Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) take-off platform technology, specifically a UAV take-off platform. Background Technology

[0002] Drone launch platforms are typically built on the ground or on buildings, with a fixed structure and location. Such platforms can provide a stable surface for drone takeoff and landing.

[0003] The patent document with patent publication number CN218559205U describes a drone take-off platform. By designing a dual-purpose (land and water) drone take-off platform consisting of a base frame, take-off plate, electric push rod, air pump, first air bag, second air bag, and GPS positioning chip, it is easy to carry and use, which is conducive to users taking off and landing rotary-wing drones flexibly on land and water, increasing operational flexibility.

[0004] However, the aforementioned takeoff platform lacks lift functionality. On a platform without lift capability, the takeoff and landing process for drones can be more complex. Operators need to control the drone's altitude and position more precisely; even slight errors could lead to collisions or loss of control, increasing the risk of flight accidents.

[0005] Based on this, a drone takeoff platform is now provided that can eliminate the drawbacks of existing platforms. Utility Model Content

[0006] The purpose of this utility model is to provide a drone take-off platform to solve the problem in the background art where the aforementioned platforms lack lift functionality, leading to easy collisions or loss of control during drone take-off and landing, and increasing the risk of flight accidents.

[0007] To achieve the above objectives, this utility model provides the following technical solution:
