as shown in fig. 15-19, the furniture door 50 is pressed, so that the furniture door 50 drives the pressing member 3 to slide towards the direction of the bracket 1 and drives the intermediate member 5 to rotate or swing on the bracket 1, the intermediate member 5 drives the locking and separating member 4 to slide on the bracket 1 against the elastic force of the locking and separating elastic member 6 during rotation or swing, at this time, the locking and separating part 7 and the locking and separating matching part 9 are unlocked mutually, the pushing acting member 10 slides on the bracket 1 linearly (rightwards) through the elastic force of the pushing elastic member 11, and the furniture door 50 and the connecting arm 2 are driven to be automatically hinged and opened; wherein, the pushing acting element 10 acts on the guide part 21 through the guide matching part 23 when the elastic linear sliding is carried out to a certain position, and drives the pushing reset element 17 to move on the pushing acting element 10 against the elastic force of the pushing reset elastic element 19.

The elastic force generated by the pushing elastic member 11 is larger than the elastic force generated by the opening/closing elastic member 15. Therefore, the pushing action member 10 slides rightward on the bracket 1 during the unlocking slide, the opening/closing action member 14 linearly slides in the opposite direction (leftward) with respect to the pushing action member 10 due to the steering action of the link arm 2 and the opening/closing transmission member 16, and the opening/closing elastic member 15 is compressed to store energy.

When the furniture door body 50 and the connecting arm 2 are continuously and automatically opened due to inertia, and an included angle a between the first, second and third shaft parts is smaller than 180 degrees, the opening and closing acting piece 14 realizes a steering action, the opening and closing acting piece 14 elastically moves on the bracket 1 (rightwards) through the opening and closing elastic piece 15, and applies an opening acting force to the furniture door body 50 and the connecting arm 2 through the opening and closing driving piece 16, at the moment, the pushing and resetting piece 17 interacts with the opening and closing guiding part 25, and the opening and closing resetting piece 18 is driven to overcome the elastic movement of the opening and closing resetting elastic piece 20, move on the opening and closing acting piece 14 and mutually avoid the pushing and resetting piece 17; when the opening/closing operation element 14 continues to elastically move, the opening/closing guide portion 25 and the pushing and returning element 17 are separated from each other, and the opening/closing returning element 18 is returned to the initial position by the opening/closing returning elastic element 20 when the opening/closing guide portion 25 is separated from the pushing and returning element 17. The furniture door 50 and the connecting arm 2 are completely automatically hinged and opened by the elastic sliding of the pushing action piece 10, and are positioned on the furniture cabinet 49 and the bracket 1.

When the furniture cabinet 49 is in an open state, a space is formed between the pushing transmission member 13 and the pushing action part 12.

As shown in fig. 20-24, a closing force is applied to the furniture cabinet 49, the furniture cabinet 49 and the connecting arm 2 are hinged and closed on the furniture cabinet 49 and the bracket 1, the opening and closing action piece 14 is driven by the opening and closing transmission piece 16 to move on the bracket 1 (leftwards) against the elastic force of the opening and closing elastic piece 15, and the opening and closing elastic piece 15 is compressed and stored with energy; when the opening and closing acting element 14 moves to a certain position, the reset matching part 24 acts on the reset part 22 and drives the pushing acting element 10 to reset and slide (leftwards) against the elastic force of the pushing elastic element 11, when the pushing acting element 10 resets and slides to a certain position, the pushing acting element 10 is locked with the locking and separating element 4 of the pressing assembly through the locking and separating matching part 9, at the moment, the guide matching part 23 is separated from the guide part 21, the reset matching part 24 is separated from the reset part 22, and the pushing and resetting element 17 resets to an initial position through the pushing and resetting elastic element 19.

When the included angle a between the first, second and third shaft portions is greater than 180 degrees, the opening and closing acting member 14 realizes the steering action, the opening and closing acting member 14 elastically moves on the bracket 1 (rightwards) through the opening and closing elastic member 15, and applies closing acting force to the furniture door body 50 and the connecting arm 2 through the opening and closing transmission member 16. The furniture door 50 and the connecting arm 2 are completely automatically hinged and closed by the elastic sliding of the sliding acting element 10 and are positioned on the furniture cabinet 49 and the bracket 1.

In order to enable a damped hinged opening and/or closing effect of the furniture door body 50 and the connecting arm 2.

An opening damper 29 is further arranged on the bracket 1 or the opening and closing acting piece 14 of the opening and closing assembly, and the opening damper 29 is an automatic reset damper or a non-automatic reset damper and is positioned on the bracket 1 or the opening and closing acting piece 14; the opening and closing acting piece 14 acts on the opening damper 29 when the connecting arm 2 is hinged and opened to a certain position relative to the bracket 1, the opening damper 29 compresses and generates opening damping force, and therefore automatic damping hinged opening of the furniture door body 50 and the connecting arm 2 relative to the furniture cabinet 49 and the bracket 1 is achieved.

A closing damper 30 is further arranged on the support 1 or the pushing acting piece 10 of the pushing assembly, and the closing damper 30 is an automatic reset damper or a non-automatic reset damper and is positioned on the support 1 or the pushing acting piece 10; the pushing transmission piece 13 of the transmission component acts on the closing damper 30 when the connecting arm 2 is hinged and closed to a certain position relative to the bracket 1, and the closing damper 30 compresses and generates closing damping force, so that the furniture door body 50 and the connecting arm 2 are automatically and damping hinged and closed relative to the furniture cabinet 49 and the bracket 1.
