Problems solved by technology

However, since the rectifier circuit rectifies the primary input signal generated by the current generated by the hand generator at different speeds into a current signal within a certain range, its power generation is irregular, which may easily cause the output voltage of the output interface to be unstable and affect the normal charging of the mobile phone. Even cause the phone to burn out

Abstract

The invention discloses a hand-operated charging device, which comprises a hand-operated power generation mechanism, a rectification module, a voltage stabilization module, a battery module, a boosting module and an output interface, wherein the hand-operated power generation mechanism generates and outputs electric energy, the rectification module converts the electric energy into a first direct-current power supply, the voltage stabilization module coverts the first direct-current power supply into a second direct-current power supply, a charging path of the battery module is connected withthe second direct-current power supply and stores the electric energy, a discharging path of the battery module transmits charging voltage to the boosting module, and the boosting module boosts and converts the charging voltage to direct-current output voltage and transmits the direct-current output voltage to the output interface. The hand-operated charging device is provided with the battery module and the boosting module, not only can prevent the problem of unstable voltage caused by the direct charging of the voltage stabilization module on a charged product (such as a mobile phone), but also can convert the electric energy of the battery into high enough charging voltage to supply to the charged product through the boosting module, thereby ensuring the charging efficiency.

Description

technical field [0001] The invention relates to a charging device, in particular to a hand-operated charging device. Background technique [0002] Referring to Chinese patent CN 201520102913.4, the existing manual charging device generally includes a rectifier circuit and a voltage stabilizing circuit, and the voltage stabilizing circuit is directly connected to the battery of the mobile phone to charge the mobile phone. However, since the rectifier circuit rectifies the primary input signal generated by the current generated by the hand generator at different speeds into a current signal within a certain range, its power generation is irregular, which may easily cause the output voltage of the output interface to be unstable and affect the normal charging of the mobile phone. Even cause the phone to burn out. [0003] Therefore, there is an urgent need for a hand-operated charging device that can solve the above-mentioned problems. Contents of the invention [0004] The...
