Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle-mounted antenna device suitable for mounting on a vehicle.

[0002]

[Prior Art]

 When the on-vehicle antenna device is attached to a vehicle, it is generally attached to a rain gutter (rain gutter mounting type) or a trunk (track lid type) of the vehicle.

[0003]

[Problems to be solved by the device]

 However, the rain gutter mounting type cannot be mounted on a vehicle without a rain gutter and may be stolen.

Further, in the case of the trunk lid type, it may not be attached depending on the shape of the trunk, and since it is generally screwed, the vehicle body may be damaged.

An object of the present invention is to provide a vehicle-mounted antenna device in which an antenna main body can be attached at a desired position regardless of the shape of a vehicle body and a vehicle type and theft can be avoided.

[0006]

[Means for Solving the Problems]

 The vehicle-mounted antenna device according to the present invention includes: flexible sheet members 9 and 11 attached to the antenna body 3, and a plurality of permanent magnets 11a arranged and fixed to the flexible sheet members 9 and 11. It is characterized by

[0007]

[Action]

 In the vehicle-mounted antenna device according to the present invention, since the plurality of permanent magnets are arranged and fixed to the flexible sheet member, the flexible sheet member is deformed according to the shape of the mating member, and the permanent sheet is permanently attached. Due to the magnetic force of the magnet, the antenna body can be fixed to the mating member.

[0008]

【Example】

 Hereinafter, a preferred embodiment of a vehicle-mounted antenna device according to the present invention will be described with reference to the drawings.

In FIG. 1, an in-vehicle antenna device 1 has an antenna body 3 and a mounting member 5, and the antenna body 3 has a conventionally known function. It is attached to the vehicle.

As can be understood from FIG. 2, the mounting member 5 is composed of two flexible sheet-shaped members 9 and 11, and each sheet-shaped member 9 and 11 is, for example, an elastic member. It is made of plastic that has properties.

In addition, a plurality of permanent magnets 11 a are arranged and fixed to the sheet-shaped member 11 in a lattice pattern at desired intervals, while the sheet-shaped member 9 has the permanent magnets 11 a. The holes 9a to be fitted in each are formed in a grid pattern.

The two sheet-shaped members 9 and 11 are attached and integrated with each other with an adhesive 10.

Here, the antenna main body 3 is provided with two columnar leg portions 7 each having a circular flange portion 7A, and a thread groove (screw portion) is provided at a projecting end portion of the leg portions 7. Has been formed.

The sheet-like member 9 is formed with a through hole 9A into which the threaded portion of the leg portion 7 is inserted and a circular recess 9B in which the washer 13 is housed.

On the other hand, since the sheet-like member 11 is formed with the through hole 11A for inserting the washer 13 up to the recess 9B, the leg portion 7 is inserted into the through hole 9A and the protruding end portion thereof is inserted. When the nut 15 is screwed into the threaded portion, the washer 13 and the flange portion 7A sandwich the sheet-shaped member 9, whereby the mounting member 5 is integrated with the antenna body 3.

In the antenna device 1 configured as described above, as can be understood from FIG. 3, the mounting member 5 can be bent (deformed) with the length L of the leg portion 7 being the maximum.

Therefore, as can be understood from FIG. 4, when the antenna device 1 is mounted at a desired position such as the roof of the vehicle 100, the windshield, the trunk, etc., the mounting member corresponds to the shape of the vehicle body at that position. 5 deforms and comes into close contact, and is fixed by the magnetic force of the permanent magnet 11a.

When the antenna device 1 is attached to the front windshield, for example, a double-sided adhesive type magnetic tape may be attached to the glass so that the magnetic tape is attracted by the permanent magnet 11a.

As described above, in this embodiment, the antenna main body 3 is mounted on the vehicle 100 by the mounting member 5 which is flexible and has the permanent magnet 11a arranged and fixed thereto. The antenna device 1 can be attached at a desired position regardless of the vehicle type (passenger car, truck, etc.).

Further, since it is attached by magnetic force, it is possible to avoid theft because the vehicle body is not damaged and can be easily removed during parking, for example.

[0021]

[Effect of the device]

 As can be understood from the above description, in the vehicle-mounted antenna device according to the present invention, since the plurality of permanent magnets are arranged and fixed to the flexible sheet member, the flexible sheet member can be formed according to the shape of the mating member. The flexible sheet member is deformed, and the magnetic force of the permanent magnet allows the antenna body to be fixed to the mating member.

Therefore, since the fixed position of the antenna body can be set to a desired position of the vehicle body, the antenna body can be attached regardless of the shape of the vehicle body or the vehicle type.

Further, the vehicle body is not damaged as in the case of screwing and can be removed during parking, for example, so that theft can be avoided.
