[0096] A door shelf is usually installed on the door of a refrigerator, and the aesthetic level thereof directly affects the interior decoration effect of the whole refrigerator. In order to improve the decoration and the structural strength, some door shelves adopt a double-layer wall thickness structure, but there are problems of a large number of parts and poor stability.

[0097] Therefore, the door shelf assembly provided by the utility model has the advantages that the door shelf is arranged in the accommodating cavity formed in the outer frame, so that the bottom wall and the side wall of the door shelf assembly have a double-layer wall thickness structure, the modeling is more solid and tangible, the number of parts is small, the structural strength of the door shelf assembly is improved, and the appearance of the outer frame can be processed more to improve the aesthetic property. In addition, the limiting structure is arranged between the outer frame and the door shelf, the limiting structure comprises a buckle structure, the assembly process of the outer frame and the door shelf is simple, the assembly efficiency is improved, the accuracy of the relative position of the door shelf and the outer frame is ensured, and unnecessary movement or overturning of the door shelf in use is prevented.

[0098] In order to facilitate the introduction of the door shelf assembly provided by the utility model, a three-dimensional coordinate system is established, as shown in Figure 1 , the X axis is the width direction of the door body and the left-right direction of the door shelf assembly, the direction indicated by the +X axis is the right end; the Y axis is the thickness direction of the door body and the front-rear direction of the door shelf assembly, the direction indicated by the +Y axis is the front end; and the Z axis is the height direction of the door body and the up-down direction of the door shelf assembly, the direction indicated by the +Z axis is the upper end. Among them, the included angle between any two axes of the X axis, the Y axis and the Z axis is 90°.

[0099] As shown in Figure 1 , Figure 2 and Figure 3 , the utility model provides a refrigerator, which comprises a door body, an inner wall of the door body is provided with a door shelf assembly, and the door shelf assembly comprises:

[0100] an outer frame 10, the outer frame 10 comprises a bottom plate 12 and side plates 13 connected to opposite ends of the bottom plate 12, so as to form an accommodating cavity 11 in the outer frame 10;

[0101] a door shelf 20 arranged in the accommodating cavity 11;

[0102] a limiting structure arranged between the outer frame 10 and the door shelf 20, and configured to limit the relative position of the door shelf 20 and the outer frame 10;

[0103] the limiting structure comprises a buckle structure, the side plates 13 and the door shelf 20 are connected through the buckle structure to prevent the relative overturning movement of the side plates 13 and the door shelf 20.

[0104] The utility model provides a refrigerator, door shelf subassembly includes outer frame 10 and door shelf 20, forms the accommodation cavity 11 in the inside of outer frame 10 with the door shelf 20 setting, make the bottom wall and the lateral wall of door shelf subassembly present the structure of double -layer wall thickness, modelling is more solid and tangible, less spare parts, less appearance splicing line, on one hand can improve the structural strength of door shelf subassembly, on the other hand, it is convenient to handle more for the appearance of outer frame 10, improve the aesthetic property.

[0105] In addition, by setting the limiting structure between outer frame 10 and door shelf 20, the assembly process of outer frame 10 and door shelf 20 is simple, the assembly efficiency is improved, the accuracy of the relative position of door shelf 20 and outer frame 10 is ensured, and unnecessary movement or overturning of door shelf 20 in the use process is prevented. The limiting structure includes a buckle structure, which provides a simple and effective way to prevent the relative overturning movement of side plate 13 and door shelf 20, thereby increasing the stability and safety of the entire door shelf subassembly and reducing the problem of falling of the objects placed in door shelf 20.

[0106] In one possible implementation, outer frame 10 can be an integral structure formed in one piece, which can be made of plastic material.

[0107] Before assembling with door shelf 20, outer frame 10 is convenient for being subjected to various surface treatments such as etching and frosting separately, so that the appearance of outer frame 10 is more diversified and the decorative aesthetic effect is improved.

[0108] Etching treatment usually involves chemical or physical methods to remove a portion of the material surface to form a specific pattern or texture, which can achieve high precision and complex patterns, and etching treatment can also reduce surface reflection and improve product performance under different lighting conditions, thereby improving the appearance of the surface. Chemical etching uses acid or other chemical reagents.

[0109] Frosting treatment is usually achieved by sandblasting, acid etching or using frosting paste, which makes the material surface opaque or translucent, not only improving the texture of the product, but also increasing its slip resistance and wear resistance.

[0110] Since outer frame 10 includes bottom plate 12 and side plates 13 connected to opposite ends of bottom plate 12 to form accommodation cavity 11 inside outer frame 10, the front and rear ends and the top end of outer frame 10 form openings communicating with accommodation cavity 11, and door shelf 20 can be slidingly arranged in accommodation cavity 11 along the front-rear direction, during production and assembly, door shelf 20 can be pushed into accommodation cavity 11 from the opening at the rear end of outer frame 10 along the front-rear direction, realizing quick installation and disassembly of door shelf 20 and outer frame 10, and providing a reliable and stable structure.

[0111] In a possible implementation, the door shelf 20 is substantially cuboid, and the door shelf 20 has a storage cavity 23 for placing articles. In order to facilitate the placing of articles into the storage cavity 23, the top of the door shelf 20 is open, so that the user can take or place articles in the storage cavity 23.

[0112] In a possible implementation, the outer frame 10 includes a bottom plate 12 and side plates 13 connected to opposite ends of the bottom plate 12. In use, the top of the two side plates 13 is prone to turn outward, causing the two side plates 13 to separate from the outer side wall of the door shelf 20, affecting the stability of use. Therefore, in the present application, a buckle structure is arranged between the top of the two side plates 13 and the outer side wall of the door shelf 20. The buckle structure is simple in design and easy to assemble and disassemble, which not only improves the production efficiency, but also improves the stability of the connection, reduces the phenomenon that the two side plates separate from the outer side wall of the door shelf 20 due to external force or vibration in use, effectively prevents the problem of outward turning of the two side plates 13, and makes the door shelf assembly safer and more durable in use.

[0113] In a possible implementation, referring to Figure 4 、 Figure 5 and Figure 6 , the buckle structure includes a first buckle unit 41. The front end of the side plate 13 has a side stop rib 321. The first buckle unit 41 includes:

[0114] a first clamping portion 411 arranged on the opposite two outer side walls of the door shelf 20;

[0115] a second clamping portion 412 arranged on the side of the side stop rib 321 facing the accommodation cavity 11. The second clamping portion 412 and the first clamping portion 411 are buckled with each other to prevent the door shelf 20 from separating from the side plate 13.

[0116] Such a structure, referring to Figure 6 、 Figure 7 and Figure 8 , the first clamping portion 411 and the second clamping portion 412 are buckled with each other to achieve stable connection, which can effectively prevent the second clamping portion 412 from separating from the first clamping portion 411, thereby ensuring that the door shelf 20 can be stably attached to the front end of the side plate 13 and improving the stability of use.

[0117] In the present example, the front end of the side plate 13 is the end of the side plate 13 away from the door body along the Y-axis direction. The rear end of the side plate 13 is the end of the side plate 13 close to the door body along the Y-axis direction.

[0118] In one possible implementation, one of the second engaging portion 412 and the first engaging portion 411 is a clamping groove, and the other is a clamping protrusion. By extending the clamping protrusion into the clamping groove, the second engaging portion 412 and the first engaging portion 411 are engaged with each other, thereby providing a stable connection effect.

[0119] In this example, the clamping groove is generally a recessed structure designed to accommodate the size and shape of the clamping protrusion. The depth and width of the clamping groove are precisely designed to ensure that the clamping protrusion can be smoothly inserted and stably retained. The clamping protrusion is generally a protruding structure that matches the shape and size of the clamping groove. The design of the clamping protrusion takes into account the convenience of insertion and removal, while ensuring that sufficient retention force is provided after engagement. When the clamping protrusion extends into the clamping groove, the inner wall of the clamping groove tightly contacts the outer surface of the clamping protrusion, achieving mechanical locking. This engagement provides strong pull-out resistance, ensuring that the door shelf 20 can be stably attached to the side plate 13 and will not easily separate during use.

[0120] In one possible implementation, referring to Figure 5 , Figure 6 and Figure 7 , the opposite two outer side walls of the door shelf 20 are provided with turned-up edges 24, and the clamping structure further includes a second clamping unit 42, which includes:

[0121] a first engaging portion 421 provided at the rear end of the side plate 13;

[0122] a second engaging portion 422 provided at the turned-up edge 24, and the second engaging portion 422 is engaged with the first engaging portion 421. With this structure, the second engaging portion 422 and the first engaging portion 421 are engaged with each other, improving the stability of the door shelf 20 attached to the rear end of the side plate 13, avoiding deformation of the side plate 13 due to heavy loads and other factors, and affecting use.

[0123] In one possible implementation, one of the second engaging portion 422 and the first engaging portion 421 is a clamping groove, and the other is a clamping protrusion. By extending the clamping protrusion into the clamping groove, the second engaging portion 412 and the first engaging portion 411 are engaged with each other, thereby providing a stable connection effect. When the second engaging portion 422 and the first engaging portion 421 are engaged with each other, i.e., the clamping protrusion extends into the clamping groove, the clamping groove tightly surrounds the clamping protrusion. This engagement provides a mechanical locking effect, ensuring the stability of the door shelf 20 attached to the rear end of the side plate 13, and will not easily separate during use.

[0124] The first buckle unit 41 can effectively prevent the outer side wall of the door shelf 20 from being separated from the front end of the side plate 13, and the second buckle unit 42 can effectively prevent the outer side wall of the door shelf 20 from being separated from the rear end of the side plate 13, so that the side plate 13 can be stably attached to the outer side wall of the door shelf 20, the side plate 13 is prevented from being turned outward, and the door shelf 20 is also prevented from being accidentally slid out or falling off during use, thereby reducing the deformation of the outer frame 10 and improving the stability of use.

[0125] In a possible implementation manner, the front end of the side plate 13 is provided with a side blocking rib 321, which can be inclinedly extended into the accommodating cavity 11 and be tightly attached to the door shelf 20, thereby improving the aesthetic appearance of the outer appearance.

[0126] In a possible implementation manner, the height of the side blocking rib 321 is consistent with the height of the side plate 13, so that the side blocking rib 321 can effectively block the edge of the front end of the door shelf 20, thereby improving the aesthetic appearance.

[0127] In a possible implementation manner, referring to Figure 2 , Figure 10 and Figure 11 , the limiting structure further includes a first limiting unit 31 for limiting the door shelf 20 to move in the height direction of the door body, that is, in the Z-axis direction, in the accommodating cavity 11, and the first limiting unit 31 includes:

[0128] an inwardly turned edge 311 connected to the inner wall of the side plate 13, and the top of the door shelf 20 abuts against the inwardly turned edge 311;

[0129] a convex rib 312 arranged on the inner bottom wall of the bottom plate 12, and the bottom wall of the door shelf 20 abuts against the convex rib 312.

[0130] In a possible implementation manner, the inwardly turned edge 311 is located at the top of the side plate 13 and is inwardly turned towards the accommodating cavity 11. Arranging the inwardly turned edge 311 can also improve the structural strength of the outer frame 10 and prevent the outer frame 10 from being deformed.

[0131] The top of the door shelf 20 abuts against the inwardly turned edge 311, which can effectively prevent the top of the door shelf 20 from being separated from the outer frame 10, and the bottom wall of the door shelf 20 abuts against the convex rib 312. Through the blocking effect of the bottom plate 12 and the convex rib 312 on the bottom wall of the door shelf 20, the stability of the door shelf 20 in the up-down direction in the accommodating cavity 11 is ensured.

[0132] In a possible implementation manner, referring to Figure 1 and Figure 16As shown, the outer bottom wall of the door shelf 20 is flat, and has a large area. In order to avoid the problem of poor assembly caused by the contact between the outer bottom wall of the door shelf 20 and the inner bottom wall of the bottom plate 12, a protruding rib 312 is arranged on the inner bottom wall of the bottom plate 12, so that the bottom wall of the door shelf 20 abuts against the protruding rib 312, which can reduce the machining precision requirement of the outer bottom wall of the door shelf 20 and prevent the problem of installation difficulty.

[0133] In a possible implementation manner, referring to Figure 2 and Figure 15 As shown, the protruding rib 312 protrudes from the inner bottom wall of the bottom plate 12 by a certain height, and the protruding rib 312 can extend along the front-rear direction. The number of the protruding ribs 312 is multiple, and the multiple protruding ribs 312 can be distributed at intervals.

[0134] In a possible implementation manner, referring to Figure 4 , Figure 5 and Figure 6 As shown, the limiting structure further includes a second limiting unit 32 for limiting the movement of the door shelf 20 in the thickness direction of the door body, i.e., along the Y-axis direction, in the accommodating cavity 11. The second limiting unit 32 includes:

[0135] A stop buckle 322 arranged on the opposite two outer side walls of the door shelf 20;

[0136] A stop protrusion 323 arranged on the side of the side plate 13 facing the door shelf 20, and the stop buckle 322 and the stop protrusion 323 are buckled with each other.

[0137] Such a structure can provide a limiting function in the front-rear direction when the door shelf 20 is installed in place in the accommodating cavity 11, and the stop buckle 322 and the stop protrusion 323 are buckled with each other, which can prevent unnecessary movement of the door shelf 20 during use and improve the overall firmness.

[0138] In a possible implementation manner, the stop buckle 322 has elasticity and can be deformed towards the direction close to the door shelf 20, which means that the stop buckle 322 can also be deformed when a force is applied, so as to facilitate the disassembly of the door shelf 20 from the accommodating cavity 11 of the outer frame 10 during maintenance.

[0139] In the example, the stop buckle 322 is in the shape of a hook, which can be flexibly matched with the stop protrusion 323. The main function of the stop buckle 322 is to hook on the stop protrusion 323, so as to achieve a locking effect and prevent the door shelf 20 from moving backward.

[0140] In a possible implementation manner, referring to Figure 4 and Figure 9As shown, the second limiting unit 32 further comprises a hook 324 and a protrusion 325, the hook 324 is arranged at the rear end of the bottom plate 12, the protrusion 325 is arranged at the rear end of the bottom of the door shelf 20, and the protrusion 325 extends into the hook 324. The hook 324 tightly surrounds the protrusion 325, and this buckling mode can enhance the stability and firmness of the connection, prevent the bottom plate 12 from separating from the bottom surface of the door shelf 20 during use, and ensure that the bottom plate 12 remains in close contact with the door shelf 20.

[0142] When the door shelf 20 is installed into the accommodation cavity 11 and installed in place, the protrusion 325 extends into the hook 324, which not only can realize the limiting function of the door shelf 20 in the front-rear direction, but also can prevent the rear end of the bottom plate 12 from being turned downward, thereby improving the stability of the door shelf assembly during use.

[0143] In a possible implementation manner, the second limiting unit 32 further comprises a side blocking rib 321 arranged at the front end of the side plate 13 and a lower blocking rib 326 arranged at the front end of the bottom plate 12, and the front end of the door shelf 20 abuts against the side of the lower blocking rib 326 facing the accommodation cavity 11. Through the blocking effect of the side blocking rib 321 and the lower blocking rib 326 on the front end of the door shelf 20, the forward movement of the door shelf 20 can be limited. In addition, the blocking rib 326 blocks the front end of the door shelf 20, which can effectively block the joint gap between the door shelf body 21 and the bottom of the front panel 22, reduce the joint gap of the appearance surface, and improve the appearance beauty.

[0144] In a possible implementation manner, the length of the lower blocking rib 326 is consistent with the length of the bottom plate 12, the two ends of the lower blocking rib 326 are respectively connected to the bottom ends of the two side blocking ribs 321, and the lower blocking rib 326 extends obliquely toward the accommodation cavity 11.

[0145] In a possible implementation manner, referring to Figure 10 and Figure 12 As shown, the limiting structure further comprises a third limiting unit 33, the third limiting unit 33 is used for limiting the movement of the door shelf 20 in the width direction of the door body in the accommodation cavity 11, that is, in the X-axis direction, and the third limiting unit 33 comprises:

[0146] A limiting rib plate 331, the limiting rib plate 331 is arranged at the opposite two outer side walls of the door shelf 20, and the side plate 13 abuts against the limiting rib plate 331. Thus, the position of the door shelf 20 in the accommodation cavity 11 is limited, and the movement of the door shelf 20 in the left-right direction in the accommodation cavity 11 is prevented.

[0147] In a possible implementation, the limiting rib plate 331 protrudes from the outer side wall of the door shelf 20, and the limiting rib plate 331 can extend along the height direction of the door shelf 20, so as to ensure the structural strength of the limiting rib plate 331 itself.
