Abstract

The invention discloses a three-gas cylinder fixed frame based on a hydrogen fuel cell urban bus, which comprises a fixed frame base assembly (1) and a circular hoop assembly (3); a fixed mounting beam assembly (6) is arranged on a lower cross beam (13) of the fixed frame base assembly (1), and the fixed mounting beam assembly (6) is of a hollow frame structure with a semicircular top end and a built-in reinforcing plate; a rectangular tube upper fixed part (11) is arranged on the lower cross beam (13); the fixed frame base assembly (1) is mounted at the top end of the rear part of a bus through a rectangular tube upper fixed part (11); a hoisting support (7) is also arranged on the lower cross beam (13); the fixed mounting beam assembly (6) and the lower cross beam (13) are directly welded into a whole through carbon dioxide arc welding, and a hydrogen cylinder is placed on an upper arc-shaped part (15) of the fixed mounting beam assembly (6) and then is connected and fixed through the hoop assembly. The overall design height is greatly reduced compared with a common structure, the structure is compact, installation is convenient, installation and fixation are firm, and later maintenance is convenient.

Description

technical field [0001] The invention belongs to the technical field of new energy buses, and in particular relates to a hydrogen bottle fixing frame structure of a hydrogen fuel cell city bus. Background technique [0002] Hydrogen fuel cell vehicles refer to vehicles powered by hydrogen as energy. Whereas internal combustion engines are usually injected with diesel or gasoline, hydrogen cars use gaseous hydrogen instead. The fuel cell and the electric motor replace the general engine, that is, the principle of the hydrogen fuel cell is to input hydrogen into the fuel cell, and the electrons of the hydrogen atoms are blocked by the proton exchange membrane, and are conducted from the negative electrode to the positive electrode through an external circuit to become electric energy to drive the electric motor; however, protons can It is combined with oxygen through the proton exchange membrane to form pure water mist and discharged. [0003] Hydrogen fuel cell city buses us...
