Therefore, the scenario of users smoking in vehicles is receiving increasing attention from OEMs. Currently, vehicles are a major means of transportation. How to satisfy smokers while protecting non-smokers from the harm of secondhand smoke, and simultaneously providing a good in-vehicle environment, has become a major research and development challenge.

[0003] However, current methods primarily utilize the vehicle's air conditioning system and open windows to alter airflow and expel harmful gases produced by smoking. From a user experience perspective, this approach has significant drawbacks in certain scenarios. Particularly at high speeds, opening windows increases noise and creates strong, turbulent airflow, easily causing cigarette ash to fly everywhere and significantly impacting the in-car environment. Furthermore, in extreme weather conditions such as rain, snow, or low temperatures, it can negatively affect the health of passengers, especially the elderly and children. Therefore, based on the above, there is an urgent need for an in-car smoke extraction device and control method that can quickly remove smoke while providing a comfortable in-car environment for non-smokers – a technical problem that needs to be solved.

[0055] The following is combined Figure 1 The first embodiment of this application will be described in detail.

[0056] Example 1

[0057] An in-vehicle smoke exhaust device includes: at least one exhaust structure 1 arranged inside the vehicle; each exhaust structure 1 includes: an exhaust duct 11 connecting the interior and exterior spaces of the vehicle; wherein, a retractable structure 2 is provided at one end of the exhaust duct 11 inside the vehicle, and an adjustable solenoid valve 12 is provided at the other end of the exhaust duct 11; wherein, a drive device corresponding to the retractable structure 2 is also provided inside the exhaust duct 11 outlet, which is driven and connected to the retractable structure 2; a blower structure 3 is provided at the end of the retractable structure 2 away from the drive device; and further includes: a central control module electrically connected to the drive device, the blower structure 3, and the solenoid valve 12 respectively; the central control module is used to execute a corresponding control strategy according to the smoke concentration inside the vehicle.

[0058] The solenoid valve 12 is provided with a mounting seat 4 for mounting the solenoid valve 12 housing on the outer surface of the vehicle.

[0059] Furthermore, the exhaust structure 1 is arranged in the roof of the vehicle; wherein, one end of the exhaust duct 11 is located in the roof of the vehicle, and the other end can be located on the outside of the vehicle.

[0060] Specifically, this application utilizes multiple exhaust structures 1 arranged inside the vehicle to efficiently and intelligently expel harmful gases generated inside the vehicle, thereby ensuring the air quality and environmental hygiene of the vehicle interior, and guaranteeing the user's driving experience and comfort during driving.

[0061] Furthermore, the telescopic structure 2 includes: a multi-stage telescopic rod 21 with a hollow structure that is driven and connected to the driving device; the multi-stage telescopic rod 21 includes at least two relatively slidably connected first hollow rods 210 and second hollow rods 211; wherein, the first hollow rod 210 is sleeved on the outside of the second hollow rod 211; one end of the first hollow rod 210 is inserted into the exhaust duct 11 and is slidably connected to the exhaust duct 11, and the other end is slidably connected to one end of the second hollow rod 211; the other end of the second hollow rod 211 is connected to the blower structure 3; wherein, the output end of the driving device is fixedly connected to the inner wall of the second hollow rod 211.

[0062] In this embodiment, the driving device is a linear actuator motor electrically connected to the central control module, and the multi-stage telescopic rod 21 is a two-stage telescopic rod. The output shaft of the linear actuator motor can extend out of the exhaust duct 11 and connect to the multi-stage telescopic rod 21. The output end of the linear actuator motor is fixed to the inner wall of the second empty rod 211 and can drive the second empty rod 211 and the first empty rod 210 to perform linear motion, thereby moving the blower structure 3.

[0063] Specifically, the multi-stage telescopic rod 21 designed in this application can not only adjust the position of the blower structure 3 according to the smoke concentration in the vehicle to achieve a rapid and intelligent smoke exhaust function, but also use the multi-stage telescopic rod 21 itself as a pipe connection part, saving space occupancy and having high practicality and stability.

[0064] Furthermore, the blower structure 3 includes: an air duct 31 communicating with the second hollow rod 211, a turbine housing 32 communicating with the air duct 31, a fan 34 disposed inside the turbine housing 32, and a fan motor 33 disposed in the middle of the fan 34 and electrically connected to the central control module; the turbine housing 32 is a hollow structure with an opening at the lower end, wherein the lower opening of the turbine housing 32 is arranged downward; the outlet of the air duct 31 is located on the side wall of the turbine housing 32; the fan motor 33 is fixed inside the turbine housing 32 through a fan motor housing.

[0065] Specifically, this application drives a fan motor to rotate the fan, thereby expelling harmful gases from the vehicle interior through the air duct 31, the multi-stage telescopic rod, and the air duct to the outside of the vehicle, thus ensuring the air quality inside the vehicle.

[0066] It is understood that the in-vehicle smoke exhaust device and method provided in this application are applicable to special environments. During application, there is no need to open the car windows. Through intelligent control, harmful gases inside the car can be quickly exhausted outside the car, thus improving the user's driving experience and comfort.

[0067] Secondly, this application provides a method for controlling in-vehicle smoke extraction, comprising the following steps:

[0068] Step S1: Based on the vehicle type and interior space area, divide the vehicle interior space into multiple first spaces; wherein each first space is equipped with at least one exhaust structure 1;

[0069] Step S2: Obtain the smoke concentration value inside each first space;

[0070] Step S3: Compare the smoke concentration value of each first space with the preset value, and execute the corresponding control strategy based on the comparison result.

[0071] Specifically, this application can divide the vehicle interior space into multiple first spaces based on the area of ​​the interior space and vehicle model information, thereby enabling the arrangement of the exhaust structure according to different vehicle models. Furthermore, it can facilitate the accurate acquisition of smoke concentration in different spaces within the vehicle. By detecting the smoke concentration in a single space, the exhaust structure 1 can quickly and efficiently exhaust harmful gases from the space.

[0072] For example, taking an MPV as an example, the driver's cab and the front passenger cab are combined into one space, and the passenger space in the last two rows is divided into two first spaces by the rear side of the single row of seats. Within each first space, two smoke concentration sensors are installed to collect smoke concentration values, thereby accurately obtaining smoke concentration information for each space. Preferably, smoke concentration sensors are installed at the top of each first space near the turbine housing, and also on the vehicle interior panel at shoulder height when the passenger is seated upright.

[0073] Furthermore, by comparing the smoke concentration value in each first space with the preset value, the smoke concentration level of each space is determined from within, and corresponding control strategies are adopted accordingly. This not only has a high degree of intelligence, but also can quickly expel harmful gases, improving the user's driving experience and comfort.

[0074] Furthermore, the step of comparing the smoke concentration value of each first space with a preset value, and executing a corresponding control strategy based on the comparison result, specifically includes:

[0075] S30: Real-time acquisition of the smoke concentration value with the highest concentration among all smoke concentration values ​​in the first space;

[0076] S31: If the maximum smoke concentration is greater than or equal to the preset value, then the control strategy is triggered and the exhaust structure is activated.

[0077] Furthermore, step S31 specifically includes:

[0078] Acquire all first spaces where the smoke concentration value is greater than or equal to a preset value;

[0079] Based on the comparison between the smoke concentration value and the preset value, obtain the smoke concentration level of all first spaces whose smoke concentration value is greater than or equal to the preset value;

[0080] Based on the smoke concentration level, the power level and moving speed level of the blower structure in each first space are matched and obtained;

[0081] Based on the power level and moving speed level of the blower structure, and the preset value of the solenoid valve 12, the smoke inside the vehicle is discharged by operating the blower structure until the smoke concentration value in the entire first space is less than the set preset value, at which point the smoke discharge stops.

[0082] Continuing with the previous example, if the smoke concentration level detected in the first space of the driver's cab is level 3, then the smoke particle concentration in the first space is between 36 and 50 μg / m³. 3 If the smoke concentration is maintained for 10 seconds, then the power level of the blower structure obtained from the smoke concentration level is level 3, the movement level of the blower structure is level 1, and the preset value of the solenoid valve 12 is 30% opening. At this time, the movement speed of the blower structure is controlled by controlling the retractable structure 2; the exhaust speed (i.e., power level) of the blower structure is controlled by controlling the speed of the fan motor, thereby quickly expelling the harmful gas in the space.

[0083] Furthermore, based on the movement level of the blower structure, the blower structure reciprocates according to the movement level. When the smoke concentration is high, this method can expel harmful gases more quickly and reduce the additional harm of smoke.

[0084] In this implementation, the power level and moving speed level of the blower structure corresponding to the smoke level can be preset according to the volume of the vehicle interior space and the flow rate of the blower structure, thereby achieving the highest exhaust effect.

[0085] Furthermore, it also includes the following steps:

[0086] Obtain the vehicle's operating speed;

[0087] When the vehicle's operating speed is zero, proceed to step 31;

[0088] Specifically, when the vehicle's operating speed is zero, a detection step is also included; the detection step specifically includes: detecting whether the doors and windows are closed; if both the doors and windows are closed, then step 31 is executed; if either the door or the window is open, then the triggering control strategy is stopped.

[0089] When the vehicle's operating speed is greater than zero, proceed to step 32;

[0090] Step 32 specifically includes:

[0091] Obtain the target speed of the vehicle at that time;

[0092] Based on the comparison result between the target speed and the preset speed range, obtain the level adjustment value corresponding to the target speed;

[0093] Adjust the power level and moving speed level of the blower structure according to the adjustment value;

[0094] The exhaust of the blower structure is controlled according to the power level and moving speed level of the adjusted blower structure.

[0095] Specifically, when the vehicle's operating speed is greater than zero, the vehicle's current speed is obtained. By comparing the current speed with a preset speed range, the level adjustment value corresponding to the target speed is determined. Based on the level adjustment value, the power level and movement speed level of the blower structure are adjusted.

[0096] Continuing with the previous example, if the vehicle's speed is 50 km / h, then it falls within the speed range of 40-60 km / h, and the level adjustment value obtained is 1. This level adjustment value is then added to the power level and movement speed level of the blower structure, resulting in an adjusted power level of 4 and a movement level of 2 for the blower structure. By increasing the movement speed and exhaust speed of the blower structure, the removal of harmful gases from the vehicle is accelerated, preventing interference with the driver's visibility and ensuring driving safety.

[0097] Furthermore, adjusting the power level and moving speed level of the blower structure according to the level adjustment value specifically includes:

[0098] When the power level and movement level of the adjusted blower structure are greater than or equal to the level threshold, a warning message is triggered, and weather information outside the vehicle is obtained; the weather information includes at least wind speed and weather conditions.

[0099] Based on weather information, the preset value of the solenoid valve is adjusted; the preset value of the solenoid valve includes at least the preset opening value and the preset opening direction of the solenoid valve.

[0100] Continuing with the previous example, when the smoke concentration in the first space inside the vehicle is between 50 and 50 μg / m³... 3 When the smoke concentration level is at or above level 4, and is greater than or equal to the level threshold (e.g., level 4), an in-vehicle warning is triggered, indicating that there are too many harmful particles in the air inside the vehicle, which may endanger the safety of the occupants and even affect safe driving. At this time, a warning is issued to the occupants, and the opening value of the solenoid valve is adjusted, for example, from 30% to 60%; at the same time, the external circulation of the air conditioning system is switched off.

[0101] On the other hand, this application provides an in-vehicle smoke exhaust control system, including:

[0102] The partitioning module is configured to divide the vehicle interior space into multiple first spaces based on the vehicle type and interior space area; each first space contains at least one blower structure.

[0103] The acquisition module is configured to acquire the smoke concentration value inside each first space.

[0104] The central processing module is configured to compare the smoke concentration value of each first space with a preset value, and execute the corresponding control strategy based on the comparison result.

[0105] It is worth noting that although this system only discloses the partitioning module, the acquisition module, and the central processing module, it does not mean that this device is limited to the above-mentioned basic functional modules. The meaning of this invention is that, based on the above-mentioned basic functional modules, those skilled in the art can add one or more functional modules in combination with the prior art to form an infinite number of embodiments or technical solutions.
