IP67-compliant electric vehicle aluminum alloy battery tray

Abstract

The invention relates to the technical field of battery trays. An IP67-compliant electric vehicle aluminum alloy battery tray comprises an aluminum alloy battery tray; the aluminum alloy battery traycomprises a U-shaped underframe, a left cross beam and a right cross beam; the U-shaped underframe comprises a support portion; the support portion comprises an upper aluminum alloy plate and a loweraluminum alloy plate which are arranged vertically; the left and right ends of the upper aluminum alloy plate are provided with the isosceles trapezoidal notches arranged in a mirror symmetry mode; the left and right ends of the lower aluminum alloy plate are provided with the rectangular notches arranged in a mirror symmetry mode; both the left cross beam and the right cross beam are provided with bottom support plates; the bottom support plate comprises an upper support plate and a lower support plate arranged vertically; the upper support plate and the lower support plate are connected through a connecting strip; the upper support plate is embedded in the isosceles trapezoidal notch of the upper aluminum alloy plate to be welded and connected with the upper aluminum alloy plate; and thelower support plate is embedded in the rectangular notch of the lower aluminum alloy plate to be welded and connected with the lower aluminum alloy plate. The weight of the whole product is reduced.

Description

Technical field [0001] The invention relates to the technical field of battery trays, in particular to aluminum alloy battery trays. Background technique [0002] Among the lightweight materials for automobiles, the comprehensive cost performance of aluminum alloy materials is higher than that of steel, magnesium, plastics and composite materials. It has comparative advantages in terms of application technology, operational safety and recycling. The density of aluminum material is only 1 / 3 of that of steel, and its effects in terms of weight reduction, noise reduction, speed increase, exhaust emission reduction, and handling enhancement are obvious. It is the first choice among lightweight materials for automobiles. [0003] Due to the inherent "big heart"-the power battery, an electric car can gain hundreds of kilograms heavier than a traditional fuel car of the same level. How to reduce the weight of the battery while ensuring safety and cost control has become the most troubleso...

Problems solved by technology

[0004] However, whether it is to increase the energy density of batteries, or to reduce weight such as new battery materials and new technology applications, due to the limitations of cost and technology, there is still a long way to go before large-scale popularization

How to reduce the weight of the aluminum alloy battery tray while achieving its waterproof performance is one of the practical and feasible solutions for the weight reduction of the battery at this stage. The current weight reduction of the aluminum alloy battery tray simply stays at thinning, which is not conducive to the battery. Guarantee of strength and waterproofness
