Description
Technical field
The utility model relates to a kind of for the Vehicular illumination device field, and specifically, the utility model relates to a kind of AFS angle control executive device for Vehicular illumination device.
Background technology
In the prior art, self-adaptive headlamp system (AFS, Adaptive Front LightingSystem) can be realized the follow-up adjustment of automotive headlamp direction of illumination.Concrete in AFS, the irradiation light of automotive headlamp can be adjusted according to the actual travel road conditions.For example, its direction of illumination can be no longer remains consistently with vehicle heading, but can make real-time adjustment according to a plurality of incoming signals of travel condition of vehicle.Strengthen the illuminating effect of automotive headlamp like this, thereby improved the safe driving of vehicle performance.For example, in self-adaptive headlamp system AFS working process, can be with reference to a plurality of signal inputs of travel condition of vehicle, comprise steering wheel angle signal, vehicle speed signal, country beam signal, passing light signal, signal and AFS control signal etc. reverse gear, send the action that electric machine control instructs to control motor as a reference and according to default control policy with above-mentioned information, drive the adjustment that head lamp is made respective angles by AFS angle control actuating unit.Yet, present widely used AFS angle control actuating unit mainly contains two kinds, a kind ofly constituted by gear pair, because this mechanism is complicated, has more mechanical drive pair, when the drive head lamp is made angular adjustment, efficient is low, carry-over moment is little, steady phenomenon such as angle of arrival jump often, thus make the accuracy of AFS angular adjustment to guarantee.Another kind is directly controlled actuating unit for motor output shaft and is carried out angle control, too simple owing to structure for this mechanism, there is not the middle transition device, cause in the head lamp angular adjustment its running stroke unsmooth, often steady phenomenon such as angle of arrival jump also can cause the accuracy of AFS angular adjustment low at last.
The utility model content
The purpose of this utility model provides a kind of AFS angle controller, and simple in structure, transmission is less, realizes the steady and accuracy of head lamp angle control.
For solving above-mentioned purpose, the utility model comprises housing, the performance element that is arranged on the propulsion source in the housing and is used for driving AFS head lamp mechanism, double reduction mechanism is set between described performance element and the propulsion source, described first order speed reduction gearing comprises first gear and second gear on the output shaft that is arranged on propulsion source, described second stage speed reduction gearing comprises and the worm screw of the coaxial setting of second gear and the worm gear that cooperates with worm screw formation worm and gear, the fill order comprises be used to the output shaft of the AFS head lamp mechanism that is connected and is contained in retarder on the output shaft that engagement arranges between first gear and second gear.
Adopt said apparatus, because it is simple in structure, gear pair is less, occupy little space, can reach good deceleration effect through two reduction gear, and worm and gear cooperates, the effect that not only has deceleration increases the effect of square simultaneously in addition, can realize stationarity and the accuracy of AFS angle control.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is for installing the scheme drawing of the utility model housing;
Fig. 3 is contained in scheme drawing in the housing for the utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises housing 50, the performance element 30 that is arranged on the propulsion source 10 in the housing 50 and is used for driving AFS head lamp mechanism, between described performance element 30 and the propulsion source 10 double reduction mechanism is set, described first order speed reduction gearing comprises first gear 11 and second gear 21 on the output shaft that is arranged on propulsion source 10, described second stage speed reduction gearing comprises and the worm screw 22 of second gear, 21 coaxial settings and the worm gear 31 that cooperates with worm screw 22 formation worm and gears, performance element 30 comprise be used to the output shaft 32 of the AFS head lamp mechanism that is connected and be contained in retarder 40, the first gears 11 on the output shaft 32 and second gear 21 between engagement arrange.This structure has only two pairs of gear meshing, and transmission is few, the driving efficiency height, and the moment of transmission is big.Can reach good deceleration effect through two reduction gear, and the worm and gear cooperation, not only have the effect of deceleration, increase the effect of square simultaneously in addition, can realize stationarity and the accuracy of AFS angle control.For the angular adjustment to head lamp is accurately controlled, need to detect in real time output shaft 32 rotational angle vertically, so in performance element 30 upper ends sensor 40 is housed, the lower end links to each other with AFS head lamp mechanism, so just can detect output shaft 32 rotational angle vertically in real time, and feed back to the realization of AFS control unit to the closed loop control of propulsion source 10, make timely and adjusting.
As shown in Figure 2, for easy for installation and save the space, specially done one with the mutual corresponding shell 50 of AFS angle control executive device, each parts of AFS angle control executive device are installed in respectively in the relevant position in the housing 50.Be installed in corresponding bearing seat as the bearing that be used for to support each, motor is installed on the motor bearing, worm gear 31 places is installed has a hole of passing through for output shaft 32 etc.
During concrete work, described propulsion source 10 is a motor, propulsion source 10 adjusts according to the assembly signal that motor chip transmits, propulsion source 10 output torques drive first gear 11 and rotate, first gear 11 is meshed with second gear 21, thereby driving second gear 21 rotates, and then rotated by the worm screw 22 that second gear 21 drives coaxial setting, worm gear 31 on worm screw 22 and the performance element 30 constitutes worm and gears and cooperates, propulsion source 10 output torques are played the effect of deceleration increment, like this, propulsion source 10 output torques are delivered on the performance element 30 through double reduction mechanism, and drive the output shaft 32 rotation output torques that are arranged on the performance element 30, thus realize being installed in the AFS head lamp mechanical operation of output shaft 32 lower ends, make corresponding angle control.At performance element 30 sensor 40 is set, can the axial rotation angle of performance element 30 be detected in real time, and feed back to the AFS control unit, realize the closed loop control to propulsion source 10, make timely adjustment accordingly.
