Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an antenna system for a vehicle and a tuner assembly for the same.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle antenna, and more particularly, to an antenna system for a vehicle in which an installation structure of a tuner connected to an external antenna of a vehicle is improved, and a tuner assembly therefor.

2. Description of the Related Art [0002] With the development of vehicle communication technology in recent years, there has been a growing interest in vehicle antennas for supporting various radio communication services such as DMB, GPS, and mobile communication in vehicles as well as radio frequency signals such as AM / FM.

An automotive antenna is provided in the form of an external antenna to receive signals in the DMB or GPS band. In particular, in recent years, an external antenna having a housing body of substantially a shark fin type is widely used in consideration of air resistance and the like .

The technical literature related to the shark pin type vehicle antenna includes U.S. Patent No. 8,319,693 and Korean Patent No. 1129096.

U.S. Patent No. 8,319,693 discloses a first antenna device disposed outside the vehicle body work 19 and covered by a first cover 15 and a second antenna device disposed inside the bodywork 19 and covered by a second cover 35 And the first antenna device and the second antenna device are mounted on the first carrier plate 3 and the second carrier plate 23, respectively, and are electrically coupled to each other, A vehicle antenna module capable of transmitting to an inside of a vehicle is disclosed. However, the antenna module having such a configuration is expensive because it requires a pair of antennas for each band, and there is a weak point that a receiver for receiving signals of each band must be implemented inside the vehicle.

Korean Patent No. 1129096 discloses a first printed circuit board for receiving signals of AM / FM band in addition to the DMB band, the first printed circuit board being coupled to an upper part of the base and forming a feed line. A second printed circuit board coupled to an upper portion of the first printed circuit board, the second printed circuit board being installed in an upper direction of the case and having a pattern for impedance matching; And a plate-shaped radiator coupled to a pattern for impedance matching of the second printed circuit board and having a folded structure coupled to an upper portion of the case, wherein a conductive coil pattern is formed on the second printed circuit board, And a ground pattern electrically coupled to a ground formed on the first printed circuit board is formed on a lower portion of the second printed circuit board.

The shark pin antenna having the above structure is typically installed outside the roof of the vehicle body. The RF cable drawn out from the antenna is introduced into the vehicle through the rubber molding on the rear glass of the vehicle and then extended to the front portion of the vehicle And connected to the tuner module of the head unit located on the dashboard.

2, the RF cable 20 drawn out from the shark pin antenna 10 is inserted into a gap between the rubber moldings at the top of the rear glass of the vehicle and is wired along the rubber molding to the trunk, And is connected to the terminal unit 30 such as the DMB by wiring to the head unit along the edge molding of the vehicle ceiling.

Therefore, in the conventional shark pin antenna for a vehicle, wiring work is not easy, and an RF cable of a considerable length is required to connect the shark pin antenna with the tuner module, which results in a high cost and a large signal loss rate. In addition, there is a high possibility that a coating is peeled off from a part of the long wiring cable to cause a shot, and measures against this are required.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an antenna system for a vehicle having an improved installation structure of a tuner module for reducing an RF cable length from an external antenna installed outside a loop of a vehicle to a tuner module, The purpose is to provide an assembly.

According to an aspect of the present invention, there is provided an antenna device comprising: an external antenna provided outside a vehicle body; A light transmissive housing provided on a ceiling of the vehicle body, the light transmissive housing having a light transmitting portion on one side thereof, and a lighting mount portion and a tuner mount portion on the inside; An illumination unit mounted on the illumination mount; And a tuner module mounted on the tuner mount and connected to an external antenna installed outside the roof of the vehicle body to provide a frequency tuning function.

Preferably, the external antenna includes a shank pin type antenna housing mounted on the outside of the roof of the vehicle.

The external antenna may include at least one of AM and FM receiving antenna units, a DMB receiving antenna unit, a GNSS receiving antenna unit, and a 2G / 3G / 4G antenna unit.

The external antenna and the tuner module are connected by an RF cable, and the tuner module and the head unit of the vehicle can be connected by a digital wired cable.

The external antenna and the tuner module are connected by an RF cable, and the tuner module and the head unit of the vehicle can be connected by short-range wireless communication.

The RF cable may extend through the vehicle roof to connect the external antenna and the tuner module to each other.

Preferably, the illuminating mount and the tuner mount are spaced apart from each other.

According to another aspect of the present invention, there is provided a portable terminal comprising: a light-transmissive housing installed on a ceiling of a vehicle body, having a light transmitting portion on one surface thereof, And a tuner module mounted on the tuner mount and connected to an external antenna installed outside the roof of the vehicle body to provide a frequency tuning function.

According to the present invention, since the RF cable drawn from the shark pin antenna installed outside the loop of the vehicle can be wired only to the ceiling portion of the loop, the wiring work is convenient, and the manufacturing cost is reduced by greatly reducing the wiring length of the expensive RF cable And the signal loss rate can be lowered.

Further, since the tuner assembly provided by the present invention can utilize the occupying space of the existing room lamp as it is, it has an advantage of not hindering the beauty of the built-in interior.

In addition, when the present invention is applied, the space occupied by the tuner module in the head unit can be removed, thereby improving the space utilization efficiency.
