Problems solved by technology
[0005] The purpose of the present invention is to provide a free-to-assemble UAV frame structure to solve the problem that most of the existing UAV frames proposed in the background technology are fixed frames, so the number of connected rotor groups is also fixed. , so there is a limit to the weight that can be loaded, it is difficult to change according to the needs of use, and although some of them can be assembled in a variety of ways, these frames are all connected by ordinary round rods, and the overall firmness is relatively strong after connection. Poor, easy to loosen the problem

Embodiment Construction
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0026] see Figure 1 to Figure 7 , an embodiment provided by the present invention: a free-to-assemble UAV frame structure, including a UAV body 1; a total of four connection seats 2 are fixed and symmetrically connected to the outside of the UAV body 1; The inner side of the top of the seat 2 is slidably embedded with a positioning plug 8; the positioning plug 8 can slide up and down on the inner side of the top of the connecting seat 2, and a spring is also arranged on the outside of the positioning rod 3, and the spring is located on the inner side of the top of the connecting seat 2. In the chute, the spring will push the positioning insert 8 to slide downward du...

The invention discloses an unmanned aerial vehicle frame structure capable of being freely assembled, relates to the technical field of unmanned aerial vehicles, and solves problems that an existing unmanned aerial vehicle frame difficultly meets different use requirements and is poor in connection firmness. The frame structure comprises a main body of UAV, four connecting bases are fixedly and symmetrically connected to the outer side of the unmanned aerial vehicle body; a positioning inserting block is mounted on the inner side of the top of each of the four connecting seats in a sliding embedding manner; the top of each positioning insertion block is fixedly connected with a positioning pull rod, and the top end of each positioning pull rod penetrates through the top of the connecting base and extends upwards; one side of each of the four connecting seats can be fixedly connected with one end of an engine arm; and a group of rotor wings are arranged at the tops of the other ends of the vehicle arms. After the connecting seat is connected with the vehicle arm, after the connecting seat is connected with the expansion frame and after the expansion frame is connected with the vehicle arm, the connecting seat, the expansion frame and the vehicle arm can be locked through the positioning insertion blocks, so the vehicle arm does not shake and does not fall off outwards after being connected, and firmness after connection is greatly improved.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a freely assembled unmanned aerial vehicle frame structure. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but equipment such as autopilot and program control device are installed. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft track, locate, remotely control, telemeter and digitally transmit it through radar and other equipment. [0003] For example, the patent application No. 201920561005.X discloses a freely assembled UAV frame structure, including an assembly kit and multiple rotors. The assembly kit includes multiple connecting rods and various connectors. The parts are assembled and connected by connecting rods, and multiple connecting rods and vari...
