It is rotatably connected via a shaft 37b.

  As shown in FIG. 1, a motor 41 and a gear box 45 are fixed to the drive mechanism 30 on the outer surface 2 b facing the back of the support base 2. As shown in FIGS. 2 and 3, a gear 43 rotated by the motor 41 and a clutch gear 44 rotated by the gear 43 are rotatably supported in the gear box 45. The clutch gear 44 is provided with a pinion gear (not shown) extending in the Y1 direction. In the drive mechanism 30, a fan gear 46 is provided on the inner surface facing the front (Y1 direction) of the support base 2. A support hole 46 a is formed in the sector gear 46, and the support hole 46 a is rotatably supported by a support shaft fixed to the inner surface of the support base 2. The tooth portion 46 b of the sector gear 46 meshes with the pinion gear that rotates together with the clutch gear 44. A driving arm 47 is fixed to the sector gear 46, and a driving link 48 is rotatably supported by a connecting shaft 47 a at the tip of the driving arm 47. As shown in FIG. 4, a drive action shaft 49 extending rearward (Y2 direction) is fixed to the lower portion of the slider 31, and the lower end portion of the drive link 48 is rotatably connected to the drive action shaft 49.

  When the power of the motor 41 is decelerated and transmitted from the pinion gear to the fan gear 46, and the fan gear 46 rotates, the turning force of the drive arm 47 acts on the drive action shaft 49 via the drive link 48, and the slider 31 moves. Guided by the straight guide 11 and moved up and down. The point of action where the moving force by the power of the motor acts on the slider 31 is the center of the drive action shaft 49. The action point and the center line of the straight guide portion 11 are arranged side by side in the front-rear direction (Y1-Y2 direction), and the action point and the center line of the straight guide portion 11 are located in the same YZ plane. Yes.

Next, the operation of the guide driving device 10 used as the display device 1 will be described.
In FIG. 1 and FIG. 2, the sector gear 46 is rotated clockwise, and the slider 31 is lowered along the linear guide portion 11. Since the first moving part 16 provided in the moving body 3 is sandwiched between the upper bearing piece 31a and the lower bearing piece 31b of the slider 31, the first moving part 16 is also at its highest when the slider 31 is lowered. It is moved to the lower end. The second moving unit 17 is also lowered by the transmission links 36 of the transmission unit 35 provided on both sides of the slider 31. Therefore, as shown in FIGS. 5A and 7A, the movable body 3 is in an initial posture moved downward (Z2 direction).

  The moving body 3 in the initial posture is a posture lowered along the surface of the instrument panel or the dashboard in the vehicle interior, or the moving body 3 in the initial posture is in a state of being lowered and stored inside the dashboard. .

  When an operation unit provided on the upper part of the moving body 3 is operated, or an operation unit provided on an instrument panel or the like is operated and an operation command for raising the moving body 3 is issued from a control unit (not shown), The motor 41 of the drive mechanism 30 is started and the sector gear 46 is driven counterclockwise. The rotational force of the drive arm 47 that rotates together with the fan gear 46 acts on the drive action shaft 49 located at the left and right center of the slider 31 from the drive link 48, and the slider 31 is lifted. As shown in FIGS. 5A and 5B, the sliding bearing member 32 is held by the upper bearing piece 31 a and the lower bearing piece 31 b of the slider 31, and the sliding bearing member 32 is inserted into the linear guide portion 11. Therefore, the slider 31 is guided by the linear guide 11 and moved upward along a linear locus. Since the moving force acts upward on the first moving portion 16 sandwiched between the upper bearing piece 31a and the lower bearing piece 31b of the slider 31, the moving body 3 is moved upward together with the slider 31. It is done. At this time, as shown in FIGS. 5A and 5B, since the linear guide portion 11 is sandwiched inside the groove 16a of the first moving portion 16, the first moving portion 16 and the moving body 3 are It moves upward while being restrained without moving in the left-right direction.

  The upward moving force of the slider 31 is transmitted from the connecting pieces 31 c on both the left and right sides of the slider 31 to the second moving part 17 via the transmission link 36, and the second moving part 17 is guided to the bending guide part 12. Lifted upward. As shown in FIGS. 7A and 7B, the holding sliding portion 18 provided in the second moving portion 17 holds the rail portion 14 that is the bending portion of the bending guide portion 12, and the second moving portion 17. The rail portion 14 is sandwiched between a pair of sandwiching rollers 21 provided on the rail. Therefore, the second moving unit 17 moves upward along the curved locus of the rail unit 14 without causing backlash. The moving body 3 also moves upward along the curved locus following the rail portion 14. When the moving body 3 moves upward, as shown in FIGS. 5A and 5B, the distance in the front-rear direction (Y1-Y2 direction) changes between the moving body 3 and the linear guide portion 11. Since the linear guide portion 11 is located inside the groove 16a of the first moving portion 16, it is possible to absorb a change in relative distance.

  As shown in FIG. 3 and FIG. 7B, when the moving body 3 is lifted and the movement is completed, the front surface 3b facing the Y1 direction of the moving body 3 faces obliquely upward toward the vehicle interior, and the front surface 3b The display screen provided in is obliquely upward.

  In the display device 1 of the first embodiment, the moving body 3 moves upward along a curved locus in which the projecting side is directed forward (in the Y1 direction) by the guide driving device 10 to reach a movement completion posture. When moving downward, it moves along a curved locus. Due to the movement along the curved locus, the moving body 3 is simultaneously moved in the vertical direction and tilted. Therefore, the movement of the moving body 3 is smooth, and the quality of the moving operation of the moving body 3 can be improved.

  In the guide drive device 10, the moving body 3 moves along a curved locus, but the slider 31 is guided by the linear guide portion 11 and moves linearly, so that the drive mechanism 30 that transmits the power of the motor 41 to the slider 31 is complicated. It is possible to smoothly move the slider 31 along the linear guide portion 11 without being changed.

  The moving body 3 has a first moving portion 16 at the left and right central portions. As shown in FIG. 4, the first moving portion 16 is spaced apart in the vertical direction (Z1-Z2 direction). A groove 16a or a long hole is formed, or a groove 16a or a long hole having a height dimension in the vertical direction (Z1-Z2 direction) is formed, and the groove 16a or the long hole slides on the linear guide portion 11. . Therefore, the moving body 3 can move up and down in a state where it is difficult to tilt in the XZ plane.

  The action point (the center of the drive action shaft 49) at which the moving force from the motor 41 acts on the slider 31 is located at the center in the left-right direction of the moving body 3 and the center in the left-right direction of the slider 31. The center line of the straight guide portion 11 is aligned in the front-rear direction (Y1-Y2 direction). Further, the center line of the straight guide part 11, the movement center line of the first moving part 16, the action point of the moving force (the center of the drive action shaft 49), and the position of the center of gravity of the moving body 3 are the same as YZ. Located in the plane and lined up in the front-rear direction. Therefore, when the slider 31 and the moving body 3 are lifted by the moving force acting on the action point, the tilting force in the XZ plane hardly acts on the moving body 3 and the slider 31. Since the movable body 3 and the slider 31 can be moved up and down while always maintaining a horizontal posture, an equal lifting force can be applied from the left and right side portions of the slider 31 to the left and right second moving portions 17. It becomes like this.

  In addition, since the moving body 3 moves up and down while maintaining a horizontal posture, the dynamic friction between the first moving unit 16 and the linear guide unit 11 is less likely to fluctuate, and between the second moving unit 17 and the curved guide unit 12. The dynamic friction is also less likely to fluctuate, and the moving body 3 can be moved up and down with a low load.

The straight guide portion 11 is a rod-shaped guide shaft having a perfectly circular cross section, extends linearly in the Z1-Z2 direction, and has an upper end portion and a lower end portion fixed to the support base 2. In the guide driving device 110 of the second embodiment, the slider 31 functions as a first moving unit. A bearing member 31 e is fixed to the slider 31. The bearing member 31e is inserted through the guide shaft of the linear guide unit 11, and the slider 31 is restrained by the linear guide unit 11 in the alignment direction (X1-X2 direction) and the front-rear direction (Y1-Y2 direction), and in the vertical direction (Z1- Z2 direction) is slidably supported only.

  On the back surface 3a of the moving body 3, a moving support bracket 117 is fixed at the center in the left-right direction. The slider 31 that functions as the first moving part and the movement support bracket 117 are connected by a pair of transmission links 36. The connecting piece 31c bent to the left and right side portions of the slider 31 and the upper end portion of each transmission link 36 are rotatably connected by a connecting shaft 37a, and the lower end portion of the transmission link 36 and the moving support bracket 117 are connected to the connecting shaft. 37b is rotatably connected.

  In the drive mechanism 30, a drive link 48 is provided between the drive arm 47 that is rotationally driven by the sector gear 46 and the slider 31. The drive arm 47 and the drive link 48 are rotatably connected by a connecting shaft 47a, and the drive link 48 and the slider 31 are rotatably connected by a drive action shaft 49. The point of action where the moving force by the power of the motor acts on the slider 31 is the center of the drive action shaft 49. The action point and the center line of the straight guide portion 11 are arranged side by side in the front-rear direction (Y1-Y2 direction), and the action point and the center line of the straight guide portion 11 are located in the same YZ plane. Yes.

  In the guide drive device 110 of the second embodiment shown in FIG. 8, when the fan gear 46 is rotated by the motor of the drive mechanism 30, the slider 31 as the first moving unit is moved along the linear guide unit 11 by the drive arm 47. Can be moved linearly. At this time, the second moving unit 17 moves following the bending guide unit 12, and the moving body 3 moves up and down along the curved locus. At this time, when the transmission link 36 rotates, a change in the distance in the front-rear direction (Y1-Y2 direction) between the movement support bracket 117 of the movable body 3 and the slider 31 is allowed.

  Also in the guide drive device 110 of the second embodiment, the action point (the center of the drive action shaft 49) at which the moving force from the motor acts on the slider 31 is the center in the left-right direction of the moving body 3, and It is located at the center of the direction and the center of the left and right transmission links 36, and this action point and the center line of the straight guide 11 are aligned in the front-rear direction (Y1-Y2 direction). Further, the center line of the linear guide portion 11, the movement center line of the slider 31, the action point of the moving force (the center of the drive action shaft 49), and the position of the center of gravity of the moving body 3 are within the same YZ plane. Located and lined up in the front-rear direction. Therefore, when the slider 31 and the moving body 3 are lifted by the moving force acting on the action point, the tilting force in the XZ plane hardly acts on the moving body 3 and the slider 31.

The guide driving device of the present invention can be modified as follows.
For example, as shown in FIGS. 4 and 5, the first moving part 16 having a groove 16 a or a long hole is provided on the back surface 3 a of the moving body 3, and the groove 16 a or the long hole slides on the linear guide part 11. The slider 31 shown in FIG. 8 and the both side surfaces of the first moving unit 16 facing the X1-X2 direction may be connected by the transmission link 36. Further, the connecting shaft 37 b that supports the transmission link 36 may be located between the first moving unit 16 and the second moving unit 17.

That is, the guide driving device according to the present invention enables the bending moving portion, which is the second moving portion 17 provided in the moving body 3, to move along the bending locus following the bending guiding portion 12 and serves as the first moving portion. It is only necessary that the slider 31 and any part of the moving body 3 are connected by the transmission link 36.
Further, the linear guide portion 11 is not limited to a guide shaft having a circular cross section, and may have a rectangular cross section, or a rail having a concave or convex cross section extending linearly in the Z1-Z2 direction. Good.
