It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the description of the embodiments of the present application, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, are not to be construed as limiting the embodiments of the present application.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present disclosure, and fig. 2 is an exploded view of a hinge and a door of the refrigerator shown in fig. 1. The embodiment of the present application provides a refrigerator, which may include a cabinet 10, a door 20, and a hinge 30. The cabinet 10 is provided with a storage compartment such as a freezing compartment, a refrigerating compartment, or a wide temperature-variable compartment. Of course, in some alternative embodiments, the storage compartment may also be a thawing compartment or a sterilization compartment with a thawing function, which is not limited in the examples of the present application. The door 20 is used to open or close the storage compartment of the cabinet 10. Wherein door 20 may be hingedly coupled to cabinet 10 via hinge 30. Specifically, hinges 30 may be provided at the upper and lower portions of the cabinet 10, and the door 20 may be smoothly rotated by the hinges 30 at the upper portion of the cabinet 10 and the hinges at the lower portion of the cabinet 10 cooperating with the door 20.

Wherein, the front end of storing room is formed with the opening or gets and put the mouth to place food to storing indoor or by the indoor food of taking out of storing room. Correspondingly, the box body comprises an opening end surface 11 forming an opening of the storage compartment.

In some embodiments, door 20 is provided with at least two sliding slots. The hinge 30 is connected to the cabinet 10, and the hinge 30 has at least two shafts. Each shaft body corresponds to one sliding groove, each shaft body is inserted into the corresponding sliding groove, and the shaft bodies can move in the corresponding sliding grooves to enable the box door 20 to be rotatably connected with the box body 10. The refrigerator also includes a drive mechanism 40. The driving mechanism 40 includes a first guide 41 provided to the hinge 30 and a second guide 42 provided to the door 20. When the door 20 rotates to a predetermined angle relative to the cabinet 10, the second guide 42 can move along the surface of the first guide 41 under the driving of the gravity of the door 20 to rotate the door 20 to open or close the cabinet 10.

In the refrigerator in the embodiment of the present application, on one hand, the track of the door 20 in the rotation process can be adjusted through the matching of the plurality of shafts and the plurality of sliding grooves between the door 20 and the refrigerator body 10. On the other hand, through the cooperation of the first guide 41 and the second guide 42, the door 20 may be automatically rotated to be opened or closed when the door 20 is rotated to a preset angle. Further, it is possible to prevent the door 20 from stopping moving after the user turns to a predetermined angle and releases his/her hand, and the user is still required to perform a secondary operation to open and close the door.

Referring to fig. 3 and 4, fig. 3 is a schematic structural view of a door of the refrigerator shown in fig. 2, and fig. 4 is a schematic structural view of a hinge of the refrigerator shown in fig. 2. Illustratively, the first guide 41 may include a first top surface 411 and at least one guide slope 412. The first top surface 411 is disposed perpendicular to the direction of gravity. The first top surface 411 is connected to a guide slope 412 at least at one end in the circumferential direction of the shaft body. The guiding inclined plane 412 is inclined downwards along the gravity direction in a direction away from the first top surface 411, so that the second guiding element 42 can be driven by the gravity of the door 20 to move along the guiding inclined plane 412 to rotate the door 20.

Specifically, one end of the first top surface 411 in the circumferential direction of the shaft body may be connected with one guide slope 412, or only one guide slope 412 may be connected with the first top surface 411.

At this time, the predetermined angle may be that the door 20 rotates until the second guiding element 42 abuts against the guiding inclined surface 412, so that the door 20 may form a wedge transmission structure with the guiding inclined surface 412 and the second guiding element 42 to achieve an automatic opening and closing motion or an automatic door closing motion.

Alternatively, one guiding inclined surface 412 may be connected to each end of the first top surface 411 along the circumferential direction of the shaft body, or two guiding inclined surfaces 412 may be connected to the first top surface 411.

At this time, the preset angle may include a fourth preset angle and a fifth preset angle. The fourth preset angle is that the door 20 rotates until the second guide 42 abuts against one of the guide slopes 412, so that the door 20 can form a wedge transmission structure through the guide slope 412 and the second guide 42 to realize an automatic door opening action. The fifth preset angle is that the door 20 rotates until the second guide 42 abuts against one of the guide slopes 412, so that the door 20 can form a wedge transmission structure with the second guide 42 through the guide slope 412 to realize an automatic closing action.

Specifically, the fourth preset angle may be 48 °, 55 °, 63.2 °, 70 °, or the like, between the box door 20 and the box 10, which is not limited in this embodiment.

Specifically, the fifth preset angle may be 8 °, 17.5 °, 32 °, 41.7 °, or the like, between the box door 20 and the box 10, which is not limited in this embodiment.

In some embodiments, the second guide 42 may include a second top surface 421 and at least one sliding slope 422. The second top surface 421 is parallel to the first top surface 411. At least one end of the second top surface 421 along the circumferential direction of the shaft body is connected with a sliding inclined surface 422. The guiding inclined planes 412 are inclined upwards along the gravity direction in the direction away from the second top surface 421, and each sliding inclined plane 422 is parallel to one guiding inclined plane 412, so that the sliding inclined planes 422 can slide along the mutually parallel guiding inclined planes 412 under the driving of the gravity of the door to drive the door to rotate.

It is understood that, due to the heavy weight of door 20, surface contact between first guide 41 and second guide 42 may be formed by cooperation of guide slope 412 and slide slope 422. Furthermore, compared with the line contact between the first guide 41 and the second guide 42, the first guide 41 and the second guide 42 can be stressed more uniformly and are not easy to damage. And simultaneously, the stability and reliability of the box door 20 during rotation are also ensured.

In some embodiments, the second guide 42 comprises rolling elements such as balls or needles. The rolling member can be driven by the gravity of the door 20 to roll along the guiding inclined plane 412 to rotate the door 20. Further, rolling friction is formed between the first guide 41 and the second guide 42, so that the movement of the rolling member can be smoother during the rotation of the door 20.

In some embodiments, the first guide 41 may be a self-lubricating and wear-resistant material. For example, the first guide 41 may be ductile iron, polyoxymethylene (pom), or the like. Furthermore, during the relative movement of the first guide 41 and the second guide 42, the degree of wear of the first guide 41 and the second guide 42 may be reduced, and the relative movement of the first guide 41 and the second guide 42 may be smoother.

In some embodiments, the second guide 42 may be a self-lubricating and wear-resistant material. For example, the second guide 42 may be ductile iron, polyoxymethylene (pom), or the like. Furthermore, during the relative movement of the first guide 41 and the second guide 42, the degree of wear of the first guide 41 and the second guide 42 may be reduced, and the relative movement of the first guide 41 and the second guide 42 may be smoother.

The above are some illustrations of the drive mechanism 40 of the embodiments of the present application. The following description will proceed with an example of the multi-axis hinge structure according to the embodiment of the present application, with reference to the structures of the cabinet 10 and the door 20.

Referring to fig. 5, fig. 5 is a sectional view of the refrigerator shown in fig. 1. The case 10 includes first and second oppositely disposed sidewalls 12 and 13 (i.e., right and left sidewalls of the case 10). The hinge 30 is disposed on the case 10 adjacent to the first sidewall 12. Alternatively, the hinge 30 is provided on the casing 10 near the second sidewall 13. Of course, for a double door refrigerator, the hinge 30 is provided adjacent to both the first side wall 12 and the second side wall 13.

The door 20 includes a door rear wall surface 211, a door front wall surface 212, and a door side wall surface 213 adjacent to the hinge 30, it being understood that the door rear wall surface 211 faces the open end surface 11 of the cabinet 10 when the door 20 is in the closed state. The door rear wall surface 211 is disposed opposite to the door front wall surface 212, and the door side wall surface 213 is connected to the door rear wall surface 211 and the door front wall surface 212. It is understood that when the hinge 30 is located at the right side of the box 10, the right side surface of the door 20 is the door side wall surface 213; when the hinge 30 is located at the left side of the casing 10, the left side surface of the door 20 is a door side wall surface 213. The intersection of the door front wall surface 212 and the door side wall surface 213 of door 20 forms a first side edge 214, or the intersection of the door front wall surface 212 and the door side wall surface 213 forms a corner portion of door 20. It should be noted that when the door front wall 212 and the door side wall 213 are both flat surfaces, the intersection line of the two flat surfaces is the theoretical first side edge 214, and when the door front wall 212 and the door side wall 213 are processed and set specifically, based on the fact that the intersection point of the door front wall 212 and the door side wall 213 passes through a rounded corner, a curved surface is formed at this time, and a vertical line extending along the length direction of the door 20 and located in the middle of the curved surface on the curved surface can represent the first side edge 214.

It should be noted that, in the related art, when the box door rotates, the corner portion (or the first lateral edge) of the box door may exceed the side wall of the box body by an excessive distance, and at this time, if the box body is closer to the side wall of the wall or the cabinet, the corner portion of the box door may touch the wall or the cabinet on the side of the refrigerator, which directly affects the use of the user.

Based on this, please refer to fig. 6 to 8, wherein fig. 6 is a schematic view of a sliding groove of the door shown in fig. 2, fig. 7 is a schematic view of a state that the door of the refrigerator shown in fig. 2 is closed, and fig. 8 is a partially enlarged view of a portion a of the structure shown in fig. 7. The at least two shafts of the hinge 30 include a first shaft 31 and a second shaft 32, and the first shaft 31 is located between the casing 10 and the second shaft 32. Specifically, the first shaft 31 is located between the opening end face 11 of the refrigerator and the second shaft 32, or the first shaft 31 is closer to the opening end face 11 of the refrigerator than the second shaft 32. The at least two slide slots of door 20 include a first slide slot 22 engaged with first shaft 31 and a second slide slot 23 engaged with second shaft 32. It can be understood that the first shaft body 31 is inserted into the first sliding groove 22, and the second shaft body 32 is inserted into the second sliding groove 23. During the process of rotating the door 20 from the closed state to the first preset angle a, the door 20 can rotate with the second shaft 32 as the rotation axis, and the first shaft 31 can slide relative to the first sliding chute 22.

Referring to fig. 9 and 10, fig. 9 is a schematic view illustrating a state where the door of the refrigerator shown in fig. 5 is opened to a first preset angle, and fig. 10 is a schematic view illustrating a state where the door of the refrigerator shown in fig. 5 is opened to a second preset angle. During the process of opening the door 20 from the first preset angle a to the second preset angle b, the door 20 can rotate with the first shaft 31 as a rotation axis, and the second shaft 32 can slide relative to the second chute 23. It will be appreciated that the first preset angle a is greater than the second preset angle b. Through the cooperation of the first shaft 31 and the first sliding groove 22 and the cooperation of the second shaft 32 and the second sliding groove 23, after the door 20 rotates to a certain angle in a fixed axis manner, the other shaft can be replaced to perform fixed axis rotation movement, that is, the door 20 performs two stages of variable diameter movement in the rotation process, and because the first shaft 31 is located between the box body 10 and the second shaft 32, in the process that the door 20 rotates from the closed state to the second preset angle b, the rotation radius of the corner of the door 20 rotating around the second shaft 32 is smaller than that of the corner of the door 20 rotating around the first shaft 31, so that the rotation center of the door 20 starts to be adjusted when the corner of the door 20 exceeds the side wall of the box body 10 by a small distance (at this time, the door 20 rotates around the first shaft 31 as the rotation axis), so as to avoid the cabinet or the wall at the side of the refrigerator, and enable the door 20 to move smoothly when the door 20 is opened.

It is understood that the upper and lower ends of the refrigerator are provided with hinges 30, and the upper and lower ends of the door 20 are provided with first and second sliding

grooves

22 and 23 corresponding to the positions of the hinges 30. And the first sliding grooves 22 at the upper and lower ends of the door 20 correspond to each other in vertical position, and the second sliding grooves 23 at the upper and lower ends of the door 20 correspond to each other in vertical position, so that the movement of the upper and lower ends of the door 20 is kept consistent, and the door 20 is opened or closed more smoothly.

It will also be understood that the hinge 30 comprises a connecting plate 33, the connecting plate 33 being fixed to the cabinet 10 of the refrigerator, such as by means of a screw connection, the connecting plate 33 being fixable to the cabinet 10 of the refrigerator. The first shaft body 31 and the second shaft body 32 are provided to the connecting plate 33. The first shaft 31 and the second shaft 32 are integrally formed with the connecting plate 33. The first shaft 31 and the second shaft 32 may be formed as a separate body from the connecting plate 33 and then assembled to the connecting plate 33.

It can also be understood that the first shaft body 31 and the second shaft body 32 are rotatably connected to the connecting plate 33 in order that the first shaft body 31 and the second shaft body 32 rotate or slide more smoothly in the corresponding sliding grooves.

In order to more clearly illustrate the matching connection relationship between the first shaft 31 and the first sliding chute 22, and the matching connection relationship between the second shaft 32 and the second sliding chute 23, the detailed structure of the first shaft 31, the first sliding chute 22, the second shaft 32 and the second sliding chute 23 will be described in detail below with reference to the drawings.

Referring to fig. 4 to 7, the first sliding slot 22 is communicated with the second sliding slot 23, the depth of the first sliding slot 22 is greater than that of the second sliding slot 23, the first shaft 31 extends to the first sliding slot 22, and the second shaft 32 extends to the second sliding slot 23. In this manner, the positions of the first and

second chutes

22 and 23 can be made relatively more compact.

The first sliding chute 22 includes a first positioning section 221 and a first track section 222 which are communicated with each other, the first track section 222 includes a first chute wall which is in contact with the first shaft 31, and during the process that the door 20 rotates from the closed state to the first preset angle a, the door 20 can rotate with the second shaft 32 as a rotation axis, and at this time, the first shaft 31 can slide relative to the first track section 222 and slide to the first positioning section 221. During the process of opening the door 20 from the first preset angle a to the second preset angle b, the first shaft 31 can rotate relative to the first positioning segment 221, that is, at this time, the door 20 can rotate with the first shaft 31 as a rotation axis, and the second shaft 32 can slide relative to the second chute 23.

It is understood that the second sliding chute 23 comprises a second positioning segment 231 and a second track segment 232 which are communicated with each other, and the second track segment 232 comprises a second chute wall which is contacted with the second shaft body 32. When the door 20 is in the closed state, the second shaft 32 is located in the second positioning segment 231, and in the process that the door 20 rotates from the closed state to the first preset angle a, the second shaft 32 can rotate relative to the second positioning segment 231, and at this time, the first shaft 31 can slide relative to the first track segment 222 and slide to the first positioning segment 221. During the process of opening the door 20 from the first preset angle a to the second preset angle b, the first shaft 31 can rotate relative to the first positioning segment 221, that is, at this time, the door 20 can rotate with the first shaft 31 as a rotation axis, and the second shaft 32 can slide relative to the second track segment 232.

In this way, when the door 20 rotates from the closed state to the first preset angle a, the second shaft 32 relatively rotates in the second positioning segment 231, the door 20 can rotate with the second shaft 32 as a rotation axis, the first shaft 31 slides to the first positioning segment 221 relative to the first track segment 222, at this time, the door 20 continues to rotate, and when the door 20 opens from the first preset angle a to the second preset angle b, the first shaft 31 relatively rotates in the first positioning segment 221, the door 20 can rotate with the first shaft 31 as a rotation axis, and the second shaft 32 slides relative to the second track segment 232. That is, when the door 20 rotates from the closed state to the first preset angle a, the door 20 rotates with the second shaft 32 as the rotation axis, and when the door 20 rotates from the first preset angle a to the second preset angle b, the door 20 rotates with the first shaft 31 as the rotation axis, and the door 20 performs two-stage diameter-variable movement during the rotation process, so that the rotation center of the door 20 starts to be adjusted when the corner of the door 20 exceeds the side wall surface of the box 10 by a small distance, so as to avoid the cabinet or the wall on the side of the refrigerator, and make the door 20 move smoothly when being opened.

The first track segment 222 and the second track segment 232 are arc-shaped grooves, and the arc-shaped first track segment 222 and the arc-shaped second track segment 232 play a role in guiding. The first positioning segment 221 is located at the center of the second track segment 232, and the second positioning segment 231 is located at the center of the first track segment 222.

It should be understood that, referring to fig. 8, fig. 8 is an enlarged view of a point a in fig. 5. When the door 20 is rotated from the closed state to the first predetermined angle a, that is, when the door 20 is rotated around the second shaft 32, it is required to ensure that the first side edge 214 of the door 20 (or the corner portion of the door 20) does not collide with the wall or the cabinet wall. Based on this, the distance between the groove center of the second positioning segment 231 and the door front wall 212 is denoted as L ₁ The distance between the groove center of the second positioning segment 231 and the door side wall surface 213 is denoted as L ₂ The distance between the side wall 213 of the door and the wall or the cabinet wall is denoted as L ₃ It is also understood that the distance between the axis of the second shaft 32 and the door front wall 212 when the door 20 is in the closed state is denoted as L ₁ The distance between the axis of the second shaft 32 and the door side wall 213 is L ₂ Wherein, in the step (A),

thus, when the door 20 rotates around the second shaft 32, the arc-shaped path of the first side edge 214 does not interfere with the wall or the cabinet wall.

For example, in the case of a built-in refrigerator, the distance between the side plate of the built-in cabinet and the side wall of the refrigerator is small, and is generally 2 mm to 4 mm. Based on this, in order to improve the adaptability without greatly modifying the structure of the door 20 of the existing refrigerator, the distance L between the groove center of the second positioning section 231 and the front wall surface 212 of the door may be set ₁ A distance L between the groove center of the second positioning segment 231 and the side wall surface 213 of the door, which is set between 8.5 mm and 10.5 mm ₂ Set between 14 mm and 17 mm. Or, the distance L between the axis of the second shaft 32 and the door front wall 212 when the door 20 is in the closed state ₁ A distance L between the axis of the second shaft 32 and the side wall 213 of the door is set between 8.5 mm and 10.5 mm ₂ Set between 14 mm and 17 mm. In this way, when the door 20 is rotated around the second shaft 32 without greatly modifying the structure of the door 20 of the existing refrigerator, such as the thickness of the door 20,the arcuate path followed by the first side edge 214 does not interfere with a wall or cabinet wall.

For example, the distance L between the slot center of the second positioning segment 231 and the door front wall 212 may be set to be shorter ₁ The distance L between the groove center of the second positioning segment 231 and the side wall surface 213 of the door is set to 9 mm ₂ With a 16 mm setting, since a rounded corner with a radius of 1 mm is generally formed at first side edge 214 (at the corner of door 20), first side edge 214 may not exceed 2 mm beyond the side wall of cabinet 10 during rotation of door 20.

It can be understood that, after the door 20 moves to the first predetermined angle a by using the second shaft 32 as a rotating shaft, the door 20 moves to the second predetermined angle b by using the first shaft 31 as a rotating shaft, so as to implement two-stage diameter-variable movement of the door 20. The center distance between the first shaft 31 and the second shaft 32 is set between 9.5 mm and 12.5 mm, and when the door 20 is in the closed state, the first shaft 31 is farther away from the door sidewall surface 213 than the second shaft 32. Thus, when the door 20 is converted to move with the first shaft 31 as a rotating shaft, the installation position of the first shaft 31 can prevent the arc-shaped track of the first side edge 214 from interfering with the wall or the cabinet wall during the rotation of the door 20. And when the door 20 moves to the second preset angle b, the door 20 does not obstruct the drawer in the storage compartment from being pulled out.

As shown in fig. 5, an angle d between an extension line of a connecting line between the center of the first shaft 31 and the center of the second shaft 32 and an extension plane of the door side wall surface 213 is in a range of 15 degrees to 25 degrees, so that the door 20 can perform two-stage diameter-changing movement more smoothly.

For ease of understanding, the following description will be made in conjunction with a specific rotational angle of door 20.

For example, the first preset angle a may be 45 degrees, and the second preset angle b may be 90 degrees, but in other embodiments, the first preset angle a may be other angles such as 30 degrees or 35 degrees, and the second preset angle b may be other angles such as 80 degrees or 85 degrees, and the embodiments of the present application are not limited herein.

In the embodiment of the present application, the first predetermined angle a is 45 degrees, and the second predetermined angle b is 90 degrees. When the door 20 is opened to an angle of 45 degrees from the closed state, the second shaft 32 rotates relatively in the second positioning segment 231, the door 20 can rotate with the second shaft 32 as a rotation axis, the first shaft 31 slides relative to the first track segment 222 to the first positioning segment 221, at this time, the door 20 continues to rotate, and during the door 20 is opened to an angle of 90 degrees from the angle of 45 degrees, the first shaft 31 rotates relatively in the first positioning segment 221, at this time, the door 20 can rotate with the first shaft 31 as a rotation axis, and the second shaft 32 slides relative to the second track segment 232.

In some embodiments, the door 20 may be opened to a position greater than a second predetermined angle b (such as 90 degrees), and the refrigerator may be placed in a position with a larger accommodating space, and it can be understood that when the space is larger, the problem that the door 20 collides with the surrounding wall surface when the door 20 is rotated to a position greater than 90 degrees does not need to be considered.

Referring to fig. 11, fig. 11 is a schematic diagram illustrating a state in which a door of the refrigerator shown in fig. 5 is opened to a third preset angle. The door 20 may be opened to a third preset angle c that is greater than the second preset angle b, such as the third preset angle c may be 120 degrees. The second sliding chute 23 may further include a limiting section 233 communicated with the second track section 232, the limiting section 233 is located at one end of the second track section 232 far from the second positioning section 231, and in the process that the door 20 is opened from the second preset angle b to the third preset angle c, the door 20 may rotate with the first shaft 31 as a rotation axis, and the second shaft 32 may slide against the wall of the limiting section 233 relative to the second track section 232. Thus, the door 20 can be restricted from rotating around the first shaft 31 by the limiting action of the limiting section 233.

It is also understood that the first sliding groove 22 cooperating with the first shaft 31 and the second sliding groove 23 cooperating with the second shaft 32 may be directly formed on the door 20. In some embodiments, the first sliding groove 22 and the second sliding groove 23 may be formed on the sliding groove member, and then the sliding groove member is installed on the position of the door 20 corresponding to the hinge 30, so as to form the first sliding groove 22 and the second sliding groove 23 on the position of the door 20 corresponding to the hinge 30.

In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.
