Description

[Detailed Description of the Invention] [Object of the Invention] The present invention relates to the invention of an antenna mounting mechanism for the edge of a vehicle body, in which the antenna is supported and set by using the edge of the trunk of the automobile or the like, and is detached when washing the vehicle. In the mounting mechanism thus obtained, an attempt is made to provide a mechanism that facilitates the attachment / detachment operation so that the supporting relationship is stable and appropriate in setting the base body in the convex portion or step structure at the vehicle body edge portion. It is a thing.

(Industrial application field) An antenna mounting mechanism for fixing an antenna using the trunk lid and other edges of the vehicle body.

(Prior Art) Various proposals have heretofore been made to support an in-vehicle antenna by utilizing an opening part such as a trunk part of an automobile, a fitting seat part thereof, and a side girder. That is, the conventional general in-vehicle antenna mounting is a so-called embedded type in which a hole is bored in the vehicle body and the antenna section body is directly mounted, but the opening section body such as the trunk section and its fitting are attached. If the joint is used, there is an advantage that the antenna can be attached without the need for machining damage to the vehicle body. −9331

(Problems to be solved by the invention) However, in the conventional device as described above, the attachment is generally performed by point-tightening with respect to the vehicle body edge portion with a fixing means such as a set screw, so that a considerable length is required. However, there is a disadvantage in that the antenna having a can not always be fixed stably. That is, although a plurality of fixing means such as the set screws as described above are provided, it is difficult for the point fixing means to be stable even with a plurality of set screws.

For this reason, a spacer or a seat plate may be interposed between the above-mentioned point fixing means and the edge of the vehicle body in order to achieve a surface joint. -8328), pp. 54-159943, pp. 59-94410
Can be said to be one of such types, but especially the above-mentioned proposals to be attached such as a trunk lid cannot be completely established only by the respective disclosed techniques. That is, the back surface of the edge of the trunk lid or the like uses a sealing material in consideration of waterproofness in which the vehicle body plate is superposed, and the step portion 41 or the convex portion 42 is formed as shown in FIG. 8 or 9. In such a case, the fixing means 9 is used.
However, even if the spacer or the seat plate 15 is interposed, stable fixing cannot be obtained even if the fixing means 9 is pressed. That is, as shown in FIG. 10 or FIG. 11, a gap 11d remains between the seat plate 15 and the vehicle body edge portion 11e, and there is a high possibility that the pressing point by the fixing means 9 is directed to the step portion 41. Therefore, the seat plate 15 is inclined, so that the seat plate 15 tends to slide due to the point pressure of the solid means 9.
Since the support plate 22 moves between the vehicle body edge 11e and the inside of the support plate 22 fitted to the vehicle body edge 11e for mounting, a gap is generated, and a rubber pad 22d or the like is used. However, the general mounting condition becomes very unstable. In other words, in such a state, there is a high possibility that the antenna mounted at a corner will rattle due to vibrations during vehicle running.

"Constitution of device" (Means for solving the problem) A base plate which is joined to a support plate and an outer surface of the vehicle body is attached to a base end of an antenna mounted on the vehicle body,
In combination with the joining of the base member to the outer surface of the vehicle body, the fixing means screwed into the fitting portion of the support plate while being fitted to the vehicle body edge portion is tightened to the inner surface of the vehicle body edge portion. In the one that is equipped with the above antenna and fixed to the vehicle body,
An interposer piece is located between the vehicle body edge portion and the fixing means, and a step portion that engages with a convex portion or a step portion formed on the vehicle body edge portion is formed on the interposer piece. The antenna mounting mechanism for the edge of the car body.

(Operation) By the step portion of the intervention piece being positioned so as to be opposed to the convex portion or the step portion formed on the vehicle body edge portion,
The surface of the interposition piece located at the edge of the vehicle body facing the fixing means is held in a state of being substantially parallel to the vehicle body surface. Therefore, even if the intervening piece is not tilted by the point pressing by the tightening of the fixing means, the gap between the intervening piece and the vehicle body edge is substantially prevented.

As a result of the above, regardless of the presence of the convex portion or the stepped portion on the edge of the vehicle body, the mounting of the antenna by the fixing means can be sufficiently stabilized, and highly reliable mounting can be obtained.

It should be noted that an adhesive means such as a double-sided adhesive tape can be attached to the joint surface of the interposer piece with respect to the vehicle body edge, and the one provided with the adhesive means can be attached to the vehicle body edge by pressing the fixing means as described above. It is possible to accurately fix it to the vehicle body, and it is necessary to attach and detach the interposition piece to and from the vehicle body edge portion every time even when the base body 2 is attached and detached when the antenna is attached and detached.

(Embodiment) A concrete embodiment of the present invention as described above will be described with reference to the accompanying drawings. This embodiment shows a case where an in-vehicle antenna is attached to a trunk lid of an automobile. The antenna mounting mechanism of the present invention, which is mounted on the vehicle body by utilizing the trunk lid 11 of the vehicle as shown in FIG. 1, is similar to the above-mentioned proposal by the applicant of the present invention, etc. And the support plate 1 fixed to the base end member 3, which has the base end member 3 attached to the base end of the antenna 5 so as to introduce and connect the cable 6.
The base plate 2 is joined to the edge of the base plate from the upper surface as shown in FIG. 3, and the support plate 1 has a lower end part of the base member 3 as shown in FIGS. Is fixed to the lower end portion of the base end member 3 by a collar 31.
And a screw cylinder 32 is projected downward from the flange 31. The screw cylinder 32 is inserted into the insertion hole 1a of the support plate 1, and the nut 8 is fastened to the screw cylinder 32. Made to be fixed. As shown in FIG. 3, a bent portion 14 is formed on one side of the support plate 1 so as to join the rear lid 12 with the trunk lid 11 closed. Further, an engaging thread 34 is formed above the brim portion 31 of the base end member 3 via a reduced diameter portion 33, and the engaging thread 34 is fastened to the base portion body 2 described above. A lock nut 4 for fitting is screwed, and the base portion 2 has a fitting opening 21 for receiving the collar portion 31 as described above.
An opening 23 having a width sufficient to receive the reduced diameter portion 33 by sliding is formed on one side of the fitting port 21. Further, as shown in FIG. 2, setting seats 22 for the trunk lid 11 are formed on both sides of a central portion formed by bulging the fitting opening 21 and the opening 23 as shown in FIG.
The fitting portion 25 is formed by bending back on one side of the setting seats 22, and the fitting portion 25 is fitted to the end edge of the trunk lid 11 and fixed to the trunk lid 11 with the fixing screw 24. Made of

In the present invention having the above-mentioned structure, in order to deal with the step 41 or the convex portion 42 at the edge of the trunk lid 11 as described above, the interposer piece 16 as shown in FIGS.
Is used, that is, a step 17 is formed in the middle, and the step 17
7 along the side edge of the step 41 or the convex portion 42 in
As shown in the drawing, the receiving set is performed and the fixing means 9 as described above is used for tightening. The interposer piece 16 has a length 1 or more corresponding to the setting seat 22 as shown in FIGS. 4 and 5, and each fitting portion 2 located on both sides of the opening 23 as described above.
The fixing means 9 and 9 of 5 and 25 are crotch-fitted and positioned as a band. The thickness of the laminated plate 16b is selected according to the heights t ₁ and t ₂ of the step 41 or the convex portion 42.

Of course, the above-mentioned interposer piece 16 may be formed of an integrally thick and unequal material with a step formed in the middle, but it can be formed by polymerizing plate materials obtained in mass production. That is, by using a relatively wide base plate 16a and a relatively narrow overlapping plate 16b and joining them at spot welding points 18 as shown in FIG. In this case, it is preferable to form a notch 19 on one side of the intervention piece 16 as shown in FIG. Further, in order to stabilize the attachment, as shown in FIG. 4 or FIG. 6, an adhesive layer such as a double-sided adhesive tape 20 is formed on the surface on which the step portion 17 is formed, so that the fixing means as described above. 9
The interposition piece 16 can be adhered to the vehicle body edge 11e such as a trunk lid by fixing by the fixing by, and the interposition piece 16 can be removed when the setting seat 22 of the base body 2 is detached by the fixing means 9. It is possible to eliminate the need for repeated setting of the interposer piece 16, as well. Further, it is apparent that an adhesive layer such as such a double-sided adhesive tape may be adopted instead of the spot welding for joining and integrating the base plate 16a and the laminated plate 16b as described above.

In the case of the illustrated embodiment as described above, the trunk lid 11 forming the edge of the vehicle body is attached to the rear ender 12.
