BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for a monitor mainly provided in a cab of a construction machine such as a hydraulic shovel or a working vehicle.

[0002]

2. Description of the Related Art FIG. 4 is a perspective view showing the inside of a cab 1 for a hydraulic excavator (not shown). In the figure,
2 is a cab of the cab 1, 3 is a floor plate, 4 is a driver's seat, 5L and 5R are left and right working operation levers, 6L and 6R are control boxes respectively, 7L and 7R are left and right pedal running levers, and 8 is an operation lever. The panel 9 is a display. 2. Description of the Related Art Conventionally, a display 9 having a display unit for monitoring is attached to the front of an operation panel 8 on the side of a driver's seat (4) in a cab 1.

[0003]

As a prior art display device, as shown in FIG. 4, a display device is disposed in front of a control panel on a driver's seat side. As a result, the driver's operating hand gets in the way, making it difficult to see the display unit of the display unit, making it difficult to confirm the display. In addition, since the driver must take an unusual driving posture when looking at the display, it cannot be said that safety is perfect. The present invention
An object of the present invention is to provide a display device of a construction machine that can solve the above-described problems.

[0004]

A display device according to the present invention has a display device having a display unit for a monitor or the like.
A display device in which the display device is provided in a cab such that the display device can be tilted and adjusted, wherein the display device is disposed at an inner corner portion where a front panel and a side panel for obtaining a front view and a side view of a cab for a cab contact. And, the display unit of the display unit is rotatable so that the display unit is close to the side panel, and the display unit can be stored along the side panel so that at least the front view is not obstructed. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of a main part showing the inside of a cab 1a having a display device according to a first embodiment of the present invention. In the figure, the same reference numerals are given to components using the same components as the conventional technology. 2a is a cab of the cab 1a, 8 'is an operation panel, 10 is a display, 11 is a harness connected to the display 10, 12 is a front panel of the cab 2a, and 13 is a side panel. FIG. 2 is a detailed view of a portion A in FIG.
In the figure, 14 is a hinge member which hinges the display 10 on the inner surface of the cab 2a, and 15 is a display section of the display 10.

Next, the structure of the display device according to the first embodiment of the present invention will be described with reference to FIGS. In the display device of the first embodiment, the cab 2a is attached via a hinge member 14 to an inner corner portion (position indicated by reference numeral A) where the front panel 12 and the side panel 13 are in contact with each other. It was configured to be able to be rotated and stored so as not to be turned. Note that the rotating means is not limited to manual operation, and power may be used.

Next, the operation of the display device according to the first embodiment of the present invention will be described. As shown in FIG. 1, the display 10 is provided at an inner corner where the front panel 12 and the side panel 13 are in contact with each other.
(Including lower front view) and side view. Further, since the driver can see the display 10 substantially obliquely in front, it is not necessary to take an unusual and unnatural driving posture. Further, since the display 10 is hinged to the cab 2a by the hinge member 14, the display 10 can be rotated and adjusted to a desired angle by the driver according to, for example, the state of irradiation of sunlight. When the display 10 is not used, the display device 10 rotates about the axis of the hinge member 14 in the direction of arrow B, so that it does not interfere with the inner side of the side panel 13 (a portion indicated by a virtual line C in FIG. 2). Can be stored.

Next, FIG. 3 is a plan view of a main part showing the inside of a cab 1b provided with a display device according to a second embodiment of the present invention.
In the figure, the same components as those in the display device of the first embodiment are denoted by the same reference numerals. 2b is cab 1
b, cab 12 'is the front panel of cab 2b, 13'
Is a side panel, 16 is a display, and 17 is a spherical joint (ball joint) that supports the display 16 on the inner surface of the cab 2b.

Next, the structure of a display device according to a second embodiment of the present invention will be described with reference to FIG. In the display device according to the second embodiment, a spherical joint 17 is provided at an inner corner portion (position indicated by reference numeral a ') where the front panel 12' and the side panel 13 'of the cab 2b are in contact.
And can be rotatably stored on the inner side of the side panel 13 'so as not to interfere when the display 16 is not used. Although the display device of the second embodiment uses the spherical joint 17, a universal joint (not shown) or the like may be used instead of the spherical joint. The operation and function of the display device of the second embodiment are the same as those of the display device of the first embodiment.

[0010]

In the display device of the prior art construction machine, the display device is arranged in front of the operation panel on the side of the driver's seat. As a result, the driver's operating hand gets in the way, making it difficult to see the display unit of the display unit, making it difficult to confirm the display. In addition, since the driver must take an unusual driving posture when looking at the display, it cannot be said that safety is perfect. However, in the display device of the present invention, the display is disposed at the inner corner where the front panel and the side panel of the cab for the driver touch each other, and the display is configured to be rotatable. That is, in the present invention, since the display is provided at the inner corner portion where the front panel and the side panel are in contact, the display does not obstruct the front view and the side view. In addition, the driver can view the display substantially obliquely from the front, so that the driver can check the display unit of the display without taking an unreasonable and unnatural driving posture, thereby ensuring safety. Also, when not using the display, it can be turned and stored on the inner side of the side panel so as not to interfere.
Convenience and comfort are improved, and the beauty of the cab can be enhanced.
