Problems solved by technology

[0002] With the continuous improvement of energy saving and emission reduction requirements in the automotive field, electrification and lightweight composite materials have gradually become a new trend. The installation of battery boxes on composite material structures has gradually become the key to further expand the production of composite materials for electric composite materials. In particular, the installation of the battery box on the composite material sandwich panel often has problems such as insulation and safety protection, and the connection strength is low, which cannot meet the engineering requirements

Abstract

The invention relates to a connection structure and method of an electric motor coach overhead type battery. A body of the electric motor coach is made of a composite material. The overhead type battery is a main power source of the electric motor coach. The connection structure comprises the overhead type battery, a battery supporting base set and a composite coach top. The overhead type battery comprises a plurality of battery units, the weight of each battery unit is less than 100 kg, four corners of each battery unit are provided with connection lugs, and the multiple battery units are arranged in a matrix mode. The battery supporting base set comprises a plurality of battery supporting bases which are arranged in a matrix mode. The connection structure and method of the electric motor coach overhead type battery have the beneficial effects that the insulation and protection problems in the battery box installation process are solved, and meanwhile, the connection strength between a composite laminboard connection piece and a battery box lug type connection piece is enhanced.
