Description

Title of the invention: MOTOR VEHICLE COMPRISING A HANDLE LIGHT EQUIPPED WITH A LIGHT GUIDE AND AN RGB CONNECTOR, AND A METHOD BASED ON SUCH A VEHICLE

[0001] The invention relates to the field of door handles for motor vehicles, comprising a lighting device.

[0002] In this field, US patent 6550946B2 describes an LED lighting system for an interior door handle with a mounting mechanism by stacking and clip fastening.

[0003] Unfortunately, this system is not entirely satisfactory because the lighting system is sensitive to vibrations, particularly when doors are slammed shut. These vibrations can cause unwanted noise due to faulty electrical connections in the lighting system caused by these slamming noises.

[0004] An objective of the present invention is to remedy the defects of the prior art, and in particular to offer an optimized interface for the implantation of a lighting device for an interior door handle with the aim of withstanding door slamming and guaranteeing the absence of parasitic noises under conditions of use.

[0005] To achieve this objective, the invention proposes a motor vehicle comprising a door equipped with a handle system, the handle system comprising: - a handle lining which includes a concave section, a connecting structure away from the concave section, and at least one opening into the concave section; - a handle lever extending at least partially along the concave section; characterized in that the handle system further comprises a lighting device which includes: - a light source equipped with a connection module connected to the connection structure; - a light diffuser positioned at said orifice to illuminate the concave section; and - a tubular light guide extending between the light source and the light diffuser.

[0006] Advantageously, the invention provides a lighting device comprising a source at a given location at a distance from the concave section, and a reinforcement of the source's attachment. The light diffuser is arranged in the concave section by being Oriented vertically downwards. This helps to limit the effects of vibrations from slamming doors on the light source.

[0007] In particular, the rib system of a variant makes it possible to eliminate any vibration on the light emission housing associated with a light guide with a mounting groove system in opposition to the slamming forces, associated with a crush rib for holding in position in the groove.

[0008] Thanks to a simplified assembly (compression mounting) without clips and by rib clamping, the invention allows: - to optimize the interface for installing the lighting device by ensuring the best compactness of the assembly (handle and light) and keeping the volume of the finger insertion bowl as large as possible; - to guarantee that the assembly can withstand the forces of a door slamming; - to guarantee the absence of extraneous noise under user conditions; - to ensure the guidance and clipping of the door harness connector without breaking it.

[0009] Preferably, the lining further includes a light diffuser fixing structure.

[0010] This allows the light diffuser to be kept in place in the concave section.

[0011] Preferably, the orifice forms the fixing structure of the light diffuser.

[0012] This allows the light diffuser to be fixed in the orifice.

[0013] Preferably, the connection module is an RGB optical module.

[0014] This simplifies the connection of the lighting device.

[0015] Preferably, the lining includes at least one notch allowing the light guide to pass through.

[0016] This allows space to be provided for putting the light guide in place in the lining.

[0017] Preferably, the connection structure includes ribs blocking the light source in at least one direction.

[0018] This allows the light source to remain operational despite impacts on the doors.

[0019] The invention further relates to a method for manufacturing a motor vehicle according to the invention, comprising the following steps: - a step of setting up the lining equipped with the lever; - a step of connecting the connection module to the connection structure; - a step of setting up the light diffuser at the level of the orifice.

[0020] According to one variant, the step of placing the light diffuser at the orifice includes fixing the light diffuser.

[0021] The invention will be further detailed by describing non-limiting embodiments, and based on the accompanying figures illustrating variants of the invention, including: - [Fig.1] schematically illustrates a front view and a rear view of the lining of a handle of a motor vehicle according to a preferred embodiment of the invention; - [Fig.2] schematically illustrates two side views of a motor vehicle lighting device according to the preferred embodiment; - [Fig.3] schematically illustrates a connection structure of the lining of [Fig.1]; - [Fig.4] schematically illustrates a rear view of an assembly of the lighting device of [Fig.2] in the lining of [Fig.1]; - [Fig.5] schematically illustrates a top view of the assembly of [Fig.4].

[0022] The invention is described with reference to a frame of reference in space (illustrated in [Fig.3]) comprising a front-rear axis X along a direction of movement of the vehicle; a lateral axis Y perpendicular to the front-rear axis X, and a vertical axis Z perpendicular to the front-rear axis X and to the lateral axis Y.

[0023] The device involved in this invention is the door handle (interior door control / IOC) integrated into the door panel trim. Said handle is fixed to the door lining D (also called "sheet metal").

[0024] The invention proposes to implement a lighting device with a connection module C (here in RGB), a light guide G and a light diffuser E. The lighting device is illustrated in [Fig.2].

[0025] The handle without lighting device is illustrated in [Fig.1]. It includes said lining D (or handle housing) on ​​which a handle lever L is fixed.

[0026] According to the invention, the lining D comprises a connection receptacle S receiving the connection piece (connection module M) of the lighting device. A light source SL is connected to this connection module M and to the light guide G.

[0027] The invention relates in particular to the design of the interface for integrating this lighting device: it includes a chosen arrangement of ribs NI, N3 to block possible travel (noise inducers) in X and Z between the RGB module and the reverse side of the handle. These ribs are illustrated in [Fig.3].

[0028] Lower ribs N2 can serve as slides to guide and correctly mount the door harness connector which clips into the connector of the RGB M module (physical tests without these ribs result in breakage of the harness connector).

[0029] The small lower rib N2 and the upper corner rib N3 allow the RGB M module to be held in position when the two connectors are clipped.

[0030] The lining D includes a notch EG and sufficient clearance on the reverse of the handle to allow mounting of the light guide G.

[0031] The light diffuser E is mounted on top of the lining D above the handle concavity C to illuminate it. In particular, mounting tabs are preferably provided on at least two opposite edges of the diffuser, and cooperating structures may be provided on at least two corresponding opposite edges of the opening. This configuration is illustrated in [Fig. 5].

[0032] In the preferred variant, the Y-lock is ensured with this system because the slamming of the doors induces a translation of the handle from the outside to the inside of the passenger compartment.

[0033] Other advantages of the invention include, in particular: - the fact that there is no need to screw the system together, which reduces assembly time; - the possibility of having the same handle with and without light, which implies a reduction in diversity; - the possibility of guaranteeing the guidance and clipping of the door harness connector without breaking it.

[0034] The invention further relates to a method of manufacturing a motor vehicle as described above.

[0035] The process includes steps for setting up the elements described above, and fixing them.
