Abstract

The present invention relates to an emergency escape system for an electric vehicle, characterized by comprising: an airbag module mounted on one of the doors of the electric vehicle, which pushes the glass window of the door outward and breaks it as the airbag deploys; an explosive member mounted on the hinge of the door, which has a detonator connected to a gunpowder; a switch module disposed inside the electric vehicle, which initiates the operation of the airbag module and the detonator; and an auxiliary battery provided separately from the main battery of the electric vehicle, which supplies power to the airbag module, the detonator, and the switch module.

Description

Emergency escape system for electric vehicles The present invention relates to an emergency escape system, and more specifically, to an emergency escape system for an electric vehicle that enables the door hinge to be destroyed when power supply through the main battery is impossible due to an accident such as a fire, thereby allowing the passenger to escape through the door opened by the destruction of the hinge, thereby reducing casualties caused by the accident. Automobiles are a means of land transportation. Automobiles constitute the main means of land transportation, as they not only have the advantage of being able to move at relatively high speeds but also carry a relatively large number of passengers and a relatively large amount of cargo. However, in the case of ordinary automobiles, since they are driven by internal combustion engines, there was a problem of causing air pollution due to exhaust gases. For this reason, electric vehicles have recently been attracting attention. Since electric vehicles are driven by motors powered by batteries, they can prevent air pollution by eliminating exhaust emissions, reduce driver fatigue due to minimal noise during driving, and lower maintenance costs by reducing the number of parts; consequently, their adoption is rapidly increasing as they replace conventional automobiles using internal combustion engines. However, electric vehicles had a problem where it was difficult to escape in the event of an accident. In other words, electric vehicles face a problem where casualties occur because the power supply from the battery is cut off in the event of an accident such as a fire or flood, rendering the motor responsible for opening and closing the doors unable to operate and preventing passengers from escaping. For this reason, mechanical opening and closing devices are provided on the doors of electric vehicles; however, most conventional mechanical opening and closing devices installed on electric vehicle doors are hidden inside the door's control panel for aesthetic purposes, which presents a problem in that they are not easy to operate in emergency situations. In addition, various 'escape systems' as disclosed in Korean Public Patent No. 10-2024-0058238, etc., are being applied to electric vehicles; however, most of the conventional escape devices applied to electric vehicles have complex structures, making installation difficult and operation particularly challenging in emergency situations. For the reasons mentioned above, attempts are being made in this field to develop emergency escape systems for electric vehicles that not only facilitate easy installation and operation through a simple structure but also enable passengers to safely and quickly escape in the event of an accident; however, satisfactory results have not yet been achieved. FIG. 1 is a schematic diagram of an emergency escape system for an electric vehicle according to the present invention. FIG. 2 is an example diagram showing the deployment of an airbag module in an emergency escape system for an electric vehicle according to the present invention. FIG. 3 is an example diagram showing the configuration in which an explosive member is positioned at the door hinge in an emergency escape system for an electric vehicle according to the present invention. The present invention will be described in detail below with reference to the attached drawings. As illustrated in FIG. 1, the emergency escape system (A) for an electric vehicle according to the present invention includes an airbag module (10); an explosive member (20); a switch module (30); and an auxiliary battery (40). The airbag module (10) of the present invention is mounted on one door (110) of an electric vehicle (100), more specifically on the driver's door (110). Therefore, as the airbag (11) of the airbag module (10) deploys, not only can the driver's body in the driver's seat be protected, but the glass window (not shown in the drawing) of the door (110) can also be pushed outward and broken. At this time, the airbag module (10) is positioned between the panel (111) on the inner side of the door (110) and the glass window, so that as the airbag (11) deploys, the glass window of the door (110) can be pressurized, and thereby the glass window can be pushed outward and broken. As long as such an airbag module (10) can break the glass window of any door (110) of the electric vehicle (100) through the deployment of the airbag (11), it may be of any ordinary structure and method, so a detailed description of the airbag module (10) is omitted. The explosive member (20) of the present invention is mounted on the hinge (112) of the door (110). Therefore, as the explosive member (20) explodes at the hinge (112) of the door (110), the hinge (112) may be destroyed, thereby allowing the door (110) to be forcibly opened. At this time, the explosive member (20) can be exploded by igniting the gunpowder with the detonator (21) by connecting the d
