Electric automobile lower body threshold beam structure capable of placing chassis pipeline

Abstract

The invention discloses an electric automobile lower body threshold beam structure capable of arranging a chassis pipeline, which comprises a lower body threshold beam main beam body, a cooling pipeline and a brake pipeline, and is characterized in that the lower body threshold beam comprises an upper beam body, a middle beam body and a lower beam body, and the upper beam body is a sectional material structure including two inserting holes, the middle beam body is located on the lower portion of the upper beam body and is arranged to be of a sectional material structure comprising four inserting holes, the lower beam body is located on the lower left side of the middle beam body and is arranged to be of a single-hole sectional material structure, a single-hole cavity is formed in the lowerbeam body, and a horizontal extending plate horizontally extending rightwards is arranged on the lowermost portion of a sectional material of the lower beam body. A U-shaped cavity is formed betweenthe horizontal extending plate and the bottom of the middle beam body. The cooling pipeline is arranged in the single-hole cavity of the lower beam body, and the brake pipeline is fixed in the U-shaped cavity. According to the electric automobile lower body threshold beam structure capable of placing the automobile chassis pipeline, the protection on the cooling pipeline and the brake pipeline canbe enhanced, the risk of being scratched is reduced, a battery pack can be enlarged conveniently, the cruising ability of an automobile is improved, and practicability is high.

Description

technical field [0001] The invention relates to a threshold beam structure of the lower body of an electric vehicle capable of placing chassis pipelines, and relates to the technical field of assembly of automobile parts. Background technique [0002] When the chassis pipeline layout of traditional automobiles is applied to electric vehicles, its layout under the floor has the following disadvantages: First, when the pipelines of the traditional structure are placed under the lower body of the vehicle, they may be scratched during driving. Risk; second, when the traditional structural pipeline is placed in the lower part of the vehicle body, it will occupy a lot of space under the floor, which is not conducive to increasing the volume or quantity of battery packs for electric vehicles, and thus is not conducive to improving the battery life of the vehicle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electr...
