  By the way, in the combination meters 1 and 11 shown in FIG. 5 and FIG. 6, during normal time (non-emergency), the meter user (driver) mainly uses a pair of analog display meter sections 3, 4, 13, and 14. The display information is frequently checked. In the case of the combination meter 1 shown in FIG. 5, the distance L1 between the pair of analog display meter portions 3 and 4 is large, so that each meter portion is checked. In this case, a large movement of the line of sight is required, and there is a problem that the visibility with respect to these analog display meter sections 3 and 4 is lowered.

  Also, since there is usually little information to be displayed on the digital display section, if the digital display section has a large display area, the actual information display area can be utilized only a very small part of the large screen. As a result, the problem of poor appearance also occurred.

  On the other hand, in the case of the combination meter 1 shown in FIG. 6, since the distance L2 between the pair of analog display meter portions 13 and 14 is small, the line of sight movement when checking these meter portions can be small. Good visibility can be secured in the analog display meter sections 13 and 14. However, in the event of an emergency in which emergency information such as a warning regarding a failure occurring in each part of the vehicle is displayed, sufficient information cannot be displayed because the display area of the digital display unit 16 is small, and the digital display unit 16 Since this is a special shape, it is difficult to visually display the emergency information to be provided, and there is a problem that the display performance of the digital display unit 16 in an emergency is low.

That is, in the combination meters 1 and 11 shown in FIG. 5 and FIG. 6, in the combination meter, the visibility of the pair of analog display meter sections in the normal time and the display performance of the digital display section in the emergency are improved. There was a problem that it was impossible to achieve both.
Further, there is a similar problem not only when information is displayed in an emergency but also when the driver needs a large amount of information. Currently, the information displayed on the digital display section includes travel distance (odd, trip), automatic transmission position (PRNDL), fuel amount, cooling water temperature, outside air temperature, eco information, audio related information, etc. In the future, in addition to these, it may be possible to display navigation system, air conditioner information, information provided on the Internet, and the like.

  Furthermore, when the digital display unit has a large display area during normal times when the information displayed on the digital display unit is small, only a very small part of the large screen is used for actual information display. Since the size of the area that does not exist is conspicuous, there also arises a problem that it does not look good as a display.

  Patent Document 1 discloses a configuration in which a visible area of a digital display unit is changed by bringing a pair of analog display meter units arranged on both sides of the digital display unit close to each other or apart from each other. Yes. However, simply changing the visible area of the digital display unit cannot enhance the information given to the driver, resulting in poor visibility.

  An object of the present invention is to solve the above-mentioned problems, and it is possible to improve the visibility of a pair of analog display meter units in a normal state and to perform digital at a predetermined time such as an emergency or when a driver needs a large amount of information. The display performance of the display unit can be improved, and the display area of the digital display unit can be reduced during normal times when the amount of information displayed on the digital display unit is reduced, improving the appearance of the display. It is to provide a combination meter that can be used.

The above-described object of the present invention is achieved by the following configuration.
(1) A pair of left and right analog display meters for displaying the detected value in an analog manner
A digital display unit disposed between the pair of analog display meter units to display information;
A combination meter comprising:
An advance / retreat drive mechanism for moving each analog display meter portion forward / backward on an inclined axis inclined in the line-of-sight direction from the eye point of the meter user;
An illumination mechanism that can distribute illumination light to a transmission hole that is provided behind the dial of each analog display meter unit and is formed in the periphery of the dial or the dial;

When the information amount or information content to be displayed on the digital display unit is predetermined, at least one of the analog display meter units advances or retracts the analog display meter unit to a position that covers or does not cover the digital display unit,
The illumination mechanism distributes illumination light in a state where at least a part of the analog display meter unit covers the digital display unit.

  (2) The advancing / retreating drive mechanism moves the pair of analog display meter units at a normal time when the amount of information to be displayed on the digital display unit is small, and a part of each analog display meter unit is moved to the front side of the digital display unit. When a large amount of information is formed to cover the normal display state and the digital display unit displays a large amount of information, the analog display meter unit moves the pair of analog display meter units away from the center of the meter. The combination meter according to the above (1), wherein a display state when there is a large amount of information that does not overlap on the digital display unit is formed.

(3) In a state where a large amount of information is displayed in which the analog display meter unit does not overlap the digital display unit, a light shielding member is close to the periphery of each analog display meter unit, and the light distribution by the illumination mechanism is in front of the meter. The combination meter according to the above (1), wherein leakage into the device is suppressed.

  (4) The combination meter according to (3), wherein the light shielding member is a meter case of the combination meter.

  (5) The combination meter according to any one of (1) to (4), wherein the illumination mechanism is provided in the analog display meter unit.

  (6) The combination meter according to any one of (1) to (4), wherein the illumination mechanism is provided in a meter case of the combination meter.

  According to the configuration of (1), at the normal time when the amount of information to be displayed on the digital display unit is small, at least one analog display meter unit can be moved to a position closer to the meter center side. As a result, the distance between the analog display meter sections becomes small, and even if the confirmation operation for the display information on the pair of analog display meter sections frequently occurs, the movement of the line of sight is small, and the pair of analog display Good visibility can be obtained for the meter portion.

  In addition, a digital display unit that can be visually recognized by the user is usually arranged by covering a part of at least one analog display meter unit moved to a position closer to the meter center side on the digital display unit. The display area of is reduced. Therefore, even if there is little information to be displayed on the digital display unit, a vacant area that cannot be used for information display is not so noticeable, and the appearance as a display can be improved.

  Furthermore, when the amount of information or information content to be displayed on the digital display unit is predetermined, at least one analog display meter unit is moved away from the digital display unit so that the analog display meter unit does not overlap the digital display unit. Can be. Thereby, the digital display part will be in the display state which expanded the display area, and can obtain the high display performance which can display more information.

  Here, when the amount of information and the information content are predetermined, for example, when the information content is emergency information or when there is a lot of information requested by the driver (for example, fuel consumption, cruising range, multiple trips, departure time) For example, when it is desired to display the elapsed time since, etc.

  Further, according to the configuration of (1) above, when the amount of information to be displayed on the digital display unit is small, at least one analog display meter unit is on an inclined axis inclined in the line of sight from the eye point of the meter user. When the meter is moved forward to the meter user side, it moves to a position closer to the meter center side, so that at least one analog display meter unit is closer to the meter user side than the digital display unit, For a person, at least one of the analog display meter portions is enlarged and emphasized, and the visibility with respect to at least one of the analog display meter portions is further improved.

  In addition, when the amount of information and the information content to be displayed on the digital display unit are predetermined, at least one analog display meter unit is on the side opposite to the meter user on the tilt axis inclined in the line-of-sight direction from the meter user's eye point. By moving backward, it moves away from the center of the meter to a position that does not overlap the digital display, so the digital display is relatively closer to the meter user than at least one analog display meter. Thus, the digital display portion is highlighted so as to be lifted. Therefore, the meter user can be prompted to confirm the information displayed on the digital display unit, and the visibility on the digital display unit can be further improved.

  In addition, in any case of switching to the normal display state, or when the amount of information to be displayed or the information content is switched to the predetermined display state, at least one of the analog display meter units is a line of sight from the eye point of the meter user. Because it moves on the tilt axis tilted in the direction, the movement of the line of sight from the eye point to each analog display meter can be suppressed very slightly, and the analog display meter can be visually recognized during the movement of the analog display meter. It can prevent that property falls.

  Therefore, according to the configuration of the above (1), both the improvement of the visibility of the pair of analog display meter units at the normal time and the improvement of the display performance of the digital display unit when the information amount and the information content to be displayed are predetermined. In addition, the display area of the digital display unit can be reduced in normal times, and the appearance and visibility as a display can be improved.

  Further, according to the configuration of (1), normally, the peripheral edge of the analog display meter portion positioned so as to protrude toward the meter user side from the digital display portion or the transmission hole formed in the dial Further, the illumination light is distributed by the illumination mechanism provided behind the dial of the analog display meter unit, so that the width of light leaking from the periphery of the analog display meter unit with the movement of the analog display meter unit is reduced. Change. As a result, it is possible to provide a novel visual effect as if the dial is floating in the air. As a result, it is possible to produce a floating feeling and to improve the design of the analog display meter unit. Can do.

  According to the configuration of (2) above, the digital display unit and the analog display meter unit are respectively used in a normal time when the amount of information displayed on the digital display unit is small and in a large amount of information displayed on the digital display unit. It can be operated effectively.

According to the configuration of (3) above, when the analog display meter unit is in a display state when there is a large amount of information such as an emergency display state and the digital display unit does not overlap , the light shielding member is close to the peripheral portion of the analog display meter unit Since the light distribution from the illumination mechanism installed behind the dial of the analog display meter section is prevented from leaking to the front of the meter, the dial of the analog display meter section appears to be floating in the air. The effect is reduced, thereby making it easier to transfer the line of sight to the digital display unit as much as the analog display meter unit becomes inconspicuous, and the visibility of information on the digital display unit can be improved in an emergency.

  According to the configuration of (4) above, since the light shielding member is a meter case of a combination meter, it is possible to carry out appropriate light shielding without newly using parts, preventing an increase in the number of parts and an increase in manufacturing costs. can do.

  According to the configuration of (5) above, wiring to the analog display meter unit can also be used as a light source, so wiring to the illumination mechanism is easy.

  Hereinafter, a preferred embodiment of a combination meter according to the present invention will be described in detail with reference to the drawings.

[First Embodiment]
1-3 is explanatory drawing of 1st Embodiment of the combination meter which concerns on this invention.

  The combination meter 21 shown in FIG. 1 to FIG. 3 includes a pair of left and right analog display meter sections 23 and 24 for displaying detected values in an analog manner on one meter panel 22, and a pair of these analog display meter sections 23. , 24 and a digital display unit 26 arranged at the center of the meter, which can display a large amount of information.

  In the following description, emergency information such as a warning will be described as an example of a large amount of information displayed by the digital display unit 26 other than normal times. However, as a large amount of information displayed other than normal times, fuel consumption and cruising are possible. Information that collectively displays distance, a plurality of trips, an elapsed time since departure, and the like may be used.

  The combination meter 21 is provided in the instrument panel of the vehicle and displays various detection values indicating the operation state of the vehicle. The analog display meter unit 23 is a pointer 23b that is driven to rotate on the dial 23a. The analog display meter unit 24 is a tachometer that displays the engine speed by a pointer 24b that is rotationally driven on the dial 24a.

The digital display unit 26 uses, for example, a liquid crystal display. When emergency information such as a warning about a failure occurring in a part such as an in-vehicle device or an engine is generated, the digital display unit 26 displays the information in characters, graphics, or the like. In addition, the digital display unit 26 is also used for displaying the travel distance data 25 that can be displayed with a small display area as shown in FIG.
A graphic 27 displayed on the digital display unit 26 in FIG. 2A indicates the occurrence of an engine trouble.

  In the case of the combination meter 21 of the present embodiment, the digital display unit 26 has a sufficient display area so that various information displayed in an emergency can be easily displayed on a rectangular display screen.

Further, as shown in FIGS. 1 (b) and 2 (b), each analog display meter unit 23, 24 is moved from the eye point of the meter user by an advancing / retreating drive mechanism 33 provided for each meter. It is supported so as to be able to advance and retreat on the inclined axes k1, k2 inclined in the direction of the line of sight i1, i2.
Further, in the case of the present embodiment, an illumination mechanism 51 capable of distributing illumination light around the dials 23a, 24a is provided behind the dials 23a, 24a of the analog display meter units 23, 24.

  If structurally possible, the tilt angles of the tilt axes k1 and k2 are preferably matched with the line of sight i1 and i2 from the standard eyepoint position set based on statistics and the like in advance. However, in practice, it is difficult to uniquely determine the line of sight i1, i2 from the standard eye point position, and there is a restriction on the structure, so the included angle θ with the line of sight i1, i2 is equal to or less than a predetermined value. Set the tilt angle appropriately. Here, the included angle θ is preferably as small as possible.

  The advancing / retracting drive mechanism 33 includes a frame 35 that supports the analog display meter sections 23 and 24, and a guide shaft that is coupled to the frame 35 and that is supported on the meter case 36 side so as to be movable along the inclined axes k1 and k2. 37, a rack 38 coupled to the frame 35 in parallel with the guide shaft 37, and a motor 41 that rotationally drives a pinion 39 that meshes with the rack 38. The motor 41 rotates the pinion 39 forward and backward. By doing so, the analog display meter sections 23 and 24 are moved back and forth along the tilt axes k1 and k2.

  In the case of the combination meter 31 of the present embodiment, during a normal time when the amount of information to be displayed on the digital display unit 26 is small, the pair of analog display meter units 23 and 24 moves to the eye point side on the tilt axes k1 and k2. As shown in FIG. 1, the analog display meter unit 23, 24 is moved to a position closer to the center of the meter so that a part of each analog display meter unit 23, 24 is covered on the digital display unit 26. The normal display state in which the display area of 26 is reduced.

Further, in an emergency where a large amount of information is displayed on the digital display unit 26, the pair of analog display meter units 23 and 24 are shown in FIG. 2 by moving on the tilt axes k1 and k2 in a direction away from the eye point. Thus, the analog display meter sections 23 and 24 are arranged so as not to overlap the digital display section 26, and the digital display section 26 enters an emergency display state in which the display area is expanded.
Here, the pair of analog display meter sections 23 and 24 may be driven simultaneously, may be driven separately, or only one of them may be driven.

  In the present embodiment, as shown in FIGS. 1B and 1C, the illumination mechanism 51 includes a reflection surface 53 on the inner bottom portion of the meter case 36 that houses the analog display meter portions 23 and 24, and each meter portion. The light source 56 is attached to the wiring board 54 fixedly provided on the back side of the heads 23 and 24 and emits the illumination light 55 toward the reflection surface 53. As the light source 55, for example, an LED (light emitting diode) having a long lifetime is used.

  In the case of the present embodiment, the illumination mechanism 51 controls the lighting of the light source 56 by, for example, a control circuit mounted on the wiring board 54, and at least in the normal time, as shown in FIG. Illumination light 55 is distributed around the periphery of 24a.

  In FIG. 3A, in order to clarify the illumination effect by the illumination mechanism 51, the illumination mechanism 51 provided in one of the analog display meter sections 23 and 24 turns on the light source 56. However, the illumination mechanism 51 provided in the other analog display meter unit 24 does not light the light source 56.

  As shown in FIG. 3 (a), one analog display meter unit 23 that performs light distribution by the illumination mechanism 51 in the normal display state distributes light by illumination light 55 on the outer peripheral portion of the dial 23a. A light emitting area 57 that emits bright light is formed. The light emitting area 57 can provide a novel visual effect as if the dial 23a is floating in the air, and can improve the design of the analog display meter unit 23.

  On the other hand, in the case of the analog display meter unit 24 in which the light distribution by the illumination mechanism 51 is not performed, the peripheral portion on the outer side of the dial 24 a becomes a dark part 58, which is visually compared with the analog display meter unit 23. The impact is poor, and the effect of light distribution by the illumination mechanism 51 is clear.

  Further, in the case of the present embodiment, in the emergency display state shown in FIG. 2, the inner surface 59 of the meter case 36 that is a light shielding member is close to the periphery of each analog display meter unit 23, 24, and the illumination mechanism 51. Is prevented from leaking to the front of the meter. As a light shielding member for preventing the illumination light 55 from leaking close to the periphery of each analog display meter section 23, 24 in an emergency display state, a dedicated light shielding plate is attached in the meter case 36. Also good.

  As a result, in the emergency display state, even if the light source 56 of the illumination mechanism 51 remains on, a light emission area 57 may be formed around the dials 23a and 24a of the analog display meter units 23 and 24. Therefore, the analog display meter sections 23 and 24 are not visually emphasized. Therefore, relatively, in the emergency display state, the digital display unit 26 becomes conspicuous, and the visibility to the digital display unit 26 is improved.

  According to the configuration of the combination meter 21 described above, when the amount of information displayed on the digital display unit 26 is small, as shown in FIG. Since the distance between the analog display meter units 23 and 24 is small, even if the confirmation operation for the display information on the pair of analog display meter units 23 and 24 frequently occurs. The movement of the line of sight is small, and good visibility can be obtained for the pair of analog display meter portions 23 and 24.

  Further, in a normal state, a part of each analog display meter unit 23, 24 moved to a position closer to the center side of the meter is covered on the digital display unit 26 so that the digital display can be visually recognized by the user. The display area of the part 26 is reduced. Therefore, even if there is little information to be displayed on the digital display unit 26, a vacant area that cannot be used for information display is not so noticeable, and the appearance as a display can be improved.

  Further, in an emergency in which the amount of information displayed on the digital display unit 26 increases, as shown in FIG. 2, the pair of analog display meter units 23 and 24 move away from the center of the meter, and the analog display meter unit 23, 24 is arranged so as not to overlap the digital display unit 26. Thereby, the digital display part 26 will be in the emergency display state which expanded the display area, and can obtain the high display performance which can display more information.

  Therefore, according to the configuration of the combination meter 21, it is possible to improve both the visibility of the pair of analog display meter portions 23 and 24 in a normal state and the display performance of the digital display portion 26 in an emergency. In addition, the display area of the digital display unit 26 can be reduced during normal operation to improve the appearance of the display.

  Further, in the combination meter 21 of the present embodiment, during a normal time when the amount of information displayed on the digital display unit 26 is small, the pair of analog display meter units 23 and 24 moves forward on the tilt axes k1 and k2 as shown in FIG. Therefore, the pair of analog display meter sections 23 and 24 are pushed closer to the meter user side than the digital display section 26. Therefore, for the meter user, the pair of analog display meter portions 23 and 24 are enlarged and emphasized, and the visibility to the pair of analog display meter portions 23 and 24 is further improved.

In an emergency where the amount of information displayed on the digital display 26 increases, the pair of analog display meter sections 23 and 24 move away from the center of the meter as shown in FIG. 2 by moving backward on the tilt axes k1 and k2. Since the digital display unit 26 moves backward to a position that does not overlap the digital display unit 26, the digital display unit 26 is relatively closer to the meter user side than the pair of analog display meter units 23 and 24. Will be highlighted.
Therefore, the meter user can be prompted to confirm the emergency information displayed on the digital display unit 26, and the visibility on the digital display unit 26 can be further improved.

  Further, in the combination meter 21 of the present embodiment, the analog display meter sections 23 and 24 are moved from the eye point of the meter user when switching to the normal display state or when switching to the emergency display state. Therefore, the movement of the line of sight from the eye point to each of the analog display meter units 23 and 24 can be suppressed very little, and the analog display meter units 23 and 24 are moved. It is possible to prevent the visibility to the analog display meter sections 23 and 24 from being lowered during the moving operation.

  Further, in the combination meter 21 of the present embodiment, normally, the analog display meter portions 23 and 24 that are positioned so as to protrude from the digital display portion 26 toward the meter user side are provided with these analog portions. The illumination light 51 is distributed by the illumination mechanism 51 provided behind the dials 23a and 24a of the display meter units 23 and 24, so that a light emission area 57 is formed, as if the dials 23a and 24a float in the air. As a result, a novel visual effect can be provided, and the design of the analog display meter units 23 and 24 can be enhanced.

Furthermore, in the case of the combination meter 21 of the present embodiment, in the emergency display state shown in FIG. 2, the inner side surface 59 of the meter case 36, which is a light shielding member, indicates that the illumination light 55 from the illumination mechanism 51 leaks to the front of the meter. It comes to deter. Therefore, even if the light source 56 of the illumination mechanism 51 is kept on, the light emission area 57 is not formed around the dials 23a and 24a of the analog display meter sections 23 and 24, and the analog display is visually performed. The meter parts 23 and 24 are not emphasized. Therefore, relatively, in the emergency display state, the digital display unit 26 becomes conspicuous, and the visibility to the digital display unit 26 can be further improved.
Furthermore, in the case of the combination meter 21 of the present embodiment, the wiring to the analog display meter sections 23 and 24 can be used for the light source 56, so that the wiring to the illumination mechanism 51 is easy.

[Second Embodiment]

  The combination meter 31 shown in FIG. 4 is equipped behind the dials 23a and 24a of the analog display meter units 23 and 24, and is capable of distributing illumination light to the periphery of the dials 23a and 24a. The other configuration may be the same as that of the combination meter 21 of the first embodiment, and the same components are denoted by the same reference numerals and description thereof is omitted.

  In the combination meter 31 of the second embodiment, the illumination mechanism 51 has a light source 56 disposed on the reflection surface 53 on the inner bottom portion of the meter case 36 that accommodates the analog display meter portions 23 and 24. The light source 56 is mounted on the reflecting surface 53 so as to emit the illumination light 55 toward the peripheral portions of the dials 23a and 24a.

  In the case of the second embodiment, the light source 56 of the illumination mechanism 51 is fixed on the meter case 36 which is a large fixed part, and thus the light source 56 is mounted on the analog display meter parts 23 and 24 which are movable parts. Compared with the case of the first embodiment, the degree of freedom of arrangement of the light source 56 is increased, and the illumination mechanism 51 can be easily equipped.

  The present invention is not limited to the above-described embodiments, and can be appropriately modified and improved. In addition, the material, shape, dimension, numerical value, form, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
