The invention relates to a vehicle-mounted hyperbaric cabin which creates a high-pressure environment in a vehicle. People who live in the
plateau for a long time have altitude stress when traveling on the
plateau, in order to solve the altitude
stress problem, a vehicle-mounted high-pressure space is provided for people, the air pressure in the vehicle-mounted high-pressure cabin is higher than that of the external space, a
space environment close to the pressure of the
plateau is created on the plateau, and the air pressure of the vehicle-mounted high-pressure cabin is higher than that of the external space. The altitude stress can be relieved. And the air pressure in the vehicle-mounted hyperbaric cabin can be gradually reduced according to the
adaptation condition of a user, so that the vehicle-mounted hyperbaric cabin adapts to the external environment. For severe altitude stress, an
oxygen bottle can be carried into the vehicle-mounted hyperbaric cabin for
oxygen inhalation, so that the altitude stress condition can be relieved as soon as possible. According to the technical scheme, after a user enters a cabin body, an air pressurization
system is opened, external air is pressurized after being filtered, the pressurized air continuously enters the vehicle-mounted hyperbaric cabin from the upper portion, and when the air pressure in the cabin reaches the set air pressure,
overpressure air is exhausted from the lower portion through an automatic pressure
exhaust valve; therefore, the air pressure in the cabin is stable.
