Shock absorber fixing support and automobile

The invention provides a shock absorber fixing support and an automobile. The shock absorber fixing support comprises a support body and a bolt hanging head. An automobile shock absorber assembly is fixedly connected with the support body through the bolt hanging head. The support body comprises a first supporting plate and a second supporting plate, wherein the end face of the first end of the first supporting plate is an arc surface; the second supporting plate is arranged opposite to the first supporting plate; the end face of the first end of the second supporting plate is an arc surface; and the arc surfaces can be attached to the outer surface of an axle tube of an automobile drive axle assembly, and the arc surfaces are connected with the outer surface of the axle tube in a welded mode. A welding seam between the support body and the axle tube is expanded by arranging the end face of the first end of the first supporting plate and the end face of the first end of the second supporting plate as welding faces, the melting depth of the welding position is enough, the welding strength of the support is improved, the support can adapt to complex off-road terrains and multi-constraint complex stress situations, the fatigue break risk of the support is avoided effectively, and driving safety is improved.
