A front floor assembly structure suitable for platform vehicles

Abstract

A front floor assembly structure suitable for platform vehicles, the central channel assembly includes a central channel and a front floor sub-beam located below the rear end of the central channel; the front floor frame assembly includes two front seat front beams, a front seat The rear seat beam and the central channel reinforcement plate, the two front seat front beams are arranged on the left and right sides of the front end of the central channel reinforcement plate, respectively including the connected front seat beam mounting plate and the front seat beam; the front seat rear beam is set on The rear part of the central channel reinforcement plate includes the middle section beam, the left section beam and the right section beam, and the middle section beam is overlapped and arranged on the central channel reinforcement plate. Through the design of the front seat front cross member, front seat rear cross member and central tunnel, the front floor assembly structure establishes the body platform parts, which can realize the common use of components and the platformization of the front floor to the greatest extent, and can meet the body of various widths Front floor assembly requirements, thereby saving manufacturing costs to the greatest extent and shortening the development cycle.

Description

technical field [0001] The invention belongs to the technical field of automobiles, relates to the field of vehicle structures, in particular to a front floor structure of a vehicle. Background technique [0002] Automotive products not only need to meet the differentiated requirements of different customers and countries in different regions, but also need to realize the maximum economic benefits of automakers. Platformization, as one of the important strategies to enable automakers to reduce costs and improve R&D efficiency, has been valued by automakers. The basic platform definition can be roughly divided into three forms: narrow sense, broad sense, and flexible platform development. Regardless of the platform definition, the front floor-related components are one of the core components. [0003] In the common front floor assembly structure, whether it is an integral type or a split type front floor, the generalization degree of components is relatively low. When the b...

Problems solved by technology

When the body width of a remodeled vehicle needs to be increased, the front floor assembly can borrow fewer parts, mainly the door sill, central tunnel (split type), and longitudinal beams, while the front seat beam cannot be borrowed; when the shifter, When components such as the handbrake need to be replaced, due to structural limitations, the installation of the reinforcement plate cannot be used universally and needs to be redeveloped, which is not conducive to the universalization of the front floor assembly components

In the development of new cars and remodeled cars, the front floor assembly of non-platform models is likely to prolong the development cycle and increase the manufacturing cost
