Abstract
The utility model discloses a frame structure of an infrared touch screen. The frame structure is erected at the edge of a touch panel to form the infrared touch screen and comprises a frame, a circuit board and an infrared element, the infrared element comprises a lamp tube and a pin, the pin is welded on the circuit board, a semi-closed cavity for holding the circuit board and the infrared element is formed inside the frame, and the lamp tube extends out from the semi-closed cavity and is attached onto the surface of the touch panel. As the lamp tube is directly attached onto the surface of the touch panel, the distance between the center of the lamp tube and the touch panel is reduced, joined-up writing is not easily caused when a user writes, writing effects are fine, the thickness of the frame is decreased, materials are saved, and cost is reduced.
Description
Technical field
The utility model relates to the touch-screen field, particularly relates to the border structure of the infrared touch panel that a kind of thickness is less.
Background technology
Touch-screen is a kind of multimedia presentation equipment, is the office of modernization multimedia and the requisite equipment of imparting knowledge to students.Wherein the positioning principle of interactive electric whiteboard has multiple, commonly used a kind of be the infrared ray location, it is the scan for networks that forms the horizontal and vertical direction by the infrared receiver and the power valve that gather in the viewing area surrounding, just can be by infrared ray location positioning X, the Y coordinate of the horizontal and vertical direction that is blocked.
Existing infrared touch panel, be generally all that the printed circuit board (PCB) that will infrared components be installed is arranged in frame, so, need in frame, leave the enclosure space of placing infrared components and circuit board.Thus, the center of infrared components has increased the thickness of frame housing to the distance of touch panel, reach 4-5mm, and touch objects does not just trigger touch operation while also encountering touch panel, easily occurs connecting the phenomenon of pen during user writing, and user's experience sense is poor.
The utility model content
Based on this, being necessary provides the border structure of the infrared touch panel that a kind of thickness is less for the prior art problem.
For solving the prior art problem, the utility model discloses a kind of border structure of infrared touch panel, the edge that is erected at touch panel forms infrared touch panel, comprise framework, circuit board and infrared components, described infrared components comprises fluorescent tube and pin, described pin is welded on circuit board, and described framework inside has the semiclosed cavity of a placement circuit board and infrared components, and described fluorescent tube stretches out and is attached to the surface of touch panel in described semiclosed cavity.
Further, described frame ends is provided with filter, and described filter is positioned at the place ahead of infrared components.
Further, described framework is provided with a protuberance, and described protuberance is positioned over the upper surface of described touch panel, and described infrared components is positioned at the place ahead of protuberance.
Further, described protuberance below is provided with a support, and described support is clamped touch panel together with protuberance.
Further, described framework is provided with two draw-in grooves, and described draw-in groove holds and fix described circuit board.
The beneficial effects of the utility model are: framework has the semiclosed cavity of a placement circuit board and infrared components, fluorescent tube can stretch out and be attached to the surface of touch panel in semiclosed cavity, the center and the distance that arrives touch panel of fluorescent tube have been reduced, be not easy to occur connecting the phenomenon of pen during user writing, writing effect is good, and the thickness of framework reduced, also saved material, reduced cost.
The accompanying drawing explanation
The cross section structure schematic diagram of the border structure that Fig. 1 is the utility model infrared touch panel.
Embodiment
For further understanding feature of the present utility model, technological means and the specific purposes that reach, function, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Refer to Fig. 1, the utility model discloses a kind of border structure of infrared touch panel, the edge that is erected at touch panel 10 forms infrared touch panel.The border structure of this infrared touch panel comprises framework 20, circuit board 30 and infrared components 40.Described infrared components 40 comprises fluorescent tube 41 and pin 42, described pin 42 is welded on circuit board 30, described framework 20 inside have the semiclosed cavity 21 of a placement circuit board 30 and infrared components, and described fluorescent tube 41 stretches out and is attached to the surface of touch panel 10 in described semiclosed cavity 21.
Described framework 20 ends are provided with filter 22, and described filter 22 is positioned at the place ahead of infrared components 40, and fluorescent tube 41 emissions or the infrared ray received pass filter 22.
Described framework 20 is provided with a protuberance 24, and described protuberance 24 is positioned over the upper surface of described touch panel 10, and described infrared components 40 is positioned at the place ahead of protuberance 24.
Described protuberance 24 belows are provided with a support 50, and described support 50 is clamped touch panel 10 together with protuberance 24.
Described framework 20 is provided with two draw-in grooves 23, and described draw-in groove 23 holds and fix described circuit board 30.
The border structure of the utility model infrared touch panel, its framework 20 has the semiclosed cavity 21 of a placement circuit board 30 and infrared components 40, fluorescent tube 41 can stretch out and be attached to the surface of touch panel 10 in semiclosed cavity 21, fluorescent tube 41 center and the distance that arrives touch panel 10 have been reduced, just trigger the phenomenon of touch operation while having avoided touch objects also not encounter touch panel, be not easy to occur connecting pen during user writing, writing effect is good, and the thickness of framework has reduced, also save material, reduced cost.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
