Definitions
- the present invention relates to a display device, in particular for a motor vehicle.
- Head-up display devices are known, in particular with the projection of an image towards a windshield as described in US Pat. No. 5,214,413 or to a reflection element.
- the high-vision vision display devices project information into the field of view of the space in front of the motor vehicle so that the driver of the motor vehicle can read this information without taking his eyes off the space in front of the motor vehicle . At the same time, the information can be read without modification of the accommodation of the eyes of the driver of the vehicle.
- the display devices can take into account several positions of the head (or eyes) of the user of the vehicle.
- a disadvantage of such devices according to the prior art consists in the fact that the efforts to achieve the connection between the support element of a reflection element and / or display and the reflection element and / or display are relatively high, especially because the constraints must be low (not to deform the reflection element and / or display) while ensuring good maintenance.
- the present invention is intended in particular to overcome the drawbacks of the prior art, especially those mentioned above, and also aims to provide a head-up display device having a reflection element and / or display that is connected to its support reliably and with reduced costs.
- a display device in particular for a motor vehicle, comprising a projection module for generating an image for projection in the normal direction of view of a user of the device. display according to an optical path,
- the display device comprising a reflection and / or display element, as well as a support element for the reflection and / or display element,
- the display device further comprising a holding member
- the reflection and / or display element is held securely between the support member and the holding member and in a fixed position with respect to the support member.
- a thermal decoupling to be carried out to protect, on the one hand, the components (in particular the electronic components) which are placed behind the reflection element and / or display with respect to the thermal flux due to the light incident on the reflection and / or display element, and, secondly, to protect the reflection and / or display element (particularly with respect to deformations due to too much heating) of the heat flow from the components behind the reflection element and / or display.
- a preferred refinement of the invention resides in the fact that the reflection and / or display element and the support element are connected via a first, second, third, fourth, fifth and sixth surfaces.
- first, second, and third surfaces being curved surfaces having a first radius
- fourth, fifth, and sixth surfaces being planar or curved surfaces having a second radius, the second radius being at least twice the first radius
- each of the first, second and third surfaces corresponds to a surface of the fourth, fifth and sixth surfaces
- the first surface corresponds to the fourth surface and vice versa
- the second surface corresponds to the fifth surface and vice versa
- the third surface corresponds to the sixth surface and vice versa
- the seventh, eighth, and ninth surfaces being curved surfaces having a third radius
- the tenth, eleventh and twelfth surfaces being planar or curved surfaces having a fourth radius, the fourth radius corresponding to at least twice the third radius.
- each of the seventh, eighth and ninth surfaces corresponds to a surface of the tenth, eleventh and twelfth surfaces (in particular the seventh surface corresponds to the tenth surface and vice versa, the eighth surface corresponds to the eleventh surface and vice versa , and the ninth surface corresponds to the twelfth surface and vice versa). It is thus possible to make a connection between the reflection element and / or display and the holding element in a simple and inexpensive way.
- the holding member is attached to the support member such that surfaces of the support member and the holding member rest on corresponding surfaces. of the reflection and / or display element, respectively.
- a preferred refinement of the invention lies in the fact that the reflection element and / or display comprises a main extension plane and two opposite sides and that the reflection element and / or display comprises at least one pair of surfaces on each side at corresponding locations.
- a preferred refinement of the invention lies in the fact that the first, second and third surfaces, as well as the tenth, eleventh and twelfth surfaces are surfaces of the reflection and / or display element, which the fourth, fifth and sixth surfaces are surfaces of the support member, and the seventh, eighth and ninth surfaces are surfaces of the holding member.
- Yet another preferred development of the invention lies in the fact that the reflection element and / or display being able to be moved between a rest position and at least one display position such as the reflection element and / or display is moved between its rest position and its at least one display position by
- FIG. schematic section of a display device according to the present invention Figure 2 is a schematic sectional view of a portion of the display device according to the present invention with the reflection element and / or display
- FIGS. 3 to 9 are perspective schematic views or else detailed views of the reflection and / or display element or the link of the reflection and / or display element with the support and / or the holding member.
- a display device 10 comprises a projection module 11 which generates an image in the normal viewing direction of a user of the display device 10 along a path optical 12.
- the optical path 12 normally comprises at least one reflection and / or display element 13.
- the optical path 12 may comprise a reflection element outside the projection module 11 (as shown in FIG. 1).
- a reflection and / or display element 13 is typically integrated in the projection module 11.
- the optical path 2 may also comprise two reflection elements or two reflection and / or display elements, in particular all integrated into the projection module.
- the normal direction of view 15 is the direction of view of a user of the display device 10, in particular a vehicle driver, when he looks, in particular through a windshield 14, the outside which is in front of the vehicle. vehicle.
- the reflection and / or display element 13 can be positioned in a rest position and in at least one display position.
- the reflection element and / or display 13 is for example positioned inside a housing of the display device 10, in particular inside the projection module 11.
- the change of position of the rest position and the display position of the reflection element and / or display 13 is made through a rotary movement and / or translation.
- the reflection and / or display element 13 must be positioned relative to a housing, in particular the projection module 11, which is called a support element 16.
- a support element 16 or a support 16 is associated with the reflection element and / or display 13.
- the support 16 or the support member 16 may be capable of being driven between different positioning states, in particular via the motor element.
- FIG. 2 a schematic perspective view of a part of the display device (in particular the projection module 11) according to the present invention is shown with the reflection and / or display element 13 and the element In addition, a holding member 16 'is shown in FIG. 2. The reflection and / or display element 13 is positioned between the support member 16 and the holding member 16'.
- Figures 3 to 9 show schematic perspective views and / or detail views of the reflection and / or display element or the link of the reflection and / or display element with the support and / or the holding member.
- the reflection element and / or display 13 is pressed against the support member 16, and the reflection element and / or display 16 is bonded (or supported) against the support member 16 in three different locations using first, second, third, fourth, fifth and sixth surfaces.
- the first, second and third surfaces 17 are curved surfaces having a first radius
- the fourth, fifth and sixth surfaces 18 are planar or curved surfaces having a second radius, the second radius corresponding to at least twice the first radius.
- the first, second and third surfaces 17 are formed on the reflection element and / or display 13 and more precisely on its side which is oriented towards the support element 16.
- the fourth, fifth and sixth surfaces 18 are formed on the support member 16 so that the fourth, fifth and sixth surfaces 18 are located opposite the first, second and third surfaces 17 (see Figures 3, 4, 5 and 6).
- the seventh, eighth and ninth surfaces 19 are curved surfaces having a third radius, while the tenth, eleventh and twelfth surfaces 20 are planar or curved surfaces having a fourth radius, the fourth radius corresponding to at least twice the third radius.
- the seventh, eighth and ninth surfaces 19 are formed on the holding element 16 'and more precisely on its side which is oriented towards the reflection and / or display element 13.
- the tenth, eleventh and twelfth surfaces 20 are formed on the reflection and / or display element 13 so that the tenth, eleventh and twelfth surfaces 20 are located opposite the seventh, eighth and ninth surfaces 19 (see Figures 7, 8 and 9).
