[0039] The following will describe the present invention in detail in conjunction with the embodiments shown in the accompanying drawings. Figure 1-Figure 8 The following are preferred embodiments of the present invention, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions. However, it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformation or substitution of functions, methods, or structures made by a person skilled in the art based on these embodiments shall fall within the protection scope of the present invention.

[0040] In the drawings of the present invention, for the convenience of illustration, some dimensions of structures or parts are exaggerated relative to other structures or parts, and therefore, are only used to illustrate the basic structure of the subject matter of the present invention.

[0041] Additionally, spatially relative terms such as "left," "right," "front," and "rear" used herein are for ease of description to describe the relationship of one element or feature relative to another element or feature as shown in the accompanying drawings. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the drawings. The device may be otherwise oriented (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein interpreted accordingly.

[0042] The terms first, second, etc. in the present invention are only used for descriptive purposes to distinguish these described objects from each other, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0043] Please refer to Figures 1 to 8 As shown, the utility model provides a storage device 100, including a box body 1, a door body 2 located at the opening side of the box body 1, and a hinge assembly 3 that rotatably connects the door body 2 to the box body 1.

[0044] In the following, the storage device 100 is specifically described as a refrigerator embedded in the cabinet 20, and only the cabinet 20 located at the pivot end of the door body 2 is shown. In actual installation, the refrigerator is completely embedded in the cabinet 20. Of course, it can be understood that it is not limited to this. The storage device 100 in this article is not necessarily a refrigerator, but can also be other household appliances such as a microwave oven and a wardrobe. At the same time, the storage device 100 in this article is not necessarily embedded in the cabinet 20, and can be used alone or embedded in other external environment parts such as a wall.

[0045] It is understandable that the hinge assembly 3 is provided at both the upper and lower ends of the box body 1 and the door body 2. Unless otherwise specified, the hinge assembly 3 mentioned below may refer to the hinge assembly 3 installed at the upper end or the hinge assembly 3 installed at the lower end.

[0046] Specifically, the door body 2 has a pivot end close to the hinge assembly 3 and rotated relative to the box body 1. Correspondingly, the door body 2 is specifically located at a pivot side wall 21 at the pivot end, a front wall 22 away from the box body 1 in the closed state, and a rear wall 23 close to the box body 1. The pivot side wall 21 connects the front wall 22 and the rear wall 23, and the front wall 22 and the pivot side wall 21 meet to form a door outer edge L. It should be noted that the front wall 22 and the rear wall 23 are almost parallel, and when the door body 2 is in a closed state of closing the opening side, the front wall 22 and the rear wall 23 are almost parallel to the plane where the opening side of the box body 1 is located. At the same time, the pivot side wall 21 is also almost parallel to the cabinet 20 located at the pivot end of the door body 2.

[0047] It is defined that when the door body 2 is in a closed state, the direction away from the pivoting side wall 21 is a first direction F1, the direction away from the box body 1 is a second direction F2, and the direction toward the box body 1 is a third direction F3.

[0048] Specifically, when the hinge assembly 3 is arranged on the right side of the box body 1 and the door body 2, the pivot end refers to the right end of the door body 2, the first direction F1 is the direction away from the cabinet 20 on the right side to the left, the second direction F2 is the direction away from the box body 1 to the front, and the third direction F3 is the direction close to the box body 1 to the rear; when the hinge assembly 3 is arranged on the left side of the box body 1 and the door body 2, the pivot end refers to the left end of the door body 2, the first direction F1 is the direction away from the cabinet 20 on the left side to the right, the second direction F2 is the direction away from the box body 1 to the front, and the third direction F3 is the direction close to the box body 1 to the rear.

[0049] Combination Figure 1-4 As shown, the hinge assembly 3 includes an axis structure 31 provided on one of the door body 2 and the box body 1, and a hinge groove 32 provided on the other of the door body 2 and the box body 1. The hinge groove 32 cooperates with the axis structure 31 to drive the door body 2 to move along a preset trajectory.

[0050] Below, the storage device 100 in the present invention is described by taking the shaft structure 31 being disposed on the box body 1 and the hinge groove 32 being disposed on the door body 2 as an example. However, this is not limiting, and it is known that in other embodiments, the shaft structure 31 may also be disposed on the door body 2, and the hinge groove 32 may be disposed on the box body 1.

[0051] Specifically, the hinge assembly 3 further includes a hinge plate 33 connected to the box body 1 , and the shaft structure 31 is disposed on the hinge plate 33 to be indirectly disposed on the box body 1 .

[0052] The shaft structure 31 includes a first shaft 311 connected to the hinge plate 33 and a second shaft 312 connected to the first shaft 311. The central axis of the first shaft 311 is offset from the central axis of the second shaft 312. During the rotation of the door body 2, the first shaft 311 and the second shaft 312 both move along the hinge groove 32. On the one hand, in the utility model, a double axis (a first axis 311 and a second axis 312) cooperates with a single groove (a hinge groove 32) for movement. When the shaft structure 31 moves along the hinge groove 32, the first axis 311 and the second axis 312 are in contact with the groove wall of the hinge groove 32 and can limit each other. Thus, the double axis and the single groove can change the movement trajectory of the door body 2 during the rotation of the door body 2 so that the door body 2 can adapt to different application scenarios. At the same time, it can improve the movement stability of the door body 2 during the rotation of the door body 2. On the other hand, in the shaft structure 31 of the utility model, only the first axis 311 is connected to the hinge plate 33, and the second axis 312 is connected to the first axis 311, which can simplify the installation between the shaft structure 31 and the hinge plate 33 and is conducive to the molding of the shaft structure 31.

[0053] It should be noted that, in the present invention, during the rotation of the door body 2, the rotation axis of the door body 2 relative to the rotation of the door body 2 is a virtual axis, not a physical axis.

[0054] Furthermore, the first shaft 311 includes a first end connected to the hinge plate 33 and a second end opposite to the first end; the shaft structure 31 also includes a connecting plate 313 connected to the second end, and the second shaft 312 is connected to the connecting plate 313. This is beneficial to the molding of the shaft structure 31.

[0055] In a specific embodiment, the first shaft 311 and the second shaft 312 are respectively arranged on opposite sides of the connecting plate 313 , which is beneficial to the forming of the shaft structure 31 and can further enhance the stability of the cooperation between the shaft structure 31 and the hinge groove 32 .

[0056] Specifically, the plane where the connecting plate 313 is located is parallel to the plane where the hinge plate 33 is located.

[0057] Furthermore, the door body 2 has a mounting end surface 24 for mounting the hinge assembly 3; the projection of the second axis 312 on the mounting end surface 24 partially overlaps with the projection of the first axis 311 on the mounting end surface 24. The distance between the first axis 311 and the second axis 312 along their radial directions can be reduced, thereby improving the smoothness of the movement of the shaft structure 31 along the hinge slot 32, improving the smoothness of opening and closing the door body 2, and enhancing the user experience.

[0058] In a specific embodiment, the central axis of the second axis 312 is parallel to the central axis of the first axis 311, and both are perpendicular to the plane where the mounting end surface 24 is located. The radius of the first axis 311 is d1, the radius of the second axis 312 is d2, and the distance d between the central axis of the second axis 312 and the central axis of the first axis 311 satisfies: 0<d≤d1+d2. That is, the central axis of the first axis 311 and the central axis of the second axis 312 are misaligned in the horizontal direction, and the projection of the second axis 312 on the mounting end surface 24 partially overlaps with the projection of the first axis 311 on the mounting end surface 24. The distance between the first axis 311 and the second axis 312 along their radial directions can be reduced, thereby improving the smoothness of the movement of the shaft structure 31 along the hinge slot 32, improving the smoothness of the opening and closing door body 2, and enhancing the user experience.

[0059] In this embodiment, the radius of the first shaft 311 is the same as the radius of the second shaft 312. Of course, this is not limiting, and in other embodiments, the radius of the first shaft 311 can also be set to be different from the radius of the second shaft 312. In this case, the width of the hinge slot 32 is adapted to be a stepped slot with different upper and lower widths to ensure that the first shaft 311 and the second shaft 312 are in contact with the slot wall of the hinge slot 32.

[0060] Further, the hinge plate 33 is detachably connected to the shaft structure 31. The hinge plate 33 has a mounting opening 331 for mounting the shaft structure 31. It is known that in the embodiment where the shaft structure 31 is disposed on the door body 2, the mounting opening 331 is disposed on the door body 2.

[0061] Furthermore, the installation opening 331 is provided with a first foolproof structure 3311, and the shaft structure 31 is provided with a second foolproof structure 3141 that matches the first foolproof structure 3311. When the shaft structure 31 is installed on the hinge plate 33, the cooperation between the first foolproof structure 3311 and the second foolproof structure 3141 facilitates installation, ensures that the installation angle of the shaft structure 31 is accurate, further improves the smoothness of the shaft structure 31 moving along the hinge slot 32, improves the smoothness of opening and closing the door body 2, and enhances the user experience.

[0062] In a specific embodiment, one of the first foolproof structure 3311 and the second foolproof structure 3141 is a foolproof bayonet, and the other is a foolproof convex block matched with the foolproof bayonet. When installing the shaft structure 31, the foolproof bayonet and the foolproof convex block are aligned and snapped into place, which is relatively simple. Of course, this is not limited to this. In other embodiments, the first foolproof structure 3311 and the second foolproof structure 3141 are matched planes and / or curved surfaces. When installing the shaft structure 31, the corresponding planes and / or curved surfaces of the first foolproof structure 3311 and the second foolproof structure 3141 are installed relatively.

[0063] Specifically, the shaft structure 31 further includes a mounting plate 314 connected to the first end, and the second fool-proof structure 3141 is disposed on the mounting plate 314, so as to avoid affecting the strength of the first shaft 311.

[0064] Furthermore, the shaft structure 31 is an integrated structure, that is, the first shaft 311 , the second shaft 312 , the mounting plate 314 , and the connecting plate 313 are integrally injection molded, which can improve the overall strength of the shaft structure 31 and simplify the installation of the shaft structure 31 .

[0065] Furthermore, combined with Figure 2 As shown, the plane where the front wall 22 and the pivoting side wall 21 are located forms a first target area located on the side of the front wall 22 away from the rear wall 23. In the process of the door body 2 rotating and opening from the closed state to the first opening angle, the door body 2 rotates in situ around the rotation axis, and the rotation axis is located in the first target area or on the boundary line of the first target area; correspondingly, the hinge slot 32 has an initial position and a first arc segment 321 connected to the initial position, and the center O1 of the first arc segment 321 is located in the target area or on the boundary line of the first target area, and the center O1 of the first arc segment 321 is located on the rotation axis. Combined with Figure 5-6As shown, when the door body 2 is in the closed state, the shaft structure 31 is located at the initial position. Specifically, in this embodiment, the second shaft 312 is located at the initial position. During the process of the door body 2 rotating from the closed state to the first opening angle, the first shaft 311 and the second shaft 312 both move along the first arc segment 321 to make the door body 2 rotate in situ around the rotation axis. It is known that at this time, because the rotation axis is located in the first target area or on the boundary line of the first target area, the door outer edge L has a movement component moving in the first direction F1, that is, when the door body 2 rotates from the closed state to open, the door outer edge L moves along the first direction F1 in the direction away from the cabinet 20 located at the pivot end, thereby avoiding interference with the cabinet 20.

[0066] It is known that the above-mentioned rotation axis refers to the axis of the virtual rotation axis corresponding to the process of the door body 2 rotating from the closed state to the first opening angle. In the embodiment in which the second axis 312 is located at the initial position when the door body 2 is in the closed state, when the door body 2 rotates to open to the first opening angle, the second axis 312 is located in the first arc segment 321, and the first axis 311 moves to the terminal position of the first arc segment 321 relative to the initial position.

[0067] Furthermore, combined with Figure 5-6 As shown, during the process of the door body 2 rotating from the closed state to the first opening angle, the door outer edge L simultaneously has a moving component moving toward the third direction F3. That is, while the door outer edge L moves away from the cabinet 20 at the pivot end along the first direction F1, it moves toward the box body 1 along the third direction F3, so that the center of gravity of the door body 2 is close to the box body 1 to avoid tipping.

[0068] Specifically, the distance between the rotation axis and the front wall 22 is 4mm-7mm; and / or, the distance between the rotation axis and the plane where the pivot side wall 21 is located is 10mm-14mm. That is, the distance between the center O1 of the first arc segment 321 and the front wall 22 is 4mm-7mm; and / or, the distance between the center O1 of the first arc segment 321 and the plane where the pivot side wall 21 is located is 10mm-14mm. When the door body 2 is rotated to open from the closed state, the outer edge L of the door moves along the first direction F1 away from the cabinet 20 at the pivot end to avoid interference with the cabinet 20. At the same time, the outer edge L of the door does not move too much along the first direction F1, so as to avoid the influence of the door body 2 on the opening side of the box body 1 after opening as much as possible, so as to realize more convenient access to objects.

[0069] Specifically, combined Figure 2 As shown, in the embodiment where the shaft structure 31 is provided on the box body 1 and the hinge slot 32 is provided on the door body 2, the first arc segment 321 extends obliquely from the initial position toward the pivoting side wall 21. The initial position is close to the front wall 22, which is conducive to the layout of the hinge slot 32 on the mounting end surface 24.

[0070] In a specific embodiment, the first opening angle is 60°. Of course, this is not limited to this.

[0071] Furthermore, combined with Figure 2 As shown, the hinge groove 32 also has at least one second arc segment 322 connected to one end of the first arc segment 321 away from the initial position. The first arc segment 321 and the second arc segment 322 have a smooth transition, which can improve the smoothness of the door body 2 during rotation.

[0072] Specifically, during the process of the door body 2 rotating to open, the shaft structure 31 moves along the direction of the first arc segment 321 toward the second arc segment 322. The radius of curvature of the first arc segment 321 is greater than the radius of curvature of the second arc segment 322, and the radius of curvature of the second arc segment 322 close to the first arc segment 321 of two adjacent second arc segments 322 is greater than the radius of curvature of the second arc segment 322 far from the first arc segment 321. That is, when the door body 2 continues to rotate to open from the first opening angle, the radius of curvature of the rotation of the door body 2 decreases, which can realize rapid opening of a large angle while reducing the rotation amount of the door body 2, thereby reducing the impact of the door body 2 on the opening side of the box body 1 when it is opened to the maximum opening angle, so as to more conveniently realize the taking and placing of objects.

[0073] Specifically, the front wall 22 , the rear wall 23 , and the pivoting side wall 21 together form a second target area; the center of the second arc segment 322 is located in the second target area, that is, the center of the second arc segment 322 is located on the mounting end surface 24 .

[0074] In a specific embodiment, the hinge groove 32 has a second arc segment 322 connected to one end of the first arc segment 321 away from the initial position. The number of times the shaft structure 31 switches between the arc segments during the rotation of the door body 2 can be reduced, thereby improving the smoothness of the rotation of the door body 2 and improving the user experience. Of course, this is not limited to this.

[0075] Specifically, in the embodiment where the hinge groove 32 has a second arc segment 322 connected to the end of the first arc segment 321 away from the initial position, the distance between the center O2 of the second arc segment 322 and the front wall 22 is 1mm-3mm; and / or, the distance between the center O2 of the second arc segment 322 and the plane where the pivoting side wall 21 is located is 18mm-22mm. Of course, it can be understood that this is not limited to this. In actual applications, the specific position of the center of the second arc segment 322 can be adjusted according to the trajectory requirements of the rear section of the door body 2 rotating to open.

[0076] Further, in an embodiment where the shaft structure 31 is provided on the box body 1, the hinge groove 32 is provided on the door body 2, and there is only one second arc segment 322, the second arc segment 322 extends obliquely from the junction with the first arc segment 321 toward the pivot side wall 21 and toward the door outer edge L. Figure 6-7 As shown, the second axis 312 and the first axis 311 are arranged along the arrangement direction of the first arc segment 321 and the second arc segment 322. In the process of the door body 2 continuing to rotate and open from the first opening angle, the first axis 311 moves along the second arc segment 322, and the second axis 312 moves along the first arc segment 321. When the door body 2 is rotated and opened to the maximum opening angle, the second axis 312 is located at the junction of the first arc segment 321 and the second arc segment 322, and the first axis 311 is located at the end of the second arc segment 322 away from the first arc segment 321. As shown in FIG. 3, in the process of the door body 2 rotating and opening from the first opening angle to the maximum opening angle, the door body 2 synchronously translates, and the direction of the translation includes the direction components of the first direction F1 and the second direction F2. That is, in the process of the door body 2 rotating and opening from the first opening angle to the maximum opening angle, the door body 2 will synchronously translate in the direction away from the cabinet 20 and the box body 1 located at the pivot end.

[0077] It can be seen that in the utility model, during the entire stage of the door body 2 rotating to open, the second axis 312 always moves along the first arc segment 321, and only the first axis 311 switches from the first arc segment 321 to the second arc segment 322, that is, one of the first axis and the second axis always moves along the first arc segment 321, and the other switches between the first arc segment 321 and the second arc segment 322, which can further improve the overall smoothness of the door body 2 during rotation.

[0078] In a specific implementation, the maximum opening angle is 90°, but of course, it is not limited thereto.

[0079] To summarize, the storage device 100 in the present invention, on the one hand, cooperates with the movement of double axes (the first axis 311 and the second axis 312) and the single groove (the hinge groove 32). During the movement of the axis structure 31 along the hinge groove 32, the first axis 311 and the second axis 312 are in contact with the groove wall of the hinge groove 32 and can limit each other. Therefore, the double axis and the single groove can change the movement trajectory of the door body 2 during the rotation of the door body 2 so that the door body 2 can adapt to different application scenarios. At the same time, it can improve the movement stability of the door body 2 during the rotation of the door body 2. On the other hand, in the axis structure 31 in the present invention, only the first axis 311 is connected to the door body 2 / box body 1, and the second axis 312 is connected to the first axis 311, which can simplify the installation between the axis structure 31 and the hinge plate 33 and is conducive to the molding of the axis structure 31.
