Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen energy logistics vehicles, and specifically relates to a hydrogen energy integrated frame for a hydrogen energy logistics vehicle. Background Technique

[0002] Hydrogen energy logistics vehicles have the advantage of zero emissions during operation. Hydrogen energy logistics vehicles use hydrogen fuel cells, and the product during the working process is water, which can achieve zero emissions during operation, so it will not cause environmental pollution. In recent years, the application of hydrogen energy logistics vehicles in logistics transportation has become more and more extensive, and more and more enterprises have begun to pay attention to the application of hydrogen energy logistics vehicles. Since 2023, with the efforts of various enterprises and battery operators, the development trend of hydrogen energy logistics vehicles has become increasingly popular, and order contracts for the delivery of hundreds of vehicles have continuously emerged. Generally speaking, future applications will become more and more mature, and product demand will be more and more. Currently, the hydrogen energy logistics vehicles on the market are mainly 4.5T and 18T commercial vehicles, and most of the hydrogen fuel systems also adopt the integrated frame method.

[0003] For example, a vehicle-mounted hydrogen supply system frame for a hydrogen fuel logistics vehicle disclosed in the publication number CN215552585U installs a hydrogen storage cylinder installation frame on the power assembly installation frame. When it is necessary to add a hydrogen storage cylinder, the top plate can be supported by using a clamping component and a support rod, which is convenient for placing the hydrogen storage cylinder. There is no need to use bolts, etc. to install the hydrogen storage cylinder installation frame on the power assembly installation frame, which is more convenient to use. Another example is a vehicle-mounted hydrogen supply system frame for a hydrogen fuel logistics vehicle disclosed in the publication number CN211764967U, which can greatly reduce the total weight of the vehicle-mounted hydrogen supply system. At the same time, the installation space of the hydrogen supply system is integrally distributed in an "L" shape, which can reduce the height space required by the vehicle-mounted hydrogen supply system, so that the height of the installation space of the hydrogen supply system is reduced to about 45% of the height of the vehicle-mounted hydrogen supply system frame. At the same time, the center of gravity of the vehicle-mounted hydrogen supply system is effectively reduced, enhancing stability; in addition, at the same time, a vehicle-mounted hydrogen storage cylinder installation position is reserved at the top of the frame body. If the vehicle needs a longer mileage, a fourth vehicle-mounted hydrogen storage cylinder can be installed at the vehicle-mounted hydrogen storage cylinder installation position at the top to achieve the hydrogen supply capacity of a four-bottle group hydrogen system, thereby effectively increasing the hydrogen fuel storage capacity and improving the cruising range.

[0004] However, at present, the hydrogen energy system of hydrogen energy logistics vehicles on the market mainly consists of high-pressure hydrogen storage cylinders for hydrogen fuel, compressors, air filters, radiators, water pumps, and electrical box water storage tanks, etc. At present, the development of the main models is carried out on the basis of the original electric vehicles and fuel vehicles.
