Description

Technical Field

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

[0002] Built-in refrigerators are generally built into a customized storage cabinet. In order to improve the fit of the refrigerator in the external storage cabinet, the gap between the outer wall of the refrigerator and the inner wall of the storage cabinet is generally set to be very small. When the refrigerator door is opened, the rotating door hinge vertical edge is easy to hit the inner wall of the external storage cabinet. Due to the space limitation of the storage cabinet, in order to ensure that the door body can be opened effectively, the corner of the door body must not exceed the size of the cabinet too much during the door opening process.

[0003] At present, in order to meet the needs of embedded installation, most of them are equipped with a double shaft on one of the door and the box body, and a guide structure matched with the double shaft is arranged on the other to control the door to move inward while rotating to open, so as to meet the needs of embedded installation. Under the setting of the combination of the double shaft and the guide, the door moves inward during the opening process, so as to ensure that the corner of the door body does not exceed the size of the box body too much during the door opening process.

[0004] When customizing the storage cabinet in which the built-in refrigerator is embedded, usually, one of the standards is that when the refrigerator door is closed, the front wall of the door is flush with the plane where the opening end of the storage cabinet is located, so that the size of the refrigerator matches the size of the storage cabinet and a hidden flush installation is achieved; in addition, another standard is that the distance between the inner wall of the storage cabinet and the outer wall of the refrigerator or the side wall of the door when the door body is closed meets the minimum value for installing the refrigerator in the storage cabinet, so that the refrigerator can make full use of the installation space limited by the storage cabinet and achieve installation without / without a small gap. On the premise that the door of the built-in refrigerator can be opened smoothly without interfering with the inner wall of the storage cabinet, as the opening angle of the refrigerator door increases, the front wall of the door approaches the end of the adjacent storage cabinet near its opening; when the front wall of the door contacts the end of the adjacent storage cabinet near its opening, the door body is opened to the extreme position. In summary, the maximum opening angle of the refrigerator door installed in the storage cabinet is limited by the size of the storage cabinet for realizing the hidden installation of the refrigerator and the gap between the door side wall and the inner wall of the storage cabinet when the outer wall or door body of the refrigerator is closed. The maximum opening angle of the refrigerator door installed in the storage cabinet is small, which is inconvenient for users to take and put items. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0106] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings. In the accompanying drawings, a side of the refrigerator facing a user when in use is defined as a front side, and a side opposite thereto is defined as a rear side.

[0107] Reference Figure 1 The refrigerator includes a cabinet 10 having a storage chamber, and a door 30 connected to the cabinet 10 to open and close the storage chamber.

[0108] In some embodiments of the present application, the box body 10 defines a plurality of storage chambers for storing items. A take-out opening is formed at the front end of the storage chamber to place food into the storage chamber or take food out of the storage chamber. The refrigerator has a refrigeration device for supplying cold air to the storage chamber to store items placed in the storage chamber at low temperatures. A rotatable door body 30 is provided on the box body 10 to open or close the take-out opening of the storage chamber.

[0109] Specifically, the door body 30 is rotatably connected to the box body 10 through a hinge assembly located at the upper portion and / or a hinge assembly located at the lower portion.

[0110] In some embodiments of the present application, the hinge assembly includes a first hinge component and a second hinge component, and the first hinge component cooperates with the second hinge component and can rotate relative to each other.

[0111] The box body 10 includes a first side wall and a second side wall (i.e., a left side wall and a right side wall of the box body 10) that are arranged opposite to each other. The first hinge is arranged on the box body 10 and close to the first side wall, and the second hinge is arranged at the end of the door body 30 close to the first hinge. The first hinge cooperates with the second hinge to allow the box body 10 and the door body 30 to rotate relative to each other. The door body 30 includes a door front wall 31 that is away from the box body 10 when the door body 30 is closed, a door rear wall 33 that is arranged opposite to the door front wall 31, and a door side wall 32 that is close to the first hinge and connected to the door front wall 31. For example, when the first hinge is located on the right side of the box body 10, the right side of the door body 30 is the door side wall 32 when the door body 30 is closed. When the first hinge is located on the left side of the box body 10, the left side wall of the door body 30 is the door side wall 32 when the door body 30 is closed.

[0112] The front wall 31 and the side wall 32 of the door body 30 intersect to form a first side edge W, and the side wall 32 and the rear wall 33 intersect to form a second side edge N. When the door body 30 is closed, the first side edge W is located on the side of the second side edge N away from the box body 10 .

[0113] It should be noted that when the door front wall 31 and the door side wall 32 are both planes, the intersection line of the two planes is the theoretical first side edge W. Similarly, the theoretical second side edge N is the intersection line of the door side wall 32 and the door rear wall 33.

[0114] In actual production and processing, the intersection of the door front wall 31 and the door side wall 32 is set as a rounded transition, so that a curved surface is formed at the intersection of the door front wall 31 and the door side wall 32. On the curved surface at the intersection of the door front wall 31 and the door side wall 32, any straight line extending along the height direction of the door body 30 can be used as the first side edge W (the same applies to the second side edge N). In this application, for the convenience of description, the theoretical first side edge W and the theoretical second side edge N are used for description.

[0115] In some embodiments of the present application, a door seal 5 is provided on the door rear wall 33. When the door body 30 is closed, the door seal 5 fits with the front end surface of the box body surrounding the access opening to effectively seal the connection between the door body 30 and the box body 10, thereby ensuring that the door body 30 seals the access opening to prevent cold air from escaping. It can be provided that the door seal 5 is annular. The door seal 5 is located between the door rear wall 33 and the front end surface of the box body, and the door rear wall 33 is located on the side of the plane where the access opening of the box body 10 is located close to the door seal 5.

[0116] In some embodiments of the present application, refer to Figure 1 to Figure 2 The first hinge member includes a hinge plate 40, a first shaft 41 and a second shaft 42 provided on the hinge plate 40. The hinge plate 40 includes: a connecting portion connected to the box body 10 and close to the side wall of the first body, and an extending portion extending forward from the connecting portion. The connecting portion can be fastened to the top wall of the box body 10 by fasteners such as screws, pins and bolts. The extending portion is in the shape of a horizontal plate.

[0117] Specifically, for the hinge at the upper end of the door body 30, the connecting portion is connected to the top wall of the box body 10. For the hinge at the lower end of the door body 30, the connecting portion is connected to the front end surface of the box body 10. Among them, the first axis 41 and the second axis 42 are formed on the extension of the first hinge. The second axis 42 is located on the side of the first axis 41 away from the side wall of the first body.

[0118] The second hinge member includes: a guide portion 50 and a guide portion 60 located at the end of the door body 30 near the first hinge member. The first shaft 41 is adapted to the guide portion 50, and the second shaft 42 is adapted to the guide portion 60. When the door body 30 rotates to open or close, the first shaft 41 moves relative to the guide portion 50, and the second shaft 42 moves relative to the guide portion 60.

[0119] The first shaft 41 and the second shaft 42 are formed on the first hinge member connected to the box body 10 to form a limited axis for guiding the movement of the door body 30. Specifically, the first shaft 41 and the second shaft 42 extend in the vertical direction (the height direction of the box body 10) to adapt to the guide portion 50 or the guide portion 60 provided on the door body 30.

[0120] The built-in refrigerator is a refrigerator that is embedded as a whole in a customized storage cabinet 100. The end face of the storage cabinet 100 defining its opening is recorded as the opening end face, and the refrigerator is embedded flat in the storage cabinet 100. When the door body of the refrigerator is closed, the door front wall 31 of the door body 30 is flush with the opening end face of the storage cabinet 100. In the utility model, the first shaft 41 cooperates with the guide part 50, and the second shaft 42 cooperates with the guide part 60, so that the door body 30 moves inward by a certain distance, so that when the user opens and closes the door body 30 of the refrigerator, the door body 30 of the refrigerator will not collide with the storage cabinet 100, effectively avoiding scratches on the storage cabinet 100 or the door body of the refrigerator.

[0121] It should be noted that the "flush" in the above-mentioned flushness between the front door wall 31 and the opening end face of the storage cabinet 100 includes being on the same plane, or the distance between the two planes is not greater than 2 mm. Specifically, the front door wall 31 is located on the side of the opening end face of the storage cabinet 100 away from the access port, and the distance between the two planes is not greater than 2 mm. Or the front door wall 31 is located on the side of the opening end face of the storage cabinet 100 close to the access port, and the distance between the two planes is not greater than 2 mm.

[0122] In some embodiments of the present application, the first shaft 41 and the second shaft 42 are provided on the extensions at the upper and lower ends of the door body 30, and the guide portion 50 and the guide portion 60 are provided at the upper and lower ends of the door body 30. It should be noted that the arrangement of this embodiment is not limited to being arranged at both the upper and lower ends of the door body 30, and it is arranged as needed to connect the door body 30 and the box body 10.

[0123] In some embodiments of the present application, Figure 1-Figure 2 As shown, the plane where the side surface (first body side wall) of the box body 10 close to the hinge plate 40 is located is defined as the reference plane M0, the side of the reference plane M0 away from the inner cavity of the storage chamber is recorded as the outer side, and the opposite side close to the inner cavity of the storage chamber is recorded as the inner side.

[0124] When the refrigerator is placed in the storage cabinet 100 for use, in order to prevent factors such as uneven ground and deformation of the storage cabinet 100, when the storage cabinet 100 is set in size, the distance α' between the storage cabinet 100 and the side of the refrigerator (the first body side wall, i.e., the reference plane M0) is set. In order to ensure that the door body 30 of the refrigerator opens normally, the first side edge W of the door body 30 cannot exceed the side of the box body 10 (reference plane M0) too much during the rotation process, so as to avoid the first side edge W colliding with the storage cabinet 100 and causing the door body 30 to fail to open normally.

[0125] In some embodiments of the present application, α` is any value between 3 and 5 mm.

[0126] In some embodiments of the present application, α`=3 mm; that is, the distance between the door side wall of the door body 30 and the containing cabinet 100 is 3 mm.

[0127] To meet the above requirements, the door body 30 needs to be able to move inward during the rotation process, so that the first side edge W does not exceed the side wall (reference plane M0) of the box body 10 too much. Taking the hinge plate 40 as an example, the hinge plate 40 is arranged on the right side of the door body 30 (in this example, the right side wall of the box body 10 is the first body side wall), the inner side is the left side, that is, the door body 30 needs to be able to move to the left. Taking the hinge plate 40 as an example, the hinge plate 40 is arranged on the left side of the door body 30, the inner side is the right side, that is, the door body 30 needs to be able to move to the right.

[0128] In some embodiments of the present application, the central axis of the first axis 41 is recorded as the first central axis P, and the central axis of the second axis 42 is recorded as the second central axis Q.

[0129] In some embodiments of the present application, Figure 1 As shown, in the projection of the top wall of the box body 10, the second central axis Q is located on the side of the first central axis P away from the plane where the first body side wall and the access opening are located.

[0130] In some embodiments of the present application, in the projection of the top wall of the box 10, the second central axis Q is located on the side of the first central axis P away from the first body side wall and the access opening. The angle between the second central axis Q and the straight line QP where the first central axis P is located and the first body side wall is denoted as β.

[0131] β is not less than a first reference value. The first reference value is between 63° and 73°. The first reference value may be 63°, 68° or 73°. That is, β≥63° or β≥68° or β≥73°.

[0132] When β≥63°, the requirement that the guide portion 50 and the guide portion 60 occupy a small thickness of the door body 30 is met. When β≥68°, the requirement that the guide portion 50 and the guide portion 60 occupy a small thickness of the door body 30 is better met. When β≥73°, the requirement that the guide portion 50 and the guide portion 60 occupy a small thickness of the door body 30 is better met.

[0133] β is not greater than a second reference value. The second reference value is between 74° and 84°. The second reference value may be 74°, 79° or 84°. That is, β≤74° or β≤79° or β≤84°.

[0134] When β≤74°, the strength requirements of the guide parts 50 and 60, the first shaft 41 and the second shaft 42 are better met. When β≤79°, the strength requirements of the guide parts 50 and 60, the first shaft 41 and the second shaft 42 are better met. When β≤84°, the strength requirements of the guide parts 50 and 60, the first shaft 41 and the second shaft 42 are met.

[0135] β is too small, and the distance between the first center axis P and the second center axis Q in the direction perpendicular to the door front wall 31 is too large; the guide part 50 cooperating with the first axis 41 and the guide part 42 cooperating with the second axis 42 occupy an increased dimension in the thickness direction of the door body 30, resulting in an increase in the thickness of the door body 30, which is not suitable for an ultra-thin door body 30.

[0136] β is too large, and the distance between the first center axis P and the second center axis Q in the direction perpendicular to the front wall 31 of the door is too small; the guide portion 50 and the guide portion 60 are arranged too compactly. In order to avoid the guide portion 60 of the guide portion 50 not being cross-connected, as a way, the track width of the guide portion 50 that cooperates with the first shaft 41 and the guide portion 60 that cooperates with the second shaft 42 can be reduced, and the diameter of the first shaft 41 and the second shaft 42 needs to be reduced accordingly. Reducing the diameter of the first shaft 41 and the second shaft 42 reduces the strength of the first shaft 41 and the second shaft 42, which can easily cause the hinge assembly to be damaged and fail. As another way, the diameter of the first shaft 41 and the second shaft 42 is ensured to ensure their strength, and the minimum distance (minimum wall thickness) between the guide portion 50 and the guide portion 60 will be reduced, resulting in a reduction in the strength of the guide portion 50 and the guide portion 60.

[0137] In some embodiments of the present application, the guide portion 50 is configured as a guide groove, and the guide portion 60 is configured as a guide groove.

[0138] In some embodiments of the present application, the guide groove is a straight groove, a curved groove, or a side of the guide groove close to the first side edge W.

[0139] In some embodiments of the present application, along the direction from the door rear wall 33 to the door front wall 31 , the distance between the guide groove and the door side wall 32 gradually decreases.

[0140] In some embodiments of the present application, the trajectory line along which the guide portion 50 guides the relative movement of the first central axis P is the guide trajectory line S, and the trajectory line along which the guide portion 60 guides the relative movement of the second central axis Q is the guide trajectory line K.

[0141] The guide track line S is a straight line and is located on a side of the guide track line K close to the first side edge W.

[0142] In some embodiments of the present application, the guide trajectory line S is the center trajectory line of the guide portion 50 , and the guide trajectory line K is the center trajectory line of the guide portion 60 .

[0143] When the guide portion 50 is configured as a guide groove structure, the center trajectory line of the guide groove is the guide trajectory line S. When the guide portion 60 is configured as a guide groove structure, the center trajectory line of the guide groove is the guide trajectory line K.

[0144] In some embodiments of the present application, along a direction from an end of the door body 30 away from the door side wall 32 to the door side wall 32 , a distance between the guide track line S and the door front wall 31 gradually decreases.

[0145] Along the direction from the end of the door body 30 away from the door side wall 32 to the door side wall 32, the distance between the guide track line K and the door front wall 31 first increases, then decreases, and then increases again.

[0146] In some embodiments of the present application, the guide track line S extends from one end thereof away from the door side wall 32 to a side close to the door front wall 31 and the door side wall 32 .

[0147] The guide track line K extends from the side away from the door side wall 32 to the direction away from the door front wall 31 and close to the door side wall 32, and then extends to the side close to the door front wall 31 and the door side wall 32. The guide track line S is located on the side of the guide track line K close to the first side edge W.

[0148] In some embodiments of the present application, the guide track line K includes a first guide segment and a second guide segment connected to an end of the first guide segment close to the door side wall 32. The first guide segment extends from an end away from the door side wall 32 to a direction close to the door side wall 32 and away from the door front wall 31, and the second guide segment extends from an end of the first guide segment close to the door side wall to a direction close to the door side wall 32 and the door front wall 31. That is, the second guide segment extends from an end away from the door side wall 32 to a direction close to the door side wall 32 and the door front wall 31.

[0149] In some embodiments of the present application, Figure 2 As shown, in the projection of the plane where the top wall of the box body 10 (door body 30) is located, the door side wall 32 is the Y axis, and the plane passing through the first side edge W and perpendicular to the door side wall 32 is the X axis, that is, the plane where the door front wall 31 is located is the X axis (it can be set that the door front wall 31 is perpendicular to the door side wall 32); wherein, the X axis is perpendicular to the Y axis and intersects at the origin O (the first side edge W). The direction from the door front wall 31 to the door rear wall 33 is the positive direction of the Y axis, and the direction from the door side wall 32 to the opposite end of the door side wall 32 on the door body 30 is the positive direction of the X axis, forming a two-dimensional door body coordinate system XOY. It should be noted that the door body coordinate system XOY is a two-dimensional coordinate system that is stationary relative to the door body 30.

[0150] In the door body coordinate system XOY, the function corresponding to the guide trajectory line S in the coordinate system XOY is recorded as Y=F(X).

[0151] The first derivative of Y = F(X) is denoted by F` x , F` x > 0. Y = F (X) is a monotonically increasing function.

[0152] In some embodiments of the present application, the second-order derivative of Y=F(X) is denoted as F`` x , F`` x = 0. Y = F (X) is a linear function.

[0153] In some embodiments of the present application, in the door body coordinate system XOY, the function corresponding to the guide trajectory line K in the coordinate system XOY is recorded as Y=K(X);

[0154] Y=K(X) is a piecewise function, and the piecewise function is a continuous function; then, at each piecewise point, its left limit is equal to its right limit.

[0155] In some embodiments of the present application, in the door body coordinate system XOY, Y=K(X) is as follows:

[0156]

[0157] Wherein, X1>X2>X3>0; K1(X2)=K2(X2);

[0158] Y=K1(X) is the function of the second guide segment in the coordinate system XOY;

[0159] Y=K2(X) is a function of the first guide segment in the coordinate system XOY.

[0160] In some embodiments of the present application, when the door body 30 is in a closed state, the second axis 42 is located on a side of the first axis 41 away from the second side edge N. The guide portion 60 is located on a side of the guide portion 50 away from the first side edge W.

[0161] Since the guide portion 50 and the first shaft 41, and the guide portion 60 and the second shaft 42 are in a relative motion relationship, if the door body 30 is opened, with the guide portion 50 and the guide portion 60 as stationary reference objects, it is equivalent to the first shaft 41 moving under the restriction of the guide portion 50, and the second shaft 42 moving under the restriction of the guide portion 60. For the convenience of description, the present application adopts the guide portion 50 and the guide portion 60 as stationary reference objects, and the first shaft 41 and the second shaft 42 move relative to the stationary reference objects for description.

[0162] In some embodiments of the present application, in the projection of the plane where the top wall of the box 10 is located, the line segment PQ is recorded as the axis line segment PQ. The center of the axis line segment PQ is recorded as the axis center point I. Figure 2-Figure 16 As shown, the movement of the first axis 41 along the guide portion 50 is equivalent to the movement of the first center axis P along the guide trajectory S, and the movement of the second axis 42 along the guide portion 60 is equivalent to the movement of the second center axis Q along the guide trajectory K, so that the door body 30 can move a distance inward (in the direction close to the second body side wall) while rotating, so that the door body 30 does not interfere with the storage cabinet 100, ensuring that the door body 30 is effectively opened.

[0163] Under the above settings, when the door body 30 is opened from the first angle G1 to the ninth angle G9, the first axis 41 moves relative to the guide portion 50 throughout the entire process, the second axis 42 moves relative to the guide portion 60 throughout the entire process, and the door body 30 rotates around the point (axis center point I) that maintains dynamic changes relative to the door body 30 throughout the entire process. Under the above settings, when the door body 30 is opened, the first center axis P moves relative to the guide trajectory line S, and the second center axis Q moves relative to the guide trajectory line K, and it rotates with the axis center point I as the instantaneous rotation center, and the instantaneous rotation center of the door body 30 is the axis center point I. The position of the axis center point I relative to the door body 30 is constantly changing, and the position of the instantaneous rotation center of the door body 30 is constantly changing.

[0164] It should be noted that, different from the above configuration, only the center axis of the first shaft 41 is used as the instantaneous rotation center axis first center axis P of the rotational motion, rather than the axis center point I.

[0165] The movement of the door body 30 relative to the box body 10 is equivalent to the relative movement of the two in the plane where the top wall of the box body 10 is located (or in the plane perpendicular to the first side edge W or the second side edge N). That is, the movement of the door body 30 relative to the box body 10 can be attributed to the relative movement in a two-dimensional plane.

[0166] Since the first hinge member having the first axis 41 and the second axis 42 is fixed on the box body 10, and the second hinge member having the guide portion 50 and the guide portion 60 is located on the door body 30, in the plane where the top wall of the box body 10 is located, the movement of the first hinge member (axial line segment PQ) relative to the door body 30 (guide portion 50 and guide portion 60) is equivalent to the movement of the axial line segment PQ relative to the door body 30, and is also equivalent to the movement of the box body 10 relative to the door body 30.

[0167] In the following description, for the convenience of explanation, the movement of the axis line segment PQ relative to the second hinge member (the guide portion 50 and the guide portion 60) provided on the door body 30 in the plane where the top wall of the box body 10 is located is selected to represent the movement of the box body 10 relative to the door body 30. That is, the description of the relative movement of the present invention is described as the relative movement in a two-dimensional plane.

[0168] Indicates the opening angle of the door body 30. When the door body 30 is in a closed state, the opening angle of the door body 30 is recorded as the closing angle G G .

[0169] In some embodiments of the present application, The door front wall 31 is parallel to the plane where the access opening is located.

[0170] In some embodiments of the present application, The door rear wall 33 is perpendicular to the plane where the access opening is located.

[0171] In some embodiments of the present application, The door side wall 32 is parallel to the plane where the access opening is located.

[0172] The door body 30 is relative to the box body 10. Opening angle when opening to open the access opening is a positive number; the door body 30 is closed in the direction When the movement continues to further squeeze the door seal, the opening angle of the door body 30 becomes a negative number.

[0173] In some embodiments of the present application, G G =0°. That is, when the door body 30 is in the closed state, the opening angle It should be noted that the angle G at which the door body 30 is in the closed state is G Not affected by G G =0° limit.

[0174] like Figure 2-Figure 4 and Fig.11 As shown, under the constraints of the guide portion 50 and the first shaft 41, the guide portion 60 and the second shaft 42, the opening process of the door body 30 has a first stage. The first stage is as follows:

[0175] In some embodiments of the present application, the guide trajectory line S has a first guide point P1, a second guide point P2, and a third guide point P3 which are sequentially close to the door side wall 32.

[0176] The first guiding point P1, the second guiding point P2, and the third guiding point P3 are sequentially close to the door front wall 31. That is, the distances between the first guiding point P1, the second guiding point P2, and the third guiding point P3 and the door front wall 31 are sequentially reduced.

[0177] The guide track line S extends from the first guide point P1 to a side close to the door side wall 32 to a third guide point P3.

[0178] The guide track line S extends from the first guide point P1 to a side close to the door front wall 31 to a third guide point P3.

[0179] The guide trajectory line S extends from the first guide point P1 through the second guide point P2 to the third guide point P3.

[0180] In some embodiments of the present application, the guide track line K has a first guide point Q1, a second guide point Q2, and a third guide point Q3 which are sequentially close to the door side wall 32.

[0181] The first guide point Q1, the second guide point Q2, and the third guide point Q3 are sequentially away from the door front wall 31. That is, the distances between the first guide point Q1, the second guide point Q2, and the third guide point Q3 and the door front wall 31 are sequentially increased.

[0182] The guide track line K extends from the first guide point Q1 to the side close to the door side wall 32 to the third guide point Q3.

[0183] The guide track line K extends from the first guide point Q1 to a side away from the door front wall 31 to a third guide point Q3 .

[0184] The guide trajectory line K extends from the first guide point Q1 through the second guide point Q2 to the third guide point Q3.

[0185] When the door body 30 is opened from the first angle G1 to the third angle G3 , the first central axis P moves toward a side close to the door front wall 31 and the door side wall 32 .

[0186] When the door body 30 is opened from the first angle G1 to the third angle G3, the second central axis Q moves away from the door front wall 31 and closer to the door side wall 32. The first angle G1 is less than the third angle G3.

[0187] When the door body 30 is opened from the first angle G1 to the third angle G3 , the first central axis P moves from the first guiding point P1 to the third guiding point P3 via the second guiding point P2 .

[0188] When the door body 30 is opened from the first angle G1 to the third angle G3, the second central axis Q moves from the first guide point Q1 to the third guide point Q3 via the second guide point Q2.

[0189] In some embodiments of the present application, when the door body 30 opens from the first angle G1 to the second angle G2, the center point I of the axis moves from the first center point I1 to the side close to the door front wall 31 and the door side wall 32 to the second center point I2.

[0190] When the door body 30 is opened from the second angle G2 to the third angle G3, the center point I of the axis moves from the second center point I2 to the side away from the door front wall 31 and close to the door side wall 32 to the third center point I3.

[0191] When the door body 30 is opened from the first angle G1 to the third angle G3, the center point I of the axis moves from the first center point I1 to the third center point I3 via the second center point I2.

[0192] When the door body 30 opens from the first angle G1 to the third angle G3 , the center point I of the axis first moves toward the side close to the door front wall 31 and the door side wall 32 , and then moves away from the door front wall 31 and toward the side close to the door side wall 32 .

[0193] In some embodiments of the present application, the first angle G1 is less than the second angle G2 and is less than the third angle G3.

[0194] During the first stage of opening, the door body 30 opens at an angle of When , the first central axis P is located at the first guiding point P1 of the guiding trajectory line S, the second central axis Q is located at the first guiding point Q1 of the guiding trajectory line K, and the center point of the axis is located at the first midpoint I1.

[0195] Door body 30 opening angle When , the first central axis P is located at the second guide point P2 of the guide trajectory line S, the second central axis Q is located at the second guide point Q2 of the guide trajectory line K, and the center point of the axis is located at the second midpoint I2.

[0196] Door body 30 opening angle When , the first central axis P is located at the third guide point P3 of the guide trajectory line S, the second central axis Q is located at the third guide point Q3 of the guide trajectory line K, and the center point of the axis is located at the second midpoint I3.

[0197] In some embodiments of the present application, G G =G1.

[0198] In some implementations of the present application, the first angle G1 = 0°.

[0199] In some embodiments of the present application, G G = G1 = 0°. At this time, when the opening angle of the door body 30 is the first angle G1 = 0°, the door body 30 is in a closed state.

[0200] The first stage is the process of the door body 30 opening from the first angle G1 to the third angle G3. G =G1 or G G = G1 = 0°) through G2 to G3. In this process, the first central axis P moves toward the side close to the door front wall 31 and the door side wall 32. The second central axis Q moves away from the door front wall 31 and toward the side close to the door side wall 32.

[0201] Specifically, the first central axis P moves from the first guide point P1 along the guide track line S through the second guide point P2 to the third guide point P3. The second central axis Q moves from the first guide point Q1 along the guide track line K through the second guide point Q2 to the third guide point Q3.

[0202] In the above first stage of opening process, the second hinge member (guide portion 50 / guide portion 60 / door body 30) is used as a reference for description.

[0203] The door body 30 is at a first angle G1 (configurable, G G =G1 or G G=G1=0°) to the third angle G3, the axis line segment PQ rotates clockwise from P1Q1 and moves to P2Q2 and P3Q3 in sequence. That is, the movement trend of the axis line segment PQ is P1Q1→P2Q2→P3Q3. At the same time, the movement trend of the axis center point I as the axis line segment PQ moves is I1→I2→I3. That is, during the opening process of the door body 30, relative to the door body 30, the axis center point I first moves to the side close to the door front wall 31 and the door side wall 32, and then moves to the side away from the door front wall 31 and close to the door side wall 32.

[0204] Since the guide part 50 and the guide part 60 are arranged on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 arranged on the box body 10. It is concluded that: taking the door body 30 as a reference, the door body 30 is moved from the first angle G1 (which can be set, G G =G1 or G G During the whole process of opening the door from the front door 31 to the third angle G3 (=G1=0°), the box body 10 (i.e., the hinge plate 40) keeps rotating clockwise relative to the door body 30 to open, and first moves a certain distance to the side close to the door front wall 31 and the door side wall 32, and then moves a certain distance to the side away from the door front wall 31 and close to the door side wall 32.

[0205] In summary, the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the second angle G2, with the door body 30 (guide groove / guiding groove) as a reference, the box body 10 has a translational motion while rotating relative to the door body 30. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the door side wall 32 and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0206] When the door body 30 is opened from the second angle G2 to the third angle G3, with the door body 30 (guide groove / guiding groove) as a reference, the box body 10 performs a translational motion while performing a rotational motion relative to the door body 30. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the door side wall 32, and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0207] According to the relativity of the movement, taking the box 10 as a reference, the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G= G1 = 0°) to the second angle G2, the door body 30 has a translational movement while rotating. The translational movement is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0208] When the door body 30 is opened from the second angle G2 to the third angle G3, the door body 30 has a translational motion while rotating. The translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0209] like Figure 4-Figure 6 and Fig.12 As shown, under the constraints of the guide portion 50 and the first shaft 41, the guide portion 60 and the second shaft 42, the opening process of the door body 30 has a second stage. The second stage is as follows:

[0210] In some embodiments of the present application, the guide trajectory line S has a fourth guide point P4 and a fifth guide point P5.

[0211] The third guiding point P3 , the fourth guiding point P4 , and the fifth guiding point P5 are respectively away from the door side wall 32 .

[0212] The third guide point P3, the fourth guide point P4, and the fifth guide point P5 are sequentially away from the door front wall 31. That is, the distances between the third guide point P3, the fourth guide point P4, and the fifth guide point P5 and the door front wall 31 increase sequentially.

[0213] The guide track line S extends from the third guide point P3 to a side away from the door side wall 32 to a fifth guide point P5.

[0219] Then, the third guiding point P3, the fourth guiding point P4, the fifth guiding point P5, and the first guiding point P1 are sequentially away from the door front wall 31. That is, the distances between the third guiding point P3, the fourth guiding point P4, the fifth guiding point P5, and the first guiding point P1 and the door front wall 31 increase sequentially.

[0220] The guide track line S extends from the third guide point P3 to the side away from the door side wall 32 to the first guide point P1.

[0221] The guide track line S extends from the third guide point P3 to the side away from the door front wall 31 to the first guide point P1.

[0222] The guide trajectory line S extends from the third guide point P3 to the first guide point P1 through the fourth guide point P4 and the fifth guide point P5 in sequence.

[0223] In some embodiments of the present application, the guide trajectory line K has a fourth guide point Q4 and a fifth guide point Q5.

[0224] Among them, the third guide point Q3, the fourth guide point Q4, and the fifth guide point Q5 are close to the door side wall 32 in sequence.

[0225] The third guide point Q3, the fourth guide point Q4, and the fifth guide point Q5 are sequentially away from the door front wall 31. That is, the distances between the third guide point Q3, the fourth guide point Q4, and the fifth guide point Q5 and the door front wall 31 are sequentially increased.

[0226] The guide track line K extends from the third guide point Q3 to the side close to the door side wall 32 to the fifth guide point Q5.

[0227] The guide track line K extends from the third guide point Q3 to a side away from the door front wall 31 to a fifth guide point Q5.

[0228] The guide trajectory line K extends from the third guide point Q3 through the fourth guide point Q4 to the fifth guide point Q5.

[0229] When the door body 30 is opened from the third angle G3 to the fifth angle G5 , the first central axis P moves toward a side away from the door front wall 31 and the door side wall 32 .

[0230] When the door body 30 is opened from the third angle G3 to the fifth angle G5, the second central axis Q moves away from the door front wall 31 and closer to the door side wall 32. The third angle G3 is less than the fifth angle G5.

[0231] When the door body 30 is opened from the third angle G3 to the fifth angle G5, the first central axis P moves from the third guiding point P3 to the fifth guiding point P5 via the fourth guiding point P4.

[0232] When the door body 30 is opened from the third angle G3 to the fifth angle G5, the second central axis Q moves from the third guide point Q3 to the fifth guide point Q5 via the fourth guide point Q4.

[0233] In some embodiments of the present application, when the door body 30 is opened from the third angle G3 to the fifth angle G5, the axis center point I moves from the third center point I3 to the side away from the door front wall 31 and close to the door side wall 32 through the fourth center point I4 to the fifth center point I5. The third angle G3 is less than the fifth angle G5.

[0234] During the second stage of opening, the door 30 opens at an angle of When , the first central axis P is located at the third guide point P3 of the guide trajectory line S, the second central axis Q is located at the third guide point Q3 of the guide trajectory line K, and the center point of the axis is located at the third midpoint I3.

[0235] Door body 30 opening angle When , the first central axis P is located at the fourth guide point P4 of the guide trajectory line S, the second central axis Q is located at the fourth guide point Q4 of the guide trajectory line K, and the center point of the axis is located at the fourth midpoint I4.

[0236] Door body 30 opening angle When , the first central axis P is located at the fifth guide point P5 of the guide trajectory line S, the second central axis Q is located at the fifth guide point Q5 of the guide trajectory line K, and the center point of the axis is located at the fifth midpoint I5.

[0237] In some embodiments of the present application, G4=90°.

[0238] In some embodiments of the present application, when the door body 30 is opened to G4=90°, the door front wall 31 is flush with the first body side wall, where “flush” includes the case where the distance between the two planes of the door front wall 31 and the first body side wall is not greater than 3 mm.

[0239] The second stage is the process of the door body 30 opening from the third angle G3 to the fifth angle G5. The door body 30 opens from the third angle G3 to the fifth angle G5 via the fourth angle G4. In this process, the first central axis P moves away from the door front wall 31 and the door side wall 32. The second central axis Q moves away from the door front wall 31 and close to the door side wall 32.

[0240] Specifically, when the door body 30 is opened from the third angle G3 to the fifth angle G5, the first central axis P moves from the third guide point P3 along the guide trajectory S through the fourth guide point P4 to the fifth guide point P5. The second central axis Q moves from the third guide point Q3 along the guide trajectory K through the fourth guide point Q4 to the fifth guide point Q5.

[0241] In the above second stage of opening process, the second hinge member (guide portion 50 / guide portion 60 / door body 30) is used as a reference for description.

[0242] In the process of the door body 30 opening from the third angle G3 to the fifth angle G5, the axis line segment PQ rotates clockwise from P3Q3 and moves to P4Q4 and P5Q5 in sequence. That is, the movement trend of the axis line segment PQ is P3Q3→P4Q4→P5Q5. At the same time, the movement trend of the axis center point I as the axis line segment PQ moves is I3→I4→I5. That is, in the process of the door body 30 opening, relative to the door body 30, the axis center point I moves away from the door front wall 31 and closer to the door side wall 32.

[0243] Since the guide portion 50 and the guide portion 60 are disposed on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 disposed on the box body 10. It is concluded that: taking the door body 30 as a reference, during the entire process of the door body 30 opening from the third angle G3 to the fifth angle G5, the box body 10 (i.e., the hinge plate 40) keeps rotating clockwise relative to the door body 30 to open, and moves a certain distance to the side away from the door front wall 31 and close to the door side wall 32.

[0244] In summary, when the door body 30 is opened from the third angle G3 to the fifth angle G5, with the door body 30 (guide groove / guiding groove) as a reference, the box body 10 has a translational motion while rotating relative to the door body 30. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the door side wall 32 and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0245] According to the relativity of motion, taking the box body 10 as a reference, when the door body 30 is opened from the third angle G3 to the fifth angle G5, the door body 30 has a translational motion while rotating. The translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32, and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0246] like Figure 6-Figure 8 and Fig.13 As shown, under the constraints of the guide portion 50 and the first shaft 41, the guide portion 60 and the second shaft 42, the opening process of the door body 30 has a third stage. The third stage is as follows:

[0247] In some embodiments of the present application, the guide trajectory line S has a sixth guide point P6 and a seventh guide point P7 which are successively close to the door side wall 32 .

[0248] The fifth guiding point P5, the sixth guiding point P6, and the seventh guiding point P7 are sequentially close to the door side wall 32. The fifth guiding point P5, the sixth guiding point P6, and the seventh guiding point P7 are sequentially close to the door front wall 31.

[0249] According to the relative position relationship between the first guiding point P1 and the fifth guiding point P5 , the first guiding point P1 , the fifth guiding point P5 , the sixth guiding point P6 , and the seventh guiding point P7 are sequentially close to the door side wall 32 .

[0250] The first guide point P1, the fifth guide point P5, the sixth guide point P6, and the seventh guide point P7 are successively closer to the door front wall 31. That is, the distances between the first guide point P1, the fifth guide point P5, the sixth guide point P6, and the seventh guide point P7 and the door front wall 31 are successively reduced.

[0251] The guide track line S extends from the fifth guide point P5 to a side close to the door side wall 32 to a seventh guide point P7.

[0252] The guide track line S extends from the fifth guide point P5 to a side close to the door front wall 31 to a seventh guide point P7.

[0253] The guide trajectory line S extends from the fifth guide point P5 through the sixth guide point P6 to the seventh guide point P7.

[0254] In some embodiments of the present application, the guide track line K has a sixth guide point Q6 and a seventh guide point Q7 which are successively close to the door side wall 32 .

[0255] Among them, the fifth guiding point Q5, the sixth guiding point Q6, and the seventh guiding point Q7 are respectively close to the door side wall 32.

[0256] The fifth guide point Q5, the sixth guide point Q6, and the seventh guide point Q7 are sequentially away from the door front wall 31. That is, the distances between the fifth guide point Q5, the sixth guide point Q6, and the seventh guide point Q7 and the door front wall 31 are sequentially increased.

[0257] The guide track line K extends from the fifth guide point Q5 to the side close to the door side wall 32 to the seventh guide point Q7.

[0258] The guide track line K extends from the fifth guide point Q5 to a side away from the door front wall 31 to a seventh guide point Q7.

[0259] The guide trajectory line K extends from the fifth guide point Q5 through the sixth guide point Q6 to the seventh guide point Q7.

[0260] According to the relative position relationship of the aforementioned guide points, the first guide point Q1, the second guide point Q2, the third guide point Q3, the fourth guide point Q4, the fifth guide point Q5, the sixth guide point Q6, and the seventh guide point Q7 are respectively close to the door side wall 32.

[0261] The first guide point Q1 , the second guide point Q2 , the third guide point Q3 , the fourth guide point Q4 , the fifth guide point Q5 , the sixth guide point Q6 , and the seventh guide point Q7 are respectively away from the door front wall 31 .

[0262] When the door body 30 is opened from the fifth angle G5 to the seventh angle G7 , the first central axis P moves toward a side close to the door front wall 31 and the door side wall 32 .

[0263] When the door body 30 is opened from the fifth angle G5 to the seventh angle G7, the second central axis Q moves away from the door front wall 31 and closer to the door side wall 32. The fifth angle G5 is smaller than the seventh angle G7.

[0264] When the door body 30 is opened from the fifth angle G5 to the seventh angle G7, the first central axis P moves from the fifth guiding point P5 to the seventh guiding point P7 via the sixth guiding point P6.

[0265] When the door body 30 is opened from the fifth angle G5 to the seventh angle G7, the second central axis Q moves from the fifth guide point Q5 to the seventh guide point Q7 via the sixth guide point Q6.

[0266] In some embodiments of the present application, when the door body 30 is opened from the fifth angle G5 to the sixth angle G6, the axis center point I moves from the fifth center point I5 to the side away from the door front wall 31 and close to the door side wall 32 to the sixth center point I6. The fifth angle G5 is less than the sixth angle G6.

[0267] When the door body 30 is opened from the sixth angle G6 to the seventh angle G7, the center point I of the axis moves from the sixth center point I6 to the side close to the door front wall 31 and the door side wall 32 to the seventh center point I7. The sixth angle G6 is less than the seventh angle G7.

[0268] When the door body 30 is opened from the fifth angle G5 to the seventh angle G7, the center point I of the axis moves from the fifth center point I5 to the seventh center point I7 via the sixth center point I6.

[0269] When the door body 30 is opened from the fifth angle G5 to the seventh angle G7, the center point I of the axis first moves away from the door front wall 31 and close to the door side wall 32, and then moves to the side close to the door front wall 31 and the door side wall 32.

[0270] Among them, the fifth angle G5<sixth angle G6<seventh angle G7.

[0271] In the third stage of opening, the door body 30 opens at an angle of When , the first central axis P is located at the fifth guide point P5 of the guide trajectory line S, the second central axis Q is located at the fifth guide point Q5 of the guide trajectory line K, and the center point of the axis is located at the fifth midpoint I5.

[0272] Door body 30 opening angle When , the first central axis P is located at the sixth guide point P6 of the guide trajectory line S, the second central axis Q is located at the sixth guide point Q6 of the guide trajectory line K, and the midpoint of the axis is located at the sixth midpoint I6.

[0273] Door body 30 opening angle When , the first central axis P is located at the seventh guide point P7 of the guide trajectory line S, the second central axis Q is located at the seventh guide point Q7 of the guide trajectory line K, and the center point of the axis is located at the seventh midpoint I7.

[0274] The third stage is the process of the door body 30 opening from the fifth angle G5 to the seventh angle G7. The door body 30 opens from the fifth angle G5 to G7 via G6. In this process, the first central axis P moves toward the side close to the door front wall 31 and the door side wall 32. The second central axis Q moves away from the door front wall 31 and toward the side close to the door side wall 32.

[0275] Specifically, when the door body 30 is opened from the fifth angle G5 to the seventh angle G7, the first central axis P moves from the fifth guide point P5 along the guide trajectory S through the sixth guide point P6 to the seventh guide point P7. The second central axis Q moves from the fifth guide point Q5 along the guide trajectory K through the sixth guide point Q6 to the seventh guide point Q7.

[0276] In the above third stage of opening process, the second hinge member (guide portion 50 / guide portion 60 / door body 30) is used as a reference for description.

[0277] In the process of the door body 30 opening from the fifth angle G5 to the seventh angle G7, the axis line segment PQ rotates clockwise from P5Q5 and moves to P6Q6 and P7Q7 in sequence. That is, the movement trend of the axis line segment PQ is P5Q5→P6Q6→P7Q7. At the same time, the movement trend of the axis center point I as the axis line segment PQ moves is I5→I6→I7. That is, in the process of the door body 30 opening, relative to the door body 30, the axis center point I first moves to the side away from the door front wall 31 and close to the door side wall 32, and then moves to the side close to the door front wall 31 and the door side wall 32.

[0278] Since the guide part 50 and the guide part 60 are arranged on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 arranged on the box body 10. It is concluded that: taking the door body 30 as a reference, during the whole process of the door body 30 opening from the fifth angle G5 to the seventh angle G7, the box body 10 (i.e., the hinge plate 40) keeps rotating clockwise relative to the door body 30 to open, and first moves a certain distance to the side away from the door front wall 31 and close to the door side wall 32, and then moves a certain distance to the side close to the door front wall 31 and the door side wall 32.

[0279] In summary, when the door body 30 is opened from the fifth angle G5 to the sixth angle G6, with the door body 30 (guide groove / guiding groove) as a reference, the box body 10 has a translational motion while rotating relative to the door body 30. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the door side wall 32 and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0280] When the door body 30 is opened from the sixth angle G6 to the seventh angle G7, with the door body 30 (guide groove / guiding groove) as a reference, the box body 10 performs a translational motion while performing a rotational motion relative to the door body 30. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the door side wall 32, and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0281] According to the relativity of motion, taking the box body 10 as a reference, when the door body 30 is opened from the fifth angle G5 to the sixth angle G6, the door body 30 has a translational motion while performing a rotational motion. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0282] When the door body 30 is opened from the sixth angle G6 to the seventh angle G7, the door body 30 has a translational motion while rotating. The translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0283] like Figure 8-Figure 9 and Fig.14 As shown, under the constraints of the guide portion 50 and the first shaft 41, the guide portion 60 and the second shaft 42, the opening process of the door body 30 has a fourth stage. The fourth stage is as follows:

[0284] In some embodiments of the present application, the guide trajectory line S has an eighth guide point P8.

[0285] The seventh guiding point P7 and the eighth guiding point P8 are respectively close to the door side wall 32. The seventh guiding point P7 and the eighth guiding point P8 are respectively close to the door front wall 31.

[0286] The guide track line S extends from the seventh guide point P7 to the side close to the door side wall 32 to the eighth guide point P8.

[0287] The guide track line S extends from the seventh guide point P7 to the side close to the door front wall 31 to the eighth guide point P8.

[0288] According to the relative position relationship among the first guide point P1 , the fifth guide point P5 , the sixth guide point P6 , and the seventh guide point P7 , the first guide point P1 , the fifth guide point P5 , the sixth guide point P6 , the seventh guide point P7 , and the eighth guide point P8 are sequentially close to the door side wall 32 .

[0289] The first guide point P1, the fifth guide point P5, the sixth guide point P6, the seventh guide point P7, and the eighth guide point P8 are successively close to the door front wall 31. That is, the distances between the first guide point P1, the fifth guide point P5, the sixth guide point P6, the seventh guide point P7, and the eighth guide point P8 and the door front wall 31 are successively reduced.

[0290] The guide track line S extends from the first guide point P1 to the side close to the door side wall 32 to an eighth guide point P8.

[0291] The guide track line S extends from the first guide point P1 to a side close to the door front wall 31 to an eighth guide point P8.

[0292] The guide trajectory line S extends from the first guide point P1 to the eighth guide point P8 through the fifth guide point P5 , the sixth guide point P6 , the seventh guide point P7 in sequence.

[0293] In some embodiments of the present application, the eighth guiding point P8 is located on a side of the third guiding point P3 close to the door side wall 32 .

[0294] The eighth guiding point P8 is located on a side of the third guiding point P3 close to the door front wall 31 .

[0295] The seventh guide point P7 is located on a side of the third guide point P3 away from the door side wall 32 .

[0296] The seventh guiding point P7 is located on a side of the third guiding point P3 away from the door front wall 31 .

[0297] Then, the guide trajectory line S extends from the first guide point P1 through the fifth guide point P5, the sixth guide point P6, the seventh guide point P7, the third guide point P3 to the eighth guide point P8.

[0298] In some embodiments of the present application, the guide track line K has an eighth guide point Q8 close to the door side wall 32 .

[0299] Among them, the seventh guide point Q7 and the eighth guide point Q8 are respectively close to the door side wall 32 .

[0300] The seventh guide point Q7 and the eighth guide point Q8 are successively closer to the door front wall 31. That is, the distances between the seventh guide point Q7 and the eighth guide point Q8 and the door front wall 31 are successively reduced.

[0301] The guide track line K extends from the seventh guide point Q7 to the side close to the door side wall 32 to the eighth guide point Q8.

[0302] The guide track line K extends from the seventh guide point Q7 to the side close to the door front wall 31 to the eighth guide point Q8.

[0303] When the door body 30 is opened from the seventh angle G7 to the eighth angle G8, the first central axis P moves toward the side close to the door front wall 31 and the door side wall 32.

[0304] When the door body 30 is opened from the seventh angle G7 to the eighth angle G8, the second central axis Q moves toward the side close to the door front wall 31 and the door side wall 32. The seventh angle G7 is smaller than the eighth angle G8.

[0305] When the door body 30 is opened from the seventh angle G7 to the eighth angle G8, the first central axis P moves from the seventh guide point Q7 to the eighth guide point P8.

[0306] When the door body 30 is opened from the seventh angle G7 to the eighth angle G8, the second central axis Q moves from the seventh guide point Q7 to the eighth guide point Q8.

[0307] In some embodiments of the present application, when the door body 30 opens from the seventh angle G7 to the eighth angle G8, the center point I of the axis moves from the seventh center point I7 to the side close to the door front wall 31 and the door side wall 32 to the eighth center point I8.

[0308] When the door body 30 is opened from the seventh angle G7 to the eighth angle G8, the center point I of the axis moves toward the side close to the door front wall 31 and the door side wall 32.

[0309] In the fourth stage of opening, the door body 30 opens at an angle of When , the first central axis P is located at the seventh guide point P7 of the guide trajectory line S, the second central axis Q is located at the seventh guide point Q7 of the guide trajectory line K, and the center point of the axis is located at the seventh midpoint I7.

[0310] Door body 30 opening angle When , the first central axis P is located at the eighth guide point P8 of the guide trajectory line S, the second central axis Q is located at the eighth guide point Q8 of the guide trajectory line K, and the center point of the axis is located at the eighth midpoint I8.

[0311] The fourth stage is the process of the door body 30 opening from the seventh angle G7 to the eighth angle G8. In the process of the door body 30 opening from the seventh angle G7 to G8, the first central axis P moves toward the side close to the door front wall 31 and the door side wall 32, and the second central axis Q moves toward the side close to the door front wall 31 and the door side wall 32.

[0312] Specifically, when the door body 30 opens from the seventh angle G7 to the eighth angle G8, the first central axis P moves from the seventh guide point P7 to the eighth guide point P8 along the guide track line S. The second central axis Q moves from the seventh guide point Q7 to the eighth guide point Q8 along the guide track line K.

[0313] The opening process in the fourth stage is described with reference to the second hinge member (the guide portion 50 / the guide portion 60 / the door body 30 ).

[0314] In the process of the door body 30 opening from the seventh angle G7 to the eighth angle G8, the axis line segment PQ rotates clockwise from P7Q7 and moves to P8Q8. That is, the movement trend of the axis line segment PQ is P7Q7→P8Q8. At the same time, the movement trend of the axis center point I as the axis line segment PQ moves is I7→I8. That is, in the process of the door body 30 opening, relative to the door body 30, the axis center point I moves to the side close to the door front wall 31 and the door side wall 32.

[0315] Since the guide portion 50 and the guide portion 60 are disposed on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 disposed on the box body 10. It is concluded that: taking the door body 30 as a reference, during the entire process of the door body 30 opening from the seventh angle G7 to the eighth angle G8, the box body 10 (i.e., the hinge plate 40) keeps rotating clockwise relative to the door body 30 to open, and moves a certain distance toward the side close to the door front wall 31 and the door side wall 32.

[0316] In summary, when the door body 30 is opened from the seventh angle G7 to the eighth angle G8, with the door body 30 (guide groove / guiding groove) as a reference, the box body 10 has a translational motion while rotating relative to the door body 30. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the door side wall 32 and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0317] According to the relativity of motion, taking the box body 10 as a reference, when the door body 30 is opened from the seventh angle G7 to the eighth angle G8, the door body 30 has a translational motion while performing a rotational motion. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing to the side away from the door front wall 31.

[0318] like Figure 9-10 and Fig.15 As shown, under the constraints of the guide portion 50 and the first shaft 41, the guide portion 60 and the second shaft 42, the opening process of the door body 30 has a fifth stage. The fifth stage is as follows:

[0319] In some embodiments of the present application, the guiding trajectory line S has a ninth guiding point P9.

[0320] The eighth guiding point P8 and the ninth guiding point P9 are respectively far away from the door side wall 32. The eighth guiding point P8 and the ninth guiding point P9 are respectively far away from the door front wall 31.

[0321] The guide trajectory line S extends from the eighth guide point P8 to a side away from the door side wall 32 to a ninth guide point P9.

[0322] The guide track line S extends from the eighth guide point P8 to the ninth guide point P9 toward the side away from the door front wall 31. That is, the distances between the eighth guide point P8 and the ninth guide point P9 and the door front wall 31 increase successively.

[0323] In some embodiments of the present application, the ninth guiding point P9 is located on a side of the third guiding point P3 close to the door side wall 32 .

[0324] The ninth guiding point P9 is located on a side of the third guiding point P3 close to the door front wall 31 .

[0325] Then, the guide trajectory line S extends from the first guide point P1 through the third guide point P3 and the ninth guide point P9 to the eighth guide point P8.

[0326] In some embodiments of the present application, the guide track line K has a ninth guide point Q9 close to the door side wall 32 .

[0327] Among them, the eighth guiding point Q8 and the ninth guiding point Q9 are respectively close to the door side wall 32 .

[0328] The eighth guide point Q8 and the ninth guide point Q9 are successively closer to the door front wall 31. That is, the distances between the eighth guide point Q8 and the ninth guide point Q9 and the door front wall 31 are successively reduced.

[0329] The guide track line K extends from the eighth guide point Q8 to the side close to the door side wall 32 to the ninth guide point Q9.

[0330] The guide track line K extends from the eighth guide point Q8 to the side close to the door front wall 31 to the ninth guide point Q9.

[0331] When the door body 30 is opened from the eighth angle G8 to the ninth angle G9 , the first central axis P moves toward a side away from the door front wall 31 and the door side wall 32 .

[0332] When the door body 30 is opened from the eighth angle G8 to the ninth angle G9, the second central axis Q moves toward the side close to the door front wall 31 and the door side wall 32. The eighth angle G8 is smaller than the ninth angle G9.

[0333] When the door body 30 is opened from the eighth angle G8 to the ninth angle G9, the first central axis P moves from the eighth guide point Q8 to the ninth guide point P9.

[0334] When the door body 30 is opened from the eighth angle G8 to the ninth angle G9, the second central axis Q moves from the eighth guide point Q8 to the ninth guide point Q9.

[0335] In some embodiments of the present application, during the process of the door body 30 opening from the eighth angle G8 to the ninth angle G9, the axis center point I moves from the eighth center point I8 to the side away from the door front wall 31 and close to the door side wall 32 to the ninth center point I9.

[0336] During the process of the door body 30 opening from the eighth angle G8 to the ninth angle G9, the center point I of the axis moves away from the door front wall 31 and closer to the door side wall 32 .

[0337] In the fifth stage of opening, the door body 30 opens at an angle of When , the first central axis P is located at the eighth guide point P8 of the guide trajectory line S, the second central axis Q is located at the eighth guide point Q8 of the guide trajectory line K, and the center point of the axis is located at the eighth midpoint I8.

[0338] Door opening angle 30 When , the first central axis P is located at the ninth guide point P9 of the guide trajectory line S, the second central axis Q is located at the ninth guide point Q9 of the guide trajectory line K, and the center point of the axis is located at the ninth midpoint I9.

[0339] The fifth stage is the process of the door body 30 opening from the eighth angle G8 to the ninth angle G9. In this process, the first central axis P moves away from the door front wall 31 and the door side wall 32, and the second central axis Q moves toward the door front wall 31 and the door side wall 32.

[0340] Specifically, when the door body 30 opens from the eighth angle G8 to the ninth angle G9, the first central axis P moves from the eighth guide point P8 to the ninth guide point P9 along the guide track line S. The second central axis Q moves from the eighth guide point Q8 to the ninth guide point Q9 along the guide track line K.

[0341] The opening process in the fifth stage is described with reference to the second hinge member (the guide portion 50 / the guide portion 60 / the door body 30 ).

[0342] In the process of the door body 30 opening from the eighth angle G8 to the ninth angle G9, the axis line segment PQ rotates clockwise from P8Q8 and moves to P9Q9. That is, the movement trend of the axis line segment PQ is P8Q8→P9Q9. At the same time, the movement trend of the axis center point I as the axis line segment PQ moves is I8→I9. That is, in the process of the door body 30 opening, relative to the door body 30, the axis center point I moves away from the door front wall 31 and closer to the door side wall 32.

[0343] Since the guide portion 50 and the guide portion 60 are disposed on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 disposed on the box body 10. It is concluded that: taking the door body 30 as a reference, during the entire process of the door body 30 opening from the eighth angle G8 to the ninth angle G9, the box body 10 (i.e., the hinge plate 40) keeps rotating clockwise relative to the door body 30 to open, and moves a certain distance to the side away from the door front wall 31 and close to the door side wall 32.

[0344] In summary, when the door body 30 is opened from the eighth angle G8 to the ninth angle G9, with the door body 30 (guide groove / guiding groove) as a reference, the box body 10 has a translational motion while rotating relative to the door body 30. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the door side wall 32 and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0345] According to the relativity of motion, taking the box body 10 as a reference, when the door body 30 is opened from the eighth angle G8 to the ninth angle G9, the door body 30 has a translational motion while performing a rotational motion. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0346] In some embodiments of the present application, the first guide point P1, the second guide point P2, the third guide point P3, the fourth guide point P4, the fifth guide point P5, the sixth guide point P6, the seventh guide point P7, the eighth guide point P8, and the ninth guide point P9 are located on the guide trajectory line S.

[0347] Along the direction from the door rear wall 33 to the door front wall 31 , the distance between the guide track line S and the door side wall 32 gradually decreases.

[0348] In some embodiments of the present application, the guide track line S is a straight line. The angle between the guide track line S and the front wall of the door is denoted as γ.

[0349] Wherein, γ is not less than the first angle reference value; the first angle reference value is between 27° and 37°. The first angle reference value may be 27°, 32° or 37°. That is, γ≥27° or γ≥32° or γ≥37°.

[0350] When γ≥27°, the fixing space requirement of the mounting block and the small thickness of the door body 30 occupied by the mounting block are met. When γ≥32°, the fixing space requirement of the mounting block and the small thickness of the door body 30 occupied by the mounting block are better met. When γ≥32°, the fixing space requirement of the mounting block and the small thickness of the door body 30 occupied by the mounting block are better met.

[0351] γ is not greater than the second angle reference value; the second angle reference value is between 38° and 48°. The second angle reference value may be 38°, 43° or 48°. That is, γ≤38° or γ≤43° or γ≤48°.

[0352] When γ≤38°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is better met. When γ≤43°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is better met. When γ≤48°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is met.

[0353] γ is too large, resulting in the wall thickness between the guide part 50 and the guide part 60 being too thin, reducing the strength of the guide part 50 and the guide part 60. In addition, when the distance between the end of the guide part 50 away from the door side wall 31 and the door front wall 31 is relatively large, the size of the guide part 60 in the direction perpendicular to the door front wall 31 increases synchronously, and the size of the overall trajectory of the guide part 50 and the guide part 60 in the direction perpendicular to the door front wall 31 becomes larger, resulting in an increase in the thickness of the door body 30, affecting its use on ultra-thin refrigerators. Furthermore, the thickness of the door body 30 is too large, resulting in an increase in the obstruction of the door body 30 to the access port; and in order to ensure that the drawer installed in the storage room can be pulled out, it is necessary to reduce the lateral width of the drawer, resulting in the drawer being unable to effectively utilize the lateral space of the storage room.

[0354] If γ is too small, there will be insufficient space for screws (not limited to screw fixing, any conventional fixing method that can fix two parts) between the two tracks of the guide part 50 and the guide part 60 on the mounting block. In order to meet the fixing requirements, it is necessary to increase the area of ​​the mounting block; and in order to ensure the fixing strength of the mounting block, it is particularly necessary to increase the size of the mounting block in the direction perpendicular to the front wall 31 of the door to increase the position for screws (not limited to screw fixing, any conventional fixing method that can fix two parts). The increase in the size of the mounting block in the direction perpendicular to the front wall 31 of the door will increase the thickness of the door body 30 that matches it, affecting its use on ultra-thin refrigerators. Furthermore, the thickness of the door body 30 is too large, resulting in an increase in the obstruction of the door body 30 to the access port; and in order to ensure that the drawer installed in the storage room can be pulled out, it is necessary to reduce the lateral width of the drawer, resulting in the drawer being unable to effectively utilize the lateral space of the storage room.

[0355] In some embodiments of the present application, when the door body 30 is opened from the first angle G1 to the ninth angle G9, when the door body 30 is opened to the first angle G1, the first central axis P is located at the first guide point P1 of the guide trajectory line S. On the guide trajectory line S, the distance between the first guide point P1 and the door side wall 32 is the largest. On the guide trajectory line S, the distance between the first guide point P1 and the door front wall 31 is the largest.

[0356] In some embodiments of the present application, when the door body 30 is opened from the first angle G1 to the ninth angle G9, when the door body 30 is opened to the eighth angle G8, the first central axis P is located at the eighth guide point P8 of the guide trajectory line S. On the guide trajectory line S, the distance between the eighth guide point P8 and the door side wall 32 is the smallest. On the guide trajectory line S, the distance between the eighth guide point P8 and the door front wall 31 is the smallest.

[0357] In some embodiments of the present application, the guide trajectory line S extends from the first guide point P1 to a side close to the door side wall 32 to an eighth guide point P8.

[0358] The guide track line S extends from the first guide point P1 to a side close to the door front wall 31 to an eighth guide point P8.

[0359] The second guide point P2 , the third guide point P3 , the fourth guide point P4 , the fifth guide point P5 , the sixth guide point P6 , the seventh guide point P7 , and the ninth guide point P9 are located on the guide trajectory line S and between the first guide point P1 and the eighth guide point P8 .

[0360] In some embodiments of the present application, the first angle G1<the second angle G2<the fourth angle G4=90°<the fifth angle G5<the sixth angle G6<the seventh angle G7<the eighth angle G8<the ninth angle G9.

[0361] In some embodiments of the present application, the first guide point Q1, the second guide point Q2, the third guide point Q3, the fourth guide point Q4, the fifth guide point Q5, the sixth guide point Q6, the seventh guide point Q7, the eighth guide point Q8, and the ninth guide point Q9 are located on the guide trajectory line K.

[0362] In some embodiments of the present application, the guide track line K extends from the first guide point Q1 to a side close to the door side wall 32 to a ninth guide point Q9.

[0363] The guide trajectory line K extends from the first guide point Q1 to the side away from the door front wall 31 to the seventh guide point Q7, then extends from the seventh guide point Q7 to the side close to the door front wall 31 to the eighth guide point Q8, and then extends from the eighth guide point Q8 to the side away from the door front wall 31 to the ninth guide point Q9.

[0364] The guide trajectory line K extends from the first guide point Q1 through the second guide point Q2, the third guide point Q3, the fourth guide point Q4, the fifth guide point Q5, the sixth guide point Q6, the seventh guide point Q7, the eighth guide point Q8 to the ninth guide point Q9.

[0365] In some embodiments of the present application, the guide trajectory line K first extends from the first guide point Q1 to the side away from the door front wall 31 and close to the door side wall 32 to the seventh guide point Q7, then extends from the seventh guide point Q7 to the side close to the door front wall 31 and the door side wall 32 to the eighth guide point Q8, and then extends from the eighth guide point Q8 to the side away from the door front wall 31 and close to the door side wall 32 to the ninth guide point Q9.

[0366] Along the direction from the end of the door body 30 away from the door side wall 32 to the door side wall 32, the distance between the guide track line K and the door front wall 31 first increases, then decreases, and then increases again.

[0367] In some embodiments of the present application, the ninth guide point Q9 is located on the side of the seventh guide point Q7 close to the door side wall 32 and the door front wall 31 .

[0368] The seventh guide point Q7 is the point where the distance between the guide track line K and the door front wall 31 is the largest.

[0369] In some embodiments of the present application, the first guide point P1 is located on a side of the first guide point Q1 close to the door rear wall 33 and the door side wall 32. The seventh guide point P7 is located on a side of the seventh guide point Q7 close to the door front wall 31 and the door side wall 32. The ninth guide point P9 is located on a side of the ninth guide point Q9 close to the door front wall 31 and away from the door side wall 32.

[0370] Combining the situations in the first stage, the second stage, the third stage, the fourth stage and the fifth stage, it can be known that: in the process of the door body 30 opening from the first angle G1 to the ninth angle G9, the first axis 41 first moves toward the direction close to the door front wall 31 and the door side wall 32 (G1~G3), and then moves in the opposite direction away from the door front wall 31 and the door side wall 32 (G3~G5), and then moves in the opposite direction toward the door front wall 31 and the door side wall 32 (G5~G8), and then moves in the opposite direction away from the door front wall 31 and the door side wall 32 (G8~G9). In summary, in the process of the door body 30 opening from the first angle G1 to the ninth angle G9, the first axis 41 turns three times relative to the movement direction of the door body 30. The hinge assembly with the above trajectory characteristics reduces the size of the guide portion 50 and makes full use of the small-sized guide portion 50 to complete the opening of the door body 30 at a large angle.

[0371] Combining the situations in the first, second, third, fourth and fifth stages, it can be seen that: according to the relativity of motion, with the box body 10 as a reference, the door body 30 has a translational motion while rotating. The translational displacement component of the translational motion includes a displacement component parallel to the door rear wall 33 and a displacement component parallel to the door side wall 32. Among them, the displacement component parallel to the door rear wall 33 is recorded as the first direction displacement The displacement component parallel to the door side wall 32 is the second displacement direction In different opening stages of the door body 30, the first direction displacement and the second direction displacement There will be different directions.

[0372] In summary, the movement process of the first central axis P and the second central axis Q of the door body 30 during the first stage to the fifth stage, and the movement trend of the synchronous axis center point I, can reveal the movement process of the axis center point I.

[0373] Specifically, Fig.16 As shown, the movement process of the axis center point I relative to the door body 30 includes a first axis trajectory segment.

[0374] First axis trajectory segment: when the door body 30 is opened from the first angle G1 to the second angle G2, the axis center point I moves toward the side close to the door front wall 31 and the door side wall 32.

[0375] The axis center point I moves from the first center point I1 to the side close to the door front wall 31 and the door side wall 32 to the second center point I2.

[0376] Taking the box body 10 as a reference, the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the second angle G2, the door body 30 has a translational movement while rotating. The translational movement is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0377] The door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the second angle G2, the first direction displacement Pointing away from the door side wall 32, the second direction displacement It points to the side away from the front wall 31 of the door.

[0378] like Fig.16 As shown, the movement process of the axis center point I relative to the door body 30 includes a second axis trajectory segment.

[0379] Second axis trajectory segment: when the door body 30 is opened from the second angle G2 to the sixth angle G6, the axis center point I moves away from the door front wall 31 and closer to the door side wall 32.

[0380] The axis center point I moves from the second center point I2 to the side away from the door front wall 31 and close to the door side wall 32 through the third center point I3, the fourth center point I4, the fifth center point I5 to the sixth center point I6.

[0381] Taking the box body 10 as a reference, when the door body 30 is opened from the second angle G2 to the sixth angle G6, the door body 30 has a translational motion while rotating. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0382] When the door body 30 is opened from the second angle G2 to the sixth angle G6, the first direction displacement Pointing away from the door side wall 32, the second direction displacement Point to the side of the door front wall 31.

[0383] In some embodiments of the present application, the difference between the sixth angle G6 and 90° is denoted as ΔG6;

[0384] Wherein, ΔG6 is not less than the first reference difference; the first reference difference is between 0° and 3°. The first reference difference may be 0°, 1° or 3°. That is, ΔG6≥0° or ΔG6≥1° or ΔG6≥3°.

[0385] When ΔG6≥0°, the door body 30 meets the requirements for shielding the access opening. When ΔG6≥1°, the door body 30 meets the requirements for shielding the access opening better. When ΔG6≥3°, the door body 30 meets the requirements for shielding the access opening better.

[0386] ΔG6 is not greater than the second reference difference; the second reference difference is between 5° and 7°. The second reference difference may be 5°, 6° or 7°. That is, ΔG6≤5° or ΔG6≤6° or ΔG6≤7°.

[0387] When ΔG6≤5°, the maximum angle requirement of the door body 30 of the refrigerator placed in the storage cabinet 100 can be better met. When ΔG6≤6°, the maximum angle requirement of the door body 30 of the refrigerator placed in the storage cabinet 100 can be better met. When ΔG6≤7°, the maximum angle requirement of the door body 30 of the refrigerator placed in the storage cabinet 100 can be met.

[0388] Among them, ΔG6 is too small, and after the door body 30 is opened to 90°, the displacement of the door body 30 moving outward is too small, and the door body 30 blocks a large amount of the access opening, which is inconvenient for users to take and place items.

[0389] ΔG6 is too large, and after the door body 30 is opened to 90°, the outward displacement is too large. The distance between the door body 30 and the storage cabinet 100 is too close, and the maximum angle that the door body 30 of the refrigerator placed in the storage cabinet 100 can be opened is reduced, which is not conducive to the door body 30 opening to a larger angle, and is especially inconvenient for users to take and place items placed on the inside of the door body 30.

[0390] like Fig.16 As shown, the movement process of the axis center point I relative to the door body 30 includes a third axis trajectory segment.

[0391] The third axis trajectory segment: when the door body 30 is opened from the sixth angle G6 to the eighth angle G8, the axis center point I moves toward the side close to the door front wall 31 and the door side wall 32.

[0392] The axis center point I moves from the sixth center point I6 to the side close to the door front wall 31 and the door side wall 32 through the seventh center point I7 to the eighth center point I8.

[0393] Taking the box body 10 as a reference, when the door body 30 is opened from the sixth angle G6 to the eighth angle G8, the door body 30 has a translational motion while rotating. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0394] When the door body 30 is opened from the sixth angle G6 to the eighth angle G8, the first direction displacement Pointing away from the door side wall 32, the second direction displacement It points to the side away from the front wall 31 of the door.

[0395] like Fig.16 As shown, the movement process of the axis center point I relative to the door body 30 includes a fourth axis trajectory segment.

[0396] Fourth axis trajectory segment: when the door body 30 is opened from the eighth angle G8 to the ninth angle G9, the axis center point I moves away from the door front wall 31 and closer to the door side wall 32.

[0397] The axis center point I moves from the eighth center point I8 to a side away from the door front wall 31 and close to the door side wall 32 to a ninth center point I9.

[0398] Taking the box body 10 as a reference, when the door body 30 is opened from the eighth angle G8 to the ninth angle G9, the door body 30 has a translational motion while rotating. The translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0399] In the process of the door body 30 opening from the eighth angle G8 to the ninth angle G9, the first direction displacement Pointing away from the door side wall 32, the second direction displacement Point to the side of the door front wall 31.

[0400] When the door body 30 is opened from the first angle G1 to the ninth angle G9, the trajectory of the axis center point I moving relative to the door body 30 is recorded as the axis center point trajectory line. Among them, the distance between the sixth midpoint I6 on the axis center point trajectory line and the door front wall 31 is the largest.

[0401] It should be noted that “pointing toward the door side wall 32 ” refers to the direction from the end of the door body 30 opposite to the door side wall 32 toward the door side wall 32 ;

[0402] “Directed away from the door side wall 32 ” means that it is directed from the door side wall 32 to the direction of the end of the door body 30 opposite to the door side wall 32 ;

[0403] “Towards the side of the door front wall 31” refers to the direction from the door rear wall 33 to the door front wall 31;

[0404] “Directed to the side away from the door front wall 31 ” refers to the direction from the door front wall 31 to the door rear wall 33 .

[0405] In addition, it should be noted that the first direction displacement Second direction displacement All of them are instantaneous relative translation displacements, to illustrate the instantaneous translation movement trend of the door body 30 relative to the box body 10.

[0406] See also Figure 17-Figure 24As shown; in the plane where the top wall of the box body 10 is located, on the side of the box body 10 close to the door body 30, a displacement coordinate system AOB is established. Specifically, in the displacement coordinate system AOB, OB is perpendicular to the plane where the access port is located, and OA is parallel to the plane where the access port is located. In the displacement coordinate system AOB, the direction from the second body side wall to the first body side wall is defined as positive, and the direction from the access port to the door front wall 31 when the door body 30 is closed (from back to front) is defined as positive. It should be noted that during the opening of the door body 30, the displacement coordinate system AOB remains stationary relative to the box body 10, and it does not move with the opening of the door body 30. During the opening of the door body 30, the relative position of the door body coordinate system XOY relative to the displacement coordinate system AOB changes continuously with the different opening angles of the door body 30. When the opening angle of the door body 30 is determined, the instantaneous relative position of the door body coordinate system XOY relative to the displacement coordinate system AOB remains relatively stationary.

[0407] In some embodiments of the present application, in the displacement coordinate system AOB, the door body 30 has a first direction displacement parallel to the door rear wall 33. The second direction displacement parallel to the door side wall 32 Displacement in the first direction The displacement on the A axis is The displacement on the B axis is Second direction displacement The displacement on the A axis is The displacement on the B axis is

[0408] (1) Figure 17-Figure 20 As shown, the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to G4 = 90°, during the process of the door body 30 rotating counterclockwise relative to the box body 10 to open, the door side wall 32, the door rear wall 33 and the door front wall 31 also rotate counterclockwise during the opening process at this stage. In the plane where the top wall of the box body 10 is located, along the direction from the second side edge N to the first side edge W (the door rear wall 33 to the door front wall 31), the door side wall 32 extends outward and forward; along the direction from the door side wall 32 to the end of the door body 30 opposite to the door side wall 32, the door rear wall 33 extends inward and forward.

[0409] In the above opening process (the first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to G4 = 90°), the door side wall 32 starts to rotate counterclockwise from a state parallel to the reference plane M0, the angle between the door side wall 32 and the plane where the access port is located gradually decreases, and the angle between the door side wall 32 and the reference plane M0 gradually increases; that is, when the door body 30 is at the first angle G1 (which can be set, G G=G1 or G G = G1 = 0°) to G4 = 90°, relative to the box body 10, along the direction from the second side edge N to the first side edge W, the door side wall 32 extends to the side away from the second body side wall and the access opening. At the same time, as the opening angle of the door body 30 increases, the angle between the door rear wall 33 and the plane where the access opening is located gradually increases, and the angle between the door rear wall 33 and the reference plane M0 gradually decreases; that is, when the door body 30 is opened from the first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to G4 = 90°, relative to the box body 10, along the direction from the door side wall 32 to the end of the door body 30 opposite to the door side wall 32, the door rear wall 33 extends in a direction away from the first body side wall and the access port (close to the second body side wall and away from the access port).

[0410] (1.1) During the opening process of the door body 30, the door body 30 includes a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the second angle G2.

[0411] From the above description, it can be seen that: when the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the second angle G2, with the box body 10 as a reference, the door body 30 has a first direction displacement parallel to the door rear wall 33 and pointing away from the door side wall 32 The second direction parallel to the door side wall 32 and pointing away from the door front wall 31 is displaced
