Embodiment Construction

[0025] In this embodiment, in order to solve a typical layout of the floor of the passenger compartment, the rear mounting points of the front seats (attached figure 1 In 7 and 8) there is no transverse crossbeam, which leads to the crossbeam of the front seat figure 1 Middle 3) and the rear beam (attached figure 1 The distance between the middle structure 4) is relatively large, and the floor sheet metal forms a relatively large plane, which is easy to cause structural resonance due to the stiffness of the floor, resulting in NVH problems. In this embodiment, the original welding process of the floor assembly is not changed, and the floor sheet metal can be directly welded together with other connecting parts as required. There is no conflict between the floor and the surrounding structure, and the shape of the surrounding structure does not need to be changed.

[0026] In a typical arrangement for the floor of the passenger compartment, the floor in this area (with figure ...

Abstract

The invention relates to a car passenger compartment floor rib arrangement structure, which comprises a floor (5), leakage holes (9, 10) and annular reinforcing ribs, wherein the leakage holes (9, 10) are formed on the floor (5); the annular reinforcing ribs comprise a first reinforcing rib (11) and a second reinforcing rib (14); the number of the leakage holes (9, 10) is two; and the first reinforcing rib (11) is a reinforcing rib which is arranged on the straight floor surface of the floor (5) by using the first leakage hole (9) as a circle center, and the second reinforcing rib (14) is a reinforcing rib which is arranged on the straight floor surface of the floor (5) by using the second leakage hole (10) as a circle center.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to a reinforcement form for the floor structure of a car passenger compartment. Background technique [0002] The structure of the passenger compartment of a car is usually formed by punching a single-layer plate, and its periphery is welded to the front and rear beams, the middle channel, and the longitudinal beams. Leakage of paint fluid. In order to reduce the weight of the car body, the floor thickness is usually relatively thin, generally one of the thinnest parts of the car body. In order to improve the rigidity of the floor, so that the occupants will not have a soft feeling when stepping on it, and at the same time, avoid the noise in the car caused by resonance caused by insufficient local rigidity, and reduce the NVH performance, it is generally necessary to adopt certain methods to improve the performance of the floor. Increasing the thickness of floor sheet metal and...
