Embodiment Construction

[0027] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0028] For the convenience of description, define the length direction of the lower body of the vehicle platform as the first direction.

[0029] Such as Figure 1-Figure 4 As shown, this kind of platform body floor structure includes a front floor assembly 101 and a rear floor assembly 102. The rear floor assembly 102 includes a mid-sole connecting plate 201 connected to the front floor of the front floor assembly 101, including a The rear section of the sill connected to the front sill of the floor assembly 101 includes the rear longitudinal beam of the middle channel connected with the longitudinal beam of the central channel of the front floor assembly 101 and the rear longitudinal beam connected with the front floor longitudinal beam of the front floor assembly 101 . The front floor i...

Abstract

The invention discloses a platformization vehicle body floor structure. The platformization vehicle body floor structure comprises a front floor assembly and a rear floor assembly, wherein the front floor assembly is connected with the rear floor assembly through a connecting part of which the length is greater than the changing quantity of wheelbase of a lower vehicle body. According to the platformization vehicle body floor structure disclosed by the invention, the change of the wheelbase of the lower vehicle body is realized through changing the length dimension of a part at a joint of the rear floor assembly and the front floor assembly in the first length direction; the connecting position of the front floor assembly and the rear floor assembly can be adjusted to meet the adjusting requirement of the wheelbase of the lower vehicle body, so that the matching requirement of the vehicle body floor for the lower vehicle body with different wheelbases is met; the use rate of generalization parts and components can be increased, the change of the wheelbase of a platformization vehicle can be realized through the minimum change of parts, and the development period and the cost are reduced.

Description

technical field [0001] The invention belongs to the field of automobile body structure design, and in particular relates to a platform body floor structure and an assembly method thereof. Background technique [0002] With the increasingly fierce competition in the automobile market, the pressure on the speed of launching new models and the cost of a single vehicle continues to increase. Therefore, the platform strategy is generally adopted by major automobile companies in the world, which greatly enhances the company's competitiveness. The application of the platform not only promotes the technological revolution in the field of automobile manufacturing, but also has a revolutionary impact on R&D, product supply chain and service chain. In the manufacturing process, a large number of generalized components and assemblies are used for products on the same platform, which greatly reduces manufacturing costs and procurement costs. In the research and development process, a pe...
