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.

[0032] The terms first, second, third, fourth, fifth, 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.

[0033] Please refer to Figure 1-Figure 2As 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.

[0034] 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.

[0035] Combination Figure 2 As shown, in the present invention, 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, realizing the zero-distance flat embedding of the refrigerator 100, thereby improving the integration effect of the refrigerator 100 and the home decoration.

[0036] The door body 2 has a pivot end face 21 close to the hinge assembly 3 and rotatable relative to the box body 1, a mounting end face 22 for mounting 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 rear wall face 24 closes the opening side, and at the same time, the front wall face 23 and the rear wall face 24 are almost parallel to the plane where the opening side is located.

[0037] 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.

[0038] 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.

[0039] Specifically, when the hinge assembly 3 is disposed on the right side of the box body 1 and the door body 2, the pivot end surface 21 refers to the right end surface 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 pivot end surface 21 refers to the left end surface 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 rear of the box body 1, and the third direction F3 is the direction away from the box body 1 forward.

[0040] Furthermore, the hinge assembly 3 includes a rotating shaft and a guide groove that cooperate with each other. During the process of rotating and opening the door body 2, the rotating shaft and the guide groove move relative to each other to control the movement trajectory of the door body, thereby avoiding interference between the door body 2 and the box body 1 or the cabinet 200.

[0041] In a specific embodiment, in combination Figure 3 to Figure 7 As shown, 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 move along a preset trajectory by the cooperation of 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 very high installation accuracy, which can greatly reduce the design cost and installation difficulty. Of course, it is not limited to this. In other embodiments, the hinge assembly may also be provided with only one rotating shaft and a guide groove that cooperates with the rotating shaft, or the hinge assembly may include a guide groove, two rotating shafts that cooperate with the guide groove, etc.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] Furthermore, in the first in-situ rotation stage when the door body 2 rotates from the closed state to open, the door body 2 rotates in-situ around a first rotation axis located on the first reference plane M1 or on the side of the first reference plane M1 away from the box body 1, and the first rotation axis is parallel to the outer edge 25. When the door body 2 is in the closed state, the outer edge 25 is located on the first reference plane M1, and the first reference plane M1 is parallel to the plane where the opening side is located. Figure 3-4As shown, at the initial stage of the door body 2 rotating from the closed state to open, the door body 2 rotates in situ around the first rotation axis. At this time, the outer edge 25 rotates around the rotation axis along the first direction F1 away from the cabinet 200 located at the pivot end, thereby avoiding interference between the door body 2 and the cabinet 200; at the same time, compared with the existing door body 2 whose first rotation axis is located on the side of the first reference plane M1 close to the box body 1, the extent of the inner edge 26 protruding toward the box body 1 during the rotation of the door body 2 is reduced, which can avoid interference between the inner edge 26 and the box body 1 and avoid excessive extrusion between the door body 2 and the box body 1. The structure is simple, and the movement of the door body 2 is relatively stable, which is convenient for opening the door body 2.

[0048] It is known that in an embodiment where the front wall surface 23 is parallel to the plane where the opening side is located when the door body 2 is in a closed state, the above-mentioned first reference plane M1 refers to the plane where the front wall surface 23 is located when the door body 2 is in a closed state.

[0049] Specifically, the first guide groove 33 includes a first arc groove 331, and the second guide groove 34 includes a second arc groove 341. The centers of the first arc groove 331 and the second arc groove 341 are located on the first rotation axis. When the door body 2 rotates in situ around the first rotation axis, the first rotating shaft 31 moves in the first arc groove 331, and the second rotating shaft 32 moves in the second arc groove 341.

[0050] In an embodiment where both the first circular arc groove 331 and the second circular arc groove 341 are disposed on the mounting end surface 22 , the center of the first circular arc groove 331 and the center of the second circular arc groove 341 are the same.

[0051] Specifically, the first arc groove 331 includes a first end and a second end opposite to each other, and the second arc groove 341 includes a third end and a fourth end opposite to each other. When the door body 2 is in a closed state, the first rotating shaft 31 is located at the first end, and the second rotating shaft 32 is located at the third end. When the door body 2 rotates to open from the closed state, the first rotating shaft 31 moves from the first end along the first arc groove 331 to the second end, and the second rotating shaft 32 moves from the third end along the second arc groove 341 to the fourth end.

[0052] In a specific embodiment, the first rotation axis is located on a side of the reference plane away from the box body 1 , that is, the distance between the first rotation axis and the reference plane is greater than 0 mm, which has a better effect of avoiding interference between the door body 2 and the cabinet 200 .

[0053] Further, the first rotation axis is located on the side of the second reference plane M2 facing the opening side, the second reference plane M2 is perpendicular to the first reference plane M1, and the second reference plane M2 intersects with the first reference plane M1 at the outer edge 25 in the closed state of the door body 2. When the door body 2 rotates in situ around the first rotation axis from the closed state to open, the outer edge 25 will rotate along the second direction F2 toward the direction close to the box body 1, which can control the distance between the door body 2 and the box body 1, avoid the center of gravity of the door body 2 from deviating too much from the box body 1, maintain the consistency of the door body 2 and the box body 1, and avoid the door body 2 from tilting.

[0054] It can be known that when the door body 2 is in a closed state, the pivot end surface 21 overlaps with the second reference surface M2.

[0055] Combination Figure 3 As shown, the first arc groove 331 is formed extending from the first end toward the rear wall surface 24 and the pivot end surface 21, and the distance between the first end and the front wall surface 23 is smaller than the distance between the second end and the front wall surface 23. The second arc groove 341 is located on the side of the first arc groove 331 close to the rear wall surface 24, and the distance between the third end and the front wall surface 23 is smaller than the distance between the first end and the front wall surface 23, which is conducive to the smooth opening of the door body 2; at the same time, more design space can be given to the first guide groove 33 and the second guide groove 34 to increase the opening degree of the door body 2.

[0056] It can be known that the radius of the first circular arc groove 331 is smaller than the radius of the second circular arc groove 341 , and correspondingly, the length of the first circular arc groove 331 is smaller than the length of the second circular arc groove 341 .

[0057] Furthermore, after the first in-situ rotation stage, the door body 2 also has a second in-situ rotation stage of rotating around a second rotation axis and a third in-situ rotation stage of rotating around a third rotation axis in sequence; wherein the second rotation axis and the third rotation axis are both located on the side of the first reference plane facing the box body 1, and the distance between the second rotation axis and the outer edge is smaller than the distance between the third rotation axis and the outer edge. The door body 2 can be opened to a larger angle, the opening of the door body 2 is increased, and interference between the door body 2 and the box body 1 and the cabinet can be further avoided.

[0058] Specifically, the first guide groove 33 has a first pivot position L1 located at the second end away from the first end, and the second guide groove 34 also includes a third arc groove 342 connected to the fourth end and extending in a direction away from the third end, and the third arc groove 342 takes the first rotating shaft 31 located at the first pivot position L1 as the center. The first rotating shaft 31 located at the first pivot position L1 is located on the second rotation axis. Figure 5-6 As shown, after the door body 2 rotates and opens until the first rotating shaft 31 moves out of the first arc groove 331 and is located at the first pivot position L1, the first rotating shaft 31 remains at the first pivot position L1, and the second rotating shaft 32 moves along the third arc groove 342. At this time, the door body 2 rotates in situ around the first rotating shaft 31 located at the first pivot position L1, and the door body 2 is in the second in situ rotation stage, so that the door body 2 can quickly open a larger angle, which can increase the opening of the door body 2, so that the door body 2 can be opened at a larger angle, and the distance between the door body 2 and the box body 1 can be controlled to avoid the center of gravity of the door body 2 deviating too much from the box body 1, maintain the consistency of the door body 2 and the box body 1, and avoid the door body 2 from tilting.

[0059] Specifically, in an embodiment where both the first guide groove 33 and the second guide groove 34 are located on the mounting end surface 22 , the center of the third arc groove 342 is the first pivot position L1 .

[0060] Further, the end of the third circular arc groove 342 away from the second circular arc groove 341 has a second pivot position L2, and the first guide groove 33 also includes a fourth circular arc groove 332 extending from the first pivot position L1 toward the first circular arc groove 331, and the fourth circular arc groove 332 takes the second rotating shaft 32 located at the second pivot position L2 as the center. The second rotating shaft 32 located at the second pivot position L2 is on the third rotation axis. Figure 6-7 As shown, after the door body 2 rotates and opens until the second rotating shaft 32 moves to the second pivot position L2 along the third circular arc groove 342, the second rotating shaft 32 remains at the second pivot position L2, and the first rotating shaft 31 moves along the fourth circular arc groove 332 toward the direction where the first circular arc groove 331 is located. At this time, the door body 2 rotates in situ around the second rotating shaft 32 located at the second pivot position L2, and the door body 2 is in the third in-situ rotation stage, making full use of the space between the first guide groove 33 on the mounting surface and the front wall surface 23, which can further increase the opening of the door body 2, so that the door body 2 can be opened at a larger angle.

[0061] Specifically, in an embodiment in which both the first guide groove 33 and the second guide groove 34 are located on the mounting end surface 22 , the center of the fourth arc groove 332 is the second pivot position L2 .

[0062] In a specific embodiment, after the door body 2 rotates open until the second rotating shaft 32 is maintained at the second pivot position L2, and the first rotating shaft 31 moves along the fourth circular arc groove 332 toward the direction of the first circular arc groove 331 to the end of the fourth circular arc groove 332 close to the first circular arc groove 331, the door body 2 opens to the maximum opening angle of 135°, which can achieve a large-angle door opening without causing interference with the cabinet 200 and the box body 1.

[0063] Further, when the door body 2 rotates and opens until the first rotating shaft 31 is located at the second end, the second rotating shaft 32 is located at the fourth end and continues to rotate and open, the hinge assembly 3 drives the door body 2 to translate along a preset trajectory until the first rotating shaft 31 moves to the first pivot position L1. That is, between the first in-situ rotation stage and the second in-situ rotation stage, the door body 2 also has a translation stage of translating along a preset trajectory to control the trajectory of the door body 2, so that the door body 2 has space to open to a larger angle later, and at the same time, avoid interference between the door body 2 and the cabinet 200 and the box body 1.

[0064] In a specific embodiment, the translation direction of the preset trajectory has directional components in the first direction F1 and the third direction F3. That is, during the process of the door body 2 rotating and opening, the door body 2 moves along the first direction F1 in a direction away from the cabinet 200 at the pivot end, increasing the distance between the door body 2 and the cabinet 200 at the pivot end; at the same time, the door body 2 moves forward along the third direction F3 in a direction away from the box body 1, increasing the distance between the door body 2 and the front end surface of the cabinet 200 at the pivot end, so that the door body 2 has space to open a larger angle later, and at the same time, avoiding interference between the door body 2 and the cabinet 200 and the box body 1.

[0065] Corresponding, combined Figure 4-5 As shown, the first guide groove 33 also includes a first groove section 333 connecting the second end and the first pivot position L1, and the second guide groove 34 also includes a second groove section 343 connecting the fourth end and the third arc groove 342; when the first rotating shaft 31 moves in the first groove section 333 and the second rotating shaft 32 moves in the second groove section 343, the door body 2 rotates and translates according to a preset trajectory.

[0066] Combination Figure 3-4As shown, at the initial stage of the door body 2 rotating to open, the door body 2 is in the first in-situ rotation stage, the first rotating shaft 31 moves from the first end along the first arc groove 331 to the second end, and the second rotating shaft 32 moves from the third end along the second arc groove 341 to the fourth end. At this time, the door body 2 rotates in situ around the rotation axis corresponding to the center of the first arc groove 331 / second arc groove 341, and the outer edge 25 moves away from the cabinet 200 along the first direction F1 and toward the box body 1 along the second direction F2, which can avoid interference between the door body 2 and the box body 1 and the cabinet 200, while maintaining the consistency between the door body 2 and the box body 1. Combined with Figure 4-5 As shown, in the early and middle stages of the door body 2 rotating to open, the door body is in the translation stage, the first rotating shaft 31 moves along the first slot section 333 to the first pivot position L1, and the second rotating shaft 32 moves along the second slot section 343. At this time, the door body 2 translates in the first direction F1 and the third direction F3 while rotating, increasing the distance between the door body 2 and the cabinet 200 at the pivot end and the distance between the door body 2 and the front end face of the cabinet 200 at the pivot end, so that the door body 2 has space to open to a larger angle later. Figure 5-6 As shown, in the middle and late stages of the door body 2 rotating to open, the door body 2 is in the second in-situ rotation stage, the first rotating shaft 31 remains at the first pivot position L1, the second rotating shaft 32 moves along the third circular arc groove 342 to the second pivot position L2, and the door body 2 rotates around the first rotating shaft 31 at the first pivot position L1 to increase the opening of the door body 2. Figure 6-7 As shown, in the later stage of the door body 2 rotating to open, the door body is in the third in-situ rotation stage, the second rotating shaft 32 is maintained at the second pivot position L2, the first rotating shaft 31 moves in the fourth arc groove 332, and the door body 2 rotates around the second rotating shaft 32 located at the second pivot position L2, further increasing the opening of the door body 2.

[0067] Furthermore, the first groove section 333 and the second groove section 343 are both arc-shaped grooves, which can improve the smoothness of the movement of the door body 2 and avoid jamming during the door body 2 rotation and opening process.

[0068] Specifically, the first groove section 333 extends obliquely from the second end toward the pivot end face and toward the outer edge 25, and the second groove section 343 extends obliquely from the fourth end toward the pivot end face and toward the outer edge 25, so that the door body 2 can translate according to the preset trajectory, and at the same time, it is also convenient for the subsequent setting of the fourth arc groove 332.

[0069] To summarize, the storage device of the present invention has a double-slot double-axis structure, and the rotation axis of the door body 2 is set on the side of the first reference plane M1 away from the box body 1, so that in the initial stage of the door body 2 rotating to open from a closed state, the outer edge 25 rotates around the rotation axis along the first direction F1 away from the cabinet 200 located at the pivot end, thereby avoiding interference between the door body 2 and the cabinet 200; at the same time, compared with the existing door body 2 whose rotation axis is located on the side of the first reference plane M1 close to the box body 1, the extent of the inner edge 26 protruding toward the box body 1 during the rotation of the door body 2 is reduced, which can avoid interference between the inner edge 26 and the box body 1, and avoid excessive extrusion between the door body 2 and the box body 1.
