Front-engine rear-drive hydrogen energy automobile whole-vehicle framework and hydrogen energy automobile

Abstract

The invention provides a front-engine rear-drive hydrogen energy automobile whole-vehicle framework and a hydrogen energy automobile. The front-engine rear-drive hydrogen energy automobile whole-vehicle framework comprises a whole-vehicle platform, a hydrogen cylinder frame, a hydrogen energy engine and a driving system, the hydrogen cylinder frame is fixed to the bottom of a floor of the whole-vehicle platform, and a hydrogen cylinder set is fixed to the hydrogen cylinder frame; the hydrogen energy engine is fixed to the front portion of the whole vehicle platform and located in front of the hydrogen cylinder frame; and the driving system is fixed to the rear portion of the whole-vehicle platform and located behind the hydrogen bottle frame. The technical scheme provided by the invention has the beneficial effects that the whole vehicle adopts a front-engine rear-drive form, and front and rear axle load distribution is reasonable. The hydrogen cylinder set is arranged in the area below the floor, hydrogen cylinders are far away from the front and rear ends of the vehicle, impact force cannot be transmitted to the hydrogen cylinder frame when the vehicle collides in the front-back direction, meanwhile, a large amount of crumple space can be provided for protecting the hydrogen cylinder group from being damaged, and safety performance is improved. Space below the floor is completely used for storing hydrogen, the space utilization rate of the vehicle can be improved, and therefore the vehicle can run for a long time.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy vehicles, in particular to a front-rear drive hydrogen energy vehicle vehicle structure and a hydrogen energy vehicle. Background technique [0002] At present, hydrogen energy vehicles are mostly adjusted on the basis of fuel vehicle platforms, and there are many disadvantages in the form of integrated layout. Some vehicles carry three hydrogen bottles, which are respectively arranged in the middle passage area, under the rear seats and in the area behind the rear axle. At least the following disadvantages will be brought about: [0003] 1. There is not enough space in the Y direction of the car, and the middle aisle protrudes higher into the car and has a larger width, which makes the space in the Y direction relatively small, and only 2 people can be seated in the rear row; [0004] 2. There is insufficient space above the head of the passenger, and hydrogen bottles are arranged under ...

AI Technical Summary

Problems solved by technology

[0003] 1. There is not enough space in the Y direction of the car, and the middle aisle protrudes higher into the car and has a larger width, which makes the space in the Y direction relatively small, and only 2 people can be seated in the rear row;

[0004] 2. There is insufficient space above the head of the passenger, and hydrogen bottles are arranged under the rear seat, which causes the rear seat to be raised in the Z direction, which limits the head space of the rear passenger;

[0005] 3. The safety is poor. The hydrogen bottle arranged in the rear area of ​​the rear axle has a small space away from the rear end of the vehicle. It is easy to damage the hydrogen bottle in the event of a collision, which brings potential safety hazards;

[0006] 4. The equipment is backward and the comfort is poor. The rear suspension adopts torsion beam non-independent suspension, and other models of this level basically use independent suspension
