Description
Technical Field
[0001] The present application relates to the technical field of refrigerators, and particularly to a foldable shelf that can be lifted and a refrigerator thereof. Background Art
[0002] With the upgrading of refrigerators, people have put forward higher and higher requirements for the use of the space inside the refrigerator. To increase the convenience of storage in the refrigerator and achieve layered storage of food materials, most existing refrigerators are provided with shelves inside the cabinet. Different items can be placed on the shelves, and the shelves divide the interior of the refrigerator into different spaces, facilitating users to pick up and place items.
[0003] However, the integral shelf can only meet the small adjustment in the height direction. To improve the flexibility of storage, some refrigerators are also provided with foldable shelves. The half-fold function of the foldable shelf can meet the storage of some tall items and improve the user experience of using the refrigerator shelf.
[0004] Most existing foldable shelves are composed of two front and rear half-shelves. When folding, the front shelf is usually moved to the lower part of the rear shelf. Although the folding method of stacking the front and rear shelves improves the storage height of the front half of the shelf, it also makes the front shelf lose its storage function, thus reducing the utilization rate of the storage space. Summary of the Invention
[0005] In order to overcome the above-mentioned technical problems in the prior art, the present application provides a foldable shelf that can be lifted and a refrigerator thereof.
[0006] In a first aspect, a foldable shelf that can be lifted provided by the present application adopts the following technical solutions: A foldable shelf that can be lifted, comprising Two brackets, which are distributed at the same height. Each bracket includes a side plate, a bottom plate fixed to the inner bottom of the side plate, a top plate fixed to the inner top of the side plate, and a support plate fixed to the middle of the inner side of the side plate. The top plate is located at the front end of the side plate and jointly encloses a first chute with the side plate and the bottom plate. The support plate is located at the rear end of the side plate and jointly encloses a second chute with the side plate and the bottom plate. The first chute is communicated with the second chute. The inner side of the side plate above the second chute is set as a receiving cavity; A front partition, located between the two brackets, and both sides of the front partition are slidably arranged between the first chute and the second chute; and A rear partition, located between the two brackets, and a lifting mechanism for driving the rear partition to lift is arranged in the receiving cavity.
[0007] By adopting the above technical solution, when the current partition plate slides into the first chute and the rear partition plate is folded into the accommodating cavity under the drive of the lifting mechanism, the liftable folding shelf is in a flattened state at this time, and both the front partition plate and the rear partition plate can be used for storing items. When the current partition plate slides into the second chute and the rear partition plate is folded into the accommodating cavity under the drive of the lifting mechanism, the liftable folding shelf is in a folded state at this time, and both the front of the front partition plate and the upper part of the rear partition plate can be used for storing items. When the current partition plate slides into the second chute and the rear partition plate rises under the drive of the lifting mechanism, at this time, both the front of the front partition plate, the upper part of the front partition plate, and the upper part of the rear partition plate can be used for storing items, improving the flexibility of the refrigerator storage and the utilization rate of the refrigerator space.
[0008] Furthermore, two sets of the lifting mechanisms are provided, and the two sets of the lifting mechanisms are respectively located on both sides of the rear partition plate. The lifting mechanism includes two cross-set support rods, a rotating shaft for rotatably connecting the two support rods, a mounting plate located above the two support rods, a lower slide rail fixed in the accommodating groove, and an upper slide rail fixed at one end of the mounting plate. Both the upper slide rail and the lower slide rail are located on the same side of the rotating shaft. Sliding grooves are respectively formed through the upper slide rail and the lower slide rail, and a slide rod is slidably arranged in the sliding groove. One ends of the two support rods are respectively rotatably connected to the corresponding slide rod, and the other ends of the two support rods are respectively hinged to the side plate and the mounting plate. A locking structure is arranged in the sliding groove for locking and positioning the slide rod.
[0009] By adopting the above technical solution, when it is necessary to adjust the height of the rear partition plate, only need to drive the two support rods to rotate around the rotating shaft, so that one ends of the two support rods respectively push the slide rod to slide in the corresponding sliding groove, thereby adjusting the height of the rear partition plate and the mounting plate. After the height adjustment of the rear partition plate is completed, the locking structure can be used to lock the slide rod, so that the included angle between the two support rods remains stable. At this time, the rear partition plate is stably supported at a suitable height by the mounting plate.
[0010] Furthermore, the locking structure is set as a card rack fixed on the top wall of the sliding groove of the upper slide rail, and a plurality of tooth grooves for clamping the slide rod are formed at the bottom of the card rack.
[0011] By adopting the above technical solution, when adjusting the height of the rear partition board, the support rod pushes the sliding rod to slide in the sliding groove, and the upper sliding rail is rotatably connected to one end of the support rod through the mounting plate. When it is necessary to lock one end of another support rod, only need to drive the mounting plate to slightly lift upward, so that the sliding rod aligns with a tooth groove on the card rack, and then lower the mounting plate. Under the action of gravity, the mounting plate drives the tooth groove on the card rack to be clamped on the sliding rod, thereby locking one end of the support rod, and further keeping the included angle between the two support rods stable. At this time, the rear partition board is stably supported at an appropriate height by the mounting plate.
[0012] Furthermore, mounting shells for the mounting plate and the upper sliding rail to be inserted together are fixed on both sides of the rear partition board. Flanges are bent at the tops of the mounting plate and the upper sliding rail, and pressing blocks for pressing the flanges are arranged on the inner top wall of the mounting shell.
[0013] By adopting the above technical solution, the rear partition board is connected through the insertion of the mounting shell and the mounting plate. The pressing block presses the flange, making it difficult for the mounting plate to fall off from the mounting shell, and at the same time, it is also difficult for the mounting plate to warp relative to the mounting shell, ensuring a stable connection between the rear partition board and the lifting mechanism.
[0014] Furthermore, clamping posts are protrudingly arranged on the inner bottom wall of the mounting shell, and clamping grooves for the clamping posts to be inserted are opened at the bottom of the mounting plate.
[0015] By adopting the above technical solution, when connecting the mounting plate and the mounting shell, the clamping post is inserted into the clamping groove. Under the combined action of the clamping post and the clamping groove, it is difficult for the mounting plate to move back and forth in the mounting shell, further ensuring a stable connection between the rear partition board and the lifting mechanism.
[0016] Furthermore, when the rear partition board descends and is folded in the accommodating cavity, the edge of the mounting shell fits against the inner side wall of the side board, and the front end of the mounting shell fits against the rear end of the top board.
[0017] By adopting the above technical solution, when the rear partition board descends and is folded in the accommodating cavity, the edge of the mounting shell fits against the inner side wall of the side board, and the front end of the mounting shell fits against the rear end of the top board, eliminating the gap between the top board, the side board and the mounting shell, making the rear partition board and the bracket highly integrated visually when the liftable folding shelf is in the flattened state.
[0018] Furthermore, a plurality of sliders are fixed on both sides of the front partition board. The front partition board is slidably mounted in the first chute and the second chute through the sliders. A yielding groove is formed at the front end of the first chute. The yielding groove communicates with the first chute and forms a stepped portion. A bracket is installed at the rear end of the first chute. When the front partition board needs to be installed in the first chute, only by moving the slider at the front end of the front partition board into the yielding groove, aligning the slider at the rear end of the front partition board with the bracket, and then moving the front partition board backward until the slider at the rear end of the front partition board is placed on the bracket. At this time, the slider at the front end of the front partition board abuts against the stepped portion.
[0019] By adopting the above technical solution, the front partition board is slidably mounted between the two brackets through the sliders. When the front partition board needs to be installed in the first chute, only by moving the slider at the front end of the front partition board into the yielding groove, aligning the slider at the rear end of the front partition board with the bracket, and then moving the front partition board backward until the slider at the rear end of the front partition board is placed on the bracket. At this time, the slider at the front end of the front partition board abuts against the stepped portion. The front partition board abuts against the edge of the top plate, and the front end of the rear partition board received in the accommodation cavity abuts against the rear end of the front partition board. The structure of pushing and placing backward eliminates the gaps between the front partition board and the rear partition board, and between the front partition board and the two side top plates, and has high visual integrity.
[0020] Furthermore, when the front partition board is mounted in the first chute, the edge of the front partition board fits with the edge of the top plate. When the front partition board is located in the second chute, the edge of the front partition board fits with the edge of the support plate.
[0021] By adopting the above technical solution, when the front partition board is mounted in the first chute, the edge of the front partition board fits with the edge of the top plate, making the front partition board and the two brackets have high visual integrity after being horizontally unfolded. When the front partition board is located in the second chute, the edge of the front partition board fits with the edge of the support plate, making the front partition board and the two brackets have high visual integrity after being folded under the rear partition board.
[0022] Furthermore, the stepped portion is formed by a transition of a slope surface.
[0023] By adopting the above technical solution, the setting of the slope surface enables the slider on the front partition board to smoothly slide into the yielding groove along the slope surface during the process of horizontally placing the front partition board, so that the slider at the rear end of the front partition board can quickly rotate to align with the bracket, reducing the difficulty of horizontally unfolding the front partition board to a certain extent and improving the unfolding efficiency of the liftable folding shelf.
[0024] In a second aspect, a refrigerator provided by the present application includes a box body and a liftable folding shelf, and the liftable folding shelf is arranged in the box body.
[0025] By adopting the above technical solution, the front partition in the liftable folding shelf can be folded backward, and the rear partition can be lifted up and down, which improves the flexibility of refrigerator storage and the utilization rate of refrigerator space.
[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. In the liftable folding shelf, the front partition can be folded backward, and the rear partition can be lifted up and down, which improves the flexibility of refrigerator storage and the utilization rate of refrigerator space; 2. The lifting mechanism is modularly assembled with the rear partition through the mounting plate, mounting shell, pressing block and clamping column, which improves the assembly efficiency; 3. In the lifting mechanism, there are multiple tooth grooves on the rack with teeth, so that the rear partition has multiple lifting gears, which is convenient for users to adjust flexibly; 4. When the liftable folding shelf is restored from the folded state to the unfolded state, the horizontal placement of the front partition needs to be completed through a backward pushing action. The structural method of backward pushing placement eliminates the gap between the front partition and the rear partition, and has a high visual integrity. Description of the Drawings

Detailed implementation manners
[0034] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.
[0035] An embodiment of the present application discloses a liftable folding shelf and a refrigerator thereof. Refer to Figure 1 and Figure 2 , the refrigerator includes a box body 24 and a liftable folding shelf. A storage compartment is formed inside the box body 24, and the liftable folding shelf is detachably installed in the storage compartment inside the box body 24.
[0036] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , a liftable folding shelf includes two brackets distributed at the same height and a front partition 9 and a rear partition 10 movably arranged between the two brackets. The two brackets are horizontally installed on the inner walls on both sides of the box body 24, and the rear partition 10 is liftably erected between the two brackets. The front partition 9 can either slide and unfold to be erected in front of the rear partition 10 or slide and fold to be below the rear partition 10, making the storage of the refrigerator equipped with the liftable folding shelf more flexible and improving the utilization rate of the space in the refrigerator at the same time.
[0037] To facilitate the quick installation of the front partition 9 on the bracket, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5, the bracket includes side plates 1 fixedly connected to the same inner side wall, a bottom plate 2 fixed to the inner bottom of the side plates 1, a top plate 3 fixed to the inner top of the side plates 1, and a support plate 4 fixed to the middle part of the inner side of the side plates 1. The top plate 3 is located at the front end of the side plates 1 and together with the side plates 1 and the bottom plate 2 encloses a first chute 5. The support plate 4 is located at the rear end of the side plates 1 and together with the side plates 1 and the bottom plate 2 encloses a second chute 6. The first chute 5 communicates with the second chute 6. The inner side of the side plates 1 above the second chute 6 is provided as a receiving cavity 7. At the same time, a yielding groove 21 is opened at the front end of the first chute 5. The yielding groove 21 is located in the upper middle part of the first chute 5. The yielding groove 21 communicates with the first chute 5 and forms a stepped part 22. A bracket 23 is installed at the rear end of the first chute 5. The bracket 23 is L-shaped, and one end of the bracket 23 is fixed to the top plate 3, so that the notch formed between the bracket 23 and the top plate 3 faces the direction of the yielding groove 21.
[0038] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , a plurality of sliders 20 are fixed on both sides of the front partition 9. In the embodiment of the present application, two sliders 20 on the same side of the front partition 9 are provided. The front partition 9 is stably slidably mounted in the first chute 5 and the second chute 6 on the bracket through the two sliders 20 on both sides. When the foldable shelf that can be lifted needs to be unfolded, the front partition 9 can be first pushed forward and slid between the two brackets, so that the sliders 20 slide out of the second chute 6 and enter the first chute 5, and then the front partition 9 is continuously pushed forward, so that the sliders 20 at the front end of the front partition 9 enter the yielding groove 21 along the stepped part 22. At this time, the sliders 20 at the rear end of the front partition 9 are located in front of the bracket 23. Then the rear end of the front partition 9 is rotated upward so that the sliders 20 at the rear end of the front partition 9 are aligned with the bracket 23. Finally, the front partition 9 is moved backward until the sliders 20 at the rear end of the front partition 9 are placed on the bracket 23. At this time, the sliders 20 at the front end of the front partition 9 abut against the stepped part 22. At the same time, the edges on both sides of the front partition 9 are attached to the edges of the corresponding top plate 3. The front partition 9 is stably horizontally unfolded and erected between the two brackets. When the front partition 9 is folded between the two brackets, the front partition 9 can be moved backward so that the sliders 20 on both sides of the front partition 9 slide into the second chute 6 below the support plate 4. At this time, the edge of the front partition 9 is attached to the edge of the support plate 4.
[0039] Considering that the sliders 20 on the front partition 9 need to enter the yielding groove 21 through the stepped part 22, so referring to Figure 3 , Figure 4 and Figure 5, the stepped portion 22 is formed by a sloped surface transition, and the slider 20 is also set to a U shape, so that when moving the front partition 9, the slider 20 at the front end of the front partition 9 can smoothly pass through the stepped portion 22 and enter the recessed groove 21, prompting the slider 20 at the rear end of the front partition 9 to quickly align with the bracket 23 and be inserted onto the bracket 23.
[0040] To enable the rear partition 10 to be stably elevated and installed between the two brackets, referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , a lifting mechanism 8 for driving the rear partition 10 to lift is provided in the receiving cavity 7 on the bracket. There are two sets of lifting mechanisms 8, and the two sets of lifting mechanisms 8 are respectively located on both sides of the rear partition 10, so that the rear partition 10 can be smoothly lifted and adjusted between the two brackets under the lifting of the two sets of lifting mechanisms 8.
[0041] Considering the convenience of assembling the rear partition 10 and the lifting mechanism 8, referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the lifting mechanism 8 includes two cross-set support rods 81, a rotating shaft 82 for rotatably connecting the two support rods 81, a mounting plate 83 located above the two support rods 81, a lower slide rail 84 fixed in the receiving groove, and an upper slide rail 85 fixed to one end of the mounting plate 83. The side wall of the rear partition 10 is connected to the mounting plate 83. The upper slide rail 85 and the lower slide rail 84 are both located on the same side of the rotating shaft 82. The lower slide rail 84 is located on the side of the receiving groove close to the top plate 3 and is located below the top plate 3. At the same time, to eliminate the gap between the rear partition 10 and the side plate 1 after folding, the lower slide rail 84 is penetrated and embedded on the side plate 1, and sliding grooves 11 are respectively formed through the upper slide rail 85 and the lower slide rail 84. The two support rods 81 are of equal length, and the rotating shaft 82 is located in the middle of the support rod 81. The bottom end of one of the support rods 81 is hinged to the inner side wall of the rear end of the side plate 1, and the other end is rotatably connected to a sliding rod 12, and the sliding rod 12 is slidably installed in the sliding groove 11 of the upper slide rail 85. The top end of the other support rod 81 is hinged to the inner side wall of the end of the mounting plate 83 away from the upper slide rail 85, and the other end is also rotatably connected to a sliding rod 12, and at the same time, the sliding rod 12 is slidably installed in the sliding groove 11 of the lower slide rail 84. When adjusting the height of the rear partition 10, the two support rods 81 can be driven to rotate relative to each other, so that the two sliding rods 12 slide in the upper slide rail 85 and the lower slide rail 84 respectively, thereby realizing a rapid and stable adjustment of the height of the rear partition 10.
[0042] After the height of the rear partition 10 is adjusted, it is necessary to stably lock the rear partition 10 at the appropriate height. For this purpose, referring to Figure 2 , Figure 3 , Figure 4 andFigure 5 Inside the sliding groove 11, a locking structure is provided for locking and positioning the sliding rod 12. For the convenience of quickly unlocking and locking the locking structure, in the embodiment of the present application, the locking structure is arranged in the sliding groove 11 of the upper sliding rail 85. The locking structure is specifically a clamping rack 13 fixed on the inner top wall of the sliding groove 11 of the upper sliding rail 85. Multiple tooth grooves 14 for clamping the sliding rod 12 are formed at the bottom of the clamping rack 13. When adjusting the height of the rear partition 10, the support rod 81 pushes the sliding rod 12 to slide in the sliding groove 11, and the upper sliding rail 85 is rotatably connected to one end of the support rod 81 through the mounting plate 83. When it is necessary to lock one end of another support rod 81, only need to slightly lift the mounting plate 83 upward, so that the sliding rod 12 is aligned with one tooth groove 14 on the clamping rack 13, and then lower the mounting plate 83. Under the action of gravity, the mounting plate 83 drives the tooth groove 14 on the clamping rack 13 to be clamped on the sliding rod 12, so as to lock one end of the support rod 81, and further keep the included angle between the two support rods 81 stable. At this time, the rear partition 10 is stably supported at an appropriate height by the mounting plate 83. When the rear partition 10 descends and is folded into the accommodation cavity 7, the edge of the mounting shell 15 fits with the inner side wall of the side plate 1, the front end of the mounting shell 15 fits with the rear end of the top plate 3, and at the same time the front end of the rear partition 10 fits tightly with the rear end of the front partition 9 after being horizontally unfolded, so that the visually overall integrity of the liftable folding shelf is high after being unfolded.
[0043] To enable the rear partition 10 to be quickly installed and disassembled on the mounting plate 83, referring to Figure 4 and Figure 5 On both sides of the rear partition 10, mounting shells 15 for the mounting plate 83 and the upper sliding rail 85 to be inserted together are fixed. Flanges 16 are bent at the tops of the mounting plate 83 and the upper sliding rail 85. A pressing block 17 for pressing the flange 16 is arranged on the inner top wall of the mounting shell 15. When the rear partition 10 is connected through the insertion of the mounting shell 15 and the mounting plate 83, the pressing block 17 presses the flange 16, so that the mounting plate 83 is not easily detached from the mounting shell 15, and at the same time the mounting plate 83 is not easily warped relative to the mounting shell 15, ensuring a stable connection between the rear partition 10 and the lifting mechanism 8. At the same time, a clamping post 18 protrudes from the inner bottom wall of the mounting shell 15, and a clamping groove 19 for the clamping post 18 to be inserted is formed at the bottom of the mounting plate 83. When connecting the mounting plate 83 and the mounting shell 15, the clamping post 18 is inserted into the clamping groove 19. Under the joint action of the clamping post 18 and the clamping groove 19, the mounting plate 83 is not easily moved back and forth in the mounting shell 15, further ensuring a stable connection between the rear partition 10 and the lifting mechanism 8.
[0044] The implementation principle of a liftable folding shelf and its refrigerator in an embodiment of this application is as follows: During installation, first, the front partition 9 can be slidably mounted between two brackets through the sliders 20 on both sides. Then, drive the front end of the mounting plate 83 to slightly lift upward, so that the sliding rod 12 moves out of the tooth groove 14 of the card rack 13. Next, rotate the two support rods 81 so that the mounting plate 83 is lifted above the receiving cavity 7. Then, respectively snap the two mounting plates 83 into the mounting shells 15 on both sides of the rear partition 10, so that the pressing block 17 presses against the flanging 16 and the card post 18 is inserted into the card slot 19, thereby completing the assembly of the liftable folding shelf. Finally, mount the two brackets at the same height and horizontally on the inner walls on both sides of the box body 24.
[0045] When the liftable folding shelf needs to be horizontally unfolded, first push the front partition 9 to slide forward between the two brackets, so that the slider 20 slides out of the second chute 6 and enters the first chute 5. Then continue to push the front partition 9 forward, so that the slider 20 at the front end of the front partition 9 enters the retraction groove 21 along the stepped portion 22. At this time, the slider 20 at the rear end of the front partition 9 is in front of the bracket 23. Then rotate the rear end of the front partition 9 upward so that the slider 20 at the rear end of the front partition 9 aligns with the bracket 23. Continue to move the front partition 9 backward until the slider 20 at the rear end of the front partition 9 is placed on the bracket 23. At this time, the slider 20 at the front end of the front partition 9 abuts against the stepped portion 22. At the same time, both side edges of the front partition 9 are attached to the edges of the corresponding side top plate 3. The front partition 9 is stably horizontally unfolded and mounted between the two brackets. Finally, drive the two support rods 81 to rotate, so that the mounting plate 83 drives the rear partition 10 to descend to the lowest position in the receiving groove. Then, through the clamping action between the sliding rod 12 and the tooth groove 14, limit the rotation of the support rod 81, so that the rear partition 10 is stably locked between the two brackets. At this time, the rear partition 10 is at the same height as the front partition 9 and abuts against each other. At the same time, the edge of the mounting shell 15 on the rear partition 10 is attached to the inner wall of the side plate 1, and the front end of the mounting shell 15 is attached to the rear end of the top plate 3, so that the liftable folding shelf has a high visual integrity after unfolding.
[0046] When the front partition 9 in the liftable folding shelf needs to be folded under the rear partition 10, first move the front partition 9 forward so that the slider 20 at the rear end of the front partition 9 disengages from the bracket 23. At this time, the slider 20 at the front end of the front partition 9 enters the retraction groove 21. Then rotate the rear end of the front partition 9 downward and move the front partition 9 backward so that the slider 20 at the front end of the front partition 9 moves from the retraction groove 21 to the first chute 5. Continue to move the front partition 9 backward until the sliders 20 at the front and rear ends of the front partition 9 both slide into the second chute 6. At this time, the front partition 9 is folded under the rear partition 10.
[0047] When it is necessary to adjust the height of the rear partition 10, first drive the mounting plate 83 to lift slightly upward so that the sliding rod 12 disengages from the tooth groove 14, and then rotate the two support rods 81. At this time, the two sliding rods 12 slide in the sliding grooves 11 of the upper sliding rail 85 and the lower sliding rail 84 respectively until the mounting plate 83 and the rear partition 10 are adjusted to the appropriate positions. Finally, rotate the mounting plate 83 downward so that the mounting plate 83 drives the tooth groove 14 on the rack 13 to be clamped on the sliding rod 12 under the action of gravity, thereby locking one end of the support rod 81, and further keeping the included angle between the two support rods 81 stable. At this time, the rear partition 10 is stably supported at the appropriate height by the mounting plate 83.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
