A mid-engine extended-range electric vehicle

Abstract

The invention provides a range-extended electric vehicle with a mid-engine, comprising a vehicle body, a turboshaft engine (1), a battery pack (2), a generator (3), a vehicle controller (4), and a drive motor (5) , gas controller (6), battery controller (7), gas storage tank (8) and air intake box (12), it is characterized in that, described vehicle body comprises vehicle body, and the bottom structure of described vehicle body forms Automobile frame, the described turboshaft engine (1) is arranged and installed between the front and rear axles and on the automobile frame near the rear axle, the output shaft axis of the turboshaft engine (1) is located on the symmetry plane of the automobile body, and the turboshaft The air inlet of the engine (1) faces the rear of the vehicle, and the air intake box (12) communicates with the air inlet of the turboshaft engine (1), and the air intake box (12) is connected to the air intake grille on the body cover through a pipe connected. The range-extended electric vehicle with the engine in the middle of the invention has the characteristics of high energy conversion efficiency, good operability, long cruising range and high structural strength of the vehicle body.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to an extended-range electric automobile related to engine layout. Background technique [0002] Modern cars mainly include cars with traditional piston engines as the power source, as well as pure electric and plug-in cars that use batteries to store energy and are driven by electric motors. A hybrid electric vehicle (HEV) is a new type of vehicle that has two sets of power systems, a traditional piston engine and an electric motor. Existing hybrid vehicles generally adopt a mechanical power hybrid structure, with two complete power systems, including clutches, gearboxes, differentials, etc., the structure is relatively complex, and the battery energy is very small, only for auxiliary driving and braking energy recovery role. A tandem HEV, that is, an extended-range electric vehicle, is directly driven by a motor and has a simple structure, and the battery is on a benign plat...

AI Technical Summary

Problems solved by technology

However, for the range-extended electric vehicle with the front engine, the layout space of the battery pack is greatly squeezed due to the layout position of the engine and the balance requirements of the front and rear wheels, so that the car can continue driving in the driving mode that only discharges the battery pack. mileage affected

[0006] Modern small cars generally adopt a load-bearing body or a non-load-bearing body. Although the load-bearing body is easy to process, the strength of the frame and the overall frame is not high, and the non-load-bearing body also has the defect of low body strength.
