Description

Display device

The present invention relates to a display device.

In recent years, for example, a so-called head-up display has begun to be installed near the driver's seat of a vehicle. The head-up display is a display device that displays image information such as own vehicle information, road information, and navigation information on a translucent display member called an image combiner (hereinafter also simply referred to as a combiner).

The head-up display displays, for example, driving support information as described above as a virtual image in front of the windshield. The driving support information is visually recognized by the driver over the scenery in front of the vehicle. Therefore, the head-up display can provide the driving support information to the driver with little movement of the driver's line of sight.

For example, Patent Document 1 discloses a vehicle having a combiner moving mechanism that raises and lowers a combiner between a deployment position and a storage position by performing a bending operation or an extension operation of a link mechanism including a combiner holder and a rotating arm. A display device is disclosed.

JP 2014-205376

The head-up display is mounted, for example, in a form embedded in the dashboard of the vehicle. There are many dimensional constraints in vehicles. For example, in the display apparatus for vehicles like patent document 1, the rotation mechanism is used for the movement of a combiner, and a movement mechanism occupies a big field. For this reason, the apparatus itself is increased in size, and there is a problem that it cannot be installed in an installation place with dimensional restrictions.

Also, for example, it is considered that troubles often occur because the combiner of the head-up display is exposed to the outside. Therefore, for example, in order to increase the ease of maintenance, it is desirable that the combiner can be replaced without disassembling the entire head-up display when a malfunction occurs in the combiner.

The present invention has been made in view of the above points. For example, the combiner can be quickly deployed, the position of the combiner at the deployed position can be finely adjusted, and the size can be reduced. Another object is to provide a display device that can facilitate replacement of a combiner.

The invention according to claim 1 is a housing having a pair of side plate portions opposed to each other, a drive member provided movably along at least one of the pair of side plate portions, and having a cam structure, A driven member that has a drive pin that engages with the cam structure and is movable with respect to the housing as the drive member moves; and a display structure that is detachably fixed to the driven member; The display device is characterized by comprising:

The invention according to claim 7 is a display structure including a housing, a translucent display member and a holding member that holds the display member and has a plurality of detachable portions, and the display structure. A moving mechanism that is attached and detached by the plurality of attaching and detaching portions and a part of which is housed in the housing, wherein the moving mechanism moves the display structure to the first position and the second position. When the display structure is in the first position, one of the plurality of attachment / detachment portions is exposed from the housing, and the other attachment / detachment portion of the plurality of attachment / detachment portions is moved. The display device is exposed from a housing when the display structure is in the second position.

Hereinafter, embodiments of the present invention will be described in detail. In the following description, a head-up display (HUD) having a combiner as a display unit will be described as an example of the display device.

[Overall structure]
FIG. 1 is a perspective view of the display device 10 according to the first embodiment in a display operation state (when the combiner is unfolded). FIG. 2 is a perspective view of the display device 10 in a non-display operation state (when the combiner is stored). The display device 10 is mounted on a moving body such as an automobile. For example, when mounted on an automobile, the display device 10 is mounted in a dashboard, for example.

The housing 11 has a plate-shaped top plate portion TP. A substantially rectangular opening OP is formed in the top plate portion TP. Further, the housing 11 has a pair of plate-like side plate portions SP extending from a side portion facing the top plate portion TP perpendicular to the extending direction of the top plate portion TP and facing each other.

In the following description, the direction along the line of intersection of the plate surface S of the top plate portion TP and the plate surface T of the side plate portion SP will be described as the depth (front-rear) direction (X-axis direction). Further, the direction perpendicular to the plate surface T of the side plate portion SP will be described as the width direction (Y-axis direction). The direction perpendicular to the plate surface S of the top plate TP will be described as the height (up and down) direction (Z-axis direction).

An image combiner unit (hereinafter referred to as a combiner unit) 13 as a display member is a unit having a plate-like combiner member 13A having translucency. The plate surface of the combiner member 13A is convexly curved in one direction (the arrow PD direction in the figure). For example, the combiner member 13 A is configured to form a virtual image in the convex-side space region when irradiation light enters from the concave-surface side.

As shown in FIG. 1, in the display operation state, the combiner unit 13 is in a state of protruding from the space inside the housing 11, that is, between the side plate portions SP. That is, the combiner unit 13 is in the deployed position. As shown in FIG. 2, the combiner unit 13 is accommodated in the combiner casing 11, that is, in the space between the side plate portions SP in the non-display operation state. That is, in the non-display operation state, the combiner unit 13 is in the storage position in the space formed between the two side plate portions SP.

More specifically, for example, the combiner unit 13 is stored in the storage position in the housing 11 before the display device 10 is turned on (before the automobile engine is started or before the ignition is turned on). Thereafter, when the power of the display device 10 is turned on, the combiner unit 13 rotates and is placed at the unfolded position. The combiner unit 13 is rotatably supported with respect to the side plate portion SP, and rotates between the storage position and the deployed position.

Fig. 3 shows an enlarged view of the combiner unit 13. As shown in FIG. 3, the combiner member 13A is fixedly held by a holding member 13B. The combiner member 13A and the holding member 13B are fixed by, for example, screwing. The combiner member 13A and the holding member 13B are referred to as a display structure.

In the following description, the direction toward the convex of the combiner member 13A in the display operation state (in the direction of the arrow PD in the figure) is assumed to be the front of the display device 10 and vice versa. In the display operation state, the direction of the tip of the combiner member 13A as viewed from the holding member 13B is described as being above the display device 10 and vice versa. For example, when the display device 10 is mounted in the dashboard of the moving body, the windshield of the moving body (for example, an automobile) exists in front of the display device 10, that is, in the direction of the arrow PD in the drawing. In addition, it is assumed that the passenger of the moving body looks at the combiner unit 13 from the rear side of the display device 10.

In the holding member 13B, four screw insertion holes HA as first through holes penetrating the holding member 13B in the front-rear direction at the deployment position of the combiner unit 13 are formed side by side in the width direction. The screw insertion hole HA is formed with a step so as to be narrowed by one step toward the rear, and the head of the inserted screw comes into contact with the step.

The driven member 13C is a member fixed to the holding member 13B by screws. On each side surface of the driven member 13C, a support pin AP as a supported portion supported rotatably about one rotation axis with respect to the side plate portion SP (see FIGS. 1 and 2), A combiner pin CP is formed as a drive pin that slides and is guided by a cam structure formed in a moving mechanism provided along the side plate portion SP.

FIG. 4 shows an exploded perspective view in which the combiner member 13A, the holding member 13B, and the driven member 13C are separated. As shown in FIG. 4, the holding member 13 B is formed with a protrusion PR that protrudes rearward from the holding member 13 B. Both end surfaces in the width direction of the convex part PR are contact surfaces AS1.

In the convex part PR, four screw insertion holes HB are formed side by side in the width direction as second through holes penetrating the convex part PR in the vertical direction at the deployment position of the combiner unit 13. That is, the screw insertion hole HA and the screw insertion hole HB extend at an angle to each other. In other words, the screw insertion hole HA extends along the direction 1, and the screw insertion hole HB extends at an angle with respect to the direction 1.

The screw insertion hole HB is formed with a step so as to be narrowed one step downward, and the head of the inserted screw is in contact with the step. The screw insertion hole HB is formed to be inclined rearward. That is, the screw insertion hole HB extends upward in a direction away from the plate surface of the combiner member 13A. In other words, the screw insertion hole HB extends in a direction away from the plate surface of the combiner member 13A from one end fixed to the holding member 13B of the combiner member 13A toward the other end, which is the tip.

Also, the projection PR is formed with three projections AC that protrude downward from the projection PR in the width direction.

The driven member 13C is formed with a recess CV that is recessed downward. The concave portion CV extends in the width direction, and an abutting surface AS2 facing in the width direction is formed. That is, the recess CV has a contact surface AS2 that is a pair of surfaces facing each other.

Further, the concave portion CV has a shape corresponding to the convex portion PR. For example, the concave portion CV has a shape complementary to the convex portion PR. That is, when the holding member 13B and the driven member 13C are combined, the convex part PR is fitted into the concave part CV. Further, when the holding portion 13B and the driven member 13C are combined, each of the contact surfaces AS1 and each of the contact surfaces AS2 comes into contact.

The driven member 13C is formed with a screw hole SHA as a first screw hole formed at a position matching the screw insertion hole HA when the holding portion 13B is combined with the driven member 13C. Inside the screw hole SHA, a female screw corresponding to the screw thread of the screw inserted from the screw insertion hole HA is formed. Four screw holes SHA are provided corresponding to the screw insertion holes HA.

In the present embodiment, of the four screw holes SHA, two at the center have an opening in the front surface of the driven member 13C and terminate in the driven member 13C. Of the four screw holes SHA, two at both ends penetrate from the front surface to the lower surface of the driven member 13C.

The bottom surface of the recess CV is formed with a screw hole SHB as a second screw hole formed at a position that matches the screw insertion hole HB when the holding member 13B is combined with the driven member 13C. The screw hole SHB penetrates the driven member 13 C in the vertical direction at the deployment position of the combiner unit 13. Inside the screw hole SHB, a female screw corresponding to the screw thread of the screw inserted from the screw insertion hole HB is formed.

As described above, the screw hole SHA extends in the front-rear direction at the deployment position of the combiner unit 13, and the screw hole SHB extends in the vertical direction at the deployment position of the combiner unit 13. In other words, the driven member 13C extends with a screw hole SHA extending along the direction 1 in a plane perpendicular to the rotation axis of the support pin AP and with an angle with the direction 1 in the plane. Screw holes SHB.

As with the screw insertion hole HB, the screw hole SHB extends upward in a direction away from the plate surface of the combiner member 13A. That is, when the holding member 13B and the driven member 13C are combined, a screw is inserted into the screw insertion hole HB from an oblique rear side. Therefore, in the insertion of the screw into the screw insertion hole HB and the subsequent screwing, an instrument such as a screwdriver that rotates the screw is prevented from interfering with the combiner member 13A.

Three through holes RH are formed side by side in the width direction on the bottom surface of the recess CV. The through hole RH is formed at a position corresponding to the protrusion AC, and penetrates the driven member 13 C in the vertical direction at the deployment position of the combiner unit 13. That is, when the holding portion 13B is combined with the driven member 13C, the protrusion AC is inserted into the through hole RH and is fitted therein.

As described above, the holding member 13B is fixed to the driven member 13C by screwing. Therefore, the display structure including the combiner member 13A and the holding member 13B and the driven member 13C can be easily detached.

Further, as described above, when the holding portion 13B and the driven member 13C are assembled, screws are inserted into the screw insertion holes HA and the screw holes SHA, and the screw insertion holes HB and SHBs and are fastened. Further, the convex part PR fits into the concave part CV, and the contact surfaces AS1 and AS2 contact each other.

Thereby, the holding portion 13B is restrained with respect to the driven member 13C in the front-rear direction which is the axial direction of the screw by the screw inserted into the screw insertion hole HA and the screw hole SHA. Further, the holding portion 13B is restrained in the vertical direction, which is the axial direction of the screw, by the screw inserted into the screw insertion hole HB and the screw hole SHB with respect to the driven member 13C. Furthermore, the holding member 13B is restrained in the width direction by the contact of the contact surfaces AS1 and AS2 with respect to the driven member 13C.

As described above, the holding portion 13B is restrained in the vertical direction, the front-rear direction, and the width direction with respect to the driven member 13C. Therefore, the coupling between the holding portion 13B and the driven member 13C is very strong three-dimensionally in the display device 10 with respect to the forward / backward movement, the vertical movement, and the left / right movement.

Further, since the projection PR fits into the recess CV and the projection AC fits into the through hole RH during assembly, the holding portion 13B is driven to the driven member before the holding portion 13B is screwed to the driven member 13C. It becomes possible to position at the position after assembly with respect to 13C. This facilitates positioning during screwing during assembly and facilitates assembly.

[Movement mechanism]
Next, the structure of the side plate portion SP of the housing 11 and the moving mechanism that moves the combiner unit 13 will be described.

FIG. 5 is an exploded perspective view of the moving mechanism formed on the side plate portion SP of the display device 10. The moving mechanism is provided along at least one of the pair of side plate portions SP, and engages with the combiner pin CP of the combiner unit 13, that is, engages with each other and can move relative to each other, and is a combiner that is a display member. The unit 13 is moved. The moving mechanism may be provided symmetrically on both the pair of side surface portions SP.

The transmission gear 15 is attached to a shaft SH that penetrates the inner plate 17 and is rotatably supported by the inner plate 17. The shaft SH is rotated by a drive unit (not shown) that is a motor such as an electric motor. The transmission gear 15 rotates with the rotation of the shaft SH.

The moving mechanism is disposed on the inner side of the side plate SP (see FIG. 1 or FIG. 2) and is disposed on the outer side of the inner plate 17 which is a longitudinal plate disposed in parallel with the side plate SP. It consists of a slide member 19 as a drive member and an outer plate (not shown) having the same outer shape as the inner plate.

The moving mechanism may include a driven member 13C. In this case, it can be said that the display structure including the combiner member 13A and the holding member 13B and the moving mechanism are detachably attached. That is, it can be said that the display structure and the moving mechanism are detachably attached by a plurality of attachment / detachment portions including screw holes SHA and SHB between the driven member 13C and the holding member 13B. Further, the moving mechanism may include a driven member 13C and a slide member 19 engaged therewith.

1 and 2, the case where the moving mechanism including the driven member 13 C and the slide member 19 is completely accommodated in the housing 11 is illustrated as an example. However, at least a part of the moving mechanism including the driven member 13C and the slide member 19 may protrude outside the housing 11 through the opening OP.

That is, when the moving mechanism includes the driven member 13C and the slide member 19 engaged with the driven member 13C, a part of the moving mechanism, for example, the driven member 13C may be out of the casing 11. In other words, it is only necessary that a part of the moving mechanism is accommodated in the housing 11.

The inner plate 17 is provided with a cylindrical slide pin SLP extending perpendicular to the plate surface of the inner plate 17. Two slide pins SLP are arranged side by side in the front-rear direction of the display device 10. Although not shown, the outer plate is formed with holes into which the respective tips of the slide pins SLP are fitted.

The inner plate 17 is provided with a pin support hole APH penetrating the inner plate in the width direction. The support pin AP is inserted into the pin support hole APH so as to be rotatable around a rotation axis along the width direction. That is, the support pin AP is inserted into the pin support hole APH and is supported to be rotatable with respect to the inner plate 17.

A rack gear LG is formed on the lower surface of the slide member 19. The rack gear LG is engaged with the transmission gear 15. The slide member 19 is provided with a slide rail SR extending in the longitudinal direction of the slide member 19, that is, in the direction of sliding movement of the slide member 19. Two slide rails SR are arranged side by side along the slide movement direction of the slide member 19. Each of the slide rails SR penetrates the slide member 19 in the width direction of the display device 10.

Each of the slide pins SLP of the inner plate 17 is slidably inserted into a slide rail SR provided on the slide member 19. That is, the slide pin SLP serves as a guide pin for so-called slide movement of the slide member 19. Accordingly, the slide member 19 is provided so as to be slidable (slidable) along the side plate portion SP (see FIGS. 1 and 2), and when the transmission gear 15 with which the rack gear LG is engaged rotates, the slide rail SR. It slides (slides) along the extending direction.

A cam structure CM is formed on the surface of the slide member 19 on the inner plate 17 side. The cam structure CM is slidably engaged with or in contact with the combiner pin CP of the combiner unit 13. That is, the cam structure CM is a cam that drives the combiner pin CP along a path formed along a part of an arc centered on the support pin AP.

The combiner unit 13 is urged rearward (in a rotational direction from the deploying position of the combiner unit 13 toward the storage position) by a spring or the like (not shown). Accordingly, the combiner pin CP moves along the cam surface of the cam structure CM while being pressed against the cam structure CM by the biasing force.

The inner plate 17 is further formed with a through-hole CR extending in a curved shape in the longitudinal direction of the inner plate 17. The through hole CR is formed along a part of an arc centering on the support pin AP of the combiner unit 13 that is rotatably supported with respect to the side plate portion SP. The through hole CR passes through the inner plate 17. The combiner pin CP passes through the through hole CR, reaches the cam structure CM of the slide member 19, and is engaged with, or in contact with, the cam structure CM.

FIG. 6 shows a perspective view of the slide member 19 as seen from the lower outside in the width direction. As shown in FIG. 6, the lower surface of the slide member 19, which is a surface perpendicular to the plate surface of the side plate portion SP, extends along the slide direction of the slide member 19 in the longitudinal direction of the slide member 19, that is, the front-rear direction. A concave portion RC is formed.

The recess RC is arranged on the outer surface of the slide member 19 on the lower surface of the slide member 19, in other words, on the surface opposite to the surface facing the inner plate 17, in other words, the region along the surface on the outer plate side not shown. Has been. That is, the slide member 19 has a corner portion that is cut out in a columnar shape along the outer surface of the slide member 19 on the lower surface, and the notched portion is a recess RC. In other words, the recess RC is formed so as to be opened outward and downward in the width direction of the slide member 19.

The rack gear LG described above is formed on the bottom surface BS in the vertical direction of the display device 10 of the recess RC. That is, the rack gear LG is formed at the bottom of the recess RC. Furthermore, in other words, the rack gear LG is formed on another surface of the lower surface of the slide member 19, that is, a surface recessed upward from the lower surface along the inner surface.

The cam structure CM is formed by a recess disposed on the inner surface of the slide member 19. That is, in the slide member 19 of the present embodiment, the cam structure CM is formed in the inner region in the width direction of the slide member 19, and the rack gear LG is formed in the outer region.

The cam structure CM has a first cam portion CM1 as a first inclined portion extending substantially perpendicularly to the longitudinal direction of the slide member 19, that is, the moving direction of the slide member 19. In other words, the cam structure CM includes the first cam portion CM1 having a steep inclination with respect to the moving direction of the slide member 19. The first cam portion CM1 reaches the lower surface of the slide member 19. That is, the first cam portion CM1 and the rack gear LG are arranged so as to overlap each other when viewed from the width direction, in other words, the direction perpendicular to the plate surface of the side plate portion SP. Further, the slide member 19 and the transmission gear 15 are arranged so as to overlap each other when viewed from the width direction, in other words, the direction perpendicular to the plate surface of the side plate portion SP.

The cam structure CM has a second cam portion CM2 as a second inclined portion formed continuously from the end portion of the first cam portion CM1. The second cam portion CM 2 extends in the longitudinal direction of the slide member 19. The second cam portion CM2 has an inclination different from that of the first cam portion, and is inclined forward and gently upward with respect to the moving direction of the slide member 19. Specifically, the angle of the first cam portion CM1 with respect to the slide movement direction of the slide member 19 is larger than the angle of the second cam portion CM2 with respect to the slide movement direction.

The escape portion ES is a recess that extends from the end portion of the second cam portion CM2, that is, from the front end portion to the front end surface of the slide member 19 forward. The escape portion ES is a recess that is recessed downward in a direction perpendicular to the lower surface BS. The escape portion ES is an escape portion for the support pin AP. That is, the escape portion ES is formed so that the support pin AP and the slide member 19 do not interfere when the slide member 19 slides.

As described above, the amount of movement of the combiner pin CP with respect to the amount of movement of the slide member 19 is changed by forming the cam structure CM from the first cam portion CM1 and the second cam portion CM2 having a steep slope. Can do. Accordingly, when the combiner unit 13 is moved from the storage position to the deployed position without changing or greatly changing the moving speed of the slide member 19, the slide unit 19 is quickly rotated to reach the deployed position. When adjusting the angle, it is possible to rotate it finely and slowly. Moreover, since the amount of rotation of the combiner per rotation of the motor can be reduced during angle adjustment, the adjustment accuracy of the rotation position of the combiner unit 13 can be improved.

Further, as described above, by forming the rack gear LG on the bottom surface of the recess RC, the cam structure CM and the rack gear LG can be formed so as to overlap each other when viewed from the width direction. That is, the slide member 19 and the transmission gear 15 can be formed so as to overlap each other when viewed from the width direction. By doing so, it is possible to reduce the vertical dimension of the entire display device 10 while maintaining the region where the cam structure CM is formed as large as possible in the vertical direction. Thereby, the display device 10 can be downsized and made compact.

Further, by forming the rack gear LG on the bottom surface of the recess RC, the position of the slide member 19 can be lowered downward by the dimension in the height direction of the recess RC. This also makes it possible to reduce the height of the display device 10 and make it compact.

In this case, in order to prevent interference between the shaft SH to which the transmission gear 15 is attached and the slide member 19, the dimensions of the slide RC of the recess RC in the direction perpendicular to the slide direction of the slide member 19 and the width direction of the display device 10 are set. The value is preferably smaller than the value obtained by subtracting the radius of the shaft SH from the radius of the transmission gear 15.

[Transition from non-display operation state to display operation state]
Next, transition from the non-display operation state to the display operation state will be described with reference to FIGS. 7 to 9 which are side views of the display device 10.

FIG. 7 shows a side view of the display device 10 in a non-display operation state. In the non-display operation state, the slide member 19 is at the foremost position in the direction along the slide rail SR. At this time, the combiner pin CP is in the foremost position along the through hole CR. That is, the combiner pin CP is arranged almost directly below the support pin AP, and the combiner unit 13 is in a sleeping state, that is, in the storage position.

As can be seen from FIGS. 3 and 7, in this non-display operation state, the portion of the holding member 13B where the screw insertion hole 13HA is formed is accessible from the opening OP. Therefore, only the screw insertion hole HA of the screw insertion hole HA and the screw insertion hole HB is accessible from the opening OP. In other words, in the non-display operation state, the display structure is in the storage position that is the first position, and only the screw insertion hole HA is displayed upward in the direction of 1 among the screw insertion holes that are the detachable portions. It is exposed from the casing 11 of the apparatus 10.

From this state, the drive unit (not shown) is driven to rotate the shaft clockwise, and accordingly, the transmission gear 15 rotates clockwise, and the slide member 19 slides backward.

FIG. 8 shows a side view of the display device 10 during the transition from the non-display operation state to the display operation state. When the slide member 19 moves rearward, the combiner pin CP is moved rearward while engaging with the first cam portion CM1 of the cam structure CM (see FIG. 6). Further, the combiner pin CP moves upward as it moves backward. That is, the combiner pin CP moves rearward and upward along a movement path formed along a part of an arc centered on the support pin AP.

When the combiner pin CP moves rearward and upward, the combiner unit 13 rotates around the support pin AP and rises toward the deployed position.

FIG. 9 shows the display device 10 in the display operation state. When the slide member 19 moves rearward from the non-display operation state of FIG. 7 and the combiner pin CP moves upward along the movement path, and the combiner pin CP reaches the upper end of the first cam portion CM1. The combiner pin CP reaches the second cam portion CM2 and starts to contact the second cam portion CM. When the combiner pin CP reaches the second cam portion CM2, the combiner unit 13 reaches the unfolded position, and the display device 10 enters the display operation state.

As can be seen from FIGS. 4 and 9, in this display operation state, the portion where the screw insertion hole 13HB of the holding member 13B is formed is accessible from the opening OP. Therefore, only the screw insertion hole HB is accessible from the opening OP among the screw insertion hole HA and the screw insertion hole HB. In other words, in the display operation state, the display structure is in the unfolded position that is the second position, and only the screw insertion hole HB of the screw insertion hole that is the detachable portion is directed upward in the direction of 1. 10 housings 11 are exposed.

The combiner unit 13 is rotated by being driven by a drive unit that is normally driven by power supply from a moving body. Therefore, when the power supply is cut off in either the display operation state or the non-display operation state, only one of the screw insertion holes HA and HB can be accessed.

Thus, for example, when the display device 10 is mounted on an automobile and the engine is turned off in any posture, the engine is started or the electrical component is powered by an operation using the automobile key. If not supplied, only one screw insertion hole HA or HB can be accessed. Therefore, contrary to the intention of the owner of the automobile, it is possible to reduce the possibility that the display structure is removed and stolen by an object that does not have a key.

As described above, in the display device 10, it is impossible to simultaneously access each of the screw insertion holes HA and HB for attaching the display structure including the combiner member 13A and the holding member 13B to the driven member 13C. Specifically, in each of two different postures of the combiner unit 13, that is, two different postures of the display structure including the combiner member 13A and the holding member 13B, the screw insertion holes HA and HB are externally provided. You can only access one.

Therefore, when the display structure composed of the combiner member 13A and the holding member 13B is attached to or detached from the driven member 13C, the display structure does not undergo work in two postures of the display structure. Cannot be attached to or removed from 13C.

In the display operation state, the holding member 13B and the driven member 13C are housed in the housing 11, and only the combiner member 13A is exposed to the outside of the housing through the opening OP. Therefore, in the display operation state, only the portion that can be used for image display by the display member is exposed outside the housing, and the height of the entire display device 10 in the display operation state is minimized while maximizing the display area. It is possible to

As shown in FIG. 9, the combiner pin CP moves on the second cam portion CM2 by further moving the slide member 19 rearward from the state where the unfolded position has been reached. In accordance with the rearward movement of the slide member 19, the combiner pin CP moves further upward along the movement path, and the combiner unit 13 rotates.

As described above, the second cam portion CM2 has a gentler inclination than the first cam portion CM1 with respect to the moving direction of the slide member 19. Therefore, the amount of movement of the combiner pin CP with respect to the amount of movement of the slide member 19, that is, the amount of rotation of the motor of the drive unit, is smaller than when the combiner pin CP is in contact with the first cam portion CM1. That is, when the combiner unit 13 is brought from the storage position to the deployed position as the slide member 19 moves, the combiner unit 13 rotates more slowly and gradually than the so-called deployed position.

This operation makes it possible to perform an adjustment operation for adjusting the angle of the combiner unit 13 at the unfolded position. Further, as described above, this slow rotation can be achieved without changing the moving speed of the slide member 19 from the time of deployment. In this adjustment operation, the amount of movement of the slide member 19, that is, the amount of rotation of the motor of the drive unit, that is, the amount of rotation of the combiner unit 13 with respect to the amount of rotation of the drive gear MG is smaller than that during deployment.

This makes it possible to adjust the rotational angle position of the combiner unit 13 with high accuracy. Further, for example, it is possible to increase the positioning accuracy of the rotation angle position of the combiner unit 13 without changing the accuracy of the motor drive amount control.

Furthermore, without changing the moving speed of the slide member 19, that is, without changing the rotational speed of the motor of the drive unit, that is, the rotational speed of the drive gear MG, the rotational speed of the combiner unit 13 is increased at the time of deployment, and thereafter adjusted. The operation can be slow. That is, according to the display device 10, it is possible to bring the combiner unit 13 from the stored state to the expanded state quickly. Further, since it is not necessary to change the rotation speed of the motor of the drive unit during the turning operation of the combiner unit, it is possible to improve the operation stability of the drive unit. Further, it is possible to suppress an unnatural operation of the combiner unit that occurs when the rotation speed of the motor of the drive unit changes.

In the above embodiment, the case where the display device 10 includes the housing 11 has been described as an example. However, the housing 11 may be integrated with a part of the automobile on which the display device 10 is mounted. For example, when the housing 11 is mounted in a dashboard of an automobile, the dashboard may be integrated with the housing 11. Specifically, for example, an opening corresponding to the opening OP of the housing 11 described above may be formed on the dashboard, and the combiner unit 13 may protrude on the dashboard from the opening.

In this case, for example, in the non-display operation state, the display structure is in the storage position which is the first position, and only the screw insertion hole HA among the screw insertion holes which are the detachable portions is directed upward in the direction of 1. It may be exposed from the opening of the dashboard.

Further, in the display operation state, the display structure is in the unfolded position which is the second position, and only the screw insertion hole HB of the screw insertion hole which is the detachable portion is directed upward in the direction of 1. It is good also as exposing from the said opening part.

That is, the control unit 25 supplies a drive signal for moving the display structure by moving the slide member 19 via the output unit 29.

The output unit 29 can output an image signal including the image information to the light source LS that generates irradiation light including the image information that is irradiated to the combiner member 13A of the combiner unit 13 in the unfolded state. Also good.

The data communication unit 31 transmits / receives various data to / from other devices by wireless communication such as Wi-Fi (registered trademark) or Bluetooth (registered trademark) or wired communication. The data communication unit 31 is a position specifying device such as a GPS (Global Positioning System) device or a device capable of specifying a position based on a base station of a mobile phone network, etc., which is mounted on a vehicle to which the display device 10 is attached. In addition, it can communicate with a sensor device SA including various sensors such as an acceleration sensor and a gyro sensor.

Further, the data communication unit 31 may be capable of receiving information from a vehicle-mounted camera CA mounted on the automobile 10 or a distance measuring device DM such as 3D-LiDAR or millimeter wave radar. The SA, the in-vehicle camera CA, and the distance measuring device DM may be provided in the display device 10. In that case, information from the sensor device SA, the in-vehicle camera CA, and the distance measuring device DM may be transmitted directly to the control unit 25.

The control unit 25 can determine the position or running state of the vehicle based on information from the sensor device SA. That is, the control unit 25 acquires the position specifying information that is acquired by the sensor device SA and is information for specifying the position, and specifies the position of the display device 10 or the position of the automobile on which the display device 10 is mounted. It is possible.

In addition, for example, the data communication unit 31 communicates with a computer or the like mounted on the vehicle to which the display device 10 is attached, to determine whether the vehicle is in automatic operation, in other words, whether the vehicle is in automatic operation mode. Information may be receivable.

[2. Expansion storage operation routine]
Hereinafter, an unfolding and storing operation routine R1 executed in the control unit 25 in order to realize the unfolding and storing operation of the combiner unit 13 of the display device 10 according to the second embodiment will be described. In the following unfolding and storing operation routine R1, an operation in which the combiner unit 13 is expanded in the manual operation area and the combiner unit 13 is stored in the automatic operation area is realized. That is, according to the following deployment storage operation routine R1, the combiner unit 13 is deployed when moving from the automatic operation area to the manual operation area, in other words, when shifting from the automatic operation mode to the manual operation mode.

In the transition to the manual operation mode, the combiner unit 13A of the combiner unit 13 can display an operation or action to be taken by the driver, the ambient environment around the vehicle, and the like. By displaying these, when the automobile shifts from the automatic driving mode to the manual driving mode, the driver can smoothly start the manual driving operation.

For example, the unfolding and storing operation routine R1 is started when the power is supplied to the display device 10, and is repeatedly executed. The unfolding and storing operation routine R1 may be started when the ACC power supply of the mounted vehicle is turned on.

When the unfolding and storing operation routine R1 is started, the control unit 25 first determines in step S1 whether or not the vehicle on which the display device 10 is mounted is in an automatic operation, that is, in an automatic operation mode.

This determination may be made based on information indicating whether or not the current mode of the vehicle obtained by communication between the communication unit 31 and the vehicle on which the display device 10 is mounted is the automatic driving mode.

This determination is made by referring to the position specifying information acquired by the sensor device SA and the map information database 23A, based on whether or not the vehicle on which the display device 10 is mounted is located in the automatic driving area. Also good. For example, it may be determined that the vehicle is in the automatic driving mode when the vehicle is located in the automatic driving area. If it is determined in step S1 that the mode is not the automatic operation mode (step S1: NO), the unfolding and storing operation routine R1 is thereafter terminated.

When it is determined in step S1 that the automatic driving mode is set (step S1: YES), the control unit 25 determines whether or not the vehicle on which the display device 10 is mounted enters the manual driving area (step S2). This determination may be made by referring to the position specifying information acquired by the sensor device SA and the map information database 23A.

Further, this determination may be made based on whether or not the vehicle on which the display device 10 is mounted is located in the manual driving area at the time of determination. Further, this determination may be made based on whether or not the vehicle is in the vicinity of the manual operation area, for example, whether or not the vehicle is located in the buffer area between the manual operation area and the automatic operation area described above. .

If it is determined in step S2 that the automobile has entered the manual operation area (step S2: YES), the control unit 25 determines whether or not the combiner unit 13 is in the deployed position (see FIG. 1) (step S2). S3). This determination may be made based on an operation history of the motor MO and a sensor (not shown) that detects the position of the combiner unit 13.

If it is determined in step S3 that the combiner unit 13 is in the expanded state (step S3: YES), then the routine R1 is terminated and the combiner unit 13 is maintained in the expanded state. In step S3, when it is determined that the combiner is not in the unfolded state, that is, in the retracted state (step S3: NO), the control unit 25 transmits a drive signal to the motor MO to unfold the combiner unit 13 ( Step S4) Thereafter, the routine R1 ends.

If it is determined in step S2 that the vehicle is not in the manual operation area (step S2: NO), the control unit 25 determines whether or not the combiner unit 13 is in the deployed position (see FIG. 1). (Step S5). This determination may be performed based on a sensor (not shown) that detects the operation history of the motor MO and the position of the combiner unit 13 as in step S3.

If it is determined in step S5 that the combiner unit 13 is in the unfolded state (step S5: YES), the control unit 25 transmits a drive signal to the motor MO to store the combiner unit 13 (step S6). Routine R1 ends. If it is determined in step S5 that the combiner is not in the expanded state, that is, in the stored state (step S5: NO), then the routine R1 ends and the combiner unit 13 is maintained in the stored state.

As described above, in the routine R1, the control unit 25 can control the motor MO as the drive unit based on the position specifying information acquired by the sensor device SA.

According to the display device 10 having the controller 20, when the vehicle on which the display device 10 is mounted shifts from the automatic operation state to the manual operation state, the combiner unit 13 is brought into the unfolded state, thereby driving the vehicle. It is possible to provide information that contributes to the shift to manual operation.

Also, as described above in the first embodiment, the combiner unit 13 can be quickly deployed from the stored state. Accordingly, when the vehicle on which the display device 10 is mounted shifts from the automatic driving state to the manual driving state, the combiner unit 13 is quickly deployed to be in the display operation state, and the driver can quickly shift to manual driving. It is possible to provide useful information.

The various configurations and the like in the above-described embodiments are merely examples, and can be selected as appropriate according to the usage and the like.
