[0047] It is to be noted that, in the description of the specification, the description referring to the terms "embodiment", "one embodiment", and "one implementation" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or implementation are included in at least one embodiment or implementation of the present application. In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0048] In the description of the present application, unless otherwise explicitly defined, the words such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0049] In the case of no conflict, the above embodiments and features in the embodiments can be combined with each other.

[0050] Due to its special geographical environment and climate conditions, the atmospheric pressure is low and the air is thin in plateau areas. People living in the area for a long time will have symptoms of hypoxia, such as dizziness, fatigue, and difficulty breathing. In severe cases, it can also cause serious diseases such as high altitude pulmonary edema and high altitude cerebral edema.

[0051] At present, for patients with mild high altitude reaction, mainly short-term emergency methods such as handheld oxygen cylinder, oxygen generator dispersion oxygen supply are used to relieve. The operation of handheld oxygen cylinder oxygen supply and oxygen generator oxygen supply is simple, although it can relieve the symptoms of high altitude hypoxia to a certain extent, but it is difficult to improve the low pressure environment of the patient, so it has no obvious improvement effect on the symptoms caused by low pressure.

[0052] For patients with severe high altitude reaction, high pressure oxygen chamber and high altitude pressurized oxygen enrichment vehicle are needed to perform emergency treatment and safe transportation, so as to protect the physical health and life safety of people in plateau areas.

[0053] The high pressure oxygen chamber can effectively relieve the hypoxia state of the body by creating a closed high pressure environment, increasing the oxygen concentration in the air, and then increasing the blood oxygen content of the human body, promoting blood circulation and the recovery of damaged cells. However, the high pressure oxygen chamber is mainly used as a medical treatment equipment, which has the disadvantages of large overall space occupation, fixed installation position, limited protection range, single function, high cost, etc., and is difficult to popularize in a large range.

[0054] As a mobile recuperation platform, the plateau pressurized oxygen-enriched vehicle has complete functions and can provide reliable guarantee for long-distance movement in plateau areas. However, the commonly used plateau pressurized oxygen-enriched vehicle is mostly modified from a car chassis or a second-class chassis, and has the functions of pressurization, oxygen supplementation and other medical treatment. This modification limits the appearance design and internal layout of the cabin of the plateau pressurized oxygen-enriched vehicle due to the original chassis, which not only cannot maximize the use of space, but also has great difficulty in modification and insufficient aesthetics; in addition, only the passengers in the pressurized cabin are considered for recuperation, and the driver's cabin cannot be covered in real time.

[0055] To solve the above technical problems, please refer to Figures 1-2 、 Figure 7 、 Figure 8 The embodiment of the present application provides a manned pressurized vehicle, which comprises a vehicle chassis assembly 3, a pressure-bearing closed structure 4 arranged on the vehicle chassis assembly 3 and a pressurization system 9.

[0056] The pressure-bearing closed structure 4 comprises a first support structure 41, a flexible pressure-bearing component and a second support structure 43; the first support structure 41 is arranged outside the second support structure 43; there is a spacing space between the first support structure 41 and the second support structure 43; the flexible pressure-bearing component is arranged in the spacing space; the pressure-bearing closed structure 4 is used to form a closed pressurized space 6 on the vehicle chassis assembly 3; the pressurization system 9 is used to communicate with the closed pressurized space 6 and to control the pressurization of the closed pressurized space 6; the first support structure 41 is used to limit the expansion of the flexible pressure-bearing component when the flexible pressure-bearing component is pressurized; and the second support structure 43 is used to support the flexible pressure-bearing component when the flexible pressure-bearing component is under normal pressure.

[0057] In the embodiment of the present application, the manned pressurized vehicle is composed of a vehicle chassis assembly 3, a pressure-bearing closed structure 4 and a pressurization system 9, wherein the vehicle chassis assembly 3 is composed of a vehicle frame, cooperatively arranged wheels, a driving device, a power generation device and the like; the pressure-bearing closed structure 4 is installed on the upper surface of the vehicle chassis assembly 3; and the pressurization system 9 is installed at the bottom of the vehicle chassis assembly 3.

Since the flexible pressure-bearing component is between the first support structure 41 and the second support structure 43, and the volume of the flexible pressure-bearing component will expand under pressurization and will shrink under normal pressure, the first support structure 41 limits the expansion of the flexible pressure-bearing component when the flexible pressure-bearing component is pressurized, and the second support structure 43 supports the flexible pressure-bearing component when the flexible pressure-bearing component is under normal pressure.

When it is needed to increase oxygen pressure in the closed pressurization space 6, oxygen is supplied to the closed pressurization space 6 through the pressurization system 9, so that the flexible pressure-bearing component gradually expands and becomes larger, and the first support structure 41 is arranged outside the flexible pressure-bearing component, and the first support structure 41 serves as the outer support of the flexible pressure-bearing component. When it is not needed to increase oxygen pressure in the closed pressurization space 6, the second support structure 43 is located inside the flexible pressure-bearing component, and the second support structure 43 also serves as the inner support of the flexible pressure-bearing component. The pressure-bearing closed structure 4 can be applied to different types of chassis, the modification process meets the requirements of manned vehicles, has the objective conditions of manned commercial vehicles, and has less influence on the safety of the whole vehicle; on the basis of controlling the weight of the whole vehicle, the vehicle standard and requirements of commercial vehicles and the like are met; the high-altitude travel problem of plateau travel people in daily travel is solved, and the life quality and tourism experience in high-altitude areas are greatly improved.

Therefore, a closed space is formed between the flexible pressure-bearing part and the upper surface of the vehicle chassis assembly 3, which is the closed pressurized space 6 described above.

[0072] It should be particularly pointed out that the above-mentioned one embodiment, another embodiment and still another embodiment involve different types of the vehicle chassis assembly 3, and the definition of the type of the vehicle chassis is as follows:

[0073] The first type of chassis: that is, the first type of vehicle, which is a complete vehicle including all systems of the vehicle, that is, the most common type of vehicle;

[0074] The second type of chassis: that is, the second type of vehicle, which is a vehicle lacking a vehicle cabin, having a cab, an operating system, a steering system, a braking system, a transmission system, etc.

[0075] Three types of chassis: namely three types of car, is lack of cab, carriage, front plate parts of the car, with engine, gearbox, transmission, front and rear axle, brake system and other components, but the vehicle can not travel.

[0076] Further, please refer to Figure 2 As shown in the first support structure 41 and the second support structure 43 are fixed on the vehicle chassis assembly 3, the flexible pressure bearing component and the vehicle chassis assembly 3 are connected by the anchoring assembly sealing, so that the flexible pressure bearing component and the vehicle chassis assembly 3 form the closed supercharged space 6.

[0077] In an embodiment of the present application, when the vehicle chassis assembly 3 is a type of chassis, the manned supercharged vehicle has a vehicle chassis assembly 3, a second cab 5 and a carriage 2 which are independently arranged, the first support structure 41 and the second support structure 43 are frame structures similar to the structure shape of the carriage 2, the first support structure 41 and the second support structure 43 are arranged inside the carriage 2, and the overall size of the first support structure 41 is greater than that of the second support structure 43, the first support structure 41 and the second support structure 43 are fixed by connecting pieces at the contact with the vehicle chassis assembly 3, and the flexible pressure bearing component is arranged between the first support structure 41 and the second support structure 43. In order to form a closed supercharged space 6 between the flexible pressure bearing component and the vehicle chassis assembly 3, the flexible pressure bearing component and the vehicle chassis assembly 3 are connected by the anchoring assembly sealing, so that the flexible pressure bearing component and the vehicle chassis assembly 3 form the closed supercharged space 6.

[0078] It can be understood that the carriage 2 in an embodiment is arranged as a three-dimensional rectangular frame structure, in order to as far as possible not to affect the internal area of the original carriage 2, as a preferred embodiment, the structure shape of the first support structure 41 and the second support structure 43 is arranged as a three-dimensional rectangular frame structure. Of course, the internal structure shape of the carriage 2 can also be arranged as a cylindrical body, a prism and other structure shapes, and the structure shape of the first support structure 41 and the second support structure 43 is adjusted correspondingly, so as to maximize the use of the internal space of the original carriage 2.

[0079] In another embodiment of the present application, when the vehicle chassis assembly 3 is a second type chassis, the manned pressurized vehicle has a second cab 5 independent of the pressure-containing sealed structure 4, the first support structure 41 and the second support structure 43 are frame structures similar in shape to the vehicle cabin 2, the first support structure 41 and the second support structure 43 are fixed by connecting pieces at the contact positions with the vehicle chassis assembly 3, and the flexible pressure-containing component is arranged between the first support structure 41 and the second support structure 43. In order to form a closed pressurized space 6 between the flexible pressure-containing component and the vehicle chassis assembly 3, the connecting position between the flexible pressure-containing component and the vehicle chassis assembly 3 is sealed and connected by an anchoring assembly. In this way, the flexible pressure-containing component and the upper surface of the vehicle chassis assembly 3 form a closed pressurized space 6, and the closed pressurized space 6 is used as an activity area for the passengers.

[0080] In another embodiment of the present application, when the vehicle chassis assembly 3 is a third type chassis, the manned pressurized vehicle has a pressure-containing sealed structure 4 mounted on the upper surface of the vehicle chassis assembly 3, and a first cab 1 arranged in the pressure-containing sealed structure 4 and located at the front side of the vehicle chassis assembly 3. The first cab 1 is connected to the flexible pressure-containing component. The structure shape of the first support structure 41 and the second support structure 43 can be adjusted according to the shape of the vehicle body. The flexible pressure-containing component between the first support structure 41 and the second support structure 43 is sealed and connected to the vehicle chassis assembly 3 by an anchoring assembly, so as to form a closed pressurized space 6 between the flexible pressure-containing component and the vehicle chassis assembly 3.

[0081] Preferably, the first support structure 41 and the second support structure 43 are made of aluminum alloy material. Compared with the pressurized cabin body made of traditional steel structure material, the pressure-containing sealed structure made of the first support structure 41, the flexible pressure-containing component and the second support structure 43 in the embodiment has a greatly reduced weight, and realizes a lightweight structure of the pressure-containing sealed structure 4.

[0082] Further, in the specific embodiment of the present application, the flexible pressure-containing component is a flexible air film 42. The air film itself is a flexible structure, and the stress is an uplift force. The air film has a light weight, and can reduce the pressure on the vehicle chassis assembly 3. In addition, the air film has a high compression strength and good ductility, and can offset the inertial force movement of the air film caused by the longitudinal and transverse forces of the vehicle cabin 2, and can withstand a large impact load.

[0083] Compared with the traditional manned pressurized vehicle, the traditional manned pressurized vehicle generally adopts a steel sealed cabin, and the minimum weight of the sealed part is about 800 kg. In the embodiment, the flexible air film 5 is used as the sealing and pressure-containing material, and only a steel skeleton is used as the sealing support material, so that a lightweight design is fully implemented, and the mass is reduced by 40% compared with the traditional design. The whole vehicle mass can be controlled within 4.5T, so as to meet the standards of commercial vehicles and the like.

[0084] In some other embodiments, the flexible air film 42 is also made of other flexible pressure-bearing sealing materials (such as polyester fiber, etc.), and has high strength and elastic recovery ability.

[0085] In some other embodiments, the flexible air film 42 is made of high-strength fiber cloth and high-molecular materials, etc., so that the surface of the fiber cloth can be kept clean for a long time, and the skin-friendliness of the fiber cloth can be improved by setting a skin-friendly layer, so that the fiber cloth is more comfortable to use.

[0086] It should be particularly pointed out that, in order to ensure safety, the flexible pressure-bearing component is also provided with a sealing breaking assembly, which forms a 20cm*5cm strip-shaped pressure relief opening on the flexible air film 42 in an emergency, so that the pressure in the sealed pressurized space 6 can be quickly reduced, and the passengers can quickly leave the sealed pressurized space 6 within 30 seconds in an emergency.

[0087] Further, as shown in Figure 7 , 8 The anchoring assembly includes an anchoring base 11 fixed on the vehicle chassis assembly 3, an air film pressing plate 12, and anchoring bolts 16, the anchoring bolts 16 are threaded through the air film pressing plate 12, the flexible air film 42 and the anchoring base 11, so that the air film pressing plate 12 presses the flexible air film 42 tightly on the anchoring base 11.

[0088] In specific embodiments of the present application, in order to connect the flexible air film 42 to the upper surface of the vehicle chassis assembly 3, the anchoring base 11 is fixedly arranged on the upper surface of the vehicle chassis assembly 3 as a mounting and fixing base, the flexible air film 42 and the anchoring base 11 are sealingly connected through the anchoring bolts 16 and sealing gaskets, and the air film pressing plate 12 is pre-installed between the flexible air film 42, which can reduce the amount of work for vehicle modification.

[0089] Further, as shown in Figure 8 The anchoring assembly further includes a U-shaped pressing plate 13 inserted on the anchoring base 11, and the anchoring bolts 16 penetrate through the two side surfaces of the U-shaped pressing plate 13 and are locked on the anchoring base 11.

[0090] In specific embodiments of the present application, the anchoring base 11 is provided with the U-shaped pressing plate 13, the U-shaped pressing plate 13 is inserted on the anchoring base 11, and the anchoring bolts 16 penetrate through the U-shaped pressing plate 13 and lock it on the anchoring base 11. Through the arrangement of the U-shaped pressing plate 13, the side of the flexible air film 42 close to the anchoring base 11 is completely supported and pressed on the side surface of the U-shaped pressing plate 13, and the side surface of the U-shaped pressing plate 13 completely covers the bolt hole on the anchoring base 11, realizing the sealing of the flexible air film 42. The U-shaped pressing plate 13 is fastened on the anchoring base 11 by the anchoring bolts 16, which is simple to install and can be flexibly and dispersedly arranged.

[0091] Preferably, to improve the sealing effect between the flexible air membrane 42 and the anchoring base 11, the side of the U-shaped pressing plate 13 close to the flexible air membrane 42 can be appropriately lengthened, so that the contact area between the flexible air membrane 42 and the anchoring base 11 can be increased, the stability effect can be improved, and at least two oppositely locked anchoring bolts 16 can be arranged locally and circumferentially, so as to improve the sealing properties of the key nodes.

[0092] Further, as shown in Figure 8 The anchoring assembly further comprises a ball head pressing plate 14 arranged between the air membrane pressing plate 12 and the flexible air membrane 42. The ball head pressing plate 14 is a straight plate body structure, and the upper edge of the straight plate body structure has a pipe body structure. The anchoring bolt 16 penetrates the straight plate body structure and locks the ball head pressing plate 14 between the air membrane pressing plate 12 and the flexible air membrane 42.

[0093] Similarly, the arrangement of the ball head fastener can realize the sealing of the flexible air membrane 42 in a targeted manner. The ball head pressing plate 14 is also provided with a through hole corresponding to the position of the anchoring bolt 16, and there is a certain height difference between the ball head pressing plate 14 and the air membrane pressing plate 12. The anchoring bolt 16 can be forced along its axis direction at all times, that is, the ball head pressing plate 14 can be reliably pressed.

[0094] Further, as shown in Figure 8 The anchoring assembly further comprises a stable connecting plate 15 arranged between the ball head pressing plate 14 and the flexible air membrane 42. The anchoring bolt 16 penetrates the stable connecting plate 15 and locks it between the anchoring base 11 and the air membrane pressing plate 12. The stable connecting plate 15 is connected with the second support structure 5.

[0095] Therefore, the U-shaped pressing plate 13 and the ball head pressing plate 14 can improve the effectiveness of the anchoring assembly in sealingly connecting the flexible air membrane 42 and the vehicle chassis assembly 3, while reducing the wear of the flexible air membrane 42. The stable connecting plate 15 can further ensure the stability and reliability of the connection between the flexible air membrane 42 and the vehicle chassis assembly 3.

[0096] Of course, the inner wall of the vehicle compartment 2 can also be sealingly connected with the flexible air membrane 42 through the anchoring assembly, so as to improve the stability of the flexible air membrane 42 in the vehicle compartment 2.

[0097] Further, as shown in Figure 7 The first support structure 41 is a metal mesh structure, and the second support structure 43 is a metal skeleton structure.

[0098] Specifically, the first support structure 41 is a metal mesh structure, the bottom of the first support structure 41 is fixed on the anchor base 11 of the anchor assembly, and the main function is to limit the deformation space of the flexible air film 42, to fit the aluminum alloy vehicle shell and avoid damage to the vehicle compartment 2 (vehicle shell) caused by deformation of the flexible air film 42; the second support structure 43 is a metal framework structure, when the flexible air film 42 is not pressurized, the flexible air film 42 can be attached to the outer surface of the inner lining metal framework, and the inner lining metal framework is also a fixed support of the interior decoration and the like.

[0099] Finally, the first support structure 41 and the second support structure 43 are further fixed and connected with the vehicle chassis assembly 3 by welding.

[0100] Therefore, the first support structure 41 serves as an external support of the flexible air film 42, which can avoid that the pressure of the pressurized area is loaded to the inner wall of the vehicle compartment 2; the second support structure 43 serves as an internal support of the flexible air film 42 and is also a fixed support of the automotive interior structure, that is, the automotive interior structure is installed on the second support structure 43.

[0101] Further, as shown in Figure 7 , the first support structure 41 and the inner wall of the vehicle compartment 2 are filled with the heat preservation and noise reduction material 10, and the second support structure 43 is provided with a plurality of airbags away from the inner wall of the vehicle compartment 2.

[0102] As a preferred mode of another embodiment of the present application, the heat preservation and noise reduction material 10 can sufficiently improve the comfort of the occupants and provide certain heat preservation performance, which is beneficial to control the energy consumption of the whole vehicle. Exemplarily, the heat preservation and noise reduction material 10 is selected from butyl rubber, and the thickness is 10-30 mm.

[0103] The second support structure 43 is provided with a plurality of airbags, which can ensure the safety of the occupants when a safety accident occurs.

[0104] Further, as shown in Figure 2 , 3 , the manned pressurized vehicle further comprises an electric energy management system, the electric energy management system comprises a generator and an energy storage battery, the generator is connected with the engine of the vehicle chassis assembly, and the energy storage battery and the pressurization system 9 are electrically connected with the generator.

[0105] Specifically, the electric energy management system uses the residual power of the engine to supply power to the devices of the pressurization system 9 and other devices, and in the process of driving the manned pressurized vehicle, the overall power consumption of the normal system is lower than the power of the generator, and the electric energy is also stored in the energy storage battery. When the engine is in a state of shutdown, failure or the like, the generator cannot supply power, and the battery is used as an UPS power supply, which is inverted to supply power to the control, safety and other key systems, to ensure the safety of the personnel and the normal entry and exit.

[0106] ​For example, in this embodiment, the generator is a vehicle-mounted low-noise generator, which is connected to the power take-off via the transfer case drive shaft to provide single-phase 220V AC power.

[0107] In addition, the passenger-carrying pressurized vehicle also includes a depressurization system, which connects the flexible air membrane 42 to the sealed pressurized space 6 formed by the chassis assembly 3. In the event of a fire, collision, or other accident, the on-board controller adaptively activates the depressurization system for automatic depressurization, or passengers can manually depressurize the vehicle to facilitate rescue and evacuation.

[0108] Embodiments of the present invention also provide a pressurization method for a passenger-carrying pressurized vehicle. Based on the passenger-carrying pressurized vehicle described above, the pressurization method includes the following steps:

[0109] During normal use, the driver and passengers of the manned pressurized vehicle enter the interior of the pressure-bearing sealed structure 4 and close the doors and windows. They control the pressurization fan to pressurize the interior of the sealed pressurized space 6 by operating the pressurization system 9, and pressurize to the set pressure value within a limited time.

[0110] During vehicle operation, the supercharging system 9 automatically adjusts the opening time and opening range of the electric valve on the supercharging system 9 based on the data fed back by the pressure, carbon dioxide concentration sensor and temperature and humidity sensor in the sealed supercharging space 6. Through the cooperation of the electric valve and the supercharging fan, the air circulation and renewal are achieved while maintaining the stable pressure inside the sealed supercharging space 6.

[0111] When the vehicle is about to reach its destination, the electric valve is opened by operating the supercharging system 9 to release pressure inside the sealed supercharging space 6 within a limited range. When the internal pressure drops to close to the external ambient pressure, the occupants open the airtight doors and windows on the pressure-bearing sealed structure 4 and leave the passenger-carrying supercharged vehicle.

[0112] Specifically, the passenger-carrying booster vehicle has the following operating procedures:

[0113] During normal use, after the driver and passengers of the passenger-carrying pressurized vehicle enter the vehicle and close the doors and windows, they control the pressurization fan to pressurize the sealed pressurized space 6 by operating the pressurization system 9, and pressurize to the set pressure value within a limited time.

[0114] During vehicle operation, the supercharging system 9 automatically adjusts the opening time and opening range of the electric valve based on data from the in-vehicle pressure and carbon dioxide concentration sensors, temperature and humidity sensors, etc. The cooperation between the electric valve and the supercharging fan maintains the internal pressure of the sealed supercharging space 6 while achieving air circulation and renewal.

[0115] When the vehicle is about to reach its destination, the electric valve is opened by operating the pressurization system 9 to depressurize the sealed pressurized space 6 within a limited range. When the internal pressure drops to near the external environmental pressure, the occupants can open the airtight door 7 and airtight window 8 to leave the pressurized vehicle.

[0116] In case of emergency, the supercharging system 9 can open the electric valve to its maximum extent or open the manual ball valve to depressurize the interior of the sealed supercharging space 6 as quickly as possible. If the electric valve fails, the window breaking tool provided with the vehicle can be used to break the weak area of ​​the airtight window 8 and escape quickly.

[0117] During vehicle operation, the power management system provides power to the supercharging system 9 and the chassis assembly 3, ensuring the stability of equipment operation, and is equipped with an air conditioning system to regulate the temperature and humidity inside the cabin.

[0118] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this invention.
