[0003] The purpose of the present invention is to provide an optimized damping opening and closing structure of a furniture hinge 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 optimized damping opening and closing structure of a furniture hinge designed for this purpose comprises a hinge cup and a connecting arm which are hinged to each other for opening and closing through a hinge arm assembly, and is characterized in that: the hinge arm assembly comprises at least an inner hinge arm, which is hinged to the hinge cup and the connecting arm respectively, and an acting part is extended therefrom; a damper is arranged on the connecting arm, and the damper comprises at least a cylinder body, and a groove is arranged on the cylinder body; when the hinge cup is hinged to open and close relative to the connecting arm, the inner hinge arm acts on the groove of the cylinder body through the acting part, and the cylinder body resets and slides and / or compresses and slides on the connecting arm through the interaction between the groove and the acting part, so as to realize automatic reset of the damper and / or damping closing of the furniture hinge.

[0005] One end of the inner hinge arm is hinged to the hinge cup, the middle part is hinged to the connecting arm, and the other end is extended with an action part, which extends into the groove of the cylinder body; wherein a bending section is arranged between the action part and the groove, and the two interact with each other through the bending section when the hinge cup is hinged to open and close relative to the connecting arm.

[0006] The action parts are provided with two, which are a compression action part and a reset action part respectively.

[0007] The inner hinge arm acts on the groove of the cylinder body through the compression action part when the hinge cup is hinged and closed relative to the connecting arm. The cylinder body is compressed and slides on the connecting arm through the interaction between the groove and the compression action part. The damper generates a damping force when the cylinder body is compressed and slides, so as to realize the damping closing of the furniture hinge.

[0008] The inner hinge arm acts on the groove of the cylinder body through the reset action part when the hinge cup is hinged and opened relative to the connecting arm. The cylinder body resets and slides on the connecting arm through the interaction between the groove and the reset action part. The damper automatically resets when the cylinder body resets and slides.

[0009] The cylinder body is provided with a compression matching part and a reset matching part; the groove is located between the compression matching part and the reset matching part.

[0010] When the hinge cup is hinged and closed relative to the connecting arm, the inner hinge arm acts on the compression matching part of the cylinder body through the compression acting part to achieve damping closing of the furniture hinge.

[0011] When the hinge cup is hinged and opened relative to the connecting arm, the inner hinge arm acts on the reset action matching part of the cylinder body through the reset action part to realize the automatic reset of the damper.

[0012] A high and low step is formed between the reset action part and the compression action part; the compression action matching part and the reset action matching part are arranged at different heights and form a certain front-to-back spacing between them, and the groove is located within the front-to-back spacing.

[0013] The hinge arm assembly also includes an outer hinge arm, one end of the outer hinge arm and the inner hinge arm are respectively hinged to the hinge cup, and the other end is respectively hinged to the connecting arm; wherein a connecting shaft is provided at the hinge of the outer hinge arm and the connecting arm, and a hinge arm elastic part is connected through the connecting shaft; the hinge cup is opened and closed on the connecting arm through the coordinated elastic hinge of the outer hinge arm, the inner hinge arm and the hinge arm elastic part.

[0014] The damper is an automatic reset damper and also includes a piston and a piston rod. The piston is arranged in a cylinder body. One end of the piston rod is positioned and acts on the connecting arm, or the connecting shaft, or the hinge arm elastic member, and the other end is connected to the piston and slides in the cylinder body through the expansion and contraction of the piston. The cylinder body is made of plastic and a reset elastic member is arranged inside it. One end of the reset elastic member elastically acts on the cylinder body, and the other end elastically acts on the piston. The cylinder body is automatically reset and positioned and slides on the connecting arm through the action of the reset elastic member and / or the connecting arm.

[0015] Alternatively, the damper is a non-automatic reset damper and also includes a piston and a piston rod. The piston is arranged in a cylinder body, one end of the piston rod is fixedly arranged on a connecting arm, or a connecting shaft, or a hinge arm elastic member, and the other end is cooperatively connected to the piston and slides in the cylinder body through the expansion and contraction of the piston. The cylinder body is made of plastic and slides on the connecting arm in an automatically reset positioning manner through the action of the connecting arm.

[0016] The connecting arm is U-shaped and a positioning portion is arranged inside the U-shape; the cylinder body is arranged inside the U-shape and a positioning matching portion is arranged on it, and is positioned and slid inside the U-shape of the connecting arm and / or on the positioning portion through the positioning matching portion.

[0017] The hinge arm elastic member is a torsion spring, and a connecting portion is arranged in the middle thereof; the connecting shaft is passed through the connecting portion, and the hinge arm elastic member is positioned at the hinge between the outer hinge arm and the connecting arm through the connecting shaft; at least two supporting legs are also arranged on the hinge arm elastic member, and the at least two supporting legs are respectively a first supporting leg and a second supporting leg, and the hinge arm elastic member elastically acts on the connecting arm through the first supporting leg, and the hinge arm elastic member elastically acts on the inner hinge arm through the second supporting leg.

[0018] The connecting arm is also provided with a fixed base, which is slidably or snap-on detachably arranged on the connecting arm, and an up and down adjustment member and / or a front and back adjustment member are arranged between the fixed base and the connecting arm. The up and down adjustment member and / or the front and back adjustment member are used to adjust the up and down and / or front and back relative position between the fixed base and the connecting arm.

[0019] The present invention has the following advantages compared with the prior art through the improvement of the above structure:

[0020] 1. The U-shaped position and the positioning part of the connecting arm are used to form a sliding space, and then the positioning matching part arranged on the cylinder body is used to position and slide on the sliding space, so that the damper can be directly arranged in the connecting arm, thereby reducing the space occupied by the damper in the furniture hinge, reducing the overall volume of the furniture hinge, reducing the space occupied by the furniture hinge when assembled in the furniture cabinet, so as to increase the storage space of the furniture cabinet, and at the same time reducing 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 simplify the assembly steps and processes of the furniture hinge, which greatly meets the production and assembly needs of the manufacturer.

[0021] 2. A compression acting part and a reset acting part are arranged on the inner hinge arm, and a groove part composed of a compression acting matching part and a reset acting matching part is arranged on the cylinder body of the damper. The compression acting part and the reset acting part of the inner hinge arm will extend into the groove part during assembly. At the same time, when the hinge cup is hinged to open and close relative to the connecting arm, the compression acting part and the reset acting part will act on the compression acting matching part and the reset acting matching part respectively, so that the damper can be automatically reset and the damping closing of the furniture hinge can be realized. Since the compression acting part and the reset acting part will extend into the groove part during assembly, the inner hinge arm can be improved. The assembly stability of the hinge arm and the cylinder body avoids the problem that the compression action part and the reset action part cannot interact normally with the compression action matching part and the reset action matching part respectively. At the same time, since the compression action part and the reset action part interact with the compression action matching part and the reset action matching part respectively, the automatic reset of the damper and the damping closure of the furniture hinge can be guaranteed, which effectively avoids the problem that the damper cannot automatically reset or generate damping force due to non-standard production dimensions or inaccurate assembly position, thereby further reducing production costs and simplifying assembly steps and processes.

[0022] 3. 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.

[0023] 4. A zigzag section is provided between the action part and the groove part, which means that when the compression action part and the reset action part interact with the compression action matching part and the reset action matching part respectively, the force can be converted through the zigzag section. This 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.

[0024] 5. A sliding or snap-on detachable fixed base is provided on the connecting arm. The user can quickly and conveniently disassemble and assemble the connecting arm and the fixed base during use. An up and down adjustment member and / or a front and back adjustment member are also provided between the fixed base and the connecting arm. The user can adjust the up and down and / or front and back relative position between the fixed base and the connecting arm through the up and down adjustment member and / or the front and back adjustment member according to actual use needs, thereby improving the overall aesthetics of the furniture hinge and making the use of the furniture hinge more convenient.

[0025] 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.
