Bottom near one end of flexible paddle arm 122 offers escape groove.Escape groove is used to prevent from fixing paddle arm 121 to touch with motor
Hit.Therefore, the escape groove that paddle arm 122 of stretching is opened up equally can avoid fixing interfering between paddle arm 121 and motor.
When the length long enough of tooth bar 124, and motor 19 the fixed paddle arm 121 of installation site distance it is remote enough when, fixing oar
Arm 121 and flexible paddle arm 122 are without the need for Chong Die, you can meet the regulation of the brachium of scalable paddle arm component 12, then escape groove can be with
Omit.It is appreciated that winding mechanism 18 can also be fixed at the inside of flexible paddle arm 122.Stretch because motor 19 is located at
In contracting paddle arm 122, motor 19 is electrically connected by winding mechanism 18 with second source and the second pcb board.Then winding mechanism 18
Can be also used for the wire between the wire or the pcb board of motor 19 and second between folding and unfolding motor 19 and second source
20.Then winding mechanism 18 is provided with two spools, then winding mechanism 18 is respectively to the wire 20 of power motor 16 and motor 19
Carry out folding and unfolding.
In above-mentioned unmanned plane 10, fixed paddle arm 121 passes through the company of being driven of 123 tooth bar of gear 124 with flexible paddle arm 122
Connect, by rotate gear 123, tooth bar 124 is moved under the driving of gear 123.Therefore, gear 123 is rotated and reverse, tooth bar
124 it is relative advance or retreat, so as to drive it is close to each other between flexible paddle arm 122 and fixed paddle arm 121 or away from.Therefore, on
Stating the paddle arm length of unmanned plane 10 can be adjusted by the tooth bar 124 of gear 123.
When scalable paddle arm component 12 opens, it is possible to increase positioned at multiple tops of flexible paddle arm 122 propeller 17 point
Cloth distance, and then can be the propeller 17 that unmanned plane 10 matches different size, imitated to meet different answering with forming different power
Use demand.When collocation large scale propeller 17, the power effect of propeller 17 can be improved, and then improve the whole machine effect of unmanned plane 10
Rate, increases the cruising time of unmanned plane 10.
When scalable paddle arm component 12 is retracted, the volume of unmanned plane 10 reduces, and the unmanned plane 10 is applied to heavy burden
Relatively low situation.Now the scalable paddle arm component 12 of unmanned plane 10 can arrange in pairs or groups undersized propeller 17, can improve nobody
The motility of machine 10.Also, when needing that unmanned plane 10 is carried or deposited, make the scalable paddle arm of unmanned plane 10
Component 12 shrinks, and is easy to the placement of unmanned plane 10 and carries.
