DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to facilitate a person skilled in the art to easily carry out the present invention.

Hereinafter, in FIG. 2, the transverse direction is referred to as "width direction", the longitudinal direction as "longitudinal direction", and the direction perpendicular to the paper as "axial direction".

As shown in FIGS. 2 to 5, the emergency opening / closing apparatus for a train according to an embodiment of the present invention includes a emergency lever 100 disposed at a position adjacent to a railway vehicle door, An actuator 200 for providing a driving force to the protruding rod 210, and a door control unit 700.

 2, the emergency lever 100 includes a plate-shaped cover 110 disposed at a position adjacent to a railway vehicle door, a manual lever 130 provided on the cover 110, a cover 110, And an emergency handle (150) provided on the handle (130) and spaced apart from the manual lever (130).

The door of the railway car can be manually opened by operating the manual lever 130. [

The emergency handle 150 rotates the axially extending handle axis R by a predetermined distance on the rotation axis so that the manual lever 130 can be operated or disabled.

For example, when the emergency handle 150 is located at the first position A1, the manual lever 130 is in an inoperable state. Even if the manual lever 130 is operated by applying an external force to the manual lever 130, The door of the door can not be opened manually.

When the emergency handle 150 is positioned at the second position A2, the manual lever 130 is in an operable state and the manual lever 130 is operated to manually open the door of the railway vehicle There is a number.

4, between the emergency handle 150 and the manual lever 130, the rotary motion of the emergency handle 150 is switched to a rectilinear motion by being connected to the emergency handle 150, (Not shown) to a locked state or to an unlocked state.

One side of the unlocking rod 300 is connected to the emergency handle 150 and the other side is connected to the side of the manual lever 130.

Therefore, when the emergency handle 150 is located at the first position A1, the other side of the unlocking rod 300 is pressed so that the manual lever 130 is not operated, so that the door of the railway vehicle is manually opened .

When the emergency handle 150 is rotated to the second position A2, the unlocking rod 300 is moved toward the emergency handle 150 in accordance with the rotation of the emergency handle 150, The door of the railway vehicle can be manually opened.

The mechanical operation between the emergency handle 150, the manual lever 130, and the unlocking rod 300 is a known matter, so a detailed description is omitted.

The protruding and detaching rod 210 is disposed within a rotation range around the axis of rotation which is an operating range of the emergency handle 150. The protruding and detaching rod 210 is disposed between the first position A1 and the second position A2, 110 in the axial direction so as to be movable forward and rearward.

The emergency handler 150 must be moved from the first position A1 to the second position A2 when the emergent rod 210 protrudes forward, RTI ID = 0.0 > A1, < / RTI >

The actuator 200 is axially provided on one side of the emergency handle 150 from the inside of the cover 110 and the protruding and retracting rod 210 is provided at an end thereof.

The actuator 200 may be composed of any one of an electric actuator that provides an actuating force by driving the motor, a stretching cylinder that provides an actuating force by the pressure of the fluid or gas, and a solenoid that provides an actuating force by a magnetic force.

In the present invention, it is preferable to use a solenoid as the actuator 200.

Therefore, when the actuator 200 is driven, the protruding and retracting rod 210 protrudes forward by a driving force. When the actuator 200 is driven again, the protruding and retracting rod 210 moves backward and returns to the win position.

The door control unit 700 includes a vehicle speed comparison module 710 for comparing the vehicle speed of the railway vehicle through a separate vehicle speed sensing unit 500 with a preset vehicle speed, And an actuator control module 750 for outputting a signal for driving the actuator 200.

The vehicle speed sensing unit 500 may be a rotation sensor that senses the rotation of the axle or wheel of the railway vehicle or a displacement sensor that senses the speed of the railway vehicle.

In addition to such a sensor system, a GPS signal may be received to detect a change in the position of a railway vehicle, or various types of speed detection means may be provided.

The train emergency door opening / closing apparatus constructed as described above operates as follows.

6, the emergency handle 150 is located at the first position A1 and the protruding rod 210 is located at the inner side of the cover 110 And the emergency handle 150 is in a rotatable state at the second position A2 so that the door of the railway car can be manually opened.

Then, when the railway vehicle starts, the speed of the railway vehicle sensed through the vehicle speed sensing unit 500 is transmitted to the vehicle speed comparison module 710 of the door control unit 700, and the predetermined speed (for example, 5 km per hour) And when the speed of the railway vehicle exceeds the preset speed, the actuator control module 750 outputs a control signal for driving the actuator 200. [

7, the protruding rod 210, which receives the driving force of the actuator 200, is protruded forward from the outside of the cover 110, Thereby preventing the emergency handle 150 from rotating.

Accordingly, since the emergency handle 150 is fixed, even if an external force is applied to the manual lever 130, the manual lever 130 is kept in a locked state, so that the door of the railway vehicle is not manually opened.

Then, when the speed is decreased to stop the railway vehicle and the speed is determined to be lower than a predetermined speed through the door control unit 700, the controller 200 outputs a control signal to the actuator 200.

The actuator 200 is driven by receiving a control signal and the protruding rod 210 having received the driving force of the actuator 200 is moved to the rear of the interior of the cover 110, So that the rotation can be performed.

Therefore, the manual lever 130, which is rotated by the rotation of the emergency handle 150, is in the unlocked state, and the door of the railway vehicle is manually opened.

As described above, according to the present invention, when the railway vehicle is in operation, that is, when the predetermined speed is exceeded, the manual lever 130 is prevented from being actuated, and the door of the railway vehicle is prevented from being opened manually, And when the railway vehicle is stopped due to a failure or an accident, that is, when the railway vehicle is below a preset speed, the manual lever 130 is operated so that the door of the railway vehicle can be manually opened so that the driver can quickly escape.

In addition, the opening of the door at the time of train operation can be fundamentally blocked by a simple method of installing the actuator on the rear side of the cover of the existing emergency handle, without changing the structure of the existing emergency handle.

8, the actuator 200a may be disposed in the width direction away from the emergency handle 150 at the inside of the cover 110. As shown in FIG.

At this time, the protruding and detaching rod 210a of the actuator 200a moves in the width direction toward the unlocking rod 300.

Therefore, when the speed of the railway vehicle exceeds the predetermined speed, the protruding and retracting rod 210a protrudes and is brought into close contact with the side surface of the unlocking rod 300 by driving the actuator 200a as shown in Fig. 9, The movement of the unlocking rod 300 is stopped.

Accordingly, the emergency handle 150 can not rotate and is fixed, so that even if an external force is applied to the manual lever 130, the manual lever 130 is kept in a locked state, so that the door of the railway vehicle is not manually opened.

When the speed of the railway vehicle is determined to be equal to or lower than a preset speed, the protruding rod 210a is returned to its original state by being driven by the actuator 200a to be separated from the unlocking rod 300, The emergency handle 150 is allowed to rotate, and the manual lever 130 is unlocked so that the door of the railway vehicle can be manually opened.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, It will be readily apparent that various substitutions, modifications, and alterations can be made herein.
