Definitions
- Body panel capable of displaying an image
- the invention relates to vehicles, more specifically to motor vehicles, and more particularly to vehicle body panels.
- Body panel means one of the elements forming the outer skin of a vehicle.
- the body panels that can display images are provided with optical panels capable of diffusing an image. They may be LED-type panels (for light-emitting diode) or OLED (for organic light-emitting diode, organic light-emitting diode in French). These panels have a certain flexibility allowing them to be affixed to body panels which are generally more or less curved. The optical panels affixed to the body panels generate and then broadcast visible images from outside the vehicle.
- the flexibility of the optical panels is limited. Therefore, it is not possible to affix an optical panel on a vehicle whose design would have excessive curvatures. In addition, the deformation of the optical panels can lead to a distortion of the images displayed by the latter.
- An object of the invention is therefore to provide a body panel capable of displaying information, the body panel can be produced at lower costs than those of the prior art and having a satisfactory robustness with respect to the exposure of vehicles. body panels.
- the invention has for this purpose a motor vehicle body panel comprising an outer face visible from outside the motor vehicle and an inner face, the body panel being adapted to display on its outer face an image projected on its inner face.
- the body panel according to the invention is comparable to a screen on which an image is projected at a distance, generally on its internal face, like a rear projection cinema screen, for example.
- the body panel does not have to be equipped with one or more LED or OLED panels, which significantly reduces the cost of production of the body panels.
- the body panel has only a screen role, it is possible to pre-deform the image generated by an image transmission device so that the image is displayed in a manner optimal on the body panel with a particular design (presence of curvatures, edges, etc.).
- the body panel according to the invention may further comprise one or more of the following features:
- the body panel is transparent or semi-opaque
- the body panel is made of a material selected from polyamides, polycarbonates or polymethyl methacrylate;
- the body panel includes pigments
- the quantity of pigments is between 0.1 and 10 percent by weight relative to the total weight of the body panel
- the pigments comprise mica
- the body panel further comprises an image display film
- the image display film is glued to a main body of the body panel
- the image display film is overmolded in the main body of the body panel.
- the invention also relates to an assembly of a body panel according to the invention and an image diffusion device.
- the image diffusion device is a source of laser light
- the invention also relates to the use of a body panel according to the invention in order to perform a diagnosis of the body panel, to display a light signal corresponding to the signaling lighting and / or to display the availability of places in a vehicle
- FIG. 1 is a schematic perspective view of a motor vehicle comprising a bodywork panel according to the invention
- FIG. 2 is an exploded view of an assembly consisting of a body panel according to the invention and an image diffusion device,
- FIGS. 3A and 3B are sectional views of a bodywork panel according to the invention.
- FIG. 4 is a sectional view of a bodywork panel according to a first embodiment of the invention.
- FIG. 5 is a sectional view of a body panel according to a second embodiment of the invention.
- FIG. 1 represents a motor vehicle 2 comprising a bumper 4 made up in part of a panel 6 able to display on its external face 8 an image projected on its inner face 10.
- the term "external face” means the face of the visible panel 6. from the outside of the vehicle, the inner face being the face of the panel 6 opposite to the outer face.
- the image display can have many purposes: it can for example be to make a diagnosis of the panel 6 by the user facing the latter, to display an image on the vehicle in rotation (for example young driver, etc.), to display a signal related to the signaling light (sidelights, flashing lights, hazard warning lights) or to display a decorative image on the sign 6. Colors displayed images such as the luminous intensity of the latter may vary according to the nature of the images to be displayed.
- the panel 6 retains its robustness, unlike the prior art in which LED panels are mounted on body panels.
- the panel is less sensitive to impacts because the source of emission of the image is behind and at a distance from the latter, the distance between the source of emission of the image and the body panel being able to be determined according to the deforming the body panel in order to place the image emission source far enough away so as not to be damaged by deformation of the body panel (to a certain degree of deformation of the latter), a direct diffusion of an image on a bodywork panel makes it possible to produce body panels that can have great freedom of shape, contrary to the prior art in which a panel can not include curves that are too large because of the low flexibility of LED panels,
- the image to be displayed can be pre-distorted before displaying on the panel in order to be displayed correctly on the latter (for example by adjusting the focal length according to the shape of the bodywork panel, the projected image adapting to the shape for optimal display), and
- the image display is possible even in case of deformation of the body panel because the source is not necessarily damaged during an impact, unlike an LED panel.
- the image is projected by an image diffusion device 12 (shown in FIG. 2) located at a distance from the internal face 10 of the panel 6, for example being fastened to a structural part of the vehicle 2 (it can also be be attached to the panel 6 being at a distance from the latter).
- an image diffusion device 12 shown in FIG. 2 located at a distance from the internal face 10 of the panel 6, for example being fastened to a structural part of the vehicle 2 (it can also be be attached to the panel 6 being at a distance from the latter).
- the 10 may be greater than or equal to 60 mm. Preferably, it is between 60 and 150 mm.
- the distance of 60 mm makes it possible to place the image diffusion device 12 out of reach of the panel 6 in case of deformation of the latter due to a shock at low speed (for example if it is a light curtain -chocs).
- the image diffusion device 12 is fixed to the vehicle (to the panel 6 or to a structural part) so as to be able to follow the movement made by the panel 6 deforming while remaining at a distance from it. last (for example, maintaining the initial distance greater than or equal to 60 mm) and this in order to avoid damaging the image diffusion device 12 in the event of shocks at the body panel 6.
- the image-diffusion device 12 may for example be a laser projector or any other type of image-diffusion device capable of diffusing an image that can be displayed on the body panel 6. It may preferentially be a short-throw device for minimizing the distance between the diffusion device 12 and the inner face 10 of the panel 6 while having the possibility of displaying an image on the entire panel 6.
- the broadcasting device 12 is connected to an electronic control unit 14 able to control the image diffusion when this is requested by the user or necessary, depending on the nature of the image to be displayed. For example, displaying an image as part of performing a diagnosis can be controlled by the user.
- an electronic control unit 14 able to control the image diffusion when this is requested by the user or necessary, depending on the nature of the image to be displayed. For example, displaying an image as part of performing a diagnosis can be controlled by the user.
- the electronic control unit 14 It is possible to program the electronic control unit 14 so that the latter automatically displays a fault message on the panel 6 in the event of a collision having caused damage to the latter.
- the panel 6 In order to be able to display on its external face 8 an image projected on its internal face 10, the panel 6 is transparent or semi-opaque.
- Semi-opaque means the case in which the panel 6 is opaque when no image is projected on the latter but displays an image when the broadcasting device 12 operates.
- the panel 6 may for example be made of polymethyl methacrylate, polyamide, polycarbonate or any other material for making a panel 6 transparent or semi-opaque.
- FIGS. 3A and 3B The general principle of the invention is set forth in FIGS. 3A and 3B.
- the diffusion device 12 diffuses an image (represented by the beams 16, 18 and 20) which reaches the internal face 10 of the panel 6. The image is visible on the external face of the panel 6 which is transparent or semi-opaque.
- the beams 16, 18 and 20 directly reach the outer face 8 of the panel 6 to display the image projected by the image diffusion device 12.
- the panel 6, made of a transparent or semi-opaque material may for example be made of a plastics material comprising elements enabling image display.
- the panel may alternatively comprise elements in addition to the plastic material component elements added during or after the manufacture of the panel.
- Mica can be used alone or with other pigments (for example titanium dioxide). carbon black or iron oxide). It is also possible to use phosphorus pigments alternately or in addition to the mica.
- the quantity of pigments 22 present in the panel 6 is preferably between 0.1 and 10 percent by weight relative to the total weight of the panel 6.
- the pigments 22 have the capacity to absorb in a high manner the light emitted by the device of image diffusion 12 to allow the display of the image.
- a transmitting device being a source of laser light
- the panel 6 can also be painted with a paint allowing the projected images to be displayed on its outer surface 8.
- the paint layer can be made on the outer face 8 of the panel 6 (as may be the case in FIG. 3B) or be made on the inner face 10 of the latter (as may be the case in the figure 3A).
- the panel 6 comprises an image display film 24 able to allow the display of images on the external face 8.
- the image display film 24 may for example be a holographic film. In general, it is a film capable of displaying an image on its outer face 8, the image being projected on its other side.
- the film 24 may be, as shown in Figure 5, overmolded in the panel 6 which protects it from scratches, aging, etc.. It may alternatively be fixed, for example by gluing, to the main body 26 of the panel 6 after molding of the latter, on the internal face 10 of the panel 6 (protection against scratches and friction due for example to contact with an external element) or on the external face 8 of the panel 6. In both cases (overmolding or gluing), the image display film 24 may play a role in the appearance of the panel 6, conferring an opaque appearance when no image is displayed and displaying an image when the broadcasting device 12 is in operation.
- a panel according to the invention it is particularly possible to use a panel according to the invention to perform other functions than those mentioned above, such as the display of messages for other drivers.
- the display of images is made possible by elements other than those mentioned above, for example by the presence of a material diffusing on the internal face or on the external face of the body panel, a porous material for allow the display while letting the light through. It is also possible to play on the texture of the surface of the body panel to allow the diffusion of images, for example through the presence of a layer of material, the same material as the body panel, having special structural properties.
