Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household appliances, especially to a refrigerator. BACKGROUND

[0002] The embedded refrigerator is generally embedded into the customized cabinet as a whole, and the gap between the outer wall of the refrigerator and the inner wall of the cabinet is generally small in order to improve the fitting of the refrigerator embedded into the external cabinet. Therefore, when the refrigerator door is opened, the rotating door hinge vertical edge is easy to hit the inner wall of the external cabinet. Due to the space limitation of the cabinet, in order to ensure that the door body can be effectively opened, the corner of the door body should not exceed the size of the box body too much during the opening process. In order to ensure that the corner of the door body does not exceed the size of the box body too much during the opening process, the hinge assembly connected to the door body or the box body is used to move the door body inward by a certain distance when the door body is opened.

[0003] At present, the hinge assembly is mostly provided with two shafts matched with two grooves to control the movement of the door body. When the groove of the hinge assembly is arranged on the hinge plate, the groove arranged on the hinge plate needs to occupy the space of the hinge plate to hollow the hinge plate, which reduces the strength of the hinge plate and the groove arranged thereon. During the opening process of the door body, the shaft and the groove of the hinge assembly move relatively, and the shaft arranged on the door body rubs against the groove arranged on the hinge, which easily causes damage to the groove and the hinge plate. SUMMARY

[0004] The refrigerator provided by the present application limits the length of the guide track line by limiting the range of the central angle of the guide track line, so as to reduce the wear of the second shaft and the guide part, reduce the space occupation of the guide part to the hinge plate, and ensure the strength of the hinge plate.

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

[0006] a box body defining a plurality of containing cavities with taking and placing openings; the box body has a first body side wall and a second body side wall arranged oppositely;

[0007] a door body connected to the box body to close or open the containing cavities; the door body has:

[0008] a door front wall 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 the side of the door body away from the second body side wall in the closed state;

[0010] a hinge assembly connecting the door body and the box body to enable the door body to be flipped relative to the box body; the hinge assembly comprises:

[0011] A first hinge member is arranged on the box body and close to the first body side wall; the first hinge member comprises:

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

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

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

[0015] A second shaft is matched with the guide part;

[0016] A guide part is matched with the first shaft;

[0017] A center axis of the second shaft is recorded as a guide track S relative to a movement track of the guide part; the guide track S is a circular arc; the guide track S is convex to a side away from a plane where the taking and placing opening is located;

[0018] When the door body is opened to an angle G1`, a distance between a center axis of the second shaft and the first body side wall is the smallest; at this time, the center axis of the second shaft is located at a first limit guide point P1` of the guide track S;

[0019] When the door body is opened to an angle G2`, a distance between a center axis of the second shaft and the first body side wall is the largest; at this time, the center axis of the second shaft is located at a second limit guide point P2` of the guide track S;

[0020] Wherein, 20°≤∠P1`OP2`≤30°.

[0021] In the above technical solution, when ∠P1`OP2`<20°, ∠P1`OP2` is too small, the length of the guide track is too small, the length of the guide part is too small, the relative friction times of the second shaft relative to the guide part is too much, which increases the abrasion of the second shaft and the guide part, and reduces the service life of the hinge assembly.

[0022] When 30°<∠P1`OP2`, ∠P1`OP2` is too large, the length of the guide track is too large, the length of the guide part is too large, the guide part occupies a large space of the hinge plate, which reduces the strength of the hinge plate and also reduces the strength of the guide part, and reduces the service life of the hinge assembly.

[0023] The setting of 20°≤∠P1`OP2`≤30` limits the length of the guide track (guide part), which on the one hand reduces the relative friction times of the second shaft relative to the guide part to reduce the abrasion of the second shaft and the guide part, and on the other hand reduces the space occupation of the guide part to the hinge plate, avoids the reduction of the strength of the hinge plate, and ensures the service life of the hinge assembly.

[0024] In some embodiments, the maximum point of the distance between the guide trajectory line S and the plane where the taking and placing opening is located is recorded as a first guide point P1;

[0025] Wherein, 7°≤∠P2`OP1≤11°.

[0026] In the above technical solution, the stroke of the second shaft relative to the guide part between the first guide point P1 and the second limit guide point P2` is recorded as a second stroke.

[0027] When ∠P2`OP1<7°, ∠P2`OP1 is too small, the second stroke of the second shaft relative to the guide part between the first guide point P1 and the second limit guide point P2` is too small, and the movement amount of the door body relative to the cabinet along the width direction and the movement amount along the front and back direction are appropriately too small, which cannot effectively reduce the restriction of the space defined by the cabinet on the movement of the door body.

[0028] When 11°<∠P2`OP1, ∠P2`OP1 is too large, during the movement of the second shaft relative to the guide part between the first guide point P1 and the second limit guide point P2`, the distance between the second shaft and the first shaft in the direction perpendicular to the plane where the taking and placing opening is located is too large, which leads to that at least one segment of the movement of the door body relative to the cabinet has a displacement amount in the direction perpendicular to the plane where the taking and placing opening is located that is too large, resulting in that the movement amount of the door body relative to the cabinet along the width direction and the movement amount along the front and back direction are imbalanced, which cannot effectively reduce the restriction of the space defined by the cabinet on the movement of the door body.

[0029] In the present application, the setting of 7°≤∠P2`OP1≤11° makes the movement of the second shaft relative to the guide part between the first guide point P1 and the second limit guide point P2` appropriate in the direction perpendicular to the plane where the taking and placing opening is located, and the movement amount of the door body relative to the cabinet along the width direction and the movement amount along the front and back direction are appropriate, and the stroke is appropriate, so as to more efficiently reduce the restriction of the space defined by the cabinet on the movement of the door body.

[0030] In some embodiments, the maximum point of the distance between the guide trajectory line S and the plane where the taking and placing opening is located is recorded as a first guide point P1;

[0031] In the projection of the top wall of the cabinet, the distance between the center axis of the first shaft and the first guide point P1 in the direction perpendicular to the plane where the taking and placing opening is located is recorded as |QP1|1.

[0032] Wherein, 0mm≤|QP1|1≤4mm.

[0033] In the technical solution, when 4mm<|QP1|1, the second shaft is moved to the position where the distance between the guide part and the plane where the taking and placing opening is the largest, the distance between the second shaft and the first shaft in the direction perpendicular to the plane where the taking and placing opening is too large, the displacement of the door body relative to the cabinet in the direction perpendicular to the plane where the taking and placing opening is too large, the movement amount of the door body relative to the cabinet in the width direction is unbalanced with the movement amount in the front-back direction, and the restriction of the cabinet on the movement of the door body cannot be effectively reduced.

[0034] In the present application, the setting of 0mm≤|QP1|1≤4mm makes the second shaft move to the position where the distance between the guide part and the plane where the taking and placing opening is the largest, the second shaft is close to the first shaft in the direction perpendicular to the plane where the taking and placing opening is, the displacement of the door body relative to the cabinet in the direction perpendicular to the plane where the taking and placing opening is effectively controlled, the movement amount of the door body relative to the cabinet in the width direction is controlled with the movement amount in the front-back direction, the restriction of the cabinet on the movement of the door body is reduced, and the door body can be opened to a larger angle.

[0035] In some embodiments, the center axis of the first shaft relative to the movement track of the guide part is recorded as a guide track line F, the guide track line F extends from the end away from the door side wall to the side close to the door side wall and away from the door front wall first, and then extends to the side close to the door side wall and the door front wall.

[0036] In the technical solution, the extension trend of the track where the guide part guides the movement of the center axis of the first shaft is limited, the extension trend of the guide track line is divided into two sections, the track extension trend is simple, and the movement fluency of the first shaft relative to the guide part is improved.

[0037] In some embodiments, the point where the guide track line F is farthest away from the door side wall and closest to the door front wall is recorded as a first guide point K.

[0038] In the planar projection parallel to the top wall of the cabinet, the distance between the center axis of the second shaft and the first guide point K in the direction perpendicular to the door front wall is recorded as |PK|1; and 0mm≤|PK|1≤3mm.

[0039] In the technical solution, when 3mm<|PK|1, |PK|1 is too large, the distance between the second center axis P and the first guide point K on the guide track line which is farthest away from the door side wall is too large in the direction perpendicular to the door front wall; when the first center axis Q is located at the first guide point K during the movement of the door body relative to the cabinet, the distance between the second center axis and the first center axis in the direction perpendicular to the door front wall is too large, the inclination angle of the straight line where the first center axis and the second center axis are located relative to the plane where the taking and placing opening is too large, and the stability of the movement of the door body relative to the cabinet is poor.

[0040] In the present application, the setting of 0mm≤|PK|1≤3mm is that, in the direction perpendicular to the door front wall, the second shaft is close to the first guide point K on the guide trajectory line farthest from the door side wall; during the movement of the door body relative to the cabinet, when the first center shaft Q is located at the first guide point K when the door body is closed, in the direction perpendicular to the door side wall, the second center shaft P is close to the first center shaft, effectively ensuring the stability of the movement of the door body relative to the cabinet.

[0041] In some embodiments, the point on the guide trajectory line F farthest from the door front wall is denoted as a third guide point H;

[0042] In the planar projection parallel to the cabinet top wall, in the direction perpendicular to the door side wall, the distance between the center axis of the second shaft and the third guide point H is denoted as |PH|2; wherein 0mm≤|PH|2≤5mm.

[0043] In the above technical solution, when 5mm<|PH|2, |PH|2 is too large, in the direction perpendicular to the door side wall, the distance between the second shaft and the third guide point H on the guide trajectory line farthest from the door front wall is too large; during the movement of the door body relative to the cabinet, when the first center shaft Q moves to the third guide point H, the distance between the second center shaft and the first center shaft in the direction perpendicular to the door side wall is too large, the inclination angle of the straight line on which the first center shaft and the second center shaft are located relative to the plane on which the taking and placing opening is located is too large, at this time, the stability of the movement of the door body relative to the cabinet is poor.

[0044] In the present application, the setting of 0mm≤|PH|2≤5mm is that, in the direction perpendicular to the door side wall, the second shaft is close to the third guide point H on the guide trajectory line farthest from the door front wall; during the movement of the door body relative to the cabinet, when the first center shaft Q moves to the third guide point H, in the direction perpendicular to the door side wall, the second center shaft is close to the first center shaft, effectively ensuring the stability of the movement of the door body relative to the cabinet.

[0045] In some embodiments, the first shaft is located on the side of the guide portion away from the first body side wall, and the second shaft is located on the side of the guide portion close to the door front wall.

[0046] 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 limited, so that the structure of the hinge assembly is more compact, thereby ensuring the strength thereof.

[0047] In some embodiments,

[0052] During the process that the door body is opened from G4 to G5, the second shaft moves relative to the guide part to a side away from the first body side wall and the plane where the taking and placing opening is located; wherein G0

[0053] In the above technical solution, the movement direction of the second shaft relative to the guide part is divided into five stages relative to the movement direction of the cabinet, and different relative movement trends in different stages guide the movement of the door body, so as to guide the movement of the door body in the width direction and the front and back direction of the cabinet, thereby reducing the restriction of the cabinet on the door body and increasing the maximum angle that the door body can be opened in the cabinet.

[0054] In some embodiments, the guide part includes a first guide end away from the door side wall and a second guide end close to the door side wall;

[0055] During the process that the door body is opened from G0 to G5, the first guide end gradually moves away from the first shaft, and the second guide end gradually moves close to the first shaft;

[0056] During the process that the door body is opened from G0 to G1, the first guide end moves to a side away from the first body side wall and the plane where the taking and placing opening is located, and the second guide end moves to a side away from the first body side wall and close to the plane where the taking and placing opening is located;

[0057] During the process that the door body is opened from G1 to G2, the first guide end moves to a side close to the first body side wall and away from the plane where the taking and placing opening is located, and the second guide end moves to a side away from the first body side wall and close to the plane where the taking and placing opening is located;

[0058] During the process that the door body is opened from G2 to G5, the first guide end moves to a side close to the first body side wall and away from the plane where the taking and placing opening is located, and the second guide end moves to a side away from the first body side wall and the plane where the taking and placing opening is located; wherein G0

[0059] In the technical scheme, the first guide end and the second guide end of the guide part are divided into three stages relative to the movement direction of the cabinet, and different relative movement trends in different stages guide the movement of the door body to move in the width direction and the front-back direction of the cabinet, so as to reduce the restriction of the cabinet on the door body and increase the maximum angle of the door body that can be opened in the cabinet.

[0060] In a second aspect, a refrigerator is provided, comprising:

[0061] a cabinet defining a plurality of containing cavities with access openings; the cabinet has a first body side wall and a second body side wall arranged oppositely;

[0062] a door body connected to the cabinet to close or open the containing cavities; the door body has:

[0063] a door front wall away from the cabinet when the door body is closed;

[0064] 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 closed;

[0065] a hinge assembly connecting the door body and the cabinet to enable the door body to be flipped relative to the cabinet; the hinge assembly comprises:

[0066] a first hinge piece arranged on the cabinet and close to the first body side wall; the first hinge piece comprises:

[0067] a hinge plate connected to the cabinet;

[0068] a first shaft and a guide part arranged on the hinge plate;

[0069] a second hinge piece arranged on the door body; the second hinge piece comprises:

[0070] a second shaft cooperating with the guide part;

[0071] a guide part cooperating with the first shaft;

[0072] A center axis of the second shaft is recorded as a guide trajectory S relative to a movement trajectory of the guide part, the guide trajectory S is a circular arc, and the guide trajectory S protrudes to a side away from a plane where the access opening is located;

[0073] The maximum point of the distance between the guide trajectory S and the plane where the access opening is located is recorded as a first guide point P1;

[0074] During the opening process of the door body, when the opening angle of the door body is G1', the distance between the center axis of the second shaft and the first body side wall is the smallest; at this time, the center axis of the second shaft is located at the first limit guide point P1' of the guide trajectory S.

[0075] When the door body opening angle is G2`, the distance between the center axis of the second shaft and the first body side wall is the largest; at this time, the center axis of the second shaft is located at the second limit guide point P2` of the guide trajectory line S;

[0106] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary skilled in the art without creative labor belong to the scope of protection of the present application.

[0107] The embodiments of the present application provide a refrigerator 100, referring to Figures 1-20 The refrigerator 100 includes a cabinet 1 having a receiving cavity, a door body 3 connected to the cabinet 1 to open and close the receiving cavity, and a refrigeration device for supplying cold air to the receiving cavity. The cabinet 1 includes an inner container defining the receiving cavity, an outer shell connected to the outer side of the inner container to form the appearance of the refrigerator 100, and a thermal insulation layer provided between the inner container and the outer shell to thermally insulate the receiving cavity.

[0108] Among them, referring to Figure 1 The direction from the bottom wall of the cabinet 1 to the top wall of the cabinet 1 is the height direction. The direction in which the intersection line of the top wall and the rear wall of the cabinet 1 extends is the width direction. The direction orthogonal to the height direction and the width direction is the front-rear direction.

[0109] In some embodiments of the present application, the cabinet 1 defines a plurality of receiving cavities. The front end of the receiving cavity is formed with a taking and placing opening for taking and placing articles, and a user can place food into the receiving cavity or take food out of the receiving cavity through the taking and placing opening. The cabinet 1 is provided with a rotatable door body 3 to open or close the taking and placing opening of the receiving cavity. For example, the door body 3 is rotatably connected to the cabinet 1 through a hinge assembly located at the upper portion and a hinge assembly located at the lower portion. Among them, in the front-rear direction, the taking and placing opening of the cabinet 1 is located at the front side relative to the wall surface of the cabinet 1 opposite to the taking and placing opening (the rear wall of the cabinet 1).

[0110] In some embodiments of the present application, the plurality of accommodation cavities can include a refrigeration chamber and a freezing chamber to form accommodation cavities of different temperatures to store different items.

[0111] In some embodiments of the present application, the cabinet 1 includes a first body side wall (i.e., one of the left side wall and the right side wall of the cabinet 1) and a second body side wall (i.e., the other of the left side wall and the right side wall of the cabinet 1) oppositely arranged along the width direction of the cabinet 1. The hinge assembly is arranged on the cabinet 1 and close to the first body side wall to connect the door body 3 close to the first body side wall with the cabinet 1, so that the door body 3 can rotate relative to the cabinet 1 to open or close the access opening.

[0112] The door body 3 has a door front wall 31 away from the cabinet 1 when the door body 3 is closed, a door back wall 32 oppositely arranged with the door front wall 31, and a door side wall 33 close to the first body side wall and connected with the door front wall 31. For example, when the hinge assembly is located on the right side of the cabinet 1, the right side wall of the door body 3 is the door side wall 33. When the hinge assembly is located on the left side of the cabinet 1, the left side wall of the door body 3 is the door side wall 33. It should be noted that the door front wall 31 is the surface closest to the front when the door body 3 is in the closed state. When the door body 3 includes a glass panel on the front side thereof in the closed state, the door front wall 31 is the surface of the glass panel closest to the front. The door back wall 32 is the surface closest to the back when the door body 3 is in the closed state. When the door body 3 is in the closed state, the distance between the door front wall 31 of the door body 3 and the plane of the access opening is the largest, and the distance between the door back wall 32 of the door body 3 and the plane of the access opening is the smallest.

[0113] In some embodiments of the present application, the door side wall 33 is connected with the door front wall 31 and close to the pivot axis of the door body 3. The pivot axis of the door body 3 is close to the first body side wall.

[0114] The intersection of the door front wall 31 and the door side wall 33 of the door body 3 forms a first side edge W, and the intersection of the door side wall 33 and the door back wall 32 forms a second side edge N. When the door body 3 is closed, the first side edge W is located on the side away from the cabinet 1 of the second side edge N.

[0115] 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 intersection of the door front wall 31 and the door side wall 33 is roundly transitioned, a curved surface extending along the height direction of the door body 3 is formed. For ease of description, any straight line on the curved surface extending along the height direction of the door body 3 represents the first side edge W. Similarly, when the intersection of the door back wall 32 and the door side wall 33 is roundly transitioned, the intersection line of the planes where the door back wall 32 and the door side wall 33 are located can represent the second side edge N, or a straight line close to the position of the intersection line and parallel to the intersection line can represent the second side edge N. Figure 1 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 intersection of the door front wall 31 and the door side wall 33 is roundly transitioned, a curved surface extending along the height direction of the door body 3 is formed. For ease of description, any straight line on the curved surface extending along the height direction of the door body 3 represents the first side edge W. Similarly, when the intersection of the door back wall 32 and the door side wall 33 is roundly transitioned, the intersection line of the planes where the door back wall 32 and the door side wall 33 are located can represent the second side edge N, or a straight line close to the position of the intersection line and parallel to the intersection line can represent the second side edge N.

[0116] In some embodiments of the present application, a door seal is arranged on the rear wall 32 of the door body 3. When the door body 3 is closed, the door seal surrounds the taking and placing opening to effectively seal the taking and placing opening. When the door body 3 is closed, the door seal is attached to the front end surface of the cabinet 1 to effectively seal the connection between the door body 3 and the cabinet 1, thereby ensuring that the door body 3 seals the taking and placing opening and avoiding cold air overflow.

[0117] In the present application, the opening angle of the door body 3 is denoted as .

[0118] In some embodiments of the present application, the opening angle of the door body 3 is positive. The front wall 31 of the door body 3 is parallel to the plane on which the taking and placing opening is located.

[0119] In some embodiments of the present application, the opening angle of the door body 3 is positive. The rear wall 32 of the door body 3 is perpendicular to the plane on which the taking and placing opening is located.

[0120] In some embodiments of the present application, the opening angle of the door body 3 is positive. The side wall 33 of the door body 3 is parallel to the plane on which the taking and placing opening is located.

[0121] In some embodiments of the present application, the opening angle of the door body 3 is positive. The opening angle of the door body 3 relative to the cabinet 1 when the door body 3 is opened to open the taking and placing opening is positive. .

[0122] The door body 3 is moved in the closing direction from to further press the door seal, and the opening angle of the door body 3 is negative.

[0123] In some embodiments of the present application, the opening angle of the door body 3 is negative. The door body 3 is denoted as a closed state.

[0124] In some embodiments of the present application, the opening angle of the door body 3 in the closed state is negative. That is, in the closed state of the door body 3, the deformation amount of the door seal pressed by the door body 3 is greater than , and the sealing effect of the door body 3 and the cabinet 1 is better. In some embodiments of the present application, the opening angle of the door body 3 in the closed state is negative.

[0125] In some embodiments of the present application, the hinge assembly includes a first hinge piece and a second hinge piece, and the first hinge piece cooperates with the second hinge piece and can rotate relative to the second hinge piece to enable the door body 3 and the cabinet 1 to rotate relative to each other.

[0126] In some embodiments of the present application, the first hinge member is arranged on the cabinet 1 and close to one of the side walls; in the present embodiment, the first hinge member close to the first side wall is taken as an example for illustration. The second hinge member is arranged on the door body 3 close to the end of the first hinge member, and the first hinge member cooperates with the second hinge member to allow the cabinet 1 and the door body 3 to rotate relative to each other.

[0127] With reference to Figures 2 to 4 The first hinge member includes a hinge plate 4. Specifically, the hinge plate 4 includes a connecting portion 41 connected to the cabinet 1, and an extension portion 42 extending forward from the connecting portion 41. The extension portion 42 can be arranged parallel to the top wall of the cabinet 1. The connecting portion 41 can be fastened to the top wall of the cabinet 1 by fasteners such as screws, pins and bolts. Specifically, for the hinge at the upper end of the door body 3, the connecting portion 41 is connected to the top wall of the cabinet 1. For the hinge at the lower end of the door body 3, the connecting portion 41 is connected to the front end face of the cabinet 1.

[0128] In some embodiments of the present application, the first hinge member includes a first shaft 5 and a guide portion 7. The first shaft 5 and the guide portion 7 are both connected to the cabinet 1.

[0129] In some embodiments of the present application, the first shaft 5 and the guide portion 7 are both arranged on the hinge plate 4. The first shaft 5 is located on the side of the guide portion 7 away from the first side wall. The above arrangement allows the first shaft 5 and the guide portion 7 to be arranged along the width direction of the cabinet 1, reducing the space occupation in the front-rear direction of the cabinet 1 and making the structure of the first hinge member more compact.

[0130] 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 end of the door body 3 close to the first hinge member. The second shaft 6 is located on the side of the guide portion 8 close to the front wall 31 of the door body 3.

[0131] The first shaft 5 is adapted to the guide portion 8; the second shaft 6 is adapted to the guide portion 7; during the rotation of the door body 3 to open or close, the first shaft 5 moves relative to the guide portion 8, and the second shaft 6 moves relative to the guide portion 7, so that the door body 3 moves at least a certain distance along the width direction of the cabinet 1 while rotating to open the taking and placing opening.

[0132] The central axis of the first shaft 5 is denoted as a first central axis Q. The central axis of the second shaft 6 is denoted as a second central axis P. When the door body 3 is opened, the trajectory line of the second central axis P moving relative to the guide portion 7 is denoted as a guide trajectory line S.

[0133] In some embodiments of the present application, the guide trajectory S is a curve. The curve-shaped guide trajectory S protrudes away from the plane where the taking and placing opening is located. That is, the guide trajectory S extends first towards the side close to the first body side wall and away from the plane where the taking and placing opening is located, and then extends towards the side close to the first body side wall and the plane where the taking and placing opening is located. The above extension trend of the guide trajectory S is divided into two sections, and the trajectory extension trend is simple, which improves the movement fluency of the second shaft relative to the guide portion.

[0134] In some embodiments of the present application, the guide trajectory S is a circular arc, so that the movement of the second shaft 6 relative to the guide portion 7 is more fluent.

[0135] In some embodiments of the present application, the guide portion 7 is provided as a guide groove. The guide groove is a continuous curve groove, and the curve groove protrudes away from the plane where the taking and placing opening is located.

[0136] In some embodiments of the present application, the guide groove is a circular arc groove.

[0137] In some embodiments of the present application, the guide groove includes a guide groove bottom, a circumferential groove wall surrounding the guide groove bottom, and a guide groove opening defined by the circumferential groove wall and oppositely arranged with 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 groove wall of the guide groove to guide the second shaft 65 when the second shaft 65 moves relative to the guide groove. The above arrangement guides the second shaft 6 through the circumferential groove wall of the guide groove, and the relative movement is more stable.

[0138] In some embodiments of the present application, the guide groove includes a guide groove opening arranged on the hinge plate 4. The second shaft 6 penetrates through the guide groove opening, and the circumferential side wall of the second shaft 6 cooperates with the hinge plate 4 surrounding the guide groove opening 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 guiding the second shaft 6 by the guide groove, and is convenient to process.

[0139] Referring to Figure 5 In some embodiments of the present application, the center of the circular arc-shaped guide trajectory S is denoted as a guide center O. The guide center O is located on the side of the guide trajectory S close to the plane where the taking and placing opening is located. The radius of the circular arc-shaped guide trajectory S is denoted as a guide radius R.

[0140] In some embodiments of the present application, 8mm≤R≤12mm.

[0141] When R<8mm, the guide radius R is too small, the curvature of the guide trajectory S is too large, and the movement speed of the second shaft 6 relative to the guide portion 7 changes too fast.

[0142] When 12mm < R, the guide radius R is too large, the curvature of the guide trajectory S is too small, the change of the movement speed of the second shaft 6 relative to the guide portion 7 is too small, the length of the guide trajectory is too long, the guide portion 7 occupies a large space of the hinge plate 4, the strength of the hinge plate 4 is reduced, and the strength of the guide portion 7 is also reduced, which reduces the service life of the hinge assembly.

[0143] When 8mm < R, the curvature of the guide trajectory S is too large, which can avoid the change of the movement speed of the second shaft 6 relative to the guide portion 7 being too fast, so as to improve the stability of the movement of the door body 3 relative to the cabinet 1.

[0144] When R < 12mm, the guide trajectory S is too small, which can avoid the movement speed of the second shaft 6 relative to the guide portion 7 being too small, so as to avoid the length of the guide trajectory being too long, reduce the space occupied by the guide portion 7 to the hinge plate 4, avoid the strength of the hinge plate 4 being reduced, and ensure the service life of the hinge assembly.

[0145] The setting of 8mm < R < 12mm can make 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 cabinet 1. On the other hand, the area range occupied by the guide portion 7 to the hinge plate 4 is limited, so as to ensure the strength of the hinge plate 4 and the guide portion 7, and effectively ensure the service life of the hinge assembly.

[0146] In the projection of the top wall of the cabinet 1, the guide center O is located on the side of the first center axis Q close to the plane where the taking and placing opening is located and the first body side wall.

[0147] In some embodiments of the present application, the maximum point of the distance between the guide trajectory S and the plane where the taking and placing opening is located is recorded as a first guide point P1. The first center axis Q is located on the side of the first guide point P1 close to the plane where the taking and placing opening is located and away from the first body side wall.

[0148] In some embodiments of the present application, when the door body 3 is opened to an angle , the distance between the second center axis P and the first body side wall is the smallest. At this time, the second center axis P is located at the first limit guide point P1` of the guide trajectory S.

[0149] When the door body 3 is opened to an angle , the distance between the second center axis P and the first body side wall is the largest. At this time, the second center axis P is located at the second limit guide point P2` of the guide trajectory S.

[0150] In some embodiments of the present application, in the projection of the plane where the top wall of the cabinet 1 is located, the distance between the first center axis Q and the first guide point P1 in the direction perpendicular to the plane where the taking and placing opening is located is denoted as |QP1|1; the distance between the first center axis Q and the first limit guide point P1` is denoted as |QP1`|1; and the distance between the first center axis Q and the second limit guide point P2` is denoted as |QP2`|1.

[0151] In some embodiments of the present application, in the projection of the plane where the top wall of the cabinet 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 center axis Q away from the plane where the taking and placing opening is located. That is, the trajectory segment of the guide trajectory S extending from the first limit guide point P1` to the second limit guide point P2` through the first guide point P1 is located on the side of the first center axis Q away from the plane where the taking and placing opening is located.

[0152] In some embodiments of the present application, |QP1`|1≤|QP1|1, |QP2`|1≤|QP1|1. Wherein, |QP1|1≠|QP1`|1 and |QP1|1≠|QP2`|1 do not hold at the same time.

[0153] In some embodiments of the present application, 0mm≤|QP1|1≤4mm.

[0154] When 4mm<|QP1|1, the second shaft 6 moves to the position where the distance between the guide portion 7 and the plane where the taking and placing opening is located is the largest, the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane where the taking and placing opening is located is too large, which leads to that the displacement amount of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane where the taking and placing opening is located is too large, and the movement amount of the door body 3 relative to the cabinet 1 in the width direction is unbalanced with the movement amount in the front-back direction, which cannot effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0155] In the present application, the setting of 0mm≤|QP1|1≤4mm makes the second shaft 6 move to the position where the distance between the guide portion 7 and the plane where the taking and placing opening is located is the largest, and in the direction perpendicular to the plane where the taking and placing opening is located, the second shaft 6 is close to the first shaft 5, which effectively controls the displacement amount of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane where the taking and placing opening is located, controls the movement amount of the door body 3 relative to the cabinet 1 in the width direction, and controls the movement amount in the front-back direction, so as to reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3, and enable the door body 3 to be opened to a larger angle.

[0156] In some embodiments of the present application, 0mm≤|QP1`|1≤2mm.

[0157] When 2mm < |QP1'| < 3mm, the second shaft 6 moves to the position where the distance between the guide part 7 and the first body side wall is the largest, and the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane where the taking and placing opening is located is too large, which causes the displacement of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane where the taking and placing opening is located to be too large, and causes the movement amount of the door body 3 relative to the cabinet 1 in the width direction to be unbalanced with the movement amount in the front-back direction, which cannot effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0158] In the present application, the setting of 0mm < |QP1'| < 2mm makes the second shaft 6 move to the position where the distance between the guide part 7 and the first body side wall is the smallest, and the second shaft 6 is close to the first shaft 5 in the direction perpendicular to the plane where the taking and placing opening is located, which effectively controls the displacement of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane where the taking and placing opening is located, and controls the movement amount of the door body 3 relative to the cabinet 1 in the width direction to be balanced with the movement amount in the front-back direction, which reduces the restriction of the space defined by the cabinet 2 on the movement of the door body 3, and enables the door body 3 to be opened to a larger angle.

[0159] In some embodiments of the present application, 0mm < |QP2'| < 3mm.

[0160] When 3mm < |QP2'|, the second shaft 6 moves to the position where the distance between the guide part 7 and the first body side wall is the largest, and the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane where the taking and placing opening is located is too large, which causes the displacement of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane where the taking and placing opening is located to be too large, and causes the movement amount of the door body 3 relative to the cabinet 1 in the width direction to be unbalanced with the movement amount in the front-back direction, which cannot effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0161] In the present application, the setting of 0mm < |QP2'| < 3mm makes the second shaft 6 move to the position where the distance between the guide part 7 and the first body side wall is the largest, and the second shaft 6 is close to the first shaft 5 in the direction perpendicular to the plane where the taking and placing opening is located, which effectively controls the displacement of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane where the taking and placing opening is located, and controls the movement amount of the door body 3 relative to the cabinet 1 in the width direction to be balanced with the movement amount in the front-back direction, which reduces the restriction of the space defined by the cabinet 2 on the movement of the door body 3, and enables the door body 3 to be opened to a larger angle.

[0162] The above definitions of 0mm≤|QP1|1≤4mm, 0mm≤|QP1`|1≤2mm, and 0mm≤|QP2`|1≤3mm jointly define the overall trend of the guide trajectory S, so that during the opening of the door body 3, the second shaft 6 is always close to the first shaft 5 in the direction perpendicular to the plane of the taking and placing opening, so as to effectively control the displacement of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane of the taking and placing opening, and control the movement amount of the door body 3 relative to the cabinet 1 in the width direction and the movement amount in the front-back direction, so that the total displacement of each stage can meet the requirements of each stage during the opening of the door body 3, and at the same time, the restriction of the space of the cabinet 2 on the movement of the door body 3 is reduced, so that the door body 3 can be opened to a larger angle.

[0163] In some embodiments of the present application, 20°≤∠P1`OP2`≤30°.

[0164] When ∠P1`OP2`<20°, the ∠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 relative friction frequency of the second shaft 6 relative to the guide portion 7 is too high, which increases the wear of the second shaft 6 and the guide portion 7 and reduces the service life of the hinge assembly.

[0165] When 30°<∠P1`OP2`, the ∠P1`OP2`is too large, the length of the guide trajectory is too large, the length of the guide portion 7 is too large, the guide portion 7 occupies a large space of the hinge plate 4, which reduces the strength of the hinge plate 4 and also reduces the strength of the guide portion 7, thereby reducing the service life of the hinge assembly.

[0166] When 20°≤∠P1`OP2`, the length of the guide trajectory is limited within a reasonable range, and the relative friction frequency of the second shaft 6 relative to the guide portion 7 is limited, thereby reducing the wear of the second shaft 6 and the guide portion 7 and ensuring the service life of the hinge assembly.

[0167] When ∠P1`OP2`≤30°, the length of the guide trajectory is limited within a reasonable range, which reduces the space occupation of the guide portion 7 to the hinge plate 4 and avoids the reduction of the strength of the hinge plate 4, thereby ensuring the service life of the hinge assembly.

[0168] The setting of 20°≤∠P1`OP2`≤30° limits the length of the guide trajectory (the guide portion 7), which on the one hand reduces the relative friction frequency of the second shaft 6 relative to the guide portion 7 to reduce the wear of the second shaft 6 and the guide portion 7, and on the other hand reduces the space occupation of the guide portion 7 to the hinge plate 4 to avoid the reduction of the strength of the hinge plate 4, thereby ensuring the service life of the hinge assembly.

[0169] In some embodiments of the present application, 12°≤∠P1`OP1≤20°.

[0170] The stroke of the second shaft 6 moving relative to the guide portion 7 between the first guide point P1 and the first limit guide point P1` is recorded as a first stroke.

[0171] When ∠P1`OP1<12°, ∠P1`OP1 is too small, the first stroke of the second shaft 6 moving relative to the guide portion 7 between the first guide point P1 and the first limit guide point P1` is too small, the first stroke of the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front-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.

[0172] When 20°<∠P1`OP1, ∠P1`OP1 is too large, during the movement of the second shaft 6 relative to the guide portion 7 between the first guide point P1 and the first limit guide point P1`, the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane of the taking and placing opening is too large, at least one part of the movement of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane of the taking and placing opening is too large, the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front-back direction are imbalanced, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0173] When 12°≤∠P1`OP1, the first stroke of the second shaft 6 moving relative to the guide portion 7 between the first guide point P1 and the first limit guide point P1` meets the movement requirement of the door body 3, the first stroke of the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front-back direction meets the movement requirement of the door body 3, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 can be effectively reduced.

[0174] When ∠P1`OP1≤20°, during the movement of the second shaft 6 relative to the guide portion 7 between the first guide point P1 and the first limit guide point P1`, the second shaft 6 is close to the first shaft 5 in the direction perpendicular to the plane of the taking and placing opening, the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front-back direction are effectively controlled, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 can be effectively reduced.

[0175] The setting of 12°≤∠P1`OP1≤20° in the present application makes the second shaft 6 move to the guide portion 7 during the movement between the first guide point P1 and the first limit guide point P1`, the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front-back direction are appropriate, and the stroke meets the movement requirement of the door body 3, so that the restriction of the space defined by the cabinet 2 on the movement of the door body 3 can be more effectively reduced.

[0176] In some embodiments of the present application, 7°≤∠P2`OP1≤11°.

[0177] The stroke of the second shaft 6 moving between the first guide point P1 and the second limit guide point P2` relative to the guide part 7 is recorded as a second stroke.

[0178] When ∠P2`OP1<7°, ∠P2`OP1 is too small, the second stroke of the second shaft 6 moving between the first guide point P1 and the second limit guide point P2` relative to the guide part 7 is too small, the second stroke of the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front-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.

[0179] When 11°<∠P2`OP1, ∠P2`OP1 is too large, during the movement of the second shaft 6 between the first guide point P1 and the second limit guide point P2` relative to the guide part 7, the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane of the taking and placing opening is too large, which leads to that at least one section of the movement of the door body 3 relative to the cabinet 1 has a displacement in the direction perpendicular to the plane of the taking and placing opening that is too large, and the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front-back direction are imbalanced, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0180] When 7°≤∠P2`OP1, the second stroke of the second shaft 6 moving between the first guide point P1 and the second limit guide point P2` relative to the guide part 7 meets the movement requirement of the door body 3, the second stroke of the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front-back direction meets the movement requirement of the door body 3, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 can be effectively reduced.

[0181] When ∠P2`OP1≤11°, during the movement of the second shaft 6 between the first guide point P1 and the second limit guide point P2` relative to the guide part 7, the second shaft 6 is close to the first shaft 5 in the direction perpendicular to the plane of the taking and placing opening, the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front-back direction are effectively controlled, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 can be effectively reduced.

[0182] In the present application, the setting of 7°≤∠P2`OP1≤11° makes the second shaft 6 move to the guide part 7 in the process of moving between the first guide point P1 and the second limit guide point P2`, in the direction perpendicular to the plane of the taking and placing opening, the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front-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.

[0183] In some embodiments of the present application, 1.6≤∠P1`OP1:∠P2`OP1≤2.

[0184] 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 cabinet 1 in the width direction and the movement amount in the front-back direction are appropriately the first stroke 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. In addition, the ratio of the first stroke to the second stroke is too small, and the first stroke and the second stroke distribution amount of the door body 3 relative to the cabinet 1 when moving is unbalanced, and the displacement amount requirement of the door body 3 in each stage of opening cannot be met.

[0185] When 2<∠P1`OP1: ∠P2`OP1, ∠P1`OP1: ∠P2`OP1 is too large, the first stroke is too large, and there is a case that the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane of the taking and placing opening is too large, which causes at least one segment of the movement of the door body 3 relative to the cabinet 1 to have a displacement amount in the direction perpendicular to the plane of the taking and placing opening that is too large, resulting in imbalance between the movement amount of the door body 3 relative to the cabinet 1 in the width direction and the movement amount in the front-back direction, and the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced. In addition, the ratio of the first stroke to the second stroke is too large, and the first stroke and the second stroke distribution amount of the door body 3 relative to the cabinet 1 when moving is unbalanced, and the displacement amount requirement of the door body 3 in each stage of opening cannot be met.

[0186] When 1.6≤∠P1`OP1: ∠P2`OP1, the first stroke meets the movement requirement of the door body 3, and the movement amount of the door body 3 relative to the cabinet 1 in the width direction and the movement amount in the front-back direction are appropriately the first stroke that meets the movement requirement 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 within an appropriate range to control the relative amount of the first stroke and the second stroke of the door body 3 relative to the cabinet 1 when moving, which can meet the displacement amount requirement of the door body 3 in each stage of opening.

[0187] When ∠P1`OP1≤20°, during the movement of the first stroke, the second shaft 6 is close to the first shaft 5 in the direction perpendicular to the plane of the taking and placing opening, which effectively controls the movement amount of the door body 3 relative to the cabinet 1 in the width direction and the movement amount in the front-back direction, and 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 within an appropriate range to control the relative amount of the first stroke and the second stroke of the door body 3 relative to the cabinet 1 when moving, which can meet the displacement amount requirement of the door body 3 in each stage of opening.

[0188] In the present application, the setting of 1.6≤∠P1`OP1:∠P2`OP1≤2 makes the movement amount of the door body 3 relative to the cabinet 1 in the width direction and the movement amount of the door body 3 relative to the cabinet 1 in the front-back direction appropriate in the direction perpendicular to the plane where the taking and placing opening is located during the movement of the first stroke, and the stroke appropriately meets the movement demand 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. In addition, the ratio of the first stroke to the second stroke is limited within a suitable range, so as to control the relative amount of the first stroke and the second stroke of the door body 3 relative to the cabinet 1 when moving, and meet the displacement demand of the door body 3 in each stage of opening.

[0189] In the projection of the plane where the top wall of the cabinet 1 is located, the distance between the first center axis Q and the center O of the guide circle in the direction perpendicular to the plane where the taking and placing opening is located is denoted as |QO|1. 3≤|QO|1: |QP1|1.

[0190] When |QO|1: |QP1|1<3, |QO|1: |QP1|1 is too small, and when the second shaft 6 moves to the position where the distance between the guide part 7 and the plane where the taking and placing opening is located is the largest, the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane where the taking and placing opening is located is too large, which leads to that the displacement amount of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane where the taking and placing opening is located is too large, and the movement amount of the door body 3 relative to the cabinet 1 in the width direction and the movement amount of the door body 3 relative to the cabinet 1 in the front-back direction are unbalanced, which cannot effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0191] In the present application, the setting of 3≤|QO|1: |QP1|1 makes the second shaft 6 close to the first shaft 5 in the direction perpendicular to the plane where the taking and placing opening is located when the second shaft 6 moves to the position where the distance between the guide part 7 and the plane where the taking and placing opening is located is the largest, which effectively controls the displacement amount of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane where the taking and placing opening is located, controls the movement amount of the door body 3 relative to the cabinet 1 in the width direction and the movement amount of the door body 3 relative to the cabinet 1 in the front-back direction, reduces the restriction of the space defined by the cabinet 2 on the movement of the door body 3, and enables the door body 3 to be opened to a larger angle.

[0192] Referring to Figure 6 , when the door body 3 is opened, the second shaft 6 moves relative to the guide part 7, and the trajectory line of the first center axis Q relative to the guide part 8 is denoted as a guide trajectory line F.

[0193] In some embodiments of the present application, the guide trajectory line F includes a first guide segment, which extends from one 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.

[0194] In some embodiments of the present application, the distance between one end of the first guide segment away from the door side wall 33 and the second center axis P first decreases and then increases.

[0195] In some embodiments of the present application, the guide trajectory line F comprises a second guide segment, which extends from an end thereof away from the door side wall 33 to a side close to the door side wall 33 and the door front wall 31.

[0196] In some embodiments of the present application, the second guide segment increases in distance from the second central axis P at an end thereof away from the door side wall 33 and then decreases.

[0197] In some embodiments of the present application, the guide trajectory line F comprises a first guide segment and a second guide segment connected thereto. The guide trajectory line F extends from an end of the first guide segment away from the second guide segment 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 guide trajectory line is divided into two segments, and the extension trend of the trajectory thereof is simple, which improves the smoothness of the movement of the first shaft relative to the guide portion.

[0198] In some embodiments of the present application, the guide trajectory line F is in a curve shape. The guide trajectory line F in the curve shape protrudes to a side away from the door front wall 31. The guide trajectory line F comprises a first guide segment and a second guide segment connected to an end of the first guide segment close to the door side wall 33. Specifically, the guide trajectory 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.

[0199] In some embodiments of the present application, the distance between an end of the guide trajectory line F away from the door side wall 33 and the door front wall 31 is less than the distance between an end of the guide trajectory line F close to the door side wall 33 and the door front wall 31.

[0200] In some embodiments of the present application, a point of the guide trajectory line F away from the door side wall 33 and closest to the door front wall 31 is recorded as a first guide point K. A point of the guide trajectory line F close to the door side wall 33 and closest to the door front wall 31 is recorded as a second guide point J. A point of the guide trajectory line F farthest from the door front wall 31 is recorded as a third guide point H.

[0201] Corresponding to the guide portion 8, a point of the guide portion 8 away from the door side wall 33 and closest to the door front wall 31 is recorded as a first guide boundary point K`. A point of the guide portion 8 close to the door side wall 33 and closest to the door front wall 31 is recorded as a second guide boundary point J`. A point of the guide portion 8 farthest from the door front wall 31 is recorded as a third guide boundary point H`.

[0202] 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 cooperating 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.

[0203] 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 on which the first guide boundary point K' and the first guide point K are located 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 shaft 5.

[0204] 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 on which the second guide boundary point J' and the second guide point J are located 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 shaft 5.

[0205] 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 on which the third guide boundary point H' and the third guide point H are located 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 shaft 5.

[0206] In the actual determination of the positions of the first guide point K, the second guide point J, and the third guide point H, the positions of the first guide boundary point K', the second guide boundary point J', and the third guide boundary point H' can be obtained by measuring tools, and the positions of the corresponding first guide point K, the second guide point J, and the third guide point H can be determined 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 shaft 5, the distance between the second guide boundary point J' and the second guide point J is equal to the radius of the first shaft 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 shaft 5.

[0207] It should be noted that the "equal to" in the distance between the first guide boundary point K' and the first guide point K, the distance between the second guide boundary point J' and the second guide point J, and the distance between the third guide boundary point H' and the third guide point H includes the deviation caused by machining errors and the like.

[0208] It can be provided that the "equal to" above includes the case that the difference between the two equal objects is any value within 0-2 mm.

[0209] In some embodiments of the present application, when the door body 3 is in the closed state, the first center axis Q is located at the first guide point K of the guide trajectory line F.

[0210] In some embodiments of the present application, under the limitation of the guide part 8, the guide part 7, the first shaft 5 and the second shaft 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.

[0211] It should be noted that, under the premise that the door front wall 31 is perpendicular to the door side wall 33, 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.

[0212] And in the case that the door front wall 31 is not perpendicular to the door side wall 33, the direction perpendicular to the door front wall 31 only represents the distance in the direction perpendicular to the door front wall 31, and there is no necessary relationship with the parallel relationship with the door side wall 33. Similarly, the direction perpendicular to the door side wall 33 only represents the distance in the direction perpendicular to the door side wall 33, and there is no necessary relationship with the parallel relationship with the door front wall 31.

[0213] Referring to Figure 6 In the planar projection parallel to the top wall of the cabinet 1, the distance between the second center axis P and the third guide point H in the direction perpendicular to the door side wall 33 is denoted as |PH|2. Wherein, 0mm≤|PH|2≤5mm.

[0214] When 5mm<|PH|2, |PH|2 is too large, in the direction perpendicular to the door side wall 33, the distance between the second shaft 6 and the third guide point H on the guide trajectory line which is farthest from the door front wall 31 is too large; in the process of the movement of the door body 3 relative to the cabinet 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 inclination angle of the straight line on which the first center axis and the second center axis are located relative to the plane on which the access opening is located is too large. At this time, the stability of the movement of the door body 3 relative to the cabinet 1 is poor.

[0215] In the present application, the setting of 0mm≤|PH|2≤5mm, in the direction perpendicular to the door side wall 33, the second shaft 6 is close to the third guide point H on the guide trajectory line which is farthest from the door front wall 31; in the process of the movement of the door body 3 relative to the cabinet 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, effectively ensuring the stability of the movement of the door body 3 relative to the cabinet 1.

[0216] Referring to Figure 6In the planar projection parallel to the top wall of the cabinet 1, the distance between the second center axis P and the first guide point K in the direction perpendicular to the front wall 31 of the door is denoted as |PK|1. Wherein, 0mm≤|PK|1≤3mm.

[0217] When 3mm<|PK|1, |PK|1 is too large, the distance between the second center axis P and the first guide point K on the guide trajectory line farthest from the side wall 33 of the door in the direction perpendicular to the front wall 31 of the door is too large; when the first center axis Q is located to the first guide point K during the movement of the door body 3 relative to the cabinet 1, the distance between the second center axis and the first center axis in the direction perpendicular to the front wall 31 of the door is too large, and the inclination angle of the straight line where the first center axis and the second center axis are located relative to the plane where the access opening is located is too large. At this time, the stability of the movement of the door body 3 relative to the cabinet 1 is poor.

[0218] In the present application, the setting of 0mm≤|PK|1≤3mm is that, in the direction perpendicular to the front wall 31 of the door, the second axis 6 is close to the first guide point K on the guide trajectory line farthest from the side wall 33 of the door; during the movement of the door body 3 relative to the cabinet 1, when the door body 3 is closed, the first center axis Q is located to the first guide point K, and in the direction perpendicular to the side wall 33 of the door, the second center axis P is close to the first center axis, effectively ensuring the stability of the movement of the door body 3 relative to the cabinet 1.

[0219] In some embodiments of the present application, the first guide point K is located on the side of the second center axis P away from the front wall 31 of the door.

[0220] As shown in Figures 7-20 , the movement of the first axis 5 along the guide portion 8 is equivalent to the movement of the first center axis Q along the guide trajectory line K. 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, so that the door body 3 can move a certain distance inwards (towards the side wall of the second body) while rotating, so that the door body 3 does not interfere with the cabinet 2, and the effective opening of the door body 3 is ensured.

[0221] 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 process, the second axis 6 moves relative to the guide portion 7 throughout the process, and the door body 3 rotates around a point that remains dynamically changing relative to the cabinet 1 throughout the process.

[0222] In some embodiments of the present application, the line segment PQ is the axis line segment PQ in the projection of the plane in which the top wall of the cabinet 1 is located. The midpoint of the axis line segment PQ is the axis midpoint I. During the opening of the door body 3, the first shaft 5 moves relative to the guide portion 8 throughout the process, the second shaft 6 moves relative to the guide portion 7 throughout the process, and the door body 3 rotates around the point (the axis midpoint I) that remains dynamically changing relative to the cabinet 1 throughout the process. Under the above arrangement, during the opening of the door body 3, the first center shaft Q moves relative to the guide trajectory line F, the second center shaft P moves relative to the guide trajectory line S, and the door body 3 rotates with the axis midpoint I as the instantaneous rotation center.

[0223] During the opening of the door body 3, the position of the first shaft 5 relative to the cabinet 1 remains unchanged, the position of the second shaft 6 relative to the cabinet 1 changes constantly, the position and length of the axis line segment PQ relative to the cabinet 1 change constantly, the position of the axis midpoint I relative to the cabinet 1 changes constantly, and the rotation center axis of the rotation of the door body 3 relative to the cabinet 1 changes constantly.

[0224] The guide trajectory line F includes a second guide point J close to one end of the door side wall 33 and a first guide point K away from one end of the door side wall 33. The guide trajectory line F extends from the first guide point K to the third guide point H towards the side close to the door side wall 33 and away from the door front wall 31, and then extends from the third guide point H to the second guide point J towards the side close to the door side wall 33 and the door front wall 31.

[0225] 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.

[0226] As shown in Figures 7-20 With the first shaft 5 and the guide portion 7 (cabinet 1) arranged on the cabinet 1 as the stationary reference, the movement of the second shaft 6 along the guide portion 7 is equivalent to the movement of the second center shaft P along the guide trajectory line S, and the movement of the guide portion 8 relative to the first shaft 5 is equivalent to the movement of the guide trajectory line F through the first center shaft Q, so that the door body 3 can move a certain distance inward (towards the second body side wall) while rotating, thereby compensating for the outward displacement of the first side edge W caused by the pure rotation of the door body 3, effectively avoiding the mutual interference between the door body 3 and the cabinet 2 when the door body 3 is opened.

[0227] The movement of the door body 3 relative to the cabinet 1 is equivalent to the relative movement of the two in the plane in which the top wall of the cabinet 1 is located (or in the plane parallel to the top wall of the cabinet 1); that is, the movement of the door body 3 relative to the cabinet 1 is a relative movement in a two-dimensional plane. In the plane in which the top wall of the cabinet 1 is located, the movement of the guide portion 8 arranged on the door body 3 relative to the first shaft 5 arranged on the cabinet 1 (or the movement of the second shaft 6 arranged on the door body 3 relative to the guide portion 7 arranged on the cabinet 1) is equivalent to the movement of the door body 3 relative to the hinge plate 4, and also equivalent to the movement of the door body 3 relative to the cabinet 1.

[0228] In the plane of the top wall of the cabinet 1, a displacement coordinate system AOB is established on the side of the cabinet 1 close to the door body 3. Specifically, in the displacement coordinate system AOB, OB is perpendicular to the plane of the taking and placing opening, and OA is parallel to the plane of the taking and placing opening (or perpendicular to the first body side wall). In the displacement coordinate system AOB, the direction from the first body side wall to the second body side wall is defined as the positive direction of the A axis, and the direction from the plane of the taking and placing opening to the front wall 31 of the door body 3 when the door is closed (from back to front) is defined as the positive direction of the B axis.

[0229] It should be noted that during the opening of the door body 3, the displacement coordinate system AOB remains stationary relative to the cabinet 1 and does not move with the opening of the door body 3.

[0230] During the movement of the door body 3 relative to the cabinet 1, the door body 3 has a translational motion while rotating. The translational motion of the door body 3 is decomposed into a first direction motion perpendicular to the direction of the first body side wall (along the A axis) and a second direction motion perpendicular to the direction of the plane of the taking and placing opening (along the B axis). The displacement of the first direction perpendicular to the first body side wall (along the A axis) is denoted as the first direction displacement wherein the first direction displacement is inward; and the first direction displacement is outward. The modulus of the first direction displacement is denoted as

[0231] The displacement of the second direction perpendicular to the plane of the taking and placing opening (along the B axis) is denoted as the second direction displacement wherein the second direction displacement is forward; and the second direction displacement is backward. The modulus of the second direction displacement is denoted as

[0232] In some embodiments of the present application, the opening angle of the door body 3 is When the door body is in the closed state, the first shaft 5 is located at the end of the guide portion 8 away from the door side wall 33, and the second shaft 6 is located at the end of the guide portion 7 close to the first body side wall. The above defines the position of the first shaft relative to the guide portion and the position of the second shaft relative to the guide portion when the door body is closed, so as to define the movement trend of the first shaft relative to the guide portion and the second shaft relative to the guide portion in the first stage of opening of the door body, thereby defining the translational trend of the door body relative to the cabinet in the first stage of opening of the door body, so as to avoid interference between the door body and the cabinet, and to avoid or reduce the extrusion of the door body on the door seal.

[0233] In some embodiments of the present application, as Figure 7 ,Figure 8 、 Figures 13-16 As shown in FIG. 6, under the restriction of the guide part 8 and the first shaft 5, and the guide part 7 and the second shaft 6, the opening process of the door body 3 has a first stage. The first stage is as follows:

[0234] In some embodiments of the present application, the guide trajectory S includes a starting guide point P0 close to the first body side wall, and a first guide point P1 located on the side of the starting guide point P0 away from the first body side wall.

[0235] The first guide point P1 is located on the side of the starting guide point P0 away from the plane where the taking and placing opening is located.

[0236] The guide trajectory S extends from the starting guide point P0 to the first guide point P1 in the direction away from the first body side wall and the plane where the taking and placing opening is located.

[0237] When the opening angle of the door body 3 is , the second center axis P is located at the starting guide point P0 of the guide trajectory S.

[0238] When the opening angle of the door body 3 is , the second center axis P is located at the first guide point P1 of the guide trajectory S. At this time, the second center axis P is located at the position on the guide trajectory S farthest from the plane where the taking and placing opening is located. The first guide point P1 is located on the side of the starting guide point P0 away from the first body side wall and the plane where the taking and placing opening is located.

[0239] During the process of opening the door body 3 from to , the second center axis P moves relative to the guide trajectory S (the box body 1 or the hinge plate 4) from the starting guide point P0 to the first guide point P1.

[0240] During the process of opening the door body 3 from to , the second center axis P moves relative to the guide trajectory S (the box body 1 or the hinge plate 4) to the side away from the first body side wall and the plane where the taking and placing opening is located. That is, the second shaft 6 moves relative to the guide part 8 to the side away from the first body side wall and the plane where the taking and placing opening is located.

[0241] During the process of opening the door body 3 from to , the first center axis Q moves relative to the guide trajectory F (the door body 3) to the side close to the door side wall 33 and away from the door front wall 31. That is, the first shaft 5 moves relative to the guide part 8 to the side close to the door side wall 33 and away from the door front wall 31.

[0242] When the opening angle of the door body 3 is , the guide trajectory F passes through the first center axis Q, and the first center axis Q is located at the first guide point K of the guide trajectory F. That is, when the opening angle of the door body 3 is When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°. When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°.

[0243] When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°.

At this time, the opening angle of the door body 3 is 0°.

[0244] When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°. When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°. When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°. When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°. When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°. When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°. When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°.

[0245] When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°. When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°. When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°.

[0246] When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°. When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°.

When the door body 3 is opened to an angle of 0°, the first guide point K of the guide trajectory line F coincides with the first central axis Q. At this time, the opening angle of the door body 3 is 0°.

[0249] With the cabinet 1 (the hinge plate 4) as the reference object, the door body 3 is displaced in the first direction by a first direction displacement d1 from the closed position to the open position. When the door body 3 is displaced in the first direction by the first direction displacement d1 from the closed position to the open position, the first direction displacement d1 is a displacement of the door body 3 in the first direction from the closed position to the open position. When the door body 3 is displaced in the first direction by the first direction displacement d1 from the closed position to the open position, the first direction displacement d1 is a displacement of the door body 3 in the first direction from the closed position to the open position. The door body 3 has a tendency to move inward to compensate for the displacement of the first side edge W moving outward caused by the pure rotation of the door body 3, so as to avoid the collision between the first side edge W and the cabinet 2, which causes the door body 3 to be unable to continue to open; in addition, the door body 3 moves inward to reduce the limitation of the space of the cabinet 2 on the maximum angle of the door body 3 that can be opened in the space, so as to make the angle of the door body 3 of the refrigerator 100 placed in the cabinet 2 that can be opened larger, and facilitate the user to take and place the articles.

[0250] 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 taking and placing opening is located. The door body 3 is displaced in the first direction by a first direction displacement d1 from the closed position to the open position. When the door body 3 is displaced in the first direction by the first direction displacement d1 from the closed position to the open position, the first direction displacement d1 is a displacement of the door body 3 in the first direction from the closed position to the open position. When the door body 3 is displaced in the first direction by the first direction displacement d1 from the closed position to the open position, the first direction displacement d1 is a displacement of the door body 3 in the first direction from the closed position to the open position.

[0251] With the cabinet 1 (the hinge plate 4) as the reference object, the door body 3 is displaced in the first direction by a first direction displacement d1 from the closed position to the open position. When the door body 3 is displaced in the first direction by the first direction displacement d1 from the closed position to the open position, the first direction displacement d1 is a displacement of the door body 3 in the first direction from the closed position to the open position.

During the process of being opened to the position shown in FIG. 3B, the first direction displacement The door body 3 has a tendency to move inward, so as to compensate for the displacement of the first side edge W moving outward caused by the pure rotation of the door body 3, and avoid the collision between the first side edge W and the cabinet 2, which causes the door body 3 to be unable to continue to open; in addition, the door body 3 moves inward to reduce the limitation of the space of the cabinet 2 on the maximum angle of the door body 3 that can be opened in the space, so that the door body 3 of the refrigerator 100 placed in the cabinet 2 can be opened to a larger angle, and the user can take and place the articles more conveniently.

The door body 3 is opened to the position shown in FIG. 3B. The door body 3 is opened to the position shown in FIG. 3B. During the process of being opened to the position shown in FIG. 3B, the axis center point I moves relative to the cabinet 1 to the side close to the plane where the taking and placing opening is located.

During the process of being opened to the position shown in FIG. 3B, the second direction displacement The door body 3 has a tendency to move backward.

[0281] In some embodiments of the present application, the second midpoint I2 is located on the side of the first midpoint I1 away from the first body side wall and close to the plane where the taking and placing opening is located. The door body 3 is opened to the position shown in FIG. 3B. The door body 3 is opened to the position shown in FIG. 3B. During the process of being opened to the position shown in FIG. 3B, the axis center point I moves relative to the cabinet 1 to the side away from the first body side wall and close to the plane where the taking and placing opening is located.

[0282] With the cabinet 1 (the hinge plate 4) as a reference, the door body 3 is opened to the position shown in FIG. 3B. The door body 3 is opened to the position shown in FIG. 3B. During the process of being opened to the position shown in FIG. 3B, the first direction displacement The second direction displacement The door body 3 is opened to the position shown in FIG. 3B. The door body 3 is opened to the position shown in FIG. 3B. During the process of being opened to the position shown in FIG. 3B, the door body 3 has a tendency to move inward and backward while rotating to open the taking and placing opening.

[0283] In some embodiments of this application, the door body 3 is composed of... Open to During the process, That is, door body 3 is composed of Open to During the process, the translational movement of the door 3 is mainly inward, mainly to compensate for the displacement of the first side edge W caused by the simple rotation of the door 3, effectively avoiding interference between the first side edge W and the cabinet 2; at the same time, it effectively reduces the limitation of the space defined by the cabinet 2 on the maximum angle that the door 3 can open within it, so that the door 3 can be opened to a larger angle within the space defined by the cabinet 2.

[0284] In some embodiments of this application, the door body 3 is composed of... Open to The magnitude of the second directional displacement during the process Not greater than 3 gates Open to The magnitude of the second directional displacement during the process That is, door body 3 is composed of Open to The amount of backward displacement during the process is no greater than Open to The amount of forward displacement during the process. The above settings cause door 3 to move forward by... Open to During the process, the opening angle relative to door 3 is The state has an overall inward and forward translational displacement to compensate for the outward displacement of the first side edge W caused by the simple rotation of the door 3, effectively avoiding interference between the first side edge W and the cabinet 2; at the same time, it efficiently reduces the limitation of the space defined by the cabinet 2 on the maximum angle that the door 3 can open within it.

[0285] In some embodiments of this application, the refrigerator includes a locking assembly. The locking assembly includes a first mating part and a second mating part that cooperate with each other to lock and unlock the door 3 and the cabinet 1. The first mating part is located on the cabinet 1 near the lower end of the door 3, and the second mating part is located at the lower end of the door 3 to cooperate with the first mating part.

[0286] In some embodiments of this application, the first mating part is located on the side of the first hinge member away from the side wall of the first body. The second mating part is located on the side of the second hinge member away from the door side wall 33. The second mating part is used to cooperate with the first mating part to lock and unlock the door 3 and the housing 1.

[0287] In some embodiments of this application, the locking process between the door 3 and the housing 1 is as follows:

[0288] When the door body 3 is gradually closed from the open state, the second matching part gradually approaches the first matching part with the rotation closing of the door body 3.

[0289] When the door body 3 is closed to an angle G B0 , 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, and the second matching part is elastically deformed. Under the joint action of the external force and the force of the first matching part, the second matching part gradually approaches the first matching part, and the elastic deformation amount of the second matching part gradually increases.

[0290] When the door body 3 is closed to an angle G B2 , the elastic deformation amount of the second matching part reaches the maximum deformation amount in the closing process of the door body 3.

[0291] When the door body 3 continues to move in the closing direction after reaching the angle G B2 , the elastic energy stored by the elastic deformation of the second matching part is released, 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 and the first matching part are locked, and the locking of the door body 3 and the box body 1 is realized.

[0292] Therefore, G B0 > G B2 .

[0293] As can be seen from the above, in the process that the door body 3 is closed from the angle G B0 to the angle G B2 , the deformation amount of the elastic deformation of the second matching part continuously increases.

[0294] When the door body 3 is closed to the angle G B2 , the elastic deformation amount of the second matching part reaches the maximum deformation amount in the closing process of the door body 3.

[0295] In the process that the door body 3 is closed from the angle G B2 to the closed state, the elastic force of the second matching part is released, and the door body 3 is automatically closed.

[0296] That is, under the structure setting of the first matching part and the second matching part, in the process that the door body 3 is closed from the angle G B2 to the closed state, the door body 3 has the characteristics of automatic closing. Under the setting of the locking assembly, the door body 3 can be automatically closed in place, so that the door body 3 and the box body 1 are sealed and matched to avoid cold leakage.

[0297] In some embodiments of the present application, the unlocking process of the door body 3 and the box body 1 is as follows:

[0298] When the door body 3 is opened from the closed state (or the door body 3 is opened from the angle G0), the door body 3 is gradually opened. With the rotation opening of the door body 3, the second matching part and the first matching part interact, and the second matching part is elastically deformed.

[0299] With the continuous opening of the door body 3, the elastic deformation amount of the second matching part gradually increases; in the above process of continuously deforming the second matching part elastically, a large external force needs to be applied to make the door body continue to open, so that the first matching part and the second matching part are continuously separated.

[0300] When the door body 3 is opened to the angle G B1 , the elastic deformation amount of the second matching part reaches the maximum deformation amount in the opening process of the door body 3.

[0301] When the door body 3 is opened to the angle G B1 and continues to move in the opening direction, the elastic energy stored by the elastic deformation of the second matching part is released, and the second matching part returns 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.

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

[0303] The door body 3 is opened from the angle G0, the first matching part and the second matching part interact, and the second matching part is elastically deformed;

[0304] When the door body is opened to the angle G B1 , the elastic energy stored by the elastic deformation of the second matching part is released.

[0305] That is, in the process of opening the door body 3 from the angle G0 to the angle G B1 , the deformation amount of the elastic deformation of the second matching part continuously increases. When the door body 3 is opened to the angle G B1 , the elastic deformation amount of the second matching part reaches the maximum deformation amount in the closing process of the door body 3. In the process of continuously opening the door body 3 from the angle G B1 , the elastic force of the second matching part is released.

[0306] In some embodiments of the present application, G B2 =G B1 .

[0307] In some embodiments of the present application, the second matching part is arranged on the side of the second shaft 6 and the guide part 8 away from the door side wall 33. The second matching part is provided as a lock hook. Specifically, the lock hook first extends away from the door side wall 33, and then bends towards the side close to the door rear wall 32 and the door side wall 33, and the opening of the lock hook faces the door side wall 33. Among them, the free end of the lock hook is located on the side close to the door rear wall 32.

[0308] In some embodiments of the present application, the first matching part is arranged on the side of the hinge plate 4 away from the first body side wall. The first matching part is arranged as a stop part. The stop part has a hooking gap near the side of the box body 1.

[0309] When the door body 3 is in the closed state (or G0), the free end of the lock hook is accommodated in the hooking gap, the stop part is located in the lock hook, and the lock hook on the door body 3 hooks the stop part on the hinge plate 4, thereby locking the door body 3 and the box body 1, avoiding the leakage of cold energy due to the door body 3 not being closed tightly, which affects the refrigeration / freezing effect of the refrigerator 100. When the door body 3 is opened, the lock hook is deformed under the action of force to overcome the block of the stop part, thereby disengaging the stop part to achieve the unlocking of the door body 3 and the box body 1.

[0310] When the door body 3 is opened from the closed state (or G0), the door body 3 is gradually opened under the action of external force. With the rotation and opening of the door body 3, the free end of the lock hook interacts with the stop part, and the lock hook is elastically deformed.

[0311] Then under the action of external force, the door body 3 continues to open, the stop part interacts with the lock hook, the lock hook is elastically deformed, and under the joint action of external force and the force of the stop part, the lock hook gradually disengages from the hooking gap (at the same time, the stop part disengages from the lock hook).

[0312] When the door body 3 is opened to an angle G B1 , the elastic deformation amount of the lock hook reaches the maximum deformation amount in the closing process of the door body 3.

[0313] When the door body 3 is opened to an angle G B1 and continues to open, the elastic energy stored by the elastic deformation of the lock hook is gradually released, the lock hook returns to a relaxed state, and the free end of the lock hook further disengages from the hooking gap, the lock hook and the stop part are separated, and the door body 3 and the box body 1 are separated.

[0314] In some embodiments of the present application, during the process of unlocking the first matching part and the second matching part and increasing the elastic deformation amount of the second matching part, the first direction displacement The second direction displacement In the above, during the process of unlocking the first matching part and the second matching part and increasing the elastic deformation amount of the second matching part, the door body 3 has a tendency to move inwardly and rearwardly, which speeds up the separation of the first matching part and the second matching part, reduces the acting force of the first matching part on the second matching part, reduces the elastic deformation amount 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.

[0315] In some embodiments of the present application, during the process of unlocking the first fitting part and the second fitting part from the locked state and continuously increasing the elastic deformation amount of the second fitting part, the center point I of the shaft moves towards the side close to the plane where the second body side wall and the taking and placing opening are located. In the above, during the process of unlocking the first fitting part and the second fitting part and continuously increasing the elastic deformation amount of the second fitting part, the door body 3 has a tendency to move inwards and backwards, which accelerates the separation of the first fitting part and the second fitting part, reduces the acting force of the first fitting part on the second fitting part, reduces the elastic deformation amount of the second fitting part, facilitates the unlocking of the first fitting part and the second fitting part, and is beneficial to the unlocking of the door body and the box body.

[0316] It should be noted that the process of unlocking the first fitting part and the second fitting part from the locked state and continuously increasing the elastic deformation amount of the second fitting part includes the moment when the elastic deformation amount of the second fitting part reaches the maximum.

[0317] In some embodiments of the present application, the door body 3 is opened from the locked state of the first fitting part and the second fitting part, and the second fitting part is elastically deformed as the door body 3 is opened. During the process of gradually releasing the elastic energy stored by the elastic deformation of the second fitting part, the second shaft 6 moves relative to the guide part 7 to the position where the distance between the second shaft 6 and the taking and placing opening is the largest.

[0318] It should be noted that the process of gradually releasing the elastic energy stored by the elastic deformation of the second fitting part includes the moment when the elastic deformation amount of the second fitting part reaches the maximum.

[0319] In the above, during the process of unlocking the first fitting part and the second fitting part, after the elastic deformation amount of the second fitting part reaches the maximum, the interaction force between the first fitting part and the second fitting part rapidly decreases, and the external force required also rapidly decreases. However, the external force applied by the user cannot be rapidly reduced, or the inertial force of the door body opening still exists, which causes the relative movement speed of the first fitting part and the second fitting part to rapidly increase. At this time, the second shaft 6 moves relative to the guide part 7 to the position where the distance between the second shaft 6 and the taking and placing opening is the largest. Based on the guide track S being convex towards the side away from the plane where the taking and placing opening is located, the second shaft 6 has resistance when moving relative to the guide part 7 towards the side close to the first body side wall or away from the first body side wall. The second shaft 6 located at the position where the distance between the second shaft 6 and the taking and placing opening is the largest is in a relatively stable state relative to the guide part 7, and the movement of the door body 3 relative to the box body 1 is in a stable state, so that the unlocking process of the first fitting part and the second fitting part is more stable and smooth.

[0320] In some embodiments of the present application, when the door body 3 is closed to the angle G0, the second fitting part is locked with the first fitting part.

[0321] The door body 3 is opened from the angle G0, the first fitting part and the second fitting part interact, and the second fitting part is elastically deformed.

[0322] When the door body 3 is opened to an angle G B1 Then, the second matching part releases the stored elastic energy after elastic deformation.

[0323] When the door body 3 is opened from an angle G0 to an angle G1, the second shaft 6 moves relative to the guide part 7 to the side close to the first body side wall and away from the taking and placing opening;

[0324] When the door body 3 is opened from an angle G1 to an angle G2, the second shaft 6 moves relative to the guide part 7 to the side close to the first body side wall and the plane where the taking and placing opening is located; wherein G0 B1 <G1<G2, or G0<G1<G B1 <G2;

[0325] Wherein, the absolute value of the difference between G1 and G B1 is denoted as |G1-G B1 |, 0°≤|G1-G B1 |≤3°. When the door body 3 is opened to an angle G1, the second center shaft P is located at the first guide point P1 on the guide trajectory line S farthest from the plane where the taking and placing opening is located. Correspondingly, the second shaft 6 is located at the place on the guide part 7 farthest from the plane where the taking and placing opening is located. Based on the fact that the guide trajectory line S is convex to the side away from the plane where the taking and placing opening is located, the second shaft 6 has resistance when moving relative to the guide part 7 to the side close to or away from the first body side wall. The second shaft 6 located at the place on the guide part 7 farthest from the plane where the taking and placing opening is located 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.

[0326] When the door body 3 is opened, the first matching part and the second matching part are unlocked, and a relatively 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, which leads to 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.

[0327] The above setting of 0°≤|G1-G B1 |≤3° makes the second shaft 6 keep stable movement relative to the guide part 7 when the first matching part and the second matching part are unlocked, so that the unlocking process of the first matching part and the second matching part is more stable and smooth.

[0328] |G1-G B1 |>3°, the maximum deformation angle G B1The difference between the stable angle G1 of the second shaft 6 relative to the guide portion 7 and the stable angle G2 of the first shaft 5 relative to the guide portion 8 is too large, the unlocking process of the first matching portion and the second matching portion cannot effectively correspond to the process of the second shaft 6 relative to the guide portion 7 maintaining stable movement, and the cooperation of the second shaft 6 and the guide portion 7 cannot play a role in stabilizing the unlocking process of the first matching portion and the second matching portion.
