Description
Technical field
The utility model belongs to charactron technical field, and in particular to a kind of charactron with infrared touch function.
Background technique
Existing charactron much has with touch control function, is mainly realized by installation spring or capactive film,
Since the cost of capactive film is very high, so most of producer still can select to pacify spring-loaded mode, but this mode is deposited
As following drawbacks:
1, in use for some time, itself be easily distorted spring deformation, and the structure of spring and position is caused to occur
Deviate, touch function poor contact or even touch function failure occurs;
2, the installation of spring has space size certain requirement, cause the lesser charactron in some inner spaces without
Method meets the installation requirements of spring.
Summary of the invention
Goal of the invention: it in order to overcome the deficiencies in the prior art, provides a kind of by infrared ray generation reflection realization
The charactron of touch function.
Technical solution: to achieve the above object, the utility model provides a kind of charactron with infrared touch function, including
Pcb board, plastic housing and the luminous wick on pcb board are additionally provided with infrared transmitting tube and infrared receiving tube on the pcb board,
The infrared ray that the infrared transmitting tube issues is oblique to be pierced by plastic housing, and the surface of the plastic housing is located at the place setting that infrared ray is pierced by
Have for touching the window for sheltering from infrared ray using finger for finger, the infrared receiving tube is blocked for receiving by finger
The infrared ray reflected, the infrared receiving tube are connected to the driving chip for controlling luminous wick.
Because existing infrared sensing equipment be all using infrared straight line docking by the way of, so that infrared transmitting tube
An opposite is needed to form with infrared receiving tube, due to the limitation of charactron self structure, so that infrared sensing equipment can not
It is applied in charactron and realizes touch function.
The design principle of the utility model are as follows: infrared ray is encountered the technical principle that object emits and answered by the utility model
It has used on the touch function of charactron, using blocking for finger, so that the infrared ray that infrared transmitting tube issues reflects, has led to
The setting to infrared transmitting tube and infrared receiving tube relative position is crossed, the infrared ray reflected is just connect by infrared
Closed tube receives, and infrared receiving tube, which receives, is transferred to driving chip after infrared signal, driving chip control shine the bright of wick with
It goes out and other function.
Further, the infrared transmitting tube and infrared receiving tube are located at the both sides of luminous wick.
Further, the window is located at the top surface of plastic housing, allows people are more intuitive to observe window, and
More convenient finger can be touched on window.
Further, the window is located at the surface for the wick that shines.
Further, the window is square structure, and the side length of the window is less than 8mm, so that window it is big
It is small to match with the size of the finger of people, it is ensured that finger can shelter from the infrared of infrared transmitting tube sending completely
Line avoids therefore occurs the case where touch function failure.It should be noted that the structure of window is also possible to rectangle, circle
Or other irregular shapes.
Further, the angle of the infrared transmitting tube issues infrared ray and window is 45 degree.
The utility model has the advantages that the utility model is compared with prior art, go to touch this movement cooperation infrared ray using finger
Principle of reflection is applied in the middle of charactron, realizes the touch display function of charactron, is breached original infrared induction and is set
The structure space of technical concept and charactron that standby middle infrared transmitting tube and infrared receiving tube must oppose is for infrared emission
The technical bottleneck of the placement constraint of pipe and infrared receiving tube, using this technical implementation way, not only touch function is able to maintain
Steadily in the long term, it effectively, solves original existing deformation because spring itself is easily distorted of the spring-loaded mode of peace, causes
The structure and position for making spring deviate, and the technical issues of touch function poor contact or even touch function failure occur, and
And the realization of touch function is not limited by digital tube space and structure, is carried out suitable for any charactron structure using no
In the presence of the case where not matching is installed, have high widespread popularity, there is good market application value.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after having read the utility model, art technology
Personnel fall within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
As shown in Figure 1, the utility model provides a kind of charactron with infrared touch function, including pcb board 1,2 and of plastic housing
Luminous wick 3 on pcb board 1 is additionally provided with infrared transmitting tube 4 and infrared receiving tube 5 on the pcb board 1, described infrared
The infrared ray that transmitting tube 4 issues is oblique to be pierced by plastic housing 2, and it is useful that the surface of the plastic housing 2 is located at the place setting that infrared ray is pierced by
In touching the window 8 for sheltering from infrared ray using finger for finger, the infrared receiving tube 5 blocks hair by finger for receiving
The infrared ray of raw reflection, the infrared receiving tube 5 are connected to the driving chip 6 for controlling luminous wick 3, the infrared emission
