Description

[Detailed explanation of the idea] The present invention relates to in-vehicle audio equipment.

Conventionally, when attaching the nose section of in-vehicle audio equipment to the cabinet, it was generally fixed with screws, but this took a lot of man-hours and once assembled, for example, it was difficult to replace the indicator lamp located inside the nose section. Therefore, in order to remove the nose part, it was necessary to remove the decorative escutcheon and then remove the screws that fixed the nose part.

In particular, after an audio device has been built into the dash board of an automobile, it is very time-consuming to perform necessary maintenance on the device, which can only be done by specialized repair personnel.

In view of this, the present invention allows the nose section of in-vehicle audio equipment to be easily attached to and detached from the cabinet body, and eliminates necessary maintenance such as replacing the indicator lamp installed inside the nose section and cleaning the recording/playback head. For the sake of simplicity, embodiments of the present invention will be described below with reference to the drawings.

In each figure, 1 is the cabinet body of the in-vehicle audio equipment, 2 and 2 are a pair of brackets with a cross-sectional shape, and 3 and 4 are adjustment shaft insertion holes drilled in the base plate portion 5 of each bracket.
and a temporary fixing protrusion insertion hole, 6 is a side plate part 7 of the bracket 2.
8, 8 are reinforcing ribs provided at the boundary between the base plate part 5 and the side plate part 7, and 9 is made of synthetic resin or the like. nose part,
10.10 is a locking hole provided on the side surface 11.11 of the nose portion.

Next, the procedure for attaching the nose portion 9 to the cabinet body 1 will be explained.

The brackets 2, 2 have temporary fixing protrusions 13. provided on the front part 12 of the cabinet body 1 in the temporary fixing through holes 4, 4.
13 and temporarily fixed to the front part 12 of the cabinet body 1.

At this time, adjustment shafts 14.14 such as tuning shafts and volume shafts provided near both ends of the front surface of the cabinet body 1.
are inserted into the insertion holes 3, 3 of the bracket 2°2.

Next, the transparent hole 10 provided in the side surface 11.11 of the nose part 9
．． At 10, lock the locking claw pieces 6, 6 of the side plate parts 7, 7 of the brackets 2, 2, and use the nake for fixing the adjustment shaft) At 15.15, attach the adjustment shaft 14. At the same time, the nose part 9 is fixed to the cabinet body 1 with the brackets 2, 2.

On the other hand, when removing the nose part 9, loosen the neck h 15.15 until the brackets 2, 2 are slightly swayed.
Although the brackets 2, 2 cannot be removed from the cabinet body 1, the brackets 2, 2 cannot be removed from the locking holes 10, 10 of the nose part 9.
Since the locking claw pieces 6, 6 are removed, the nose portion 9 can be easily removed.

Here, the structure of the bracket 2 will be explained in more detail.

The material of the bracket can be metal or resin, and the reinforcing rib 8
It may or may not be present, and may be provided as necessary.

It is easier to attach and detach the nose portion if the side plate portion 7 attached to the nose portion 9 is made flexible.

In the embodiment shown in FIGS. 1 and 2, the protrusion 13 is raised from the cabinet body 1 and inserted into the through hole 4 provided on the bracket 2 side, but this relationship is reversed and the protrusion is raised from the bracket side. You can wake me up.

Also, this protrusion is not always necessary.

When the bracket is formed of resin or the like, the locking claw piece 6 may be made to extend at right angles from the side plate portion 7, or the locking claw piece may be formed only on one bracket and not on the other. It doesn't have to be formal.

On the other hand, when the bracket is formed of a metal plate, the washer of the adjusting shaft fixing nut 15 can also be used.

The distance between the adjustment shafts 14 and 14 needs to be changed depending on the shape and dimensions of the part when the audio equipment is attached to the device mounting part of the dash board, so adjust the adjustment shaft 1 accordingly.
4.14, the adjustment shaft insertion holes 3, 3 of the bracket 2 are made oval so that the adjustment shaft 14.14 can move appropriately within the insertion holes.

In addition, there are adjustment shaft setting positions (approximately 13Qmm, 140mm, and 160mm in current car models) around these oblong holes 3, 3.
It is convenient to indicate the position of the bracket 2 with a scale 16 so that the mounting position of the bracket 2 can be easily adjusted.

Furthermore, a retaining hook part 17 for attaching the nose part 9 to the cabinet body 1 may be provided as necessary, but if the bracket is to be attached only to one side of the nose part, the bracket I
- It is possible to attach the nose part to the cabinet body more stably by providing the retaining hook part 17 on the side where the nose part is not attached.

As described above, according to the present invention, when attaching the nose part to the cabinet body, there is no need for screw fixing work, which requires less man-hours, and the nose part can be easily installed and removed, so parts can be repaired. Maintenance services such as replacement can be easily performed.
