Description

本発明は、例えば、回転指示用の目盛板の中央に、ＬＣＤなどの表示器を配置した表示装置に用いられる指針及び当該指針を用いた表示装置に関するものである。   The present invention relates to a pointer used in a display device in which a display device such as an LCD is disposed in the center of a rotation instruction scale plate, and a display device using the pointer.

上述した表示器として、例えば、通常の回転指示用の目盛板の正面側に、表示器を配置するものが考えられている。このような配置とすれば、指針によって表示器の視認が邪魔されることなく、目盛板の中央に表示器を配置することができる。   As the display described above, for example, a display that is arranged on the front side of a normal rotation instruction scale plate is considered. With such an arrangement, the indicator can be arranged in the center of the scale plate without disturbing the visual recognition of the indicator by the pointer.

しかしながら、目盛板が例えば車速などの重要な情報を表示し、表示器が現在時刻などの比較的重要でない情報を表示するような場合など、目盛板を表示器より正面側に配置して、目盛板の視認性をより高めたいという要望があった。   However, if the scale plate displays important information such as the vehicle speed, and the display unit displays relatively unimportant information such as the current time, the scale plate is placed on the front side of the display unit. There was a request to improve the visibility of the board.

そこで、このような要望に応えるため、図３に示すようなものが提案されている（特許文献１）。図３（ａ）は、従来の表示装置の一例を示す正面図であり、図３（ｂ）は、図３（ａ）の表示装置のＩＩＩ−ＩＩＩ線断面図である。同図に示すように、表示装置は、ディスプレイ１１と、このディスプレイ１１の正面側に配置される目盛板１２とを備えている。この目盛板１２には、目盛１２ａに沿った略円弧状のスリット１２ｂが設けられている。   Therefore, in order to meet such a demand, the one shown in FIG. 3 has been proposed (Patent Document 1). FIG. 3A is a front view showing an example of a conventional display device, and FIG. 3B is a cross-sectional view taken along line III-III of the display device of FIG. As shown in the figure, the display device includes a display 11 and a scale plate 12 arranged on the front side of the display 11. The scale plate 12 is provided with a substantially arc-shaped slit 12b along the scale 12a.

また、ディスプレイ１１の背面には、駆動部１４（図３（ｂ）参照）が設けられ、この駆動部１４により指針１５が旋回される。この指針１５は、目盛板１２の背面側に配置される第１の指針部１５ａと、目盛板の正面側に配置される第２の指針部１５ｂとから構成されている。第１の指針部１５ａと第２の指針部１５ｂとは、目盛板１２に設けられたスリット１２ｂを通じて連結されている。   In addition, a drive unit 14 (see FIG. 3B) is provided on the back surface of the display 11, and the pointer 15 is turned by the drive unit 14. The pointer 15 includes a first pointer portion 15a disposed on the back side of the scale plate 12 and a second pointer portion 15b disposed on the front side of the scale plate. The 1st pointer part 15a and the 2nd pointer part 15b are connected through the slit 12b provided in the scale plate 12. As shown in FIG.

以上の構成によれば、第１の指針部１５ａがディスプレイ１１の背面で旋回すると、第２の指針部１５ｂがスリット１２ｂに沿って目盛板１２の正面で旋回するため、指針１５がディスプレイ１１の視認を邪魔することなく、目盛板１２上の目盛１２ａを指示することができる。
ＤＥ４３２１１４６Ａ１ According to the above configuration, when the first pointer portion 15a is turned on the back surface of the display 11, the second pointer portion 15b is turned on the front surface of the scale plate 12 along the slit 12b. The scale 12a on the scale plate 12 can be instructed without disturbing visual recognition.
DE43211146A1

しかしながら、上述した従来の表示装置において、駆動部１４は、目盛板１２のすぐ背面に駆動部１４を設けることができず、ディスプレイ１１の背面に設けている。このため、指針１５は、図３（ｂ）に示すように、先端部分を屈曲形状に形成する必要があり、全長が長く、先端部分が重いものとなる。この形状では、先端の重みで指針１５がたわみ、指示誤差が生じる他、目盛板１２等との干渉などが生じ、異音の発生原因となる。   However, in the conventional display device described above, the drive unit 14 cannot be provided on the back surface of the scale plate 12 but is provided on the back surface of the display 11. For this reason, as shown in FIG.3 (b), the pointer | guide 15 needs to form a front-end | tip part in a bending shape, A full length is long and a front-end | tip part becomes a heavy thing. In this shape, the pointer 15 bends due to the weight of the tip, an instruction error occurs, and interference with the scale plate 12 or the like occurs, causing abnormal noise.

そこで、指針１５を形成する材料として、たわみにくい、固い材料を用いる必要がある。しかしながら、指針１５を形成する材料が固くなると、指針１５に設けた軸穴に、駆動部１４の軸を打ち込んで圧入する際、指針１５のクラック（割れ）や、打ち込み時の荷重超過による駆動部１４の破壊などの問題が生じてしまう。   Therefore, it is necessary to use a hard material that is difficult to bend as a material for forming the pointer 15. However, when the material forming the pointer 15 becomes hard, when the shaft of the drive unit 14 is driven into the shaft hole provided in the pointer 15 and press-fitted, the drive unit due to cracks in the pointer 15 or excessive load during driving. 14 and other problems will occur.

そこで、本発明は、上記のように問題点に着目し、指針のたわみを防止しつつ、指針に設けた軸穴に駆動部の軸を打ち込む際、指針の割れや、駆動部の破壊が発生しないようにすることができる表示装置を提供することを課題とする。   Therefore, the present invention pays attention to the problems as described above, and when the shaft of the drive unit is driven into the shaft hole provided in the pointer while preventing the deflection of the pointer, cracking of the pointer or destruction of the drive unit occurs. It is an object of the present invention to provide a display device that can be prevented from doing so.

以下、本発明の表示装置を、図面に基づいて説明する。図１は、本発明の指針及び表示装置を組み込んだコンビネーションメータの一実施の形態を示す正面図である。図２は、図１に示すコンビネーションメータのＩ−Ｉ線部分断面図である。同図に示すように、本発明の指針を用いた表示装置は、例えば、車両内のコンビネーションメータ２０内に設けられている。このコンビネーションメータには、表示装置として、スピードメータ２１と、タコメータ２２とが備えられている。   Hereinafter, the display device of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an embodiment of a combination meter incorporating the pointer and display device of the present invention. FIG. 2 is a partial cross-sectional view taken along line II of the combination meter shown in FIG. As shown in the figure, a display device using the pointer of the present invention is provided, for example, in a combination meter 20 in a vehicle. The combination meter is provided with a speedometer 21 and a tachometer 22 as display devices.

上述したスピードメータ２１は、図１に示すように、目盛板２１ａ、指針２１ｂ、表示器としての液晶ディスプレイ（ＬＣＤ）２１ｃから構成されている。目盛板２１ａは、中央に略円形の穴が設けられた正面視ドーナツ状に形成され、その外周に沿って速度目盛２１ａ１が形成されている。また、ＬＣＤ２１ｃは、目盛板２１ａの背面に配置され、目盛板２１ａに設けられた穴を通じて、正面から視認可能となっている。つまり、ＬＣＤ２１ｃが、目盛板２１ａの内周によって囲まれた形となっている。   As shown in FIG. 1, the speedometer 21 described above includes a scale plate 21a, hands 21b, and a liquid crystal display (LCD) 21c as a display. The scale plate 21a is formed in a donut shape in a front view in which a substantially circular hole is provided in the center, and a speed scale 21a1 is formed along the outer periphery thereof. Moreover, LCD21c is arrange | positioned at the back surface of the scale plate 21a, and can be visually recognized from the front through the hole provided in the scale plate 21a. That is, the LCD 21c is surrounded by the inner periphery of the scale plate 21a.

このＬＣＤ２１ｃには、例えば、ウォーニングなどが表示される。また、目盛板２１ａの内周縁と、ＬＣＤ２１ｃの外周縁との間に隙間ができず、正面から見て目盛板２１ａに設けた穴が、ＬＣＤ２１ｃ上に重なっているような構成となっている。   For example, a warning or the like is displayed on the LCD 21c. In addition, there is no gap between the inner peripheral edge of the scale plate 21a and the outer peripheral edge of the LCD 21c, and the holes provided in the scale plate 21a overlap the LCD 21c when viewed from the front.

同様に、タコメータ２２も、目盛板２２ａ、指針２２ｂ、表示器としてのＬＣＤ２２ｃから構成されている。目盛板２２ａは、中央に略円形の穴が設けられた正面視ドーナツ状に形成され、その外周に沿って回転数目盛２２ａ１が形成されている。また、ＬＣＤ２２ｃは、目盛板２２ａの背面に配置され、目盛板２２ａに設けられた穴を通じて、正面から視認可能となっている。つまり、ＬＣＤ２２ｃが、目盛板２２ａの内周によって囲まれた形となっている。   Similarly, the tachometer 22 includes a scale plate 22a, a pointer 22b, and an LCD 22c as a display. The scale plate 22a is formed in a donut shape in a front view in which a substantially circular hole is provided in the center, and a rotation speed scale 22a1 is formed along the outer periphery thereof. Moreover, LCD22c is arrange | positioned at the back surface of the scale plate 22a, and can be visually recognized from the front through the hole provided in the scale plate 22a. That is, the LCD 22c is surrounded by the inner periphery of the scale plate 22a.

このＬＣＤ２２ｃには、例えば、現在時刻などの情報が表示される。また、目盛板２２ａの内周縁と、ＬＣＤ２２ｃの外周縁との間に隙間ができず、正面から見て目盛板２２ａに設けた穴が、ＬＣＤ２２ｃ上に重なっているような構成となっている。   For example, information such as the current time is displayed on the LCD 22c. Further, there is no gap between the inner peripheral edge of the scale plate 22a and the outer peripheral edge of the LCD 22c, and a hole provided in the scale plate 22a as viewed from the front is overlapped on the LCD 22c.

次に、上述したスピードメータ２１の詳細な構成を、図２に示す断面図に基づいて説明する。同図に示すように、スピードメータ２１はさらに、ＬＣＤ２１ｃの背面に配置された駆動部２１ｄと、この駆動部２１ｄにより回転する軸としての回転軸２１ｅとを備えている。   Next, the detailed structure of the speedometer 21 mentioned above is demonstrated based on sectional drawing shown in FIG. As shown in the figure, the speedometer 21 further includes a drive unit 21d disposed on the back surface of the LCD 21c, and a rotation shaft 21e as an axis rotated by the drive unit 21d.

指針２１ｂは、上述した回転軸２１ｅが圧入される軸穴を形成する軸穴部２１ｂ１と、この軸穴部２１ｂ１以外の部分である指針部２１ｂ２とから構成されている。この指針部２１ｂ２は、上記回転軸２１ｅから、ＬＣＤ２１ｃの背面沿いに、回転軸２１ｅの回転中心方向とは反対方向Ｙ１に向かい、ＬＣＤ２１ｃの外周縁を越えると、ＬＣＤ２１ｃの外周側面沿いに、正面側に向かって延在している。   The pointer 21b includes a shaft hole portion 21b1 that forms a shaft hole into which the rotary shaft 21e is press-fitted, and a pointer portion 21b2 that is a portion other than the shaft hole portion 21b1. The pointer portion 21b2 extends from the rotary shaft 21e along the back surface of the LCD 21c in the direction Y1 opposite to the rotation center direction of the rotary shaft 21e, and beyond the outer peripheral edge of the LCD 21c, along the outer peripheral side surface of the LCD 21c. Extends towards.

さらに、指針部２１ｂ２は、ＬＣＤ２１ｃの正面を越えると、ＬＣＤ２１ｃの正面と目盛板２１ａの背面との間沿いに、回転中心方向Ｙ２に向かい、目盛板２１ａの内周縁を越えると、目盛板２１ａの内周側面沿いに、正面側に向かい、目盛板２１ａの正面側を越えると、目盛板２１ａの正面沿いに、反対方向Ｙ１に向かって延在している。つまり、指針２１ｂは、目盛板２１ａとＬＣＤ２１ｃとの間で回転中心方向に折り返される略Ｓ字状の屈曲形状に形成されている。   Furthermore, when the pointer portion 21b2 crosses the front surface of the LCD 21c, the pointer portion 21b2 faces the rotation center direction Y2 along the space between the front surface of the LCD 21c and the back surface of the scale plate 21a, and exceeds the inner peripheral edge of the scale plate 21a. If it goes to the front side along the inner peripheral side and exceeds the front side of the scale plate 21a, it extends in the opposite direction Y1 along the front of the scale plate 21a. That is, the pointer 21b is formed in a substantially S-shaped bent shape that is folded back in the direction of the rotation center between the scale plate 21a and the LCD 21c.

なお、上述した軸穴部２１ｂ１は、指針部２１ｂ２より硬度の低い材料で形成されている。軸穴部２１ｂ１を形成する材料としては、例えば、ポリアセタール（ロックウェル硬さＭ９４、曲げ弾性率２．５）といった柔らかい材料が考えられる。また、指針部２１ｂ２としては、ポリメチルメタクリレート（ロックウェル硬さＭ１０１、曲げ弾性率３．３）や、環状オレフィン共重合体（曲げ弾性率３）といった固く変形しにくい材料が考えられる。   The shaft hole portion 21b1 described above is formed of a material having a lower hardness than the pointer portion 21b2. As a material for forming the shaft hole 21b1, for example, a soft material such as polyacetal (Rockwell hardness M94, flexural modulus 2.5) can be considered. Further, as the pointer portion 21b2, a material that is hard and hardly deformed, such as polymethyl methacrylate (Rockwell hardness M101, flexural modulus 3.3) or cyclic olefin copolymer (flexural modulus 3) can be considered.

また、軸穴部２１ｂ１と、指針部２１ｂ２とは、例えば、圧入、インサート成形、二色成形等により、一体に形成されている。このため、軸穴部２１ｂ１と指針部２１ｂ２とを別々に組み付ける必要がなくなり、組み付け作業が簡単となる。   The shaft hole portion 21b1 and the pointer portion 21b2 are integrally formed by, for example, press fitting, insert molding, two-color molding, or the like. For this reason, it is not necessary to separately assemble the shaft hole portion 21b1 and the pointer portion 21b2, and the assembling work is simplified.

上述した形状に指針２１ｂの指針部２１ｂ２を形成することにより、駆動部２１ｄがＬＣＤ２１ｃの背面側にあった場合でも、目盛板２１ａにスリットを設けることなく、指針２１ｂ先端がＬＣＤ２１ｃより正面側に配置された目盛板２１ａ上の目盛２１ａ１を指示することができ、意匠性の向上を図ることができる。   By forming the pointer portion 21b2 of the pointer 21b in the shape described above, even if the drive portion 21d is on the back side of the LCD 21c, the tip of the pointer 21b is arranged on the front side of the LCD 21c without providing a slit in the scale plate 21a. The scale 21a1 on the scale plate 21a that has been made can be pointed out, and the design can be improved.

しかも、このために、指針部２１ｂ２の形状が、屈曲形状に形成されてしまったとしても、指針部２１ｂ２は硬度の高い材料で形成されるため、たわむことがない。一方、軸穴部２１ｂ１は、硬度の低い材料で形成されているため、回転軸２１ｅを打ち込む際、指針２１ｂの割れや、荷重超過による駆動部２１ｄの破壊などが発生することがない。また、タコメータ２２は、スピードメータ２１と同様の構成となっており、その詳細な説明は省略する。   In addition, for this reason, even if the shape of the pointer portion 21b2 is formed in a bent shape, the pointer portion 21b2 is formed of a material having high hardness, so that it does not bend. On the other hand, since the shaft hole portion 21b1 is formed of a material having low hardness, when the rotary shaft 21e is driven, there is no occurrence of cracking of the pointer 21b or destruction of the drive portion 21d due to excessive load. Further, the tachometer 22 has the same configuration as the speedometer 21, and a detailed description thereof will be omitted.

なお、上述した実施形態では、ＬＣＤ２１ｃの背面に設けた駆動部２１ｄにより回転する回転軸２１ｅから延在する指針２１ｂの場合について説明した。しかしながら、例えば、目盛板２１ａの背面に、ＬＣＤ２１ｃを囲むリングギアを設け、このリングギアを駆動部２１ｄにより回転させると共に、このリングギアの一部から指針を延在する場合も、指針２１ｂを屈曲形状に形成する必要があるため、本発明を適用することも考えられる。   In the above-described embodiment, the case of the pointer 21b extending from the rotation shaft 21e rotated by the drive unit 21d provided on the back surface of the LCD 21c has been described. However, for example, a ring gear surrounding the LCD 21c is provided on the back surface of the scale plate 21a, and the ring gear is rotated by the drive unit 21d, and the pointer 21b is bent even when the pointer extends from a part of the ring gear. Since it is necessary to form in a shape, it is also conceivable to apply the present invention.

この場合、指針部２１ｂ２は、リングギアから、ＬＣＤ２１ｃ、２２ｃの正面と目盛板２１ａ、２２ａの背面との間を回転中心方向に向かい、目盛板２１ａ、２２ａの内周端を越えると、目盛板２１ａ、２２ａの正面を回転中心方向Ｙ２とは反対方向Ｙ１に向かって延在することとなる。また、図３について、上述した従来の表示装置に用いられる指針に、本発明を適用することも考えられる。   In this case, the pointer portion 21b2 moves from the ring gear between the front surface of the LCDs 21c and 22c and the back surface of the scale plates 21a and 22a toward the center of rotation, and exceeds the inner peripheral end of the scale plates 21a and 22a. The front surfaces of 21a and 22a extend in the direction Y1 opposite to the rotation center direction Y2. Moreover, it is also conceivable to apply the present invention to the pointer used in the conventional display device described above with reference to FIG.
