Abstract

The utility model discloses a car anterior segment structure is middle part hollow frame shape structure by entablature, bottom end rail, left stand and right stand welding, the bottom end rail is made by square pipe and is passed through bending machine bending forming. By adopting the utility model, the lower beam is made of the square tube, the square tube can be formed by bending the tube bender, the forming is simple and quick, when the structure of the lower beam is adjusted, a new lower beam can be manufactured only by changing the bending angle and the position, and the platform expansibility of the lower beam is enhanced; the lower cross beam does not need to develop a die, so that the development cost of the vehicle body is saved, the development period is shortened, and the processing cost of the lower cross beam is reduced; in addition, the lower cross beam is made of the square tubes, so that the section size of the lower cross beam is reduced, the middle space of the frame-shaped structure is larger, and the installation of subsequent workpieces is facilitated.

Description

Automobile front section structure

Technical Field

The utility model relates to a body frame, especially a car anterior segment structure.

Background

The front end frame of the automobile is commonly used in two structures of PP + 40% GF injection molding and sheet metal stamping welding. The injection molding type front end frame structure generally depends on the development of a supplier, and the product cost is higher. The sheet metal stamping and welding structure needs a large enough section space to ensure the strength and the bending rigidity, and influences the Z-direction arrangement space of the radiator. In addition, the bottom end rail needs 4 great mould developments at least for need to change the mould promptly when the bottom end rail structure changes, make the platform expansibility of bottom end rail relatively poor, the processing cost is higher.

Disclosure of Invention

The utility model aims to provide a: the problem that the platform expansibility of the bottom end rail of automobile anterior segment is relatively poor among the prior art is solved, and an automobile anterior segment structure with good bottom end rail expansibility is provided.

In order to realize the purpose of the utility model, the utility model provides a following technical scheme:

the utility model provides an automobile forepart structure, is the hollow frame shape structure in middle part by entablature, bottom end rail, left stand and right stand welding, the bottom end rail is made by square pipe and is passed through bending machine bending.

According to the technical scheme, the lower cross beam is made of the square tube, the square tube can be formed by bending through the pipe bending machine, the forming is simple and quick, a new lower cross beam can be manufactured only by changing the bending angle and the position when the structure of the lower cross beam is adjusted, and the platform expansibility of the lower cross beam is enhanced; the lower cross beam does not need to develop a die, so that the development cost of the vehicle body is saved, the development period is shortened, and the processing cost of the lower cross beam is reduced; in addition, the lower cross beam is made of the square tubes, so that the section size of the lower cross beam is reduced, the middle space of the frame-shaped structure is larger, and the installation of subsequent workpieces is facilitated.

Furthermore, two mounting brackets are welded along the length direction of the lower cross beam and used for mounting a radiator. The lower cross beam in the shape of a square tube reserves more space for a frame structure, facilitates the arrangement of radiators with different sizes, and is beneficial to the expansion of a platform.

Further, the mounting bracket is welded on the lower cross beam through carbon dioxide arc welding. The welding of the mounting bracket is convenient.

Furthermore, the cross section of the upper cross beam is of a U-shaped structure, and the left stand column and the right stand column are bent into a groove-shaped structure through sheet metal parts.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the lower cross beam is made of square tubes, the square tubes can be bent and formed by a pipe bending machine, the forming is simple and quick, when the structure of the lower cross beam is adjusted, a new lower cross beam can be manufactured only by changing the bending angle and the position, and the platform expansibility of the lower cross beam is enhanced; the lower cross beam does not need to develop a die, so that the development cost of the vehicle body is saved, the development period is shortened, and the processing cost of the lower cross beam is reduced; in addition, the lower cross beam is made of the square tubes, so that the section size of the lower cross beam is reduced, the middle space of the frame-shaped structure is larger, and the installation of subsequent workpieces is facilitated.
