[0043] The present invention will be described in detail below in conjunction with the various embodiments shown in the accompanying drawings. Figure 1-Figure 7 , which are preferred embodiments of the present invention, wherein the same or similar reference numerals throughout 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 of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present invention.

[0044] In the illustrations of the present invention, for the sake 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. At the same time, the arrows shown in the drawings are the moving directions of the rotating shafts.

[0045] 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.

[0046] The terms first, second, third, etc. in the present invention are only used for descriptive purposes to distinguish these description objects from each other, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0047] Please refer to Figure 1-Figure 7 As shown, the present invention provides a storage device, including a box body 1, a door body 2 for opening and closing the opening side of the box body 1, and a hinge assembly 3 for rotatably connecting the door body 2 to the box body 1. The box body 1 is used to provide a storage space for customers to store and retrieve items. The door body 2 is used to open or close the box body 1 from the opening side. The hinge assembly 3 is used to provide guidance for the movement of the door body 2, control the opening angle and movement trajectory of the door body 2, so as to prevent interference between the door body 2 and external environmental parts during the opening and closing process, so that the storage device can be embedded in a wall, a cabinet 200, etc., and can even be embedded flatly with zero distance.

[0048] When the storage device is embedded in a wall or cabinet 200, the external environment member mentioned above refers to the corresponding wall or cabinet 200. The above-mentioned zero-distance flush embedding means that the gap between the storage device and the wall / cabinet 200 is 0 mm, and when the door body 2 is in a closed state, the front wall surface 23 of the door body 2 is flush with the front end surface of the wall / cabinet 200.

[0049] In a specific embodiment, the storage device is a refrigerator 100 embedded in a cabinet 200. In this case, the refrigerator 100 further includes a refrigeration system for providing cold air to the refrigerator 100. With the assistance of the refrigeration system, a refrigeration compartment can be formed in the refrigerator 100. At the same time, the refrigerator 100 may also include shelves, drawers, bottle holders, etc. arranged in the refrigeration compartment to enable partitioned storage of corresponding items. Of course, it is understandable that this is not limited to the above. The storage device in this article is not necessarily a refrigerator 100, but may also be other household appliances such as a microwave oven and a wardrobe. At the same time, the storage device in this article is not necessarily embedded in the cabinet 200, and may be used alone or embedded in other external environment parts such as a wall.

[0050] It should be noted that the drawings in the specification of the present invention only show the cabinet 200 located at the pivot end surface 21 of the door body 2. In actual installation, the refrigerator 100 is completely embedded in the cabinet 200. Figure 2 As shown, after the refrigerator 100 is embedded in the cabinet 200, the gap between the refrigerator 100 and the cabinet 200 is 0 mm, and when the door body 2 is in a closed state, the front wall surface 23 of the door body 2 away from the box body 1 is flush with the front end surface of the cabinet 200, thereby realizing seamless embedding of the refrigerator 100 and improving the integration effect of the refrigerator 100 and home decoration.

[0051] The door body 2 has a pivot end face 21 close to the hinge assembly 3 and rotatable relative to the box body 1, and the box body 1 has a pivot side wall 11 corresponding to the pivot end face 21. When the door body 2 is in a closed state, the pivot end face 21 and the pivot side wall 11 are located in the same plane. The above-mentioned gap between the refrigerator 100 and the cabinet 200 is 0 mm after the refrigerator 100 is embedded in the cabinet 200, which means that when the door body 2 is in a closed state, the gap between the pivot side wall 11 / pivot end face 21 and the cabinet 200 is 0 mm, so that the refrigerator 100 is embedded without a gap.

[0052] Specifically, the door body 2 has a mounting end face 22 connected to the pivot end face 21 and used to mount the hinge assembly 3, a front wall face 23 connected to the pivot end face 21 and the mounting end face 22 at one end away from the box body 1, a rear wall face 24 connected to the pivot end face 21 and the mounting end face 22 at one end close to the box body 1, and a free end face opposite to the pivot end face 21. When the door body 2 is in a closed state of closing the opening side, the front wall face 23 and the rear wall face 24 are almost parallel to the plane where the opening side is located, and at the same time, the rear wall face 24 closes the opening side.

[0053] The connection between the front wall surface 23 and the pivot end surface 21 forms an outer edge 25, and the connection between the rear wall surface 24 and the pivot end surface 21 forms an inner edge 26, and the inner edge 26 is almost parallel to the outer edge 25. It can be known that the inner edge 26 is the end of the pivot end surface 21 close to the opening side when the door body 2 is in the closed state, and the outer edge 25 is the end of the pivot end surface 21 away from the opening side when the door body 2 is in the closed state.

[0054] When the door body 2 is in a closed state closing the opening side, the direction from the pivot end face 21 toward the free end face is defined as a first direction F1, the direction from the door body 2 toward the opening side and perpendicular to the opening side is defined as a second direction F2, and the direction opposite to the second direction F2 is defined as a third direction F3.

[0055] Specifically, when the hinge assembly 3 is disposed on the right side of the box body 1 and the door body 2, the rotation end face refers to the right end face of the door body 2, and the first direction F1 is the direction away from the cabinet 200 on the right side to the left. When the hinge assembly 3 is disposed on the left side of the box body 1 and the door body 2, the rotation end face refers to the left end face of the door body 2, and the first direction F1 is the direction away from the cabinet 200 on the left side to the right. The second direction F2 is the direction towards the back of the box body 1, and the third direction F3 is the direction away from the box body 1 forward.

[0056] Furthermore, in the process of the door body 2 rotating and opening from the closed state, the hinge assembly 3 drives the door body 2 to move first along the first translation trajectory and then along the second translation trajectory, wherein the first translation trajectory has a directional component in the first direction F1, and the second translation trajectory has a directional component in the first direction F1 and a direction perpendicular to the plane where the opening side is located. That is, in the early stage of the process of the door body 2 rotating and opening from the closed state, the door body 2 first moves along the first direction F1 in a direction away from the cabinet 200 located at the pivot end, so that in the process of the door body 2 rotating and opening, the outer edge 25 will not protrude too much toward the cabinet 200 located at the pivot end, thereby preventing interference between the door body 2 and external environmental components, especially the cabinet 200 located at the pivot end. In the middle stage of the door body 2 rotating to open from the closed state, the door body 2 moves along the first direction F1 away from the cabinet 200 located at the pivot end and at the same time moves in a direction perpendicular to the plane where the opening side is located, thereby further increasing the distance between the front wall 23 of the door body 2 and the cabinet 200 to avoid interference and, at the same time, facilitate opening the door at a large angle.

[0057] In this embodiment, the second translation trajectory has directional components in the first direction F1 and the second direction F2. That is, in the middle stage of the door body 2 rotating and opening from the closed state, there is a certain gap between the inner edge 26 and the box body 1, and when the door body 2 continues to rotate and open, the inner edge 26 will move in the direction away from the box body 1. At this time, the door body 2 moves along the first direction F1 in the direction away from the cabinet 200 located at the pivot end, and moves along the second direction F2 in the direction close to the box body 1, increasing the distance between the front wall surface 23 of the door body 2 and the cabinet 200, which is conducive to opening the door at a large angle. At the same time, the center of gravity of the door body 2 moves backward in the direction close to the box body 1, maintaining the consistency of the door body 2 and the box body 1, and preventing the door body 2 from tipping over. Of course, this is not limited to this. In other embodiments, the second translation trajectory mentioned above can also have directional components in the first direction F1 and the third direction F3 at the same time.

[0058] Further, the first translation trajectory has directional components in the first direction F1 and the third direction F3. That is, at the beginning of the process of the door body 2 rotating and opening from the closed state, the door body 2 moves along the first direction F1 in the direction away from the cabinet 200 at the pivot end, and at the same time, the door body 2 moves forward along the third direction F3 in the direction away from the box body 1. It is known that at the beginning of the door body 2 rotating and opening, the inner edge 26 will rotate toward the box body 1, and the distance between the inner edge 26 and the box body 1 will gradually decrease. Therefore, setting the door body 2 to move forward along the third direction F3 in the direction away from the box body 1 can simultaneously keep the inner edge 26 of the door body 2 from protruding too much toward the box body 1 at the beginning of opening, and there will be no interference between the inner edge 26 and the box body 1, especially, the seal or other decorative parts between the door body 2 and the box body 1 will not be squeezed too much.

[0059] Combination Figure 3 As shown, during the movement of the door body 2 according to the first translation trajectory, the outer edge trajectory line L1 of each point on the outer edge 25 has a small curvature and is located on the side of the plane where the pivoting side wall 11 is located facing the box body 1. Therefore, during the rotation and opening of the door body 2, no interference will occur between the outer edge 25 and the cabinet 200. After the door body 2 moves according to the first translation trajectory and the door body 2 continues to rotate, the outer edge trajectory line L1 of each point on the outer edge 25 of the door body 2 extends obliquely toward the box body 1 and away from the cabinet 200 along the first direction F1. No interference will occur between the door body 2 and the cabinet 200.

[0060] Specifically, when the door body 2 moves along the first translation trajectory, the outer edge trajectory line L1 of each point on the outer edge 25 is nearly a straight line, and the trajectory line is perpendicular to the plane where the opening side is located.

[0061] During the process of the door body 2 rotating and opening from the closed state, the inner edge trajectory line L2 of each point on the inner edge 26 includes a first arc segment L21 extending obliquely toward the box body 1, a second segment L22 parallel to the plane where the opening side is located, and a third arc segment L23 extending obliquely in the direction away from the box body 1. The curvature of the second segment L22 is small and is a straight line segment, and the second segment L22 is spaced from the opening side. In this way, during the process of the door body 2 rotating and opening, the door body 2 will not excessively squeeze the box body 1, and no interference will occur between the door body 2 and the box body 1.

[0062] Further, in the first stage when the door body 2 moves along the first translation trajectory, during the process when the door body 2 rotates to open, the translation amount of the door body 2 in the third direction F3 is greater than the translation amount in the first direction F1. That is, in the first stage of the door body 2 rotating and opening from the closed state, relative to the translation amount of the door body 2 moving along the first direction F1 toward the direction away from the cabinet 200 located at the pivot end, the forward movement amount of the door body 2 away from the box body 1 is larger, and correspondingly, the forward door-opening force when opening the door is larger, which is conducive to the smooth opening of the door body 2 and can avoid interference between the inner edge 26 and the box body 1; at the same time, in the first stage of the door body 2 rotating and opening from the closed state, the outward protrusion amount of the outer edge 25 toward the cabinet 200 located at the pivot end is also smaller, so a small amount of translation in the first direction F1 can avoid interference between the outer edge 25 and the cabinet 200, and a small amount of translation in the first direction F1 can also reduce the translation amount of the door body 2 in the first direction F1 during the overall door opening process, so as to avoid excessive shielding of the opening side by the door body 2 when the door body 2 is opened to the maximum opening angle, and will not interfere with drawers, etc., which is convenient for taking and placing items, and will not cause obvious displacement problems when the door body 2 is opened, and the movement of the door body 2 is more stable.

[0063] Furthermore, in the second stage after the first stage when the door body 2 moves according to the first translation trajectory, during the process of the door body 2 rotating to open, the translation amount of the door body 2 in the third direction F3 is less than the translation amount in the first direction F1. That is, in the second stage when the door body 2 rotates to open from the closed state, at this time, the door body 2 is already in the open state, and the translation amount of the door body 2 moving along the first direction F1 away from the cabinet 200 at the pivot end is larger than the forward movement amount of the door body 2 away from the box body 1. It is possible to avoid interference between the outer edge 25 and the cabinet 200 and between the inner edge 26 and the box body 1, increase the distance between the front wall 23 of the door body 2 and the cabinet 200, and help increase the opening of the door body 2, that is, increase the maximum opening angle of the door body 2.

[0064] Furthermore, when the door body 2 moves according to the first translation trajectory and is in the third stage after the second stage, during the process of the door body 2 rotating to open, the translation amount of the door body 2 in the third direction F3 is greater than the translation amount of the first direction F1. That is, in the third stage of the door body 2 self-rotating to open, relative to the translation amount of the door body 2 moving in the first direction F1 away from the cabinet 200 at the pivot end, the forward movement of the door body 2 away from the box body 1 is larger, so that the door body 2 has space to open a larger angle, and it can ensure that the door body 2 will not interfere with the cabinet 200 and the box body 1; at the same time, it can provide a margin for a small amount of subsequent backward movement.

[0065] Furthermore, in the process of the door body 2 moving along the second translation trajectory, the translation amount of the door body 2 in the first direction F1 is greater than the translation amount in the second direction F2. That is, when the door body 2 rotates to open and moves along the second translation trajectory, the translation amount of the door body 2 moving along the first direction F1 away from the cabinet 200 at the pivot end is greater than the backward movement amount of the door body 2 along the second direction F2 to approach the box body 1, so that the door body 2 has space to open a larger angle, and it can be ensured that the door body 2 will not interfere with the cabinet 200 and the box body 1; at the same time, the center of gravity of the door body 2 can be moved backward in the direction close to the box body 1, maintaining the consistency of the door body 2 and the box body 1, and preventing the door body 2 from tipping over.

[0066] Specifically, the hinge assembly 3 includes a first guide structure and a second guide structure, wherein the first guide structure includes a first rotating shaft 31 and a first guide groove 33 that cooperate with each other, and the second guide structure includes a second rotating shaft 32 and a second guide groove 34 that cooperate with each other. In the present invention, the door body 2 is driven to translate along a preset translation trajectory during the rotation and opening process by cooperating with the double shafts (the first rotating shaft 31 and the second rotating shaft 32) and the double grooves (the first guide groove 33 and the second guide groove 34). Compared with a single-axis hinge, it does not require high installation precision, which can greatly reduce the design cost and installation difficulty.

[0067] Specifically, one of the first rotating shaft 31 and the first guide groove 33 is disposed on the box body 1, and the other is disposed on the door body 2. One of the second rotating shaft 32 and the second guide groove 34 is disposed on the box body 1, and the other is disposed on the door body 2.

[0068] That is to say, the distribution of the rotating shaft and the guide groove may include four situations. In the first example, the first rotating shaft 31 and the second rotating shaft 32 are located in the box body 1, and the first guide groove 33 and the second guide groove 34 are provided in the door body 2; in the second example, the first rotating shaft 31 and the second rotating shaft 32 are located in the door body 2, and the first guide groove 33 and the second guide groove 34 are provided in the box body 1; in the third example, the first rotating shaft 31 and the second guide groove 34 are provided in the box body 1, and the first guide groove 33 and the second rotating shaft 32 are provided in the door body 2; in the fourth example, the first rotating shaft 31 and the second guide groove 34 are provided in the door body 2, and the second rotating shaft 32 and the first guide groove 33 are provided in the box body 1.

[0069] The specific structure of the rotating shaft and the guide groove is described herein by taking the first example as an example, that is, the first rotating shaft 31 and the second rotating shaft 32 are located in the box body 1, and the first guide groove 33 and the second guide groove 34 are located in the door body 2. Of course, this is not limited to this.

[0070] Specifically, the hinge assembly 3 includes a hinge plate fixed on the box body 1, the hinge plate is opposite to the mounting end surface 22, the first rotating shaft 31 and the second rotating shaft 32 are both fixed on the side of the hinge plate facing the mounting end surface 22, and the first guide groove 33 and the second guide groove 34 are both provided on the mounting end surface 22.

[0071] It is known that the first guide groove 33 and the second guide groove 34 can be formed by being recessed downward from the mounting end surface 22 , or a prefabricated sleeve can be installed on the mounting end surface 22 , and the sleeve has the first guide groove 33 and the second guide groove 34 preset thereon.

[0072] Combination Figure 4 , Figure 5 As shown, the first guide groove 33 includes an initial position 331, a first groove section 332 extending obliquely from the initial position 331 toward the inner edge 26, a second groove section 333 extending from one end of the first groove section 332 away from the initial position 331 toward the pivot end, and a third groove section 334 extending from one end of the second groove section 333 away from the first groove section 332 toward the outer edge 25, and the angle between the first groove section 332 and the pivot end face 21 is smaller than the angle between the second groove section 333 and the pivot end face 21. The second guide groove 34 includes a first position 341 located on a side of the initial position 331 away from the pivot end face 21, a first arc groove 342 extending from the first position 341 toward the inner edge 26, and a second arc groove 343 smoothly connected to one end of the first arc groove 342 away from the first position 341 and bent toward the outer edge 25. When the door body 2 is in a closed state, the first rotating shaft 31 is located at the initial position 331, and the second rotating shaft 32 is located at the first position 341; when the first rotating shaft 31 moves along the first slot section 332 and the second slot section 333 to the third slot section 334, the second rotating shaft 32 moves along the first arc-shaped slot 342, and the door body 2 moves according to a first translation trajectory; when the first rotating shaft 31 moves in the third slot section 334, the second rotating shaft 32 moves in the second arc-shaped slot 343, and the door body 2 moves according to a second translation trajectory. The junction between the first groove section 332 and the second groove section 333 is the first inflection point, the junction between the second groove section 333 and the third groove section 334 is the second inflection point, and the second arc groove 343 is the third inflection point of the second guide groove 34. During the rotation and opening of the door body 2, the first rotating shaft 31 passes through the first inflection point and the second inflection point in sequence, and then the second rotating shaft 32 passes through the third inflection point, that is, the first rotating shaft 31 and the second rotating shaft 32 pass through the inflection points of the corresponding guide grooves, so that the door body 2 moves smoothly during the opening process to avoid sliding and jamming.

[0073] Among them, the first inflection point, the second inflection point, and the third inflection point are all smooth arc-shaped grooves, so that the door body 2 can be opened smoothly to avoid jamming.

[0074] Furthermore, the first groove section 332 is an arc-shaped groove convex outwardly in a direction away from the outer edge 25, so that the door body 2 can move smoothly when opening from a closed state, avoiding the sliding jam.

[0075] Furthermore, combined with Figure 3-4 As shown, when the door body 2 rotates to open and the first rotating shaft 31 moves along the first slot section 332, the angle between the tangent line at any point of the first slot section 332 and the plane where the opening side is located gradually increases, and the angle between the tangent line at any point of the first slot section 332 and the plane where the opening side is located is not less than 45°. Therefore, when the door body 2 rotates to open and the first rotating shaft 31 moves along the first slot section 332, the door body 2 has direction components in the first direction F1 and the third direction F3, and at the same time, the translation amount of the door body 2 in the third direction F3 is greater than the translation amount of the first direction F1. That is, when the door body 2 rotates to open and the first rotating shaft 31 moves along the first slot section 332, it corresponds to the first stage of the movement of the door body 2 according to the first translation trajectory.

[0076] It is known that, in the above-mentioned process of rotating and opening the door body 2, the angle between the tangent of any point of the first groove section 332 and the reference plane can also be understood as the angle between the moving trajectory line / moving direction of the first rotating shaft 31 and the reference plane.

[0077] Further, when the first rotating shaft 31 is located at the first inflection point, the opening angle of the door body 2 is not greater than 30°. In a specific embodiment, when the first rotating shaft 31 is located at the first inflection point, the opening angle of the door body 2 is 30°. Of course, this is not limited thereto.

[0078] Furthermore, the second slot section 333 is a straight slot perpendicular to the plane where the pivot end surface 21 is located. When the door body 2 rotates and opens until the first shaft 31 moves in the second slot section 333 toward the third slot section 334 , the second shaft 32 moves along the first arc slot 342 .

[0079] It is known that during the rotation of the door body 2, the angle between the second slot section 333 and the plane where the opening side is located gradually increases. Before the door body 2 rotates to 45°, the angle between the second slot section 333 and the plane where the opening side is located is less than 45°. During this process, if the first rotating shaft 31 moves toward the third slot section 334 in the second slot section 333, the translation direction of the door body 2 will have direction components of the first direction F1 and the third direction F3, and the translation amount of the door body 2 in the third direction F3 is less than the translation amount of the first direction F1. That is, the process in which the door body 2 rotates to open and the first rotating shaft 31 moves along the second slot section 333 until the door body 2 opens to 45° corresponds to the second stage in which the door body 2 moves according to the first translation trajectory.

[0080] During the rotation of the door body 2, the angle between the second slot section 333 and the plane where the opening side is located gradually increases. After the door body 2 rotates to 45°, the angle between the second slot section 333 and the plane where the opening side is located is greater than 45°. During this process, if the first rotating shaft 31 moves toward the third slot section 334 in the second slot section 333, the translation direction of the door body 2 will have direction components of the first direction F1 and the third direction F3, and the translation amount of the door body 2 in the third direction F3 is greater than the translation amount of the first direction F1. That is, after the door body 2 rotates and opens 45°, the process in which the first rotating shaft 31 moves along the second slot section 333 corresponds to the third stage in which the door body 2 moves along the first translation trajectory.

[0081] In a specific embodiment, when the first rotating shaft 31 is located at the second inflection point, the opening angle of the door body 2 is less than 90°, and in a specific example, the opening angle of the door body 2 is 75°. Of course, this is not limited thereto.

[0082] Further, the third slot section 334 is a straight slot parallel to the plane where the pivot end surface 21 is located, and the third slot section 334 has a second position 3341, and when the door body 2 is opened to 90°, the first rotating shaft 31 is located at the second position 3341. Before the door body 2 is opened to 90°, the third slot section 334 extends obliquely from the second inflection point toward the third direction F3 and the fourth direction opposite to the first direction F1, and the angle between the third slot section 334 and the plane where the opening side is located is less than 45° and gradually decreases. Therefore, before the door body 2 is opened to 90° and when the first rotating shaft 31 moves in the third slot section 334 toward the direction away from the second slot section 333, the translation direction of the door body 2 has the direction components of the first direction F1 and the second direction F2, and the translation amount of the door body 2 in the first direction F1 is greater than the translation amount in the second direction F2. That is, when the first rotating shaft 31 moves in the third slot section 334 in a direction away from the second slot section 333 to the second position 3341 , the door body 2 translates along the second translation trajectory during rotation.

[0083] Furthermore, during the process of the door body 2 rotating and opening, after the hinge assembly 3 drives the door body 2 to move along the second translation trajectory, the hinge assembly 3 continues to drive the door body 2 to move along the third translation trajectory, and the third translation trajectory has directional components in the first direction F1 and the third direction F3. This allows the door body 2 to have space to open to a larger angle; at the same time, when the door body 2 continues to rotate and open from 90°, the outer edge 25 will move toward the box body 1, so that the door body 2 is set to translate a small amount in the forward direction away from the box body 1, which can ensure that the door body 2 will not interfere with the box body 1.

[0084] Specifically, when the door body 2 moves along the third translation trajectory, the translation amount of the door body 2 in the first direction F1 is greater than the translation amount in the third direction F3, so that the door body 2 has space to open to a larger angle and interference between the door body 2 and the cabinet 200 and the box body 1 can be avoided.

[0085] Specifically, when the door body 2 is in the first stage and the second stage of the first translation trajectory, the inner edge trajectory line L2 of each point on the inner edge 26 is sequentially a first arc segment L21 and a straight line segment L22 parallel to the plane where the opening side is located; when the door body 2 is gradually opened from the third segment in the first translation trajectory to the maximum opening angle, the inner edge trajectory line L2 of each point on the inner edge 26 is a second arc segment L23 extending obliquely away from the box body 1. Of course, this is not limited to this.

[0086] Correspondingly, the second guide groove 34 further includes a third arc groove 344 extending from one end of the second arc groove 343 close to the pivot end surface 21 toward the outer edge 25, and when the second rotating shaft 32 switches from the second arc groove 343 to move in the third arc groove 344, the first rotating shaft 31 continues to move along the third groove section 334. That is, the third groove section 334 has a terminal position 3342 located away from the second position 3341 and away from the second inflection point, and when the second rotating shaft 32 moves along the third arc groove 344 toward the direction close to the outer edge 25, the first rotating shaft 31 moves from the second position 3341 toward the terminal position 3342.

[0087] When the door body 2 continues to rotate from 90° to open, the angle between the third slot section 334 and the plane where the opening side is located gradually increases and is less than 45°. When the first rotating shaft 31 moves from the second position 3341 toward the terminal position 3342, the door body 2 has direction components in the first direction F1 and the third direction F3, and the translation amount of the door body 2 in the first direction F1 is greater than the translation amount in the third direction F3.

[0088] In a specific embodiment, the maximum opening angle of the door body 2 is 110°. When the door body 2 is opened to the maximum opening angle, the first rotating shaft 31 moves to the terminal position 3342, and at the same time, the second rotating shaft 32 moves to the end of the third arc groove 344 close to the outer edge 25.

[0089] Furthermore, the third arc groove 344 is located on the side of the third groove section 334 facing the rear wall surface 24. That is, the third arc groove 344 and the third groove section 334 are arranged along the front-to-back direction, and the two do not overlap in the front-to-back direction. Therefore, when the first rotating shaft 31 moves in the third groove section 334 and the second rotating shaft 32 moves in the third arc groove 344, the moving directions of the first rotating shaft 31 and the second rotating shaft 32 are almost the same, and there is less misalignment in the left-right direction, which can improve the stability of the movement of the door body 2 and reduce the shaking of the door body 2.

[0090] Furthermore, the distance between the first position 341 and the front wall surface 23 is smaller than the distance between the initial position 331 and the front wall surface 23, which is beneficial to the rapid opening of the door body 2.

[0091] In summary, the storage device in the present invention, by setting the hinge assembly 3 so that in the initial stage of the door body 2 rotating and opening from the closed state, the door body 2 first moves along the first direction F1 in the direction away from the cabinet 200 located at the pivot end, so that during the process of the door body 2 rotating and opening, the outer edge 25 will not protrude too much in the direction of the cabinet 200 located at the pivot end, thereby preventing the door body 2 from interfering with external environmental parts, especially the cabinet 200 located on the pivot end side; in the middle stage of the door body 2 rotating and opening from the closed state, the door body 2 moves along the first direction F1 in the direction away from the cabinet 200 located at the pivot end and moves along the second direction F2 in the direction close to the box body 1, thereby increasing the distance between the front wall 23 of the door body 2 and the cabinet 200, which is conducive to opening the door at a large angle, and at the same time, the center of gravity of the door body 2 moves backward in the direction close to the box body 1, thereby maintaining the consistency between the door body 2 and the box body 1 and preventing the door body 2 from tipping over.
