Description

Ultrasonic wave controlling multifunction electric-toy car

The utility model belongs to the electronic toy class, relates to a kind of multifunction electronic toy car of ultrasonic wave control.

Existing voice-control toy automobile mainly is to driving wheel---the rotation of trailing wheel and stop to carry out sound control, to the then not control of front-wheel that turns to, so this toy car can only be controlled it and keep straight on forward or fall back backward, can not about turn round, more do not imitate the turning indication of real car.The automobile that has has been opened arc groove on the chassis, make the front-wheel might be to a direction deflection, thereby toy car is turned, but this is random, non-controlled.

The purpose of this utility model provides a kind of electronic toy automobile that turns to and send corresponding sound, light indication about it of controlling with ultrasonic wave.

The utility model includes casing, chassis and drive motors.Can send the acousto-optic indicating circuit of corresponding sound and light signal and the ultrasonic wave control circuit of control steer motor when it is characterized in that having the steering mechanism that promotes by steer motor to turn.If ultrasonic wave enters the ultrasonic wave control circuit, then this circuit is exported a switching signal and steer motor work loop is connected.Steer motor starts the back and promotes steering mechanism's motion, and toy car is kept straight on or to moving ahead or left and right turning or parking, and when turning, send mutually at the sound, light indicates.

The utility model control circuit and steering mechanism are simple, easy to implement, and control action is more.Emulation is strong, can give the inspiration of child with scientific common sense.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the steering box composition;

Fig. 2 is sound, light indication and drives the control principle circuit diagram;

Fig. 3 is a ultrasonic wave control principle circuit diagram.

Among Fig. 1,1 is steer motor, and 2 is worm screw, and 3 is worm gear, and 4 is bearing pin, and 5 is T type rigid bar, 6 and 6 ' for leading arm, 7 and 7 ' be front-wheel, 8 is left stationary contact, and 9 right sides are stationary contact, and 10 is the movable contact (cutter) of commutator.11 is the rotating shaft of worm gear 3.T type rigid bar 5 and lead arm 6 and 6 ' formation steering link wherein.Constitute steering mechanism by steer motor 1, worm screw 2, worm gear 3, bearing pin 4 and steering link.After steer motor was rotated, it drove with its coaxial worm 2 and rotates, and worm screw 2 drives the worm gear 3 that is meshed with it and rotates, and the protruding bearing pin 4 on the worm gear 3 just drives steering link.The longitudinal rod of T type rigid bar 5 is bars that there is open slot a centre, so that the bearing pin 4 of projection passes from open slot, the width of groove is slightly larger than the diameter of bearing pin 4, its length approximates the diameter of worm gear 3, so that worm gear 3 rotates a circle, can make bearing pin 4 drive T type rigid bar 5 and do translation to the left or to the right.Worm gear 3, bearing pin 4 are mutual insulatings with T type rigid bar 5.Arm 6 and 6 ' be hinged is led with two respectively in the two ends of T type rigid bar 5, lead arm 6 and 6 ' the other end be connected with the chassis by screw and can rotate around the chassis, like this, when T type rigid bar 5 is done left and right translation, just can be driven and lead arm and swing to the left or to the right.Because two front-wheels 7 and 7 ' and lead arm 6 and 6 ' an end by spool being connected, two axles with lead arm and be and fixedly connected.Two front-wheels all can rotate around the axis.Owing to adopt above-mentioned measure, lead the left and right swing of arm and just can make that front-wheel is left and right to be turned to.The translatory distance of T type rigid bar 5 is directly proportional with the front-wheel steer angle.Worm gear adopts the metallic plate of conduction to make, worm gear on the plate face on chassis with bearing pin 4 end in opposite directions, establish an insulation layer N.

In Fig. 2, be connected with an end of elasticity phosphorus bronze sheet 12 and that plate face that contains insulation layer N of worm gear 3, the other end is connected to the negative pole of power supply E2.Drive motors M2 one is terminated at power supply E2 positive pole, and the other end is connected to the rotating shaft 11 of worm gear 3, and rotating shaft 11 is conductive and mutual connections with worm gear 3.Load onto battery connection power supply E2 and just make drive motors M2 form the loop, drive motors rotates, and toy car obtains driving force and travels.Have only when worm gear and rotate to phosphorus bronze sheet 12 when contacting, drive motors loop open circuit, motor stall this moment, parking of automobile with insulation layer N.The negative pole of power supply E2 also with lead arm 6 on commutator cutter---movable contact 10 links to each other, when leading arm 6 swings, movable contact 10 can contact with

stationary contact

8 or 9 respectively, and each stationary contact all is connected to the positive pole of power supply E2 by a resistance, a light emitting diode, two audio oscillator circuit VF respectively in parallel between the positive pole of light emitting diode and stationary contact, when automobile was kept straight on, the movable contact 10 of leading on the arm 6 mediated, sound, light indicating circuit open circuit, noiseless, light indication.When automobile was turned to the left or to the right, the cutter 10 of leading on the arm 6 band commutators rotated, and movable contact 10 and stationary contact 8 are connected, and promptly automobile is turned left, connects left side leds and the concurrent bright dipping of audio oscillator circuit, sound indication; If movable contact 10 is connected with stationary contact 9, then automobile bends to right, and connects right side light emitting diode and audio oscillator circuit, sends light, sound indication.

W is that electret is encouraged sound head among Fig. 3, is used to receive acoustic signals, and T1, T2, T3, T4, T5 are transistor, and M1 is a steer motor, and C1 is a high-frequency coupling electric capacity, so that ultrasonic signal can be coupled to the base stage of T1, and audio signal is play by effect.C is a delay capacitor.The characteristics of this circuit are to receive ultrasonic wave work.When no ultrasonic control signal entered, T1, T2, T3 transistor all were in the amplification attitude, and Darlington transistor T4, T5 end, and no current passes through in the motor M 1, and M1 does not change; When having control signal to enter, T1, T2, T3 are still for amplifying attitude, T4, T5 conducting, electric current constitutes the loop through motor M 1 and T4, T5, electronic rotation, simultaneously electric current charges to capacitor C, and just Darlington transistor T4 and T5 prolong ON time because of the discharge of capacitor C, worm gear 3 is rotated to an angle, the automobile turning segment distance that travels.

Press E1=E2=3V, W selects for use the electret of CR22-15 to encourage sound head, and C=2.2 μ F and T1～T3 select β=60～80, and T4, T5 select β=80～100, have implemented the utility model.When recording no signal, Fig. 3 current sinking is 3 milliamperes, and motor terminal voltage is 0.02V, have the signal motor to rotate after, total power consumption is 80 milliamperes, motor terminal voltage is 2 volts.When if the speed ratio of worm gear and worm screw is 1:40, ultrasonic signal of the every reception of circuit, worm gear 3 rotated for 1/4 week approximately, can realize keeping straight on forward, turn and stop about forward, and when turning, send mutually at the sound, the light index signal.This device ultrasonic wave control signal is the higher hamonic wave that adopts in the audio signal.
