The invention relates to a commercial vehicle three-point supporting storage battery fixing and damping structure which is assembled on the inner side of the ventral surface of a left longitudinal beam and the inner side of the ventral surface of a right longitudinal beam of a commercial vehicle frame and comprises a completely-closed U-shaped supporting frame. The tail ends of the supporting frame are arranged on the two sides of an inverted-U-shaped supporting plate, the supporting plate is of a hollow structure, and a supporting rod is arranged in the supporting plate in a penetrating mode. The two ends of the supporting rod are fixed to a left longitudinal beam and a right longitudinal beam, a fixing support is arranged at the arc-shaped end of the supporting frame and connected to the bottom face of a tail cross beam of a frame, a bottom plate is arranged on the supporting frame, and a storage battery frame is fixed to the bottom plate. The structure is reasonable in arrangement and uniform in stress, flexible deformation of the storage battery frame is eliminated, and structural damage caused by fatigue is relieved; high-frequency vibration of the storage battery frame is reduced, so that the problem of loosening of an internal connection structure is relieved; the integration degree is high; not only is the assembly manufacturability good, but also the structural strength and reliability are improved; and the component quality is effectively improved.
