The invention discloses a portable bicycle electric booster which comprises a shell assembly, a mounting assembly, a driving assembly and an adjusting assembly. The shell assembly comprises a shell for mounting each assembly and a shell cover detachably mounted on the side wall of the shell; the mounting assembly comprises a clamping seat movably mounted above the shell, movable shafts are arranged on the two sides of the clamping seat, the clamping seat is movably mounted above the shell through the movable shafts, and a tilt angle sensor is fixedly mounted on the outer wall of one side of the clamping seat; the driving assembly comprises a driving wheel movably installed on the lower portion of the inner side of the shell. Opening and closing of gear sets of different models can be automatically adjusted according to the gradient when a vehicle is ridden, so that the automatic speed changing function is achieved, stronger torque can be provided during uphill, efficient stability of assistance during uphill is guaranteed, output torque and speed can be adjusted through the speed changing function under the condition that voltage does not need to be changed, and the speed changing effect is good. Therefore, electric energy can be effectively saved, and endurance is increased.

    本发明公开了便携式自行车电助力器,包括外壳组件、安装组件、驱动组件和调节组件;所述外壳组件包括可供各组件安装的壳体以及壳体侧壁可拆卸安装的壳盖;所述安装组件包括活动安装于壳体上方的夹持座,所述夹持座两侧设有活动轴,所述夹持座通过活动轴活动安装于壳体上方,所述夹持座一侧外壁固定安装有倾角传感器;所述驱动组件包括活动安装于壳体内侧下方的驱动轮。本发明可以根据车辆骑行时的坡度大小自动调节不同型号齿轮组的开合,从而实现自动变速功能,可在上坡时提供更为强劲的扭矩,确保上坡时的助力高效稳定性,且通过变速功能可在无需改变电压的情况下进行输出扭矩和速度的调整,因此可有效解决电能,增加续航。
