Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of refrigerators with hinge structures, and in particular to a hinge structure and a refrigerator. BACKGROUND

[0002] With the pursuit of aesthetics and space utilization in modern kitchens, flat-embedded refrigerators have become mainstream products in the mid-to-high-end market because they can be flush with the cabinets and achieve visual integration. The performance of the hinge system directly determines the assembly process, user experience, and maintenance convenience.

[0003] To meet the core setting requirement of flat-embedded refrigerators, i.e., the outer side does not protrude beyond the side wall of the cabinet when the door is opened, to avoid interference with the cabinet and achieve "zero protrusion", existing hinges mostly adopt concealed, translational opening, or small-radius rotating structures. However, manufacturers generally pursue high volume rates, i.e., increasing the internal storage space under the same external dimensions, which has caused a series of structural problems. First, the door body needs to be thickened with a foamed layer to ensure thermal insulation performance, resulting in a door body thickness exceeding the side wall of the cabinet. Second, when the door is closed, the thick inner wall of the door covers the mouth area of the inner tank of the cabinet, making the cooperation area between the door seal and the mouth area narrow. Third, during the production and assembly, after-sales maintenance, or user cleaning process, when the internal accessories such as glass shelves and box frames are disassembled, the blocked mouth of the tank limits the operation space, and tools cannot be inserted, which not only reduces the disassembly and assembly efficiency, but also easily damages the components.

[0004] The existing hinge has obvious defects: most of them are fixed or can only be adjusted slightly, and the relative position between the door body and the cabinet cannot be dynamically changed after the whole machine is assembled. SUMMARY

[0005] The present disclosure provides a hinge structure and a refrigerator to solve the technical problem that most of the existing technologies are fixed or can only be adjusted slightly, and the relative position between the door body and the cabinet cannot be dynamically changed after the whole machine is assembled.

[0006] The hinge structure provided by the embodiments of the present disclosure comprises a base and a mounting sliding block. The base comprises a first mounting portion and a limiting boss arranged on the surface of the first mounting portion. The limiting boss has a sliding groove portion arranged along the length direction of the limiting boss. The sliding groove portion has a first limiting structure arranged at a first limiting position and a second limiting structure arranged at a second limiting position. The first limiting position and the second limiting position are arranged at intervals. The mounting sliding block comprises a second mounting portion and a sliding rail portion arranged on one side of the second mounting portion. The sliding rail portion is used for sliding cooperation with the sliding groove portion. The sliding rail portion is configured to move in the sliding groove portion and switch between the first limiting position and the second limiting position, so that the second mounting portion moves with the sliding rail portion, and the installation position of the second mounting portion relative to the first mounting portion is changed.

[0007] The first limiting structure is configured as a first limiting hole, the second limiting structure is configured as a second limiting hole, and the first limiting hole is arranged separately from the second limiting hole; the slide rail part has a third limiting hole; The hinge structure further includes a limiting column, the limiting column is mounted in the third limiting hole, and the limiting column is configured to be inserted into the first limiting hole in a first position and to be inserted into the second limiting hole in a second position, so as to lock the mounting slide block in the first limiting hole or the second limiting hole.

[0008] The hinge structure further includes an elastic member, the elastic member is sleeved on the outer periphery of the limiting column, and the elastic member is used to support the limiting column, the limiting column is configured to be locked between the first limiting hole and the third limiting hole under the upward elastic force of the elastic member, or The limiting column is configured to be locked between the second limiting hole and the third limiting hole under the upward elastic force of the elastic member.

[0009] The limiting column is configured to be moved downward from the first limiting hole into the slide groove part, so that the limiting boss and the slide rail part lose axial limiting, the slide rail part is configured to continue to move relative to the slide groove part until the limiting column is inserted into the second limiting hole, so as to lock the mounting slide block in the second limiting hole of the limiting boss.

[0010] The elastic member is mounted between the limiting column and the third limiting hole, so that the elastic potential energy generated by the elastic member directly acts on the limiting column.

[0011] The outer periphery of the limiting column protrudes against a table surface, the third limiting hole has a bearing plane inside, one end of the elastic member abuts against the abutting table surface, and the other end of the elastic member abuts against the bearing plane, so that the elastic force of the elastic member acts upward on the limiting.

[0012] The slide groove part is configured as a cross-shaped through slot, and the slide groove part forms an opening at the bottom surface of the limiting boss; the slide rail part is configured as an I-shaped structure, the upper region of the I-shaped structure is arranged in the slide groove part, and the lower region of the I-shaped structure protrudes from the bottom surface of the limiting boss to form a push sub-portion that is convenient to move.

[0013] The second mounting part is configured as a first plane, the first mounting part is configured as a first vertical surface, and the first plane is arranged perpendicularly to the first vertical surface.

[0014] The hinge structure further includes two hinge shafts, and the second mounting part has two separately disposed shaft holes, with one hinge shaft corresponding to one shaft hole.

[0015] This disclosure also provides a refrigerator, which includes a cabinet and a door. The door is located in the vent area of ​​the cabinet. The refrigerator also includes the aforementioned hinge structure. The first mounting part is connected to one side of the cabinet, and the second mounting part is connected to one side of the door. The door is configured to move relative to the cabinet by following the movement of the slide rail, so that the door avoids covering the vent area of ​​the cabinet.

[0016] The technical solutions provided in this disclosure have the following advantages compared with the prior art: The hinge structure and refrigerator provided in this embodiment, from the perspective of the adaptability of the hinge structure itself in limiting state, can achieve the following usage effects through the sliding cooperation between the slide rail and the slide groove and the setting of two limiting positions: When the slide rail is in the first limiting position, the relative position of the mounting slider and the base is fixed, which can ensure that the two components connected by the hinge are stable in position during normal use, avoid relative displacement due to vibration or external force, and ensure connection reliability; When the slide rail moves from the first limiting position to the second limiting position, the mounting slider moves synchronously with the slide rail, which can change the installation position of the second mounting part relative to the first mounting part, and the second limiting position can form a stable limit on the slide rail, so that the adjusted position remains fixed.

[0017] Specifically, the slide groove is provided with a first limiting structure corresponding to the first limiting position. In the first application scenario, the slide rail and the first limiting structure are adapted to each other, directly restricting the displacement of the slide rail within the slide groove. In the second application scenario, the slide groove is provided with a second limiting structure corresponding to the second limiting position. When the slide rail slides along the slide groove to the second limiting position, the slide rail and the second limiting structure are adapted to each other, directly restricting the displacement of the slide rail within the slide groove. Combined with the interval between the two limiting structures, the installation position of the mounting slider relative to the base can be changed, that is, it breaks through the limitation that the position of traditional fixed hinges cannot be adjusted.

DETAILED DESCRIPTION

[0023] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present disclosure.

[0024] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present disclosure. For the purpose of simplicity, the components and arrangements of the various examples are shown in the following description. These are, of course, merely examples and are not intended to limit the disclosure. Moreover, the disclosure can be practiced with less than all these components-— for example, not having one or more of the benefits and / or advantages described below. Also, the disclosure can be along with other components, e.g., not expressly listed in the following description. Additionally, the disclosure can be implemented in a wide variety of environments and / or architectures.

[0025] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptions used in this text have been explained accordingly.

[0026] The hinge structure provided in this embodiment addresses the obvious defects of existing hinges: most are fixed or can only be finely adjusted, and the relative position of the door and the box cannot be dynamically changed after the whole machine is assembled. The hinge structure is adjusted to be adaptable and movable in fixed installation scenarios, thereby adjusting the relative movement of the door and the box in actual installation scenarios.

[0027] refer to Figures 1-4 This disclosure provides a hinge structure 001 and a refrigerator having the same. The hinge structure 001 includes a base 1 and a mounting slider 2. The base 1 includes a first mounting portion 11 and a limiting boss 12 disposed on the surface of the first mounting portion 11. The limiting boss 12 has a sliding groove portion 121 extending along its own length direction. The sliding groove portion 121 has a first limiting structure disposed at a first limiting position A and a second limiting structure disposed at a second limiting position B. The first limiting position A and the second limiting position B are spaced apart. The mounting slider 2 includes a second mounting portion 21 and a slide rail portion 22 disposed on one side of the second mounting portion 21. The slide rail portion 22 is used to slide and engage with the sliding groove portion 121. The slide rail portion 22 is configured to move in the sliding groove portion 121 and switch between the first limiting position A and the second limiting position B, so that the second mounting portion 21 moves with the slide rail portion 22, thereby changing the mounting position of the second mounting portion 21 relative to the first mounting portion 11.

[0028] For example, the first mounting part 11 refers to the structure on the base 1 for fixing the hinge to the refrigerator body 7, for example, referring to Figure 1The base 1 and the fixing holes provided on the base 1, the first mounting part 11 can be provided with multiple fixing holes that penetrate the base 1, and the base 1 can be firmly installed on the side or top / bottom frame of the refrigerator body 7 by fasteners such as screws and rivets passing through the fixing holes, so as to achieve a stable connection between the hinge and the body 7.

[0029] For example, the second mounting part 21 refers to the structure on the mounting slider 2 for connecting the refrigerator door body 6, for example, in combination with Figure 1 The middle slider and the hinge shaft 5 mounted on the slider are provided. The second mounting part 21 can be provided with a shaft hole 211 for mounting the hinge shaft 5. The hinge shaft 5 is riveted or snapped into the shaft hole 211. Then, the hinge shaft 5 cooperates with the door hinge seat of the door body 6 to realize the linkage connection between the mounting slider 2 and the door body 6, ensuring that the door body 6 moves synchronously with the mounting slider 2.

[0030] For example, the limiting boss 12 refers to a block-shaped or strip-shaped structure protruding on the surface of the first mounting portion 11 of the base 1. For example, referring to... Figure 1 The raised portion of the middle base 1 and the raised area where the third limiting hole 221 is located, the limiting boss 12 extends perpendicularly to the surface of the first mounting part 11. Its function is to provide a mounting carrier for the sliding groove part 121, avoid the insufficient structural strength caused by the sliding groove part 121 being directly opened on the first mounting part 11, and at the same time, the raised shape facilitates a precise fit with the slide rail part 22.

[0031] For example, the groove 121 refers to a groove-shaped structure that extends along the length direction of the limiting boss 12. For example, it can be understood as a long groove opened on the limiting boss 12. The cross-sectional shape of the groove can be set to any one of rectangular, T-shaped, dovetail, or cross-shaped, etc. Its length direction is consistent with the opening / closing direction of the refrigerator door 6, providing sliding guidance for the slide rail 22, ensuring that the slide rail 22 can only move in the preset direction and avoid deviation.

[0032] For example, the first limiting structure and the second limiting structure refer to the locking structures respectively set at the first limiting position A and the second limiting position B of the slide section 121. With the installation of the limiting post 3 and the spring described later, when the slide section 22 moves to the corresponding position, the limiting post 3 is locked into the hole under the action of the spring preload, thereby locking the position and preventing the slide section 22 from sliding.

[0033] For example, the slide rail 22 refers to the protruding structure on the mounting slider 2 that is adapted to the slide groove 121. The slide rail 22 can be set as a protrusion that matches the cross-sectional shape of the slide groove 121, such as a T-shaped protrusion that is adapted to a T-shaped slide groove. Its surface can be smoothed to reduce sliding resistance. At the same time, a groove or through hole that cooperates with the limiting post 3 is provided at the position of the corresponding limiting structure to improve locking stability.

[0034] This embodiment of the present disclosure provides a sliding groove 121 extending along the length direction on the limiting boss 12 of the base 1, and configures a first and a second limiting structure at two spaced positions of the sliding groove 121. The sliding rail 22 of the mounting slider 2 forms a sliding engagement with the sliding groove 121, so that the sliding rail 22 can be controllably switched between the two limiting positions, thereby driving the second mounting part 21 to adjust its position relative to the first mounting part 11. This not only retains the stable connection function of the traditional hinge, but also gives the assembly position adjustability to adapt to the position requirements under different usage scenarios.

[0035] In this way, the first and second limiting structures precisely position the slide rail 22, ensuring that the slide rail 22 is relatively fixed to the base 1 when it is in the corresponding limiting position, avoiding displacement or loosening caused by vibration or external force, and achieving a dual guarantee of convenient adjustment and positional stability. When this hinge structure 001 is applied to a refrigerator, when the slide rail 22 is in the first limiting position A, the door 6 maintains a fixed assembly relationship with the base 1 through the mounting slider 2, ensuring that the door 6 is flush with the side of the cabinet 7, meeting the appearance requirements of the flush-mounted refrigerator with zero protrusion and the usage requirements of preventing cabinet interference. When it is necessary to disassemble or install internal accessories of the refrigerator, the slide rail 22 switches to the second limiting position B, driving the door 6 to move synchronously with the mounting slider 2, so that the inner wall of the door 6 is no longer covered by the inner liner opening of the cabinet 7, exposing sufficient operating space. Accessory disassembly and assembly can be completed efficiently without disassembling the door 6, completely solving the problem of inconvenient accessory maintenance caused by the excessive thickness of the door 6, while not affecting the sealing performance and flush-mounting effect of the refrigerator, significantly improving the user experience and maintenance convenience of the product.

[0036] Specifically, the slide groove 121 is provided with a first limiting structure corresponding to the first limiting position A. In the first application scenario, the slide rail 22 is adapted to the first limiting structure, directly limiting the displacement of the slide rail 22 within the slide groove 121. In the second application scenario, the slide groove 121 is provided with a second limiting structure corresponding to the second limiting position B. When the slide rail 22 slides along the slide groove 121 to the second limiting position B, the slide rail 22 is adapted to the second limiting structure, directly limiting the displacement of the slide rail 22 within the slide groove 121. Combined with the interval between the two limiting structures, the installation position of the mounting slider 2 relative to the base 1 can be changed, that is, breaking through the limitation that the position of the traditional fixed hinge cannot be adjusted.

[0037] The first limiting structure is configured as a first limiting hole 122, and the second limiting structure is configured as a second limiting hole 123, with the first limiting hole 122 and the second limiting hole 123 being separately disposed; the slide rail part 22 has a third limiting hole 221; The hinge structure 001 also includes a limiting post 3, which is installed in the third limiting hole 221. The limiting post 3 is configured to change from a state of being aligned and inserted into the first limiting hole 122 to a state of being aligned and inserted into the second limiting hole 123, so as to lock the mounting slider 2 in the first limiting hole 122 or the second limiting hole 123.

[0038] For example, the first limiting hole 122 refers to the hole-like structure opened at the first limiting position A of the slide groove 121. For example, it can be a circular through hole or a blind hole with a hole diameter that matches the outer diameter of the limiting post 3. It is used for the limiting post 3 to pass through. Through the fit between the hole wall and the limiting post 3, the sliding of the slide rail 22 at this position is restricted, thereby locking the mounting slider 2.

[0039] For example, the second limiting hole 123 refers to the hole-like structure opened at the second limiting position B of the slide groove 121. It has the same structural shape as the first limiting hole 122, and the two are distributed at intervals in the length direction of the slide groove 121. The interval corresponds to the displacement that the mounting slider 2 needs to be adjusted. Its function is the same as that of the first limiting hole 122, which is used to lock the mounting slider 2 at the second limiting position B.

[0040] For example, the separation setting means that the first limiting hole 122 and the second limiting hole 123 are spatially independent and there is no connected or overlapping area. The center of the two holes maintains a preset distance in the length direction of the slide part 121, ensuring that the limiting post 3 will not be affected by the structure of the other hole when it enters one hole, thus ensuring the reliability of single position locking.

[0041] For example, the third limiting hole 221 refers to a hole-like structure opened on the slide rail 22. Its position is adapted to the sliding trajectory of the slide rail 22, and its diameter matches the outer diameter of the limiting post 3. It is used to accommodate and install the limiting post 3, so that the limiting post 3 can move along its own axis, thereby realizing the alignment and insertion with the first or second limiting hole 123.

[0042] For example, the limiting post 3 refers to a columnar structure adapted to the third limiting hole 221. When inserted, it can extend out of the third limiting hole 221 and be inserted into the first limiting hole 122 or the second limiting hole 123. The material can be a rigid material to ensure structural strength. Through the fit and cooperation with the three limiting holes, a stable locking relationship is formed to fix the position of the mounting slider 2.

[0043] In this embodiment, the first limiting hole 122 and the second limiting hole 123 are separately set at two preset limiting positions of the slide groove 121. The limiting post 3 installed in the third limiting hole 221 of the slide rail 22 is used as the locking medium. By switching between the state of "aligned insertion into the first limiting hole 122" and "aligned insertion into the second limiting hole 123", the precise locking and switching of the mounting slider 2 relative to the base 1 in two fixed positions is realized. This not only maintains the stability of the limiting structure, but also gives the installation position adjustability.

[0044] In this way, when the limiting post 3 is inserted into the corresponding limiting hole, a mechanical lock is formed, which can effectively limit the relative displacement between the mounting slider 2 and the base 1, ensure the connection stability of the two limiting positions, and avoid loosening caused by vibration or external force. At the same time, the limiting post 3 can be switched between the two limiting holes, so that the mounting slider 2 can be stably switched to different installation positions, breaking through the limitation of traditional fixed limiting structures that cannot be adjusted. Moreover, the switching process can be achieved simply by moving the limiting post 3 in alignment, which is convenient to operate. Meanwhile, the separately set first limiting hole 122 and second limiting hole 123 can ensure the independence and accuracy of the two locking positions.

[0045] The hinge structure 001 also includes an elastic element 4, which is sleeved on the outer periphery of the limiting post 3 and supports the limiting post 3. The limiting post 3 is configured to be locked between the first limiting hole 122 and the third limiting hole 221 under the upward elastic force of the elastic element 4, or The limiting post 3 is configured to be locked between the second limiting hole 123 and the third limiting hole 221 under the upward elastic force of the elastic member 4.

[0046] For example, the elastic element 4 refers to the elastic structure that is sleeved around the outside of the limiting post 3. For example, it can be a ring-shaped elastic body whose structural shape is adapted to the outer periphery of the limiting post 3 and has the elastic property of restoring its original shape after being deformed by pressure. It is used to provide support force for the limiting post 3 and generate upward elastic force.

[0047] For example, the inner hole of the elastic element 4 cooperates with the outer peripheral surface of the limiting post 3. The elastic element 4 is fitted on the outside of the limiting post 3 along the axial direction of the limiting post 3, so that the force of the elastic element 4 can be evenly transmitted along the axial direction of the limiting post 3, ensuring that the support and elastic force of the limiting post 3 are applied accurately and effectively.

[0048] For example, the elastic element 4 provides axial support to the limiting post 3 through its own structural shape and elastic deformation, restricting the limiting post 3 from moving downward along its own axis, while providing an upward reset force to the limiting post 3, so that the limiting post 3 always has the tendency to move towards the limiting hole.

[0049] For example, under the upward elastic force of the elastic member 4, one end of the limiting post 3 passes through the third limiting hole 221 of the slide rail 22, and the other end passes through the first limiting hole 122 of the base 1. Through the fit between the limiting post 3 and the walls of the two holes and the elastic pre-tightening force, the relative displacement between the mounting slider 2 and the base 1 is restricted, thereby fixing the two at that position. Alternatively, under the upward elastic force of the elastic member 4, one end of the limiting post 3 passes through the third limiting hole 221 of the slide rail 22, and the other end passes through the second limiting hole 123 of the base 1. Through the same fit between the holes and the elastic pre-tightening method as described above, the mounting slider 2 and the base 1 are stably fixed at the second position.

[0050] This embodiment of the present disclosure uses an elastic element 4 sleeved around the periphery of the limiting post 3. The elastic element 4 supports the limiting post 3 and generates an upward elastic force to construct a dual locking mechanism of elastic pre-tightening and hole alignment. This allows the limiting post 3 to be stably switched and locked between two preset hole combinations. It retains the positional adjustability of the mounting slider 2 relative to the base 1, and strengthens the locking reliability through elastic force, avoiding the problem of locking loosening caused by lack of elastic support.

[0051] In this way, the elastic force continuously acts on the limiting post 3, ensuring that the limiting post 3 fits tightly with the corresponding limiting hole, forming a stable mechanical lock. This effectively resists interference from vibration, external forces, etc., and prevents the limiting post 3 from dislodging from the hole, causing the mounting slider 2 to shift. At the same time, when switching positions, only external force needs to be applied to overcome the elastic force to make the limiting post 3 dislodge from the current hole. After sliding, the elastic element 4 automatically pushes the limiting post 3 to align and lock with the new hole. The operation is convenient and the switching process is smooth. This not only solves the limitation of traditional fixed hinges that cannot adjust the position, but also makes up for the defect of unstable locking in a structure without elastic support.

[0052] The limiting post 3 is configured to move downward from the first limiting hole 122 into the slide groove 121, so that the limiting boss 12 and the slide rail 22 lose axial limitation. The slide rail 22 is configured to continue to move relative to the slide groove 121 until the limiting post 3 passes through the second limiting hole 123, so as to lock the mounting slider 2 in the second limiting hole 123 of the limiting boss 12.

[0053] For example, moving downward means that the limiting post 3 moves away from the first limiting hole 122 along its own axis until the limiting post 3 completely disengages from the first limiting hole 122 and enters the groove cavity of the slide section 121. At this time, the limiting post 3 no longer passes through the holes of the first limiting hole 122 and the slide section 22 at the same time, and loses its axial constraint effect on both.

[0054] For example, axial limiting refers to the limiting effect on the relative displacement of the limiting boss 12 and the slide rail 22 along the axial direction of the limiting post 3. When the limiting post 3 enters the first limiting hole 122, the fit between the hole wall and the limiting post 3 can prevent the two from moving relative to each other in this direction. After the limiting post 3 enters the slide groove 121, the limiting effect in this direction disappears.

[0055] For example, after the axial limit is lost, the slide rail 22 can move relative to the limiting boss 12 along the length direction of the slide groove 121. The slide groove 121 provides guidance for the slide rail 22 through its own groove structure, ensuring that the slide rail 22 moves only in a preset direction and avoids deviation.

[0056] For example, when the slide rail 22 moves to a position where the limiting post 3 is aligned with the second limiting hole 123, the limiting post 3 enters the second limiting hole 123 and fits tightly against the hole wall. The radial constraint of the limiting post 3 prevents the slide rail 22 from continuing to move relative to the slide groove 121, thereby fixing the mounting slider 2 relative to the limiting boss 12 at the position corresponding to the second limiting hole 123, thus achieving locking.

[0057] In this embodiment, the position adjustment and locking of the mounting slider 2 and the limiting boss 12 are achieved by the controllable movement of the limiting post 3. That is, the limiting post 3 moves downward from the first limiting hole 122 into the slide groove 121, releasing the axial limitation between the limiting boss 12 and the slide rail 22, so that the slide rail 22 can continue to move relative to the slide groove 121. After moving to the preset position, the limiting post 3 passes through the second limiting hole 123, and finally locks the mounting slider 2 at the second limiting hole 123 of the limiting boss 12, completing the position switching of the mounting slider 2 relative to the limiting boss 12.

[0058] In this way, the continuous action of the limiting post 3 moving down to release the limiting position, the slide rail 22 moving, and the limiting post 3 locking through the hole not only breaks through the limitation of the traditional fixed structure that cannot adjust the position, but also realizes the dynamic position adjustment of the mounting slider 2 relative to the limiting boss 12. After adjustment, the limiting post 3 and the second limiting hole 123 cooperate to form a stable lock, ensuring that the mounting slider 2 does not loosen in the target position. It takes into account both position adjustability and locking reliability, and can meet the needs of flexibly adjusting the position of the connecting parts and ensuring the stability of use.

[0059] Among them, the elastic element 4 is installed between the limiting post 3 and the third limiting hole 221 so that the elastic potential energy generated by the elastic element 4 directly acts on the limiting post 3.

[0060] For example, the assembly space of the elastic element 4 is limited inside the third limiting hole 221 and is located between the outer peripheral surface of the limiting post 3 and the inner wall of the third limiting hole 221. The inner ring of the elastic element 4 is tightly fitted with the outer periphery of the limiting post 3, and the outer ring is fitted with the inner wall of the third limiting hole 221, forming a nested structure of the inner wall of the third limiting hole 221, the elastic element 4, and the outer periphery of the limiting post 3, ensuring that the elastic element 4 deforms and functions only in this area.

[0061] For example, when the elastic element 4 generates elastic potential energy due to compression, stretching or bending, the force that restores its original shape is not transferred through other structures or additional components of the slide rail 22, but is directly applied to the outer peripheral surface of the limiting post 3, so that the limiting post 3 obtains a thrust toward the limiting hole along its own axis, thereby achieving precise and lossless transmission of elastic force.

[0062] This embodiment of the invention precisely assembles the elastic element 4 at a specific position between the limiting post 3 and the third limiting hole 221, so that the elastic potential energy generated by the elastic element 4 due to compression or deformation does not need to be transmitted through other intermediate components, and directly acts on the limiting post 3. This provides precise and lossless elastic support force for the stable locking of the limiting post 3 in the first limiting hole 122 or the second limiting hole 123, as well as for the position switching between the two limiting holes.

[0063] In this way, the elastic potential energy acts directly on the limiting post 3, which avoids the loss of force transmission and ensures that the limiting post 3 can be tightly locked into the corresponding limiting hole, significantly improving the locking stability, effectively resisting interference such as vibration and external force, and preventing the limiting post 3 from dislodging from the hole and causing the mounting slider 2 to shift. At the same time, the directly applied elastic force means that when the limiting post 3 changes position, only an external force needs to be applied to overcome the elastic force to push it to move. The operation is smooth and effortless, solving the problem of unstable locking when there is no elastic support.

[0064] Among them, the outer periphery of the limiting post 3 protrudes from the abutting platform, the third limiting hole 221 has a bearing plane, one end of the elastic member 4 abuts against the abutting platform, and the other end of the elastic member 4 abuts against the bearing plane, so that the elastic force of the elastic member 4 acts upward on the limiting.

[0065] For example, on the outer circumferential surface of the limiting post 3, a structure with a flat contact surface is formed by protruding radially outward. For example, it can be an annular plane surrounding the outer circumference of the limiting post 3 or symmetrically distributed sheet-like planes. Its flat surface is perpendicular to the axis of the limiting post 3, which is used to provide a stable abutment support point for one end of the elastic member 4, ensuring that the elastic force of the elastic member 4 can be transmitted vertically to the limiting post 3.

[0066] For example, the flat fixing plane formed on the inner cavity wall of the third limiting hole 221 can be located on the inner side of the third limiting hole 221 near the bottom of the hole. Its flat surface is also perpendicular to the axis of the limiting post 3 and is opposite to the abutting platform of the limiting post 3. It is used to provide load-bearing support for the other end of the elastic member 4 and to limit the installation posture and deformation direction of the elastic member 4.

[0067] For example, the two end faces of the elastic element 4 are tightly fitted with the flat surface of the abutment platform and the flat surface of the bearing plane, respectively. When the elastic element 4 is compressed and deformed, its force to restore its original shape can be directly transmitted through the two mating surfaces. One end acts on the abutment platform to push the limiting post 3, and the other end acts on the bearing plane to obtain reverse support, ensuring that the elastic force is transmitted without loss.

[0068] For example, "upward" here refers to the direction relative to the bearing plane toward the abutting platform, that is, toward the limiting hole. It means that the force generated when the elastic element 4 recovers from deformation is directed along the axis of the limiting post 3 from the bearing plane toward the abutting platform, directly pushing the limiting post 3 to move toward the limiting hole, thereby realizing the directional application of the elastic force.

[0069] In this embodiment, a protruding abutment surface is provided on the outer periphery of the limiting post 3, and a bearing plane is provided in the third limiting hole 221. The two ends of the elastic member 4 abut against the abutment surface and the bearing plane respectively. With this structure of positioning and abutting at both ends, the elastic force of the elastic member 4 is oriented and guided to act upward on the limiting post 3. This provides precise and directional elastic support for the stable locking of the limiting post 3 in the corresponding limiting hole and the position switching between the two limiting holes.

[0070] In this way, the upward directional elastic force can continuously push the limiting post 3 towards the limiting hole, ensuring that the limiting post 3 is tightly locked into the corresponding limiting hole, effectively resisting interference from vibration, external forces, etc., and preventing the limiting post 3 from dislodging from the hole and causing the mounting slider 2 to shift, thus significantly improving the structural locking stability. At the same time, when the limiting post 3 changes position, only external force needs to be applied to overcome this directional elastic force to push it to move, making the operation smooth and effortless, and solving the problem of insecure locking when there is no directional elastic force.

[0071] The slide groove 121 is constructed as a cross-shaped through groove, and the slide groove 121 forms an opening C on the bottom surface of the limiting boss 12; the slide rail 22 is constructed as an I-shaped structure, the upper part of the I-shaped structure is placed in the slide groove 121, and the lower part of the I-shaped structure protrudes from the bottom surface of the limiting boss 12 to form a movable toggle part 222.

[0072] For example, the cross-shaped through groove refers to a through groove with a cross-shaped cross section of the slide section 121. The groove extends along the length of the limiting boss 12 and passes through the limiting boss 12 from top to bottom. Its cross structure can form two fitting sections, which respectively cooperate with the upper area and the middle connecting area of ​​the I-shaped slide rail section 22 to provide precise guidance for the slide rail section 22.

[0073] For example, a cross-shaped through groove forms a through opening on the side plane of the limiting boss 12 away from the first mounting part 11. The size of the opening C is adapted to the size of the connecting area in the middle of the I-shaped slide rail part 22, ensuring that the lower part of the slide rail part 22 can pass through the bottom surface of the limiting boss 12 through the opening C.

[0074] For example, the I-shaped structure refers to the cross-sectional shape of the slide rail 22 being I-shaped, and the whole is divided into an upper region, a middle connecting region and a lower region. The width of the upper region and the lower region is greater than that of the middle connecting region, forming a shape that is wide at the top and bottom and narrow in the middle, which is adapted to the cross-shaped through groove structure to achieve sliding fit.

[0075] For example, the upper region of the I-shaped slide rail 22 is embedded in the upper groove section of the cross-shaped through groove. The size of the upper region is precisely matched with the upper groove section, allowing it to slide smoothly along the length of the groove section. At the same time, the side wall of the upper groove section restricts the lateral displacement of the upper region, preventing sliding deviation.

[0076] For example, the lower region of the I-shaped slide rail 22 extends through the slide groove 121 through the opening C on the bottom surface of the limiting boss 12, and the height of the lower region exceeds the bottom surface of the limiting boss 12, so that the region is completely exposed to the outside of the limiting boss 12, forming an operating part that can be directly contacted.

[0077] For example, the toggle part 222 refers to the lower part of the I-shaped slide rail part 22 that protrudes from the bottom surface of the limiting boss 12. This part has a certain width and thickness to form a sufficient operating area. The user can directly push this part with his hand or a simple tool to drive the entire slide rail part 22 to slide along the slide groove part 121. The adjustment operation can be completed without going deep into the structure.

[0078] In this embodiment, the slide groove 121 is configured as a cross-shaped through groove and an opening C is formed on the bottom surface of the limiting boss 12. At the same time, the slide rail 22 is constructed as an I-shaped structure, with the upper region of the I-shaped structure embedded in the slide groove 121 to ensure sliding guidance and fit stability, and the lower region protruding from the bottom surface of the limiting boss 12 to form a toggle part 222. With this structural layout, the sliding direction of the slide rail 22 is restricted by the adaptation of the cross-shaped through groove and the I-shaped structure, and the exposed toggle part 222 provides a direct operating part for the movement of the slide rail 22, so as to realize the controllable adjustment of the mounting slider 2 relative to the base 1.

[0079] In this way, the displacement of the slide rail 22 can be restricted from the vertical direction, preventing deviation or detachment during sliding and ensuring the positional accuracy and structural stability of the slider 2 during adjustment. At the same time, the user can easily drive the slide rail 22 to slide along the slide groove 121 by pushing the toggle part 222, simplifying the adjustment process. Meanwhile, the opening C of the slide groove 121 provides sufficient space for the installation and sliding of the slide rail 22, avoiding structural interference.

[0080] The second mounting part 21 is configured as a first plane, and the first mounting part 11 is configured as a first elevation. The first plane is set perpendicular to the first elevation.

[0081] For example, the second mounting part 21 is constructed as a flat surface on the first plane mounting slider 2 for connecting the parts to be assembled. For example, the plane can be set as a rectangular smooth flat area, and a number of through mounting holes can be opened on the surface to ensure that the parts to be assembled can be tightly attached and fixed on the plane by fasteners, and the connecting surface of the assembled parts completely coincides with the first plane to avoid loosening caused by gaps.

[0082] For example, the first mounting part 11 is constructed as a first vertical surface, which is a flat, upright surface on the base 1 for connecting another component to be assembled. For example, the vertical surface can be set as a rectangular smooth flat area extending vertically on the base 1. Mounting holes can also be opened on the surface for fasteners to pass through to stably fix the base 1 to the component to be assembled, and the extension direction of the vertical surface is perpendicular to the extension direction of the first plane.

[0083] For example, the first plane being perpendicular to the first elevation means that the angle between the first plane and the first elevation is 90 degrees. For example, if the first elevation is a vertically extending elevation along the side wall of the refrigerator body 7, it can be adapted to the vertical installation of the body 7. Then the first plane is a plane extending in the horizontal direction, which can be adapted to the horizontal connection of the door body 6. The perpendicularity of the two ensures that after the door body 6 and the body 7 are assembled, a vertical structure of vertical side wall and horizontal door body 6 is formed, which meets the movement trajectory requirements of the door body 6 opening and closing around the hinge axis 5.

[0084] In this way, by constructing the second mounting part 21 as the first plane and the first mounting part 11 as the first elevation, and setting them perpendicularly, the installation orientation requirements of the two components connected by the hinge are adapted to ensure that the two components can form a preset spatial vertical relationship after assembly, laying a structural foundation for the hinge to achieve stable connection and subsequent functions, while also meeting the orientation positioning requirements during component assembly.

[0085] The hinge structure 001 also includes two hinge shafts 5, and the second mounting part 21 has two separately arranged shaft holes 211, with one hinge shaft 5 correspondingly mounted in one shaft hole 211.

[0086] For example, the two hinge shafts 5 refer to two shaft-like components. For example, they can be cylindrical metal shafts with smoothed outer circumferential surfaces to reduce rotational friction. Their length is adapted to the thickness of the second mounting portion 21 to provide a rotation fulcrum for the connecting components, enabling the connecting components to open and close around the shaft.

[0087] For example, two independent hole-like structures are opened on the second mounting part 21. The two holes are set separately, meaning that the central axes of the two holes are parallel and there is a preset distance. The distance is determined according to the rotation requirements of the connecting parts. The inner diameter of the hole is precisely matched with the outer diameter of the hinge shaft 5 to ensure that there is no obvious gap after the hinge shaft 5 is installed, thus avoiding shaking.

[0088] For example, each hinge shaft 5 is assembled in only one shaft hole 211, and the two are in a one-to-one correspondence. During assembly, the hinge shaft 5 can be fixed in the shaft hole 211 by means of interference fit, riveting or snap-fit, so that the hinge shaft 5 and the second mounting part 21 form a solid connection, ensuring that the two shafts can provide stable support synchronously when the connecting parts rotate.

[0089] In this way, by setting two separate shaft holes 211 in the second mounting part 21, and configuring a hinge shaft 5 for each shaft hole 211, a dual-axis support structure is constructed to adapt to the rotation requirements of the hinge connection components, ensuring that the connection components can open and close stably around the dual axes. At the same time, the separate setting of the shaft holes 211 enables independent positioning and installation of the dual axes. It should be noted that the dual-axis support can significantly improve the stability of the connection components when opening and closing compared with the single-axis support, disperse the pressure of the weight of the door 6 on a single axis, avoid deformation or loosening of the axis after long-term use, and extend the service life of the hinge. The separate setting of the two shaft holes 211 allows each hinge shaft 5 to be installed and maintained independently, reducing assembly errors. At the same time, the dual-axis structure can adapt to the zero-protrusion translation or small-radius rotation requirements of the door 6 in the flat-installation scenario, ensuring that the door 6 does not interfere with the cabinet when opening and closing, taking into account both support stability and flat-installation usage requirements.

[0090] In practical applications, even if some products use dual-axis hinges to enable the door 6 to slide open, the wheelbase remains fixed. When the door 6 is closed, it will still block the liner opening, failing to fundamentally solve the problem of accessory maintainability. Existing flush-mount refrigerator hinges cannot balance the "zero protrusion" flush-mount performance with the ease of maintenance of internal accessories, resulting in low operating efficiency and high costs during production, maintenance and use.

[0091] Based on this, the present disclosure also provides a refrigerator, which includes a cabinet 7 and a door 6. The door 6 is located in the liner area of ​​the cabinet 7. The refrigerator also includes the aforementioned hinge structure 001. A first mounting part 11 is connected to one side of the cabinet 7, and a second mounting part 21 is connected to one side of the door 6. The door 6 is configured to move relative to the cabinet 7 following the movement of the slide rail part 22, so that the door 6 avoids covering the liner area of ​​the cabinet 7.

[0092] For example, the inner opening area of ​​the cabinet 7 refers to the edge area inside the cabinet 7 used for installing or placing detachable accessories, such as glass shelves or sleeve frames, and forming a sealing fit with the door seal of the door 6. For example, it can be the annular edge area at the inner opening C of the cabinet 7. When the door 6 is closed, the door seal needs to be pressed against this area to ensure heat preservation and sealing. This area is also a key operating area that needs to be exposed when the accessories are disassembled and assembled.

[0093] For example, the first mounting part 11 on the hinge base 1 is connected to the side of the housing 7 by fasteners. For example, screws can be passed through the fixing holes of the first mounting part 11 and screwed into the preset threaded holes of the side of the housing 7, so that the hinge base 1 is stably fixed to one side of the housing 7, providing fixed support for the hinge.

[0094] For example, the second mounting part 21 on the hinge mounting slider 2 is connected to the door hinge seat on one side of the door body 6 via the hinge shaft 5. For example, a bushing adapted to the hinge shaft 5 is preset on one side of the door body 6. The hinge shaft 5 is embedded in the bushing so that the door body 6 and the mounting slider 2 are linked together, ensuring that the door body 6 can follow synchronously when the mounting slider 2 moves.

[0095] For example, when the slide rail 22 slides along the slide groove 121, the second mounting part 21, which is integral with the slide rail 22, drives the door 6 to move synchronously. For example, when the slide rail 22 slides away from the housing 7, the second mounting part 21 drives the door 6 to move outward from the housing 7, so that the inner wall of the door 6 is misaligned with the opening area of ​​the housing 7, thus preventing the door 6 from covering the opening. When the slide rail 22 is reset, the door 6 also moves towards the housing 7, returning to the closed state flush with the housing 7.

[0096] This embodiment applies the aforementioned hinge structure 001 with adjustable position function to a refrigerator. By connecting the first mounting part 11 of the hinge to one side of the cabinet 7 and the second mounting part 21 to one side of the door 6, the movable characteristics of the hinge slide rail 22 are used to move the door 6 relative to the cabinet 7. This allows the door 6, which might otherwise cover the liner opening area of ​​the cabinet 7 due to its excessive thickness, to avoid that area. This ensures the refrigerator's flush-mounted appearance while solving the problem of the liner opening being obstructed.

[0097] In this way, the door 6 can move along the slide rail 22 to avoid the liner opening area, exposing the complete liner opening. This provides ample operating space for installing accessories such as glass shelves during production and assembly, and for disassembling accessories during after-sales maintenance or user cleaning. It completely solves the problem of difficult accessory disassembly and assembly caused by the liner opening being blocked in traditional flat-mounted refrigerators. At the same time, after adjustment, the door 6 can be reset through the limiting structure of the hinge, ensuring that the door 6 is flush with the side of the cabinet 7 when closed. This does not damage the zero-protrusion flat-mounted appearance of the refrigerator, and also ensures the sealing fit between the door seal and the cabinet 7, taking into account both ease of use and flat-mounted performance.

[0098] Specifically, when the hinge structure 001 is applied to a refrigerator, when the slide rail 22 is in the first limit position A, if the base 1 is connected to the refrigerator body 7 through the first mounting part 11 and the mounting slider 2 is connected to the refrigerator door 6 through the second mounting part 21, the relative position of the door 6 and the body 7 is fixed, ensuring that the door 6 is flush with the side of the body 7 when closed, meeting the requirements of zero protrusion of the flush-mounted refrigerator and preventing cabinet interference, while ensuring the sealing fit between the door seal and the inner liner of the body 7; when it is necessary to disassemble or install accessories such as internal glass shelves and sleeve frames, the slide rail 22 is moved to the second limit position B, and the mounting slider 2 drives the door 6 to move backward as a whole, so that the inner wall of the door 6 is no longer covered by the inner liner opening of the body 7, exposing the complete liner opening area, providing sufficient operating space for accessory disassembly and assembly, and the operation can be completed without disassembling the door 6, effectively solving the problem of the door 6 being too thick and obscuring the liner opening and the difficulty of accessory disassembly and assembly. At the same time, after adjustment, it can be reset to the first limit position A, without affecting the flush-mounted performance and normal use of the refrigerator.
