Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a novel intelligent UAV for training. Background Technology

[0002] Traditional drone take-off and landing systems mostly use rigid supports or simple spring buffers, lacking a damping and shock absorption mechanism. When taking off and landing on uneven ground (such as grass or gravel roads), the ground reaction force is directly transmitted to the fuselage, causing the fuselage to sway by more than 15°, or even tip over. Data shows that the success rate of existing drones taking off and landing on ground with a slope of ≥10° is only 60%-70%, and the buffer structure is prone to failure after multiple impacts (lifespan is about 50-100 take-offs and landings), which cannot meet the high-frequency take-off and landing requirements of 20-30 times per day in training scenarios.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This utility model provides a new technical solution: a new type of intelligent training drone, including a control box 1 and a protective component. The protective component is set on the control box 1 and includes a mounting frame 12. The mounting frame 12 is fixedly connected to the outer surface of the control box 1, and the end of the mounting frame 12 away from the control box 1 is fixedly connected to the mounting box 9.

[0030] Among them, the lower surface of the mounting box 9 is fixedly connected to the mounting base plate 19, and the outer surface of the mounting base plate 19 is fixedly connected to four fixing plates 14. The end of each of the four fixing plates 14 away from the mounting base plate 19 is fixedly connected to a movable sleeve 13.

[0031] Among them, the inner walls of the four movable sleeves 13 are all slidably sleeved with slide rods 18, and the upper surfaces of the four slide rods 18 are all fixedly connected with limit plates 15.

[0032] Among them, the lower surfaces of the four sliding rods 18 are fixedly connected with circular stabilizing plates 10, which are used to contact the ground.

[0033] Furthermore, buffer springs 16 are movably sleeved on the outer walls of the four slide bars 18, and the lower ends of the four buffer springs 16 are fixedly connected to the circular stabilizing plate 10.

[0034] A damper 17 is fixedly installed on the upper surface of the circular stabilizing plate 10, and the damper 17 is fixedly installed together with the mounting base plate 19.

[0035] Furthermore, an arc-shaped mounting plate 8 is fixedly connected to the outer wall of the mounting box 9, and two L-shaped fixing rods 7 are fixedly connected to the outer surface of the arc-shaped mounting plate 8. An arc-shaped protective rod 5 is fixedly connected to the upper surface of the two L-shaped fixing rods 7.

[0036] Furthermore, two second fixing rods 4 are fixedly connected to the inner wall of the arc-shaped protective rod 5, and a protective ring 3 is fixedly connected to the end of the two second fixing rods 4 away from the arc-shaped protective rod 5.

[0037] Furthermore, a first fixing rod 2 is fixedly connected to the outer surface of the protective ring 3, and the end of the first fixing rod 2 away from the protective ring 3 is fixedly installed together with the control box 1;

[0038] The system consists of four protective components, all of which have identical structures.

[0039] Furthermore, a hollow cup motor 6 is fixedly installed on each of the four mounting boxes 9, and a drive shaft 11 is fixedly connected to the output end of each of the four hollow cup motors 6.

[0040] Furthermore, fan blades are fixedly installed on the upper ends of the four drive shafts 11, and the shape of the fan blades can be selected according to the actual situation.

[0041] Furthermore, when using this new type of training intelligent drone, the operator first starts four hollow cup motors 6 through the control terminal. The output end of the hollow cup motors 6 drives the transmission shaft 11 to rotate at high speed, driving the fan blades to generate lift, so that the drone can take off smoothly.

[0042] When the drone needs to land, the circular stabilizing plate 10 makes contact with the ground first. The ground reaction force is transmitted to the movable sleeve 13 through the sliding rod 18. The sliding rod 18 slides upward along the inner wall of the movable sleeve 13, compressing the buffer spring 16 and triggering the damper 17 to work.

[0043] Among them, the buffer spring 16 absorbs the impact energy during landing through elastic deformation, reduces the vertical vibration of the fuselage, and avoids damage to the internal components of the control box 1 caused by rigid collision.

[0044] Among them, the damper 17 converts the impact kinetic energy into heat energy consumption through the damping effect of the viscous medium, and forms a composite buffer with the buffer spring 16 to ensure that the circular stabilizing plate 10 touches the ground smoothly and reduces the shaking of the machine body.

[0045] In the event of a collision or scrape during flight, the physical protection structure consisting of the arc-shaped protective rod 5 and the protective ring 3 will first come into contact with the obstacle. The arc design will disperse the impact force to the L-shaped fixed rod 7 and the first fixed rod 2 on both sides. Through the rigid support of the mounting bracket 12 and the mounting box 9, the impact force will be transmitted to the entire protective assembly, preventing the control box 1 from being directly subjected to force.

[0046] Among them, the four protective components are symmetrically distributed, which can evenly withstand the impact force from different directions. The protective ring 3 wraps around the key parts of the control box 1, and with the curved surface guide of the arc-shaped protective rod 5, the risk of sharp objects puncturing the fuselage is reduced.

[0047] When it is necessary to adjust the flight attitude, the speed difference of the hollow cup motor 6 generates vector thrust. The UAV can turn, hover or dive in the air by adjusting the speed and angle of the fan blades. When taking off and landing on the ground, the sliding cooperation between the slide bar 18 and the moving sleeve 13 ensures that the stabilizing plate always touches the ground in parallel. The preload of the buffer spring 16 can adapt to different ground hardness, improving the reliability of UAV take-off and landing on uneven ground.

[0048] After the operation is completed, the buffer spring 16 resets, the slide bar 18 returns to its initial position under the constraint of the limit plate 15, and the arc-shaped protective bar 5 and the protective ring 3 return to their natural state, ready for the next flight.

[0049] Among them, by setting up protective components, through the composite shock absorption of buffer spring 16 and damper 17, the three-dimensional protection of arc-shaped protective structure and the stable design of symmetrical layout, the impact resistance and take-off and landing stability of drones in training scenarios are effectively improved, reducing equipment damage caused by operational errors or environmental interference, meeting the reliability requirements of high-frequency use of training drones, and thus improving the service life of new training intelligent drones.

[0050] The new intelligent training drone employs both optical flow positioning and tag positioning. Optical flow positioning enables precise location perception in indoor environments, while tag positioning provides more possibilities for flight positioning in specific scenarios. The laser altitude hold mode ensures the drone maintains a stable altitude throughout flight, unaffected by airflow or other factors, resulting in smoother flight.

[0051] Among them, the new training intelligent drone has functions such as visual recognition, RGB lighting, and voice control, adding endless fun to flying. Visual recognition can realize operations such as target tracking. It also has expansion modules such as laser obstacle avoidance, laser target shooting, infrared target shooting, photography, and mechanical claw (which can be installed according to specific circumstances) to meet the needs of different users in scientific research, entertainment, and work.

[0052] Among them, the new training intelligent drone is equipped with a 2.4G communication remote controller, has a built-in display screen, can view the sensor status in real time, making it convenient for users to understand the drone's status at any time, and can easily set the flight mode. The multi-drone formation function can be realized through formation software.

[0053] This intelligent drone has a wheelbase of approximately 120mm and overall dimensions of 178mm in length, 178mm in width, and 45mm in height (including the protective cover). It is compact and weighs approximately ≤88g (including the battery and protective cover), making it lightweight and portable. It can flexibly handle both indoor and outdoor flight.
