The structural representation of another part assembly among hand-written time writing device one embodiment that Fig. 3 provides for the utility model.Nib assembly, copper pipe 35, movable contact element and copper pin 38 have been shown among Fig. 3, and these assemblies all are positioned at enclosure interior.All component shown in Fig. 3 has constituted the signal control component of time writer.
Specifically, the nib assembly is made up of nib 31 and copper post 32.Wherein nib 31 is the cone-shaped body structure, and copper post 32 is the thin bar structure of diameter less than cone-shaped body bottom surface diameter.Preferably, the nib assembly is by wear-resisting polyoxymethylene (Polyoxymethylene, be called for short: the coated moulding in plastic injection mold of nib 31 POM) and copper post 32, promptly adopt the method for coated moulding in plastic injection mold, make the nib 31 of wear-resisting POM material be integrated and form the nib assembly with copper post 32 with higher-strength.Adopt the method for coated copper post 32 in the injection mold to make nib 31 heads adopt wear-resisting POM material to reach good and write impression and the protection of screen; nib 31 is one-body molded with 0.8mm diameter copper post 32; improved the anti-performance that fractures of nib, created advantage for dwindling time writer 1 diameter.Coiling magnetic core 12 shown in Fig. 2 can be provided with around copper post 32, and is fixed on the housing.
Copper pipe 35 is a thin-walled column tubular, has first end and the second end, and the nib assembly is connected with the first end of copper pipe 35.The wall thickness of copper pipe 35 is about 0.15mm, and this makes that also the diameter of time writer 1 can be littler.Copper pin 38 is the buttress shaft shape, has first end and second end; First end of copper pin 38 is connected with the second end of copper pipe 35 by movable contact element; Second end of copper pin 38 and circuit board 13 welding.
In the embodiment shown in fig. 3, movable contact element specifically comprises spring electrode 34, electric silica gel 36 and electric capacity magnetic sheet 37.Wherein spring electrode 34 is centered around the outside surface of copper pipe 35.Electric silica gel 36 is cylindric, and the one end is an inserted terminal, is plugged on the second end of copper pipe 35; First end of copper pin 38 is fixedlyed connected with electric capacity magnetic sheet 37; Electric capacity magnetic sheet 37 is affixed with housing 11, and electric silica gel 36 contacts with electric capacity magnetic sheet 37 when nib assembly pressurized.
One end of spring electrode 34 extends to circuit board 13, and welds with circuit board 13.Particularly, with an end of the spring electrode 34 of circuit board 13 welding can be one section straight lead, promptly an end of spring electrode 34 prolongs and one section straight wire bonds on circuit board 13.One end of spring electrode 34 also can be welded on the circuit board 13 by a section lead, i.e. an end of spring electrode 34 and section lead welding, and the other end of this lead is welded on the circuit board 13.
Further, embodiment shown in Figure 3 can also comprise copper pipe web member 33, this copper pipe web member 33 is arranged between the first end of nib assembly and copper pipe 35, and promptly the nib assembly is connected with an end of copper pipe web member 33, and the other end of copper pipe web member 33 is connected with the first end of copper pipe 35.Preferably, nib assembly and copper pipe web member 33 can be the interference fit syndeton, and promptly the nib assembly inserts the internal diameter of the diameter of copper pipe web member part more than or equal to copper pipe web member opening portion.After writing use wearing and tearing nib, can the nib assembly be extracted from copper pipe web member 33 from time writer 1 front end, change to new nib assembly and continue to use.
When time writer nib 31 contacts pressurized with touch screen 2, by the nib assembly, copper pipe web member 33, spring electrode 34, copper pipe 35, electric silica gel 36, the signal control component that electric capacity magnetic sheet 37 and copper pin 38 are formed is started working, its concrete course of work is as follows: nib 31 effect of being stressed promotes the nib assembly, copper pipe 35, electric silica gel 36 and spring electrode 34 move jointly, when electric silica gel 36 moves to when contacting with electric capacity magnetic sheet 37, time writer signal controlling module by signal is via copper pin 38, electric capacity magnetic sheet 37, electric silica gel 36, copper pipe 35 and spring electrode 34 input to time writer LC oscillating circuit part, form capacitance variation, and finally cause change of resonance frequency; Owing to electric silica gel 36 and electric capacity magnetic sheet 37 contacts area along with nib 31 pressures increase, and the capacitance of electric capacity magnetic sheet 37 changes with the variation of contact area, finally forms hand the pressure of nib 31 is changed the continuous variation that is converted into time writer 1 transmission frequency; Nib 31 pressure are eliminated when not being in touch-control or writing state, and under the effect of spring electrode 34 elastic force, electric silica gel 36 separates with electric capacity magnetic sheet 37, and the touch-control and the state of writing finish.
The float electrode that the hand-written time writing device that the utility model provides adopts copper pipe and spring electrode to form, the nib assembly of wear-resisting POM material damascene copper post, excitation electromagnetic wave signal by the touch screen generation, after the LC oscillating circuit part of time writer forms induced electromotive force, by capacitance energy storage, coil by time writer sends out electromagnetic signal, information such as feedback time writer position and pressure variation, final formation hand changes the continuous variation that is converted into the time writer transmission frequency to the pressure of nib, has reached time writer and has write the technique effect of pressure sensitivity.
In the hand-written time writing device that the utility model provides, one of the building block that nib assembly, copper pipe web member, copper pipe and spring electrode constitute act as the signal of connecting flow through copper pin, electric capacity magnetic sheet, electric silica gel, copper pipe and spring electrode when the nib pressurized moves, another act as after pen point pressure disappears, and time writing device resets under the effect of spring force.Wherein, wear-resistant material POM nib and copper post are that the nib assembly is formed in coated moulding in the injection mold, have higher strength of joint and accurate mutual bearing accuracy, the fracture of nib when preventing time writer use and unexpected dropping, the wear-resisting and lubricating property of nib can guarantee that also time writer has the good impression of writing; Nib assembly and copper pipe web member adopt over-surplus fit structure, and after writing the use wearing and tearing, replaceable nib assembly continues to use.The advantage that hand-written time writing device diameter is little, nib intensity is high that the utility model provides is significant to reducing electronic reader and the dull and stereotyped computer product thickness of using electromagnetism touch-control scheme.
At last; it should be noted that: more than what enumerate only is specific embodiment of the utility model; certainly those skilled in the art can change and modification the utility model; if these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, all should think protection domain of the present utility model.
