Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicles (UAVs), in particular to a rotating folding four-rotor UAV. Background Art

[0002] Quadcopter drones have four arms and rotors attached to each arm. Because their unfolded structure is relatively large, the market is generally considering designing the arms to be foldable and stowable. The main solution is to design the arms with multi-section, foldable shafts, which are folded downward to achieve folding. However, designing the entire arm as a multi-section inevitably reduces its stability and torque resistance. Furthermore, folding and stowing requires high operational requirements. Therefore, a quadcopter drone is in high demand that can achieve foldability while ensuring the stability and torque resistance of the arms. Utility Model Content

[0003] In view of the above problems existing in the prior art, a rotating folding quad-rotor drone is now provided to overcome at least one of the above technical defects.

[0004] The specific technical solutions are as follows:

[0005] A rotating folding quadrotor drone, comprising:

[0006] rotating disk;

[0007] A transverse machine arm, horizontally mounted on the lower end surface of the rotating disk;

[0008] A longitudinal machine arm, movably mounted horizontally on the upper end surface of the rotating disk;

[0009] In addition, rotor assemblies are respectively provided at both ends of the transverse and longitudinal arms, and the longitudinal arms are capable of rotating around the center of the rotating disk, and have the ability to be maintained in an expanded state in a cross-staggered arrangement with the transverse arms, and to be rotated to a stowed state in which the longitudinal arms overlap with the transverse arms in a top-down perspective.

[0010] Preferably, a through hole is opened in the middle of the rotating disk, and a rotating support assembly is embedded in the through hole, and the rotating support assembly includes an upper rotating part and a lower rotating part that are coaxially connected, and the upper rotating part can rotate circumferentially relative to the lower rotating part, and the upper end surface of the upper rotating part and the lower end surface of the lower rotating part both have an arc-shaped concave surface for supporting the machine arm.

[0011] Preferably, a pin is respectively provided between the middle portion of the longitudinal machine arm and the upper rotating member, and between the middle portion of the transverse machine arm and the lower rotating member.

[0012] Preferably, two arc-shaped grooves are mirror-imaged on the rotating disk, and two limit pins are passed through the longitudinal machine arm, and the lower end of each limit pin extends into one of the arc-shaped grooves to limit the rotation path of the longitudinal machine arm.

[0013] Preferably, the arc angle of the arc groove is 90 degrees.

[0014] Preferably, one end of the limit pin passing downward through the arc-shaped slot is further connected to a locking piece.

[0015] Preferably, two support seats are symmetrically mounted on the lower end surface of the rotating disk, and each of the support seats is formed with an arc-shaped concave surface for supporting the horizontal machine arm.

[0016] Preferably, the transverse machine arm and the longitudinal machine arm are respectively connected to support legs extending in a downward direction through clamps, and the four support legs together constitute the landing gear.

[0017] Preferably, the rotor assemblies at both ends of the longitudinal arm are arranged in an upward direction, and the rotor assemblies at both ends of the transverse arm are arranged in a downward direction.

The longitudinal arm and the transverse arm are respectively mounted on the upper and lower end surfaces of the rotating disk, and the longitudinal arm has an unfolded state and a stowed state, so that the arm and the wing can be unfolded and stowed by rotating the longitudinal arm. There is no need to design the arm into a multi-section structure and stow it in a folding structure, which makes the arm more structurally stable and has higher torque resistance.

[0021] (2) One end of the limit pin that passes downward through the arc groove is also connected to a locking piece, which, on the one hand, prevents the limit pin from falling out of the arc groove upward, and on the other hand, can lock and maintain the state after the longitudinal machine arm is rotated to the expanded state or the retracted state.

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the accompanying drawings to explain the present invention in detail. Figure 3 The direction from top to bottom shown on the paper is the direction from back to front in this embodiment, the left and right directions shown on the paper are the left and right directions in this embodiment, and the direction perpendicular to the paper and inward is the direction from top to bottom in this embodiment.

[0030] See Figures 1 to 6 As shown in , the rotating folding quad-rotor drone provided in this embodiment includes:

[0031] Rotating disk 1;

[0032] The horizontal arm 3 is horizontally mounted on the lower end surface of the rotating disk 1;

[0033] The longitudinal arm 2 is movably mounted horizontally on the upper end surface of the rotating disk 1;

[0034] In addition, rotor assemblies 4 are respectively provided at both ends of the transverse arm 3 and the longitudinal arm 2, and the longitudinal arm 2 can rotate around the center of the rotating disk 1, and has the ability to be maintained in an expanded state in a cross-arrangement with the transverse arm 3, and to be rotated to a stowed state in which it overlaps with the transverse arm 3 when viewed from above.

[0035] Based on the above technical solution, the rotating folding quadrotor drone includes a rotating disk 1, a transverse arm 3, and a longitudinal arm 2. The longitudinal arm 2 and the transverse arm 3 are respectively installed on the upper and lower end surfaces of the rotating disk 1, and the longitudinal arm 2 has an expanded state and a stored state, so that the arm and wings can be expanded and stored by rotating the longitudinal arm 2. There is no need to design the arm into a multi-section structure and cooperate with a folding structure for storage, which makes the structural stability of the arm higher and the torque resistance of the arm higher.

[0036] In a preferred embodiment, combined Figure 4 、 Figure 5 as well as Figure 7 As shown in the figure, a through hole is provided in the middle of the rotating disk 1, and a rotating support assembly 7 is embedded in the through hole. The rotating support assembly 7 includes an upper rotating member 11 and a lower rotating member 10 that are coaxially connected. The upper rotating member 11 can rotate circumferentially relative to the lower rotating member 10, and the upper end surface of the upper rotating member 11 and the lower end surface of the lower rotating member 10 both have arc-shaped concave surfaces for supporting the machine arm. Furthermore, pins are respectively provided between the middle of the longitudinal machine arm 2 and the upper rotating member 11, and between the middle of the transverse machine arm 3 and the lower rotating member 10, so that the longitudinal machine arm 2 can rotate with the upper rotating member 11 and serve as the central support structure of the machine arm.

[0037] As a further preferred embodiment, two mirror-image arcuate slots 8 are formed on the rotating disk 1, and two stop pins are inserted into the longitudinal arms 2. The lower end of each stop pin extends into one of the arcuate slots 8 to limit the rotation path of the longitudinal arms 2. Furthermore, the arcuate slots 8 have an arc angle of 90 degrees to achieve the purpose of cross-interlacing the two arms. However, they can also be designed to be larger or smaller, so that the interlacing angle of the two arms is obtuse or acute, and close to a right angle, which can also achieve the above-mentioned purpose. Furthermore, the end of the stop pin that extends downward through the arcuate slot 8 is connected to a locking member. This prevents the stop pin from upwardly exiting the arcuate slot 8, and it also locks and maintains the longitudinal arms 2 in the extended or stowed state after rotation. Furthermore, two support seats 9 are symmetrically mounted on the lower end surface of the rotating disk 1, and each support seat 9 has a curved concave surface for supporting the transverse arms 3.

[0038] In a preferred embodiment, combined Figure 1 and Figure 2 As shown in the figure, the horizontal arm 3 and the longitudinal arm 2 are respectively connected to the support legs 5 extending in the downward direction through a clamp, and the four support legs 5 together constitute the landing gear, which serves as the support of the entire drone on the ground and allows it to rotate synchronously to the storage state when the longitudinal arm 2 rotates.

[0039] As a further preferred embodiment, the rotor assemblies 4 at both ends of the longitudinal arms 2 are arranged in an upward direction, and the rotor assemblies 4 at both ends of the transverse arms 3 are arranged in a downward direction, so that they can be staggered with each other in the stored state.

[0040] In a preferred embodiment, combined Figure 7 As shown in , the rotating disk 1 is also rotatably provided with an upper cover 6, and the opposite sides of the upper cover 6 have a gap for passing the longitudinal machine arm 2. When specifically used, the upper cover 6 can rotate together with the longitudinal machine arm 2.

[0041] In addition, the rotor assembly 4 is configured on the arm, and it has a communication receiver, a motor and a rotor, and can be operated by the received signal. Alternatively, an electrically connected main controller and power supply assembly can be further arranged in the upper cover 6. The communication module or motor control end of each rotor assembly 4 can be connected to the main controller along the tube channel in the arm, and the main controller can uniformly control the actions of each rotor assembly 4, which can realize the basic functions of the drone. This is a solution commonly adopted in existing related products and is not the main innovation of this solution, so it is omitted here.

[0042] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
