The invention discloses a windward power assisting device for a bicycle. The windward power assisting device is characterized in that two fixing devices which are symmetrical front and back are arranged on the right side of a power assisting machine body, the power assisting machine body is fixedly connected to a bicycle rear leaning frame through the fixing devices, the right side of the interiorof the power assisting machine body is provided with two air inlets which are provided with rightward openings and are symmetrical up and down in a communicating mode, a fan cavity is formed in the left sides of the air inlets in a communicating mode, a fan rotating shaft connected to the left wall of the fan cavity in a rotating mode is arranged in the fan cavity, and a fan rotor is fixedly connected to the axis of the right end face of the fan rotating shaft. According to the windward power assisting device, relative wind power generated when the bicycle runs serves as power and is converted into mechanical energy firstly, the mechanical energy meets the energy conversion condition through acceleration of an acceleration box and then is converted into electric energy to be stored, meanwhile, the device can detect the running state of the bicycle and provide assistance power for a rear wheel of the bicycle during windward running so that a driver can save more effort in the driving process.
本发明公开的一种用于自行车的迎风助力装置,所述助力机身右侧设有前后对称的两个固定装置,所述助力机身通过所述固定装置固定连接于自行车后依架,所述助力机身内右侧连通设有开口向右且上下对称的两个进风口,所述进风口左侧连通设有风扇腔,所述风扇腔内设有转动连接于所述风扇腔左壁的风扇转轴,所述风扇转轴右端面轴心固定连接有风扇转子,本发明通过自行车行驶时产生的相对风力作为动力,先将其转换为机械能,经过加速箱加速使其满足能量转化条件,再将其转变为电能并储存,同时本装置能检测自行车的行驶状态,在迎风行驶时对自行车后轮提供助力,使驾驶员行驶过程中更加省力。
