In the following description, the viewer side viewing the vehicle instrument from the front (viewing) is defined as the front side, and the counter-viewer side opposite to the viewer side is defined as the back side.

  1 and 2, the vehicle instrument D according to the present embodiment includes an information display body 10 as an instrument display for displaying various vehicle information, and a circuit board 20 disposed behind the information display body 10. A resin case 30 placed on the circuit board 20 so as to hold the information display body 10, a turning member 40 for defining a visible region of the information display member 10, and a see-through panel 50 covering the turning member 40. And a sounding body 60 as a functional component electrically connected to the circuit board 20 and a housing 70 provided on the back side of the circuit board 20 (information display body 10).

  For example, a TFT-type liquid crystal display panel in which a backlight including a light source is incorporated can be applied to the information display body 10. In the display area (not shown) of the information display body 10, an information display unit 11 including, for example, vehicle speed information and travel distance information is displayed as visual information. Further, the information display body 10 is electrically connected to the circuit board 20 using a flexible wiring board (not shown).

  As the circuit board 20, for example, a hard wiring board in which a wiring pattern is applied to a glass epoxy base material can be applied. On the circuit board 20, a control unit 21 that performs display control of the information display body 10 and sounding control of the sound generator 60, a connector 22, and circuit components (not shown) including resistors, capacitors, and the like are mounted (arranged). ) That is, this means that the control unit 21, the connector 22, and the circuit component are conductively connected to the wiring pattern. The connector 22 is mounted (arranged) on one surface portion P of the circuit board 20 on the back side of the circuit board 20.

  The resin case 30 is formed of, for example, a white synthetic resin material, and is disposed between the information display body 10 and the circuit board 20 and has a function as a holding unit that holds the information display body 10.

  The facing member 40 is formed of, for example, a black synthetic resin material, and has an opening window 41 for exposing the display area of the information display body 10.

  The see-through panel 50 is formed of a light-transmitting synthetic resin material, and is fixed to the turning member 40 using appropriate fixing means such as hook fixing so as to close the front opening of the opening window 41.

  For the sounding body 60, for example, a sounding element such as a speaker or a buzzer having a function of emitting a sound of sound (hearing information) can be applied, and the sounding body 60 is electrically connected to the circuit board 20. For example, the sounding body 60 having a function (predetermined function) for generating a sound as described above includes a wiring 62 having a mating connector 61 that is the mating connector 22, and the mating connector 61 is connected to the circuit board 20. The sounding body 60 is electrically connected to the circuit board 20 by being attached to the connector 22 mounted on the circuit board 20.

  The housing 70 is a resin back cover made of, for example, a white synthetic resin material, and covers a substantially flat housing body 71 that covers the back side of the circuit board 20 and the side of the circuit board 20. The side wall part 72 and the cover part 73 which can be opened and closed are provided.

  The housing main body 71 has a protruding portion 71a protruding rearward at a predetermined position P1 corresponding to the position where the sounding body 60 is disposed, and a rear side (protruding portion) at another position P2 different from the predetermined position P1. A plurality of (for example, three) extending portions 71b extending in the same direction as the protruding direction of 71a (see FIGS. 3 and 4).

  The protruding portion 71a is a substantially cylindrical cup-shaped bulging portion that bulges from the substantially flat bottom surface Y of the housing main body portion 71 toward the rear side, and is a cylindrical shape configured as an outer peripheral wall of the bulging portion. A portion 71c, an annular plate portion 71d extending inwardly behind the cylindrical portion 71c, and a position one step lower than the annular plate portion 71d, constituting the bottom wall of the bulging portion And an elastic piece 71g having a claw portion 71f for fixing the sounding body 60 with a hook.

  The bottom portion 71e is provided with a plurality of slit-like sound emitting holes H configured to allow a sound generated from the sounding body 60 to pass therethrough. Here, for example, when the control unit 21 detects that the remaining amount of fuel in the fuel tank mounted on the vehicle is small, the remaining fuel amount warning display (not shown) indicating that the remaining amount of fuel is small is shown. A sounding body is executed so that a sound effect (sound) such as “pawn” is generated from the sounding body 60 while the information display body 10 is displayed and operated so that a warning mark) is displayed as the information display unit 11. A process of blowing 60 is performed. The sound effect emitted from the sounding body 60 passes through the sound emission hole H and reaches the outside of the housing 70, so that the viewer (listener) can hear the sound effect.

  Further, three elastic pieces 71g are provided at substantially equal intervals on the peripheral edge of the bottom 71e, and extend from the peripheral edge toward the front side. And the claw part 71f is each provided in the front end side (front side) of the elastic piece 71g.

  The claw portion 71 f configured as described above is configured to be able to bend and deform along the plate surface direction of the circuit board 20. Each inclined surface 71h made of a tapered surface provided at the lower portion of each claw portion 71f is hooked and fixed to a claw receiving portion 63 provided on the outer peripheral portion of the sounding body 60. In addition, 71i is a support part integrally formed with the bottom part 71e in order to support the back surface side periphery of the sounding body 60. As a result, the sounding body 60 is sandwiched between the support portion 71 i and the three claw portions 71 f, and the drop-off from the housing main body portion 71 is suppressed.

  On the other hand, the extending portion 71b is provided at another position P2, which is a position different from the predetermined position P1. The other position P2 here refers to three positions shown in FIG. 4 as an example. Specifically, the upper center portion of the housing body 71 and the lower left corner of the housing body 71 are shown. And the lower right corner of the casing body 71. Each of the extending portions 71b has substantially the same height dimension (second projecting height dimension described later), and extends from the housing body 71 (bottom surface Y) to the rear side (second end portion described later). It is substantially L-shaped so as to have an extending leg 71j and an extending portion 71k extending along the plate surface direction of the circuit board 20 (starting from the second end portion).

  Here, the first projecting height dimension S1 of the projecting portion 71a from the housing main body portion 71 (bottom surface Y) and the second projecting height of the extending portion 71b (that is, the leg portion 71j) from the housing main body portion 71. When attention is paid to the magnitude relationship with the dimension S2, the second protrusion height dimension S2 is set to be larger than the first protrusion height dimension S1. In other words, this means that the first end portion B1 of the protrusion 71a located at a position away from the housing body 71 (bottom surface Y) is an extended portion located at a position away from the housing body 71 (bottom surface Y). It means that it is located in front of the second end portion B2 of 71b.

  The lid portion 73 is a hinged cover that is hingedly coupled to the housing body portion 71, and is provided at a position corresponding to the connector 22. Then, when the lid 73 is open as shown in FIG. 6, an operator who performs the assembly work of the vehicle meter D is wearing the connector 22 while visually checking the mating connector 61 of the sounding body 60. It becomes possible to do. After the mating connector 61 is attached to the connector 22, the openable / closable lid 73 is changed from the open state to the closed state, so that the connector 22, the mating connector 61, and the wiring 62 are protected. .

  As described above, in the present embodiment, the housing main body 71 has the protruding portion 71a that protrudes rearward at the predetermined position P1 corresponding to the arrangement position of the sounding body 60 and the rear side at the other position P2. The first end portion B1 of the projecting portion 71a is positioned more forward than the second end portion B2 of the extension portion 71b.

  Accordingly, when assembling the circuit board 20 or the like to the housing 70, when the housing 70 is placed on a predetermined placement surface (installation surface) 80 virtually shown in FIG. The protruding portion 71b (second end portion B2) is placed, and a gap (space) 81 is formed between the protruding portion 71a and the placement surface 80. Therefore, since the housing 70 is held horizontally on the mounting surface 80 in a stable state, not in an unstable state (fluctuating state), the assembly work to the housing 70 such as the circuit board 20 becomes easy. A vehicle instrument D capable of improving the assembly workability can be provided.

  Further, in the present embodiment, the extending portion 71b includes the leg portion 71j extending from the housing body 71 (bottom surface Y) to the second end portion B2, and the board of the circuit board 20 starting from the second end portion B2. By providing the extension portion 71k extending along the surface direction, when the casing 70 is placed on the placement surface 80, the extension portion 71k positioned at the lowermost portion of the case 70 and the placement surface 80 Since the contact area increases, there is an advantage that the housing 70 can be more stably placed on the placement surface 80.

  In addition, this invention is not limited by the above-mentioned embodiment and drawing. Changes (including deletion of constituent elements) can be added to the embodiments and the drawings as appropriate without departing from the scope of the present invention.

  For example, in the above-described embodiment, an example in which the information display body 10 is composed of an instrument display such as a liquid crystal display panel has been described. However, for example, the information display body 10 is composed of a pointer (instrument pointer) and a scale indicated by the pointer. It is good also as an analog type instrument mainly comprised from the display board (display panel for instruments) which has display parts, such as. In the case of an analog type instrument, the pointer is connected to a rotating shaft of a motor (pointer driving means) mounted on the circuit board 20 so as to drive the pointer.

  Further, in the above-described embodiment, the sounding body 60 is applied as a functional component having a predetermined function. However, as a functional component, a vehicle body mounted on one surface portion P of the circuit board 20 in addition to the sounding body 60. It may be a connector for side connection. In this case, the projecting portion 71a may be a substantially frame-shaped standing wall portion that projects from the bottom surface Y toward the rear side in a standing wall shape. The substantially frame-shaped standing wall portion surrounds the vehicle body side connection connector (for capturing an electrical input signal into the circuit board 20) when the vehicle instrument D is viewed from the back side. It becomes a hollow wall part. Further, the number of functional parts may be plural (for example, the sound generator 60 and the connector for connecting to the vehicle body). In this case, the number of the protrusions 71a should be the same as the number of functional parts.

  Further, the number of the extending portions 71b is not limited to three, but may be four or more or two. In the case where the two extending portions 71b are provided, a standing wall shape along the left end surface R1 and the right end surface R2 of the vehicle instrument D in FIG. Needless to say, the bottom surface Y of the housing main body 71 is not limited to a flat shape, and may be, for example, a shape having a step.
