The utility model discloses when sunshine reaches certain intensity, the sunshade cloth is put down in motor corotation, when the driver prepares to drive, can press the control and press the button, makes the motor reversal, packs up the sunshade cloth, easy operation, convenient to use, the sunlight has effectively reduced the temperature in the car when strong.
Description
Technical field
The utility model relates to a kind of sunshade device for automobile, is specifically related to a kind of automatic sun shading device for automobile.
Background technology
Hot summer, automobile can be subjected to the irradiation of sunburst when stopping, vehicle interior temperature sharply raises, can cause very big discomfort to the chaufeur that the preparation of just having got on the bus is driven, so in the ordinary course of things, chaufeur must be manually when stopping sun shield the front windshield cover of car on, reduce the irradiation of sunlight, reach the purpose that reduces temperature.But this kind method is very inconvenient.
The utility model content
For addressing the above problem, the purpose of this utility model provides a kind of automatic sun shading device for automobile, and is convenient, reduces external source, saves cost.
The apprizing system of sample treatment plant reaches above-mentioned technique effect for realizing above-mentioned technical purpose, and the utility model is achieved through the following technical solutions:
A kind of automatic sun shading device for automobile comprises puggaree and solar panel, and described solar panel connects controller, actuator and motor successively, and described controller passes through storage battery power supply.
Further, the testing circuit of described solar panel comprises: current sensor, voltage ratio translation circuit and AD conversion chip.
Further, described controller is single chip computer AT 89S52.
Further, described actuator is L298N.
The beneficial effects of the utility model are:
When the utility model reached certain intensity at sunlight, motor just changeed, and put down puggaree, when chaufeur is prepared to drive, can press control and press button, make the motor counter-rotating, pack up puggaree, simple to operate, easy to use, effectively reduce the temperature in the automobile when sunshine is strong.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification sheets, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is part-structure scheme drawing of the present utility model;
Fig. 2 is solar panel of the present utility model and single chip computer AT 89S52 connection diagram;
Fig. 3 is the pin connection diagram of single chip computer AT 89S52 of the present utility model, L298N and motor.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Referring to shown in Figure 1, a kind of automatic sun shading device for automobile comprises puggaree and solar panel, and described solar panel connects controller, actuator and motor successively, and described controller passes through storage battery power supply.Solar panel directly is converted to direct current energy to solar power, and the electric energy that controller control solar panel produces drives motor.
Further, the testing circuit of described solar panel comprises: current sensor, voltage ratio translation circuit and AD conversion chip.Referring to shown in Figure 2, for detecting described solar cell panel voltages signal and current signal in real time, need at first current signal to be converted to voltage signal through described current sensor, again the magnitude of voltage after the current conversion and solar array voltage signal are transformed to the scope that the AD conversion chip can receive through described voltage ratio translation circuit afterwards, send described AD conversion chip TLC2543 passage 0 and passage 1 respectively, after described AD conversion chip is converted to digital signal with described solar panel current signal and voltage signal, send described controller.What data communication was adopted between described TLC2543 and the described controller is the mode of serial communication, as long as carry out the connection of four signal line, is respectively chip selection signal CS, clock signal clk, and data shift out Dout, and data move into Din.
Further, described controller is single chip computer AT 89S52.
Further, described actuator is L298N.
When automobile driver stops, open described solar panel, described solar panel produces voltage through illumination, be divided into two-way, one the tunnel delivers to and charges the battery after booster circuit (2V-6V) boosts, A/D convertor circuit is delivered to through bleeder circuit (being below the 3V after the dividing potential drop) in another road, carry out digital to analogy conversion and (adopt the 11 tunnel 10 bit serial control AD of Texas Instrument, TLC2543, its precision reaches 3mV when REF is 3V), the voltage digital amount that obtains is delivered to described single chip computer AT 89S52 and is carried out data storage and analysis; Described micro controller system starts described motor through described actuator L298N and just changes, and puts down described puggaree, just can put down puggaree fully by calculating described motor rotation 5S, and this moment, described motor stopped, and described solar panel also quits work.When chaufeur is got on the bus, can pass through the described electric motor starting of Keyboard Control, this moment, described puggaree was gone up in described motor counter-rotating, had finished the sunshade process one time.
Referring to shown in Figure 3, the AT89S52 micro controller system produces corresponding impulse singla, by P2 mouth (P2.0, P2.1, P2.2, P2.3) output, P2.0 wherein, the P2.1 mouth connects ENA, the stall of ENB control control motor, P2.2, the P2.3 mouth connects IN1, IN2, control motor positive and inverse.L298N has 15 pins.
L298N motor rotary state coding is as shown in table 1.
