[0026] The embodiments of the present disclosure provide a vehicle fire emergency handling system and an unmanned vehicle. The preferred embodiments of the present disclosure are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present application can be combined with each other if there is no conflict.
[0027] The present disclosure provides a vehicle fire emergency handling system. Figure 1 As shown, it includes: a battery box 10, which is arranged on the vehicle, and the battery box 10 is used to accommodate and protect the battery unit; wherein the battery box 10 includes:
[0028] A first detection device 101, the first detection device 101 is used to detect smoke and / or fire in the battery box 10;
[0029] The first fire extinguishing device 102 is associated with the first detecting device 101 , and is used to be activated to extinguish the fire when the first detecting device 101 detects smoke and / or fire in the battery box 10 .
[0030] In the disclosed embodiment, a battery box 10 can be provided on the vehicle, and the battery unit can be placed in the battery box 10. At the same time, a first detection device 101 can be provided in the battery box 10 to monitor the working state of the battery in real time. For example, characteristic physical quantities (including but not limited to smoke concentration and / or fire conditions, etc.) that can reflect the fire state in the battery box 10 can be monitored. In order to be able to respond promptly to a possible fire, a first fire extinguishing device 102 can also be provided in the battery box 10, so that it can be opened in time to extinguish the fire when the first detection device 101 detects the presence of smoke and / or fire in the battery box 10.
[0031] In order to enable the first fire extinguishing device 102 to respond to the detection result of the first detection device 101 in a timely manner, the first detection device 101 and the first fire extinguishing device 102 need to be associated. In a possible implementation, a first controller (such as a microcontroller unit (MCU)) can be set, and an intelligent switch (such as a relay) can be connected to the pin of the MCU as the switch of the first fire extinguishing device 102. If the first detection device 101 detects a fire in the battery box 10, the detected physical signal can be converted into an electrical signal and sent to the MCU. The MCU can directly control the first fire extinguishing device 102 to extinguish the fire through the pin control, so that the fire can be responded to in a timely manner at the first time, and the danger to the vehicle can be minimized.
[0032] In another embodiment provided by the present disclosure, Figure 2 As shown, the system further includes: a battery bracket 201 for forming a battery compartment 2011 for placing the battery box 10, and the battery bracket 201 is connected to the body of the vehicle.
[0033] In the disclosed embodiment, in order to connect the battery box 10 to the body of the vehicle, a battery bracket 201 may be provided, the exterior of the battery bracket may be connected to the body of the vehicle, and the interior may form a battery compartment for accommodating the battery box 10 . Figure 2 In the exemplary embodiment, the battery bracket 201 is connected to the vehicle frame 203 through the battery bracket 202. During implementation, the battery bracket 201 can be set at other positions of the vehicle as needed, which is not limited here.
[0034] In another embodiment provided by the present disclosure, Figure 3As shown, the battery compartment 2011 includes:
[0035] A second detection device 301, the second detection device 301 is used to detect smoke and / or fire in the battery compartment 2011;
[0036] The second fire extinguishing device 302 is associated with the second detection device 301 , and is used to be activated to extinguish the fire when the second detection device 201 detects smoke and / or fire in the battery compartment 2011 .
[0037] In the disclosed embodiment, the first line of defense, i.e., the battery box 10, is firstly provided for the battery. The first detection device 101 in the battery box 10 monitors the fire condition of the battery box 10, and extinguishes the fire through the first fire extinguishing device 102 in the battery box 10 after detecting the fire condition. Once the first line of defense is breached, i.e., the fire extinguishing device 102 fails to control the fire, the second line of defense, i.e., the battery compartment 2011, can also be provided for the battery. Once the fire breaks through the battery box 10 and spreads to the battery compartment 2011, the fire condition spreading to the battery compartment 2011 can also be monitored by the second detection device 301 provided in the battery compartment 2011. For example, the characteristic physical quantity (including but not limited to the smoke concentration and / or the fire condition, etc.) that can reflect the fire condition in the battery compartment 2011 can be monitored. In order to be able to respond to the possible fire condition in time, the second fire extinguishing device 302 can also be provided in the battery compartment 2011, so that it can be opened in time to extinguish the fire when the second detection device 301 detects the presence of smoke and / or fire condition in the battery compartment 2011.
[0038] In addition, the second fire extinguishing device 302 and the second detection device 301 also need to be associated. The association method can refer to the association method between the first detection device 101 and the first fire extinguishing device 102, that is, setting a second controller, which will not be repeated here.
[0039] It can be seen that in this embodiment, a battery compartment 2011 and a second fire extinguishing device 302 and a second detection device 301 therein are provided for the battery, which adds another safety line for the battery and further increases the safety of the vehicle.
[0040] In another embodiment provided by the present disclosure, the first detection device 101 includes a first smoke detector and / or a first fire detector; and / or,
[0041] The second detection device 301 includes a second smoke detector and / or a second fire detector.
[0042] In the disclosed embodiment, the first detection device 101 can monitor characteristic physical quantities in the battery box 10 that can reflect the fire state, and can be implemented as a first smoke detector and / or a first fire detector. The first smoke detector can detect the smoke concentration in the battery box 10, that is, detect the concentration of smoke emitted when the battery is thermally runaway, and the first fire detector can detect the fire situation when the battery catches fire in the later stage of thermal runaway (for example: the fire situation can be monitored by taking images through a camera, or the temperature under different fire conditions can be monitored through a temperature sensor, or the light intensity under different fire conditions can be monitored through a radiation light intensity sensor, etc.). In addition, it can also cooperate with the first controller at the same time. The first smoke detector and / or the first fire detector can send the detection results to the first controller, and the first controller determines whether to control the opening of the first fire extinguishing device 102 to extinguish the fire based on the detection results.
[0043] Similarly, the second detection device 301 can monitor the characteristic physical quantities in the battery compartment 2011 that can reflect the fire state, and can be implemented as a second smoke detector and / or a second fire detector. The second smoke detector can detect the smoke concentration in the battery compartment 2011, that is, detect the smoke coming out of the battery box 10. The second fire detector can detect the fire situation when the battery catches fire in the late stage of thermal runaway (for example: as above, different fires can be monitored through a camera, a temperature sensor, or a radiation light intensity sensor, etc.). In addition, it can also cooperate with the second controller at the same time. The second smoke detector and / or the second fire detector can send the detection results to the second controller, and the second controller determines whether to control the second fire extinguishing device 302 to extinguish the fire based on the detection results.
[0044] In another embodiment provided by the present disclosure, Figure 4 As shown, the first fire extinguishing device 102 includes a first fire extinguishing pipe 1021 and at least one first fire extinguishing nozzle 1022, and the first fire extinguishing pipe 1021 is connected to the at least one first fire extinguishing nozzle 1022; and / or,
[0045] The second fire extinguishing device 302 includes a second fire extinguishing pipe 3021 and at least one second fire extinguishing nozzle 3022 , and the second fire extinguishing pipe 3021 is connected to the at least one second fire extinguishing nozzle 3022 .
[0046] In the disclosed embodiment, the first fire extinguishing pipe 1021 can be used to transport the fire extinguishing agent for fire extinguishing, and spray it to the battery box 10 through the first fire extinguishing nozzle 1022. Similarly, the second fire extinguishing pipe 3021 can be used to transport the fire extinguishing agent for fire extinguishing, and spray it to the battery compartment 2011 through the second fire extinguishing nozzle 3022.
[0047] In addition, the layout of the first fire extinguishing pipe 1021 and the second fire extinguishing pipe 3021 can be set according to actual conditions, and the number of the first fire extinguishing nozzle 1022 and the second fire extinguishing nozzle 3022 can be set according to actual conditions, and there is no limitation here. In a possible implementation, a first fire extinguishing nozzle 1022 can be arranged at each of the four corners of the battery box 10, and similarly, a second fire extinguishing nozzle 3022 can be arranged at each of the four corners of the battery compartment 2011.
[0048] In another embodiment provided by the present disclosure, Figure 4 As shown, the system also includes a gas tank 401, and the first fire extinguishing pipe 1021 is connected to the second fire extinguishing pipe 3021 through the gas tank 401; wherein, the high-pressure gas in the gas tank 401 sprays the fire extinguishing agent through at least one first fire extinguishing nozzle 1022 to the battery box 10 for fire extinguishing; the high-pressure gas in the gas tank 401 sprays the fire extinguishing agent through at least one second fire extinguishing nozzle 3022 to the battery compartment 2011 for fire extinguishing.
[0049] In the embodiment of the present disclosure, high-pressure gas can be released through the gas storage tank 401, and the fire extinguishing agent in the first fire extinguishing pipeline 1021 and / or the second fire extinguishing pipeline 3021 can be driven by the pressure to spray through the corresponding fire extinguishing nozzles. Figure 4 As shown, a gas tank 401 can be provided to connect the first fire extinguishing pipe 1021 and the second fire extinguishing pipe 3021. The gas tank 401 can drive the fire extinguishing agent in the first fire extinguishing pipe 1021 or the second fire extinguishing pipe 3021 alone, or can drive the fire extinguishing agent in the first fire extinguishing pipe 1021 and the second fire extinguishing pipe 3021 at the same time. This can be achieved by designing the internal structure of the gas tank 401, which will not be repeated here.
[0050] Furthermore, when a fire is detected in the battery box 10 and needs to be extinguished, the first controller can drive the fire extinguishing agent in the first fire extinguishing pipe 1021 by controlling the gas tank 401 to spray the battery box 10 for fire extinguishing. Similarly, when a fire is detected in the battery compartment 2011 and needs to be extinguished, the second controller can drive the fire extinguishing agent in the second fire extinguishing pipe 3021 by controlling the gas tank 401 to spray the battery compartment 2011 for fire extinguishing. The gas tank 401 can also be controlled to simultaneously drive the fire extinguishing agents in the first fire extinguishing pipe 1021 and the second fire extinguishing pipe 3021 to spray the corresponding areas.
[0051] In addition, the location of the gas storage tank 401 can be set according to actual conditions. Figure 4 The gas storage tank 401 is disposed in the battery compartment 2011, and can also be disposed in the battery box 10 during implementation, which will not be described in detail here.
[0052] In another embodiment provided by the present disclosure, Figure 2As shown, the battery bracket 201 is fixed to the vehicle via a locking structure 204; wherein, when the second fire extinguishing device 302 fails to extinguish the fire, the locking structure 204 separates the battery bracket 201 from the vehicle.
[0053] In this embodiment, a third line of defense is provided for protecting the vehicle. When the fire spreads to the battery compartment 2011 and the second fire extinguishing device 302 in the battery compartment 2011 fails to extinguish the fire, the fire can be prevented from spreading to other parts of the vehicle by separating the battery bracket 201 from the vehicle.
[0054] In the related art, the battery bracket and the vehicle frame are usually bolted and cannot be separated quickly, which makes the battery fire eventually spread to other parts of the vehicle, causing the vehicle to be completely scrapped and causing huge economic losses. In the disclosed embodiment, the battery bracket 201 is fixed to the vehicle through the locking structure 204, and the VCU can control the locking structure 204 to unlock, complete the mechanical separation of the battery bracket 301 from the vehicle frame, and can use external force to lift the battery bracket 301 together with the burning battery to complete the separation from the vehicle, and carry out fire extinguishing at a safe distance from the vehicle to minimize the loss of the vehicle.
[0055] Furthermore, the number of locking structures 204 can be set according to actual needs. Figure 2 The two settings are only examples and do not limit the present disclosure.
[0056] In yet another embodiment provided by the present disclosure, the locking structure 204 includes a pneumatic locking structure.
[0057] In the disclosed embodiment, the locking structure 204 may also be implemented as a slider locking structure, a rotation locking structure, etc., which is not limited here.
[0058] In another embodiment provided in the present disclosure, the pneumatic locking structure includes a cylinder and a locking component. The pneumatic locking structure supplies air to the cylinder to move the locking component to a fixed position or a releasable position, thereby achieving the fixation and separation of the battery bracket 201 from the vehicle.
[0059] In this embodiment, the air supply of the cylinder can be controlled by the VCU, thereby controlling the locking or separation of the battery bracket 201 from the vehicle body.
[0060] In another embodiment provided by the present disclosure, the system further includes: an interface locking module, which is used to be in an unlocked state when the second fire extinguishing device 302 fails to extinguish the fire, so as to unlock the interface between the vehicle and the battery unit.
[0061] In the disclosed embodiment, in addition to completing the mechanical separation of the battery bracket 301 from the vehicle frame, it is also necessary to complete the unlocking of the high and low pressure and water channel quick plug interfaces between the battery unit and the high voltage load of the vehicle, the main purpose of which is to complete the interface separation. Only in this way can the battery unit be completely separated from the vehicle and the safety of other parts of the vehicle be ensured.
[0062] An embodiment of the present disclosure provides an unmanned vehicle, comprising a vehicle fire emergency handling system as described in any of the above embodiments.
[0063] The vehicle fire emergency handling system provided by the present invention can trigger three-level protection step by step when a battery unit catches fire due to thermal runaway, and perform fire handling and mechanical separation from three dimensions: extinguishing the fire inside the battery box 10, extinguishing the fire inside the battery compartment 2011 (battery bracket 201), and separating the battery bracket 201 from the mechanical interface of the whole vehicle, thereby minimizing the loss of the whole vehicle caused by battery combustion and having good economic benefits.
[0064] Figure 5 The fire extinguishing logic flow chart of the vehicle fire emergency disposal system provided by the present disclosure is as follows: Figure 5 As shown, when the battery has thermal runaway->the battery management system (BMS) first detects abnormal battery voltage and temperature->reports a serious battery system fault->requests the vehicle VCU to limit the charge and discharge to 0, the power of the drive motor drops to 0 within 5s, and the vehicle is under high voltage->the VCU performs an emergency stop based on the report; at the same time, when the battery has thermal runaway->heat diffusion will produce smoke and fire->at this time, the smoke detector, fire detector, and first controller in the battery box 10 form a first-level protection system to spray and extinguish the fire at the fire location->if the fire is extinguished, the process ends; if the fire is large and overflows from the battery box 10->at this time, the smoke detector, fire detector, and second controller in the battery compartment 2011 form a second-level fire extinguishing system to spray and extinguish the fire at the fire location The sprinkler head in the battery compartment has a larger flow rate and a wider spraying range -> If the fire is extinguished, this process ends; if it is not extinguished, the current status is sent to the vehicle VCU -> The vehicle VCU triggers the third-level protection system, controls the pneumatic locking structure to unlock, and completes the mechanical separation of the battery bracket and the vehicle frame -> The high and low pressure and water quick-plug interfaces between the battery system and the high-voltage load of the vehicle are unlocked. The main purpose of this step is to complete the interface separation -> At this time, the battery bracket is completely mechanically separated from the vehicle. The battery bracket can be hoisted down together with the burning battery with the help of external force to complete the separation from the vehicle, and the fire is extinguished at a safe distance from the vehicle to minimize the loss of the vehicle.
