The invention discloses a steering wheel and steering column fixing support based on head-on collision of passenger cars. The steering wheel and steering column fixing support comprises a frame including first cross beams, second cross beams, first longitudinal beams, first energy absorption boxes and oblique beams. The first cross beams are transversely and horizontally arranged along the passenger cars. The second cross beams are transversely and horizontally arranged along the passenger cars and located above the vertical direction of the first cross beam in a certain spaced way. The firstlongitudinal beams are parallelly arranged in the vertical direction at intervals, and the middles of the first longitudinal beams are hinged to the second cross beams. The first energy absorption boxes extend in the longitudinal direction of the passenger cars and are fixed between the bottoms of the first longitudinal beams and the first cross beams. The oblique beams are obliquely arranged along the passenger cars, and one end of each oblique beam is fixedly connected with the top end of the corresponding longitudinal beam, and the other end of each oblique beam is fixedly connected to theupper portion of a steering mechanism. According to the steering wheel and steering column fixing support based on head-on collision of passenger cars, the oblique beams can drive a steering column and a steering wheel move away from a driver around a hinge point, and the safety during collision is improved.
