Description

Technical Field

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

[0002] For built-in refrigerators, the refrigerator is placed in a cabinet. Due to the limitation of the cabinet space, in order to increase the utilization rate of the refrigerator to the cabinet space, it is required that the corner of the door body should extend beyond the cabinet body as little as possible or not extend beyond the cabinet body during the door opening process. For this reason, a hinge assembly with two shafts and two grooves is now provided to make the door body move to the side away from the cabinet during the opening process to limit the size of the corner of the door body extending beyond the cabinet body, so as to increase the utilization rate of the refrigerator to the cabinet space.

[0003] After the refrigerator door is opened, its center of gravity shifts. On the one hand, the shift in center of gravity will cause the door to close automatically, making it impossible for the door to remain in an open state, causing inconvenience to the user in taking and placing items. On the other hand, the double groove setting in the hinge assembly in which the two axes and the two grooves cooperate often has trajectory change points. The shift in center of gravity will cause the axis and the groove to 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 G5, the second axis moves to the inflection point relative to the guide part, the first axis is located at the end of the guide part close to the door side wall, the movement stability of the first axis relative to the guide part and the second axis relative to the guide part is high, and the rotation of the door body relative to the box body is more stable when it is opened to G5>90°, and the door body can also be maintained in the state of G5>90°.

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

[0006] The box body defines a plurality of accommodating chambers with access openings; the box body has a first body side wall and a second body side wall that are arranged opposite to each other;

[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 is provided on the box body and close to the side wall of the first body; the first hinge comprises:

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

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

[0014] The second hinge member is arranged 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 first extends from an end thereof 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 opening is located, and then extends to a side close to the first body side wall and the plane where the access opening is located;

[0018] When the door body is opened to G5, the first axis is located at the end of the guide portion close to the door side wall, and the second axis moves relative to the guide portion to a position where the distance between it and the plane where the access port is located is the largest, wherein G5>90°.

[0019] In the above technical solution, when the door body is opened to G5, the second axis moves to the inflection point relative to the guide part, and the first axis is located at the end of the guide part close to the door side wall. 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 G5>90°, the rotation relative to the box body is more stable, and the door body can also be maintained in the state of G5>90°.

[0020] 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 a side away from the first body side wall and the plane where the access port is located, and the first axis moves relative to the guide portion toward a side close to the door side wall and the door front wall; wherein, G4<G5.

[0021] 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-to-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.

[0022] In some embodiments, the guide portion first 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.

[0023] In the above technical solution, the extension trend of the guide portion is defined, and the extension trend of the guide portion is divided into two sections. The extension trend of the trajectory is simple, thereby improving the movement smoothness of the first axis relative to the guide portion.

[0024] In some embodiments, when the door body is opened to G4=90°, the first axis moves relative to the guide portion to a position where the distance between the first axis and the front wall of the door is the largest, and the second axis is located at the end of the guide portion close to the first body side wall.

[0025] 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 portion, and the second axis is located at the end of the guide portion close to the side wall of the first body. The movement stability of the first axis relative to the guide portion and the second axis relative to the guide portion 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°.

[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 second shaft relative to the guide portion is recorded as a guide trajectory line S, and the guide trajectory line S protrudes toward a side away from the plane where the access port is located;

[0029] The guide trajectory line S is an arc;

[0030] During the door opening process, when the door opening angle is G1', the distance between the central axis of the second shaft and the side wall of the first body is the smallest; at this time, the central axis of the second shaft is located at the first extreme guide point P1' of the guide trajectory line S;

[0031] When the door body is opened at an angle of G2', the distance between the central axis of the second shaft and the side wall of the first body is the largest; at this time, the central axis of the second shaft is located at the second extreme guide point P2' of the guide trajectory line S;

[0032] Among them, 20°≤∠P1`OP2`≤30°.

[0033] In the above technical solution, when ∠P1`OP2`<20°, ∠P1`OP2` is too small, the length of the guide trajectory is too small, the length of the guide part is too small, and the number of relative frictions when the second shaft moves relative to the guide part is large, which increases the wear of the second shaft and the guide part and reduces the life of the hinge assembly.

[0034] When 30°<∠P1`OP2`, ∠P1`OP2` is too large, the length of the guide trajectory is too large, the length of the guide part is too large, and the guide part occupies a large space of the hinge plate, resulting in reduced strength of the hinge plate and the guide part, thereby reducing the service life of the hinge assembly.

[0035] When the setting of 20°≤∠P1`OP2`≤30° limits the length of the guide trajectory (guide part), on the one hand, it reduces the number of relative friction times of the second shaft moving relative to the guide part to reduce the wear of the second shaft and the guide part; on the other hand, it reduces the space occupied by the guide part on the hinge plate, avoids the reduction of the strength of the hinge plate, and ensures the service life of the hinge assembly.

[0036] In some embodiments, the point where the distance between the guide track line S and the plane where the access port is located is the largest is recorded as the first guide point P1;

[0037] Among them, 12°≤∠P1`OP1≤20°.

[0038] In the above technical solution,

[0039] 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;

[0040] 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;

[0041] In the plane projection parallel to the top wall of the box body, along the 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.

[0042] In the above technical solution, when 3mm<|PK|1, |PK|1 is too large, and in the direction perpendicular to the front wall of the door, the distance between the second center axis P and the first guide point K on the guide trajectory line which is the longest distance from the door side wall is too large; in the process of the door body moving 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, and at this time, the stability of the door body moving relative to the box body is poor.

[0043] In the present application, with the setting of 0mm≤|PK|1≤3mm, in the direction perpendicular to the front wall of the door, the second axis is close to the first guide point K on the guide trajectory line which is at the largest distance from the door side wall; in the process of the door body moving 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 door body moving relative to the box body.

[0044] In some embodiments, 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;

[0045] In a plane projection parallel to the top wall of the box body, 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.

[0046] In the above technical solution, when 5mm<|PH|2, |PH|2 is too large, and in the direction perpendicular to the door side wall, the distance between the second axis and the third guide point H on the guide trajectory line which is the longest distance from the door front 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, and at this time, the stability of the movement of the door body relative to the box body is poor.

[0047] In the present application, with the setting of 0mm≤|PH|2≤5mm, in the direction perpendicular to the door side wall, the second axis is close to the third guide point H on the guide trajectory line which is at the largest distance from the door front wall; 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 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 movement of the door body relative to the box body.

[0049] The box body defines a plurality of accommodating chambers with access openings; the box body has a first body side wall and a second body side wall that are arranged opposite to each other;

[0051] A door front wall, which is away from the box body when the door body is closed;

[0052] 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;

[0053] 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:

[0054] A first hinge is provided on the box body and close to the side wall of the first body; the first hinge comprises:

[0057] The second hinge member is arranged on the door body; the second hinge member comprises:

[0058] a second shaft, which cooperates with the guide portion;

[0059] a guide portion, which cooperates with the first shaft;

[0060] During the process of the door body opening from G2 to G3, the second shaft moves relative to the guide portion toward a side close to the side wall of the first body and away from the plane where the access opening is located;

[0061] During the process of the door body opening from G3 to G4, the second shaft moves relative to the guide portion toward a side close to the plane where the first body side wall and the access opening are located;

[0062] When the door body is opened to G5, the first axis moves relative to the guide portion to its end close to the door side wall, and the second axis moves relative to the guide portion to the position of the second axis relative to the guide portion when the door body is opened to G3; wherein, G3<G4=90°<G5.

[0092] Among them, see Figure 1 The direction from the bottom wall of the box 1 to the top wall is the height direction. The direction extending from the intersection line of the top wall and the rear wall of the box 1 is the width direction. The direction orthogonal to both the height direction and the width direction is the front-rear direction.

[0093] In some embodiments of the present application, the box body 1 defines a plurality of accommodating chambers. A take-in and put-out opening for taking and putting items is formed at the front end of the accommodating chamber, and a user can place food into the accommodating chamber or take food out of the accommodating chamber through the take-in and put-out opening. A rotatable door body 3 is provided on the box body 1 to open or close the take-in and put-out opening of the accommodating chamber. For example, the door body 3 is rotatably connected to the box body 1 through a hinge assembly located at an upper portion and a hinge assembly located at a lower portion. Among them, in the front-to-back direction, the take-in and put-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 and put-out opening (the rear wall of the box body 1).

[0098] 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.

[0099] It should be noted that when the door front wall 31 and the door side wall 33 are both flat wall surfaces, the intersection line of the plane where the door front wall 31 is located and the plane where the door side wall 33 is located is the first side edge W. When the rounded transition is set at the intersection of the door front wall 31 and the door side 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 extending along the height direction of the door body 3 on the curved surface represents the first side edge W. Similarly, the rounded transition is set at the intersection of the door rear wall 32 and the door side wall 33, and the second side edge N can be represented by the intersection line of the planes where the door rear wall 32 and the door side wall 33 are located, or by a straight line close to the intersection line and parallel to the intersection line.

[0100] In some embodiments of the present application, a door seal is provided on the door rear wall 32 of the door body 3. When the door body 3 closes the access opening, the door seal surrounds the access opening to effectively seal the access opening. When the door body 3 is closed, the door seal fits with the front end surface of the box body 1 to effectively seal the connection between the door body 3 and the box body 1, thereby ensuring that the door body 3 seals the access opening to prevent cold air from leaking out.

The first shaft 5 is located on the side of the guide portion 7 away from the side wall of the first body. The above arrangement enables the first shaft 5 and the guide portion 7 to be arranged along the width direction of the box body 1, reducing the space occupied along the front and rear direction of the box body 1, making the structure of the first hinge more compact.

[0114] 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 at an end close to the first hinge member. The second shaft 6 is located on a side of the guide portion 8 close to the door front wall 31.

[0115] 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 the door body 3 rotating 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 port.

[0116] The center axis of the first shaft 5 is recorded as the first center axis Q. The center axis of the second shaft 6 is recorded as the second center axis P. When the door body 3 is opened, the trajectory line of the second center axis P moving relative to the guide part 7 is recorded as the guide trajectory line S.

[0117] In some embodiments of the present application, the guide trajectory line S is a curve. The curved guide trajectory line S protrudes toward the side away from the plane where the access port is located. That is, the guide trajectory line S first extends from the end away from the first body side wall to the side close to the first body side wall and away from the plane where the access port is located, and then extends to the side close to the first body side wall and the plane where the access port is located. The extension trend of the above guide trajectory line S is divided into two sections, and its trajectory extension trend is simple, which improves the movement smoothness of the second axis relative to the guide portion.

[0118] In some embodiments of the present application, the guide track line S is an arc, so that the movement of the second shaft 6 relative to the guide portion 7 is smoother.

[0119] 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 access port is located.

[0120] In some embodiments of the present application, the guide groove is an arc groove.

[0121] 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 arranged opposite to the guide groove bottom. The second shaft 65 penetrates into the guide groove through the guide groove opening. The circumferential side wall of the second shaft 65 cooperates with the circumferential guide groove wall of the guide groove to guide the second shaft 65 when the second shaft 65 moves relative to the guide groove. The guide groove is arranged as above to guide the second shaft 6 through its circumferential guide groove wall, and its relative movement is more stable.

[0122] In some embodiments of the present application, the guide groove includes a guide notch provided on the hinge plate 4. The second shaft 6 passes through the guide notch, and the circumferential side wall of the second shaft 6 cooperates with the hinge plate 4 surrounding the guide notch to guide the second shaft 6 when the second shaft 65 moves relative to the guide groove. The above arrangement can achieve the purpose of the guide groove guiding the second shaft 6, and is easy to process.

[0123] 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 release port is located. The radius of the arc-shaped guide track line S is recorded as the guide radius R.

[0124] In some embodiments of the present application, 8mm≤R≤12mm.

[0125] 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 fast change in the movement speed of the second shaft 6 relative to the guide portion 7 .

[0126] 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 axis 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 the guide part 7, thereby reducing the service life of the hinge assembly.

[0127] When 8 mm ≤ 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 .

[0128] 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.

[0129] The above setting of 8mm≤R≤12mm makes the movement of the second shaft 6 relative to the guide portion 7 more stable, so as to improve the stability of the movement of the door body 3 relative to the box body 1. On the other hand, the area range occupied by the guide portion 7 on the hinge plate 4 is limited to ensure the strength of the hinge plate 4 and the guide portion 7, and effectively ensure the service life of the hinge assembly.

[0130] 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 access port is located and the side wall of the first body.

[0131] 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.

[0132] 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 limit guide point P1' of the guide track line S.

[0133] When the door 3 opens at an angle When the distance between the second central axis P and the side wall of the first body is the largest, the second central axis P is located at the second limit guide point P2' of the guide track line S.

[0134] 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.

[0135] In some embodiments of the present application, in the projection of the plane where the top wall of the box body 1 is located, the first guide point P1, the first limit guide point P1', and the second limit guide point P2' are all located on the side of the first central axis Q away from the plane where the access port is located. That is, the track segment of the guide track line S extending from the first limit guide point P1' through the first guide point P1 to the second limit guide point P2' is located on the side of the first central axis Q away from the plane where the access port is located.

[0136] In some embodiments of the present application, |QP1`|1≤|QP1|1, |QP2`|1≤|QP1|1. In which, |QP1|1=|QP1`|1 and |QP1|1=|QP2`|1 do not hold simultaneously.

[0137] In some embodiments of the present application, 0mm≤|QP1|1≤4mm.

[0138] When 4mm<|QP1|1, when the second axis 6 moves 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, 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 excessive 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, 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 failing to effectively reduce the restriction on the movement of the door body 3 by the space defined by the cabinet 2.

[0139] 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.

[0140] In some embodiments of the present application, 0mm≤|QP1`|1≤2mm.

[0141] 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 access port is located is too large, resulting in excessive displacement of the door body 3 relative to the box body 1 in the direction perpendicular to the plane where the access port is located, 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 failing to effectively reduce the restriction on the movement of the door body 3 by the space defined by the cabinet 2.

[0142] 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 smallest. In the direction perpendicular to the plane where the access 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 access 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.

[0143] In some embodiments of the present application, 0mm≤|QP2`|1≤3mm.

[0144] 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 access port is located is too large, resulting in excessive displacement of the door body 3 relative to the box body 1 in the direction perpendicular to the plane where the access port is located, 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 failing to effectively reduce the restriction on the movement of the door body 3 by the space defined by the cabinet 2.

[0145] 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 access 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 access 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.

[0146] In the above, the limitations of 0mm≤|QP1|1≤4mm, 0mm≤|QP1`|1≤2mm, and 0mm≤|QP2`|1≤3mm jointly define the overall trend of the guide trajectory line S, so that during the opening 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 opening process of 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.

[0147] In some embodiments of the present application, 20°≤∠P1`OP2`≤30°.

[0148] 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.

[0149] 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.

[0150] When 20°≤∠P1`OP2`, the length of the guide trajectory is limited within a reasonable range, the number of relative frictions of the second shaft 6 relative to the guide portion 7 is limited, reducing the wear of the second shaft 6 and the guide portion 7 and ensuring the life of the hinge assembly.

[0151] When ∠P1`OP2`≤30°, the length of the guide track line is limited within 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.

[0152] When the setting of 20°≤∠P1`OP2`≤30° limits the length of the guide trajectory (guide portion 7), on the one hand, the number of relative friction times of the second shaft 6 relative to the guide portion 7 is reduced to reduce the wear of the second shaft 6 and the guide portion 7; on the other hand, the space occupied by the guide portion 7 on the hinge plate 4 is reduced, thereby avoiding a reduction in the strength of the hinge plate 4 and ensuring the service life of the hinge assembly.

[0153] In some embodiments of the present application, 12°≤∠P1`OP1≤20°.

[0154] The movement distance of the second shaft 6 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.

[0155] When ∠P1`OP1<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, the first stroke of the door body 3 relative to the box body 1 along the width direction and the front-to-back direction is too small, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0156] 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 that 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 excessive displacement of the door body 3 in at least one section of the movement process relative to the box body 1 in the direction perpendicular to the plane where the pick-up and release port is located, resulting in an imbalance in the movement of the door body 3 relative to the box body 1 along the width direction and the movement along the front-to-back direction, and failing to effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0157] 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 along 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 defined by the cabinet 2 on the movement of the door body 3.

[0158] 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.

[0159] In the present application, the setting of 12°≤∠P1`OP1≤20° enables the second axis 6 to move to the guide portion 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 defined by the cabinet 2 on the movement of the door body 3.

[0160] In some embodiments of the present application, 7°≤∠P2`OP1≤11°.

[0161] 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 travel.

[0162] When ∠P2`OP1<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 extreme guide point P2` is too small, the second stroke of the door body 3 relative to the box body 1 along the width direction and the front-to-back direction is too small, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0163] 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 that 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 excessive displacement of the door body 3 in at least one section of the movement process relative to the box body 1 in the direction perpendicular to the plane where the pick-up and release port is located, resulting in an imbalance in the movement of the door body 3 relative to the box body 1 along the width direction and the movement along the front-to-back direction, and failing to effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0164] 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 along 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 defined by the cabinet 2 on the movement of the door body 3.

[0165] 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.

[0166] In the present 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.

[0167] In some embodiments of the present application, 1.6≤∠P1`OP1:∠P2`OP1≤2.

[0168] When ∠P1`OP1:∠P2`OP1<1.6, ∠P1`OP1:∠P2`OP1 is too small, the first stroke is too small, the movement amount of the door body 3 relative to the box body 1 in the width direction and the movement amount in the front-back direction are appropriate, and the first stroke 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. In addition, the ratio of the first stroke to the second stroke is too small, and the distribution of the first stroke and the second stroke of the door body 3 relative to the box body 1 when moving is unbalanced, and cannot meet the displacement requirements of the door body 3 at each stage of opening.

[0169] 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 where the access port is located is too large, resulting in excessive displacement of the door body 3 relative to the box body 1 in at least one section of the direction perpendicular to the plane where the access port is located, 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, which 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 large, and the distribution of the first stroke and the second stroke of the door body 3 relative to the box body 1 when moving is unbalanced, which cannot meet the displacement requirements of the door body 3 at each stage of opening.

[0170] When 1.6≤∠P1`OP1:∠P2`OP1, the first stroke meets the movement requirements of the door body 3, and the first stroke with appropriate movement amount of the door body 3 in the width direction and the movement amount in the front-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 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 a suitable range to control the relative amount of the first stroke and the second stroke of the door body 3 relative to the box body 1 when moving, which can meet the displacement requirements of the door body 3 at each stage of opening.

[0171] When ∠P1`OP1≤20°, during the movement of the first stroke, in the direction perpendicular to the plane where the access port is located, the second axis 6 approaches the first axis 5, effectively controlling 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, which can 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 limited to a suitable range to control the relative amount of the first stroke to the second stroke of the door body 3 relative to the box body 1 during movement, which can meet the displacement requirements of the door body 3 at each stage of opening.

[0172] In the present application, the setting of 1.6≤∠P1`OP1:∠P2`OP1≤2 enables the movement of the door body 3 relative to the box body 1 in the width direction and the front-to-back direction in the direction perpendicular to the plane where the access port is located to be appropriate during the movement of the first stroke, and the stroke appropriately meets the movement requirements of the door body 3, so as to more efficiently reduce the movement of the door body 3 in the space defined by the cabinet 2. In addition, the ratio of the first stroke to the second stroke is limited to a suitable range to control the relative amount of the first stroke and the second stroke of the door body 3 relative to the box body 1 during movement, which can meet the displacement requirements of the door body 3 at each stage of opening.

[0173] 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 opening is located, the distance between the first central axis Q and the guide circle center O is recorded as |QO|1. 3≤|QO|1:|QP1|1.

[0174] 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 portion 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 excessive 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, 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 failing to effectively reduce the restriction on the movement of the door body 3 by the space defined by the cabinet 2.

[0175] 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.

[0176] 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.

[0177] In some embodiments of the present application, the guide trajectory F includes a first guide segment, and the first guide segment extends from an end thereof 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 .

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

[0179] In some embodiments of the present application, the guide trajectory line F includes a second guide segment, and the second guide segment 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 .

[0180] 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 .

[0181] In some embodiments of the present application, the guide track line F includes a first guide segment and a second guide segment connected to each other. The guide track line F extends from one end of the first guide segment away from the second guide segment to a side close to the door side wall 33 and away from the door front wall 31 to H, and then extends from H to a side close to the door side wall 33 and the door front wall 31. The extension trend of the track of the central axis of the first axis guided by the guide portion is defined, and the extension trend of the guide track line is divided into two sections, and the extension trend of the track is simple, thereby improving the smoothness of the movement of the first axis relative to the guide portion.

[0182] In some embodiments of the present application, the guide track line F is in a curved shape. The curved guide track line F protrudes toward the side away from the door front wall 31. The guide track line F includes a first guide section and a second guide section connected to an end of the first guide section close to the door side wall 33. Specifically, the guide track line F extends from an end thereof 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, and then extends to a side close to the door side wall 33 and the door front wall 31.

[0183] In some embodiments of the present application, the distance between one end of the guide trajectory line F away from the door side wall 33 and the door front wall 31 is smaller than the distance between one end of the guide trajectory line F close to the door side wall 33 and the door front wall 31 .

[0184] In some embodiments of the present application, the point where the guide trajectory line F is far away from the door side wall 33 and has the shortest distance from the door front wall 31 is recorded as the first guide point K. The point where the guide trajectory line F is close to the door side wall 33 and has the shortest distance from the door front wall 31 is recorded as the second guide point J. The point where the guide trajectory line F has the longest distance from the door front wall 31 is recorded as the third guide point H.

[0185] Corresponding to the guide portion 8, the point where the distance between the end of the guide portion 8 away from the door side wall 33 and the door front wall 31 is the minimum is recorded as the first guide boundary point K'. The point where the distance between the end of the guide portion 8 close to the door side wall 33 and 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'.

[0186] Among them, 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) for matching 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.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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`, the third guide boundary point H`, and the radius of the first axis 5 can be measured by a measuring tool, and 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.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] In some embodiments of the present application, under the definition 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.

[0195] 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.

[0196] In the case where the door front wall 31 and the door side wall 33 are not arranged perpendicularly, the direction perpendicular to the door front wall 31 only indicates the distance in the direction perpendicular to the door front wall 31, and there is no necessary connection between the direction perpendicular to the door side wall 33 and the parallel relationship. Similarly, the direction perpendicular to the door side wall 33 only indicates the distance in the direction perpendicular to the door side wall 33, and there is no necessary connection between the direction perpendicular to the door front wall 31 and the parallel relationship.

[0197] Reference Figure 6 In the 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 the direction perpendicular to the door side wall 33 is recorded as |PH|2. Among them, 0mm≤|PH|2≤5mm.

[0198] When 5mm<|PH|2, |PH|2 is too large, and in the direction perpendicular to the door side wall 33, the distance between the second axis 6 and the third guide point H on the guide trajectory line which is the farthest from the door front wall 31 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.

[0199] In the present application, with the setting of 0mm≤|PH|2≤5mm, in the direction perpendicular to the door side wall 33, the second axis 6 is close to the third guide point H on the guide trajectory line which is at the largest distance from the door front wall 31; 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, in the direction perpendicular to the door side wall 33, the second center axis 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.

[0200] 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 along the direction perpendicular to the door front wall 31 is recorded as |PK|1. Among them, 0mm≤|PK|1≤3mm.

[0201] When 3mm<|PK|1, |PK|1 is too large, and in the direction perpendicular to the door front wall 31, the distance between the second center axis P and the first guide point K on the guide trajectory line which is the farthest away from the door side wall 33 is too large; in the process of the movement of the door body 3 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 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.

[0202] In the present application, with the setting of 0mm≤|PK|1≤3mm, 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 at the largest distance from the door side wall 33; in the process of the movement of the door body 3 relative to the box body 1, when the door body 3 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 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.

[0203] 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 .

[0204] 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 track line 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 track line S, so that the door body 3 can move a 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 is effectively opened.

[0205] In some embodiments of the present application, during the opening 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 a point that maintains dynamic changes relative to the box body 1 throughout the entire process.

[0206] 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 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 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.

[0207] 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 keeps changing, the position of the center point I of the axis keeps changing relative to the box body 1, and the rotation center axis of the door body 3 relative to the box body 1 keeps changing.

[0208] The guide track line F includes a second guide point J close to one end of the door side wall 33 and a first guide point K far from one end of the door side wall 33. The guide track line F first extends from the first guide point K to a side close to the door side wall 33 and far from the door front wall 31 to a third guide point H, and then extends from the third guide point H to a side close to the door side wall 33 and the door front wall 31 to the second guide point J.

[0209] In some embodiments of the present application, the guide trajectory line F is a smooth convex curve, so that the movement of the first shaft 5 relative to the guide portion 8 is smoother.

[0210] 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 distance inward (toward the direction of the second body side wall) 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.

[0211] The movement of the door body 3 relative to the box body 1 is equivalent to the relative movement of the two in the plane where the top wall of the box body 1 is located (or in the plane parallel to the top wall of the box body 1); that is, the movement of the door body 3 relative to the box body 1 is a relative movement in a two-dimensional plane. In the plane where the top wall of the box body 1 is located, the movement of the guide portion 8 on the door body 3 relative to the first shaft 5 provided on the box body 1 (or the movement of the second shaft 6 on the door body 3 relative to the guide portion 7 provided on the box body 1) is equivalent to the movement of the door body 3 relative to the hinge plate 4, and is also equivalent to the movement of the door body 3 relative to the box body 1.

[0212] 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.

[0213] 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 is opened.

[0214] During the movement of the door body 3 relative to the box body 1, the door body 3 has a translational movement while rotating. The translational movement of the door body 3 is decomposed into a first direction movement perpendicular to the first body side wall direction (along the A axis) and a second direction movement perpendicular to the plane direction where the access port is located (along the B axis). The movement amount in the first direction perpendicular to the first body side wall direction (along the A axis) is recorded as the first direction displacement The first direction displacement When , it has an inward displacement; displacement in the first direction When , it has an outward displacement. Among them, the first direction displacement The module is

[0215] The displacement in the second direction perpendicular to the plane of the access port (along the B axis) is recorded as the displacement in the second direction. 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

[0216] In some embodiments of the present application, the opening angle of the door body 3 is When the door is in the closed state, the first axis 5 is located at the end of the guide part 8 away from the door side wall 33, and the second axis 6 is located at the end of the guide part 7 close to the first body side wall. The above defines the position of the first axis relative to the guide part and the position of the second axis relative to the guide part when the door is closed, so as to define the movement trend of the first axis relative to the guide part and the second axis relative to the guide part in the first stage of the door opening, thereby defining the translation trend of the door body relative to the cabinet in the first stage of the door opening, so as to avoid interference between the door body and the cabinet, and avoid or reduce the door body squeezing the door seal.

[0217] In some embodiments of the present application, Figure 7 , Figure 8 , Figure 13-Figure 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.

At this time, the second central axis P is located at the position on the guide trajectory line S where the distance from the plane where the access port is located is the largest.

The first guide position K1 is located on the side of the starting guide position K0 away from the first body 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 body side wall and close to the plane where the access port is located.

[0228] Door body 3 Open to During the process, the guide track line F passes through the first central axis Q and moves relative to the first central axis Q (box body 1 or hinge plate 4).

Open to During the process, the first guide point K moves to a side away from the first body side wall and the plane where the pick-up and release opening is located, and the second guide point J moves to a side away from the first body side wall and close to the plane where the pick-up and release opening is located.

[0231] The opening angle of door body 3 is When , the center point I of the axis is located at the first midpoint I1 relative to the box body 1.

[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 first body side wall. 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.

[0233] 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, thereby preventing the first side edge W from 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 opening angle of the door body 3 therein, thereby making the door body 3 of the refrigerator 100 placed in the cabinet 2 open to a larger angle, making it more convenient for users to take and put items.

[0234] 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 pick-up and release opening is located.

[0236] 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 first body side wall and the access opening are located. Open to During the process, the center point I of the axis moves relative to the box body 1 to the side away from the plane where the side wall of the first body and the access opening are located.

[0239] In some embodiments of the present application, the starting guide point P0 is the first limit guide point P1'. When , the second center axis P is located at the position of the guide trajectory line S where the distance from the first body side wall is the smallest (the first limit guide point P1` / the starting guide point P0).

[0240] In some embodiments of the present application, the starting guide point P0 is located on the side of the first limit guide point P1' away from the plane where the first body side wall and the access opening are located.

When the second shaft 6 is in contact with the end wall of the guide groove close to the first body side wall, there is a gap. When continuing to move in the closing direction, the second shaft 6 can continue to move relative to the guide portion 7 (guide groove) toward the direction close to the side wall of the first body, so that the door body 3 can continue to close.

There is a gap between the second axis 6 and the end of the guide part 7 (guide groove) close to the first body side wall, so that the door body 3 can continue to move in the closing direction from the closed state, so as to ensure that the door body 3 is prevented from generating an impact between the second axis 6 and the end of the guide part 7 close to the first body side wall when the door body 3 is thrown toward the box body 1 with force.

When the door body 3 is in a closed state relative to the box body 1 , it is at a negative angle, and the door body 3 squeezes the door seal to ensure the sealing between the door body 3 and the box body 1 .

Open to During the process, the center point I of the axis moves relative to the box body 1 to the side away from the side wall of the first body and close to the plane where the taking and placing opening is located.

[0267] 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 composed 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 opening angle of the door body 3 therein, so as to facilitate the door body 3 to be opened to a larger angle within the space defined by the cabinet 2.

[0269] In some embodiments of the present application, the refrigerator includes a locking assembly. The locking assembly includes a first matching portion and a second matching portion that match each other, and the first matching portion and the second matching portion match each other to achieve locking and unlocking of the door body 3 and the box body 1. The first matching portion is arranged on the box body 1 near the lower end of the door body 3, and the second matching portion is arranged at the lower end of the door body 3 to match with the first matching portion.

[0270] In some embodiments of the present application, the first matching portion is located on a side of the first hinge away from the first body side wall. The second matching portion is located on a side of the second hinge away from the door side wall 33. The second matching portion is used to match the first matching portion to achieve locking and unlocking of the door body 3 and the box body 1.

[0271] In some embodiments of the present application, the locking process of the door body 3 and the box body 1 is as follows:

[0272] 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.

[0273] When the door body 3 is closed to the angle G B0 When the second matching part contacts the first matching part, the door body 3 continues to close, the first matching part and the second matching part interact with each other, and the second matching part undergoes elastic deformation. Under the combined action of the external force and the action force of the first matching part, the second matching part gradually approaches the first matching part, and the elastic deformation of the second matching part gradually increases.

[0274] When the door body 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.

[0275] When the door 3 closes to the angle G B2 Then, the second matching part continues to move in the closing direction, and the elastic energy stored in the elastic deformation of the second matching part is released, and the second matching part 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 matching part is locked with the first matching part, and the door body 3 and the box body 1 are locked.

[0276] Above, G B0 >G B2 .

[0277] In summary, 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 increases continuously.

[0278] When the door body 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.

[0279] The door body 3 is formed by an angle G B2 During 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.

[0280] That is, under the structural setting of the first matching part and the second matching part, the door body 3 is at the angle G B2 In the process of closing the door 3, the door 3 has the characteristic of automatically closing. Under the setting of the locking assembly, the door 3 can be automatically closed in place so that the door 3 and the box body 1 are sealed to avoid cold leakage.

[0281] In some embodiments of the present application, the unlocking process of the door body 3 and the box body 1 is as follows:

[0282] 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.

[0283] 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 keep the door body open and to continuously separate the first matching part and the second matching part.

[0284] When the door body 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.

[0285] When the door 3 opens to the angle G B1 Then, the door 3 and the box 1 continue to move in the opening direction, the elastic energy stored in the elastic deformation of the second matching part is released, and the second matching part recovers to the relaxed state. The second matching part is separated from the first matching part, and the door body 3 is separated from the box body 1.

[0286] 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.

[0287] 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;

[0288] When the door is opened to the angle G B1 Afterwards, the elastic energy stored in the elastic deformation of the second matching portion is released.

[0289] That is, the door body 3 opens from the angle G0 to the angle G B1 During the process, the elastic deformation of the second matching portion 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 continued opening process, the elastic force of the second matching portion is released.

[0290] In some embodiments of the present application, G B2 =G B1 .

[0291] In some embodiments of the present application, the second matching portion is disposed on a side of the second shaft 6 and the guide portion 8 away from the door side wall 33. The second matching portion is configured as a lock hook. Specifically, the lock hook first extends to a side away from the door side wall 33, and then bends to a side close to the door rear wall 32 and the door side wall 33, with the opening of the lock hook facing the door side wall 33. The free end of the lock hook is located on a side close to the door rear wall 32.

[0292] In some embodiments of the present application, the first matching portion is disposed on a side of the hinge plate 4 away from the first body side wall. The first matching portion is configured as a stopper. A side of the stopper close to the box body 1 has a hooking gap.

[0293] When the door 3 is in the closed state (or G0), the free end of the lock hook is received in the hook gap, the stopper is located in the lock hook, and the lock hook on the door 3 hooks the stopper on the hinge plate 4, thereby locking the door 3 and the cabinet 1, and preventing the door 3 from being closed tightly and leaking cold to affect the refrigeration / freezing effect of the refrigerator 100. When the door 3 is opened, the lock hook is deformed by force and overcomes the obstruction of the stopper, thereby breaking away from the stopper to achieve unlocking of the door 3 and the cabinet 1.

[0294] When the door body 3 is opened from the closed state (or G0), the door body 3 gradually opens under the action of external force. 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.

[0295] Then, under the action of external force, the door body 3 continues to open, the stopper interacts with the lock hook, the lock hook undergoes elastic deformation, 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).

[0296] When the door body 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.

[0297] When the door 3 opens to the angle G B1 Then, the door 3 is opened and 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 escape from the hook gap, the lock hook is separated from the stopper, and the door body 3 is separated from the box body 1.

[0298] In some embodiments of the present application, during the process in which the first matching portion and the second matching portion are unlocked from the locked state and the elastic deformation amount of the second matching portion continues to increase, the first direction displacement Second direction displacement As described 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.

[0299] In some embodiments of the present application, when the first matching part and the second matching part are unlocked from the locked state and the elastic deformation of the second matching part is continuously increased, 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. In the above, when the first matching part and the second matching part are unlocked and the elastic deformation of the second matching part is continuously increased, 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 conducive to the unlocking of the door body and the box body.

[0300] It should be noted that 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 continuously increases includes the moment when the elastic deformation of the second matching portion reaches the maximum.

[0301] In some embodiments of the present application, the door body 3 is opened from a locked state between the first matching part and the second matching part. As the door body 3 is opened, the second matching part undergoes elastic deformation. During the gradual release of the elastic energy stored in the elastic deformation of the second matching part, the second axis 6 moves relative to the guide part 7 to the position where the distance between it and the loading and unloading port in the plane is the largest.

[0302] It should be noted that the process of gradually releasing the elastic energy stored in the elastic deformation of the second matching portion includes the moment when the elastic deformation of the second matching portion reaches the maximum.

[0303] As described above, during the unlocking process of the first matching part and the second matching part, after the elastic deformation of the second matching part reaches the maximum, the interaction force between the first matching part and the second matching part 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 matching part and the second matching part; at this time, the second shaft 6 moves relative to the guide part 7 to the position where the distance between it and the access port is the largest in the plane. Based on the fact that the guide trajectory line S is convex toward the side away from the access port, the second shaft 6 has resistance to move 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 at the largest distance from the access port on the guide part 7 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 matching part and the second matching part is more stable and smooth.

[0304] 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.

[0305] 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.

[0306] When the door body 3 is opened to the angle G B1 Afterwards, the elastic energy stored by the elastic deformation of the second matching portion is released.

[0307] 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 close to the side wall of the first body and away from the access opening;

[0308] 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 plane where the first body side wall and the access opening are located; wherein G0<G B1 <G1<G2, or G0<G1<G B1 <G2;

[0309] 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 where the distance from the plane where the access port is located is the largest. Correspondingly, the second axis 6 is located on the guide portion 7 where the distance from the plane where the access port is located is the largest. Based on the fact that the guide trajectory line S is convex toward the side away from the plane where the access port is located, the second axis 6 has resistance to move 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 where the distance from the plane where the access port is located is the largest 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.

[0310] When the door body 3 is opened and the first matching part and the second matching part are unlocked, a large external force needs to be applied first to make the second matching part elastically deform under the action of the first matching part. After the elastic deformation of the second matching part reaches the maximum, the interaction force between the first matching part and the second matching part 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 3 opening still exists, resulting in a rapid increase in the relative movement speed of the first matching part and the second matching part, and the unlocking process of the first matching part and the second matching part is unstable, resulting in unstable opening of the door body 3.

[0311] Above 0°≤|G1-G B1 |≤3°, so that when the first matching portion and the second matching portion are unlocked, the second shaft 6 maintains stable movement relative to the guide portion 7, so that the unlocking process of the first matching portion and the second matching portion is more stable and smooth.

[0312] |G1-G B1 |>3°, the maximum deformation angle G of the first mating part and the second mating part unlocking B1, 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.

[0313] In some embodiments of the present application,

[0314] In some embodiments of the present application, the second guide point P2 is a 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 extreme guide point P2` / the second guide point P2).

[0315] 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 access port is located. When the second central axis P is located relative to the guide track line S, there is a certain distance between 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, there is a gap between the second shaft 6 and the end of the guide groove away from the first body side wall. The above arrangement prevents the second shaft 6 from colliding with the end of the guide portion 7 away from the first body side wall during the door 3 is opened, so as to avoid the impact between the second shaft 6 and the end of the guide portion 7 away from the first body side wall, thereby preventing the second shaft 6 from being damaged.
