Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instrument pointer device,
In particular, when the ignition (IGN) key switch of a vehicle mounted on a vehicle such as an automobile is turned off, the instrument surface is visually recognized to be black, and when the IGN key switch is turned on, the light source is lit to indicate the instrument display surface and the pointer. The present invention relates to a so-called black-face type pointer device for measuring instruments.

[0002]

2. Description of the Related Art In the case of a black-face type instrument, the instrument unit is housed in an instrument case having a black transparent cover on the surface, and fixed to the output shaft of the instrument unit that is driven to rotate according to the measured amount. By making the pointer visible through the black transparent cover, the light source of the pointer is turned off when the IGN key switch is off, and the instrument surface is visible as black with nothing. Therefore, IGN
The pointer when the key switch is turned on must be visually recognized through the black transparent cover, and cannot be clearly recognized unless the pointer is bright with sufficiently strong luminous intensity.

Therefore, conventionally, as shown in JP-A-1-277718, the pointer itself is composed of a discharge tube,
As disclosed in JP-A-2-298818, there has been proposed a device in which a pointer is made to shine by a light emitting diode mounted thereon. In these proposals, in order to supply power to the discharge tube and the light-emitting diode of the pointer without impairing the rotation of the pointer driven by the meter unit according to the measurement amount, it is mounted on the output shaft of the meter unit. Power was supplied through all the individual mustache dances.
However, each of these has a problem that the structure is complicated, the assembling property is poor, and the manufacturing cost is increased.

Therefore, in order to prevent the manufacturing cost from increasing because the structure is simple and the assembling property is good, the applicant of the present application has previously disclosed the construction as shown in FIG. 6 in Japanese Utility Model Laid-Open No. 4-1409. Proposed the pointer device. In the figure,
The pointer 2 is fixed to the upper end of the output shaft 1a of the instrument unit 1 which is driven to rotate in accordance with the measured amount, and the light source 3 which emits light for introducing the pointer 2 into the indicator 2 and making the indicator 2a shine is attached to the instrument unit 1. Light source 3
The structure for supplying power can be simplified by directly supplying power to the fixed part without using any movable member. Reference numeral 4 is a dial for displaying the measured amount in cooperation with the indicator 2a of the pointer 2 driven by the instrument unit 1, and is arranged between the instrument unit 1 and the pointer 2.

[0005]

However, in the pointer device of this proposal, the light emitting portion 3a of the light source 3 is formed into a cylindrical shape by molding a plurality of light emitting diode chips 3b by resin molding, and each light emitting diode chip 3b is formed. Is radiated in the outer radial direction of the cylindrical light emitting portion 3a. On the other hand, in the pointer 2, a light introducing hole 2c is formed in a pointer cap 2b covering a portion fixed to the output shaft 1a, and the light emitting portion 3a of the light source 3 is inserted in the light introducing hole 2c, and a light emitting diode is formed. Light from the light emitting portion 3a emitted in the outer radial direction when the chip 3b is turned on is introduced into the indicating portion 2a.

Therefore, no matter how large the area of the light receiving end surface of the indicator 2a facing the outer peripheral surface of the light emitting portion 3a is in the pointer cap 2b, the thickness of the indicator 2a is extremely thin outside the pointer cap 2b. Therefore, the light received by the light-receiving end face cannot be efficiently guided to the tip of the indicator 2a, and the structure for supplying power to the light source 3 is simple, but the pointer should shine with sufficient luminous intensity. However, there is a problem that it cannot be effectively applied as a pointer device of a black face type meter.

In order to solve such a problem, the light from the light source 3 arranged above the meter unit 1 is externally introduced into the pointer 2 fixed to the output shaft 1a of the meter unit 1 so that the pointer 2 is bright. It is possible to let them do it. However, when configured in this way, the light from the light source 4
It leaks from the gap between the pointer and the pointer 2, and the light that leaks causes the area other than the pointer, which should not shine, to dimly illuminate in a ring shape, which is visible with the pointer through the black transparent cover. Problems will come up.

Further, the pointer 2 is made of a colorless transparent resin in order to make it bright and bright, but when the light incident from the outside through the black transparent cover is reflected on the surface of the pointer 2 when the IGN key switch is off. There is also a problem that the reflected light becomes visible to the driver through the black transparent cover.

Further, in the case of the above-mentioned structure, the entire light source is located below the dial plate, and thus a large space is required between the instrument unit 1 and the dial plate 4. Therefore, it is conceivable to dispose the light source 3 above the instrument unit 1 as close as possible. However, by doing so, the beard zero dance 1b for zeroing and the printed circuit board 3 attached to the output shaft 1a of the instrument unit 1
The soldering portion of the lead terminal of the light emitting portion 3a of the light source 3 which is soldered to c approaches, and the beard 1c shakes due to external vibration or the like to come into contact with the soldering portion to cause a short circuit, which causes the normal function of the instrument unit. Since there is a high risk of causing problems such as loss of fire and ignition, another problem that impairs the safety and miniaturization of the instrument will occur.

Therefore, in view of the above-mentioned conventional problems, the present invention has a simple structure for supplying power to a light source for shining a pointer, is excellent in assemblability, and can shine the pointer with a sufficiently strong luminous intensity. Moreover, it is a first object of the present invention to provide a pointer device for an instrument that can be effectively prevented from visually recognizing an extra portion other than the pointer and that can be effectively applied to a black face type instrument.

In view of the above problems, the present invention prevents the pointer from being visually recognized through the black transparent cover even if external light enters through the black transparent cover when the pointer is not bright. The second object is to provide the pointer device of

Further, in view of the above-mentioned conventional problems, the present invention further provides a pointer device for an instrument, which can achieve the first object without deteriorating the safety and downsizing of the instrument. The purpose is.

[0013]

SUMMARY OF THE INVENTION In order to achieve the first object, a pointer device for a meter, which is made according to the present invention, accommodates the meter unit in a meter case in which a black transparent cover is provided in a surface opening. Then, the pointer is fixed to the output shaft of the instrument unit that is driven to rotate according to the measurement amount, and the light from the light source arranged above the instrument unit is introduced to make the pointer shine, and the light source and the pointer. In the pointer device of the instrument, which displays the measured amount in cooperation with the letters and scales of the dial placed between the and the black transparent cover, the portion other than the pointer indicating portion is covered. In addition to forming a flange portion along the surface of the dial plate on the outer peripheral portion of the pointer cap, a ring-shaped light-shielding portion that stands up from the dial plate to the inside of the pointer cap is provided. .

In order to achieve the above-mentioned second object, the pointer device of the instrument according to the present invention is characterized in that unevenness is formed on the upper surface of the indicator portion of the pointer.

In order to achieve the above-mentioned third object, the pointer device for a meter, which is made according to the present invention, has a printed circuit board to which a lead terminal of the light source is soldered, and a zero-setting device attached to the output shaft of the meter unit. The feature is that a resin sheet is placed between the beard and Zenmai.

[0016]

With the above structure, since the ring-shaped light-shielding portion is erected from the dial to the inside of the pointer cap, the light-shielding portion restricts light obliquely incident from the light source into the pointer cap. Become. Also, since the flange part along the surface of the dial plate is formed on the outer peripheral part of the pointer cap covering the part other than the indicator part of the pointer, even if there is light that exceeds the light shielding part, this light And is attenuated during repeated reflections between the dial and the surface of the dial. Therefore, even if light leaks to the outside of the pointer cap, it will not be sufficient to make the peripheral portion shine in a ring shape.

Further, since the projections and depressions are formed on the upper surface of the pointer portion, when the pointer is not bright, the light incident through the black transparent cover is irregularly reflected by the projections and depressions to weaken the light reflected by the pointer. Therefore, the pointer is prevented from being visually recognized through the black transparent cover.

Furthermore, the resin sheet electrically insulates the soldering of the light source from the beard for zeroing mounted on the output shaft, so that even if the beard is shaken by external vibration, it will contact the soldered portion. There is nothing to do. Furthermore, the unevenness provided on the upper surface of the pointing portion allows the pointer to shine brighter.

The openings 14a ₁ and 14b ₁ for allowing the light emitted by 3a to enter the opening of the pointer cap 12b of the pointer 12 are formed in such a size as to be hidden by the pointer cap 12b.

The dial main body 14a and the light diffusion plate 14b.
A ring-shaped light-shielding member 14c standing upright from the dial 14 to the inside of the pointer cap 12b of the pointer 12 is fitted into the openings 14a ₁ and 14b ₁ of the light source holding member 13b of the pointer illumination light source unit 13. When the light diffusing plate 14b is fixed to the light diffusing plate 14b, the light source holding member 13b and the light diffusing plate 14b fix the light diffusing plate 14b by sandwiching the peripheral portion thereof, so that the light diffusing plate 14b is attached to the dial plate 14.

Characters, scales 14a ₂ and the like as shown in FIG. 4 are printed on the dial main body 14a for displaying the speed in cooperation with the pointer 12 driven by the instrument unit 11 according to the speed. Light from the dial plate light source 15 diffused by the diffuser plate 14b is applied to the back surface of the dial plate body 14a, so that the characters, the scale 14a _{2 and the} like are transmitted by the light. Be shined.

As shown in FIG. 1, the printed circuit board 13c and the dial plate light source 15 are supplied with power to turn on the light source 13a and the dial plate light source 15 by turning on the IGN key switch. Lead wires 13e and 15a drawn from the outside are respectively connected.

Reference numeral 19 is a fuel gauge disposed adjacent to the left side of the speedometer, and although the description is omitted, the structure of the pointer and dial is substantially the same as that of the speedometer. Reference numeral 20 denotes an integrating distance meter disposed below and adjacent to the speedometer, which is composed of a light emitting display such as a fluorescent display tube.

With the above configuration, the IGN key switch is

Then, the opening 12b of the pointer cap 12b
Of the light that is incident on the portion other than the light receiving portion 12a ₃ of the pointer main body 12a from ₃ in particular, the light that is incident in an oblique direction is reflected in the pointer cap 12b, as shown by the dotted line in FIG. Further, the light is repeatedly reflected on the surface of the dial 14 and tries to leak out of the pointer cap 12b through a gap between the pointer cap 12b and the surface of the dial 14. However, the ring-shaped light-shielding member 14c fitted into the openings 14a ₁ and 14b ₁ of the dial main body 14a and the light diffusion plate 14b causes the dial cap 14 of the dial 12 to move to the pointer cap 1 of the pointer 12.
Since it stands up to the inner side of 2b, the reflected light that leaks to the outside beyond the light shielding member 14 is limited.

Even if there is light that has passed through the light shielding member 14c, this light is repeatedly reflected between the flange portion 12b ₂ formed on the peripheral portion of the pointer cap 12b and the surface of the dial plate 14. Since it is attenuated, it does not cause the peripheral part to shine like a ring.

On the other hand, the light emitted from the light source 15 for illuminating the dial is diffused by the light diffusing plate 14b and is applied to the back surface of the dial main body 14a, and this illuminating light is transmitted through the characters of the dial main body 14a and the scale 14a _2. Then, when reaching the surface, letters, scale 14a _2, etc. are shined.

Therefore, the driver passes the shining indicator 12a ₁ of the pointer 12, the letters on the dial 14 and the scale 14a ₂ through the black transparent cover 18 to the indicator 12a _{1 of the} pointer 12.
The display design as shown in FIG. 5 can be visually recognized in which extra parts other than the characters and the scale 14a ₂ are not visible. As can be seen by comparing the displays of FIGS. 4 and 5 in which the black transparent cover 18 is omitted, the extra hands such as the pointer cap 12b that is not bright are not visible.

When the IGN key switch is turned off, the eight light sources 13a of the pointer illumination light source unit 13 are
And the light source 15 for illuminating the dial are turned off, and the indicator 12a
_{Since 1} and characters, the scale 14a _{2 and the} like are not illuminated, the driver visually recognizes the black surface of the black transparent cover 18, and a black-face type instrument can be obtained. Moreover, even if the external light through the time black transparent cover 18 reaches the upper surface of the indicator 12a ₁ of the pointer 12 enters into the instrument case 17, the upper surface of the indicator 12a ₁ irregularities 1
Since the incident light is diffusely reflected and weakened by 2a ₇ , the visibility of the pointer indicating portion 12a ₁ through the black transparent cover 18 when the IGN key switch is turned off is reduced.

Further, the resin sheet 13f is arranged between the soldering surface of the printed circuit board 13c of the pointer illumination light source unit 13 and the zero-removing mustache beam 11c attached to the output shaft 11b of the instrument unit 11 to electrically connect them. Even if the light source unit 13 for pointer illumination is arranged close to the upper part of the instrument unit 11, since it is electrically insulated, it will come into contact with the soldering part of the printed circuit board 13c even if the beard 11c shakes due to external vibration. You can get a safe and small instrument because it will not cause short circuit.

[0043]

As described above, according to the present invention, since the light source is arranged on the upper part of the instrument unit, the structure for supplying power to the light source of the light source unit is as simple as the conventional one, and is assembled. The property is also good.

Further, even if the light leaking to the outside of the pointer cap is limited and attenuated and the light leaks to the outside of the pointer cap, the light is temporarily leaked to the outside of the light pointer cap in a ring shape around its periphery. However, since it will not be enough to make the peripheral part shine in a ring shape, it is possible to reliably prevent the extra part other than the pointer from being visually recognized, which can be effectively applied to the black face type instrument. The pointer device can be obtained.

Further, since the light incident through the black transparent cover is diffusely reflected by the unevenness of the upper surface of the pointing portion and weakened, even if outside light is incident through the black transparent cover when the pointer is not shining, it is black transparent. The effect that the hands are prevented from being visible through the cover is obtained.

Furthermore, even if the whole beard shakes due to external vibration, it does not come into contact with the soldering portion, so that the safety and miniaturization of the instrument are not impaired.
