Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more particularly to a refrigerator. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, keeping food or other items at a constant temperature. To increase storage space, refrigerator doors are usually equipped with door shelves. These shelves are typically used to store beverages, bottled sauces, and similar items.

[0003] In related technologies, door shelves have limited height, resulting in a high center of gravity when tall bottles of beverages or sauces are placed on them. Upon opening and closing the refrigerator door, items inside the door shelves are prone to tipping over, shaking, colliding, or even falling out of the door due to inertia. This leads to poor stability when storing items inside the door shelves. Utility Model Content

[0004] This application provides a refrigerator that improves the stability of items stored on the door shelves.

[0005] In a first aspect, embodiments of this application provide a refrigerator, which includes:

[0006] The box is constructed to form a storage compartment with an access opening;

[0007] The door is rotatably connected to the box body to close or open the loading / unloading port;

[0008] A door shelf is installed on the side of the door facing the storage room;

[0009] A limiting mechanism is installed on the side of the door facing the storage compartment and located above the door shelf; the limiting mechanism includes:

[0010] A clamping assembly including two clamping arms that enclose a clamping cavity for clamping an item within the door shelf; the two clamping arms are configured to be movable relative to each other;

[0011] A height adjustment assembly, one side of which is mounted on the side of the door facing the storage compartment, and the other side of which is connected to the clamping assembly, is configured to adjust the position of the clamping assembly and the door shelf along the height direction of the door.

[0012] The refrigerator of this embodiment increases storage space by providing a door shelf on the side of the door facing the storage compartment. A limiting mechanism on the same side of the door secures items within the door shelf, fixing their position relative to the shelf and preventing them from tipping over or falling during door opening and closing. This improves the stability of the items and enhances the refrigerator's safety. The limiting mechanism includes a clamping assembly with two clamping arms forming a clamping cavity to hold items within the door shelf. The two clamping arms are designed to move relative to each other, adjusting the distance between them. This allows the clamping cavity to hold and secure items of different sizes, increasing the versatility of the limiting mechanism. Furthermore, a height adjustment assembly adjusts the position of the clamping assembly and the door shelf along the door's height, allowing the clamping assembly to hold items of different heights or at different heights. This not only improves the versatility of the limiting mechanism but also enhances the reliability of its gripping function.

[0013] In some embodiments of this application, the height adjustment component includes:

[0014] A first connector, one end of which is fixedly connected to the clamping assembly;

[0015] The second connector has one end fixedly connected to the side of the door facing the storage compartment. The second connector is hinged to the first connector so that the clamping assembly can rotate relative to the horizontal plane of the door, and the horizontal plane of the door is perpendicular to the height direction of the door.

[0016] In this embodiment, the height adjustment component is fixedly connected to the clamping component by a first connector and connected to the inner liner of the door body by a second connector. The clamping component can be rotated relative to the horizontal plane of the door body by hinged first and second connectors, which can adjust the position of the clamping component and the door shelf along the height direction of the door body.

[0017] In some embodiments of this application, the height adjustment component further includes:

[0018] The rotating shaft passes through the shaft holes of the first connector and the second connector;

[0019] A first adjusting member is threadedly connected to the end of the rotating shaft; the first adjusting member is configured to lock the first connecting member and the second connecting member to restrict relative rotation between the first connecting member and the second connecting member; or, the first adjusting member is configured to unlock the first connecting member and the second connecting member to allow relative rotation between the first connecting member and the second connecting member.

[0020] In this embodiment, the first and second connectors of the height adjustment assembly are hinged by a pivot, and the first adjustment component is threadedly connected to the pivot. Tightening and loosening the first adjustment component locks and unlocks the first and second connectors. The structure is simple and the cost is low; the adjustment operation is simple and convenient.

[0021] In some embodiments of this application, one end of the second connector is provided with a suction cup, which is attached to the side of the door facing the storage room.

[0022] A suction cup is provided at the end of the second connector opposite to the first connector. Utilizing the suction cup's adsorption force, not only is the height adjustment component connected to the door, but the user can also flexibly adjust the position of the limiting mechanism according to actual usage, improving the flexibility of the limiting mechanism's application. Furthermore, there is no need for a fixing structure on the door or drawer, making the limiting mechanism simple in structure and low in cost.

[0023] In some embodiments of this application, one end of the second connector is provided with a first magnetic element, and the side of the door facing the storage room is provided with a second magnetic element, the second magnetic element and the first magnetic element being magnetically attracted to each other.

[0024] This application embodiment uses a first magnetic component and a second magnetic component that attract each other to achieve the connection between the height adjustment component and the door body. This not only allows for flexible adjustment of the position of the limiting mechanism, but also makes the connection of the limiting mechanism stable and reliable, and makes the assembly and disassembly of the limiting mechanism convenient.

[0025] In some embodiments of this application, the height adjustment component includes:

[0026] A first connector, one end of which is fixedly connected to the clamping assembly;

[0027] The second connector has one end fixedly connected to the side of the door facing the storage room, and the second connector is slidably connected to the first connector along the height direction of the door.

[0028] The limiting member is configured to lock the first connector and the second connector, or to unlock the first connector and the second connector so that the first connector and the second connector slide relative to each other.

[0029] In this embodiment, the position of the clamping assembly along the height direction of the door is adjusted by sliding the first connector and the second connector together; and the first connector and the second connector are unlocked or locked by the limiting member, so that the height position of the clamping assembly can be adjusted or fixed.

[0030] In some embodiments of this application, the clamping assembly further includes a mounting base, which is fixedly connected to the height adjustment assembly; at least one of the two clamping arms is slidably mounted on the mounting base.

[0031] The clamping assembly of this application embodiment provides a mounting base for the clamping arms, and at least one of the two clamping arms is slidably mounted on the mounting base so that the two clamping arms can slide relative to each other to adjust the interval between the two clamping arms, so that the clamping cavity can clamp items of different diameters.

[0032] In some embodiments of this application, the clamping assembly further includes:

[0033] Two connecting arms, one end of each of the two connecting arms being rotatably connected to one end of the two clamping arms;

[0034] A second adjusting member is rotatably mounted on the mounting base and located between the two connecting arms; the second adjusting member is rotatably connected to the other end of the two connecting arms.

[0035] When the second adjusting member rotates, it drives the two connecting arms to rotate in opposite directions, so that the two clamping arms slide towards or away from each other.

[0036] In this embodiment, the clamping assembly is provided with a second adjusting member and two connecting arms. The second adjusting member is connected to the clamping arm through the connecting arms. By utilizing the rotational connection between the two ends of the connecting arm and the second adjusting member and the clamping arm, the rotational movement of the second adjusting member is adjusted into the movement of the clamping arm, thereby adjusting the interval between the two clamping arms.

[0038] One of the mounting hole wall and the second adjusting member is provided with a protrusion, and the other is provided with a plurality of recesses, the plurality of recesses being arranged at intervals along the circumference of the second adjusting member; the protrusion and the recesses are engaged.

[0039] The embodiments of this application provide resistance to the rotation between the second adjusting member and the mounting hole through the cooperation of the protrusion and the recess, thereby preventing the second adjusting member from rotating arbitrarily between the two holes and improving the reliability and stability of the limiting mechanism in clamping the item.

[0040] In some embodiments of this application, multiple limiting mechanisms are provided, and the multiple limiting mechanisms are arranged at intervals along the length direction of the door shelf.

[0041] This allows for the positioning of multiple items along the length of the door shelf.

[0042] In some embodiments of this application, multiple limiting mechanisms are arranged at intervals along the height direction of the door body.

[0043] This allows for the restraint and fixation of taller items, improving their stability.

[0044] Secondly, embodiments of this application provide a refrigerator, which includes:

[0045] The box is constructed to form a storage compartment with an access opening;

[0046] A movable component is configured to form a storage cavity; the movable component is movable relative to the housing to open or close the storage cavity;

[0049] A height adjustment assembly, one side of which is mounted on the movable member and the other side of which is connected to the clamping assembly, is configured to adjust the position of the clamping assembly along the height direction of the refrigerator.

[0050] The refrigerator of this embodiment uses a limiting mechanism on a moving component to fix items in the storage cavity. This fixes the position of the items relative to the moving component, preventing them from tipping over during the movement of the moving component, thus improving the stability of the items and ultimately enhancing the refrigerator's safety. The limiting mechanism includes a clamping assembly with two clamping arms forming a clamping cavity to hold the items in the storage cavity. The two clamping arms are designed to move relative to each other, adjusting the distance between them. This allows the clamping cavity to hold and fix items of different sizes, improving the versatility of the limiting mechanism. Furthermore, the limiting mechanism incorporates a height adjustment assembly to adjust the position of the clamping assembly along the height of the door. This allows the clamping assembly to hold items of different heights or at different height positions, improving both the versatility and the reliability of the clamping mechanism.

[0076] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0077] Combination Figure 1 and Figure 2 Some embodiments of this application provide a refrigerator, which includes a cabinet 100, which can be configured to form a storage compartment 101 with an access opening for storing items.

[0078] Multiple storage compartments 101 can be provided to expand storage space. Depending on the storage temperature of the storage compartments 101, they can include at least one refrigerated compartment and at least one frozen compartment. The internal temperature of the refrigerated compartment can be maintained between approximately 0°C and 5°C for storing items in refrigeration mode; the internal temperature of the frozen compartment can be maintained between approximately -30°C and 0°C for storing items in freezing mode.

[0079] In some possible implementations, at least one of the storage chambers 101 may also be configured as a vacuum chamber or a variable temperature chamber, etc., which will not be described in detail in the embodiments of this application.

[0080] For example, two storage compartments 101 can be provided, which can be stacked vertically or arranged side by side horizontally. One of them can be a refrigerator compartment and the other can be a freezer compartment.

[0081] In some embodiments, combined withFigure 1 and Figure 2 The refrigerator body 100 may include a refrigerator liner and a refrigerator shell. The refrigerator liner may be configured to form a storage compartment 101 with a front opening 613. The refrigerator shell may be attached to the outside of the refrigerator liner to form the appearance of a refrigerator.

[0082] The cabinet 100 may also include a cabinet insulation layer, which may be disposed between the cabinet liner and the cabinet shell. The cabinet insulation layer can insulate the storage compartment 101 to minimize heat exchange between the storage compartment 101 and the outside of the refrigerator, which helps to ensure the cooling effect of the refrigerator.

[0083] The refrigerator in this embodiment may further include a refrigeration system for reducing the air temperature in the storage compartment 101. Exemplarily, the refrigeration system may be housed within the cabinet 100. The refrigeration system may include a compressor, condenser, expansion valve, and evaporator connected in a cycle.

[0084] During refrigeration system operation, the compressor compresses refrigerant vapor to generate high-temperature, high-pressure refrigerant vapor, which is then transported to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then transported to the expansion valve. The expansion valve reduces the pressure of the refrigerant liquid, transforming the high-pressure, low-temperature refrigerant liquid into a low-pressure, low-temperature refrigerant liquid, which is then transported to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside storage compartment 101.

[0085] Continue to refer to Figure 1 The refrigerator in this embodiment may further include a door 200, which is rotatably connected to the cabinet 100 to open or close the storage compartment 101. Exemplarily, the door 200 is hinged to the cabinet 100.

[0086] Each storage room 101 may be provided with one door 200; or, each storage room 101 may be provided with two doors 200, which may rotate in opposite directions to open or close the storage room 101.

[0087] Of course, in some possible implementations, the storage room 101 is provided with a drawer 500, and the outer end of the drawer 500 forms a door 200.

[0088] In some embodiments, the door 200 may include an inner door liner. When the door 200 is closed to the refrigerator compartment, the inner door liner faces the refrigerator compartment.

[0089] The door 200 may include a door outer shell; the door outer shell may be attached to the outside of the door inner liner to form the appearance of the door 200. The door outer shell may be rotatably connected to the cabinet 100 to allow the door 200 to open or close the refrigerator compartment.

[0090] The door 200 may also include a door insulation component, which can be disposed within the gap between the inner door liner and the outer door shell. The door insulation component insulates the storage compartment 101 to minimize heat exchange between the storage compartment 101 and the outside of the refrigerator, thus ensuring the refrigerator's cooling effect. The door insulation component can be a foam layer.

[0091] In some embodiments, a door shelf 300 is provided on the side of the door 200 facing the storage compartment 101 to increase the storage space of the refrigerator. The door shelf 300 is configured to form a storage cavity with an upward-facing opening 613 for storing items. For example, the door shelf 300 is provided on the side of the door 200 facing the refrigerator compartment.

[0092] like Figure 2 As shown, in some embodiments of this application, multiple door shelves 300 may be provided, and the multiple door shelves 300 are arranged at intervals along the height direction of the door body 200.

[0093] Continue to refer to Figure 1 and Figure 2 In some embodiments of this application, the refrigerator may further include a drawer 500, which is pull-out relative to the body 100. For example, the drawer 500 is configured to extend along the depth direction of the refrigerator (corresponding to...). Figure 1 The drawer (in the Y-axis direction) can be pulled out to open or close the drawer 500.

[0094] In some embodiments, drawer 500 is installed in a refrigerator compartment to form a refrigerated storage space.

[0095] In other embodiments, drawer 500 is installed in the freezer liner to form a freezer storage space.

[0096] The outer end of drawer 500, i.e. the front end of drawer 500, can be provided with an outer cover plate or the like to form the door 200 of drawer 500, so that the outer end of drawer 500 is exposed to the external environment, and drawer 500 can be pulled out directly.

[0097] Of course, drawer 500 can also be located inside storage compartment 101. For example, refrigerated drawer 500 is installed inside the refrigeration compartment, and when door 200 is closed, drawer 500 is hidden inside the refrigeration compartment.

[0098] In some embodiments of this application, the refrigerator may further include a movable component configured to form a storage cavity; the movable component may move relative to the cabinet 100 to open or close.

[0099] The movable component may include the door body 200 on which the door shelf 300 is installed, and the movable component may include the drawer 500.

[0100] During the movement of the moving component relative to the box 100, the items in the storage cavity are prone to tipping over under the action of inertial force, especially some bottles and jars, which have a high center of gravity and are prone to tipping over when opening and closing the door or pulling out the drawer 500.

[0101] Combination Figure 3 and Figure 4 In some embodiments of this application, the refrigerator may further include: a limiting mechanism 400, which is mounted on the moving member and is configured to restrict items in the storage cavity so that the items in the storage cavity remain fixed and reduce the possibility of the items in the storage cavity tipping over when the moving member moves relative to the cabinet 100.

[0102] Continue to refer to Figure 3 and Figure 4 The limiting mechanism 400 includes a clamping component 600, which is used to clamp an item in the storage cavity so that the item is fixed relative to the storage cavity.

[0103] The limiting mechanism 400 may further include a height adjustment assembly 700, one side of which is mounted to the movable member, and the other side of which is connected to the clamping assembly 600. The height adjustment assembly 700 is configured to adjust the clamping assembly 600 along the height direction of the refrigerator (corresponding to...). Figure 1 The position of the limiting mechanism 400 (in the Z-axis direction) is adjusted to change the clamping position along the height direction of the refrigerator, so that the limiting mechanism 400 can adapt to items of different heights.

[0104] Therefore, the refrigerator of this embodiment, by providing a limiting mechanism 400 on the moving component, fixes the items in the storage cavity, so that the position of the items in the storage cavity is fixed relative to the moving component, preventing the items in the storage cavity from tipping over during the movement of the moving component, improving the stability of the items in the storage cavity, and thus improving the safety of the refrigerator. The limiting mechanism 400 is provided with a clamping assembly 600, which includes two clamping arms 610 forming a clamping cavity 611 to clamp the items in the storage cavity. The two clamping arms 610 are configured to be movable relative to each other to adjust the size of the gap between the two clamping arms 610, so that the clamping cavity 611 can clamp and fix items of different sizes, improving the versatility of the limiting mechanism 400. The limiting mechanism 400, by setting the height adjustment component 700, adjusts the position of the clamping component 600 along the height direction of the door body 200, so that the clamping component 600 can clamp items of different heights, or clamp items at different height positions. This not only improves the versatility of the limiting mechanism 400, but also improves the reliability of the limiting mechanism 400 in clamping items.

[0105] The following description uses the example of the limit mechanism 400 installed on the door body 200 to illustrate the structure and function of the limit mechanism 400.

[0106] Reference Figures 3 to 5 In some embodiments of this application, a limiting mechanism 400 is installed on the side of the door 200 facing the storage compartment 101, wherein the limiting mechanism 400 is installed on the inner liner of the door. The limiting mechanism 400 is located above the door shelf 300 to limit and fix the items inside the door shelf 300.

[0107] In certain usage scenarios, the limiting mechanism 400 can also be installed on the side wall of the door shelf 300 to limit and fix the items inside the door shelf 300.

[0108] The clamping assembly 600 of the limiting mechanism 400 includes two clamping arms 610, which enclose a clamping cavity 611 for clamping an item within the door shelf 300. In some embodiments, the two clamping arms 610 are spaced apart along the length of the door shelf 300 to form the clamping cavity 611.

[0109] In some possible implementations, one side of each of the two gripping arms 610 is a gripping surface 612 for contacting the item to be gripped. The gripping surface 612 is curved, for example, an arc surface, to match the shape of bottles and jars, thereby improving the reliability and firmness of the gripping arms 610 in holding the item.

[0110] In some embodiments, the two clamping arms 610 may be arc-shaped to form a clamping surface 612 that is curved.

[0111] In some embodiments, the clamping surface 612 is provided with an anti-slip pad, such as a rubber pad, which not only helps to increase the friction with the item to be clamped, thereby improving the reliability of clamping the item; but also helps to form an elastic contact with the item to be clamped, avoiding hard contact between the clamping surface 612 and the item to be clamped.

[0112] Continue to refer to Figures 3 to 5 In this embodiment, the two clamping arms 610 have an opening 613 on the side away from the height adjustment assembly 700. This not only allows items in the clamping cavity 611 to be picked up and put in along the height direction of the door shelf 300, but also allows items to be picked up and put in through the opening 613, improving the convenience of the application of the limiting mechanism 400.

[0113] In some embodiments of this application, the two clamping arms 610 are configured to be relatively movable to adjust the size of the gap between the two clamping arms 610, thereby enabling the clamping cavity 611 to clamp and fix items of different sizes, improving the versatility of the limiting mechanism 400.

[0114] In this embodiment, one side of the height adjustment component 700 is installed on the side of the door 200 facing the storage compartment 101, and the other side of the height adjustment component 700 is connected to the clamping component 600. The height adjustment component 700 is configured to adjust the position of the clamping component 600 and the door shelf 300 along the height direction of the door 200.

[0115] There are several ways to connect the height adjustment component 700 to the door body 200, such as snap-fitting, screw connection, adhesive bonding, or magnetic attachment. The height adjustment component 700 and door body 200 are detachably connected, facilitating the assembly and disassembly of the limiting mechanism 400, allowing users to selectively use the limiting mechanism 400 and making its application more flexible.

[0116] When the limiting mechanism 400 is applied inside the drawer 500, the height adjustment component 700 is connected to the inner wall of the drawer 500 to limit and fix the items inside the drawer 500.

[0117] There are various ways to connect the height adjustment component 700 and the clamping component 600, such as snap-fit ​​or screw connection.

[0118] In some embodiments, the height adjustment component 700 is configured to adjust the clamping component 600 along the height direction of the door body 200 (corresponding to...). Figure 1 The clamping assembly 600 and the door shelf 300 move along the Z-axis direction, thereby adjusting the position of the clamping assembly 600 and the door shelf 300 along the height direction of the door body 200.

[0119] In other embodiments, the height adjustment component 700 is configured to adjust the rotation of the clamping component 600 relative to the horizontal plane of the door body 200, thereby adjusting the position of the clamping component 600 and the door shelf 300 along the height direction of the door body 200. The horizontal plane of the door body 200 is defined by the thickness and width directions of the door body 200, for example... Figure 1 In the middle, the horizontal plane of the door body 200 corresponds to the XY plane.

[0120] In some embodiments, multiple limiting mechanisms 400 are provided, and the multiple limiting mechanisms 400 are arranged at intervals along the length direction of the door shelf 300, so that multiple items in the length direction of the door shelf 300 can be fixed in position.

[0121] In some embodiments, multiple limiting mechanisms 400 are arranged at intervals along the height direction of the door body 200. For example, for the same item, such as a tall bottled beverage, multiple limiting mechanisms 400 can be arranged at intervals along the height direction of the door body 200 to improve the reliability of the fixation. As another example, multiple door shelves 300 can be provided along the height direction of the door body 200, and each door shelf 300 is provided with at least one limiting mechanism 400.

[0122] In some embodiments, when the limiting mechanism 400 is applied inside the drawer 500, multiple limiting mechanisms 400 can be spaced apart along the side wall of the drawer 500 to clamp and fix items in different positions.

[0123] Therefore, the refrigerator of this embodiment increases storage space by providing a door shelf 300 on the side of the door 200 facing the storage compartment 101. A limiting mechanism 400 is provided on the side of the door 200 facing the storage compartment 101 to fix the items inside the door shelf 300, ensuring the items are positioned relative to the door shelf 300. This prevents items from tipping over or falling during door opening and closing, improving the stability of the items and thus enhancing the refrigerator's safety. The limiting mechanism 400 includes a clamping assembly 600, comprising two clamping arms 610 forming a clamping cavity 611 to clamp items inside the door shelf 300. The two clamping arms 610 are configured to move relative to each other to adjust the gap between them, allowing the clamping cavity 611 to clamp and fix items of different sizes, thus improving the versatility of the limiting mechanism 400. The limiting mechanism 400, by setting a height adjustment component 700, adjusts the position of the clamping component 600 and the door shelf 300 along the height direction of the door body 200, so that the clamping component 600 can clamp items of different heights, or clamp items at different height positions. This not only improves the versatility of the limiting mechanism 400, but also improves the reliability of the limiting mechanism 400 in clamping items.

[0124] Combination Figure 5 and Figure 6 In some embodiments of this application, the height adjustment component 700 may include a first connector 710, one end of which is fixedly connected to the clamping component 600. The fixed connection between the first connector 710 and the clamping component 600 includes, but is not limited to, snap-fit, screw connection, etc.

[0125] The height adjustment assembly 700 may include a second connector 720, one end of which is fixedly connected to the side of the door 200 facing the storage compartment 101, and the other end of which is hinged to the other end of the first connector 710, so that the first connector 710 and the second connector 720 rotate relative to each other, thereby causing the clamping assembly 600 to rotate relative to the horizontal plane of the door 200, so as to adjust the position of the clamping assembly 600 and the door shelf 300 along the height direction of the door 200, so that the door shelf 300 can be applied to items of different heights and improves the versatility of the limiting mechanism 400.

[0126] The horizontal plane of the door 200 is perpendicular to the height direction of the door 200.

[0127] In this embodiment, the height adjustment component 700 is fixedly connected to the clamping component 600 by a first connector 710 and connected to the inner liner of the door body 200 by a second connector 720. The clamping component 600 can rotate relative to the horizontal plane of the door body 200 by hinged connection of the first connector 710 and the second connector 720, thereby adjusting the position of the clamping component 600 and the door shelf 300 along the height direction of the door body 200. The structure and adjustment are simple.

[0128] In some embodiments, the height adjustment assembly 700 further includes a pivot 730, which passes through the shaft holes of the first connector 710 and the second connector 720. The pivot 730 is arranged along the length of the door shelf 300.

[0129] The first connector 710 forms a first shaft hole 711, and the second connector 720 forms a second shaft hole 721, which is coaxially arranged with the first shaft hole 711. The rotating shaft 730 passes through the first shaft hole 711 and the second shaft hole 721.

[0130] In some embodiments, the second connector 720 is configured to form an insertion port 722, such that hinge arms 723 are formed on both sides of the insertion port 722, and each of the two hinge arms 723 is provided with a second shaft hole 721. The first connector 710 is inserted into the insertion port 722, such that the first shaft hole 711 and the second shaft hole 721 are arranged coaxially, which helps to improve the stability of the installation of the rotating shaft 730.

[0131] The height adjustment assembly 700 may further include a first adjusting member 740, which is threadedly connected to the end of the rotating shaft 730. The first adjusting member 740 may be a nut or other structure with a threaded hole, and is threadedly connected to the end of the rotating shaft 730.

[0132] The first adjusting member 740 is configured to lock the first connecting member 710 and the second connecting member 720 to restrict the relative rotation of the first connecting member 710 and the second connecting member 720, so that the first connecting member 710 and the second connecting member 720 are relatively fixed, thereby fixing the clamping assembly 600 in a set position.

[0133] Alternatively, the first adjusting member 740 is configured to unlock the first connecting member 710 and the second connecting member 720 so that the first connecting member 710 and the second connecting member 720 rotate relative to each other so that the clamping assembly 600 rotates relative to the horizontal plane of the door body 200, adjusting the position of the clamping assembly 600 and the door shelf 300 along the height direction of the door body 200.

[0134] In some embodiments, the rotating shaft 730 includes a shaft body 731 and a limiting portion 732. The shaft body 731 passes through a first shaft hole 711 and a second shaft hole 721. One end of the shaft body 731 is threadedly connected to a first adjusting member 740. The other end of the shaft body 731 is provided with a limiting portion 732, which protrudes from the edge of the shaft body 731 so that the limiting portion 732 abuts against a hinge arm 723.

[0135] The first adjusting member 740 is threadedly connected to the rotating shaft 730. When the first adjusting member 740 moves toward the limiting part 732, the first adjusting member 740 causes the two hinge arms 723 to abut against the first connecting member 710, thereby locking the first connecting member 710 and the second connecting member 720 to restrict the relative rotation of the first connecting member 710 and the second connecting member 720. When the first adjusting member 740 rotates relative to the rotating shaft 730 and moves away from the limiting part 732, the first connecting member 710 and the second connecting member 720 are unlocked, and the first connecting member 710 and the second connecting member 720 rotate relative to each other to adjust the position of the clamping assembly 600 and the door shelf 300 along the height direction of the door body 200.

[0136] In this embodiment, the first connector 710 and the second connector 720 of the height adjustment assembly 700 are hinged by a pivot 730, and the first adjustment member 740 is threadedly connected to the pivot 730. Tightening and loosening the first adjustment member 740 can lock and unlock the first connector 710 and the second connector 720. The structure is simple and the cost is low; the adjustment operation is simple and convenient.

[0137] In some embodiments of this application, a suction cup 750 is provided at one end of the second connector 720, and the suction cup 750 is attached to the side of the door 200 facing the storage compartment 101. The suction cup 750 is also provided at the end of the second connector 720 opposite to the first connector 710. Utilizing the suction force of the suction cup 750, not only is the height adjustment component 700 connected to the door 200, but the user can also flexibly adjust the position of the limiting mechanism 400 according to actual usage, improving the flexibility of the limiting mechanism 400 application. Furthermore, there is no need to provide a fixing structure on the door 200 or drawer 500, making the structure of the limiting mechanism 400 simple and cost-effective.

[0138] In some other embodiments of this application, a first magnetic element is provided at one end of the second connector 720, and a second magnetic element is provided on the side of the door 200 facing the storage room 101, and the second magnetic element and the first magnetic element are magnetically attracted to each other.

[0139] One of the first and second magnetic components can be a magnet, and the other can be a metal component such as iron, cobalt, or nickel that can be attracted by a magnet. Of course, both the first and second magnetic components can also be magnets, using the attraction between opposite poles of magnets to achieve a fixed connection between the second connector 720 and the door body 200.

[0140] The second magnetic component can be embedded between the inner door liner and the outer door shell. There is no fixed structure on the inside of the inner door liner, which helps to ensure the structural integrity of the inside of the door.

[0141] For example, the second magnetic element is a long strip, such as a long strip extending along the length of the door shelf 300. In this way, by changing the position where the first magnetic element and the second magnetic element are magnetically attracted, the position of the limiting mechanism 400 can be flexibly adjusted, making the adjustment of the limiting mechanism 400 more flexible.

[0142] This application embodiment uses a first magnetic component and a second magnetic component that attract each other to achieve the connection between the height adjustment component 700 and the door body 200. This not only allows for flexible adjustment of the position of the limiting mechanism 400, but also makes the connection of the limiting mechanism 400 stable and reliable, and makes the assembly and disassembly of the limiting mechanism 400 convenient.

[0143] In other embodiments of this application, the height adjustment component 700 includes:

[0144] The first connector 710, one end of which is fixedly connected to the clamping assembly 600;

[0145] The second connector 720 has one end fixedly connected to the side of the door 200 facing the storage room 101, and the second connector 720 and the first connector 710 are slidably connected along the height direction of the door 200.

[0146] The limiting member is configured to lock the first connector 710 and the second connector 720, or to unlock the first connector 710 and the second connector 720 so that the first connector 710 and the second connector 720 slide relative to each other.

[0147] For example, one of the first connector 710 and the second connector 720 is provided with a slide rail, and the other is provided with a mating part, which is slidably mounted on the slide rail. The slide rail extends along the height direction of the door body 200, so that the first connector 710 and the second connector 720 can slide along the height direction of the door body 200, thereby adjusting the position of the clamping assembly 600 along the height direction of the door body 200.

[0148] For example, one of the first connector 710 and the second connector 720 is provided with a threaded hole, and a limiting member is threadedly connected to the threaded hole, with the end of the limiting member abutting against the other to lock the first connector 710 and the second connector 720, thereby fixing the first connector 710 and the second connector 720 relative to each other. Alternatively, the limiting member can be unscrewed from the threaded hole to unlock the first connector 710 and the second connector 720, allowing the first connector 710 and the second connector 720 to slide relative to each other.

[0149] In this embodiment, the first connector 710 and the second connector 720 are slidably connected along the height direction of the door body 200 to adjust the position of the clamping assembly 600 along the height direction of the door body 200; and the first connector 710 and the second connector 720 are unlocked or locked by the limiting member, so that the height position of the clamping assembly 600 can be adjusted and fixed.

[0150] Combination Figures 3 to 5 as well as Figure 7 In some implementations, the clamping assembly 600 further includes a mounting base 620, which is connected to the height adjustment assembly 700. The mounting base 620 is fixedly connected to the first connector 710 of the height adjustment assembly 700.

[0151] At least one of the two clamping arms 610 is slidably mounted to the mounting base 620. For example, one of the two clamping arms 610 is slidably mounted to the mounting base 620, allowing that clamping arm 610 to slide relative to the mounting base 620 to adjust the spacing between the two clamping arms 610, so that the clamping cavity 611 can clamp items of different diameters. Alternatively, both clamping arms 610 can be slidably mounted to the mounting base 620, and both clamping arms 610 can slide relative to the mounting base 620 to adjust the spacing between the two clamping arms 610, allowing for faster adjustment.

[0152] Combination Figure 7 and Figure 8 In some embodiments, the mounting base 620 is provided with a slide rail 623, which extends along the length of the door shelf 300. The clamping arm 610 is provided with a slider 614, which is slidably mounted in the slide rail 623, so that the clamping arm 610 slides relative to the mounting base 620.

[0153] In some embodiments, to improve the reliability of the sliding connection between the clamping arm 610 and the mounting base 620, multiple slide rails 623 may be provided, and the multiple slide rails 623 are spaced apart along a first direction, which may be perpendicular to the extension direction of the slide rails 623. Correspondingly, multiple sliders 614 are provided on the clamping arm 610, and each slider 614 is slidably mounted in one of the slide rails 623.

[0154] For example, two slide rails 623 are provided at intervals along the height direction of the door body 200, which can improve the reliability of the sliding connection between the clamping arm 610 and the mounting base 620, and also avoid the increase in the volume of the mounting base 620 due to the provision of too many slide rails 623.

[0155] In some embodiments, combined with Figure 8 and Figure 9To prevent the slider 614 from dislodging from the slide rail 623, a limiting structure is provided between the slider 614 and the slide rail 623. The limiting structure may include a limiting protrusion 615 provided on the slide rail and a limiting groove 6231 provided on the slide rail 623. The slider 614 is prevented from dislodging from the slide rail 623 by the cooperation of the limiting protrusion 615 and the limiting groove 6231.

[0156] The clamping assembly 600 of this application embodiment provides a mounting mechanism for the clamping arms 610 by setting a mounting base 620. At least one of the two clamping arms 610 is slidably mounted on the mounting base 620, so that the two clamping arms 610 can slide relative to each other to adjust the interval between the two clamping arms 610, so that the clamping cavity 611 can clamp items of different diameters.

[0157] Continue to refer to Figure 7 In some embodiments of this application, the clamping assembly 600 may further include two connecting arms 630, one end of each connecting arm 630 being rotatably connected to one end of each clamping arm 610.

[0158] For example, the clamping assembly 600 may also include two first connecting shafts 650, and the end of the connecting arm 630 is rotatably connected to the clamping arm 610 through the first connecting shafts 650, so that the connecting arm 630 and the clamping arm 610 can rotate relative to each other.

[0159] The clamping assembly 600 may also include a second adjusting member 640, which is rotatably mounted on the mounting base 620 and located between the two connecting arms 630; the second adjusting member 640 is rotatably connected to the other end of the two connecting arms 630.

[0160] The second adjusting member 640 is located between the two connecting arms 630, and the two ends of the connecting arms 630 are rotatably connected to the clamping arm 610 and the second adjusting member 640, respectively.

[0161] For example, the clamping assembly 600 may also include two second connecting shafts 660, and two connecting arms 630 are rotatably connected to the second adjusting member 640 through the second connecting shafts 660.

[0162] The first connecting shaft 650 and the second connecting shaft 660 are axially parallel and both perpendicular to the wheel surface of the second adjusting member 640. The two second connecting shafts 660 can be arranged at intervals along the horizontal centerline of the second adjusting member 640. The horizontal centerline of the second adjusting member 640 passes through the center of the second adjusting member 640 and is parallel to the length direction of the door shelf 300.

[0163] When the second adjusting member 640 rotates, it drives the two connecting arms 630 to rotate in opposite directions, so that the two clamping arms 610 slide towards or away from each other. In this way, the interval between the two clamping arms 610 can be adjusted by rotating the second adjusting member 640, which is simple to operate.

[0164] exist Figure 3 In the structure shown, the gap between the two clamping arms 610 is at its maximum. The second adjusting member 640 rotates clockwise (corresponding to...). Figure 3 When the second adjusting member 640 rotates counterclockwise (direction A), the left connecting arm 630 rotates upward and the right connecting arm 630 rotates downward, thereby causing the two clamping arms 610 to move towards each other, reducing the gap between the two clamping arms 610. Alternatively, the second adjusting member 640 rotates counterclockwise (direction A). Figure 3 When rotating in the opposite direction of A, the left connecting arm 630 rotates downward and the right connecting arm 630 rotates upward, thereby causing the two clamping arms 610 to move toward each other, and the gap between the two clamping arms 610 becomes smaller.

[0165] In some embodiments, combined with Figure 9 The clamping arm 610 may include clamping portions 616 and connecting portions 617. A clamping cavity 611 is formed between the two clamping portions 616, and clamping surfaces 612 are formed on the sides of the two clamping portions 616 facing each other. The clamping portions 616 extend in a direction perpendicular to the inner surface of the door body 200. One end of the clamping portion 616 is connected to the connecting portion 617. Exemplarily, the clamping portion 616 and the connecting portion 617 are integrally formed as a single piece, resulting in a stable structure. The other ends of the two clamping portions 616 form openings 613.

[0166] The connecting part 617 is connected to both the mounting base 620 and the connecting arm 630. A slider 614 is provided on the side of the connecting part 617 facing the mounting base 620, and the other side of the connecting part 617 away from the mounting base 620 is connected to the connecting arm 630 via a first connecting shaft 650. This avoids interference between the rotation of the connecting arm 630 and the sliding of the clamping arm 610.

[0167] In this embodiment, the clamping assembly 600 is provided with a second adjusting member 640 and two connecting arms 630. The second adjusting member 640 is connected to the clamping arm 610 through the connecting arms 630. By utilizing the rotational connection between the two ends of the connecting arm 630 and the second adjusting member 640 and the clamping arm 610, the rotational movement of the second adjusting member 640 is adjusted to the movement of the clamping arm 610, thereby adjusting the interval between the two clamping arms 610. The structure is simple and stable.

[0168] In some embodiments of this application, combined with Figure 8 The mounting base 620 is provided with a mounting hole 621, and the second adjusting member 640 is rotatably connected to the mounting hole 621.

[0169] Combination Figure 8 and Figure 10 The mounting hole 621 has a protrusion 641 on one of the holes and the second adjusting member 640, and the other has a plurality of recesses 622. The plurality of recesses 622 are arranged at intervals along the circumference of the second adjusting member 640; the protrusion 641 and the recesses 622 cooperate with each other.

[0170] The multiple recesses 622 can be evenly spaced along the circumference of the second adjusting member 640 to improve the uniformity of the rotation adjustment of the second adjusting member 640.

[0171] For example, the mounting hole 621 has a plurality of recesses 622 on its wall, and the plurality of recesses 622 are arranged at intervals along the circumference of the mounting hole 621. A protrusion 641 is provided on the second adjusting member 640. The cooperation between the protrusion 641 and the recesses 622 provides resistance to the rotation between the second adjusting member 640 and the mounting hole 621, preventing the second adjusting member 640 from rotating arbitrarily between the two holes, and improving the reliability and stability of the limiting mechanism 400 in clamping the item.

[0172] Continue to refer to Figure 10 The second adjusting member 640 includes a body portion 642, which is located on the side of the mounting base 620 opposite to the height adjusting assembly 700. Two second connecting shafts 660 are provided on the wheel surface of the body portion 642 opposite to the mounting base 620 for rotatable connection with two connecting arms 630. The diameter of the body portion 642 is larger than the diameter of the mounting hole 621, serving as a limit to prevent the second adjusting member 640 from dislodging from the mounting hole 621.

[0173] A third connecting shaft 643 is provided on the wheel surface of the main body 642 facing the mounting base 620, and the third connecting shaft 643 is rotatably mounted in the mounting hole 621. A protrusion 641 may be provided on the third connecting shaft 643. The end of the third connecting shaft 643 opposite to the main body 642 protrudes from the mounting hole 621.

[0174] Combination Figure 7 The clamping assembly 600 may also include an operating member 670, which is located on the side of the mounting base 620 away from the clamping arm 610. The operating member 670 is connected to the third connecting shaft 643 of the second adjusting member 640, which not only facilitates the operation of the second adjusting member 640, but also cooperates with the main body 642 to install the second adjusting member 640 in the mounting hole 621, preventing the second adjusting member 640 from coming out of the mounting hole 621.
