Abstract

The invention discloses a battery mounting structure. The battery mounting structure comprises a battery tray used for containing a battery, a car body metal plate for fixing the battery tray and a fastening part used for connecting the battery tray with the car body metal plate. The battery tray is a magnesium alloy battery tray or aluminum alloy battery tray, a first isolation coating is arranged between the battery tray and the car body metal plate, and an isolation gasket is arranged between the battery tray and the fastening part. The first isolation coating is arranged for isolating thebattery tray and the car body metal plate, the electrochemical corrosion between the battery tray and the car body metal plate is prevented, meanwhile, the isolation gasket is used for preventing theelectrochemical corrosion between the fastening part and the battery tray, the battery mounting structure is stable in connection, and the electrochemical corrosion between the battery tray and the car body metal plate and between the battery tray and the fastening part is solved.

Description

technical field

[0001] The invention relates to the technical field of vehicles, in particular to a battery installation structure and an automobile. Background technique

[0002] In order to achieve the goal of reducing the weight of automobiles, the prior art recommends the use of lightweight metals—magnesium alloys or aluminum alloys—as battery tray materials. However, since the existing car body structural parts and fasteners (such as screws and nuts) are mostly made of carbon steel or other high-strength steel materials, and there is a large potential difference between magnesium alloys, aluminum alloy materials and carbon steel materials, magnesium Alloy battery trays (or aluminum alloy battery trays) are prone to electrochemical corrosion after they are fixedly connected to the car body structure (such as car body sheet metal), which will lead to a decrease in the performance of the battery tray. At the same time, compared with steel materials, magnesium alloy and al...
