[0002] This application belongs to the technical field of hinges, and particularly relates to a box device.

Background Art

[0003] In the case of a box device having a door and a box, when the door is opened with respect to the box, the door may protrude from the outer wall of the box device, thus causing a problem of interference between the door and the installation environment of the box device. For example, when the box device is installed in a built-in manner, the part of the door protruding from the outer wall of the box device may interfere with the wall to be embedded.

The included angle between the first tangent line and the second tangent line is 10° or more.

[0013] In one embodiment of the present application, the second slide rail and the major axis of the ellipse intersect at the inflection point.

[0014] In one embodiment of the present application, the second slide rail has a target point located on the side towards the inflection point of the minor axis of the ellipse.

[0015] In one embodiment of the present application, the included angle between the connecting line of the target point and the inflection point and the major axis of the ellipse is 10° or more.

[0016] In one embodiment of the present application, the first slide rail and the second slide rail are separated from each other.

[0017] In one embodiment of the present application, a reference circle is defined for the second connecting component. The center line of the first slide rail passes through the center of the reference circle, and the center of the ellipse overlaps with the center of the reference circle.

When the door closes the opening, the side edge is perpendicular to the plane of the opening. Let the radius of the reference circle be R and the distance from the center of the reference circle to the side edge be N, then R ≤ N ≤ 100 mm.

[0019] In one embodiment of the present application, the end face facing the hinge assembly of the door has a side edge. When the door closes the opening, the side edge is perpendicular to the plane of the opening. Let the distance from the center of the reference circle to the side edge be N, then 15 mm ≤ N ≤ 100 mm.

[0020] In one embodiment of the present application, the end face facing the hinge assembly of the door has an inner edge and an outer edge. The inner edge and the outer edge are provided at intervals in the first direction and both extend in the second direction. The first direction is perpendicular to the second direction. When the door closes the opening, the inner edge is closer to the box body than the outer edge.

Mode for Carrying Out the Invention

[0027] To make the objectives, technical solutions and advantages of the present application clearer, the following will, in combination with the embodiments of the present application, clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application. The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0028] Basic structure Referring to FIG. 1, FIG. 1 is a structural schematic diagram of an embodiment of a conventional refrigeration device.

[0029] In the prior art, for refrigeration devices such as refrigerators, the hinge structure applied to the opening and closing of the door generally uses a single hinge axis design. For example, a hinge fixing plate 12 is provided on the box body 11 of the refrigerator 10, a hinge axis 13 is provided on the hinge fixing plate 12, a shaft hole (not shown) is provided on the door 14 of the refrigerator 10, the hinge axis 13 is inserted into the shaft hole, and the hinge axis 13 can rotate in the shaft hole, enabling the door 14 to rotate relative to the box body 11, thereby realizing the opening and closing of the door 14. As the home decoration style gradually trends towards integrity, invisibility, and simplicity, the built-in installation of the refrigerator 10 also emerges. For example, the refrigerator 10 is installed in the cabinet 15. However, due to the limitation caused by the conventional hinge structure using a single hinge axis design, during the process of the door 14 rotating relative to the box body 11, the door 14 may protrude beyond the outer wall 111 of the box body 11, and there may be a hidden risk of interference and collision between the door 14 and external structures (such as the cabinet 15, etc.) during the rotation of the door 14.

[0030] In view of this, the embodiment according to the present application provides a box body device that can reduce the degree to which the door protrudes beyond the outer wall of the box body during rotation, which will be described in detail below.

[0031] Referring to FIG. 2, FIG. 2 is a structural schematic diagram of an embodiment of the box device according to the present application.

[0032] In one embodiment, the box device may be a refrigeration device such as a refrigerator, a chest freezer, etc. Of course, the box device may also be other equipment that has a box 20 and a door 30, and the door 30 is required to be rotatable relative to the box 20. Hereinafter, a refrigerator will be described as an example of the box device, but it is only for the purpose of discussion and does not limit the specific form of the box device.

[0033] The box device includes a box 20. The box 20 is a storage medium of the box device, and the user stores articles that need to be refrigerated or frozen in the box 20. Specifically, a storage space 21 having an opening 22 is provided inside the box 20, and articles that need to be refrigerated or frozen are stored in the storage space 21 through the opening 22.

[0034] The box device further includes a door 30 for closing the opening 22 of the storage space 21. When the door 30 closes the opening 22, that is, when the door 30 is in the closed state, a sealed space for storing articles is formed inside the box 20. The door 30 is rotatably connected to the pivot side 23 of the box 20, that is, the door 30 can rotate relative to the box 20. The box 20 further includes a target side 24, and the pivot side 23 and the target side 24 are provided opposite to both sides of the opening 22.

[0035] The box body device further includes a hinge assembly 40. The hinge assembly 40 is provided on the pivot side 23 of the box body 20, and the hinge assembly 40 pivotally connects the box body 20 and the door 30, that is, realizes a rotational connection between the box body 20 and the door 30. Specifically, the hinge assembly 40 includes a first connecting component 41 provided on one of the box body 20 and the door 30, and a second connecting component 42 provided on the other. The first connecting component 41 is provided with a slide shaft, the second connecting component 42 is provided with a slide rail, and the slide shaft is movably connected to the slide rail. During the process of the door 30 rotating relative to the box body 20, the slide shaft moves along the slide rail.

[0036] It should be noted that the first connecting component 41 and the second connecting component 42 may be part of the box body 20 or the door 30, that is, the first connecting component 41 and the second connecting component 42 and the box body 20 or the door 30 may have an integrated structure. For example, when the first connecting component 41 is provided on the box body 20 and the second connecting component 42 is provided on the door 30, the first connecting component 41 and the box body 20 may have an integrated structure, and the second connecting component 42 and the door 30 may have an integrated structure. In particular, when the slide rail is in a groove shape, the surface of the door 30 is recessed to directly form the slide rail, the slide shaft is embedded in the slide rail, and at this time, the portion of the door 30 where the slide rail is located is understood to be the second connecting component 42.

[0037] In one embodiment, the end face of the door 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 provided at intervals in the first direction Z1 and both extend in the second direction Z2. When the door 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 pivot side 23, and the inner edge 31 and the outer edge 32 are connected by the side edge 33, and the side edge 33 extends in the first direction Z1. When the door 30 closes the opening 22, the side edge 33 is perpendicular to the plane 221 where the opening 22 is located.

[0038] The door 30 has a first inner edge 34 and an outer edge 35 on the pivot side 23. The first inner edge 34 and the outer edge 35 are provided at intervals in the first direction Z1 and both extend in the third direction Z3. When the door 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 is connected to the intersection of the inner edge 31 and the side edge 33, and the outer edge 35 is connected to the intersection of the outer edge 32 and the side edge 33.

[0039] On the side of the door 30 away from the pivot side 23, it further has a second inner edge 36. The second inner edge 36 extends in the third direction Z3. When the door 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. The user usually grasps the side of the door 30 away from the pivot side 23 to open the door 30.

[0040] Among them, the first direction Z1, the second direction Z2, and the third direction Z3 are perpendicular to each other. When the box body device is placed accurately, 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 provided opposite to each other in the second direction Z2. Since the third direction Z3 in FIG. 2 is perpendicular to the paper surface of the illustration, the third direction Z3 is shown as a single point in FIG. 2. Similarly, the first inner edge 34, the outer edge 35, and the second inner edge 36 are shown in the form of points in FIG. 2.

[0041] In one embodiment, the box body device further includes a door seal 50 provided on the door 30. The door 30 closes the opening 22 of the storage space 21 by the door seal 50, and when the door 30 closes the opening 22, the storage space 21 can have a good sealing effect. The door seal 50 has a third inner edge 51 on the pivot side 23. The third inner edge 51 extends along the third direction Z3, and the third inner edge 51 and the door 30 are spaced apart from each other. Similarly, the third inner edge 51 is shown in the form of a point in FIG. 2.

[0042] It should be noted that the box device of the embodiment according to the present application may adopt a single-opening type, a double-opening type, or even a design with a larger number of doors 30. The box device is provided with an independent storage space 21 corresponding to each door 30, that is, the door 30 and the storage space 21 correspond one-to-one, and the door 30 is used to close its corresponding storage space 21.

[0043] Cooperation of linear slide rails Referring to FIGS. 2 and 3, FIG. 3 is a structural schematic diagram of a first embodiment of the ride shaft and slide rail according to the present application.

[0044] In one embodiment, the first connecting component 41 is provided with at least a slide shaft 411 and a slide shaft 412, the second connecting component 42 is provided with at least a slide rail 421 and a slide rail 422, the slide shaft 411 is movably connected to the slide rail 421, and the slide shaft 412 is movably connected to the slide rail 422.

[0045] Both the slide rail 421 and the slide rail 422 extend linearly. When the door 30 closes 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 provided obliquely with respect to the plane 221 where the opening 22 is located. In the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22, the door 30 is moved toward the target side 24 of the box body 20.

[0046] Specifically, the second connecting component 42 defines 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 on the same plane. The first reference line 62 and the second reference line 63 intersect at the center O of the reference circle 61. When the door 30 closes the opening 22, the first reference line 62 is perpendicular to the plane 221 where the opening 22 is located.

[0047] 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. In the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22, the slide shaft 411 moves along the slide rail 421, the slide shaft 412 moves along the slide rail 422, and the door 30 is moved toward the target side 24 of the box body 20.

[0048] As described above, in the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22 by the action of the hinge assembly 40, the door 30 may move toward the target side 24 of the box body 20, reducing the degree to which the door 30 protrudes from the outer wall 25 of the box body 20 and reducing the risk of interference and collision of the door 30 with external structures during rotation. In other words, in this embodiment, it is allowed to reduce the gap between the box body device and the external structure located adjacent thereto to a micro-seam, and thus a seamless degree, which is advantageous for mounting the box body device in a built-in manner.

[0049] It should be noted that the fact that the slide rail extends along the reference line means that the center line of the slide rail overlaps with the reference line.

[0050] In this embodiment, the slide rail 421 and the slide rail 422 have an intersection point. When the door 30 closes the opening 22, both the slide shaft 411 and the slide shaft 412 are farther from the opening 22 than the intersection point, and the connection line between the slide shaft 411 and the slide shaft 412 is perpendicular to the slide rail 422.

[0051] Specifically, when the door 30 closes the opening 22, the door 30 is in a closed state at this time, and the minimum distance from the central axis 414 of the slide shaft 411 to the plane 221 where the opening 22 is located, and the minimum distance from the central axis 415 of the slide 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 slide 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 slide shaft 411 is located at the intersection of the first reference line 62 and the reference circle 61. The connecting line between the intersection of the central axis 415 of the slide shaft 412 and the second reference line 63 and the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63, that is, the connecting line between the starting point of the slide shaft 412 and the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63.

[0052] It should be noted that since the central axis 414 of the slide shaft 411 and the central axis 415 of the slide shaft 412 are both perpendicular to the plane of the paper shown in the accompanying drawings of the present application, the central axis 414 of the slide shaft 411 and the central axis 415 of the slide shaft 412 are all shown in the form of points in the accompanying drawings of the present application.

[0053] In the above manner, in the process of the door 30 being opened with respect to the box body 20 from the state of closing the opening 22 under the action of the hinge assembly 40, the door 30 can move along a set trajectory. Specifically, as shown in FIGS. 4 and 5, the outer edge 35 of the door 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.

[0054] When the cabinet device is installed to be built-in, in the industry, it is generally required that the distance between the cabinet device and the external structure located adjacent to it be 4 mm or less, and the maximum opening angle of the door 30 be 90° or more. When the door 30 of the cabinet device in this embodiment moves according to the set trajectory, the maximum distance g max that the outer edge 35 of the door 30 protrudes from the outer wall 25 of the cabinet 20 can be ensured to be 4 mm or less, and the maximum opening angle a max of the door 30 can be ensured to be 90° or more. Specifically, the maximum opening angle a max can reach 150°, so the requirements can be met.

[0055] Furthermore, when the door 30 closes the opening 22, the slide rail 422 extends in the direction towards the pivot side 23 or in the direction away from the cabinet 20, and the slide shaft 412 is located on the side recessed from the target side 24 of the first reference line 62. That is, as shown in FIG. 3, the starting point of the slide shaft 412 is located on the side recessed from the target side 24 of the first reference line 62. Alternatively, when the door 30 closes the opening 22, the slide rail 422 extends in the direction towards the target side 24 or in the direction away from the cabinet 20, and the slide shaft 412 is located on the side towards the target side 24 of the first reference line 62. That is, the starting point of the slide shaft 412 is located on the side towards the target side 24 of the first reference line 62. In this way, when the door 30 is opened with respect to the cabinet 20 from the state of closing the opening 22 by the action of the hinge assembly 40, it can move according to the set trajectory.

[0056] Refer to FIG. 6 in conjunction. FIG. 6 is a structural schematic diagram of a second embodiment of the slide shaft and the slide rail according to the present application.

[0057] In one embodiment, the first connecting component 41 is further provided with a slide shaft 413, the second connecting component 42 is further provided with a slide rail 423, and the slide shaft 413 is movably connected to the slide rail 423. The slide rail 423 extends linearly, and when the door 30 closes the opening 22, the slide rail 423 is provided obliquely with respect to the plane 221 where the opening 22 is located and the slide rail 422.

[0058] Specifically, the second connecting component 42 further defines a third reference line 64, the third reference line 64 is on the same plane as the reference circle 61, and intersects the centers O of the reference circle 61 with the first reference line 62 and the second reference line 63 respectively.

[0059] It should be noted that since the central axis 416 of the slide shaft 413 is perpendicular to the plane of the attached drawings of the present application, the central axis 416 of the slide shaft 413 is shown in the form of a point in the attached drawings of the present application.

[0060] In the above manner, at any point in time, at least two of the movement directions of the slide shaft 411, the slide shaft 412, and the slide shaft 413 are different, and the problem that the movement of the door 30 is unstable due to the movement directions of the slide shaft 411, the slide shaft 412, and the slide shaft 413 being the same at a certain moment can be avoided, which is advantageous for ensuring the stability of the movement of the door 30.

[0061] In this embodiment, the slide rail 421, the slide rail 422, and the slide rail 423 have intersections. When the door 30 closes the opening 22, the slide shaft 413 is farther from the opening 22 than the intersection, and the connecting line between the slide shaft 411 and the slide shaft 413 is perpendicular to the slide rail 423.

[0062] Specifically, when the door 30 closes the opening 22, the minimum distance from the central axis line 416 of the slide shaft 413 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. The connecting line between the intersection point of the central axis line 416 of the slide 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 connecting line between the starting point of the slide 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 30 is opened with respect to the box body 20 from the state of closing the opening 22 under the action of the hinge assembly 40, the door 30 can move along the set trajectory.

[0063] Furthermore, when the door 30 closes the opening 22, the slide rail 423 extends in the direction towards the pivot side 23 or the direction away from the box body 20, and the slide shaft 413 is located on the side deeper from the target side 24 of the first reference line 62. That is, as shown in FIG. 3, the starting point of the slide shaft 413 is located on the side deeper from the target side 24 of the first reference line 62. Alternatively, when the door 30 closes the opening 22, the slide rail 423 extends in the direction towards the target side 24 or the direction away from the box body 20, and the slide shaft 413 is located on the side towards the target side 24 of the first reference line 62. That is, the starting point of the slide shaft 413 is located on the side towards the target side 24 of the first reference line 62. In this way, when the door 30 is opened with respect to the box body 20 from the state of closing the opening 22 under the action of the hinge assembly 40, it can move along the set trajectory.

[0064] Preferably, when the door 30 closes the opening 22, one of the slide rails 422 and 423 extends along a direction toward the pivot side 23 or a direction away from the box body 20, and the other extends along a direction toward the target side 24 or a direction away from the box body 20. That is, as shown in FIG. 6, one of the slide shafts 412 and 413 is located on the side deeper from the target side 24 of the first reference line 62, and the other is located on the side toward the target side 24 of the first reference line 62. In other words, the slide rails 422 and 423 are located on both sides of the slide rail 421 respectively, which is advantageous for further ensuring the stability of the movement of the door 30.

[0065] Of course, in other embodiments of the present application, when the door 30 closes the opening 22, the slide shafts 412 and 413 may be located on the same side of the first reference line 62, which is not limited here.

When the door 30 is opened with respect to the box body 20 from the state of closing the opening 22 by the action of the hinge assembly 40, the slide shaft 412 moves along the slide rail 422, and the slide shaft 413 moves along the slide rail 423. Similarly, the door 30 can be guided to move along the set trajectory.

[0068] Cooperation between the vertical linear slide rail and the elliptical slide rail Referring to FIGS. 2, 8 and 9, FIG. 8 is a schematic structural diagram of a fourth embodiment of the slide shaft and the slide rail according to the present application, and FIG. 9 is a schematic structural diagram of a fifth embodiment of the slide shaft and the slide rail according to the present application. Among them, in a part of the attached drawings of the present application, the expression of the widths of the slide shaft and the slide rail is omitted, and the slide shaft is represented by using the central axis line of the slide shaft, and the slide rail is represented by using the center line of the slide rail.

[0069] In one embodiment, the first connecting component 41 is provided with at least a slide shaft 411 and a slide shaft 412, the second connecting component 42 is provided with at least a slide rail 421 and a slide rail 422, the slide shaft 411 is movably connected to the slide rail 421, and the slide shaft 412 is movably connected to the slide rail 422.

[0070] The slide rail 421 extends linearly, the slide rail 422 extends along an ellipse, when the door 30 closes 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 farther from the pivot side 23 than the slide rail 421, and in the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22, the door 30 is moved toward the target side 24 of the box body 20.

[0071] Specifically, the second connecting component 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 on the same plane. 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 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 closer to the target side 24 than the first reference line 62.

[0072] The slide rail 421 extends linearly along the first reference line 62, and the slide rail 422 extends along the reference ellipse 65. In the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22, the slide shaft 411 moves along the slide rail 421, and the slide shaft 412 moves along the slide rail 422, moving the door 30 toward the target side 24 of the box body 20.

[0073] As described above, in the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22 by the action of the hinge assembly 40, the door 30 may move toward the target side 24 of the box body 20, reducing the degree to which the door 30 protrudes beyond the outer wall 25 of the box body 20 and reducing the risk of interference and collision of the door 30 with external structures during rotation. In other words, in this embodiment, it is allowed to reduce the gap between the box body device and the external structure located adjacent thereto to a micro-seam, and thus to a seamless degree, which is advantageous for installing the box body device in a built-in manner.

[0074] It should be noted that the slide rail extending along the reference ellipse means that the center line of the slide rail overlaps with the reference ellipse.

[0075] In this embodiment, the slide rail 421 passes through the center of the above ellipse. When the door 30 closes the opening 22, both the slide shaft 411 and the slide shaft 412 are farther from the opening 22 than the center of the ellipse, and the slide rail 422 extends along the direction toward the pivot side 23 or the direction approaching the box body 20.

The second reference line 63 lies on the same plane as the first reference line 62, intersects the first reference line 62 and the center O of the reference circle 61, and 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 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.

[0077] For any point (x, y) in the coordinate system of the reference ellipse 65, the following relationship is satisfied.

[0078] x = M / sin(θ)*cos(90° - a - θ) - R*sin(a), y = M / sin(θ)*sin(90° - a - θ)

[0079] 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, M is the absolute value of the coordinate of the starting point of the slide axis 412 on the first coordinate axis X, a is the opening angle of the door 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.

And the central axis of the slide axis 411 is located at the intersection of the first reference line 62 and the reference circle 61, that is, the starting point of the slide axis 411 is located at the intersection of the first reference line 62 and the reference circle 61. The central axis of the slide axis 412 is located at the intersection of the reference ellipse 65 and the second reference line 63, that is, the starting point of the slide axis 412 is located at the intersection of the reference ellipse 65 and the second reference line 63.

[0081] As described above, in the process of the door 30 being opened with respect to the box body 20 from the state of closing the opening 22 by the action of the hinge assembly 40, the door 30 can move along a set trajectory.

[0082] In an exemplary embodiment, when the door 30 closes the opening 22, the slide rail 422 is bent in a direction close to the box body 20. Specifically, the second connecting component 42 further defines a reference point 66 located on the second reference line 63, and the connecting 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. As shown in FIGS. 2 and 8, the starting point of the slide shaft 412 is farther from the center O of the reference circle 61 than the reference point 66, and when the door 30 closes the opening 22, the slide rail 422 is located on the side facing the target side 24 of the second reference line 63.

[0083] In another exemplary embodiment, when the door 30 closes the opening 22, the slide rail 422 is bent in a direction away from the box body 20. Specifically, as shown in FIGS. 2 and 9, the starting point of the slide shaft 412 is closer to the center O of the reference circle 61 than the reference point 66, and when the door 30 closes the opening 22, the slide rail 422 is located on the side recessed from the target side 24 of the second reference line 63.

[0086] The slide rail 421 extends linearly, and the slide rail 422 extends along an ellipse. When the door 30 closes the opening 22, the slide rail 421 is perpendicular to the plane 221 where the opening 22 is located. The part of the slide rail 422 away from the box body 20 is closer to the pivot side 23 than the slide rail 421. During the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22, the door 30 is moved toward the target side 24 of the box body 20.

[0087] Specifically, for the second connecting component 42, a reference circle 61, a first reference line 62, and a reference ellipse 65 are defined. The reference circle 61, the first reference line 62, and the reference ellipse 65 are on the same plane. 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 30 closes the opening 22, the first reference line 62 is perpendicular to the plane 221 where the opening 22 is located.

[0089] In the above manner, when the door 30 is opened with respect to the box body 20 from the state where the door 30 closes the opening 22 under the action of the hinge assembly 40, the door 30 may move toward the target side 24 of the box body 20, reducing the degree to which the door 30 protrudes beyond the outer wall 25 of the box body 20 and reducing the risk of interference and collision of the door 30 with external structures during rotation. In other words, in this embodiment, it is allowed to reduce the gap between the box body device and the external structure located adjacent thereto to a micro-seam, and thus to a seamless degree, which is advantageous for installing the box body device in a built-in manner.

[0090] In this embodiment, the slide rail 421 passes through the center of the ellipse. When the door 30 closes the opening 22, both the slide shaft 411 and the slide shaft 412 are farther from the opening 22 than the center of the ellipse, and the slide rail 422 is bent in a direction approaching the pivot side 23 or a direction away from the box body 20.

[0091] Specifically, for the second connecting component 42, a second reference line 63, a first coordinate axis X, and a second coordinate axis Y are further defined. The second reference line 63 lies on the same plane as the first reference line 62 and intersects the center O of the reference circle 61 and the first reference line 62. 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 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.

[0093] x = M / sin(θ)*cos(90° + a - θ) + R*sin(a), y = -M / sin(θ)*sin(90° + a - θ)

[0094] 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, 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 30 with respect to the box body 20, and θ is the included angle between the first reference line 62 and the second reference line 63.

The portion of the slide rail 422 away from the box body 20 is closer to the pivot side 23 than the slide rail 421. In the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22, the door 30 is moved toward the target side 24 of the box body 20.

[0118] Specifically, a reference circle 61, a first reference line 62, a second reference line 63 and a reference ellipse 65 are defined in the second connecting component 42. The reference circle 61, the first reference line 62, the second reference line 63 and the reference ellipse 65 are on the same plane. 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.

[0119] The slide rail 421 extends linearly along the second reference line 63, and the slide rail 422 extends along the reference ellipse 65. In the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22, the slide shaft 411 moves along the slide rail 421, the slide shaft 412 moves along the slide rail 422, and the door 30 is moved toward the target side 24 of the box body 20.

[0120] As described above, in the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22 by the action of the hinge assembly 40, the door 30 may move toward the target side 24 of the box body 20, reducing the degree to which the door 30 protrudes beyond the outer wall 25 of the box body 20 and reducing the risk of interference and collision of the door 30 with external structures during rotation. In other words, in this embodiment, it is allowed to reduce the gap between the box body device and the external structure located adjacent thereto to a micro-seam, and thus a seamless degree, which is advantageous for installing the box body device in a built-in manner.

[0121] In this embodiment, the slide rail 421 passes through the center of the ellipse. When the door 30 closes the opening 22, both the slide shaft 411 and the slide shaft 412 are farther from the opening 22 than the center of the ellipse, and the slide rail 422 is bent in a direction approaching the pivot side 23 or a direction away from the box body 20.

Among them, when the door 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.

[0123] Any point (x, y) in the coordinate system of the reference ellipse 65 satisfies the following relationship.

[0124] x = M / sin(θ) * cos(90° + a - θ) + R * sin(a), y = -M / sin(θ) * sin(90° + a - θ)

[0125] 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, M is the absolute value of the coordinate on the first coordinate axis X at the starting point of the slide axis 412, a is the opening angle of the door 30 with respect to the box body 20, and θ is the included angle between the first reference line 62 and the third reference line 64.

[0126] When the door 30 closes the opening 22, the minimum distance from the central axis of the slide axis 411 to the plane 221 where the opening 22 is located, and the minimum distance from the central axis of the slide axis 412 to the plane 221 where the opening 22 is located are both not less than the minimum distance from the center O to the plane 221 where the opening 22 is located. And the connecting line between the intersection of the central axis of the slide axis 411 and the second reference line 63 and the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63, that is, the connecting line between the starting point of the slide axis 411 and the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63. The central axis of the slide axis 412 is located at the intersection of the reference ellipse 65 and the third reference line 64, that is, the starting point of the slide axis 412 is located at the intersection of the reference ellipse 65 and the third reference line 64.

[0127] In the above way, in the process of the door 30 being 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 30 can move along the set trajectory.

[0128] In an exemplary embodiment, when the door 30 closes the opening 22, the slide rail 422 is located on the side further back from the box body 20 along the connecting line between the slide shaft 412 and the center of the ellipse. Specifically, for the second connecting component 42, a reference point 66 is further defined, and the reference point 66 is located on the third reference line 64. The connecting 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. As shown in FIGS. 2 and 14, the starting point of the slide shaft 412 is farther from the center O of the reference circle 61 than the reference point 66. When the door 30 closes the opening 22, the slide rail 422 is located on the side facing the target side 24 of the third reference line 64.

[0129] In another exemplary embodiment, when the door 30 closes the opening 22, the slide rail 422 is located on the side facing the box body 20 along the connecting line between the slide shaft 412 and the center of the ellipse. Specifically, as shown in FIGS. 2 and 15, the starting point of the slide shaft 412 is closer to the center O of the reference circle 61 than the reference point 66. When the door 30 closes the opening 22, the slide rail 422 is located on the side farther back from the target side 24 of the third reference line 64.

[0130] In this embodiment, when the door 30 closes the opening 22, the slide rail 421 extends in the direction towards the target side 24 or the direction away from the box body 20. The slide shaft 411 is located on the side facing the target side 24 of the first reference line 62, that is, the starting point of the slide shaft 411 is located on the side facing the target side 24 of the first reference line 62. In this way, a 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 movements of the slide shaft 411 and the slide shaft 412, that is, ensuring the stable movement of the door 30.

[0131] Cooperation of the elliptical slide rail Referring to FIGS. 2, 16 and 17, FIG. 16 is a structural schematic diagram of a twelfth embodiment of the slide shaft and the slide rail according to the present application, and FIG. 17 is a structural schematic diagram of a thirteenth embodiment of the slide shaft and the slide rail according to the present application.

[0132] In one embodiment, the first connecting component 41 is provided with at least a slide shaft 411 and a slide shaft 412, the second connecting component 42 is provided with at least a slide rail 421 and a slide rail 422, the slide shaft 411 is movably connected to the slide rail 421, and the slide shaft 412 is movably connected to the slide rail 422.

[0133] The slide rail 421 extends along a first reference ellipse 651, the slide rail 422 extends along a second reference ellipse 652. When the door 30 closes the opening 22, the portion of the slide rail 421 away from the box body 20 is away from the pivot side 23, and the portion of the slide rail 422 away from the box body 20 is close to the pivot side 23. In the process of the door 30 being opened relative to the box body 20 from the state where the door 30 closes the opening 22, the door 30 is moved toward the target side 24 of the box body 20.

[0134] It should be noted that the portion of the slide rail away from the box body 20 being away from the pivot side 23 means that the portion of the slide rail away from the box body 20 is farther from the pivot side 23 than the portion of the slide rail close to the box body 20, and the portion of the slide rail away from the box body 20 being close to the pivot side 23 means that the portion of the slide rail away from the box body 20 is closer to the pivot side 23 than the portion of the slide rail close to the box body 20.

[0135] Specifically, for the second connecting component 42, a reference circle 61, a first reference line 62, a first reference ellipse 651, and a second reference ellipse 652 are defined. The reference circle 61, the first reference line 62, the first reference ellipse 651, and the second reference ellipse 652 are on the same plane. The first reference line 62 passes through the center O of the reference circle 61, and the centers of the first reference ellipse 651 and the second reference ellipse 652 both overlap with the center O. Among them, when the door 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 that is away from the box body 20 is closer to the target side 24 than the first reference line 62, and the part of the second reference ellipse 652 that is away from the box body 20 is farther from the target side 24 than the first reference line 62.

[0136] The slide rail 421 extends along the first reference ellipse 651, and the slide rail 422 extends along the second reference ellipse 652. In the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22, the slide shaft 411 moves along the slide rail 421, the slide shaft 412 moves along the slide rail 422, and the door 30 is moved toward the target side 24 of the box body 20.

[0137] As described above, in the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22 under the action of the hinge assembly 40, the door 30 may move toward the target side 24 of the box body 20, reducing the degree to which the door 30 protrudes beyond the outer wall 25 of the box body 20 and reducing the risk of interference and collision of the door 30 with external structures during rotation. In other words, in this embodiment, it is allowed to reduce the gap between the box body device and the external structure located adjacent thereto to a micro-seam, and thus a seamless level, which is advantageous for installing the box body device in a built-in manner.

[0138] In this embodiment, when the door 30 closes the opening 22, the slide shaft 411 is farther from the opening 22 than the center of the first reference ellipse 651, and the slide rail 421 extends in the direction toward the pivot side 23 or in the direction close to the box body 20.

[0139] Specifically, for the second connecting component 42, a second reference line 63, a first coordinate axis X, and a second coordinate axis Y are further defined. The second reference line 63 lies in the same plane as the first reference line 62, intersects the first reference line 62 and the center O of the reference circle 61, and the origin of the coordinate system defined by the first coordinate axis X and the second coordinate axis Y is the center O. In particular, when the door 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.

[0140] Any point (x, y) of the first reference ellipse 651 in this coordinate system satisfies the following relationship.

[0141] x = M 1 / sin(θ 1 ) * cos(90° - a - θ 1 ) - R * sin(a), y = M 1 / sin(θ 1 ) * sin(90° - a - θ 1 )

[0142] 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, M 1 is the absolute value of the coordinate of the starting point of the slide axis 411 on the first coordinate axis X, a is the opening angle of the door 30 with respect to the box body 20, and θ 1 is the included angle between the first reference line 62 and the second reference line 63.

[0143] When the door 30 closes the opening 22, the minimum distance from the central axis of the slide axis 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. And the central axis of the slide axis 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 slide axis 411 is located at the intersection of the first reference ellipse 651 and the second reference line 63.

[0144] As described above, in the process of the door 30 being opened with respect to the box body 20 from the state of closing the opening 22 under the action of the hinge assembly 40, the door 30 can move along a set trajectory.

[0145] In an exemplary embodiment, when the door 30 closes the opening 22, the slide rail 421 is bent in a direction approaching the box body 20. Specifically, the second connecting component 42 further defines a first reference point 661 located on the second reference line 63, and the connecting line between the first reference point 661 and the intersection point of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63. As shown in FIGS. 2 and 16, the starting point of the slide shaft 411 is farther from the center O of the reference circle 61 than the first reference point 661, and when the door 30 closes the opening 22, the slide rail 421 is located on the side facing the target side 24 of the second reference line 63.

[0147] In this embodiment, when the door 30 closes the opening 22, the slide shaft 412 is farther from the opening 22 than the center of the second reference ellipse 652, and the slide rail 422 is bent in a direction approaching the pivot side 23 or a direction away from the box body 20.

[0148] Specifically, the second connecting component 42 further defines a third reference line 64, and the third reference line 64 is on the same plane as the first reference line 62 and intersects the center O of the reference circle 61 and the first reference line 62.

[0149] Any point (x, y) in the above coordinate system of the second reference ellipse 652 satisfies the following relationship.

[0150] x = M 2 / sin(θ 2 ) * cos(90° + a - θ 2 ) + R * sin(a), y = -M 2 / sin(θ 2 ) * sin(90° + a - θ 2 )

[0151] Among them, x is the coordinate value on the first coordinate axis X of the arbitrary point, y is the coordinate value on the second coordinate axis Y of the arbitrary point, M 2 is the absolute coordinate value on the first coordinate axis X of the starting point of the slide axis 412, a is the opening angle of the door 30 with respect to the box body 20, and θ 2 is the included angle between the first reference line 62 and the third reference line 64.

[0152] When the door 30 closes the opening 22, the minimum distance from the central axis of the slide axis 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 slide axis 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 slide axis 412 is located at the intersection of the second reference ellipse 652 and the third reference line 64.

[0153] In the above manner, when the door 30 is opened from the state of closing the opening 22 with respect to the box body 20 by the action of the hinge assembly 40, the door 30 can move along the set trajectory.

[0154] In an exemplary embodiment, when the door 30 closes the opening 22, the slide rail 422 is located on the side further back from the box body 20 along the connecting line between the slide shaft 412 and the center of the second reference ellipse 652. Specifically, the second connecting component 42 further defines a second reference point 662 located on the third reference line 64. The connecting 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. As shown in FIGS. 2 and 16, the starting point of the slide shaft 412 is farther from the center O of the reference circle 61 than the second reference point 662. When the door 30 closes the opening 22, the slide rail 422 is located on the side facing the target side 24 of the third reference line 64.

[0155] In another exemplary embodiment, when the door 30 closes the opening 22, the slide rail 422 is located on the side facing the box body 20 along the connecting line between the slide shaft 412 and the center of the second reference ellipse 652.

When the door 30 closes the opening 22, the slide rail 422 is located on the side further back from the target side 24 of the third reference line 64.

[0156] Referring to FIGS. 2, 18, and 19, FIG. 18 is a structural schematic diagram of a fourteenth embodiment of the slide shaft and the slide rail according to the present application, and FIG. 19 is a structural schematic diagram of a fifteenth embodiment of the slide shaft and the slide rail according to the present application.

[0157] In one embodiment, the first connecting component 41 is at least provided with a slide shaft 411 and a slide shaft 412, the second connecting component 42 is at least provided with a slide rail 421 and a slide rail 422, the slide shaft 411 is movably connected to the slide rail 421, and the slide shaft 412 is movably connected to the slide rail 422.

[0158] 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 closes the opening 22, the portions of the slide rail 421 and the slide rail 422 that are away from the box body 20 are both away from the pivot side 23. During the process of the door 30 being opened with respect to the box body 20 from the state where the door 30 closes the opening 22, the door 30 is moved toward the target side 24 of the box body 20.

[0159] Specifically, for the second connecting component 42, the reference circle 61, the first reference line 62, the first reference ellipse 651, and the second reference ellipse 652 are defined. The reference circle 61, the first reference line 62, the first reference ellipse 651, and the second reference ellipse 652 are on the same plane.

In other words, in this embodiment, it is allowed to reduce the gap between the box body device and the external structure located adjacent thereto to a micro-seam, and thus to a seamless level, which is advantageous for installing the box body device in a built-in manner.

[0162] It should be noted that the first reference ellipse 651 and the second reference ellipse 652 are different, that is, the degree of proximity to the target side 24 of the part of the first reference ellipse 651 away from the box body 20 and the part of the second reference ellipse 652 away from the box body 20 is different.

[0169] As described above, when the door 30 is opened with respect to the box body 20 from the closed state of the opening 22 by the action of the hinge assembly 40, the door 30 can move along the set trajectory.

[0170] In an exemplary embodiment, when the door 30 closes the opening 22, the slide rail 421 is bent in a direction approaching the box body 20. Specifically, the second connecting component 42 further defines a first reference point 661 located on the second reference line 63, and the connecting line between 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.

[0173] Specifically, for the second connecting component 42, a third reference line 64 is further defined, and the third reference line 64 is on the same plane as the first reference line 62 and intersects the center O of the reference circle 61 and the first reference line 62.

[0174] Any point (x, y) in the coordinate system of the second reference ellipse 652 satisfies the following relationship.

[0175] x = M 2 / sin(θ 2 ) * cos(90° - a - θ 2 ) - R * sin(a), y = M 2 / sin(θ 2 ) * sin(90° - a - θ 2 )

[0176] 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, M 2 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 30 with respect to the box body 20, and θ 2 is the included angle between the first reference line 62 and the third reference line 64.

[0177] When the door 30 closes the opening 22, the minimum distance from the central axis of the slide 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 slide 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 slide shaft 412 is located at the intersection of the second reference ellipse 652 and the third reference line 64.

[0178] As described above, when the door 30 is opened with respect to the box body 20 from the state of closing the opening 22 by the action of the hinge assembly 40, the door 30 can move along the set trajectory.

[0179] In an exemplary embodiment, when the door 30 closes the opening 22, the slide rail 422 is bent in a direction close to the box body 20. Specifically, the second connecting part 42 further defines a second reference point 662 located on the third reference line 64, and the connecting line between the second reference point 662 and the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the third reference line 64. As shown in FIGS. 2 and 18, the starting point of the slide shaft 412 is farther from the center O of the reference circle 61 than the second reference point 662, and when the door 30 closes the opening 22, the slide rail 422 is located on the side facing the target side 24 of the third reference line 64.

[0180] In another exemplary embodiment, when the door 30 closes the opening 22, the slide rail 422 is bent in a direction away from the box body 20. Specifically, as shown in FIGS. 2 and 19, the starting point of the slide shaft 412 is closer to the center O of the reference circle 61 than the second reference point 662, and when the door 30 closes the opening 22, the slide rail 422 is located on the side recessed from the target side 24 of the third reference line 64.

In this way, a large included angle is formed between the slide rail 421 and the slide rail 422, which is advantageous for ensuring the movement stability of the slide shaft 411 and the slide shaft 412, that is, ensuring that the door 30 moves stably.

[0182] Inflection point of the elliptical slide rail Referring to FIG. 20, FIG. 20 is a structural schematic diagram of an embodiment of a slide rail extending along the reference ellipse according to the present application.

[0183] In one embodiment, the slide rail extending along the ellipse (including the reference ellipse in the above embodiment) intersects with the major axis of the ellipse at the inflection point 424. The slide rail has a target point 425 located on the side facing the inflection point 424 of the minor axis of the ellipse. Among them, the included angle α between the connecting line of any target point 425 and the inflection point 424 and the major axis of the ellipse is all 10° or more.

[0184] In the above way, it is possible to avoid the rotation angle of the slide rail becoming too large at the position of the inflection point 424, reduce the risk of the slide shaft not moving when passing through the inflection point 424, and help ensure that the slide shaft moves smoothly, that is, ensure that the door opens and closes smoothly. In addition, the overlapping degree of the rail segments of the slide rail located on both sides of the inflection point 424 can be reduced, which is advantageous for ensuring the movement stability of the slide shaft, that is, ensuring that the door moves stably, and can also provide convenience for the design and manufacture of the slide rail.

[0185] Included angle of the slide rail Referring to FIG. 21, FIG. 21 is a structural schematic diagram of a 16th embodiment of the slide shaft and the slide rail according to the present application.

[0188] Hereinafter, based on the case where the door 30 is in the closed state, the installation position of the slide rail will be described.

[0189] 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 6 mm or more. In other words, the minimum distances from any one of the slide rails including the slide rail 421, the slide rail 422, and the slide rail 423 in the above embodiment to the inner edge 31, the outer edge 32, and the side edge 33 are all 6 mm or more. In this way, sufficient space can be ensured for the design and manufacture of the slide rail, and convenience is provided for the process design and manufacture of the hinge assembly 40.

[0190] In one embodiment, different slide rails may be spaced apart from each other, that is, different slide rails do not intersect. Specifically, any two of the slide rails including the slide rail 421, the slide rail 422, and the slide rail 423 described in the above embodiment are spaced apart from each other. In this way, at any time, it can be ensured that different slide shafts are all located on different slide rails, and the problem that different slide shafts are located on the same slide rail and the movement of the slide shaft becomes unstable can be avoided. This embodiment is advantageous for ensuring the stability of the movement of the door.

[0191] It should be noted that in some embodiments of the present application, the corresponding attached drawings show the case where different slide rails intersect. In this case, as described in the above embodiments, if there is a sufficiently large included angle between the tangents of the slide rails where different slide axes are located, the stability of the door movement can be ensured as well.

[0192] Size and installation position of the reference circle Referring to FIGS. 2, 4, and 23, FIG. 23 is a structural schematic diagram of another part of the box body device shown in FIG. 2.

[0193] Hereinafter, based on the case where the door 30 is in the closed state, the size and installation position of the reference circle 61 will be described.

[0194] 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 30 protrudes beyond the outer wall 25 of the box body 20 gradually decreases. At the same time, when the position of the reference circle 61 moves towards the target side 24 of the box body 20, it is conceivable that the amount of movement of the door 30 towards the target side 24 increases during the opening process.

[0195] In view of this, if the radius of the reference circle 61 in this embodiment is R and the distance from the center O of the reference circle 61 to the side edge 33 is N, then R≤N≤100 mm. In this way, it can be ensured that during the process of the door 30 being opened by the action of the hinge assembly 40, the maximum distance that the outer edge 35 of the door 30 protrudes beyond the outer wall 25 of the box body 20 is controlled within 4 mm required in the industry. At the same time, the amount of movement of the door 30 towards the target side 24 can be controlled within a reasonable range, reducing the risk of interference and collision between the second inner edge 36 of the door 30 and other structures, and ensuring sufficient space for the user to operate to open the door 30. It should be noted that 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, which provides convenience for the design and manufacture of the slide axis and slide rail on the hinge assembly 40.

[0196] In one embodiment, as the position of the reference circle 61 moves from the outer edge 32 toward the inner edge 31, the amount of movement of the outer edge 35 of the door 30 toward the box body 20 gradually increases during the process of opening the door 30, and the risk of interference or collision between the outer edge 35 and the box body 20 gradually increases. When the center O of the reference circle 61 is closer to the opening 22 than the center of the side edge 33, the outer edge 35 of the door 30 interferes with and collides with the box body 20 during the process of opening the door 30.

[0197] In view of this, in this embodiment, if the length of the side edge 33 of the door 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, then R≤W≤(1 / 2)D. In this way, during the process of opening the door 30 under the action of the hinge assembly 40, the risk of interference and collision between the outer edge 35 of the door 30 and the box body 20 can be reduced. Note that 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, which provides convenience for the design and manufacture of the slide shaft and slide rail on the hinge assembly 40.

[0198] In one embodiment, as the position of the reference circle 61 moves from the side edge 33 toward the target side 24 of the box body 20, the amount of movement of the first inner edge 34 of the door 30 toward the box body 20 gradually increases during the process of opening the door 30, and the risk of interference and collision between the first inner edge 34 and the box body 20 gradually increases.

[0199] In view of this, in this embodiment, if the distance from the center O of the reference circle 61 to the side edge 33 is N, then 15mm≤N≤100mm. In this way, during the process of opening the door 30 under the action of the hinge assembly 40, the risk of interference and collision between the first inner edge 34 of the door 30 and the box body 20 can be reduced. Note that the distance from the center O of the reference circle 61 to the side edge 33 is at least 15mm, which provides convenience for the design and manufacture of the slide shaft and slide rail on the hinge assembly 40.

[0200] In one embodiment, as the position of the reference circle 61 moves from the outer edge 32 towards the inner edge 31, during the process of opening the door 30, the amount of movement of the first inner edge 34 of the door 30 towards the box body 20 does not change significantly. In this case, the selection of the position of the reference circle 61 has little impact on the interference amount between the first inner edge 34 and the box body 20, and more considerations are given to the design and manufacture of the hinge assembly 40.

[0201] In view of this, in this embodiment, if 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, then R ≤ W ≤ D. In this way, the selection of the position of the reference circle 61 is flexible, which is convenient for the design and manufacture of the slide shaft and the slide rail, and can be adapted to the application scenario where the maximum opening angle of the door 30 reaches 150°.

[0202] 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, during the process of opening the door 30, the amount of movement of the third inner edge 51 of the door seal 50 towards the box body 20 gradually increases, and the pressing amount of the door seal 50 gradually increases. In order to ensure the reliability of the door seal 50, it is reasonable in the industry to control the pressing amount of the door seal 50 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 box body 20 during the process of opening the door 30 is 5 mm or less.

[0203] In view of this, in this embodiment, if the distance from the center O of the reference circle 61 to the side edge 33 is N, then 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 box body 20 during the process of opening the door 30 is 5 mm or less, which is advantageous for enhancing the reliability and stability of the door seal 50. Note that the distance from the center O of the reference circle 61 to the side edge 33 is at least 15 mm, which provides convenience for the design and manufacture of the slide shaft and the slide rail on the hinge assembly 40.

[0204] 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 box body 20 during the process of opening the door 30 does not change significantly. In this case, the selection of the position of the reference circle 61 has little impact on the pressing amount on the door seal 50, and more considerations are given to the design and manufacture of the hinge assembly 40.

[0205] In view of this, in this embodiment, if 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, then R ≤ W ≤ D. In this way, the selection of the position of the reference circle 61 is flexible, which is convenient for the design and manufacture of the slide shaft and the slide rail, and can be adapted to the application scenario where the maximum opening angle of the door seal 50 reaches 150°.

[0206] In one embodiment, if the length of the door 30 in the first direction Z1 is H, that is, the width of the door 30 is H, then 35 mm ≤ H ≤ 100 mm. If the length of the door 30 in the second direction Z2 is L, that is, the length of the door 30 is L, then 300 mm ≤ L ≤ 700 mm. If the radius of the reference circle 61 is R, then R = (1 / 3)H. If the minimum distance from the reference circle 61 to the outer edge 32 is M, then 0 mm ≤ M ≤ 15 mm.

[0207] Summarize the requirements for the size and installation position of the reference circle 61 in the above embodiment. By reasonably selecting the size and installation position of the reference circle 61, the installation positions of the slide shaft and the slide rail can be reasonably determined. The slide shaft and the slide rail obtained by designing and manufacturing in this way can guide the door 30 to move according to the above-set trajectory. Specifically, the outer edge 35 of the door 30 moves along the trajectory A1, and the maximum distance g that the outer edge 35 protrudes from the outer wall 25 of the box body 20 maxIt can be controlled within 1 mm. The first inner edge 34 of the door 30 moves along the locus A2, 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 30 moves along the locus A3, and the maximum distance that the second inner edge 36 protrudes 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 locus A4, and the amount of movement of the third inner edge 51 towards the box body 20 is small, that is, the pressing amount of the door seal 50 is small.
