Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to an on-board oxygen generation and temperature regulation system. Background Technology

[0002] Passengers are prone to problems such as hypoxia and fatigue when driving in cold high-altitude areas, especially in areas above 3,000 meters above sea level, where the atmospheric oxygen content is significantly reduced. In order to ensure driving safety and comfort, the vehicle needs to continuously supply oxygen and heat. Therefore, it is necessary to integrate air conditioning and oxygen generation systems into the car.

[0003] The existing air conditioning and oxygen generation systems operate independently, requiring two separate sets of equipment, which occupy a large amount of space and encroach on the interior space of the vehicle. Utility Model Content

[0004] The main purpose of this utility model is to propose an on-board oxygen generation and temperature control system, which aims to solve the problem of excessive space occupation of existing on-board oxygen generation and temperature control equipment.

[0005] To achieve the above objectives, this utility model proposes an in-vehicle oxygen generation and temperature control system, including an oxygen generation mechanism and an air conditioning mechanism. The oxygen generation mechanism includes a compression assembly, an oxygen generation component, and an oxygen supply pipe that can communicate with the vehicle cabin. The air conditioning mechanism includes a drive motor. The compression assembly includes a cylinder and a piston. The piston is movably disposed in the cylinder. The piston is connected to the output shaft of the drive motor through a transmission structure and is driven by the drive motor to reciprocate within the cylinder. The cylinder is provided with an air inlet and an air outlet. The air outlet is connected to the oxygen supply pipe through the oxygen generation assembly.

[0006] According to some embodiments of the present invention, it also includes an oxygen concentration sensor for detecting the oxygen concentration inside the vehicle, wherein the air inlet of the cylinder is connected to a solenoid valve, and the solenoid valve and the oxygen concentration sensor are electrically connected through a controller.

One end of the eccentric member is connected to the output shaft of the drive motor, and the other end is rotatably connected to the connecting rod. The end of the connecting rod away from the eccentric member is rotatably connected to the piston.

[0008] According to some embodiments of the present invention, the air conditioning mechanism further includes an air outlet duct and an air outlet, wherein the oxygen supply duct and the air outlet duct are both connected to the air outlet.

[0009] According to some embodiments of this utility model, a mixing mechanism is also included. The mixing mechanism has a mixing chamber that can accommodate and mix oxygen-supplying cold air and air-conditioning hot air. A pressure gauge is provided in the mixing chamber for detecting the air pressure in the mixing chamber. The oxygen supply pipe and the air outlet pipe are both connected to the air outlet through the mixing chamber. A first flow valve and a first thermometer are provided on the oxygen supply pipe. A second flow valve and a second thermometer are provided on the air outlet pipe. A third thermometer is provided on the air outlet. The first flow valve, the second flow valve, the first thermometer, the second thermometer, the third thermometer, and the pressure gauge are electrically connected through a controller.

[0010] According to some embodiments of the present invention, it further includes a switching mechanism and a nasal oxygen supply module. The switching mechanism is disposed in the mixing chamber, and the oxygen supply pipe is connected to the nasal oxygen supply module through the switching mechanism.

[0011] According to some embodiments of this utility model, the switching mechanism includes an oxygen outlet pipe and multiple blades. The oxygen outlet pipe is equipped with an electrically controlled valve. The oxygen outlet pipe and the oxygen supply pipe are connected by the multiple blades. The multiple blades are arranged radially, and the roots of the multiple blades are spaced apart in the circumferential direction of the oxygen supply pipe to form a gas channel communicating with the oxygen supply pipe and the oxygen outlet pipe, so that the oxygen inhalation nozzle of the nasal oxygen supply module passes through the oxygen outlet pipe and the gas channel in sequence and is detachably connected to the oxygen supply pipe.

[0012] According to some embodiments of the present invention, the oxygen generating component includes a rotary valve and two molecular sieve adsorption cylinders. Both molecular sieve adsorption cylinders are connected to the oxygen supply pipeline through the rotary valve. By driving the sliding plate inside the rotary valve to rotate, compressed air can be alternately introduced into the two molecular sieve adsorption cylinders.

[0013] According to some embodiments of the present invention, the molecular sieve adsorption cylinder is filled with activated carbon; and / or, the air outlet of the cylinder and the inlet of the rotary valve are connected by a filter.

[0015] This utility model has at least the following beneficial effects:

[0016] In this invention, the piston of the compression assembly is connected to the output shaft of the drive motor via a transmission structure, causing the piston to reciprocate within the cylinder driven by the drive motor. This compresses external air entering through the intake port within the cylinder and outputs it to the oxygen generation assembly through the outlet. As the compressed air flows through the oxygen generation assembly, nitrogen is adsorbed, and the remaining gas is enriched into a high concentration of oxygen, which is then output to the vehicle cabin via the oxygen supply pipe to provide oxygen. In this invention, the oxygen generation mechanism and the air conditioning mechanism share the drive motor, eliminating the need for a separate drive component for the oxygen generation mechanism, reducing space requirements, and improving system integration.

[0026] This utility model provides an on-board oxygen generation and temperature control system. Figures 1 to 3 This invention provides a specific embodiment of an on-board oxygen generation and temperature control system.

[0027] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a vehicle-mounted oxygen generation and temperature control system 100, including an oxygen generation mechanism 1 and an air conditioning mechanism 2. The oxygen generation mechanism 1 includes a compression assembly 11, an oxygen generation assembly 12, and an oxygen supply pipe 13 that can communicate with the vehicle cabin. The air conditioning mechanism 2 includes a drive motor 23. The compression assembly 11 includes a cylinder 111 and a piston. The piston is movably disposed in the cylinder 111. The piston is connected to the output shaft of the drive motor 23 through a transmission structure 112 and is driven by the drive motor 23 to reciprocate within the cylinder 111. The cylinder 111 is provided with an air inlet and an air outlet. The air outlet is connected to the oxygen supply pipe 13 through the oxygen generation assembly 12.

[0028] In this invention, the piston of the compression assembly 11 is connected to the output shaft of the drive motor 23 via a transmission structure 112, causing the piston to reciprocate within the cylinder 111 driven by the drive motor 23. This allows external air entering from the intake port to be compressed within the cylinder 111 and output from the outlet to the oxygen generating assembly 12. As the compressed air flows through the oxygen generating assembly 12, nitrogen is adsorbed, and the remaining gas is enriched into a high concentration of oxygen, which is then output to the vehicle cabin via the oxygen supply pipe 13 to provide oxygen. In this invention, the oxygen generating mechanism 1 and the air conditioning mechanism 2 share the drive motor 23, eliminating the need for a separate drive component for the oxygen generating mechanism 1, reducing space requirements, and improving system integration.

[0029] It should be noted that the drive motor 23 is actually a compressor, and the air conditioning mechanism 2 also includes a condenser 27, an expansion valve 28, an evaporator 29 and a blower. All of the above components are components in existing vehicle air conditioning systems, and their specific positions and connections will not be described in detail.

[0030] In some embodiments, such as Figure 1 and Figure 2 As shown, there are two compression components 11. The air inlets of the two compression components 11 are connected by an air inlet pipe 15, and the air outlets of the two compression components 11 are connected by an air outlet pipe 16. The air outlet pipe 16 is connected to the oxygen generating component 12. This configuration increases the air compression efficiency by increasing the number of compression components 11.

[0031] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, the vehicle-mounted oxygen generation and temperature control system 100 also includes an oxygen concentration sensor 3 for detecting the oxygen concentration inside the vehicle. The air inlet of the cylinder 111 is connected to a solenoid valve 14, and the solenoid valve 14 is electrically connected to the oxygen concentration sensor 3 via a controller. With this configuration, the oxygen concentration sensor 3 detects the oxygen concentration inside the vehicle, and the solenoid valve 14 is connected to the air inlet. When the oxygen concentration inside the vehicle is low, the solenoid valve 14 opens, allowing outside air to enter, and the oxygen generation mechanism 1 begins supplying oxygen. When the oxygen concentration inside the vehicle is high, the solenoid valve 14 closes, and the oxygen generation mechanism 1 stops supplying oxygen, preventing the oxygen concentration inside the vehicle from becoming too high and causing a hazard.

[0032] Specifically, in some embodiments, the opening of the solenoid valve 14 can be adjusted by PID control according to the real-time changes in the oxygen concentration inside the vehicle, so that the oxygen concentration inside the vehicle is always maintained at around 21%.

[0033] The specific structure of the transmission structure 112 is not limited, as long as it ensures that the transmission structure 112 can convert the rotation of the output shaft of the drive motor 23 into the translation of the piston. For example, in some embodiments, such as... Figure 2 As shown, the transmission structure 112 includes an eccentric member 1121 and a connecting rod 1122. One end of the eccentric member 1121 is connected to the output shaft of the drive motor 23, and the other end is rotatably connected to the connecting rod 1122. The end of the connecting rod 1122 away from the eccentric member 1121 is rotatably connected to the piston.

[0034] In some embodiments, such as Figure 1 As shown, the air conditioning unit 2 also includes an air outlet duct 21 and an air outlet 22, and both the oxygen supply duct 13 and the air outlet duct 21 are connected to the air outlet 22. This arrangement, by having the oxygen generating unit 1 and the air conditioning unit 2 share the same air outlet 22, further reduces the space occupied and improves system integration.

[0035] When a vehicle travels in a high-altitude, cold region, it needs to supply both heat and oxygen to the vehicle interior simultaneously. However, since the oxygen in the oxygen generator 1 comes from outside air, and the outside air temperature in high-altitude, cold regions is low, the oxygen output from the oxygen supply pipe 13 is also low. At this time, the air outlet 22 simultaneously outputs both hot air from the air conditioner and cold air from the oxygen supply pipe, resulting in a difference between the temperature of the gas output from the air outlet 22 and the user's desired temperature. Furthermore, the wind speed from the air outlet 22 also differs from the user's desired wind speed. Therefore, to improve user comfort, in some embodiments, such as... Figure 1As shown, the vehicle-mounted oxygen generation and temperature control system 100 also includes a mixing mechanism 4. The mixing mechanism 4 has a mixing chamber 41 that can accommodate and mix oxygen supply cold air and air conditioning hot air. The mixing chamber 41 is equipped with a pressure gauge 42 for detecting the air pressure inside the mixing chamber 41. The oxygen supply pipe 13 and the air outlet pipe 21 are both connected to the air outlet 22 through the mixing chamber 41. The oxygen supply pipe 13 is equipped with a first flow valve 17 and a first thermometer 18. The air outlet pipe 21 is equipped with a second flow valve 24 and a second thermometer 25. The air outlet 22 is equipped with a third thermometer 26. The first flow valve 17, the second flow valve 24, the first thermometer 18, the second thermometer 25, the third thermometer 26 and the pressure gauge 42 are electrically connected through a controller. In this configuration, the oxygen-supplying cold air input from the oxygen supply pipe 13 and the air-conditioned hot air input from the air outlet pipe 21 are first mixed in the mixing chamber 41 and then output from the air outlet 22. The temperature detected by the first thermometer 18, the second thermometer 25, and the third thermometer 26, and the air pressure detected by the pressure gauge 42 are sent to the controller. The controller then controls and adjusts the opening of the first flow valve 17 and the second flow valve 24 to regulate the flow rate of the oxygen-supplying cold air and the air-conditioned hot air output to the mixing chamber 41, thereby regulating the temperature and airflow of the gas output from the air outlet 22. It should be noted that, in practice, the opening of each flow valve is not linearly related to the output flow rate.

[0036] Specifically, the temperature of the gas output from the air outlet 22 can be adjusted by adjusting the opening ratio between the first flow valve 17 and the second flow valve 24, and the wind speed of the gas output from the air outlet 22 can be adjusted by adjusting the specific opening values ​​of the first flow valve 17 and the second flow valve 24.

[0037] If the occupants urgently need oxygen, relying solely on the oxygen supplied from the oxygen supply pipe 13 to diffuse throughout the cabin is insufficient to meet the demand for high-concentration oxygen supply in a short period. Therefore, in some embodiments, such as Figure 1 and Figure 3 As shown, the vehicle-mounted oxygen generation and temperature control system 100 also includes a switching mechanism 5 and a nasal oxygen supply module 6. The switching mechanism 5 is located within the mixing chamber 41, and the oxygen supply pipe 13 is connected to the nasal oxygen supply module 6 via the switching mechanism 5. This configuration allows the oxygen output mode to be switched from diffusion mode to nasal oxygen supply mode via the switching mechanism 5, enabling oxygen to be directly output from the nasal oxygen supply module 6 to meet short-term high-concentration oxygen supply needs.

[0038] Furthermore, in some embodiments, such as Figure 1 and Figure 3As shown, the switching mechanism 5 includes an oxygen outlet pipe 52 and multiple blades 51. The oxygen outlet pipe 52 is equipped with an electrically controlled valve. The oxygen outlet pipe 52 and the oxygen supply pipe 13 are connected by the multiple blades 51. The multiple blades 51 are arranged radially, and the roots of the multiple blades 51 are spaced apart in the circumferential direction of the oxygen supply pipe 13 to form a gas channel communicating with the oxygen supply pipe 13 and the oxygen outlet pipe 52, so that the oxygen inhalation nozzle 61 of the nasal oxygen supply module 6 passes through the oxygen outlet pipe 52 and the gas channel in sequence and is detachably connected to the oxygen supply pipe 13. With this configuration, when the oxygen output mode is diffusion mode, the electronically controlled valve is closed, and oxygen flows through the oxygen supply pipe 13 and is dispersed from the gaps between the blades 51. When the oxygen output mode is nasal oxygen supply mode, the electronically controlled valve is opened, and the occupants manually insert the oxygen inhalation nozzle 61 of the nasal oxygen supply module 6 and connect it to the oxygen supply pipe 13, so that oxygen is directly output from the nasal oxygen supply module 6 to meet the short-term high-concentration oxygen supply needs.

[0039] It should be noted that, since the diffusion mode requires a larger oxygen flow rate, while the nasal oxygen supply mode requires a smaller oxygen flow rate, in some embodiments, the eccentric member 1121 is connected to the output shaft of the drive motor 23 via a reducer with a disconnect mechanism. With this configuration, when in nasal oxygen supply mode, the reducer slows down the rotation speed of the eccentric member 1121, thereby slowing down the piston's movement speed and reducing the compressed air flow rate to decrease the oxygen flow rate. The reducer with the disconnect mechanism is prior art, and its specific structure will not be described in detail.

[0040] In some embodiments, such as Figure 1 As shown, the oxygen generating assembly 12 includes a rotary valve 121 and two molecular sieve adsorption cylinders 122. Both molecular sieve adsorption cylinders 122 are connected to the oxygen supply pipeline 13 via the rotary valve 121. Compressed air can alternately enter the two molecular sieve adsorption cylinders 122 by rotating the sliding plate inside the rotary valve 121. When compressed air flows through the rotary valve 121 and is delivered to one of the molecular sieve adsorption cylinders 122, the molecular sieve adsorption cylinder 122 adsorbs and removes nitrogen from the compressed air. When the molecular sieve adsorption cylinder 122 contains sufficient compressed air, the sliding plate of the rotary valve 121 rotates to allow compressed air to enter the other molecular sieve adsorption cylinder 122. This arrangement allows sufficient time for the compressed air to contact the adsorption medium in the molecular sieve adsorption cylinder 122, thereby improving the nitrogen adsorption and removal effect, and also increasing the oxygen generating efficiency of the oxygen generating assembly 12.

[0041] Specifically, in some embodiments, the molecular sieve adsorption cylinder 122 is filled with activated carbon to adsorb oil gas and water vapor.

[0042] Furthermore, in some embodiments, such as Figure 1 As shown, the outlet of the cylinder 111 and the inlet of the rotary valve 121 are connected by a filter 19. This configuration allows the filter 19 to filter oil vapor, water vapor, and impurities, thereby improving the nitrogen removal efficiency of the subsequent molecular sieve adsorption cylinder 122.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
