When the connecting arm 2 is hinged and opened relative to the bracket 1 and an included angle a between the first, second and third shaft parts is less than 180 degrees, the opening and closing acting piece 14 of the opening and closing assembly elastically moves on the bracket 1 and exerts an opening acting force on the connecting arm 2 through the opening and closing transmission piece 16 during the elastic movement.
When the connecting arm 2 is hinged and closed relative to the bracket 1 and the included angle a between the first, second and third shaft portions is greater than 180 degrees, the opening and closing acting piece 14 of the opening and closing assembly elastically moves on the bracket 1 and exerts a closing acting force on the connecting arm 2 through the opening and closing transmission piece 16 during the elastic movement.
The working principle is as follows:
as shown in fig. 6-10, the pressing member 3 is pressed to slide toward the bracket 1 and drive the intermediate member 5 to rotate or swing on the bracket 1, the intermediate member 5 drives the locking and unlocking member 4 to slide on the bracket 1 against the elastic force of the locking and unlocking elastic member 6 during rotation or swing, at this time, the locking and unlocking part 7 and the locking and unlocking matching part 9 are unlocked mutually, the pushing and pushing acting member 10 slides linearly (to the right) on the bracket 1 through the elasticity of the pushing and pushing elastic member 11 and drives the connecting arm 2 to hinge and open automatically; 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 acting element 10 slides to the right on the bracket 1 during the unlocking slide, the opening/closing acting element 14 slides linearly (to the left) in the opposite direction to the pushing acting element 10 due to the steering action of the connecting arm 2 and the opening/closing transmission element 16, and the opening/closing elastic element 15 stores energy in a compressed manner.
When the connecting arm 2 continues to be 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 member 14 realizes a 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 an opening acting force to the connecting arm 2 through the opening and closing transmission member 16, at this time, the pushing and resetting member 17 interacts with the opening and closing guide part 25, and the opening and resetting member 18 is driven to move on the opening and closing acting member 14 against the elastic force of the opening and closing resetting elastic member 20 and to mutually retreat with the pushing and resetting member 17; when the opening/closing operation member 14 continues to elastically move, the opening/closing guide portion 25 and the pushing and returning member 17 are separated from each other, and the opening/closing returning member 18 is returned to the initial position by the opening/closing returning elastic member 20 when the opening/closing guide portion 25 and the pushing and returning member 17 are separated from each other. The connecting arm 2 is then completely automatically hinged open by elastic sliding of the push acting element 10 and positioned on the stand 1.
When the connecting arm 2 is in the open state, a gap is formed between the pushing actuator 13 and the pushing action part 12.
As shown in fig. 11-15, a closing force is applied to the connecting arm 2, the connecting arm 2 is hinged and closed on the bracket 1, the opening and closing action member 14 is driven by the opening and closing transmission member 16 to move on the bracket 1 (to the left) against the elastic force of the opening and closing elastic member 15, and the opening and closing elastic member 15 compresses and stores 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 performs a steering action, the opening and closing acting member 14 elastically moves on the bracket 1 (rightward) through the opening and closing elastic member 15, and applies a closing acting force to the connecting arm 2 through the opening and closing transmission member 16. The connecting arm 2 is fully automatically hinged closed by elastic sliding of the pushing action 10 and is positioned on the stand 1.
In order to enable the connecting arm 2 to realize the damping hinge opening effect, 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 member 14 acts on the opening damper 29 when the connecting arm 2 is hinged open to a certain position with respect to the bracket 1, and the opening damper 29 is compressed and generates an opening damping force to realize the automatic damping hinge opening of the connecting arm 2 with respect to the bracket 1.
In order to enable the connecting arm 2 to realize a damping hinge closing effect, a closing damper 30 is further arranged on the support 1 or the pushing acting element 10 of the pushing assembly, and the closing damper 30 is an automatic resetting damper or a non-automatic resetting damper and is positioned on the support 1 or the pushing acting element 10; the pushing transmission element 13 of the transmission assembly 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 a closing damping force to realize the automatic damping hinged closing of the connecting arm 2 relative to the bracket 1.
