  The instrument panel unit 100 includes an instrument panel (hereinafter may be abbreviated as “instrument panel”) 101 and a display device 1 that projects and displays various images on a projection surface 2 provided on the instrument panel 101. This is a unit with a display device that realizes proper image projection onto the instrument panel 101. The instrument panel 101 is a member that extends along the vehicle width direction Y intersecting the vehicle longitudinal direction X on the vehicle interior side IN where the driver's seat or the like is provided in the vehicle V and on the front side in the vehicle longitudinal direction X. is there. The instrument panel 101 extends from the right end to the left end along the vehicle width direction Y in the vicinity of a so-called windshield (so-called windshield) WS on the vehicle interior side IN. The instrument panel 101 is an interior member that is provided in the space portion on the vehicle interior side IN so as to be exposed in the vehicle interior side IN, and has various types between the front wall surface in the vehicle longitudinal direction X of the body of the vehicle V. It is also a partition member that partitions the storage space SP that stores the components. As the parts accommodated in the accommodation space SP, for example, a reinforcement 104 that is provided at a position facing the driver's seat on the vehicle interior side IN and supports the steering ST or the like operated by the driver on the body, is formed in a hollow shape. Examples of the structure include air conditioning ducts, various wire harnesses, and electronic components through which air can flow. 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. In FIG. 1, the internal structure of the instrument panel 101 is not shown.

  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 101 a of the instrument panel 101. The projection plane installation surface 101 a is configured by a surface on the vehicle interior side IN of the instrument panel 101 provided on the vehicle V, more specifically, a surface of the instrument panel 101 closest to the vehicle interior side IN. The projection plane installation surface 101 a constitutes an interior surface in the instrument panel 101. The projection plane 2 is an area where projection light representing an image is projected from the projector 3 on the projection plane installation plane 101a, and is set at an arbitrary position. Here, the projection surface 2 is provided on the side opposite to the driver seat side of the vehicle V with respect to the center C of the instrument panel 101 in the vehicle width direction Y, in other words, on the side opposite to the side where the steering ST is provided. The projection surface 2 of the present embodiment is provided on the left side of the instrument panel 101 in the vehicle width direction Y. Furthermore, the projection plane 2 of the present embodiment is a position that can be viewed from a previously assumed visual position EP in the instrument panel 101, typically the vehicle height direction Z (vertical direction) upper side, and the vehicle It is located on the rear side in 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 as being typically located within a so-called eye range in the vehicle V to which the display device 1 and the instrument panel unit 100 are applied. Here, the eye range is an “automobile driver eye range” and corresponds to a region where the viewpoint of the driver 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 eyes in the vehicle V. For example, the eye range is a predetermined ratio (for example, 95%) with the driver sitting in the driver's seat. This corresponds to a region including the driver's eye position. Here, the visual position EP is assumed based on the driver of the vehicle V. However, the visual position EP is not limited to this and may be assumed based on another passenger of the vehicle V.

  The projection plane installation surface 101a including the projection plane 2 of the present embodiment is typically configured as a plane that does not transmit light. The projection surface 2 constitutes, for example, a diffusive or reflective screen on the projection surface installation surface 101a. When projection light representing an image from the projector 3 is incident on the projection surface 2, the projection surface 2 reflects the projection light toward the viewing position EP so that the driver or the like visually recognizes the image represented by the projection light. The projection surface 2 is subjected to, for example, surface processing such as fine processing, surface coating, or a resin sheet in order to properly reflect the projection light representing the image projected from the projector 3 on the projection surface installation surface 101a. ing. The projection surface 2 may be provided with an optical system surface layer such as a so-called microlens array.

The projector 3 includes a main body unit 31 and a reflection unit 32. The projector 3 may be unitized by the main body 31 and the reflection unit 32 being housed and assembled in a casing. Typically, the projector 3 is preferably a so-called short focus projector so that the projector 3 is arranged as close as possible to the projection plane installation surface 101a on which the projection plane 2 is provided, and the close projection onto the projection plane 2 is realized. . In the projector 3 of the present embodiment, the reflection unit 32 includes an intermediate mirror 32a as a first mirror and a final mirror 32b as a second mirror. Then, the projector 3 forms a bending projection optical system by using the two reflection systems of the intermediate mirror 32 a and the final mirror 32 b that constitute the reflection unit 32 and a lens system such as a projection lens that constitutes the main body unit 31. Short focus has been realized.

  In the projector 3 of the present embodiment, each part such as the main body part 31 and the reflection part 32 is provided between the hood part 102 and the instrument panel 101. The hood portion 102 is a gutter member provided at a distance from the instrument panel 101 along the vehicle height direction Z. A part of the hood portion 102 extends to the upper side in the vehicle height direction Z of the projection plane 2 along the vehicle longitudinal direction X. The hood part 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 projection light representing an image, a light source such as an LED element, a display panel such as a micro display that forms an original image of the image to be projected, a projection lens (projection lens, imaging lens). Etc., including a lens system. The main body 31 of the present embodiment is provided in a 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 31 is fixed to the upper surface of the instrument panel 101 in the vehicle height direction Z in such a positional relationship that the emitting portion 31a that emits projection light faces the optical path space portion 103 along the vehicle longitudinal direction X. The main body 31 is installed on the instrument panel 101 via a fastening member such as a bolt or an adhesive, for example. Here, the optical path space portion 103 is a space portion formed between the hood portion 102 and the instrument panel 101 with respect to the vehicle height direction Z, more specifically, a space portion defined by the hood portion 102 and the instrument panel 101. It is. The optical path space portion 103 serves as a propagation path of projection light projected from the emitting portion 31 a of the main body portion 31 toward the projection plane 2. That is, the optical path space portion 103 constitutes the optical path of the projection light from the emission portion 31 a of the main body portion 31 to the projection plane 2. The optical path space portion 103 is located on the rear side of the emission portion 31a of the main body portion 31 along the vehicle longitudinal direction X and extends from the emission portion 31a to the projection plane 2. In the main body 31, the emitting unit 31 a emits projection light representing an image toward the rear side in the vehicle front-rear direction X, typically the viewing position EP side, through the optical path space unit 103.

  The reflection unit 32 constitutes a reflection system that reflects the projection light representing the image emitted from the main body unit 31 toward the projection plane 2, and here, as described above, the intermediate mirror 32a and the final mirror 32b is comprised. The intermediate mirror 32a is an intermediate bending mirror that totally reflects the projection light representing the image emitted from the emission part 31a of the main body part 31 toward the final mirror 32b. The final mirror 32b is a final reflection mirror that totally reflects the projection light from the intermediate mirror 32a, that is, the projection light representing the image emitted from the main body 31 and totally reflected by the intermediate mirror 32a toward the projection plane 2. The final mirror 32b of the present embodiment is a magnifying mirror that magnifies and reflects an image represented by the projection light, and is also a free-form surface mirror that reflects and corrects distortion of the image represented by the projection light. The final mirror 32b functioning as a magnifying mirror is formed as a concave or convex mirror. In the final mirror 32b functioning as a magnifying mirror, the image represented by the projection light after being reflected by the final mirror 32b is relatively larger than the image represented by the projection light before being reflected by the final mirror 32b. In this way, the image is magnified and reflected. The final mirror 32b functioning as a free-form surface mirror is formed as a mirror having an asymmetric shape with respect to the optical axis, and is also called an aspherical mirror. That is, the final mirror 32b is formed as a concave or convex mirror that is asymmetric with respect to the optical axis. The final mirror 32 b that functions as a free-form surface mirror is formed in a shape corresponding to the surface shape of the projection surface 2 and the geometric positional relationship of the final mirror 32 b with respect to the projection surface 2, and directs the projection light toward the projection surface 2. When reflecting, the distortion is optically corrected so that the image represented by the projection light reflected on the projection surface 2 has a desired shape. Here, the intermediate mirror 32 a is provided in the space between the hood 102 and the instrument panel 101, that is, in the optical path space 103 and on the upper surface of the instrument panel 101 in the vehicle height direction Z.

The final mirror 32b is installed on the hood part 102 via a fastening member such as a bolt or an adhesive, for example.

  The control device 4 controls each part of the projector 3 and controls a display image by the projector 3. The control device 4 includes an electronic circuit mainly composed of a 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 above-described wire harness or the like, or may be housed in the main body 31 of the projector 3 and configured integrally with the projector 3. The control device 4 may also be used as an ECU (Electronic Control Unit) that controls the entire vehicle V in an integrated manner, or is configured separately from the ECU, and detects, drives, and controls each other. It may be configured to exchange information such as commands. The control device 4 outputs a control signal to the projector 3 by executing a control program stored in a ROM, a RAM, or the like, controls the operation of the projector 3, and the image projected on the projection plane 2 by the projector 3 Various processes for controlling are performed. For example, the control device 4 is electrically connected to an imaging device 4A that images the outside of the vehicle V, that is, the outside of the passenger compartment, and controls the projector 3 based on the image captured by the imaging device 4A. An image including blind spot information on the passenger seat side viewed from the driver seat side, here, the left side in the vehicle width direction Y is projected on the projection plane 2. In addition to the blind spot information, the control device 4 controls the projector 3 as vehicle information such as vehicle speed, integrated travel distance, cooling water temperature, output rotational speed of the driving power source, fuel remaining amount, battery power storage, and the like. An image including a quantity, various warning lights (warning lamp, so-called tell tale), a shift position indicator, a direction indication symbol, navigation information, and the like may be projected on the projection plane 2.

  The display device 1 of the present embodiment appropriately projects an image on the instrument panel 101 by forming the projection surface 2 onto which the projection light from the projector 3 configured as described above is projected in a concave shape. To be able to. Specifically, the projection surface 2 of the present embodiment is curved in a concave shape on the side opposite to the viewing position EP when viewed in the vehicle width direction (see FIG. 1) viewed along the vehicle width direction Y. Is formed in a concave shape that condenses the projection light from the viewing position EP side. The curved concave shape of the projection surface 2 condenses the projection light from the projector 3 toward the visual position EP according to, for example, the geometrical positional relationship between the final mirror 32b of the projector 3 and the visual position EP. It is determined as follows. The projection surface 2 is typically curved as a curved surface such that each reflection angle of the projection light projected and incident from the projector 3 is an angle at which the reflected light of the projection light is collected toward the viewing position EP. The concave shape is formed. The projection surface 2 is further curved in a concave shape on the side opposite to the viewing position EP when viewed in the vehicle height direction Z along the vehicle height direction Z, and the projection light from the projector 3 is viewed at the viewing position EP. A concave shape for condensing on the side may be provided.

  In the display device 1 and the instrument panel unit 100 described above, projection light representing an image is projected from the projector 3 toward the projection surface 2 provided on the surface of the instrument panel 101 on the vehicle panel IN. In this case, the display device 1 can be configured such that an obstacle such as an occupant or a luggage of the vehicle V is unlikely to intervene on the optical path of the projection light from the projector 3 to the projection surface 2. It can be set as the structure which is hard to be interrupted before reaching 2. Further, in this case, the display device 1 is a surface on the upper side in the vehicle height direction Z of the instrument panel 101 that tends to be provided with an air bag or the like and on the rear side in the vehicle front-rear direction X (a surface that can be viewed from the visual position EP). ) Can be configured such 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 that is the space inside the instrument panel 101. As a result, the display device 1 can improve the mountability on the vehicle V, and can project various images on the projection plane 2 without hindering the operation of the airbag, for example. In the display device 1, the projection surface 2 is formed in a concave shape that is curved in a concave shape on the side opposite to the assumed visual position EP in the vehicle width direction. Light can be collected on the viewing position EP side. With this configuration, the display device 1 can appropriately project the projection light near the rear edge in the vehicle front-rear direction X on the projection surface installation surface 101a of the instrument panel 101 to obtain the projection surface 2, which is based on the projection light. The projection plane 2 on which the image is projected can be secured relatively wide. Further, with this configuration, the display device 1 can relatively increase the component of the projection light that is reflected toward the viewing position EP on the entire projection surface 2, so that uneven brightness occurs in an image that can be viewed from the viewing position EP. Can be suppressed. As a result, the display device 1 and the instrument panel unit 100 can appropriately project an image onto the instrument panel 101 of the vehicle V.

A difficult configuration can be obtained. With this configuration, the display device 1 and the instrument panel unit 100 can be configured such that the image projected on the projection plane 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 reflecting unit 32, the projection light representing the image while changing the optical path through the reflecting unit 32 is projected onto the projection surface 2. Can be projected toward. As a result, the display device 1 and the instrument panel unit 100 can appropriately project the projection light representing the image toward the projection plane 2.

  More specifically, the display device 1 and the instrument panel unit 100 described above can reflect the projection 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. The display device 1 and the instrument panel unit 100 can adjust the optical path of the projection light from the projector 3 to the projection surface 2 by combining the intermediate mirror 32a and the final mirror 32b. The positional relationship between the optical axis direction (exiting direction) of the projected light and the projection plane 2 can be arbitrarily adjusted.

  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 enlarge the image represented by the projection light emitted from the main body 31 to a desired size and project it on the projection plane 2. An image can be appropriately projected onto the instrument panel 101.
