Abstract
The utility model discloses an optical mouse lens which mainly comprises a shell composed of an upper cover and a lower cover; a circuit board is fixed in the shell; a light source and a wafer module group are arranged on the circuit board; a through hole is arranged on the circuit board; a through hole is arranged on the lower cover of the shell and is connected with a lens module group; the lens module group is connected with the circuit board through the through hole of the circuit board. The optical mouse lens is characterized in that the lens module group comprises a base; a support part is arranged on the upper part of the base; a first lens and a second lens are arranged on one surface of the support part; a first reflective part and a second reflective part are arranged on the other surface of the support part in opposite to the surface where the first lens and the second lens are arranged; the first and the second reflective parts are corresponding to the first lens and the second lens through a certain angle. Based on the structure, the light beam emitted by the light source and the refracted light beam become more concentrated so that the positioning of the optical mouse becomes more accurate and the cursor becomes more sensitive.
Description
Technical field
The utility model relates to the optical mouse lens, and light source portion is launched, and the light source after the refraction is more concentrated, and can not produce the phenomenon of dissipation, makes optical mouse have the optical mouse lens of better use effect.
Background technology
The optical mouse of generally commonly using mainly is the sliding ball that replaces conventional mouse with optical technology, is the optical mouse of commonly using as Fig. 4,5, and 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 15 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 is set on the circuit board 61, sensor 63, and to cooperate light emitting diode 62, the Position Design of sensor 63 and lower shoe 6 is made this lens combination 60, these members 20 that the position is set is also quite important, must make its refraction, the opticpath and the effect thereof of reflection meet desired accuracy, thereby become difficult point in the design, 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 emitting diode 62 send 25 light through first lens 601, catoptron 6 still 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, cause sensor 63 (sensor) ligh-induced effect poor, it is not accurate generally to commonly use the optical mouse location, cursor is insensitive, can not satisfy user's demand.
The utility model content
The purpose of this utility model is the light that the lens module is launched light source portion, and the light after the refraction is more concentrated, and can not produce the dissipation phenomenon, and it is more accurate to make optical mouse demarcate the position, cursor is sensitive more, the optical mouse lens with better use effect.
In order to achieve the above object, the technical scheme that the utility model adopted is: a kind of optical mouse lens, it mainly comprises: the housing that is combined by loam cake, lower cover, one circuit board is fixedly arranged in the above-mentioned housing, this circuit board is provided with a light emitting source and wafer module, and a through hole is arranged on this circuit board; Following covering at above-mentioned housing is provided with a through hole, this through hole connects a lens module, this lens module is connected with circuit board by the through hole that the foregoing circuit plate is provided with, it is characterized in that: this lens module comprises a base, base is provided with a supporting part, its one side of this supporting part is provided with first lens and second lens, be provided with first reflection part and second reflection part with first lens and the second lens opposing face on supporting part, first reflection part is corresponding with first lens and second lens by special angle with second reflection part.
Described light emitting source is the LED luminophor.
Described lens are convex lens.
The position of through hole is located between light emitting source and the wafer module on the described circuit board.
After adopting said structure, match the light that light source portion is launched with this lens module during use, and the light after the refraction is more concentrated, and can not produce the phenomenon of dissipation, and it is more accurate to make optical mouse demarcate the position, cursor is sensitive more, the optical mouse lens with better use effect.
