Description

Technical Field

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

[0002] Hydraulic soft-close hinges, commonly used in modern furniture and cabinets, function primarily to ensure smooth opening and closing of cabinet doors or panels. This effectively avoids noise and impact caused by rapid closing, extending the lifespan of the furniture. Traditional hinges often lack this soft-close feature, resulting in loud impact noise when closing cabinet doors and potentially pinching fingers. As consumers' demands for a superior home experience continue to rise, soft-close hinges have become the mainstream in the market.

[0003] In existing technologies, hydraulic buffer mechanisms are typically integrated inside the hinge to achieve the buffering function. However, existing hydraulic buffer hinges still have some shortcomings in their structural design.

[0004] In pursuit of a compact hinge design to fit into various narrow installation spaces, many designs tend to integrate the damping mechanism tightly into the hinge cup—the part of the hinge body used for mounting on the cabinet door. While this design philosophy helps reduce the space occupied by the hinge, a problem arises: when the cabinet door is open or the hinge is extended, the damping mechanism, originally hidden within the hinge cup, is often directly exposed. This not only detracts from the overall aesthetics of the hinge and affects the originally intricate furniture design, but the exposed damping mechanism is also more prone to dust accumulation or wear from the external environment, thus affecting its lifespan and damping effect. Therefore, further improvements are necessary. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a hydraulic buffer hinge linkage plate mounting structure that is simple in structure, easy to use, and can cleverly hide the buffer mechanism while ensuring that the hinge is compact and the buffer function is effective, thus avoiding its exposure and affecting the aesthetics. It also simplifies the installation and maintenance process and improves the overall performance of the product and the user experience.

[0006] The purpose of this utility model is achieved through the following means: a linkage plate mounting structure for a hydraulic buffer hinge, which includes a hinge cup and a hinge arm. The hinge cup and the hinge arm are hinged together by a first link and a second link. The hinge cup and the hinge arm rotate relative to the first link and the second link to realize the opening and closing of the hinge. The front end of the first link is provided with a linkage device, which is connected to a linkage plate provided at the bottom of the hinge cup. A damper is provided between the linkage plate and the hinge cup, and the damper slows down the movement speed of the linkage plate.

[0007] The hinge cup is also covered with a pressure plate, and a space is left between the pressure plate and the inner bottom of the hinge cup to form a receiving area, and the linkage plate slides within the receiving area.

[0008] Furthermore, the bottom of the pressure plate is provided with a guide groove, and the linkage plate is slidably installed in the guide groove.

[0009] Furthermore: the bottom of the pressure plate is provided with a downwardly extending positioning post, and the inner bottom of the hinge cup is provided with a positioning hole. After the pressure plate is installed, the positioning post extends into the positioning hole.

[0010] Furthermore, the outer contour of the pressure plate is provided with several positioning buckles, and correspondingly, the inner surface of the hinge cup is provided with several positioning grooves, and the positioning buckles are fixed in the positioning grooves.

[0011] Furthermore, the linkage device includes a buffer arm and a reset arm disposed at the front end of the first link, the buffer arm and the reset arm swinging around the hinge point between the first link and the hinge cup.

[0012] Furthermore, the linkage plate is provided with a buffer plate and a reset plate at the positions corresponding to the buffer arm and the reset arm, and the buffer plate and the reset plate are used to cooperate with the buffer arm and the reset arm.

[0013] Furthermore, the linkage plate is provided with a damping plate for connecting to the damper.

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

[0015] 2. In this case, a pressure plate is installed inside the hinge cup, forming a receiving area between the pressure plate and the inner bottom of the hinge cup, allowing the linkage plate to slide within this receiving area. This design effectively hides the entire linkage plate and its related linkage device under the pressure plate, making the furniture design simpler and more refined, avoiding the visual clutter caused by exposed mechanical parts, thereby improving the product's market competitiveness.

[0016] 3. In addition to its decorative and concealing functions, the pressure plate also cleverly positions and guides the linkage plate, thereby ensuring the smooth and reliable operation of the buffer mechanism and improving the stability of the buffering effect. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings. A linkage plate mounting structure for a hydraulic buffer hinge includes a hinge cup 1 and a hinge arm 2. The hinge cup 1 and the hinge arm 2 are hinged together by a first connecting rod 3 and a second connecting rod 4. The hinge cup and the hinge arm 2 rotate relative to the first connecting rod 3 and the second connecting rod 4 to open and close the hinge. A linkage device is provided at the front end of the first connecting rod 3, which connects to a linkage plate 7 located at the bottom of the hinge cup. A damper 8 is provided between the linkage plate 7 and the hinge cup 1 to slow down the movement speed of the linkage plate 7. A pressure plate 9 is also installed inside the hinge cup 1, leaving a gap between the pressure plate 9 and the bottom of the hinge cup 1 to form a receiving area 91. The linkage plate 7 slides within this receiving area 91. When the hinge opens and closes via the first connecting rod 3 and the second connecting rod 4, the front end of the first connecting rod 3 drives the linkage device to move relative to it. This linkage device then transmits the movement to the linkage plate 7. The linkage plate 7 is located in the receiving area 91 within the hinge cup 1 and can slide within this area. When the linkage plate 7 slides, it interacts with the damper 8 located between the hinge cup 1 and the linkage plate 7. The core function of the damper 8 is to slow down the movement speed of the linkage plate 7, thereby achieving a buffering effect on the hinge closing action. This allows the cabinet door to close smoothly, avoiding impact and noise.

[0023] It should be noted that by placing the linkage plate 7 within the receiving area 91 formed by the pressure plate 9 and the bottom of the hinge cup 1, the buffer linkage mechanism is effectively concealed. When the hinge is open, the pressure plate 9 covers the internal mechanical structure, greatly improving the overall aesthetics of the hinge and avoiding the disadvantage of exposed buffer mechanisms in traditional buffer hinges. This design not only achieves buffering functionality but also has a simpler and more upscale appearance.

[0024] In one embodiment, the bottom of the pressure plate 9 is provided with a guide groove 92, and the linkage plate 7 is slidably installed within the guide groove 92. Specifically, the bottom of the pressure plate 9 is provided with a guide groove 92, and the linkage plate 7 is precisely slidably installed within the guide groove 92. This ensures that the movement trajectory of the linkage plate 7 is strictly limited by the guide groove 92 throughout the entire buffering process, allowing it to move only along a preset straight or curved path. The introduction of the guide groove 92 ensures the accuracy and stability of the sliding of the linkage plate 7. It effectively prevents the linkage plate 7 from lateral swaying or jamming during movement, thereby ensuring that the damper 8 can continuously and smoothly provide buffering force. This precise guiding effect not only improves the reliability of the buffering effect but also extends the service life of the linkage plate and the damper, reducing the possibility of failure.

[0025] In one embodiment, the bottom of the pressure plate 9 is provided with a downwardly extending positioning post 93, and the inner bottom of the hinge cup 1 is provided with a positioning hole 11. After the pressure plate 9 is installed, the positioning post 93 extends into the positioning hole 11. When the pressure plate 9 is installed inside the hinge cup 1, these positioning posts 93 will be precisely inserted into the preset positioning holes 11 at the inner bottom of the hinge cup 1. This positioning structure provides a very precise installation position for the pressure plate 9. Through the cooperation of the positioning post 93 and the positioning hole 11, it can be ensured that the pressure plate 9 will not shift or rotate inside the hinge cup 1, thereby indirectly ensuring the correct alignment of the guide groove 92 and the linkage plate 7. This is crucial for the stability and reliable operation of the entire buffer mechanism, making the installation process simpler and faster, and also improving the assembly accuracy and overall structural stability of the product.

[0026] In one embodiment: a plurality of positioning buckles 94 are provided on the outer contour of the pressure plate 9, and correspondingly, a plurality of positioning grooves 12 are provided on the inner surface of the hinge cup 1. The positioning buckles 94 are fixed in the positioning grooves 12, thereby firmly fixing the pressure plate 9 inside the hinge cup 1.

[0027] This snap-fit ​​fixing method provides double or multiple securing measures for the pressure plate 9, ensuring its stability even in dynamic environments with frequent hinge opening and closing. More importantly, the snap-fit ​​fixing method is convenient to install and relatively easy to disassemble, which facilitates mass production and subsequent maintenance, reducing manufacturing costs and maintenance difficulty.

[0028] In one embodiment, the linkage device includes a buffer arm 5 and a reset arm 6 disposed at the front end of the first link 3. The buffer arm 5 and the reset arm 6 swing around the hinge point between the first link 3 and the hinge cup 1. When the hinge opens and closes, the first link 3 drives the buffer arm 5 and the reset arm 6 to swing around the hinge point between the first link 3 and the hinge cup 1. It is this swinging motion that converts the opening and closing motion of the hinge into pushing or pulling on the linkage plate 7, thereby driving the linkage plate 7 to slide within the receiving area 91 and working in conjunction with the damper 8.

[0029] This design ensures that the opening and closing motion of the hinge is reliably and efficiently transmitted to the cushioning mechanism. This integration of the cushioning process with the inherent motion pattern of the hinge results in a smooth and reliable cushioning effect.

[0030] In one embodiment, a buffer plate 71 and a reset plate 72 are provided on the linkage plate 7 corresponding to the positions of the buffer arm 5 and the reset arm 6, respectively. The buffer plate 71 and the reset plate 72 are used to cooperate with the buffer arm 5 and the reset arm 6. When the buffer arm 5 and the reset arm 6 swing, they will respectively engage with and interact with the buffer plate 71 and the reset plate 72 on the linkage plate 7, thereby pushing or pulling the linkage plate 7. This ensures the effectiveness and smoothness of force transmission. This precise cooperation helps reduce wear, improve transmission efficiency, and ensure that the buffering effect remains consistent throughout the hinge's lifespan.

[0031] In one embodiment: the linkage plate 7 is provided with a damping plate 73 for connection with the damper 8.

[0032] In summary, the core working principle of the hydraulic buffer hinge linkage plate mounting structure of this utility model is to convert the mechanical motion of the hinge opening and closing into the linear sliding motion of the linkage plate 7 through a linkage device, and to use the damper 8 to precisely control the speed of the sliding motion, thereby achieving a smooth buffering effect.

[0033] Specifically, when the hinge cup 1 and the hinge arm 2 open and close in conjunction with the linkage, the buffer arm 5 and the reset arm 6 at the front end of the first linkage will swing around their hinge point. These swing arms cooperate with the buffer plate 71 and the reset plate 72 on the linkage plate 7, respectively, thereby driving the linkage plate 7 to slide within the receiving area 91 inside the hinge cup 1.

[0034] The sliding path of the linkage plate 7 is precisely guided by the guide groove 92 set at the bottom of the pressure plate 9, ensuring the linearity and stability of its movement. During the sliding process, the damping plate 73 on the linkage plate 7 will connect and act with the damper 8. The damper 8 attenuates the movement speed of the linkage plate 7 through its internal mechanism, thereby making the opening and closing action of the hinge slow and smooth, avoiding impact and noise.

[0035] Furthermore, the pressure plate 9 plays a crucial role in the design to ensure the reliability and aesthetics of the buffer mechanism. It cleverly conceals the linkage plate 7 and its linkage mechanism by creating a receiving area 91 with the open space at the bottom of the hinge cup 1, solving the problem of the exposed buffer mechanism affecting aesthetics in existing technologies. Simultaneously, the pressure plate 9 achieves precise installation and secure fixation through the engagement of its bottom positioning post 93 with the positioning hole 11 of the hinge cup 1, and the engagement of its outer contour positioning buckle 94 with the positioning groove 12 of the hinge cup 1. This ensures the precise guiding effect of the guide groove 92 on the linkage plate 7.

[0036] Therefore, the technical solution of this utility model, by cleverly hiding the buffer mechanism under the pressure plate and combining it with precise positioning and guiding design, not only provides excellent buffering performance, but also shows significant technical advantages in terms of compact structure, aesthetics, ease of installation and service life.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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.
