[0002] The cab of a commercial vehicle light truck is a non-load-bearing body, and the cab is connected to the frame through a flip lock mechanism. The floor at the connection with the front support receives a large impact stress during driving. Acting on the front floor area, the two kinds of stress are superimposed, resulting in cracks at the front beam of the light truck cab floor
At present, the floor structure design of the light truck cab is too weak. The longitudinal beam bears the load on the upper part of the cab, the beam bears the lateral load and the load transmitted by the torsion of the vehicle body. At the same time, the front beam is subjected to long-term driving impact stress, and the floor of the body will crack after fatigue

The invention relates to a light truck cab floor assembly. The assembly comprises a floor frame composed of a front cross beam assembly, a left longitudinal beam assembly, a right longitudinal beam assembly and a back upper cross beam assembly. A front floor assembly and a back floor assembly are respectively mounted on one lateral face of the floor frame, a left T-shaped strengthening board is arranged at the connecting position of the left longitudinal beam assembly and the front cross beam assembly and a right T-shaped strengthening board is arranged at the connecting position of the right longitudinal beam assembly and the front cross beam assembly, so that the force between longitudinal and transverse beams is not concentrated on the front cross beam assembly after being transmitted by the two strengthening boards. A horizontal forward extension place formed by the upward protrusion of the front floor assembly and an inverted groove steel side formed by the upward protrusion of the front cross beam assembly form a sealed cavity; accordingly, a torsion box is formed, section factors of the front portion of the cab is improved, and simultaneously, torsion rigidity of the cab can be improved effectively. The light truck cab floor assembly effectively improves the torsion rigidity and bending rigidity of the whole truck, and avoids the problem of cracking of the light truck cab floor.
Description
technical field [0001] The invention belongs to the technical field of automobile bodies, and in particular relates to a light truck body floor structure. Background technique [0002] The light truck cab of a commercial vehicle is a non-load-bearing body. The cab is connected to the frame through a flip lock mechanism. Acting on the front floor area, the two stresses are superimposed, resulting in cracks at the front beam of the light truck cab floor. At present, the design of the floor structure of the light truck cab is too weak. The longitudinal beam bears the load on the upper part of the cab, the beam bears the lateral load and the load transmitted by the torsion of the vehicle body. At the same time, the front beam is subjected to the impact stress of driving for a long time, and the floor of the body is cracked after fatigue. Contents of the invention [0003] In order to avoid stress concentration on the floor of the light truck cab, ensure the effective transmi...
