TWI289115B - A dash-board gauge - Google Patents

Abstract

This invention relates to a dash-board gauge, which includes a light-received part that has a graduation ring, and a light-projecting part that projects a light beam onto the graduation ring. The direction of the light-projecting part can be changed, so that it can be used as virtual image needle and as a substitute for the physical needle. The virtual image needle is invisible in the area between the light-projected part and light-received part so that it will not block the LED displaying area.

Description

1289115 V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a meter for an automatic two-wheeled vehicle, and more particularly to a design for converting a physical pointer into a virtual pointer, and projecting light to an engraved area (light receiving portion) In order to provide the recognition effect, the pointer light source is invisible to the virtualized pointer between the engraved areas, and does not affect the metering area of the liquid crystal display (LCD). [Prior Art]

According to the car, the locomotive and the locomotive are one of the vehicles commonly used by modern people. These vehicles are equipped with meters to display information about various driving (such as speed, fuel quantity, mileage, engine speed, temperature, etc.), so driving The driving of people is very important. Please refer to the first figure and the second figure, which discloses that there are two kinds of pointer instruments for conventional vehicles, and the meter mainly uses the indicators 80, 8 1 and 8 3, 8 4 to display information such as speed and oil quantity, and The mileage is displayed by mechanical rollers 8 2 , 8 5 . The pointers 80, 8 1 , 8 3 , and 8 4 are controlled to rotate by means of a motor, a movement, or a coil, so as to indicate the area of the meter with a physical pointer, and display information such as speed and oil amount by analogy.

Please refer to the third figure, which discloses another conventional vehicle instrument that uses both the pointer 86 and the liquid crystal display (LCD) 8 7 to display information. Please refer to the fourth figure, which discloses another conventional vehicle instrument for an all-digital display instrument that uses liquid crystal display 8 8 to display information. However, due to the poor visual recognition of such full-digital display instruments, most of them are still in the form of liquid crystal displays and pointers.

5 is placed in a meter, but in the table, it is necessary to avoid the separation of the finger up and down or left and right, so that the liquid crystal display and the pointer f are set in a needle identification area to set the liquid crystal display, generally (As shown in the third figure), the design is to be achieved. For example, the setting of the indicator and the pointer needs to occupy a large area. See the fifth figure, which discloses another instrument for the conventional vehicle, which also uses the pointer 8 at the same time. I and the liquid crystal display 9 显示 to display the information 'Because the pointer 8 9 has a transparent part made of transparent material 9 1 port, this can be set in the pointer 8 9 identification area LCD 9 0 ' 4 drivers still pass The transparent portion 91 of the pointer 8 9 sees the information displayed by the liquid crystal display 9 ,. Although the design can see the information displayed by the liquid crystal display 9 through the transparent 4 9 1 of the pointer 8 9 , the shaking pointer 8 9 Located in front of the LCD monitor 9 ,, it will inevitably affect the driver's identification of the LCD display 90 information, still cause inconvenience in use. It is obvious from the above that the above-mentioned various instruments are actually inconvenient and lacking in actual use, and can be improved. On the other hand, the inventor of the present invention is aware of the improvement of the above-mentioned defects, and has devoted himself to researching the application of the sub-association theory, and finally proposed a present invention which is rational in design and effective in improving the above-mentioned deficiency. SUMMARY OF THE INVENTION The main object of the present invention is to provide a meter that converts a solid 1-pin transition into a virtualized pointer, projecting light into the engraved area to provide an identification effect, and between the source and the engraved area.
