For mechanical shutter of the present invention and mobile phone with this mechanical shutter are described further, lift following embodiment and conjunction with figs. and be elaborated.
See also Fig. 1 and Fig. 2, the mechanical shutter 100 that the embodiment of the invention provides comprises a base 10, tumbler 12, blade 14, web member 16, coil 18, one first magnetic element 20, one second magnetic element 22, fastener 24, a stop section 26 and a loam cake 28.
This base 10 roughly is square, also can be circle or the like in other embodiments.Offer one first through hole 101 on this base 10.A drift angle place of this base 10 is provided with a projection 102.
This tumbler 12 is sheathed on this projection 102 and can rotates around this projection 102.
This blade 14 comprises that one is rotated 141 and one at end and this rotation end 141 opposed free ends 142.This rotation end 141 is fixedly arranged on this tumbler 12.This free end 142 is used to cover or appears this first through hole 101.
This web member 16 roughly is " Z " font, and it comprises the supporting part 162 that a fixed part 161 and and this fixed part 161 are parallel.This fixed part 161 is set up and is fixed in this tumbler 12.Be appreciated that this web member 16 and this tumbler 12 structure that can be formed in one.
This coil 18 is fixedly arranged on this supporting part 162.The number of turn of this coil 18 can be set as required.This coil 18 by direct supply (figure do not show) as powered battery.Be appreciated that this coil 18 can be not yet by this web member 16 and directly and this tumbler 12 affixed.Be further appreciated that this coil 18 also can directly link to each other with the rotation end 141 of this blade 14,, when these coil 18 stressed rotations, can drive this blade 14 and rotate for example by bonding mode etc.
This first magnetic element 20 and this second magnetic element 22 are fixedly arranged on the both sides of this coil 18 respectively, but the three is not point-blank.Particularly, this first magnetic element 20 and this second magnetic element 22 are provided with along two limits adjacent with tumbler 12 of base 10 respectively, and wherein, two adjacent limits are two sides that constitute the drift angle that is provided with projection 102.So, can make the more compact structure of this mechanical shutter 100.This first magnetic element 20 and this second magnetic element 22 are permanent magnet, have two magnetic poles.In the present embodiment, this first magnetic element 20 is the N utmost point near the one side of these bases 10, is the S utmost point away from the one side of this base 10.This second magnetic element 22 is the S utmost point near the one side of these bases 10, is the N utmost point away from the one side of this base 10.In these coil 18 galvanizations, this first magnetic element 20 and this second magnetic element 22 make this coil 18 be subjected to the effect of Amp in magnetic field.
This fastener 24 is arranged between this tumbler 12 and this second magnetic element 22 and is positioned at the edge of this base 10, be transformed into when appearing this first through hole 101 from covering this first through hole 101 at this blade 14, this fastener 24 can make this blade 14 not produce in the scope of this base 10.In the present embodiment, this fastener 24 and this base 10 structure that is formed in one.
This stop section 26 is arranged between this first magnetic element 20 and this first through hole 101 and close this first through hole 101.Be transformed into when covering this first through hole 101 from appearing this first through hole 101 at this blade 14, this stop section 26 can avoid this blade 14 to wave excessively, makes this blade 14 remain on the state that covers this first through hole 101.Preferably, this stop section 26 is a cantilever design, and this stop section 26 is fixedly arranged on this base 10 away from an end of this tumbler 12, and the other end can freely swing.So, can more effectively absorb the impulse force of this blade 14.
Be appreciated that this fastener 24 also can be arranged between this tumbler 12 and this first magnetic element 20 and is positioned at the edge of this base 10, simultaneously, this stop section 26 is arranged between this second magnetic element 22 and this first through hole 101 and near this first through hole 101.Preferably, this fastener 24 is made by resilient material, so, can absorb the impulse force of this blade 14.
This loam cake 28 is basic identical with the shape of this base 10, and it offers second through hole 281 coaxial with this first through hole 101.In the present embodiment, this second through hole 281 is all identical with these first through hole, 101 size shape.
See also Fig. 3, (from overlooking the angle of this base 10, behind) the electric current, this blade 14 is in the state that covers this first through hole 101 down together in these coil 18 logical counter clockwise directions.Particularly, can judge that according to left-hand rule Amp that this coil 18 is subjected to this second magnetic element 22 substantially left, the Amp that is subjected to this first magnetic element 20 substantially also left, because this first magnetic element 20 and this second magnetic element 22 are big near the magnetic density of a side of this coil 18, therefore Amp makes a concerted effort substantially left, this blade 14 is subjected to left Amp to anticlockwise, and simultaneously because this stop section 26, this blade 14 is in the state that covers this first through hole 101.
See also Fig. 4, behind these coil 18 clear and coherent conterclockwise electric currents, this blade 14 is in the state that appears this first through hole 101.Particularly, can judge that according to left-hand rule Amp that this coil 18 is subjected to this second magnetic element 22 substantially to the right, the Amp that is subjected to this first magnetic element 20 substantially also to the right, because this first magnetic element 20 and this second magnetic element 22 are big near the magnetic density of a side of this coil 18, therefore Amp makes a concerted effort substantially to the right, this blade 14 is subjected to the right Amp to right rotation, and this blade 14 is in the state that appears this first through hole 101.
To sum up, when needs expose, give these coil 18 clear and coherent conterclockwise electric currents, appear this first through hole 101.After exposure is finished, give this coil 18 logical anticlockwise electric currents, cover this first through hole 101.
Above-mentioned mechanical shutter is by making it the magnetic field interaction with first magnetic element and second magnetic element to coil electricity, thereby driven vane is rotated, the free end of blade is covered or appear first through hole, structure is simpler, small-sized photograph module can be applied to, the shooting effect of small-sized photograph module can be effectively improved.Promptly can be equipped on the photograph module on the mobile phone.Also can be equipped on notebook computer etc. in other embodiments has on the electronic installation of shoot function.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion 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.
