Description

Technical Field

[0001] The invention relates to the technical field of vehicle safety, and in particular to a vehicle body cooling and spontaneous combustion prevention system. Background Art

[0002] Vehicles exposed to the sun may catch fire due to high temperatures, especially in the summer. With the increase in hot weather, the temperature inside the vehicle may rise rapidly without proper cooling measures, greatly increasing the risk of spontaneous combustion.

[0003] Therefore, it is necessary to be able to take timely measures in the early stage of temperature rise to reduce the risk of fire. At present, there are early warnings for spontaneous combustion of the vehicle body by monitoring the temperature inside the vehicle body. Although it has been partially automated, human intervention is still required after obtaining the monitoring results, and manual operation is required to take fire extinguishing measures; there are also methods to use smoke monitoring to judge the fire and then take measures to extinguish the fire, but in some cases, such as smoking in the car, it is easy to misjudge, resulting in the fire extinguishing equipment being mistakenly activated. At the same time, the existing cooling and spontaneous combustion prevention system often cannot accurately identify the location of the fire source and achieve fixed-point fire extinguishing, resulting in low fire extinguishing efficiency, which will cause waste of resources and damage to non-fire areas.

[0004] Therefore, an automated and intelligent temperature reduction and spontaneous combustion prevention warning system is needed that can respond quickly and effectively in the early stages of a fire and improve response capabilities. Summary of the invention

[0030] Figure 1 Schematic diagram of various modules of a vehicle body cooling and spontaneous combustion prevention system in an embodiment. DETAILED DESCRIPTION

[0031] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] This embodiment provides a vehicle body cooling and spontaneous combustion prevention system. Figure 1 , including a vehicle body provided with a skylight, wherein the vehicle body is provided with a control module, a monitoring module electrically connected to the control module, a power module, a communication module, a working indicator light, a positioning module, an alarm module and a relay.

[0034] The power module in this embodiment is an independent power module other than the vehicle's working power supply.

[0035] The relay is electrically connected to a temperature reduction module and a fire extinguishing module.

[0036] The cooling module includes a combined ventilation module. In the present embodiment, the combined ventilation module is an integrated component including a skylight assembly and an exhaust assembly. The skylight assembly includes a push rod type transmission assembly. The push rod type transmission assembly includes a driving motor electrically connected to a relay, the driving motor is connected to a reduction gear bearing, the reduction gear is connected to a screw rod, a nut on the screw rod connected to its stud is connected to one end of the push rod, and the other end of the push rod is connected to the skylight. The exhaust assembly includes an exhaust fan, and preferably a plurality of exhaust fans. In the present embodiment, a plurality of exhaust fans are distributed in rows. The exhaust fan includes a motor electrically connected to a relay, fan blades connected to the motor, and an air outlet duct, all of which are arranged on the side of the skylight frame, and an air outlet of the air outlet duct is arranged vertically on the side facing outward.

[0037] The fire extinguishing module includes several fire extinguisher terminals, all of which are electrically connected to the relay. The several fire extinguisher terminals can be respectively arranged at the middle position of the compartment in the vehicle body, the power module position, the vehicle working power position, the fuel tank position, the engine position and the rear tire position. The starting device of each fire extinguisher terminal is connected to an electronic pin, which is electrically connected to the relay.

[0038] The monitoring module includes a temperature sensor and several smoke sensors. The temperature sensor is arranged inside the vehicle body. The several smoke sensors can be arranged respectively at the middle position of the vehicle compartment, the power module position, the vehicle working power position, the fuel tank position, the engine position and the rear tire position.

[0039] The system of the present invention is applicable to both fuel vehicles and non-fuel vehicles. The above-mentioned fire extinguishing and smoke monitoring positions can be adaptively selected according to the vehicle type. For example, if it is a non-fuel vehicle, the fire extinguisher terminal and smoke sensor corresponding to the above-mentioned fuel tank position and engine position are not included.

[0040] The monitoring module collects the temperature data inside the vehicle body and the smoke concentration data at different positions in real time. The positioning module collects the real-time position data of the vehicle body and transmits the collected real-time position data, temperature data and smoke concentration data to the control module. The control module sends corresponding instructions to the relevant modules to execute processing actions based on the received data. The specific response mode is set as follows:

[0041] If the temperature data value reaches the set temperature threshold and the smoke concentration data values ​​at different locations do not reach the set smoke concentration threshold, the control module sends instructions to the relay and alarm module, the alarm horn sounds, the alarm indicator light flashes, the relay sends a signal to the cooling module, the push rod transmission assembly receives the signal, opens the sunroof, and at the same time the exhaust fan receives the signal and starts working until the temperature data value inside the vehicle body drops below the temperature threshold.

[0042] If the temperature data value reaches the set temperature threshold, and the smoke concentration data value at more than one location reaches the set smoke concentration threshold, the control module sends instructions to the relay, alarm module and communication module, the alarm horn sounds, the alarm indicator light flashes, the relay sends a signal to the cooling module and the fire extinguishing module, the push rod transmission assembly works, the skylight opens, and the exhaust fan starts working at the same time. After receiving the signal, the electronic pin opens the fire extinguisher terminal at the corresponding position and starts the fixed-point fire extinguishing work. The communication module sends the real-time position of the vehicle and the alarm signal to the fire center.

[0043] Specifically, in the present invention, the control module is the core of the entire vehicle cooling and self-ignition prevention system, responsible for receiving data from the monitoring module, analyzing and judging according to the preset logic, and sending a control signal to the relay to start the corresponding cooling and fire extinguishing actions when an abnormal situation is detected; at the same time, the control module is electrically connected to the power module, communication module, working indicator light, positioning module and alarm module for the exchange and transmission of data signals to coordinate and control each module in a unified manner. In this embodiment, the control module is specifically an MCU microcontroller.

[0044] The monitoring module is used to collect temperature data inside the vehicle body and smoke concentration data at different positions in real time. The monitoring module includes a temperature sensor and a plurality of smoke sensors. The temperature sensor is arranged inside the vehicle body. Furthermore, the temperature sensor is arranged at the top position inside the vehicle body, and is spaced a certain distance from the skylight, so that the collected temperature data can more accurately reflect the overall temperature condition inside the vehicle. The temperature sensor monitors the temperature inside the vehicle body in real time, and converts the temperature data into an electrical signal and transmits it to the control module. The temperature sensor used in the present invention is a thermistor temperature sensor, which has a fast response speed.

[0045] Several smoke sensors are respectively arranged at the middle position of the vehicle body, the power module position, the vehicle working power position, the fuel tank position, the engine position and the rear tire position (non-fuel vehicles do not include the fuel tank position and the engine position). These positions are all areas with high fire risks. By arranging smoke sensors at different positions, the impact of air flow on smoke detection can be reduced, ensuring that all areas are monitored, improving the accuracy of fire judgment, and timely discovering potential fire hazards. The smoke sensor used in the present invention is a photoelectric smoke sensor, which is more sensitive to fire sources.

[0046] The cooling module is used to take measures quickly when the temperature inside the vehicle body is monitored to be too high and the temperature data value reaches the set temperature threshold, so as to prevent the temperature from rising further and reduce the risk of spontaneous combustion of the vehicle body. The temperature threshold in this embodiment is set to 40°C, or higher. The cooling module includes a combined ventilation module, which is an integrated component including a skylight assembly and an exhaust assembly. The skylight assembly includes a push rod transmission assembly, which includes a drive motor electrically connected to a relay, a drive motor connected to a reduction gear bearing, a reduction gear connected to a screw rod, a nut connected to its stud on the screw rod is connected to one end of the push rod, and the other end of the push rod is connected to the skylight. The drive motor can select a 12V DC permanent magnet motor. The exhaust assembly includes exhaust fans distributed in rows, and the exhaust fan includes a motor electrically connected to a relay, a fan blade connected to the motor, and an air outlet duct, all of which are arranged on the side of the skylight frame, and the air outlet of the air outlet duct is arranged vertically to the side facing outward.

[0047] When the opening signal transmitted by the relay is received, the push rod transmission assembly pushes the sunroof open. Specifically, the drive motor is decelerated by the reduction gear, which drives the relative movement of the screw and the nut. The rotational motion of the motor is converted into linear motion, completing the push rod action to open the sunroof, thereby increasing the air circulation inside and outside the vehicle body, expelling the hot air in the vehicle body, and lowering the temperature inside the vehicle body. At the same time, the exhaust fan starts to work, and the motor drives the fan blades to rotate, generating suction to draw the hot air in the car into the exhaust fan. Subsequently, the inhaled hot air is discharged out of the car through the air outlet duct, thereby lowering the temperature inside the car.

[0048] In the cooling-only mode, the trigger judgment data is preferably provided by a rain sensor arranged at the sunroof position. When the rain sensor does not detect rain, the instructions of the push-rod transmission assembly to push the sunroof open and the exhaust fan to start working are executed normally. When the rain sensor detects rain, the instruction of the push-rod transmission assembly to push the sunroof open is executed only when the internal temperature of the vehicle body reaches the set limit threshold (the limit threshold is higher than the temperature threshold mentioned above, for example, reaching above 65°C). Otherwise, only the instruction of the exhaust fan to start working is executed. Since the exhaust fans are arranged in rows on both sides of the sunroof frame, they are small in size but powerful and have a high flow rate. In addition, a check valve can be provided in the air outlet duct, which will not be affected by rain.

[0049] The fire extinguishing module is used to quickly start when the temperature data value reaches the set temperature threshold and the smoke concentration data value at more than one position reaches the set smoke concentration threshold to prevent the fire from spreading. The smoke concentration threshold in this embodiment is set to 0.1%, and it can also be higher. The fire extinguishing module includes several fire extinguisher terminals, all of which are electrically connected to the relay. Several fire extinguisher terminals are respectively arranged at the middle position of the car body, the power module position, the vehicle working power position, the fuel tank position, the engine position and the rear tire position (non-fuel vehicles do not include the fuel tank position and the engine position). When a fire occurs, the fire extinguisher terminal at the corresponding position can be quickly started to achieve fixed-point fire extinguishing. The starting device of each fire extinguisher terminal is connected to an electronic pin, which is electrically connected to the relay. After the electronic pin receives the instruction transmitted by the relay, the internal trigger mechanism pushes its pin out, opens the starting device of the fire extinguisher terminal, and makes the fire extinguishing agent of the fire extinguisher terminal spray through the nozzle under pressure to extinguish the fire. The fire extinguisher terminal does not exclude independent fire extinguisher modules similar to the prior art, but in order to save vehicle space and optimize pipeline layout, all fire extinguisher terminals in this embodiment are connected to the same fire extinguishing medium bin through pipelines, so that the fire extinguishing medium bin can be placed in a position that does not affect driving, such as the trunk, under the seat, etc., which also ensures safety in use. The start of the fire extinguisher terminal is controlled by an electronic pin, replacing the traditional mechanical pin or pull ring, to achieve automatic fire extinguishing without manual operation. At the same time, the opening of each fire extinguisher terminal can be precisely controlled, which improves the intelligence of the system. The fire extinguishing medium bin is equipped with a pressure sensor, and a pressure loss warning is issued through the control module. The control module also collects the factory information of the fire extinguishing module and the fire extinguishing medium filling information and issues a failure warning.

[0050] The relay is used to realize automatic control of the cooling module and the fire extinguishing module. The push rod transmission assembly and the exhaust assembly are electrically connected to a set of normally open contacts of the relay. When the control module determines that cooling is required, it sends a signal to the relay, and the relay closes the normally open contacts connected to the push rod transmission assembly and the exhaust assembly, thereby further sending a signal to the push rod transmission assembly and the exhaust assembly. The electronic pin and the fire extinguisher terminal are electrically connected to another set of normally open contacts of the relay. The electronic pin is used to open the fire extinguisher terminal at the corresponding position. When the smoke concentration data value at a certain position reaches the set smoke concentration threshold and there is a risk of fire, the control module sends a signal to the relay, and the relay closes the normally open contacts connected to the electronic pin and the fire extinguisher terminal, triggering the electronic pin to open the fire extinguisher terminal for fire extinguishing.

[0051] The alarm module is used to send out an audible and visual alarm signal when the vehicle cooling and self-ignition prevention system detects an abnormal situation, and to warn people in and around the vehicle. The alarm module includes an alarm horn and an alarm indicator light. When the temperature in the vehicle is too high or the smoke concentration is too high, the alarm horn sounds an alarm and the alarm indicator light flashes. The alarm indicator light used in this embodiment is a red LED indicator light.

[0052] The communication module is used to realize the wireless communication function, and sends the real-time position and alarm information of the vehicle to the external fire department or emergency rescue center so that they can respond quickly. The communication module is specifically a Bluetooth device.

[0053] The power module is used to provide a stable power supply for the entire system to ensure that all components can work normally. Moreover, as a practical design consideration, a power switching control circuit is set for the sunroof assembly and exhaust assembly of the combined ventilation module, so that the sunroof assembly and exhaust assembly can switch power between the power module and the vehicle's working power supply. This allows drivers and passengers to use the sunroof assembly and exhaust assembly in normal vehicle use, and automatically switch to a mode powered by the power module in a cooling and anti-spontaneous combustion defense state after the vehicle is turned off.

[0054] The positioning module is used to obtain the real-time position information of the vehicle body and provide accurate position data for the communication module. In this embodiment, the positioning module is a GPS positioning chip.

[0055] The working indicator light is electrically connected to the control module and is used to display the working status of the vehicle cooling and anti-spontaneous combustion system. When the temperature data value collected by the monitoring module does not exceed the set temperature threshold and the smoke concentration data value does not exceed the smoke concentration threshold, the working indicator light is always on. In this embodiment, the working indicator light is a green LED indicator light.

[0056] In addition, the existing similar vehicle cooling and fire prevention systems do not monitor and eliminate exogenous temperature rise or ignition factors, and there is a risk of mistakenly opening windows for ventilation when the vehicle is exposed to a dangerous environment. As a further improvement, we have also added an external sensor to monitor the external ambient temperature and smoke concentration of the sunroof in the new generation system to collect trigger judgment data for the vehicle cooling and fire prevention system. The command of the push rod transmission component to push the sunroof open will only be executed when the external ambient temperature and smoke concentration of the sunroof do not exceed the set environmental threshold.

[0057] In summary, the vehicle cooling and self-ignition prevention system provided by the embodiment of the present invention realizes comprehensive monitoring of the vehicle state by automatically monitoring the temperature and smoke concentration in the vehicle body and obtaining the real-time position of the vehicle body, and automatically starts corresponding cooling and fire-fighting measures according to the monitoring results. When the temperature is too high, the system can automatically start cooling measures to reduce the temperature. When smoke is detected, it further triggers fire-fighting measures to deal with potential fire risks, which can effectively prevent the occurrence or spread of fire, has a fast response speed, and a high degree of integration and automation. Furthermore, by setting smoke sensors at different positions in the vehicle body, the impact of air flow on smoke detection is reduced, ensuring that all areas are monitored, and improving the accuracy of fire judgment. The vehicle body cooling and spontaneous combustion prevention system provided in the embodiment of the present invention integrates real-time monitoring, early warning and control, and realizes electrical isolation and remote control through relay control elements to ensure the safety of operators. Through the alarm and communication functions, the system can promptly remind the attention of relevant personnel and assist firefighters in responding quickly. The intelligent vehicle body cooling and spontaneous combustion prevention system improves the safety and reliability of the system, and is particularly suitable for industrial applications such as the development of new energy and new vehicle models, infield vehicle customization, and can also be modified and renovated for existing vehicle models.

[0058] The above is a preferred embodiment of the present invention, but the present invention is not limited to the above embodiments and examples. Various changes, equivalent substitutions, improvements, etc. made within the scope of knowledge of those skilled in the art without departing from the concept of the present invention should be included in the protection scope of the present invention.
