Description

Technical Field

[0001] The utility model relates to the field of fire extinguishing equipment, in particular to a vehicle-mounted fire extinguishing inflation system. Background Art

[0002] Fire extinguishers are a common type of vehicle-mounted equipment. When a vehicle catches fire due to various reasons, such as collision or spontaneous combustion, a fire extinguisher is needed to put out the fire. Most existing vehicle-mounted fire extinguishers are portable, manual fire extinguishers that require pulling out the safety pin and pressing the handle to release the fire extinguishing medium before use. To improve the safety and intelligence of vehicle-mounted fire extinguishing devices, the prior art has also proposed some fire extinguishing devices that can automatically release the fire, such as the automatic spray-type fire extinguisher for vehicles disclosed in Chinese patent document CN103961830 A and the automatic fire extinguishing device for electric vehicles disclosed in Chinese patent document CN109045513 A.

[0003] Whether manually or automatically, fire extinguishers can leak when subjected to impact or vibration (e.g., bottle breakage, seal failure, etc.). Leaked extinguishing medium can cause discomfort to vehicle occupants, and in severe cases, even suffocation, especially if occupants are unable to evacuate in time (e.g., resting in the vehicle or being impeded by a traffic accident). Therefore, improvements to existing fire extinguishers are needed.

[0004] In addition, in recent years, due to the surge in rainfall during the rainy season, drainage facilities have been unable to drain rainwater in a timely manner, resulting in flooding of vehicles in many low-lying areas (low-lying roads, underground parking lots, etc.), causing damage to vehicles and even casualties on board. Prior application CN 209813905 U proposed a car flood prevention device that generates buoyancy by inflating airbags to allow the vehicle to float on the water surface, thereby avoiding flooding. Airbags are generally inflated by dedicated air pumps. On the one hand, the inflation speed of small air pumps is limited. On the other hand, placing an air pump and a fire extinguisher in the car at the same time will take up more space and increase the cost for users. Utility Model Content

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0026] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," "connect," "fix," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Figure 1 and Figure 2An embodiment of the vehicle-mounted fire extinguishing and inflation system of the present utility model is shown. The vehicle-mounted fire extinguishing and inflation system of this embodiment includes a fire extinguisher 1 and an openable sealed container 2. The fire extinguisher 1 is disposed within the sealed container 2, which is connected to a discharge pipe 3 for discharging any fire extinguishing medium leaking from the fire extinguisher 1 to the exterior of the vehicle. Preferably, the fire extinguisher 1 is disposed in the vehicle trunk, with one end of the discharge pipe 3 connected to the sealed container 2 and the other end mounted to the ventilation valve of the vehicle body, thus avoiding the need for additional holes in the vehicle body and reducing modification workload.

[0029] The vehicle-mounted fire extinguishing and inflation system of this embodiment can be used to open the sealed container 2 and take out the fire extinguisher 1 when a fire needs to be extinguished; when an accident occurs and the fire extinguishing medium of the fire extinguisher 1 leaks, the fire extinguishing medium enters the sealed container 2, which can play a sealing and buffering role, and then the fire extinguishing medium is discharged through the discharge pipe 3 to avoid leakage into the interior of the vehicle, thereby ensuring the safety of people in the vehicle, and the structure is simple and the cost is low.

[0030] In a preferred embodiment, the sealed container 2 is a sealed bag. After the fire extinguisher 1 is placed in the sealed bag, the bag is sealed and then collapsed and folded. This reduces the space occupied in the vehicle. If the fire extinguishing medium leaks, the sealed bag can be squeezed and expanded, providing a good buffer. The sealed bag can be a plastic bag, and the bag opening can be sealed using a hot melt, adhesive, or plastic sealing strip. When extinguishing a fire, the plastic sealing strip can be opened or the bag can be directly cut open to remove the fire extinguisher 1.

[0031] Of course, in other embodiments, the sealed container 2 may also be an elastic sealed bag. Because the sealed bag is inherently elastic, it expands and stretches when squeezed by the leaking fire extinguishing medium, thereby providing a good cushioning effect. Specifically, the sealed bag may be a rubber bag, which has better pressure resistance than plastic bags, but is more expensive.

[0032] Of course, in other embodiments, the sealed container 2 may also be a sealed box, which may be a drawer-type structure or have a lid that flips up and down to facilitate the removal of the fire extinguisher 1. Compared to plastic bags and rubber bags, the box is a rigid structure and is not easily damaged, but the cost is higher, and if the vehicle is subjected to a large impact, the box may also be deformed or even damaged.

[0033] Furthermore, in this embodiment, the vehicle-mounted fire extinguishing and inflation system also includes an inflation tube 6 and an anti-flooding airbag 4 for making the vehicle float on the water surface. The fire extinguisher 1 is detachably connected to one end of the inflation tube 6, and the other end of the inflation tube 6 is connected to the anti-flooding airbag 4. In this embodiment, the fire extinguishing medium sprayed by the fire extinguisher 1 is a gas, such as a carbon dioxide fire extinguisher. When it is necessary to extinguish a fire, first open the sealed container 2, then disconnect the inflation tube 6 from the fire extinguisher 1, and then take out the fire extinguisher 1; in rainy weather when the vehicle may be flooded, the fire extinguisher 1 can be opened, and the fire extinguishing medium in the fire extinguisher 1 can be quickly sprayed and quickly inflated into the anti-flooding airbag 4 through the inflation tube 6, thereby making the vehicle float on the water surface. The fire extinguisher 1 has both fire extinguishing and inflation functions and can replace the existing inflation pump of the anti-flooding airbag 4.

[0034] As a preferred embodiment, the fire extinguisher 1 is connected to the inflation tube 6 by a quick-connect connector (not shown in the figure, but commercially available), which is convenient to connect, has a reliable seal, and can be quickly disassembled when extinguishing a fire. Of course, in other embodiments, the inflation tube 6 and the fire extinguisher 1 can also be connected by a clamp connection, a threaded connection, etc.

[0035] Furthermore, in this embodiment, the fire extinguisher 1 is provided with an opening assembly 5. When a vehicle may be flooded during heavy rain, the opening assembly 5 can be used to automatically open the fire extinguisher 1 and inflate the anti-flooding airbag 4, which is more convenient to use and does not require manual operation.

[0036] Furthermore, in this embodiment, the fire extinguisher 1 includes a body 11, a safety pin 13, and a handle 12. This means that the fire extinguisher 1 utilizes existing vehicle-mounted fire extinguishers, eliminating the need for modifications to the fire extinguisher 1 and reducing costs. The opening assembly 5 includes a first electric push rod 51 for extracting the safety pin 13 and a second electric push rod 52 for pressing the handle 12. To inflate the anti-flooding airbag 4, the first electric push rod 51 first pushes out the safety pin 13, and then the second electric push rod 52 continuously presses the handle 12. This results in a simple and reliable structure.

[0037] Of course, in other embodiments, the fire extinguisher 1 includes a bottle body 11, and the opening component 5 includes an electrically controlled valve (not shown in the figure) provided on the bottle body 11, that is, the safety pin 13 and the handle 12 on the fire extinguisher 1 are eliminated, and the opening of the bottle body 11 is controlled by the electrically controlled valve, and when the anti-flooding airbag 4 is inflated, the electrically controlled valve is opened.

[0038] Furthermore, in this embodiment, the opening component 5 is equipped with a battery 7. When the vehicle encounters an unexpected situation and may lose power, the opening component 5 can be powered by the battery 7, which is more reliable.

[0039] Furthermore, in this embodiment, the inflation tube 6 is passed through the discharge tube 3. Passing the inflation tube 6 through the discharge tube 3 can effectively utilize the space inside the discharge tube 3, reduce the number of holes opened on the sealed container 2, and reduce the difficulty of sealing the sealed container 2.

[0040] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations. Therefore, any simple modifications, equivalent variations, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the scope of protection of the present invention.
