Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for a rod antenna in a vehicle.

[Prior Art] As shown in FIG. 1, in a cab-over type truck, a windshield 20 is attached to the front of the cab with a shield 24, and a triangular window 22 is attached to the door.
A side glass 23 is provided. A door mirror 21 is attached to the door by a stay 2. A rod antenna 15 is supported on the outer wall surface of the front pillar 12 by a pair of upper and lower mounting members 3 and 4. The above mounting structure has the following problems.

a Noise called wind noise is generated by the flow of air passing through the gap between the rod antenna 15 and the outer wall surface of the front pillar 12.

b. Raindrops that hit the windshield 20 are blown toward the sides of the vehicle body, pass through the gap between the rod antenna 15 and the outer wall surface of the front pillar 12, and tend to adhere to the door mirror 21 and the triangular window 22.

In order to solve the above problem, for example,
In the device disclosed in Japanese Patent No. 115844, the rod antenna is attached to the center of the front pillar by a stay, but since the stay is short, it is less effective in preventing raindrops from adhering to the side glass. In addition, as disclosed in Utility Model Application Publication No. 49-7845,
If the rod antenna is covered with a flexible insulating material such as rubber, it cannot be used as a grip to support the body when cleaning the windshield of a large truck.

[Problems to be Solved by the Invention] In view of the above-mentioned problems, an object of the present invention is to provide a mounting structure for a rod antenna that does not cause wind noise or raindrops to adhere to the antenna mounting portion.

[Means for Solving the Problems] In order to achieve the above object, the configuration of the present invention is such that the mounting edge of the mounting member, which has an L-shaped cross section and has approximately the same length as the side edge of the windshield, is attached to the side of the front pillar. The base end of the rod antenna is held by a retaining plate on the flange of a mounting member that is closely fixed to a wall surface and protrudes outward from the front pillar of the vehicle body.

[Function] Since the mounting member 6 is arranged so that there is no gap between the rod antenna 15 and the front pillar 12, generation of wind noise and adhesion of raindrops to the triangular window are prevented.

[Embodiment of the invention] As shown in FIG. 2, a rod antenna 15 is supported by a mounting member 6 on the outer wall surface of a front pillar 12 that constitutes a side wall of the front end of the cab. The mounting member 6 is molded from synthetic resin and has an L-shaped cross section.
The length is approximately the same as the side edge of the windshield 20.

As shown in FIG. 3, a windshield 20 is supported by a shield 24 on the front wall surface of the front pillar 12, while a side wall surface 7 of the front pillar 12 is supported by a shield 24.
The mounting edge 11a of the mounting member 6 is supported. The mounting member 6 consists of a main body 11 and a holding plate 16. The main body 11 is made of resin and has an approximately L-shaped cross section.
a is superimposed on the front pillar 12, and is fixed by screwing a screw 13 passing through the mounting edge 11a into a nut 14 welded to the inner surface of the front pillar 12. On the other hand, a groove 25 having a semicircular cross section and extending in the longitudinal direction is provided on the back surface of the ridge 11b of the main body 11, and the rod antenna 15 is fitted into the groove 25 and fixed by a presser plate 16 made of resin. The holding plate 16 is also provided with a groove 25a having a semicircular cross section.
The holding plate 16 has a nut 18 embedded in the ridge 11b.
A screw 17 passing through the holding plate 16 is screwed into the holding plate 16 to fix it.

According to the invention, the elongated mounting member 6 extends along the front pillar 12 and
Since the rod antenna 15 is closely attached to the side wall surface of
There is no gap between the front pillar 11b and the front pillar 12, so the air flow while the vehicle is running is limited to the flange 11b.
Since the wind noise is deflected toward the outside of the front pillar 12 along the front surface 8 of the front pillar 12, wind noise is reduced.

Raindrops that hit the windshield 20 are blown to the side, but accumulate on the front surface 8 of the ridge 11b.
Since it falls along the ridge 11b, the door mirror 2
Adhesion of water droplets to the triangular window 1 and the triangular window 22 is suppressed, and good visibility is ensured even in rainy weather.

Note that since the width of the protruding edge 11b is approximately the same as that of the front pillar 12, the blind spot does not change.

Furthermore, since the mounting member 6 has an L-shaped cross section, the worker can ride on the bumper and use it as a grip when wiping the windshield 20, eliminating the need to provide a new grip, and improving design and aerodynamic properties. is also advantageous.

In the embodiment shown in FIG. 4, the mounting member 6 has a cross section L
In addition to the letter-shaped mounting edge 31a and the main body 31, it is provided with a protruding edge 31b that projects rearward from the main body 31, and the protruding edge 31b strengthens its function as a grip. The mounting edge 31a is superimposed on the side wall surface 7 of the front pillar 12, and is fixed by screwing a screw 13 passing through the mounting edge 31a into a nut 14 welded to the inner surface of the front pillar 12. On the other hand, a groove 25 having a semicircular cross section and extending in the longitudinal direction is provided on the outer surface 32 of the flange 31b of the mounting member 6. Groove 25
The rod antenna 15 is engaged with the rod antenna 15, and is held between the resin holding plates 36. The holding plate 36 is also provided with a groove 25a having a semicircular cross section. The presser plate 36 is attached to the nut 18 embedded in the ridge 31b.
It is fixed by screwing together a screw 17 that passes through it.

In this embodiment, when the mounting member 6 is provided with a projecting edge 31b that projects diagonally rearward, the windshield 20
The wind hitting the triangular window 2 is largely deflected outward.
2 and the side glass 23 and flows backwards, so even if it rains sideways, the side glass 2
Raindrops are prevented from adhering to 3.

[Effects of the invention] As described above, the present invention fixes the mounting edge of the mounting member, which is approximately the same length as the side edge of the windshield and has an L-shaped cross section, in close contact with the side wall surface of the front pillar.
Since the base end of the rod antenna is held between the protruding edge of the mounting member that protrudes outward from the front pillar by a presser plate, there is no gap between the rod antenna and the front pillar, and air passes through the outside of the mounting member. This eliminates wind noise generated from the gap between the rod antenna and the front pillar.

In addition, raindrops that hit the windshield flow sideways and are collected between the protruding edge of the mounting member on the front pillar and the shield that supports the side edge of the windshield on the front pillar, and then flow down. There is less water droplet adhesion to the area, ensuring good visibility even on rainy days.

Since the mounting member has an L-shaped cross section, the worker can ride on the bumper and use it as a grip when wiping the windshield.
