Description

Technical Field

[0001] The invention relates to a hinge, in particular to a lower buffer hardware hinge. Background Art

[0002] As an important hardware accessory, hinges are widely used in furniture, cabinets, doors and windows, etc. to connect door panels and door frames and realize opening and closing functions. As modern home design has higher requirements for aesthetics and user experience, traditional hinge designs can no longer fully meet market demand. In addition to the basic opening and closing functions, consumers are increasingly concerned about whether hinges can provide a soft closing effect to avoid noise and potential damage to the structure when the door panels are closed quickly. Therefore, hinges with buffering functions have gradually become the focus of industry development.

[0003] In the prior art, in order to achieve the buffering effect of the hinge, the buffer is usually integrated inside the hinge arm. This design can indeed achieve a certain degree of soft closing by absorbing the impact force during the hinge closing process through the buffer. However, this technical solution of placing the buffer inside the hinge arm has the following significant disadvantages: 1. The hinge arm is bulky: In order to accommodate the buffer, the hinge arm has to be designed to be larger. This increase in size not only leads to an increase in material costs, but also significantly affects the overall aesthetics of the hinge. Especially in modern minimalist style furniture design, space utilization and appearance refinement are crucial, and the bulky hinge arm is difficult to match this kind of design concept, limiting its application in the high-end furniture market.

[0004] 2. Complex installation: Integrating the buffer inside the hinge arm usually requires the design of a complex installation structure to fix the buffer, and requires high assembly accuracy. This complexity increases the difficulty and time cost of the production process, directly pushing up the manufacturing cost.

[0005] 3. Limited design flexibility: Fixing the buffer inside 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 requirements. With the furniture market increasingly emphasizing personalization and diversification, this design lacks sufficient adaptability and reduces the market competitiveness of the product, so it is necessary to make further improvements to it. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a lower buffering hardware hinge with simple structure, low manufacturing cost, small size, neat and beautiful appearance.

[0007] The object of the present invention is achieved in the following manner: a lower buffer hardware hinge, which includes a hinge cup and a hinge arm, the hinge cup and the hinge arm are hingedly installed through an upper connecting rod and a lower connecting rod, the upper connecting rod and the lower connecting rod swing relative to the hinge cup and the hinge arm to realize the opening and closing of the hinge, and the bottom of the hinge cup is provided with an open groove penetrating through its body; The bottom of the hinge cup is covered with a bottom cover, and a slide plate is slidably installed in the bottom cover; A buffer is also installed in the bottom cover, and the buffer is connected to the slide plate; The upper connecting rod is provided with a driving arm, which extends into the bottom cover and is connected with the slide plate. When the hinge is closed, the driving arm pushes the slide plate to compress the buffer, thereby generating a damping effect when the hinge is closed.

[0008] Furthermore: the top of the bottom cover is concave downward to form a receiving cavity, and the bottom of the hinge cup is covered and fixed in the receiving cavity.

[0009] Furthermore: a guide groove is provided at the bottom of the accommodating cavity, and the slide plate is slidably installed in the guide groove.

[0010] Furthermore: a mounting hole is provided in the bottom cover, the buffer is installed in the mounting hole, and a connecting arm is provided on the slide plate, and the connecting arm is connected to the buffer.

[0011] Furthermore: elastic buckles are provided on both sides of the bottom cover extending toward the hinge cup, and correspondingly, buckle holes are provided on the hinge cup, and the bottom cover is inserted into the buckle holes through the elastic buckles to be connected and fixed thereto as a whole.

[0012] Furthermore: the buffer is arranged on one side of the slide plate, and the buffer is a self-resetting compression damping type hydraulic damping cylinder.

[0013] Furthermore: two buffers are provided, which are symmetrically distributed on both sides of the slide plate.

[0014] Furthermore: an upwardly extending pressure plate is arranged on the slide board at a position corresponding to the driving arm, and the pressure plate is connected to the driving arm to push the slide board to move.

[0015] Furthermore: the pressure plate is also extended backward to be provided with a guide plate, and correspondingly, a limiting groove is provided in the bottom cover, and the guide plate slides in the limiting groove.

[0016] Furthermore: a reset plate is extended upwardly from the slide plate, and correspondingly, a reset arm is provided on the upper connecting rod. When the hinge is opened, the reset arm pushes the slide plate to reset through the reset plate.

[0017] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0018] 2. The present invention sets the buffer inside the bottom cover of the hinge cup instead of the traditional hinge arm, thus avoiding the problem of the hinge arm being too large due to the buffer occupying space. This design significantly reduces the external dimensions of the hinge, making the overall structure more compact, meeting the high requirements of modern furniture design for space utilization and exquisite appearance, and improving the aesthetics of the product.

[0019] 3. The bottom cover covers the bottom of the hinge cup through the downwardly concave accommodating cavity at the top, and is inserted into the buckle holes of the hinge cup using the elastic buckles on both sides to achieve fast and stable installation, and assembly can be completed without complicated tools.

[0020] 4. The buffer is installed in the mounting hole in the bottom cover. The fixing method is simple and connected to it through the connecting arm on the slide, which is easy to disassemble and replace. When the buffer needs to be maintained or replaced, only the bottom cover needs to be operated, avoiding the tedious process of disassembling the entire hinge, significantly reducing the difficulty and cost of maintenance.

[0021] 5. The present invention is connected to the slide plate through the driving arm on the upper connecting rod. When the hinge is closed, the driving arm pushes the slide plate to compress the buffer, generating a gentle damping effect, thereby ensuring that the door leaf closes smoothly without impact.

[0022] 6. According to actual needs, the buffer can be flexibly set on one side of the slide, or set to two and symmetrically distributed on both sides of the slide, so as to meet the damping requirements of different door leaf weights and closing speeds. This diversified design enhances the applicability of the hinge and can adapt to a variety of usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is further described in detail below with reference to the accompanying drawings. The present invention relates to a lower buffer hardware hinge, the core of which is to place a buffer mechanism in a bottom cover 6 at the bottom of a hinge cup 1, and through the linkage between a driving arm 31 on an upper connecting rod 3 and a slide plate 7, the buffer 8 is compressed during the closing process to generate a damping force, thereby achieving a soft closing; and during the opening process, the slide plate 7 is pushed to reset by a reset arm 32 and a reset plate 74, ensuring that the buffer 8 returns to its initial state.

[0029] When the door leaf is closed, the upper connecting rod 3 and the lower connecting rod 4 between the hinge cup 1 and the hinge arm 2 swing relative to the hinge cup 1 and the hinge arm 2, pushing the hinge to complete the closing action.

[0030] The driving arm 31 on the upper connecting rod 3 moves downward and inward, passes through the open slot 5 hollowed out at the bottom of the hinge cup 1, enters the bottom cover 6, and contacts the pressing plate 72 on the slide plate 7. When the hinge is closed to a set angle, the driving arm 31 pushes the pressing plate 72, causing the slide plate 7 to slide linearly along the guide slot 62 at the bottom of the inner cavity 61 of the bottom cover 6. The movement of the slide plate 7 is further constrained by the guide plate 73 and the limit slot 65 in the bottom cover 6 to ensure a stable trajectory.

[0031] The slide plate 7 is connected to the buffer 8 installed in the mounting hole 63 in the bottom cover 6 through the connecting arm 71 thereon. As the slide plate 7 slides, the buffer 8 is compressed, generating a damping force, slowing down the closing speed of the hinge, and finally realizing the soft closing of the door leaf.

[0032] The opening groove 5 runs through the bottom of the hinge cup 1, providing a passage for the driving arm 31 to enter the bottom cover 6. This design moves the buffer mechanism down to the bottom of the hinge cup, avoids the increase of the hinge arm volume, and maintains the compactness and aesthetics of the hinge.

[0033] It should be noted that the bottom cover 6 covers the bottom of the hinge cup 1 through the accommodating cavity 61, and is fixed by the elastic buckle 64 into the buckle hole 11 of the hinge cup 1, which is easy and stable to install. The slide plate 7 and the buffer 8 are accommodated inside, and the modular design is convenient for maintenance and replacement.

[0034] The slide plate 7 converts the rotational motion of the driving arm 31 into the linear compression of the buffer 8, the pressing plate 72 ensures a reliable connection with the driving arm, and the connecting arm 71 accurately transmits the motion to the buffer. Its sliding design ensures the stability of the damping process and improves the reliability of use.

[0035] Among them, the buffer 8 can be a self-resetting compression damping type hydraulic damping cylinder set on one side, or set symmetrically on both sides, providing different damping forces to adapt to different door weight environments.

[0036] When the door leaf is opened, the upper connecting rod 3 and the lower connecting rod 4 swing in opposite directions, the driving arm 31 leaves the pressing plate 72, and the pressure on the slide plate 7 is reduced. The reset arm 32 on the upper connecting rod 3 contacts the reset plate 74 on the slide plate 7. As the hinge continues to open, the reset arm 32 pushes the reset plate 74, so that the slide plate 7 slides along the guide groove 62 and returns to the initial position.

[0037] After the slide plate 7 is reset, the buffer 8 is decompressed and restored to its original state under the self-reset mechanism, ready for the next closing.

[0038] The reset arm 32 and the reset plate 74 constitute an automatic reset mechanism, which ensures that the slide plate 7 and the buffer 8 are restored to their initial state when opened, so as to prepare for the buffering of the next closing.

[0039] Therefore, when the hinge is closed, the driving arm 31 of the upper connecting rod 3 pushes the slide plate 7 through the opening slot 5, compressing the buffer 8 in the bottom cover 6, generating a damping force to slow down the closing speed. When the hinge is opened, the reset arm 32 pushes the reset plate 74 to reset the slide plate 7 and the buffer 8 to prepare for the next buffering.

[0040] Compared with the conventional technology, the buffer 8 of the present invention is arranged in the bottom cover 6 at the bottom of the hinge cup 1, rather than in the conventional hinge arm 2, thus avoiding the problem of the hinge arm being too large due to the space occupied by the buffer. This design significantly reduces the external dimensions of the hinge, making the overall structure more compact, meeting the high requirements of modern home design for space utilization and exquisite appearance, and improving the aesthetics of the product, so it can be widely promoted and used.

[0041] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
