Fire extinguisher cover for electric vehicle

Abstract

Disclosed is a fire extinguisher cover for covering over a motor vehicle, the battery of which has caught fire. The cover comprises a sheet for covering over the vehicle, the sheet comprising an opening disposed thereon, and a casing assembly comprising a plurality of spaced apart casings and a drawstring running through the plurality of 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, and the fire-extinguishing fluid is run through the at least one opening to be fill up between the vehicle and the sheet resulting in said fluid reaching the battery for extinguishing the fire emanating therefrom.

DETAILED DESCRIPTION OF EMBODIMENTS

(14) 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.

(15) 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.

(16) 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.

(17) Still referring to FIG. 1, the casing 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 sheets 12, elongate transverse casings disposed closer to the transverse edges of the sheet 12 and oblique corner casings disposed between the longitudinal and transverse casings. The open extremity of each casing 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.

(18) 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.

(19) 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.

(20) 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.
