DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, a display device and a method for expanding the display device according to embodiments of the present disclosure will be described with reference to the drawings. Note that the configurations and combinations thereof in each embodiment are merely examples, and additions, omissions, substitutions, and other modifications of the configurations are possible as appropriate within the scope of the gist of the present invention.

[0010] First Embodiment FIG. 1 is a cross-sectional view showing a state in which the display 20 of the display device 1 according to the first embodiment is open, FIG. 2 is a front view of the display device 1 according to FIG. 1, FIG. 3 is a bottom view of the display device 1 according to FIG. 1, and FIG. 4 is a perspective view of the display device 1 according to FIG. 1. FIG. 5 is a cross-sectional view showing a state in which the display of the display device 1 according to the first embodiment is closed, and FIG. 6 is a perspective view of the display device 1 according to FIG. 5. In this embodiment, among the vertical directions (Y-axis direction), the direction toward the roof outer panel in the vehicle cabin is the upward direction, and the direction toward the floor surface in the vehicle cabin is the downward direction. Furthermore, the width direction of the vehicle (X-axis direction) is the left-right direction. These directions are merely examples and are not limited thereto. The definitions of these directions are the same for the subsequent figures unless otherwise specified. Note that the up-down-left-right directions of the display may correspond to the up-down-left-right directions of the image displayed on the display surface.

[0011] The display device 1 includes a base unit 10, a display 20, and a rotation mechanism 30. The base unit 10 is attached to a ceiling surface (hereinafter also referred to as roof lining) 41 inside the vehicle cabin. The rotation mechanism 30 rotatably holds the display 20. That is, the display 20 is attached to the roof lining 41 of the vehicle via the base unit 10 and the rotation mechanism 30. In this embodiment, the upper part of the base unit 10 is fixed to a structural member 42 extending in the vehicle width direction, thereby indirectly attaching the base unit 10 to the roof lining 41. The structural member 42 and the roof outer panel 43 are welded or bonded together.

[0012] The base unit 10 is a housing having side plates 11 and 12 standing on the left and right, side plates 13 and 14 standing on the front and back, a bottom plate 15 connected to the side plates 11, 13, and 14 and covering part of the bottom surface, and a top plate 16 covering the top side of the base unit 10. The base unit 10 houses a display 20 in an internal space surrounded by these side plates 11 to 14, bottom plate 15, and top plate 16.

[0013] The base portion 10 also has a left lower plate 111 provided along the lower end of the side plate 11 and an inner plate 112 erected on the left lower plate 111, and the side plate 11, the left lower plate 111, and the inner plate 112 together form a left side wall 17. Similarly, the base portion 10 has a right lower plate 121 provided along the lower end of the side plate 12 and an inner plate 122 erected on the right lower plate 121, and the side plate 12, the right lower plate 121, and the inner plate 122 together form a right side wall 18.

[0014] The base portion 10 is formed so that when the top panel portion 16 is fixed to a structural member 42 of the vehicle, the upper ends of the side panels 11 to 14 fit along the roof lining 41. The top panel portion of the base portion 10 has a bulge that protrudes above the roof lining 41, and is formed so as to accommodate the upper part of the display 20 when the display 20 is opened as described below.

[0015] The base unit 10 also includes a lid unit 19 that covers the underside of the base unit 10, behind the display 20. The lid unit 19 includes a generally flat lower plate 192, and rotation shafts 191 that protrude in the left-right direction from the left and right side edges are provided near the rear end of the lower plate 192. The rotation shafts 191 are inserted into bearings (shaft holes) 113, 114 provided in the side plates 11, 12 of the base unit 10, thereby rotatably holding the lid unit 19 relative to the base unit 10. The rotation mechanism is not limited to this, and may have any other configuration as long as it can rotatably hold the lid unit 19 relative to the base unit 10. The lid unit 19 also includes a torsion spring 193 between the lower plate 192 and the top plate 16. The torsion spring 193 is an example of an elastic member. When the cover 19 is rotated upward, the torsion spring 193 is compressed between the lower plate 192 and the top plate 16, and the lower plate 192 is pulled downward. With The elastic member is not limited to the torsion spring 193, but may be a spring of another shape, such as a coil spring or a leaf spring. The elastic member is also not limited to a spring, but may be other material such as rubber.

[0016] The cover 19 is formed so that, when rotated downward, the lower plate 192 fits along the lower ends of the side plates 11 and 12 of the base 10. An upright plate 190 is provided on the front edge of the lower plate 192 facing upward, and a passive part 194 is provided on the upper edge of the upright plate 190 and extends forward.

[0017] The display 20 is generally flat and electrically connected to the electronic devices on the vehicle side, and displays images by receiving power and video signals from the electronic devices. The configuration for displaying images on the display 20 is not particularly limited, and any known configuration can be used. The display 20 has bearing portions (shaft holes) 21, 22 on the left and right side surfaces, respectively. In addition, the display 20 has a blindfold plate 23 that closes the gap between the side panel 11 and the side surface of the display 20, and a blindfold plate 24 that closes the gap between the side panel 12 and the side surface of the display 20, both of which are provided along the side surfaces of the display 20.

[0018] The display 20 is rotatably held relative to the base unit 10 by inserting shafts 31 and 32, which are attached to the side plates 11 and 12 of the base unit 10 in the horizontal direction (X-axis direction), into bearings (shaft holes) 21 and 22. That is, in this embodiment, the bearings 21 and 22 and the shafts 31 and 32 constitute the rotation mechanism 30. Note that in this embodiment, the shafts 31 and 32 are provided on the base unit 10 side and the bearings (shaft holes) 21 and 22 are provided on the display 20 side, but it is also possible to provide the bearings on the base unit 10 side and the shafts on the display 20 side. In addition, the rotation mechanism is not limited to shafts and shaft holes, and may have another configuration as long as it can rotatably hold the display 20.

[0019] The rotation mechanism 30 can rotate the display 20 to a first position in which the display surface 25 faces in a direction along the roof lining 41, as shown in FIGS. 5 and 6. This state in which the display 20 is in the first position is also referred to as a state in which the display 20 is closed. At this time, the display 20 is almost entirely housed within the internal space of the base 10. In this case, the elastic force of the torsion spring 193 causes the lid 19 to be lowered to a position where the passive part 194 abuts against the top surface of the display 20. Hereinafter, this position will also be referred to as the first position.

[0020] Furthermore, the rotation mechanism 30 can rotate the display 20 to a second position in which the display surface 25 faces a predetermined viewing position (eye point), as shown in FIGS. 1 to 4 . That is, the rotation mechanism 30 holds the display 20 rotatably between the first position and the second position. This state in which the display 20 is in the second position is also referred to as an open state of the display 20. At this time, the display 20 rotates about the shafts 31 and 32 as the rotation axis (rotation center), and the lower end portion 201 is lowered and the upper end portion 202 is raised. Therefore, in the second position, the upper end portion 202 of the display 20 is accommodated in the bulging portion 209 of the base 10. That is, in the second position, the upper end portion 202 of the display 20 is disposed in the ceiling space 44 between the roof outer panel 43 and the roof lining 41 in the ceiling portion of the vehicle.

[0021] For example, when using the display device 1, the user manually pulls down the bottom end portion 201 of the display 20 or pushes up the top end portion 202. As a result, the display surface 25 of the display 20 is directed toward the viewing position (eye point) of the rear passengers, and the display 20 assumes the second posture. That is, the display device 1 is unfolded and ready for use. At this time, as shown in FIG. 1 , the top end of the display 20 pushes up the passive portion 194 of the lid portion 19, causing the lid portion 19 to rotate about the rotation axis 191 and move to the second position. Note that when the display 20 is closed, the lid portion 19, which is positioned in the first position, covers the passenger compartment side of the in-ceiling space 44 and prevents the rear passengers from seeing the in-ceiling space 44, thereby enhancing the aesthetic appearance of the display 20 when closed. On the other hand, when the display 20 is opened, the lid part 19 moves to a predetermined area 205 on the display surface side of the display, for example, to a second position that is out of the field of view when viewing the display surface 25 from a viewing position, so that the lid part 19 does not hide the display surface of the display 20.

[0022] The deployment of the display 20 does not necessarily have to be manual, but may be performed by a drive unit such as a motor or an actuator, which may move the display 20 from the first position to the second position. For example, when the passenger turns on the power of the display device, the drive unit may drive the rotation mechanism 30 to move the display 20 from the first position to the second position.

[0023] In this embodiment, the rotation axis (shafts 31, 32) of the display 20 is located near the center of the display 20 in the direction along the display surface 25 (the up-down direction of the display 20), and therefore the portion located above this rotation axis moves upward in the second position. The position of the rotation axis is not limited to this, and it may be located lower than the upper end in the up-down direction of the display 20. In this case, the closer the rotation axis is to the lower end of the display 20, the larger the upper end portion 202 that is accommodated in the intra-ceiling space 44 in the second position. For example, the upper end portion 202 that is accommodated in the intra-ceiling space 44 in the second position may be 1 / 2 to 1 / 4 of the display 20 in the up-down direction.

[0024] In this way, when the display device 1 of this embodiment is used, when the display 20 is in the second position, the upper end portion 202 is positioned in the ceiling space 44, so that the portion that protrudes below the roof lining 41 is reduced.

[0025] Figure 7 is a comparative example showing an example in which a display device 90 having a rotation axis 9X at the upper end of the display 91 is installed on the ceiling of a vehicle 80, and Figure 8 is a diagram showing an example in which the display device 1 of this embodiment is installed on the ceiling of a vehicle 80.

[0026] 7, in a display device 90 of the comparative example, when a display 91 is rotated from a closed state to an open state and a display surface 92 is directed toward eye point 81, most of the display 91 is located within a field of view 84 of a passenger (driver) sitting in the driver's seat when checking the rear of the vehicle through an inner mirror 82. For this reason, field of view 84 is blocked in an area 85 where the display 91 is located.

[0027] In contrast, in the display device 1 of this embodiment, as shown in Fig. 8, when the display 20 is opened, the upper end portion of the display 20 is accommodated in the ceiling space 44 between the roof lining 41 and the roof outer panel 43, so only the lower end portion 201 is within the driver's field of view 84. Therefore, in the display device 1 of this embodiment, the field of view 84 is blocked in a range 86 where the lower end portion 201 of the display 20 is located. In this way, the display device 1 of this embodiment can keep the range 86 that blocks the occupant's field of view 84 smaller than the range 85 of the comparative example.

[0028] Second Embodiment Fig. 9 is a cross-sectional view showing a state in which a display 20A of a display device 1A according to a second embodiment is open, Fig. 10 is a front view of the display device 1A according to Fig. 9, Fig. 11 is a bottom view of the display device 1A according to Fig. 9, and Fig. 12 is a perspective view of the display device 1A according to Fig. 9. Also, Fig. 13 is a cross-sectional view showing a state in which the display 20A of the display device 1A according to the second embodiment is closed, and Fig. 14 is a perspective view of the display device 1A according to Fig. 13.

[0029] This embodiment differs from the first embodiment in that lid portion 19A is connected to display 20A, and lid portion 19A moves from a first position to a second position as display 20A rotates. Since the other configurations are the same, the same elements are denoted by the same reference numerals, and a repeated description will be omitted.

[0030] As shown in FIG. 9 , lid portion 19A of this embodiment includes plate portion 197 disposed substantially horizontally in the first position, and front plate portion 198 hanging down from the front edge of plate portion 197. Cover portion 19A also includes shaft portion 195 on extension portion 199 extending downward from the front end portion. Cover portion 19A also includes engagement protrusion 196 at its rear end. Shaft portion 195 of lid portion 19A is supported by bearing 26 provided at the upper end portion of display 20A, connecting lid portion 19A to display 20A. Engagement protrusion 196 of lid portion 19A engages with cam groove 161 provided in side wall 160 of top plate portion 16 of base portion 10, and is movable along cam groove 161.

[0031] Moreover, the display 20A of this embodiment has a main body 203 including a display surface 25, and arm portions 204 extending in one direction from the left and right side portions of the main body 203. The arm portions 204 are provided lower than the upper end in the up-down direction of the main body 203, and extend in a direction perpendicular to the up-down direction and away from the main body 203. A bearing portion 21A is provided on an end (tip) 204A of the arm portion 204 that is not connected to the main body 203.

[0032] The display 20A is rotatably held relative to the base 10A by inserting a shaft 31A, which is attached to the side wall 160 of the top panel 16 in the horizontal direction (X-axis direction), into a bearing (shaft hole) 21A.

[0033] Figure 15 is a diagram showing the operation of lid portion 19A as display 20A is rotated. In Figure 15, State A shows the state in which display 20A is closed. At this time, plate portion 197 of lid portion 19A covers the underside of bulge portion 209 at approximately the same height as roof lining 41, and front plate portion 198 covers the internal space of base portion 10, flush with end surface 208 of display 20A.

[0034] 15, state B shows a state in which display 20A has begun to open. At this time, lid 19A is lifted upward as shaft 195 moves upper end portion 202 of display 20A, and engagement protrusion 196 moves along cam groove 161. When display 20A is further rotated and assumes a second position, lid 19A is moved to a second position out of predetermined region 205A, as shown in state C.

[0035] In this manner, in this embodiment, since the lid portion 19A can be provided near the roof lining 41, there is no need for the side plates 11, 12 of the base portion 10 to cover the sides of the lid portion 19A as in the first embodiment, and therefore the rear ends of the side plates 11, 12 can be cut out to make the rear portions of the side plates 11, 12 shorter than in the first embodiment. As a result, the display device 1A of this embodiment prevents the rear ends of the side plates 11, 12 from blocking the view of the occupant looking at the display surface 25, making it possible to view the display 20A from a wide range.

[0036] Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these. Various modifications based on the knowledge of those skilled in the art are possible as long as they do not deviate from the spirit of the claims. [Explanation of symbols]
