Bicycle carrying spare charging device

The invention provides a bicycle carrying a spare charging device, the bicycle includes a bicycle body, self-generator, power storage device and voltage-adjustable charger, electric energy generated by the rear-wheel driven self-generator is sent to the power storage device for storage during riding, and the voltage of the voltage-adjustable charger is switched to be consistent with the voltage ofthe equipment that needs charging, so that charging can be realized. The invention overcomes the problem that electric appliances such as a mobile phone and digital equipment cannot be charged duringthe original bicycle riding. The invention has the characteristics of simple and compact structure, capability of charging the mobile phone and the digital equipment during riding, and convenient operation. 本发明提供的种携带备用充电装置的自行车，它包括自行车本体、自发电机、蓄电装置和电压可调充电器，通过骑行时后轮驱动自发电机产生电能输送至蓄电装置被存储，通过切换电压可调充电器的电压与所需充电设备电压致即可实现充电。克服了原自行车骑行时中途不可对手机、数码设备类电器进行充电的问题。本发明具有结构简单紧凑，骑行中途可对手机和数码设备进行充电，操作方便的特点。
