Embodiments of the inventive concept described herein relate to a train hatch module for hiding a coupling of a train from the outside of the train or exposing the coupling of the train to the outside of the train.
A high-speed train is a railway vehicle that travels at high speed. The front part of the high-speed train usually has an aerodynamic shape such as a pointed shape in consideration of air resistance. This is because the air resistance of the high-speed train traveling at high speed is increased in proportion to the square of the speed of the high-speed train and impact due to an air pressure difference is further increased when the high-speed train enters a tunnel.
Couplings are components connecting trains on railroads. The couplings are provided for all railway vehicles, regardless of whether the railway vehicles are locomotives or passenger cars. The couplings include a knuckle coupling, a tight-lock coupling, a Scharfenberg coupling, and the like. Meanwhile, regardless of the types, the above-described couplings are not all shaped to minimize air resistance. Accordingly, high-speed trains include hatches capable of hiding couplings provided at the front of the high-speed trains.
Embodiments of the inventive concept provide a train hatch module for connecting a hatch cover to a hatch body of a train while stably supporting the hatch cover that allows a coupling to be exposed to the outside of the train only when the train needs to be connected with another train.
Embodiments of the inventive concept provide a train hatch module for enabling safe operation or safe maintenance of a train by stably preventing movement of a hatch cover when the hatch cover at the front of the train is completely opened or closed.
Embodiments of the inventive concept provide a train hatch module for preventing deterioration in the durability of parts of a high-speed train by stably connecting an actuator for providing power to operate a hatch cover at the front of the train to a hatch body of the train.
Embodiments of the inventive concept provide a train hatch module for simply and safely separating a hatch cover at the front of a train from the train for reasons such as maintenance.

When the train hatch module is in an operating mode, the locking module may be located at a second movement through-hole end that is an end of the lower movement through-hole that faces in a direction toward the center of the train.
The rotation support may include a locking plate member provided at the lower end of the rotation support, and the locking module, when located at the first movement through-hole end, may make contact with the locking plate member to make it impossible for the rotation support to rotate.

Referring to
The train hatch module 1 may be provided at the front of a lower part of a train and may expose a coupling of the train to the outside or may hide the coupling inside.
Couplings of trains may be components capable of connecting the trains. The couplings provided at the lower ends of the trains may be connected with each other to connect the trains. However, since the configurations of the couplings are often not aerodynamic, the trains travelling at high speeds may exhibit poor driving performance when the couplings protrude from the ends of the trains. Accordingly, in the case of the first railroad cars and the last railroad cars of the high-speed trains travelling at high speeds, the couplings may be hidden at ordinary time and may preferably be exposed to the outside only when the high-speed trains need to be connected with other trains.
The hatch cover 100 may be provided at the front of the lower part of the train. The hatch cover 100 may be opened and closed while rotating in the lateral direction. When the hatch cover 100 is opened, the coupling of the train may be exposed to the outside.
The hatch body 900 may be connected to the main body of the train so as to be located at the front of the train. A component that supports the hatch cover 100 and a component that operates the train hatch module 1 may be provided in the hatch body 900.
Referring to
The rotation support 200 may support the hatch cover 100 while making contact with the inner surface of the hatch cover 100. The rotation support 200 may serve as a frame that supports the hatch cover 100 and may be formed of a metallic material. However, the rotation support 200 is not necessarily limited to being formed of metal.
The rotation support 200 may rotate about the upper rotation shaft 711 connected to the upper end of the rotation support 200 and the lower rotation shaft 511 connected to the lower end of the rotation support 200. The rotation support 200 may be connected to the upper rotation center member 710 in such a manner that the upper end of the rotation support 200 is connected to the upper rotation shaft 711 and may be connected to the lower rotation center member 510 in such a manner that the lower end of the rotation support 200 is connected to the lower rotation shaft 511.
Referring to
The lower base 500 may include the lower rotation center member 510, a first locking-plate fixing member 520, and a second locking-plate fixing member 530.
The lower rotation center member 510 may be located at the upper end of the lower base 500 and may be provided with the lower rotation shaft 511 about which the rotation support 200 rotates.
The lower rotation shaft 511 may be located at the upper end of the lower base 500 and may be a central axis about which the rotation support 200 rotates. The lower rotation shaft 511 may face in the up-down direction of the train. That is, when the rotation support 200 rotates about the lower rotation shaft 511, this may mean that when viewed in the up-down direction of the train, the rotation support 200 moves in the lateral direction of the train while rotating about the lower rotation shaft 511.
The train hatch module 1 may include the upper base 700. The upper base 700 may be connected to the hatch body 900 of the train and may be located above the coupling. The upper base 700 may be formed of a plate. Among the components of the train hatch module 1, components provided at the upper end of the train hatch module 1 may be provided on the upper base 700.
The upper base 700 may include the upper rotation center member 710, the horizontal actuator module 720, and a sliding actuator 730.
The horizontal actuator module 720 may be provided at the lower end of the upper base 700 and may face in the front-rear direction of the train.
The upper rotation center member 710 may be located at the lower end of the upper base 700 and may be provided with the upper rotation shaft 711.
The upper rotation shaft 711 may be located at the lower end of the upper base 700 and may be a central axis about which the rotation support 200 rotates. The upper rotation shaft 711 may face in the up-down direction of the train. That is, when the rotation support 200 rotates about the upper rotation shaft 711, this may mean that when viewed in the up-down direction of the train, the rotation support 200 moves in the lateral direction of the train while rotating about the upper rotation shaft 711.
Referring to
The sliding actuator 730 may be provided at the lower end of the upper base 700 and may move in the front or rear direction of the train along the horizontal actuator module 720.
The sliding actuator 730 may provide a driving force required to open and close the hatch cover 100 while moving along the horizontal actuator module 720. Specifically, the sliding actuator 730 may be provided at the lower end of the upper base 700 and may provide a driving force required to rotate the rotation support 200 while moving in the front or rear direction of the train along the horizontal actuator module 720. The driving force of the sliding actuator 730 may be a force generated by the sliding actuator 730 itself or a force transmitted to the sliding actuator 730 by the horizontal actuator module 720.
The train hatch module 1 may further include the connecting rod 800. The connecting rod 800 may be connected at one end thereof to the sliding actuator 730 and may be connected at an opposite end thereof to the upper end of the rotation support 200. The connecting rod 800 may connect the sliding actuator 730 and the rotation support 200. The connecting rod 800 may be a rod formed of a metallic material. However, the material of the connecting rod 800 is not limited thereto.
The connecting rod 800 may directly transmit the force transmitted from the sliding actuator 730 to the rotation support 200. The connecting rod 800 may transmit the force transmitted from the sliding actuator 730 to the rotation support 200 while the sliding actuator 730 moves to the rear of the train. The rotation support 200 may be rotated about the upper rotation shaft 711 and the lower rotation shaft 511 by the force transmitted from the connecting rod 800.
However, the connecting rod 800 is not necessarily limited to transmitting the force to the rotation support 200. For example, the connecting rod 800 may be connected at the one end thereof to the sliding actuator 730 and may be directly connected at the opposite end thereof to the hatch cover 100. The connecting rod 800 may directly transmit the force transmitted from the sliding actuator 730 to the hatch cover 100.
The hatch cover 100 may be rotated about the upper rotation shaft 711 and the lower rotation shaft 511 by the force applied to the hatch cover 100 from the rotation support 200, the first protruding support 310, and the second protruding support 320. That is, the connecting rod 800 may transmit the force transmitted from the sliding actuator 730 to the rotation support 200 while the sliding actuator 730 moves to the rear of the train, thereby enabling the hatch cover 100 connected to the rotation support 200 to be opened while rotating.
The sliding actuator 730 of the horizontal actuator module 720 may move in the front or rear direction of the horizontal actuator module 720, and the connecting rod 800 may be completely fixed to the sliding actuator 730 and may move in the same direction as the sliding actuator 730. Since the connecting rod 800 is connected to the rotation support 200 that performs a rotational motion, if the horizontal actuator module 720 is fixed without moving on the upper base 700, operation of the sliding actuator 730, movement of the connecting rod 800, and rotation of the rotation support 200 may not be possible.
Referring to
The horizontal actuator module 720 may rotate about the horizontal actuator rotation shaft 701. Specifically, when the extension direction of the connecting rod 800 is changed as the rotation support 200 rotates, the horizontal actuator module 720 may rotate about the horizontal actuator rotation shaft 701 to face in the same direction as the extension direction of the connecting rod 800.
The horizontal actuator rotation shaft 701 may be provided between the horizontal actuator module 720 and the upper base 700 and may connect the horizontal actuator module 720 to the upper base 700. That is, the horizontal actuator module 720 may be connected to the upper base 700 by the horizontal actuator rotation shaft 701 so as to be suspended from the upper base 700.
However, when the horizontal actuator module 720 is connected to the upper base 700 only by the horizontal actuator rotation shaft 701, the horizontal actuator module 720 may be suspended from the upper base 700 only by one component so that the load of the horizontal actuator module 720 may be excessively concentrated on a partial area, which may lead to deterioration in the durability of parts. Therefore, it may not be preferable as one configuration of the train traveling at high speed to connect the horizontal actuator module 720 to the upper base 700 only by the horizontal actuator rotation shaft 701.
The upper base 700 may have an upper movement through-hole 702 formed therein. The upper movement through-hole 702 may be a through-hole penetrating from the top to the bottom of the upper base 700. The upper movement through-hole 702 may be formed such that a shaft having a circular cross-section moves in the extension direction of the upper movement through-hole 702. That is, the width of the upper movement through-hole 702 may be equal to the width of the shaft passing through the upper movement through-hole 702, and the length of the upper movement through-hole 702 may be greater than or equal to the width of the shaft passing through the upper movement through-hole 702.
The horizontal actuator module 720 may include, at the upper end thereof, a horizontal actuator movement shaft 721 configured to pass through the upper movement through-hole 702. The horizontal actuator movement shaft 721 may move in the lateral direction of the train along the upper movement through-hole 702.
Since the horizontal actuator module 720 is connected to the upper base 700 by the horizontal actuator rotation shaft 701 and the horizontal actuator movement shaft 721, the load of the horizontal actuator module 720 may be distributed, and deterioration in the durability of parts may be prevented, as compared with when the horizontal actuator module 720 is suspended from the upper base 700 only by one component.
Referring to
The lower base 500 may have a lower movement through-hole 501 formed therein. The lower movement through-hole 501 may be a through-hole penetrating from the top to the bottom of the lower base 500. The lower movement through-hole 501 may be formed such that a shaft having a circular cross-section moves in the extension direction of the lower movement through-hole 501. That is, the width of the lower movement through-hole 501 may be equal to the width of the shaft passing through the lower movement through-hole 501, and the length of the lower movement through-hole 501 may be greater than or equal to the width of the shaft passing through the lower movement through-hole 501.
The train hatch module 1 may further include the locking module 600. The locking module 600 may prevent movement of the rotation support 200 to maintain the hatch cover 100 in a completely open state or a completely closed state.
The locking module 600 may have the shape of a shaft. However, the shape of the locking module 600 is not limited thereto. The locking module 600 may pass through the lower movement through-hole 501 and may protrude upward from the lower base 500.
The locking module 600 may move in the lateral direction of the train along the lower movement through-hole 501. The locking module 600 may be moved by power transmitted from a separately connected actuator. A locking mode may correspond to a state of the train hatch module 1 in which the hatch cover 100 does not move as when the hatch cover 100 is completely opened or closed. An operating mode may correspond to a state of the train hatch module 1 in which the sliding actuator 730 is in operation and the rotation support 200 and the hatch cover 100 are on the move.
When the train hatch module 1 is in the locking mode, the locking module 600 may be located at a first movement through-hole end 502 of the lower movement through-hole 501. The first movement through-hole end 502 may be an end of the lower movement through-hole 501 that faces in the lateral direction of the train. The locking module 600, when located at the first movement through-hole end 502, may make contact with the locking plate member 220 to make it impossible for the rotation support 200 to rotate.
When the train hatch module 1 is in the operating mode, the locking module 600 may be located at a second movement through-hole end 503 of the lower movement through-hole 501. The second movement through-hole end 503 may be an end of the lower movement through-hole 501 that faces in a direction toward the center of the train.
Referring to
When the locking module 600 is located at the first movement through-hole end 502 in the state in which the hatch cover 100 is completely closed, the first locking-plate end member 221 may make contact with the locking module 600 to make it impossible for the rotation support 220 to move toward the locking module.
The lower base 500 may include the first locking-plate fixing member 520 protruding upward from the front area of the lower base 500. When the locking module 600 is located at the first movement through-hole end 502 in the state in which the hatch cover 100 is completely closed, the first locking-plate fixing member 520 may make contact with the locking plate member 220 to make it impossible for the rotation support 200 to move.
That is, when the locking module 600 is located at the first movement through-hole end 502 in the state in which the hatch cover 100 is completely closed, the movement of the rotation support 200 may be completely prevented by the locking module 600 and the first locking-plate fixing member 520 that make contact with the locking plate member 220.
Referring to
When the locking module 600 is located at the first movement through-hole end 502 in the state in which the hatch cover 100 is completely opened, the second locking-plate end member 222 may make contact with the locking module 600 to make it impossible for the rotation support 220 to move toward the locking module.
The lower base 500 may include the second locking-plate fixing member 530 protruding upward from the lateral area of the lower base 500. When the locking module 600 is located at the first movement through-hole end 502 in the state in which the hatch cover 100 is completely opened, the second locking-plate fixing member 530 may make contact with the locking plate member 220 to make it impossible for the rotation support 200 to move.
That is, when the locking module 600 is located at the first movement through-hole end 502 in the state in which the hatch cover 100 is completely opened, the movement of the rotation support 200 may be completely prevented by the locking module 600 and the second locking-plate fixing member 530 that make contact with the locking plate member 220.
When the hatch cover 100 is not allowed to move, the train hatch module 1 may fix the rotation support 200, which directly receives the driving force and supports the hatch cover 100, to prevent movement of each component. That is, the train hatch module 1 according to an embodiment may completely prevent the movement of the hatch cover 100 in a state in which the hatch cover 100 should not be operated, such as when the train is traveling or being repaired, thereby enabling safe travel or repair.
Referring to
The train hatch module 1 may further include the first protruding support 310 and the second protruding support 320.
The first protruding support 310 may be connected to the middle end of the rotation support 200. The first protruding support 310 may protrude from the middle end of the rotation support 200 in the lateral direction of the train and may support the hatch cover 100 while making contact with the inner surface of the hatch cover 100. The first protruding support 310 on the inner surface of the hatch cover 100 may extend from the middle end of the rotation support 200 to a lateral end area of the hatch cover 100 facing toward the side of the train along the inner surface of the hatch cover 100 and may have a shape curved depending on the curvature of the inner surface of the hatch cover 100.
The first protruding support 310 may support the hatch cover 100 while having a shape curved along the inner surface of the hatch cover 100. However, all sides of the first protruding support 310 do not have to be fixed to the hatch cover 100.
The second protruding support 320 may be connected to the middle end of the rotation support 200.
