Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Combination Figure 1 and Figure 2 An embodiment of this application provides a fire extinguishing device for new energy vehicles, including a fire extinguishing component 100 and a water-filled bag component 200.

[0023] The fire extinguishing assembly 100 is used to cover the fire area; the water bag assembly 200 is connected to the bottom of the fire extinguishing assembly 100 and extends around the bottom of the fire extinguishing assembly 100. The water bag assembly 200 is configured to form a water storage structure after being filled with water.

[0024] Understandably, when a vehicle, such as a new energy vehicle, catches fire, the fire extinguishing component 100 can be used to cover the vehicle, and then water can be filled into the water-filled bag component 200. Since the water-filled bag component 200 is connected to the bottom of the fire extinguishing component 100, the filled water-filled bag component 200 will surround the vehicle and form a water storage structure. The space enclosed by the water-filled bag component 200 (in conjunction with the ground) can be used to store water, thereby immersing the vehicle's power battery to achieve the effects of cooling, suppressing thermal runaway of the power battery, and extinguishing the fire.

[0025] It should be noted that the water-filled bag assembly 200 in this application is lightweight before being filled with water, and it can be folded after being installed on the fire extinguishing assembly 100, thus occupying little space. After being filled with water, the water-filled bag assembly 200 can form a stable water storage structure by means of the weight of the water.

[0026] It should be noted that the water-holding bag component 200 can be made of high-temperature resistant or flame-retardant materials, which have high heat resistance and are more reliable.

[0027] Combination Figure 2 and Figure 3 The fire extinguishing device for new energy vehicles also includes a connector 300, which is detachably connected to the fire extinguishing component 100 and / or the water bag assembly 200. When the fire extinguishing component 100 is supported on a support surface (e.g., the ground): when the connector 300 is connected to the fire extinguishing component 100 and the water bag assembly 200, the bottom end of the water bag assembly 200 is higher than the support surface; when the connector 300 is separated from the fire extinguishing component 100 and / or the water bag assembly 200, the water bag assembly 200 can fall onto the support surface due to gravity.

[0028] like Figure 2 , Figure 4 As shown, it can be understood that when the water bag assembly 200 is not in use, the connector 300 connects the fire extinguishing assembly 100 and the water bag assembly 200 together. At this time, the bottom of the water bag assembly 200 is higher than the supporting surface (ground), which facilitates the overall movement of the fire extinguishing assembly 100. During the movement of the fire extinguishing assembly 100, the water bag assembly 200 will not rub against the supporting surface. When the water bag assembly 200 needs to be used, the connector 300 separates from the fire extinguishing assembly 100 and / or the water bag assembly 200. The connector 300 loses its supporting function for the water bag assembly 200. After the water bag assembly 200 is filled with water, it adheres to the supporting surface under the action of gravity. The water bag assembly 200, in conjunction with the supporting surface, can be used to store water.

[0029] Furthermore, when the connector 300 is connected to the fire extinguishing assembly 100 and the water bag assembly 200, the water bag assembly 200 is in a folded state, with its bottom edge connected to the fire extinguishing assembly 100 and its top edge connected to the connector 300. It is understood that when the water bag assembly 200 is not needed, it can be folded up first, and then the connector 300 can provide tension to the water bag assembly 200, allowing it to be folded and mounted on the fire extinguishing assembly 100, thus reducing space occupation.

[0030] Specifically, the connector 300 includes a first connecting part 310 and a second connecting part 320. The first connecting part 310 is used to connect with the fire extinguishing assembly 100, and the second connecting part 320 is used to connect with the water bag assembly 200. The first connecting part 310 is located above the second connecting part 320.

[0031] The connector 300 is configured such that, during the filling of the water bag assembly 200, the first connector 310 and / or the second connector 320 fail as the amount of water in the water bag assembly 200 increases.

[0032] Specifically, the connector 300 can be a snap-fit, with its first connecting portion 310 snapping into the fire extinguishing component 100 and its second connecting portion 320 snapping into the water bag assembly 200. During the filling process of the water bag assembly 200, as the weight of the water inside the water bag assembly 200 increases, one of the first connecting portion 310 and the second connecting portion 320 will fail first, causing the water bag assembly 200 to fall onto the supporting surface (ground). In this way, there is no need for relevant personnel to disassemble the connector 300 beforehand, thus speeding up the firefighting efficiency. In other embodiments, the connector 300 can be a Velcro strap.

[0033] It should be noted that the water bag assembly 200 is equipped with a water outlet, which has a removable sealing plug. After the firefighting is completed, the sealing plug can be removed to drain the water from the water bag assembly 200.

[0034] Specifically, the water outlet is located at the bottom of the water bag assembly 200. Of course, the water bag assembly 200 is also provided with a water inlet, which can be located at the top of the water bag assembly 200.

[0035] Combination Figure 1 and Figure 2 In some embodiments, the fire extinguishing assembly 100 includes a frame assembly 110 and a fire extinguishing cover 120 connected to the frame assembly 110. A water bag assembly 200 is connected to the bottom of the fire extinguishing cover 120 and extends around the bottom of the fire extinguishing cover 120. It is understood that the frame assembly 110 supports the fire extinguishing cover 120, which can cover the burning vehicle, effectively isolating it from the air and extinguishing the fire. The fire extinguishing cover 120 can be made of a high-temperature resistant material. Figure 4 and Figure 5 The fire extinguishing cover 120 is connected to the frame assembly 110 via a hook 122.

[0036] It should be noted that the bottom of the frame assembly 110 is provided with casters 113, which makes it easy to move to the fire area.

[0037] Furthermore, the frame assembly 110 is provided with a water inlet channel, which is connected to the water inlet of the water bag assembly 200. The water inlet channel of the frame assembly 110 can be used to connect with a fire hose. After the fire hose is filled with water, water can be filled into the water bag assembly 200 through the water inlet channel.

[0038] like Figure 6 As shown, the water-filled bag assembly 200 further includes multiple water-filled bags 210, which are arranged sequentially around the bottom of the fire extinguishing assembly 100. The multiple water-filled bags 210 are configured to form a water storage structure after being filled with water. The water-filled bags 210 are made of flame-retardant material and are also provided with an inspection port 212. Each water-filled bag 210 is provided with a water inlet and a water outlet 211. The new energy vehicle fire extinguishing device also includes a connecting pipe 220, which is connected to the water inlet channel of the frame assembly 110 and is also connected to the water inlet of each water-filled bag 210.

[0039] Combination Figure 1 and Figure 2In some embodiments, the frame assembly 110 includes two first foldable assemblies 111 arranged side by side and spaced apart along a first direction, and a second foldable assembly 112 connected between the two first foldable assemblies 111. The first foldable assemblies 111 can be folded or unfolded along a second direction, and the second foldable assembly 112 can be folded or unfolded along the first direction. The first direction is perpendicular to the second direction and both are parallel to the horizontal plane. The fire extinguishing cover 120 is connected between the two first foldable assemblies 111.

[0040] It is understood that when the fire extinguishing device for new energy vehicles of this application is not in use, the frame assembly 110 can be folded along the first and second directions to reduce the space occupied; when it is in use, the frame assembly 110 can be unfolded, and the two first foldable assemblies 111 are respectively placed on both sides of the burning vehicle, and the fireproof cover covers the vehicle.

[0041] like Figures 7 to 10 As shown, the first foldable assembly 111 further includes a plurality of vertical support rods 1111 arranged side by side and spaced apart along the second direction, and a foldable linkage mechanism 1112 disposed on the plurality of vertical support rods 1111.

[0042] Specifically, the foldable linkage mechanism 1112 is used to connect multiple vertical support rods 1111 together, and the foldable linkage mechanism 1112 can bring the multiple vertical support rods 1111 closer together or separate, thereby realizing the folding or unfolding of the first foldable component 111 in the second direction.

[0043] Furthermore, the foldable linkage mechanism 1112 includes a plurality of vertical guide rods 11121 spaced apart along the second direction. Two connecting rods 11122 are provided between each pair of adjacent vertical guide rods 11121. Specifically, the two connecting rods 11122 are arranged in an 'X' shape, and the middle part of one connecting rod 11122 is rotatably connected to the middle part of the other connecting rod 11122. One end of one connecting rod 11122 is rotatably connected to one of the vertical guide rods 11121, and the other end is rotatably connected to a first sliding sleeve 11123. The first sliding sleeve 11123 is in sliding engagement with the other vertical guide rod 11121. One end of the other connecting rod 11122 is rotatably connected to one of the vertical guide rods 11121, and the other end is rotatably connected to a second sliding sleeve 11124. The second sliding sleeve 11124 is in sliding engagement with the other vertical guide rod 11121.

[0044] like Figure 2 As shown, in some embodiments, the second foldable component 112 is a scissor structure used to connect the two first foldable components 111 and can be folded or unfolded.

[0045] Combination Figure 4 and Figure 5 Furthermore, all vertical support rods 1111 are hollow structures with water flow channels, and the inner side of each vertical support rod 1111 has a spray nozzle communicating with the water flow channel. Specifically, the vertical support rod 1111 has a structure that is sealed at both ends and hollow inside, with a water flow channel inside, and the inner side of each vertical support rod 1111 has a spray nozzle communicating with the water flow channel. It should be noted that the inner side of the vertical support rod 1111 refers to the side closer to the other first foldable component 111.

[0046] like Figure 5 As shown, it should be noted that the fire extinguishing cover 120 is provided with through holes 121 opposite to each spray nozzle. This prevents the fire extinguishing cover 120 from obstructing the water sprayed from the spray nozzles from reaching the fire area. A spray pipe can be connected to each spray nozzle, and the spray pipe passes through the through holes 121 of the fire extinguishing cover 120. It is understood that the water sprayed through the spray nozzles can be accumulated within the water storage structure formed by the water bag assembly 200.

[0047] It should be noted that the water flow channels of each vertical support rod 1111 also serve as water inlet channels for injecting water into the water bag assembly 200, and the water flow channels are also connected to the water bag assembly 200.

[0048] Furthermore, the fire extinguishing device for new energy vehicles also includes a fire hose (not shown), which is connected to the frame assembly 110 and is connected to the water flow channels of multiple vertical support rods 1111 on the first foldable assembly 111.

[0049] Understandably, the fire hose circulates water through the multiple vertical supports 1111 on the first foldable assembly 111. When water is flowing through, it enters the water flow channels of each vertical support 1111 along the fire hose and is then sprayed out through the nozzles to achieve the effect of extinguishing the fire.

[0050] A water inlet pipe connector can be installed on at least one vertical support rod 1111. The water inlet pipe connector can be connected to a water inlet pipe. When the water inlet pipe is connected to the water inlet pipe connector, the water inlet pipe is connected to the water flow channel of each vertical support rod 1111 and the fire hose. The water in the water inlet pipe can be injected into the fire extinguishing device to achieve the effect of spraying water.

[0051] The fire hose includes multiple connecting sections; in the same first foldable assembly 111, among the multiple vertical support rods 1111, a connecting section is connected between every two adjacent vertical support rods 1111, and the connecting section communicates with the water flow channels of the two vertical support rods 1111 connected to it. In this way, in each first foldable assembly 111, the water flow channels of the multiple vertical support rods 1111 within the first foldable assembly 111 can be connected by means of the connecting sections.

[0052] Multiple vertical support rods 1111 are equipped with adapters 114. The connecting sections between two adjacent vertical support rods 1111 are respectively connected to the adapters 114 of the two adjacent vertical support rods 1111, so that the connecting sections and the water flow channels of the two vertical support rods 1111 connected thereto are connected.

[0053] When a vehicle, such as a new energy vehicle, catches fire, the fire extinguishing component 100 can be moved to cover the vehicle. Water is then injected into the fire hose, causing water to spray from the fire extinguishing component 100. Simultaneously, water is filled into the water-filled bag assembly 200. Since the water-filled bag assembly 200 is connected to the bottom of the fire extinguishing component 100, the filled water-filled bag assembly 200 will surround the vehicle and form a water storage structure. The space enclosed by the water-filled bag assembly 200 (in conjunction with the ground) can be used to collect the sprayed water, thereby immersing the vehicle's power battery to achieve the effects of cooling, suppressing thermal runaway of the power battery, and extinguishing the fire.
