Description

Technical Field

[0001] The utility model belongs to the technical field of indoor air treatment, and relates to an air management system, in particular to a single cockpit air management system. Background Art

[0002] In most electrically driven motor vehicles, in order to achieve the highest possible driving range, it is very necessary to save as much energy as possible during the vehicle's driving process. Usually, due to the requirements for vehicle comfort, the driver and passengers can adjust the air temperature and humidity in the passenger compartment of the motor vehicle with the help of an air conditioning device.

[0003] By controlling the air conditioning device (adjusting the internal / external circulation mode), increasing the working duration of the internal circulation mode - in the internal circulation operation, the air in the passenger compartment is recycled and air-conditioned (heated or cooled), so that the air conditioning device for air-conditioning the passenger compartment introduces and heats (in winter) or cools (in summer) as little fresh air as possible from the external environment of the motor vehicle. By using the internal circulation mode to recycle the air in the cabin to adjust the temperature and humidity of the air in the cabin, the desired energy saving is achieved. However, in the above-mentioned recycling operation for air-conditioning the passenger compartment, the water vapor contained in the exhaled gas of the passengers may cause the humidity in the passenger compartment to continuously rise, which may cause the window glass of the motor vehicle (for example, the windshield or side window) to fog up, bringing unpredictable dangers to the vehicle drivers and passengers. If the air conditioning device continuously turns on the defogging mode to reduce the humidity in the cabin, this will instead increase the power consumption of the air conditioning device and cannot achieve the purpose of energy saving of the vehicle thermal management system. In addition, the carbon dioxide contained in the exhaled gas of the driver and passengers may also accumulate in the passenger compartment, causing the driver to feel sleepy during driving, bringing potential dangers to the normal operation of the vehicle. This is related to the driving safety of the vehicle and the health of the driver and passengers, and it is necessary to prevent and reduce the occurrence of this situation, avoiding that due to the too high carbon dioxide concentration in the air of the passenger compartment, the driver's concentration ability may be greatly reduced, bringing potential dangers to the normal operation of the vehicle. Summary of the Invention

[0004] The purpose of the utility model is to provide an air management system, in particular to provide a single cockpit air management system. By purifying the air inside the vehicle, when the vehicle is in the internal circulation mode, the water vapor, carbon dioxide and harmful gases in the vehicle air are filtered and purified, reducing the harmful gases in the vehicle, improving the air health index and comfort of the cockpit, avoiding fogging during vehicle driving, and ensuring that the driver and passengers will not be fatigued and sleepy due to too high a concentration of carbon dioxide, reducing the number of times the vehicle turns on the external circulation, thereby reducing the energy consumption of the air conditioning system and greatly improving the driving range of the vehicle.

[0009] The heater is used to start when the adsorption unit reaches saturation and provide the heat required for the regeneration of the adsorption unit; the heater selects a PTC heater.

[0010] The control system is used to control the opening and closing of the air outlet channel and switch to control the adsorption mode M1 and the regeneration mode M2. When the air outlet channel is opened, that is, when the air outlet flap is opened, the air management system enters the adsorption mode M1; when the air outlet channel is closed, that is, when the air outlet flap is closed, the air management system enters the regeneration mode M2.

By using this arc-shaped air guiding structure, the air intake direction of the air duct can be optimized from the normal direction to the windward surface, making it easier for air to enter the air duct. In addition, the air volume entering the system is controlled by modifying the windward area of this structure on the air duct inside the air conditioner pipeline. The system air inlet is integrally formed with one end of the first housing.

[0014] Further, the adsorption unit includes an adsorption box filled with an adsorbent. The adsorbent can be selected as a single-function adsorbent according to customer requirements or configured as a multi-functional combination according to customer requirements. The adsorption box is in a "U" shape, semi-circular shape, or "V" shape. The inner side and the outer side of the adsorption box serve as the air inlet surface and the air outlet surface respectively, and are both provided with a plurality of breathable mesh holes. The size of the adsorption unit is adapted to the size of the cavity. The adsorption unit further includes a top cover assembled on the top of the adsorption box, and the top cover is fixedly connected to the inner wall of the first housing.

[0015] Further, a first sealing structure is clamped between the top cover and the adsorption unit. A second sealing structure is provided in a ring shape on the inner wall of the first housing. The first sealing structure and the second sealing structure are sealing rubber strips. The outer edge of the first sealing structure extends outward and is in sealing contact with the second sealing structure, playing a role in separating the gas before treatment and the gas after treatment.

[0016] Further, a heater installation hole position is also provided on the top cover, and the heater is arranged in the heater installation hole position. A heater fixing point is provided in the heater installation hole position, and the heater fixing point fixedly assembles the heater. The heater includes a protective housing with an inner cavity, heating sheets arranged in the inner cavity, heater installation and fixing points arranged on both sides of the protective housing, and a heating power supply electrically connected to the heating sheets. After the heater is installed in the heater installation hole position, the heater is fixed on the top cover by screws passing through the heater installation and fixing points. A plurality of ventilation holes are opened on the top surface and the bottom surface of the protective housing, and the top surface and the bottom surface serve as the air inlet surface and the air outlet surface respectively. The air inlet surface of the adsorption unit surrounds the air outlet surface of the heater. This design structure maximally improves the heat transfer ability of the PTC heater to the adsorption unit during operation.

[0017] Further, the cover further includes sealing plate rings and a system air outlet provided at both ends of the air outlet passage.

The sealing plate ring is tightly connected to the end opening of the second housing by screws or welding to achieve the sealing of the system and the outside.

[0018] Further, the control system includes a drive motor, an air outlet flap, and an air outlet flap coupling that rotatably connects the drive motor and the air outlet flap.

The motor positioning and mounting structure includes a pin shaft structure or a screw structure to achieve the positioning and mounting of the drive motor.

[0019] Further, the air outlet flap includes an air outlet flap body, a connecting rod body fixedly connected to the air outlet flap body, a coupling docking port fixedly connected to one end of the connecting rod body, and a baffle perpendicularly fixed to and connected to the edge of the air outlet flap body; air outlet flap mounting holes are oppositely provided on the outer wall of the air outlet passage. The connecting rod body passes through the air outlet flap mounting hole on one side. One end of the air outlet flap coupling passes through the air outlet flap mounting hole on the other side and docks with the coupling docking port. The other end of the air outlet flap coupling is connected to the drive motor.

[0020] Further, a system exhaust port is provided on the outer wall of the air outlet passage. The system exhaust port is used to discharge the regenerated high-temperature and high-humidity gas out of the vehicle; ribs are provided on the inner wall of the air outlet passage. The air outlet flap cooperates with the ribs. When the air outlet flap seals and covers the system air outlet, at this time, the air outlet flap body is clamped between the ribs, the air outlet passage is closed, and the system exhaust port is opened, and the gas is discharged from the system exhaust port; when the air outlet flap rotates until the baffle abuts against one of the ribs, at this time, the baffle just covers the system exhaust port, the air outlet passage is opened, the system exhaust port is closed, and the gas is output from the system air outlet.

[0021] Furthermore, an extension pipe is connected to the system air outlet and the system exhaust outlet. A gas concentration detection sensor is provided on the extension pipe. The sensor is used to monitor the concentration information of carbon dioxide, water vapor, and harmful gases. The sensor includes a carbon dioxide sensor, a water vapor sensor, a formaldehyde sensor, a VOC sensor, and other sensors that meet customer requirements. A temperature sensor is provided on the heater. The temperature sensor can effectively monitor the temperature change of the heater. After the sensor detects the temperature signal, when the temperature is too high, the external execution system cuts off the power supply of the heater to prevent accidents caused by overheating of the heater and failures caused by heater malfunctions, ensuring the safe operation of the heater during the heating process and preventing overheating risks.

[0022] Furthermore, the air management system also has an intelligent pre-regeneration function, which can enter the regeneration mode in advance according to the vehicle's adaptation conditions (such as charging, waiting to start, etc.). Specifically, when charging, the vehicle is connected to an external power supply, and the external power supply regenerates the adsorption unit in the air management system, thus saving the vehicle's own power and avoiding affecting the endurance.

[0023] With the help of the control system, the adsorption unit of the air management system can be switched from M1 to M2 according to the concentration information of carbon dioxide, water vapor, or harmful gases of the sensor on the extension pipe. At the same time, the external power supply of the heater is turned on, and the heating device starts to work, providing the high-temperature gas required for the regeneration of the adsorption unit and discharging the regenerated air to the external environment of the closed air volume through the system exhaust outlet. At the same time, the temperature monitoring device monitors the temperature of the heater to ensure the safety of the air management system under M2. And the internal / external circulation control device turns on the external circulation channel to adjust the mixing ratio of the external air according to the concentration information of carbon dioxide, water vapor, or harmful gases in the closed air volume to ensure that the concentration of carbon dioxide, water vapor, or harmful gases in the closed air volume is in a safe state. Conversely, it can be switched from M2 to M1 according to the information of the sensor on the extension pipe. At the same time, the internal / external circulation control device closes the external circulation channel to reduce the heat loss in the closed air volume for the purpose of energy conservation.

[0024] The above-mentioned internal / external circulation control device and the motor are both connected to the PCL controller. The corresponding sensor gives a signal to the PCL controller, sending the concentration information of the corresponding substance in the closed air volume to the PCL controller to realize the opening and closing of the internal / external circulation control device and the switching between M1 and M2.

[0025] Compared with the prior art, the present utility model has the following beneficial effects:

[0026] 1) The present utility model proposes to control the humidity, carbon dioxide concentration, and harmful gases in the air inside the cockpit when the automotive air conditioner is in a fully recirculated state, so as to further improve the adsorption of harmful gases inside the cockpit, control the air quality inside the cabin, achieve energy savings, enhance the vehicle's endurance, and fill the market gap.

[0027] 2) The present utility model utilizes the property of the adsorbent material in the adsorption unit to adsorb at low temperature and desorb at high temperature, and evolves and manages the air quality inside the cockpit through the adsorption mode and the regeneration mode. In the adsorption mode, the system mainly removes carbon dioxide, water vapor, and harmful gases in the enclosed air volume through the adsorption unit. This mode operates continuously during normal vehicle operation or when the vehicle is occupied to ensure the comfort and safety of the interior environment. When the adsorption unit reaches saturation and can no longer effectively adsorb pollutants, the system will automatically switch to the regeneration mode to desorb the adsorbed pollutants and realize the regeneration of the adsorption unit.

[0028] 3) The present utility model also has an intelligent pre-regeneration function, which can enter the regeneration mode in advance according to the vehicle's applicable working conditions (such as charging, waiting to start, etc.) to complete the regeneration work of the adsorption unit. When the vehicle needs to enter the adsorption mode, the system is already ready and can start working immediately without waiting for the regeneration process to complete, thereby improving the overall efficiency and user experience, effectively extending the service life of the adsorption unit, and further enhancing the economy and practicality of the system.

[0029] 4) The present utility model is designed as a single filtration system. Compared with multiple filtration components on the market, it reduces the external dimensions of the system, improves the system's compatibility, reduces the use of component consumables, lowers the manufacturing cost, and enhances the market competitiveness.

[0030] 5) The present utility model fully considers safety and energy conservation. The temperature monitoring device ensures the safe progress of the heating process and prevents the risk of overheating. Description of the Drawings

The air management system is in M1 ( Figure 7When in state M1, the air duct 15 introduces the gas in the positive pressure area of the air conditioner into the system air inlet 9. After passing through the heater 4 (at this time, the heater 4 is in a non-working state), it reaches the adsorption unit 3 for air dehumidification. The dried air flows through the system air outlet 12 and then returns to the air conditioner system and is distributed to various areas of the cab according to requirements; when the air management system is in M2 ( Figure 9 ), the air duct 15 introduces the dry outside air in the positive pressure area of the air conditioner, or the mixed air of the outside and inside of the vehicle, into the system air inlet 9. After passing through the heater 4 (at this time, the heater 4 is in a working state), the regeneration air will be heated to the set temperature, and then the hot air is transported to the adsorption unit 3 to heat the adsorption material, so as to realize the function of material regeneration.

[0057] This air management system is combined with the internal / external circulation control device. With the help of the control system, the adsorption unit 3 can be switched from M1 to M2 according to the carbon dioxide, water vapor or harmful gas concentration information of the sensor on the extension pipe. At the same time, the external power supply of the heater 4 is turned on, and the heating device starts to work, providing the high-temperature gas required for the regeneration of the adsorption unit 3, and discharging the regenerated air to the external environment of the closed air volume through the system exhaust port. At the same time, the temperature monitoring device monitors the temperature of the heater 4 to ensure the safety of the air management system under M2, and the internal / external circulation control device turns on the external circulation channel to adjust the mixing ratio of the external air according to the carbon dioxide, water vapor or harmful gas concentration information in the closed air volume, so as to ensure that the concentration of carbon dioxide, water vapor or harmful gas in the closed air volume is in a safe state. Among them, the above-mentioned internal / external circulation control device and the drive motor 6 are both connected to the PCL controller, and the corresponding sensor gives a signal to the PCL controller, sending the concentration information of the corresponding substance in the closed air volume to the PCL controller, realizing the opening and closing of the internal / external circulation control device and the switching between M1 and M2. Conversely, it can be switched from M2 to M1 according to the information of the sensor on the extension pipe. At the same time, the internal / external circulation control device closes the external circulation channel to reduce the heat loss in the closed air volume, so as to achieve the purpose of energy saving.

[0058] In some specific embodiments, the air management system also has an intelligent pre-regeneration function, which can enter the regeneration mode in advance according to the vehicle's adaptation working conditions (such as the motor vehicle charging working condition, the to-be-started working condition, etc.) to complete the regeneration work of the adsorption unit. In this way, when the vehicle needs to enter the adsorption mode, the system is already ready and can start working immediately without waiting for the regeneration process to be completed, thus improving the overall efficiency and user experience.
