Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydrogen storage equipment, in particular to a carbon fiber hydrogen bottle for a vehicle. Background Art
[0002] At present, hydrogen energy is considered to be the ultimate energy source for automobiles due to its zero emission characteristics. With the rapid development and industrialization of hydrogen fuel cells and electric vehicles, the current automotive hydrogen storage technology is high-pressure hydrogen storage in hydrogen storage cylinders. Hydrogen storage cylinders generally include four types: Type I bottles are made of all steel. The main disadvantage is that they are heavy and not suitable for vehicle-mounted use. They are mostly placed in hydrogen refueling stations as fixed hydrogen storage; Type II and Type III bottles have metal inner liners wrapped with carbon fiber, which are also relatively heavy, but lighter than Type I bottles; Type IV bottles have plastic inner liners fully wrapped with carbon fiber, which are the lightest and suitable for vehicle-mounted use. They are the mainstream technical route at home and abroad, but they are still heavy and the manufacturing process is relatively complicated.
[0003] The authorization publication number "CN218720592U" records "a carbon fiber hydrogen bottle for a vehicle, comprising a bottle body, the bottle body comprising a metal bottle mouth and a carbon fiber reinforced shell, the metal bottle mouth is arranged on the top of the carbon fiber reinforced shell, and specifically, after the metal bottle mouth is pressed, the metal bottle mouth can be directly sleeved on the processing rod, and then a mold made according to the preset shape of the bottle body is buckled on the periphery of the metal bottle mouth, and then the inside of the mold is filled with clay by clay modeling. After the clay is air-dried, the mold is removed to form a clay bottle body under the metal bottle mouth, and then the clay bottle body is wrapped with carbon fiber cloth to form a carbon fiber layer, and a reinforcement layer is formed on the carbon fiber layer by a vacuum introduction process. The reinforcement layer can be composed of resin, that is, the resin layer and the carbon fiber layer constitute a carbon fiber reinforced shell; while ensuring light weight, pressure resistance is guaranteed, and the overall manufacturing process is simpler and easier to produce".
[0004] The above patent can ensure both light weight and pressure resistance. The overall manufacturing process is simpler and easier to produce. However, in reality, the liquid hydrogen inside the bottle will shake violently during transportation, thus affecting the internal stability. Utility Model Content
