Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware accessories technology, specifically to a hinge cup damper mounting structure and hinge. Background Technology
[0002] Damping hinges are a core component in modern furniture, enabling cabinet doors to close smoothly and silently. Currently, integrating dampers into hinges to achieve a cushioning function has become an industry standard. However, depending on the overall hinge design, there are two main technical approaches to the installation location of the damper.
[0003] In existing technologies, some hinges mount the damper on the hinge arm. This layout often relies on long transmission links or complex lever mechanisms to trigger the damper, potentially resulting in a bulky hinge arm structure and multiple connection points between moving parts, increasing instability and wear risks during movement. While some hinges mount the damper within the hinge cup, which contributes to overall hinge compactness, current designs rely on independent brackets and clips for damper installation and fixation, resulting in numerous parts and complex assembly. Furthermore, the damper is prone to loosening under prolonged stress, affecting its cushioning effect. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a hinge cup damper mounting structure and hinge that is simple in structure, reliable in performance, and has a long service life.
[0005] In a first aspect, the hinge cup damper mounting structure provided by this utility model includes: a hinge cup, a sliding plate, and a damper; The hinge cup includes a mounting base, which has an integrally formed base plate and a mounting block. The mounting block is provided with a mounting groove, and the mounting base is also provided with a slide for limiting the sliding plate. The sliding plate is slidably installed in the slide rail, and the damper is installed in the mounting groove. The damper is connected to the sliding plate.
[0006] Furthermore, the base plate is equipped with buckles, and the gap between the buckles and the base plate forms a slide for the limiting sliding plate.
[0007] Furthermore, the sliding plate is provided with a limit groove corresponding to the buckle, and the buckle and the limit groove are connected in cooperation.
[0008] Furthermore, there are two mounting blocks, which are positioned opposite each other on both sides of the base plate. The two mounting blocks and the base plate form a sliding groove, and a sliding plate is located in the sliding groove.
[0009] Furthermore, the damper is a hydraulic buffer damper, with at least part of the cylinder body of the damper located in the mounting groove, and the piston rod of the damper connected to the sliding plate.
[0010] Furthermore, the sliding plate is provided with a connecting plate, which abuts against the piston rod.
[0011] Furthermore, the mounting block is provided with a guide groove for limiting the sliding direction of the sliding plate, and the piston rod and connecting plate are located in the guide groove.
[0012] Furthermore, the base plate is also provided with a limit block, the sliding plate has a limiting part, the limit block is located on the movement path of the limiting part, and the limit block cooperates with the limiting part to limit the movement stroke of the sliding plate.
[0013] Furthermore, the hinge cup also includes a cup body, which is located on the side of the sliding plate away from the mounting base to shield and cover the mounting base and the sliding plate.

Detailed Implementation
[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0019] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0020] like Figure 1-5 As shown, the hinge cup damper mounting structure provided in this embodiment includes a hinge cup 1, a sliding plate 2, and a damper 3.
[0021] The hinge cup 1 includes a mounting base 11, which has an integrally formed base plate 111 and a mounting block 112. The mounting block 112 is provided with a mounting groove 1121, and the mounting base 11 is also provided with a slide rail 12 for limiting the sliding plate 2.
[0022] The sliding plate 2 is slidably installed in the slide rail 12, and the damper 3 is installed in the mounting groove 1121. The damper 3 is connected to the sliding plate 2.
[0023] By mounting the damper 3 within the hinge cup 1 using the mounting base 11, the volume of the hinge arm 4 can be reduced, thereby reducing the overall volume of the hinge. Simultaneously, the base plate 111 and mounting block 112 of the mounting base 11 are manufactured using an integrated molding process, ensuring structural strength and dimensional accuracy between the base plate 111 and the mounting block 112, and reducing the assembly process. The damper 3 is placed within the mounting groove 1121 of the mounting block 112. One end of the sliding plate 2 is connected to the damper 3, and the other end of the sliding plate 2 is driven to slide, causing the damper 3 to achieve smooth buffering and resetting movements. This simplifies the installation structure of the damper 3, ensures reliable performance, and extends the service life of the hinge.
[0024] It should be noted that the number of mounting blocks 112 can be one, with one mounting block 112 set on one side of the base plate 111. A limiting plate can be set on the side of the mounting block 112 closest to the base plate 111, and the gap between the limiting plate and the base plate 111 forms the slide rail 12 of the limiting sliding plate 2. Alternatively, the number of mounting blocks 112 can be two, with two mounting blocks 112 set opposite to each other on opposite sides of the base plate 111. The two mounting blocks 112 and the base plate 111 together enclose and form the slide rail 12 of the limiting sliding plate 2.
[0025] Furthermore, a latch 1111 is provided on the base plate 111, and the gap between the latch 1111 and the base plate 111 forms a slide rail 12 for limiting the sliding plate 2. The latch 1111 extends from the base plate 111 towards the middle of the sliding plate 2, and the sliding plate 2 is disposed in the gap between the latch 1111 and the base plate 111, and can slide along the gap. The latch 1111 can effectively limit the sliding plate 2, ensuring that the sliding plate 2 does not deviate from the preset trajectory during movement, thus improving movement stability.
[0026] Furthermore, the sliding plate 2 is provided with a limiting groove 21 corresponding to the buckle 1111, and the buckle 1111 is connected to the limiting groove 21. Specifically, the hook of the buckle 1111 is set in the limiting groove 21. During the sliding process of the sliding plate 2, the hook slides relative to the limiting groove 21, which restricts the sliding direction of the sliding plate 2, thereby further enhancing the guiding accuracy of the sliding plate 2 and preventing it from deviating or shaking during the sliding process.
[0027] Furthermore, two mounting blocks 112 are provided, which are positioned opposite each other on both sides of the base plate 111. The two mounting blocks 112 and the base plate 111 form a sliding groove, and the sliding plate 2 is disposed in the sliding groove. By providing a mounting block 112 on each opposite side of the base plate 111, the sliding plate 2 can be damped by the damper 3 on both sides, resulting in uniform force distribution. This further prevents deviation during sliding, making the movement more stable and reliable while extending the service life of the sliding plate 2.
[0028] Furthermore, the damper 3 is a hydraulic buffer damper, with at least a portion of the cylinder 31 of the damper 3 located within the mounting groove 1121, and the piston rod 32 of the damper 3 connected to the sliding plate 2. The hydraulic buffer damper has the advantages of efficient energy absorption, smooth deceleration, long service life, and low noise, which can improve the overall performance of the hinge.
[0029] It is understandable that damper 3 can also be a spring buffer, a pneumatic buffer, or other dampers, and the appropriate choice can be made according to actual needs and specific scenarios.
[0030] Furthermore, the sliding plate 2 is provided with a connecting plate 22, which abuts against the piston rod 32. Specifically, the end of the sliding plate 2 near the piston rod 32 is provided with a connecting plate 22 extending toward the piston rod 32, which abuts against the piston rod 32, thereby driving the piston rod 32 to retract into the cylinder when the sliding plate 2 slides, thus triggering a damping effect.
[0031] It is understandable that the connection between the connecting plate 22 and the piston rod 32 can also be achieved through a pin connection or other forms of connection; the connection between the sliding plate 2 and the piston rod 32 can also be achieved through other forms, such as snap-fit or plug-in.
[0032] Furthermore, the mounting block 112 is provided with a guide groove 1122 for limiting the sliding direction of the sliding plate 2, and the piston rod 32 and the connecting plate 22 are disposed in the guide groove 1122. The guide groove 1122 can constrain the movement path of the piston rod 32 and the connecting plate 22, preventing the sliding plate 2 from getting stuck during the sliding process.
[0033] Furthermore, the base plate 111 is also provided with a limiting block 1112, and the sliding plate 2 has a limiting part. The limiting block 1112 is located on the movement path of the limiting part, and the limiting block 1112 cooperates with the limiting part to limit the movement stroke of the sliding plate 2. When the sliding plate 2 moves to the preset position, the limiting part abuts against the limiting block 1112, thereby limiting the stroke of the sliding plate 2 and preventing the sliding plate 2 from excessively compressing the damper 3 or disengaging from the slide rail 12.
[0034] Furthermore, the hinge cup 1 also includes a cup body 13, which is located on the side of the sliding plate 2 away from the mounting base 11 to cover the mounting base 11 and the sliding plate 2. The cup body 13 covers the mounting base 11 and the sliding plate 2, serving both protective and aesthetic purposes. The hinge cup 1 can be connected to the cabinet door through the cup body 13.
[0035] For example, the mounting base 11 may be provided with a pin, and the cup body 13 may be provided with a pin hole. The mounting base 11 and the cup body 13 are connected by the pin. The mounting base 11 and the cup body 13 may also be connected in other ways.
[0036] like Figure 6 As shown, this utility model also provides a hinge, including a hinge cup damper mounting structure, a hinge arm 4 and a base 5 of any of the above embodiments. The hinge cup 1 and the base 5 are hinged by the hinge arm 4. The hinge arm 4 is hinged to the hinge cup 1 and abuts against the end of the sliding plate 2 away from the damper 3 during the hinge closing process to drive the sliding plate 2 to slide.
[0037] The working principle of this utility model is as follows: When the cabinet door is closed, the hinge arm 4 rotates with the cabinet door, contacts one end of the sliding plate 2, and pushes it to slide along the slide rail 12. The movement of the sliding plate 2 is transmitted to the piston rod 32 of the damper 3 through the connecting plate 22, causing it to retract into the cylinder 31. The hydraulic damping effect generates a buffering force, realizing a slow and smooth closing action. When the cabinet door is opened, the piston rod 32 resets, driving the sliding plate 2 back to its initial position, preparing for the next closing.
[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
