Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, each embodiment of the present utility model is explained in detail.But, persons of ordinary skill in the art may appreciate that in each embodiment of the utility model, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following embodiment and amendment, each claim of the application technical scheme required for protection also can be realized.
First embodiment of the present utility model relates to the time writer that a kind of nib improves, and concrete structure as shown in Figure 2.The time writer 1 that nib improves comprises housing 10, support 11, circuit board 12, first magnetic core 13, second magnetic core 14, elastic component 15, inductive coil 16, nib 17, pen cap 18 and spring 19.Wherein, support 11, circuit board 12, first magnetic core 13, second magnetic core 14, elastic component 15, inductive coil 16, spring 19 are all arranged in housing, and nib 18 is exposed to the opening 101 of housing 10 one end.
In the first embodiment, the first magnetic core 13, second magnetic core 14, elastic component 15, inductive coil 16, nib 17 and spring 19 form electromagnetic induction assembly.Inductive coil 16 is set around the first magnetic core 13, and nib 17 is shaped in the first magnetic core 13, and elastic component 15 is arranged between the first magnetic core 13 and the second magnetic core 14.Wherein, the first magnetic core 13 and the second magnetic core 14 are such as FERRITE CORE, and elastic component 15 is such as silicagel pad; But the utility model does not impose any restrictions this.
Specifically, nib 17 is shaped in the first end of the first magnetic core 13, and namely nib 17 and the first magnetic core 13 are once molded in a mould forming, and therefore nib 17 is made up of identical material with the first magnetic core 13, such as, be Ferrite Material.Thus nib 17 can be regarded as the first extension of magnetic core 13 in length, nib 17 and the first magnetic core 13 form a whole magnetic core and act on inductive coil 16.According to electromagnetic induction principle, when other condition is constant, the length of magnetic core is longer, and the induction current produced in inductive coil is larger.Therefore, the induction current that described whole magnetic core acts on inductive coil 16 and produces, will obviously be greater than the induction current only being acted on inductive coil 16 and generation by the first magnetic core 13.
Elastic component 15 is held between the second end of the first magnetic core 13 and the first end of the second magnetic core 14.Can there is corresponding elastic deformation according to the change of the external force putting on nib 17 in elastic component 15, thus change the relative distance between the first magnetic core 13 and the second magnetic core 14.
Spring 19 is set around the second magnetic core 14 and elastic component 15.Wherein, the elasticity coefficient of spring 19 is less than the elasticity coefficient of elastic component 15.When external force puts on the first magnetic core 13 by nib 17, will there is compression set prior to elastic component 15 in spring 19.
In the first embodiment, support 11 is fixed in housing 10, and its fixed form does not impose any restrictions at this.Support 11 can be divided into two parts, and Part I is in order to locating circuit board 12, and Part II is in order to limit the start of electromagnetic induction assembly.
Specifically, the Part I of support 11 comprises two location divisions be oppositely arranged 111; Circuit board 12 has two relative positioning portions 121, corresponds respectively to described two location divisions 111.Circuit board 12 is positioned support 11 by two location divisions 111 with coordinating of two relative positioning portions 121.Wherein, location division 111 and relative positioning portion 121 are such as the combination of protuberance and groove, but the utility model does not impose any restrictions this.
The Part II of support 11 comprises stopper section 112 and limiting section 113, and the two forms holding part 114 jointly with accommodating and spacing electromagnetic induction assembly.Wherein, the second end of the first magnetic core 13 has boss 131, and the boss 131 that limiting section 113 is held in the first magnetic core 13 moves towards the direction of nib 17 to limit electromagnetic induction assembly; The first end of spring 19 is held in the boss 131 of the first magnetic core 13 and its second end is held in stopper section 112; Stopper section 112 corresponds to the second end of the second magnetic core 14, and second end that can support the second magnetic core 14 moves to limit the electromagnetic induction assembly direction in nib 17 towards the opposite.
Specifically, when applying pressing force to nib 17, the electromagnetic induction assembly direction in nib 17 towards the opposite is moved, and spring 19 produces compression set; When spring 19 is compressed to a certain degree, the second end of the second magnetic core 14 is held in stopper section 112 and cannot continues the direction in nib 17 towards the opposite and moves; Continue to apply pressing force to nib 17, elastic component 15 produces compression set and then reduces the relative distance between the first magnetic core 13 and the second magnetic core 14, thus makes the em induced current that changes in inductive coil 16.
Set-up mode for spring in the utility model is not limited to this.In other embodiment, the first end of the second magnetic core also can have boss, and spring is set around the second magnetic core, and the first end of spring is held in the boss of the first end of the second magnetic core and the second end of spring is held in stopper section; Or the second end of the second magnetic core also can have boss, the first end of spring is held in the boss of the second end of the second magnetic core and the second end of spring is held in stopper section.
In the first embodiment, pen cap 18 is such as made of plastics, and it at least comprises the hollow tube 181 with one end enclosed construction, to be sheathed on nib 17 tightly.Further, pen cap 18 can also comprise neck 182, and it is connected to the other end of hollow tube 181 and its external diameter is greater than the diameter of opening 101.Thus neck 182 can be arranged in housing 10 and cannot skid off from opening 101, pen cap 18 is firmly sheathed on nib 17 and can not landing by neck 182.In time operating the time writer 1 that nib improves, the operating surface of the direct contacting electronic equipments of pen cap 18, can improve the operation feeling of user well.
