Embodiment
See also Fig. 1-shown in Figure 4, they are other angle schematic representation of combination stereogram, assembly exploded view and the link of the utility model.The convertible pivot device of the twin shaft of the utility model comprises:
The axle sleeve 31 coating directions that the axle sleeve 21 of first coating member 2 coats the direction and second coating member 3 are identical, are all clockwise coating, or coat counterclockwise, and are as shown in Figure 2.
First axle 4 and second axle, 5, the first coating members 2 coat with its axle sleeve 21 and tighten first axle 4, and can relatively rotate generation friction torsion.Second coating member 3 coats with its axle sleeve 31 and tightens second axle 5, and can relatively rotate generation friction torsion.One end of first axle 4 is provided with fixing part 40, also is provided with fixing part 50 in order to an end of screen 6, the second axles 5 that are fixed to electronic equipment, and is in order to the base 7 that is fixed to electronic equipment, as shown in Figure 5.
The axostylus axostyle dual-side of first axle 4 is provided with two planes 41 of relative 180 degree, can form the locating locking function two angles with the plane 20 of first coating member 2, for example 0 degree and 180 degree.The axostylus axostyle dual-side of second axle 5 also is provided with two planes 51 of relative 180 degree, can form the locating locking function two angles with the plane 30 of second coating member 3.
After first axle 4 is arranged in first coating member 2, terminal and fasten with cramp 26, axially come off preventing.After second axle 5 was arranged in second coating member 3, end also fastened with cramp 36, to prevent axially to deviate from.
Utilize above-mentioned structure, see also Fig. 5-Fig. 7, for the utility model pivot device is installed in the application illustration of notebook computer or electronic equipments such as flat computer or e-book, Fig. 5-Fig. 7 is the schematic representation that 0 degree covers.When covering, 20 positions, plane that one of them plane 41 of first axle 4 is positioned at first coating member 2 form locating locking at 0 degree, and 30 positions, plane that one of them plane 51 of second axle 5 is positioned at second coating member 3 form locating locking, and are as shown in Figure 6.
During unlatching, as shown in Figure 6, first axle 4 that is fixed in screen 6 is rotated counterclockwise in first coating member 2; Torsion is lower; And second coating member 3 is higher with respect to the torsion of second axle, 5 rotations, so when 0～180 opens, can be rotated by first axle, 4 relative first coating members 2 earlier and open.At this moment, the plane 41 of first axle 4 is rotated away from the plane 20 of first coating member 2 and leaves locked position of coupler, and pivot device produces friction torsion by first axle 4 and first coating member 2.When being opened to 180 when spending; As shown in Figure 9; Block 42 blocks of first axle 4 are in the block 25 of first coating member 2, and can't rotate again, and 20 positions, plane that another plane 41 of first axle 4 goes to first coating member 2 form locking once again; As shown in Figure 8, can make things convenient for handwriting input or touch control operation this moment.
Turn to 270 when spending when continue opening; Like Figure 10-shown in Figure 11; First axle 4 drives the link 1 of first coating member 2 and fixing first coating member 2, rotarily opens around second axle 5, produces friction torsion and change by second coating member 3 with respect to 5 rotations of second axle; And the plane 30 of second coating member 3 is rotated away from the plane 51 of second axle 5, and is shown in figure 10.
Consulting Figure 12-shown in Figure 13 again, is the schematic representation that is flipped open and oppositely coincides to 360 degree.At this moment, another plane 51 that the plane 30 of second coating member 3 rotates to second axle 5 fits and locking once again, so, can make things convenient for the handheld touch operation.
When counter-rotating was closed, shown in figure 12, the torsion that produces between first coating member 2 and first axle 4 was higher; The torsion that produces between second coating member 3 and second axle 5 is lower, thus second coating member, 3 relative second axles 5 rotate earlier, the block 35 of second coating member 3 when anti-turnback block in the block 52 of second axle 5; And can't rotate again, as shown in Figure 9, therefore rotate with respect to first coating member 2 through first axle 4; And get back to 0 degree closed state, as shown in Figure 7.
Seeing also Figure 14-Figure 15, is another embodiment's of the utility model three-dimensional combination figure and assembly exploded view.The convertible pivot device of the twin shaft of the utility model comprises link 1, and its inside is provided with first receiving hole 11 and second receiving hole 12 side by side.First receiving hole 11 comprises circular cylinder hole 110 and is communicated with the microscler positioning hole 111 in tube hole 110, near first receiving hole, 11 places and be provided with fixed hole 17.Second receiving hole 12 is a circular axis hole, and end is provided with the non-circular fixed hole 19 of section.
The axostylus axostyle dual-side that axle sleeve 21 inside of this first coating member 2 are formed with a plane 20, the first axles 4 is provided with two planes 41 of relative 180 degree, can form the locating locking of two angles with the plane 20 of first coating member 2.
Utilize above-mentioned structure, when present embodiment was applied to electronic equipment, first axle 4 and second coating member 3 distinctly were fixed in screen and base.When screen rotarily opens; Shown in figure 16; First axle 4 that is fixed in screen 6 is rotated counterclockwise in first coating member 2, and torsion is lower, and second axle 5 is higher with respect to the torsion that second coating member 3 rotates; So when 0～180 degree is opened, can rotate by first axle, 4 relative first coating members 2 earlier and open.At this moment, the plane 41 of first axle 4 is rotated away from the plane 20 of first coating member 2 and leaves locked position of coupler, and pivot device is relatively rotated by first axle 4 and first coating member 2 and produces friction torsion.
When being opened to 180 when spending; Shown in figure 17, block 42 blocks of first axle 4 are in the block 25 of first coating member 2, and can't rotate again; And 20 positions, plane that another plane 41 of first axle 4 goes to first coating member 2 form locking once again, and can make things convenient for handwriting input or touch control operation this moment.
Turn to 270 when spending when continue opening; Shown in figure 18; Promptly change by second axle 5 and in second coating member 3, rotate generation friction torsion; The link 1 that first axle 4 drives first coating member 2 and fixing first coating member 2 rotates together, and the plane 51 of second axle 5 is rotated away from the plane 30 of second coating member 3, and leaves locked position of coupler.
Consult shown in Figure 19 again; Be the schematic representation that is flipped open and oppositely coincides to 360 degree; At this moment, block 52 blocks of second axle 5 are positioned the block 35 of second coating member 3, and another plane 51 that the plane 30 of second coating member 3 rotates to second axle 5 fits and locking once again; So, can make things convenient for the handheld touch operation.
When counter-rotating was closed, the friction torsion that produces between first coating member 2 and first axle 4 was higher, and the friction torsion that produces between second coating member 3 and second axle 5 is lower, so, rotate earlier with respect to second coating member 3 by second axle 5.The block 52 of second axle 5 block when anti-turnback and can't rotate in the block 35 of second coating member 3 again, and is shown in figure 17, therefore promptly changes by first axle 4 with respect to 2 rotations of first coating member, and gets back to 0 degree closed state, shown in figure 16.
