Description
Technical field
The present invention relates to automobile sun-shade-curtain, relate in particular to a kind of control method of controlling automobile sun-shade-curtain.
Background technology
Owing to keeping out heat or other demand, on a lot of automobiles, automobile sun-shade-curtain is still installed now, abat vent is very practical product in actual use, more block the sun and intercept extraneous than the pad pasting of current trend, can open again and accept to shine upon, but abat vent causes using some inconvenience because needs manually pull while use, thereby use is fewer and feweri.
In view of the inconvenience that now manually pulls the loaded down with trivial details of abat vent and use, in the effect that can play by motor and relevant motion structure device are installed electronic control abat vent motion up and down or on the track of left and right of abat vent, thereby use easily abat vent, solve the awkward situation of present abat vent, utilize fully abat vent to play good result of use.
But in fact in use, directly control motor and very easily damage motor, if for example user controls mistake in the time that abat vent is opened in hope, motor direction is set as and is closed, and in fact abat vent at this moment in buttoned-up status, because motor directly drives abat vent motion structure device, at this moment reality cannot further be moved again, and motor can be inflicted heavy losses on; Also have because abat vent motion structure device is exposed in air, after long-time use, can produce the various situations such as corrosion, in the situation that not detecting, also be very easy to damage motor, and motor is arranged in compartment, change and maintenance all very inconvenient, therefore need various situations to monitor and control the impact on motor, and directly control motor and be also not easy to far distance controlled.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automobile sun-shade-curtain control method, solve present automobile sun-shade-curtain and cause using inconvenience owing to can only adopting manually to pull, if and it is impaired directly to pull abat vent easily to produce motor by control motor, the defect that cannot use.
