[0035] In the related art, for the refrigerator door body which needs to be embedded for use, the hinge structure generally adopted is complex, high in cost, low in door opening smoothness, and has the technical problem of inconvenient use. According to the hinge assembly provided by the embodiments of the present disclosure, the refrigerator can be applied to embedded use, and at least the technical problems of complex structure, high cost and low door opening smoothness of the double-shaft hinge can be solved to some extent.

[0036] The technical solutions of the present disclosure will be described below in combination with FIGS. 1-17 and with reference to specific embodiments.

[0037] As shown in FIGS. 1-5, the hinge assembly 200 is provided according to the embodiments of the present disclosure.

[0038] As shown in FIG. 1, the hinge assembly 200 can be applied to the storage device 100. The main body 110 and the door body 120 of the storage device 100 can be hinged by the hinge assembly 200, so that the door body 120 can rotate relative to the main body 110.

[0039] In some embodiments, the hinge assembly 200 includes a first hinge piece 210 and a second hinge piece 220. The first hinge piece 210 and the second hinge piece 220 can be respectively mounted on the main body 110 and the door body 120.

[0040] As shown in FIGS. 3 and 4, the first hinge piece 210 is provided with at least a first guide groove 211 and a second guide groove 212. The length directions of the first guide groove 211 and the second guide groove 212 extend along different predetermined trajectories respectively, and the first guide groove 211 and the second guide groove 212 are arranged in communication with each other.

[0041] In some embodiments, the first hinge piece 210 can be provided in a block shape. The first guide groove 211 and the second guide groove 212 are both arranged on the same surface of the first hinge piece 210 and are provided in a long shape. The length directions of the guide grooves extend along the predetermined trajectories to define the guide directions of the guide grooves. The predetermined trajectories of the first guide groove 211 and the second guide groove 212 are different, thereby defining at least two guide directions.

[0042] As shown in FIG. 5, the second hinge part 220 is provided with at least a first guide shaft 221 and a second guide shaft 222 arranged in a spaced manner. At least one of the first guide shaft 221 and the second guide shaft 222 is capable of sliding in the first guide slot 211 and the second guide slot 212, so that the first hinge part 210 and the second hinge part 220 can rotate relatively along a predetermined track.

[0043] In some embodiments, the second hinge part 220 can include a seat body. The first guide shaft 221 and the second guide shaft 222 are arranged on the same side of the seat body in a spaced manner. In the case where the second hinge part 220 cooperates with the first hinge part 210, the guide shafts can extend into the guide slots and slide along the length direction of the guide slots, so that the first hinge part 210 and the second hinge part 220 are hingedly cooperated. The guide shafts can move in the guide slots along a predetermined track, so that the first hinge part 210 and the second hinge part 220 rotate relatively along the predetermined track.

[0044] Since the first guide slot 211 and the second guide slot 212 are in communication with each other, at least one of the first guide shaft 221 and the second guide shaft 222 can slide in the first guide slot 211 and the second guide slot 212. Through the design of the predetermined track of the first guide slot 211 and the second guide slot 212 and the relative position of the first guide shaft 221 and the second guide shaft 222, the guide shafts can transition from one guide slot to another guide slot to change the movement track.

[0045] It should be noted that the first hinge part 210 and the second hinge part 220 start from an initial state and rotate relatively in a positive direction, which corresponds to the door body 120 rotating from a closed state to an open state of the storage device 100. The first hinge part 210 and the second hinge part 220 can also rotate relatively in a reverse direction to return to the initial state, which corresponds to the door body 120 rotating from an open state to a closed state of the storage device 100. For the convenience of understanding and description, in the subsequent description of the movement of the guide shaft in the guide slot, the first hinge part 210 and the second hinge part 220 are taken as rotating relatively in a positive direction, that is, the door body 120 is taken as rotating from a closed state to an open state, and the subsequent description will not be repeated.

[0046] In some embodiments, the first hinge part 210 and the second hinge part 220 can be in at least one of the following first to third cooperation forms during the relative rotation.

[0047] In the first cooperation form, the first guide shaft 221 can slide in one of the first guide slot 211 or the second guide slot 212, and the second guide shaft 222 can slide in the first guide slot 211 and the second guide slot 212.

[0048] In this embodiment, the first guide shaft 221 always slides in the first guide slot 211 or the second guide slot 212 when the first hinge piece 210 and the second hinge piece 220 rotate relative to each other. The second guide shaft 222 can first slide in the first guide slot 211, then switch to the second guide slot 212 through the communication between the first guide slot 211 and the second guide slot 212 during the rotation, and then slide in the second guide slot 212. It can be understood that the second guide shaft 222 can also first slide in the second guide slot 212 and then switch to the first guide slot 211, or switch back and forth between the first guide slot 211 and the second guide slot 212, which is not limited herein.

[0049] In the second matching mode, the first guide shaft 221 can slide in the first guide slot 211 and the second guide slot 212, and the second guide shaft 222 can slide in one of the first guide slot 211 or the second guide slot 212.

[0050] In this embodiment, the second guide shaft 222 always slides in the first guide slot 211 or the second guide slot 212 when the first hinge piece 210 and the second hinge piece 220 rotate relative to each other. The first guide shaft 221 can first slide in the first guide slot 211, then switch to the second guide slot 212 through the communication between the first guide slot 211 and the second guide slot 212 during the rotation, and then slide in the second guide slot 212. It can be understood that the first guide shaft 221 can also first slide in the second guide slot 212 and then switch to the first guide slot 211, or switch back and forth between the first guide slot 211 and the second guide slot 212, which is not limited herein.

[0051] In the third matching mode, the first guide shaft 221 and the second guide slot 212 can both slide in the first guide slot 211 and the second guide slot 212.

[0052] In this embodiment, the first guide shaft 221 can switch between the first guide slot 211 and the second guide slot 212 during the sliding process when the first hinge piece 210 and the second hinge piece 220 rotate relative to each other, and the second guide shaft 222 can also switch between the first guide slot 211 and the second guide slot 212 during the sliding process, and the specific switching process is not limited.

[0053] It should be noted that, because the relative positions and directions of the guide shafts and the guide slots will change during the relative rotation of the first hinge piece 210 and the second hinge piece 220, the meaning of the guide shafts sliding in the guide slots in the present disclosure includes that the guide shafts can slide along the length direction of the guide slots, and also includes that the guide shafts can rotate relative to the guide slots.

[0054] In the related art, multiple guide shafts generally move in different guide grooves. In order to meet the opening requirement of the embedded door body, the structure is generally complex, and even needs to increase the connecting rod, driving, resetting, limiting and other mechanism assistance, which is high in cost and often not smooth in rotation.

[0055] In actual implementation, the first guide shaft 221 and the second guide shaft 222 can slide in the same guide groove or in different guide grooves, so that the design of the rotation track of the hinge assembly 200 is more flexible, and the first guide shaft 221, the second guide shaft 222, the first guide groove 211 and the second guide groove 212 are all fixedly arranged. In the relative rotation process of the first hinge part 210 and the second hinge part 220, no other structure is involved, the structure is simple and the operation is smooth, and it can also ensure that the side edge of the door body 120 installed through the hinge assembly 200 will not exceed the side wall of the main body 110 in the rotation process, so as to meet the use requirement of the embedded refrigerator.

[0056] According to some embodiments of the present disclosure, a limiting part can be arranged in the second guide groove 212. In the case that the first hinge part 210 and the second hinge part 220 are relatively rotated to 85°-95°, at least part of the second guide shaft 222 can enter the second guide groove 212 and be limited by the limiting part.

[0057] Generally, the user can meet the use requirement when the door body 120 is opened to 85°-95°. By arranging the limiting part in the second guide groove 212 and limiting the second guide shaft 222, the door body 120 can have a certain holding force when it is opened to 85°-95° and will not be automatically closed, which is convenient for the user to use. It can be understood that the limiting between the limiting part and the second guide shaft 222 can be released by further rotating the door body 120.

[0058] It can be understood that the limiting angle of the limiting part to the first hinge part 210 and the second hinge part 220 can be an angle range. In some embodiments, the limiting angle range of the limiting part to the first hinge part 210 and the second hinge part 220 can be 85°-95°, 88°-92° or other angle range between 85°-95°. The limiting angle of the limiting part to the first hinge part 210 and the second hinge part 220 can also be a certain angle. In some embodiments, the limiting angle of the limiting part to the first hinge part 210 and the second hinge part 220 can be 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 93°, 94°, 95° or other value between 85°-95°, which is not limited here.

[0059] According to the hinge assembly 200 provided by the embodiments of the present disclosure, the first guide groove 211 and the second guide groove 212 are arranged to extend along different trajectories and communicate with each other, and at least one of the first guide shaft 221 and the second guide shaft 222 can slide in the first guide groove 211 and the second guide groove 212, so that the guide shaft can slide in any guide groove during the rotation of the hinge assembly 200, thereby making the movement trajectory of the hinge assembly 200 more flexible. During the opening of the door body 120, the door body 120 can rotate along the predetermined trajectory of the hinge assembly 200. The structure is simple and low in cost, the movement trajectory is smooth, and the side edge of the door body 120 does not exceed the side wall of the main body 110 during the rotation. By arranging the limiting part in the second guide groove 212 and cooperating with the second guide shaft 222, the door body 120 can have a certain holding force in the case of 85°-95°, so that the door body cannot be automatically closed, and the user can use it conveniently.

[0060] According to some embodiments of the present disclosure, as shown in FIGS. 2-4, the projections of the first guide groove 211 and the second guide groove 212 in the depth direction thereof can be arranged at least partially not to overlap.

[0061] In some embodiments, the first guide grooves 211 communicate with each other and the projections thereof in the depth direction thereof are arranged at least partially not to overlap, so that the guide trajectories of the first guide grooves 211 and the second guide groove 212 are arranged in a branched manner on the first hinge piece 210. The two spaced first guide shafts 221 and the second guide shaft 222 are facilitated to move along different guide grooves. The movement trajectory is designed to be more flexible. The operation is smoother.

[0062] According to some embodiments of the present disclosure, as shown in FIGS. 6-18, the first guide shaft 221 and the second guide shaft 222 can simultaneously slide in the first guide groove 211, and in the case that the first guide shaft 221 is limited in the length direction of the first guide groove 211, the second guide shaft 222 can slide in the second guide groove 212.

[0063] In some embodiments, the first guide shaft 221 can only slide in the first guide groove 211. The second guide shaft 222 can slide in the first guide groove 211 and the second guide groove 212.

[0064] In some embodiments, the first guide shaft 221 and the second guide shaft 222 can slide in the first guide slot 211 simultaneously when the first hinge piece 210 and the second hinge piece 220 rotate relative to each other. When the first guide shaft 221 is limited in the length direction of the first guide slot 211, the first guide shaft 221 is difficult to displace relative to the first guide slot 211. Because the positions of the first guide shaft 221 and the second guide shaft 222 are relatively fixed, the second guide shaft 222 is also difficult to slide in the first guide slot 211, so that the second guide shaft 222 can switch to the second guide slot 212 and slide in the second guide slot 212.

[0065] In actual implementation, in the initial state of the hinge assembly 200, the first guide shaft 221 and the second guide shaft 222 are both arranged in the first guide slot 211, and the second guide shaft 222 is arranged close to the end of the first guide slot 211. The first guide shaft 221 is located in the middle section of the first guide slot 211. When the first guide shaft 221 and the second guide shaft 222 slide in the first guide slot 211 to the state where the first guide shaft 221 is limited, the first guide shaft 221 and the second guide shaft 222 are difficult to continue to slide in the length direction of the first guide slot 211, so that the second guide shaft 222 can switch to the second guide slot 212. This arrangement can make the movement trajectory of the first guide shaft 221 and the second guide shaft 222 relatively stable during the relative rotation of the first hinge piece 210 and the second hinge piece 220, the switching timing is controllable, and the stability of operation is improved.

[0066] According to some embodiments of the present disclosure, as shown in FIGS. 6-10, the first guide slot 211 can include a first slot section 211a and a second slot section 211b connected at an angle, and the second guide slot 212 can be connected with the first slot section 211a; the first guide shaft 221 and the second guide shaft 222 can simultaneously slide in the first slot section 211a; and when the first guide shaft 221 slides in the second slot section 211b, the second guide shaft 222 can slide in the second guide slot 212.

[0067] In some embodiments, the first guide slot 211 can include a first slot section 211a and a second slot section 211b connected in sequence along the length direction, and the extension directions of the first slot section 211a and the second slot section 211b are different, so that the first slot section 211a and the second slot section 211b are connected at an angle. By arranging two slot sections, the movement trajectory of the door body 120 is guided and planned during the movement of the first guide shaft 221 and the second guide shaft 222 in the first guide slot 211, so as to ensure that the side edge of the door body 120 does not exceed the plane where the side wall of the main body 110 is located. The second guide slot 212 can be in communication with the first slot section 211a.

[0068] In the case that the hinge assembly 200 is in the initial state, the first guide shaft 221 and the second guide shaft 222 are both located in the first groove segment 211a, and the second guide shaft 222 is located at one end of the first groove segment 211a away from the second groove segment 211b, and the first guide shaft 221 is located at the middle of the first groove segment 211a; in the case that the first hinge piece 210 and the second hinge piece 220 are relatively rotated, the first guide shaft 221 and the second guide shaft 222 move along the first groove segment 211a in the direction close to the second groove segment 211b; in the case that the first guide shaft 221 rotates into the second groove segment 211b and slides in the second groove segment 211b, the second guide shaft 222 can be switched to slide in the second guide groove 212.

[0069] In some embodiments, in the case that the first guide shaft 221 slides along the second groove segment 211b, the second guide shaft 222 can also continue to slide in the first groove segment 211a. Because the second groove segment 211b is arranged at an angle with the first groove segment 211a, the second hinge piece 220 can be relatively rotated at a large angle with the first hinge piece 210. In the limited space, the door body 120 is conveniently rotated to open. In the case that the first guide shaft 221 moves to one end of the second groove segment 211b away from the first groove segment 211a, the first guide shaft 221 is relatively limited and is difficult to continue to slide in the length direction of the second groove segment 211b. With the first hinge piece 210 and the second hinge piece 220 continuing to relatively rotate, the second guide shaft 222 can be switched to continue to slide in the second groove segment 211b, so as to realize increasing the relative rotation angle of the first hinge piece 210 and the second hinge piece 220.

[0070] According to some embodiments of the present disclosure, as shown in FIGS. 6-10, in the case that the first guide shaft 221 slides in the first groove segment 211a, the angle of the second hinge piece 220 relative to the first hinge piece 210 can be 0°-45°; or, in the case that the first guide shaft 221 slides in the second groove segment 211b, the angle of the second hinge piece 220 relative to the first hinge piece 210 can be 30°-95°.

[0071] And / or, in the case that the second guide shaft 222 slides in the second guide groove 212, the angle of the second hinge piece 220 relative to the first hinge piece 210 can be 85°-150°.

[0072] In some embodiments, referring to FIGS. 6 and 7, when the first guide shaft 221 slides in the first slot segment 211a, the second guide shaft 222 also slides in the first slot segment 211a. The angle of relative rotation between the second hinge member 220 and the first hinge member 210 is 0°-45°. As the first guide shaft 221 moves along the first slot segment 211a towards the second slot segment 211b, the angle of relative rotation between the second hinge member 220 and the first hinge member 210 gradually increases. In this process, the first hinge member 210 and the second hinge member 220 are displaced in the direction of the line connecting the axes of the first guide shaft 221 and the second guide shaft 222. With the second hinge member 220 as the reference, the first hinge member 210 is displaced a certain distance in the direction of the axis of the second guide shaft 222 from the axis of the first guide shaft 221 relative to the second hinge member 220, so that in this rotation process, the door body 120 can have a certain lateral displacement relative to the main body 110, so that the side edge of the door body 120 does not exceed the frame of the main body 110. Exemplarily, when the first guide shaft 221 moves to the end of the first slot segment 211a close to the second slot segment 211b, the angle of relative rotation between the first hinge member 210 and the second hinge member 220 can be 30°, 32°, 35°, 37°, 40°, 42°, 45°, or other angles between 30° and 45°, which are not limited herein.

[0073] In some embodiments, referring to FIGS. 7 and 8, when the first guide shaft 221 slides in the second slot segment 211b, the second guide shaft 222 also slides in the first slot segment 211a. The angle of relative rotation between the second hinge member 220 and the first hinge member 210 can be 30°-95°. As the first guide shaft 221 moves along the second slot segment 211b away from the first slot segment 211a, the angle of relative rotation between the first hinge member 210 and the second hinge member 220 gradually increases. In this process, the center of relative rotation between the second hinge member 220 and the first hinge member 210 is located between the first slot segment 211a and the second slot segment 211b, so that in this rotation process, the door body 120 has a large rotation angle and a small lateral displacement relative to the main body 110. Exemplarily, when the first guide shaft 221 moves to the end of the second slot segment 211b away from the first slot segment 211a, the angle of relative rotation between the first hinge member 210 and the second hinge member 220 can be 85°, 87°, 89°, 90°, 92°, 94°, 95°, or other angles between 85° and 95°, which are not limited herein.

[0074] In some embodiments, referring to FIGS. 9 and 10, the first guide shaft 221 can slide in the second slot segment 211b under the condition that the second guide shaft 222 slides in the second guide slot 212. The angle of relative rotation between the second hinge piece 220 and the first hinge piece 210 can be 85°-150°. As the second guide shaft 222 moves along the second guide slot 212 in a direction away from the first guide slot 211, the angle of relative rotation between the first hinge piece 210 and the second hinge piece 220 gradually increases, so that the door body 120 can be opened at a large angle. In some embodiments, under the condition that the second guide shaft 222 slides to the end of the second guide slot 212 away from the first guide slot 211, the angle of relative rotation between the first hinge piece 210 and the second hinge piece 220 can be 140°, 141°, 142°, 144°, 145°, 147°, 149°, 150°, or other angles between 140°-150°, which are not limited herein.

[0075] It should be noted that, in the case of a zero-embedded refrigerator, the side walls of the main body 110 and the door body 120 are very close to the wall. During the sliding of the first guide shaft 221 along the first slot segment 211a, the door body 120 is moved laterally by a certain distance, so that the front side of the door body 120 can be spaced apart from the wall when the door body 120 is rotated to 90°, so that the door body 120 can be further rotated by a certain angle to achieve large-angle opening of the door body 120 of the zero-embedded refrigerator. As shown in FIG. 9, under the installation condition of zero embedding, the second guide shaft 222 slides to the middle of the second guide slot 212 to reach the limit rotation angle. Exemplarily, the limit rotation angle can be 115°, 117°, 119°, 120°, 122°, 124°, 125°, or other angles between 115°-125°, which are not limited herein.

[0076] According to some embodiments of the present disclosure, as shown in FIGS. 2-10, the second slot segment 211b and the second guide slot 212 can be respectively located on both sides of the width direction of the first slot segment 211a.

[0077] In some embodiments, the second slot segment 211b and the second guide slot 212 can be respectively arranged on both sides of the extension direction of the first slot segment 211a, so that after the first guide shaft 221 enters the second slot segment 211b on one side of the first slot segment 211a, the second guide shaft 222 can enter the second guide slot 212 on the other side of the first slot segment 211a. The first guide shaft 221 and the second guide shaft 222 respectively move to different sides of the first slot segment 211a to increase the angle of relative rotation between the two hinge pieces while controlling the area occupied by the guide slot as much as possible.

[0078] In some embodiments, as shown in FIGS. 2-10, the first groove segment 211a and the second groove segment 211b can each be arranged in a circular arc shape. The first groove segment 211a and the second groove segment 211b can be connected by a circular arc-shaped connecting segment. The sides of the first groove segment 211a and the second groove segment 211b facing the center of the circle can be arranged opposite to each other.

[0079] In some embodiments, the projections of the first groove segment 211a and the second groove segment 211b in the depth direction are each arranged in a circular arc shape, and the projection of the connecting segment between the first groove segment 211a and the second groove segment 211b in the depth direction is also arranged in a circular arc shape, so that the first guide shaft 221 and the second guide shaft 222 slide in the first guide groove 211 with a smoother trajectory and a smoother rotation path.

[0080] In some embodiments, when the first guide shaft 221 and the second guide shaft 222 slide in the first groove segment 211a, the door body 120 can rotate around the center of the circle defined by the arc of the first groove segment 211a. In the case where the hinge assembly 200 is installed in the storage device 100, the center of the predetermined trajectory of the first groove segment 211a is located on the side of the door body 120 away from the main body 110, so that during the opening of the door body 120 from the closed position, the rotation of the door body 120 is accompanied by a displacement of the door body 120 in the lateral direction, i.e., the side edges of the door body 120 have a displacement in the direction away from the side wall of the main body 110, so that the side edges of the door body 120 do not exceed the plane of the side wall of the main body 110.

[0081] As shown in FIGS. 2-4, 6-10, the first groove segment 211a and the second groove segment 211b can be connected by a circular arc-shaped connecting segment, and the sides of the first groove segment 211a and the second groove segment 211b facing the center of the circle can be arranged opposite to each other.

[0082] By arranging a circular arc transition segment between the first groove segment 211a and the second groove segment 211b, the turning trajectory of the first guide shaft 221 when sliding to the second groove segment 211b is smoother, and the opening smoothness is improved. In some embodiments, the sides of the first groove segment 211a and the second groove segment 211b facing the center of the circle are arranged opposite to each other, so that during the movement of the first guide shaft 221 and the second guide shaft 222 in the second groove segment 211b and the first groove segment 211a, respectively, the door body 120 rotates by a large angle, and the trajectory of the center of rotation of the door body 120 defined by the fitting of the first groove segment 211a and the second groove segment 211b is located between the first groove segment 211a and the second groove segment 211b, thereby avoiding a large lateral displacement of the door body 120 during the opening to 85°-95°. As shown in FIG. 6, two trajectories of the side edges of the door body 120 during the opening are labeled as trajectory one 310 and trajectory two 320 in FIG. 6.

[0083] According to some embodiments of the present disclosure, one side of the second guide groove 212 in the width direction can be in communication with the side of the first groove segment 211a away from the second groove segment 211b. The extension trajectory of the second guide groove 212 can be in the shape of a circular arc. The center of the circular arc of the second guide groove 212 can be located at the end of the second groove segment 211b away from the first groove segment 211a.

[0084] In some embodiments, the second guide groove 212 is located at the side wall of the side away from the first groove segment 211a and is connected to the side wall of the first groove segment 211a, and the side of the second guide groove 212 close to the first groove segment 211a is open, so that the side of the second guide groove 212 is in communication with the side of the first groove segment 211a.

[0085] In some embodiments, the center of the circular arc formed by the predetermined trajectory of the second guide groove 212 is located at the end of the second groove segment 211b away from the first groove segment 211a. When the first hinge piece 210 and the second hinge piece 220 are relatively rotated to 85°-95°, the first guide shaft 221 is just active to the end of the second groove segment 211b away from the first groove segment 211a. When the door body 120 is further rotated, the first guide shaft 221 cannot be active along the length direction of the second groove segment 211b. At this time, the second groove segment 211b rotates around the first guide shaft 221, so that the second guide shaft 222 moves along the second guide groove 212.

[0086] It can be understood that the distance between the axes of the first guide shaft 221 and the second guide shaft 222 is equal to the radius of the circular arc of the predetermined trajectory of the second guide groove 212.

[0087] The hinge assembly 200 according to the embodiments of the present disclosure has a simple structure and a single and stable movement trajectory, and the rotation process is smooth and the operation is fluent, so that the user experience is better.

[0088] According to some embodiments of the present disclosure, as shown in FIGS. 11-18, the first guide groove 211 has a first end and a second end. When the hinge assembly 200 is in the initial state, the second guide shaft 222 is located at the first end of the first guide groove 211.

[0089] In some embodiments, as shown in FIG. 11, when the hinge assembly 200 is in the initial state, i.e., the door body 120 is in the closed state, the first end of the first guide groove 211 is located close to the front side and the middle part of the door body 120 relative to the second end, and the second guide shaft 222 is located at the first end of the first guide groove 211.

[0090] The first guide shaft 221 can be located on one side of the second guide shaft 222 close to the second end, and the first guide shaft 221 and the second guide shaft 222 can simultaneously slide in the first guide slot 211 towards the second end; under the condition that the first guide shaft 221 slides to the second end and is limited, the second guide shaft 222 can slide in the second guide slot 212.

[0091] In some embodiments, as shown in FIG. 11 and FIG. 12, the first guide shaft 221 can be located at the middle section of the first guide slot 211, that is, on one side of the second guide shaft 222 close to the second end. The first guide shaft 221 and the second guide shaft 222 can simultaneously slide in the first guide slot 211 towards the second end, in the process, the first hinge piece 210 and the second hinge piece 220 relatively rotate and generate a certain relative displacement in the transverse direction. The certain relative displacement can generate a certain transverse displacement of the door body 120 towards the center position, so that the door body 120 does not exceed the side wall of the main body 110 during rotation.

[0092] Under the condition that the first guide shaft 221 slides to the second end, the first guide shaft 221 is limited in the length direction of the first guide slot 211 and is difficult to continue to move along the length direction of the first guide slot 211. Continue to rotate the first hinge piece 210 and the second hinge piece 220, so that the first hinge piece 210 rotates around the first guide shaft 221, and then the second guide shaft 222 can enter the second guide slot 212 and slide in the second guide slot 212, so that the first hinge piece 210 and the second hinge piece 220 can continue to relatively rotate. In this process, the first guide shaft 221 is rotated by a large angle to achieve fast opening of the door body 120.

[0093] Under the condition that the first guide shaft 221 slides towards the first end, the second guide shaft 222 can slide in the second guide slot 212 in the forward direction or the reverse direction.

[0094] As shown in FIG. 13 and FIG. 14, under the condition that the first guide shaft 221 can slide in the first guide slot 211 in the reverse direction towards the first end, the second guide shaft 222 can continue to slide in the second guide slot 212 in the direction away from the first guide slot 211 to the end of the second guide slot 212 away from the first guide slot 211 to avoid interference.

[0095] As shown in FIG. 14-FIG. 17, the first guide shaft 221 can continue to slide in the first guide slot 211 in the reverse direction towards the first end, and then drive the second guide shaft 222 to also slide in the second guide slot 212 in the reverse direction towards the first guide slot 211, gradually exiting the second guide slot 212 and returning to the first guide slot 211. In this process, the relative rotation angle of the first hinge piece 210 and the second hinge piece 220 is further increased.

[0096] In the case that the second guide shaft 222 slides to the first guide groove 211 and the second guide shaft 222 is located at the side of the first guide shaft 221 close to the second end, the second guide shaft 222 and the first guide shaft 221 can simultaneously slide to the second end in the first guide groove 211.

[0097] In some embodiments, as shown in FIG. 17 and FIG. 18, in the case that the second guide shaft 222 reversely slides to the first guide groove 211 and the first guide shaft 221 has already slid to the side of the second guide shaft 222 close to the first end, the second guide shaft 222 and the first guide shaft 221 can simultaneously slide to the second end in the first guide groove 211. In this process, the relative rotation angle of the first hinge piece 210 and the second hinge piece 220 is further increased.

[0098] According to another embodiment of the present disclosure, another hinge assembly 200 is provided. The relative rotation angle of the first hinge piece 210 and the second hinge piece 220 is larger, and thus the opening angle of the door body 120 is larger, which can reach more than 180°. In the case of non-embedded installation, super-large angle opening can be realized, which can adapt to more use scenarios.

[0099] According to some embodiments of the present disclosure, as shown in FIG. 11-FIG. 18, in the case that the first guide shaft 221 is located at the side of the second guide shaft 222 close to the second end and slides to the second end along the first guide groove 211, the rotation angle of the second hinge piece 220 relative to the first hinge piece 210 is 0°-45°; and / or, in the case that the second guide shaft 222 slides in the second guide groove 212, the rotation angle of the second hinge piece 220 relative to the first hinge piece 210 is 45°-125°; and / or, in the case that the first guide shaft 221 slides to the first end in the first guide groove 211, the rotation angle of the second hinge piece 220 relative to the first hinge piece 210 is 45°-180°; and / or, in the case that the second guide shaft 222 is located at the side of the first guide shaft 221 close to the second end and slides to the second end along the first guide groove 211, the rotation angle of the second hinge piece 220 relative to the first hinge piece 210 is 180°-210°.

[0100] In some embodiments, referring to FIGS. 11 and 12, under the condition that the first guide shaft 221 is located at one side of the second guide shaft 222 close to the second end and moves along the first guide slot 211 toward the second end, the second guide shaft 222 is also located in the first guide slot 211 and slides toward the second end simultaneously with the first guide shaft 221. The angle of relative rotation between the second hinge piece 220 and the first hinge piece 210 is 0°-45°. As the first guide shaft 221 moves toward the second end, the angle of relative rotation between the second hinge piece 220 and the first hinge piece 210 gradually increases. During this process, the first hinge piece 210 and the second hinge piece 220 are displaced in the direction of the axis line of the first guide shaft 221 and the second guide shaft 222. With the second hinge piece 220 as the reference, the first hinge piece 210 is displaced a certain distance in the direction of the axis of the second guide shaft 222 from the axis of the first guide shaft 221, so that during this rotation process, the door body 120 can have a certain lateral displacement relative to the main body 110, so that the side edge of the door body 120 does not exceed the frame of the main body 110. Exemplarily, as shown in FIG. 12, under the condition that the first guide shaft 221 moves to the second end, the angle of relative rotation between the first hinge piece 210 and the second hinge piece 220 can be 26°, 30°, 35°, 40°, 45°, or other angles between 25°-45°, which are not limited herein.

[0101] In some embodiments, referring to FIGS. 13-15, under the condition that the second guide shaft 222 slides in the second guide slot 212, the first guide shaft 221 can first rotate at the second end, i.e., the first hinge piece 210 rotates around the first guide shaft 221. Then the first guide shaft 221 reverses its movement along the first guide slot 211 toward the first end. The angle of relative rotation between the second hinge piece 220 and the first hinge piece 210 is 45°-125°. As shown in FIG. 14, under the condition that the second guide shaft 222 slides to a certain distance from the end of the second guide slot 212 away from the first guide slot 211, and the first guide shaft 221 is spaced a certain distance from the second end, the angle of relative rotation between the first hinge piece 210 and the second hinge piece 220 is 90°. As the second guide shaft 222 continues to slide along the second guide slot 212 away from the first guide slot 211, the first guide shaft 221 moves toward the first end. Under the condition that the second guide shaft 222 slides to the end of the second guide slot 212 away from the first guide slot 211, the angle of relative rotation between the first hinge piece 210 and the second hinge piece 220 can be 115°, 117°, 119°, 120°, 122°, 124°, 125°, or other angles between 115°-125°, which are not limited herein.

[0102] In some embodiments, referring to FIGS. 16 and 17, under the condition that the first guide shaft 221 slides in the first guide slot 211 towards the first end, the second guide shaft 222 first moves along the second guide slot 212 towards the end away from the first guide slot 211, and then moves along the second guide slot 212 towards the end close to the first guide slot 211 and exits the second guide slot 212. The angle of rotation of the second hinge part 220 relative to the first hinge part 210 is 45°-180°. As the first guide shaft 221 approaches the first end, the angle of relative rotation of the first hinge part 210 and the second hinge part 220 gradually increases. In some embodiments, under the condition of non-zero embedded installation, when the first guide shaft 221 slides to the first end, the angle of relative rotation of the first hinge part 210 and the second hinge part 220 can be 175°, 177°, 179°, 180°, 182°, 184°, 185°, or other angles between 175°-185°, which are not limited herein.

[0103] In some embodiments, referring to FIGS. 17 and 18, under the condition that the second guide shaft 222 is located on the side of the first guide shaft 221 close to the second end and slides along the first guide slot 211 towards the second end, both the first guide shaft 221 and the second guide shaft 222 move along the first guide slot 211 compared with the initial state. However, the relative positions of the first guide shaft 221 and the second guide shaft 222 in the first guide slot 211 change. The angle of rotation of the second hinge part 220 relative to the first hinge part 210 is 180°-210°. As the second guide shaft 222 slides towards the second end, the angle of relative rotation of the first hinge part 210 and the second hinge part 220 increases. In the case that the second guide shaft 222 moves to the second end or the front side of the door body 120 interferes with the side wall of the main body 110, the angle of relative rotation of the first hinge part 210 and the second hinge part 220 reaches a limit. In some embodiments, the limit angle can be 200°, 202°, 204°, 206°, 208°, 210°, or other angles between 200°-210°, which are not limited herein.

[0104] According to some embodiments, as shown in FIGS. 11-18, the predetermined trajectories of the first guide slot 211 and the second guide slot 212 can both be arranged in a circular arc shape. One end of the length direction of the second guide slot 212 communicates with the side of the first guide slot 211 away from the center of the circle. The center of the circle of the second guide slot 212 can be located on the side of the second guide slot 212 towards the second end.

[0105] In some embodiments, one end of the second guide slot 212 can be connected with the middle section of the first guide slot 211, so that the predetermined trajectories of the second guide slot 212 and the first guide slot 211 form a shape similar to Y.

[0106] In some embodiments, the predetermined track of the first guide slot 211 can be arranged in a circular arc shape. In the initial state of the hinge assembly 200, the center of the circular arc of the predetermined track of the first guide slot 211 is located on the side of the door body 120 away from the main body 110, so that in the process of opening the door body 120 from the initial state to the first guide shaft 221 moving to the second end, the rotation of the door body 120 is accompanied by a displacement in the transverse direction, that is, the side of the door body 120 has a displacement in the direction close to the center of the door body 120, so that the side of the door body 120 does not exceed the plane in which the side wall of the main body 110 is located.

[0107] The center of the circular arc of the second guide slot 212 is located on the side of the second guide slot 212 toward the second end, so that the second guide shaft 222 can slide in the second guide slot 212 under the condition that the first guide shaft 221 is located on the side of the second guide slot 212 toward the second end. The second guide slot 212 is arranged on the side of the first guide slot 211 away from the center of the circular arc, so that when the second guide shaft 222 slides in the second guide slot 212, the first hinge part 210 and the second hinge part 220 can further rotate in the positive direction.

[0108] In some embodiments, the limiting part can be a protruding buckle arranged on the bottom of the second guide slot 212. The end of the second guide shaft 222 can be provided with a recess. When the second guide shaft 222 moves to the position corresponding to the protruding buckle, at least part of the protruding buckle can extend into the recess to cooperate with the recess, thereby achieving the limiting effect.

[0109] According to some embodiments of the present disclosure, as shown in FIG. 4, the limiting part can include at least two protruding parts 213 arranged on the side wall of the second guide slot 212. The two protruding parts 213 can be arranged in a spaced manner along the length direction of the second guide slot 212. When the first hinge part 210 and the second hinge part 220 rotate relative to each other to 85°-95°, the second guide shaft 222 can be located between the two protruding parts 213.

[0110] In some embodiments, the side wall of the second guide slot 212 can be provided with at least two protruding parts 213. The two protruding parts 213 are arranged on the side wall of the second guide slot 212 away from the first guide slot 211, and the two protruding parts 213 are located at the entrance of the second guide slot 212, so that when the first hinge part 210 and the second hinge part 220 rotate relative to each other to 85°-95°, the second guide shaft 222 moves between the two protruding parts 213. It can be understood that the protruding height of the protruding part 213 is greater than the cooperation gap between the second guide shaft 222 and the second guide slot 212, so as to effectively limit the movement of the second guide shaft 222.

[0111] By arranging two protruding parts 213 and spacing the two protruding parts 213, the second guide shaft 222 is limited in two directions, thereby improving the limiting effect.

[0112] In some embodiments, the convex part 213 can be provided in plurality, and the specific number is not limited herein, which can be three, four, five or more. By providing multiple convex parts 213, the door body 120 can be positioned at multiple angles, thereby improving the use experience.

[0113] According to some embodiments of the present disclosure, as shown in FIGS. 2-4, the length direction of the first guide shaft 221 and the second guide shaft 222 can extend along the depth direction of the first guide groove 211 and the second guide groove 212; the depth of the first guide groove 211 can be greater than the depth of the second guide groove 212. The length of the first guide shaft 221 can be greater than the depth of the second guide groove 212 and less than or equal to the depth of the first guide groove 211. The length of the second guide shaft 222 can be less than or equal to the depth of the second guide groove 212.

[0114] It should be noted that the length direction of the first guide shaft 221 and the second guide shaft 222 can be arranged in parallel, and the depth direction of the two guide grooves can be arranged in parallel, so that the first guide shaft 221 and the second guide shaft 222 can move in the same guide groove, and a single guide shaft can be in sliding fit with different guide grooves.

[0115] In some embodiments, the depths of the first guide groove 211 and the second guide groove 212 can be arranged differently. The lengths of the first guide shaft 221 and the second guide shaft 222 can be arranged differently. The depth of the first guide groove 211 and the length of the first guide shaft 221 are greater than the depth of the second guide groove 212, and the length of the first guide shaft 221 is less than or equal to the depth of the first guide groove 211, so that in the rotation process of the hinge assembly 200, the first guide shaft 221 does not interfere with the groove bottom of the first guide groove 211, and the first guide shaft 221 does not enter the second guide groove 212.

[0116] The length of the second guide shaft 222 is less than or equal to the depth of the second guide groove 212, so that the length of the second guide shaft 222 is less than or equal to the depth of the first guide groove 211, so that the second guide shaft 222 can be in sliding fit with the first guide groove 211 and can also enter the second guide groove 212 and be in sliding fit with the second guide groove 212.

[0117] By limiting the first guide shaft 221 to be in sliding fit with the first guide groove 211, the rotation trajectory of the hinge assembly 200 is constrained to a certain extent, so that the movement trajectory of the hinge assembly 200 in the opening process is more stable, thereby improving the use convenience.

[0118] According to some embodiments of the present disclosure, as shown in FIG. 2, the end of the guide shaft can be arranged in interval with the groove bottom of the guide groove.

[0119] In some embodiments, the end of the guide shaft, i.e. the end of the guide shaft towards the bottom of the guide groove, is designed to be spaced from the bottom of the guide groove to reduce interference and frictional loss during relative rotation of the first hinge member 210 and the second hinge member 220, and to improve the durability of the assembly.

[0120] In some embodiments, the length of the first guide shaft 221 can be less than the depth of the first guide groove 211, so that the end of the first guide shaft 221 is spaced from the bottom of the guide groove; the length of the second guide shaft 222 can be less than the depth of the second guide groove 212, so that the end of the second guide shaft 222 is spaced from the bottom of the guide groove.

[0121] According to some embodiments of the present disclosure, as shown in FIGS. 5-18, the radial dimension of the first guide shaft 221 and the second guide shaft 222 can be the same.

[0122] In some embodiments, the width of the guide groove can be uniform in the length direction thereof. By setting the radial dimension of the first guide shaft 221 and the second guide shaft 222 to be the same, the stability of the first guide shaft 221 and the second guide shaft 222 when moving in the same guide groove, and the stability of relative rotation of the first hinge member 210 and the second hinge member 220 can be improved.

[0123] In some embodiments, the width of the first guide groove 211 and the second guide groove 212 can be the same, so that the guide shafts can be slidably fitted with different guide grooves, and the stability of the relative rotation trajectory of the first hinge member 210 and the second hinge member 220 when the guide grooves move in different guide grooves can be ensured.

[0124] It can be understood that the guide shaft and the guide groove can be clearance-fitted to reduce the frictional resistance between the guide shaft and the inner wall of the guide groove, and to improve the smoothness of the hinge assembly 200 during rotation.

[0125] In some embodiments, the radial dimension of the guide shafts can be different. For example, the width of the second guide groove 212 can be less than the width of the first guide groove 211. The radial dimension of the first guide shaft 221 can be greater than the width of the second guide groove 212 and less than the width of the first guide groove 211. The radial dimension of the second guide shaft 222 can be less than the width of the second guide groove 212. Thus, when the hinge assembly 200 is rotated, the second guide shaft 222 can move in the first guide groove 211 or enter the second guide groove 212, and the first guide shaft 221 can only move in the first guide groove 211, thereby playing a role in restricting the movement trajectory to a certain extent.

[0126] In some embodiments, as shown in FIGS. 5-18, the cross section of the guide shaft in the length direction thereof can be circularly arranged to facilitate the sliding and rotating of the guide shaft in the guide groove, the smooth surface of the guide shaft is not easy to interfere with the inner wall of the guide groove and reduce the frictional resistance, and the structural strength is high.

[0127] In some embodiments, the end of the first guide groove 211 and the second guide groove 212 in the depth direction thereof is circularly arranged to facilitate the cooperation with the guide shaft and facilitate the rotating around the guide shaft.

[0128] Based on the same concept, as shown in FIG. 1, the present disclosure also provides a storage device 100. The storage device 100 comprises a main body 110, a door body 120 and a hinge assembly 200. The front side of the main body 110 has an opening. The door body 120 is hingedly connected to the front side of the main body 110 through the hinge assembly 200, so that the door body 120 can open and close the opening of the main body 110.

[0129] In some embodiments, one of the first hinge part 210 and the second hinge part 220 is mounted on the main body 110, and the other is mounted on the door body 120. During the opening of the door body 120 to 90°, the side edge of the door body 120 does not exceed the plane in which the side wall of the main body 110 is located.

[0130] It should be noted that the upper and lower ends of the door body 120 can be connected to the main body 110 through the hinge assembly 200, thereby improving the connection strength and the stability of rotation. It should be further noted that the mounting positions of the first hinge part 210 and the second hinge part 220 on the main body 110 and the door body 120 can be transposed, and both can achieve the purpose of the present disclosure.

[0131] For example, the first hinge part 210 can be mounted on the door body 120, and the second hinge part 220 can be mounted on the main body 110. Referring to FIGS. 1, 2 and 6, in some embodiments, the first hinge part 210 in the form of a block is embedded in the door body 120. One end of the seat body of the second hinge part 220 is fixedly connected to the main body 110, and the other end protrudes from the front side of the main body 110. The first guide shaft 221 and the second guide shaft 222 of the second hinge part 220 are mounted on the part of the seat body protruding from the main body 110.

[0132] In some other embodiments, the first hinge part 210 can be mounted on the main body 110. The second hinge part 220 can be mounted on the door body 120.

[0133] According to the storage device 100 provided by the application, by using the hinge assembly 200 as described above, the structure is simple and the cost is low, and the opening process is smooth. During the opening of the door body 120 to 90°, the side edge of the door body 120 does not exceed the plane in which the side wall of the main body 110 is located, thereby meeting the embedded mounting requirement.

[0134] According to some embodiments of the present disclosure, as shown in FIGS. 2-18, when the door body 120 is in the closed position, the first guide shaft 221 can be located on the side of the second guide shaft 222 close to the main body 110, and the first guide slot 211 can be located on the side of the second guide slot 212 away from the main body 110.

[0135] In some embodiments, when the door body 120 is in the closed position, i.e., the hinge assembly 200 is in the initial state, the first guide shaft 221 can be located on the side of the second guide shaft 222 close to the main body 110, and the first guide shaft 221 can also be located on the side of the second guide shaft 222 away from the center of the door body 120, and the first guide slot 211 can be located on the side of the second guide slot 212 away from the main body 110. This can make the first hinge piece 210 and the second hinge piece 220 rotate along a predetermined trajectory when they are relatively rotated. The door body 120 has a displacement in the direction close to the center of the door body 120 during rotation, so that the side edge of the door body 120 does not exceed the side wall of the main body 110, satisfying the zero-embedded installation of the refrigerator.

[0136] According to some embodiments of the present disclosure, the storage device 100 can be at least one of a refrigerator, a freezer, an oven, and a microwave oven.

[0137] According to the hinge assembly of the embodiments of the present disclosure, the first guide slot and the second guide slot are arranged to extend along different trajectories and communicate with each other. At least one of the first guide shaft and the second guide shaft can slide in the first guide slot and the second guide slot, so that the guide shaft can slide in any guide slot during rotation of the hinge assembly. Thus, the movement trajectory of the hinge assembly is more flexible, and the door body can rotate along a predetermined trajectory of the hinge assembly during opening. The structure is simple and low in cost. The movement trajectory is smooth. The side edge of the door body does not exceed the side wall of the main body during rotation. By arranging the limiting portion in the second guide slot to limit the second guide shaft, the door body can have a certain holding force when it is at 85°-95°, and the door body will not automatically close, which is convenient for users to use.

[0138] According to the storage device of the embodiments of the present disclosure, by using the hinge assembly as described above, the structure is simple and low in cost, and the opening process is smooth. During opening of the door body to 90°, the side edge of the door body does not exceed the plane in which the side wall of the main body is located, satisfying the embedded installation requirement.

[0139] In some other embodiments, the display cabinet, the medicine storage cabinet, the cabinet, the wine cabinet, the wardrobe, and other household appliances or furniture are not particularly limited here.
