Definitions

  • the present invention relates to a roof box for a public transport vehicle.
  • the present invention also relates to a vehicle equipped with such a box.
  • Roof boxes are used in many applications to protect equipment located on the roofs of vehicles such as buses, trains, or trams.
  • equipment protected include electrical control or transformation equipment designed to receive an electrical current supplied by a catenary from a pantograph, or fuel cell assemblies or thermal control devices such as air conditioners.
  • These chests generally include a box, delimiting a reception space, closed by a cover formed of sheets riveted to the box which serves as a support for each of the sheets.
  • This cover separates the interior of the chest from the exterior and thus plays a role in protecting the equipment contained in the chest.
  • the different sheets of the cover are generally sealed together.
  • the invention relates to a roof box according to claim 1.
  • the trunk lid according to the invention thus protects the sealant by preventing it from being directly exposed to rain, detergents when cleaning the trunk and/or solar radiation. The risks of deterioration of the sealant, and therefore of water infiltration inside the trunk, are therefore reduced.
  • the trunk has one or more of the characteristics of claims 2 to 8 taken in isolation or in all technically possible combinations.
  • the vehicle is according to claim 10.
  • FIG. 1 An example of a public transport vehicle 10 is shown in the Figure 1 .
  • the vehicle 10 is, for example, a train, a tram or even a bus. However, other types of vehicles 10 are also possible.
  • the vehicle 10 is, for example, an electric vehicle, that is to say a vehicle designed to be propelled by an electric motor 12.
  • an electric vehicle that is to say a vehicle designed to be propelled by an electric motor 12.
  • other propulsion modes are likely to be envisaged.
  • the vehicle 10 comprises a body 14, a pantograph 16, at least one electrical equipment 18 and a roof box 20 accommodating said equipment 18.
  • the vehicle 10 travels on a track, for example a railway track, by means of wheels 22.
  • the electric motor 12 is configured to drive the wheels 22 of the vehicle 10 when the motor 12 is supplied with an electric current.
  • the body 14 delimits at least one compartment 24 of the vehicle 10.
  • the body 14 is configured to separate each compartment 24 from the exterior of the vehicle 10.
  • the body 14 comprises, in particular, a roof 26 which delimits each compartment 24 in an elevation direction Z which is substantially vertical when the vehicle 10 is traveling on a horizontal track.
  • the compartment 24 is intended to receive passengers, goods and/or equipment of the vehicle 10.
  • the pantograph 16 is configured to come into contact with at least one catenary 28 when the vehicle 10 is in motion, and to receive a first electric current from the catenary(s) 28.
  • the pantograph 20 is further configured to transmit the first electric current to the equipment 18.
  • the equipment 18 is for example configured to convert the first current into a second current, and to transmit the second current to the electric motor 12.
  • FIG. 20 An example of a trunk 20 according to the invention is shown in more detail in the Figure 2 .
  • the trunk 20 is fixed to the roof 26, for example by screwing.
  • the trunk 20 extends in an elevation direction Z' substantially parallel to the elevation direction Z of the vehicle 10 when the trunk 20 is installed on the roof 26 of the vehicle 10.
  • the terms "upper”, “lower”, “towards up”, “down”, “above” and “below” will have as reference said elevation direction Z' of the trunk 20.
  • the trunk 20 comprises a box 30 and a cover 32 closing the box 30.
  • the box 30 and the cover 32 are configured to delimit an internal volume 34 of the trunk 30, and to separate said internal volume 34 from the exterior of the trunk 20.
  • the trunk 20 further comprises a mastic 36 disposed between the box 30 and the cover 32.
  • the trunk 20 further comprises a support 38 arranged between the roof 26 of the vehicle 10 and the body 30.
  • the support 38 thus has a lower face intended to be in contact with the vehicle 10, and an upper face, on which the body 30 rests.
  • the support 38 comprises for example a set of feet 39 on which the body 30 rests, each foot 39 being configured to be fixed to the roof 26, for example in a removable manner, and to then be integral with the body 30.
  • Each foot 39 is, for example, configured to be screwed to the roof 26.
  • the box 30 is configured to support the cover 32.
  • the box 30 is configured to maintain the cover 32 in a raised position relative to the body 14 of the vehicle 10 when the trunk 20 is mounted on the vehicle 10.

  • the intermediate wall(s) 44 divide(s) the internal volume 34 into at least two compartments. For example, each compartment is intended to receive a respective piece of equipment 18.
  • the box 30 includes a bottom wall 45 intended to support the equipment(s) 18 received in the trunk 20.
  • Each side wall 40, 41 rises from the bottom wall 45, according to its extension plane.
  • the structure of the body 30, in particular the number, shape and arrangement of the side walls 40, 41 and the intermediate wall(s) 44 is likely to vary.
  • the box 30 comprises four side walls 40, 41 whose respective extension planes extend substantially in the direction of extension Z' of the trunk 20.
  • each side and/or intermediate wall 40, 41, 44 has a polygonal contour.
  • each wall 40, 41, 44 is delimited in its respective extension plane by a closed polygonal contour.

  • the trunk 20 comprises a support 38
  • the bottom wall 45 is fixed to said support, for example by means of rivets.
  • At least one side wall 40, 41 extends on either side of the bottom wall 45, forming a so-called "water drop" profile.
  • said side wall 40, 41 bears on the edge of the bottom wall 45, a marginal portion of the side wall 40, 41 extending on the side of the external face of the bottom wall 45 in the elevation direction Z'.
  • said marginal portion goes below the external face of the bottom wall 45 in the elevation direction Z' over a height greater than 8 mm, for example between 8 mm and 10 mm, to constitute a water drop making it possible to vertically evacuate the residual water on the side walls 40, 41.
  • said side wall 40, 41 also preferably extends below the level of the upper face of the support 38 in the elevation direction Z'.
  • This overhang allows the water to run off along said side wall 40, 41 before falling towards the roof 26 and/or the ground, preventing the water from flowing along the base of the box 20, and in particular preventing water from stagnating at the level of the bottom wall 45 when the latter is present.

  • the cover 32 further comprises a peripheral skirt 56 located outside the body 30 and forming a rim of the cover 32.
  • the cover 32 has at least one opening 58 passing through the central part 54.
  • Each opening 58 allows access to the internal volume 34 of the trunk 20, and in particular to the equipment 18 located inside it, for example to carry out maintenance operations.
  • Each opening 58 also allows access to the internal volume 34 of the trunk 20 during the manufacture of the latter, for example to fix the cover 32 to the body 30 by welding, a weld bead 59 (visible on the Figure 3 ) then extending inside the trunk 20.
  • each opening 58 is at least partially closed by a panel (not shown).
  • the cover 32 is formed from a set of sheets 62.
  • Each sheet 62 has an internal face, forming a portion of the internal face 52A of the cover 32, and an external face, forming a portion of the external face 52B of the cover 32.

  • Such an angle ⁇ facilitates the application of the mastic 36 in the chute 70 and guarantees a good seal between the box 30 and the cover 32.
  • the mastic 36 bears on the internal face 52A of the peripheral skirt 56, preferably on the internal face 52A of the proximal and distal portions 66, 67 of the skirt 56, and on the external face 46B of the wall 40, 41 which faces said internal face 52A.
  • Sealant 36 is for example made of polymeric material, in particular polyurethane or silicone.
  • the peripheral skirt 56 the mastic 36 is not directly exposed to solar radiation, in particular to ultraviolet rays. This prevents degradation of the mechanical properties of the mastic 36 and increases its service life.
  • the manufacturing method comprises a step of providing the box 30, a step of providing the cover 32, a step of assembling the cover 32 on the box 30 and a step of applying the mastic 36 between the cover 32 and the box 30 to ensure the sealing of the trunk 20.
  • the side walls 40, 41 and, optionally, the intermediate wall(s) 44 and the bottom wall 45 are assembled together by welding or by riveting.
  • the sheets 62 are assembled together, preferably welded to each other, so as to form a set of single-piece sheets 62.
  • At least a portion of the sheets 62 has undergone a folding step so as to form the peripheral skirt 56 of the cover 32.
  • the cover 32 is placed on the box 30 so as to close said box 30.
  • the cover 32 then rests on the box 30, for example at the level of at least one side wall 40, 41 and/or an intermediate wall 44.
  • the cover 32 is then fixed to the body 30.
  • the cover 32 is for example welded onto the body 30 or is fixed onto the body 30 by means of rivets.
  • the presence of an opening 58 in the cover 32 allows an operator to have access to the interior volume 34 of the trunk 20 to carry out these fixings.
  • the cover 32 and the box 30 define between them a chute 70 as described previously.
  • the sealant 36 is applied, for example by means of a suitable gun, inside the chute 70.
  • the box 30 is then fixed to a support 38.
  • One or more electronic devices 18 are then arranged inside the trunk 20 and shutters are installed to close the openings 58.
  • the trunk 20 is then fixed, for example screwed, to the roof 26 of the vehicle 10.
  • the presence of the peripheral skirt 56 protects the sealant 36 from solar radiation, as well as from rain.
  • the sealant 36 is also protected at least in part from the detergents used when cleaning the vehicle 10. The sealant 36 thus retains its mechanical properties for longer, which prevents degradation or partial or total decohesion of the sealant 36.
  • the U-shaped or inverted V-shaped profile of the chute 70 promotes the flow of the liquid by gravity and prevents a rise by capillarity to the interior of the box 20, due to the length to be traveled in the chute 70.
  • the roof box 20 according to the invention thus presents a very limited risk of water infiltration, and thus has increased durability.
  • the peripheral skirt 56 does not extend over the entire circumference of the upper edge 49 of the body 30, but only over a portion of the circumference.
  • the peripheral skirt 56 comprises a plurality of skirt portions spaced apart from each other, the peripheral skirt 56 then being discontinuous.
  • each skirt portion extends opposite a respective side wall 40, 41.
  • peripheral skirt 56 is devoid of a proximal portion 66.
  • the junction 68 then directly connects the central part 54 of the cover 32 to the distal portion 67 of the skirt 56.
