Embodiment
At first please join Fig. 2, the utility model is provided with a fixed end link 10 and a movable end link 20, articulates with a pivot device 30 between the two, and makes pivot device 30 become the on-off action axle center of electronic equipment movable end.Said fixing end connection 10 is in order to the system end (figure does not show) of winding such as aforementioned notebook computer; 20 of movable end links (are LCD screen in order to winding at the loam cake that contains touch panel like aforementioned notebook computer; Figure does not show), form a required electronic equipment jointly.Simultaneously, said fixing end connection 10 and movable end link 20 are respectively equipped with phase conduplication side 11,21 and contain centrally-pivoted axle to constitute the pivot device 30 of vibration center line for winding one.
Please consult Fig. 2-Fig. 5 simultaneously; In the diagram preferred embodiment; Said fixing end connection 10 is provided with a bolster 40; This bolster 40 contains a flanging portion 41 relative with the flanging of fixed end link 10 11 equally, and described flanging and flanging portion 11,41 are provided with the relative expansion of the diameter width of the centrally-pivoted axle that cooperates pivot device 30 and extend slotted hole 12,42, and can be in these phase conduplication sides and flanging portion 11, be situated between between 41 adorn one contain center hole 51 cam 50.
In illustrated embodiment; The centrally-pivoted axle 31 that is connected to the above-mentioned pivot device 30 of movable end link 20 passes the center hole 51 of the slotted hole 12 of fixed end link 10, cam 50 and the slotted hole 42 of bolster 40 in regular turn; After other end wears in order to the resilient member 32 and the relevant pad 33 of cooperation that produce axially support power, all component compositions are located then with locking member 34.In illustrated embodiment, resilient member 32 is a ware type spring, 34 relative nuts for cooperation pivot 31 preset threaded sections of locking member; Fixed end link 10 and bolster 40 then can combine with riveted spare 35 via preset overlapping hole.
The pivot 31 winding interlocks of above-mentioned cam 50 and above-mentioned pivot device 30, in illustrated embodiment, pivot 31 axle bodies of pivot device 30 contain the relative up and down face that scabbles, and the center hole 51 of cam 50 is made as the section configuration identical with it, and both can consistently be rotated synchronously.
Please join Fig. 3 and Fig. 5, in the diagram preferred embodiment, above-mentioned cam 50 is provided with first a camber line portion 52 coaxial with the vibration center line C of centrally-pivoted axle 31, form one apart from vibration center line C lack apart from d
1(attaching ginseng Fig. 6 A); And extend the two relative tangent line portions 53,54 that depart from vibration center line C outward by this first camber line portion 52; Again further in said two relative tangent line portions 53, constitute one second camber line portion 55 between 54, form one apart from vibration center line C long apart from d
2(attaching ginseng Fig. 6 A).
Cooperate above-mentioned cam 50 structures, between the flanging 11 of said fixed end link 10 and bolster 40 and flanging portion 41, be provided with the restriction pressure guiding device of cam.In illustrated embodiment; Said restriction pressure guiding device is included in to be respectively equipped with on flanging 11 and 41 apparent surfaces' of flanging portion the relative position and cooperates the upper and lower system lead sheeting 13,14 and 43,44 (ginseng Fig. 3 and Fig. 3 A) of 52 to second camber line portions 55 of cam 50 first camber line portions apart from length, and the guiding up and down when forming cam 50 rotations urges device.
The start situation that below will cooperate this embodiment of Fig. 6 A to Fig. 6 D explanation the utility model; Fig. 6 A show events end connection 20 is not opened (electronic equipment closed condition) as yet; This moment, the first camber line portion 52 of cam 50 was pressed against limit lead sheeting 14 and 44 (this figure only shows wherein lead sheeting 14 once), and the distance of the vibration center line C and the first camber line portion 52 is d
155 in the second camber line portion of cam 50 is pressed against limit lead sheeting 13 and 43 (this figure only shows wherein lead sheeting 13 on), and the distance of the vibration center line C and the second camber line portion 55 is d
2Under this closed condition, whole pivot 31 bears in enlarging together with associated components and extends slotted hole 12,42 (this figure only shows a wherein slotted hole 12) near interior lower edge position.
When movable end link 20 is opened to the position, 90 ° of angles shown in 6B figure; Because cam 50 and pivot 31 winding interlocks; Whole cam 50 also rotates 90 ° along with pivot 31, makes the first camber line portion 52 of cam 50 be pressed against limit lead sheeting 13 and 43 (this figure only shows wherein lead sheeting 13 on) gradually; 55 in the second camber line portion of cam 50 turns to gradually and is pressed against limit lead sheeting 14 and 44 (this figure only shows wherein lead sheeting 14 once).Whole pivot 31 receives to compel upwards to promote to bear in enlarging together with associated components and extends slotted hole 12,42 (this figure only shows a wherein slotted hole 12) near interior upper limb position.
When movable end link 20 continues to be opened to outward hexagonal angle even the position, 170 ° of angles shown in Fig. 6 D shown in Fig. 6 C; Because whole pivot 31 receives to compel upwards to promote together with associated components; As shown in Figure 7; Movable end link 20 (promptly illustrating the LCD screen 200 of institute's winding interlock) will make progress the lifting generation like illustrated a shift length simultaneously with the pivot 31 of fixed end link 10 (promptly illustrating the system end main frame 100 of institute's winding interlock); LCD screen 200 can not abut to the face of bearing in the rotation displacement process of opening, thereby can significantly increase the display screen open angle of movable end link 20 and institute's winding thereof.Relative, the system end main frame thickness of 10 winding interlocks of fixed end link also can the demand of looking dwindle.
In Fig. 8 and another possible embodiments of the utility model shown in Figure 9; The flanging 11 of fixed end link 10 and bolster 40 and the cam between the flanging portion 41 restriction pressure guiding device comprises the limit lead sheeting 130 of being located at flanging 11 and flanging portion 41 relative positions (this figure only shows wherein lead sheeting 13 on); And one be located at that 140 of the axostylus axostyles of 41 in flanging 11 and flanging portion are common to be constituted, and this embodiment will make the action of whole device more reliable and stable.
The utility model thereby form a kind of electronic equipment display screen lifting mechanism; Promote via interlock pivot in the movable end link opening process; Solve suffered restriction in this class of electronic devices loam cake opening process; Can effectively increase the opening angle of movable end link (and the LCD screen that is connected), simultaneously, system host thickness is slimming more also.
Above embodiment only uses to conveniently illustrating the utility model, be not in a limitative way, for have the knack of this skill personage according to this embodiment various simple and easy distortion and the modification that can do, all must include in following claim.
