[0002] Currently, refrigerators sold on the market typically have a fixed door height at the factory to accommodate standard installation environments. However, in actual use, due to uneven ground, installation position deviations, or other reasons, the refrigerator door height may become mismatched, resulting in the door not closing completely or not closing properly, affecting the refrigerator's performance and lifespan. Traditional hinge devices usually only allow for height adjustment. This single adjustment function is inadequate when facing multi-dimensional installation problems and cannot meet users' needs for multi-directional adjustment of the refrigerator door position. For example, during actual installation, situations may arise such as tilted walls, uneven ground, or irregular door frame structures, all of which require multi-directional adjustment of the refrigerator door position. However, traditional hinge devices lack multi-directional adjustment capabilities and cannot simultaneously achieve adjustments in multiple directions such as up / down and left / right, causing the refrigerator door to be unable to open and close properly, or even unable to close completely, seriously affecting the refrigerator's sealing performance and cooling efficiency.

[0035] To make the technical problems, technical solutions, and 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.

[0036] Currently, refrigerators sold on the market typically have a fixed door height at the factory to accommodate standard installation environments. However, in actual use, due to uneven ground, installation position deviations, or other reasons, refrigerator doors may experience height mismatches, resulting in doors that cannot close completely or not close properly, affecting the refrigerator's performance and lifespan. Therefore, how to achieve convenient multi-directional adjustment of the refrigerator door has become a pressing technical problem. Specifically, existing technologies have the following main problems: 1) Single adjustment direction: Traditional hinge devices usually only allow adjustment in one direction, mostly only up and down. This single adjustment function is inadequate when facing multi-dimensional installation problems and cannot meet users' needs for multi-directional adjustment of the refrigerator door position. For example, during actual installation, situations such as tilted walls, uneven ground, or irregular door frame structures may be encountered, all of which require multi-directional adjustment of the refrigerator door position. However, traditional hinge devices lack multi-directional adjustment capabilities and cannot simultaneously achieve adjustments in multiple directions such as up and down and left and right, resulting in the refrigerator door being unable to open and close normally, or even unable to close completely, seriously affecting the refrigerator's sealing performance and cooling efficiency. 2) Poor Installation Adaptability: In actual installation, especially in older buildings or locations with complex interior design, walls may be slightly tilted, and floors may be uneven. Traditional hinge systems, lacking multi-directional adjustment capabilities, struggle to adapt to these challenging environments, leading to difficulty opening and closing the refrigerator door, or even malfunction. For example, on uneven ground, the refrigerator body may tilt, and traditional hinge systems cannot compensate for this tilt, causing the door to fail to close completely, reducing sealing performance, and consequently affecting cooling efficiency and energy conservation. This poor installation adaptability not only impacts the user experience but can also lead to decreased refrigerator performance and increased energy consumption.

[0037] To address these issues, designs for adjusting refrigerator doors have emerged in the market. However, most of these designs suffer from the following shortcomings: For example, patent document CN211598171U discloses a door height adjustment device and refrigerator that uses a single-axis rotation for vertical height adjustment. However, this design suffers from several problems: firstly, the single-axis design lacks sufficient support; secondly, it can only adjust vertically, not horizontally. Patent document CN108731359A discloses a refrigerator door height adjustment device and refrigerator that uses a cam in conjunction with a rotating shaft, with the cam rotating to adjust the vertical height. However, this design suffers from several problems: firstly, the cam experiences significant wear and has a short lifespan; secondly, the angle of the wrench is not ergonomically sound.

[0038] In view of this, this utility model proposes a hinge device and a refrigerator with adjustable function. The hinge device adopts a multi-dimensional adjustment design, which can adapt to complex installation environments. Each adjustment mechanism adopts a modular design, which facilitates assembly and maintenance, while improving the flexibility and accuracy of adjustment.

[0039] Please refer to the following: Figures 1 to 7 The hinge device with adjustment function proposed in this utility model includes a hinge plate 1, a lateral adjustment component 2, and a longitudinal adjustment component 3. The hinge plate 1 is rotatably connected to the refrigerator door via a hinge shaft 10; the lateral adjustment component 2 is fixed to the refrigerator body and connected to the hinge plate 1, used to realize the lateral movement of the refrigerator door; the longitudinal adjustment component 3 is connected between the hinge plate 1 and the refrigerator door, used to realize the longitudinal movement of the refrigerator door.

[0040] This invention combines the horizontal adjustment component 2 and the vertical adjustment component 3, employing a multi-dimensional adjustment design to achieve multi-dimensional adjustment functions in both vertical and horizontal directions, adapting to complex installation environments. The horizontal adjustment component 2 and the vertical adjustment component 3 operate independently in the adjustment direction without interfering with each other. Each adjustment mechanism adopts a modular design, which not only facilitates assembly and maintenance but also improves the flexibility and accuracy of adjustment.

[0041] like Figure 4 , Figure 5 , Figure 6 As shown, the horizontal adjustment component 2 includes a fixed slide rail 21 and a horizontal movement limiting component 22; the fixed slide rail 21 is fixedly connected to the refrigerator body by fasteners, and a horizontal sliding groove 23 is formed inside the fixed slide rail 21, and a hinge plate 1 is slidably disposed in the horizontal sliding groove 23; the horizontal movement limiting component 22 can be movably inserted into the horizontal sliding groove 23 and connected to the hinge plate 1.

[0042] In the hinge device proposed in this utility model, the lateral adjustment component 2 mainly consists of a fixed slide rail 21 and a lateral movement limiting member 22. Users can adjust the lateral movement limiting member 22 to move it to a position separated from the hinge plate 1, thereby achieving sliding adjustment of the hinge plate 1 and the refrigerator door in the left-right direction, ensuring precise alignment of the refrigerator door in the left-right position. After adjustment, the lateral movement limiting member 22 is moved back to the state connected to the hinge plate 1 to effectively limit the refrigerator door. This design does not affect the vertical adjustment, ensuring that the adjustment directions do not interfere with each other. Furthermore, the design of the lateral adjustment component 2 in this utility model fully considers the convenience of installation and use. The adjustment process does not require professional tools; users only need to rotate the lateral movement limiting member 22 and slide the hinge plate 1 to easily complete the lateral adjustment, making the operation simple and easy.

[0043] like Figure 6As shown, the fixed slide rail 21 is formed by a fixed bottom wall and a U-shaped side wall together to form a transverse sliding groove 23; the fixed bottom wall has multiple fixing holes for fasteners to pass through, and the middle section of the U-shaped side wall has a positioning hole for the transverse movement limiting member 22 to pass through. The number of fixing holes can be flexibly set according to actual needs, and is preferably configured as three fixing holes.

[0044] In the hinge device proposed in this utility model, the fixed slide rail 21 is formed by a fixed bottom wall and a U-shaped side wall together to create a transverse sliding groove 23. This ensures smooth movement of the hinge plate 1 within the transverse sliding groove 23 and effectively prevents the hinge plate 1 from falling off. Simultaneously, the fixing holes allow fasteners to firmly fix the fixed slide rail 21 to the refrigerator body, while the positioning holes allow the transverse limiting member 22 to pass through and connect to the hinge plate 1, thereby effectively limiting the movement of the hinge plate 1 and the refrigerator door. This design not only ensures the reliability and durability of the hinge device but also simplifies user operation and improves the user experience.

[0045] like Figure 6 As shown, the abutting end of the transverse limiting member 22 is connected to the hinge plate 1 by a thread. The transverse limiting member 22 is preferably a transverse screw. This threaded connection method is not only stable and reliable, but also convenient to operate and easy for users to adjust. During transverse adjustment, the user only needs to rotate the transverse limiting member 22 to change its position in the transverse sliding groove, thereby realizing the limiting and releasing functions of the hinge plate 1.

[0046] like Figure 7 As shown, the hinge plate 1 includes a sliding support portion 11 and a cantilever support portion 12; the sliding support portion 11 is slidably connected to the transverse sliding groove 23, and the cantilever support portion 12 protrudes from the transverse sliding groove 23 and is fixedly provided with a hinge shaft 10.

[0047] In the hinge device proposed in this utility model, the hinge plate 1 includes a sliding support portion 11 and a cantilever support portion 12. The design of the sliding support portion 11 allows it to move smoothly in the horizontal sliding groove 23, thereby allowing the user to slide and adjust the refrigerator door in the left and right directions. The cantilever support portion 12 protrudes from the horizontal sliding groove 23 and is fixedly equipped with a hinge shaft 10 and a vertical adjustment component 3, so that the user can make fine adjustments to the refrigerator door in the up and down directions to ensure precise alignment of the door height. This hinge plate 1 structure effectively realizes the separate installation of the horizontal adjustment component 2 and the vertical adjustment component 3, ensuring that the adjustment directions do not interfere with each other, allowing the user to easily complete multi-dimensional adjustment operations. In addition, the sliding support portion 11, the cantilever support portion 12, and the hinge shaft 10 are all made of high-strength materials, effectively improving the support stability.

[0048] like Figure 2 , Figure 5 , Figure 6As shown, the longitudinal adjustment assembly 3 includes an actuating component, a transmission component, and a longitudinal moving platform 36. The actuating component includes an actuating gear 31 rotatably mounted on the hinge plate 1. The transmission component includes a bearing 32 sleeved on the hinge shaft 10, a central gear 33 sleeved on the bearing 32 and meshing with the actuating gear 31, and a transmission gear 34 rotatably mounted on the hinge plate 1 and meshing with the central gear 33. The transmission gear 34 is rotatably connected to the longitudinal moving platform 36 via a gear transmission screw 35. The longitudinal moving platform 36 is sleeved on the hinge shaft 10 and connected to the refrigerator door.

[0049] In the hinge device proposed in this utility model, the longitudinal adjustment component 3 mainly consists of a toggle component, a transmission component, and a longitudinal moving platform 36. The user can adjust the toggle component, which in turn drives the longitudinal moving platform 36 to rise and fall via the transmission component, thereby achieving fine-tuning of the refrigerator door in the vertical direction and ensuring precise alignment of the refrigerator door height. Furthermore, the longitudinal adjustment component 3 incorporates a high-precision lead screw and nut pair design, ensuring accurate adjustment. The user can rotate the toggle gear 31, which in turn drives the gear transmission screw 35 to rotate via the central gear 33 and the transmission gear 34, achieving millimeter-level fine-tuning of the longitudinal moving platform 36, thereby ensuring a tight fit of the refrigerator door when closed, improving sealing performance and cooling efficiency.

[0050] like Figure 6 As shown, the actuating gear 31 includes a first actuating gear 311 and a second actuating gear 312, and the second actuating gear 312 meshes with the first actuating gear 311 and the center gear 33 respectively.

[0051] The hinge device proposed in this utility model includes a first actuating gear 311 and a second actuating gear 312 that mesh with each other. Even after the user slides the refrigerator door left or right, although the vertical adjustment component 3 is relatively concealed, the user can still indirectly drive the second actuating gear 312 by operating the first actuating gear 311, which is located on the outer side, thereby achieving precise fine-tuning of the refrigerator door height. The ingenious cooperation between the first actuating gear 311 and the second actuating gear 312 not only significantly improves the convenience of operation but also ensures the accuracy and stability of adjustment, making the design of the entire hinge device more user-friendly and fully meeting the diverse needs of users for refrigerator door adjustment.

[0052] like Figure 6As shown, the transmission gear 34 includes a first transmission gear 341, a second transmission gear 342, and a third transmission gear 343. The first transmission gear 341, the second transmission gear 342, and the third transmission gear 343 mesh with the center gear 33 respectively. The first transmission gear 341 is rotatably connected to the longitudinal moving platform 36 through a first gear transmission screw 351. The second transmission gear 342 is rotatably connected to the longitudinal moving platform 36 through a second gear transmission screw 352. The third transmission gear 343 is rotatably connected to the longitudinal moving platform 36 through a third gear transmission screw 353.

[0053] In the hinge device proposed in this utility model, three gear-driven screws 35 support the longitudinally moving platform 36 and synchronously drive its lifting and lowering, ensuring that it will not loosen or deform during adjustment. Even under frequent adjustment operations, the hinge device can still maintain stable support performance.

[0054] This utility model also proposes a refrigerator, including a cabinet, a door, and a hinge device with adjustment function.

[0055] The hinge device proposed in this invention, through the combination of the lateral adjustment component 2 and the longitudinal adjustment component 3, adopts a multi-dimensional adjustment design, realizing multi-dimensional adjustment functions in both vertical and horizontal directions, thus adapting to complex installation environments. The lateral adjustment component 2 and the longitudinal adjustment component 3 operate independently in the adjustment direction without interfering with each other. Furthermore, each adjustment mechanism adopts a modular design, which not only facilitates assembly and maintenance but also significantly improves the flexibility and precision of adjustment. This multi-dimensional adjustment function not only meets the diverse needs of users in different installation environments but also greatly improves the adaptability and installation flexibility of the refrigerator.

[0056] In addition, the refrigerator includes multiple doors and multiple adjustable hinge devices corresponding to each door. Each hinge device is located at the bottom of each door and can be independently adjusted up and down as well as left and right to adapt to the specific needs of different doors in different installation positions. This flexible and versatile adjustment method further enhances the overall aesthetics and practicality of the refrigerator.

[0057] To facilitate a clearer understanding, the hinge device proposed in this utility model will be described in detail below with reference to the accompanying drawings.

[0058] like Figure 2 , Figure 5 , Figure 6As shown, the hinge device includes a hinge plate 1, a lateral adjustment assembly 2, and a longitudinal adjustment assembly 3. A hinge shaft 10 is mounted on the hinge plate 1. The lateral adjustment assembly 2 includes a fixed slide rail 21 with an internal lateral sliding groove 23, and a lateral movement limiting member 22. The longitudinal adjustment assembly 3 includes a first actuating gear 311, a first gear fixing screw 313, a second actuating gear 312, a second gear fixing screw 314, a bearing 32, a center gear 33, a first transmission gear 341, a second transmission gear 342, a third transmission gear 343, a first gear transmission screw 351, a second gear transmission screw 352, a third gear transmission screw 353, and a longitudinal moving platform 36.

[0059] The installation process of the hinge device is as follows: The fixed slide rail 21 is securely installed on the front beam of the housing using screws, and then the hinge plate 1 is smoothly slid into the transverse sliding groove 23. Next, the transverse limiting member 22 is screwed into the transverse sliding groove 23 and tightly connected to the hinge plate 1. Then, the longitudinal adjustment assembly 3 is installed. First, the bearing 32 is fitted onto the hinge shaft 10, and then the central gear 33 is fitted onto the bearing 32, forming a central transmission structure. Then, the first actuating gear 311 is installed in the outermost hole of the hinge plate 1 via the first gear fixing screw 313, and the second actuating gear 312 is installed via the second gear fixing screw 314. Next, the first transmission gear 341 is installed in the other three holes of the hinge plate 1 via the first gear transmission screw 351, the second transmission gear 342 via the second gear transmission screw 352, and the third transmission gear 343 via the third gear transmission screw 353. Finally, the longitudinal moving platform 36 is fixed to the lifting slider on the three gear drive screws 35, or the longitudinal moving platform 36 is directly connected to the three gear drive screws 35 by threads.

[0060] The hinge mechanism operates as follows: First, the first actuating gear 311 is activated, indirectly driving the second actuating gear 312. Then, power is transmitted to the three transmission gears 34 via the central gear 33. When these three transmission gears 34 drive the three gear transmission screws 35 to rotate, the longitudinal moving platform 36 rises and falls accordingly, thus achieving longitudinal movement. Furthermore, by loosening the lateral movement limiter 22, moving the refrigerator door, and then re-fixing the lateral movement limiter 22, lateral movement can be achieved.

[0061] The hinge device and refrigerator proposed in this utility model have the following significant advantages:

[0062] 1) Multi-dimensional adjustment function: With a vertical adjustment component, users can easily adjust the height of the refrigerator door to adapt to different installation environments; with a horizontal adjustment component, users can slide the door horizontally to ensure precise alignment of the refrigerator door in the left and right positions. This multi-dimensional adjustment function not only meets the needs of users in different installation environments, but also significantly improves the adaptability and installation flexibility of the refrigerator.

[0063] 2) Independent adjustment mechanism design: In order to ensure the independence and non-interference of each adjustment direction, this utility model adopts a modular independent adjustment mechanism design. This independent adjustment mechanism design not only improves the accuracy of adjustment, but also ensures that there is no interference between each adjustment direction, so that users can easily complete multi-dimensional adjustment.

[0064] 3) Precise Adjustment and Support: The longitudinal adjustment mechanism of this invention adopts a high-precision lead screw and nut pair design to ensure precise adjustment. Gear transmission drives the screw to rotate, achieving the raising and lowering of the longitudinal moving platform and millimeter-level precision micro-adjustment. This ensures the tightness of the refrigerator door when closed, improving sealing performance and cooling efficiency. Furthermore, the hinge device's structural design significantly enhances support stability. Both the hinge plate and hinge shaft are made of high-strength materials, and a three-axis linkage optimized structural design ensures no loosening or deformation occurs during adjustment. Even under frequent adjustment operations, the hinge device maintains stable support performance.

[0065] 4) Ease of Installation and Use: The hinge device of this utility model is designed with ease of installation and use in mind. No professional tools are required for adjustment; users can easily complete multi-dimensional adjustments simply by rotating the gears, screws, or sliding the slider. Wide Adjustment Range: The adjustment range of each component is designed to fully meet the needs of the actual installation environment, ensuring adjustment even within a large deviation range to adapt to various wall structures and floor conditions.

[0066] 5) Energy saving and environmental protection: By improving the sealing performance of the refrigerator door, this utility model helps to improve the refrigeration efficiency of the refrigerator and reduce energy consumption, thereby achieving the purpose of energy saving and environmental protection.

[0067] 6) Long-term maintenance and upgrades: The modular design of this utility model not only facilitates installation and adjustment, but also makes future maintenance and upgrades convenient. Users can replace or upgrade some components as needed, extending the product's service life.
