Summary of the invention
The utility model purpose is to overcome above-mentioned weak point of the prior art and a kind of electric direction varying device that can turn to by remote signal Control of Automobile back mirror is provided.Than present domestic electric direction varying device on the market, it replaces complicated panel switch with remote signal, simplify line construction in the car with programme controlled electronic circuit, have simple to operate, stable, failure-free advantage, have easy to adjust, advantage intuitively again.Be specially adapted to Oversize vehicle and high-grade car.
The utility model is realized in the following way:
The utility model is mainly by a signal transmitting unit, a signal receiving unit, a codec processing unit, and two driver elements are formed.Described signal transmitting unit is remote controller, signal transmitting unit sends out control signal, after described receiving element is confirmed signal, useful signal is sent to codec processing unit carries out signal conditioning, control two separate driver elements by the output of codec processing unit again, described driver element drive respectively the left-right rotation motor and up and down rotary electric machine to drive corresponding transmission device action, polarity of voltage by changing the direct current micromotor two ends to be realizing motor positive and inverse, thereby realizes that back mirror turns to function.
In sum, the utility model and traditional electronlmobil back mirror deflector main difference is:
What one, the conventional steering device adopted is pure circuit control motor, the wire structures complexity, and panel switch too much inconvenience is safeguarded and is used.What this patent adopted is to replace panel switch control deflector with remote controller, has simplified wiring in the car, installation and maintenance and use comparatively convenient.
Two, the utility model is gradual change when turning to the orientation to change, and can allow the user adjust to suitable angle orientation as required largely.
Three, the impulse singla that remote controller sent just carries out Filtering Processing in content before sending, and guarantees interference-free.And in signal receiving unit, all have the study sign indicating number in the corresponding address to respond the fixed signal of sending, only the signal that the remote controller of its pairing is provided is effective.Guaranteed the unicity of communication, particularity and stability.
Four, the study sign indicating number in the signal receiving unit, be similar to scratch pad memory, in case pairing remote controller disappearance, damage, the user can be by changing remote controller, and wipe study sign indicating number in the receiving element address, write again and can continue the purpose used to reach with the study sign indicating number of new remote controller response.
Therefore, the utlity model has following advantage: have the electric powered steering function of conventional electric control back mirror deflector, and improve on its basis, simplified wire structures in the car greatly, simplify and fallen loaded down with trivial details panel switch; Have again height single, accurately, be not subject to the communication function disturbed, guarantee the accurate execution of order; In addition, the study sign indicating number in the receiving element address has erasable function, and the continuation that makes the user can more renew under the situation of disappearance remote controller is used.
