Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and in particular to a refrigerator. Background Technology

[0002] Refrigerators have two main storage areas: the cabinet (which contains storage compartments, and may also include shelves or drawers) and the door (where bottle holders may be located). Refrigerator shelves are glass panels fixed to the inner liner of the refrigerator, and there is no front limit to the items placed on them. Refrigerator drawers are similar to regular drawers, with front and back limits. Bottle holders on the refrigerator door are typically L-shaped or U-shaped containers, also with front and back limits. Of these three storage structures, the lack of a front limit on the shelves means that if items extend a certain distance beyond the shelf, they will interfere with the bottle holders, causing the refrigerator door to not close properly, or even damaging the items due to the interference, resulting in a very poor user experience.

[0003] Currently, there are two situations where the refrigerator door cannot close properly: 1. There is a gap between the bottle holder and the shelf, causing food placed by the user to protrude from the shelf, interfering with the closing of the door; 2. The bottle holder is above the shelf, extending into the space where food is placed on the shelf, causing food placed by the user within the shelf's area to interfere with the bottle holder. These situations of interference between the bottle holder and food on the shelf make it inconvenient for users to place frozen foods, reducing the user experience.

[0004] To avoid this situation, existing technologies have designed foldable shelves, but these typically require sliding rails on the refrigerator door liner and bottle holders, making the structure complex, prone to dust and water accumulation, difficult to clean, and affecting the user experience. Summary of the Invention

[0005] One objective of a first aspect of the present invention is to provide a refrigerator that solves the problem of interference between the bottle holder and the items on the shelf in the prior art.

[0006] Another objective of the first aspect of the present invention is to solve the problems of existing bottle holders being complex in structure, costly, and difficult to clean.

[0007] In particular, the present invention also provides a refrigerator, comprising:

[0008] A door for opening and closing the storage compartment of the refrigerator, the door including a door liner disposed on the surface of the door facing the storage compartment;

[0009] The bottle holder is disposed at the door liner. The bottle holder includes a flexible bottom wall and two sets of linkage assemblies connected to both ends of the flexible bottom wall. Each set of linkage assemblies includes a first link and a second link arranged in a cross configuration. One end of the first link and one end of the second link in the same group as the first link are rotatably connected to the door liner. The intersection of the first link and the second link is configured to be movable so that when the side of the flexible bottom wall is subjected to force, the two sets of linkage assemblies move to drive the bottom wall to extend or retract, thereby enabling the bottle holder to extend or retract relative to the door liner.

[0010] Optionally, the bottle holder further includes a limiting clamp disposed at the intersection of one or two sets of the linkage assemblies. Each limiting clamp includes a rotating shaft. The first link and the second link of the same set of linkage assemblies are connected to each other through the rotating shaft and both rotate relative to the rotating shaft. The limiting clamp is also configured to fix the first link and the second link when the first link of the same set moves relative to the second link to the bottle holder in a first state. The first state is when the intersection of the linkage assemblies is located at the middle position of the first link and the second link, and the bottle holder is in an extended state.

[0011] Optionally, each of the first links is provided with a strip hole, the strip hole extending from the middle of the first link along the extension direction of the first link to a position near one end of the door liner, and each of the second links is provided with a circular through hole at the middle position;

[0012] The rotating shaft passes through the circular through hole and the strip hole of the same group to connect the first connecting rod and the second connecting rod of the same group. While the first connecting rod of the same group rotates relative to the second connecting rod about the rotating shaft, the limiting clamp also moves along the strip hole with the second connecting rod, so that the bottle holder switches between the first state and the second state. The second state is when the connecting rod assembly moves to the state where the bottle holder is in retraction.

[0013] Optionally, each of the first connecting rods is provided with a groove located on the side of the strip hole away from the door liner;

[0014] Each of the limiting clamps further includes a connecting plate perpendicular to the axis of the rotating shaft. A boss extending toward the groove is also provided on the connecting plate. When the connecting rod assembly moves to the bottle holder in the first state, the boss is engaged in the groove to fix the first connecting rod and the second connecting rod. When the boss separates from the groove, the rotating shaft can run in the strip hole, so that the bottle holder can switch from the first state to the second state.

[0015] Optionally, the bottle holder further includes:

[0016] A first support rod is connected between the ends of the two second connecting rods that are connected to the door liner; and

[0017] The second support rod is connected between the ends of the two first connecting rods that are away from the door liner;

[0018] The bottom wall is connected to the first support rod and the second support rod.

[0019] Optionally, the bottle holder further includes:

[0020] A third support rod is connected between the ends of the two second links that are furthest from the door liner; and

[0021] A flexible sidewall is connected between the second support rod and the third support rod.

[0022] Optionally, the bottom wall and the side wall form an integral structure, and three cylindrical structures are formed at the connection with the first support rod, the second support rod and the third support rod, so that the first support rod, the second support rod and the third support rod pass through the cylindrical structures and are then connected to the corresponding connecting rods.

[0023] Optionally, the bottle holder further includes at least one baffle line arranged from the middle position of the connecting rod towards its end, with both ends of each baffle line symmetrically fixed to the first connecting rod with the middle as the boundary.

[0024] The second connecting rod is provided with at least one through hole, the number of which corresponds to the number of the baffles, such that each baffle passes through the corresponding through hole, wherein the axis of the through hole is located in a plane perpendicular to the axis of the rotation shaft.

[0025] Optionally, it also includes a positioning piece rotatably connected to the door liner so that the positioning piece can switch between a third state and a fourth state. When the positioning piece is in the third state, it can fix the bottle holder in the second state. When the positioning piece switches from the third state to the fourth state, the bottle holder is released so that it can switch from the second state to the first state.

[0026] Optionally, a baffle is also provided at the door liner. The baffle is disposed on the side of the positioning piece to prevent the positioning piece from continuing to rotate when the positioning piece rotates to the third state, so as to fix the bottle holder in the second state.

[0027] In this design, a bottle holder is installed at the door liner of the refrigerator. When subjected to external force, the bottle holder can extend and retract relative to the door liner. When there are many items stored in the storage compartment, the bottle holder can be retracted to increase the storage compartment space and avoid interference between the bottle holder and the items stored in the refrigerator compartment, thereby increasing the refrigerator's functionality and improving the user experience.

[0028] In this design, the bottle holder is directly connected to the bottom wall via two sets of connecting rod assemblies positioned on the left and right sides of the refrigerator door liner. Each set of connecting rod assemblies includes a first connecting rod and a second connecting rod arranged in a cross configuration. One end of each first connecting rod and one end of each second connecting rod are rotatably connected to the door liner. The intersection points of each set of connecting rod assemblies are movable, and the bottom wall of the bottle holder is flexible. Therefore, the bottle holder can extend and retract under external force. Furthermore, when the bottle holder extends and retracts, there is no need to install additional sliding rails at the door liner position. The structure is simple and avoids the problem of difficulty in cleaning due to long-term exposure.

[0029] The bottle holder in this design is equipped with a limiting clamp. This limiting clamp serves two purposes: firstly, it acts as a pivot at the intersection of the linkage assembly, and secondly, it limits the running trajectory of the linkage assembly. Additionally, when the bottle holder is in the first state, it also fixes the linkage assembly, thereby improving the stability of the bottle holder.

[0030] This design incorporates multiple baffles at the linkage assembly. When these baffles are placed at the linkage assembly of the bottle holder, they create a spiderweb-like structure on the side of the linkage assembly, preventing items from falling off the side of the bottle holder.

[0031] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0040] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0041] Figure 1 This is a schematic structural diagram of a refrigerator according to a specific embodiment of the present invention. Figure 2 This is a schematic structural diagram of a bottle holder disposed at the door liner according to a specific embodiment of the present invention; specifically, as shown... Figure 1 and Figure 2 As shown, the refrigerator 100 of this embodiment may include a door 200 and a bottle holder 300. Specifically, the door 200 of this embodiment is used to open and close the storage compartment 101 of the refrigerator 100. The door 200 may include a door liner 201 disposed on the surface of the door 200 facing the storage compartment. The bottle holder 300 is disposed at the door liner 201. The bottle holder 300 may include a flexible bottom wall 10 and two sets of connecting rod assemblies 20 connected to both ends of the flexible bottom wall 10. Each set of connecting rod assemblies 20 includes a first connecting rod 21 and a second connecting rod 22 arranged in a cross configuration. One end of the first connecting rod 21 and one end of the second connecting rod 22 in the same group as the first connecting rod 21 are respectively rotatably connected to the door liner 201. The intersection of the first connecting rod 21 and the second connecting rod 22 is configured to be movable so that when the side of the flexible bottom wall 10 is subjected to force, the two sets of connecting rod assemblies 20 move to drive the bottom wall 10 to extend or retract, thereby allowing the bottle holder 300 to extend or retract relative to the door liner 201.

[0042] Specifically, in this embodiment, a bottle holder 300 is provided at the door liner 201 of the refrigerator. When the bottle holder 300 is subjected to external force, it can extend and retract relative to the door liner 201. When there are many items stored in the storage compartment, the bottle holder 300 can be retracted to increase the space of the storage compartment and avoid interference between the bottle holder 300 and the items stored in the refrigerator compartment, thereby increasing the refrigerator's functionality and improving the user experience.

[0043] Specifically, in this embodiment, two sets of connecting rod assemblies 20 arranged on the left and right sides of the refrigerator door liner 201 are directly connected to the bottom wall 10. Each set of connecting rod assemblies 20 includes a first connecting rod 21 and a second connecting rod 22 arranged in a cross configuration. One end of each first connecting rod 21 and one end of each second connecting rod 22 are rotatably connected to the door liner 201. The intersection point of each set of connecting rod assemblies 20 is movable, and the bottom wall 10 of the bottle holder 300 is flexible. Therefore, the bottle holder 300 in this embodiment can extend and retract when subjected to external force. The bottle holder 300 in this embodiment does not require additional slide rails at the door liner 201 position, has a simple structure, and will not have the problem of being difficult to clean due to long-term exposure.

[0044] Specifically, since the bottle holder 300 generally protrudes vertically from the door liner 201, and the direction of its extension and retraction is most likely perpendicular to the surface of the door liner 201, and the external forces acting on the bottle holder 300 are mostly perpendicular to the door liner 201, the side of the flexible bottom wall 10 in this embodiment generally refers to the side of the flexible bottom wall 10 away from the door liner, and the external forces acting on it are also basically located at this side position, and the direction of the force is basically perpendicular to the surface of the door liner 201.

[0045] Figure 3 This is a schematic structural diagram of a bottle holder disposed at a door liner according to another specific embodiment of the present invention; Figure 4 This is a schematic structural diagram of a bottle holder according to a specific embodiment of the present invention; Figure 5 This is a schematic structural diagram of a linkage assembly according to a specific embodiment of the present invention; Figure 6 This is a schematic structural diagram of a linkage assembly according to another specific embodiment of the present invention; Figure 7 This is a schematic exploded view of a linkage assembly according to a specific embodiment of the present invention. As a specific embodiment of the present invention, such as... Figures 2-7As shown, the bottle holder 300 of this embodiment may further include a limiting clamp 30 disposed at the intersection of one or two sets of linkage assemblies 20. Each limiting clamp 30 includes a rotating shaft 31. The first link 21 and the second link 22 of the same set of linkage assemblies 20 are interconnected through the rotating shaft 31 and both rotate relative to the rotating shaft 31. The limiting clamp 30 is also configured to fix the first link 21 and the second link 22 when the first link 21 of the same set moves relative to the second link 22 to the bottle holder 300 in a first state. The first state is when the intersection of the linkage assemblies 20 is located at the middle position of the first link 21 and the second link 22, and the bottle holder 300 is in an extended state.

[0046] Specifically, in this embodiment, when the bottle holder 300 is in the first state, the intersection point of the first link 21 and the second link 22 of each linkage assembly 20 is located at the middle position of the first link 21 and the second link 22. In actual use of the bottle holder 300, since the linkage assembly 20 is movable, if there is no additional component to fix the bottle holder 300 in the first state, the bottle holder 300 will be unstable, causing considerable inconvenience in use.

[0047] In this embodiment, a limiting clamp 30 is provided at the bottle holder 300. The limiting clamp 30 can be used as a pivot at the intersection of the linkage assembly 20, and it also limits the running trajectory of the linkage assembly 20. At the same time, when the bottle holder 300 is in the first state, it will also fix the linkage assembly 20, thereby improving the stability of the bottle holder 300.

[0048] Specifically, in this embodiment, a limiting clamp 30 can be provided at one of the connecting rod assemblies 20, or a limiting clamp 30 can be provided at each of the two connecting rod assemblies 20. Preferably, a limiting clamp 30 is provided at each of the two connecting rod assemblies 20 to improve the stability of the bottle holder 300.

[0049] As a specific embodiment of the present invention, each first link 21 of this embodiment is provided with a strip hole 211, which extends from the middle of the first link 21 along the extension direction of the first link 21 to a position near the door liner 201. Each second link 22 is provided with a circular through hole 221 at the middle position. The rotating shaft 31 passes through the circular through hole 221 and the strip hole 211 of the same group to connect the first link 21 and the second link 22 of the same group. While the first link 21 of the same group rotates relative to the second link 22 about the rotating shaft 31, the limiting clamp 30 also moves along the strip hole 211 with the second link 22, so that the bottle holder 300 switches between a first state and a second state. The second state is when the link assembly 20 moves to the state where the bottle holder 300 is in the retracted state.

[0050] Specifically, in this embodiment, a strip-shaped hole 211 is provided at the first connecting rod 21, and a circular through hole 221 is provided at the second connecting rod 22. Thus, when the rotating shaft 31 passes through the strip-shaped hole 211 and the circular through hole 221, the intersection point of the first connecting rod 21 and the second connecting rod 22 is fixed by the rotating shaft 31. Furthermore, when the first connecting rod 21 and the second connecting rod 22 are subjected to external force, their intersection point can only move along the strip-shaped hole 211 of the first connecting rod 21, thereby directly limiting their movement trajectory.

[0051] As a specific embodiment of the present invention, each first link 21 of this embodiment is provided with a groove 212 located on the side of the strip hole 211 away from the door liner 201. Each limiting clamp 30 may also include a connecting plate 32 perpendicular to the axis of the rotating shaft 31. A boss 33 extending toward the groove 212 is also provided on the connecting plate 32. When the link assembly 20 moves to the bottle holder 300 in the first state, the boss 33 is engaged in the groove 212 to fix the first link 21 and the second link 22. When the boss 33 is separated from the groove 212, the rotating shaft 31 can run in the strip hole 211, so that the bottle holder 300 can switch from the first state to the second state.

[0052] In this embodiment, when the bottle holder 300 is in the first state, the intersection of the first connecting rod 21 and the second connecting rod 22 is located exactly in the middle of each connecting rod. Due to the strip hole 211 provided at the first connecting rod 21, the bottle holder 300 is unstable when subjected to external force. In this embodiment, the groove 212 provided at the first connecting rod 21 and the boss 33 provided on the limiting clamp 30 cooperate with each other to limit the bottle holder 300 and improve the stability of the bottle holder 300.

[0053] Specifically, in this embodiment, a groove 212 is provided below the strip hole 211 of the first connecting rod 21. This groove 212 can be a blind hole or a through hole. The boss 33 on the limiting clamp 30 cooperates with the groove 212. When the bottle holder 300 is in the first state, the limiting clamp 30 is rotated until the boss 33 and the groove 212 are engaged, thereby fixing the connecting rod assembly 20. When it is necessary to retract the bottle holder 300, the limiting clamp 30 can be rotated to separate the boss 33 from the groove 212, thereby pushing the base and causing the bottle holder 300 to retract close to the door liner 201.

[0054] Specifically, such as Figure 7As shown, in this embodiment, the rotating shaft 31 and connecting plate 32 of the limiting clamp 30 can be separate structures. A cap 34 is provided at one end of the rotating shaft, and an external thread is provided at the other end. A through hole 321 is provided at the connecting plate 32. The rotating shaft 31 passes through the through hole at the connecting plate 32, then through the strip hole 211 at the first connecting rod 21 and the circular through hole 221 at the second connecting rod 22, and then engages with a nut 35. A spring 36 is also provided on the rotating shaft 31. When the nut 35 on the rotating shaft 31 is loosened, the spring 36 will continuously push the cap 34 to separate from the connecting plate 32. When a certain force is applied to the connecting plate 32, the boss 33 can be separated from the groove 212. When it is necessary to engage the boss 33 with the groove 212, the boss 33 can be moved to the position corresponding to the groove 212, and then the nut 35 can be tightened in the opposite direction. The nut 35 can then be tightened continuously.

[0055] As a specific embodiment of the present invention, such as Figure 2 , Figure 3 and Figure 4 As shown, the bottle holder 300 of this embodiment may further include a first support rod 41 and a second support rod 42. The first support rod 41 is connected between the ends of the two second connecting rods 22 that are connected to the door liner 201. The second support rod 42 is connected between the ends of the two first connecting rods 21 that are away from the door liner 201. The bottom wall 10 is connected to the first support rod 41 and the second support rod 42.

[0056] Specifically, in this embodiment, the first support rod 41 and the second support rod 42 are arranged between the two sets of connecting rod assemblies 20. The side of the bottom wall 10 closest to the door liner 201 is connected to the first support rod 41, and the side of the bottom wall 10 furthest from the door liner 201 is connected to the second support rod 42. The left and right sides of the bottom wall 10 respectively abut against the first connecting rod assembly 21 and the second connecting rod assembly 22, which can increase the load-bearing capacity of the bottom wall 10.

[0057] As a specific embodiment of the present invention, the bottle holder 300 may further include a third support rod 43 and a flexible sidewall 50. Specifically, the third support rod 43 is connected between the ends of the two second connecting rods 22 that are away from the door liner 201. The flexible sidewall 50 is connected between the second support rod 42 and the third support rod.

[0058] In this embodiment, the lower side of the flexible sidewall 50 is connected to the second support rod 42, and the upper side of the flexible sidewall 50 is connected to the third support rod 43, which can increase the strength and stability of the flexible sidewall 50.

[0059] Specifically, in this embodiment, the first support rod 41, the second support rod 42, and the third support rod 43 are all parallel to each other. When the bottle holder 300 is in the first state, the distance between the first support rod 41 and the second support rod 42 of the bottom wall 10 is the longest, and the bottom wall 10 is in an unfolded state. At the same time, the distance between the second support rod 42 and the third support rod 43 is the shortest, and the side wall 50 is in a bent state. When the bottle holder 300 is in the second state, the distance between the first support rod 41 and the second support rod 42 is the shortest, and the bottom wall 10 is in a bent state. At this time, the distance between the second support rod 42 and the third support rod 43 is the longest, and the side wall 50 is in an unfolded state.

[0060] Specifically, in this embodiment, both the bottom wall 10 and the side wall 50 are flexible and can be flexible plastic sheets. Both the bottom wall 10 and the side wall 50 can extend or bend. Specifically, a winding device can also be provided at the first support rod 41, the second support rod 42, or the third support rod 43 to store or release the bottom wall 10 and the side wall 50 when they extend or retract.

[0061] As a specific embodiment of the present invention, the bottom wall 10 and the side wall 50 form an integral structure, and three cylindrical structures are formed at the connection with the first support rod 41, the second support rod 42 and the third support rod 43, so that the first support rod 41, the second support rod 42 and the third support rod 43 pass through the cylindrical structures and are then connected to the corresponding connecting rods.

[0062] Specifically, a cylindrical structure is provided at the bottom wall 10 and the side wall 50 to connect with the first support rod 41, the second support rod 42 and the third support rod 43. When the support rod rotates with the connecting rod, the relative position between the bottom wall 10 and the side wall 50 and the support rod can also move. This avoids the bottom wall 10 or the side wall 50 from rotating when the support rod rotates, and avoids the bottom wall 10 or the side wall 50 from bending when it rotates with the support rod.

[0063] Specifically, the bottle holder 300 may further include at least one baffle line 60 arranged from the middle position of the first connecting rod 21 toward its end, with both ends of each baffle line 60 being symmetrically fixed to the first connecting rod 21 with the middle as the boundary. At least one through hole 224 is provided at the second connecting rod 22, the number of through holes 224 corresponding to the number of baffle lines 60, such that each baffle line 60 passes through the corresponding through hole 224, wherein the axis of the through hole 224 is located in a plane perpendicular to the axis of the rotation shaft 31.

[0064] Specifically, in this embodiment, one, two, three, four, five, or other baffle lines 60 can be provided at the bottle holder 300. These baffle lines 60 can be arranged sequentially. The baffle line 60 located above the first connecting rod 21 is fixedly connected at both ends to the upper and lower halves of the first connecting rod 21, respectively, and passes through the through hole 224 in the upper half of the second connecting rod 22, allowing the baffle line 60 to move at the through hole 224. Similarly, the baffle line 60 located below the first connecting rod 21 is also fixedly connected at both ends to the upper and lower halves of the first connecting rod 21, respectively, and passes through the through hole 224 in the lower half of the second connecting rod 22.

[0065] Specifically, when multiple baffles 60 are installed at the linkage assembly 20 of the bottle holder 300, the side of the linkage assembly 20 forms a spider web-like structure, which can prevent items at the bottle holder 300 from falling off the side.

[0066] As a specific embodiment of the present invention, the second connecting rod 22 of this embodiment may include two connecting rod elements 222 provided with at least one second groove 223. After the two connecting rod elements 222 snap together with one side of the side provided with the second groove 223, the corresponding two second grooves 223 overlap each other to form a through hole 224.

[0067] Specifically, the number of second grooves 223 at each link element 222 is the same as the number of baffles 60, and their positions also match the positions where the baffles 60 need to pass through. For example, in this embodiment, there are four baffles 60 located at the top, so there are four second grooves 223 at each link assembly 20, arranged in a row. The two link elements 222 interlock with the sides having the second grooves 223 to form a through hole 224 for the baffles 60 to pass through.

[0068] As a specific embodiment of the present invention, the refrigerator of this embodiment may further include a positioning piece 400 (e.g., Figure 2 and Figure 3 As shown, the positioning piece 400 is rotatably connected to the door liner 201 so that the positioning piece 400 can switch between a third state and a fourth state. When the positioning piece 400 is in the third state, it can fix the bottle holder 300 in the second state. When the positioning piece 400 switches from the third state to the fourth state, the bottle holder 300 is released so that it can switch from the second state to the first state.

[0069] Specifically, in this embodiment, the positioning piece 400 can be a plate-like structure rotatably connected to the door liner 201, with its rotation axis perpendicular to the rotation axis of the connecting rod assembly relative to the door liner 201. When the bottle holder 300 is retracted within the door liner 201 in the second state, the positioning piece 400 can rotate to protrude from the side of the door liner 201, thereby blocking the second connecting rod 22 and ensuring that the bottle holder 300 remains in the second state. When the bottle holder 300 needs to move from the second state to the first state, the positioning piece 400 can be rotated to retract, releasing the second connecting rod 22, allowing the connecting rod assembly 20 to move to the bottle holder 300 in the first state.

[0070] Specifically, in this embodiment, the positioning piece 400 can be a rectangular plate-like structure, with its end near one short side rotatably connected to the door liner. The third state of the positioning piece 400 is when the positioning piece 400 is rotated to a horizontal position, while the fourth state of the positioning piece 400 is when the positioning piece 400 is rotated to a vertical position. Of course, its horizontal and vertical positions are not necessarily absolutely horizontal and vertical; they can simply be states where it can block or whether the second connecting rod 22 is in place.

[0071] Specifically, in this embodiment, when the positioning piece 400 rotates to a horizontal position, a baffle 401 is also provided at the door liner 201. The baffle 401 is located on the side of the bottom position of the positioning piece 400 to prevent the positioning piece 400 from continuing to rotate when it rotates to the third state, thus fixing the connecting rod assembly 20 to the bottle holder 300 in the second state. Since the positioning piece 400 is rotatably connected to the door liner 201 in this embodiment, when it is in a horizontal position and blocks the second connecting rod 22 at the position of the door liner 201, the door liner 201 will exert an outward and downward force on the positioning piece 400. During long-term use, the positioning piece 400 may inevitably become loose. Or, in order to facilitate changing the position of the positioning piece 400, the connection between the positioning piece 400 and the door liner 201 is not tight. Therefore, it is necessary to use the baffle 401 to block the positioning piece 400 to ensure the stability of the positioning piece 400 when it fixes the connecting rod assembly 20 to the bottle holder 300 in the second state.

[0072] As a specific embodiment of the present invention, this embodiment uses the illustrations to specifically explain the operating principle of the structure of the present invention.

[0073] Specifically, a bottle holder 300 is provided, which includes two linkage assemblies 20, respectively disposed on the left and right sides of the door liner 201. Each linkage assembly 20 has a strip-shaped hole 211 at the first link 21 and a circular through hole 221 at the second link 22. The rotating shaft 31 of the limiting clamp 30 passes through the strip-shaped hole 211 and the circular through hole 221 to connect the first link 21 and the second link 22. A first support rod 41, a second support rod 42, and a third support rod 43, parallel to each other, are provided between the two linkage assemblies 20. A flexible bottom wall 10 is provided between the first support rod 41 and the second support rod 42, and a flexible side wall 50 is provided between the second support rod 42 and the third support rod 43. Multiple baffles 60 are also provided at each linkage assembly 20, forming a spider web-like side wall to prevent items located in the bottle holder 300 from falling from the side.

[0074] When the bottle holder 300 is in the first state, the first link 21 and the second link 22 of each linkage assembly 20 cross at the middle position. The rotation shaft 31 of the limiting clamp 30 passes through the circular through hole 221 and the strip hole 211 at the intersection point. Then, the limiting clamp 30 is rotated, and the boss 33 on the limiting clamp 30 is engaged with the groove 212 of the first link 21 to limit the position of the bottle holder 300 and prevent the bottle holder 300 from shaking. When the bottle holder 300 needs to switch from the first state to the second state, the boss 33 of the limiting clamp 30 is first separated from the groove 212, and then the side wall 50 is pushed towards the door liner 201. In this way, the limiting clamp 30 continuously moves in the strip hole 211 of the link, and the side wall 50 continuously moves closer to the door liner 201. When the bottle holder 300 moves to the extreme position close to the door liner 201, the positioning piece 400 is rotated to the third state. The positioning piece 400 is used to fix the second link 22 at the position of the door liner 201, thereby fixing the state of the bottle holder 300 in the second state.

[0075] When the bottle holder 300 needs to switch from the second state to the first state, the positioning piece 400 is first switched from the third state to the fourth state. At this time, the second connecting rod 22 is released, and the bottle holder 300 will move continuously under the action of gravity. The rotating shaft 31 of the limiting clamp 30 runs continuously at the strip hole 211. When it runs to the middle position of the first connecting rod 21, the boss 33 of the limiting clamp 30 and the groove 212 are engaged with each other to fix the state of the bottle holder 300 in the first state.
