It is also a partition member for partitioning the accommodation space SP for accommodating parts. As the parts accommodated in the accommodation space SP, for example, a reinforcement 104 provided on the vehicle interior side IN at a position facing the driver's seat and supporting the steering ST and the like operated by the driver on the body, formed in a hollow shape. Examples include structures such as air conditioning ducts, various wire harnesses, and electronic parts that allow air to flow through the interior. Hereinafter, the configuration of the display device 1 applied to the instrument panel unit 100 will be described in detail with reference to FIGS. 1 and 2. Note that FIG. 1 omits the illustration of the internal structure of the instrument panel 101.

Specifically, the display device 1 includes a projection surface 2, a projector 3, and a control device 4.

The projection surface 2 is a screen provided on the projection surface installation surface 101a of the instrument panel 101. The projection surface installation surface 101a is composed of the surface of the interior side IN of the instrument panel 101 provided on the vehicle V, and more specifically, the surface of the most interior side IN of the instrument panel 101. The projection surface installation surface 101a constitutes an interior surface of the instrument panel 101.

It is located on the rear side of the front-rear direction X. The projection surface 2 is formed as a horizontally long region extending along the vehicle width direction Y. Here, the visual position EP is typically assumed in advance to be located within the so-called eye range of the vehicle V to which the display device 1 and the instrument panel unit 100 are applied. Here, the eye range is a "driver's eye range of an automobile" and corresponds to an area in which a driver's viewpoint determined in advance according to the vehicle V is located. The eye range is typically a statistical representation of the distribution of the driver's eye positions in vehicle V, eg, a predetermined percentage (eg, 95%) with the driver sitting in the driver's seat. Corresponds to the area that includes the position of the driver's eyes. Here, the visual position EP is assumed based on the driver of the vehicle V, but is not limited to this, and may be assumed based on other occupants of the vehicle V.

The projection surface installation surface 101a including the projection surface 2 of the present embodiment is typically configured as a surface that does not transmit light. Then, the projection surface 2 constitutes, for example, a diffusion type or a reflection type screen on the projection surface installation surface 101a. When the projected light representing the image is incident on the projection surface 2 from the projector 3, the projected light is reflected toward the visual position EP so that the driver or the like can visually recognize the image represented by the projected light. In order to specularly reflect the projected light representing the image projected from the projector 3 on the projection surface installation surface 101a, the projection surface 2 is subjected to, for example, surface processing such as microfabrication, surface coating, or a resin sheet. ing. Further, the projection surface 2 may be provided with an optical system surface layer such as a so-called microlens array.

In the projector 3 of the present embodiment, the reflecting unit 32 includes an intermediate mirror 32a as a first mirror and a final mirror 32b as a second mirror. Then, the projector 3 constitutes a bending projection optical system by two reflection systems, an intermediate mirror 32a and a final mirror 32b, which constitute the reflection portion 32, and a lens system such as a projection lens which constitutes the main body portion 31. Achieves a shorter focus.

In the projector 3 of the present embodiment, each part such as a main body part 31 and a reflection part 32 is provided between the hood part 102 and the instrument panel 101. The hood portion 102 is an eaves member provided at intervals from the instrument panel 101 along the vehicle height direction Z. A part of the hood portion 102 projects along the vehicle front-rear direction X to the upper side of the projection surface 2 in the vehicle height direction Z. The hood portion 102 extends from the right end to the left end along the vehicle width direction Y in parallel with the instrument panel 101.

The main body 31 is a projector main body that emits projected light representing an image, and is a light source such as an LED element, a display panel such as a microdisplay that forms an original image of the projected image, and a projection lens (projection lens, imaging lens). It is configured to include a lens system such as. The main body 31 of the present embodiment is provided in the space between the hood 102 and the instrument panel 101 and on the upper surface of the instrument panel 101 in the vehicle height direction Z. The main body portion 31 is fixed to the upper surface of the instrument panel 101 in the vehicle height direction Z in a positional relationship in which the exit portion 31a that emits the projected light faces the optical path space portion 103 side along the vehicle front-rear direction X. The main body 31 is installed on the instrument panel 101 via, for example, a fastening member such as a bolt or an adhesive. Here, the optical path space portion 103 is a space portion formed between the hood portion 102 and the instrument panel 101 in the vehicle height direction Z, and more specifically, a space portion partitioned by the hood portion 102 and the instrument panel 101. Is. The optical path space portion 103 serves as a propagation path for the projected light projected from the exit portion 31a of the main body portion 31 toward the projection surface 2. That is, the optical path space portion 103 constitutes an optical path of the projected light from the emitting portion 31a of the main body portion 31 to the projection surface 2. The optical path space portion 103 is located on the rear side of the exit portion 31a of the main body portion 31 along the vehicle front-rear direction X and extends from the emission portion 31a to the projection surface 2. The main body 31 emits projected light representing an image toward the rear side of the vehicle front-rear direction X, typically the visual position EP side, via the optical path space portion 103.

The reflection unit 32 constitutes a reflection system that reflects the projected light representing the image emitted from the main body 31 toward the projection surface 2. Here, as described above, the intermediate mirror 32a and the final mirror. It is configured to include 32b. The intermediate mirror 32a is an intermediate bending mirror that totally reflects the projected light representing the image emitted from the emitting unit 31a of the main body 31 toward the final mirror 32b. The final mirror 32b is a final reflection mirror that totally reflects the projected light from the intermediate mirror 32a, that is, the projected light emitted from the main body 31 and totally reflected by the intermediate mirror 32a toward the projection surface 2. The final mirror 32b of the present embodiment is a magnifying mirror that magnifies and reflects the image represented by the projected light, and is also a free-form mirror that corrects and reflects the distortion of the image represented by the projected light. The final mirror 32b that functions as a magnifying mirror is formed as a concave or convex mirror. In the final mirror 32b that functions as a magnifying mirror, the image represented by the projected light after being reflected by the final mirror 32b is relatively larger than the image represented by the projected light before being reflected by the final mirror 32b. The image is enlarged and reflected as described above. Further, the final mirror 32b that functions as a free curved mirror is formed as a mirror having an asymmetric shape with respect to the optical axis, unlike a spherical surface and a paraboloid, and is also called an aspherical mirror. That is, the final mirror 32b is formed as a mirror that is concave or convex and has an asymmetrical shape with respect to the optical axis. The final mirror 32b, which functions as a free-curved mirror, is formed in a shape corresponding to the surface shape of the projection surface 2 and the geometrical positional relationship of the final mirror 32b with respect to the projection surface 2, and directs the projected light toward the projection surface 2. At the time of reflection, the distortion is optically corrected so that the image represented by the projected light reflected on the projection surface 2 has a desired shape. Here, the intermediate mirror 32a is provided in the space portion between the hood portion 102 and the instrument panel 101, that is, in the optical path space portion 103 and on the upper surface of the instrument panel 101 in the vehicle height direction Z.

The control device 4 controls each part of the projector 3 in an integrated manner to control the display image by the projector 3. The control device 4 includes an electronic circuit mainly composed of a well-known microcomputer including a CPU, a ROM, a RAM, and an interface. The control device 4 is electrically connected to the projector 3 via an interface. The control device 4 may be connected to the projector 3 via the wire harness or the like described above, or may be housed in the main body 31 of the projector 3 and integrally configured with the projector 3. Further, the control device 4 may also be used as an ECU (Electronic Control Unit) or the like that collectively controls the entire vehicle V, or may be configured separately from the ECU and mutually detect signals, drive signals, and control. It may be configured to exchange information such as a command. The control device 4 outputs a control signal to the projector 3 by executing a control program stored in a ROM, RAM, or the like, controls the operation of the projector 3, and an image projected on the projection surface 2 by the projector 3. Performs various processes to control. The control device 4 is electrically connected to, for example, an image pickup device 4A that images the outside of the vehicle V, that is, the outside of the vehicle interior, and controls the projector 3 based on the image captured by the image pickup device 4A to control the vehicle V. An image including blind spot information on the passenger seat side as viewed from the driver's seat side, here, on the left side in the vehicle width direction Y, is projected onto the projection surface 2. Further, the control device 4 controls the projector 3, and in addition to the blind spot information, the vehicle information includes, for example, the speed of the vehicle, the integrated mileage, the cooling water temperature, the output rotation speed of the power source for traveling, the remaining fuel amount, and the battery storage. An image including the amount, various warning lights (warning lamps, so-called telltales), shift position indicators, direction indicators, navigation information, and the like may be projected on the projection surface 2.

Then, the display device 1 of the present embodiment properly projects an image on the instrument panel 101 by forming the projection surface 2 on which the projection light from the projector 3 configured as described above is projected into a concave shape. I am trying to be able to do it. Specifically, the projection surface 2 of the present embodiment is curved in a concave shape on the side opposite to the visual position EP in the vehicle width direction view (see FIG. 1) viewed along the vehicle width direction Y, and the projector 3 It is formed in a concave shape that collects the projected light from the light toward the visual position EP. The curved concave shape of the projection surface 2 collects the projected light from the projector 3 toward the visual position EP, for example, according to the geometrical positional relationship between the final mirror 32b of the projector 3 and the visual position EP. Is determined to be. The projection surface 2 is typically curved as a curved surface such that each reflection angle of the projected light projected and incident from the projector 3 is an angle at which the reflected light of the projected light is focused toward the visual position EP. It is formed in a concave shape. The projection surface 2 is further curved in a concave shape on the side opposite to the visual position EP in the vehicle height direction viewed along the vehicle height direction Z, and the projected light from the projector 3 is projected from the projector 3 at the visual position EP. It may have a concave shape that collects light on the side.

In the display device 1 and the instrument panel unit 100 described above, projected light representing an image is projected from the projector 3 toward the projection surface 2 provided on the interior side IN surface of the instrument panel 101 of the vehicle V. In this case, the display device 1 can be configured such that an obstacle object such as a occupant of the vehicle V or luggage is unlikely to intervene on the optical path of the projected light from the projector 3 to the projection surface 2. Therefore, the projected light is projected on the projection surface. It can be configured to be hard to be blocked before reaching 2. Further, in this case, the display device 1 is a surface (a surface visible from the visual position EP) on the upper side of the instrument panel 101 in which the instrument panel 101 tends to be provided with an airbag or the like in the vehicle height direction Z and on the rear side in the vehicle front-rear direction X. ) Can be configured so that there are no components of the display device 1 other than the projection surface 2. Further, with this configuration, the display device 1 can also suppress the influence on the accommodation space SP side, which is the space inside the instrument panel 101. As a result, the display device 1 can improve the mountability on the vehicle V, and for example, various images can be projected on the projection surface 2 without hindering the operation of the airbag. Since the projection surface 2 of the display device 1 is curved in a concave shape on the side opposite to the presumed visual position EP in the vehicle width direction, the display device 1 is projected from the projector 3. Light can be focused on the visual position EP side. With this configuration, the display device 1 can appropriately project the projected light to the vicinity of the rear edge of the vehicle front-rear direction X on the projection surface installation surface 101a of the instrument panel 101 to be the projection surface 2, and the projected light is used. The projection surface 2 on which the image is projected can be secured relatively widely. Further, with this configuration, the display device 1 can relatively increase the component of the projected light reflected to the visual position EP side on the entire projection surface 2, so that the image visible from the visual position EP has uneven brightness. Can be suppressed. As a result, the display device 1 and the instrument panel unit 100 can properly project an image onto the instrument panel 101 of the vehicle V.

Further, in the display device 1 and the instrument panel unit 100 described above, both the projection surface 2 and the projector 3 that projects an image on the projection surface 2 are provided on the instrument panel 101. With this configuration, in the display device 1, for example, even if the vehicle V vibrates, both the projection surface 2 and the projector 3 vibrate together with the instrument panel 101, and the relative positional relationship between the projection surface 2 and the projector 3 fluctuates. It can be a difficult configuration. With this configuration, the display device 1 and the instrument panel unit 100 can be configured such that the image projected on the projection surface 2 is less likely to be blurred.

Further, in the display device 1 and the instrument panel unit 100 described above, since the projector 3 includes the reflection unit 32, the projection light representing the image is projected on the projection surface 2 while changing the optical path through the reflection unit 32. Can be projected towards. As a result, the display device 1 and the instrument panel unit 100 can appropriately project the projected light representing the image toward the projection surface 2.

More specifically, the display device 1 and the instrument panel unit 100 described above can reflect the projected light emitted from the main body 31 by the intermediate mirror 32a and the final mirror 32b and project it onto the projection surface 2. Then, since the display device 1 and the instrument panel unit 100 can adjust the optical path of the projected light from the projector 3 to the projection surface 2 by combining the intermediate mirror 32a and the final mirror 32b, the display device 1 and the instrument panel unit 100 emit light from the main body 31. The positional relationship between the optical axis direction (emission direction) of the projected light and the projection surface 2 can be arbitrarily adjusted.

Further, the display device 1 and the instrument panel unit 100 described above include a final mirror 32b in which the reflecting unit 32 functions as a magnifying mirror. With this configuration, the display device 1 and the instrument panel unit 100 can magnify the image represented by the projected light emitted from the main body 31 to a desired size and project it on the projection surface 2. The image can be properly projected onto the instrument panel 101.

Further, the display device 1 and the instrument panel unit 100 described above include a final mirror 32b in which the reflecting unit 32 functions as a free-form curved mirror. With this configuration, the display device 1 and the instrument panel unit 100 can correct the distortion of the image represented by the projected light emitted from the main body 31 and project it on the projection surface 2, and in this respect as well, the instrument panel 101 of the vehicle V can be projected. The image can be projected properly.

Here, in the display device 1 and the instrument panel unit 100 described above, each part of the projector 3 is provided between the instrument panel 101 and the hood part 102, and the space between the instrument panel 101 and the hood part 102 is the space part of the projector 3. It functions as an optical path space portion 103 from to the projection surface 2. With this configuration, the display device 1 and the instrument panel unit 100 can appropriately secure the optical path from the projector 3 to the projection surface 2 by the optical path space portion 103, and in this respect as well, an image can be appropriately transmitted to the instrument panel 101 of the vehicle V.
