[0062] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0063] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0064] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0065] Currently, refrigerators with decorative parts on the door frame on the market mostly have the frame assembly solution of first pasting the decorative parts onto the door glass, then assembling the upper and lower end covers, and finally assembling the uprights. This is different from the conventional door glass pressing process, resulting in low production efficiency. Moreover, the uprights and the decorative strips are rotated and snapped together on one side, and a sufficiently large clearance needs to be reserved between the decorative strips and the uprights, which makes it easy for gaps to appear on the side when the foam is applied.

[0066] This utility model proposes a column structure 100, a door assembly 200, and a refrigerator, which are designed to be assembled using a pressing process. During the pressing process, the probability of the decorative part 2 deforming under pressure and causing a gap in the side opening of the column structure 100 is reduced.

[0067] It should be noted that the column 1 is set as a strip. The first direction refers to the length direction of the column 1, which corresponds to the length direction of the door assembly 200. The second direction refers to the height direction of the column 1, which corresponds to the thickness direction of the door assembly 200. When the door assembly 200 is in the closed state, with the user as a reference, the second direction is the front-back direction. The third direction refers to the width direction of the column 1, which corresponds to the thickness direction of the door assembly 200. When the door assembly 200 is in the closed state, with the user as a reference, the second direction is the left-right direction.

[0068] Please see Figures 1 to 4In this utility model, the column structure 100 is used as the door assembly 200 on a refrigerator. The column structure 100 includes a column 1, a decorative piece 2, and a support piece 3. The column 1 extends along a first direction and has a first end 11 and a second end 12 opposite to each other in a second direction. The decorative piece 2 is disposed at the first end 11 of the column 1. The decorative piece 2 has a contact surface 21 and a support surface 22 opposite to each other in the second direction. The contact surface 21 is exposed on the side of the first end 11 facing away from the second end 12, so as to allow the pressing piece 202 to press and attach it along the direction from the first end 11 toward the second end 12. The support piece 3 is supported between the support surface 22 of the decorative piece 2 and the second end 12 of the column 1.

[0069] The technical solution of this utility model increases the connection strength between the decorative part 2 and the column 1 by adopting the arrangement of supporting the support member 3 on the support surface 22 and the second end 12 of the column 1. The support member 3 and the decorative part 2 have greater overall rigidity in the second direction, and the pressing part 202 can be pressed and bonded to the bonding surface 21 by a pressing process. This reduces the probability of the decorative part 2 being deformed due to pressure during the pressing process, thereby reducing the probability of side openings and seams in the column structure 100.

[0070] The support member 3 is positioned between the support surface 22 of the decorative member 2 and the second end 12 of the column 1. The shapes of the decorative member 2 and the column 1 directly determine the connection method of the support member 3. The column 1 can be a solid column, and the decorative member 2 can protrude laterally from the column 1. In this case, the support member 3 can be positioned on the side of the column 1. A connecting structure is also needed between the support member 3 and the column 1 to achieve the connection, such as a threaded connection, a snap-fit ​​connection, or an elastic connection. Alternatively, no connecting structure may be needed between the support member 3 and the decorative member 2; a direct support method can be used.

[0071] In some embodiments, the column 1 is configured as a hollow column, the decorative element 2 can be partially inserted into the hollow column, and the support element 3 can be disposed in the hollow column. On the one hand, the support element 3 can be installed directly opposite the decorative element 2, which facilitates the transmission of the pressing force; on the other hand, disposing of the support element 3 in the hollow column reduces the need for additional structural settings to limit the support element 3, thus simplifying the structure.

[0072] Specifically, the column 1 has an opening 13 on one side in the third direction. The decorative part 2 extends at least partially into the column 1 through the opening 13, so that the supporting surface 22 of the decorative part 2 is inside the column 1. The support 3 is supported inside the column 1. By placing the support 3 inside the column 1, when the pressing part 202 is pressed and installed on the decorative part 2 in the second direction, the pressing force can be well transmitted to the decorative part 2 in the second direction, reducing the probability of the decorative part 2 being deformed due to pressure during the pressing process, and thus reducing the probability of the side opening of the column structure 100 having a gap.

[0073] It is understood that the fact that the bonding surface 21 is exposed on the side of the first end 11 facing away from the second end 12 means that the bonding surface 21 is not obstructed, the bonding surface 21 can directly contact the pressing member 202, and the pressing member 202 can completely cover the bonding surface 21. The decorative member 2 protrudes outward from one end near the column 1 along the second direction and forms a smooth curved surface, thereby beautifying the junction between the pressing member 202, the decorative member 2, and the column 1, serving as a decorative finish.

[0074] The specific cross-sectional shape of the column 1 is not limited; it can be circular, square, or rectangular, etc. In some embodiments, the column 1 has a first column wall portion 14 opposite to the decorative element 2 in a second direction, and a second column wall portion 15 connected to the first column wall portion 14 and located in a third direction. The second column wall portion 15 is disposed opposite to the opening 13, wherein the support member 3 is supported between the decorative element 2 and the first column wall portion 14. By placing the support member 3 between the decorative element 2 and the first column wall portion 14, the structural strength at the joint between the decorative element 2 and the column 1 is enhanced, thereby reducing the possibility of the decorative element 2 loosening or falling off due to external forces (such as pressure or collision), and improving the overall safety and reliability. In addition, the opening 13 facilitates the installation and use of the support member 3, improving the flexibility of the column structure 100.

[0075] The column 1 can be integrally formed, for example, by stamping, which simplifies the forming process; of course, in some other embodiments, the column 1 can also be welded.

[0076] Since the support member 3 may slide along the width direction of the column 1, reducing the connection strength between the support member 3, the decorative member 2, and the column 1, in some embodiments, the side surface of the support member 3 is adhered to the second column wall portion 15. Adhering the support member 3 to the second column wall portion 15 improves the robustness of the connection between the column 1 and the support member 3. Furthermore, the adhesive method allows for adjustment of the position and angle of the support member 3 as needed to adapt to different design requirements and functional needs, improving flexibility. The support member 3 can be adhered using glue, tape, or hot melt adhesive.

[0077] Specifically, in some embodiments, foam is provided on the side surface of the support member 3 and bonded to the second column wall portion 15. The foam has good elasticity and energy absorption characteristics, which can effectively absorb the impact and vibration between the support member 3 and the decorative member 2, thereby further improving the reliability of the connection between the two.

[0078] The support member 3 may detach from the decorative member 2 and the column 1 in the third direction (i.e., the width direction of the column 1). Therefore, the support member 3 needs to be limited in the third direction.

[0079] Specifically, in some embodiments, the column 1 has a third column wall portion 16 located at the second end 12 and facing the third direction, and the opening 13 is defined between the third column wall portion 16 and the first end 11 of the column 1; the third column wall portion 16 is used to limit and abut against the side end of the support member 3. By providing the third column wall portion 16, the side end of the support member 3 is limited, thereby limiting the support member 3 within the column 1, reducing the movement of the support member 3, and thus improving the support effect of the support member 3 within the column 1.

[0080] In the technical solution of this utility model, the size (length, width, and height) of the third column wall portion 16 is not specifically limited and can be set according to the actual needs. Of course, considering that the support member 3 needs to extend into the column 1 through the opening 13, in order to facilitate the installation and use of the support member 3, the dimension of the third column wall portion 16 along the second direction should not be too high.

[0081] The decorative element 2 is located at the first end 11 of the column 1. The installation method between the two is not limited. It can be a screw connection, for example, using a screw to be screwed into a pre-drilled threaded hole in the column 1 through a hole provided on the decorative element 2 to complete the fixed connection between the decorative element 2 and the column 1; it can also be an insertion connection, for example, an insertion part is provided in the decorative element 2, which can be inserted into a reserved slot in the column 1; it can also be a magnetic connection, with magnets embedded in the interior or surface of the decorative element 2 and the column 1, and fixed by magnetic force.

[0082] To improve the connection stability between the column 1 and the decorative element 2 while simplifying the installation structure, in some embodiments, a snap-fit ​​groove 24 is provided on the side end of the decorative element 2; the column 1 is hollow and has a fourth column wall portion 17 located at the first end 11 and in the second direction, which snaps into the snap-fit ​​groove 24. The snap-fit ​​groove 24 allows the fourth column wall portion 17 to connect to the decorative element 2, thereby snapping the column 1 and the decorative element 2 together, achieving a stable installation of the column 1 and the decorative element 2 without the need for additional fasteners or connectors, thus simplifying the installation process.

[0083] Through the cooperation of the snap-fit ​​groove 24 and the fourth column wall portion 17, the column 1 and the decorative part 2 are mutually restricted in the second direction. In the third direction, the column 1 and the decorative part 2 are still at risk of relative movement and separation, so further restriction is required in the third direction.

[0084] In some embodiments, one of the sidewalls of the snap-fit ​​groove 24 along the second direction and the fourth column wall portion 17 is provided with a second limiting protrusion 6, and the other is provided with a second mating recess 7. The second limiting protrusion 6 is at least partially contained within the second mating recess 7. Through the convex-concave fit between the second limiting portion and the second mating recess 7, when the column 1 is snapped into the decorative piece 2 through the snap-fit ​​groove 24, the column 1 and the decorative piece 2 are limited and prevented from detaching in the third direction, thereby improving the stability of the column 1 installed within the decorative piece 2.

[0085] The second limiting part and the second mating recess 7 can be configured as a keyway and a key; or as a shaped boss and a shaped groove; or as a T-shaped boss and a T-shaped groove. At least a portion of the second limiting protrusion 6 can be contained within the second mating recess 7 to fix the relative position between the column 1 and the decorative piece 2; or the entire second limiting protrusion 6 can be contained within the second mating recess 7 to achieve a tight fit.

[0086] To allow the column 1 to be inserted and installed into the bottom of the slot 24 through the opening, in some embodiments, the width of the slot 24 gradually increases along the direction from the opening of the slot to its bottom. The decorative element 2 can be a tensioned elastic element, and when the column 1 is engaged with the decorative element 2 through the slot 24, the opening of the slot 24 can open to allow the column 1 to be inserted and engaged.

[0087] The decorative element 2 is subjected to pressure from the pressing member 202 in the second direction (i.e., the height direction of the column 1), while the support member 3 experiences uneven force in the third direction (i.e., the width direction of the column 1), potentially causing the support member 3 to detach from the decorative element 2 and the column 1. In some embodiments, one of the supporting surface 22 of the decorative element 2 and the end face of the support member 3 opposite to the decorative element 2 is provided with a first limiting protrusion 4, and the other is provided with a first mating recess 5. The first limiting protrusion 4 is at least partially contained within the first mating recess 5. The provision of the first limiting protrusion 4 and the first mating recess 5 allows the support member 3 to extend into the column 1, supporting the decorative element 2 through a convex-concave fit, thereby providing further support and limitation for the installation of the support member 3 within the column 1 and improving support strength.

[0088] It is understood that the first limiting protrusion 4 can be positioned on the support surface 22 of the decorative element 2, that is, a first mating recess 5 can be provided in the end face of the support element 3 opposite to the decorative element 2, with the first limiting protrusion 4 and the first mating recess 5 engaging in a convex-concave fit to complete the connection between the support element 3 and the decorative element 2 bracket; or the first limiting protrusion 4 can be provided in the end face of the support element 3 opposite to the decorative element 2, and the first mating recess 5 can be provided on the support surface 22 of the decorative element 2, with the first limiting protrusion 4 and the first mating recess 5 engaging in a convex-concave fit to complete the connection between the support element 3 and the decorative element 2 bracket. The convex-concave fit between the first limiting protrusion 4 and the first mating recess 5 can be configured as follows: a circular boss and a circular groove; a square boss and a square groove; or a polygonal boss and a polygonal groove. The first limiting protrusion 4 can be configured in such a way that a portion of the first limiting protrusion 4 is limited and accommodated within the first mating recess 5, thereby fixing the relative position between the support surface 22 of the decorative element 2 and the end face of the support element 3 opposite to the decorative element 2; or, the entire first limiting protrusion 4 can be limited and accommodated within the first mating recess 5 to achieve a tight fit.

[0089] It is understood that the support member 3 can be plate-shaped, such as a support plate, with a large supporting area; it can be column-shaped, such as a support column, with simple materials and convenient installation; or it can be strip-shaped, such as a support strip, with a certain supporting area and flexible use. To further improve the installation strength of the support member 3, in some embodiments, the support member 3 can be set as an extruded part. By setting the support member 3 as an extruded part, it has its own cavity, which can increase the supporting strength of the support member 3, and there is no need to cut grooves or cavities, making materials readily available. Alternatively, multiple first cavities 31 can be provided within the support member 3. The provision of multiple first cavities 31 changes the supporting strength of the support member 3, thereby improving the deformation problem of the connection between the decorative part 2 and the column 1. Alternatively, multiple second cavities 23 can be provided within the decorative part 2, thereby providing a certain supporting strength for the decorative part 2 and improving its resistance to deformation when connected to the column 1 and the support member 3.

[0090] Please see Figures 5 to 6To further improve the connection strength between the decorative element 2 and the column 1, in some embodiments, a plurality of first cavities 31 can be provided in the support element 3, and a plurality of second cavities 23 can be provided in the decorative element 2, wherein at least two of the first cavities 31 are arranged along a second direction. This multi-cavity arrangement can reduce the overall weight of the support element 3, improve material utilization, and maintain sufficient structural strength. Alternatively, a plurality of first cavities 31 can be provided in the support element 3, and a plurality of second cavities 23 can be provided in the decorative element 2, wherein at least two of the second cavities 23 are arranged along a second direction. The provision of the second cavities 23 strengthens the supporting performance of the decorative element 2, thereby providing stable support for the column structure 100. Or, a plurality of first cavities 31 can be provided in the support element 3, and a plurality of second cavities 23 can be provided in the decorative element 2, wherein at least one of the first cavities 31 and at least one of the second cavities 23 are arranged along a second direction. Through the first cavity 31 and the second cavity 23, both of which are arranged along the second direction, the pressure in the second direction generated when the pressing member 202 is pressed can be received through the first cavity and the second cavity, thereby improving the support strength of the support member 3 between the decorative member 2 and the column 1.

[0091] Side gaps result from the relative deformation of the column 1 and the decorative element 2 under stress, causing a failure in their fit. In some embodiments, multiple support members 3 are provided and spaced apart along a first direction. By providing multiple support members 3, multiple support points can be increased to expand the support range, thereby improving the stability of the relative position of the column 1 and the decorative element 2 after assembly.
