[0028] The following is combined with Figure 1 To the attached Figure 8 The present application is further described in detail with reference to the accompanying drawings.

[0029] In order to solve the problems of complex manufacturing process and low efficiency of assembly process of current refrigerator hinges, the present application provides a refrigerator, including a cabinet 1, a door body 2, and a hinge assembly 3 for rotatably connecting the door body 2 to the cabinet 1. The cabinet 1 is used to accommodate food or other items, and the door body 2 is used to open or close the cabinet 1. The hinge assembly 3 connects the door body 2 and the cabinet 1 so that the door body 2 can rotate relative to the cabinet 1 to realize the functions of opening and closing.

[0030] The hinge assembly 3 includes a groove body 305 provided on one of the box body 1 and the door body 2, and an axis body 301 provided on the other. The groove body 305 includes a first groove body 307 and a second groove body 306. The axis body 301 includes a first axis body 304 cooperating with the first groove body 307 and a second axis body 303 cooperating with the second groove body 306. During the process of rotating the door body 2 to open or rotate to close, the first axis body 304 moves along the first groove body 307, and at the same time, the second axis body 303 moves along the second groove body 306 to drive the door body 2 to move according to a preset trajectory, thereby controlling the movement trajectory of the door body 2, avoiding interference between the door body 2 and external environmental parts, and broadening the use scenarios of the refrigerator, such as making the refrigerator suitable for embedded use scenarios.

[0031] In one specific embodiment, the groove 305 is disposed on the door body 2, and correspondingly, the shaft 301 is disposed on the box body 1. Specifically, the hinge assembly 3 includes a fixed hinge fixed to the box body 1 and a movable hinge fixed to the door body 2. The groove 305 is disposed on the movable hinge, and the shaft 301 is disposed on the fixed hinge. Of course, this is not limiting. In other embodiments, the groove 305 may also be disposed on the box body 1, that is, on the fixed hinge, and correspondingly, the shaft 301 is disposed on the door body 2, that is, on the movable hinge.

[0032] In some optional embodiments, there is a first angle between the first groove body 307 and the second groove body 306, and the first groove body 307 is connected to the second groove body 306; the first groove body 307 and the second groove body 306 are connected to each other, which reduces the interference between the shaft body 301 and the periphery of the groove body 305 during the installation process, and at the same time reduces the friction between the shaft body 301 and the groove body 305 during use, so that the hinge assembly 3 rotates more flexibly.

[0033] Specifically, the length of the first groove body 307 is greater than the length of the second groove body 306. During the process of rotating the refrigerator door body 2 to open or close, the first shaft body 304 moves unidirectionally along the first groove body 307, allowing the door body 2 to rotate within a larger angle range relative to the cabinet body 1, thereby increasing the maximum opening angle of the door body.

[0034] Specifically, the first slot body 307 includes a first end, a second end and a slot section located between the first end and the second end. When the door body 2 is in a closed state, the first shaft body 304 is located at the first end. During the process of the door body 2 rotating to open from the closed state, the first shaft body 304 moves along the slot section toward the second end; when the door body 2 rotates to open to the maximum angle, the first shaft body 304 is located at the second end.

[0035] The groove section has a connecting port 309, and one end of the second groove body 306 is connected to the connecting port 309. The diameter of the connecting port 309 is smaller than the diameter of the second shaft body 303, so as to ensure that the second shaft body 303 will not enter the first groove body 307 through the connecting port 309 when moving in the second groove body 306, so as to ensure that the second shaft body 303 is always located in the second groove body 306, thereby improving the stability of the movement of the door body 2.

[0036] It should be noted that the diameter of the communication opening 309 refers to the width of the communication opening 309 in the length extension direction of the groove section.

[0037] A reinforcement structure is provided at the connection between the first slot body 307 and the second slot body 306 to improve the strength and stability of the connection, thereby ensuring that the connection will not be damaged due to stress concentration during frequent rotation of the door body 2 .

[0038] Specifically, in one embodiment of the present application, the thickness of the groove wall at the connection between the first groove body 307 and the second groove body 306 is increased, that is, the thickness of the groove wall of the groove body 305 is increased, so that the thickness of the groove wall of the groove body 305 at the connection between the first groove body 307 and the second groove body 306 is greater than the thickness of the groove wall at other positions of the first groove body 307 and the second groove body 306, thereby increasing the strength of the connection between the first groove body 307 and the second groove body 306. In addition, a high-strength composite material such as carbon fiber or glass fiber can be embedded in the connection between the first groove body 307 and the second groove body 306 to improve the bearing capacity of the connection.

[0039] Specifically, along the direction from the first end of the first slot body 307 toward the second end, the slot segments sequentially include a first slot segment 3071, a second slot segment 3072, and a third slot segment 3073. The second slot segment 3072 is provided with a communication opening 309. The first slot segment 3071 and the third slot segment 3073 are arcuate slot segments. The second slot body 306 includes a first position 3061, a second position 3062 that is connected to the first position 3061 and located on a side of the first position 3061 away from the first slot body 307, and a third position 3063 that is connected to the first position 3061 and located on a side of the first position 3061 closer to the first slot body 307. The third position 3063 is connected to the communication opening 309.

[0040] When the first shaft body 304 moves in the slot section, the second shaft body 303 has a reciprocating stage of reciprocating along the second slot body 306 .

[0041] Specifically, the first shaft 304 moves along the first slot section 3071 to the second slot section 3072, at which time the door body 2 rotates in place; as the opening angle of the door body 2 increases, the first shaft 304 moves from the intersection of the first slot section 3071 and the second slot section 3072 along the second slot section 3072 to the intersection of the second slot section 3072 and the third slot section 3073 in the slot section, and the second shaft 303 first moves from the first position 3061 to the second position 3062, then from the second position 3062 to the first position 3061, and finally from the first position 3061 to the third position 3063; at this time, the door body 2 rotates open and translates along a preset direction to avoid interference between the door body 2 and external environmental components;

[0042] In one embodiment of the present application, the first slot section 3071 is an arc slot section with the first position 3061 as the center. In the process of the door body 2 opening from the closed state to the first opening angle, the first shaft body 304 moves in the first slot section 3071 from the end of the first slot section 3071 away from the second slot section 3072 to the junction of the first slot section 3071 and the second slot section 3072, and the second shaft body 303 remains in the first position 3061.

[0043] In an optional embodiment, the third slot segment 3073 is an arc slot segment with the third position 3063 as the center. When the first axis 304 moves from the junction of the second slot segment 3072 and the third slot segment 3073 along the third slot segment 3073 toward the direction away from the second slot segment 3072, the second axis 303 remains in the third position 3063. At this time, the door body 2 rotates in place around the second axis 303 located at the third position 3063 to increase the maximum opening angle of the door body 2.

[0044] Specifically, the second slot body 306 is connected to the first slot body 307 at the third position 3063 .

[0045] Specifically, the groove section is provided with a hovering groove 308. When the first shaft body 304 moves on the groove section to the position of the hovering groove 308, the first shaft body 304 slides into the hovering groove 308. At this time, the door body 2 of the refrigerator is in a hovering state.

[0046] In a specific embodiment, the hovering slot 308 is located at a position of the third slot section 3073 close to the second slot section 3072, and when the first shaft 304 is located in the hovering slot 308, the door body 2 is in a hovering state. At this time, the opening angle of the door body 2 is 90 degrees.

[0047] In some optional embodiments, a guide protrusion is provided at the opening of the hovering slot 308, specifically including a first guide protrusion 310 away from the third slot section 3073 and a second guide protrusion 311 close to the third slot section 3073. When the first shaft 304 enters the hovering slot 308 or when the first shaft 304 leaves the hovering slot 308, it will pass through the guide protrusion. The guide protrusion enables the first shaft 304 to enter the hovering slot 308 more accurately when moving to the hovering slot 308 and stay stably in the hovering slot 308.

[0048] See also Figure 7 When the first shaft 304 moves to the hovering slot 308, the door body 2 and the cabinet 1 form an angle of 90 degrees. Specifically, when the first shaft 304 moves into the hovering slot 308 of the first slot 307, the second shaft 303 is located in the first position 3061 of the second slot 306. At this time, the door body 2 is opened at an angle of 90 degrees. Since the first shaft 304 is located in the hovering slot 308, when the door body 2 is opened at an angle of 90 degrees, the overall stability of the refrigerator is enhanced, which helps prevent the door body 2 from accidentally closing or shaking when it is opened at 90 degrees, thereby improving the safety of use. The present application makes the first shaft 304 located in the hovering slot 308 when the door body 2 and the cabinet 1 form an angle of 90 degrees because when the door body 2 is opened at an angle of 90 degrees and is in a vertical state with the cabinet 1, the door body 2 does not occupy too much external space, thereby avoiding interference between the door body 2 and the external environment.

[0049] In one embodiment of the present application, the first shaft 304 and the second shaft 303 have the same length, and the first slot 307 and the second slot 306 have the same depth. The consistency of the lengths of the first shaft 304 and the second shaft 303, and the depths of the first slot 307 and the second slot 306, ensures better compatibility between the shaft 301 and the slot 305 when used together, allowing for smoother interaction and achieving smooth opening and closing of the door 2.

[0050] The first shaft 304 and the second shaft 303 have different shaft diameters. Specifically, the shaft diameter of the first shaft 304 is smaller than the shaft diameter of the second shaft 303. When the refrigerator door 2 is rotated to open or close, the second shaft 303 bears more weight and stress. The larger shaft diameter helps to improve its durability and reliability.

[0051] The first slot body 307 corresponding to the first shaft body 304 has a first slot width, and the second slot body 306 corresponding to the second shaft body 303 has a second slot width. The first slot width is different from the second slot width. The first slot width of the first slot body 307 is smaller than the second slot width of the second slot body 306. The first slot width is the width perpendicular to the length extension direction of the first slot body 307, and the second slot width is the width perpendicular to the length extension direction of the second slot body 306. When installing, first place the first shaft body 304 at any position in the second slot body 306. Since the second slot width of the second slot body 306 is larger than the first slot width of the first slot body 307, The first shaft 304 is wider, and it is easier for the first shaft 304 to enter the second groove body 306. Based on the connection setting of the first groove body 307 and the second groove body 306, the first shaft 304 slides toward the first groove body 307 in the second groove body 306, and at the same time, drives the second shaft 303 to enter the second groove body 306, and finally realizes the completion state of the corresponding installation of the first shaft 304 and the first groove body 307, and the corresponding installation of the second shaft 303 and the second groove body 306; compared with the previous double-grooves non-connected setting, the connection setting of the first groove body 307 and the second groove body 306 of the present application realizes fast and accurate installation with less manpower during the actual installation process.

[0052] The refrigerator in the present application includes a cabinet, a door, and a hinge assembly connecting the door and the cabinet. The hinge assembly includes a groove provided on one of the cabinet and the door, and an axis provided on the other. The groove includes a first groove and a second groove. The axis includes a first axis that cooperates with the first groove and a second axis that cooperates with the second groove. The first groove and the second groove have a first angle, and the first groove and the second groove are connected. The first groove and the second groove are connected to each other, thereby reducing interference between the axis and the outer periphery of the groove during installation and reducing friction between the axis and the groove during use, so that the hinge assembly rotates more flexibly.

[0053] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
