[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] like Figs. 1-2 As shown, a deformation-resistant door seal stability structure is disposed between the refrigerator body 100 and the refrigerator door 200. Specifically, the door seal stability structure includes a door seal air cavity 20, a connecting beam 30 disposed on the lower side of the door seal air cavity 20, and a slot mounting component 8 disposed on the lower side of the connecting beam 30. The connecting beam 30 is integrally formed and disposed on the lower side of the door seal air cavity 20, and the slot mounting component 8 is integrally formed and disposed on the lower side of the connecting beam 30.

[0032] An S-shaped rib 5 is provided inside the door sealing air cavity 20. One end of the S-shaped rib 5 is connected to the rib at the top of the door sealing air cavity 20, and the other end of the S-shaped rib 5 is connected to the connecting beam 30. Specifically, the connection between the S-shaped rib 5 and the rib at the top of the door sealing air cavity 20, and the connection between the S-shaped rib 5 and the connecting beam 30, can both be integrally formed.

[0033] S-shaped rib 5 divides the door sealing air chamber 20 into left air chamber group 40 and right air chamber group 50;

[0034] The left air chamber group 40 is provided with a transverse rib 401, which divides the left air chamber group 40 into a magnetic strip bag 2 and an external air bag 10; specifically, the right side of the transverse rib 401 is integrally formed and connected to the S-shaped rib 5.

[0035] The right air chamber group 50 is provided with a first rib 6. One end of the first rib 6 is connected to the S-shaped rib 5, and the other end of the first rib 6 is connected to the connecting beam 30. The connection between the first rib 6 and the S-shaped rib 5, and the connection between the first rib 6 and the beam 30 can both be integrally formed.

[0036] The first rib 6 divides the right air chamber group 50 into a side air bladder 4 and a square hole 7; specifically, the side air bladder 4 is located above the square hole 7.

[0037] The door seal stability structure, when subjected to uneven force during door seal transportation, uses the left corner of the outer airbag 10 to fix the left and right forces on the door seal, making it less prone to deformation. The C-shaped connection on the side airbag 4 allows the door seal to maintain better elasticity and telescopic distance. At the same time, when the refrigerator door spacing is uneven, the door seal height is increased, allowing the magnetic strip end to better fit the cabinet. During opening and closing, the S-shaped rib 5 increases the stress rib and provides elasticity, ensuring the integrity of the door seal structure and preventing the door seal from deforming due to magnetic force. This ensures that the door seal stability structure can have a higher fitting height and, under certain longitudinal deformation, has elasticity to ensure recovery to its original shape, thereby achieving high compensation of the door seal and compensating for the offset caused by magnetic force.

[0038] like Figs. 1-2 As shown, in some embodiments of this utility model, the left side of the external airbag 10 has a third rib 101, one end of the third rib 101 is bent upward to form an extension rib 102, and the other end of the third rib 101 is connected to the connecting crossbeam 30; the end of the extension rib 102 away from the third rib 101 is connected to the transverse rib 401.

[0039] Specifically, the third stiffener 101 is integrally formed and connected to the connecting beam 30; the extension stiffener 102 is integrally formed and connected to the transverse stiffener 401.

[0040] The third rib 101 is C-shaped. Specifically, the upper and lower sides of the third rib 101 are straight, and the right side of the third rib 101 is arc-shaped, so that the lower left corner of the outer airbag 10 has a square corner structure, which fixes the door seal stability structure to be subjected to left and right forces, thereby making the door seal stability structure less prone to deformation.

[0041] like Figs. 1-2 As shown, in some embodiments of this utility model, a magnetic stripe is provided inside the magnetic stripe pouch 2.

[0042] like Figs. 1-2 As shown, in some embodiments of this utility model, the side airbag 4 has a second rib 41 on the upper right side, one end of the second rib 41 is connected to the magnetic strip 2, and the other end of the second rib 41 is connected to the first rib 6.

[0043] The connection between the second rib 41 and the magnetic stripe 2, and the connection between the second rib 41 and the first rib 6, can both be integrally molded.

[0044] like Figs. 1-2 As shown, in some embodiments of this utility model, the first rib 6 and the second rib 41 are both C-shaped;

[0045] The first rib 6 and the second rib 41 of the C-shaped structure can provide a large amount of deformation and provide compression buffer space when the door seal stability structure is compressed or stretched, which is beneficial to improving the service life of the door seal stability structure.

[0046] like Figs. 1-2 As shown, in some embodiments of this utility model, the slot mounting component 8 has an artificial airbag hole 81 inside.

[0047] Specifically, the biomimetic airbag opening 81 includes a top biomimetic opening 82 and a bottom biomimetic opening 83 that are connected from top to bottom;

[0048] The cross-section of the top biomimetic hole 82 is hourglass-shaped;

[0049] The cross-section of the bottom bionic hole 83 is an inverted triangle;

[0050] The biomimetic gasbag hole 81 has two components: the top biomimetic hole 82 and the bottom biomimetic hole 83. The overall structure is modeled after the human forearm, with a wider upper end and a narrower lower end, which makes the door seal stability structure fit more tightly with the groove of the refrigerator door 200.

[0051] like Figs. 1-2 As shown, in some embodiments of this utility model, a reinforcing rib 301 is provided on the upper side of the connecting beam 30; the presence of the reinforcing rib 301 makes the connecting beam 30 of the door seal stability structure less prone to deformation, thereby improving its service life.

[0052] In this utility model, the door seal stability structure includes a magnetic strip, a magnetic strip bladder 2, a side air bladder 4, an S-shaped rib 5, a first rib 6, a square hole 7, a slot mounting piece 8, and an outer air bladder 10. During the transportation of the door seal, the square hole 7 can prevent the rubber sleeve from deforming under lateral force. When the refrigerator door 200 and the door seal stability structure are fitted together, the biomimetic design at the slot mounting piece 8 can compensate for the problem of loose fit and ensure the reliability of assembly and sealing.

[0053] When the refrigerator door is closed, the door seal stability structure and the refrigerator body 100 are attracted to the refrigerator body 100 by the magnetic force of the magnetic strip inside the magnetic strip bladder 2. Since the outer air bladder 10 will be stretched when closed, the double air chambers added to the door seal at this time, while ensuring the height, the S-shaped rib 5 on the left side of the side air bladder 4 can provide longitudinal elasticity to ensure that the structure does not deform, thereby compensating for the deformation caused by the magnetic force.
