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 connecting 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] The refrigerator with the above hinge assembly is usually provided with a locking assembly to lock the door body and the box body when the door body is closed. The locking assembly includes a first matching part and a second matching part. When the door body is opened, the first matching part and the second matching part are unlocked, and a large external force needs to be applied to make the second matching part elastically deform under the action of the first matching part. After the elastic deformation amount of the second matching part reaches the maximum, the first matching part and the second matching part are separated to complete the unlocking. The unlocking process of the above second matching part with the increasing elastic deformation amount needs a large external force, and it is difficult for the first matching part and the second matching part to be separated, and the unlocking process is long. SUMMARY

[0004] The refrigerator provided by the present application is provided with a locking assembly. When the first matching part and the second matching part of the locking assembly are unlocked, the center point I of the shaft moves to the side close to the plane where the second body side wall and the taking and placing opening are located, so that the door body has a tendency to move inward and backward, the separation of the first matching part and the second matching part is accelerated, the acting force of the first matching part on the second matching part is reduced, and the unlocking of the first matching part and the second matching part is facilitated.

[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;

[0008] 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:

[0009] A first hinge member is arranged on the box body and close to the first body side wall; the first hinge member comprises:

[0010] A hinge plate is connected to the box body;

[0011] A first shaft and a guide part are arranged on the hinge plate;

[0012] A second hinge member is arranged on the door body; the second hinge member comprises:

[0013] A second shaft is matched with the guide part;

[0014] A guide part is matched with the first shaft;

[0015] A locking assembly is used to lock the door body and the box body in a closed state; the locking assembly comprises:

[0016] A first matching part is arranged on the box body close to the lower end of the door body;

[0017] A second matching part is arranged on the lower end of the door body; the first matching part and the second matching part are matched to realize the locking and unlocking of the door body and the box body;

[0018] When the door body is opened from the state that the door body is locked by the first matching part and the second matching part, the first matching part and the second matching part interact, and the second matching part is elastically deformed;

[0019] In the projection of the plane where the top wall of the box body is located, the midpoint of the line segment PQ is denoted as the shaft center midpoint I;

[0020] During the process that the first matching part and the second matching part are unlocked from the locked state and the elastic deformation amount of the second matching part is continuously increased, the shaft center midpoint I moves to the side close to the second body side wall and the plane where the taking and placing opening is located.

[0021] In the above technical solution, during the process that the first matching part and the second matching part are unlocked and the elastic deformation amount of the second matching part is increased, the shaft center midpoint I moves to the side close to the second body side wall and the plane where the taking and placing opening is located, so that the door body has a tendency to move inwardly and rearwardly, the separation of the first matching part and the second matching part is accelerated, the acting force of the first matching part on the second matching part is reduced, and the unlocking of the first matching part and the second matching part is facilitated.

[0022] In some embodiments, the door body has a door front wall away from the box body when the door body is closed, a door side wall connected to the door front wall and located away from the second body side wall of the door body;

[0023] When the door body is in the closed state, the first shaft is located at one end of the guide portion away from the door side wall, and the second shaft is located at one end of the guide portion close to the first body side wall.

[0024] In the technical solution, the positions of the first shaft relative to the guide portion and the second shaft relative to the guide portion when the door body is closed are limited, so as to limit 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 limiting the translation 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 extrusion of the door body on the door seal.

[0025] In some embodiments, the guide portion extends from one end thereof away from the first body side wall to one side close to the first body side wall and away from the plane of the taking and placing opening, and then extends to one side close to the first body side wall and the plane of the taking and placing opening.

[0026] During the opening of the door body, the second shaft makes reciprocating motion relative to the guide portion.

[0027] In the technical solution, the extension trend of the guide portion is limited, and the extension trend of the guide portion is divided into two sections, and the trajectory extension trend is simple, thereby improving the smoothness of the motion of the second shaft relative to the guide portion.

[0028] In some embodiments, the guide portion extends from one end thereof away from the door side wall to one side close to the door side wall and away from the front wall of the door, and then extends to one side close to the door side wall and the front wall of the door.

[0029] During the opening of the door body, the first shaft makes unidirectional motion relative to the guide portion.

[0030] In the technical solution, the extension trend of the guide portion is limited, and the extension trend of the guide portion is divided into two sections, and the trajectory extension trend is simple, thereby improving the smoothness of the motion of the first shaft relative to the guide portion.

[0031] In some embodiments, the first shaft is located at one side of the guide portion away from the first body side wall, and the second shaft is located at one side of the guide portion close to the front wall of the door.

[0032] In the 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.

[0033] In some embodiments, the door body is opened in the locked state of the first cooperating portion and the second cooperating portion, and as the door body continues to be opened, the second cooperating portion is elastically deformed.

[0034] In the process of gradually releasing the elastic energy stored by the elastic deformation of the second matching part, the second shaft moves to a position where the distance between the second shaft and the plane where the taking and placing opening is located is the largest relative to the guide part.

[0035] In the above technical solution, 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 quickly reduced, or the inertial force of the door body opening still exists, resulting in a rapid increase in the relative movement speed of the first matching part and the second matching part. At this time, the second shaft keeps stable movement relative to the guide part, so that the unlocking process of the first matching part and the second matching part is more stable and smooth.

[0036] In some embodiments, when the door body is closed to an angle G0, the second matching part is locked with the first matching part;

[0037] The door body is opened from the angle G0, the first matching part and the second matching part interact, and the second matching part is elastically deformed;

[0038] When the door body is opened to an angle G B1 , the elastic deformation of the second matching part releases the stored elastic energy;

[0039] When the door body is opened to an angle G1, the second shaft moves to a position where the distance between the second shaft and the plane where the taking and placing opening is located is the largest on the guide part;

[0040] Wherein, the absolute value of the difference between G1 and G B1 is denoted as |G1-G B1 |, and 0°≤|G1-G B1 |≤3°.

[0041] In the above technical solution, 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 quickly reduced, or the inertial force of the door body opening still exists, resulting in a rapid increase in the relative movement speed of the first matching part and the second matching part. At this time, the second shaft keeps stable movement relative to the guide part, so that the unlocking process of the first matching part and the second matching part is more stable and smooth.

[0042] In some embodiments, the movement trajectory of the center axis of the first shaft relative to the guide part is denoted as a guide trajectory line F, and the guide trajectory line F protrudes away from the front wall of the door body;

[0043] The point farthest from the door front wall on the guide trajectory line F is denoted as a third guide point H;

[0044] In a planar projection parallel to the cabinet top wall, along a direction perpendicular to the door side wall, a distance between the center axis of the second shaft and the third guide point H is denoted as |PH|2; and 0mm≤|PH|2≤5mm.

[0045] 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 center axis and the third guide point H on the guide trajectory line is too large; in the process of movement of the door body relative to the cabinet, when the first center axis Q moves to the third guide point H, the distance between the second center axis and the first center axis in the direction perpendicular to the door side wall is too large, and the 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 relative to the cabinet is poor.

[0046] In the present application, 0mm≤|PH|2≤5mm is provided, in the direction perpendicular to the door side wall, the second center axis is close to the third guide point H on the guide trajectory line which is farthest from the door front wall; in the process of movement of the door body relative to the cabinet, when the first center axis Q moves to the third guide point H, in the direction perpendicular to the door side wall, the second center axis is close to the first center axis, effectively ensuring the stability of the movement of the door body relative to the cabinet.

[0047] In some embodiments, the point farthest from the door side wall and closest to the door front wall on the guide trajectory line F is denoted as a first guide point K;

[0048] In a planar projection parallel to the cabinet top wall, along a direction perpendicular to the door front wall, a distance between the center axis of the second shaft and the first guide point K is denoted as |PK|1; and 0mm≤|PK|1≤3mm.

[0049] In the above technical solution, when 3mm<|PK|1, |PK|1 is too large, in the direction perpendicular to the door front wall, the distance between the second center axis P and the first guide point K on the guide trajectory line which is farthest from the door side wall is too large; in the process of movement of the door body relative to the cabinet, when the first center axis Q is located to the first guide point K, the distance between the second center axis and the first center axis in the direction perpendicular to the door front wall 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 relative to the cabinet is poor.

[0050] 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 track line which is farthest from the door side wall; during the movement of the door body relative to the cabinet, when the door body is closed, the first center shaft Q is located at the first guide point K, and in the direction perpendicular to the door side wall, the second center shaft P is close to the first center shaft, thereby effectively ensuring the stability of the movement of the door body relative to the cabinet.

[0060] a guide portion cooperating with the first shaft;

[0061] a locking assembly locking the door body and the cabinet in a closed state; the locking assembly comprises:

[0062] a first cooperating portion arranged on the cabinet close to the lower end of the door body;

[0063] a second cooperating portion arranged on the lower end of the door body, the first cooperating portion and the second cooperating portion cooperating to realize locking and unlocking of the door body and the cabinet;

[0064] when the door body is opened by the first cooperating portion and the second cooperating portion in the locked state, the first cooperating portion and the second cooperating portion interact, and the second cooperating portion is elastically deformed;

[0095] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

[0096] 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.

[0097] Among them, referring to Figure 1 The direction in which the bottom wall of the cabinet 1 points to the top wall 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.

[0098] 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 (the rear wall of the cabinet 1) of the cabinet 1 opposite to the taking and placing opening.

[0099] In some embodiments of the present application, the plurality of receiving cavities can include a refrigeration chamber and a freezing chamber to form receiving cavities of different temperatures to store different articles.

[0100] 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 to the cabinet 1, so that the door body 3 can rotate relative to the cabinet 1 to open or close the taking and placing opening.

[0101] The door 3 has a front wall 31 that is away from the housing 1 when the door 3 is closed, a rear wall 32 that is opposite to the front wall 31, and a side wall 33 that is close to the first body side wall and connected to the front wall 31. For example, when the hinge assembly is located on the right side of the housing 1, the right side wall of the door 3 is the side wall 33. When the hinge assembly is located on the left side of the housing 1, the left side wall of the door 3 is the side wall 33. It should be noted that the front wall 31 is the foremost surface of the door 3 when it is closed. When the door 3 includes a glass panel located on its front side when it is closed, the front wall 31 is the foremost surface of the glass panel. The rear wall 32 is the surface closest to the rear side when the door 3 is closed. When the door 3 is closed, the distance between the front wall 31 and the plane where the access opening is located is the largest, and the distance between the rear wall 32 and the plane where the access opening is located is the smallest.

[0102] In some embodiments of this application, the door sidewall 33 is connected to the door frontwall 31 and is close to the pivot axis of the door body 3. The pivot axis of the door body 3 is close to the first body sidewall.

[0103] The front wall 31 and the side wall 33 of the door 3 intersect to form a first side edge W, and the side wall 33 intersects with the rear wall 32 to form a second side edge N. When the door 3 is closed, the first side edge W is located on the side of the second side edge N that is away from the box 1.

[0104] It should be noted that when both the front wall 31 and the side wall 33 are flat surfaces, the intersection line of the plane containing the front wall 31 and the plane containing the side wall 33 is the first side edge W. When the intersection of the front wall 31 and the side wall 33 is rounded, a radius is formed along the height direction of the door body 3 (i.e., as shown in the image). Figure 1 The curved surface extends along the height direction shown in the figure. For ease of description, any straight line extending along the height direction of the door body 3 on this curved surface represents the first side edge W. Similarly, the corners at the intersection of the rear wall 32 and the side wall 33 are rounded, and the intersection line of the planes of the rear wall 32 and the side wall 33 can be used to represent the second side edge N, or a straight line that is close to and parallel to the intersection line can be used to represent the second side edge N.

[0105] In some embodiments of this application, a door seal is provided on the rear wall 32 of the door body 3. When the door body 3 closes the access opening, the door seal surrounds the access opening to effectively seal it. When the door body 3 is closed, the door seal fits against the front end face of the housing 1 to effectively seal the connection between the door body 3 and the housing 1, thereby ensuring that the door body 3 seals the access opening and preventing cold air from escaping.

[0106] In this application, the use of This indicates the opening angle of door 3.

[0107] In some embodiments of this application, the opening angle of the door 3 is... The door front wall 31 is parallel to the plane of the access opening.

[0108] In some embodiments of the present application, the opening angle of the door body 3 The door rear wall 32 is perpendicular to the plane of the access opening.

[0109] In some embodiments of the present application, the opening angle of the door body 3 The door side wall 33 is parallel to the plane of the access opening.

[0110] In some embodiments of the present application, the opening angle of the door body 3 The opening angle of the door body 3 when the door body 3 is opened relative to the cabinet 1 to open the access opening is positive.

[0111] The door body 3 is moved in the closing direction from When the door body 3 is further pressed, the opening angle of the door body 3 is negative.

[0112] In some embodiments of the present application, the opening angle of the door body 3 is recorded as a closing state.

[0113] In some embodiments of the present application, the opening angle of the door body 3 when the door body 3 is in a closing state is greater than 0, i.e. the deformation of the door seal strip when the door body 3 is in a closing state is greater than 0. 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

[0114] In some embodiments of the present application, the hinge assembly comprises a first hinge member and a second hinge member, the first hinge member cooperates with the second hinge member and can rotate relative to the second hinge member, so that the door body 3 and the cabinet 1 can rotate relative to each other.

[0115] In some embodiments of the present application, the first hinge member is arranged on the cabinet 1 and close to one of the body side walls; in this embodiment, the first hinge member close to the first body side wall is taken as an example for description. The second hinge member is arranged on the end of the door body 3 close to 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.

[0116] Referring to Figures 2 to 4 , the first hinge member comprises a hinge plate 4. Specifically, the hinge plate 4 comprises 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.

[0117] In some embodiments of the present application, the first hinge member comprises a first shaft 5 and a guide portion 7. Both the first shaft 5 and the guide portion 7 are connected to the cabinet 1.

[0118] 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 body side wall. The above arrangement makes the first shaft 5 and the guide portion 7 arranged along the width direction of the cabinet 1, reducing the space occupation along the front-back direction of the cabinet 1, and making the structure of the first hinge member more compact.

[0119] The second hinge member comprises 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 door front wall 31.

[0120] 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 a certain distance along at least the width direction of the cabinet 1 while rotating to open the taking and placing opening.

[0121] The center axis of the first shaft 5 is denoted as the first center axis Q. The center axis of the second shaft 6 is denoted as the second center axis P. When the door body 3 is opened, the trajectory line of the second center axis P moving relative to the guide portion 7 is denoted as the guide trajectory line S.

[0122] In some embodiments of the present application, the guide trajectory line S is a curve. The curved guide trajectory line S protrudes away from the plane where the taking and placing opening is located. That is, the guide trajectory line S extends from the end thereof away from the first body side wall to 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 to the side close to the first body side wall and the plane where the taking and placing opening is located. The extension trend of the above guide trajectory line S is divided into two sections, and the trajectory extension trend is simple, improving the smoothness of the movement of the second shaft relative to the guide portion.

[0123] In some embodiments of the present application, the guide trajectory line S is a circular arc, so that the movement of the second shaft 6 relative to the guide portion 7 is more smooth.

[0124] In some embodiments of the present application, the guide portion 7 is arranged as a guide groove. The guide groove is a continuous curved groove, and the curved groove protrudes away from the plane where the taking and placing opening is located.

[0125] In some embodiments of the present application, the guide groove is a circular arc groove.

[0126] In some embodiments of the present application, the guide groove comprises a guide groove bottom, a circumferential guide groove wall surrounding the guide groove bottom, and a guide groove opening defined by the circumferential guide groove wall and arranged opposite to the guide groove bottom. The second shaft 65 penetrates into the guide groove through the guide groove opening. The circumferential side wall of the second shaft 65 cooperates with the circumferential guide groove wall of the guide groove to guide the second shaft 65 when the second shaft 65 moves relative to the guide groove. The above arrangement guides the second shaft 6 through the circumferential guide groove wall of the guide groove, and the relative movement is more stable.

[0127] In some embodiments of the present application, the guide groove comprises 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.

[0128] Referring to Figure 5 In some embodiments of the present application, the center of the circular arc-shaped guide trajectory line S is denoted as a guide center O. The guide center O is located on the side of the guide trajectory line S close to the plane where the taking and placing opening is located. The radius of the circular arc-shaped guide trajectory line S is denoted as a guide radius R.

[0129] In some embodiments of the present application, 8mm≤R≤12mm.

[0130] When R<8mm, the guide radius R is too small, the curvature of the guide trajectory line S is too large, and the movement speed of the second shaft 6 relative to the guide portion 7 changes too fast.

[0131] When 12mm

[0132] When 8mm≤R, the curvature of the guide trajectory line S is prevented from being too large to cause the movement speed of the second shaft 6 relative to the guide portion 7 to change too fast, thereby improving the stability of the movement of the door body 3 relative to the cabinet 1.

[0133] When R≤12mm, the movement speed of the second shaft 6 relative to the guide portion 7 is prevented from being too small due to the guide trajectory line S being too small, thereby preventing the length of the guide trajectory line from being too long, reducing the space occupied by the guide portion 7 on the hinge plate 4, preventing the strength of the hinge plate 4 from being reduced, and ensuring the service life of the hinge assembly.

[0134] The setting of 8mm≤R≤12mm makes the movement of the second shaft 6 relative to the guide portion 7 more stable, thereby improving 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 in the hinge plate 4 is limited to ensure the strength of the hinge plate 4 and the guide portion 7, thereby effectively ensuring the service life of the hinge assembly.

[0135] In the projection of the cabinet 1 on the plane of the top wall, the guide center O is located on the side of the first central axis Q away from the plane of the taking and placing opening and the first body side wall.

[0136] In some embodiments of the present application, the maximum point of the distance between the guide trajectory line S and the plane of the taking and placing opening is denoted as a first guide point P1. The first central axis Q is located on the side of the first guide point P1 away from the plane of the taking and placing opening and close to the first body side wall.

[0137] In some embodiments of the present application, when the door body 3 is opened to an angle , the distance between the second central axis P and the first body side wall is minimum. At this time, the second central axis P is located at the first limit guide point P1` of the guide trajectory line S.

[0138] When the door body 3 is opened to an angle , the distance between the second central axis P and the first body side wall is maximum. At this time, the second central axis P is located at the second limit guide point P2` of the guide trajectory line S.

[0139] In some embodiments of the present application, in the projection of the cabinet 1 on the plane of the top wall, the distance between the first central axis Q and the first guide point P1 in the direction perpendicular to the plane of the taking and placing opening is denoted as |QP1|1; the distance between the first central axis Q and the first limit guide point P1` is denoted as |QP1`|1; and the distance between the first central axis Q and the second limit guide point P2` is denoted as |QP2`|1.

[0140] In some embodiments of the present application, in the projection of the cabinet 1 on the plane of the top wall, the first guide point P1, the first limit guide point P1` and the second limit guide point P2` are all located on the side of the first central axis Q away from the plane of the taking and placing opening. That is, the trajectory segment of the guide trajectory line 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 central axis Q away from the plane of the taking and placing opening.

[0141] In some embodiments of the present application, |QP1`|1≤|QP1|1 and |QP2`|1≤|QP1|1. However, |QP1|1≠|QP1`|1 and |QP1|1≠|QP2`|1 do not hold at the same time.

[0142] In some embodiments of the present application, 0mm≤|QP1|1≤4mm.

[0143] When 4mm < |QP1|1, the second shaft 6 moves to the position where the distance between the guide portion 7 and the plane of the access opening is the largest, and the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane of the access opening is too large, which causes the displacement of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane of the access opening to be too large, and causes the movement of the door body 3 relative to the cabinet 1 in the width direction to be unbalanced with the movement 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.

[0144] 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 of the access opening is the largest, and the second shaft 6 is close to the first shaft 5 in the direction perpendicular to the plane of the access opening, which effectively controls the displacement of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane of the access opening, and controls the movement of the door body 3 relative to the cabinet 1 in the width direction to be balanced with the movement 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.

[0145] In some embodiments of the present application, 0mm≤|QP1`|1≤2mm.

[0146] When 2mm < |QP1`|1, the second shaft 6 moves to the position where the distance between the guide portion 7 and the first body side wall is the smallest, and the distance between the second shaft 6 and the first shaft 5 in the direction perpendicular to the plane of the access opening is too large, which causes the displacement of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane of the access opening to be too large, and causes the movement of the door body 3 relative to the cabinet 1 in the width direction to be unbalanced with the movement 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.

[0147] In the present application, the setting of 0mm≤|QP1`|1≤2mm makes the second shaft 6 move to the position where the distance between the guide portion 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 of the access opening, which effectively controls the displacement of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane of the access opening, and controls the movement of the door body 3 relative to the cabinet 1 in the width direction to be balanced with the movement 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.

[0148] In some embodiments of the present application, 0mm≤|QP2`|1≤3mm.

[0149] When 3mm≤|QP2`|1, the second shaft 6 moves to the position where the distance between the guide portion 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 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 unbalanced, which cannot effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0150] In the present application, the setting of 0mm≤|QP2`|1≤3mm makes the second shaft 6 move to the position where the distance between the guide portion 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, 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, 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.

[0151] The above limitations of 0mm≤|QP1|1≤4mm, 0mm≤|QP1`|1≤2mm, and 0mm≤|QP2`|1≤3mm collectively define the overall trend of the guide trajectory line S, so that the second shaft 6 is close to the first shaft 5 throughout the opening process of the door body 3 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, 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, enables the total displacement of each stage to meet the requirements of each stage during the opening process of the door body 3, 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.

[0152] In some embodiments of the present application, 20°≤∠P1`OP2`≤30°.

[0153] When ∠P1`OP2`<20°, ∠P1`OP2` is too small, the length of the guide trajectory line 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 high when the second shaft 6 moves relative to the guide portion 7, which increases the wear of the second shaft 6 and the guide portion 7 and reduces the service life of the hinge assembly.

[0154] When 30°<∠P1`OP2`, ∠P1`OP2` is too large, the length of the guide trajectory line 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, and reduces the service life of the hinge assembly.

[0155] When 20°≤∠P1`OP2`, the length of the guide trajectory line is limited within a reasonable range, the relative friction times of the second shaft 6 relative to the guide portion 7 is limited, the abrasion of the second shaft 6 and the guide portion 7 is reduced, and the service life of the hinge assembly is ensured.

[0156] When ∠P1`OP2`≤30°, the length of the guide trajectory line is limited within a reasonable range, the space occupation of the guide portion 7 to the hinge plate 4 is reduced, the strength of the hinge plate 4 is avoided to be reduced, and the service life of the hinge assembly is ensured.

[0157] When 20°≤∠P1`OP2`≤30°, the length of the guide trajectory line (the guide portion 7) is limited, on the one hand, the relative friction times of the second shaft 6 relative to the guide portion 7 is reduced to reduce the abrasion of the second shaft 6 and the guide portion 7; on the other hand, the space occupation of the guide portion 7 to the hinge plate 4 is reduced, the strength of the hinge plate 4 is avoided to be reduced, and the service life of the hinge assembly is ensured.

[0158] In some embodiments of the present application, 12°≤∠P1`OP1≤20°.

[0159] The stroke of the second shaft 6 relative to the guide portion 7 moving between the first guide point P1 and the first limit guide point P1` is recorded as the first stroke.

[0160] When ∠P1`OP1<12°, ∠P1`OP1 is too small, the first stroke of the second shaft 6 relative to the guide portion 7 moving between the first guide point P1 and the first limit guide point P1` is too small, 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 appropriately the first stroke which is too small, and the restriction of the space of the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0161] When 20°<∠P1`OP1, ∠P1`OP1 is too large, during the process of the second shaft 6 relative to the guide portion 7 moving 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, which leads to that at least one segment 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 which 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 of the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0162] When 12°≤∠P1`OP1, the first stroke of the second shaft 6 relative to the guide portion 7 moving between the first guide point P1 and the first limit guide point P1` meets the movement demand of the door body 3, 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 appropriately the first stroke which meets the movement demand of the door body 3, and the restriction of the space of the cabinet 2 on the movement of the door body 3 can be effectively reduced.

[0163] When ∠P1`OP1≤20°, in the process of the second shaft 6 moving relative to the guide part 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 where the taking and placing opening is located, the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front and 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.

[0164] The setting of 12°≤∠P1`OP1≤20° in the present application makes the second shaft 6 move to the guide part 7 in the process of moving 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 and back direction are appropriate, 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.

[0165] In some embodiments of the present application, 7°≤∠P2`OP1≤11°.

[0166] In the process of the second shaft 6 moving relative to the guide part 7 between the first guide point P1 and the second limit guide point P2`, the stroke is recorded as a second stroke.

[0167] When ∠P2`OP1<7°, ∠P2`OP1 is too small, the second stroke of the second shaft 6 moving relative to the guide part 7 between the first guide point P1 and the second limit guide point P2` is too small, the second stroke appropriate for the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front and 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.

[0168] When 11°<∠P2`OP1, ∠P2`OP1 is too large, in the process of the second shaft 6 moving relative to the guide part 7 between the first guide point P1 and the second limit guide point P2`, there is a case that 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 at least one segment of the movement of the door body 3 relative to the cabinet 1 has a displacement in the direction perpendicular to the plane where the taking and placing opening is located which 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 and back direction are imbalanced, so that the restriction of the space defined by the cabinet 2 on the movement of the door body 3 cannot be effectively reduced.

[0169] When 7°≤∠P2`OP1, the second stroke of the second shaft 6 moving relative to the guide part 7 between the first guide point P1 and the second limit guide point P2` meets the movement demand of the door body 3, the second stroke appropriate for the movement amount of the door body 3 relative to the cabinet 1 along the width direction and the movement amount along the front and back direction meets the movement demand 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.

[0170] When ∠P2`OP1≤11°, in the process of the second shaft 6 moving relative to the guide part 7 between the first guide point P1 and the second limit guide point P2`, 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, 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 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.

[0171] 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`, 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 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.

[0172] In some embodiments of the present application, 1.6≤∠P1`OP1: ∠P2`OP1≤2.

[0173] When ∠P1`OP1: ∠P2`OP1<1.6, ∠P1`OP1: ∠P2`OP1 is too small, the first stroke is too small, the appropriate first stroke of 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 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 allocation of the first stroke and the second stroke 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.

[0174] 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 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 3 relative to the cabinet 1 has a displacement amount in the direction perpendicular to the plane where the taking and placing opening is located that 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 in the front-back direction are unbalanced, 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 allocation of the first stroke and the second stroke 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.

[0175] When 1.6≤∠P1`OP1:∠P2`OP1, the first stroke meets the movement requirement of the door body 3, 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 within the first stroke, which meets the movement requirement of the door body 3, 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 during movement, which can meet the displacement requirement of the door body 3 in each stage of opening.

[0176] 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 during movement, which can meet the displacement requirement of the door body 3 in each stage of opening.

[0177] In this 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 in the front-back direction appropriate during the movement of the first stroke, and the stroke appropriately meets the movement requirement 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 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 during movement, which can meet the displacement requirement of the door body 3 in each stage of opening.

[0178] In the projection of the plane of the top wall of the cabinet 1, the distance between the first center shaft Q and the center O of the guide circle in the direction perpendicular to the plane of the taking and placing opening is denoted as |QO|1. 3≤|QO|1: |QP1|1.

[0179] When |QO|1: |QP1|1<3, |QO|1: |QP1|1 is too small, when the second shaft 6 moves to the position where the distance between the guide part 7 and the plane of the taking and placing opening is the largest, 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 the displacement amount 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, 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 unbalanced, which cannot effectively reduce the restriction of the space defined by the cabinet 2 on the movement of the door body 3.

[0180] 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 of the taking and placing opening when the second shaft 6 moves to the position where the distance between the guide part 7 and the plane of the taking and placing opening is the largest, effectively controls the displacement amount of the door body 3 relative to the cabinet 1 in the direction perpendicular to the plane of the taking and placing opening, 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, 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.

[0181] With reference 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 movement of the first central axis Q relative to the guide part 8 is denoted as a guide trajectory line F.

[0182] 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.

[0183] 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 central axis P first decreases and then increases.

[0184] In some embodiments of the present application, the guide trajectory line F includes a second 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 the door front wall 31.

[0185] In some embodiments of the present application, the distance between one end of the second guide segment away from the door side wall 33 and the second central axis P first increases and then decreases.

[0186] In some embodiments of the present application, the guide trajectory line F includes the first guide segment and the second guide segment connected thereto. The guide trajectory line F extends from one 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 that defines the trajectory of the movement of the central axis of the first shaft relative to the guide part is divided into two segments, the trajectory extension trend of which is simple, and the movement fluency of the first shaft relative to the guide part is improved.

[0187] 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 the side away from the door front wall 31. The guide trajectory line F includes the first guide segment and the second guide segment connected to one end of the first guide segment close to the door side wall 33. Specifically, the guide trajectory line F 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 first, and then extends to a side close to the door side wall 33 and the door front wall 31.

[0188] In some embodiments of the application, the distance between the end of the guide trajectory F far from the door side wall 33 and the door front wall 31 is less than the distance between the end of the guide trajectory F close to the door side wall 33 and the door front wall 31.

[0189] In some embodiments of the application, the point of the guide trajectory F far from the door side wall 33 and closest to the door front wall 31 is denoted as the first guide point K. The point of the guide trajectory F close to the door side wall 33 and closest to the door front wall 31 is denoted as the second guide point J. The point of the guide trajectory F farthest from the door front wall 31 is denoted as the third guide point H.

[0190] Corresponding to the guide portion 8, the point of the guide portion 8 far from the door side wall 33 and closest to the door front wall 31 is denoted as the first guide boundary point K`. The point of the guide portion 8 close to the door side wall 33 and closest to the door front wall 31 is denoted as the second guide boundary point J`. The point of the guide portion 8 farthest from the door front wall 31 is denoted as the third guide boundary point H`.

[0191] 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.

[0192] In some embodiments of the 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 passing through the first guide boundary point K` and the first guide point K is perpendicular to the door front wall 31.

[0198] 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.

[0199] 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.

[0200] 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.

[0201] 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 it has 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 it has no necessary relationship with the parallel relationship with the door front wall 31.

[0202] Reference 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.

[0203] When 5mm < |PH| 2, |PH| 2 is too large, in the direction perpendicular to the door side wall 33, the distance between the second axis 6 and the third guide point H on the guide track line farthest from the door front wall 31 is too large; during 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 where the first center axis and the second center axis are located relative to the plane where the taking and placing 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.

[0204] In the present application, the setting of 0mm≤|PH| 2≤5mm, in the direction perpendicular to the door side wall 33, the second axis 6 is close to the third guide point H on the guide track line farthest from the door front wall 31; during 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.

[0205] Reference Figure 6 In the planar projection parallel to the top wall of the cabinet 1, in the direction perpendicular to the door front wall 31, the distance between the second center axis P and the first guide point K is denoted as |PK| 1. Wherein, 0mm≤|PK| 1≤3mm.

[0206] When 3mm < |PK| 1, |PK| 1 is too large, in the direction perpendicular to the door front wall 31, the distance between the second center axis P and the first guide point K on the guide track line farthest from the door side wall 33 is too large; during the movement of the door body 3 relative to the cabinet 1, when the first center axis Q is located to the first guide point K, the distance between the second center axis and the first center axis in the direction perpendicular to the door front wall 31 is too large, and the 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 located is too large, at this time, the stability of the movement of the door body 3 relative to the cabinet 1 is poor.

[0207] In the present application, the setting of 0mm≤|PK| 1≤3mm, in the direction perpendicular to the door front wall 31, the second axis 6 is close to the first guide point K on the guide track line farthest from the door side wall 33; during the movement of the door body 3 relative to the cabinet 1, when the door body 3 is closed, when the first center axis Q is located to the first guide point K, in the direction perpendicular to the door side wall 33, the second center axis P is close to the first center axis, effectively ensuring the stability of the movement of the door body 3 relative to the cabinet 1.

[0208] 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 door front wall 31.

[0209] As Figures 7-20As shown, the movement of the first shaft 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 shaft 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 second body side wall) while rotating, so as to avoid interference between the door body 3 and the cabinet 2, and ensure effective opening of the door body 3.

[0210] In some embodiments of the present application, 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 a point that dynamically changes relative to the cabinet 1 throughout the process.

[0211] In some embodiments of the present application, within the projection of the top wall of the cabinet 1, the line segment PQ is recorded as the axis center line segment PQ. The midpoint of the axis center line segment PQ is recorded as the axis center 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 a point that dynamically changes relative to the cabinet 1 (the axis center midpoint I) throughout the process. Under the above arrangement, during the opening of the door body 3, the first center axis Q moves relative to the guide trajectory line F, the second center axis P moves relative to the guide trajectory line S, and the door body 3 rotates with the axis center midpoint I as the instantaneous rotation center.

[0212] During the above 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 center line segment PQ relative to the cabinet 1 change constantly, the position of the axis center 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.

[0213] 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.

[0214] 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 more smooth.

[0215] As Figures 7-20As shown, with the first shaft 5 and the guide part 7 (the cabinet 1) on the cabinet 1 as the static reference, the movement of the second shaft 6 along the guide part 7 is equivalent to the movement of the second center axis P along the guide track line S, and the movement of the guide part 8 relative to the first shaft 5 is equivalent to the movement of the guide track line F passing through the first center axis Q, so that the door body 3 can move a distance inwards (in the direction close to 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.

[0216] 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 the 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 part 8 located on the door body 3 relative to the first shaft 5 provided on the cabinet 1 (or the movement of the second shaft 6 located on the door body 3 relative to the guide part 7 provided 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.

[0217] In the plane in which the top wall of the cabinet 1 is located, 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 in which the taking and placing opening is located, and OA is parallel to the plane in which the taking and placing opening is located (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 in which the taking and placing opening is located to the door front wall 31 of the door body 3 when the door body 3 is closed (from the back to the front) is defined as the positive direction of the B axis.

[0218] 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.

[0219] 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 in which the taking and placing opening is located (along the B axis). The movement amount of the first direction perpendicular to the direction of the first body side wall (along the A axis) is denoted as the first direction displacement The first direction displacement is inward; the first direction displacement is outward. The modulus of the first direction displacement is denoted as

[0220] The movement amount of the second direction perpendicular to the direction of the plane in which the taking and placing opening is located (along the B axis) is denoted as the second direction displacement Among them, the displacement in the second direction At that time, it has a forward displacement; a second directional displacement At that time, it has a backward displacement. Among them, the displacement in the second direction... The module is denoted as

[0221] In some embodiments of this application, the opening angle of the door 3 is: When the door is closed, the first shaft 5 is located at the end of the guide 8 away from the door side wall 33, and the second shaft 6 is located at the end of the guide 7 close to the first side wall. The positions of the first shaft relative to the guide and the second shaft relative to the guide when the door is closed are defined above to limit the movement trend of the first shaft relative to the guide and the second shaft relative to the guide during the first stage of door opening. This limits the translational trend of the door relative to the cabinet during the first stage of door opening, thus avoiding interference between the door and the cabinet and preventing or reducing door pressure on the door seal.

[0272] In some embodiments of the present application, the door body 3 is displaced by opening to In the process of opening to In the process of opening to opening to In the process of opening to

[0273] In some embodiments of the present application, the door body 3 is displaced by opening to the second direction displacement is not greater than the second direction displacement opening to In the process of opening to In the process of opening to opening to In the process of opening to opening to In the process of opening to opening to In the process of opening to The state of the door body 3 has a translational displacement amount that is overall inward and forward, so as to compensate for the displacement of the first side edge W moving outward caused by the simple rotation of the door body 3, effectively avoiding interference between the first side edge W and the cabinet 2; and simultaneously efficiently reducing the limitation of the space of the cabinet 2 on the maximum angle that the door body 3 can open in the space.

[0274] In some embodiments of the present application, the refrigerator comprises a locking assembly. The locking assembly comprises a first cooperating part and a second cooperating part that cooperate to achieve locking and unlocking of the door body 3 and the cabinet 1. The first cooperating part is arranged on the cabinet 1 near the lower end of the door body 3, and the second cooperating part is arranged on the lower end of the door body 3 to cooperate with the first cooperating part.

[0275] In some embodiments of the present application, the first cooperating part is located on the side of the first hinge member away from the first body side wall. The second cooperating part is located on the side of the second hinge member away from the door side wall 33. The second cooperating part is used to cooperate with the first cooperating part to achieve locking and unlocking of the door body 3 and the cabinet 1.

[0276] In some embodiments of the present application, the locking process of the door body 3 and the cabinet 1 is as follows:

[0277] When the door body 3 is closed from the open state, the door body 3 gradually closes. As the door body 3 rotates to close, the second cooperating part gradually approaches the first cooperating part.

[0278] When the door body 3 is closed to an angle G B0 , the second cooperating part contacts the first cooperating part. The door body 3 continues to close, the first cooperating part and the second cooperating part interact, and the second cooperating part elastically deforms. Under the joint action of external force and the force of the first cooperating part, the second cooperating part and the first cooperating part gradually approach, and the elastic deformation amount of the second cooperating part gradually increases.

[0279] When the door body 3 is closed to an angle G B2 , the elastic deformation amount of the second cooperating part reaches the maximum deformation amount in the closing process of the door body 3.

[0280] When the door body 3 continues to move in the closing direction after closing to an angle G B2 , the elastic energy stored by the elastic deformation of the second cooperating part is released, the second cooperating part returns 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 cooperating part and the first cooperating part are locked, achieving locking of the door body 3 and the cabinet 1.

[0281] Above, G B0 > G B2 .

[0282] As can be seen from the above, the door body 3 is closed from an angle G B0 to an angle G B2During the process, the amount of elastic deformation of the second mating part continuously increases.

[0283] When door 3 is closed to angle G B2 At that time, the elastic deformation of the second mating part reaches the maximum deformation during the closing process of the door body 3.

[0284] At angle G in door body 3 B2 During the process of closing, the elastic force of the second mating part is released, and the door 3 closes automatically.

[0285] That is, under the structural arrangement of the first mating part and the second mating part, the door body 3 is in the position of angle G B2 During the process of closing, door 3 has the characteristic of automatic closing. With the locking component set, door 3 can automatically close to the position to ensure a sealed fit between door 3 and housing 1, preventing cold air leakage.

[0286] In some embodiments of this application, the unlocking process between the door 3 and the box 1 is as follows:

[0287] When door 3 is opened from the closed state (or when door 3 is opened from angle G0), door 3 gradually opens. As door 3 rotates open, the second mating part interacts with the first mating part, and the second mating part undergoes elastic deformation.

[0288] As the door 3 continues to open, the elastic deformation of the second mating part gradually increases. During the continuous elastic deformation of the second mating part, a large external force needs to be applied to keep the door opening and to make the first and second mating parts separate.

[0289] When door 3 is opened to angle G B1 At that time, the elastic deformation of the second mating part reaches the maximum deformation during the opening process of the door 3.

[0290] When door 3 opens to angle G B1 Then, it continues to move in the opening direction, and the elastic energy stored in the elastic deformation of the second mating part is released, and the second mating part returns to its relaxed state. The second mating part separates from the first mating part, and the door 3 separates from the box 1.

[0291] In some embodiments of this application, when the door 3 is closed to angle G0, the second mating part locks with the first mating part.

[0292] When the door 3 is opened at angle G0, the first mating part and the second mating part interact with each other, and the second mating part undergoes elastic deformation.

[0293] When the door is opened to angle G B1 Afterwards, the elastic energy stored in the second mating part is released by elastic deformation.

[0294] That is, door 3 opens from angle G0 to angle G B1 During the process, the amount of elastic deformation of the second mating part continuously increases. When the door 3 opens to angle G... B1 At that time, the elastic deformation of the second mating part reaches the maximum deformation of the door 3 during the closing process. When the door 3 is at angle G... B1 As the opening process continues, the elastic force of the second mating part is released.

[0295] In some embodiments of this application, G B2 =G B1 .

[0296] In some embodiments of this application, the second mating part is located on the side of the second shaft 6 and the guide part 8 away from the door sidewall 33. The second mating part is configured as a locking hook. Specifically, the locking hook first extends away from the door sidewall 33, and then bends towards the side closer to the door rear wall 32 and the door sidewall 33, with the opening of the locking hook facing the door sidewall 33. The free end of the locking hook is located on the side closer to the door rear wall 32.

[0297] In some embodiments of this application, the first mating part is located on the side of the hinge plate 4 away from the side wall of the first body. The first mating part is provided as a stop. The stop has a hook gap on the side near the housing 1.

[0298] When the door 3 is closed (or G0), the free end of the locking hook is accommodated in the hook gap, and the stop is located inside the locking hook. The locking hook on the door 3 hooks onto the stop on the hinge plate 4, thereby locking the door 3 and the cabinet 1 together, preventing cold air leakage due to incomplete closure of the door 3, which would affect the refrigeration / freezing effect of the refrigerator 100. When the door 3 is opened, the locking hook deforms under force, overcoming the obstruction of the stop, and thus disengaging from the stop, thereby unlocking the door 3 and the cabinet 1.

[0299] When door 3 is opened from the closed state (or G0), it gradually opens under the action of external force. As door 3 rotates open, the free end of the locking hook interacts with the stop, causing the locking hook to undergo elastic deformation.

[0300] Then, under the action of external force, the door 3 continues to open. The stop and the lock hook interact with each other, and the lock hook undergoes elastic deformation. Under the combined action of external force and the force of the stop, the lock hook gradually disengages from the hook gap (at the same time, the stop disengages from the lock hook).

[0301] When door 3 is opened to angle G B1 At that time, the elastic deformation of the lock hook reaches the maximum deformation during the closing process of the door body 3.

[0302] When door 3 opens to angle G B1As the door continues to open, the elastic energy stored in 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 hook gap, the lock hook separates from the stop part, and the door body 3 separates from the box body 1.

[0303] In some embodiments of this application, the first mating part and the second mating part are unlocked from a locked state and the elastic deformation of the second mating part is not...

[0304] During the continuous increase, the displacement in the first direction Second directional displacement As described above, during the unlocking of the first and second mating parts and the continuous increase of the elastic deformation of the second mating part, the door 3 tends to move inward and backward, which accelerates the separation of the first and second mating parts, reduces the force of the first mating part on the second mating part, reduces the elastic deformation of the second mating part, facilitates the unlocking of the first and second mating parts, and is conducive to the unlocking of the door and the box.

[0305] In some embodiments of this application, as the first mating part and the second mating part unlock from the locked state and the elastic deformation of the second mating part continuously increases, the central point I of the axis moves towards the side closer to the plane where the second body sidewall and the pick-and-place opening are located. As the first and second mating parts unlock and the elastic deformation of the second mating part continuously increases, the door 3 tends to move inward and backward, accelerating the separation of the first and second mating parts, reducing the force exerted by the first mating part on the second mating part, reducing the elastic deformation of the second mating part, facilitating the unlocking of the first and second mating parts, and aiding in the unlocking of the door and the housing.

[0306] It should be noted that the process of the first mating part and the second mating part being unlocked from the locked state and the elastic deformation of the second mating part continuously increasing includes the moment when the elastic deformation of the second mating part reaches its maximum.

[0307] In some embodiments of this application, the door 3 is opened by the first mating part and the second mating part in a locked state. As the door 3 is opened, the second mating part undergoes elastic deformation. During the process of the elastic energy stored in the elastic deformation of the second mating part being gradually released, the second shaft 6 moves relative to the guide part 7 to the position where its distance from the take-up and put-down opening is the largest in a plane.

[0308] It should be noted that the elastic energy stored in the elastic deformation of the second mating part is gradually released during the process, including the moment when the elastic deformation of the second mating part reaches its maximum.

[0309] In the process of unlocking the first and second mating parts, after the elastic deformation of the second mating part reaches its maximum, the interaction force between the first and second mating parts decreases rapidly, and the required external force also decreases rapidly. However, the external force applied by the user cannot decrease rapidly, or the inertial force of the door opening still exists, causing the relative speed of the first and second mating parts to increase rapidly. At this time, the second shaft 6 moves relative to the guide part 7 to the position where its distance from the retrieval port is at its maximum. Since the guide trajectory line S protrudes towards the side away from the plane where the retrieval port is located, the movement of the second shaft 6 relative to the guide part 7 towards or away from the side wall of the first body is subject to resistance. The second shaft 6, located at the position where the distance from the retrieval port is at its maximum on the guide part 7, is in a relatively stable state relative to the guide part 7, and the movement of the door 3 relative to the box 1 is in a stable state, so that the unlocking process of the first and second mating parts is more stable and smooth.

[0310] In some embodiments of this application, when the door 3 is closed to angle G0, the second mating part locks with the first mating part.

[0311] When the door 3 is opened at angle G0, the first mating part and the second mating part interact with each other, and the second mating part undergoes elastic deformation.

[0312] When door 3 is opened to angle G B1 Then, the elastic energy stored in the second mating part is released by elastic deformation.

[0313] When the door 3 is opened from angle G0 to angle G1, the second shaft 6 moves relative to the guide part 7 toward the side closer to the side wall of the first body and away from the pick-up and put-out opening;

[0314] When the door 3 opens from angle G1 to angle G2, the second shaft 6 moves relative to the guide part 7 towards the side closer to the plane where the first body sidewall and the pick-up / drop-off port are located; wherein, G0 < G B1 <G1<G2, or G0<G1<G B1 <G2;

[0315] Among them, G1 and G B1 The absolute value of the difference is denoted as |G1-G B1 |,0°≤|G1-G B1|≤3°. When the opening angle of the door 3 is G1, the second central axis P is located at the first guide point P1, which is the furthest from the plane of the retrieval opening on the guide trajectory line S. Correspondingly, the second axis 6 is located at the point of maximum distance from the plane of the retrieval opening on the guide part 7. Since the guide trajectory line S protrudes towards the side away from the plane of the retrieval opening, the second axis 6 experiences resistance when moving relative to the guide part 7 towards or away from the side wall of the first body. The second axis 6, located at the point of maximum distance from the plane of the retrieval opening on the guide part 7, is in a relatively stable state relative to the guide part 7, and the movement of the door 3 relative to the box 1 is in a stable state.

[0316] When door 3 opens, a significant external force is required to unlock the first and second mating parts, causing the second mating part to elastically deform under the influence of the first mating part. After the elastic deformation of the second mating part reaches its maximum, the interaction force between the first and second mating parts decreases rapidly, and the required external force also decreases rapidly. However, if the external force applied by the user cannot decrease rapidly, or if the inertial force of door 3 still exists, the relative speed between the first and second mating parts increases rapidly. This leads to instability in the unlocking process of the first and second mating parts, resulting in unstable door 3 opening.

[0317] Above 0°≤|G1-G B1 The setting of ≤3° ensures that when the first mating part and the second mating part are unlocked, the second shaft 6 maintains a stable movement relative to the guide part 7, making the unlocking process of the first mating part and the second mating part more stable and smooth.

[0318] |G1-G B1 |>3°, the maximum deformation angle G when the first mating part and the second mating part are unlocked B1 The difference between the second shaft 6 and the stable angle G1 relative to the guide part 7 is too large. The unlocking process of the first mating part and the second mating part cannot effectively correspond to the process of the second shaft 6 maintaining stable movement relative to the guide part 7. The cooperation between the second shaft 6 and the guide part 7 cannot play a role in stabilizing the unlocking process of the first mating part and the second mating part.

At that time, the second central axis P is located at the position where the distance between the guide trajectory line S and the side wall of the first body is the greatest (second limit guide point P2` / second guide point P2).

[0321] In some embodiments of this application, the second limit guide point P2' is located on the side of the second guide point P2 that is away from the sidewall of the first body and close to the plane where the pick-up and drop-off port is located. That is, when the door 3 is opened to...

When the guide portion 7 is configured as a guide groove, the door 3 opens to... At the same time, there is a gap between the second shaft 6 and the end of the guide groove away from the side wall of the first body. The above arrangement ensures that the second shaft 6 does not collide with the end of the guide part 7 away from the side wall of the first body during the opening of the door body 3, so as to avoid the impact between the second shaft 6 and the end of the guide part 7 away from the side wall of the first body and avoid damage to the second shaft 6.

During the extension process of the guide trajectory line S, the guide trajectory line S passes through the third guide point P3. That is, the third guide point P3 is located on the guide trajectory line S and is located on the side of the second guide point P2 closer to the side wall of the first body.

[0352] In some embodiments of this application,

[0353] like Figure 10 , Figure 11 , Figure 13 , Figure 14 , Figure 15 , Figure 19 As shown, under the constraints of the aforementioned guide part 8 and the first shaft 5, and the guide part 7 and the second shaft 6, the opening process of the door 3 has a fourth stage. The fourth stage is as follows:

[0354] In some embodiments of this application, the guide trajectory line S includes a third guide point P3 and a fourth guide point P4 located on the side of the third guide point P3 near the sidewall of the first body.

[0355] The fourth guide point P4 is located on the side of the plane where the pick-up and drop-off port is located, which is close to the third guide point P3.

[0356] The guide trajectory line S extends from the third guide point P3 toward the plane close to the side wall of the first body and the pick-up / place-out port to the fourth guide point P4.
