Abstract
The utility model relates to a four rotor crafts of folded cascade, including frame, one -level lever apparatus, second grade lever apparatus and drive arrangement, its characterized in that one -level lever apparatus is installed in the frame, and the second grade lever apparatus is installed inside the one -level lever apparatus, and drive arrangement installs the end at the second grade lever apparatus. The one -level lever apparatus includes one -level pole, pin, supporting spring and shop bolt, the second grade lever apparatus includes second grade pole, supporting spring and shop bolt, drive arrangement includes motor cabinet, bolt and nut and motor. When the aircraft was out of work, one -level pole and second grade pole all were in the contraction state, occupy less space, the during operation, and one -level pole and second grade pole all are in development condition, and be mutually similar with the structural morphology of other four rotor crafts. The utility model aims to solve the technical problem that improvement on in the aspect of four rotor craft structure sizes provides a four rotor crafts of folded cascade for four rotor crafts volume under idle state is less, portable.
Description
Technical field
The utility model relates to a kind of aircraft, and or rather, the utility model relates to a kind of folding quadrotor.
Background technology
Quadrotor take off because of it and the requisite space that lands less, handling higher under the intensive environment of obstacle, and the advantage that attitude of flight vehicle hold facility is stronger, therefore rotary aircraft is particularly suitable for the task such as execution monitoring, scouting in environment near the ground, has wide dual-use prospect.In addition, due to rotary aircraft novel in appearance, structure is simple, with low cost, performance is remarkable and it is unique flight mode, rotary aircraft is made to become the focus of research.
When carrying out quadrotor design, the aspect such as lightweight, volume is little, low in energy consumption, cost performance is high be laid particular emphasis on and carry out R & D design.Present quadrotor design much all concentrates on and adopts special material in the weight alleviating aircraft, and in flight control, improve speed and alleviate energy consumption, and seldom operating flexibly with respect to structurally improving to obtain, and the improvement in size.
Summary of the invention
Technical problem to be solved in the utility model be in quadrotor scantling of structure on improvement, a kind of folding quadrotor is provided, makes quadrotor have less volume under out-of-run state, be easy to carry.
A kind of folding quadrotor of the utility model, comprise frame, one-level lever apparatus, secondary lever apparatus and actuating device, it is characterized in that one-level lever apparatus is arranged in frame, it is inner that secondary lever apparatus is arranged on one-level lever apparatus, actuating device is arranged on the end of secondary lever apparatus, described one-level lever apparatus comprises one-level bar, pin, support spring and tommy, above-mentioned one-level bar is by pin and airframe hinge, support spring is arranged in frame location hole of the spring, tommy is arranged in frame location hole of the spring, and be positioned at the both sides of support spring, described secondary lever apparatus comprises secondary bar, support spring and tommy, it is inner that above-mentioned secondary bar is arranged on one-level bar, support spring is arranged in secondary bar location hole of the spring, tommy is arranged in secondary bar location hole of the spring, and be positioned at the both sides of support spring, described actuating device comprises motor cabinet, bolt and nut and motor, above-mentioned motor cabinet is fixedly mounted on secondary bar end by bolt and nut, motor is arranged in motor cabinet.
Utility model works process is as follows: when quadrotor does not work, one-level bar and secondary bar are all in contraction state, now frame location hole of the spring is concentric with one-level bar folded state knock hole, frame location hole of the spring and one-level bar folded state knock hole are positioned by support spring and tommy, one-level bar is made to be in contraction state, secondary bar location hole of the spring is concentric with secondary bar folded state knock hole, secondary bar location hole of the spring and secondary bar folded state knock hole are positioned by support spring and tommy, secondary bar is made to be in contraction state, namely secondary bar is in the inside of one-level bar, when quadrotor works, one-level bar and secondary bar are all in deployed condition, now frame location hole of the spring is concentric with one-level bar deployed condition knock hole, frame location hole of the spring and one-level bar deployed condition knock hole are positioned by support spring and tommy, one-level bar is made to be in deployed condition, secondary bar location hole of the spring is concentric with secondary bar deployed condition knock hole, secondary bar location hole of the spring and secondary bar deployed condition knock hole are positioned by support spring and tommy, secondary bar is made to be in deployed condition, namely secondary bar is extracted out from one-level bar inside.
