Abstract
The utility model discloses an automobile lateral follow-up lighting device, comprising a steering tie rod and an automobile light, wherein, the steering tie rod is provided with a displacement sensor which is connected with a switching controller. The switching controller is connected with a stepping motor, and the stepping motor is connected with the automobile light and drives the automobile light to rotate. The lighting device of the utility model eliminates the potential safety hazard when the automobile is driven fast. The device has smaller volume and strong adaptability, so it can be used in different kinds of vehicle types. The device is composed of electronic elements, so it is convenient to dismount and has high reliability without thinking about the factors of frictional loss, intensity and hardness.
Description
Technical field
The utility model relates to the improvement technology of the illumination equipment of automobile, especially a kind of automobile side angle follow-up illumination device.
Background technology
The function of car headlight device is to guarantee that automobile normally moves, and under the situation of insufficient light, as greasy weather, night etc., all needs the illuminating lamp of opening automobile front portion to ensure the visual field of chaufeur, prevents the generation of safety traffic accident.Car headlight device in the conventional art, mainly comprise head lamp, preceding side lamp, fog lamp etc., because its lamp housing all is fixed in and does not have rotating function on the car body, therefore when motor turning, light and direct of travel differ certain angle, and automobile lacks side lighting light on the direction of will change, can only rely on the surplus light of faint scattering to feel one's way into, cause the driver can't observe this direction condition of road surface, have potential safety hazard, cause traffic accident easily.Moreover, because the restriction of the physiological structure of people's eyes,, usually produce the collimation error when human eye during from the bright vehicle front car of turning direction side of light, in former seconds, do not see the situation of side substantially, cause traffic accident easilier.In the prior art, a kind of illumination equipment that servo-actuated turns to synchronously can be with motor turning the time is also arranged, name is called " follow-up steering car headlight device ", and the patent No. is the disclosed content of the Chinese patent of ZL92234573.2, and it is to realize turning to of illumination equipment by steel cable.What the deficiency of this kind mode was mainly reflected in employing is non-electron steering direction, and reliability is relatively poor, and structure is complicated.
Summary of the invention
The utility model is at the above deficiency of prior art, and the commentaries on classics that provide a kind of degree of automation height, turns in company with automobile synchronously is according to device.
The utility model is to adopt following technical scheme to realize: automobile side angle follow-up illumination device, comprise tierod, car light, its improvements are: displacement pickup is set on tierod, displacement pickup is connected with change over controller, change over controller is connected with stepping motor, and stepping motor is connected with car light and drives car light and rotates.Described displacement pickup is formed complete circuit by slide rheostat, contact and power supply on tierod, measures the displacement of tierod.
Illumination equipment of the present utility model, the potential safety hazard of having turned when having eliminated galloping; This device volume is less, comformability is strong, can be used for various vehicles; This device is mainly formed, easy accessibility, needn't be considered factors such as loss due to friction, intensity, rigidity, the reliability height by electronic component.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the automobile power steering principle schematic.
Fig. 2 is the utility model structural representation.
Fig. 3 is a kind of concrete structure scheme drawing of displacement pickup (part).
The specific embodiment
As shown in Figure 1, be prior art.1-deflector among the figure, 2-pitman arm, 3-steering drag link, 4-track arm, 5-tie rod arm, 6-tierod.In driving procedure, the chaufeur steering wheel rotation produces turn sign, this turn sign at first passes to deflector 1, through pitman arm 2, steering drag link 3, track arm 4, tie rod arm 5, pass to tierod 6 again, make tierod 6 produce sway; Tierod 6 sway just drive the deflection of the wheel left and right sides again, and formation turns to.This is a prior art, is not further described.
As shown in Figure 2,7-displacement pickup, 8-converter controller, 9-stepping motor, 10-car light among the figure.Displacement pickup 7 is set on tierod 6, displacement pickup 7 can be measured the displacement of tierod 6 sway, and in the form of the electric signal (curtage) that can discern with the change over controller 8 input change over controller 8, change over controller had in fact both had the function that A/D or D/A change mutually, has programmable control chip (program) in it again, can be to handling from the electric signal of displacement pickup 7 inputs, and after handling, can send rotation command to stepping motor 9, make two stepping motors, 9 synchronous forward or reverse, and rotate identical revolution.The rotating shaft of the mounting bracket of car light 10 and stepping motor 9 links together, when the forward and backward rotation of circumferencial direction is done in the rotating shaft of stepping motor 9, the mounting bracket of car light 10 can be done left and right swing synchronously, make car light 10 synchronous left and right turning to, car light 10 can be turned to along with wheel steering, reach the purpose of synchronous lateral rotation.Change over controller 8 and dynamo-electric machine 9 of step are not further described at this as the part of prior art.
As shown in Figure 3, as further improvement of the utility model, displacement pickup 7 is formed complete circuit by slide rheostat 11, contact and power supply on tierod 6, utilizes the principle of work of slide rheostat 11, measures the displacement of tierod 6 sway.(is example with the wheel right-hand rotation) specific as follows gets a bit on tierod 6, draws a contact from this point, places a slide rheostat 11 in its underpart, forms complete circuit as shown in the figure.When wheel forward during straight, automobile does not have and turns to, this not conducting of circuit, when the wheel right-hand turning to the time, tierod 6 is to left, the contact was moved to the left with resistance and was connected this moment, this moment, circuit was connected, the contact can be made as the A point at this moment; Tierod 6 continues to represent then that to left wheel continues deflection to the right that until reaching maxim Q, this moment, contact position can be made as the B point.The occurrence of electric signal when being positioned at A, B point according to the contact, can release when wheel to the right angle of inclination at O degree characteristic of correspondence signal value during arbitrary value between the Q degree.In this characteristic signal value input A/D change over controller 8, after its conversion, send instruction to stepping motor 9 again, the rotation direction of control step motor 9 and revolution, thus car light 10 is turned to along with wheel steering synchronously.
