Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile antenna mounting device for insulating engine noise and the like propagating in a pillar by using a housing for an antenna such as a radio.

[0002]

2. Description of the Related Art Conventionally, in order to prevent the engine sound from being transmitted to the vehicle interior through the inside of the front pillar, and to prevent the wind noise during traveling from being transmitted to the vehicle interior,
As shown in FIG. 7, the pillar 1 is provided inside the front pillar 1.
The sound-absorbing plate 2 having the same size as the cross-sectional shape of the above is inserted so as to insulate the sound.
No. 231).

Further, since the radio antenna 3 as shown in FIG. 8 is inserted into the pillar 1, a cutout hole 4 for inserting the antenna 3 is formed substantially in the center of the sound absorbing plate 2. ing.

Front pillar 1 for automobiles (especially passenger cars)
As shown in FIG. 8, the antenna 3 attached to the antenna is housed in the antenna housing cylinder 5.
The antenna cord 6 is clipped to the clip 7 and inserted into the inside of the front pillar 1. The terminal of the cord 6 of the antenna 3 thus mounted is pulled into the room and connected to the radio terminal.

In FIG. 8, reference numeral 8 indicates an antenna hole provided in the front pillar 1, and reference numeral 9 indicates an antenna hole cover made of synthetic resin attached to the upper end of the antenna housing cylinder 5.

[0006]

In the prior art described above, when the antenna or the antenna cord is inserted into the inside of the front pillar, these must be passed through the cut holes of the sound absorbing plate provided inside the front pillar. However, the insertion work was complicated and the workability was very poor. further,
When the vehicle is assembled, the workability is further deteriorated because the operator cannot reach inside the front pillar.

The present invention has been made to solve the above-mentioned conventional problems. A flange member orthogonal to the axis of the antenna housing cylinder is provided in the antenna housing cylinder, and the antenna cord is held by this flange member. It is an object of the present invention to provide an antenna mounting device for a vehicle, in which engine sound and wind noise are reduced by inserting the antenna into the front pillar and the workability thereof is improved.

[0008]

According to a first aspect of the present invention, an antenna housing cylinder is inserted into a front pillar formed by joining a plurality of panels into a cylindrical shape, and the antenna housing cylinder is rod-shaped. In an automobile antenna mounting device in which an antenna is inserted, an elastic sheet flange member is mounted on the outer periphery of the antenna housing cylinder.

The invention according to claim 2 is characterized in that a plurality of flange members of the elastic sheet are attached to the outer periphery of the antenna housing cylinder at intervals.

Furthermore, the invention according to claim 3 is characterized in that the shape of the flange member of the elastic sheet is similar to the cross-sectional shape of the front pillar, and the area thereof is slightly larger than the internal area of the front pillar. It is what

[0011]

According to the invention described in claim 1, since the flange member of the elastic sheet blocks the inside of the front pillar, the propagation of various noises is reduced, and at the same time, the noise generated when the antenna housing cylinder touches the inner wall of the front pillar is generated. Can also be prevented. Also, the antenna cord can be held in the antenna housing cylinder by the flange member.

Further, according to the second aspect of the invention, since a plurality of flange members of the elastic sheet are attached to the outer circumference of the antenna housing cylinder, it is possible to more effectively reduce the propagation of various noises. .

Further, according to the third aspect of the invention, since the flange member of the elastic sheet can be brought into close contact with the inner wall of the front pillar, it is possible to reduce the propagation of various noises.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. 1 with the same members as those in FIGS. FIG. 1 shows the antenna 3 of the automobile 10 shown in FIG. 3 inserted into the front pillar 1.

As shown in FIG. 4, the front pillar 1 is formed by joining a plurality of panels, that is, a roof front rail 11, a side body outer 12 and a roof side inner rail 13 into a tubular shape.

The antenna 3 is housed in the antenna housing 5 so that it can be extended to the outside when desired. On the outer circumference of the antenna housing cylinder 5 and the outer circumference of the antenna cord 6 provided along the antenna housing cylinder 5, an elastic sheet having a similar shape to the cross-sectional shape of the front pillar 1 as shown in FIG. The flange member 14 of the seat is attached orthogonally to the axis of the antenna housing cylinder 5.

Two flange members 14 are provided on the outer circumference of the antenna housing cylinder 5 and the antenna cord 6 with a space therebetween. The flange member 14 is attached to the antenna housing cylinder 5 by inserting the antenna housing cylinder 5 and the antenna cord 6 into an insertion hole 15 (see FIG. 5) formed in a substantially central portion of the flange member 14.

The flange member 14 has a thickness of 3 mm to 5 mm.
The area is larger than the internal area of the front pillar 1 by about 5 mm (see FIG. 5). Flange member
Originally, 14 is similar to the sectional shape of the front pillar 1 as shown in FIG. 4, but is shown as a square for convenience.

Antenna storage cylinder 5 and antenna cord 6
An upper stopper clip 16 and a lower stopper clip 17 for fixing the antenna housing cylinder 5 and the antenna cord 6 from both sides are attached to both sides of the flange member 14 attached to the outer periphery of the.

Since this embodiment is constructed as described above, when the flange member 14 is inserted into the front pillar 1, as shown in FIG. 6, it is inserted at the entrance of the antenna hole 8 provided in the front pillar 1. The flange member 14 is folded and then pushed into the inside of the front pillar 1 (see the arrow in FIG. 6).

The flange member 14 inserted inside the front pillar 1 expands inside the front pillar 1 and abuts against the inner wall of the pillar 1, so that the engine sound transmitted through the inside of the front pillar 1 into the vehicle interior and the wind during running. Insulate noise, etc.

Although the material of the flange member 14 is a rubber sheet, the same effect can be obtained even if the flange member 14 is made of foamed urethane or sponge.

[0023]

As described above, according to the present invention, since the flange member of the elastic sheet is provided on the outer periphery of the antenna housing cylinder, if the antenna housing cylinder is inserted into the front pillar, the flange member of the elastic sheet is fronted. Since the inside of the pillar is shut off, it is possible to reduce the propagation of engine noise and other various noises into the vehicle interior, and the work in the mounting process to the vehicle body is facilitated. In addition, it is possible to prevent noise generated when the antenna housing cylinder touches the inner wall of the front pillar during traveling. Further, the antenna cord can be easily held by the flange member by the flange member.

According to the second aspect of the present invention, since a plurality of flange members are attached to the outer periphery of the antenna housing cylinder at intervals, it is possible to more effectively reduce various noises than when only one flange member is provided. Propagation can be reduced.

Further, according to the invention described in claim 3, since the shape of the flange member is similar to the cross-sectional shape of the front pillar, and the area is made slightly larger than the internal area of the front pillar, the flange member is formed on the inner wall of the front pillar. Can be closely attached to, and noise can be reliably blocked.
