The invention discloses a hand-pinch type self-powered flashlight with multiple power generation modes, which comprises a shell and an internal cavity, and the shell is provided with a switch (1), a condenser lens (2) and a hand-pinch power generation handle (3); The inner cavity includes an LED lamp board (8), a circuit board (7), a gear and rack gear, a rechargeable battery, an electromagnetic conversion power generation device (9) and a piezoelectric power generator; the gear and rack gear includes A double-sided toothed rack (5), two speed change gears, and a return spring (12) drive the rack (5) to move by pinching the power generator handle (3), and the rack (5) drives the speed change gear Movement, the two speed change gears respectively play a role in the electromagnetic conversion power generation device and the piezoelectric power generation device to realize the conversion from mechanical energy to electric energy. The flashlight of the present invention has various charging modes such as electromagnetic conversion power generation device, piezoelectric power generation device and traditional mains power connection, and is easy to use, and the energy source is green and environment-friendly.
Description
technical field [0001] The invention relates to a hand-pinch type self-powered flashlight with multiple power generation modes. Background technique [0002] With the development of modern society and economy, people are under more and more pressure from work and study, and more and more people fall in love with outdoor activities as a way to reduce stress. A flashlight is an essential tool in outdoor activities. However, most flashlights only rely on battery power, and it is very easy to run out of power in an emergency. In addition, human beings in the 21st century are facing an unprecedented energy crisis, and the use of environmentally friendly and pollution-free green energy in daily life has become a fashionable pursuit of people. Then a flashlight that can be self-powered in a green and environmentally friendly way can solve these problems well. Therefore, we have invented a hand-pinch power generation flashlight that utilizes electromagnetic conversion and positiv...
