  • the lid 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 lid 19 is rotated upward, the torsion spring 193 is compressed between the lower plate 192 and the top plate 16, biasing the lower plate 192 downward.
  • 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. Also, the elastic member is not limited to a spring, but may be other materials, such as rubber.
  • the lower plate 192 When the cover 19 is rotated downward, the lower plate 192 is formed to fit along the lower ends of the side plates 11 and 12 of the base 10.
  • a standing plate 190 is provided on the front edge of the lower plate 192 facing upward, and a passive part 194 is extended forward from the upper edge of the standing plate 190.
  • 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 parts (shaft holes) 21, 22 on the left and right sides, respectively.
  • the display 20 has a cover plate 23 that covers the gap between the side plate 11 and the side of the display 20, and a cover plate 24 that covers the gap between the side plate 12 and the side of the display 20, both of which are provided along the sides of the display 20.
  • the display 20 is rotatably held relative to the base unit 10 by inserting the shafts 31, 32, which are attached to the side plates 11, 12 of the base unit 10 in the horizontal direction (X-axis direction), into the bearings (shaft holes) 21, 22. That is, in this embodiment, the bearings 21, 22 and the shafts 31, 32 constitute the rotation mechanism 30. Note that in this embodiment, the shafts 31, 32 are provided on the base unit 10 side and the bearings (shaft holes) 21, 22 are provided on the display 20 side, but the bearings may be provided on the base unit 10 side and the shafts on the display 20 side. Also, the rotation mechanism is not limited to shafts and shaft holes, and may have other configurations as long as it can hold the display 20 rotatably.
  • 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 Figures 5 and 6.
  • This state in which the display 20 is in the first position is also referred to as the state in which the display 20 is closed.
  • the elastic force of the torsion spring 193 causes the lid part 19 to be lowered to a position where the passive part 194 abuts against the upper surface of the display 20.
  • this position is also referred to as the first position.
  • 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 called the state in which the display 20 is open.
  • the display 20 rotates around 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 portion 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 plate 43 and the roof lining 41 in the ceiling portion of the vehicle.
  • the user manually pulls down the bottom end portion 201 of the display 20 or pushes up the top end portion 202.
  • This causes the display surface 25 of the display 20 to face the viewing position (eye point) where the rear passengers are sitting, and the display 20 takes the second position. That is, the display device 1 is unfolded and in use.
  • the top end of the display 20 pushes up the passive part 194 of the lid part 19, causing the lid part 19 to rotate around the rotation axis 191 and move to the second position.
  • the lid part 19, which is positioned in the first position when the display 20 is closed, covers the passenger compartment side of the in-ceiling space 44 and prevents the in-ceiling space 44 from being seen by the rear passengers, thereby enhancing the aesthetic appearance when the display 20 is closed.
  • the lid 19 moves to a second position that is out of the field of view when viewing the display surface 25 from the viewing position, for example, to a predetermined area 205 on the display surface side of the display, so that the lid 19 does not hide the display surface of the display 20.
  • the deployment of the display 20 does not necessarily have to be manual, but may be accomplished by a drive unit such as a motor or actuator, which moves the display 20 from the first position to the second position.
  • a drive unit such as a motor or actuator, which moves the display 20 from the first position to the second position.
  • the drive unit may drive the rotation mechanism 30 to move the display 20 from the first position to the second position.
  • 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 vertical direction of the display 20), so the portion located above this rotation axis is moved 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 vertical 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 ceiling space 44 in the second position.
  • the upper end portion 202 that is accommodated in the ceiling space 44 in the second position may be 1/2 to 1/4 of the display 20 in the vertical direction.
  • the upper end portion 202 is disposed in the ceiling space 44, so that the portion that protrudes below the roof lining 41 is reduced.
  • FIG. 7 shows an example of a comparative example in which a display device 90 having a rotation axis 9X at the top end of a display 91 is mounted on the ceiling of a vehicle 80
  • FIG. 8 shows an example in which a display device 1 of this embodiment is mounted on the ceiling of a vehicle 80.
  • a display device 90 of the comparative example when the display 91 is rotated from a closed state to an open state and the display surface 92 is directed toward the eye point 81, most of the display 91 is located within the field of view 84 of the occupant (driver) sitting in the driver's seat when checking the rear of the vehicle through the inner mirror 82. As a result, the field of view 84 is blocked in the range 85 where the display 91 is located.
  • the display device 1 of this embodiment when the display 20 is opened, the upper end portion of the display 20 is contained 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 vision 84.
  • the field of vision 84 is blocked in the range 86 where the lower end portion 201 of the display 20 is located. In this way, with the display device 1 of this embodiment, the range 86 that blocks the occupant's field of vision 84 can be kept smaller than the range 85 in the comparative example.

  • Fig. 14 is a perspective view of the display device 1A according to Fig. 13.
  • This embodiment differs from the first embodiment described above in that the lid portion 19A is connected to the display 20A, and the lid portion 19A moves from a first position to a second position as the display 20A rotates. Since the other configurations are the same, the same elements are given the same reference numerals and will not be described again.
