[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle electronic device such as a car radio, a tape player, a disc player, and the like, and particularly to a casing embedded in a console panel in a vehicle interior and a front portion of this casing. The invention relates to a vehicle-mounted electronic device including a panel having a size protruding laterally from the side.

[0002]

2. Description of the Related Art The size (volume) of the housing of in-vehicle electronic devices such as car radios, tape players, and disk players is determined by the standard, and the size is so-called DIN (DIN) size. . The housing is usually embedded in a space of 1 din size (width 182 mm x depth 175 mm x height 53 mm) or 2 din size (height dimension is twice that of 1 din) formed in the console panel in the vehicle interior. It A resin panel called a nose portion, which substantially corresponds to the area of the front surface of the housing, is fixed to the front surface of the housing, and when the housing is embedded in the console panel, the panel is the front surface of the console panel. Will almost match. However, in a large foreign-made vehicle or a domestic-made vehicle, the total area of the console panel is large, and in order to match this area, the front panel of the in-vehicle electronic device is larger than the front area of the housing with a din size. May have an even wider width.

FIG. 4 is a partial cross-sectional view showing a state in which a vehicle-mounted electronic device having the above-mentioned panel having a large area is installed on a console panel. The housing 1 of this on-vehicle electronic device is made of metal and has a size of 1 din size or 2 din size. Inside the housing 1, for example, a tape drive mechanism for driving a cassette tape, an AM or FM tuner, and the like are incorporated. A resin panel 2 called a nose portion is fixed to the front portion 1a of the housing 1. For example, a connection piece 2a extending inward is integrally formed on the panel 2, and the connection piece 2a and the housing 1 are fixed by a screw 3 so that the housing 1 and the panel 2 are fixed to each other. It becomes a finished product of electronic equipment for use. As shown in FIG. 4, the panel 2 has a central operation portion A that covers the front portion 1a of the din size housing 1 and an extension operation that extends laterally beyond the front portion 1a of the din size housing 1. And a part (extension part) B. When viewed from the front of the panel 2, the central operation unit A
And the extension operation parts B extended to both sides thereof have an appearance as an integrated operation surface 2b.

Inside the central operation portion A of the panel 2, there is provided a central board 4 made of resin and having conductive patterns formed on the front and back surfaces. The central board 4 is provided with a switch S1 as an operating component.
Has been implemented. Further, inside the extension operation portion B of the panel 2, there is provided a substrate 5 also made of resin and having conductive patterns formed on the front and back surfaces. Extension operation part B of panel 2
Since the case 1 does not exist on the back surface side of the substrate 2, the substrate 5 is fixed to the back surface of the panel 2 by the pillars 6 or the like. A switch S2 is mounted on the surface of the substrate 5 as an operation component. An operation member 7 that operates as a push button is provided on the operation panel 2.
And 8 are provided, and the switches S1 and S2 are pressed by the operating members 7 and 8, respectively. In-vehicle electronic device 10 in which the casing 1 and the panel 2 are integrally assembled in advance.
Is buried in the interior of the vehicle. The console panel 11 in the vehicle compartment is formed with a space portion 11a having an inner volume of a din size, and the housing 1 is embedded in the space portion 11a. At this time, the extension operation portion B of the panel 2 is installed on the panel surface 11c of the console panel 11 at a position separated from the space portion 11a.

[0005]

As described above, the on-vehicle electronic device 10 is attached to the console panel 11 in a state where the metal housing 1 and the resin panel 2 are integrated. Further, at the time of maintenance or the like, the housing 1 and the panel 2 are removed from the console panel 11 as a unit. The central operation portion A of the resin-made panel 2 has a back surface supported by the metal casing 1, so that it can exhibit a predetermined rigidity against an external force applied at the time of assembling or disassembling. Since the back side of the extension operation portion B is not reinforced, the rigidity is extremely low. Therefore, when the end of the extension operation part B of the panel 2 is inadvertently pulled in the removal work from the console panel 11, the extension operation part B is easily damaged, and especially the central operation part A and the extension operation part B are At the boundary portion (a), stress is likely to be concentrated when an external force is applied, and cracks are likely to occur.

Further, since the substrate 5 provided on the back side of the extension operation section B is attached from the back side without any support, when the operation member 8 is frequently pushed to operate the switch S2, 5 will not be able to withstand this operation force and will bend. Due to this bending, the operation feeling when the operation member 8 is pushed is reduced. Alternatively, the substrate 5 may be damaged by fatigue. Also, make sure that the substrate 5 withstands the operating force,
Further, in order to reduce the flexure of the substrate 5 when the operation member 8 is pushed, the number of columns 6 connecting the panel 2 and the substrate 5 is increased, or the columns 6 are not arranged close to the switch S2. Therefore, the mounting of electronic components other than the switch S2 on the substrate 5 is restricted, and the mounting work of the substrate 5 becomes complicated.

The present invention solves the above-mentioned problems of the prior art. It is possible to increase the rigidity of the extension portion of the resin panel, and the substrate provided inside the extension portion is less likely to bend and fatigue. It is an object of the present invention to provide an in-vehicle electronic device that is made difficult.

Is formed on the housing-side base of the metal support (boundary between the metal support and the housing) in the panel direction so as to bypass the boundary wall between the first space and the second space. The concave portion is bent in a concave shape.

In the above, when a board having the operation component mounted on the surface is interposed between the extension of the panel and the metal support, the back surface of the board is supported by the metal support. It is preferable. That is, the substrate is directly supported by the metal support, or an elastic support is attached between the back surface of the substrate and the metal support, and the substrate is supported by the metal support via the support. Alternatively, a support body that supports the substrate from the back side may be integrally formed on the inner surface of the bottom plate of the box-shaped metal support body so as to integrally project.

Further, the housing is composed of a metal chassis having a din size and a metal front side plate attached to the metal chassis, and the metal support is integrally formed with the front side plate. Is preferred. Here, the din size is 182 mm in width x 175 mm in depth x 53 in height
It means a 1-din size with a dimension of mm, or a 2-din size in which only the height is twice the 1-din size.

[0012]

In the above means, since the extension formed on the resin panel is fixed to the metal support extending from the metal housing, the panel extension is reinforced by the metal support. Even when an external force acts on the extension portion when the electronic device is attached to or removed from the vehicle interior, the panel is not damaged. In the case where a first space portion in which the housing is embedded and a second space portion in which the metal support such as a box shape is embedded are formed in the mounted portion in the vehicle compartment, the metal support is on the housing side. By forming a recess in the base that bypasses the boundary wall between the first space and the second space, the metal support can be attached in close contact with the console panel of the automobile. , The appearance of the panel in the mounted state and the appearance at the mounting boundary between the console panel and the panel are not impaired.

Further, if the substrate on which the operating member such as a switch provided inside the extension portion of the panel is mounted is supported from the back side by the metal support, it is provided in the panel extension portion. The operation force of the operation member such as the push button can be received by the metal support, and the bending of the substrate and the fatigue of the substrate can be prevented.

Furthermore, if the housing is composed of a metal chassis having a din size width and a metal front plate, and a metal support is integrally formed on the front plate, the din size housing and the housing The semi-finished product in which various mechanisms are incorporated can be used also as the vehicle-mounted electronic device having the almost din size panel without the extension portion, and the device can be generalized.

The metal chassis 21 of the housing 20 of the electronic device is embedded in the first space 11a, and the box-shaped metal support D extending laterally from the housing 20 is the second chassis of the console panel 11. It is embedded in the space 11b. The back surface of the panel 40 is installed in close contact with the panel surface (surface of the attached portion) 11c of the console panel 11.

It should be noted that the attached space, that is, the console panel 11, has a first space 11a and a second space 11b.
A boundary wall 11d, which is a boundary portion with, extends to a position substantially flush with the panel surface 11c.

Will bypass the boundary wall 11d. As a result, the console panel 11 which is the attached portion has the first space 11
Even if the boundary wall 11d between the a and the second space portion 11b is present, the panel 40 can be installed without being largely lifted from the panel surface 11c of the console panel 11, and the appearance when the electronic device is installed is good. become. That is, the metal support D for reinforcing the extension operation part B of the panel 40.
However, even if the metal support D and the casing 20 are integrally extended from the casing 20, the boundary E between the metal support D and the casing 20 is
1. It does not hinder the installation of the panel 40 in 1.

This on-vehicle electronic device includes a metal chassis 21.
A product obtained by integrally assembling the front plate 22, the central board 30, the board 31, and the panel 40 is treated as a finished product, and the above-mentioned members are integrated into the console panel 1
1 and is taken out from the console panel 11 as an integral body during maintenance work. Even when a large external force is applied to the extension operation portion B of the panel 40 during the assembling or removing work, the extension operation portion B
Is reinforced by the metal support D, the panel 40
Does not cause problems such as damage. Further, in FIG. 2, when the operating body 47 is operated and the movable portion of the switch S2 is pressed, the operating force F that acts on the switch S2.
Are received by the bottom plate 22h of the metal support D via the substrate 31 and the support 32. Therefore, unlike the conventional example shown in FIG. 4, the substrate 31 does not largely bend, and the operating body 47

A recess 21d that bypasses the boundary wall 11d of the console panel 11 is formed at a boundary E between the extension 21c that constitutes the metal support D and the side plate 21b of the metal chassis 21. Thus, the metal support D can be integrally formed on either the front side plate 22 or the metal chassis 21. However, in consideration of versatility for mounting on other vehicle types, it is preferable that the metal support D is formed integrally with the front side plate 22. That is, if a din size front plate and a panel are prepared instead of the front plate 22 and the panel 40 and attached to the metal chassis 21, the metal chassis 21 and the metal chassis 21 are built in the metal chassis 21 as products for which only the din size panel can be installed. It is possible to use various mechanisms as they are.

The metal support D is attached to the metal chassis 21.
It is also possible to manufacture it separately from both the front plate 22 and the front plate 22, and fix the metal support D to the side plate 21b of the metal chassis 21 or the front plate 22 by means such as screwing. Also, the substrate 30 or 31
The operation component mounted on may be a variable resistor or the like in addition to the switches S1 and S2.

[0033]

As described above, according to the present invention, since the resin panel extending laterally of the housing is reinforced by the metal support extending from the housing, the extension portion of the panel is subjected to an external force during assembly or maintenance work. Will not be damaged by.

If the substrate installed inside the extended portion of the panel is supported by the metal support, the substrate will not be bent or fatigued by the operating force applied to the operating parts such as the switch.

Furthermore, by forming the housing from the metal chassis and the front side plate and forming the metal support integrally with the front side plate, the metal chassis can be used for other models and the versatility is increased.
