Description

Title of the invention: ASSEMBLED SYSTEM OF PARTS AND DISPLAY COMBINATION, WITH SPECIAL ASSEMBLY ALLOWING PRECISE DOCKING OF AN EDGE OF THE DISPLAY COMBINATION Technical field of the invention

[0001] The invention relates to systems comprising a display unit and at least three assembled parts. State of the art

[0002] In certain technical fields, systems are used comprising a display unit and at least three parts which are assembled together. This is the case, for example, in certain vehicles, possibly of the automobile type, in particular in a dashboard.

[0003] Some of these systems include:

[0004] - a first piece,

[0005] - a display unit comprising a first edge (for example upper) and so fixed lidarized to the first part,

[0006] - a second part comprising a second front edge provided with first faces external and internal and coupled to the first part, and

[0007] - a third part fixedly secured to the second front edge and comprising a third front edge projecting in front of this second front edge and having a second internal face placed opposite the first edge (for example above the latter).

[0008] As an illustrative example, when the system is a dashboard of a vehicle, the first part may be a support part (mainly dedicated to fixing the display unit), the second part may be an upper reinforcement part (possibly provided with a covering skin), and the third part may be a trim fixedly secured to the second front edge of the second part.

[0009] When the display unit is assembled before the third part, it is possible to shape the third front edge of the latter so that it masks the first edge of the display unit, so as to obtain precise and high-quality docking.

[0010] However, in certain systems it may be necessary to assemble the third part after the display unit, for example when this third part is very long and has a very small section, and therefore the first edge of the display unit becomes visible. This results in an imprecise docking which may vary due to manufacturing dimensional dispersions and the dis variations in the relative positions of the system parts. Thus, it may happen that the empty space (or play) between the third part and the first edge of the display unit reveals a small portion of a technical part, which is unsightly and often considered by users of the system as an assembly defect or a design defect that detracts from the impression of quality of this system.

[0011] Furthermore, when the system is a dashboard, the presence of the third front edge of the third part makes it difficult to install the display unit when the steering column is already installed, which is almost always the case.

[0012] The invention therefore aims in particular to improve the situation. Presentation of the invention

[0013] For this purpose, it proposes in particular an assembled system comprising:

[0014] - a first piece,

[0015] - a display unit comprising a first edge and fixedly secured to the first piece,

[0016] - a second part comprising a second front edge provided with first faces external and internal and coupled to the first part, and

[0017] - a third part fixedly secured to the first external face of the second front edge and comprising a third front edge projecting in front of this second front edge and having a second inner face.

[0018] This assembled system is characterized by the fact that the third front edge is curved so that its second internal face defines with the first internal face a first housing in which the first edge is installed and masked after a combination of translations in at least two different directions and at least one rotation of the display unit in an installation phase before joining.

[0019] Thanks to this combination of translations and rotation(s), the first edge of the display unit can now be housed in the first housing of the third curved front edge of the third part (installed before it) to mask it and thus give an impression of precise and quality docking between the display unit and the third part.

[0020] The system assembled according to the invention may include other characteristics which may be taken separately or in combination, and in particular:

[0021] - its display unit may comprise in a rear part at least one first protuberance, and its first part may comprise at least one opening in which the corresponding first protuberance is partially installed during the installation phase so that the latter is positioned in a first predefined direction;

[0022] - in the presence of the first option, the rear part of the display unit can comprise two first distant protrusions, and the first part may comprise two distant openings and in which the corresponding first protrusions are partially and respectively installed during the installation phase;

[0023] - also in the presence of the first option, each opening can comprise a beveled guide edge, and each first protrusion may comprise a beveled guide face so as to bear and slide on this guide edge during the installation phase;

[0024] - also in the presence of the first option, the rear part of the handset display may comprise a second protrusion, and the first part may comprise at least one second housing in which this second protrusion is partially installed during the installation phase in order to be positioned in a second predefined direction which is perpendicular to the first predefined direction;

[0025] - the installation phase may comprise a first translation following a first direction, followed by a first rotation, followed by a second translation in a second direction different from this first direction, followed by a third translation in a third direction different from the first and second directions, followed by a second rotation, followed by a fourth translation in a fourth direction different from the first, second and third directions;

[0026] - the first edge of the display unit can be installed in front of the second face internal at a distance which is between 1.8 mm and 2.2 mm;

[0027] - the second front edge of the second part can hide the first edge of the display handset at a distance that is between 1.5 mm and 2 mm;

[0028] - it can constitute a dashboard suitable for equipping a vehicle and in which the second piece is an upper reinforcement piece and the third piece is a hubcap.

[0029] The invention also proposes a vehicle, possibly of the automobile type, and comprising at least one assembled system of the type presented above. Brief description of the figures

Detailed description of the invention

[0040] The invention aims in particular to propose an assembled system SA comprising at least three parts PI, P2 and P3 and a display unit CA whose particular assembly allows precise docking and masking of a first edge B1 which it comprises.

[0041] In the following, it is considered, by way of non-limiting example, that the assembled system SA is intended to equip a vehicle of the automobile type, such as for example a car. But the invention is not limited to this application. Indeed, a system assembled SA can equip any vehicle (land, sea (or river), or air), any device (possibly household appliances), any installation (including industrial), or any building (public or private).

[0042] Furthermore, it is considered in the following, by way of non-limiting example, that the assembled system SA is a dashboard of a motor vehicle. But the assembled system SA could be, or could be part of, other equipment of a vehicle, such as for example a console or a seat.

[0043] In Figures 1 to 9, the direction X is intended to be parallel to the longitudinal direction of the vehicle V, which is substantially parallel to the lateral (or longitudinal) sides comprising the side doors, the direction Y is intended to be parallel to the transverse direction of the vehicle V, which is perpendicular to the longitudinal direction X, and the direction Z is intended to be parallel to the vertical direction of the vehicle V, which is perpendicular to the longitudinal directions X and transverse directions Y.

[0044] Furthermore, in what follows and what precedes the notions of "front" and "rear" are used with reference to the front passengers of the vehicle V. Consequently, a front face of an element (or of a part) is intended to be oriented towards the front passengers of the vehicle V (and therefore towards the rear end of the latter (V)), while a rear face of this element (or part) is intended to be oriented opposite to the front passengers of the vehicle V (and therefore towards the front end of the latter (V)).

[0045] Figures 1 and 5 to 8 schematically illustrate, at least partially, an example of an embodiment of an assembled system SA according to the invention, here constituting a dashboard SA installed in a front part of a passenger compartment of a vehicle V.

[0046] As illustrated at least partially in Figures 1 to 4, an assembled system SA, according to the invention, comprises a display unit CA and at least first PI, second P2 and third P3 parts assembled together.

[0047] As indicated above, the assembled system SA is here a dashboard of a motor vehicle V, and it is considered in the following, by way of non-limiting example, that the first part PI is a support part (mainly dedicated to the fixing of the display unit CA), the second part P2 is an upper reinforcement part (possibly provided with a trim skin PH), and the third part P3 is a trim fixedly secured to a second front edge BV2 of the second part P2. But the first PI, second P2 and third P3 parts of the assembled system SA could be different from those mentioned in the previous sentence.

[0048] Here, the display unit CA is dedicated to the driver of the vehicle V (and therefore constitutes at least part of a dashboard). Furthermore, this display unit CA comprises in particular a window GC fixedly secured to a housing BC (rear) and (here) placed opposite the front passengers of the vehicle V. This housing BC is fixedly secured to the first part PI, for example by screwing using screws VF passing through first through holes TT1 defined in the housing BC (see [Fig.5]) and second through holes TT2 defined in the first part PI and possibly threaded (see [Fig.4]). It will be noted that in the example illustrated non-limitingly in [Fig.4] the second through holes TT2 are defined in parts which are plastic inserts added in holes of the first part PI (but this is not obligatory). It will also be noted that in the example illustrated non-limitingly in figures 4 and 5 the housing BC comprises four first through holes TT1 and the first part PI comprises four second through holes TT2. But the number of first through holes TT1, like the number of second through holes TT2, can take any value greater than or equal to two.The screwing allows very precise positioning of the display unit CA in relation to the first part PI, here following the longitudinal direction X.

[0049] In addition, and as illustrated in Figures 2 and 3, this display unit CA comprises a first edge Bl, here upper and forming part of the glass GC.

[0050] As illustrated in Figures 2 and 3, the second part P2 comprises a second front edge BV2 which is provided with a first external face FE2 (here facing upwards) and a first internal face FI2 (here facing downwards). Furthermore, this second part P2 is coupled to the first part PI (directly or indirectly).

[0051] As illustrated at least partially in Figures 1 to 4, the third part P3 is fixedly secured to the first external face FE2 of the second front edge BV2 of the second part P2, and comprises a third front edge BV3 which projects in front of this second front edge BV2 (and therefore here towards the front passengers and the rear of the vehicle V). For example, the fixed securing of the third part P3 to the second front edge BV2 of the second part P2 can be done by gluing and / or by ultrasonic welding.

[0052] Furthermore, this third front edge BV3 has a second internal face FI3, opposite its external face (here oriented towards the interior of the passenger compartment of the vehicle V).

[0053] Furthermore, and as illustrated in Figures 2 and 3, this third front edge BV3 is curved so that its second internal face FI3 defines with the first internal face FI2 of the second part P2 a first open housing L1. The first edge Bl is finally installed and masked in this first housing L1 after a combination of translations tj following at least two different directions and at least one rotation rk of the display unit CA in an installation phase carried out before its fixed attachment to the first part PI (for example by screwing). An example of a combination of translations tj and rotations rk applied to the display unit CA to install it in a final position p5 (immobilization) relative to the first PI and third p3 parts is illustrated non-limitingly in [Fig.9].

[0054] It will be understood that thanks to this combination of translations tj and rotation(s) rk it is now possible to house the first edge B1 of the display unit CA in the first housing L1 of the third curved front edge BV3 of the third part P3 (previously secured to the second part P2), to mask it and thus give an impression of precise and quality docking between the display unit CA and the third part P3. Furthermore, this docking, resulting from the assembly of the covered display unit CA after the assembly of the third covering part P3, prevents one from seeing what is behind the third front edge BV3, and in particular any technical part, thus reinforcing the impression of quality of the vehicle V.This makes it possible to take into account an assembly constraint of the assembled system SA (here a dashboard), namely the fact that the third part P3 is a very long part with a very small section that cannot be assembled alone after assembling the display unit CA.

[0055] For example, and as illustrated non-limitingly and at least partially in Figures 5 to 7 and 9, the display unit CA may comprise in a rear part PRC at least one first protuberance PCI. In this case, the first part PI may comprise at least one opening OP in which the corresponding first protuberance PCI is partially installed during the installation phase of the display unit CA so that this first protuberance PCI (and therefore also the display unit CA) is positioned (or wedged) in a first predefined direction (here the vertical direction Z).

[0056] It will be understood in fact that once the (each) first protuberance PCI is partially installed through the corresponding opening OP, the part (here lower) of the housing BC of the display unit CA is advantageously wedged (here vertically) which guarantees part of its final positioning. It then only remains possibly to complete the positioning of the first edge B1 in the first housing L1 by a very slight rotation forwards or backwards before proceeding to secure the housing BC to the first part PI (here by screwing the screws via the first TT1 and second TT2 through holes).

[0057] It will be noted that during the installation phase, the first FI2 and second FI3 internal faces (which delimit the first housing L1) can allow the support and / or the guidance of the first edge B1 during the last translation(s) tj and rotation(s) rk of the combination to obtain the placement of the display unit CA in its final position p5 (illustrated in figures 7 and 9).

[0058] Preferably, and as illustrated non-limitingly and at least partially in Figures 4 and 5, the rear part PRC of the display handset CA (and more precisely of its housing BC) comprises two first distant protrusions PCI, and the first part PI comprises two distant openings OP in which are installed by itially and respectively the corresponding first PCI protrusions during the installation phase. This prevents the CA display unit from being slightly inclined compared to its desired final position. But one could consider having only one first PCI protrusion associated with a single OP opening.

[0059] Also for example, and as illustrated non-limitingly and at least partially in Figures 4 to 7 and 9, each opening OP may comprise a beveled guide edge BG, and each first protrusion PCI may comprise a beveled guide face FG so as to rest and slide on the corresponding guide edge BG during the installation phase. This arrangement makes it possible to significantly facilitate the passage of each first protrusion PCI through the corresponding opening OP during a translation tj or a rotation rk.

[0060] It will be noted, as illustrated non-limitingly and at least partially in Figures 6 to 9, that each guide face FG is preferably followed by a support face FA (here lower) which allows the support of its first protuberance PCI on the end (here upper) of the guide edge BG of the corresponding opening OP, after the guide face FG has passed beyond this end. This allows the display unit CA to be properly wedged (here in the vertical direction Z).

[0061] It will also be noted that each first protrusion PCI can be an integral part of the BC housing, in particular when the latter (BC) is produced by molding a plastic material.

[0062] Also for example, and as illustrated non-limitingly and at least partially in Figures 4, 5 and 8, the rear part PRC of the display unit CA (and more precisely of its housing BC) may also comprise a second protuberance PC2. In this case, the first part PI may comprise at least a second housing L2 in which the second protuberance PC2 is partially installed during the installation phase in order to be positioned in a second predefined direction (here the transverse direction Y) perpendicular to the first predefined direction (here the longitudinal direction X). This makes it possible to correctly position the display unit CA (here in the longitudinal direction Y).

[0063] Preferably, the second protuberance PC2 is arranged so as to be housed in the associated second housing L2 before each first protuberance PCI begins to pass through the corresponding opening OP. This in fact makes it possible to guarantee that each first protuberance PCI will be correctly placed opposite the corresponding opening OP. For this purpose, the extension of the second protuberance PC2 along (here) the longitudinal direction X is greater than that of the (each) first protuberance PCI along (here) this longitudinal direction X.

[0064] It will be noted that the second protuberance PC2 can be an integral part of the housing BC, in particular when the latter (BC) is produced by molding a material plastic.

[0065] Also for example, and as illustrated non-limitingly in [Fig. 3], the first edge B1 of the display unit CA can be installed in front of the second internal face FI3 of the third front edge BV3 of the third part P3 at a distance (here substantially longitudinal (direction X)) which is between 1.8 mm and 2.2 mm. As an illustrative example, this distance (here substantially longitudinal) can be equal to 2 mm. But other values ​​can be envisaged for this distance (here substantially longitudinal). This makes it possible to obtain a functional clearance (here substantially longitudinal) which is entirely acceptable, and in particular makes it possible to take into account the dimensional dispersions of manufacture and the dispersions of the relative positions of the different parts concerned of the assembled system SA.

[0066] Also for example, and as illustrated non-limitingly in [Fig. 3], the second front edge BV2 of the second part P2 can mask the first edge B1 of the display unit CA over a distance (here substantially vertical (Z direction)) which is between 1.5 mm and 2 mm. As an illustrative example, this distance (here substantially vertical) can be equal to 1.7 mm. But other values ​​can be envisaged for this distance (here substantially vertical). This makes it possible to obtain sufficient coverage of the first edge B1 giving an impression of zero (vertical) play.

[0067] Also for example, and as illustrated non-limitingly in [Fig. 3], the first edge B1 of the display unit CA can be installed in front of the first internal face FI2 of the second front edge BV2 of the second part P2 at a distance which is between 2.5 mm and 3.5 mm. As an illustrative example, this distance can be equal to 3 mm. But other values ​​can be envisaged for this distance. This makes it possible to obtain a completely acceptable internal clearance, and in particular to take into account the dimensional dispersions of manufacture and the dispersions of the relative positions of the different parts concerned of the assembled system SA.

[0068] Also for example, and as illustrated non-limitingly in [Fig.9], the installation phase of the CA display unit may comprise:

[0069] - a first translation tl (from an initial position pO to a position in intermediate pl) following a first direction (here diagonally downwards so that each first PCI protuberance approaches the previously installed steering column),

[0070] - followed by a first rotation rl (here from the first edge B1 downwards and the first piece Pl (to reach an intermediate position p2)),

[0071] - followed by a second translation t2 (to an intermediate position p3) following a second direction different from the first direction (here slightly downwards so that the first edge B1 passes under the free end of the third front edge BV3),

[0072] - followed by a third translation t3 (to an intermediate position p4) following a third direction different from the first and second directions (here upwards and slightly obliquely towards the rear of the vehicle V so that the guide face FG of each first protuberance PCI reaches the level of the guide edge BG of the corresponding opening OP of the first part PI),

[0073] - followed by a second rotation r2 (here from the first edge B1 upwards and backwards to facilitate the start of the crossing of each first PCI protrusion through the corresponding OP opening of the first PI part),

[0074] - followed by a fourth translation t4 (to a final position p5) following a fourth direction different from the first, second and third directions (here upwards and slightly obliquely towards the front of the vehicle V so that the guide face FG of each first protrusion PCI passes beyond the corresponding opening OP of the first part PI and the support face FA of each first protrusion PCI is supported on the upper end of the guide edge BG concerned).
