Description

Light module with light guide having vibration-proof fasteners
Technical Field
The technical field of the invention belongs to the technical field of light modules for light guides of motor vehicles.
The invention relates in particular to a vibration-proof fastening device for such light guides.
Background
Some light modules have at least one light guide for guiding and transmitting light generated by a light source such as a Light Emitting Diode (LED).
These light modules are mounted on motor vehicles and are therefore subject to vibrations. These vibrations may cause the light guide to move and then no longer be able to perform its function, especially from a photometric point of view.
An optical module is known, which comprises two fastening means: the first is constituted by a clamp holding one end of the light guide and the second has V-shaped capturing teeth which retain the second end of the light guide.
However, this solution is unsatisfactory because the clamp is bulky and the V-shaped catch compromises the optical function of the light guide. The light guide is poorly vibration-resistant, which may lead to dust entering between the light guide and its support. It is also not optimized in terms of process, since the second end of each light guide needs to be inserted into a fixture separately, which is a great limitation for assembly.
Disclosure of Invention
The present invention provides a solution to the above-mentioned problems in a way that enables a better fastening of the light guide, thus allowing said light guide to withstand vibrations better and allowing easier assembly.
One aspect of the invention relates to a motor vehicle lighting module comprising:
at least one light guide extending longitudinally in an extension direction between a first end and a second end,
-a holding portion provided at the second end, and
-a support portion for the light guide.
The support portion includes:
a support element extending longitudinally in an extension direction between a first edge at the first end and a second edge at the second end, on which the upper surface of the light guide and the bottom of the support portion are positioned, extending vertically, and comprising lateral surfaces,
-a positioning device having a length L 0 Longitudinally extending in the extending direction from a proximal end facing the first edge towards a distal end located at a distance from the second edge and protruding from the lateral surface in a direction transverse to the extending direction, and vertically extending in the extending direction between a lower end facing the bottom of the support portion and an upper end, the upper end at the distal end being closer to the first end of the light guide than the lower end at the distal end, such that the distal end forms a first inclined surface.
The holding portion includes a second inclined surface having the same inclination as the first inclined surface, and a length L of the light guide between the second inclined surface and the first end is smaller than a length L of the positioning means before the light guide and the holding portion are assembled on the supporting portion 0 。
The second inclined surface is configured to slide on the first inclined surface during assembly of the light guide with the holding portion on the supporting portion so as to elongate the light guide until the light guide is located on the upper surface of the supporting member.
The light guide may be coupled to the support portion via the holding portion and via the cooperation of the first inclined surface and the second inclined surface. In addition, the cooperation of the inclined surfaces makes it possible to stretch the light guide. An inclined surface is located in place on the support portion and deforms when the light guide is locked in place. In particular, in the case of light guidesDuring fitting on the support portion, the first inclined surface is in contact with the second inclined surface, and the second inclined surface slides along the first inclined surface, so that the light guide can be stretched. The length of the light guide is thus extended and adapted to the length of the positioning means of the support portion. In particular, the length L of the light guide measured between the second inclined surface and the first end of the holding portion becomes equal to the length L of the positioning means 0 The same applies. Thus, the light guide is in contact with the support portion. This deformation of the light guide makes it possible to press the light guide against the support portion and in particular against the upper surface of the support element. Such pressing enables the light guide to avoid any movement and any vibrations, thereby better withstanding the vibrations.
Furthermore, the first inclined surface forms a retaining means for the holding means and a stopping means for the light guide in the extending direction, so that it is possible to strengthen the holding of the light guide in place and its ability to withstand vibrations.
Furthermore, such fastening makes it possible to manufacture light modules that are small in volume.
Advantageously, the light module comprises a plurality of light guides held together by the holding portion, and the support portion has a support element and a positioning means associated with each light guide, the holding portion having a second inclined face associated with the first inclined face of each positioning means. Accordingly, the holding portion and the supporting portion are shared between the plurality of light guides, and thus the fitting of the light guides on the supporting portion can be simultaneously achieved, thereby simplifying the assembly process. Furthermore, unlike the prior art, there is no need to align each light guide in a hole.
Advantageously, the support element and the positioning means are connected by the bottom of the support portion.
Advantageously, the light module has a light source arranged opposite to a first end of the light guide and adapted to emit light, the light guide being configured to receive light via its first end and to guide light from the first end to the second end. The light guide is thus fastened at its second end and thus at the end opposite to the first end, via which end light from the light source is introduced into the light guide. Thus, the fastening of the light guide does not interfere with the optical function of the light guide.
The light module has a light source disposed towards the first end of each light guide, if desired.
Advantageously, the holding portion has a wing extending longitudinally from a front edge at the second end of the light guide towards the first end of the light guide to a rear edge formed by the second inclined surface, the rear edge being at the distal end of the positioning means and vertically between the light guide and the bottom of the support portion.
Thus, the wing is positioned against the lateral surface of the support portion between the second edge of the support element and the distal end of the positioning device. This makes it possible to ensure that the holding portion is properly attached to the supporting portion.
Advantageously, the lateral surface of the support element is inclined, and the wing follows the inclination, i.e. the inclination, of the lateral surface of the support element. For example, the lateral surface flares outwardly from its upper surface to the bottom of the support portion.
Advantageously, the holding portion is integral with the light guide. The light guide and the holding portion may for example be injection molded together as one piece. This ensures the positioning accuracy of the holding portion with respect to the light guide. Furthermore, the integral nature of the light guide and the retaining portion simplifies assembly.
Optionally, the holding portion is attached to the light guide. It may be attached by clamp fastening.
Advantageously, the first inclined surface and the second inclined surface are at an angle of between 10 ° and 30 ° with respect to a normal to the direction of extension through the distal end. This tilting allows easy assembly and provides sufficient tension to the light guide. Too little tilt, i.e. too little tilt, stretches the light guide, while too much tilt, i.e. too much tilt, does not stretch the light guide enough.
Advantageously, the support element has an additional lateral surface opposite to the lateral surface, and the support portion comprises a length L 0 ' additional positioning means protruding from the additional lateral surface in a direction transverse to the extension direction.
The positioning means and the additional positioning means are thus arranged on both sides of the positioning element.
Advantageously, the upper ends of the positioning means and the additional positioning means form together with the upper surface of the support element a channel in which the light guide is located. This channel allows easy positioning of the light guide.
Advantageously, the holding portion comprises two second inclined surfaces provided on both sides of the light guide, one of which cooperates with the first inclined surface of the positioning means and the other of which cooperates with the first inclined surface of the additional positioning means during assembly of the light guide with the holding portion on the supporting portion.
In particular, the holding portion may have additional wings. Thus, the wings and additional wings are provided on both sides of the light guide. The wings and the additional wings make it possible to ensure the positioning of the holder and the light guide on the support portion.
Advantageously, the first inclined surface comprises a width measured in a direction transverse to the direction of extension, said width being equal to the width of the second inclined surface.
Another aspect of the invention relates to a method for assembling an optical module having any of the foregoing features, characterized in that the method comprises a step of positioning the second inclined surface on an upper portion of the first inclined surface, and a step of sliding the second inclined surface until the second inclined surface reaches a surface of the supporting portion, whereby the light guide is tensioned.
The sliding on the first inclined surface makes it possible to stretch the light guide and make it less sensitive to vibrations.
The invention and its various applications will be better understood by reading the following description with reference to the accompanying drawings.

Detailed Description
Unless otherwise indicated, identical elements appearing in different figures are provided with a reference numeral.
An assembly 1 comprising a light module 2 and a housing 4 is visible in fig. 1. The housing 4 is intended to be fastened to a motor vehicle.
The light module 2 comprises a light source (not visible), a light guide 20 and a support portion 3. In the illustrated example, the light module 2 has three light guides 20 and a light source associated with each light guide 20. It should be understood that the number of light guides is not limiting. The light module 2 may alternatively have one, two or more than three light guides.
Each light guide 20 extends longitudinally in an extension direction E between a first end 200 and a second end 201 opposite the first end 200. The first end 200 of each light guide 20 is disposed to face a light source associated with the light guide 20 and is configured to receive light emitted by the light source. Thus, the first end 200 of the light guide 20 forms the input face of the light guide 20. The light guide 20 then directs the received light from its first end 200 to its second end 201. The light rays are transmitted through the light guide 20 to the outside of the light module 2 in a direction transverse to the propagation direction of the light rays in the light guide, i.e. in a direction transverse to the extension direction E. This direction is indicated by arrow R in fig. 1.
As can be seen in fig. 2, the first ends 200 of the light guides 20 are connected together by the connection portions 22 of the light modules 2. The connecting portion 22 is integral with the light guide 20. According to an alternative, the connection portion 22 may be attached to the light guide 20, in particular by clamp fastening.
The second ends 201 of the light guides 20 are connected together by the holding portions 22. The holding portion 21 is formed integrally with the light guide 20. According to an alternative, the holding portion 21 may be attached to the light guide 20, in particular by clamp fastening.
The support portion 3 is illustrated in fig. 3. It has a support element 13 for each light guide 20. Each support element 13 extends longitudinally in an extension direction E between a first edge 30 at a first end 200 of the light guide 20 and a second edge 31 at a second end 201 of the light guide 20. Each support element 13 extends vertically between an upper surface 131 on which the light guide 20 associated with the support element 13 is located and a bottom 321 of the support portion 3. In particular, the upper face 131 may have a concave shape complementary to the shape of the light guide 20 located thereon. The support element 13 also has a lateral surface 132 and an additional lateral surface 132', which is opposite to the lateral surface 132 in a direction transverse to the extension direction E and transverse to the emission direction of the light rays from the light module 2. The lateral surface 132 and the additional lateral surface 132' spread outwards from the upper face 131 up to the bottom 321 of the support portion 3.
The support portion 3 also has positioning means 32 and additional positioning means 32' associated with each support element 13. It will be appreciated that the support portion 3 may have only one locating means 32 associated with one or with each support element 13.
Both the positioning means 32 and the additional positioning means 32' extend longitudinally in the direction of extension E from a proximal end 322 facing the first edge 30 to a distal end 323 located at a distance d from the second edge 31. For each support element 13, the positioning means 32 protrude from the lateral surface 132 of the support element 13 in a direction transverse to the direction of extension E, while the additional positioning means 32 'protrude from the additional lateral surface 132' of the support element in a direction transverse to the direction of extension E. It will be noted that the positioning means 32 and the additional positioning means 32' associated with the same support element 13 extend in the same direction but opposite to each other.
Both the positioning means 32 and the additional positioning means 32' extend vertically between the lower end 325 and the upper end 324 of the bottom 321 facing the support portion 3.
In the illustrated example, the positioning device 32 and the upper end 324 of the additional positioning device extend vertically beyond the light guide 20 and are inclined toward the light guide 20. Thus, for each support element 13, the upper ends 324 of the positioning means and the additional positioning means together with the upper surface 131 of the support element 13 form a channel 320, in which channel 320 the light guide 20 is located.
For each positioning means 32 and additional positioning means 32', the upper end 324 at the distal end 323 is closer to the first end 200 of the light guide 20 than the lower end 325 at the distal end 323 in the extension direction E, such that the distal end 323 forms the first inclined surface 310.
The first end 200 of the light guide 20 is attached to the support portion 3 at the first edge 30 of the support element 13 via the connection portion 22.
As is evident from fig. 6, the bottom 321 of the support part 3 has a recess 301. During assembly of the light guide 20 onto the support portion 3, the connection portion 22 will be fitted into the recess 301 together with the light guide 21. Specifically, the connection portion 22 is located below the bottom 321 of the support 3, and the first end of the light guide 20 is accommodated in the recess 301 of the support 3. Other means for securing the first end 200 of the light guide 20 to the first edge 30 are possible without departing from the scope of the invention.
The second end 201 of the light guide 20 is attached to the support portion 3 via the holding portion 21 at the second edge 31 of the support element 13.
In particular, as can be seen in fig. 2, for each light guide 20, the holding portion 21 has a wing 211 and an additional wing 211', said wing 211 and additional wing 211' each extending longitudinally from a front edge 221 at the second end 201 of the light guide 20 towards the first end 200 of the light guide 20 up to a rear edge 222 formed by the second inclined surface 210. When the light guide is arranged on the support part 3, the wings 211 and the second inclined surfaces 210 of the additional wings 211 'are located at the distal ends 323 of the positioning means 32 and the distal ends 323 of the additional positioning means 32', respectively. The wings 211 and the additional wings 211' extend vertically between the light guide 20 and the bottom 321 of the support portion 3.
The wings 211 and the additional wings 211 'follow the inclination of the lateral surface 132 and the additional lateral surface 132', respectively, of the support element 13. Thus, when the light guide 20 is assembled on the support portion 3, the contact between the wings 211, 211 'and the lateral surfaces 132, 132' ensures that the light guide 20 is properly held in place.
For each light guide 20, the two second inclined surfaces 210 of the holding portion 12 associated with the light guide 20 in question have the same inclination as the first inclined surface 310 of the support portion 3. In addition, the first inclined surface 310 includes a width measured in a direction transverse to the extending direction, which is equal to the width of the second inclined surface 210.
The first inclined surface 310 of each positioning means 32 and the additional positioning means 32', and the second inclined surface 210 associated with the first inclined surface 310 in question, are at an angle of between 10 ° and 30 ° with respect to a normal to the direction of extension of the distal end passing through the positioning means 32 or the distal end of the additional positioning means 32' with the first inclined surface 310 in question. The angle enables ensuring that the second inclined surface 210 slides properly on the first inclined surface 310.
The second inclined surfaces 210 of the holding portion 21 are provided on both sides of the light guide 20 for each light guide. One of the two second inclined surfaces 210 is associated with a first inclined surface of the positioning means 32 associated with the support element 13 supporting said light guide 20 and the other of the two second inclined surfaces 210 is associated with a first inclined surface of the additional positioning means 32' associated with the support element 13 supporting said light guide 20.
It will be appreciated that for each light guide 20, the holding portion 21 may comprise only one wing and only one second inclined surface which will then cooperate with the first inclined surface of the positioning means associated with the support element 13 supporting said light guide 20 in question.
Each light guide 20 comprises a length L measured in the direction of extension between the second inclined surface 210 and the first end 200 of the light guide 20. In addition, the positioning device 32 and the additional positioning device 32' have a length L in the direction of extension 0 And L 0 '. For each light guide 20, the length L measured between the second inclined surface 210 and the first end 200 is such that it is smaller than the positioning means 3 before assembling the light guide 20 and the holding portion 21 onto the support portion 3Length L of 2 0 And the length L of the additional positioning device 32 0 '. For example, before assembling the light guide 20 onto the support portion 3, l=l 0 -1 mm is possible.
Once the light guides 20 are in place on the support portion 3, the length L measured between the second inclined surface 210 and the first end 200 is equal to the length L of the positioning means 32 for each light guide 20 0 And the length L of the additional positioning device 0 ’。
Specifically, during assembly of the light guides 20 on the support portion 3, the second inclined surface 210 slides on the first inclined surface 310 so as to lengthen the light guides 20 until each light guide is located on the upper surface 131 of its associated support element 13.
The assembly of the light guide 20 will now be described. The connecting portion 22 fits into the recess 301 in the support portion 3 together with the first end of the light guide 20, and the light guide 20 is then pivoted into contact with the support 3, in particular with the upper surface 131 of the support element 13. The light guide 20 is then engaged with the positioning means 32 and the additional positioning means 32' in a channel 320 formed by the upper surface 131. The second inclined surface 210 of the holding portion 21 is in contact with the upper portion of the first inclined surface 310 of the supporting portion 3, and the light guide 20 is stretched via a sliding movement indicated by an arrow M in fig. 4, and then the holding portion 21 is pressed against the bottom 321 of the supporting portion 3. The fastening screw 5 then locks the holding portion 21 and the light guide 20 to the support portion 3.
The light guide 20 is thus kept under tension and there is no risk of displacement thereof during vehicle vibrations.
