[0089] As shown in Figures 1 to 22, according to an embodiment of the present application, a door assembly is provided, comprising a first door body 100, a first adjusting member 300, and a second adjusting member 400. A side panel of the first door body 100 forms a mounting surface 101. The first adjusting member 300 is disposed on the mounting surface 101. The first adjusting member 300 is provided with a stopper 310, which extends along a first direction. The second adjusting member 400 includes a fixed portion 410 and an adjusting portion 420 connected to each other. The fixed portion 410 has a first position 411 for connecting and positioning with the second door body 200. The distance between the adjusting portion 420 and the first position 411 is adjustable along a second direction. The adjusting portion 420 is configured to connect to the first adjusting member 300. The adjusting portion 420 and the first adjusting member 300 are capable of relative sliding along the first direction, and the adjusting portion 420 can cooperate with the stopper 310 to limit the position in the second direction. The first direction is perpendicular to the second direction, and the first and second directions are respectively parallel to the mounting surface 101.

[0090] It should be noted that in 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 in Figure 1, the first adjusting member 300 and the second adjusting member 400 are displayed in perspective, so that from 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. 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 mounting surface 101 of the first door body 100.

[0091] 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 door of a cabinet, or the first door body 100 can be the 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 refrigerator or freezer, specifically a refrigerator or the like. 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 explained by taking the example of the first door body 100 being assembled with the corresponding device body and the second door body 200 being fixedly assembled to the first door body 100. 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 cooperate with each other usually 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 device body of the household appliance can be assembled into an integral piece of furniture. For example, in cabinets and built-in refrigerators, the first door body 100 is usually the refrigerator door body 10, and the refrigerator is transported and sold as a conventional complete refrigerator.

[0092] It should also be noted that the second door body 200 can be fixed to the first door body 100, and the second door body 200 is located at the opening of the accommodating cavity of the corresponding device body. 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, and 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, and 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 not connected to the cabinet; the cabinet door can also be fixed to the refrigerator door body 10 and establish an adaptive flexible connection with the cabinet so that the cabinet door and the refrigerator door body 10 are opened or closed synchronously.

[0093] 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 stored or transported together with the first door body 100. When the first door body 100 is transported to the user's side, they are assembled onto the corresponding first door body 100 and second door body 200. In other words, during the transportation of the door assembly or the preparation of the door assembly, the first adjusting member 300 and the second adjusting member 400 can be placed as parts or accessories. When the door assembly is transported to the user's desired installation location, for example, when a 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. 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.

[0094] 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. In this way, 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 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 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 removed 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 adjustment member 300 and the second adjustment member 400 can be transported in the form of parts, or the first adjustment member 300 can be pre-installed on the first door body 100, and the second adjustment 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 adjustment member 300 and the second adjustment member 400 can be directly adjusted as needed.

[0095] 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, there may be problems of being more time-consuming and labor-intensive. This embodiment provides protection for whether the first adjusting member 300 is installed to the first door body 100, whether the second adjusting member 400 is installed to the second door body 200, and 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 multiple 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 this 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 this embodiment, they are all within the protection scope of this embodiment.

[0096] 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 practical 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. In other words, this embodiment does not impose strict requirements on perpendicularity and parallelism, and close to parallel or close to perpendicular is sufficient. For example, if the angle between the first direction and the second direction is between 85-95 degrees, the first direction and the second direction can be considered perpendicular to each other.

[0097] Specifically, the first direction may be the width direction X of the first door body 100, and correspondingly, the second direction may be 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 may be the width direction X of the first door body 100. The width direction X of the first door body 100 is perpendicular to the height direction Y of the first door body 100, and both the width direction X of the first door body 100 and the height direction Y of the first door body 100 are parallel to the mounting surface 101. It is understood that the description of the width direction X of the first door body 100 and the height direction Y of the first door body 100 are 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 a corresponding device body. For example, when 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).

[0098] The mounting surface 101 is generally 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, if the first door body 100 is the door body of a refrigeration appliance and the second door body 200 is a cabinet door, the refrigeration appliance door body is generally 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, if the second door body 200 is the door body of a refrigeration appliance and the first door body 100 is a cabinet door, the refrigeration appliance door body is generally 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.

[0099] The second adjusting member 400 is connected to the first adjusting member 300 via 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 a degree of freedom in the first direction, allowing the adjusting portion 420 and the first adjusting member 300 to slide relative to each other in the first direction, thereby adjusting the relative position of the second adjusting member 400 and the first adjusting member 300 along the first direction. The second adjusting member 400 also cooperates with the limiting portion 310 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 limited, 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 in the second direction with the first adjusting member 300.

[0100] The first adjustment member 300 may be a slide rail disposed on the mounting surface 101, and the second adjustment 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, with the length of the bar block arranged along the width direction X of the first door body 100. The upper surface of the slide rail may serve as a stopper 310, and the slider may slidably abut against the upper surface of the bar block. If the slide rail is a bar-shaped block structure, the slider may be provided with a sliding groove or a slider hole, and the slide rail is mounted within the sliding groove or sliding hole, so that the slider is mounted on the slide rail, abuts against the slide rail, and can slide along the width direction X of the first door body 100. The slide rail may also be provided with a sliding groove 320, the sidewalls of which may serve as the stopper 310, and the slider may slidably 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.

[0101] In some implementations, the fixing portion 410 of the second adjusting member 400 can first be assembled to the second door body 200 through the first position 411, and then the second adjusting member 400 can be 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 connection with the second door body 200. Since the second adjusting member 400 needs to be connected to the second door body 200, the second adjusting member 400 must have a position for connection with the second door body 200, and the second door body 200 also has a position for connection 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 cooperation of 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 connection 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.

[0102] Specifically, since the adjusting portion 420 of the second adjusting member 400 can slide with the second adjusting member 400 in the width direction X, the relative position of the first door body 100 and the second door body 200 in the first direction can be adjusted 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 adjusting the relative position of the first position 411 and the first adjusting member in the second direction.

[0103] The dimension along the second direction between the adjusting portion 420 and the first position 411 can be understood as the distance along the second direction between the position where the adjusting portion 420 is used to connect with the first adjusting member 300 and the first position 411. In some embodiments, as shown in Figures 2 to 4 and Figures 7 to 12, the end of the adjusting portion 420 away from the fixing portion 410 is used to abut against the limiting portion 310. For convenience of description, the end of the adjusting portion 420 used to abut against the limiting portion 310 is defined as the abutting end 422. The abutting end 422 is the position where the adjusting portion 300 (i.e., the limiting portion 310) is abutted and connected. Accordingly, the dimension along the second direction between the first position 411 and the adjusting portion 420 can be understood as the distance along the second direction between the abutting end 422 and the first position 411.

[0104] It should be noted that the dimension between the adjustment portion 420 and the first position 411 along the second direction is based on the second adjustment member 400 being installed on the second door body 200 or after the second adjustment member 400 is assembled with the first adjustment member 300. In the case where the second adjustment member 400 has not yet been assembled to the second door body 200 or the first adjustment member 300, the adjustment portion 420 only needs to be adjustable in one direction relative to the first position 411. Based on reasonable assembly, the dimension between the adjustment portion 420 and the first position 411 along the second direction can be adjusted so that the direction in which the dimension of the adjustment portion 420 is adjustable corresponds to the second direction.

[0105] During the actual assembly of the door assembly, the first door body 100 and the second door body 200 can be assembled, and then the relative positions of the first door body 100 and the second door body 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. During the actual assembly of the door assembly, 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 body 100 and the second door body 200 first meet the adjustment positioning requirements in the second direction, and then the second adjusting member 400 is assembled with the first adjusting member 300, and the second adjusting member 400 and the first adjusting member 300 slide relative to each other in 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 positioning requirements of the first door body 100 and the second door body 200 in the first direction. In this embodiment, unless otherwise specified, it can be understood that the relative adjustment of the first door body 100 and the second door body 200 is achieved in the latter manner.

[0106] The door assembly according to the present application can be applied to household appliances. Specifically, the first door 100 can be the door of a refrigeration appliance (such as a refrigerator) and the second door 200 can be the cabinet door, or the first door 100 can be the cabinet door and the second door 200 can be the door of a refrigeration appliance. By using the door assembly of the present application, the difficulty of assembling the refrigeration appliance and the cabinet door can be reduced and the assembly efficiency can be improved.

[0107] 1 to 9 , in some implementations (subsequent descriptions of this embodiment will primarily use this implementation as an example), 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 both the width direction X and the height direction Y through the first adjustment member 300 and the second adjustment member 400 , resulting in a simple structure and easy operation. Specifically, by arranging the first adjusting member 300 on the mounting 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, thereby realizing the adjustment of 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, since the second adjusting member 400 can slide with the limiting portion 310 of the first adjusting member 300 during the assembly process of the second door body 200 and the first door body 100, and the limiting portion 310 of the first adjusting member 300 abuts against the second adjusting member 400, 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 saves effort, reduces the difficulty of operation, and improves assembly efficiency.

[0108] According to some embodiments of the present application, optionally, the adjustment portion 420 is detachably connected to the first adjustment member 300 .

[0109] 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. In this way, when the second door body 200 is temporarily assembled to the first door body 100 only by 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 the second direction (height direction Y in this embodiment), the second door body 200 can also be removed 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 dimension between the adjusting portion 420 and the first position 411 along the second direction can be adjusted. The dimension 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, which is more convenient to operate.

[0110] 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. In this embodiment, as shown in Figures 7 to 9, the second adjusting member 400 can slide from one end of the limiting portion 310 along the width direction X to connect with the first adjusting member 300 and abut against the limiting portion 310, or slide to detach from the first adjusting member 300.

[0111] 7 to 9 , one end of the limiting portion 310 in the width direction X generally refers to the left end or the right end of the limiting portion 310 , that is, one of the two ends that are separated from each other in the width direction X. The second adjusting member 400 can slide from one 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 .

[0112] Specifically, in one implementation, as shown in Figures 7 and 8, 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 stop limiters 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 either end of the limiting portion 310. More specifically, referring to Figures 7 and 8, 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 serve 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, the two 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.

[0113] It should be noted that, in the implementation 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.

[0114] In another embodiment, as shown in FIG9 , the stopper 310 is located within the mounting surface 101 in the width direction X. A clearance notch 335 may be provided at one or both ends of the stopper 310 in the width direction X, allowing the second adjusting member 400 to slide through the clearance notch 335 to connect with the first adjusting member 300 or to detach from the first adjusting member 300 upon sliding to the clearance notch 335. In this embodiment, the first adjusting member 300 and the stopper 310 may be provided in 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 may correspond to a clearance notch 335. In this manner, the second adjusting members 400 do not need to slide from one end of the mounting surface 101 in the width direction X to the other end. Instead, each second adjusting member 400 may slide onto the first adjusting member 300 starting from its corresponding clearance notch 335. This shortens the sliding travel of the second adjusting member 400 in the width direction X and improves assembly efficiency.

[0115] In this embodiment, during the assembly of the second door body 200 onto 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 stopper 310, which is convenient and quick to operate. After the initial assembly of the first door body 100 and the second door body 200, 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 until it is 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 carried out when the first door body 100 and the second door body 200 are separated, so that the first door body 100 and the second door body 200 can be separated to adjust the height and then assembled, which is easy to operate and saves time and effort.

[0116] According to some embodiments of the present application, as shown in Figures 1 and 3 to 9, 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 can be slidably disposed in the slide groove 320.

[0117] The slide groove 320 may be formed by a local depression of 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 being extended along the width direction X and having the slide groove 320 on the track block 340. The track block 340 may be an integral structure with the first door body 100, or may be connected to the mounting surface 101 of the first door body 100 by means of connectors such as screws, welding, etc. As shown in FIG4 , the track block 340 may be mounted on the mounting surface 101 of the first door body 100 in a protruding manner, that is, the track block 340 may be provided on the surface of the mounting surface 101 and fixed to the mounting surface 101. As shown in Figure 3, 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, and the mounting groove 350 is recessed relative to the mounting surface 101. The track block 340 has a sliding groove 320, and the track block 340 is partially or completely embedded in the mounting groove 350.

[0118] The mounting groove 350 is equivalent to a groove structure formed by a local depression of the mounting surface 101, with the opening facing the mounting surface 101. On the first door body 100, the mounting groove 350 is recessed toward the side away from the mounting surface 101. The mounting groove 350 can be a groove formed by removing some material from the first door body 100.

[0119] As shown in Figures 3, 4 and 6, the slide groove 320 can be a groove with a U-shaped cross-section. Specifically, the side walls 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 arranged relative to each other, wherein the first sub-wall 331 can be located above the second sub-wall 332, and the second adjustment member 400 can be slidably arranged between the first sub-wall 331 and the second sub-wall 332.

[0120] The first sub-wall 331 or the second sub-wall 332 can serve as the limiting portion 310. Specifically, the side of the second sub-wall 332 facing the inside of the chute 320, that is, the side facing the first sub-wall 331, can serve as the limiting portion 310. The side of the first sub-wall 331 facing the inside of the chute 320, that is, the side facing the second sub-wall 332, can serve as the limiting portion 310 for cooperating with the second adjusting member 400. In the subsequent description of this embodiment, when the first sub-wall 331 is used as the limiting portion 310, it can be understood that the side of the first sub-wall 331 facing the inside of the chute 320, that is, the lower surface of the first sub-wall 331, serves as the limiting portion 310. When the second sub-wall 332 is used as the limiting portion 310, it can be understood that the side of the second sub-wall 332 facing the inside of the chute 320, that is, the upper surface of the second sub-wall 332, serves as the limiting portion 310.

[0121] 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. Specifically, as shown in FIG4 , 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. At this time, the first door body 100 is equivalent to a fixed setting, 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 adjustment of the second door body 200 relative to the first door body 100 can only be achieved by relying on the movement of the second door body 200. In this implementation, after the second adjustment 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 abutted against the second sub-wall 332 (that is, 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 abutment 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, and 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.As shown in FIG3 , in other implementations, the second door body 200 is a door body that has been assembled. For example, the second door body 200 is the refrigerator door body 10 that has been assembled. In this case, the second door body 200 is equivalent to a fixed setting, and the first door body 100 needs to be assembled to the second door body 200. In 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. During the assembly of 00 and 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 the 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.

[0122] 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.

[0123] The bottom wall 334 of the chute 320 is connected to one end of the side wall of the chute 320, and the bottom wall 334 is opposite the opening of the chute 320. As shown in Figures 3 to 6, a stopper 333 is provided at one end of the first sub-wall 331 and one end of the second sub-wall 332 away from the bottom wall 334. 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. A limited gap 336 is formed between each stopper 333 and the bottom wall 334. When the second adjusting member 400 is assembled into the chute 320, both ends of the second adjusting member 400 along the height direction Y can be respectively constrained within the corresponding limited gap 336.

[0124] 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 escaping from the slide groove 320 during the sliding process can be reduced.

[0125] 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. In this way, 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, as shown in FIG9 , an avoidance notch 335 is provided on the side wall. The avoidance notch 335 is provided at one or both ends of the stopper 333 along the width direction X. The avoidance notch 335 is used to allow the second adjusting member 420 to be inserted into the limiting gap 336. 9 , the first sub-wall 331 and the second sub-wall 332 may both be provided with an avoidance notch 335, that is, the first sub-wall 331 and the second sub-wall 332 both have a position where the stop portion 333 is not provided, and the avoidance notch 335 is formed at this position, and the avoidance notch 335 of the first sub-wall 331 and the avoidance notch 335 of the second sub-wall 332 may be aligned to facilitate the insertion of the second adjustment member 400 from the avoidance notch 335 into the position of the slide groove 320 having the stop portion 333.

[0126] 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 .

[0127] In some embodiments, there are multiple second adjustment members 400, and any second adjustment member 400 can be detachably connected to the second door body 200. 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 part 420 and the corresponding first position 411 along the second direction.

[0128] The number of the second adjusting members 400 may be two or more, and some of the plurality of second adjusting members 400 may be spare parts. That is, based on actual assembly requirements, a 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, while the adjustable ranges of some of the second adjusting members 400 may be different.

[0129] 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.

[0130] 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 different 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, and 0.6 mm, while 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, and 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, while 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.

[0131] Optionally, in some embodiments, after the size between the adjustment portion 420 and the first position 411 along the second direction is adjusted appropriately, the fixing portion 410 can be further fixed. For example, as shown in Figures 7 to 12 and 18, a fixing hole 415 can be 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 adjustment 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, 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 is passed through the fixing hole 415 to lock the fixing portion 410 on the second door body 200, so that the fixing portion 410 is relatively fixed to the second door body 200. For another example, as shown in Figures 16 and 17, a snap-fit ​​structure 416 is provided on the fixing part 410, and the snap-fit ​​structure 416 is used to enable the fixing part 410 to be snapped onto 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 snapped onto the snap-fit ​​structure 416 on the fixing part 410, so that the second adjustment member is snapped onto the second door body 200.

[0132] 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 .

[0133] 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.

[0134] Implementation Method 1

[0135] As shown in Figures 7 to 12, 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 other methods, 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 is rotatable about the first axis 412. The adjusting portion 420 is provided on a circumferential sidewall of the fixed portion 410. Along the rotation direction of the fixed portion 410, the adjusting portion 420 has at least two adjustment positions 421. Along a direction perpendicular to the first axis 412, the shortest distance between the adjustment position 421 and the first axis 412 is a first distance A. The first distances A between the at least two adjustment positions 421 and the first axis 412 are different. Under the action of the fixed portion 410 rotating about the first axis 412, any adjustment position 421 can be adjusted to be set along the second direction.

[0136] The adjustment position 421 can be understood with reference to the abutting end 422. Specifically, the adjustment position 421 is the position for abutting the limiting portion 310. The adjustment position 421 can be a point or a surface. Generally, the adjustment portion 420 can be positioned away from a point or surface on the end surface of the fixing portion 410 to form an abutting position. 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, it is 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.

[0137] 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.

[0138] In some possible solutions, the adjustment portion may be an eccentric wheel integrally formed with the fixing portion 410 and the adjustment portion. The first axis 412 of the fixing portion 410 is the rotational axis of the eccentric wheel, and the rotational axis is offset from the geometric center of the eccentric wheel. In this way, when the eccentric wheel rotates about the rotational axis, the distance between the edge of the eccentric wheel in the second direction and the rotational axis varies when the eccentric wheel rotates in the second direction at different positions. That is, the size of the adjustment portion 420 along the second direction is different from the first position 411. The adjustment portion may also be a cam structure integrally formed with the fixing portion 410 and the adjustment portion, etc.

[0139] Specifically, in this embodiment, continuing to refer to Figures 7 to 12, the adjustment part 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 part 410, all the adjustment arms 423 are arranged at intervals along the rotation direction of the fixed part 410, and any one of the adjustment arms 423 away from one end of the fixed part 410 forms an adjustment position 421.

[0140] The plurality of adjustment arms 423 may be arranged at equal intervals along the rotation direction of the fixing portion 410 (i.e., the circumference of the fixing portion 410). That is, the intervals between adjacent adjustment arms 423 are the same along the rotation direction of the fixing portion 410. Of course, the plurality of adjustment arms 423 may also be arranged at unequal intervals along the rotation direction of the fixing portion 410.

[0141] The fixing portion 410 can be a circular structure, and the first axis 412 is located at the center of the fixing portion 410. The lengths of multiple (two or more) adjustment arms 423 can all be different. The multiple adjustment arms 423 are arranged in sequence 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 multiple adjustment portions 420 are different, and the distance between any point on 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 multiple adjustment portions 420 and the first axis 412 (i.e., the radial distance between the multiple adjustment portions 420 and the center of the fixing portion 410) is different, so that the size between the adjustment portion 420 and the first position 411 along the second direction is adjustable.

[0142] Along the rotation direction of the fixing portion 410 (ie, the circumferential direction of the fixing portion 410 ), the lengths of the plurality of adjustment arms 423 may increase or decrease in sequence, may increase or decrease first, or may be arranged alternately in a mixed manner.

[0143] 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.

[0144] Here, "all adjustment arms 423" refers to all adjustment arms 423 provided on a second adjustment member 400. As shown in FIG12 , if the fixed portion 410 is circular, the lengths of all adjustment arms 423 can be configured to increase sequentially along the circumference of the fixed portion 410, such that the first distance A between the first axis 412 and all adjustment arms 423 increases sequentially. In other words, along the rotational direction of the fixed portion 410, the lengths of two adjacent adjustment arms 423 differ, 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 sequential increase in the length of the adjustment arms 423 is described starting from the smallest adjustment arm 423 and ending at the largest adjustment arm 423. Since the rotational direction of the fixed portion 410 is circumferential, the smallest adjustment arm 423 is downstream of the largest adjustment arm 423. Along the rotational direction, the lengths of the multiple adjustment arms 423 increase sequentially from the smallest adjustment arm 423 to the largest adjustment arm 423. By sequentially increasing all the adjustment arms 423 along the circumference of the fixing portion 410 , the operator can adjust the length (size) between the adjustment portion 420 and the first position 411 along the second direction more conveniently by simply rotating the fixing portion 410 in the corresponding direction.

[0145] 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 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.

[0146] There may be multiple second adjusting members 400, and any one of the second adjusting members 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 different values, 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.

[0147] Exemplarily, the adjustment arm 423 can be arranged in an arc shape. Specifically, the adjustment arm 423 is an arc shape that protrudes outward from the fixed portion 410 (away from the center point of the fixed portion 410). The fixed portion 410 and the plurality of adjustment arms 423 cooperate to form the second adjustment member 400 in a shape similar to a plum blossom dart or a lotus petal. It is understood that the arc shape of the adjustment arm 423 makes the second adjustment member 400 more aesthetically pleasing. At the same time, the end of the adjustment arm 423 away from the fixed portion 410 is generally the abutment end 422 that abuts the limit portion 310. The arc shape of the adjustment arm 423 makes the abutment end 422 of the adjustment arm 423 form an arc transition. When the second door body 200 and the first door body 100 are connected by the first adjustment member 300 and the second adjustment member 400, when the fixed portion 410 is rotated to adjust the first door body 100 and the second door body 200 along the second direction (in this embodiment, the height direction Y), the resistance of the fixing portion 410 is reduced, facilitating the rotation operation.

[0148] The fixing portion 410 of the second adjusting member 400 of this embodiment can be provided with a positioning hole 413, which is connected to the second door body 200 via 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. In this embodiment, as shown in Figures 7 to 12, 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 the fixing hole 415 can be multiple, 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 is relatively fixed to the second door body 200.

[0149] Implementation Method 2

[0150] The difference between the second embodiment and the first embodiment lies in the different ways in which the second adjusting member 400 is fixed to the second door body 200. Specifically, the door body assembly further includes a first base 500, which is used to connect to the second door body 200, and a fixing portion 410 which 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, which is engaged with the positioning hole 413.

[0151] As shown in Figures 16 and 17, 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 inner walls of the positioning protrusion 510 and the positioning hole 413 are provided with mutually cooperating snap structures 416, which enable the fixing portion 410 to engage with the first base 500. The first base 500 and the second adjusting member 400 can be repeatedly assembled and disassembled, and the first base 500 and the fixing portion 410 can be engaged by either a straight or a twisted engagement.

[0152] 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 portion 420 and the first position 411 along the second direction is first adjusted to the desired position. Then, the fixing portion 410 is engaged with the positioning hole 413 via the positioning protrusion 510 to fix the second adjustment member 400 to the first base 500. In some cases, after the positioning protrusion 510 is engaged with the positioning hole 413, the positioning protrusion 510 can be rotated within the positioning hole 413. In this case, the fixing portion 410 can be engaged with the positioning hole 413 via the positioning protrusion 510. Then, torque can be applied to the fixing portion 410 to rotate the fixing portion 410, thereby adjusting the adjustment arm 423 and further adjusting the dimension between the adjustment portion 420 and the first position 411 along the second direction.

[0153] Optionally, one of the inner wall of the positioning hole 413 and the circumferential sidewall of the positioning protrusion 510 is provided with a rib 520, and the other is provided with a positioning groove 414. The rib 520 is configured to engage with the positioning groove 414. Continuing with FIG16 , in this embodiment, the rib 520 is provided on the positioning protrusion 510, and the positioning groove 414 is provided on the inner wall of the positioning hole 413. The rib 520 and the positioning groove 414 can limit the rotation of the fixing portion 410 relative to the first base 500. This can reduce the possibility of rotation of the fixing portion 410 after the dimension between the adjustment portion 420 and the first position 411 along the second direction is appropriately adjusted.

[0154] Optionally, as shown in Figure 16, 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-to-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.

[0155] The ribs 520 can be made of rubber. Each rib 520 extends axially along the positioning protrusion 510 and is disposed on the circumferential sidewall of the positioning protrusion 510. The ribs 520 and the positioning protrusion 510 can be integrally formed, or they can be separately assembled onto the positioning protrusion 510. The circumferential directions of the positioning protrusion 510, the positioning hole 413, and the fixing portion 410 are all 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.

[0156] This embodiment 2 focuses on describing the differences from the embodiment 1. For other parts not described, reference can be made to the embodiment 1.

[0157] Implementation Method 3

[0158] 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.

[0159] Specifically, as shown in Figures 8 and 11, 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. 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.

[0160] The connection locations of each pair of adjustment arms 423 and the fixing portion 410 can be arranged approximately axially symmetrically. Specifically, the axis of symmetry between the connection locations of each pair of adjustment arms 423 and the fixing portion 410 can be the first axis 412. The connection locations of each pair of adjustment arms 423 and the fixing portion 410 can also be understood as being arranged centrally symmetrically about the center point of the fixing portion 410. The distance between the two adjustment arms 423 in each pair of adjustment arms 423 at their ends facing away from each other is a second distance B, and the second distance B is the same for multiple pairs of adjustment arms 423.

[0161] The connection locations of each pair of adjustment arms 423 and the fixing portion 410 are arranged axially symmetrically, that is, the line connecting each pair of adjustment arms 423 passes through the center point of the fixing portion 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, if one adjustment arm 423 and the other adjustment arm 423 in each pair of adjustment arms 423 are on opposite sides of the fixing portion 410, they can be considered symmetrical. As for whether the connection locations of the two adjustment arms 423 in each pair of adjustment arms 423 are completely consistent in size, this is not a strict requirement.

[0162] The second distance B of multiple pairs of adjustment arms 423 being the same can be understood as follows: 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 other end of the 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.

[0163] In a specific embodiment, as shown in FIG11 , 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), and the length of the adjustment arm 423 opposite to the reference adjustment arm 423 (the adjustment arm 423 is the fourth adjustment arm 4234) (the length of 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. 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. The length of the adjusting arm 4232 is 0.2 mm longer than that of the first adjusting arm 4231. The adjusting arm 4233 opposite to the second adjusting arm 4232 is the fourth adjusting arm 4234. The length of the fourth adjusting arm 4234 is 2.8 mm longer than that of the first adjusting arm 4231. Along the rotation direction of the fixing part 410, the third adjusting arm 4233 is adjacent to the second adjusting arm 4232. The length of the third adjusting arm 4233 is 0.4 mm longer than that of the first adjusting arm 4231. The adjusting arm 423 opposite to the third adjusting arm 4233 is the sixth adjusting arm 4236. The sixth adjusting arm 4236 is 2.6 mm longer than the first adjusting arm 4231.

[0164] As shown in Figure 11, the second adjusting member 400 of this implementation can be used in conjunction with the first adjusting member 300 having a slide groove 320. As shown in Figure 8, the width of the slide groove 320 (the dimension of the slide groove 320 in the up and down directions in Figure 8 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 adjusting arm 423 of the second adjusting member 400 is supported by the slide groove 320 (i.e., the limiting portion 310), the fitting clearance between the second adjusting member 400 and the slide groove 320 remains unchanged. As shown in Figure 8, K is the width of the slide groove 320. Two identical second adjusting members 400 are used in Figure 8. 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 connecting 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. However, the gap a at the top of the two second adjusting members 400 is the same because the second distance B is controlled by a constant value.

[0165] It should be noted that this embodiment 3 focuses on describing the differences between the embodiment 1 and the embodiment 2, and other parts not described can refer to the embodiment 1 and the embodiment 2.

[0166] Implementation Method 4

[0167] 18 , this fourth embodiment is different from the first, second, and third embodiments. In this fourth embodiment, the size between the integral adjustment portion and the first position 411 is adjusted along the second direction by replacing the adjustment portion 420 with different lengths on the fixing portion 410 .

[0168] Specifically, the second adjusting member 400 includes a fixing portion 410 and multiple adjusting portions 420 , at least two of the multiple adjusting portions 420 have different lengths along the second direction, and any one of the multiple adjusting portions 420 can be replaceably connected to the fixing portion 410 .

As shown in FIG18 , one end of the fixing portion 410 can be connected to the second door body 200, and the other end of the fixing portion 410 is provided with a latching protrusion. The adjusting portion 420 is provided with a latching slot. The fixing portion 410 is secured to the adjusting portion 420 by the latching protrusion and the latching slot. A snap-fit ​​structure 416 can also be provided on the latching protrusion and the slot to enhance the connection stability between the fixing portion 410 and the adjusting portion 420.

[0170] It should be noted that the arrow in FIG. 8 indicates that the adjustment portion 420 is assembled to the fixing portion 410 in the direction indicated by the arrow.

[0171] In this embodiment, the fixing portion 410 may be provided with a positioning hole 413 and a fixing hole 415, both of which 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.

[0172] According to some embodiments of the present application, optionally, the door body assembly of this 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 the third direction Z, and the third direction Z is perpendicular to the mounting surface 101.

[0173] The third direction Z corresponds to the thickness direction of the door assembly, which is consistent with the front-to-back direction of the home appliance. The third adjustment member 600 can be disposed on the side of the second adjustment member 400 facing the second door body 200, or on the side of the first adjustment member 300 facing the first door body 100.

[0174] Specifically, in some implementations, the third adjustment member 600 includes multiple shims 610, at least two of which have different thicknesses along the third direction Z. At least one of the multiple shims 610 is positioned between the first adjustment member 300 and the first door body 100 or between the second adjustment member 400 and the second door body 200. By selecting shims 610 of varying thicknesses, the relative positions of the first door body 100 and the second door body 200 in the third direction Z can be adjusted. As shown in FIG. 15 , in some embodiments, the shims 610 can be provided with holes that correspond one-to-one with the fixing holes 415 in the fixing portion 410, thereby enabling the fixing portion 410 and the shims 610 to be secured to the second door body 200 via fasteners.

[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 shown in Figures 13 and 14, the thickness of the second adjusting member 400 along the third direction Z is C. A gasket 610 is provided on the side of the second adjusting member 400 facing the second door body 200. The dimension between the second adjusting member 400 and the gasket 610 is C1. The gasket 610 can be used to adjust the thickness of the second adjusting member 400 along the third direction Z, thereby adjusting the relative position of the second door body 200 with respect to the first door body 100 in the third direction Z. It is 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 create a variety of second adjusting members 400 with different thicknesses.

[0176] It should be noted that the gasket 610 is usually arranged to correspond 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 .

[0177] In 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 is disposed on the second base 620 , and is adjustable relative to the second base 620 along the third direction Z.

[0178] 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 primary description. As shown in FIG19 , 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. The fixing portion 410 is positionally adjustable on the second base 620 along the third direction Z. The fixing portion 410 may be provided with a first thread, and the second base 620 may be provided with a second thread. The first thread engages with the second thread, and the axis of the first thread and the second thread extends along the third direction Z. By rotating the fixing portion 410 relative to the second base 620, the fixing portion 410 can move relative to the second base 620 along the third direction Z due to the threaded engagement, thereby adjusting the relative position of the fixing portion 410 relative to the second base 620 in the third direction Z.

[0179] Specifically, as shown in FIG19 , 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. 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. By rotating the fixing portion 410 relative to the threaded column 621 along the rotation direction D, the position of the fixing portion 410 on the threaded column 621 can be adjusted. It should be noted that, in addition to being provided with external threads, the second base 620 can also cooperate with the fixing portion 410 to form an installation limit structure. For details, please refer to the description 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 adjustment of the relative position of the fixing part 410 in the second direction, the second base 620 can be rotated relative to the fixing part 410, 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 can be 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.

[0180] 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.

[0181] It should be noted that the two second adjusting members 400 spaced apart along the first direction refer to a state in which the second adjusting members 400 are disposed on the second door body 200. That is, as shown in Figures 1, 2, 7, and 8, a plurality of second adjusting members 400 sequentially disposed 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.

[0182] According to some embodiments of the present application, optionally, along the second direction, at least two first adjustment members 300 are provided on the mounting surface 101 at intervals, and at least one of the at least two first adjustment members 300 is matched with a second adjustment member 400 .

[0183] In this embodiment, as shown in Figures 1, 2, 7 and 8, 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 be matched with a second adjusting member 400, and each first adjusting member 300 can be matched with multiple second adjusting members 400 along the first direction.

[0184] It is understandable that as long as there is a first adjusting member 300 that is matched with the second adjusting 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 adjusting members 300 to be matched with the second adjusting member 400 provided in this embodiment. In some embodiments, some of the first adjusting members 300 can be configured with a slide 430 that only has a sliding function, and the slide 430 is connected to the second door body 200 to play a guiding role. In this embodiment, the number of first adjusting members 300 includes two arranged along the height direction Y. As shown in Figure 2, the second adjusting member 400 is only provided in the position corresponding to the upper first adjusting member 300 in the second door body 200, and the slide 430 is provided in the position of the second door body 200 corresponding to the lower second adjusting member 400.

[0185] According to some embodiments of the present application, the door assembly may further include a second door 200, which is connected to the second adjusting member 400. The first door 100 is a door of the refrigeration appliance and the second door 200 is a cabinet door, or the first door 100 is a cabinet door and the second door 200 is a door of the refrigeration appliance, and the refrigeration appliance is used to be arranged in the cabinet.

[0186] The refrigeration appliance can be a refrigerator, and the refrigerator door body 10 can be in the form of all storage spaces opening and closing through the overall door body, or can be in the form of a plurality of independently opening and closing door bodies, for example, the refrigerator compartment has an independent door body, and the freezer compartment has an independent door body, and the refrigerator compartment door body and the freezer compartment door body are separate and independent of each other, and can be controlled to open or close separately. In this embodiment, the independently opening door bodies of the refrigerator can all be refrigerator doors 10, that is, a cabinet panel 20 can 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 multiple independently set door bodies, there are also multiple cabinet panels 20, and the cabinet panels 20 are provided in a one-to-one correspondence with the refrigerator door bodies 10. When the refrigerator has multiple independently set 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.

[0187] The thickness of the cabinet door along the third direction Z ranges from 6 mm to 30 mm. Specifically, along the third direction Z, the thickness of the cabinet panel 20 ranges from 6 mm to 12 mm, or, along the third direction Z, the thickness of the cabinet panel 20 ranges from 15 mm to 25 mm.

[0188] Specifically, the thickness of the cabinet board 20 can be 6 mm, 9 mm, or 12 mm. The thickness of the cabinet board 20 can also be 15 mm, 18 mm, or 25 mm.

[0189] In some embodiments, the thickness of the cabinet panel 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. Both 9 mm or about 9 mm and 18 mm or about 18 mm can be understood as dimensions within the processing error range allowed by the process when processing a cabinet panel 20 of standard size, taking 9 mm or 18 mm as the standard size.

[0190] 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.

[0191] 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 panel 20 and the refrigerator door body 10 (i.e., between the first door body 100 and the second door body 200), it is usually difficult to achieve a gap 30 between the cabinet panel 20 and the refrigerator door body 10. However, 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, or 4.5 mm, so that the thickness space occupied by the door assembly is small, thereby improving the user experience and space utilization.

[0192] Specifically, as shown in Figures 3 and 4, 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. This can not only make the thickness space occupied by the door body assembly smaller, but also save consumables. It should be noted that, as shown in Figure 3, when the thickness T of the first adjusting member 300 and the second adjusting member 400 along the third direction Z after assembly is greater than the gap set between the first door body 100 and the second door body 200, the first adjusting member 300 and the second adjusting member 400 can be installed through the mounting groove 350 by opening a mounting groove 350 on the surface of the first door body 100 and the second door body 200. 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.

[0193] In this embodiment, after the first door body 100 and the second door body 200 are adjusted into place in any direction through 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 using the fixing member 700.

[0194] Specifically, as shown in Figures 20 to 22, the door body assembly also includes a fixing member 700, which 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 bar hole, and the position of the columnar fastener cooperating with the bar hole is adjustable along the length direction of the bar hole.

[0195] The cylindrical fastener can be a screw, and the cooperation between the cylindrical fastener and the first mounting hole 730 can be that one end of the cylindrical fastener passes through the first mounting hole 730 to connect with the first door body 100, and the other end of the cylindrical fastener presses against the first connecting plate 710; the cooperation between the cylindrical fastener and the second mounting hole 740 can be that one end of the cylindrical fastener passes through the second mounting hole 740 to connect with the second door body 200, and the other end of the cylindrical fastener presses against the second connecting plate 720. The length direction of the strip hole refers to the direction in which the strip hole extends the longest in a direction perpendicular to its own axis. The strip hole makes the setting position of the cylindrical fastener more flexible, facilitating the assembly and fixation of the first door body 100 and the second door body 200.

[0196] The first connecting plate 710 and the second connecting plate 720 may be coplanarly connected or intersectingly connected, 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.

[0197] 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.

[0198] 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 in the direction from the first end to the second end. The columnar fastener is passed through the strip hole to fix the first connecting plate 710 to the first door body 100. The columnar fastener can move in the strip hole along the length direction of the strip hole.

[0199] The following describes the fixing member 700 in detail, taking the connection of the first connecting plate 710 to the refrigerator door 10 and the connection of the second connecting plate 720 to the cabinet panel 20 as an example. As shown in Figures 20 to 22, the cabinet panel 20 can be slightly wider than the width of the refrigerator door 10 in the width direction X. The fixing member 700 is disposed at one end of the refrigerator door 10 in the width direction X and is located on the inner side of the cabinet panel 20 where it is wider than the refrigerator door 10. In this way, the first connecting plate 710 can be aligned and connected to the end of the refrigerator door 10 in the width direction X, and the second connecting plate 720 can be aligned and connected to the inner side of the cabinet panel 20. In some implementations, as shown in Figures 20 and 21, the end of the refrigerator door 10 in the width direction X can be provided with a mounting groove, and the first connecting plate 710 can be disposed in the mounting groove. The second connecting plate 720 may be provided with one or two second mounting holes 740, through which cylindrical fasteners (e.g., screws) pass to connect the second connecting plate 720 to the refrigerator door 10. The first connecting plate 710 is provided with a strip hole extending along the third direction Z. The cylindrical fasteners, such as screws, pass through the strip hole to connect the first connecting plate 710 to the refrigerator door 10. Because the strip hole has a certain adjustment space in the third direction Z, the fit between the first door 100 and the second door 200 in the third direction Z is less demanding, thereby increasing the assembly flexibility of the fixing member 700.

[0200] Some embodiments of the present application also provide a household appliance, including an appliance body and a door 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, and the door assembly is connected to the appliance body and is arranged at the opening so as to be openable and closable.

[0201] 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 device assembled with a cabinet and an embedded refrigeration appliance, 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 arranged at the opening of the refrigeration appliance body for sealing the refrigeration appliance body, and the other corresponds to the opening of the cabinet body.
