Abstract

The utility model discloses a windshield capable of changing color. The windshield comprises a photosensitive sensor, an amplifier, a single chip microcomputer module, a temperature sensor, a current controller, a resistance heating module and a temperature sensing color changing layer. The single chip microcomputer module is respectively connected with the amplifier, the temperature sensor and the current controller. The photosensitive sensor is connected with the single chip microcomputer module through the amplifier. The current controller, the resistance heating module and the temperature sensing color changing layer are connected in sequence. Color changing can be carried out according the brightness of external light, the effect of sunglasses is achieved, safety of vehicle running during day time with strong light and at night is guaranteed, convenience and practicability are achieved, and the windshield is worth popularizing.

Description

A kind of Windshield of changeable colour

Technical field

The utility model belongs to automobile, particularly a kind of Windshield of changeable colour.

Background technology

At present, in daily life, people's trip all can be used automobile to ride instead of walk, the quantity of automobile is more and more, when extraneous light is crossed when strong, when especially the sun in summer height shines, extraneous light luminance is excessively strong, when people drive to travel, eyes can be subject to the stimulation of extraneous relation, cause tired out, have a dizzy spell, in addition, night is while driving a vehicle, when Lu Shangruo chance opposite driving vehicle is enabled headlight, can be dangerous, although last situation can be avoided during with sunglasses, but going out provisional capital need to be with cumbersome at every turn, night is while driving a vehicle, sunglasses just can not have been used, so need to a kind ofly can carry out according to light the Windshield of variable color.

The utility model content

The utility model, for the defect of background technology, has proposed a kind of Windshield of changeable colour, can carry out variable color according to the brightness of extraneous light, plays the effect of sunglasses, has guaranteed that daytime, light was crossed the safety strong and driving in night, convenient and practical, is worthy to be popularized.

In order to address the above problem, the technical solution of the utility model is as follows:

A kind of Windshield of changeable colour, comprise photosensor, amplifier, one-chip computer module, temperature sensor, current controller, resistance heat module and heat discoloration layer, wherein, one-chip computer module is connected with amplifier, temperature sensor and current controller respectively, photosensor is connected with one-chip computer module by amplifier, and current controller, resistance heat module, heat discoloration layer are connected successively;

The heat discoloration layer evenly is coated on windshield, photosensor is inputted one-chip computer module by the extraneous light luminance signal of sensing by amplifier, the simultaneous temperature sensor is by the temperature signal input one-chip computer module recorded, and one-chip computer module judges whether to current controller output control signal according to light luminance signal and the temperature signal of aforementioned reception; Described current controller, according to the control signal starting resistance heating module of one-chip computer module, makes the rear variable color of heat discoloration layer temperature rising.

As further prioritization scheme of the present utility model, the outside face of described heat discoloration layer is also with thin film.

The utility model adopts above technical scheme compared with prior art, has following technique effect:

The first, can regulate the color of Windshield according to extraneous light luminance, avoid light to cross the human discomfort of strong band to chaufeur, increase the safety of chaufeur;

The second, circuit is simple, sensitieness is high, making is simple, be worthy to be popularized.

The accompanying drawing explanation

Fig. 1 is circuit diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail:

A kind of Windshield of changeable colour, structure as shown in Figure 1, comprise photosensor, amplifier, one-chip computer module, temperature sensor, current controller, resistance heat module and heat discoloration layer, wherein, one-chip computer module is connected with amplifier, temperature sensor and current controller respectively, photosensor is connected with one-chip computer module by amplifier, and current controller, resistance heat module, heat discoloration layer are connected successively;

The heat discoloration layer is colourless when extraneous light luminance is less than the threshold value of one-chip computer module, during higher than the micro controller system threshold value, is black, and the outside face of heat discoloration layer is also with thin film.

There is predefined program one-chip computer module inside, when extraneous light luminance is crossed when strong, meeting starting current controller, the raise temperature of heat discoloration layer of resistance heat module, the one-chip computer module internal processes has predefined threshold value, when the light luminance signal is less than or equal to threshold value, the temperature-sensing color-changing material of heat discoloration layer inside is colourless, when the light luminance signal is greater than threshold value, temperature-sensing color-changing material is black, in order to guarantee that temperature-sensing color-changing material can not shine upon because of the external world, cause temperature accumulation automatic color-changing, temperature sensor is responded to the temperature of Windshield at any time, the input one-chip computer module, threshold value higher than program setting, just stop heating, extraneous light difference, the signal difference of micro controller system output, current controller can the different electric current of corresponding output, the starting resistance heating module, guarantee to make temperature-sensing color-changing material intensification variable color within the shortest time, can guarantee not make again excess Temperature, heat discoloration layer outside is pressed on Windshield with thin film, prevent the damage of outer bound pair temperature-sensing color-changing material.

Claims
