Description

Technical Field

[0001] This application belongs to the technical field of hinges, and particularly relates to a modular ultra-thin furniture hinge chassis system and a hinge. Background Art

[0002] A hinge can be used to connect two objects and allow them to rotate relative to each other, and can be widely applied in fields such as construction, machinery, and furniture. For example, as a connecting piece between a door body and a cabinet body, both ends of the hinge are respectively fixed to the door body and the cabinet body, and the hinge arms can rotate relative to the two ends connecting the door body and the cabinet body to open and close the door body.

[0003] When installing a door body through a hinge, since the overall thickness of the existing hinge is relatively large, and the distance between the hinge arms and the side plate of the cabinet body is also relatively large, this will cause a relatively large overhanging force on the connecting part between the hinge arms and the door body during the rotation of the door body. In the case of long-term use, it is easy to cause the connection between the hinge arms and the door body and the cabinet body to become loose or even fall off, thereby shortening the service life of the hinge.

[0004] It should be noted that the above content is not necessarily prior art and does not limit the patent protection scope of this application. Summary of the Invention

It should be understood that although the terms first, second, third, etc. may be used to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or part from another element, component, region, layer, or part. Thus, without departing from the teachings of the present application, the first element, component, region, layer, or part discussed below may be referred to as the second element, component, region, layer, or part. And when discussing the second element, component, region, layer, or part, it does not mean that there must be a first element, component, region, layer, or part in the present application.

[0045] It should be noted that the terms "first", "second", etc. in the specification, claims, and the above-mentioned drawings of the present application are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

Unless otherwise specified, when the numerical interval only refers to the integers within the numerical interval, it includes the two endpoint integers of the numerical range, as well as each integer between the two endpoints, which is equivalent to directly listing each integer. When multiple numerical ranges are provided to describe features or characteristics, these numerical ranges can be combined. In other words, unless otherwise specified, the numerical ranges disclosed in this application should be understood to include any and all sub-ranges subsumed therein. The "numerical values" in the numerical interval can be any quantitative values, such as numbers, percentages, ratios, etc. The "numerical interval" allows for a broad inclusion of quantitative intervals such as percentage intervals, ratio intervals, ratio value intervals, etc.

[0047] An embodiment of the present application provides a modular ultra-thin furniture hinge chassis system and a hinge. Based on this, it is to alleviate the problem that the connection between the hinge arm and the door body and the cabinet body is prone to looseness and detachment during long-term use, thereby shortening the service life of the hinge. See the following text for details.

[0048] Next, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments described herein.

[0049] Please refer to Figures 1 to 4 , an embodiment of the present application provides a modular ultra-thin furniture hinge chassis system, and the modular ultra-thin furniture hinge chassis system includes a first chassis 10, a second chassis 20, a connecting bar 30, and an adjusting column 40. The following is a detailed description:

[0050] The first chassis 10 is a rectangular thin plate structure. The first chassis 10 has opposite first and second side surfaces, and the first chassis 10 serves as the basic part of the entire hinge system.

[0051] Two support plates 108 are respectively vertically provided at the two side edges of the first chassis 10. The parallel arrangement of the support plates 108 and the limiting plate 103 increases the torsional resistance of the first chassis 10 and can effectively prevent the first chassis 10 from undergoing irregular torsion or deformation during use. When the first chassis 10 is subjected to lateral or longitudinal external forces, the support plates 108 can absorb and disperse these external forces.

[0052] The second chassis 20 is a rectangular thin plate structure, which is laminated on the first side surface and clamped on the first chassis 10. The second chassis 20 can provide additional support and stability for the first chassis 10.

[0053] The connecting strip 30 is a long thin sheet structure, which is stacked on the second side surface. The connecting strip 30 is also used for rotationally connecting with the hinge arm.

[0054] Two limiting plates 103 are vertically arranged on the first chassis 10 and extend along the second direction. The two limiting plates 103 are spaced apart to enclose a guide groove, and the guide groove is used to accommodate the connecting strip 30 .

[0055] The guide groove provides a guide for the connecting bar 30, ensuring that the movement of the connecting bar 30 in the second direction will not deviate. That is, the guide groove limits the movement of the connecting bar 30 relative to the first chassis 10 in the first direction, ensuring that the connecting bar 30 can only move along the second direction, thereby avoiding unnecessary deviation or shaking during adjustment or operation.

[0056] During the adjustment process, the limit plate 103 can ensure that the movement trajectory of the connecting strip 30 is always along the direction of the guide groove. The operator can obtain higher controllability when fine-tuning the connecting strip 30, ensuring that the connecting strip 30 will not have errors or deviations when moving along the second direction, thereby improving the accuracy of the adjustment. The guide groove can also be used to accommodate the hinge arm, so that the hinge arm can be partially accommodated in the guide groove to improve the space utilization of the modular ultra-thin furniture hinge chassis system and reduce the space occupied by the hinge. The limit plates 103 can also be other numbers, and the limit plates 103 cooperate with each other to form a guide groove to provide more accurate positioning of the connecting strip 30.

[0057] An adjusting column 40, one end of which is screwed to the hinge arm, and the other end of which is riveted to the connecting bar 30. The adjusting column 40 can rotate axially so that the connecting bar 30 and the hinge arm can rotate relative to each other, so that the hinge arm can be raised or lowered, thereby adjusting the angle between the hinge arm and the connecting bar 30. Specifically, the adjusting column 40 rotates on the hinge arm to move along the axis of the adjusting column 40, thereby driving the connecting bar 30 to move, so as to shorten the distance between the connecting bar 30 and the hinge arm, or to extend the distance between the connecting bar 30 and the hinge arm, thereby adjusting the angle between the hinge arm and the connecting bar 30.

[0058] In this embodiment, the horizontal position of the adjustment column 40 in the third direction is not higher than the horizontal position of the support plate 108 in the third direction, so as to ensure the compactness of the entire hinge chassis system and reduce the overall thickness of the hinge chassis system, making it more suitable for application scenarios with limited space, such as ultra-thin doors or compact equipment.

[0059] Moreover, the horizontal position of the adjusting column 40 is not higher than that of the support plate 108, so that the adjusting column 40 is protected inside the support plate 108. This avoids the exposure of the adjusting column 40 to the outside, reduces the situation of being impacted by external forces or worn, and also avoids the situation where the height of the adjusting column 40 protruding from the support plate 108 causes interference or limitation by other structures.

[0060] One end of the hinge arm is rotatably connected to the connecting bar 30. Among them, the first chassis 10 and the second chassis 20 can be connected to the cabinet body to serve as a weight support structure through the connection with the cabinet body. The other end of the hinge arm can be rotatably connected to the hinge cup, and the hinge cup can be connected to the door body, so that the door body is rotatably connected to the cabinet body.

[0061] In this embodiment, by rotating the adjusting column 40, the hinge arm is lifted or lowered relative to the connecting bar 30 to adjust the connecting end surface between the hinge arm and the door body and the connecting end surface between the hinge arm and the cabinet body. Since the overall structure of this application is relatively thin and the distance base between the hinge arm and the side plate of the cabinet body is relatively small, the overhanging force received by the connecting part between the hinge arm and the door body is relatively small, alleviating the problem that the connection between the hinge arm and the door body is prone to looseness and detachment during long-term use, extending the service life of the hinge. Moreover, the modular ultra-thin furniture hinge chassis system of this application is a flat box structure as a whole, which can greatly reduce the space occupied by the hinge chassis system after installation, so that the hinge can be embedded into the door body or the frame to achieve concealed installation, improving the overall aesthetics of the hinge chassis system, and also protecting the hinge chassis system from external damage or pollution and extending its service life.

[0062] In an optional embodiment, the second chassis 20 includes an opposite first end and a second end. A first buckle 201 is provided at the first end of the second chassis 20, and the first buckle 201 is snap-connected to the first end of the first chassis 10. A second buckle 202 is provided at the second end of the second chassis 20, and the second buckle 202 is snap-connected to the second end of the first chassis 10.

[0063] The first buckle 201 and the second buckle 202 are respectively distributed at the first end and the second end of the second chassis 20. The snap connections between the two ends of the second chassis 20 and the two ends of the first chassis 10 can disperse the stress on the first chassis 10 and avoid local deformation or damage caused by single-point stress on the first chassis 10.

[0064] Specifically, the buckle can be an L-shaped buckle. The L-shaped buckle and the second chassis 20 cooperate to form a card slot to embed the end of the first chassis 10 into the card slot to complete the snap connection.

[0065] Specifically, when installing the first chassis 10 and the second chassis 20, the buckle at one end of the second chassis 20 can be first engaged with one end of the second chassis 20, and then the second chassis 20 can be slightly bent to turn outwards the buckle at the other end of the second chassis 20. After aligning with the other end of the first chassis 10, it can be snapped in.

[0066] The first buckle 201 and the second buckle 202 can restrict the first chassis 10 and the second chassis 20 from moving away from each other, but leave a space for the first chassis 10 and the second chassis 20 to move in the horizontal plane, thus leaving a subsequent fine-tuning space.

[0067] Further, in this embodiment, the modular ultra-thin furniture hinge chassis system further includes a first eccentric bolt 50. The first eccentric bolt 50 passes through the connecting bar 30 and the first chassis 10 and is screwed to the second chassis 20. The first eccentric bolt 50 can rotate axially, and the rotation of the first eccentric bolt 50 can drive the first chassis 10 and the second chassis 20 to move relative to each other in the first direction.

[0068] It should be noted that an eccentric bolt is a special bolt with an eccentric structure. The axis of its threaded shaft does not coincide with the geometric center of the nut, but has a certain offset relative to the geometric center of the nut. When the eccentric bolt rotates, the threaded shaft is limited to rotate in the threaded hole, and the nut rotates with an offset along with the threaded shaft, thereby pushing the structure abutted against the nut to move, so as to achieve the displacement and adjustment functions.

[0069] The following takes the installation of a door body as an example for illustration. In actual installation, the alignment between the door body and the cabinet body is often not perfect, and there may be small misalignments or imbalances. By adjusting the relative movement of the first chassis 10 and the second chassis 20 in the first direction through the first eccentric bolt 50, the door body can move relative to the cabinet body in the first direction, thereby compensating for the errors generated during installation, making the door body and the cabinet body reach the best alignment state, and ensuring the smoothness and sealing performance of opening and closing.

[0070] In this embodiment, the rotation of the first eccentric bolt 50 makes the relative position of the two chassis adjustable. Without the need for additional disassembly or reinstallation, the relative position of the two chassis can be adjusted simply by rotating the first eccentric bolt 50, reducing the maintenance and debugging time and improving the operation convenience.

[0071] Further, in this embodiment, a first positioning hole 301 is opened at the first end of the connecting bar 30, and a strip-shaped hole 101 extending in the second direction is opened at the first end of the first chassis 10; the modular ultra-thin furniture hinge chassis system further includes a first fixing member. The first fixing member passes through the first positioning hole 301 and the strip-shaped hole 101 and is riveted to the end of the strip-shaped hole 101 away from the connecting bar 30.

[0072] In this embodiment, the first fixing member passes through the first positioning hole 301 of the connecting bar 30 and the strip-shaped hole 101 of the chassis to connect the connecting bar 30 and the first chassis 10. The connecting bar 30 can be finely adjusted along the length direction of the strip-shaped hole 101 (i.e., the second direction) to ensure that the connecting bar 30 can be appropriately adjusted as needed during the assembly process. As a structure connected to the hinge arm, adjusting the positions of the connecting bar 30 and the first chassis 10 in the second direction is equivalent to adjusting the position of the hinge arm and the modular ultra-thin furniture hinge chassis system in the second direction, so as to facilitate adjusting the gap size between the door body and the cabinet body when installing the door body to achieve the best alignment effect.

[0073] In this embodiment, the modular ultra-thin furniture hinge chassis system further includes a second eccentric bolt 60. The second eccentric bolt 60 passes through the connecting bar 30 and is fixed to the first chassis 10. The second eccentric bolt 60 can rotate axially, and the rotation of the second eccentric bolt 60 can drive the connecting bar 30 to move relative to the first chassis 10 in the second direction.

[0074] The second eccentric bolt 60 can drive the connecting bar 30 to perform precise fine adjustment relative to the first chassis 10 in the second direction. Taking the installation of the door body as an example, during the installation of the door body, if the alignment between the position of the connecting bar 30 and the first chassis 10 is slightly deviated, using the second eccentric bolt 60 can easily achieve fine adjustment of the position, thereby adjusting the relative position between the hinge arm and the first chassis 10 in the second direction, and further adjusting the gap size between the door body and the cabinet body to improve the flatness of the door body appearance.

[0075] In this embodiment, the adjusting column 40, the first eccentric bolt 50, and the second eccentric bolt 60 are sequentially distributed on the same straight line along the second direction, making the adjustment of the modular ultra-thin furniture hinge chassis system by the operator more simplified and intuitive. The operator can operate these mechanisms sequentially along the second direction to adjust the positional relationship between different components, reducing the complexity of the adjustment and avoiding interference problems that may occur during multi-directional and multi-point adjustments.

[0076] Among them, the first eccentric bolt 50, the second eccentric bolt 60, and the adjusting column 40 can be respectively used to adjust the relative displacements of the modular ultra-thin furniture hinge chassis system in three directions in a three-dimensional space, that is, to adjust the angle between the connecting bar 30 and the hinge arm, to adjust the relative positions of the first chassis 10 and the second chassis 20 in the first direction, and to adjust the relative positions of the connecting bar 30 and the first chassis 10 in the second direction, so as to realize the adjustment of the modular ultra-thin furniture hinge chassis system in a three-dimensional space, so that after installation, problems such as uneven end faces and obvious gaps can be avoided as much as possible, the appearance aesthetics can be improved, and the service life of the modular ultra-thin furniture hinge chassis system can be extended.

[0077] In an alternative embodiment, the modular ultra-thin furniture hinge chassis system further includes two connecting plates 303. The two connecting plates 303 are vertically arranged on opposite side edges of the connecting bar 30 and extend along the second direction. Each connecting plate 303 is provided with a second positioning hole 305. The modular ultra-thin furniture hinge chassis system further includes a rotating shaft 307. The rotating shaft 307 straddles between the second positioning holes 305 of the two connecting plates 303. Both ends of the rotating shaft 307 protrude from the second positioning holes 305. Among them, the protruding parts of the rotating shaft 307 are used for rotatably connecting with the hinge arm, so that the hinge arm can rotate around the axis of the rotating shaft 307, thereby adjusting the angle between the hinge arm and the connecting bar 30 through the adjusting column 40.

[0078] Furthermore, in this embodiment, the limiting plate 103 is formed by stamping, cutting, and bending a partial area on the first chassis 10, and a first through hole 105 is formed in the area after stamping and cutting. By directly forming the limiting plate 103 on the first chassis 10 through stamping, cutting, and bending, the steps of additional processing or welding are omitted. This one-piece forming method simplifies the production process, thereby reducing the production time and cost.

[0079] Moreover, since the limiting plate 103 is directly formed from a part of the first chassis 10 after stamping, cutting, and bending, the limiting plate 103 and the first chassis 10 maintain an integral structure without additional connection points. This integral structure enhances the strength and stability between the limiting plate 103 and the first chassis 10, and reduces the risk of failure caused by loosening or damage of the connecting parts.

[0080] Exemplarily, an "I"-shaped gap can be cut on the first chassis 10, and then this area is stamped to one side, so that the two limiting plates 103 are separated from each other and bent toward one side of the first chassis 10, and finally the limiting plates 103 are formed perpendicular to the first chassis 10.

[0081] In this embodiment, the space reserved by the first through-hole 105 can be used to accommodate the riveting end of the first eccentric bolt 50, the riveting end of the second eccentric bolt 60, or the screw end of the adjusting column 40.

[0082] In other embodiments, the limiting plate 103 can also be fixed to the first chassis 10 by other means, such as being fixed by bolts, welded, etc.

[0083] In an alternative embodiment, fixing holes 203 are provided on the second chassis 20 for connecting with other structures (such as a cabinet body). The support plate 108 is arranged parallel to the adjacent limiting plate 103, and a first aisle hole 107 is provided therebetween.

[0084] The first aisle hole 107 is used to provide a passage for the fixing bolt. After passing through the first aisle hole 107, the fixing bolt then passes through the fixing hole 203 on the second chassis 20 to be fixedly connected with other structures. The first aisle hole 107 can also provide an operating space for workpieces. For example, it provides a passage for the tip of a screwdriver. After the tip of the screwdriver passes through the first aisle hole 107, it abuts against the fixing bolt to tighten / loosen the fixing bolt. The support plate 108 can provide support between the first chassis 10 and other structures, so that there is a certain distance between the first chassis 10 and other structures, leaving a suitable space to enable the fixing bolt and the screwdriver to rotate flexibly, providing installation convenience.

[0085] In an alternative embodiment, the height of the limiting plate 103 is lower than the height of the support plate 108. A baffle 109 is provided at each end of the support plate 108 away from the first chassis 10. The baffles 109 on the two support plates 108 extend towards the side close to each other, and a second aisle hole 1091 corresponding to the first aisle hole 107 is provided on each baffle 109.

[0086] The baffle 109 can strengthen the end of the support plate 108, making the support plate 108 more stable when bearing external forces and not easily bending or deforming. The baffle 109 extending inwards can provide a contact surface for the support plate 108, improving the support effect of the support plate 108 and further enhancing the overall rigidity and stability of the hinge chassis system.

[0087] The second aisle hole 1091 and the first aisle hole 107 are correspondingly arranged, enabling the two aisle holes to form a continuous guiding channel, so that the fixing bolt or the tip of the screwdriver passing through this channel can have an accurate movement path, preventing it from deviating from the predetermined direction during movement.

[0088] Since the first eccentric bolt 50, the second eccentric bolt 60 and the adjusting column 40 adjust the relative positions of the various structures in the modular ultra-thin furniture hinge chassis system, in order to avoid blocking or interfering with the fixing holes 203 on the second chassis 20 due to structural movement. Specifically, in this embodiment, the projection of the fixing holes 203 on the second chassis 20 in the third direction never exceeds the projection of the first aisle hole 107 in the third direction. This enables the modular ultra-thin furniture hinge chassis system to adjust the relative positions between any components, and the fixing holes 203 on the second chassis 20 will never be blocked or interfered with by other structures.

[0089] In an alternative embodiment, the modular ultra-thin furniture hinge chassis system further includes a cover plate. The cover plate is disposed on the first chassis 10. The first chassis 10 forms a support for the cover plate through two support plates 108, and the cover plate and the first chassis 10 form an ultra-thin flat rectangular box.

[0090] The cover plate can block the structures of other components in the modular ultra-thin furniture hinge chassis system, thereby presenting a neat and integrated plane for external display, for various surface treatments or personalized designs, such as spraying, printing or attaching decorations. The specific appearance can be adjusted according to different requirements and is applicable to a variety of industrial or consumer products, enhancing market competitiveness.

[0091] Moreover, the flat rectangular box formed by the cover plate and the chassis through the two support plates 108 can effectively improve the structural strength of the entire hinge chassis system. The cover plate provides additional upper support, enabling better dispersion of pressure when subjected to external forces. The cover plate can also effectively protect the structures of other components (such as the first chassis 10 and the second chassis 20) and functional components (such as the first eccentric bolt 50) inside the modular ultra-thin furniture hinge chassis system, preventing interference and erosion of the internal component structures by particles, dust, moisture or other external environments.

[0092] Please refer to Figure 5 , this embodiment of the present application further provides a hinge having a modular ultra-thin furniture hinge chassis system, including a hinge cup 300, a hinge arm 200 and the modular ultra-thin furniture hinge chassis system 100 in any one of the above. Among them, the hinge cup 300 can be used to connect with the door body. One end of the hinge arm 200 is rotatably connected to the hinge cup 300, and the modular ultra-thin furniture hinge chassis system 100 is connected to the other end of the hinge arm 200. The modular ultra-thin furniture hinge chassis system 100 can also be used to be fixedly connected to the cabinet body, so that the door body is hinged to the cabinet body through the hinge having the modular ultra-thin furniture hinge chassis system 100.

[0093] Furthermore, in this embodiment, a damping mechanism is installed in the hinge cup 300, and the damping mechanism is used to provide a damping force when the hinge arm 200 rotates relative to the hinge cup 300.

[0094] The damping mechanism can slow down the relative rotation speed between the hinge arm 200 and the hinge cup 300, reduce the direct impact and friction between mechanical components, lower the wear rate, and thus extend the service life of the hinge.

[0095] It can be understood that the advantages possessed by the modular ultra-thin furniture hinge chassis system 100 in any of the above embodiments are also possessed by the hinge with the modular ultra-thin furniture hinge chassis system 100 in this embodiment, and will not be elaborated here.

[0096] It should be noted that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. The orientation terms "inner, outer" refer to the inside and outside relative to the contour of each component itself. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "on top of other devices or structures" will be positioned as "below other devices or structures" or "beneath other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations should be made for the relative spatial descriptions used here.

[0097] It should also be noted that the "one embodiment", "another embodiment", "embodiment", etc. mentioned in the present application refer to the specific features, structures or characteristics described in connection with that embodiment being included in at least one embodiment described in the general description of the present application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when describing a specific feature, structure or characteristic in connection with any embodiment, it is intended that the implementation of such feature, structure or characteristic in combination with other embodiments also falls within the scope of the present application.

[0098] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0099] It should also be noted that the above are only the preferred embodiments of the present application, and do not limit the patent protection scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present application.
