Description

Technical Field

[0001] This utility model relates to the field of oxygen generation device technology, specifically to a vehicle-mounted oxygen generator system. Background Technology

[0002] There is a wide market demand for vehicle-mounted oxygen generation and supply equipment, such as the oxygen intake needs of vehicles in high-altitude areas, the oxygen supply needs of passengers or equipment in ordinary vehicles, and the oxygen supply needs of special vehicles such as rescue and medical vehicles.

[0003] Home oxygen concentrators are not suitable for use in cars due to their large size and weight. There are also some portable oxygen concentrators or oxygen generation systems designed specifically for cars. They are relatively small and more suitable for use in cars, but they mostly follow the structure of home oxygen concentrators, integrating the air compressor and oxygen generation components into one unit. They still need to ensure that there is enough space in the vehicle to place them. They have high requirements for vehicle space and need to be placed in a well-ventilated location that avoids direct sunlight to ensure stable operation of the equipment.

[0004] The engine compartment of a vehicle has a large space, but if an oxygen concentrator is placed there, the high temperature inside the engine compartment will not only hinder the long-term operation of the air compressor, but also cause the molecular sieve in the oxygen concentrator to have a reduced oxygen output rate due to the high temperature environment. Utility Model Content

[0005] Therefore, this utility model provides a vehicle-mounted oxygen generator system that separates the air compressor and the oxygen generator assembly. The air compressor is placed in the engine compartment, which has a large space in the vehicle, and is cooled by an air supply and cooling assembly to reduce the adverse effects of high engine compartment temperature on the operation of the air compressor. The oxygen generator assembly can be placed in any part of the vehicle that is conducive to maximizing its oxygen generation efficiency, thereby solving the above-mentioned defects in the prior art.

[0006] An on-board oxygen generator system includes an air compressor and an oxygen generation component connected to the air compressor. The air compressor is configured in the engine compartment of the vehicle. The engine compartment also includes an air supply and cooling component for reducing the temperature of the air compressor during operation and a cooling duct connected to the air supply and cooling component.

[0007] In this embodiment of the present invention, the air supply and heat dissipation assembly includes an air supply mechanism and a heat insulation cover. The air compressor is disposed inside the heat insulation cover. The heat insulation cover is provided with an air outlet 1 and an air outlet 2 that connect the inside and outside of the heat insulation cover. At least a portion of the heat dissipation channel passing through the surface of the air compressor is formed between the air outlet 1 and the air outlet 2 located inside the heat insulation cover. The air supply mechanism is configured to cause the external gas of the heat insulation cover to dissipate the hot air inside the heat insulation cover through the heat dissipation channel.

[0008] In this embodiment of the present invention, the oxygen generating component is disposed outside the heat insulation cover, and the gas compressed by the air compressor is connected to the air inlet of the oxygen generating component through the exhaust pipe.

[0009] In this embodiment of the present invention, the air outlet of the cooling duct is connected to the second air outlet, the air inlet of the cooling duct is disposed on the wall of the engine compartment and communicates with the outside of the engine compartment, and an air supply duct is formed inside the cooling duct that communicates with the heat dissipation channel.

[0010] In this embodiment of the utility model, the air supply mechanism is configured as a cooling fan, and a mounting part is provided inside the heat insulation cover on one side of the air outlet, and the cooling fan is disposed in the mounting part.

[0011] In this embodiment of the present invention, filter cotton is provided on the heat insulation cover on one side of the air vent and the air vent, and the filter cotton is used to prevent external impurities from entering the heat insulation cover.

[0012] In this embodiment of the invention, the air compressor is connected to an air inlet pipe, and the air inlet of the air inlet pipe is located outside the heat insulation cover.

[0013] In this embodiment of the utility model, a sheet metal fixing bracket is also included. The sheet metal fixing bracket is installed on the engine compartment wall. The air compressor is installed on the heat insulation cover through a primary vibration isolation component. The heat insulation cover is installed on the lower surface of the sheet metal fixing bracket through a secondary vibration isolation component.

[0014] In this embodiment of the invention, the heat insulation cover is made of plastic.

[0015] In this embodiment of the invention, the oxygen generating component is located in the trunk and / or driver's cabin of the vehicle.

[0016] This utility model has the following advantages:

[0017] (1) The vehicle-mounted oxygen generator system of this utility model separates the air compressor and the oxygen generator component. The air compressor is located in the engine compartment of the vehicle, which has a large space, while the oxygen generator component can be located in any part of the vehicle that is conducive to its oxygen generation efficiency, such as the trunk and / or the driver's cabin. This can reduce the requirements of the oxygen generator system layout on the vehicle's interior space, improve space utilization and layout efficiency.

[0018] (2) The vehicle-mounted oxygen generator system of this utility model is equipped with an air supply and heat dissipation component for air compressor heat dissipation inside the engine compartment. On the one hand, it can extend the service life of the air compressor; on the other hand, it can also avoid the initial temperature of the compressed gas of the air compressor being too high, which would lead to the gas temperature entering the oxygen generator component after compression being too high, affecting the oxygen generation efficiency of the oxygen generator system, or requiring additional or higher power cooling facilities to cool down the compressed gas, thereby reducing the cost of gas use; in addition, the air supply and heat dissipation component of this utility model can be used in conjunction with the cooling duct section to adopt a passive air supply method, that is, to use the oncoming wind of the vehicle to carry away the heat on the surface of the air compressor, thereby reducing the heat dissipation energy consumption.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] There is a wide market demand for in-vehicle oxygen generators and supply systems. Existing technologies include portable oxygen generators or oxygen systems specifically designed for vehicles. These are relatively small and more suitable for use in cars, but they mostly follow the structure of home oxygen generators, integrating the air compressor and oxygen generation components into one unit. This still requires sufficient space in the vehicle, placing the device in a well-ventilated location away from direct sunlight to ensure stable operation.

[0027] like Figures 1 to 4 As shown, this utility model embodiment provides a vehicle-mounted oxygen generator system, which includes an air compressor 2 and an oxygen generating component 8 connected to the air compressor 2.

[0028] The air compressor 2 described in this embodiment can be configured separately for the oxygen generating assembly 8, or it can be an air supply device for an existing vehicle-mounted air-consuming unit, such as the air compressor used to supply air to the air springs in an air suspension system (not shown in the figure). This allows other vehicle-mounted air-consuming units and the oxygen generating assembly 8 to share a single air intake source, meeting the requirements for vehicle lightweighting.

[0029] Unlike existing technologies, in this embodiment of the invention, the air compressor 2 is located within the vehicle's engine compartment 20. Because the engine compartment 20 has ample space, it meets the space requirements for arranging the oxygen generator system.

[0030] The temperature inside the engine compartment 20 of the vehicle is high, and the air compressor 2 itself also experiences a temperature rise during operation. Placing the air compressor 2 directly inside the engine compartment 20 would be detrimental to its long service life. Therefore, in this embodiment of the invention, an air supply and cooling assembly 100 for reducing the temperature of the air compressor 2 during operation is also provided inside the engine compartment 20.

[0031] For example, the air supply and heat dissipation assembly 100 includes an air supply mechanism 5 and a heat insulation cover 1, and the air compressor 2 is disposed inside the heat insulation cover 1.

[0032] The heat shield 1 of this embodiment can be made of plastic, or other materials with good heat insulation can be selected according to specific circumstances. The function of the heat shield 1 is to reduce heat exchange between the air inside and outside the heat shield 1. In particular, it reduces the impact of the heat from the air inside the engine compartment 20 on the interior of the heat shield 1, and improves the heat dissipation effect of the air supply cooling assembly 100 on the air compressor 2.

[0033] The heat insulation cover 1 is provided with an air vent 3 and an air vent 4 that connect the inside and outside of the heat insulation cover 1 to promote the flow of gas. The air vent 3 and the air vent 4 located inside the heat insulation cover 1 form at least a partial heat dissipation channel that passes through the surface of the air compressor 2.

[0034] In this embodiment of the present invention, the air supply mechanism 5 is configured to cause the external gas of the heat insulation cover 1 to dissipate the hot air generated inside the heat insulation cover 1 due to the operation of the air compressor 2 through the heat dissipation channel.

[0035] The air supply mechanism 5 can be configured as a cooling fan, and a mounting part 7 is provided inside the heat insulation cover 1 on one side of the air outlet 4, and the cooling fan is installed in the mounting part 7. The cooling fan can be replaced with other devices that can supply air.

[0036] In other embodiments, the air supply mechanism 5 may also be located in other parts of the heat insulation cover 1, such as inside the heat insulation cover 1, or on an air passage outside the heat insulation cover 1 that is connected to the heat dissipation channel.

[0037] In this embodiment of the present invention, a cooling duct 11 connected to the air supply and heat dissipation assembly 100 is also provided in the engine compartment 20, and the cooling duct 11 is used to introduce heat dissipation airflow.

[0038] For example: the air outlet of the cooling duct 11 is connected to the air inlet 4, and the air inlet of the cooling duct 11 is located on the wall of the engine compartment 20 and communicates with the outside of the engine compartment 20.

[0039] In some embodiments, the air supply mechanism 5, such as a cooling fan, may be disposed within the cooling duct 11.

[0040] Preferably, the air inlet of the cooling duct 11 is located on the front bulkhead of the engine compartment 20. In this way, when the vehicle is in motion, the oncoming air can automatically enter the interior of the cooling duct 11 and dissipate heat from the air compressor 2, thus at least partially adopting a passive air supply cooling method to save energy.

[0041] The cooling duct 11 forms an air supply duct that communicates with the heat dissipation channel. For example, the cooling duct 11 can be a corrugated pipe, thereby adapting to the needs of different spatial layouts.

[0042] For example, in this embodiment of the present invention, the external gas used for heat dissipation of the air compressor 2 inside the heat insulation cover 1 can be the atmosphere outside the engine compartment 20 of the vehicle, which has a lower temperature than the air compressor 2 during operation.

[0043] When the vehicle is in motion and / or the cooling fan is running, the outside atmosphere of the engine compartment 20 passes through the air supply duct and the cooling flow channel in sequence, carrying away the heat near the air compressor 2 inside the heat shield 1, thereby reducing the temperature of the air compressed by the air compressor 2, which helps to ensure the oxygen output rate of the oxygen generator system (the oxygen output rate of the oxygen generator component usually decreases as the intake air temperature increases).

[0044] In some other embodiments (not shown in the figures), the external gas used for heat dissipation of the air compressor 2 inside the heat shield 1 may also be: gas cooled by the vehicle-mounted refrigeration system (not shown in the figures); exhaust gas discharged from the vehicle-mounted pneumatic equipment at a temperature lower than the gas temperature inside the heat shield 1; or any other gas that promotes heat dissipation of the air compressor 2 inside the heat shield 1.

[0045] The gas discharged from the air vent 3 can be directly discharged into the engine compartment 20 and can be cooled by common air cooling and water cooling methods. Since the cooling method of the engine compartment 20 is existing technology, it will not be described in detail here.

[0046] In other embodiments, the gas discharged from vent 3 can also be discharged to the outside of engine compartment 20 through a pipe.

[0047] In this embodiment of the present invention, in order to prevent external impurities from entering the heat insulation cover 1, filter cotton 9 for filtering impurities is provided on the heat insulation cover 1 on one side of the air vent 3 and the air vent 4.

[0048] In this embodiment of the invention, the air compressor 2 is connected to the intake pipe 6, and the air inlet of the intake pipe 6 is located outside the heat insulation cover 1. Preferably, the air inlet of the intake pipe 6 is also located outside the engine compartment 20 of the vehicle. This prevents the temperature entering the air compressor 2 from becoming too high, which on the one hand extends the service life of the air compressor 2; on the other hand, it avoids the initial temperature of the compressed gas from the air compressor 2 being too high, which would result in the temperature of the gas ultimately compressed and introduced into the oxygen generating assembly 8 being too high, affecting the oxygen generating efficiency of the oxygen generating system, or requiring additional or higher-power cooling facilities to cool the compressed gas, thus reducing gas usage costs.

[0049] For example, a filter 15 is also provided on the air intake pipe 6. The filter 15 is used to filter the intake air impurities of the air compressor 2. The filter 15 is preferably located outside the heat insulation cover 1.

[0050] To ensure connection reliability and vibration isolation effect, the vehicle-mounted oxygen generator system also includes a sheet metal mounting bracket 12, which is installed on the engine compartment 20 wall. The air compressor 2 is mounted on the heat shield 1 via a primary vibration isolation component 13, and the heat shield 1 is mounted on the lower surface of the sheet metal mounting bracket 12 via a secondary vibration isolation component 14.

[0051] In this embodiment of the invention, the oxygen generating component 8 is disposed outside the heat insulation cover 1, and the gas compressed by the air compressor 2 is connected to the air intake end of the oxygen generating component 8 through the exhaust pipe 10. This method of separating the air compressor 2 and the oxygen generating component 8 can more effectively utilize the limited space of the vehicle to complete the spatial arrangement of the oxygen generator system, thereby improving the layout efficiency of the vehicle-mounted oxygen generator system.

[0052] In this embodiment of the invention, the air compressor 2 is installed in the engine compartment 20, which has a relatively large space in the vehicle, and is cooled by the air supply and cooling assembly 100 to improve the service life of the air compressor 2 and reduce the intake temperature of the oxygen generator 8 to ensure the oxygen production rate. The oxygen generator 8 can be installed in any part of the vehicle that is conducive to maximizing its oxygen production efficiency. For example, the oxygen generator 8 is installed in the trunk and / or driver's compartment of the vehicle. Compared to installing the oxygen generator 8 in the engine compartment 20, installing it in these locations is more beneficial in reducing the impact of temperature on the operation of the oxygen generator, thereby ensuring the stable operation of the oxygen production system and the oxygen output rate.

[0053] In summary, the present invention provides a vehicle-mounted oxygen generator system that separates the air compressor and the oxygen generator assembly. This allows the air compressor to be located in the engine compartment, which has a relatively large space in the vehicle, while the oxygen generator assembly can be located in any part of the vehicle that is conducive to maximizing its oxygen generation efficiency, such as the trunk and / or the driver's cabin. This reduces the space requirements of the oxygen generator system layout on the vehicle's interior, improves space utilization and layout efficiency.

[0054] Furthermore, the vehicle-mounted oxygen generator system of this utility model has an air supply and heat dissipation component for cooling the air compressor inside the engine compartment. On the one hand, this can extend the service life of the air compressor 2; on the other hand, it also avoids the initial temperature of the compressed gas from the air compressor 2 being too high, which would result in the temperature of the gas entering the oxygen generator component 8 after compression being too high, affecting the oxygen generation efficiency of the oxygen generator system, or requiring additional or higher-power cooling facilities to cool the compressed gas, thus reducing gas usage costs. In addition, the air supply and heat dissipation component of this utility model can be used in conjunction with the passive air supply method of the cooling duct section, that is, using the oncoming wind of the vehicle to carry away the surface heat of the air compressor 2, which can reduce heat dissipation energy consumption.

[0055] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
