Description
One, technical field
The utility model relates to a kind of operating mechanism, and particularly a kind of model copter rotor control mechanism is applied on the model copter.
Two, background technology
The main rotor of model copter also will be according to the angle of attack of the needs periodic variation rotor of flight when producing lift, thus the flight attitude of control helicopter.Common model copter has adopted cross pitch, ball head connecting rod, lever, stabilizer to drive complicated transmission mechanisms such as rotor in order to reach the cyclomorphosis rotor angle of attack, use 2 steering wheels to handle the pitching and the inclination of helicopter.Because the transmission mechanism link is many, the gap of each junction directly influences the accurate handling quality of helicopter.Complicated simultaneously agency cost height damages easily, adjusts difficulty.
Three, summary of the invention
The purpose of this utility model provides the model copter operating mechanism that a kind of maneuvering performance is good, simple in structure, cost is low.
Model copter rotor control mechanism of the present utility model, comprise frame, rotor shaft, bearing, rotor head, rotor, it is characterized in that it also comprise integral body be enclosed within rotor shaft by fixed magnetic pole, connect together with fixed magnetic pole and be fixed on magnetic conduction sheet on the frame, have shoulder hole and shoulder hole minor diameter one end and tightly overlapping the coil rack that has coil of fixed magnetic pole, cover on the ring electromagnet of outer magnetism-guiding hood of coil rack and the detachable pole composition that is in coil rack shoulder hole major diameter one end, be contained in the photoelectricity phase detector on the magnetism-guiding hood, with the close-connected plastics sliding sleeve of detachable pole and be located at anti-dazzling screen on the plastics sliding sleeve; Rotor shaft is a multidiameter, and the following shaft shoulder is bearing on the bearing inner ring, and the last shaft shoulder is higher than fixed magnetic pole; The rotor shaft upper end is with propeller boss; The plastics sliding sleeve is connected by keyway with propeller boss; Boss one side of plastics sliding sleeve is connected with rotor head by ball head connecting rod, and opposite side is connected with propeller boss by extension spring.
The diameter of detachable pole determined by the size of model copter, usually its to select scope for use be 5-50mm.
Model copter rotor control mechanism of the present utility model, detachable pole is undertaken spacing by the last shaft shoulder of propeller boss and rotor shaft, can slide up and down and rotate with propeller boss in rotor shaft, drives rotor by ball head connecting rod and changes the angle of attack.Change just can be handled the pitching and the inclination of model copter to the power supply phase place and the duration of electromagnet.
Model copter rotor control mechanism of the present utility model has characteristics simple in structure, that cost is low, and its maneuvering performance is good, and is not fragile.
Four, description of drawings
Accompanying drawing is a model copter rotor control mechanism structural representation of the present utility model.
Five, the specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing, model copter rotor control mechanism of the present utility model comprises frame 14, rotor shaft 12, bearing 11, rotor head 1, rotor 2.It also comprise integral body be enclosed within rotor shaft 12 by fixed magnetic pole 13, connect together with fixed magnetic pole 13 and be fixed on magnetic conduction sheet 10 on the frame 14, have shoulder hole and shoulder hole minor diameter one end and tightly overlapping the coil rack that has coil 87 of fixed magnetic pole 13, cover on the outer magnetism-guiding hood 9 of coil rack 7 and be in the ring electromagnet that the detachable pole 6 of coil rack 7 shoulder hole major diameters one end is formed; Be contained in the photoelectricity phase detector 15 on the magnetism-guiding hood 9; With detachable pole 6 close-connected plastics sliding sleeves 4 and be located at anti-dazzling screen 5 on the plastics sliding sleeve 4.Rotor shaft 12 is multidiameters, and on the following shaft shoulder was bearing in and encircles in the bearing 11, the last shaft shoulder was higher than fixed magnetic pole 13, and detachable pole 6 also can not contacted with fixed magnetic pole 13 when upper/lower positions.Rotor shaft 12 upper ends are with propeller boss 16.Plastics sliding sleeve 4 and propeller boss 16 are connected by keyway.Boss one side of plastics sliding sleeve 4 is connected with rotor head by ball head connecting rod, and opposite side is connected with propeller boss by extension spring.Detachable pole 6 is a tight fit with plastics sliding sleeve 4, and detachable pole 6 and plastics sliding sleeve 4 can slide up and down along rotor shaft 12 like this, and along with propeller boss 16 rotates together.Detachable pole 6 was not in the extreme higher position when coil 8 was switched under the effect of extension spring 3.Coil 8 energising back detachable poles 6 move down, and the angle of attack of rotor 2 increases, and another corresponding rotor angle of attack reduces.Rotor shaft 12 whenever rotates a circle, and anti-dazzling screen 5 enters photoelectricity phase detector 15 once.Control circuit (not drawing on the figure) is powered to coil 8 in the different moment (phase place) according to the control signal of this phase signal and remote controller output, and rotor 2 will begin to change the angle of attack in appointed positions like this.The power-on time length of regulating winding 8 just can change the position that rotor 2 angles of attack recover.
The following shaft shoulder of rotor shaft 12 is bearing on the interior ring of bearing 11 among the embodiment.The last shaft shoulder of rotor shaft 12 is than the high 0.3-0.5mm of height of fixed magnetic pole 13.The lower portion of coil rack 7 and fixed magnetic pole 13 are tight interference fits, and fixed magnetic pole 13 is connected as a single entity with magnetic conduction sheet 10.The perforate of the first half of coil rack 7 and magnetism-guiding hood 9 is than the big 0.8-1mm of diameter of detachable pole 6.It is 0.8-1mm that the height of adjusting propeller boss 16 lower edges makes the stroke of detachable pole 6, like this at the distance of shaft centers of the center line of ball head connecting rod 17 and rotor head 1 when being 10mm, the variable quantity of rotor 2 angles of attack is 5 °.Adjust the length of connecting rod 17, make the angle of attack unanimity of detachable pole 62 slurries of rotor when uppermost position in fig-ure.
Change because rotor 2 angles of attack can only be great-jump-forwards, realize different manipulated variables, can pass through to adjust the length of coil 8 power-on times, but the longest power-on time can not be greater than 1/2 of rotor 2 rotation periods.
