Background

With the factors of global warming, reduction of petroleum energy, environmental problems caused by increase of carbon emission and the like, specific energy-saving and emission-reducing strategies are put forward by various countries. Automobiles, as a necessity in daily life, consume a large amount of petroleum energy every year, and generate a large amount of carbon emissions. In order to implement the carbon emission strategy proposed by the state, reduce the consumption of oil and the pollution to the environment, the automobile weak-mixing technology (the patent mainly relates to the HEV type) is vigorously developed.

Based on the technical comparison research in the industry, the last generation HEV motorcycle type power battery is arranged in the trunk, and as disclosed in patent document CN206336117U, the power battery pack mounting structure assembly and the automobile have great disadvantages for the utilization of the trunk space.

For this reason, the new generation of technologies of mainframe factories such as Toyota, modern and Honda all adopt the way of arranging power batteries under the rear row seats, but also occupy the space of the original seat fixing structure, and bring new challenges to the fixing of the rear row seats. The technical route adopted by the manufacturers is a structural mode that the cushion is directly connected with the battery, although the cushion has advantages on weight, the platform development of different types of vehicle battery packs cannot be realized, and great defects exist on cost and development period.

In domestic main engine plants, such as the installation structure of the vehicle battery disclosed in patent document CN201800516U, although the arrangement position is under the rear seat, it requires the floor to provide a concave surface for placing the battery, there is a special limitation on the floor type, and the installation structure of the seat is not involved.
