A protection structure of an electric derailleur comprises a driving part and a transmission part. The driving part is connected to a frame, the driving part comprises a driving part and a driving shaft, and the driving part drives the driving shaft to rotate; the transmission part comprises a first transmission part, a second transmission part and an elastic part, in a first state, the driving part drives the driving shaft to rotate to drive the first transmission part to rotate, and the first transmission part drives the second transmission part to rotate to drive a derailleur frame to move;and in a second state, the second transmission part is stressed to generate sliding friction with the first transmission part, and the second transmission part and the first transmission part providea buffering effect to prevent the transmission part from being damaged due to a direct impact.
一种电动拨链器的保护结构,包含有一驱动部及一传动部,该驱动部连接至一车架,该驱动部包含一驱动件及一驱动轴,该驱动件驱动该驱动轴转动;该传动部包含一第一传动件、一第二传动件及一弹性件,于一第一状态下,该驱动件驱动该驱动轴转动而带动该第一传动件转动,且该第一传动件带动该第二传动件转动,以带动该拨链架移动;于一第二状态下,该第二传动件受力而与该第一传动件产生滑动摩擦,该第二传动件与该第一传动件提供一缓冲效果,以避免传动件直接受到冲击而损坏。
