Abstract
The invention relates to a notebook computer with a hand-cranked power generation function, comprising a hand-cranked power generator and a common notebook computer. The notebook computer is powered by hand-cranked power generation through the circuit connection of the hand-cranked power generator, an AC-DC (Alternating Current-Direct Current) booster circuit, a power switching circuit, a power control circuit of the notebook computer, a converter IC (Integrated Chip) circuit, an overvoltage protection circuit, and a current sampling and feedback circuit. The invention solves the power supply problem of the notebook computer under the conditions of external power supply shortage and battery charge depletion.
Description
Technical field
The present invention relates to a kind of notebook computer with the hand-rail type electricity generate function.
Background technology
The advantage of notebook computer is to make things convenient for the user to carry, this is that it is subjected to the reason that the user extensively welcomes, but, do not having under the situation of power supply, the battery of the notebook computer several hrs of can only powering, as run into battery electric quantity and exhaust and do not have under the external power supply situation, the user can't use notebook computer, if there is not back-up source, this brings many inconvenience to the user.Therefore, solving the powerup issue of notebook computer under the situation that does not have external power supply and battery electric quantity to exhaust is very important.
Summary of the invention
