[0025] This application provides a cup-shaped concealed hinge. Based on this, the damping component of the hinge can obtain relatively stable and sufficient installation space, achieving a more reliable support and guiding effect, reducing the swaying and offset of the damper 52 during hinge movement, and allowing the damping force to act more stably on the opening and closing movement of the hinge. See below for details.

[0026] 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.

[0027] Please see Figures 1 to 6 This application provides a cup-shaped concealed hinge, which includes a first fixing member 10, a second fixing member 20, a transmission assembly 30, and a damping assembly. The following is a detailed description: The first fastener 10 can be a hinge cup for fixed connection with the door body, and the second fastener 20 can be a fixing seat for fixed connection with the cabinet or wall.

[0028] The transmission assembly 30 is rotatably connected to the first fixing member 10 and the second fixing member 20 at both ends. The transmission assembly 30 includes a first transmission arm 31 and a second transmission arm 32. The second transmission arm 32 is located below the first transmission arm 31, and a first push block 322 is provided at the end of the second transmission arm 32.

[0029] The damping assembly includes a damping sleeve 51, a damper 52, and a sliding sleeve 53. The damping sleeve 51 is fixed in the receiving cavity of the second fixing member 20. The damper 52 is installed in the damping sleeve 51, and the elastic telescopic end of the damper 52 extends out of the damping sleeve 51. The sliding sleeve 53 is slidably connected to one end of the damping sleeve 51 and abuts against the end of the damper 52 that extends out of the damping sleeve 51. The sliding sleeve 53 is also provided with a second push block 512.

[0030] When the transmission assembly 30 rotates around the first fixed member 10, the first push block 322 on the second transmission arm 32 rotates synchronously and pushes the second push block 512, thereby pushing the sliding sleeve 53 to move, so as to compress the damper 52 to generate a damping force.

[0031] This application, by placing the damping assembly within the receiving cavity of the second fixing member 20, provides the damping assembly with relatively stable and sufficient installation space, achieving a more reliable support and guiding effect. Furthermore, by installing the damper within the damping sleeve, the swaying and offset of the damper 52 during hinge movement are reduced, allowing the damping force to act more stably on the opening and closing motion of the hinge, thereby improving the continuity and controllability of the damping effect. Simultaneously, this position is far from the compact area inside the hinge cup, thus not occupying hinge cup space, which helps maintain the overall compactness of the hinge structure and improves assembly and versatility.

[0032] Furthermore, in this embodiment, the end of the second transmission arm 32 away from the first fixing member 10 is provided with two opposing extension plates 321. The two extension plates 321 are respectively located on opposite sides of the sliding sleeve 53, and the first push block 322 is provided on the side of the extension plates 321 facing each other.

[0033] By setting up a pair of extension plates 321 and arranging the first push block 322 on their inner sides respectively, a double-sided force-bearing pushing structure can be formed, making the sliding sleeve 53 more stable when under force, and less prone to swaying or jamming, thereby ensuring the uniformity of force and the reliability of damping effect of the damper 52 during the compression process.

[0034] In this embodiment, the transmission assembly 30 includes a first transmission shaft 33, which includes a first shaft body 331 and a second shaft body 332. The first shaft body 331 and the second shaft body 332 are connected by a connecting section and extend toward the same side.

[0035] The first end of the first transmission arm 31 is rotatably connected to the first shaft 331, the first end of the second transmission arm 32 is rotatably connected to the second shaft 332, and the second end of the second transmission arm 32 is rotatably connected to the damping sleeve 51.

[0036] That is, the first drive shaft 33 can be regarded as a U-shaped shaft. When the drive assembly 30 rotates with the door, the second shaft 332 will rotate around the first shaft 331, so that the second drive arm 32 gradually moves away from or closer to the first drive arm 31, and at the same time drives the first push block 322 on the second drive arm 32 to rotate to push the second push block 512.

[0037] In this embodiment, the damping sleeve 51 includes two opposing first sidewalls, and a groove 511 is provided on the outer side of the first sidewall.

[0038] The sliding sleeve 53 includes two opposing second sidewalls, with two first sidewalls located between the two second sidewalls. A slider 531 is provided on the inner side of the second sidewall, and the slider 531 is slidably disposed in the groove 511 and can slide along the groove 511.

[0039] A groove 511 is provided on the outer side of the damping sleeve 51 to provide a stable guide path for the sliding sleeve 53, so that the movement of the sliding component is controlled and will not deviate due to external force disturbance, thus ensuring the linearity and reliability of the damping process. The cooperation between the slider 531 and the groove 511 forms a reliable sliding guide structure, which can keep the sliding sleeve 53 in stable linear motion during the damping compression process, avoiding shaking, jamming and tilting, thereby ensuring that the damper 52 is subjected to more uniform force, the damping effect is smoother, and the overall durability of the device is improved.

[0040] Furthermore, in this embodiment, the first end of the slide groove 511 is connected to the end of the damping sleeve 51. The slide groove 511 is also provided with a blocking part 513. The blocking part 513 is disposed opposite to the second end of the slide groove 511. The slider 531 can slide between the blocking part 513 and the second end of the slide groove 511, thereby limiting the maximum sliding stroke of the slider 531 and the sliding sleeve 53 connected thereto. This prevents the slider 531 from exceeding the range of the slide groove 511 or from coming off, thereby ensuring that the movement of the sliding sleeve 53 is controlled and its position is stable during the compression of the damper 52, making the working stroke of the damper 52 more controllable.

[0041] In this embodiment, the end of the blocking part 513 away from the first fixing member 10 is provided with an inclined surface 515. When the sliding sleeve 53 and the damping sleeve 51 are installed, the slider 531 of the sliding sleeve 53 can be directly guided from the inclined surface 515 into the groove 511 without additional adjustment or disassembly, simplifying the assembly process, improving the ease of installation, and ensuring the reliability of the fit between the slider 531 and the groove 511.

[0042] In an optional embodiment, the damping sleeve 51 has a clearance opening 516 at one end near the first fixing member 10, and the damper 52 extends partially along the clearance opening 516. The clearance opening 516 allows the damper 52 to extend partially, thereby allowing the use of a longer damper 52, increasing the damping stroke and cushioning effect.

[0043] Furthermore, in this embodiment, the second transmission arm 32 is provided with a relief groove 325, which is used to accommodate the portion of the damper 52 extending along the relief opening 516. The relief groove 325 can prevent the extended portion of the damper 52 from interfering with the second transmission arm 32, ensuring smooth rotation of the second transmission arm 32, thereby improving the smoothness of the cup-shaped concealed hinge rotation.

[0044] In an optional embodiment, guide protrusions 517 are fixed on opposite sides of the damping sleeve 51. The guide protrusions 517 abut against the upper end of the sliding sleeve 53. The thickness of the guide protrusions 517 gradually increases from the end near the first fixing member 10 to the end near the second fixing member 20, so that the damping sleeve 51 abuts against the guide protrusions 517 with a certain inclination, thereby better matching the angle of the second fixing member 20.

[0045] In an optional embodiment, the second end of the first transmission arm 31 is rotatably connected to the second fixing member 20 via the second transmission shaft 312. The end of the second transmission arm 32 is also provided with a third push block 323, which is spaced apart from the second push block 512. An elastic member 315 is also sleeved on the second transmission shaft 312. The elastic member 315 has an extension 316, which extends away from the first fixing member 10 and abuts against the third push block 323.

[0046] In practical applications, the second transmission arm 32 drives the third push block 323 to rotate synchronously, and the extension 316 provides thrust to the third push block 323 so that when the second transmission arm 32 rotates to a preset angle, the thrust generated by the elastic element 315 and the extension 316 is converted into a closing force.

[0047] It should be noted that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. The directional terms "inner" and "outer" refer to the inside or outside relative to the outline of the component itself. For example, if a device in the drawings is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0048] It should also be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this application refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this application.

[0049] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0050] It should also be noted that the above are merely preferred embodiments of this application and do not limit the scope of patent protection of this application.
