Description

Integrated optical mouse lens

Technical field

The utility model relates to the optical mouse lens, especially refer to that a kind of light source portion of optical mouse and sensing cell of making is integrated in the wafer module, and cooperate this lens module to shorten the path that light source signal transmits, light source portion is launched, and the light source after the refraction is more concentrated, and can not produce the phenomenon of dissipation, make optical mouse have the integrated optical mouse lens of better use effect.

Background technology

The optical mouse of generally commonly using, it mainly is the sliding ball that replaces conventional mouse with optical technology, shown in Fig. 5,6, be the optical mouse of commonly using, this optical mouse mainly is made up of a upper shell (not shown), a lower shoe 6, a lens combination 60 and a circuit board 61; Plug a light emitting diode 62 (LED) and a sensor 63 (Sensor) on the precalculated position of this circuit board 61, and the bottom of this light emitting diode 62 (LED) and sensor 63 (Sensor) is connected in the lens combination 60 on the lower shoe 6; During use, the light signal that this light emitting diode 62 is sent refracts to desktop 7 through first lens 601, the catoptron 603 of this lens combination 60, reflex to second lens 602 of lens combination 60 again through desktop 7, and sensed device 63 receives.

Yet, the above-mentioned optical mouse of commonly using, it must be respectively at light emitting diode 62, sensor 63 are set on the circuit board 61, and the Position Design that will cooperate light emitting diode 62, sensor 63 and lower shoe 6 is made this lens combination 60, not only need to get the raw materials ready respectively, be provided with, bother, and cost is higher, these members that the position is set is also quite important, must make the opticpath and the effect thereof of its refraction, reflection meet desired accuracy, thereby become difficult point in the design, above-mentioned many restrictions cause optical mouse general mouse on promoting and popularizing inferior.

Moreover, for cooperating light emitting diode 62 (LED) and the sensor 63 (Sensor) on this optical mouse, it needs project organization complicated lens group 60, just can make light that light emitting diode 62 sends through first lens 601, catoptron 603 refracts to desktop 7, reflex to second lens 602 of lens combination 60 again through desktop 7, and sensed device 63 receives, and the light refraction of light emitting diode 62 is longer to the path of sensor 63, the light that causes light emitting diode 62 to launch, and the light after the refraction is concentrated inadequately, must produce the phenomenon of dissipation, so, the member of generally commonly using optical mouse is numerous and diverse, and the production cost height, can not satisfy user's demand.

Summary of the invention

Fundamental purpose of the present utility model, be to provide a kind of light source portion of optical mouse and sensing cell of making to be integrated in the wafer module, and the fit lens module shortens the path that the light signal transmits, the light that light source portion is launched, and the light after the refraction is more concentrated, and can not produce the dissipation phenomenon, makes optical mouse have the integrated optical mouse lens of better use effect.

For reaching above-mentioned purpose, integrated optical mouse lens of the present utility model, it comprises: the housing that is combined by a loam cake and a lower cover, and following the covering of this housing offer a through hole, and the through hole place winding of this lower cover has a lens module; One is fixedly arranged on the circuit board in the above-mentioned housing, offer a corresponding aperture corresponding with this through hole on this circuit board, and the corresponding aperture place winding of this circuit board has a wafer module; It is characterized in that:

This lens module comprises a base, has a supporting part on this base, has first lens and second lens on this supporting part, and is provided with a reflecting part in the side adjacent to second lens, and the end face of this reflecting part is connected in the bottom of first lens;

In addition, have a light source portion on this wafer module, and a side of adjacent light source portion is provided with a sensing cell, this light source portion is corresponding with first lens, and this sensing cell is corresponding with second lens.

Because the utility model can make the light source portion of optical mouse and sensing cell be integrated in the wafer module, and match with this lens module, so can shorten the transfer path of light signal, the light that light source portion is launched, and the light after the refraction is more concentrated, and can not produce the phenomenon of dissipation, and make optical mouse have better use effect.
