[0043] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are some, rather than all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0044] Basic structure

[0045] Please refer to Figure 1 , Figure 1 It is a schematic structural diagram of an embodiment of a prior art refrigeration device.

[0046] In the prior art, the hinge structure applied to the opening and closing of the door of a refrigeration device such as a refrigerator usually adopts a single hinge shaft design. For example, the box body 11 of the refrigerator 10 is provided with a hinge fixing plate 12, and a hinge shaft 13 is provided on the hinge fixing plate 12. The door body 14 of the refrigerator 10 is provided with a shaft hole (not shown in the figure), and the hinge shaft 13 is inserted into the shaft hole. The hinge shaft 13 can rotate in the shaft hole, so that the door body 14 can rotate relative to the box body 11, thereby realizing the opening and closing of the door body 14.

[0047] As the home decoration style gradually tends to be integral, concealed, and simple, the built-in installation of the refrigerator 10 has emerged accordingly. For example, the refrigerator 10 is embedded in the cabinet 15. However, limited by the single hinge shaft design of the existing hinge structure, the door body 14 may extend beyond the outer side wall 111 of the box body 11 during the rotation relative to the box body 11, which leads to the potential risk of interference and collision between the door body 14 and the external structure (such as the cabinet 15, etc.) during the rotation process.

[0048] In view of this, the embodiments of the present application provide a box body device that can reduce the degree to which the door body extends beyond the outer side wall of the box body during rotation, which will be elaborated in detail below.

[0049] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of an embodiment of the box body device of the present application.

[0050] In one embodiment, the box body device may be a refrigeration device such as a refrigerator or a freezer. Of course, the box body device may also be other devices having a box body 20 and a door body 30 and requiring the door body 30 to be able to rotate relative to the box body 20. Hereinafter, the box body device is taken as an example of a refrigerator for elaboration, which is only for the need of discussion and does not limit the specific form of the box body device.

[0051] The box body device includes a box body 20. The box body 20 is the storage medium of the box body device, and users store the items to be refrigerated or frozen in the box body 20. Specifically, an accommodation space 21 is provided inside the box body 20, and the accommodation space 21 has an opening 22. The items to be refrigerated or frozen are stored in the accommodation space 21 through the opening 22.

[0052] The box body device further includes a door body 30, and the door body 30 is used to block the opening 22 of the accommodation space 21. When the door body 30 blocks the opening 22, that is, when the door body 30 is in the closed state, a relatively closed space is formed inside the box body 20 for storing items. The door body 30 is rotatably connected to the pivot side 23 of the box body 20, that is, the door body 30 can rotate relative to the box body 20. The box body 20 also has a target side 24, and the pivot side 23 and the target side 24 are oppositely arranged on both sides of the opening 22.

[0053] The box body device further includes a hinge assembly 40. The hinge assembly 40 is provided on the pivoting side 23 of the box body 20, and the hinge assembly 40 pivotally connects the box body 20 and the door body 30, that is, realizes the rotational connection between the box body 20 and the door body 30. Specifically, the hinge assembly 40 includes a first connecting member 41 and a second connecting member 42. The first connecting member 41 is provided on one of the box body 20 and the door body 30, and the second connecting member 42 is provided on the other. The first connecting member 41 is provided with a sliding shaft, and the second connecting member 42 is provided with a sliding rail. The sliding shaft is connected to the sliding rail, and the sliding shaft can move along the sliding rail. During the rotation of the door body 30 relative to the box body 20, the sliding shaft moves along the sliding rail.

[0054] It should be noted that the first connecting member 41 and the second connecting member 42 can be part of the box body 20 and the door body 30, that is, the first connecting member 41 and the second connecting member 42 can be an integral structure with the box body 20 and the door body 30. For example, when the first connecting member 41 is provided on the box body 20 and the second connecting member 42 is provided on the door body 30, the first connecting member 41 can be an integral structure with the box body 20, and the second connecting member 42 can be an integral structure with the door body 30. Especially when the sliding rail is in the form of a groove, the surface of the door body 30 is recessed to directly form the sliding rail, and the sliding shaft is embedded in the sliding rail. At this time, the part of the door body 30 where the sliding rail is located can be understood as the second connecting member 42.

[0055] In an embodiment, the end face of the door body 30 facing the hinge assembly 40 has an inner edge 31, an outer edge 32 and a side edge 33. The inner edge 31 and the outer edge 32 are spaced apart along the first direction Z1 and both extend along the second direction Z2. When the door body 30 closes the opening 22, the inner edge 31 is closer to the box body 20 than the outer edge 32. The side edge 33 is located on the pivoting side 23, and the inner edge 31 and the outer edge 32 are connected by the side edge 33. The side edge 33 extends along the first direction Z1. When the door body 30 closes the opening 22, the side edge 33 is perpendicular to the plane 221 where the opening 22 is located.

[0056] The door body 30 has a first inner edge 34 and an outer edge 35 on the pivoting side 23. The first inner edge 34 and the outer edge 35 are spaced apart along the first direction Z1 and both extend along the third direction Z3. When the door body 30 closes the opening 22, the first inner edge 34 is closer to the box body 20 than the outer edge 35. The first inner edge 34 connects the intersection of the inner edge 31 and the side edge 33, and the outer edge 35 connects the intersection of the outer edge 32 and the side edge 33.

[0057] The door body 30 also has a second inner edge 36 on the side away from the pivoting side 23. The second inner edge 36 extends along the third direction Z3. When the door body 30 closes the opening 22, the plane passing through the first inner edge 34 and the second inner edge 36 is parallel to the plane 221 where the opening 22 is located. Users usually grasp the side of the door body 30 away from the pivoting side 23 to open the door body 30.

[0058] Among them, the first direction Z1, the second direction Z2, and the third direction Z3 are perpendicular to each other in pairs. When the box device is correctly placed, both the first direction Z1 and the second direction Z2 are horizontal directions, and the third direction Z3 is a vertical direction. The pivot side 23 and the target side 24 are arranged opposite to each other along the second direction Z2. Figure 2 The third direction Z3 is perpendicular to the plane of the drawing, so the third direction Z3 appears as a point in Figure 2 Similarly, the first inner edge 34, the outer edge 35, and the second inner edge 36 appear as points in Figure 2 in the form of points.

[0059] In one embodiment, the box device further includes a door seal 50, and the door seal 50 is provided on the door body 30. The door body 30 seals the opening 22 of the accommodation space 21 through the door seal 50, so that when the door body 30 seals the opening 22, the accommodation space 21 can have a good sealing effect. The door seal 50 has a third inner edge 51 on the pivot side 23, and the third inner edge 51 extends along the third direction Z3, and the third inner edge 51 is spaced from the door body 30. Similarly, the third inner edge 51 appears as a point in Figure 2 in the form of a point.

[0060] It should be noted that the box device of the embodiment of the present application can adopt a design of a single-opening door, a double-opening door, or even more door bodies 30. The box device is provided with an independent accommodation space 21 corresponding to each door body 30, that is, the door body 30 and the accommodation space 21 are in one-to-one correspondence, and the door body 30 is used to seal the accommodation space 21 corresponding to it.

[0061] Linear slide rail cooperation

[0062] Please refer to Figure 2 and Figure 3 , Figure 3 is a schematic structural diagram of the first embodiment of the sliding shaft and the slide rail of the present application.

[0063] In one embodiment, the first connecting member 41 is at least provided with a sliding shaft 411 and a sliding shaft 412, and the second connecting member 42 is at least provided with a slide rail 421 and a slide rail 422. The sliding shaft 411 is connected to the slide rail 421 and can move along the slide rail 421, and the sliding shaft 412 is connected to the slide rail 422 and can move along the slide rail 422.

[0064] Both the slide rail 421 and the slide rail 422 extend linearly, and when the door body 30 seals the opening 22, the slide rail 421 is perpendicular to the plane 221 where the opening 22 is located, and the slide rail 422 is inclined relative to the plane 221 where the opening 22 is located, so that during the process of the door body 30 moving relative to the box body 20 from the state of sealing the opening 22 to opening, the door body 30 moves towards the target side 24 of the box body 20.

[0065] Specifically, the second connecting member 42 is defined with a reference circle 61, a first reference line 62, and a second reference line 63. The reference circle 61, the first reference line 62, and the second reference line 63 are coplanar. The first reference line 62 and the second reference line 63 intersect at the center O of the reference circle 61. When the door body 30 closes the opening 22, the first reference line 62 is perpendicular to the plane 221 where the opening 22 is located.

[0066] The slide rail 421 extends linearly along the first reference line 62, and the slide rail 422 extends linearly along the second reference line 63. During the process of the door body 30 moving relative to the box body 20 from the state of closing the opening 22 to being opened, the sliding shaft 411 moves along the slide rail 421, and the sliding shaft 412 moves along the slide rail 422, so that the door body 30 moves towards the target side 24 of the box body 20.

[0067] In the above manner, during the process of the door body 30 moving relative to the box body 20 from the state of closing the opening 22 to being opened under the action of the hinge assembly 40, the door body 30 moves towards the target side 24 of the box body 20, so that the degree to which the door body 30 extends beyond the outer side wall 25 of the box body 20 is reduced, and the risk of the door body 30 interfering with and colliding with external structures during the rotation process can be reduced. In other words, this embodiment allows the gap between the box body device and the external structure located beside it to be reduced, and can reach a micro-gap or even a seamless degree, which is beneficial to the box body device adopting an embedded installation method.

[0068] It should be noted that the slide rail extending along the reference line means that the center line of the slide rail coincides with the reference line.

[0069] In this embodiment, the slide rail 421 and the slide rail 422 have an intersection point. When the door body 30 closes the opening 22, both the sliding shaft 411 and the sliding shaft 412 are far away from the opening 22 relative to this intersection point, and the connection line of the sliding shaft 411 and the sliding shaft 412 is perpendicular to the slide rail 422.

[0070] Specifically, when the door body 30 closes the opening 22, at this time the door body 30 is in a closed state, the minimum distance from the central axis 414 of the sliding shaft 411 to the plane 221 where the opening 22 is located and the minimum distance from the central axis 415 of the sliding shaft 412 to the plane 221 where the opening 22 is located are both greater than or equal to the minimum distance from the center O of the reference circle 61 to the plane 221 where the opening 22 is located. And, the central axis 414 of the sliding shaft 411 is located at the intersection point of the first reference line 62 and the reference circle 61, that is, the starting point of the sliding shaft 411 is located at the intersection point of the first reference line 62 and the reference circle 61; the connection line between the intersection point of the central axis 415 of the sliding shaft 412 and the second reference line 63 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63, that is, the connection line between the starting point of the sliding shaft 412 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63.

[0071] It should be noted that the central axis 414 of the sliding shaft 411 and the central axis 415 of the sliding shaft 412 are both perpendicular to the plane of the drawing shown in the accompanying drawings of the present application. Therefore, the central axis 414 of the sliding shaft 411 and the central axis 415 of the sliding shaft 412 both appear as points in the accompanying drawings of the present application.

[0072] In the above manner, during the process in which the door body 30 is opened relative to the box body 20 from the state of sealing the opening 22 under the action of the hinge assembly 40, the door body 30 can move along a set trajectory. Specifically, as Figure 4 and Figure 5 shown, the outer edge 35 of the door body 30 can move along the trajectory A1, the first inner edge 34 can move along the trajectory A2, the second inner edge 36 can move along the trajectory A3, and the third inner edge 51 of the door seal 50 can move along the trajectory A4.

[0073] When the box body device adopts an embedded installation method, it is generally required in the industry that the distance between the box body device and the external structure beside it is less than or equal to 4 mm, and the maximum opening angle of the door body 30 needs to be greater than or equal to 90°. The door body 30 of the box body device in this embodiment moves along a set trajectory, which can ensure that the maximum distance g max from the outer edge 35 of the door body 30 exceeding the outer side wall 25 of the box body 20 is less than or equal to 4 mm, and can ensure that the maximum opening angle a max of the door body 30 is greater than or equal to 90°. Specifically, the maximum opening angle a max can reach 150°, thus meeting the requirements.

[0074] Furthermore, when the door body 30 seals the opening 22, the sliding rail 422 extends along the direction towards the pivoting side 23 and away from the box body 20, and the sliding shaft 412 is located on the side of the first reference line 62 away from the target side 24, that is, the starting point of the sliding shaft 412 is located on the side of the first reference line 62 away from the target side 24, as Figure 3 shown. Or when the door body 30 seals the opening 22, the sliding rail 422 extends along the direction towards the target side 24 and away from the box body 20, and the sliding shaft 412 is located on the side of the first reference line 62 towards the target side 24, that is, the starting point of the sliding shaft 412 is located on the side of the first reference line 62 towards the target side 24. In this way, during the process in which the door body 30 is opened relative to the box body 20 from the state of sealing the opening 22 under the action of the hinge assembly 40, it can move along a set trajectory.

[0075] Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of the second embodiment of the sliding shaft and the sliding rail of the present application.

[0076] In one embodiment, the first connecting member 41 is further provided with a sliding shaft 413, and the second connecting member 42 is further provided with a sliding rail 423. The sliding shaft 413 is connected to the sliding rail 423 and can move along the sliding rail 423. The sliding rail 423 extends linearly, and when the door body 30 closes the opening 22, the sliding rail 423 is inclined with respect to the plane 221 of the opening 22 and the sliding rail 422.

[0077] Specifically, the second connecting member 42 further defines a third reference line 64. The third reference line 64 is coplanar with the reference circle 61, and the third reference line 64 intersects the first reference line 62 and the second reference line 63 at the center O of the reference circle 61 respectively.

[0078] It should be noted that the central axis 416 of the sliding shaft 413 is perpendicular to the plane of the drawing shown in the accompanying drawings of the present application. Therefore, the central axis 416 of the sliding shaft 413 appears as a point in the accompanying drawings of the present application.

[0079] In the above manner, at any moment, at least two of the movement directions of the sliding shaft 411, the sliding shaft 412, and the sliding shaft 413 are different, which can avoid the problem that the movement directions of the sliding shaft 411, the sliding shaft 412, and the sliding shaft 413 are the same at a certain moment and cause the movement of the door body 30 to be unstable, and is beneficial to ensuring the stability of the movement of the door body 30.

[0080] In this embodiment, the sliding rails 421, 422, and 423 have an intersection point. When the door body 30 closes the opening 22, the sliding shaft 413 is far from the opening 22 relative to the intersection point, and the connection line between the sliding shaft 411 and the sliding shaft 413 is perpendicular to the sliding rail 423.

[0081] Specifically, when the door body 30 closes the opening 22, the minimum distance from the central axis 416 of the sliding shaft 413 to the plane 221 of the opening 22 is greater than or equal to the minimum distance from the center O of the reference circle 61 to the plane 221 of the opening 22, and the connection line between the intersection point of the central axis 416 of the sliding shaft 413 and the third reference line 64 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the third reference line 64, that is, the connection line between the starting point of the sliding shaft 413 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the third reference line 64. In this way, when the door body 30 is opened relative to the cabinet 20 from the state of closing the opening 22 under the action of the hinge assembly 40, the door body 30 can move along a set trajectory.

[0082] Further, when the door body 30 closes the opening 22, the sliding rail 423 extends along the direction towards the pivoting side 23 and the direction away from the cabinet 20, and the sliding shaft 413 is located on the side of the first reference line 62 away from the target side 24, that is, the starting point of the sliding shaft 413 is located on the side of the first reference line 62 away from the target side 24, as Figure 3Or when the door body 30 blocks the opening 22, the slide rail 423 extends in the direction toward the target side 24 and away from the box body 20, and the slide shaft 413 is located on the side of the first reference line 62 toward the target side 24, that is, the starting point of the slide shaft 413 is located on the side of the first reference line 62 toward the target side 24. In this way, the door body 30 can move along the set trajectory in the process of opening relative to the box body 20 from the state of blocking the opening 22 under the action of the hinge assembly 40.

[0083] Preferably, when the door body 30 is blocked at the opening 22, one of the slide rails 422 and 423 extends in a direction toward the pivot side 23 and away from the box body 20, and the other extends in a direction toward the target side 24 and away from the box body 20, that is, one of the slide shafts 412 and 413 is located on a side of the first reference line 62 away from the target side 24, and the other is located on a side of the first reference line 62 toward the target side 24, as shown in FIG. Figure 6 In other words, the slide rail 422 and the slide rail 423 are respectively located on both sides of the slide rail 421, which is beneficial to further ensure the stability of the movement of the door body 30.

[0084] Of course, in other embodiments of the present application, when the door body 30 blocks the opening 22 , the sliding shaft 412 and the sliding shaft 413 may also be located on the same side of the first reference line 62 , which is not limited here.

[0085] Please also read Figure 7 , Figure 7 It is a structural schematic diagram of the third embodiment of the sliding shaft and the sliding rail of the present application.

[0086] In an alternative embodiment, the hinge assembly 40 may only be provided with the sliding shaft 412 and the sliding rail 422 and the sliding shaft 413 and the sliding rail 423. When the door body 30 is opened relative to the box body 20 from the state of blocking the opening 22 under the action of the hinge assembly 40, the sliding shaft 412 moves along the sliding rail 422, and the sliding shaft 413 moves along the sliding rail 423, which can also guide the door body 30 to move along the set trajectory.

[0087] Vertical linear guide rail and elliptical guide rail

[0088] See also Figure 2 , Figure 8 and Figure 9 , Figure 8 is a structural schematic diagram of a fourth embodiment of the slide shaft and the slide rail of the present application, Figure 9 It is a structural schematic diagram of the fifth embodiment of the slide shaft and the slide rail of the present application. Among them, some drawings of the present application omit the width expression of the slide shaft and the slide rail, and use the central axis of the slide shaft to represent the slide shaft and the center line of the slide rail to represent the slide rail.

[0089] In one embodiment, the first connecting member 41 is provided with at least a sliding shaft 411 and a sliding shaft 412, and the second connecting member 42 is provided with at least a sliding rail 421 and a sliding rail 422. The sliding shaft 411 is connected to the sliding rail 421 and can move along the sliding rail 421, and the sliding shaft 412 is connected to the sliding rail 422 and can move along the sliding rail 422.

[0090] The sliding rail 421 extends linearly, the sliding rail 422 extends along an ellipse, and when the door body 30 closes the opening 22, the sliding rail 421 is perpendicular to the plane 221 where the opening 22 is located. The part of the sliding rail 422 away from the box body 20 is relatively farther from the pivot side 23 than the sliding rail 421, so that during the process of the door body 30 opening relative to the box body 20 from the state of closing the opening 22, the door body 30 moves towards the target side 24 of the box body 20.

[0091] Specifically, the second connecting member 42 defines a reference circle 61, a first reference line 62 and a reference ellipse 65. The reference circle 61, the first reference line 62 and the reference ellipse 65 are coplanar. The first reference line 62 passes through the center O of the reference circle 61, and the center of the reference ellipse 65 coincides with the center O. Among them, when the door body 30 closes the opening 22, the first reference line 62 is perpendicular to the plane 221 where the opening 22 is located, and the part of the reference ellipse 65 away from the box body 20 is relatively closer to the target side 24 than the first reference line 62.

[0092] The sliding rail 421 extends linearly along the first reference line 62, and the sliding rail 422 extends along the reference ellipse 65. During the process of the door body 30 opening relative to the box body 20 from the state of closing the opening 22, the sliding shaft 411 moves along the sliding rail 421, and the sliding shaft 412 moves along the sliding rail 422, so that the door body 30 moves towards the target side 24 of the box body 20.

[0093] In the above manner, during the process of the door body 30 opening relative to the box body 20 from the state of closing the opening 22 under the action of the hinge assembly 40, the door body 30 has a movement towards the target side 24 of the box body 20, so that the degree to which the door body 30 extends beyond the outer side wall 25 of the box body 20 is reduced, and the risk of the door body 30 interfering with and colliding with external structures during rotation can be reduced. In other words, this embodiment allows the gap between the box device and the external structure beside it to be reduced, and can reach the degree of a micro-gap or even a seamless gap, which is beneficial to the box device adopting an embedded installation method.

[0094] It should be noted that the sliding rail extending along the reference ellipse means that the center line of the sliding rail coincides with the reference ellipse.

[0095] In this embodiment, the sliding rail 421 passes through the center of the above ellipse. When the door body 30 closes the opening 22, both the sliding shaft 411 and the sliding shaft 412 are relatively far from the opening 22 relative to the center of the ellipse, and the sliding rail 422 extends along the direction towards the pivot side 23 and the direction close to the box body 20.

[0096] Specifically, the second connecting member 42 is further defined with a second reference line 63, a first coordinate axis X, and a second coordinate axis Y. The second reference line 63 is coplanar with the first reference line 62 and intersects the first reference line 62 at the center O of the reference circle 61. The origin of the coordinate system defined by the first coordinate axis X and the second coordinate axis Y is the center O. Wherein, when the door body 30 closes the opening 22, the first coordinate axis X is parallel to the plane 221 where the opening 22 is located, and the second coordinate axis Y is perpendicular to the plane 221 where the opening 22 is located.

[0097] Any point (x, y) of the reference ellipse 65 in this coordinate system satisfies the following relationship:

[0098] x = M / sin(θ) * cos(90° - a - θ) - R * sin(a), y = M / sin(θ) * sin(90° - a - θ)

[0099] Wherein, x is the coordinate value of this arbitrary point on the first coordinate axis X, y is the coordinate value of this arbitrary point on the second coordinate axis Y, M is the absolute value of the coordinate of the starting point of the sliding shaft 412 on the first coordinate axis X, a is the opening angle of the door body 30 relative to the box body 20, and θ is the included angle between the first reference line 62 and the second reference line 63.

[0100] When the door body 30 closes the opening 22, the minimum distance from the central axis of the sliding shaft 411 to the plane 221 where the opening 22 is located and the minimum distance from the central axis of the sliding shaft 412 to the plane 221 where the opening 22 is located are both greater than or equal to the minimum distance from the center O to the plane 221 where the opening 22 is located. And, the central axis of the sliding shaft 411 is located at the intersection of the first reference line 62 and the reference circle 61, that is, the starting point of the sliding shaft 411 is located at the intersection of the first reference line 62 and the reference circle 61; the central axis of the sliding shaft 412 is located at the intersection of the reference ellipse 65 and the second reference line 63, that is, the starting point of the sliding shaft 412 is located at the intersection of the reference ellipse 65 and the second reference line 63.

[0101] In the above manner, when the door body 30 is opened relative to the box body 20 from the state of closing the opening 22 under the action of the hinge assembly 40, the door body 30 can move along a set trajectory.

[0102] In an exemplary embodiment, when the door body 30 closes the opening 22, the sliding rail 422 bends towards the direction close to the box body 20. Specifically, the second connecting member 42 is further defined with a reference point 66. The reference point 66 is located on the second reference line 63. The connection line between the reference point 66 and the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63. The starting point of the sliding shaft 412 is relatively far from the center O of the reference circle 61 with respect to the reference point 66, and when the door body 30 closes the opening 22, the sliding rail 422 is on the side of the second reference line 63 facing the target side 24, such as Figure 2 andFigure 8 as shown

[0103] In another exemplary embodiment, when the door body 30 blocks the opening 22, the slide rail 422 bends away from the box body 20. Specifically, the starting point of the slide shaft 412 is closer to the center O of the reference circle 61 relative to the reference point 66, and when the door body 30 blocks the opening 22, the slide rail 422 is on the side of the second reference line 63 away from the target side 24, as Figure 2 and Figure 9 shown

[0104] Please refer to Figure 2 、 Figure 10 and Figure 11 , Figure 10 which is a schematic structural diagram of the sixth embodiment of the slide shaft and the slide rail of the present application, Figure 11 and

[0105]

[0106] In one embodiment, the first connector 41 is at least provided with a slide shaft 411 and a slide shaft 412, and the second connector 42 is at least provided with a slide rail 421 and a slide rail 422. The slide shaft 411 is connected to the slide rail 421 and can move along the slide rail 421, and the slide shaft 412 is connected to the slide rail 422 and can move along the slide rail 422.The slide rail 421 extends linearly, the slide rail 422 extends along an ellipse, and when the door body 30 blocks the opening 22, the slide rail 421 is perpendicular to the plane 221 where the opening 22 is located, and the part of the slide rail 422 away from the box body 20 is closer to the pivot side 23 relative to the slide rail 421, so that during the process of the door body 30 moving from the state of blocking the opening 22 to opening relative to the box body 20, the door body 30 moves towards the target side 24 of the box body 20.

[0107] Specifically, the second connector 42 defines a reference circle 61, a first reference line 62 and a reference ellipse 65. The reference circle 61, the first reference line 62 and the reference ellipse 65 are coplanar. The first reference line 62 passes through the center O of the reference circle 61, and the center of the reference ellipse 65 coincides with the center O. Among them, when the door body 30 blocks the opening 22, the first reference line 62 is perpendicular to the plane 221 where the opening 22 is located, and the part of the reference ellipse 65 away from the box body 20 is away from the target side 24 relative to the first reference line 62.

[0108] The slide rail 421 extends linearly along the first reference line 62, and the slide rail 422 extends along the reference ellipse 65. During the process of the door body 30 moving from the state of blocking the opening 22 to opening relative to the box body 20, the slide shaft 411 moves along the slide rail 421, and the slide shaft 412 moves along the slide rail 422, so that the door body 30 moves towards the target side 24 of the box body 20.

[0109] In the above manner, during the process in which the door body 30 is opened relative to the cabinet body 20 from the state of blocking the opening 22 under the action of the hinge assembly 40, the door body 30 moves towards the target side 24 of the cabinet body 20, reducing the degree to which the door body 30 extends beyond the outer side wall 25 of the cabinet body 20 and capable of reducing the risk of interference and collision with external structures during the rotation of the door body 30. In other words, this embodiment allows the gap between the cabinet device and the external structure located beside it to be reduced, and can reach a micro-gap or even a seamless state, which is beneficial for the cabinet device to adopt an embedded installation method.

[0110] In this embodiment, the slide rail 421 passes through the center of the above ellipse. When the door body 30 blocks the opening 22, both the slide shaft 411 and the slide shaft 412 are far from the opening 22 relative to the center of the ellipse, and the slide rail 422 bends in the direction towards the pivoting side 23 and away from the cabinet body 20.

[0111] Specifically, the second connecting member 42 also defines a second reference line 63, a first coordinate axis X, and a second coordinate axis Y. The second reference line 63 is coplanar with the first reference line 62 and also intersects the first reference line 62 at the center O of the reference circle 61. The origin of the coordinate system defined by the first coordinate axis X and the second coordinate axis Y is the center O. Among them, when the door body 30 blocks the opening 22, the first coordinate axis X is parallel to the plane 221 where the opening 22 is located, and the second coordinate axis Y is perpendicular to the plane 221 where the opening 22 is located.

[0112] Any point (x, y) of the reference ellipse 65 in this coordinate system satisfies the following relationship:

[0113] x = M / sin(θ) * cos(90° + a - θ) + R * sin(a), y = -M / sin(θ) * sin(90° + a - θ)

[0114] Among them, x is the coordinate value of this arbitrary point on the first coordinate axis X, y is the coordinate value of this arbitrary point on the second coordinate axis Y, M is the absolute value of the coordinate of the starting point of the slide shaft 412 on the first coordinate axis X, a is the opening angle of the door body 30 relative to the cabinet body 20, and θ is the included angle between the first reference line 62 and the second reference line 63.

[0115] When the door body 30 seals the opening 22, the minimum distance from the central axis of the sliding shaft 411 to the plane 221 where the opening 22 is located and the minimum distance from the central axis of the sliding shaft 412 to the plane 221 where the opening 22 is located are both greater than or equal to the minimum distance from the center O of the circle to the plane 221 where the opening 22 is located. Moreover, the central axis of the sliding shaft 411 is located at the intersection of the first reference line 62 and the reference circle 61, that is, the starting point of the sliding shaft 411 is located at the intersection of the first reference line 62 and the reference circle 61; the central axis of the sliding shaft 412 is located at the intersection of the reference ellipse 65 and the second reference line 63, that is, the starting point of the sliding shaft 412 is located at the intersection of the reference ellipse 65 and the second reference line 63.

[0116] In the above manner, when the door body 30 is opened relative to the box body 20 from the state of sealing the opening 22 under the action of the hinge assembly 40, the door body 30 can move along a set track.

[0117] In an exemplary embodiment, when the door body 30 seals the opening 22, the slide rail 422 is located on the side of the box body 20 away from the connection line between the sliding shaft 412 and the center of the above ellipse. Specifically, the second connecting member 42 further defines a reference point 66, the reference point 66 is on the second reference line 63, and the connection line between the reference point 66 and the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63. The starting point of the sliding shaft 412 is farther from the center O of the reference circle 61 relative to the reference point 66, and when the door body 30 seals the opening 22, the slide rail 422 is on the side of the second reference line 63 facing the target side 24, as Figure 2 and Figure 10 shown.

[0118] In another exemplary embodiment, when the door body 30 seals the opening 22, the slide rail 422 is located on the side of the box body 20 toward the connection line between the sliding shaft 412 and the center of the above ellipse. Specifically, the starting point of the sliding shaft 412 is closer to the center O of the reference circle 61 relative to the reference point 66, and when the door body 30 seals the opening 22, the slide rail 422 is on the side of the second reference line 63 away from the target side 24, as Figure 2 and Figure 11 shown.

[0119] Inclined linear slide rail is matched with elliptical slide rail

[0120] Please refer to Figure 2 、 Figure 12 and Figure 13 , Figure 12 which is a schematic structural diagram of the eighth embodiment of the sliding shaft and the slide rail of the present application, Figure 13 and

[0121] In one embodiment, the first connecting member 41 is at least provided with a sliding shaft 411 and a sliding shaft 412, and the second connecting member 42 is at least provided with a sliding rail 421 and a sliding rail 422. The sliding shaft 411 is connected to the sliding rail 421 and can move along the sliding rail 421, and the sliding shaft 412 is connected to the sliding rail 422 and can move along the sliding rail 422.

[0122] The sliding rail 421 extends linearly, the sliding rail 422 extends along an ellipse, and when the door body 30 seals the opening 22, the sliding rail 421 is inclined with respect to the plane 221 where the opening 22 is located, and the part of the sliding rail 422 away from the box body 20 is farther from the pivot side 23 than the sliding rail 421, so that in the process of the door body 30 opening relative to the box body 20 from the state of sealing the opening 22, the door body 30 moves towards the target side 24 of the box body 20.

[0123] Specifically, the second connecting member 42 defines a reference circle 61, a first reference line 62, a second reference line 63 and a reference ellipse 65. The reference circle 61, the first reference line 62, the second reference line 63 and the reference ellipse 65 are coplanar. The first reference line 62 and the second reference line 63 intersect at the center O of the reference circle 61, and the center of the reference ellipse 65 coincides with the center O. Among them, when the door body 30 seals the opening 22, the first reference line 62 is perpendicular to the plane 221 where the opening 22 is located, and the part of the reference ellipse 65 away from the box body 20 is closer to the target side 24 than the first reference line 62.

[0124] The sliding rail 421 extends linearly along the second reference line 63, and the sliding rail 422 extends along the reference ellipse 65. In the process of the door body 30 opening relative to the box body 20 from the state of sealing the opening 22, the sliding shaft 411 moves along the sliding rail 421, and the sliding shaft 412 moves along the sliding rail 422, so that the door body 30 moves towards the target side 24 of the box body 20.

[0125] In the above manner, in the process of the door body 30 opening relative to the box body 20 from the state of sealing the opening 22 under the action of the hinge assembly 40, the door body 30 has a movement towards the target side 24 of the box body 20, so that the degree to which the door body 30 extends beyond the outer side wall 25 of the box body 20 is reduced, and the risk of the door body 30 interfering with and colliding with external structures during rotation can be reduced. In other words, this embodiment allows the gap between the box body device and the external structure beside it to be reduced, and can reach a micro-gap or even a seamless level, which is beneficial to the box body device to adopt an embedded installation method.

[0126] In this embodiment, the sliding rail 421 passes through the center of the above ellipse. When the door body 30 seals the opening 22, both the sliding shaft 411 and the sliding shaft 412 are far from the opening 22 relative to the center of the ellipse, and the sliding rail 422 extends along the direction towards the pivot side 23 and the direction close to the box body 20.

[0127] Specifically, the second connecting member 42 further defines a third reference line 64, a first coordinate axis X, and a second coordinate axis Y. The third reference line 64 is coplanar with the first reference line 62 and intersects the first reference line 62 at the center O of the reference circle 61. The origin of the coordinate system defined by the first coordinate axis X and the second coordinate axis Y is the center O. Wherein, when the door body 30 seals the opening 22, the first coordinate axis X is parallel to the plane 221 where the opening 22 is located, and the second coordinate axis Y is perpendicular to the plane 221 where the opening 22 is located.

[0128] Any point (x, y) of the reference ellipse 65 in this coordinate system satisfies the following relationship:

[0129] x = M / sin(θ) * cos(90° - a - θ) - R * sin(a), y = M / sin(θ) * sin(90° - a - θ)

[0130] Wherein, x is the coordinate value of this arbitrary point on the first coordinate axis X, y is the coordinate value of this arbitrary point on the second coordinate axis Y, M is the absolute value of the coordinate of the starting point of the sliding shaft 412 on the first coordinate axis X, a is the opening angle of the door body 30 relative to the box body 20, and θ is the included angle between the first reference line 62 and the third reference line 64.

[0131] When the door body 30 seals the opening 22, the minimum distance from the central axis of the sliding shaft 411 to the plane 221 where the opening 22 is located and the minimum distance from the central axis of the sliding shaft 412 to the plane 221 where the opening 22 is located are both greater than or equal to the minimum distance from the center O to the plane 221 where the opening 22 is located. And, the connection line between the intersection point of the central axis of the sliding shaft 411 and the second reference line 63 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63, that is, the connection line between the starting point of the sliding shaft 411 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63; the central axis of the sliding shaft 412 is located at the intersection point of the reference ellipse 65 and the third reference line 64, that is, the starting point of the sliding shaft 412 is located at the intersection point of the reference ellipse 65 and the third reference line 64.

[0132] In the above manner, during the process of the door body 30 being opened relative to the box body 20 from the state of sealing the opening 22 under the action of the hinge assembly 40, the door body 30 can move along a set trajectory.

[0133] In an exemplary embodiment, when the door body 30 seals the opening 22, the slide rail 422 bends towards the box body 20. Specifically, the second connecting member 42 further defines a reference point 66. The reference point 66 is on the third reference line 64, and the connection line between the reference point 66 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the third reference line 64. The starting point of the sliding shaft 412 is farther from the center O of the reference circle 61 relative to the reference point 66, and when the door body 30 seals the opening 22, the slide rail 422 is on the side of the third reference line 64 facing the target side 24, such asFigure 2 and Figure 12 as shown

[0134] In another exemplary embodiment, when the door body 30 seals the opening 22, the slide rail 422 bends away from the box body 20. Specifically, the starting point of the sliding shaft 412 is closer to the center O of the reference circle 61 relative to the reference point 66, and when the door body 30 seals the opening 22, the slide rail 422 is on the side of the third reference line 64 away from the target side 24, as Figure 2 and Figure 13 as shown

[0135] In this embodiment, when the door body 30 seals the opening 22, the slide rail 421 extends along the direction towards the pivot side 23 and away from the box body 20, and the sliding shaft 411 is on the side of the first reference line 62 away from the target side 24, that is, the starting point of the sliding shaft 411 is on the side of the first reference line 62 away from the target side 24, as Figure 12 and Figure 13 as shown. Or when the door body 30 seals the opening 22, the slide rail 421 extends along the direction towards the target side 24 and away from the box body 20, and the sliding shaft 411 is on the side of the first reference line 62 towards the target side 24, that is, the starting point of the sliding shaft 411 is on the side of the first reference line 62 towards the target side 24. In this way, when the door body 30 opens relative to the box body 20 from the state of sealing the opening 22 under the action of the hinge assembly 40, it can move along the set track

[0136] Please refer to Figure 2 、 Figure 14 and Figure 15 , Figure 14 which is a schematic structural diagram of the tenth embodiment of the sliding shaft and the slide rail of the present application Figure 15 which is a schematic structural diagram of the eleventh embodiment of the sliding shaft and the slide rail of the present application

[0137] In one embodiment, the first connecting member 41 is at least provided with a sliding shaft 411 and a sliding shaft 412, the second connecting member 42 is at least provided with a slide rail 421 and a slide rail 422, the sliding shaft 411 is connected to the slide rail 421 and can move along the slide rail 421, and the sliding shaft 412 is connected to the slide rail 422 and can move along the slide rail 422

[0138] The slide rail 421 extends linearly, the slide rail 422 extends along an ellipse, and when the door body 30 seals the opening 22, the slide rail 421 is inclined relative to the plane 221 where the opening 22 is located, and the part of the slide rail 422 away from the box body 20 is closer to the pivot side 23 relative to the slide rail 421, so that when the door body 30 opens relative to the box body 20 from the state of sealing the opening 22, the door body 30 moves towards the target side 24 of the box body 20

[0139] Specifically, the second connecting member 42 is defined with a reference circle 61, a first reference line 62, a second reference line 63 and a reference ellipse 65. The reference circle 61, the first reference line 62, the second reference line 63 and the reference ellipse 65 are coplanar. The first reference line 62 and the second reference line 63 intersect at the center O of the reference circle 61, and the center of the reference ellipse 65 coincides with the center O. Among them, when the door body 30 seals the opening 22, the first reference line 62 is perpendicular to the plane 221 where the opening 22 is located, and the part of the reference ellipse 65 away from the box body 20 is relatively away from the target side 24 of the first reference line 62.

[0140] The slide rail 421 extends linearly along the second reference line 63, and the slide rail 422 extends along the reference ellipse 65. During the process of the door body 30 opening relative to the box body 20 from the state of sealing the opening 22, the sliding shaft 411 moves along the slide rail 421, and the sliding shaft 412 moves along the slide rail 422, so that the door body 30 moves towards the target side 24 of the box body 20.

[0141] In the above manner, during the process of the door body 30 opening relative to the box body 20 from the state of sealing the opening 22 under the action of the hinge assembly 40, the door body 30 has a movement towards the target side 24 of the box body 20, so that the degree to which the door body 30 exceeds the outer side wall 25 of the box body 20 is reduced, and the risk of interference and collision with external structures during the rotation of the door body 30 can be reduced. In other words, this embodiment allows the gap between the box device and the external structure located beside it to be reduced, and can reach a micro-gap or even a seamless degree, which is beneficial to the box device adopting an embedded installation method.

[0142] In this embodiment, the slide rail 421 passes through the center of the above ellipse. When the door body 30 seals the opening 22, both the sliding shaft 411 and the sliding shaft 412 are far away from the opening 22 relative to the center of the ellipse, and the slide rail 422 bends towards the pivoting side 23 and away from the box body 20.

[0143] Specifically, the second connecting member 42 is further defined with a third reference line 64, a first coordinate axis X and a second coordinate axis Y. The third reference line 64 is coplanar with the first reference line 62 and also intersects the first reference line 62 at the center O of the reference circle 61. The origin of the coordinate system defined by the first coordinate axis X and the second coordinate axis Y is the center O. Among them, when the door body 30 seals the opening 22, the first coordinate axis X is parallel to the plane 221 where the opening 22 is located, and the second coordinate axis Y is perpendicular to the plane 221 where the opening 22 is located.

[0144] Any point (x, y) of the reference ellipse 65 in this coordinate system satisfies the following relationship:

[0145] x = M / sin(θ) * cos(90° + a - θ) + R * sin(a), y = -M / sin(θ) * sin(90° + a - θ)

[0146] Wherein, x is the coordinate value of the arbitrary point on the first coordinate axis X, y is the coordinate value of the arbitrary point on the second coordinate axis Y, M is the absolute value of the coordinate of the starting point of the sliding shaft 412 on the first coordinate axis X, a is the opening angle of the door body 30 relative to the box body 20, and θ is the included angle between the first reference line 62 and the third reference line 64.

[0147] When the door body 30 blocks the opening 22, the minimum distance from the central axis of the sliding shaft 411 to the plane 221 where the opening 22 is located and the minimum distance from the central axis of the sliding shaft 412 to the plane 221 where the opening 22 is located are both greater than or equal to the minimum distance from the center O of the circle to the plane 221 where the opening 22 is located. And, the connection line between the intersection point of the central axis of the sliding shaft 411 and the second reference line 63 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63, that is, the connection line between the starting point of the sliding shaft 411 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63; the central axis of the sliding shaft 412 is located at the intersection point of the reference ellipse 65 and the third reference line 64, that is, the starting point of the sliding shaft 412 is located at the intersection point of the reference ellipse 65 and the third reference line 64.

[0148] In the above manner, during the process of the door body 30 being opened relative to the box body 20 from the state of blocking the opening 22 under the action of the hinge assembly 40, the door body 30 can move along a set trajectory.

[0149] In an exemplary embodiment, when the door body 30 blocks the opening 22, the slide rail 422 is located on the side of the connection line between the sliding shaft 412 and the center of the above ellipse away from the box body 20. Specifically, the second connecting member 42 further defines a reference point 66, the reference point 66 is on the third reference line 64, and the connection line between the reference point 66 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the third reference line 64. The starting point of the sliding shaft 412 is farther from the center O of the reference circle 61 relative to the reference point 66, and when the door body 30 blocks the opening 22, the slide rail 422 is on the side of the third reference line 64 facing the target side 24, as Figure 2 and Figure 14 shown.

[0150] In another exemplary embodiment, when the door body 30 blocks the opening 22, the slide rail 422 is located on the side of the connection line between the sliding shaft 412 and the center of the above ellipse facing the box body 20. Specifically, the starting point of the sliding shaft 412 is closer to the center O of the reference circle 61 relative to the reference point 66, and when the door body 30 blocks the opening 22, the slide rail 422 is on the side of the third reference line 64 away from the target side 24, as Figure 2 and Figure 15 shown.

[0151] In this embodiment, when the door body 30 seals the opening 22, the slide rail 421 extends in the direction towards the target side 24 and away from the box body 20, and the slide shaft 411 is located on the side of the first reference line 62 towards the target side 24, that is, the starting point of the slide shaft 411 is located on the side of the first reference line 62 towards the target side 24. In this way, a relatively large included angle can be ensured between the slide rail 421 and the slide rail 422, which is beneficial to ensuring the stability of the movement of the slide shaft 411 and the slide shaft 412, that is, ensuring the stable movement of the door body 30.

[0152] Elliptical slide rail cooperation

[0153] Please refer to Figure 2 、 Figure 16 and Figure 17 , Figure 16 FIG. is a schematic structural diagram of the twelfth embodiment of the slide shaft and the slide rail of the present application, Figure 17 FIG. is a schematic structural diagram of the thirteenth embodiment of the slide shaft and the slide rail of the present application.

[0154] In one embodiment, the first connecting member 41 is at least provided with a slide shaft 411 and a slide shaft 412, the second connecting member 42 is at least provided with a slide rail 421 and a slide rail 422, the slide shaft 411 is connected to the slide rail 421 and can move along the slide rail 421, and the slide shaft 412 is connected to the slide rail 422 and can move along the slide rail 422.

[0155] The slide rail 421 extends along the first reference ellipse 651, the slide rail 422 extends along the second reference ellipse 652, and when the door body 30 seals the opening 22, the part of the slide rail 421 away from the box body 20 is away from the pivot side 23, and the part of the slide rail 422 away from the box body 20 is close to the pivot side 23, so that in the process of the door body 30 moving relative to the box body 20 from the state of sealing the opening 22 to opening, the door body 30 moves towards the target side 24 of the box body 20.

[0156] It should be noted that the part of the slide rail away from the box body 20 being away from the pivot side 23 means that the part of the slide rail away from the box body 20 is away from the pivot side 23 relative to the part of the slide rail close to the box body 20. The part of the slide rail away from the box body 20 being close to the pivot side 23 means that the part of the slide rail away from the box body 20 is close to the pivot side 23 relative to the part of the slide rail close to the box body 20.

[0157] Specifically, the second connecting member 42 defines a reference circle 61, a first reference line 62, a first reference ellipse 651, and a second reference ellipse 652. The reference circle 61, the first reference line 62, the first reference ellipse 651, and the second reference ellipse 652 are coplanar. The first reference line 62 passes through the center O of the reference circle 61, and the centers of both the first reference ellipse 651 and the second reference ellipse 652 coincide with the center O. Among them, when the door body 30 closes the opening 22, the first reference line 62 is perpendicular to the plane 221 where the opening 22 is located. The part of the first reference ellipse 651 away from the box body 20 is closer to the target side 24 relative to the first reference line 62, and the part of the second reference ellipse 652 away from the box body 20 is farther from the target side 24 relative to the first reference line 62.

[0158] The slide rail 421 extends along the first reference ellipse 651, and the slide rail 422 extends along the second reference ellipse 652. During the process of the door body 30 opening relative to the box body 20 from the state of closing the opening 22, the slide shaft 411 moves along the slide rail 421, and the slide shaft 412 moves along the slide rail 422, so that the door body 30 moves towards the target side 24 of the box body 20.

[0159] In the above manner, during the process of the door body 30 opening relative to the box body 20 under the action of the hinge assembly 40 from the state of closing the opening 22, the door body 30 has a movement towards the target side 24 of the box body 20, so that the degree to which the door body 30 extends beyond the outer side wall 25 of the box body 20 is reduced, and the risk of the door body 30 interfering with and colliding with external structures during rotation can be reduced. In other words, this embodiment allows the gap between the box device and the external structure located beside it to be reduced, and can reach a micro-gap or even a seamless degree, which is beneficial for the box device to adopt an embedded installation method.

[0160] In this embodiment, when the door body 30 closes the opening 22, the slide shaft 411 is far from the opening 22 relative to the center of the first reference ellipse 651, and the slide rail 421 extends along the direction towards the pivot side 23 and the direction close to the box body 20.

[0161] Specifically, the second connecting member 42 further defines a second reference line 63, a first coordinate axis X, and a second coordinate axis Y. The second reference line 63 is coplanar with the first reference line 62 and also intersects the first reference line 62 at the center O of the reference circle 61. The origin of the coordinate system defined by the first coordinate axis X and the second coordinate axis Y is the center O. Among them, when the door body 30 closes the opening 22, the first coordinate axis X is parallel to the plane 221 where the opening 22 is located, and the second coordinate axis Y is perpendicular to the plane 221 where the opening 22 is located.

[0162] Any point (x, y) of the first reference ellipse 651 in this coordinate system satisfies the following relationship:

[0163] x=M1 / sin(θ1)*cos(90°-a-θ1)-R*sin(a), y=M1 / sin(θ1)*sin(90°-a-θ1)

[0164] Among them, x is the coordinate value of the arbitrary point on the first coordinate axis X, y is the coordinate value of the arbitrary point on the second coordinate axis Y, M1 is the absolute value of the coordinate of the starting point of the sliding shaft 411 on the first coordinate axis X, a is the opening angle of the door body 30 relative to the box body 20, and θ1 is the angle between the first reference line 62 and the second reference line 63.

[0165] When the door body 30 is blocked at the opening 22, the minimum distance from the central axis of the sliding shaft 411 to the plane 221 where the opening 22 is located is greater than or equal to the minimum distance from the center O of the reference circle 61 to the plane 221 where the opening 22 is located. In addition, the central axis of the sliding shaft 411 is located at the intersection of the first reference ellipse 651 and the second reference line 63, that is, the starting point of the sliding shaft 411 is located at the intersection of the first reference ellipse 651 and the second reference line 63.

[0166] In the above manner, when the door body 30 is opened relative to the box body 20 in a state of self-blocking the opening 22 under the action of the hinge assembly 40 , the door body 30 can move along a set trajectory.

[0167] In an exemplary embodiment, when the door body 30 is blocked at the opening 22, the slide rail 421 bends toward the direction close to the box body 20. Specifically, the second connecting member 42 further defines a first reference point 661, the first reference point 661 is located on the second reference line 63, and the line connecting the first reference point 661 and the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63. The starting point of the slide shaft 411 is away from the center O of the reference circle 61 relative to the first reference point 661, and when the door body 30 is blocked at the opening 22, the slide rail 421 is located on the side of the second reference line 63 toward the target side 24, as shown in FIG. Figure 2 and Figure 16 shown.

[0168] In another exemplary embodiment, when the door body 30 is blocked at the opening 22, the slide rail 421 is bent in a direction away from the box body 20. Specifically, the starting point of the slide shaft 411 is close to the center O of the reference circle 61 relative to the first reference point 661, and when the door body 30 is blocked at the opening 22, the slide rail 421 is on the side of the second reference line 63 away from the target side 24, as shown in FIG. Figure 2 and Figure 17 shown.

[0169] In this embodiment, when the door 30 blocks the opening 22 , the slide shaft 412 moves away from the opening 22 relative to the center of the second reference ellipse 652 , and the slide rail 422 bends toward the pivot side 23 and away from the box 20 .

[0170] Specifically, the second connecting member 42 further defines a third reference line 64. The third reference line 64 is coplanar with the first reference line 62 and intersects the first reference line 62 at the center O of the reference circle 61.

[0171] Any point (x, y) of the second reference ellipse 652 in the above coordinate system satisfies the following relationship:

[0172] x = M2 / sin(θ2) * cos(90° + a - θ2) + R * sin(a), y = -M2 / sin(θ2) * sin(90° + a - θ2)

[0173] Wherein, x is the coordinate value of the any point on the first coordinate axis X, y is the coordinate value of the any point on the second coordinate axis Y, M2 is the absolute value of the coordinate of the starting point of the sliding shaft 412 on the first coordinate axis X, a is the opening angle of the door body 30 relative to the box body 20, and θ2 is the included angle between the first reference line 62 and the third reference line 64.

[0174] When the door body 30 seals the opening 22, the minimum distance from the central axis of the sliding shaft 412 to the plane 221 where the opening 22 is located is greater than or equal to the minimum distance from the center O of the reference circle 61 to the plane 221 where the opening 22 is located. And, the central axis of the sliding shaft 412 is located at the intersection of the second reference ellipse 652 and the third reference line 64, that is, the starting point of the sliding shaft 412 is located at the intersection of the second reference ellipse 652 and the third reference line 64.

[0175] In the above manner, during the process of the door body 30 opening relative to the box body 20 from the state of sealing the opening 22 under the action of the hinge assembly 40, the door body 30 can move along a set trajectory.

[0176] In an exemplary embodiment, when the door body 30 seals the opening 22, the slide rail 422 is located on the side away from the box body 20 of the connection line between the sliding shaft 412 and the center of the second reference ellipse 652. Specifically, the second connecting member 42 further defines a second reference point 662. The second reference point 662 is on the third reference line 64, and the connection line between the second reference point 662 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the third reference line 64. The starting point of the sliding shaft 412 is farther from the center O of the reference circle 61 relative to the second reference point 662, and when the door body 30 seals the opening 22, the slide rail 422 is on the side of the third reference line 64 facing the target side 24, as Figure 2 and Figure 16 shown.

[0177] In another exemplary embodiment, when the door body 30 is blocked at the opening 22, the slide rail 422 is located on the side of the line connecting the slide shaft 412 and the center of the second reference ellipse 652 toward the box body 20. Specifically, the starting point of the slide shaft 412 is close to the center O of the reference circle 61 relative to the second reference point 662, and when the door body 30 is blocked at the opening 22, the slide rail 422 is located on the side of the third reference line 64 away from the target side 24, as shown in FIG. Figure 2 and Figure 17 shown.

[0178] See also Figure 2 , Figure 18 and Figure 19 , Figure 18 is a structural schematic diagram of the fourteenth embodiment of the sliding shaft and the sliding rail of the present application, Figure 19 It is a structural schematic diagram of the fifteenth embodiment of the sliding shaft and the sliding rail of the present application.

[0179] In one embodiment, the first connecting member 41 is provided with at least a sliding shaft 411 and a sliding shaft 412, and the second connecting member 42 is provided with at least a sliding rail 421 and a sliding rail 422, the sliding shaft 411 is connected to the sliding rail 421 and can move along the sliding rail 421, and the sliding shaft 412 is connected to the sliding rail 422 and can move along the sliding rail 422.

[0180] The slide rail 421 extends along the first reference ellipse 651, and the slide rail 422 extends along the second reference ellipse 652. When the door body 30 blocks the opening 22, the portion of the slide rail 421 away from the box body 20 and the portion of the slide rail 422 away from the box body 20 are both away from the pivot side 23, so that the door body 30 moves toward the target side 24 of the box body 20 during the process of opening relative to the box body 20 in the state of self-blocking the opening 22.

[0181] Specifically, the second connecting member 42 is defined with a reference circle 61, a first reference line 62, a first reference ellipse 651, and a second reference ellipse 652. The reference circle 61, the first reference line 62, the first reference ellipse 651, and the second reference ellipse 652 are coplanar, the first reference line 62 passes through the center O of the reference circle 61, and the center of the first reference ellipse 651 and the center of the second reference ellipse 652 both coincide with the center O. When the door body 30 blocks the opening 22, the first reference line 62 is perpendicular to the plane 221 where the opening 22 is located, and the portion of the first reference ellipse 651 away from the box body 20 and the portion of the second reference ellipse 652 away from the box body 20 are both closer to the target side 24 relative to the first reference line 62.

[0182] The slide rail 421 extends along the first reference ellipse 651, and the slide rail 422 extends along the second reference ellipse 652. When the door 30 is opened relative to the box body 20 from the state of blocking the opening 22, the slide shaft 411 moves along the slide rail 421, and the slide shaft 412 moves along the slide rail 422, so that the door 30 moves toward the target side 24 of the box body 20.

[0183] In the above - mentioned manner, when the door body 30 is opened relative to the box body 20 from the state of blocking the opening 22 under the action of the hinge assembly 40, the door body 30 moves toward the target side 24 of the box body 20, so that the degree to which the door body 30 extends beyond the outer side wall 25 of the box body 20 is reduced, and the risk of the door body 30 interfering with and colliding with external structures during rotation can be reduced. In other words, in this embodiment, the gap between the box body device and the external structure located beside it is allowed to be reduced, and it can reach a micro - gap or even a seamless state, which is beneficial to the box body device adopting an embedded installation method.

[0184] It should be noted that the first reference ellipse 651 is different from the second reference ellipse 652, that is, the degree to which the part of the first reference ellipse 651 far from the box body 20 and the part of the second reference ellipse 652 far from the box body 20 approach the target side 24 are different.

[0185] In this embodiment, when the door body 30 blocks the opening 22, the sliding shaft 411 is far from the opening 22 relative to the center of the first reference ellipse 651, and the sliding rail 421 extends along the direction toward the pivoting side 23 and the direction close to the box body 20.

[0186] Specifically, the second connecting member 42 also defines a second reference line 63, a first coordinate axis X, and a second coordinate axis Y. The second reference line 63 is coplanar with the first reference line 62 and intersects the first reference line 62 at the center O of the reference circle 61. The origin of the coordinate system defined by the first coordinate axis X and the second coordinate axis Y is the center O. Among them, when the door body 30 blocks the opening 22, the first coordinate axis X is parallel to the plane 221 where the opening 22 is located, and the second coordinate axis Y is perpendicular to the plane 221 where the opening 22 is located.

[0187] Any point (x, y) of the first reference ellipse 651 in this coordinate system satisfies the following relationship:

[0188] x = M1 / sin(θ1) * cos(90° - a - θ1) - R * sin(a), y = M1 / sin(θ1) * sin(90° - a - θ1)

[0189] Wherein, x is the coordinate value of this arbitrary point on the first coordinate axis X, y is the coordinate value of this arbitrary point on the second coordinate axis Y, M1 is the absolute value of the coordinate of the starting point of the sliding shaft 411 on the first coordinate axis X, a is the opening angle of the door body 30 relative to the box body 20, and θ1 is the included angle between the first reference line 62 and the second reference line 63.

[0190] When the door body 30 is blocked at the opening 22, the minimum distance from the central axis of the sliding shaft 411 to the plane 221 where the opening 22 is located is greater than or equal to the minimum distance from the center O of the reference circle 61 to the plane 221 where the opening 22 is located. In addition, the central axis of the sliding shaft 411 is located at the intersection of the first reference ellipse 651 and the second reference line 63, that is, the starting point of the sliding shaft 411 is located at the intersection of the first reference ellipse 651 and the second reference line 63.

[0191] In the above manner, when the door body 30 is opened relative to the box body 20 in a state of self-blocking the opening 22 under the action of the hinge assembly 40 , the door body 30 can move along a set trajectory.

[0192] In an exemplary embodiment, when the door body 30 is blocked at the opening 22, the slide rail 421 bends toward the direction close to the box body 20. Specifically, the second connecting member 42 further defines a first reference point 661, the first reference point 661 is located on the second reference line 63, and the line connecting the first reference point 661 and the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63. The starting point of the slide shaft 411 is away from the center O of the reference circle 61 relative to the first reference point 661, and when the door body 30 is blocked at the opening 22, the slide rail 421 is located on the side of the second reference line 63 toward the target side 24, as shown in FIG. Figure 2 and Figure 18 shown.

[0193] In another exemplary embodiment, when the door body 30 is blocked at the opening 22, the slide rail 421 is bent in a direction away from the box body 20. Specifically, the starting point of the slide shaft 411 is close to the center O of the reference circle 61 relative to the first reference point 661, and when the door body 30 is blocked at the opening 22, the slide rail 421 is on the side of the second reference line 63 away from the target side 24, as shown in FIG. Figure 2 and Figure 19 shown.

[0194] In this embodiment, when the door 30 blocks the opening 22 , the sliding shaft 412 is away from the opening 22 relative to the center of the second reference ellipse 652 , and the sliding rail 422 extends in a direction toward the pivot side 23 and toward the box 20 .

[0195] Specifically, the second connecting member 42 further defines a third reference line 64 , which is coplanar with the first reference line 62 and intersects with the first reference line 62 at the center O of the reference circle 61 .

[0196] Any point (x, y) of the second reference ellipse 652 in the above coordinate system satisfies the following relationship:

[0197] x=M2 / sin(θ2)*cos(90°-a-θ2)-R*sin(a), y=M2 / sin(θ2)*sin(90°-a-θ2)

[0198] Among them, x is the coordinate value of the arbitrary point on the first coordinate axis X, y is the coordinate value of the arbitrary point on the second coordinate axis Y, M2 is the absolute value of the coordinate of the starting point of the sliding shaft 412 on the first coordinate axis X, a is the opening angle of the door body 30 relative to the box body 20, and θ2 is the angle between the first reference line 62 and the third reference line 64.

[0199] When the door body 30 is blocked at the opening 22, the minimum distance from the central axis of the sliding shaft 412 to the plane 221 where the opening 22 is located is greater than or equal to the minimum distance from the center O of the reference circle 61 to the plane 221 where the opening 22 is located. In addition, the central axis of the sliding shaft 412 is located at the intersection of the second reference ellipse 652 and the third reference line 64, that is, the starting point of the sliding shaft 412 is located at the intersection of the second reference ellipse 652 and the third reference line 64.

[0200] In the above manner, when the door body 30 is opened relative to the box body 20 in a state of self-blocking the opening 22 under the action of the hinge assembly 40 , the door body 30 can move along a set trajectory.

[0201] In an exemplary embodiment, when the door body 30 is blocked at the opening 22, the slide rail 422 is bent toward the direction close to the box body 20. Specifically, the second connecting member 42 further defines a second reference point 662, the second reference point 662 is located on the third reference line 64, and the line connecting the intersection of the second reference point 662, the first reference line 62 and the reference circle 61 is perpendicular to the third reference line 64. The starting point of the slide shaft 412 is away from the center O of the reference circle 61 relative to the second reference point 662, and when the door body 30 is blocked at the opening 22, the slide rail 422 is located on the side of the third reference line 64 toward the target side 24, as shown in FIG. Figure 2 and Figure 18 shown.

[0202] In another exemplary embodiment, when the door body 30 is blocked at the opening 22, the slide rail 422 is bent in a direction away from the box body 20. Specifically, the starting point of the slide shaft 412 is close to the center O of the reference circle 61 relative to the second reference point 662, and when the door body 30 is blocked at the opening 22, the slide rail 422 is located on the side of the third reference line 64 away from the target side 24, as shown in FIG. Figure 2 and Figure 19 shown.

[0203] Preferably, the starting point of the sliding axis 411 is far away from the center O of the reference circle 61 relative to the first reference point 661, and the starting point of the sliding axis 412 is close to the center O of the reference circle 61 relative to the second reference point 662, such as Figure 18 or, the starting point of the sliding axis 411 is close to the center O of the reference circle 61 relative to the first reference point 661, and the starting point of the sliding axis 412 is far away from the center O of the reference circle 61 relative to the second reference point 662, as shown in FIG. Figure 19As shown in the figure. In this way, a relatively large included angle is formed between the slide rail 421 and the slide rail 422, which is beneficial to ensuring the stability of the movement of the slide shaft 411 and the slide shaft 412, that is, ensuring the stable movement of the door body 30.

[0204] Elliptical slide rail inflection point

[0205] Please refer to Figure 20 , Figure 20 which is a schematic structural diagram of an embodiment of the slide rail extending along the reference ellipse of the present application.

[0206] In one embodiment, the slide rail extending along the ellipse (including the reference ellipse in the above embodiment) intersects the major axis of the ellipse at the inflection point 424. There is a target point 425 on the slide rail, and the target point 425 is located on the side of the minor axis of the ellipse facing the inflection point 424. Among them, the included angle α between the connection line of any target point 425 and the inflection point 424 and the major axis of the ellipse is greater than or equal to 10°.

[0207] Through the above method, it is possible to avoid too large a turning angle of the slide rail at the inflection point 424, reduce the risk of jamming when the slide shaft passes through the inflection point 424, which is beneficial to ensuring the smooth movement of the slide shaft, that is, ensuring the smooth opening and closing of the door body; and it can also reduce the overlapping degree of the rail segments on both sides of the inflection point 424 of the slide rail, which is beneficial to ensuring the stability of the movement of the slide shaft, that is, ensuring the stable movement of the door body, and it is also convenient for the design and manufacture of the slide rail.

[0208] Slide rail included angle

[0209] Please refer to Figure 21 , Figure 21 which is a schematic structural diagram of the sixteenth embodiment of the slide shaft and the slide rail of the present application.

[0210] In one embodiment, the slide rail 421 at the position where the slide shaft 411 is located has a first tangent line P1, and the slide rail 422 at the position where the slide shaft 412 is located has a second tangent line P2, and the included angle β between the first tangent line P1 and the second tangent line P2 is greater than or equal to 10°, which is beneficial to ensuring the stability of the movement of the door body.

[0211] Slide rail setting position

[0212] Please refer to Figure 2 and Figure 22 , Figure 22 which is a schematic structural diagram of a partial part of the door body of the present application.

[0213] The following is an elaboration on the setting position of the slide rail based on the door body 30 being in the closed state.

[0214] In one embodiment, the minimum distances from the slide rail to the inner edge 31, the outer edge 32, and the side edge 33 are all greater than or equal to 6 mm. In other words, for any one of the slide rails including the slide rails 421, 422, and 423 in the above embodiments, the minimum distances from it to the inner edge 31, the outer edge 32, and the side edge 33 are all greater than or equal to 6 mm. In this way, sufficient space can be reserved for the design and manufacture of the slide rail, facilitating the engineering design and manufacture of the hinge assembly 40.

[0215] In one embodiment, different slide rails can be spaced apart from each other, that is, there is no intersection between different slide rails. Specifically, any two of the slide rails including the slide rails 421, 422, and 423 described in the above embodiments are spaced apart from each other. In this way, it can be ensured that at any time, different sliding shafts are in different slide rails, and the problem of unstable movement of the sliding shafts caused by different sliding shafts being in the same slide rail can be avoided. This embodiment is beneficial to ensuring the stability of the movement of the door body.

[0216] It should be noted that in some embodiments of the present application, the corresponding drawings show the situation where there is an intersection between different slide rails. In this case, as long as the included angle between the tangents of the slide rails where different sliding shafts are located is large enough as described in the above embodiments, the stability of the movement of the door body can also be ensured.

[0217] Reference circle size and setting position

[0218] Please refer to Figure 2 、 Figure 4 and Figure 23 , Figure 23 is Figure 2 a schematic structural diagram of another partial part of the box device shown.

[0219] The following is an elaboration on the size and setting position of the reference circle 61 based on the door body 30 being in the closed state.

[0220] In one embodiment, as the position of the reference circle 61 moves from the side edge 33 towards the target side 24 of the box body 20, the maximum distance that the outer edge 35 of the door body 30 extends beyond the outer side wall 25 of the box body 20 gradually decreases. At the same time, considering that the position of the reference circle 61 moves towards the target side 24 of the box body 20, the movement amount of the door body 30 towards the target side 24 during the opening process will increase.

[0221] In view of this, in this embodiment, the radius of the reference circle 61 is R, and the distance from the center O of the reference circle 61 to the side edge 33 is N. Among them, R ≤ N ≤ 100 mm. In this way, during the process of the door body 30 being opened under the action of the hinge assembly 40, the maximum distance that the outer side edge 35 of the door body 30 exceeds the outer side wall 25 of the box body 20 can be controlled within 4 mm required by the industry; at the same time, the movement amount of the door body 30 towards the target side 24 can be controlled within a reasonable range, reducing the risk of interference and collision between the second inner side edge 36 of the door body 30 and other structures, and also reserving sufficient space for the user to operate the door body 30. In addition, the distance from the center O of the reference circle 61 to the side edge 33 is at least equal to the radius R of the reference circle 61, so as to facilitate the design and manufacture of the upper sliding shaft and the sliding rail of the hinge assembly 40.

[0222] In one embodiment, as the position of the reference circle 61 moves from the outer edge 32 towards the inner edge 31, the movement amount of the outer side edge 35 of the door body 30 towards the box body 20 gradually increases during the opening process of the door body 30, and the risk of interference and collision between the outer side edge 35 and the box body 20 gradually rises. When the center O of the reference circle 61 approaches the opening 22 relative to the center of the side edge 33, the outer side edge 35 of the door body 30 will interfere and collide with the box body 20 during the opening process of the door body 30.

[0223] In view of this, in this embodiment, the length of the side edge 33 of the door body 30 in the first direction Z1 is D, and the distance from the center O of the reference circle 61 to the outer edge 32 is W. Among them, R ≤ W ≤ (1 / 2)D. In this way, during the process of the door body 30 being opened under the action of the hinge assembly 40, the risk of interference and collision between the outer side edge 35 of the door body 30 and the box body 20 can be reduced. In addition, the distance from the center O of the reference circle 61 to the outer edge 32 is at least equal to the radius R of the reference circle 61, so as to facilitate the design and manufacture of the upper sliding shaft and the sliding rail of the hinge assembly 40.

[0224] In one embodiment, as the position of the reference circle 61 moves from the side edge 33 towards the target side 24 of the box body 20, the movement amount of the first inner side edge 34 of the door body 30 towards the box body 20 gradually increases during the opening process of the door body 30, and the risk of interference and collision between the first inner side edge 34 and the box body 20 gradually rises.

[0225] In view of this, in this embodiment, the distance from the center O of the reference circle 61 to the side edge 33 is N, where 15 mm ≤ N ≤ 100 mm. In this way, during the process of the door body 30 being opened under the action of the hinge assembly 40, the risk of interference and collision between the first inner side edge 34 of the door body 30 and the box body 20 can be reduced. In addition, the distance from the center O of the reference circle 61 to the side edge 33 is at least 15 mm, so as to facilitate the design and manufacture of the upper sliding shaft and the sliding rail of the hinge assembly 40.

[0226] In one embodiment, as the position of the reference circle 61 moves from the outer edge 32 towards the inner edge 31, the amount of movement of the first inner edge 34 of the door body 30 towards the cabinet body 20 during the opening process of the door body 30 does not change significantly. In this case, the selection of the position of the reference circle 61 has little effect on the interference amount between the first inner edge 34 and the cabinet body 20, and more consideration is given to the design and manufacture of the hinge assembly 40.

[0227] In view of this, in this embodiment, the radius of the reference circle 61 is R, the length of the side edge 33 in the first direction Z1 is D, and the distance from the center O of the reference circle 61 to the outer edge 32 is W, where R ≤ W ≤ D. In this way, the position selection of the reference circle 61 is relatively flexible, and the sliding shaft and sliding rail can be conveniently designed and manufactured, and it can adapt to the application scenario where the maximum opening angle of the door body 30 reaches 150°.

[0228] In one embodiment, as the position of the reference circle 61 moves from the side edge 33 towards the target side 24 of the cabinet body 20, the amount of movement of the third inner edge 51 of the door seal 50 towards the cabinet body 20 during the opening process of the door body 30 gradually increases, resulting in a gradual increase in the extrusion amount of the door seal 50. To ensure the reliability of the door seal 50, it is reasonable for the industry to require that the extrusion amount of the door seal 50 be controlled within 5 mm, that is, it is required that the maximum amount of movement of the third inner edge 51 of the door seal 50 towards the cabinet body 20 during the opening process of the door body 30 is less than or equal to 5 mm.

[0229] In view of this, in this embodiment, the distance from the center O of the reference circle 61 to the side edge 33 is N, where 15 mm ≤ N ≤ 100 mm. In this way, it can be ensured that the maximum amount of movement of the third inner edge 51 of the door seal 50 towards the cabinet body 20 during the opening process of the door body 30 is less than or equal to 5 mm, which is beneficial to improving the reliability and stability of the door seal 50. In addition, the distance from the center O of the reference circle 61 to the side edge 33 is at least 15 mm, so as to facilitate the design and manufacture of the sliding shaft and sliding rail on the hinge assembly 40.

[0230] In one embodiment, as the position of the reference circle 61 moves from the outer edge 32 towards the inner edge 31, the amount of movement of the third inner edge 51 of the door seal 50 towards the cabinet body 20 during the opening process of the door body 30 does not change significantly. In this case, the selection of the position of the reference circle 61 has little effect on the extrusion amount of the door seal 50, and more consideration is given to the design and manufacture of the hinge assembly 40.

[0231] In view of this, in this embodiment, the radius of the reference circle 61 is R, the length of the side edge 33 in the first direction Z1 is D, and the distance from the center O of the reference circle 61 to the outer edge 32 is W, where R ≤ W ≤ D. In this way, the position selection of the reference circle 61 is relatively flexible, and the sliding shaft and sliding rail can be conveniently designed and manufactured, and it can adapt to the application scenario where the maximum opening angle of the door seal 50 reaches 150°.

[0232] In one embodiment, the length of the door body 30 in the first direction Z1 is H, that is, the width of the door body 30 is H, where 35 mm ≤ H ≤ 100 mm. The length of the door body 30 in the second direction Z2 is L, that is, the length of the door body 30 is L, where 300 mm ≤ L ≤ 700 mm. The radius of the reference circle 61 is R, where R = (1 / 3)H. The minimum distance from the reference circle 61 to the outer edge 32 is M, where 0 mm ≤ M ≤ 15 mm.

[0233] Based on the requirements for the size and setting position of the reference circle 61 in the above embodiments, reasonably select the size and setting position of the reference circle 61 to reasonably determine the setting positions of the sliding shaft and the sliding rail. In this way, the designed and manufactured sliding shaft and sliding rail can guide the door body 30 to move along the above-set trajectory. Specifically, the outer edge 35 of the door body 30 moves along the trajectory A1, and the maximum distance g that the outer edge 35 extends beyond the outer wall 25 of the box body 20 max can be controlled within 1 mm; the first inner edge 34 of the door body 30 moves along the trajectory A2, and the amount of movement of the first inner edge 34 towards the box body 20 is small, and the risk of interference with the box body 20 is low; the second inner edge 36 of the door body 30 moves along the trajectory A3, and the maximum distance that the second inner edge 36 extends beyond the outer wall 25 of the box body 20 can be controlled within 3 mm; the third inner edge 51 of the door seal 50 moves along the trajectory A4, and the amount of movement of the third inner edge 51 towards the box body 20 is small, that is, the extrusion amount of the door seal 50 is small.
