Overhead hydrogen storage device of fuel cell truck

Technical Field

The utility model is not suitable for a fuel cell cargo vehicle is with storing up hydrogen device, concretely relates to fuel cell cargo vehicle overhead type stores up hydrogen device.

Background

With the use of a large amount of petroleum energy, the pollution problem caused by exhaust emission of the traditional internal combustion engine vehicle is increasingly prominent in the use process, and pollutants such as NOx, PM and the like seriously influence the life and health of people. In order to solve the problem of emission pollution, new energy vehicles are vigorously developed all over the world, and mainly include pure electric, plug-in hybrid and fuel cell powered vehicles. Among them, the hydrogen fuel cell vehicle is one of the technologies that has the most promising application prospect and can completely replace the conventional internal combustion engine vehicle. The fuel cell is a power device of the vehicle, provides electric energy for the whole vehicle, is an energy conversion device and needs to be supplemented with fuel continuously. Hydrogen fuel cell vehicles use hydrogen as a fuel and the vehicles continuously consume the electrical energy converted from hydrogen during use. The driving habit of the hydrogen fuel cell automobile is basically consistent with that of the traditional fuel oil vehicle, and the use feeling of a user is less changed. The cruising ability of the vehicle is closely related to the amount of fuel stored on the vehicle.

The hydrogen fuel cell vehicle needs to store certain hydrogen according to different vehicle types and different use scenes, and the hydrogen storage needs to occupy larger vehicle space due to the fact that the volume density of the hydrogen is relatively small. Whether the passenger vehicle is compact in space or the commercial vehicle is slightly large in space, the requirement on the space for storing hydrogen is high, different problems can be brought to users by reducing the using space of the whole vehicle, and therefore the reasonable arrangement of the hydrogen storage container is one of the key fields of whole vehicle development.

At present, on hydrogen fuel cell commercial vehicle, adopt many gas cylinders mode usually, light-duty commodity circulation car that carries adopts 2 ~ 3 gas cylinders, and the gas cylinder is installed on the gas cylinder frame, generally wholly arranges at the driver's cabin rear. The commonly used gas cylinder is a carbon fiber winding cylinder with an aluminum inner container and the pressure of 35MPa and the volume of 140 liters. The gas cylinder on the commodity circulation car is arranged and can occupy certain packing box space behind the driver's cabin, reduces user's the transportation space of carrying goods, causes the decline of conveying efficiency, the increase of cost of transportation.

Disclosure of Invention

In order to solve the above-mentioned problem of prior art, the utility model provides a fuel cell cargo truck overhead type hydrogen storage device passes through the configuration of arranging of design optimization hydrogen storage cylinder to fuel cell cargo truck, can effectively utilize the packing box space, improves the utilization ratio of vehicle packing box, improves the security of whole car, and the unpicking and examining of gas cylinder, maintenance are also more convenient.

The utility model provides a fuel cell cargo truck overhead type hydrogen storage device, carriage top boxboard processing has a plurality of fixed slots, fixes hydrogen storage cylinder with the strap at carriage top and 1 part embedding fixed slots of hydrogen storage cylinder, is equipped with shockproof liner between hydrogen storage cylinder and the fixed slot, and hydrogen storage cylinder upper portion uses the protection casing to cover, connects through gas cylinder connecting line between a plurality of hydrogen storage cylinder.

And ventilation structures are arranged at the top and the side of the protective cover.

And the hydrogen storage cylinder is also provided with a shockproof rubber ring.

The hydrogen storage device is arranged at the top of the container, thereby not only taking the utilization rate of the container into account, but also being beneficial to the removal of hydrogen, and ensuring the safety of vehicle-mounted hydrogen; the gas cylinder and the carriage are integrally combined, the hydrogen cylinder is embedded into one part of the carriage of the truck, the occupation proportion of a cargo box of the truck is greatly reduced, and the embedded structure is very effective in preventing the hydrogen cylinder from being moved along the axial direction in an arrangement mode the same as the driving direction of the truck.

Detailed Description

The technical scheme of the utility model is described in detail with the accompanying drawings and the embodiment as follows:

the hydrogen storage cylinder is combined with the logistics carriage, the hydrogen storage cylinder is arranged at the top of the carriage, one part of the hydrogen storage cylinder is embedded in the space of a box plate at the top of the carriage, and the part of the hydrogen storage cylinder, which is not in contact with the box plate at the top of the carriage, the opening of the hydrogen storage cylinder, an air guide pipeline and the like are exposed to the environment at the top of the vehicle. The contact part between the top of the carriage and the gas cylinder is completely sealed.

As shown in fig. 1 to 4, a top-mounted hydrogen storage device for a fuel cell truck, a box plate 5 at the top of a carriage is provided with a plurality of fixing grooves 6 according to the shape of a hydrogen storage cylinder 1, the commercially available hydrogen storage cylinder 1 is fixed at the top of the carriage by a strap and is partially embedded into the fixing grooves, the diameter of the commercially available hydrogen storage cylinder is D, the diameter of the box plate fixing groove is the same as that of the cylinder, the arc length is less than 1/2 pi D, a shockproof liner 4 is arranged between the bottom of the hydrogen storage cylinder 1 and the fixing grooves 6, the upper part of the hydrogen storage cylinder 1 is covered by a protective cover 7, and the hydrogen storage cylinders 1 are connected by stainless steel cylinder connecting.
