The working principle is as follows:
referring to fig. 12 to 14, when the furniture door 46 is in a closed state, the furniture door 46 is pressed to act on the pressing part 5, so that the acting element 3 rotates or swings on the bracket 1 against the elastic force of the pressing elastic element 4, the locking part 6 is separated from the locking matching part 10 when the pressing acting element 3 rotates or swings, at this time, the pushing acting element 8 elastically and linearly slides on the bracket 1 (rightward) through the pushing elastic element 9, acts on the pressing guide part 16 through the pushing guide part 14 when the elastic and linear sliding reaches a certain position, acts on the pushing guide part 16 through the pushing acting part 13 and drives the opening transmission piece 11 to linearly slide on the bracket 1 (rightward), and the opening transmission piece 11 drives the furniture door 46 and the connecting arm 2 to automatically hinge and open a certain position relative to the furniture cabinet 45 and the bracket 1 when the elastic and linear sliding; wherein, open driving medium 11 and reset driving medium 12 and articulate respectively in linking arm 2 both sides, therefore, furniture door body 46 and linking arm 2 are when automatic articulated opening, reset driving medium 12 can open driving medium 11 relatively and do the slip of opposite direction (namely reset driving medium 12 slides on support 1 left), and at this moment, reset portion 15 relies on each other or clearance fit with reset driving medium 12 when furniture door body 46 and linking arm 2 open a certain position.
When the furniture door 46 and the connecting arm 2 are hinged and opened relative to the furniture cabinet body 45 and the bracket 1 continuously (through the action of external force), the reset transmission piece 12 is driven to slide on the bracket 1 linearly (leftwards), the reset transmission piece 12 acts on the reset part 15 during linear sliding, and the reset transmission piece 8 is driven to overcome the elasticity of the pushing elastic piece 9 and slide on the bracket 1 in a reset way; when the pushing action piece 8 slides to a certain position again, the pushing guide part 14 is separated from the pressing guide part 16, the pressing action piece 3 rotates or swings on the bracket 1 again through the elastic force of the pressing elastic piece 4 and is locked with the locking matching part 10 through the locking part 6, at this time, the pushing action piece 8 is positioned on the bracket 1, the opening transmission piece 11 slides in the opposite direction relative to the resetting transmission piece 12 through the hinge of the connecting arm 2 (namely, the opening transmission piece 11 slides on the bracket 1 rightwards), and forms a distance with the pushing action part 13.
Referring to fig. 15 and 16, since the pushing acting element 8 is in the locked state and has no action relationship with the opening transmission element 11 and the return transmission element 12, the furniture door 46 and the connecting arm 2 can be freely hinged to open and close the furniture cabinet 45 and the bracket 1, and the opening transmission element 11 and the return transmission element 12 respectively slide on the bracket 1 in different directions when the furniture door 46 and the connecting arm 2 are hinged to open and close the furniture cabinet.
In order to make the driving between the connecting arm 2 and the reset transmission piece 12 more stable, an intermediate piece 18 is further arranged between the reset transmission piece 12 and the connecting arm 2, one end of the intermediate piece 18 is hinged with the reset transmission piece 12, and the other end of the intermediate piece 18 is hinged with the connecting arm 2; the reset transmission element 12 and the connecting arm 2 are in articulated driving connection with each other via an intermediate element 18.
Since the distance between the opening transmission element 11 and the pushing action element 8 and/or between the return transmission element 12 and the pushing action element 8 is formed during operation, in order to reduce the occurrence of collisions and noise of the above-mentioned components during the opening and closing of the connecting arm 2, a crash prevention element 19 is arranged between the opening transmission element 11 and the pushing action element 8 and/or between the return transmission element 12 and the pushing action element 8, and is connected in a crash-proof manner by the crash prevention element 19.
