Embodiment 1
[0017] Such as figure 1 As shown, the indicating method of the automobile meter of the present invention includes a process of using the pointer 2 to indicate the state of the meter, wherein, in the process of using the pointer 2 to indicate the state of the meter, light-emitting diodes are used to illuminate the pointer 2, and change the light-emitting color of the light-emitting diode according to the offset of the pointer 2, and use the color change of the pointer to indicate the status of the meter.
[0018] The present invention also provides an indicating structure for realizing the above method. The indicating structure of the automobile instrument includes an instrument seat (not shown in the figure), a dial 1 and a pointer 2, and the dial 1 is arranged in the instrument seat , the pointer 2 is composed of a light guide body, the pointer 2 is arranged in front of the dial 1, and the root of the pointer 2 is provided with a driving shaft (not shown in the figure), and t...

The invention discloses an indicating method of an automobile instrument. A pointer is illuminated through light-emitting diodes, light-emitting colors of the light-emitting diodes are changed according to the deviation of the pointer, and the condition of the instrument is indicated according to the color change of the pointer. According to the method, an indicating structure comprises a dial plate and the pointer, the pointer is composed of a light conducting body, the pointer is arranged in front of the dial plate, a driving shaft is arranged on the root portion of the pointer, the driving shaft is connected with a driving mechanism, a light entrance port is formed in the root portion of the pointer, at least one three-color light-emitting diode or more than three single-color light-emitting diodes are arranged on the dial plate, light-emitting color differences exist among the three single-color light-emitting diodes, the three-color light-emitting diode or the single-color light-emitting diodes are adjacent to the light entrance port, and the three-color light-emitting diode or the single-color light-emitting diodes are connected with an instrument control circuit. Deviation is output to the pointer by the instrument control circuit according to input data. The light-emitting diodes are lighted according to the deviation degree of the pointer, the indicating portion of the pointer is illuminated, and a driver can be markedly and directly reminded of a current condition.
Description
Technical field: [0001] The invention relates to the field of electricity, in particular to an automobile instrument, in particular to an indicating method and an indicating structure of an automobile instrument. Background technique: [0002] Automobile instruments, such as speedometer, tachometer and oil pressure gauge, etc., use the pointer to indicate the current running status of the car, and use monochromatic light-emitting diodes to illuminate the pointer to help the driver identify the position of the pointer when the light is dark, so that the driver can understand the position of the pointer The current situation of the car has an intuitive understanding, which plays an important role in reducing the occurrence of traffic accidents. Because the pointer is thin, the driver needs to pay more attention to the position of the pointer when understanding the indication of the instrument, which is not conducive to driving safety. Invention content: [0003] The object ...
