Description

Vehicle rearview mirror device {SIDE VIEW MIRROR APPARATUS FOR MOTOR VEHICLE}

The present invention relates to a rearview mirror device for a vehicle, and more particularly, to reduce air resistance by reducing the protruding length projecting to the outside of the vehicle and to enlarge the display window of the portable terminal, as well as easy to read information. In addition, the present invention relates to a rearview mirror apparatus for a vehicle that enables hands-free to enhance user convenience.

A general vehicle rearview mirror is a "planar reflector" type having a near plane reflection surface, which is installed outside the vehicle to protrude transversely with respect to the front and rear axis of the vehicle, causing air resistance. Such air resistance not only increases fuel consumption of the vehicle, but also increases the emission of pollutants due to incomplete combustion.

In addition, such a planar reflector type rearview mirror has a relatively small rear and rear projection angle, and in the case of snow or rain, water droplets, moisture, or frost may contact or condense on the surface of the planar reflector, thus making it difficult to rearview. have.

In consideration of such a problem, a rearview mirror for a vehicle employing an optical element has been devised to reduce the protruding length of the vehicle and increase the rear view angle.

Vehicle rearview mirrors that solve the problems of conventional vehicle rearview mirrors employing such optical elements are disclosed in Korean Utility Model Publication No. 76588 and US Pat. No. 5,264,962, respectively, in the name of the present applicant. The Korean patent application No. 99-40282 (1999.9.18) "vehicle rearview mirror" that overcomes the shortcomings has been filed.

On the other hand, with the rapid development of semiconductor technology, the use of portable terminals such as GPS (Global Positioning System Receiver), personal digital assistant (Personal Digital Assistant), including portable telephones is increasing rapidly. The number of subscribers already exceeds the number of fixed-line telephone subscribers.

The portable telephone is provided with a service capable of searching the Internet and providing various necessary information in daily life with location information displayed on a digital map.

Recently, a portable terminal with a built-in web browser is wirelessly connected to a base station, allowing Internet access at a much faster transmission speed than regular telephone lines, and video services including voice, text, and video are available. So-called next-generation video mobile phones that can provide a variety of services, such as interactive TV, have already been developed in Korea.

On the other hand, it is pointed out that the rapid increase in the use of mobile phones and the use of mobile phones while driving increases the incidence of driving accidents. Therefore, in some countries including the United States and Japan, driving to prevent traffic accidents caused by mobile phones has been pointed out. Restrictions on the use of portable telephones are emerging, and in some countries, legislative use of so-called “hands free kits” designed to transmit and receive without picking up portable telephones is being promoted.

However, in the various portable terminals including the conventional portable telephone, the size and the weight are designed in consideration of the convenience of the portable, and when using the hands free kit, the portable terminal is provided through the display window of each portable terminal. As a case of receiving information, for example, a digital map, there is a problem that the size of the display window is relatively small and relatively far from the eye, so that the information displayed on the display window is not easy to read.

Accordingly, an object of the present invention is to reduce the air resistance by reducing the protruding length to the outside of the vehicle and to enlarge the display window of the portable terminal, not only easy to read information, but also hands-free, which is convenient for the user. It is to provide a rearview mirror device for a vehicle that can be improved.
