Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mount for a wireless communication antenna that is attached to the edge of a trunk lid of an automobile.

In general, most wireless communication antennas that are attached to the trunk lid of a car use a whip-type metal wire due to the frequency, and the length does not need to be extremely short. There is. However, as frequencies become higher, such as in car telephones, the length of whip-type antennas becomes extremely short, so there is no problem when installing them on the roof or on the gutter on the roof side. However, when it is attached to the trunk lid, which is easy to attach, it is easily affected by the roof of the car. For this reason, sleeve-type antennas are often used in relation to the grounding board in order to position the antenna element at a high position.

Incidentally, the angle adjustment structure conventionally generally employed for mounting on an inclined surface is applied to whip-type antennas. A typical example of this is shown in the specification of Japanese Utility Model Application Publication No. 53-62245, in which the angle can be adjusted in all directions by a combination of bending and rotation of the element near its base. It is something. In this way, when the element part is provided with a structure that allows the angle to be varied, the antenna element is made so as not to be separated from its mounting mount. The reason for this is that when using a connector type, when screwing in, the antenna element at a certain angle draws a circle corresponding to that angle, and in some cases, it may hit something and not be able to screw in. This is due to the fact that it does not always face in a certain direction depending on the state of the object. However, if the antenna element is formed integrally with the mounting mount, it is not only difficult to attach and detach it easily when washing the car, but also if the mounting surface is tilted differently.
The disadvantage is that the direction of the antenna element cannot be easily adjusted to accommodate this.

The purpose of the present invention is to eliminate such drawbacks by using a connector type antenna element that can be easily attached and detached, as well as easily adjusting the orientation of the antenna element to adapt to mounting surfaces of different slopes.
An object of the present invention is to provide an automobile antenna mount that can stably maintain its state.

According to the present invention, a cylindrical circular mount having a flange bent toward the center on the periphery of the top;
a circular lid having an antenna connector attached at an angle in the center thereof, narrowing the flange of the circular table mount and placing the circular lid on the upper surface of the flange;
A disc-shaped screw holder is made to correspond to the inner surface of the flange, and the circular lid is fixed to the flange of the circular table mount by tightening the screw from the circular lid to the screw holder. A possible automotive antenna mount is obtained.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an exploded, partially cutaway perspective view of the components of an embodiment of the present invention, and FIG. 2 is a side view showing the installed state after assembly. As shown in the figure, this antenna mount consists of a mounting bracket 2 with one side bent into a U-shape so that it can be fitted into the end of the trunk lid 1 of an automobile.
A cylindrical mount 3 having a flange 4 bent toward the center at the top periphery is fixed by screws to the top of the cylindrical mount 3, and an antenna connector 8 is installed at an angle on the flange 4 of the cylindrical mount 3. Place the circular lid 9 with the circular lid 9 on the inner surface 4a of the flange 4, align the disc-shaped screw holder 5 with the inner surface 4a of the flange 4, and tighten the screw 6 and washer 7 from the circular lid 9 to the screw holder 5 to make the circular lid 9 circular. Flange 4 of pedestal mount 3
It is fixed to Then, the inner surface 4a of the flange 4 of the round table mount 3 and the disk-shaped screw receiving fitting 5
The upper surface 5a is provided with projections and depressions that engage with each other during tightening.

According to this structure, in order to match the installation location to the trunk lid of a car or the difference in inclination depending on the car model, after inserting the antenna element to be installed on the trunk lid into the connector, the screw 6 is loosened. The angle can be easily adjusted by turning the circular lid 9 as shown by the arrow. Then, after tightening screw 6 after adjustment,
The angular position is always maintained constant regardless of whether the antenna is attached or detached, and the unevenness of the flange surface meshes with each other, so rotational deviation does not occur even when the antenna element is attached or detached due to external forces or vibrations caused by driving. .

In the above embodiment, the angle of inclination of the connector from the vertical direction varies depending on the vehicle type and its installation location, but the angles α and β from the horizontal of the end of the trunk lid shown in Fig. 3 are generally around 10°. It seems that there are many. Therefore, it is sufficient if the angle can be adjusted to this extent; it is not preferable to make the angle too large as this will deteriorate the characteristics of the antenna.

As is clear from the above explanation, according to the present invention, it is possible to stably fix the circular cover having the antenna connector inclined with respect to the circular table mount in any direction, and thereby, the antenna Since the element can be attached and detached as necessary, and the orientation of the antenna element can be easily and safely adjusted even if the inclination of the mounting surface is different, great effects can be obtained in terms of use and handling.
