Abstract
An anti-light infrared touch frame comprises a shell, a circuit board and an LED (light-emitting diode) lamp. The shell is provided with a cavity for holding the circuit board and the LED lamp, the LED lamp is electrically connected with the circuit board, and the right upper side of the LED lamp inside the shell is serrated. By the aid of the scheme, external light is diffused in all directions by a serrated structure, the external light received by the infrared touch frame is decreased, and the light interference resistance of the infrared touch frame is improved.
Description
Technical field
The utility model relates to a kind of touch frame, particularly relates to a kind of anti-smooth infrared touch frame.
Background technology
Along with the development of technology, people more and more use touch technology, and the infrared touch frame, with the Stability and adaptability of its height, is widely used in every field, for example: ATM, game machine, industry control, self-help inquiry apparatus, POS machine, song-order machine.Electronic whiteboard etc.
As shown in Figure 1, housing is rectilinear form near the part of LED fluorescent tube upper right side (16) to infrared touch frame of the prior art, and extraneous light when penetrating, has a great impact the LED lamp luminescence of infrared touch frame.
The utility model content
Based on this, be necessary for the problems referred to above, a kind of anti-smooth infrared touch frame is provided.
A kind of anti-smooth infrared touch frame, comprise housing, circuit board and LED lamp, described housing has the cavity of the described circuit board of a placement and described LED lamp, and described LED lamp and described circuit board are electrically connected, and wherein said housing inboard is zigzag in described LED lamp upper right side.
Above-mentioned anti-smooth infrared touch frame, engrail is done in the part of LED fluorescent tube upper right side in the housing inboard, diffuse reflection occurring when can make the ambient light line inject, greatly reduced the extraneous light that the infrared touch frame receives, has improved the anti-smooth interference performance of infrared touch frame.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of infrared touch frame in prior art;
Fig. 2 is structural representation of the present utility model.
Embodiment
Embodiment below in conjunction with accompanying drawing to the anti-smooth infrared touch frame of the utility model is described in detail.
As shown in Figure 2, the structural representation that Fig. 2 is the anti-smooth infrared touch frame of the utility model, comprise housing 10, circuit board 20 and LED lamp 30, described housing 10 has the cavity 11 of the described circuit board 20 of a placement and described LED lamp 30, described LED lamp 30 is electrically connected with described circuit board 20, described housing inboard is zigzag in described LED lamp upper right side 16, can make ambient light line generation diffuse reflection.
Described LED lamp 30 comprises lamp holder 31 and pin 32, and side by side and support described circuit board 20, described pin 32 ends insert and are welded on circuit board 20 for described lamp holder 31 and described circuit board 20.
Described housing 10 inboards are provided with the first protuberance 12 in LED lamp 30 places, the surface of described the first protuberance 12 conflict LED lamps 30.
Described housing 10 inboards are provided with the second protuberance 13, the end of described the second protuberance 13 conflict circuit boards 20 in the top of the first protuberance 12.Described the second protuberance 13 and the common fixing circuit board 20 of lamp holder 31.
Described housing 10 1 sides are provided with the 3rd protuberance 14, described the 3rd protuberance 14 support circuit plates 20.By the 3rd protuberance 14 and the common also fixing circuit board 20 that supports of pin 32.
Described housing 10 inboards are provided with the 4th protuberance 15, the end of described the 4th protuberance 15 conflict circuit boards 20 in the top of the 3rd protuberance 14.The also end of fixing circuit board 20 is clamped in described the 4th protuberance 15 and the 3rd protuberance 14 actings in conjunction.
Above-mentioned anti-smooth infrared touch frame, 16 places, LED lamp upper right side are zigzag, can make ambient light line generation diffuse reflection, when extraneous light is injected the infrared touch frame, most light is reflected, only have the light of fraction to enter the infrared touch frame, greatly reduce the impact luminous on LED lamp 30, improved the anti-smooth interference performance of infrared touch frame.
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.
