Japanese Patent No. 3457142

  However, in the pointer instrument according to Patent Document 1, the rotation of the pointer and the rotation of the auxiliary scale coincide with each other.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a pointer instrument that can rotate an auxiliary index to be viewed using light reflection independently of the pointer. .

  In order to achieve the above object, the present invention employs the following technical means.

  The pointer instrument according to claim 1 is arranged in a rotatable pointer, an arc shape or an elliptical arc shape, and has an indicator portion indicated by the pointer, a light source, and a pointer shape. A rotatable light guide pin that emits the light emitted from the light source from the tip and the indicator portion are arranged in parallel, and the emitted light from the tip portion of the light guide pin is reflected to the viewing side to assist the indicator portion. And a reflecting portion to be visually observed as an auxiliary index to be performed, and the tip portion of the light guide pin is configured to be rotatable inside the reflecting portion.

  In this configuration, the light guide pin causes the light emitted from the light source to be emitted from the tip portion, and the light emitted from the tip portion is reflected by the reflecting portion to the viewing side, and is viewed as an auxiliary index. Thereby, an auxiliary | assistant parameter | index can be visually observed using reflection of light. Moreover, in this structure, the front-end | tip part of a light guide pin is comprised so that rotation inside a reflection part is possible. Thereby, irrespective of the rotation position of the light guide pin, the emitted light from the tip can be guided to the reflection part. Therefore, the auxiliary indicator to be viewed using the reflection of light can be viewed by rotating the light guide pin.

  In this configuration, the auxiliary indicator can be rotated independently of the pointer by rotating the light guide pin independently of the pointer.

  As a result, it is possible to provide a pointer instrument that can rotate the auxiliary index to be visually observed using the reflection of light independently of the pointer.

  The pointer instrument according to claim 2 is characterized in that the rotation axis of the light guide pin is coaxial with the rotation axis of the pointer. As a result, the light emitted from the light guide pin in the circumferential direction from the rotation axis of the pointer is reflected by the reflecting portion to the viewing side and is viewed as an auxiliary index. For this reason, the auxiliary index is visually inspected in a direction from the rotation axis of the pointer toward the circumference. Therefore, the function of the auxiliary indicator that assists the indicator portion can be enhanced.

  The pointer instrument according to claim 3 is characterized in that the light guide pin is arranged behind the pointer. Thereby, it becomes possible to take the structure which covers a light guide pin among a light guide pin and a pointer.

  The pointer instrument according to claim 4 is characterized in that the light guide pin is fixed at a rotation position representing a predetermined reference value. As a result, the auxiliary index representing the reference value and the pointer indicating the index portion can be associated with each other and viewed, and the information can be displayed easily.

  In the pointer instrument according to claim 5, the light guide pin is disposed behind the pointer, and the light guide pin is rotated at the same speed as the pointer while overlapping the light guide pin so as to hide the light guide pin. It is made to move. Thereby, the light guide pin is concealed, and the auxiliary index can be rotated at the same speed and at the same position as the pointer. For this reason, it is possible to emphasize and display the rotation of the pointer without viewing the light guide pin.

  The pointer instrument according to claim 6 includes a light-shielding member that is disposed between the tip portion of the light guide pin and the reflection portion and has an opening in the shape of an auxiliary index, and the reflection portion of the light guide pin that has passed through the opening. The emitted light from the tip is visually observed as an auxiliary index. For this reason, an auxiliary | assistant parameter | index can be visually recognized with various shapes by simple structure.

  The pointer instrument according to claim 7 is characterized in that the light shielding member is disposed behind the indicator portion, and the opening is disposed immediately below the indicator portion. In this configuration, since the opening is arranged immediately below the indicator portion, the auxiliary indicator is visible only at the same rotational position as the indicator portion, and is not visible at other rotational positions. Therefore, the auxiliary index that rotates in parallel with the index unit can be changed between display and non-display in correspondence with the index unit, and the rotational position relationship between the index unit and the auxiliary index is emphasized. Can be displayed.

The light from the light emitting diode 8 is guided to the viewing side through the pointer 6 according to the optical path P4, and the pointer 6 is configured to emit light. Further, a light shielding cap 61 is provided on the viewing side of the pointer 6 on the rotating shaft side so that the light emitting diode 8 is not directly exposed to the viewing side.

  The first light guide pin 62 and the light emitting diode 83 are fixed to the distal end side of the first shaft 72, and the light emitting diode 83 is electrically connected to the printed circuit board 10 via the first movement 7. The first light guide pin 62 introduces the light emitted from the light emitting diode 83 from the rotating shaft side of the first light guide pin 62 according to the optical path P3, and starts from a distal end portion 621 of the first light guide pin 62 to be described later. 1 The light is emitted to the reflecting portion 41. Further, as shown in FIGS. 1 and 2, the tip portion 621 of the first light guide pin 62 is configured to be rotatable inside the first reflecting portion 41. As a result, regardless of the rotational position of the first light guide pin 62, the light emitted from the light emitting diode 83, that is, the light emitted from the tip portion 621 can be guided to the first reflecting portion 41.

  In the present embodiment, the first movement 7 is configured to rotate the pointer shaft 71 and the first shaft 72 by an angle corresponding to the vehicle speed signal, and the first light guide pin 62 is used as the rotation axis of the pointer 6. Coaxially rotated at the same speed as the pointer 6. The first light guide pin 62 is disposed behind the pointer 6 and overlaps the first light guide pin 62 with the pointer 6 so as to conceal the first light guide pin 62 and at the same speed as the pointer 6. 1 The light guide pin 62 is rotated.

  The arc-shaped first reflecting portion 41 is arranged on the outer peripheral side of the scale portion 31 in parallel with the scale portion 31, reflects the emitted light from the tip portion 621 of the first light guide pin 62 to the viewing side, and 1 as an auxiliary indicator 33B. The first reflection portion 41 has a mirror-like reflection characteristic, and is formed on the arc-shaped third ring member 4 as an aluminum thin film, for example. The first reflecting portion 41 is inclined at approximately 45 degrees with respect to the viewing direction so that the light from the light emitting diode 83 guided by the first light guide pin 62 can be reflected to the viewing side by the first reflecting portion 41 along the optical path P3. Form. Specifically, the first reflecting portion 41 is formed on the third ring member 4 formed with the cross section inclined by 45 degrees.

  As shown in FIGS. 3 and 4, the second ring member 3 is disposed between the tip portion 621 of the first light guide pin 62 and the first reflecting portion 41 and behind the scale portion 31, and has an opening. A first opening 33 is provided. The first opening 33 is disposed immediately below the scale portion 31, and as shown in FIG. 3, the first opening 33 and the second opening 34 are formed in the second ring member 3 immediately below the scale portion 31, and are guided therebetween. The light body 32 is disposed. On the other hand, as shown in FIG. 4, the first opening 33 and the second opening 34 are not formed in the second ring member 3 without arranging the scale portion 31 and the light guide 32 in a portion that is not directly below the scale portion 31.

  Immediately below the scale portion 31, as shown in FIG. 3, the emitted light from the tip portion 621 of the first light guide pin 62 and the second opening 34 formed in the second ring member 3 along the optical path P3. The light guide 32 guides the first reflector 41 through the first opening 33. The first opening 33 has the shape of the first auxiliary indicator 33B shown in FIG. 1, and the light emitted from the tip 621 of the first light guide pin 62 transmitted through the first opening 33 is the first auxiliary indicator 33B. An auxiliary index image 33A having a shape is formed. The first reflecting portion 41 reflects the light of the auxiliary index image 33 </ b> A to the viewing side and causes the light to be viewed as a first auxiliary index 33 </ b> B (virtual image) that assists the scale portion 31.

  For this reason, it becomes possible to make the 1st auxiliary | assistant parameter | index 33B visible visually by various shapes with the simple structure of the 1st opening 33. FIG.

  On the other hand, in the portion that is not directly under the scale portion 31, that is, in the lower portion between the scale portion 31 and the scale portion 31, the emitted light from the tip portion 621 of the first light guide pin 62 is as shown in FIG. According to the optical path P5, the light is shielded by the second ring member 3 and is not guided to the first reflecting portion 41. For this reason, the first auxiliary index 33B is not visually observed.

  As a result, in FIG. 1, the first auxiliary indicator 33 </ b> B is visible when the pointer 6 indicates the scale portion 31, but the first auxiliary indicator 33 </ b> B is visible, but the pointer 6 does not indicate the scale portion 31. In other words, when the pointer 6 indicates between the scale portion 31 and the scale portion 31, the first auxiliary index 33B is not visually observed. Accordingly, the first auxiliary indicator 33B that rotates in the same manner as the pointer 6 can display the rotation of the pointer 6 in an emphasized manner, and the first auxiliary indicator 33B that rotates in parallel with the scale unit 31 can be displayed on the scale. It is possible to change between display and non-display in correspondence with the part 31, and it is possible to emphasize and display the rotational position relationship between the scale part 31 and the first auxiliary indicator 33B. That is, it is possible to recognize the vehicle speed without paying attention to the speedometer 1 and display the vehicle speed easily.

  Further, since the first reflecting portion 41 is arranged in parallel with the scale portion 31, the first auxiliary index 33 </ b> B rotates in parallel with the scale portion 31. Thereby, the 1st auxiliary parameter | index 33B can improve the function of the 1st auxiliary parameter | index 33B which assists the scale part 31. FIG.

  The first auxiliary indicator 33B, the light emission display of the pointer 6, the light emission display of the character portion 21, and the light emission display of the scale portion 31 are configured to be viewed through the transparent cover 13. The first ring member 2, the second ring member 3, the third ring member 4, and the first case 9 are fixed to each other by an adhesive, hooking, welding, or the like. The cover 13 is fixed to the second case 12.

  As shown in FIG. 5, a speed sensor 14 that detects the vehicle speed of the automobile is connected to the control device 11 that includes a microcomputer or the like so that the signal can be input. The first movement 7 controlled by the control device 11 and the light emitting diodes 8, 81-83 are connected to the control device 11.

  The operation of the speedometer 1 according to the first embodiment of the present invention configured as described above will be described.

  When an ignition switch (not shown) is turned on, in FIG. 5, the control device 11 detects it and starts operation. That is, the control device 11 calculates the vehicle speed based on the signal from the speed sensor 14 and controls the first movement 7 so that the pointer shaft 71 and the first shaft 72 are rotated by an angle corresponding to the vehicle speed. At this time, the control device 11 turns on the light-emitting diodes 8 and 81-83.

  In FIG. 2, the light from the light-emitting diode 82 that has turned on transmits and illuminates the character portion 21 according to the optical path P <b> 1, thereby causing the character portion 21 to emit light. Further, the light from the light-emitting diode 81 that has been turned on transmits and illuminates the scale portion 31 by illuminating the scale portion 31 according to the optical path P2, and the light from the light-emitting diode 8 that has been turned on follows the pointer 6 according to the optical path P4. Is displayed.

  When the pointer 6 and the first light guide pin 62 indicate the scale portion 31 as shown in FIG. 1 by the control of the first movement 7, the arrangement relationship shown in FIG. That is, the first light guide pin 62 introduces the light emitted from the light emitting diode 83 from the rotating shaft side of the first light guide pin 62 according to the optical path P <b> 3, and the first light guide pin 62 starts from the tip 621 of the first light guide pin 62. The light is emitted to the reflection unit 41. Light emitted from the tip 621 of the first light guide pin 62 is guided to the first reflector 41 by the light guide 32 through the second opening 34 and the first opening 33 to form an auxiliary index image 33A. The first reflecting portion 41 reflects the light of the auxiliary index image 33 </ b> A to the viewing side and causes the light to be viewed as a first auxiliary index 33 </ b> B (virtual image) that assists the scale portion 31.

  That is, the first light guide pin 62 whose tip portion 621 is rotatable inside the first reflecting portion 41 introduces light emitted from the light emitting diode 83 from the rotating shaft side, and from the tip portion 621 to the first reflecting portion. 41 is emitted. In addition, the emitted light is reflected by the first reflecting portion 41 toward the viewing side, and is viewed as the first auxiliary index 33B. Therefore, the rotatable first auxiliary indicator 33B can be viewed using light reflection.

  On the other hand, when the pointer 6 and the first light guide pin 62 do not indicate the scale portion 31 by the control of the first movement 7, that is, the pointer 6 and the first light guide pin 62 are connected to the scale portion 31 and the scale portion 31. When the interval is instructed, the arrangement relationship shown in FIG. 4 is obtained. In this case, the emitted light from the tip portion 621 of the first light guide pin 62 is shielded by the second ring member 3 along the optical path P5 and is not guided to the first reflecting portion 41. For this reason, the first auxiliary index 33B is not visually observed.

  As a result, as shown in FIG. 1, when the pointer 6 indicates the scale portion 31, the first auxiliary indicator 33 </ b> B is visually observed, but the pointer 6 indicates the scale portion 31. When not doing, that is, when the pointer indicates between the scale part 31 and the scale part 31, the first auxiliary index 33B is not visually observed. That is, since the first auxiliary indicator 33B is changed between display and non-display in correspondence with the scale portion 31, the rotational positional relationship between the scale portion 31 and the first auxiliary indicator 33B can be emphasized and displayed.

  Accordingly, the first auxiliary indicator 33B that rotates in the same manner as the pointer 6 can display the rotation of the pointer 6 in an emphasized manner, and emphasize the rotational position relationship between the scale portion 31 and the first auxiliary indicator 33B. Can be displayed. Therefore, the vehicle speed can be recognized without paying attention to the speedometer 1, and the vehicle speed can be easily recognized.

  Further, since the first reflecting portion 41 is arranged in parallel with the scale portion 31, the first auxiliary index 33 </ b> B rotates in parallel with the scale portion 31. Thereby, the 1st auxiliary parameter | index 33B can improve the function of the 1st auxiliary parameter | index 33B which assists the scale part 31. FIG.

  Further, since the first light guide pin 62 is rotated at the same speed and at the same position as the pointer 6 behind the pointer 6, the rotation of the pointer 6 is emphasized and displayed without observing the first light guide pin 62. it can.

  In addition, the simple configuration of the first opening 33 allows the first auxiliary index 33B to be visually observed in various shapes.

  Further, since the rotation axis of the first light guide pin 62 is coaxial with the rotation axis of the pointer 6, in FIG. 1, the rotation axis of the pointer 6 extends in the circumferential direction, that is, from the rotation axis of the pointer 6 to the pointer 6. The light emitted from the first light guide pin 62 along the direction in which the first light guide pin 62 extends is reflected by the first reflecting portion 41 toward the viewing side so as to be viewed as the first auxiliary index 33B. For this reason, the first auxiliary indicator 33B is viewed in a tilted direction from the rotary shaft of the pointer toward the circumference, that is, tilted in a direction in which the pointer 6 extends from the rotary shaft of the pointer 6. For example, when the pointer 6 and the first light guide pin 62 indicate the scale portion 31 corresponding to the character portion 21 of the number “40”, the first auxiliary index 33B is visually observed with the same inclination as the scale portion 31. Can be made. Therefore, the function of the first auxiliary index 33B that assists the scale portion 31 can be enhanced.

  In the above-described example, the pointer 6 and the first light guide pin 62 are rotated in conjunction with each other. However, since the first movement 7 can rotate the pointer shaft 71 and the first shaft 72 independently of each other, The first auxiliary index 33B can be rotated independently of the pointer 6. Thereby, as described later, the present invention can be applied to various uses.

  The speedometer 1 which is the pointer instrument according to the first embodiment of the present invention described above includes a rotatable pointer 6 and an indicator portion which is arranged in one of an arc shape and an elliptical arc shape, and the pointer 6 indicates. A certain scale part 31, a light emitting diode 83 as a light source, and a first light guide pin that has a pointer shape and is a rotatable light guide pin that emits light emitted from the light emitting diode 83 from the tip part 621. 62 and a first auxiliary indicator 33B that is an auxiliary indicator that assists the scale 31 by reflecting the emitted light from the tip 621 of the first light guide pin 62 to the viewing side. And a first reflecting portion 41 that is a reflecting portion to be visually observed, and a tip portion 621 of the first light guide pin 62 is configured to be rotatable inside the first reflecting portion 41.

  Accordingly, it is possible to provide a pointer instrument that can rotate an auxiliary index that is visually observed using reflection of light independently of the pointer.

When the positions are different, the first light guide pin 62 cannot be covered with the pointer 6. For this reason, among the first light guide pins 62 and the pointers 6, a light shielding portion 35 that covers the first light guide pins 62 is provided. As shown in FIG. 7, the light shielding portion 35 is formed integrally with the second ring member 3 by resin molding.

  In addition, the structure which makes the 1st reflection part 41 reflect in the viewing side according to the optical path P3, and make the emitted light from the 1st light guide pin 62 visually as 1st auxiliary | assistant parameter | index 33B is the same as that of 1st Embodiment. Therefore, this description is omitted.

  The speedometer 100 includes a liquid crystal display 15, and as shown in FIG. 6, the liquid crystal display 15 digitally displays the ACC set value on the upper side and digitally displays the vehicle speed indicated by the pointer 6 on the lower side. As shown in FIG. 7, the liquid crystal display 15 is arranged behind the printed circuit board 10, and allows each digital display of the ACC set value and the vehicle speed to be viewed through an opening (not shown) formed in the printed circuit board 10 and the light shielding portion 35. .

  As described above, since the first movement 7 can rotate the pointer shaft 71 and the first shaft 72 independently of each other, the control device 11 controls the first movement 7 to control the pointer shaft 71 and the first shaft 72. The shafts 72 are independently rotated. Specifically, the first shaft 72 is rotated and fixed so that the first light guide pin 62 is fixed at the rotation position representing the ACC setting value, and the pointer shaft 71 is rotated based on the signal from the speed sensor 14. Move.

  The second light guide pin 63 introduces the light emitted from the light emitting diode 84 from the rotation axis side and emits the light from the tip portion 631 to the second reflection portion 51, and the second reflection portion 51 is provided with the second light guide pin 63. The emitted light from the tip portion 631 is reflected to the viewing side, and is viewed as the second auxiliary index 51A for assisting the scale portion 31.

  Thus, in addition to the first auxiliary index 33B that highlights and displays the rotation of the pointer 6 as in the first embodiment, the ACC set value is visually observed as the second auxiliary index 51A as in the second embodiment. Can do.

  The first reflecting portion 41 can be configured to visually observe the first auxiliary indicator of the real image, and conversely, the second reflecting portion 51 can be configured to visually observe the second auxiliary indicator of the virtual image. It is. In this case, the first reflecting portion 41 is formed as, for example, a coating film in which fine glass powder is kneaded with a transparent resin material, and the second reflecting portion 51 is made of, for example, an aluminum thin film so as to have a specular reflection characteristic. Form.

  In the above example, the pointer 6 and the first light guide pin 62 are rotated in conjunction with each other. However, the second movement 16 independently connects the pointer shaft 71, the first shaft 72, and the second shaft 73. Since it can rotate, the pointer 6, the first auxiliary index 33B, and the second auxiliary index 51A can be rotated independently of each other. That is, both the first auxiliary index 33B and the second auxiliary index 51A that can be rotated independently of each other can be rotated independently of the pointer 6. Thereby, the present invention can be applied to various uses.

  As shown in FIGS. 8 and 9, the second light guide pin 63 is configured to be visually observed. However, as a light guide member that itself does not emit light, such as an optical fiber, a configuration that is hardly visible is also possible. .

(Fourth embodiment)
Unlike the embodiment described above, the speedometer 300 according to the present embodiment employs a configuration in which the rotation shaft 65 of the first light guide pin 62 is not coaxial with the rotation shaft 64 of the pointer 6 as shown in FIG. Specifically, the distal end portion 621 is configured to be rotatable inside the first reflecting portion 41. That is, the rotation locus of the tip portion 621 of the first light guide pin 62 indicated by a one-dot difference line of 65A is configured to be inside the first reflection portion 41. For this reason, even in a configuration in which the rotating shaft 65 is not coaxial with the rotating shaft 64, it becomes possible to guide the emitted light from the tip portion 621 to the first reflecting portion 41 according to the optical paths P71, P72, and P73. By rotating the pin 62, the first auxiliary indicators 33B, 33C, and 33D can be rotated and viewed. Therefore, also in this embodiment, the above-described effect can be obtained.

  In the above example, the scale part 31, the first reflection part 41, and the second reflection part 51 are provided in an arc shape, but the present invention is not limited to this. These can also be provided, for example, in an elliptical arc shape.

  In addition, it is not restricted to the example mentioned above, These combinations and other various modifications can be considered.
