[Industrial application fields]
The present invention relates to an in-vehicle display device in which a display unit is pushed out from a main body and the display unit can be rotated after the pushing operation is completed, and an operation in which a channel, a volume, and the like are arranged at a viewing position where the display unit is rotated. The present invention relates to a mechanism for tilting a panel surface to an optimum state for operation during viewing.
[0002]
[Prior art]
In-vehicle display device that attaches the device body to the in-dash part of the car, etc. In order to avoid the weather resistance of the display panel for display, danger from collision when not in use, etc., store the display panel inside the body when not in use There is equipment. When viewing these devices, the display unit portion is pushed out in parallel with the slide base manually or using a motor or the like, and is rotated and turned upright manually or with a motor or the like in a state where the pushing is completed. When the display is stored, the display unit is mounted on the slide base, slides and is stored inside the device.
Conventional control buttons for TV channel selection, volume control, etc., and TV channel display, etc. are on the front of the set when the display unit is housed to simplify the structure, and the display unit is pushed out to the viewing position. Then, it was on the upper surface of the display unit part for rotating. For this reason, the control panel attached to the display unit was usually fixed on the top surface facing upward.
[0003]
[Problems to be solved by the invention]
Therefore, although the control panel is located on the front surface when stored, the display unit is turned upright when viewing, so that the display surface faces the top surface of the display unit. Furthermore, when the display unit is inclined more than vertical, the operation surface portion is facing backward. For this reason, the visibility of the buttons and the liquid crystal display unit arranged when the buttons are operated is poor, and the operability is poor. Furthermore, in order to perform button operations in these states, it is necessary to perform a blind touch or to temporarily turn the screen forward, which is difficult to use.
[0004]
[Means for Solving the Problems]
To achieve the above object, the present invention according to claim 1 is directed to a display unit built in a display device main body, a slide base for sliding the display unit, and the slide base on the slide base in a state where the display unit is pulled out. In the device having the display unit that is pivotably operated, a rotatable operation surface provided on a surface substantially orthogonal to the display surface, and one of which is rotatably attached to the slide base. The other is a display device characterized in that the other is rotatably attached to the operation surface portion, and the operation surface portion is inclined in the forward direction of the device by the operation of the link.
[0005]
[Action]
According to the configuration of the present invention relating to claim 1, when the display panel is rotated and erected, the operation surface portion is erected by the operation of the link, and the operation surface portion is inclined by automatic operation so that the operation buttons and the like are easily recognized.
[0006]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a state in which the display unit 2 is pushed out from the main body 1 for viewing. The display unit 2 is substantially horizontal inside when stored. When viewing, push it in parallel by motor drive etc. (not shown), and manually rotate it upright at the position where the extrusion is completed.
[0007]
FIG. 2 shows a mechanism in which an operation surface portion 3 on which buttons, a display portion and the like are arranged is provided on the upper portion of the display unit 2 and a part is popped out by using a spring so that the panel surface is inclined by pressing an eject button 7.
FIG. 3 shows the internal structure of FIG. The display unit 2 is attached to the slide base 11 so as to be rotatable using a rotation shaft 11a. The operation surface portion 3 is attached to the display unit 2 by fitting the shaft 3a into the hole 2a of the display unit 2 and the shaft 3b into the groove 2c inside the display unit. The rotation spring 10 is attached by inserting each tip between the hole 2b of the display unit 2 and the hole 3c of the operation surface portion. The amount of force of the spring is set in the direction in which the shaft portion 3b moves upward with the rotation shaft 3a as the center. The slide base 4 is fixed to the operation surface unit 3. The slide 5 is attached to the slide base 4 so as to slide in the left-right direction using the pin 4a as a guide.
[0008]
A spring 8 is attached between the hook 4b of the slide base 4 and the hook 5a of the slide, and the slide 5 is attracted so as to move in the right direction. The slide cam plate 6 is fixed to the display unit 2. The slide cam plate 6 has a slot 6a perpendicular to the vertical direction so that the slide pin 5b can pass therethrough. Furthermore, there are horizontal short slots 6b and 6c at the upper and lower ends of the slot, respectively. Therefore, the slot is substantially U-shaped. The eject button 7 is attached to the operation surface portion 3 so as to be rotatable by a rotation shaft 7a. The eject button 7 partially protrudes from the operation surface portion 3, and the protrusion 7b is pushed by hand during the eject operation.
[0009]
In a state where the operation surface portion 3 is pressed from above and the operation surface portion is completely stored in the display unit portion 2, the slide 5 is attracted to the right due to the slide spring 8. At this time, the pin 5b on the slide is engaged by the slide spring 8 at the engaging portion 6b because the slot 6b of the slide cam 6 is substantially horizontal at the lower end. When the button 7b is pressed, the button 7 rotates about the rotation shaft 7a. The button pressing portion 7c moves leftward by the amount of the rotated angle. The button push portion 7c and the slide push portion 5c are in contact with each other when the button is pushed. The slide 5 moves to the left by the amount pressed here. Since the slide 5 has moved, the pin 5b comes off the slot horizontal portion 6d.
[0010]
In this state, the operation surface portion 3 is pushed upward by the spring 10 on the pin 3b side, and the slide pin 5b moves upward because the vertical slot 6a is vertical, and the operation surface portion 3 is centered on the rotation shaft 3a. As a result, the pin 3b side rotates upward. When the operation surface portion 3 rotates and the slide pin 5b hits the upper end slot 6c, the slot 6c is horizontal, so that the slide 5 moves rightward by the attractive force of the spring 8 and enters the slot 6c.
As described above, the operation surface portion 3 is inclined by the angle moved upward in the vertical groove 6a, and is fixed at an inclined position where the key button or the like is easily operated by the engagement between the pin 5b and the horizontal cam portion 6c of the slide cam plate 6. The Even when the operation surface portion 3 is housed, the horizontal cam groove 6b is engaged with the pin 5b, so that the operation surface portion 3 is fixed and has no backlash.
[0011]
FIG. 4 shows a mechanism in which a rising link is provided between the slide base 11 and the operation surface unit 3, and the button / display unit panel is rotated and inclined by the differential operation of the link.
The display unit 2 is rotatably attached to the slide base 11 using a shaft 11a. One of the operation surface portions 3 is attached to the top of the display unit 2 by a rotatable shaft 3a, and the other is attached to the link 12 so as to be rotatable by a rotation shaft 12b. One of the links 12 is attached to the operation surface portion 3 with a rotation shaft 12b, and the other is attached to the slide base 11 with a rotation shaft 12a. One end of the operation surface portion 3 is rotatable about a shaft 3a, and the other end is connected to the link 12 so as to be rotatable by a rotation shaft 12b.
[0012]
The display unit 2 is horizontal when stored, and is horizontal as shown in FIG. 4 when the display unit 2 is pulled out by motor drive (not shown). When the display unit 2 is rotated counterclockwise from the horizontal direction in order to view the slide base 11 with the slide base 11 pulled out, the rotation center axis of the link rotation shaft 12a is the link 12a, and the link rotation shaft 12b. Is the axis 11a. Therefore, the rotation center of the connected screen unit and the operation surface unit 3 is different. For this reason, the link 12 is pushed up because the rotation axis differs with the rotation of the link 12 as shown in FIG. As a result, the operation surface portion 3 connected is rotated at one end and the other end is free, so that the end 12b is pushed up. As a result, the operation surface of the operation surface portion 3 rises obliquely and becomes a position where the key button can be easily operated. In addition, since the operation surface part 3 is always joined by the link 12, it can be configured without play.
【The invention's effect】
According to the present plan, the buttons and the display unit on the operation surface unit are inclined in the direction of the operator with a simple structure, so that the operability and visibility of the operation unit when viewing the display are remarkably improved.
