DETAILED DESCRIPTION

[0014] like Figures 1 to 4As shown, the purpose of the present invention is achieved by adopting the following scheme: a lightning protection type load-bearing vehicle body, comprising a left side wall 8, a right side wall 2, a front side wall 9, a rear tail plate 3, a floor 12 and a top plate 1, the lower end of the left side wall 8 is connected and fixed to the left lower side plate 7, the lower end of the right side wall 2 is connected and fixed to the right lower side plate 4, the upper ends of the left and right side walls are connected and fixed to the top plate 1, the front ends of the left and right side walls are connected and fixed to the front side wall 9, the rear ends of the left and right side walls are connected and fixed to the rear tail plate 11, the left and right lower side plates are connected and fixed to the floor 12, the left and right lower side plates are V-shaped and arranged at the lower ends of the left and right side walls, the angle between the left and right lower side plates is 94-118°, a bottom V-shaped plate 6 is arranged below the vehicle body bottom plate, the angle of the bottom V-shaped plate 6 is 94-118°, and a bottom protective cover 5 is connected and fixed below the bottom V-shaped plate 6, and the bottom protective cover 5 is a V-shaped protective cover, and the angle of the bottom protective cover 5 is 94-118°. The angle of the three-layer V-shaped structure is obtained through a large number of tests and simulation analysis, and the best angle is adopted. The three-layer V-shaped structure is superimposed to form a multiple lightning protection system. Through multi-layer shunt unloading and step difference unloading, the impact of the explosion on the whole vehicle can be significantly reduced, and the impact energy transmitted to the passenger compartment can be minimized. An inclination angle α is set between the left and right side panels and the top plate 1, and the inclination angle α set between the left and right side panels and the top plate 1 is 35 to 45°. A front door deflector 10 is set at the lower end of the front side panel 9, and a rear door deflector 11 is set at the lower end of the rear tail panel 3. The design of the deflector can disperse the impact of the explosion. The floor 12 is a suspended floor, and a suspended vibration damping pad 13 is arranged between the floor 12 and the bottom of the vehicle body.
