The invention discloses a quickly-assembled power-assisted steering electric controller for a vehicle, which comprises a PCB (Printed Circuit Board), a base and a cover board, wherein a conical support column and a heat conducting seat in a right trapezoid shape are integrally formed on the base; the PCB is arranged on the conical support column, is positioned through two positioning columns penetrating through the PCB, and is then fixed on the heat conducting seat by combining with screws; the base and the cover board are pressed together; the conical support column is positioned in the cover board and enables the cover board and the base to be fastened tighter and tighter; the position, close to a right back corner, of the top of the cover board is provided with a triangular anti-misloading mark; and the back side of the base is provided with a plurality of strip-shaped heat conducting slots extending left and right. The controller disclosed by the invention effectively avoids the problem of unfirm connection between the base and the cover board as well as between the PCB and the base after installation and effectively avoids the problem of overhigh local temperature of the PCB, prevents the cover board from being installed in an inverted way, and realizes assembly once.
