Description

Technical Field

[0001] This application belongs to the field of furniture hinge technology, and particularly relates to a damping hinge cup and a damping hinge. Background Technology

[0002] Hinges are widely used in furniture doors, equipment covers, and other structures. A typical hinge structure includes a hinge cup, a hinge arm, and a mounting base. The mounting base is directly mounted to the external structure with screws, and the hinge arm connects to the mounting base to achieve the opening and closing action.

[0003] However, existing door closing angles that generate damping force are usually fixed values, and cannot be adaptively adjusted according to the needs of actual use scenarios after the hinges are installed. For door panels of different weights and sizes, a fixed damping trigger angle is difficult to match the optimal buffering effect. At best, this leads to the door closing too quickly, causing the door panel / cover to collide hard with the cabinet or equipment body, resulting in component wear or noise; at worst, the damping intervention is too late, failing to effectively buffer the impact force and shortening the service life of the hinge and related structures.

[0004] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Summary of the Invention

[0005] This application provides a damping cup and a damping hinge to solve or alleviate one or more technical problems in the prior art.

[0006] The first aspect of this application provides a damping hinge cup, comprising: The cup body includes a base plate and two opposing side support structures, the two opposing side support structures being fixed to the same side of the base plate to form a groove; A movable plate is located on the base plate and slidably installed in the groove. The movable plate is provided with a first damping block and a second damping block. The length of the first damping block in the first direction is different from the length of the second damping block in the first direction. A damper is installed within any of the said side support structures, with a first end of the damper abutting the side support structure and a second end of the damper abutting the movable plate. An adjustment shaft is connected between the two side support structures; A damping adjustment block is slidably sleeved on the adjustment shaft, and the damping adjustment block is used to follow the rotation of the hinge arm; The damping adjustment block is used to slide to different positions of the adjustment shaft to correspond to the first damping block or the second damping block respectively, so that when the damping adjustment block follows the hinge arm to rotate to different angles, it abuts against the moving plate to drive the moving plate to slide, thereby pressing the damper to generate damping force.

[0007] Optionally, one end of the side support structure has an installation opening that communicates with a receiving cavity within the side support structure, the receiving cavity being used to accommodate the damper.

[0008] Optionally, the movable plate includes a plate body and an abutment portion, the abutment portion being fixed to one end of the plate body and used to abut against the second end of the damper.

[0009] Optionally, there are two dampers, and the two dampers are respectively installed in two opposite side support structures; There are two abutting parts, each corresponding to one of the two dampers, so as to abut the end of the damper corresponding to it.

[0010] Optionally, the base plate is provided with a first limiting protrusion and a second limiting protrusion spaced apart. The first limiting protrusion corresponds to the first side of the plate body, and the second limiting protrusion corresponds to the second side of the plate body. The first side and the second side of the plate body are arranged opposite to each other.

[0011] Optionally, the base plate is provided with a limiting block, which is located on the sliding path of the moving plate and is used to abut against the end of the moving plate.

[0012] Optionally, the damping hinge cup further includes a mounting portion connected to the side support structure. The mounting portion has a mounting hole for a connector to pass through, so as to fix the mounting portion to the external structure.

[0013] Optionally, the side support structure is provided with a removal groove, which is located at the upper edge of the side support structure.

[0014] A second aspect of this application provides a damping hinge, including a damping hinge cup as described in any of the preceding claims.

[0015] The embodiments of this application employing the above-described technical solution may have the following advantages: This application enables the selective sliding of the damping adjustment block to different positions on the adjustment shaft, allowing for the switching of different damping intervention angles within the same damping hinge cup structure. This allows for the selection of earlier or later damping intervention based on the door's weight, size, or usage scenario, resulting in a more suitable buffering effect during door closing. This alleviates problems such as limited hinge versatility and shortened lifespan caused by damping only being triggered at a fixed closing angle for door panels of different weights and sizes.

[0025] This application provides a damping hinge cup and a damping hinge. This addresses the problems of limited hinge versatility and shortened lifespan caused by the fact that damping can only be triggered at a fixed closing angle for door panels of different weights and sizes. Details are provided below.

[0026] 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.

[0027] Please see Figure 1 and Figure 2 This application provides a damping hinge cup, which includes a cup body, a movable plate 20, a damper 30, an adjusting shaft 40, and a damping adjusting block 50. The following is a detailed description: The cup body includes a base plate 11 and two opposing side support structures 12, which are fixed to the same side of the base plate 11 to form a groove.

[0028] The movable plate 20 is located on the base plate 11 and slidably installed in the groove. The movable plate 20 is provided with a first damping block 23 and a second damping block 24. The length of the first damping block 23 in a first direction is different from the length of the second damping block 24 in the first direction. Specifically, the first direction can be the direction from one side support structure 12 to another side support structure 12.

[0029] The damper 30 is installed in any of the side support structures 12, with the first end of the damper 30 abutting against the side support structure 12 and the second end of the damper 30 abutting against the movable plate 20.

[0030] The adjustment shaft 40 is connected between the two side support structures 12.

[0031] The damping adjustment block 50 is slidably sleeved on the adjustment shaft 40, and the damping adjustment block 50 is used to follow the rotation of the hinge arm.

[0032] The damping adjustment block 50 is used to slide to different positions of the adjustment shaft 40 to correspond to the first damping block 23 or the second damping block 24 respectively, so that when the damping adjustment block 50 follows the hinge arm to rotate to different angles, it abuts against the moving plate 20 to drive the moving plate 20 to slide, thereby pressing the damper 30 to generate damping force.

[0033] For example, when the damping adjustment block 50 slides to the first position, the damping adjustment block 50 corresponds to the first damping stop block 23. When the damping adjustment block 50 follows the hinge arm to rotate to the first preset angle (such as the angle between the door body and the door frame being 40°~50°), the damping adjustment block 50 abuts against the first damping stop block 23 to drive the moving plate 20 to slide, thereby pressing the damper 30 to generate a damping force. When the damping adjustment block 50 slides to the second position, the damping adjustment block 50 corresponds to the second damping stop 24. When the damping adjustment block 50 follows the hinge arm to rotate to the second preset angle (such as the angle between the door body and the door frame being 20°~30°), the damping adjustment block 50 abuts against the second damping stop 24 to drive the moving plate 20 to slide, thereby pressing the damper 30 to generate damping force.

[0034] This application eliminates the need to replace the damper 30 or the entire hinge structure. By selectively sliding the damping adjustment block 50 to different positions on the adjustment shaft 40, different damping intervention angles can be switched within the same damping hinge cup structure. This allows the damper 30 to intervene earlier or later depending on the door's weight, size, or usage scenario, resulting in a more suitable buffering effect during door closing. This alleviates problems such as limited hinge versatility and shortened lifespan caused by damping only being triggered at a fixed closing angle for door panels of different weights and sizes.

[0035] In an optional embodiment, one end of the side support structure 12 has an installation opening that communicates with a receiving cavity within the side support structure 12, the receiving cavity being used to accommodate the damper 30.

[0036] By providing an installation opening on the side support structure 12, the damper 30 can be inserted into or removed from the receiving cavity along the direction of the installation opening, improving assembly efficiency and maintenance convenience. Furthermore, the installation opening can be located near the outer side of the cup body for ease of assembly. After the damper 30 is inserted into the receiving cavity along the installation opening, the moving plate 20 is slidably installed in the groove, thus blocking both ends of the damper 30 and preventing it from falling off.

[0037] In an optional embodiment, the movable plate 20 includes a plate body 21 and an abutment portion 22, the abutment portion 22 being fixed to one end of the plate body 21, and the abutment portion 22 being used to abut against the second end of the damper 30. One end of the plate body 21 is provided with a first damping block 23 and a second damping block 24.

[0038] The abutment portion 22 serves as the direct force-bearing part between the moving plate 20 and the damper 30. During the sliding of the moving plate 20 along the groove, it stably transmits the thrust from the damping adjustment block 50 to the damper 30, thereby driving the damper 30 to generate damping force. By placing the abutment portion 22 at one end of the plate body 21, the force direction of the damper 30 can be aligned with the sliding direction of the moving plate 20.

[0039] In one embodiment, the abutment portion 22 may be configured as a locally thickened structure, a protruding structure, or an abutment structure with a preset curvature relative to the plate 21 to adapt to the end face shape of the second end of the damper 30, thereby ensuring reliable abutment while reducing the risk of local stress concentration and long-term wear, and improving the durability and service life of the damping hinge cup during repeated opening and closing.

[0040] In an optional embodiment, there are two dampers 30, each installed within one of the two opposing side support structures 12. There are also two abutment portions 22, each corresponding to one of the two dampers 30, abutting against the end of its corresponding damper 30.

[0041] By installing dampers 30 in the two opposing side support structures 12 and providing two corresponding abutment parts 22 on the moving plate 20, the moving plate 20 can simultaneously or nearly simultaneously apply forces to the two dampers 30 during sliding, thus forming a symmetrical damping force structure. This effectively avoids the displacement, tilting, or jamming of the moving plate 20 caused by unilateral force, improving the smoothness and reliability of the sliding process of the moving plate 20.

[0042] The two dampers 30 work together to provide damping, which can improve the overall damping capacity without significantly increasing the load on a single damper 30. This makes the damping force distribution more uniform, which is beneficial for adapting to door structures with larger weight or size, and reduces the risk of fatigue and wear caused by long-term load on a single damper 30.

[0043] It is understandable that the arrangement of the dual dampers 30 and dual contact parts 22 is an enhancement scheme for the damping capacity and structural stability of the damping hinge cup. While maintaining the damping intervention angle adjustment function, it further improves the applicability and service life of the device under high-frequency opening and closing or heavy-load conditions.

[0044] By setting a first limiting protrusion 111 and a second limiting protrusion 112 on the base plate 11 and making them correspond to the two sides of the plate 21, the plate 21 can be laterally guided and limited during the sliding of the moving plate 20 along the slide groove, thereby preventing the moving plate 20 from shifting laterally or tilting during the sliding process and improving the smoothness and reliability of the sliding.

[0045] In addition, the first limiting protrusion 111 and the second limiting protrusion 112 can also serve as alignment references during the assembly process, enabling the moving plate 20 to be quickly positioned when installed into the slide groove, reducing assembly errors and improving assembly efficiency.

[0046] In an optional embodiment, the base plate 11 is provided with a limiting block 114, which is located on the sliding path of the moving plate 20 and is used to abut against the end of the moving plate 20.

[0047] The limiting block 114 can be used to limit the maximum sliding stroke of the moving plate 20 in the slide groove. When the moving plate 20 abuts against the limiting block 114, it can prevent the moving plate 20 from sliding out of the slide groove or sliding excessively, thereby ensuring the accuracy of the force position of the damper 30.

[0048] The limiting block 114 can provide a buffer contact surface when the moving plate 20 reaches the end of the sliding, thereby reducing the impact caused by the direct collision between the moving plate 20 and the base plate 11 or other structural components, reducing wear and noise, and improving the durability of the damping hinge cup during long-term use.

[0049] Furthermore, a guide groove can be formed on the plate 21. During the sliding process of the moving plate 20, the limiting block 114 is always located within the guide groove to achieve trajectory control of the moving plate 20 during the sliding process, ensuring that the plate 21 slides in a predetermined direction without deviation or tilting. Specifically, the limiting block 114 is detachably installed on the base plate 11. During installation, the movable plate 20 can be slid into the groove first, and then the limiting block 114 can be installed on the base plate 11, thereby avoiding the problem of the limiting block 114 interfering with the movable plate 20 when the movable plate 20 is installed.

[0050] In an optional embodiment, the damping hinge cup further includes a mounting portion 60, which is connected to the side support structure 12. The mounting portion 60 is provided with a mounting hole 61 for a connector to pass through, so as to fix the mounting portion 60 to an external structure, which may be a door, such as a glass door.

[0051] Mounting part 60 provides a stable fixing point for the damping hinge cup, enabling it to be reliably installed on the external structure, thereby ensuring that the moving plate 20 and the damper 30 can work normally during the opening and closing of the door.

[0052] Furthermore, the mounting part 60 can be matched with the shape of the external structure to achieve a fitting, thereby improving the installation stability of the damping hinge cup on the door or other external structure, enhancing the fixing reliability, and reducing shaking or loosening caused by installation gaps or changes in force.

[0053] In an optional embodiment, the side support structure 12 is provided with a removal groove 123, which is located at the upper edge of the side support structure 12.

[0054] The removal slot 123 makes it easier to access the moving plate 20 or damper 30 during installation or maintenance, thereby simplifying the operation steps and reducing tool interference and operation difficulty during disassembly.

[0055] Specifically, in some embodiments, the damping hinge cup is embedded in the door body after installation, and the removal groove 123 can provide a point of leverage for disassembly, allowing operators to apply force to the hinge cup embedded in the door body with their fingers, tools or special operating parts, thereby conveniently removing it and improving the safety and efficiency of maintenance and replacement.

[0056] This application also provides a damping hinge, including the damping hinge cup described in any of the above claims.

[0057] Please see Figure 3 The damping hinge may also include a hinge arm 200 and a mounting base 300. The mounting base 300 is used to connect with structures such as cabinets and walls to provide a stable installation reference point and support for the hinge.

[0058] The hinge arm 200 is rotatably connected between the damping hinge cup 100 and the fixed seat 300, so that the hinge can drive the moving plate of the damping hinge cup 100 to slide during the opening and closing of the door or cabinet, thereby generating damping force through the damper to achieve opening and closing buffer.

[0059] In an optional embodiment, the damping adjustment block is provided with a positioning block (not shown in the figure), and the hinge arm 200 is provided with a first positioning groove 201 and a second positioning groove 202. The damping adjustment block can slide to the corresponding position so that the positioning block is engaged in the first positioning groove 201 or the second positioning groove 202, thereby enabling the damping adjustment block to slide accurately to the predetermined position during installation or adjustment, thereby achieving reliable alignment with the first damping stop or the second damping stop.

[0060] The positioning block and the first positioning groove / second positioning groove can provide a preset position for the damping adjustment block after movement, so that the damping adjustment block can be accurately positioned when sliding and adjusting, which facilitates the preset adjustment of the damping trigger angle. Thus, the damping angle can be preset according to different door weights or sizes, improving the adaptability and flexibility of the damping hinge cup 100.

[0061] It should be noted that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application.
