Description

Adjustable headlight of vehicle

The utility model relates to a kind of adjustable head light for the road vehicle use

For a long time, always be very difficult in many curved road up train that rise and fall night.Because public automotive headlamp is all fixed, can only illuminate the place of vehicle dead ahead certain distance, when road turns round or before descending, headlight light will depart from the road surface, make the driver not see road.

In recent years, some patent disclosures have been arranged several adjustable head lights, these adjustable head lights all are mounted on the bearing of an activity, can be divided into two classes according to the mode difference: a class is that driver's direction of passage dish comes indirect operation, as Chinese utility model patent 86203529; Another kind of is the direct manually operated of driver, as practicality novel 88205125.The adjustable headlight of last class rotates (or moving) with other parts in bearing circle or the steering system and rotates, and both characteristics of motion are corresponding one by one, makes the lighting condition of vehicle on continuous bend be greatly improved.But before turn inside diameter, because bearing circle also do not rotate, headlight is still according to the dead ahead, and at this moment light is just according to less than curve ahead.In addition, this class headlight can only horizontally rotate, can not pitching, so before descending, light is also according to less than the road surface.To the adjustable headlight of back one class, though the driver can come the direction of illumination of regulated at will headlight by drag-line or motor, but increased the weight of his burden, so that such situation can occur: before changeing sharp turn or following abrupt slope, at this moment the driver needs most and sees road clearly, removes to regulate headlight but can not rise time and efforts.

The utility model aims to provide a kind of adjustable head light, and the direction of illumination that can make it is the direction that the driver will observe all the time, and additive incrementation driver's operation is not born again.

The disclosed adjustable head light of the utility model is by projector, receiver array, control circuit and level, pitch rotation actuating unit and transferred head light to form.Its principle of work is such: when driver's desire was observed certain direction, its head will turn to this direction.Be worn over the projector accompany movement on his crown, the beam projections of sending the band directivity is to certain receptor that is fixed in his the head receiver array on every side.Control circuit is by the radio scanner array, just can determine the position of this receptor in array, it also is the direction in space of projector, relatively its former direction (being the existing direction of headlight) and now direction (being the new direction of headlight requirement) drive according to the comparative result control executing mechanism and are transferred headlight to turn left or right-hand rotation then; Face upward or nutation.Because it is very fast that said process carries out ground, the direction of illumination of headlight just is that the driver wants the direction of observing all the time like this.

Above-mentioned projector is made up of power supply, oscillator, amplifier, radiated element and catadioptre.Oscillator is used to produce the impulse singla of certain frequency, after amplifier amplifies, is launched by radiated element.Adopting catadioptre is to guarantee that transmitted beams has certain directivity and shape.Radiated element can be the electromagnetic device of emission, as light-emitting diode; Can be the device of transmit mechanical waves also, as ultrasonic transmitter, but infrarede emitting diode preferably.It only is in order to prevent the interference of other signal that emitted wave is modulated, the frequency of emitted wave (also being oscillator) is different and different with the kind of emission (or reception) element, and its frequency must not surpass the maximum frequency response range of emission (or reception) element.

Receptor in the above-mentioned array is made up of receiving element, screened housing and amplifier.Receiving element must be complementary with radiated element, is infrarede emitting diode as radiated element, and then receiving element must be infrared photosensitive tube.Such receptor rearranges array according to certain rules on the curved surface of space, the curved surface at its place preferably forms like this: formed around its generating circle garden heart of a mistake and with an axle rotation Ω angle that it coexists in this vertical surface by one section involute in vertical surface, the cross-sectional plane that is this curved surface is the garden arc, and the vertical section is an involute.The generating circle center of circle of involute is the intersection point of the vertical surface of driver's head pitch axis and his center, and the generating circle radius is approximately equal to height of head, generally is about 20 centimetres.The start position of involute is relevant with the size of this array.Its size will be decided on concrete cab space size, but the minimum installation that can not hinder receptor.All receptors are arranged by row, column, and each receptor points to the inter normal direction of the curved surface of its loca, and it is fixed so at interval: the angle that makes two adjacent receipts devices on the same cross-sectional plane is α, and the angle of two adjacent receipts devices is β on the same vertical cross-section.

Above-mentioned receiver array is lined up the rectangular by row, column except that receptor, also can be as long as delegation wherein make the horizontal direction array, and middle row are made the pitch orientation array.A kind of array before corresponding, projector only need one, and the catadioptre of projector is hollow cylinder, and the wave beam that sends is point-like.A kind of array in corresponding back, projector needs two, and one is the horizontal direction projector, and same level direction receiver array is corresponding; Another is the pitch orientation projector, and is corresponding with the pitch orientation receiver array.Both catadioptres all are slit-shaped, and orthogonal, and the ripple that sends is criss-cross (what wherein send in-line is the pitch orientation projector), and the frequency of two projector emissions is different.

Control circuit is made up of, logical circuit of arithmetic and power amplifier shaping, frequency-discriminating circuit, clock circuit, receiver array scanning circuit, latch.The central frequency of discriminator should equal corresponding emission wave frequency, clock circuit produces synchronizing signal for the The whole control circuit, scanning circuit makes signal that each receptor receives input shaper, frequency-discriminating circuit successively, after discriminator is confirmed to be cooresponding emitted wave, this receives that the Position Number of the receptor of signal just deposits among the latch B, the original content of B is put into latch A, after logical circuit of arithmetic compares A, B content, the result is exported to power amplifier, by its pushing executing mechanism, drive head light and rotate.

Control circuit can be divided into identical two parts, respectively controlling level rotation driving mechanism and pitch rotation actuating unit simultaneously, also can be only some, timesharing controlling level rotation driving mechanism and pitch rotation actuating unit.Except that shaping, frequency-discriminating circuit and power amplifier, remainder can constitute with the medium scale integrated circuit with above-mentioned functions in the circuit, and also available chip microprocessor and correspondent peripheral circuit replace.

Power element can be hydraulic pressure or compressed-air controlled, also can be other, but stepping motor preferably.

The adjustable headlight that the utility model provides adopts the head follow-up control, the illumination direction of headlight was consistent with driver's direction of visual lines all the time, do not increase driver's burden again, overcome the defective of adjustable headlight in the past, be particularly suitable for vehicle and when the travels down of complexity, use night.Transferred object if change headlight into other, just can be carried out the head follow-up control, especially be fit to some and rise the occasion use of not selling and controlling it.

Horizontal direction projector and pitch orientation projector can separate independence, but both are preferably integrated, and Fig. 4 is the combination scheme drawing of horizontal direction projector (6) and pitch orientation projector (7).

Fig. 5 is the scheme drawing of receiver array and receptor screened housing among first embodiment.Screened housing (9) is the hollow stage body of opening, and rectangle one end enters for emitted wave, and receiving element (8) places the other end.Receiving element adopts infrared photo-transistor or infrared photosensitive Darlington transistor.Screened housing must adopt the material that can not see through infrared light, as metal, makes, and to mask the wave beam of skew back direction, strengthens the directivity of receptor, prevents the influence of backward wave, improves the antijamming capability of system.

Receiver array is divided two parts, with the line receiver on the above-mentioned involute one garden arc surface as horizontal direction array (10), a middle row receptor is as pitch orientation array (11), each receptor (8,9) points to the inter normal direction of the curved surface at its place, the angle of two adjacent receipts devices is 6 ° in the horizontal direction array, and the angle of two adjacent receipts devices is 3.6 ° in the pitch orientation array.Require respectively to be 45 ° about controlled angle as headlight, respectively be 30 ° up and down, then each needs 16 receptors in the horizontal array and in the pitching array.Projector is on the horizontal axis of rotation of the driver crown, is benchmark with projector place horizontal surface, and the starting point θ of involute is-30 °, and horizontal array is positioned at+30 ° of positions.This receiver array (10,11) can be fixed on the backrest of driver seat, also can be fixed on the vehicle ceiling of driver back upper place.

Control circuit is divided into horizontal direction control and the identical two parts of pitch orientation control, controlling level rotation driving mechanism and pitch rotation actuating unit respectively.Fig. 7 is the logical diagram of the control circuit of a direction among first embodiment, and Fig. 8 is the truth table of each parts in the control circuit shown in Figure 7.(form by TG1～TG16), schmitt trigger, discriminator (IC9), multi-vibrator, frequency divider (IC8, IC11), up counter (IC1), BCD-to-decimal decoder (IC2, IC3), latch (IC9), digital comparator (IC5), reversible presettable counter (IC6), pulse distributor (IC7), pulse power amplifier and some gate circuits and switch by the analog switch group for circuit part.The array that corresponding 16 receptors are formed, this digital control circuit is four, and 16 output pins of two decoders are respectively controlled an analog switch, and analog switch is pressed the ON time sequencing, and is corresponding one by one with the tactic receptor of opsition dependent.The horizontal direction array is supposed that 16 receptors from left to right arrange, its Position Number be respectively 0,1,2 ... 15, be positioned at the driver center with No. 7 receptors, make the binary number of corresponding analog switch conducting be followed successively by 0000,0001,0010 ... 1111.The pulse square wave φ 1(1200 that produces when oscillator (E, F, G, R1, R2)～2000Hz) constantly imports up counter, after decoder for decoding, produce sequential pulse and make the conducting successively of each analog switch, the signal of receptor also enters schmitt trigger by the corresponding simulating switch successively in the array.

Schmitt trigger is made of 555 time base circuits, and its trigger level can be regulated.Surpass the trigger level of binary pair as the high level of incoming signal, then the pulse of passing through shaping of one of binary pair output and incoming signal same frequency.The frequency of this pulse is as equaling the central frequency of discriminator, and discriminator is just exported a low level, makes the latches binary number in the up counter at this moment.Because the emission wave frequency is higher than the frequency of φ 1, thus a φ in 1 cycle discriminator just can detect emitted wave, the binary number that assurance is latched is exactly the Position Number of receptor in array.

When the signal that enters binary pair is lower than trigger level, binary pair output keeps low (or high), discriminator is also kept high level, makes more new data of latch, so just can prevent the interference that backward wave causes effectively by the trigger level of regulating binary pair.

φ 2 is the clock pulse of each parts co-ordination in the circuit, and it was got through (IC11, IC8) by pulse square wave φ 1 in 20 minutes frequently, and its frequency is about 60～100 hertz, crosses to hang down just to guarantee that headlight and driver's head are synchronized with the movement.

When φ 2 uprises, start up counter, produce sequential pulse radio scanner array.As discriminator output step-down, latch just latchs up counter content (content that latchs has been represented the new direction that requires headlight) at this moment, and this counting machine is suspended.When φ 2 step-downs, up counter is resetted, for the next count cycle prepares.After the latches, comparator is compared the data B in the latch, and (the content A of forward-backward counter is the content that latchs the last time with data A in the forward-backward counter, promptly represent the former direction of headlight), for example to the horizontal direction control system, when A＞B, then represent the driver a left-handed turning α angle, require the headlight α that also turns left, at this moment comparator (output of the pin of A＞B) uprises, this high level makes pulse distributor output corresponding pulses when φ 2 uprises, through power amplification circuit, stepping motor (13) is turned left a step.The stepping angle of stepping motor (13) (behind transmission device 14,15,16) obviously also should equal α.Headlight and driver's another the causing in the sight line left and right sides like this.When φ 2 uprises, also make forward-backward counter subtract one, just B is kept in the forward-backward counter, as the former direction of this φ headlight in 2 cycles.Like this equally to the pitch orientation control system.So continuous circulation makes headlight remain servo-actuated.

If driver's head keeps motionless, or the wave beam of projector exceeds receiver array, this φ in 2 cycles the content of latch do not upgrade.Comparator (A=B) output just uprises.The content of forward-backward counter and pulse distributor is all remained unchanged, and stepping motor also is failure to actuate, and headlight keeps former direction.

Because forward-backward counter is after switching on again at every turn, its content is a ccasual, at this moment just can not represent the former direction of headlight.Therefore, need preset a numerical value to forward-backward counter after, system could normal operation.

Circuit is changed preset condition and mode of operation by a quadruple switch K2.Under the preset condition (K2 closes downwards), circuit automatically to one of forward-backward counter input predesignate several 0111, the driver only needs headlight is turned to the dead ahead of No. 7 receptor regulations, can be converted to mode of operation from preset condition.The driver is towards the dead ahead, and projector is aimed at No. 7 receptors, transferred headlight just with about his sight line to be consistent.To the pitching system, it also is similar presetting.

Manually control step motor of button (AN1, AN2) be can also pass through in preset condition, headlight and the use of some other special occasions adjusted when being convenient to preset.Because manually control requires the step frequency can not be too high, otherwise headlight is accurately located.Therefore need a frequency be several hertz pulse as the clock pulse of pulse distributor, this pulse produces with other oscillating circuit (H, I, R4, R5, C2).

Power element adopts stepping motor, switch in the circuit (K1) links with the stepping motor switch, when stepping motor cuts off the power supply (control circuit does not cut off the power supply), the K1 closure, block φ 1 pulse with low level input and door (Y1), the content of latch, forward-backward counter and pulse distributor is remained unchanged, when stepping motor is switched on, transferred the direction of headlight to remain original direction again.

Pulse distributor in the control circuit constitutes by presetting bidirectional shift register (IC7), and it can constitute the pulse distributor of " able to programme ", promptly presets different numbers, just constitutes different cycle pulse distributors.Fig. 6 is for presetting two kinds of pulse distributors that bidirectional shift register constitutes.Meet the serial input terminal RSL that moves to left as the Q2 with bidirectional shift register, Q3 meets the serial input terminal RSR that moves to right, Q4 output (or Q1 output) need not, preset 0110(or 0011,0101), just can constitute three-phase pair triple time ring distributor.Q1 as bidirectional shift register meets RSL, and Q4 meets RSR, and presets 1100(or 0110,0011,1001), just constituted four and two four clapped ring distributor mutually.

Fig. 9 is the scheme drawing of actuating unit.Actuating unit is divided into and horizontally rotates actuating unit (13,14,15,16,23) and pitch rotation actuating unit (18,19,20,22) two parts, this two parts motion be combined to form the rotation up and down of being transferred headlight.Entire mechanism is made up of base (12), stepping motor (13), cog belt transmission device (14,15,16), bent axle (23), stepping motor (18), gear drive (19,20), minor axis (22) and the fairing (17) of band Γ shape column, all parts all are installed on the base, and base links with vehicle by bolt.Stepping motor (13) is vertically fixed on the base by end face with screw (27), drives bent axle (23) by synchronous cog belt mechanism, the horizontal direction of control headlight.Stepping angle ω=i * the α of stepping motor (13), i are the transmitting ratio of synchronous cog belt mechanism, and α is the angle of two adjacent receipts devices in the horizontal direction receiver array.

Bent axle (23) two ends link to each other with base by ball-bearing casing (25,26) respectively, stepping motor (18) links by the planar section of end face with bent axle with screw (24), in the bent axle upper end one horizontal stub shafts (22) is arranged, transferred headlight (21) and quadrant gear (20) to be separately fixed at this minor axis two ends, stepping motor (18) drives the pitch angle that quadrant gear (20) is controlled headlight by gear (19).(18) stepping angle ω=i * β, i are the transmitting ratio of gear drive (19,20), and β is the angle of two adjacent receipts devices in the pitch orientation receiver array.

Magneto or permanent magnet induction formula are preferably adopted in stepping motor (13) and (18), because during vehicle ', and the frequent switch of headlight.When headlight was closed, stepping motor also should disconnect, to save electric power.As can not self-locking after the stepping motor outage, then under the effect of vibration or aerodynamic force, headlight will change of direction, makes actual direction inconsistent with required direction, after opening headlight, also will adjust direction at every turn, brings very big inconvenience to use.And adopt the stepping motor that can cut off self-lock just to overcome this shortcoming.(13) and the operating voltage of (18) also preferably equal the voltage of battery pack on the vehicle.

Stream line pattern fairing (17) had both played and had reduced vehicle ' resistance, the effect of rain-proof dust-proof again.Transferred headlight to adopt public automobile front lamp, can only be adorned one, also several can be arranged with instant and near light function.

The utility model also can adopt another embodiment: receiver array still is above-mentioned involute-garden cambered surface, but whether is divided into level and pitching two parts, but 16 * 16 receptors are lined up rectangular by row, column, as shown in figure 12.The sensing of receptor (28,29) and the interval of row, column are identical with the array among the embodiment one.Only need one with this array corresponding emitter, also form, see Figure 10, Figure 11 by power supply, oscillator, infrarede emitting diode and catadioptre, owing to have only an infrared diode, so do not need amplifier.Catadioptre (26) is that the garden is barrel-shaped, and infrarede emitting diode (27) places an end of garden bucket, and the infrared light that sends is the garden cylindricality.

The actuating unit of the present embodiment is identical with the actuating unit of scheme one.

Control circuit as shown in figure 13, it is made up of two eight triple gate, two octal latches, eight schmitt triggers and discriminator (LM567), 4-16 address decoder and 8749 micro controller systems.Two pin of the infrared photo-transistor in the receiver array are connected on respectively on the line and alignment at its place, and when being subjected to infrared radiation, it is with regard to conducting.Each row of array is received on the output pin of address decoder, 16 row, one end is received on the power supply by current-limiting resistance R1, other end separated into two parts, 1～8 row are received each input pin of first triple gate respectively, and 9～16 row are received each input pin of second triple gate respectively.Eight schmitt triggers are received in the output of two triple gates, and then import 3 pin of eight discriminators, the BUS bus of the 8 pin input micro controller system of last eight discriminators.Two triple gates are by 6 lines and 7 line controls of P2 mouth, and when P26 was 1, first triple gate was opened, and P27 is 1 o'clock, and second triple gate opened.P20～P23 is as the input of address decoder.

The input of entire circuit, output are controlled by software, and Figure 14 is this software block diagram, and Figure 15 is the receiver array scanning sequence block diagram in the software.With internal register R5, R4 deposit the initial time headlight about, left and right directions, R1, R0 are the memory address of the pulse encoding table of corresponding stepping motor.Micro controller system is by low 4 output datas of P2 mouth, through address decoder, make a certain behavior low level, then by P26 output high level, first triple gate is opened, if this delegation 1～8 between certain receptor that lists receive signal, list the level that will occur at this so with this signal same frequency, triple gate through opening enters schmitt trigger, import discriminator after the shaping, if the frequency of signal equals the central frequency of discriminator, then 8 pin output low levels of discriminator are sent into the BUS bus, otherwise send into high level.Micro controller system is tested every BUS line, finds out to be that low root, has also just found the row and column of the receptor of receiving signal.If do not occur low level on the BUS bus, first triple gate is closed, second triple gate opened, test every bus again, as still there not being low level, then export the data of P2 mouth again, make next behavior low level of address decoder output, repeat said process, till low level occurring on the BUS bus.

After micro controller system finds the row, column number of this receptor, earlier more current line number and the line number of last time, Figure 16 is the data processor block diagram of micro controller system, according to comparative result, search the pulse encoding table of finishing in advance, output to first latches from the P1 mouth then, the pulse encoding that latchs after amplifying, the stepping motor of drive controlling horizontal direction (13).Micro controller system more current again columns and columns of last time behind output latch, according to comparative result, search the pulse encoding table equally, output to second latches from the P1 mouth then, this pulse encoding after amplifying, the stepping motor of drive controlling pitch orientation (18).When P24 is high, make first latches, and when being low, make second latches through phase inverter F.

More than be according to two embodiments of the principle design that the utility model proposes, also can design other kind embodiment, exemplify no longer one by one here according to this principle.
