Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a vehicle audio board mounting device used in automobiles and the like.

[Technical background of the invention and its problems]

In general, vehicle speakers installed in cars are
It is easiest for passengers in the car to hear, has a great acoustic effect, and can be installed in a location that does not sacrifice interior space, but in passenger cars, it is often installed in the rear tray behind the back seat. .

When installing this rear tray, there are two types: one is to directly attach a speaker unit to the rear tray, and the other is to place a speaker box on the rear tray. When directly attaching the speaker unit to the rear tray, depending on the car model, there may be obstacles in the trunk, such as a gas tank.
There are some speakers that cannot be installed because the rear part of the speaker unit comes into contact with the speaker unit. Furthermore, in order to remove the existing rear tray in order to install the speaker unit, the rear seat must be removed first, which is a time-consuming process.

[Purpose of invention]

The present invention is an attempt to solve the above-mentioned problems, and aims to make it possible to easily attach a speaker unit to the rear tray portion of a vehicle.

[Summary of the idea]

The present invention consists of a full plate that is attached to a speaker unit and mounted on the rear tray at the rear of the vehicle;
A nut is provided on the buttful plate, and a guide body is provided at the bottom of the nut and has a tapered guide hole with a downwardly enlarged diameter. The speaker unit is mounted on the rear tray together with the baffle plate.

[Example of idea]

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 5.

In FIG. 1, 1 is a car body, 2 is a rear seat inside the car body 1, and 3 is a rear tray behind the rear seat 2.

Reference numeral 5 denotes an audio board, and as shown in FIGS. 2 to 4, this audio board 5 has a buttful plate 6 formed in approximately the same shape as the rear tray 3, and has circular shaped plates on both sides of the buttful plate 6. A speaker hole 7 is formed, and a plurality of elongated holes 8 are intermittently connected along concentric positions on the outside of the speaker hole 7, leaving connecting portions 9. A plurality of mounting nuts 10 are provided near the slots 7 and 8. Further, a curtain plate 11 is provided at the lower part of the front edge of the baffle plate 6. Furthermore, a decorative sheet 12 is attached to the outer surfaces of the baffle plate 6 and curtain plate 11, leaving speaker holes 7.

Further, a prismatic support 13 is provided at the center of the back surface of the baffle plate 6, and mounting portions 14 are provided on both sides of the support 13. As shown in FIG. 5, this mounting portion 14 is a guide body having an embedded nut 15 embedded in the buff-full plate 6, and a tapered guide hole 16 whose diameter is enlarged at the lower part of the embedded nut 15. 17 is fixed. Then, insert the mounting screw 18 from inside the trunk of the vehicle body 1 into the guide hole 16 of the guide body 17 through the washer 19 and the through hole 20 of the rear tray 3, screw it into the embedded nut 15, and attach the buttful plate 6. It is designed to be fixed on the rear tray 3.

When assembling the speakers, as shown in FIG.
A speaker unit 21 of a predetermined diameter is disposed on the outer surface of the baffle plate 6, and its flange 22 is brought into contact with the outer surface of the buff-full plate 6.
Screw together the screws 23 and fix.

In addition, if the speaker unit 21 has a large diameter, the connecting portion 9 between the long holes 8 of the buffer plate 6 is cut to form a large diameter speaker hole along the long holes 8, and the large diameter speaker hole is formed along the long hole 8. A speaker unit 21 with a large diameter is disposed in the hole, and its flange 22 is similarly fixed to the baffle plate 6 with screws 23.

Note that the flange 22 of the speaker unit 21 may be fixed using wood screws or the like.

Next, the baffle plate 6 to which the speaker unit 21 is attached is placed on the rear tray 3 via the support 13, and fixed on the rear tray 3 by screwing the mounting screw 18 into the embedded nut 15 as described above. .

In this way, the full board 6 is attached to the rear tray 3.
The lower part of the speaker unit 21 can be easily installed without coming into contact with obstacles by installing the speaker unit 21 at intervals using the support member 13 and the curtain plate 11, and the use of a thick board for the buttress plate 6 also improves acoustic performance. You can get good playback sound.

In addition, as in the above embodiment, in addition to forming the left and right speaker holes 7 in one buttful plate 6, the sixth
As shown in the drawings and FIG. 7, separate left and right buffle plates 6 may be formed, and each buffle plate 6 may be provided with speaker holes 7, elongated holes 8, mounting portions 14, and the like. By doing so, it can be applied to various types of vehicles.

In each of the above embodiments, a long hole 5 is provided along a concentric circle outside the speaker hole 7 so that speaker units of two different diameters can be attached. The speaker units may be provided in duplicate along two concentric circles so that speaker units of three different diameters can be attached. Further, the large diameter speaker hole formed by the speaker hole 7 and the elongated hole 8 is not limited to a circular shape, and may be formed into an oval shape or the like depending on the shape of the speaker unit.

[Effect of idea]

According to the present invention, the speaker unit can be easily placed by attaching the speaker unit mounted on the rear tray at the rear of the vehicle. Even if there is a considerable distance between the rear tray and the rear tray, and you are trying to fix it with the mounting screws from inside the trunk, the tips of the mounting screws will be guided by the tapered surface of the guide hole of the guide body, and will reach the nuts smoothly and immediately. It can be tightened and fixed, so the buttful plate can be easily and reliably attached.
