    Description

    BACKGROUND



    [0001] The present disclosure relates to safety accessories pertaining to electric motor vehicles and more particularly, to a fire extinguisher cover that extinguishes fire emanating from the batteries of an electric vehicle.

    [0002] In a prior art reference, CN201098486Y of Liu Bo, discloses a fire extinguisher cover for covering over motor vehicle in heat distress. The cover comprises a sheet having zipper and snap mechanism enabling it to form a flameproof enclosure for the vehicle, wherein the bottom of the enclosure can be fully contacted with the ground so as to prevent supplement of surrounding air and combustion-supporting action of wind power to carry out fire smothering. The sheet comprises at least one opening disposed thereon used for injecting carbon dioxide into the enclosure so as to extinguish fire in the enclosure.

    [0003] In another prior art reference, CN1 06693233A of Taiyuan Nuoya Science & Tech Co. Ltd, discloses a portable car fire-extinguishing device comprising a folded wrap cover that is arranged to be opened into an umbrella shape. The cover comprises a fireproof cloth and supporting gas prism which is evenly distributed on, and adhered to, the outer surface of the fireproof cloth. The gas prism is sealed between an outlet of a gas generator and an air intake port of the supporting gas prism. The fireproof cloth may be made into a shape to just cover the car, and to provide no ventilation. When the cover is to be applied to cover the car on fire, an electric ignition device is activated to generate support gas prism and then start to open valve for a fire extinguishing agent cylinder. The gas rushes into the supporting gas prism, and the gas prism expands so that the fireproof cloth is extended into the umbrella shape. A valve at the top of the wrap cover is then opened, and the fire extinguishing agent is sprayed into the housing to extinguish the fire.

    [0004] Lithium-ion battery (or batteries) are nested within electric vehicles such that, they are quite difficult to access. Said difficulty escalates to impossibility when said battery catches fire. Fire emanating from lithium-ion battery is virtually unstoppable as (a) as mentioned earlier, the battery is inaccessible and (b) the fire, which is aided by high voltage, cannot be choked by cutting off oxygen. The battery needs to be cooled down to a minimum of 120°C first as quickly as possible in order for the fire to be taken out.

    SUMMARY OF THE INVENTION



    [0005] This summary is provided to introduce a selection of concepts in a simplified form that are further disclosed in the detailed description of the invention. This summary is neither intended to identify key or essential inventive concepts of the claimed subject matter, nor is it intended for determining the scope of the claimed subject matter.

    [0006] An embodiment of the present invention is directed to a fire extinguisher cover for a motor vehicle in heat-distress. The motor vehicle is an electric motor vehicle in heat-distress, wherein battery (or batteries) is on fire. The objective of the cover is to bring down the temperature of the battery to a safe level as quickly as possible and then proceed to extinguish the fire. The cover made of fire-resistant material or materials.

    [0007] The cover comprises a rectangular sheet and a casing assembly integrally attached to the rectangular sheet. The sheet comprises a pair of openings disposed thereon. The casing assembly comprises a plurality of elongate casings disposed on the bottom surface of the sheet wherein, the casings are adapted to run a drawstring therethrough. The plurality of casing is arranged close to an outer edge of the sheet around a whole circumference of the sheet. The casings are divided into longitudinal casings, which are disposed closer to the longitudinal edges of the sheet, transverse casings, which are disposed closer to the longitudinal edges of the sheet, and oblique corner casings disposed between longitudinal and transverse casings. The drawstring is arranged to be tightened to achieve a tight abutment between the casing assembly, the ground and the vehicle tires when the vehicle is covered by the sheet. Then, the fire-extinguishing fluid is run through the at least one opening to fill up between the vehicle and the sheet resulting in said fluid reaching the battery for extinguishing the fire emanating therefrom.

    [0008] In order to deploy the cover over a vehicle on fire, the cover is first covered over the vehicle such that the bottom surface of the sheet abuts the vehicle body. Once covered, the cover is snugly secured over the vehicle by tightening the drawstring and locking it in place. More particularly, pulling the drawstring will force the sheet to tighten along the ground towards the tires and create a tightly secured upside-down bag. This causes the substantial edge of the sheet to move inwardly toward the wheels of the vehicle while the rest of it to abut the sides of the vehicle and on the ground. At this point, water is flown in through the openings by means of, say, a fire hose. The weight of the water presses the sheet against the ground whereby the engagement between the sheet and the ground is tightened thereby preventing any leak between the sheet and the ground. The water fills up inside the enclosed blanket until it at least submerges the battery. This results in the battery being cooled down to a safe 120°C and eventually, said water extinguishing remaining fire emanating from the battery.

    [0009] Other objects, features and advantages of the present invention will become apparent from the following detailed description. It should be understood, however, that the detailed description and the specific examples, while indicating specific embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

    DETAILED DESCRIPTION OF THE INVENTION



    [0012] In the following detailed description, a reference is made to the accompanying drawings that form a part hereof, and in which the specific embodiments that may be practiced is shown by way of illustration. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and it is to be understood that the logical, mechanical and other changes may be made without departing from the scope of the embodiments. The following detailed description is therefore not to be taken in a limiting sense.

    [0013] The present invention is directed to a fire extinguisher cover for an electric motor vehicle, the battery (or batteries) of which is on fire. On a side note, said battery usually comprises a Lithium-ion battery. The objective of the cover is to direct the water over and around the battery, which, as mentioned earlier, is on fire. This cools down the battery to a safe temperature as quickly as possible whereafter, the cover facilitates the extinguishing of the fire. For instance, the Lithium-ion battery is known to be unstable when hit or heated of from fire in the car elsewhere. In order to take out the fire, the battery needs to be cooled down to a minimum of 120° Celsius as quickly as possible. The cover is water proof and is additionally made of a fire-resistant material or materials. Further, the cover is also immune to strong voltage as it is coated with an isolating material that resists high voltage.

    [0014] Referring to FIG. 1, the cover 10 comprises a rectangular sheet 12 defined by a pair of opposing longer longitudinal and shorter transverse edges and inner and outer surfaces and a top and a bottom surface. The sheet 12 comprises openings 18 disposed thereon wherein, the utility of the openings 18 will become apparent from the following body of text. The cover 10 further comprises a casing assembly, the function of which is to achieve a tight-abutment between the sheet 12 and the vehicle 20 tires. The casing assembly comprises a plurality of casings 14 that are adapted to run an un-looped drawstring 16 therethrough. The plurality of casing 14 is arranged close to an outer edge of the sheet 12 around a whole circumference of the sheet 12. The drawstring 16 is arranged to be tightened to achieve a tight abutment between the casing assembly, the ground and the vehicle 20 tires when the vehicle 20 is covered by the sheet 12. Then, the fire-extinguishing fluid is filled through at least one opening 18, wherein the fire-extinguishing fluid is filled between the vehicle 20 and the sheet 12 allowing the fluid to reach the battery for extinguishing the fire emanating therefrom.

    [0015] Still referring to FIG. 1, the casings 14 are integrally disposed on the bottom surface of the sheet 12 closer to the edges thereof. The casings 14 comprise elongate longitudinal casings disposed closer to the longitudinal edges of the sheet 12, elongate transverse casings disposed closer to the longitudinal edges of the sheet 12 and oblique corner casings disposed between the longitudinal and transverse casings. The open extremity of each casing 14 is lined with an eyelet 24. Each free end of the drawstring 16 is attached with a handle. The drawstring 16 runs through the casings 14 and each free end thereof extends out of an eyelet 24. More particularly, the handles extend out of opposingly-disposed eyelets 24 wherein, said eyelets 24 pertain to transverse casings 14.

    [0016] Referring to FIGs. 2 through 4, in order to deploy the cover 10, the cover 10 is covered over the vehicle 20 such that, the bottom surface thereof abuts the vehicle 20 body. Once the vehicle 20 covered by cover 10 like an upside-down bag, the handles are pulled outwardly. This causes the casing assembly (and thereby the sheet attached thereto) to tightly abut beneath the vehicle 20 tires forming a water-tight engagement therebetween. More particularly, pulling the handles will force the sheet 12 to tighten along the ground towards the tires and create an upside-down bag where some portions of the top surfaces of the sheet 12 abut the ground. Once tight abutment between the edges of the sheet 12 and the vehicle 20 tires is ascertained, the pulled handles are secured by means of knot, cord locks, or the like.

    [0017] Still referring to FIGs. 2 through 4, at this point, a fire-extinguishing fluid, i.e., water 22, is let into the openings 18 by means of, say, a fire hose. On a side note, the weight of the water pushes the sheet 12 down, which forms a watertight engagement between the cover 10 and the ground. This creates minimum leakage between the ground and the cover 10. Running water 22 through openings 18 results in said water 22, owing to the watertight engagement between the sheet 12, vehicle 20, and the ground, to fill up the enclosed cover 10 and eventually rise to cover the battery. This causes the battery to be cooled down to below 120°C whereafter, the fire emanating therefrom is taken out promptly. The cover 10 is preferably employed by professional firefighters and said cover 10 and gives them a tool that quickly, safely and easily takes out fire.

    [0018] The foregoing examples have been provided merely for the purpose of explanation and are in no way to be construed as limiting of the present concept disclosed herein. While the concept has been described with reference to various embodiments, it is understood that the words, which have been used herein, are words of description and illustration, rather than words of limitation. Further, although the concept has been described herein with reference to particular means, materials, and embodiments, the concept is not intended to be limited to the particulars disclosed herein; rather, the concept extends to all functionally equivalent structures, methods and uses, such as are within the scope of the appended claims. Those skilled in the art, having the benefit of the teachings of this specification, may affect numerous modifications thereto and changes may be made without departing from the scope and spirit of the concept in its aspects. For example, the cover 10 could be deployed over a conventional non-electric motor vehicle, the component(s) or the entirety of which has caught fire, such as a car, truck, etc.
