[0078] In some embodiments, a first mounting base 84 is further included, and the first mounting base 84 is located between the first cylinder 81 and the cabinet 1. The first mounting pin 83 passes through the first mounting base 84 and also fixes the first mounting base 84 to the cabinet 1. The present disclosure can fix one end of the first cylinder to the cabinet of the refrigerator by providing the first mounting base, so that the components provided on the cabinet drive the first door to move relative to the first door.

[0079] In some embodiments, when the first door 2 and the second door 3 are closed, the axes of the first cylinder 81, the first push rod 82, the first connecting member 10, and the first rotating shaft 71 are all located on the same straight line. At this time, the first cylinder assembly 8 and the first rotating shaft 71 are at a dead center position. This arrangement ensures that when the first door is closed, the pushing direction of the first cylinder is toward the axis of the first rotating shaft, and does not drive the first connecting member to rotate, thereby not driving the first rotating shaft to rotate, ensuring a stable state in the closed state without causing the first door to move.

[0080] In some embodiments, one end of the first connecting rod 61 is connected to the surface of the first door body 2 facing the first crossbeam 41. A first clearance groove 47 is provided on the surface of the first crossbeam 41 facing the first door body 2. The first clearance groove 47 can accommodate at least a portion of the structure of the first connecting rod 61. The present disclosure also provides a first clearance groove provided on the first crossbeam toward the first connecting rod, so that at least a portion of the structure of the first connecting rod can be accommodated in the first clearance groove when the first door body is closed, thereby ensuring that the first door body can fit more tightly with the box body, and are combined together to improve the sealing performance.

[0081] In some embodiments, a second connecting rod 62 and a second rotating shaft 72 are further included, wherein one end of the second connecting rod 62 is connected to the second door body 3 and the other end is connected to the second rotating shaft 72, the third axial end of the second rotating shaft 72 is connected to the first crossbeam 41, and the fourth axial end of the second rotating shaft 72 is connected to the second crossbeam 42. The second connecting rod 62 can be driven by the rotation of the second rotating shaft 72 to move and thereby drive the second door body 3 to move. The present disclosure can transmit the driving force through the second connecting rod, and the second rotating shaft drives the second connecting rod to move by rotating, thereby pushing the second door body to move. Its movement path is that the third side end slides along the first slide rail, while the other parts produce translational + rotational movement, and the end of the second connecting rod connected to the second door body rotates around the second rotating shaft. The second connecting rod is equivalent to a radius rod.

[0082] In some embodiments, a third mounting hole 45 is provided on the first crossbeam 41, and a fourth mounting hole 46 is provided on the second crossbeam 42. The third axial end of the second rotating shaft 72 can be inserted into the third mounting hole 45, and the fourth axial end can be inserted into the fourth mounting hole 46. The present disclosure also uses the third mounting hole on the second crossbeam and the fourth mounting hole on the second crossbeam to accommodate the insertion and position limitation of both ends of the second rotating shaft. The second rotating shaft is mainly supported by the fourth mounting hole at the lower end, while the upper end of the second rotating shaft passes through the third mounting hole and engages with the second connecting member (latch).

[0083] In some embodiments, a second cylinder assembly 9 is further included, which can drive the second rotating shaft 72 to rotate. The present disclosure can provide a driving force to drive the second rotating shaft to rotate, thereby driving the second connecting rod to move the second door to open the refrigerator.

[0084] In some embodiments, a second connecting member 11 is further included, and the second connecting member 11 is connected to the second rotating shaft 72. One end of the second cylinder assembly 9 is connected to the second connecting member 11, and the other end is fixed to the box body 1. The driving force of the second cylinder assembly 9 is transmitted to the second rotating shaft 72 through the second connecting member 11. The second connecting member is preferably a latch. The present disclosure can connect with the second cylinder assembly through the provision of the second connecting member to convert the driving force of the second cylinder assembly into the rotation of the second connecting member, thereby driving the rotation of the second rotating shaft, and finally driving the rotation of the second connecting rod, thereby driving the second door body to open or close the refrigerator.

[0085] In some embodiments, the second cylinder assembly 9 includes a second cylinder body 91, a second push rod 92, and a second mounting pin 93. The second cylinder body 91 is fixed to the housing 1 via the second mounting pin 93. One end of the second push rod 92 extends into the second cylinder body 91, and the other end is connected to the second connecting member 11. Through the arrangement of the second cylinder assembly, the second rotating shaft, and the second connecting rod, the fourth side end of the second door body can be effectively driven to move. When the door body is opened, the fourth side end of the second door body is driven to move in a direction away from the housing, while the third side end is located between the first and second cross beams, achieving a tight closure effect. When opened, the door body does not have the large rotation radius of existing refrigerator doors, which may cause interference with the human body when the space is small.

[0086] In some embodiments, a second mounting base 94 is further included, and the second mounting base 94 is located between the second cylinder 91 and the cabinet 1. The second mounting pin 93 passes through the second mounting base 94 and also fixes the second mounting base 94 to the cabinet 1. The present disclosure can fix one end of the second cylinder to the cabinet of the refrigerator by providing the second mounting base, thereby achieving the effect of the component provided on the cabinet driving the second door to move relative to it.

[0087] In some embodiments, when the first door 2 and the second door 3 are closed, the axes of the second cylinder 91, the second push rod 92, the second connecting member 11, and the second rotating shaft 72 are all located on the same straight line. At this time, the second cylinder assembly 9 and the second rotating shaft 72 are at a dead center position. This arrangement ensures that when the second door is closed, the pushing direction of the second cylinder is toward the axis of the second rotating shaft, and does not drive the second connecting member to rotate, thereby not driving the second rotating shaft to rotate, ensuring a stable state in the closed state without causing the second door to move.

[0088] In some embodiments, one end of the second connecting rod 62 is connected to the surface of the second door body 3 facing the first crossbeam 41. A second clearance groove 48 is provided on the surface of the first crossbeam 41 facing the second door body 3. The second clearance groove 48 can accommodate at least a portion of the structure of the second connecting rod 62. The present disclosure also provides a second clearance groove provided on the first crossbeam toward the second connecting rod, so that at least a portion of the structure of the second connecting rod can be accommodated in the second clearance groove when the second door body is closed, thereby ensuring that the second door body can fit more tightly with the box body, combining them together and improving the sealing performance.

[0089] The present disclosure also provides a refrigerator, which includes the refrigerator door opening device of any of the preceding items.

[0090] The present invention realizes the opening of the refrigerator door from both sides through the rotation of the rotating shafts on both sides of the refrigerator and the connecting rod mechanism. At the same time, when the door is closed, the top cylinder and the rotating shaft are in the dead point position and the door is locked. The sealing of the refrigerator is also improved by arranging seals on the movable guide rails of the box body and the door body.

[0091] When the user opens the door, they use any part of their body to move the left and right outer handles, giving the door an initial rotational velocity V. The cylinder assembly then drives the shaft mechanism to continue rotating until the door opens. This process requires no additional external force to open the door. In addition to using a cylinder at the top of the housing, this embodiment also allows for gear meshing to open and close the door.

[0092] The above are merely preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure. The above are merely preferred embodiments of the present disclosure. It should be noted that those skilled in the art may make various improvements and modifications without departing from the technical principles of the present disclosure, and such improvements and modifications shall also be considered within the scope of protection of the present disclosure.
