Description

SECURELY GLUE TRUNK FLAP, FOR ONE VEHICLE Technical field of the invention

The invention relates to vehicles comprising a structure defining a trunk, and more specifically trunk flaps which are intended to control access to such a trunk.

State of the art

Certain vehicles (generally of the automobile type) include a structure defining in one part (generally the rear) a trunk, access to which is controlled by a trunk flap mounted to rotate.

Some trunk lids include a molded part, often called a "flap liner," to which a top panel is glued to an upper portion and a lower panel to a lower portion.

For this purpose, the lower and upper parts comprise first bonding zones which receive glue for bonding corresponding second bonding zones of the lower and upper panels.

When an upper or lower panel is pressed against the shutter lining which has just received the glue in its first bonding zones, this glue is crushed and therefore spreads. It can then happen that glue escapes from a first bonding zone and/or a second bonding zone and reaches a neighboring zone which should not contain glue. This may in particular be the case when a bonding zone is located next to a coupling zone in which equipment must be attached and coupled. For example, a coupling zone may include a through hole capable of being crossed by a screw capable of ensuring the coupling of an optical unit on the shutter lining and/or a lower or upper panel. It will be understood that the presence of glue in such a through hole can prevent the screw from passing through and therefore the optical unit from coupling to the shutter lining and/or to the lower or upper panel.

It often proves difficult, if not impossible, to remove the glue from the coupling area without damaging the latter, and therefore in this situation we are generally forced to scrap the trunk lid, which induces significant additional cost and produces waste which must then be treated, which induces another additional cost and pollution and/or discharges which are possibly harmful to the environment.

The invention therefore aims in particular to improve the situation.

Presentation of the invention

It proposes in particular for this purpose a trunk flap, intended to equip a structure of a vehicle, and comprising a flap lining comprising lower and upper parts comprising first bonding zones to receive glue for bonding of second zones corresponding gluing of lower and upper panels.

This trunk flap is characterized in that at least one of the first and second bonding zones comprises at least one protective rib defined at the periphery of at least part of a predefined zone and capable of preventing the entry of the glue into the latter during gluing.

Thanks to the invention, there is no longer any risk of having to remove glue in a coupling zone, or even of being forced to scrap the trunk lid, which is advantageous economically and in terms of pollution and discharges.

The trunk flap according to the invention may include other characteristics which can be taken separately or in combination, and in particular:

- at least two first bonding zones and/or two second bonding zones may respectively comprise two protective ribs which are defined respectively at the periphery of parts of at least two predefined distant zones;

- the first and second bonding zones may respectively comprise first and second protective ribs, defined at the periphery of first and second predefined zones which must be placed facing each other, and capable of being pressed against each other against the other;

- at least one predefined zone may include a through hole capable of being crossed by a coupling element capable of ensuring coupling of equipment to the shutter lining;

- at least one protective rib may have a semi-circular shape;

- its shutter lining can be made with each protective rib by molding a plastic material.

The invention also proposes a vehicle, possibly of the automobile type, and comprising, on the one hand, a structure defining a trunk, and, on the other hand, a trunk flap of the type of that presented above and mounted to rotate on the structure so as to control access to this safe.

For example, this vehicle can also include two optical units fixedly secured to the flap lining and to the lower panel at respectively two predefined zones.

Detailed description of the invention

The invention aims in particular to propose a VC trunk flap with secure gluing, and intended to equip part of a structure of a vehicle to control access to a trunk.

In what follows, we consider, by way of non-limiting example, that the vehicle is of the automobile type. This is for example a car. But the invention is not limited to this type of vehicle. It concerns any vehicle comprising a structure defining in part a trunk, access to which must be controlled by a trunk flap mounted to rotate.

Furthermore, we consider in what follows, by way of non-limiting example, that the trunk is defined in the rear part of the structure of the vehicle. But the trunk could be defined in the front part of the vehicle structure.

In Figures 1 to 5, the direction longitudinal X, and the Z direction is the vertical direction of the vehicle, which is perpendicular to the longitudinal X and transverse Y directions.

We have schematically illustrated in Figures 1 to 3 an exemplary embodiment of a trunk flap VC according to the invention, intended to equip a part (here rear) of a structure of a vehicle (here automobile) to control the access to a trunk (here rear).

This VC trunk flap includes a PSV top panel, a PRV bottom panel and a DV flap liner.

The shutter lining DV comprises upper parts PSD and lower parts PID which extend mutually, and which can delimit a frame intended to frame a window, as illustrated without limitation in Figures 1 and 2.

The upper part PSD of the DV flap liner is intended to be rotatably mounted on the rear part of the vehicle structure.

The lower part PID of the flap lining DV comprises a rear wall PRD extended to the right and left by two lateral parts PL coming to rest on, and hide, part of a structural edge participating in the definition of the trunk.

The lower PRV panel is intended to be placed at the end (here rear) of the vehicle, contributes to the style of the latter and is intended to be glued to the lower PID part of the DV flap lining. For this purpose, the lower part PID comprises first bonding zones ZC1 which must receive glue for bonding corresponding second bonding zones ZC2 of the lower PRV panel, as illustrated in Figures 2, 4 and 5.

The PSV top panel is intended to be glued to the PSD top of the DV shutter liner. For this purpose, and although it does not appear in the figures, the upper part PSD comprises first gluing zones ZC1 which must receive glue for gluing corresponding second gluing zones ZC2 of the upper panel PSV.

As illustrated at least partially in Figures 2, 4 and 5, at least one of the first ZC1 and second ZC2 bonding zones comprises at least one protective rib NPj which is defined at the periphery of at least part of a predefined zone ZPj and suitable for preventing the entry of glue into the latter (ZPj) during gluing.

In other words, wherever glue must not penetrate into a predefined zone ZPj, a protective rib NPj is defined on at least part of the periphery of the latter (ZPj) which acts as a barrier for the glue which has been deposited in the neighboring bonding zone ZCj. Thus, there is no longer any risk of having to remove glue in a coupling zone ZCj, or even of being forced to scrap the trunk flap VC, which is advantageous from an economic point of view and from a safety point of view. pollution and discharges.

Furthermore, this anti-glue protection does not lead to an increase in the cost of the trunk flap VC, since the protective ribs NPj are an integral part of the flap lining DV by being produced by molding at the same time as the latter (DV ), or a lower GRP or upper PSV panel being made by molding at the same time as the latter (GRP or PSV).

For example, and as illustrated without limitation on the , at least two first bonding zones ZC1 and/or two second bonding zones ZC2 may respectively comprise two protective ribs NP1 (j = 1) or NP2 (j = 2) which are defined respectively at the periphery of at least parts of two remote predefined zones ZP1 or ZP2. It will be noted that in the example illustrated non-limitingly on the two first bonding zones ZC1, defined in the lower part PID of the shutter lining DV in the right and left side parts PL, each include a protective rib NP1, in order to protect two neighboring coupling zones ZC1. Here, the two ZC1 coupling zones are intended to allow the coupling of two optical units. But the number of protective ribs NPj of the DV shutter lining or a lower PRV or upper PSV panel can take any value greater than or equal to one. Likewise, the upper part PSD of the flap lining DV could include at least one protective rib NPj.

Also for example, and as illustrated non-limitingly and partially in Figures 2 and 4 and 5, first(s) ZC1 and second(s) ZC2 bonding zones may respectively comprise first(s) NP1 and second(s) NP2 protective ribs, defined at the periphery of first(s) ZP1 and second(s) ZP2 predefined zones which must be placed facing each other, and capable of being pressed against each other. This is particularly useful when the first ZP1 and second ZP2 predefined zones face each other, because this prevents the glue from penetrating into one of them (ZP1, ZP2) during its spreading.

Also for example, and as illustrated non-limitingly and partially in Figures 2 and 4 and 5, at least one predefined zone ZPj can comprise a through hole TT which is capable of being crossed by a coupling element EC capable of ensuring coupling of 'equipment on the DV shutter lining. As mentioned above, this equipment can, for example, be an optical unit. Note that the coupling element EC can, for example, be a screw. But it could also be a pawn or a clipping tab. It will also be noted that in the example illustrated non-limitingly and partially in Figures 2, 4 and 5, the first ZP1 and second ZP2 predefined zones each comprise a through hole TT which is suitable for being crossed by the coupling element EC. For example, one of these two TT through holes may have an internal thread. But a protective rib NPj may be intended to protect something other than a through hole TT in a predefined zone ZPj which must not receive glue.

Also for example, and as illustrated non-limitingly and partially in Figures 2, 4 and 5, at least one protective rib NPj can have a semi-circular shape. But other shapes can be considered, and in particular a circular or quasi-circular shape, or a U or V or even L shape, for example.

It should also be noted that the shutter lining DV can, for example, be made with each protective rib NPj by molding a plastic material, preferably rigid and resistant. The latter can, for example, be polypropylene (or PP).

Likewise, a lower PRV or upper PSV panel can, for example, be made with each protective rib NPj by molding a plastic material, preferably rigid and resistant. The latter can, for example, be polypropylene (or PP).
