The invention discloses a novel multifunctional integrated test vehicle and a method for applying the same, and is applied to novel multifunctional integrated test vehicles and methods for applying the same. The novel multifunctional integrated test vehicle comprises a lower-layer panel of a vehicle body. Four rectangular empty slots (11) are formed in the lower side of the lower-layer panel (8) of the vehicle body, wheels (6) are mounted beside the empty slots, four fixing support columns (5) and a central shaft (4) of a power wire box are arranged on the lower-layer panel, an upper-layer panel (7) is arranged on the fixing support columns, two groups of X-shaped slide rails (13) are arranged on the upper-layer panel, sliding fixing block pieces (12)are fittingly arranged in the two groups of X-shaped slide rails, special support fixing grooves (3) for insulating rods (14) are formed in the right side of the upper-layer panel, a handle barrier (9) is arranged on the rear side of the upper-layer panel, and a spring connecting rod (10) and a cart handle (1) are arranged on the handle barrier. The novel multifunctional integrated test vehicle and the method have the advantage that shortcomings of simple designs and rough materials of common carts, limited equipment and tools loaded in the common carts, easiness in bumping and slipping and damage to the equipment and the tools can be overcome by the aid of the novel multifunctional integrated test vehicle and the method.
