Description
Technical field
The invention belongs to charactron technical fields, and in particular to a kind of charactron with infrared touch function.
Background technology
Existing charactron much has with touch control function, is mainly realized by installing 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, the charactron for causing some inner spaces smaller without
Method meets the installation requirements of spring.
Invention content
Goal of the invention：In order to overcome the deficiencies in the prior art, provide a kind of by infrared ray generation reflection realization
The charactron of touch function.
Technical solution：To achieve the above object, the present invention provides a kind of charactron with infrared touch function, including PCB
Plate, plastic housing and the luminous wick on pcb board are additionally provided with infrared transmitting tube and infrared receiving tube on the pcb board, described
Infrared ray that infrared transmitting tube is sent out is oblique to be pierced by plastic housing, and it is useful that the surface of the plastic housing is located at the place setting that infrared ray is pierced by
In touching the window for sheltering from infrared ray using finger for finger, the infrared receiving tube blocks generation for receiving by finger
The infrared ray of reflection, 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 present invention design principle be：Infrared ray is encountered the technical principle that object emits and has been applied to number by the present invention
On the touch function of code pipe, blocking for finger is utilized so that the infrared ray that infrared transmitting tube is sent out reflects, by infrared
The setting of transmitting tube and infrared receiving tube relative position so that the infrared ray reflected can just be connect by infrared receiving tube
It receives, infrared receiving tube is transferred to driving chip after receiving infrared signal, and driving chip controls the light on and off for the wick that shines, and
Other functions.
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 so that and people can more intuitively 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 length of side 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 completely infrared transmitting tube send out it is infrared
Line avoids therefore the case where touch function failure occurs.It should be noted that the structure of window can also be rectangle, circle
Or other irregular shapes.
Further, the angle for the infrared ray and window that the infrared transmitting tube is sent out is 45 degree.
Advantageous effect：Compared with prior art, the present invention going to touch this reflection for acting cooperation infrared ray using finger
Principle is applied in the middle of charactron, is realized the touch display function of charactron, is breached in original infrared sensing equipment
The structure space for the technical concept and charactron that infrared transmitting tube and infrared receiving tube must oppose for infrared transmitting tube and
The technical bottleneck of the placement constraint of infrared receiving tube, using this technical implementation way, not only touch function can be kept long-term
Stablize, effectively, solves original existing deformation because spring itself is easily distorted of the spring-loaded mode of peace, cause bullet
The structure of spring and position are deviateed, and the technical issues of touch function poor contact or even touch function failure occur, and touch
The realization for touching function is not limited by digital tube space and structure, is used, is not present suitable for any charactron structure
The case where not matching is installed, has high widespread popularity, there is good market application value.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
It the present invention rather than limits the scope of the invention, after having read the present invention, those skilled in the art are to of the invention each
The modification of kind equivalent form falls within the application range as defined in the appended claims.
As shown in Figure 1, the present invention provides a kind of charactron with infrared touch function, including pcb board 1, plastic housing 2 and it is located at
Luminous wick 3 on pcb board 1 is additionally provided with infrared transmitting tube 4 and infrared receiving tube 5, the infrared emission on the pcb board 1
Infrared ray that pipe 4 is sent out is oblique to be pierced by plastic housing 2, and the surface of the plastic housing 2 is located at the place that infrared ray is pierced by and is provided with for supplying
Finger touches the window 8 that infrared ray is sheltered from using finger, and the infrared receiving tube 5 blocks generation instead for receiving by finger
The infrared ray penetrated, the infrared receiving tube 5 are connected to the driving chip 6 for controlling luminous wick 3, the infrared transmitting tube 4
