[0038] ​​​​​​When the user needs to open the box door 2 to take or put the articles, the box door 2 provided with the turnover beam 3 is pulled, since the pivot 31 is fixedly connected with the box door 2, the rotation of the box door 2 can make the guide piece 32 rotate relative to the pivot 31 and move upward, so that the turnover beam 3 is switched to the state (i.e. the second state) perpendicular to the box door 2, the opening of the box door 2 is realized, at the same time, the turnover beam 3 avoids blocking the user's view, the opened space is more spacious, so that the user can easily take or put the articles, and in the process of taking or putting the articles, the turnover beam 3 will not be damaged due to being accidentally touched by the user.

[0039] When the box door 2 is closed, the box door 2 provided with the turnover beam 3 is pushed, since the pivot 31 is fixedly connected with the box door 2, the rotation of the box door 2 can make the guide piece 32 rotate relative to the pivot 31 and move downward, so that the turnover beam 3 is switched to the state (i.e. the first state) parallel to the box door 2, the closing of the box door 2 is realized, the turnover beam 3 can separate the gap between the two box doors 2 from the outside, so that the hot air outside enters the inside of the refrigerator 100 through the gap, and the heat insulation effect is achieved.

[0040] In addition, the pivot connection mode of the guide piece 32 and the pivot 31 makes the turnover beam 3 be able to be smoothly switched between the first state and the second state, in the process of switching the turnover beam 3 from the first state (parallel to the box door 2) to the second state (perpendicular to the box door 2), the guide piece 32 rotates relative to the pivot 31 and moves upward; in the process of switching the turnover beam 3 from the second state to the first state, the guide piece 32 rotates relative to the pivot 31 and moves downward. In this way, the movement track of the turnover beam 3 can be accurately controlled, the turnover beam 3 can be accurately switched to the second state, the situation that the box door 2 cannot be opened or closed due to the rotation of the turnover beam 3 caused by the user's accidental touch is prevented, and the working reliability of the turnover beam 3 is ensured. Moreover, the user does not need to manually rotate the turnover beam 3 to be parallel to the box door 2 and then close the box door 2, so that the operation of the user is more convenient, and the use experience of the user is improved.

[0041] According to the refrigerator 100, the turnover beam 3 on the box door 2 comprises the pivot 31 and the guide piece 32, the pivot 31 is connected with the box door 2, and the guide piece 32 is pivotally connected with the pivot 31, the setting of the turnover beam 3 ensures the heat preservation performance of the refrigerator 100, prevents the situation that the box door 2 cannot be closed due to the rotation of the turnover beam 3 caused by the user's accidental touch, ensures the working reliability of the turnover beam 3, makes the operation of the user more convenient, and improves the use experience of the user.

[0042] According to some embodiments of the present application, as Figures 3-10As shown, the rotating shaft 31 comprises a first shaft segment 311 and a second shaft segment 312 connected with each other, the first shaft segment 311 extends along a third direction, the second shaft segment 312 extends along a second direction and is connected with the box door 2, the third direction, the second direction and the first direction are perpendicular to each other. The guide 32 comprises a first guide segment 321 and a second guide segment 322 connected with each other, the first guide segment 321 extends along the third direction, the second guide segment 322 extends along the second direction, and the first guide segment 321 is threadedly connected with the first shaft segment 311.

[0043] With reference to Figure 10 , along the third direction, a plurality of cylinders with different diameters are connected in sequence to form the first shaft segment 311 (for example, the number of cylinders is three in Figure 10 ), wherein the cylinder located at the middle position has the smallest diameter, one of the two cylinders located at the end portions is formed with an internal thread, and the other cylinder is connected with the second shaft segment 312. The second shaft segment 312 can comprise a connecting portion and a sheet structure, two ends of the connecting portion are connected with the above-mentioned other cylinder and the sheet structure respectively, and the sheet structure is fixedly connected with the side wall of the box door 2.

[0044] The first guide segment 321 is substantially in the form of a cylindrical rod, and an external thread is formed on the first guide segment 321 at a position close to the first shaft segment 311, so that the first guide segment 321 is threadedly connected with the first shaft segment 311, and an end of the first guide segment 321 away from the first shaft segment 311 is connected with the second guide segment 322, and the second guide segment 322 is substantially in the form of an irregular sheet structure.

[0045] In this way, the second shaft segment 312 extends along the second direction and is connected with the box door 2, thereby providing stable support for the rotating shaft 31, the first shaft segment 311 extends along the third direction, and the first guide segment 321 is threadedly connected with the first shaft segment 311, so that the rotating movement of the turnover beam 3 around the box door 2 can be converted into the up-and-down linear movement of the first guide segment 321 along the third direction, thereby making the movement trajectory of the guide 32 more accurate. Moreover, the connection mode of thread connection can prevent the first guide segment 321 from deviating or shaking during the linear movement along the third direction, thereby further ensuring the stable switching of the turnover beam 3 between the first state and the second state.

[0046] Furthermore, as shown in Figures 3-9 , the turnover beam 3 comprises a turnover beam body 33 and a torsional spring 34.

[0047] Specifically, the turnover beam body 33 extends along the third direction, and the turnover beam body 33 has a receiving cavity 331, and the first guide segment 321 and the first shaft segment 311 are located in the receiving cavity 331. One end of the torsional spring 34 is connected with the first shaft segment 311, and the other end of the torsional spring 34 is connected with the inner wall of the turnover beam body 33.

[0048] With reference toFigure 4 The torsion spring 34 is connected to the cylinder at the end of the first shaft segment 311. When the turnover beam 3 switches between the first state (parallel to the cabinet door 2) and the second state (perpendicular to the cabinet door 2), the rotation of the cabinet door 2 can make the first guide segment 321 move upward relative to the first shaft segment 311. By connecting the two ends of the torsion spring 34 to the first shaft segment 311 and the inner wall of the turnover beam body 33, the torsion force generated by the torsion spring 34 acts on the first shaft segment 311, which is beneficial to the stability of the relative position between the first shaft segment 311 and the turnover beam body 33, making the rotation of the guide 3 more reliable, and at the same time avoiding the shift of the rotating shaft 31 in the accommodating cavity 331, ensuring the stability of the overall structure of the turnover beam 3.

[0049] In addition, the torsion spring 34 and the first guide segment 321 are respectively arranged at the two ends of the first shaft segment 311, which can make the relative movement of the first shaft segment 311 and the first guide segment 321 more stable, the stress distribution more uniform, prevent the first shaft segment 311 and the first guide segment 321 from being stuck during relative movement, reduce the wear of the first shaft segment 311 and the first guide segment 321, and prolong the service life of the turnover beam 3.

[0050] In some optional embodiments, as shown in Figure 6 The turnover beam body 33 includes a first beam body 332 and a second beam body 333.

[0051] The second beam body 333 is arranged on one side of the first beam body 332 in the first direction, and the second beam body 333 and the first beam body 332 jointly define the accommodating cavity 331. At least one first guide groove 3321 is formed on one of the second guide segment 322 and the first beam body 332, the first guide groove 3321 extends along the third direction, and at least one first guide column 3221 is arranged on the other of the second guide segment 322 and the first beam body 332, the first guide column 3221 is slidably arranged in the first guide groove 3321.

[0052] For example, in the example of Figures 3-10 Two first guide columns 3221 are arranged on the second guide segment 322, and two first guide grooves 3321 are correspondingly formed on the first beam body 332.

[0053] Alternatively, a first guide groove is formed on the second guide segment 322, and a first guide column is arranged on the first beam body 332 (not shown in the figure).

[0054] The first beam body 332 and the second beam body 333 are arranged along the first direction, can better bear external collision force, effectively prevent the turnover beam 3 from being deformed, and ensure the structural integrity of the turnover beam body 33. In the process of switching the turnover beam 3 between the first state and the second state, the cooperation mode of the first guide column 3221 and the first guide groove 3321 can limit the movement track of the second guide section 322, prevent the case that the box door 2 cannot be normally closed or opened due to the deviation or shaking of the second guide 32, and further enhance the working reliability of the turnover beam body 33.

[0055] In addition, in the assembly, the first shaft section 311 is connected with the first guide section 321, the rotating shaft 31 and the guide 32 are connected as a whole, then the first guide column 3221 and the first guide groove 3321 are matched to assemble the above-mentioned whole on the first beam body 332, and then the second beam body 333 is combined with the first beam body 332 to form the containing cavity 331, so that the assembly difficulty is smaller, and the assembly efficiency is improved.

[0056] Further, at least one second guide groove 3331 is formed on one of the second guide section 322 and the second beam body 333, the second guide groove 3331 extends along the third direction, and at least one second guide column 3222 is arranged on the other of the second guide section 322 and the second beam body 333, the second guide column 3222 is slidably arranged in the second guide groove 3331.

[0057] For example, in the example of Figures 3-10 , two second guide columns 3222 are arranged on the second guide section 322, and two second guide grooves 3331 are correspondingly arranged on the second beam body 333, the second guide grooves 3331 are substantially rectangular, and the two second guide grooves 3331 are arranged in parallel with the third direction.

[0058] Alternatively, a second guide groove is formed on the second guide section 322, and a second guide column is arranged on the second beam body 333 (not shown in the figure).

[0059] In the process of switching the turnover beam 3 between the first state and the second state, the second guide column 3222 and the first guide column 3221 jointly limit the movement track of the second guide section 322, further ensure the accuracy of the movement of the guide 32, and further ensure the working reliability of the turnover beam body 33. In addition, when the turnover beam 3 is subjected to external force during movement, the second guide column 3222 is limited in the second guide groove 3331, can share part of the stress, avoids damage of the turnover beam 3 due to local stress concentration, and prolongs the service life of the turnover beam 3.

[0060] According to some embodiments of the utility model, such as Figure 8 and Figure 10As shown, the second guiding section 322 has a connecting column 3223 extending in the third direction. The turnover beam 3 further comprises an elastic member 35 sleeved on the connecting column 3223, and one end of the elastic member 35 is abutted against the inner wall of the turnover beam body 33.

[0061] With reference to Figure 8 and Figure 10 , the connecting column 3223 has a cylindrical structure, the inner wall of the second beam body 333 is provided with a connecting plate 3332, the connecting plate 3332 is provided with a mounting hole, and the end of the elastic member 35 away from the connecting column 3223 is arranged in the mounting hole.

[0062] When the turnover beam 3 is switched from the first state to the second state, the second guiding section 322 moves upward, the elastic member 35 is stretched under force, the elastic member 35 limits the guiding member 32, avoiding the guiding member 32 from being completely separated from the turnover beam body 33 and causing the failure of the guiding member 32; when the turnover beam 3 is switched from the second state to the first state, the second guiding section 322 moves downward, the elastic member 35 is compressed under force and stores energy, and when the second guiding section 322 moves upward again, the elastic member 35 releases the energy, so that the movement of the second guiding section 322 is more stable and smooth.

[0063] By sleeving the elastic member 35 on the connecting column 3223, the movement of the elastic member 35 in the third direction can be guided and limited, so that the movement track of the guiding member 32 is more accurate. In addition, when the turnover beam 3 is switched between states, that is, when the box door 2 is quickly opened or closed, a large impact force may be generated on the turnover beam 3, and the elastic member 35 can buffer part of the impact force, thereby reducing the noise generated during the movement of the turnover beam 3.

[0064] In specific implementation, the elastic member 35 can be a spring member, but is not limited thereto.

[0065] In some optional embodiments, as shown in Figure 9 , the turnover beam 3 further comprises a heat preservation layer 36 and a sheet metal beam 37, and the heat preservation layer 36 is arranged in the accommodating cavity 331. The sheet metal beam 37 is arranged on the side of the second beam body 333 away from the first beam body 332.

[0066] For example, in Figure 9In the example, the shape of the insulation layer 36 is adapted to the shape of the receiving cavity 331. By placing the insulation layer 36 inside the receiving cavity 331, the cold air inside the cabinet 1 can be effectively blocked from being conducted to the outside of the refrigerator 100 through the flip beam 3, ensuring the sealing performance of the refrigerator 100, avoiding high energy consumption of the refrigerator 100 due to cold air leakage, and helping to maintain a low-temperature environment inside the refrigerator 100. In addition, the shape of the sheet metal beam 37 is roughly adapted to the second beam 333. By placing the sheet metal beam 37 on the side of the second beam 333 away from the first beam 332, the structural strength of the flip beam 3 can be increased, effectively preventing deformation of the flip beam 3, enhancing the durability of the flip beam 3, and thus improving the service life of the refrigerator 100.

[0067] In practice, the insulation layer 36 can be insulation foam, but is not limited to this.

[0068] Specifically, such as Figure 9 As shown, the second shaft segment 312 includes a first sub-segment 3121 and a second sub-segment 3122 connected to each other. The first sub-segment 3121 extends along a third direction, and the second sub-segment 3122 extends along a second direction and is connected to the first shaft segment 311. Among them, along the direction toward the first shaft segment 311, the cross-sectional area of ​​the second sub-segment 3122 in the third direction gradually decreases.

[0069] For example, in Figure 9 In the example, the first segment 3121 is roughly a rectangular sheet structure, the second segment 3122 is located between the first segment 3121 and the first shaft segment 311, and the first segment 3121 is connected to the door 2, and the second segment 3122 is set near the end of the first segment 3121.

[0070] Along the direction towards the first shaft segment 311, the cross-sectional area of ​​the second sub-segment 3122 gradually decreases in the third direction. This arrangement allows stress to be gradually dispersed during the transmission from the first shaft segment 311 to the door 2, reducing the possibility of damage to the guide component 3 due to stress concentration and improving the structural strength and reliability of the tilting beam 3. Because the cross-sectional area of ​​the second sub-segment 3122 gradually decreases, while meeting the requirements for structural strength and stress transmission, the overall weight and material usage of the second sub-segment 3122 are reduced, which is beneficial for the lightweight design of the refrigerator 100.

[0071] Optionally, the second guide section 322 is arc-shaped, and a limiting member 11 is provided on the open side of the housing 1. The limiting member 11 is adapted to stop against the second guide section 322.

[0072] In specific implementation, such as Figures 1-10 As shown, the thickness direction of the second guide segment 322 (e.g., Figure 10The two side walls in the front-rear direction of the second guide section 322 are curved, so that the shape of the second guide section 322 is arc-shaped, and the limiting piece 11 is arranged close to the end of the box body 1, and the limiting protrusion 111 is formed on the limiting piece 11 and is matched with the shape of the second guide section 322, so that the second guide section 322 is in contact with the limiting protrusion 111 to generate an acting force, thereby moving the second guide section 322 downward, and the second guide section 322 is arc-shaped, compared with the straight line type or the angular guide block in the prior art, the second guide section 322 is more smooth in contact with the limiting protrusion 111 in the movement process, and the smooth degree of the user in opening and closing the box door 2 is improved.

[0073] In addition, the guide block and the limiting block in the prior art are prone to manufacturing errors in the manufacturing process, so that the guide block and the limiting piece cannot be matched due to position interference, and the box door 2 cannot be opened or closed. By setting the shapes of the second guide section 322 and the limiting protrusion 111 as arc-shaped, the tolerance is increased, and the problem that the box door 2 cannot be opened or closed due to the manufacturing error is avoided.

[0074] In some optional embodiments, as shown in Figures 1-9 The turnover beam 3 further comprises an intermediate shaft 38, one end of the intermediate shaft 38 is connected with one of the two adjacent box doors 2, and the other end is connected with the turnover beam body 33. For example, in the example shown in Figure 9 The intermediate shaft 38 is arranged close to the middle position of the turnover beam body 33. Therefore, the intermediate shaft 38 provides part of the support force for the turnover beam body 33, so that the turnover beam body 33 can rotate relative to the box door 2, and at the same time, the deformation of the box door 2 due to its own gravity can be prevented, and the intermediate shaft 38 can bear part of the external force, avoiding that the local stress concentration causes damage to the rotating shaft 31, and improving the service life of the whole turnover beam 3.

[0075] According to the refrigerator 100 of the embodiment of the utility model, as shown in Figures 1-10 The refrigerator 100 comprises a box body 1, a plurality of box doors 2 and at least one turnover beam 3.

[0076] Specifically, one side of the box body 1 in the first direction is open. The plurality of box doors 2 are rotatably arranged on the open side of the box body 1, and the plurality of box doors 2 are arranged along a second direction, and the second direction is perpendicular to the first direction. The turnover beam 3 is arranged between the two adjacent box doors 2, and the turnover beam 3 is pivotally connected with one of the two adjacent box doors 2.

[0077] For example, in Figures 1-2In the example, there are two doors 2 (one of which is not shown). The two doors 2 are symmetrically arranged on the open side of the body 1, and the side of the two doors 2 furthest from each other in a second direction is rotatably connected to the body 1. The refrigerator 100 achieves a sealed internal design through the cooperation of the body 1 and the doors 2, preventing heat exchange interference with the external environment from interfering with the internal temperature regulation of the refrigerator 100, thus facilitating the temperature regulation of objects inside the refrigerator 100. A flip beam 3 is provided between the two doors 2, which separates the gap between the two doors 2 from the outside, preventing hot air from entering the interior of the refrigerator 100 through the gap, thus providing heat insulation.

[0078] The flip beam 3 includes a limiting mechanism (not shown in the figure), one end of which is connected to one of the two adjacent door 2. The flip beam 3 can switch between a first state and a second state.

[0079] During the transition from the first state to the second state, the limiting mechanism moves upward, and the tilting beam 3 rotates until it is perpendicular to the door 2 (e.g., Figure 8 As shown); during the process of the flip beam 3 switching from the second state to the first state, the limiting mechanism moves downward, and the flip beam 3 rotates until it is parallel to the box door 2 (as shown). Figure 4 (As shown).

[0080] For example, in Figures 3-8 In the example, the flip beam 3 is disposed on the side wall of the door 2 facing the interior of the box 1, and the flip beam 3 is along a third direction (e.g., Figure 1 (Extending in the vertical direction). Specifically, the limiting mechanism can be located near the end of the door 2.

[0081] When a user needs to open the door 2 to take out or put in items, they can pull the door 2, which is equipped with a flip beam 3. Since one end of the limiting mechanism is connected to the door 2, the rotation of the door 2 can move the limiting mechanism upward, causing the flip beam 3 to switch to a state perpendicular to the door 2 (i.e., the second state), thus opening the door 2. At the same time, the flip beam 3 is prevented from obstructing the user's view, making the opened space more open. This allows the user to easily take out or put in items, and the flip beam 3 will not be accidentally touched and damaged during the process of taking out or putting in items.

[0082] When the door 2 is closed, push the door 2 with the flip beam 3. Since one end of the limiting mechanism is connected to the door 2, the door 2 can rotate to move the limiting mechanism downward, so that the flip beam 3 switches to a state parallel to the door 2 (i.e., the first state), thus closing the door 2. The flip beam 3 can separate the gap between the two doors 2 from the outside, preventing hot air from entering the interior of the refrigerator 100 through the gap, thus playing a heat insulation role.

[0083] In addition, the setting of the limiting mechanism can accurately control the motion track of the turnover beam 3, ensure that the turnover beam 3 can accurately switch to the second state, prevent the turnover beam 3 from rotating due to user error, and cause the case door 2 to be unable to open or close, and ensure the working reliability of the turnover beam 3. Moreover, the user does not need to manually rotate the turnover beam 3 to be parallel to the case door 2 and then close the case door 2, so that the operation of the user is more convenient, and the use experience of the user is improved.

[0084] According to the refrigerator 100, the turnover beam 3 on the case door 2 comprises a limiting mechanism, one end of the limiting mechanism is connected with one of the adjacent two case doors 2, the turnover beam 3 is prevented from rotating due to user error, the case door 2 is prevented from being unable to close, the working reliability of the turnover beam 3 is ensured, the operation of the user is more convenient, the use experience of the user is improved, and the setting of the turnover beam 3 ensures the heat preservation performance of the refrigerator 100.
