Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims under 35 U.S.C. § 119(a) the benefit of priority to Korean Patent Application No. 10-2016-0144261, filed on Nov. 1, 2016, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a mounting structure for an image display device disposed in a vehicle.

BACKGROUND

Recently, to enhance the visibility for a vehicle, research on a vehicle including a camera module system provided with a plurality of cameras installed on the outside of the vehicle to enable a driver or a passenger in the vehicle to check outside conditions of the vehicle has been carried out.

Moreover, such a vehicle is provided with a screen for displaying images received from the plurality of cameras on the interior of the vehicle through an optical module. In this regard, development of related devices for assisting in driving of the vehicle and improving convenience in use has become active.

Meanwhile, unlike the configuration of an optical module embedded in a cowl top cover or a dashboard of a vehicle, in the case of a subminiature projection optical module mounted in an A-pillar or B-pillar, there is a problem of low visibility because the size of an image projected onto a screen is small.

Furthermore, with regard to installation of such a subminiature projector, it is not easy to dispose the projector in an interior part of the vehicle and secure a space for configuration of a projection type optical module for projecting an image having a predetermined size sufficient to provide appropriate visibility.

Moreover, in the case of an image display apparatus including a plurality of image modules configured to project images onto a screen, there is a problem in that it is difficult to adjust images projected from two or more image modules.

As a conventional technology, a projection lens unit for a PICO projector is disclosed in Korean Patent Application No. 10-2008-0081806 (hereinafter, referred to as ‘Document 1’). The conventional projection lens unit includes a lens array formed of five sheets, a color synthesizing prism, a cover glass and an image panel.

However, in the case of the configuration of Document 1, it cannot solve a problem of difficulty in installation of an image display apparatus including a subminiature projector. Also, there is still a problem in that, when an image display apparatus including a plurality of image modules is installed, it is difficult to adjust images projected from the respective image modules.

In the following detailed description, names of constituents, which are in the same relationship, are divided into “the first”, “the second”, etc., but the present invention is not necessarily limited to the order in the following description.

The present invention relates to a mounting structure for an image display apparatus which is disposed in an interior trim of a vehicle. The mounting structure for the image display apparatus is configured with a plurality of brackets for adjusting an image to be projected. Furthermore, the mounting structure for the image display apparatus includes a first reflective mirror 500 and a second reflective mirror 600 which are configured such that a projected image is enlarged so as to effectively utilize a confined space in the vehicle. A projection type image display apparatus having an area ranging from 93 cm2 to 100 cm2 may be installed at a position at which the distance between an image module 100 and an image display screen 1000 ranges from 15 mm to 25 mm.

FIG. 1 illustrates the configuration of a mounting structure for an image display apparatus according to an embodiment of the present invention.

As shown in the drawing, the mounting structure for the image display apparatus includes a projection type image module 100. The image module 100 may includes a projection optical system and an illumination optical system. The illumination optical system may include a digital micromirror device (DMD) and be configured such that an image projected from the DMD element is incident on the projection optical system.

The image module 100 may be configured to be disposed on a rotation bracket 400. The rotation bracket 400 may be configured to be sequentially disposed on a mounting bracket 200 and a base bracket 300.

The base bracket 300 is coupled with a base 330 fixed to a vehicle body and functions to fix the image display apparatus and the mounting structure for the image display apparatus.

The base 330 is coupled to an image drive board 700 and a control unit 800 disposed in the vehicle. In addition, the base 330 is coupled to the image module 100 through the base bracket 300.

The image drive board 700 functions to transmit an image to be projected to the image module 100 in response to a signal received by the control unit 800. The control unit 800 may be configured to transmit a command for adjusting the configurations of a plurality of brackets constituting the image display apparatus according to an image adjustment signal of a user.

The rotation bracket 400 is configured so as to be rotatable with a center pin 220 of the mounting bracket 200 as a center axis. The rotation bracket 400 functions to change a direction of projection of the image module 100 fixed and disposed on the rotation bracket 400.

In addition, the rotation bracket 400 is configured such that the first reflective mirror 500 is fixed to a surface of the rotation bracket 400 that faces the image module 100. That is, the first reflective mirror 500 is configured to face the second reflective mirror 600 at a position to which an image is projected from the image module 100.

The first reflective mirror 500 having the above-mentioned configuration makes an image projected from the image module 100 be incident on the second reflective mirror 600. For this, the first reflective mirror 500 is configured to form an angle ranging from 51° to 55° relative to the image module 100 based on the horizontal direction.

An image reflected by the first reflective mirror 500 is projected onto the second reflective mirror 600. The second reflective mirror 600 is configured to re-reflect the projected image and project it onto the image display screen 1000.

The second reflective mirror 600 may be configured to be disposed on a mirror holder formed on a lower surface of the base bracket 300. That is, the second reflective mirror 600 is disposed on the lower surface of the base bracket 300 and configured to face the first reflective mirror 500, and functions to re-reflect an incident image transmitted from the first reflective mirror 500 and project it onto the image display screen 1000.

The mounting bracket 200 is configured such that a guide 320 disposed on an upper end of the base bracket 300 is inserted into a guide boss 210 disposed on the mounting bracket 200. As the guide boss 210 moves along the guide 320, the mounting bracket 200 can move along the guide boss 210. The mounting bracket 200 is configured so as to be movable in a linear direction with respect to the image module 100 fixed on the mounting bracket 200. That is, the mounting bracket 200 to which the image module 100 is fixed can move in a longitudinal direction of the guide boss 210. Accordingly, the distance between the image module 100 and the image display screen 1000 can be changed so that the size of an image to be projected onto the image display screen 1000 can be adjusted. The image module 100 can be moved to the left or the right under the guidance of a guide boss 210 extending in the left-right direction so that the left-right distance of an image displayed on the screen 100 can be adjusted.

The mounting structure for the image display apparatus includes a fastening plate 310 configured to fix the base bracket 300, the mounting bracket 200 and the rotation bracket 400. The fastening plate 310 is configured such that it is fixed to a rear surface of the base bracket 300 and a rear surface of the rotation bracket 400 in a locking form.

More preferably, in an embodiment of the present invention, the fastening plate 310 may be configured to be fixed to the drive board forming the image module 100. The fastening plate 310 functions to fix each bracket of the mounting structure for the image display apparatus.

FIG. 2 illustrates the rotation bracket 400 according to the present invention and shows a radius range within which the rotation bracket 400 can rotate around a center axis.

The rotation bracket 400 according to the present invention is configured to have the same center axis as that of the center pin 220 provided on the upper surface of the base bracket 300 and is configured to be rotatable in a clockwise or counterclockwise direction.

Furthermore, the rotation bracket 400 includes at least one or more rotation guide bosses 410 which are disposed on respective opposite ends of the rotation bracket 400 to determine a turning radius. The rotation bracket 400 is configured to be rotatable along the rotation guide bosses 410.

More preferably, in an embodiment of the present invention, the rotation bracket 400 that is rotatable along the rotation guide bosses 410 is configured to be rotatable by 3.3° in opposite directions so that the projection angle of the image module 100 can move by 3.3° in opposite directions.

As described above, the image module 100 is fixed to the rotation bracket 400. The rotation bracket 400 including the fixed image module 100 is configured such that it can rotate along space formed in the rotation guide bosses 410, thus making it possible to rotate an image projected onto the image display screen 1000.
