[0004] The embodiments of the present application provide a pull-type cup head damping hinge to solve or alleviate one or more technical problems in the prior art.

[0005] In a first aspect, an embodiment of the present application provides a pull-type cup head damping hinge, comprising: The hinge cup assembly is used to connect to the door body and specifically includes: A cup body, wherein the surface of the cup body is concave downward to form a first receiving groove, and an opening is formed at a side end of the bottom of the first receiving groove; a transmission member, slidably mounted below the cup body, and capable of sliding relative to the cup body in a predetermined direction; a damping member, mounted on the cup body, wherein the damping rod of the damping member is connected to the transmission member; a rotating shaft, spanning the first receiving groove; a transmission plate, rotatably connected to the rotating shaft, one end of the transmission plate extending out of the opening and abutting against the transmission member; Chassis assembly, used for fixed connection with the cabinet; A hinge arm, with two ends respectively connected to the hinge cup assembly and the chassis assembly; When the door is closed, the transmission plate and the cup rotate along the shaft, so that the transmission plate drives the transmission member to slide in a predetermined direction, causing the transmission member and the cup to move relative to each other, thereby pulling the damping rod to generate a damping force.

[0006] Optionally, the surface of the cup body is recessed downward to form a cup edge and a cup bulge, and a baffle is provided on the side of the cup bulge away from the cup edge. The baffle and the outer wall of the cup body cooperate to form a guide groove for accommodating a transmission member.

[0008] Optionally, the guiding groove includes a first guiding groove and a second guiding groove, and the first guiding groove and the second guiding groove are respectively located on opposite sides of the cup protrusion; The guiding block includes a first guiding block and a second guiding block. The first guiding block is adapted to be slidably mounted in the first guiding groove, and the second guiding block is adapted to be slidably mounted in the second guiding groove.

[0009] Optionally, a convex plate is provided at an end of the transmission plate close to the bottom wall of the first receiving groove, and a stopping portion is provided on the transmission member. The convex plate extends out along the opening and abuts against the stopping portion.

[0024] Hinge structures are widely used in various devices such as doors, windows, and lockers. As a connecting component between the door or window body and the frame, they play a role in support and rotation. During actual use, when the door or window body is closed, it may quickly close due to its own weight or external force, easily generating a large impact force and noise, which may then cause wear, cracking, etc. to the hinge or the door and window.

[0025] Based on the above, the embodiments of this application provide a pull-type cup head damping hinge to slow down the closing speed of the door and relieve problems such as impact force and noise generated during closing. See the following for details.

[0026] Next, exemplary embodiments according to this 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.

[0027] Please refer to Figures 1 to 4 , the embodiments of this application provide a pull-type cup head damping hinge, which includes a hinge cup assembly 100, a chassis assembly, and a hinge arm. The following is a detailed description: The hinge cup assembly 100 is used to connect to the door body and specifically includes a cup body 10, a transmission member 20, a damping member 30, a rotating shaft, and a transmission plate 50. Among them, a first accommodation groove 11 is formed by the surface of the cup body 10 being recessed downward, and an opening 12 is provided at the side end of the bottom of the first accommodation groove 11. The transmission member 20 is slidably installed below the cup body 10, and the transmission member 20 can slide relative to the cup body 10 along a predetermined direction. The damping member 30 is installed on the cup body 10, and the damping rod 31 of the damping member 30 is connected to the transmission member 20. The rotating shaft straddles within the first accommodation groove 11, and the transmission plate 50 is rotatably connected to the rotating shaft. One end of the transmission plate 50 extends out of the opening 12 and abuts against the transmission member 20.

[0028] The chassis assembly is used to be fixedly connected to the cabinet body, and both ends of the hinge arm are respectively connected to the hinge cup assembly 100 and the chassis assembly.

[0029] In actual use, the hinge cup assembly 100 is fixed to the door body. When the door is closed, the hinge as a whole retracts inward, and the transmission plate 50 rotates toward the cup body 10, causing the transmission plate 50 to abut against the transmission member 20 and push the transmission member 20 to move, causing the transmission member 20 and the cup body to generate relative motion. When the transmission member 20 moves, it pulls the damping rod 31 outward to generate a damping force, thereby slowing the door closing speed and reducing the impact force and noise of closing the door. In addition, when the damping rod 31 is pulled, the pressure change in the internal cavity of the damping member 30 is relatively small, and the force is relatively evenly applied, which can extend the service life of the damping member 30.

[0030] Furthermore, in this embodiment, the surface of the cup body 10 is recessed downward to form a cup rim 13 and a cup convex portion. A baffle 141 is provided on the side of the cup convex portion away from the cup rim 13. The baffle 141 cooperates with the outer wall of the cup body 10 to form a guide groove 143, which is used to accommodate the transmission member 20. The guide groove 143 defines a sliding path for the transmission member 20, ensuring that it can slide smoothly in a predetermined direction and avoid deflection or jamming.

[0031] Specifically, guide groove 143 provides multi-faceted spatial positioning for transmission member 20, providing stable guidance and control during its movement, preventing wobbling or deviation from its trajectory due to excessive lateral clearance. Furthermore, the shape and depth of guide groove 143 can be tailored to the size and travel of transmission member 20, achieving a high-precision fit and further enhancing the accuracy and durability of the sliding fit.

[0032] In addition, the baffle 141 not only serves as a limiting structure for the transmission part 20, but also improves the structural strength of the edge of the cup body 10 to a certain extent, preventing deformation or cracking under transmission loading or door vibration, and enhancing the reliability and fatigue resistance of the overall hinge structure.

[0033] Specifically, the guide groove 143 can be naturally formed by the main structure of the cup body 10, such as integral molding or casting, reducing the number of parts and assembly steps, without the need to add additional guide rails or guide structures, which can effectively reduce material costs and mold complexity and facilitate large-scale production.

[0034] In addition, since the guide groove 143 and the cup body 10 are an integrated structure, the accuracy and stability of the guide position can be ensured, avoiding deviations caused by assembly errors or accumulated tolerances between parts, which helps to improve the smoothness of the sliding process of the transmission member 20.

[0035] Further, in an alternative embodiment, a guiding block 21 is provided on the transmission member 20. The guiding block 21 is adapted to be received in the guiding groove 143 and slide along the guiding groove 143. The guiding groove can limit the sliding direction of the guiding block 21, avoiding a decrease in transmission efficiency or structural jamming caused by skewing, thereby ensuring the smoothness and reliability of the sliding block.

[0036] In some embodiments, to enhance the guiding effect, the guiding block 21 can be configured in a sliding column shape or a sliding groove shape to form a relatively stable positioning and mating relationship within the guiding groove 143, effectively suppressing lateral swaying or inclined deformation of the transmission member 20 during the sliding process.

[0037] In practical applications, the clearance fit between the guiding block 21 and the guiding groove 143 can adopt a tight clearance or a clearance fit, enabling it to have a good guiding and positioning function while ensuring sliding flexibility, and enhancing the operating stability of the structure.

[0038] In some embodiments, the inner wall of the guiding groove 143 can also be lubricated or made of a material with a low friction coefficient, such as by setting a coating, embedding a plastic guide rail, etc., to further reduce the sliding resistance and improve the response sensitivity and service life of the overall mechanism.

[0039] In an alternative embodiment, the guiding groove 143 includes a first guiding groove and a second guiding groove. The first guiding groove and the second guiding groove are respectively located on opposite sides of the cup protrusion. The guiding block 21 includes a first guiding block and a second guiding block. The first guiding block is adapted to be slidably mounted in the first guiding groove, and the second guiding block is adapted to be slidably mounted in the second guiding groove.

[0040] Specifically, the first guiding groove and the second guiding groove are distributed on both sides of the cup protrusion, enabling the two guiding blocks 21 to be correspondingly inserted into the guiding grooves 143 on both sides, thereby forming a double-point support sliding structure, avoiding lateral swaying or inclination of the transmission member 20 during the sliding process, and making the sliding action smoother. Moreover, the double-guiding structure can achieve uniform distribution of the load during use, making the transmission member 20 less likely to undergo force-induced deformation and reducing the risk of damage.

[0041] In an alternative embodiment, a convex plate 51 is provided at an end of the transmission plate 50 close to the bottom wall of the first receiving groove 11. A stop portion 23 is provided on the transmission member 20. The convex plate 51 extends out along the opening 12 and abuts against the stop portion 23.

[0042] During actual use, when the hinge acts (such as when the door body is closed) to drive the rotation of the transmission plate 50, the convex plate 51 converts the rotational motion into a thrust force and applies this thrust force to the transmission member 20 by contacting the stop portion 23, thereby driving the transmission member 20 to slide along the direction of the guiding groove 143, causing the transmission member 20 to pull the damping member 30 to generate a damping force.

[0043] In an optional embodiment, a accommodating frame 15 is provided on the cup body 10, and the accommodating frame 15 is used to accommodate the damping member 30. A through opening 151 is provided at one end of the accommodating frame 15, and the damping rod 31 of the damping member 30 extends out of the through opening 151 and is fixedly connected to the transmission member 20.

[0044] In one embodiment, the containing frame 15 has a through opening 151 at only one end to wrap the damping member 30 inside, which can prevent most impurities such as dust, oil, water vapor, etc. from entering, thereby improving the service life of the damping structure. In addition, the containing frame 15 can provide structural limitation and support for the damping member 30 to prevent it from offset, shaking or loosening during operation, and can maintain the accuracy and axial stability of the damping rod 31 during movement, thereby improving the controllability and consistency of the damping effect.

[0045] In some embodiments, the receiving frame 15 can be disposed inside or outside the cup body. That is, the damping member 30 can be housed within the cup body or mounted externally thereto. The mounting location of the damping member 15 on the cup body is not specifically limited; it only needs to be able to be pulled to generate a damping force when the door is closed. In some embodiments, the receiving frame 15 can also be formed by directly deforming the sidewall of the cup body.

[0046] The damping member 30 is hidden in the space below the cup body 10, making full use of the internal space of the hinge structure without adding extra thickness or exposed parts, which can meet the requirements of modern furniture for neat appearance and compact structure.

[0047] Furthermore, the transmission member 20 is provided with a locking groove 25, and an insert 33 is provided at the end of the damping rod 31 extending from the through opening 151. The insert 33 of the damping rod 31 is retained within the locking groove 25. The locking groove 25 provides a structural constraint on the insert 33, preventing the damping rod 31 from loosening or slipping due to vibration or inertia during long-term use, thereby improving the safety and reliability of the damping assembly connection.

[0048] A sliding hole is formed on one side of the slot 25 and communicates with the slot 25. During installation, the insert 33 is aligned with the slot 25, the damping rod 31 is aligned with the sliding hole, and the damping member 30 is moved downward, allowing the damping rod 31 to slide downward along the sliding hole. Simultaneously, the insert 33 engages the slot 25, completing the assembly. This simple and efficient installation process requires no additional tools or fasteners. If the damping member 30 needs to be replaced or repaired, simply remove the insert 33 from the slot 25 to separate it from the transmission member 20, without disassembling the hinge.

[0049] In an optional embodiment, the damping member 30 includes a first damping member and a second damping member, and the containing frame 15 includes a first containing frame and a second containing frame, the first containing frame and the second containing frame are respectively fixed on opposite sides of the cup bulge, the first containing frame is used to accommodate the first damping member, and the second containing frame is used to accommodate the second damping member, and the first damping member and the second damping member are both fixedly connected to the transmission member 20.

[0050] Both damping members 30 are fixedly connected to the same transmission member 20 through their respective damping rods 31. The first damping member and the second damping member can synchronously produce a damping effect on the transmission member 20. The superposition of the damping forces can significantly improve the overall buffering capacity. For some larger or heavier door structures, it can ensure that the buffering during the closing process is sufficient and the movement is softer.

[0051] The two damping elements 30 are symmetrically positioned on either side of the transmission element 20, distributing force symmetrically and balancing the sliding motion of the transmission element 20. This effectively prevents problems such as shaking, deflection, and jamming caused by unilateral force, ensuring smoother sliding and smoother operation. Furthermore, in some cases, if one damper fails, the other can still provide partial damping, providing redundant protection.

[0052] In an optional embodiment, the cup rim 13 is provided with a fixing hole 131, through which a fixing member can pass and be fixedly connected to the door body, thereby connecting the hinge cup assembly 100 to the door body. Specifically, there can be multiple fixing holes 131, and the fixing holes 131 can be set at the end corners of the cup rim 13. During installation, a fixing member such as a screw is passed through the fixing holes 131 to firmly connect the cup body 10 to the inner side of the door body, thereby achieving mechanical fixation between the hinge and the door body.

[0053] In this embodiment, the cup body 10 may be made of iron, and the transmission member 20 may be made of plastic.

[0054] The cup body 10 serves as the structural foundation directly fixed to the door body. The use of iron material can effectively improve the overall load-bearing capacity and anti-deformation performance. It can remain firmly installed during long-term use and is not easy to loosen or bend and deform. The overall cost is low and it is easy to process. The iron cup body 10 can be mass-produced by stamping, die-casting, etc., and is suitable for standardized manufacturing.

[0055] The transmission part 20 is responsible for sliding and linkage. The use of plastic material can effectively reduce the weight of the overall structure. The plastic surface is smooth, and the sliding cooperation with other structures is smoother. The friction is relatively small, and the inertia burden can be reduced, which is conducive to achieving light and sensitive damping response.

[0056] In this embodiment, the cup assembly, chassis assembly, and hinge arm of the pull-type cup head damping hinge are all independent modules, which can be separately disassembled and replaced with different specifications, and can be separately disassembled and replaced with structural parts of different specifications or parameters according to specific application requirements. It is convenient to flexibly select and match corresponding components for combined installation according to different requirements of door body size, opening and closing angle, installation space, or damping strength, significantly improving the adaptability range and market versatility of the hinge, and also facilitating later maintenance or upgrade and reducing replacement costs.
