Abstract
The present invention relates to a kind of damping undercarriage of four-axle aircraft, belonging to one kind has shock-absorbing function unmanned plane undercarriage.Motor is fixed using support, motor is driven in different directions by one group of gear driven, two sections of belts, then by the receipts of belt drive undercarriage, undercarriage is hinged with connected device, and upper end is connected by extension spring, and undercarriage is divided into upper and lower two-arm, connected by crossbeam, built-in spring.Advantage is novel structure, and undercarriage can carry out folding and unfolding, reduce the resistance of air in flight course according to state of flight, substantially increase the stability of unmanned plane.In descent, undercarriage is scalable, reduces shock loading coefficient, improves the security of unmanned plane.
Description
Technical field
There is shock-absorbing function unmanned plane undercarriage the invention belongs to one kind, and in particular to have rising for freedom retractable and Telescopic
Fall frame, be mainly used in flight course reduce resistance and decline during slow down in face of fuselage impulsive force.
Background technology
Four rotor wing unmanned aerial vehicles are a kind of Small and micro-satellites, and because flexibility ratio is high, stability is strong, and simple to operate, cost is relatively low
Gained great popularity etc. advantage.But, four current rotor wing unmanned aerial vehicles, in the air because its undercarriage fixed increases resistance during flight
Greatly, in addition, very strong rigid shock can be caused in face of fuselage in landing, and in this regard, four rotor wing unmanned aerial vehicles still face very
Big challenge.
The content of the invention
The present invention provides a kind of damping undercarriage of four-axle aircraft, to solve the flight that current Small and micro-satellite is present
The problem of rigid shock when resistance and landing.
The present invention is adopted the technical scheme that：Motor in for connecting the support of unmanned plane, gear one and motor
Output shaft is connected, and gear two is connected by axle with holder pivots, and gear one is connected with the engagement of gear two, and tooth form drive one is fixed
It is connected on the output shaft between gear one and motor, tooth form drive two is fixedly connected between gear and support, tooth form is passed
Driving wheel one is connected with odontoid belt one, and tooth form drive two is connected with odontoid belt two, and odontoid belt one, odontoid belt two are another
Tooth form drive of the side respectively with two undercarriage upper arm is connected, wherein undercarriage upper arm and connected device chain connection, undercarriage
Extension spring is connected between upper arm and connected device, undercarriage upper arm enters the cunning of undercarriage upper arm with undercarriage underarm by crossbeam-rotating
Fixation after groove, and built-in spring respectively, the connector being connected with fuselage are connected with connected device.
It is an advantage of the invention that structure is novel, undercarriage can carry out folding and unfolding according to state of flight, in reducing flight course
The resistance of air, substantially increases the stability of unmanned plane.In descent, undercarriage is scalable, reduces shock loading
Coefficient, improves the security of unmanned plane.

Specific embodiment
Motor 2 is mounted in in the support 1 for connecting unmanned plane, gear 1 to be connected with the output shaft of motor 2, and gear 24 leads to
Cross axle to be connected with holder pivots, the engagement of gear 1 and gear 24 be connected, tooth form drive 1 be fixedly connected on gear 1 and
On output shaft between motor 2, tooth form drive 26 is fixedly connected between gear 4 and support 2, tooth form drive 1 and tooth
Shape belt 1 is connected, and tooth form drive 26 is connected with odontoid belt 28, odontoid belt one, the opposite side of odontoid belt two difference
Tooth form drive 9 with two undercarriage upper arm 12 is connected, wherein undercarriage upper arm 12 and connected device chain connection, on undercarriage
Extension spring is connected between arm 12 and connected device, undercarriage upper arm 12 is rotated on undercarriage with undercarriage underarm 13 by crossbeam 11
Fixation after the chute 10 of arm 12, and built-in spring 14 respectively, the connector being connected with fuselage are connected with connected device.
Operation principle：During unmanned plane during flying, by controlling the rotation of stepper motor 2, band moving gear 1 and tooth form
Drive 1 is rotated, and power is reached on belt 1, and gear 1 drives driven gear 24 to rotate, and power is passed into tooth form passes
Driving wheel 26, tooth form drive 26 reaches on belt 28 power；Belt 27, belt 28 drive undercarriage upper arm 12 respectively
Tooth form drive 9 rotate, the folding and unfolding for driving undercarriage overall connects extension spring, in step between undercarriage upper arm 12 and connected device
When stepper motor 2 runs out of steam, undercarriage can in time be retracted initial position, undercarriage upper arm 12 and the phase of undercarriage underarm 13
Even, when ground is drop to, the compression spring 14 of undercarriage underarm 13 plays a part of damping to built-in spring 14.
