It can be understood that the second hinge 30 rotates around the rotating shaft 202 through the second hinge 30 and the flanging structure 50, so that the rotation and the opening and closing of the door body can be realized. The shaft sleeve 40 is sleeved outside the flanging structure 50, and a gap exists between the shaft sleeve 40 and the flanging structure 50. The gap ensures that the flange structure 50 can rotate in the shaft sleeve 40, and thus the second hinge 30 can rotate smoothly. And the shaft sleeve 40 can limit the flanging structure 50 from deviating too much during the rotation process, thereby ensuring that the second hinge 30 does not deviate. Therefore, the door body cannot deviate in the opening and closing process, and the opening and closing stability of the door body is enhanced.

The first exterior member may be the case 101, the second hinge 30 may be connected to the case 101, the rotation shaft 202 may be connected to the door body, and the door body and the rotation shaft 202 may rotate with respect to the burring structure 50, thereby opening and closing the door body.

In the present embodiment, the rotating portion 501 is configured to rotate around the rotating shaft 202 and is capable of rotating in the bushing 40. The bearing part 502 is located between the second hinge 30 and the hinge body 201, that is, the hinge assembly is installed below the door body, and when the door body is connected with the second hinge 30, the bearing part 502 can support the second hinge 30 and bear the weight of the second hinge 30 and the first external member, so as to ensure the normal rotation of the door body. The bearing portion 502 can prevent the second hinge 30 from directly contacting the hinge body 201, and can prevent interference between the rotation of the first hinge 20 and the second hinge 30.

Alternatively, when the hinge assembly is disposed below the door body, the upper end surface of the bearing portion 502 abuts against the lower end surface of the second hinge 30, and the lower end surface of the bearing portion 502 abuts against the upper end surface of the hinge body 201.

In this embodiment, the second hinge 30 and the hinge body 201 can restrict the movement of the bearing portion 502 in the vertical direction, and can increase the contact area with the bearing portion 502, thereby increasing the bearing stability of the bearing portion 502.

Alternatively, the second hinge 30 is provided with a through hole 301, the through hole 301 penetrates the second hinge 30 in the thickness direction of the second hinge 30, and both the burring structure 50 and the rotation shaft 202 penetrate the through hole 301. The bearing part 502 is annular, and the outer diameter of the bearing part 502 is greater than the inner diameter of the through hole 301, so that the second hinge 30 is abutted against the bearing part 502.

In this embodiment, the through hole 301 facilitates the arrangement of the burring structure 50 and the rotation shaft 202. The bearing part 502 is annular, so that the contact area between the bearing part 502 and the second hinge 30 in the circumferential direction can be increased, and the bearing effect of the bearing part 502 can be further increased.

The flanging structure 50 is detachably connected with the second hinge 30, so that the flanging structure 50 and the second hinge 30 can be conveniently detached and replaced

Alternatively, the flange structure 50 and the second hinge 30 can be detachably connected by screws, snaps, and the like.

Alternatively, the fixed connection manner of the flange structure 50 and the second hinge 30 may be welding or the flange structure 50 and the second hinge 30 are an integral structure.

In this embodiment, the integral structure increases the connection strength between the flanging structure 50 and the second hinge 30, ensures the movement synchronism between the flanging structure 50 and the second hinge 30, and can prevent the flanging structure 50 from being separated from the second hinge 30.

Alternatively, as shown in fig. 4, the outer surface of the rotating shaft 202 is configured with a plurality of rotating shafts and a plurality of steps, and the plurality of rotating shafts and the plurality of steps are sequentially arranged at intervals along the direction from top to bottom, wherein a corresponding step is arranged below at least one rotating shaft, the at least one rotating shaft is adapted to be rotatably connected with the door body, and the corresponding step of the at least one rotating shaft is adapted to bear the weight of the door body.

The step below each rotating shaft can bear the weight of the door body corresponding to the rotating shaft above the rotating shaft, so that the supporting strength of the rotating shaft 202 can be increased, and the service life and the stability of the rotating shaft 202 are improved. Moreover, the steps can avoid mutual interference between the door bodies corresponding to the two adjacent rotating shafts, so that the smoothness of the door opening of the refrigerator is ensured.

It should be noted that: the rotating shaft 202 is suitable for being positioned below the door body, so that the steps can bear the gravity and the load of the door body, and the rotating stability of the door body is further improved.

Alternatively, the number of the rotation shafts is the same as the number of the steps and corresponds one to one.

In this embodiment, the below of each rotation axis all corresponds and is equipped with the step for the door body that rotates to be connected with each rotation axis all can have corresponding step bearing weight, with the intensity and the normal work of assurance hinge.

Alternatively, a step is formed between adjacent two of the rotating shafts, and the outer diameters of the plurality of rotating shafts gradually increase in the top-to-bottom direction.

In this embodiment, a step is formed between two adjacent rotation shafts, and a step is formed between two adjacent rotation shafts, so that the height required by the rotation shaft 202 can be reduced, and the structure of the rotation shaft 202 is more compact. This facilitates the machining and installation of the rotating shaft 202.

Optionally, a boss is arranged between adjacent rotating shafts, the upper surface of the boss is configured with a step, and the rotating shaft is arranged below the boss. Therefore, adjacent rotating shafts are not close to each other, the distance between the door bodies corresponding to the adjacent rotating shafts can be increased, and then mutual interference among the door bodies is avoided.

When the main door 102 and the sub door 103 are opened together, the first limiting member 60 and the second limiting member 70 simultaneously perform a limiting function. Because the first limiting member 60 only limits the main door 102 and the second limiting member 70 only limits the sub-door 103, the refrigerator according to the embodiment of the present disclosure realizes light weight setting of the first limiting member 60 and the second limiting member 70, and ensures the opening angles of the main door 102 and the sub-door 103, so that the limiting of the main door 102 and the sub-door 103 is more stable.

In this embodiment, the first preset angle is the maximum angle at which the main door 102 is opened within the safety range. The second preset angle is a maximum angle at which the sub-door 103 is opened within a safe range.

Optionally, the first limiting member 60 and the second limiting member 70 are disposed opposite to each other in the vertical direction.

In this embodiment, the main door 102 and the sub-door 103 both have a certain height, and the first limiting member 60 and the second limiting member 70 are respectively disposed at two ends of the main door 102 and the sub-door 103 in the height direction. This facilitates the arrangement of the first limiting member 60 and the second limiting member 70, and the positions of the first limiting member 60 and the second limiting member 70 do not conflict with each other, so as to ensure stable limiting of the main door 102 and the sub door 103.

Alternatively, the first stopper 60 includes a stopper plate including a connecting portion 303 (hereinafter, referred to as a second connecting portion 601 for convenience of distinction) and a stopper portion 602, and the second connecting portion 601 is connected to the main door 102. The stopper 602 is connected to the second connection portion 601, and at least a part of the stopper 602 is in the same horizontal plane as the first hinge 20, and when the main door 102 is closed, the first hinge 20 and the stopper 602 are sequentially arranged in the direction from the cabinet 101 to the main door 102. When the main door 102 rotates to the first predetermined angle, the limiting portion 602 rotates to the outside of the first hinge 20 along with the main door 102, and abuts against the first hinge 20 to limit the main door 102 from rotating outwards.

In this embodiment, the second connecting portion 601 is used to connect the main door 102 and the limiting plate, so that the limiting member can rotate with the main door 102. When the stopper plate rotates along with the main door 102, the stopper portion 602 rotates outside the first hinge 20. Since at least a portion of the position-limiting portion 602 is in the same horizontal plane as the first hinge 20, when the door is rotated to the first predetermined angle, the position-limiting portion 602 and the first hinge 20 can abut against each other, which can limit the main door 102 from rotating outward.

Optionally, the refrigerator further comprises an upper hinge 701 and an upper hinge plate 702, the upper hinge 701 comprises an upper hinge body 7011 and an upper hinge 701 connected with a second rotating shaft 7012, and the upper hinge 701 of the upper hinge body 7011 is connected with the refrigerator body 101. The upper hinge plate 702 is connected to the sub-door 103, is sleeved outside the second rotating shaft 7012, and can rotate around the second rotating shaft 7012. The second limiting member 70 includes a limiting post disposed on the upper hinge plate 702, the limiting post extends toward the upper hinge 701 of the upper hinge body 7011, and when the sub-door 103 rotates to the second predetermined angle, the limiting post abuts against the upper hinge 701 to limit the sub-door 103 from continuing to rotate outward.

In this embodiment, the upper hinge 701 is connected to the casing 101, that is, the upper hinge 701 is fixed relative to the casing 101. The upper hinge plate 702 is connected to the sub door 103, that is, the upper hinge plate 702 is fixed relative to the sub door 103. The upper hinge plate 702 is sleeved on the second rotating shaft 7012 and can rotate around the second rotating shaft 7012. That is, the sub door 103 is rotated about the second rotation axis 7012 by the upper hinge plate 702. The spacing post is provided on the upper hinge plate 702 so that the spacing post can move with the sub-door 103. The limiting column extends towards the upper hinge 701 of the upper hinge body 7011, so that in the process that the limiting column rotates along with the auxiliary door 103 around the upper hinge 701, the limiting column can be abutted against the upper hinge 701, and the auxiliary door 103 can be limited from continuing to rotate outwards.

Optionally, the main door 102 is sleeved outside the second rotating shaft 7012, and the main door 102 can rotate around the second rotating shaft 7012.

In this embodiment, the main door 102 can also rotate around the second rotation axis 7012, that is, the upper end of the main door 102 and the upper end of the sub-door 103 are also coaxially disposed, so that the space occupied by the hinges can be saved, the complexity of opening the door in the door can be reduced, two sets of hinges are not required, and the cost of the refrigerator is saved. And this allows the rotation angle of the sub door 103 to be increased, so that the sub door 103 can be opened at a large angle.

Optionally, the upper hinge plate 702 is positioned between the upper hinge body 7011 and the main door 102 with the restraint posts extending upwardly. Thus, the limit column can be abutted against the upper hinge 701 in the process of rotating along with the upper hinge plate 702, so as to realize limit.

It should be noted that: the hinge of the application can be applied to a refrigerator and can also be applied to equipment such as a refrigerator and a cabinet needing to be opened.
