Embodiment Construction

[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0033] Such as figure 1 As shown, a lightweight base plate for an electric vehicle, the base plate is a 5-layer composite structure, fixed together by rivets 1, from bottom to top are high-strength metal sheet 2, foamed aluminum plate 3, high-strength metal sheet 2, foamed aluminum plate 3 and high-strength The thin metal plate 2 adopts a vertical metal skeleton 4 around the base plate to surround and reinforce, so that the base plate is integrated, so that the strength is not reduced, and the weight of the vehicle body is greatly reduced. The vertical metal frame 4 is a thick plate or profile with a thickness of 12mm, the thickness of the foamed aluminum plate 3 is 5mm, and the thickness of the high-strength metal sheet 2 is 1.2mm.

Abstract

The invention discloses a lightweight electric automobile floor. The floor is of a five-layer composite structure, the five layers are fixed together by rivets and are a high-strength sheet metal, a foamed aluminum board, a high-strength sheet metal, a foamed aluminum board and a high-strength sheet metal from bottom to top in sequence, and the periphery of the floor is reinforced by adopting a vertical metallic framework in an encircled manner, so that the floor is integrated, the strength is not reduced, and the body weight is greatly reduced. The structural design is simple, a composite vehicle floor technology for alternatively superposing multiple foamed aluminum layers and multiple high-strength sheet metal layers is adopted, collision deformation of the platform floor is avoided, the passenger safety is protected, fire and explosion caused by collided deformation of a battery pack can be avoided, and energy generated by collision can be effectively absorbed. Meanwhile, the traditional foamed aluminum formula is changed, so that the lightweight electric automobile floor has an excellent energy absorption effect, and the application range of the floor is widened.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a lightweight bottom plate of an electric vehicle. Background technique [0002] The continuous development of modern high-tech has made the problem of electromagnetic interference and electromagnetic compatibility caused by electromagnetic waves increasingly serious, which not only causes interference and damage to electronic instruments and equipment, affects their normal work, and seriously restricts the international competitiveness of my country's electronic products and equipment. It will pollute the environment and endanger human health; in addition, the leakage of electromagnetic waves will also endanger the security of national information security and military core secrets. In particular, the electromagnetic pulse weapon as a new concept weapon has achieved substantial breakthroughs, which can directly strike electronic equipment, power systems, etc., causing temporar...
