Description

{TRAIN HATCH MODULE WITH LOCKING DEVICE}

The present invention relates to a train hatch module capable of hiding or revealing a train coupler from the outside of the train.

High-speed trains are high-speed railway vehicles, and their front end is mostly shaped with aerodynamic considerations, such as a pointed shape, to reduce air resistance. This is because the air resistance of a high-speed train running at high speed increases in proportion to the square of the train's speed, and the impact due to the difference in air pressure increases when entering a tunnel.

Coupling is a component that connects trains on a railway, and is a component that is installed on all railway vehicles regardless of whether they are locomotives or passenger cars. The types of couplers for these trains include knuckle-type couplers, close-type couplers, and Schaffenberg-type couplers. Meanwhile, regardless of the type, not all of the aforementioned couplers have shapes that can minimize air resistance, so high-speed trains are equipped with hatches that can hide the couplers installed at the front.

The present invention provides a train hatch module that can be connected to a hatch body of a train while stably supporting a hatch cover that allows a connector to be exposed to the outside of the train only when connection with another train is required.

In addition, the present invention provides a train hatch module capable of stably preventing movement of a hatch cover when the hatch cover of a train's front end is completely opened or completely closed, thereby enabling safe operation or safe maintenance of a train.

In addition, the present invention provides a train hatch module in which a driving device that provides power to drive a hatch cover at the front of a train can be stably connected to a hatch body of a train, thereby preventing deterioration in the durability of each component of a train running at high speed.

The working principle and embodiments of the disclosed invention will be described with reference to the attached drawings below.

FIG. 1 is a drawing illustrating the exterior of a train hatch module according to one embodiment.

Referring to FIG. 1, the train hatch module (1) may include a hatch cover (100) and a hatch body (900).

The train hatch module (1) may be a device provided at the front of the lower part of the train and configured to expose the train's coupler to the outside or hide it inside.

The coupler of a train can be configured to connect two trains to each other. The couplers provided at the bottom of each of the two trains can be connected to each other to connect the two trains. However, the configuration of the coupler is mostly not aerodynamic, so if the coupler protrudes from the end of a train that is not connected, it can reduce the running performance of a high-speed train. Therefore, it is desirable that the coupler be hidden in the first and last cars of a high-speed train that runs at high speed and be exposed to the outside of the train only when it is necessary to connect with another train.

The hatch cover (100) is provided at the front of the lower part of the train and can be opened and closed by rotating sideways, and when opened, the train's connector can be exposed to the outside.

The hatch body (900) can be connected to the main body of the train so as to be positioned at the front of the train. The hatch body (900) can be provided with a configuration for supporting a hatch cover (100) and a configuration for driving a train hatch module (1).

Figure 2 is a drawing showing the interior of a train hatch module as viewed from the rear, and Figure 3 is a drawing showing the train hatch module with the hatch cover open as viewed from the front.

Referring to FIGS. 2 and 3, the train release module may include a rotation support (200), a first protruding support (310), a second protruding support (320), a lower rotation center member (510), a lower rotation shaft (511), an upper rotation center member (710), an upper rotation shaft (711), a horizontal actuator module (720), and a connecting rod (800).

The rotary support (200) may be configured to support the hatch cover (100) while coming into contact with the inner surface of the hatch cover (100). The rotary support (200) may be configured of a metal material as a frame that supports the hatch cover (100), but the rotary support (200) is not necessarily limited to being configured of metal.

The rotation support (200) can be configured to rotate around an upper rotation axis (711) connected to an upper end and a lower rotation axis (511) connected to a lower end. The rotation support (200) can be configured to be connected to an upper rotation center member (710) in such a way that the upper end is connected to the upper rotation axis (711), and to be connected to a lower rotation center member (510) in such a way that the lower end is connected to the lower rotation axis (511).

FIG. 4 is a drawing illustrating a lower base according to one embodiment.

Referring to FIG. 4, the train hatch module (1) may include a lower base (500). The lower base (500) may be connected to the hatch body (900) of the train and may be positioned lower than the connector. The lower base (500) may be formed of a plate and may be a member on which the components provided at the lower end of the train hatch module (1) among the components of the train hatch module (1) are provided.

The lower base (500) may include a lower rotation center member (510), a lower rotation center member (510), a first locking plate fixing member (520), and a second locking plate fixing member (530).

A lower rotation center member (510) may be provided at the top of the lower base (500) and a lower rotation axis (511) may be provided as the center around which the rotation support member (200) rotates.

The lower rotation axis (511) may be a central axis around which the rotation support (200) rotates, while being located at the top of the lower base (500). The lower rotation axis (511) may be a central axis facing the upper and lower directions of the train. In other words, when the rotation support (200) rotates around the lower rotation axis (511), it may rotate around the lower central axis when viewed from the upper or lower direction of the train, while simultaneously moving in the lateral direction of the train.

FIG. 5 is a drawing illustrating an upper base according to one embodiment.

The train hatch module (1) may include an upper base (700). The upper base (700) may be connected to the hatch body (900) of the train and may be positioned above the connector. The upper base (700) may be formed of a plate and may be a member on which the components provided on the upper side of the train hatch module (1) among the components of the train hatch module (1) are provided.

The upper base (700) may include an upper rotation center member (710), a horizontal actuator module (720), and a slide drive member (730).

The horizontal actuator module (720) may be provided at the bottom of the upper base (700) and configured to face the forward and rearward direction of the train.

The upper rotation center member (710) may be positioned at the bottom of the upper base (700) and an upper rotation axis (711) may be provided.

The upper rotation axis (711) may be a central axis that is located at the bottom of the upper base (700) and serves as a center around which the rotation support (200) rotates. The upper rotation axis (711) may be a central axis that faces the upper and lower directions of the train. In other words, when the rotation support (200) rotates around the upper rotation axis (711), it may rotate around the upper central axis when viewed from the upper or lower direction of the train, and at the same time move in the lateral direction of the train.

FIG. 6 is a drawing illustrating a process of opening a hatch cover according to one embodiment.

Referring to FIG. 6, it can be confirmed that force is transmitted to the connecting rod (800) according to the driving of the slide driving unit (730), causing the connecting rod (800) to move, and that the rotating support (200) moves as the connecting rod (800) moves.

The slide drive unit (730) may be provided at the bottom of the upper base (700) and configured to move forward or backward of the train along the horizontal actuator module (720).

The slide driving unit (730) may be configured to provide a driving force required for opening and closing the hatch cover (100) while moving along the horizontal actuator module (720). Specifically, the slide driving unit (730) may be provided at the lower end of the upper base (700) and may provide a driving force that allows the rotary support (200) to rotate while moving along the horizontal actuator module (720) toward the front of the train or the rear of the train. The driving force of the slide driving unit (730) may be a force generated by the slide driving unit (730) itself, or a force transmitted to the slide driving unit (730) by the horizontal actuator module (720).

The train hatch module (1) may further include a connecting rod (800). The connecting rod (800) may have one end connected to the slide driving unit (730) and the other end connected to the top of the rotating support (200), thereby connecting the slide driving unit (730) and the rotating support (200). The connecting rod (800) may be a rod made of metal, but the material of the connecting rod (800) is not limited thereto.

The connecting rod (800) can directly transmit the power received from the slide driving unit (730) to the rotating support (200). The connecting rod (800) can transmit the power received from the slide driving unit (730) to the rotating support (200) while the slide driving unit (730) moves toward the rear of the train. The rotating support (200) can rotate around the upper rotation axis (711) and the lower rotation axis (511) by the power received from the connecting rod (800).

However, the connecting rod (800) is not necessarily limited to transmitting the force to the rotary support (200). For example, the connecting rod (800) may have one end connected to the slide driving unit (730) and the other end directly connected to the hatch cover (100), so that the force received from the slide driving unit (730) may be directly transmitted to the hatch cover (100).

The hatch cover (100) can rotate around the upper rotation axis (711) and the lower rotation axis (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) transmits the force received from the slide driving unit (730) to the rotation support (200) while the slide driving unit (730) moves toward the rear of the train, thereby allowing the hatch cover (100) connected to the rotation support (200) to open while rotating.

FIG. 7 is a drawing showing the train hatch module with the hatch cover closed as seen from above, FIG. 8 is a drawing showing the train hatch module in operation as seen from above, and FIG. 9 is a drawing showing the train hatch module with the hatch cover open as seen from above.

The slide drive unit (730) of the horizontal actuator module (720) moves along the front or rear of the horizontal actuator module (720), and the connecting rod (800) is completely fixed to the slide drive unit (730) and can move in the same direction as the slide drive unit (730). At this time, since the connecting rod (800) is connected to a rotary support (200) that performs a rotary movement, if the horizontal actuator module (720) is fixed without moving on the upper base (700), the driving of the slide drive unit (730), the movement of the connecting rod (800), and the rotation of the rotary support (200) may be impossible.

Referring to FIGS. 7, 8, and 9, the upper base (700) may be provided with a horizontal actuator rotation axis (701) that serves as a center for the rotation of the horizontal actuator module (720). At this time, it can be confirmed that the horizontal actuator module (720) moves toward the side of the train as the hatch cover (100) rotates and then moves toward the center of the train again.

The horizontal actuator module (720) can rotate about the horizontal actuator rotation axis (701). Specifically, the horizontal actuator module (720) can rotate about the horizontal actuator rotation axis (701) so that the connecting rod (800) faces the same direction as the direction in which the connecting rod (800) extends when the direction in which the connecting rod (800) extends changes as the rotating support (200) rotates.

The horizontal actuator rotation shaft (701) may be provided between the horizontal actuator module (720) and the upper base (700) so that the horizontal actuator module (720) may be configured to be connected to the upper base (700). That is, the horizontal actuator module (720) may be connected to the upper base (700) in a manner that it is suspended from the upper base (700) by the horizontal actuator rotation shaft (701).

However, since the horizontal actuator module (720) is connected to the upper base (700) only by the horizontal actuator rotation shaft (701), the load of the horizontal actuator module (720) is excessively concentrated in a certain area because it is suspended from the upper base (700) only by one configuration, and this may lead to a decrease in the durability of each component, and thus may not be desirable as a configuration of a high-speed train.

The upper base (700) may be configured to form an upper moving aperture (702). The upper moving aperture (702) may be a aperture penetrating from the upper to the lower portion of the upper base (700). The upper moving aperture (702) may be configured to move laterally in the direction in which an axis having a circular cross-section is extended. That is, the upper moving aperture (702) may have a width equal to the width of the axis passing through the upper moving aperture (702), and a length greater than the width of the axis passing through the upper moving aperture (702).

The horizontal actuator module (720) may include a horizontal actuator travel shaft (721) configured to penetrate the upper travel aperture (702) at the top. The horizontal actuator travel shaft (721) may be movable laterally along the upper travel aperture (702) of the train.

Since the horizontal actuator module (720) is connected to the upper base (700) by the horizontal actuator rotation axis (701) and the horizontal actuator movement axis (721), the load of the horizontal actuator module (720) can be distributed compared to when it is hung on the upper base (700) by only one configuration, and the deterioration of the durability of each component can be prevented.

Figure 10 is a drawing showing the lock plate member and the lock module when the hatch cover is closed as viewed from the inside, and Figure 11 is a drawing showing the lock plate member and the lock module when the hatch cover is open as viewed from the front.

Referring to FIGS. 10 and 11, the rotation support (200) may include a locking plate member (220) provided at the bottom of the rotation support (200). The locking plate member (220) may be a rectangular parallelepiped housing with one side open as illustrated, but the shape of the locking plate member (220) is not limited thereto.

The lower base (500) may be configured to form a lower movement aperture (501). The lower movement aperture (501) may be a aperture penetrating from the upper part to the lower part of the lower base (500). The lower movement aperture (501) may be configured to move laterally in the direction in which an axis having a circular cross-section is extended. That is, the lower movement aperture (501) may have a width equal to the width of the axis passing through the lower movement aperture (501), and a length greater than the width of the axis passing through the lower movement aperture (501).

The train hatch module (1) may further include a locking module (600). The locking module (600) may be a member capable of preventing movement of the rotation support (200) so that the hatch cover (100) can be maintained in a fully open state or a fully closed state.

The locking module (600) may have an axis shape, but the shape of the locking module (600) is not limited thereto. The locking module (600) may be configured to protrude from the upper portion of the lower base (500) by penetrating the lower moving hole (501).

The locking module (600) may be movable toward the side of the train along the lower moving aperture (501). The locking mode may be a state of the train hatch module (1) not moving, such as when the hatch cover (100) is fully opened or fully closed. The driving mode may be a state of the train hatch module (1) in which the slide driving unit (730) is being driven and the rotary support (200) and the hatch cover (100) are moving.

The locking module (600) may be configured to be positioned at the first moving aperture end (502) of the lower moving aperture (501) when the train hatch module (1) is in the locking mode. The first moving aperture end (502) may be the end of the lower moving aperture (501) toward the train side. The locking module (600), when positioned at the first moving aperture end (502), may be configured to contact the locking plate member (220) to prevent rotation of the rotation support (200).

The locking module (600) may be configured to be positioned at the second moving aperture end (503) of the lower moving aperture (501) when the train hatch module (1) is in drive mode. The second moving aperture end (503) may be the end of the lower moving aperture (501) toward the center of the train.

Referring to FIG. 10, the locking plate member (220) may include a first locking plate end member (221) provided at one end of the lower side.

The first locking plate end member (221) can contact the locking module (600) so that movement of the rotating support (200) in the direction of the locking module is impossible when the locking module (600) is positioned at the first moving aperture end (502) while the hatch cover (100) is completely closed.

The lower base (500) may include a first locking plate fixing member (520) protruding upward from a front area of the lower base (500). The first locking plate fixing member (520) may be configured to contact the locking plate member (220) to prevent movement of the rotation support (200) when the locking module (600) is positioned at the first movable aperture end (502) in a state where the hatch cover (100) is completely closed.

That is, when the hatch cover (100) is completely closed and the locking module (600) is positioned at the first moving hole end (502), the rotation support (200) can be completely prevented from moving by the locking module (600) and the first locking plate fixing member (520) that contact the locking plate member (220).
