Abstract

An electric power assisting device comprises a drive piece, a main gear, transmission assemblies and friction wheels. The main gear is connected with the drive piece and can rotate in the first direction. The transmission assemblies comprise a first transmission gear and a second transmission gear. The first transmission gear comprises a transmission shaft, a first tapered tooth part and a second tapered tooth part, wherein the transmission shaft is sleeved with the first tapered tooth part and the second tapered tooth part in a spaced manner and extends in the second direction perpendicular to the first direction. The first tapered tooth part is engaged with the main gear. The second transmission gear comprises a rotary shaft and a third tapered tooth part arranged on the rotary shaft in a sleeving manner. The rotary shat extends in the first direction. The third tapered tooth part is engaged with the second tapered tooth part. The friction wheels are connected with the rotary shaft, spaced from the third tapered tooth part and used for abutting against a tire of a bicycle. The electric power assisting device is convenient to install.

Description

technical field [0001] The invention relates to an electric booster installed on a bicycle. Background technique [0002] Its electric booster of bicycle of prior art usually adopts wheel hub motor. However, when the hub motor is installed, the bicycle usually needs to be disassembled, and even the structure of the bicycle needs to be changed to match the installation, so the installation is relatively difficult. Contents of the invention [0003] In view of the above, it is necessary to provide an electric power booster that is easy to install. [0004] The invention also provides a bicycle using the electric power assist device. [0005] An electric power booster, which includes a driving member, a main gear, a first transmission assembly and a first friction wheel, the main gear is connected to the driving member and can rotate around a first direction, and the first transmission assembly includes sequentially connected first A transmission gear and a second transmis...
