Description

Motor turning rudder position intelligent display device
Affiliated technical field
The utility model relates to a kind of wheel steering rudder level display apparatus, and especially a kind of automobile instrument panel top of being positioned over is used to indicate automobile veer dish when turning make the automatic display unit that turns to the rudder position to change.
Background technology
Along with the fast development of Domestic Automotive Industry, automobile and people's lives are got in touch more and more tightr.When you enjoy trip that automobile brings to you when convenient, whether such experience was arranged: the automobile that your household drives is difficult to pour narrow parking stall exactly into, or the curb in roadside is arrived in the tire scratching when turning at the crossing ...Along with rolling up of automobile quantity, new steerman quantity is on the increase, the number of taking driving test continues to rise, practice according to each big driving school shows, the biggest obstacle that new hand learns car is exactly to grasp the amplitude of bad turning, unclear own steering wheel rotation has so just increased the possibility that traffic accident takes place on the run from now on to the actual angle that turns over that wheel brings.
Be used for changing the travel direction of automobile in the automobile and keep the mechanism of automobile straight-line travelling to be called automobile steering system, it generally is made up of deflector and steering gear two parts.Deflector is made up of bearing circle, steering shaft, steering column etc., it is that rotation with bearing circle becomes the swing of pitman arm or the straight reciprocating motion of rack shaft, and the mechanism that handling maneuver power is amplified, deflector generally is fixed on automobile chassis frame or the vehicle body, and handling maneuver power can change transmission direction after by deflector.Steering gear is made of steering swivel, tierod, track arm etc., is wheel (steering swivel) is passed in the power and the motion of deflector output, and makes left and right wheels carry out the mechanism of deflection by certain relation.The principle of work of automobile steering system is: during motor turning, chaufeur passes through steering shaft input redirect device to the steering torque that bearing circle applies.1,2 grade of deceleration transmission pair is arranged in the deflector as reduction gear apparatus.Moment after deflector is amplified and slow down after motion pass to tierod, pass to the track arm that is fixed on the steering swivel again, the steered wheel deflection that steering swivel and it are supported, thereby changed the travel direction of automobile.
Rotate vehicle steering, by the automobile steering system transmission, the angle that vehicle front is rotated claims the vehicle front deflection angle.If any car be: bearing circle anti-clockwise rotation 0-540 degree full scale, by the steering swivel system transmission, vehicle front anti-clockwise rotation 0-30 degree angle; Bearing circle right-hand revolution 0-540 degree full scale, by the steering swivel system transmission, vehicle front right-hand revolution 0-30 degree angle.Corner of vehicle steering wheel equals 18: 1 with the ratio of front wheel angle at 540: 30, and promptly bearing circle rotates 18 degree, and front-wheel rotates 1 degree.If motor turning rudder position telltale is arranged, just can allow navigating mate know clearly very much the direction and the corner of tire, dependence experience is purely judged, improves the safety of driving.At present, no matter be that domestic brand car or joint brand car all do not have vehicle front to turn to read out instrument with corner on the automotive market of China, this patent is specialized in this.
Summary of the invention
The purpose of this utility model is to solve above-mentioned problems of the prior art, provide a kind of intelligent display driver when the direction of operating dish, to bring the device of actual turning effect to wheel, it is motor turning rudder position intelligent display device, the angle that it allows the driver allow wheel turn over when especially new hand can know own veer dish easily when driving, make things convenient for driver's operation, improve the safety of driving.
The utility model is to adopt following scheme to realize: because vehicle front makes it to rotate by the automobile steering system transmission, our imagination is installed a rotor wheel of rotation synchronously on steering shaft, the direction and the angle of rotor wheel rotation are measured by angular-motion transducer, again by the intelligent conversion circuit by the conversion of certain ratio and be presented on the read out instrument, promptly allow the driver see vehicle front turned to demonstration with corner.
A kind of motor turning rudder position intelligent display device, its concrete feature is: it comprises the rotor wheel, the angular-motion transducer of measuring the rotor wheel rotational displacement that rotate synchronously with steering shaft, also comprise an intelligent conversion circuit that links to each other with the signal output part of angular-motion transducer, the mouth of intelligent conversion circuit links to each other with read out instrument.
Above-mentioned angular-motion transducer is the device that automatically anglec of rotation is transformed into electric signal output, adopt photo-electric or potential device formula angular displacement transmitter, wherein the photo-electric angular displacement transmitter is a kind of rotation impulse producer, mechanical corner is become electric pulse, measure the corner of working shaft according to the number of pulse, it has characteristics easy for installation.
The turning cylinder of above-mentioned rotor wheel is connected by elastic coupling is coaxial with the rotating shaft of angular displacement transmitter, and a driving wheel is installed on steering shaft, driving wheel and rotor wheel are meshing with each other, and angular displacement transmitter is fixed by T shape bar and vehicle frame or vehicle body, and T shape bar also has an end sky to be enclosed within on the steering shaft.
Above-mentioned intelligent conversion circuit is by a PIC micro controller system, and sets indicator lamps, three left rudder position direction display lamps, three right standard rudder position direction display lamps and three rudder positions with PIC single-chip processor i/o mouth bonded assembly input interface, three charactron, three rudder positions and set buttons and form.
Above-mentioned read out instrument is positioned over the automobile instrument panel top, adopt the digital display of 12V direct supply, have intelligent conversion circuit and digital the demonstration in it, like this pulse electrical signal biography read out instrument that spreads out of of angular displacement transmitter, behind conversion, data handing, realize numeric display.
When bearing circle rotated, steering axles drove driving wheel and rotates, and driving wheel drives rotor wheel again and rotates; Rotor wheel rotates the back and rotates by the rotating shaft that coupler drives angular-motion transducer, makes angular-motion transducer output and the cooresponding electric signal of rotational angle, has reached to detect that vehicle front turns to, the purpose of angle; With being connected on the read out instrument after its electric signal conversion, demonstrate then, promptly turn to the rudder position to show by vehicle steering rotates and then the driving automobile front-wheel rotates direction and angle.
The beneficial effects of the utility model are: simple in structure, easy for installation, when driving, can clearly indicate the vehicle front hand of rotation and the anglec of rotation automatically, allow navigating mate know clearly very much the direction and the corner of tire, more easily handle motor turning, turn, reverse end for end, move backward, stop operations such as storehouse such as the crossing, greatly reduce the manipulation burden of navigating mate; The new hand that it is primarily aimed at the low driving age and learns car allows its left-hand seat rapidly, grasps skilled driving technique rapidly, the raising safety of driving.
