[0008] The above technical solution has the following advantages or beneficial effects:

[0009] When it is necessary to use the folding shelf mechanism to place items to be refrigerated, the mounting plate can be rotated to directly in front of the first layer plate assembly, and the second layer plate assembly can be rotated to directly in front of the mounting plate. At this time, the rear end of the first layer plate assembly is stably lapped on the first support rib, and the first support rib provides a vertically upward supporting force for the first layer plate assembly. Moreover, the front end of the second layer plate assembly can be stably lapped on the second support rib, and the second support rib can provide a vertically upward supporting force for the second layer plate assembly. When a part of the heavy object is carried on the mounting plate, since the front end of the first layer plate assembly can abut against the rear end of the mounting plate and the front end of the mounting plate can abut against the rear end of the second layer plate assembly, it can prevent the front end of the first layer plate assembly and the rear end of the second layer plate assembly from folding downwards, so that the whole of the first layer plate assembly, the second layer plate assembly, and the mounting plate can support each other during the unfolding process, forming a strong first support tabletop, preventing the folding shelf mechanism from tipping over in the unfolded state, and being beneficial to still having good load-bearing capacity in the unfolded state of the folding shelf mechanism.

When not needed, the second layer plate assembly 32 can be folded or retracted to reduce the occupied space.

[0098] As Figure 5 shown, in some embodiments, the folding rack mechanism 3 may include a mounting plate 33. The mounting plate 33 may be movably disposed between the first layer plate assembly 31 and the second layer plate assembly 32.

[0099] In order to further improve the structural stability of the movable setting between the first layer plate assembly 31 and the second layer plate assembly 32, by providing a mounting plate 33 between the first layer plate assembly 31 and the second layer plate assembly 32, wherein, an additional support is provided between the first layer plate assembly 31 and the second layer plate assembly 32, and the mounting plate 33 can jointly form a more stable support structure with the first layer plate assembly 31 and the second layer plate assembly 32, thereby enhancing the stability and load-bearing capacity of the entire folding rack mechanism 3.

[0100] When the mounting plate 33 rotates to the front of the first layer plate assembly 31 and the second layer plate assembly 32 rotates to the front of the mounting plate 33, the rear end of the first layer plate assembly 31 can be supported on the first support rib 21, and the front end of the second layer plate assembly 32 can be supported on the second support rib 22, so that the front end of the first layer plate assembly 31 can abut against the rear end of the mounting plate 33, the front end of the mounting plate 33 can abut against the rear end of the second layer plate assembly 32, and the top surfaces of the first layer plate assembly 31, the second layer plate assembly 32 and the mounting plate 33 can be combined to form a first support tabletop 300 for supporting the articles to be refrigerated.

[0101] As Figure 5 shown, it should be noted that when the folding rack mechanism 3 is needed to place the articles to be refrigerated, the mounting plate 33 can be rotated to the front of the first layer plate assembly 31, and the second layer plate assembly 32 can be rotated to the front of the mounting plate 33. At this time, the rear end of the first layer plate assembly 31 is stably lapped on the first support rib 21, and the first support rib 21 provides a vertically upward supporting force for the first layer plate assembly 31. Moreover, the front end of the second layer plate assembly 32 can be stably lapped on the second support rib 22, and the second support rib 22 can provide a vertically upward supporting force for the second layer plate assembly 32. When the mounting plate 33 bears some heavy objects, since the front end of the first layer plate assembly 31 can abut against the rear end of the mounting plate 33, and the front end of the mounting plate 33 can abut against the rear end of the second layer plate assembly 32, it can prevent the front end of the first layer plate assembly 31 and the rear end of the second layer plate assembly 32 from folding downwards, so that the first layer plate assembly 31, the second layer plate assembly 32 and the whole mounting plate 33 can support each other during the unfolding process, forming a solid first support tabletop 300, which is beneficial to preventing the folding rack mechanism 3 from being overturned in the unfolded state, unable to carry objects and affecting the daily use performance of the folding rack mechanism 3.

[0102] As Figure 5 shown, in some embodiments, in the unfolded state of the folding rack mechanism 3, the top surface of the mounting plate 33, the top surface of the first layer plate assembly 31 and the top surface of the second layer plate assembly 32 can be located on the same horizontal plane, so that the first support tabletop 300 forms a continuous plane, which can better support the articles to be cooled.

[0103] As Figure 6 and Figure 7 shown, in some embodiments, a first stop portion 331 extending towards the first layer plate assembly 31 can be provided at the rear end of the mounting plate 33. When the mounting plate 33 rotates to the front of the first layer plate assembly 31, the first stop portion 331 can abut against the front end of the first layer plate assembly 31.

[0104] Among them, in order to prevent the structural instability at the rotational connection between the mounting plate 33 and the first layer plate assembly 31 and the second layer plate assembly 32 respectively, a first stop portion 331 is provided at the rear end of the mounting plate 33. When the mounting plate 33 rotates to the front of the first layer plate assembly 31, the first stop portion 331 can abut against the front end of the first layer plate assembly 31. The abutting portion between the first stop portion 331 and the first layer plate assembly 31 can form a support point, thereby preventing the front end of the first layer plate assembly 31 and the rear end of the mounting plate 33 from folding downwards, enhancing the stability of the rotational connection structure between the mounting plate 33 and the first layer plate assembly 31. On the other hand, it can also prevent excessive rotation between the mounting plate 33 and the first layer plate assembly 31, limit the rotation angle between the first layer plate assembly 31 and the mounting plate 33, so that the first layer plate assembly 31 cannot fold above the mounting plate 33.

[0105] As Figure 6 and Figure 7 shown, in some embodiments, the front end of the mounting plate 33 may be provided with a second stop portion 332 extending towards the second layer plate assembly 32; when the second layer plate assembly 32 rotates to the front of the mounting plate 33, the second stop portion 332 can abut against the rear end of the second layer plate assembly 32.

[0106] Among them, in order to prevent the structural instability at the rotational connection between the mounting plate 33 and the first layer plate assembly 31 and the second layer plate assembly 32 respectively, a second stop portion 332 is provided at the front end of the mounting plate 33. When the second layer plate assembly 32 rotates to the front of the mounting plate 33, the second stop portion 332 can abut against the rear end of the second layer plate assembly 32. The abutting portion between the second stop portion 332 and the second layer plate assembly 32 can form a support point, thereby preventing the rear end of the second layer plate assembly 32 and the front end of the mounting plate 33 from folding downwards, enhancing the stability of the rotational connection structure between the mounting plate 33 and the second layer plate assembly 32. On the other hand, it can also prevent excessive rotation between the mounting plate 33 and the second layer plate assembly 32, limit the rotation angle between the second layer plate assembly 32 and the mounting plate 33, so that the second layer plate assembly 32 cannot fold above the mounting plate 33.

[0107] In some embodiments, the first layer plate assembly 31 may include a first layer rack 311. The first layer rack 311 may have a planar structure, and the planar structure is used for placing items to be refrigerated.

[0108] As Figure 5As shown, in some embodiments, the first layer plate assembly 31 may include a first connecting member 312. The first connecting member 312 may be disposed at the front end of the first layer rack 311. The front end of the first connecting member 312 may be rotatably connected to the mounting plate 33. When the mounting plate 33 rotates to the front of the first layer plate assembly 31, the first stop portion 331 can abut against the front end of the first connecting member 312. By providing the first connecting member 312 at the front end of the first layer rack 311, the first connecting member 312 can drive the first layer rack 311 to rotate relative to the mounting plate 33. When the mounting plate 33 rotates to the front of the first layer plate assembly 31, since the first stop portion 331 abuts against the front end of the first connecting member 312, the first connecting member 312, the first layer rack 311, and the mounting plate 33 form a continuous support structure, making the first layer rack 311 more stable when supporting items and avoiding the problems of sinking or loosening at the front end of the first layer rack 311. Moreover, the rear end of the first layer rack 311 can be supported on the first support rib 21, so that the whole of the first layer rack 311 can be stably arranged in the refrigerating compartment 101.

[0109] In some embodiments, the first connecting member 312 may be provided with a first slot facing the first layer rack 311. The front end of the first layer rack 311 may be inserted into the first slot. By providing the first slot in the first connecting member 312 and inserting the front end of the first layer rack 311 into the first slot, the connection area and contact points between the first connecting member 312 and the first layer rack 311 can be increased. Moreover, the insertion fit between the two can effectively avoid the problems of loosening or displacement of the first layer rack 311 caused by vibration or impact during use, improving the stability and reliability of the first layer rack 311 assembly.

[0110] As Figure 5 shown, in some embodiments, the first slot may extend along the length direction of the front end of the first layer rack 311. Thus, the entire front end of the first layer rack 311 is wrapped and fixed, further increasing the connection area between the first connecting member 312 and the first layer rack 311.

[0111] As Figure 5 shown, in some embodiments, the second layer plate assembly 32 may include a second layer rack 321. The second layer rack 321 may have a planar structure for placing items to be refrigerated.

[0112] Figure 8 is Figure 5 a sectional view of; Figure 9 is Figure 8 a partial enlarged view of A in; Figure 10 is Figure 9 a schematic diagram of the first connecting member and the second connecting member in.

[0113] As Figure 8 andFigure 9 As shown, in some embodiments, the second layer plate assembly 32 may include a second connecting member 322 disposed at the rear end of the second layer rack 321. The rear end of the second connecting member 322 is rotatably connected to the mounting plate 33. When the second layer plate assembly 32 rotates to the front of the mounting plate 33, the second stop portion 332 can abut against the rear end of the second connecting member 322. By providing the second connecting member 322 at the rear end of the second layer rack 321, when the second layer plate assembly 32 rotates to the front of the mounting plate 33, since the second stop portion 332 abuts against the rear end of the second connecting member 322, the second connecting member 322, the second layer rack 321, and the mounting plate 33 form a continuous support structure, making the second layer rack 321 more stable when supporting items and avoiding the problems of sinking or loosening at the rear end of the second layer rack 321. Moreover, the front end of the second layer rack 321 can be supported on the second support rib 22, enabling the second layer rack 321 to be stably disposed in the refrigerating compartment 101.

[0114] As Figure 8 and Figure 9 As shown, in some embodiments, the second connecting member 322 may be provided with a second slot disposed toward the second layer rack 321. The rear end of the second layer rack 321 can be inserted into the second slot. By providing the second slot in the second connecting member 322 and inserting the rear end of the second layer rack 321 into the second slot, the connection area and contact points between the second connecting member 322 and the second layer rack 321 can be increased. Moreover, the insertion fit between the two can effectively avoid the problems of loosening or displacement of the second layer rack 321 caused by vibration or impact during use, improving the stability and reliability of the second layer rack 321 assembly.

[0115] In some embodiments, the second slot may extend along the length direction of the rear end of the second layer rack 321. Thereby, the entire front end of the second layer rack 321 is wrapped and fixed, further increasing the connection area between the second connecting member 322 and the second layer rack 321.

[0116] As Figure 9 As shown, in some embodiments, the front end of the first connecting member 312 may be convexly provided with a first limiting rib 313. The top of the first limiting rib 313 may be provided with a first limiting groove 301. When the mounting plate 33 rotates to the front of the first layer plate assembly 31, the first stop portion 331 can extend into the first limiting groove 301, and the bottom surface of the first stop portion 331 can be supported on the top surface of the first limiting rib 313.

[0117] Among them, by forming a first limiting groove 301 at the top of the first limiting rib 313, when the mounting plate 33 rotates to the front of the first layer plate assembly 31, that is, when the folding shelf mechanism 3 is in the unfolded state, the bottom surface of the first stopping portion 331 supports on the top surface of the first limiting rib 313, which can disperse the pressure of the mounting plate 33 and the first layer shelf 311 when carrying items, and improves the load-bearing capacity of the entire folding shelf mechanism 3. Moreover, the first limiting groove 301 is formed at the top of the first limiting rib 313, and the first stopping portion 331 can extend into the first limiting groove 301, which is beneficial to the part where the mounting plate 33 abuts against the first connecting member 312 to form a part of the first supporting plane, making the first supporting plane more continuous and flat.

[0118] As Figure 9 and Figure 10 shown, in some embodiments, a step can be formed at the front end of the first limiting rib 313 and the first connecting member 312. A first limiting groove 301 can be formed at the connection between the front end of the first limiting rib 313 and the first connecting member 312.

[0119] As Figure 9 shown, in some embodiments, the rear end of the second connecting member 322 can be convexly provided with a second limiting rib 323. A second limiting groove 306 can be provided at the top of the second limiting rib 323. When the second layer plate assembly 32 rotates to the front of the mounting plate 33, the first stopping portion 331 can extend into the second limiting groove 306, and the bottom surface of the second stopping portion 332 can support on the top surface of the second limiting rib 323.

[0120] Among them, by forming a second limiting groove 306 at the top of the second limiting rib 323, when the second layer plate assembly 32 rotates to the front of the mounting plate 33, that is, when the folding shelf mechanism 3 is in the unfolded state, the bottom surface of the second stopping portion 332 supports on the top surface of the second limiting rib 323, which can disperse the pressure of the mounting plate 33 and the second layer shelf 321 when carrying items, and improves the load-bearing capacity of the entire folding shelf mechanism 3. Moreover, the second limiting groove 306 is formed at the top of the second limiting rib 323, and the second stopping portion 332 can extend into the second limiting groove 306, which is beneficial to the part where the mounting plate 33 abuts against the second connecting member 322 to form a part of the first supporting plane, making the first supporting plane more continuous and flat.

[0121] As Figure 9 and Figure 10 shown, in some embodiments, a step can be formed at the rear end of the second limiting rib 323 and the second connecting member 322. A second limiting groove 306 can be formed at the connection between the rear end of the second limiting rib 323 and the second connecting member 322.

[0122] Figure 11 is Figure 5 another exploded view of;Figure 12 is Figure 11 a partial enlarged view of part B of

[0123] As Figure 11 and Figure 12 shown, in some embodiments, the folding shelf mechanism 3 may include a first rotating shaft member 34. The first connecting member 312 and the mounting plate 33 may be rotatably connected through the first rotating shaft member 34.

[0124] As Figure 7 and Figure 12 shown, in some embodiments, one end of the first connecting member 312 may be provided with a first connecting arm 314 extending towards the mounting plate 33. A first rotating hole 303 may be provided on the first connecting arm 314, and a first fixing hole 304 may be provided on the end face of the rear end of the mounting plate 33. One end of the first rotating shaft member 34 may be rotatably connected in the first rotating hole 303, and the other end of the first rotating shaft member 34 may be fixedly connected to the first fixing hole 304, so that the end face of the mounting plate 33 is rotatably provided on the front side of the first shelf 311.

[0125] Among them, the other end of the first rotating shaft member 34 may be fixedly connected to the first fixing hole 304, so that the whole of the first rotating shaft member 34 can be fixed on the rear end of the mounting plate 33. One end of the first rotating shaft member 34 passes through the first rotating hole 303, and the user can make the two rotate relative to each other by rotating the first connecting member 312 or the mounting plate 33.

[0126] As Figure 11 shown, in some embodiments, the first connecting arm 314 may be provided on the left and right sides of the first connecting member 312. The first rotating shaft member 34 may be respectively connected to the left and right sides of the mounting plate 33, so that the rotational connection structure between the first connecting member 312 and the mounting plate 33 is more stable, and the smoothness of the rotation between the first layer plate assembly 31 and the mounting plate 33 is improved.

[0127] In some embodiments, the first fixing hole 304 may be a threaded hole. The other end of the first rotating shaft member 34 may be provided with a thread adapted to the first fixing hole 304.

[0128] As Figure 12 shown, in some embodiments, the first rotating shaft member 34 may be a half-threaded screw. Using a half-threaded screw as the first rotating shaft member 34 can simplify the installation and disassembly process.

[0129] It should be noted that the half-threaded screw may have a threaded part and a smooth part. The threaded part can be fastened in the first fixing hole 304, and the smooth part is used to provide smoothness during rotation.

[0130] As Figure 11 andFigure 12 As shown, in some embodiments, the folding rack mechanism 3 may include a second rotating shaft member 35. The second connecting member 322 and the mounting plate 33 may be rotatably connected through the second rotating shaft.

[0131] As Figure 12 shown, in some embodiments, one end of the second connecting member 322 may be provided with a second connecting arm 324 extending towards the mounting plate 33. A second rotating hole 305 may be provided on the second connecting arm 324. A second fixing hole 306 may be provided on the end face of the front end of the mounting plate 33. One end of the second rotating shaft member 35 may be rotatably connected in the second rotating hole 305, and the other end of the second rotating shaft member 35 may be fixedly connected to the second fixing hole 306, so that the end face of the mounting plate 33 is rotatably arranged at the rear side of the second shelf 321.

[0132] As Figure 7 and Figure 12 shown, wherein, the other end of the second rotating shaft member 35 may be fixedly connected to the second fixing hole 306, so that the whole of the second rotating shaft member 35 can be fixed on the front end of the mounting plate 33. One end of the second rotating shaft member 35 passes through the second rotating hole 305, and the user can make the two rotate relative to each other by rotating the second connecting member 322 or the mounting plate 33.

[0133] In some embodiments, the second connecting arm 324 may be arranged on the left and right sides of the second connecting member 322. The second rotating shaft members 35 may be respectively connected to the left and right sides of the mounting plate 33, so that the rotational connection structure between the second connecting member 322 and the mounting plate 33 is more stable, and the smoothness of the rotation between the second shelf assembly 32 and the mounting plate 33 is improved.

[0134] In some embodiments, the second fixing hole 306 may be a threaded hole. The other end of the second rotating shaft member 35 may be provided with a thread adapted to the second fixing hole 306.

[0135] In some embodiments, the second rotating shaft member 35 may be a half-threaded screw. Using a half-threaded screw as the second rotating shaft member 35 can simplify the installation and disassembly process.

[0136] It should be noted that the half-threaded screw may have a threaded part and a smooth part. The threaded part can be fastened in the second fixing hole 306, and the smooth part is used to provide smoothness during rotation.

[0137] Figure 13 For Figure 2 the state diagram of the folding of the folding rack mechanism; Figure 14 For Figure 13 the schematic diagram from another perspective; Figure 15 For Figure 14 the partial enlarged view at C ofFigure 16 is Figure 3 The partial enlarged view of part D of

[0138] As Figure 14 and Figure 15 shown, in some embodiments, the first support rib 21 may have a first step 211 and a second step 212. The first step 211 can be used to support the first layer shelf 311, and the second step 212 can be used to support the second layer shelf 321 that is folded under the first layer shelf 311. By providing the first step 211 and the second step 212, the first layer plate assembly 31 and the second layer plate assembly 32 can stably support items at different positions, thereby effectively improving the overall load-bearing capacity of the device.

[0139] As Figure 2 shown, when the mounting plate 33 rotates to the front of the first layer plate assembly 31 and the second layer plate assembly 32 rotates to the front of the mounting plate 33, the rear end of the first layer plate assembly 31 can be supported on the first step 211, and the front end of the second layer plate assembly 32 can be supported on the second support rib 22, so that the top surfaces of the first layer plate assembly 31, the second layer plate assembly 32 and the mounting plate 33 can form a first support tabletop 300.

[0140] At this time, the folding layer shelf mechanism 3 is in the unfolded state. The first step 211 can support the first layer plate assembly 31, and the second support rib 22 can support the second layer plate assembly 32, so that the first support tabletop 300 formed by the top surfaces of the first layer plate assembly 31, the second layer plate assembly 32 and the mounting plate 33 has a large-area supporting surface, providing a larger storage space. At the same time, the first support rib 21 and the second support rib 22 provide good support force for the whole folding layer shelf mechanism 3, effectively improving the overall load-bearing capacity of the folding layer shelf mechanism 3 in the unfolded state.

[0141] As Figure 13 and Figure 14 shown, when the second layer plate assembly 32 rotates under the bottom surface of the first layer plate assembly 31, the rear end of the first layer plate assembly 31 can be supported on the first step 211, at least part of the second layer plate assembly 32 is located in the step space 201, and the bottom surface of the second layer plate assembly 32 can be supported on the second step 212, so that the first layer plate assembly 31 alone forms a second support tabletop 308.

[0142] As Figure 14 and Figure 15As shown, at this time, the folding rack mechanism 3 is in a folded state. The second layer board assembly 32 rotates and folds under the first layer board assembly 31. Since the rear end of the first layer board assembly 31 is supported on the first step 211, and the bottom surface of the second layer board assembly 32 is supported on the second step 212, the first support rib 21 can support the folding rack mechanism 3 in the folded state, thereby effectively dispersing the weight of the items and enhancing the load-bearing capacity of the entire support structure, avoiding the instability caused by weight concentration. In this way, when the folding rack mechanism 3 is in a folded state, the first layer board assembly 31 can independently form the second support tabletop 308, and the second support tabletop 308 can still serve as a stable tabletop to support heavy objects.

[0143] As Figure 16 shown, further, a step space 201 is formed between the front side of the first step 211 and the top surface of the second step 212, which can effectively accommodate part of the second layer board assembly 32 inside the step. It can not only play a good role in accommodating the folded second layer board assembly 32, but also the second layer board assembly 32 accommodated below can play a certain supporting role for the first layer board assembly 31, improving the load-bearing capacity of the folding rack mechanism 3 in the folded state.

[0144] It should be noted that at this time, the bearing area of the second support tabletop 308 is smaller than that of the first support tabletop 300. The second layer board assembly 32 is folded under the first layer board assembly 31, making the front of the first layer board assembly 31 vacant, facilitating the user to utilize the space in the refrigerating compartment 101 according to actual usage needs.

[0145] As Figure 16 shown, in some embodiments, the first support rib 21 can be L-shaped. The two right-angled sides of the L shape respectively correspond to the first step 211 and the second step 212.

[0146] In some embodiments, the folding rack mechanism 3 can include a decorative member 36. The decorative member 36 can be arranged at one end of the second layer board assembly 32 away from the mounting plate 33. The decorative member 36 can play a decorative role on the front side of the second layer board assembly 32.

[0147] As Figure 16 shown, in some embodiments, an installation groove 202 can be provided at one end of the second step 212 close to the first step 211, and the installation groove 202 can communicate with the step space 201. When the second layer board assembly 32 rotates to the bottom surface of the first layer board assembly 31, the bottom surface of the second layer board assembly 32 is supported on the second step 212, and the decorative member 36 is received in the installation groove 202.

[0148] In this way, when the folding rack mechanism 3 is in the folded state, the decorative member 36 is received in the installation groove 202, preventing interference between the decorative member 36 and the first layer board assembly 31.

[0149] As Figure 15 shown, in some embodiments, the upper and lower ends of the decorative member 36 can abut between the lower side of the first layer board assembly 31 and the bottom wall of the installation groove 202. When the second layer board assembly 32 is folded under the first layer board assembly 31, the bottom end face of the second layer board assembly 32 can abut on the decorative member 36, preventing direct contact and friction between the first rack 311 and the second rack 321, which may affect the appearance of the second layer board assembly 32.

[0150] In some embodiments, the decorative member 36 can be made of an elastic silicone member.

[0151] As Figure 3 shown, in some embodiments, the top support surface of the first step 211 and the top support surface of the second support rib 22 can be at the same height in the refrigerating compartment 101. In this way, when the folding rack mechanism 3 is in the unfolded state, since the bottom supports of the front and rear first rack 311 and second rack 321 are at the same height, it is beneficial for the first support table surface 300 formed by the folding rack mechanism 3 in the unfolded state to be on the same horizontal plane, thereby providing a more stable support for the articles.

[0152] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the scope of the present application is only limited by the appended claims.
