Problems solved by technology

[0003] As the country vigorously advocates green environmental protection, electric vehicles have become a development trend. The mileage of electric vehicles is closely related to the quality, and the weight of the body is imperative. From this, a series of all-aluminum bodies are derived. Aluminum profiles, the rear section of the front longitudinal beam needs to be connected with multiple structural parts, the use of aluminum profiles and aluminum plates will increase the number of structural parts, increase the types of connections, make assembly difficult, complex processing technology, increase production costs, and reduce efficiency
[0004] The rear section of the front...

Abstract

The invention relates to the field of vehicles, in particular to a downward-bending longitudinal beam which is an integrally cast component. The downward-bending longitudinal beam comprises a front section, a middle section and a rear section, the vertical cross sections of the front section and the middle section are in an I shape, grid-shaped reinforcing ribs are arranged on the two sides of thefront section and the middle section, and the reinforcing ribs are arranged along the extending direction of the middle section. For solving the problems, the die-casting aluminum down-bending longitudinal beam which is convenient to connect and good in structural rigidity is provided, a plurality of sectional materials and plates can be replaced, the problems that lap joint of the plurality of sectional materials is difficult, and dimensional tolerance is difficult to guarantee are solved, the weight can be reduced, the downward-bending longitudinal beam can be machined to the shape with thecomplex structure and can be conveniently assembled with a front section of a front longitudinal beam, a damper base, a wheel coating plate, a stand column A, a threshold beam and the like, assembling is easy and convenient, connection types are reduced, and work efficiency is improved.

Description

technical field [0001] The present application relates to the field of vehicles, in particular to a bowed longitudinal beam and a vehicle. Background technique [0002] Most of the current vehicle body structures are connected by welding, which requires relatively high processing accuracy and welding equipment. Especially in the connection between the front longitudinal beam and the car, this problem is particularly obvious due to the large number of connection points. [0003] As the country vigorously advocates green environmental protection, electric vehicles have become a development trend. The mileage of electric vehicles is closely related to the quality, and the weight of the body is imperative. From this, a series of all-aluminum bodies are derived. Aluminum profiles, the rear section of the front longitudinal beam needs to be connected with multiple structural parts. The use of aluminum profiles and aluminum plates here will increase the number of structural parts,...
