Problems solved by technology

[0004] The front floor longitudinal beams are usually arranged on both sides and welded together with the left and right sides of the central channel, which can play a good role in force transmission and body bending resistance. It is complicated, which increases the difficulty of welding the front floor, and also increases the weight of the vehicle body

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] refer to figure 1 , which is a car front floor central channel structure disclosed by the present invention, combined with figure 1 and figure 2 As shown, it includes an inverted U-shaped central channel body 1, and also includes reinforcing components 2 that are symmetrically fixedly connected to both sides of the opening edge of the central channel body 1. The reinforcing component 2 includes a first The reinforcing plate 21 and the first reinforcing arc plate 22 are fixedly connected to the end of the first reinforcing plate 21 away from the opening of the central channel body 1 . The inverted U-shaped central channel body 1 itself can improve the impact deformation resistance in the longitudinal direction, and by increasing the rigidity under the side impact on the first reinforcement plate 21, the first reinforcement arc plate 22 can absorb the...

Abstract

The present invention relates to a central channel structure in the front floor of an automobile, which includes an inverted U-shaped central channel body, and reinforcement components respectively symmetrically fixed and connected to both sides of the opening of the central channel body. The first reinforcing plate on the side and the first reinforcing arc plate fixedly connected to the end of the first reinforcing plate away from the opening of the central channel body. The inverted U-shaped central channel body itself can improve its impact resistance in the length direction A reinforcing plate improves rigidity under side impact, and its first reinforcing arc plate can maintain sufficient toughness while absorbing side impact energy.

Description

technical field [0001] The invention relates to the technical field of automobile structures, in particular to an automobile front floor central channel structure. Background technique [0002] At present, cars play an extremely important role in people's lives. The car body must not only meet the comfort of passengers, but more importantly, ensure the safety of the passengers. designed to minimize personal injury. [0003] In the design of the car body, it is considered that when the car undergoes a severe frontal collision, the left and right front side beams on both sides of the front of the car body will be severely distorted and deformed so that the passenger compartment will be severely squeezed, which will easily cause serious damage to the occupants. Therefore, the front floor longitudinal beam is usually added at the front floor position. In the event of an accident, the front longitudinal beam of the car and the front floor longitudinal beam together play the role...
