Description

  The present invention relates to a pointer used in a meter device mounted on various vehicles such as a vehicle, a ship, and an aircraft, and more particularly to an illumination structure of a pointer that realizes light emission illumination.

  Conventionally, in this type of meter device mounted on a vehicle or the like, generally, a dial plate provided with letters, numbers, scales, etc. is illuminated from the back side with a light source or the like, It is common to illuminate the pointer itself that points to numbers.

  That is, as the latter meter device, various self-luminous types have been developed. One of them is known to improve the luminous efficiency of the pointer (see, for example, Patent Document 1).

  As shown in FIG. 8, the meter device 100 includes a motor case 101, a pointer 102 guided through a protruding portion 101 </ b> A provided on the main body of the motor case 101, and a pointer shaft provided integrally with a base portion of the pointer 102. 103, a light source 105 disposed immediately below the hollow shaft 104, away from the lower end portion 103 </ b> A of the pointer shaft 103, and a printed circuit board 106 on which the light source 105 is mounted.

  In the meter device 100, the pointer shaft 103 integral with the pointer 102 has a convexly-converged condensing surface at the lower end 103A in order to efficiently collect illumination light emitted from the light source 105 made of LED. The pointer shaft 103 has a cylindrical shape, and its lower end 103A has a hemispherical shape or a convex shape. According to the pointer 102 having such a specific shape, the illumination light from the light source 105 made of LED can be made to travel in parallel with the axis after being incident on the pointer shaft 103. In this meter device, dial illumination is performed by disposing a plurality of dedicated light sources (not shown) below the dial (not shown).

  In addition, the pointer 102 of the meter device 100 effectively illuminates the illumination light guided from the light source 105 to the pointer shaft 103 to the tip. Therefore, the reflecting surface 102B is formed on the pointer 102 in order to reflect and deflect the illumination light guided by the pointer shaft 103 provided integrally therewith in a substantially right angle direction. Furthermore, in order to avoid the trouble that a part of the illumination light guided to the pointer 102 goes straight upward from the base and leaks outside to the outside of the viewer's eyes, the pointer 102 is shielded from light. The cap 107 is put on.

  By the way, in the meter apparatus for vehicles etc., the thing of the structure provided with the above self-light-emitting type pointers is common. However, according to such guidelines, it is not a simple self-luminous type lighting as described above, but it is differentiated from other things and upgraded by giving it an unprecedented novelty. It is desired to develop an illumination structure for the pointer that can be used.

  Therefore, for example, a guideline as described in Patent Document 2 has also been proposed. That is, as shown in FIG. 9, the pointer 200 has a metal plating film 202 formed on the side surface and the lower surface of the pointer main body 201, and a metal plating film 203 having a substantially V-shaped cross section on the upper surface of the pointer main body 201. Is formed.

Special table 2009-537844 JP-A-9-96680

  In the guideline described in Patent Document 2, the design is improved by forming a metal plating film 203 having a V-shaped cut in the upper surface of the main body as compared with a normal guideline. It can give a sense of quality compared to general guidelines. However, the pointer main body 201 lacks the sharpness of the illumination portion and the like, and lacks lightness in terms of design. In other words, there is a need for a novel lighting structure that is unprecedented in modern, unique, and further differentiated from the guidelines.

  The present invention has been made in view of the above-described circumstances, and the purpose thereof is to provide a sharp and novel impression of the illumination part, and thus to improve the quality, and to have high design.

Illumination can be performed with high brightness. As a result, it is possible to avoid that the illumination light directly enters the eye of the viewer in a state of high brightness and gives the eyes a stimulus.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
(First embodiment)
FIG. 1 shows a meter device 10 to which the illumination structure of the pointer according to the first embodiment of the present invention is applied. The meter device 10 includes a light source 2 mounted on a substrate 1, a rotating shaft 4 that rotates when a driving force of a motor (not shown) housed in a motor case 3 is transmitted, and a tip of the rotating shaft 4. Necessary information on the vehicle itself or the environment around the vehicle, such as the pointer 6A that is fitted and rotated integrally with the rotary shaft 4, the cap 7 that is put on the base 62 of the pointer 6A, and numerals, characters, symbols, etc. And a dial 5 for displaying.

  The meter device 10 according to the present embodiment constitutes a part of a combination meter, and the periphery is covered with a turntable plate (not shown). Further, the dial plate 5 is opened with various display windows for installing various instruments including the meter device 10.

  The meter device 10 of the present embodiment constitutes a speedometer, and is formed on the dial 5 by rotating the pointer 6A by a predetermined angle based on a sensor signal corresponding to a speed detected by a sensor (not shown). Point to a specific scale.

  The light source 2 of the present embodiment makes light (hereinafter referred to as “illumination light”) incident toward the lower end of the rotating shaft 4 and emits visible light having a predetermined wavelength (λ), for example, an LED (Light Emitting Diode (Light Emitting Diode). In the light source 2, the illumination light to be emitted has a uniform emission characteristic that does not depend on the direction of the phase angle. That is, the light source 2 of the present embodiment has a light quantity distribution characteristic that emits a substantially uniform quantity of light to the rotation shaft 4 over the entire 360 ° circumference in the horizontal plane (XY plane) direction. The light source 2 of the present embodiment is not particularly limited to this LED, but is preferably a small point light source with low power consumption.

  Although not shown in the figure, the motor case 3 includes a rotating shaft 4 in addition to the motor, the intermediate gear, and the output gear. The motor is for rotating the pointer 6A, and the pointer 6A is reliably rotated along the surface of the dial 5 by rotating the rotating shaft 4 by decelerating it through the intermediate gear and the output gear. And accurately point to the various information that you need.

  As described above, the rotating shaft 4 is rotated by the driving force transmitted from the motor, and has a substantially cylindrical shape made of a translucent material. The rotating shaft 4 is inserted in a state in which the upper end portion, which is the tip portion, is fitted in a cylindrical hole 64 described later of the pointer shaft 61 of the pointer 6A. Further, when the rotary shaft 4 is fitted into the cylindrical hole 64 of the pointer shaft 61, the pointer 6 </ b> A rotates about the axis of the rotary shaft 4. The rotating shaft 4 is installed on the back surface side of the dial plate 5, that is, on the lower surface side in FIG.

  Further, as shown in FIG. 1, the rotating shaft 4 is rotatably supported at a lower bearing 3A provided at the motor case 3 at a lower end portion which is a base end portion, and an upper end portion which is a distal end portion is a motor. The upper bearing 3B provided in the case 3 is rotatably supported. On the other hand, the light source 2 faces the lower end surface of the rotating shaft 4.

  As described above, the lower end surface of the rotating shaft 4 is provided so as to be positioned immediately above the light source 2, and when the illumination light from the light source 2 is incident, the illumination light is guided inside the rotating shaft 4 and the upper end portion. Propagate to. For this reason, the rotating shaft 4 is configured such that most of the above-described illumination light travels to the upper end portion while being totally reflected at the interface portion between the inside and the outside (air) on the outer peripheral surface. That is, in the present embodiment, in order to efficiently generate the total reflection phenomenon at the interface portion between the outer peripheral surface and the outside of the rotating shaft 4, the incident angle with respect to the outer peripheral surface is the natural wavelength of the illumination light. It is configured to be incident in a direction that always exceeds a corresponding predetermined critical angle. In this embodiment, the lower end surface of the rotating shaft 4 is formed in a circular arc shape from the center portion toward the peripheral portion.

  The dial plate 5 has a pointer shaft 61 of a pointer 6A, which will be described later, passed through a shaft hole 51 opened to a minimum size in a rotatable state.

  The pointer 6A is integrated with the rotary shaft 4 and rotates along the surface of the dial plate 5 with a base portion 62, which will be described later, as the center of rotation, thereby indicating a number or scale provided on the dial plate 5. The pointer 6A of the present invention has a sharp outer shape and a thinness like a second hand of a watch. Further, the illumination light can be reliably propagated to the tip having a narrow full length, and light and innovative light emission illumination can be performed over the entire length. Moreover, the pointer 6A can give the viewer a modern and luxurious metallic tone impression even when the illumination light for the pointer is turned off, and can bring a sense of quality. Furthermore, since the pointer 6A has a narrow shape over the entire length, the cap 7 can be applied in a small size, and the meter device 10 having a good appearance and high design can be realized. Hereinafter, the structure of the pointer 6A will be described in detail.

  The pointer 6A is made of an appropriate transparent resin material (transparent portion T). The pointer 6 </ b> A is integrally connected to the rotary shaft 4, a pointer shaft 61 that is the center of the rotation shaft of the pointer 6 </ b> A, a base portion 62 that is disposed substantially immediately above the rotation shaft of the pointer shaft 61, and the base portion 62. And a main body 63 extending in the direction of leaving.

  Among these, the pointer shaft 61 is provided with a light incident portion that receives illumination light from the light source 2 at the base end. The light incident portion of the present embodiment is configured by a cylindrical hole 64 whose base end portion is opened in a substantially hollow cylindrical shape. The cylindrical hole 64 of the pointer shaft 61 is configured such that the upper end portion of the rotating shaft 4 is press-fitted to a predetermined depth. As shown in FIG. 3, the ceiling surface 64A constitutes a convex surface having a convex lens function protruding toward the lower opening, and the illumination light incident thereon is directed toward the reflecting surface 62A of the base 62 described later. Converge. In addition, on the outer peripheral surface of the pointer shaft 61, a light shielding portion S to be described later is formed on the outer surface excluding the light incident portion, and the pointer shaft 61 itself is formed by a transparent portion T having high transparency. .

  As shown in FIG. 3B, the base portion 62 reflects the illumination light incident from the light incident portion disposed almost immediately above the pointer shaft 61 and deflects it so as to travel toward the tip of the main body portion 63. A reflective surface 62A is provided. The base 62 has a light shielding portion S, which will be described later, formed on the outer peripheral surface, and the base 62 itself is formed by a transparent portion T having high transparency.

  The main body 63 extends in a long shape from the base 62 toward the tip where the illumination light deflected after being reflected by the reflecting surface 62 </ b> A travels, and is formed integrally with the base 62. The main body 63 is formed in a substantially thin and narrow shape over the entire extended length, and has a sharp and cut shape like a second hand of a watch. By having such a narrow width shape, the cap 7 that covers the base portion 62 can also be reduced in size, particularly narrow.

  As shown in FIG. 2C, the main body portion 63 of the present embodiment is formed in a cross-sectional shape in which the upper surface is somewhat expanded toward the upper (Z) direction visually recognized by the viewer. (Y / + Y) The light-shielding portion S is formed over the entire length and the entire length (X) of both sides and the lower surface. The light-shielding portion S of the present embodiment is formed as a metallic plating layer by performing plating treatment over the entire length and the entire length of the lower surface, which is the back and right side surfaces, and the back surface of the main body portion 63 as the transparent portion T.

  Further, in particular, the main body portion 63 of the present embodiment has only the central portion excluding both edge portions along the left and right side surfaces over the entire length (X) of the upper surface as shown in FIGS. 2 (B) and 2 (C). A light shielding portion S is formed. In this way, the main body 63 emits a linearly sharp light emission by exposing a pair of transparent portions T over the entire length (X) of both edge portions along the left and right side surfaces of the upper surface. Part L is formed.

  Further, the main body 63 is subjected to appropriate processing on the lower surface, for example, a lot of diffusion processing such as embossing with fine unevenness 63A (see FIGS. 2A and 4), thereby causing many reflections. I am trying to make it. In particular, as shown in FIGS. 2 (A), 2 (C), and 5, the unevenness processing of the present embodiment forms each unevenness 63 </ b> A in parallel with the YZ plane so that each unevenness 63 </ b> A is formed. Incident illumination light is scattered in the X direction orthogonal thereto, and is effectively propagated to the tip of the main body 63.

  In this way, in the main body 63, by forming the light shielding portion S on the upper surface and the unevenness 63A on the lower surface, as shown in FIG. 5, the illumination light propagating to the base portion 62 is reflected between both of them. It can propagate effectively to the tip. Therefore, even if the main body 63 is formed in a thin shape, that is, even if the amount of transmitted illumination light is reduced, it is possible to effectively propagate a sufficient amount of illumination light to the tip. That is, since the main body 63 having a narrow width can be formed in a thin shape, even if it is formed in a sharp and smart shape such as a second hand of a watch, it is possible to sufficiently illuminate and emit light up to the tip.

  In the present embodiment, the metallic light shielding portion S made of a non-translucent film is configured by electroless plating the plastic resin on the pointer 6A. In addition, as this light-shielding part S, you may comprise a metallic light-shielding part by comprising with the metal reflective film which formed aluminum or the silver film, for example besides this. Further, the light shielding portion may be formed by depositing a dielectric multilayer film having a reflection function close to 100% with respect to the intrinsic wavelength (λ) of the illumination light, or may be formed by various coatings or hot stamping.

  As described above, the pointer 6A of the present embodiment achieves uniform luminance by scattering most of the illumination light incident thereon from the rotation axis 4 by the projections and depressions 63A, and the illumination light has high brightness in the eyes of the viewer. You can avoid plugging directly in the state. Further, since the three surfaces excluding the upper surface are surrounded by the light-shielding portion S from these outer surfaces over the entire length of the main body portion 63, light does not leak in the middle of these three surfaces, and illumination light is formed on a part of the upper surface. The light can be emitted from only the light emitting portion L toward the upper viewer to efficiently emit light.

  The cap 7 is an appropriate light-shielding property in order to prevent the illumination light from the light source 2 guided in the rotating shaft 4 from passing through the pointer shaft 61 and the base 62 of the pointer 6A as it is and leaking upward. Formed of material. The cap 7 covers the center of rotation of the pointer 6A, that is, the base 62 in a state that covers the outer surface of the base 62 and at least the shaft hole 51 of the dial 5. This prevents the illumination light from being transmitted from the upper surface of the base 62 to the outside, and when the illumination light may leak from the shaft hole 51 of the dial plate 5 through which the pointer shaft 61 passes, this is the eye of the viewer. To prevent direct incidence.

Next, the effect | action of the meter apparatus 10 which concerns on this embodiment is demonstrated, referring drawings.
As for the description of the meter device 10 here, the operation will be described by taking a speedometer as an example of each meter, but it is not particularly limited to this, and other analog type meter devices, etc. The same applies to the case of.

  When a vehicle equipped with the meter device 10 starts to move, a motor provided in the motor case 3 starts rotational driving based on a sensor signal detected by a speed sensor (not shown) and output according to the current speed. As a result, the pointer 6A is rotated by a predetermined angle according to the speed, and a specific scale or number formed on the dial 5 is indicated.

  That is, the rotating shaft 4 rotates at an angular velocity that matches the speed by a driving force from a motor (not shown). As a result, the pointer 6A is rotated through the pointer shaft 61 integrally fitted to the upper end portion of the rotary shaft 4, and a specific scale or number on the dial plate 5 is indicated at the tip of the pointer 6A. As a result, the current speed can be notified to the driver or the like by analog display.

  In the meter device 10 that performs such speed display, simultaneously with the speed display by the pointer 6A, the illumination light emitted from the light source 2 causes total reflection at the interface between the outer peripheral surface and the outer peripheral surface inside the rotary shaft 4. The propagation phenomenon that progresses upward is repeated. When this illumination light reaches the upper end portion of the rotary shaft 4, it is guided by the pointer shaft 61, and most of the illumination light travels from the ceiling surface 64A to the reflecting surface 62A immediately above it.

  And this illumination light is internally reflected by the slope which is the reflective surface 62A. As a result, the illumination light whose traveling light path is deflected by approximately 90 degrees inside the base portion 62 follows an optical path in which most of the illumination light travels toward the main body portion 63. Then, while exclusively reflecting between the light-shielding part S on the upper surface of the main body 63 and the unevenness 63A on the lower surface, the light travels toward the tip and is incident on the unevenness 63A on the lower surface to be scattered, thereby suppressing the luminance. To emit light.

  Therefore, according to the present embodiment, a driver who visually recognizes the pointer 6A does not need to insert illumination light with high brightness and strong stimulation into the eyes, and fatigue to the eyes is suppressed. In addition, at the same time, it is possible to perform sharp and innovative light-emitting illumination using the light-emitting portion L that forms a narrow pair over the entire length as a window.

  The main body 63 is provided with a large number of fine irregularities 63A (see FIG. 2A and FIG. 4) parallel to the YZ plane, so that a large number of scattering occurs. Illumination light incident on each unevenness 63A can be scattered in the X direction orthogonal thereto. As a result, even if the main body 63 is thin, a sufficient amount of illumination light can be effectively propagated to the tip of the main body 63.

  As described above, the pointer 6A has a sharp thinness and thinness as the second hand of the watch 63, so that the illumination light can be reliably transmitted to the tip of the thin and thin main body 63. Therefore, it is possible to perform sharp and innovative light-emitting illumination over the entire length. Moreover, since the pointer 6A is provided with a light-shielding portion S plated with a metallic tone in a line shape on the upper surface, when the illumination light for the pointer is turned off, the metallic 6 It is possible to obtain a sharp and high-quality appearance.

(Second Embodiment)
Next, a second embodiment according to the present invention will be described in detail with reference to FIG. In the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals to avoid redundant description.

  FIG. 6 shows a pointer 6B of a meter device to which the pointer illumination structure of the second embodiment is applied. The pointer 6B is different from the pointer 6A of the first embodiment in that the light shielding portion S formed on the upper surface of the main body 63 is formed along both side edges instead of the central portion along the full length direction. is there. Therefore, the light emitting portion L is formed over the entire length of the central portion of the upper surface of the main body 63, and a novel light emitting illumination that is sharp and sharp can be performed like the pointer 6A of the first embodiment.

  In addition, since the pointer 6B is provided with the light-shielding portions S on both side edges along the entire length of the upper surface of the main body 63 as described above, it is sharp and modern with respect to the pointer 6B when the illumination light is turned off. A luxurious metallic impression can be given, and a high-class feeling can be brought at the same time.

(Third embodiment)
Next, a third embodiment according to the present invention will be described in detail with reference to FIG. In the present embodiment, the same parts as those in the first and second embodiments are denoted by the same reference numerals to avoid redundant description.

  FIG. 7 shows a pointer 6C of a meter device to which the illumination structure of the pointer of the third embodiment is applied. The pointer 6C is different from the pointer 6A of the first embodiment and the pointer 6B of the second embodiment in that the light shielding portion S is not formed on the upper surface of the main body 63. That is, the pointer 6 </ b> C constitutes the light emitting portion L by exposing all the transparent portions T along the entire length direction of the upper surface of the main body portion 63. Thereby, compared with the pointer 6A of the first embodiment and the pointer 6B of the second embodiment, it is slightly less sharp, but a clear rod-like light emitting operation can be obtained over the entire length of the main body 63, and is novel. Luminous illumination can be performed.

  Further, even with the pointer 6C, when the illumination light is turned off, the light-shielding portions S provided along the entire length of both side surfaces of the main body 63 can be visually recognized from the outside. The impression can be given, and a high-class feeling can also be brought at the same time.

  The present invention is not limited to the embodiment described above, and can be implemented in various forms without departing from the gist of the present invention.

  In addition, the illumination structure of the meter device of the present embodiment constitutes a speedometer, but is not limited to this, and can be applied to various instruments such as a fuel gauge section, a tachometer section, and a water temperature gauge. .
