Description
Technical field
The present invention relates to a kind of car light turning device, particularly a kind of car light turning device structure that is used for the auto bulb device.
Background technology
Existing vehicle improves in order to make the safety of vehicle ' on road, self adaptation the place ahead Lighting System (Adaptive Front-lighting System and develop, AFS), as the lamp system with steering capability promptly is wherein a kind of technology, and described lamp system with steering capability must collocation have wheel word now for one group, can make car light have the function of turning to by its wheel word.
See also shown in Figure 1ly, be the perspective exploded view of the existing wheel word 1 of general industry; Described wheel word 1 is connected with Vehicular headlamps, and described wheel word 1 mainly is made up of motor 2, reducing gear 3, drive division 4, circuit card 5 and axle drive shaft 6; Described motor 2 is with gear on its output shaft 21 22 and reducing gear 3 engagements, and described reducing gear 3 again with fan type tooth row 41 engagement of drive division 4, one end of described drive division 4 is provided with the magnet 42 of tool N, S magnetic pole, and set firmly in the other end axle drive shaft 6 of drive division 4, described circuit card 5 is to be installed with inductive component 51, and described inductive component 51 is corresponding with the magnet 42 of drive division 4;
When wheel word 1 start, the circuit for detecting of being formed with inductive component 51 by the circuit card 5 of wheel word 1, magnet 42 in order to detecting drive division 4, because of the changes of magnetic field that drive division 4 rotates the magnet that produces 42 is judged by the circuit of circuit card 5, can learn axle drive shaft 6 existing positions, and with the predeterminated position judgement of making comparisons, if judge existing position and predeterminated position when inequality, then CD-ROM drive motor 2 drives reducing gear 3 and rotates also related axle drive shaft 6 rotations that make, and 6 of axle drive shafts turn to predeterminated position;
