Problems solved by technology

The landing gear is an important part of the UAV. Most of the existing UAV landing gear is composed of two left and right support rods. This kind of landing gear is unstable and cannot find the UAV well when it lands and takes off. the central axis of the plane, causing the aircraft to capsize, causing unnecessary accidents and losses

Embodiment Construction

[0010] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0011] Such as figure 1 As shown, the anti-subversion landing gear structure of the UAV of this embodiment includes a circular base ring 1, the center of the base ring 1 is the UAV main body 2, and the base ring 1 and the UAV main body 2 pass through multiple arcs The arc-shaped rod 3 is connected, and the arc-shaped rod 3 is evenly arranged around the center of the base ring 1. The lower end of the arc-shaped rod 3 has an arc-shaped connecting end 31 that is bent outward away from the center of the base ring 1. The arc-shaped connecting end 31 and the base ring 1 Fixed connection, the base ring 1 and the drone frame 5 are connected by an inclined support rod 4, and multiple support rods 4 are evenly arranged around the center of the base ring 1.

[0012] The invention adopts a circular bracket as a whole, which better avoids the overturning accident of the drone du...

Abstract

The invention relates to an anti-overturn undercarriage structure of an unmanned aerial vehicle. The anti-overturn undercarriage structure comprises a circular base ring, wherein an unmanned aerial vehicle main body is arranged in the center of the base ring; the base ring and the unmanned aerial vehicle main body are connected through a plurality of arc-shaped rods which are uniformly arranged along the center of the base ring; outward bending arc-shaped connecting ends far away from the center of the base ring are arranged at the lower ends of the arc-shaped rods, and fixedly connected with the base ring; the base ring and an unmanned aerial vehicle frame are connected through a plurality of inclined supporting rods which are uniformly arranged along the center of the base ring. The anti-overturn undercarriage structure wholly adopts a circular bracket, so that accidents at takeoff and landing of the unmanned aerial vehicle can be well avoided; through the adoption of the anti-overturn undercarriage structure, the unmanned aerial vehicle can more quickly find the center axis while landing so as to avoid overturn accidents.

Description

Technical field [0001] The invention relates to a multi-rotor aircraft, in particular to a multi-rotor aircraft with a collision avoidance function. Background technique [0002] In recent years, small unmanned helicopters have been widely used, such as multi-rotor aircraft, which are mainly used for crop pesticide spraying services, aerial photography, forest fire prevention inspections, and public security surveillance. The landing gear is an important part of the UAV. Most of the existing UAV landing gear is composed of left and right support rods. This type of landing gear is unstable, and the UAV cannot be found well during inorganic landing and take-off. The central axis of the aircraft caused the aircraft to overturn and cause unnecessary accidents and losses. Summary of the invention [0003] In view of the above-mentioned shortcomings in the prior art, the applicant has conducted research and improvements to provide an anti-subversion landing gear structure for drones, w...
