Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and specifically relates to an oxygen production system and a vehicle. Background Art

[0002] As people pay more attention to the living environment and various reports, interviews and popular science on the environment and health spread rapidly, the society's attention to the environment and health continues to rise. Among them, the attention to air quality, which is closely related to people's health, continues to rise. As a result, the requirements for the air quality and comfort in the car are gradually increasing. Elderly people or young children may also suffer from head hypoxia due to long-distance car rides, sudden braking and stopping of vehicles, and then they will experience dizziness, headaches, tinnitus, nausea, vomiting, palpitations, shortness of breath, shortness of breath, rapid breathing, and rapid and weak heartbeats.

[0003] Most of the existing oxygen concentrators are portable, semiconductor and other structures. The oxygen concentrator is turned on by a 12V power supply to meet the oxygen production needs, but this type of oxygen concentrator is expensive. During the operation of the existing oxygen concentrator, there are two key requirements for the air compressor when compressing air: 1) The air entering the compressor for compression needs to be purified; 2) During the compression process of the compressor, two electronic fans need to be used to dissipate heat into the machine through the heat dissipation holes of the compressor housing. In this way, the fuselage cannot be completely sealed, which also causes the traditional air compressor to fail to meet the IP67 waterproof and dustproof requirements, and thus cannot be placed outside the vehicle (usually placed in the trunk of the vehicle, the noise is easily transmitted to the passenger compartment, which has a great impact on the NVH performance of the vehicle). Moreover, this type of oxygen concentrator is large in size and will take up more space in the vehicle.

[0004] For example, the patent document with publication number CN115708934A discloses an intelligent induction type plateau vehicle-mounted oxygen supply device, including a shell and a display screen, a display screen is fixedly connected to the front outer wall of the shell, a button is fixedly connected to the front outer wall of the shell located at the lower side of the display screen, and a battery pack is arranged on the left side of the shell. The present invention is provided with an air pump, a conduit, a valve, an airbag, a movable plate, a control switch, an oxygen concentrator and a fixed pipe. When in use, the airbag can be filled with gas of suitable air pressure by the air pump. When the car drives to a certain altitude, the airbag will expand under the action of the internal air pressure. The expanded airbag pushes the movable plate to move, so that the control switch contacts and starts the oxygen concentrator, and the through hole is connected with the fixed pipe. At this time, the oxygen generated by the oxygen concentrator is discharged through the fixed pipe, realizing automatic oxygen production and oxygenation operation, which is convenient for timely oxygen production and use, and the use effect is good. The technical solution disclosed in the patent document also cannot solve the technical problems recorded above. Utility Model Content

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower" and similar expressions used in this article are for illustrative purposes only.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0018] like Figure 1 As shown, the utility model provides an oxygen production system, including an air compressor 6, which is arranged in the cabin of a vehicle, an air inlet of the air compressor 6 is connected to the air conditioning box 4 of the vehicle, and an air outlet of the air compressor 6 is connected to an oxygen storage tank.

[0019] Specifically, if Figure 1 As shown, the air inlet of the air compressor 6 is connected to the air outlet of the air conditioning box 4 through the air pipe 5, and the purified air filtered by the PM2.5 filter element of the air conditioning box 4 is led to the air compressor 6 through the air pipe 5. The air compressor 6 is arranged in the cabin position. Through the compression of the air compressor 6, low-temperature and high-pressure air is discharged and introduced into the oxygen storage tank 7 through the air pipe. The oxygen storage tank is integrated with a molecular sieve, which can filter nitrogen molecules, and oxygen molecules enter the oxygen storage tank after passing through the molecular sieve.

[0020] Air is introduced into the molecular sieve and oxygen storage tank 7 through the trachea, and the nitrogen in the air is separated from the oxygen through the molecular sieve to produce oxygen, and then the oxygen is stored in the oxygen storage tank 7, and the oxygen storage tank 7 is connected to the oxygen bar outlet 8, and the oxygen bar outlet 8 is set in the passenger compartment. After opening the oxygen bar outlet 8, oxygen therapy can be performed. Oxygen inhalation can directly increase the arterial blood oxygen content, thereby effectively alleviating the symptoms of hypoxia.

[0021] Since the air compressor 6 rotates at a high speed, the compressor controller and the compressed air need to be cooled, otherwise the controller is easily burned and the high-temperature air enters the molecular sieve, thus affecting the service life of the molecular sieve. Considering the complex cabin environment, the vehicle must be dustproof and waterproof, and air heat dissipation cannot be used. Therefore, coolant is introduced from the vehicle thermal management cooling system to cool the air compressor 6, and the air compressor 6 is connected to the vehicle's thermal management cooling system.

[0022] like Figure 1As shown, the thermal management cooling system includes a low-temperature radiator 1 and a radiator fan 2. The radiator fan 2 dissipates heat from the low-temperature radiator 1. The low-temperature radiator 1 and the radiator fan 2 are arranged relative to each other. The water inlet and outlet of the air compressor 6 are connected to the low-temperature radiator 1 through a cooling pipe. The coolant enters the air compressor 6 from the outlet of the low-temperature radiator 1 through the cooling pipe, takes away the heat generated by the air compressor 6 when it is working through the cooling channel set in the air compressor 6, and then returns to the inlet of the low-temperature radiator 1. The heat of the low-temperature radiator 1 is dissipated to the environment through the radiator fan 2, thereby completing the cooling work of the air compressor 6.

[0023] Preferably, the air compressor 6 is installed in the engine room of the vehicle by bolts, which is convenient for disassembly and assembly. The air compressor 6 is arranged in the engine room, separated from the passenger compartment, and the noise is not easily transmitted to the passenger compartment, and the NVH performance of the whole vehicle can be effectively improved.

[0024] The utility model also provides a vehicle, including the oxygen production system of the above structure. The specific structure of the oxygen production system can be referred to Figure 1 Since the vehicle of the utility model includes the oxygen production system in the above embodiment, it has all the advantages of the above oxygen production system.

[0025] In this embodiment, the vehicle is a new energy electric vehicle.

[0026] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
