Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, in particular to a refrigerator. Background Art

[0002] Built-in refrigerators are placed inside a cabinet. Due to cabinet space limitations, to maximize the refrigerator's utilization of cabinet space, it is required that the door's corners protrude minimally or not at all from the cabinet during opening. To address this, hinge assemblies with two shafts and two slots are often used. This allows the door to move away from the cabinet during opening, limiting the amount of protrusion from the door's corners, thereby maximizing cabinet space utilization.

[0003] After the refrigerator door is opened, its center of gravity shifts. On the one hand, the center of gravity shift will cause the door to close automatically, making it impossible for the door to remain in the open state, causing inconvenience to the user in taking and placing items; on the other hand, the double groove setting in the hinge assembly with two axes and two grooves often has trajectory change points. The center of gravity shift will cause the axis and the groove to easily slip relative to each other at the change point, making it impossible for the door to stably remain in its open position. Summary of the Invention

[0004] The present application provides a refrigerator, when the door body is opened to G4=90°, the first axis moves to the inflection point position relative to the guide part, and the second axis is located at the end of the guide part close to the side wall of the first body. The movement stability of the first axis relative to the guide part and the second axis relative to the guide part is high. When the door body is opened to 90°, the rotation relative to the box body is more stable, and the door body can also be maintained at 90°.

[0005] In a first aspect, a refrigerator is provided, comprising:

[0006] The box body defines a plurality of accommodating cavities with access openings; the box body has a first side wall and a second side wall that are oppositely arranged;

[0007] The door body is connected to the box body to close or open the accommodating cavity; the door body has:

[0008] a door front wall, which is away from the box body when the door body is closed;

[0009] a door side wall connected to the door front wall and located on a side of the door body away from the second body side wall when the door body is in a closed state;

[0010] A hinge assembly connects the door body to the box body so that the door body can be flipped relative to the box body; the hinge assembly includes:

[0011] A first hinge member is provided on the box body and is close to the side wall of the first body; the first hinge member includes:

[0012] a hinge plate connected to the box body;

[0013] a first shaft and a guide portion, which are provided on the hinge plate;

[0014] A second hinge member is provided on the door body; the second hinge member comprises:

[0015] a second shaft, which cooperates with the guide portion;

[0016] a guide portion, which cooperates with the first shaft;

[0017] The guide portion extends from an end thereof away from the door side wall to a side close to the door side wall and away from the door front wall, and then extends to a side close to the door side wall and the door front wall;

[0018] When the door body is opened to G4=90°, the first shaft moves relative to the guide portion to a position where the distance between the first shaft and the door front wall is the largest, and the second shaft is located at the end of the guide portion close to the first body side wall.

[0019] In the above technical solution, when the door body is opened to G4=90°, the first axis moves to the inflection point relative to the guide part, and the second axis is located at the end of the guide part close to the side wall of the first body. The movement stability of the first axis relative to the guide part and the second axis relative to the guide part is high. When the door body is opened to 90°, the rotation relative to the box body is more stable, and the door body can also be maintained at 90°.

[0020] In some embodiments, the guide portion extends from its end away from the first body side wall to a side close to the first body side wall and away from the plane where the access port is located, and then extends to a side close to the first body side wall and the plane where the access port is located.

[0021] In the above technical solution, the extension trend of the guide portion is limited and divided into two sections. The extension trend of the guide portion is simple, thereby improving the movement smoothness of the second axis relative to the guide portion.

[0022] In some embodiments, during the process of the door body opening from G4=90° to G5, the second axis moves relative to the guide portion toward the side away from the first body side wall and the plane where the take-and-put port is located, and the first axis moves relative to the guide portion toward the side close to the door side wall and the door front wall; wherein, G4<G5.

[0023] In the above technical solution, the movement direction of the second axis relative to the guide part and the movement direction of the second axis relative to the guide part are defined in the process of the door body opening from G4=90° to G5, so as to guide the movement of the door body along the width direction and the front and back direction of the box body, so as to reduce the restriction of the cabinet on the door body and increase the maximum angle that the door body can open in the cabinet.

[0024] In some embodiments, when the door body is opened from G3 to G4=90°, the second axis moves relative to the guide portion toward the side close to the first body side wall and the plane where the pick-up and release port is located, and the first axis moves relative to the guide portion toward the side close to the door side wall and away from the door front wall; wherein, G3<G4.

[0025] In the above technical solution, the movement direction of the second axis relative to the guide part and the movement direction of the second axis relative to the guide part are defined in the process of the door body opening from G3 to G4 = 90°, so as to guide the movement of the door body in the width direction and front-to-back direction of the box body, so as to effectively reduce the obstruction of the door body to the take-and-put port, increase the utilization rate of the drawer located in the accommodating cavity to the width direction space of the accommodating cavity, and do not affect the withdrawal of the drawer from the accommodating cavity.

[0026] In some embodiments, the first axis is located on a side of the guide portion away from the first body side wall, and the second axis is located on a side of the guide portion close to the door front wall.

[0027] In the above technical solution, the relative positions of the first shaft and the guide portion and the relative positions of the second shaft and the guide portion are defined, so that the structure of the hinge assembly is more compact to ensure its strength.

[0028] In some embodiments, the motion trajectory of the central axis of the first shaft relative to the guide portion is recorded as a guide trajectory line F, and the guide trajectory line F extends from an end thereof away from the door side wall to a side close to the door side wall and away from the door front wall, and then extends to a side close to the door side wall and the door front wall;

[0029] The point where the guide trajectory line F has the largest distance from the door front wall is recorded as the third guide point H;

[0030] In a plane projection parallel to the top wall of the box, along a direction perpendicular to the door side wall, a distance between the center axis of the second axis and the third guide point H is recorded as |PH|2; wherein 0mm≤|PH|2≤5mm.

[0031] In the above technical solution, when 5mm<|PH|2, |PH|2 is too large, and the distance between the second axis and the third guide point H on the guide trajectory line that is the closest to the door front wall in the direction perpendicular to the door side wall is too large; during the movement of the door body relative to the box body, when the first center axis Q moves to the third guide point H, the distance between the second center axis and the first center axis in the direction perpendicular to the door side wall is too large, and the straight line where the first center axis and the second center axis are located is too inclined at an angle relative to the plane where the pick-up and release port is located. At this time, the stability of the door body's movement relative to the box body is poor.

[0032] In the present application, with the setting of 0mm≤|PH|2≤5mm, the second axis is close to the third guide point H on the guide trajectory line which is the longest distance from the door front wall in the direction perpendicular to the door side wall; when the door body moves relative to the box body, the first center axis Q moves to the third guide point H, and the second center axis is close to the first center axis in the direction perpendicular to the door side wall, thereby effectively ensuring the stability of the door body movement relative to the box body.

[0033] In some embodiments, the point where the guide trajectory line F is away from the door side wall and has the smallest distance from the door front wall is recorded as the first guide point K;

[0034] In a plane projection parallel to the top wall of the box, along a direction perpendicular to the front wall of the door, the distance between the center axis of the second axis and the first guide point K is recorded as |PK|1; wherein 0mm≤|PK|1≤3mm.

[0035] In the above technical solution, when 3mm<|PK|1, |PK|1 is too large, and the distance between the second center axis P and the first guide point K on the guide trajectory line that is the largest distance from the door side wall is too large in the direction perpendicular to the front wall of the door; during the movement of the door body relative to the box body, when the first center axis Q is located at the first guide point K, the distance between the second center axis and the first center axis in the direction perpendicular to the front wall of the door is too large, and the straight line where the first center axis and the second center axis are located is too inclined at an angle relative to the plane where the pick-up and release port is located. At this time, the stability of the door body relative to the box body is poor.

[0036] In the present application, with the setting of 0mm≤|PK|1≤3mm, the second axis is close to the first guide point K on the guide trajectory line which is the longest distance from the door side wall in the direction perpendicular to the front wall of the door; during the movement of the door body relative to the box body, when the door body is closed, the first center axis Q is located at the first guide point K, and in the direction perpendicular to the door side wall, the second center axis P is close to the first center axis, thereby effectively ensuring the stability of the movement of the door body relative to the box body.

[0037] In some embodiments, the motion trajectory of the central axis of the second shaft relative to the guide portion is recorded as a guide trajectory line S, and the guide trajectory line S extends from its end away from the first body side wall to a side close to the first body side wall and away from the plane where the access port is located, and then extends to a side close to the first body side wall and the plane where the access port is located;

[0038] The point where the distance between the guide track line S and the plane where the pick-up and release port is located is the largest is recorded as the first guide point P1;

[0039] Among them, 0mm≤|QP1|1≤4mm.

[0040] In the above technical solution, when 4mm<|QP1|1, when the second axis 6 moves to the point where the distance between the guide part 7 and the plane where the pick-up and release port is located is the largest, the distance between the second axis 6 and the first axis 5 in the direction perpendicular to the plane where the pick-up and release port is located is too large, resulting in the door body 3 relative to the box body 1. The displacement in the direction perpendicular to the plane where the pick-up and release port is too large, resulting in an imbalance in the movement of the door body 3 relative to the box body 1 in the width direction and the movement in the front-to-back direction, and cannot effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0041] In the present application, the setting of 0mm≤|QP1|1≤4mm enables the second axis 6 to move to the point where the distance between the guide portion 7 and the plane where the pick-up and release port is located is the largest. In the direction perpendicular to the plane where the pick-up and release port is located, the second axis 6 is close to the first axis 5, effectively controlling the displacement of the door body 3 relative to the box body 1 in the direction perpendicular to the plane where the pick-up and release port is located, so as to control the movement of the door body 3 relative to the box body 1 in the width direction and the front-to-back direction, so as to reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3, so that the door body 3 can be opened to a larger angle.

[0042] In some embodiments, the guide trajectory line S is an arc; the radius of the arc-shaped guide trajectory line S is recorded as the guide radius R; 8mm≤R≤12mm.

[0043] In the above technical solution, when R is less than 8 mm, the guide radius R is too small and the curvature of the guide trajectory S is too large, resulting in a too rapid change in the movement speed of the second shaft 6 relative to the guide portion 7 .

[0044] When 12mm<R, the guide radius R is too large and the curvature of the guide trajectory line S is too small, resulting in too small a change in the movement speed of the second shaft 6 relative to the guide part 7, and the length of the guide trajectory line is too long. The guide part 7 occupies a large space of the hinge plate 4, resulting in a decrease in the strength of the hinge plate 4 and also a decrease in the strength of the guide part 7, thereby reducing the service life of the hinge assembly.

[0045] The above arrangement of 8mm≤R≤12mm, on the one hand, stabilizes the movement of the second shaft 6 relative to the guide portion 7, thereby improving the stability of the movement of the door body 3 relative to the housing 1. On the other hand, the area occupied by the guide portion 7 on the hinge plate 4 is limited, thereby ensuring the strength of the hinge plate 4 and the guide portion 7, effectively ensuring the service life of the hinge assembly.

DETAILED DESCRIPTION

[0084] The present invention is described in detail below by way of exemplary embodiments, but it should be understood that elements, structures, and features of one embodiment may be beneficially combined in other embodiments without further description.

[0085] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0086] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0087] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0088] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0089] The embodiment of the present application provides a refrigerator 100, referring to Figures 1-20 Refrigerator 100 includes a housing 1 having a storage cavity, a door 3 connected to housing 1 to open and close the storage cavity, and a refrigeration device that supplies cold air to the storage cavity. Housing 1 includes an inner container defining the storage cavity, an outer shell connected to the outer side of the inner container to form the appearance of refrigerator 100, and an insulating layer provided between the inner container and the outer shell to insulate the storage cavity.

[0090] Among them, see Figure 1 The direction from the bottom wall to the top wall of the box body 1 is the height direction. The direction extending from the intersection line of the top wall and the rear wall of the box body 1 is the width direction. The direction perpendicular to both the height direction and the width direction is the front-back direction.

[0091] In some embodiments of the present application, the box body 1 defines a plurality of accommodating cavities. A take-in / take-out opening for taking and placing items is formed at the front end of the accommodating cavity, through which a user can place food into the accommodating cavity or take food out of the accommodating cavity. A rotatable door body 3 is provided on the box body 1 to open or close the take-in / take-out opening of the accommodating cavity. For example, the door body 3 is rotatably connected to the box body 1 by a hinge assembly located at the top and a hinge assembly located at the bottom. In the front-to-back direction, the take-in / take-out opening of the box body 1 is located on the front side relative to the wall surface of the box body 1 opposite to the take-in / take-out opening (the rear wall of the box body 1).

[0092] In some embodiments of the present application, the multiple accommodating chambers may include a refrigerating chamber and a freezing chamber to form accommodating chambers with different temperatures for storing different items.

[0093] In some embodiments of the present application, the box body 1 includes a first side wall (i.e., one of the left and right sides of the box body 1) and a second side wall (i.e., the other of the left and right sides of the box body 1) disposed opposite each other along its width. A hinge assembly is disposed on the box body 1 near the first side wall to connect a door body 3 near the first side wall to the box body 1, allowing the door body 3 to rotate relative to the box body 1 to open or close the access opening.

[0094] The door body 3 includes a front wall 31 that is spaced away from the housing 1 when the door body 3 is closed, a rear wall 32 that is opposite the front wall 31, and a side wall 33 that is adjacent to the first side wall and connected to the front wall 31. For example, when the hinge assembly is located on the right side of the housing 1, the right side wall of the door body 3 serves as the side wall 33. When the hinge assembly is located on the left side of the housing 1, the left side wall of the door body 3 serves as the side wall 33. It should be noted that the front wall 31 is the surface of the door body 3 that is closest to the front when the door body 3 is closed. If the door body 3 includes a glass panel located at its front side when the door body 3 is closed, the front wall 31 is the surface of the glass panel that is closest to the front. The rear wall 32 is the surface of the door body 3 that is closest to the rear when the door body 3 is closed. When the door body 3 is closed, the distance between the front wall 31 and the plane of the access opening is the greatest, and the distance between the rear wall 32 and the plane of the access opening is the smallest.

[0095] In some embodiments of the present application, the door side wall 33 is connected to the door front wall 31 and is close to the pivot axis of the door body 3. The pivot axis of the door body 3 is close to the first body side wall.

[0096] The front wall 31 and the side wall 33 of the door body 3 intersect to form a first side edge W, and the side wall 33 and the rear wall 32 intersect to form a second side edge N. When the door body 3 is closed, the first side edge W is located on the side of the second side edge N away from the box body 1.

[0097] It should be noted that when both the front door wall 31 and the side door wall 33 are flat walls, the intersection line of the plane where the front door wall 31 is located and the plane where the side door wall 33 is located is the first side edge W. When the rounded transition is set at the intersection of the front door wall 31 and the side door wall 33, a first side edge W is formed along the height direction of the door body 3 (i.e. Figure 1 ). For ease of description, any straight line on this curved surface extending in the height direction of the door body 3 represents a first side edge W. Similarly, the intersection of the rear door wall 32 and the side door wall 33 is rounded, and the second side edge N can be represented by the intersection line of the planes on which the rear door wall 32 and the side door wall 33 lie, or by a straight line located close to and parallel to the intersection line.

[0098] In some embodiments of the present application, a door seal is provided on the rear wall 32 of the door body 3. When the door body 3 is closed, the door seal surrounds the access opening, effectively sealing it. When the door body 3 is closed, the door seal abuts the front surface of the cabinet 1, effectively sealing the connection between the door body 3 and the cabinet 1. This ensures that the door body 3 seals the access opening, preventing cold air from escaping.

[0099] In this application, Indicates the opening angle of the door body 3.

[0100] In some embodiments of the present application, the door body 3 opens at an angle of The door front wall 31 is parallel to the plane where the take-in / put-out opening is located.

[0101] In some embodiments of the present application, the door body 3 opens at an angle of The door rear wall 32 is perpendicular to the plane where the access opening is located.

[0102] In some embodiments of the present application, the door body 3 opens at an angle of The door side wall 33 is parallel to the plane where the access opening is located.

[0103] In some embodiments of the present application, the door body 3 opens at an angle of The opening angle of the door 3 when it is opened relative to the box body 1 to open the access opening Is a positive number.

[0104] The door body 3 is closed in the direction When the movement continues to further squeeze the door seal, the opening angle of the door body 3 becomes a negative number.

[0105] In some embodiments of the present application, the door body 3 opens at an angle of It is marked as closed.

[0106] In some embodiments of the present application, when the door body 3 is closed, its opening angle is That is, when the door body 3 is closed, the deformation of the door body 3 extruding the door seal is relative to The larger the door 3 is, the better the sealing effect between the door body 3 and the box body 1 is. In some embodiments of the present application, when the door body 3 is closed, its opening angle is

[0107] In some embodiments of the present application, the hinge assembly includes a first hinge member and a second hinge member, and the first hinge member and the second hinge member cooperate with each other and can rotate relative to each other, so that the door body 3 and the box body 1 can rotate relative to each other.

[0108] In some embodiments of the present application, the first hinge is disposed on the housing 1 near one of the housing side walls. In this embodiment, the first hinge is disposed near the first housing side wall. The second hinge is disposed on the end of the door 3 near the first hinge. The first hinge and the second hinge cooperate to allow the housing 1 and the door 3 to rotate relative to each other.

[0109] Reference Figures 2 to 4 , the first hinge member includes a hinge plate 4. Specifically, the hinge plate 4 includes a connecting portion 41 connected to the box body 1 and an extending portion 42 extending forward from the connecting portion 41. The extending portion 42 can be set to be parallel to the top wall of the box body 1. The connecting portion 41 can be fastened to the top wall of the box body 1 by fasteners such as screws, pins and bolts. Specifically, for the hinge at the upper end of the door body 3, the connecting portion 41 is connected to the top wall of the box body 1. For the hinge at the lower end of the door body 3, the connecting portion 41 is connected to the front end surface of the box body 1.

[0110] In some embodiments of the present application, the first hinge member includes a first shaft 5 and a guide portion 7. The first shaft 5 and the guide portion 7 are both connected to the box body 1.

[0111] In some embodiments of the present application, the first shaft 5 and the guide portion 7 are both disposed on the hinge plate 4. Specifically, the first shaft 5 is located on the side of the guide portion 7 that is away from the side wall of the first body. This arrangement allows the first shaft 5 and the guide portion 7 to be disposed along the width of the housing 1, reducing the space occupied by them along the front-to-back direction of the housing 1 and making the structure of the first hinge more compact.

[0112] The second hinge member includes a second shaft 6 and a guide portion 8. The second shaft 6 and the guide portion 8 are located on the door body 3 near the end of the first hinge member. The second shaft 6 is located on the side of the guide portion 8 near the door front wall 31.

[0113] Among them, the first axis 5 is adapted to the guide part 8; the second axis 6 is adapted to the guide part 7; in the process of rotating the door body 3 to open or close, the first axis 5 moves relative to the guide part 8, and the second axis 6 moves relative to the guide part 7, so that the door body 3 moves at least a certain distance along the width direction of the box body 1 while rotating to open the access opening.

[0114] The center axis of the first shaft 5 is denoted as the first center axis Q. The center axis of the second shaft 6 is denoted as the second center axis P. When the door body 3 is opened, the trajectory of the second center axis P relative to the guide portion 7 is denoted as the guide trajectory S.

[0115] In some embodiments of the present application, the guide trajectory S is a curve. The curved guide trajectory S convexly extends away from the plane of the access opening. Specifically, the guide trajectory S extends from its end away from the first body sidewall to a side closer to the first body sidewall and away from the plane of the access opening, and then to a side closer to the first body sidewall and the plane of the access opening. This guide trajectory S extends in two stages, resulting in a simple trajectory extension, which improves the smoothness of the movement of the second axis relative to the guide portion.

[0116] In some embodiments of the present application, the guide trajectory line S is an arc, so that the movement of the second shaft 6 relative to the guide portion 7 is smoother.

[0117] In some embodiments of the present application, the guide portion 7 is configured as a guide groove. The guide groove is a connected curved groove that protrudes toward a side away from the plane where the take-in / put-out opening is located.

[0118] In some embodiments of the present application, the guide groove is an arc groove.

[0119] In some embodiments of the present application, the guide groove includes a guide groove bottom, a circumferential guide groove wall surrounding the guide groove bottom, and a guide groove opening defined by the circumferential guide groove wall and disposed opposite the guide groove bottom. The second shaft 65 extends into the guide groove through the guide groove opening. The circumferential sidewalls of the second shaft 65 cooperate with the circumferential guide groove wall of the guide groove to guide the second shaft 65 as it moves relative to the guide groove. The guide groove configured as described above guides the second shaft 6 via its circumferential guide groove wall, making relative motion more stable.

[0120] In some embodiments of the present application, the guide groove comprises a guide notch provided on the hinge plate 4. The second shaft 6 passes through the guide notch, and the circumferential sidewalls of the second shaft 6 cooperate with the hinge plate 4 surrounding the guide notch to guide the second shaft 6 as the second shaft 65 moves relative to the guide groove. This arrangement achieves the purpose of the guide groove guiding the second shaft 6 and is easy to manufacture.

[0121] Reference Figure 5 In some embodiments of the present application, the center of the arc-shaped guide track line S is recorded as the guide center O. The guide center O is located on the side of the guide track line S close to the plane where the pick-up and drop-out port is located. The radius of the arc-shaped guide track line S is recorded as the guide radius R.

[0122] In some embodiments of the present application, 8 mm ≤ R ≤ 12 mm.

[0123] When R is less than 8 mm, the guide radius R is too small and the curvature of the guide trajectory S is too large, resulting in a too rapid change in the movement speed of the second shaft 6 relative to the guide portion 7 .

[0124] When 12mm<R, the guide radius R is too large and the curvature of the guide trajectory line S is too small, resulting in too small a change in the movement speed of the second shaft 6 relative to the guide part 7, and the length of the guide trajectory line is too long. The guide part 7 occupies a large space of the hinge plate 4, resulting in a decrease in the strength of the hinge plate 4 and also a decrease in the strength of the guide part 7, thereby reducing the service life of the hinge assembly.

[0125] When 8mm≤R, it is possible to avoid the curvature of the guide track line S being too large, which would cause the movement speed of the second shaft 6 relative to the guide portion 7 to change too quickly, thereby improving the stability of the movement of the door body 3 relative to the box body 1.

[0126] When R≤12mm, avoid the guide trajectory line S being too small, which will cause the movement speed of the second axis 6 relative to the guide part 7 to be too slow, so as to avoid the length of the guide trajectory line being too long, reduce the space occupied by the guide part 7 on the hinge plate 4, avoid the strength of the hinge plate 4 from being reduced, and ensure the service life of the hinge assembly.

[0127] The above arrangement of 8mm≤R≤12mm, on the one hand, stabilizes the movement of the second shaft 6 relative to the guide portion 7, thereby improving the stability of the movement of the door body 3 relative to the housing 1. On the other hand, the area occupied by the guide portion 7 on the hinge plate 4 is limited, thereby ensuring the strength of the hinge plate 4 and the guide portion 7, effectively ensuring the service life of the hinge assembly.

[0128] In the projection of the plane where the top wall of the box body 1 is located, the guide circle center O is located on the side of the first central axis Q close to the plane where the take-in and put-out opening is located and the side wall of the first body.

[0129] In some embodiments of the present application, the point where the guide track line S is at the maximum distance from the plane where the access port is located is recorded as the first guide point P1. The first central axis Q is located on the side of the first guide point P1 close to the plane where the access port is located and away from the side wall of the first body.

[0130] In some embodiments of the present application, when the door body 3 is opened, the door body 3 is opened at an angle of When the distance between the second central axis P and the side wall of the first body is the smallest, the second central axis P is located at the first extreme guide point P1' of the guide trajectory line S.

[0131] When the door 3 opens at an angle When the second central axis P is at the maximum distance from the side wall of the first body, the second central axis P is located at the second extreme guide point P2' of the guide trajectory line S.

[0132] In some embodiments of the present application, in the projection of the plane where the top wall of the box body 1 is located, in the direction perpendicular to the plane where the pick-up and release port is located, the distance between the first center axis Q and the first guide point P1 is recorded as |QP1|1; the distance between the first center axis Q and the first extreme guide point P1` is recorded as |QP1`|1; the distance between the first center axis Q and the second extreme guide point P2` is recorded as |QP2`|1.

[0133] In some embodiments of the present application, in the projection of the plane on which the top wall of the box 1 lies, the first guide point P1, the first extreme guide point P1', and the second extreme guide point P2' are all located on the side of the first central axis Q away from the plane on which the access port lies. That is, the segment of the guide trajectory S extending from the first extreme guide point P1' through the first guide point P1 to the second extreme guide point P2' lies on the side of the first central axis Q away from the plane on which the access port lies.

[0134] In some embodiments of the present application, |QP1`|1≤|QP1|1, |QP2`|1≤|QP1|1. In this case, |QP1|1=|QP1`|1 and |QP1|1=|QP2`|1 do not hold simultaneously.

[0135] In some embodiments of the present application, 0 mm ≤ |QP1| 1 ≤ 4 mm.

[0136] When 4mm<|QP1|1, when the second axis 6 moves to the point where the distance between the guide part 7 and the plane where the pick-up and release port is located is the largest, the distance between the second axis 6 and the first axis 5 in the direction perpendicular to the plane where the pick-up and release port is located is too large, resulting in the door body 3 relative to the box body 1. The displacement in the direction perpendicular to the plane where the pick-up and release port is too large, resulting in an imbalance in the movement of the door body 3 relative to the box body 1 in the width direction and the movement in the front-to-back direction, and the inability to effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0137] In the present application, the setting of 0mm≤|QP1|1≤4mm enables the second axis 6 to move to the point where the distance between the guide portion 7 and the plane where the pick-up and release port is located is the largest. In the direction perpendicular to the plane where the pick-up and release port is located, the second axis 6 is close to the first axis 5, effectively controlling the displacement of the door body 3 relative to the box body 1 in the direction perpendicular to the plane where the pick-up and release port is located, so as to control the movement of the door body 3 relative to the box body 1 in the width direction and the front-to-back direction, so as to reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3, so that the door body 3 can be opened to a larger angle.

[0138] In some embodiments of the present application, 0mm≤|QP1`|1≤2mm.

[0139] When 2mm<|QP1`|1, when the second axis 6 moves to the point where the distance between the guide part 7 and the side wall of the first body is the smallest, the distance between the second axis 6 and the first axis 5 in the direction perpendicular to the plane where the take-in and put-out port is located is too large, resulting in the door body 3 relative to the box body 1. The displacement in the direction perpendicular to the plane where the take-in and put-out port is too large, resulting in an imbalance in the movement of the door body 3 relative to the box body 1 in the width direction and the movement in the front-to-back direction, and the inability to effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0140] In the present application, the setting of 0mm≤|QP1`|1≤2mm enables the second axis 6 to move to the point where the distance between the guide portion 7 and the side wall of the first body is the minimum. In the direction perpendicular to the plane where the take-in and put-out port is located, the second axis 6 is close to the first axis 5, effectively controlling the displacement of the door body 3 relative to the box body 1 in the direction perpendicular to the plane where the take-in and put-out port is located, so as to control the movement of the door body 3 relative to the box body 1 in the width direction and the front-to-back direction, so as to reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3, so that the door body 3 can be opened to a larger angle.

[0141] In some embodiments of the present application, 0mm≤|QP2`|1≤3mm.

[0142] When 3mm<|QP2`|1, when the second axis 6 moves to the point where the distance between the guide part 7 and the side wall of the first body is the largest, the distance between the second axis 6 and the first axis 5 in the direction perpendicular to the plane where the take-in and put-out port is located is too large, resulting in the door body 3 relative to the box body 1. The displacement in the direction perpendicular to the plane where the take-in and put-out port is too large, resulting in an imbalance in the movement of the door body 3 relative to the box body 1 in the width direction and the movement in the front-to-back direction, and the inability to effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0143] In the present application, the setting of 0mm≤|QP2`|1≤3mm enables the second axis 6 to move to the point where the distance between the guide portion 7 and the side wall of the first body is the largest. In the direction perpendicular to the plane where the take-in and put-out port is located, the second axis 6 is close to the first axis 5, effectively controlling the displacement of the door body 3 relative to the box body 1 in the direction perpendicular to the plane where the take-in and put-out port is located, so as to control the movement of the door body 3 relative to the box body 1 in the width direction and the front-to-back direction, so as to reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3, so that the door body 3 can be opened to a larger angle.

[0144] In the above, the limitations of 0mm≤|QP1|1≤4mm, 0mm≤|QP1`|1≤2mm, and 0mm≤|QP2`|1≤3mm jointly limit the overall trend of the guide trajectory line S, so that during the opening process of the door body 3, in the direction perpendicular to the plane where the pick-up and release port is located, the second axis 6 is close to the first axis 5 throughout the entire process, so as to effectively control the displacement of the door body 3 relative to the box body 1 in the direction perpendicular to the plane where the pick-up and release port is located, so as to control the movement of the door body 3 relative to the box body 1 in the width direction and the front-to-back direction, so that the total displacement of each stage can meet the needs of each stage in the process of opening the door body 3, and at the same time reduce the restriction of the space limited by the cabinet 2 on the movement of the door body 3, so that the door body 3 can be opened to a larger angle.

[0145] In some embodiments of the present application, 20°≤∠P1`OP2`≤30°.

[0146] When ∠P1`OP2` is less than 20°, ∠P1`OP2` is too small, the length of the guide trajectory is too small, the length of the guide portion 7 is too small, and the number of relative frictions when the second shaft 6 moves relative to the guide portion 7 is large, which increases the wear of the second shaft 6 and the guide portion 7 and reduces the life of the hinge assembly.

[0147] When 30°<∠P1`OP2`, ∠P1`OP2` is too large, the length of the guide trajectory is too large, the length of the guide part 7 is too large, and the guide part 7 occupies a large space of the hinge plate 4, resulting in a decrease in the strength of the hinge plate 4 and the guide part 7, thereby reducing the service life of the hinge assembly.

[0148] When 20°≤∠P1`OP2`, the length of the guide trajectory is limited to a reasonable range, the number of relative frictions of the second shaft 6 relative to the guide part 7 is limited, reducing the wear of the second shaft 6 and the guide part 7 and ensuring the life of the hinge assembly.

[0149] When ∠P1`OP2`≤30°, the length of the guide track line is limited to a reasonable range, reducing the space occupied by the guide portion 7 on the hinge plate 4, avoiding a reduction in the strength of the hinge plate 4, and ensuring the service life of the hinge assembly.

[0150] When the setting of 20°≤∠P1`OP2`≤30° limits the length of the guide trajectory line (guide part 7), on the one hand, the number of relative frictions of the second shaft 6 relative to the guide part 7 is reduced to reduce the wear of the second shaft 6 and the guide part 7; on the other hand, the space occupied by the guide part 7 on the hinge plate 4 is reduced, thereby avoiding the reduction of the strength of the hinge plate 4 and ensuring the service life of the hinge assembly.

[0151] In some embodiments of the present application, 12°≤∠P1`OP1≤20°.

[0152] The distance that the second shaft 6 moves relative to the guide portion 7 between the first guide point P1 and the first limit guide point P1 ′ is recorded as the first distance.

[0153] When ∠P1`OP1 is less than 12°, ∠P1`OP1 is too small, the first stroke of the second axis 6 relative to the guide part 7 between the first guide point P1 and the first limit guide point P1` is too small, and the first stroke of the door body 3 relative to the box body 1 in the width direction and the front-to-back direction is too small, which cannot effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0154] When 20°<∠P1`OP1, ∠P1`OP1 is too large, and in the process of the second axis 6 moving relative to the guide part 7 between the first guide point P1 and the first limit guide point P1`, there is a situation where the distance between the second axis 6 and the first axis 5 in the direction perpendicular to the plane where the pick-up and release port is located is too large, resulting in the door body 3 moving relative to the box body 1 in at least one section of the direction perpendicular to the plane where the pick-up and release port is located. The displacement is too large, resulting in an imbalance between the movement of the door body 3 relative to the box body 1 in the width direction and the movement in the front-to-back direction, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0155] When 12°≤∠P1`OP1, the first stroke of the second axis 6 relative to the guide part 7 between the first guide point P1 and the first limit guide point P1` meets the movement requirements of the door body 3, and the first stroke with appropriate movement of the door body 3 in the width direction and the front-to-back direction relative to the box body 1 meets the movement requirements of the door body 3, which can effectively reduce the restriction of the space limited by the cabinet 2 on the movement of the door body 3.

[0156] When ∠P1`OP1≤20°, during the movement of the second axis 6 relative to the guide part 7 between the first guide point P1 and the first extreme guide point P1`, the second axis 6 approaches the first axis 5 in the direction perpendicular to the plane where the pick-up and release port is located, effectively controlling the movement of the door body 3 relative to the box body 1 along the width direction and the front-to-back direction, and can effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0157] In this application, the setting of 12°≤∠P1`OP1≤20° enables the second axis 6 to move to the guide part 7. During the movement between the first guide point P1 and the first extreme guide point P1`, in the direction perpendicular to the plane where the pick-up and release port is located, the movement amount of the door body 3 relative to the box body 1 along the width direction and the movement amount along the front-to-back direction are appropriate, and the stroke appropriately meets the movement requirements of the door body 3, so as to more efficiently reduce the restriction of the space limited by the cabinet 2 on the movement of the door body 3.

[0158] In some embodiments of the present application, 7°≤∠P2`OP1≤11°.

[0159] The movement distance of the second shaft 6 relative to the guide portion 7 between the first guide point P1 and the second limit guide point P2' is recorded as the second distance.

[0160] When ∠P2`OP1 is less than 7°, ∠P2`OP1 is too small, the second stroke of the second axis 6 relative to the guide part 7 between the first guide point P1 and the second limit guide point P2` is too small, and the second stroke of the door body 3 relative to the box body 1 in the width direction and the front-to-back direction is too small, which cannot effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0161] When 11°<∠P2`OP1, ∠P2`OP1 is too large, and in the process of the second axis 6 moving relative to the guide part 7 between the first guide point P1 and the second extreme guide point P2`, there is a situation where the distance between the second axis 6 and the first axis 5 in the direction perpendicular to the plane where the take-in and put-out port is located is too large, resulting in the door body 3 moving relative to the box body 1 in at least one section of the direction perpendicular to the plane where the take-in and put-out port is located. The displacement is too large, resulting in an imbalance between the movement of the door body 3 relative to the box body 1 in the width direction and the movement in the front-to-back direction, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0162] When 7°≤∠P2`OP1, the second stroke of the second axis 6 relative to the guide part 7 between the first guide point P1 and the second extreme guide point P2` meets the movement requirements of the door body 3, and the second stroke with appropriate movement of the door body 3 in the width direction and the front-to-back direction relative to the box body 1 meets the movement requirements of the door body 3, which can effectively reduce the restriction of the space limited by the cabinet 2 on the movement of the door body 3.

[0163] When ∠P2`OP1≤11°, during the movement of the second axis 6 relative to the guide part 7 between the first guide point P1 and the second extreme guide point P2`, the second axis 6 approaches the first axis 5 in the direction perpendicular to the plane where the pick-up and release port is located, effectively controlling the movement of the door body 3 relative to the box body 1 along the width direction and the front-to-back direction, and can effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0164] In this application, the setting of 7°≤∠P2`OP1≤11° enables the second axis 6 to move to the guide part 7. During the movement between the first guide point P1 and the second extreme guide point P2`, in the direction perpendicular to the plane where the pick-up and release port is located, the movement amount of the door body 3 relative to the box body 1 along the width direction and the movement amount along the front-to-back direction are appropriate, and the stroke is appropriate, so as to more efficiently reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0165] In some embodiments of the present application, 1.6≤∠P1`OP1:∠P2`OP1≤2.

[0166] When ∠P1`OP1:∠P2`OP1<1.6, ∠P1`OP1:∠P2`OP1 is too small, the first stroke is too small, and the movement of the door body 3 relative to the cabinet 1 in the width direction and the movement in the front-to-back direction are appropriate. The first stroke is too small and cannot effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3. In addition, the ratio of the first stroke to the second stroke is too small, and the distribution of the first and second strokes of the door body 3 relative to the cabinet 1 is unbalanced, which cannot meet the displacement requirements of the door body 3 at each stage of opening.

[0167] When 2 < ∠P1`OP1:∠P2`OP1, ∠P1`OP1:∠P2`OP1 is too large, the first stroke is too large, and the distance between the second axis 6 and the first axis 5 in the direction perpendicular to the plane of the access port is too large. This causes the door body 3 to have an excessively large displacement in the direction perpendicular to the plane of the access port during at least one section of its movement relative to the cabinet 1. This leads to an imbalance between the movement of the door body 3 in the width direction and the movement in the front-to-back direction relative to the cabinet 1, and fails to effectively reduce the restriction on the movement of the door body 3 imposed by the space defined by the cabinet 2. In addition, the ratio of the first stroke to the second stroke is too large, resulting in an imbalance in the distribution of the first and second strokes of the door body 3 relative to the cabinet 1, which fails to meet the displacement requirements of the door body 3 at each stage of opening.

[0168] When 1.6 ≤ ∠P1`OP1:∠P2`OP1, the first stroke satisfies the movement requirements of the door body 3. A first stroke with an appropriate amount of movement of the door body 3 in the width direction and in the front-to-back direction relative to the cabinet 1 satisfies the movement requirements of the door body 3, effectively reducing the restrictions imposed by the space confined by the cabinet 2 on the movement of the door body 3. Furthermore, the ratio of the first stroke to the second stroke is limited within an appropriate range to control the relative amounts of the first and second strokes of the door body 3 relative to the cabinet 1 during movement, thereby satisfying the displacement requirements of the door body 3 at each stage of opening.

[0169] When ∠P1`OP1 ≤ 20°, during the first stroke, the second axis 6 approaches the first axis 5 in a direction perpendicular to the plane of the access opening, effectively controlling the widthwise and front-to-back motion of the door 3 relative to the cabinet 1, thereby effectively reducing the restrictions imposed by the space confined by the cabinet 2 on the movement of the door 3. Furthermore, the ratio of the first to second strokes is limited within an appropriate range to control the relative magnitude of the first and second strokes of the door 3 relative to the cabinet 1, thereby meeting the displacement requirements of the door 3 at each stage of opening.

[0170] In the present application, the setting of 1.6≤∠P1`OP1:∠P2`OP1≤2 ensures that during the movement of the first stroke, in a direction perpendicular to the plane where the access opening is located, the amount of movement of the door body 3 relative to the cabinet 1 in the width direction and the amount of movement in the front-to-back direction are appropriate, and the stroke appropriately meets the movement requirements of the door body 3, thereby more efficiently reducing the impact of the space defined by the cabinet 2 on the movement of the door body 3. In addition, the ratio of the first stroke to the second stroke is limited to an appropriate range to control the relative amounts of the first stroke and the second stroke of the door body 3 relative to the cabinet 1 during movement, thereby meeting the displacement requirements of the door body 3 at each stage of opening.

[0171] In the projection of the plane where the top wall of the box body 1 is located, the distance between the first central axis Q and the guide circle center O in the direction perpendicular to the plane where the pick-up and release opening is located is recorded as |QO|1. 3≤|QO|1:|QP1|1.

[0172] When |QO|1:|QP1|1<3, |QO|1:|QP1|1 is too small, and when the second axis 6 moves to the point where the distance between the guide part 7 and the plane where the pick-up and release port is located is the largest, the distance between the second axis 6 and the first axis 5 in the direction perpendicular to the plane where the pick-up and release port is located is too large, resulting in the door body 3 relative to the box body 1. The displacement in the direction perpendicular to the plane where the pick-up and release port is located is too large, resulting in an imbalance in the movement of the door body 3 relative to the box body 1 in the width direction and the movement in the front-back direction, and cannot effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0173] In the present application, the setting of 3≤|QO|1:|QP1|1 enables the second axis 6 to move to the point where the distance between the guide portion 7 and the plane where the pick-up and release port is located is the largest. In the direction perpendicular to the plane where the pick-up and release port is located, the second axis 6 is close to the first axis 5, effectively controlling the displacement of the door body 3 relative to the box body 1 in the direction perpendicular to the plane where the pick-up and release port is located, so as to control the movement of the door body 3 relative to the box body 1 in the width direction and the front-to-back direction, so as to reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3, so that the door body 3 can be opened to a larger angle.

[0174] Reference Figure 6 When the door body 3 is opened, the second axis 6 moves relative to the guide portion 7, and the trajectory line of the first central axis Q moving relative to the guide portion 8 is recorded as the guide trajectory line F.

[0175] In some embodiments of the present application, the guide trajectory F includes a first guide segment, which extends from an end away from the door side wall 33 to a side close to the door side wall 33 and away from the door front wall 31 .

[0176] In some embodiments of the present application, the distance between the first guide section and the second central axis P decreases first and then increases from the end thereof away from the door side wall 33 .

[0177] In some embodiments of the present application, the guide trajectory line F includes a second guide segment, which extends from an end thereof away from the door side wall 33 to a side close to the door side wall 33 and the door front wall 31 .

[0178] In some embodiments of the present application, the distance between the second guide section and the second central axis P increases first and then decreases from the end thereof away from the door side wall 33 .

[0179] In some embodiments of the present application, the guide trajectory F includes a first guide segment and a second guide segment connected to each other. The guide trajectory F extends from the end of the first guide segment distal from the second guide segment toward a side proximal to the door sidewall 33 and distal to the door front wall 31, to H, and then extends from H toward a side proximal to the door sidewall 33 and the door front wall 31. This defines the extension trend of the trajectory along which the guide portion guides the movement of the central axis of the first shaft. The extension trend of the guide trajectory is divided into two segments, resulting in a simple trajectory extension trend, which improves the smoothness of the movement of the first shaft relative to the guide portion.

[0180] In some embodiments of the present application, the guide trajectory F is curved. The curved guide trajectory F protrudes toward the side away from the door front wall 31. The guide trajectory F includes a first guide segment and a second guide segment connected to the end of the first guide segment near the door side wall 33. Specifically, the guide trajectory F extends from its end away from the door side wall 33 toward a side near the door side wall 33 and away from the door front wall 31, and then toward a side near both the door side wall 33 and the door front wall 31.

[0181] In some embodiments of the present application, the distance between the end of the guide track line F away from the door side wall 33 and the door front wall 31 is smaller than the distance between the end of the guide track line F close to the door side wall 33 and the door front wall 31 .

[0182] In some embodiments of the present application, the point on the guide trajectory F that is away from the door sidewall 33 and has the shortest distance from the door front wall 31 is recorded as the first guide point K. The point on the end of the guide trajectory F that is close to the door sidewall 33 and has the shortest distance from the door front wall 31 is recorded as the second guide point J. The point on the guide trajectory F that is the longest distance from the door front wall 31 is recorded as the third guide point H.

[0183] The point on the guide portion 8 where the distance between the end of the guide portion 8 away from the door sidewall 33 and the door front wall 31 is the minimum is recorded as the first guide boundary point K'. The point on the end of the guide portion 8 closer to the door sidewall 33 where the distance between the door front wall 31 is the minimum is recorded as the second guide boundary point J'. The point where the distance between the guide portion 8 and the door front wall 31 is the maximum is recorded as the third guide boundary point H'.

[0184] The first guide boundary point K', the second guide boundary point J', and the third guide boundary point H' are all located on the wall surface of the guide portion 8 (guide groove) that is used to cooperate with the first shaft 5. For example, when the guide portion 8 is a guide groove, the first guide boundary point K', the second guide boundary point J', and the third guide boundary point H' are all located on the inner wall of the guide groove.

[0185] In some embodiments of the present application, the first guide boundary point K' is located on the side of the starting guide point K close to the door front wall 31. The straight line K'K between the first guide boundary point K' and the first guide point K is perpendicular to the door front wall 31. The distance between the first guide boundary point K' and the first guide point K is equal to the radius of the first axis 5.

[0186] In some embodiments of the present application, the second guide boundary point J' is located on the side of the second guide point J close to the door front wall 31. The straight line J'J between the second guide boundary point J' and the second guide point J is perpendicular to the door front wall 31. The distance between the second guide boundary point J' and the second guide point J is equal to the radius of the first axis 5.

[0187] In some embodiments of the present application, the third guide boundary point H' is located on the side of the third guide point H away from the door front wall 31. The straight line H'H between the third guide boundary point H' and the third guide point H is perpendicular to the door front wall 31. The distance between the third guide boundary point H' and the third guide point H is equal to the radius of the first axis 5.

[0188] As described above, when actually determining the positions of the first guide point K, the second guide point J, and the third guide point H, the positions of the first guide boundary point K', the second guide boundary point J', and the third guide boundary point H', and the radius of the first axis 5 can be measured by a measuring tool. Then, based on the relative relationship that the distance between the first guide boundary point K' and the first guide point K is equal to the radius of the first axis 5, the distance between the second guide boundary point J' and the second guide point J is equal to the radius of the first axis 5, and the distance between the third guide boundary point H' and the third guide point H is equal to the radius of the first axis 5, the positions of the corresponding first guide point K, the second guide point J, and the third guide point H can be determined.

[0189] It should be noted that the distance between the first guide boundary point K` and the first guide point K is equal to the radius of the first axis 5, the distance between the second guide boundary point J` and the second guide point J is equal to the radius of the first axis 5, and the distance between the third guide boundary point H` and the third guide point H is equal to the radius of the first axis 5. The "equal" includes deviations caused by processing errors, etc.

[0190] It can be set that the above “equal” includes the case where the difference between the two equal objects is any value between 0 and 2 mm.

[0191] In some embodiments of the present application, when the door body 3 is in a closed state, the first central axis Q is located at the first guide point K of the guide trajectory line F.

[0192] In some embodiments of the present application, under the constraints of the guide portion 8, the guide portion 7, the first axis 5 and the second axis 6, when the door body 3 is opened to the maximum angle, the first center axis Q is located at the second guide point J of the guide trajectory line F.

[0193] It should be noted that, under the premise that the door front wall 31 and the door side wall 33 are arranged perpendicularly, the direction perpendicular to the door front wall 31 is the same as the direction parallel to the door side wall 33. And the direction perpendicular to the door side wall 33 is the same as the direction parallel to the door front wall 31.

[0194] In the case where the door front wall 31 and the door side walls 33 are not arranged perpendicularly, the direction perpendicular to the door front wall 31 only refers to the distance relative to and perpendicular to the door front wall 31, and is not necessarily parallel to the door side walls 33. Similarly, the direction perpendicular to the door side walls 33 only refers to the distance relative to and perpendicular to the door side walls 33, and is not necessarily parallel to the door front wall 31.

[0195] Reference Figure 6 In a plane projection parallel to the top wall of the box body 1, the distance between the second central axis P and the third guide point H along a direction perpendicular to the door side wall 33 is denoted as |PH|2. Where, 0mm≤|PH|2≤5mm.

[0196] When 5mm<|PH|2, |PH|2 is too large, and the distance between the second axis 6 and the third guide point H on the guide trajectory line that is the farthest away from the door front wall 31 in the direction perpendicular to the door side wall 33 is too large; during the movement of the door body 3 relative to the box body 1, when the first center axis Q moves to the third guide point H, the distance between the second center axis and the first center axis in the direction perpendicular to the door side wall 33 is too large, and the straight line where the first center axis and the second center axis are located is too inclined at an angle relative to the plane where the pick-up and release port is located. At this time, the stability of the movement of the door body 3 relative to the box body 1 is poor.

[0197] In the present application, with the setting of 0mm≤|PH|2≤5mm, the second axis 6 is close to the third guide point H on the guide trajectory line which is the farthest away from the door front wall 31 in the direction perpendicular to the door side wall 33; when the door body 3 moves relative to the box body 1, the first center axis Q moves to the third guide point H, and the second center axis is close to the first center axis in the direction perpendicular to the door side wall 33, thereby effectively ensuring the stability of the movement of the door body 3 relative to the box body 1.

[0198] Reference Figure 6In the plane projection parallel to the top wall of the box body 1, the distance between the second central axis P and the first guide point K in the direction perpendicular to the door front wall 31 is recorded as |PK|1. Wherein, 0mm≤|PK|1≤3mm.

[0199] When 3mm<|PK|1, |PK|1 is too large, and the distance between the second center axis P and the first guide point K on the guide trajectory line that is the largest distance from the door side wall 33 in the direction perpendicular to the door front wall 31 is too large; in the process of the door body 3 moving relative to the box body 1, when the first center axis Q is located at the first guide point K, the distance between the second center axis and the first center axis in the direction perpendicular to the door front wall 31 is too large, and the straight line where the first center axis and the second center axis are located is too inclined at an angle relative to the plane where the pick-up and drop-out port is located. At this time, the stability of the door body 3 moving relative to the box body 1 is poor.

[0200] In the present application, the setting of 0mm≤|PK|1≤3mm is that, in the direction perpendicular to the door front wall 31, the second axis 6 is close to the first guide point K on the guide trajectory line which is the longest distance from the door side wall 33; during the movement of the door body 3 relative to the box body 1, when the door body 3 is closed, when the first center axis Q is located at the first guide point K, in the direction perpendicular to the door side wall 33, the second center axis P is close to the first center axis, thereby effectively ensuring the stability of the movement of the door body 3 relative to the box body 1.

[0201] In some embodiments of the present application, the first guiding point K is located on a side of the second central axis P away from the door front wall 31 .

[0202] like Figure 7-Figure 20 As shown, the movement of the first shaft 5 along the guide portion 8 is equivalent to the movement of the first central axis Q along the guide trajectory K. The movement of the second shaft 6 along the guide portion 7 is equivalent to the movement of the second central axis P along the guide trajectory S, so that the door body 3 can move a certain distance inward (toward the side wall of the second body) while rotating, so that the door body 3 does not interfere with the cabinet 2, ensuring that the door body 3 can be effectively opened.

[0203] In some embodiments of the present application, during the opening of the door body 3, the first axis 5 moves relative to the guide part 8 throughout the entire process, the second axis 6 moves relative to the guide part 7 throughout the entire process, and the door body 3 rotates around a point that maintains dynamic changes relative to the box body 1 throughout the entire process.

[0204] In some embodiments of the present application, within the projection of the plane where the top wall of the box body 1 is located, the line segment PQ is recorded as the axis line segment PQ. The midpoint of the axis line segment PQ is recorded as the axis center point I. During the opening process of the door body 3, the first axis 5 moves relative to the guide portion 8 throughout the entire process, the second axis 6 moves relative to the guide portion 7 throughout the entire process, and the door body 3 rotates around the point (axis center point I) that maintains dynamic changes relative to the box body 1 throughout the entire process. Under the above settings, during the opening process of the door body 3, the first center axis Q moves relative to the guide trajectory line F, the second center axis P moves relative to the guide trajectory line S, and the door body 3 rotates with the axis center point I as the instantaneous rotation center.

[0205] During the above process of opening the door body 3, the position of the first axis 5 relative to the box body 1 remains unchanged, the position of the second axis 6 relative to the box body 1 keeps changing, the position and length of the axis line segment PQ relative to the box body 1 keep changing, the position of the center point I of the axis relative to the box body 1 keeps changing, and the rotation center axis of the door body 3 relative to the box body 1 keeps changing.

[0206] The guide trajectory F includes a second guide point J near one end of the door sidewall 33 and a first guide point K away from the door sidewall 33. The guide trajectory F extends from the first guide point K toward a side near the door sidewall 33 and away from the door front wall 31 to a third guide point H, and then extends from the third guide point H toward a side near the door sidewall 33 and the door front wall 31 to the second guide point J.

[0207] In some embodiments of the present application, the guide trajectory line F is a smooth convex curve to make the movement of the first shaft 5 relative to the guide portion 8 smoother.

[0208] like Figure 7-Figure 20 As shown, with the first axis 5 and the guide portion 7 (box body 1) provided on the box body 1 as stationary reference objects, the movement of the second axis 6 along the guide portion 7 is equivalent to the movement of the second center axis P along the guide trajectory line S, and the movement of the guide portion 8 relative to the first axis 5 is equivalent to the movement of the guide trajectory line F through the first center axis Q, so that the door body 3 can move a certain distance inward (toward the side wall of the second body) while rotating, thereby compensating for the outward displacement of the first side edge W caused by the simple rotation of the door body 3, and effectively avoiding interference between the door body 3 and the cabinet 2 when the door body 3 is opened.

[0209] The movement of the door 3 relative to the housing 1 is equivalent to the relative movement of the two within the plane of the housing 1's top wall (or within a plane parallel to the housing 1's top wall); that is, the movement of the door 3 relative to the housing 1 is a two-dimensional relative movement. Within the plane of the housing 1's top wall, the movement of the guide portion 8 on the door 3 relative to the first shaft 5 on the housing 1 (or the movement of the second shaft 6 on the door 3 relative to the guide portion 7 on the housing 1) is equivalent to the movement of the door 3 relative to the hinge plate 4, and is also equivalent to the movement of the door 3 relative to the housing 1.

[0210] In the plane where the top wall of the box body 1 is located, on the side of the box body 1 close to the door body 3, a displacement coordinate system AOB is established. Specifically, in the displacement coordinate system AOB, OB is perpendicular to the plane where the access port is located, and OA is parallel to the plane where the access port is located (or perpendicular to the side wall of the first body). In the displacement coordinate system AOB, the direction from the side wall of the first body to the side wall of the second body is defined as the positive direction of the A axis, and the direction from the plane where the access port is located to the front wall 31 of the door when the door body 3 is closed (from back to front) is defined as the positive direction of the B axis.

[0211] It should be noted that, during the opening process of the door body 3 , the displacement coordinate system AOB remains stationary relative to the box body 1 and does not move as the door body 3 opens.

[0212] During the movement of the door body 3 relative to the box body 1, the door body 3 has a translational movement while rotating. Among them, the translational movement of the door body 3 is decomposed into a first direction movement perpendicular to the side wall of the first body (along the A axis) and a second direction movement perpendicular to the plane where the access port is located (along the B axis). Among them, the movement amount in the first direction perpendicular to the side wall of the first body (along the A axis) is recorded as the first direction displacement Among them, the first direction displacement When , it has an inward displacement; the first direction displacement When , it has an outward displacement. Among them, the first direction displacement The module is

[0213] The movement in the second direction perpendicular to the plane of the pick-up and release port (along the B axis) is recorded as the second direction displacement Among them, the second direction displacement When it moves forward, it has a displacement; the second direction displacement When , it has a displacement moving backward. Among them, the second direction displacement The module is

[0214] In some embodiments of the present application, the opening angle of the door body 3 is When the door is closed, the first axis 5 is located at the end of the guide portion 8 away from the door side wall 33, and the second axis 6 is located at the end of the guide portion 7 closer to the first body side wall. The above defines the position of the first axis relative to the guide portion and the position of the second axis relative to the guide portion when the door is closed, thereby defining the movement trends of the first axis relative to the guide portion and the second axis relative to the guide portion in the first stage of door opening, thereby defining the translation trend of the door relative to the cabinet in the first stage of door opening, thereby avoiding interference between the door and the cabinet, and preventing or reducing the door from squeezing the door seal.

[0215] In some embodiments of the present application, Figure 7 、 Figure 8 、 Figure 13-16 As shown, under the constraints of the aforementioned guide portion 8 and the first shaft 5, the guide portion 7 and the second shaft 6, the opening process of the door body 3 has a first stage. The first stage is as follows:

The first guide position K1 is located on the side of the starting guide position K0 away from the first side wall and the plane where the access port is located. The second guide point J1 is located on the side of the starting guide point J0 away from the first side wall and closer to the plane where the access port is located.

[0230] In some embodiments of the present application, the first midpoint I1 is located on the side of the starting midpoint I0 away from the side wall of the first body. Open to During the process, the center point I of the axis moves relative to the box body 1 toward the side away from the side wall of the first body.

[0231] Taking the box body 1 (hinge plate 4) as a reference, the door body 3 is composed of Open to During the process, the first direction displacement The door body 3 has a tendency to move inward to compensate for the outward displacement of the first side edge W caused by the simple rotation of the door body 3, so as to avoid the first side edge W colliding with the cabinet 2 and causing the door body 3 to be unable to continue opening; in addition, the door body 3 moves inward to reduce the restriction of the space defined by the cabinet 2 on the maximum angle that the door body 3 can open therein, so that the door body 3 of the refrigerator 100 placed in the cabinet 2 can be opened to a larger angle, which is convenient for users to take and put items.

[0232] In some embodiments of the present application, the first midpoint I1 is located on the side of the starting midpoint I0 away from the plane where the access port is located. Open to During the process, the center point I of the axis moves relative to the box body 1 toward the side away from the plane where the take-and-place opening is located.

[0259] Door 3 by Open to During the process, the center point I of the axis moves relative to the box body 1 toward the side away from the side wall of the first body.

[0260] In some embodiments of the present application, the door body 3 is composed of Open to During the process, the first direction displacement The door body 3 has a tendency to move inward to compensate for the outward displacement of the first side edge W caused by the simple rotation of the door body 3, so as to avoid the first side edge W colliding with the cabinet 2 and causing the door body 3 to be unable to continue opening; in addition, the door body 3 moves inward to reduce the restriction of the space defined by the cabinet 2 on the maximum angle that the door body 3 can open therein, so that the door body 3 of the refrigerator 100 placed in the cabinet 2 can be opened to a larger angle, which is convenient for users to take and put items.

Open to During the process, the center point I of the axis moves relative to the box body 1 toward the side close to the plane where the take-and-place opening is located.

[0263] In some embodiments of the present application, the second midpoint I2 is located on the side of the first midpoint I1 away from the side wall of the first body and close to the plane where the access opening is located. Open to During the process, the center point I of the axis moves relative to the box body 1 toward the side away from the side wall of the first body and close to the plane where the take-in and put-out opening is located.

[0264] In some embodiments of the present application, the box body 1 (hinge plate 4) is used as a reference, and the door body 3 is composed of Open to During the process, the first direction displacement Second direction displacement Door 3 by Open to During the process, the door body 3 has a tendency to move inward and backward while rotating to open the access opening.

[0265] In some embodiments of the present application, the door body 3 is composed of Open to In the process, That is, the door body 3 is made of Open to During the process, the translational movement of the door body 3 is mainly inward movement, mainly to compensate for the outward displacement of the first side edge W caused by the simple rotation of the door body 3, effectively avoiding the interference of the first side edge W with the cabinet 2; at the same time, it effectively reduces the restriction of the space defined by the cabinet 2 on the maximum angle that the door body 3 can open therein, so as to facilitate the door body 3 to be opened to a larger angle within the space defined by the cabinet 2.

[0266] In some embodiments of the present application, the door body 3 is composed of Open to The second direction displacement mode of the process No more than 3 doors Open to The second direction displacement mode of the process That is, the door body 3 is Open to The amount of backward movement during the process is not greater than Open to The above arrangement makes the door body 3 move forward. Open to During the process, the opening angle relative to the door body 3 is The state has an overall inward and forward translational displacement to compensate for the outward displacement of the first side edge W caused by the simple rotation of the door body 3, effectively avoiding the interference of the first side edge W with the cabinet 2; at the same time, efficiently reducing the restriction of the space defined by the cabinet 2 on the maximum angle that the door body 3 therein can open.

[0267] In some embodiments of the present application, the refrigerator includes a locking assembly. The locking assembly includes a first mating portion and a second mating portion that cooperate to lock and unlock the door 3 and the cabinet 1. The first mating portion is located on the cabinet 1 near the lower end of the door 3, and the second mating portion is located at the lower end of the door 3 to mate with the first mating portion.

[0268] In some embodiments of the present application, the first mating portion is located on a side of the first hinge member away from the first body side wall. The second mating portion is located on a side of the second hinge member away from the door side wall 33. The second mating portion is used to cooperate with the first mating portion to achieve locking and unlocking of the door body 3 and the box body 1.

[0269] In some embodiments of the present application, the locking process of the door 3 and the box 1 is as follows:

[0270] When the door body 3 is closed from the open state, the door body 3 gradually closes. As the door body 3 rotates to close, the second matching portion gradually approaches the first matching portion.

[0271] When the door 3 is closed to the angle G B0 When the second mating portion contacts the first mating portion, the door body 3 continues to close. The first and second mating portions interact with each other, causing the second mating portion to elastically deform. Under the combined action of the external force and the force acting on the first mating portion, the second mating portion gradually approaches the first mating portion, and the elastic deformation of the second mating portion gradually increases.

[0272] When the door 3 is closed to the angle G B2 , the elastic deformation of the second matching portion reaches the maximum deformation during the closing process of the door body 3.

[0273] When the door 3 closes and reaches angle G B2 Then, the second mating portion continues to move in the closing direction, and the elastic energy stored in the elastic deformation of the second mating portion is released, and the second mating portion recovers to the relaxed state, and drives the door body 3 to automatically close in place. When the door body 3 reaches the closed state, the second mating portion locks with the first mating portion, and the door body 3 and the box body 1 are locked.

[0274] Above, G B0 >G B2 .

[0275] From the above, it can be seen that the door body 3 is formed by the angle G B0 Close to angle G B2 During the process, the elastic deformation of the second matching portion continues to increase.

[0276] When the door 3 is closed to the angle G B2 When the elastic deformation of the second matching portion reaches the maximum deformation during the closing process of the door body 3.

[0277] The door body 3 is formed by the angle G B2 In the process of reaching the closed state, the elastic force of the second matching portion is released and the door body 3 is automatically closed.

[0278] That is, under the structural setting of the first matching part and the second matching part, the door body 3 is B2 In the process of closing, the door 3 has the characteristic of automatic closing. Under the setting of the locking assembly, the door 3 can automatically close in place to make the door 3 and the box body 1 seal and avoid cold leakage.

[0279] In some embodiments of the present application, the unlocking process of the door 3 and the box 1 is as follows:

[0280] When the door body 3 is opened from the closed state (or when the door body 3 is opened from the angle G0), the door body 3 gradually opens. As the door body 3 rotates to open, the second matching portion interacts with the first matching portion, and the second matching portion is elastically deformed.

[0281] As the door body 3 continues to open, the elastic deformation of the second matching part gradually increases; in the process of continuous elastic deformation of the second matching part, a large external force needs to be applied to make the door body continue to open, so that the first matching part and the second matching part are continuously separated.

[0282] When the door 3 is opened to the angle G B1 , the elastic deformation of the second matching portion reaches the maximum deformation during the opening process of the door body 3.

[0283] When the door 3 opens to the angle G B1 Then, the door 3 is separated from the box body 1 by continuing to move in the opening direction, and the elastic energy stored in the elastic deformation of the second matching portion is released, and the second matching portion returns to the relaxed state.

[0284] In some embodiments of the present application, when the door body 3 is closed to the angle G0, the second matching portion is locked with the first matching portion.

[0285] The door body 3 is opened at an angle G0, the first matching portion interacts with the second matching portion, and the second matching portion undergoes elastic deformation;

[0286] When the door is opened to angle G B1 Afterwards, the elastic energy stored in the elastic deformation of the second matching portion is released.

[0287] That is, the door body 3 opens from the angle G0 to the angle G B1 During the process, the deformation amount of the second matching portion undergoing elastic deformation increases continuously. B1 When the second matching portion undergoes elastic deformation, the amount of deformation reaches the maximum amount of deformation during the closing process of the door body 3. B1 During the process of continuing to open, the elastic force of the second matching portion is released.

[0288] In some embodiments of the present application, G B2 =G B1 .

[0289] In some embodiments of the present application, the second engaging portion is located on the side of the second shaft 6 and guide portion 8 away from the door sidewall 33. The second engaging portion is configured as a locking hook. Specifically, the locking hook first extends away from the door sidewall 33, then bends toward the side closer to the door rear wall 32 and the door sidewall 33, with the opening of the locking hook facing the door sidewall 33. The free end of the locking hook is located on the side closer to the door rear wall 32.

[0290] In some embodiments of the present application, the first matching portion is provided on a side of the hinge plate 4 away from the side wall of the first body. The first matching portion is provided as a stopper. A side of the stopper close to the box body 1 has a hooking gap.

[0291] When the door 3 is in the closed state (or G0), the free end of the lock hook is accommodated in the hook gap, the stop portion is located inside the lock hook, and the lock hook on the door 3 hooks the stop portion on the hinge plate 4, thereby locking the door 3 and the cabinet 1, preventing the door 3 from being loosely closed and causing cold air to leak, which would affect the refrigeration / freezing performance of the refrigerator 100. When the door 3 is opened, the lock hook is deformed by the force, overcoming the obstruction of the stop portion and disengaging from the stop portion, thereby unlocking the door 3 and the cabinet 1.

[0292] When the door body 3 is opened from the closed state (or G0), under the action of external force, the door body 3 gradually opens. As the door body 3 rotates to open, the free end of the lock hook interacts with the stopper, and the lock hook is elastically deformed.

[0293] Then, under the action of external force, the door body 3 continues to open, the stopper interacts with the lock hook, the lock hook is elastically deformed, and under the combined action of the external force and the stopper force, the lock hook gradually disengages from the hooking gap (at the same time, the stopper disengages from the lock hook).

[0294] When the door 3 is opened to the angle G B1 When the elastic deformation of the lock hook reaches the maximum deformation during the closing process of the door body 3.

[0295] When the door 3 opens to the angle G B1 Then continue to open, the elastic energy stored in the elastic deformation of the lock hook is gradually released, the lock hook recovers to the relaxed state, and drives the free end of the lock hook to further disengage from the hook gap, the lock hook is separated from the stop portion, and the door body 3 is separated from the box body 1.

[0296] In some embodiments of the present application, the first directional displacement occurs during the process in which the first matching portion and the second matching portion are unlocked from the locked state and the elastic deformation of the second matching portion continues to increase. Second direction displacement In the above, during the unlocking of the first matching part and the second matching part and the continuous increase in the elastic deformation of the second matching part, the door body 3 has a tendency to move inward and backward, which accelerates the separation of the first matching part and the second matching part, reduces the force of the first matching part on the second matching part, reduces the elastic deformation of the second matching part, facilitates the unlocking of the first matching part and the second matching part, and is beneficial to the unlocking of the door body and the box body.

[0297] In some embodiments of the present application, during the process of unlocking the first and second mating parts from the locked state and the elastic deformation of the second mating part continuously increasing, the center point I of the axis moves toward the side close to the plane where the side wall of the second body and the access opening are located. As described above, during the process of unlocking the first and second mating parts and the elastic deformation of the second mating part continuously increasing, the door body 3 has a tendency to move inward and backward, which accelerates the separation of the first and second mating parts, reduces the force exerted by the first mating part on the second mating part, reduces the elastic deformation of the second mating part, facilitates the unlocking of the first and second mating parts, and facilitates the unlocking of the door body and the box body.

[0298] It should be noted that the process in which the first fitting portion and the second fitting portion are unlocked from the locked state and the elastic deformation of the second fitting portion continuously increases includes the moment when the elastic deformation of the second fitting portion reaches the maximum.

[0299] In some embodiments of the present application, the door body 3 is opened by being locked by the first mating part and the second mating part. As the door body 3 is opened, the second mating part undergoes elastic deformation. In the process of gradually releasing the elastic energy stored in the elastic deformation of the second mating part, the second axis 6 moves relative to the guide part 7 to the position where the distance between it and the take-and-put port in the plane is the largest.

[0300] It should be noted that the process of gradually releasing the elastic energy stored in the elastic deformation of the second fitting portion includes the moment when the elastic deformation of the second fitting portion reaches the maximum.

[0301] As described above, during the unlocking process of the first and second fitting parts, after the elastic deformation of the second fitting part reaches the maximum, the interaction force between the first and second fitting parts decreases rapidly, and the external force required also decreases rapidly. However, the external force applied by the user cannot be reduced rapidly or the inertial force of the door body opening still exists, resulting in a rapid increase in the relative movement speed of the first and second fitting parts; at this time, the second shaft 6 moves relative to the guide part 7 to the position where the distance between it and the take-in and put-out opening is the largest in the plane. Based on the fact that the guide trajectory line S is raised toward the side away from the plane where the take-in and put-out opening is located, the second shaft 6 has resistance to moving relative to the guide part 7 toward the side close to the first body side wall or away from the first body side wall. The second shaft 6 located on the guide part 7 at the point where the distance from the take-in and put-out opening is the largest is in a relatively stable state relative to the guide part 7, and the movement of the door body 3 relative to the box body 1 is in a stable state, so that the unlocking process of the first and second fitting parts is more stable and smooth.

[0302] In some embodiments of the present application, when the door body 3 is closed to the angle G0, the second matching portion is locked with the first matching portion.

[0303] The door body 3 is opened at the angle G0, the first matching portion interacts with the second matching portion, and the second matching portion is elastically deformed.

[0304] When the door 3 is opened to the angle G B1 Afterwards, the elastic energy stored in the elastic deformation of the second matching portion is released.

[0305] When the door body 3 is opened from the angle G0 to the angle G1, the second shaft 6 moves relative to the guide portion 7 toward the side wall of the first body and away from the access opening;

[0306] When the door body 3 opens from the angle G1 to the angle G2, the second shaft 6 moves relative to the guide portion 7 toward the side close to the first body side wall and the plane where the take-in / put-out opening is located; wherein, G0<G B1 <G1<G2, or G0<G1<G B1 <G2;

[0307] Among them, G1 and G B1 The absolute value of the difference is recorded as |G1-G B1 |, 0°≤|G1-G B1 |≤3°. When the above door body 3 is opened at an angle of G1, the second center axis P is located at the first guide point P1 on the guide trajectory line S at the maximum distance from the plane where the pick-up and release port is located. Correspondingly, the second axis 6 is located on the guide portion 7 at the maximum distance from the plane where the pick-up and release port is located. Because the guide trajectory line S is convex toward the side away from the plane where the pick-up and release port is located, the second axis 6 has resistance to moving relative to the guide portion 7 toward the side close to the first body side wall or away from the first body side wall. The second axis 6 located on the guide portion 7 at the maximum distance from the plane where the pick-up and release port is located is in a relatively stable state relative to the guide portion 7, and the movement of the door body 3 relative to the box body 1 is in a stable state.

[0308] When the door 3 is opened and the first and second mating parts are unlocked, a relatively large external force must be applied first to cause the second mating part to elastically deform under the action of the first mating part. After the elastic deformation of the second mating part reaches its maximum, the interaction force between the first and second mating parts decreases rapidly, and the external force required also decreases rapidly. However, if the external force applied by the user fails to decrease rapidly or the inertial force of the door 3 opening still exists, the relative movement speed of the first and second mating parts increases rapidly, making the unlocking process of the first and second mating parts unstable, resulting in unstable opening of the door 3.

[0309] Above 0°≤|G1-G B1 |≤3° is set so that when the first mating portion and the second mating portion are unlocked, the second shaft 6 maintains stable movement relative to the guide portion 7, so that the unlocking process of the first mating portion and the second mating portion is more stable and smooth.

[0310] |G1-G B1 |>3°, the maximum deformation angle G of the first mating portion and the second mating portion unlocking B1, and the difference between the stable angle G1 of the second shaft 6 relative to the guide part 7 is too large. The unlocking process of the first matching part and the second matching part cannot effectively correspond to the process of the second shaft 6 maintaining stable movement relative to the guide part 7. The cooperation between the second shaft 6 and the guide part 7 cannot stabilize the unlocking process of the first matching part and the second matching part.

[0311] In some embodiments of the present application,

[0312] In some embodiments of the present application, the second guide point P2 is the second limit guide point P2'. When , the second center axis P is located at the position of the guide trajectory line S where the distance from the side wall of the first body is the largest (the second limit guide point P2` / the second guide point P2).

[0313] In some embodiments of the present application, the second limit guide point P2' is located on the side of the second guide point P2 away from the side wall of the first body and close to the plane where the take-out opening is located. When the second central axis P is relative to the guide track line S, there is a certain distance between it and the second limit guide point P2'. When the guide portion 7 is set as a guide groove, the second shaft 6 is located at a position where the guide portion 7 is away from the side wall of the first body, and there is a gap between the second shaft 6 and the end of the guide portion 7 away from the side wall of the first body. When the door 3 is opened, a gap exists between the second shaft 6 and the end of the guide groove away from the first side wall. The above arrangement prevents the second shaft 6 from colliding with the end of the guide portion 7 away from the first side wall during the door 3 opening process, thereby avoiding the impact between the second shaft 6 and the end of the guide portion 7 away from the first side wall, thereby preventing the second shaft 6 from being damaged.
