Description

Technical Field

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

[0002] A multi-rotor drone is a special type of unmanned helicopter with three or more rotor shafts. It generates lift and thrust by rotating rotors via an electric motor on each shaft. Unlike conventional helicopters, the collective pitch of the rotors is fixed. By changing the relative speeds between the different rotors, the thrust per shaft can be altered, thus controlling the aircraft's trajectory. Due to its unique structure and flight principles, multi-rotor drones are widely used in aerial photography, rescue, logistics, and performances. In the logistics and delivery sector, multi-rotor drones have demonstrated certain advantages, such as the ability to quickly and flexibly reach areas with poor transportation access, theoretically improving delivery efficiency.

[0003] However, existing multi-rotor drones face numerous pressing issues when performing logistics delivery tasks. First, payload limitations have become a major bottleneck. With the development of e-commerce, consumers are purchasing increasingly diverse and weight-sensitive goods. Existing multi-rotor drones, due to insufficient payload capacity, cannot transport some heavy items, significantly limiting their application in logistics delivery. For example, existing multi-rotor drones struggle to transport small appliances and furniture. Second, high mechanical maintenance costs are also a significant problem. Multi-rotor drones rely on multiple rotor shafts and their associated motors working in tandem. Their complex mechanical structure makes repairs difficult and costly if any component malfunctions. This not only increases the operating costs of logistics companies but may also lead to prolonged periods of drone unavailability, impacting delivery timeliness.

[0004] Therefore, the limitations of payload and high maintenance costs of existing multi-rotor drones in logistics delivery severely restrict their versatility and application scope, urgently requiring an innovative solution to promote the further development of multi-rotor drones in the logistics delivery field.

[0014] Specifically, the drone body includes a frame body, an upper shell cover disposed on the frame body, and multiple power modules arranged regularly along the edge of the frame body;

[0015] The main frame includes an upper fixed clamping plate and a lower fixed clamping plate arranged in parallel, a number of long and short crossbeams regularly arranged and fixedly connected between the upper and lower fixed clamping plates for reinforcement of the machine body, and a machine arm with one end fixedly connected between the upper and lower fixed clamping plates and the other end housing a power module. The number of machine arms matches the number of power modules.

[0016] Specifically, the arm includes an arm beam fixedly connected to the main frame body at one end, an arm fixing plate fixedly connected to the other end of the arm beam, and an extension rod connected to the arm fixing plate through a snap-fit ​​device.
