1. A removable battery fixing assembly of an electric vehicle, comprising:

  • a removable battery module comprising;

    a main body having a first side surface and a second side surface, wherein the first side surface and the second side surface is located adjacent to each other, and at least one guiding bar is disposed on the first side surface; and

    a fixing device installed in a vehicle body of an electric vehicle and comprising;

    a base;

    a driving part disposed on the base;

    a main transmission part connected with the driving part;

    a guiding part disposed on the base;

    a first stopping part pivotally coupled with the main transmission part; and

    a second stopping part pivotally coupled with the main transmission part through plural connection elements,wherein for installing the removable battery module in the vehicle body of the electric vehicle, the at least one guiding bar on the first side surface of the removable battery module is aligned with the guiding part and moved along the guiding part, wherein when the removable battery module is moved to a specified position, the main transmission part is driven by the driving part to be moved horizontally, so that the first stopping part is correspondingly rotated to urge against an end part of the guiding bar, wherein when the removable battery module is moved to the specified position, the second stopping part is correspondingly driven by the plural connection elements to lock the second side surface of the removable battery module, wherein the main transmission part further comprises a guiding slot, and the main transmission part is coupled with the base by penetrating a fixing pin through the guiding slot, wherein a reciprocating moving distance of the main transmission part is limited by a first end and a second end of the guiding slot and a locking status and an unlocking status of the fixing device are defined according to a position of the fixing pin relative to the first end and the second end of the guiding slot, and when the fixing device is in the unlocking status, the first stopping part is inclined with respect to the main transmission part, wherein when the main transmission part is driven by the driving part to be moved horizontally and the fixing device is in the locking status, the first stopping part is rotated and upraised to urge against the end part of the guiding bar on the first side surface of the removable battery module, so that the removable battery module is locked by the first stopping part.
