Problems solved by technology

The collective distance of the rotor is fixed, not as variable as that of general helicopters. By changing the relative speed between different rotors, the magnitude of the single-axis propulsion can be changed, thereby controlling the trajectory of the aircraft. The multi-rotor UAV can take off and land vertically. And hovering, mainly suitable for low-altitude, low-speed, vertical take-off and landing and hovering mission types. Some existing multi-purpose multi-rotor UAVs cannot be folded because the arms cannot be folded, which leads to inconvenient transportation and occupation of UAVs. Lots of room, room for improvement

Embodiment 1

[0032] Refer to the accompanying drawings below Figure 1-Figure 6 Describe an unmanned aerial vehicle with a foldable arm 2 according to Embodiment 1 of the present invention, the device includes a fuselage 1, an arm 2 and a rotor assembly 12, wherein the arm 2 includes a first arm tube 3 and a second arm tube 7.

[0033] Such as figure 2 , Figure 4 and Figure 6 As shown, one end of the first arm pipe 3 (such as the left end shown in the figure) is connected to the fuselage 1, and the end of the first arm pipe 3 away from the fuselage 1 (such as the right end shown in the figure) is covered with a first The snap ring 4, the outer peripheral wall of the first snap ring 4 is provided with a limit seat 5, the limit seat 5 is provided with a limit groove 6, and the limit groove 6 runs through the first arm tube 3 along the axial direction (for example, the left and right direction) One arm tube 3. In this embodiment, the first arm tube 3 is configured in a cylindrical sha...

Embodiment 2

[0044] Refer to the accompanying drawings below Figure 6-Figure 8 A UAV with foldable arms 2 according to Embodiment 2 of the present invention is described. Embodiment 2 is a further improvement on Embodiment 1.

[0045] In this example, if Figure 5 and Figure 6 As shown, the head of the bolt is provided with a plurality of rotating plates 13, and the plurality of rotating plates 13 are arranged at intervals along the circumferential direction of the bolt, so that the bolt can be turned manually without using tools such as wrenches, which is convenient for use.

[0046] In this example, if Figure 5 and Figure 6 As shown, the slide plate 10 is provided with a limiting rib 17. When the limiting rib 17 abuts against the end face of the first snap ring 4 close to the second snap ring 8, the sliding plate 10 slides into the limiting groove 6. When the limiting rib 17 When 17 abuts against the end surface of the second snap ring 8 close to the first snap ring 4 , the slide...

Abstract

The invention discloses an unmanned aerial vehicle with foldable vehicle arms. The unmanned aerial vehicle comprises a vehicle body; a first arm pipe, one end of the first arm pipe is connected with the fuselage, the end, away from the fuselage, of the first arm pipe is sleeved with a first clamping ring, a limiting base is arranged on the peripheral wall of the first clamping ring, and a limitinggroove is formed in the limiting base; a second arm pipe, one end of the second arm pipe is sleeved with a second clamping ring, the second clamping ring is rotatably connected with the first clamping ring, a sliding seat is arranged on the peripheral wall of the second clamping ring, and a sliding plate is slidably mounted on the sliding seat; a fastener connected with the limiting seat; a rotorwing assembly which is arranged at one end, far away from the first arm pipe, of the second arm pipe. The unmanned aerial vehicle has a first state and a second state, in the first state, the slidingplate slides into the limiting groove, the axis of the first arm pipe and the axis of the second arm pipe are collinear, the sliding plate is fixed to the limiting base through the fastener, in the second state, the sliding plate slides out of the limiting groove, the second arm pipe can rotate relative to the first arm pipe, and therefore the vehicle arms can be folded.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with foldable arms. Background technique [0002] A multi-rotor UAV is a UAV with three or more arms. The outer end of each arm is equipped with a lifting thrust mechanism with a motor or an engine as a power source. The motor or generator rotates to drive the rotor, thereby generating thrust. The collective distance of the rotor is fixed, not as variable as that of general helicopters. By changing the relative speed between different rotors, the magnitude of the single-axis propulsion can be changed, thereby controlling the trajectory of the aircraft. The multi-rotor UAV can take off and land vertically. And hovering, mainly suitable for low-altitude, low-speed, vertical take-off and landing and hovering mission types. Some existing multi-purpose multi-rotor UAVs cannot be folded because the arms cannot be folded, which leads to inconvenient tr...
