A method for obtaining pressure-sensitive feedback for luminous flux changes on a single optical component

Abstract

The invention discloses a method for obtaining pressure-sensitive feedback on a single optical component to realize luminous flux change. When the button is pressed, the dimming area of ​​the dimming board gradually decreases, and the dimming area S4 of the dimming area changes, corresponding to the dimming area S4 of the dimming area. The light emitted by the light plate through the light-emitting element changes, and the luminous flux Φ at this time also changes correspondingly. Due to the movement of the dimming area, the luminous flux Φ obtained by the light-receiving element changes; and then the real-time pressing position is obtained by calculating the changed luminous flux Φ H, through the real-time position H, the pressed gravity and the pressed position can be calculated, and then any level of pressure-sensitive feedback can be obtained. This application only needs a single optical component to obtain the pressed gravity and pressed position, realize any level of pressure-sensitive feedback, and then realize the corresponding pressure-sensitive operation through simulation; the structure adopted by the method of this application is convenient to install and assemble, and the production cost Low, when in use, the feedback obtained by pressing is timely and sensitive, the service life is long, and it is not easy to wear.

Description

technical field [0001] The invention relates to the field of potential switches, in particular to a method for achieving pressure-sensitive feedback for realizing luminous flux changes on a single optical component. Background technique [0002] The existing potential switch can only obtain two kinds of signals by blocking or not blocking the light receiver by the baffle, and cannot obtain the signal during the pressing process; at the same time, due to the small area of ​​the CCD, the height of the CCD is much smaller than the movement distance of the baffle , The light receiver is blocked when the baffle is displaced for a short distance during the pressing process, and accurate pressing speed and pressing position cannot be obtained. So someone came up with the idea of ​​setting up multiple optical receivers to obtain the signal during the pressing process, but such signals are intermittent and discontinuous, and the cost of adding optical receivers is high, and it is dif...

Problems solved by technology

[0002] The existing potential switch can only obtain two kinds of signals by blocking or not blocking the light receiver by the baffle, and cannot obtain the signal during the pressing process; at the same time, due to the small area of ​​the CCD, the height of the CCD is much smaller than the movement distance of the baffle , the baffle shifts a short distance during the pressing process to block the light receiver, making it impossible to obtain accurate pressing speed and pressing position

So someone came up with the idea of ​​setting up multiple optical receivers to obtain the signal during the pressing process, but the interruption of such signals is discontinuous, and the cost of adding optical receivers is high, and it is difficult to arrange and install multiple optical receivers in sequence
