Description

Technical Field

[0001] This invention belongs to the field of teaching aids for disassembling and assembling drone wheels, and in particular relates to a teaching aid for disassembling and assembling drone wheels and its usage method. Background Technology

[0002] With the popularization of drone technology, the demand for training drone pilots and maintenance personnel is increasing. The disassembly and assembly of drone landing gear wheels is a basic and important skill in maintenance. Currently, there are two main traditional training methods: one is operation on a real drone, and the other is theoretical learning through watching videos or reading diagrams.

[0003] Operating on a real drone has the following drawbacks:

[0004] 1. High cost: Frequent disassembly and assembly can easily lead to stripped threads on the landing gear of real drones, wear or damage to parts, and high training costs.

[0005] 2. High risk: Trainees are not proficient in operating the equipment and may damage core components due to improper use of tools or inaccurate tightening torque, which may even affect flight safety.

[0006] 3. Low teaching efficiency: The compact structure of real drones makes it difficult for all students to observe the operational details at the same time, and it is also inconvenient for instructors to provide guidance.

[0007] Purely theoretical learning methods lack hands-on practice, preventing students from developing muscle memory and practical experience, resulting in unsatisfactory teaching outcomes.

[0008] Therefore, there is an urgent need for a teaching aid that is specifically designed for practical training, is low in cost, durable, and can simulate the real disassembly and assembly process. Summary of the Invention
