Abstract
The invention discloses a dustproof and waterproof frame of an infrared touch screen, and the frame provided by the invention comprises an upper shell, a lower shell and a light filtering stripe or light refection stripe, wherein one side of the upper shell is in tight snap-in connection with one side of the lower shell by virtue of a convex buckle and a concave buckle, an convex buckle at the other side of the upper shell is in tight snap-in connection with a concave buckle at the upper end of the light filtering strip or light refection strip, and the lower end of the light filtering strip or light refection strip is bonded with the other side of the lower shell through waterproof glue; and the upper shell, the lower shell and the light filtering strip or light refection strip are connected into a waterproof closed frame body, and a PCB (printed circuit board) and an LED (light emitting diode) lamp are arranged in the cavity of the frame body. The light filtering strip or light refection strip is connected with the upper shell and the lower shell so as to form a seamless waterproof inclined plane (with a gradient of 60-90 degrees) which can prevent water and dust from entering in the touch screen, and protect infrared touch components in the touch screen and prolong the service life of a product. The frame disclosed by the invention is simple and compact in structure and convenient to install, and can achieve the effect of water and dust prevention by using less objects.
Description
Technical field
The present invention relates to the frame field of infrared touch panel, relate in particular to a kind of frame of dustproof and waterproof infrared touch panel.
Background technology
The border structure complexity of traditional infrared touch panel, size are big, and thickness is big, connects by screw between upper casing and the lower casing, there is the slit, and in the middle of optical filtering bar one side, have the connection slit, and cause dust to fall into the frame the inside by being connected the slit easily with water, influence circuit component work.
Summary of the invention
The object of the invention provides a kind of frame of ultra-thin super narrow and dustproof and waterproof infrared touch panel, is convenient to installation and removal.
The frame of a kind of dustproof and waterproof infrared touch panel provided by the invention, comprise upper casing, lower casing and optical filtering bar or reflecting strips, one side of described upper casing and a side of lower casing are by protruding button and the close engagement connection of recessed fastening, the close engagement connection of recessed fastening of the protruding button of the opposite side of described upper casing and optical filtering bar or reflecting strips upper end, described optical filtering bar or reflecting strips lower end bond together by marine glue and lower casing opposite side; Described upper casing, lower casing, optical filtering bar or reflecting strips connect into the closed framework of a waterproof, are provided with PCB circuit board and LED lamp in the framework cavity.
Concrete, the close engagement connection of the first recessed fastening of first a protruding button of a side of described upper casing and a side of lower casing, the close engagement connection of recessed fastening of second protruding button of the opposite side of described upper casing and optical filtering bar or reflecting strips upper end.
Further, described optical filtering bar or reflecting strips are connected with upper casing, lower casing coupling, and forming a degree of tilt at described frame side is the seamless waterproof inclined-planes of 60 ~ 90 degree.
Further, the inboard middle of described optical filtering bar or reflecting strips has a recess, is used for the recess with the inboard teat formation of upper casing and lower casing, and described PCB circuit board level is blocked, and keeps Stability Analysis of Structures.
Further, described upper casing and lower casing are plastics or the one-shot forming of aluminium alloy pressing mold, are installed in the edge of infrared touch panel.
The frame of dustproof and waterproof infrared touch panel of the present invention; by protruding button and recessed button engagement connection; it is the seamless waterproof inclined-planes of 60 ~ 90 degree that described optical filtering bar one side forms a degree of tilt; there is the shortcoming that connects the slit in the middle of having avoided in the prior art; this structure can block water, dust enters touch-screen inside, infrared touch assembly that can the better protect the inside and prolong product serviceable life.Described border structure is simple, compactness, thin thickness, need to accomplish having only 0.5 ~ 1.5CM height according to design, and convenient the installation, upper casing, lower casing, optical filtering bar or reflecting strips are directly pushed to promptly upper latch notch and have been installed, utilize less object just can realize the function of water proof and dust proof, low cost of manufacture.
