Description

Pointer instrument and combination instrument

Technical Field

The utility model relates to the field of automobiles, concretely relates to pointer instrument and combination meter.

Background

Usually, the dial of the pointer instrument is printed with white ink on the side facing the driver, so that the scale lines and scale values on the dial of the pointer instrument can be seen even when the pointer instrument is not powered, i.e., the LED is not lit.

The light that LED sent passes through the leaded light support, if direct irradiation dial plate back, because LED is the pointolite, the scale mark and the scale value luminance of demonstration can be inhomogeneous. Therefore, the gray grid is printed on the back of the scale lines and scale values by silk screen printing, and the brightness of the displayed scale lines and scale values is ensured to be uniform by light scattering.

If a pointer instrument is needed, the scale marks and scale values on the dial plate are not displayed when the pointer instrument is not powered, namely, the full black effect is realized. Therefore, the white scale and the scale value cannot be printed on the side facing the driver, if the gray grid is printed to ensure that the brightness of the scale lines and the scale value is uniform, the grid can be transmitted when the LED is lightened, and the display effect of the scale lines and the scale value is influenced.

The utility model provides a pointer instrument, including pointer, dial plate, leaded light support and PCB board, be provided with LED on the PCB board, only print can non-light tight printing ink in the display area on dial plate surface, be provided with the one or more light guide plate that covers display area between dial plate and the leaded light support.

Further, the display area at least comprises scale marks and scale values.

Further, the light guide plate is annular or partly annular, corresponds to the distribution of scale mark and scale value on the dial plate.

Furthermore, the edge of the light guide plate is provided with a buckle for clamping the light guide plate on the light guide bracket.

Further, the light guide plate is attached to the inside surface of the dial at a position corresponding to the display area on the dial.

Further, the ink capable of transmitting light is a transparent ink or a translucent ink.

Further, the ink capable of transmitting light is transparent black.

Further, the light guide plate is formed by injection molding.

The utility model also provides a combination meter, including above-mentioned pointer instrument.

Furthermore, the number of the pointer meters is at least two, and a display screen is arranged between the pointer meters.

Compared with the prior art, the utility model provides a pointer instrument and combination meter has following beneficial effect: the display area on the inner side surface of the dial plate is only printed with black ink capable of transmitting light, and the light guide plate is used for ensuring uniform display, so that the full black effect of the instrument can be realized, and the display effect cannot be influenced by grids.

FIG. 1 is a schematic diagram of a cluster tool according to an embodiment of the present invention when powered;

FIG. 2 is a schematic view of the combination meter of FIG. 1 when unpowered;

FIG. 3 is an exploded view of the combination meter shown in FIG. 1;

fig. 4 is a partial sectional view of the cluster shown in fig. 1.

Detailed Description

The utility model discloses a combination meter is shown in figure 1 when powering up, and this combination meter includes the pointer instrument, and the left side is speedometer 1, and the right side is speedometer 2, and upper portion is provided with display screen 3 between speedometer 1 and the speedometer 2, and the lower part is provided with two pointer instruments, and the left side is thermometer 4, and the right side is fuel gauge 5.

When the combination meter is not powered on, as shown in fig. 2, the pointer meter can only see the pointer, and cannot see the scale marks, scale values and the like.

The following description will be made by taking a tachometer 1 as an example.

As shown in fig. 3, the tachometer 1 includes a pointer 11 (not shown), a dial 12, a light guide holder 14, and a PCB 15 on which an LED151 is disposed. Here, the display screen 3 is not included for the sake of simplicity.

Here, it is to be noted that: the scale lines and scale values shown on the dial 12 in fig. 3 are drawn for illustrative purposes only, and the actual dial 12 is usually black, and the scale lines and scale values and their surroundings (printed with opaque black ink) are all black with no significant difference (as shown in fig. 2).

In the present embodiment, as shown in fig. 4, only transparent ink is printed on a display area, for example, a scale line, on the surface of the dial 12 to form an ink layer 121, and a light guide plate 13 is provided between the dial 12 and the light guide holder 14, so that the light guide plate 13 can cover the display area.

Ink layer 121 can be on the inside surface and/or the outside surface of dial 12.

The light emitted by the LED151 passes through the light guide holder 14, penetrates through the light guide plate 13, and irradiates the dial 12, and the light guide plate 13 can ensure that the scale marks and scale values on the dial 12 are displayed uniformly.

The ink capable of transmitting light is transparent ink or translucent ink, and in this example, the ink capable of transmitting light is transparent black. In other embodiments, multiple layers of transparent or translucent inks may be used, for example, transparent black and transparent gray may be used if desired to display, for example, dark gray.

Of course, in other embodiments, a plurality of light guide plates may be provided, and the combination of the plurality of light guide plates may cover the display area.

The display area at least comprises scale lines and scale values, such as scale value 3 in the tachometer of FIG. 1, and the display area may further comprise scale lines and scale values of FIG. 1

Restrictions and warnings of danger zones may also be included, for example, in FIG. 1, the warning zones between the tick marks corresponding to rotational speeds of 6500-7000RPM, 7000-8000RPM, may be printed with clear red ink.

Here, the display area is a sum of areas that can be displayed and seen by the driver when the tachometer is operated, and is composed of a plurality of independent small areas, and is usually a discontinuous area. The display area here does not include an area corresponding to an alarm symbol.

The light guide plate 13 is shaped to correspond to the display area on the dial, where corresponding means at least covering the display area, and the light guide plate 13 may be continuous for ease of manufacturing and assembly, as shown in fig. 3, in this embodiment.

Here, in other embodiments, the light guide plate may be discontinuous, for example, a through hole may be formed in the light guide plate or the light guide plate may include a plurality of light guide plates, as long as the light guide plate can cover the display region.

Since the scale lines and scale values on the dial of the pointer instrument are usually distributed in a ring shape or a partial ring shape, the light guide plate may be correspondingly distributed in a ring shape or a partial ring shape, and in this embodiment, the light guide plate 13 is a partial ring shape.

The edge of the light guide plate 13 is provided with a buckle 131 for being clamped on the light guide holder 14, for example, the buckle 131 is clamped on a clamping position 141 on the light guide holder 14, as shown in fig. 4. Each buckle all has corresponding screens.

The light guide plate 13 is formed by injection molding.

The light guide plate 13 is attached to the inside surface of the dial 12 at a position corresponding to the display area on the dial 12.

In the combined instrument in the embodiment, the speedometer 2, the water thermometer 4 and the fuel gauge 5 of other pointer instruments are similar in structure, the speedometer 2 is provided with English scale lines and scale values except metric scale lines and scale values arranged on the outer ring, and the inner ring is also provided with English scale lines and scale values, so that the light guide plate correspondingly covers a larger display area.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited thereto. Various changes and modifications can be made by one skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention is to be determined by the appended claims.
