Description

Technical Field

The oxygen concentration in the cabin must adequately meet their health needs. Currently, the demand for in-vehicle oxygen concentrators is gradually increasing, and the market demand is further expanding.

[0003] Most existing vehicles are not equipped with onboard oxygen concentrators, and some models are equipped with aftermarket home-use onboard oxygen concentrators, but their performance does not meet automotive-grade requirements. Currently, there are two main types of installation structures for pre-installed onboard oxygen concentrators: one is located in the front cabin storage box, which is suitable for pure electric vehicles but not for gasoline vehicles or range-extended vehicles, and the harsh working conditions outside the cabin result in a shorter lifespan for the onboard oxygen concentrator; the other is located in the trunk, sacrificing rear cabin storage space, and the oxygen diffusion pipeline is longer, resulting in a lower oxygen uptake rate in the cabin. Both of these oxygen concentrator solutions suffer from poor maintenance of the oxygen concentrator assembly, unsanitary oxygen delivery pipelines, and poor versatility.

It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0033] like Figures 1-9As shown, the vehicle-mounted oxygen generator arrangement structure provided in this embodiment includes: a vehicle body sheet metal 5, a sub-dashboard 3 is provided on the vehicle body sheet metal 5, a vehicle-mounted oxygen generator 4 is provided inside the sub-dashboard 3, an air conditioning unit 1 is provided at the front end of the vehicle body sheet metal 5, the air conditioning unit 1 is connected to the vehicle-mounted oxygen generator 4 through an air duct assembly 2, and an oxygen exhaust port is provided on the vehicle-mounted oxygen generator 4.

[0034] The air conditioning unit 1 is a standard configuration used to provide compressed air to the onboard oxygen generator 4. For example... Figure 3 As shown, the air conditioning unit 1 includes an air conditioning unit body 11. An air conditioning compressor inlet 12 for connection to the air conditioning compressor is provided on the top side of the air conditioning unit body 11, and an oxygen concentrator inlet pipe 13 for connection to the vehicle-mounted oxygen concentrator 4 is provided on the bottom side of the air conditioning unit body 11. Figure 4 As shown, the air conditioning unit 11 contains an air conditioning filter 14, and the inner surface of the air conditioning filter 14 is provided with a MOF sterilization filter 15. The air conditioning unit 1 is mainly used to provide clean air for the vehicle oxygen generator 4 system. As the primary filter of the vehicle oxygen generator system, by adding the MOF sterilization filter 15 to the conventional air conditioning filter, human health can be fully guaranteed. In specific implementation, MOF particles can be spread on the lining of the air conditioning filter 14 to obtain the MOF sterilization filter. MOF material is a porous crystalline material, a porous coordination polymer composed of metal ions and organic ligands. It can activate the oxygen and moisture adsorbed in the pores through electron transport, generating a large number of active oxygen species. It can react without light. Introducing light can increase the amount of oxygen species and holes, further purifying pollutants. It can remove benzene, aldehydes, and other harmful substances, and sterilize and nourish the body, fully ensuring the cleanliness and health of the air intake of the vehicle oxygen generator.

[0035] Furthermore, such as Figure 5As shown, the air duct assembly 2 includes a defrost air duct 21, a left-side face air duct 22, a right-side face air duct 23, an oxygen concentrator intake air duct 24, a rear air duct 25, and a foot air duct 26. The defrost air duct 21 is located on the top of the air conditioning unit 1. The left-side face air duct 22 and the right-side face air duct 23 are respectively located on the left and right sides of the defrost air duct 21. The oxygen concentrator intake air duct 24 is located at the bottom of the air conditioning unit 1 and is connected to the vehicle oxygen concentrator 4. The rear air duct 25 extends from the bottom of the air conditioning unit 1 along the top of the sub-dashboard 3 to the end of the sub-dashboard 3. The foot air duct 26 extends from the bottom of the air conditioning unit 1 along the left and right sides of the sub-dashboard 3 to the rear end face of the sub-dashboard 3, which is approximately flush with the rear end face of the sub-dashboard 3. Specifically, the defrosting duct 21, the left-side face-blowing duct 22, the right-side face-blowing duct 23, the oxygen concentrator air intake duct 24, the rear air-blowing duct 25, and the foot-blowing duct 26 are all made of 100% food-grade self-cleaning PE, meeting automotive-grade requirements for volatile organic compound (VOC) concentration, odor, and health, thus preventing excessive VOC levels from causing harmful gases to flow to subsequent stages. Furthermore, the oxygen concentrator air intake duct 24 has a pipe specification of at least Φ65 to ensure sufficient oxygen flow for subsequent processes. In this invention, the duct assembly 2 integrates air conditioning ducts such as the face-blowing ducts (left-side and right-side face-blowing ducts 22 and 23), the defrosting duct 21, and the foot-blowing duct 26, as well as the independently arranged vehicle-mounted oxygen concentrator air intake duct 24.

[0036] Furthermore, such as Figure 6 As shown, the front end of the sub-dashboard 3 is equipped with an oxygen concentrator air inlet pipe 31. The oxygen concentrator air inlet pipe 13, the oxygen concentrator air inlet duct 24, and the oxygen concentrator air inlet pipe 31 are connected in sequence. The sub-dashboard 3 has an air inlet pipe installation space and reserves some installation points for the vehicle-mounted oxygen concentrator 4. The vehicle-mounted oxygen concentrator 4 is mounted on the sub-dashboard 3 via a vehicle-mounted oxygen concentrator assembly mounting bracket. The vehicle-mounted oxygen concentrator assembly mounting bracket is made of powder metallurgy or cast steel, and the main mounting point specification is not less than M8 to ensure that the entire oxygen concentrator, including the sub-dashboard assembly, meets automotive-grade vibration fatigue and modal decoupling requirements, achieving a first-order mode ≥35Hz. In this invention, the sub-dashboard 3 reserves space and installation points for the vehicle-mounted oxygen concentrator 4, and also serves as a decorative element for the oxygen concentrator's appearance. In addition, after removing the outer decorative panel of the sub-dashboard 3, the vehicle-mounted oxygen concentrator 4 can be directly replaced, making maintenance convenient.

[0037] Furthermore, the sub-dashboard 3 also includes a vehicle-mounted refrigerator and storage compartments. The installation space of the vehicle-mounted oxygen generator 4 is designed to be universally compatible with the three configurations of the vehicle-mounted refrigerator and storage compartments, meeting diverse user needs. The shape and size of the sub-dashboard 3 match the vehicle-mounted oxygen generator 4. The outer contour of the vehicle-mounted oxygen generator 4 is equipped with a ventilator, which is made of PET+PE+EVA to meet automotive-grade NVH noise limits. The vehicle-mounted oxygen generator 4 of this application adopts an integrated design structure, integrating a compressor, molecular sieve, radiator, control module, ventilator, and oxygen and nitrogen exhaust ports (shared vents), separating oxygen and nitrogen from the air to provide oxygen to the cabin.

[0038] Furthermore, such as Figure 7 As shown, the vehicle body sheet metal 5 includes a front floor 51. The vehicle body sheet metal 5 has pre-reserved fixing points for mounting the onboard oxygen generator 4. A main mounting point sheet metal bracket 52 is provided on the oxygen generator assembly fixing point. The onboard oxygen generator 4 is mounted on the main mounting point sheet metal bracket 52 using standard parts. The standard parts are 4×Φ8 in size to fully meet the installation strength requirements. An exhaust port 53 is provided on the front floor 51. The exhaust port 53 serves both as a nitrogen discharge port and a heat dissipation port. The exhaust port 53 matches the nitrogen discharge port of the onboard oxygen generator 4. The exhaust port 53 has a size of Φ60. A Φ60 one-way gas check valve is integrated into the exhaust port 53. The valve body of the one-way gas check valve is coated with sealant at the connection point with the sheet metal stop of the vehicle body sheet metal 5 to ensure the overall vehicle sealing requirements and prevent negative pressure backflow of gas. In this invention, the vehicle body sheet metal 5 is mainly used to fix the vehicle-mounted oxygen generator 4 to ensure reliable installation.

[0039] Furthermore, in one embodiment of the present invention, for vehicles with larger cabin spaces, such as those classified as Class C and above, a diffused oxygen supply system is adopted to ensure the oxygen uptake rate in the cabin. Left and right oxygen output pipelines and diffuser outlets are configured to fully meet the oxygen supply needs of the entire cabin. Specifically, the oxygen outlet of the on-board oxygen generator 4 is connected to a main oxygen delivery pipe, such as... Figure 1 , Figure 2 and Figure 8As shown, the vehicle-mounted oxygen generator 4 has a left-side oxygen delivery pipeline 6 and a right-side oxygen delivery pipeline 7 on its left and right sides, respectively. The main oxygen delivery pipeline is connected to the left-side oxygen delivery pipeline 6 and the right-side oxygen delivery pipeline 7 via multi-port quick-connect fittings to achieve left and right branches of the oxygen output pipeline. The left-side oxygen delivery pipeline 6 reaches the B-pillar and C-pillar via the left carpet; the right-side oxygen delivery pipeline 7 reaches the B-pillar and C-pillar via the right carpet. The specifications of the left-side oxygen delivery pipeline 6 and the right-side oxygen delivery pipeline 7 are not less than Φ8, and the material of the left-side oxygen delivery pipeline 6 and the right-side oxygen delivery pipeline 7 is food-grade self-cleaning silicone. The left-side oxygen delivery pipeline 6 is provided with multiple left-side oxygen diffusion ports 8, and the right-side oxygen delivery pipeline 7 is provided with multiple right-side oxygen diffusion ports 9. Through the oxygen delivery pipelines (left-side oxygen delivery pipeline 6 and right-side oxygen delivery pipeline 7) and oxygen diffusion ports (left-side oxygen diffusion ports 8 and right-side oxygen diffusion ports 9) on both sides, oxygen can be diffused throughout the entire cabin.

[0040] Furthermore, each of the left-side oxygen diffuser ports 8 is respectively installed on the trim panels of the left-side B-pillar and C-pillar, and each of the right-side oxygen diffuser ports 9 is respectively installed on the trim panels of the right-side B-pillar and C-pillar. The number of left-side oxygen diffuser ports 8 and right-side oxygen diffuser ports 9 is no less than four. Each left-side oxygen diffuser port 8 and each right-side oxygen diffuser port 9 is an injection-molded part with a pre-reserved pipe installation port. Insect screens and flame arresters are installed on each left-side oxygen diffuser port 8 and each right-side oxygen diffuser port 9 to ensure safe and unobstructed gas flow. The outer shell of each left-side oxygen diffuser port 8 and each right-side oxygen diffuser port 9 is made of PC+ABS. Compared with top-mounted oxygen supply pipelines, this pipeline arrangement effectively avoids the deployment path of the left and right side air curtains on the ceiling, ensuring the safe deployment of the air curtains, and the overall path is shorter.

[0041] Furthermore, in another embodiment of the invention, a centralized oxygen supply system is used for vehicles with smaller cabin spaces, such as those classified as B-class or lower. Specifically, as... Figure 9 As shown, an oxygen central diffusion port 10 is provided on the rear side of the sub-dashboard 3. After oxygen is discharged from the oxygen outlet of the on-board oxygen generator 4, it diffuses into the entire cabin through the oxygen central diffusion port 10. Furthermore, a flame arrestor valve is arranged at the oxygen central diffusion port 10 to prevent flames from entering the oxygen outlet pipeline and ensure gas circuit safety. This solution is economical and practical for vehicles with smaller cabins.

[0042] This invention provides two forms of oxygen supply: diffused oxygen supply for vehicles with larger cabin spaces, such as those in Class C and above, and centralized oxygen supply for vehicles with smaller cabin spaces, such as those in Class B and below. In specific implementation, the system can be selected according to the vehicle model. The only difference between different vehicle models is the pipe configuration size. The installation points are universal, making it highly valuable for promotion.

[0043] The vehicle-mounted oxygen generator layout structure provided in this embodiment of the invention is arranged in the cabin, accommodating pure electric, range-extended, and fuel-powered vehicles. It features a short oxygen diffusion pipeline path, rapid oxygen uptake rate, clean and hygienic oxygen delivery pipeline, and does not occupy rear compartment storage space. Furthermore, this vehicle-mounted oxygen generator layout structure is compatible with both Class B and Class C and above vehicles, and the installation points are universal. The overall structural solution has good versatility, is economical and practical, healthy and environmentally friendly, and easy to maintain.
