Description

Roof Mounted Car TV {CAR TELEVISION OF ROOF MOUNTED TYPE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car television, and in particular, mounted on an interior roof of a vehicle to allow the display portion to be automatically rotated during a switching operation and to adjust the angle from side to side, thereby simplifying the user's operation as well as in any position in the vehicle interior. A roof-mounted car television that enables television viewing.

With the development of communication and transportation, there is a rapid increase in the number of people who want to use media such as television and audio in their vehicles.

A car television is a television system installed in a vehicle, and is a device that can view a screen output through a monitor while driving or stopping, and the car television is located in a seat-like and in-dash board installed at the rear of a driver's seat and a passenger seat according to the mounting position. It is divided into an in-dash type to be mounted and a loop type to be installed on an indoor roof of a vehicle.

A typical conventional method of the loop car television is a flip-down type car television 100 that can be folded according to a use state as shown in FIG. 1, which is largely an overhead console. 110 and a display frame 120.

The overhead console 110 is a member installed on the interior roof of the vehicle, the console groove 112 is provided on the back.

The display frame 120 is a screen output portion, one end of which is hinged to the overhead console 110, the display frame 120 to maintain the built-in state in the console groove 112 before use In use, it flips down by user's operation.

Such flip-down type car televisions are described in US Patent No. D413,856 "Overhead console with flip-down television screen for a motor vehicle" and US Patent No. 5,775,762 "Overhead console having flip-down, in addition to the type disclosed in FIG. monitor "and the like.

However, the flip-down car television is not only inconvenient to operate because the flip-down operation of the display frame is performed manually, but also the risk of a traffic accident caused by neglecting the front boundary to flip-down the display frame during driving. There was a problem with this increase.

In addition, the flip-down type car television has a problem in that when the display frame is flipped down suddenly, when the display frame is flipped down, the display frame is rotated upward or flipped up due to inertia, so that the normally displayed screen cannot be viewed. .

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to make the operation of the display portion automatically, the operation process is not only simple, but also a loop that can minimize the risk of traffic accidents To provide a mounted car television.

In addition, another object of the present invention is to provide a roof-mounted car television that can always enjoy a normal screen regardless of the vehicle driving state by maintaining the angle formed by the display portion even if a sudden stop phenomenon or the like occurs during the display operation.

In addition, another object of the present invention is to provide convenience to the user so that the display portion can be viewed from any position in the interior of the vehicle by allowing the left and right angles to be adjusted after the downward rotation and the rotation in the loop mounting state.
