Description

  The present invention relates to an instrument device for a vehicle, and more particularly to an instrument device including a display unit that switches and displays a plurality of vehicle information and a pointer that indicates a scale portion displayed on the display unit.

  Conventionally, various proposals have been made for instrument devices (so-called meters) mounted on vehicles such as automobiles. For example, the pointer is provided on the dial so as to be rotatable, and the display shape formed on the dial is obtained by irradiating the back of the dial with light from a light source such as an LED (Light Emitting Diode). An analog type instrument device that displays light emission is known. With this analog type instrument device, it is difficult to change the display format of the dial.

  Therefore, as disclosed in Patent Document 1, a first display mode for displaying a first image such as a scale of an analog type meter and a second image different from the first image are displayed on the image display device. There is known a graphic-type instrument device capable of switching the display mode by displaying the second display mode. In this graphic type instrument device, the image of the image display device can be changed, and the design (so-called design) as interior of the vehicle interior is improved.

  Further, in the first display mode, the scale of the first image is indicated by a pointer, and in the second display mode, the pointer is retracted to a retract position set outside the display area of the second image, and the pointer is placed behind the frame. By hiding, the appearance of the display in the second display mode is greatly improved.

A contour is formed by a black or other light-shielding ink layer 33 screen-printed on the screen. As shown in FIG. 3, the water temperature scale 3b and the fuel scale 3c are formed by a translucent ink layer 34 such as white, and are visually recognized in white. The various indicators 3d are formed of a light-transmitting ink layer (not shown) of smoke color or the like. The liquid crystal see-through part 3 a does not have a predetermined ink layer, and is formed by the transparency of the base material 31 through the printing opening 32.

  The pointer 2 includes a light-shielding cover portion 22 made of a light-shielding synthetic resin such as black ABS (acrylonitrile butadiene styrene) resin, and an indication portion 21 made of a transparent PC resin, and a part of the indication portion 21 is a drive shaft.

In the light shielding cover portion 22, the light from the pointer light source 43 is received by the light receiving portion 23, reflected by the upper reflecting surface 24 to the indicating portion 21, and red hot provided on the lower surface of the indicating portion 21. The reflective layer 25 made of stamp foil emits light.

  The pointer 2 includes an octopus pointer 2T for rotating the front surface of the liquid crystal see-through unit 3a, a water temperature pointer 2W for rotating the front surface of the water temperature scale 3b, and a fuel pointer for rotating the front surface of the fuel scale 3c. It consists of 3 pieces, 2F. The dial 3 has a through hole 35 at a position corresponding to the drive shaft 42, and the drive shaft 42 and the pointer 2 can be connected through the through hole 35.

  The case body 5 is made of an impermeable synthetic resin such as white PP (polypropylene) resin, and has a surrounding wall 51 so as to surround the drive shaft 42 and the pointer light source 43. The enclosure wall 51 prevents the light emitted from the pointer light source 43 from leaking to the liquid crystal display module 1, the water temperature scale 3b, and the fuel scale 3c, and the light emitted from the dial light source 44 to the water temperature indicator 2W and the fuel indicator 2F. Prevent leakage. Further, the surrounding wall 51 prevents light emitted from the liquid crystal display module 1 from leaking to the pointer 2.

Further, the facing plate 6 includes a hook-shaped hood portion 62 that covers an upper portion of the octopus pointer 2T so that the light-shielding cover portion 22 of the octopus pointer 2T cannot be visually recognized by the driver. The inner surface 61a of the upright wall 61 is provided with a texture to prevent reflection of illumination from the liquid crystal display module 1.

  The liquid crystal display module 1 has a normal display mode N (FIG. 1), a sports display mode S (FIG. 6), and an enlarged display mode K (FIG. 7). As shown in FIG. 4, an ENGIN START STOP button 71 for starting and stopping the engine, and a SPORT button for switching between a normal display mode N and a sports display mode S are provided at the left and right positions of the handle 8 of the instrument panel 9 of the vehicle. 72 is mounted.

  As shown in FIG. 5, when the ACC (accessory position) is turned “ON” by the ENGIN START STOP button 71 in step F1, the display switching control unit displays the normal display mode N in step F2. In step F3, it is determined whether or not the shift position of the vehicle is “D (drive)”. If NO, the normal display mode N is continued in step F4. If YES, the SPORT button 72 is “ It is determined whether or not “ON”. If step F5 is No, the normal display mode N is continued in step F6, and if Yes, the display is switched to the sports display mode S in step F7. In this way, the display switching control unit can switch to the sports display mode S only when the shift position is “D”. Even if the driver does not turn off the SPORT button 72 in step F5, if the driver changes the vehicle shift position to other than “D” in step F3, the normal display mode N is automatically set in step F4. Switch.

  The normal display mode N is a display mode that is normally displayed. As shown in FIG. 1, a speedometer image 1a, which is a digital speedometer 100, is displayed at the upper center, a shift position image 1b is displayed on the left side of the speedometer image 1a, and a circle is displayed below the speedometer image 1a. An octopus scale image 1c in which a plurality of scales are arranged in an arc shape, and an octopus number image 1q corresponding to each scale are displayed on the inner side (pointer 2T side) of the octopus scale image 1c. The inner diameter R1 of each scale of the octopus scale image 1c is set smaller than the outer diameter R3 of the octopus pointer 2T. Here, the inner diameter R1 indicates the distance from the rotation center axis X of the octopus pointer 2T to the position closest to the rotation center axis X of each scale of the octopus scale image 1c. Further, the outer diameter R3 indicates the distance from the rotation center axis X of the octopus pointer 2T to the pointing portion tip 26 of the octopus pointer 2T.

  By forming in this way, the instruction unit 21 can instruct the octopus scale image 1c. The analog tachometer 200 is constructed by reading the instruction unit 21 and the tachometer scale image 1c.

  In the sports display mode S, the driver operates the SPORT button 72 when the driver emphasizes acceleration-oriented driving, powerful driving on an uphill road, or when applying a light engine brake on a downhill. Is the mode displayed.

  In the sport display mode S, as shown in FIG. 6, a reduced speedometer image 1d obtained by reducing the speedometer image 1a is displayed at the upper right end. The sport display mode S is a second shift position image having a gear number image 1e displayed at the same position as the shift position image 1b and a shift UP / DOWN image 1f displayed on the right side of the gear number image 1e. 1g is displayed.

  The sports display mode S corresponds to each scale on the outer side (opposite side of the pointer 2T) of the large-diameter octopus scale image 1h in which a plurality of scales are arranged in an arc shape in the center, and on the outside of the octopus scale image 1c. The same octopus numeral image 1q as 1c is displayed. The large-diameter octopus scale image 1h includes an angle P3 from the zero (zero) scale to the horizontal of the large-diameter octopus scale image 1h and an angle P4 between the scales, and an angle P1 from the 0 scale to the horizontal of the octopus scale image 1c and each scale. It is set to the same angle as the interval angle P2. Further, the inner diameter R2 of each scale of the large diameter octopus scale image 1h is set larger than the inner diameter R1. The inner diameter R2 is set larger than the outer diameter R3. Here, the inner diameter R2 indicates the distance from the rotation center axis X of the octopus pointer 2T to the position closest to the rotation center axis X of each scale of the large diameter octopus scale image 1h.

  In the sports display mode S, the instruction unit image 2a that operates in conjunction with the operation of the octopus pointer 2T is displayed on the extension line of the instruction unit 21 on the liquid crystal display module 1. The inner diameter of the instruction part image 2a is set to be the same as the outer diameter R3. Further, the outer diameter R4 of the instruction part image 2a is set larger than the inner diameter R2. Here, the outer diameter R4 indicates the distance from the rotation center axis X of the octopus pointer 2T to the tip of the pointing part image 2a.

  Since the outer diameter R3 is smaller than the inner diameter R2, it is impossible for the indicator 21 to indicate the large-diameter octopus scale image 1h, but by forming in this way, the outer diameter R4 is larger than the inner diameter R2. Therefore, it is possible to indicate the large-diameter octopus scale image 1h with the instruction part image 2a. A large-diameter analog type tachometer 200 is constructed by interpreting the indication portion image 2a and the large-diameter tachometer scale image 1h. The instruction unit image 2a is displayed with substantially the same width as the instruction unit tip 26, and is displayed with the same red color as the light emission color of the instruction unit 21. Thereby, the sense of unity between the instruction unit 21 and the instruction unit image 2a can be produced.

  In addition, the octopus scale image 1c and the large-diameter octopus scale image 1h are switched by switching between the normal display mode N and the sport display mode S. However, as described above, the angular position of each scale is the same, and the radial position It becomes possible to change the size of the design of the tachometer 200 only by the change. By forming in this way, it is possible to reduce the driver's uncomfortable feeling due to the change in the angular position of the scale. In addition, since it is not necessary to change the setting value (point specification) of the finger 2T for indicating the scale, it is possible to reduce the design man-hours.

  Further, even if the octopus scale image 1c and the large-diameter octopus scale image 1h are switched, the position of the octopus numeral image 1q is not changed as described above, and the tachometer 200 is obtained by switching each scale between the outside and inside of the octopus numeral image 1q. The size of the design can be changed. By being formed in this way, it is possible to reduce the driver's uncomfortable feeling due to the change of the numerical position. Moreover, a novel design effect can be produced.

  In addition, although the tachometer 200 is an analog type having a large diameter, the instruction unit 21 is the instruction unit image 2a. Therefore, the instruction unit 21 of the actual octopus pointer 2T can be shortened, and the balance adjustment of the octopus pointer 2T can be performed. Therefore, it is not necessary to increase the size of the light-shielding cover portion 22, and the design of the light-shielding cover portion 22 can be improved. In addition, since the size of the pointer driving unit 41 that drives the octopus pointer 2T can be reduced, the cost can be reduced.

  As illustrated in FIG. 2, the instruction unit 21 has an inclined top surface 27 that approaches the liquid crystal display module 1 as the top surface moves toward the instruction unit tip 26. By forming in this way, the relationship between the instruction unit 21 and the instruction unit image 2a is emphasized, and the sense of unity between the instruction unit 21 and the instruction unit image 2a can be improved.

  Further, as shown in FIG. 8A to FIG. 8D, the liquid crystal display module 1 starts from the non-display state of the instruction portion image 2a in FIG. Before reaching the display state, the expandable image 2b is displayed as shown in FIGS. The expandable image 2b is displayed until it gradually extends from the instruction portion tip 26 and reaches the length of the instruction portion image 2a. On the contrary, the expandable image 2b of FIGS. (C) and (d) is also displayed from FIG. (D) to FIG. (A). By being formed in this way, the indication part 21 of the octopus pointer 2T gradually changes and expands and contracts as compared with a simple switching between display and non-display of the indication part image 2a. Dynamic effects of the design can be produced.

  The enlarged display mode K is a mode in which when the vehicle detects an abnormality, the abnormality information is displayed to the driver and the entertainment information is displayed by the driver's operation. As shown in FIG. 7, the abnormality information is, for example, an enlarged image 1j such as a seat belt warning displayed when the driver starts the vehicle without wearing the seat belt.

  Further, as shown in FIG. 5, the display switching control unit determines whether or not there is an abnormality in the vehicle in Step F8. If No, the display mode before Step F8 is continued in Step F10. If Yes, the mode is switched to the enlarged display mode K in step F9. In step F11, it is determined whether or not the display time of the enlarged display mode K is “time-up”. If NO, the enlarged display mode K is continued in step F9. In F12, the display mode before step F8 is switched. In step F13, it is determined whether or not the ignition switch is turned off from ACC. If No, the process returns to step F3. If Yes, the program of the display switching control unit is terminated in step F14.

  In the enlarged display mode K, the reduced speedometer image 1d is displayed. If the normal display mode N is before switching, the shift position image 1b is displayed. If the switching display mode S is before switching, the second shift position image 1g is displayed. Is displayed. The octopus scale image 1c, the large-diameter octopus scale image 1h, the instruction part image 2a, and the octopus numeral image 1q are not displayed, and the seat belt warning or the like is enlarged at the position of the octopus scale image 1c or the large-diameter octopus scale image 1h. The image 1j is displayed. As described above, in the enlarged display mode K, the speedometer image 1a is set to the reduced speedometer image 1d, so that it is possible to perform enlarged display as much as possible while displaying information important for vehicle travel. Effective notification can be made.

  Incidentally, if the vehicle continues to detect an abnormality even after returning from the enlarged display mode K to the display mode (N, S) before the screen change, a warning is displayed in the liquid crystal display module 1 as shown in FIG. The lamp image 1m is displayed, or various indicators 3d related to the abnormality are lit on the dial 3. In this way, even if it is not the enlarged display mode K, the driver can be notified of the abnormality.

  As shown in FIG. 9, when the ignition switch is turned to ACC by the ENGIN START STOP button 71 in step L1, the pointer position control unit turns on the pointer light source 43 in step L2 and makes the instruction unit 21 indicate the position of the tacho scale image 1c. Move to. Thereafter, in step L3, it is determined whether or not the “enlarged display mode K” is selected. If No, the instruction position of the octopus scale image 1c is continued in step L4. If Yes, the instruction unit 21 is moved to the liquid crystal fluoroscopic part in step L5. The hood 62 is retracted to the retracted position set outside 3a, and the pointer light source 43 is turned off at the same time as the instruction unit 21 arrives at the retracted position.

  Next, in Step L6, it is determined whether or not the display time of the enlarged display mode K is “time up”, and if it is No, the retreat position is continued in Step L5, and if Yes, the step is performed. In L7, the octopus scale image 1c is moved to the designated position. In step L8, it is determined whether or not the ignition switch is turned off from ACC. If No, the process returns to step L3. If Yes, the instruction unit 21 is retracted to the hood 62 in step L9. In step L10, the program for the pointer position control unit is terminated.

  In this way, the octopus pointer 2T can be completely hidden behind the hood portion 62, so that the confusing visual recognition of the octopus pointer 2T can be eliminated and the appearance of the enlarged display mode K can be improved. Further, since the instruction unit 21 is the instruction unit image 2a, the instruction unit 21 of the octopus pointer 2T that is the substance can be shortened, and even if the analog type has a large diameter, the space of the hood unit 62 that hides the octopus pointer 2T can be saved. It can be made smaller and the design can be improved.

  A second embodiment of the present invention will be described. As shown in FIG. 10, the instruction part image 2 a has a gradation part 2 c in the vicinity of the instruction part tip 26 and gradually disappears toward the instruction part 21. By being formed in this way, even if there is a deviation in the alignment between the indicator tip 26 and the indicator image 2a due to manufacturing variations, the sense of unity between the indicator 21 and the indicator image 2a is impaired. Can be prevented.

  A third embodiment of the present invention will be described. As shown in FIG. 11, a tip light receiving portion 28 having a pointing portion tip 26 formed substantially parallel to the surface direction of the dial plate 3 is provided, and the pointing portion image 2a is displayed up to a position below the tip light receiving portion 28. Light for displaying the partial image 2a can be received by the tip light-receiving unit 28, and the colored layer 29 provided in the instruction unit 21 can be illuminated to emit light. By forming the pointer light source 43 in this way, the indicator 21 can be caused to emit light without using the light of the pointer light source 43, so that the number of parts of the pointer light source 43 can be reduced and the cost can be reduced.

  The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the gist of the present invention.

  For example, in the above-described embodiment, the liquid crystal display module 1 is not limited to the TFT type liquid crystal, but may be a multi-dot or segment type, and may be a single color display or a full color display. The liquid crystal display module 1 may be an EL (Electro Luminescence) module. Further, although the liquid crystal display module 1 and the circuit board 4 are energized by the FPC 11, they may be lead wires, conductive rubber, or the like. Moreover, although LED was used as the pointer light source 43 and the dial light source 44 which are illumination means, other illumination means may be used.

  Although the liquid crystal see-through part 3a is the transparency of the base material 31, a smoke ink layer such as a smoke color may be provided in the printing opening 32. Moreover, although the liquid crystal see-through | perspective part 3a was the seamless specification which left the base material 31, it may be a through-hole.
