DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device for a display device which opens and closes a thin display device such as a navigation system of an automobile or a television set for a vehicle between a stored state and a visible state.

[0002]

2. Description of the Related Art Conventionally, in a vehicle such as an automobile, an in-vehicle television device, a navigation system, and the like using a thin display device such as a liquid crystal display device have been used. In addition to the configuration in which the display surface is fixed to a center cluster or the like with the display surface facing the occupant, a configuration in which the thin display device is raised from a center console or the like using a flexible arm or the like is known.

However, in the configuration in which the display surface of the display device is fixed to the center cluster, the display device is generally provided at a low position that does not hinder the field of view.
In addition, since the corners are formed into rounded corners so as not to form corners, the display surface is arranged at a position relatively lower than the line of sight during normal driving, and there is a problem that the amount of movement of the line of sight of the user is increased. doing.

In a support structure using a flexible arm, if the display surface (screen display portion) is held in a state of being exposed inside the vehicle, there is a possibility of deterioration or damage due to direct sunlight or heat. Complicated work of attaching and detaching the flexible arm and the display device is required. Further, a configuration in which the display device is covered with a cover such as a cloth is conceivable. However, such a cover is also troublesome to attach and detach, and has a problem that it takes time and effort to appropriately store the removed cover.

[0005] In this respect, for example, as disclosed in Japanese Patent Application Laid-Open No. Hei 6-16093, a thin display device is stored in a center cluster in a horizontal state, and is used by being pulled out and rotated toward an occupant as needed. The configuration is known. However, in this configuration, the display surface of the display device is provided at a lower position, and is located further on the occupant side than the surface facing the occupant of the center cluster. There is a problem that the burden on the driver to see is large, and the display device may block the air-conditioning air outlet or the operation unit of the air-conditioner.

[0006] As shown in Japanese Patent Application Laid-Open No. H8-9277, a display device is stored in the center of the upper surface of an instrument panel located above a center cluster, and is moved upward, ie, stands up, as necessary. The configuration used is known. In this configuration, in the storage state, the display device is stored substantially horizontally in a recess provided along the upper surface of the instrument panel, with the front display surface facing downward, and That is, the upper side is covered with the lid. In this display device, a first fulcrum located at an upper end portion in an upright state, that is, a passenger side portion (hereinafter referred to as a rear side portion) in a stowed state is pivotally supported by a lid, and a lower end portion in an upright state, that is, a stowed state. The second fulcrum located on the side opposite to the occupant (hereinafter referred to as the front side) is slidably and rotatably supported by a linear guide provided in the concave portion. The lid is rotatably supported on the upper surface of the instrument panel with the front side as a fulcrum, and is driven by a motor. Then, when the motor is driven to open the lid, that is, when the rear side is rotated upward, the display device is configured such that the first fulcrum is lifted upward by the lid and the second fulcrum is moved along the guide. After moving to the rear side, the whole stands up, and the display surface faces the rear side, that is, the occupant side.
On the other hand, when the motor is driven to close the lid, that is, when the rear side is turned downward, the first fulcrum is pushed down by the lid, and the second fulcrum is guided by the force. Along the front side, the whole body falls down, and the display surface faces the lower side and is stored in the concave portion. Further, in this configuration, in order to enable the storage operation of the display device that is pushed and moved by the lid, that is, the second fulcrum pushed downward is slid forward along the guide. As described above, even when the display device is raised up to the maximum, the display surface of the display device forms a depression angle, that is, a state in which the display surface is inclined downward.

[0007]

However, in the configuration described in the above-mentioned Japanese Patent Application Laid-Open No. H8-9277, the storage operation of the display device which is moved by being pushed by the lid is enabled, that is, the display device is moved downward. The display surface of the display device forms a depression angle, that is, tilts downward, even when the display device is fully erected so that the second fulcrum pushed and slid forward along the guide. This causes a problem that it is difficult to improve visibility for a driver having a viewpoint at a position higher than the upper surface of the instrument panel.

A line segment X connecting the support shaft 44 and the second support shaft 46, and a second support shaft 46
The angle .theta. Formed by the tangent to the axis of the axis 46, that is, the tangent Y to the curve of the guide portion 26 passing through the axis of the second support shaft 46 is .theta.x at an arbitrary point between .theta.0 when expanded and .theta.z when stored. Is set to be always in the range of 100 ° to 135 °. For example, in FIG. 1, θ0 is 130 °,
θz is set to 120 ° and θx is set to 110 °.

When the angle θ is set to 100 ° or more, the second support shaft 46 can be smoothly brought into sliding contact with the guide portion 26 during the storing operation. That is, if the angle θ is 90 °, the direction in which the pressing force H is applied is orthogonal to the guide portion 26, and there is no component force in the storage direction J indicated by the arrow J in FIG. No storage operation occurs. And
When the angle θ exceeds 90 °, a component force is generated in the storage direction J, but when the angle θ is set to 100 ° or more, the operation can be performed smoothly.

On the other hand, by further increasing the angle θ, the component force of the pressing force H in the storage direction J further increases, but the operating locus K at the lower end of the display device 11 shown in FIG. As a result, the height of the entire apparatus increases. FIG. 9 is a graph showing this relationship.

Then, as shown in the graph of FIG. 9, when the thickness of the display device 11 is 40 mm, the angle θ reaches about 80 mm, which is twice as large at 135 °, and the practical range considering the layout of the air conditioner and the like is as follows. 135 ° is the upper limit. That is, if the angle is equal to or less than 135 °, not only the storage state of the display device 11 but also the operation locus K requires only a small space below, so that the height of the entire device can be reduced.

In the graph of FIG. 10, the vertical axis represents the height position M of the lowermost point of the operating trajectory K with respect to the lower end portion L on the front side of the display device 11 when unfolded, and the horizontal axis represents the first support. Axis 44
When the second support shaft 46 is displaced rearward with respect to
5 shows the horizontal position (distance) N of the second support shaft 46a from the support shaft 44 to the rear. By adjusting the horizontal position N of the second support shaft 46a according to the graph of FIG. 10, the lower end L on the front side of the display device 11 when unfolded is adjusted.
It can be seen that the height position M of the lowermost point of the operation trajectory K with respect to is adjusted.

As described above, according to the present embodiment, the display unit 14 of the display device 11 can be expanded at an elevation angle toward the occupant, the amount of movement of the line of sight can be reduced, and the visibility can be improved. Sometimes, the height can be reduced by making a depression angle, and the display device 12 can be arranged by effectively using the limited space such as the upper part of the instrument panel 2 without interrupting other devices and the operation unit. The layout of the device can be easily made. Further, in such a support device 12, the curve of the guide portion 26 has a line segment X connecting the first support shaft 44 and the second support shaft 46, which are the vertical support points of the display device 11, that is, the vertical arm 41. And the tangent Y of the curve of the guide portion 26 passing through the axis of the second support shaft 46, the angle .theta. At any point between .theta.0 when expanded and .theta.z when stored is always 100. ° or more, the display device
Since the storage operation of 11 can be performed smoothly and is set at 135 ° or less, the height of the entire apparatus can be reduced.

Further, the curve of the guide portion 26 is at least 100 ° to 135 ° at least in a half portion on the occupant side.
If the following conditions are satisfied, smooth operation is possible, and a single arc can be used, or a combination of curves or straight lines having different curvatures can be used. For example, as shown in FIG. 11, with respect to the center O of the entire length of the guide portion 26, the portion on the occupant side, that is, the rear side, is set such that the angle θ is 100 ° or more and 13 ° or more.
An arc 61 having a radius R1 satisfying the condition of 5 ° or less is connected. An arc 62 having a radius R2 is connected to the front side of the arc 61, and an arc 63 having a radius R3 is connected to the front side of the arc 62.
At the arcs 62 and 63, the angle θ can be set to 135 ° or more.

In the above-described embodiment, the visibility of the display device 11 provided on the instrument panel 2 at a position lower than the line of sight of the occupant is increased by setting the display device 11 to an elevation angle when deployed. For the display device 11 provided at a position higher than the ceiling, that is, the line of sight of the occupant, the above support mechanism is used upside down,
