Box device and refrigeration equipment

Abstract

The application discloses a box device and a refrigeration equipment. The box device comprises a box, a door body, a hinge assembly and a self-locking assembly. The self-locking assembly comprises an elastic member and a clamping member. The clamping member has a most convex point and a locking position. After the elastic member passes the most convex point of the clamping member, the elastic member enters the locking position under the elastic force, thereby locking the door body in a closed state. Before the elastic member contacts the clamping member, the sliding shaft moves in a first interval of the sliding groove. Before the elastic member contacts the clamping member and reaches the most convex point, the sliding shaft moves in a second interval of the sliding groove. During the process that the elastic member reaches the locking position from the most convex point, the sliding shaft moves in a third interval of the sliding groove. The width of at least the interval of the third interval of the sliding groove close to the locking position is greater than the width of the first interval of the sliding groove. The gap between the sliding shaft and the sliding groove is large, and the friction between the sliding shaft and the sliding groove is small. The smoothness of the small-angle door closing is effectively improved, and the closure of the door body and the box is ensured.

Description

Technical Field

[0001] This application belongs to the field of refrigeration equipment technology, specifically relating to enclosure devices and refrigeration equipment. Background Technology

[0002] For enclosure devices with a door and a box, the door and box are usually connected by a hinge, allowing the door to rotate relative to the box. Currently, the self-locking structure of the hinge between the box and the door usually uses a combination of a self-locking hook and the hinge to produce a self-locking effect. However, when the door is at a small angle, the self-locking force may be insufficient, resulting in the door failing to close. Summary of the Invention

[0003] This application provides a housing device and a refrigeration equipment to solve the technical problem of insufficient self-locking force in existing self-locking hook and hinge assemblies.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution: a box-type device, comprising: a box body, wherein the box body has an internal accommodating space, wherein the accommodating space has an opening; a door body, wherein the door body is used to block the opening; a hinge assembly, disposed on the pivot side of the box body and pivotally connecting the box body and the door body; the hinge assembly includes a first connecting member and a second connecting member, the first connecting member being disposed on one of the box body and the door body, and the second connecting member being disposed on the other; the first connecting member having at least a sliding shaft, and the second connecting member having at least a sliding groove, wherein when the door body pivots relative to the box body, the sliding shaft moves along the sliding groove, and the sliding groove includes a transition area; a self-locking assembly, wherein the self-locking assembly includes an elastic member and a locking member, wherein when the door body is opened... During the process of rotating from the open state to the closed state relative to the housing, the elastic element and the locking element transition from being separated from each other to being in contact with each other. The elastic deformation of the elastic element under the action of the locking element generates a lateral pushing force. The lateral pushing force generates a relative movement tendency along the radial direction of the sliding shaft between the sliding shaft and the groove wall of the sliding groove. During at least partial contact between the elastic element and the locking element, the sliding shaft is located in the transition region. When the sliding shaft is located in the transition region, there is a first radial gap between the sliding shaft and the groove wall of the sliding groove. When the sliding shaft is located in at least a portion of other groove segments outside the transition region, there is a second radial gap between the sliding shaft and the groove wall of the sliding groove. The first radial gap is smaller than the second radial gap.

[0005] To solve the above-mentioned technical problems, another technical solution adopted in this application is: a refrigeration device, wherein the refrigeration device adopts the above-mentioned box device.

[0006] The beneficial effects of this application are: when the door is rotated to a near-closed state, that is, when the sliding shaft is located in the third section of the slide groove, since the width of at least a portion of the third section corresponding to the locking position of the elastic element is greater than the width of the first section of the slide groove, the clearance between the sliding shaft and the slide groove is larger, the friction between the sliding shaft and the slide groove is smaller, thus avoiding affecting the rebound force of the elastic element, effectively improving the smoothness of closing the door at a small angle, ensuring the closure of the door and the cabinet, and improving the quality of the cabinet door device.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] Please see Figures 1 to 4 , Figure 1 This is a partial structural schematic diagram of an embodiment of the housing device of this application. At this time, the housing device is in a closed state. Figure 2 This is a partial exploded structural diagram of an embodiment of the box device of this application; Figure 3 This is a schematic diagram of the structure of the second connecting member of an embodiment of the housing device of this application; Figure 4 yes Figure 3 Enlarged view of part A in the middle.

[0031] One embodiment of this application provides a cabinet device 100. The cabinet device 100 includes a cabinet 110, a door 120, and a hinge assembly 130. The cabinet 110 has an internal receiving space with an opening. The door 120 is used for sealing or opening. The hinge assembly 130 is disposed on the pivot side of the cabinet 110, pivotally connecting the door 120 and the cabinet 110, thus achieving a rotational connection between the cabinet 110 and the door 120. The door 120 can be opened or closed relative to the cabinet 110 under the action of the hinge assembly 130. The hinge assembly 130 includes a first connector 131 and a second connector 132. The first connector 131 is disposed on one of the cabinet 110 and the door 120, and the second connector 132 is disposed on the other of the door 120 and the cabinet 110. The first connecting member 131 is provided with at least a first sliding shaft 1311, and the second connecting member 132 is provided with at least a first sliding groove 1321. During the pivotal rotation of the door body 120 relative to the housing 110, the first sliding shaft 1311 moves along the first sliding groove 1321. Specifically, the first connecting member 131 is provided on the door body 120, and the second connecting member 132 is provided on the housing 110; or the first connecting member 131 is provided on the door body 120, and the second connecting member 132 is provided on the housing 110.

[0032] The first slide groove 1321 is provided with a first interference region 133, and the first sliding shaft 1311 is interference-fitted with the first slide groove 1321 in the first interference region 133. At least one side wall of the first slide groove 1321 in the first interference region 133 has a first elastic segment 1331, and the first elastic segment 1331 has a first maximum interference point 1332. When the door 120 rotates toward the housing 110 until the first sliding shaft 1311 passes the first maximum interference point 1332, the rebound force of the first elastic segment 1331 causes the door 120 to rotate toward the housing 110, thereby realizing the automatic closing of the door 120.

[0033] The cabinet device 100 of this application has a first interference region 133 in the first slide groove 1321, and the first interference region 133 has a first elastic segment 1331. When the first sliding shaft 1311 is pressed and passes the first maximum interference point 1332 of the first elastic segment 1331, the rebound force of the first elastic segment 1331 drives the first sliding shaft 1311 to continue moving along the first slide groove 1321, and the door 120 continues to rotate toward the cabinet 110. Even if the user's pushing force is lost, the door 120 can still close automatically. The cabinet device 100 of this application does not require corresponding self-locking devices on the first connector 131 and the second connector 132, which simplifies the self-locking structure, reduces costs, and makes the appearance more concise and beautiful.

[0034] Specifically, during the process of the door 120 rotating from the open state to the closed state relative to the housing 110, the user pushes the door 120, and the first sliding shaft 1311 moves along the first sliding groove 1321. When the door 120 rotates relative to the housing 110 to a certain angle, the first sliding shaft 1311 presses the first elastic segment 1331, and the first elastic segment 1331 deforms. After the first sliding shaft 1311 passes the first maximum interference point 1332, even if the user stops pushing the door 120, the rebound force generated by the deformation of the first elastic segment 1331 can be converted into a self-locking force, and push the first sliding shaft 1311 to continue moving along the first sliding groove 1321. The door 120 continues to rotate towards the housing 110 until the magnetic strip of the housing 110 and the door 120 are attracted, and the door 120 is in the closed state. Users do not need to push the door 120 completely to close it with the housing 110. Instead, the door 120 can be closed automatically after being closed to a certain angle, which ensures the tightness of the closure between the door 120 and the housing 110 and improves the convenience of use.

[0035] It should be noted that the position of the first interference region 133 within the first slide groove 1321 can be adjusted according to actual conditions. When the first sliding shaft 1311 moves to the first highest interference point within the first slide groove 1321, the opening angle of the door 120 relative to the housing 110 is a preset angle. The position of the first interference region 133 within the first slide groove 1321 can be adjusted according to the specific value of the preset angle, and the parameters of the first elastic segment 1331 can also be adjusted. This allows the door 120 to rotate towards the housing 110 using the rebound force of the first elastic segment 1331 at the preset angle, thus achieving automatic closing of the door 120. The preset angle can be 10°-30°, such as 10°, 15°, 30°, etc., or 30°-60°, such as 30°, 45°, or 60°, etc. The preset angle can also be greater than 60° or less than 10°, and can be adjusted according to actual conditions.

[0036] To ensure smoother movement of the first sliding shaft 1311 within the first sliding groove 1321, in some embodiments, the first elastic segment 1331 is configured such that, in its natural state, the width of the first sliding groove 1321 gradually decreases from both sides of the first maximum interference point 1332 towards the first maximum interference point 1332. Thus, as the first sliding shaft 1311 moves within the first sliding groove 1321, the width of the first sliding groove 1321 gradually changes. The first sliding shaft 1311 can gradually compress or release the first elastic segment 1331, ensuring smooth movement of the first sliding shaft 1311 within the first sliding groove 1321 and preventing jamming, thus guaranteeing smooth opening and closing of the door 120. It should be noted that the first direction is defined as the direction perpendicular to the movement direction of the first sliding shaft 1311 within the first sliding groove 1321, and the distance between the intersection of the first direction and the two side walls of the first sliding groove 1321 is defined as the width of the first sliding groove 1321.

[0037] Furthermore, to avoid jamming when closing and to generate a greater self-locking force, the first elastic segment 1331 includes a first front interference segment 1333 and a first rear interference segment 1334 located on either side of the first maximum interference point 1332. When the door 120 rotates towards the housing 110, the first sliding shaft 1311 passes through the first front interference segment 1333 and the first rear interference segment 1334 successively. The slope of the first rear interference segment 1334 is greater than that of the first front interference segment 1333. The slope of the first front interference segment 1333 is relatively gentle, which facilitates the door 120 to gradually compress the first front interference segment 1333. When the first sliding shaft 1311 passes through the first front interference segment 1333, the door 120 closes smoothly, avoiding jamming and improving the closing experience of the door 120. The slope of the first rear interference section 1334 is relatively steep. After the first sliding shaft 1311 passes the first maximum interference point 1332, the rebound process of the first rear interference section 1334 is relatively fast, which can generate a large self-locking force to push the first sliding shaft 1311 to move along the first sliding groove 1321. The rebound force of the first rear interference section 1334 causes the door 120 to rotate towards the box 110, which can realize the automatic closing of the door 120.

[0038] In some embodiments, the first elastic segment 1331 is an elastic layer attached to the groove wall of the first slide rail 1321. By providing the first elastic segment 1331 on the groove wall of the first slide rail 1321, after the door 120 rotates toward the housing 110 until the first sliding shaft 1311 passes the first maximum interference point 1332, the rebound force of the first elastic segment 1331 causes the door 120 to rotate toward the housing 110, thereby achieving automatic closing of the door 120. The first elastic segment 1331 may be made of a resilient material, such as polyoxymethylene. In other embodiments, the first elastic segment 1331 is formed by the groove wall of the resilient first slide rail 1321. The groove wall of the first slide rail 1321 is made of a resilient material, such as polyoxymethylene. Further, the second connector 132 is formed of polyoxymethylene, such as polyoxymethylene.

[0039] Specifically, the two side walls of the first slide groove 1321 are each provided with a first elastic segment 1331 in the first interference region 133. When the first sliding shaft 1311 moves along the first slide groove 1321, the first sliding shaft 1311 presses against the first elastic segments 1331 on both sides, and the rebound force of the first elastic segments 1331 on both sides causes the door 120 to rotate towards the box 110. The rebound force of the first elastic segments 1331 on both side walls can effectively push the first sliding shaft 1311, causing the door 120 to rotate towards the box 110.

[0040] In some embodiments, a second sliding shaft 1312 is further provided on one of the first connecting member 131 and the second connecting member 132, and a second sliding groove 1322 is further provided on the other of the first connecting member 131 and the second connecting member 132. When the door body 120 pivots relative to the box body 110, the second sliding shaft 1312 moves along the second sliding groove 1322. The second sliding groove 1322 is provided with a second interference region 134. The second sliding shaft 1312 is interference-fitted with the second sliding groove 1322 in the second interference region 134. At least one side of the groove wall of the second sliding groove 1322 in the second interference region 134 has a second elastic segment 1341. The second elastic segment 1341 has a second maximum interference point 1342. When the door body 120 rotates toward the box body 110 until the second sliding shaft 1312 passes the second maximum interference point 1342, the rebound force of the second elastic segment 1341 causes the door body 120 to rotate toward the box body 110.

[0041] The housing device 100 of this application may adopt a single-axis or dual-axis hinge assembly 130, or a three-axis or more hinge assembly 130.

[0042] By providing a second interference region 134 within the second slide groove 1322, and the second interference region 134 having a second elastic segment 1341, when the second sliding shaft 1312 presses against and passes the second maximum interference point 1342 of the second elastic segment 1341, the rebound force of the second elastic segment 1341 drives the second sliding shaft 1312 to continue moving along the second slide groove 1322, and the door 120 continues to rotate toward the box 110 side. Even without the user's pushing force, the door 120 can still close automatically. The box device 100 of this application, through the rebound force of the first elastic segment 1331 and the second elastic segment 1341, eliminates the need for corresponding self-locking devices on the first connector 131 and the second connector 132, simplifying the self-locking structure, reducing costs, and resulting in a simpler and more aesthetically pleasing appearance.

[0043] During the process of the door 120 rotating from the open state to the closed state relative to the housing 110, the user pushes the door 120, and the second sliding shaft 1312 moves along the second sliding groove 1322. When the door 120 rotates to a certain angle relative to the housing 110, the second sliding shaft 1312 presses the second elastic segment 1341, and the second elastic segment 1341 deforms. After the second sliding shaft 1312 passes the second maximum interference point 1342, even if the user no longer pushes the door 120, the rebound force generated by the deformation of the second elastic segment 1341 can be converted into a self-locking force, and push the second sliding shaft 1312 to continue moving along the second sliding groove 1322. The door 120 continues to rotate towards the housing 110 until the magnetic strip of the housing 110 and the door 120 are attracted, and the door 120 is in the closed state. Users do not need to push the door 120 completely to close it with the housing 110. Instead, the door 120 can be closed automatically after being closed to a certain angle, which ensures the tightness of the closure between the door 120 and the housing 110 and improves the convenience of use.

[0044] Specifically, the second sliding shaft 1312 can be disposed on the first connecting member 131, and the corresponding second sliding groove 1322 can be disposed on the second connecting member 132. That is, the first sliding shaft 1311 and the second sliding shaft 1312 are disposed on the first connecting member 131, and the first sliding groove 1321 and the second sliding groove 1322 are disposed on the second connecting member 132. Alternatively, the second sliding groove 1322 can be disposed on the first connecting member 131, and the corresponding second sliding shaft 1312 can be disposed on the second connecting member 132. That is, the first sliding shaft 1311 and the second sliding groove 1322 are disposed on the first connecting member 131, and the second sliding shaft 1312 and the first sliding groove 1321 are disposed on the second connecting member 132.

[0045] To facilitate smoother movement of the second sliding shaft 1312 within the second slide groove 1322, in some embodiments, the second elastic segment 1341 is configured such that, in its natural state, the width of the second slide groove 1322 gradually decreases from both sides of the second maximum interference point 1342 towards the second maximum interference point 1342. This allows the width of the second slide groove 1322 to gradually change as the second sliding shaft 1312 moves within it, enabling the second sliding shaft 1312 to gradually compress or release the second elastic segment 1341. This ensures smooth movement of the second sliding shaft 1312 within the second slide groove 1322 and prevents jamming. It should be noted that the second direction is defined as the direction perpendicular to the movement direction of the second sliding shaft 1312 within the second slide groove 1322, and the distance between the intersection points of the second direction and the two side walls of the second slide groove 1322 is defined as the width of the second slide groove 1322.

[0046] In some embodiments, the second elastic segment 1341 is an elastic layer attached to the groove wall of the second slide rail 1322. By providing the second elastic segment 1341 on the groove wall of the second slide rail 1322, after the door 120 rotates toward the housing 110 until the second sliding shaft 1312 passes the second maximum interference point 1342, the rebound force of the second elastic segment 1341 causes the door 120 to rotate toward the housing 110, thereby achieving automatic closing of the door 120. The second elastic segment 1341 can be made of a resilient material, such as polyoxymethylene. In other embodiments, the first elastic segment 1331 is formed by the groove wall of the resilient first slide rail 1321. The groove wall of the second slide rail 1322 is made of a resilient material, such as polyoxymethylene. Further, the connector where the second slide rail 1322 is located is made of polyoxymethylene, such as polyoxymethylene.

[0047] Specifically, the two side walls of the second slide groove 1322 are each provided with a second elastic segment 1341 in the second interference region 134. When the second slide shaft 1312 moves along the second slide groove 1322, the second slide shaft 1312 presses against the second elastic segments 1341 on both sides, and the rebound force of the second elastic segments 1341 on both sides causes the door 120 to rotate towards the box 110. The rebound force of the second elastic segments 1341 on both side walls can effectively push the second slide shaft 1312, causing the door 120 to rotate towards the box 110.

[0048] Furthermore, when the door 120 rotates relative to the housing 110, the first sliding shaft 1311 and the second sliding shaft 1312 simultaneously enter and leave the first interference region 133 and the second interference region 134, respectively. Thus, the force exerted by the first interference region 133 on the first sliding shaft 1311 and the force exerted by the second interference region 134 on the second sliding shaft 1312 can simultaneously form a resultant force, making the door 120 rotate more smoothly and avoiding jamming when opening and closing the door.

[0049] Furthermore, when the door 120 rotates relative to the housing 110, the first sliding shaft 1311 and the second sliding shaft 1312 pass through the first maximum interference point 1332 and the second maximum interference point 1342 simultaneously, so that the maximum rebound force of the first elastic segment 1331 on the first sliding shaft 1311 and the maximum rebound force of the second elastic segment 1341 on the second sliding shaft 1312 can simultaneously form a resultant force, making the door 120 rotate towards the housing 110 side, making the rotation of the door 120 smoother and better achieving the self-closing of the door 120.

[0050] It should be noted that the first interference region 133 in this application can function as a self-locking component in the following embodiments, and other structures in the following embodiments can be adapted to this application.

[0051] Please see Figures 5 to 8 , Figure 5This is a partial structural schematic diagram of another embodiment of the housing device of this application, in which the housing device is in the open state; Figure 6 This is a partial structural schematic diagram of another embodiment of the housing device of this application, in which the housing device is in a closed state; Figure 7 This is a structural schematic diagram of the second connecting member of another embodiment of the housing device of this application; Figure 8 This is a schematic diagram of the structure of the first connecting member of another embodiment of the housing device of this application.

[0052] One embodiment of this application provides a housing 210 device 200. The housing 210 device 200 includes a housing 210, a door 220, a hinge assembly 230, and a self-locking assembly 240. The housing 210 has an internal receiving space with an opening. The door 220 is used for sealing or opening. The hinge assembly 230 is positioned on the pivot side of the housing 210, pivotally connecting the door 220 and the housing 210, thus achieving a rotational connection between the housing 210 and the door 220. The door 220 can be opened or closed relative to the housing 210 under the action of the hinge assembly 230. The self-locking assembly 240 includes an elastic member 241 and a locking member 242. The elastic member 241 is disposed on one of the housing 210 and the door 220, and the locking member 242 is disposed on the other. The latching member 242 has a maximum protrusion 2421 and a locking position 2422. The maximum protrusion 2421 is the position on the latching member 242 that causes the elastic member 241 to have the greatest elastic deformation. When the door 220 rotates from the open state to the closed state relative to the box 210, the elastic member 241 and the latching member 242 come into contact with each other. After the elastic member 241 passes the maximum protrusion 2421 of the latching member 242, it enters the locking position 2422, thereby locking the door 220 in the closed state.

[0053] The transition between the most prominent point 2421 and the locking position 2422 is continuous and smooth. As the elastic element 241 moves from the most prominent point 2421 to the locking position 2422, its deformation gradually recovers, and its rebound force is gradually released. This causes the door 220 to gradually rotate towards the housing 210 under the rebound force, thus achieving automatic closing of the door 220. The deformation, rebound, and release process of the elastic element 241 in the housing 210 device 200 of this application is smooth, without obvious sudden force inflection points, avoiding shaking and jerking of the door 220 during closing, reducing noise during closing, and improving the user experience.

[0054] Specifically, during the process of the door 220 rotating from the open state to the closed state relative to the housing 210, the user pushes the door 220. When the door 220 rotates to a certain angle relative to the housing 210, the latching member 242 contacts and squeezes the elastic member 241. After the elastic member 241 passes the most protruding point 2421 of the latching member 242, the rebound force generated by the deformation of the elastic member 241 can be converted into a self-locking force that pushes the door 220 to continue rotating towards the housing 210. Since there is a continuous and smooth transition between the most protruding point 2421 and the locking position 2422, and the rebound force of the elastic member 241 is gradually released, the deformation of the elastic member 241 gradually recovers. The door 220 gradually rotates towards the housing 210 side under the rebound force. The door 220 continues to rotate towards the housing 210 until the magnetic strip of the housing 210 and the door 220 are attracted, and the door 220 is in the closed state. Users do not need to push the door 220 completely to close it with the housing 210. Instead, the door 220 can be closed automatically after being closed to a certain angle, which ensures the tightness of the closure between the door 220 and the housing 210 and improves the convenience of use.

[0055] The elastic element 241 can be installed on the door body 220, and the snap-fit ​​element 242 can be installed on the housing 210. Alternatively, the elastic element 241 can be installed on the housing 210, and the snap-fit ​​element 242 can be installed on the door body 220.

[0056] It should be noted that the position of the most prominent point 2421 of the latching member 242 can be adjusted according to the actual situation. The preset angle is the opening angle of the door 220 relative to the housing 210 when the elastic element 241 passes the position of the most prominent point 2421 of the latching member 242. The position of the most prominent point 2421 of the latching member 242 and the parameters of the elastic element 241 can be adjusted according to the specific value of the preset angle. This allows the door 220 to rotate towards the housing 210 using the rebound force of the first elastic segment at the preset angle, thus achieving automatic closing of the door 220. The preset angle can be between 10° and 30°, such as 10°, 15°, 30°, etc. The preset angle can also be greater than 30° or less than 10°, and can be adjusted according to the actual situation.

[0057] In some embodiments, the elastic member 241 is hook-shaped and has a fixed end 2411 and a free end 2412. In the direction from the fixed end 2411 to the free end 2412, the elastic member 241 extends away from the snap fastener 242 and then extends toward the snap fastener 242. The free end 2412 is used to contact the snap fastener 242.

[0058] In some embodiments, the latching member 242 includes a first contact segment 2423 and a second contact segment 2424 located on both sides of the most prominent point 2421. During the process of the door 220 rotating from the open state relative to the housing 210 to the closed state, the elastic member 241 contacts the first contact segment 2423 and the second contact segment 2424 successively. The second contact segment 2424 connects the most prominent point 2421 and the locking position 2422, and the second contact segment 2424 has a continuous and smooth transition.

[0059] During the process of the door 220 rotating from the open state to the closed state towards the housing 210, the first contact segment 2423 first contacts the elastic element 241, and the first contact segment 2423 contacts and presses the elastic element 241; after the elastic element 241 passes the most protruding point 2421 of the latching element 242, the second contact segment 2424 contacts the elastic element 241. The rebound force generated by the deformation of the elastic element 241 can be converted into a self-locking force that pushes the door 220 to continue rotating towards the housing 210. Since the second contact segment 2424 has a continuous and smooth transition, the deformation of the elastic element 241 gradually recovers, so that the rebound force of the elastic element 241 is gradually released, and the door 220 gradually rotates towards the housing 210 under the rebound force until the elastic element 241 contacts the locking position 2422, and the door 220 is in the closed state.

[0060] Specifically, the second contact section 2424 is arranged in an arc shape protruding outward from the latching member 242. During the rotation of the door 220, after the elastic member 241 passes the most prominent point 2421 of the latching member 242, due to the arc shape of the second contact section 2424 protruding outward from the latching member 242, the elastic member 241 gradually moves along the most prominent point 2421 of the second contact section 2424 to the locking position 2422. The elastic member 241 gradually recovers its deformation, and the rebound force of the elastic member 241 is gradually released. The door 220 gradually rotates towards the housing 210 side under the rebound force until it is closed. The door 220 rotates smoothly, avoiding shaking and jerking during the closing process, reducing closing noise, and improving the user experience.

[0061] Furthermore, the first contact segment 2423 has a continuous and smooth transition. During the closing process of the door 220, the elastic element 241 contacts the first contact segment 2423. The deformation process of the elastic element 241 is gradual, which avoids the door 220 from shaking and jamming during rotation.

[0062] In some embodiments, the second contact segment 2424 is arc-shaped, with a radius of curvature greater than or equal to 5 mm, such as 5 mm, 8 mm, 10 mm, or 14 mm. The arc length of the second contact segment 2424 is greater than or equal to 11 mm, such as 11 mm, 15 mm, or 18 mm. During the process of the door 220 rotating from the open state to the closed state, the second contact segment 2424 can gradually reduce the compression on the elastic element 241, the elastic element 241 gradually recovers its deformation, the rebound force of the elastic element 241 is gradually released, and the door 220 gradually rotates towards the housing 210 side under the rebound force until it reaches the closed state. The door 220 rotates smoothly, avoiding shaking and jerking during the closing process, reducing the closing noise of the door 220, and improving the user experience. In other embodiments, the second contact segment 2424 can be composed of multiple arc segments with different radii to form a smooth streamline shape. As the elastic element 241 moves from the most protruding point 2421 into the locking position 2422, the deformation of the elastic element 241 gradually recovers and the rebound force of the elastic element 241 is gradually released.

[0063] During the contact between the elastic element 241 and the second contact segment 2424, the rotation angle of the door 220 relative to the housing 210 is greater than 10°, such as 10°, 14°, 16°, or 20°. As the door 220 rotates sufficiently relative to the housing 210, the elastic element 241 gradually recovers its deformation, and its rebound force is gradually released. The door 220 then rotates towards the housing 210 under the rebound force until it is closed. This smooth rotation of the door 220 avoids shaking and jerking during closing, reduces closing noise, and improves the user experience.

[0064] In some embodiments, the hinge assembly 230 includes a first connector 231 and a second connector 232. The first connector 231 is disposed on one of the housing 210 and the door 220, and the second connector 232 is disposed on the other. Specifically, the first connector 231 is disposed on the door 220, and the second connector 232 is disposed on the housing 210; or the first connector 231 is disposed on the door 220, and the second connector 232 is disposed on the housing 210.

[0065] The first connecting member 231 and the second connecting member 232 are respectively provided with a first sliding shaft 2311 and a first sliding groove 2321 that cooperate with each other, as well as a second sliding shaft 2312 and a second sliding groove 2322 that cooperate with each other. When the door body 220 pivots relative to the box body 210, the first sliding shaft 2311 moves along the first sliding groove 2321, and the second sliding shaft 2312 moves along the second sliding groove 2322. Specifically, the first sliding shaft 2311 and the second sliding shaft 2312 can be provided on the first connecting member 231, and the first sliding groove 2321 and the second sliding groove 2322 can be provided on the second connecting member 232. Alternatively, the first sliding groove 2321 and the second sliding groove 2322 can be provided on the first connecting member 231, and the first sliding shaft 2311 and the second sliding shaft 2312 can be provided on the second connecting member 232. Alternatively, one of the first sliding shaft 2311 and the second sliding shaft 2312 may be disposed on the first connecting member 231 and the other may be disposed on the second connecting member 232, corresponding to one of the first sliding groove 2321 and the second sliding groove 2322 being disposed on the second connecting member 232 and the other being disposed on the first connecting member 231.

[0066] In this design, since the sliding groove and sliding shaft of the dual-axis hinge do not move in a circular motion, there is a gap between the sliding shaft and the sliding groove. The single-sided distance between the first sliding shaft 2311 and the groove wall of the first sliding groove 2321, and the single-sided distance between the second sliding shaft 2312 and the groove wall of the second sliding groove 2322, are less than or equal to 0.15mm. By reducing the clearance between the sliding shaft and the sliding groove, the wobbling that may occur when the sliding shaft moves along the sliding groove can be reduced.

[0067] During the contact between the elastic element 241 and the second contact section 2424, the first sliding shaft 2311 travels a distance greater than or equal to 6mm within the first sliding groove 2321, and the second sliding shaft 2312 travels a distance greater than or equal to 5mm within the second sliding groove 2322. As the first sliding shaft 2311 and the second sliding shaft 2312 move sufficiently within the first and second sliding grooves 2321 and 2322 respectively, the elastic element 241 gradually recovers its deformation, and its rebound force is gradually released. The door 220, under the rebound force, gradually rotates towards the housing 210 until it is closed. The door 220 rotates smoothly, avoiding any shaking or jerking during the closing process, reducing closing noise, and improving the user experience.

[0068] Furthermore, the elastic element 241 and the snap-fit ​​element 242 are respectively disposed on the first connector 231 and the second connector 232. The radius of the arc of the second contact segment 2424 is greater than or equal to 14mm, for example, 14mm, 16mm, or 18mm. Because the radius of the arc of the second contact segment 2424 is greater than or equal to 14mm, during the process of the door 220 rotating from the open state to the closed state, the second contact segment 2424 can gradually reduce the compression on the elastic element 241, the elastic element 241 gradually recovers its deformation, the rebound force of the elastic element 241 is gradually released, and the door 220 gradually rotates towards the housing 210 side under the rebound force until it is closed. The door 220 rotates smoothly, avoiding the shaking and jerking feeling during the closing process of the door 220, reducing the closing noise of the door 220, and improving the user experience.

[0069] In some embodiments, when the elastic member 241 contacts the first contact segment 2423, the angle between the tangent of the first contact segment 2423 at the contact point formed by the elastic member 241 and the tangent of the elastic member 241 at the contact point is less than or equal to 10°, for example, 10°, 8°, or 5°. Therefore, during the rotation of the door 220, when the door 220 rotates from the open state to the closed state, when the elastic member 241 begins to contact the first contact segment 2423, the first contact segment 2423 can gradually compress the elastic member 241, preventing the door 220 from shaking due to sudden deformation caused by the elastic member 241 being subjected to force when it first contacts the latching member 242. Furthermore, during the process of the door 220 rotating from the closed state to the open state, as the elastic element 241 moves from contacting the first contact segment 2423 to disengaging from the first contact segment 2423, the elastic element 241 can gradually release the rebound force, ensuring smooth rotation of the door 220 and avoiding shaking and jerking during the opening process. This reduces the noise of the door 220 rotation and improves the user experience.

[0071] Figure 12 This is a cross-sectional structural schematic diagram of another embodiment of the box device of this application; Figure 13 yes Figure 12 Enlarged view of section B.

[0072] Another embodiment of this application provides a cabinet device 300. The cabinet device 300 includes a cabinet 310, a door 320, a hinge assembly 330, and a self-locking assembly 340. The cabinet 310 has an internal receiving space with an opening. The door 320 is used for sealing or opening. The hinge assembly 330 is disposed on the pivot side of the cabinet 310, pivotally connecting the door 320 and the cabinet 310, thus achieving a rotational connection between the cabinet 310 and the door 320. The door 320 can be opened or closed relative to the cabinet 310 under the action of the hinge assembly 330. The hinge assembly 330 includes a first connector 331 and a second connector 332. The first connector 331 is disposed on one of the cabinet 310 and the door 320, and the second connector 332 is disposed on the other of the door 320 and the cabinet 310. The first connecting member 331 is provided with at least a sliding shaft 3310, and the second connecting member 332 is provided with at least a sliding groove 3320. During the pivotal rotation of the door body 320 relative to the housing 310, the sliding shaft 3310 moves along the sliding groove 3320. Specifically, the first connecting member 331 is provided on the door body 320, and the second connecting member 332 is provided on the housing 310; or the first connecting member 331 is provided on the door body 320, and the second connecting member 332 is provided on the housing 310. The self-locking assembly 340 includes an elastic member 341 and a locking member 342. During the rotation of the door body 320 from the open state to the closed state relative to the housing 310, the elastic member 341 and the locking member 342 transition from being separated from each other to being in contact with each other.

[0073] When the latching member 342 contacts and presses against the elastic member 341, the elastic deformation of the elastic member 341 under the action of the latching member 342 generates a rebound force. This rebound force can push the sliding shaft 3310 to move along the sliding groove 3320, and then converts into a self-locking force that pushes the door 320 to continue rotating towards the housing 310. The door 320 can gradually rotate towards the housing 310 until the door 320 is in the closed state. At the same time, the elastic deformation of the elastic member 341 under the action of the latching member 342 can generate a lateral pushing force. Since the sliding shaft 3310 moves in the sliding groove 3320, there is a certain fitting gap between the sliding shaft 3310 and the sliding groove 3320. This lateral pushing force generates a relative movement tendency along the radial direction of the sliding shaft 3310 between the sliding shaft 3310 and the groove wall of the sliding groove 3320, causing the sliding shaft 3310 to wobble in the sliding groove 3320, which in turn causes the door 320 to wobble and jerk during rotation. The enclosure device 300 is further provided with a force decomposition mechanism 350, which decomposes the lateral pushing force into a first force component and the gravity of the door 320 into a second force component. The first and second force components are opposite to each other. By providing the force decomposition mechanism 350, the component of gravity of the door 320 can be used to balance the radial component of the lateral pushing force generated by the elastic deformation of the elastic element 341 in the sliding shaft 3310, thereby allowing the sliding shaft 3310 to move smoothly in the sliding groove 3320, reducing or even avoiding the wobbling of the sliding shaft 3310 in the sliding groove 3320. The door 320 of the enclosure device 300 of this application rotates smoothly, avoiding the clearance fit problem caused by the design and manufacturing tolerances of the sliding shaft 3310 and the sliding groove 3320, reducing or even avoiding the wobbling and jerking feeling during the opening and closing of the door 320, reducing the noise of the door 320 opening and closing, and improving the user experience. The force disintegration mechanism 350 and self-locking component 340 of this application have simple structure, mature technology, are easy to manufacture, and have low cost.

[0074] It should be noted that the snap-fit ​​342 squeezes and compresses the elastic member 341. Part of the rebound force generated by the elastic deformation of the elastic member 341 forms a lateral pushing force to generate a relative movement tendency along the radial direction of the slide shaft 3310 between the slide shaft 3310 and the groove wall of the slide groove 3320. The other part of the rebound force generated by the elastic deformation of the elastic member 341 can push the slide shaft 3310 to move along the slide groove 3320.

[0075] In some embodiments, the force decomposition mechanism 350 includes a first contact portion 351 disposed on the slide shaft 3310 and a second contact portion 352 disposed on the groove wall of the slide groove 3320. The first contact portion 351 and the second contact portion 352 are in contact with each other, and at least one of the first contact portion 351 and the second contact portion 352 is inclined relative to the radial section of the slide shaft 3310, thereby decomposing the lateral pushing force and the gravity of the door body 320 into a first force component and a second force component along the inclined direction of at least one of the first contact portion 351 and the second contact portion 352 relative to the radial section of the slide shaft 3310. The second force component derived from the gravity of the door 320 can balance the first force component derived from the lateral pushing force of the elastic element 341, thereby allowing the sliding shaft 3310 to move smoothly within the sliding groove 3320, reducing or even eliminating the wobbling of the sliding shaft 3310 within the sliding groove 3320, thus making the door 320 rotate smoothly, reducing or even eliminating the wobbling and jerking sensation during the closing process of the door 320, reducing the noise of the door 320 opening and closing, and improving the user experience.

[0076] Specifically, the first contact portion 351 is located at the end of the slide shaft 3310 near the first connector 331, and the second contact portion 352 is located at the opening of the slide groove 3320; or, the first contact portion 351 is located at the end of the slide shaft 3310 away from the first connector 331, and the second contact portion 352 is located at the bottom of the slide groove 3320.

[0077] In some embodiments, the slide groove 3320 includes a first slide groove 3321 and a second slide groove 3322, and the slide shaft 3310 includes a first slide shaft 3311 and a second slide shaft 3312. A first contact portion 351 is disposed in at least one of the first slide shaft 3311 and the second slide shaft 3312, and a second contact portion 352 is correspondingly disposed in at least one of the first slide groove 3321 and the second slide groove 3322. Specifically, the first contact portion 351 and the second contact portion 352 are disposed in the first slide shaft 3311 and the first slide groove 3321; or, the first contact portion 351 and the second contact portion 352 are disposed in the second slide shaft 3312 and the second slide groove 3322; or, the first contact portion 351 is disposed in both the first slide shaft 3311 and the second slide shaft 3312, and correspondingly, the second contact portion 352 is disposed in both the first slide groove 3321 and the second slide groove 3322.

[0078] To increase the contact area of ​​the first contact portion 351 and the second contact portion 352 and reduce wear, the first contact portion 351 and the second contact portion 352 are inclined surfaces with the same inclination angle relative to the radial section of the slide shaft 3310. As a result, the first contact portion 351 and the second contact portion 352 are in surface contact. The increased contact area of ​​the first contact portion 351 and the second contact portion 352 can reduce the wear between the first contact portion 351 and the second contact portion 352 when the slide shaft 3310 moves in the slide groove 3320, improve the smoothness of the door body 320 movement, and increase the service life of the housing device 300.

[0079] Of course, in other embodiments, the first contact portion 351 and the second contact portion 352 can be inclined surfaces with different inclination angles relative to the radial cross-section of the slide shaft 3310, and the first contact portion 351 and the second contact portion 352 are in line contact. Alternatively, the first contact portion 351 and the second contact portion 352 can be curved surfaces that are inclined relative to the radial cross-section of the slide shaft 3310 and fit the shape, and the first contact portion 351 and the second contact portion 352 are in surface contact. Alternatively, the first contact portion 351 and the human contact portion can be curved surfaces that are inclined relative to the radial cross-section of the slide shaft 3310 and do not fit the shape completely, and the first contact portion 351 and the second contact portion 352 are in line contact. Alternatively, one of the first contact portion 351 and the second contact portion 352 can be an inclined surface or a curved surface that is inclined relative to the radial cross-section of the slide shaft 3310, and the other of the first contact portion 351 and the second contact portion 352 is a right angle, and the first contact portion 351 and the second contact portion 352 are in line contact. Various configurations of the first contact portion 351 and the second contact portion 352 can decompose the lateral pushing force and the gravity of the door body 320 into a first force component and a second force component along the inclined direction of at least one of the first contact portion 351 and the second contact portion 352 relative to the radial section of the slide shaft 3310. The second force component can balance the first force component, thereby allowing the slide shaft 3310 to move smoothly in the slide groove 3320, reducing or even avoiding the wobbling of the slide shaft 3310 in the slide groove 3320, thereby making the door body 320 rotate smoothly, reducing or even avoiding the wobbling and jerking sensation during the opening and closing of the door body 320, reducing the noise of the door body 320 opening and closing, and improving the user experience.

[0080] When the first contact portion 351 and the second contact portion 352 are inclined surfaces with the same inclination angle relative to the radial cross section of the sliding shaft 3310, in order to increase the second force component of the gravity relative to the inclination direction of the radial cross section of the sliding shaft 3310 and prevent the door body 320 from shaking in the vertical direction, the inclination angle of the first contact portion 351 and the second contact portion 352 relative to the radial cross section of the sliding shaft 3310 is greater than or equal to 45° and less than 90°, such as 45°, 60°, or 70°, etc., thereby increasing the second force component of the gravity relative to the inclination direction of the radial cross section of the sliding shaft 3310, so that the second force component is greater than or equal to the first force component, and preventing the door body 320 from shaking in the vertical direction.

[0081] In some embodiments, the width of the orthographic projection of the first contact portion 351 and the second contact portion 352 onto the radial section of the slide shaft 3310 is greater than or equal to 0.6 mm, for example, 0.6 mm, 0.75 mm, or 1 mm. By increasing the width of the orthographic projection of the first contact portion 351 and the second contact portion 352 onto the radial section of the slide shaft 3310, the contact area of ​​the first contact portion 351 and the second contact portion 352 can be increased, the pressure between the first contact portion 351 and the second contact portion 352 can be reduced, the wear between the first contact portion 351 and the second contact portion 352 can be reduced, the smoothness of the door 320 movement can be improved, and the service life of the housing device 300 can be increased.

[0082] In some embodiments, the height of the orthographic projection of the first contact portion 351 onto the axial section of the slide shaft 3310 is greater than the height of the orthographic projection of the second contact portion 352 onto the axial section of the slide shaft 3310. In this case, there is a height difference between the first contact portion 351 and the second contact portion 352, and the surface of the first contact portion 351 is larger than the second contact surface. When the slide shaft 3310 and the slide groove 3320 move relative to each other axially along the slide shaft 3310, the first contact portion 351 and the second contact portion 352 can always remain in contact, such that the lateral pushing force and the gravity of the door body 320 are decomposed into a first force component and a second force component along the inclined direction of at least one of the first contact portion 351 and the second contact portion 352 relative to the radial section of the slide shaft 3310. Thus, the second force component derived from the gravity of the door 320 can balance the first force component derived from the lateral pushing force of the elastic element 341, thereby allowing the sliding shaft 3310 to move smoothly within the sliding groove 3320, reducing or even eliminating the wobbling of the sliding shaft 3310 within the sliding groove 3320. This, in turn, makes the door 320 rotate smoothly, reducing or even eliminating the wobbling and jerking sensation during the opening and closing of the door 320, reducing the noise of the door 320 opening and closing, and improving the user experience. In addition, there is a height difference between the first contact portion 351 and the second contact portion 352, with the surface of the first contact portion 351 being larger than that of the second contact portion, which can improve the adaptability of the force decomposition mechanism 350 and offset certain manufacturing and installation errors.

[0083] When the elastic member 341 and the snap-fit ​​member 342 are separated from each other, the outer peripheral wall of the slide shaft 3310 and the groove wall of the slide groove 3320 have a radial gap A along the radial direction of the slide shaft 3310, and the contact area of ​​the first contact part 351 and the second contact part 352 has a movable allowance B along the axial direction of the slide shaft 3310. The movable allowance is greater than or equal to a first preset value. The first preset value is the product of the tangent of the tilt angle β of the first contact part 351 (tanβ) and the radial gap A, i.e., B≥A*tanβ. Thus, the sliding shaft 3310 and the sliding groove 3320 can fully contact each other through the first contact part 351 and the second contact part 352. The gravity of the door body 320 can be fully applied to the first contact part 351 and the second contact part 352. The second force component decomposed from the gravity of the door body 320 can fully balance the first force component decomposed from the lateral pushing force of the elastic element 341, so that the sliding shaft 3310 can move smoothly in the sliding groove 3320, avoiding the sliding shaft 3310 from shaking in the sliding groove 3320. This makes the door body 320 rotate smoothly, avoiding the shaking and jerking sensation during the opening and closing of the door body 320, reducing the noise of the door body 320 opening and closing, and improving the user experience.

[0084] Similarly, the free end of the sliding shaft 3310 has a certain gap with the bottom wall of the sliding groove 3320, so that the sliding shaft 3310 and the sliding groove 3320 can make contact completely through the first contact part 351 and the second contact part 352. The gravity of the door body 320 can be fully applied to the first contact part 351 and the second contact part 352. The second force component decomposed from the gravity of the door body 320 can fully balance the first force component decomposed from the lateral pushing force of the elastic element 341, so that the sliding shaft 3310 can move smoothly in the sliding groove 3320 and avoid the sliding shaft 3310 from shaking in the sliding groove 3320.

[0087] Another embodiment of this application provides a cabinet device 400. The cabinet device 400 includes a cabinet 410, a door 420, a hinge assembly 430, and a self-locking assembly 440. The cabinet 410 has an internal receiving space with an opening. The door 420 is used for sealing or opening. The hinge assembly 430 is disposed on the pivot side of the cabinet 410, pivotally connecting the door 420 and the cabinet 410, thus achieving a rotational connection between the cabinet 410 and the door 420. The door 420 can be opened or closed relative to the cabinet 410 under the action of the hinge assembly 430. The hinge assembly 430 includes a first connector 431 and a second connector 432. The first connector 431 is disposed on one of the cabinet 410 and the door 420, and the second connector 432 is disposed on the other of the door 420 and the cabinet 410. The first connecting member 431 is provided with at least a sliding shaft 4310, and the second connecting member 432 is provided with at least a sliding groove 4320. During the pivotal rotation of the door body 420 relative to the housing 410, the sliding shaft 4310 moves along the sliding groove 4320. Specifically, the first connecting member 431 is provided on the door body 420, and the second connecting member 432 is provided on the housing 410; or the first connecting member 431 is provided on the door body 420, and the second connecting member 432 is provided on the housing 410. The self-locking assembly 440 includes an elastic member 441 and a locking member 442. During the rotation of the door body 420 from the open state to the closed state relative to the housing 410, the elastic member 441 and the locking member 442 transition from being separated from each other to being in contact with each other.

[0088] When the latching member 442 contacts and presses against the elastic member 441, the elastic deformation of the elastic member 441 under the action of the latching member 442 generates a rebound force. This rebound force can push the sliding shaft 4310 to move along the sliding groove 4320, and then be converted into a self-locking force that pushes the door 420 to continue rotating towards the housing 410. The door 420 can gradually rotate towards the housing 410 until the door 420 is in the closed state. At the same time, the elastic deformation of the elastic member 441 under the action of the latching member 442 can generate a lateral pushing force. Since the sliding shaft 4310 moves in the sliding groove 4320, there is a certain fitting gap between the sliding shaft 4310 and the sliding groove 4320. This lateral pushing force generates a relative movement tendency along the radial direction of the sliding shaft 4310 between the sliding shaft 4310 and the groove wall of the sliding groove 4320, causing the sliding shaft 4310 to wobble in the sliding groove 4320, which in turn causes the door 420 to wobble and jerk during rotation. The slide groove 4320 includes a transition region 450. During at least partial contact between the elastic member 441 and the snap-fit ​​member 442, the slide shaft 4310 is located within the transition region 450. When the slide shaft 4310 is located within the transition region 450, there is a first radial gap between the slide shaft 4310 and the groove wall of the slide groove 4320. When the slide shaft 4310 is located in at least a portion of other groove segments outside the transition region 450, there is a second radial gap between the slide shaft 4310 and the groove wall of the slide groove 4320. The first radial gap is smaller than the second radial gap. By providing the transition region 450, when the slide shaft 4310 is located within the transition region 450, the first radial gap between the slide shaft 4310 and the groove wall of the slide groove 4320 is smaller than the second radial gap when the slide shaft 4310 is located in at least a portion of other groove segments. The transition region 450 can reduce or even prevent the slide shaft 4310 from sliding between the slide shaft 4310 and the groove wall of the slide groove 4320 under lateral pushing force. The door 420 of the enclosure device 400 of this application rotates smoothly, avoiding clearance fit problems caused by design and manufacturing tolerances of the sliding shaft 4310 and the sliding groove 4320, reducing or even eliminating the shaking and jerking sensation during the closing process of the door 420, reducing the closing noise of the door 420, and improving the user experience. The force decomposition mechanism and self-locking component 440 of this application have a simple structure, mature technology, are easy to manufacture, and are low in cost.

[0089] In some embodiments, the latching member 442 has a maximum protrusion 4421, which is the point on the latching member 442 where the elastic deformation of the elastic member 441 is maximized. At this point, the elastic member 441 reaches its maximum deformation, and the lateral pushing force generated by the elastic deformation of the elastic member 441 under the action of the latching member 442 reaches its maximum. At this point, the sliding shaft 4310 is more prone to wobbling within the sliding groove 4320. Specifically, at least within a predetermined contact range before and after the maximum protrusion 4421, the sliding shaft 4310 is located within the transition region 450, thereby reducing or even avoiding the wobbling of the sliding shaft 4310 within the sliding groove 4320 within the predetermined contact range before and after the maximum protrusion 4421. This reduces or even avoids the shaking and jerking sensation of the door 420 during opening and closing, reduces noise during the opening and closing of the door 420, and improves the user experience.

[0090] Specifically, during the process of the door 420 rotating from the open state to the closed state relative to the housing 410, the user pushes the door 420. When the door 420 rotates to a certain angle relative to the housing 410, the latching member 442 contacts and presses the elastic member 441. After the elastic member 441 passes the most protruding point 4421 of the latching member 442, the rebound force generated by the deformation of the elastic member 441 can be converted into a self-locking force that pushes the door 420 to continue rotating towards the housing 410. The door 420 gradually rotates towards the housing 410 under the rebound force. The door 420 continues to rotate towards the housing 410 until the magnetic strip of the housing 410 and the door 420 are attracted, and the door 420 is in the closed state. The user does not need to push the door 420 completely to close with the housing 410, but only closes the door 420 to a certain angle, and the door 420 can be automatically closed, ensuring the tightness of the closure of the door 420 and the housing 410 and improving the user's convenience. Since the sliding shaft 4310 is located within the transition area 450 within the predetermined contact range before and after the most prominent point 4421, the wobbling of the sliding shaft 4310 in the slide groove 4320 can be reduced or even avoided, thus reducing or even avoiding the shaking and jerking of the door 420 during the opening and closing process, reducing the noise of the door 420 during the opening and closing process, and improving the user experience.

[0091] Furthermore, when the elastic element 441 contacts the most prominent point 4421 of the latching element 442, the sliding shaft 4310 is located at the preset reference point C1 within the transition region 450. The width of the groove 4320 within the transition region 450 gradually widens from the preset reference point C1 to both sides. As the sliding shaft 4310 moves within the groove 4320, with the increase of the lateral pushing force generated by the elastic deformation of the elastic element 441 under the action of the latching element 442, the width of the groove 4320 within the transition region 450 gradually narrows at positions where radial displacement is more likely to occur. This can reduce or even avoid the wobbling of the sliding shaft 4310 within the groove 4320, reduce or even avoid the shaking and jerking of the door 420 during opening and closing, reduce noise during the opening and closing of the door 420, and improve the user experience. It should be noted that the first direction is the direction perpendicular to the movement direction of the slide shaft 4310 within the slide groove 4320, and the distance between the intersection of the first direction and the two side walls of the slide groove 4320 is the width of the slide groove 4320. For example, the width of the slide groove 4320 in other areas is 6mm. After setting the transition area 450, the width of the slide groove 4320 at the preset reference point C1 is 5.8mm. The width of the slide groove 4320 within the transition area 450 gradually widens from the preset reference point C1 to both sides.

[0092] To effectively prevent the door 420 from shaking or jerking during opening and closing, when the sliding shaft 4310 is located within the transition area 450, an interference fit is formed between the sliding shaft 4310 and the slide groove 4320. This prevents the sliding shaft 4310 from shaking within the slide groove 4320, thus avoiding shaking and jerking of the door 420 during opening and closing and reducing noise during the door's operation. When the sliding shaft 4310 is located in other groove sections, a clearance fit is formed between the sliding shaft 4310 and the slide groove 4320, facilitating smooth movement of the sliding shaft 4310 within other slide grooves 4320 and improving the smoothness of the door 420's rotation.

[0093] In some embodiments, at least one side wall of the slide groove 4320 in the transition region 450 has an elastic segment 453, which provides radial elastic support for the slide shaft 4310 located within the transition region 450. Specifically, elastic segments 453 are provided on both sides of the slide groove 4320 in the transition region 450. When the slide shaft 4310 moves along the slide groove 4320, it compresses the elastic segments 453 on both sides, and the rebound force of the elastic segments 453 on both sides provides effective radial elastic support for the slide shaft 4310 located within the transition region 450. The rebound force of the elastic segments 453 on both sides of the slide groove can effectively push the slide shaft 4310, causing the door 420 to rotate towards the housing 410.

[0094] In this embodiment, the elastic segment 453 is an elastic layer attached to the wall of the first groove 4321. The elastic layer can be made of a resilient material, such as polyoxymethylene (POM). In other embodiments, the elastic segment 453 is formed by the wall of the resilient groove 4320. The wall of the groove 4320 is made of a resilient material, such as POM. Further, the second connector 432 is formed of POM, such as POM.

[0095] In some embodiments, when the elastic member 441 contacts the most protruding point 4421 of the snap-fit ​​member 442, the slide shaft 4310 is located at a preset reference point C1 within the transition region 450. The elastic segment 453 is an elastic layer attached to the groove wall of the first slide groove 4321. The thickness of the elastic segment 453 along the width direction of the slide groove 4320 gradually decreases from the preset reference point C1 to both sides, so that the interference that the elastic segment 453 can provide to the slide shaft 4310 gradually decreases from the preset reference point C1 to both sides, and the width of the slide groove 4320 within the transition region 450 gradually widens from the preset reference point C1 to both sides, which can prevent the slide shaft 4310 from shaking within the slide groove 4320, avoid the door 420 from shaking and jerking during the opening and closing process, and reduce the noise during the opening and closing process of the door 420.

[0096] Specifically, at the preset reference point C1, the interference fit between the sliding shaft 4310 and the sliding groove 4320 is 0-1mm, such as 0mm, 0.5mm, or 1mm. When the interference fit between the sliding shaft 4310 and the sliding groove 4320 is 0mm, the sliding shaft 4310 and the sliding groove 4320 are in contact at the preset reference point C1 but without interaction force, which can reduce the shaking of the sliding shaft 4310 in the sliding groove 4320. The interference fit between the sliding shaft 4310 and the sliding groove 4320 can be adjusted according to the elastic coefficient of the elastic layer and the gap between the sliding shaft 4310 and the groove wall of the sliding groove 4320.

[0097] In some embodiments, the slide 4320 includes a first slide 4321 and a second slide 4322, the slide shaft 4310 includes a first slide shaft 4311 and a second slide shaft 4312, and the transition region 450 includes a first transition region 451 located in the first slide 4321 and a second transition region 452 located in the second slide 4322. When the door body 420 pivots relative to the box body 410, the first slide shaft 4311 moves along the first slide 4321, and the second slide shaft 4312 moves along the second slide 4322. The first slide shaft 4311 and the second slide shaft 4312 simultaneously enter and leave the first transition region 451 and the second transition region 452, respectively. Thus, the force exerted by the first transition region 451 on the first sliding shaft 4311 can be reduced or even avoided, resulting in the sliding between the first sliding shaft 4311 and the groove wall of the first sliding groove 4321 under the lateral pushing force. Similarly, the force exerted by the second transition region 452 on the second sliding shaft 4312 can be reduced or even avoided, resulting in the sliding between the second sliding shaft 4312 and the groove wall of the second sliding groove 4322 under the lateral pushing force. The simultaneous entry and exit of the first sliding shaft 4311 and the second sliding shaft 4312 into and from the first transition region 451 and the second transition region 452, respectively, allows the door 420 to rotate more smoothly, reducing or even avoiding the shaking and jerking sensation during the closing process of the door 420, reducing the closing noise of the door 420, and improving the user experience.

[0098] The parameters of the second transition region 452 are set similarly to those of the first transition region 451, and will not be described again here. Of course, in other embodiments, the first transition region 451 may only be provided within the first groove 4321.

[0099] Specifically, the first sliding shaft 4311 and the second sliding shaft 4312 can be disposed on the first connecting member 431, and the first sliding groove 4321 and the second sliding groove 4322 can be disposed on the second connecting member 432. Alternatively, the first sliding groove 4321 and the second sliding groove 4322 can be disposed on the first connecting member 431, and the first sliding shaft 4311 and the second sliding shaft 4312 can be disposed on the second connecting member 432. Alternatively, one of the first sliding shaft 4311 and the second sliding shaft 4312 can be disposed on the first connecting member 431, and the other can be disposed on the second connecting member 432, and the first sliding groove 4321 and the second sliding groove 4322 can be disposed on the second connecting member 432, and the other can be disposed on the first connecting member 431.

[0100] The housing device 400 of this application may employ a single-axis or dual-axis hinge assembly 430, or a three-axis or more hinge assembly 430.

[0101] Please see Figures 18 to 20 , Figure 18This is a partial structural schematic diagram of another embodiment of the housing device of this application, in which the housing device is in the open state; Figure 19 This is a partial structural schematic diagram of another embodiment of the housing device of this application, in which the housing device is in a closed state; Figure 20 This is a structural schematic diagram of the second connector of another embodiment of the housing device of this application.

[0102] Another embodiment of this application provides a cabinet device 500. The cabinet device 500 includes a cabinet 510, a door 520, a hinge assembly 530, and a self-locking assembly 540. The cabinet 510 has an internal receiving space with an opening. The door 520 is used for sealing or opening. The hinge assembly 530 is disposed on the pivot side of the cabinet 510, pivotally connecting the door 520 and the cabinet 510, thus achieving a rotational connection between the cabinet 510 and the door 520. The door 520 can be opened or closed relative to the cabinet 510 under the action of the hinge assembly 530. The hinge assembly 530 includes a first connector 531 and a second connector 532. The first connector 531 is disposed on one of the cabinet 510 and the door 520, and the second connector 532 is disposed on the other of the door 520 and the cabinet 510. The first connecting member 531 is provided with at least a sliding shaft 5310, and the second connecting member 532 is provided with at least a sliding groove 5320. During the pivotal rotation of the door body 520 relative to the housing 510, the sliding shaft 5310 moves along the sliding groove 5320. Specifically, the first connecting member 531 is provided on the door body 520, and the second connecting member 532 is provided on the housing 510; or the first connecting member 531 is provided on the door body 520, and the second connecting member 532 is provided on the housing 510. The self-locking assembly 540 includes an elastic member 541 and a locking member 542. During the rotation of the door body 520 from the open state to the closed state relative to the housing 510, the elastic member 541 and the locking member 542 transition from being separated from each other to being in contact with each other. The latching member 542 has a maximum protrusion 5421 and a locking position 5422. The maximum protrusion 5421 is the position on the latching member 542 that causes the elastic member 541 to have the greatest elastic deformation. When the door 520 rotates from the open state to the closed state relative to the box 510, the elastic member 541 and the latching member 542 come into contact with each other. After the elastic member 541 passes the maximum protrusion 5421 of the latching member 542, it enters the locking position 5422, thereby locking the door 520 in the closed state.

[0103] Before the elastic member 541 and the snap-fit ​​member 542 make contact, the sliding shaft 5310 moves within the first section D1 of the slide groove 5320. Before the elastic member 541 and the snap-fit ​​member 542 make contact and reach the most prominent point 5421, the sliding shaft 5310 moves within the second section D2 of the slide groove 5320. During the process of the elastic member 541 moving from the most prominent point 5421 to the locking position 5422, the sliding shaft 5310 moves within the third section D3 of the slide groove 5320. The width of at least a portion of the third section D3 of the slide groove 5320 near the locking position 5422 is greater than the width of the first section D1 of the slide groove 5320. When the door 520 is rotated to a near-closed state, i.e., when the sliding shaft 5310 is located in the third section D3 of the slide groove 5320, since the width of at least part of the third section D3 corresponding to the locking position 5422 of the elastic element 541 is greater than the width of the first section D1 of the slide groove 5320, the fit clearance between the sliding shaft 5310 and the slide groove 5320 is larger, and the friction between the sliding shaft 5310 and the slide groove 5320 is smaller, thus avoiding affecting the rebound force of the elastic element 541, effectively improving the smoothness of closing the door at a small angle, and improving the quality of the door device.

[0104] Specifically, during the process of the door 520 rotating from the open state to the closed state relative to the housing 510, the user pushes the door 520. When the door 520 rotates to a certain angle relative to the housing 510, the latching member 542 contacts and squeezes the elastic member 541. After the elastic member 541 passes the most protruding point 5421 of the latching member 542, the rebound force generated by the deformation of the elastic member 541 can be converted into a self-locking force that pushes the door 520 to continue rotating towards the housing 510. The door 520 gradually rotates towards the housing 510 due to the rebound force. The door 520 continues to rotate towards the housing 510 until the magnetic strip of the housing 510 and the door 520 are attracted, and then the door 520 is in the closed state. However, after the elastic element 541 passes the most protruding point 5421 of the snap-fit ​​element 542, the door 520 needs to be closed automatically by the rebound force of the elastic element 541 without external force. At this time, the sliding shaft 5310 is located in the third section D3 of the sliding groove 5320. If the door 520 in this area cannot be effectively closed, there will be gaps between the door seal and the door 520. Since the closing angle is already small, the door opening alarm function designed on the refrigerator has determined that the door 520 is closed and no longer provides an alarm function. During long-term use, the door 520 will suffer from severe cold leakage, condensation, and ice formation. In this application, when the sliding shaft 5310 is located in the third interval D3 of the sliding groove 5320, since the width of at least a portion of the third interval D3 corresponding to the locking position 5422 of the elastic element 541 is greater than the width of the first interval D1 of the sliding groove 5320, the fitting clearance between the sliding shaft 5310 and the sliding groove 5320 is larger, and the friction between the sliding shaft 5310 and the sliding groove 5320 is smaller. This avoids affecting the rebound force of the elastic element 541, effectively improving the smoothness of closing the door at small angles, improving the quality of the door device, and avoiding a series of problems caused by the door 520 not being closed. In the cabinet device 500 of this application, the user does not need to push the door 520 completely to close with the cabinet 510. Instead, after closing the door 520 to a certain angle, the door 520 can be automatically closed, ensuring the tightness of the closure between the door 520 and the cabinet 510, and improving the user's convenience.

[0105] In some embodiments, the width of the third interval D3 gradually widens in the direction away from the second interval D2, thereby gradually increasing the mating clearance between the sliding shaft 5310 and the sliding groove 5320 in the third interval D3 as the elastic member 541 approaches the locking position 5422 from the most prominent point 5421. On the one hand, this gradually reduces the friction between the sliding shaft 5310 and the sliding groove 5320, avoiding affecting the rebound force of the elastic member 541, effectively improving the smoothness of closing the door at small angles, and ensuring that the door 520 is closed on the housing 510. On the other hand, the gradual widening of the width of the third interval D3 in the direction away from the second interval D2 can reduce or even avoid the swaying of the sliding shaft 5310 in the sliding groove 5320 when the elastic member 541 passes the most prominent point 5421, reducing or even avoiding the swaying and jerking of the door 520 during the opening and closing process, reducing noise during the opening and closing process of the door 520, and improving the user experience.

[0106] In some embodiments, the third interval D3 includes a first sub-interval and a second sub-interval. During the process of the elastic member 541 moving from its most prominent point 5421 to its locking position 5422, the sliding shaft 5310 passes through the first sub-interval and the second sub-interval successively. The first sub-interval is closer to the second interval D2, and the second sub-interval is farther from the second interval D2. When the sliding shaft 5310 is in the first sub-interval, the elastic member has just passed the most prominent point 5421 of the latching member 542. To reduce or even avoid the wobbling of the sliding shaft 5310 within the slide groove 5320, the width of the first sub-interval is smaller than the width of the first interval D1 of the slide groove 5320, thus reducing or even avoiding any wobbling or jerking sensation during the opening and closing of the door body 520, and reducing noise during the opening and closing process of the door body 520. When the sliding shaft 5310 is located in the second sub-section, the elastic element 541 approaches the locking position 5422 of the snap-fit ​​element 542. In order to reduce the friction between the sliding shaft 5310 and the slide groove 5320, the width of the second sub-section is greater than the width of the first section D1 of the slide groove 5320. This can effectively reduce the friction between the sliding shaft 5310 and the slide groove 5320, avoid affecting the rebound force of the elastic element 541, effectively improve the smoothness of closing the door at a small angle, and ensure that the door 520 is closed on the housing 510.

[0107] In some embodiments, the length of the third interval D3 is greater than the length of the second interval D2, so that both the first and second sub-intervals of the third interval D3 have sufficient length. When the elastic element 541 just passes the most protruding point 5421 of the latching element 542, the first sub-interval can be set to a certain length to accommodate the release of the elastic force of the elastic element 541, effectively reducing or even avoiding the shaking of the sliding shaft 5310 in the sliding groove 5320, reducing or even avoiding the shaking and jerking of the door 520 during the opening and closing process, and reducing the noise of the door 520 during the opening and closing process; when the elastic element 541 approaches the locking position 5422 of the latching element 542, the second sub-interval can be set to a certain length to increase the sliding gap between the sliding shaft 5310 and the sliding groove 5320, effectively reducing the friction between the sliding shaft 5310 and the sliding groove 5320, effectively improving the smoothness of closing at small angles, and ensuring that the door 520 is closed on the housing 510. Specifically, the length of the third interval D3 is 8mm, and the length of the second interval D2 is 4.5mm.

[0108] When the elastic element 541 and the latching element 542 transition from being separated to being in contact with each other, and the elastic element 541 approaches the most protruding point 5421 of the latching element 542, the elastic force of the elastic element 541 is relatively large. In order to reduce or even avoid the shaking of the sliding shaft 5310 in the sliding groove 5320, at least a portion of the width of the second section D2 of the sliding groove 5320 near the most protruding point 5421 is smaller than the width of the first section D1 of the sliding groove 5320. This reduces or even avoids the shaking of the sliding shaft 5310 in the sliding groove 5320, reduces or even avoids the shaking and jerking of the door 520 during the opening and closing process, reduces the noise of the door 520 during the opening and closing process, and improves the user experience.

[0109] When the slide shaft 5310 is located in the first interval D1 of the slide groove 5320, and in at least a portion of the third interval D3 of the slide groove 5320 near the locking position 5422, the elastic member 541 does not contact the locking member 542, or the interaction force between the elastic member 541 and the locking member 542 is very small, and the slide shaft 5310 is not prone to shaking when moving within the slide groove 5320. To improve the smoothness of the movement of the slide shaft 5310 within the slide groove 5320, the slide groove... The width of the first section D1 of 5320 and the width of at least a portion of the third section D3 of the slide groove 5320 near the locking position 5422 are set such that the slide groove 5320 and the slide shaft 5310 are fitted with a radial clearance along the slide shaft 5310, thereby reducing the friction between the slide shaft 5310 and the slide groove 5320, improving the smoothness of the slide shaft 5310 moving in the slide groove 5320, ensuring smooth rotation of the door body 520 relative to the box body 510, and improving the quality of the box body device 500.

[0110] When the sliding shaft 5310 is located in at least a portion of the second section D2 of the slide groove 5320 near the most prominent point 5421, the elastic force of the elastic element 541 is relatively large. In order to reduce or even avoid the shaking of the sliding shaft 5310 in the slide groove 5320, the width of at least a portion of the second section D2 of the slide groove 5320 near the most prominent point 5421 is set such that the slide groove 5320 and the sliding shaft 5310 are radially interference-fitted, thereby reducing or even avoiding the shaking of the sliding shaft 5310 in the slide groove 5320, reducing or even avoiding the shaking and jerking of the door 520 during the opening and closing process, reducing the noise of the door 520 during the opening and closing process, and improving the user experience.

[0111] When the sliding shaft 5310 is located in at least a portion of the third interval D3 of the slide groove 5320 near the most convex point 5421, the elastic force of the elastic element 541 is relatively large. In order to reduce or even avoid the shaking of the sliding shaft 5310 in the slide groove 5320, the width of at least a portion of the third interval D3 of the slide groove 5320 near the most convex point 5421 is set such that the slide groove 5320 and the sliding shaft 5310 are radially interference-fitted, thereby reducing or even avoiding the shaking of the sliding shaft 5310 in the slide groove 5320, reducing or even avoiding the shaking and jerking of the door 520 during the opening and closing process, reducing the noise of the door 520 during the opening and closing process, and improving the user experience.

[0112] In some embodiments, the portion of the second section D2 of the slide groove 5320 that radially interferes with the slide shaft 5310 has an elastic segment. This elastic segment provides radial elastic support to the slide shaft 5310 located within this section. Specifically, elastic segments are correspondingly provided on both sides of the slide groove 5320 within this section. The elastic segment is an elastic layer attached to the wall of the slide groove 5320, and the elastic layer can be made of a resilient material, such as polyoxymethylene (POM). In other embodiments, the elastic segment is formed by the resilient wall of the slide groove 5320. The wall of the slide groove 5320 is made of a resilient material, such as POM. Further, the second connector 532 is formed of POM, for example, POM.

[0113] Similarly, the portion of the slide shaft 5310 in the third section D3 of the slide groove 5320 that radially interferes with the slide shaft 5310 has an elastic section. This elastic section provides radial elastic support to the slide shaft 5310 located within this section. Specifically, elastic sections are correspondingly provided on both sides of the slide groove 5320 within this section. The elastic section is an elastic layer attached to the wall of the slide groove 5320, and the elastic layer can be made of a resilient material, such as polyoxymethylene (POM). In other embodiments, the elastic section is formed by the resilient wall of the slide groove 5320. The wall of the slide groove 5320 is made of a resilient material, such as POM. Further, the second connector 532 is formed of POM, for example, POM.

[0114] In addition, the width of the second interval D2 gradually increases in the direction away from the third interval D3. When the elastic element 541 and the snap-fit ​​element 542 transition from being separated to being in contact with each other, and the elastic element 541 approaches the most protruding point 5421 of the snap-fit ​​element 542, the rebound force of the elastic element 541 gradually increases. In order to reduce or even avoid the shaking of the slide shaft 5310 in the slide groove 5320, the width of the second interval D2 gradually increases in the direction away from the third interval D3. That is, the fit gap between the slide shaft 5310 and the slide groove 5320 in the second interval D2 gradually decreases in the direction closer to the third interval D3. This can reduce or even avoid the shaking of the slide shaft 5310 in the slide groove 5320, reduce or even avoid the shaking and jerking of the door 520 during the opening and closing process, reduce the noise of the door 520 during the opening and closing process, and improve the user experience.

[0115] Furthermore, when the sliding shaft 5310 is located in the first section D1 of the slide groove 5320, there is a first radial clearance between the sliding shaft 5310 and the slide groove 5320. When the sliding shaft 5310 is located in at least a portion of the third section D3 of the slide groove 5320 near the locking position 5422, there is a second radial clearance between the sliding shaft 5310 and the slide groove 5320. The difference between the second radial clearance and the first radial clearance is not less than 0.15mm, for example, 0.15mm, 0.3mm, 0.45mm, etc. By setting a sufficient difference between the second radial clearance and the first radial clearance, when the sliding shaft 5310 is located in at least a portion of the third section D3 of the slide groove 5320 near the locking position 5422, the fit clearance between the sliding shaft 5310 and the slide groove 5320 is sufficiently increased, the friction between the sliding shaft 5310 and the slide groove 5320 is reduced, the smoothness of closing the door is effectively improved, and the quality of the door device is enhanced.

[0116] Specifically, the diameter of the slide shaft 5310 is 5.95 mm. When the slide shaft 5310 is located in the first section D1 of the slide groove 5320, the width of the slide groove 5320 is 6.1 mm, the force required to close the door is approximately 6 N, and the first radial clearance is 0.15 mm. When the elastic member 541 contacts the most prominent point 5421 of the snap-fit ​​member 542, the slide shaft 5310 is located at the junction of the second section D2 and the third section D3. At this point, the width of the slide groove 5320 is the smallest, at 5.8 mm, and the force required to close the door is approximately 12 N. When the elastic element 541 passes the most protruding point 5421 of the snap-fit ​​element 542, without external force, the door 520 closes automatically by the rebound force of the elastic element 541. When the slide shaft 5310 moves to at least part of the third section D3 of the slide groove 5320 near the locking position 5422, the width of the slide groove 5320 is 6.25mm and the second radial clearance is 0.3mm. At this time, the difference between the second radial clearance and the first radial clearance is 0.15mm.

[0117] In some embodiments, the slide 5320 includes a first slide 5321 and a second slide 5322, and the slide shaft 5310 includes a first slide shaft 5311 and a second slide shaft 5312. When the door body 520 pivots relative to the housing 510, the first slide shaft 5311 moves along the first slide 5321, and the second slide shaft 5312 moves along the second slide 5322. The first slide 5321 includes the first interval D1, the second interval D2, and the third interval D3 described above. If the first slide shaft 5311 moves in the third interval D3 of the first slide 5321, and the second slide shaft 5312 has already been positioned and rotated within the second slide 5322, the width of the groove segment of the second slide 5322 when the elastic member 541 is close to the locking position 5422 can be set to be greater than the width of other groove segments, which facilitates the rotation of the second slide shaft 5312 within the second slide 5322. When the first sliding shaft 5311 moves in the third section D3 of the first sliding groove 5321, the second sliding shaft 5312 moves along the second sliding groove 5322. The second sliding groove 5322 can also be configured to include the first section D1, the second section D2, and the third section D3 mentioned above. The fit clearance between the sliding shaft 5310 and the sliding groove 5320 is relatively large, and the friction between the sliding shaft 5310 and the sliding groove 5320 is relatively small, which avoids affecting the rebound force of the elastic element 541, effectively improving the smoothness of closing the door at small angles and improving the quality of the door device.

[0118] Specifically, the first sliding shaft 5311 and the second sliding shaft 5312 can be disposed on the first connecting member 531, and the first sliding groove 5321 and the second sliding groove 5322 can be disposed on the second connecting member 532. Alternatively, the first sliding groove 5321 and the second sliding groove 5322 can be disposed on the first connecting member 531, and the first sliding shaft 5311 and the second sliding shaft 5312 can be disposed on the second connecting member 532. Alternatively, one of the first sliding shaft 5311 and the second sliding shaft 5312 can be disposed on the first connecting member 531, and the other can be disposed on the second connecting member 532, and the first sliding groove 5321 and the second sliding groove 5322 can be disposed on the second connecting member 532, and the other can be disposed on the first connecting member 531.
