[0006] Optionally, the transmission component has a groove, and the end of the damping rod extending out of the through-hole is provided with a insert, which is engaged in the groove.

[0007] Optionally, the transmission component is provided with a protrusion, and the protrusion has the groove.

[0008] Optionally, the surface of the cup body is recessed downward to form a cup rim and a cup protrusion. A baffle is provided on the side of the cup protrusion away from the cup rim. The baffle and the outer wall of the cup body cooperate to form a guide groove, which is used to accommodate the transmission component.

[0009] Optionally, the transmission member is provided with a guide block, which is used to be accommodated in the guide groove and slide along the guide groove.

[0010] Optionally, the guide groove includes a first guide groove and a second guide groove, the first guide groove and the second guide groove being located on opposite sides of the cup protrusion; The guide block includes a first guide block and a second guide block, wherein the first guide block is slidably installed in the first guide groove, and the second guide block is slidably installed in the second guide groove.

[0015] The embodiments of this application employing the above-described technical solution may have the following advantages: When the door is closed, the hinge retracts inward, and the transmission plate rotates towards the side closer to the cup. This causes the transmission plate to press against the transmission component and push it to move. As the transmission component moves, it pulls the damping rod outward, generating a damping force. This smooths the closing speed and reduces the impact and noise of closing the door. Furthermore, when the damping rod is pulled, the pressure change inside the damping component is relatively small, resulting in a more even force distribution and extending the service life of the damping component.

[0025] Hinges are widely used in various doors, windows, and storage cabinets, serving as connecting components between the door or window and the frame, providing support and rotation. In actual use, when a door or window closes, its own weight or external forces can cause it to close rapidly, generating significant impact and noise, which can lead to wear and breakage of the hinges or the door / window.

[0026] Based on the above, embodiments of this application provide a pull-type damping hinge cup and a pull-type cup-head damping hinge. This allows for a smooth closing speed, mitigating the impact and noise generated during door closing. See below for details.

[0027] 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.

[0028] Please see Figures 1 to 4 This application provides a pull-type damping hinge cup 100, which includes a cup body 10, a transmission component 20, a damping component 30, a rotating shaft, and a transmission plate 50, which will be described in detail below: The cup body 10 has a downwardly recessed surface forming a first receiving groove 11. An opening 12 is provided at the bottom side of the first receiving groove 11. The lower surface of the cup body 10 is provided with a closed receiving frame 15. One end of the receiving frame 15 is provided with a through-hole 151, which enables the cup body 10 to have a strong spatial integration capability, and can simultaneously accommodate rotating parts and damping parts, simplifying the overall structure and improving the compactness of the internal layout.

[0029] The transmission component 20 is slidably installed below the cup body 10. The transmission component 20 can slide relative to the cup body 10 in a predetermined direction. Its sliding fit can be adapted to the damping requirements of different stroke lengths. In some embodiments, multiple sliding responses can be achieved through structural adjustment, thereby enhancing the adjustment flexibility of the overall structure.

[0030] The damping element 30 is installed inside the receiving frame 15. The damping rod 31 of the damping element 30 extends along the through 151 and is fixedly connected to the transmission element 20. During maintenance, the damping element 30 can be directly removed from the receiving frame 15 and replaced.

[0031] The rotating shaft is connected across the first receiving groove 11. The rotating shaft serves as the rotation fulcrum of the transmission plate 50. Its position can be flexibly adjusted to adapt to transmission actions with different angles and stroke ranges, and it has good structural versatility.

[0032] 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 component 20, so that the transmission plate 50 can directly push or release the transmission component 20 during the opening and closing of the door, which facilitates the rapid realization of damping response and efficient transmission of force of the mechanism.

[0033] In this embodiment, the housing frame 15 has an opening 151 at only one end to enclose the damping element 30 inside, which can prevent most of the impurities such as dust, oil, and water vapor from entering, thereby improving the service life of the damping structure. In addition, the housing frame 15 can provide structural limit and support for the damping element 30, preventing it from shifting, 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.

[0034] In some embodiments, the receiving frame 15 can be disposed inside or outside the cup body; that is, the damping element 30 can be housed inside the cup body or hung outside the cup body. The installation position of the damping element 15 on the cup body is not specifically limited, as long as it can be pulled to generate a damping force when the door is closed. In some embodiments, the receiving frame 15 can also be formed by direct deformation of the side wall of the cup body.

[0035] The damping element 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 a clean appearance and compact structure.

[0036] Specifically, the receiving frame 15 is also provided with a sealing plate, which is connected to the edge of one end of the receiving frame 15 having an opening 151 and is bent inward to partially cover the opening 151. In actual assembly, the damping member 30 can be inserted into the receiving frame 15 along the opening 151 first, and then the sealing plate at the end of the opening 151 can be bent to completely limit the damping member 30 within the receiving frame 15, preventing the damping member 30 from falling out of the receiving frame 15. In some embodiments, the sealing plate can completely cover the opening 151, and an opening can be made in the sealing plate to allow the damping rod 31 to extend out.

[0037] In actual use, the hinge cup is fixed to the door body. When the door is closed, the hinge retracts inward as a whole, and the transmission plate 50 rotates towards the side closer to the cup body 10. This causes the transmission plate 50 to press against the transmission component 20 and push the transmission component 20 to move, resulting in relative movement between the transmission component 20 and the cup body. When the transmission component 20 moves, it pulls the damping rod 31 outward to generate a damping force, thereby smoothing the closing speed and reducing the impact and noise of closing the door. Furthermore, when the damping rod 31 is pulled, the pressure change inside the damping component 30 is relatively small, and the force is more evenly distributed, which can extend the service life of the damping component 30.

[0038] Furthermore, in this embodiment, the surface of the cup body 10 is concave downwards to form a cup rim 13 and a cup protrusion 14. A baffle 141 is provided on the side of the cup protrusion 14 away from the cup rim 13. The baffle 141, the outer wall of the cup protrusion 14, and the cup rim 13 cooperate to form a guide groove 143. The guide groove 143 is used to accommodate the transmission component 20. The guide groove 143 defines the sliding path of the transmission component 20, ensuring that it can slide smoothly in a predetermined direction and avoiding deflection or jamming.

[0039] Specifically, the guide groove 143 provides multi-faceted enclosure and limitation for the transmission component 20 in space, forming stable guiding control during its movement and avoiding swaying or deviation from the trajectory caused by excessive lateral clearance. Furthermore, the shape and depth of the guide groove 143 can be designed according to the size and stroke of the transmission component 20 to achieve high-precision fit, further improving the accuracy and durability of the sliding fit.

[0040] In addition, the baffle 141 can not only serve as a limiting structure for the transmission component 20, but also improve the structural strength of the edge of the cup body 10 to a certain extent, preventing deformation or breakage under transmission loading or door vibration, and enhancing the reliability and fatigue resistance of the overall hinge structure.

[0041] Specifically, the guide groove 143 can be naturally formed by the body structure of the cup 10, such as by integral molding or casting, reducing the number of parts and assembly processes. It eliminates the need for additional guide rails or guide structures, effectively reducing material costs and mold complexity, and facilitating mass production.

[0042] In addition, since the guide groove 143 and the cup body 10 are an integral structure, the accuracy and stability of the guide position can be ensured, and deviations caused by assembly errors or the accumulation of tolerances between parts can be avoided, which helps to improve the smoothness of the sliding process of the transmission component 20.

[0043] Furthermore, in an optional embodiment, the transmission member 20 is provided with a guide block 21, which is accommodated within the guide groove 143 and slides along the guide groove 143. The guide groove can restrict the sliding direction of the guide block 21, avoiding a decrease in transmission efficiency or structural jamming due to skewness, thereby ensuring the smoothness and reliability of the sliding block.

[0044] In some embodiments, to improve the guiding effect, the guide block 21 may be configured as a sliding column or sliding groove to form a relatively stable positioning and fitting relationship in the guide groove 143, effectively suppressing the lateral shaking or tilting deformation of the transmission component 20 during the sliding process.

[0045] In practical applications, the gap between the guide block 21 and the guide groove 143 can be matched with a tight gap or a gap fit, so that while ensuring the sliding flexibility, it has good guiding and positioning functions and enhances the operational stability of the structure.

[0046] In some embodiments, the inner wall of the guide groove 143 may also be lubricated or made of a low-friction coefficient material, such as by applying a coating or embedding a plastic guide rail, to further reduce sliding resistance and improve the overall mechanism's response sensitivity and service life.

[0047] In an optional embodiment, the guide groove 143 includes a first guide groove and a second guide groove, which are located on opposite sides of the cup protrusion 14. The guide block 21 includes a first guide block and a second guide block, wherein the first guide block is slidably mounted in the first guide groove, and the second guide block is slidably mounted in the second guide groove.

[0048] Specifically, the first and second guide grooves are distributed on both sides of the cup protrusion 14, allowing the two guide blocks 21 to be inserted into the guide grooves 143 on both sides, thus forming a double-point support sliding structure. This prevents the transmission component 20 from lateral swaying or tilting during sliding, making the sliding action smoother. Furthermore, the double-guide structure can achieve uniform load distribution during use, making the transmission component 20 less prone to deformation under stress and reducing the risk of damage.

[0049] In an optional embodiment, the transmission plate 50 is provided with a protruding plate 51 at the end near the bottom wall of the first receiving groove 11, and the transmission member 20 is provided with a stop portion 23, the protruding plate 51 extends along the opening 12 and abuts against the stop portion 23.

[0050] In actual use, when the hinge action (such as when the door closes) drives the transmission plate 50 to rotate, the convex plate 51 converts the rotation action into a thrust, and applies the thrust to the transmission member 20 through the contact stop part 23, thereby driving the transmission member 20 to slide along the guide groove 143, causing the transmission member 20 to pull the damping member 30 to generate a damping force.

[0051] Furthermore, the transmission component 20 has a groove 25, and the end of the damping rod 31 extending out of the through-hole 151 is provided with a insert 33, which is engaged within the groove 25. The groove 25 provides 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.

[0052] A sliding hole is provided on one side of the groove 25, which communicates with the groove 25. In actual installation, the insert 33 can be aligned with the groove 25, the damping rod 31 can be aligned with the sliding hole, and then the damping element 30 can be moved downward so that the damping rod 31 can slide downward along the sliding hole. At the same time, the insert 33 is engaged into the groove 25 to complete the assembly. The operation is simple and the installation process is efficient, requiring no additional tools or fasteners. If the damping element 30 needs to be replaced or repaired, the damping element 30 can be separated from the transmission element 20 simply by removing the insert 33 from the groove 25, without disassembling the hinge.

[0053] In an optional embodiment, the damping member 30 includes a first damping member and a second damping member, and the receiving frame 15 includes a first receiving frame and a second receiving frame. The first receiving frame and the second receiving frame are respectively fixed to opposite sides of the cup protrusion 14. The first receiving frame is used to receive the first damping member, and the second receiving frame is used to receive the second damping member. Both the first damping member and the second damping member are fixedly connected to the transmission member 20.

[0054] Both damping elements 30 are fixedly connected to the same transmission element 20 through their respective damping rods 31. The first damping element and the second damping element can synchronously generate damping effect on the transmission element 20. The damping force is superimposed, which can significantly improve the overall buffering capacity. For some larger or heavier door structures, it can ensure that the buffering is sufficient and the movement is smoother during the closing process.

[0055] Two damping elements 30 are symmetrically arranged on both sides of the transmission element 20. This symmetrical force distribution balances the sliding process of the transmission element 20, effectively preventing problems such as swaying, offset, and jamming caused by unilateral force, resulting in smoother sliding and more seamless operation. Furthermore, in some cases, if one damper fails, the other can still provide partial damping, providing redundant protection.

[0056] In an optional embodiment, the rim 13 is provided with a fixing hole 131, through which a fastener can pass and be fixedly connected to the door body, so that the hinge cup assembly is connected to the door body. Specifically, there can be multiple fixing holes 131, which can be located at the end corners of the rim 13. During installation, screws or other fasteners pass through the fixing holes 131 to firmly connect the cup body 10 to the inside of the door body, thereby achieving mechanical fixation between the hinge and the door body.

[0057] In this embodiment, the cup body 10 may be made of iron, and the transmission component 20 may be made of plastic.

[0058] The cup body 10 serves as the structural foundation directly fixed to the door. The use of iron material can effectively improve the overall load-bearing capacity and resistance to deformation. It can maintain a firm installation and is not easy to loosen or bend during long-term use. Moreover, the overall cost is low and it is easy to process. The iron cup body 10 can be mass-produced by stamping, die casting and other methods, making it suitable for standardized manufacturing.

[0059] The transmission component 20 is responsible for sliding and linkage. Using plastic material can effectively reduce the overall structural weight. The plastic surface is smooth, which makes the sliding cooperation with other structures smoother, the friction is relatively small, and the inertial load can be reduced, which is conducive to achieving a lightweight and sensitive damping response.

[0060] This application also provides a pull-type cup head damping hinge, which includes the pull-type damping hinge cup 100 described in any of the above claims.

[0061] Specifically, the pull-type cup-head damping hinge can also include a chassis assembly and a hinge arm. The pull-type damping hinge cup, chassis assembly, and hinge arm are all independent modules that can be disassembled and replaced with different specifications. This allows for individual disassembly and replacement of structural components with different specifications or parameters according to specific application requirements. This facilitates flexible selection and combination of appropriate components based on different requirements such as door size, opening angle, installation space, or damping strength, significantly improving the hinge's adaptability and market versatility. It also facilitates later maintenance or upgrades, reducing replacement costs.
