[0082] In some embodiments of the present application, a refrigeration device is provided. The refrigeration device may be a device for refrigeration such as a refrigerator or a freezer, and includes:

[0083] The box body 100 comprises a box shell;

[0084] and an inner liner component 110 disposed in the box shell, wherein a storage space 120 for storing items is defined inside the inner liner component 110;

[0085] In some embodiments of the present application, the storage space 120 includes a refrigerator compartment and a freezer compartment arranged up and down.

[0086] The refrigerating chamber and the freezing chamber have openings, and door bodies are arranged correspondingly at the opening positions. The door bodies are rotatably connected to the box body 100 to realize opening or closing of the refrigerating chamber and the freezing chamber.

[0087] In this embodiment, the end of the refrigeration device close to the opening is defined as the front end, and the end opposite to the opening is defined as the rear end.

[0088] A support frame 200 is arranged in the storage space 120 and fixed on the inner tank component 110;

[0089] In some embodiments of the present application, the supporting frame 200 includes a frame body 210 .

[0090] The shelf assembly is foldable. When in use, the various shelf components constituting the shelf assembly can be operated according to different usage conditions so that it has different usage states.

[0091] In some embodiments of the present application, the shelf assembly includes: a first shelf component 310, which is fixedly mounted on the supporting frame 200, and the first shelf component 310 is always in an unfolded state to ensure that it can be used to carry and place items.

[0092] In some embodiments of the present application, the first layer frame component 310 includes a first layer frame body 410 and a first layer frame glass plate 420 embedded in the first layer frame body 410. In order to simplify the injection molding process and reduce the production cost, during the setting, the frame body 210 of the supporting frame 200 and the first layer frame body 410 are injection molded as one piece to ensure that the connection between the first layer frame component 310 and the supporting frame 200 is fixed.

[0093] There are two rack bodies 210 arranged at both sides of the first rack frame 410 .

[0094] In some embodiments of the present application, the first shelf component 310 is assembled at one end of the back plate of the supporting frame 200 close to the inner tank component 110. Since it is fixed to the supporting frame 200, it cannot be adjusted during adjustment.

[0095] The second shelf component 320 is slidably connected to the supporting frame 200, and can be slid relative to the supporting frame 200 to be unfolded or folded and stored to a position below the first shelf component 310;

[0096] When in use, the second shelf component 320 can be extended relative to the first shelf component 310 by sliding along the supporting frame 200 to achieve its expansion, and finally arranged side by side with the first shelf component 310 to meet the demand for storing a large number of items.

[0097] At the same time, it can also be folded to a position below the first shelf component 310 by sliding downward along the supporting frame 200 .

[0098] The third shelf component 330 is slidably connected to the supporting frame 200 and the second shelf component 320 , and can slide relative to the supporting frame 200 and the second shelf component 320 .

[0099] The third shelf member 330 can be unfolded or folded by sliding between the supporting frame 200 and the second shelf member 320;

[0100] Before folding, the third shelf component 330 is in an unfolded state, and is supported and positioned at the front section of the supporting frame 200. When folding is required, the second shelf component 320 can be slid from the supporting frame 200 into the second shelf component 320 to be stored inside the second shelf component 320;

[0101] When unfolding, the third shelf member 330 is slid along the second shelf member 320 and slid from the second shelf member 320 to a position to support the carrier 200 for unfolding.

[0102] Since the third shelf component 330 is folded and stored in the second shelf component 320, when the second shelf component 320 needs to be unfolded, the second shelf component 320 is pushed to slide along the supporting frame 200, and at the same time, the third shelf component 330 stored therein is driven to move together with it to open the second shelf component 320 and the third shelf component 330 synchronously;

[0103] When the third shelf component 330 needs to be unfolded, the third shelf component 330 is pushed to slide outward from the second shelf component to the bearing support frame.

[0104] When the second shelf component 320 and the third shelf component 330 are both in the storage state, the first shelf component 310 and the second shelf component 320 are arranged in sequence from top to bottom, and the third shelf component 330 is stored inside the second shelf component 320.

[0105] When the second shelf component 320 and the third shelf component 330 are both in the unfolded state, the first shelf component 310, the second shelf component 320 and the third shelf component 330 are sequentially arranged side by side.

[0106] In the present embodiment, the refrigeration equipment improves the shelf assembly structure, and the shelf assembly is configured to include three shelf components. When in use, the third shelf component 330 can be separately stored by sliding it along the load-bearing support frame to slide it into the second shelf component 320.

[0107] At this time, the second shelf component 320 and the first shelf component 310 are in a side-by-side unfolded state, and the user can place items on the first shelf component 310 and the second shelf component 320 according to actual use needs, and the shelves are in a partially folded state;

[0108] When in use, the user can slide the third shelf component 330 from the load-bearing support frame to the inside of the second shelf component 320, and then drive the second shelf component 320 to slide the third shelf component 330 to the lower position of the first shelf component 310, so as to store the second shelf component 320 and the third shelf component 330 at the same time. At this time, only the first shelf component 310 is used to place items, and the shelf assembly is in a completely folded state;

[0109] When it is necessary to unfold all the shelf components, force can be applied to the second shelf component 320 first, so that the second shelf component 320 slides out along the supporting frame 200. After the second shelf component 320 is unfolded into place, force can be applied to the third shelf component 330 to slide and stretch the third shelf component 330 from the second shelf component 320 to the supporting frame to achieve unfolding, thereby finally achieving the effect of the second shelf component 320 and the third shelf component 330 being stretched and unfolded in sequence.

[0110] By improving the structure of the shelf assembly, the shelf assembly can have three different usage states when in use: fully expanded, partially folded, and fully folded. When in use, the user can slide the second shelf component 320 or the third shelf component 330 according to the size of the items to be placed and the size of the space to be reserved, so as to switch between different usage states, thereby meeting the user's needs for diverse usage.

[0111] In some embodiments of the present application, in order to achieve support for both sides of the shelf assembly, two rack bodies 210 are correspondingly provided and arranged symmetrically.

[0112] The frame body 210 is formed with a second track segment 220 , which is used to form a sliding track for the second layer frame component 320 . When the second layer frame component 320 slides, it slides along the second track segment 220 .

[0113] In some embodiments of the present application, the second track segment 220 includes:

[0114] The second main track portion 221 is a second main track segment, which is formed by the second track ribs on the frame body 210 and is used to form the main sliding track of the second layer frame component 320;

[0115] The second guide rail portion 222 is connected to the second main rail portion 221;

[0116] The second guide rail portion 222 is a second guide rail segment, which is arranged to tilt upward to form a guide support rail for the sliding of the second shelf component 320 to prevent the second shelf component 320 from tipping over during the sliding process.

[0117] The second guide track segment is formed by the second guide track ribs on the frame body 210 .

[0118] The second shelf component 320 includes:

[0119] The second shelf frame 321 is injection molded to form a mounting frame for the second shelf component 320;

[0120] The second layer frame glass plate is embedded and fixed in the second layer frame body 321 .

[0121] In some embodiments, a second extension portion 322 is formed extending from one side of the second shelf frame 321, and a third sliding portion 324 and a second sliding portion 323 are formed at both ends of the second extension portion 322;

[0122] The second extension portion 322 is an extension platform extending from one side of the second shelf frame 321 , and can be integrally injection-molded with the second shelf frame 321 during molding.

[0123] The second sliding portion 323 is formed at the front end of the second extending portion 322 , and the third sliding portion 324 is correspondingly arranged at the rear end of the second extending portion 322 , and is arranged opposite to the second sliding portion 323 .

[0124] In some embodiments, the second sliding portion 323 is a second sliding protrusion or a second sliding block, and the third sliding portion 324 is a third sliding protrusion or a third sliding block.

[0125] When the second shelf component 320 slides along the supporting frame 200 , the second sliding portion 323 is clamped on the second main rail portion 221 and slides along the second main rail portion 221 , and the third sliding portion 324 slides along the second guide rail portion 222 .

[0126] When the second shelf component 320 slides out relative to the supporting frame 200, if only the second sliding part 323 and the second main track part 221 are provided, when the length of the sliding-out part of the second shelf component 320 exceeds half of the length, it may overturn and collide with the first shelf component 310 due to the heavy weight of the sliding-out section, causing the glass plates of the first shelf component 310 and the second shelf component 320 to collide and be damaged.

[0127] To avoid the above problems, a second guide rail portion 222 is provided at the front side of the second main rail portion 221 , which is used to cooperate with the third sliding portion 324 located on the second shelf component 320 to support the front end of the second shelf component 320 .

[0128] When sliding, the second sliding part 323 slides along the second main rail part 221, and the third sliding part 324 slides along the second guide rail part 222, so that the front and rear ends of the second shelf part 320 can slide along the corresponding rails during the sliding process, which not only ensures that the second shelf part 320 can move along the predetermined rail and trajectory, but also ensures the stability of the second shelf part 320 during the sliding process.

[0129] In some embodiments of the present application, the second main rail portion 221 includes a main inclined rail segment, which is arranged to be inclined downward, and a straight rail segment connected to the main inclined rail segment, and the straight rail segment is arranged close to the rear end of the supporting frame 200.

[0130] The inclined main inclined track section can guide the second shelf component 320 to slide up and down, so as to facilitate the sliding of the second shelf component 320;

[0131] The straight rail section is straight so as to stably support the second shelf member 320 that has slid into place.

[0132] In some embodiments, the second guide rail portion 222 is a second guide rail segment that is arranged to be tilted downward. By tilting downward, the second shelf component 320 can slide downward quickly for storage under the action of weight, and when unfolding, it can also be guided by the tilted second guide rail segment to ensure that it can slide out.

[0133] In some embodiments of the present application,

[0134] A second positioning structure cooperating with the second shelf component 320 is formed on the supporting frame 200 , and the second positioning structure can be used to support and position the second shelf component 320 in the unfolded state.

[0135] In some embodiments, the second positioning structure includes:

[0136] The second positioning protrusion 223 is formed at the joint position between the second main track portion 221 and the second guide track portion 222 ; the second positioning protrusion 223 is a second positioning boss, and is integrally injection-molded with the second track segment 220 during molding.

[0160] The third clamping portion 231 is a third clamping opening formed at the front side of the third track segment 230 .

[0161] A fourth extension portion 332 is formed on the third shelf component 330 . The fourth extension portion 332 is a fourth extension platform, which is directly integrally injection-molded with the third shelf frame 338 .

[0162] A third positioning protrusion 3321 is formed on the fourth extending portion 332 . When the third shelf component 330 is slidably unfolded relative to the second shelf component 320 , the third positioning protrusion 3321 is clamped in the third clamping portion 231 .

[0163] The third positioning protrusion 3321 is locked in the third locking portion 231 to achieve the limiting and fixing of the front end of the third shelf component 330 .

[0164] In some embodiments of the present application,

[0165] The third shelf component 330 is formed with:

[0166] The fifth extension portion 333 is extended along the length direction of the third shelf frame 338. The fifth extension portion 333 is a fifth extension platform integrally formed with the third shelf frame 338 and extends along the length of the second shelf.

[0167] A protruding platform 334 is formed near the front end of the supporting frame 200 on the fifth extension portion 333 , a recessed portion 335 is formed in the protruding platform 334 , and a limiting portion 336 is formed on one side of the protruding platform 334 ;

[0168] The recessed portion 335 is a recessed groove having a notch, and the limiting portion 336 is a limiting protrusion arranged on one side of the raised platform 334 and is integrally injection-molded with the raised platform 334 .

[0169] The third track segment 230 is formed with a bent portion 232 bent toward the recessed portion 335 ;

[0170] The curved portion 232 is formed by protruding from the third track segment 230 and is bent in an arc shape so as to extend to the position of the recessed portion 335 and cooperate with the recessed portion 335 .

[0171] When the third shelf component 330 is in the unfolded state, the end of the bent portion 232 is stuck in the recessed portion 335 .

[0172] When the third frame member 330 needs to be folded, the third frame member 330 is lifted to separate the bent portion 232 from the recessed portion 335 .

[0173] The bent portion 232 is located at the rear side of the third clamping portion 231, and the recessed portion 335 is also correspondingly arranged near the third positioning protrusion 3321. The cooperation between the bent portion 232 and the recessed portion 335 and the cooperation between the third positioning protrusion 3321 and the third clamping portion 231 realizes the positioning support for the front section of the entire third shelf component 330.

[0174] In some embodiments of the present application, the third rail segment 230 includes a third rail body portion 233;

[0175] The third rail body portion 233 is a third rail body segment.

[0176] And a raised rib 234 is formed on the third rail body portion 233 and connected to the bottom end of the curved portion 232 . The raised rib 234 is a raised rib formed from the third rail body segment. The raised rib is rectangular and is used to connect to the bottom of the curved portion 232 .

[0177] A first sliding channel 235 for the raised platform 334 to slide is formed between the raised rib 234 and the curved portion 232 . After the curved portion 232 and the recessed portion 335 are separated, the raised platform 334 forming the recessed portion 335 can slide downward along the first sliding channel 235 .

[0178] During sliding, the limiting portion 336 on one side of the raised platform 334 can be clamped on the outer side of the curved portion 232 to limit the third shelf component 330 to prevent it from falling off during the sliding process.

[0179] In some embodiments, the first sliding channel 235 is configured to include at least one curved section extending downward, which can be mainly used to ensure that the third shelf component 330 can automatically slide downward along the first sliding channel under the action of gravity to achieve folding and storage.

[0180] In some embodiments, the top surface of the curved portion 232 is formed with an arc surface, which constitutes an arc channel section, and the top surface of the raised rib portion 234 is formed with a flat surface connected thereto, which constitutes a flat channel section. When the raised portion slides, it can slide along the arc surface to the flat surface to achieve an automatic sliding effect.

[0181] In some embodiments, a folded rib 236 is formed on the third rail body 233, which is arranged opposite to the bending portion 232 and extends along the length direction of the third rail body 233, and a second sliding channel 237 for the sliding of the third positioning protrusion 3321 is formed between it and the bending portion 232 and the raised rib 234.

[0182] The folding rib portion 236 is a folding rib, which is arranged perpendicular to the third rail body portion 233. When the third shelf component 330 slides downward, it can also slide downward along the second passage through the third positioning protrusion 3321.

[0183] When the second shelf component 320 is folded, stored or unfolded, it can slide along the second passage through the third positioning protrusion 3321, and the protrusion platform 334 can slide along the first passage. The double-channel cooperation ensures that the third shelf component 330 can slide smoothly along the set sliding trajectory to the sliding track section 326 on the second shelf component 320.

[0184] In some embodiments of the present application, the second sliding channel:

[0185] At least includes a first inclined portion 2371 and a second inclined portion 2372 connected in sequence, wherein the inclination angle of the first inclined portion 2371 is greater than that of the second inclined portion 2372;

[0186] And a third straight portion 2373 connected to the end of the second inclined portion 2372 .

[0187] The first inclined portion 2371 is a first inclined surface, a second inclined surface, and a third straight surface formed at the bottom of the second passage.

[0188] The first inclined surface has a large inclination angle to ensure that the third positioning protrusion 3321 can slide down under gravity in the initial state. The second inclined surface has a small inclination angle to enable the third positioning protrusion 3321 to slide down steadily during the sliding process.

[0189] In some embodiments of the present application, a support portion 337 is formed at the rear end of the third frame body 338 . The support portion 337 is located on the fourth extension portion 332 and is arranged perpendicular to the third frame body 338 .

[0190] The support portion 337 is a support guide protrusion, which is arranged at two end positions of the fourth extending portion 332 opposite to the third positioning protrusion 3321 .

[0191] In order to increase the supporting strength, the supporting guide protrusion is provided with reinforcing ribs on both sides.

[0192] When the third frame component 330 is in the unfolded state, the support portion 337 is pressed against the third straight portion 2373, and the rear end of the third frame component 330 is supported and positioned by the support portion 337, while the front section is supported and positioned by the curved portion 232 against the recessed portion 335.

[0193] A sliding guide portion 238 is formed at the end of the third track segment 230 close to the second sliding channel 237. The sliding guide portion 238 is arranged to be inclined downward to guide the support portion 337 when it slides downward.

[0194] The sliding guide portion 238 is a sliding guide inclined surface or a sliding guide curved surface formed at the end of the second sliding channel 237, and guides the support portion 337 when the third shelf component 330 slides toward the second shelf component 320 side.

[0195] Although the support portion 337 may be suspended in the air after sliding out along the sliding guide surface, the first sliding channel 235 and the second sliding channel 237 on the front side can correspondingly support and limit the third shelf component 330 as a whole, ensuring that the third shelf component 330 will not deviate from the sliding track and can slide onto the set second shelf component 320.
