Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an automobile antenna that also serves as a pole for a tail marker that detects a rear barrier or the like when the automobile retreats.

<Prior Art> Generally, an automobile antenna is fixed to a front bumper, a rear bumper, a top rail on a side surface of a vehicle body or the like, or is integrally incorporated into a front pillar of a vehicle body or a rear side of a vehicle body. It can be expanded and contracted accordingly.

On the other hand, on the front and rear bumpers on the opposite side of the driver's seat of the car,
The marker pole is fixedly attached, and in particular, the tail marker pole can detect the distance from the rear barrier or the like when the vehicle retreats.

As described above, conventionally, the antenna and the pole for the tail marker are completely separate parts.

<Problems to be solved by the invention> By the way, since the conventional marker pole is directly fixed to the bumper, if the tail marker pole collides with a barrier or the like during retreat, the bumper also naturally blocks the barrier. The bumper may be damaged by coming into contact with such objects.
Originally, automobile bumpers were intended to protect the vehicle body in the event of a collision with a barrier, etc., but recent bumpers also serve as a decorative feature, so in normal conditions they tend to dislike small damage. is there. Further, as described above, conventionally, the antenna and the pole for the tail marker are completely separate parts, and therefore improvement has been desired from the viewpoint of reducing the number of parts.

The present invention has been made based on the above-mentioned circumstances, and an object thereof is to be able to detect the distance between a rear bumper and a barrier or the like before the rear bumper collides when the vehicle retreats.

<Means for Solving Problems> The structure of the present invention to achieve the above object is to install an antenna mounting member at the base end of an automobile antenna main body, and mount the antenna mounting member on a guide rail fixed to the vehicle body side. It is mounted so as to be slidable in the front-rear direction, and the antenna mounting member and the operating section installed on the driver's side are connected via a tow cable, and the operating section is operated to project the vehicle antenna to the rear of the bumper. The feature is that it has been made possible.

<Operation> According to the vehicle antenna of the present invention having the above-described configuration, the antenna has a function as an antenna, and when the vehicle moves backward, the operation portion is operated from the driver's seat so that the base end portion of the antenna moves to the rear of the bumper. As it sticks out a certain distance, it also has the function of a pole for a tail marker,
The antenna comes into contact with the rear bumper before it can detect the distance from the barrier.

<Embodiment> Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing a mounting state of a vehicle antenna according to an embodiment of the present invention, FIG. 2 is an exploded perspective view showing details of an antenna mounting portion according to the present invention, and FIG. 3 is a vehicle according to the present invention. FIG. 1 is a schematic configuration diagram showing an antenna operation mechanism, in which reference numeral 1 denotes an automobile, 2 denotes a front bumper, 3 denotes a rear bumper, and 4 denotes an antenna body which is vertically expandable and contractible.

An antenna mounting member 5 is installed at the base end of the antenna body 4 at right angles to the extending direction of the antenna body 4.
Guide grooves 5a for sliding are formed on both side surfaces of the antenna mounting member 5.

On the other hand, on the side of the upper surface of the rear bumper 3 fixed to the rear part of the automobile 1, a guide rail 6 having a predetermined length along the longitudinal direction of the vehicle body is fixed via a bracket 7. The guide portion 6a is engaged with the guide groove 5a of the antenna mounting member 5 so that the antenna mounting member 5 can be slid in the front-back direction of the automobile 1.

Further, in the rail groove 6b of the guide rail 6, a stopper portion 8 for restricting the sliding amount of the antenna mounting member 5 is formed at the rear end portion, and the stopper portion 8 is formed at the front end portion after the antenna mounting member 5 is assembled. The stopper pin 9 for preventing the slip-off is attached.

Further, a grooved pulley 10 acting as a fixed pulley is rotatably supported at the upper end or the rear end of the side surface of the guide rail 6, and is attached to the front part of the antenna mounting member 5 via a metal fitting 11 at one end. One of the two tow lines 12 and 13 to which the
A tow line 12 of a book is wound around the grooved pulley 10 and guided to the driver's seat side.

Here, the tow lines 12 and 13 are composed of outer tubes 12a, 13a and inner wires 12b, 13b, respectively, and the tips of the inner wires 12b, 12b are operation knobs 14 as operation parts installed on the driver side. Sticked to 15.

In addition, pulling the operation knobs 14 and 15 allows the tow lines 12 and 13 to be pulled.
Are pulled individually. For example, when the operation knob 14 is pulled, the pulling direction of the tow line 12 is changed by the grooved pulley 10, and the antenna mounting member 5 is slid to the rear of the vehicle body. When the user pulls 15, the antenna mounting member 5 can be slid directly in front of the vehicle body. During operation of the operation knob 14 or 15, the other operation knob 15 or 14 is free and is pulled back by the slide length of the antenna mounting member 5 via the tow lines 12 and 13. . The operating knobs 14 and 15 are installed on the side of the driver's seat, on the instrument panel, or the like, although there is no particular designation.

According to the vehicle antenna configured as described above,
It usually has a function as an antenna for a radio,
The antenna mounting member 5 is located forward with the operation knob 15 pulled. Further, when there is a barrier or the like behind when the vehicle moves backward, by pulling the operation knob 14, the antenna mounting member 5 slides on the guide rail 6 and the antenna body 4 can be projected rearward. The bumper 3 will not be damaged even if the vehicle body is retracted until the antenna body 4 contacts the barrier or the like.

<Effect of the Invention> As described above in detail, according to the antenna for a vehicle of the present invention, the antenna mounting member to which the antenna body is mounted can be projected rearward from the rear bumper of the vehicle body by the operation from the driver's seat side. Since it is configured so that when the vehicle retreats, it can be confirmed that if the antenna body is projected rearward from the rear bumper, the vehicle can be retracted until the antenna body contacts the barrier etc., and damage to the rear bumper is prevented. be able to. Further, since the antenna and the tail marker pole are shared, the number of parts can be reduced.
