The embodiment of the invention discloses an electronic derailleur for a bicycle and a variable-speed bicycle. The electronic derailleur comprises a base component, a P joint component, a chain guide component and a power source, and the P joint component is connected with the base component through a hinged quadrilateral component; wherein the hinged quadrilateral component comprises an inner connecting rod, an outer connecting rod and an electric driving part, the driving axis of the electric driving part coincides with a target diagonal line of a hinged quadrilateral, and the electric driving part is used for changing the length of the target diagonal line, so that the hinged quadrilateral is deformed; the power source is detachably connected to the P joint component and electrically connected with the electric driving piece through a power line. According to the electronic derailleur, the distance between the power source and the electric driving part can be shortened, the power line can be connected with the power source in the shortest connection mode, the problem of complex wiring is avoided, and therefore the structural compactness of the electronic derailleur is improved.
本发明实施例公开了一种自行车用电子拨链器及变速自行车,所述电子拨链器包括基座构件、P关节构件、链条导向构件和电源,所述P关节构件通过铰接四边形构件与所述基座构件连接;其中,所述铰接四边形构件包括内连杆、外连杆和电驱动件,其中,所述电驱动件的驱动轴线与铰接四边形的目标对角线重合,用于改变所述目标对角线长度,从而使所述铰接四边形变形;所述电源可拆卸连接于所述P关节构件上,所述电源通过电源线与所述电驱动件电性连接。本发明实施例实现能够缩短电源和电驱动件之间的距离,使得电源线能够以最短的连接方式和电源连接,避免了走线复杂的问题,从而提高了电子拨链器的结构紧凑性。
