BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display panel locking mechanism, and more particularly, to a display panel locking mechanism capable of smoothly changing the angle of a display panel.

[0002]

2. Description of the Related Art In recent years, an automobile has often been equipped with a display for receiving a television image or displaying navigation information. In addition, in order to widely use the cabin, a flat display panel using liquid crystal, which can be stored in the dashboard provided between the driver's seat and the passenger's seat when not in use, is generally applied. It is.

FIG. 6 is a bird's-eye view of the cabin of an automobile.
When receiving a television or displaying navigation information, the key switch 1
When the user operates the tray 2, the tray 13 is sent out of the housing 11. When the feeding of the tray 13 is completed, the display panel 14 rises from the tray 13 and the display can be performed.

However, since the housing 11 may be installed on a curved dashboard, it is necessary to adjust the angle of the display panel 14 in a used state within a certain range. For this purpose, a fan-shaped cam having a plurality of recesses is attached to the rotating shaft of the display panel 14, and the recesses are fitted with a lock lever to fix the angle of the display panel.

[0005]

However, since the conventional lock pin is a round bar-shaped member, in order to increase the angle fixing force, the recess provided in the cam is made deeper or the force for bringing the lock lever into contact with the cam is made stronger. However, if the depression is deepened or the contact force is increased, a large force is required to adjust the angle of the display.

Conversely, if the recess is made shallow or the contact force is weakened to facilitate the adjustment of the display angle,
There was a possibility that the angle fixing force was weakened and the angle was changed by running vibration. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a display panel lock mechanism that secures an appropriate angle fixing force and facilitates angle adjustment.

[0007]

SUMMARY OF THE INVENTION A display panel locking mechanism according to the present invention is provided in common with a tray, a display panel stored in the tray when not in use and raised from the tray when in use, and a rotation axis of the display panel. And a display panel comprising: a fan-shaped cam that rotates with a display panel having at least two recesses formed around the fan-shaped cam; and a lock pin that fits into one of the at least two recesses formed in the fan-shaped cam. In the lock mechanism of (1), a roller is provided so as to be rotatable around a lock pin.

[0008]

In the lock mechanism of the display panel according to the present invention, when the roller rotating around the lock pin moves while rotating in the recess provided in the fan-shaped cam, the recess is made deeper or the roller is rotated. Even when the contact force with the cam is increased, the angle of the display panel can be easily adjusted.

[0009]

FIG. 1 is a perspective view of a display according to the present invention, in which a housing 11 is mounted on a dashboard of an automobile. 2 and 3 are explanatory diagrams of the operation of the display, and a series of operations proceeds in numerical order.

When not in use, the tray 13 is stored in the housing 11 (state 1). When the key switch 12 provided on the front surface of the housing 11 is pressed, the tray 13 is pulled out by a motor (not shown) driven (state 2). When the tray 13 is completely pulled out, the display panel 14 is raised up to about 60 degrees by the spring force (state 3).

[0011] Further, the display panel 14 is raised to approximately 90 degrees by the occupant (state 4). Next, the tray 13 is retracted by a predetermined distance, and the display is activated (state 5). When use is completed, the housing 11
When the key switch 12 provided on the front of the tray is pressed, the tray 13 is pulled out forward again (state 6).

Next, the passenger stores the display panel 14 in the tray 13 (state 7). Then, the tray 13 is stored in the housing 11 by driving the motor (state 8). That is, the operation proceeds as a series of operations up to the state 4, but the operation for causing the display panel 14 to be substantially 90 degrees must be performed by the occupant, and must be securely fixed at an easy-to-view angle.

FIG. 4 is a side sectional view, showing the display panel 1 coaxially with the rotation axis 141 of the display panel 14.
4 and a cam 142 fixed thereto. The solid-line display panel 14 indicates a state of being stored in the tray 13, and the broken-line display panel 14 indicates a state of rising from the tray 13. The cam 142 is provided with three recesses 143, 144, and 145 on the outer periphery.
The display panel 14 is set at 75 degrees, 90 degrees and 105 degrees.
It is possible to adjust to three levels of degrees.

FIG. 5 is a partial perspective view of the inside of the tray 13 and shows a mounting structure of a lock pin and a roller that are fitted into three recesses 143, 144, and 145. That is, the lever 1 is rotatable around the shaft 131 inside the tray 13.
32 is attached, and a lock pin 133 is attached to the tip of the lever 132. Lock pin 133
A roller 134 is rotatably fitted around the lock pin 133.

An elliptical hole 135 is formed in the member 132, and a pin 1 fixed inside the tray 13 is formed.
36 and regulates the moving range of the member 132.
A winding spring 137 is attached to the shaft 131 together with the member 132, and urges the member 132 so that the roller 134 contacts the outer periphery of the cam 142. Shaft 13
1, E-ring 1 on pin 136 and lock pin 133
51, 152 and 153 are fitted, and lever 1
32 or the roller 134 is prevented from falling off.

Accordingly, the roller 134 is provided with the concave 1 of the cam 142.
43, 144 and 145, the display panel 14 can be smoothly moved even when the depth of the recess is increased or the fixing force of the display panel 14 is increased by increasing the urging force of the winding spring 137. 14 can be changed.

[0017]

According to the lock mechanism for the display panel of the present invention, the angle of the display panel can be smoothly adjusted even when the fixing force of the angle of the display panel is large.
