[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0029] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of the first embodiment of the box assembly of the present application. The box assembly 100 of this embodiment includes a box 11, a door 12 and a hinge assembly 13. The box 11 is used to form a receiving space with an opening, the door 12 is used to block the opening, and the hinge assembly 13 is arranged to pivotally connect the box 11 and the door 12 at the pivot side of the box 11, so that the door 12 can be opened or closed relative to the box 11 under the action of the hinge assembly 13.

[0031] There are many types of hinge assemblies for realizing relative rotation between the door body and the box body. The arrangement of the hinge assemblies determines the relative motion relationship between the door body and the box body. Figure 2 As shown, Figure 2 It is a schematic diagram of the movement relationship between the door body and the box body in the existing box body assembly. Among them, when the door body 92 is opened to a certain angle, the door body 92 squeezes the box body 91 and the door body 92 exceeds the side of the box body assembly 900. The side of the box body assembly 900 may be the side of the box body 91 or the side of the door body 92 when it is closed. Obviously, the hinge assembly 93 in the prior art cannot solve the technical problem of this application.

[0032] In this application, the motion trajectory of the edge on the door body is limited to alleviate the problem of the door body squeezing the box body and exceeding the side of the box body component. Based on the calculation principle of relative motion, the relative motion relationship between the door body and the box body can be determined according to the motion trajectory of the edge, and then the motion trajectory of the fixed point on the box body or the door body can be determined. According to the motion trajectory of the fixed point, the hinge component can be designed in reverse. Therefore, the hinge components that can realize the motion trajectory of the edge in this application are all within the protection scope of this application.

[0033] Please refer to Figure 3 and Figure 4 , Figure 3 yes Figure 1 The schematic diagram of the motion trajectory of the edge of the first embodiment of the box assembly is shown, Figure 4 yes Figure 1 The diagram shows the opening angle of the door relative to the box body and the movement trajectory of the edge in the first embodiment of the box body assembly.

[0034] The door body 12 of this embodiment has an inner edge 122 and an outer edge 121 on the pivot side, and when the door body 12 is in a closed state relative to the box body 11, the inner edge 122 is closer to the box body 11 than the outer edge 121. In this embodiment, a first reference plane X and a second reference plane Y are further defined, wherein the first reference plane X passes through the inner edge 122 in the closed state and is parallel to the plane where the opening is located; the second reference plane Y passes through the outer edge 121 in the closed state and is perpendicular to the plane where the opening is located.

[0035] When the door body 12 is opened from the closed state to the first opening angle relative to the box body 11 under the action of the hinge assembly 13, the inner edge 122 moves along the first inner edge trajectory A2B2 toward the second reference plane Y toward the opening side, and the outer edge 121 moves along the first outer edge trajectory A1B1 toward the first reference plane X. When the door body 12 moves, the first reference plane X and the second reference plane Y do not move with it, and are fixed reference planes. In the relationship of the pivotal connection between the door body 12 and the box body 11, during the opening process of the door body 12, the final movement direction of the inner edge 122 relative to the second reference plane Y and the final movement direction of the outer edge 121 relative to the first reference plane X must be the directions described above.

[0036] Furthermore, for the movement of the outer edge 121 and the inner edge 122 in their respective directions, the radius of curvature of the first outer edge trajectory A1B1 is not less than 5t, and the distance of the first outer edge trajectory A1B1 beyond the second reference plane Y away from the opening side is not greater than the first predetermined distance d1; the radius of curvature of the first inner edge trajectory A2B2 is not less than 100t, and the distance of the trajectory of the first inner edge A2B2 beyond the first reference plane X toward the opening side is not greater than the second predetermined distance d2, where t is the thickness of the door body.

[0037] In this embodiment, the curvature radius of the motion trajectory and the distance that the motion trajectory can exceed the reference plane are defined to ensure that the edge can move smoothly and within a predetermined range. Specifically, the minimum values ​​of the curvature radius of the first outer edge trajectory A1B1 and the curvature radius of the first inner edge trajectory A2B2 are defined, that is, when the curvature radius is selected to be the minimum value, it can be ensured that the door body 12 will not cause a large squeeze to the box body 11, and the door body 12 will not exceed the side of the box body assembly too much. In addition, when the curvature radius is selected to be infinite, the trajectory is a straight line, and corresponding to the case where both trajectories are straight lines, the door body 12 can be opened to a maximum of 90 degrees relative to the box body 11.

[0038] When limiting the radius of curvature, the thickness t of the door body is used as a reference standard, and the radius of curvature of the first outer edge track A1B1 is not less than 5t, and the radius of curvature of the first inner edge track A2B2 is not less than 100t. This is because the thickness t of the door body determines the degree of movement of the door body 12 relative to the box body 11 when it is opened. Obviously, the thicker the door body 12, the larger the radius of curvature of the movement track.

[0039] The relevant limitation of the first preset distance d1 determines the extent to which the outer edge 121 can extend beyond the side of the box assembly 100. In practical applications, the outer edge 121 can be allowed to extend beyond the side of the box assembly 100 to a certain extent. For example, for embedded use of the box assembly, there is a certain gap between the box 11 and the wall in which it is embedded, and the gap allows the outer edge 121 to extend beyond the side of the box assembly 100 to a certain extent.

[0040] Similarly, the relevant limitation of the second preset distance d2 determines the extent to which the inner edge 122 can squeeze the box body 11. In practical applications, the inner edge 122 can be allowed to squeeze the box body 11 to a certain extent. For example, if a deformable door seal is provided on the box body 11, the squeezing of the box body 11 to a certain extent by the inner edge 122 can be ignored.

[0041] In this embodiment, the first predetermined distance d1 can be set to 3 mm, and the second predetermined distance d2 can be set to 1.5 mm.

[0042] In general, in this embodiment, when the door body 12 is opened from the closed state to the first opening angle relative to the box body 11 under the action of the hinge assembly 13, the inner edge 122 moves along the first inner edge track A2B2, and the outer edge 121 moves along the first outer edge track A1B1. Among them, the curvature radius of the first inner edge track A2B2 and the first outer edge track A1B1, as well as the distance relationship between them and the first reference plane X and the second reference plane Y have certain characteristics. The door body 12 moves according to the track, thereby reducing or even avoiding the door body 12 from squeezing the box body 11, and the door body 12 extending beyond the side of the box body assembly 100.

[0043] Furthermore, in the present embodiment, the end point B2 of the first inner edge trajectory A2B2 is located on the first reference plane X, or the end point B2 is located on the side of the first reference plane X away from the opening and the distance to the first reference plane X is not greater than 0.058t; the end point B1 of the first outer edge trajectory A1B1 is located on the second reference plane Y, or the end point B1 is located on the side of the second reference plane Y toward the opening and the distance to the second reference plane Y is not greater than 0.135t.

[0044] That is, after the door body 12 is opened to the first opening angle, the inner edge 122 of the door body 12 will not squeeze the box body 11, and will not move too far away from the box body 11; the outer edge 121 will not exceed the side of the box assembly 100, and will not move too much toward the second reference plane Y toward the opening side. This ensures that the door body 12 will not have obvious displacement problems when it is opened, and the movement of the door body 12 is more stable.

[0045] In this embodiment, if the edge of the door body 12 moves along the first inner edge track A2B2 and the first outer edge track A1B1 until the door body 12 opens 90 degrees, the door body 12 will not be able to continue to open, and the maximum opening angle of the door body 12 generally needs to be greater than 90 degrees. Therefore, after the edge of the door body 12 moves along the first inner edge track A2B2 and the first outer edge track A1B1 and the door body 12 opens less than 90 degrees, other movement tracks are used so that it can be opened more than 90 degrees. When the door body 12 opens less than 90 degrees, the length of the first inner edge track A2B2 is greater than the length of the first outer edge track A1B1, and the ratio of the length of the first inner edge track A2B2 to the length of the first outer edge track A1B1 is 3.5 to 4.5.

[0046] As mentioned above, the door body 12 may move along another trajectory after opening to the first opening angle. In this embodiment, when the door body 12 is opened from the first opening angle to the second opening angle relative to the box body 11 under the action of the hinge assembly 13, the inner edge 122 moves along the second inner edge trajectory B2C2 toward the side of the second reference plane Y toward the opening and the side of the first reference plane X away from the opening, and the outer edge 121 moves toward the first reference plane X along the second outer edge trajectory B1C1.

[0047] The inner edge 122 starts to move toward the second reference plane Y toward the side of the opening, and the movement trajectory of the inner edge 122, the curvature radius of the second inner edge trajectory B2C2 gradually decreases, and the end point C2 of the second inner edge trajectory B2C2 is located on the side of the first reference plane X away from the opening, and the distance to the first reference plane is not less than 0.3t, so that the door body 12 has space to open a larger angle.

[0048] In this process, the second outer edge trajectory B1C1 is designed according to the first outer edge trajectory A1B1, and its curvature radius is not less than 5t. The distance of the second outer edge trajectory B1C1 beyond the second reference plane Y away from the outlet is not greater than the first preset distance d1.

[0049] According to the characteristics of the above trajectory, when the door body 12 is opened from the first opening angle to the second opening angle, the door body 12 will not squeeze the box body 11, nor will it exceed the side of the box body assembly too much.

[0050] The door body 12 can continue to open from the second opening angle to the third opening angle relative to the box body 11 under the action of the hinge assembly 13. During this process, the inner edge 122 moves along the third inner edge track C2D2 toward the side of the first reference plane X away from the opening, and the outer edge 121 moves along the third outer edge track C1D1 toward the side of the second reference plane Y toward the opening. The track of this movement direction also corresponds to a larger opening angle of the door body 12.

[0051] The third inner edge track C2D2 and the third outer edge track C1D1 are specifically concentrically arranged circular arcs, and the curvature radius of the third inner edge track C2D2 is 0.55t-0.67t, and the curvature radius of the third outer edge track C1D1 is 0.45t-0.55t.

[0052] After the edges of the door body 12 move along the first inner edge trajectory A2B2 and the first outer edge trajectory A1B1, in order to achieve a larger door opening angle, they can also move directly along the third inner edge trajectory C2D2 and the third outer edge trajectory C1D1, thereby solving the problem of squeezing the box body 11 and exceeding the side of the box body assembly.

[0053] However, after the hinge assembly 13 is designed based on the first track plus the third track, when the door body 12 is rotated through the hinge assembly 13, shaking may occur during the rotation process. In order to further optimize and solve the shaking problem, a second track is added between the first track and the third track to make the movement of the door body 12 more stable and smooth.

[0054] Furthermore, considering the design of the hinge assembly 13 , the ratio of the curvature radius of the third inner edge track C2D2 to the curvature radius of the third outer edge track C1D1 is 1.22, which can prevent interference problems in the structure corresponding to the third track on the hinge assembly 13 .

[0055] Specifically, with the three-segment trajectory design, the first opening angle corresponding to the first trajectory is 25 to 31 degrees, the second opening angle corresponding to the second trajectory is 57 to 60 degrees, and the third opening angle corresponding to the third trajectory is 122 to 132 degrees.

[0056] The length of the first inner edge track A2B2 is 0.465t, and the length of the first outer edge track A1B1 is 0.115t.

[0057] The length of the second outer edge track B1C1 is 0.2285t, and the second inner edge track B2C2 is set so that the movement distance of the outer edge 121 on the second outer edge track B1C1 and the rotation angle of the door body 12 relative to the box body satisfy the following formula:

[0058]

[0059] Among them, θ1 is the rotation angle, t1 is the movement distance, and θ is a preset angle of 100 degrees to 113 degrees.

[0060] The curvature radius of the third inner edge track C2D2 is 0.61t, and the curvature radius of the third outer edge track C1D1 is 0.5t. The center of the third inner edge track C2D2 and the third outer edge track C1D1 is located inside the door body 12, and the distance from the center to the first reference plane X is 0.6t, and the distance to the second reference plane Y is 0.5t.

[0061] During actual design, taking into account installation deformation and other issues, reference points may be selected for trajectory design, thereby reserving tolerances for the edges on the door body 12 to ensure that the door body 12 does not squeeze the box body 11 or extend beyond the side of the box body assembly 100 .

[0062] like Figure 5 , Figure 6 and Figure 7 As shown, Figure 5 yes Figure 1 The schematic diagram of the motion trajectory of the reference point in the first embodiment of the box assembly is shown, Figure 6 yes Figure 1 The schematic diagram of the selection range of the internal reference points in the first embodiment of the box assembly is shown, Figure 7 yes Figure 1 A schematic diagram of the selection range of internal and external reference points in the first embodiment of the box assembly is shown.

[0063] In this embodiment, an inner reference point R2 and an outer reference point R1 are set. The inner reference point R2 is set adjacent to the inner edge 122 , and the outer reference point R1 is set adjacent to the outer edge 121 .

[0064] Specifically, the vertical distance from the inner reference point R2 to the first reference plane X is not greater than 0.1t, and the vertical distance to the second reference plane Y is not greater than 0.1t, that is, the selection range of the inner reference point R2 is a rectangular area with the inner edge 122 as the center and a side length of 0.2t; similarly, the vertical distance from the outer reference point R1 to the second reference plane Y is not greater than 0.1t, and the vertical distance to the third reference plane Z is not greater than 0.1t, that is, the selection range of the outer reference point R1 is a rectangular area with the outer edge 121 as the center and a side length of 0.2t.

[0065] The inner reference point R2 may be selected on the inner edge 122 , and the outer reference point R1 may be selected on the outer edge 121 .

[0066] The trajectory design ideas of the inner reference point R2 and the outer reference point R1 are also based on the trajectory design ideas of the above inner edge 122 and the outer edge 121. When the door body 12 is opened from a closed state relative to the box body 11 to a first opening angle under the action of the hinge assembly 13, the inner reference point R2 moves along the first inner reference point trajectory E2F2 toward the second reference plane Y toward the opening side, and the outer reference point R1 moves along the first outer reference point trajectory E1F1 toward the first reference plane X.

[0067] Possible features of the first inner reference point trajectory E2F2 are similar to those of the first inner edge trajectory A2B2, and possible features of the first outer reference point trajectory E1F1 are similar to those of the first outer edge trajectory A1B1, and details are not repeated here.

[0068] For the convenience of design, in this embodiment, the first inner reference point trajectory E2F2 and the first outer reference point trajectory E1F1 are both straight lines. Based on the selected position of the inner reference point R2, the first inner reference point trajectory E2F2 can be along the first reference plane X or parallel to the first reference plane X; and based on the selected position of the outer reference point R1, the first outer reference point trajectory is along the second reference plane Y or parallel to the second reference plane Y.

[0069] Further, the length of the first inner reference point track E2F2 is greater than the length of the first outer reference point track E1F1, and the ratio of the length of the first inner reference point track E2F2 to the length of the first outer reference point track E1F1 is 3.5-4.5.

[0070] Similarly, corresponding to the inner edge 122 and the outer edge 121, the inner reference point R2 and the outer reference point R1 may have a second track and a third track. Among them, the second inner reference point track F2G2 may have similar characteristics to the second inner edge track B2C2, and the second outer reference point track F1G1 may have similar characteristics to the second outer edge track B1C1; the third inner reference point track G2H2 may have similar characteristics to the third inner edge track C2D2, and the third outer reference point track G1H1 may have similar characteristics to the third outer edge track C1D1.

[0071] When the door body 12 is opened from a first opening angle to a second opening angle relative to the box body 11 under the action of the hinge assembly 13, the inner reference point R2 moves along the second inner reference point trajectory F2G2 toward the side of the second reference plane Y toward the opening and the side of the first reference plane X away from the opening, and the outer reference point R1 moves along the second outer reference point trajectory F1G1 toward the first reference plane X.

[0072] For the convenience of design, the second outer reference point trajectory F1G1 is a straight line, arranged along the second reference plane Y, or arranged parallel to the second reference plane Y. The second inner reference point trajectory F2G2 is arranged so that the movement distance of the outer reference point on the second outer reference point trajectory and the rotation angle of the door body 12 satisfy the following formula:

[0073]

[0074] Among them, θ1 is the rotation angle, t1 is the movement distance, and θ is a preset angle of 100 degrees to 113 degrees.

[0075] Starting from the trajectory design of the edge of the door body 12 and based on the design principle of relative motion, a variety of hinge assembly structures can be designed. Figure 8-10 As shown, Figure 8 It is a structural schematic diagram of the second embodiment of the box assembly of the present application. Fig. 9 yes Figure 8 The schematic diagram of the hinge shaft structure of the hinge assembly in the second embodiment of the box assembly is shown in FIG. Fig.10 yes Figure 8 The diagram shows a schematic diagram of the hinge groove structure of the hinge assembly in the second embodiment of the box assembly.

[0076] Compared with the second embodiment Figure 1 The first embodiment shown only specifies the structure of the hinge assembly, so the reference numerals continue to use the reference numerals in the first embodiment. The design of the hinge assembly 13 in the box assembly 100 of this embodiment is to convert the motion trajectory of the edge of the door body 12 into the motion trajectory of two fixed points on the door body 12 or the box body 11, and then design the corresponding mechanical structure based on the motion trajectory of the two fixed points. The hinge assembly 13 includes a first guide mechanism 135 and a second guide mechanism 136, which respectively realize the motion trajectory of the two fixed points, that is, the cooperation of the two guide mechanisms can make the edge of the door body 12 move along a preset trajectory.

[0077] exist Figure 8-10 The middle guide mechanism is a slot-column matching structure. Obviously, the guide mechanism designed based on the trajectory can also be a connecting rod structure, a slot-column + connecting rod structure, etc.

[0078] The hinge assembly 13 in this embodiment is a double-shaft double-groove, and the double groove is set on the door body 12, and the double shaft is set on the box body 11. Similarly, in other embodiments, the double groove can also be set on the box body 11, and the double shaft can be set on the door body 12; or one shaft and one groove are set on the door body 12, and one shaft and one groove are also set on the corresponding box body 11; or as mentioned above, the shaft groove structure on the door body 12 and the box body 11 can be converted into a connecting rod structure, or a shaft + track sliding structure, etc.

[0079] Specifically, the hinge assembly 13 of this embodiment includes a first hinge shaft 131 and a second hinge shaft 132 disposed on the box body 11, and a first hinge groove 133 and a second hinge groove 134 disposed on the door body 12. The first hinge shaft 131 moves in the first hinge groove 133, and the two constitute a first guide mechanism 135; the second hinge shaft 132 moves in the second hinge groove 134, and the two constitute a second guide mechanism 136; thereby achieving the following Figure 3 The movement trajectory of the door edge shown in the figure solves the problem of the door 12 squeezing the box body 11 and the problem of the door 12 exceeding the side of the box body assembly 100.
