Description

Technical Field

[0001] The invention relates to an integrated optimized damping structure of a furniture hinge. Background Art

[0002] Chinese patent document number CN103953239B disclosed on July 6, 2016 a fixed base for furniture hinges, including an articulated arm, a connecting arm, a fixed base connected to a wall panel, and a movable cup holder connected to a door panel; the articulated arm is arranged on the fixed base through the connecting arm, and is connected to the movable cup holder through a hinge assembly, the connecting arm is arranged on the articulated arm, and is provided with a locking device, and is detachably connected to the fixed base through the locking device; the fixed base is in a straight line shape, and is provided with at least two fixing parts at the front and rear positions, and is fixed to the wall panel through the fixing parts; an adjusting component is provided at the rear of the fixed base, and the relative position between the wall panel and the door panel is adjusted by the adjusting component; the adjusting component is located behind the articulated arm and / or the connecting arm when the hinge is installed. It is said that the furniture hinge has the characteristics of simple and reasonable structure, reliable performance, flexible adjustment, low manufacturing cost, easy production, easy implementation, small space occupation, compact connection of components, exquisite appearance and high safety, and strong practicality; however, the damper of this structure is arranged in the connecting arm, and the connecting arm is arranged in the articulated arm, which makes the whole structure of the hinge more complicated, the production cost is high, and it is not convenient to manufacture and assemble. At the same time, the overall length is large, and it will take up more space when assembled in the furniture cabinet, affecting the storage space of the furniture cabinet. Moreover, the damper can only use the automatic reset damper, which has great limitations in use. When in use, due to production and assembly problems, the automatic reset damper is easy to get stuck, and it is impossible to truly achieve automatic damping and reset. Therefore, it is necessary to make further improvements. Summary of the invention

[0003] The purpose of the present invention is to provide an integrated optimized damping structure for furniture hinges with simple and reasonable structure, reliable performance, high flexibility of use, low manufacturing cost, long service life, easy production, easy implementation, exquisite appearance and high safety, so as to overcome the shortcomings of the prior art.

[0004] An integrated optimized damping structure of a furniture hinge designed for this purpose comprises a hinge cup (2) and a connecting arm (3) which are elastically hinged to each other for opening and closing through a hinge arm assembly and a hinge arm elastic member (1), and is characterized in that: the hinge arm assembly comprises at least an inner hinge arm (4), the inner hinge arm (4) being hinged to the hinge cup (2) and the connecting arm (3) respectively, a positioning member (5) being arranged on the inner hinge arm (4), the positioning member (5) being positioned on the inner hinge arm (4), and having an extension (6) arranged thereon, and acting on the hinge arm elastic member (1) or the hinge arm assembly through the extension (6) at least when subjected to force; a damper is arranged between the connecting arm (3) and the positioning member (5); the inner hinge arm (4) acts and drives the damper to reset and slide and / or compress and slide between the connecting arm (3) and the positioning member (5) when the hinge cup (2) is elastically hinged to open and close relative to the connecting arm (3), so as to realize automatic reset of the damper and / or damping closure of the furniture hinge.

[0005] The present invention has the following advantages compared with the prior art through the improvement of the above structure:

[0006] 1. A positioning piece is rotatably or swungly arranged on the inner hinge arm, and a slide groove is formed between the support portion of the positioning piece and the U-shape of the connecting arm. The damper is supported on the support portion and resets and / or compresses and slides on the slide groove through the action of the inner hinge arm, that is, the damper can be directly built into the connecting arm, thereby reducing the space occupied by the damper on the furniture hinge, reducing the overall volume of the furniture hinge, and reducing the space occupied by the furniture hinge when assembled on the furniture cabinet, so as to increase the storage space of the furniture cabinet. At the same time, it also reduces the disadvantage of the prior art that an intermediate piece must be used to assemble the damper, so as to reduce the production cost of the furniture hinge, and also simplifies the assembly steps and processes of the furniture hinge, which greatly meets the production and assembly requirements of the manufacturer.

[0007] 2. A single acting part is arranged on the inner hinge arm, and a groove part composed of a compression acting fitting part and a reset acting fitting part is arranged on the cylinder body of the damper. The acting part of the inner hinge arm will extend into the groove part during assembly, and at the same time, when the hinge cup is hinged and opened and closed relative to the connecting arm, the acting part will act on the compression acting fitting part and the reset acting fitting part respectively, so that the damper can be automatically reset and the damping closure of the furniture hinge can be realized. Since there is only one acting part, the production cost can be effectively reduced. At the same time, the acting part will extend into the groove part during assembly, so the assembly stability of the inner hinge arm and the cylinder body can be improved, and the problem that the acting part cannot interact normally with the compression acting fitting part and the reset acting fitting part can be avoided. At the same time, since the acting part interacts with the compression acting fitting part and the reset acting fitting part respectively, one acting part can realize the automatic reset of the damper and the damping closure of the furniture hinge, which effectively simplifies the structure of the furniture hinge and avoids the problem that the damper cannot be automatically reset or generate damping force due to non-standard production dimensions or inaccurate assembly positions, thereby further reducing production costs and simplifying assembly steps and processes.

[0008] 3. The extended part of the positioning piece interacts directly with the piston rod of the damper or forms a certain gap, which can improve the connection stability between the two when the furniture is opened and closed. At the same time, the extended part will be positioned on the hinge arm elastic part when subjected to force, and is fastened between the inner hinge arm and the hinge arm elastic part or on the hinge arm elastic part by at least one snap-fit ​​position. Therefore, the positioning piece is quite firm after assembly and will not come off during operation, thereby further improving the assembly stability of the damper.

[0009] 4. Since the damper can be automatically reset through the inner hinge arm, the furniture hinge can use an automatic reset damper or a non-automatic reset damper, thereby increasing the use range of the hinge product. At the same time, if a non-automatic reset damper is selected, there is no need to use a reset elastic part in the cylinder body, which can further reduce production costs, simplify assembly steps and processes, and reduce the length of the damper, making the overall volume of the furniture hinge lighter.

[0010] 5. A zigzag section is provided between the action part and the groove part, which means that the action part can convert force through the zigzag section when interacting with the compression action matching part and the reset action matching part respectively. It not only reduces the friction loss when the cylinder body and the inner hinge arm interact with each other, thereby extending the service life of the furniture hinge, but also the zigzag section can realize the uniform acceleration, uniform deceleration, or uniform speed hinged opening and closing of the furniture hinge, and also has a certain guiding effect, thereby improving the rationality of the connection between the components, the stability during operation and the user experience.

[0011] In general, it has the characteristics of simple and reasonable structure, reliable performance, high flexibility in use, low manufacturing cost, long service life, easy production, easy implementation, exquisite appearance and high safety, and strong practicality.
