Description

Technical Field

[0001] The utility model relates to an automatic folding polar unmanned aerial vehicle structure, belonging to the technical field of unmanned aerial vehicles. Background Art

[0002] With the continuous development of modern science and technology, the application of robots is becoming more and more extensive. Robots are mechanical devices that perform work automatically. They can accept human commands, run pre-programmed programs, or act according to principles formulated by artificial intelligence technology. Its task is to assist or replace human work, such as manufacturing, construction, or dangerous work. For example, due to its complex terrain and harsh climatic conditions, the polar regions require robots to have stable and efficient performance to replace human polar work.

[0003] At present, most of the existing polar monitoring drones are equipped with emergency support vehicles, which are used to charge or recover the monitoring drones. However, the existing drones are large in size, which makes the emergency support vehicles larger, inconvenient to carry, and is not conducive to cost control of the entire polar expedition. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art, the utility model provides an automatic folding polar UAV structure which has a simple structure and whose UAV arms can be folded and does not occupy space.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is an automatic folding polar UAV structure, including a UAV body, a supporting leg installed at the bottom of the UAV body, and arms installed at the four corners of the UAV body through an automatic rotation mechanism, a UAV motor is installed at the end of the arm, a rotor is installed on the UAV motor, and the length of the arm is less than the height from the center of the automatic rotation mechanism to the ground; the automatic rotation mechanism includes a mounting seat installed on the UAV body and a servo installed in the mounting seat, the output shafts on both sides of the servo extend to the outside of the mounting seat, and a U-shaped control board is installed on the output shafts on both sides of the servo, the arm is fixed on the U-shaped control board, and an upper baffle for limiting the U-shaped control board is also installed on the upper part of the mounting seat.

[0006] Preferably, two magnetic sheets and position detection points are symmetrically installed on both sides of the drone motor, and the position detection point is located in the middle of the two magnetic sheets. A position sensor and magnets installed on both sides of the position sensor are installed on the arm, and the magnets correspond to the magnetic sheets, and the position sensor corresponds to the position detection point.

[0007] Preferably, a protective cover is installed outside the mounting seat and the steering gear, and the protective cover is made of carbon fiber material.

[0008] Preferably, the position sensor and the steering gear are respectively connected to the UAV control system.

[0009] Preferably, the suction force of the magnet on the magnetic sheet is much smaller than the torque of the drone motor.

[0010] Compared with the prior art, the utility model has the following technical effects: the utility model has a simple structure and a reasonable design. The arm of the drone is designed to be an automatically foldable structure, and the arm is folded 90 degrees by a servo, so that the drone can be placed in the nest without taking up space. At the same time, the position sensor and the magnet cooperate to detect the rotation position of the drone motor through the position sensor, and the magnet is used to attract the magnetic suction sheet to accurately locate the rotation position of the drone motor, so that when the arm is folded, the rotor of the drone is located in the vertical direction of the arm, which can greatly reduce the space occupied and ensure that the rotor is not damaged. At the same time, the volume of the nest is reduced, the weight is reduced, the cost is reduced, and it is easy to transport and install. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0014] like Figure 1 to Figure 2 The invention discloses an automatic folding polar UAV structure, comprising a UAV body 1, a supporting leg 2 being installed at the bottom of the UAV body 1, an arm 4 being installed at the four corners of the UAV body 1 through an automatic rotating mechanism 3, a UAV motor 5 being installed at the end of the arm 4, a rotor 6 being installed on the UAV motor 5, and a length of the arm 4 being less than a height from the center of the automatic rotating mechanism to the ground; the automatic rotating mechanism 3 comprises a mounting seat 7 installed on the UAV body 1 and a steering gear 8 installed in the mounting seat, output shafts on both sides of the steering gear 8 extending to the outside of the mounting seat 7, and U-shaped control panels 9 being installed on the output shafts on both sides of the steering gear 8, the arm 4 being fixed on the U-shaped control panel 9, and an upper baffle 10 for limiting the U-shaped control panel being also installed on the upper part of the mounting seat 7.

[0015] The utility model adopts an automatic rotating mechanism 3 to install an arm 4 at the four corners of the drone body 1, and the automatic rotating mechanism 3 can control the arm 4 to fold downward. When the drone is working, the arm is in a horizontal state; when it is not needed, the arm is in a vertical state. The automatic rotating mechanism 3 is controlled by a dual-output servo, and the folding angle of the arm can be controlled by the servo. An upper baffle 10 is also installed on the upper part of the mounting seat 7, which can control the U-shaped control panel, and can also ensure that when the arm is in a horizontal state, the position of the automatic rotating mechanism 3 can have sufficient strength, and can also ensure the smooth operation of the drone. A protective cover 15 is also installed on the outside of the mounting seat 7 and the servo, and the protective cover 15 is made of carbon fiber material. The protective cover can protect the mounting seat 7 and the servo.

[0016] Among them, two magnetic sheets 11 and position detection points 12 are symmetrically installed on both sides of the drone motor 5, and the position detection point 12 is located in the middle of the two magnetic sheets 11. The arm 4 is equipped with a position sensor 13 and a magnet 14 installed on both sides of the position sensor. The magnet 14 corresponds to the magnetic sheet 11, and the position sensor 13 corresponds to the position detection point 12. The position sensor 13 and the servo 8 are connected to the drone control system respectively. Considering that when the arm is folded, the rotor of the drone must be in a vertical state with the arm, so as to ensure that the rotor is not damaged when folded. The position sensor 13 and the magnet 14 are used to control the rotation angle of the drone motor when it stops. The position sensor 13 can detect the stop rotation angle of the drone motor in real time, and at the same time use the magnet to attract the magnetic sheet to control the stop rotation of the drone motor. The suction force of the magnet 14 on the magnetic sheet 11 is much smaller than the torque of the drone motor 5, ensuring that the magnet has no effect on the drone motor 5.

[0017] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
