Steel and aluminum combined instrument board cross beam

Abstract

The invention relates to a steel and aluminum combined instrument panel cross beam which comprises an aluminum pipe beam, the aluminum pipe beam is of a tubular structure made of aluminum materials, the middle of the aluminum pipe beam is bent downwards to form a U shape, an aluminum host installation support is arranged below the middle of the aluminum pipe beam and connected with the aluminum pipe beam in an arc welding mode, and the aluminum host installation support is connected with the aluminum pipe beam in an arc welding mode. The left side of the aluminum host installation support is welded with an aluminum left lower guard board installation support, the left end and the right end of the aluminum tubular beam are respectively provided with a steel instrument board installation support, the front portion of the left side of the aluminum tubular beam is provided with a steel front wall connection support, and the rear portion of the left side of the aluminum tubular beam is provided with a steel steering column installation support. An aluminum glove box installation support is installed on the lower portion of the right side of the aluminum pipe beam and used for installing an interior glove box, and a steel air bag frame installation support is installed on the front portion of the right side of the aluminum pipe beam. While enough strength, rigidity, modality and safe collision requirements are guaranteed, the self weight is reduced to the maximum extent, and meanwhile compared with a common steel cross beam, the cost is slightly increased.

Description

[technical field] [0001] The invention relates to the technical field of automobile manufacturing, in particular to a steel-aluminum combined instrument panel beam. [Background technique] [0002] At present, the existing new energy pure electric and hybrid vehicles usually use steel dashboard beams. The current development trend of new energy vehicles is the trend of intelligent large screens. There are more installation points for dashboard beams, which directly leads to more installation brackets. , The weight of the steel dashboard beam increases, because the steel dashboard beam cannot achieve lightweight, which affects the weight of the vehicle, thereby affecting the cruising range of new energy vehicles. With the increasingly stringent requirements for lightweight, more and more other lightweight materials are used, such as magnesium-aluminum alloy, plastic brackets, etc., but the cost of magnesium-aluminum alloy is relatively high, and only high-end models use it, an...

[0002] At present, the existing new energy pure electric and hybrid vehicles usually use steel instrument panel beams. The current development trend of new energy vehicles is the trend of intelligent large screens. There are more installation points for instrument panel beams, which directly leads to more installation brackets. , the weight of the steel dashboard beam increases, because the steel dashboard beam cannot achieve lightweight, which affects the weight of the vehicle, thereby affecting the cruising range of new energy vehicles

With the increasingly stringent requirements for lightweight, more and more lightweight materials are used, such as magnesium-aluminum alloy, plastic bracket, etc., but the cost of magnesium-aluminum alloy is relatively high, only high-end models use it, and the economic benefit is not good
