Description

Technical Field

[0001] This application relates to the field of hinge technology, and more particularly to a flat, ultra-thin hinge. Background Technology

[0002] A hinge is a mechanical device used to connect two solids and allow them to rotate relative to each other. The two ends of the hinge are installed on the door and the cabinet respectively. The hinge arm can rotate relative to the door and the cabinet to open and close the door.

[0003] Chinese patent CN119177808A discloses a modular ultra-thin hinge chassis system and hinge. The hinge chassis system includes a first chassis and a second chassis that are interlocked with each other. The first chassis and the second chassis can move relative to each other, so that the door moves relative to the cabinet in a first direction, thereby compensating for errors generated during installation and achieving the best alignment between the door and the cabinet.

[0004] However, assembling the second chassis onto the first chassis not only requires labor costs, but also increases the overall thickness of the hinge chassis system, making it occupy a larger space inside the cabinet.

[0036] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0037] Please refer to the following: Figure 1 and Figure 2This application provides a flat, ultra-thin hinge, including a hinge cup 1, a base 2, a movable plate 4, and a hinge arm 3. The hinge cup 1 is used to embed into a panel, the base 2 is used to fix and connect to a cabinet, the movable plate 4 is slidably connected to the base 2, one end of the hinge arm 3 is hinged to the hinge cup 1, and the other end is hinged to the movable plate 4. The base 2 includes a pair of protrusions 21, and the movable plate 4 is clamped between the two protrusions 21. Each protrusion 21 includes a pair of parallel cover plates, and a cavity is formed between the two cover plates. The cover plate that abuts against one side of the cabinet is defined as the second cover plate, and the other cover plate is defined as the first cover plate. The direction in which the movable plate 4 slides relative to the base 2 is defined as the first direction, and the direction in which the two protrusions 21 are opposite is defined as the second direction. The second cover plate is provided with an adjustment hole 23, and the size of the adjustment hole 23 in the second direction is larger than the size in the first direction. As can be seen, by using the flat ultra-thin hinge of this application, the installer can manually adjust the position of the base 2 during installation. By setting the adjustment hole 23, the relative position of the door and the flat ultra-thin hinge can be adjusted, thereby adjusting the relative position of the door and the cabinet, compensating for installation errors, and making the door and the cabinet reach the best alignment. The number of components is small, the installation process is simple, the labor cost is reduced, and the overall thickness of the base 2 is reduced, so that it occupies less space in the cabinet.

[0038] Specifically, such as Figure 1 As shown on the coordinate axis, the first direction is the direction indicated by the X arrow, the second direction is the direction indicated by the Y arrow, and the direction indicated by the Z arrow is defined as the third direction. The first, second, and third directions are perpendicular to each other. A through hole 22 is provided on the first cover plate, located in the third direction of the adjusting hole 23. When the first cover plate is projected towards the third direction (i.e., when the first cover plate is projected towards the second cover plate), the projection of the through hole 22 covers the adjusting hole 23. In other words, the circumferential dimension of the through hole 22 is greater than or equal to the circumferential dimension of the adjusting hole 23. Since the dimension of the adjusting hole 23 in the second direction is greater than its dimension in the first direction, the adjusting hole 23 can move relative to the screw in the second direction, meaning the base 2 can move relative to the cabinet in the second direction. If the projection of the through hole 22 and the projection of the adjusting hole 23 are the same and completely coincident, then when the screw is tightened, the head of the screw abuts against the first cover plate, and the stud portion of the screw... The base 2 passes through the first and second cover plates in sequence and is threaded to the cabinet. However, in order to reduce the weight of the base 2 and the vertical tension it exerts on the cabinet after being connected to it, the protrusion 21 in this embodiment creates a cavity between the first and second cover plates. The protrusion 21 with the cavity can also reduce production costs, but the stud portion of the screw may shift within the cavity, and there is too much unsupported space between the screw head and the cabinet, which is not conducive to connection stability. Preferably, the circumferential dimension of the through hole 22 is larger than that of the adjustment hole 23, so that at least the screw head can be inserted, so that the screw head abuts against the second cover plate after installation. The through hole 22 serves to accommodate the screw.

[0039] In an optional embodiment, the adjustment hole 23 is configured as an oblong hole, the size of which in the second direction is greater than the size in the first direction, the size in the first direction being greater than or equal to the diameter of the screw. Ideally, the size of the oblong hole in the first direction is equal to the diameter of the screw. Since the protrusions 21 are arranged in pairs along the second direction, when the size of the oblong hole in the first direction is equal to the diameter of the screw, it can act as an upper limit base 2 in the first direction, so that the base 2 can only move relative to the screw in the second direction. However, considering the applicability of the flat ultra-thin hinge in this embodiment, the size of the oblong hole in the first direction is configured to be slightly larger to accommodate different types of screws.

[0040] In an optional embodiment, the hinge arm 3 of the flat ultra-thin hinge includes a first arm 31 and a second arm 32. One of the first arm 31 and the second arm 32 is hinged to the hinge cup 1, and the other is connected to the movable plate 4. In this embodiment, the arm connected to the hinge cup 1 is defined as the first arm 31, and the arm connected to the movable plate 4 is defined as the second arm 32. The flat ultra-thin hinge of this embodiment also includes an adjusting screw 6, which is sequentially inserted through the second arm 32 and the movable plate 4, and is threadedly connected to both. When the adjusting screw 6 is rotated axially, the engagement position of the threads of the adjusting screw 6 and the second arm 32 changes, which can adjust the relative position of the second arm 32 and the movable plate 4 in a third direction, that is, adjust the angle of the hinge arm 3 relative to the movable plate 4. Preferably, even if the hinge arm 3 and the movable plate 4 are adjusted to the maximum included angle, the second arm 32 and the adjusting screw 6 will not exceed the plane where the first cover plate is located in the third direction, ensuring the aesthetics of the hinge in this embodiment.

[0041] The second support arm 32 includes an integrally formed bending part 321 and a plug-in part 322. The bending part 321 is used to hinge with the first support arm 31 and plays the role of limiting the hinge cup 1 when the door is closed relative to the cabinet, that is, when the hinge cup 1 is retracted relative to the base 2. The plug-in part 322 is hinged with the movable plate 4. Specifically, the movable plate 4 is provided with a pair of positioning side plates 41. The positioning side plates 41 are used to limit the relative position of the second support arm 32 and the movable plate 4 in the second direction. The pin 42 passes through the positioning side plates 41 and the hinge arm 3, so that the hinge arm 3 can rotate relative to the positioning side plates 41.

[0042] In an optional embodiment, the flat ultra-thin hinge further includes an adjusting member 5. The movable plate 4 has a positioning hole 43. The adjusting member 5 passes through the positioning hole 43 and the base 2 sequentially and is riveted to the base 2. It is used to adjust the relative position of the movable plate 4 and the base 2. Preferably, the adjusting member 5 is configured as an eccentric nail. An eccentric nail is a special bolt with an eccentric structure, where the axis of its thread shaft does not coincide with the geometric center of the nut, but is offset relative to the geometric center of the nut. When the eccentric nail rotates, the thread shaft is confined to rotate within the threaded hole, and the nut rotates offset along with the thread shaft, thereby pushing the structure against the nut to move, achieving displacement and adjustment functions. The axially rotating eccentric nail-like adjusting member 5 can adjust the relative position of the movable plate 4 and the base 2 in the first direction, so as to adjust the gap between the door and the cabinet when installing the door, achieving the best alignment effect.

[0043] As an optional implementation, the modular adjustable hinge may include a damping component (not shown in the figure). The damping component is installed in the hinge cup 1 and is used to provide damping force when the hinge arm 3 rotates relative to the hinge cup 1. This prevents the impact force when the hinge arm and the hinge cup close directly from being too large, which would affect the tightness of the connection and thus affect the service life. The damping component can effectively extend the service life.

[0044] Among them, the adjusting screw 6, the adjusting part 5, and the adjusting hole 23 can be used to adjust the relative displacement of the flat ultra-thin hinge in three directions in three-dimensional space, so that after installation, it can avoid problems such as uneven end faces and obvious gaps as much as possible, improve the appearance and extend the service life of the flat ultra-thin hinge.

[0045] In optional embodiments, such as Figure 3 As shown, the hinge arm 3 of the flat ultra-thin hinge also includes a third arm 33. The third arm 33 is located below the first arm 31 and the second arm 32 in a third direction. One end of the third arm 33 is hinged to the hinge cup 1, and the other end is hinged to the bent portion 321 of the second arm 32 to enhance the connection stability between the hinge cup 1 and the second arm 32.

[0046] In summary, the flat ultra-thin hinge provided in this application allows the installer to manually adjust the position of the base 2 during installation. By adjusting the adjustment hole 23, the relative position of the door and the flat ultra-thin hinge can be adjusted, thereby adjusting the relative position of the door and the cabinet, compensating for installation errors, and achieving the best alignment between the door and the cabinet. It has fewer components, a simpler installation process, reduces labor costs, and reduces the overall thickness of the base 2, resulting in a smaller space occupied by it inside the cabinet.
