An ip67-compliant aluminum alloy battery tray for electric vehicles

Abstract

The present invention relates to the technical field of battery trays. An electric vehicle aluminum alloy battery tray conforming to IP67, comprising an aluminum alloy battery tray, the aluminum alloy battery tray includes a U-shaped base frame, a left cross beam and a right cross beam, the U-shaped base frame includes a support portion, and the support portion includes upper and lower upper and lower beams. The aluminum alloy plate and the lower aluminum alloy plate; the left and right ends of the upper aluminum alloy plate are provided with mirror-symmetrical isosceles trapezoid-shaped gaps; the left and right ends of the lower aluminum alloy plate are provided with mirror-symmetrical rectangular-shaped gaps; The right beam includes a bottom support plate, the bottom support plate includes an upper support plate and a lower support plate arranged up and down, the upper support plate and the lower support plate are connected by connecting bars, and the upper support plate is embedded in the shape of an isosceles trapezoid of the upper aluminum alloy plate. The lower support plate is embedded in the rectangular notch of the lower aluminum alloy plate, and is connected with the lower aluminum alloy plate by welding. This patent reduces the weight of the entire product.

Description

technical field [0001] The invention relates to the technical field of battery trays, in particular to an aluminum alloy battery tray. 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, operation safety and recycling. The density of aluminum is only 1 / 3 of that of steel, and it has obvious effects in reducing weight, reducing noise, increasing speed, reducing exhaust emissions, and improving handling. It is the first choice among lightweight materials for automobiles. [0003] Due to the inherent "big heart" - the power battery, an electric vehicle is hundreds of kilograms heavier than a traditional fuel vehicle of the same level. How to reduce the weight of the battery while ensuring safety and cost control has become a problem for most A questi...

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
