Description
Technical field
The utility model relates to the touch screen technology field, particularly the posting fixed mount of infrared touch panel.
Background technology
Common infrared touch panel 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 can know, structural member for infrared touch panel, it is enough big to reach light channel, convenient for installation and maintenance, the basic demand of the simple grade of production and processing, could satisfy the function and the outward appearance demand of infrared touch panel, realize producing in enormous quantities.Wherein, because 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, therefore do not having under the situation about touching, must guarantee that the light that infrared emission tube sends still has enough intensity when arriving infrared receiving tube through the viewing area, thereby can make receiving tube be converted into available electric signal, so, on the structural member of fixing circuit board, must reserve the passage of enough big space as Infrared.
The part infrared touch screen products that existing market occurs, in the design of structural member in order to guarantee optical channel, taked the side of Infrared outgoing on frame structure spare to open the mode of a plurality of through holes, this measure has not only increased the difficulty of processing of structural member, improved production cost, and, cause whole touch screen to produce debugging and daily servicing difficulty easily because the positional precision of light hole is difficult to assurance.
In addition, the patent No. is that 200520004942.3 Chinese patent " a kind of infrared touch panel housing by unitized construction " discloses a kind of infrared touch panel housing of being made by filter, adopt the structural member of the tubing of flat hollow as fixing circuit board, adopt this scheme, though the structural member production and processing is simple, cost is lower, but the circuit board Installation and Debugging are inconvenience very, in case need to safeguard, then must break whole touch screen, the maintenance cost height.
Also have, the circuit board of most of in the market infrared touch product all is to adopt the mode of two-sided sticker to be fixed on the frame, and in the time of maintenance, circuit board is difficult to remove from frame, operates cumbersome, difficult.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of prior art, and the big and Installation and Debugging of a kind of light channel posting fixed mount of infrared touch panel easily is provided.
The technical solution of the utility model is: a kind of posting fixed mount of infrared touch panel, it is the quadrilateral structure that four housing assemblies are fixedly connected sequentially and constitute by four connectors, each housing assembly inboard is provided with the semiclosed cavity that is used for mounting circuit boards, and its opening is towards housing assembly inboard; The inside edge of each housing assembly also offers the groove that is used for fixing the infrared light passage device.
The described bottom that is used for the semiclosed cavity of mounting circuit boards is distributed with the double-screw bolt that is used for fixing circuit board, and semiclosed cavity top is set to be used for the plate washer of holding circuit plate; Described circuit board is fixedlyed connected with described double-screw bolt by screw, both fixing circuit boards effectively, and the electric part that effectively prevents circuit board again contacts with the housing assembly and causes short circuit.
Described infrared light passage device comprises light transmission piece, light transmission piece joint, and each light transmission piece is rabbeted with the groove of corresponding housing assembly inside edge respectively, and fixedlys connected with corresponding housing assembly by screw or double faced adhesive tape; The end of adjacent two light transmission piece is fixedly connected by the light transmission piece joint arbitrarily.
Each described outside portion that is used for the semiclosed cavity of mounting circuit boards also can be provided with one or more technology cavity.
The beneficial effects of the utility model are:
1, block without any structural member except light transmission piece the position near infrared emission tube on the housing assembly, and light transmission piece can reach more than 50% for ultrared transmitance, therefore preferably resolves the problem of housing component influences infrared light passage.
2, infrared posting light transmission piece fixed sturcture intensity is good, and appearance does not have screw, and whole structure is comparatively attractive in appearance, does not need to add in addition art designing's housing.
3, the cavity of housing assembly itself just has a baffle plate on circuit board top, does not need to add base plate again and just can well protect circuit board.
When 4, infrared posting light transmission piece fixed sturcture being safeguarded, only need unclamp trip bolt, just can carry out attended operation to the circuit board that needs are safeguarded, loaded down with trivial details when both having saved the circuit board of pasting with double faced adhesive tape that upholds one's heritage, need not break whole touch screen again, whole maintenance process is simple and convenient, satisfies the demand of producing infrared touch panel in batches easily.
