A training drone

Abstract

This utility model discloses a training drone, including a drone controller assembly, a live connector, a boom assembly, a protective plate, a connecting plate, landing gear legs, a landing gear base plate, and a non-live connector. By incorporating both live and non-live connectors, the boom assembly, protective plate, landing gear legs, and landing gear base plate can be quickly assembled and disassembled via either the live or non-live connector. Both the live and non-live connectors are internally equipped with anti-detachment locking blocks. When the insertion tube and connecting tube are inserted, the locking block one engages with the slot, and the elastic potential energy of the spring ensures the stability of the mechanical connection. Simultaneously, the locking block two in the anti-detachment locking block assembly inserts between two movable plates, forming a double locking mechanism to effectively prevent loosening of the connection due to vibration during flight. When the drone falls due to operational errors, damaged legs or the base plate can be quickly replaced, and flight training can resume immediately after the replacement, greatly reducing wasted teaching time.

Description

Technical Field

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

[0002] With the rapid development of drone technology, its application in the education field has gradually become more widespread. Especially in teaching and training, drones have become an important tool for cultivating students' practical abilities and innovative thinking. However, existing teaching and training drones still have many shortcomings in their design, which limit their teaching effectiveness and ease of maintenance.

[0003] First, the structural design of traditional teaching drones is relatively fixed, with the boom and landing gear lacking modularity. The components are usually rigidly connected, often using irreversible methods such as bolts, welding, or gluing. This design makes disassembly and assembly complex for students. At the same time, because drone operation requires high hand-eye coordination and spatial awareness, beginners are prone to operational errors during flight practice, leading to frequent collisions and falls. Collisions or falls can easily damage protective plates, booms, or landing gear. However, existing designs lack a quick replacement mechanism for vulnerable parts. Students are often forced to suspend their learning due to a single collision, waiting for time-consuming and costly repairs, which seriously affects the continuity of teaching and students' enthusiasm.

The outer end of the first 25 extends out of the insertion tube 21 and is interlocked with the slot 24. The top center of the connecting tube 22 is equipped with an anti-detachment block assembly 28, which is used to support the two movable plates 23. The right end of the insertion tube 21 is fixed to the edge of the drone controller assembly 1. The inner wall of the connecting tube 22 fits against the outer wall of the insertion tube 21 to ensure a stable connection between the insertion tube 21 and the connecting tube 22. The right side of the first 25 is set at an angle so that when the insertion tube 21 is inserted into the connecting tube 22, the first 25 automatically retracts. The length and width of the outer end of the first 25 are both greater than five millimeters, which makes it easy for the user to press the first 25 with their fingers to retract it.

[0030] The live connector 2 also includes a first power plug 201, a first power socket 202, a second power plug 203, and a second power socket 204.

[0031] Please see Figure 7The anti-detachment locking block assembly 28 includes a fixed frame 281, an operating block 282, a straight rod 283, a second locking block 284, and a second spring 285. The operating block 282 is located at the top center of the fixed frame 281. The straight rod 283 vertically penetrates the middle of the top wall of the fixed frame 281, and its top end is fixedly connected to the operating block 282. The bottom end of the straight rod 283 is fixedly connected to the second locking block 284. The top end of the second locking block 284 is elastically connected to the inner top wall of the fixed frame 281 via the second spring 285, and the second spring 285 is fitted onto the outside of the straight rod 283. The fixed frame 281 is fixed to the top of the connecting tube 22, and the top of the insertion tube 21... A through hole corresponding to the second card block 284 is provided on the right side of the end. After the through hole is aligned with the position of the second card block 284, the second card block 284 extends into the insertion tube 21 and is located between the two movable plates 23. The second card block 284 fits against the two movable plates 23 in the extended state. Before the first card block 25 is inserted into the slot 24, the two movable plates 23 contract, and the top of the movable plates 23 supports the second card block 284. During the process of inserting the insertion tube 21 into the connecting tube 22, the first card block 25 is inserted into the slot 24 first. After the first card block 25 and the slot 24 are engaged, the second card block 284 is inserted between the two movable plates 23.

[0032] The left side of the second locking block 284 is inclined, and the top of the second locking block 284 is wide and the bottom is narrow. The top wall of the connecting pipe 22 has a through hole that communicates with the fixed frame 281. The second locking block 284 is used to support the two movable plates 23.

[0033] Please see Figure 3 The outrigger assembly 3 includes a support ring 31, a motor mounting bracket 32, a motor 33, a rotor 34, and a support rod 35. The motor mounting bracket 32 ​​is fixed to the inner wall of the support ring 31. The motor 33 is installed at the top center of the motor mounting bracket 32. The output shaft at the top of the motor 33 is connected to the rotor 34 for transmission. The right side of the support ring 31 is fixedly connected to the support rod 35, and the right side of the support rod 35 is fixedly connected to the insertion tube 21 by bolts. The left side of the support ring 31 is connected to the protective plate 4 through a non-electric connector a2.

[0034] Please see Figure 8-9 The non-electric connector a2 consists of a insertion tube 21, a connecting tube 22, a movable plate 23, a slot 24, a locking block 25, a limiting rod 26, a spring 27, and an anti-disengagement locking block assembly 28. Compared with the structure of the live connector 2, the non-electric connector a2 has an additional power socket 202, a power plug 203, and a power socket 204. The non-electric connector a2 has the same structure and connection method as the live connector 2, consisting of the insertion tube 21, connecting tube 22, movable plate 23, slot 24, locking block 25, limiting rod 26, spring 27, and anti-disengagement locking block assembly 28.

[0035] When using the drone, if the accessories are damaged, the damaged parts can be disassembled for replacement or repair. Since each part is connected by a live connector 2 or a non-live connector a2, when it is necessary to disassemble the damaged part, simply disconnect the live connector 2 or the non-live connector a2 at the connection point. By pulling up the operating block 282 of the live connector 2 or the non-live connector a2, the operating block 282 drives the locking block 284 to move upward through the straight rod 283. By pressing the locking block 25, the locking block 25 drives the movable plate 23 to squeeze the spring 27, causing the two movable plates 23 to retract, thereby causing the locking block 25 to disconnect from the slot 24. The insertion tube 21 can then be pulled out from the connecting tube 22, disconnecting the connection between the two parts of the drone. The disassembled drone parts can then be replaced or repaired. When replacing, the insertion tube 21 and the connecting tube 22 on the damaged part are removed from the damaged part and installed on the new part.

[0036] When the component needs to be installed, simply connect the insert tube 21 on the component to the corresponding connecting tube 22, or connect the connecting tube 22 on the component to the corresponding insert tube 21. When the insert tube 21 is connected to the connecting tube 22, the locking block 25 is supported by the insertion port of the connecting tube 22, causing the locking block 25 to retract. During the process of inserting the insert tube 21 into the connecting tube 22, the inclined end of the locking block 284 is squeezed, causing the locking block 284 to move upward. After the locking block 25 moves to be aligned with the slot 24, the elastic potential energy generated by the spring 27 pushes it upward. The two movable plates 23 are expanded together, allowing the first locking block 25 to be inserted into the slot 24. At this time, since the right side of the top of the insertion tube 21 has a through hole corresponding to the second locking block 284, after the through hole is aligned with the position of the second locking block 284, the second spring 285 generates elastic potential energy, causing the second locking block 284 to extend into the insertion tube 21. Since the movable plates 23 are expanded together at this time, the second locking block 284 is inserted between the two movable plates 23, increasing the fastening effect of the first locking block 25 and the slot 24, and ensuring the connection between the drone components is stable.

[0037] When the outrigger assembly 3 is fixed to the drone controller assembly 1 via the live connector 2, the circuits of the first power plug 201, the first power socket 202, the second power plug 203, and the second power socket 204 are automatically connected, thereby automatically completing the circuit connection between the motor 3 on the outrigger assembly 3 and the drone controller assembly 1.
