Description
Technical field
The utility model belongs to the technical field of RC Goblin, is specifically related to a kind of pitch control structure that is applied to RC Goblins such as toy helicopter or model helicopter.
Background technology
The advancing of RC Goblin, retreat, left and right sides flies to realize through the control pitch.Pitch is the fuselage active tilt relatively; It comprises rotating ring and rotating ring not, rotating ring and do not form relatively turnable socket between the rotating ring, and rotating ring is related to propeller blade through vertical link; Rotating ring and propeller blade rotate synchronously during flight, and rotating ring does not then rotate.When promoting pitch "Left"-deviationist or Right deviation, then rotating ring "Left"-deviationist or Right deviation make the corresponding inclination in screw blade face, thereby produce cross component force (being the power that side flies) to the left or to the right; In like manner, lean forward or hypsokinesis when promoting pitch, then rotating ring makes the corresponding inclination in screw blade face, thereby produces component (being the power of forward-reverse) forward or backward.
In the existing RC Goblin, pitch utilizes universal bearing to be installed on the rotor shaft, realizes thus tilting to all directions; The not rotating ring of pitch directly is connected with two main ties, and these two main ties are connected with actuating unit respectively, and wherein first main tie is responsible for promoting that pitch leans forward or hypsokinesis, and second main tie is responsible for promoting pitch "Left"-deviationist or Right deviation.
But there is following shortcoming in the said structure form: 1, universal bearing has a plurality of frees degree, when controlling that first main tie promotes that pitch leans forward or during hypsokinesis, owing to reasons such as machine errors; Often also can make unexpected "Left"-deviationist or the Right deviation that produces to a certain degree of pitch, vice versa, when controlling second main tie promotion pitch "Left"-deviationist or Right deviation; Owing to reasons such as machine errors; Often can make pitch produce leaning forward or hypsokinesis to a certain degree, it is not accurate that heading is controlled yet, and promptly flies in the journey controlling the toy helicopter side; Can occur flying before the accident to a certain degree or retreating; Equally, before controlling toy helicopter, fly or fallback procedures in, the unexpected side that also can occur to a certain degree flies.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcoming and a kind of RC Goblin pitch control structure is provided, and it can accurately control heading.
Its purpose can realize by following scheme: this RC Goblin pitch control structure comprises fuselage, screw assembly, rotor shaft; The pitch of fuselage active tilt relatively also is installed on fuselage, and pitch comprises rotating ring and rotating ring not, rotating ring and not rotating ring form relatively turnable socket; Its main feature is; Also be provided with the pitch support, the pitch support is provided with first horizontal rotating shaft, and first horizontal rotating shaft is installed in body upper; The pitch support can rotate around first horizontal rotating shaft, and the bearing of trend of first horizontal rotating shaft is fore-and-aft direction or left and right directions; The not rotating ring of pitch is provided with second rotating shaft, and second rotating shaft is vertical with the first horizontal rotating shaft antarafacial, and second rotating shaft is installed on the pitch support, and whole pitch can rotate around second rotating shaft; The pitch support is connected with first main tie, and the not rotating ring of pitch is connected with second main tie, and first main tie is connected with first driving mechanism, and second main tie is connected with second driving mechanism.
The utlity model has following advantage and effect:
1, the pitch of the utility model does not adopt traditional universal bearing mounting structure; But the rotating shaft (i.e. the not rotating shaft of rotating ring) of pitch is installed on the pitch support; And the rotating shaft of pitch is vertical with the rotating shaft antarafacial of pitch support; Pitch is spurred by different main ties respectively with the pitch support, like this, and when the vertical pulling of first driving mechanism first main tie; Then driving the pitch support rotates around first horizontal rotating shaft; Pitch also rotates around first horizontal rotating shaft thereupon, makes pitch pure leaning forward or hypsokinesis (when the bearing of trend of first horizontal rotating shaft is left and right directions) occur, pure "Left"-deviationist or Right deviation (when the bearing of trend of first horizontal rotating shaft is fore-and-aft direction) perhaps occur; When the vertical pulling of second driving mechanism second main tie; Then the pitch support is motionless; And pitch rotates around second rotating shaft; Make pitch pure leaning forward or hypsokinesis (when the bearing of trend of second rotating shaft is left and right directions) occur, pure "Left"-deviationist or Right deviation (when the bearing of trend of second rotating shaft is fore-and-aft direction) perhaps occur.Like this, avoided flying in the journey and occurring flying or retreat phenomenon before unexpected controlling the toy helicopter side, same, also can avoid before controlling toy helicopter, flying or fallback procedures in unexpected side occurs and fly phenomenon.

The specific embodiment
Embodiment one
Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5; This RC Goblin pitch control structure comprises fuselage 1, screw assembly 2, rotor shaft 3, and the pitch of fuselage active tilt relatively also is installed on fuselage 1, and pitch comprises rotating ring 44 and rotating ring 45 not; Rotating ring 44 and the not relatively turnable socket of rotating ring 45 formation; Also be provided with pitch support 5, pitch support 5 is provided with first horizontal rotating shaft 51, and pitch support 5 can rotate around first horizontal rotating shaft 51; First horizontal rotating shaft 51 is installed in body upper, and the bearing of trend of first horizontal rotating shaft 51 is a left and right directions; It is vertical with first horizontal rotating shaft, 51 antarafacials that the not rotating ring of pitch is provided with second rotating shaft, 41, the second rotating shafts 41, and second rotating shaft 41 is extended along fore-and-aft direction, and second rotating shaft 41 is installed on the pitch support, and whole pitch can rotate around second rotating shaft 41; Pitch support 5 is connected with first main tie 52, and the not rotating ring 45 of pitch is connected with second main tie, 42, the first main ties 52 and is connected with first driving mechanism, 53, the second main ties 42 and is connected with second driving mechanism 43.
