Description

Technical Field

[0001] This application relates to the field of electrical manufacturing technology, and in particular to a shelf assembly and refrigeration equipment. Background Technology

[0002] Refrigerator doors are usually equipped with bottle holders to make full use of the interior space, especially the door space, allowing users to store beverage bottles, condiment bottles, wine bottles, and other items more effectively and avoid wasting space. However, in actual use, it is often found that the size of the bottle holder does not match the beverage bottles, wine bottles, etc. When the door is opened and closed, the bottles are prone to shaking, causing them to tip over or slip, creating a safety hazard. Utility Model Content

[0003] Based on this, embodiments of this application provide a storage rack assembly and a refrigeration device.

[0004] In a first aspect, embodiments of this application provide a storage rack assembly, including a first storage rack and at least one set of elastic components, wherein the first storage rack includes at least one storage tube, and the storage tube is provided with a first opening;

[0005] In the initial state, at least a portion of the elastic component enters the inner side of the storage tube through the first opening. When an item is placed in the storage tube, the item compresses the elastic component, causing at least a portion of the elastic component to move away from the item. When the movement stops, the elastic component abuts against the item. At this time, elastic potential energy is stored inside the elastic component. When the item is removed from the storage tube, the elastic component restores its initial shape and returns to its initial position.

[0006] In some embodiments, the elastic component includes a rotating member and a first elastic member, the rotating member includes a rotating body rotatably connected to the cylinder, and at least a portion of the rotating body passes through the first opening and enters the inside of the storage cylinder;

[0007] When an item is placed in the storage tube, the item presses against the rotating member to make it rotate. During the rotation, the rotating member applies a force to the first elastic member to accumulate elastic potential energy. When the item is removed from the storage tube, the first elastic member returns to its initial state and drives the rotating member to return to its original position.

[0008] In some embodiments, the storage tube includes a tube body, a first side portion, and a first support shaft. The first side portion and the first support shaft are both disposed on the outside of the tube body. The first side portion is connected to the tube body, and the first support shaft is connected to the first side portion. Furthermore, the first support shaft and the tube body are spaced apart.

[0009] The first elastic element includes a first spiral part, a first torsion arm, and a second torsion arm. The first torsion arm and the second torsion arm are respectively connected to both ends of the first spiral part. The first torsion arm and the second torsion arm are respectively located on opposite sides of the first spiral part. The first spiral part is sleeved on the first support shaft. In the direction perpendicular to the first spiral part, the length of the second torsion arm is greater than the distance between the first spiral part and the cylinder.

[0010] The rotating component further includes a first pushing part connected to the rotating body. The first pushing part is disposed on the outside of the cylinder and is located between the first torsion arm and the cylinder.

[0011] When an item is placed inside the storage tube, the item presses against the rotating member, causing it to rotate. The first pushing part moves away from the tube and pushes the first torsion arm away from the tube. The second torsion arm moves towards the tube and eventually abuts against the outer surface of the tube.

[0012] In some embodiments, the storage tube further includes a second side portion and a second support shaft, both the second side portion and the second support shaft being disposed on the outside of the tube body, the second side portion being connected to the tube body, the second support shaft being connected to the second side portion, and the second support shaft being spaced apart from the tube body;

[0013] The elastic component further includes a second elastic element, which includes a second spiral portion, a third torsion arm, and a fourth torsion arm. The third torsion arm and the fourth torsion arm are respectively connected to both ends of the second spiral portion, and the third torsion arm and the fourth torsion arm are respectively located on opposite sides of the second spiral portion. The second spiral portion is sleeved on the second support shaft, and the length of the fourth torsion arm in the direction perpendicular to the second spiral portion is greater than the distance between the second spiral portion and the cylinder.

[0014] The rotating component further includes a second pushing part connected to the rotating body. The second pushing part is disposed on the outside of the cylinder. The first pushing part and the second pushing part are respectively located on opposite sides of the rotating body. The second pushing part is located between the third torsion arm and the cylinder.

[0015] In some embodiments, the centerlines of the first support shaft and the second support shaft coincide; and / or,

[0016] The first and second pushing parts are symmetrically arranged along the centerline of the rotating body; and / or,

[0017] The storage tube also includes a first rotating shaft and a second rotating shaft. The first rotating shaft is connected to the first side, and the second rotating shaft is connected to the second side. The center lines of the first rotating shaft and the second rotating shaft coincide.

[0018] The first rotating shaft and the second rotating shaft are located on opposite sides of the rotating body. The opposite sides of the rotating body are respectively provided with a first recess and a second recess. One end of the first rotating shaft enters the first recess, and one end of the second rotating shaft enters the second recess.

[0019] In some embodiments, in the direction from the opening to the bottom of the cylinder, the first rotating shaft and the second rotating shaft are disposed close to the opening, and the first supporting shaft and the second supporting shaft are disposed close to the bottom of the cylinder;

[0020] When the rotating component is in its initial state, the first pushing part is located on the side of the first rotating shaft facing the bottom of the cylinder, and the second pushing part is located on the side of the second rotating shaft facing the bottom of the cylinder.

[0021] In some embodiments, the rotating body has a first surface on the side facing the center of the cylinder, and the distance between the points on the first surface and the inner wall of the cylinder gradually increases in the direction from the cylinder opening to the cylinder bottom.

[0022] In some embodiments, the first shelf further includes a connecting portion, which is connected to the opening end of the storage tube;

[0023] The first shelf also includes a frame, the storage tube and the elastic component are both disposed inside the frame, and the frame is connected to the connecting part.

[0024] In some embodiments, the first shelf further includes a mounting part, which is disposed on the outside of the frame and connected to the frame;

[0025] The shelf assembly further includes a second shelf, the first shelf is mounted on the second shelf via the mounting part, and the shelf tube is disposed in the inner cavity of the second shelf.

[0026] Secondly, embodiments of this application provide a refrigeration device, including the shelf assembly described above.

[0027] The storage rack assembly provided in this application embodiment has a first opening on the storage tube, through which at least a portion of the elastic component passes into the inner side of the storage tube. When an item is placed inside the storage tube, the item compresses the elastic component, causing at least a portion of the elastic component to move away from the item. When the movement stops, the elastic component abuts against the item. At this time, the elastic component applies a counterforce to the item, thus fixing the item in the storage tube. When this storage rack assembly is installed on the refrigerator door, it can prevent bottles from shaking during the opening and closing of the door, thereby improving the user experience. Since the elastic component stores elastic potential energy, when an item is removed from the storage tube, the elastic potential energy of the elastic component is converted into kinetic energy, causing the elastic component to return to its initial shape and position, thus facilitating subsequent use. Because the elastic component has good cushioning performance, the storage rack assembly provided in this application embodiment can be used to fix items of various sizes.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0046] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a shelf assembly 100, including a first shelf 21 and at least one set of elastic components 40. The first shelf 21 includes at least one storage tube 211, and the storage tube 211 is provided with a first opening 39.

[0047] In the initial state, at least a portion of the elastic component 40 passes through the first opening 39 and enters the inner side of the storage tube 211. When an item is placed in the storage tube 211, the item compresses the elastic component 40, causing at least a portion of the elastic component 40 to move away from the item. When the movement stops, the elastic component 40 abuts against the item. At this time, the elastic component 40 stores elastic potential energy. When the item is removed from the storage tube 211, the elastic component 40 restores its initial shape and returns to its initial position.

[0048] The storage rack assembly 100 provided in this application embodiment has a first opening 39 on the storage tube 211, allowing at least a portion of the elastic component 40 to pass through the first opening 39 and enter the inside of the storage tube 211. When an item is placed inside the storage tube 211, the item compresses the elastic component 40, causing at least a portion of the elastic component 40 to move away from the item. When the movement stops, the elastic component 40 abuts against the item. At this time, because the elastic component 40 applies a counterforce to the item, the item is fixed in the storage tube 211. When installed on the refrigerator door, the elastic component 100 can prevent bottles from shaking during the opening and closing process, thereby improving the user experience. Since the elastic component 40 stores elastic potential energy, when an item is taken out of the storage tube 211, the elastic potential energy of the elastic component 40 will be converted into kinetic energy, causing the elastic component 40 to return to its initial shape and position, thus facilitating subsequent use. Since the elastic component 40 has good cushioning performance, the storage rack component 100 provided in this application embodiment can be used to fix items of various sizes.

[0049] Please see Figure 3 The storage tube 211 may be provided with a plurality of first openings 39, which may be arranged at intervals along the circumference of the storage tube 211. The storage rack assembly 100 may include a plurality of elastic components 40, which are respectively arranged corresponding to the plurality of first openings 39.

[0050] In the embodiments of this application, "multiple" refers to two or more, such as three, four, five, six, etc., and "multiple groups" refers to two or more groups, such as three, four, five, six, etc.

[0051] Please see Figure 5 , Figure 6 and Figure 9 The elastic component 40 includes a rotating member 50 and a first elastic member 60. The rotating member 50 includes a rotating body 51, which is rotatably connected to the cylinder 30. At least a portion of the rotating body 51 passes through the first opening 39 and enters the inside of the storage cylinder 211.

[0052] When an item is placed in the storage tube 211, the item presses against the rotating member 50 to make it rotate. During the rotation, the rotating member 50 applies a force to the first elastic member 60 to accumulate elastic potential energy. When the item is removed from the storage tube 211, the first elastic member 60 returns to its initial state and drives the rotating member 50 to return to its original position.

[0053] It is understandable that when an item is placed in the storage tube 211, the item moves from top to bottom, which will exert a downward and outward force on the rotating body 51, thereby driving the rotating body 51 to rotate in a counterclockwise direction. At this time, the distance between the part of the rotating body 51 that enters the inner side of the tube 30 and the item will change continuously during the rotation, thereby achieving the effect that part of the rotating body 51 moves away from the item.

[0054] Please see Figure 7 and Figure 8 The storage tube 211 includes a tube body 30, a first side portion 32, and a first support shaft 34. The first side portion 32 and the first support shaft 34 are both disposed on the outside of the tube body 30. The first side portion 32 is connected to the tube body 30, and the first support shaft 34 is connected to the first side portion 32. Furthermore, the first support shaft 34 and the tube body 30 are kept at a distance.

[0055] Please see Figure 9 The first elastic element 60 includes a first spiral portion 61, a first torsion arm 62, and a second torsion arm 63. The first torsion arm 62 and the second torsion arm 63 are respectively connected to both ends of the first spiral portion 61. The first torsion arm 62 and the second torsion arm 63 are respectively located on opposite sides of the first spiral portion 61. The first spiral portion 61 is sleeved on the first support shaft 34. In the direction perpendicular to the first spiral portion 61, the length of the second torsion arm 63 is greater than the distance between the first spiral portion 61 and the cylinder 30.

[0056] It should be noted that the length of the second torsion arm 63 in the direction perpendicular to the first spiral part 61 refers to the distance between the point on the second torsion arm 63 that is farthest from the first spiral part 61 and the first spiral part 61.

[0057] Please see Figure 5 and Figure 6 The rotating component 50 further includes a first pushing part 52 connected to the rotating body 51. The first pushing part 52 is disposed on the outside of the cylinder 30 and is located between the first torsion arm 62 and the cylinder 30.

[0058] When an item is placed in the storage tube 211, the item presses against the rotating member 50 to make it rotate. The first pushing part 52 moves away from the tube body 30 and pushes the first torsion arm 62 away from the tube body 30. The second torsion arm 63 moves towards the tube body 30 and finally abuts against the outer surface of the tube body 30.

[0059] For example, the first elastic element 60 is a torsion spring.

[0060] Understandably, when the first pushing part 52 pushes the first torsion arm 62 to move outward, since the first torsion arm 62 and the second torsion arm 63 are respectively located on opposite sides of the first spiral part 61, during the rotation of the rotating part 50, when the first torsion arm 62 rotates outward, the second torsion arm 63 will rotate inward and abut against the cylinder 30. Since the length of the second torsion arm 63 is greater than the distance between the first spiral part 61 and the cylinder 30, the second torsion arm 63 cannot continue to rotate at this time. When the first torsion arm 62 continues to rotate, the first elastic member 60 deforms and accumulates elastic potential energy.

[0061] Please see Figure 7 and Figure 8 The storage tube 211 also includes a second side portion 33 and a second support shaft 35. The second side portion 33 and the second support shaft 35 are both disposed on the outside of the tube body 30. The second side portion 33 is connected to the tube body 30, and the second support shaft 35 is connected to the second side portion 33. Furthermore, the second support shaft 35 and the tube body 30 are kept at a distance.

[0062] Please see Figure 9 The elastic component 40 further includes a second elastic element 70, which includes a second spiral portion 71, a third torsion arm 72, and a fourth torsion arm 73. The third torsion arm 72 and the fourth torsion arm 73 are respectively connected to both ends of the second spiral portion 71, and the third torsion arm 72 and the fourth torsion arm 73 are respectively located on opposite sides of the second spiral portion 71. The second spiral portion 71 is sleeved on the second support shaft 35. In the direction perpendicular to the second spiral portion 71, the length of the fourth torsion arm 73 is greater than the distance between the second spiral portion 71 and the cylinder 30.

[0063] It should be noted that the length of the fourth torsion arm 73 in the direction perpendicular to the second spiral part 71 refers to the distance between the point on the fourth torsion arm 73 that is farthest from the second spiral part 71 and the second spiral part 71.

[0064] Please see Figure 5 and Figure 6 The rotating component 50 further includes a second pushing part 53 connected to the rotating body 51. The second pushing part 53 is disposed on the outside of the cylinder 30. The first pushing part 52 and the second pushing part 53 are respectively located on opposite sides of the rotating body 51. Furthermore, the second pushing part 53 is located between the third torsion arm 72 and the cylinder 30.

[0065] For example, the second elastic element 70 is a torsion spring.

[0066] It is understandable that by setting the second elastic element 70 and the second pushing part 53, the first pushing part 52 and the second pushing part 53 are located on opposite sides of the rotating body 51, and the first elastic element 60 and the second elastic element 70 are located on opposite sides of the rotating body 51, so that the rotating part 50 can maintain balance on both sides during rotation, thereby making the rotation of the rotating part 50 more stable.

[0067] Please see Figure 7 and Figure 8 The center lines of the first support shaft 34 and the second support shaft 35 coincide.

[0068] Please see Figure 10 The first pushing part 52 and the second pushing part 53 are symmetrically arranged along the center line of the rotating body 51.

[0069] For example, both the first pushing part 52 and the second pushing part 53 are rod-shaped.

[0070] Please see Figure 7 and Figure 8 The storage tube 211 also includes a first rotating shaft 36 and a second rotating shaft 37. The first rotating shaft 36 is connected to the first side portion 32, and the second rotating shaft 37 is connected to the second side portion 33. The center lines of the first rotating shaft 36 and the second rotating shaft 37 coincide.

[0071] Please see Figure 7 , Figure 8 and Figure 10 The first rotating shaft 36 and the second rotating shaft 37 are located on opposite sides of the rotating body 51, and the opposite sides of the rotating body 51 are respectively provided with a first recess 511 and a second recess. One end of the first rotating shaft 36 enters the first recess 511, and one end of the second rotating shaft 37 enters the second recess.

[0072] Please see Figure 10 For example, both the first recess 511 and the second recess are grooves.

[0073] Please see Figure 7 and Figure 8 The first rotating shaft 36 and the first supporting shaft 34 are located on the same side of the rotating body 51, and the second rotating shaft 37 and the second supporting shaft 35 are located on the same side of the rotating body 51.

[0074] Please see Figure 2 , Figure 5 and Figure 6In the direction from the opening 31 of the cylinder 30 to the bottom 38, the first rotating shaft 36 and the second rotating shaft 37 are disposed near the opening 31, and the first support shaft 34 and the second support shaft 35 are disposed near the bottom 38. When the rotating member 50 is in the initial state, the first pushing part 52 is disposed on the side of the first rotating shaft 36 facing the bottom 38, and the second pushing part 53 is disposed on the side of the second rotating shaft 37 facing the bottom 38.

[0075] It is understandable that the initial state of the rotating component 50 refers to the state of the rotating component 50 when no items are placed inside the cylinder 30.

[0076] Please see Figure 10 The rotating body 51 has a first surface S513 on the side facing the center of the cylinder 30. The distance between the position on the first surface S513 and the inner wall of the cylinder 30 gradually increases in the direction from the cylinder opening 31 to the cylinder bottom 38.

[0077] Please see Figure 10 For example, the direction from the opening 31 of the cylinder 30 to the bottom 38 of the cylinder is defined as the first direction, and the angle between the first surface S513 and the first direction is an acute angle.

[0078] It is understandable that by setting the distance between the point on the first surface S513 in the direction from the opening 31 to the bottom 38 of the cylinder 30 and the inner wall of the cylinder 30 to gradually increase, that is, the thickness of the part of the rotating body 51 that enters the inner side of the cylinder 30 in the direction from the opening 31 to the bottom 38 of the cylinder 30 to gradually increase, that is, at this time, the first surface S513 is an inclined surface. This structural design is beneficial to make the movement of items in the direction from the opening 31 to the bottom 38 of the cylinder 30 smoother when items are placed in the cylinder 30, thereby improving the user experience.

[0079] Please see Figure 2 and Figure 3 The first shelf 21 also includes a connecting part 212, which is connected to the opening 31 end of the storage tube 211.

[0080] Please see Figure 2 and Figure 3 The first shelf 21 also includes a frame 213, the storage tube 211 and the elastic component 40 are both disposed on the inner side of the frame 213, and the frame 213 is connected to the connecting part 212.

[0081] For example, the first shelf 21 includes a plurality of storage tubes 211, and the opening 31 of the plurality of storage tubes 211 are all connected to the connecting part 212.

[0082] Please see Figure 1 , Figure 2 and Figure 3 The first shelf 21 further includes a mounting part 214, which is disposed on the outside of the frame 213 and connected to the frame 213; the shelf assembly 100 further includes a second shelf 22, the first shelf 21 is mounted on the second shelf 22 through the mounting part 214, and the shelf tube 211 is disposed in the inner cavity of the second shelf 22.

[0083] For example, the mounting part 214 is detachably connected to the second shelf 22, so that the first shelf 21 can be removed when it is not needed, and the first shelf 21 can be repaired or replaced.

[0084] Understandably, the second shelf 22 can be fixed to the refrigerator door.

[0085] Please see Figure 2 and Figure 3 For example, the mounting part 214 includes a horizontal part 201 and a vertical part 202 connected together. The two ends of the horizontal part 201 are connected to the frame 213 and the vertical part 202 respectively. There is a gap between the vertical part 202 and the frame 213. The mounting part 214 is engaged with the side wall of the second shelf 22 through the gap.

[0086] This application also provides a refrigeration device, including the shelf assembly 100 in any of the above embodiments.

[0087] For example, the refrigeration equipment includes a cabinet and a door, the door being rotatably connected to the cabinet, and the shelf assembly 100 being installed on the inside of the door.

[0088] For example, the refrigeration equipment can be a refrigerator, freezer, beverage cooler, wine cooler, freezer box, ice cream machine, ice maker, etc.

Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
