Description
Technical field: novel practicality relates to a kind of wireless remotely-controlled model of an airplane, is specially the small-sized helm gear of the wireless remotely-controlled model of an airplane in automatically returning.
Background technology: the present wireless remote control model of an airplane, great majority all adopt the proportion expression steering wheel, though this steering wheel can finish proportional control aeromodelling airplane rudder face, but complex structure, and need one to overlap complicated ratio circuit, event is the cost height not only, also more about 8 grammes per square metres of steering wheel weight, to the microlight-type remote controlled model airplane, still weight is too big, though I am little at time kind of the steering wheel volume automatically of application utility model patent remote-controlled model aircraft in 1998, have only 3 grammes per square metres, see that application number is that " 98208391.2 " name is called " remote-controlled model aircraft automatically return kind of a steering wheel " and also has two problem and shortage, 1, the steering wheel complex structure is shared 9 gears, 2, can not directly drive rudder face, also need the grade connect mechanism of more complicated of rudder face connecting rod and adjusting portion.
Summary of the invention: the purpose of this utility model is to provide a kind of simple in structure, with low cost, easy for operation, control is stable in returning automatically small-sized helm gear.The purpose of this utility model is achieved in that it comprises direction stabilization (1), axle hinge (2), rudder (3), guide groove (4), guide rod (5), steering wheel shell (6), returns median septum (7), spacing dividing plate (8), limited post (9), gear wheel (10), motor (11), pinion (12), spring leaf (13), Large Gear Shaft During (14), constant-current source (15).Axle hinge (2) one ends are connected with direction stabilization (1), the other end is connected with rudder (3), guide rod (5) is connected with Large Gear Shaft During (14), two spring leafs (13) go back to median septum (7) both sides with fork-shaped through what the main shaft of motor (11) and Large Gear Shaft During (14) abutted against gear wheel (10), make rudder (3) with return median septum (7) keep synchronously, have back above gear wheel (10) one sides spacing dividing plate (8) is arranged below median septum (7), the side, reach about two limited posts (9).The utility model has the advantages that: simple in structure, with low cost, easy for operation, volume is little, in light weight.
Description of drawings: Fig. 1 is the utility model structural principle schematic diagram; Fig. 2 is this practical circuit structure principle schematic.
The specific embodiment: axle hinge (2) one ends are connected with direction stabilization (1), the other end is connected with rudder (3), guide rod (5) is connected with Large Gear Shaft During (14), two spring leafs (13) go back to median septum (7) both sides with fork-shaped through what the main shaft of motor (11) and Large Gear Shaft During (14) abutted against gear wheel (10), make rudder (3) with return median septum (7) keep synchronously, have back above gear wheel (10) one sides spacing dividing plate (8) is arranged below median septum (7), the side, reach about two limited posts (9).The utility model operation principle: be divided into into three parts: first directly drives the rudder face part: be by the direction stabilization, and the stable over glaze hinge of direction, closure rudder, rudder lower end have guide groove to be connected with guide rod.Second portion is that the machine of rudder is guarded against part: be by shell (6), motor, pinion (12), drive that gear wheel, Large Gear Shaft During upper end are equipped with guide groove and guide rod, median septum is arranged back above gear wheel one side, two flat springs in returning with fork-shaped by motor main shaft and Large Gear Shaft During arrival and abut against the dividing plate both sides of gear wheel, make the rudder face of steering wheel remain at the centre position, have below gear wheel one side spacing dividing plate, and about two limited posts.Third part is to supply with the power unit of steering gear electric-machine, has taked two constant-current sources, and its effect is exactly to guarantee the motor of steering wheel operating current when rotated and blocking-up electric current, electric current is limited in the scope of design, to guarantee the safety and the operate as normal of motor.
Guide rod inserts in the guide groove operation principle of the small-sized steering wheel of moving rudder face of direct generation: control the rotating of steering wheel after the different signal of two-way is imported in the different time respectively respectively, finishing rudder face rotates to the left or to the right, wherein one road signal regulation steering gear electric-machine is when just changeing, the pinion of installing on the motor shaft drives gear wheel and turns left, central dividing plate above when gear wheel turns left also moves thereupon, pushed the spring leaf that leans against the left side open, dividing plate below gear wheel also turns left, stopped rotation during to the left side limiting stand, this moment, steering gear electric-machine also stopped rotation, the guide rod or the guide groove of the rudder face of the upper end one side guide rod of Large Gear Shaft During or guide groove drive at this moment make rudder put in place towards left-hand rotation, but motor still has the electric current mistake, and being subjected to constant-current source is limited to electric current in the scope of setting, make motor continue the power of rotating and refuse, the existence that rotatory force is refused makes gear wheel continue to abut against the left side limiting stand.In the time of the main story blackout, the motor of steering wheel does not have electric current to flow through, and rotatory force refuses to disappear, and this moment, the gear wheel near the left side utilized the elastic force of the left side spring of dividing plate that gear wheel is pushed back original centre position, promptly drives during rudder face returns automatically.
When another road signal regulation steering gear electric-machine is counter-rotating, the pinion moving gear wheel of installing on the motor shaft of generation turns right, central dividing plate above when gear wheel turns right also moves thereupon, pushed the spring leaf that leans against the right side open, dividing plate below gear wheel also turns right, stopped rotation during to the right side limiting stand, this moment, steering gear electric-machine also stopped rotation, the guide rod or the guide groove of the rudder face of the upper end one side guide rod of Large Gear Shaft During or guide groove drive at this moment make rudder put in place towards right-hand rotation, but motor still has the electric current mistake, and being subjected to constant-current source is limited to electric current in the scope of setting, make motor continue the power of rotating and refuse, the existence that rotatory force is refused makes gear wheel continue to abut against the right side limiting stand.In the time of the main story blackout, the motor of steering wheel does not have electric current to flow through, and rotatory force refuses to disappear, and the gear wheel that keep right this moment utilizes the elastic force of the left side spring of dividing plate that gear wheel is pushed back original centre position, promptly drives during rudder face returns automatically.
