[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-349977 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if a window in the vehicle compartment is open when the flexible display is in use, the flexible display may be blown around by the wind entering the vehicle compartment.

[0005] Therefore, this specification discloses a retractable in-vehicle display device that can suppress shaking of the flexible display when the flexible display is in use. [Means for solving the problem]

[0006] This specification discloses a retractable in-vehicle display device. The device includes a flexible display, guide rails, a display-side engaging part, and a floor-side engaging part. The flexible display is disposed within the vehicle interior and extends in the vehicle width direction. The guide rails are disposed on the ceiling of the vehicle interior. The guide rails enable the flexible display to slide between a stored position where it is disposed on the ceiling and an deployed position where it is pulled out in front of the seat. The display-side engaging part is disposed at the lower end of the flexible display in the deployed position. The floor-side engaging part engages with the display-side engaging part from the floor side of the vehicle interior.

[0007] According to the above configuration, the lower end of the flexible display is engaged with the floor, thereby suppressing the swinging of the flexible display.

[0008] Furthermore, in the above configuration, the floor-side engagement component may include a pair of pressing pins. The pair of pressing pins are arranged on both ends of the floor side in the vehicle width direction. Each of the pair of pressing pins includes a head and a biasing component. The head is movable in the vehicle width direction. The biasing component biases the head inward in the vehicle width direction. The display-side engagement component includes a pair of guide pieces. The pair of guide pieces are arranged at the lower end of the flexible display and both ends in the vehicle width direction. Each of the pair of guide pieces includes an insertion groove that is open downward. When the flexible display is unfolded, the head of the pressing pin is inserted into the insertion groove. The head has a tapered shape that becomes narrower as it goes inward in the vehicle width direction. The insertion groove has a tapered shape with the groove width narrowing as it goes inward in the vehicle width direction.

[0009] According to the above configuration, the guide piece and the pressing pin are engaged with each other, thereby making it possible to position the flexible display in the longitudinal direction and the width direction of the vehicle.

[0010] In the above configuration, the head of the pressing pin may be elongated vertically, i.e., the pressing pin is longer in the up-down direction than in the front-rear direction.

[0011] According to the above configuration, it is possible to prevent the guide piece from rotating around the central axis of the pressing pin.

[0012] In the above configuration, the display-side engaging part may include a lock pin arranged at the lower end of the flexible display and at the center in the vehicle width direction. The floor-side engaging part may include a pin receiving mechanism at the center in the vehicle width direction on the floor side. The pin receiving mechanism has a hollow structure. The pin receiving mechanism has a receiving port that opens toward the ceiling. The lock pin is inserted into the pin receiving mechanism through the receiving port, and the lock pin is then caught on the inner wall surface of the pin receiving mechanism, thereby fixing the flexible display.

[0013] According to the above-described configuration, the lower end of the flexible screen is engaged with the floor side at the center portion in the vehicle width direction in addition to both ends in the vehicle width direction.

[0014] In the above configuration, the insertion grooves of the pair of guide pieces may be positioned below the lock pin. The pair of pressure pins may be positioned below the receiving opening of the pin receiving mechanism. In this case, the distance between the lower end of the lock pin and the lower end of the insertion groove is equal to the distance between the receiving opening and the pressure pin.

[0015] According to the above configuration, the lock pin is inserted into the receiving opening at the same time as the pressing pin is inserted into the lock pin insertion groove, thereby quickly fixing the flexible display. [Effects of the Invention]

[0016] The retractable in-vehicle display device disclosed in this specification can suppress shaking of the flexible display when the flexible display is in use. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following describes a retractable in-vehicle display device according to the present embodiment with reference to the drawings. The shapes, materials, quantities, and values ​​described below are examples for illustrative purposes only and can be changed as appropriate depending on the specifications of the retractable in-vehicle display device. Furthermore, the same reference numerals are used for equivalent elements in all drawings below.

[0019] In addition, in Figures 1 to 7, a Cartesian coordinate system consisting of the FR axis, LH axis, and UP axis is used to represent the position and direction of each component. The FR axis is the longitudinal axis of the vehicle, with the front of the vehicle being the positive direction. The LH axis is the transverse axis of the vehicle, with the left side of the vehicle being the positive direction. The UP axis is the vertical axis of the vehicle, with the upward direction being the positive direction.

[0020] <Vehicle interior structure> 1 and 2 show an example of the structure inside a vehicle interior 10. A retractable in-vehicle display device according to this embodiment is disposed inside the vehicle interior 10. As will be described later, the retractable in-vehicle display includes a flexible display 50, a pair of guide rails 56, 56, a pair of guide pieces 60, 60, a lock pin 70, a pair of holding pins 30, 30, and a pin receiving mechanism 40. The pair of guide pieces 60, 60 and the lock pin 70 are included in the display-side engaging parts. The pair of holding pins 30, 30 and the pin receiving mechanism 40 are included in the floor-side engaging parts.

[0021] 1 and 2, a door is provided on only one side of the vehicle interior 10. For example, as illustrated in FIGS. 1 and 2, no door is provided on the right side of the vehicle interior 10. On the left side of the vehicle interior 10, for example, a sliding door (not shown) is provided.

[0022] A pair of separate seats 14, 14 are arranged as front seats on a floor 12 of the vehicle interior 10. The separate seats 14, 14 are positioned so as to face rearward, for example.

[0023] A bench seat 16 is disposed as a rear seat on the floor 12. The bench seat 16 is positioned so as to face forward, for example. That is, the pair of separate seats 14, 14 and the bench seat 16 are disposed so as to face each other.

[0024] A handrail 20 is disposed on the floor 12 between the pair of separate seats 14, 14 and the bench seat 16. The handrail 20 is an aid for assisting passengers when getting on and off the vehicle. For example, passengers seated on the pair of separate seats 14, 14 and the bench seat 16 hold onto the handrail 20 and stand up from their seats when getting off the vehicle.

[0025] The handrail 20 is made of, for example, a metal pipe. The handrail 20 is formed by bending this pipe. The handrail 20 has a U-shape that is open at the bottom, and includes a pair of vertical posts 21, 21 and a crossbar 25. The pair of vertical posts 21, 21 are arranged at both ends of the floor 12 in the vehicle width direction. The crossbar 25 connects the upper ends of the pair of vertical posts 21, 21. The crossbar 25 extends along the vehicle width direction. A retractable table may be installed on the handrail 20. For example, this table can rotate between a horizontal position and a vertical position around the crossbar 25 as a rotation axis.

[0026] A floor-side engaging part is disposed on the handrail 20. The floor-side engaging part includes a pair of retaining pins 30, 30 and a pin receiving mechanism 40. A retaining pin 30 is disposed on each of the pair of vertical pillars 21, 21. As described above, the vertical pillars 21, 21 are disposed on both ends of the floor 12 in the vehicle width direction. Therefore, the retaining pins 30 disposed on the vertical pillars 21 are also disposed on both ends of the floor 12 in the vehicle width direction. The detailed structure of the retaining pins 30 will be described later.

[0027] A pin receiving mechanism 40 is disposed on the cross member 25. For example, the pin receiving mechanism 40 is provided in the center of the cross member 25 in the vehicle width direction. In other words, the pin receiving mechanism 40 is disposed in the center of the vehicle width direction on the floor 12 side. The detailed structure of the pin receiving mechanism 40 will be described later.

[0028] <Cabinet ceiling structure> 2 illustrates an example of the structure around the roof trim 18, which is a ceiling panel of the vehicle interior 10. The roof trim 18 has a flexible display 50 and guide rails 56 arranged thereon.

[0029] The flexible display 50 is disposed in the vehicle interior 10 and extends in the vehicle width direction. For example, the flexible display 50 extends across the entire width of the vehicle interior 10 in the vehicle width direction. The length of the flexible display 50 is the height from the cross member 25 of the handrail 20 to the roof trim 18 plus a predetermined margin. The length of the flexible display 50 refers to the dimension in the vehicle's fore-and-aft direction when in the stored position.

[0030] Here, the stored position refers to a state in which the entire surface of the flexible display 50 is located below the roof trim 18. In contrast, the unfolded position refers to a state in which the flexible display 50 is pulled out and its lower end is engaged with the cross bar 25. In the unfolded position, the flexible display 50 is pulled out in front of the bench seat 16.

[0031] The flexible display 50 has a substrate and light-emitting elements. The substrate is flexible and may be, for example, a plastic substrate. The light-emitting elements may be, for example, organic EL display elements or liquid crystal elements. The flexible display 50 also includes electrical wiring and signal wiring (not shown). These wirings are connected to, for example, an image display ECU (not shown) inside the vehicle.

[0032] The flexible display 50 may be double-sided. That is, two flexible displays 50 are attached back to back. This allows the image output from the flexible display 50 to be viewed from both the separate seat 14 and the bench seat 16.

[0033] A pair of sliders 52, 52 are attached to both ends of the flexible display 50 in the vehicle width direction. The sliders 52, 52 extend over the entire length of the flexible display 50. The sliders 52, 52 are flexible components. For example, the sliders 52, 52 are made of an elastic material such as rubber.

[0034] A pair of guide rails 56, 56 are provided on both ends of the flexible display 50 in the vehicle width direction. The guide rails 56, 56 are arranged on the roof trim 18, which is the ceiling of the vehicle interior 10. The guide rails 56, 56 extend in the front-to-rear direction of the vehicle. The guide rails 56, 56 have, for example, a J-shaped cross section with an opening on the inner side in the vehicle width direction.

[0035] The sliders 52 are inserted into the guide rails 56. The guide rails 56 regulate the movement direction of the sliders 52. That is, the sliders 52 move in the front-to-rear direction within the guide rails 56. The sliders 52 and the flexible display 50 that protrude from the guide rails 56 hang down due to gravity. In this way, the pair of guide rails 56 allows the flexible display 50 to slide between the stored position and the deployed position.

[0036] One end of a biasing member 58 is attached to the rear end 52A of the slider 52. The other end of the biasing member 58 is fixed to the rear end of the guide rail 56. The biasing member 58 is, for example, a spring. When the flexible display 50 is pulled out to the deployed position by the occupant, the biasing member 58 is extended. When the lock pin 70 is disengaged from the pin receiving mechanism 40, the elastic force of the biasing member 58 causes the flexible display 50 to return to the stored position.

[0037] Instead of using the biasing member 58, a motor (not shown) may move the flexible display 50.

[0038] A lower crosspiece 54 is attached to the lower end of the flexible display 50. The lower crosspiece 54 connects the lower ends of the sliders 52, 52 together. The lower crosspiece 54 extends in the vehicle width direction. The lower crosspiece 54 is made of a metal material such as aluminum, and has a predetermined rigidity. As illustrated in FIG. 5 , the lower crosspiece 54 has, for example, a rectangular cylindrical shape and a hollow structure.

[0039] As illustrated in FIG. 2 , a pair of guide pieces 60, 60 are provided at both ends of the lower rail 54 in the vehicle width direction. A lock pin 70 is also provided in the center of the lower rail 54 in the vehicle width direction. In other words, the pair of guide pieces 60, 60 are arranged at the lower end of the flexible display 50 and both ends in the vehicle width direction. The lock pin 70 is also arranged at the lower end of the flexible display 50 and in the center in the vehicle width direction. The pair of guide pieces 60, 60 and the lock pin 70 are collectively referred to as display-side engaging parts. In other words, the display-side engaging parts are arranged at the lower end of the flexible display 50 in the unfolded position. As will be described later, when the flexible display 50 is unfolded, the display-side engaging parts engage with the floor-side engaging parts.

[0040] <Display side engagement parts> The display-side engaging component includes a pair of guide pieces 60, 60 and a lock pin 70. Fig. 3 shows an enlarged perspective view of the guide piece 60. The guide piece 60 has a vertically elongated shape. The upper end of the guide piece 60 is connected to the lower rail 54.

[0041] The guide piece 60 includes a main body 62 and an insertion groove 64. The main body 62 is a plate portion extending in the vertical direction. The insertion groove 64 is provided at the lower end of the main body 62.

[0042] The insertion groove 64 is a U-shaped groove that is open downward. A side surface 66 of the insertion groove 64 is tapered. That is, as is clear from a comparison of the groove widths W1 and W2, the width of the insertion groove 64 narrows toward the inside in the vehicle width direction. As will be described later, when the flexible display 50 is unfolded, the head 32 of the retaining pin 30 is inserted into the insertion groove 64.

[0043] 4 illustrates an enlarged perspective view of the lock pin 70. The lock pin 70 includes a head 72, a rod 74, a stopper 76, and a disk 78.

[0044] The lock pin 70 is attached to the center of the lower crosspiece 54 in the vehicle width direction. For example, a through-hole (not shown) is drilled in the thickness direction in the bottom wall of the lower crosspiece 54, which has a rectangular cylindrical shape. A rod 74 is inserted into the through-hole. A stopper 76 is fixed to the upper end of the rod 74. This allows the lock pin 70 to rotate relative to the lower crosspiece 54, with the rod 74 as the rotation axis. Note that this rotation axis is parallel to the vertical axis (UP axis).

[0045] A head 72 is attached to the lower end of the rod 74. The head 72 is generally fan-shaped and includes an abutment surface 72A and a tapered surface 72B. The tapered surfaces 72B are formed at the lower end and both longitudinal ends of the head 72. The tapered surfaces 72B slope upward from the center of the head 72 toward the outside. As will be described later, when the head 72 is inserted into the receiving opening 42, the tapered surfaces 72B guide the head 72 in the vehicle width direction.

[0046] The abutment surface 72A is shaped to follow the cross-sectional shape of the crosspiece 25, which is the pin receiving mechanism 40. For example, the crosspiece 25 of the handrail 20 is a metal pipe, and its cross-sectional shape is circular. Therefore, the shape of the abutment surface 72A is an arc. As shown in FIG. 5, which will be described later, the abutment surface 72A abuts against the inner circumferential surface 44 (inner wall surface) of the crosspiece 25. This causes the lock pin 70 to engage with the pin receiving mechanism 40.

[0047] A disk 78 is provided in the center portion of the rod 74. The disk 78 is a circular disk for rotating the head 72. For example, when the flexible display 50 is deployed, the disk 78 is rotated by the passenger.

[0048] <Floor side engaging parts> As illustrated in Figure 2, a floor-side engaging part is disposed on the handrail 20. The floor-side engaging part includes a pair of retaining pins 30, 30 and a pin receiving mechanism 40. The floor-side engaging part engages with the display-side engaging part from the floor 12 side of the vehicle interior 10 (see Figure 1).

[0049] As will be described later, when the flexible display 50 is unfolded, the display-side engaging parts (guide piece 60, lock pin 70) engage with the floor-side engaging parts (holding pin 30, pin receiving mechanism 40). This engagement fixes the lower end of the flexible display 50 to the floor 12 side (see FIG. 1).

[0050] As illustrated in Fig. 3, the pressure pin 30 includes a head 32, a rod 34, a stopper 36, and an urging member 38. The pressure pin 30 is provided on the vertical pillar 21 of the handrail 20. As illustrated in Fig. 2, a pressure pin 30 is provided on each of the pair of vertical pillars 21. Therefore, the pair of pressure pins 30 are disposed on both ends of the floor 12 side in the vehicle width direction.

[0051] The vertical pillar 21 is cylindrical and has a slit 22 cut into its outer portion in the vehicle width direction. A rod 34 is inserted into this slit 22. The rod 34 is a bar-shaped part that extends in the vehicle width direction. The head 32 is connected to the outer end of the rod 34 in the vehicle width direction. A stopper 36 is connected to the inner end of the rod 34 in the vehicle width direction. The diameter of the stopper 36 is larger than the opening width of the slit 22.

[0052] A guide ring (not shown) may also be provided in the slit 22. The opening axis of the guide ring faces the vehicle width direction. A rod 34 is inserted into the guide ring. The guide ring restricts the movement direction of the rod 34 in the vehicle width direction. In conjunction with the rod 34, the head 32 can also move in the vehicle width direction.

[0053] The biasing member 38 is, for example, a spring. An outer end of the biasing member 38 in the vehicle width direction abuts against the end 22A of the slit 22. An inner end of the biasing member 38 in the vehicle width direction abuts against the stopper 36. With this configuration, when the head 32 is pulled outward in the vehicle width direction, the biasing member 38 is compressed. As a result, the head 32 is biased inward in the vehicle width direction.

[0054] The head 32 may be elongated. That is, the vertical dimension of the pressing pin is longer than the longitudinal dimension. As shown in Fig. 3, the head 32 has a rounded rectangular shape when viewed in the vehicle width direction.

[0055] As will be described later, when the flexible display 50 is unfolded, the press pin 30 is inserted into the insertion groove 64 of the guide piece 60. At this time, the head 32 fits into the insertion groove 64. Because the press pin 30 has a vertically elongated shape, rotation of the guide piece 60 around the central axis of the press pin 30 is suppressed.

[0056] The semicircle at the upper end of the head 32 has the same diameter as the semicircle at the upper end of the insertion groove 64, for example. The head 32 is also trapezoidal in a front view (viewed from the front rear axis). In other words, the head 32 has a tapered shape that becomes thinner as it goes inward in the vehicle width direction. This taper angle is equal to the taper angle of the insertion groove 64.

[0057] Note that manufacturing tolerances are set when manufacturing the head 32 and the insertion groove 64. Even if a difference occurs in the taper angles of the head 32 and the insertion groove 64, as long as the difference is within the manufacturing tolerance, the taper angles of the head 32 and the insertion groove 64 are considered to be equal.

[0058] 4 shows an enlarged perspective view of the pin receiving mechanism 40. In this example, the pin receiving mechanism 40 is formed in the crosspiece 25 of the handrail 20. That is, the pin receiving mechanism 40 has a hollow structure and further includes a receiving opening 42. The receiving opening 42 opens toward the ceiling of the vehicle compartment 10 (see FIG. 2).

[0059] In the example of Figure 4, the crosspiece 25 of the handrail 20 is cylindrical and hollow. A receiving opening 42 is drilled in the center of the crosspiece 25 in the vehicle width direction. In this way, the hollow structure of the crosspiece 25 is used to form the pin receiving mechanism 40. The slit width W4 of the receiving opening 42 exceeds the width W3 of the head 72 of the lock pin 70. Furthermore, the opening length L1 of the receiving opening 42 exceeds the overall length L2 of the head 72.

[0060] 6 illustrates the height positions of the display-side engaging part and the floor-side engaging part. In the floor-side engaging part, the pair of retaining pins 30, 30 are positioned below the receiving opening 42 of the pin receiving mechanism 40. In addition, in the display-side engaging part, the insertion grooves 64 provided in each of the pair of guide pieces 60, 60 are positioned below the lock pin 70.

[0061] Here, the distance H1 between the lower end of the lock pin 70 and the lower end of the insertion groove 64 is equal to the distance H2 between the receiving opening 42 and the pressing pin 30. With this structure, when the pressing pin 30 is inserted into the insertion groove 64, the head 72 of the lock pin 70 is inserted into the receiving opening 42 at the same time. In other words, the flexible display is quickly unfolded.

[0062] <Display development process> 2 to 4, the flexible display 50 in the stored position is pulled out by a passenger. This pulling out operation is performed by, for example, two passengers. For example, the passengers pull the flexible display 50 forward and downward while holding the lower rail 54.

[0063] Next, as shown in Figure 3, the head 32 of the retaining pin 30 is pulled out from the vertical pillar 21. In other words, the head 32 is pulled outward in the vehicle width direction. Then, the guide piece 60 is lowered. This causes the head 32 to be inserted into the insertion groove 64.

[0064] The head 32 is biased inward in the vehicle width direction by the elastic force of the biasing component 38. The insertion groove 64 is sandwiched between the head 32 and the vertical column 21. Referring to Figure 2, the pair of guide pieces 60, 60 engage with the pair of retaining pins 30, 30, thereby completing the positioning of the flexible display 50 in the vehicle front-rear direction and vehicle width direction.

[0065] In parallel with the process of inserting the insertion groove 64 of the guide piece 60 into the head 32, the head 72 of the lock pin 70 (see FIG. 4) is inserted into the receiving opening 42 of the pin receiving mechanism 40. Thereafter, as illustrated in FIG. 5, the occupant turns the disk 78, causing the head 72 to rotate. This rotation causes the abutment surface 72A of the head 72 to fit into the inner circumferential surface 44 of the crossbar 25. As a result, the head 72 of the lock pin 70 becomes caught on the inner wall surface of the pin receiving mechanism 40, i.e., the inner circumferential surface 44 of the crossbar 25. This catch secures the flexible display 50 to the floor 12 side (see FIG. 1).

[0066] Here, at both ends of the flexible display 50 in the vehicle width direction, a pair of guide pieces 60, 60 engage with a pair of pressing pins 30, 30. Therefore, even if outside air blows into the vehicle interior 10, shaking (flapping) of the flexible display 50 is suppressed.

[0067] <Another example of a retractable in-vehicle display device> 1 to 6, the floor-side engaging parts are mounted on the handrail 20. However, the retractable vehicle-mounted display device disclosed in this specification is not limited to this configuration.

[0068] For example, Fig. 7 illustrates a configuration in which the handrail 20 is removed from the vehicle compartment 10. In this case, floor-side engaging parts are arranged on the floor 12 of the vehicle compartment 10. That is, a pair of storage cases 120, 120 and a receiving case 140 are embedded in the floor 12.

[0069] A pair of storage cases 120, 120 are arranged on both ends of the floor 12 in the vehicle width direction. The retaining pin 30 is stored inside the storage case 120. The top of the storage case 120 is covered with a lid 121. When the flexible display 50 is unfolded, the lid 121 is opened.

[0070] Furthermore, a pin receiving mechanism 40 is disposed in the center of the floor 12 in the vehicle width direction. The pin receiving mechanism 40 includes a receiving case 140. The receiving case 140 has a hollow structure, and is formed with a receiving opening 42 that opens toward the ceiling. When the flexible display 50 is unfolded, a lock pin 70 (see FIG. 2) engages with the receiving case 140. [Explanation of symbols]
