Embodiment 1

[0021] see figure 1 , the present invention discloses a pointerless meter device, comprising a meter panel 1 with a scale, and a motor 2 provided with an indicating shaft 3; the indicating shaft 3 rotates correspondingly according to the indicated data; the meter device also It includes an indicating unit, which includes a light source 4 and a lens 5, the light source 5 is fixed on the indicator shaft 3, and the lens 5 is arranged between the light source 4 and the scale of the instrument panel 1; the beam of light source 4 The emitted light beam is collected by the lens 5 and directed to the corresponding scale of the instrument panel 1 .

[0022] The lens 5 can be a single lens, but in view of the poor light-gathering effect of a single lens, a multi-angle lens is selected in this embodiment. One of the lenses with different angles is set in the center, and the rest are distributed around at appropriate angles. The focal points of each lens should coincide at one point. Adj...

Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that in this embodiment, the watch device can also be watches such as watches, pocket watches, and clocks.

Embodiment 3

[0033] The difference between this embodiment and the above-mentioned embodiment is that, according to the difference of the scale, at least two panels of different colors are set as reflection areas on the dial. For example, set a speed upper safety limit, when the driving speed is within the safe value, the light source emission will be displayed in green on the panel of the instrument panel 1; when the driving speed is outside the safe value, the color of the scale panel will change, making When the light source is emitted to the panel of the instrument panel 1, it is displayed in red, indicating that the speed of the vehicle is too high and dangerous.

Abstract

The invention discloses a meter device without an indicating hand and comprises a dial plate with scales and a motor with an indicating shaft; the indicating shaft rotates correspondingly according to indicated data; the meter device further comprises an indicating unit, which comprises a light source and a lens, the light source is fixed on the indicating shaft, the lens is arranged between the light source and the scales of the dial plate, and the light beam source emits light beams that point to the corresponding scales of the dial plate after being gathered by the lens. The indicating unit of the meter device of the invention utilizes light ray to replace the indicating hand for scale indication, and the light beams are directly irradiated on the scales, thus having large contrast between indication stopping and starting, as well as good visual effects.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics, and relates to a watch device, in particular to a pointerless meter device; in addition, the invention also relates to an indicating unit of the meter device. Background technique [0002] Based on the trend of instrument digitalization, the degree of automotive electronics is getting higher and higher, requiring high technology, high precision, and high sensitivity, and pursuing a simple and beautiful appearance of the instrument. [0003] Most of the existing instruments or watches indicate the speed, time and other data of the vehicle by means of mechanical pointers, and the magnetic steel is driven to rotate through the flexible shaft, and an eddy current is formed in the induction cover to generate a magnetic field, which is deflected by the action of the magnetic steel magnetic field, making it The connected pointer also rotates accordingly to indicate the vehicle speed or ro...
