Detailed Description

The embodiment of the utility model provides a panel board based on optical reflection adjusts luminance in a poor light, as shown in fig. 1-5, including panel board 1. The back welding of 1 back of panel board has

pipeline

2, and 1 one end welding of panel board has receiver tube 3 is kept away from to pipeline 2, and the 3 tops of receiver tube can contact with external light, and pipeline 2 and receiver tube 3 are with leading-in panel board 1 of light for 1 inside light of panel board brightens.

As shown in fig. 4, a lens 4 is fixedly mounted on the top of the receiving tube 3, and a transparent film 5 is embedded on the inner wall of the receiving tube 3. A spring 7 is arranged between the lens 4 and the transparent film 5, and the top of the spring 7 is fixedly adhered to the center of the lens. The motor 6 is fixedly arranged on the left side and the right side of the receiving pipe 3, and a steel wire 61 is welded at the transmission end of the motor 6. The steel wire 61 penetrates through the receiving pipe 3 and is fixedly bonded with the surface of the transparent film 5. Singlechip 8 is all fixedly installed to both sides around the receiver tube 3, and photosensitive sensor 9 is connected to the electric connection on singlechip 8. The inner wall of the receiving tube 3 is coated with a reflective layer.

As shown in fig. 4 and 5, the pipeline 2 is a straight line segment, a first reflecting mirror 21 and a plurality of second reflecting mirrors 22 are embedded in the pipeline 2, and the first reflecting mirror 21 is located at the joint of the pipeline 2 and the receiving pipe 3. The second plurality of reflectors 22 are equidistantly arranged on the upper inner wall and the lower inner wall of the pipeline 2, and the first reflectors 21 and the second reflectors 22 are used for guiding light rays into the instrument panel 1.

During daytime, sunlight irradiates on the receiving tube 3, the photosensitive sensor 9 converts light intensity into an electric signal, and the single chip microcomputer 8 controls the motor 6 according to the received signal. When light is weaker, the single chip microcomputer 8 controls the motor 6 to rotate, the motor 6 drives the shaft to wind the steel wire 61, the steel wire 61 pulls the transparent film 5 upwards, the transparent film 5 is enabled to be sunken upwards, and the spring 7 is extruded at the moment. The transparent film 5 and the lens 4 constitute a concave lens, thereby converging light rays. The converged light irradiates the inner wall of the receiving tube 3, is reflected on the first reflecting mirror 21 and is reflected to the second reflecting mirror 22, so that the light is guided into the instrument panel 1. Because the light rays irradiated on the first reflector 21 by the convergence effect are more, the light rays introduced into the instrument panel 1 are more, and the brightness is high.

When light is too violent, the motor 6 does not work, the steel wire 6 does not pull the transparent film 5, the spring 7 slowly resets the original state, the spring 7 enables the transparent film 5 to protrude downwards, and the transparent film 5 and the lens 4 form the convex lens. The light rays are scattered when the light rays enter the receiving tube 3, the light rays reflected on the reflector are few, and the light rays led into the instrument panel 1 are few, so that the brightness is weakened.

The single-chip microcomputer 8 and the photosensitive sensor 9 are conventional technical means, and the scheme does not make innovation on the single-chip microcomputer and the photosensitive sensor, so that the specific model, the specific structure, the circuit arrangement and the like are the same as those in the prior art and are not described in detail.

The instrument panel 1 consists of a shell 11, a dial 12, a pointer 13, a plurality of glass blocks 15 and a ring 17, wherein the back of the shell 11 is welded with the pipeline 2, and the ring 17 is welded with the bottom of the inner wall of the shell 11. The dial 12 is welded on top of the ring 17 and the pointer 13 is pivoted in the centre of the dial 12. The plurality of glass blocks 15 are mounted on the dial 12 at equal angles around the axis, the inner side of the ring 17 is funnel-shaped, and the inner side of the ring 17 is bonded with a reflection film 171. Since the present embodiment does not innovate the driving mechanism for driving the indicating needle 13, the driving mechanism for driving the indicating needle 13 is the same as the prior art, and is not described in detail and not shown in the drawings.

In operation, light is guided into the instrument panel 1 through the duct 2 and the receiver tube 3, and passes through the reflective film 171 on the inner side of the ring 17 to photograph the dial 12. The dial 12 is opaque and the glass block 15 is transparent. The light passes through the glass block 15, so that the glass block 15 becomes bright as a whole. The glass block 15 is used for marking a scale so as to facilitate reading of the numerical values in the instrument panel 1.

Compared with the prior art, the instrument panel for adjusting the backlight brightness based on optical reflection guides external light into the instrument panel 1 through the cooperation of the reflector, the receiving tube 3 and the pipeline 2 based on the optical reflection principle. Through the mutual cooperation of ring 17, dial plate 12, glass piece 15 for light sees through glass piece 15 and produces the bright area, reaches the effect of LED lamp backlight. And the light quantity emitted to the reflector is changed by matching the photosensitive sensor 9, the singlechip 8, the motor 6, the steel wire 61, the lens 4, the spring 7 and the transparent film 5, so that the effect of changing the brightness is achieved. The LED lamp is replaced to work in the daytime, so that the effects of saving energy consumption and protecting the environment are realized.

The inside cavity of ring 17 has seted up the storage chamber, and the storage chamber is used for accomodating other electronic component. An LED lamp strip 14 is inlaid at the top of the pointer 13, an LED lamp ring 16 is fixedly mounted on the back of the dial 12, and the LED lamp ring 16 and the dial 12 are arranged in a concentric circle mode. As can be seen from fig. 3, the LED light ring 16 does not completely cover the glass block 16. The light can pass through the glass block 15. The LED light bar 14 and the LED light ring 16 are used for night illumination.

The working principle is as follows: during the use, in pipeline 2, the receiver tube 3 leading-in panel board 1 of light process, sunshine shines on receiver tube 3, and photosensitive sensor 9 converts the signal of telecommunication into according to light intensity, and singlechip 8 is according to received signal control motor 6. When light is weaker, the single chip microcomputer 8 controls the motor 6 to rotate, the motor 6 drives the shaft to wind the steel wire 61, the steel wire 61 pulls the transparent film 5 upwards, the transparent film 5 is enabled to be sunken upwards, and the spring 7 is extruded at the moment. The transparent film 5 and the lens 4 constitute a concave lens, thereby converging light rays. The converged light irradiates the inner wall of the receiving tube 3, is reflected on the first reflecting mirror 21 and is reflected to the second reflecting mirror 22, so that the light is guided into the instrument panel 1. Because the light rays irradiated on the first reflector 21 by the convergence effect are more, the light rays introduced into the instrument panel 1 are more, and the brightness is high.

To sum up, the instrument panel for adjusting the backlight brightness based on optical reflection guides the external light into the instrument panel 1 through the cooperation of the reflector, the receiving tube 3 and the pipeline 2 based on the optical reflection principle. Through the mutual cooperation of ring 17, dial plate 12, glass piece 15 for light sees through glass piece 15 and produces the bright area, reaches the effect of LED lamp backlight. And the light quantity emitted to the reflector is changed by matching the photosensitive sensor 9, the singlechip 8, the motor 6, the steel wire 61, the lens 4, the spring 7 and the transparent film 5, so that the effect of changing the brightness is achieved. The LED lamp is replaced to work in the daytime, so that the effects of saving energy consumption and protecting the environment are realized.
