Freeze 4 two sides of baffle to be respectively placed in the slideway of 5 two sides of roof, the bottom of glass for vehicle window 6 is equipped with groove 4.When steering engine 1 drives machinery
Antifreeze baffle 3 is pushed into two slideways, and reaches groove 4 along slideway by pushing mechanism, is completely covered by glass for vehicle window 6, is reached barrier
The effect of steam.
The driving axis connection stepper motor of steering engine 1.Shaft 1-6 and spinneron 1-2 are distinguished in the both ends oscillating rod 1-3 and length is straight
Catch bar 1-3 connection.
Such as Fig. 4, shown in 5, control section uses 51 class single-chip microcomputers 2.51 class single-chip microcomputers 2 include main control chip 2-1, temperature and humidity
Sensor 2-2, temperature and humidity show liquid crystal display 2-5, early warning buzzer 2-3, upper electrical switch 2-6, signal pins 2-7, independent operation
Key 2-4.51 class single-chip microcomputers 2 connect steering engine 1 by data line.Two Temperature Humidity Sensor 2-2 are separately mounted to inside and outside car body,
Two Temperature Humidity Sensor 2-2 detect car body inside and outside temperature difference, when temperature difference is greater than certain value, issues early warning, pass through triggering
Independent operation key 2-4 in 51 class single-chip microcomputers 2 sends pwm wave to steering engine 1, controls steering engine 1 and stepper motor, drives mechanical
It is chimeric with automobile lower grooves 4 that pushing mechanism pushes down antifreeze baffle 3 from roof 5, covers in glass for vehicle window 6, by glass for vehicle window 6
Completely cut off with extraneous steam, and then prevent frost, when to be driven, open and open key, antifreeze baffle 3 removes automatically, Ji Kejin
Row normal driving.
Temperature Humidity Sensor 2-2 in 51 series monolithics even draws buzzer warning 2-3 by main control chip 2-1, realizes
The test warning function of temperature.
51 class single-chip microcomputers are STC89C52 single chip.STC89C52 single chip acquires in real time and monitors temperature and humidity situation, surpasses
Desired indicator is alarmed out, and STC89C52 single chip connects steering engine by three data conductors, passes through key3, key4 key hair
Different pwm waves control steering engines or so operating is sent, to realize that a whole set of pushing meanss are pushed ahead or to after-contraction.
Specific embodiments of the present invention:
1. the temperature sensor functionality using 51 class single-chip microcomputers carries out test and early warning to temperature
The index for judging whether to cause frost is to detect the temperature and humidity of air, and when reaching certain value, single-chip microcontroller is issued
Alarm, demonstrates the need for taking corresponding safeguard measure, since 51 series monolithics have Temperature Humidity Sensor and buzzer warning function
Energy module carries out certain improvement using its original development code, it will be able to realize the test warning function of temperature.
2. being that single-chip microcontroller sends the principle that pwm wave controls steering engine or so operating by key according to 51:
It controls signal and chip is modulated by the channel entering signal of receiver, obtain DC offset voltage.There is one inside it
Reference circuit, generation period are 20ms, and width is the reference signal of 1.5ms, by the DC offset voltage of acquisition and potentiometer
Voltage compares, and obtains voltage difference output.Finally, the positive and negative positive and negative rotation for being output to motor drive ic and determining motor of voltage difference.
When one timing of motor speed, potentiometer rotation is driven by cascade reduction gearing, so that voltage difference is 0, motor stalls.Rudder
The control of machine generally requires the when main pulse of 20ms or so, and the high level part of the pulse is generally 0.5ms-2.5ms model
Angle control segment pulse in enclosing, total linear spacing 2ms.By taking 180 degree angle servo as an example, then corresponding control planning is this
Sample: 0.5ms-- degree；1.0ms--45 degree；1.5ms--90 degree；2.0ms--135 degree；2.5ms--180 degree；Steering engine follows spy
Property: assuming that steering engine is stablized in A point now, at this time CPU issues a pwm signal, and steering engine turns to B point by A point at full speed, at this
A period of time is needed in the process, and steering engine can just move to B point.Retention time is Tw, and as Tw >=△ T, steering engine can reach mesh
Mark, and have remaining time；As Tw≤△ T, steering engine cannot reach target；Theoretically: as Tw=△ T, system is most coherent, and
And steering engine movement is most fast.W is not quite similar in real process, and limit △ T when coherent motion is relatively difficult to calculate.When
When pwm signal with minimum change is that (1DIV=8us) successively changes, the resolution ratio highest of steering engine, but speed can slow down.When
Steering engine is changed to more large torque, when mechanical driven rod structure is more improved, can be applied to entity automobile.
3. steering engine drives mechanical driven bar, baffle is pushed into sliding slot to fixation
The knowledge of certain mechanical structure is applied, catch bar utilizes two shafts, a straight-bar, and end connects baffle,
The structure of automobile is also accordingly improved simultaneously, car body installs two slideways, when steering engine running, turns left, shrinks, turn right
Baffle is then pushed to run along slideway, until just chimeric, a whole set of pushing meanss are placed on roof location, and folding shrinking enters ceiling,
Larger space will not be occupied.With range: this system is suitable for all automobiles, for preventing vehicle window frost.
It, can be more perfect and quasi- using special industrial class or other precaution devices, function for temperature and humidity early warning part
Really.Single-chip microcontroller controls steering engine operating, can be using the even more advanced single-chip microcontroller of other models, such as stm32 series, control
Angular range, frequency, can with isomorphism modify source code keep function more perfect.About the structure for pushing part, have very big
Room for improvement, if shaft connection can become hinge connection, catch bar can have retractility, or be pushed away using special electricity
Lever, the structural adjustment mode multiplicity of automobile, according to the actual situation can flexibly improve whole system.
System of the invention improves less original vehicle structure, implements and uncomplicated, the manipulation of 51 single-chip microcontrollers, no
With the steering engine of torque, mechanical driven bar can use lightweight material, and overall cost is very low, can be widely applied, and have wide
After market prospects are promoted the use of, it can effectively solve the problem that vehicle glass, both can be with by reluctant problems a series of after frost
Loss is reduced, artificial troublesome operation, and the traffic safety guaranteed is alleviated, has generally saved social cost, ensure
Social safety has very big application value and economic results in society in the long run/term.
The foregoing is merely preferred embodiments of the invention, but scope of protection of the present invention is not limited thereto, for
This field, those familiar for, the present invention can have various change and variation, should all cover of the invention
Within protection scope.Therefore, protection scope of the present invention should be subject to the protection scope in claims.
