Abstract

The utility model discloses a turning lamp controlling device for a motor vehicle, comprising a left turning lamp controller, a right turning lamp controller, a false operation control circuit and a delaying reset circuit. When an obstacle is encountered in the transforming process of the motor vehicle and a front wheel needs to make short time slewing, the delaying reset circuit comprising an electrical magnet, a switch sensor, an emitting driver, an inverter and an electric condenser can control the turning lamp to keep built-in indicating state. The device of the utility model is suitable for being installed in various motor vehicles (automobiles, electric cars, motorcycles, etc.).

Description

Electronic control device of automotive vehicle steering lamp

The utility model belongs to the motor turning lamp control device.

In the prior art, steering lamp for motor vehicle generally all adopts the control setup of mechanical or left and right toggle switch formula, the existing problem of this class control setup is in the car body steering procedure, when crop rotation is turned round in short-term before needing because of avoiding barrier (as bicycle, pedestrian etc.), can not keep the continuous indicating status of steering indicating light, mechanical control device also can't be installed on car bodies such as electric car, motor bike in addition.

The purpose of this utility model is according to the existing in prior technology weak point, providing a kind of can finish back SELF CL steering indicating light at Vehicular turn, and controls the steering lamp for motor vehicle electronic control package that steering indicating light keeps original indicating status when wheel turns round in short-term.

Below in conjunction with description of drawings groundwork of the present utility model and major technique feature.

Fig. 1 is the electric principle schematic of " steering lamp for motor vehicle electronic control package " described in the utility model.

Fig. 2 is the installation site scheme drawing of Sensor section on body of motor vehicle in this device.

According to Fig. 1, " steering lamp for motor vehicle electronic control package " described in the utility model comprises left-hand rotation lamp controller, right-hand rotation lamp controller, maloperation control circuit and delayed management circuit, and the lamp controller that wherein turns left is made up of the saturated switch 2 of button switch 1. transistors, d type flip flop 3, actuator 4 and electromagnetic relay 5 etc.; The right-hand rotation lamp controller is made up of button switch 6, the saturated switch 7 of transistor, d type flip flop 8, actuator 9 and electromagnetic relay 10 etc.; The maloperation control circuit is composed in series by two phase inverters 11,12, its input end respectively with the d type flip flop of left and right steering indicating light controller

Input end links to each other, input end leads to " O " line of putting of above-mentioned 2-D trigger respectively, and (the R reset circuit is made up of electromagnet 13, switch sensor (as dry-reed tube, electro-optical tubes, hall device etc.) 14, emitter-base bandgap grading actuator 15, phase inverter 16,17 and cond 18 etc., and the mouth of this circuit also communicates with " O " line (R end) of putting of aforementioned 2-D trigger 3,8 respectively.

When vehicle wheels turns round in short-term, can control steering indicating light and keep original indicating status this purpose for reaching, the utility model designer is located at the electromagnet in the delayed management circuit 13 on the front-axle beam 19 of steering mechanism of motor vehicle, and switch sensor 14 is located on the longitudinal tie 20 of steering mechanism of motor vehicle.Like this, be front vehicle wheel 21 when ajusting when car body moves ahead, electromagnet 13 aligns with switch sensor 14, and the sensing switch contact disconnects; For car body turns to promptly when front vehicle wheel 21 during with respect to car body deflection, longitudinal tie 20 displacements, electromagnet 13 staggers the sensing switch junction closure with switch sensor 14.

The principle of work of steering lamp for motor vehicle electronic control package described in the utility model is as follows:

(1) when need indication self-propelled vehicle turns left (or right-hand rotation), press left steering button switch 1(or right steering button switch 6), the saturated switch 2(of transistor or 7) collecting electrode aerotron 22(or 23 in) is in high level, d type flip flop 3(or 8) set, through actuator 4(or 9) drive after, electromagnetic relay 5(or 10) adhesive, left-hand rotation indicator lamp (or right-hand rotation indicator lamp) is in "on" position.

(2) pressed left steering button switch 1(or right steering button switch 6) after, left-hand rotation indicator lamp (or right-hand rotation indicator lamp) remains on "on" position, front vehicle wheel 21 is with respect to α angle of car body deflection during turnon left (or right-hand corner), switch sensor 14 closures, the emitter of aerotron 24 is in low level in the emitter-base bandgap grading actuator 15, do not have clear " 0 " pulse output, self-propelled vehicle can be turned smoothly.After the end of turning, wheel 21 is ajusted away straight way once more, and switch sensor 14 aligns with electromagnet 13, and the sensing switch contact disconnects, and the emitter of aerotron 24 is in high level.After paraphase, voltage reduces because of discharge on the cond 18, and during to the threshold value of gate circuit, phase inverter output high level causes d type flip flop 3(or 8) clear " 0 ", steering indicating light extinguishes automatically.

(3) in self-propelled vehicle turning process, need return positive wheel in short-term when walking quickly and keeping away if run into obstacle (as bicycle, pedestrian etc.), because the voltage on the cond 18 will just can reach the threshold value of gate circuit through the time delay of t=RC, so do not produce clearly " 0 " pulse when t＜RC, steering indicating light still can remain on the state of energising.

(4) if press left and right button switch 1.6 simultaneously, then d type flip flop 3,8 is in any state and all causes clearly " 0 " end R high level, makes left and right steering indicating light outage, so can correct in the driving way because the trouble that the chaufeur maloperation causes.

Apparatus function described in the utility model is perfect, and is simple to operate, easy to use, is suitable for various motor vehicles (automobile, electric car, motorcycle etc.) and installs.
