Description

Disaster rescue equipment for new energy vehicles and their underbody fire extinguishing units

The present invention is related to a fire rescue device, in particular a fire rescue device for new energy vehicles powered by batteries.

With the rise of environmental awareness, countries around the world have announced that they will stop selling fuel vehicles, resulting in the emergence of new energy vehicles that use motors as the main driving method on the market. Among them, whether the new energy vehicle adopts pure electric drive or hybrid drive, it will be equipped with at least one battery pack, such as a battery pack composed of multiple 18650 or 21700 lithium batteries connected in series or parallel, as the power source of the motor.

However, considering the safety of the battery pack and the weight of the vehicle, the battery pack is usually installed on the chassis of the new energy vehicle. As a result, when the new energy vehicle is in a car accident and catches fire, fire extinguishing materials, such as fire water jets, fire foam or fire fighting agents, cannot directly cool the battery pack. They can only be poured in large quantities and wait for the battery pack to burn out, which is very time-consuming and wastes fire extinguishing materials. Therefore, after observing the above shortcomings, the inventor of this case believes that it is necessary to develop a disaster relief device for new energy vehicles, which led to the creation of this invention.

The purpose of the present invention is to provide a disaster relief device for new energy vehicles, which can directly cool down the battery pack installed on the chassis of a new energy vehicle, so as to greatly shorten the fire extinguishing time and effectively reduce the use of fire extinguishing materials.

To achieve the above-mentioned purpose, the disaster rescue device for new energy vehicles provided by the present invention includes an in-vehicle fire extinguishing unit and an under-vehicle fire extinguishing unit, wherein the in-vehicle fire extinguishing unit has at least one window breaker and at least one spraying member, and the spraying member has at least one input port for connecting to an external supply source, and at least one output port for outputting the fire extinguishing material of the external supply source, and the under-vehicle fire extinguishing unit is arranged below the in-vehicle fire extinguishing unit, and has at least one connection interface for connecting to the external supply source, and at least one upwardly arranged spraying port for outputting the fire extinguishing material of the external supply source.

The fire-fighting device for new energy vehicles of the present invention can break the window glass of the new energy vehicle through the window breaker when the new energy vehicle catches fire, and pour the fire-fighting material from the external supply source into the interior space of the new energy vehicle through the outlet, or place the underbody fire-fighting unit under the new energy vehicle and pour the fire-fighting material from the external supply source into the interior space of the new energy vehicle. The material is sprayed on the chassis of the new energy vehicle through the spray port, or simultaneously extinguishes the battery pack installed on the chassis of the new energy vehicle through the in-vehicle fire extinguishing unit and the under-vehicle fire extinguishing unit. In this way, the battery pack can be effectively cooled and extinguished, and the fire extinguishing time and the amount of fire extinguishing material used can be greatly shortened.

In order to further understand the features, technical means and expected effects of the present invention, the use of the present invention is described below. It is believed that this will provide a deeper and more specific understanding of the present invention, as described below: Please refer to Figure 7, which is a schematic diagram of the use of the first preferred embodiment of the present invention. When a new energy vehicle 200 is on fire, the user can connect the input connector 21 of the supply unit 20 to the external supply source. In this embodiment, the external supply source is a fire hose 300, and the fire extinguishing material is water. Then, the vehicle 10 is started and moved closer to the new energy vehicle 200. Then, the window glass 201 of the new energy vehicle 200 is broken by the window breaker 42, and then the window breaker 42 is used to break the window glass 201 of the new energy vehicle 200. The in-vehicle fire extinguishing unit 40 is inserted into the window of the new energy vehicle 200, and the water provided by the fire hose 300 is poured into the indoor space of the new energy vehicle 200 through the output port 432 of the spraying member 43. At the same time, the under-vehicle fire extinguishing unit 50 is pushed into the underbody of the new energy vehicle 200, and the water provided by the fire hose 300 is poured into the indoor space of the new energy vehicle 200 through the output port 513 of the spraying member 43. The chassis of the new energy vehicle 200 is sprayed with the fire extinguishing material, thereby spraying the fire extinguishing material from top to bottom at the same time, so that the fire extinguishing material can directly cool the battery pack 202 installed on the chassis of the new energy vehicle 200, so as to quickly reduce the burning battery pack 202 to a safe temperature, thereby greatly shortening the fire extinguishing time and effectively reducing the amount of the fire extinguishing material used.

It is worth mentioning that in order to improve the success rate of breaking the window, as shown in FIG. 3, the user can first compress the sliding member 423 toward the elastic member 422 and fix it with the stopper 425. In this way, when the sliding member 423 abuts against the window glass 201, the stopper 425 can be released to drive the sliding member 423 to impact the window glass 201 by the thrust of the elastic member 422, so that the sliding member 423 can break through the window glass 201. The window glass 201 can also be operated by the vehicle 10 to slightly move backward through the design of the hook 424 to pull the window glass 201 out of the window of the new energy vehicle 200, thereby ensuring that the window breaker 42 can successfully break the window glass 201. On the other hand, since the window breaker 42 is a purely mechanical structure, there is no concern of fire even if it is operated near the new energy vehicle 200 that is burning.

It is worth mentioning that the top surface of the plate 51 is provided with the spraying surfaces 512, and the spraying surfaces 512 are located at different horizontal planes. At the same time, the spraying ports 513 are vertically arranged with the corresponding spraying surfaces 512, so that the spraying directions of the spraying ports 513 located at different spraying surfaces 512 are different from each other. Thus, when the spraying ports 513 are spraying the fire extinguishing material, they can spray the chassis of the new energy vehicle 200 at multiple angles in different directions, which will increase the spraying range and area to obtain better fire extinguishing efficiency.

In addition, it must be explained that the carrier 10 can be in other forms, such as a cart or a support frame. The unmanned self-propelled vehicle used in this embodiment is only a preferred embodiment and does not limit the patent scope of the present invention. In some use environments, the carrier 10 can be omitted, and the user can only use the in-vehicle fire extinguishing unit 40 and the under-vehicle fire extinguishing unit 50 to achieve the purpose of spraying the fire extinguishing material from top to bottom at the same time. As an extension of the application, the user can also use the in-vehicle fire extinguishing unit alone. 40, or using the undercar fire extinguishing unit 50 alone, or using the vehicle 10 in combination with the in-car fire extinguishing unit 40, or using the vehicle 10 in combination with the undercar fire extinguishing unit 50. These methods can allow the fire extinguishing material to directly cool the battery pack 202 installed on the chassis of the new energy vehicle 200, so as to quickly reduce the burning battery pack 202 to a safe temperature, thereby greatly shortening the fire extinguishing time and effectively reducing the amount of the fire extinguishing material used.

Please refer to Figure 8 again, which is a schematic diagram of the use of the first preferred embodiment of the present invention. Since the sliding frame 32 of the carrier unit 30 can slide up and down along the fixed frame 31, in addition to being able to adjust the height position of the in-vehicle fire extinguishing unit 40 according to the window height of the new energy vehicle 200, in normal times, the user can also remove the in-vehicle fire extinguishing unit 40 and the under-vehicle fire extinguishing unit 50 from the carrier unit 30, and slide and fold the sliding frame 32 as shown in the figure, so that the volume of the carrier 10 can be effectively reduced to achieve the effect of convenient transportation.

Please refer to Figure 9 again, which is a side view of the second preferred embodiment of the present invention. The new energy vehicle disaster relief device 100 is different from the aforementioned first embodiment in that the carrier 10 is further provided with a protection unit 60 to protect the carrier 10 from being damaged by the high temperature generated by the flame. In this embodiment, the protection unit 60 is a fireproof baffle disposed in front of the carrier 10, but this does not limit the patent scope of the present invention. Those skilled in the art can use other methods to achieve the same effect, such as using a water spraying device to continuously spray water to cool the carrier 10.

Here, the features of the present invention and its expected effects are described as follows: When the new energy vehicle 200 is on fire, the fire rescue device 100 of the new energy vehicle 200 can break the window glass 201 of the new energy vehicle 200 through the window breaker 42, and pour the fire extinguishing material from the external supply source into the indoor space of the new energy vehicle 200 through the output port 432, or place the underbody fire extinguishing unit 50 on the new energy vehicle 200. The fire extinguishing material from the external supply source is sprayed on the chassis of the new energy vehicle 200 through the spray port 513, or the battery pack 202 disposed on the chassis 200 of the new energy vehicle is sprayed from top to bottom simultaneously through the in-vehicle fire extinguishing unit 40 and the under-vehicle fire extinguishing unit 50, thereby effectively cooling down and extinguishing the fire of the battery pack 202, and significantly shortening the fire extinguishing time and significantly reducing the amount of the fire extinguishing material used.

In summary, this invention has excellent advancement and practicality among similar products. At the same time, after searching domestic and foreign technical data on this type of structure, no similar structure has been found in the literature. Therefore, this invention has the patent requirements and is filed in accordance with the law.

However, the above is only a preferred embodiment of the present invention. Therefore, any equivalent structural changes made by applying the present invention specification and the scope of patent application should be included in the patent scope of the present invention.
