Description

rail vehicle

The present invention relates to a railway vehicle.

Many railway vehicles include control desks, generally comprising control devices provided to allow a driver of the vehicle to control movement of the vehicle and to modify the speed of the vehicle.

Such pilot consoles are generally placed at the ends of the vehicle in order to allow the pilot to observe the zone in which the vehicle is moving and in particular to detect any obstacles without the aid of additional sensors. These consoles are generally two in number, one at each end of the vehicle, in order to allow the vehicle to move either in one direction or in the other. Consequently, when the vehicle is in operation, at most only one of the two desks is used at any time. In other cases, the vehicle is designed to be controlled remotely or even to move autonomously without the intervention of a driver, in which case the control desks are only used in exceptional circumstances, for example in the event of failure of the remote control system, or to move the vehicle, in the absence of passengers, in vehicle storage areas.

Consequently, it is known, in order to increase the available space and therefore the reception capacity of the vehicle, to allow passengers to access the area in which the cockpit is accommodated when this console is not used. For example, it is planned to place an additional cover on the consoles making it possible to make the piloting console inaccessible to the passengers. In other cases, the desk is retractable by translation in side supports placed on either side of the front window of the vehicle.

However, these solutions are not optimized. In particular, the removable covers are complex to put in place and their presence, in addition to the desk itself, limits the field of vision of the passengers through the front window of the vehicle. Consoles that can be retracted by translation in side supports necessarily have a large clearance, which poses the risk that the cables connecting the console to the other equipment of the vehicle are damaged during movement of the console and which therefore limits the reliability of the vehicle.

There is therefore a need for a vehicle comprising a cockpit, which is compatible with the presence of passengers in the area surrounding the console, which allows a large field of vision for the passengers, while having better reliability than the vehicles of the state of the art.

To this end, it is proposed a railway vehicle comprising a railway vehicle control desk and a support, the support being configured to support the control desk, the support comprising a first upper face delimiting the support in a direction of elevation of the railway vehicle, the desk comprising steering means of the railway vehicle, the console being rotatable relative to the support between at least one deployed position in which the steering means are accessible for an operator and a retracted position in which the steering means are inaccessible for the operator , the desk being accommodated in a cavity of the support when the desk is in the retracted position, the desk extending out of the support from the first upper face when the desk is in the deployed position.

According to advantageous but not mandatory aspects, the vehicle includes one or more of the following characteristics taken individually or in all technically possible combinations:

- the cavity opens onto the first upper face, the console comprising a console carrying the piloting means and a cover delimiting the console in the direction of elevation, the cover closing off the cavity when the console is in the retracted position, the console being inserted between the cover and the support when the desk is in the deployed position.

- the console has at least one active face carrying the control means, the cover comprising a portion projecting with respect to the active face in a direction substantially perpendicular to the active face, the projecting portion having in particular a length of between 10 centimeters and 20 centimeters.

- the cover is movable relative to the active face between a first position and a second position, the length of the portion projecting in the first position being strictly greater than the length of the portion projecting in the second position.

- the cover is configured to move from the first position to the second position when the console moves from the retracted position to the extended position.

- the support comprises at least one support face, the cover coming to bear against the support face when the desk is in the retracted position, the cover being remote from the support face when the desk is in the deployed position , the bearing face being in particular a face of a shoulder projecting inside the cavity.

- the railway vehicle comprises a seal interposed between the cover and the support face when the console is in the retracted position, the seal being configured to prevent a liquid from entering the cavity from the first upper face when the desk is in the retracted position.

- the desk has a second upper face delimiting the desk in the elevation direction, the second upper face being level with the first upper face when the desk is in the retracted position.

- an angular difference between the deployed position and the retracted position is between 30 degrees and 40 degrees.

- the desk is rotatable relative to the support along a substantially horizontal axis, the axis being, in particular, perpendicular to a longitudinal direction of the rail vehicle, the vehicle being configured to move along the longitudinal direction.

Characteristics and advantages of the invention will appear on reading the following description, given solely by way of non-limiting example, and made with reference to the appended drawings, in which:

FIG. 1 is a perspective view of an example of a cockpit of a railway vehicle according to the invention, comprising a cockpit, and

Figure 2 is a schematic sectional representation of the control panel of Figure 1.

An example of a cockpit 10 of a rail vehicle is shown in Figure 1.

The railway vehicle is, for example, a metro, a tram, or even a train.

The cockpit 10 is arranged at one end of the railway vehicle. In particular, the rail vehicle 10 is able to move in a longitudinal direction DL, the longitudinal direction DL being in particular a direction in which the rail vehicle has its largest dimension, the rail vehicle 10 being delimited in the longitudinal direction DL by the cockpit 10.

The cockpit 10 is, in particular, interposed along the longitudinal direction DL between a passenger compartment of the rail vehicle and the outside of the rail vehicle.

According to the example shown in Figure 1, the cockpit 10 includes a windshield 15, a support 20, a cockpit 25 and, optionally, a seat 30 for the pilot.

The windshield 15 is provided to allow a person present in the cockpit 10 to observe the exterior of the railway vehicle in the longitudinal direction DL. According to the embodiment shown in Figures 1 and 2, the windshield 15 is inclined towards the interior of the vehicle, that is to say that an upper end of the windshield 15 is interposed, in the longitudinal direction DL, between a lower end of the windshield 15 and the opposite end of the rail vehicle.

The support 20 is also called “trim”, in particular “front trim” or “rear trim”.

Support 20 is configured to support console 25.

The support 20 is interposed, along the longitudinal direction DL, between the windshield 15 and the seat 30.

The support 20 is, in particular, accommodated in a delimited space, according to a direction of elevation Z of the vehicle, by a floor of the cockpit 10 and by the windshield 15. The direction of elevation Z is a direction provided for be a vertical direction when the vehicle is in operation, in particular when the vehicle is moving on a horizontal portion of railway track.

The support 20 extends transversely to the vehicle 10. In particular, the support 20 extends in a transverse direction DT perpendicular to the longitudinal direction DL and to the elevation direction Z. According to one embodiment, the support 20 s extends transversely from one side wall to another of the cockpit 10.

The support 20 has a first upper face 35, a first support face 37 and a longitudinal face 40. The support 20 also defines a cavity 42.

The upper face 35 delimits the support 20 in the elevation direction Z. In particular, the support 20 is delimited, in the elevation direction Z, by the ground and by the first upper face 35.

The first upper face 35 is oriented away from the ground in the elevation direction Z.

The first upper face 35 is, for example, curved. In particular, the first upper face 35 has a convex profile in a plane perpendicular to the transverse direction DT.

A distance between the first upper face 35 and the ground is, for example, between 95 centimeters (cm) and 115 cm, in particular between 100 cm and 110 cm. However, this distance may vary.

The longitudinal face 40 delimits the support 20 along the longitudinal direction DL. In particular, the longitudinal face 40 is oriented along the longitudinal direction DL towards the interior of the vehicle 10, in particular towards the seat 30 and/or the passenger compartment.

The cavity 42 opens onto the first upper face 35.

The cavity 42 extends, for example, substantially along the elevation direction Z.

The console 25 comprises means 45 for piloting the vehicle 10. In particular, the console 25 comprises a console 50 for piloting the vehicle and a cover 55. The console 25 also has a second upper face 60.

The console 25 is movable relative to the support 20 between a retracted position and an extended position. In particular, the console 25 is rotatable between the retracted position and the deployed position around an axis of rotation A.

The axis of rotation A is, for example, substantially perpendicular to the longitudinal direction DL and to the elevation direction Z. In particular, the axis of rotation A is parallel to the transverse direction DT.

The term "substantially" is understood for a direction, in particular, as indicating an orientation within 15 degrees (°). Thus, a direction "substantially perpendicular" to another forms with it an angle between 75° and 105°.

The axis of rotation A is, in particular, inserted in the longitudinal direction DL between the console 25 and the end of the vehicle. The axis of rotation A is, moreover, interposed between the first upper face 35 and the ground.

When the console 25 is in the deployed position, the control means 45 are accessible to an operator. For example, when the console 25 is in the deployed position, the console 25 extends out of the support from the first upper face 35. In other words, in the deployed position, the console 25 protrudes from the first upper face 35. In this position, the first upper face 35 is interposed, in the elevation direction Z, between at least a part of the desk 25 and the ground.

When the console 25 is in the retracted position, the control means 45 are inaccessible to the operator. In particular, when the console 25 is in the retracted position, the console 25 is received in the cavity 42, in particular completely received in the cavity 42.

An angular difference α between the extended position and the retracted position is, for example, between 30° and 40°. The angular difference α is measured in a vertical plane between a straight line crossing a point of the desk 25 and the axis of rotation A when the desk 25 is in the deployed position and a straight line crossing the same point of the desk 25 and the axis of rotation A when the console 25 is in the retracted position.

In Figure 1, the console 25 is shown in the deployed position. The console 25 is shown in Figure 2 in solid lines in the deployed position, and in the retracted position in broken lines.

The console 25 is configured to cooperate with the support 20 to maintain the console 25 in its retracted position and/or in its deployed position in the absence of action by an operator. For example, the desk 25 and/or the support 20 comprise means for locking the desk 25 in the deployed position and/or in the retracted position. These locking means comprise for example electromechanical means for moving a locking pin carried by the support 20 towards a corresponding cavity of the console 25.

The locking means are, in particular, provided to allow the console 25 to support a load greater than or equal to 60 kilograms, for example greater than or equal to 80 kilograms, when the console 25 is in the deployed position.

The desk 25 comprises, in certain embodiments, moving means capable of moving the desk from the retracted position to the deployed position or vice versa. These moving means comprise, for example, one or more gas cylinder(s), one or more springs, or other types of moving means or actuators.

The second upper face 60 delimits the console 25 in the elevation direction Z. The second upper face 60 is, in particular, oriented away from the ground.

In particular, the second upper face 60 is, among the faces of the desk 25 delimiting the desk 25 in the elevation direction Z, the face furthest from the ground.

The second upper face 60 is, for example, level with the first upper face when the desk 25 is in the retracted position.

The piloting means 45 are configured to allow a pilot of the vehicle to command a movement of the vehicle in at least the longitudinal direction DL. The piloting means 45 comprise, for example, a member operable by the pilot to control a movement of the vehicle, a member operable by the pilot to modify a speed and/or an acceleration of the vehicle, and/or display means on the less than one vehicle speed. It should be noted that many other organs operable by the pilot and/or means of communicating information to the pilot are likely to be included in the piloting means 45.

The console 50 carries the control means 45. For example, the console 50 comprises a box 65 and one or more control modules.

The box 65 has at least one control face carrying the control means 45. In the example shown in FIGS. 1 and 2, the box 65 has two active faces, one being substantially vertical when the console 25 is in the deployed position, the other active face being substantially horizontal when the desk 25 is in the deployed position.

The substantially horizontal active face is, for example, arranged at a height, measured from the ground in the elevation direction Z, of between 95 cm and 115 cm, in particular between 100 cm and 110 cm. However, this height may vary.

Each active face is accessible to the pilot when the console 25 is in the deployed position.

The housing 65 is, for example, made of a plastic material.

Each control module is configured to convert information transmitted by the control means 45 into understandable commands for the active components of the vehicle, and vice versa. The active members include, for example, at least one motor, brakes, or even lighting of the vehicle.

Each control module is accommodated in a chamber delimited by the box 65.

Each control module and/or the corresponding control means or means are connected to the corresponding active components via electrical connectors and/or pneumatic or hydraulic conduits. These connectors and/or these ducts pass through, for example, the casing 65 at the level of a rear face of the casing 65, that is to say a face directed in the longitudinal direction DL towards the windshield 15. As a variant, these connectors and/or these conduits pass through the housing 65 at the level of an underside of the housing 65.

A distance between the axis of rotation A and an outlet orifice of at least one connector and/or of at least one conduit outside the box 65 is, for example, between 80 millimeters (mm) and 200 mm.

The cover 55 delimits the console in the elevation direction Z. In particular, the second upper face 60 is a face of the cover 55.

The cover 55 is configured to close the cavity 42 when the console 25 is in the retracted position. For example, the cover 55 is complementary to the opening formed by the cavity 42 on the first upper face 35.

The cover 55 delimits the bracket 50 in the elevation direction Z, the bracket 50 being in particular interposed in the elevation direction Z between the support 20 and the cover 55 when the desk 25 is in the deployed position.

The cover 55 is configured to bear against the support face 37 when the desk 25 is in the retracted position. When the console 25 is in the deployed position, the cover 55 is remote from the support face 37.

The bearing face 37 is, for example, an upper face of a crown extending radially inwards in the cavity 42, in particular a face delimiting the crown in the elevation direction Z. The crown is, for example, formed by a shoulder formed in the faces of the support 20 which delimit the cavity 42. The shoulder then protrudes into the cavity 42. The crown or the shoulder surrounds, for example, the cavity 42 in a plane perpendicular to the elevation direction Z.

Alternatively, the support face 37 is a portion of the first upper face 35.

A seal is, in particular, inserted between the bearing face 37 and the cover 55 when the cover 55 is in the retracted position. This seal is configured to prevent liquid from entering the cavity 42 from the first upper face 35 when the console 25 is in the retracted position. The joint is, for example, a peripheral joint surrounding the bracket 55 in a plane perpendicular to the direction of elevation Z.

The cover 55 is configured to support a load greater than or equal to 100 kilograms (kg), in particular greater than or equal to 200 kg, when the cover 55 bears against the support face 37. In particular, the cover 55 is configured to support a load greater than or equal to 240 kg when the cover 55 bears against the bearing surface 37.

The cover 55 is, for example, made in the form of a sheet or plate of a plastic or metallic material, for example a polyester sheet. According to one embodiment, the polyester sheet further comprises glass or carbon fibers.

The cover 55 is, for example, made of an opaque material.

The cover 55 has a thickness of between 4 mm and 7 mm.

Cover 55 includes at least one portion 70 projecting from one of the active faces, in particular from a substantially vertical active face when console 25 is in the deployed position. In the deployed position, the cowl 55 protrudes with respect to the corresponding active face in the longitudinal direction DL, in particular in a direction opposite to the windshield 15. In the deployed position, the cowl 55 protrudes over a length in particular comprised between 10 centimeters (cm) and 20 cm.

Cover 55 is movable relative to bracket 50 between a first position and a second position.

The cover 55 is, in particular, configured to move between the first position and the second position when the desk 25 is moved between the retracted position and the deployed position.

When the console 25 is in the retracted position, the cover 55 is in the first position. When the console 25 is in the deployed position, the cover 55 is in the second position.

When the cover 55 is in the first position, the length of the protruding portion 70 is strictly greater than the length of this same portion in the second position. For example, when the cowl 55 moves from the first to the second position, the cowl 55 moves along the longitudinal direction DL towards the windshield 15. A difference between the length of the portion 70 in the first position and the length of the portion 70 in the second position is between 130 mm and 150 mm.

The console 25 mobile in rotation allows the control means 45 to be inaccessible to the passengers when the console 25 is in the retracted position, while limiting the stresses exerted on the cables connecting the console 25 to the rest of the vehicle since the amplitude of the movement of the console 25 at the rear part of the console 25 is low. The railway vehicle is therefore more reliable.

In addition, the desk 25, in the retracted position, does not obstruct the vision of the passengers, whose travel comfort is therefore improved.

The sealing of the cavity 42 by the cover 55 in the retracted position prevents objects from being introduced by the passengers into the cavity and interfering with the operation of the console 25. The seal makes it possible in particular to protect the piloting means 45 and associated electronics against liquids spilled by passengers.

The protruding portion 70 acts as a visor and allows a good view of the piloting means 45 by the pilot even in the event of direct sunlight. A length of 10 to 20 cm is particularly suitable for this.

When the cover 55 bears against the support 20, in particular against the bearing face 37, the console 25 is made more resistant to loads in its retracted position.

An angular difference of 30 to 40° between the deployed and retracted positions allows in particular that the desk 25, and in particular the active faces, are oriented in the retracted position so that a liquid which would be introduced into the cavity 42 does not stagnate not on the active faces but flows along them. The risk of subsequent damage to the desk 25 is therefore reduced.

A horizontal axis of rotation A allows a console 25 of simple shape to be easily integrated into most supports 20 having the usual shapes, with a simple rotation mechanism.

A variation of the example vehicle shown in Figure 1 is now described. The elements identical to the example of figure 1 are not described again. Only the differences are highlighted.

Two or more separate deployed positions are defined for desk 25.

For example, in a first deployed position, the substantially horizontal active face is arranged at a height comprised between 80 cm and 90 cm, while in a second deployed position this height is comprised between 100 cm and 110 cm.

In particular, when the console 25 is in the first deployed position, the cover 55 is in its first position, but the cover 55 is in its second position when the console 25 is in the second deployed position.

Thus, the console 25 in the second deployed position is suitable for driving by a standing pilot, the portion 70 not forming an obstacle to the vision by the pilot of the active faces even if the pilot is tall.

The locking means are suitable for locking the console 25 indifferently in each of its deployed positions.

This variant allows the console 25 to be easily adapted to different pilot positions, in particular positions in which the pilot is seated or standing, and to different pilot sizes. Indeed, it suffices to choose a deployed position adapted to the morphology or to the position of the pilot, without the console 25 or the support 20 having to be modified.
