Description

MOTORIZED OPENING/CLOSING DEVICE OF MONITOR FOR AUTOMOBILES}

The present invention relates to an electric opening and closing device for an automobile monitor. More specifically, an automobile monitor that stably supports the monitor to prevent sagging and adjusts the opening angle to the maximum so that the occupant can view the monitor screen in the desired position. It relates to electric switchgear.

In general, cars are very closely related to real life in daily life, and recently, they have moved beyond the concept of a simple means of transportation and are beginning to be recognized as a personal, independent living space.

In addition, in recent years, the driving performance and ride comfort of vehicles have been improved, as well as the installation of various convenience devices for vehicle occupants has been increasing day by day. Until now, this was mainly applicable to luxury sedans, but recently, even semi-mid-sized or mid-sized vehicles are installed. The scope is expanding.

In particular, with the increase in the number of car users, the time spent in the car is increasing, and with the advent of the information age, passengers in the back seat can watch TV and movies through the car's navigation system or a separate rear monitor. Recently, LED monitors have been installed. , Going beyond the concept of a monitor for simply viewing using an LCD panel, it is gradually transforming into a multimedia type equipped with various functions such as the Internet, information search, games, as well as watching various videos, photos, and TV.

Meanwhile, monitors installed in vehicles are usually installed on the dashboard or headrest, or a separate installation bracket is fixed between the driver's seat and the passenger seat and the monitor is generally used in combination with this.

That is, as shown in FIG. 1, the monitor fixing device for installing the monitor on the ceiling of the vehicle is installed so that the main housing 20, which allows the monitor 10 to be tilted, is fixed to the ceiling wall at any position on the interior ceiling of the vehicle. Then, the monitor (10) can be unfolded using a tilting motion to watch, and when not in use, the monitor (10) can be folded in a reverse motion.

However, in the case of a conventional automobile indoor monitor, when an impact occurs during driving due to the weight of the monitor, the folded monitor unfolds strongly without the occupant tilting it, resulting in device failure and tilting operation without warning, causing damage to the occupant's head or body. There is a risk of a safety accident due to the monitor colliding with the monitor.

In addition, passengers must adjust the angle of the monitor to view it clearly, but conventional monitors mounted inside the vehicle are often fixed inside the vehicle without adjusting the angle, and even if they can be adjusted, they have a very limited range (up to 90 degrees). ), there is a drawback in that by adjusting the angle of the monitor, only a certain viewing direction is provided to the occupants and it does not sufficiently satisfy the occupants' needs for more convenient viewing.

Therefore, the present invention was created to solve the above-mentioned problems. The purpose is to stably support the monitor without tilting even under the weight of the monitor and external shocks, and to provide comfortable comfort desired by the passenger by expanding the tilting angle of the monitor to about 165 degrees. The aim is to provide an electric opening and closing device for an automobile monitor that can be viewed from one's posture.

In order to achieve the above object, an electric opening and closing device for a monitor for a car according to an embodiment of the present invention includes a body fixed to the interior of a vehicle, a rotating plate provided inside the body, the rotating plate and the body connected to the rotating plate. A monitor angle adjusting unit that is guided inside the body according to rotation to adjust the angle of the monitor, a driving unit provided in the body to rotate the rotating plate, and electrically connected to the driving unit to drive the driving unit. It may include a control unit that controls.

The body portion may include an upper frame fixed to the vehicle interior, a lower frame connected to the lower part of the upper frame, and a connection frame provided between the upper frame and the lower frame to connect the monitor angle adjustment unit and the driving unit. there is.

Guide grooves may be formed on both sides of the connection frame in the longitudinal direction so that the monitor angle adjustment part can be guided forward and backward.

Limit switches may be provided before and after the upper part of the connection frame to output the closed position and the maximum unfolded position so that the monitor is in close contact with the lower part of the connection frame.

A gear damper may be installed in the connection frame so that the drive unit can be driven at a constant speed without being affected by the load when rotating by engaging the teeth of the rotating plate.

The rotating plate is provided on the upper part of the connecting frame and is rotatably connected by a hinge. A plurality of the rotating plates are symmetrically in contact with each other and may be formed with teeth engaged on the sides so that they can rotate together when the driving unit is driven.
