Description

[Detailed description of the invention] This invention is an antenna that is attached to the body of a car so that it can be raised and lowered, and more specifically, a so-called pillar-retractable antenna that is housed in the internal space of a pillar and protrudes from the pillar to the outside of the car body when in use. It's about structure.

As this kind of antenna device, for example,
The one proposed in Publication No. 138 is publicly known.

In recent years, the above-mentioned pillar-retractable antenna has been used as an antenna device for automobiles, and has the following advantages: the driver can manually raise and lower the antenna, the antenna is hidden when not in use, giving it a good appearance, and there is no problem with wind noise. are widely adopted.

This type of antenna is attached to the outer panel of the vehicle body by diagonally penetrating the outer panel of the vehicle body that forms a pillar together with the inner panel of the vehicle. Three parts are used: an integral cover for fixing the tube body to the outer panel of the vehicle body, and a base body for sealing between the integral cover and the outer panel of the vehicle body.

It is desirable for these three parts to be assembled in advance before being attached to the outer skin of the vehicle in terms of installation workability, and since the cover itself has a relatively long and slender shape, it is difficult to seal it with the base body. Since it is easy to be sure,
It is desirable to have good sealing properties.

In view of the above-mentioned problems of the prior art, this invention was developed to provide a base body interposed between the vehicle body outer plate and a cover body that fits and holds a tube body that holds the antenna so that it can be inserted freely. By providing a band portion that engages with the tube body, the above-mentioned tube body for attaching the antenna, the cover unit, and the base body can be assembled in advance as an assembly. The object of the present invention is to provide a mounting structure for an automobile antenna with excellent sealing properties.

Embodiments of this invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes an antenna device that is attached to an outer panel 2 of an automobile body so as to be able to rise and fall freely, and this antenna device 1 includes:
It consists of an antenna rod 3 and an antenna cable 4 that connects the antenna rod 3 to a radio.

5, the antenna rod 3 is attached to a front pillar part 2a of the vehicle body outer panel 2 together with a cover integral 6 and a base body 7, which will be described later.
It is a tube body for installation through the.

The tube body 5 is formed of a tube member made of an insulating material and holds the antenna rod 3 so as to be inserted therethrough, and is inside the front pillar 2a formed by the vehicle body outer plate 2 and inner plate (not shown). It is installed in the space S, and its upper end extends obliquely through a long hole 2b opened in the front pillar 2a and projects outward from the vehicle body.

Reference numeral 6 designates the aforementioned integrated cover that is fixed to the front pillar 2a with screws 6a, and this integrated cover 6 is connected to the elongated hole 2.
The tube body 5 is fitted and held by the upper wall 6b of the tube body 6, which is elongated and has a substantially triangular cross section that can hide the tube body 6b.

On the other hand, 7 is the aforementioned base body made of an elastic material, which is interposed between the cover unit 6 and the front pillar 2a and seals therebetween.

This base body 7 has a long hole 7a that penetrates the tube body 5 obliquely like the long hole 2b, and a tube body 5 that protrudes outward from the vehicle body approximately in the center of the long hole 7a and passes through the long hole 7a.
An integrally molded band portion 7b that engages with is provided.

Note that 8 is a grounding fitting that connects the shield layer of the antenna cable 4 to the cover unit 6 and grounds it to the vehicle body via a screw 6a.

Next, the operation of the automobile antenna mounting device constructed as described above will be explained.

The antenna device 1 connects the tube body 5 to the front pillar 2 through the long hole 2b of the front pillar 2a from outside the vehicle body.
The antenna rod 3 is installed in the interior space S of the vehicle body S, and its upper end is fixed to the front pillar 2a through the cover unit 6, so that it can be attached to the vehicle body outer panel 2, and the antenna rod 3 can be manually operated to protrude outward from the vehicle body. However, before this installation work, the tube body 5 and the cover unit 6 can be temporarily fixed by fitting and holding them, and the tube body 5 and the base body 7 can be temporarily fixed by engaging the band portion 7b. Since these three parts, the tube body 5, the cover body 6, and the base body 7, can be assembled in advance, the above-mentioned installation work can be done by attaching the assembly body to the front with the screws 6a. The work of fixing it to the pillar 2a is all that is required, and the work efficiency can be greatly improved.

On the other hand, during the above-mentioned installation work, the opening portion of the elongated hole 7a of the base body 7 tends to deform laterally due to the tightening force of the screw 6a.
This deformation is prevented by the band portion 7b being locked to the side wall of the cover unit 5, and the sealing performance of the base body 7 is not deteriorated, and the gap between the cover unit 6 and the front pillar 2a is reliably sealed. be able to.

In this way, the hand portion 7b provided on the base body 7 acts, and if we assume that the band portion 7b is not provided,
If the screw 6a is used to assemble the above three parts into an assembly, the contact surface to the car body outer plate 2 will not be completely covered with the elastic material as in the above embodiment, and the tip of the screw 6a will be painted during the installation process. It is expected that problems such as peeling of the surface or deformation of the base body 7 due to the tightening force of the screws 6a and deterioration of its sealing performance may occur. The effect is tremendous because it prevents

In addition to the above effects, the band portion 7b also has the advantage that the tube body 5
It also has the effect of preventing the vibration from coming into contact with the cover unit 6 and generating abnormal noise.

In addition, in the above embodiment, the antenna device 1 is connected to the front pillar 2.
Although this was an example in which the pillar was attached to a pillar, this idea can also be applied to the case where it is mounted to other pillars.

As explained above, according to this invention, a tube body that passes through the base body is attached to a base body that is interposed between the cover unit that fits and holds the tube body that holds the antenna so that it can be inserted freely, and the outer panel of the vehicle body. By providing a band portion that engages with the tube body, the three parts, the tube body, the cover body, and the base body, can be assembled into an assembly body that can be assembled in advance, improving the installation workability and preventing deformation of the base body during the installation work. This makes it possible to prevent this and ensure the seal, thereby providing an excellent mounting structure for an automobile antenna that satisfies all of the above-mentioned problems.

Note that since the band portion can be formed integrally with the base body, the number of parts will not increase.
