Изобретение относитс к измерительной технике и может быть использовано дл контрол положени фар любых транспортных средств.The invention relates to a measurement technique and can be used to monitor the position of the headlights of any vehicles.
Известен прибор дл контрол положени фар транспортных средств, содержащий измерительную головку с фотоприемниками и измерительной системой 1.A device for monitoring the position of vehicle headlights is known, comprising a measuring head with photodetectors and a measuring system 1.
Недостатком этого прибора вл етс низка чувствительность по углу отклонени оси фары от оптической оси измерительной головки, обусловленна вли нием рассе нного света, что приводит к снижению точности установки фары в заданном положении.The disadvantage of this device is the low sensitivity of the angle of deflection of the axis of the headlight from the optical axis of the measuring head, due to the influence of scattered light, which leads to a decrease in the accuracy of the headlight in a predetermined position.
Цель изобретени - повышение чувствительности прибора к углу отклонени оси фары от оптической оси измерительной головки.The purpose of the invention is to increase the sensitivity of the device to the angle of deflection of the axis of the headlight from the optical axis of the measuring head.
Указанна цель достигаетс тем, что в приборе дл контрол положени фар транспортных средств, содержащем измерительную головку с ф-отоприемниками и измерительной системой, каждый из фотоприемников снабжен цилиндрической блендой, ось которой наклонена к оси измерительнойThis goal is achieved by the fact that, in a device for monitoring the position of vehicle headlights, containing a measuring head with f-detectors and a measuring system, each of the photoreceivers is equipped with a cylindrical blend, whose axis is inclined to the measuring axis
головки под углом, равным углу рассе ни регулируемой фары.head at an angle equal to the angle of the scattered adjustable headlights.
Кроме того, измерительна система выполнена в виде суммирующего усилител , вход которого соединен с выходами фото5 приемников, а выход соединен с измерительным прибором.In addition, the measuring system is designed as a summing amplifier, the input of which is connected to the outputs of photo5 receivers, and the output is connected to the measuring device.
На фиг. 1 изображен прибор, общий вид; на фиг. 2 - то же, вид спереди; на фиг. 3 - измерительна головка.FIG. 1 shows the device, a general view; in fig. 2 - the same, front view; in fig. 3 - measuring head.
° Прибор состоит из основани 1, на котором установлены стойки 2 и 3. На стойках 2 и 3 установлена каретка 4 с возможностью вертикального перемещени при помощи руко тки 5 по зубчатой рейке 6,° The device consists of a base 1, on which racks 2 and 3 are installed. On racks 2 and 3, a carriage 4 is installed with the possibility of vertical movement with the aid of a handle 5 along the toothed rack 6,
,5 выполненной на стойке 2. На каретке 4 закреплен стержень 7, на котором с помощью щарового шарнира 8 закреплена, 5 made on the rack 2. On the carriage 4 fixed rod 7, on which with the aid of the ball joint 8 is fixed
