As shown in FIG. 1, in the drive mechanism 30, the motor 41 and the gearbox 45 are fixed to the outer surface 2b facing the rear of the support base 2. As shown in FIGS. 2 and 3, a gear 43 rotated by a motor 41 and a clutch gear 44 rotated by the gear 43 are rotatably supported inside 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 of the support base 2 facing forward (Y1 direction). A support hole 46a is formed in the fan gear 46, and the support hole 46a is rotatably supported by a support shaft fixed to the inner surface of the support base 2. The tooth portion 46b of the fan gear 46 meshes with the pinion gear that rotates together with the clutch gear 44. A drive arm 47 is fixed to the fan gear 46, and a drive link 48 is rotatably supported by a connecting shaft 47a at the tip of the drive arm 47.

The power of the motor 41 is decelerated and transmitted from the pinion gear to the fan gear 46, and when the fan gear 46 rotates, the rotational power of the drive arm 47 acts on the drive action shaft 49 via the drive link 48, and the slider 31 moves. It is guided by the linear guide unit 11 and moved in the vertical direction. The point of action on which the moving force generated by the power of the motor acts on the slider 31 is the center of the drive action shaft 49. The point of action and the center line of the linear guide portion 11 are arranged side by side in the front-rear direction (Y1-Y2 direction), and the point of action and the center line of the linear guide portion 11 are located in the same YZ plane. There is.

Next, the operation of the guide drive device 10 used as the display device 1 will be described.
In FIGS. 1 and 2, the fan gear 46 is rotated clockwise, and the slider 31 is lowered along the linear guide portion 11. Since the first moving portion 16 provided on 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 portion 16 is also the most as the slider 31 descends. It has been moved to the bottom edge. Further, the second moving portion 17 is also lowered by the transmission links 36 of the transmission portions 35 provided on both sides of the slider 31. Therefore, as shown in FIGS. 5 (A) and 7 (A), the moving body 3 is in the initial posture of moving downward (Z2 direction).

The moving body 3 in the initial posture is in a posture of descending along the surface of the instrument panel or the dash board 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 or the like 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 fan gear 46 is driven in the counterclockwise direction. The rotational power of the drive arm 47 that rotates together with the fan gear 46 acts on the drive action shaft 49 located at the center of the left and right sides 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 31a and the lower bearing piece 31b 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 straight line guide portion 11 and is moved upward in a straight line locus. Then, 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. Be 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 in a state of being sandwiched inside the groove 16a of the first moving portion 16. , 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 31c on the left and right sides of the slider 31 to the second moving portion 17 via the transmission link 36, and the second moving portion 17 is guided to the curved guide portion 12. Is lifted upwards. As shown in FIGS. 7A and 7B, the sandwiching sliding portion 18 provided in the second moving portion 17 sandwiches the rail portion 14 which is the curved portion of the bending guide portion 12, and the second moving portion 17 The rail portion 14 is sandwiched by a pair of sandwiching rollers 21 provided in the above. Therefore, the second moving portion 17 moves upward along the curved locus of the rail portion 14 without causing rattling. Further, 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 between the moving body 3 and the linear guide portion 11 changes in the front-rear direction (Y1-Y2 direction). Since the linear guide portion 11 is located inside the groove 16a of the first moving portion 16, it is possible to absorb the change in the relative distance.

As shown in FIGS. 3 and 7B, when the ascending of the moving body 3 is completed and the moving body 3 is in the moving completed posture, the front surface 3b of the moving body 3 facing in the Y1 direction becomes diagonally upward toward the vehicle interior, and the front surface 3b The display screen provided on the screen faces diagonally upward.

In the display device 1 of the first embodiment, the guide drive device 10 moves the moving body 3 upward along a curved locus toward which the projecting side is directed forward (Y1 direction), and the moving body 3 is in a movement complete posture. When moving downward, it also moves along the curved locus. Due to the movement along the curved locus, the moving body 3 is moved in the vertical direction and tilted at the same time. Therefore, the movement of the moving body 3 is smooth, and it is possible to improve the quality of the moving operation of the moving body 3.

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 to operate linearly, so that the drive mechanism 30 for transmitting 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 changing the shape.

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

The point of action (center of the drive action axis 49) on which the moving force from the motor 41 acts on the slider 31 is located at the center of the moving body 3 in the left-right direction and at the center of the slider 31 in the left-right direction. , The center line of the straight line guide portion 11 is lined up in the front-rear direction (Y1-Y2 direction). Further, the center line of the linear guide portion 11, the moving center line of the first moving portion 16, the action point of the moving force (center of the driving action axis 49), and the position of the center of gravity of the moving body 3 are the same YZ. It is located in a plane and is lined up in the front-back direction. Therefore, when the slider 31 and the moving body 3 are lifted by the moving force acting on the point of action, the tilting force in the XZ plane hardly acts on the moving body 3 and the slider 31. Since the moving body 3 and the slider 31 can be moved up and down while always maintaining a horizontal posture, it is possible to apply an even lifting force to each of the left and right second moving portions 17 from the left and right side portions of the slider 31. Will be.

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

It is slidably supported only in the Z2 direction).

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

The drive arm 47 and the drive link 48 are rotatably connected by the connecting shaft 47a, and the drive link 48 and the slider 31 are rotatably connected by the drive acting shaft 49. The point of action on which the moving force generated by the power of the motor acts on the slider 31 is the center of the drive action shaft 49. The point of action and the center line of the linear guide portion 11 are arranged side by side in the front-rear direction (Y1-Y2 direction), and the point of action and the center line of the linear guide portion 11 are located in the same YZ plane. There is.

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 which is the first moving portion is moved along the linear guide portion 11 by the drive arm 47. Can be moved linearly. At this time, the second moving portion 17 moves following the bending guide portion 12, and the moving body 3 moves up and down along the bending locus. At this time, by rotating the transmission link 36, a change in the distance in the front-rear direction (Y1-Y2 direction) between the movement support bracket 117 of the moving body 3 and the slider 31 is allowed.

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

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

That is, the guide drive device of the present invention enables the curved moving portion, which is the second moving portion 17 provided on the moving body 3, to move in a curved locus following the curved guide portion 12, and becomes the first moving portion. It suffices 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 the 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.
