SOS Window System and Control Method Thereof {SOS Window System and Controll Method Thereof}

The present invention relates to an SOS window system for forcibly opening a window when a vehicle accident occurs and a passenger cannot evacuate through a door, and a method for controlling the same.

In general, express buses get on and off passengers through swing doors that open in the front, and glass windows are adopted for reasons such as safety, noise, and fuel efficiency. However, if an accident occurs and the only entrance is blocked by an obstacle or is broken and cannot be opened, you must destroy the window and escape through the window.

Existing emergency escape systems use a method in which a passenger directly breaks a window using an emergency escape hammer. However, the location and use of safety devices and emergency response tips are not being communicated to passengers, and safety equipment in express buses is not properly equipped, so there are concerns about passenger safety. That is, in the event of an accident, there is a problem in that many passengers cannot quickly escape when an accident occurs on the bus due to the adoption of a glass window and a front swing door and no emergency door.

Furthermore, in the case of the current emergency escape system of express buses, it is not easy to break the glass by tinting the window, and the method of escaping by breaking the window can rather threaten the safety of passengers in an emergency situation.

Therefore, a system is being developed that enables passengers to quickly escape by automatically destroying the windows without manually breaking the windows with an emergency hammer in an emergency situation.

As shown in these drawings, an embodiment of the SOS window system of the present invention is for automatically destroying a window 3 of a vehicle 1 without using a hammer, and the front door 2 cannot be used. It is an invention that is particularly needed in the case. The present invention includes a control unit 10 that controls a system and a drive unit 110 driven according to a driving command of the control unit 10 . The drive unit 110 includes an impact unit 120 that strikes the window 3 of the vehicle 1 .

The control unit 10 is configured to generate a driving command using an algorithm when the operation of the SOS switch 18 or an accident is recognized, and includes a micro control unit (MCU), a battery 11 for supplying power to the system, and a battery 11 ) to operate, watchdog (13) to prevent MCU failure, IGN Key (14) to check the operation status of the ignition key, impact detected by vehicle (1) front and side collision sensors A collision sensor 15 (ACU, Airbag Control Unit) that receives the information and determines whether the vehicle 1 collides, a speed sensor 16 that detects the speed of the vehicle 1, and a deformation that measures the degree of deformation of the front door It includes a measurement sensor 17 and an SOS switch 18 forcibly operating the drive unit 110 in case of an emergency.

The MCU generates a driving command through an algorithm using the collision sensor 15, the speed sensor 16, and the deformation measurement sensor 17. The control method of the SOS window system of the present invention together with the algorithm will be described using FIG. 9 . First, it is determined whether it is in the automatic mode (S1), and if it is not in the automatic mode, the SOS switch 18 is operated (S2) to operate the driving unit 110 (S5). In the case of the automatic mode, a collision is detected by a collision sensor, and it is determined whether the speed variation is higher than a reference value (S3). Here, the reference value can be set to about 80%. If a collision is detected and it is not determined that the speed is rapidly reduced, the sensor continues monitoring in the automatic mode again, and when a collision and a sudden decrease in speed are detected, the strain of the front door (2) is measured by the deformation sensor (17) , It is determined whether the deformation exceeds the standard value through the MUC (S4). If the strain rate is less than the reference value, the monitoring operation of the sensor continues again in the automatic mode state, and if the strain rate is greater than the reference value, the window 3 is destroyed by operating the driver 110 (S5).

Referring to the deformation measurement sensor 17 in more detail with reference to FIG. 2 , the deformation measurement sensor 17 is attached along the surface of the front door 2 and can be formed to deform together when the front door 2 is deformed. . Furthermore, a conductor extending in the plane direction of the front door 2 may be included. Accordingly, when the front door 2 is deformed, the conductors are also stretched or contracted, resulting in a change in the total resistance of the conductors. Therefore, the strain of the front door 2 can be calculated inversely by measuring the resistance.

Hereinafter, the driving unit 110 will be described with reference to FIGS. 3 to 7 . FIG. 3 shows a general state in which an accident does not occur, and FIG. 4 shows a state when the window 3 is destroyed in the event of an accident.

The impact unit 120 rotates while being connected to the drive unit 110, and includes an impact body 121 including a protruding portion toward the glass window 3 in a rotated state, and further at the corner of the impact unit 121. It may include an impact blade 122 that protrudes and is formed sharp and sharp. A plurality of impact blades 122 may be formed spaced apart.

As shown in FIG. 5 , the shock body 121 is rotated by the driving unit 110, and the driving unit 110 is fixed to and controlled by the vehicle body. The drive unit 110 includes a rotation unit 115 installed on the vehicle body by a rotation shaft 118 to rotate together with the impact unit 120, and a spring having one end fixed to one side of the rotation unit 115 and the other end fixed to the vehicle body. It includes a spring 117 fixed to the support part 111, a clasp 113 opened and closed by driving a motor 112, and a moving part 114 whose straight movement is limited by the clasp 113. The clasp 113 is inserted into the clasp fixing groove 114a formed in the moving part 114 to limit the movement of the moving part 114. In addition, a fixing protrusion 116 may be protruded from the rotating part 115 at a position spaced apart from the center of the rotating shaft 118, and the fixing protrusion 116 is inserted into the rotating fixing groove 114b formed in the moving part 114. Thus, the rotation unit 115 and the moving unit 114 may be interlocked.

Therefore, in a general situation where an accident does not occur as shown in FIG. 6, the spring 117 is extended to pull the rotating part 115, and the fixing protrusion 116 of the rotating part 115 is the rotation fixing groove of the moving part 114 ( 114b), but the clasp 113 is inserted into the clasp fixing groove 114a of the moving part 114, so that the moving part 114 is restricted. And, as shown in FIG. 7, in a situation where an accident occurs and the window 3 is destroyed, when the clamp is separated from the moving part 114 by driving the motor 112, the moving part 114 remains engaged with the fixing protrusion 116. The spring 117 is moved in the direction in which the spring 117 is compressed by the restoring force of the spring 117, and when the moving part 114 is sufficiently moved, the fixing protrusion 116 is separated from the rotation fixing groove 114b and the rotating part 115 can rotate For this operation, the rotating part 115 is fixed at a position where the angle between the rotating shaft 118, one end of the spring 117, and the other end of the spring 117 is smaller than 180 degrees, and the rotating part 115 is rotated. The installation position of the spring 117 can be adjusted so that the angle between the rotating shaft 118, one end of the spring 117, and the other end of the spring 117 is 180 degrees.
