Fire prevention system and extinguishing method for electric vehicle parking spaces Technical Field
[0001] This application claims priority to U.S. Provisional Application No. 63 / 755,176, filed February 6, 2025, the entire contents of which are incorporated herein by reference.
[0002] This invention relates to the technical field of fire protection systems, and more particularly to a fire prevention system for electric vehicle parking spaces, which can automatically prevent the fire from spreading when the electric vehicle battery catches fire, and can automatically extinguish the fire on the electric vehicle. Background Technology
[0003] The automotive industry has now shifted its focus to electric vehicle technology, with various automakers launching a variety of electric vehicles for consumers to choose from. Electric vehicles are powered by electricity, which drives the motor to generate power. To maintain range and high power, current technology requires the use of lithium batteries to store electrical energy, which can then be recharged using charging stations when the battery is depleted.
[0004] However, existing automotive lithium batteries consist of hundreds of cells connected in series and parallel. If even one cell malfunctions, there is a risk of spontaneous combustion. Factors such as overcharging, external short circuits, internal short circuits, or overheating can all lead to this danger. Once an electric vehicle's lithium battery catches fire, a high-temperature thermal runaway will form inside the metal casing, and the fire will continue to burn as long as oxygen remains. Existing fire extinguishers are insufficient to penetrate the protective lithium battery casing; the fire will only be completely extinguished after all thermal runaway reactions have subsided. Allowing a burning electric vehicle to continue igniting could spread to other nearby cars or even cause a fire in a parking lot.
[0005] Furthermore, existing automotive fire suppression systems and devices are primarily designed for traditional internal combustion engine vehicles, and face numerous challenges and limitations when dealing with the increasing prevalence of electric vehicles:
[0006] Insufficient fire extinguishing efficiency: The capacity and extinguishing ability of traditional car fire extinguishers cannot meet the needs of electric vehicles. The amount of extinguishing water or chemical agent required when an electric vehicle catches fire is more than 40 times that of a traditional car, which makes common handheld or fixed fire extinguishers extremely ineffective when dealing with electric vehicle fires.
[0007] 2. Low space utilization: Existing parking lot fire suppression systems typically require a large installation space, which contradicts the increasingly scarce space resources and high-density parking demands of modern cities. Large fire suppression equipment is difficult to deploy effectively in limited parking spaces, reducing parking efficiency.
[0008] 3. Incompatible with modern parking environments: With the increasing prevalence of automobiles and higher urban population density, modern parking lots often feature compact designs. However, traditional fire suppression systems are not optimized for this high-density environment and are difficult to deploy and operate effectively in the confined space of parking spaces.
[0009] 4. Lack of Specificity: Most existing fire suppression systems are of general design and fail to fully consider the specific fire suppression needs of electric vehicles, such as the cooling and isolation of the battery pack and the isolation of surrounding oxidizers and oxygen. This results in poor effectiveness in dealing with electric vehicle fires and may cause secondary disasters.
[0010] 5. Long response time: In densely parked environments, traditional fire suppression systems may struggle to quickly reach the fire source. This increases the risk of fire spread, especially considering the rapid spread of fire once an electric vehicle battery catches fire.
[0011] In summary, existing vehicle fire extinguishing technologies are significantly inadequate when dealing with electric vehicles and fail to meet the safety requirements of modern urban parking lots. This highlights the urgent need to develop new fire extinguishing devices and systems specifically designed for electric vehicles and adapted to modern compact parking environments. Furthermore, how to automatically detect a fire in the event of battery spontaneous combustion in an electric vehicle parked in a parking space, and to control or even extinguish the fire directly, preventing it from spreading to nearby vehicles or buildings, is also a problem that this invention aims to actively overcome. Summary of the Invention
[0012] In view of the aforementioned problems with the spontaneous combustion of lithium batteries in existing electric vehicles, the patent applicant, recognizing their shortcomings, devoted considerable effort to researching and overcoming these issues. Drawing upon years of accumulated experience in this industry, they developed a fire prevention device and system for electric vehicle parking spaces. This system achieves the beneficial effects of automatically detecting electric vehicle battery fires, effectively preventing the spread of fires, and automatically extinguishing fires. Furthermore, when not activated, this fire prevention device and system can be installed in parking lots with minimal space requirements, adapting to modern compact parking environments.
[0013] The main objective of this invention is to provide a fire prevention system for electric vehicle parking spaces. The system includes an extendable and deployable fireproof cloth that surrounds and covers the electric vehicle parked on the parking platform, as well as an automatic fire detection module. This system can automatically detect fires when an electric vehicle spontaneously combusts, and cover the electric vehicle with the fireproof cloth to block air and smoke, thereby further preventing the fire from spreading.
[0014] To achieve the above objectives, a specific embodiment of the electric vehicle parking space fire prevention system of the present invention includes: a parking platform, a storage body, a first arm device, a second arm device, and a sensing module. The parking platform comprises two long sides and two short sides. The storage body is disposed on one of the short sides of the parking platform and is used to store a folded fireproof cloth therein, wherein the fireproof cloth is composed of silica, Teflon, or a mixture of both. The first arm device is disposed on one of the long sides of the parking platform and is connected to a portion of the fireproof cloth, and the second arm device is disposed on the other long side of the parking platform and is connected to another portion of the fireproof cloth. The sensing module is disposed on the parking platform. When the sensing module detects a fire on the electric vehicle on the parking platform, the sensing module generates a sensing signal to the first or second arm device, and drives the first and second arm devices to pull the fireproof cloth out from the storage body along the two long sides of the parking platform, unfolding it to cover the entire electric vehicle and prevent external air from entering.
[0015] The electric vehicle parking space fire prevention system of this invention can detect flames or high temperatures when the battery of an electric vehicle catches fire and spontaneously combusts. It generates a sensing signal and transmits the signal to a first or second arm device, causing the first or second arm device to operate and further expand the fireproof cloth to completely cover the burning electric vehicle. At the same time, it can also transmit the signal to the building's fire protection system or a separately installed sprinkler system to spray fire extinguishing agent on the electric vehicle inside the fireproof cloth. This achieves the functions of automatically detecting the fire, completely covering the electric vehicle with the fireproof cloth to prevent the entry of external combustion air and the spread of dense smoke to prevent the fire from spreading, and automatically spraying fire extinguishing agent to extinguish the fire.
[0016] In another specific embodiment, the parking platform further includes a mounting slot for accommodating the storage body or the first arm device or the second arm device.
[0017] In another specific embodiment, the robotic arm of the first arm device or the second arm device is foldable or extendable.
[0018] In another specific embodiment, the mounting groove is a rectangular groove that is recessed downward from around the parking platform. The first arm device or the second arm device is fixed in the rectangular groove so that the first arm device or the second arm device can be hidden around the parking platform when not in use, keeping the surface of the parking platform flat.
[0019] In another specific embodiment, the mounting groove is a rectangular groove that is recessed downwards from around the parking platform. The storage body is fixed in the rectangular groove so that when the fireproof cloth is not in use and is folded and stored in the storage body, it can be hidden on one side of the parking platform, keeping the surface of the parking platform flat.
[0020] In another specific embodiment, a U-shaped channel steel is provided on one side of the parking platform, which forms the mounting groove for the fireproof ring.
[0021] In another specific embodiment, a cover plate is provided on one side of the mounting slot. One side of the cover plate has a rotatable pivot, and the other side can be lifted upward when the fire protection system of the electric vehicle parking space is activated. This achieves the protective effect of covering the mounting slot under normal circumstances, and also allows it to be pushed open by the first arm device, the second arm device, or the fireproof cloth.
[0022] In another specific embodiment, the above-mentioned fire prevention system for electric vehicle parking spaces also includes a controller, which is electrically connected to the first arm device and the second arm device. A user can manually activate the first arm device and the second arm device through the controller, so that the fire prevention system of the present invention can be activated manually when the power is off, thereby achieving a more effective fire prevention effect.
[0023] In another specific embodiment, the above-mentioned fire prevention system for electric vehicle parking spaces also includes a spraying device. This spraying device has a liquid pump, a delivery pipe, and spray heads, enabling the sensing module or controller to synchronously control the spraying device to spray extinguishing agent onto the burning electric vehicle. The liquid pump is electrically connected to the sensing module.
[0024] In another specific embodiment, one spraying direction of the spray head is toward a battery module of the electric vehicle.
[0025] In another specific embodiment, the extinguishing agent includes water or fire-fighting foam.
[0026] In another specific embodiment, the above-mentioned fire prevention system for electric vehicle parking spaces also includes an alarm device, which is electrically connected to the first arm device and the second arm device. The alarm device is a fire alarm or a fire alarm control panel, thereby achieving the effect of notifying personnel to evacuate and handling emergencies.
[0027] In another specific embodiment, in the above-mentioned fire prevention system for electric vehicle parking spaces, the sensing module includes an infrared sensor or a smoke sensor, and the sensing module is installed at any location in the electric vehicle parking space.
[0028] In another specific embodiment, the controller in the above-mentioned electric vehicle parking space fire prevention system also includes a communication interface, and is connected to the building fire protection system or fire department through the communication interface, so as to notify the building manager or fire brigade personnel for emergency handling.
[0029] In another specific embodiment, in the above-mentioned electric vehicle parking space fire prevention system, the sensing module can be installed in a charging pile, so that the present invention can be combined with the electric vehicle charging pile to achieve the effect of combining charging and fire protection functions.
[0030] Another major objective of this disclosure is to provide a fire extinguishing method, which mainly utilizes the aforementioned electric vehicle parking space fire prevention system. This system includes an electric vehicle parking platform with an extendable and deployable fireproof cloth that surrounds and covers the electric vehicle parked on the platform, as well as an automatic detection module for detecting electric vehicle fires. This allows the system to automatically detect the fire when an electric vehicle spontaneously combusts, cover the electric vehicle with the fireproof cloth to block air and smoke, and further prevent the fire from spreading.
[0031] To achieve the above objectives, a specific embodiment of the fire extinguishing method of the present invention includes the following steps:
[0032] A sensing module is used to detect a condition of an electric vehicle parked on a parking platform;
[0033] The sensing module generates a sensing signal to a first arm device or a second arm device and drives the first arm device or the second arm device, when the condition meets a preset condition; and
[0034] The first and second arm devices are used to pull a folded fireproof cloth out from a storage body and unfold it to cover the electric vehicle and prevent outside air from entering.
[0035] In another specific embodiment, the step of lifting the cover of the mounting slot upwards is included before step (C).
[0036] In another specific embodiment, step (D) is included after step (C): spraying a fire extinguishing agent onto a battery module of the electric vehicle using the spraying device. Attached Figure Description

[0046] Figure 1 illustrates a fire prevention system 1 for a parking space of an existing vehicle 21 (electric or gasoline vehicle). Installed on a parking space, it provides a dedicated parking space / platform 41 for the vehicle 21. In the event of a fire in the vehicle 21, it automatically activates to prevent the fire from spreading and can automatically extinguish the fire or notify personnel to take emergency measures. It is worth noting that existing parking platforms can generally be divided into outdoor and indoor types. Outdoor parking platforms do not have a dedicated external fire prevention system; instead, they only have fire hydrants or fire extinguishers installed in one location within the parking lot to prevent the fire from spreading. However, this method cannot provide a real-time and effective fire extinguishing method, and if the fire source cannot be extinguished initially, it will further spread to nearby vehicles, causing a larger and more uncontrollable disaster.
[0047] As mentioned earlier, another type of indoor parking platform is the indoor parking lot. The parking platform 41 shown in Figure 1 is an example of an indoor parking platform. Some existing indoor parking platforms are equipped with a parking space fire suppression system 1, as shown in Figure 1, above each parking platform 41. Each parking space fire suppression system 1 includes a plurality of sprinkler heads 113 and an infusion pipe 115, wherein the infusion pipe 115 connects the plurality of sprinkler heads 113 in series and is connected to a water source and a sensor (not shown in the figure). When the sensor detects a fire source, the parking space fire suppression system 1 can be activated to extinguish the fire on the burning vehicle 21. However, the disadvantages of the existing parking space fire suppression system 1 shown in Figure 1 include: 1) it takes up space, and 2) it is only suitable for conventional gasoline vehicles and not for electric vehicles. To further explain the drawback of space occupation: since the sprinkler heads are installed in the ceiling space above each parking platform 41, the existing parking space fire protection system 1 is limited by the indoor height. In other words, if the indoor parking platform is located in a basement or a place with a low single floor height, the existing parking space fire protection system 1 cannot be used because the space occupied by the sprinkler heads 113 and the infusion pipes 115 will make it impossible to park the car 21.
[0048] Furthermore, the existing parking space fire prevention system 1 has the drawback of being only applicable to conventional gasoline vehicles and not electric vehicles. In conventional gasoline vehicles, the ignition point is mostly at the fuel tank or engine compartment. Therefore, the sprinkler heads 113 in the existing parking space fire prevention system 1 are mostly installed on the ceiling so that they can spray water directly from above the fuel tank or engine compartment for effective fire suppression. However, in electric vehicles, the ignition point is mostly at the battery module. Generally, the battery module of most electric vehicles is located on their chassis, while the corresponding location for the fuel tank or engine compartment in gasoline vehicles is usually the trunk. Therefore, using the parking space fire prevention system 1 cannot directly spray water at the fire source of the electric vehicle, and by the time the fire spreads above the electric vehicle, the fire is already out of control and may have already affected nearby vehicles. According to statistics, the amount of water required to extinguish a fire in an electric vehicle is 40 times that required to extinguish a fire in a conventional gasoline vehicle. Therefore, considering all the above, using the existing parking space fire prevention system 1 to extinguish fires in electric vehicles is highly inefficient.
[0049] On the other hand, both traditional gasoline-powered vehicles and electric vehicles produce large amounts of dense smoke when they catch fire. While existing parking space fire prevention systems 1 can continuously spray water on burning vehicles, they cannot effectively isolate the dense smoke. Therefore, there is still a certain danger for firefighters entering indoor parking platforms to assist in firefighting, or for the general public escaping from indoor parking platforms, as they may be injured by the dense smoke. Therefore, in order to address the increasing prevalence of electric vehicles and overcome the shortcomings of existing parking space fire prevention systems 1, which are unsuitable for electric vehicles, this invention provides an electric vehicle parking space fire prevention system that offers: 1) more effective fire extinguishing capabilities and benefits, 2) space saving, and 3) reduced smoke diffusion.
[0050] Please refer to Figure 2, which shows a specific embodiment of a parking space fire prevention system 3 for electric vehicles disclosed in this invention. It is noteworthy that the parking space fire prevention system 3 for electric vehicles disclosed in Figure 2 is in a standby state, meaning that the electric vehicle 211 parked on the parking platform 41 has not caught fire. This invention applies the following to the parking space fire prevention system 3 for electric vehicles: a parking platform 41, a storage body 31, a first arm device 33, a second arm device 35, and at least one sensing module (not shown). The parking platform 41 can be a platform composed of steel plates and steel bars, or a general parking space made of cement, with dimensions approximately equal to existing parking spaces, typically equal to the size of the parking space grid lines, and can be fixed to existing parking spaces. However, those skilled in the art can further adjust the size or material of the parking platform 41 to meet different needs. In this embodiment, at least one sensing module is positioned above the parking platform 41, adjacent to or directly opposite the chassis of the electric vehicle 211, to facilitate direct and interference-free measurement of at least one conditional factor (e.g., chassis temperature) of the electric vehicle 211, or at least one environmental factor (e.g., ambient temperature, humidity, smoke, particulate matter) near the electric vehicle 211. Therefore, the at least one sensing module can be an infrared sensor or a smoke sensor, etc. In another specific embodiment (not shown), the sensing module is positioned at a first location on the storage body 31, the first arm device 33, or the second arm device 35, and the distance between this first location and the plane of the parking platform 41 is less than the distance between the chassis of the electric vehicle 211 and the plane of the parking platform 41. In yet another specific embodiment (not shown), the sensing module is positioned not only on the parking platform 41 but also at the first location on the storage body 31, the first arm device 33, or the second arm device 35, and the distance between this first location and the plane of the parking platform 41 is less than the distance between the chassis of the electric vehicle 211 and the plane of the parking platform 41. In another specific embodiment (not shown in the figure), in addition to being set in the possible positions described above, the parking space fire prevention system 3 of the present invention also includes at least one other sensing module set in a second position, and the distance between the second position and the plane of the parking platform 41 is greater than the distance between the chassis of the electric vehicle 211 and the plane of the parking platform 41.
[0051] On the other hand, as shown in Figures 2 and 3 below, the storage body 31 is located on one of the two short sides of the parking platform 41, and this storage body 31 is used to store a folded fireproof cloth 39. The folded fireproof cloth 39 is a shield made of fire-resistant, airtight, but water-permeable fabric, such as a high-temperature resistant Teflon bag, a shield made of silica, or a single or multiple layer shield made of a mixture of silica and Teflon, etc. Its unfolded size and shape correspond to the shape of the electric vehicle 211, or can completely cover the electric vehicle 211. More importantly, the fireproof cloth 39 can withstand a heat resistance temperature of at least 1000 degrees Celsius. Additionally, the unfolded fireproof cloth 39 can be folded and embedded in the storage body 31 in a compressed state (as shown in Figure 3). In this specific embodiment, the storage body 31 has a foldable and upward-opening top cover 311, and the top cover 311 consists of a front cover 3111 and a rear cover 3113. Therefore, when the top cover 311 is lifted upward via the hinge 313, the front cover 3111 and the rear cover 3113 can be further folded together to save space. When the parking space fire protection system 3 is not activated (i.e., in normal standby mode), the top cover 311 covers the storage body 31, thus protecting and preventing the fireproof cloth in the storage body 31 from being soiled or damaged by environmental or human factors.
[0052] Furthermore, referring to Figure 2, the first arm device 33 includes: a first upper cover 331, a first body 333, and a first arm (not shown), wherein the first arm (not shown) can be stored in the first body 333, and the first upper cover 331 is pivotally connected to a long side of the first body 333 and can be opened upwards. The second arm device 35 includes: a second upper cover 351, a second body 353, and a second arm (not shown), wherein the second arm can be stored in the second body 353, and the second upper cover 351 is pivotally connected to a long side of the second body 353 and can be opened upwards. Further, the first arm device 33 and the second arm device 35 are respectively adjacent to the storage body 31 disposed on a short side of the parking platform 41.
[0053] Please refer to Figures 2 and 4 below. Figure 4 shows another specific embodiment of a parking space fire prevention system 3 for electric vehicles disclosed in this invention. The device composition of the parking space fire prevention system 5 in Figure 4 is the same as that of the parking space fire prevention system 3 in Figure 2. However, the difference between the parking space fire prevention system 3 and the parking space fire prevention system 5 is that the parking platform 41 in the parking space fire prevention system 5 also includes mounting grooves 51 and 52. The mounting grooves 51 and 52 are rectangular grooves (i.e., the dotted lines in Figure 4) that are recessed downwards and surround the storage body 31, the first arm device 33, or the second arm device 35 on each side of the parking platform 41. In another specific embodiment, each side of the storage body 31, the first arm device 33, or the second arm device 35 around the parking platform 41 is provided with a U-shaped channel steel, and the recessed space of the U-shaped channel steel allows the storage body 31, the first arm device 33, or the second arm device 35 around the parking platform 41 to be embedded therein. As mentioned above, the storage body 31, the first arm device 33, and the second arm device 35 may each include an upper cover 311, a first upper cover 331, and a second upper cover 351, respectively, to cover the storage body 31, the first arm device 33, and the second arm device 35, and further keep the surface of the storage body 31, the first arm device 33, and the second arm device 35 and the parking platform 41 flat.
[0054] As described above, each of the top cover 311, the first top cover 331, and the second top cover 351 has at least one rotatable pivot portion on one side. These pivot portions movably connect the top cover 31, the first top cover 331, and the second top cover 351 to one side of the housing body 31, the first arm device 33, and the second arm device 355, respectively. This allows the top cover 311, the first top cover 331, and the second top cover 351 to normally cover the mounting grooves 51 and 52 (U-shaped channel steel), while the other side of the top cover 311, the first top cover 331, and the second top cover 351 can be lifted upwards. In another specific embodiment, the parking space fire prevention system 5 only includes the mounting groove 51 to embed the first arm device 33 and the second arm device 35 on the two long sides of the parking platform 41. In another specific embodiment, one or both ends of the parking platform 41 may be provided with a ramp (not shown in the figure) for electric vehicles to drive into the parking platform 41 when parking. In another specific embodiment, the housing body 31, the first arm device 33, and the second arm device 35 do not have top covers 311, 331, and 351 respectively, which are pivotally connected to one side. However, one side of the mounting grooves 51 and 52 (U-shaped channel steel) is provided with a cover plate. One side of the cover plate has a rotatable pivot part, and the other side can be lifted upward when the fire protection system of the electric vehicle parking space is activated.
[0055] Please refer to Figures 5-7 below, which illustrate specific embodiments of the operation of the parking space fire prevention system 5 for electric vehicles according to the present invention. Referring first to Figure 5, at this time, the parking space fire prevention system 5 is in standby mode, meaning the sensing module on the parking platform 41 has not detected any fire or spontaneous combustion in the chassis, battery module, or other parts of the electric vehicle 211. Therefore, neither the first arm device 33 nor the second arm device 35 is activated, and the folded fireproof cloth remains stored in the storage body 31. Further, referring to Figure 6, at this time, the sensing module on the parking platform 41 detects a fire or spontaneous combustion in the chassis, battery module, or other parts of the electric vehicle 211 and activates the parking space fire prevention system 5, simultaneously transmitting a signal to the first arm device 33 or the second arm device 35, or both, thus activating one of the robotic arms. As shown in Figure 6, one end of the first arm 335 in the first arm device 33 and one end of the second arm 355 in the second arm device 35 are connected to the fireproof cloth 39. Therefore, when the first arm 335 and the second arm 355 rise or extend from the first arm device 33 and the second arm device 35 respectively, they will pull the folded fireproof cloth 39 out of the storage body 31 and unfold it. It is worth noting that, in a preferred embodiment, when the parking space fire prevention system 5 starts the first stage, the first arm 335 and the second arm 355 extend and rise from the first arm device 33 and the second arm device 35 respectively, such that the angle between the first arm 335 and the second arm 355 and the first arm device 33 and the second arm device 35 is about 45 to 90 degrees, preferably 60 to 90 degrees. At this time, the distance between the highest point 391 of the stretched fireproof cloth 39 and the parking platform 41 is slightly greater than the distance between the roof of the electric vehicle 211 and the parking platform 41. Furthermore, as shown in Figure 7, the parking space fire prevention system 5 activates its second stage. The first arm 335 and the second arm 355 pull the fireproof cloth 39 horizontally along the first arm device 33 and the second arm device 35 for a certain distance, so that the unfolded fireproof cloth 39 can at least cover the roof of the electric vehicle 211. Further, as shown in Figure 8, the parking space fire prevention system 5 activates its third stage. The first arm 335 and the second arm 355 move towards the plane of the parking platform 41 to pull the fireproof cloth 39 to completely cover the remaining part of the electric vehicle 211 outside the fireproof cloth 39. Finally, the entire electric vehicle 211 is completely covered by the fireproof cloth 39, thus preventing air from entering the fireproof cloth and preventing the outside air from fueling combustion. In addition, another unintended effect is preventing the fire from spreading to other vehicles or buildings.
[0056] Please refer to Figure 9 below, which is a flowchart illustrating the operation of the parking space fire prevention system 5 for the electric vehicle disclosed in Figures 5-7. As shown in Figure 5, the parking space fire prevention system 5 is in standby mode at this time. The parking space fire prevention system 5 executes step (A): using a sensing module to detect a condition of the electric vehicle 211 parked on the parking platform 41, such as detecting the temperature, infrared radiation, and smoke of the chassis or battery module of the electric vehicle 211. Further, when the sensing module detects this condition, the parking space fire prevention system 5 executes step (B): determining whether the condition meets a preset condition. This default condition is that the aforementioned temperature, infrared radiation, and smoke conditions meet the conditions for the electric vehicle 211 to spontaneously combust or be about to spontaneously combust. If the measured condition does not meet the preset condition, the parking space fire prevention system 5 continues to activate the sensing module and execute the aforementioned step (A). If the measured condition meets the preset condition, as shown in Figure 6, the sensing module generates a sensing signal to the first arm device or the second arm device, and drives the first arm device or the second arm device to start. More specifically, the first arm 335 in the first arm device 33 and the second arm 355 in the second arm device 35 are both activated. Next, the parking space fire prevention system 5 starts the first stage. The first cover 331 of the first arm device 33 and the second cover 351 of the second arm device 35 are both flipped upwards. The first arm 335 and the second arm 355 extend from the first arm device 33 and the second arm device 35 respectively and pull out the folded fireproof cloth 39. Next, as shown in Figures 7 and 8, the first arm 335 and the second arm 355 pull the fireproof cloth 39 to cover the entire electric vehicle 211 and block the entry of external air, so as to extinguish the fire and prevent the smoke from the fire from spreading to the environment outside the fireproof cloth 39. In another specific embodiment, the first arm device or the second arm device does not include a first top cover or a second top cover, and the first arm device and the second arm device are respectively embedded in a mounting groove, and the mounting groove has a cover plate on one side, the cover plate having a rotatable pivot portion on one side. Therefore, before the parking space fire protection system 5 starts the first stage (i.e., when the first arm device or the second arm device is started), the sensing module generates a sensing signal to the mounting groove to cause its cover plate to be lifted upward.
[0057] Please refer to Figure 10 below. Figure 10 shows another specific embodiment of the electric vehicle parking space fire prevention system 7 of this disclosure. This parking space fire prevention system 7 is similar to the device modules of the parking space fire prevention system 5, but further includes a controller 61. The controller 61 is the main circuit board or logic controller for controlling the electric vehicle parking space fire prevention system 7 of this disclosure. Specifically, it can be housed in a housing, forming a control box or control host. As mentioned above, the sensing module 37 can be located at the first position, which can be on the surface of the parking platform 41. In another specific embodiment, the first position of the sensing module is located above or to the side of the housing body 31, the first arm device 33, and the second arm device 35, and then connected to the controller 61 to transmit the signal of a detected electric vehicle fire to the controller 61, causing the controller 61 to execute control of the first arm device 33 and the second arm device 35 to operate separately or simultaneously according to the program settings. Therefore, in this specific embodiment (see Figure 10), the controller 61 is electrically connected to the first arm device 33 and the second arm device 35 respectively. In another specific embodiment, the sensing module 37 may also be located in the same position as the controller 61, or integrated with the controller 61.
[0058] Please refer to Figure 11 below. Figure 11 shows another specific embodiment of the electric vehicle parking space fire prevention system 7 of the present invention. The parking space fire prevention system 7 also includes a pump 71, which is an air compressor or a liquid pump, and is electrically connected to the controller 61. When the sensing module 37 detects a fire in the electric vehicle, it transmits a signal to the controller 61, causing the controller 61 to further execute the control of the pump 71 according to the program settings, that is, to push a fire extinguishing agent through the infusion pipe 115 to deliver it to the sprinkler head 113 to extinguish the fire in the electric vehicle. In this specific embodiment, the sprinkler head 113 is located above the electric vehicle. In another preferred embodiment, the plurality of sprinkler heads 113 located above the electric vehicle also include a plurality of sensing modules 37 for detecting smoke or temperature. In another preferred embodiment, the sprinkler head 113 is located on the parking platform 41. Therefore, when the controller 61 further executes the control of the pump 71 according to the program settings, that is, pushes a fire extinguishing agent to be delivered through the infusion pipe 115 to the sprinkler head 113 to spray and extinguish the fire on the electric vehicle, the fire extinguishing agent sprayed by the sprinkler head is directly sprayed onto the burning battery module or the chassis of the electric vehicle, thereby achieving the best fire extinguishing effect. In another specific embodiment, the sensing module in the parking space fire prevention system 7 is directly electrically connected to the pump 71, without the need for the controller 61. Therefore, referring to Figure 9, in this specific embodiment (i.e., the sensing module in the parking space fire prevention system 7 is directly electrically connected to the pump 71), step (D) is followed by step (E): using the spraying device to spray a fire extinguishing agent onto the battery module of the electric vehicle. More specifically, the sensing module generates a signal to drive the first arm device or the second arm device, which in turn drives the spraying device.
[0059] Please refer to Figure 12 below, which is a block diagram of the various modules of the electric vehicle parking space fire prevention system of the present invention. Furthermore, when an electric vehicle catches fire, the aforementioned controller 61 can connect to the building's fire protection system 81 or the fire department via a communication interface to activate the building's fire protection system 81 for water spraying, and simultaneously notify the building manager or fire department personnel for emergency handling. The controller 61 can also control the water spraying device 11, which may be additionally provided in this disclosure, to spray fire extinguishing agent onto the burning electric vehicle. For example, the controller 61 controls the operation of the liquid pump 71 to deliver a liquid (such as water, fire-fighting foam, or other liquid) to the spray head 113, thereby causing the spray head 113 to spray fire extinguishing agent towards the chassis, battery module, or area of the vehicle body covered by fireproof cloth of the electric vehicle, preventing the battery fire from spreading. In another preferred embodiment of the present invention, the parking space fire prevention system 9 further includes an alarm 91, which can be a fire alarm or a fire alarm control panel, etc., and the alarm 91 is electrically connected to the controller 61. When the battery of an electric vehicle catches fire, the fire alarm or fire alarm control panel can be automatically controlled to sound an alarm, and personnel can be notified to evacuate and handle the situation in real time. It is worth mentioning that existing electric vehicle parking spaces are equipped with dedicated charging piles. The various module units of the present invention can be combined and installed in the charging piles to form a charging pile that combines charging and fire protection functions.
