Background technique
For the project content of desktop or metope etc., if it is desired to using a class product, such as infrared stylus is in projection
Hold and the touch control operations such as directly clicked, slided, pulled, then needs to cooperate infrared camera, infrared stylus and infrared algorithm
It is used together.Specifically, infrared stylus is same as generating infrared signal, is projected by the infrared stylus that infrared camera captures
Infrared signal, the touch data that infrared stylus is generated for desktop or metope is determined, by touch data for projection
Content is operated.
In existing infrared stylus, in infrared light-emitting diode (Light Emitting Diode, LED) periphery using half
Transparent resin forms nib, and the abrasion that so will cause when nib uses is larger.
Summary of the invention
The nib for being designed to provide a kind of infrared stylus of the embodiment of the present invention, to reduce abrasion when using.Tool
Body technique scheme is as follows:
The embodiment of the invention provides a kind of nibs of infrared stylus, comprising:
Infrared light-emitting diode LED light, light guide member and pen tip；Wherein, the material of the pen tip is that hardness satisfaction is default
The material of condition；
Infrared LED lamp is used for when the pen tip comes close to or in contact with touch surface, generates infrared light；
The light guide member is used to the infrared light projecting the touch surface, to form light in the touch surface
Spot.
Optionally, the light guide member is formed by transparent light conductive material.
Optionally, the material of the pen tip includes optical material or non-optical material.
Optionally, the material of the pen tip includes steel or glass.
Optionally, the touch surface includes desktop, metope or writing plane.
The nib of infrared stylus provided in an embodiment of the present invention may include infrared LED lamp, light guide member and pen tip；
Wherein, the material of pen tip is the material that hardness meets preset condition；Infrared LED lamp is used to come close to or in contact with touch surface when pen tip
When, generate infrared light；Light guide member is used to infrared light projecting touch surface, to form hot spot in touch surface.This hair
In bright embodiment, the structure that light guide member is combined with pen tip realizes the light-guiding function of infrared stylus, and pen tip uses hardness
The material for meeting preset condition can reduce abrasion when use.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the nib of provided in an embodiment of the present invention kind of infrared stylus；
Fig. 2 is the structural schematic diagram of specific embodiment provided in an embodiment of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In existing infrared stylus, in infrared LED periphery using translucent resin composition nib, which is by semi-transparent
What bright resin was formed, nib is general relatively thicker, so that abrasion when nib uses is larger.
In order on the basis of realizing infrared stylus leaded light demand, reduce abrasion when nib uses, the present invention
Embodiment provides a kind of nib of infrared stylus.
The nib of infrared stylus provided in an embodiment of the present invention is described in detail below.
The embodiment of the invention provides a kind of nibs of infrared stylus, as shown in Figure 1, may include:
Infrared light-emitting diode LED light 101, light guide member 102 and pen tip 103.
Wherein, the material of pen tip 103 is the material that hardness meets preset condition.
Hardness, which meets preset condition and can be hardness, reaches preset threshold, and specifically preset threshold can be according to actual needs
It determines.It can be hardness alternatively, hardness meets preset condition abrasion can be made when Stylus contact touch surface to reach default wear strips
Part, default abrasive conditions may include make pen tip can not the use duration of normal use reach predetermined time period.Specifically, in advance
If time span can determine according to actual needs.
Infrared LED lamp 101 is used for when pen tip 103 comes close to or in contact with touch surface, generates infrared light.
Light guide member 102 is used to infrared light projecting touch surface, to form hot spot in touch surface.
In the embodiment of the present invention, the structure that light guide member is combined with pen tip realizes the light-guiding function of infrared stylus, and
Pen tip meets the material of preset condition using hardness, can reduce abrasion when use.
As shown in Fig. 2, pen tip 103 generates infrared light when coming close to or in contact with touch surface.Light guide member 102 is used for will
Infrared light projects touch surface 104, to form hot spot 105 in touch surface 104.
Wherein, touch surface may include desktop, metope or writing plane etc..
In a kind of alternative embodiment of the present invention, light guide member is formed by transparent light conductive material.
In the embodiment of the present invention, the structure using transparent light conductive material combination hard material as pen tip is designed, can either
Meet functional guide-lighting requirement, and reduces the abrasion of pen tip.
The enough materials of hardness can be used in pen tip, are not concerned about abrasion when use.
In a kind of optional embodiment, the material of pen tip 103 includes optical material or non-optical material.
In a kind of optional embodiment, pen tip 103 can be metal material, and specifically, the material of pen tip may include
Steel or glass.
In the embodiment of the present invention, pen tip uses the stronger material of hardness, so can reduce the abrasion in use process, can
To reduce the abrasion to nib.And the enough materials of hardness can make pen tip thinner, thinner pen tip can also be reduced to touch-control
The abrasion in face etc..
The embodiment of the invention provides the nib structures that metal penpoint combination transparent light conductive material combines, and can realize
On the basis of light-guiding function, problem easy to wear is reduced, and then can be improved writing experience.And writing fineness can be improved.
