Abstract

PURPOSE:To eliminate the need for the provision of a feeder by providing a feeding point connecting to an antenna terminal onto a car body near the front ridge of a trunk lid and fitting an antenna provided with a feeder contact member to the front ridge of the trunk lid. CONSTITUTION:A flexible feeding member 18 provided with a contact 17 to the tip is prolonged forward from the base of a pole antenna 15. The contact 17 is connected to the antenna 15 and parted from a rear window glass 10 while the trunk lid 11 is opened as shown in an imaginary line. The contact 17 is brought into contact with the reeding point provided to a prescribed position of the glass 10 attended with the closing of the lid 11. A fixed contact 19 is provided while being exposed to the outer face of the glass 10 in the feeding point. The contact 19 is connected to the antenna terminal of an on- vehicle radio equipment 23 through a lead wire 10 through the glass 10, a connector 21 and a connecting wire 22. Thus, the antenna 15 is coupled with the radio equipment 23 attended with the closing of the lid 11.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mounting structure for a detachable vehicle antenna.

(Prior Art) Conventionally, many pole antennas for car telephones have been removable from the car body in order to prevent theft while the car is parked or breakage caused by drunk people, etc.
In that case, it may be possible to attach the pole antenna to the trunk lint.

As described above, installing an antenna on the trunk lid is also known from Japanese Utility Model Application Publication No. 58-178714, but when the above-mentioned pole antenna is removably attached to the trunk lid, this pole antenna can be attached to the vehicle radio. Because the feeder line for connecting to the aircraft must pass through the trunk, the structure of the antenna mounting part is complicated, and it is not easy to attach or detach the antenna. There was also a problem with the seal around the feeder line.

(Objective of the Invention) Therefore, an object of the present invention is to provide a vehicle antenna mounting structure that facilitates attachment and detachment of an antenna attached to a trunk lid and does not require sealing around a feeder line.

(Structure of the Invention) The present invention provides a power feeding point connected to the antenna terminal of an in-vehicle radio on the vehicle body near the front edge of the trunk lid, and can move toward and away from the power feeding point as the trunk lid opens and closes. An antenna provided with a power feeding contact member is removably attached to the front edge of the trunk lid. When the trunk lid is closed, the contact member comes into contact with the power feeding point, thereby coupling the antenna to the in-vehicle radio.

(Effects of the Invention) According to the present invention, the arrangement of feeder lines from the antenna is no longer necessary, the structure of the antenna mounting portion is simplified, and the appearance is improved. Another advantage is that the antenna can be easily attached and detached.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a perspective view of the rear part of an automobile implementing the present invention,
10 is the rear window glass, 11 is the trunk lid,
12 is a rear damper, 13 is a tail lamp, and 14 is a rear fender. An antenna mounting bracket 16 as shown in FIG. 2 is provided at the base of the pole antenna 15. This mounting bracket 16 is attached to the front edge of the trunk lid 11 with the trunk lid 11 sandwiched between It is removably held. A flexible power feeding member 18 having a contact 17 at its tip extends forward from the base of the pole antenna 15. This contact 17 is electrically connected to the pole antenna 15, and is separated from the rear window glass 10 when the trunk lid 11 is open as shown by the imaginary line in FIG. As the lid 11 is closed, it comes into contact with a power feeding point provided at a predetermined position on the rear window glass IO, as shown in FIG.

A fixed contact 19 is provided at the power feeding point to be exposed on the outer surface of the rear window glass 10.
9 is a lead wire 2 that passes through the rear window glass 10.
0, is connected to an antenna terminal of an on-vehicle radio 23 through a connector 21 and a connection line 22. Therefore, when the contact 17 contacts the fixed contact 19 as the trunk lint 11 is closed, the pole antenna 15 is coupled to the vehicle radio 23.

Next, FIG. 4 shows a case where a fixed electrode 24 is provided on the vehicle side of the rear window glass 10 to form a power feeding point instead of the fixed contact 19 of FIG. 3.

A contact electrode 25 is provided at the tip of the power supply member 18 instead of the contact point 17 shown in FIG.
1 is closed, the contact electrode 25 comes into contact with the power feeding point, and the electrode 24.
The pole antenna 15 is coupled to the in-vehicle radio device 23 by capacitive coupling between the antennas 25 and 25.

Furthermore, FIG. 5 shows a configuration in which electrical coupling at the feeding point is performed by electromagnetic coupling, in which a coil 26 is provided inside the rear window glass lO at the feeding point, and a coil 26 is provided inside the rear window glass lO at the feeding point, and a coil 26 is provided inside the rear window glass lO at the feeding point, and Since the coil 27 is also provided at the contact part at the tip,
The coils 26 and 27 are electromagnetically coupled through the rear window glass 10, so that the pole antenna 15 is coupled to the vehicle radio 23.

The above is the configuration of the embodiment of the present invention. According to such a configuration, there is no need to provide a feeder line for connecting the pole antenna 15 to the vehicle radio 23 through the trunk room, and It is clear that the pole antenna 15 can be attached and detached very easily.
