Description

Technical Field

[0001] This application relates to the field of hinge technology, and in particular to a box-type device. Background Technology

[0002] For enclosure devices with doors and enclosures, when the door is opened relative to the enclosure, it may extend beyond the outer wall of the enclosure device. This can cause interference between the door and the installation environment of the enclosure device. For example, in the case of recessed installation of the enclosure device, the portion of the door extending beyond the outer wall of the enclosure device may interfere with the embedded wall. Summary of the Invention

[0003] In view of this, the main technical problem to be solved by this application is to provide a box device that can reduce the risk of interference and collision during the rotation of the door.

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide a box-like device. The box-like device includes a box body with an internal accommodating space having an opening. The box-like device also includes a door for sealing the opening. The box-like device further includes a hinge assembly located on the pivot side of the box body and pivotally connecting the box body and the door. The hinge assembly includes a first connecting member and a second connecting member. The first connecting member is located on one of the box body and the door, and the second connecting member is located on the other. The first connecting member has at least a first sliding shaft and a second sliding shaft, and the second connecting member has at least a first slide rail and a second slide rail. The first sliding shaft is connected to the first slide rail and is movable along the first slide rail, and the second sliding shaft is connected to the second slide rail and is movable along the second slide rail.

[0016] In one embodiment of this application, the second connector defines a reference circle, the centerline of the first slide rail passes through the center of the reference circle, and the center of the ellipse coincides with the center of the reference circle; the end face of the door facing the hinge assembly has an inner edge, an outer edge, and a side edge, the inner edge and the outer edge are spaced apart along a first direction and both extend along a second direction, the inner edge and the outer edge are connected by the side edge, the side edge extends along the first direction, wherein the first direction is perpendicular to the second direction, and when the door is blocked at the opening, the inner edge is closer to the box body than the outer edge; the radius of the reference circle is R, the length of the side edge in the first direction is D, and the distance from the center of the reference circle to the outer edge is W, wherein R≤W≤D.

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] Basic structure

[0045] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of a prior art refrigeration device.

[0046] In the prior art, the hinge structure used for opening and closing the door of refrigeration equipment such as refrigerators typically adopts a single hinge shaft design. For example, the refrigerator body 11 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 body 11, thereby realizing the opening and closing of the door body 14.

[0047] As home decoration styles gradually trend towards integration, concealment, and simplicity, the built-in installation of refrigerator 10 has emerged accordingly, such as embedding refrigerator 10 into cabinet 15. However, due to the limitation of the existing hinge structure using a single hinge axis design, the door 14 may extend beyond the outer wall 111 of the cabinet 11 during rotation relative to the cabinet body 11. This leads to the potential for interference or collision between the door 14 and external structures (such as cabinet 15) during rotation.

[0048] In view of this, embodiments of this application provide a housing device that can reduce the extent to which the door extends beyond the outer wall of the housing during rotation, as described in detail below.

[0049] Please see Figure 2 , Figure 2 This is a structural schematic diagram of an embodiment of the housing device of this application.

[0050] In one embodiment, the cabinet device can be a refrigeration device such as a refrigerator or freezer. Of course, the cabinet device can also be other devices having a cabinet 20 and a door 30, and requiring the door 30 to be able to rotate relative to the cabinet 20. The following description uses a refrigerator as an example of the cabinet device only for illustrative purposes and does not limit the specific form of the cabinet device.

[0051] The enclosure device includes an enclosure 20. The enclosure 20 is the storage medium of the enclosure device, in which users store items that need to be refrigerated or frozen. Specifically, the enclosure 20 has an internal receiving space 21 with an opening 22 through which items that need to be refrigerated or frozen are stored.

[0052] The enclosure also includes a door 30, which seals the opening 22 of the receiving space 21. When the door 30 seals the opening 22, i.e., when the door 30 is closed, a relatively enclosed space is formed inside the enclosure 20 for storing items. The door 30 is rotatably connected to the pivot side 23 of the enclosure 20, meaning the door 30 can rotate relative to the enclosure 20. The enclosure 20 also has a target side 24, with the pivot side 23 and the target side 24 positioned opposite each other on either side of the opening 22.

[0053] The housing assembly also includes a hinge assembly 40. The hinge assembly 40 is located on the pivot side 23 of the housing 20 and pivotally connects the housing 20 and the door 30, thus enabling a rotational connection between the housing 20 and the door 30. Specifically, the hinge assembly 40 includes a first connector 41 and a second connector 42. The first connector 41 is located on one of the housing 20 and the door 30, and the second connector 42 is located on the other. The first connector 41 has a sliding shaft, and the second connector 42 has a sliding rail. The sliding shaft is connected to the sliding rail and can move along the sliding rail. During the rotation of the door 30 relative to the housing 20, the sliding shaft moves along the sliding rail.

[0054] It should be noted that the first connector 41 and the second connector 42 can be part of the housing 20 and the door 30, that is, the first connector 41 and the second connector 42 can be an integral structure with the housing 20 and the door 30. For example, when the first connector 41 is located in the housing 20 and the second connector 42 is located in the door 30, the first connector 41 can be an integral structure with the housing 20, and the second connector 42 can be an integral structure with the door 30. In particular, when the slide rail adopts the form of a groove, the surface of the door 30 is recessed to directly form the slide rail, and the sliding shaft is embedded in the slide rail. In this case, the door 30 at the location of the slide rail can be understood as the second connector 42.

[0055] 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 spaced apart along a first direction Z1 and both extend along a second direction Z2. When the door 30 is closed in the opening 22, the inner edge 31 is closer to the housing 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, which extends along the first direction Z1. When the door 30 is closed in the opening 22, the side edge 33 is perpendicular to the plane 221 where the opening 22 is located.

[0056] 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 spaced apart along a first direction Z1 and both extend along a third direction Z3. When the door 30 is closed at the opening 22, the first inner edge 34 is closer to the housing 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 side of the door 30 away from the pivot side 23 also has a second inner edge 36. The second inner edge 36 extends along a third direction Z3. When the door 30 is closed at 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 typically holds the side of the door 30 away from the pivot side 23 to open the door 30.

[0058] In this configuration, the first direction Z1, the second direction Z2, and the third direction Z3 are all perpendicular to each other. When the housing is correctly positioned, the first direction Z1 and the second direction Z2 are both horizontal, and the third direction Z3 is vertical. The pivot side 23 and the target side 24 are positioned opposite each other along the second direction Z2. Figure 2 The third direction Z3 is perpendicular to the plane of the paper shown in the figure, therefore the third direction Z3 is in Figure 2 The middle is represented as a point, and similarly, the first inner edge 34, the outer edge 35, and the second inner edge 36 are represented as points. Figure 2 It is presented as a point.

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

[0060] It should be noted that the enclosure device in this application embodiment can be designed with a single door, double doors, or even more doors 30. The enclosure device provides an independent accommodating space 21 for each door 30, that is, there is a one-to-one correspondence between the door 30 and the accommodating space 21, and the door 30 is used to block its corresponding accommodating space 21.

[0061] Linear guide rail mating

[0062] Please see Figure 2 and Figure 3 , Figure 3 This is a schematic diagram of the structure of the first embodiment of the slide shaft and slide rail of this application.

[0063] In one embodiment, the first connector 41 is provided with at least a slide shaft 411 and a slide shaft 412, and the second connector 42 is provided with at least 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.

[0064] Both slide rails 421 and 422 extend in a straight line. When the door 30 is blocked at the opening 22, slide rail 421 is perpendicular to the plane 221 where the opening 22 is located, and slide rail 422 is inclined relative to the plane 221 where the opening 22 is located, so that when the door 30 opens relative to the box 20 from the state of blocking the opening 22, the door 30 moves toward the target side 24 of the box 20.

[0065] Specifically, the second connector 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 30 is blocked in 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 in a straight line along the first reference line 62, and the slide rail 422 extends in a straight line along the second reference line 63. During the process of the door 30 opening relative to the box 20 from the state of self-sealing 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 20.

[0067] In the manner described above, as the door 30 opens relative to the housing 20 in a self-sealing state relative to the opening 22 under the action of the hinge assembly 40, the door 30 moves towards the target side 24 of the housing 20. This reduces the extent to which the door 30 extends beyond the outer wall 25 of the housing 20, thereby reducing the risk of the door 30 interfering with or colliding with external structures during rotation. In other words, this embodiment allows for a reduction in the gap between the housing device and the external structure located beside it, achieving a micro-gap or even a seamless finish, which is beneficial for the housing device to be installed using an embedded method.

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

[0069] In this embodiment, slide rails 421 and 422 have an intersection point. When the door 30 blocks the opening 22, slide shafts 411 and 412 are both far away from the opening 22 relative to the intersection point, and the line connecting slide shafts 411 and 412 is perpendicular to slide rail 422.

[0070] Specifically, when the door 30 blocks the opening 22, the door 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. Furthermore, the central axis 414 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 line connecting the intersection of the central axis 415 of the sliding shaft 412 and the second reference line 63 with the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63, that is, the line connecting the starting point of the sliding shaft 412 and the intersection 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 slide shaft 411 and the central axis 415 of slide shaft 412 are both perpendicular to the paper shown in the accompanying drawings of this application. Therefore, the central axis 414 of slide shaft 411 and the central axis 415 of slide shaft 412 are both presented as points in the accompanying drawings of this application.

[0072] In the above manner, as the door 30 opens relative to the housing 20 from its self-sealing state at the opening 22 under the action of the hinge assembly 40, the door 30 can move along a set trajectory. Specifically, as... Figure 4 and Figure 5 As shown, the outer edge 35 of the door body 30 can move along trajectory A1, the first inner edge 34 can move along trajectory A2, the second inner edge 36 can move along trajectory A3, and the third inner edge 51 of the door seal 50 can move along trajectory A4.

[0073] When the enclosure device is installed using an embedded method, the industry generally requires that the distance between the enclosure device and the external structure located beside it be less than or equal to 4mm, and the maximum opening angle of the door 30 need to be greater than or equal to 90°. In this embodiment, the door 30 of the enclosure device moves according to a set trajectory, which can ensure that the outer edge 35 of the door 30 exceeds the outer wall 25 of the enclosure 20 by a maximum distance g. max Less than or equal to 4mm, and able to guarantee the maximum opening angle α of the door body 30. max Greater than or equal to 90°, specifically the maximum door opening angle 'a' max It can reach 150°, thus meeting the requirements.

[0074] Furthermore, when the door 30 blocks the opening 22, the slide rail 422 extends in the direction toward the pivot side 23 and away from the housing 20, and the slide 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 slide shaft 412 is located on the side of the first reference line 62 away from the target side 24, such as... Figure 3 As shown. Alternatively, when the door 30 is blocked at the opening 22, the slide rail 422 extends in the direction towards the target side 24 and away from the housing 20, and the slide shaft 412 is located on the side of the first reference line 62 facing the target side 24, that is, the starting point of the slide shaft 412 is located on the side of the first reference line 62 facing the target side 24. In this way, the door 30 can move along a set trajectory when it opens relative to the housing 20 from the state of blocking the opening 22 under the action of the hinge assembly 40.

[0075] Please refer to the following: Figure 6 , Figure 6 This is a structural schematic diagram of the second embodiment of the slide shaft and slide rail of this application.

[0076] In one embodiment, the first connector 41 is further provided with a sliding shaft 413, and the second connector 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 in a straight line, and when the door 30 blocks the opening 22, the sliding rail 423 is inclined relative to the plane 221 where the opening 22 is located and the sliding rail 422.

[0077] Specifically, the second connector 42 also defines a third reference line 64, which is coplanar with the reference circle 61, and intersects the first reference line 62 and the second reference line 63 at the center O of the reference circle 61.

[0078] It should be noted that the central axis 416 of the slide shaft 413 is perpendicular to the plane of the paper shown in the accompanying drawings of this application. Therefore, the central axis 416 of the slide shaft 413 is presented as a point in the accompanying drawings of this application.

[0079] In this way, at any given time, at least two of the movement directions of slide shaft 411, slide shaft 412, and slide shaft 413 are different, which can avoid the problem of unstable movement of door body 30 caused by slide shaft 411, slide shaft 412, and slide shaft 413 having the same movement direction at a certain time, and is conducive to ensuring the stability of door body 30 movement.

[0080] In this embodiment, slide rails 421, 422, and 423 intersect. When the door 30 blocks the opening 22, the sliding shaft 413 moves away from the opening 22 relative to the intersection point, and the line connecting the sliding shafts 411 and 413 is perpendicular to the slide rail 423.

[0081] Specifically, when the door 30 is blocked at the opening 22, the minimum distance from the central axis 416 of the sliding 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. Furthermore, the line connecting the intersection of the central axis 416 of the sliding shaft 413 and the third reference line 64 with the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the third reference line 64. In other words, the line connecting the starting point of the sliding shaft 413 with the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the third reference line 64. Thus, as the door 30 opens relative to the housing 20 from its blocked state under the action of the hinge assembly 40, the door 30 can move along a set trajectory.

[0082] Furthermore, when the door 30 blocks the opening 22, the slide rail 423 extends in the direction toward the pivot side 23 and away from the housing 20, and the slide 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 slide shaft 413 is located on the side of the first reference line 62 away from the target side 24, such as... Figure 3As shown. Alternatively, when the door 30 is blocked at the opening 22, the slide rail 423 extends in the direction towards the target side 24 and away from the housing 20, and the slide shaft 413 is located on the side of the first reference line 62 facing 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 facing the target side 24. In this way, the door 30 can move along a set trajectory when it opens relative to the housing 20 from the state of blocking the opening 22 under the action of the hinge assembly 40.

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

[0084] Of course, in other embodiments of this application, when the door 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 refer to the following: Figure 7 , Figure 7 This is a structural schematic diagram of the third embodiment of the slide shaft and slide rail of this application.

[0086] In an alternative embodiment, the hinge assembly 40 may consist only of a sliding shaft 412 and a sliding rail 422, or a sliding shaft 413 and a sliding rail 423. During the opening of the door 30 relative to the housing 20 from its sealed state 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, thus guiding the door 30 to move along a predetermined trajectory.

[0087] Vertical linear guide rail and elliptical guide rail mating

[0088] Please see Figure 2 , Figure 8 and Figure 9 , Figure 8 This is a structural schematic diagram of the fourth embodiment of the slide shaft and slide rail of this application. Figure 9 This is a structural schematic diagram of the fifth embodiment of the slide shaft and slide rail of this application. In this application, the width of the slide shaft and slide rail is omitted in some of the accompanying drawings; the slide shaft is represented by its central axis, and the slide rail is represented by its center line.

[0089] In one embodiment, the first connector 41 is provided with at least a slide shaft 411 and a slide shaft 412, and the second connector 42 is provided with at least 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.

[0090] The slide rail 421 extends in a straight line, and the slide rail 422 extends along an ellipse. When the door 30 is blocked at 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 20 is away from the pivot side 23 relative to the slide rail 421, so that when the door 30 opens relative to the box 20 from the state of blocking the opening 22, the door 30 moves toward the target side 24 of the box 20.

[0091] 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. When the door 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 reference ellipse 65 away from the housing 20 is closer to the target side 24 relative to the first reference line 62.

[0092] The slide rail 421 extends in a straight line along the first reference line 62, and the slide rail 422 extends along the reference ellipse 65. During the process of the door 30 opening relative to the box 20 from the state of self-sealing 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 20.

[0093] In the manner described above, as the door 30 opens relative to the housing 20 in a self-sealing state relative to the opening 22 under the action of the hinge assembly 40, the door 30 moves towards the target side 24 of the housing 20. This reduces the extent to which the door 30 extends beyond the outer wall 25 of the housing 20, thereby reducing the risk of the door 30 interfering with or colliding with external structures during rotation. In other words, this embodiment allows for a reduction in the gap between the housing device and the external structure located beside it, achieving a micro-gap or even a seamless finish, which is beneficial for the housing device to be installed using an embedded method.

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

[0095] In this embodiment, the slide rail 421 passes through the center of the aforementioned ellipse. When the door 30 blocks the opening 22, both the slide shafts 411 and 412 are far from the opening 22 relative to the center of the ellipse, and the slide rail 422 extends in the direction toward the pivot side 23 and in the direction close to the housing 20.

[0096] Specifically, the second connector 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 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 of this circle. When the door 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.

[0097] For any point (x, y) in the coordinate system of the reference ellipse 65, the following relationship is satisfied:

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

[0099] Where 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 angle between the first reference line 62 and the second reference line 63.

[0100] When the door 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 to the plane 221 where the opening 22 is located. Furthermore, the central axis of the sliding shaft 411 is located at the intersection of the first reference line 62 and the reference circle 61, meaning 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, meaning 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, as the door 30 opens relative to the housing 20 in the state of self-blocking opening 22 under the action of hinge assembly 40, the door 30 can move according to the set trajectory.

[0102] In an exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 422 bends towards the housing 20. Specifically, the second connector 42 further defines a reference point 66, which is located on the second reference line 63. The line connecting the intersection of the reference point 66, 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 412 is farther from the center O of the reference circle 61 relative to the reference point 66, and when the door 30 blocks the opening 22, the slide rail 422 is on the side of the second reference line 63 facing the target side 24, such as... Figure 2 and Figure 8 As shown.

[0103] In another exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 422 bends away from the housing 20. Specifically, the starting point of the slide shaft 412 is close to the center O of the reference circle 61 relative to the reference point 66, and when the door 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, such as... Figure 2 and Figure 9 As shown.

[0104] Please see Figure 2 , Figure 10 and Figure 11 , Figure 10 This is a structural schematic diagram of the sixth embodiment of the slide shaft and slide rail of this application. Figure 11 This is a structural schematic diagram of the seventh embodiment of the slide shaft and slide rail of this application.

[0105] In one embodiment, the first connector 41 is provided with at least a slide shaft 411 and a slide shaft 412, and the second connector 42 is provided with at least 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.

[0106] The slide rail 421 extends in a straight line, and the slide rail 422 extends along an ellipse. When the door 30 is blocked at 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 20 is closer to the pivot side 23 relative to the slide rail 421, so that when the door 30 opens relative to the box 20 from the state of blocking the opening 22, the door 30 moves toward the target side 24 of the box 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. When the door 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 reference ellipse 65 away from the housing 20 is away from the target side 24 relative to the first reference line 62.

[0108] The slide rail 421 extends in a straight line along the first reference line 62, and the slide rail 422 extends along the reference ellipse 65. During the process of the door 30 opening relative to the box 20 from the state of self-sealing 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 20.

[0109] In the manner described above, as the door 30 opens relative to the housing 20 in a self-sealing state relative to the opening 22 under the action of the hinge assembly 40, the door 30 moves towards the target side 24 of the housing 20. This reduces the extent to which the door 30 extends beyond the outer wall 25 of the housing 20, thereby reducing the risk of the door 30 interfering with or colliding with external structures during rotation. In other words, this embodiment allows for a reduction in the gap between the housing device and the external structure located beside it, achieving a micro-gap or even a seamless finish, which is beneficial for the housing device to be installed using an embedded method.

[0110] In this embodiment, the slide rail 421 passes through the center of the aforementioned ellipse. When the door 30 blocks the opening 22, both the slide shafts 411 and 412 are away from the opening 22 relative to the center of the ellipse, and the slide rail 422 bends toward the pivot side 23 and away from the housing 20.

[0111] Specifically, the second connector 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 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 of this circle. When the door 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] For any point (x, y) in the coordinate system of the reference ellipse 65, the following relationship is satisfied:

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

[0114] Where 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 angle between the first reference line 62 and the second reference line 63.

[0115] When the door 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 to the plane 221 where the opening 22 is located. Furthermore, the central axis of the sliding shaft 411 is located at the intersection of the first reference line 62 and the reference circle 61, meaning 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, meaning 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, as the door 30 opens relative to the housing 20 in the state of self-blocking opening 22 under the action of hinge assembly 40, the door 30 can move according to the set trajectory.

[0117] In an exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 422 is located on the side away from the housing 20 from the line connecting the slide shaft 412 and the center of the aforementioned ellipse. Specifically, the second connector 42 also defines a reference point 66, which is located on the second reference line 63. The line connecting the intersection of the reference point 66, 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 412 is farther from the center O of the reference circle 61 relative to the reference point 66, and when the door 30 blocks the opening 22, the slide rail 422 is located on the side of the second reference line 63 facing the target side 24, such as... Figure 2 and Figure 10 As shown.

[0118] In another exemplary embodiment, when the door 30 blocks 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 aforementioned ellipse toward the housing 20. Specifically, the starting point of the slide shaft 412 is close to the center O of the reference circle 61 relative to the reference point 66, and when the door 30 blocks the opening 22, the slide rail 422 is located on the side of the second reference line 63 away from the target side 24, such as... Figure 2 and Figure 11 As shown.

[0119] Inclined linear guide rail and elliptical guide rail mating

[0120] Please see Figure 2 , Figure 12 and Figure 13 , Figure 12 This is a structural schematic diagram of the eighth embodiment of the slide shaft and slide rail of this application. Figure 13 This is a structural schematic diagram of the ninth embodiment of the slide shaft and slide rail of this application.

[0121] In one embodiment, the first connector 41 is provided with at least a slide shaft 411 and a slide shaft 412, and the second connector 42 is provided with at least 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.

[0122] The slide rail 421 extends in a straight line, and the slide rail 422 extends along an ellipse. When the door 30 is blocked at the opening 22, the slide rail 421 is inclined relative to the plane 221 where the opening 22 is located. The part of the slide rail 422 away from the box 20 is away from the pivot side 23 relative to the slide rail 421, so that when the door 30 opens relative to the box 20 from the state of blocking the opening 22, the door 30 moves toward the target side 24 of the box 20.

[0123] Specifically, the second connector 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. When the door 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 reference ellipse 65 away from the housing 20 is closer to the target side 24 relative to the first reference line 62.

[0124] The slide rail 421 extends in a straight line along the second reference line 63, and the slide rail 422 extends along the reference ellipse 65. During the process of the door 30 opening relative to the box 20 from the state of self-sealing 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 20.

[0125] In the manner described above, as the door 30 opens relative to the housing 20 in a self-sealing state relative to the opening 22 under the action of the hinge assembly 40, the door 30 moves towards the target side 24 of the housing 20.

[0126] In this embodiment, the slide rail 421 passes through the center of the aforementioned ellipse. When the door 30 blocks the opening 22, both the slide shafts 411 and 412 are far from the opening 22 relative to the center of the ellipse, and the slide rail 422 extends in the direction toward the pivot side 23 and in the direction close to the housing 20.

[0127] Specifically, the second connector 42 also 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 of this circle. When the door 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.

[0128] For any point (x, y) in the coordinate system of the reference ellipse 65, the following relationship is satisfied:

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

[0130] Where 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 angle between the first reference line 62 and the third reference line 64.

[0131] When the door 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 to the plane 221 where the opening 22 is located. Furthermore, the line connecting the intersection of the central axis of the sliding shaft 411 and the second reference line 63 with the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63; that is, the line connecting the starting point of the sliding shaft 411 with 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 sliding shaft 412 is located at the intersection 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 of the reference ellipse 65 and the third reference line 64.

[0132] In the above manner, as the door 30 opens relative to the housing 20 in the state of self-blocking opening 22 under the action of hinge assembly 40, the door 30 can move according to the set trajectory.

[0133] In an exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 422 bends towards the housing 20. Specifically, the second connector 42 further defines a reference point 66, which is located on a third reference line 64. The line connecting the intersection of the reference point 66, 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 farther from the center O of the reference circle 61 relative to the reference point 66, and when the door 30 blocks the opening 22, the slide rail 422 is on the side of the third reference line 64 facing the target side 24, such as... Figure 2 and Figure 12 As shown.

[0134] In another exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 422 bends away from the housing 20. Specifically, the starting point of the slide shaft 412 is close to the center O of the reference circle 61 relative to the reference point 66, and when the door 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, such as... Figure 2 and Figure 13 As shown.

[0135] In this embodiment, when the door 30 blocks the opening 22, the slide rail 421 extends in the direction toward the pivot side 23 and away from the housing 20, and the slide shaft 411 is located on the side of the first reference line 62 away from 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 away from the target side 24, such as... Figure 12 and Figure 13 As shown. Alternatively, when the door 30 is blocked at the opening 22, the slide rail 421 extends in the direction towards the target side 24 and away from the housing 20, and the slide shaft 411 is located on the side of the first reference line 62 facing 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 facing the target side 24. In this way, the door 30 can move along a set trajectory when it opens relative to the housing 20 from the state of blocking the opening 22 under the action of the hinge assembly 40.

[0136] Please see Figure 2 , Figure 14 and Figure 15 , Figure 14 This is a structural schematic diagram of the tenth embodiment of the slide shaft and slide rail of this application. Figure 15 This is a structural schematic diagram of the eleventh embodiment of the slide shaft and slide rail of this application.

[0137] In one embodiment, the first connector 41 is provided with at least a slide shaft 411 and a slide shaft 412, and the second connector 42 is provided with at least 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.

[0138] The slide rail 421 extends in a straight line, and the slide rail 422 extends along an ellipse. When the door 30 is blocked at the opening 22, the slide rail 421 is inclined relative to the plane 221 where the opening 22 is located. The part of the slide rail 422 away from the box 20 is closer to the pivot side 23 relative to the slide rail 421, so that when the door 30 opens relative to the box 20 from the state of blocking the opening 22, the door 30 moves toward the target side 24 of the box 20.

[0139] Specifically, the second connector 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. When the door 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 reference ellipse 65 away from the housing 20 is away from the target side 24 relative to the first reference line 62.

[0140] The slide rail 421 extends in a straight line along the second reference line 63, and the slide rail 422 extends along the reference ellipse 65. During the process of the door 30 opening relative to the box 20 from the state of self-sealing 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 20.

[0141] In the manner described above, as the door 30 opens relative to the housing 20 in a self-sealing state relative to the opening 22 under the action of the hinge assembly 40, the door 30 moves towards the target side 24 of the housing 20. This reduces the extent to which the door 30 extends beyond the outer wall 25 of the housing 20, thereby reducing the risk of the door 30 interfering with or colliding with external structures during rotation. In other words, this embodiment allows for a reduction in the gap between the housing device and the external structure located beside it, achieving a micro-gap or even a seamless finish, which is beneficial for the housing device to be installed using an embedded method.

[0142] In this embodiment, the slide rail 421 passes through the center of the aforementioned ellipse. When the door 30 blocks the opening 22, both the slide shafts 411 and 412 are away from the opening 22 relative to the center of the ellipse, and the slide rail 422 bends toward the pivot side 23 and away from the housing 20.

[0143] Specifically, the second connector 42 also 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 of this circle. When the door 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.

[0144] For any point (x, y) in the coordinate system of the reference ellipse 65, the following relationship is satisfied:

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

[0146] Where 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 angle between the first reference line 62 and the third reference line 64.

[0147] When the door 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 to the plane 221 where the opening 22 is located. Furthermore, the line connecting the intersection of the central axis of the sliding shaft 411 and the second reference line 63 with the intersection of the first reference line 62 and the reference circle 61 is perpendicular to the second reference line 63; that is, the line connecting the starting point of the sliding shaft 411 with 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 sliding shaft 412 is located at the intersection 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 of the reference ellipse 65 and the third reference line 64.

[0148] In the above manner, as the door 30 opens relative to the housing 20 in the state of self-blocking opening 22 under the action of hinge assembly 40, the door 30 can move according to the set trajectory.

[0149] In an exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 422 is located on the side away from the housing 20 from the line connecting the slide shaft 412 and the center of the aforementioned ellipse. Specifically, the second connector 42 also defines a reference point 66, which is located on the third reference line 64. The line connecting the intersection of the reference point 66, 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 far from the center O of the reference circle 61 relative to the reference point 66, and when the door 30 blocks the opening 22, the slide rail 422 is located on the side of the third reference line 64 facing the target side 24, such as... Figure 2 and Figure 14 As shown.

[0150] In another exemplary embodiment, when the door 30 blocks 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 aforementioned ellipse toward the housing 20. Specifically, the starting point of the slide shaft 412 is close to the center O of the reference circle 61 relative to the reference point 66, and when the door 30 blocks the opening 22, the slide rail 422 is located on the side of the third reference line 64 away from the target side 24, such as... Figure 2 and Figure 15 As shown.

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

[0152] Elliptical slide rail mating

[0153] Please see Figure 2 , Figure 16 and Figure 17 , Figure 16 This is a structural schematic diagram of the twelfth embodiment of the slide shaft and slide rail of this application. Figure 17 This is a structural schematic diagram of the thirteenth embodiment of the slide shaft and slide rail of this application.

[0154] In one embodiment, the first connector 41 is provided with at least a slide shaft 411 and a slide shaft 412, and the second connector 42 is provided with at least 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, and the slide rail 422 extends along the second reference ellipse 652. When the door 30 is blocked at the opening 22, the portion of the slide rail 421 away from the housing 20 is away from the pivot side 23, and the portion of the slide rail 422 away from the housing 20 is close to the pivot side 23, so that the door 30 moves toward the target side 24 of the housing 20 during the process of opening relative to the housing 20 from the state of blocking the opening 22.

[0156] It should be noted that "the portion of the slide rail away from the housing 20 that is away from the pivot side 23" means that the portion of the slide rail away from the housing 20 is away from the pivot side 23 relative to the portion of the slide rail near the housing 20. "The portion of the slide rail away from the housing 20 that is near the pivot side 23" means that the portion of the slide rail away from the housing 20 is near the pivot side 23 relative to the portion of the slide rail near the housing 20.

[0157] Specifically, the second connector 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 the first reference ellipse 651 and the second reference ellipse 652 coincide with the center O. When the door 30 blocks the opening 22, the first reference line 62 is perpendicular to the plane 221 where the opening 22 is located. The portion of the first reference ellipse 651 away from the housing 20 is closer to the target side 24 relative to the first reference line 62, and the portion of the second reference ellipse 652 away from the housing 20 is further away from the target side 24 relative to the first reference line 62.

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

[0159] In the manner described above, as the door 30 opens relative to the housing 20 in a self-sealing state relative to the opening 22 under the action of the hinge assembly 40, the door 30 moves towards the target side 24 of the housing 20. This reduces the extent to which the door 30 extends beyond the outer wall 25 of the housing 20, thereby reducing the risk of the door 30 interfering with or colliding with external structures during rotation. In other words, this embodiment allows for a reduction in the gap between the housing device and the external structure located beside it, achieving a micro-gap or even a seamless finish, which is beneficial for the housing device to be installed using an embedded method.

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

[0161] Specifically, the second connector 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 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 of this circle. When the door 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.

[0162] For any point (x, y) in the coordinate system of the first reference ellipse 651, the following relationship holds:

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

[0164] Where 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 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 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. Furthermore, 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, meaning 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, as the door 30 opens relative to the housing 20 in the state of self-blocking opening 22 under the action of hinge assembly 40, the door 30 can move according to the set trajectory.

[0167] In an exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 421 bends towards the housing 20. Specifically, the second connector 42 further defines a first reference point 661, which is located on the second reference line 63. The line connecting the first reference point 661, 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 farther from the center O of the reference circle 61 relative to the first reference point 661, and when the door 30 blocks the opening 22, the slide rail 421 is on the side of the second reference line 63 facing the target side 24, such as... Figure 2 and Figure 16 As shown.

[0168] In another exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 421 bends away from the housing 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 30 blocks the opening 22, the slide rail 421 is on the side of the second reference line 63 away from the target side 24, such as... Figure 2 and Figure 17 As 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 direction closer to the pivot side 23 and away from the box 20.

[0170] Specifically, the second connector 42 also defines a third reference line 64, which 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] For any point (x, y) in the coordinate system described above, the second reference ellipse 652 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] Where 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 30 relative to the box 20, and θ2 is the angle between the first reference line 62 and the third reference line 64.

[0174] When the door 30 blocks 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. Furthermore, 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, meaning 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, as the door 30 opens relative to the housing 20 in the state of self-blocking opening 22 under the action of hinge assembly 40, the door 30 can move according to the set trajectory.

[0176] In an exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 422 is located on the side away from the housing 20, opposite to the line connecting the slide shaft 412 and the center of the second reference ellipse 652. Specifically, the second connector 42 further defines a second reference point 662, which is located on the third reference line 64. The line connecting 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 farther from the center O of the reference circle 61 relative to the second reference point 662, and when the door 30 blocks the opening 22, the slide rail 422 is located on the side of the third reference line 64 facing the target side 24, such as... Figure 2 and Figure 16 As shown.

[0177] In another exemplary embodiment, when the door 30 blocks 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 facing the housing 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 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, such as... Figure 2 and Figure 17 As shown.

[0178] Please see Figure 2 , Figure 18 and Figure 19 , Figure 18 This is a structural schematic diagram of the fourteenth embodiment of the slide shaft and slide rail of this application. Figure 19 This is a structural schematic diagram of the fifteenth embodiment of the slide shaft and slide rail of this application.

[0179] In one embodiment, the first connector 41 is provided with at least a slide shaft 411 and a slide shaft 412, and the second connector 42 is provided with at least 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.

[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 30 is blocked at the opening 22, the portion of the slide rail 421 away from the housing 20 and the portion of the slide rail 422 away from the housing 20 are both away from the pivot side 23, so that when the door 30 opens relative to the housing 20 from the state of blocking the opening 22, the door 30 moves toward the target side 24 of the housing 20.

[0181] Specifically, the second connector 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. When the door 30 blocks the opening 22, the first reference line 62 is perpendicular to the plane 221 where the opening 22 is located. The portions of the first reference ellipse 651 and the second reference ellipse 652 that are away from the housing 20 are both closer to the target side 24 relative to the first reference line 62.

[0182] Slide rail 421 extends along the first reference ellipse 651, and slide rail 422 extends along the second reference ellipse 652. During the process of the door 30 opening relative to the box 20 from the state of self-sealing opening 22, slide shaft 411 moves along slide rail 421, and slide shaft 412 moves along slide rail 422, so that the door 30 moves toward the target side 24 of the box 20.

[0183] In the manner described above, as the door 30 opens relative to the housing 20 in a self-sealing state relative to the opening 22 under the action of the hinge assembly 40, the door 30 moves towards the target side 24 of the housing 20. This reduces the extent to which the door 30 extends beyond the outer wall 25 of the housing 20, thereby reducing the risk of the door 30 interfering with or colliding with external structures during rotation. In other words, this embodiment allows for a reduction in the gap between the housing device and the external structure located beside it, achieving a micro-gap or even a seamless finish, which is beneficial for the housing device to be installed using an embedded method.

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

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

[0186] Specifically, the second connector 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 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 of this circle. When the door 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] For any point (x, y) in the coordinate system of the first reference ellipse 651, the following relationship holds:

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

[0189] Where 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.

[0190] When the door 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 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. Furthermore, 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, meaning 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, as the door 30 opens relative to the housing 20 in the state of self-blocking opening 22 under the action of hinge assembly 40, the door 30 can move according to the set trajectory.

[0192] In an exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 421 bends towards the housing 20. Specifically, the second connector 42 further defines a first reference point 661, which is located on the second reference line 63. The line connecting the first reference point 661, 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 farther from the center O of the reference circle 61 relative to the first reference point 661, and when the door 30 blocks the opening 22, the slide rail 421 is on the side of the second reference line 63 facing the target side 24, such as... Figure 2 and Figure 18 As shown.

[0193] In another exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 421 bends away from the housing 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 30 blocks the opening 22, the slide rail 421 is on the side of the second reference line 63 away from the target side 24, such as... Figure 2 and Figure 19 As shown.

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

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

[0196] For any point (x, y) in the coordinate system described above, the second reference ellipse 652 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] Where 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 30 relative to the box 20, and θ2 is the angle between the first reference line 62 and the third reference line 64.

[0199] When the door 30 blocks 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. Furthermore, 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, meaning 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, as the door 30 opens relative to the housing 20 in the state of self-blocking opening 22 under the action of hinge assembly 40, the door 30 can move according to the set trajectory.

[0201] In an exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 422 bends towards the housing 20. Specifically, the second connector 42 further defines a second reference point 662, which is located on the third reference line 64. The line connecting 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 farther from the center O of the reference circle 61 relative to the second reference point 662, and when the door 30 blocks the opening 22, the slide rail 422 is on the side of the third reference line 64 facing the target side 24, such as... Figure 2 and Figure 18 As shown.

[0202] In another exemplary embodiment, when the door 30 blocks the opening 22, the slide rail 422 bends away from the housing 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 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, such as... Figure 2 and Figure 19 As shown.

[0203] Preferably, the starting point of the slide shaft 411 is farther away from the center O of the reference circle 61 relative to the first reference point 661, and the starting point of the slide shaft 412 is closer to the center O of the reference circle 61 relative to the second reference point 662, such as... Figure 18 As shown; or, the starting point of the slide shaft 411 is closer to the center O of the reference circle 61 relative to the first reference point 661, and the starting point of the slide shaft 412 is farther away from the center O of the reference circle 61 relative to the second reference point 662, as shown. Figure 19As shown. This results in a large angle between slide rails 421 and 422, which helps to ensure the stability of the movement of slide shafts 411 and 412, that is, to ensure the stable movement of the door body 30.

[0204] Elliptical slide rail inflection point

[0205] Please see Figure 20 , Figure 20 This is a schematic diagram of an embodiment of a slide rail extending along a reference ellipse.

[0206] In one embodiment, a slide rail extending along an ellipse (including the reference ellipse of the above embodiment) intersects the major axis of the ellipse at an inflection point 424. The slide rail has a target point 425 located on the side of the ellipse whose minor axis faces the inflection point 424. The angle α between the line connecting any target point 425 and the inflection point 424 and the major axis of the ellipse is greater than or equal to 10°.

[0207] By employing the above method, the excessive turning angle of the slide rail at the inflection point 424 can be avoided, reducing the risk of jamming when the slide shaft passes through the inflection point 424. This helps ensure smooth movement of the slide shaft, thus ensuring smooth opening and closing of the door. Furthermore, it reduces the overlap of the slide rail sections on both sides of the inflection point 424, which helps ensure the stability of the slide shaft's movement, thus ensuring stable door movement. It also facilitates the design and manufacture of the slide rail.

[0208] Slide rail angle

[0209] Please see Figure 21 , Figure 21 This is a schematic diagram of the structure of the sixteenth embodiment of the slide shaft and slide rail of this application.

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

[0211] Slide rail setting position

[0212] Please see Figure 2 and Figure 22 , Figure 22 This is a schematic diagram of a portion of the door body of this application.

[0213] The following section describes the location of the slide rails, assuming that door 30 is in the closed state.

[0214] In one embodiment, the minimum distance from the slide rail to the inner edge 31, outer edge 32, and side edge 33 is greater than or equal to 6 mm. In other words, the minimum distance from any of the slide rails, including slide rails 421, 422, and 423 in the above embodiments, to the inner edge 31, outer edge 32, and side edge 33 is greater than or equal to 6 mm. This provides sufficient space for the design and fabrication of the slide rails, facilitating the engineering design and fabrication of the hinge assembly 40.

[0215] In one embodiment, the different slide rails can be spaced apart from each other, meaning there is no intersection between them. Specifically, any two of the slide rails, including slide rails 421, 422, and 423 described in the above embodiment, are spaced apart from each other. This ensures that at any given time, different sliding shafts are in different slide rails, avoiding the instability caused by different sliding shafts being in the same slide rail. This embodiment helps ensure the stability of the door's movement.

[0216] It should be noted that the accompanying drawings of some embodiments of this application show the situation where different slide rails intersect. In this case, as long as the tangents of the slide rails at the positions of different slide shafts as described in the above embodiments have a sufficiently large included angle, the stability of the door movement can also be guaranteed.

[0217] Reference circle size and setting position

[0218] Please see Figure 2 , Figure 4 and Figure 23 , Figure 23 yes Figure 2 A schematic diagram of another part of the box-shaped device shown.

[0219] The following section describes the dimensions and location of the reference circle 61, assuming that the door 30 is in the closed state.

[0220] In one embodiment, as the position of the reference circle 61 moves from the side edge 33 toward the target side 24 of the housing 20, the maximum distance by which the outer edge 35 of the door 30 extends beyond the outer wall 25 of the housing 20 gradually decreases. Simultaneously, considering that the movement of the reference circle 61 toward the target side 24 of the housing 20 increases the amount of movement of the door 30 toward the target side 24 during opening.

[0221] In view of this, 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. Where R ≤ N ≤ 100mm. This ensures that during the opening process of the door 30 under the action of the hinge assembly 40, the maximum distance by which the outer edge 35 of the door 30 extends beyond the outer wall 25 of the housing 20 is controlled within the industry requirement of 4mm; simultaneously, it controls the amount of movement of the door 30 toward the target side 24 within a reasonable range, reducing the risk of interference or collision between the second inner edge 36 of the door 30 and other structures, and also reserving sufficient space for the user to open the door 30. Furthermore, 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, to facilitate the design and fabrication of the sliding shaft and slide rail on the hinge assembly 40.

[0222] In one embodiment, as the reference circle 61 moves from the outer edge 32 toward the inner edge 31, the outer edge 35 of the door 30 gradually moves toward the housing 20 during the opening of the door 30, increasing the risk of interference and collision between the outer edge 35 and the housing 20. When the center O of the reference circle 61 is close to the center of the opposite side edge 33, the outer edge 35 of the door 30 will interfere with and collide with the housing 20 during the opening of the door 30.

[0223] In view of this, in this embodiment, 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. Where R ≤ W ≤ (1 / 2)D. In this way, during the opening process of 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 housing 20 can be reduced. Furthermore, 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, to facilitate the design and fabrication of the sliding shaft and slide rail on the hinge assembly 40.

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

[0225] Therefore, in this embodiment, the distance from the center O of the reference circle 61 to the side edge 33 is N, where 15mm ≤ N ≤ 100mm. This reduces the risk of interference or collision between the first inner edge 34 of the door 30 and the housing 20 during the opening process under the action of the hinge assembly 40. Furthermore, the distance from the center O of the reference circle 61 to the side edge 33 is at least 15mm to facilitate the design and fabrication of the sliding shaft and slide rail on the hinge assembly 40.

[0226] 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 first inner edge 34 of the door 30 toward the box 20 during the opening of the door 30 does not change significantly. In this case, the selection of the position of the reference circle 61 has little effect on the amount of interference between the first inner edge 34 and the box 20, and more consideration is given to the design and manufacturing of the hinge assembly 40.

[0227] Therefore, 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. This allows for more flexible selection of the position of the reference circle 61, facilitating the design and manufacture of sliding shafts and rails, and enabling adaptation to application scenarios where the maximum opening angle of the door 30 reaches 150°.

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

[0229] Therefore, in this embodiment, the distance from the center O of the reference circle 61 to the side edge 33 is N, where 15mm ≤ N ≤ 100mm. This ensures that the maximum movement of the third inner edge 51 of the door seal 50 towards the housing 20 during the opening of the door 30 is less than or equal to 5mm, which helps improve the reliability and stability of the door seal 50. Furthermore, the distance from the center O of the reference circle 61 to the side edge 33 is at least 15mm to facilitate the design and fabrication of the sliding shaft and slide rail on the hinge assembly 40.

[0230] 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 third inner edge 51 of the door seal 50 toward the box 20 during the opening of 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 amount of pressure of the door seal 50, and more consideration is given to the design and manufacturing of the hinge assembly 40.

[0231] Therefore, 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. This allows for more flexible selection of the position of the reference circle 61, facilitating the design and manufacture of sliding shafts and rails, and enabling adaptation to application scenarios 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 35mm ≤ H ≤ 100mm. 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 300mm ≤ L ≤ 700mm. 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 0mm ≤ M ≤ 15mm.

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

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements.
