Description

  The present invention relates to an instrument in which an indicator unit indicates an indicator unit.

  Conventionally, a pointer instrument for displaying a vehicle speed or the like is a character in which a pointer that is rotated by a rotating motion of a rotating inner unit and an indicator portion for displaying the vehicle speed or the like are formed in an arc shape along a rotation locus of the pointer. A vehicle speed is displayed by the pointer indicating the indicator portion.

Further, a power meter that displays the output of the engine is disclosed as a pointer instrument (see Patent Document 1). This is to calculate and display the engine output based on the torque of the shaft that transmits the engine output to the tire. In the embodiment, the dial is divided into a positive area and a negative area. It is described that one indicator indicates the indicator portion formed in the above and displays the output of the engine. A region where the torque is positive is a power region representing a running state output from the engine, and a region where the torque is negative is a charge region representing a running state where regenerative power generation is performed during deceleration. The indicator portion in the power region and the indicator portion in the charge region are formed on the same arc along the turning locus of the pointer that is turned by the rotational movement of the turning inner unit.
JP 2005-37163 A

  However, in the above-described power meter, the indicator that is formed on the same arc along the turning trajectory of the pointer indicates the indicator that rotates, for example, the indicator indicates the indicator of the charge region. In this case, it is difficult to intuitively distinguish the charge area of the indicator portion indicated by the pointer from the power area. This problem becomes more prominent when the index portion is divided into three or more areas and these plural areas are formed on the same arc along the turning locus of the rotating pointer.

  This problem is not limited to the indicator portion formed by dividing into a plurality of areas, and a plurality of indicator portions for displaying a plurality of pieces of information are arranged on the same arc along the turning locus of the rotating pointer. This is a problem common to instruments that form and indicate these with a rotating pointer.

  This problem is a problem common to instruments that indicate and display these indicator parts with two or more hands having the same rotation center.

  These problems are because the movement of the pointer draws a turning trajectory due to the rotational movement of the turning inner unit, and therefore it is necessary to form an indicator portion indicated by the pointer on the arc along the turning trajectory of the pointer. It is a problem that arises. Therefore, if the rotational motion of the rotating inner unit can be converted into a polygonal motion combining a linear motion and a motion that changes the moving direction, the polygonal motion is used as an instruction unit that instructs the index unit. It becomes possible. Thereby, an indicator part can be formed along the trajectory of the polygonal movement of the instruction part, and the indicator parts along each side of the polygon can be easily intuitively identified from each other.

  The present invention has been made in view of such circumstances, and provides an instrument in which an instruction unit that moves by converting the rotational motion of a rotating inner unit into a polygonal motion indicates an index unit. Objective.

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

  The meter according to claim 1, wherein the indicator portion is formed along each side of the regular polygon and has a light-transmitting display plate and is arranged behind the display plate and rotates around the center of the regular polygon. A rotating inner unit having a shaft, a sun gear disposed between the display plate and the rotating inner unit, fixed to the rotating shaft, and disposed on the outer peripheral side of the sun gear at a position concentric with the sun gear, on the inner peripheral side A ring gear having internal teeth on the inner surface of the ring gear, and one indicating portion for indicating the indicator portion from the rear side of the display plate is formed at a position facing the display plate while meshing with both the internal gear of the ring gear and the sun gear. A planetary gear, a display board, a rotating inner unit, and an instrument housing to which the ring gear is fixed, and the indicator moves along the side into a regular polygon shape by rotation of the rotating shaft, and the indicator is an indicator To indicate the position of the indicator in the planetary gear, the number of teeth of the sun gear, Wherein the inner teeth of the ring gear, that have set the number of teeth of the planetary gear.

  In this configuration, the rotational motion of the rotating internal unit is converted into a regular polygonal movement of the pointing portion formed on the planetary gear by combining the sun gear, the ring gear, and the planetary gear, and has a light-transmitting display. The indicator unit indicates the indicator part formed along each side of the regular polygon on the plate from the back side of the display board. As a result, converting the rotational motion of the rotating inner unit into a polygonal movement is realized by converting it into a regular polygonal movement, and the indicator unit that moves to the regular polygonal shape indicates the indicator unit. Can be provided.

  The meter according to claim 2 is characterized in that the indicator portions formed along each side are indicator portions for displaying different information.

  In this configuration, since the index portions for displaying different information are formed along each side of the regular polygon, these index portions are arranged in the same arc along the turning locus of the pointer. Compared with the case where it is, it can make it easy to identify mutually intuitively.

  The meter according to claim 3 is characterized in that the indicator portions formed along each side are indicator portions for displaying different areas in one piece of information.

  In this configuration, since the indicator portions for displaying different areas in one piece of information are formed along each side of the regular polygon, the indicator portions of these regions are arranged along the turning locus of the pointer. Compared to the case where they are arranged in the same arc shape, it is possible to easily identify each other intuitively.

  The meter according to claim 4 is provided with two or more planetary gears. Thereby, since two or more instruction units indicate the index unit, two or more information contents can be displayed at the same time while obtaining the above-described effect.

  The meter according to claim 5 is characterized in that each of the indicator portions has a straight scale line along each side of the regular polygon. Thereby, since the indicator moves along the graduation line, it can be more easily recognized which of the indicator portions formed along each side is indicated by the indicator.

  The meter according to claim 6 is characterized in that the indicating unit includes a light emitting unit. Thereby, since it becomes easier to identify the movement of the instruction unit, it is possible to more easily recognize which of the index units is instructed by the instruction unit.

  Hereinafter, the instrument by this invention is demonstrated based on drawing.

(First embodiment)
A hybrid vehicle 100 on which an instrument according to the first embodiment of the present invention is mounted includes the main system configuration shown in FIG.

  When the hybrid vehicle 100 starts, the electric motor 101 is operated by electric power from the high voltage battery 102. The electric force from the electric motor 101 is transmitted to the driving wheel 107 via the transmission 106 to drive the driving wheel 107. The inverter 105 converts the DC power from the high-voltage battery 102 into AC power, drives the motor 101, and operates the motor 101.

  During acceleration, both the engine 103 and the electric motor 101 are operated, and the driving wheel 107 is driven by both the electric power from the electric motor 101 and the engine power from the engine 103. Engine power from the engine 103 is transmitted to the drive wheels 107 via the power split mechanism 104 and the transmission 106 to drive the drive wheels 107. During constant travel, the engine 103 drives the drive wheels 107 via the power split mechanism 104 and the transmission 106.

  At the time of deceleration, charging is performed by regenerative power generation by the electric motor 101. Regenerative power generation is power generation in which the kinetic energy of the hybrid vehicle 100 is converted into electric energy by the electric motor 101 at the time of braking, and the high voltage battery 102 is charged with the converted electric energy as electric power. As described above, in the hybrid vehicle 100, the electric motor 101 is skillfully used under the driving conditions that the engine 103 is not good at and the engine 103 is operated efficiently when the engine 103 is operated.

  These controls are performed by a hybrid control unit (Hybrid ECU) 108 (FIG. 6) constituted by a microcomputer or the like.

  In FIG. 2, the ecometer 1 that is a meter according to the first embodiment of the present invention is disposed in front of the driver's seat of the hybrid vehicle 100, and the instruction unit 51 instructs the indicator unit 21-23 to indicate information as a hybrid vehicle. The running efficiency of 100 is displayed.

  The indicator unit 21-23 determines the driving efficiency of the hybrid vehicle 100, the indicator unit 21 in the economy / ecology (eco, ECO) region where the driving efficiency is high, the indicator unit 22 in the power (POWER) region where the driving efficiency is low, and the regeneration. It is formed on the display panel 2 separately from the indicator portion 23 in a charge (CHARGE) region where charging is performed by power generation. The indicator portion 21-23 is formed of a fluorescent material that emits light by ultraviolet rays from an ultraviolet (UV) light 7 (FIG. 3), which will be described later, and is printed on the back surface of the display board 2 formed of a light-transmitting acrylic resin or the like. And so on.

  Each of the indicator portions 21-23 includes scale lines 211-231 and characters 212-232, and is formed on the display board 2 along each side of a regular triangle that is a regular polygon. The scale lines 211-231 are each formed as a straight line along each side of the regular triangle, and in FIG. 2, each is formed as each side of the regular triangle.

  Although the numerical values and units are not described in the indicator portion 21-23 shown in FIG. 2, the units of the indicator portions 21 and 22 are, for example, the travel distance (km / km, km) and the fuel consumption (liter, L ) Based on the instantaneous fuel consumption (km / L). The power region can be set to 0 to 10 (km / L) from the charge region side to the eco region side, and the eco region can be set to 10 to 30 (km / L) from the power region side to the charge region side. The power region refers to a region where the vehicle travels with high power output, and when the vehicle travels with maximum traveling efficiency in the eco region, it leads to the charge region.

  As shown in FIG. 3, the movement 6 that is a rotating inner unit is disposed behind the display panel 2, and rotates around the center of the regular triangle, that is, the center of the regular triangle formed by the scale lines 211-231. A shaft 61 is provided. The movement 6 is composed of, for example, a cross coil actuator or a stepping motor, and rotates the shaft 61 by an angle corresponding to an electric signal from the outside, and is mounted on the printed circuit board 8.

  The sun gear 3 having 30 teeth is disposed between the display plate 2 and the movement 6 and is fixed to the rotary shaft 61. The ring gear 4 is disposed concentrically with the sun gear 3 on the outer peripheral side of the sun gear 3, and has inner teeth 41 with 90 inner teeth on the inner peripheral side of the ring gear 4. The planetary gear 5 with 30 teeth meshes with both the internal teeth 41 of the ring gear 4 and the sun gear 3, and the one indicator 51 described above passes through the light-transmitting display plate 2 and behind the display plate 2. The planetary gear 5 is formed at a position facing the display plate 2 so as to indicate the indicator portion 21-23 from the side.

  The instruction unit 51 includes a light emitting unit, and specifically, a fluorescent material that emits light by ultraviolet rays from the UV light 7 is applied to the surface of the instruction unit 51. The UV light 7 is disposed at a position where the indicator part 21-23 and the instruction part 51 can be irradiated with ultraviolet rays, and is electrically connected to the printed circuit board 8. In order to prevent the ultraviolet light from the UV light 7 from directly entering the eyes of the viewer, a light-transmitting cover 9 formed of a smoke-like (frosted glass-like) acrylic resin is provided between the UV light 7 and the display panel 2. Place on the viewing side.

  The display board 2, the ring gear 4, the UV light 7, the printed circuit board 8 on which the movement 6 is mounted, and the light transmissive cover 9 are fixed to a case 11 that is an instrument housing. Therefore, it can be said that the display plate 2, the ring gear 4, and the movement 6 are fixed to an instrument housing including the case 11.

  In FIG. 4, when the sun gear 3 is rotated in the direction of the arrow R1 around the rotation shaft 61 by the rotation of the rotation shaft 61, the planetary gear 5 is rotated in the direction of the arrow R2, and the indicating unit 51 The indicator portion 21-23 is indicated by moving along the side of the square shape, that is, on the line L1 in the direction of the arrow M1. On the other hand, when the sun gear 3 is rotated around the rotation shaft 61 in the direction opposite to the arrow R1, the planetary gear 5 is rotated in the direction opposite to the arrow R2, and the indicating unit 51 is in the shape of the regular triangle described above. Along the line L1, that is, in the direction opposite to the arrow M1, moves to indicate the indicator portion 21-23.

  In order to rotate the sun gear 3 around the rotation shaft 61 by the rotation of the rotation shaft 61 and move the instruction unit 51 along the side in the regular triangle shape, the position of the instruction unit 51 in the planetary gear 5 is determined. It is necessary to appropriately set the number of teeth of the sun gear 3, the number of internal teeth of the ring gear 4, and the number of teeth of the planetary gear 5. Specifically, as described above, the number of teeth of the sun gear 3 and the planetary gear 5 is set to 30 for example, and the number of internal teeth of the ring gear 4 is set to 90, which is three times the number of teeth of the planetary gear 5. The position of the instruction unit 51 in the planetary gear 5 is set as shown in FIG.

  FIG. 5 schematically shows the relationship between the position of the instruction unit 51 of the planetary gear 5 and the movement of the instruction unit 51 due to the rotation of the rotary shaft 61. Since the indicator 53 arranged at the center of the planetary gear 5 rotates on the line L3 by the rotation of the rotary shaft 61, the movement is converted into a triangular movement combining a linear movement and a movement that changes the moving direction. The rotational motion of 6 cannot be converted. In the planetary gear 5, the indication unit 52 disposed between the indication units 51 and 53 moves on the line L <b> 2 by the rotation of the rotary shaft 61. It is not sufficient in terms of conversion to a square-shaped movement.

  On the other hand, since the instruction unit 51 moves on the line L1 by the rotation of the rotary shaft 61, the movement of the movement 6 is changed into a regular triangular movement that combines a linear movement and a movement that changes the moving direction. Can convert and move. Although not shown in the drawing, the indicator arranged outside the indicator 51 in the radial direction of the planetary gear 5 moves in a shape deviating from the regular triangle shape from the line L1, and thus moves in a regular triangle shape. It is insufficient in terms of conversion. However, the extent to which the instruction unit arranged in the vicinity of the instruction unit 51 can be allowed to be converted into a regular triangular movement is a problem in product specifications, and is not limited to the position of the instruction unit 51. .

  The turning on / off control of the UV light 7 and the rotation control of the movement 6 are performed by a meter control device (meter ECU) 12 composed of a microcomputer or the like in FIG. A hybrid control unit (Hybrid ECU) 108 can control the electric motor 101, the engine 103, and the like, and can input a travel efficiency signal of the hybrid vehicle 100 to the meter control unit 12. Configured. The travel efficiency signal includes information indicating which of the eco-region, the power region, and the charge region is the travel efficiency.

  The meter control device 12 controls the rotation of the movement 6 so that the instruction unit 51 instructs the indicator unit 21-23 based on the traveling efficiency signal from the hybrid control device 108.

  The operation of the ecometer 1 of the present embodiment in the above configuration will be described.

  When an ignition switch (not shown) is turned on, the meter control device 12 detects it and starts operation. The meter control device 12 turns on the UV light 7 in FIG. Based on the traveling efficiency signal, the rotation of the movement 6 is controlled. The ultraviolet rays of the lit UV light 7 cause the indicator portion 21-23 and the instruction portion 51 to emit light and display in FIG. Accordingly, the instruction unit 51 for performing light emission display instructs the indicator unit 21-23 for performing light emission display from the back side of the display plate 2 through the light-transmitting display plate 2.

  Hereinafter, the rotation control of the movement 6 and the movement of the instruction unit 51 that instructs the indicator unit 21-23 will be described.

  For example, a case is assumed in which the rotation of the movement 6 is controlled based on a traveling efficiency signal, and the instruction unit 51 instructs the indicator unit 21 in the eco region as shown in FIG. When the traveling efficiency increases with respect to the state shown in FIG. 4, the movement 6 is controlled so that the sun gear 3 rotates in the direction opposite to the arrow R <b> 1 in FIG. 4. Thereby, the planetary gear 5 rotates in the direction opposite to the arrow R2, and the instruction unit 51 moves linearly along the scale line 211 in the direction opposite to the arrow M1. That is, the rotational movement of the movement 6 is converted into a linear movement of the instruction unit 51. Further, when the traveling efficiency increases and reaches the charge region, the instruction unit 51 moves on the line L1 from the scale line 211 direction to the scale line 231 direction. That is, the rotational movement of the movement 6 is converted into the movement of the instruction unit 51 that changes the direction from the scale line 211 direction to the scale line 231 direction on the line L1.

  On the other hand, when the traveling efficiency is lowered with respect to the state shown in FIG. 4, the rotation of the movement 6 is controlled so that the sun gear 3 rotates in the direction of the arrow R1. Thereby, the planetary gear 5 rotates in the arrow R2 direction, and the instruction unit 51 moves linearly along the scale line 211 in the arrow M1 direction. That is, the rotational movement of the movement 6 is converted into a linear movement of the instruction unit 51. Further, when the traveling efficiency decreases and reaches the power region, the instruction unit 51 moves on the line L1 from the scale line 211 direction to the scale line 221 direction. That is, the rotational movement of the movement 6 is converted into the movement of the instruction unit 51 that changes the direction from the scale line 211 direction to the scale line 221 direction on the line L1.

  Accordingly, the instruction unit 51 moves on the line L1 by the rotation of the movement 6 (rotating shaft 61). Therefore, the rotation movement of the movement 6 is a regular triangular movement that combines a linear movement and a movement that changes the moving direction. Can be converted and moved.

  In this way, the rotational movement of the movement 6 is converted into a regular triangular movement of the indicating portion 51 formed on the planetary gear 5 by combining the sun gear 3, the ring gear 4, and the planetary gear 5 to transmit light. The indicator unit 51 instructs the indicator part 21-23 formed along each side of the regular triangle on the display panel 2 having the property, and the indicator part 21-23 from the rear side of the display board 2. Thereby, converting the rotational motion of the movement 6 into a triangular movement is realized by converting the movement into a regular triangular movement, and the instruction unit 51 moving to the regular triangular shape is used as the indicator unit 21-23. Can be realized.

  Therefore, the indicator portion 21-23 can be formed along the regular triangular movement trajectory of the indicating portion 51, and the indicator portion 21-23 along each side of the regular triangle can be formed along the turning locus of the pointer. Compared to the case where they are arranged in the same arc shape, it is possible to easily identify each other intuitively. In addition, since the indicator portion 21-23 is formed along each side of the same regular triangle, the indicator portion 21-23 has a relationship between the eco region, the power region, and the charge region that are respectively represented. It can be displayed as you feel.

  In addition, each of the indicator portions 21-23 includes scale lines 211-231, and the indicator 51 moves along the scale lines 211-231. Therefore, any of the indicator portions 21-23 formed along each side It can be more easily recognized whether the instruction unit 51 has instructed.

  In addition, since the indicator portion 21-23 and the indicator portion 51 emit and display light by the ultraviolet light of the UV light 7, the indicator portion 21-23 is easily visible and the movement of the indicator portion 51 is more easily identified. It can be more easily recognized which of the units 21-23 is instructed by the instruction unit 51.

  The ecometer 1 that is the meter according to the present embodiment described above includes a display board 2 having indicator portions 21-23 formed along each side of a regular triangle that is a regular polygon, and a light transmitting property. A movement 6 which is a rotating internal unit having a rotating shaft 61 at the center of a regular triangle and is arranged behind the plate 2, and a sun gear which is arranged between the display plate 2 and the movement 6 and fixed to the rotating shaft 61. 3 and a ring gear 4 that is disposed concentrically with the sun gear 3 on the outer peripheral side of the sun gear 3 and has inner teeth 41 on the inner peripheral side, and meshes with both the inner teeth 41 of the ring gear 4 and the sun gear 3. At the same time, the planetary gear 5 in which one indicating portion 51 for indicating the indicator portion 21-23 from the back side of the display plate 2 is formed at a position facing the display plate 2, the display plate 2, the movement 6, and the ring gear 4; A case that is a measuring instrument housing 1, and the rotation of the rotary shaft 61 causes the pointing unit 51 to move along the side in a regular triangle shape so that the pointing unit 51 points to the indicator unit 21-23. The position, the number of teeth of the sun gear 3, the number of internal teeth of the ring gear 4, and the number of teeth of the planetary gear 5 are set.

  Thereby, the indicator which moves by converting the rotational motion of the rotary inner unit into a polygonal motion can provide an instrument for indicating the indicator.

(Second Embodiment)
In the ecometer 1 of the first embodiment, the indicator portion 21-23 formed along each side of the regular triangle is moved to the regular triangle shape by the one indicating portion 51 formed on one planetary gear 5. I ordered, but it is not limited to this. In the power meter 10 which is an instrument according to the second embodiment of the present invention, in FIG. 7, the indicator portions 21 to 23 formed along each side of a regular square (square) are arranged on the two planetary gears 50 and 60. The formed instruction units 510 and 610 move to a regular quadrilateral shape and give instructions.

  When the instruction units 510 and 610 indicate the indicator units 24 and 25, respectively, the engine power from the engine 103 that is information and the electric power from the electric motor 101 that is information different from the engine power are displayed. The index unit 24 is an index unit for displaying engine power from the engine 103, and the index unit 25 is an index unit for displaying the electric power from the electric motor 101, and these have optical transparency. Printed on the display board 20. The indicator portions 24 and 25 are made of a fluorescent material that emits light by the ultraviolet rays from the UV light 7 described above.

  The indicator portions 24 and 25 include scale lines 241 and 251 and characters 242 and 252, respectively, and are formed on the display board 20 along each side of a regular quadrangle instead of a regular triangle. The scale lines 241 and 251 are each formed as two sides adjacent to each other in a regular square.

  Although the numerical values and units are not described in the index parts 24 and 25 shown in FIG. 7, the unit of the index part 24 is set to 100 percent (percent) of the engine power with respect to the total of the engine power and the electric power. The unit of 25 is defined as a 100-percentage (percentage) of electric power with respect to the sum of engine power and electric power. In addition, both the indicator portions 24 and 25 are set to 0 to 100 (percent) from the lower side to the upper side in FIG.

  The sun gear 30 having 40 teeth is fixed to the rotary shaft 61 instead of the sun gear 3, and the ring gear 40 having the internal teeth 410 having 80 internal teeth is the outer periphery of the sun gear 30 instead of the ring gear 4. The sun gear 30 and the sun gear 30 are arranged on the side. Further, the planetary gears 50 and 60 having 20 teeth mesh with both the inner teeth 410 of the ring gear 40 and the sun gear 30 instead of the planetary gear 5, and the indication unit 510 passes through the light-transmitting display plate 20. The planetary gear 50 is formed at a position facing the display plate 20 so as to indicate the indicator portion 24 from the back side of the display plate 20. The instruction unit 610 is formed at a position facing the display plate 20 in the planetary gear 60 so that the indicator unit 25 is indicated from the rear side of the display plate 20 through the light-transmitting display plate 20.

  Regardless of the rotational position of the sun gear 30, the rotation shaft 61 and the centers of the instruction units 510 and 610 are arranged on a straight line. As a result, the sum of the 100-percentage of the index unit 24 instructed by the instruction unit 510 and the 100-percentage of the index unit 25 instructed by the instruction unit 610 is constantly set to 100%. The instruction units 510 and 610 include a light emitting unit, and specifically, a fluorescent material that emits light by ultraviolet rays from the UV light 7 is applied to the surfaces of the instruction units 510 and 610. The display board 20 and the ring gear 40 are fixed to the case 11 which is an instrument housing.

  When the sun gear 30 is rotated in the direction of the arrow R10 around the rotation shaft 61 by the rotation of the rotation shaft 61, the planetary gear 50 is rotated in the direction of the arrow R20, and the instruction unit 510 has the above-described regular square shape. Along the line L10, that is, in the direction of the arrow M10, indicates the indicator unit 24. At this time, the planetary gear 60 rotates in the direction of the arrow R30, and the instruction unit 610 indicates the indicator unit 25 by moving along the side in the above-described regular square shape, that is, on the line L10 in the direction of the arrow M20. To do.

  On the other hand, when the sun gear 30 is rotated around the rotation shaft 61 in the direction opposite to the arrow R10, the planetary gear 50 is rotated in the direction opposite to the arrow R20, and the indicating unit 510 is formed into a side of the regular square shape described above. Along the line L10, that is, in the direction opposite to the arrow M10, indicates the indicator section 24. At this time, the planetary gear 60 rotates in the direction opposite to the arrow R30, and the indicating unit 610 moves along the side in the above-described regular square shape, that is, on the line L10 in the direction opposite to the arrow M20. The unit 25 is instructed.

  In order to rotate the sun gear 30 around the rotation shaft 61 by the rotation of the rotation shaft 61 and move the indication units 510 and 610 along the sides in the above-described regular square shape, the indication unit 510 in the planetary gear 50 is used. , The position of the indicator 610 in the planetary gear 60, the number of teeth of the sun gear 30, the number of internal teeth of the ring gear 40, and the number of teeth of the planetary gears 50 and 60 need to be set appropriately. Specifically, as described above, the number of teeth of the sun gear 30 is, for example, 40, the number of teeth of the planetary gears 50, 60 is, for example, 20, and the number of internal teeth of the ring gear 40 is the number of teeth of the planetary gears 50, 60. 8 is set to 80, and the position of the indicating unit 510 in the planetary gear 50 and the position of the indicating unit 610 in the planetary gear 60 are set as shown in FIG.

  FIG. 8 schematically shows the relationship between the position of the instruction unit 510 in the planetary gear 50, the position of the instruction unit 610 in the planetary gear 60, and the movement of the instruction units 510 and 610 due to the rotation of the rotary shaft 61. Since the indicator 530 arranged at the center of the planetary gear 50 and the indicator 630 arranged at the center of the planetary gear 60 rotate on the line L30 by the rotation of the rotary shaft 61, the indicator 530 moves with a linear motion. The rotational movement of the movement 6 cannot be converted into a quadrangular movement combined with a movement for changing the direction. In addition, the indication unit 520 arranged outside the instruction unit 510 in the radial direction of the planetary gear 50 and the instruction unit 620 arranged outside the instruction unit 610 in the radial direction of the planetary gear 60 are rotated by the rotation shaft 61. Therefore, the movement on the line L20 is not sufficient in deviating from the movement of the quadrangular shape and converting to the movement of the regular quadrangular shape.

  On the other hand, since the instruction units 510 and 610 move on the line L10 by the rotation of the rotation shaft 61, the rotation of the movement 6 is converted into a regular quadrangular movement that combines a linear movement and a movement that changes the moving direction. You can change the movement and move. However, the extent to which the instruction unit arranged in the vicinity of the instruction units 510 and 610 can be tolerated in terms of converting the movement into a regular square shape is a problem in product specifications. It is not limited to position.

  The meter control device 12 controls the rotation of the movement 6 so that the instruction units 510 and 610 indicate the indicator units 24 and 25 based on the engine power signal and the electric power signal from the hybrid control device 108. .

  In the power meter 10 of the present embodiment configured as described above, the rotation control of the movement 6 and the movement of the instruction units 510 and 610 for instructing the indicator units 24 and 25 will be described.

  For example, it is assumed that the rotation of the movement 6 is controlled based on the engine power signal and the electric power signal, and the instruction units 510 and 610 indicate the indicator units 24 and 25 as shown in FIG. When the engine power increases and the electric power decreases with respect to the state shown in FIG. 7, the movement 6 is controlled so that the sun gear 30 rotates in the direction opposite to the arrow R10 in FIG. As a result, the planetary gear 50 rotates in the direction opposite to the arrow R20, and the instruction unit 510 moves linearly along the scale line 241 in the direction opposite to the arrow M10. At this time, the planetary gear 60 rotates in the direction opposite to the arrow R30, and the instruction unit 610 moves linearly along the scale line 251 in the direction opposite to the arrow M30. That is, the rotational movement of the movement 6 is converted into a linear movement of the instruction units 510 and 610.

  On the other hand, when the engine power decreases and the electric power increases with respect to the state shown in FIG. 7, the movement 6 is controlled so that the sun gear 30 rotates in the direction of arrow R <b> 10 in FIG. 7. Thereby, the planetary gear 50 rotates in the direction of the arrow R20, and the instruction unit 510 moves linearly along the scale line 241 in the direction of the arrow M10. At this time, the planetary gear 60 rotates in the direction of the arrow R30, and the instruction unit 610 moves linearly along the scale line 251 in the direction of the arrow M30. That is, the rotational movement of the movement 6 is converted into a linear movement of the instruction units 510 and 610. Further, when the engine power decreases and the electric power increases, the instruction unit 510 moves on the line L10 by changing the direction of movement along the scale line 241 by 90 degrees. At this time, the instruction unit 610 moves 90 degrees along the scale line 251 on the line L10. That is, the rotational movement of the movement 6 is converted into the movement of the instruction units 510 and 610 that change the moving direction on the line L10.

  In addition, the instruction units 510 and 610 are connected to each other so that the sum of the 100 percent at which the instruction unit 510 displays the indicator unit 24 and the 100 percent at which the instruction unit 610 displays the indicator unit 25 is 100%. Move on L10.

  Therefore, since the instruction units 510 and 610 move on the line L10 by the rotation of the movement 6 (the rotating shaft 61), the movement of the movement 6 is converted into a regular quadrangular movement that combines a linear movement and a movement that changes the moving direction. It can move by converting rotational motion.

  As described above, the rotational movement of the movement 6 is performed by combining the sun gear 30, the ring gear 40, and the planetary gears 50, 60, and the regular square movements of the indication units 510, 610 formed on the planetary gears 50, 60. The indicator portions 24 and 25 formed along each side of the regular quadrilateral on the display board 20 having light transmittance, and the indicator portions 24 and 25 from the rear side of the display board 20 are indicated by the indication portions 510 and 610. Directs. Thus, the rotational movement of the movement 6 is converted into a quadrangular movement by converting it into a regular quadrangular movement, and the instruction units 510 and 610 that move to the regular quadrangular shape are used as the indicator unit 24. , 25 can be realized.

  Accordingly, the indicator portions 24 and 25 can be formed along the locus of movement of the regular quadrangular shape of the instruction portions 510 and 610, and the indicator portions 24 and 25 along the sides of the regular tetragon are used as the turning locus of the pointer. Compared with the case where they are arranged along the same arc shape, it is possible to easily identify each other intuitively. In addition, since the indicator portions 24 and 25 are formed along the same square sides, the indicator portions 24 and 25 respectively display the engine power and the electric power that are represented so that they can be related to each other. it can.

  Moreover, since the indicator parts 24 and 25 are each provided with the scale lines 241 and 251 and the indicator parts 510 and 610 move along the scale lines 241 and 251, respectively, the index parts 24 formed along each side. , 25 can be recognized more easily by the instruction units 510, 610.

  Further, since the two instruction units 510 and 610 indicate the indicator units 24 and 25, two pieces of information on the engine power and the electric power can be displayed simultaneously.

  Moreover, since the sum of the 100 percent of the index unit 24 instructed by the instruction unit 510 and the 100 percent of the index unit 25 instructed by the instruction unit 610 is displayed as 100%, the contribution of the motor 101 And the contribution ratio of the engine 103 can be easily recognized intuitively.
