[0037] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] Figure 1 This is a schematic block diagram of an airflow control device provided in an embodiment of the present application, see Figure 1 As shown, the airflow control device 100 includes at least one electrode array 101 and an electrode grid 102; wherein,

[0039] Each electrode array 101 is disposed on the inner wall of the outlet of the air flow channel of the vehicle, and is used to form a non-uniform electrostatic field; wherein the non-uniform electrostatic field induces ionization of gas molecules to charge the air flow in the air flow channel, and drives the charged air flow to move in a predetermined direction;

[0040] The electrode grid 102 is disposed outside the air flow channel and is used to provide a loop for a non-uniform electrostatic field.

[0041] In the embodiment of the present application, the electrode array 101 includes a plurality of high-voltage electrodes, and a high-intensity non-uniform electrostatic field is formed by applying an adjustable voltage of 5 kilovolts (kV) to 20 kV to the high-voltage electrodes.

[0042] In an embodiment of the present application, the non-uniform electrostatic field induces the ionization of gas molecules to form positive and negative ion groups. The positive and negative ion groups attach to the neutral molecules in the air flow in the air flow channel to form charged current. The non-uniform electrostatic field generates an electric field force (F1=qE) to drive the charged current to move in a preset direction. In this way, no mechanical air guide plate intervention is required.

[0043] Here, the preset direction may be a direction indicated by an instruction, such as a direction of a passenger position or a direction of a non-passenger position.

[0044] Here, the electric field force refers to the interaction between the charges in the electric field and the electric field, that is, the force exerted on any charged body in the electric field. F1 represents the electric field force, q represents the amount of charge, which can be positive or negative (determines the direction of the force), and E represents the electric field. Figure 2 This is a schematic diagram of a charged current moving under the action of an electric field force provided by an embodiment of the present application, such as Figure 2 As shown, the charged current moves at a certain deflection angle.

[0045] In an embodiment of the present application, an electrode array 101 can be set on each air flow channel in the vehicle, or the electrode array 101 is set on part of the air flow channels, and one electrode array 101 corresponds to one air flow channel. Then, the number of electrode arrays 101 is less than or equal to the number of air flow channels in the vehicle.

[0046] In the embodiment of the present application, the number of electrodes included in the electrode arrays provided on different air flow channels, the arrangement of the electrode arrays, and the types of electrodes included in the electrode arrays may be different or the same.

[0047] In the embodiment of the present application, multiple groups of independent electrode arrays 101 are set at different positions of the air outlet corresponding to the air flow channel to control the temperature and speed of the air flow in different areas (such as sending cold air to the upper layer and warm air to the lower layer).

[0048] In the embodiment of the present application, the electrodes included in the electrode array include but are not limited to annular electrodes, spiral electrodes, needle electrodes, annular corrosion-resistant electrodes, and spiral corrosion-resistant electrodes. The electrodes can be made of materials such as graphene and titanium alloy.

[0049] In the embodiment of the present application, the air flow channel of the vehicle includes but is not limited to the air outlet channel of the temperature adjustment device in the vehicle, or the air outlet channel of the seat ventilation system in the vehicle.

[0050] The present application can combine the hybrid control of traditional mechanical air guide plates and airflow control devices 100, for example, by driving the air guide plates to coarsely adjust their direction through a small motor, and then using the electrostatic field to fine-tune the airflow trajectory. In this way, it is compatible with existing mechanical structures, reduces the cost of technology replacement, and retains the characteristics of electrostatic precision control, which is suitable for cost-sensitive mid- and low-end models.

[0051] In the embodiment of the present application, the electrode grid 102 is connected to a grounding device of a vehicle. The electrode grid 102 includes a plurality of grounding electrodes, which are arranged outside the air outlet corresponding to the air flow channel.

[0052] In the embodiment of the present application, the surface of the electrode grid 102 is covered with a microporous metal mesh (pore size ≤ 2 mm), which can provide a circuit for the external electric field and adsorb charged particles (such as dust), thereby having both airflow diffusion and safety protection functions.

[0053] In the embodiment of the present application, the transportation vehicle includes a motor vehicle, a car, an airplane, a train, a submarine, a helicopter, a ship, a boat, an aircraft or any other transportation vehicle.

[0054] In the embodiment of the present application, the airflow is actively controlled by a non-uniform electrostatic field, thereby achieving directional movement of the airflow and solving the problem of uneven airflow dispersion; moreover, the use of a non-uniform electrostatic field to control the airflow can replace the mechanical air guide structure in the related technology, so that the adjustment angle of the airflow is no longer restricted by the mechanical air guide plate, thereby expanding the adjustable angle of the airflow, reducing the resistance of the air guide plate, and reducing the energy consumption of the air-conditioning system; and the electric field force of the non-uniform electrostatic field constrains the diffusion of the airflow, reduces the collision with the wall of the air outlet, and effectively suppresses the turbulence of the airflow.

[0055] Figure 3 This is a schematic block diagram of an airflow control device provided in an embodiment of the present application, see Figure 3 As shown, the airflow control device 100 includes at least one electrode array 101, an electrode grid 102 and a control unit 103; wherein,

[0056] Each electrode array 101 is disposed on the inner wall of the outlet of the air flow channel of the vehicle, and is used to form a non-uniform electrostatic field; wherein the non-uniform electrostatic field induces ionization of gas molecules to charge the air flow in the air flow channel, and drives the charged air flow to move in a predetermined direction;

[0057] The electrode grid 102 is disposed outside the air flow channel and is used to provide a loop for a non-uniform electrostatic field.

[0058] The control unit 103 is configured to control the intensity and direction of the non-uniform electrostatic field by adjusting the voltage applied to the electrode array 101 or the polarity of the electrodes in the electrode array 101 .

[0059] Figure 4 This is a three-dimensional structural entity diagram of an airflow control device provided by this application, such as Figure 3 As shown, the control unit 103 is connected to the electrode array 101 via a bus 301 .

[0060] In the embodiment of the present application, the control unit 103 is used to adjust the electrostatic field intensity and direction in real time to match different wind speeds, temperatures and passenger position requirements.

[0061] Figure 5 This is a circuit diagram of a simple airflow control device provided by this application, such as Figure 5 As shown, the simple airflow control device includes a protective resistor R1, an adjustable resistor R2, an air-conditioning outlet electrode plate, a switch and a power supply; by adjusting the adjustable resistor R2, the voltage of the air-conditioning outlet electrode plate is adjusted.

[0062] In the embodiment of the present application, the control unit 103 includes: sensors (such as temperature and humidity sensors, PM2.5 sensors, infrared position sensors) and a microcontroller unit (MCU).

[0063] In the embodiment of the present application, if the vehicle is a car and the air flow channel is an air outlet channel of an onboard air conditioner, then the control unit 103 is linked to the air conditioning system via an onboard controller area network (CAN) bus.

[0064] In an embodiment of the present application, the non-uniform electrostatic field drives the charged particles in the charged air flow to be adsorbed to the electrode grid 102, thereby reducing the pollution at the outlet of the air flow channel; the control unit 103 is also used to control the first voltage generating device to apply voltage to the electrode grid 102 to bounce off the particles; wherein the voltage applied to the electrode grid 102 is opposite to the voltage applied to the electrode array 101.

[0065] In the embodiment of the present application, dust particles (PM2.5, pollen, etc.) in the air flow are charged in the electrostatic field (corona discharge effect) and are subjected to the Coulomb force (F2 = k·q1q2 / r 2 ) drives adsorption to the electrode grid 102, with a purification efficiency of ≥90% for charged particles. Wherein, Coulomb force represents the interaction force between two stationary point charges, F2 represents the Coulomb force, k represents the electrostatic force constant, q1 and q2 represent the charges of the two point charges, and r represents the distance between the two charges.

[0066] In an embodiment of the present application, the control unit 103 can send an instruction to the first voltage generating device for periodically applying a reverse voltage to the electrode grid 102, so that the first voltage generating device periodically applies a reverse voltage to the electrode grid 102 (such as applying a -5kV pulse every 24 hours); or, when the control unit 103 monitors that the number of particulate matter adsorbed in the electrode grid 102 is greater than a preset number, it instructs the first voltage generating device to apply a reverse voltage to the electrode grid 102, so that the first voltage generating device applies a reverse voltage to the electrode grid 102 in a timely manner, that is, the reverse voltage can be applied periodically or when a certain condition is met.

[0067] In the embodiment of the present application, the control unit 103 can also automatically trigger a reverse voltage pulse by detecting the air humidity and use condensed water to flush the dust on the electrode surface, thereby solving the problem of decreased efficiency caused by dust accumulation on the electrode in a high humidity environment.

[0068] In the embodiment of the present application, electrostatic dust removal and air flow guidance are integrated into the same device. By applying a reverse voltage to the electrode grid 102, particles or dust in the electrode grid 102 can be automatically ejected, thereby improving the air outlet efficiency.

[0069] In the embodiment of the present application, the control unit 103 is further configured to monitor the amount of adsorbed particles in the electrode grid 102 , and output a cleaning prompt message if the amount is greater than a preset amount.

[0070] In the embodiment of the present application, a cleaning reminder is triggered when the electrostatic adsorption is fully loaded, thereby extending the service life of the electrode grid 102.

[0071] In the embodiment of the present application, the output of cleaning reminder information can include but is not limited to outputting color, outputting text, outputting sound, outputting graphics, outputting symbols, outputting pictures, etc., all of which are convenient for prompting cleaning.

[0072] In an embodiment of the present application, the control unit 103 is also used to monitor the current (in real time). If the current is abnormal, the second voltage generating device is controlled to stop applying voltage to the electrode array 101 and output a warning message; wherein the current is formed by the directional movement of free charges in a non-uniform electrostatic field.

[0073] In the embodiment of the present application, the first voltage generating device and the second voltage generating device may be the same device or two different devices.

[0074] In the embodiment of the present application, the control unit 103 controls the second voltage generating device to stop applying a voltage of 5 to 20 kV (which can be understood as a forward voltage) to the electrode array 101 .

[0075] In the embodiment of the present application, the output warning information can include but is not limited to output color, output text, output sound, output graphics, output symbols, output pictures, etc., all of which are convenient for warning.

[0076] In the embodiment of the present application, the current abnormality includes short circuit or leakage (current>5mA).

[0077] In an embodiment of the present application, a safety protection mechanism is provided to monitor the electrode current in real time. If a short circuit or leakage is detected, the high-voltage output is immediately cut off and an alarm is triggered, thereby ensuring the safety of passengers and the driver.

[0078] In the embodiment of the present application, the control unit 103 is also used to adjust the voltage gradient applied to the electrode array 101 so that the airflow in the airflow channel is continuously deflected from the first angle to the second angle, thereby achieving infinitely precise control of the airflow.

[0079] In the embodiment of the present application, the first angle can be 0°, where 0° is relative to the horizontal plane, and the second angle can be 60°, where 60° is relative to the horizontal plane. Of course, the second angle can be any angle less than 60°. It can be seen that the mechanical air deflector in the related art only supports 15° to 30° segmented adjustment, while the airflow control device of the present application achieves continuous deflection from 0° to 60°, expanding the adjustable angle.

[0080] In an embodiment of the present application, the control unit 103 is further used to adjust the intensity and direction of the non-uniform electrostatic field through first information; wherein the first information includes one or more of the following: environmental parameters within the vehicle; the position of the object within the vehicle; voice or gesture control instructions.

[0081] In the embodiment of the present application, the control unit 103 adjusts the intensity and direction of the non-uniform electrostatic field through the first information to adjust the movement direction, deflection angle and movement speed of the charged current in the non-uniform electrostatic field. In this way, the intensity and direction of the non-uniform electrostatic field are dynamically controlled through multi-mode parameters.

[0082] In the embodiment of the present application, environmental parameters include temperature, humidity, and air quality, which are detected by temperature and humidity sensors and PM2.5 sensors.

[0083] In the embodiment of the present application, the position of the object in the vehicle is detected by an infrared sensor.

[0084] This application uses infrared sensors to detect passenger positions and PM2.5 sensors to monitor air quality. The MCU in the control unit 103 dynamically adjusts the electric field strength or direction based on the number of detections.

[0085] Here, adjusting the electric field strength or direction is achieved by adjusting the voltage applied to the electrode array or the polarity of the electrodes included in the electrode array (eg, increasing the voltage to 15 kV when PM2.5 exceeds the standard).

[0086] Here, biosensors are used to identify passenger gestures or body temperature, and dynamically adjust the electrostatic field deflection angle and wind speed.

[0087] In the embodiment of the present application, the electrodes in the electrode array 101 are distributed in a ring or spiral shape in the inner wall. In this way, the ring or spirally distributed electrode array 101 can assist the electrode array 101 in forming a non-uniform electrostatic field in the air flow channel.

[0088] In the embodiment of the present application, the electrode grid 102 is detachable. Thus, the detachable electrode grid 102 ensures that the electrode grid 102 can be cleaned in a timely manner.

[0089] The airflow control device provided by this application integrates three functions: electrostatic dust removal, airflow guidance, and noise reduction. It actively controls airflow through an electrostatic field, replacing traditional mechanical air guide structures such as air guides and independent filters, reducing volume by more than 30%. Furthermore, the resistance of the electrostatically driven airflow is reduced by 50% compared to mechanical air guides, reducing air conditioning system energy consumption by 8%-12%. Furthermore, the electric field force constrains airflow diffusion, reducing collisions with the outlet wall, reducing the standard deviation of the airflow velocity distribution by 40%, and reducing noise by 15-20dB(A).

The method includes:

[0093] Step 601: Invoke a control unit to control the intensity and direction of a non-uniform electrostatic field by adjusting the voltage applied to the electrode array or the polarity of the electrodes in the electrode array.
