Description

Technical Field

[0001] This application belongs to the field of refrigeration technology, and in particular relates to a hinge assembly and a storage device. Background Technology

[0002] In related technologies, the refrigerator industry typically uses a hinge combining dual axes and guide grooves for refrigerator doors designed for embedding. This type of hinge minimizes the amount by which the front edge of the door extends beyond the side of the main body during the door's rotation and opening process. This results in a small, aesthetically pleasing gap when the product is embedded into the cabinet, while also allowing for easy opening of the refrigerator door. However, dual-axis hinges in this technology are structurally complex, costly, and have low smoothness when opening. Summary of the Invention

[0003] This application aims to at least partially solve the technical problems of complex structure, high cost, and low door opening smoothness of dual-axis hinges. To this end, this application provides a hinge assembly and a storage device.

[0004] In a first aspect, an embodiment of this application provides a hinge assembly, comprising:

[0005] The first hinge component has at least a first guide groove and a second guide groove. The length directions of the first guide groove and the second guide groove extend along different predetermined trajectories, and the first guide groove and the second guide groove are connected to each other.

[0006] The second hinge component is provided with at least a first guide shaft and a second guide shaft arranged at intervals. At least one of the first guide shaft and the second guide shaft can slide within the first guide groove and the second guide groove, so that the first hinge component and the second hinge component can rotate relative to each other along a predetermined trajectory.

[0007] The second guide groove is provided with a limiting part. When the first hinge and the second hinge rotate relative to each other to 85°-95°, at least a portion of the second guide shaft enters the second guide groove and cooperates with the limiting part to limit it.

[0008] According to the hinge assembly of the present application embodiment, a first guide groove and a second guide groove are provided, which extend along different trajectories and are interconnected. At least one of the first guide shaft and the second guide shaft can slide within the first guide groove and the second guide groove, so that the guide shaft can slide within either guide groove during the rotation of the hinge assembly. This makes the movement trajectory of the hinge assembly more flexible, and the door can rotate along a predetermined trajectory during the opening process. The structure is simple and low-cost, the movement trajectory is smooth, and the side of the door will not exceed the side wall of the main body during the rotation. By setting a limiting part in the second guide groove to cooperate with the second guide shaft for limiting, the door can have a certain holding force at 85°-95°, and will not close automatically, which is convenient for users.

[0009] According to one embodiment of this application, the first guide shaft and the second guide shaft can slide simultaneously in the first guide groove, and when the first guide shaft is at its upper limit in the length direction of the first guide groove, the second guide shaft can slide in the second guide groove.

[0015] When the second guide shaft slides within the second guide groove, the second hinge component rotates at an angle of 85°-150° relative to the first hinge component.

[0016] According to one embodiment of this application, the second groove segment and the second guide groove are located on both sides of the width direction of the first groove segment.

[0017] According to one embodiment of this application, the extension trajectories of the first groove segment and the second groove segment are both arranged in an arc shape, and an arc-shaped connecting segment is provided between the first groove segment and the second groove segment. The sides of the first groove segment and the second groove segment facing their own center are arranged opposite each other.

[0018] According to one embodiment of this application, one side of the second guide groove in the width direction is connected to the side of the first groove segment away from the second groove segment, the extension trajectory of the second guide groove is arranged in an arc shape, and the center of the second guide groove is located at the end of the second groove segment away from the first groove segment.

[0019] According to one embodiment of this application, the first guide groove has a first end and a second end, and when the hinge assembly is in the initial state, the second guide shaft is located at the first end of the first guide groove;

[0020] The first guide shaft is located on the side of the second guide shaft near the second end, and the first guide shaft and the second guide shaft can slide simultaneously towards the second end within the first guide groove;

[0021] Under the condition that the first guide shaft slides to the second end and is limited, the second guide shaft can slide within the second guide groove;

[0022] Under the condition that the first guide shaft slides along the first end, the second guide shaft can slide in the second guide groove in the forward or reverse direction;

[0023] When the second guide shaft slides into the first guide groove and the second guide shaft is located on the side of the first guide shaft closer to the second end, the second guide shaft and the first guide shaft can slide simultaneously into the first guide groove toward the second end.

[0024] According to one embodiment of this application, when the first guide shaft is located on the side of the second guide shaft near the second end and slides along the first guide groove toward the second end, the second hinge member rotates relative to the first hinge member by an angle of 0°-45°; and / or,

[0025] With the second guide shaft sliding within the second guide groove, the second hinge component rotates relative to the first hinge component by an angle of 45°-125°; and / or,

[0026] With the first guide shaft sliding towards the first end within the first guide groove, the second hinge member rotates relative to the first hinge member by an angle of 45°-180°; and / or,

[0027] With the second guide shaft located on the side of the first guide shaft near the second end and sliding along the first guide groove toward the second end, the second hinge member rotates at an angle of 180°-210° relative to the first hinge member.

[0060] In related technologies, the hinge structure of refrigerator doors used for embedded applications is complex and costly, and the opening smoothness is low, resulting in inconvenience in use. This application provides a hinge assembly that can be applied to embedded refrigerators, and can at least partially solve the technical problems of complex structure, high cost, and low opening smoothness of dual-axis hinges.

[0061] The following is in conjunction with the appendix Figure 1-17 This application is described with reference to specific embodiments:

[0062] like Figure 1-5 As shown, this application embodiment provides a hinge assembly 200.

[0063] refer to Figure 1 The hinge assembly 200 can be applied to the storage device 100. The main body 110 and the door 120 of the storage device 100 can be hinged together by the hinge assembly 200, so that the door 120 can rotate relative to the main body 110.

[0064] In this embodiment, the hinge assembly 200 includes a first hinge component 210 and a second hinge component 220, wherein the first hinge component 210 and the second hinge component 220 can be respectively installed on the main body 110 and the door body 120.

[0065] like Figure 3 and Figure 4As shown, the first hinge component 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, and the first guide groove 211 and the second guide groove 212 are interconnected.

[0066] In this embodiment, the first hinge member 210 can be block-shaped. The first guide groove 211 and the second guide groove 212 are both provided on the same surface of the first hinge member 210 and are elongated. The length direction of the guide groove extends along a predetermined trajectory to define the guiding direction of the guide groove. The predetermined trajectories of the first guide groove 211 and the second guide groove 212 are different, thereby defining at least two guiding directions.

[0067] like Figure 5 As shown, the second hinge member 220 is provided with at least a first guide shaft 221 and a second guide shaft 222 arranged at intervals. 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 first hinge member 210 and the second hinge member 220 can rotate relative to each other along a predetermined trajectory.

[0068] In this embodiment, the second hinge member 220 may include a base, and the first guide shaft 221 and the second guide shaft 222 are disposed on the same side of the base and spaced apart. When the second hinge member 220 cooperates with the first hinge member 210, the guide shaft can extend into the guide groove and slide along the length direction of the guide groove, thereby enabling the first hinge member 210 and the second hinge member 220 to achieve hinged cooperation. The guide shaft moves along a predetermined trajectory in the guide groove so that the first hinge member 210 and the second hinge member 220 rotate relative to each other according to the predetermined trajectory.

[0069] Because the first guide groove 211 and the second guide groove 212 are interconnected, at least one of the first guide shaft 221 and the second guide shaft 222 can slide within the first guide groove 211 and the second guide groove 212. By designing the predetermined trajectory of the first guide groove 211 and the second guide groove 212 and the relative position of the first guide shaft 221 and the second guide shaft 222, the guide shaft can transition from one guide groove to another, thereby changing the motion trajectory.

[0070] It should be noted that the first hinge 210 and the second hinge 220 rotate relative to each other from the initial state in a forward direction, which corresponds to the door 120 rotating from closed to open in the storage device 100. The first hinge 210 and the second hinge can also rotate relative to each other in the opposite direction to return to the initial state, which corresponds to the door 120 rotating from open to closed in the storage device 100. For ease of understanding and explanation, in the subsequent description of the movement of the guide shaft in the guide groove, the relative forward rotation of the first hinge 210 and the second hinge 220 shall be taken as the reference, that is, the door 120 rotating from closed to open. This will not be elaborated further.

[0071] The first hinge member 210 and the second hinge member 220 can have at least one of the following engagement forms during relative rotation:

[0072] Firstly, the first guide shaft 221 can slide within one of the first guide groove 211 or the second guide groove 212, and the second guide shaft 222 can slide within the first guide groove 211 and the second guide groove 212.

[0073] In this embodiment, when the first hinge member 210 and the second hinge member 220 rotate relative to each other, the first guide shaft 221 always slides within the first guide groove 211 or the second guide groove 212. The second guide shaft 222 can first slide within the first guide groove 211, and during rotation, it can switch to the second guide groove 212 through the connection between the first guide groove 211 and the second guide groove 212, and slide within the second guide groove 212. It can be understood that the second guide shaft 222 can also first slide within the second guide groove 212 and then switch to the first guide groove 211, and can also switch back and forth between the first guide groove 211 and the second guide groove 212. This is not limited here.

[0074] Secondly, the first guide shaft 221 can slide within the first guide groove 211 and the second guide groove 212, and the second guide shaft 222 can slide within either the first guide groove 211 or the second guide groove 212.

[0075] In this embodiment, when the first hinge member 210 and the second hinge member 220 rotate relative to each other, the second guide shaft 222 always slides within the first guide groove 211 or the second guide groove 212. The first guide shaft 221 can first slide within the first guide groove 211, and during rotation, it can switch to the second guide groove 212 through the connection between the first guide groove 211 and the second guide groove 212, and slide within the second guide groove 212. It can be understood that the first guide shaft 221 can also first slide within the second guide groove 212 and then switch to the first guide groove 211, and can also switch back and forth between the first guide groove 211 and the second guide groove 212. This is not limited here.

[0076] Third, both the first guide shaft 221 and the second guide groove 212 can slide within the first guide groove 211 and the second guide groove 212.

[0077] In this embodiment, when the first hinge member 210 and the second hinge member 220 rotate relative to each other, the first guide shaft 221 can switch between the first guide groove 211 and the second guide groove 212 during the sliding process, and the second guide shaft 222 can also switch between the first guide groove 211 and the second guide groove 212 during the sliding process. The specific switching process is not limited.

[0078] It should be noted that, since the relative position and direction of the guide shaft and the guide groove will change during the relative rotation of the first hinge member 210 and the second hinge member 220, the meaning of the guide shaft sliding in the guide groove in this application includes both the guide shaft sliding along the length direction of the guide groove and the guide shaft rotating relative to the guide groove.

[0079] In related technologies, multiple guide shafts typically move within different guide slots. To meet the opening requirements of embedded door installations, the structure is generally quite complex, and may even require the addition of linkages, drives, reset mechanisms, limiters, and other auxiliary mechanisms. This results in high costs and often uneven rotation.

[0080] 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, making the design of the rotation trajectory of the hinge assembly 200 more flexible. The first guide shaft 221, the second guide shaft 222, the first guide groove 211 and the second guide groove 212 can all be fixed. No other structure is involved in the relative rotation of the first hinge component 210 and the second hinge component 220. The structure is simple and the operation is smooth. It can also ensure that the side of the door 120 installed through the hinge assembly 200 will not exceed the side wall of the main body 110 during rotation, which meets the usage requirements of the built-in refrigerator.

[0081] According to some embodiments of this application, a limiting part may be provided in the second guide groove 212. When the first hinge member 210 and the second hinge member 220 rotate relative to each other to 85°-95°, at least a portion of the second guide shaft 222 may enter the second guide groove 212 and cooperate with the limiting part for limiting.

[0082] For general users, the refrigerator door 120 is sufficient when opened to 85°-95°. A limiting part within the second guide groove 212, in conjunction with the second guide shaft 222, ensures the door 120 maintains a certain holding force at this 85°-95° ​​angle, preventing it from closing automatically and facilitating user operation. It is understandable that further rotation of the door 120 will release the limiting part from the second guide shaft 222.

[0083] It is understood that the limiting angle of the limiting part on the first hinge member 210 and the second hinge member 220 can be an angle range. For example, the limiting angle range of the limiting part on the first hinge member 210 and the second hinge member 220 can be 85°-95°, 88°-92°, or other angle ranges between 85°-95°. The limiting angle of the limiting part on the first hinge member 210 and the second hinge member 220 can also be a fixed angle. For example, the limiting angle of the limiting part on the first hinge member 210 and the second hinge member 220 can be 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 93°, 94°, 95°, or other values ​​between 85°-95°, without specific limitation here.

[0084] According to the hinge assembly 200 provided in the embodiments of this application, a first guide groove 211 and a second guide groove 212 are provided, which extend along different trajectories and are interconnected. At least one of the first guide shaft 221 and the second guide shaft 222 can slide within the first guide groove 211 and the second guide groove 212, so that the guide shaft of the hinge assembly 200 can slide within either guide groove during rotation. This makes the movement trajectory of the hinge assembly 200 more flexible, and it can rotate along a predetermined trajectory of the hinge assembly 200 during the opening of the door 120. The structure is simple and low-cost, the movement trajectory is smooth, and the side of the door 120 will not exceed the side wall of the main body 110 during rotation. By setting a limiting part in the second guide groove 212 to cooperate with the second guide shaft 222 for limiting, the door 120 can have a certain holding force at 85°-95°, and will not close automatically, which is convenient for users.

[0085] According to some embodiments of this application, such as Figures 2-4 As shown, the projections of the first guide groove 211 and the second guide groove 212 in their depth direction may at least partially not overlap.

[0086] In this embodiment, the first guide grooves 211 are interconnected and their projections in the depth direction are at least partially non-overlapping, so that the guide trajectories of the first guide grooves 211 and the second guide grooves 212 are branched on the first hinge member 210, which facilitates the movement of the two spaced first guide shafts 221 and the second guide shafts 222 along different guide grooves, making the trajectory design more flexible and the operation smoother.

[0087] According to some embodiments of this application, such as Figures 6-18 As shown, the first guide shaft 221 and the second guide shaft 222 can slide simultaneously in the first guide groove 211, and when the first guide shaft 221 is at its upper limit in the length direction of the first guide groove 211, the second guide shaft 222 can slide in the second guide groove 212.

[0088] In this embodiment, the first guide shaft 221 can slide only within the first guide groove 211, and the second guide shaft 222 can slide within the first guide groove 211 and the second guide groove 212.

[0089] When the first hinge member 210 and the second hinge member 220 rotate relative to each other, the first guide shaft 221 and the second guide shaft 222 can slide simultaneously in the first guide groove 211. When the first guide shaft 221 is at its upper limit in the length direction of the first guide groove 211, the first guide shaft 221 is difficult to move relative to the first guide groove 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 groove 211. Thus, the second guide shaft 222 can switch to the second guide groove 212 and slide in the second guide groove 212.

[0090] In actual operation, in the initial state of the hinge assembly 200, both the first guide shaft 221 and the second guide shaft 222 are located within the first guide groove 211, with the second guide shaft 222 positioned near the end of the first guide groove 211 and the first guide shaft 221 located in the middle section of the first guide groove 211. As the first guide shaft 221 and the second guide shaft 222 slide within the first guide groove 211 to the limit position of the first guide shaft 221, it becomes difficult for the first guide shaft 221 and the second guide shaft 222 to continue sliding along the length of the first guide groove 211. Thus, the second guide shaft 222 can switch to the second guide groove 212. This arrangement ensures that the movement trajectories of the first guide shaft 221 and the second guide shaft 222 are relatively stable during the relative rotation of the first hinge member 210 and the second hinge member 220, providing strong controllability of the switching timing and improving operational stability.

[0091] According to some embodiments of this application, such as Figures 6-10 As shown, the first guide groove 211 may include a first groove segment 211a and a second groove segment 211b connected at an angle, and the second guide groove 212 may be connected to the first groove segment 211a; the first guide shaft 221 and the second guide shaft 222 may slide simultaneously in the first groove segment 211a; under the condition that the first guide shaft 221 slides in the second groove segment 211b, the second guide shaft 222 may slide in the second guide groove 212.

[0092] In this embodiment, the first guide groove 211 may include a first groove segment 211a and a second groove segment 211b connected sequentially along the length direction, and the first groove segment 211a and the second groove segment 211b extend in different directions so that the first groove segment 211a and the second groove segment 211b are connected at an angle. By setting two groove segments, the first guide shaft 221 and the second guide shaft 222 can guide the movement trajectory of the door body 120 during the movement of the first guide groove 211, so as to ensure that the side of the door body 120 does not exceed the plane where the side wall of the main body 110 is located. The second guide groove 212 can be connected to the first groove segment 211a.

[0093] When the hinge assembly 200 is in its initial state, both the first guide shaft 221 and the second guide shaft 222 are located within the first groove segment 211a, with the second guide shaft 222 located at the end of the first groove segment 211a away from the second groove segment 211b, and the first guide shaft 221 located in the middle section of the first groove segment 211a. When the first hinge member 210 and the second hinge member 220 rotate relative to each other, the first guide shaft 221 and the second guide shaft 222 move along the first groove segment 211a toward the second groove segment 211b. When the first guide shaft 221 rotates into the second groove segment 211b and slides within the second groove segment 211b, the second guide shaft 222 can switch to slide within the second guide groove 212.

[0094] When the first guide shaft 221 slides along the second groove 211b, the second guide shaft 222 can also continue to slide within the first groove 211a. Because the second groove 211b and the first groove 211a are set at an angle, the second hinge member 220 can rotate at a large angle relative to the first hinge member 210, making it convenient for the door 120 to rotate and open within a limited space. When the first guide shaft 221 moves to the end of the second groove 211b away from the first groove 211a, the first guide shaft 221 is relatively limited and it is difficult to continue sliding in the length direction of the second groove 211b. As the first hinge member 210 and the second hinge member 220 continue to rotate relative to each other, the second guide shaft 222 can switch to continue sliding within the second groove 211b, thereby increasing the relative rotation angle between the first hinge member 210 and the second hinge member 220.

[0095] According to some embodiments of this application, such as Figures 6-10 As shown, under the condition that the first guide shaft 221 slides in the first groove 211a, the rotation angle of the second hinge member 220 relative to the first hinge member 210 can be 0°-45°; or, under the condition that the first guide shaft 221 slides in the second groove 211b, the rotation angle of the second hinge member 220 relative to the first hinge member 210 can be 30°-95°.

[0096] And / or, under the condition that the second guide shaft 222 slides within the second guide groove 212, the angle of rotation of the second hinge member 220 relative to the first hinge member 210 can be 85°-150°.

[0097] In this embodiment, reference Figure 6 and Figure 7 With the first guide shaft 221 sliding within the first groove 211a, the second guide shaft 222 also slides within the first groove 211a. The rotation angle of the second hinge member 220 relative to the first hinge member 210 is 0°-45°. As the first guide shaft 221 moves along the first groove 211a towards the second groove 211b, the relative rotation angle between the second hinge member 220 and the first hinge member 210 gradually increases. During this process, the first hinge member 210 and the second hinge member 220 undergo a certain displacement along the line connecting the axes of the first guide shaft 221 and the second guide shaft 222. Taking the second hinge member 220 as a reference, the first hinge member 210 displaces a certain distance relative to the axis of the second hinge member 220 from the axis of the first guide shaft 221 towards the axis of the second guide shaft 222. This ensures that during this rotation, the door body 120 can have a certain lateral displacement relative to the main body 110, so that the side of the door body 120 does not exceed the frame of the main body 110. For example, when the first guide shaft 221 moves to one end of the first groove segment 211a near the second groove 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 here.

[0098] In this embodiment, reference Figure 7 and Figure 8 With the first guide shaft 221 sliding within the second groove 211b, the second guide shaft 222 can also slide within the first groove 211a. The relative rotation angle between the second hinge member 220 and the first hinge member 210 can be 30°-95°. As the first guide shaft 221 moves away from the first groove 211a along the second groove 211b, the relative rotation angle between the first hinge member 210 and the second hinge member 220 gradually increases. During this process, the relative rotation center of the second hinge member 220 and the first hinge member 210 is located between the first groove 211a and the second groove 211b, resulting in a large rotation angle for the door body 120 and a small lateral displacement relative to the main body 110 during this rotation. For example, when the first guide shaft 221 is moved to the end of the second groove segment 211b away from the first groove 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 here.

[0099] In this embodiment, reference Figure 9 and Figure 10 With the second guide shaft 222 sliding within the second guide groove 212, the first guide shaft 221 can slide within the second groove segment 211b. The rotation angle of the second hinge member 220 relative to the first hinge member 210 can be 85°-150°. As the second guide shaft 222 moves along the second guide groove 212 away from the first guide groove 211, the relative rotation angle of the first hinge member 210 and the second hinge member 220 gradually increases, allowing the door 120 to open at a large angle. For example, when the second guide shaft 222 slides to the end of the second guide groove 212 away from the first guide groove 211, the relative rotation angle of the first hinge member 210 and the second hinge member 220 can be 140°, 141°, 142°, 144°, 145°, 147°, 149°, 150°, or other angles between 140° and 150°, which are not limited here.

[0100] It should be noted that in the case of a zero-embedded refrigerator, the gap between the side walls of the main body 110 and the door 120 and the wall is extremely small. During the sliding of the first guide shaft 221 along the first groove segment 211a, the door 120 moves laterally a certain distance. This allows the door 120 to rotate to 90°, while maintaining a certain gap between its front side and the wall. This allows the door 120 to rotate further, enabling the zero-embedded refrigerator door 120 to open at a large angle. Figure 9 As shown, under zero-embedded installation conditions, the second guide shaft 222 slides to the middle section of the second guide groove 212 to reach the limit rotation angle. For example, the limit rotation angle can be 115°, 117°, 119°, 120°, 122°, 124°, 125° or other angles between 115° and 125°, which are not limited here.

[0101] According to some embodiments of this application, such as Figures 2-10 As shown, the second groove segment 211b and the second guide groove 212 can be located on both sides of the width direction of the first groove segment 211a, respectively.

[0102] In this embodiment, the second groove segment 211b and the second guide groove 212 can be respectively arranged on both sides of the extension direction of the first groove segment 211a, so that after the first guide shaft 221 enters the second groove segment 211b on the side of the first groove segment 211a, the second guide shaft 222 can enter the second guide groove 212 on the other side of the first groove segment 211a. The first guide shaft 221 and the second guide shaft 222 move to different sides of the first groove segment 211a, so as to increase the angle of relative rotation of the two hinge members while controlling the area occupied by the guide groove as much as possible.

[0103] According to some embodiments of this application, such as Figures 2-10 As shown, the extension trajectories of the first groove segment 211a and the second groove segment 211b can both be arranged in an arc shape. An arc-shaped connecting segment can be provided between the first groove segment 211a and the second groove segment 211b. The sides of the first groove segment 211a and the second groove segment 211b facing their own center can be arranged opposite each other.

[0104] In this embodiment, the projections of the first groove segment 211a and the second groove segment 211b in the depth direction are both arc-shaped, 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 arc-shaped, so that the first guide shaft 221 and the second guide shaft 222 slide more smoothly in the first guide groove 211 and the rotation path is smoother.

[0105] In this embodiment, when both the first guide shaft 221 and the second guide shaft 222 slide within the first groove 211a, the door 120 can rotate around the center defined by the arc of the first groove 211a. When the hinge assembly 200 is installed in the storage device 100, the center of the predetermined trajectory of the first groove 211a is located on the side of the door 120 away from the main body 110. This ensures that during the opening process from the closed position, the rotation of the door 120 is accompanied by a lateral displacement along the door 120, meaning the side of the door 120 has a displacement away from the side wall of the main body 110, thus preventing the side of the door 120 from exceeding the plane containing the side wall of the main body 110.

[0106] like Figures 2-4 , Figures 6-10 As shown, an arc-shaped connecting section can be provided between the first groove segment 211a and the second groove segment 211b, and the sides of the first groove segment 211a and the second groove segment 211b facing their own center can be arranged opposite each other.

[0107] By setting an arc transition section between the first groove segment 211a and the second groove segment 211b, the first guide shaft 221 slides to the second groove segment 211b, resulting in a smoother turning trajectory and improved opening smoothness. Specifically, the first groove segment 211a and the second groove segment 211b are positioned opposite each other on their own center sides. This ensures 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 undergoes a large-angle rotation. Furthermore, the trajectory of the rotation center of the door body 120, defined by the fitting of the first groove segment 211a and the second groove segment 211b, lies between the first groove segment 211a and the second groove segment 211b. This prevents large lateral displacement of the door body 120 during the opening process to 85°-95°. (Refer to...) Figure 6 , Figure 6The two sides of the door 120 marked with trajectory 310 and trajectory 320 during the opening process.

[0108] According to some embodiments of this application, one side of the second guide groove 212 in the width direction can be connected to 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 arranged in an arc shape, and the center 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.

[0109] In this embodiment, the side wall of the second guide groove 212 located away from the first groove segment 211a 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 connected to the side of the first groove segment 211a.

[0110] In this embodiment, the center of the 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 member 210 and the second hinge member 220 rotate relative to each other to 85°-95°, the first guide shaft 221 just moves 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 and the second groove segment 211b cannot move 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, thereby causing the second guide shaft 222 to move along the second guide groove 212.

[0111] It is understandable 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 arc of the predetermined trajectory of the second guide groove 212.

[0112] The hinge assembly 200 according to the embodiments of this application has a simple structure, a single and stable motion trajectory, a smooth rotation process, and a better user experience.

[0113] According to some embodiments of this application, such as Figures 11-18 As shown, 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.

[0114] In this embodiment, such as Figure 11 As shown, when the hinge assembly 200 is in the initial state, that is, when the door 120 is in the closed state, the first end of the first guide groove 211 is located near the front and middle of the door 120 relative to the second end, and the second guide shaft 222 is located at the first end of the first guide groove 211.

[0115] The first guide shaft 221 can be located on the side of the second guide shaft 222 near the second end. The first guide shaft 221 and the second guide shaft 222 can slide simultaneously in the first guide groove 211 toward 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 groove 212.

[0116] In this embodiment, such as Figure 11 and Figure 12 As shown, the first guide shaft 221 can be located in the middle section of the first guide groove 211, that is, on the side of the second guide shaft 222 near the second end. The first guide shaft 221 and the second guide shaft 222 can slide towards the second end simultaneously in the first guide groove 211. During this process, the first hinge member 210 and the second hinge member 220 rotate relative to each other and generate a certain relative displacement in the lateral direction. Specifically, the door body 120 generates a certain lateral displacement towards the center position, so that the edge line of the door body 120 will not exceed the side wall of the main body 110 during the rotation process.

[0117] When the first guide shaft 221 slides to the second end, the first guide shaft 221 is at its upper limit in the length direction of the first guide groove 211, making it difficult to continue moving along the length direction of the first guide groove 211. Continuing to rotate the first hinge member 210 and the second hinge member 220 allows the first hinge member 210 to rotate around the first guide shaft 221, allowing the second guide shaft 222 to enter the second guide groove 212 and slide within it. This allows the first hinge member 210 and the second hinge member 220 to continue rotating relative to each other, and during this process, they can rotate at a large angle around the first guide shaft 221, thus enabling the door 120 to open quickly.

[0118] Under the condition that the first guide shaft 221 slides toward the first end, the second guide shaft 222 can slide in the second guide groove 212 in the forward or reverse direction.

[0119] like Figure 13 and Figure 14 As shown, under the condition that the first guide shaft 221 can slide in the opposite direction to the first end along the first guide groove 211, the second guide shaft 222 can continue to slide along the second guide groove 212 away from the first guide groove 211 to the end of the second guide groove 212 away from the first guide groove 211, so as to avoid interference.

[0120] like Figures 14-17 As shown, the first guide shaft 221 can continue to slide in the opposite direction to the first end along the first guide groove 211, thereby driving the second guide shaft 222 to slide in the opposite direction to the first guide groove 211 along the second guide groove 212, gradually exiting the second guide groove 212 and returning to the first guide groove 211. During this process, the relative rotation angle between the first hinge member 210 and the second hinge member 220 further increases.

[0121] When the second guide shaft 222 slides to the first guide groove 211 and the second guide shaft 222 is located on the side of the first guide shaft 221 near the second end, the second guide shaft 222 and the first guide shaft 221 can slide simultaneously towards the second end within the first guide groove 211.

[0122] In this embodiment, such as Figure 17 and Figure 18 As shown, when the second guide shaft 222 slides in the opposite direction to the first guide groove 211, the first guide shaft 221 has already slid to the side of the second guide shaft 222 closer to the first end. The second guide shaft 222 and the first guide shaft 221 can slide towards the second end simultaneously in the first guide groove 211. During this process, the relative rotation angle between the first hinge member 210 and the second hinge member 220 further increases.

[0123] According to the hinge assembly 200 of the present application embodiment, another embodiment of the hinge assembly 200 is provided, in which the first hinge member 210 and the second hinge member 220 rotate at a larger angle relative to each other, thereby making the opening angle of the door 120 larger, reaching more than 180°. In the case of non-embedded installation, it can realize ultra-large angle opening and can adapt to more usage scenarios.

[0124] According to some embodiments of this application, such as Figures 11-18 As shown, when the first guide shaft 221 is located on the side of the second guide shaft 222 near the second end and slides along the first guide groove 211 towards the second end, the second hinge member 220 rotates at an angle of 0°-45° relative to the first hinge member 210; and / or, when the second guide shaft 222 slides within the second guide groove 212, the second hinge member 220 rotates at an angle of 45°-125° relative to the first hinge member 210; and / or, when the first guide shaft 221 slides within the first guide groove 211 towards the first end, the second hinge member 220 rotates at an angle of 45°-180° relative to the first hinge member 210; and / or, when the second guide shaft 222 is located on the side of the first guide shaft 221 near the second end and slides along the first guide groove 211 towards the second end, the second hinge member 220 rotates at an angle of 180°-210° relative to the first hinge member 210.

[0125] In this embodiment, reference Figure 11 and Figure 12When the first guide shaft 221 is located on the side of the second guide shaft 222 near the second end and moves towards the second end along the first guide groove 211, the second guide shaft 222 is also located in the first guide groove 211 and slides towards the second end simultaneously with the first guide shaft 221. The rotation angle of the second hinge member 220 relative to the first hinge member 210 is 0°-45°. As the first guide shaft 221 moves towards the second end, the relative rotation angle between the second hinge member 220 and the first hinge member 210 gradually increases. During this process, the first hinge member 210 and the second hinge member 220 undergo a certain displacement along the line connecting the axes of the first guide shaft 221 and the second guide shaft 222. Taking the second hinge member 220 as a reference, the first hinge member 210 displaces a certain distance relative to the second hinge member 220 from the axis of the first guide shaft 221 towards the axis of the second guide shaft 222. This allows the door body 120 to have a certain lateral displacement relative to the main body 110 during the rotation, ensuring that the side of the door body 120 does not extend beyond the frame of the main body 110. For example, as... Figure 12 As shown, when the first guide shaft 221 is moved to the second end, the relative rotation angle between the first hinge member 210 and the second hinge member 220 can be 26°, 30°, 35°, 40°, 45°, or other angles between 25° and 45°, which are not limited here.

[0126] In this embodiment, reference Figures 13-15 Under the condition that the second guide shaft 222 slides within the second guide groove 212, the first guide shaft 221 can first rotate at its second end, that is, the first hinge member 210 rotates around the first guide shaft 221. Then, the first guide shaft 221 moves in the opposite direction along the first guide groove 211 towards the first end, and the second hinge member 220 rotates relative to the first hinge member 210 at an angle of 45°-125°. Figure 14 As shown, when the second guide shaft 222 slides to a certain distance from the end of the second guide groove 212 away from the first guide groove 211, and the first guide shaft 221 is also a certain distance from the second end, the relative rotation angle between the first hinge member 210 and the second hinge member 220 is 90°. As the second guide shaft 222 continues to slide along the second guide groove 212 away from the first guide groove 211, the first guide shaft 221 moves towards the first end. When the second guide shaft 222 slides to the end of the second guide groove 212 away from the first guide groove 211, the relative rotation angle between the first hinge member 210 and the second hinge member 220 can be 115°, 117°, 119°, 120°, 122°, 124°, 125°, or other angles between 115° and 125°, which are not limited here.

[0127] In this embodiment, reference Figure 16 and Figure 17Under the condition that the first guide shaft 221 slides towards the first end within the first guide groove 211, the second guide shaft 222 first moves away from the first guide groove 211 along the second guide groove 212 to the end, and then moves towards the first guide groove 211 along the second guide groove 212 until it exits the second guide groove 212. The second hinge member 220 rotates relative to the first hinge member 210 at an angle of 45°-180°. As the first guide shaft 221 moves closer to the first end, the relative rotation angle between the first hinge member 210 and the second hinge member 220 gradually increases. For example, in the case of non-zero embedded installation, when the first guide shaft 221 slides to the first end, the relative rotation angle between the first hinge member 210 and the second hinge member 220 can be 175°, 177°, 179°, 180°, 182°, 184°, 185° or other angles between 175° and 185°, which are not limited here.

[0128] In this embodiment, reference Figure 17 and Figure 18 With the second guide shaft 222 located on the side of the first guide shaft 221 near the second end and sliding towards the second end along the first guide groove 211, compared to the initial state, both the first guide shaft 221 and the second guide shaft 222 move along the first guide groove 211. However, the relative positions of the first guide shaft 221 and the second guide shaft 222 within the first guide groove 211 change, and the second hinge member 220 rotates at an angle of 180°-210° relative to the first hinge member 210. As the second guide shaft 222 moves towards the second end... As the second end slides, the relative rotation angle of the first hinge member 210 and the second hinge member 220 increases. When the second guide shaft 222 moves to the second end or interferes with the front side of the door body 120 and the side wall of the main body 110, the relative rotation angle of the first hinge member 210 and the second hinge member 220 reaches its limit. For example, this limit angle can be 200°, 202°, ​​204°, 206°, 208°, 210° or other angles between 200° and 210°, which are not limited here.

[0129] According to some of its own embodiments, such as Figures 11-18 As shown, the predetermined trajectories of the first guide groove 211 and the second guide groove 212 can both be arranged in an arc shape. One end of the second guide groove 212 in the length direction is connected to the side of the first guide groove 211 away from its own center. The center of the second guide groove 212 can be located on the side of the second guide groove 212 facing the second end.

[0130] In this embodiment, one end of the second guide groove 212 can be connected to the middle section of the first guide groove 211 so that the predetermined trajectory of the second guide groove 212 and the first guide groove 211 forms a Y-shaped structure.

[0131] In this embodiment, the predetermined trajectory of the first guide groove 211 can be arranged in an arc shape, and in the initial state of the hinge assembly 200, the center of the predetermined trajectory of the first guide groove 211 is located on the side of the door body 120 away from the main body 110, so that when the door body 120 is opened from the initial state to the first guide shaft 221 moving to the second end, the rotation of the door body 120 will be accompanied by a lateral displacement, that is, the side of the door body 120 will have a displacement in the direction close to the center of the door body 120, so that the side of the door body 120 will not exceed the plane where the side wall of the main body 110 is located.

[0132] The center of the second guide groove 212 is located on the side of the second guide groove 212 facing the second end, so that the second guide shaft 222 can slide within the second guide groove 212 when the first guide shaft 221 is located on the side of the second guide groove 212 facing the second end. The second guide groove 212 is located on the side of the first guide groove 211 away from its own center, so that when the second guide shaft 222 slides within the second guide groove 212, the first hinge member 210 and the second hinge member 220 can be further rotated and opened relative to each other in the forward direction.

[0133] In some embodiments, the limiting part can be a protrusion provided at the bottom of the second guide groove 212, and the end of the second guide shaft 222 can be provided with a recess. When the second guide shaft 222 moves to a position corresponding to the protrusion, at least a part of the protrusion can extend into the recess to cooperate with the recess, thereby achieving the limiting function.

[0134] According to some embodiments of this application, such as Figure 4 As shown, the limiting part may include at least two protrusions 213 provided on the side wall of the second guide groove 212. The two protrusions 213 may be spaced apart along the length direction of the second guide groove 212. When the first hinge member 210 and the second hinge member 220 are rotated relative to each other to 85°-95°, the second guide shaft 222 may be located between the two protrusions 213.

[0135] In this embodiment, the sidewall of the second guide groove 212 may be provided with at least two protrusions 213. The two protrusions 213 are provided on the sidewall of the second guide groove 212 away from the first guide groove 211, and the two protrusions 213 are located at the entrance of the second guide groove 212. When the first hinge member 210 and the second hinge member 220 rotate relative to each other to 85°-95°, the second guide shaft 222 moves between the two protrusions 213. It can be understood that the protrusion height of the protrusions 213 is greater than the fitting clearance between the second guide shaft 222 and the second guide groove 212, so as to play an effective limiting role.

[0136] By setting two protrusions 213 and spacing them apart, the second guide shaft 222 is limited in both directions, thus improving the limiting effect.

[0137] In some embodiments, multiple protrusions 213 may be provided, and the specific number is not limited here. There may be three, four, five or more protrusions. By providing multiple protrusions 213, the door body 120 can be limited at multiple angles, thereby improving the user experience.

[0138] According to some embodiments of this application, such as Figures 2-4 As shown, 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, and the length of the second guide shaft 222 can be less than or equal to the depth of the second guide groove 212.

[0139] It should be noted that the length directions of the first guide shaft 221 and the second guide shaft 222 can be arranged in parallel, and the depth directions 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 facilitate a single guide shaft to slide with different guide grooves.

[0140] In this embodiment, the depths of the first guide groove 211 and the second guide groove 212 can be set differently, and the lengths of the first guide shaft 221 and the second guide shaft 222 can be set differently. Specifically, 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. This ensures that during rotation of the hinge assembly 200, the first guide shaft 221 will not interfere with the bottom of the first guide groove 211, and the first guide shaft 221 will not enter the second guide groove 212.

[0141] The length of the second guide shaft 222 is less than or equal to the depth of the second guide groove 212, and thus the length of the second guide shaft 222 is even less than or equal to the depth of the first guide groove 211, so that the second guide shaft 222 can slide with the first guide groove 211 or enter the second guide groove 212 and slide with the second guide groove 212.

[0142] By limiting the first guide shaft 221 to sliding engagement with the first guide groove 211, the rotation trajectory of the hinge assembly 200 is constrained to a certain extent, making the movement trajectory of the hinge assembly 200 more stable during the opening process and improving ease of use.

[0143] According to some embodiments of this application, such as Figure 2 As shown, the end of the guide shaft can be spaced apart from the bottom of the guide groove.

[0144] In this embodiment, the end of the guide shaft, that is, the end of the guide shaft facing the bottom of the guide groove, is designed to be spaced apart from the bottom of the guide groove, so as to reduce the interference and friction loss generated during the relative rotation of the first hinge member 210 and the second hinge member 220, and improve the durability of the component.

[0145] 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 apart 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 apart from the bottom of the guide groove.

[0146] According to some embodiments of this application, such as Figures 5-18 As shown, the radial dimensions of the first guide shaft 221 and the second guide shaft 222 can be set to be the same.

[0147] In this embodiment, the width of the guide groove can be uniformly set in its length direction. By setting the radial dimensions 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 is improved, and the stability of the relative rotation of the first hinge member 210 and the second hinge member 220 is improved.

[0148] The width of the first guide groove 211 and the second guide groove 212 can be set to be the same, so that the guide shaft can slide with different guide grooves, and the stability of the relative rotation trajectory of the first hinge member 210 and the second hinge member 220 can be guaranteed when the guide groove moves in different guide grooves.

[0149] Understandably, the guide shaft and guide groove can be clearance fit to reduce the frictional resistance between the inner walls of the guide shaft and guide groove, thereby improving the smoothness of the hinge assembly 200 during rotation.

[0150] In some embodiments, the radial dimensions of the guide shafts can be set differently. For example, the width of the second guide groove 212 can be smaller than the width of the first guide groove 211, wherein the radial dimension of the first guide shaft 221 can be larger than the width of the second guide groove 212 and smaller than the width of the first guide groove 211, and the radial dimension of the second guide shaft 222 can be smaller than the width of the second guide groove 212. Thus, when the hinge assembly 200 is rotated, the second guide shaft 222 can move within the first guide groove 211 or into the second guide groove 212, while the first guide shaft 221 can only move within the first guide groove 211, thus constraining the movement trajectory to a certain extent.

[0151] In some embodiments, such as Figures 5-18 As shown, the cross-section of the guide shaft along its length can be circular to facilitate sliding and rotating within the guide groove. The smooth surface of the guide shaft makes it less likely to interfere with the inner wall of the guide groove and reduces frictional resistance, resulting in high structural strength.

[0152] In this embodiment, the ends of the first guide groove 211 and the second guide groove 212 are arranged in an arc shape in the depth direction to facilitate cooperation with the guide shaft and facilitate rotation around the guide shaft.

[0153] Based on the same concept, such as Figure 1 As shown, this application embodiment also provides a storage device 100, which includes a main body 110, a door 120 and a hinge assembly 200. The front side of the main body 110 has an opening, and the door 120 is hinged to the front side of the main body 110 through the hinge assembly 200 so that the door 120 can open and close the opening of the main body 110.

[0154] In this embodiment, one of the first hinge component 210 and the second hinge component 220 is installed on the main body 110 and the other is installed on the door body 120. When the door body 120 is opened to 90°, the side of the door body 120 does not extend beyond the plane of the side wall of the main body 110.

[0155] It should be noted that both the upper and lower ends of the door body 120 can be connected to the main body 110 via hinge assemblies 200, thereby improving the connection strength and rotational stability. It should be further noted that the installation positions of the first hinge component 210 and the second hinge component 220 on the main body 110 and the door body 120 can be interchanged, both achieving the purpose of this application.

[0156] For example, the first hinge member 210 can be installed on the door body 120, and the second hinge member 220 can be installed on the main body 110. (See reference) Figure 1 , Figure 2 and Figure 6 In this example, the first hinge member 210, which is arranged in a block shape, is embedded in the door body 120. One end of the seat of the second hinge member 220 is fixedly connected to the main body 110, and the other end extends out of the front side of the main body 110. The first guide shaft 221 and the second guide shaft 222 of the second hinge member 220 are installed on the part of the seat that extends out of the main body 110.

[0157] In another example, the first hinge 210 can be installed on the body 110, and the second hinge 220 can be installed on the door 120.

[0158] The storage device 100 provided in the application embodiment has a simple structure and low cost by using the hinge assembly 200 as described above. The opening process is smooth, and the side of the door 120 will not exceed the plane of the side wall of the main body 110 during the process of opening the door 120 to 90°, thus meeting the requirements for embedded installation.

[0159] According to some embodiments of this application, such as Figures 2-18 As shown, when the door 120 is in the closed position, the first guide shaft 221 can be located on the side of the second guide shaft 222 closer to the main body 110, and the first guide groove 211 can be located on the side of the second guide groove 212 away from the main body 110.

[0160] In this embodiment, when the door 120 is in the closed position, i.e., when the hinge assembly 200 is in its initial state, the first guide shaft 221 can be located on the side of the second guide shaft 222 closer 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 120. The first guide groove 211 can be located on the side of the second guide groove 212 away from the main body 110. This allows the first hinge member 210 and the second hinge member 220 to rotate relative to each other along a predetermined trajectory. During rotation, the door 120 has a displacement along a direction close to the center of the door 120, so that the side of the door 120 does not extend beyond the side wall of the main body 110, thus satisfying the requirements for a refrigerator with zero-embedded installation.

[0161] According to some embodiments of this application, the storage device 100 can be at least one of a refrigerator, freezer, oven, and microwave oven.

[0162] In other embodiments, display cabinets, medicine cabinets, kitchen cabinets, wine cabinets, wardrobes, and other home appliances or furniture are used, and no specific restrictions are imposed here.
