The invention discloses an electric control box component special for power-assisted steering. The electric control box component comprises a PCB, a base and a cover plate. Tapered support columns and a right-angle trapezoidal thermal conduction seat are integrally formed on the base, the PCB is arranged on the tapered support columns, positioned through penetrating two positioning columns of the PCB and fixed to the thermal conduction seat by combining a bolt, the two positioning columns have different cross sections, the tapered support columns are positioned in the cover plate to cause the cover plate and the base to be buckled tighter and tighter, a triangular malassembly prevention mark is arranged on the position, close to the right rear corner, of the top of the cover plate, four rectangularly-distributed upwards-extending cylinders are integrally formed on the base, threaded installation blind holes corresponding to the cylinders are formed in the back of the base, and a plurality of right-left extending bar-type thermal conduction grooves are formed in the back of the base. By adopting the structure, the problems that the base and the cover plate, and the PCB and the base shake slightly after being installed, the temperature of part of the PCB is too high, and the cover plate and the PCB are arranged reversely are effectively avoided, and the control box component special for power-assisted steering has as a dustproof effect.
