detailed description

The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

As shown in Figure 1 and Figure 2, a six-rotor short-distance logistics drone includes a control box 1, a main connecting rod 2, a secondary connecting rod 3, a hydraulic rod 4, and a spiral collar 5; the control box 1 is A hexagonal cylinder, the ends of the main connecting rod 2 are respectively fixed on three non-adjacent sides of the control box 1, the other end of the main connecting rod 2 is fixed at the midpoint of the secondary connecting rod 3, and the main connecting rod 2 is perpendicular to the secondary connecting rod 3; the main connecting rod 2 and the secondary connecting rod 3 are hollow tubular rods; the end of the secondary connecting rod 3 is connected with a spiral collar 5 through a hydraulic rod 4, and the spiral collar 5 Rotatable; the middle position in the secondary connecting rod 3 is provided with two motors 21 to drive the propeller 53 fixed in the spiral collar 5 to rotate through the drive shaft 33 respectively, the motors 21 are connected and controlled by the control box 1, and the control box 1 is connected The circuit of the motor 21 is arranged in the main connecting rod 2 .

The engine cannot be used as the power source, and the main reason for using the motor is that, as far as the current situation is concerned, the engine generally has a large vibration range, a relatively complicated structure (need to design oil circuits and circuits), and it is not easy to control the speed (generally requires a transmission) , while the motor runs smoothly, has a simple structure (only needs a circuit), and is easy to control the speed (no need for a transmission, just control the power).

The propeller 53 is a four-blade propeller.

As a preferred solution for the rotation of the spiral collar 5, the front and rear ends of the hydraulic rod 4 are rotatably fixed to the secondary connecting rod 3 and the spiral collar 5 through a universal joint 41 respectively, and the hydraulic pipeline 42 of the hydraulic rod 4 Through the side wall of the secondary connecting rod 3, the hollow position of the main connecting rod 2 leads to the control box 1, and the hydraulic rod 4 is controlled by the control box 1; at the position where the connecting rod 3 and the spiral collar 5 approach each time, three hydraulic pressure pole 4.

Further, the corresponding helical collar 5 is rotatable. As a preferred solution for the power transmission of the driving shaft 33, the end of the driving shaft 33 engages with the driven shaft 52 through the universal joint 43 and the transmission bevel gear 44 in turn, and the driven shaft 33 engages with the driven shaft 52. The shaft 52 is coaxially fixed to the propeller 53, and a fixed block 51 is horizontally fixed in the spiral collar 5, and the driven shaft 52 is fixed on the fixed block 51 through a bearing.

As the fixing method of the driving shaft 33, there are multiple inner fixing blocks 31 in the secondary connecting rod 3, the inner fixing blocks 31 are annular protrusions protruding inward, and the inner fixing blocks 31 are coaxial with the secondary connecting rod 3; A bearing 32 is fixed inside the inner fixing block 31 , and the driving shaft 33 is sleeved in the bearing 32 .

As an important guarantee for the short-distance logistics transportation of the present invention, the length of the secondary connecting rod 3 is greater than one meter, and the length of the main connecting rod 2 is greater than 0.5 meter. Generally speaking, the length of the secondary connecting rod 3 should be greater than 1/2 of the length of the object.

Thus, when in use, the object is hoisted on the secondary connecting rod 3, and the posture of the helical collar 5 is adjusted by controlling the hydraulic rod 4 during flight, thereby adjusting the angle of the propeller 53, so that the whole can be kept stable.

Due to the adoption of the six-rotor setting, although the binding problem needs to be considered when lifting objects during use, the attitude adjustment of the helical collar 5 is easier. For the adjustment of the attitude of any helical collar 5, the specific operation range on a single hydraulic rod 4 is relatively large. Smaller and therefore last longer.

Because the motor is used as the power source, the present invention is not suitable for strong wind environment, nor is it suitable for long-distance transportation.
