Problems solved by technology

[0004] After the center of gravity of the UAV shifts, it will make it difficult for the UAV to fly normally and smoothly, and even cause the UAV to crash
Especially for multi-blade UAVs, when the center of gravity is seriously shifted, the motor on the side near the center of gravity is likely to increase due to the load of the motor ESC, which will affect the normal operation of the UAV.

Embodiment 1

[0041] figure 1 The structure of the drone provided by the embodiment of the present invention, such as figure 1 As shown, this embodiment provides a drone, which can be applied to border defense patrol, aviation imaging, distribution distribution, construction site surveying, agricultural plant protection, manned flight, etc., this embodiment does not perform specific application scenarios for drones. limit. Further, the present embodiment will be specified as an example of a manned drone as an example, but it can be understood that the drone provided by the present invention can also be a non-carrier-type drone.

[0042] Specifically, the drone includes a body 3, a rotor 2, a flying control system, a center of gravity flattening means 1, and a landing gear 4, and the like. The body 3 is made of metal material, providing support and protection for the entire drone, and the body 3 is configured along its longitudinal centerline to ensure the stability of the drone structure; the ...

Embodiment 2

[0061] This embodiment provides a center of graft method of drone and drone, and the basic structure of the drone provided in the present embodiment is identical, only rotor 2 and flying control only. There is a difference in the setting of the system, and the present embodiment is no longer described in the same structure as the embodiment.

[0062] In the present embodiment, the rotor 2 is only provided with a set, and the rotation center axis of the rotor 2 passes through the center of gravity of the drone itself. The drive control unit includes a steering machine, and a steering machine is provided with a plurality of, configured to control the cycle pitch of the propeller in the rotoruk 2 to regulate the flight posture of the drone.

[0063] Setting of single rotorial drones is a conventional setting in the art, and the present embodiment does not limit the specific structure of single cycloneless actuators and described.

[0064] The gravity leveling method provided in this ...

Embodiment 3

[0066] This embodiment provides an engineer, and is similar to that of the first and examples of the second embodiment, the setting of the center of gravity is only different, and other settings of the drone may refer to the first embodiment or implementation. Example 2 is set, the present embodiment will not be described again.

[0067] The center of gravity trimming device 1 provided in this embodiment includes: a vertically connected first rail 11 and a second rail 12, the first rail 11 can rotate about the centerline of the longitudinal direction, and the second rail 12 can be along the first track 11. The length direction slides, slides on the second track 12, and the weight block 13 can slide in the longitudinal direction of the second track 12.

[0068] In this embodiment, the center of gravity is capable of sliding by the weight block 13 on the second track 12, the sliding action of the second track 12 on the first track 11 can be made The weight of the weight is operated ...

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and specifically discloses a method for balancing the center of gravity of an unmanned aerial vehicle and the unmanned aerial vehicle. Wherein, the UAV includes a rotor and a plurality of drive control units for driving the rotor to rotate, and the trim control method includes: obtaining input PWM signals of a plurality of drive control units; The PWM signal is used to obtain the current tilt state of the drone; according to the current tilt state, the center of gravity of the drone is adjusted until the input PWM signals of all the drive control units are the same. The center of gravity of the drone is trimmed using the center of gravity trimming method described above. The center-of-gravity balancing method and the unmanned aerial vehicle disclosed by the invention can improve the flight stability and service life of the unmanned aerial vehicle.

Description

Technical field [0001] The present invention relates to the field of UAV, in particular, to a center of gravity leveling method and a drone. Background technique [0002] UAV is an unmanned aircraft that uses radio remote control equipment or the self-propelled program control. With the continuous development of information technology and drone technology, drones are widely used in land measurement, environmental monitoring, aerial photography And parcels and other areas. [0003] Existing drones are divided into non-man-drones and manned drones. For unmanned drones, they need to carry the load required to complete the task, such as the drone who needs an aviation, it needs to be equipped Shooting equipment, for drones that need to be packaged, they need the package to be delivered. When the center of gravity of its load is not on the same vertical line, the unmanned opportunity is biased when the center of gravity of the drone itself is in the same vertical line. For man-loaded ...
