[0064] First embodiment

[0065] like Figure 1-Figure 3 As shown, a refrigerator door can be installed in a refrigerator to achieve a closed state of the refrigerator, isolate it from the outside, and meet the refrigeration needs.

[0066] The refrigerator door, for example, includes a door body 1 located in a refrigerated area, at least one bottle frame 2, a guide structure 3, and a tightening structure 4. Among them, the bottle frames 2, for example, can be two, three, or four, and the multiple bottle frames 2 are arranged in sequence along the vertical direction, depending on the actual situation. The bottle frame 2 can be used to store items, so as to make full use of the refrigerator door and improve space utilization.

[0067] For example, two guide structures 3 may be provided, and the two guide structures 3 are symmetrically arranged on the door body 1 along the vertical direction, and the bottle frame 2 is located between the two guide structures 2 to improve the overall stability of the bottle frame 2. The bottle frame 2 moves or is fixed on the guide structure 3 through the tightening structure 4 to achieve adjustment or locking of the bottle frame 2, so that the bottle frame 2 has an adjustment state or a locking state.

[0068] Two tightening structures 4 can be provided correspondingly, and the tightening structures 4 correspond to the guide structures 3 one by one, so that the bottle frame 2 can be connected to the corresponding guide structure 3 through the tightening structure 4, and the tightening structure 4 includes a driving mechanism 41 and a tightening mechanism 42, and the driving mechanism 41 is respectively connected to the bottle frame 2 and the tightening mechanism 42. Among them, the bottle frame 2 has an adjustment state and a locking state.

[0069] When the bottle frame is switched from the locked state to the adjusted state, the bottle frame 2 is lifted toward the direction close to the door body 1, and the bottle frame 2 drives the driving mechanism 41 to move, and the driving mechanism 41 drives the pressing mechanism 42 to move, so that a gap is generated between the pressing mechanism 42 and the guide structure 3, forming a separation setting. At this time, the position of the bottle frame 2 can be adjusted upward or downward so that the bottle frame 2 is at a target height, which is convenient for storing items.

[0070] When the bottle frame 2 is switched from the adjustment state to the locking state, the bottle frame 2 is pressed downward in the direction away from the door body 1, and the bottle frame 2 drives the driving mechanism 41 to move, and the driving mechanism 41 drives the pressing mechanism 42 to move, so that the pressing mechanism 42 and the guide structure 3 contact each other to form a counter-arrangement. At this time, the pressing mechanism 42 and the guide structure 3 resist each other to limit the further movement of the pressing mechanism 42, thereby achieving locking.

[0071] Among them, the bottle frame 2 can be flipped relative to the door body 1 under the action of external force to switch the bottle frame 2 to the adjustment state or the locking state. For example, when the bottle frame 2 is in the adjustment state, the user applies force to the bottle frame 2, lifts the bottle frame 2 upward, so that the bottle frame 2 flips relative to the door body 1, that is, flips upward in the direction of the door body 1. At this time, a first angle α is formed between the bottle frame 2 and the door body 1, and the first angle α is, for example, 0°-60°. When the bottle frame 2 is in the locking state, the user applies force to the bottle frame 2, presses the bottle frame 2 downward, so that the bottle frame 2 flips relative to the door body 1, that is, flips downward in the direction of the door body 1. At this time, there is a second angle β between the bottle frame 2 and the door body, wherein the second angle β is greater than the first angle α, and the second angle β is, for example, 85°-100°. The bottle frame 2 is connected to the driving mechanism 41 to drive the driving mechanism 41 to rotate, and the bottle frame 2 is used to apply external force to achieve position adjustment. The user can apply force at any position of the bottle frame 2, which is highly flexible and improves the user experience. Alternatively, a handle (not shown in the figure) may be provided on the bottle frame 2 to provide a position for the user to apply force and avoid damaging the bottle frame 2 .

[0072] In this embodiment, if Figure 3 , Figure 4 As shown, each clamping mechanism 42 includes a locking unit, and the driving mechanism 42 drives the locking unit to move relative to the guide structure 3, so that the locking unit clamps the guide structure 3 or releases the guide structure 3, so as to achieve locking or adjustment of the bottle frame 2 to meet user needs.

[0073] The locking unit includes two pressing parts 421 , which are symmetrically arranged along the vertical direction. Part of the structure of the driving mechanism 41 is sandwiched between the two pressing parts 421 , and the driving mechanism 41 rotates relative to the pressing parts 421 .

[0074] The tightening portion 421 is located in the guide structure 3, and when the bottle frame 2 is switched from the adjustment state to the locking state, the driving mechanism 41 rotates relative to the tightening portion 421 to drive the two tightening portions 421 to move in opposite directions, and the tightening portion 421 abuts against the guide structure 3 to limit further movement of the tightening portion 421.

[0075] When the bottle frame 2 switches from the locked state to the adjusted state, the driving mechanism 41 rotates relative to the tightening part 421 to drive the two tightening parts 421 to move toward each other, and the tightening parts 421 withdraw from the guide structure 3, so that a gap is formed between the tightening parts 421 and the guide structure 3, which facilitates the adjustment of the position of the tightening parts 421.

[0076] In this embodiment, if Figure 3 , Figure 4 As shown, the tightening portion 421 includes a tightening block 4211 and a driving rack 4212 disposed on the tightening block 4211. The tightening block 4211 and the driving rack 4212 are an integrally formed structure, which has good strength and improves reliability during connection. The tightening block 4211 is meshed and connected with the driving mechanism 41 through the driving rack 4212, wherein the driving mechanism 41 includes, for example, a driving gear 412, and the driving gear 412 is meshed and connected with the driving rack 4212 to facilitate linear drive.

[0077] In this embodiment, if Figure 3 , Figure 4 As shown, each tightening portion 421 includes an abutment block 4213 arranged on the tightening block 4211, and the abutment block 4213 is arranged on a side of the tightening block 4211 close to the guide structure 3, and the abutment block 4213 is detachably connected to the tightening block 4211.

[0078] When the adjustment device is in the locked state, the abutment block 4213 abuts against the guide structure 3. The tightening block 4211 is, for example, a cuboid to increase the contact area with the guide structure 3, ensure stability during abutment, and provide sufficient friction surface and friction force.

[0079] First example

[0080] The abutment block 4213 is directly attached to the surface of the tightening block 4211 to simplify the installation method and make it easy to implement. The abutment block 4213 is, for example, bonded to the tightening block 4211 to facilitate assembly and improve assembly efficiency. The abutment block 4213 is, for example, a rubber friction pad to increase the friction between the abutment block 4213 and the guide structure 3.

[0081] Second example

[0082] The difference from the first example is that the pressing block 4211 is provided with a first groove 42111, and the abutting block 4213 can be buried in the first groove 42111 to achieve the installation of the abutting block 4213. The size of the abutting block 4213 can match the size of the first groove 42111, such as interference fit, to ensure the reliability of the abutting block 4213 during installation and prevent it from falling off. The surface of the abutting block 4213 protrudes from the edge of the first groove 42111 to ensure that the abutting block 4213 can abut against the guide structure 3.

[0083] Third Example

[0084] The difference from the first example or the second example is that the top tightening block 4211 is provided with a mounting blind hole 42112, and the abutting block 4213 is provided with a mounting column 42131, so that when the abutting block 4213 is installed to the top tightening block 4211, its mounting column 42131 is plugged and connected with the mounting blind hole 42112, so as to further improve the reliability of the connection. It is understandable that the number of the above-mentioned mounting blind holes 42112 and mounting columns 42131 can be 1, 2, or more, etc., which shall be subject to the actual situation.

[0085] In this embodiment, if Figure 3-Figure 5 As shown, the driving mechanism 41 includes a bottle frame mounting seat 411 and a driving gear 412, and the driving gear 412 is meshed and connected with a driving rack 4212 to facilitate the linear movement of the driving rack 4212. The bottle frame mounting seat 411 is detachably connected to the bottle frame 2, for example, a limiting block 413 is provided on the side of the bottle frame mounting seat 411 away from the driving gear 412, and a limiting groove 21 is provided on the bottle frame 2. The bottle frame mounting seat 411 is plugged or slidably connected with the bottle frame 2 through the limiting block 413, wherein the limiting block 413 is, for example, T-shaped and slidably connected with the limiting groove 21 to prevent the bottle frame 2 from falling off.

[0086] The driving gear 412 is fixedly connected to the bottle frame mounting seat 411, and the reliability of the connection is improved. When the driving force is applied to the driving gear 412 through the bottle frame mounting seat 411, the driving gear 412 can stably drive the driving rack 4212 without loosening or falling off.

[0087] In this embodiment, if Figure 3-Figure 5As shown, a shielding plate 414 is provided on the side of the bottle frame mounting seat 411 away from the driving gear 412, and the shielding plate 414 is provided to shield at least part of the bottle frame 2. The shielding plate 414 is, for example, L-shaped, connected to the side of the bottle frame mounting seat 411, and located on one side of the door body 1. When the bottle frame 2 is installed, the shielding plate 414 can wrap around the corners of the bottle frame 2 to protect it and avoid collision with the door body 1 and damage. The corners of the shielding plate 414 can be rounded to fit the bottle frame 2 and avoid collision with the door body 1, so as to ensure that the door body 1 will not be damaged.

[0088] In this embodiment, if Figure 3-Figure 5 , Figure 8 , Fig.10 As shown, the tightening structure 4 includes two sliding mechanisms 43, which are symmetrically arranged on both sides of the tightening mechanism 42 in the horizontal direction, and the sliding mechanisms 43 abut against the guide structure 3, and the sliding mechanisms 43 can generate relative motion with the guide structure 3. When adjusting the position of the bottle frame 2, the sliding mechanisms 43 can reduce the resistance, so that the bottle frame 2 can be adjusted up and down more smoothly, thereby improving the user experience.

[0089] In this embodiment, if Figure 3-Figure 5 , Figure 8 , Fig.10 As shown, the sliding mechanism 43 includes an elastic member 431 , two sliding rollers 432 and two roller mounting seats 433 .

[0090] The two roller mounting seats 433 are connected by an elastic member 431, and the sliding roller 432 is mounted on the corresponding roller mounting seat 433, and the sliding roller 432 can move on the guide structure 3. The elastic member 431 is, for example, a preloaded spring, and the elastic member 431 can push the roller mounting seats 433 to move in opposite directions, so that the sliding roller 432 is always in contact with the guide structure 3.

[0091] The roller mounting seat 433 includes, for example, a fixed pile 4331, a roller cover 4332 and a sliding rod 4333. The fixed pile 4331 is fixedly connected to the roller cover 4332, and a part of the structure of the fixed pile 4331 is located inside the roller cover 4332, so that the sliding roller 432 can be rotatably sleeved on the fixed pile 4331. The sliding rod 4333 is arranged on the radial outer side wall of the roller cover 4332, and the sliding rod 4333 is slidably connected to the top tightening structure 4, so as to limit the movement path of the roller mounting seat 433, and ensure that it moves linearly in the horizontal direction. Among them, a gap is set between the sliding roller 432 and the roller cover 4332 to ensure that the sliding roller 432 can rotate normally.

[0092] In this embodiment, if Figure 3-Figure 7As shown, the tightening structure 4 further includes a tightening mounting seat 44, which is provided with an accommodation space 444, in which the tightening portion 421 of the tightening mechanism 42 and the sliding mechanism 43 are both installed to ensure the integrity of the appearance and avoid the structure being exposed, which would affect its use effect or safety. Among them, the inner side wall of the accommodation space 444 is provided with a slide groove 4441, and the sliding rod 4333 is slidably connected with the slide groove 4441.

[0093] The tightening mounting seat 44 is provided with a plurality of avoidance holes 445 communicating with the accommodating space 444, and can also constrain the tightening portion 421 and the sliding mechanism 43 to move in a predetermined direction. Part of the structure of the tightening mechanism 42 can pass through the avoidance holes 445 to abut against the guide structure 3.

[0094] In some examples, the avoidance through hole 445 includes two first avoidance through holes 4451 , which penetrate the side wall of the pressing mounting seat 44 . The pressing portion 421 can pass through the corresponding first avoidance through holes 4451 and abut against the guide structure 3 .

[0095] In some other examples, the avoidance through hole 445 includes a plurality of second avoidance through holes 4452 that penetrate the side wall of the pressing mounting seat 44. The sliding rollers 432 of the two sliding mechanisms 43 can pass through the corresponding second avoidance through holes 4452 and abut against the guide structure 3.

[0096] In this embodiment, if Figure 3-Figure 7 As shown, the top-tightening mounting seat 44 includes a mounting base 441 and a mounting cover 442. The accommodating space 444 and the avoidance through hole 445 are both formed in the mounting base 441. The mounting cover 442 is buckled to the mounting base 441 to close the accommodating space 444, shielding it and preventing the interior from being exposed. The mounting cover 442 is, for example, embedded in the mounting base 441 for easy assembly and disassembly.

[0097] The mounting cover plate 442 is provided with a mounting through hole 4421 , through which the driving gear 412 of the driving mechanism 41 can pass, and be connected to the mounting base 441 .

[0098] In this embodiment, if Figure 3-Figure 7 As shown, the mounting cover plate 442 is provided with a limiting ring 4422 along the circumference of the mounting through hole 4421 , and the limiting ring 4422 is provided with an avoidance notch 4423 , and the driving gear 412 of the driving mechanism 41 passes through the mounting through hole 4421 through the avoidance notch 4423 and is connected to the mounting base 441 .

[0099] Among them, the bottle frame mounting seat 411 can be provided with a hook 415, for example, which can enter the accommodating space 444 through the avoidance notch 4423, and drive the driving gear 412 to rotate relative to the mounting cover 442, so that the hook 415 on the bottle frame mounting seat 411 is staggered with the avoidance notch 4423, and the hook 415 and the limiting ring 4422 are limitedly connected to limit the movement of the driving mechanism 41 along its axial direction, thereby ensuring that the driving mechanism 41 will not separate from the pressing mounting seat 44.

[0100] In this embodiment, if Figure 3-Figure 7 As shown, the mounting cover plate 442 is provided with a mounting through hole 4421, the mounting base 441 is provided with a limiting shaft 4411, and the driving gear 412 passes through the mounting through hole 4421 and is connected to the limiting shaft 4411, thereby realizing the installation of the driving gear 412. The driving gear 412 is provided with a mounting hole 4121, and the driving gear 412 is plugged into the limiting shaft 4411 through the mounting hole 4121, so that the driving gear 412 can rotate around the limiting shaft 4411, thereby improving the reliability of the driving gear 412 when rotating.

[0101] In this embodiment, if Figure 3-Figure 7 As shown, the tightening mounting seat 44 includes a plurality of bearing plates 443 disposed on a mounting base 441 , and the tightening mechanisms 42 are disposed on corresponding bearing plates 443 .

[0102] In some examples, the bearing plate 443 includes two pairs of first bearing plates 4431, and the two first bearing plates 4431 are symmetrically arranged. The pressing portion 421 is sandwiched between the two first bearing plates 4431 located on the same side, and the first bearing plates 4431 can support the pressing portion 421 and limit the movement direction of the pressing portion 421 to ensure that the pressing portion 421 can move in the horizontal direction.

[0103] In some other examples, the bearing plate 443 includes a plurality of second bearing plates 4432, and the plurality of second bearing plates 4432 are arranged together in intervals of two. A slide groove 4441 is configured between two adjacent second bearing plates 4432 to limit the movement direction of the sliding mechanism 43. The second bearing plates 4432 can be arranged on the mounting base 441 and the mounting cover plate 442 to ensure stable sliding of the sliding mechanism 43.

[0104] It should be noted that the above-mentioned mounting base 441 and mounting cover plate 442 may also be provided with reinforcing ribs 446 to enhance the strength of the mounting base 441 and mounting cover plate 442 and extend their service life.

[0105] In this embodiment, if Figure 2As shown, the guide structure 3 includes a guide rail 31 and a blocking member 32. A blocking member 32 is provided at both ends of the guide rail 31 to shield and block the end of the guide rail 31 to prevent the tightening structure 4 from falling out of the guide rail 31. The guide rail 31 is attached to the door body 1, for example, by bonding, screwing, etc.

[0106] Among them, the distance between the guide rail 31 of the guide structure 3 and the inner wall is greater than or equal to the distance between the outer edges of the tightening parts 421 of the two tightening mechanisms 42, so as to ensure that when the tightening parts 421 abut against the guide rail 31 of the guide structure 3, a larger force can be provided to achieve tightening.

[0107] The guide rail 31 includes a first connecting plate 311 and two abutting plates 312, and the two abutting plates 312 are arranged on both sides of the first connecting plate 311. The first connecting plate 311 and the two abutting plates 312 are an integrally formed structure to improve the reliability of the connection of the guide rail 31. The first connecting plate 311 and the two abutting plates 312 form a U-shaped structure to accommodate the tightening mechanism 42.

[0108] The tightening block 4211 of the tightening mechanism 42 can abut against the abutting plate 312 to facilitate fixation, or the tightening block 4211 can retreat from the abutting plate 312 to facilitate adjustment of the position of the bottle frame 2 to meet the needs of users.

[0109] The refrigerator door proposed in this embodiment utilizes the opening or contraction of the tightening mechanism to complete the adjustment and fixation of the bottle frame. Its tightening block abuts against the guide structure, and the adjustment is simple and easy to operate, which effectively improves the user experience when using it.

[0110] Second embodiment

[0111] The second embodiment of the present application also provides a refrigerator door, which has the same or similar structure as the refrigerator door provided in the first embodiment, except that the guide structure 3 and the tightening portion 421 in the tightening mechanism 42 in this embodiment are different. The guide structure 3 and the tightening portion 421 are further explained below.

[0112] like Figure 3-Figure 7 , Fig.10 As shown, the tightening portion 421 in this embodiment includes a tightening block 4211, a driving rack 4212, an abutment block 4213 and a clamping block 4214. The connection method between the tightening block 4211 and the driving rack 4212 is the same as that in the first embodiment mentioned above, and will not be repeated here.

[0113] The clamping block 4214 is fixedly connected to the tightening block 4211 , and the clamping block 4214 is located on a side of the tightening block 4211 close to the guide structure 3 , so as to achieve a clamping connection with the guide structure 3 .

[0114] Exemplarily, the guide rail 31 includes a second connecting plate 313 and a clamping plate 314, the second connecting plate 313 is fixedly connected to the clamping plate 314, and the clamping plate 314 is, for example, located in the middle of the second connecting plate 313, so that the guide rail 31 forms a C-shaped structure. The two clamping blocks 4214 of the clamping mechanism 42 are located on both sides of the clamping plate 314, so that the clamping blocks 4214 and the clamping plate 314 are clamped and connected.

[0115] When the adjusting device is in the adjusting state, the driving mechanism 41 drives the clamping blocks 4214 of the two tightening parts 421 to move in opposite directions, and the clamping blocks 4214 withdraw from the clamping plates 314 of the guide structure 3, so that a gap is formed between the clamping blocks 4214 of the tightening parts 421 and the clamping plates 314 of the guide structure 3, which facilitates the adjustment of the position of the tightening parts 421.

[0116] When the adjusting device is in the locked state, the driving mechanism 41 drives the clamping blocks 4214 of the two pressing parts 421 to move toward each other, and the clamping blocks 4214 of the pressing parts 421 clamp the clamping plate 314 of the guide structure 3 to achieve fixation.

[0117] In this embodiment, if Figure 3-Figure 7 , Fig.10 As shown, the clamping block 4214 is, for example, a cuboid, so as to increase the contact area with the clamping plate 314 of the guide structure 3, ensure stability during clamping, and provide sufficient friction surface and friction force.

[0118] Abutment block 4213 may be provided on one side of clamping block 4214 close to clamping plate 314 to increase friction and improve stability during clamping. Abutment block 4213 and clamping block 4214 are detachably connected to facilitate replacement of abutment block 4213. The specific implementation of abutment block 4213 and clamping block 4214 is the same or similar to the specific implementation of tightening block 4211 and abutment block 4213, and will not be repeated here.

[0119] The refrigerator door proposed in this embodiment is fixed by clamping, and the implementation method of the guide structure is changed. A clamping plate is added, which can improve the strength of the guide structure and extend the service life of the guide structure.

[0120] The present application also provides a refrigerator, including a refrigerator door as in any of the above embodiments. The driving mechanism drives the tightening mechanism to open or contract the tightening mechanism, complete the adjustment and fixation of the bottle frame, and ensure that the bottle frame can be adjusted horizontally up and down and fixed at any position. When adjusting the bottle frame, its sliding mechanism can contact the guide rail to reduce resistance to ensure smoothness when adjusting up and down, improve the space utilization of the door body, and improve the user experience when using it. By replacing tightening parts of different sizes and widths, the versatility of the bottle frame on door bodies of different widths is improved.
