Detailed ways

The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

Referring to accompanying drawings 1 to 3, they are three-dimensional disassembled diagrams of a mouse with variable light source intensity according to the present invention. The casing of the variable light source intensity mouse in this embodiment is composed of an upper casing 1 and a bottom casing 2, and a circuit board 4, a light emitting unit and an optical lens assembly 5, a main control chip 7, a state recognition unit 6 and other components are arranged in the casing Both are integrated on the front and back of the circuit board 4 .

In the light-emitting unit and the optical lens assembly 5, the light-emitting unit is usually composed of light-emitting diodes, which are generally red (and some are blue), and are bright (in order to obtain sufficient illuminance). The light emitted by the light-emitting diode illuminates the operating surface 3 at the bottom of the mouse through the optical lens at the bottom of the mouse, and then part of the light reflected back from the operating surface 3 at the bottom of the photoelectric mouse is transmitted to an optical sensor (micro-imaging device) through the optical lens assembly device) for imaging. When the photoelectric mouse moves, its moving track will be recorded as a set of coherent images shot at high speed. Finally, a dedicated image analysis chip (DSP, digital microprocessor) inside the photoelectric mouse is used to analyze and process a series of images captured on the moving track, and to judge the position of the mouse by analyzing the changes in the position of feature points on these images. Move the direction and distance to complete the positioning of the cursor.

The state identification unit 6 is used to monitor the position state of the mouse in real time and send the state parameters to the main control chip 7. The main control chip 7 is responsible for coordinating the work of each component in the photoelectric mouse, and communicating with external circuits (bridging) and various Signal transmission and collection, so as to control the light-emitting state of the light-emitting unit after calculation. In this embodiment, the state identification unit includes a height detection chip and an angle detection chip, both of which belong to the category of gravity sensors, and complete the conversion from gravity changes to electrical signals according to the principle of the piezoelectric effect. The characteristic of crystal deformation caused by acceleration inside it, because this deformation will generate voltage, as long as the relationship between the generated voltage and the applied acceleration is calculated, the distance between the bottom surface of the mouse shell and the operating surface, the distance between the mouse shell and the mouse shell can be calculated. The state parameter output of the angle between the bottom surface and the operation surface.

As shown in accompanying drawings 1 and 4, the state recognition unit 6 monitors the position state of the mouse in real time and sends the state parameters to the main control chip 7; The unit dims momentarily or the direct light source goes out. The state parameter can be the distance data between the mouse and the contact surface. When the state parameter received by the main control chip is greater than or equal to the predetermined threshold H, the light emitting unit is controlled to dim instantly or the direct light source is extinguished. Of course, this state parameter can also be used for other data, such as the size of the angle selected by the mouse.

In another embodiment of the present invention, the state identification unit 6 includes a touch sensing module arranged on the bottom surface of the mouse housing, which is used to send a detection signal to the main control chip 7 when it is detected that the bottom surface of the mouse housing is separated from the operation surface, Control the lighting unit to dim instantly or the direct light source to go out.

In other embodiments of the present invention, the state recognition unit 6 monitors the focusing state of the optical lens assembly in real time, and sends a signal to the main control chip 7 when the optical lens assembly is out of focus; when the main control chip receives the out-of-focus state signal, the control The lighting unit dims momentarily or the direct light source goes out.

In addition, the monitoring sensitivity of the state recognition unit can be adjusted at any time according to the user's needs by setting a sensitivity adjusting component. Since the light intensity of the mouse can be automatically adjusted, the light intensity can be automatically reduced or extinguished, so that the user will not feel uncomfortable or unpleasant due to the glare of the mouse light, and the user's enjoyment of using the computer is increased.

The above embodiments are only to illustrate the technical concept and characteristics of the present invention. All equivalent changes or modifications are within the protection scope of the present invention.
