Description

  The present invention relates to a display apparatus, and more particularly to a technique for storing monitors having different aspect ratios in a casing so that the monitors can be pulled out without increasing the size of the apparatus.

  In recent years, monitors used in in-vehicle devices such as navigation devices have become larger in order to improve visibility and operability as a touch panel, and large-sized wide screens with an aspect ratio of 16: 9 have become mainstream. ing.

Such a large wide screen requires more space in the width direction than a conventional normal monitor with an aspect ratio of 4: 3. Therefore, when the monitor panel M is housed, as shown in FIG. It is necessary to devise such that it is in the depth direction, and when it is used, it is discharged from the housing in the horizontal direction, then raised in the vertical direction, and further rotated from there in the normal use state (for example, , See Patent Document 1 below).
Japanese Patent Laid-Open No. 11-308553

  By the way, considering that the monitor panel M protrudes toward the vehicle interior, it is necessary to reduce the horizontal discharge stroke, that is, the slide amount of the monitor panel M as much as possible.

  However, in the above-described prior art, in order to use the monitor panel M by pulling it out of the housing, the monitor panel M stored in the depth direction is completely discharged, and then the monitor is started up and rotated. Because of the order, for example, as shown in FIG. 6, it is necessary to increase the slide amount of the monitor panel M as the monitor becomes larger (see FIG. 6A).

  On the other hand, if an attempt is made to fit the enlarged monitor panel M within the slide amount of a small monitor panel (see FIG. 6A), the panel will collide with the housing when the monitor panel M is raised (see FIG. 6A). (Refer FIG.6 (b)). Therefore, in practice, the larger the size of the monitor panel M, the more the monitor panel M protrudes toward the passenger compartment, and the larger the difference S in the slide amount from the smaller monitor panel M (FIG. 6 (c)). )reference). For this reason, since the conventional mechanism can only handle up to about 7 inches with a wide panel, there has been a demand for a display device that can employ a large-sized wide panel while suppressing the amount of sliding.

  The present invention has been proposed in order to improve the above-described problems of the prior art, and its purpose is to provide a horizontal mechanism as a mechanism for extracting a large monitor whose monitor panel length exceeds the housing width from the housing. It is an object of the present invention to provide a display device that allows a monitor panel to be extracted from a housing without lengthening the discharge stroke in accordance with the monitor size by combining the direction discharge mechanism and the rotation mechanism in the monitor plane direction.

In order to achieve the above object, in order to achieve the above object, the invention according to claim 1 is a display device capable of storing display units having different aspect ratios in a casing, and the display unit is arranged in a long side direction from the casing. rotating and sliding means for discharging and housed, during the discharge of the display portion, a rotation means for substantially 90 degrees rotation of said display unit in a horizontal direction the back central portion as an axis of the display unit, the display unit to And tilting means for raising the display unit in the vertical direction.

In the aspect as described above, the display unit can be rotated around the center of the back surface of the display unit by the rotation unit provided between the slide unit and the tilt unit. Without completely discharging the display unit from the body, the rotating means can be operated even when the end on the back side is left in the casing.

  According to a second aspect of the present invention, in the first aspect of the invention, the slide means does not discharge all of the display unit from the casing, and the display unit is rotated when the display unit is rotated by the rotating unit. A part of the display unit is left in the casing in a range in which the rear end of the unit does not contact the casing.

  In the aspect as described above, the sliding amount of the sliding means increases with the size of the display unit by leaving a part of the display unit in the casing in a range where the back end of the display unit does not contact the casing. For example, a wide 8-inch monitor can be accommodated, for example, equivalent to a wide 7-inch monitor. As a result, it becomes easy to store a monitor having a size exceeding 7 inches wide as a vehicle-mounted in-dash mounting type video device.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, at least one of the left and right end portions on the back side of the display unit housed in the housing is rotated when the display unit is rotated. Further, a notch portion is provided so that a rear side end portion of the display portion does not contact the housing.

  In the above-described aspect, since the notch is provided in at least one of the left and right end portions of the display portion, the end portion on the back side can be removed without completely discharging the display portion from the housing by the sliding means. Even if the rotating means is left acting in the housing, it is possible to prevent the rear end of the display unit from contacting the housing or the like.

  As described above, according to the present invention, as a mechanism for pulling out a large monitor whose monitor panel length exceeds the casing width from the casing, a combination of a horizontal discharging mechanism and a rotating mechanism in the monitor plane direction is used. The monitor panel can be extracted from the housing without lengthening the stroke according to the monitor size.

  Next, the best mode for carrying out the present invention (hereinafter referred to as the present embodiment) will be specifically described with reference to the drawings.

That is, the slider 42 is positioned at the innermost part of the housing 2 on the guide rail 41 when the monitor panel 3 is stored (see FIG. 2C), and when the monitor panel 3 is used, the slider 42 is on the exit side. It is comprised so that it may be located in an edge part (refer FIG.2 (d)). Even in the state where the slider 42 is positioned at the outlet side end of the housing 2 as described above, as shown in FIG. 2 It will be in the state where it was not pulled out completely from the inside.

  Next, the slide drive of the slide mechanism unit 4 will be described. The slide base 40 is provided with a motor 43 as a driving force for sliding the slide base 40 on the front right side (the upper side in FIGS. 2B to 2D). Further, the worm gear 44, the gears 45 to 48 and the pinion gear are attached to the motor 43. 49 is attached. Then, the power of the worm gear 44 is gradually decelerated through the gears 45 to 48 and transmitted to the pinion gear 49, and the pinion gear 49 meshes with the rack gear 2 a provided in the depth direction on the ceiling portion of the housing 2. Thus, the slide base 40 is configured to slide in the depth direction of the housing 2.

(2) Monitor panel rotation mechanism unit The monitor panel rotation mechanism unit 5 rotates the monitor panel 3 pulled out from the housing 2 as described above by 90 degrees in the plane direction, and extends the normal use direction, that is, the lateral direction. On the side, it is a means for setting the vertical (depth of the casing 2) direction to a short side state. As shown in the side view (a) and the plan view (b) of FIG. 3, the monitor panel rotation mechanism 5 includes a monitor plate 51 provided at a connection portion between the slide base 40 and the monitor panel 3, and the monitor plate. A monitor mounting plate 52 that supports the monitor panel 3 and a plate gear 53 that rotates by receiving the drive of a gear described later is provided with the monitor plate 51 interposed between the monitor plate 51 and the shaft 51.

  The monitor mounting plate 52 is locked to the plate gear 53 by three shafts 52a, 52b, and 52c that penetrate the monitor plate 51 sandwiched therebetween. That is, when the plate gear 53 is rotated by driving a gear, which will be described later, the monitor mounting plate 52 is also rotated in synchronization therewith. The monitor panel 3 fixed to the monitor mounting plate 52 is also configured to rotate.

  Next, rotation driving of the monitor panel rotation mechanism unit 5 will be described. That is, the monitor plate 51 is provided with a motor 54 having a worm gear 55, and gears 56 to 58 that transmit power while gradually decelerating from the worm gear 55 are provided, and the plate gear 53 rotates at the final stage. Is configured to do. By the rotation of the plate gear 53, the monitor panel 3 is rotated 90 degrees on the plane as shown in FIG.

(3) Tilt Mechanism Unit The tilt mechanism unit 6 is a means for raising the monitor panel 3 in such a state so that the monitor 3a is on the front side. As shown in the plan view (a) and the side view (b) of FIG. 4, the tilt mechanism unit 6 includes a slide base 40 as a rotation center axis of the monitor plate 51, a gear 30 that supports the monitor plate 51, and a slide base 40. , A worm gear 61 and gears 62 to 69 directly connected to the motor 60.

  The tilt mechanism 6 is driven such that the power of the motor 60 is transmitted from the worm gear 61 to the gears 62 to 68 while gradually decelerating, and the gear 68 meshes with the gear 69 to rotate the monitor plate 51. As the monitor plate 51 rotates, as shown in FIG. 4C, the monitor panel 3 stands up in the vertical direction that is in use.

[Action]
The display device 1 having the above-described configuration operates in response to an operation start instruction by a user using a switch, a remote control, or the like provided in the apparatus or an instruction such as start of a vehicle engine or guidance of a car navigation device. Start.

  First, the slide mechanism unit 4 slides the monitor panel 3 accommodated in a horizontal state with the monitor side down and the long side in the depth direction with respect to the housing 2, and pulls out the monitor panel 3. More specifically, as shown in plan views (c) and (d) of FIG. 2, the slide mechanism unit 4 attached to the back side of the monitor panel 3 (the surface opposite to the monitor 3 a) is attached to the slide base 40. As the attached motor 43 rotates, the worm gear 44 rotates, and this power is transmitted while the gears 45 to 48 and the pinion gear 49 are gradually decelerated. Then, the pinion gear 49 meshes with the rack gear 2a provided in the depth direction in the ceiling portion of the casing 2, and the slide base 40 slides toward the front side (vehicle interior direction) of the casing 2.

  At this time, the slide base 40 is provided on both the left and right sides and slides the guide rail 41 via the slider 42. Further, the slider 42 moves from the innermost part of the housing 2 on the guide rail 41 (see FIG. 2C) to the outlet side end of the housing 2 (see FIG. 2D). Even in the state where the slider 42 is positioned at the outlet side end of the housing 2 as described above, as shown in FIG. 2 Not completely pulled out from inside.

  Next, the monitor panel rotating mechanism unit 5 acts to rotate the monitor panel 3 pulled out from the housing 2 by 90 degrees in the plane direction, and the vertical direction (housing 2) The depth) direction is set to the short side. Specifically, as shown in the side view (a) and plan view (b) of FIG. 3, the worm gear 55 is rotated by the rotation of the motor 54 provided on the monitor plate 51, and this power is gradually decelerated. While being transmitted to the gears 56 to 58, the plate gear 53 rotates at the final stage.

  Due to the rotation of the plate gear 53, the monitor mounting plate 52 locked by the three shafts 52a, 52b, 52c passing through the monitor plate 51 is rotated, and as a result, as shown in FIG. As described above, the monitor panel 3 rotates 90 degrees on the plane. At this time, as described above, a part of the back side of the monitor panel 3 is not completely pulled out from the inside of the housing 2, but the notch 3 b is provided at the left and right ends of the back side of the monitor panel 3. Therefore, even if the monitor panel 3 is rotated in such a state, the corners of the panel do not come into contact with the housing 2 or the like.

  Next, the tilt mechanism unit 6 is actuated to raise the monitor panel 3 in a state protruding as described above so that the monitor 3a is on the front side. That is, as shown in the plan view (a) and the side view (b) of FIG. 4, when the motor 60 attached to the slide base 40 rotates, the worm gear 61 directly connected thereto rotates, and this power is It is transmitted while being gradually decelerated through the gears 62-68.

  Then, the gear 68 is driven to mesh with the gear 69 to rotate the monitor plate 51. Then, as the monitor plate 51 rotates, the monitor panel 3 rises in the vertical direction in use as shown in FIG.

  At the time of storage, the monitor panel 3 is stored by acting in the order of the tilt mechanism unit 6, the monitor panel rotation mechanism unit 5, and the slide mechanism unit 4.

〔effect〕
In the display device of the present embodiment that operates as described above, the monitor panel can be rotated on a plane by the monitor panel rotation mechanism provided between the slide mechanism and the tilt mechanism. As shown in FIG. 2D, the monitor panel rotation mechanism and the tilt mechanism can be operated even when the rear end is left in the casing without completely discharging the monitor panel from the casing. Therefore, the slide amount in the slide mechanism is equivalent to, for example, a wide 7-inch monitor, and a wide 8-inch monitor can be accommodated. As a result, a monitor having a size exceeding 7 inches wide is accommodated as an in-dash-mounted video device. It becomes easy.

  In addition, since the cutouts are provided on the left and right sides of the rear end of the monitor panel, as described above, the end on the back side is placed inside the housing without completely removing the monitor panel from the housing using the slide mechanism. Even if the monitor panel rotation mechanism is left to act, the corner of the monitor panel can be prevented from coming into contact with the housing or the like.
