Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be further described with reference to the accompanying drawings.

The invention provides a hydrogen energy automobile which comprises a front-mounted rear-mounted hydrogen energy automobile whole-automobile framework, and the hydrogen energy automobile with the front-mounted rear-mounted hydrogen energy automobile whole-automobile framework belongs to the hydrogen energy automobile. The invention has the innovation point of the front-engine and rear-engine hydrogen energy automobile complete vehicle framework, and the front-engine and rear-engine hydrogen energy automobile complete vehicle framework is described in detail below.

Referring to fig. 1 to 5, an embodiment of the invention provides a front-engine and rear-engine hydrogen energy vehicle structure, which includes a vehicle platform 1, a hydrogen cylinder frame 2, a hydrogen energy engine 4, and a driving system 5.

The hydrogen bottle frame 2 is fixed at the bottom of the floor of the whole vehicle platform 1, the hydrogen bottle frame 2 is used for fixing the hydrogen bottle group 3, and specifically, the hydrogen bottle frame 2 is riveted with a vehicle body cross beam and a vehicle body longitudinal beam 11 of the whole vehicle platform 1; the hydrogen energy engine 4 is fixed at the front part of the whole vehicle platform 1 and is positioned in front of the hydrogen cylinder frame 2; and the driving system 5 is fixed at the rear part of the whole vehicle platform 1 and is positioned behind the hydrogen cylinder frame 2.

By the arrangement, the whole vehicle adopts a front-mounted rear-drive mode, and the front and rear axle loads are reasonably distributed. The hydrogen bottle group 3 is arranged in the area below the floor, the hydrogen bottle is far away from the front end and the rear end of the vehicle, when the vehicle collides in the front and rear direction, the impact force can not be transmitted to the hydrogen bottle frame 2, meanwhile, a large amount of crumple spaces can be arranged to protect the hydrogen bottle group 3 from being damaged, and the safety performance is improved. The space below the floor is completely used for storing hydrogen, so that the space utilization rate of the vehicle can be improved, and the ultra-long endurance of the vehicle is realized. For example, the hydrogen carrying capacity of the new generation Toyota MIRAI is about 5kg, in the technical scheme provided by the invention, the length of the vehicle is 1100mm shorter than that of the Toyota MIRAI vehicle, the hydrogen carrying capacity can reach 6.5kg, and the overlarge hydrogen carrying capacity is the guarantee of endurance. Along with the perfect overall arrangement of later stage hydrogenation station, reducible hydrogen bottle quantity, hydrogen bottle group 3 arranges on hydrogen bottle frame 2, and hydrogen bottle frame 2 is installed in the floor below again, is convenient for adjust the hydrogen bottle quantity on the hydrogen bottle frame 2 in a flexible way, and the adjustment is simple, both can reduce vehicle weight, also can reduce cost by a wide margin. The hydrogen bottles are arranged on the hydrogen bottle frame 2 in parallel and can be arranged along the transverse direction or the longitudinal direction of the vehicle, when the number of the hydrogen bottle groups 3 is symmetrically reduced, the influence on the front and rear axle loads is balanced, the posture change of the whole vehicle is small, and the cost of the whole vehicle is reduced. Arrange in the automobile body with the hydrogen cylinder decentralization and compare, hydrogen cylinder group 3 is unified to be arranged on hydrogen cylinder frame 2, can improve the equilibrium of whole car framework, and the pipeline trend is simple, and hydrogen reveals that the monitoring area is little, and is with low costs, and the security is high to promote whole car performance.

If the hydrogen bottles are transversely arranged under the rear row of seats, the hydrogen storage amount is seriously insufficient, and the hydrogen storage can be maximized only by fully utilizing the area below the floor for hydrogen storage. After the maximum hydrogen storage scheme is determined, the hydrogen energy engine 4 is arranged in front, and the driving system 5 is arranged on the rear shaft, so that the arrangement requirement, the shaft load balance, the heat management performance and the pipeline trend of the hydrogen energy engine 4 in the space can be ensured. If the front drive is present, the cabin space is not sufficient. If the engine is arranged at the rear and at the front, the space at the rear part is not enough for arranging the hydrogen energy engine 4, and the space utilization rate is not high when the driving system 5 is arranged at the front cabin.

Further, the whole vehicle platform 1 comprises a cabin longitudinal beam 12, a trunk side beam 13 and a vehicle body longitudinal beam 11, the floor is fixed on the vehicle body longitudinal beam 11, specifically, the floor is made of an aluminum plate and is welded with the vehicle body longitudinal beam 11.

All system components such as the cabin longitudinal beam 12, the trunk side beam 13, the vehicle body longitudinal beam 11, the hydrogen bottle frame 2 and the like are made of aluminum profiles, and the connection modes are welding and riveting.

Referring to fig. 4 and 5, one end of the connecting casting 6 close to the vehicle body longitudinal beam 11 is bent to form a first bent portion 7, and the first bent portion 7 and the vehicle body longitudinal beam 11 are arranged in parallel and fixedly connected, so that the connecting casting 6 and the vehicle body longitudinal beam 11 can be conveniently installed. In this embodiment, the connection between the vehicle body side member 11 and the first bent portion 7 is a caulking connection.

The automobile body longitudinal beam 11 is close to cabin longitudinal beam 12 or the one end bending type of suitcase boundary beam 13 forms second kink 8, second kink 8 with cabin longitudinal beam 12 or suitcase boundary beam 13 is parallel arrangement and fixed connection, is convenient for connect the installation between foundry goods 6 and cabin longitudinal beam 12, the suitcase boundary beam 13. In this embodiment, the end of the second bending portion 8 is provided with an insertion groove 81, and the cabin longitudinal beam 12 or the trunk side beam 13 is inserted into the insertion groove 81, so that when the vehicle is impacted in the front-rear direction, the cabin longitudinal beam 12 and the trunk side beam 13 are always located in the insertion groove 81, the cabin longitudinal beam 12, the trunk side beam 13 and the vehicle body longitudinal beam 11 are prevented from moving in a staggered manner, and the safety performance of the vehicle can be improved. The cabin longitudinal beam 12 or the trunk side beam 13 and the second bent part 8 are connected in a riveting and gluing mode. After glue is applied to the insertion groove 81, the cabin longitudinal beam 12 or the trunk side beam 13 is inserted into the insertion groove 81, and then riveted and fixed, so that the connection strength can be enhanced.

Be equipped with on connecting foundry goods 6 and be the strengthening rib 61 of latticed setting, can increase the intensity of connecting foundry goods 6, avoid connecting foundry goods 6 and warp easily. The two connecting castings 6 positioned on the front side or the rear side of the vehicle body longitudinal beam 11 are fixedly connected through the connecting rod 9, so that the strength of the vehicle body impacted in the left-right direction can be enhanced. The connecting casting 6 is a casting part and is integrally formed, so that the strength of the connecting casting 6 can be increased.
