Embodiment

Below cooperate preferred embodiment graphic and of the present utility model, further setting forth the utility model is to reach the technological means that predetermined model utility purpose is taked.

See also Figure 1 and Figure 2, Lever type pivot device 1 of the present utility model includes one, and fixedly bolster 10, an axostylus axostyle 20, a gasket assembly 30, rotate bolster 40, a brake sleeve 50 and a driven bolster 60.

Aforesaid axostylus axostyle 20 runs through fixedly bolster 10.

Aforesaid gasket assembly 30 is sheathed on the axostylus axostyle 20 and provides axostylus axostyle 20 friction stagnation power and location or function such as spacing.Described gasket assembly 30 comprises concavo-convex wheel assembly or plural friction pads and at least one elastic component (as shell fragment or spring), and this gasket assembly 30 is known techniques, does not add at this and gives unnecessary details.

Aforesaid rotation bolster 40 is sheathed and be fixed on the axostylus axostyle 20 and with axostylus axostyle 20 and rotate synchronously.

Aforesaid brake sleeve 50 is sheathed and be fixed on the axostylus axostyle 20 and with axostylus axostyle 20 and rotate synchronously, and brake sleeve 50 outer periphery are radially extended and are formed with a braking protuberance 51.

See also Fig. 1 to shown in Figure 3, aforesaid driven bolster 60 is adjacent to brake sleeve 50, driven bolster 60 has a socket end 61 and a free end 62, driven bolster 60 radially is hubbed on the bearing 601, the pivot 63 of driven bolster 60 does not overlap with the axle center 21 of axostylus axostyle 20, and the socket end 61 of driven bolster 60 is corresponding with the braking protuberance 51 of brake sleeve 50, in preferred embodiment, be formed with an inclined-plane 64 on the socket end 61, stride on the free end 62 to establish and be fixed with a cross bar 65.

When brake sleeve 50 is subjected to axostylus axostyle 20 driven rotary, make the inclined-plane 64 on the socket end 61 of braking protuberance 51 ejections or the driven bolster 60 of not ejection according to the angle of brake sleeve 50 rotation, when braking protuberance 51 not during ejection inclined-plane 64, driven bolster 60 is kept level, when braking protuberance 51 ejection inclined-planes 64, driven bolster 60 begins to pivot, and this moment, socket end 61 was stressed and be pressed down, free end 62 be upturned.

See also shown in Figure 4ly, portable electronic devices of the present utility model includes a base 70, a follower plate 80, a loam cake 90 and two aforesaid Lever type pivot devices 1.

Aforesaid base 70 has a front side 71 and a rear side 72, be provided with two relative pin joint seats 73 near rear side 72 places on the base 70, aforesaid follower plate 80 can be provided with a signal output unit or a signal input device, horn assembly for example, the auxiliary function key, or even this follower plate be a screen etc. (figure does not show), follower plate 80 is hubbed between two pin joint seats 73, be provided with a returning spring 81 between the ora terminalis of follower plate 80 and the base 70, two Lever type pivot devices 1 are located at respectively between loam cake 90 and the base 70 and are located near both sides, fixedly bolster 10 and bearing 601 bases 70 interfix, rotation bolster 40 interfixes with loam cake 90, the free end 62 ejection follower plates 80 of driven bolster 60, in preferred embodiment, driven bolster 60 utilizes cross bar 65 ejections in the bottom side of follower plate 80.

When loam cake 90 pivoted with respect to base 70, loam cake 90 driven rotary bolsters 40, axostylus axostyle 20 and brake sleeve 50 were with respect to fixedly

bolster

10 and 60 rotations of driven bolster.

See also Fig. 5 and shown in Figure 6, when loam cake 90 is relative opening state with base 70, the socket end 61 of the driven bolster 60 of braking protuberance 51 ejections of brake sleeve 50 and make that driven bolster 60 pivots and free end 62 moves upward, then driven bolster 60 utilizes cross bar 65 ejection follower plates 80, make follower plate 80 stressed and pivot, then the top side of follower plate 80 turns to forward, looks or utilize the device of being located on the follower plate 80 so that the user sees.

Please cooperate and consult Fig. 7 and shown in Figure 8, when loam cake 90 is relative closed state with base 70, the braking protuberance 51 of brake sleeve 50 breaks away from the socket end 61 of driven bolster 60, this moment, driven bolster 60 returned back to the two ends state of equilibrium because of losing external force according to lever principle, so the cross bar 65 of driven bolster 60 no longer ejection follower plate 80 upwards pivots, then follower plate 80 is subjected to the gravity of itself and the elastic force effect desire of returning spring 81 to reply the home position because of losing ejection strength, therefore, in closing stroke, follower plate 80 returns back to the home position along with the pivot of driven bolster 60.

See also Fig. 9 and shown in Figure 10, in another embodiment, pin joint seat 73 is located on the base 70 near 71 places, front side, to cooperate larger area follower plate 80A to use, at this moment, follower plate 80A can be provided with a signal output unit or a signal input device, for example keyboard group, so when the stressed and end perk of follower plate 80A, the keyboard group of inclination meets ergonomics and the user that is more convenient for knocks.

The above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, have in the technical field under any and know the knowledgeable usually, in the scope that does not break away from technical solutions of the utility model, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
