Description
[technical field]
The utility model relates to a kind of framed structure, particularly a kind of frame structure of infrared touch panel.
[background technology]
The ultimate principle of infrared touch panel is to be calculated touch point position by the infrared ray grid that detects in the viewing area by the situation that barrier blocks, and its basic structure generally constitutes by being located at the structural member that polylith around the viewing area is welded with the circuit board of infrared emission tube and infrared receiver tube and is used for fixing circuit board.
By the principle of work of infrared touch panel and form structure and be not difficult to learn, realize infrared touch panel can operate as normal, easy to maintenance, produce in enormous quantities, must the project organization compactness, enough big, the production easily of optical channel, easy-to-install frame structure spare.
The part infrared touch screen products that existing market occurs, in the design of structural member, take to open a plurality of through hole modes and satisfy the demand that infrared touch panel optical channel and structure are installed in the side of Infrared outgoing, the through hole of this continuous processing needs more manufacturing procedure, not only increased the difficulty of processing of structural member, improved production cost, and be difficult to realize bias free because the positional precision of light hole is subject to processing the influence of technology, cause whole touch screen to produce debugging and daily servicing difficulty thus.
In addition, Chinese patent discloses a kind of infrared touch panel housing of being made by filter for No. 200520004942.3, adopt the structural member of the tubing of flat hollow, adopt this scheme, though the structural member production and processing is simple as fixing circuit board, cost is lower, but when installing, circuit board must could begin debugging by the end to end structural member of putting into fully of all circuit boards, and in case need to safeguard that then must break whole touch screen just can carry out, the Installation and Debugging process is inconvenience very, the maintenance cost height.
[summary of the invention]
The purpose of this utility model is to provide a kind of light channel not have blocks, Installation and Debugging are convenient, maintenance cost is low, handling ease, compact conformation, weight is light, penetrability is high touch-screen framework.
For realizing the utility model purpose, provide following technical scheme:
A kind of touch-screen framework is provided, it comprises underframe, face frame and light transmission piece, leave the fixedly step of infrared touch panel circuit board assemblies on underframe and/or the face frame, the relative groove of offering in medial extremity limit of underframe and face frame, light transmission piece places the groove between underframe and the face frame.Underframe or face frame are provided with supporting construction and/or draw-in groove structure and are used for supporting surface frame or underframe.
Supporting construction on this underframe or the face frame is L shaped or T shape or rectangle or other are applicable to the shape of supporting construction.Supporting construction is the part of face frame or underframe, with face frame or underframe be an integral body, can set the position of existence according to the element shapes of circuit board flexibly, to not needing to keep the position of supporting construction, can remove.
The step of reserving on described underframe and/or the face frame that is used for fixing circuit board assemblies can be determined height and width according to actual needs.This face frame can be kept somewhere cavity, is used for containment circuit board assembly part vigour part pin, prevents to cause the short circuit of circuit.Thereby this cavity can be formed between step by the step setting on underframe and/or the face frame.
Can link to each other and/or bonding mode be connected by securing member between described underframe and the face frame, described securing member can be a screw, rivet or other tightening member.Described frame or underframe also can adopt the draw-in groove structure to connect, and can not use securing member or bonding way to be connected between face frame and the underframe, and by on underframe or the face frame respectively the supporting construction of setting match with the draw-in groove structure and be connected.Described supporting construction can be L shaped or T shape.
The utility model touch-screen framework compared with prior art has the following advantages:
1, except light transmission piece, block in the optical channel, and light transmission piece can reach more than 50% for ultrared transmitance, therefore preferably resolve the problem that frame structure spare influences the infrared light passage without any structural member;
2, the circuit board Installation and Debugging are convenient and swift.Face frame and underframe relative separation, circuit board are installed on underframe or the face frame, do not need to seal whole housing like this when Installation and Debugging infrared touch circuit board, make things convenient for staff's Installation and Debugging, sealing again after Installation and Debugging are finished;
3, frame structure compactness, volume is little, and is in light weight, is fit to the embedded display device that is installed to.
4, production and processing is simple, does not need complicated manufacturing procedure, and is with low cost, realizes easily producing in enormous quantities;
5, the favorable expandability of frame structure, display size scope applicatory is wide, both can be used for the display device about 17 o'clock, also can be used for 100 o'clock or larger sized display device;
