Embodiment

The utility model novelty and other characteristics will be tending towards clear in cooperating the following drawings preferred embodiment to describe in detail.

At first please refer to the drawing 1, in the diagram possible embodiments, the utility model is provided with one for the lower supporter 10 that is connected to the electronic equipment body, and a travel(l)ing rest 20 in order to be connected to the electronic equipment loam cake, connect with a pivot device 30 between described lower supporter 10 and the travel(l)ing rest 20, travel(l)ing rest 20 can be raised or closure as the action axle center take pivot device together with the electronic equipment loam cake.

Please consult simultaneously Fig. 2 and Fig. 3, above-mentioned lower supporter 10 is in pivot 31 and the sector unit 32 in order to locate stroke of end winding one in order to consist of pivot device 30; 20 of above-mentioned travel(l)ing rests are provided with a center hole 21, and described pivot 31 is passed by these center hole 21 1 sides, and other side sequentially sheathed friction plate 33, relative recessedly take turns 35 and cam 36, pad 34, elastic device 37 and fixing device 38.

Above-mentioned pivot 31 axle bodies are default to scabble face, and 36 on above-mentioned cam contains relative Section Central hole 360 makes both can engage interlock; The above-mentioned recessed 35 default cutting graftage parts 350 of taking turns are for plugging together interlock in the other relative jack 22 of travel(l)ing rest 20 center holes 21.

As shown in Figure 3, above-mentioned recessed take turns 35 and cam 36 be provided with relative interference surface, wherein, cam 36 is provided with two relatively shallow lug bosses 361,362 along its central hole 360 inner rings, described shallow lug boss 361,362 is respectively equipped with inclined plane part 363,364 in two ends; Then be provided with two relative ridges 365,366 in central hole 360 outer rings near the periphery.Above-mentionedly recessedly take turns 35 and be respectively equipped with two reentrant part 351,352 with respect to shallow boss shapes with above-mentioned cam 36 shallow lug bosses 361,362 relative positions, the female section 351,352 is provided with the oblique surface 353,354 with respect to inclined plane part 363,364 protuberance setting heights, then be provided with relative slideway 355,356 along described oblique surface 353,354 tops in same radial position, simultaneously, then be provided with relative outer ring pressing block 357,358 in outer radial position more.

Such as Fig. 4 and shown in Figure 5, when electronic equipment loam cake travel(l)ing rest 20 shown in Figure 1 is opened as the action axle center take pivot device 30, the recessed of pivot device 30 takes turns 35 according to counterrotating shown in the arrow, make cam 36 shallow lug bosses 361,362 first set strength with one and break away from recessed 35 the reentrant part 351,352 of taking turns, cam 36 shallow lug bosses 361,362 are moved along slideway 355,356, and it is one normally to raise stroke.When cam 36 shallow lug bosses 361,362 continue along the arrival set angle of direction rotation shown in the arrow (between such as 110 ° to 120 °), such as Figure 6 and Figure 7, default cam 36 ridges 365,366 will be connected across the recessed 35 outer ring pressing blocks 357,358 of taking turns, and form the support torsion strength of further strengthening.Set angle between above-mentioned 110 ° to 120 ° only with for conveniently illustrating, is limited, and it is relevant that the angle that sets and loam cake are raised the position, can be set according to user's demand.

As shown in Figure 8, when above-mentioned cam 36 shallow lug bosses 361,362 break away from (unlatching) or enter (closure) recessed reentrant part 351 of 35 of taking turns, 352 o'clock, default relative inclined plane part 363 at its two ends, 364 and oblique surface 353,354 help to open or auto-closing, it is first paragraph torsion T1, cam 36 shallow lug bosses 361,362 along slideway 355,356 move and are second segment torsion T2, at cam 36 ridges 365,366 will be connected across the recessed 35 outer ring pressing blocks 357 of taking turns, 358 o'clock, be the 3rd section torsion T3, can find out that it has higher torque value, namely higher supporting structure intensity.As for by the gradient S between three sections torsion T3 of second segment torsion T2 to the, then can be made as between 110 ° to 120 ° that make things convenient for open operation and touch-control electronic equipment loam cake.
