[0026] An embodiment of the present application provides a refrigeration device 10. The refrigeration device 10 includes a box body 11 and a shelf assembly 12. The shelf assembly 12 is arranged in the box body 11. The shelf assembly 12 includes a first shelf 121, a second shelf 122 and a support frame 123. The first shelf 121 and the second shelf 122 are both arranged on the support frame 123. The support frame 123 is a foldable support frame 123. When the support frame 123 is in an unfolded state, the first shelf 121 and the second shelf 122 are arranged in the same plane. When the support frame 123 is in a folded state, the first shelf 121 and the second shelf 122 are arranged in a stacked state.

[0027] It can be known from the above structure that the first shelf 121 and the second shelf 122 can be used to place articles, and the first shelf 121 and the second shelf 122 are arranged on the support frame 123, and the support frame 123 can play a good supporting role for the first shelf 121 and the second shelf 122. The support frame 123 is set as a foldable bracket. When the support frame 123 is in the unfolded state, the first shelf 121 and the second shelf 122 are arranged in the same plane, and when the support frame 123 is in the folded state, the first shelf 121 and the second shelf 122 are arranged in a stacked manner. At this time, the first shelf 121 and the second shelf 122 can store articles when the support frame 123 is in the unfolded state and the folded state, and will not cause waste of space in the box body 11. When the support frame 123 is in a folded state, the first shelf 121 and the second shelf 122 can present a double-layer structure. At this time, since the support frame 123 is folded, not only the first shelf 121 and the second shelf 122 can still store items to increase the storage space in the box body 11, but also the height of the first shelf 121 originally located in the first plane A is increased, so that the box body 11 can be compatible with the storage of items of various sizes, which can well meet the multiple needs of consumers.

[0028] See also Figures 1 to 4 , Figure 4 It is a schematic structural diagram of the shelf assembly of the refrigeration equipment of the present application in a folded state.

[0029] Specifically, when the support frame 123 is in the unfolded state, the first shelf 121 and the second shelf 122 are arranged in parallel, and the first shelf 121 and the second shelf 122 are both located on the first plane A. At this time, the first shelf 121 and the second shelf 122 are used together for storing items. When the support frame 123 is in the folded state, the first shelf 121 moves to the second plane B, and the second shelf 122 is located on the first plane A, and the first plane A and the second plane B are parallel. At this time, not only will the storage function of the first shelf 121 not be wasted, but the first shelf 121 and the second shelf 122 can both be used for storing items. At the same time, since the first shelf 121 and the second shelf 122 are located on the first plane A and the second plane B respectively, the first shelf 121 and the second shelf 122 can present a double-layer structure, thereby increasing the height of the first shelf 121 at the position originally located in the first plane A, so that the box 11 can be compatible with the storage of items of various sizes, so as to better meet the multiple needs of consumers.

[0030] Preferably, when the support frame 123 is in the folded state, the second plane B may be located above the first plane A, and at this time, the first shelf 121 is located above the second shelf 122. Of course, in some other embodiments, when the support frame 123 is in the folded state, the first plane A may also be located above the second plane B, and at this time, the second shelf 122 is located above the first shelf 121, which is not limited here.

[0031] In one embodiment of the present application, the box body 11 has a back wall surface 111, and the support frame 123 is fixed to the back wall surface 111. The support frame 123 is two triangular support frames 1231 arranged in parallel along the first direction X. The triangular support frame 1231 includes a fixed frame 1232, a support base frame 1233 and a cantilever 1236. Among them, the fixed frame 1232 extends along the second direction Y. The fixed frame 1232 is arranged on the back wall surface 111. The cantilever 1236 includes a first cantilever 1238 and a second cantilever 1239. The first cantilever 1238 is connected to one end of the fixed frame 1232, and the second cantilever 1239 is rotatably connected to one end of the first cantilever 1238 away from the fixed frame 1232. The support base frame 1233 includes a first base frame 1234 and a second base frame 1235. The first base frame 1234 is connected to one end of the fixed frame 1232 away from the first cantilever 1238, and extends along the third direction Z. The second base frame 1235 is connected to an end of the second cantilever 1239 away from the first cantilever 1238. The first shelf 121 is arranged on the second base frame 1235, and the second shelf 122 is arranged on the first base frame 1234. The first direction X, the second direction Y and the third direction Z are mutually perpendicular. When the support frame 123 is in the unfolded state, the first base frame 1234 abuts against the second base frame 1235, and when the support frame 123 is in the folded state, the second cantilever 1239 rotates to abut against the first cantilever 1238.

[0032] Specifically, the setting of the fixing frame 1232 can fix the entire triangular support frame 1231 on the back wall surface 111, so that when the first shelf 121 and the second shelf 122 are placed on the support frame 123, the triangular support frame 1231 can maintain good stability. The setting of the supporting base frame 1233 can respectively provide good support for the first shelf 121 and the second shelf 122. The setting of the cantilever 1236 can also provide a certain support for the supporting base frame 1233, so as to avoid the phenomenon of sinking of the supporting base frame 1233 due to its own gravity during long-term use.

[0033] Furthermore, when the support frame 123 is in the unfolded state, the first bottom frame 1234 and the second bottom frame 1235 are in contact with each other. At this time, the first shelf 121 and the second shelf 122 are arranged in the same plane, and the first shelf 121 and the second shelf 122 are used together for storing articles. When the support frame 123 is in the folded state, the second cantilever 1239 rotates to abut against the first cantilever 1238. At this time, the first shelf 121 rotates to the second plane B under the rotation of the second cantilever 1239, so that the first shelf 121 and the second shelf 122 can present a double-layer structure, thereby increasing the height of the first shelf 121 at the position originally located in the first plane A. At this time, the box body 11 can be compatible with the storage of articles of various sizes to better meet the multiple needs of consumers.

[0034] Preferably, the first cantilever 1238 and the second cantilever 1239 have the same length. The first base frame 1234 and the second base frame 1235 have the same length. At this time, the areas of the first shelf 121 and the second shelf 122 are equal. When the support frame 123 is in the folded state, the second cantilever 1239 rotates 180°, at which time the second cantilever 1239 overlaps with the first cantilever 1238, and the shelf assembly 12 presents a rectangular form, which is more beautiful in overall structure. At the same time, the space occupied by the shelf assembly 12 in the box 11 is also minimal. In addition, since the first shelf 121 flips 180° to the second plane B, the height of the first shelf 121 originally located in the first plane A is higher, which can make the box 11 compatible with the storage of items of various sizes, so as to better meet the multiple needs of consumers.

[0035] Optionally, in some other embodiments, the lengths of the first cantilever 1238 and the second cantilever 1239 are not equal, and the length of the first cantilever 1238 is greater than the length of the second cantilever 1239. Similarly, the length of the first base frame 1234 and the length of the second base frame 1235 are also different, and the length of the first base frame 1234 is greater than the length of the second base frame 1235. At this time, when the second cantilever 1239 rotates to rotate the first shelf 121 to the second plane B, the first shelf 121 and the second shelf 122 can also be used to place items, and can also meet the storage needs of items of various sizes in the box 11, and there is no limitation here.

[0036] When the shelf assembly 12 is in the folded state, in order to prevent the second cantilever 1239 from sliding down due to its own gravity, in one embodiment of the present application, a plurality of protrusions 124 are formed on the first cantilever 1238, and a plurality of grooves 125 are formed on the second cantilever 1239 corresponding to the protrusions 124. When the shelf assembly 12 is in the folded state, the protrusions 124 are clamped in the grooves 125. At this time, the connection strength between the first cantilever 1238 and the second cantilever 1239 can be increased by clamping the protrusions 124 and the grooves 125, so that the second cantilever 1239 can be prevented from sliding down due to its own gravity, so as to better improve the overall stability of the shelf assembly 12 in the folded state, thereby improving the user experience.

[0037] Optionally, in some other embodiments, a plurality of grooves 125 may be provided on the first cantilever 1238, and a plurality of protrusions 124 may be provided on the second cantilever 1239 corresponding to the grooves 125. When the shelf assembly 12 is in the folded state, the protrusions 124 are clamped in the grooves 125. At this time, the connection strength between the first cantilever 1238 and the second cantilever 1239 can be increased by clamping the grooves 125 and the protrusions 124, so as to prevent the second cantilever 1239 from sliding downward due to its own gravity, thereby improving the overall stability of the shelf assembly 12 in the folded state. At the same time, the clamping method is more convenient and quick in installation operation, and is easier for production personnel to operate. The clamping method can also avoid installation errors, thereby improving the qualified rate of product production. In addition, the clamping of the protrusions 124 and the grooves 125 can also reduce the number of other structural parts, thereby reducing costs.

[0038] It should be noted that the protrusion 124 and the cantilever 1236 are integrally formed, or the protrusion 124 and the cantilever 1236 can also be connected by welding or gluing, which is not limited here.

[0039] In one embodiment of the present application, the triangular support frame 1231 further includes a first connecting frame 1261 and a second connecting frame 1262. The first connecting frame 1261 connects the first cantilever 1238 and an end of the first base frame 1234 away from the fixed frame 1232. The second connecting frame 1262 connects the second cantilever 1239 and an end of the second base frame 1235 close to the first base frame 1234. The provision of the first connecting frame 1261 and the second connecting frame 1262 can not only improve the bearing capacity of the supporting base frame 1233 to improve the overall bearing capacity of the shelf assembly 12, but also improve the structural rigidity of the shelf assembly 12 by improving the structural rigidity of the supporting base frame 1233, thereby making the overall structure of the shelf assembly 12 more stable.

[0040] Preferably, the first connecting frame 1261 and the second connecting frame 1262 are of the same length. Specifically, when the shelf assembly 12 is in the unfolded state, the first connecting frame 1261 and the second connecting frame 1262 are arranged side by side and overlapped. When the shelf assembly 12 is in the folded state, the second connecting frame 1262 rotates to the end of the first connecting frame 1261 away from the second shelf 122. And when the shelf assembly 12 is in the folded state, the sum of the lengths of the second connecting frame 1262 and the first connecting frame 1261 is consistent with the length of the fixed frame 1232. At this time, the shelf assembly 12 presents a rectangular state, and the first shelf 121 and the second shelf 122 can both be used to place items. At the same time, after the first shelf 121 is flipped to the second plane B, the space at the original position of the first shelf 121 is increased, which can also make the box 11 compatible with the storage of items of various sizes, so as to better meet the multiple needs of consumers.

[0041] Furthermore, the triangular support frame 1231 further includes a third connecting frame 1263 and a fourth connecting frame 1264. Among them, one end of the third connecting frame 1263 is connected to one end of the first cantilever 1238 away from the fixed frame 1232, and the other end is connected to one end of the fixed frame 1232 connected to the first base frame 1234. One end of the fourth connecting frame 1264 is connected to one end of the first cantilever 1238 away from the fixed frame 1232, and the other end is connected to the fixed frame 1232. The arrangement of the third connecting frame 1263 and the fourth connecting frame 1264 can divide the support frame 123 structure into a plurality of triangular structures. Since the triangular structure has good structural rigidity, the arrangement of the third connecting frame 1263 and the fourth connecting frame 1264 can well improve the overall structural strength of the support frame 123, so as to avoid deformation of the support frame 123 when the weight of the items placed on the first shelf 121 and the second shelf 122 is large, thereby affecting the user experience. Therefore, the third connecting frame 1263 and the fourth connecting frame 1264 can improve the structural strength of the support frame 123, thereby improving the load-bearing capacity of the shelf assembly 12, thereby improving the user experience.

[0042] Preferably, one end of the fourth connecting frame 1264 is connected to one end of the first cantilever 1238 away from the fixing frame 1232, and the other end is connected to the fixing frame 1232 and parallel to the first base frame 1234. At this time, the appearance of the entire support frame 123 has a certain symmetry, and the overall appearance is more beautiful.

[0043] It should be noted that the first connecting frame 1261, the second connecting frame 1262, the third connecting frame 1263 and the fourth connecting frame 1264 are all integrally formed on the triangular support frame 1231, and the structural strength is greater. Of course, in some other embodiments, it can also be achieved by welding, gluing, etc., which is not limited here.

[0044] In one embodiment of the present application, the shelf assembly 12 further includes a connector 127. The connector 127 is disposed on the fixing frame 1232. The triangular support frame 1231 is connected to the back wall surface 111 through the connector 127. Since the fixing frame 1232 itself is relatively small in size, the direct connection of the fixing frame 1232 with the back wall surface 111 will result in a small contact area between the fixing frame 1232 and the back wall surface 111, and thus its overall stability is relatively weak. Therefore, when the weight of the items placed on the first shelf 121 and the second shelf 122 is relatively large, it is easy to cause the first shelf 121 and the second shelf 122 to collapse, etc., affecting the user experience. Therefore, providing the connecting piece 127 can increase the contact area between the fixing frame 1232 and the back wall surface 111. At this time, the connection strength between the fixing frame 1232 and the back wall surface 111 is higher, the overall structure of the support frame 123 is more stable, the first shelf 121 and the second shelf 122 can also withstand heavier items, the overall adaptability of the shelf assembly 12 is also better, and the user experience is better.

[0045] Specifically, a clamping block 1271 is formed on the fixing frame 1232, and a clamping groove 1272 is formed on one end of the connecting member 127 facing the fixing frame 1232, corresponding to the clamping block 1271. The clamping block 1271 is clamped in the clamping groove 1272. By clamping the clamping block 1271 and the clamping groove 1272, not only the connection strength between the fixing frame 1232 and the connecting member 127 can be increased, but also the clamping method is more convenient and quick in installation operation, and the production personnel are easier to operate. In addition, the clamping method can also avoid installation errors, thereby improving the qualified rate of product production. In addition, the clamping block 1271 and the clamping groove 1272 are clamped, which can also reduce the number of other structural parts, thereby reducing costs.

[0046] Preferably, the clamping block 1271 is integrally formed with the fixing frame 1232. In this case, the connection strength between the clamping block 1271 and the fixing frame 1232 is stronger. Of course, in some other embodiments, the clamping block 1271 can also be connected to the fixing frame 1232 by welding, gluing, etc., which is not limited here.

[0047] In one embodiment of the present application, the box body 11 further includes two side walls 112 arranged opposite to each other. A convex ridge (not shown in the figure) is formed on the side wall 112, and the support base 1233 is placed on the convex ridge. The structure of the convex ridge can share the gravity borne by the support base 1233, and then play a certain supporting role on the support base 1233, so that the gravity borne by the support base 1233 can be greater, so that the first shelf 121 and the second shelf 122 can place heavier items, thereby greatly improving the adaptability of the shelf assembly 12 and improving the consumer's experience.

[0048] It should be noted that the terms "horizontal", "vertical" and the like do not mean that the components are absolutely horizontal or vertical, but can be slightly tilted; the terms "parallel", "vertical" and the like do not mean that the components are absolutely parallel or vertical, but can form a certain angle deviation. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted. In addition, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the product of the present application is usually placed when used, which is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0049] It is to be understood that the meaning of "plurality" herein is at least two, such as two, three, etc., unless there is a special limitation. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices. The term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " herein generally indicates that the associated objects before and after are in an "or" relationship.

[0050] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
