[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] This application provides a shelf assembly and a cooling device. The shelf assembly allows for flexible adjustment of the height and depth of the shelves to improve the user experience. The following is a detailed description with reference to the accompanying drawings.

[0038] Please see Figure 1 as well as Figure 2 , Figure 1 This is a schematic diagram of a first structure of the shelf assembly provided in an embodiment of this application. Figure 2 for Figure 1 An explosion diagram.

[0039] This application provides a shelf assembly 10 that can be installed inside a refrigeration device, such as a refrigerator, to divide storage space.

[0040] The shelf assembly 10 includes a shelf 11, a first shelf fixing seat 12, a second shelf fixing seat 13, a first cabinet fixing seat 14, a second cabinet fixing seat 15, and a connecting rod 16. The shelf 11 is the main load-bearing surface of the shelf assembly 10, used for placing food, beverages, and other items. The shelf fixing seats (first shelf fixing seat 12 and second shelf fixing seat 13) support and fix the shelf 11, and are also key components for adjusting the height and depth of the shelf 11. The cabinet fixing seats (first cabinet fixing seat 14 and second cabinet fixing seat 15) can be installed on the cabinet of the refrigeration equipment, serving as the connection point between the shelf assembly 10 and the cabinet of the refrigeration equipment. The connecting rod 16 connects the second shelf fixing seat 13 and the second cabinet fixing seat 15. When the shelf 11 moves, the connecting rod 16 rotates relative to it, ensuring the stability and flexibility of the shelf assembly 10.

[0041] The first shelf fixing seat 12 and the second shelf fixing seat 13 are spaced apart and connected to the shelf 11 respectively. The first box fixing seat 14 is provided with a sliding groove 141, and at least a part of the structure of the first shelf fixing seat 12 can slide in the sliding groove 141. The two ends of the connecting rod 16 are connected to the second shelf fixing seat 13 and the second box fixing seat 15 respectively.

[0042] When the shelf 11 is lowered and moves toward the first horizontal direction, or when the shelf 11 is raised and moves toward the second horizontal direction, the first shelf fixing seat 12 slides in the slide groove 141 of the first box fixing seat 14, and the connecting rod 16 rotates relative to the second shelf fixing seat 13 and the second box fixing seat 15, with the first horizontal direction being opposite to the second horizontal direction.

[0043] Understandably, the shelf 11 has two positional states: initial position and target position.

[0044] The initial position refers to the shelf 11 being located at a relatively high and deep position within the refrigeration unit. This design primarily aims to maximize the use of the internal space of the refrigeration unit when items on the shelf 11 do not need to be frequently accessed. At this point, the shelf 11 is stably positioned at a high level, saving space and maintaining a tidy internal environment.

[0045] The target position refers to the shelf 11 having moved towards the user, being closer and lower than the user. This design is mainly to make it easier for the user to easily retrieve the required items. When the user needs to take out or put in an item, with a simple operation, the shelf 11 can smoothly move along the preset trajectory to a more convenient height and position, greatly reducing the difficulty and inconvenience of retrieving items.

[0046] When shelf 11 moves from its initial position to its target position, it lowers and moves towards a first horizontal direction; when it moves from the target position back to its initial position, it raises and moves towards a second horizontal direction. Through the cooperation of the slide rail 141 and the connecting rod 16, it is ensured that shelf 11 remains horizontal throughout its movement, meaning the plane of shelf 11 is parallel to either the first or second horizontal direction, facilitating the stability of items placed on it. Users can easily lower shelf 11 to a more convenient position for retrieving items, or raise its height as needed to accommodate storage needs for items of different sizes. This design not only improves the utilization of storage space but also greatly enhances ease of use.

[0047] Please see Figure 3 as well as Figure 4 , Figure 3 This is a structural schematic diagram of the first housing fixing base provided in an embodiment of this application. Figure 4 This is a schematic diagram of the structure of the first shelf fixing base provided in an embodiment of this application. In some embodiments, the slide 141 includes a first groove segment 1411 and a second groove segment 1412, the first groove segment 1411 and the second groove segment 1412 are connected; the opening of the first groove segment 1411 is flush with the opening of the second groove segment 1412, and the groove depth of the first groove segment 1411 is greater than the groove depth of the second groove segment 1412. The first shelf fixing base 12 includes a first fixing part 121 and a positioning pin 122, the positioning pin 122 is connected to the first fixing part 121, the first fixing part 121 is connected to the shelf 11, and the positioning pin 122 can be engaged in the first groove segment 1411 so that the shelf 11 stays in the initial position.

[0048] When a user needs to move shelf 11 from its initial position to its target position, the user must first pull the positioning pin 122 along the axis of the first groove segment 1411 and slide the positioning pin 122 within the second groove segment 1412. Under the influence of gravity and the pulling force provided by the user, shelf 11 can move from its initial position to its target position. When shelf 11 reaches its target position, the positioning pin 122 abuts against the groove wall of the second groove segment 1412, effectively preventing further sliding of shelf 11 and ensuring that shelf 11 remains stably in the target position, thereby greatly facilitating the user's access to items.

[0049] When a user needs to move shelf 11 from a target position to its initial position, in some cases, the user needs to lift shelf 11 so that the positioning pin 122 moves in the reverse direction along the second groove segment 1412 to the first groove segment 1411 and re-engages, which is an intuitive and effective operating method. In other cases, the user can release shelf 11, and using the spring mechanism or gravity self-balancing principle that may be contained in the slide 141 or the connecting rod 16, shelf 11 can automatically and smoothly return to its initial position.

[0050] The first fixing part 121 includes a first clamping part and a first connecting part. It tightly clamps the first and second surfaces of the shelf 11 along its thickness direction. This clamping method not only ensures that the shelf 11 is securely installed in the predetermined position, but also improves the overall load-bearing capacity by distributing pressure, allowing the shelf 11 to remain stable and undisturbed even when carrying heavy loads. Furthermore, the first clamping part is typically made of high-strength, corrosion-resistant material to withstand wear and tear during long-term use and the effects of the external environment, further extending its service life. The first connecting part extends from the first clamping part along the thickness direction of the shelf 11, enhancing the connection strength between the first fixing part 121 and the shelf 11, and providing a reliable support point for the installation of subsequent components. The positioning pin 122 connects to the first connecting member. The length direction of the positioning pin 122 is parallel to the plane of the shelf 11. During the movement of the shelf 11 along the slide groove 141, the positioning pin 122 effectively prevents the shelf 11 from tilting or deviating from the predetermined path due to external forces or improper operation. The positioning pin 122 ensures that the plane of the shelf 11 is always parallel to the groove depth direction of the slide 141, and can maintain good operation even when moving quickly or encountering slight vibration, thereby protecting the shelf 11 and the items it carries, and also improving the operating efficiency and reliability of the entire system.

[0051] Please see Figure 5 as well as Figure 6 , Figure 5 This is a schematic diagram of a second structure of the shelf assembly provided in an embodiment of this application. Figure 6 This is a partial structural schematic diagram of the shelf assembly provided in an embodiment of this application. The connecting rod 16 is a mechanical part, typically used to connect two or more components, enabling them to move relative to each other or transmit forces. In this embodiment, the connecting rod 16 connects the second shelf fixing seat 13 and the second housing fixing seat 15, serving to support and stabilize the structure.

[0052] There are multiple connecting rods 16. Multiple connecting rods 16 can more effectively distribute the load, preventing structural damage caused by excessive stress at a single point. Furthermore, multiple connecting rods 16 can increase system redundancy; even if one connecting rod 16 fails, the others can continue to function, ensuring the stability and safety of the overall structure. Each connecting rod 16 is connected to the second shelf fixing seat 13 and the second housing fixing seat 15, respectively. This connection method ensures a secure connection between the second shelf fixing seat 13 and the second housing fixing seat 15. As a connecting component, the connecting rod 16 can achieve a tight fit with the shelf fixing seat and the housing fixing seat, thereby providing stable support and positioning functions.

[0053] The multiple links 16 may include a first link 161 and a second link 162. The first link 161 and the second link 162 are parallel to each other and have the same length, which can ensure that they are subjected to uniform force during operation and avoid skewing or twisting due to differences in length.

[0054] The second shelf fixing base 13 includes a second fixing part 131, a first rotating shaft 132, and a second rotating shaft 133. The second fixing part 131 has a first side and a second side in a direction parallel to the plane of the shelf 11. The first rotating shaft 132 is disposed on the first side of the second fixing part 131 and is connected to the first connecting rod 161. The second rotating shaft 133 is disposed on the second side of the second fixing part 131 and is connected to the second connecting rod 162.

[0055] Correspondingly, the second housing fixing base 15 includes a third fixing part 151, a third rotating shaft 152, and a fourth rotating shaft 153. The third fixing part 151 has a third side and a fourth side in a direction parallel to the plane where the shelf 11 is located. The third rotating shaft 152 is disposed on the third side of the third fixing part 151 and is connected to the first connecting rod 161. The fourth rotating shaft 153 is disposed on the second side of the third fixing part 151 and is connected to the second connecting rod 162.

[0056] By rationally setting the number and position of the rotation axes, it can be ensured that the load is evenly distributed under stress and the occurrence of stress concentration can be reduced. This not only improves the stability and load-bearing capacity of the structure, but also makes the overall structure more compact and aesthetically pleasing. At the same time, this design also helps to reduce manufacturing costs and improve production efficiency.

[0057] The axial direction of the first rotating shaft 132 is parallel to the axial direction of the second rotating shaft 133. When the first connecting rod 161 and the second connecting rod 162 rotate around the first rotating shaft 132 and the second rotating shaft 133 respectively, their motion trajectories are synchronized and coordinated. In mechanical structures, synchronization and coordination are crucial for ensuring the stability and performance of the overall structure. By maintaining the parallel relationship of the rotating shaft axes, the additional stress and friction caused by asynchronous movement of the connecting rod 16 can be minimized, thereby extending the service life of the structure and improving reliability. Correspondingly, the lines connecting the first rotating shaft 132 and the second rotating shaft 133, and the lines connecting the third rotating shaft 152 and the fourth rotating shaft 153, can be parallel and equal to achieve a similar four-bar linkage effect with the first connecting rod 161 and the second connecting rod 162, ensuring the synchronization and coordination of the connecting rod 16 during movement. In a four-bar linkage, the relative positions and angles of each link 16 are interrelated. By precisely designing the connection relationship of the rotation axes, the links 16 can maintain a stable geometric relationship during movement, thereby achieving the expected motion trajectory and mechanical performance.

[0058] The axes of the first rotation axis 132 and / or the second rotation axis 133 are parallel to the plane of the shelf 11, which helps to enhance the stability of the structure, especially under load. When the axes of the first rotation axis 132 and the second rotation axis 133 are parallel to the plane of the shelf 11, the first rotation axis 132 and the second rotation axis 133 can better support and distribute the load from the shelf 11, preventing the structure from deforming or tilting due to uneven stress. This design not only improves the load-bearing capacity of the structure, but also ensures the horizontal stability of the shelf 11, so that items placed on the shelf 11 can remain balanced and stable.

[0059] The curvature of the motion trajectory of the end of the connecting rod 16 connected to the second shelf fixing seat 13 is a first curvature, and the curvature of the slide 141 is a second curvature. The first curvature equals the second curvature, ensuring that the connecting rod 16 can smoothly transition along the curvature of the slide 141 during movement, avoiding jamming, impact, or vibration caused by curvature mismatch. By maintaining the equality of curvature, the continuity and smoothness of the movement of the connecting rod 16 can be ensured, thereby improving the overall structural efficiency and reliability. The motion trajectory of the end of the connecting rod 16 connected to the second shelf fixing seat 13 is parallel to the slide 141, which not only enhances the stability of the structure but also provides better guidance. When the connecting rod 16 moves along the slide 141, the parallel relationship ensures that the connecting rod 16 can always maintain correct alignment with the slide 141, thereby avoiding additional stress and friction caused by offset or tilt. This not only improves the load-bearing capacity and durability of the structure but also ensures the accuracy and controllability of the connecting rod 16 during movement.

[0060] Please see Figure 7 , Figure 7 This is a schematic diagram of a third structure of the shelf assembly provided in an embodiment of this application. The shelf 11 includes adjacent first corner portions 111 and second corner portions 112. The first shelf fixing seat 12 is connected to the first corner portion 111, and the second shelf fixing seat 13 is connected to the second corner portion 112. The first corner portion 111 and the second corner portion 112 are usually areas on the shelf 11 where the stress is concentrated. By tightly connecting them with the shelf fixing seats, it can be ensured that the shelf 11 remains stable and firm when bearing a load, preventing deformation or damage caused by uneven stress.

[0061] The shelf 11 can be plate-shaped, with a rectangular support surface. A rectangular support surface maximizes space utilization, accommodating more items while maintaining neatness and order. The plate-like structure provides sufficient strength and rigidity, ensuring the shelf 11 is not easily bent or deformed when bearing heavy loads. The first shelf fixing seat 12 and the second shelf fixing seat 13 can be located on the same side of the shelf 11, while the side opposite to this side is not connected to the first shelf fixing seat 12 or the second shelf fixing seat 13. This allows the positioning pin 122 to be removed from the first groove section 1411, thereby allowing the positioning pin 122 to slide in the second groove section 1412, thus changing the height and depth of the shelf 11.

[0062] Please see Figure 8 , Figure 8 This is a schematic diagram of a first structure of a refrigeration device provided in an embodiment of this application.

[0063] This application provides a refrigeration device 100, which is a device used to reduce, maintain or regulate the temperature in a specific space. It is commonly found in home, commercial or industrial environments, such as refrigerators and freezers.

[0064] The refrigeration device 100 includes a housing 20, a door, and a shelf assembly 10. The housing 20 has a storage space 23 for storing items and maintaining them at a specific temperature. The door is rotatably connected to the housing 20 and is used to open or close the storage space 23 for easy access to items by the user. The shelf assembly 10 may be the same as in the above embodiment, used to provide an additional storage layer within the storage space 23 of the refrigeration device 100, increasing storage efficiency.

[0065] Please see Figure 9 as well as Figure 10 , Figure 9 This is a schematic diagram of a second structure of the refrigeration equipment provided in an embodiment of this application. Figure 10 for Figure 9Cross-sectional view at AA. Shelf 11 is disposed within the receiving space 23. First box fixing seat 14 and second box fixing seat 15 are respectively connected to box 20, which are used to fix shelf assembly 10 on box 20 to ensure the stability and load-bearing capacity of shelf assembly 10.

[0066] The shelf 11 has two position states: initial position and target position.

[0067] The initial position refers to the shelf 11 being in a higher and deeper position in the accommodating space 23. This design is mainly to maximize the use of the internal space of the refrigeration unit 100 when it is not necessary to frequently take items off the shelf.

[0068] The target position refers to the shelf having moved towards the door, placing it closer and lower than the user. This design is primarily to facilitate easy access to desired items. When the user needs to retrieve or place items, a simple operation is all it takes for the shelf 11 to smoothly move along a preset trajectory to a more convenient height and position, greatly reducing the difficulty and inconvenience of retrieving items.

[0069] When the shelf moves from its initial position to its target position, it lowers and moves towards the door or the user (first horizontal direction); when it moves from the target position back to its initial position, it raises and moves away from the door or the user (second horizontal direction). The cooperation of the slide rail 141 and the connecting rod 16 ensures that the shelf 11 remains horizontal throughout its movement, facilitating the stability of items placed on it. Users can easily lower the shelf 11 to a more convenient position for retrieving items, or raise its height as needed to accommodate storage requirements for items of different sizes.

[0070] Please continue reading. Figure 8 The housing 20 includes a shell 21 and a liner 22, with the liner 22 housed within the shell 21, forming an accommodating space 23. The shell 21 is the external structure of the housing 20, typically made of robust and corrosion-resistant materials, used to protect the liner 22 and internal components, and to provide an aesthetically pleasing appearance. The liner 22 is the internal structure of the housing 20, typically made of insulating material, forming the accommodating space 23 to maintain a specific temperature environment. The housing 20 of the refrigeration equipment 100 adopts a composite structure design of shell 21 and liner 22. Shell 21, as the external protective layer, provides robust support and protection, effectively preventing external impacts and damage. Liner 22, as the internal insulation layer, uses highly efficient insulation materials and technologies to ensure a constant temperature and improved energy efficiency within the accommodating space 23. This composite structure design not only enhances the overall stability of the equipment but also improves its insulation performance and energy efficiency ratio.

[0071] Please see Figure 11 as well as Figure 12 , Figure 11 This is a schematic diagram of the box liner structure provided in an embodiment of this application. Figure 12 for Figure 11 A magnified schematic diagram of part B. The second box fixing seat 15 is inserted into the box liner 22 for fixation, improving the load-bearing capacity and stability of the shelf assembly 10; specifically, the box liner 22 is provided with fixing holes 223, and the second box fixing seat 15 is inserted into the fixing holes 223 of the box liner 22 for fixation. Further, a positioning protrusion 221 is provided on the side of the box liner 22 away from the receiving space 23, and correspondingly, a positioning groove is provided on the second box fixing seat 15; when the second box fixing seat 15 is fixed to the box liner 22, the positioning protrusion 221 is engaged in the positioning groove. Therefore, by using both insertion fixing and engagement fixing methods, the reliability of the second box fixing seat 15 being fixed to the box liner 22 can be increased.

[0072] Please continue reading. Figure 10 The first housing fixing seat 14 is disposed between the housing 21 and the inner box 22. The inner box 22 is provided with an elongated hole 222, which corresponds to the sliding groove 141. The first shelf fixing seat 12 passes through the elongated hole 222 and is slidably connected to the sliding groove 141. The elongated hole 222 on the inner box 22 can further limit the first shelf fixing seat 12 to improve the stability of the shelf 11 during movement.

[0073] The shelf assembly 10 and refrigeration device 100 provided in this application embodiment include a shelf 11, a first shelf fixing seat 12, a second shelf fixing seat 13, a first cabinet fixing seat 14, a second cabinet fixing seat 15, and a connecting rod 16. When the shelf 11 is lowered and moves towards a first horizontal direction, or when the shelf 11 is raised and moves towards a second horizontal direction, the first shelf fixing seat 12 slides within the sliding groove 141 of the first cabinet fixing seat 14, and the connecting rod 16 rotates relative to the second shelf fixing seat 13 and the second cabinet fixing seat 15, with the first horizontal direction opposite to the second horizontal direction. Through the design of the sliding guide rail and connecting rod 16 in the shelf assembly 10 provided in this application embodiment, users can easily lower the shelf 11 to a more convenient position for retrieving items, or raise the shelf 11 as needed to accommodate storage needs for items of different sizes. This design not only improves the utilization rate of storage space but also greatly enhances ease of use.
