  However, in the conventional configuration, the substrate is first positioned by the positioning guide on the back surface of the escutcheon body, then the touch panel is positioned by another positioning guide, and the liquid crystal is positioned by another positioning guide. A plurality of guides must be provided on the back surface of the scuttle, the structure of the escutcheon body is complicated, positioning is difficult, and costs are high.

  Accordingly, an object of the present invention is to provide an escutcheon and a vehicle-mounted acoustic device that can solve the problems of the conventional techniques described above, simplify the structure, and can be easily assembled and manufactured.

  According to the present invention, a substrate, a touch panel, and a liquid crystal are sequentially arranged on the back surface of the escutcheon main body, a cover is further disposed, and the cover is screwed to the back surface of the escutcheon main body. A positioning projection is provided, and at least the substrate and the touch panel are positioned by a substantially L-shaped positioning projection.

  In the present invention, since the substrate and the touch panel are positioned by a common substantially L-shaped positioning protrusion, there is no need to provide separate positioning guides as in the prior art, and the structure of the escutcheon body is simplified and positioning is easy. become.

  In this case, the protrusion may be provided corresponding to each corner of the substrate and the touch panel. The substrate may be formed in a substantially U shape corresponding to the three sides of the escutcheon body. The substrate may be provided with a substantially L-shaped positioning hole, and the protrusion may be fitted into the positioning hole for positioning. The touch panel may be positioned by contacting a corner of the touch panel with the protrusion.

  Further, in the in-vehicle audio device provided with the playback device main body and the escutcheon provided on the front surface of the main body, the escutcheon sequentially arranges the substrate, the touch panel, and the liquid crystal on the back surface of the escutcheon main body, and further arranges the cover. The cover may be configured to be screwed to the back surface of the escutcheon body, a substantially L-shaped positioning protrusion may be provided on the back surface of the escutcheon body, and at least the substrate and the touch panel may be positioned by the substantially L-shaped positioning protrusion. .

  In the present invention, since the substrate and the touch panel are positioned by a common substantially L-shaped positioning protrusion, there is no need to provide separate positioning guides as in the prior art, the structure of the escutcheon body is simplified, and positioning is easy. Become.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 10 denotes an in-vehicle acoustic device, and the in-vehicle acoustic device 10 includes a reproduction apparatus main body 11 and an escutcheon 13 disposed on the front surface thereof. Various selection switches (push buttons) 15 made of resin are arranged around the escutcheon 13 and are not shown. When the escutcheon 13 is opened, a CD, a DVD, or the like is inserted into the front part of the playback device main body 11. A free insertion slot is exposed, and a CD, DVD, or the like inserted through the insertion slot enters the reproduction apparatus main body, and recorded information is reproduced.

In this configuration, as shown in FIG. 2A, the escutcheon 13 is in contact with the box-shaped escutcheon main body 21 and the back surface thereof, and is formed in a substantially U-shape corresponding to the three sides 21A, 21B, 21C of the escutcheon main body 21. And a glass touch panel 25 placed on the substrate 23 and a liquid crystal module 27 placed on the touch panel 25.
A fixing plate 29 is overlaid on the liquid crystal module 27, a liquid crystal circuit 31 is disposed thereon, and a cover 33 is further disposed.
The cover 33 is threaded with screws 35 at four corner positions, and the screws 35 are screwed into bosses (not shown) provided on the back surface of the escutcheon body 21, thereby assembling the escutcheon 13.

In the present embodiment, a pair of substantially L-shaped positioning projections 37 are provided on the back surface of the escutcheon body 21, and the substrate 23 and the touch panel 25 are positioned by the substantially L-shaped positioning projections 37 as shown in FIG. 2B. ing.
That is, the pair of protrusions 37 are provided corresponding to the respective corners of the substrate 23 and the touch panel 25.
A substantially L-shaped positioning hole 39 is formed at each side corner of the lower end of the substrate 23, and the projection 37 is fitted into the positioning hole 39, whereby the substrate 23 is positioned. The touch panel 25 is positioned with its corners in contact with the inner surface 37 </ b> A of the substantially L-shaped protrusion 37.

  In the present embodiment, since the substrate 23 and the touch panel 25 are positioned by a common substantially L-shaped positioning projection 37, at least the positioning of these members is performed vertically and horizontally for each member, as in the past. The positioning guide (not shown) may not be provided separately, and the structure of the escutcheon main body 21 is simplified, thereby making it possible to reduce the size and facilitate the positioning operation. As shown in FIG. 2A, in the substrate 23 formed in a substantially U shape corresponding to the three sides 21A, 21B, 21C, the upper ends 23A, 23A of the substrate 23 are easily deformed to the arrow A side and are difficult to position. . In the present embodiment, a substantially L-shaped positioning hole 39 is formed in each of the corners of the lower end 23B of the substrate 23, and the projection 23 is fitted into the positioning hole 39 to position the substrate 23. The substrate 23 can be accurately positioned regardless of the deformation of 23A and 23A.

  As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this. In the above configuration, the positioning protrusions 37 are provided corresponding to both side corners of the lower ends of the substrate 23 and the touch panel 25. However, the present invention is not limited to this, for example, corresponding to both side corners of the upper ends of the substrate 23 and the touch panel 25. May be provided. The protrusion 37 may position not only the substrate 23 and the touch panel 25 but also the liquid crystal module 27, the fixing plate 29, the liquid crystal circuit 31, the cover 33, and the like at the same time.

It is a perspective view which shows one embodiment of this invention. A is an exploded perspective view of an escutcheon, and B is an enlarged view of a positioning portion.
