Japanese Patent Laid-Open No. 2006-232128

  In a vehicle such as an automobile, an electronic device to be mounted, for example, an air conditioner, a car audio system, and an operation unit for operating a car navigation system are provided, for example, in a vehicle instrument panel portion. The operation unit is provided with an operation unit for a vehicle occupant to operate as necessary. Among these, dial type operation devices are often used in air volume adjustment operation units, temperature adjustment operation units or outlet selection operation units of air conditioners, volume operation units of car audio systems, and the like (Patent Document 1).

  Such a dial type operation device is often configured with a pointer that moves according to the rotational operation angle position of the dial operation unit in order to indicate each set value and each set state.

  In the conventional case, since a pointer that moves according to the rotational operation angle position of the dial operation unit is provided, a light receiving unit (light guide prism) that guides the light transmitting unit of the pointer is provided, and a position facing the light receiving unit The light guide prism is disposed on the rear surface of the light guide prism, and one light source is disposed on the back side of the light guide prism. Then, as the pointer rotates, the light receiving portion of the pointer rotates on the light guide prism, and the light from the light source is set to be introduced into the light receiving portion through the prism. As a result, the light transmitting portion of the pointer Lights up. However, when the light receiving part of the pointer is located near the light source via the prism, a lot of light is introduced into the light receiving part, but when the light receiving part is located away from the light source, the light receiving part is received. The amount decreases. As described above, when the indication position of the pointer changes, the brightness of the transparent portion of the pointer changes.

  An object of the present invention is to provide an in-vehicle electronic device operating device that does not change the brightness of a translucent unit that indicates the rotational operation angle position of a dial operating unit.

Means for Solving the Problems and Effects of the Invention

The present invention relates to an in-vehicle electronic device operating device that is used by being installed in a vehicle to operate an in-vehicle electronic device.
A hollow dial operation unit arranged so as to be rotatable around an operation axis intersecting with the front of the device;
By receiving light from a display light source arranged inside the dial operation unit, the display translucent unit that exhibits a different translucent form for each angular position around the operation axis is rotated in the circumferential direction of the dial operation unit. And an angular position display board in which the background region of the display light transmitting portion is formed of a light transmission suppressing material having a light transmission lower than that of the constituent material of the display light transmitting portion.
It has an instruction light source fixedly arranged at a predetermined angular position around the operation axis of the dial operation unit, and is positioned relatively to an arbitrary angular position on the angular position display panel as the dial operation unit is rotated. And an operation angle position instruction unit for instructing lighting so that the operation angle position of the dial operation unit can be read by the instruction light source in accordance with the instruction position with respect to the angle position display board,
It is characterized by providing.

  According to the above-described configuration of the present invention, instead of the conventional rotation pointer, the non-rotating operation angle position instruction unit instructs to turn on the operation angle position of the angle position display panel of the dial operation unit. At this time, since the lighting instruction position by the operation angle position instruction unit is at a fixed position without rotating, it can be lighted uniformly without unevenness so that there is no difference in brightness.

  In addition, the light transmission suppression material in an angle position display board can be used as a light shielding material. This makes it possible to clearly identify the display translucent portion and its background region.

  The operation angle position instructing section in the present invention can be formed in the dial operation section. The operation angle position indicating unit can be provided with an angle position indicating light-transmitting unit that is turned on by receiving light from an instruction light source disposed inside the dial operation unit. According to this configuration, the instruction light source can be provided inside the dial operation unit in the same manner as other display light sources, which can contribute to space saving of the in-vehicle electronic device operation device.

  Further, in the operation angle position instruction section, the instruction light source can be arranged at a position directly below the angle position display board in the rotational radius direction of the dial operation section. In this case, the display light-transmitting portion of the angular position display panel that is aligned with the indicating light source is configured to receive light from the indicating light source, and the aligned display transmitting light The portion can be in an enhanced translucent state for emphasizing and identifying the remaining display translucent portion irradiated by the display light source. In other words, the display translucent part that receives light from the instructing light source can also be used as the angular position indicating translucent part. Since there is no need to provide the angular position indicating light transmitting portion, the structure is further simplified and the cost is reduced.

  Further, in this case, since the indication light source can have a light emission color different from that of the display light source, the emphasized light transmission state of the display light transmission portion that is also used as the angular position indication light transmission portion is the remaining It can be defined as a lighting color different from the display translucent part. Since the color difference is provided between the angle position indicating translucent part and the display translucent part, it is easy to recognize the operation angle position of the dial operation part, that is, the setting state of the dial operation part. More specifically, the instruction light source may have a red emission color, and the display light source may have a blue emission color, a green emission color, or a white emission color.

  On the other hand, the indication light source has the same emission color as the display light source, and the emphasized light transmission state of the display light transmission portion that is also used as the angular position indication light transmission portion is the remaining display light transmission portion. It can also be determined to exhibit different lighting amounts. Since a difference in brightness is provided between the angle position indicating translucent section and the display translucent section, it becomes easy to recognize the operation angle position of the dial operation section, that is, the setting state of the dial operation section.

  The dial operation unit according to the present invention can be configured so that it can be rotated stepwise in a predetermined operation angle unit. On the angular position display board, a plurality of display figures each forming a display translucent portion can be discretely formed at an angular interval that matches the operation angle unit, and further, a display light source A plurality of objects individually corresponding to the display graphic can be fixedly arranged at an angular interval that coincides with the operation angle unit along the rotational circumferential direction of the dial operation unit. According to this configuration, the display translucent section and the display light source can be appropriately arranged in accordance with the dial operation section that can be rotated in stages.

  In this case, the display light-transmitting part that receives light from the instruction light source is also used as the angular position indicating light-transmitting part, so that the instruction light source is arranged on the array path of the plurality of display light sources. Thus, one of the display light sources can be replaced. According to this configuration, while omitting one of the display light sources fixedly arranged at an angular interval that matches the operation angle unit along the rotational circumferential direction of the dial operation unit, the number of parts is reduced and the number of parts is omitted. The display translucent part irradiated by the instruction light source instead of the light source can be an angular position instruction translucent part.

  The display light source according to the present invention is configured so that the dial operation unit is moved leftward from the angular position of the display graphic located at the right end of the angle position display panel when the dial operation unit is operated to the right operation limit angle position. When the operation is performed up to the operation limit angle position, it can be arranged at an angle interval that matches the operation angle unit over the entire section up to the angle position of the display graphic positioned at the left end of the angle position display board. Thereby, the arrangement angle section length of the display graphic in the angle position display board is set shorter than the arrangement angle section length of the display light source. In this case, in the dial operation portion, the remaining section portion excluding the array angle section of the display graphic in the rotation circumferential direction can be formed as a light shielding portion. According to this configuration, even when the dial operation unit is operated up to the left and right operation limit positions, all the display figures are lit, so all the dial operation units are in any operating angle position. A figure can be easily visually recognized.

  The angular position display board in the present invention can be formed on the front wall of the dial operation unit in the operation axis direction. In this case, a light-shielding partition wall is formed on the back surface of the front surface wall so as to extend rearward in the operation axis direction and to partition a plurality of display figures from each other in the rotational circumferential direction of the dial operation portion. be able to. According to this configuration, each display graphic can block light emitted from a light source adjacent to the light source while receiving light irradiation from a light source located behind the display graphic. For this reason, each display figure can be lighted uniformly and uniformly so that there is no difference in brightness.

  In addition, the dial operation part is positioned outside the display graphic of the angular position display panel in the rotational radius direction and is formed to extend rearward in the operation axis direction along the rotational circumferential direction of the dial operation part. And an inner peripheral wall portion that is located inside the display graphic of the angular position display board and extends rearward in the operation axis direction along the rotational peripheral direction of the dial operation portion. can do. Furthermore, each light-shielding partition wall can be integrally formed by connecting the outer peripheral wall portion and the inner peripheral wall portion in the rotational radius direction. According to this configuration, each display graphic is irradiated with light only from the light source located behind the display graphic. For this reason, each display figure can be lighted uniformly and uniformly so that there is no difference in brightness.

  In the present invention, at least one of the instruction light source and the display light source can be used as a fluorescence excitation light source. In this case, among the instructing translucent part and the display translucent part, the part that receives the fluorescence excitation light from the fluorescence excitation light source can be made of a composite translucent material in which a fluorescent material is dispersed. According to this structure, it can be set as the lighting state in the form which self-light-emits the instruction | indication translucent part and the display translucent part.

The light source corresponding to the translucent part at the predetermined operation angle position of the operation unit is turned on to display the predetermined operation angle position of the operation unit by lighting the translucent part. It can also be set as the structure to do.

  According to the configuration of the present invention, when the dial operation unit is rotated, the translucent part at the predetermined operation angle position is turned on by the light source, and the operation angle position is displayed on the translucent part. Therefore, the translucent part can be lit uniformly without uneven brightness. For this reason, a light guide prism and a special pointer light source are not required, and the structure can be simplified and the manufacturing cost can be reduced.

  In the plurality of light sources, the light source corresponding to the light transmitting part at the predetermined operation angle position of the operation part is set so that the emission color is different from other light sources corresponding to the light transmitting part different from the light transmitting part. When all of the plurality of light sources are turned on, the light source corresponding to the light transmitting portion at the predetermined operation angle position of the operation unit is set to be recognized in a different color with respect to the other light sources. Can be configured. According to this configuration, when all of the plurality of light sources are turned on, the light source corresponding to the light transmitting portion at the predetermined operation angle position of the operation unit is set to be recognized in a different color with respect to the other light sources. Therefore, since the translucent part at the predetermined operation angle position of the dial operation part is lit in a different color with respect to the other translucent parts, the translucent part at the predetermined operation angle position can be reliably recognized. .

  Further, in the configuration of the present invention, when the night control signal control unit and the lighting control unit are provided and a signal indicating that it is nighttime is input from the night control signal control unit to the lighting control unit, another light source Can be configured to light up. According to this configuration, at night, the translucent part at the predetermined operation angle position of the dial operation part is lit in a different color with respect to the other translucent parts. On the other hand, when it is not nighttime, only the translucent part at the predetermined operation angle position of the dial operation part can be turned on.

  The light sources 6 and 7 are preferably provided in association with the display translucent part 24, but are necessarily arranged at a position directly below the display translucent part 24 in the rotational radius direction of the dial operation unit 2. There is no need. For example, as shown in FIG. 9, it can arrange | position in the form which has directivity in the direction in which each translucent part 24 for display is formed.

  Further, the display light sources 6 do not have to be formed in the same number as the display translucent parts 24, and only one display light source 6 is arranged immediately below the center position of the dial operation part 2 as shown in FIG. 10. The whole display translucent portion 24 may be illuminated. In this case, the number of light sources can be reduced. In this case, the indication light source 7 can be fixedly arranged so that one of the display translucent parts 24 is illuminated together with the display light source 6. When the influence of light mixing is taken into consideration, the light from the display light source 6 may be blocked by the light blocking wall 40.

  In addition, the operation angle position of the dial operation unit 2 can be indicated by a figure other than the display translucent unit. For example, in addition to the display translucent unit 21 that displays each angular position of the dial operation unit 2, an instruction graphic 21 a that indicates each display graphic 21 is formed corresponding to each display translucent unit 21. The operation angle position of the dial operation unit 2 can be indicated by the instruction graphic 21a. As a specific example, as shown in FIG. 11, an instruction graphic 21 a is formed on the outer peripheral side of the display graphic 21, and the instruction light source 6 is arranged at a position directly below the display unit 20 in the rotational radius direction of the dial operation unit 2. Then, the instruction graphic 21 a that is aligned with the instruction light source 6 is configured to be illuminated by the instruction light source 6. In this case, the instruction graphic 21 a illuminated by the instruction light source 6 is lit in an emphasized light transmission state different from the remaining instruction graphic 21 a and the display light transmission part 21, and indicates the operation angle position of the dial operation unit 2. To do.

  Further, at least one of the instruction light source 6 and the display light source 7 is used as a fluorescence excitation light source, and the fluorescence excitation light is emitted from the fluorescence excitation light source among the instruction light transmission unit 29 and the display light transmission unit 21. The material that receives the light can be formed of a composite light-transmitting material in which a fluorescent material is dispersed. For example, as shown in FIG. 12, the instruction light source 6 is a fluorescence excitation light source, the display light source 7 is a visible light source, and the total light transmission portion 21 (29) is made of a composite light transmission material in which a fluorescent material is dispersed. Can be formed. As a result, the instructing translucent section 29 is in a self-luminous lighting state (FIG. 12B), and the other display translucent sections 21 output the visible light of the display light source 7 in the same color. (Fig. 12 (c)). Thereby, both lighting colors can be made different. In addition, in the instruction light source 6 and the display light source 7, the fluorescence excitation light source and the visible light source may be interchanged. Moreover, UVLED can be used as a light source for excitation.
