DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Identical elements, by structure or by function, appearing in different figures keep, unless otherwise specified, the same references.

An electronic module 1 for a motor vehicle 2 is illustrated in FIGS. 1 to 10 according to a nonlimiting embodiment.

By motor vehicle is meant any type of motor vehicle.

As illustrated in FIG. 1, the motor vehicle 2 comprises:

- a body 20; and

- a passenger compartment 21.

The electronic module 1 is in one piece, that is to say the entire electronic module 1 is fixed to the bodywork 20 in a single block. The electronic module 1 is thus available in one piece for its attachment to the motor vehicle 2 which facilitates its installation and reduces the installation time.

As illustrated in FIG. 2, the electronic module 1 comprises:

- an electronic unit 11 adapted to be placed partly inside the motor vehicle 2 under said bodywork 20, said electronic unit 11 comprising:

- At least one secondary insert 131 comprising a secondary flat base 1310 adapted to be in contact with a secondary flat zone 208 of said bodywork 20;

- A cover 18 adapted to be disposed on said bodywork 20, said cover comprising at least one primary insert 181 adapted to be disposed substantially opposite said at least one secondary insert 131 and comprising a primary flat base 1810 adapted to be in contact with the area primary plane 207 of said bodywork 20.

As illustrated in FIGS. 1 and 2, in a nonlimiting embodiment, the electronic module 1 is an antenna module (s) and said electronic unit 11 is an antenna unit comprising at least one antenna 15. This mode non-limiting embodiment is taken in the following description.

The antenna module (s) 1 is called a shark antenna.

In a nonlimiting embodiment, the antenna unit 11 comprises:

- an upper cover 13; and

- a lower cover 14.

Said antenna 15 is in particular arranged on the upper cover 13 as described below. In a nonlimiting embodiment, it is adapted to project through an opening 200 of said bodywork

20.

In a nonlimiting embodiment illustrated in FIG. 2, the antenna module (s) 1 further comprises an antenna cover 12 adapted to pass through an opening 200 of said bodywork 20, and the antenna 15 is suitable for projecting into said antenna cover 12. This non-limiting embodiment is taken in the following description.

In a nonlimiting embodiment, the bodywork 20 is the roof of the motor vehicle 2. The roof 20 is taken as a nonlimiting example in the following description. It is described below.

• Roof 20

As illustrated in FIG. 3a and 4a, in a nonlimiting embodiment, the roof 20 comprises:

- An opening 200 through which the antenna cover 12 can pass;

- an embossing 202 which can accommodate the cover 18. The cover 18 rests on said embossing 202. The embossing 202 is also called housing;

- At least one fixing hole 201 adapted to fix the whole of the antenna module (s) 1 on the roof 20, namely the cover 18 and the antenna housing 11. A fixing screw 31 is adapted to pass through this fixing orifice 201 so as to fix the cover 18 and the antenna housing 11 together and so that the roof 20 is sandwiched between said cover 18 and the upper cover 13 of the antenna housing 11.

In a nonlimiting embodiment, the roof 20 includes three fixing holes 201 adapted to cooperate with fixing screws 31 described below, so as to obtain good fixing. Two fixing holes 201 are distributed on either side of the opening 201 and facing one another. A fixing hole 201 is disposed on the side of one end 2000 of the opening 200, the other two fixing holes 201 on the side of the opposite end 2001. Three fixing screws 31 are adapted to pass through the roof 20 respectively by these fixing holes 201.

Apart from the fixing holes 201, the roof 20 does not include any particular fixing device for fixing the cover 18 or the antenna box 11. Thus, this simplifies the production of the roof 20.

The roof 20 is curved and includes a curve 206 illustrated in Figures 3b-3d and 4b-4d.

In a first nonlimiting embodiment, the curve 206 has a radius of curvature of 5000mm along the XZ plane, and 5000mm along the YZ plane. This applies, for example, to recreational motor vehicles.

In a second nonlimiting embodiment, the curve 206 has a radius of curvature of 900mm along the XZ plane, and 900mm along the YZ plane. This applies, for example, to commercial motor vehicles.

As illustrated in FIGS. 3b-3d and 4b-4d, the roof 20 includes:

- At least one primary flat area 207 adapted to be in contact with a primary flat base 1810 of a primary insert 181. In a nonlimiting embodiment, the roof 20 comprises three primary flat areas 207.

- At least one secondary planar zone 208 adapted to be in contact with a secondary planar base 1310 of a primary insert 181. In a nonlimiting embodiment, the roof 20 comprises three secondary planar zones 208.

In a nonlimiting embodiment, the roof 20 comprises at least two primary flat zones 207 which belong to the same plane. As will be seen below, this prevents the primary insert 181 and the secondary insert 131 from being axially offset from one another. This thus facilitates the screwing of a fixing screw 31 in said primary 181 and secondary 131 inserts.

Embossing 202 includes:

- an external face 203, which faces outwards from the passenger compartment 21;

- An internal face 204, which faces the interior of the passenger compartment 21. In the embossing 202, said at least one primary flat area 207 and secondary flat area 208 are arranged.

Note that:

- A primary flat area 207 of the roof 20 belongs to the external face 203 of the embossing 202;

- a secondary flat area 208 of the roof belongs to the internal face 204 of the embossing 202.

In a first nonlimiting embodiment, the external face 203 is curved. In a second nonlimiting embodiment, the external face 203 is planar.

Figures 3a-3d and 4a-4d illustrate the roof 20 according to two non-limiting embodiments.

Ρ.Γθ ™ ipIJT_Qde of realization

The first non-limiting embodiment is illustrated in Figures 3a to 3d. In this first nonlimiting embodiment, the roof 20 comprises:

- an embossing 202 comprising an external curved face 203. Thus, the embossing 202 is curved. In a nonlimiting embodiment, it has the same curve 206 as the entire roof 20;

- a primary flat area 207. The latter is located in the embossing 202;

- a secondary flat area 208. The latter is located in the embossing 202.

The primary flat area 207 is adapted to be in contact with a primary flat base 1810 of a primary insert 181.

The secondary flat area 208 is adapted to be in contact with a secondary flat base 1310 of a secondary insert 131.

Having a planar contact on a localized plane allows flat tightening by screwing the cover 18 and the antenna housing 11 on the roof 20 via the primary insert 181 and the secondary insert 131 by means of a fixing screw. 31 (illustrated in Figure 6).

As illustrated in FIGS. 3b and 3c, the primary flat area 207 can be offset relative to the external face 203 of the embossing 202.

As illustrated in FIG. 3b, in a first nonlimiting alternative embodiment, the primary flat area 207 is arranged in a flush manner below the external face 203 of the embossing 202, namely set back from the external face 203. It forms a cavity relative to the external face 203 into which the primary insert 181 is inserted.

As illustrated in FIG. 3c, in a second nonlimiting alternative embodiment, the primary flat area 207 is arranged in a flush manner higher than the external face 203 of the embossing 202, namely projecting from the external face 203. It forms a protuberance with respect to the external face 203 on which the primary insert 181 comes to rest.

As illustrated in FIG. 3d, in a third non-limiting variant, the primary flat area 207 is arranged flush with the external face 203 of the embossing 202, namely at the same level as the external face 203.

In this first nonlimiting embodiment, the cover 18 which matches the external face 203 of the embossing 202 is curved. There is thus a flat screwing while compressing the seal 182 of the cover 18 parallel to the curve 206 of the embossing 202. The seal 182 is thus compressed uniformly.

In a nonlimiting embodiment, the roof 20 comprises three primary planar areas 207 and three secondary planar areas 208 adapted to be in contact with the primary planar base 1810 of three primary inserts 181 respectively and with the secondary planar base 1310 of three inserts secondary 131.

Two i èm e_m_o.de _d_e realization.

The second nonlimiting embodiment is illustrated in FIGS. 4a to 4d. In this second nonlimiting embodiment, the roof 20 comprises:

an embossing 202 comprising a planar external face 203. Thus, the embossing 202 is planar. Unlike the rest of the roof 20, it does not have a curve.

- a primary flat area 207. The latter is located in the embossing 202 on its external face 203;

- a secondary flat area 208. The latter is located in the embossing 202 on its internal face 204.

The primary flat area 207 is adapted to be in contact with a primary flat base 1810 of a primary insert 181.

The secondary flat area 208 is adapted to be in contact with a secondary flat base 1310 of a secondary insert 131.

Having a planar contact on a localized plane allows flat tightening by screwing the cover 18 and the antenna housing 11 on the roof 20 via the primary insert 181 and the secondary insert 131 by means of a fixing screw. 31 (illustrated in Figure 6).

As illustrated in FIG. 4b, in a first nonlimiting alternative embodiment, the primary flat area 207 is arranged flush with the external face 203 of the embossing 202, namely at the same level as the external face 203.

As illustrated in FIGS. 4c and 4d, the primary flat area 207 can be offset relative to the external face 203 of the embossing 202.

As illustrated in FIG. 4c, in a second nonlimiting alternative embodiment, the primary planar zone 207 is arranged in a flush manner above the external face 203 of the embossing 202, namely projecting from the external face 203. It forms a protuberance with respect to the external face 203 on which the primary insert 181 comes to rest.

As illustrated in FIG. 4d, in a third nonlimiting alternative embodiment, the primary flat zone 207 is arranged in a flush flush manner with the external face 203 of the embossing 202, namely set back from the external face 203. It forms a cavity with respect to the external face 203 into which the primary insert 181 is inserted.

In this second nonlimiting embodiment, the cover 18 which matches the external face 203 of the embossing 202 is flat. There is thus a flat screwing while compressing the seal 182 of the cover 18 parallel to the plane of the embossing 202, namely flat. The seal 182 is thus compressed symmetrically.

In a nonlimiting embodiment, the roof 20 comprises three primary planar areas 207 and three secondary planar areas 208 adapted to be in contact with the primary planar base 1810 of three primary inserts 181 respectively and with the secondary planar base 1310 of three inserts secondary 131.

The elements of the antenna module (s) 1 are described in detail below.

• Cover 18

The cover 18 is illustrated in FIGS. 2, 5a to 5c.

In a nonlimiting embodiment, it is made of a plastic material. It is suitable for:

- be arranged on the roof 20, more particularly in the embossing 202 of the roof 20, on its external face 203;

- cover the antenna 15. For this purpose, it comprises a housing 189 adapted to accommodate said antenna cover 12 and therefore said antenna

15.

The cover 18 comprises as illustrated in FIG. 5a:

- a base 180;

- two ends 1807; and

- two sides 1808.

As illustrated in FIG. 5a, in nonlimiting embodiments, the cover 18 further comprises:

- a seal 182. In particular its base 180 serves as a support for the seal 182;

- at least one primary insert 181.

Said at least primary insert 181 is suitable for fixing the cover 18 on the antenna housing 11, in particular on its upper cover 13, so that the roof 20 is sandwiched between said cover 18 and the antenna housing 11.

In a nonlimiting embodiment illustrated in FIG. 5a, the cover 18 comprises three primary inserts 181 for better fixing. Two are distributed on each side 1808 of the housing 189 on the side of one end 1807, the third is arranged at the end of the housing 189 on the side of the opposite end 1807.

In a nonlimiting embodiment, the cover 18 comprises a base 180 adapted to match the external face 203 of the embossing 202. Said base 180 comprises said at least one primary insert 181.

Thus, this makes it possible to compress the seal 182 parallel to said external face 203. The seal 182 is compressed uniformly. There is no loss of compression on the edges of said seal, for example as in the case where the base 180 does not match the external face 203. For example in the case where the base 180 is plane relative to to a curved external face 203, or even in the case where the base 180 comprises a curve different from the curve 206 of the external face 203.

In a first non-limiting alternative embodiment illustrated in FIG. 5b, the cover 18 comprises a curved base 180 adapted to cooperate with a curved embossing 202 of the roof 20, the external face 203 of the embossing 202 being curved.

In a second non-limiting alternative embodiment illustrated in FIG. 5c, the cover 18 comprises a flat base 180 adapted to cooperate with a plan embossing 202 of the roof 20, the external face 203 of the embossing 202 being planar.

In a first nonlimiting embodiment illustrated in FIGS. 1 and 2, the cover 18 is a protective cover. When the antenna module (s) 1 comprises an antenna cover 12, the protective cover 18 is adapted to cover said antenna cover 12. The protective cover 18 has a protective function for the antenna module ( s) 1 against the infiltration of water, dust or any other foreign body.

In a second nonlimiting embodiment not illustrated, the cover 18 is an aesthetic cover. The aesthetic cover is adapted to cover the protective cover. The aesthetic cover has an aesthetic function. In a nonlimiting embodiment, the aesthetic cover has the shape of a shark fin, the tip of the shark fin being located towards the front of the motor vehicle 2 in a nonlimiting embodiment.

O LnseÛJ2.rim_aire_1_81_

A primary insert 181 is illustrated in FIGS. 5a to 5c and 6.

Figures 5b and 5c illustrates a schematic rear view in the Y-Z plane along an axis B-B ’of two primary inserts 181 and the base 180 of the cover

18.

A primary insert 181 is adapted to cooperate with a fixing screw 31 so as to secure the assembly of the antenna module (s) 1 on the roof 20. In fact, it is adapted to be disposed substantially opposite a secondary insert 131 of the antenna housing 11 and thus allows said cover 18 to be fixed to the antenna housing 11 so as to sandwich said roof 20. To this end, a primary insert 181 is threaded.

The same fixing screw 31 is inserted into a primary insert 181 and the corresponding secondary insert 131.

In a nonlimiting embodiment, the primary insert 181 is cylindrical. In another nonlimiting embodiment, the primary insert 181 may include planar faces.

A primary insert 181 is inserted into an orifice 181 ′ of the cover 18 provided for this purpose as illustrated in FIG. 5a. It is part of the base 180 of the cover 18. In a nonlimiting embodiment, the primary insert 181 is molded into said base 180. In a nonlimiting embodiment, the primary insert 181 is metallic.

A primary insert 181 comprises a primary flat base 1810 adapted to be in contact with said primary flat area 207 of the roof 20 described above. There is thus a localized contact on plan on plan. Thus, when the cover 18 is curved to follow the curve 206 of the embossing 202, this thus avoids having a curved primary insert 181 (in particular its primary base), which is difficult to achieve. In addition, this avoids having a curved primary insert 181 which follows the curve of the cover 18, which is also difficult to achieve.

Note that the seal 182 of the cover 18 has a certain thickness. In a nonlimiting example, it includes a thickness of 1mm. This has the consequence that the external radius of curvature of the seal 182 is 5001mm relative to that of the curve 206 of the embossing 202 (more particularly of its external face 203) which is 5000mm in the nonlimiting example. taken (when the external face 203 of the embossing 202 is not flat). The radius of curvature of the seal 182 is thus slightly different from that of the curve 206 of the embossing 202, namely of the curve 206 of its external face 203. This has the consequence that if the screwing of the fixing screw 31 in the primary 181 and secondary 131 inserts is carried out perpendicular to the curve 206 of the embossing 202, this causes an axial offset (along the XY axis) between the primary insert 181 and the corresponding secondary insert 131. It will be noted that when the two primary inserts 181 are screwed perpendicularly to the curve 206 of the embossing 202, their respective primary plane base 1810 belong to two different planes which intersect with each other.

Therefore, when screwing:

- the screwing will be more difficult because the primary insert 181 and the corresponding secondary insert 131 will not be perfectly aligned;

- the seal 182 will lift partially and its compression will be non-uniform, which will result in poor sealing of the antenna module (s) 1.

To solve this problem of axial offset, in a nonlimiting embodiment, said cover 18 comprises at least two primary inserts 181 whose primary plane bases 1810 belong to the same plane P1 (illustrated in FIGS. 5b and 5c) when they are in contact with the primary flat areas 207 of said bodywork 20. Thus, this makes it possible to avoid the axial offset of the primary and secondary inserts 181 and 131. Bodywork side 20, in a non-limiting embodiment, said bodywork 20 comprises at least two primary plane areas 207 which belong to the same plane (not illustrated).

More particularly, in the case where the bodywork 20 is the roof 20, in a nonlimiting embodiment, the primary plane base 1810 of the primary insert 181 is normal to a vertical direction Z relative to the chassis of the motor vehicle 2. In this way, the fixing screw 31 is screwed into said primary insert 181 and consequently the primary insert 181 is tightened vertically relative to the chassis of the motor vehicle 2.

This allows the primary insert 181 not to be offset from the secondary insert 181 during screwing. They are well aligned before screwing and after screwing. The screwing is easy to perform.

In addition, overmolding in the cover 18 is simpler to perform than overmolding with a primary insert 181 oriented in the mold for the overmolding so that said primary plane base 1810 follows the curve 206 of the roof 20.

When the fixing screw 31 is screwed into the primary insert 181, said fixing screw 31 will pull the primary insert 181 and therefore the cover 18 towards the roof 20 so that the seal 182 compresses to ensure tightness of the antenna module (s) 1. The primary insert 181 and therefore the cover 18 thus approaches the roof 20 during screwing until there is a plane on plane contact located between the base primary plane 1810 of the primary insert 181 and the primary plane area 207 of the roof 20. It will be noted that the cover 18 has been previously positioned on the roof 20.

With a vertical screw connection with respect to the chassis of the motor vehicle 2, of the primary insert 181 on the embossing 202, the seal 182 will be compressed uniformly. It will not fold. It will not undergo a horizontal compression force (along the XY axis) as in the case of a screwing perpendicular to the curve 206 of the embossing 20 (namely of its curved external face 203) which causes a loss of compression on edges.

The seal 182 is illustrated in Figure 5a.
