Description

Technical Field

[0001] The utility model relates to the technical field of pressurized vehicles in plateau areas, and in particular to a manned pressurized vehicle suitable for long-distance movement in plateau areas. Background Art

[0002] With economic and social development, the market for self-driving tours and business trips in plateau areas is growing. For business travelers new to the plateau, altitude sickness, including dizziness, nausea, vomiting, and even decreased cardiopulmonary function, is highly susceptible. Currently, for mild cases of altitude sickness, short-term emergency measures such as handheld oxygen cylinders and oxygen concentrators for diffuse oxygen supply are the primary means of relief. For severe cases, hyperbaric oxygen chambers and pressurized ambulances are required for emergency treatment and rapid transport, ensuring the health and safety of those in the plateau.

[0003] Currently, most commonly used high-altitude pressurized medical ambulances are modified trucks, combining pressurization, oxygen supply, and other medical treatment functions. A typical example is a certain high-altitude pressurized medical ambulance, which utilizes a truck chassis and a container-type pressurized cabin. It primarily consists of a generator set, air pressurization system, oxygen supply and exhaust system, medical emergency system, and communication monitoring system. At altitudes of 5,000 meters, the air pressurization and oxygen supply system can create an interior environment similar to that of a vehicle below 3,000 meters, effectively addressing altitude sickness caused by initial exposure to the plateau.

[0004] Among them, methods such as handheld oxygen cylinders and oxygen concentrators are simple to operate. Although they can alleviate the symptoms of plateau hypoxia to a certain extent, they are difficult to improve the low pressure environment in which the patient is exposed, and therefore have no significant effect on the symptoms caused by low pressure. Hyperbaric oxygen chambers create a closed high-pressure environment, increase the oxygen concentration in the air, increase the oxygen content in the human body, promote blood circulation and the recovery of damaged cells, thereby alleviating the body's hypoxia. However, hyperbaric oxygen chambers are mainly used as medical treatment equipment. They occupy a large space, have a fixed installation location, and have a limited coverage area. They also have shortcomings such as single function and high cost, making them difficult to widely adopt. As a mobile medical rescue platform, the plateau pressurized medical ambulance has relatively complete functions and can provide reliable protection for the implementation of mobile medical rescue work in plateau areas. However, as a medical ambulance modified from a truck chassis, it still has the following shortcomings: the usage scenario is single, and it is mostly used for emergency treatment of special groups in hospitals and other places; the overall size and weight are large, the road conditions are high, and the vehicle maneuverability is poor; the driver must hold a B1 driver's license or above, and it cannot cover more ordinary people; the cost is high and the cost-effectiveness is insufficient; it uses a container-type pressurized cabin, the appearance is more industrial style, and the aesthetics are insufficient. Utility Model Content

[0005] In response to the above-mentioned defects of the existing technology, a manned booster vehicle suitable for long-distance movement in plateau areas is provided. It has the characteristics of safety and comfort, low driving requirements, beautiful appearance and moderate price. It is suitable for ordinary people, especially business travelers, to travel long distances in plateau areas.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] A manned pressurized vehicle suitable for long-distance movement in plateau areas is characterized by: comprising a chassis, a pressurized cabin, and a temperature and pressure control system; the chassis adopts a Class II chassis, with an independent cab provided in the front of the chassis and a carriage carried at the rear of the chassis; the pressurized cabin is fixedly connected in the carriage, and the front end of the pressurized cabin is fixedly connected to the rear end of the cab, and the two are not connected; the temperature and pressure control system is arranged in the Class II chassis and the carriage, and the temperature and pressure control system is connected to the pressurized cabin for adjusting the air pressure in the pressurized cabin; an airtight door is provided on the pressurized cabin for passengers to enter and exit the pressurized cabin.

[0008] According to the above technical solution, the temperature and pressure control system includes a boost branch composed of a boost fan and an intake pipe, a pressure relief branch composed of an exhaust pipe and an electric valve, a generator set and a storage battery for supplying energy to various equipment, and an on-board air conditioner for regulating the temperature inside the vehicle.

[0009] According to the above technical solution, the booster fan, on-board air conditioner, generator set and battery storage are all installed on the chassis and located directly below the vehicle compartment; among them, the booster fan, generator set and battery storage are located in front of the rear wheels, and the on-board air conditioner is located behind the rear wheels.

[0010] According to the above technical solution, the pressure relief branch also includes a spare exhaust pipe, and a manual ball valve is provided on the spare exhaust pipe.

[0011] According to the above technical solution, two booster fans are provided, which are symmetrically distributed along the length of the vehicle; one of the booster fans serves as a spare.

[0012] According to the above technical solution, an airtight door is provided between the cab and the pressurized cabin to connect the cab and the pressurized cabin; a transparent observation window is provided on the cabin door, and an intercom device is installed next to the transparent observation window.

[0013] According to the above technical solution, an airtight door is provided on one side of the pressurized cabin, a transparent observation window is provided on the airtight door between the cab and the pressurized cabin, and an intercom device is installed next to the transparent observation window.

[0014] According to the above technical solution, an airtight door is provided between the cab and the pressurized cabin, as well as on one side of the pressurized cabin; a transparent observation window is provided on the airtight door between the cab and the pressurized cabin, and an intercom device is installed next to the transparent observation window.

[0015] According to the above technical solution, airtight windows are provided on one or both sides of the pressurized cabin. The airtight windows are opened inward or outward. The airtight windows are hinged to the upper edge of the window frame, and the opening angle of the airtight windows is greater than 70°. A breakable area is also designed on the side of the airtight window, and is equipped with breaking tools.

[0016] According to the above technical solution, an arc-shaped cover is further provided between the carriage and the cab. The arc-shaped cover covers the top rear side of the cab and is connected to the front end of the carriage.

[0017] The utility model has the following beneficial effects:

[0018] This passenger-carrying pressurized vehicle utilizes a Class II chassis, with a pressurized cabin installed within the rear passenger compartment. The temperature and pressure control system is housed within the chassis and cabin, creating a separate pressurized space behind the Class II chassis for passengers. After passengers enter the pressurized cabin, they close the airtight door and activate the temperature and pressure control system, rapidly pressurizing the cabin to the set atmospheric pressure, providing a comfortable atmosphere for the passengers. As passengers near their destination, the temperature and pressure control system preemptively depressurizes the cabin, facilitating the opening of the airtight door upon arrival. During operation, the temperature and pressure control system provides real-time control of the cabin's temperature, pressure, and ventilation. Based on these measures, the pressurized cabin, constructed on a lightweight, high-load-bearing Class II chassis, offers a smaller overall size and weight compared to conventional truck-based multi-purpose pressurized vehicles that integrate pressurization, oxygen generation, and medical services. This results in improved maneuverability, lower driver requirements, and greater comfort. In addition, unlike other boosted oxygen supply medical vehicles, this boosted vehicle only provides a boosting function, which is more conducive to personnel operation and equipment stability, and can avoid safety risks such as explosion caused by oxygen supply. It is more suitable as a long-distance travel tool for ordinary people in plateau areas.

[0019] 2. By arranging the booster fan, onboard air conditioner, generator set, and battery storage along the side of the chassis, cabin space is maximized. Furthermore, the heavier booster fan, generator set, and battery storage are positioned ahead of the rear wheels, effectively balancing the vehicle's center of gravity. The generator set and supporting battery power the booster fan and other electromechanical equipment, ensuring stable operation. The onboard air conditioner, installed in the rear area of ​​the vehicle, regulates the cabin's internal temperature.

[0020] 3. When an emergency occurs, manually open the ball valve and the cabin will be depressurized quickly. After the depressurization is completed, the passengers can quickly escape through the airtight door or escape window.

[0021] 4. Two airtight doors are installed. The airtight door between the cab and the pressurized cabin is kept closed under normal circumstances, but can be used as an escape door in an emergency to facilitate the escape of passengers. An airtight door is installed on one side of the pressurized cabin, which is the normal door for passengers to enter and exit the pressurized cabin, and can also be used as an escape door in an emergency.

[0022] 5. The airtight window serves as both an observation window and an emergency escape window. It can be quickly broken using special breaking tools to quickly depressurize the pressurized cabin and provide conditions for the crew to escape quickly.

[0031] Reference Figures 1 and 2 As shown, the utility model provides a manned booster vehicle suitable for long-distance movement in plateau areas.

[0032] Example 1

[0033] It includes a chassis 1, a pressurized cabin 2, and a temperature and pressure control system; the chassis adopts a Class II chassis, with an independent cab 3 provided in the front of the chassis and a carriage 4 at the rear of the chassis; the pressurized cabin is fixedly connected in the carriage, and the front end of the pressurized cabin is fixedly connected to the rear end of the cab, and the two are not connected; the temperature and pressure control system is arranged in the Class II chassis and the carriage, and the temperature and pressure control system is connected to the pressurized cabin for adjusting the air pressure in the pressurized cabin; an airtight door 5 is provided on the pressurized cabin for passengers to enter and exit the pressurized cabin.

[0034] The pressurized cabin, serving as the primary passenger space, features a square main structure and is secured to the rear chassis using bolts and clips. Its length, width, and height are precisely aligned with the chassis. Constructed from a lightweight, high-strength aluminum alloy, it boasts a strong pressure-bearing capacity. The passenger compartment is mounted externally to the cabin, sealed with sealing strips at the interface with the chassis for excellent airtightness and protection from rain and dust. Its curved exterior offers a low drag coefficient, combining strength with aesthetics.

[0035] In this embodiment, the passenger-carrying pressurized vehicle utilizes a Class II chassis, with a pressurized cabin installed within the rear passenger compartment. The temperature and pressure control system is located within the chassis and the passenger compartment, creating an independent pressurized space behind the Class II chassis for passengers. After passengers enter the pressurized cabin, they close the airtight door and activate the temperature and pressure control system, rapidly pressurizing the cabin to the set atmospheric pressure, providing a comfortable air pressure environment for the passengers. As the passengers near their destination, the temperature and pressure control system preemptively depressurizes the cabin, facilitating the opening of the airtight door upon arrival. During operation, the temperature and pressure control system provides real-time control of the cabin's temperature, air pressure, and ventilation. Based on these measures, the pressurized cabin, constructed on a lightweight, high-load-bearing Class II chassis, offers a smaller overall size and lighter weight compared to conventional multi-purpose pressurized vehicles developed from truck chassis that integrate pressurization, oxygen generation, and medical services. This results in improved maneuverability and lower driver requirements. In addition, unlike other boosted oxygen supply medical vehicles, this boosted vehicle only provides a boosting function, which is more conducive to personnel operation and equipment stability, and can avoid safety risks such as explosion caused by oxygen supply. It is more suitable as a long-distance travel tool for ordinary people in plateau areas.

[0036] Example 2

[0037] The structure and principles of Example 2 are similar to those of Example 1, differing in that a preferred temperature and pressure control system structure is provided. The temperature and pressure control system includes at least a boost branch consisting of a boost blower 6 and an intake pipe 7, a pressure relief branch consisting of an exhaust pipe 8 and an electric valve 9, a generator set and battery 10 for powering various devices, and an onboard air conditioner 11 for regulating the vehicle's interior temperature. The temperature and pressure control system also includes various sensors, located inside or outside the vehicle. Using data detected by the sensors, the temperature and pressure control system adjusts the vehicle's interior pressure, temperature, and air circulation in real time.

[0038] In this embodiment, a booster fan and intake duct rapidly pressurize the pressurized cabin, creating an air pressure environment similar to that of low-altitude areas. The pressurized cabin is connected to the outside atmosphere via an exhaust duct and an electric valve. By controlling the opening time of the electric valve and coordinating the air intake from the booster fan, stale air inside the cabin can be regularly discharged, improving passenger comfort.

[0039] In Example 2, a preferred layout position of the various components of a preferred temperature and pressure control system is given, in which the booster fan, vehicle air conditioner, generator set and battery are all installed on the chassis and located directly below the vehicle compartment; among them, the booster fan, generator set and battery are located in front of the rear wheels, and the vehicle air conditioner is located behind the rear wheels.

[0040] In this embodiment, by arranging the booster fan, onboard air conditioner, generator set, and battery storage along the side of the chassis, passenger space is maximized. Furthermore, the heavier booster fan, generator set, and battery storage are positioned in front of the rear wheels, effectively balancing the vehicle's center of gravity. The generator set and accompanying battery power the booster fan and other electromechanical equipment, ensuring stable operation. The onboard air conditioner is installed in the rear area of ​​the vehicle to regulate the cabin's internal temperature.

[0041] Example 3

[0042] The structure and principle of Example 3 are similar to those of Example 2, except that the pressure relief branch also includes a backup exhaust pipe 12 equipped with a manual ball valve 13. In an emergency, manually opening the ball valve rapidly relieves cabin pressure, allowing occupants to escape quickly through the airtight door or escape window.

[0043] In embodiments 1-3, two booster fans are provided and symmetrically distributed along the length of the vehicle; one of the booster fans serves as a backup.

[0044] Example 4

[0045] The structure and principles of Example 4 are similar to those of any of Examples 1-3, differing in that an airtight door arrangement is provided between the driver's cab and the pressurized cabin, connecting the two. A transparent observation window is provided on the door, and an intercom is installed next to the window to facilitate communication between the driver and passengers. To cope with the high pressure within the pressurized cabin, the airtight door provides both high strength to prevent significant deformation and excellent sealing to prevent air leakage from the cabin.

[0046] Example 5

[0047] The structure and principle of Example 5 are similar to those of any of Examples 1-3, differing in that an alternative arrangement of airtight doors is provided: an airtight door is provided on one side of the pressurized cabin, and a transparent observation window is provided on the airtight door between the cab and the pressurized cabin. An intercom device 17 is installed next to the transparent observation window. To cope with the high pressure within the pressurized cabin, the airtight door has both high strength to prevent significant deformation and good sealing to prevent air leakage from the pressurized cabin.

[0048] Example 6

[0049] The structure and principle of Example 6 are similar to those of any of Examples 1-3, differing in that a third arrangement of airtight doors is provided: one airtight door is provided between the driver's cab and the pressurized cabin, and one airtight door is provided on one side of the pressurized cabin. A transparent observation window 14 is provided on the airtight door between the driver's cab and the pressurized cabin, and an intercom device is installed next to the transparent observation window. To cope with the high pressure within the pressurized cabin, the airtight door has both high strength to prevent significant deformation and good sealing to prevent air leakage from the pressurized cabin.

[0050] In this embodiment, the airtight door between the cab and the pressurized cabin remains closed under normal circumstances, but can be used as an escape door in an emergency to facilitate evacuation. An airtight door is provided on one side of the pressurized cabin, which is the normal door for passengers to enter and exit the cabin, and can also be used as an escape door in an emergency.

[0051] In Examples 1-6, airtight windows 15 are provided on one or both sides of the pressurized cabin. These windows open inward or outward, are hinged to the upper edge of the window frame, and have an opening angle greater than 70°. Fragmentable areas are also designed on the sides of the windows, and equipped with a breaking tool. These windows serve as both observation windows and emergency escape hatches. Using specialized breaking tools, they can be quickly broken, allowing for rapid decompression of the pressurized cabin and enabling occupants to escape quickly.

[0052] In Examples 1-6, a curved cover 16 is provided between the vehicle body and the cab. This curved cover covers the top rear side of the cab and connects to the front end of the vehicle body. Mounted on the roof, this curved cover serves as a transition between the front and the vehicle body, reducing wind resistance and enhancing the overall aesthetics.

[0053] Principle of this utility model:

[0054] During normal operation, passengers enter the pressurized cabin through the airtight door. Once the door is closed, the booster fan begins pressurizing the cabin, reaching the set pressure within minutes, creating a comfortable low-altitude environment. While the vehicle is in motion, the electric valve on the exhaust pipe automatically adjusts its opening time and opening range based on data from various air sensors within the vehicle. This, in conjunction with the booster fan, circulates and refreshes the air within the cabin. Before arriving at the destination, the electric valve is opened to its maximum opening to begin depressurizing the cabin. Once the cabin pressure drops to the same level as the outside pressure, the airtight door can be opened and the vehicle can be exited. In an emergency, the electric valve can be opened to its maximum opening and the manual ball valve can be opened simultaneously to rapidly depressurize the cabin. If the valve fails, the vehicle can use the provided window-breaking tool to shatter the weak points of the airtight windows. Once the cabin pressure drops to a sufficient level, the two front airtight doors or the side windows can be immediately opened for escape.

[0055] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
