rotatable manner. When the fixing part 410 is on the second door body 200, it can rotate around the first axis 412. By rotating the fixing part 410, the adjustment position 421 of the adjustment part 420 can be adjusted so that the adjustment position 421 of the appropriate length (size) corresponds to the second direction, thereby achieving the purpose of adjusting the size between the adjustment part 420 and the first position 411 along the second direction.

[0135] In some possible solutions, the adjustment part can be an eccentric wheel formed integrally with the fixing part 410 and the adjustment part, and the first axis 412 of the fixing part 410 is the rotation axis of the eccentric wheel, and the rotation axis deviates from the geometric center of the eccentric wheel, so that when the eccentric wheel rotates around the rotation axis, when different positions of the eccentric wheel rotate in the second direction, the distance between the edge of the eccentric wheel in the second direction and the rotation axis is different, that is, the size of the adjustment part 420 and the first position 411 along the second direction is different. The adjustment part can also be a cam structure formed integrally with the fixing part 410 and the adjustment part, etc.

[0136] Specifically, in this embodiment, continue to refer to Figures 7 to 12 As shown, the adjustment portion 420 includes at least two adjustment arms 423, one end of the adjustment arm 423 is connected to the circumferential side wall of the fixed portion 410, all the adjustment arms 423 are arranged at intervals along the rotation direction of the fixed portion 410, and one end of any adjustment arm 423 away from the fixed portion 410 forms an adjustment position 421.

[0137] In particular, along the rotation direction of the fixing portion 410 (i.e., the circumferential direction of the fixing portion 410), the plurality of adjustment arms 423 may be arranged at equal intervals, that is, along the rotation direction of the fixing portion 410, the intervals between the plurality of adjacent adjustment arms 423 are the same. Of course, along the rotation direction of the fixing portion 410, the plurality of adjustment arms 423 may also be arranged at unequal intervals.

[0138] The fixing portion 410 may be a circular structure, with the first axis 412 located at the center of the fixing portion 410. The lengths of the plurality of (two or more) adjusting arms 423 may all be different. The plurality of adjusting arms 423 are sequentially spaced along the circumferential side wall of the fixing portion 410 and connected to the circumferential side wall of the fixing portion 410. Since the lengths of the plurality of adjusting portions 420 are different, and the distance between any point of the circumferential side wall of the fixing portion 410 and the first axis 412 (i.e., the center of the fixing portion 410) is the same, the minimum distance between the plurality of adjusting portions 420 and the first axis 412 (i.e., the radial distance between the plurality of adjusting portions 420 and the center of the fixing portion 410) is different, so that the size between the adjusting portion 420 and the first position 411 along the second direction is adjustable.

[0139] Along the rotation direction of the fixing portion 410 (ie, the circumferential direction of the fixing portion 410 ), the length sequence of the plurality of adjustment arms 423 may be increasing or decreasing in sequence, may increase first or decrease first, or may be arranged alternately in a mixed manner.

[0140] Optionally, in some embodiments, along the rotation direction of the fixing portion 410 (ie, the circumferential direction of the fixing portion 410 ), the first distances A between all the adjustment arms 423 and the first axis 412 may increase sequentially.

[0141] Among them, all the adjustment arms 423 are defined as all the adjustment arms 423 provided on a second adjustment member 400. Fig.12 As shown, when the fixing portion 410 is circular, the lengths of all the adjustment arms 423 can be set to increase sequentially along the circumference of the fixing portion 410, so that the first distance A between the first axis 412 and all the adjustment arms 423 can be increased sequentially. In other words, along the rotation direction of the fixing portion 410, the lengths of two adjacent adjustment arms 423 are different, and the length of the upstream adjustment arm 423 is less than the length of the downstream adjustment arm 423. It should be noted that the length of the adjustment arm 423 increases sequentially, which is described with the adjustment arm 423 with the smallest length as the starting point and the adjustment arm 423 with the largest length as the end point. Since the rotation direction of the fixing portion 410 is circumferential, the adjustment arm 423 with the largest length is downstream of the adjustment arm 423 with the smallest length. Along the rotation direction, between the adjustment arm 423 with the smallest length and the adjustment arm 423 with the largest length, the lengths of the multiple adjustment arms 423 increase sequentially. All the adjustment arms 423 are sequentially increased along the circumference of the fixing part 410 , so when adjusting the length (size) between the adjustment part 420 and the first position 411 along the second direction, the operator can operate more conveniently by only rotating the fixing part 410 in the corresponding direction.

[0142] It should be explained that the rotation direction of the fixing portion 410 can be the clockwise direction of the fixing portion 410 or the counterclockwise direction. The number of the adjustment arms 423 can be an even number or an odd number. Along the rotation direction of the fixing portion 410, the difference between the lengths of adjacent adjustment arms 423 can be 0.05 mm to 3 mm (specifically, it can be 0.05 mm, 0.1 mm, 0.2 mm, etc.), and the difference between adjacent adjustment arms 423 in the plurality of adjustment arms 423 can be the same. For example, the number of the adjustment arms 423 can be 6, and the difference between the lengths of adjacent adjustment arms 423 can be 0.2 mm. In this way, the adjustment arm 423 with the smallest length (the first adjustment arm 4231) is the reference adjustment arm 423, and the adjustment arm 423 with the smallest length is the reference adjustment arm 423. The length of the adjacent adjustment arm 423 (the second adjustment arm 4232) is equal to the reference adjustment arm 423 plus 0.2 mm. In order, the length of the third adjustment arm 4233 is equal to the length of the second adjustment arm 4232 plus 0.2 mm, the length of the fourth adjustment arm 4234 is equal to the length of the third adjustment arm 4233 plus 0.2 mm, the length of the fifth adjustment arm 4235 is equal to the length of the fourth adjustment arm 4234 plus 0.2 mm, and the length of the sixth adjustment arm 4236 is equal to the length of the fifth adjustment arm 4235 plus 0.2 mm.

[0143] The number of the second adjusting members 400 may be multiple, and any second adjusting member 400 may be detachably mounted on the second door body 200. The adjustable ranges of the multiple second adjusting members 400 may be set to be different, so that the second adjusting member 400 may be selected to be connected to the second door body 200 as needed, and when the second adjusting member 400 cannot meet the adjustment requirements in the second direction, the second adjusting member 400 on the second door body 200 may be replaced.

[0144] Further, the adjusting arm 423 can be arranged in an arc shape. Specifically, the adjusting arm 423 is an arc shape that protrudes outward relative to the fixing portion 410 (away from the center point of the fixing portion 410 is outward). The fixing portion 410 cooperates with a plurality of adjusting arms 423 to form the second adjusting member 400 in a shape similar to a plum blossom dart or a lotus petal. It is understandable that the adjusting arm 423 is arranged in an arc shape, so that the second adjusting member 400 is more beautiful. At the same time, the end of the adjusting arm 423 away from the fixing portion 410 is usually the abutting end 422 that abuts against the limiting portion 310. The adjusting arm 423 arranged in an arc shape makes the abutting end 422 of the adjusting arm 423 an arc transition. When the second door body 200 and the first door body 100 are connected by the first adjusting member 300 and the second adjusting member 400, when the rotating fixing portion 410 adjusts the first door body 100 and the second door body 200 along the second direction (in the height direction Y in this embodiment), the resistance of the fixing portion 410 is reduced, which facilitates the rotation operation.

[0145] The fixing portion 410 of the second adjusting member 400 of this embodiment may be provided with a positioning hole 413, and the positioning hole 413 is connected to the second door body 200 through a rotating shaft. Usually, after the size between the adjusting portion 420 and the first position 411 along the second direction is adjusted appropriately, the fixing portion 410 needs to be further fixed to prevent the fixing portion 410 from rotating. Figures 7 to 12 As shown, a fixing hole 415 is provided on the fixing portion 410, and the door body assembly further includes a fastener, which is used to pass through the fixing hole 415 to fix the second adjusting member 400 to the second door body 200, wherein there can be multiple fixing holes 415, and the multiple fixing holes 415 can be arranged at intervals along the circumference of the fixing portion 410. The fastener can be a bolt or a screw, and the fastener passes through the fixing hole 415 to lock the fixing portion 410 on the second door body 200, so that the fixing portion 410 and the second door body 200 are relatively fixed.

[0146] Implementation Method 2

[0147] The difference between the second embodiment and the first embodiment is that the second adjusting member 400 is fixed to the second door body 200 in a different manner. Specifically, the door body assembly further includes a first base 500, the first base 500 is used to connect with the second door body 200, the fixing portion 410 is used to connect to the first base 500, one of the first base 500 and the second adjusting member 400 is provided with a positioning hole 413, and the other is provided with a positioning protrusion 510, and the positioning protrusion 510 is clamped in the positioning hole 413.

[0148] like Fig.16 and Fig.17 As shown, in this embodiment, a positioning protrusion 510 is protruded from the first base 500, and a positioning hole 413 is provided on the fixing portion 410. The positioning protrusion 510 and the inner wall of the positioning hole 413 are provided with a buckle structure 416 that cooperates with each other, so that the fixing portion 410 and the first base 500 are snap-fitted. The first base 500 and the second adjusting member 400 can be repeatedly disassembled and assembled, and the first base 500 and the fixing portion 410 can be directly snapped or screwed.

[0149] In actual use, the first base 500 is connected to the second door body 200, and specifically, the first base 500 and the second door body 200 are fixedly connected by screws. During the assembly process, the fixing block can be rotated relative to the first base 500 so that the appropriate adjustment arm 423 is in the second direction, that is, the dimension between the adjustment part 420 and the first position 411 along the second direction is adjusted to the right position, and then the fixing part 410 is clamped in the positioning hole 413 through the positioning protrusion 510, so that the second adjustment member 400 is fixed to the first base 500. In some cases, after the positioning protrusion 510 is clamped in the positioning hole 413, the positioning protrusion 510 can rotate in the positioning hole 413. At this time, the fixing part 410 can be clamped in the positioning hole 413 through the positioning protrusion 510, and then the fixing part 410 is rotated by applying torque to the fixing part 410 to adjust the adjustment arm 423, thereby adjusting the dimension between the adjustment part 420 and the first position 411 along the second direction.

[0150] Furthermore, one of the inner wall of the positioning hole 413 and the circumferential side wall of the positioning protrusion 510 is provided with a convex rib 520, and the other is provided with a positioning groove 414, and the convex rib 520 is used for plugging and matching with the positioning groove 414. Fig.16 As shown, in this embodiment, the convex rib 520 is provided on the positioning convex portion 510, and the positioning groove 414 is provided on the inner wall of the positioning hole 413. The convex rib 520 and the positioning groove 414 can limit the rotation of the fixing portion 410 relative to the first base 500, and after the size between the adjusting portion 420 and the first position 411 along the second direction is adjusted appropriately, the possibility of the fixing portion 410 rotating can be reduced.

[0151] Alternatively, if Fig.16 As shown, the number of ribs 520 is the same as the number of adjustment arms 423, and multiple ribs 520 are arranged at intervals along the circumference of the positioning protrusion 510, and the positioning grooves 414 are arranged one by one corresponding to the ribs 520. The ribs 520 are elastic and can slide out of the positioning grooves 414 along the circumference of the positioning protrusion 510 after being compressed.

[0152] The ribs 520 may be made of rubber. Each rib 520 extends along the axial direction of the positioning protrusion 510 and is disposed on the circumferential side wall of the positioning protrusion 510. The ribs 520 and the positioning protrusion 510 may be an integral structure, or the ribs 520 may be separately assembled to the positioning protrusion 510. The circumference of the positioning protrusion 510, the circumference of the positioning hole 413, and the circumference of the fixing portion 410 are in the same direction. Along the circumference of the positioning protrusion 510, multiple ribs 520 can be arranged at equal intervals, and multiple adjustment arms 423 can also be arranged at equal intervals, and the central angle between adjacent ribs 520 is the same as the central angle between adjacent adjustment arms 423. In this way, the ribs 520 and the positioning grooves 414 form an installation limit structure, which can ensure that the position of the adjustment arm 423 at each angle of the second adjustment member 400 is stable relative to the first base 500. That is to say, when the positioning protrusion 510 rotates in the positioning hole 413, when it rotates to the non-gear position, the ribs 520 are limited and pressed down, and when it rotates to the gear position, the limit ribs rebound and fall into the positioning groove 414 to achieve precise positioning of the rotation angle.

[0153] The second embodiment focuses on describing the differences from the first embodiment, and for other parts not described, reference may be made to the first embodiment.

[0154] Implementation Method 3

[0155] The difference between the third embodiment and the first and second embodiments is that the adjustment arms 423 exist in pairs, and the total length of each pair of adjustment arms 423 is the same.

[0156] Specifically, if Figure 8 and Fig.11 As shown, in some embodiments, the number of adjustment arms 423 is an even number, which can be 4, 6, 8, 10, etc., and the multiple adjustment arms 423 are divided into multiple pairs, and any pair of adjustment arms 423 has two adjustment arms 423, and the two adjustment arms 423 in each pair of adjustment arms 423 are located on opposite sides of the fixed part 410.

[0157] The connection position of each pair of adjustment arms 423 and the fixing part 410 can be roughly axially symmetrical. Specifically, the axis of symmetry between the connection positions of each pair of adjustment arms 423 and the fixing part 410 can be the first axis 412, and the connection positions of each pair of adjustment arms 423 and the fixing part 410 can also be understood as being centrally symmetrically arranged with respect to the center point of the fixing part 410. The distance between the two adjustment arms 423 in each pair of adjustment arms 423, which are opposite to each other, is the second distance B, and the second distances B of the multiple pairs of adjustment arms 423 are the same.

[0158] The connection positions of each pair of adjustment arms 423 and the fixing part 410 are arranged in axisymmetry, that is, the connection line of each pair of adjustment arms 423 passes through the center point of the fixing part 410. It should be noted that in this embodiment, "substantially symmetrical" includes the meaning of symmetry or approximately symmetry, that is, symmetry is not strictly required. In other words, one adjustment arm 423 and the other adjustment arm 423 in each pair of adjustment arms 423 are on opposite sides of the fixing part 410, which can be considered symmetrical. As for whether the sizes of the connection positions of the two adjustment arms 423 of each pair of adjustment arms 423 are completely consistent, there is no strict requirement.

[0159] The second distances B of multiple pairs of adjustment arms 423 being the same can be understood as, along the radial direction of the fixing portion 410, the distance between one end of each pair of adjustment arms 423 away from the fixing portion 410 and the end of the other adjustment arm 423 away from the fixing portion 410 is the second distance B, and the second distance B is a constant, so that the radial dimension of the overall second adjustment member 400 along the fixing portion 410 is the same for each pair of adjustment arms 423.

[0160] In a specific embodiment, if Fig.11As shown, the number of the adjustment arms 423 is 6, the adjustment arm 423 with the smallest length (the first adjustment arm 4231) is the reference adjustment arm 423 (the first adjustment arm 4231), the length of the adjustment arm 423 opposite to the reference adjustment arm 423 (the adjustment arm 423 is the dimension from the end of the adjustment arm 423 away from the fixing portion 410 to the end of the adjustment arm 423 connected to the fixing portion 410) is 3 mm longer than the first adjustment arm 4231, and along the rotation direction of the fixing portion 410, the second adjustment arm 4232 is adjacent to the reference adjustment arm 423, and the second adjustment arm 4234 is adjacent to the reference adjustment arm 423. 2 is 0.2 mm longer than the first adjustment arm 4231, the adjustment arm 423 opposite to the second adjustment arm 4232 is the fourth adjustment arm 4234, and the length of the fourth adjustment arm 4234 is 2.8 mm longer than the first adjustment arm 4231; along the rotation direction of the fixing portion 410, the third adjustment arm 4233 is adjacent to the second adjustment arm 4232, and the length of the third adjustment arm 4233 is 0.4 mm longer than the first adjustment arm 4231, and the adjustment arm 423 opposite to the third adjustment arm 4233 is the sixth adjustment arm 4236, and the sixth adjustment arm 4236 is 2.6 mm longer than the first adjustment arm 4231.

[0161] like Fig.11 As shown, the second adjusting member 400 of this implementation can be used in conjunction with the first adjusting member 300 having the slide groove 320. Figure 8 As shown, the width of the slide groove 320 ( Figure 8 The dimension of the middle slide groove 320 in the vertical direction is the width of the slide groove 320 ) is a fixed value. By setting the second distance B to a fixed value, no matter which adjustment arm 423 of the second adjustment member 400 is supported by the slide groove 320 (i.e., the limit portion 310 ), the matching clearance between the second adjustment member 400 and the slide groove 320 remains unchanged. Figure 8 As shown, K is the width of the slide groove 320, Figure 8 Two identical second adjusting members 400 are used, one second adjusting member 400 is supported by a support arm of one length and the slide groove 320, and the other second adjusting member 400 is supported by a support arm of another length and the slide groove 320. The center line of the two second adjusting members 400 has been tilted, so that the second door body 200 connected thereto has changed in height at both ends relative to the slide groove 320, but the top gap a of the two second adjusting members 400 is the same because the second distance B is controlled by a constant value.

[0162] It should be noted that the third embodiment focuses on describing the differences between the first and second embodiments, and other parts not described can refer to the first and second embodiments.

[0163] Implementation Method 4

[0164] like Fig.18 As shown, the fourth embodiment is different from the first embodiment, the second embodiment and the third embodiment. The fourth embodiment achieves the size adjustment between the overall adjustment portion and the first position 411 along the second direction by replacing the adjustment portion 420 with different lengths on the fixing portion 410 .

[0165] Specifically, the second adjusting member 400 includes a fixing portion 410 and a plurality of adjusting portions 420 , at least two of the plurality of adjusting portions 420 have different lengths along the second direction, and any one of the plurality of adjusting portions 420 can be replaceably connected to the fixing portion 410 .

[0166] The fixing portion 410 can be connected with the adjusting portion 420 by snapping. Fig.18 As shown, one end of the fixing part 410 may be used to connect with the second door body 200, the other end of the fixing part 410 is provided with a clamping protrusion, and the adjusting part 420 is provided with a clamping slot, and the fixing part 410 is fixed to the adjusting part 420 by clamping the clamping protrusion with the clamping slot. A buckle structure 416 may also be provided on the clamping protrusion and the slot to enhance the connection stability of the fixing part 410 and the adjusting part 420.

[0167] It should be noted that Figure 8 The arrow in FIG. 4 indicates that the adjusting portion 420 is assembled to the fixing portion 410 in the direction indicated by the installation arrow.

[0168] In this implementation, the fixing portion 410 may be provided with a positioning hole 413 and a fixing hole 415, and both the positioning hole 413 and the fixing hole 415 may be used in conjunction with fasteners to fix the fixing portion 410 to the second door body 200. The fixing portion 410 may also be mounted on the second door body 200 in the form of a first base 500, which will not be described in detail herein.

[0169] According to some embodiments of the present application, optionally, the door body assembly of the present embodiment also includes a third adjusting member 600, and the third adjusting member 600 is arranged between the first adjusting member 300 and the first door body 100 and / or the third adjusting member 600 is used to be arranged between the second adjusting member 400 and the second door body 200. The third adjusting member 600 can be used to adjust the relative position of the second door body 200 and the first door body 100 along a third direction Z, and the third direction Z is perpendicular to the mounting surface 101.

[0170] The third direction Z is equivalent to the thickness direction of the door assembly, which is consistent with the front-to-back direction of the home appliance. The third adjusting member 600 can be arranged on the side of the second adjusting member 400 facing the second door body 200, or on the side of the first adjusting member 300 facing the first door body 100.

[0171] Specifically, in some implementations, the third adjusting member 600 includes a plurality of gaskets 610, at least two of the plurality of gaskets 610 have different thicknesses along the third direction Z, and at least one of the plurality of gaskets 610 is used to be disposed between the first adjusting member 300 and the first door body 100 or between the second adjusting member 400 and the second door body 200. By selecting gaskets 610 of different thicknesses, the relative positions of the first door body 100 and the second door body 200 in the third direction Z can be adjusted. Fig.15 As shown, in some embodiments, the gasket 610 may be provided with holes, which may be provided in a one-to-one correspondence with the fixing holes 415 on the fixing portion 410, so that the fixing portion 410 and the gasket 610 may be fixed to the second door body 200 together by fasteners.

[0172] In this embodiment, the third adjusting member 600 is provided on the side of the second adjusting member 400 facing the second door body 200 as an example for description. Fig.13 and Fig.14 As shown, the thickness of the second adjusting member 400 along the third direction Z is C, and a gasket 610 is provided on the side of the second adjusting member 400 facing the second door body 200. The size of the second adjusting member 400 and the gasket 610 is C1. The thickness of the second adjusting member 400 along the third direction Z can be adjusted by the gasket 610, so as to adjust the relative position of the second door body 200 relative to the first door body 100 in the third direction Z. It can be understood that, by combining the second adjusting member 400 with the gasket 610, a small number of second adjusting members 400 and gaskets 610 can be designed to combine a plurality of second adjusting members 400 with different thicknesses for use.

[0173] It should be noted that the gasket 610 is usually disposed corresponding to the fixing portion 410 , that is, the gasket 610 may not extend to the position corresponding to the adjustment arm 423 to avoid mutual interference between the gasket 610 and the adjustment arm 423 .

[0174] In some other implementations, the third adjusting member 600 includes a second base 620 , and the first adjusting member 300 and / or the second adjusting member 400 are disposed on the second base 620 , and their positions along the third direction Z are adjustable relative to the second base 620 .

[0175] In this embodiment, the third adjusting member 600 is provided on the side of the second adjusting member 400 facing the second door body 200 as an example for main description. Fig.19As shown, the third adjusting member 600 includes a second base 620, the fixing portion 410 of the second adjusting member 400 is mounted on the second base 620, and the position of the fixing portion 410 on the second base 620 along the third direction Z is adjustable. The fixing portion 410 may be provided with a first thread, the second base 620 may be provided with a second thread, the first thread is meshed with the second thread, and the axes of the first thread and the second thread extend along the third direction Z. By rotating the fixing portion 410 relative to the second base 620, the fixing portion 410 may move relative to the second base 620 along the third direction Z under the action of the thread meshing, thereby realizing the adjustment of the relative position of the fixing portion 410 relative to the second base 620 in the third direction Z.

[0176] Specifically, Fig.19 As shown, in this embodiment, a positioning hole 413 is provided on the fixing portion 410, and the hole wall of the positioning hole 413 is provided with an internal thread, and a threaded column 621 is provided on the second base 620, and the threaded column 621 is provided with an external thread. The threaded column 621 is screwed into the positioning hole 413, and the position of the fixing portion 410 on the threaded column 621 can be adjusted by rotating the fixing portion 410 relative to the threaded column 621 along the rotation direction D. It should be noted that, in addition to being provided with an external thread, the second base 620 can also cooperate with the fixing portion 410 to form an installation limiting structure, and the specific details can refer to the introduction of the rib 520 and the positioning groove 414 that cooperate with the first base 500 and the fixing portion 410. It should also be noted that, since the second base 620 needs to rotate relative to the fixing part 410 to adjust the relative position in the third direction Z, when used in combination with the above-mentioned embodiments one and two, in order to avoid affecting the rotation of the fixing part 410 to adjust the relative position in the second direction, the second base 620 and the fixing part 410 can be rotated relative to each other, first adjusted into place in the third direction Z, and then the second base 620 is fixed to the second door body 200, and the second base 620 is rotatable relative to the second door body 200. In this way, the rotation of the second base 620 relative to the second door body 200 can synchronously drive the fixing part 410 to rotate, thereby realizing adjustment in the second direction.

[0177] According to some embodiments of the present application, optionally, the number of the second adjustment members 400 is at least two, and at least two second adjustment members 400 are arranged at intervals along the first direction.

[0178] It should be noted that the two second adjustment members 400 spaced apart along the first direction refer to the state that the second adjustment members 400 are arranged on the second door body 200. Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, a plurality of second adjusting members 400 sequentially arranged along the first direction may be connected to the second door body 200. The second adjusting members 400 spaced apart along the first direction may be used in conjunction with the same first adjusting member 300.

[0179] According to some embodiments of the present application, optionally, along the second direction, at least two first adjustment members 300 are provided at intervals on the mounting surface 101 , and at least one of the at least two first adjustment members 300 is matched with a second adjustment member 400 .

[0180] In this embodiment, if Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, two first adjusting members 300 are provided in the height direction Y of the first door body 100 . The two first adjusting members 300 can both be matched with a second adjusting member 400 , and each first adjusting member 300 can be matched with a plurality of second adjusting members 400 along the first direction.

[0181] It can be understood that as long as there is a first adjustment member 300 that is matched with the second adjustment member 400, the relative adjustment of the first door body 100 and the second door body 200 in the height direction Y and the width direction X can be achieved. Therefore, it is not necessary for all first adjustment members 300 to be matched with the second adjustment member 400 provided in this embodiment. In some schemes, some of the first adjustment members 300 can be configured with a sliding plate 430 that only has a sliding function, and the sliding plate 430 is connected to the second door body 200 to play a role in guiding sliding. In this embodiment, the number of first adjustment members 300 includes two arranged along the height direction Y, referring to Figure 2 As shown, the second door body 200 is provided with the second adjusting member 400 only at a position corresponding to the upper first adjusting member 300 , and the second door body 200 is provided with a sliding piece 430 at a position corresponding to the lower second adjusting member 400 .

[0182] According to some embodiments of the present application, optionally, the door assembly further includes a second door 200, and the second door 200 is connected to the second adjusting member 400. The first door 100 is a door of a refrigerating appliance and the second door 200 is a cabinet door of a cupboard, or the first door 100 is a cabinet door of a cupboard and the second door 200 is a door of a refrigerating appliance, and the refrigerating appliance is used to be arranged in the cupboard.

[0183] The refrigeration appliance may be a refrigerator, and the refrigerator door body 10 may be a form in which all storage spaces are opened and closed through an integral door body, or may be a form in which a plurality of independently opened and closed door bodies are provided. For example, the refrigerator compartment has an independent door body, and the freezer compartment has an independent door body. The door body of the refrigerator compartment and the door body of the freezer compartment are separate and independent of each other, and can be controlled to be opened or closed separately. In the present embodiment, the independently opened door bodies of the refrigerator may all be refrigerator door bodies 10, that is, a cabinet panel 20 may be provided on the outside of any openable door body of the refrigerator, and the cabinet panel 20 and the corresponding door body are opened and closed synchronously. In the case where the refrigerator has a plurality of independently provided door bodies, the cabinet panel 20 also has a plurality of cabinet panels, and the cabinet panels 20 and the refrigerator door bodies 10 are provided in a one-to-one correspondence. In the case where the refrigerator has multiple independently arranged door bodies, different sliding directions can be adopted between the cabinet panels 20 corresponding to the multiple independent door bodies. For example, the first direction of one door body and the corresponding cabinet panel 20 is the width direction X of the entire refrigerator, and the door body and the cabinet panel 20 are connected by sliding cooperation along the width direction X of the refrigerator; the first direction of another door body and the corresponding cabinet panel 20 is the height direction Y of the entire refrigerator, and the door body and the cabinet panel 20 are connected by sliding cooperation along the height direction Y of the refrigerator.

[0184] The thickness of the cabinet door along the third direction Z is in the range of 6 mm to 30 mm. Specifically, along the third direction Z, the thickness of the cabinet board 20 is in the range of 6 mm to 12 mm, or, along the third direction Z, the thickness of the cabinet board 20 is in the range of 15 mm to 25 mm.

[0185] Specifically, the thickness of the cabinet board 20 may be 6 mm, 9 mm, or 12 mm. The thickness of the cabinet board 20 may also be 15 mm, 18 mm, or 25 mm.

[0186] In some embodiments, the thickness of the cabinet board 20 along the third direction Z can be 9 mm or about 9 mm, or 18 mm or about 18 mm, or 20 mm or about 20 mm. Wherein about 9 mm and about 18 mm can be understood as the size within the processing error range allowed by the process when processing the cabinet board 20 of the standard size with 9 mm or 18 mm as the standard size.

[0187] Optionally, along the third direction Z, a width E of the gap 30 between the first door body 100 and the second door body 200 is 0.1 mm to 4.5 mm.

[0188] It is understandable that, since the first adjusting member 300, the second adjusting member 400 and the third adjusting member 600 are provided between the cabinet plate 20 and the refrigerator door body 10 (that is, between the first door body 100 and the second door body 200), it is usually difficult to achieve no gap 30 between the cabinet plate 20 and the refrigerator door body 10, but if the gap 30 is too large, the thickness space occupied will inevitably increase, affecting the user experience. In this embodiment, through the corresponding structural arrangement of the first adjusting member 300, the second adjusting member 400 and the third adjusting member 600, the width E of the gap 30 between the cabinet door and the refrigerator door body 10 can be 0.1 mm to 4.5 mm, specifically 0.1 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, 4.5 mm, so that the thickness space occupied by the door assembly is small, which improves the user experience and space utilization.

[0189] Specifically, refer to Figure 3 and Figure 4 As shown, the first adjusting member 300 and the second adjusting member 400 are assembled to obtain an integral structure, and the thickness along the third direction Z can be set to be less than or equal to 8 mm, which can not only reduce the thickness space occupied by the door body assembly, but also save consumables. Figure 3 As shown, when the thickness T of the first adjusting member 300 and the second adjusting member 400 along the third direction Z after being assembled is greater than the gap set between the first door body 100 and the second door body 200, a mounting groove 350 can be opened on the surface of the first door body 100 and the second door body 200, and the first adjusting member 300 and the second adjusting member 400 can be installed through the mounting groove 350. In this way, part of the first adjusting member 300 or part of the second adjusting member 400 is embedded in the mounting groove 350, which can reduce the gap between the first door body 100 and the second door body 200.

[0190] In this embodiment, after the first door body 100 and the second door body 200 are adjusted into place in any direction by the first adjusting member 300, the second adjusting member 400 and the third adjusting member 600, the first door body 100 and the second door body 200 can be fixedly connected by the fixing member 700.

[0191] Specifically, Figure 20 to Figure 22As shown, the door body assembly also includes a fixing member 700, and the fixing member 700 may include a first connecting plate 710 and a second connecting plate 720. The first connecting plate 710 and the second connecting plate 720 may be an integral structure or a fixedly connected structure. The first connecting plate 710 is provided with a first mounting hole 730, and the first mounting hole 730 is used to cooperate with a columnar fastener to fix the first connecting plate 710 to the first door body 100. The second connecting plate 720 is provided with a second mounting hole 740, and the second mounting hole 740 is used to cooperate with a columnar fastener to fix the second connecting plate 720 to the second door body 200. One of the first mounting hole 730 and the second mounting hole 740 is a strip hole, and the position of the columnar fastener cooperating with the strip hole is adjustable along the length direction of the strip hole.

[0192] Among them, the column fastener can be a screw, and the cooperation between the column fastener and the first mounting hole 730 can be that one end of the column fastener passes through the first mounting hole 730 to connect with the first door body 100, and the other end of the column fastener presses on the first connecting plate 710; the cooperation between the column fastener and the second mounting hole 740 can be that one end of the column fastener passes through the second mounting hole 740 to connect with the second door body 200, and the other end of the column fastener presses on the second connecting plate 720. The length direction of the strip hole refers to the direction in which the length of the strip hole is the largest in the direction perpendicular to its own axial direction. The strip hole makes the setting position of the column fastener more flexible, which facilitates the assembly and fixation of the first door body 100 and the second door body 200.

[0193] The first connecting plate 710 and the second connecting plate 720 may be connected in the same plane or may be connected in an intersecting manner, as long as the first connecting plate 710 and the second connecting plate 720 correspond to the first door body 100 and the second door body 200 respectively.

[0194] In one embodiment, the plate surface of the first connecting plate 710 and the plate surface of the second connecting plate 720 are perpendicular to each other, the plate surface of the first connecting plate 710 is parallel to the third direction Z, the first mounting hole 730 is a strip hole, and the length direction of the strip hole is parallel to the third direction Z, and the third direction Z is perpendicular to the mounting surface 101.

[0195] Specifically, the second connecting plate 720 and the first connecting plate 710 can be connected to form an L-shaped plate, the first connecting plate 710 has a first end and a second end that are relatively arranged, the first end is fixedly connected to the second connecting plate 720, the first mounting hole 730 on the first connecting plate 710 is a strip hole, the strip hole extends from the first end to the second end, and a columnar fastener is passed through the strip hole to fix the first connecting plate 710 to the first door body 100, and the columnar fastener can move in the strip hole along the length direction of the strip hole.

[0196] The following takes the example of the first connecting plate 710 being connected to the refrigerator door 10 and the second connecting plate 720 being connected to the cabinet board 20 as an example to specifically describe the fixing member 700. Figure 20 to Figure 22 As shown, in the width direction X, the cabinet plate 20 can be slightly wider than the width of the refrigerator door body 10, and the fixing member 700 is arranged at one end of the width direction X of the refrigerator door body 10 and is located on the inner side where the cabinet plate 20 is wider than the refrigerator door body 10, so that the first connecting plate 710 can be attached and connected to the end of the refrigerator door body 10 in the width direction X, and the second connecting plate 720 is attached and connected to the inner side of the cabinet plate 20. In some implementations, such as Fig. 20 and Fig.21 As shown, the end of the refrigerator door body 10 in the width direction X may be provided with a mounting groove, and the first connecting plate 710 may be arranged in the mounting groove. Among them, the second connecting plate 720 may be provided with one or two second mounting holes 740, and a cylindrical fastener (such as a screw, etc.) passes through the assembly hole to connect the second connecting plate 720 to the refrigerator door body 10; the first connecting plate 710 is provided with a strip hole, and the strip hole extends along the third direction Z. The cylindrical fastener may be a screw, and the cylindrical fastener passes through the strip hole to connect the first connecting plate 710 to the refrigerator door body 10. Since the strip hole has a certain adjustment space in the third direction Z, the matching degree of the first door body 100 and the second door body 200 in the third direction Z is relatively low, so that the assembly flexibility of the fixing member 700 is improved.

[0197] Some embodiments of the present application also provide a household appliance, including an appliance body, and also including a door body assembly proposed in the present application or any embodiment of the present application, the appliance body is provided with a accommodating cavity with an opening, the door body assembly is connected to the appliance body, and is opened and closed at the opening.

[0198] The household appliance may be a refrigeration appliance, specifically a refrigerator, and the device body is the body of the refrigeration appliance, specifically the body of the refrigerator. In other words, the refrigerator body and the door assembly constitute a refrigerator. The household appliance may also be a cabinet, and the device body is the cabinet body, that is, the cabinet body and the door assembly constitute a complete cabinet. The household appliance may also be a cabinet and an embedded refrigeration appliance assembly, and the device body may be the cabinet body and the body of the refrigeration appliance, that is, the door assembly includes a first door body 100 and a second door body 200 connected to each other, the device body includes a cabinet body and a refrigeration appliance body, the opening of the cabinet body and the opening of the refrigeration appliance body are oriented in the same direction, one of the first door body 100 and the second door body 200 is disposed at the opening of the body of the refrigeration appliance for sealing the body of the refrigeration appliance, and the other corresponds to the opening of the cabinet body.
