Detailed Implementation

[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0058] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0059] This application provides a vehicle seat ventilation and heating system, such as Figure 1 As shown, Figure 1 In the diagram, (1) is the top view, (2) is the front view, and (3) is the side view.

[0060] The system includes: controller 1, control motors for each seat 2, air vents for each seat 3, blower 4, air outlet baffle 5, air direction guide motor 6, ventilation and heating duct 7, air conditioning duct 8, seat air ducts for each seat 9, and seat air vents for each seat 10.

[0061] The control motor 2 corresponding to any seat is connected to the air outlet 3 of any seat; the blower 4 is connected to the ventilation and heating air duct 7 and the air conditioning air duct 8; the air conditioning air duct 8 is connected to the seat air duct 9 corresponding to each seat; the ventilation and heating air duct 7 is connected to the seat air duct 9 corresponding to each seat; the seat air duct 9 corresponding to each seat is connected to the air outlet 3 corresponding to each seat; the control motor 2 corresponding to each seat is connected to the air outlet 3 corresponding to each seat; the air direction guide motor 6 is connected to the air outlet baffle 5.

[0062] Controller 1 is used to acquire working signals, which include working type, target wind type, target air volume and seat identification. The working signals are used to transmit the wind corresponding to the target wind type to the target seat corresponding to the seat identification according to the working type and target air volume.

[0063] Controller 1 is also used to send working signals to blower 4, air direction guide motor 6, and control motor 2 corresponding to target seat;

[0064] Blower 4 is used to receive working signals and start the air supply operation according to the target wind type. The type of air generated by the blower is the target wind type.

[0065] The wind direction guide motor 6 is used to receive working signals and control the air outlet damper 5 to block the target duct according to the working type. The target duct is the air conditioning duct 8 or the ventilation and heating duct 7.

[0066] The control motor 2 corresponding to the target seat is used to receive the working signal, determine the target opening degree according to the target air volume, and control the opening degree of the air outlet 3 of the target seat to the target opening degree, so that the air generated by the blower 4 is first transmitted from the target pipe to the seat air duct 9 corresponding to the target seat, then to the seat air outlet 10 corresponding to the target seat, and then to the target seat through the air outlet with the target opening degree.

[0067] The vehicle seat ventilation and heating system provided in this application utilizes the vehicle's air conditioning function to achieve seat ventilation and heating by installing a seat air duct, an air outlet, and a control motor on each seat. Compared to installing at least one heating wire on each seat for heating, or at least one ventilation fan on each seat for ventilation, the vehicle seat ventilation and heating system provided in this application is more cost-effective. Furthermore, this application fully utilizes the vehicle's own air conditioning function, improving the utilization rate of the air conditioning system.

[0068] In one possible implementation, the system also includes a control panel 11, which displays controls for each seat under different working types and wind conditions, and the control panel 11 is connected to the controller 1 in communication.

[0069] Control panel 11 is used to determine the target airflow based on the number of times the target control is triggered when a trigger operation is received for a target control among multiple controls.

[0070] Control panel 11 is also used to generate working signals based on the seat identifier of the seat corresponding to the target control, the working type corresponding to the target control, the target wind type corresponding to the target control, and the target air volume;

[0071] Control panel 11 is also used to send operating signals to controller 1.

[0072] In this implementation, a control panel is used to generate working signals, allowing users to freely control whether to turn on the air conditioning ventilation and heating and the level of the air conditioning ventilation and heating, making the control of air conditioning ventilation and heating more flexible.

[0073] In one possible implementation, the target air volume includes a first air volume, a second air volume, and a third air volume, where the first air volume is lower than the second air volume, and the second air volume is lower than the third air volume; the number of times the target control is triggered is directly proportional to the target air volume; or, the number of times the target control is triggered is inversely proportional to the target air volume.

[0074] Optionally, if the target control is triggered once, the target airflow is determined to be the first airflow; if the target control is triggered twice, the target airflow is determined to be the second airflow; and if the target control is triggered three times, the target airflow is determined to be the third airflow. Alternatively, if the target control is triggered once, the target airflow is determined to be the third airflow; if the target control is triggered twice, the target airflow is determined to be the second airflow; and if the target control is triggered three times, the target airflow is determined to be the first airflow.

[0075] In this implementation, the airflow is controlled by controlling the number of times the target control is triggered, which makes the airflow control method more diverse and the airflow control more flexible.

[0076] In one possible implementation, the working type is to turn on the seat ventilation and heating or to turn on the air conditioning seat ventilation and heating, and the target air type is cold air or hot air.

[0077] In one possible implementation, the airflow guide motor 6 is used to control the air outlet baffle 5 to block the air conditioning duct 8 based on the working type of turning on the seat ventilation and heating; and to control the air outlet baffle 5 to block the ventilation and heating duct 7 based on the working type of turning on the air conditioning and seat ventilation and heating.

[0078] In this implementation, different channels are blocked depending on the type of work, so that the air generated by the blower passes through either the ventilation heating duct or the air conditioning duct, to achieve ventilation and heating of only the seat, or to achieve ventilation and heating of both the air conditioning and the seat.

[0079] In one possible implementation, the control motor 2 corresponding to the target seat is used to determine the target opening as a first opening based on the target air volume as a first air volume; to determine the target opening as a second opening based on the target air volume as a second air volume; and to determine the target opening as a third opening based on the target air volume as a third air volume.

[0080] Among them, the second air volume is greater than the first air volume, the third air volume is greater than the second air volume, the third opening degree is greater than the second opening degree, and the second opening degree is greater than the first opening degree.

[0081] For example, the first opening is 60 degrees, the second opening is 90 degrees, and the third opening is 180 degrees.

[0082] In this implementation, different opening degrees are determined according to the different air volumes required by the user, so as to control the opening degree of the air outlet corresponding to the seat, thereby making the seat receive different levels of airflow to achieve different degrees of ventilation and heating.

[0083] In one possible implementation, the air vent 3 of the target seat includes a first direction baffle 12 and a second direction baffle 13, with no gap between the first direction baffle 12 and the second direction baffle 13, and the first direction baffle 12 and the second direction baffle 13 are arranged opposite to each other.

[0084] The control motor 2 corresponding to the target seat is used to control the angle between the first direction baffle 12 and the second direction baffle 13 to the target opening degree.

[0085] In this embodiment, the first direction baffle can be the left side baffle and the second direction baffle can be the right side baffle; or, the first direction baffle can be the right side baffle and the second direction baffle can be the left side baffle. This application does not limit this.

[0086] In this implementation, the opening degree of the air outlet is adjusted by controlling the included angle between the first directional baffle and the second directional baffle.

[0087] In one possible implementation, the work type includes turning on the air conditioning for ventilation and heating;

[0088] The air direction guide motor 6 is used to control the air outlet damper 5 to block the ventilation and heating air duct 7;

[0089] The control motor 2 corresponding to the target seat is used to control the air outlet 10 of the target seat to close.

[0090] In this implementation, when only air conditioning ventilation and heating are turned on, the ventilation and heating duct is blocked so that the air generated by the blower is transmitted to the air conditioning duct. Then, the air outlet of the target seat is closed so that the air generated by the blower is not transmitted to the target seat, thereby achieving only air conditioning ventilation and heating.

[0091] In one possible implementation, the airflow guide motor 6 is used to control the air outlet baffle 5 to work in a third direction to block the air conditioning duct 8 when the working type is to turn on the seat ventilation and heating; and to control the air outlet baffle 5 to work in a fourth direction to block the ventilation and heating duct 7 when the working type is to turn on the air conditioning and seat ventilation and heating. The third and fourth directions are opposite.

[0092] Among them, the third direction is upward, and the fourth direction is downward.

[0093] In this implementation, the air outlet baffle is controlled to operate in a third or fourth direction to achieve seat ventilation and heating only, or air conditioning seat ventilation and heating.

[0094] In one possible implementation, the control motor 2 corresponding to each seat is used to control the opening degree between the first direction baffle 12 and the second direction baffle 13 of the air outlet corresponding to each seat. The blower 4 is connected to the ventilation and heating air duct 7 and the air conditioning air duct 8 so that the air generated by the blower 4 can pass through the ventilation and heating air duct 7 and the air conditioning air duct 8. The seat air duct 9 corresponding to each seat is connected to the ventilation and heating air duct 7, the air conditioning air duct 8 and the seat air vent 10 corresponding to each seat. The seat air vent 10 of each seat is connected to the air outlet 3 of each seat so that each seat can achieve seat ventilation or seat heating.

[0095] When the operating mode is set to "seat ventilation only," i.e., when the air conditioning is off, the blower 4 is activated to deliver cold air. The airflow direction motor 6 controls the air outlet baffle 5 to move upwards, blocking the air conditioning duct 8. This allows the cold air generated by the blower 4 to be delivered through the ventilation and heating duct 7 to the seat air duct 9 corresponding to the target seat, and then through the seat air duct 9 to the seat vent 10 of the target seat. The control motor 2 corresponding to the target seat controls the opening between the first direction baffle 12 and the second direction baffle 13 of the air outlet 3 corresponding to the target seat to the target opening degree, thereby allowing cold air to blow onto the target seat through the air outlet 3, achieving the effect of ventilation for the target seat even when the air conditioning is off.

[0096] When the operating mode is set to "seat heating only," meaning the seat heating is activated even when the air conditioning is off, blower 4 starts to deliver hot air. Airflow guide motor 6 controls the air outlet baffle 5 to move upwards, blocking the air conditioning duct 8. This allows the hot air generated by blower 4 to be transferred through ventilation and heating duct 7 to the seat duct 9 corresponding to the target seat, and then through the seat duct 9 to the seat vent 10 of the target seat. The control motor 2 corresponding to the target seat controls the opening between the first direction baffle 12 and the second direction baffle 13 of the target seat's air outlet 3 to the target opening degree, thus allowing hot air to blow onto the target seat through the air outlet 3, achieving the heating effect even when the air conditioning is off.

[0097] When the operating mode is "Air Conditioning Seat Ventilation Activated," that is, when the seat ventilation is activated while the air conditioning is on, the blower 4 is turned on to deliver cold air. The airflow direction motor 6 controls the air outlet baffle 5 to move downwards, blocking the ventilation and heating air duct 7. This allows the cold air generated by the blower 4 to be delivered through the air conditioning air duct 8 to the seat air duct 9 corresponding to the target seat, and then from the seat air duct 9 to the seat air vent 10 of the target seat. The control motor 2 corresponding to the target seat controls the opening between the first direction baffle 12 and the second direction baffle 13 of the air outlet 3 corresponding to the target seat to the target opening degree according to the target air volume. This allows the cold air to blow onto the target seat through the air outlet 3 corresponding to the target seat, achieving the effect of ventilation for the target seat when the air conditioning is on.

[0098] When the working mode is "Air Conditioning Seat Heating Activated," that is, when the seat heating is activated while the air conditioning is on, the blower 4 starts to deliver hot air. The airflow guide motor 6 controls the air outlet baffle 5 to move downwards, blocking the ventilation and heating duct 7. This allows the hot air generated by the blower 4 to be transferred through the air conditioning duct 8 to the seat duct 9 corresponding to the target seat, and then from the seat duct 9 to the seat vent 10 of the target seat. The control motor 2 corresponding to the target seat controls the opening between the first direction baffle 12 and the second direction baffle 13 of the air outlet 3 corresponding to the target seat to the target opening degree according to the target air volume. This allows the hot air to be blown onto the target seat through the air outlet 3, achieving the heating effect of the target seat when the air conditioning is on.

[0099] When the operating mode is set to "Air conditioning ventilation only," that is, when the seat ventilation is turned off while the air conditioning ventilation is on, blower 4 is activated to deliver cold air. The airflow guide motor 6 controls the air outlet damper 5 to move downwards, blocking the ventilation and heating duct 7, allowing the cold air generated by blower 4 to be output to the vehicle interior through the air conditioning duct 8, thus achieving air conditioning ventilation inside the vehicle. Since the cold air generated by blower 4 is also transmitted through the air conditioning duct 8 to the seat duct 9 corresponding to the target seat, and then from the seat duct 9 to the seat vent 10 corresponding to the target seat, and finally to the target seat through the air outlet 3 corresponding to the target seat, it is necessary to close the air outlet 3 corresponding to the target seat so that the seat is not ventilated while the vehicle interior is ventilated.

[0100] When the operating mode is set to "Air Conditioning Heating Only," that is, when the seat heating is turned off while the air conditioning heating is on, blower 4 starts to deliver hot air. The airflow guide motor 6 controls the air outlet damper 5 to move downwards, blocking the ventilation and heating duct 7, allowing the hot air generated by blower 4 to be output to the vehicle interior through the air conditioning duct 8, thus achieving air conditioning heating inside the vehicle. Since the hot air generated by blower 4 is also transferred through the air conditioning duct 8 to the seat duct 9 corresponding to the target seat, and then from the seat duct 9 to the seat vent 10 corresponding to the target seat, and finally through the air outlet 3 of the target seat, it is necessary to close the air outlet 3 corresponding to the target seat so that the seat is not heated while the vehicle interior is heated.

[0101] This application provides a method for ventilating and heating vehicle seats, such as... Figure 2 The diagram shows a flowchart of a vehicle seat ventilation and heating method provided in an embodiment of this application. Taking the method applied to a vehicle seat ventilation and heating system as an example, the method includes the following steps 201 to 206.

[0102] In step 201, the control panel acquires the working signal.

[0103] In an exemplary embodiment of this application, the control panel displays controls for each seat under different operating types and different airflow types. Operating types include turning on only seat ventilation and heating, and turning on air conditioning and seat ventilation and heating. Airflow types include cold air and hot air.

[0104] In one possible implementation, when a user wants to turn on the ventilation and heating of a target seat, the user selects the target control corresponding to the target seat. The control panel receives the trigger operation for the target control and determines the target air volume based on the number of triggers for the target control. Based on the seat identification of the target seat corresponding to the target control, the working type of the target control, the target airflow type of the target control, and the target air volume, a working signal is generated. The working signal includes the working type, the target airflow type, the target air volume, and the seat identification. The working signal is used to deliver the airflow corresponding to the target airflow type to the target seat corresponding to the seat identification according to the working type and the target airflow.

[0105] Optionally, the target airflow includes a first airflow, a second airflow, and a third airflow, wherein the first airflow is lower than the second airflow, and the second airflow is lower than the third airflow. The number of times the target control is triggered is directly proportional to the target airflow, or inversely proportional to the target airflow. That is, the more times the target control is triggered, the greater the target airflow, or the fewer times the target control is triggered, the greater the target airflow.

[0106] Optionally, the process of determining the target airflow based on the number of times the target control is triggered includes: determining the target airflow as a first airflow based on one triggering of the target control, determining the target airflow as a second airflow based on two triggering of the target control, and determining the target airflow as a third airflow based on three triggering of the target control; or, determining the target airflow as a third airflow based on one triggering of the target control, determining the target airflow as a second airflow based on two triggering of the target control, and determining the target airflow as a first airflow based on three triggering of the target control.

[0107] Optionally, if the triggering frequency for the target control is once, the target airflow can also be determined based on the pressure applied during the triggering operation on the target control. The pressure applied during the triggering operation on the target control is directly proportional to the target airflow, or inversely proportional. That is, the greater the pressure applied during the triggering operation on the target control, the greater the target airflow; conversely, the smaller the pressure applied during the triggering operation on the target control, the greater the target airflow.

[0108] For example, the process of determining the target airflow based on the pressure applied to the target control includes: determining the target airflow as a first airflow based on the pressure applied to the target control being less than a first threshold; determining the target airflow as a second airflow based on the pressure applied to the target control being not less than the first threshold and less than a second threshold; and determining the target airflow as a third airflow based on the pressure applied to the target control being not less than the second threshold. Alternatively, the target airflow is determined as a third airflow based on the pressure applied to the target control being less than the first threshold; the target airflow is determined as a second airflow based on the pressure applied to the target control being not less than the first threshold and less than the second threshold; and the target airflow is determined as a first airflow based on the pressure applied to the target control being not less than the second threshold. Wherein, the first threshold is less than the second threshold. The first and second thresholds are set based on experience or adjusted according to the implementation environment, and this application embodiment does not limit this. For example, the first threshold is 10, and the second threshold is 5.

[0109] In one possible implementation, each control corresponds to a pressure sensor, and the process of determining the pressure intensity of the trigger operation for the target control includes: determining the pressure intensity of the trigger operation for the target control through the pressure sensor corresponding to the target control.

[0110] In step 202, the control panel sends a working signal to the controller.

[0111] In one possible implementation, after obtaining the working signal in step 201 above, a working signal is sent to the controller. The working signal can be sent immediately after acquisition, or it can be sent after a target duration. This embodiment does not limit the timing of the controller sending the working signal. The target duration is set based on experience or adjusted according to the implementation environment; this embodiment does not limit this. For example, the target duration is 3 seconds.

[0112] In step 203, the controller receives working signals and sends working signals to the blower, the air direction guide motor, and the control motor corresponding to the target seat.

[0113] In one possible implementation, after receiving the working signal, the controller parses the working signal to obtain the seat identifier, determines the target seat corresponding to the seat identifier, and then sends working signals to the blower, the air direction guide motor, and the control motor corresponding to the target seat.

[0114] Optionally, the controller can send working signals to the blower, the wind guide motor, and the control motor corresponding to the target seat simultaneously, or it can send working signals to the blower, the wind guide motor, and the control motor corresponding to the target seat sequentially. This application embodiment does not limit this.

[0115] In step 204, the blower receives a working signal and starts the air supply operation according to the target wind type.

[0116] After receiving the working signal, the blower analyzes the signal to obtain the target airflow type, and then starts the air supply operation according to the target airflow type, so that the type of air generated by the blower is the target airflow type. Optionally, when the target airflow type is hot air, the blower generates hot air; when the target airflow type is cold air, the blower generates cold air.

[0117] In step 205, the wind direction guide motor receives a working signal and controls the air outlet damper to block the target duct according to the working type.

[0118] The target duct is either an air conditioning duct or a ventilation and heating duct.

[0119] In one possible implementation, after receiving the working signal, the wind direction guide motor parses the working signal to obtain the working type, and then determines the target duct based on the working type, thereby controlling the air outlet damper to block the target duct.

[0120] Optionally, when the operating mode is set to only activate seat ventilation and heating, the target duct is the air conditioning duct, which means controlling the air outlet damper to block the air conditioning duct. When the operating mode is set to activate air conditioning and seat ventilation and heating, the target duct is the ventilation and heating duct, which means controlling the air outlet damper to block the ventilation and heating duct.

[0121] In one possible implementation, the operating mode also includes only activating the air conditioning ventilation and heating. When the operating mode is set to only activate the air conditioning ventilation and heating, the target duct is the ventilation and heating duct, which means controlling the air outlet damper to block the ventilation and heating duct.

[0122] When the seat ventilation and heating are activated, the air outlet damper is controlled to move in a third direction to block the air conditioning duct, preventing airflow from the blower from passing through it. When both air conditioning and seat ventilation and heating are activated, the air outlet damper is controlled to move in a fourth direction to block the ventilation and heating duct, preventing airflow from the blower from reaching the target seat. When both air conditioning and ventilation and heating are activated, the air outlet damper is controlled to move in a fourth direction to block the ventilation and heating duct and to close the air outlet of the target seat, preventing airflow from the blower from reaching the target seat.

[0123] Among them, the third direction is upward, and the fourth direction is downward.

[0124] In step 206, the control motor corresponding to the target seat receives the working signal, determines the target opening degree according to the target air volume, and controls the opening degree of the air outlet of the target seat to be the target opening degree.

[0125] In one possible implementation, after receiving the working signal, the control motor corresponding to the target seat analyzes the signal to obtain the target air volume. Based on the target air volume, the target opening is determined, and the opening of the air outlet of the target seat is controlled to the target opening. This allows the air generated by the blower to be transmitted through the target duct to the seat air guide duct of the target seat, then through the seat air guide duct to the seat air vent of the target seat, and finally through the air outlet with the target opening to the target seat.

[0126] The process of determining the target opening degree based on the target air volume includes: determining the target opening degree as a first opening degree based on the target air volume as a first air volume; determining the target opening degree as a second opening degree based on the target air volume as a second air volume; and determining the target opening degree as a third opening degree based on the target air volume as a third air volume. The second air volume is greater than the first air volume, the third air volume is greater than the second air volume, the third opening degree is greater than the second opening degree, and the second opening degree is greater than the first opening degree. For example, the first opening degree is 60 degrees, the second opening degree is 90 degrees, and the third opening degree is 180 degrees.

[0127] Optionally, the air vent corresponding to the target seat includes a first direction baffle and a second direction baffle, and there is no gap between the first direction baffle and the second direction baffle. The first direction is either the left or right side, and the second direction is either the left or right side, but a different direction from the first direction. The process of controlling the opening of the air vent corresponding to the target seat to a target opening includes: controlling the angle between the first direction baffle and the second direction baffle to the target opening. For example, if the target opening is 60 degrees, then the angle between the first direction baffle and the second direction baffle is controlled to be 60 degrees. If the target opening is 90 degrees, then the angle between the first direction baffle and the second direction baffle is controlled to be 90 degrees. If the target opening is 180 degrees, then the angle between the first direction baffle and the second direction baffle is controlled to be 180 degrees.

[0128] In one possible implementation, each seat also has a corresponding seat vent. The seat vent of any seat is connected to the seat air duct of any seat and the air outlet of any seat, so that the air generated by the blower is transmitted through the target duct to the seat air duct of the target seat, then through the seat vent of the target seat to the air outlet of the target seat, and finally through the air outlet of the target seat to the target seat, so as to achieve seat ventilation and heating.

[0129] It should be noted that steps 204, 205, and 206 can be executed simultaneously or sequentially. This application embodiment does not limit the execution order of steps 204, 205, and 206.

[0130] The vehicle seat ventilation and heating method provided in this application utilizes the vehicle's air conditioning function by installing a seat air duct, an air outlet, and a control motor on each seat to achieve seat ventilation and heating. Compared to installing at least one heating wire on each seat for heating, or at least one ventilation fan on each seat for ventilation, the vehicle seat ventilation and heating system provided in this application is more cost-effective. Furthermore, this application fully utilizes the vehicle's own air conditioning function, improving the utilization rate of the air conditioning system.
