[0045] Please refer Figures 1 - 14 As shown, this application provides a storage device 100, including a box body 1, a door body 2 located on the opening side of the box body 1, and a hinge mechanism that movably connects the door body 2 to the box body 1. The box body 1 is used to provide an internal storage space so that the user can store items in the box body 1. The door body 2 is used to open or close the storage space from the opening side. When the door body 2 opens the storage space, it is convenient for the user to pick up and place items. When the door body 2 closes the storage space, the door body 2 and the box body 1 together form a closed storage space. The hinge mechanism is used to provide guidance for the movement of the door body 2, control the rotation opening angle of the door body 2, and the movement trajectory of the door body 2 during rotation.

[0046] The door body 2 has a connection end P movably connected to the box body 1. During the process of the door body 2 rotating to open / close, the door body 2 rotates around the connection end P to open / close the opening side.

[0047] It can be known that the connection end P refers to the end of the door body 2 close to the hinge mechanism.

[0048] In the following text, taking the storage device 100 as a refrigerator embedded in a cabinet as an example for specific elaboration, that is, taking the storage device 100 as an embedded refrigerator as an example for specific elaboration. Of course, it can be understood that this is not limited thereto. The storage device 100 in this application is not necessarily a refrigerator, and can also be other household appliances such as a microwave oven or a wardrobe. At the same time, the storage device 100 in this application is not necessarily embedded in the cabinet, and can be used alone, or can also be embedded in other external environmental components such as a wall.

[0049] CombinedFigures 1 to 4 As shown, the hinge mechanism includes a first hinge assembly 3 and a second hinge assembly 4 respectively disposed at opposite ends of the door body 2. In a specific embodiment, the first hinge assembly 3 is disposed at the upper end of the door body 2, and the second hinge assembly 4 is disposed at the lower end of the door body 2. The door body 2 is movably connected to the box body 1 through the first hinge assembly 3 and the second hinge assembly 4 together, and the movement track of the door body 2 is controlled.

[0050] Specifically, the door body 2 has an installation end face 21 for installing the hinge mechanism, including an upper installation end face at the upper end of the door body 2 and a lower installation end face at the lower end of the door body 2. The first hinge assembly 3 is installed at the end of the upper installation end face close to the connection end P, and the second hinge assembly 4 is installed at the end of the lower installation end face close to the connection end P. The door body 2 is driven to move around the connection end P along a preset track through the first hinge assembly 3 and the second hinge assembly 4.

[0051] The first hinge assembly 3 includes a first shaft body 31 and a first groove body 32 that cooperate with each other, and the second hinge assembly 4 includes a second shaft body 41 and a second groove body 42 that cooperate with each other. The central axes of the first shaft body 31 and the second shaft body 41 are not collinear. During the process of the door body 2 rotating and opening, the first shaft body 31 moves in the first groove body 32. At the same time, the second shaft body 41 moves in the second groove body 42 to provide guidance for the movement of the door body 2 and control the opening angle and movement track of the door body 2.

[0052] In the storage device 100 of the present application, by providing two single-axis and single-groove hinge assemblies (the first hinge assembly 3 and the second hinge assembly 4) together to provide guidance for the movement of the door body 2, the opening angle and movement track of the door body 2 can be controlled, and interference between the door body 2 and external environmental components during the process of the door body 2 rotating and opening can be avoided, so that the storage device 100 is suitable for an embedded use scenario; at the same time, the volume of each hinge assembly can be reduced.

[0053] Both the first hinge assembly 3 and the second hinge assembly 4 include a hinge plate 33 fixed to the box body 1 and a movable hinge member 34 fixed to the installation end face 21. Specifically, the first hinge assembly 3 includes a first hinge plate 33a and a first movable hinge member 34a, and the second hinge assembly 4 includes a second hinge plate 33b and a second movable hinge member 34b.

[0054] In a specific embodiment, the first shaft 31 is arranged on the first hinge plate 33a, the second shaft 41 is arranged on the second hinge plate 33b, the first slot 32 is arranged on the first movable hinge 34a, and the second slot 42 is arranged on the second movable hinge 34b. Of course, it is not limited to this. In other embodiments, the first shaft 31 and the second shaft 41 can also be arranged on the first movable hinge 34a and the second movable hinge 34b respectively, and the first slot 32 and the second slot 42 can be arranged on the first hinge plate 33a and the second hinge plate 33b respectively; or the first shaft 31 is arranged on the first hinge plate 33a, and the second shaft 41 is arranged on the second movable hinge 34b, or the first shaft 31 is arranged on the first movable hinge 34a, and the second shaft 41 is arranged on the second hinge plate 33b.

[0055] It is known that the movable hinge 34 can be set separately from the mounting end surface 21 , or can be set integrally with the mounting end surface 21 . In this case, the movable hinge 34 is a part of the mounting end surface 21 .

[0056] In some optional embodiments, the first slot body 32 and the second slot body 42 have different shapes, or the movement trajectory of the first shaft body 31 and the movement trajectory of the second shaft body 41 are different during the rotation opening of the door body 2. Therefore, during the rotation opening / closing of the door body 2, the two hinge assemblies can guide and restrict each other, so that the door body 2 can be rotated open / closed more smoothly, and at the same time, unnecessary shaking of the door body 2 can be avoided during the rotation process, thereby improving the stability of the movement of the door body 2.

[0057] In a specific embodiment, during the process of the door body 2 rotating to open, the first shaft body 31 moves unidirectionally along the first slot body 32; during the process of the first shaft body 31 moving unidirectionally along the first slot body 32, the second shaft body 41 has a reciprocating stage of reciprocating in the second slot body 42, at this time, the second slot body 42 is a short slot, and the first slot body 32 is a long slot. Of course, this is not limited to this.

[0058] In this embodiment, during the process of the door body 2 rotating and opening, the hinge mechanism is configured to drive the door body 2 to translate along a preset trajectory. That is, at a certain stage of the door body 2 rotating and opening, the door body 2 not only rotates, but also translates along a preset trajectory, thereby avoiding interference between the door body 2 and the cabinet.

[0059] Specifically, when the door body 2 is used to close the opening side, the direction from the center of the door body 2 toward the connection end P is the first direction F. 1 , and the first direction F 1The opposite direction is the second direction F 2 , the direction from the center of the door body 2 towards the opening side is the third direction F 3 、and the direction opposite to the third direction F 3 is the fourth direction F 4 .

[0060] It can be known that when the connection end P is the left end of the door body 2, the first direction F 1 is the outward direction from right to left, and the second direction F 2 is the inward direction from left to right; when the connection end P is the right end of the door body 2, the first direction F 1 is the outward direction from left to right, and the second direction F 2 is the inward direction from right to left. The third direction F 3 is the direction from front to back, and the fourth direction F 4 is the direction from back to front.

[0061] In some optional embodiments, during the process of the door body 2 rotating and opening, the preset trajectory sequentially includes a first translation stage of translating in the second direction F 2 , and a second translation stage of translating in the first direction F 1 . That is, while the door body 2 is rotating and opening, the door body 2 first translates inward in the second direction F 2 , that is, moves away from the cabinet located at the connection end P, so as to avoid interference between the door body 2 and the cabinet during the opening process. Then the door body 2 translates outward in the first direction F 1 to increase the opening degree of the opening side of the box body 1 to avoid the door body 2 hindering the pulling out of drawers, shelves, etc. inside the box body 1 and affecting the user's access to items.

[0062] In an optional embodiment, when the door body 2 is in the first translation stage, the door body 2 has a translation stage of translating simultaneously in the second direction F 2 and the third direction F 3 . That is, while the door body 2 is translating inward in the second direction F 2 , it moves backward in the third direction F 3 towards the box body 1, which can make the center of gravity of the door body 2 move backward, that is, make the center of gravity of the door body 2 closer to the box body 1, and can avoid the door body 2 from tipping over.

[0063] In a specific embodiment, when the door body 2 is in the first translation stage, while the door body 2 is translating inward in the second direction F 2 , it first moves backward in the third direction F 3 towards the box body 1, and then moves in the fourth direction F 4Move forward in the direction away from the box body 1. In the later stage of the first translation stage, the forward movement of the door body 2 can provide a greater backward movement margin for the subsequent translation stage. At the same time, it is also beneficial to improve the smoothness of the rotation and opening of the door body 2.

[0064] In an optional embodiment, when the door body 2 is in the second translation stage, the door body 2 moves outward along the first direction F 1 while moving backward along the third direction F 3 in the direction close to the box body 1. It can increase the opening degree of the opening side of the box body 1 to avoid the door body 2 hindering the pulling of drawers, shelves, etc. inside the box body 1, and at the same time, move the center of gravity of the door body 2 backward, that is, make the center of gravity of the door body 2 closer to the box body 1, and can avoid the door body 2 from tipping over.

[0065] In some optional embodiments, before the hinge mechanism drives the door body 2 to translate along a preset trajectory, the door body 2 rotates and opens in place. That is, in the initial stage of the rotation and opening of the door body 2 from the closed state of closing the opening side, the door body 2 first rotates in place to open the opening side. At this time, the door body 2 only rotates without generating translation in other directions, which can effectively avoid the abnormal opening of the door body 2 caused by the displacement of the door body 2 in a certain direction, such as the door body 2 with a flipping beam. After the door body 2 rotates in place and smoothly opens the door body 2, it enters the middle stage of the opening of the door body 2. At this time, the door body 2 enters the translation stage, that is, during the rotation of the door body 2, it synchronously translates along the above-mentioned preset trajectory to overcome the problems existing in the prior art of always rotating in place around a fixed axis, such as the easy interference between the door body 2 and external environmental components, the limited opening angle of the door body 2, and the limited opening degree of the opening side of the box body 1 resulting in difficult access to items. Of course, it is not limited to this.

[0066] In some optional embodiments, after the hinge mechanism drives the door body 2 to translate along a preset trajectory, the door body 2 rotates and opens in place. That is, in the final stage of the opening of the door body 2, the door body 2 continues to rotate and open in place, increasing the rotation amount of the door body 2, which is beneficial to the door body 2 opening a larger angle and facilitating the user to take and place items.

[0067] Specifically, in the initial and final stages of the opening of the door body 2, the door body 2 can be set to rotate and open in place around a virtual axis or around a physical axis.

[0068] The virtual axis refers to an axis that does not actually exist in the first hinge assembly 3 and the second hinge assembly 4, and the physical axis refers to the components actually included in the first hinge assembly 3 and the second hinge assembly 4, such as the first shaft body 31 and the second shaft body 41.

[0069] In a specific embodiment, in combination with Figures 4 to 13As shown, the first groove body 32 has an initial position A and a first arc groove section 321 communicating with the initial position A. The second groove body 42 has a starting position B 1 , when the door body 2 is in the closed state, the first shaft body 31 is located at the initial position A, and the second shaft body 41 is located at the starting position B 1 . The second shaft body 41 located at the starting position B 1 has a projection on the plane of the first hinge assembly 3 that coincides with the center of the first arc groove section 321. In the initial stage of the door body 2 rotating and opening from the closed state, as shown in Figures 4 to 7 , the second shaft body 41 remains at the starting position B 1 , the first shaft body 31 moves along the first arc groove section 321, and the door body 2 rotates and opens in place around the second shaft body 41 located at the starting position B 1 . When the first shaft body 31 moves to the end of the first arc groove section 321 away from the initial position A, the door body 2 rotates and opens to the first opening angle. At this time, in the initial stage of the door body 2 opening, the door body 2 rotates and opens in place around a solid shaft, that is, rotates and opens in place around the second shaft body 41

[0070] Specifically, the door body 2 includes a door lining that cooperates with the opening side, a door side wall 22 located at the connection end P, and a door panel 23 located at one end of the door side wall 22 away from the box body 1. The door lining and the door panel 23 are located at opposite ends of the connection end P

[0071] The first arc groove section 321 extends from the initial position A towards the door lining and towards the connection end P

[0072] In a specific embodiment, the first opening angle is 10°, of course, it is not limited thereto

[0073] Specifically, the first groove body 32 further includes an intermediate groove section 322 connected to the end of the first arc groove section 321 away from the initial position A. The second groove body 42 has a first position B 2 . When the door body 2 continues to rotate and open from the first opening angle to a preset second opening angle, as shown in Figures 6 to 9 , the first shaft body 31 moves along the intermediate groove section 322 in a direction away from the first arc groove section 321, driving the second shaft body 41 to move along the second groove body 42 from the starting position B 1 to the first position B 2 , at this time, the door body 2 is in the first translation stage. That is, the door body 2 first moves inward along the third direction F while translating inward along the second direction F 2 and 3Move backward in the direction towards the box body 1, first along the third direction F 3 Move backward in the direction towards the box body 1, and then along the fourth direction F 4 Move forward in the direction away from the box body 1. Of course, it is not limited thereto. It can be understood that in the first translation stage, the door body 2 can also be set to move along the second direction F 2 While translating inward, it always moves backward in the direction towards the box body 1 along the third direction F 3 Move backward in the direction towards the box body 1.

[0074] Specifically, the middle groove section 322 extends obliquely from the connecting part with the first arc groove section 321 towards the door lining and towards the connecting end P. The second groove body 42 starts from the starting position B 1 Extends obliquely towards the connecting end P and towards the door panel 23 to the first position B 2 .

[0075] In a specific embodiment, the second opening angle is less than 90°. Of course, it is not limited thereto.

[0076] Specifically, the second groove body 42 further includes a second position B 1 Away from the first position B 2 On one side. When the door body 2 continues to open from the second opening angle to the third opening angle, as shown in combination 3 . The first shaft body 31 continues to move along the middle groove section 322 in the direction away from the first arc groove section 321, driving the second shaft body 41 to move along the second groove body 42 from the first position B Figures 9 to 11 Through the starting position B 2 To the second position B 1 . At this time, the door body 2 is in the second translation stage. While the door body 2 moves outward along the first direction F1, it moves backward in the direction towards the box body 1 along the third direction F 3 . 3 Move backward in the direction towards the box body 1.

[0077] It can be known that during the process of the first shaft body 31 moving unidirectionally along the first groove body 32, the second shaft body 41 has a reciprocating stage of reciprocating movement in the second groove body 42, that is, during the process of the first shaft body 31 moving along the middle groove section 322, the second shaft body 41 moves from the starting position B 1 To the first position B 2 , and then from the first position B 2 Move towards the starting position B 1 Reciprocating movement.

[0078] Specifically, the second groove body 42 starts from the starting position B1 It extends obliquely in a direction away from the connection end P and towards the door lining to the second position B 3 .

[0079] In a specific embodiment, the starting position B 1 , the first position B 2 , the second position B 3 are located on the same straight line.

[0080] In a specific embodiment, the third opening angle is 90°. Of course, this is not the limit.

[0081] The first groove body 32 further includes a second arc groove section 323, the second groove body 42 has a third arc groove section 421, and the projection of the center of the third arc groove section 421 on the plane where the first hinge assembly 3 is located coincides with the center of the second arc groove section 323; during the process of the door body 2 rotating from a preset opening angle to the maximum opening angle, as shown in Figures 11 to 13 , the first shaft body 31 moves along the second arc groove section 323, and the second shaft body 41 moves along the third arc groove section 421. At this time, the door body 2 rotates in place around the center of the second arc groove section 323 / the center of the third arc groove section 421.

[0082] It can be known that the center of the second arc groove section 323 / the center of the third arc groove section 421 is a virtual axis, that is, when the first shaft body 31 moves along the second arc groove section 323 and the second shaft body 41 moves along the third arc groove section 421, the door body 2 rotates in place around the virtual axis.

[0083] In a specific embodiment, the second arc groove section 323 is connected to one end of the middle groove section 322 away from the first arc groove section 321, and the third arc section is connected to the second position B 3 , that is, the above-mentioned preset opening angle is the above-mentioned third opening angle. During the process of the door body 2 continuing to rotate from the third opening angle to the maximum opening angle, that is, at the end stage of the rotation and opening of the door body 2, the first shaft body 31 moves along the second arc groove section 323, and the second shaft body 41 moves along the third arc groove section 421. At this time, the door body 2 rotates in place around the virtual axis, that is, the door body 2 rotates in place around the center of the second arc groove section 323 / the center of the third arc groove section 421.

[0084] Specifically, the curvature of the first arc groove section 321 is greater than the curvature of the middle groove section 322, and the curvature of the second arc groove section 323 is greater than the curvature of the middle groove section 322.

[0085] Specifically, the second arc groove section 323 extends tortuously from the end of the middle groove section 322 away from the first arc groove section 321 towards the connection end P and towards the door panel 23. The third arc groove section 421 extends tortuously from the second position B 3 towards the door lining and towards the connection end P.

[0086] In some alternative embodiments, along the arrangement direction of the first hinge assembly 3 and the second hinge assembly 4, the end portions of the door side wall 22 and the door panel 23 extend beyond the plane of the mounting end face 21. In a specific embodiment, the upper ends of the door side wall 22 and the door panel 23 extend upwards beyond the upper mounting end face, so that the first hinge assembly 3 is hidden inside the door body 2 and will not be exposed outwardly. That is, the first hinge assembly 3 cannot be seen from the front side and the left and right sides of the door body 2, improving the overall appearance effect of the storage device 100. Of course, this is not limiting. In other embodiments, the lower ends of the door side wall 22 and the door panel 23 can also be arranged to extend downwards beyond the lower mounting end face, so that the second hinge assembly 4 is hidden inside the door body 2 and will not be exposed outwardly. That is, the second hinge assembly 4 cannot be seen from the front side and the left and right sides of the door body 2, improving the overall appearance effect of the storage device 100.

[0087] In some alternative embodiments, in combination with Figure 2 and Figure 14 as shown, the hinge plate 33 has a relief portion 331 for making way for the door side wall 22. Thus, during the process of the door body 2 rotating and opening, there will be no interference between the door body 2 and the hinge plate 33.

[0088] Specifically, the hinge plate 33 is L-shaped.

[0089] In a specific embodiment, the relief portion 331 is arc-shaped, and the radius of the relief portion 331 is 3 mm to 6 mm. This can avoid the hinge plate 33 being easily broken due to stress concentration. At the same time, it can also avoid interference between the door body 2 and the hinge plate 33 during the process of the door body 2 rotating and opening.

[0090] Specifically, the relief portion 331 includes a first relief portion 3311 away from the connection end P and a second relief portion 3312 close to the connection end P. That is, the first relief portion 3311 and the second relief portion 3312 together form the relief portion 331. The radius of the first relief portion 3311 is 3 mm to 6 mm, and the radius of the second relief portion 3312 is 3 mm to 5 mm.

[0091] It is known that when only the upper ends of the door side walls 22 and the door panel 23 are set to extend upward beyond the upper mounting end face, it is only necessary to provide the relief portion 331 on the first hinge plate 33a.

[0092] In summary, for the storage device 100 in the present application, by providing two hinge assemblies with single axes and single grooves (the first hinge assembly 3 and the second hinge assembly 4) to jointly guide the movement of the door body 2, the opening angle and the movement trajectory of the door body 2 can be controlled, interference with external environmental components during the rotation and opening of the door body 2 can be avoided, so that the storage device 100 is suitable for an embedded usage scenario; at the same time, the volume of each hinge assembly can be reduced.
