[0038] The hinge assembly provided by the embodiment of the present disclosure is adopted, by providing the first mounting portion 100 and the second mounting portion 200, the second mounting portion 200 is threadedly connected to the rotating shaft 300 inside the first mounting portion 100. When it is necessary to adjust the left and right position of the second mounting portion 200 relative to the first mounting portion 100, by rotating the rotating shaft 300, the second mounting portion 200 moves upward along the axis of the rotating shaft 300 under the action of the threaded connection, thereby accurately controlling the adjustment distance of the second mounting portion 200 relative to the first mounting portion 100, improving the adjustment accuracy, and further improving the adjustment efficiency.

[0039] Optionally, the first mounting portion 100 includes: a first mounting plate 110 and a supporting fold 120. Two supporting folds 120 are provided, one of the two supporting folds 120 is connected to one side of the first mounting plate 110, and the other is connected to the other side opposite to the first mounting plate 110.

In this way, the first mounting portion 100 is divided into the first mounting plate 110 and the supporting fold 120, and is assembled with the refrigerator through the first mounting plate 110. The two supporting folded edges 120 protrude along the opposite side edges of the first mounting plate 110, respectively, forming an installation space between the two supporting folded edges 120, and the rotating shaft 300 is rotatably installed between the two supporting folded edges 120. The two ends of the rotating shaft 300 are rotatably connected to the two supporting folded edges 120, respectively, thereby improving the stability of the rotating shaft 300 and simultaneously improving the stability of the rotational connection between the second mounting portion 200 and the first mounting portion 100.

[0040] Optionally, the first mounting plate 110 is a rectangular plate-shaped structure, and the two supporting folds 120 are respectively arranged at the long sides of the first mounting plate 110. In this way, the rectangular first mounting plate 110 can better adapt to the installation of the refrigerator, and the two supporting folds 120 are respectively arranged at the long sides of the first mounting plate 110, which can improve the strength of the two supporting folds 120, thereby further improving the support stability of the rotating shaft 300.

[0041] Optionally, the two supporting folds 120 are long strip-shaped plate structures arranged at the long sides of the first mounting plate 110 .

[0042] Optionally, the two supporting folds 120 extend along the long sides of the first mounting plate 110 and protrude from the upper side of the first mounting plate 110. In this way, the mounting plate can be prevented from interfering with the rotation of the second mounting plate 210.

[0043] Optionally, the planes where the two support folds 120 are located are perpendicular to the plane where the first mounting plate 110 is located. In this way, the two support folds 120 are vertically connected to the first mounting plate 110, and the two support folds 120 are not easily offset when subjected to force, thereby improving the stability of the two support folds 120.

[0044] Optionally, the two support folds 120 are provided with shaft holes at positions corresponding to the two ends of the rotating shaft 300, and the two ends of the rotating shaft 300 respectively penetrate the corresponding shaft holes and are rotatably connected to the two support folds 120. In this way, the stability of the rotatable connection between the rotating shaft 300 and the two support folds 120 can be further improved.

[0045] It can be understood that both ends of the rotating shaft 300 are rotatably mounted through structures such as sleeves or bearings, which will not be elaborated here.

[0046] Optionally, one end of the rotating shaft is provided with a handle groove 320. In this way, a tool such as a wrench can be inserted into the handle groove 320 to drive the rotation of the rotating shaft, which is convenient for user operation.

[0047] Exemplarily, the handle groove 320 may be a regular hexagonal groove, a plum blossom groove, a cross groove or the like.

[0048] Optionally, a first mounting hole 130 is provided on the first mounting plate 110, and the length of the first mounting hole 130 along the length direction of the support fold 120 is greater than the diameter of the mounting bolt. In this way, the first mounting plate 110 is mounted on the refrigerator by the mounting bolts and the first mounting hole 130, so that the first mounting part 100 is assembled with the refrigerator. The length of the first mounting hole 130 is set to be greater than the diameter of the mounting bolt, so that the mounting bolt can be adjusted in the first mounting hole 130 along the length direction of the support fold 120, thereby adjusting the installation position of the first mounting part 100 on the refrigerator, thereby improving the user experience.

[0049] Optionally, along the length direction of the support flange 120, the length of the first mounting hole 130 is greater than twice the diameter of the mounting bolt.

[0050] Optionally, along the length direction of the supporting flange 120, the length of the first mounting hole 130 is equal to three times the diameter of the mounting bolt. In this way, when the length of the first mounting hole 130 is large, the first mounting hole 130 occupies too much space of the first mounting plate 110, resulting in a decrease in the self-strength of the first mounting plate 110. Therefore, setting the length of the first mounting hole 130 equal to three times the diameter of the mounting bolt can ensure both the adjustment space of the mounting bolt and the self-strength of the first mounting plate 110.

[0051] Optionally, along the axial direction of the rotating shaft 300, the length of the threaded protrusion 310 provided on the outer peripheral wall of the rotating shaft 300 is greater than or equal to one third of the length of the rotating shaft 300. In this way, when it is necessary to adjust the position of the second mounting portion 200 relative to the first mounting portion 100, the adjustment distance of the second mounting portion 200 can be increased to meet the diverse adjustment needs of users.

[0052] Optionally, along the axial direction of the rotating shaft 300, the length of the threaded protrusion 310 provided on the outer peripheral wall of the rotating shaft 300 is equal to one third of the length of the rotating shaft 300.

In this way, the second mounting portion 200 is divided into the second mounting plate 210 and the two supporting flanges 220, and the two supporting flanges 220 are respectively arranged at the two opposite sides of the second mounting plate 210, and the two supporting flanges 220 are sleeved on the outer periphery of the rotating shaft 300 and are rotatably connected to the rotating shaft 300, thereby improving the stability of the threaded connection between the second mounting portion 200 and the rotating shaft 300. By threading one or both of the two supporting flanges 220 to the rotating shaft 300 , the position of the second mounting portion 200 can be adjusted when the rotating shaft 300 is rotated, so that the second mounting portion 200 moves upward along the axis of the rotating shaft 300 .

[0054] Optionally, the second mounting plate 210 is a rectangular plate structure, so that the second mounting plate 210 is better adapted to the installation of the refrigerator.

[0055] Optionally, the second mounting plate 210 is vertically arranged, and the two supporting flanges 220 are respectively arranged on two vertical sides of the second mounting plate 210 and protrude vertically from the lower side of the second mounting plate 210.

In this way, the support sleeve 221 can increase the area of ​​the threaded connection with the rotating shaft 300, thereby improving the stability of the threaded connection between the support flange 220 and the rotating shaft 300.

[0059] Optionally, the support sleeve 221 and the support flange 220 are integrally formed into a structure, so that the connection stability between the support sleeve 221 and the support flange 220 is higher, and the support flange 220 can move upward along the axis of the rotating shaft 300 more stably.

[0060] Combination Figure 1 As shown, in one embodiment, when one of the two supporting flanges 220 is threadedly connected to the rotating shaft 300, a threaded protrusion 310 is provided on the outer peripheral wall of the rotating shaft 300 corresponding to the supporting flange 220, and a threaded groove 222 is provided on the inner wall corresponding to the position of the supporting flange 220 sleeved on the outside of the rotating shaft 300, and the threaded protrusion 310 is engaged with the threaded groove 222.

[0061] In the embodiment of the present disclosure, by threading one of the two support flanges 220 with the rotating shaft 300, the support flange 220 connected thereto can be driven to move upward along the axis when the rotating shaft 300 rotates, thereby driving the second mounting portion 200 to move upward along the axis of the rotating shaft 300 for adjustment. A threaded protrusion 310 is provided at the corresponding position of the outer peripheral wall of the rotating shaft 300, and a threaded groove 222 is provided on the inner wall of the threaded support flange 220.

[0063] Combination Figure 4As shown, in another embodiment, when both supporting flanges 220 are threadedly connected to the rotating shaft 300, the outer peripheral wall of the rotating shaft 300 corresponding to the two supporting flanges 220 is provided with a threaded protrusion 310, and the inner wall corresponding to the position of the two supporting flanges 220 sleeved on the outer side of the rotating shaft 300 is provided with a threaded groove 222, and the threaded protrusion 310 is meshed with the corresponding threaded groove 222. In this way, the inner wall of the two supporting flanges 220 is provided with a threaded groove 222, and the outer peripheral wall of the rotating shaft 300 is provided with a threaded protrusion 310 at the position corresponding to the two supporting flanges 220, so that the two supporting flanges 220 are threadedly connected to the rotating shaft 300. When the rotating shaft 300 rotates, through the cooperation of the threaded protrusion 310 and the threaded groove 222, the two supporting flanges 220 are driven to move upward along the axis at the same time in a more stable manner, thereby improving the stability of the second mounting portion 200 during adjustment.

[0064] Exemplarily, in the embodiment of the present disclosure, the inner walls of the through holes opened on the inner sides of the two supporting flanges 220 are provided with threaded grooves 222, and the outer peripheral wall areas of the rotating shaft 300 corresponding to the two supporting flanges 220 are provided with threaded protrusions 310, and the length of the threaded protrusions 310 provided in the outer peripheral wall area of ​​the rotating shaft 300 corresponding to each supporting flange 220 is equal to one third of the length of the rotating shaft 300.

[0066] Combination Figure 5 As shown, in some embodiments, a guide rod 140 is further provided on the inner side of the two support folds 120, and the two support flanges 220 are both movably sleeved on the outer side of the guide rod 140. The two support folds 120 are both provided with guide grooves 121 at the positions corresponding to the two ends of the guide rod 140, and the two ends of the guide rod 140 are respectively movably embedded in the corresponding guide grooves 121. In this way, when the second mounting part 200 rotates relative to the first mounting part 100, the rotation of the second mounting part 200 is guided by the cooperation of the guide rod 140 and the guide groove 121, so that the rotation of the second mounting part 200 is more stable.

[0067] Optionally, the guide groove 121 is an arc groove, and the arc of the guide groove 121 is one-half π. In this way, since the guide groove 121 can not only guide the guide rod 140, but also form a limit function, when the second mounting part 200 rotates to the maximum angle relative to the first mounting part 100, the guide rod 140 also moves to the end of the guide groove 121, thereby preventing the second mounting part 200 from being damaged due to excessive rotation.

[0068] Optionally, the guide rod 140 is located below the rotating shaft 300, and the lower ends of the two supporting flanges 220 are respectively sleeved on different areas of the outer circumference of the guide rod 140. In this way, when the second mounting portion 200 rotates relative to the first mounting portion 100, the two supporting flanges 220 rotate around the connecting shaft, and provide rotation support through the rotating shaft 300. At the same time, the lower ends of the two supporting flanges 220 drive the guide rod 140 to slide in the guide groove 121, thereby guiding the rotation of the second mounting portion 200.

[0069] Optionally, a support seat 150 is further provided between the two support folds 120, a guide hole penetrating from top to bottom is provided in the middle area of ​​the support seat 150, a support rod 160 is provided on the lower side wall of the guide rod 140, and the lower end of the support rod 160 passes through the guide hole. In this way, by providing the cooperation of the support seat 150 and the support rod 160, the movement of the guide rod 140 is further limited and guided, and when the second mounting portion 200 rotates relative to the first mounting portion 100, the rotation stability of the second mounting portion 200 is higher.

[0070] Optionally, an upper pressing seat 161 is arranged on the outer side of the support rod 160, a lower pressing seat 151 is arranged on the upper end of the guide hole, the lower end of the support rod 160 passes through the lower pressing seat 151 and the guide hole, a compression spring 170 is arranged between the upper pressing seat 161 and the lower pressing seat 151, the compression spring 170 is sleeved on the outer side of the support rod 160, and the upper end of the compression spring 170 is connected to the lower side wall of the upper pressing seat 161, and the lower end of the compression spring 170 is connected to the upper side wall of the support seat 150. In this way, by sleeve-arranging the compression spring 170 on the outer side of the support rod 160, and limiting the compression spring 170 by the upper pressing seat 161 and the lower pressing seat 151. When the second mounting part 200 is rotated and opened relative to the first mounting part 100, the guide rod 140 at the lower end is driven to move upward, and the guide rod 140 drives the support rod 160 connected to the lower side wall to move upward, thereby stretching the compression spring 170 sleeved on the outside of the support rod 160. Under the tension of the compression spring 170, the guide rod 140 has a tendency to move downward, so that the second mounting part 200 has a tendency to reset. At the same time, under the action of the support rod 160 and the compression spring 170, the threaded connection between the two support flanges 220 and the rotating shaft 300 is more stable. When the second mounting part 200 rotates, the two support flanges 220 are not easy to rotate relative to the rotating shaft 300, reducing the risk of displacement of the two support flanges 220 relative to the rotating shaft 300.

[0071] Combination Figure 6 As shown, in some embodiments, a refrigerator includes: the hinge assembly of the above embodiment.

[0072] Optionally, the refrigerator further includes: a cabinet body 400 and a door body 500. The first mounting portion 100 is connected to the cabinet body 400, and the second mounting portion 200 is connected to the door body 500. When the second mounting portion 200 moves relative to the first mounting portion 100, the door body 500 moves along the left-right direction with the second mounting portion 200. In this way, when it is necessary to adjust the position of the door body 500 relative to the cabinet body 400 in the left-right direction, it can be achieved by adjusting the position of the second mounting portion 200 relative to the first mounting portion 100.

[0073] In the embodiment of the present disclosure, the first mounting portion 100 is connected to the cabinet body 400 of the refrigerator, and the second mounting portion 200 is connected to the door body 500 of the refrigerator, thereby improving the accuracy of left-right position adjustment of the door body 500 relative to the cabinet body 400 and improving the adjustment efficiency of the left-right uneven door body 500 of the refrigerator.
