Problems solved by technology

[0005] However, due to the limited layout space of the front cabin of a small car, the layout of the drive assembly system often takes up most of the space in the front cabin.
In addition, the volume of the range extender is relatively large. In the layout of the front cabin of the prior art, noise and vibration are unacceptable to customers.
In addition, fixing the range extender in the front compartment of the traditional vehicle drive assembly system cannot meet the layout requirements of the entire vehicle according to the layout space of the front compartment.

Abstract

The invention provides an electric vehicle as well as forecabin arrangement structure and method. In the invention, the forecabin arrangement structure of the electric vehicle comprises a power assembly system which comprises a driving system and a range extender system, wherein the driving system is fixed through adopting three-point suspension in a forecabin; and the suspension points pass through the gravity centers of a motor and a speed reducer. According to the invention, the left-side space of the forecabin can be effectively utilized in a maximum range to ensure that enough right-sidespace can be left for the design of the distance-increasing equipment.

Description

Technical field [0001] The present invention relates to the field of electric vehicle design. Specifically, the present invention relates to an electric vehicle and its front cabin arrangement structure and corresponding front cabin arrangement method. Background technique [0002] As a representative of new energy vehicles, electric vehicles have the advantages of economy and cleanliness. However, due to the limitation of the layout space of the whole vehicle, the batteries cannot be arranged indefinitely and their power can be increased. In this way, electric vehicles may reach a bottleneck in terms of driving range. Can not meet the actual needs of customers, that is, can not travel long distances like traditional gasoline vehicles; thus limiting the promotion of electric vehicles. [0003] In order to extend the driving range of electric vehicles, an electric vehicle with a range extender has been developed. Among them, the method of arranging a range extender in the front cab...
