Description

Motor vehicle with an optical unit provided with a hubcap docking on the optical unit housing

The present invention relates to a motor vehicle having a trim element installed docking on the housing of an optical unit.

The optical units of a motor vehicle include a housing containing a lighting device. Their front face is closed by a glass from which the light emitted by the lighting device emerges. Trim elements, for example hubcaps, are often installed, and generally have air inlet fins, which makes it possible to maintain the lighting device at a temperature preventing it from overheating, and/or to inject paint within the vehicle structure during its design. In addition to these technical aspects, the trim elements are also installed with a view to improving the styling aspects of the vehicle, and thus improving the quality perceived by users. For example, covering elements allow you to cover complex areas to be painted.

Document FR 2 946 609 proposes a system for fixing a trim element to a housing such as that of a vehicle signaling device. The fixing system comprises first fixing means ensuring that the covering element is pressed against the housing and cooperating by sliding complementary surfaces in the direction of installation. The fixing system also comprises second fixing means serving as a stop in the direction of installation. The stop ensures that the covering element is retained in a direction opposite to that of its installation. The advantage of this fixing system is to ensure the assembly of the covering element using a simple movement, thus avoiding any fixing action by screwing or welding.

Another way of installing a trim element to an optical unit is to clip the trim element onto the bumper, using clipping means.

However, and in particular when the covering element is docked with a front light housing, the technical size of the housing does not allow sufficient depth to accommodate clipping means. It is also not possible to make one or more openings capable of receiving a clipping means on the front face of the housing, because the housing of the optical device must be waterproof to protect the electrical components of the device. lighting. Therefore, in this specific case, it is not possible to stabilize the positioning of the hubcap relative to the housing of the optical unit and the integrity of the lighting device is therefore not ensured because no sealing is provided. guarantee.

The invention aims to respond to at least one of the problems or disadvantages encountered in the prior art. In particular, the invention aims to propose a motor vehicle with an optical unit where the interface between a hubcap and the housing is possible when the hubcap and the housing are docked relative to each other.

For this purpose and according to a first aspect, the invention relates to a motor vehicle with a front facade and/or a rear facade, the front facade and/or the rear facade comprising a bumper skin delimiting a housing, the housing having at least one optical unit with a housing enclosing one or more light devices, the housing showing a first wall, the housing further comprising at least one trim extending from the first wall of the housing; the motor vehicle is remarkable in that the first wall comprises at least one fixing tab with a first portion fixed at the level of the bumper skin, and a second portion fixed at the level of the hubcap.

As will be understood from reading the definition which has just been given, the invention proposes a motor vehicle comprising at least one optical unit with a hubcap placed on the side of the housing of the optical unit, in which the lack space does not prevent the hubcap and the housing from interfacing. The arrangement between the hubcap and the box which results from the configuration according to the invention is a stable and waterproof arrangement. Indeed, the wall from which the hubcap extends includes one or more fixing lugs allowing both to fix the housing on the bumper skin and to attach the hubcap to the housing.

For example, the first portion and the second portion are superimposed.

For example, the first portion comprises a first orifice with a first direction of insertion, and the second portion comprises a second orifice with a second direction of insertion inclined relative to the first direction of insertion.

Advantageously, the hubcap shows an internal face, said internal face of the hubcap comprising a projecting part and the second portion fixed at the level of the hubcap is fixed on the hubcap using a fixing means cooperating with said second portion and with the projecting part. Preferably, said fixing means cooperating with said second portion and with the projecting part is a clipping means. For example, said fixing means came integrally with said hubcap. Preferably, said hubcap is made of plastic material.

Advantageously, the first portion fixed at the level of the bumper skin is fixed on the bumper skin. For example, the first portion fixed at the level of the bumper skin is fixed to the bumper skin using a screw.

Advantageously, the bumper skin shows an internal face, said internal face being covered by a bumper reinforcement, and the first portion fixed at the level of the bumper skin is fixed on said bumper reinforcement. For example, the bumper skin shows an internal face, said internal face being covered by a bumper reinforcement, and the first portion fixed at the level of the bumper skin is fixed on said bumper reinforcement using a screw.

Advantageously, the first wall of the housing is a side wall located on the side of the center of the front facade and/or the rear facade. Preferably, the housing shows a second wall located opposite the first wall, and the second wall is fixed at the level of the bumper skin, for example using a screw. For example, the bumper skin shows an internal face, said internal face being covered by a bumper reinforcement, and the second wall is fixed to said bumper reinforcement, for example using a screw.

Advantageously, said hubcap comprises at least one fixing tab and the bumper skin shows an opening corresponding to said at least one fixing tab of the hubcap, the latter being arranged within said corresponding opening. Preferably, the hubcap shows a first side arranged along the first wall of the housing and at least one second side, and the fixing lug(s) are located on said second side.

Advantageously, said hubcap comprises at least one reinforcing rib.

For example, said hubcap comprises at least one reinforcing rib extending transversely from the first wall.

The invention will be well understood and other aspects and advantages will appear clearly on reading the description which follows, given by way of example with reference to the appended drawing boards in which:

In the remainder of the description, the term “include” is synonymous with “include” and is not restrictive in that it authorizes the presence of other elements in the vehicle to which it refers. It is understood that the term “understand” includes the terms “consist of”. The terms “external” and “internal” will respectively designate what is oriented towards the exterior of the vehicle and towards the interior of the vehicle.

In this description, the term “longitudinal”, the term “longitudinal”, the term “transverse”, and the term “transversely” are used according to the reference of the vehicle, in the assembly configuration. The term “longitudinal” corresponds to the main direction of movement of the vehicle. The term “transverse” corresponds to a direction perpendicular to the main direction of movement of the vehicle. The term “front” refers to the main direction of movement of the vehicle. The term “rear” refers to the opposite of the front of the vehicle.

The invention relates to a motor vehicle where the trim of an optical unit is mounted docking with the housing of said optical unit. Thus, the motor vehicle comprises a front facade and/or a rear facade, the front facade and/or the rear facade comprising a bumper skin 1 delimiting a housing, the housing having at least one optical unit with a housing 3 enclosing one or more light devices 5, the housing showing a first wall 7, the housing further comprising at least one hubcap 9 extending from the first wall 7 of the housing. For example, the hubcap 9 extends between the first wall 7 of the housing and the bumper skin 1 facing said first wall 7 and/or, the hubcap 9 extends from the first wall 7 of the housing up to the bumper skin 1 facing said first wall 7.

The hubcap 9 and/or the housing 3 are preferably made of plastic material.

As shown in Figures 1 and 2, the motor vehicle according to the invention is remarkable in that the first wall 7 comprises at least one fixing bracket 11 with a first portion 13 fixed at the level of the bumper skin 1, and a second portion 15 fixed at the level of the hubcap 9. In this way, the housing 3 is attached both at the level of the bumper skin 1 and at the hubcap 9.

As the wall of the housing (i.e., the first wall 7) from which the hubcap 9 extends comprises at least one fixing lug 11 allowing not only to fix the housing 3 on the bumper skin 1 but also to attach the hubcap 9 to the housing 3, this makes it possible to optimize the interfacing of the hubcap 9 with the housing 3 of the optical unit despite the restricted environment which occurs in this area. The hubcap 9, thus attached at the level of the first wall 7, improves the style of the vehicle, without hindering the front face of the housing 3 of the optical unit, which also makes it possible to maintain the intrinsic sealing of the housing 3 of the optical unit.

The first portion 13 and the second portion 15 can be superimposed. Generally, in the case where the invention is carried out at the level of the front facade of the vehicle, the first portion 13 fixed at the level of the bumper skin 1 is preferably rearward in relation to the second portion 15 fixed at the level of the hubcap 9, so that the hubcap 9 is more easily accessible by a user placed in front of the front facade. Conversely, in the case where the invention is carried out at the level of the rear facade of the vehicle, the first portion 13 fixed at the level of the bumper skin 1 is preferably forward in relation to the second portion 15 fixed at the level of the hubcap 9, so that the hubcap 9 is more easily accessible by a user placed behind the rear facade.

Preferably, the invention is implemented both on the front facade and on the rear facade of the motor vehicle.

As shown on the , the first portion 13 fixed at the level of the bumper skin 1 advantageously comprises a first orifice 17 with a first direction of insertion. The first orifice 17 is generally circular in shape and shows a thread. The second portion 15 fixed at the level of the hubcap 9 advantageously comprises a second orifice 19 with a second direction of insertion inclined relative to the first direction of insertion. The second orifice 19 is generally square or rectangular in shape.

There is a sectional view of the interface between hubcap 9 and housing 3 of the optical unit. Thus, advantageously, the hubcap 9 comprises a projecting part 35 on its internal face, as also shown on the , and the second portion 15 of the fixing tab fixed at the level of the hubcap 9 is fixed on the hubcap 9 using a fixing means cooperating with both the second portion 15 and the projecting part 35 , such as for example a clipping means 21. The fixing means cooperating with the second portion 15 and with the projecting part 35 has the advantage that it is not necessary to fix the hubcap 9 to the housing 3 by welding and /or screwing. The fixing means can be integral with the hubcap 9. Preferably, the hubcap 9 is made of plastic material. The projecting part 35 advantageously comes from one piece with the hubcap 9.

The hubcap 9, represented in , also shows several fixing lugs 29. The is a sectional view, where a fixing tab 29 of the hubcap 9 is inserted into a corresponding opening 31 presented by the bumper skin 1. Preferably, the hubcap 9 shows a first side 37 arranged along the first wall 7 of the housing and at least one second side (39, 41, 43), and the fixing lug(s) 29 are located on said second side (39, 41, 43). The presence of one or more fixing lugs 29 on the sides of the hubcap which do not run along the first wall 7 of the optical unit housing makes it possible to hold the hubcap 9 pressed against the bumper skin 1 when the hubcap is held by the second portion 15 of the housing fixing tab.

For example, the hubcap has four sides. One of the four sides is arranged along the first wall 7 of the housing, and at least one of the three remaining sides shows at least one fixing tab 29. More preferably, at least two of the three remaining sides show at least one fixing tab 29, as shown on the .

For example, the hubcap shows a first side 37 arranged along the first wall 7 of the housing, a second side 41 located opposite the first side 37, an upper side 39, and a lower side 43. The hubcap can then show one or more fixing tabs 29 on the second side 41 and/or one or more fixing tabs 29 on the lower side 43. As shown in the , the hubcap can show one or more fixing lugs 29 on the second side 41 and one or more fixing lugs 29 on the lower side 43.

Advantageously, the hubcap 9 comprises at least one reinforcing rib 33 extending transversely from the first wall 7 of the housing. The presence of at least one reinforcing rib 33 makes it possible to guarantee sufficient rigidity of the hubcap 9, mainly in the areas which are not attached.

Figures 6 and 7 are sectional views of the fixing tab 11 of the housing 3 at the level of the first portion 13 fixed at the level of the bumper skin 1. The first portion 13 can be fixed on the bumper skin 1, for example by means of a screw 25 ( ). The first portion 13 can also be fixed to a bumper reinforcement 23, for example by means of a screw 25, said bumper reinforcement 23 covering the internal face of the bumper skin 1 ( ).

The first wall 7 of the housing is advantageously a side wall located on the side of the center of the front facade and/or the rear facade. Preferably, the housing 3 shows a second wall 27 located opposite the first wall 7, and the second wall 27 is fixed at the level of the bumper skin 1, for example by means of a screw. The second wall 27 can therefore be fixed on the bumper skin 1 or, when a bumper reinforcement 23 covers the internal face of the bumper skin 1, on said bumper reinforcement 23.
