Description

TECHNICAL FIELD

[0001] The utility model relates to a hinge, in particular to a lower buffering hardware hinge. BACKGROUND

[0002] As an important hardware fitting, hinges are widely used in furniture, cabinets, doors and windows, etc. to connect door leaves and door frames and realize opening and closing functions. With the increasing requirements of modern home design for aesthetics and user experience, the traditional hinge design has been difficult to fully meet market demand. In addition to the basic opening and closing function, consumers are increasingly concerned about whether the hinge can provide a soft closing effect to avoid noise and potential damage to the structure when the door leaf is quickly closed. Therefore, hinges with buffering function have gradually become the focus of industry development.

[0003] In the prior art, in order to realize the buffering effect of the hinge, the buffer is usually integrated in the hinge arm. This design can indeed achieve soft closing to some extent by absorbing impact force through the buffer during the closing process of the hinge. However, this technical solution of setting the buffer in the hinge arm has the following significant disadvantages:

[0004] 1. Large volume of hinge arm: In order to accommodate the buffer, the size of the hinge arm has to be designed larger. This increase in volume not only leads to an increase in material cost, but also significantly affects the overall aesthetics of the hinge. Especially in modern minimalist furniture design, space utilization and appearance delicacy are crucial, and a large volume of hinge arm is difficult to match with such design concept, limiting its application in the high-end furniture market.

[0005] 2. Complex installation: Integrating the buffer in the hinge arm usually requires designing a complex installation structure to fix the buffer, while the assembly precision is relatively high. This complexity increases the process difficulty and time cost in the production process, directly pushing up the manufacturing cost.

[0006] 3. Limited design flexibility: Fixing the buffer in the hinge arm limits the diversity of hinge design. For example, the shape and size of the hinge arm must be adjusted around the installation requirements of the buffer, which is difficult to adapt to different door leaf sizes or special customization needs. In the trend of increasing emphasis on individualization and diversification in the furniture market, this design lacks sufficient adaptability, reducing the market competitiveness of the product, so it is necessary to further improve it.

[0032] ​​The utility model discloses a kind of lower buffering hardware hinges, its core is to place buffering mechanism in the bottom cover 6 of hinge cup 1 bottom, linkage in sliding plate 7 by driving arm 31 on upper connecting rod 3, compression damper 8 generates damping force in closing process, realize soft closing;And in opening process, reset arm 32 and reset plate 74 push sliding plate 7 reset, ensure that damper 8 restores initial state.

[0033] When door leaf is closed, upper connecting rod 3 and lower connecting rod 4 between hinge cup 1 and hinge arm 2 swing relative to hinge cup 1 and hinge arm 2, push hinge to complete closing action.

[0034] Driving arm 31 on upper connecting rod 3 moves downward and inward, passes through the open slot 5 of the bottom of hinge cup 1, enters the bottom cover 6, and contacts with the abutting plate 72 on sliding plate 7.When hinge is closed to the set angle, driving arm 31 pushes abutting plate 72, so that sliding plate 7 does linear sliding along the guide slot 62 at the bottom of the containing cavity 61 in bottom cover 6.The movement of sliding plate 7 is further constrained by guide plate 73 and limiting slot 65 in bottom cover 6, to ensure stable trajectory.

[0035] Wherein, sliding plate 7 is connected with damper 8 installed in mounting hole 63 in bottom cover 6 through connecting arm 71 thereon.As sliding plate 7 slides, damper 8 is compressed, generates damping force, slows down the closing speed of hinge, and finally realizes soft closing of door leaf.

[0036] Wherein, open slot 5 penetrates the bottom of hinge cup 1, provides a channel for driving arm 31 to enter bottom cover 6.This design moves buffering mechanism to the bottom of hinge cup, avoids the increase of the volume of hinge arm, and maintains the compactness and aesthetics of hinge.

[0037] It should be noted that: bottom cover 6 covers the bottom of hinge cup 1 through containing cavity 61, and is fixed by elastic buckle 64 clamped into buckle hole 11 of hinge cup 1, which is simple and stable to install.The inside contains sliding plate 7 and damper 8, and modular design is convenient for maintenance and replacement.

[0038] Wherein, sliding plate 7 converts the rotary motion of driving arm 31 into linear compression of damper 8, abutting plate 72 ensures reliable connection with driving arm, and connecting arm 71 accurately transmits motion to damper.The sliding design ensures the stability of damping process, and improves the use reliability.

[0039] Wherein, damper 8 can be single-sided self-resetting compression damping type hydraulic damping cylinder, or bilaterally symmetrical, to provide different damping force, suitable for use in different door weight environment.

[0040] When the door leaf is opened, the upper link 3 and the lower link 4 swing reversely, the driving arm 31 of the upper link 3 is away from the pressing plate 72, and the pressure on the sliding plate 7 is reduced.

[0041] After the sliding plate 7 is reset, the buffer 8 is decompressed and restored under the self-resetting mechanism, and is ready for the next closing.

[0042] The reset arm 32 and the reset plate 74 constitute an automatic reset mechanism, which ensures that the sliding plate 7 and the buffer 8 are restored to the initial state when being opened, and are ready for the next closing.

[0043] Therefore, when the hinge is closed, the driving arm 31 of the upper link 3 pushes the sliding plate 7 through the opening slot 5, compresses the buffer 8 in the bottom cover 6, and generates a damping force to slow down the closing speed. When opened, the reset arm 32 pushes the reset plate 74, so that the sliding plate 7 and the buffer 8 are reset, and are ready for the next buffering.

[0044] Compared with the prior art, the buffer 8 is arranged in the bottom cover 6 at the bottom of the hinge cup 1, instead of being arranged in the hinge arm 2, so that the problem of the large size of the hinge arm due to the space occupied by the buffer is avoided. This design significantly reduces the external size of the hinge, makes the overall structure more compact, meets the high requirements of modern home design on space utilization and appearance delicacy, improves the appearance of the product, and therefore can be widely used.

[0045] The basic principle and main features of the utility model and the advantages of the utility model are shown and described. It should be understood by those skilled in the art that the utility model is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model can have various changes and improvements, and these changes and improvements all fall within the scope of the utility model.
