[0055] Combine the following Figure 1 Embodiment 1 of the present application is described in detail.

[0056] Example 1

[0057] A smoke exhaust device in a vehicle, comprising: at least one exhaust structure 1 arranged in the vehicle; each exhaust structure 1 comprises: an exhaust duct 11 that can connect the space inside and outside the vehicle; wherein, a retractable structure 2 is provided at one end outlet of the exhaust duct 11 located in the vehicle, and an electromagnetic valve 12 with adjustable opening is provided at the other end outlet; wherein, a driving device connected to the retractable structure 2 is also provided inside the outlet of the exhaust duct 11 corresponding to the retractable structure 2; a blast structure 3 is provided at one end of the retractable structure 2 away from the driving device; and further comprising: a central control module electrically connected to the driving device, the blast structure 3 and the electromagnetic valve 12 respectively; the central control module is used to execute a corresponding control strategy according to the smoke concentration in the vehicle.

[0058] The solenoid valve 12 is provided with a mounting seat 4 for mounting the housing of the solenoid valve 12 at a position corresponding to the outer surface of the vehicle;

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

[0060] Specifically, the present application can efficiently and intelligently discharge harmful gases generated in the car by arranging multiple exhaust structures 1 in the car, thereby ensuring the air quality and environmental hygiene in the car space, and ensuring the user's driving experience and comfort during driving.

[0061] Furthermore, the telescopic structure 2 includes: a multi-stage telescopic rod 21 which is drive-connected to the driving device and is a hollow structure; the multi-stage telescopic rod 21 includes at least two first hollow rods 210 and second hollow rods 211 which are relatively slidably connected; 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 limitedly slidably connected to the exhaust duct 11, and the other end is limitedly slidably connected to one end of the second hollow rod 211; the other end of the second hollow rod 211 is connected to the blowing 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 push rod motor and is 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 push rod motor can extend out of the exhaust duct 11 and is connected to the multi-stage telescopic rod 21. The end of the output end of the linear push rod motor is fixed to the inner wall of the second hollow rod 211, and can drive the second hollow rod 211 and the first hollow rod 210 to perform linear motion, thereby driving the air blowing structure 3 to move.

[0063] Specifically, the multi-stage telescopic rod 21 designed in the present application can adjust the position of the blowing structure 3 according to the smoke concentration in the vehicle to achieve a fast and intelligent smoke exhaust function, and can 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 air blowing structure 3 includes: an air duct 31 connected to the second hollow rod 211, a turbine housing 32 connected to the air duct 31, a fan 34 arranged inside the turbine housing 32, and a fan motor 33 arranged 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 end 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; and the fan motor 33 is fixed to the inside of the turbine housing 32 through the fan motor housing.

[0065] Specifically, the present application drives the fan motor to drive the fan to rotate, thereby discharging harmful gases in the vehicle interior space through the air duct 31, the multi-stage telescopic rod and the air duct in sequence to the outside of the vehicle, thereby ensuring the air quality in the vehicle.

[0066] It can be understood that the in-vehicle smoke exhaust device and smoke exhaust method provided by the present application can be suitable for special environments. During the application process, there is no need to open the car windows. Through intelligent control, harmful gases in the car can be quickly discharged out of the car, thereby improving the user's driving experience and comfort as a whole.

[0067] In a second aspect, the present application provides a method for controlling smoke exhaust in a vehicle, comprising the following steps:

[0068] Step S1: Divide the interior space of the vehicle into a plurality of first spaces according to the vehicle type and the interior space area; wherein at least one exhaust structure 1 is provided in each first space;

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

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

[0071] Specifically, the present application can divide the interior space of the vehicle into multiple first spaces according to the area of ​​the interior space and vehicle model information, so that the exhaust structure can be arranged according to different vehicle models. Furthermore, it is convenient to accurately obtain the smoke concentration in different spatial areas in the vehicle. By detecting the smoke concentration in a single space and utilizing the exhaust structure 1, harmful gases in the space can be quickly and efficiently discharged.

[0072] For example, taking an MPV as an example, the main driver's cab and the co-driver's cab are combined into one space, and the passenger space of the back two rows is divided into two first spaces with the rear side of the single-row seats as the boundary; wherein, two smoke concentration sensors are arranged in the inner area of ​​each first space to collect the smoke concentration value in the space, so that the smoke concentration information of each space can be accurately obtained. Preferably, smoke concentration sensors are arranged at the top of each first space near the turbine housing and on the vehicle inner panel at the same height as the shoulder side of the passenger when the passenger is sitting upright.

[0073] Furthermore, by comparing the smoke concentration value in each first space with the set preset value, the smoke concentration level of each space is determined internally, and corresponding control strategies are adopted accordingly. While having high intelligence, it can quickly exhaust harmful gases, thereby improving the user's driving experience and comfort.

[0074] Furthermore, the smoke concentration value of each first space is compared with a preset value, and a corresponding control strategy is executed according to the comparison result, which specifically includes:

[0075] S30: acquiring in real time the maximum smoke density value among all the smoke density values ​​of the first space;

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

[0077] Furthermore, the step S31 specifically includes:

[0078] Acquire all first spaces whose smoke concentration values ​​are greater than or equal to a preset value;

[0079] According to the comparison result between the smoke density value and the preset value, the smoke density levels of all the first spaces whose smoke density values ​​are greater than or equal to the preset value are obtained;

[0080] According to the smoke concentration level, matching and obtaining the power level of the air blowing structure and the moving speed level of the air blowing structure in each first space;

[0081] According to the power level and moving speed grade of the blowing structure, based on the preset value of the solenoid valve 12, the smoke in the vehicle is exhausted by running the blowing structure until the smoke concentration value in the entire first space is less than the preset value, and then the smoke exhaust is stopped.

[0082] Continuing with the previous example, if the smoke concentration level detected in the first space of the cab is level 3, the smoke particle concentration in the first space is between 36 and 50 μg / m 3 And the smoke concentration is maintained for 10 seconds, then the power level of the blowing structure obtained by the smoke concentration level is level 3, the movement level of the blowing structure is level 1, and the preset value of the solenoid valve 12 is an opening of 30%. At this time, the movement speed of the blowing structure is controlled by controlling the retractable structure 2; the exhaust speed (i.e., the power level) of the blowing structure is controlled by controlling the speed of the fan motor, so that the harmful gases in the space can be quickly discharged.

[0083] Furthermore, according to the movement level of the blowing structure, the blowing structure is made to make reciprocating motion according to the movement level. When the smoke concentration is at a high level, this method can discharge harmful gases faster and reduce the additional harm of smoke.

[0084] In this embodiment, the power level and moving speed level of the air blowing structure corresponding to the smoke level can be pre-set according to the volume of the space inside the vehicle and the flow rate of the air blowing structure, so as to achieve the highest exhaust effect.

[0085] Furthermore, the method further comprises the following steps:

[0086] Get the running speed of the vehicle;

[0087] When the running speed of the vehicle is zero, step 31 is executed;

[0088] Specifically, when the running speed of the vehicle is zero, it also includes a detection step; the detection step specifically includes: detecting whether the doors and windows are closed; if the doors and windows are both closed, executing step 31; if any one of the doors and / or windows is open, then stopping the triggering control strategy.

[0089] When the running speed of the vehicle is greater than zero, step 32 is executed;

[0090] The step 32 specifically includes:

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

[0092] According to the comparison result between the target speed and the preset speed interval, obtaining a level adjustment value corresponding to the target speed;

[0093] According to the level adjustment value, the power level of the blast structure and the moving speed level of the blast structure are adjusted;

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

[0095] Specifically, when the vehicle's running speed is greater than zero, the vehicle's current driving speed is obtained, and the level adjustment value corresponding to the target speed is determined by comparing the driving speed with the preset speed range; according to the level adjustment value, the power level and moving speed level of the blowing structure are adjusted.

[0096] Continuing with the previous example, when the vehicle's driving speed is 50km / h, it falls within the speed range of 40-60km / h, and the obtained level adjustment value is 1; then, the level adjustment value is added to the power level and moving speed level of the blower structure respectively, and the power level of the adjusted blower structure is 4, and the moving level of the blower structure is 2. By increasing the moving speed and exhaust speed of the blower structure, the exhaust of harmful gases in the car is accelerated to avoid interfering with the driver's driving vision and affecting driving safety.

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

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

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

[0100] Continuing with the previous example, when the smoke concentration in the first space of the vehicle is between 50 and 50 μg / m 3 During the interval, if the smoke concentration level is at level 4 and is greater than or equal to the level threshold (e.g., level 4), a warning prompt is triggered in the car, indicating that there are too many harmful particles in the air in the car, which may cause the safety of the occupants in the car and even affect safe driving. At this time, a warning is given to the users in the car, and the opening value of the solenoid valve is adjusted, such as adjusting the opening of the solenoid valve from 30% to 60%; at the same time, the external circulation of the air-conditioning system is turned on.

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

[0105] It is worth noting that although the present system only discloses a division module, an acquisition module and a central processing module, it does not mean that the present device is limited to the above-mentioned basic functional modules; what the present invention wants to express is that, based on the above-mentioned basic functional modules, those skilled in the art can arbitrarily add one or more functional modules in combination with the prior art to form an infinite number of embodiments or technical solutions, that is to say, the present system is open rather than closed, and because the present embodiment only discloses individual basic functional modules, it cannot be considered that the scope of protection of the claims of the present invention is limited to the above-mentioned disclosed basic functional modules.
