The moving body 3 has a case that holds the display unit, and the back surface of the case serves as the back surface 3 a of the moving body 3 . As shown in FIG. 4, a first moving portion 16 is provided in the central portion that bisects the moving body 3 in the horizontal direction (X1-X2), and second moving portions 16 are provided on the X1 side and the X2 side with the first moving portion 16 interposed therebetween. A moving part 17 is provided. The first moving part 16 and the second moving part 17 are formed integrally with the case of the moving body 3, or fixed to the rear surface 3a of the moving body 3 by means such as screwing. The distance from the first moving part 16 to the second moving part 17 on the right side is the same as the distance from the first moving part 16 to the second moving part 17 on the left side. The second moving part 17 is a bending moving part and the first moving part 16 is a guiding moving part.

As shown in FIGS. 4 and 5A and 5B, the first moving portion 16 is a first sliding portion that protrudes rearward (in the Y2 direction) from the back surface 3a of the moving body 3. A groove 16a extending in the front-rear direction (Y1-Y2 direction) is formed in the moving portion 16. As shown in FIG.

As shown in FIGS. 7A and 7B, the pair of pinching rollers 21 pinch the rail portion 14 from the front-rear direction (Y1-Y2 direction), and the second moving portion 17 moves along the curved trajectory of the rail portion 14. It is designed to be able to move along the line without rattling.

As shown in FIGS. 2, 3 and 4, the guide driving device 10 is provided with a driving mechanism 30. As shown in FIG. A slider 31 is provided in the drive mechanism 30 . The slider 31 is formed by pressing a metal plate. An upper bearing piece 31a bent in the Y1 direction from the upper end and a lower bearing piece 31b bent in the Y1 direction from the lower end are provided at the center of the slider 31 in the left-right direction. As shown in FIGS. 4 and 5(A) and (B), the sliding bearing member 32 is held by the upper bearing piece 31a and the lower bearing piece 31b, and the linear guide portion 11 is vertically held sliding bearing. It is slidably inserted into the member 32 .

The upper bearing piece 31a is in close contact with the upper surface of the first moving part 16 provided on the back surface 3a of the moving body 3, and the lower bearing piece 31b is in close contact with the lower surface of the first moving part 16. 16 is sandwiched between the upper bearing piece 31a and the lower bearing piece 31b without any play in the vertical direction.

As shown in FIGS. 2, 3 and 4, a transmission portion 35 is provided between the right and left end portions of the slider 31 and the left and right second moving portions 17 . Each transmission portion 35 is provided with a transmission link 36 . The upper portion of the transmission link 36 is rotatably connected to connecting pieces 31c bent to the left and right sides of the slider 31 via a connecting shaft 37a, and the lower portion of the transmission link 36 is connected to each second moving portion 17. They are rotatably connected via a shaft 37b.

As shown in FIG. 1, the drive mechanism 30 has a motor 41 and a gear box 45 fixed to the rearward outer surface 2b of the support base 2. As shown in FIG. As shown in FIGS. 2 and 3, inside the gear box 45, a gear 43 rotated by the motor 41 and a clutch gear 44 rotated by the gear 43 are rotatably supported. 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 46 a is formed in the fan 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 toothed portion 46 b 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 at the tip of the drive arm 47 by a connecting shaft 47a. As shown in FIG. 4, a driving shaft 49 extending rearward (Y2 direction) is fixed to the lower portion of the slider 31, and the lower end of the driving link 48 is rotatably connected to the driving shaft 49. As shown in FIG.

When the power of the motor 41 is decelerated and transmitted from the pinion gear to the sector gear 46, and the sector gear 46 rotates, the rotational force 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 portion 11 and moved in the vertical direction. The point of action at which the moving force generated by the power of the motor acts on the slider 31 is the center of the driving 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 driving device 10 used as the display device 1 will be described.
1 and 2, the sector gear 46 is rotated clockwise, and the slider 31 is lowered along the linear guide portion 11. In FIG. 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 also moves to its maximum position as the slider 31 descends. It has been moved to the bottom. 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 assumes an initial posture of moving downward (Z2 direction).

The moving body 3 in the initial posture is in a posture lowered along the surface of the instrument panel or 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 top 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 counterclockwise. The rotational force of the drive arm 47 that rotates together with the sector gear 46 acts from the drive link 48 to the drive action shaft 49 located in the left-right central portion of the slider 31, and the slider 31 is lifted. As shown in FIGS. 5A and 5B, a 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 through the linear guide portion 11. Therefore, the slider 31 is guided by the linear guide portion 11 and moved upward along a linear locus. Since the upward moving force acts 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 moves 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 , moves upward while being restrained without moving in the horizontal direction.

The upward moving force of the slider 31 is transmitted from the connecting pieces 31 c 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 by the curved guide portion 12 . lifted upwards. As shown in FIGS. 7(A) and 7(B), the clamping/sliding portion 18 provided in the second moving portion 17 clamps the rail portion 14 which is the curved portion of the curved guide portion 12, and the second moving portion 17 is moved. The rail portion 14 is nipped by a pair of nipping rollers 21 provided on the . Therefore, the second moving portion 17 moves upward along the curved trajectory of the rail portion 14 without rattling. The moving body 3 also moves upward along the curved trajectory 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) between the moving body 3 and the linear guide portion 11 changes. Since the linear guide portion 11 is positioned inside the groove 16a of the first moving portion 16, relative changes in distance can be absorbed.

As shown in FIGS. 3 and 7(B), when the moving body 3 has finished rising and is in the movement completion posture, the front surface 3b of the moving body 3 facing in the Y1 direction is directed diagonally upward toward the interior of the vehicle. The display screen provided in the is directed obliquely upward.

In the display device 1 of the first embodiment, the guide driving device 10 moves the moving body 3 upward along a curved trajectory in which the protruding side is directed forward (Y1 direction) to assume the movement completion posture. When moving downward, it also moves along the curved trajectory. By moving along the curved trajectory, the moving body 3 moves vertically and tilts at the same time. 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 driving device 10, the moving body 3 moves along a curved trajectory, but the slider 31 moves linearly while being guided by the linear guide portion 11. Therefore, the driving 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 becoming complicated.

The moving body 3 has a first moving part 16 in the center of the left and right, and as shown in FIG. A groove 16a or an elongated hole is formed, or a groove 16a or an elongated hole having a height dimension in the vertical direction (Z1-Z2 direction) is formed, and this groove 16a or an elongated hole slides on the linear guide portion 11. . Therefore, the moving body 3 can move up and down within the XZ plane in a state where it is difficult to tilt.

The action point (the center of the driving action shaft 49) where 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. , 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 movement center line of the first moving portion 16, the action point of the moving force (the center of the driving action shaft 49), and the position of the center of gravity of the moving body 3 are the same YZ. They are located in a plane and aligned in the front-rear direction. Therefore, when the slider 31 and the moving body 3 are lifted by the moving force acting on the point of action, almost no tilting force acts on the moving body 3 and the slider 31 within the XZ plane. Since the moving body 3 and the slider 31 can be moved up and down while maintaining a horizontal posture at all times, an equal lifting force can be applied to each of the left and right second moving parts 17 from both left and right sides of the slider 31. become.

Further, since the moving body 3 moves up and down while maintaining a horizontal posture, the dynamic friction between the first moving portion 16 and the linear guide portion 11 is less likely to fluctuate, and the friction between the second moving portion 17 and the curved guide portion 12 is reduced. Dynamic friction also becomes less likely to fluctuate, making it possible to move the moving body 3 up and down with a low load.

FIG. 8 shows a display device 101 using the guide drive device 110 of the second embodiment of the invention.

In the second embodiment shown in FIG. 8, members having the same functions as those of the guide driving device 10 and the display device 1 of the first embodiment will be described using the same reference numerals and the same names.

The guide driving device 110 shown in FIG. 8 also has the second moving parts 17 on both left and right sides of the rear surface 3 a of the moving body 3 . The second moving part 17 is formed separately from the moving body 3 and fixed to the rear surface 3a by screwing. A clamping sliding portion 18 is fixed to each of the second moving portions 17, and a sliding concave portion 18a formed in the clamping sliding portion 18 is a rail portion of the curved guide portion 12 (not shown in FIG. 8).

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

A moving support bracket 117 is fixed to the rear surface 3 a of the moving body 3 at the center in the left-right direction. A pair of transmission links 36 are connected between the slider 31 functioning as the first moving part and the movement support bracket 117 . The connecting pieces 31c bent to the right and left sides of the slider 31 and the upper ends of the respective transmission links 36 are rotatably connected by connecting shafts 37a. 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 fan gear 46 and the slider 31 . The drive arm 47 and the drive link 48 are rotatably connected by a connecting shaft 47 a , and the drive link 48 and the slider 31 are rotatably connected by a driving action shaft 49 . The point of action at which the moving force generated by the power of the motor acts on the slider 31 is the center of the driving 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 drive arm 47 moves the slider 31, which is the first moving portion, along the linear guide portion 11. can be moved in a straight line. At this time, the second moving part 17 moves following the curved guide part 12, and the moving body 3 moves up and down along the curved trajectory. At this time, the rotation of the transmission link 36 allows a change in the distance between the movement support bracket 117 of the moving body 3 and the slider 31 in the front-rear direction (Y1-Y2 direction).

Also in the guide driving device 110 of the second embodiment, the action point (the center of the driving action shaft 49) where the moving force from the motor acts on the slider 31 is the center of the moving body 3 in the left-right direction and the left and right sides of the slider 31. Located at the center of the direction and the center of the left and right transmission links 36, this 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 movement center line of the slider 31, the action point of the movement force (the center of the drive action shaft 49), and the position of the center of gravity of the moving body 3 are all within the same YZ plane. located and aligned in the front-to-back direction. Therefore, when the slider 31 and the moving body 3 are lifted by the moving force acting on the point of action, almost no tilting force acts on the moving body 3 and the slider 31 within the XZ plane.

The guide drive device of the present invention can be modified as follows.
For example, as shown in FIG. 4 and FIG. 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.
