Problems solved by technology

However, most of the current multi-axis rotorcraft are skid-type landing gear and multi-legged landing gear. Designed, but the disadvantage is also obvious, it is not convenient to move when on the ground
[0003] Patent CN105270615B has proposed a kind of multi-axis aircraft, adopts wheel type landing gear or skid and wheel type combination structure, compared with skid type landing gear and multi-leg type landing gear, it is convenient to move, but because wheel type landing gear itself does not have The driving device cannot move to the target position autonomously, and must be moved with the support of the staff
[0004] With the rapid development of AI technology and the continuous improvement of the degree of unmanned operation, the unmanned and autonomous operation of multi-axis rotor aircraft will also be an inevitable trend. However, the current multi-axis rotor aircraft platform obviously cannot meet the intelligence of unmanned autonomous operation Therefore, it is necessary to develop a multi-axis rotorcraft with powered wheeled landing gear

Embodiment 1

[0078] Such as Figure 1 to Figure 3 As shown, the present embodiment provides a multi-axis rotorcraft with a powered wheeled landing gear, including a body 10 , a support rod 20 , a multi-axis rotor system 30 and a wheeled landing gear system 40 .

[0079] Airframe 10 is arranged in the middle of the aircraft and includes equipment compartment 11 , payload compartment 12 , equipment support 13 , load-bearing frame 14 , shell 15 and equipment 16 . The equipment 16 includes a power supply system, a control system, communication equipment, sensors and the like. The equipment compartment 11 is arranged at the front and the rear of the body 10 to provide space for the equipment 16; the payload compartment 12 is arranged in the middle of the body 10 to provide space for payload or personnel; the equipment support 13 is arranged inside the equipment compartment 11, and The load-bearing frame 14 is fixedly connected to provide installation space for the equipment 16; the load-bearin...

Embodiment 2

[0084] Such as Figure 4 to Figure 7 As shown, on the basis of Embodiment 1, this embodiment moves the equipment compartment 11 between the front and rear supports 20 to reduce the volume of the payload compartment 12; at the same time, the support rod 20 and the propeller 32 are changed into a foldable form, so that Reduce the overall size of the aircraft in the ground parking state or storage state, reduce the parking area of ​​the aircraft, and improve the portability of the aircraft transportation.

[0085] Specifically, landing gear struts 42 are respectively arranged on the left and right sides of the rear of the body 10. The landing gear struts 42 are designed in one piece, and the landing gear struts 42 are fixedly installed on the bottom of the body 10. , is connected with the wheel 41 through the driving motor 43, and the driving motor 43 is a radial motor or an axial motor.

[0086] The support rod 20 is a split structure, and there are two support rods 20. Each su...

Embodiment 3

[0089] Such as Figure 8 to Figure 10 As shown, on the basis of the first embodiment, this embodiment optimizes the layout of the middle support rod 21, and adds a support rod adapter 24, and then combines the foldable support rod 20 and the foldable propeller 32 described in the second embodiment, in the While reducing the overall size of the aircraft, it has a more streamlined shape and reduces flight resistance.

[0090] Specifically, the support rod 20 is a split structure, and the support rod 20 includes a middle support rod 21, an end support rod 22, a foldable connector 23, and a support rod adapter 24. There are at least four middle support rods 21, and the payload compartment is arranged. 12, the front, rear and both sides, and the two adjacent middle support rods 21 are fixedly connected at the ends; one end of the support rod adapter 24 is fixedly connected with the joints of the two adjacent middle support rods 21, and the other end is horizontal It protrudes obli...

Abstract

The invention relates to the technical field of aircrafts, and discloses a multi-shaft rotor aircraft with a power wheel type undercarriage. The aircraft comprises an aircraft body, a number of supporting rods which are arranged around the aircraft body and connected with the aircraft body, a number of multi-shaft rotor systems which are arranged at the ends, away from the aircraft body, of the corresponding supporting rods correspondingly and used for providing power and control torque for taking off and landing, and a wheel type undercarriage system which is arranged on the lower portion of the aircraft body and connected with the aircraft body, and the wheel type undercarriage system is provided with a driving device and used for providing ground movement power for the aircraft. The multi-shaft rotor aircraft with the power wheel type undercarriage not only can freely fly in the air like a common multi-shaft rotor aircraft, but also can freely move on the ground like a robot.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a multi-rotor aircraft with power wheel landing gear. Background technique [0002] At present, multi-axis rotorcraft is developing rapidly, and has achieved large-scale applications in agricultural plant protection, logistics transportation, patrol, inspection, etc., and the application effect is remarkable. However, most of the current multi-axis rotorcraft are skid-type landing gear and multi-legged landing gear. Designed, but the disadvantage is also obvious, it is not convenient to move when it is on the ground. [0003] Patent CN105270615B has proposed a kind of multi-axis aircraft, adopts wheel type landing gear or skid and wheel type combination structure, compared with skid type landing gear and multi-leg type landing gear, it is convenient to move, but because wheel type landing gear itself does not have The driving device cannot move to the target position autonomou...
