Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric mouse, in particular to a double-light path mouse lens and a mouse thereof. Background Art

[0002] An optical mouse is a hardware device that detects the displacement of the mouse through infrared or laser, converts the displacement signal into an electrical pulse signal, and then controls the movement of the cursor arrow on the screen through program processing and conversion.

[0003] The current optical mouse only uses one LED lamp as a light source, such as a mouse lens and a mouse disclosed in the Chinese utility model patent with publication number CN219302994U, which has the following disadvantages:

[0004] 1. When an LED light shines on the desktop, only one angle of the light beam can be received by the mouse IC. Since the mouse IC receives different light beam angles for desktops with different roughness, brightness and texture, this will lead to obvious differences in the positioning accuracy of the mouse IC.

[0005] 2. Using only one LED light as the light source will cause the mouse IC to have a fixed focal length. Since the height of the mouse bottom shell varies from manufacturer to manufacturer, the distance between the mouse IC chip and the desktop will be different, which will cause unclear scanning of the desktop, resulting in different interface effects, such as line folding, cursor jitter, cursor stagnation, and inaccurate clicks.

[0006] 3. The mouse IC needs to constantly adjust the power consumption to adapt to the changes in desktop color, which will cause the power consumption of the mouse IC to increase. Utility Model Content

[0007] The utility model aims to provide a dual-light path mouse lens and a mouse thereof, so as to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above-mentioned purpose, on the one hand, the utility model provides the following technical solutions: a dual-light path mouse lens and a mouse thereof, comprising a frame, and a light input lens and a light output lens arranged in the frame and distributed front to back, the light input lens and the light output lens being integrally formed, the upper end of the light input lens being integrally formed with a first light-focusing arc surface, the upper end of the light input lens and being located at the rear side of the first light-focusing arc surface being integrally formed with a second light-focusing arc surface, the lower end of the light input lens and being located directly below the first light-focusing arc surface being integrally formed with a reflective polished surface, the lower end of the light input lens and being located directly below the second light-focusing arc surface being integrally formed with a third light-focusing arc surface, and the lower end of the light input lens and being located between the reflective polished surface and the third light-focusing arc surface being integrally formed with a refractive polished surface;

[0009] A first refractive arc surface is integrally formed at the upper end of the light output lens, and a second refractive arc surface is integrally formed at the lower end of the light output lens and directly below the first refractive arc surface;

[0010] A first LED light source and a second LED light source are disposed above the frame. The first LED light source is located directly above the first light-focusing arc surface, and the second LED light source is located directly above the second light-focusing arc surface.

[0011] Optionally, the first light-focusing arc surface and the second light-focusing arc surface are both upward convex arc-shaped polished surfaces.

[0012] Optionally, the reflective polishing surface is a polishing plane inclined backward, and the refractive polishing surface is a polishing plane inclined forward.

[0013] Optionally, the first refractive arc surface is an upwardly convex arc-shaped polished surface, and the second light-focusing arc surface is an upwardly convex arc-shaped polished surface.

In addition, the mouse IC does not need to continuously adjust power consumption to adapt to changes in desktop color.

[0023] Example: See Figures 1 to 3 The utility model provides a dual-light path mouse lens, comprising a frame 1, and a light-incoming lens 2 and a light-outgoing lens 3 arranged in the frame 1 and distributed front and back, wherein the light-incoming lens 2 and the light-outgoing lens 3 are integrally formed. A first light-focusing arc surface 4 is integrally formed at the upper end of the light-incoming lens 2, and a second light-focusing arc surface 5 is integrally formed at the upper end of the light-incoming lens 2 and located at the rear side of the first light-focusing arc surface 4, and both the first light-focusing arc surface 4 and the second light-focusing arc surface 5 are upwardly convex arc-shaped polished surfaces.

[0024] A reflective polished surface 6 is integrally formed at the lower end of the light incident lens 2 and located directly below the first focusing arc surface 4. A third focusing arc surface 8 is integrally formed at the lower end of the light incident lens 2 and located directly below the second focusing arc surface 5. A refractive polished surface 7 is integrally formed at the lower end of the light incident lens 2 and located between the reflective polished surface 6 and the third focusing arc surface 8. The reflective polished surface 6 is a polished plane inclined backward, and the refractive polished surface 7 is a polished plane inclined forward.

[0025] A first refractive arc surface 9 is integrally formed at the upper end of the light output lens 3, and a second refractive arc surface 10 is integrally formed at the lower end of the light output lens 3 and directly below the first refractive arc surface. The first refractive arc surface 9 is an upward convex arc polished surface, and the second focusing arc surface 5 is a top-bottom convex arc polished surface.

[0026] A first LED light source 11 and a second LED light source 12 are provided above the frame 1 . The first LED light source 11 is located directly above the first light-focusing arc surface 4 , and the second LED light source 12 is located directly above the second light-focusing arc surface 5 .

[0027] The utility model also provides a mouse, comprising the above-mentioned dual-light path mouse lens, a circuit board 13, and a mouse IC 14 integrated on the lower surface of the circuit board 13. The first LED light source 11 and the second LED light source 12 are integrated on the lower surface of the circuit board 13, and the mouse IC 14 is located directly above the first refractive arc surface 9.

[0028] like Figure 3 As shown, the light emitted by the first LED light source 11 is first focused by the first focusing arc surface 4 and then enters the light incident lens 2, and then is reflected by the reflective polished surface 6 and then emitted from the refractive polished surface 7 and emitted to the desktop 15, and then is reflected by the desktop 15 and then enters the light output lens 3 through the second refractive arc surface 10, and then is emitted through the first refractive arc surface 9, and finally is received by the mouse IC14.

[0029] Similarly, the light emitted by the second LED light source is first focused by the second focusing arc surface 5 and then enters the light incident lens 2, and then is refracted by the third focusing arc surface 8 and emitted toward the desktop 15, and then is reflected by the desktop 15 and enters the light output lens 3 through the second refractive arc surface 10, and then is emitted through the first refractive arc surface 9, and finally is received by the mouse IC14.

[0030] The utility model uses the light input lens 2, the first LED light source 11 and the second LED light source 12 to allow the mouse IC 14 to receive the light beams reflected from the desktop from two angles, thereby avoiding obvious differences in the positioning accuracy of the mouse IC 14 on desktops of different textures, brightness, and roughness, and solves the problem that the scanning effect of the mouse IC 14 is affected by the different heights of the mouse bottom shell. In addition, the mouse IC does not need to constantly adjust the power consumption to adapt to the changes in the color of the desktop. The light intensity provided by the first LED light source 11 and the second LED light source 12 is greater than the light intensity of a single LED light source, which can bring lower energy consumption and better performance to the mouse IC 14.
