Abstract

The invention discloses an electric car. The electric car comprises a car body, a front subframe, a power battery and a connecting component, wherein the front subframe is installed on the car body, the power battery comprises a power battery shell and a power battery module arranged in the power battery shell, and the power battery shell comprises an upper shell body, a lower shell body and an energy absorption frame; an energy absorption cavity is formed in the energy absorption frame which is connected between the upper shell body and the lower shell body, and an accommodating cavity used for accommodating the power battery module is defined by the energy absorption frame, the upper shell body and the lower shell body; the connecting component is connected between the power battery shell and the front subframe so as to transmit collision energy from the front subframe to the power battery shell during car collision. According to the electric car, the power battery shell and the front subframe are connected through the connecting component and become a part of a car body energy absorption structure, collision energy absorption effect is good, and safety performance is high.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to an electric vehicle. Background technique [0002] The power battery is the power source of hybrid electric vehicles and pure electric vehicles. The power battery usually includes a power battery casing and a power battery module composed of multiple single batteries and accommodated in the power battery casing. The power battery casing is used to protect the power battery. Modules, such as avoiding damage to the power battery module in the event of a vehicle collision. In related technologies, in order to avoid damage to the power battery during a collision in the car, an energy-absorbing area is usually set on the frame to absorb the collision energy, protect the power battery, and avoid the transmission of collision energy to the power battery, especially to avoid the transmission of collision energy to the power battery. Power battery case. In addition, in the rela...
