Abstract
Description
Technical Field
[0001] The present invention relates to the field of household appliances, and in particular, to a hinge assembly and a refrigeration device. Background Art
[0002] During the manufacturing and use of refrigeration devices (especially multi-door refrigerators), the assembly accuracy of the door hinge assembly directly affects the appearance coordination and structural stability of the device. However, factors such as the deformation of the box foam layer, the accumulation of sheet metal processing tolerances, and transportation vibrations often cause unforeseen offsets in the installation base surface of the hinge assembly, which in turn lead to problems such as the overall tilt of the door and uneven door gaps. Such deviations not only damage the facade beauty of the multi-door refrigerator, but also accelerate the mechanical wear of the hinge shaft and the door installation hole due to the non-central load during repeated opening and closing of the door, significantly shortening the service life of the device in the long term.
[0003] At present, there are two major technical bottlenecks in the hinge assembly position adjustment scheme: Firstly, the operation process is cumbersome - maintenance personnel need to first disassemble the entire hinge assembly, manually support the door to the target position and then re-fasten it. This process must maintain the door posture throughout, and it is extremely difficult for a single person to operate and is prone to cause secondary offsets; Secondly, the structural design constraints - in order to pursue the appearance integrity, the box body often cannot be pre-set with redundant installation holes, resulting in the failure of the conventional hinge assembly position compensation mechanism due to the lack of adjustment margin.

[0030] In the embodiments of the present invention, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.
[0032] In the related art of adjusting the position of a hinge, it is necessary to disassemble the hinge assembly, and then re-align the hinge assembly with a new fixing hole and install it to achieve the purpose of adjusting the position of the hinge assembly. During this period, the operator needs to hold the cabinet door cooperating with the hinge assembly, and the adjustment process is time-consuming and laborious. In addition, for some refrigerators, due to appearance or other requirements, it is not allowed to make adjustments to the fixing hole positions of the hinge relative to the refrigerator cabinet.
[0033] To solve the above problems, the present application proposes a hinge assembly 1, as Figures 1 to 5As shown, the hinge assembly 1 is applied to a refrigeration device. The refrigeration device includes a door 2 and a cabinet 3. The door 2 is hinged to the cabinet 3 through the hinge assembly 1 and is adapted to open or close the storage space of the cabinet 3. The hinge assembly 1 includes: a reinforcing plate 11, a fixing plate 12, a housing, a first limiting member 13, and an eccentric member 14. The reinforcing plate 11 is used to be connected to the cabinet 3 and is provided with a first mounting hole 111 and a first adjusting hole 112 extending along the width direction of the cabinet 3; the fixing plate 12 is used to be rotatably connected to the door 2. At a position corresponding to the first mounting hole 111, the fixing plate 12 is provided with a limiting hole 121, and at a position corresponding to the first adjusting hole 112, a second mounting hole 122 is provided; the housing covers one side of the reinforcing plate 11 and the fixing plate 12; the first limiting member 13 is inserted through the first adjusting hole 112 and the second mounting hole 122; the eccentric member 14 extends from the other side of the reinforcing plate 11 through the first mounting hole 111 to the limiting hole 121. During the rotation of the eccentric member 14, the eccentric member 14 drives the fixing plate 12 to move relative to the reinforcing plate 11, and the first limiting member 13 moves in the first adjusting hole 112, so that under the limiting action, the door 2 moves along the width direction of the cabinet 3.
[0034] In this embodiment, the reinforcing plate 11 is connected to the cabinet 3. The first mounting hole 111 is used to mount the eccentric member 14, which plays a role in limiting and guiding the eccentric member 14 to ensure its movement within a predetermined range. The first adjusting hole 112 is an oblong hole extending along the width direction of the cabinet 3, so that the first limiting member 13 can have a certain moving space therein, thereby allowing the fixing plate 12 to move along the width direction of the cabinet 3 during the adjustment process to realize the adjustment of the position of the door 2. The first limiting member 13 can be a bolt or a screw. The second mounting hole 122 is used to cooperate with and fix the first limiting member 13. The first mounting hole 111 is used to set the eccentric member 14 to ensure that the eccentric member 14 can be stably installed and rotated flexibly. On the one hand, the first limiting member 13 connects the reinforcing plate 11 and the fixing plate 12 to a certain extent, and on the other hand, it plays a role of unidirectional degree-of-freedom constraint on the movement of the fixing plate 12 during the adjustment process, ensuring that the fixing plate 12 can only displace along the width direction of the cabinet 3, thereby realizing the effective control of the position of the door 2. The eccentric member 14 is mainly used for adjustment, and the adjustment of the hinge assembly 1 can be realized by controlling the rotation.
[0035] In the initial state, the reinforcing plate 11 is used to be connected to the box body 3, and the fixing plate 12 is rotatably connected to the box door 2. The box door 2 is rotatably arranged on the box body 3 through the reinforcing plate 11, the fixing plate 12, the first stopper 13 and the eccentric member 14, and the storage space of the box body 3 can be opened or closed normally. When it is necessary to adjust the position of the box door 2, the first stopper 13 can be loosened first and the eccentric member 14 can be rotated. Since the first stopper 13 and the eccentric member 14 are located on the back of the cover, the first stopper 13 and the eccentric member 14 can be adjusted without removing any parts. During the rotation process, the eccentric member 14 will produce corresponding movement in the stopper hole 121, thereby directly pushing the fixing plate 12 to move relative to the reinforcing plate 11 along the width direction of the box body 3. At the same time, the first limit member 13 will move accordingly in the first adjustment hole 112. Due to the restraining effect of the first adjustment hole 112, this movement process is controlled within a specified range, thereby ensuring that the door 2 can move along the width direction of the box body 3, and ultimately achieving the purpose of adjusting the position of the door 2 and making it cooperate with the box body 3.
[0036] The hinge assembly provided by the present invention has a reinforcing plate connected to the box body, a fixing plate rotatably connected to the box door, a cover shell provided on one side of the reinforcing plate and the fixing plate, a first limiter penetrating from the first adjustment hole to the second mounting hole on the other side of the reinforcing plate, and at the same time, an eccentric piece extending from the other side of the reinforcing plate through the first mounting hole to the limiter hole, so that when adjustment is required, there is no need to disassemble any parts in the hinge assembly, and the user can directly rotate the eccentric piece on the side away from the cover shell to complete the adjustment, completely avoiding the cumbersome disassembly process in the traditional solution, and the whole process does not require manual support, simplifying the adjustment process of the hinge assembly. The displacement drive is realized by utilizing the matching relationship between the eccentric piece in the first mounting hole and the limiter hole, and no additional fixing holes need to be opened on the box body during the entire adjustment process, overcoming the technical limitation that the number of holes cannot be increased due to the appearance design or the box body strength requirements.
[0037] like Figure 4 and Figure 5 As shown, the eccentric member 14 includes a rotating portion 141 and a tongue portion 142 eccentrically arranged on the rotating portion 141 . The rotating portion 141 is inserted into the first mounting hole 111 from the other side of the reinforcing plate 11 , and the tongue portion 142 extends into the limiting hole 121 .
[0038] In this embodiment, the eccentric member 14 is mainly used for cooperative adjustment. The tongue portion 142 can be offset by 5° relative to the axis of the rotating portion 141. The rotating portion 141 of the eccentric member 14 can rotate in the first mounting hole 111, while the tongue portion 142 of the eccentric member 14 passes through the limiting hole 121 on the reinforcing plate 11. By controlling the rotation of the rotating portion 141, the tongue portion 142 can be made to move relative to the limiting hole 121. Since the tongue portion 142 is eccentrically arranged, it will generate corresponding movement within the limiting hole 121, thereby directly pushing the fixing plate 12 to move relative to the reinforcing plate 11 in the width direction of the box body 3.
[0039] In some embodiments, as Figures 2 to 5 shown, one of the reinforcing plate 11 and the fixing plate 12 is provided with a third mounting hole 113, and the other is provided with a second adjustment hole 123 at a position corresponding to the third mounting hole 113. The second adjustment hole 123 extends in the width direction of the box body 3 and is generally arranged as a waist-shaped hole.
[0040] Specifically, the second limiting member 15 can usually adopt common fasteners such as bolts and screws. Generally, it does not participate in fixing the reinforcing plate 11 and the fixing plate 12. By passing it through the second adjustment hole 123 on the side of the fixing plate 12 close to the housing to the third mounting hole 113, the second limiting member 15 is generally used to cooperate with the first limiting member 13 to perform limiting on both sides of the reinforcing plate 11 and the fixing plate 12, so that when adjusting the hinge assembly 1, the door 2 can strictly move only relative to the width direction of the box body 3.
[0041] The second limiting member 15 can adopt a detachable connection method. On the one hand, when the position of the door 2 needs to be adjusted, only by loosening and removing the second limiting member 15 can the reinforcing plate 11 and the fixing plate 12 be conveniently loosened. The operation is simple and fast, enabling the reinforcing plate 11 and the fixing plate 12 to move relative to each other under the control of the eccentric member 14 without destructive demolition of the components, thereby improving the efficiency of maintenance and replacement. On the other hand, when the position of the door 2 does not need to be adjusted, the second limiting member 15 can be used to fix the reinforcing plate 11 and the fixing plate 12.
[0042] This embodiment utilizes the cooperation of the second adjustment hole 123, the third mounting hole 113 and the second limiting member 15 to provide a flexible and stable connection solution between the reinforcing plate 11 and the fixing plate 12. When adjustment is needed, the components can be conveniently loosened to achieve precise adjustment of the position of the door 2; while when adjustment is not needed, the firmness of the connection can be ensured to a certain extent.
[0043] In some embodiments, as Figures 2 to 5 shown, the first mounting hole 111 is generally also arranged as a waist-shaped hole, extending along the depth and / or width direction of the box body 3 to facilitate controlling the rotation of the rotating portion 141 of the eccentric member 14 in the first mounting hole 111.
[0044] This design enables the eccentric member 14 to adapt to different position requirements during the adjustment process, further enhancing the flexibility and adaptability of the hinge assembly. When the rotating portion 141 of the eccentric member 14 rotates in the first mounting hole 111 of the waist-shaped hole, it can provide sufficient space for the tongue portion 142 to push the fixing plate 12 to move, thereby achieving more precise adjustment of the cabinet door 2. At the same time, this also facilitates the adaptation between cabinet doors of different sizes and specifications and the cabinet body, enabling this hinge assembly to be applicable to a variety of different refrigeration devices, and improving its versatility and practicality.
[0045] In addition, setting the first mounting hole 111 as a waist-shaped hole can also alleviate the component fitting problems caused by manufacturing errors or installation errors to a certain extent. During the actual production process, there may be certain deviations in the dimensions of the components, and the design of the waist-shaped hole can make up for these deviations to a certain extent, enabling the eccentric member 14 to be smoothly installed and operate normally, ensuring the reliability and stability of the hinge assembly.
[0046] In some cases, in order to further optimize the adjustment effect and improve the performance of the hinge assembly, the shape and size of the first mounting hole 111 can also be adjusted. For example, according to the actual adjustment requirements and the size of the eccentric member 14, the length and width of the waist-shaped hole can be appropriately increased or decreased to provide a more suitable rotation space and adjustment range. At the same time, chamfering or rounding can be performed on the edge of the waist-shaped hole to reduce stress concentration, improve the fatigue strength of the components, and extend the service life of the hinge assembly.
[0047] To increase the stability of the relative sliding between the cabinet door 2 and the cabinet body 3, a plurality of third mounting holes 113 are formed on the reinforcing plate 11, a plurality of second adjustment holes 123 corresponding one-to-one to the plurality of third mounting holes 113 are formed on the fixing plate 12, a plurality of second limiting members 15 are provided, and each second limiting member 15 is detachably inserted through the correspondingly arranged third mounting hole 113 and the second adjustment hole 123. Those skilled in the art should understand that the second adjustment holes 123 extend along the width direction of the cabinet body and are generally set as waist-shaped holes to facilitate the movement of the second limiting members 15, so as to limit the fixing plate 12 during the adjustment process.
[0048] Through the restraining action of multiple limiting points, it is ensured that when the fixing plate 12 moves along the width direction of the cabinet body, its movement trajectory is more stable, preventing the cabinet door 2 from tilting or jamming due to uneven single-point force. This multi-point cooperation limiting method greatly improves the stability of the relative sliding between the cabinet door and the cabinet body.
[0049] In practical applications, for example, when the refrigeration equipment is subjected to external impacts or needs to recalibrate the position of the cabinet door after long-term use, the multiple second limit members 15 can evenly disperse the acting force, thereby reducing the risk of deformation or damage of a single limit point due to excessive force and extending the service life of the hinge assembly.
[0050] In some embodiments, the second limit member 15 can also be a screw with a self-locking function. In this way, after being adjusted to the appropriate position, it can automatically lock to prevent the limit member from loosening due to vibrations or other reasons, further ensuring the stability of the cabinet door position. In addition, for easy identification and operation, color marks or scale marks can be set on the head of each second limit member 15. The operator can quickly judge the tightening degree of the limit member according to the color or scale, realizing precise adjustment and improving work efficiency at the same time.
[0051] Similarly, a plurality of first adjustment holes 112 are formed on the reinforcing plate 11. At corresponding positions on the fixing plate 12, a plurality of second mounting holes 122 are provided that are arranged in one-to-one correspondence with the plurality of first adjustment holes 112. A plurality of first limit members 13 are provided, and each first limit member 13 is detachably inserted through the corresponding first adjustment hole 112 and second mounting hole 122.
[0052] The plurality of first adjustment holes 112 are distributed in the width direction of the cabinet 3, providing more adjustment points for the fine adjustment of the cabinet door 2, so that the position of the cabinet door 2 can be adjusted more precisely. At the same time, the plurality of first limit members 13 move respectively in the corresponding first adjustment holes 112, playing a role in evenly distributing and sharing the acting force, avoiding deformation or damage of components caused by excessive force at a single point, and thus ensuring the smoothness and reliability of the adjustment process.
[0053] When the position of the cabinet door 2 needs to be finely adjusted, only need to loosen the corresponding first limit member 13 and rotate the eccentric member 14, so that the fixing plate 12 moves relative to the reinforcing plate 11. At the same time, the plurality of first limit members 13 move correspondingly in their respective first adjustment holes 112. In this way, the moving distance of the cabinet door 2 can be controlled more precisely to achieve precise alignment. Moreover, the multi-point limit design helps to prevent the cabinet door 2 from shifting due to external forces during use, improving the fitting accuracy and sealing performance between the cabinet door 2 and the cabinet 3, and ensuring the normal use and energy-saving effect of the refrigeration equipment.
[0054] Optionally, at least two of the second adjustment holes 123 are arranged at different positions extending in the depth direction of the cabinet 3. In order to use the plurality of second adjustment holes 123 to complete the limitation of the second limit member 15 so that the cabinet door 2 can only move in the width direction of the cabinet 3, the plurality of second adjustment holes 123 need to be arranged in parallel. Therefore, generally all the second adjustment holes 123 need to be arranged at different positions extending in the depth direction of the cabinet 3, and at the same time, the plurality of second adjustment holes 123 cooperate with the second limit member 15 to complete the limitation.
[0055] To complete the fixation of the reinforcement plate 11, as Figures 2 to 5 shown, a fourth mounting hole 114 is formed on the reinforcement plate 11; the hinge assembly 1 further includes: a fixing member; the fixing member passes through the fourth mounting hole 114 and is used to be fixed in the box body 3.
[0056] During specific installation, the fixing member passes through the fourth mounting hole 114 on the reinforcement plate 11, and then firmly fixes the reinforcement plate 11 in the box body 3, so that the reinforcement plate 11 can stably bear the weight of the door 2, and during the frequent opening and closing of the door 2, the stability and reliability of the entire hinge assembly 1 are maintained. By reasonably setting the position and quantity of the fourth mounting holes 114, multi-point fixation of the reinforcement plate 11 can be achieved, thereby further improving the connection strength between it and the box body 3, and ensuring the durability and stability of the hinge assembly 1 during long-term use.
[0057] In some embodiments, as Figures 2 to 5 shown, the hinge assembly 1 further includes: a rotating shaft 16, one end of the rotating shaft 16 is connected to the fixing plate 12, and the other end of the rotating shaft 16 is used for rotatably connecting with the door 2.
[0058] For example, one end of the rotating shaft 16 is connected to the fixing plate 12 by reliable means such as welding, riveting or threaded connection, etc., to ensure that torque can be stably transmitted between the two and the weight of the door 2 can be borne. The other end of the rotating shaft 16 is designed to cooperate with the corresponding structure on the door 2 (such as the rotating shaft 16 mounting hole or rotating shaft 16 seat on the door 2), so as to realize the rotational connection between the door 2 and the fixing plate 12.
[0059] In this embodiment, by providing the rotating shaft 16, the door 2 can rotate flexibly around the rotating shaft 16, so as to realize the opening and closing actions. The rotating shaft 16 not only has sufficient strength and stiffness to bear the weight of the door 2 and transmit the acting forces during opening and closing, but also can ensure the wear resistance and fatigue resistance during long-term use, so as to ensure the service life of the hinge assembly 1.
[0060] To facilitate electrical conduction, as Figures 2 to 5 shown, a grounding hole is formed on the reinforcement plate 11, an avoidance groove 124 is formed at the corresponding position on the fixing plate 12, and the hinge assembly 1 further includes: an electrical conductive member 17, the electrical conductive member 17 passes through the grounding hole and is arranged in the box body 3.
[0061] The conductive member 17 is usually made of a material with good electrical conductivity, such as a copper alloy or a metal member plated with a conductive layer. The conductive member 17 passes through the grounding hole on the reinforcing plate 11 and is further connected to the grounding system of the box body 3. During installation, one end of the conductive member 17 is inserted into the grounding hole, and through a suitable fixing method (such as screw connection, welding or crimping, etc.), its good electrical contact with the box body 3 is ensured, so as to realize the conduction of the electrical circuit.
[0062] When the box door 2 is closed, the contact between the fixing plate 12 and the reinforcing plate 11 may form a certain potential difference. Especially when the box door 2 is frequently opened and closed or there is electromagnetic interference, the cooperation of the grounding hole and the conductive member 17 can effectively guide the static electricity or leakage signals that may be generated to the grounding system of the box body 3, prevent charge accumulation, reduce the risk of electric shock, and ensure the safety of users. At the same time, this grounding design also helps to improve the electromagnetic compatibility of the entire refrigeration equipment and reduce the impact of electromagnetic interference on the internal electronic components of the equipment.
[0063] The present application also proposes a refrigeration equipment. Taking a single-door refrigerator as an example, as Figures 1 to 5 shown, the refrigeration equipment includes: a hinge assembly 1, a box door 2, and a box body 3. The box body 3 is hinged to the box body 3 through the hinge assembly 1 and is adapted to open or close the storage space of the box body 3. The hinge assembly 1 includes: a reinforcing plate 11, a fixing plate 12, a housing, a first limiting member 13, and an eccentric member 14. The reinforcing plate 11 is used for connecting to the box body 3 and is provided with a first mounting hole 111 and a first adjusting hole 112 extending along the width direction of the box body 3; the fixing plate 12 is used for rotatably connecting to the box door 2, and the fixing plate 12 is provided with a limiting hole 121 at a position corresponding to the first mounting hole 111 and a second mounting hole 122 at a position corresponding to the first adjusting hole 112; the housing covers one side of the reinforcing plate 11 and the fixing plate 12; the first limiting member 13 passes through the first adjusting hole 112 and the second mounting hole 122; the eccentric member 14 extends from the other side of the reinforcing plate 11 through the first mounting hole 111 to the limiting hole 121. During the rotation of the eccentric member 14, the eccentric member 14 drives the fixing plate 12 to move relative to the reinforcing plate 11, and the first limiting member 13 moves in the first adjusting hole 112, so that the box door 2 moves along the width direction of the box body 3 under the limiting action.
[0064] In the initial state, the reinforcing plate 11 is used to be connected to the box body 3, and the fixing plate 12 is rotatably connected to the box door 2. The box door 2 is rotatably arranged on the box body 3 through the reinforcing plate 11, the fixing plate 12, the first stopper 13 and the eccentric member 14, and the storage space of the box body 3 can be opened or closed normally. When it is necessary to adjust the position of the box door 2, the first stopper 13 can be loosened first, and the eccentric member 14 can be rotated. During the rotation process, the eccentric member 14 will produce corresponding movement in the stopper hole 121, and then directly push the fixing plate 12 to move along the width direction of the box body 3 relative to the reinforcing plate 11. At the same time, the first stopper 13 will move accordingly in the first adjustment hole 112. Due to the constraint of the first adjustment hole 112, this movement process is controlled within the specified range, thereby ensuring that the box door 2 can move along the width direction of the box body 3, and finally achieving the purpose of adjusting the position of the box door 2 and making it cooperate with the box body 3.
[0065] The refrigeration equipment provided by the present invention has a reinforcing plate connected to the box body, a fixing plate rotatably connected to the box door, a cover shell provided on one side of the reinforcing plate and the fixing plate, a first limiter penetrating from the first adjustment hole to the second mounting hole on the other side of the reinforcing plate, and at the same time, an eccentric member extending from the other side of the reinforcing plate through the first mounting hole to the limiter hole, so that when adjustment is required, there is no need to disassemble any parts in the hinge assembly, and the user can directly rotate the eccentric member on the side away from the cover shell to complete the adjustment, completely avoiding the cumbersome process of disassembly in the traditional solution, and the whole process does not require manual support, simplifying the adjustment process of the hinge assembly. The displacement drive is realized by utilizing the matching relationship between the eccentric member in the first mounting hole and the limiter hole, and no additional fixing holes need to be opened on the box body during the entire adjustment process, overcoming the technical limitation that the number of holes cannot be increased due to the appearance design or the box body strength requirements.
[0066] The refrigeration device can also be a double-door refrigerator, such as Figure 6 As shown, there are two box doors 2, namely the first box door 21 and the second box door 22; there are two hinge assemblies 1, namely the first hinge assembly and the second hinge assembly; the first box door 21 is rotatably connected to the left side of the box body 3 through the first hinge assembly, and the second box door 22 is rotatably connected to the right side of the box body 3 through the second hinge assembly, so as to open or close the storage space through the first box door 21 and the second box door 22.
[0067] In actual use, the user can open one of the doors 2 or both doors 2 at the same time as needed. For example, the first door 21 and the second door 22 can be used to open and close the refrigerator compartment. The refrigerator compartment is provided with two doors 2 to meet different usage requirements. At the same time, the first door 21 and the second door 22 can be controlled independently, which improves the flexibility of use.
[0068] When it is necessary to adjust the positions of the first box door 21 or the second box door 22, it is only necessary to adjust the first hinge assembly and the second hinge assembly, and rotate the rotating part 141 of the corresponding eccentric part 14. During the rotation, since the tongue part 142 is eccentrically arranged, it will generate corresponding movements in the corresponding limit holes 121, and then directly push the corresponding fixing plate 12 to move relative to the reinforcing plate 11 in the width direction of the box body 3. At the same time, the first limiting part 13 will move correspondingly in the corresponding second adjusting hole 123. Due to the restraining effect of the first limiting part 13, this moving process is controlled within a specified range, so as to ensure that the first box door 21 or the second box door 22 can move along the width direction of the box body 3. The first hinge assembly can be used to control the first box door 21 to move along the width direction of the box body 3, and the second hinge assembly can be used to control the second box door 22 to move along the width direction of the box body 3, so that the distance between the first box door 21 and the second box door 22 can be adjusted.
[0069] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
