Description

[Detailed explanation of the idea] The present invention relates to audio equipment for automobiles.

So-called display-type automotive audio equipment, in which a front panel, a rotary heir, etc. are attached to the main body of the equipment, has traditionally been the first
The structure shown in the figure is generally used.

In FIG. 1, reference numeral 1 denotes a chassis body of an automobile audio equipment, and 2 denotes a nose portion which is attached to the front surface of the chassis body with screws 3.degree. 3, and is made of synthetic resin.

4, 4 are shafts for volume adjustment, tuning, etc., 5 is the front panel, 6.7 is a special nut and washer attached to the shafts 4, 4 behind the front panel 5, 8
, 9 are washers and nuts attached to the shafts 4, 4 in front of the front panel 5, and 10.11 are the shafts 4, 4.
The large-diameter rotary heir is attached to the tip of the rotary, and the small-diameter heir is the rotary heir.

12. 12 is a decorative plate (marking plate) for hiding the shaft insertion holes 13, 13 drilled in the front panel 5.
It is.

In addition to the standard specification set plate 12, the marking plates include an inner plate 12' and an outer plate 12.
'' is provided in a separate package, and the user can
It is designed to be selectively installed according to the shaft mounting hole of several standardized chassis.

However, if it is an in-dash type car audio device with a structure like that shown in Figure 1, it is necessary to remove the nose part 2 from the chassis body 1 and pull it forward when replacing parts inside the nose part 2. In this case, the front panel 5 must be removed, but in order to remove the front panel 5, the legitimate children 10 and 11
, nuts 6°8, washers 7.9, etc. had to be removed, making the work extremely troublesome.

In the case of an under-dash type, in order to remove the nose part 2 from the chassis body 1 without removing the front panel 5, insert the screwdriver 14 into the gap between the front panel 5 and the chassis body 1, as shown in FIG. from the diagonal direction (direction A) to remove the screws 3, 3, etc., or use a special tool (not shown) that can be used from the front side of the front panel 5 to the back side as shown in B. ) to remove the screws 3, 3, but in either case the workability will be very poor.

In view of this, the present invention aims to provide an automobile audio device in which the nose section can be easily removed from the chassis body using ordinary tools without having to remove the front panel one by one. An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

In FIGS. 3 and 4, the same numbers as in FIG. 1 are used for the same parts as in FIG. 1.

As shown in FIGS. 3 and 4, the present invention is characterized in that the front panel 5 is provided with through holes 15, 15, . . . for a tool (driver) 14.

That is, in the front panel 5, there are through holes 15, 15, .
・Drilled.

In addition, 20 is a through hole 15.15 in the marking plate 12.
... is a shaft insertion hole provided separately.

When removing the nose section 2 from the chassis body 1 when replacing parts, etc., slightly loosen the nut 8 attached to the shaft 4 and rotate the marking plate 12 as shown in Figure 3 to remove the tool through hole. ... will appear, so as shown in Fig. 2C, insert a regular screwdriver 14 from the front of the front panel 5 vertically into the tool holes 15, 15, remove the screws 3, and remove the nose. The part 2 can be removed from the chassis body 1.

Since the nose part 2 can be removed from the chassis body 1 in this way, the nose part 2 can be pulled out forward through the nose part insertion hole 19 of the front panel 5, and repairs, replacements, etc. inside the nose part 2 can be performed. I can do it.

Note that if the nose part 2 is made of soft synthetic resin or if a cut groove (not shown) is provided on the side surface of the nose part to provide elasticity, the nose part 2 can be inserted through the nose part of the front panel 5. Hole 1
9 can be easily pulled out forward.

Note that the top plate 1' that constitutes the chassis body 1 has a notch 17,
If a mounting part 18.18 formed with a 17 is provided and the top plate 1' is inserted between the bottom lid 1'' and the nose part 2, the nose part 2 can be easily attached by just turning the screwdriver 14 several times. It can be removed from the chassis body 1.

In this way, when it is necessary to remove and pull out the nose section 2 from the chassis body 1, such as when replacing parts inside the nose section 2, it is not necessary to remove the front panel 5 each time, making the work extremely easy.

When attaching the marking plate 12 to the front panel 5, double-sided adhesive tape may be used, or it may be held down using washers 9, nuts 8, etc. attached to the shafts 4, 4, without using adhesive tape. good.

The marking plate 12 is shaped so that when the washer 8 attached to the shaft 4 is slightly loosened and the marking plate 12 is rotated, the tool passage hole 15.15 in the front panel 5 appears to the extent that the screwdriver 14 can be inserted therethrough. Just leave it as .

As described above, the automotive audio equipment according to the present invention has a tool passage hole in the front panel, so when removing the nose part from the chassis body when replacing parts, etc., there is no need to remove the front panel each time, and the decorative plate can be removed. Since all you have to do is shift it, the work is extremely easy.

In particular, the nose section has many parts that are prone to failure, such as lamps, indicators such as light emitting diodes, and dial ropes, so the audio equipment for automobiles of the present invention is extremely effective.
