[0042] The exemplary embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be fully conveyed to those skilled in the art.
[0043] In the first aspect of the embodiments of the present application, a vehicle with a fire prevention system is provided, as Figure 1 shown, the vehicle includes: an airbag controller 1 and at least one airbag, and the airbag controller 1 and the at least one airbag are connected by a signal line 2;
[0044] at least one fire extinguishing device 3, and the at least one fire extinguishing device 3 is connected to the airbag controller 1 by a signal line 2;
[0045] when the airbag controller 1 sends an airbag activation signal to the at least one airbag, it sends a fire extinguishing device activation signal to the at least one fire extinguishing device 3;
[0046] the at least one airbag inflates in response to the airbag activation signal;
[0047] The at least one fire extinguishing device 3 releases a fire extinguishing agent in response to the fire extinguishing device activation signal.
[0048] Specifically, the vehicle with a fire prevention system provided in this embodiment includes, as Figure 1 shown, an airbag controller 1 and at least one airbag. Among them, the airbag controller 1 and the at least one airbag are connected by a signal line 2. The vehicle further includes at least one fire extinguishing device 3, where the airbag controller 1 and the at least one fire extinguishing device 3 are connected by the signal line 2. When the airbag controller 1 sends an airbag activation signal to the at least one airbag, it simultaneously sends a fire extinguishing device activation signal to the at least one fire extinguishing device 3. After receiving the airbag activation signal, the at least one airbag inflates by detonating in response to the airbag activation signal. After receiving the fire extinguishing device activation signal, the at least one fire extinguishing device 3 releases a fire extinguishing agent in response to the fire extinguishing device activation signal.
[0049] In this application, the airbag controller 1 is electrically connected to the airbag and the fire extinguishing device 3 respectively. By controlling the detonation of the airbag by the airbag controller 1 and simultaneously controlling the fire extinguishing device 3 to release a fire extinguishing agent, it is possible to effectively avoid problems such as fires and casualties caused by the inability of the fire extinguishing device 3 to start normally due to vehicle deformation after a vehicle collision.
[0050] The vehicle with a fire prevention system provided in this embodiment includes an airbag controller 1 and at least one airbag, which are connected by a signal line 2. At the same time, it further includes at least one fire extinguishing device 3, and the fire extinguishing device 3 is also connected to the airbag controller 1 by the signal line 2. In this embodiment, the airbag controller 1 can not only send an airbag activation signal to the at least one airbag, but also send a fire extinguishing device activation signal to the at least one fire extinguishing device 3. This shows that the airbag controller 1 can perform multiple key tasks at the same time, including inflating the airbag and activating the fire extinguishing device 3. The airbag controller 1 coordinates the activation of the airbag and the fire extinguishing device 3 to ensure their effective cooperation in a collision accident. The inflation of the airbag can form a protective barrier to reduce the risk of injury to the occupants, while the release of the fire extinguishing agent by the fire extinguishing device 3 can prevent a fire accident caused by the collision of the engine 5. The vehicle with a fire prevention system provided in the embodiment of this application has unique fire prevention characteristics and can release a fire extinguishing agent before the vehicle is damaged by a collision. This characteristic is very crucial for the early control of fires and can reduce the scale and damage of fires. The airbag controller 1 can precisely control the inflation of the airbag and the release of the fire extinguishing agent by the fire extinguishing device 3 to meet the requirements of a specific collision accident and ensure sufficient support and fire extinguishing effect.
[0051] In a preferred embodiment of this application, the vehicle further includes: at least one collision sensor, and the at least one collision sensor is connected to the airbag controller 1 by a signal line 2;
[0052] The at least one collision sensor is configured to collect collision parameter values of the vehicle when a vehicle collision occurs, and send the collision parameter values to the airbag controller 1;
[0053] The airbag controller 1 is configured to generate airbag activation information based on the collision parameter values and an activation critical point, and convert the airbag activation information into the airbag activation signal and the fire extinguishing device activation signal.
[0054] Specifically, in this embodiment, at least one collision sensor is installed at key positions of the vehicle to ensure that collision parameter values can be quickly and accurately captured when a vehicle collision accident occurs. In practical applications, these collision sensors can be installed at the front, side, rear of the vehicle, and around the occupant cockpit to comprehensively monitor potential collisions.
[0055] The at least one collision sensor is connected to the airbag controller 1 through a signal line 2. After a vehicle collision accident occurs, the collision sensor can send the collected collision parameter values to the airbag controller 1. An intelligent algorithm can be configured in the airbag controller 1 to accurately calculate the collision parameter values of the collision sensor, so as to determine the severity, direction, speed, etc. of the collision, enabling the airbag controller 1 to better adapt to different types of collision accidents.
[0056] The airbag controller 1 not only receives the collision parameter values of the collision sensor, but also needs to generate airbag activation information based on a predetermined activation critical point, and convert the airbag activation information into an airbag activation signal and a fire extinguishing device activation signal. The airbag controller 1 sends the airbag activation signal and the fire extinguishing device activation signal to at least one airbag and at least one fire extinguishing device 3 respectively. After receiving the airbag activation signal, the at least one airbag inflates by detonating in response to the airbag activation signal. After receiving the fire extinguishing device activation signal, the at least one fire extinguishing device 3 releases a fire extinguishing agent in response to the fire extinguishing device activation signal.
[0057] In this embodiment, the detonation critical point may be a preset collision acceleration. Therefore, the collision parameter value corresponding to the detonation critical point is the collision acceleration. When the collision acceleration is greater than or equal to the preset collision acceleration, the airbag controller 1 will generate airbag detonation information and convert the airbag detonation information into an airbag activation signal and a fire extinguishing device activation signal. The airbag controller 1 will send the airbag activation signal and the fire extinguishing device activation signal to at least one airbag and at least one fire extinguishing device 3 respectively. After receiving the airbag activation signal, at least one airbag will inflate by detonating in response to the airbag activation signal. After receiving the fire extinguishing device activation signal, at least one fire extinguishing device 3 will release the fire extinguishing agent in response to the fire extinguishing device activation signal. Thus, after a vehicle collision, it is possible to both activate the airbag to protect the safety of the vehicle occupants and at the same time activate the fire extinguishing device 3 to reduce the risk of fire and protect the vehicle occupants from the threat of fire. In this embodiment, after a vehicle collision accident, the airbag and the fire extinguishing device 3 can be activated simultaneously, so that the fire extinguishing agent can be released before the fire extinguishing device 3 is deformed by the collision, effectively avoiding the occurrence of fire.
[0058] In a preferred embodiment of the present application, the vehicle further includes: a vehicle controller and at least one collision sensor; the vehicle controller is connected to the airbag controller 1 through a signal line 2; the at least one collision sensor is connected to the vehicle controller through the signal line 2;
[0059] The at least one collision sensor is configured to collect the collision parameter value of the vehicle when the vehicle collides and send the collision parameter value to the vehicle controller;
[0060] The vehicle controller is configured to generate airbag detonation information according to the collision parameter value and the detonation critical point and send the airbag detonation information to the airbag controller 1;
[0061] The airbag controller 1 is configured to convert the airbag detonation information into the airbag activation signal and the fire extinguishing device activation signal.
[0062] Specifically, in this embodiment, the vehicle further includes a vehicle controller, and at least one collision sensor and an airbag controller 1 that are respectively connected to the vehicle controller through signal line 2. Among them, at least one collision sensor is installed at key positions of the vehicle. For example, it can be installed at the front, side, rear of the vehicle and around the passenger cabin to comprehensively monitor potential collisions. At least one collision sensor is connected to the vehicle controller through signal line 2. After a collision accident occurs to the vehicle, the collision sensor can send the collected collision parameter values to the vehicle controller. An intelligent algorithm can be configured in the vehicle controller, which can accurately calculate the collision parameter values of the collision sensor, so as to determine the severity, direction, speed, etc. of the collision, enabling the vehicle controller to better adapt to different types of collision accidents.
[0063] The vehicle controller is not only responsible for collecting the collision parameter values, but also needs to generate airbag activation information according to a predetermined activation critical point. In practical applications, the airbag activation information may include when, where, and how to activate the airbag and the fire extinguishing device to ensure that the occupants are properly protected in a collision accident. The vehicle controller then transmits the airbag activation information to the airbag controller 1 to control the activation of the airbag and the fire extinguishing device 3.
[0064] After receiving the airbag activation information, the airbag controller 1 converts the airbag activation information into an airbag activation signal and a fire extinguishing device activation signal. The airbag controller 1 sends the airbag activation signal and the fire extinguishing device activation signal to at least one airbag and at least one fire extinguishing device 3 respectively. After receiving the airbag activation signal, at least one airbag inflates by detonating in response to the airbag activation signal. After receiving the fire extinguishing device activation signal, at least one fire extinguishing device 3 releases the fire extinguishing agent in response to the fire extinguishing device activation signal. Thus, after a collision occurs to the vehicle, it can not only activate the airbag to protect the safety of the occupants in the vehicle, but also activate the fire extinguishing device 3 to reduce the risk of fire and protect the occupants in the vehicle from the threat of fire.
[0065] This embodiment provides comprehensive safety through the coordination of the vehicle controller, the accurate data collection of the collision sensor, and the efficient execution of the airbag controller 1, ensuring the maximum protection of the occupants in a collision accident.
[0066] In a preferred embodiment of the present application, the at least one fire extinguishing device 3 is disposed under the floor 4 of the vehicle's cockpit, and the nozzle of the fire extinguishing device 3 faces the engine 5 of the vehicle.
[0067] In this embodiment, continue to refer to Figure 1, at least one fire extinguishing device 3 is arranged below the cockpit floor 4 of the vehicle, and the nozzles of the fire extinguishing device 3 all face the vehicle engine 5, so that after the vehicle collides and the fire extinguishing device 3 is activated, the fire extinguishing agent can be sprayed onto the engine 5 to prevent the engine 5 from burning and causing a fire.
[0068] In the embodiment of the present application, in order to avoid a fire caused by the failure of the fire extinguishing device configured on the vehicle to start normally due to severe damage to the vehicle after a vehicle collision accident, which may cause secondary harm to the vehicle occupants. In the present application, after a vehicle collision accident occurs, first, at least one collision sensor installed on the vehicle collects the collision parameter values of the vehicle, and the collision sensor sends the collision parameter values to the airbag controller 1 or to the vehicle controller. When the collision sensor sends the collision parameter values to the airbag controller 1, the airbag controller 1 generates airbag detonation information based on the collision parameter values and a preset detonation critical point. Among them, in the present application, the collision parameter value is the collision acceleration when the vehicle collides, and the detonation critical point is a preset collision acceleration. Therefore, when the collision acceleration is greater than or equal to the preset collision acceleration, the airbag controller 1 generates airbag detonation information, and the airbag controller 1 converts the airbag detonation information into an airbag start signal and a fire extinguishing device start signal, and simultaneously sends the airbag start signal and the fire extinguishing device start signal to at least one airbag and at least one fire extinguishing device 3 respectively, so as to control the simultaneous start of at least one airbag and at least one fire extinguishing device 3, and provide double protection for the vehicle occupants through the airbag and the fire extinguishing device. That is, after a vehicle collision accident occurs, the first protection for the vehicle occupants is provided by activating the airbag. At the same time, the occurrence of a fire is prevented by activating the fire extinguishing device 3, so as to provide the second protection for the vehicle occupants. By controlling the simultaneous start of the airbag and the fire extinguishing device 3 at the moment of vehicle collision, the problem that the fire extinguishing device configured on the vehicle fails to start normally due to a fault and causes a fire due to severe damage to the vehicle can be effectively avoided.
[0069] In this application, when the collision parameter value is sent to the vehicle control unit by the collision sensor, the vehicle control unit generates the airbag detonation information based on the collision parameter value and the preset detonation critical point. Herein, in this application, the collision parameter value is the collision acceleration when the vehicle collides, and the detonation critical point is the preset collision acceleration. Therefore, when the collision acceleration is greater than or equal to the preset collision acceleration, the vehicle control unit generates the airbag detonation information, and the vehicle control unit sends the airbag detonation information to the airbag controller 1. The airbag controller 1 converts the airbag detonation information into an airbag activation signal and a fire extinguishing device activation signal, and simultaneously sends the airbag activation signal and the fire extinguishing device activation signal to at least one airbag and at least one fire extinguishing device 3 respectively, so as to control the simultaneous activation of at least one airbag and at least one fire extinguishing device 3, and double-protect the vehicle occupants through the airbag and the fire extinguishing device 3. That is, after a vehicle collision accident occurs, the vehicle occupants are protected for the first time by activating the airbag. At the same time, the occurrence of a fire is prevented by activating the fire extinguishing device 3, so as to provide the second protection for the vehicle occupants. By controlling the simultaneous activation of the airbag and the fire extinguishing device 3 at the moment of vehicle collision, the problem that the fire extinguishing device 3 configured on the vehicle cannot be normally activated due to a fault and thus causes a fire due to severe vehicle damage can be effectively avoided.
[0070] An embodiment of this application provides a vehicle with a fire prevention system. The vehicle includes: an airbag controller and at least one airbag, and the airbag controller and the at least one airbag are connected by a signal line; at least one fire extinguishing device, and the at least one fire extinguishing device is connected to the airbag controller by a signal line; the airbag controller sends a fire extinguishing device activation signal to the at least one fire extinguishing device while sending an airbag activation signal to the at least one airbag; the at least one airbag inflates by detonating in response to the airbag activation signal; the at least one fire extinguishing device releases a fire extinguishing agent in response to the fire extinguishing device activation signal. In this application, the airbag controller is electrically connected to the airbag and the fire extinguishing device respectively. By controlling the detonation of the airbag by the airbag controller and simultaneously controlling the fire extinguishing device to release the fire extinguishing agent, the problems of fire caused by the inability of the fire extinguishing device to be normally activated due to vehicle deformation and casualties can be effectively avoided after the vehicle collides.
[0071] Based on the same inventive concept, in the second aspect of the embodiment of this application, a fire prevention method is provided, as Figure 2 shown. The method includes:
[0072] Step S101, when the vehicle collides, send an airbag activation signal to at least one airbag and send a fire extinguishing device activation signal to at least one fire extinguishing device at the same time;
[0073] Step S102, based on the airbag activation signal, control the at least one airbag to inflate by detonating;
[0074] Step S103, based on the fire extinguishing device start signal, control the at least one fire extinguishing device to release the fire extinguishing agent.
[0075] Specifically, in the embodiment of the present application, after a vehicle collision accident occurs, at least one collision sensor installed on the vehicle will collect the collision parameter values when the vehicle collides, and send the collected collision parameter values to the airbag controller of the vehicle. After obtaining the collision parameter values, the airbag controller of the vehicle generates airbag detonation information based on a predetermined detonation critical point, converts the airbag detonation information into an airbag start signal and a fire extinguishing device start signal, and sends the airbag start signal and the fire extinguishing device start signal to at least one airbag and at least one fire extinguishing device respectively. After receiving the airbag start signal, at least one airbag detonates and inflates, and the inflated airbag forms a protective barrier in the collision accident to reduce the risk of injury to the occupants. In addition, the airbag controller can precisely control the inflation process of the airbag to ensure sufficient support at the moment of collision while avoiding over-inflation. At the same time, after receiving the fire extinguishing device start signal, at least one fire extinguishing device releases the fire extinguishing agent, and the released fire extinguishing agent can inhibit the spread of the fire and prevent more serious damage caused by the fire, thereby effectively avoiding the rapid development of the fire after the collision accident and avoiding secondary injuries to the vehicle occupants.
[0076] Exemplarily, in the embodiment of the present application, the fire extinguishing device adopted after vehicle collision has a key technical effect, that is, releasing the fire extinguishing agent before the fire extinguishing device is damaged to prevent the occurrence of fire in advance. Specifically, when a vehicle collision accident occurs, the collision sensor immediately collects the collision parameter values and sends them to the airbag controller. The airbag controller uses these parameters to judge the severity of the collision and generates airbag detonation information according to a predetermined detonation critical point. However, at the same time, it can also use these parameters to predict the potential risk of fire. If the collision parameters indicate that a fire may occur, the airbag controller can trigger the fire extinguishing device in advance to release the fire extinguishing agent to suppress the potential fire source. In the present application, by releasing the fire extinguishing agent after the collision accident and before the fire extinguishing device is deformed and fails, the occurrence of fire can be effectively avoided and the risk of fire can be reduced. This can prevent the rapid spread of the fire because the fire extinguishing device has released the fire extinguishing agent before the vehicle is damaged, thereby ensuring the safety of the vehicle occupants.
[0077] In a preferred embodiment of the present application, before sending the airbag start signal to the at least one airbag and sending the fire extinguishing device start signal to the at least one fire extinguishing device, it further includes:
[0078] Obtain the collision parameter values of the vehicle collected by at least one collision sensor;
[0079] Generate airbag deployment information based on the collision parameter value and the detonation critical point, and convert the airbag deployment information into the airbag activation signal and the fire extinguishing device activation signal.
[0080] In the embodiment of the present application, before sending the airbag activation signal to at least one airbag and sending the fire extinguishing device activation signal to at least one fire extinguishing device, the following steps are further included:
[0081] Collect the collision parameter value through at least one collision sensor installed on the vehicle. Among them, at least one collision sensor can be installed at the front, side, rear of the vehicle and around the passenger cabin to comprehensively monitor potential collisions, and quickly obtain the collision parameter value after a vehicle collision accident occurs.
[0082] Further, by comparing the obtained collision parameter value with the pre-set detonation critical point in advance, airbag deployment information can be generated, and after generating the airbag deployment information, the airbag deployment information is converted into an airbag activation signal capable of controlling the airbag deployment and a fire extinguishing device activation signal capable of controlling the release of the fire extinguishing agent by the fire extinguishing device.
[0083] Exemplarily, in the embodiments of the present application, the vehicle is equipped with at least one collision sensor, which are distributed around the front, side, rear of the vehicle and the occupant cabin. The installation of these collision sensors ensures comprehensive monitoring of potential collision accidents. When a collision accident occurs to the vehicle, these collision sensors immediately collect collision parameter values, which include the intensity, direction, speed, etc. of the collision. In the present application, the collision acceleration is taken as the collision parameter value for illustration. After the collision acceleration is collected by the collision sensor, it will then be compared with a preset detonation critical point, i.e., the preset collision acceleration. These preset thresholds are determined in advance to trigger corresponding safety measures according to the severity of the collision. If the comparison result indicates that the collision reaches or exceeds the set detonation critical point, i.e., the collision acceleration is greater than or equal to the preset collision acceleration, an airbag detonation information is generated. This information reflects the urgency and severity of the collision event and determines when and how to trigger the airbag and the fire extinguishing device. Further, the generated airbag detonation information will subsequently be converted into an airbag activation signal and a fire extinguishing device activation signal. The airbag activation signal is used to control the detonation and inflation process of at least one airbag, while the fire extinguishing device activation signal is used to control the release of the fire extinguishing agent of at least one fire extinguishing device. Once the activation signals of the airbag and the fire extinguishing device are generated, the system can perform these two tasks simultaneously. The airbag inflates to form a protective barrier to reduce the impact of the collision event on the occupants, while the fire extinguishing device releases the fire extinguishing agent to prevent the spread of the fire source. The present application collects the collision parameter values quickly, compares them with the detonation critical point, generates the airbag detonation information, and finally triggers the airbag and the fire extinguishing device, thereby minimizing the risks brought by the collision accident and preventing the occurrence of fire at the same time. This helps to ensure that the vehicle occupants will not be subject to secondary injuries.
[0084] In a preferred embodiment of the present application, before sending the airbag activation signal to the at least one airbag and sending the fire extinguishing device activation signal to the at least one fire extinguishing device, it further includes:
[0085] Obtaining the collision parameter values of the vehicle collected by at least one collision sensor through the vehicle controller;
[0086] Obtaining the airbag detonation information generated by the vehicle controller based on the collision parameter values and the detonation critical point;
[0087] Converting the airbag detonation information into the airbag activation signal and the fire extinguishing device activation signal.
[0088] In this embodiment, the collision parameter values are collected by at least one collision sensor installed on the vehicle. Among them, at least one collision sensor can be installed around the front, side, rear of the vehicle and the member cabin to comprehensively monitor potential collisions and quickly obtain the collision parameter values after a collision accident occurs to the vehicle.
[0089] Further, at least one collision sensor sends the obtained collision parameter value to the vehicle controller, and the vehicle controller compares the obtained collision parameter value with a preset detonation critical point, so as to generate airbag detonation information. After generating the airbag detonation information, the airbag detonation information is converted into an airbag activation signal capable of controlling the airbag detonation and a fire extinguishing device activation signal capable of controlling the release of the fire extinguishing agent by the fire extinguishing device.
[0090] In a preferred embodiment of the present application, the collision parameter value is the collision acceleration, and the detonation critical point is the preset collision acceleration; generating the airbag detonation information based on the collision parameter value and the detonation critical point includes:
[0091] When the collision acceleration is greater than or equal to the preset collision acceleration, the airbag detonation information is generated.
[0092] In this embodiment, the severity of the collision accident is evaluated by the collision parameter value. Among them, the collision acceleration is used as an important index for evaluating the severity of the collision accident, and is compared with the preset detonation critical point, that is, the collision acceleration, so as to evaluate the severity of this collision accident.
[0093] Further, the obtained collision acceleration is compared with the preset collision acceleration. The preset collision acceleration is a threshold value, which represents the severity level of the collision that requires emergency measures. When the collision acceleration is greater than or equal to the preset collision acceleration, it indicates that the collision accident at this time is relatively serious, and corresponding protective measures need to be taken immediately to protect the lives of the vehicle occupants, such as: activating the airbag and / or activating the fire extinguishing device; when the collision acceleration is less than the preset collision acceleration, it indicates that the collision accident at this time is a minor collision accident, and the vehicle occupants will not be injured, so there is no need to take corresponding measures to protect the lives of the vehicle occupants.
[0094] Further, when the collision acceleration is greater than or equal to the preset collision acceleration, the airbag detonation information is generated.
[0095] Exemplarily, referring to Figure 3 a schematic diagram of the control logic for airbag detonation and fire extinguishing device activation shown, after a vehicle collision accident, first collect the collision parameter value of the vehicle through the collision acceleration installed on the vehicle. In the embodiment of the present application, the collision parameter value is the collision acceleration;
[0096] Further, the collision parameter value, i.e., the collision acceleration, is sent to the airbag controller by the collision sensor, and the airbag controller compares the collision acceleration with the detonation critical point, i.e., the preset collision acceleration. If the collision acceleration is greater than or equal to the preset collision acceleration, the conditions for activating the airbag and the fire extinguishing device are met. Then, the airbag controller generates the airbag detonation information and converts the airbag detonation information into an airbag activation signal and a fire extinguishing device activation signal. At the same time, the airbag activation signal is sent to at least one airbag, and the fire extinguishing device activation signal is sent to at least one fire extinguishing device. After receiving the airbag activation signal, at least one airbag detonates and inflates; after receiving the fire extinguishing device activation signal, at least one fire extinguishing device releases the fire extinguishing agent to protect the driver and passengers. If the collision acceleration is less than the preset collision acceleration, the airbag and the fire extinguishing device are not activated. It should be noted that in this embodiment, when the fire extinguishing device releases the fire extinguishing agent, it releases the fire extinguishing agent towards the vehicle engine to prevent the vehicle engine from catching fire and burning.
[0097] An embodiment of the present application provides a fire prevention method, which includes: when a vehicle collides, while sending an airbag activation signal to at least one airbag, sending a fire extinguishing device activation signal to at least one fire extinguishing device; controlling the at least one airbag to detonate and inflate based on the airbag activation signal; and controlling the at least one fire extinguishing device to release the fire extinguishing agent based on the fire extinguishing device activation signal. The present application can, after a vehicle collision accident, control the airbag to detonate and at the same time control the fire extinguishing device to release the fire extinguishing agent through the airbag controller, so as to effectively avoid the problems of fire caused by the inability of the fire extinguishing device to start normally due to vehicle deformation and casualties after the vehicle collides.
