Utility model content the purpose of this utility model is to provide a kind of mouse module structure, adopts the laser-bounce principle, improves the analytical capabilities of the accurate positioning and the detecting of mouse.

In order to achieve the above object, the utility model has adopted following technical scheme, design a kind of mouse module structure, be positioned at the inside of on, comprise circuit board mainboard 2, sensing module 3 and luminescence component 5, sensing module 3 is positioned at circuit board mainboard 2 tops, sensor chip 14 is housed on the sensing module 3, this modular structure also has a L-shaped lens combination 4, lens combination 4 is made of middle hollow lens 6 that tilts and the base 8 that has cavity 7, sensing module 3 also is positioned at the top of the base 8 of cavity 7, luminescence component 5 is positioned at face on the convex lens 9 of lens 6 below, the central lines of the normal of convex lens 9 and lens 6 fixedly is equipped with convex lens 10 on the skew wall of cavity 7 inboards, the reflection direction of laser on surface level of the ejaculation of the normal direction of convex lens 10 and convex lens 9 coincides.

Principle of the present utility model: sensing module 3 is used for controlling the operation of slide-mouse, luminescence component 5 is in order to produce laser beam, sensor chip 14 is used for detecting the light that luminescence component 5 is sent, pack into the middle hollow lens 6 of inclination of lens combination 4 of luminescence component 5, the light that produces penetrates behind convex lens 9 optically focused of below, arrive the desktop that mouse uses, produce the hot spot point reflection that interference fringe forms, because " the ejaculation light reflection direction on the table of the normal direction of convex lens 10 and convex lens 9 coincides ", add upper bed-plate 8 and have cavity 7, this reflection ray will inevitably pass through convex lens 10, after amplifying, directly received by sensor chip 14, do not need through leaded light repeatedly promptly repeatedly reflection unit realize the light conduction.

Have resistance optical gate 11 on the top of base 8 of the present utility model and the convex lens 10 corresponding positions, resistance optical gate 11 has light hole 12 in convex lens 10 centers.Resistance optical gate 11 is the light tight optical gates of black, in order to stop those from the flare that convex lens 10 outers are passed, avoids sensor chip 14 wrong identification.

The normal of convex lens 9,10 of the present utility model and horizontal angle are 55 ° ± 10 °, and this moment, light guide effect was best.

Compared with prior art, the utlity model has following tangible advantage: 1, simple in structure, spare part quantity is few, and does not have movable part, whole processing and easy to assembly; 2, technique effect is good: resolution can reach 1600CPI (being that mouse whenever moves mobile 1600 pixels on 1 inch corresponding display screen), the captured image frequency reaches 9600 per second 9600 frames of per second (being per second 9600 frames), and detection rate can reach 40ips (being that per second moves 40 inches).
