Description

Technology Field

[0001] 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. Background Technology

[0002] Automobiles are a means of land transportation.

[0003] 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.

[0004] 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.

[0005] For this reason, electric vehicles have recently been attracting attention.

[0006] 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.

[0007] However, electric vehicles had a problem where it was difficult to escape in the event of an accident.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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. Prior art literature

[0012] Republic of Korea Published Patent No. 10-2024-0058238 The problem to be solved

[0013] The present invention is proposed to resolve the problems of the prior art as described above, and aims to provide an emergency escape system for electric vehicles that can reduce casualties caused by accidents by enabling 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.

[0014] Meanwhile, the present invention is the result of research conducted under the Phase 3 Industry-Academic Cooperation Leading University Development Project (LINC 3.0), which was funded by the Ministry of Education and the National Research Foundation of Korea. means of solving the problem

[0015] To achieve the above objective, the present invention,

[0016] An emergency escape system for an electric vehicle is proposed, 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, with 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.

[0017] The door on which the above airbag module is installed may be the driver's door of the electric vehicle.

[0018] The explosive charge of the above explosive member can be fixed to the welded portion of the hinge and the fastening portion of the fastening member.

[0019] The above switch module initiates the operation of the airbag module and the detonator, and initiates the operation of the detonator after a certain period of time has elapsed since the initiation of the operation of the airbag module.

[0020] The above switch module can be circuitously connected to a detection member that detects an accident of the electric vehicle. Effects of the invention

[0021] The emergency escape system for an electric vehicle according to the present invention includes an explosive member mounted on the hinge of one of the doors of the electric vehicle. When power supply through the main battery is impossible due to an accident such as a fire, and thus the door cannot be opened by motor drive, the door hinge is destroyed by the explosion of the explosive member, thereby allowing the door to be forcibly opened. As a result, passengers can escape through the opened door, thereby reducing casualties caused by the accident. Brief explanation of the drawing

[0022] 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. Specific details for implementing the invention

[0023] The present invention will be described in detail below with reference to the attached drawings.

[0025] 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).

[0026] 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).

[0027] 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.

[0028] 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.

[0029] 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.

[0030] The explosive member (20) of the present invention is mounted on the hinge (112) of the door (110).

[0031] 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.

[0032] At this time, the explosive member (20) can be exploded by igniting the gunpowder with the detonator (21) by connecting the detonator (21) to the gunpowder (not shown in the drawing).

[0033] And the explosives of the explosive member (20) are fixed particularly to the welded part of the hinge (112) and the fastening part of the fastening member, so that the welded part of the hinge (112) and the fastening part of the fastening member are destroyed by the explosion of the explosive member (20), and the door (110) is separated from the vehicle body (not shown in the drawing), thereby allowing the door (110) to be forcibly opened.

[0034] The switch module (30) of the present invention is placed inside the electric vehicle (100).

[0035] Therefore, in the event of an accident involving an electric vehicle (100), it may be easy to operate the switch module (30) by a passenger inside the electric vehicle (100).

[0036] At this time, the switch module (30) can initiate the operation of the airbag module (10) and the detonator (21), thereby enabling the deployment of the airbag (11) and the explosion of the explosive member (20).

[0037] Meanwhile, the switch module (30) initiates the operation of the airbag module (10) and the detonator (21), but initiates the operation of the detonator (21) after a certain amount of time has elapsed since the operation of the airbag module (10), so that the explosion of the explosive member (20) can occur while the glass window of the door (110) is broken, and as the explosion pressure of the explosive member (20) is discharged to the outside of the vehicle body through the broken glass window, user injury caused by the explosion pressure of the explosive member (20) can be suppressed.

[0038] Additionally, the switch module (30) can be circuitously connected to a detection member (31) that detects an accident of the electric vehicle (100).

[0039] Therefore, the operation of the switch module (30) can be automatically performed by the signal of the detection member (31) that detects the occurrence of an accident in the electric vehicle (100), thereby reducing the inconvenience associated with operating the switch module (30).

[0040] Here, the sensing member (31) may be of any ordinary structure and method as long as it is capable of detecting the occurrence of an accident of the electric vehicle (100) through at least one of heat detection, flame detection, and flood detection, so a detailed description of the sensing member (31) is omitted.

[0041] The auxiliary battery (40) of the present invention is provided separately from the main battery (not shown in the drawing) of the electric vehicle (100).

[0042] Therefore, power can be supplied through the auxiliary battery (40) when power supply through the main battery of the electric vehicle (100) is not possible.

[0043] At this time, the auxiliary battery (40) supplies power to the airbag module (10), detonator (21), and switch module (30), so that the operation of the airbag module (10), detonator (21), and switch module (30) can be achieved by the power supply from the auxiliary battery (40).

[0044] As long as such auxiliary battery (40) can supply power to the airbag module (10), detonator (21), and switch module (30) when power supply through the main battery of the electric vehicle (100) is not possible, it may be of any ordinary structure and method, so a detailed description of the auxiliary battery (40) is omitted.

[0046] The emergency escape of a passenger through the emergency escape system (A) for an electric vehicle according to the present invention is described in detail as follows.

[0047] In the present invention, the explosive member (20) is mounted on the hinge (112) of one door (110) provided in the electric vehicle (100).

[0048] At this time, since a detonator (21) is connected to the gunpowder of the explosive member (20), the explosion of the explosive member (20) can be achieved by igniting the gunpowder through the detonator (21).

[0049] Therefore, in the event of an accident involving an electric vehicle (100), particularly when power supply through the main battery is not possible and the door (110) cannot be opened by motor drive, the door (110) can be forcibly opened by destroying the door (110) hinge (112) through the operation of the switch module (30) placed inside the electric vehicle (100) by detonating the explosive member (20), thereby allowing the passenger to escape in an emergency through the opening of the door (110).

[0050] At this time, power is supplied to the switch module (30) and the detonator (21) by an auxiliary battery (40) provided separately from the main battery of the electric vehicle (100), so the switch module (30) and the detonator (21) can operate smoothly even when power supply through the main battery is not possible.

[0051] However, if the hinge (112) of the door (110) is not destroyed by the explosion of the explosive member (20), the door (110) cannot be forcibly opened, so emergency escape may be difficult.

[0052] However, in the present invention, the explosives of the explosive member (20) are fixed to the vulnerable parts of the door (110) hinge (112), specifically the welded part of the hinge (112) and the fastening part of the fastening member, as shown in FIG. 3. Since the door (110) hinge (112) can be destroyed relatively easily by the explosion of the explosive member (20), the door (110) can be forcibly opened smoothly, making it easy to escape in an emergency.

[0053] Meanwhile, the emergency escape system (A) for an electric vehicle according to the present invention can suppress passenger injury during the explosion of the explosive member (20).

[0054] That is, the present invention includes an airbag module (10) mounted on one door (110) of an electric vehicle (100), and as shown in FIG. 2, the airbag (11) of the airbag module (10) is deployed by operating a switch module (30) placed inside the electric vehicle (100), and as a result, the glass window of the door (110) is pushed outward and can be broken. After the glass window of the door (110) is broken by the deployment of the airbag (11) of the airbag module (10), the explosive member (20) explodes, and the explosive pressure can be discharged outward through the broken glass window, thereby suppressing user injury caused by the explosive pressure.

[0055] At this time, the switch module (30) initiates the operation of the airbag module (10) and the detonator (21), but initiates the operation of the detonator (21) after a certain amount of time has elapsed since the operation of the airbag module (10) began, so that the deployment of the airbag (11) of the airbag module (10) and the explosion of the explosive member (20) can be carried out sequentially by the operation of the switch module (30).

[0056] Here, power is supplied to the airbag module (10) by an auxiliary battery (40) provided separately from the main battery of the electric vehicle (100), so the airbag module (10) can operate smoothly even when power supply through the main battery is not possible.

[0057] In addition, the emergency escape system (A) for an electric vehicle according to the present invention can reduce the inconvenience associated with operating the switch module (30).

[0058] That is, the switch module (30) of the present invention can be circuitously connected to a detection member (31) that detects an accident of an electric vehicle (100). Since the operation of the switch module (30) can be automatically performed according to the signal of the detection member (31) when an accident occurs in the electric vehicle (100), the inconvenience of operating the switch module (30) can be reduced, allowing for a more rapid emergency escape.

[0060] The present invention, as described above, is not limited to the embodiments described above and may be modified within the scope that does not deviate from the essence of the invention claimed in the claims, and such modifications fall within the scope of protection of the present invention as defined by the claims below.
