Detailed Implementation

[0031] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0033] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] As described in the background section, refrigerator doors typically have shelves on their inner walls for storing beverages, such as wine and drinks, to maximize the refrigerator's capacity. The shelves are adjustable, allowing for adjustments to accommodate items of varying heights. Currently, adjusting the door shelves requires the use of a toothed rack on the door liner. However, prolonged use and wear can cause the exposed toothed rack to accumulate dirt and become discolored. Furthermore, foreign objects can easily fall onto the toothed rack and the transmission mechanism, causing jamming during shelf adjustment.

[0036] To alleviate or solve the above-mentioned technical problems, this utility model proposes a door shelf adjustment structure and a refrigerator. The door shelf adjustment structure includes a door 10, a shelf body 20, an adjustment component 30, a first cover plate 40, and a second cover plate 50. The adjustment component 30 is used to adjust the position of the shelf body 20 in a first direction. The first cover plate 40 is used to cover the transmission component 32 and the limiting part 33 of the adjustment component 30. The second cover plate 50 is used to cover the limiting structure 11 on the door 10. The limiting part 33 and the limiting structure 11 are interlocked. When the position of the shelf body 20 needs to be adjusted, the transmission component 32 drives the limiting part 33 to move, causing the limiting part 33 to disengage from the limiting structure 11. After the shelf body 20 is adjusted to the desired position, the limiting part 33 is inserted into the corresponding position of the limiting structure 11. By setting the first cover plate 40 and the second cover plate 50, at least part of the adjustment component 30 and the limiting structure 11 can be covered, thus reducing the accumulation of dirt and grime and the possibility of foreign objects entering.

[0037] The door shelf adjustment structure provided in the embodiments of this utility model will now be described.

[0038] Please refer to the following: Figures 1 to 5 The door shelf adjustment structure includes:

[0039] The door 10 has a limiting structure 11 set along the first direction Z;

[0040] The shelf body 20 is used to place items, and the shelf body 20 is slidably connected to the box door 10 along the first direction;

[0041] Adjustment component 30 is disposed on shelf body 20. Adjustment component 30 includes a handle 31, a transmission component 32 and a limiting part 33 that are at least partially exposed on shelf body 20. The handle 31, transmission component 32 and limiting part 33 are sequentially connected in a transmission manner. The limiting part 33 is used to interlock with limiting structure 11.

[0042] The first cover plate 40 is used to cover the transmission assembly 32 and the limiting part 33;

[0043] The second cover plate 50 is used to cover the limiting structure 11.

[0044] The door 10 is the door structure of the refrigerator. In order to improve the volume ratio of the refrigerator, the door 10 is generally equipped with a shelf body 20. The door 10 is provided with a limiting structure 11, which is a structure used to limit the position of the shelf body 20 in a first direction. The limiting structure 11 is set along the first direction, which can be understood as the length direction of the limiting structure 11 being the first direction.

[0045] The shelf body 20 is used to place items and increase the usable space inside the refrigerator. The shelf body 20 can slide on the door 10 in a first direction to adjust the position of the shelf body 20.

[0046] The adjustment component 30 is disposed on the shelf body 20, meaning that at least a portion of the adjustment component 30 is mounted on the shelf body 20. A handle 31 is provided for user operation. The handle 31 of the adjustment component 30 is generally a manually operable structure, used to control the movement of the transmission component 32 and the limiting part 33. The transmission component 32 connects the movement of the handle 31 and the limiting part 33, transmitting the movement of the handle 31 to the limiting part 33. The limiting part 33 is used to engage with the limiting structure 11. When the limiting part 33 and the limiting structure 11 are engaged, the shelf body 20 is stably positioned at the corresponding position of the cabinet door 10. At least a portion of the handle 31 of the adjustment component 30 is exposed outside the shelf body 20, allowing the user to operate the exposed shelf body 20 and thus control the movement of the transmission component 32 and the limiting part 33.

[0047] When the position of the shelf body 20 needs to be adjusted, the handle 31 drives the limiting part 33 to move, causing the limiting part 33 to disengage from the limiting structure 11. The shelf body 20 is moved in the first direction. When the shelf body 20 is adjusted to the predetermined position, the handle 31 is released, and the limiting part 33 is inserted into the limiting structure 11, so that the shelf body 20 is stably connected to the predetermined position.

[0048] The first cover plate 40 is used to cover the transmission assembly 32 and the limiting part 33, and the second cover plate 50 is used to cover the limiting structure 11. It has a dustproof function, reduces dust and foreign objects from entering the adjustment assembly 30, and can also prevent jamming when the shelf body 20 is adjusted.

[0049] The door shelf adjustment structure in the above embodiment includes a door 10, a shelf body 20, an adjustment component 30, a first cover plate 40, and a second cover plate 50. The shelf body 20 is slidably disposed on the door 10. The limiting part 33 of the adjustment component 30 cooperates with the limiting structure 11 on the door 10 and can be used to adjust the position of the shelf body 20 on the door 10. The first cover plate 40 can cover the transmission component 32 and the limiting part 33 of the adjustment component 30, and the second cover plate 50 can cover the limiting structure 11 on the door 10. Therefore, the transmission component 32 and the limiting structure 11 can be hidden to prevent dirt and foreign objects from entering, and can also prevent the shelf body 20 from jamming when adjusting its position.

[0050] Please refer to some embodiments of this utility model. Figure 1 and Figure 2 The first direction Z is the vertical direction, meaning that the shelf body 20 can slide relative to the door 10 in the vertical direction to adjust its position. In this embodiment, the height of the shelf body 20 can be adjusted.

[0051] Please refer to some embodiments of this utility model. Figures 3 to 6 The adjusting component 30 is disposed at the end of the shelf body 20 in the second direction X, and the insertion end of the limiting part 33 faces the middle of the shelf body 20 in the second direction X. The limiting structure 11 is located in the middle of the door 10 in the second direction X. The first direction Z and the second direction X are perpendicular to each other. The second direction is the length direction of the shelf body 20 (the width direction of the door 10). The middle of the second direction is the middle of the door 10 in the width direction. Any part other than the end of the door 10 in the width direction can be understood as the middle of the door 10 in the width direction. Correspondingly, the insertion part of the limiting part 33 and the limiting structure 11 are both located in the middle of the door 10 in the second direction.

[0052] By setting the insertion end of the limiting part 33 toward the center of the shelf body 20 in the second direction, and setting the limiting structure 11 at the center of the door 10 in the second direction, the limiting structure 11 and the limiting part 33 can be close to the center of the door 10 in the width direction, which facilitates the blocking of the limiting structure 11 and the limiting part 33.

[0053] Please refer to some embodiments of this utility model. Figures 3 to 6 There are two limiting structures 11 and two adjusting components 30, and they are arranged in a one-to-one correspondence. The second cover plate 50 is fixed to the limiting structure 11, and the limiting structure 11 is located inside the door 10 and between the second cover plate 50. Both adjusting components 30 are located at the ends of the shelf body 20 in the second direction, that is, the two adjusting components 30 are respectively located at both ends of the shelf body 20 in the second direction. The one-to-one correspondence between the limiting structure 11 and the adjusting component 30 means that the limiting part 33 of one adjusting component 30 is inserted into one of the limiting structures 11. The second cover plate 50 is fixed to the limiting structure 11 and simultaneously covers the limiting structure 11.

[0054] By setting two limiting structures 11 and two adjusting components 30, the shelf body 20 can slide more smoothly in the first direction and is also more stable in the locked state. Meanwhile, the limiting parts 33 of the two adjusting components 30 are both located in the middle of the door 10 in the second direction, and the two limiting structures 11 are both located in the middle of the door 10 in the second direction. Therefore, the distance between the two limiting structures 11 is relatively close, making the movement of the shelf body 20 smoother and less prone to jamming. Furthermore, it is more convenient to use the second cover plate 50 to cover the two limiting structures 11. In related technologies, the limiting structures 11 are all located at the ends of the shelf body 20 in the second direction, making it impossible for the limiting structures 11 to be covered. In this embodiment, the two limiting structures 11 are relatively close, allowing the second cover plate 50 to cover them.

[0055] In some embodiments, the limiting structure 11 and the second cover plate 50 are integrally formed, and the two components are integrally installed onto the door 10.

[0056] In some embodiments, the limiting structure 11 and the second cover plate 50 are formed separately, and the second cover plate 50 clamps and fixes the limiting structure 11 to the door 10.

[0057] Please refer to some embodiments of this utility model. Figure 3 and Figure 4 The shelf body 20 has a recessed structure 21 on the side facing the door 10 for the second cover plate 50 and the limiting structure 11 to be inserted. The inner wall of the recessed structure 21 extends toward the limiting structure 11 to form an extension 22. The second cover plate 50 is sandwiched between the extension 22 and the bottom wall of the recessed structure 21. The extension 22 has a clearance hole 221 for the limiting part 33 to extend out. The recessed structure 21 is a recess on the side of the shelf body 20 facing the door 10. The recessed structure 21 cooperates with the second cover plate 50 and the limiting structure 11 to allow the shelf body 20 to slide along the first direction of the door 10. The inner wall of the recessed structure 21 extends toward the limiting structure 11, which is equivalent to the inner wall of the recessed structure 21 extending along the second direction. The extension 22 formed after the extension is located inside the recessed structure 21. The opening side of the recessed structure 21 is the top of the recessed structure 21, and the side of the recessed structure 21 directly opposite its opening is the bottom wall of the recessed structure 21. When the handle 31 drives the limiting part 33 to move through the transmission component 32, the limiting part 33 moves away from the limiting structure 11 and retracts to the extension part 22 through the clearance hole 221. When the external force on the handle 31 disappears, the limiting part 33 extends out from the clearance hole 221 and engages with the limiting structure 11.

[0058] The groove structure 21 forms a sliding connection between the shelf body 20 and the door 10. The extension 22 limits the movement of the second cover 50 in the second direction and guides its movement in the first direction. Furthermore, the limiting part 33 extends from the clearance hole 221 of the extension 22, and at least a portion of the limiting part 33 is located within the extension 22, thus providing some protection for the limiting part 33.

[0059] In some embodiments, the extension 22 is a hollow structure, the shelf body 20 is lighter, and the clearance hole 221 is opened on the surface shell of the extension 22, making it easier for the limiting part 33 to slide relative to the extension 22 and less likely to get stuck.

[0060] Please refer to some embodiments of this utility model. Figure 3 and Figure 5The adjustment component 30 is located at the bottom of the shelf body 20. The bottom of the shelf body 20 is the side of the shelf body 20 facing the ground. Thus, the first cover plate 40 is also located at the bottom of the shelf body 20. When the user uses the refrigerator, because the adjustment component 30 and the first cover plate 40 are located at the bottom of the shelf body 20, they are in the user's blind spot, resulting in a more seamless appearance when the refrigerator door 10 is open.

[0061] Please refer to some embodiments of this utility model. Figure 5 and Figure 6 The transmission assembly 32 includes a first sliding rod 321, a second sliding rod 322, and an elastic element 323. The first sliding rod 321 is driven by the handle 31 to move in the third direction Y, and the second sliding rod 322 is driven by the first sliding rod 321 to move in the second direction X. One of the first sliding rod 321 and the second sliding rod 322 has a guide hole 3211, and the other has a guide portion 3221 located in the guide hole 3211. The length direction of the guide hole 3211 is set at an acute angle with both the second direction and the third direction. The limiting portion 33 is fixed to one end of the second sliding rod 322, and the elastic element 323 is used to provide a clamping force for the limiting portion 33 to be inserted into the limiting structure 11. The first direction Z, the second direction X, and the third direction Y are arranged perpendicularly to each other. Handle 31 drives the first sliding rod 321 to move in the third direction. Through the cooperation of guide hole 3211, the first sliding rod 321 drives the second sliding rod 322 to move in the second direction. The second sliding rod 322 drives the limiting part 33 to slide in the second direction, realizing the insertion and separation of the limiting part 33 and the limiting structure 11. When it is necessary to adjust the position of the shelf body 20, handle 31 drives the first sliding rod 321 to move in the third direction, and the second sliding rod 322 moves in the second direction. The elastic element 323 is compressed, the limiting part 33 disengages from the limiting structure 11, and then the shelf body 20 is slid to the predetermined position in the first direction. Handle 31 is released, and under the action of the rebound force of elastic element 323, the limiting part 33 is inserted into the limiting structure 11, so that the shelf body 20 is stably connected to the door 10.

[0062] The transmission assembly 32 includes a first sliding rod 321, a second sliding rod 322, and an elastic element 323. The first sliding rod 321 slides along a third direction, and the second sliding rod 322 slides along a second direction, allowing the limiting part 33 to be positioned at the center of the shelf body 20 in the second direction. Therefore, by configuring the transmission assembly 32, the positions of the limiting part 33 and the limiting structure 11 can be adjusted so that the limiting structure 11 is located at the center of the door 10 in the second direction, facilitating the concealment of the transmission assembly 32 and the limiting structure 11.

[0063] In some embodiments, the guide hole 3211 is elongated, and the length direction of the guide hole 3211 forms an angle of 45 degrees with both the second direction and the third direction, so that the movement of the first slide rod in the third direction is effectively converted into the movement of the second slide rod in the second direction.

[0064] In some embodiments, the bottom of the shelf body 20 has a first receiving groove 23 and a second receiving groove 24 that communicate with each other. The first receiving groove 23 extends along a third direction, and the second receiving groove 24 extends along a second direction. A first sliding rod 321 is located in the first receiving groove 23, and a second sliding rod 322 is located in the second receiving groove 24. A first support structure 26 is provided in the first receiving groove 23 to support the first sliding rod 321, allowing the first sliding rod 321 to move within the first receiving groove 23. A second support structure 27 is provided in the second receiving groove 24 to support the second sliding rod 322, allowing the second sliding rod 322 to move within the second receiving groove 24.

[0065] Optionally, the first cover plate 40 is disposed over the openings of the first receiving groove 23 and the second receiving groove 24.

[0066] Please refer to some embodiments of this utility model. Figure 5 and Figure 6 The shelf body 20 has a sliding hole 25 along a third direction. A handle 31 is slidably disposed along the sliding hole 25, and one end of the handle 31 passes through the sliding hole 25 and is fixedly connected to the first sliding rod 321. The sliding hole 25 being provided along a third direction can be understood as having its length direction in the third direction. Since the handle 31 is fixedly connected to the first sliding rod 321, the handle 31 and the first sliding rod 321 move synchronously along the third direction.

[0067] The sliding hole 25 guides the movement of the handle 31, ensuring stable movement of both the handle 31 and the first sliding rod 321 along a first direction. The wall of the sliding hole 25 provides support for the connection between the handle 31 and the first sliding rod 321.

[0068] In some embodiments, please refer to Figure 5 and Figure 6 The handle 31 is elongated and extends along the second direction, which makes it more comfortable for the user to pull the handle 31.

[0069] Please refer to some embodiments of this utility model. Figure 5 and Figure 6The shelf body 20 has a support plate 271 and a stop plate 28. The support plate 271 allows the second sliding rod 322 to pass through, and the stop plate 28 is used to stop and limit the portion 33. The two ends of the elastic member 323 abut against the support plate 271 and the limiting portion 33, respectively. The support plate 271 allows the second sliding rod 322 to pass through, and the support plate 271 has a corresponding notch or hole. The support plate 271 is at least a part of the aforementioned second support structure 27, and can support the second sliding rod 322. When the second sliding rod 322 slides along the second direction, the elastic member 323 is compressed or stretched. Specifically, in combination with... Figure 6 When the handle 31 moves in the third direction (upward), the second sliding rod 322 moves in the second direction (to the left), the elastic element 323 is compressed, and the limiting part 33 retracts from the limiting structure 11. When the handle 31 loses external force, the second sliding rod 322 rebounds under the action of the elastic element 323, and the limiting part 33 reconnects to the limiting structure 11.

[0070] The support plate 271 facilitates the installation of the elastic element 323, and the stop plate 28 is provided to stop the limiting part 33 and prevent the limiting part 33 from moving too far and damaging the limiting structure 11.

[0071] Please refer to some embodiments of this utility model. Figure 7 and Figure 8 The insertion end of the limiting part 33 is an insertion tooth, and the limiting structure 11 is a rack structure. When the insertion tooth and the rack structure are inserted into each other, the insertion is relatively stable, and the shelf body 20 is not easy to shake.

[0072] Optionally, the insertion teeth are ratchet teeth, and the rack structure is a ratchet.

[0073] This utility model also provides a refrigerator, which includes the door shelf adjustment structure of any of the above embodiments. The refrigerator also includes a cabinet, an inner liner, and other structures.

[0074] The refrigerator provided by this utility model adopts the above-mentioned door shelf adjustment structure. The door shelf adjustment structure includes a door 10, a shelf body 20, an adjustment component 30, a first cover plate 40, and a second cover plate 50. The shelf body 20 is slidably disposed on the door 10. The limiting part 33 of the adjustment component 30 cooperates with the limiting structure 11 on the door 10 and can be used to adjust the position of the shelf body 20 on the door 10. The first cover plate 40 can cover the transmission component 32 and the limiting part 33 of the adjustment component 30, and the second cover plate 50 can cover the limiting structure 11 on the door 10. Therefore, the transmission component 32 and the limiting structure 11 can be hidden to prevent dirt and foreign objects from entering, and can also prevent the shelf body 20 from jamming when adjusting its position.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
