Technical field
The utility model relates to the touch TV domain, specifically is meant the lcd touch TV, refers to a kind of LCD TV of assembling the infrared touch screen assembly especially.
Background technology
Along with science and technology development, the appearance of electronic touch technology, touch-screen has also experienced from the bottom and has moved towards high-end development course, develops so far, and the touch-screen of various technology emerges in an endless stream, and its performance is constantly perfect.Because simple in structure, easy to use and reaction speed is fast, save the space and be easy to plurality of advantages such as man-machine communication, at present to be widely used in fields such as communal facility, Industry Control, military commanding, electronic game, multimedia teaching.
Compare with other touching technique, the infrared ray touching technique has advantageous advantage, it has and does not wear and tear, is not subjected to electric current, voltage and electrostatic interference, long service life, stablely do not have drift, anti-riot, antifouling a, plurality of advantages such as waterproof can be worked under some rugged environment, in addition; Utilize infrared ray can also be very easy to produce the touch-screen of super large-scale, making infrared touch panel be a dark horse more and more becomes the main product in touch-screen market.
In recent years along with the maturation of large-sized infrared touch panel and large scale liquid crystal TV tech, some strong producers just are combined in one with infrared touch panel and LCD TV, concrete combination is directly the infrared touch panel circuit board to be sticked on around the screen surface of LCD TV, and be pasted with the light transmission strip that can see through infrared ray in the place ahead of this circuit board, so just can before display screen, form an infrared ray and touch surveyed area, the touch target is caught with this in the back that links to each other with computer, make it become a lcd touch TV, therefore be widely used in all trades and professions, when this lcd touch TV brings convenience with visual enjoyment to the user; Many troubles have also been caused, because circuit board is directly to cement around the LCD TV screen surface, though it is simple in structure, be easy to production and processing, cost is also the end of than, but such structure is to the installation of whole infrared touch panel circuit board, debugging brings very big inconvenience, in case even more serious is that will be difficult to take off maintenance unusually and safeguarding appears in the touch-screen detection, whole TV can only be transported anti-factory when having more serious problem to need the maintenance of anti-factory as touch-screen, also because the infrared touch panel circuit board assemblies directly contacts the LCD screen surface, the factors such as temperature of components and parts separately can influence operate as normal separately in the course of the work, also can influence useful life separately, increased user's use cost so virtually, get in touch defective tightness around light transmission strip and the LCD TV screen surface, be easy to generate the slit and directly influenced its waterproof, dustproof function let alone explosion-proof, therefore be necessary the infrared touch panel and the mounting means of existing assembling LCD TV are improved, make it be easy to install, debugging, maintenance and maintenance, and can reach explosion-proof, waterproof, the dustproof purpose.
Summary of the invention
In order to overcome the existing deficiency of above-mentioned infrared touch LCD TV, the purpose of this utility model is to provide a kind of infrared touch screen assembly that assembles LCD TV, this infrared touch screen assembly of LCD TV fit on not only is easy to install, debugging, convenient maintenance and safeguard and can reach purpose explosion-proof, waterproof and dustproof.
The utility model in order to achieve the above object, the technical scheme that is adopted is: comprise a LCD TV and an infrared touch screen assembly, described infrared touch screen assembly comprises an infrared touch panel circuit board assemblies and a light transmission piece that the housing that mates with LCD TV screen size is interior with being installed on the housing cavity, and described infrared touch screen assembly just is installed in LCD TV screen the place ahead.
In order better to understand this patent, the utility model also has following concrete technical scheme:
Described housing fixedly is made of by four contiguous blocks four flat profile two ends, described flat profile is made of face-piece and drain pan respectively, and the relative printing opacity film trap of offering on the inner side edge of face-piece and drain pan, light transmission piece just places the printing opacity film trap between face-piece and the drain pan, solve the defective tightness of getting in touch around light transmission strip and the LCD TV screen surface with this, being easy to generate the slit has directly influenced the deficiency of its waterproof and dustproof, also offer a glass guide channel on the inner side end of drain pan, toughened glass just places the glass guide channel of drain pan; Strengthen its explosion prevention function with this, the drain pan inner surface of infrared touch screen assembly offers the draw-in groove of being convenient to place the infrared touch panel circuit board assemblies, and the infrared touch panel circuit board assemblies just is fixed in the draw-in groove by screw or rivet; The outer side edgefold of the face-piece of infrared touch screen assembly and drain pan is interlocked, and the shape of cross section after fastening is all L-shaped; The face-piece of described infrared touch screen assembly and drain pan through screw in the side or the front be connected and fixed.
Described infrared touch screen assembly before connector is locked in the LCD TV screen with screw threads, and through connector with screw locking in front shell of television or separately with the infrared touch screen assembly through connector by screw locking in front shell of television.
Offer one on the contiguous block face of described infrared touch screen assembly for connecting the winding displacement passage that each infrared touch panel circuit board assemblies winding displacement passes through.
Owing to adopted above-mentioned technical scheme: be separately fixed at the infrared touch panel circuit board assemblies in the draw-in groove of four foundation shells by screw earlier during the assembling infrared touch panel, then with four face-pieces respectively correspondence be interlocked on four foundation shells, and be fixed by some screws and form four flat section bars, light transmission piece places the printing opacity film trap between face-piece and the drain pan, four limit correspondences of a toughened glass are inserted in four glass guide channels of drain pan inner side end, two ends with face-piece are screwed rectangle infrared touch panel housing of formation by four contiguous blocks respectively then, connect in the just corresponding respectively winding displacement passage that is placed on the contiguous block face of winding displacement of each piece infrared touch panel circuit board assemblies, effectively avoid twining the problem that causes loose contact because of winding displacement, so just finished the assembling of whole infrared touch screen assembly, the good infrared touch screen assembly of debugging before connector is locked in the LCD TV screen with screw threads, and through connector with screw locking in front shell of television or separately with the infrared touch screen assembly through connector by screw locking in front shell of television; Again the forward and backward shell of television set is loaded onto the assembling of promptly having finished whole lcd touch TV.
Lcd touch TV of the present utility model is compared with existing lcd touch TV to have: not only be convenient to installation, debugging to infrared touch panel, also help at touch-screen and detect maintenance and maintenance when unusual, good airproof performance does not have the slit between light transmission piece and toughened glass and the housing; Reach requirement explosion-proof, waterproof and dustproof.
