Embodiment

As shown in Fig. 1,2,3: this motorcar electric stop sign arm has control box (1), reduction gearing mechanism, pivoted arm (2), annunciator (3), control panel (4) and button; Control box (1) is cube, the motor (6) that is provided with in the control box connects the fork axle (11) of pivoted arm (2) by reduction gearing mechanism, the fork axle (11) of pivoted arm by bearing fixing on control box (1) body, the fixedly connected annunciator of pivoted arm (2) other end (3); Annunciator (3) is an octagon, and the two sides is provided with " stopping " word of the white of the red end of fluorescent paint system.Motor (6) is a direct current electromechanics, connects storage battery and button (5) by control panel (4) by cable (7), and button (5) is contained in the pilothouse, and the fixed head (15) of the external setting of control box (1) is connected on the automobile bodies.

Reduction gearing mechanism is connected with a joggle by worm screw (8) fixing on motor (6) axle and worm gear (9), the worm gear dish is provided with crank (13), crank is connected with connecting rod (12) hinge, and connecting rod is connected with swing arm (14) hinge, the fork axle (11) of the fixedly connected pivoted arm of swing arm (14) other end.

Control panel is electrically connected master control set by starting flip flop equipment, and master control set is controlled motor (6) by photoelectric detection system; Photoelectric detection system is made up of light emitting diode D and phototriode Q2; Photoelectric detection system is arranged on the Photoelectric Detection position L of the worm gear dish corresponding with worm screw (8) top, and the worm gear dish was provided with two the symmetrical holes A1 and the B1 of worm-wheel shaft (10).Its circuit connects the light idol P of start triggering circuit and the controllable silicon S of governor circuit by power supply+12V, and the negative electrode of controllable silicon S connects control motor M, motor M other end ground connection by the field effect transistor Q1 of photoelectric detective circuit; Start triggering circuit connects button A by power supply+12V, the input end of button A and light idol P and resistance R 2 ground connection of connect, and the output terminal of light idol P passes through the trigger end of resistance R 1 connection controllable silicon S; Photoelectric detective circuit is formed by transmitting and receiving circuit, radiating circuit is by resistance R 5 ground connection of connecting with light emitting diode D, and with motor M and connect, receiving circuit connects resistance R 3 by the collector of phototriode Q2, the emitter of triode Q2 connects the base stage of triode Q3, the collector of triode Q3 connects control grid and the resistance R 4 of field effect transistor Q1, triode Q3 grounded emitter.

The installation of this motorcar electric stop sign arm, by four left sides that are bolted to automobile bodies, behind the driver's seat, adjacent vehicle window lower edge part, i.e. the below of first vehicle window lower edge, driver's seat back, the upper edge of stop board is not higher than the vehicle window lower edge; The 12V power lead of umbilical cable (7) connects automobile storage battery, and the control line of umbilical cable (7) is fastened on the control knob (5) in the pilothouse.

During operation, the driver only needs flicking control knob (5) once, and the direct current generator of control casing internal fixation will turn to 90 ° vertical with the compartment by the annunciator stop sign arm that reduction gearing mechanism drives on the pivoted arm from 0 ° parallel with the compartment.The clear word that observably " stops " can both be seen from the vehicle of former and later two direction dealings, slows down or dodges; Ensured children's safety, behind the end-of-job that children get on or off the bus, the driver only needs flicking control knob once, and the stop sign arm will rotate back into 0 ° parallel with the compartment from 90 °, and automobile can cruising.

The transmission of reduction gearing mechanism among Fig. 2, by the worm and wheel engagement that the output shaft of motor is made, the crank on the worm gear dish links to each other with the swing arm hinge by connecting rod; When motor rotated, worm screw drove worm gear and rotates around worm-wheel shaft, and the crank on the worm gear dish is along with making circular motion, the drivening rod translation is swung around output shaft thereby drive swing arm, makes whenever worm gear turns over 180 ° around worm-wheel shaft, be crank when turning over 180 °, swing arm is just in time moved 90 °.The starting point and the terminal point of motion, correspond respectively to stop board parallel with the compartment 0 ° with corresponding to 90 ° vertical of stop board with the compartment; Also corresponding to the A point and the B point of swing arm, so on the worm gear, find corresponding A1 point and B1 point on the diameter line of the line of worm gear axle center and crank, when link motion makes swing arm arrival B point position, the B1 point just in time arrives Photoelectric Detection position L.Worm gear rotates 180 ° then, and the A1 point arrives Photoelectric Detection position L, and A point position is just in time got back in swing arm from the B point along cycloid.

Control circuit adopts the break-make of start triggering circuit control governor circuit among Fig. 3, and governor circuit is controlled motor M by photoelectric detective circuit; Governor circuit is by SCR control, and controllable silicon has the self-sustaining ability, is conducting so click button A controllable silicon, and field effect transistor Q1 is conducting also.The motor M energising is rotated, when the hole that the A1 of worm gear point or B1 are ordered arrives Photoelectric Detection position L, the light that diode D sends makes phototriode Q2 conducting, and then make triode Q3 conducting, result make the control grid shorted to earth of field effect transistor Q1, thereby effect pipe Q1 is ended, the electric current of motor M is reduced to less than silicon controlled keeps electric current, so controllable silicon disconnects, motor M stops operating, and signal stops at the position of 0 ° or 90 °.When clicking button A once more, controllable silicon is conducting once more, and system repeats said process, finally stops at the position 0 ° and 90 °.

Start the triggering loop photoelectricity isolation light idol P has been installed, make the wiring of the silicon controlled control utmost point the shortest, avoid because the misoperation that electromagnetic interference (EMI) causes moves more reliable and more stable.
