Abstract
The utility model relates to a brake dynamic display device for a motor vehicle, and comprises a cursor display plate formed by a plurality of unit luminescence pieces, a pressure sensor positioned in a hydraulic brake pipeline or an air pressure brake pipeline, and a control circuit formed by a display drive and a triode amplifying circuit. The pressure sensor leads the weight control condition information during vehicle brake for the driver to be transferred to the display drive, and a LED luminescence piece holds obvious section display through the driving. The device can solve the dynamic display problem in brake procedure during the vehicle running.
Description
Technical field
The utility model relates to a kind of automobile brake read out instrument.
Prior art
The employed braking read out instrument of current mobility car comprises high-order display lamp, dummy lamp etc., all is the switching mode display control unit.It is by a contactor that is installed on brake pedal or the pressure line, is switched on after the driver steps on brake pedal, and the control display lamp sends speed-slackening signal.Above-mentioned braking read out instrument exists following shortcoming: the demonstration braking mode is a single form, only can show braking and non-braking two states, can not the weight of braking mode be shown dynamically, to point out back car driver, according to circumstances make correct judgement, take appropriate measures the generation that avoids traffic accident.
Summary of the invention
A kind of self-propelled vehicle dynamic display device described in the utility model can solve in the running car, the dynamic demonstration problem of braking procedure.
A kind of self-propelled vehicle braking dynamic display device described in the utility model is formed the cursor display panel by a plurality of illuminating parts; Illuminating part in the described cursor display panel is to be the unit with the plurality of sections, to show the different braking state; The control circuit of described cursor display panel comprises that a zero correction that is installed on the pressure sensor in hydraulic tubing or the pneumatic circuit, the LED point type/bar shaped display driver that is connected with described pressure sensor, described actuator, full scale proofread and correct resistance, be connected in one group of transistor amplifier of described driver output end; One end of described plurality of sections unit illuminating part is connected respectively with described transistor amplifier mouth, another termination power supply anode.
Aforesaid a kind of self-propelled vehicle braking dynamic display device, pressure sensor wherein can be the silicon X-shaped pressure sensor of Motorola, can also be strain gauge pressure sensor or capacitive pressure sensor.
A kind of self-propelled vehicle braking dynamic display device described in the utility model is by being installed in the pressure sensor on the brake system, weight state of a control information in the car brakeing is sent the driver to display driver, carrying out tangible section through its driving LED luminescence component shows, it is the dynamic demonstration of braking procedure, make back vehicle drive person can make in time the braking situation of front truck, judge exactly, reduce because of braking the untimely traffic accident of knocking into the back and causing.
Description of drawings
Fig. 1 is the schematic circuit diagram of a kind of self-propelled vehicle braking dynamic display device described in the utility model.
Fig. 2 is the enforcement illustration of a kind of self-propelled vehicle braking dynamic display device light-emitting diode segmenting unit described in the utility model.
The specific embodiment
Physical circuit of the present utility model can be referring to accompanying drawing.The pressure sensor that is installed on hydraulic pressure or the compression air brake pipeline system can adopt the silicon X-shaped pressure sensor of Motorola, also can adopt strain gauge pressure sensor or capacitive pressure sensor.Described pressure sensor changes into voltage change signal with the variation of the pressure in the pipeline, and it is sent into one 10 grades LED point type/bar shaped display drivers, as LM3909, LM3914, LM3915 etc.Be connected with the armature contact end of adjustable resistance R14 at 4 pin of described actuator, 8 pin are connected with the armature contact end of adjustable resistance R13.Described resistance R 14 is the zero correction resistance of this actuator, and R13 is that the full scale of this actuator is proofreaied and correct resistance.Adjust above-mentioned two resistance, the pressure signal of pressure sensor can be converted to the voltage signal of 0.5-4.5V.Described driver output end is connected with an end of plurality of sections unit illuminating part respectively.The gauge mouth that drives in the present embodiment is to be connected by the end of one group of amplifying triode with plurality of sections unit illuminating part, and the power supply anode of this device is connected with the other end of described plurality of sections unit illuminating part.
The cursor display panel of this device can adopt single, is divided into the arrangement (referring to Fig. 2) of 11 lattice (unit).Wherein middle one lattice (6 lattice) are set to red and green color and show, and are red for the acceleration pedal state shows, the demonstration that green is the speed of a motor vehicle when zero is orangely got back to the initial position for acceleration pedal, the demonstration of the speed of a motor vehicle when zero.5,7 lattice are that former car braking shows, 4,8 lattice show for the braking mode first module, be set at nonskid braking, 3,9 lattice show for the dynamic Unit second of braking, it is moving to be set at recasting, and 2,10 lattice are dynamic the 3rd section demonstration of braking, is set at and increases the weight of braking, 1,11 lattice are set at emergency braking for dynamic the 4th section demonstration of braking.More than show and be redness.
