Embodiment Construction

[0024] figure 1 A head-up display 10 of a motor vehicle 12 , for example a motor vehicle 12 , for example a sedan, is shown, which has a housing 11 and a projection device 28 . The housing 11 of the head-up display 10 can, for example, comprise a housing upper part 14 , a housing lower part 16 and, for example, have a heat sink 18 . Inner space 20 of housing 11 of head-up display 10 is delimited here at least partially by inner walls 22 . A projection device 28 , such as a projector, may be arranged in the interior space 20 .

[0025] The inner wall 22 includes at least one reflective turning area 24, for example at figure 1 There are two reflective deflection areas 24 which are located, for example, on opposite areas of the inner wall 22 . The at least one deflection area 24 has a mirror-reflecting substance, ie a reflective material, which is preferably designed as a layer ( 27 ) of the inner wall 22 . Silver, aluminum or gold as preferred mirror-reflecting substances en...

Abstract

The invention relates to a housing (11) for a head-up display (10) of a motor vehicle (12), the housing having an inner wall (22) at least partially delimiting an interior of a projection device (28) for imaging (20) The projection device is used to project a virtual image in the beam path onto a reflective surface (30) in the interior of the motor vehicle (12). The housing (11) is characterized in that the inner wall (22) is provided with at least one reflective deflection area (24) for deflecting the beam path of a projection device (28) for imaging. The deflection region ( 24 ) can have a mirrored or mirror-reflecting layer ( 27 ) by applying a mirror on the surface ( 23 ) of the base body ( 25 ) of the inner wall ( 22 ) facing the interior space ( 20 ). Reflective, shapeless matter or material formation. The invention also relates to a corresponding head-up display (10), a correspondingly arranged motor vehicle (12), and a method for providing a housing (11) according to the invention.

Description

technical field [0001] The invention relates to a housing for a head-up display of a motor vehicle, the housing having an inner wall which at least partially delimits an interior space for an imaging projection device for projecting a virtual image in an optical path to reflective surfaces in the interior of the motor vehicle. Background technique [0002] In modern motor vehicles, a head-up display is usually installed, that is, a display device with a projection device for imaging. The projection device is used to project a virtual image in the optical path, that is, image information, onto a reflective surface on the windshield. [0003] In this case, the head-up display is usually positioned in the cockpit in front of the driver in the construction space. The heads-up display includes multiple mechanisms, optical individual components and electronic individual components. In order to deflect the virtual image emitted by the imaging projection device from the interior ...
