[0038] As Figures 1 to 3 shown, in one embodiment, the refrigerator includes a cabinet 100, a door assembly 200, and a door 300. The cabinet 100 forms a storage compartment. The door assembly 200 is pivotally connected to the cabinet 100, and the door 300 is also pivotally connected to the cabinet 100. Specifically, the door assembly 200 and the door 300 are arranged in an opposing opening manner to open and close the storage compartment. In other words, the door assembly 200 and the door 300 are distributed along the left - right direction of the cabinet 100 and are pivotally connected to the left side and the right side of the cabinet 100 respectively.

[0039] Referring to Figures 1 to 3As shown, the door assembly 200 includes a door body 210, a vertical beam 220 and a transmission structure 230. The door body 210 is pivotally connected to the box body 100 via a pivot structure 240. The vertical beam 220 is disposed on the door body 210 and is pivotally connected to the door body 210. The transmission structure 230 is disposed on the door body 210, and the transmission structure 230 is disposed between the pivot structure 240 and the pivot axis of the vertical beam 220, so as to drive the vertical beam 220 to rotate toward the inner side of the door body 210 via the transmission structure 230 during the opening process of the door body 210.

[0040] Continue to refer to Figures 1 to 3 As shown, the vertical beam 220 is arranged on a side of the door body 210 relative to the pivoting side, specifically, the left side of the door body 210 is connected to the box body 100, and the opposite side, that is, the right side of the door body 210, that is, the vertical beam 220 is arranged on the right side of the door body 210, or in other words, the vertical beam 220 is arranged on the side of the door body 210 close to the box door 300, and the vertical beam 220 is located on the inner side of the door body 210, that is, the side of the door body 210 facing the box body 100, or in other words, it is arranged between the door body 210 and the box body 100. When the door body assembly 200 and the box door 300 are both in a closed state, a part of the vertical beam 220 is located between the door body 210 and the box body 100, and a part is located between the box door 300 and the box body 100, and the box door 300 presses the vertical beam 220, so that the vertical beam 220 seals the gap between the door body 210 and the box door 300.

[0041] When the door assembly 200 is opened, the position of the door 210 relative to the pivot structure 240 changes. Since the transmission structure 230 is disposed on the door 210, the position of the transmission structure 230 relative to the pivot structure 240 changes, thereby causing the transmission structure 230 to move, and then causing the transmission structure 230 to drive the vertical beam 220 to rotate toward the inner side of the door 210 (refer to Figure 3 The vertical beam 220 is rotated in a direction from the outside of the door body 210 (the side away from the box body 100) to the inside of the door body 210, thereby rotating the vertical beam 220 away from the box door 300.

[0042] In the solution of this embodiment, the door body 210 and the box body 100 are connected by a pivoting structure 240, and a transmission structure 230 is arranged between the pivoting structure 240 and the pivot axis of the vertical beam 220. When the door body assembly 200 is opened alone, the door body assembly 200 rotates, that is, its position relative to the pivoting structure 240 changes, and then drives the transmission structure 230 arranged on the door body 210 to change its position relative to the pivoting structure 240, thereby driving the rotation of the pivot axis of the vertical beam 220, that is, driving the vertical beam 220 to rotate, so that the vertical beam 220 moves to a position away from the door body 300. In other words, during the process of opening the door body assembly 200 alone, an external force is transmitted to the vertical beam 220 through the transmission structure 230, causing the vertical beam 220 to move to a position away from the door body 300, thereby reducing the interference between the vertical beam 220 and the box door 300 without a vertical beam, that is, reducing the resistance received by the vertical beam 220, making the opening of the door body assembly 200 smoother and helping to improve the user experience.

[0043] It should be noted that the refrigerator of the present application can be provided with one storage compartment or multiple storage compartments. In the case of multiple storage compartments, some of the storage compartments can adopt the way of the door body assembly and the box door opening in opposite directions, or all the storage compartments can adopt the way of the door body assembly and the box door opening in opposite directions. The refrigerator in the attached drawings is only an example, and those skilled in the art can adjust the number and distribution mode of the storage compartments according to needs.

[0044] As Figures 1 to 3 shown, the transmission structure 230 includes a transmission rod 231 and a gear set 232. The gear set 232 is arranged on the door body 210 and is in transmission connection with the pivot axis of the vertical beam 220. The transmission rod 231 is arranged between the pivoting structure 240 and the gear set 232 and extends from the pivoting structure 240 to the gear set 232. The transmission rod 231 is used to move with the opening of the door body 210, and then causes the gear set 232 to rotate, so as to drive the vertical beam 220 to rotate.

[0045] Referring to Figures 1 to 3 shown, specifically, the gear set 232 is arranged on the side of the door body 210 where the vertical beam 220 is provided. The transmission rod 231 extends along the left-right direction of the refrigerator, one end directly contacts the pivoting structure 240, and the other end directly or indirectly contacts the gear set 232. When the door body 210 is opened, the door body 210 rotates, and one end of the transmission rod 231 close to the pivoting structure 240 moves relative to the door body 210, and then the end close to the gear set 232 moves relative to the door body 210, so that the gear set 232 can move. After the gear set 232 moves, it drives the rotation of the pivot axis of the vertical beam 220, that is, drives the vertical beam 220 to rotate.

[0046] By arranging a transmission rod 231 and a gear set 232 in the transmission structure 230, and setting the transmission rod 231 between the pivot structure 240 and the gear set 232, the transmission rod 231 can move as the door body 210 rotates, and then the gear set 232 rotates, so as to drive the vertical beam 220 to rotate. The transmission from the pivot side of the door body assembly 200 to the vertical beam 220 is completed by using the transmission rod 231, and the structure is simpler.

[0047] It should be noted that in some other embodiments, the transmission structure can also use a plurality of gears arranged in sequence from the pivot structure to the pivot shaft of the vertical beam to realize the transmission from the pivot side of the door body assembly to the vertical beam.

[0048] As Figures 1 to 5 shown, the pivot structure 240 includes a hinge plate 241, a hinge shaft 242, and a support member 243. The door body 210 rotates relative to the box body 100 via the hinge shaft 242, and the support member 243 is fixedly arranged relative to the axis of the hinge shaft 242. The hinge plate 241 is used for fixedly connecting with the box body 100. The door body 210 is pivotally connected to the hinge plate 241 via the hinge shaft 242, and then pivotally connected to the box body 100. The support member 243 is fixed to the hinge plate 241.

[0049] Furthermore, the support member 243 has a support portion 2431 protruding from the front side towards the door body 210. The transmission rod 231 is pivotally connected to the door body 210, and the transmission rod 231 is provided with a support rib 2311 protruding from the rear side towards the door body 210. When the door body assembly 200 is in the closed state, the support rib 2311 abuts against the support portion 2431, and the support rib 2311 is displaced from the support portion 2431 as the door body 210 opens, so that the transmission rod 231 can rotate relative to the door body 210, that is, one end of the transmission rod 231 close to the gear set 232 can move relative to the gear set 232.

[0050] Referring to Figures 1 to 5 shown, specifically, the hinge plate 241 is a square sheet, a part of which is fixedly connected to the box body 100, and a part of which extends forward from the front side of the box body 100. The door body 210 is pivotally connected to the part of the hinge plate 241 extending from the front side of the box body 100 via the hinge shaft 242. In one implementation manner, the hinge shaft 242 can be fixed to the hinge plate 241, and the door body 210 rotates relative to the hinge shaft 242, so as to realize the rotation of the door body 210 relative to the box body 100. In another implementation manner, the hinge shaft 242 can also be fixed to the door body 210, and the hinge shaft 242 rotates relative to the hinge plate 241, so as to realize the rotation of the door body 210 relative to the box body 100.

[0051] Continuing to refer to Figures 1 to 5As shown, the support member 243 is fixed to the hinge plate 241, and can be integrally formed with the hinge plate 241, or separately formed and fixed on the hinge plate 241. The support member 243 has a support portion 2431 protruding from the front side towards the door body 210. That is to say, the distance between the support member 243 and the front side of the door body 210 is the smallest at the support portion 2431, and the distances between the portions of the support member 243 on the left and right sides of the support portion 2431 and the front side of the door body 210 are getting farther and farther.

[0052] Further, the transmission rod 231 is pivotally connected to the door body 210, and a protruding support rib 2311 is formed on one side of the transmission rod 231 facing the rear side of the door body 210. When the door body assembly 200 is in the closed state, the transmission rod 231 abuts against the support portion 2431 through the support rib 2311. When the door body 210 is opened, the relative positions of the door body 210 and the transmission rod 231 provided on the door body 210 with respect to the axis of the hinge shaft 242 change. Since the position of the support member 243 is fixed with respect to the axis of the hinge shaft 242, the relative position between the transmission rod 231 and the support member 243 changes, and then the support rib 2311 and the support portion 2431 are misaligned, that is, the support rib 2311 is no longer supported by the support portion 2431. The transmission rod 231 that loses support can rotate relative to the door body 210, referring to Figure 5 the direction indicated by the arc arrow in the figure. When the transmission rod 231 rotates relative to the door body 210, the end of the transmission rod 231 close to the gear set 232 moves relative to the gear set 232, so that the gear set 232 moves, and then drives the vertical beam 220 to rotate.

[0053] By providing the support member 243 fixed relative to the hinge shaft 242, the transmission rod 231 is pivotally connected to the door body 210. The support portion 2431 is formed on the support member 243, and the support rib 2311 is formed on the transmission rod 231. When the door body assembly 200 is in the closed state, the transmission rod 231 abuts against the support portion 2431 through the support rib 2311. When the door body 210 is opened, the relative positions of the door body 210 and the transmission rod 231 provided on the door body 210 with respect to the axis of the hinge shaft 242 change. Since the position of the support member 243 is fixed with respect to the axis of the hinge shaft 242, the relative position between the transmission rod 231 and the support member 243 changes, and then the support rib 2311 and the support portion 2431 are misaligned. The transmission rod 231 that loses support can rotate relative to the door body 210, that is, the end of the transmission rod 231 close to the gear set 232 can move relative to the gear set 232, so that the gear set 232 moves, and then drives the vertical beam 220 to rotate. By using the support rib 2311 and the support portion 2431 to realize the movement of the transmission rod 231 as the door body 210 is opened, the structure is simple.

[0054] By providing the hinge plate 241, the support member 243 is fixed to the hinge plate 241. Since the hinge plate 241 is more compact, the design is made simpler compared to directly designing on the cabinet 100.

[0055] As Figures 1 to 6 shown, the transmission structure 230 includes a rack 233 which is slidably arranged along the front - rear direction of the door body 210. The transmission rod 231 is in transmission connection with the gear set 232 via the rack 233, so as to drive the gear set 232 to move through the sliding rack 233.

[0056] Furthermore, the transmission structure 230 includes an elastic member 234 which is arranged between the rack 233 and the door body 210. When the door body 210 is in the closed state, the transmission rod 231 presses the rack 233 along the front - rear direction of the door body 210, and makes the elastic member 234 accumulate an elastic force for moving the rack 233 forward relative to the door body 210.

[0057] Referring to Figures 1 to 6 shown, specifically, the engaging teeth on the rack 233 are distributed along the front - rear direction of the door body 210. The rack 233 is meshed with the gear set 232 through the engaging teeth. During the process of the rack 233 sliding along the front - rear direction of the door body 210, it drives the gear set 232 to move through the meshing relationship with the gear set 232, thereby causing the vertical beam 220 to rotate.

[0058] One end of the rack 233 close to the front side surface of the door body 210 is provided with an extension part extending towards the pivoting side of the door body 210. A support platform is formed on the door body 210, and the support platform is located between the extension part of the rack 233 and the rear side surface of the door body 210. The elastic member 234 is a spring, and the elastic member 234 is arranged between the extension part of the rack 233 and the support platform.

[0059] Referring to Figures 1 to 6 shown, when the door body assembly 200 is in the closed state, the transmission rod 231 presses the rack 233 along the direction from the front to the rear of the door body 210, and then makes the rack 233 press the elastic member 234, so that the elastic member 234 is in a compressed state, and the elastic member 234 accumulates an elastic force for moving the rack 233 forward relative to the door body 210.

[0060] When the door body 210 is opened, the support rib 2311 is displaced from the support part 2431, causing the transmission rod 231 to lose support, that is, it can no longer press the rack 233. In this way, the elastic member 234 releases the accumulated elastic force, making the rack 233 slide towards the front side surface of the door body 210, thereby driving the gear set 232 to move, and further driving the vertical beam 220 to rotate.

[0061] By providing the rack 233, the transmission rod 231 is drivingly connected to the gear set 232 via the rack 233, enabling better realization of the conversion between non-rotational movement and rotational movement, and helping to make the movement of the gear set 232 smoother.

[0062] It should be noted that the door assembly is configured to have a force that drives the transmission rod to rotate in the closed state, and the driving rotation direction is such that the end of the transmission rod close to the hinge axis approaches the rear side surface of the door. The elastic force accumulated by the elastic member between the rack and the door is one implementation. In some other embodiments, instead of providing an elastic member between the rack and the door, the support member and the support rib are made of materials that can magnetically attract each other, so that there is a magnetic attraction force between the support member and the support rib; or, the transmission rod and the door are connected via a pre-tensioned spring. However, in the case where no elastic member is provided between the rack and the door, the transmission rod is directly or indirectly connected to the rack.

[0063] In addition, in some other embodiments, the rack may not be provided, and the transmission rod is directly or indirectly connected to the gear set.

[0064] As Figures 1 to 6 shown, further, the gear set 232 includes a first gear 2321, a second gear 2322, and a third gear 2323. The first gear 2321 is meshingly connected to the rack 233. The second gear 2322 is meshingly connected to the first gear 2321. The third gear 2323 is concentrically and fixedly connected to the pivot shaft of the vertical beam 220 and is meshingly connected to the second gear 2322.

[0065] Specifically, the third gear 2323 can be integrally formed on the outer periphery of the pivot shaft of the vertical beam 220, or can be separately formed and sleeved on the outer periphery of the pivot shaft of the vertical beam 220. As Figure 6 shown in the middle plane, when the rack 233 slides toward the front side surface of the door 210, driving the first gear 2321 to rotate counterclockwise, the first gear 2321 drives the second gear 2322 to rotate clockwise, and the second gear 2322 drives the third gear 2323 to rotate counterclockwise, that is, driving the vertical beam 220 to rotate counterclockwise, that is, causing the vertical beam 220 to rotate inward toward the door 210. The structural form of the three gears forming the gear set 232 is more reasonable.

[0066] It should be noted that in some other embodiments, the number of gears in the gear set can also be one, five, or more.

[0067] As Figure 3 shown, the distance between the rotation axis of the transmission rod 231 and the end close to the vertical beam 220 is greater than the distance between the rotation axis of the transmission rod 231 and the end close to the pivot side of the door 210. Referring to Figure 3As shown, specifically, the distance from the rotation axis of the transmission rod 231 to its right end is greater than the distance from the rotation axis to its left end. Through the above structural arrangement, it helps to make the end of the transmission rod 231 close to the vertical beam 220 have a greater degree of movement during the opening process of the door body 210, thereby driving the vertical beam 220 to have a greater degree of movement and further reducing the interference between the vertical beam 220 and the box door 300.

[0068] As Figure 1 and Figure 6 As shown, further, a flexible pad 221 is provided on the surface of the vertical beam 220 facing the box body 100. Because during the opening process of the door body 210, the transmission structure 230 can drive the vertical beam 220 to rotate towards the inner side of the door body 210, causing the vertical beam 220 to squeeze the box body 100 when the opening degree of the door body 210 is small. Therefore, by providing a flexible pad 221 on the surface of the vertical beam 220 facing the box body 100, the vertical beam 220 can contact the box body 100 via the flexible pad 221, buffering the extrusion force between the vertical beam 220 and the box body 100 and preventing the box body 100 from deforming.

[0069] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
