Description

Compartment floor

Technical Field

The invention belongs to the technical field of van manufacturing, and particularly relates to a van body floor.

Background

In the manufacturing process of the compartment body floor of the compartment body, in the related art, a longitudinally paved floor and a bottom cross beam welded under the longitudinally paved floor are adopted to form the compartment body floor, and in order to ensure the bending resistance and the torsional strength of the compartment body, the dimensions of the longitudinally paved floor and the bottom cross beam in the height direction need to be ensured. For example, the combination of a longitudinal floor with the height of 30mm and a bottom cross beam with the height of 100mm is adopted, so that the bending resistance and torsion resistance of the compartment body are ensured. The disadvantages of the related art are that: on one hand, after the 30mm high longitudinal floor and the 100mm high bottom cross beam are welded, the overall height reaches 130mm, and in order to ensure that the overall height of the compartment body meets the requirements of the regulations, the volume inside the compartment body is limited by the total height of the floor, so that the overall volume of the compartment body is reduced. On the other hand, the longitudinally-paved floor and the bottom cross beam need to be welded in a staggered arrangement, and the welding strength is high, the deformation is large, and the time and the labor are wasted.

Therefore, there is a need to provide a new car floor to solve the above technical problems.
