Embodiment

Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below With reference to embodiment, the utility model is expanded on further.

Reference picture 1, a kind of this electronic writing pen nib of the present utility model, including light guide 1 and being fixed with its one end connects The writing contact 2 connect, described one end for being connected with light guide 1 of writing contact 2 are tapered portion 3, one end of the light guide 1 For writing contact 2 described in the light directing that sends light source in electronic writing pen 4, a portion light 5 passes through the writing The conical section of contact is reflected, and reference 6 represents the light of reflection, if penholder is write perpendicular to electronic whiteboard, The light of reflection is mapped to the receiving terminal at electronic whiteboard edge in a manner of parallel to electronic whiteboard.Due to the reflection of tapered portion 3, writing The wide part that light source is sent can be used effectively, because light source major part light is located at light source (being usually LED light source) Optical axis and near, it is very faint directly to the light intensity of electronic whiteboard fringe radiation from light source.Write contact 2 with tapered portion 3 The relative other end is nib, and for directly contacting electronic whiteboard plane, usually spheric, preferred scheme can select POM (polyformaldehyde:Polyformaldehyde) thermoplastic crystalline polymer.It is described as " supersteel " or " match steel ", also known as polyoxy methylene Base.English abbreviation is POM) plus titanium dioxide, the frictional resistance in writing is reduced by the self-lubricitys of POM in itself, adds titanium dioxide It is to strengthen the reflection of light, reduces the loss of light.

Light guide 1 and writing contact 2 can be by UV glue stickings, and the light source that the rear portion of light guide 1 is set can have infrared Light emitting diode and visible ray tri coloured lantern etc.；

As a kind of preferred embodiment, the light guide 1 can be hollow cylinder, and the light that light source is launched is transmitted directly to described Reflected in tapered portion, tapered portion can be made up of infrared light reflection material, can also be by handling the taper of tapered portion Face, one layer of reflecting material is formed on taper surface.

As another preferred embodiment, the light guide 1 is transparent solid cylinder, and the light guide connects with the writing One end that contact element is fixedly connected is recessed taper surface, and the recessed taper surface is engaged with the tapered portion of the writing contact 2, uses UV Glue adheres the two together.

The angle of inclination of the recessed taper surface of the light guide and the tapered portion of the writing contact are appropriately arranged with, allows concave cone The part that light source 4 can be sent formed with space, the recessed taper surface between the tapered portion of shape face and the writing contact Light formed total internal reflection, effect more, as shown in Figure 2.

Described light guide 1 is preferably acrylic material, can also be transparent plastic etc..

The following detailed description of a kind of electronic writing pen of the present utility model, as shown in figure 3, recorded including above example Electronic writing pen nib, in addition to the written written fixing device 8 and light source 4 is fixedly mounted.Light source 4 can simply lead to Cross power supply direct drive.

There is holder 9 in the written fixing device 8, be convenient for changing nib and do not allow nib to come off.

As a preferred embodiment, electronic writing pen also includes pressure sensitive module 12 and connected processor 10, pressure sensitive module 12 can transmit pressure to the pressure sensitive module 12 positioned at the rear end of nib, nib in writing, Pressure sensitive value is sent to processor 10 by pressure sensitive module 12, and parameter is sent to electronic whiteboard, the place by processor 10 Reason device 10 contains the communication module for being communicated with electronic whiteboard, such as bluetooth module.Processor 10 is also associated with multiple open 11 are closed, the transmitting of light source 4 is controlled by receiving different switching signals, light source 4 includes infrared transmitting tube and three-color LED pipe, It is driven by processor.Switch 11 generally selects key switch, and the surface of electronic writing pen is distributed in pictorial diagram, As shown in Figure 4.

Infrared transmitting tube can be lighted always, and it is finger or electronic writing pen to be easy to electronic whiteboard to differentiate touch objects, and three Color LED can show different colors, identify that the color state of three-color LED pipe is sent to by simultaneous processor for user's naked eyes Electronic whiteboard, electronic whiteboard can use corresponding color pencil according to the color state of three-color LED pipe.User is allowed to have more easily Experience, in writing, dispense the step of selecting color pencil.

As a preferred embodiments, the holder 9 can live in the certain space in the written fixing device 8 Move, such as one millimeter of scope of activities, the pressure sensitive module 12 are located at the rear end of holder 9.

Electronic whiteboard receives the thickness that stroke can be adjusted after pressure sensitive value, makes the writing of writing out vigorouser Effectively, more added with artistic feeling.

The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model Claimed scope is by appended claims and its equivalent thereof.
