Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a heavy-duty UAV structure. Background Technology
[0002] A cargo drone is a type of drone capable of carrying and transporting goods. They are typically designed for aerial cargo delivery and can carry various types and sizes of goods, from small packages to large equipment. They have applications in many fields, including agriculture, logistics, and healthcare. For example, in healthcare, drones are widely used to transport medicines between hospitals in different locations within a city, accelerating the delivery process and reducing the inconvenience caused by traffic jams or traffic lights.
[0003] However, most existing heavy-duty drones simply place medicines directly into the cargo box at the bottom of the drone without any securing mechanism. This causes the medicines to shake during transport, resulting in an imbalance of forces on the drone and affecting its stability during flight.
[0004] Furthermore, the protective effect is poor, and the load-bearing boxes are mostly open. In the event of an accident, objects may be thrown from a height, which increases the safety hazards when using the device. Utility Model Content

[0032] More specifically, the user can place the medicine box to be transported inside the load box 2 and position it in a relatively central position. Then, the user controls the bidirectional motor 4 to rotate the lead screw 5. At this time, the lead screw 5 will drive the clamping plate 7 to move, so that the anti-slip pad 25 on the inner wall of the clamping plate 7 abuts against the two sides of the medicine box, thereby achieving the effect of fixing it.
