[0037] like Figure 1 As shown, the lower hinge 10 according to the embodiment of the utility model includes a hinge plate 1, a hinge shaft 2 and a limiting plate 3.

[0038] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the lower hinge 10 is used for the refrigerator 100, and one end of the hinge plate 1 in the length direction is suitable for being located below the box 20 of the refrigerator 100 and is suitable for being connected to the bottom wall 201 of the box 20.

The lower front beam 202 is arranged on the bottom wall 201 of the box 20 to realize the connection between the hinge plate 1 and the lower front beam 202, and then realize the connection between the hinge plate 1 and the box 20.

[0039] like Figure 1 , Figure 5 and Figure 6 As shown, the hinge shaft 2 is arranged at the other end of the hinge plate 1 in the length direction and is located on the upper surface of the hinge plate 1. The hinge shaft 2 extends in the up-down direction. The lower end surface of the door body 30 of the refrigerator 100 is provided with an axis hole, and the hinge shaft 2 is suitable for passing through the axis hole. The door body 30 of the refrigerator 100 can be pivotally mounted on the front side of the box body 20 to rotate and open or close the box body 20.

[0040] The limit plate 3 is arranged on the upper surface of the hinge plate 1 and is spaced apart from both ends of the hinge plate 1 in the length direction. The limit plate 3 is suitable for being located on the side of the box body 20 facing the door body 30 and connected to the side wall of the box body 20 facing the door body 30.

[0041] In the prior art, the door body of the refrigerator is made by a foaming process. Under the limitation of the foaming process, the lower end of the door body will be twisted and collapsed to varying degrees. The axis hole will have a positioning deviation due to the collapse of the lower end of the door body, resulting in poor installation of the door body.

[0042] like Figure 1 , Figure 5 and Figure 6 As shown, the limiting plate 3 and the side wall of the refrigerator body 20 facing the door body 30 and the side wall of the door body 30 facing the box body 20 cooperate with each other to limit each other, which can effectively ensure the verticality of the lower hinge 10, ensure the assembly dimensional accuracy of the door body 30 and the hinge shaft 2, and make the door body 30 rotate more smoothly. In addition, the overall strength of the lower hinge 10 after adding the limiting plate 3 is greater, which prevents the lower hinge 10 from bending, deformation or breaking, thereby preventing the refrigerator 100 from being unstable when placed and preventing the refrigerator 100 from tilting or tipping.

[0043] According to the lower hinge 10 of the embodiment of the utility model, the limiting plate 3 is arranged on the upper surface of the hinge plate 1 and is spaced from both ends of the hinge plate 1 in the length direction, and the limiting plate 3 is connected to the side wall of the box body 20 facing the door body 30. One end of the hinge plate 1 in the length direction is connected to the bottom wall 201 of the box body 20, and the lower end surface of the door body 30 of the refrigerator 100 is provided with an axis hole, and the hinge shaft 2 is penetrated in the axis hole. The limiting plate 3 and the side wall of the box body 20 of the refrigerator 100 facing the door body 30 and the side wall of the door body 30 facing the box body 20 cooperate and restrict each other, which can effectively ensure the verticality of the lower hinge 10, ensure the assembly dimensional accuracy of the door body 30 and the hinge shaft 2, and make the rotation of the door body 30 smoother. And the overall strength of the lower hinge 10 after adding the limiting plate 3 is greater, which avoids the lower hinge 10 from bending, deformation or breakage.

[0044] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a reinforcing rib 11 is provided on one side of the hinge plate 1 in the thickness direction away from the hinge axis 2. The reinforcing rib 11 can significantly increase the strength and rigidity of the hinge plate 1, especially at the places on the hinge plate 1 that need to withstand greater pressure, torsion or bending force. The reinforcing rib 11 helps to maintain the stability and reliability of the hinge plate 1 and prevent deformation or damage caused by external forces. The reinforcing rib 11 can also optimize the stress distribution in the hinge plate 1 and reduce the stress unevenness caused by the difference in wall thickness. It helps to prevent the hinge plate 1 from being damaged due to stress concentration and improve the overall performance of the hinge plate 1.

[0045] Furthermore, if Figure 1 and Figure 2 As shown, the reinforcing rib 11 includes a first reinforcing rib 111. The hinge plate 1 is provided with a mounting hole 12 for connecting with the box body 20, and the first reinforcing rib 111 is arranged around the mounting hole 12. The first reinforcing rib 111 can optimize the stress distribution at the mounting hole 12 and reduce the stress unevenness caused by the difference in wall thickness. This helps to prevent the hinge plate 1 from being damaged due to stress concentration and improve the overall performance of the hinge plate 1.

[0046] Furthermore, if Figure 1 and Figure 2As shown, there are multiple mounting holes 12, and at least some of the mounting holes 12 are surrounded by the first reinforcing ribs 111. The first reinforcing ribs 111 can optimize the stress distribution at the mounting holes 12 and reduce the stress unevenness caused by the difference in wall thickness. It is helpful to prevent the hinge plate 1 from being damaged due to stress concentration and improve the overall performance of the hinge plate 1. The reinforcing ribs 11 also include second reinforcing ribs 112, and at least some of the adjacent two first reinforcing ribs 111 are connected with the second reinforcing ribs 112. The second reinforcing ribs 112 can significantly increase the strength and rigidity between the first reinforcing ribs 111, and the second reinforcing ribs 112 can significantly increase the strength and rigidity between the mounting holes 12 provided with the first reinforcing ribs 111. When the hinge plate 1 needs to withstand greater pressure, torsion or bending force, the mounting holes 12 can be better protected to avoid deformation or cracking at the mounting holes 12, thereby reducing the maintenance and replacement costs caused by deformation, cracking or damage.

[0047] Furthermore, if Figure 1 and Figure 2 As shown, a reinforcing protrusion 13 is provided on the lower surface of the hinge plate 1 at a position corresponding to the hinge shaft 2, which can increase the strength and rigidity of the hinge plate 1 at the hinge shaft 2. When the hinge plate 1 needs to withstand a large pressure, torsion or bending force, the hinge shaft 2 can be better protected to avoid deformation or cracking at the hinge shaft 2, thereby reducing the maintenance and replacement costs caused by deformation, cracking or damage. The reinforcing rib 11 also includes a third reinforcing rib 113, and the two ends of the third reinforcing rib 113 in the length direction are respectively connected to the first reinforcing rib 111 and the reinforcing protrusion 13. The first reinforcing rib 111 and the reinforcing protrusion 13 can realize force transmission when subjected to external force impact. When the hinge plate 1 needs to withstand a large pressure, torsion or bending force, the mounting hole 12 and the hinge shaft 2 can be better protected to avoid deformation or cracking at the mounting hole 12 and the hinge shaft 2, thereby reducing the maintenance and replacement costs caused by deformation, cracking or damage.

[0048] In some embodiments of the present invention, Figure 1 and Figure 2As shown, along the length direction of the hinge plate 1, the hinge plate 1 includes a mounting and positioning plate 14, a connecting plate 15 and a matching plate 16 connected in sequence. The mounting and positioning plate 14 is suitable for being located below the box body 20 of the refrigerator 100 and is suitable for being connected to the bottom wall 201 of the box body 20. The end of the connecting plate 15 that is away from the mounting and positioning plate 14 extends upward. In the up-down direction, the matching plate 16 is located above the mounting and positioning plate 14, and the hinge shaft 2 is provided on the upper surface of the matching plate 16. It can be understood that the positioning plate 14, the connecting plate 15 and the matching plate 16 can be installed to form a step surface in the up and down directions, which can increase the connection effect of the connecting plate 15 and the limiting plate 3 with the side wall of the box body 20 facing the door body 30. The limiting plate 3 and the connecting plate 15 cooperate with the side wall of the box body 20 of the refrigerator 100 facing the door body 30 and the side wall of the door body 30 facing the box body 20 to restrict each other, which can effectively ensure the verticality of the lower hinge 10, ensure the assembly dimensional accuracy of the door body 30 and the hinge shaft 2, so that the rotation of the door body 30 is smoother.

[0049] In some embodiments of the present invention, the lower hinge 10 is a die-cast integral part, which can be formed into a complex shape, and complex reinforcing ribs 11 can be designed to increase the rigidity of the lower hinge 10 and facilitate the overall strength of the limit plate 3 and the hinge plate 1.

[0050] In some embodiments of the present invention, the hinge plate 1 and the box body 20 are suitable for being connected by fasteners. The connection between the hinge plate 1 and the box body 20 is relatively simple and reliable, and the connection between the hinge plate 1 and the box body 20 is detachable, which is convenient for replacing and repairing the lower hinge 10.

[0051] In some embodiments of the present invention, the lower hinge 10 is an aluminum alloy part. The lower hinge 10 is light in weight and high in strength, and can withstand large loads and impact forces. The lower hinge 10 has a better supporting effect on the body 20 and the door body 30 of the refrigerator 100.

[0052] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the lower hinge 10 further includes a roller 4, which is rotatably disposed below the hinge plate 1 and located at an end of the hinge plate 1 in the length direction away from the hinge shaft 2. The refrigerator 100 can be easily moved on the ground.

The roller 4 can also cope with the uneven placement of the refrigerator 100 caused by uneven ground at home, so that the refrigerator 100 remains stable.

[0053] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the lower hinge 10 also includes an adjusting foot 5, which is arranged below the hinge plate 1 and is used to adjust the distance between the lower surface of the adjusting foot 5 and the hinge plate 1. The adjusting foot 5 can adjust the height of the refrigerator 100, thereby ensuring that the refrigerator 100 can remain level even on an uneven ground. The horizontal placement of the refrigerator 100 helps to ensure that the refrigeration system in the refrigerator 100 works properly, while preventing the items inside the refrigerator 100 from sliding and tipping over. By adjusting the adjusting foot 5, the refrigerator 100 is kept balanced, the noise and vibration that may be generated by the refrigerator 100 during operation can be reduced, and the comfort of use of the refrigerator 100 can be improved.
