Description

  The present invention relates to an electronic device including a device main body mounted on a moving body such as an automobile, and a movable unit provided on the device main body so as to be rotatable around one end.

  2. Description of the Related Art Conventionally, various AV (Audio-Visual) devices as electronic devices may be attached to a vehicle as a moving body. The AV device includes a box-shaped device main body and a display unit as a movable unit that can be inserted into and removed from the device main body.

  The device main body is formed in a flat box shape, and is attached to the above-described vehicle instrument panel. The device body contains a TV tuner, a DVD (Digital Versatile Disk) player, and the like. The device main body is provided with operation units such as various operation switches and buttons on the front surface (the surface facing the user and exposed to the outside of the instrument panel).

  The display unit is formed in a flat plate shape, and includes a display panel such as an LCD (Liquid Crystal Display). The display unit displays information reproduced by the above-described DVD player and television images received by the television tuner on the display panel.

  In addition, the display unit described above is moved in and out of the device main body by a drive mechanism housed in the device main body, and is rotated around one end while being exposed to the outside of the device main body. The display unit is rotated around one end while being exposed to the outside of the device main body, so that the vehicle occupant can visually recognize the first position that can be freely inserted into and removed from the device main body and the information displayed on the display panel. The second position is displaceable.

  For this reason, in the AV device described above, the torsion coil spring that urges the display unit from the first position toward the second position, for example, in order to prevent the display unit from rattling, particularly at the second position. It has. The torsion coil spring is attached to the outer periphery of the rotating shaft provided at the aforementioned one end of the display unit. The torsion coil spring is disposed coaxially with the rotation axis through the rotation axis.

  In the AV device as the electronic device described above, the outer diameter of the rotating shaft is smaller than the thickness of the display portion, and thus the outer diameter of the torsion coil spring tends to be smaller. For this reason, the material (wire material) which comprises a torsion coil spring becomes short, and the torsion amount at the time of displacing a display part toward the said 1st position from the said 2nd position is the material (wire material) mentioned above. There was a tendency to increase relative to the total length. For this reason, when the spring constant of the torsion coil spring is determined so that the spring constant of the torsion coil spring becomes large and the display portion can be urged with a predetermined force at the second position, The force for displacing the display unit from the second position toward the first position tends to increase against the force. As described above, the conventional AV device described above tends to increase the force applied when the display unit is moved from the second position toward the first position.

  For this reason, the above-described conventional AV equipment tends to increase the reduction ratio of the motor that drives the display unit, thereby making the configuration of the power transmission unit of the motor more complicated and increasing the size of the power transmission unit. there were. In addition, since the force applied when moving the display portion has to be increased, the motor itself has tended to increase in size. Therefore, the conventional AV device tends to be large in size as a whole.

  An object of the present invention is to provide, for example, an electronic apparatus that can reduce the force required when moving a movable unit and can be downsized.

  In order to solve the above problems and achieve the object, an electronic device according to a first aspect of the present invention is supported by the device main body and the device main body so as to be rotatable around one end portion, and the one end.

In an electronic device according to an embodiment of the present invention, a large-diameter portion larger in diameter than the rotation shaft is attached to the outer periphery of the rotation shaft provided at one end of the movable unit, and a biasing means is provided on the outer periphery of the large-diameter portion. By attaching, the full length of the material (wire) which comprises a biasing means is lengthened, and the spring constant of this biasing means is made small. In this way, for example, it becomes possible to reduce the force required when displacing the movable unit from the second position toward the first position against the urging force of the urging means. Thus, the power transmission unit from the drive source can be simplified and the drive source can be downsized, and the electronic device itself can be downsized.

  A torsion coil spring may be used as the biasing means.

  In addition, when the center of the mountable area provided at one end of the movable unit and the rotation center of the rotary shaft are misaligned, the axis of the large-diameter portion is attached to the mountable area from the rotation center of the rotary shaft. It may be positioned closer to the center.

For example, when the motor 35 is driven in reverse, the first slide chassis 45 moves to the side closer to the insertion port 7 b of the device body 2, that is, the side away from the insertion port 7 b, that is, the back side of the device body 2.

  The second slide chassis 46 is made of sheet metal, and is integrally formed with a flat plate-like horizontal portion 66 and a flat plate-like vertical portion 67 erected from the edge of the horizontal portion 66 and is formed in an L shape. . In the second slide chassis 46, the horizontal portion 66 is overlaid on the fixed chassis 44, and the vertical portion 67 is overlaid on the inner surface of the peripheral plate 13. The horizontal portion 66 of the second slide chassis 46 is spaced from the fixed chassis 44 and allows the horizontal portion 55 of the first slide chassis 45 to enter between the fixed chassis 44. The vertical portion 67 of the second slide chassis 46 is spaced from the peripheral plate 13 and allows the vertical portion 56 of the first slide chassis 45 to enter between the peripheral plate 13. The second slide chassis 46 is provided closer to the insertion port 7 b than the first slide chassis 45.

  The second slide chassis 46 is provided with a plurality of guide holes 68 and connecting holes 69. The guide hole 68 passes through the horizontal portion 66 and extends linearly along the depth direction Y.

That is, the connection hole 69 is provided at the end of the horizontal portion 66 near the first slide chassis 45. The connection hole 69 passes through the horizontal portion 66. The connection hole 69 extends linearly along the width direction X of the device body 2.

  The second slide chassis 46 described above is movable along the depth direction Y by the guide hole 68 and the boss 70 that has entered the guide hole 68. In addition, a coil spring 71 as a second urging means is stretched between the second slide chassis 46 and the bottom plate 12 of the second fixed chassis 9. The second slide chassis 46 is biased by the coil spring 71 in a direction away from the insertion port 7 b, that is, toward the back of the device body 2.

  Further, the end portion of the upper connecting arm 43 is rotatably connected to the vertical portion 67 of the second slide chassis 46 described above.

  The connection chassis 47 is made of sheet metal and is formed in a flat plate shape. The connection chassis 47 is provided between the first slide chassis 45 and the second slide chassis 46. In the illustrated example, the connection chassis 47 is provided on the first slide chassis 45 and below the second slide chassis 46. The connection chassis 47 is attached to the bottom plate 12 of the second fixed chassis 9 so as to be rotatable around an edge 47a near the insertion port 7b.

  The connection chassis 47 is provided with a pair of slide protrusions 72 and 73. One slide protrusion 72 is formed so as to protrude from the connection chassis 47 toward the first slide chassis 45, and enters the slide hole 59 provided in the first slide chassis 45. Can be moved freely.

  The other slide projection 73 is formed so as to protrude from the connection chassis 47 toward the second slide chassis 46, and enters the connection hole 69 provided in the second slide chassis 46. Can be moved freely.

  The connecting chassis 47 described above does not rotate around the edge 47a (that is, the rotation is restricted) when the slide protrusion 72 moves within the linear portion 62 of the slide hole 59. When the slide protrusion 72 moves in the arc portion 63 of the slide hole 59, the connection chassis 47 rotates around the edge portion 47a (that is, depending on the position of the slide protrusion 72 in the arc portion 63). ,Rotate). Further, when the slide projection 72 moves from the straight portion 62 toward the arc portion 63 and the slide projection 72 moves the arc portion 63 away from the straight portion 62, the connection chassis 47 is centered on the edge portion 47a. The second slide chassis 46 rotates in a direction to press in the direction approaching the insertion port 7b.

  With the configuration described above, in the moving unit 37, when the motor 35 is driven to rotate forward, for example, the first slide chassis 45 approaches the insertion port 7b. When the slide protrusion 72 moves in the arc portion 63, the connection chassis 47 rotates around the edge portion 47a, and the second slide chassis 46 moves in a direction approaching the insertion port 7b. Further, the slide projections 52 and 53 of the lower connecting arm 42 move in the slide holes 40 and 41, so that the moving unit 37 serves as the operation unit 4, and the operation unit 4 serves as the front surface 2a of the device body 2 (shown in FIG. 20). 14 and FIG. 15 that covers the cover), the insertion / ejection position shown in FIGS. 20 and 21 where the operation unit 4 opens both the opening 7a and the insertion port 7b, and the operation unit 4 is open. It moves to the operation position shown in FIG. 22 and FIG. 23 which opens the part 7a and covers a part of the insertion port 7b in order. The front surface 2a is a surface facing the occupant (user) of the device main body 2.

  Further, in the moving unit 37, when the motor 35 is driven in reverse, for example, the first slide chassis 45 is separated from the insertion port 7b. When the slide protrusion 72 moves in the arc portion 63, the connecting chassis 47 rotates around the edge portion 47a, and after the second slide chassis 46 moves away from the insertion port 7b, the slide protrusion 72 moves in the linear portion 62. And the second slide chassis 46 stops. Further, the slide protrusions 52 and 53 of the lower connecting arm 42 move in the slide holes 40 and 41, and the moving unit 37 moves the operation unit 4 to the operation position, the insertion / ejection position, and the cover position in order. Moving.

  Each of the plurality of transmission gears 38 is rotatably provided on the bottom plate 12 of the second fixed chassis 9. The plurality of transmission gears 38 mesh with each other, one meshes with the worm 39, and the other meshes with the interlocking gear 36. The transmission gear 38 transmits the rotational driving force of the motor 35 to the interlocking gear 36, that is, the first slide chassis 45.

  Next, the operation of the AV device 1 having the above-described configuration will be described. First, as shown in FIGS. 14 and 15, the display unit 3 is positioned at the accommodation position, and the operation unit 4 is positioned at the cover position. In this state, the traveling gear 23 meshes with the end of the rack 22 of the first drive unit 5 on the back side of the device main body 2, and the display panel 3a faces downward.

  Furthermore, as shown in FIG. 9, the first slide chassis 45 of the second drive unit 6 is positioned at the back side of the device body 2, that is, at a position away from the insertion port 7b, and the second slide chassis 46 is inserted into the insertion port 7b. Away from. As shown in FIG. 8, the slide protrusion 52 of the lower connecting arm 42 is provided on the end portion of the first slide hole 40 on the side away from the insertion port 7 b and the vertical portion 56 of the first slide chassis 45. It is located at the end of the inclined portion 65 of the support hole 61 near the insertion port 7b. Further, the slide protrusion 53 of the lower connecting arm 42 is located at the end of the second slide hole 41 on the side away from the insertion port 7b. The slide projection 72 of the connection chassis 47 is located at the end of the linear portion 62 of the slide hole 59 provided on the horizontal portion 55 of the first slide chassis 45 near the insertion port 7b.

  In this state, when the display unit 3 is discharged out of the device main body 2, first, the display unit 3 for discharging the display unit 3 out of the device main body 2 (for drawer) out of the switch 17 is first viewed. The switch 17 for positioning is operated. Then, the motor 35 of the 2nd drive part 6 carries out normal rotation drive, for example. Then, the driving force of the motor 35 is transmitted to the first slide chassis 45 by the transmission gear 38 and the interlocking gear 36, and the first slide chassis 45 gradually moves toward the insertion port 7b. The first slide chassis 45 gradually enters between the fixed chassis 44 and the connection chassis 47 and gradually enters between the fixed chassis 44 and the second slide chassis 46.

  Then, the slide protrusion 72 provided on the connection chassis 47 moves in the linear portion 62 of the slide hole 59 provided on the first slide chassis 45 in a direction gradually approaching the arc portion 63. For this reason, the connection chassis 47 maintains a stopped state without rotating around the edge 47a.

  Further, since the slide protrusion 52 of the lower connecting arm 42 is located in the inclined portion 65 of the support hole 61 provided in the first slide chassis 45, it does not move relative to the first slide chassis 45. The inside of the horizontal portion 48 of the first slide hole 40 provided in the peripheral plate 13 is moved. Further, the slide protrusion 53 of the lower connecting arm 42 moves in the horizontal portion 50 of the second slide hole 41 provided in the peripheral plate 13. For this reason, the lower connecting arm 42 is gradually discharged out of the device main body 2. For this reason, the lower end portion of the operation unit 4 gradually protrudes forward from the front surface 2a of the device body 2, and the operation unit 4 is gradually displaced upward.

  Then, as shown in FIGS. 16 and 17, the operation unit 4 opens the opening 7a while covering the insertion port 7b.

  Then, as shown in FIG. 10, the slide protrusion 52 of the lower connecting arm 42 enters the inclined portion 49 of the first slide hole 40 and the inclined portion 65 of the support hole 61 of the first slide chassis 45, and the inclined portion Displace upward along the lines 49 and 65. Further, the slide protrusion 53 of the lower connection arm 42 enters the inclined portion 51 of the second slide hole 41 and is displaced downward along the inclined portion 51. Since the slide protrusion 52 is provided at the end of the lower connection arm 42 and the slide protrusion 53 is provided at the center of the lower connection arm 42, one end of the lower connection arm 42 near the insertion port 7b of the device main body 2 is formed. Displaced downward, the lower end of the operation unit 4 is displaced downward. As shown in FIGS. 20 and 21, the operation unit 4 is positioned at an insertion / ejection position where both the opening 7 a and the insertion port 7 b are opened. At the insertion / ejection position, the aforementioned DVD video and the like are taken in and out.

  As shown in FIGS. 16 and 17, when the operation unit 4 opens the opening 7a while covering the insertion port 7b, the motor 21 of the first drive unit 5 is driven to rotate forward. Then, the traveling gear 23 travels on the rack 22, and the traveling gear 23 gradually approaches the opening 7a. Then, the display unit 3 is gradually discharged out of the device body 2. Then, as indicated by a two-dot chain line in FIG. 19, the display unit 3 is discharged out of the device body 2, and the display panel 3 a is positioned at a reference position facing downward.

  And while the motor 21 mentioned above stops, the motor 27 of the 1st drive part 5 drives forward rotation, for example. Then, the display unit 3 is rotated about the one end 3c, and the display unit 3 is gradually started up so that the display panel 3a gradually faces upward as shown in FIGS. Then, as shown in FIGS. 20 and 21, the display unit 3 is positioned at the visual recognition position. At this viewing position, the display unit 3 is biased by the torsion coil spring 30 in a direction in which the display panel 3a faces upward (that is, toward the viewing position).

  Thus, as shown in FIGS. 20 and 21, the display unit 3 is positioned at the visual recognition position, and the operation unit 4 is positioned at the insertion / ejection position. And the motor 27 of the 1st drive part 5 stops. The display unit 3 displays information such as a DVD player and a TV tuner on the display panel 3a.

  Further, when the motor 35 of the second drive unit 6 is further driven to rotate forward, the slide protrusion 72 of the connection chassis 47 enters the arc portion 63 of the slide hole 59 of the first slide chassis 45 as shown in FIG. Further, when the motor 35 is driven to rotate forward, the first slide chassis 45 further approaches the insertion port 7b as shown in FIG. 12, and the slide protrusion 72 enters the back of the arc portion 63. Then, the connection chassis 47 rotates around the edge 47 a against the urging force of the coil spring 71. Then, since the slide protrusion 73 has entered the connection hole 69, the connection chassis 47 presses the second slide chassis 46 toward the insertion port 7 b against the urging force of the coil spring 71. Then, the second slide chassis 46 approaches the insertion port 7b.

  On the other hand, when the operation unit 4 is positioned at the insertion / ejection position, the slide protrusion 52 enters the horizontal portion 64 of the support hole 61 of the first slide chassis 45. Further, the slide protrusions 52 and 53 are positioned at the end portions of the slide holes 40 and 41 near the insertion port 7b. For this reason, even if the first slide chassis 45 further moves, as shown in FIG. 12, the slide protrusion 52 moves along the horizontal portion 64 of the support hole 61, and the lower connection arm 42 stops.

  Further, when the second slide chassis 46 is brought close to the insertion port 7b, the rotation fulcrum (the other end 43b) of the upper connection arm 43 is discharged to the front of the device body 2. In this way, the other end 42b of the lower connecting arm 42 is stopped, and the rotation fulcrum (the other end 43b) of the upper connecting arm 43 is discharged to the front of the device main body 2. Therefore, the upper end of the operation unit 4 from the insertion / discharge position. Is displaced upward. Thus, as shown in FIGS. 22 and 23, the operation unit 4 is positioned at the operation position covering the insertion port 7b. At this operation position, information displayed on the display unit 3 is selected by operating the operation unit 4 or the touch panel. Further, when the DVD video is taken in / out, the operation unit 4 and the touch panel are operated to drive the motor 35 in the reverse direction to position the operation unit 4 at the insertion / ejection position. Further, when the operation unit 4 is moved from the operation position to the cover position and the display unit 3 is moved to the accommodation position, the motors 21, 27, and 35 are driven in the opposite direction. That is, the motors 21, 27, and 35 are driven in reverse.

  In addition, when the AV device 1 puts the display unit 3 in the device main body 2 and puts the DVD video in and out of the device main body 2, the AV device 1 keeps the display unit 3 in the device main body 2 and the second drive unit. 6 is operated, and the operation unit 4 is moved over the cover position shown in FIGS. 14 and 15 and the insertion / ejection position shown in FIGS. 20 and 21. Also at this time, the second drive unit 6 is operated as described above.

  According to the present embodiment, the large-diameter portion 33 is attached to the outer periphery of the rotating shaft 14 provided at the one end portion 3 c of the display unit 3, and the large-diameter portion 33 is passed through the torsion coil spring 30. 30 is attached to the outer periphery of the large-diameter portion 33. For this reason, the inner large diameter of the torsion coil spring 30 becomes larger, the material (wire material) constituting the torsion coil spring 30 becomes longer, and the display unit 3 is displaced from the viewing position toward the reference position. The torsion amount of the torsion coil spring 30 is relatively small with respect to the total length of the material (wire) described above.

  For this reason, when the spring constant of the torsion coil spring 30 is determined so that the spring constant of the torsion coil spring 30 becomes small and the display unit 3 can be urged with a predetermined force at the visual recognition position, The force for displacing the display unit 3 from the visual recognition position toward the reference position can be weakened against the urging force. For this reason, the AV device 1 can weaken the force applied when the display unit 3 is moved from the viewing position toward the reference position.

  For this reason, the reduction ratio of the motor 35 for moving the display unit 3 can be reduced, the mechanism of the portion for transmitting the power from the motor 35 can be simplified, and the mechanism for transmitting the power can be simplified. Miniaturization can be achieved.

  Furthermore, since the force applied when the display unit 3 is moved from the visual recognition position toward the reference position can be reduced, the size of the motor 35 itself can be reduced. Further, a torsion coil spring 30 is used as the biasing means.

  Therefore, it is possible to reduce the force required when moving the display unit 3 and to reduce the overall size of the AV device 1.

  When the center P2 of the attachable region R provided at the one end 3c of the display unit 3 and the axis P1 of the rotary shaft 14 are displaced, the axis P3 of the large-diameter portion 33 is moved away from the rotary shaft 14. It is positioned closer to the center P2 of the mountable region R than the axis P1. For this reason, it is possible to reliably increase the diameter of the torsion coil spring 30 in a limited space of the attachable region R.

  The width H of the attachable region R is substantially equal to the outer diameter of the torsion coil spring 30. Therefore, it is possible to reliably increase the diameter of the torsion coil spring 30 in a limited space of the attachable region R.

  Next, the inventors of the present invention confirmed the effects of the present invention. The results are shown in Table 1 below.

  In the comparative example of Table 1, the inner diameter of the torsion coil spring 30 is made equal to the outer diameter of the rotating shaft 14. In the comparative example, the material is SWP-B (Piano wire type B defined in JIS (Japanese Industrial Standards) G3522), the wire has a diameter of 1.2 mm, the total length of the wire is 132 mm, and the inner diameter is 4 mm. A torsion coil spring 30 of 2 mm was used.

  In the product of the present invention shown in Table 1, the inner diameter of the torsion coil spring 30 is made equal to the outer diameter of the large diameter portion 33 as described in the above-described embodiment. In the product of the present invention, the torsion coil spring 30 having the material SWP-B, the wire rod diameter of 1.1 mm, the wire rod length of 322 mm, and the inner diameter of 8.9 mm was used.

  In the experiment shown in Table 1, the moment of the urging force by which the torsion coil springs 30 at both the reference position and the visual recognition position urge the display unit 3 was measured.

  According to Table 1, the moment of the biasing force at the visual recognition position of the product of the present invention is substantially equal to the moment of the biasing force at the visual recognition position of the comparative example, and the moment of the biasing force at the reference position of the inventive product is the reference of the comparative example. Since the moment of the urging force of the position is smaller than the comparative example, it is clear that the resistance of the torsion coil spring 30 when the product of the present invention moves the display unit 3 from the visual recognition position to the reference position is small. That is, it is clear from the comparative example that the product of the present invention can weaken the force for displacing the display unit 3 from the viewing position toward the reference position against the biasing force of the torsion coil spring 30 described above. became.

  In the above-described embodiment, the AV apparatus 1 including a DVD player is shown. However, in the present invention, an electronic device including an electronic unit other than the DVD player may be used.

  In the embodiment described above, the display unit 3 having the display panel 3a as the display surface is shown as the movable unit. However, in the present invention, the movable unit may be various electronic units other than the display unit 3.

  In the embodiment described above, the torsion coil spring 30 is used as the biasing means. However, in the present invention, various springs other than the torsion coil spring 30 and elastic bodies such as rubber may be used as the biasing means.

  Furthermore, in the embodiment described above, the rotating shaft 14 and the large-diameter member 29 are separated. However, in the present invention, as shown in FIGS. 24 and 25, a rotary shaft member 80 in which the rotary shaft 14 and the large-diameter member 29 are integrated may be used. 24 and 25, the same parts as those in the above-described embodiment are designated by the same reference numerals, and the description thereof is omitted. 24 and 25, the boundary between the rotating shaft 14 and the large-diameter member 29 is indicated by a dotted line. Of course, the rotary shaft member 80 is attached to one end 3 c of the display unit 3. Of course, in the rotating shaft member 80, the large-diameter portion 33 is integrated with the outer periphery of the rotating shaft 14.

  24 and 25, the force for displacing the display unit 3 from the visual recognition position toward the reference position is weakened against the urging force of the torsion coil spring 30 as in the above-described embodiment. can do.
