Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle mobile phone device, and more particularly to a structure for mounting a mobile phone body on a rearview mirror.

[0002]

2. Description of the Related Art FIG. 5 is a schematic view of a conventional on-vehicle mobile phone device. In the figure, an antenna 1 is fixed to a trunk lid 3 and connected to a radio main body 7 via a cable 5. The wireless device main body 7 is further connected to the mobile phone main body 11 via another cable 9. Power is the car battery 13
Is supplied to the mobile phone main body 11 and the wireless device main body 7 via the cable 15.

In the above configuration, the mobile phone body 11
The voice signal taken in is converted into a transmission signal by the radio main unit 7 and transmitted from the antenna 1. Further, the received signal taken in from the antenna 1 becomes a voice signal by the radio main body 7 and is converted into voice by the mobile phone main body 11.

[0004]

However, the above configuration has the following two problems.

(1) Since the battery 13 as a power source is on the front side of the car and the antenna 1 is on the rear side of the car,
The length of the cables 9 and 15 is long, and the wiring process of the cables 9 and 15 is difficult. Therefore, the installation work of the in-vehicle mobile phone device is troublesome, and many owners are reluctant to install the car.

(2) Since the long cables 5, 9, 15 are wired so as to crawl inside the vehicle and travel back and forth in the vehicle, the signal transmission loss is large.

The present invention is intended to solve the above-mentioned problems and requires a rearview mirror mounting type in-vehicle mobile phone device which is easy to install, requires only short wiring, and does not take up space for mounting. The purpose is to provide.

[0008]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides an antenna mounted on the outer surface of a windshield, a DC charger for connecting to a battery, a radio signal through the antenna and the windshield.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is an exploded perspective view of the vehicle-mounted mobile phone device of the rear-view mirror mounting type according to the present embodiment as seen from the inside.

An antenna 1 is attached to the outer surface above the windshield. This antenna 1 is a base 1 that is attached to the surface of a windshield 17 with double-sided tape.
9 and an antenna rod 2 extending upward from the base 19
1 and (Fig. 2). The base 19 is the windshield 17
An optical connector (not shown) is provided on the surface contacting with, so that wireless signals can be exchanged through the windshield 17.

A solar cell 23 is attached to the inner surface of the windshield 17. This attachment is performed by a double-sided tape or an adhesive tape that is fixed to the solar cell 23 in advance. The DC charger 25 is also connected to the vehicle battery via a cigarette lighter socket (not shown) or the like.

An antenna box 29 is attached to the inner surface of the windshield 17 near the rear side of the rearview mirror 27 by a double-sided tape or the like. This antenna box 29
Includes an optical connector (not shown) for exchanging wireless signals with the optical connector of the antenna 1, and is also connected to the solar cell 23. Further, it is connected to the DC charger 25 via the curl cord 31 and the connector 33.
By providing both the DC charger 25 and the solar cell 23 in this manner, charging can be performed even on a rainy day, and communication can be performed on a sunny day without exhausting the battery of the vehicle. The antenna box 29 transmits the electric power and the radio signal through the relay board 35 and curls the cord 37.
The curl cord 37 is further connected to the mobile phone main body 11 via the external interface connector 39.

The mobile phone body 11 is held by the holder 43 of the holder device 41. This holder 43 has a rotating shaft 45.
The male screw provided at the tip of is passed through the hole 47 of the holder 43, the hole 51 of the leaf spring 49, and the hole 55 of the adapter 53 and is screwed into the nut 57 to be attached to the adapter 53.
In the leaf spring 49, four recesses 59 are formed around the rotary shaft, and four protrusions 61 are formed on the adapter 53 side in correspondence with the recesses 59. By fitting the protrusion 61 into the concave portion 59, the holder 43 can rotate about the rotation shaft 45 with respect to the adapter 53 at every 90 degrees.

The adapter 53 is provided with four claws 63. The lower two of these claws are movable claws 63a, which are lifted upward by a leaf spring 65 as shown in FIG. 4, and can be attached to the rearview mirror with one touch.

The operation of this embodiment will be described below.
First, the mounting of the on-vehicle mobile phone device will be described. The antenna 1 is attached by attaching the base 19 to the outer surface of the windshield 17 with double-sided tape. The solar cell 23 and the antenna box 29 are also attached with an adhesive tape or a double-sided tape. Antenna 1 and antenna box 2
Since the connection with 9 is made by an optical connector, no wiring is required. In addition, the solar cell 23 and the antenna box 2
An extremely short wiring is sufficient for connection with 9. The sugarlet lighter socket for connecting the DC charger to the battery is near the driver's seat, and thus the windshield 17, and the curl cord 31 does not have to be that long. In addition, this D
Since the C charger 25 may be used on rainy days, it is usually possible to disconnect the connector 31. The mobile phone body 11 is connected to the antenna box 29 by the external interface connector 39. When the upper two claws of the four claws 63 of the adapter 53 are hooked on the upper side of the rearview mirror 27 and the lower two movable claws 63a are pressed against the lower side,
The movable claw 63a once sinks against the force of the leaf spring 65, and then is lifted upward while overcoming the lower side. As a result, the adapter 53 is attached to the rearview mirror 27 with one touch. Then, the holder 43 is attached to the adapter 53 via the leaf spring 49 by the rotating shaft 45. afterwards,
The mobile phone body 11 is held by the holder 43.

When the telephone is used by the apparatus of this embodiment, the holder 43 which is in the horizontal direction is rotated 90 degrees to be in the vertical direction so that it can be easily used.
When the telephone is picked up from the holder 43 and operated by a dial or the like, a voice signal is transmitted through the curl cord 37 to the relay board 35 of the antenna box 29 to be a transmission signal, which is transmitted to the antenna 1 through the windshield 17 and externally. Sent to. On the contrary, the received signal is transmitted from the antenna 1 to the antenna box 29 through the windshield 17, becomes a voice signal, is transmitted to the mobile phone main body 11 through the curl cord 37, and becomes voice. Mobile phone body 1 after use
1 is returned to its original position, and the holder 43 is reversely rotated by 90 degrees so that the holder 43 is turned sideways to secure the field of view of the windshield.

In the above embodiments, a solar cell was provided in addition to the DC charger, but the solar cell is not always necessary. Further, the DC charger may be a normal charger or a quick charger.

As described above, according to this embodiment, the mobile phone body 11 is attached to the rearview mirror 27, and the antenna box 29 is attached to the windshield 17 on the back side of the rearview mirror 27.
Since it is mounted on the inner surface, the device can be mounted in a space on the back side of the rear-view mirror 27 that is not normally used (FIG. 3), and it does not take up much space for mounting the device. The solar cell 23 is attached to the upper part of the windshield 17,
Takes almost no space. Further, since the antenna 1 is attached to the outer surface of the windshield 17, it does not take up any space.
Further, since the holder device 41 has a click function and can rotate the mobile phone main body 11 by 90 degrees, the field of view of the windshield 17 can be kept unobstructed when the phone is not used.

[0022]

As described above, according to the above embodiment, the antenna, the antenna box, and the mobile phone body are attached to the rearview mirror and its vicinity, and the wiring is short,
Therefore, the installation work is simple and the signal transmission frequency is low.
