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 known art consists in the fact that the efforts to achieve specific functionalities, such as thermal protection and / or protection against parasitic reflections, as well as the link between the support element of a reflection and / or display element and the reflection and / or display element are relatively high.
- 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 which is connected to its support reliably and with reduced costs, while including additional functionalities in terms of thermal protection and / or against parasitic reflections.
- a display device particularly 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 vehicle.
- display device 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 such that the reflecting and / or display element is held securely between the support member and the holding member and in a position fixed relative to the support member, the holding member further comprising a protruding portion with respect to the reflection element and / or display.
- 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. Furthermore, it is provided according to the present invention that the protruding portion relative to the reflection element and / or display reduces spurious reflections of the reflection element and / or display.
- the holding element according to the present invention is therefore advantageously capable of performing the functions of mechanical support, thermal protection as well as protection against parasitic reflections.
- 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
- reflection and / or display element and the holding element are connected via a seventh, eighth, ninth, tenth, eleventh and twelfth surfaces,
- 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 third 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.
- the protruding portion with respect to the reflection and / or display element comprises a curvature.
- 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.
- 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

- 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 the latter looks, in particular through a windshield 14, the outside which is in front the 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 member 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 states of positioning, in particular via the motor element.
