Abstract

A synchronous vehicle steering follow-up moving headlight relates to a preposing spotlight of a motor vehicle, which is an improvement proposed aiming at the reality that the road condition at one side of a curve can not be seen clearly when the diver drives at night, so as to influence on the subjective judgment of the driver and further to be easy to have danger. The preposing spotlight is characterized in that: the front end of a headlight assembly is supported and fixed by a locating rotating shaft and the rear end of a headlight is connected with a program control rotating system arranged under the headlight by a junction valve rod; the program control rotating system is composed of the junction valve rod, a headlight rotating disc, a rotation controller, a transmission line and a sensor; wherein, the rotating disc is controlled by the rotation controller, when the vehicle turns, the headlight can be driven to move following the vehicle and the sensor is fixed on a traversing mechanism of a front axle shaft of the motor vehicle by the transmission line. The preposing spotlight achieves the beneficial effects that when the driver drives at night, the lighting headlight of the head end can turn along with the rotation of a steering wheel, so as to ensure the light at the pavement to be consistent with the direction of driving and can avoid the accident occurring caused by the situation that the road condition can not be seen clearly at the curve and the position where the road condition is bad.

Description

Driving synchronously turns to the servo-actuated headlight

Technical field

The utility model relates to illumination, particularly the preposition illuminating lamp of self-propelled vehicle.

Background technology

The night running of power actuated vehicle is to be unable to do without illumination, for automobile, because of speed fast, the required distance of lamp photograph is wanted more farther toward contact, and this maintains static the car light traditional, when being in negotiation of bends or road conditions complicated situation, light lags behind and turns, to making chaufeur not see the road conditions of bend one side, influence its subjective judgement, and then very easily cause danger.This situation does not change so far.

The utility model content

Based on above-mentioned existing problems, but the utility model proposes the servo-actuated headlight that a kind of sync direction dish rotates, its purpose just is to improve the safety of night travel, and solve has illumination clearly to guarantee in the same old way under the bend highway section, can judge in advance accurately, and then reduce accident rate.

Architectural feature of the present utility model is:

(1) with the front end of big lamp assembly with a positioning rotating shaft support fixation, connect the program control rotary system of valve rod below headlight in the rear end of headlight by one and link to each other.Its mode of operation is that the rotating disc on the program control rotary system can drive the positioning rotating shaft rotation of the rear end of big lamp assembly around front end when rotating;

(2) program control rotary system is an electronic type control system, it is a circular group zoarium, by connecting valve rod, the headlight rotating disc, Rotation Controllers, transmission line and sensor constitute, wherein, rotating disc be combined in controller above, coaxial and be one with controller, rotatable, and the connection valve rod that passes through above the dish is connected the rotation of drive headlight with the headlight rear end, Rotation Controllers is the executive item that the control rotating disc rotates, sensor places on the direction machine of self-propelled vehicle propons, the direction of front tire can be changed signal and deliver to controller by transmission line, promote rotating disc and do synchronous low-angle rotation, and then drive big lamp assembly and rotate, can realize turning to synchronously of light and tire around positioning rotating shaft.

(3) circuit structure of Rotation Controllers includes: sensor, signal processing circuit, shaping circuit, control circuit, power-supply circuit and stepper motor driving circuit.

Operational process of the present utility model is: when vehicle is turned, automobile-used pressure sensor is transferred to the contact connection signal of a left side or dextrorotation the signal processing circuit of controller, drive stepping motor stepping under the control at control circuit after amplifying shaping, then the driven rotary dish rotates, under the affecting that connects valve rod, the headlight rear end is rotated the light sync direction disc spins that makes.Its functional block diagram is seen Fig. 4, and physical circuit is seen Fig. 5.

The technique effect that the utility model reached is, the lighting headlight of its headstock can be followed the rotation of bearing circle and rotated during night travel, thereby guaranteed that road surface light is consistent with direction of traffic, can avoid seeing in bend and the bad part of road conditions please the road surface situation and have an accident.

The specific embodiment

Shown in the adjoint 1～3, embodiment of the present utility model is a roadlice.Its operation scheme is: sensor 2 is automobile pressure sensors, dock with propons interface 11 by interface 1, its sensing mode is, under circuit connection situation, turn sign on the direction machine 12 is accepted by sensor 2, in sensing transmission line 3 is transferred to electronic process controller 4, do signal conditioning and amplify shaping, under the controlling and driving of control circuit and driving circuit, with step motor drive, and then 8 rotations of driven rotary dish, then connect valve rod 9 and and then rotate, affect big lamp assembly 6 to rotate around positioning rotating shaft 7, then the rotation of headlight 6 just with the rotation of bearing circle synchronously in the same way, make automobile in the turning process at night, its illumination indication is road surface to be turned.Wherein, among Fig. 2, big lamp assembly 6 includes lamp bracket, lampshade, bulb, snoot and circuitry lines 5.

Functional block diagram about electronic process controller 4 is provided by Fig. 4, and its work control has switch in addition, makes it only to enable when night travel illumination.

Fig. 5 has provided the control circuit of electronic process controller.Stepping motor in the program controller is a control element that pulse electrical signal is changed into angular transposition or displacement of the lines, its rotating speed of motor only depends on the frequency and the pulse number of impulse singla, add an impulse singla to motor, motor just can turn over a step size, the speed of rotating and the frequency of impulse singla are directly proportional, it must be worked under the Crossed Circle impulse singla, change the direction of rotation by the order that changes the dicyclo pulse, The whole control is by a micro controller system, the step-by-step control system that digital signal processor and step motor drive chip constitute two-phase hybrid carries out, and can realize synchronizing, half step, 1/4 step and the micro-step movement that can reach 400 segmentations at most.The rotating disc 8 that connects with headlight drives by stepping motor.

The utility model technology is equally applicable to truck, trac. and other truck conspicuity marking, and institute occupies very little, only is that the fixed form of front headlight is changed, and other increases by a cover steering controlling device.
