Embodiment 1

[0027] Such as figure 1 As shown, this embodiment provides a device for quickly folding the arms of a multi-rotor UAV, including a fixing unit 100 and a folding unit 200 . Wherein, the fixing unit 100 is fixed on the frame of the drone, the folding unit 200 is fixed to the arm of the drone, and the folding unit 200 can be unfolded or folded relative to the fixing unit 100 .

[0028] Such as Figure 2-4 As shown, the fixing unit 100 includes a fixing frame 110 , a guide plate 120 , a connecting shaft 130 and several bolts 140 .

[0029] The fixing frame 110 includes two fixing plates 111 arranged in parallel. The fixed plate 111 is fixed on the frame for supporting other components. The shape and size of the fixing plate 111 are set according to the frame. The fixing plate 111 has a square hole 112 .

[0030] The guide plate 120 is in a “convex” shape, and both sides match the square holes 112 of the fixing plate 111 . The guide plate 120 is arranged in the fixed frame 11...

Embodiment 2

[0045] Such as Figure 10 As shown, this embodiment provides a quick-folding device for the arms of a multi-rotor UAV, which is basically the same in structure as the first embodiment, the only difference being that the limit assembly 240 also includes a return elastic member 244 . In this embodiment, the reset elastic member 244 is a spring. The spring 244 is disposed between the pin hole 2411 and the snap ring 243 .

[0046] When the limiting pin 242 is pulled out from the limiting hole 121 , the spring 244 is compressed. When the limiting pin 242 needs to be inserted, the limiting pin 242 is aligned with the limiting hole 121 , and the compressed spring 244 pushes the limiting pin 242 into the limiting hole 121 . The spring 244 can also prevent the limiting pin 242 from falling out of the limiting hole 121 when the drone performs operations such as turning over.

Abstract

The invention discloses a multi-rotor wing unmanned aerial vehicle arm fast folding device. The device comprises a fixing unit and a folding unit. The fixing unit comprises a fixing frame, a guide plate and a connecting shaft. The guide plate is fixed in the fixing frame. The folding unit comprises a connecting ear plate, the connecting ear plate has a connecting hole, the end of the connecting ear plate is provided with an opening groove, the connecting shaft passes through the fixing frame and the connecting hole, in the unfolded state, the opening groove is clamped by the guide plate, in folding, the opening groove is separated from the guide plate, the connecting hole moves on the connecting shaft and the connecting ear plate rotates around the connecting shaft. The device realizes simple unfolding and folding of an arm, can be operated conveniently and can guarantee structural strength.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles and relates to a fast folding device for arms of a multi-rotor unmanned aerial vehicle. Background technique [0002] With the rapid development of multi-rotor drone technology and the maturity of the market, multi-rotor drones have been widely used in agriculture and industry. Multi-rotor UAVs usually carry heavy loads, and require high structural strength for the folding parts of the arms. At present, the structure of the arm folder is complex and the operation is cumbersome, and it cannot be quickly folded and unfolded, which limits its application. Contents of the invention [0003] The invention provides a fast folding device for the arms of a multi-rotor UAV to overcome the defects in the prior art. [0004] In order to achieve the above object, the present invention provides a multi-rotor drone arm quick folding device, including a fixed unit and a folding unit; wherein, the fixe...
