Another preferred embodiment of the present invention is one to have writing function type electromagnetic induction pen device.Above-mentioned have writing function type electromagnetic induction pen device and comprise an electromagnetic induction device, a writing device, and a support frame is between electromagnetic induction device and writing device.Fig. 2 is a synoptic diagram according to the writing function type electromagnetic induction pen device of having of present embodiment.With reference to figure 2, above-mentioned electromagnetic induction device 201 comprises one first coil 211 of one first flexible member 205, one first hollow sleeve 206, one first magnetic element 207, one second magnetic element 208, one first sliding part 209, one first pen core 210 and at least one strand institute coiled at least.Above-mentioned writing device 250 comprises one second coil 261 of one second flexible member 255, one second hollow sleeve 256, one the 3rd magnetic element 257, one the 4th magnetic element 258, one second sliding part 259, one second pen core 260 and at least one strand institute coiled at least.
Fig. 3 A is the diagrammatic cross-section according to the writing function type electromagnetic induction pen device of having of present embodiment, and Fig. 3 B is according to the writing function part exploded view of having of present embodiment.With reference to figure 3A and Fig. 3 B, at electromagnetic induction device 201 ends, an end of support frame 204 has one first skeleton lid 212.Between these first skeleton lid, 212 definition one first are held, for ccontaining first flexible member 205.This first flexible member 205 can be a spherical flexible member, for example, and a rubber sphere.First hollow sleeve 206 is hollow cylindrical, and has one first outside surface 213 and one first inside surface 214.One end of first hollow sleeve 206 is resisted against the first skeleton lid 212, and the other end is provided with a pair of first terrace 216, and wherein one first terrace 216 engages mutually with shell body 202, makes the hollow sleeve 206 of winning be subjected to the fixing of shell body 202.With reference to figure 3B, an end of first hollow sleeve 206 has one group of recessed structure, in order to one group of projective structure of the ccontaining first skeleton lid 212 when assembling.Be provided with one first ring-type spacing body 215 in first inside surface 214 of first hollow sleeve 206, first hollow sleeve 206 is separated into one first room and one second room, wherein second room is formed between the first ring-type spacing body 215 and the first skeleton lid 212.The first ring-type spacing body 215 is integrally formed with first hollow sleeve 206.First magnetic element 207 has one first central perforation, and the engaging of one end is placed in first room and is resisted against on the first ring-type spacing body 215.First magnetic element 207 is in electromagnetic induction device 201 is fixed in setting.Second magnetic element 208 has one second central perforation.Second magnetic element 208 is placed in second room movably, and the one end is resisted against on the first ring-type spacing body 215.First magnetic element 207 and second magnetic element 208 can be formed by powdered-iron core or high magnetic conductive material.In a preferable example, the length of first magnetic element 207 is greater than the length of second magnetic element 208.
First sliding part 209 is placed in second room movably.With reference to Fig. 3 A and Fig. 3 B, first sliding part 209 has a cylinder-shaped body.The inside of first sliding part 209 can be separated into a first end and a second end, and wherein the second end is near the first skeleton lid 212.Second magnetic element 208 can be placed within the first end of first sliding part 209.In assembling, second magnetic element 208 and first sliding part 209 that are placed in the first end of first sliding part 209 are placed in second room of first hollow sleeve 206 movably, and the one end is resisted against on the first ring-type spacing body 215, in order to second magnetic element 208 along with first sliding part 209 slides up and down in first hollow sleeve 206.The first end length of first sliding part 209 is slightly less than the length of second magnetic element 208, makes between the first ring-type spacing body 215 of the first end of the sliding part 209 of winning and first hollow sleeve 206 and can keep a minim gap.This minim gap is reserved by the length tolerance of second magnetic element 208.That is to say, spacing between the first ring-type spacing body 215 of the first end of first sliding part 209 and first hollow sleeve 206 must be slightly larger than the length of second magnetic element 208, so that second magnetic element 208 of this spacing in can ccontaining length tolerance permissible range, so, then the relative distance of first magnetic element 207 and second magnetic element 208 is just for fixing.With reference to Fig. 3 A, inner one the 3rd room that forms of the first end of first sliding part 209 is for an end of ccontaining clamping first pen core 210.First sliding part 209 can drive second magnetic element 208 when mobile synchronously in second room.The second end of first sliding part 209 is resisted against an end of first flexible member 205.
With reference to Fig. 3 C, it is the user mode sectional view according to wireless pen for digital 201 of the present invention, and when first pen core 210 was write on digiboard 3, digiboard 3 upwards applied a strength, make first pen core 210 and first sliding part 209 move up synchronously, and then oppress first flexible member 205.At this moment, second magnetic element 208 is also driven synchronously by first sliding part 209 and moves up, and its relative position with first magnetic element 207 is changed, and then makes the inductance value reduction of first coil 211.Bigger when second magnetic element 208 to top offset, the inductance value of first coil 211 is just fallen lowlyer, its with the resonant frequency of resonant circuit then more greatly.Second magnetic element 208 moves up, and can change the inductance value of first coil 211, and resonant frequency also with change, at this moment, first coil 211 is promptly wirelessly launched the electromagnetic field signal of frequency change, digiboard 3 is received and produces induced voltage.
When no external force upwards acted on first pen core 210, first flexible member 205 provided an elastic force to give first sliding part 209, so that first sliding part 209 and second magnetic element 208 are resisted against on the first ring-type spacing body 215 simultaneously.Moreover, be not subjected to digiboard 3 upwards under the strength effect at first pen core 210, distance between first magnetic element 207 and second magnetic element 208 is determined by the thickness of the first ring-type spacing body 215, can be maintained fixed, can not influence the accurate control of relative position between the two because of the finished product length tolerance value of first magnetic element 207 and second magnetic element 208.So, when first pen core 210 one upwards under the external force effect, the frequency output valve of wireless pen for digital 200 can be fixed.
In electromagnetic induction device 201 according to the present invention, first coil 211 of one line institute coiled at least directly is wrapped on the outside surface of first magnetic element 207.First coil 211 has splendid Q value, and the ability of its emission electromagnetic field and induction field is all very strong.When digiboard 3 changes at the pressure of detecting wireless pen,, and make when digiboard becomes pressure with conversion of signals more true because of signal/noise makes resolution also improve than improving.Moreover, can directly absorb the electromagnetic field of digiboard 3 emission by first coil 211, being made for its electric power, and do not need additionally to use battery that electric power is provided.
