Mid-engine incremental stroke electric vehicle

Abstract

The invention provides a mid-engine incremental stroke electric vehicle. The electric vehicle comprises a vehicle body, a turbo shaft engine (1), a battery pack (2), a generator (3), a whole vehicle controller (4), a driving motor (5), a gas controller (6), a battery controller (7), a gas holder (8) and a gas inlet tank (12), and is characterized in that the vehicle body comprises a vehicle main body, wherein the bottom structure of the vehicle main body forms a vehicle frame; the turbo shaft engine (1) is distributed between a front axle and a rear axle and is close to the vehicle frame of the rear axle; the axis of the output shaft of the turbo shaft engine (1) is positioned on the symmetry planes of the vehicle body; the air inlet of the turbo shaft engine (1) faces towards the tail of the vehicle; the gas inlet tank (12) is communicated with the air inlet of the turbo shaft engine (1); the gas inlet tank (12) is communicated with a gas inlet grille on a vehicle covering piece. The electric vehicle has the characteristics of high energy conversion efficiency, good operating performance, long driving mileage and high vehicle body structural strength.

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.
