The invention provides a front floor central tunnel assembly for a car body, which has leak tightness and high direct impact performance. The front floor central tunnel assembly for the car body comprises a central channel body and a central channel bracket body, wherein the central tunnel bracket body is hermitically fixed on the central tunnel body through flanges at the periphery, and technological holes of the central tunnel assembly are arranged on the central channel bracket body. As the central tunnel bracket body separated from the central tunnel body is arranged and the technological holes are arranged on the central tunnel bracket body, holes on the central tunnel body are avoided; moreover, as the central tunnel bracket body is hermetically fixed on the central tunnel body, no communication between the technological holes on the central tunnel bracket body and the outside to the car body is guaranteed, and the problem of leakage noise of the technological holes is solved; and meanwhile, the cross section of the front floor central tunnel assembly is increased due to the additional arrangement of the central tunnel bracket body, the number of closed sections is increased, and the direct impact performance is improved.
Description
technical field [0001] The invention relates to the technical field of automobile body manufacturing, in particular to a channel assembly in the front floor of a vehicle body. Background technique [0002] Due to the excessive holes in the front floor of the existing automobile body, the wind noise in the car will be too large during the wind noise test, and most of the central channel assemblies are integrally formed by a single piece of steel, making it The number of closed sections surrounded by the section is small, and the frontal impact performance is not high. Contents of the invention [0003] The object of the present invention is to propose a tunnel assembly in the front floor of the vehicle body with airtightness and high frontal impact performance. [0004] According to the present invention, the middle channel assembly of the front floor of the vehicle body mainly includes the middle channel body and the middle channel support body, the middle channel suppor...
