  However, in a configuration in which the combiner is folded on the upper surface of the instrument panel portion or stored inside the instrument panel portion when not in use, it is necessary to make a hole for the combiner on the upper surface of the instrument panel portion. There are many disadvantages in terms of design and design of the instrument panel, such as the need for a space for installing the combiner inside.

  The present invention has been made in view of the above circumstances, and provides a combiner and a head-up display that can eliminate the space for installing the combiner inside the instrument panel unit and can suppress the deterioration of the design of the instrument panel unit due to the combiner installation. The task is to do.

  In order to solve the above-described problems, the present invention is a combiner (10) for a head-up display of a vehicle, and a non-use position that covers the surface of a front cover (9) of a meter (1) mounted on the vehicle. And a use position that rises above the front cover.

  According to the combiner of the present invention, it is provided so as to be movable between the non-use position covering the surface of the front cover of the meter and the use position raised above the front cover. Space can be eliminated. Moreover, since it is not necessary to make a hole in the upper surface of an instrument panel part, the deterioration of the design property of the instrument panel part accompanying a combiner installation can be suppressed.

  In the combiner according to the present invention, when the combiner is in the non-use position, the end (10a) of the combiner located on the upper end (9a) side of the front cover rotates about an axis line oriented in the left-right direction of the vehicle. Provided possible.

  Thus, by using the end portion of the combiner located on the upper end (9a) side of the front cover as the rotation shaft, the combiner can be raised above the front cover when the combiner is used.

The head-up display of the present invention is
A combiner of the present invention;
Control means (8, 13) for moving the combiner from the non-use position to the use position when the vehicle is powered on.

  According to this, the space for a combiner installation can be made unnecessary inside an instrument panel part, and the deterioration of the design property of an instrument panel part can be suppressed. In addition, the control means moves the combiner from the non-use position to the use position when the vehicle is turned on, so that the burden on the user can be reduced compared to manually moving the combiner. It is possible to avoid hiding the display.

  The control means moves the combiner from the use position to the non-use position when the vehicle is powered off. As a result, the operation burden on the user can be reduced as compared with the case where the combiner is moved manually. In addition, when not in use, the combiner is turned down at the non-use position, so that the appearance of the passenger compartment can be improved.

It is sectional drawing which looked at the vehicle interior part in which the combination meter and the head-up display were arrange | positioned from the side. It is the figure which showed the state of the combiner at the time of non-use. It is the figure which showed the state of the combiner at the time of use.

  Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a combination meter 1 is disposed in a space where a driver D of a vehicle is seated, that is, in front of a driver seat space. The combination meter 1 is disposed so as to be fitted into the opening 100a of the instrument panel unit 100 disposed in front of the driver seat space.

  The combination meter 1 has a plurality of meters for displaying vehicle information such as vehicle speed, engine speed, remaining fuel amount, engine coolant temperature, and the like. The combination meter 1 includes a case 2 and various components such as a dial plate 3, a pointer 4, and a circuit board 5 accommodated in the case 2. The dial plate 3 is a portion constituting the display unit of the combination meter 1, and the dial plate 3 is printed with a design such as a scale of each meter. The pointer 4 is arranged on the surface side of the dial 3 and indicates vehicle information such as a vehicle speed and an engine speed.

  The circuit board 5 is disposed on the back side of the dial 3. Various components such as a motor 6 that rotates the pointer 4, a light source 7 that illuminates the dial 3, and a controller 8 that controls the motor 6 and the light source 7 are mounted on the circuit board 5. Furthermore, a motor 13 for opening and closing a combiner 10 described later is also mounted on the circuit board 5.

  The control unit 8 acquires measured values of vehicle information such as vehicle speed and engine speed from the sensor, and controls the motor 6 so that the pointer 4 indicates the acquired measured values. The control unit 8 controls the head-up display described later in addition to the control of the combination meter 1. In addition, you may provide the control part which controls the combination meter 1, and the control part which controls a head-up display separately.

  The case 2 has an opening formed so as to face the driver's seat space, and a front cover 9 made of a transparent resin is disposed so as to close the opening. The front cover 9 is arranged such that the upper end 9a is retracted to the back side (the front windshield 101 side of the vehicle) rather than the lower end 9b. The display of the combination meter 1 (display of the dial plate 3) is visible through the front cover 9.

  The vehicle is equipped with a head-up display that displays a virtual image of various information in a space above the combination meter 1. Specifically, the head-up display includes a combiner 10, a rotating shaft 11, a gear 12, a motor 13, a HUD unit 14, and the control unit 8 described above.

  The combiner 10 is made of a transparent material such as acrylic resin, receives the light of the display image emitted from the HUD unit 14, and reflects the light of the display image to the driver D side so as to be in front of the driver D. It is a transparent plate that displays a virtual image (for example, in front of the windshield 101).

  For example, the combiner 10 is formed in a quadrangular shape when viewed from the front. The size of the combiner 10 is, for example, the same as or slightly smaller than the front cover 9 (see FIG. 2). That is, the combiner 10 is formed in a size that covers most of the front cover 9 when placed on the surface of the front cover 9 as shown in FIG. For example, the combiner 10 can be 50% or more of the size of the front cover 9. The combiner 10 may have any size, that is, it may be smaller or larger than the front cover 9.

  The combiner 10 is provided so that opening and closing is possible in the surface side of the front cover 9, as shown in FIGS. Specifically, as shown in FIG. 2, the combiner 10 is disposed so as to cover the surface of the front cover 9 (the surface on the driver D side) when not in use. In FIG. 1, the state when the combiner 10 is not used is indicated by a broken line portion 10 '. As shown in FIG. 2, when the combiner 10 is in the non-use position, the first end portion 10 a of the combiner 10 is positioned on the upper end 9 a (see FIG. 1) side of the front cover 9. Further, the second end portion 10 b of the combiner 10 that faces the first end portion 10 a is located on the lower end 9 b side of the front cover 9. Further, the third end portion 10 c that is the left end of the combiner 10 is located on the left end 9 c side of the front cover 9. Further, the fourth end portion 10 d that is the right end of the combiner 10 is located on the right end 9 d side of the front cover 9.

  The combiner 10 may be disposed so as to contact the front cover 9 when in the non-use position, or may be disposed at a distance from the surface of the front cover 9 (that is, non-contact). good.

  The combiner 10 is provided so as to be movable between the state of the unused position in FIG. 2 (state of the broken line portion 10 ′ in FIG. 1) and the state of the used position in FIG. 3 (state of the solid line portion 10 in FIG. 1). It is done. Specifically, the rotary shaft 11 is connected to the first end portion 10 a of the combiner 10. The rotating shaft 11 is provided in a shape facing the left-right direction of the vehicle at a position adjacent to the upper end 9a of the front cover 9 or at a position above the upper end 9a. FIG. 1 shows an example in which the rotating shaft 11 is located above the upper end 9a. Further, FIG. 1 shows an example in which the rotating shaft 11 is arranged in the case 2 of the combination meter 1.

  A gear 12 is connected to the rotating shaft 11. A gear 13 a (hereinafter referred to as a motor gear) is connected to the rotation shaft of the motor 13, and the motor gear 13 a and the gear 12 connected to the rotation shaft 11 are engaged with each other.

  The motor 13 is configured to be rotatable in the forward direction and the opposite direction. When the motor 13 rotates in the forward direction when the combiner 10 is in the non-use position, the rotating shaft 11 rotates counterclockwise on the paper surface of FIG. Due to the rotation of the rotating shaft 11, the combiner 10 rises above the front cover 9 from a non-use position that covers the front cover 9. At this time, the second end portion 10 b of the combiner 10 is located above (higher position) than the upper surface of the instrument panel portion 100. That is, at least a part of the combiner 10 moves (rotates) to a use position where it rises above the upper surface of the instrument panel 100. In other words, the combiner 10 rises up so as to face the space where the face of the driver D is located. Note that the standing angle of the combiner 10 is adjusted in advance so as to display a virtual image in a desired space (that is, the front space of the driver D).

  On the other hand, if the motor 13 rotates in the reverse direction when the combiner 10 is in the raised use position, the rotating shaft 11 rotates clockwise on the paper surface of FIG. Due to the rotation of the rotating shaft 11, the combiner 10 moves from the raised use position to the non-use position that covers the front cover 9.

  The HUD unit 14 (HUD is an abbreviation for head-up display) is a portion that emits a display image toward the combiner 10 in a raised state. Specifically, the HUD unit 14 is disposed closer to the driver's seat than the combination meter 1 (front cover 9). Further, the HUD unit 14 is disposed below the lower end 9 b of the front cover 9. The instrument panel unit 100 includes an overhanging portion 100b that projects from the lower side of the portion where the combination meter 1 is disposed to the driver's seat side. A housing space 100c is formed in the projecting portion 100b, and the HUD unit 14 is housed in the housing space 100c.

  The HUD unit 14 forms a display image, emits the light of the formed display image, and a light reflection unit (mirror) that reflects the light of the display image emitted from the display unit 15 to the combiner 10 side. 16 and a housing 17 for housing them. The display unit 15 is a fluorescent display tube (VED) in which a display and a light source are integrated, a liquid crystal display (LCD) in which the display and the light source are separated, and the like. In addition, the display unit 15 is electrically connected to the control unit 8 of the circuit board 5 by wiring 18.

  The light from the HUD unit 14 strikes the surface of the combiner 10 on the driver D side and is reflected on the driver D side. Due to this reflected light, a virtual image is displayed closer to the windshield 101 than the combiner 10.

  The control unit 8 also controls the head-up display as described above. Specifically, the control unit 8 monitors on / off of the power switch 110 (ignition power source or ACC power source (accessory power source)) of the vehicle. Then, based on the fact that the power switch 110 is turned on from off, the control unit 8 rotates the motor 13 in the forward direction and raises the combiner 10. The controller 8 keeps the combiner 10 in a raised state while the power switch 110 is on.

  Further, based on the fact that the power switch 110 is turned off from the on state, the control unit 8 rotates the motor 13 in the reverse direction to place the combiner 10 on the front cover 9. The control unit 8 and the motor 13 correspond to the control means of the present invention.

  Further, the control unit 8 controls the display unit 15 to display a virtual image corresponding to the scene through the combiner 10 when the combiner 10 is in the raised state. The virtual image according to the scene is, for example, the display of the combination meter 1 (for example, the vehicle speed), or the display performed by the navigation device when the navigation device is mounted on the vehicle (for example, in which direction at the next intersection Or an arrow indicating whether it should be done).

  Hereinafter, the effect of this embodiment will be described. In the present embodiment, the combiner 10 is provided so as to be movable between a non-use position that covers the surface of the front cover 9 and a use position that rises above the front cover 9. Therefore, the combiner 10 is provided inside the instrument panel 100. Space for installation can be eliminated. Further, it is possible to eliminate the need for making a hole for installing the combiner on the upper surface of the instrument panel unit 100. Thereby, while being able to suppress that the design of the instrument panel part 100 becomes complicated, the deterioration of the design property of the instrument panel part 100 can be suppressed.

  Further, by adopting a configuration in which the combiner 10 is placed on the front cover 9 when not in use, it is possible to easily secure the installation space for the combiner 10 when not in use even with a larger combiner 10. In other words, a larger combiner 10 can be employed. Specifically, for example, a combiner 10 having a size equivalent to that of the front cover 9 can be employed. By employing the large combiner 10, the display area of the virtual image can be enlarged, or the virtual image can be displayed at a higher position, so that the visibility of the virtual image can be improved.

  Further, when the vehicle is not used (when the power switch 110 is turned off), the combiner 10 is placed on the front cover 9 so that the appearance inside the vehicle compartment can be improved. It can suppress that the driver | operator D contacts the combiner 10 at the time of boarding / alighting of a vehicle. Further, the combiner 10 can be protected from dust and the like.

  Further, when the vehicle is in use (when the power switch 110 is turned on), the combiner 10 is in a raised state, so that it is possible to avoid hiding the display of the combination meter 1 by the combiner 10.

  Further, since the virtual image is displayed at a position higher than the display of the combination meter 1 through the combiner 10 when the combiner 10 is in the raised state, the driver D does not move the line of sight downward. Various information indicated by can be visually recognized, that is, various information can be easily visually recognized.

  In addition, since the combiner 10 is automatically opened and closed by the motor 13, the operation load on the driver D can be reduced.

  In addition, this invention is not limited to the said embodiment, A various change is possible to the limit which does not deviate from description of a claim. For example, although the example which opens and closes a combiner automatically with a motor was shown in the said embodiment, the structure which opens and closes a combiner manually may be employ | adopted. Thereby, since the motor can be omitted, the configuration of the head-up display can be simplified. Alternatively, a motor may be used when the combiner is raised, and it may be manually performed without using a motor when the combiner is lowered on the front cover. According to this, the motor control at the time of turning down the combiner can be omitted.

  Further, the emission of light to the combiner by the HUD unit may be performed from the ceiling surface side of the vehicle.
