- TITLE LAND VEHICLE WITH FRONT COMPARTMENT SEALED BY A SEAL PRESSED ON A SUPPORTING SURFACE
- the present invention claims the priority of French application 2104055 filed on 04.19.2021, the content of which (text, drawings and claims) is incorporated herein by reference.
- the invention relates to land vehicles comprising a front compartment masked by a front bonnet, and more specifically the sealing in the upper front part of the front compartment of such vehicles. 5 State of the art
- Certain land vehicles often of the automobile type, comprise a front compartment which is concealed by a front cover.
- the latter is frequently associated with a seal making it possible to make the upper front part of the front compartment as airtight as possible in order to improve the aerodynamics of the vehicle and/or to prevent the entry of water and/or prevent the overpressure of air in the front compartment from exerting pressure on the bonnet (likely to induce vibrations).
- an upper bearing surface can be created on the assembled bumper (for example either on the skin of the bumper, or on a bumper reinforcement part), then secure this seal securely to this upper support surface which covers all the technical parts located in the upper front part of the vehicle, namely the bumper frame , the crosspiece, the right and left optical blocks (or projectors), and the fixings.
- the inner face of the front cover then exerts pressure on this seal when the latter is in the closed position.
- the aim of the invention is therefore in particular to improve the situation. 5
- a land vehicle comprising, on the one hand, a bumper frame comprising an upper edge terminated by two right and left ends to which are respectively secured lugs for fixing optical units each comprising an upper face, and, on the other hand, a front cover comprising an internal face covering in the closed position a front compartment by having a sub-part extending above the upper edge and upper faces.
- each fixing lug comprises a support wall extending the upper edge at the level of the corresponding end in the direction of the upper face of its optical unit
- each mounting lug can end just before the upper face of its optical unit so that they are separated by an opening promoting separation between this mounting lug and its optical unit in the event of an impact;
- the support wall of each fixing lug can extend to the upper face of its optical unit;
- each optical unit can be inclined relative to a horizontal plane of the vehicle by having an increasing level from its fixing lug.
- the support wall of each fixing lug can be inclined with respect to this horizontal plane at an increasing level from the corresponding end of the upper edge of the bumper reinforcement;
- each mounting bracket may comprise under its bearing wall at least one reinforcing rib extending to the corresponding end of the upper edge of the bumper reinforcement in order to prevent deformation of its bearing wall when the gasket is pressed against it;
- the seal can be fixedly attached to the upper edge, support walls and upper faces.
- the sub-part (of the inside face of the front bonnet) can rest continuously5 on the seal when the front bonnet is in the closed position;
- each of the upper edges, bearing walls and upper faces may comprise at least one hole to which is coupled a clip to which the seal is coupled;
- the seal can be fixedly secured to the sub-part of the inner face (of the front cover) which is part of a lining of the front cover, and can rest continuously against the upper edge, support walls and upper surfaces when the front cover is in the closed position;
- the liner may comprise holes to which clips are coupled to which the seal is coupled;
- FIG. 1 schematically illustrates, in a perspective view from the front side, a front left part of an example of a front compartment of a land vehicle according to the invention, with the seal installed,
- FIG. 2 schematically illustrates, in a front view of the front side, the left front part 5 of the land vehicle of Figure 1, before the installation of the seal,
- FIG. 3 schematically illustrates, in a sectional view in a vertical and longitudinal plane at the level of the support wall of the fixing lug of the left optical unit, the left front part of the land vehicle of FIG. 1, with the front bonnet in the closed position,
- FIG. 4 schematically illustrates, in a front view of the rear side, the fixing lug of the left optical unit of the land vehicle of FIG. 1
- FIG. 5 schematically illustrates, in a sectional view in a vertical and longitudinal plane at the level of the support wall of the mounting bracket of the left optical unit5, the bumper reinforcement of the land vehicle of FIG. 1 with the left headlight unit mounting bracket placed on the left end of its upper edge.
- the object of the invention is in particular to propose a land vehicle comprising a front bonnet CV masking in the closed position a front compartment CM whose upper front part is sealed and which is partly delimited by a bumper frame AP to which are attached optical units BO.
- the land vehicle is a motor vehicle, such as a car for example.
- the invention is not limited to this type of land vehicle. It relates in fact to any land vehicle comprising a front bonnet masking in the closed position a front compartment CM.
- the front compartment CM is an engine compartment accommodating at least part 0 of the powertrain (or GMP) of the land vehicle. But this is not mandatory. Indeed, the front compartment CM could be a storage space (or front trunk).
- front is defined in relation to the front end of the vehicle
- rear is defined in relation to the rear end of the vehicle (as opposed to the front end). Therefore, the front part (or face) of an element is oriented towards the front end of the vehicle, while the rear part (or face) of this element is oriented towards the rear end of the vehicle.
- the X direction is the longitudinal direction of the vehicle, which is parallel to the lateral sides comprising the side doors
- the Y direction is the transverse direction of the vehicle, which is perpendicular to the lateral sides and to the longitudinal direction X
- the Z direction is the vertical direction of the vehicle, which is perpendicular to the longitudinal X and transverse Y directions.
- This front compartment CM is intended to be masked by a front cover CV when the latter (CV) is in a closed (or folded down) position illustrated in FIG. 3. 0
- the front part of this front compartment CM is in particular delimited by a frame of bumpers AP and two optical units BO right and left (only the left being represented).
- each block optical BO is a projector (or headlight) providing at least one lighting function, such as for example a high beam function or a dipped beam function.
- the two right and left BO optical units are therefore installed respectively close to the right lateral (or longitudinal) sides
- the AP bumper frame is one of the elements of the vehicle's front bumper. It is fixedly attached to the structure of the vehicle. Although this does not appear in the figures, the front bumper also comprises a support fixedly secured to the bumper frame AP and to which the bumper skin is fixedly secured (part visible from the outside of the vehicle).
- this bumper reinforcement AP comprises an upper edge BS which is terminated by two right and left ends5 E (only the left is shown here) and to which are respectively secured fixing lugs PF right and left BO optical units (only the left is shown here).
- each fixing lug PF can be secured to the corresponding end E0 by screwing.
- it comprises a hole T1 intended to be crossed by a screw which is screwed into a threaded hole of the corresponding end E or into a nut placed behind another hole defined in the corresponding end E.
- Each optical unit BO comprises an upper face FS.
- each upper face FS is part of a housing BB of an optical unit BO, to which is fixedly attached a glass G through which photons come out which participate in each photometric function ensured by the latter (BO).
- the upper face FS could be part of the glass G.
- each fixing lug PF is part of the housing BB of the block optical BO. But in a variant embodiment, the fixing lug PF could be part of the crystal G.
- the front cowl CV comprises an internal face Fl which covers the front compartment CM in the closed position by having a sub-part SP which extends above the upper edge BS of the bumper reinforcement -shocks AP and upper faces FS of the optical blocks
- this internal face F1 can be part of a lining DC of the front cover CV.
- each fixing lug PF of an optical unit BO comprises a support wall PP which extends the upper edge BS of the bumper reinforcement AP at the level of the corresponding end E en0 towards the upper face FS of its optical block BO.
- the expression “which extends” here means which continues almost in continuity.
- the support wall PP is therefore oriented upwards (along Z).
- the vehicle also includes a seal JE which is responsible for sealing in an upper front part PS of the front compartment CM.
- this seal JE is fixedly fixed to the upper edge BS, bearing walls PP and upper faces FS, and consequently, the sub-part SP is continuously supported on the JE5 seal when the CV front cover is in the closed position, which presses the JE seal against the quasi-continuous bearing surface.
- the seal JE could be fixedly secured to the sub-part SP of the internal face Fl which extends above the upper edge BS of the bumper reinforcement AP and the upper faces FS of the optical blocks BO when the front cover CV is in the closed position. In this variant, it is therefore the seal JE which presses continuously against the upper edge BS, bearing walls PP and upper faces FS (and therefore against the quasi-continuous bearing surface) when the CV front cover is in the closed position.
- each fixing lug PF can end just before the upper face FS of its optical block BO so that they are separated by a 0 opening OF which favors the separation between this fixing lug PF and its optical unit BO in the event of an impact suffered.
- this opening OF local absence of material
- the bearing wall PP of each fixing lug PF could extend (without discontinuity) as far as the upper face FS of its optical unit BO.
- each optical unit BO can be inclined with respect to a horizontal plane XY of the vehicle by having an increasing level from its mounting bracket PF.
- the bearing wall PP of each fixing lug PF is inclined with respect to this horizontal plane XY having an increasing level from the corresponding end E of the upper edge BS.
- the inclination of the support wall PP is intended to pass from the level (along Z) of the upper edge BS (at the level of its end E) to the level (along Z) of the upper face FS (at the level of the interface with the fixing bracket PF). These inclinations are not necessarily linear (and therefore constant).
- each fixing lug PF may comprise under its support wall PP at least one reinforcing rib NR which extends to the corresponding end E of the upper edge BS, in order to to rely on it, as illustrated without limitation in Figures 4 and 5. This makes it possible, when the seal JE is pressed against the bearing wall PP, to prevent deformation of the latter (PP) (which could induce a local reduction in the quality of the seal).
- each fixing lug PF could comprise a single reinforcing rib NR or even more than two reinforcing ribs NR. 0 Note also, as illustrated without limitation in Figures 1, 2 and
- each of the latter (BS, PP and FS) can comprise at least one hole T2 to which is coupled a AF staple.
- the JE gasket is then coupled to each 5 AF clip.
- each support wall PP comprises only one hole T2
- the upper edge BS comprises at least three holes T2
- each upper face FS comprises at least two holes T2.
- this lining DC may comprise holes to which staples are coupled.
- the JE gasket is coupled to these DC liner clips.
- each end E may include an indexing pin PI erected5 in the vertical direction Z and intended to pass through a hole T3 defined in the fixing lug PF.
- This indexing pin PI facilitates the pre-positioning of the upper part of the optical unit BO on the corresponding end E before screwing it in via its hole T1. In addition, once tightened, it prevents rotation of the PF0 fixing lug concerned.
- each fixing lug PF which could comprise an indexing pin intended to pass through a hole defined in the corresponding end E.
