Description

Technical Field

[0001] This utility model relates to the field of hardware hinge technology, specifically a damper mounting structure for a hydraulic buffer hinge. Background Technology

[0002] Hydraulic damping hinges are widely used in home and office furniture due to their smooth and silent closing effect. The core component of this type of hinge is the damper, which slows down the closing speed of the door or cabinet through damping, avoiding impact and noise.

[0003] However, existing hydraulic buffer hinges generally have the following drawbacks in the installation structure of the buffer:

[0004] Currently, hydraulic damping hinges on the market typically install their dampers inside the hinge cup. Due to the structural size limitations of the hinge cup itself, its internal space is often very narrow. This space constraint necessitates the use of costly and highly precision-manufacturing miniature dampers in existing technologies.

[0005] While these miniature dampers can achieve a cushioning function within a limited space, they also bring significant technical drawbacks. Specifically, these miniature dampers generally suffer from low cushioning force and short cushioning stroke. This means that they are ineffective at cushioning heavier door panels or larger impacts, easily leading to door panel rebound or incomplete cushioning. Furthermore, due to their precise and miniaturized internal structure, these dampers also have a relatively short lifespan, are prone to wear and oil leaks, and thus affect the overall performance of the hinge and the user experience. Therefore, further improvements are necessary. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a hydraulic buffer hinge buffer installation structure that is simple in structure, easy to use, and can solve the buffer installation problem in the prior art, improve buffer performance and service life, and reduce costs.

[0007] The purpose of this utility model is achieved through the following means: a damper mounting structure for a hydraulic buffer hinge, characterized in that: it includes a hinge cup, an mounting area is recessed in the outer side wall of the hinge cup, and a mounting hole is opened through the inner and outer sides of the mounting area, and the damper is installed in the mounting hole.

[0008] A protective cover is embedded in the installation area, and a positioning hole is provided in the protective cover. The cylinder part of the buffer is fixed in the positioning hole, and the piston rod of the buffer passes through the installation hole and is connected to the linkage plate provided in the hinge cup.

[0009] Furthermore: the mounting area is fan-shaped and is formed by stamping the hinge cup body material from the outside to the inside.

[0010] Furthermore: the mounting hole sidewall is provided with a docking hole, and the protective cover is provided with a docking post. One end of the protective cover is inserted into the docking hole through the docking post for installation and fixation.

[0011] Furthermore, the protective cover is also provided with a connecting buckle, and correspondingly, the side wall of the mounting hole is also provided with a connecting hole. When the protective cover is installed, the connecting buckle is locked in the connecting hole for fixation.

[0012] Furthermore, the protective cover is also provided with a clearance groove, through which a connecting pin passes and connects to the hinge cup, and the connecting pin fixes the protective cover in the installation area.

[0013] Furthermore, the protective cover is configured in a fan shape, similar in shape to the installation area.

[0014] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0015] 2. By recessing the mounting area and providing mounting holes in the side wall of the hinge cup, more space is provided for the installation of the buffer. This allows the use of larger, higher-performance buffers, thereby significantly improving the buffering force and extending the buffer stroke.

[0016] 3. Larger buffers typically mean a more robust structure and lower internal pressure, which will greatly extend the buffer's lifespan and reduce failure rates and maintenance costs.

[0017] 4. The cylinder part of the shock absorber is fixed in the positioning hole inside the protective cover, which provides a stable installation and reduces the shaking and wear of the shock absorber during use.

[0018] 5. By eliminating the limitations of the narrow space inside the hinge cup, this technical solution no longer mandates the use of high-cost, high-precision miniature dampers. This allows manufacturers to choose lower-cost, higher-performance standard dampers, thereby significantly reducing the overall manufacturing cost of the hydraulic damping hinge.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings. A damper mounting structure for a hydraulic buffer hinge is characterized by comprising a hinge cup 1, an mounting area 2 recessed in the outer side wall of the hinge cup 1, and mounting holes 3 extending through the hinge cup 1. The damper 4 is mounted within the mounting holes 3. A protective cover 6 is embedded within the mounting area 2, and a positioning hole 61 is provided within the protective cover 6. The cylinder portion 42 of the damper 4 is fitted and fixed within the positioning hole 61. The piston rod 41 of the damper 4 passes through the mounting hole 3 and connects to a linkage plate 5 disposed within the hinge cup 1.

[0024] In this embodiment, when the door panel or cabinet is closed, the movement of the hinge causes the connecting rod on the hinge and the linkage plate 5 set in the hinge cup 1 to drive the piston rod 41 of the buffer 4 to move axially. The piston rod 41 passes through the mounting hole 3 and transfers the kinetic energy of the door panel closing to the buffer 4, using the damping effect of the buffer to provide damping force for the hinge to close.

[0025] The buffer 4 is cleverly installed within the mounting hole 3 in the recessed mounting area 2 on the side wall of the hinge cup 1. To ensure the stability of the buffer 4, a protective cover 6 is fitted into the mounting area 2, and the positioning hole 61 inside the protective cover 6 fits tightly with the cylinder part 42 of the buffer 4, achieving precise positioning and reliable fixation of the buffer 4. This design provides ample installation space for the buffer, overcoming the limitations of narrow internal space in traditional hinges.

[0026] The design of the mounting area and mounting holes allows the damper to be installed in the recessed area outside the hinge cup, effectively utilizing space and solving the problem of limited space for damper installation inside the hinge cup in existing technologies. The larger installation space allows for the use of larger, more powerful, and longer-lasting dampers, resulting in a more ideal damping effect, such as greater damping torque and longer damping stroke. Simultaneously, the positioning holes 61 of the protective cover 6 securely fasten the cylinder body portion 42 of the damper 4, ensuring the stability and reliability of the damper during operation and reducing performance degradation or damage caused by loosening.

[0027] In one embodiment, the mounting area 2 is fan-shaped and is stamped from the outside to the inside of the hinge cup 1 body material. The fan-shaped design of the mounting area 2 allows it to better integrate with the circular or arc-shaped sidewalls of the hinge cup 1, saving material and making the overall structure more compact and aesthetically pleasing. Furthermore, stamping from the outside to the inside of the hinge cup 1 body material means that the mounting area 2 is not manufactured separately and then assembled, but rather integrally formed directly from the hinge cup 1 material through a stamping process. Stamping is a highly efficient manufacturing process that helps reduce production costs and improve production efficiency. At the same time, the integrally formed structure avoids additional connecting parts, reducing welding or riveting steps, thereby resulting in a stronger connection between the mounting area and the hinge cup body, making it less prone to loosening or damage.

[0028] In one embodiment: the mounting hole 3 has a mating hole 31 on its side wall, and the protective cover 6 has a mating post 62. One end of the protective cover 6 is inserted into the mating hole 31 through the mating post 62 for installation and fixation.

[0029] By setting a mating hole 31 on the side wall of the mounting hole 3 and setting a corresponding mating post 62 on the protective cover 6, the mating post 62 at one end of the protective cover 6 can be accurately inserted into the mating hole 31 on the side wall of the mounting hole 3 during installation.

[0030] This plug-in connection provides an initial positioning and fixing point for the protective cover 6, ensuring its correct position within the installation area 2 and enabling it to withstand a certain axial force.

[0031] The mating post and mating hole provide clear guidance, making the installation of the protective cover simple and quick, without the need for complex alignment. At the same time, the plug-in structure ensures the precise installation position of the protective cover, thereby guaranteeing a good fit between the internal positioning hole 61 of the protective cover and the cylinder body part 42 of the shock absorber 4.

[0032] In one embodiment, the protective cover 6 is further provided with a connecting buckle 63, and the side wall of the mounting hole 3 is provided with a connecting hole 32. The connecting buckle 63 is snapped into the connecting hole 32 for fixation. By providing the connecting buckle 63 on the protective cover 6 and providing a corresponding connecting hole 32 on the side wall of the mounting hole 3, when the protective cover 6 is installed in place, the connecting buckle 63 can snap into the connecting hole 32, forming a flexible snap-fit ​​connection. This snap-fit ​​connection provides a quick, tool-free fixing method, significantly improving assembly efficiency. At the same time, it simplifies the operation steps and reduces the skill requirements for operators.

[0033] In one embodiment, the protective cover 6 is further provided with a clearance groove 64, through which the connecting pin 7 passes and connects to the hinge cup 1, and the connecting pin 7 fixes the protective cover 6 in the mounting area 2.

[0034] This method of securing the protective cover with connecting pins typically provides a very reliable and robust connection, especially suitable for applications requiring high loads or long-term stability. The recessed groove 64 ensures that the connecting pin 7 can pass through smoothly and perform its securing function, while also potentially providing operating space for pin installation. The pin connection provides extremely high shear strength and connection stiffness, ensuring the long-term stable fixation of the protective cover.

[0035] In one embodiment, the protective cover 6 is shaped like a fan, similar in shape to the mounting area 2. This allows the protective cover 6 to be perfectly embedded into the fan-shaped mounting area 2, forming a tightly fitting whole. This fan-shaped design not only ensures the geometric matching between the protective cover 6 and the mounting area 2, but also further optimizes space utilization and may simplify mold design and manufacturing processes, improving the overall structural stability and aesthetics.

[0036] In summary, the core working principle of the hydraulic buffer hinge damper mounting structure disclosed in this utility model lies in the following: a fan-shaped mounting area 2 is cleverly formed by recessing the side wall of the hinge cup 1, and a mounting hole 3 is provided within it, providing a spacious and externally accessible mounting position for the damper 4. This design fundamentally solves the drawback of existing technologies where dampers must use high-cost, low-performance micro-dampers due to the narrow internal space of the hinge cup. This allows the present utility model to accommodate larger, higher-performance dampers, thereby significantly improving the buffering force, extending the buffering stroke, and increasing the service life.

[0037] To ensure the stable installation of the buffer 4, this invention introduces a fan-shaped protective cover 6, which is tightly fitted into the mounting area 2. The positioning hole 61 inside the protective cover 6 precisely fits and fixes the cylinder part 42 of the buffer 4, ensuring the stability and reliability of the buffer during operation. At the same time, the piston rod 41 of the buffer 4 passes through the mounting hole 3 and connects to the linkage plate 5 inside the hinge cup 1, converting the movement of the hinge into the damping effect of the buffer.

[0038] Furthermore, this invention provides multiple flexible and reliable methods for fixing the protective cover 6, including positioning and installation by inserting the docking post 62 into the docking hole 31, quick fixing by snapping the connecting buckle 63 into the connecting hole 32, or connecting the connecting pin 7 through the clearance groove 64 to the hinge cup 1 to provide extremely high fixing strength. These diverse fixing methods not only improve the convenience and efficiency of installation, but also ensure the stability of the protective cover in different application scenarios, further enhancing the reliability of the entire buffer installation structure.

[0039] In summary, this utility model, by optimizing the installation space of the buffer, adopting a stable protective cover fixing mechanism, and providing a variety of convenient fixing solutions, ultimately achieves a comprehensive improvement in the performance, cost, installation convenience, and structural reliability of the hydraulic buffer hinge, and therefore can be widely promoted and used.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
