Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-altitude pressurized vehicle technology, specifically to a high-altitude passenger pressurized carriage and passenger pressurized vehicle. Background Technology
[0002] With my country's economic and social development, the number of people traveling to the Qinghai-Tibet Plateau for work and other purposes has increased. People newly arriving at the plateau are highly susceptible to short-term altitude sickness, such as dizziness, nausea, and vomiting. Currently, for mild altitude sickness, emergency methods such as handheld oxygen supply, diffused oxygen supply, and hyperbaric oxygen chambers are mainly used to alleviate the symptoms. To facilitate emergency treatment and rapid transportation, pressurized medical ambulances have also been developed. These devices and methods safeguard the lives and health of people entering the plateau region.
[0003] While handheld oxygen cylinders and diffused oxygen supply from oxygen concentrators are simple to operate, they are insufficient to address altitude sickness caused by low-pressure environments. Hyperbaric oxygen chambers can simultaneously address both hypoxia and low pressure in high-altitude environments, but as medical equipment, they occupy a large space, have fixed installation locations, and are expensive. High-altitude pressurized medical ambulances, as mobile medical rescue platforms, combine pressurization, oxygen supplementation, and medical treatment functions, providing reliable support for mobile medical rescue operations in high-altitude areas.
[0004] Currently, most commonly used high-altitude pressurized vehicles are modified trucks, using truck chassis and container-type pressurized cabins. These vehicles still have the following shortcomings: large size and weight, requiring high-quality road conditions; complex operation, demanding skilled drivers, making them unsuitable for the general population; aesthetically unappealing container-type pressurized cabins; limited application scenarios, primarily emergency care in hospitals and other special settings, resulting in a single purpose, high cost, and poor cost-effectiveness. Summary of the Invention
[0005] The purpose of this utility model is to provide a pressurized passenger carriage for high-altitude areas, which can be installed on a regular Class II chassis. It features good overall integrity, small size, light weight, good handling performance, better passenger comfort, lower driving requirements, and easy and quick installation, disassembly and maintenance. It is suitable for ordinary business travelers in high-altitude areas.
[0006] The technical solution adopted in this utility model is:
[0007] A pressurized passenger compartment for high-altitude travel includes a pressurized chassis and a pressurized compartment body. The internal cavity of the pressurized compartment body is divided into a pressurized area and a non-pressurized area. The pressurized area is used as a pressurized activity space for passengers to rest, and the non-pressurized area is used to install environmental control equipment. The pressurized compartment body is connected to the pressurized chassis via a conversion frame for fixing the pressurized compartment body.

[0019] The front end of the pressurized compartment is not connected to the rear end of the cab of the Class II chassis. A transparent and airtight communication window is provided between the cab of the Class II chassis and the pressurized compartment for communication between the cab and the pressurized compartment.
[0020] The beneficial effects of this utility model are:
[0021] 1. This utility model uses a conversion frame to mount the compartment on the chassis. The pressurized compartment is divided into a pressurized area and a non-pressurized area.

[0031] Example 2
[0032] Based on Example 1, the environmental control equipment of the compartment is further restricted, resulting in Example 2 having even better performance.
[0033] The environmental control equipment for the compartment includes a compressor 14, an air conditioner 15 for regulating the temperature inside the compartment, a power generation system for supplying power to the compartment equipment, and a control system.
[0034] The pressurization zone 6 pressurizes the compartment through the compressor 14, the air intake channel, and the air intake valve 11; the pressurization zone 6 depressurizes the compartment through the electric exhaust valve 12 and / or the manual exhaust valve 13.

[0040] Furthermore, an airtight door for personnel to enter and exit is provided on one side of the pressurized chamber. The airtight door 9 is equipped with a transparent observation window 10 for personnel to enter and exit the pressurized area and observe.
[0041] Furthermore, an airtight window 8 is provided on one or both sides of the pressurized compartment; a fragile area is designed on the side of the airtight window 8 and equipped with a tool hammer; the airtight window 8 and the communication window 17 are provided for both observation and emergency escape. Under normal use, they are kept sealed. In an emergency, the tool hammer can be used to break the window to quickly depressurize the pressurized compartment and facilitate the evacuation of passengers.
[0042] The turbocharged vehicle chassis is a Class II chassis.
[0043] The pressurized compartment 6 and the non-pressurized compartment 7 are respectively located at the front and rear ends of the pressurized compartment, with the front end of the pressurized compartment being located close to the driver's cab.
[0044] The front end of the pressurized compartment is not connected to the rear end of the cab of the Class II chassis 1. A transparent and airtight communication window 17 is provided between the cab of the Class II chassis 1 and the pressurized compartment for communication between the cab and the pressurized compartment.
[0045] Furthermore, an arc-shaped cover 4 is provided between the pressurized car body and the cab 3. The arc-shaped cover 4 covers the rear top of the cab 3 and is connected to the upper front end of the pressurized car body.
[0046] The working principle of this utility model is as follows: A fixed conversion frame 5 is installed on the chassis frame 2, and the pressurized compartment is fixed to the chassis frame 2 using the conversion frame 5. The length, width, and height are all adapted to the chassis, and the material is lightweight and high-strength aluminum alloy or fiberglass, giving it a strong overall pressure-bearing capacity. The pressurized compartment is divided into a pressurized area 6 and a non-pressurized area 7. The pressurized area 6 is the space for personnel activities, and the non-pressurized area 7 is used to place or install environmental control equipment. The pressurized area 6 of the pressurized compartment is equipped with an airtight window 8, an airtight door 9, and a communication window 17. The airtight door 9 is used for personnel entry and exit, and the airtight window 8 is used for observing the outside scenery. The communication window 17 is used to observe the front of the vehicle and communicate with the driver; an observation window 10 can be opened on the airtight door 9 for observing the outside view; the pressurized compartment is not connected to the cab 3; the cab 3 is designed with a streamlined arc-shaped cover 4 above it, forming an integral part with the pressurized compartment; the environmental control equipment in the non-pressurized area 7 of the compartment includes a compressor 14, an air conditioner 15, a generator set and a battery 16, as well as other necessary equipment; the environmental control equipment is connected to the pressurized area 6 of the pressurized compartment through pipelines such as an intake valve 11, an electric exhaust valve 12, and a manual exhaust valve 13 to regulate the air pressure and temperature inside the pressurized compartment.
[0047] In this embodiment, the high-altitude passenger pressurized compartment is installed on a standard Class II chassis. After the occupants enter the pressurized compartment, they close the airtight door 9 and activate the environmental control equipment to quickly pressurize the pressurization zone 6 of the compartment to the set atmospheric pressure, providing a comfortable air pressure environment for the occupants. During vehicle operation, the environmental control equipment uses a control system to monitor the temperature, air pressure, and ventilation of the pressurization zone 6 in real time to ensure environmental comfort. When the occupants are about to reach their destination, the environmental control equipment depressurizes the pressurized compartment to the destination's air pressure level, facilitating the opening of the airtight door upon arrival. Compared to pressurized oxygen compartments developed from towed and tractor-mounted chassis, this compartment is directly fixed to a Class II chassis, resulting in better overall integrity, smaller size, lighter weight, better handling performance, superior passenger comfort, and lower driving requirements for the driver. In addition, this compartment completely isolates the driver's cab and the passenger compartment, separating driving and pressurization operations, reducing the difficulty of operation for personnel, facilitating quick installation, disassembly and maintenance of the compartment, and making it more suitable for large-scale production in vehicle factories and large-scale use by the general public in high-altitude areas.
[0048] During normal use, occupants enter the pressurized compartment through the airtight door. After closing the door, the compressor begins pressurization, reaching the set pressure within minutes to create a comfortable environment. While the vehicle is in motion, the electric exhaust valve and compressor automatically adjust based on data from various air sensors inside the vehicle to refresh the air inside the compartment. Before reaching the destination, the electric exhaust valve is opened in advance to depressurize the pressurized compartment. Once the compartment pressure drops to match the outside pressure, the airtight door can be opened to exit the pressurized compartment. In case of emergency, the manual exhaust valve can be opened to depressurize the compartment as quickly as possible. If the valve malfunctions, a hammer provided with the vehicle can be used to break the weak points of the airtight window. Once the compartment pressure drops to a certain level, the airtight door or window can be opened for escape.
