Description

  The present invention relates to a pointer instrument for a vehicle configured to indicate a physical state of a vehicle, for example, a vehicle speed by a pointer.

  For example, a speedometer (vehicle pointer instrument) indicating a vehicle speed includes a scale plate provided with a scale and a display unit including a vehicle speed (numerical value) corresponding to the scale, and a pointer disposed on the scale plate so as to be rotatable. And the vehicle speed is indicated by the pointer.

  This type of pointer generally has a single needle shape, and the scale and numerical value are indicated by the tip of the needle.

  By the way, for example, when traveling at a constant speed in consideration of fuel consumption and the environment, whether or not the tip indicates the desired scale with respect to the fine scale printed along the outer periphery of the scale board. It is necessary to perform visual recognition work continuously. However, since the scale is fine and the tip is generally thin, there is a problem that the visibility is low and labor is required for the visual recognition work.

  Conventionally, for example, Patent Document 1 discloses a technique for improving the visibility. This is because the ring-shaped condensing resin member is arranged on the outer peripheral side of the scale displayed on the scale board, the LED pointer is arranged on the back side of the scale board, and the portion indicated by the meter pointer is displayed. It is configured to emit light.

  Patent Document 2 also includes an outer pointer having an opening formed by two legs, an inner pointer disposed between the two legs, and a light source. An illuminated pointer is disclosed that points to the two scales independently.

  However, although the structure of Patent Document 1 can improve the visibility, it is necessary to separately provide a light-collecting resin and an LED pointer, and there is a problem that the structure becomes complicated and the cost is increased. .

  Moreover, in the structure of the said patent document 2, since the scale is pointed by the front-end | tip part of the outer side and the inner side, the problem that an effort is required for the said visual recognition work cannot be solved.

  The present invention has been made in view of the above-described conventional situation, and it is an object of the present invention to provide a vehicular pointer instrument with a simple structure and capable of easily recognizing numerical values and scales.

The invention of claim 1 includes a scale plate provided with a scale and a display unit having a numerical value corresponding to the scale, and a pointer disposed on the scale plate so as to be rotatable. In the vehicular pointer instrument configured to be pointed to by the pointer, the pointer includes a tip indicating unit indicating a numerical value indicating a physical state of the vehicle at that time, and a scale corresponding to the indicated numerical value. It is characterized by having a frame portion surrounding the whole so as to fit inside .

  According to a second aspect of the present invention, in the vehicular pointer instrument according to the first aspect, the pointer is erected on a main body portion whose cross-sectional area gradually decreases toward the tip indicating portion, and an upper surface of the main body portion. The frame portion is constituted by a standing portion, and the main body is provided with a light source for irradiating light.

  According to a third aspect of the present invention, in the vehicular pointer instrument according to the second aspect, a paint is applied to the standing portion.

  According to the invention of claim 1, the numerical value corresponding to the scale is indicated by the tip indicating portion of the pointer, and the scale corresponding to the numerical value is surrounded by the frame portion provided on the pointer, The visual recognition work can be performed only by confirming whether or not the scale is within the range, and the visibility can be improved with a simple structure.

  According to the invention of claim 2, since the pointer is composed of a main body portion whose cross-sectional area gradually decreases toward the tip indicating portion, and a standing portion provided on the upper surface of the main body portion, When used at night, the light from the light source can be reliably supplied to the tip, and sufficient visibility can be ensured even at night.

  That is, as in the present invention, when the pointer is relatively large, it may be difficult to supply light from the light source to the distal end of the pointer. Since the size is gradually reduced toward, the fear can be avoided.

  Moreover, since the tip becomes lighter, the rotation balance of the pointer becomes good, and a stable rotation operation can be obtained.

  According to invention of Claim 3, since the coating material was apply | coated to the upper surface of the said standing part, the blurring by the refraction of light can be suppressed, and the visibility at night can further be improved from this point.

It is a sectional side view (III-III line sectional view of Drawing 1) showing the indicator arrangement state of the speedometer. It is a perspective view of the pointer. FIG. 5 is a cross-sectional front view of the pointer (a cross-sectional view taken along line V-V in FIG. 4). FIG. 5 is a cross-sectional front view of the pointer (a cross-sectional view taken along line VI-VI in FIG. 4). It is a side view of the pointer.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  1 to 7 are views for explaining a speedometer (vehicle pointer instrument) according to a first embodiment of the present invention.

  In the figure, reference numeral 1 denotes an automobile speedometer, and the speedometer 1 is disposed in a meter cluster (not shown) provided on an instrument panel (not shown) provided in the passenger compartment. ing.

  The speedometer 1 includes a scale 5 provided with a scale 3 disposed at a predetermined angular interval on a circular arc and a display unit 4 including a speed (numerical value) 2 printed corresponding to the scale 3. The base plate 6 is provided on the back side of the scale plate 5 and the pointer 7 is supported by the base plate 6 so as to be pivotable and can rotate on the scale plate 5 in the circumferential direction.

  A resin cap 8 is fixed to the rear portion of the pointer 7. The cap 8 includes two parts, a substantially cylindrical cover portion 8a having an upper wall 8c and a side wall 8b, and a bottom wall portion 8d. The cover portion 8a is coupled to the bottom wall portion 8d by legs 8g, 8g extending downward from the upper wall 8c.

  A pointer shaft 8h is integrally formed at the center of the bottom surface of the bottom wall portion 8d. The pointer shaft 8h extends toward the base 6 through a shaft hole 5a formed in the center portion of the dial plate 5, The step motor 6 a disposed on the base 6 is coupled.

  A plurality of LED light sources 6b are mounted on the base 6 so as to be adjacent to the step motor 6a.

  The pointer 7 passes through the cover portion 8a through notches 8e and 8e formed at the front and rear portions of the side wall 8b of the cover portion 8a, and the rear end portion 7d protrudes rearward. In addition, flanges 9b and 9b extending left and right are integrally formed on the inner portion of the pointer 7 of the pointer 7 and the flanges 9b and 9b are formed on the bottom wall by the legs 8g and 8b. It is fastened together with the portion 8d. Thereby, the pointer 7 is rotated together with the cap 8 by the rotation of the step motor 6a. A metal weight 8f for improving the rotational balance is disposed in the cap 8 so as to be located behind the pointer shaft 8h. In addition, since the rear end portion 7d of the pointer 7 protrudes rearward, the rotation balance of the pointer 7 is good.

  The pointer 7 is, for example, a bar made of transparent acrylic resin, and includes a main body portion 9 and a standing portion 10 that is erected on the upper surface of the main body portion 9. The main body 9 has a rectangular cross section, and its thickness gradually decreases toward the tip, so that its cross-sectional area gradually decreases toward the tip. The standing portion 10 is erected in a rib shape having the same height over the entire periphery of the upper surface of the main body portion 9.

  And the front-end part of the said main-body part 9 and the standing part 10 becomes the front-end | tip instruction | indication part 7a which points to the said numerical value 2, and the scale 3 corresponding to the said numerical value 2 is shown from the circumferential direction and the numerical value 2 side. It is a surrounding frame portion 7b.

  On the lower surface of the main body 9, a light condensing part 9a is formed on the front side of the pointer shaft 8h so as to protrude downward. The condensing part 9a is exposed downward from the opening 8i formed in the bottom wall part 8d of the cap 8 so as to face the LED light source 6b.

  A coating film 10 a is formed on the upper surface of the standing part 10 by coating. The coating film 10 a is for preventing light supplied from the main body portion 9 to the standing portion 10 from being refracted by the standing portion 10.

  In the speedometer 1 according to the first embodiment, when the vehicle width lamp is turned on, the light from the LED light source 6b is applied to the light condensing unit 9a, reflected by the reflecting unit 9c, and passed through the pointer 7 inside. It is transmitted to the instruction section 7a side and the rear end section 7d side.

  When the vehicle speed is 60 km / h, for example, the tip indicating portion 7a indicates a numerical value 2 'indicated as 60, and at the same time, the frame portion 7b indicates a scale 3' corresponding to the indicated numerical value 2 '. It will be surrounded.

  According to the first embodiment, the tip indicating portion 7a of the pointer 7 indicates the numerical value 2 'corresponding to the vehicle speed at that time, and the frame portion 7b provided on the pointer 7 indicates the scale 3' corresponding to the numerical value 2 '. Since it surrounds, visibility becomes favorable and the visual recognition operation | work of a vehicle speed is easy.

  In particular, for example, when it is desired to run at a constant speed of 60 km / h, it is necessary to always visually confirm that the pointer points to a numerical value and scale indicating 60 km / h. Since it is only necessary to visually check whether or not the scale 3 'corresponding to 60 Km / h is located in the portion 7b, the visibility can be improved with a simple structure, and the above-described visual operation can be easily performed. It is possible to reduce the labor required for visual recognition work in continuous constant speed running.

  Here, when the pointer 7 is relatively large as in the present embodiment, it may be difficult to supply light from the light source to the tip of the pointer. However, in this embodiment, the pointer 7 is composed of the main body portion 9 whose sectional area gradually decreases toward the tip portion and the standing portion 10 provided on the upper surface of the main body portion 9, so that the LED light source 6b. Can be reliably supplied to the tip indicating portion 7a, and sufficient visibility can be ensured even at night.

  Further, since the cross-sectional area of the main body 9 is reduced toward the tip, the tip 9 is lighter, the rotation balance is good, the rotation operation of the pointer 7 is stabilized, and the speed display accuracy is improved.

  Further, in this embodiment, since the coating film 10a formed by applying a paint on the upper surface of the standing portion 10 is formed, blurring due to light being refracted by the standing portion 10 can be suppressed, and at night Visibility can be further improved.

  In the first embodiment, the scale 3 and the speed 2 are arranged on an arc. However, the scale and speed of the present invention may be arranged on an inverted U shape or a gate shape, for example. Moreover, although the case where the frame part 7b was comprised with the main-body part 9 and the standing part 10a formed over the all the periphery of this was demonstrated, the frame part of this invention is the scale 3 in front of the circumferential direction. , It may be formed so as to be sandwiched later.

  In the first embodiment, the case where light is emitted from the LED light source when the vehicle width lamp is turned on has been described. However, the light may be emitted when the accessory power source is turned on.

  Furthermore, in the first embodiment, the case of the speedometer has been described, but the present invention can be applied to general vehicle indicator instruments such as an engine tachometer, a hydraulic gauge, and a fuel gauge.
