Description

Technical Field

[0001] The present application relates to the technical field of refrigeration, and particularly relates to a refrigerator and its flipping mechanism. Background Art

[0002] Some refrigerators, especially large-capacity refrigerators, usually adopt a double-door structure, and a flipping beam is usually provided on the door body of the double doors. The flipping beam rotates from a retracted position to an extended position during the process of the door body being opened to closed, and seals the gap between the two door bodies of the double doors to prevent cold air leakage.

[0003] In order to enable the flipping beam to be stably maintained in the retracted position during the opening process of the door body so as not to affect the opening and closing of the door body, a locking mechanism is usually further provided on the flipping beam. The locking mechanism locks the flipping beam in the retracted position by restricting the rotation of the rotating member that rotatably connects the flipping beam and the door body during the opening process of the door body, effectively preventing the collision risk caused by the incorrect position of the flipping beam.

[0004] However, in the related art, the locking mechanism for locking the flipping beam in the retracted position has poor reliability and is prone to failure. Summary of the Invention

[0055] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0056] For technologies, methods, and devices known to those of ordinary skill in the relevant art, detailed discussions may not be made, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0057] In the description of the present application, it should be understood that using words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without further statement, the above words have no special meaning, so they cannot be understood as limiting the protection scope of the present application.

[0058] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0059] Since it can meet people's higher low-temperature storage needs, with the improvement of living standards, large-capacity refrigerators are becoming more and more popular among people.

[0060] Large-capacity refrigerators are mostly designed with a side-by-side door structure. In a refrigerator with a side-by-side door structure, in order to enable the two relatively arranged door bodies of the side-by-side doors to be opened and closed independently, there is usually a gap between the two door bodies, which causes the two door bodies not to completely form a sealed space with the refrigerator cabinet, and the cold air in the cabinet will inevitably leak from the gap between the two door bodies.

[0061] In order to reduce the loss of cold air in the refrigerator, a refrigerator with a flip beam has emerged. The flip beam is rotatably connected to the inner surface of the door body of the side-by-side door through a rotating member and rotates between a retracted position and an extended position as the door body opens and closes. Among them, when the corresponding door body is opened, the flip beam rotates to the retracted position, so as not to affect the opening and closing of the door body; when the corresponding door body is closed, the flip beam rotates to the extended position, so as to close the gap between the two door bodies to prevent the cold air in the storage compartment inside the refrigerator from leaking from the gap between the two door bodies.

[0062] Although the flip beam can play a role in reducing the loss of cold air in the refrigerator, in actual use, it is found that when the door body with the flip beam is in the open state, due to reasons such as user misoperation, the flip beam often flips from the retracted position to the extended position by mistake, resulting in a collision between the flip beam and the cabinet or the other door body when the door body is closed. This kind of collision not only easily causes problems such as structural damage and affects the service life, but also easily affects the sealing effect of the flip beam, causing cold air leakage, resulting in energy waste and affecting the refrigeration effect.

[0063] In view of the problem that the above-mentioned flip beam flips incorrectly during the opening process, affecting the sealing reliability and service life, an effective solution is to provide a locking mechanism on the flip beam. The locking mechanism locks the flip beam in the retracted position by restricting the rotation of the rotating member that rotatably connects the flip beam and the door body during the opening process of the door body, effectively preventing the collision risk brought by the incorrect position of the flip beam, and thus achieving the purpose of improving the sealing reliability and extending the service life.

[0064] However, the locking mechanism used in the related art to lock the flip beam in the retracted position can only achieve single-channel locking, with poor reliability and easy to fail.

[0065] In view of the above situation, the present application provides a refrigerator and its flip mechanism, which reduces the collision risk brought by the incorrect position of the flip beam by improving the locking reliability of the flip beam, improves the sealing reliability and structural reliability of the refrigerator, so that the refrigerator has good cold storage performance and a long service life.

[0066] Figures 1-9 Exemplarily shows the structure of the refrigerator and its flip mechanism in the present application.

[0067] See Figures 1-9 , in the present application, the refrigerator 10 includes a box body 100, a pair of doors 200, and a flipping mechanism 300.

[0068] A storage compartment 101 is provided inside the box body 100.

[0069] The pair of doors 200 is arranged at the opening 102 of the storage compartment 101 to open or close the opening 102 of the storage compartment 101.

[0070] The flipping mechanism 300 includes a flipping beam 1, a rotating member 21, and a locking mechanism 3. The flipping beam 1 is rotatably connected to the door body 201 of the pair of doors 200 through the rotating member 21, so as to rotate from a retracted position to an extended position relative to the door body 201 during the process of the door body 201 closing from an open state, and seal the gap between the two door bodies 201 of the pair of doors 200. The rotating member 21 is provided with a first engaging portion 214 and a second engaging portion 215. The locking mechanism 3 is disposed on the flipping beam 1 so as to be movable up and down, and includes a locking member 31. The locking member 31 includes a base 311 and a first locking portion 312 and a second locking portion 313 disposed on the base 311, and moves from a locking position to an unlocking position in the up and down direction during the process of the door body 201 closing from an open state. Wherein, when the locking member 31 is in the locking position, the first locking portion 312 and the second locking portion 313 are respectively in contact with the first engaging portion 214 and the second engaging portion 215 to limit the rotation of the rotating member 21, so as to lock the flipping beam 1 in the retracted position; when the locking member 31 is in the unlocking position, the first locking portion 312 and the second locking portion 313 are respectively separated from the first engaging portion 214 and the second engaging portion 215 to release the limitation on the rotation of the rotating member 21, so as to release the locking of the flipping beam 1 in the retracted position.

[0071] In the above solution, since the locking mechanism 3 for locking the flipping beam 1 in the retracted position includes a first locking portion 312 and a second locking portion 313, the rotating member 21 for rotatably connecting the flipping beam 1 and the door body 201 is provided with a first engaging portion 214 and a second engaging portion 215, and the first locking portion 312 cooperates with the first engaging portion 214 to achieve one locking, and at the same time, the second locking portion 313 cooperates with the second engaging portion 215 to achieve another locking. Therefore, the locking mechanism 3 can cooperate with the rotating member 21 to achieve two-lockings. In this way, compared with the single-locking situation in the related art, the locking reliability can be effectively improved, because the two-lockings act simultaneously, the flipping beam 1 can be more reliably locked in the retracted position, and the flipping of the flipping beam 1 can be more reliably prevented. Moreover, when one of the two-lockings fails, the other locking can still play a locking role, so that the locking will not fail.

[0072] It can be seen that based on the cooperation between the first locking portion 312 and the first mating portion 214, and the cooperation between the second locking portion 313 and the second mating portion 215, the locking reliability of the turnover beam 1 can be effectively improved. This is beneficial to reducing the collision risk caused by the wrong position of the turnover beam, improving the sealing reliability and structural reliability of the refrigerator, so that the refrigerator has better cold storage performance and a longer service life.

[0073] Among them, referring to Figures 3-6 , in some embodiments, the first mating portion 214 is located below the second mating portion 215. At this time, the first mating portion 214 and the second mating portion 215 are not aligned in the up and down direction, but are arranged in a staggered manner. They can cooperate with the first locking portion 312 and the second locking portion 313 to achieve two locks at different up and down positions. In this way, not only the number of locking parts increases and the locking area increases, but also the two staggered locks up and down can better share the force and are less likely to be damaged simultaneously. Therefore, the locking reliability is higher. At the same time, the two locks are arranged up and down, occupying different up and down spaces, which is also convenient for the arrangement and cooperation of the first locking portion 312, the second locking portion 313, the first mating portion 214 and the second mating portion 215. Among them, when the first mating portion 214 is located below the second mating portion 215, part of the first mating portion 214 can be located below the second mating portion 215, so that the upper and lower parts of the two are staggered and partially overlapped in the up and down direction. Or, the first mating portion 214 can also be entirely located below the second mating portion 215, so that the two are completely staggered up and down and do not overlap in the up and down direction. Among them, compared with the former, the latter is less likely to be damaged simultaneously. Therefore, the locking reliability is higher.

[0074] In addition, continue to refer to Figures 3-6, in some embodiments, the rotating member 21 has an inner cavity 213. The first engaging portion 214 is disposed on the outer wall of the inner cavity 213. The second engaging portion 215 is disposed on the inner wall of the inner cavity 213. The second locking portion 313 is inserted into the inner cavity 213 and contacts the second engaging portion 215 to limit the rotation of the rotating member 21. At this time, the first engaging portion 214 and the second engaging portion 215 are not both located on one of the inner and outer walls of the rotating member 21, but one is located on the outer wall of the rotating member 21 and the other is located on the inner wall of the rotating member 21. They are arranged in a staggered manner in the inner and outer directions of the rotating member 21, and can cooperate with the first locking portion 312 and the second locking portion 313 to achieve two locks at different positions in the inner and outer directions of the rotating member 21. In this way, not only the number of locking positions increases and the locking area increases, but also the two locks arranged in a staggered manner inside and outside can better share the force and are less likely to be damaged simultaneously. Therefore, the locking reliability is higher. At the same time, the two locks are arranged inside and outside, occupying different inner and outer spaces, which is also more convenient for the arrangement and cooperation of the first locking portion 312, the second locking portion 313, the first engaging portion 214 and the second engaging portion 215. At the same time, the second engaging portion 215 is disposed on the inner wall of the rotating member 21, and the second locking portion 313 is inserted into the inner cavity 213 of the rotating member 21 and cooperates with the second engaging portion 215, which can also play a guiding role, enabling the locking member 31 to move up and down more reliably and achieving more effective locking.

[0075] In the foregoing embodiments, the first engaging portion 214 and the second engaging portion 215 may include recesses 218 or protrusions 219 on the rotating member 21. Among them, when one of the first engaging portion 214 and the second engaging portion 215 includes a recess 218 and the other includes a protrusion 219, it is more convenient to arrange the first engaging portion 214 and the second engaging portion 215 on the rotating member 21, and it is also more convenient for the first engaging portion 214 and the second engaging portion 215 to cooperate with the first locking portion 312 and the second locking portion 313 respectively. In particular, it is convenient for the first engaging portion 214 and the second engaging portion 215 to be arranged in a staggered manner in the up and down direction and the inner and outer directions of the rotating member 21, and for the correspondingly arranged first engaging portion 214 and second engaging portion 215 to cooperate with the first locking portion 312 and the second locking portion 313. As an example, see Figure 6 , in some embodiments, the first engaging portion 214 includes a recess 218. For example, see Figure 6 , in some embodiments, the first engaging portion 214 includes a notch 216 disposed on the outer wall of the rotating member 21. In this way, it is more convenient to cooperate with the first locking portion 312 located outside the rotating member 21 to achieve the locking function, while the second engaging portion 215 includes a protrusion 219. For example, see Figure 6 , in some embodiments, the second engaging portion 215 includes a protrusion 217 disposed on the inner wall of the rotating member 21. In this way, it is more convenient to cooperate with the second locking portion 313 inserted into the rotating member 21 to achieve the locking function.

[0076] As a way of the cooperation between the first locking part 312 and the first mating part 214 in the foregoing embodiments, refer to Figures 3-9 , the first locking part 312 has a first locking surface 315. The first locking part 312 abuts against the first mating part 214 through the first locking surface 315 to limit the rotation of the rotating part 21. At this time, the first locking part 312 realizes the locking function through the abutment between its first locking surface 315 and the first mating part 214. Among them, the first locking surface 315 can be a flat surface or a curved surface. When the first locking surface 315 is a flat surface, it is more convenient to realize the required rotation locking function.

[0077] In order to make the first locking surface 315 a flat surface, refer to Figure 9 , and in combination with Figure 3 and Figure 4 , in some embodiments, the first locking part 312 is rectangular, and the first locking surface 315 is the surface of the first locking part 312 parallel to the up-down direction. In this way, a flat first locking surface 315 can be obtained based on a relatively simple structure. And, as shown in Figure 3 and Figure 4 , only by arranging the first locking part 312 on one side of the rotating part 21 along the thickness direction of the flipping beam 1 and making the first locking surface 315 face the rotating part 21, it is convenient to realize the abutment between the first locking surface 315 and the first mating part 214 at the locking position, effectively preventing the rotation of the rotating part 21 and the flipping beam 1 and realizing the required rotation locking function. In particular, the first locking part 312 and the first locking surface 315 arranged in this way are convenient to abut against the first mating part 214 configured as the notch 216, realizing the required rotation locking function.

[0078] In the case where the first locking surface 315 is a flat surface, refer to Figures 3-4 as well as Figure 6 and Figure 8 , in some embodiments, along the horizontal direction, the edge of the first locking surface 315 is located outside the first mating part 214. At this time, the horizontal edge of the first locking surface 315 extends beyond the first mating part 214 and does not engage with the first mating part 214. That is to say, the first locking surface 315 includes a part that abuts against the first mating part 214 and a part that does not abut against the first mating part 214, and the area is relatively large. Under the same abutting force, the force per unit area of the first locking surface 315 is smaller and it is less likely to be damaged. Therefore, the structural reliability is higher and it is more conducive to realizing a reliable locking function.

[0079] In addition, as a way of the cooperation between the second locking part 313 and the second mating part 215 in the foregoing embodiments, refer to Figures 3-9, the second locking portion 313 has a second locking surface 316. The second locking portion 313 abuts against the second mating portion 215 through the second locking surface 316 to limit the rotation of the rotating member 21. At this time, the second locking portion 313 realizes the locking function through the abutment between its second locking surface 316 and the second mating portion 215. Among them, the second locking surface 316 can be a flat surface or a curved surface. When the second locking surface 316 is a flat surface, it is more convenient to realize the required rotation locking function.

[0080] To make the second locking surface 316 a flat surface, refer to Figure 9 , and in combination with Figure 3 and Figure 4 , in some embodiments, the second locking portion 313 is cylindrical, and the second locking surface 316 is a flat surface located on the side wall of the second locking portion 313, for example, a flat surface recessed or protruding inward from the side wall of the second locking portion 213. In this way, a flat second locking surface 316 can be obtained based on a relatively simple structure, and as Figure 3 and Figure 4 shown, it is convenient for the second locking portion 313 to be inserted into the rotating member 21 and cooperate with the second mating portion 215 configured as the protrusion 217 mentioned above to realize the required rotation locking function.

[0081] In addition, refer to Figure 9 , in some embodiments, the first locking portion 312 is angularly connected to the base 311, so that a card slot 317 is formed between the first locking portion 312 and the base 311, and the two side edges of the card slot 317 along the horizontal direction are open. At this time, the card slot 317 formed between the first locking portion 312 and the base 311 is non-closed in the horizontal direction. In this way, when cooperating with the first mating portion 214, the first mating portion 214 does not need to be inserted into the card slot 317, the assembly is simpler, and it is less likely to be broken or damaged, and the structural reliability is higher.

[0082] As mentioned above, the locking member 31 controls whether to lock the flip beam 1 in the retracted position by moving up and down between the unlocking position and the locking position.

[0083] Among them, to facilitate the movement of the locking member 31 between the locking position and the unlocking position, refer to Figures 1-8 , in some embodiments, a guiding portion 103 is provided on the box body 100. The locking mechanism 3 includes a transmission mechanism 32. The transmission mechanism 32 is connected to the locking member 31 and cooperates with the guiding portion 103 to drive the locking member 31 to move up and down together under the action of the guiding portion 103. In this way, during the process of opening and closing the door, the guiding portion 103 can act on the transmission mechanism 32 to make the transmission mechanism 32 move up and down, and then drive the locking member 31 to move up and down, realizing the movement of the locking member 31 between the locking position and the unlocking position.

[0084] In the case where the transmission mechanism 32 is provided, refer to Figure 4 , in some embodiments, the transmission mechanism 32 is connected to the middle part of the locking member 31 in the horizontal direction. In this way, compared with the case where the transmission mechanism 32 is connected to the two ends of the locking member 31 in the horizontal direction, the locking member 31 is more evenly stressed, and a more stable up-and-down movement process can be achieved.

[0085] To achieve the connection of the transmission mechanism 32 to the middle part of the locking member 31 in the horizontal direction, refer to Figure 4 and Figure 8 , in some embodiments, the transmission mechanism 32 includes a transmission rod 324. The transmission mechanism 32 is connected to the locking member 31 through the transmission rod 324. Moreover, the transmission rod 324 includes a first rod section 325 and a second rod section 326. The first rod section 325 is connected to the locking member 31 through the second rod section 326. Among them, the second rod section 326 is bent toward one side of the first rod section 325 relative to the first rod section 325, so that the second rod section 326 is connected to the middle part of the locking member 31 in the horizontal direction. In this way, based on a relatively simple structure, the connection of the transmission mechanism 32 to the middle part of the locking member 31 in the horizontal direction can be achieved, the stress uniformity of the locking member 31 can be improved, and the movement smoothness of the locking member 31 can be enhanced.

[0086] In addition, in the case where the transmission mechanism 32 is provided, in order to facilitate the cooperation between the transmission mechanism 32 and the guiding portion 103 to guide the up-and-down movement of the locking member 31, refer to Figures 1-8 , in some embodiments, one of the guiding portion 103 and the transmission mechanism 32 includes a guiding groove 104, and the other includes a moving block 321. The guiding groove 104 cooperates with the moving block 321 to drive the up-and-down movement of the locking member 31. In this way, during the opening and closing process of the door body 201, the moving block 321 enters and exits the guiding groove 104, and the locking member 31 can move up and down, switching between the locked position and the unlocked position, effectively meeting the unlocking requirement in the closed state and the locking requirement in the opened state.

[0087] Among them, to facilitate the entry and exit of the moving block 321 from the guiding groove 104, refer to Figures 1-8, in some embodiments, one end of the moving block 321 facing the guiding groove 104 in the up-and-down direction is provided with a first surface 322 and a second surface 323 connected to the end of the first surface 322, and the second surface 323 is an inclined surface. In this way, the second surface 323 which is an inclined surface can play a guiding role during the process of the moving block 321 entering and / or exiting the guiding groove 104, facilitating the smooth entry and / or exit of the moving block 321 from the guiding groove 104 and preventing the moving block 321 from colliding violently with the guiding groove 104. Among them, the number of the second surfaces 323 can be one or two. When the number of the second surfaces 323 is one, the second surface 323 is only provided at one end of the first surface 322, and the corresponding second surface 232 only guides during the process of the moving block 321 entering or leaving the guiding groove 104. When the number of the second surfaces 323 is two, the second surfaces 323 are provided at opposite ends of the first surface 322, and these two second surfaces 232 can respectively guide during the process of the moving block 321 entering and leaving the guiding groove 104, making the moving block 321 enter and exit the guiding groove 104 smoothly.

[0088] In addition, in order to facilitate the locking member 31 to return from the unlocking position to the locking position, refer to Figure 3 and Figure 4 , in the foregoing embodiments, the flipping mechanism 300 may further include a reset member 33, and the reset member 33 abuts between the locking mechanism 3 and the flipping beam 1 for moving the locking member 31 from the unlocking position to the locking position. In this way, during the door opening process, under the action of the reset member 33, the locking member 31 can automatically return from the unlocking position to the locking position, which is simple, convenient and efficient.

[0089] Among them, the reset member 33 may abut between the flipping beam 1 and the locking member 31 of the locking mechanism 3, or, in the case where the locking mechanism 3 includes a transmission mechanism 32 as described above, the reset member 33 may also abut between the flipping beam 1 and the transmission mechanism 32 of the locking mechanism 3. When the reset member 33 abuts between the locking member 31 and the flipping beam 1, the reset member 33 directly applies a reset force from the unlocking position to the locking position to the locking member 31 without being transmitted through the transmission mechanism 32. Therefore, it is more beneficial for the locking member 31 to return from the unlocking position to the locking position smoothly and efficiently.

[0090] In the case where the reset member 33 abuts between the locking member 31 and the flipping beam 1, refer to Figures 3-5 and Figure 9, the locking member 31 may further include a support portion 314. The support portion 314 is disposed on the base 311 and protrudes relative to the base 311, and the reset member 33 is sleeved on the support portion 314. The provided support portion 314 can support the reset member 33, facilitating the setting of the reset member 33 on the locking member 31. Moreover, the support portion 314 can also play a guiding role for the reset member 33 during the up-and-down movement of the locking member 31, facilitating the deformation of the reset member 33 in the up-and-down direction and driving the locking member 31 to accurately reset.

[0091] In the case where the support portion 314 is provided, referring to Figures 3-4 and Figure 9 , in some embodiments, the first locking portion 312 and the second locking portion 313 are located on the same side of the base 311, and the support portion 314 protrudes relative to the base 311 in a direction away from the first locking portion 312 and the second locking portion 313. In this way, the structure is compact and the layout is reasonable. It is not only convenient for the first locking portion 312 and the second locking portion 313 to contact the first engaging portion 214 and the second engaging portion 215 respectively for locking, but also convenient for the reset member 33 to apply a reset force to the locking member 31 to move the locking member 31 from the unlocked position to the locked position.

[0092] In addition, in the case where the support portion 314 is provided, the number of the support portions 314 can be one, two or more. When the locking member 31 includes two support portions 314, referring to Figures 3-4 and Figure 9 , these two support portions 314 can be arranged side by side in the horizontal direction, and a reset member 33 is sleeved on each support portion 314. In this way, different parts of the locking member 31 in the horizontal direction can be affected by the reset member 33, and it can move up and down more smoothly.

[0093] In addition, other measures can also be adopted to improve the moving smoothness of the locking member 31. For example, referring to Figures 3-5 and Figure 9 , in some embodiments, the flipping mechanism 300 includes a guiding groove 318 and a guiding rod 16. One of the guiding groove 318 and the guiding rod 16 is disposed on the flipping beam 1, and the other is disposed on the base 311. The guiding rod 16 is located in the guiding groove 318 to guide the up-and-down movement of the locking member 31. In this way, the guiding rod 16 and the guiding groove 318 can cooperate with each other to guide the up-and-down movement of the locking member 31, effectively improving the moving smoothness of the locking member 31, so that the locking member 31 can move more accurately between the locked position and the unlocked position, and reliably realize the required locking and unlocking functions.

[0094] Specifically, continue to refer to Figures 3-5 and Figure 9In some embodiments, the flip mechanism 300 includes two guide rods 16, which are arranged side by side in the horizontal direction and are both located in the guide groove 318. Since the two guide rods 16 can cooperate with the guide groove 318 to guide the locking member 31 to move up and down, it is more conducive to improving the movement stability of the locking member 31.

[0095] Next, combine Figures 1-9 The embodiments shown are used to further illustrate the present application.

[0096] For the convenience of description, the following Figure 1 The refrigerator 10 is placed upright for use, and the directions are defined based on the state of the refrigerator 10 when it is used upright, where the directions that are equal to and opposite to gravity are "down" and "up", respectively, and the directions facing and away from the user of the refrigerator 10 are "front" and "back", respectively. When the refrigerator 10 is placed upright for use, the height direction of the refrigerator 10 is along the up-down direction, the width direction is along the left-right direction, and the thickness direction is along the front-back direction.

[0097] like Figures 1-9 As shown, in this embodiment, the refrigerator 10 includes a cabinet 100 , a double-door 200 , and a turning mechanism 300 .

[0098] A storage room 101 for storing articles is provided in the box body 100. An opening 102 is provided at the front side of the storage room 101 for taking and placing articles.

[0099] The double-leaf door 200 is disposed at the opening 102 of the storage chamber 101 and includes two door bodies 201. Figure 1 As shown, the two door bodies 201 are arranged side by side along the horizontal direction (specifically the left and right direction), and the ends of the two door bodies 201 that are away from each other are rotatably connected to the box body 100, so that the two door bodies 201 can rotate in opposite directions to open or close the opening 102 of the storage room 101 to achieve a double-opening effect.

[0100] The flip mechanism 300 is used to seal the gap between the two door bodies 201 of the double-leaf door 200 when the double-leaf door 200 is closed, so as to prevent the cold energy in the storage chamber 101 from leaking. Figures 1-9 As shown, in this embodiment, the flip mechanism 300 is arranged on one of the two door bodies 201 of the double-leaf door 200, and includes a flip beam 1, a rotation connection mechanism 2 and a locking mechanism 3.

[0101] The flip beam 1 is disposed on the inner surface of the door body 201 and is rotatably connected to the door body 201 through a rotating connection mechanism 2, so that the flip beam 1 can rotate between the stowed position and the deployed position by rotating around a vertical axis. Figure 1 and Figure 2As shown, in this embodiment, the flipping beam 1 is a longitudinally elongated member extending in the vertical direction. One end of the flipping beam 1 away from the other door body 201 is connected to the door body 201 through a rotating connection mechanism 2, and the end close to the other door body 201 is free, so that the flipping beam 1 can rotate 90° around the vertical axis corresponding to the rotating connection mechanism 2, thereby realizing rotation between the retracted position and the swung-open position. Among them, when the door body 201 where it is located is in the open state, the flipping beam 1 is in the retracted position, substantially perpendicular to the inner surface of the corresponding door body 201; when the door body 201 where it is located is in the closed state, the flipping beam 1 rotates to the deployed position, substantially parallel to the inner surface of the corresponding door body 201. At this time, the flipping beam 1 can seal the gap between the two door bodies 201, prevent the cold air in the storage compartment 101 from leaking, maintain a good refrigeration environment in the storage compartment 101, and realize the effective refrigeration function of the refrigerator 10.

[0102] The rotating connection mechanism 2 is arranged on the flipping beam 1 and connects the flipping beam 1 and the door body 201 to realize the rotatable arrangement of the flipping beam 1 on the door body 201. As Figures 2-7 shown, in this embodiment, the flipping beam 1 is provided with a mounting portion 11, and the rotating connection mechanism 2 is arranged at the mounting portion 11 and includes a rotating member 21, a moving member 22 and an elastic member 23.

[0103] Among them, as Figure 5 shown, in this embodiment, the mounting portion 11 is generally cylindrical, and an installation hole 12 is provided inside it. The installation hole 12 is a circular hole for accommodating the rotating portion 212 of the rotating member 21 mentioned below. Part of the side wall of the mounting portion 11 is open, which is convenient for the rotating portion 212 of the rotating member 21 to enter the installation hole 12, and is also convenient for the connecting portion 211 of the rotating member 21 mentioned below to extend outside the installation hole 12 and be connected to the door body 201. One end of the mounting portion 11 facing the locking member 31 of the locking mechanism 3 (in Figures 3-5 it is the bottom end of the mounting portion 11) is open, which is convenient for the rotating portion 212 in the installation hole 12 to extend out and cooperate with the locking member 31 of the locking mechanism 3 to realize the locking function. One end of the mounting portion 11 facing away from the locking member 31 (in Figures 3-5 it is the top end of the mounting portion 11) is provided with an end wall, and a limiting hole 13 is provided on the corresponding end wall. A limiting groove 14 is recessed outward on the side wall of the limiting hole 13, and the corresponding limiting groove 14 is used to cooperate with the convex rib 223 of the moving member 22 mentioned below to limit the rotation of the moving member 22.

[0104] The rotating member 21 is used to rotatably connect the door body 201 and the flipping beam 1. As Figures 2-7 shown, in this embodiment, the rotating member 21 includes a rotating portion 212 and a connecting portion 211. The rotating portion 212 and the connecting portion 211 are connected to each other, and the connecting portion 211 is connected to the door body 201, and the rotating portion 212 is rotatably connected to the flipping beam 1. Specifically, asFigures 2-7 As shown, in this embodiment, the rotating part 212 is generally cylindrical, its axis extends vertically, and it is rotatably installed in the installation hole 12 in the installation part 11, concentric with the installation hole 12, and its side wall is connected to the connecting part 211. The connecting part 211 is generally block-shaped, it extends from the open part on the side wall of the installation part 11 to the outside of the installation hole 12, and is fixedly connected to the inner surface of the door body 201. In this way, the rotating part 212 is rotatably arranged on the turning beam 1 and is fixedly connected to the door body 201 through the connecting part 211, so that the turning beam 1 can be rotatably arranged on the door body 201, facilitating the turning beam 1 to rotate relative to the door body 201 between the retracted position and the deployed position during the opening and closing of the door body 201.

[0105] The moving part 22 is arranged in the installation part 11 and is located at the end of the rotating part 212 away from the locking part 31, and is used to control the rotation of the rotating part 212 relative to the turning beam 1. As Figures 3-7 shown, in this embodiment, the moving part 22 is generally cylindrical as a whole and includes a base 221 and a convex column 222. An uneven surface 224 is provided at one end of the base 221 facing the rotating part 212. Correspondingly, an uneven surface 224 is also provided at one end of the rotating part 212 facing the base 221. The two uneven surfaces 224 are engaged with each other, so that when the rotating part 212 rotates, it can abut against the base 221 and drive the moving part 22 to move up and down. The convex column 222 is connected to the end of the base 221 away from the rotating part 212, and a convex rib 223 is provided on the outer wall of the convex column 222. The corresponding convex rib 223 is embedded in the limiting groove 14 on the installation part 11 mentioned above. Specifically, in this embodiment, at least two convex ribs 223 are provided on the outer wall of the convex column 222 and are distributed at intervals in the circumferential direction, and the convex ribs 223 are rectangular. Correspondingly, at least two limiting grooves 14 are provided on the installation part 11, and the limiting grooves 14 are rectangular. In this way, the cooperation of the convex ribs 223 and the limiting grooves 14 can limit the rotation of the moving part 22, so that during the rotation of the rotating part 212, the moving part 22 does not rotate but only moves up and down. In this way, the rotating part 212 and the moving part 22 can move up and down synchronously and can rotate relative to each other.

[0106] The elastic part 23 is sleeved on the moving part 22 and abuts between the installation part 11 and the moving part 22, and is used to apply an elastic force to the moving part 22 to make the moving part 22 move towards the locking part 31, so as to facilitate the moving part 22 to drive the rotating part 212 to move towards the locking part 31 to reach the position where the locking function is realized. Combining Figures 3-4 and Figure 6It can be seen that in this embodiment, the elastic member 23 is a spring 231, which is sleeved outside the convex column 222 provided with a convex rib 223 of the moving member 22, and both ends are respectively abutted between the end wall of the mounting portion 11 away from the locking member 31 and the base 221 and compressed. In this way, the elastic member 23 can apply an elastic force to the moving member 22 to move the moving member 22 toward the locking member 31.

[0107] Based on the provided rotating member 21, moving member 22, and elastic member 23, the rotation connection mechanism 2 can achieve the rotational connection between the turning beam 1 and the door body 201, facilitating the rotation of the turning beam 1 between the retracted position and the deployed position.

[0108] The locking mechanism 3 is provided on the turning beam 1 and is used to control whether the turning beam 1 is locked in the retracted position during the opening and closing process of the door body 201 to meet the sealing requirements in the closed state of the door body 201 and the anti-collision requirements in the open state of the door body 201. As Figures 1-9 shown, in this embodiment, the locking mechanism 3 is movably arranged up and down on the turning beam 1 and includes a locking member 31, a transmission mechanism 32, and two reset members 33.

[0109] Among them, the locking member 31 can move between a locking position and an unlocking position in the up and down direction, and cooperate with the rotating portion 212 of the rotating member 21 at the locking position to lock the turning beam 1 in the retracted position by restricting the rotation of the rotating portion 212, realizing the locking function. As Figure 9 shown, in this embodiment, the locking member 31 is located on one side of the mounting portion 11 in the up and down direction (in Figure 3 and Figure 4 it is located on the lower side of the mounting portion 11), and includes a base 311, a first locking portion 312, a second locking portion 313, and two supporting portions 314.

[0110] The base 311 is generally cube-shaped, with a hollow interior and one end away from the rotating portion 212 open. A guiding groove 318 is provided on the outer wall of the base 311. The guiding groove 318 is rectangular and is used to cooperate with the guiding rod 16 on the turning beam 1 to guide the up and down movement of the locking member 31.

[0111] The first locking portion 312 is rectangular, vertically connected to the surface of the base 311 facing the rotating portion 212, and protrudes from the base 311 toward the direction close to the rotating portion 212, so that an L-shaped card slot 317 is formed between the first locking portion 312 and the base 311. The plane of the vertical side wall of the L-shaped card slot 317 formed by the first locking portion 312 serves as the first locking surface 315. The corresponding first locking surface 315 is used to cooperate with the first engaging portion 214 of the rotating portion 212 to prevent the rotation of the rotating portion 212 and form a locking.

[0112] The second locking portion 313 is generally cylindrical, vertically connected to the surface of the base 311 facing the rotating portion 212, and protrudes from the base 311 towards the rotating portion 212. The second locking portion 313 is located in the card slot 317, such that the second locking portion 313 is on one side in the thickness direction of the first locking portion 312 (which is also the thickness direction of the flipping beam 1). By means of removing materials such as cutting on the side wall of the second locking portion 313, an L-shaped groove is machined, and the vertical plane of the L-shaped groove serves as the second locking surface 316. The corresponding second locking surface 316 is used to cooperate with the second mating portion 215 of the rotating portion 212 to prevent the rotation of the rotating portion 212, forming another locking.

[0113] Two support portions 314 are provided on the side of the base 311 away from the rotating portion 212. Both extend into the base 311 and are arranged at intervals along the length direction of the base 311 (in Figure 3 and Figure 4 it is the horizontal direction, specifically Figure 3 and Figure 4 the left and right direction). Both support portions 314 are cylindrical and are vertically arranged, protruding from the inside of the base 311 towards the side away from the rotating portion 212 to the outside of the base 311, so as to facilitate the two support portions 314 to support the two reset members 33 and guide the two reset members 33 to deform in the up and down direction.

[0114] Specifically, as Figures 3-5 and Figure 9 shown, in this embodiment, a bracket 17 is provided on the flipping beam 1. The bracket 17 is located on one side of the mounting portion 11 in the up and down direction (in Figures 3-5Specifically, it is on the lower side), and is generally L-shaped, having a horizontal portion 171 extending in the horizontal direction and a vertical portion 172 extending in the vertical direction. Two guide rods 16 are provided on the horizontal portion 171 of the bracket 17. These two guide rods 16 are arranged at intervals along the length direction of the horizontal portion 171, and both extend into the guide groove 318 of the locking member 31, forming a sliding fit relationship with the guide groove 318, facilitating the up-and-down movement of the locking member 31. The locking member 31 is located between the horizontal portion 171 and the vertical portion 172 of the bracket 17, and the two supporting portions 314 of the locking member 31 are located on both sides of the two guide rods 16 in the horizontal direction, and can move up and down through the horizontal portion 171 of the bracket 17. A reset member 33 is sleeved on each supporting portion 314. In this embodiment, the reset member 33 is a spring 231, which abuts between the base 311 of the locking member 31 and the horizontal portion 171 of the bracket 17, applying an elastic force towards the rotating portion 212 to the locking member 31. Thus, the locking member 31 is movably disposed on the flipping beam 1 in the up-and-down direction, and under the action of the guide groove 318 and the two guide rods 16, it can move smoothly between a relatively upper locking position and a relatively lower unlocking position, and under the action of the two reset members 33, it can quickly return from the unlocking position to the locking position, locking the flipping beam 1 in the retracted position.

[0115] It can be seen that the locking member 31 of this embodiment can achieve double locking based on the cooperation between its first locking portion 312 and second locking portion 313 and the first mating portion 214 and second mating portion 215 of the rotating portion 212, effectively improving the locking reliability.

[0116] Combined with Figure 3 、 Figure 4 and Figure 6 it can be known that in this embodiment, both the first mating portion 214 and the second mating portion 215 are provided at one end of the rotating portion 212 facing the locking member 31. Specifically, in this embodiment, one end of the rotating portion 212 facing the locking member 31 is open, and there is an inner cavity 213 inside. The first mating portion 214 and the second mating portion 215 are respectively provided on the outer wall and the inner wall of the rotating portion 212.

[0117] Among them, as Figure 6 shown, in this embodiment, the first mating portion 214 is a notch 216 provided on the outer wall of the rotating portion 212. The notch 216 extends to one end of the rotating portion 212 facing the base 311 (in Figure 3 and Figure 4(i.e., the lower end of the rotating part 212), so that the notch 216 has a first wall 21a and two second walls 21b. The first wall 21a is away from the base 311 of the locking part 31 in the vertical direction. The two second walls 21b are spaced apart from each other, connected to both ends of the first wall 21a in the horizontal direction, and both extend from the first wall 21a to one end of the rotating part 212 facing the locking part 31. The first wall 21a and the two second walls 21b are both flat surfaces. In this way, the first wall 21a can fully contact the flat surface (in Figure 3 and Figure 4 , which is the top plane of the first locking part 312) of one end of the first locking part 312 facing the rotating part 212 in the vertical direction to achieve abutment. Moreover, the two second walls 21b can fully contact the first locking surface 315 of the first locking part 312 to achieve abutment. In this way, the notch 216 can effectively cooperate with the first locking part 312 to limit the rotation of the rotating part 212 and lock the flipping beam 1 in the stowed position.

[0118] As Figure 6 shown, in this embodiment, the second engaging part 215 is a protrusion 217 provided on the inner wall of the rotating part 212. The protrusion 217 is entirely located above the notch 216 and is rectangular. In this way, the protrusion 217 can fully abut against the second locking surface 316 on the second locking part 313 extending into the rotating part 212 to limit the rotation of the rotating part 212 and lock the flipping beam 1 in the stowed position.

[0119] It can be Figure 4 seen that when the locking part 31 is in the locked position, the first locking part 312 is located on one side of the rotating part 212 in the thickness direction of the flipping beam 1 (which is also the thickness direction of the first locking part 312). The first locking surface 315 faces the two second walls 21b of the notch 216 and abuts against the two second walls 21b. In this way, the rotation of the rotating part 212 can be restricted, so that the rotating part 212 can no longer rotate towards the first locking part 312 side, and further the flipping beam 1 can be locked in the stowed position. And, the second locking part 313 is inserted into the rotating part 212, and the protrusion 217 is stuck in the L-shaped groove on the second locking part 313 and abuts against the second locking surface 316 on the second locking part 313. In this way, the rotation of the rotating part 212 can be restricted, so that the rotating part 212 can no longer rotate towards the first locking part 312 side, and further the flipping beam 1 can be locked in the stowed position. Among them, the length of the first locking surface 315 is greater than the dimension of the notch 216 in the corresponding direction, so that the first locking part 312 has a larger force-bearing area in the locked state, higher structural reliability, and is less likely to be damaged.

[0120] It can be seen that in this embodiment, the first mating portion 214 and the second mating portion 215 can cooperate with the first locking portion 312 and the second locking portion 313 to achieve double locking at two positions above and below, which can more effectively improve the locking reliability.

[0121] The transmission mechanism 32 is disposed on the turning beam 1 so as to be movable up and down, and is used to cooperate with the guiding portion 103 on the box body 100 to drive the turning beam 1 to rotate between the retracted position and the deployed position as the door body 201 is opened and closed, and to drive the locking member 31 to move up and down between the locking position and the unlocking position as the door body 201 is opened and closed.

[0122] Specifically, as Figure 1 shown, in this embodiment, the guiding portion 103 is disposed on the inner surface of the top wall of the storage chamber 101 and includes a guiding groove 104. The front end and the lower end of the guiding groove 104 are open to facilitate the entry and exit of the transmission mechanism 32. The guiding groove 104 has an arc section to facilitate the cooperation between the guiding groove 104 and the transmission mechanism 32 to guide the turning beam 1 to rotate between the retracted position and the deployed position.

[0123] As Figures 3-5 and Figure 8 shown, in this embodiment, the transmission mechanism 32 includes a moving block 321 and a transmission rod 324. The moving block 321 penetrates out from the top of the turning beam 1 and is connected to the middle of the first locking portion 312 of the locking member 31 in the length direction through the transmission rod 324.

[0124] Wherein, a through hole 15 is provided at the top of the turning beam 1. The moving block 321 can move up and down through the through hole 15. During the closing process of the door body 201, the moving block 321 enters the guiding groove 104 and abuts against the top wall of the guiding groove 104, receives a downward pressure, moves downward, and then drives the locking member 31 to move downward to the unlocking position through the transmission rod 324, so that both the first locking portion 312 and the notch 216 and the second locking portion 313 and the protrusion 217 are separated, and the rotation of the rotating portion 212 and the turning beam 1 is no longer restricted, achieving the unlocking purpose. As Figure 8 can be known, in this embodiment, the moving block 321 is generally cube-shaped, and its top surface is configured to have a first surface 322 and two second surfaces 323. The two second surfaces 323 are connected to the two sides of the first surface 322 in the horizontal direction and are both configured as inclined surfaces. In this way, the two second surfaces 323 can perform avoidance and guiding during the process of the moving block 321 entering and exiting the guiding groove 104, facilitating the moving block 321 to enter and exit the guiding groove 104 more smoothly.

[0125] The transmission rod 324 is vertically arranged and is connected between the moving block 321 and the first locking portion 312 of the locking member 31, and includes a first rod segment 325 and a second rod segment 326. The first rod segment 325 is located horizontally on one side of the rotating member 21, and its upper and lower ends are respectively connected to the moving block 321 and the second rod segment 326. The second rod segment 326 is bent from the first rod segment 325 horizontally towards the side where the rotating member 21 is located and is connected to the middle of the first locking portion 312 in the length direction. In this way, when the moving block 321 moves up and down, the locking member 31 can be driven to move up and down through the transmission rod 324, and the locking member 31 is uniformly stressed and moves up and down smoothly.

[0126] Based on the structure of this embodiment, during the closing process of the door body 201, the top surface of the moving block 321 touches the guiding groove 104 on the box body 100, is pressed and moves downward, and pushes the locking member 31 downward through the transmission rod 324, causing the locking member 31 to move downward by a certain distance to reach Figure 4 the unlocking position shown. At this time, the first locking portion 312 of the locking member 31 is separated from the notch 216 on the outer wall of the rotating portion 212, and the protrusion 217 on the inner wall of the rotating portion 212 no longer engages with the L-shaped groove on the second locking portion 313 of the locking member 31. Therefore, both locks fail, the turning beam 1 is unlocked and can rotate, and then continue to close the door. The turning beam 1 can rotate to the unfolded position during the sliding process of the moving block 321 along the arc segment of the guiding groove 104 to seal the gap between the two door bodies 201.

[0127] During the opening process of the door body 201, as the moving block 321 slides outward along the arc segment of the guiding groove 104, the turning beam 1 can rotate to a certain angle so that the moving block 321 no longer touches the guiding groove 104. At this time, the locking member 31 is subjected to the resilience of the reset member 33 and moves upward, and pushes the moving block 321 upward through the transmission rod 324 until the locking member 31 moves upward to Figure 3 the locking position shown. At this time, the turning beam 1 rotates to the retracted position, the first locking portion 312 of the locking member 31 engages with the notch 216 on the outer wall of the rotating portion 212, and the protrusion 217 on the inner wall of the rotating portion 212 engages with the L-shaped groove on the second locking portion 313 of the locking member 31. Therefore, two upper and lower locks are formed, which can reliably prevent the turning beam 1 from rotating. At this time, the turning beam 1 is locked and fixed at the retracted position. In this way, in the open state of the door body 201, unless the moving block 321 is manually pressed downward for unlocking, otherwise, the turning beam 1 cannot rotate from the retracted position to the unfolded position. Therefore, it can effectively prevent the turning beam 1 from accidentally rotating to the unfolded position during the next closing process and colliding with the box body 100 or another door body 201.

[0128] It can be seen that in this embodiment, the structure of the flipping mechanism 300 is simple, and it can achieve double locking of the flipping beam 1, effectively reducing the collision risk caused by the incorrect position of the flipping beam 1, improving the sealing reliability and structural reliability of the refrigerator 10, so that the refrigerator 10 has good cold storage performance and a long service life.

[0129] The above are only exemplary embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
