Description
Technical field
The present invention relates to the installation or the supporting structure of a kind of signals of vehicles or illumination equipment, relate in particular to a kind of catadioptre rotational supporting structure that is applicable to automobile AFS light adjusting system.
Background technology
As everyone knows; As traditional driving lamp control apparatus; Be merely distance light and dipped beam in early days and regulate, can only be operated under a kind of fixing pattern, and Chinese utility model patent " a kind of automobile lamp composite electric dimming mechanism " (utility model patent number: ZL201020582430.6 is open/notification number: 201914159U) kind automobile lamp composite electric dimming mechanism is disclosed; It comprises the light modulation motor that has the manual regulation thumb wheel and is assemblied in the connection seat on the dipped beam pack support; The light modulation motor is fixed on the lamp housing, and adjust bar is connected with connection seat, when using the electronic dimming control system of automobile lamp; DC servo motor rotates after receiving voltage signal in the light modulation motor; Drive the flexible generation of adjust bar end wise displacement through worm-and-wheel gear, and then the dipped beam group is rotated, realize the adjustment of light light beam through connection seat; During hand adjustment, directly stir the manual regulation thumb wheel with Phillips screwdriver, it is flexible to drive the adjust bar end wise, drives the position that the dipped beam group turns to be needed through connection seat, realizes the adjustment to the light light beam.But this device has only been realized the motorized adjustment of far and near light.Because actual road usage situation, environmental aspect, climate condition or the like situation is very complicated.Such as the many die Dorfstrasses in: fork in the road, bend situation, crossing turning situation, drive on the expressway, driving, misty rain weather etc. on national highway.The also road environment of this complicacy and weather conditions just make safety traffic still have huge hidden danger.Statistics shows; Those vehicle operating specifications, vehicle safety require and the higher country of driveship in Europe; Because the traffic accident that illumination causes (if promptly by day perhaps lighting condition well complete avoidable traffic accident) reach more than 30%, the loss that causes is well imagined.Add that the vehicle that on the way goes is increasing, the increasing and allow chaufeur to drive the prolongation at age (age to 70 year old is driven in European existing permission, and the elderly's eyesight and speed of response obviously descend) or the like many factors and make that the traffic safety problem is more outstanding of old chaufeur.Under the requirement of these conditions, the AFS system arises at the historic moment.It has significantly improved in vehicle forward direction, the visuality at the four corners in the place ahead, bend place during night running; Reduce the degree of fatigue of detour driving at night effectively, thereby obviously promote the safety of detour up train at night.When vehicle bend goes; The AFS system can enlarge markedly the illumination zone and the illumination distances of passing light; The irradiated area that the AFS system can increase bend reaches about 20 degree; According to the speed of a motor vehicle measuring and calculating of 40KM/h, can increase more than 3 seconds for the driver will react surplus, it is most important for the professional driver who carries out the transportation at night often to increase driver's reaction time this point.The AFS head lamp system is as an important breakthrough of car light technology, and the safety of night travel has been produced tremendous raising, promoted the traveling comfort of vehicling lighting simultaneously greatly, so the AFS head lamp system obtained using widely.Yet; Catadioptre rotational supporting structure in the existing AFS light adjusting system is as shown in Figure 1; The catadioptre S. A. is divided into two sections; Be fixed on the two ends up and down of catadioptre 1,, form bearing pairs with head bearings 21 that are fixed on light modulation support 2 inboards and head bearings 22 respectively as upper support axle 11 and lower support axle 12.Upper support axle 11 is equivalent to by S.
