To shown in Figure 9, described rotating shaft 30 comprises that one is installed in two first sleeves 31 and second sleeve 32 that is installed on described second body 20 on described first body 10 as Fig. 6.Described rotating shaft 30 also comprises a limiting tooth 33, a spring 34 and a positioning tooth 35.Described two first sleeves 31 are installed on first loading plate 121 of first body 10 end near described first time bonnet 124; Described second sleeve 32 is installed on second loading plate 221 of second body 20 end near described second time bonnet 224.End at described second sleeve 32 is provided with a protuberance 321.Described two first sleeves 31 comprise corresponding first axis hole 311 respectively.Described second sleeve 32 comprises that offers second axis hole 322 that runs through second sleeve 32 vertically, and the other end at protuberance 321 places is a Triaxial hole 325 relatively on second axis hole 322, and the aperture of described Triaxial hole 325 also is provided with a projection 323 greater than the aperture of described second axis hole 322 in described Triaxial hole 325.Described limiting tooth 33 is a torus, is provided with the spacing denticle 331 that spacing equates at an end of described limiting tooth 33, axially offers gathering sill 332 in the side of described limiting tooth 33 along rotating shaft 30.Described spring 34 is positioned at the Triaxial hole 325 of second sleeve 32, and an end of spring 34 is held on the ladder of second axis hole 322 and Triaxial hole 325 formation.Described limiting tooth 33 mobilizable Triaxial holes 325 that are positioned at, and the spacing denticle 331 of described limiting tooth 33 deviates from spring 34.Projection 323 in described gathering sill 332 and the Triaxial hole 325 fastens.Described positioning tooth 35 is a torus, end at described positioning tooth 35 is provided with the location denticle 351 that spacing equates, described positioning tooth 35 is fixedly arranged near in first axis hole 311 in first sleeve 31 of Triaxial hole 325, and described location denticle 351 is toward described limiting tooth 33.In the assembling process of described first sleeve 31 and described second sleeve 32, earlier spring 34 and limiting tooth 33 are organized to go in Triaxial hole 325 successively, and gathering sill 332 on the limiting tooth 33 and the projection 323 in second sleeve 32 are fastened, again 35 groups of positioning tooths are gone in first axis hole 311 near first sleeve 31 of limiting tooth 33.Then second sleeve 32 is sheathed between two first sleeves 31, makes described limiting tooth 33 mutually meshing, the protuberance 321 of second sleeve 32 is sheathed in another first sleeve 31 with first sleeve, 31 interior positioning tooths 35.
When the user rotates first body 10, the spacing denticle 331 of the location denticle 351 extruding limiting tooths 33 of described positioning tooth 35, because the projection 323 in the gathering sill 332 of limiting tooth 33 and second sleeve 32 fastens, then limiting tooth 33 can not rotate with respect to second sleeve 32, but limiting tooth 33 can be along the axially-movable of second sleeve 32.When the user acts on pressure on the limiting tooth 33 greater than the elastic force of 34 pairs of limiting tooths 33 of spring by positioning tooth 35, limiting tooth 33 is moved along spring 34 directions, spring 34 is compressed, and limiting tooth 33 is separated with positioning tooth 35, and spacing denticle 331 offsets with the tooth top of locating denticle 351; When the user is rotated further, when spacing denticle 331 will separate with the tooth top of location denticle 351, the acting force of 35 pairs of limiting tooths 33 of positioning tooth disappears, under the effect of the restoring force of spring 34, limiting tooth 33 moves to positioning tooth 35 directions, and the location denticle 351 of described positioning tooth 35 engages again with the spacing denticle 331 of limiting tooth 33, and the motion of restriction positioning tooth 35 makes first body 10 remain on the desired angle of user.Described limiting tooth 33 and positioning tooth 35 separate to engaging from being engaged to again, and have realized the rotation of positioning tooth 35 with respect to the distance of a transverse tooth thickness of limiting tooth 33.In the present embodiment, act on power on the positioning tooth 35 by the deadweight of described first body 10, limiting tooth 33 is separated with the projection 323 in second sleeve 32, then under the effect that does not have external force, the angle between first body 10 and second body 20 is constant.The user in use also can be used in masterpiece on second body 20, realizes the rotation of limiting tooth 33 with respect to positioning tooth 35.By the interaction between the limiting tooth 33 in the described rotating shaft 30, spring 34, positioning tooth 35 and the projection 323, the user not only can change the angle between first body 10 and second body 20 easily, also first body 10 and second body 20 can be remained under the fixed angle.
As Fig. 1, Figure 10 and shown in Figure 11, offer first Electrical Connector Hole 312 between described first sleeve 31 and described first lower cover 12, offer second Electrical Connector Hole 324 between described second sleeve 32 and described second lower cover 22.Described flexible PCB 60 passes second Electrical Connector Hole 324 and arrives in first sleeve 31 through the through hole of second sleeve 32, and then passes first Electrical Connector Hole 312 and arrive in first lower cover 12.Described flexible PCB 60 1 ends electrically connect mutually with printed circuit board (PCB) 50 on being fixedly arranged on second lower cover 22, and the other end electrically connects mutually with ray machine 40 in being placed in first lower cover 12.By flexible PCB 60 being arranged in first sleeve 31 and second sleeve 32, not only can improve the convenience of angular setting between first body 10 and second body 20, can prevent effectively that also first body 10 and second body 20 from causing flexible PCB 60 conductions bad because of long-term bending.
In assembling process, elder generation is fixedly arranged on second lower cover 22 with printed circuit board (PCB) 50 and deviates from a side at battery case 225 places, again flexible PCB 60 is sheathed in second rotating shaft 32, and an end of flexible PCB 60 is passed with printed circuit board (PCB) 50 from second Electrical Connector Hole 324 be connected.Then a side and second lower cover 22 of second loam cake 21 along printed circuit board (PCB) 50 places fixed, battery cover 23 is fastened along a side and second lower cover 22 at battery case 225 places.Form rotating shaft 30 with being fixedly arranged on the two ends that first sleeve 31 on first lower cover 12 is sheathed on second sleeve 32, and the other end of flexible PCB 60 is passed from first Electrical Connector Hole 312, ray machine 40 is fixedly arranged in first lower cover 12 again, and ray machine 40 electrically connected mutually with first Electrical Connector Hole 312, then first loam cake 11 is arranged in first lower cover 12 along the side at ray machine 40 places.
The present invention is by being provided with a rotating shaft between first body and described second body, the user passes through to regulate the relative angle between first body and second body, thereby can change the projecting direction of projection arrangement.
Be understandable that, for the person of ordinary skill of the art, can make change and the distortion that other various pictures are answered by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
