Description

The vehicle deceleration telltale

A kind of signal indicating device when the utility model relates to car deceleration.

Automobile rear all is equipped with brake taillight, is more obvious, minimizing accident, installs high-mount stop lamp in recent years on rear window additional, and this indicator lamp is made matrix type structure with more light-emitting diode usually.The deficiencies in the prior art part mainly is: it can only show a kind of state of brake, can not reflect the deceleration situation of automobile, and middle poor stability travels.Because of human eye is more blunt to the reaction that the object longitudinal velocity changes, can not show a candle to reaction to cross motion; In the vehicle ', brake is unavoidable, though the front and back car keeps certain distance, rely on lighting of stoplight stop lamp to learn the preceding vehicle brake to the vehicle drivers after travelling on, but because brake causes the degree of reduction of speed how to be difficult to learn that especially when running at high speed sudden stop, this after reaction is more outstanding in a flash, cause rear-end collision easily, just more dangerous when dark.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of braking state that both can show is provided, and can reflect the deceleration situation again, the vehicle deceleration display product that safety is good.

Can take following technical scheme to realize purpose.

The vehicle deceleration telltale is made of brake indicating lamp, also is provided with the reduction of speed detecting device, and the brake indicating lamp both sides are provided with transversely arranged reduction of speed indicator lamp, and the reduction of speed indicator lamp is connected the mouth of reduction of speed detecting device.

Under the prerequisite that satisfies the said structure requirement, specific constructive form, size as for vehicle deceleration telltale integral body, each funtion part, each zero member, connection between member, fixed form, the installation site relation, make integral type or split type etc., all can take the circumstances into consideration to set according to using needs, they can both realize purpose, guarantee the in-use performance and the effect of this telltale.

The relative prior art of the technical program has following advantage and effect:

Can show braking state, can also reflect the deceleration situation of automobile, indicator lamp is worked in the lateral variation mode, and is fairly obvious, and to travelling on the deceleration situation that the driver of back on the vehicle can learn front truck immediately, safety is good in travelling.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 3 is that A after Fig. 2 goes to cover is to view;

Fig. 4 is the A-A cutaway view of Fig. 3;

Fig. 5 is the electrical schematic diagram in the reduction of speed detecting device;

Fig. 6 is a Hall element optimum position scheme drawing in the reduction of speed detecting device.

The vehicle deceleration telltale is made of indicator lamp and reduction of speed detecting device two large divisions.Indicator lamp comprises brake indicating lamp 1 and reduction of speed indicator lamp 2, and the formation of brake indicating lamp, arrangement mode and wiring relation can be same as the prior art, be arranged on whole lamp the middle part, constitute by more light-emitting diode; The both sides that the reduction of speed indicator lamp is transversely arranged, is distributed in brake indicating lamp.The reduction of speed detecting device can be made of condenser, electromagnetic type, crystal piezoelectric type constant velocity sensor and other device, and the reduction of speed indicator lamp is connected the mouth of reduction of speed detecting device.They all have preferably test the speed, the reduction of speed indicating effect.

Among the telltale of vehicle deceleration shown in the accompanying drawing embodiment, the reduction of speed detecting device is made of fork 3, magnet 4 and control circuit, and magnet is installed in the fork lower end, the upper end is connected with anchor shaft 0 revolution; Control circuit mainly by with reduction of speed indicator lamp L1, L2, L3 ... corresponding Hall element X1, X2, X3 ... silicon control T1, T2, T3 ... constitute, the mouth of Hall element is connected with the silicon controlled control utmost point, the silicon controlled negative pole is connected with the reduction of speed indicator lamp through current-limiting resistance, and control circuit is in parallel with automobile brake lamp; Hall element is contained in magnet below in regular turn, be on the circular arc in the center of circle, the 62 ° of angular regions with the fork axis of revolution.Fork can adopt nonmagnetic various material manufacture, and it can freely rotate around 0, is sagging shape; Hall element UGN3075T successively decreases by the inertia motion direction spacing of fork and is arranged in order, is advisable with magnet maintenance 5mm distance.Shown in accompanying drawing 3,4,5.

Among the embodiment, the indicator lamp of vehicle deceleration telltale is that brake is designated as totally 10 of central double light-emitting diodes, reduction of speed is designated as transversely arranged each 10 the LED-type structure in both sides.Shown in accompanying drawing 1,2.Whole indicator lamp only is made up of 30 light-emitting diodes, and under the prerequisite that assurance function requires, used device is few, the saving energy.Light-emitting diode is all put light current about 1 ampere, because Hall element has auto-lock function, can keep conducting state after the triggering, after so automobile stops through brake, the light-emitting diode of not lighted can be not shinny, that has lighted still lights, and the whole show state that visually keeps after the brake is till the driver lifts brake pedal and stops power supply.

The reduction of speed telltale is loaded on the automotive rear-view window, or after only indicator lamp being installed in car.The driver gently touches on the brake, and vehicle does not have reduction of speed, and totally 10 light-emitting diodes of at this moment middle two rows light; During slow the brake, brake is afterburning gradually, vehicle is reduced to fully through a segment distance from certain speed and is stopped, in this process, middle two row's light-emitting diodes are lighted simultaneously, can be along with reduction of speed be lighted to both sides one by one from L1, reduction of speed is anxious more light many more, two rows light simultaneously in the middle of during sudden stop, light successively rapidly from L1 to L10.It doesn't matter for above-mentioned several situation and moving velocity, only relevant with the degree of reduction of speed, not controlled by the driver, and vertical reduction of speed of vehicle is become horizontal demonstration, and this just gives driver after travelling on highlight indication.

When braking automobile, under effect of inertia, magnet 4 is center of circle motion with O, during near Hall element X1, make its conducting, the X1 that is switched on drives silicon control T1 conducting again, T1 drives corresponding two light-emitting diode L1, luminous, and these two light-emitting diodes are installed in the position of the double light-emitting diode of indicator lamp both sides respectively, shown in accompanying drawing 1～5.Two light-emitting diodes of the Hall element of X2 position and silicon control T2 combinational circuit and position L2 link, in case will be lighted by magnet drives, each position, back and the like.Inertia is big more, and the magnet movement radian is big more, the Hall element of driving is many more, light-emitting diode to both sides light successively many more, human eye is produced each visual impact, take measures rapidly to step up vigilance.When automobile travels with same speed, the magnet freedom is sagging, be in the A position, their weight is born by center shaft 0.During brake, inertia changes into motion fully, because of magnet is done circular motion, magnet is far away more from sagging position, it is big more to separate the component that overcomes own wt from inertia motion,, change by the sinusoidal function rule, promptly perpendicular to the increase of automobile sport direction weight perpendicular to ground so should act in a diametrically opposite way in the installation site of Hall element, press the cosine function rule and set, the spacing in descending order causes even effect.The magnet movement angle is about 60 degree when the experiment sudden stop.Accompanying drawing 6 is that 62 of benchmark is spent lines friendship circular arcs in the E point with the Y-axis, is parallel to the X-axis straight line from the E strokes and dots and hands over Y-axis in the F point, point is divided into 9 parts from F to A, gets 10 points, is parallel to the straight line of X-axis after these strokes and dots, the intersection point of these straight lines and circular arc is exactly the best position of Hall element.

From cost cost, service life, to the tolerance of ambient temperature conditions, aspects such as aseismicity consider, accompanying drawing illustrated embodiment simple in structure, easy to maintenance, easy to manufacture, good combination property.Particularly big to component parameter discreteness tolerance, even the parameter substantial deviation can not influence final effect yet, as commercially available magnet, its magnetic-field intensity all can use to 2000 Gausses from tens Gausses, use through long-time with 2000 Gauss's magnet, degenerating to tens Gausses does not influence display effect yet.
