Embodiment Construction
[0030] Below in conjunction with accompanying drawing, the present invention is described in detail:
[0031] Such as figure 1 As shown, the modular frame structure of the unmanned helicopter of the present invention includes three modules of the front frame 1, the middle frame 2 and the rear frame 3, and each module is connected with each other by screws and mortise and tenon structures.
[0032] 1. The first module: the front frame 1, the main structure is a high-strength carbon fiber structure, with a small amount of aluminum parts, screws, nuts, etc.
[0033] 2. The second module: mid-end frame 2, the main structure is a single frame part, which is made of aluminum alloy.
[0034] 3. The third module: the rear frame 3, the main structure is a high-strength carbon fiber structure, with a small amount of aluminum parts, screws, nuts, etc.
[0035] 4. The functions and connections of each part are as follows:
[0036] First Module: Front Rack
[0037] Front-end rack 1, see ...
