Therefore, each support arm expands and contracts with precision as the display unit moves in and out, and the display unit is effectively supported by the lid part having the support arms.

[0016] Also, claims 5 The vehicle display device according to the present invention includes a display device for a vehicle, ... 4 In the vehicle display device according to any one of the above, the support mechanism includes a side edge support portion that supports a side edge portion of the display portion.

[0017] Claim 5 According to the invention described in the above, the support mechanism includes side edge support parts that support the side edges of the display unit, thereby ensuring rigidity of the display unit in the torsional direction compared to a case where the support mechanism does not include side edge support parts that support the side edges of the display unit.

[0018] Also, claims 6 The vehicle display device according to the present invention includes a display device for a vehicle, ... 5In the display device for a vehicle according to any one of the above, the display unit is housed on the rear side of the ceiling and substantially parallel to the ceiling.

[0019] Claim 6 According to the invention described in the above, the display unit is stored on the underside of the ceiling, substantially parallel to the ceiling.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. For convenience of explanation, the arrow UP shown in each drawing indicates the upward direction of the vehicle body, the arrow FR indicates the forward direction of the vehicle body, and the arrow LH indicates the leftward direction of the vehicle body. In the following description, when the directions of up / down, front / rear, and left / right are mentioned unless otherwise specified, they refer to up / down in the up / down direction of the vehicle body, front / rear in the front / rear direction of the vehicle body, and left / right in the left / right direction of the vehicle body (vehicle width direction).

[0023] 1, a vehicle 10 equipped with a vehicle display device 40 according to this embodiment includes a vehicle body 12 that constitutes a main portion of a vehicle interior 14. A floor portion 16 is disposed below the vehicle body 12, and a roof portion 18 is disposed above the vehicle body 12. A seat 20 for an occupant P to sit on is disposed on the floor portion 16.

[0024] The seat 20 is configured to include a seat cushion 22 that supports the buttocks and thighs of the occupant P, a seat back 24 that supports the back of the occupant P, and a headrest 26 that supports the head of the occupant P. The lower end of the seat back 24 is rotatably supported on the rear end of the seat cushion 22, and the tilt angle thereof is adjustable.

[0025] A front windshield glass 28 is disposed in front of the seat 20, i.e., in front of the passenger compartment 14. The front windshield glass 28 is made of a transparent glass plate and extends downward and forward from the front peripheral edge of the roof portion 18 in a side view seen in the vehicle width direction.

[0026] The roof portion 18 is equipped with a roof panel 30 that forms part of the design surface of the vehicle body 12. The roof panel 30 is covered from below by a roof trim 32 that serves as an interior member. The roof trim 32 forms the ceiling of the vehicle interior 14 and is mainly composed of a ceiling portion 32A that forms the ceiling of the vehicle interior 14 and a front wall portion 32B that extends upward from the front peripheral edge of the ceiling portion 32A.

[0027] 2, the roof panel 30 is reinforced by a plurality of roof reinforcements 34 arranged at intervals in the front-to-rear direction. The roof reinforcement 34 is formed with a generally hat-shaped cross section and extends in the vehicle width direction, and in a cross-sectional view seen from the vehicle width direction, front and rear flange portions 34A are joined to the roof panel 30, thereby forming a closed cross-sectional shape together with the roof panel 30.

[0028] The roof reinforcement 34F located at the forefront is disposed along the front peripheral edge of the roof panel 30. Specifically, a front flange portion 34A of the roof reinforcement 34F is overlapped from below onto the front end portion of the roof panel 30, and an upper end portion of the front wall portion 32B is overlapped from below onto and joined to the flange portion 34A. The upper end portion of the front windshield glass 28 is overlapped and joined to the upper side of the front end portion of the roof panel 30.

[0029] A display 42 serving as a display unit constituting the vehicle display device 40 can be housed in the back side of the ceiling portion 32A of the roof trim 32, i.e., in the space S between the roof panel 30 and the ceiling portion 32A of the roof trim 32. The display 42 is a rectangular film equipped with an organic electroluminescence element, and has a display surface 42A (see FIGS. 7 and 9) on one side (the lower surface) that can display information to the occupant P (see FIG. 1).

[0030] The display 42 is electrically connected via wiring (not shown) to a control device (not shown) that performs various controls on the vehicle display device 40, and is driven by signals output from the control device to display various images and the like on the display surface 42A. The display 42 is supported on the roof portion 18 (roof panel 30) by a display support portion 60, and is configured to protrude from the ceiling portion 32A into the vehicle interior 14 or be stored on the back side of the ceiling portion 32A by a display drive portion 50.

[0031] Specifically, the display drive unit 50 includes a pair of pinions 52 supported on the roof reinforcement 34F via a pair of mounts 36, a pair of racks 44 (described later) that mesh with each pinion 52 from below, a motor 56 arranged coaxially with one of the pinions 52, and a pair of roller guides 58 that support the pair of racks 44 from below.

[0032] The racks 44 are made of a flexible material and are provided on both ends of the display 42 in the vehicle width direction, i.e., on the other surface (back surface) of the end (hereinafter referred to as "side edge") 42B that is outer in the vehicle width direction than the display surface 42A, along the entry / exit direction of the display 42. The side edge 42B that is outer in the vehicle width direction than the rack 44 is supported by a side edge support portion 46 that serves as a support mechanism configured to be slidable as the display 42 enters and exits from the ceiling portion 32A.

[0033] 2, when the display 42 is in the stored state, the side edge support portion 46 is disposed below the roller guide 58 (downstream in the direction of protrusion from the ceiling portion 32A). The side edge support portion 46 is made of resin, and as shown in FIG. 3, is composed of a plurality of slide members 47 formed with a generally U-shaped cross section.

[0034] The innermost slide member 47A is fixed to the lower end of a side edge portion 42B of the display 42 (directly above a lower edge reinforcing portion 43, which will be described later), and although not shown in detail, the outermost slide members 47B are each fixed to the mount 36. The slide members 47 are formed in a shape that overlaps (becomes larger) sequentially outward from the innermost slide member 47A to the outermost slide member 47B.

[0035] Furthermore, except for the outermost slide member 47B, the upper end of each slide member 47 is formed with a protruding portion (not shown) that engages with the lower end of the overlapping slide member 47. The inner end of each slide member 47 in the vehicle width direction is formed with a rail portion (not shown) that protrudes inward in the thickness direction of the display 42. Each rail portion is engaged with the inner end of the overlapping slide member 47 in the vehicle width direction, and is configured to be slidable along the inner end of the vehicle width direction.

[0036] With this configuration, each slide member 47 is slidable while covering the side edge portion 42B of the display 42 (see FIGS. 7 and 9). When the display 42 is in the stored state, the side edge support portion 46 is in the most contracted state in which the slide members 47 are overlapped with each other.

[0037] 2, the pair of pinions 52 are fixed to a rotary shaft 54 extending in the vehicle width direction and mesh with each rack 44. An output shaft (not shown) of a motor 56 is coaxially and integrally connected to the rotary shaft 54 on the outer side of one of the pinions 52 in the vehicle width direction, and the pinions 52 can rotate synchronously in both forward and reverse directions when the motor 56 is driven based on a control signal from a control device. This allows the display 42 to be inserted and removed from the ceiling portion 32A.

[0038] One end of the rotating shaft 54 on the side of one pinion 52 is supported by the mount 36 on one side via a bearing (not shown), and the other end of the rotating shaft 54 on the side of the other pinion 52 is also supported by the mount 36 on the other side via a bearing (not shown). Each mount 36 is fixed to a weld nut 38 provided on the roof reinforcement 34F with a fastening member (not shown).

[0039] The motor 56 is supported by one of the mounts 36, and although not shown in detail, each mount 36 also rotatably supports a roller guide 58. The roller guide 58 supports the lower surface of the rack 44 provided on the side edge 42B of the display 42 from below. The display 42 is guided by the rotation of the pinion 52 and the roller guide 58, and is sent out into the vehicle interior 14 (toward the front and lower side).

[0040] The display support portion 60 is configured to be able to support the upstream side of the protruding direction of the display 42, and is configured to include a pair of guide rails 62 and a pair of rail mounts 64. Each guide rail 62 extends along the front-to-rear direction (entrance / exit direction) in correspondence with the side edge portion 42B of the display 42, rearward of the roller guide 58, and is formed in a substantially "U" shape that opens inward in the vehicle width direction when viewed from the front-to-rear direction.

[0041] The side edge 42B of the display 42 including the rack 44 can be inserted into each guide rail 62, and each guide rail 62 can guide the display 42 along the insertion / removal direction (front-to-rear direction). Each guide rail 62 is attached to the roof reinforcement 34 rearward of the roof reinforcement 34F via a rail mount 64. In other words, each rail mount 64 is fixed to a weld nut 38 provided on the roof reinforcement 34 with a fastening member (not shown).

[0042] 2, a recess 33 that is bent upward and recessed is formed at a predetermined position in the vehicle width direction at the boundary between the ceiling portion 32A and the front wall portion 32B of the roof trim 32. A slit portion T that extends in the vehicle width direction is formed behind the recess 33, and the display 42 can pass through this slit portion T and protrude into the vehicle interior 14 from the back side of the ceiling portion 32A.

[0043] A flat lid 70 having a longitudinal direction in the vehicle width direction is provided at the bottom surface of the recess 33 so as to be able to turn at its front end so as to close the slit T from below. As also shown in Fig. 10, a pair of brackets 66 are integrally provided to protrude from both ends of the bottom surface of the recess 33 in the vehicle width direction, and each bracket 66 is formed with a through-hole (not shown) that penetrates in the vehicle width direction.

[0044] Meanwhile, a cylindrical portion 71 is integrally formed at the front end of the lid portion 70 and is disposed between the brackets 66. The inner diameter of the cylindrical portion 71 is larger than the inner diameter of the through-holes of the brackets 66. Therefore, by disposing each cylindrical portion 71 between the brackets 66 and inserting a columnar pin 67 or the like having an outer diameter that can be press-fitted into the through-hole of the bracket 66 into the through-hole of the bracket 66 and the through-hole of the cylindrical portion 71, the lid portion 70 is configured to be rotatable with respect to the recess 33.

[0045] The lid portion 70 is held in a closed state with its thickness direction in the vertical direction when the display 42 is not in use (when the display 42 is stored) by the biasing force of the torsion spring 68 fitted to the outer peripheral surface of the cylindrical portion 71, and is configured to open and close as the display 42 is inserted or removed.

[0046] In other words, when the lid portion 70 is pushed from above by the display 42 attempting to protrude downward and forward from the slit portion T, the rear end portion thereof rotates downward around the pin 67 against the force of the torsion spring 68, and is configured to enter an open state.

[0047] 2, a pair of support arms 72 serving as a support mechanism are provided on both ends in the vehicle width direction on the rear surface (upper surface when closed) of the lid portion 70. As shown in FIGS. 4, 5, and 10, each support arm 72 is made of metal and includes a cylindrical small diameter rod 78, a cylindrical large diameter rod 74, and a cylindrical medium diameter rod 76 having a diameter larger than that of the small diameter rod 78 and smaller than that of the large diameter rod 74.

[0048] As shown in Figures 4 and 5, each support arm 72 is provided with a compression coil spring (hereinafter simply referred to as "coil spring") 75 between the large diameter rod 74 and the medium diameter rod 76 as a biasing member that constantly biases the medium diameter rod 76 toward the inside of the large diameter rod 74 (constantly biases the support arm 72 in a direction that shortens the overall length of the support arm 72).

[0049] That is, one end 75A of the coil spring 75 abuts against a flange portion 74F formed to protrude radially inward from one end 74A of the large diameter rod 74, and the other end 75B of the coil spring 75 abuts against a flange portion 76Fb formed to protrude radially outward from the other end 76B of the medium diameter rod 76. This constantly biases the flange portions 74F and 76Fb in directions separating them from each other.

[0050] Similarly, each support arm 72 has a compression coil spring (hereinafter simply referred to as "coil spring") 77 between the medium diameter rod 76 and the small diameter rod 78 as a biasing member that constantly biases the small diameter rod 78 toward the inside of the medium diameter rod 76 (constantly biases the small diameter rod 78 in the direction of shortening the overall length of the support arm 72).

[0051] That is, one end 77A of the coil spring 77 abuts against a flange portion 76Fa formed to protrude radially inward from one end 76A of the medium diameter rod 76, and the other end 77B of the coil spring 77 abuts against a flange portion 78F formed to protrude radially outward from the other end 78B of the small diameter rod 78. This constantly biases the flange portions 76Fa and 78F in directions separating them from each other.

[0052] A locking protrusion 80 is integrally formed at the tip (one end) of the small diameter rod 78 as a locking portion that is locked with an engagement roller 48, which will be described later. As shown in Figures 4 and 5, the locking protrusion 80 is formed in a substantially cylindrical shape, and is bent in a substantially "L" shape in a cross section cut along its axial direction, and is configured so that when the display 42 is protruded from the ceiling portion 32A, the engagement roller 48 engages with it from above (so that the engagement roller 48 gets caught on it) (see Figure 8).

[0053] 2, 8, and 10, a resin lower edge reinforcement 43 is provided along the entire length of the lower edge of display 42 to reinforce the lower edge. Due to the weight of lower edge reinforcement 43, the front side of display 42 in front of roller guide 58 hangs downward and forward in the stored state (see FIG. 2). A pair of engaging rollers 48 are rotatably provided on both ends in the longitudinal direction (vehicle width direction) of lower edge reinforcement 43 on the back side opposite display surface 42A.

[0054] 8 and 10, a pair of brackets 41 are integrally provided to protrude from both longitudinal ends (directly below the slide member 47A) on the back surface of the lower edge reinforcing portion 43, and a through hole (not shown) is formed in each bracket 41. A through hole (not shown) is also formed in the axial center of the engaging roller 48, and the inner diameter of the through hole is larger than the inner diameter of the through hole in the bracket 41.

[0055] Therefore, the engaging rollers 48 are arranged between the brackets 41, and the engaging rollers 48 are configured to be rotatable by inserting cylindrical pins 82 or the like having an outer diameter that can be press-fitted into the through holes of the brackets 41 through the through holes of the brackets 41 and the engaging rollers 48. The axial center portion of the engaging rollers 48 is recessed in a substantially arc-shaped cross section over the circumferential direction, and the locking protrusions 80 are adapted to engage with the recessed portions 48A that are recessed in a substantially arc-shaped shape (see FIGS. 8 and 10).

[0056] Next, the operation of the vehicle display device 40 according to this embodiment configured as described above will be described.

[0057] 2, when the display 42 is not in use, the display 42 remains housed behind the ceiling portion 32A of the roof trim 32. At this time, most of the side edge 42B of the display 42 is held by the guide rails 62. The lower edge of the display 42 is reinforced by a lower edge reinforcing portion 43, and the portion of the display 42 in front of the roller guide 58 hangs downward and forward due to the weight of the lower edge reinforcing portion 43.

[0058] The side edge support parts 46 are arranged in a state where they are overlapped with each other so that the slide members 47 are at their shortest length (in their shortest state) at the hanging portion of the display 42. The slit part T is closed by the lid part 70, and in this state, the engagement roller 48 is located above the locking protrusion 80 and does not engage with (contact with) the locking protrusion 80.

[0059] 6 and 7, when a portion of the display surface 42A of the display 42 (for example, approximately the half on the downstream side in the protruding direction) is to be used, the pinion 52 is rotated a predetermined amount in the clockwise direction in FIG. 6 under the control of the control device, and the display 42 is sent forward downward and forward. At this time, as the display 42 moves downward and forward, the engagement roller 48 engages with the locking protrusion 80 of the support arm 72 from above. In other words, the locking protrusion 80 is relatively locked (hooked) by the engagement roller 48.

[0060] Then, in this state, the display 42 is sent further forward and downward, causing the rear end portion of the lid portion 70 to rotate downward about the pin 67 against the biasing force of the torsion spring 68, opening the slit portion T and causing the display 42 to protrude into the vehicle compartment 14. In other words, the display 42 protrudes into the vehicle compartment 14 with the upstream side of its side edge portion 42B in the protruding direction held by the guide rail 62 and its back side (front side) supported by the lid portion 70 via the pair of support arms 72.

[0061] At this time, the innermost slide member 47A constituting the side edge support portion 46 is pulled as the display 42 moves downward and forward, causing each slide member 47 to slide in the direction of extending relative to the other. As a result, the downstream side of the protruding direction of the side edge portion 42B of the display 42 is also supported by the side edge support portion 46 (each slide member 47).

[0062] Therefore, even if the display 42 is configured as a flexible film, its rigidity is ensured. In other words, even if the display 42 is in the form of a flexible film, it is possible to suppress the phenomenon in which the image displayed on the display 42 becomes difficult for the occupant P to view due to vibrations applied to the vehicle 10 while the vehicle 10 is traveling, for example, and thus to improve the visibility.

[0063] 8, 9, and 10, when the entire display surface 42A of the display 42 is to be used, the pinion 52 is further rotated a predetermined amount in the clockwise direction in Fig. 8 under the control of the control device, and the display 42 is sent forward downward and forward. Then, as the display 42 moves downward and forward, the engagement rollers 48 press the engagement protrusions 80 of the support arms 72 downward and forward while remaining engaged with them from above.

[0064] When each locking projection 80 is pressed downward and forward, each support arm 72 extends against the biasing force of the coil spring 75 and the coil spring 77. In other words, the cover 70 continues to support the display 42 from its rear side via the pair of support arms 72.

[0065] At this time, the innermost slide member 47A constituting the side edge support portion 46 is further pulled as the display 42 moves downward and forward, causing each slide member 47 to slide in a direction in which it extends relative to the others. In other words, the side edge support portion 46 reaches its maximum extension state, where it has the longest length. Therefore, the side edge 42B of the display 42 also remains supported by the side edge support portion 46 (each slide member 47).

[0066] In this way, the rigidity of the flexible film-like display 42 is ensured even when the entire display surface 42A of the display 42 protrudes into the vehicle interior 14. Moreover, as described above, the display 42 is configured to be supported from the rear side by the lid portion 70 via the pair of support arms 72, which improves the vibration resistance of the display 42 in the thickness direction when the vehicle 10 is traveling, etc.

[0067] Furthermore, since the engagement roller 48 provided on the lower edge reinforcing portion 43 is configured to engage with the locking protrusion 80 provided on the support arm 72 (the locking protrusion 80 is locked by the engagement roller 48), the support arm 72 can expand and contract with precision as the display 42 moves in and out. Therefore, the display 42 can be effectively supported by the lid portion 70.

[0068] Furthermore, when display 42 enters or leaves ceiling 32A, side edge 42B thereof is supported by side edge support portion 46 (plurality of sliding members 47 that slide). Therefore, rigidity against torsional bending of display 42 can be ensured compared to a case where side edge support portion 46 is not provided on side edge 42B of display 42.

[0069] 8, even when the entire display surface 42A of the display 42 protrudes into the vehicle interior 14, a portion of the side edge 42B remains held by the guide rail 62. Therefore, compared to a configuration in which the side edge 42B of the display 42 comes off the guide rail 62 when the entire display surface 42A of the display 42 protrudes into the vehicle interior 14, there is no need to re-engage the side edge 42B of the display 42 with the guide rail 62 when storing the display 42. Therefore, the display 42 can be stored smoothly.

[0070] That is, when display 42 is to be stored, pinion 52 is rotated counterclockwise in Figures 6 and 8 (the opposite direction to the above) under the control of the control device. Then, display 42, which has been protruding into passenger compartment 14, moves rearward and upward, and at that time, each support arm 72 is constantly biased in a direction to be shortened by coil spring 75 and coil spring 77, so it automatically shortens as display 42 moves rearward and upward.

[0071] That is, the support arms 72 are automatically stored in association with the storing operation of the display 42. Therefore, even when the display 42 is stored, the lid 70 can maintain a state in which it supports the display 42 from the rear side via the pair of support arms 72.

[0072] Furthermore, as the display 42 is stored, the slide members 47 constituting the side edge support parts 46 also slide in the direction of sequentially shortening relative to one another. When the display 42 is stored to a position where the lid part 70 closes the slit part T due to the biasing force of the torsion spring 68 (until the side edge support parts 46 are in the most shortened state), the engagement rollers 48 disengage from the locking protrusions 80, resulting in the state shown in FIG. 2.

[0073] Therefore, compared to a configuration in which the engagement roller 48 does not come off the locking projection 80, it is possible to reduce or prevent restrictions on the shapes of the lid portion 70 and the display 42. In other words, a certain degree of freedom can be ensured in the shapes of the lid portion 70 and the display 42.

[0074] Furthermore, display 42 is stored behind ceiling portion 32A and substantially parallel to ceiling portion 32A, except for the portion forward of roller guide 58 (the portion hanging down toward the front). Therefore, display 42 can be stored without widening the vertical gap of space S behind ceiling portion 32A, compared to when display 42 is not stored behind ceiling portion 32A and substantially parallel to ceiling portion 32A.

[0075] Although the vehicle display device 40 according to the present embodiment has been described above with reference to the drawings, the vehicle display device 40 according to the present embodiment is not limited to the one shown in the drawings, and the design can be appropriately modified within the scope of the gist of the present invention. For example, the support mechanism is not limited to the one shown in the drawings.

[0076] That is, the side edge support portions 46 are not limited to the configuration shown in the figure. The side edge support portions 46 may be made of, for example, hard rubber, and in that case, the side edge support portions 46 are flexible and deformable together with the display 42, and therefore can be stored further rearward than the roller guides 58.

[0077] Furthermore, the support arm 72 is not limited to the configuration shown in the figure, and the configuration for constantly biasing the support arm 72 in the direction of shortening is also not limited to the configuration shown in the figure. Furthermore, the locked portion is not limited to the engagement roller 48, and the locking portion is not limited to the locking protrusion 80. It is only necessary that the locked portion of the lower edge reinforcement portion 43 is configured so that the locking portion of the support arm 72 of the lid portion 70 can be locked as the display 42 moves in the protruding direction.
