In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0068] 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.

[0069] Refrigeration equipment includes:

[0070] A box body 100, wherein a storage space is formed inside the box body 100;

[0071] In some embodiments of the present application, the storage space includes a refrigerator and a freezer compartment arranged up and down.

[0072] The box body 100 includes a box shell and an inner liner component 110 arranged in the box shell. The inner liner component 110 defines a refrigerating chamber and a freezing chamber respectively, so as to realize refrigerated and frozen storage of food.

[0073] 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.

[0074] 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.

[0075] A support frame 200 is arranged in the storage space and assembled on the wall of the inner tank component 110;

[0076] In some embodiments, a hanging protrusion is provided on the inner liner component 110 , and the support frame 200 is hung and fixed on the inner liner component 110 .

[0077] In some embodiments of the present application, the support frame 200 includes a frame body and connecting frames symmetrically arranged on both sides of the frame body. During molding, the connecting frames and the frame body can be integrally formed by injection molding.

[0078] A shelf assembly, which is foldable and arranged in the storage space, and the shelf assembly at least comprises:

[0079] The first shelf component 300 is assembled in the support frame 200;

[0080] In some embodiments of the present application, the first layer frame component 300 includes a first layer frame glass plate, a hollow portion is formed on the frame body, and a first layer frame mounting frame is formed on the frame body around the hollow portion. The first layer frame glass plate is inserted and fixed in the first layer frame mounting frame to achieve integrated fixation with the support frame 200.

[0081] Directly forming the first shelf installation frame for installing the first shelf glass plate through the support frame 200 can not only realize the integral and firm connection and fixation between the first shelf component 300 and the support frame 200, but also simplify the manufacturing process and reduce the cost.

[0082] In some embodiments of the present application, the first shelf component 300 is assembled at one end of the support frame 200 close to the inner liner component 110. Since it is fixed to the support frame 200, it cannot be adjusted during adjustment. When setting, it can be placed close to the rear side so that the foldable shelf can be set at the front side for folding, opening or storage.

[0083] In some embodiments of the present application, the shelf assembly includes a second shelf component 400, which is slidably connected to the support frame 200 and can slide relative to the support frame 200 to be stored under the first shelf component 300;

[0084] The second shelf component 400 is configured to be slidable along the support frame 200 , so that it can easily change its position by sliding relative to the support frame 200 and can at least be slidably stored to a position below the first shelf component 300 .

[0085] The third shelf component 500 is slidably connected to the support frame 200 and can be slid relative to the support frame 200 to be stored under the second shelf component 400;

[0086] Since the third shelf component 500 can slide along the support frame 200 alone, it can also be stored under the first shelf component 300 by sliding.

[0087] When the second shelf member 400 and the third shelf member 500 are both slid and stored, the first shelf member 300 , the second shelf member 400 and the third shelf member 500 are sequentially arranged from top to bottom.

[0088] The third shelf component 500 can also be slid and unfolded relative to the support frame 200 and simultaneously drive the second shelf component 400 to slide and unfold so that it can be unfolded side by side with the second shelf component 400 and the first shelf component 300.

[0089] In this embodiment, the refrigeration device improves the structure of the shelf assembly, and the shelf assembly is set to include at least three shelf components. When in use, the third shelf component 500 can be separately stored by sliding it along the support frame 200 to a position below the first shelf component 300. At this time, the second shelf component 400 and the first shelf component 300 are in a side-by-side unfolded state. The user can place items on the first shelf component 300 and the second shelf component 400 according to actual use needs, and the shelves are in a partially folded state.

[0090] Of course, the user can also slide the third shelf component 500 to be stored under the first shelf component 300, and then slide the second shelf component 400 to be stored under the first shelf component 300, so that it is located between the first shelf component 300 and the second shelf component 400. At this time, only the first shelf component 300 is used to place items, and the shelf is in a completely folded state;

[0091] When it is necessary to unfold all the shelf components, force can be applied to the third shelf component 500 so that the third shelf component 500 slides along the support frame 200. During the sliding process, the second shelf component 400 is linked and the second shelf component 400 is driven to slide at the same time, so that the effect of simultaneously opening the second shelf component 400 and the third shelf component 500 is achieved through the action of the third shelf component 500.

[0092] After the third shelf component 500 is unfolded, the second shelf component 400 is also unfolded synchronously. At this time, the first shelf component 300, the second shelf component 400 and the third shelf component 500 are arranged in parallel in sequence and the top surfaces are flush with each other. At this time, the shelf assembly is in a fully unfolded state, and its unfolded area is large, which can be used to place a large number of items.

[0093] By improving the structure of the shelf assembly, the shelf assembly can have three different usage states when in use, namely a fully expanded state, a partially folded state and a fully folded state. When in use, the user can slide the third shelf component 500 or the second shelf component 400 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.

[0094] In some embodiments of the present application, a first sliding portion 410 is formed on the second shelf member 400;

[0095] The first sliding portion 410 is a first sliding protrusion formed on the second shelf member 400;

[0096] The support frame 200 is provided with a sliding track 210 for the first sliding part 410 to slide. The sliding track 210 is formed by a sliding track 210 rib integrally formed with the support frame 200. When the second shelf component 400 slides, it can slide along the sliding track 210 through the first sliding protrusion above it.

[0097] The setting of the sliding track 210 can ensure that the second shelf component 400 can slide along the set path when sliding, ensuring that it can be smoothly extended and unfolded and retracted and folded into place.

[0098] In some embodiments of the present application, the sliding rail 210 includes a first sliding section 211, including a straight sliding portion 2111, which can at least position and support the second shelf component 400 when the second shelf component 400 is in the storage state.

[0099] The straight sliding portion 2111 is a straight section, and the top surface is a plane.

[0100] When the first sliding part 410 on the second shelf component 400 slides, it can slide along the straight sliding part 2111. When the second shelf component 400 is in the storage state, the first sliding part 410 above it is located in the straight section and can be effectively supported to prevent it from tilting and sliding.

[0101] The second sliding section 212 is arranged to be inclined upward and smoothly connected to the first sliding section 211 .

[0102] The second sliding section 212 is arranged to tilt upwards, which can ensure that the second shelf component 400 can be extended and unfolded relative to the first shelf component 300 by sliding upwards tilted.

[0103] When the second shelf component 400 slides along the sliding track 210 through the first sliding portion 410, if the second shelf component 400 extends beyond the center position of the sliding track 210, it may tip over due to unstable center of gravity.

[0104] In addition, the second shelf component 400 is pulled to slide by the third shelf component 500 during the sliding process. If it overturns, it will collide with the third shelf component 500, causing the stability of the entire shelf structure to deteriorate and easily be damaged due to the shelves colliding with each other.

[0105] To avoid the above problem, in some embodiments of the present application, a second sliding portion 420 is formed on the second shelf component 400. The second sliding portion 420 is arranged at the front end of the second shelf component 400 and is a second sliding protrusion.

[0106] In some embodiments, the first sliding portion 410 is disposed at a rear end position of the second shelf member 400 , and is arranged opposite to the first sliding portion 410 .

[0107] The guide support slideway 220 correspondingly formed on the support frame 200 is arranged to be inclined upwards and is used to constitute a slideway of the second sliding part 420, which is connected to the sliding track 210;

[0108] During sliding, the second sliding part 420 at the front end can slide along the guide support slide 220, and the guide support slide 220 can support and guide the entire second shelf component 400 to ensure that the second shelf component 400 will not become unstable and tip over during the sliding process.

[0109] The positioning protrusion 230 is formed at the connection between the sliding track 210 and the guide support slideway 220 . The positioning protrusion 230 is integrally injection-molded with the sliding track 210 and the guide support slideway 220 .

[0110] An arc-shaped guide surface is formed on one side of the positioning protrusion 230 to facilitate the first sliding portion 410 to slide to its top position.

[0111] A first clamping portion 221 is formed at the end of the guide support slideway 220;

[0112] In some embodiments, the first clamping portion 221 is a first clamping opening formed at the end of the guide support slide 220 .

[0113] When the second shelf component 400 slides and unfolds, the first sliding part 410 slides along the sliding track 210, and the second sliding part 420 slides along the guide support slideway 220;

[0114] Since the guide support slide 220 is provided, the second sliding part 420 at the front end of the second shelf component 400 can slide along the guide support slide 220, and the first sliding part 410 can slide along the sliding track 210, ensuring stability during the sliding process.

[0115] When the second shelf component 400 is unfolded into place, the first sliding portion 410 is positioned and supported against the positioning protrusion 230 , and the second sliding portion 420 is clamped and fixed in the first clamping portion 221 .

[0116] In order to ensure the stability of the second shelf component 400 when it is unfolded, the first sliding portion 410 at one end thereof is supported and positioned by the positioning protrusion 230 , and the second sliding portion 420 is clamped and fixed by the first clamping portion 221 .

[0117] In some embodiments of the present application, the guide support slide 220 includes an inclined support section 222 and a straight support section 223 connected to the inclined support section 222, the top surface of the straight support section 223 is a plane, and the first clamping portion 221 is formed on the straight support section 223. When the second sliding portion 420 slides to the straight support section 223, it is clamped into the first clamping portion 221 through the second sliding portion 420 and the bottom surface of the second shelf component 400 is firmly positioned by abutting against the straight support section 223 to ensure that it will not shake during use.

[0118] In some embodiments of the present application, in order to enable the third shelf component 500 to be linked with the second shelf component 400 when sliding and unfolding, a mutually cooperating linkage structure is provided between the third shelf component 500 and the second shelf component 400.

[0119] In some embodiments, the linkage structure includes a hook portion 510 disposed at one end of the third shelf component 500 close to the second shelf component 400;

[0120] An extension portion 430 extending downward from the second shelf member 400 is provided at one end of the second shelf member 400 close to the third shelf member 500;

[0121] When the third shelf component 500 is slidably unfolded, it can be clamped on the extension portion 430 through the hook portion 510 to drive the second shelf component 400 to slide and unfold.

[0122] When the third shelf component 500 is slidably stored, the hook portion 510 above it will automatically separate from the extension portion 430 during the sliding process, and will not hinder the sliding storage of the second shelf component 400.

[0123] In some embodiments of the present application, the hook portion 510 includes a transverse main body portion, which is arranged transversely; the transverse main body portion is a transverse main rib, which is arranged transversely;

[0124] and a vertical clamping portion, arranged vertically and connected to the end of the horizontal main body portion;

[0125] A first clamping arm is formed on the vertical clamping portion;

[0126] The vertical clamping portion is a vertical clamping rib, which includes a first clamping arm arranged in a folded manner;

[0127] A second clamping arm is formed on the extension portion 430 . When the third shelf component 500 slides, the first clamping arm above it abuts against the second clamping arm to drive the second shelf component 400 to slide.

[0128] In some embodiments of the present application, the second shelf component 400 includes: a second shelf frame 441 and a second shelf glass plate 442 embedded in the second shelf frame 441;

[0129] The second shelf frame 441 includes a second frame body 4411 and a second frame connecting portion 4412 extending from one side of the second frame body 4411 , and the first sliding portion 410 , the second sliding portion 420 and the extending portion 430 are formed on the second frame connecting portion 4412 .

[0130] In some embodiments, the second shelf connection portion is a second shelf connection flange, which is integrally injection molded with the second frame body 4411 .

[0131] The first sliding portion 410 , the second sliding portion 420 and the extending portion 430 are all formed by extending downward from the second-layer frame connecting flange, and are integrally injection-molded with the second-layer frame connecting flange.

[0132] In some embodiments of the present application, a sliding positioning track 240 is further formed on the support frame 200 , and the sliding positioning track 240 is used to constitute a slideway of the third shelf component 500 .

[0133] The sliding positioning track 240 is arranged upwardly tilted, and extends from the rear end of the support frame 200 to the front end of the support frame 200. The sliding positioning track 240 is arranged upwardly tilted, which can ensure that the third shelf component 500 can slide upwardly and extend and slide downwardly when sliding along the sliding positioning track 240.

[0134] The sliding positioning rail 240 extends from the rear end of the support frame 200 to the front end of the support frame 200, which ensures that the third shelf component 500 can slide from the rear end to the front end or from the front end to the rear end along the support frame 200 alone.

[0135] In some embodiments of the present application, a first sliding limit portion 250 and a second sliding limit portion 270 are formed at both ends of the sliding positioning rail 240 .

[0136] The first sliding limiter 250 and the second sliding limiter 270 can be used to limit the sliding travel of the sliding third shelf component 500 to ensure that it does not fall out of the support frame 200.

[0137] In some embodiments, a second clamping portion 260 located at the front end is further provided at the end of the sliding positioning rail 240 , and the second clamping portion 260 is a second clamping groove.

[0138] In some embodiments of the present application, the third layer frame component 500 includes: a third layer frame body 520, a third layer frame connecting portion 530 is formed on one side of the third layer frame body 520, and the second layer frame connecting portion is a third layer frame connecting flange, which is integrally injection molded with the third layer frame body 520.

[0139] The third shelf connection portion 530 is formed with:

[0140] The sliding support portion 540 is formed by extending downward from the third shelf connecting portion 530, supporting the third shelf component 500 when it slides, and can cooperate with the first sliding limit portion 250 to limit the sliding of the third shelf component 500;

[0141] When the third shelf component 500 slides, the sliding support part 540 above it can be arranged vertically and slide along the sliding positioning rail 240 to support the third shelf component 500. After the third shelf component 500 is slid and stored in place, the sliding support part 540 also supports it by resting on the sliding positioning rail 240 to prevent it from tilting.

[0142] In some embodiments of the present application, the sliding support portion 540 is a sliding support rib, and its corresponding outer diameter gradually increases from top to bottom. The sliding support rib is arranged to have an outer diameter that increases as it approaches the bottom, which can ensure the stability and reliability of its support.

[0143] The sliding support ribs can be either triangular support ribs or conical support ribs.

[0144] In some embodiments of the present application, the first sliding limit portion 250 is arranged at the front end position of the sliding positioning rail 240, which includes a first inclined segment, a second inclined segment and a third inclined segment that are arranged upwardly inclined and connected in sequence, a straight line segment is provided at the end of the third inclined segment, and the second clamping portion 260 is arranged on the straight line segment.

[0145] When the third shelf component 500 slides along the sliding positioning rail 240 until the sliding support portion 540 abuts against the first inclined section, it is blocked and limited and cannot continue to slide.

[0146] The third sliding part 550 is connected to the sliding support part 540 and is slidably disposed on the sliding positioning rail 240 . The third sliding part 550 and the sliding support part 540 can be integrally injection-molded and slide relative to the sliding positioning rail 240 .

[0147] A limiting portion 551 is formed on the third sliding portion 550 for cooperating with the second sliding limiting portion 270 to limit the sliding of the third shelf component 500. The limiting portion 551 is a limiting protrusion formed at the end of the third sliding portion 550.

[0148] In some embodiments, the second sliding limit portion 270 is arranged at the rear end position of the sliding positioning rail 240, which is arranged to be inclined downward, and includes a second sliding straight section and a second sliding inclined section. When the third shelf component 500 slides to the position where the limit portion 551 abuts against the second sliding inclined section, it is limited by the second sliding inclined section so that it cannot continue to slide backward.

[0149] In some embodiments, a positioning portion 560 is further formed on the third shelf connecting portion 530 for being clamped in the second clamping portion 260 when the third shelf component 500 is slid and deployed into place.

[0150] The positioning portion 560 is a positioning protrusion, which is arranged at the front end of the third shelf connecting portion 530. After the third shelf component 500 slides into place, it can be clamped into the second clamping portion 260 to achieve positioning and fixation.

[0151] In some embodiments of the present application, the sliding positioning rail 240 includes a sliding rail body 241;

[0152] and a support slideway 242 formed on one side of the sliding track body 241;

[0153] The support slide 242 is a support slide groove 552 opened along the length direction of the sliding track 210 body;

[0154] A sliding groove 552 is formed in the third sliding portion 550 , and the sliding groove 552 is clamped on the sliding rail body 241 and slides along the sliding rail body 241 ;

[0155] And the folding portion 553 formed on the side of the sliding groove 552 is clamped in the supporting slide 242 and slides relative to the supporting slide 242.

[0156] When the third sliding part 550 slides along the sliding positioning rail 240, it can slide along the sliding rail 210 body through the slide groove, and at the same time, slide along the supporting sliding groove 552 through the folding part 553. The double-layer slide structure can ensure the stability of the entire third shelf component 500 during the sliding process, and also prevent the third shelf component 500 from falling off relative to the sliding positioning rail 240 during the sliding process.

[0157] In some embodiments of the present application, the shelf assembly further includes:

[0158] The fourth shelf component is slidably connected to the support frame 200. When the third shelf component 500 is slidably unfolded, the fourth shelf component can be driven by the second shelf component 400 to unfold;

[0159] When it is in the storage state, it is arranged between the first shelf component 300 and the second shelf component 400;

[0160] When it is in the unfolded state, it is located between the first shelf member 300 and the second shelf member 400 and is flush with the first shelf member 300 and the second shelf member 400.

[0161] In order to increase the folding states of the shelf assembly so that it can have three folding states, a fourth shelf component can be arranged on the first shelf component 300 and the second shelf component 400 accordingly.

[0162] Correspondingly, a fourth shelf slide is provided on the support frame 200, and the fourth shelf slide is located above the first shelf component 300. When the fourth shelf component is driven to unfold, it can slide along the fourth shelf to extend.

[0163] In some embodiments of the present application, in order to achieve the linkage between the fourth shelf component and the second shelf component 400, a linkage structure can be set between the second shelf component 400 and the fourth shelf component, and the structural features of the linkage structure are the same as the linkage structure of the third shelf component 500 and the second shelf component 400.

[0164] When the second shelf component 400 is driven to slide by the third shelf component 500, the hook portion on the second shelf component 400 will be stuck on the extension portion of the fourth shelf component, thereby driving the fourth shelf component to be pulled and slid to achieve expansion.

[0165] By adding the fourth shelf component, the shelf assembly can have three folding states: the third shelf component 500 is slid and stored to the position below the first shelf component 300, and the first shelf component 300, the fourth shelf component, and the second shelf component 400 are arranged side by side and unfolded;

[0166] Alternatively, the third shelf component 500 and the second shelf component 400 are both folded and stored below the first shelf component 300, so that the fourth shelf component and the first shelf component 300 are arranged side by side and unfolded;

[0167] Alternatively, the third shelf component 500, the second shelf component 400 and the fourth shelf component are all slid along the support frame 200 to be stored under the first shelf component 300, so that the first shelf component 300 is used to place items.

[0168] When in the unfolded state, the third shelf component 500 is pulled to drive the second shelf component 400 to slide, and the second shelf component 400 drives the fourth shelf component to slide, and finally the first shelf component 300, the fourth shelf component, the second shelf component 400 and the third shelf component 500 are unfolded side by side with the top surfaces flush.

[0169] In some embodiments of the present application, a plurality of the fourth shelf components are provided, and the plurality of fourth shelf components are sequentially arranged between the first shelf component 300 and the second shelf component 400. Each fourth shelf component is slidably connected to the support frame 200, and a mutually cooperating linkage structure is provided between adjacent fourth shelf components. The structure of the linkage structure is the same as the linkage structure between the fourth shelf component and the second shelf component 400, and is not elaborated here.

[0170] By providing a plurality of fourth shelf components, in cooperation with the second shelf component 400 and the third shelf component 500, the entire shelf assembly can have more different folding use states when in use, thereby meeting the user's needs for different folding use states when in use.
