Definitions
- TITLE AIR CONVEYING DEVICE WITH INCREASED GUIDING CAPACITY, AND ASSOCIATED BUMPER, FOR A LAND VEHICLE
- the invention relates to land vehicles, and more specifically to certain air conveying devices which are intended to equip land vehicles in areas liable to be struck by pedestrians.
- Certain land vehicles generally of the automobile type, comprise an area likely to be struck by a pedestrian and in which at least one piece of equipment is installed (sometimes itself consisting of equipment(s) and/or devices)).
- equipment can, for example, be a bumper (or shield), usually installed at the front, but can also be installed at the rear.
- a piece of equipment installed in the above-mentioned zone comprises other piece of equipment provided with holes (or passages) and above or below which is installed at least one air conveying device.
- conveying means allowing air to go from one place to another by being at least partially guided.
- a bumper can sometimes comprise an absorption device provided with holes (or passages) and intended to cushion the impact with a pedestrian, a first air conveying device installed above the absorption device and constituting a support reinforcement provided with at least one air inlet, and a second air conveying device installed below the absorption device and constituting a lower grid allowing the air inlet.
- Air passing through the support brace and lower grille is usually intended to supply other vehicle equipment, such as for example a radiator.
- part of the air which passes through the support reinforcement like part of the air which passes through the lower grille, enters some of the holes (or passages) of the absorption device, and therefore is not
- an air conveying device intended to equip a land vehicle in a first zone likely to be struck by a pedestrian and comprising a clean conveying part, on the one hand, to be installed above or below equipment provided with holes in the vehicle, and, on the other hand, to receive air and convey (or guide) this air towards a second zone situated downstream.
- This air conveying device is characterized in that its conveying part comprises a lower or upper part comprising at least one wall intended to be placed above or below the equipment by masking at least part of its holes to guide the air towards the second zone without it entering these masked holes and comprising at least one0 zone of weakening suitable for allowing its deformation when struck by a pedestrian.
- the air conveying device according to the invention may comprise other
- the (each) wall of the conveying part can comprise at least two masking sub-parts defined at different levels, participating in the masking, having a first thickness and joined together by a coupling sub-part having a second thickness strictly less than the first thickness in order to define a zone of weakening allowing, in the event of rupture, a translation of a masking sub-part relative to another masking sub-part;
- the (each) wall of the conveying part can comprise three masking sub-parts defined at three different levels and secured in pairs by two coupling sub-parts;
- the (each) wall of the conveying part can be an integral part of the conveying part.
- the invention also proposes a bumper intended to equip a front part of a land vehicle in a first zone likely to be struck by a pedestrian, and comprising equipment provided with holes.
- This bumper is characterized by the fact that it also includes at least one air conveying device installed above or below the equipment5 by concealing at least part of its holes.
- the bumper according to the invention may comprise other characteristics which may be taken separately or in combination, and in particular:
- its equipment may be a shock absorption device intended to be installed in a transverse direction of the vehicle; 0 - it can include an air conveying device installed above the equipment and constituting a support reinforcement; - it may include an air conveying device installed below the equipment and constituting a lower grid.
- the invention also proposes a land vehicle, optionally of the automotive type, and comprising a first zone likely to be struck by
- FIG.1 schematically illustrates, in a perspective view from the rear side, part of an exemplary embodiment of a bumper according to the invention5 comprising two exemplary embodiments of first and second air conveying devices according to the invention
- FIG.2 schematically illustrates, in a sectional view in a longitudinal and vertical plane, the bumper of [Fig.1],
- FIG.3 schematically illustrates, in a very slightly perspective view from the rear side, the first air conveying device of [Fig.1], and
- FIG.4 schematically illustrates, in a perspective view from the front side, the second air conveying device of [Fig.1],
- the object of the invention is in particular to propose an air conveying device DCm intended to equip a land vehicle or to form part of a bumper PC intended to equip a land vehicle in a first area likely to be struck by a pedestrian.
- each air conveying device DCm is intended to form part of a bumper PC, itself intended to equip a front part of a land vehicle.
- a device DCm air conveying according to the invention can be independent of a front bumper, when it is installed above or below equipment provided with holes, itself installed in a first zone of a land vehicle likely to be struck by a pedestrian.
- the land vehicle is of the automobile type.
- a car For example, a car.
- the invention is not limited to this type of land vehicle. It relates in fact to any land vehicle comprising at least a first zone likely to be struck by a pedestrian.
- the direction X is the longitudinal direction of the vehicle, which is parallel to the lateral sides comprising the side doors
- the direction Y is the transverse direction of the vehicle, which is perpendicular to the longitudinal direction X
- the direction Z is the vertical direction of the vehicle, which is perpendicular to the longitudinal5 X and transverse Y directions.
- a front bumper PC may comprise only one air conveying device DCm according to the invention, the latter (DCm) constituting for example a support reinforcement or a lower grille .
- an air conveying device DCm comprises at least one conveying part PG intended to equip a land vehicle in a first zone liable to be struck by a pedestrian and suitable for installation above or below EQ equipment provided with holes (or passages) TE and forming part of this land vehicle.
- the shape of the conveying part PG depends of the type of its DCm air conveying device.
- the shape of the support reinforcement DC1 (illustrated in Figures 1 and 3) differs significantly from the shape of the lower grid DC2 (illustrated in Figures 1 and 4).
- the support reinforcement DC1 includes at least one large air inlet EA (and here two)
- the lower DC2 grille includes a multiplicity of fins (or bars) spaced from each other defining air inlets between them.
- the equipment EQ is an absorption device intended to be installed transversely in the vehicle (that is to say in the transverse direction Y), and to dampen impact with a pedestrian during an impact.
- the conveying part PG is arranged in such a way as to receive air and to convey (or guide) this air received towards a second zone located downstream (relative to the direction of air circulation (here from the outside towards inside - the air5 entering through the front face FV of the bumper PC)
- this conveying part PG comprises a lower part PI (in the case of DC1) or an upper part PS (in the case of DC2) comprising at least one PM wall intended to be placed above or below the EQ equipment.
- PM wall is understood to mean a continuously solid element so as to define a surface on which the air can slide.
- wall PM comprises at least one zone of weakening ZA which is capable of allowing its deformation when it is struck by a pedestrian.
- PM wall is understood here to mean a continuously solid element so as to define a surface on which the air can slide.
- the masking of at least some of the holes TE prevents air from entering them and therefore makes it possible to increase the guiding capacity of the conveying part PG, which makes it possible to significantly increase the quantity of air which reaches the second zone, for example to supply a radiator of the land vehicle.
- the (each) zone of weakening ZA makes it possible to prevent its wall PM from constituting a hard point limiting the capacity damping of a pedestrian (HERE) of the PC bumper. Indeed, in the event of impact with a pedestrian, the (each) wall PM will deform and therefore participate in the damping of the pedestrian mainly provided by the absorption device EQ.
- the conveying part PG of the first air conveying device DC1 (here a support reinforcement) comprises a single wall PM, but it could comprise one several (at least two). It will also be noted that in the example illustrated without limitation in [Fig.4], the conveying part PG of the second air conveying device DC (here a lower grid) comprises two walls PM, but it could not contain only one or at least three.
- the wall PM can comprise at least two masking sub-parts SPMj defined at different levels and secured together by a coupling sub-part SPCk.
- Each masking sub-part SPMj participates in the masking of holes TE of the equipment EQ which are located below or above it, and has a first thickness.
- Each coupling sub-part SPCk has a second thickness which is strictly less than the first thickness in order to define a zone of weakening ZA which allows, when it breaks during a pedestrian impact, a translation of a sub-part of masking SPMj with respect to another sub-part of masking SPMj' (j' j).
- the first masking sub-part SPM1 is fixedly secured to its conveying part PG (in the lower part PI in the case of DC1 and in the upper part PS in the case of DC2), placed at a first level (vertical) and secured by a first coupling sub-part SPC1 to the second masking sub-part SPM20 which is placed at a second level (lower than the first level in the case of DC1 and higher than the first level in the case of DC2).
- the third masking sub-part SPM3 is placed at a third level (lower than the second level in the case of DC1 and higher than the second level in the case of DC2) and secured to the second masking sub-part SPM2 by a second coupling sub-part SPC2.
- the rupture of the first coupling sub-part SPC1 constituting a first weakening zone ZA allows the relative translation of the first masking sub-part SPM1 with respect to the second masking sub-part SPM2, and the breaking of the second coupling sub-part SPC2 constituting a second weakening zone ZA allows the relative translation of the second masking sub-part SPM2 (and therefore also of the first masking sub-part SPM1) by with respect to the third masking subpart SPM3.
- the (each) wall PM can form an integral part of the conveying part PG. This can in particular be done when the (each) conveying part is made by molding a plastic or synthetic material. But in a variant embodiment, the (each) wall PM could be a piece attached to its conveying piece PG, for example by gluing, welding, clipping or screwing.
