DETAILED DESCRIPTION

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0040] like Figures 1 to 5 As shown, an embodiment discloses a box door structure, including a door body 100, a hook 200 and a bottle frame 300, wherein the hook 200 is movably arranged on the door body 100 so that the hook 200 can be retracted into or extended out of the door body 100, or the hook 200 is rotatably connected to the door body 100, and the bottle frame 300 is rotatably connected to the door body 100, and the bottle frame 300 is rotated relative to the door body 100 and has an initial position and a yielding position; wherein, when the bottle frame 300 rotates from the initial position to the yielding position, the hook 200 is extended out of the door body 100 as the bottle frame 300 rotates; or the hook 200 is rotated from the first position to the second position as the bottle frame 300 rotates, and the angle between the hook 200 and the door body 100 when in the second position is greater than the angle between the hook 200 and the door body 100 when in the first position.

[0041] In the above-mentioned box door structure, the bottle frame 300 can rotate relative to the door body 100 to adjust the position of the bottle frame 300, so as to facilitate the placement of larger items on one side of the door body 100. When the bottle frame 300 rotates from the initial position to the yield position relative to the door body 100, the hook 200 can move or rotate with the rotation of the bottle frame 300. At this time, the hook 200 can extend from the door body 100, or rotate from the first position to the second position relative to the door body 100, so that the angle between the hook 200 and the door body 100 is increased, that is, at this time, the hook 200 switches from a posture that is inconvenient for hanging objects to a posture that is convenient for hanging objects, and the bottle frame 300 makes way by rotating, so that the space on the door body 100 that can be used for hanging objects is larger, and items with larger length or height can be hung on the hook 200. Therefore, the above-mentioned box door structure can store items of different sizes, and the hook 200 will move or rotate with the bottle frame 300, and will not occupy extra space when not in use, making it more convenient to use.

[0042] Optionally, when the bottle frame 300 rotates, it can directly drive the hook 200 to move or rotate relative to the door body 100 through transmission cooperation; or by detecting the position change of the bottle frame 300, an output signal controls the hook 200 to move or rotate relative to the door body 100.

[0043] Optionally, there are at least two bottle frames 300 , which are vertically spaced apart on the door body 100 . By rotating all or part of the bottle frames 300 , the space on the door body 100 can be adjusted to facilitate the storage of items of different sizes.

[0044] Optionally, when the bottle frame 300 rotates from the yield position to the initial position, the hook 200 is controlled to retract into the door body 100; or the hook 200 is controlled to rotate from the second position to the first position, that is, after the bottle frame 300 returns to its original position, the hook 200 will also return to its original position, and the hook 200 will not affect at this time.

[0045] Optionally, when the hook 200 is rotatably connected to the door body 100, the angle between the hook 200 and the door body 100 ranges from 0° to 90°. When the hook 200 is in the first position, the angle between the hook 200 and the door body 100 is 0° or approximately 0°, and as the bottle frame 300 rotates, the hook 200 also rotates accordingly, and it is convenient to hang items.

[0046] Among them, Figure 4 As shown, at this time, the bottle frame 300 is in the initial position, and the hook 200 is in the first position.

[0047] In one embodiment, if Figures 1 to 4 As shown, the first end 310 of the bottle frame 300 is rotatably connected to the door body 100, and the second end 320 of the bottle frame 300 can move in a direction close to or away from the door body 100. When the bottle frame 300 is in the initial position, the bottle frame 300 is in contact with the door body 100. When the bottle frame 300 rotates from the initial position to the yield position relative to the door body 100, the second end 320 of the bottle frame 300 is away from the door body 100 and is spaced from the door body 100. When the bottle frame 300 rotates from the initial position to the yield position relative to the door body 100, the second end 320 of the bottle frame 300 rotates to be spaced from the door body 100 due to the state of being in contact with the door body 100. As the hook 200 extends from the door body 100 or rotates to increase the angle between the hook 200 and the door body 100, an object can be hung on the hook 200. At this time, the object can be longer or higher, and there is no need to worry about position interference with the bottle frame 300.

[0048] Optionally, the second end 320 of the bottle frame 300 is detachably connected to the door body 100. When there is no need to rotate the bottle frame 300, the second end 320 of the bottle frame 300 can be connected to the door body 100 to prevent the bottle frame 300 from rotating without external force. When it is necessary to rotate the bottle frame 300, the second end 320 of the bottle frame 300 can be detached from the door body 100.

[0049] In other embodiments, the rotatable connection between the bottle frame 300 and the door body 100 may also be other modes. For example, both ends of the bottle frame 300 are respectively rotatably connected to the door body 100, and the bottle frame 300 rotates relative to the door body 100 by flipping; or one end of the bottle frame 300 is rotatably connected to the door body 100, and the other end of the bottle frame 300 rotates along the door body 100. For example, when the bottle frame 300 moves from an initial position to a yield position, the bottle frame 300 rotates from being parallel to the horizontal direction to being perpendicular to the horizontal direction, and the distance between the bottle frame 300 and the door body 100 remains unchanged or changes slightly.

[0050] In one embodiment, if Figures 2 to 5 As shown, the above-mentioned door structure also includes a transmission assembly 400, and the bottle frame 300 is in transmission cooperation with the hook 200 through the transmission assembly 400. When the bottle frame 300 rotates from the initial position to the yield position, the bottle frame 300 drives the hook 200 to extend from the door body 100 through the transmission assembly 400; or the bottle frame 300 drives the hook 200 to rotate from the first position to the second position through the transmission assembly 400. At this time, the bottle frame 300 directly drives the hook 200 to move or rotate relative to the door body 100 through the transmission assembly 400, that is, the hook 200 moves with the bottle frame 300 through the mechanical transmission method, and the transmission process is simple and stable.

[0051] In one embodiment, if Figures 3 to 5 As shown, the above-mentioned door structure also includes a rotating shaft 110, the bottle frame 300 is connected to the rotating shaft 110, the rotating shaft 110 is rotatably connected to the door body 100, the hook 200 includes a hook portion 210 and a matching portion 220, the matching portion 220 is rotatably connected to the door body 100, and the transmission assembly 400 includes a transmission belt 410, the rotating shaft 110 drives the matching portion 220 to rotate through the transmission belt 410, when the bottle frame 300 rotates from the initial position to the yield position, the rotating shaft 110 drives the matching portion 220 to rotate through the transmission belt 410, so that the hook 200 rotates from the first position to the second position. The hook 200 is also rotatably connected to the door body 100, and the transmission belt 410 can drive the matching portion 220 of the hook 200 to rotate when the bottle frame 300 rotates, so that the hook 200 rotates with the bottle frame 300. The belt drive method has less noise, which can reduce noise and improve user experience.

[0052] In other embodiments, the bottle frame 300 may also drive the hook 200 to rotate relative to the door body 100 through gear transmission or chain transmission.

[0053] In other embodiments, the bottle frame 300 can also drive the hook 200 to extend from or retract into the door body 100 by rotating. For example, the door body 100 is provided with a mounting groove, the hook 200 is provided in the mounting groove and slidably cooperates with the door body 100, the hook 200 is provided with a rack, the rotating shaft 110 is provided with a driving gear, and the door body 100 is provided with a driven gear. The driving gear and the driven gear are transmission-coordinated, and the driven gear is meshed with the rack. The rotation of the driving gear can drive the rack to translate, so that the hook 200 extends from or retracts into the door body 100.

[0054] In one embodiment, if Figure 1 , Figures 3 to 5 As shown, the door body 100 includes a main board 120, a first side board 130 and a second side board 140, the first side board 130 and the second side board 140 are respectively connected to two ends of the main board 120, the first side board 130 and the second side board 140 are spaced apart, the main board 120, the first side board 130 and the second side board 140 form a receiving groove 101, the rotating shaft 110 is rotatably connected to an end of the first side board 130 away from the door body 100, the corners of the bottle frame 300 are connected to the rotating shaft 110, when the bottle frame 300 is in the initial position, the bottle frame 300 is at least partially located in the receiving groove 101, when the bottle frame 300 rotates from the initial position to the yield position, the bottle frame 300 rotates in a direction away from the receiving groove 101 and disengages from the receiving groove 101. When the bottle frame 300 is not rotated relative to the door body 100, the bottle frame 300 can be partially located in the receiving groove 101 on the door body 100, reducing the volume protruding from the door body 100. At the same time, when objects are placed on the bottle frame 300, the objects will not protrude too much from the door body 100. When the bottle frame 300 is rotated relative to the door body 100, the bottle frame 300 can be separated from the receiving groove 101, so that the space in the receiving groove 101 will not be blocked by the bottle frame 300, which is conducive to storing larger objects.

[0055] In one embodiment, if Figure 4 and Figure 5As shown, the transmission assembly 400 also includes a first pulley 420, a second pulley 430 and a third pulley 440, there are two transmission belts 410, the hook 200 is arranged on the main board 120, the first pulley 420 is sleeved outside the rotating shaft 110, the second pulley 430 is rotatably arranged at the connection between the first side plate 130 and the main board 120, and the third pulley 440 is used to drive the matching part 220 to rotate, one of the transmission belts 410 is respectively sleeved outside the first pulley 420 and the second pulley 430, and the other transmission belt 410 is respectively sleeved outside the second pulley 430 and the third pulley 440, and the two transmission belts 410 on the second pulley 430 are arranged in sequence along the axial direction of the second pulley 430. At this time, the first pulley 420, the second pulley 430 and the third pulley 440 can match the specific structure of the door body 100 to facilitate transmission. When the bottle frame 300 rotates relative to the first side plate 130, the rotating shaft 110 rotates with the bottle frame 300. At this time, the first pulley 420 on the rotating shaft 110 can drive the second pulley 430 to rotate through the transmission belt 410, and the second pulley 430 drives the third pulley 440 to rotate through another transmission belt 410, thereby making the third pulley 440 drive the hook 200 to rotate.

[0056] In one embodiment, if Figures 4 to 6 As shown, the transmission assembly 400 also includes a first gear 450, a second gear 460 and a third gear 470. The first gear 450 is connected to the third pulley 440 and is coaxially arranged. The second gear 460 is rotatably arranged on the main board 120. The third gear 470 is sleeved outside the matching portion 220. The first gear 450, the second gear 460 and the third gear 470 are meshed in sequence. Through the first gear 450, the second gear 460 and the third gear 470, the transmission ratio can be adjusted so that the hook 200 can rotate with the rotation of the bottle frame 300. At the same time, the rotation angle of the hook 200 will not be too large, ensuring that the hook 200 can be rotated to a position convenient for hanging items.

[0057] In one embodiment, if Figure 4 and Figure 5 As shown, there are multiple hooks 200, at least two of which form a hook group, and the hooks 200 in the hook group are arranged at intervals in the horizontal direction. A transmission assembly 400 is used to drive the hooks 200 in a hook group to extend from the door body 100 or rotate from the first position to the second position. At this time, the hooks 200 in a hook group are all driven by the same transmission assembly 400, which can be conveniently used.

[0058] Optionally, the number of the third pulleys 440 is set corresponding to the number of the hooks 200 .

[0059] In one embodiment, if Figure 1As shown, there are at least two bottle frames 300, and different bottle frames 300 are arranged on the door body 100 at intervals along the vertical direction, wherein two adjacent bottle frames 300 are respectively the first bottle frame and the second bottle frame, and the first bottle frame is arranged above the second bottle frame, and hooks 200 are arranged between the first bottle frame and the second bottle frame and on the side of the first bottle frame away from the second bottle frame. At this time, when the first bottle frame rotates relative to the door body 100, the space above the second bottle frame increases, which can be used to store longer or higher items, such as large bottles of beverages, etc., and after the first bottle frame or the second bottle frame rotates relative to the door body 100, longer items can be hung on the hooks 200, and there is no need to worry about position interference with the first bottle frame or the second bottle frame, which is more convenient to use.

[0060] Optionally, all the bottle frames 300 are connected to the same rotating shaft 110; or there are multiple rotating shafts 110 and they are arranged one-to-one with the bottle frames 300, there are multiple transmission assemblies 400, and the transmission assemblies 400 are arranged one-to-one with the bottle frames 300. In this case, after a bottle frame 300 rotates relative to the door body 100, the corresponding hook 200 can be driven to rotate through the corresponding transmission assembly 400.

[0061] In another embodiment, the box door structure further includes a proximity switch and a motor. The proximity switch is disposed on the door body 100 and is used to sense the bottle frame 300. The proximity switch is electrically connected to the motor, and the motor is used to drive the hook 200 to move or rotate relative to the door body 100. When the proximity switch senses that the bottle frame 300 rotates from the initial position to the yield position, the proximity switch outputs a control signal to the motor.

[0062] The motor is controlled to drive the hook 200 to extend from the door body 100;

[0063] Or the motor is controlled to drive the hook 200 to rotate from the first position to the second position.

[0064] At this time, the proximity switch can be used to detect the position of the bottle frame 300. When the proximity switch senses that the bottle frame 300 rotates from the initial position to the yield position, the proximity switch can output a control signal to the motor, so that the motor drives the hook 200 to extend from the door body 100 or rotate relative to the door body 100.

[0065] In other embodiments, when the bottle frame 300 is located at the initial position, the hook 200 is disposed between the door body 100 and the bottle frame 300. When the bottle frame 300 does not rotate relative to the door body 100, the hook 200 is stored between the door body 100 and the bottle frame 300, and when the bottle frame 300 rotates relative to the door body 100 and leaves the initial position, the hook 200 can extend out of the door body 100 or rotate relative to the door body 100 for hanging items, and when the bottle frame 300 returns to the initial position, the hook 200 will be blocked by the bottle frame 300, the hook 200 will not affect the use of the bottle frame 300, and the overall appearance of the door body 100 is better.

[0066] In one embodiment, if Figure 5 As shown, when the hook 200 is rotatably connected to the door body 100, a groove 102 is provided on the door body 100, and when the bottle frame 300 is located at the initial position, the hook 200 is located at the first position and is provided in the groove 102, and when the bottle frame 300 rotates from the initial position to the yield position, the hook 200 rotates from the first position to the second position and rotates out of the groove 102. At this time, if the bottle frame 300 is located at the initial position, the hook 200 is located in the groove 102, does not protrude from the door body 100, and does not interfere with the position of the bottle frame 300 or the items placed on the bottle frame 300.

[0067] Optionally, the transmission assembly 400 may be disposed inside the door body 100 or at an end of the door body 100 to reduce the impact on the overall appearance of the door body 100 .

[0068] Optionally, an adapter hole is provided on the door body 100, and the rotating shaft 110 passes through the adapter hole and can rotate in the adapter hole. The outer diameter of the rotating shaft 110 is greater than or equal to the aperture of the adapter hole. At this time, there is a certain friction between the rotating shaft 110 and the inner wall of the adapter hole when the rotating shaft 110 rotates, and a certain force needs to be applied to rotate the bottle frame 300 relative to the door body 100. At the same time, after the rotation, due to the friction between the rotating shaft 110 and the inner wall of the adapter hole, the bottle frame 300 will be positioned and will not rotate at will.

[0069] like Figures 1 to 3 As shown, an embodiment discloses a refrigerator, including a cabinet 500 and a cabinet door structure as in any of the above embodiments, wherein the door 100 is rotatably connected to the cabinet 500.

[0070] In the above-mentioned refrigerator, the bottle frame 300 can be rotated relative to the door body 100 to adjust the position of the bottle frame 300, so as to facilitate the placement of larger items on one side of the door body 100. When the bottle frame 300 is rotated from the initial position to the yield position relative to the door body 100, the hook 200 can move or rotate with the rotation of the bottle frame 300. At this time, the hook 200 can be extended from the door body 100, or rotated from the first position to the second position relative to the door body 100, so that the angle between the hook 200 and the door body 100 is increased, that is, at this time, the hook 200 is switched from a posture that is inconvenient for hanging objects to a posture that is convenient for hanging objects, and the bottle frame 300 makes way by rotating, so that the space on the door body 100 that can be used for hanging objects is larger, and items with larger length or height can be hung on the hook 200. Therefore, the above-mentioned door structure can store items of different sizes, and the hook 200 will move or rotate with the bottle frame 300, and will not occupy extra space when not in use, making it more convenient to use.

[0071] In one embodiment, a shelf 510 is provided in the box body 500. When the bottle frame 300 is in the yield position and the door body 100 is in the closed state, the bottle frame 300 extends into the box body 500, and the bottle frame 300 is spaced apart from the shelf 510. At this time, after the bottle frame 300 rotates and is spaced apart from the door body 100, it will extend into the space in the box body 500. At this time, the bottle frame 300 is spaced apart from the shelf 510, and no position interference occurs.

[0072] Specifically, when the bottle frame 300 extends into the box body 500 , the bottle frame 300 and the shelf 510 are arranged vertically spaced apart.

[0073] Optionally, the refrigerator can be a double-door refrigerator or a single-door refrigerator.
