The development of modular UAVs starts with the modularization of the UAV frame structure, which involves the connection between modules.

[0003] Most existing modular drone rack modules are connected by tiny screws. The large number of tiny fixings makes the disassembly and assembly process very difficult, and the scalability is poor. As for the modular design that uses magnetic connection nodes, the problems of insufficient strength and poor stability are difficult to solve. Summary of the invention

[0008] Preferably, the transverse member includes a transverse embedded block and transverse expansion blocks symmetrically distributed at both ends of the transverse embedded block, the transverse embedded block is pressed into the axial member, the upper and lower planes of the transverse member and the axial member are respectively coplanar, and the connecting socket for extended connection is provided at the end of the transverse expansion block.

[0009] Preferably, the middle portion of the longitudinal member is a cylindrical rod, and the two ends of the longitudinal member are movably connected to the cylindrical rod and rotate in the planes where the two end surfaces of the cylindrical rod are located.

[0010] Preferably, the splicing joint comprises an isosceles triangular prism, whose vertex angle is 360 / n degrees, n is a positive integer, and the splicing structure is arranged on the side surfaces on both sides of the vertex angle of the triangular prism. When multiple mortise sub-node joints or multiple tenon sub-node joints are spliced, the splicing joints of the axial parts are arranged in sequence and assembled and connected through the splicing structure, so that the vertex angle of the spliced ​​joint after splicing is expanded to 360m / n degrees, and m is the number of mortise sub-node joints or multiple tenon sub-node joints involved in the splicing.

[0011] Preferably, the top angle of the splicing joint is 120 degrees.

[0012] Preferably, the modular mortise and tenon joints include three types:

[0013] Single honeycomb module vertex: single mortise and tenon subnode joints and tenon and tenon subnode joints are connected by mortise and tenon joints or rod socket connections;

[0014] Two honeycomb modules share a common vertex: two mortise sub-node joints are spliced ​​to form a double honeycomb mortise node, two tenon sub-node joints are spliced ​​to form a double honeycomb tenon node, and the double honeycomb mortise node and the double honeycomb tenon node are mortise-jointed or connected by rod jacking;

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] (1) The present invention designs modular mortise and tenon joints based on traditional woodworking structures. A single mortise joint and a single tenon joint are combined into a single module. Each single module includes 6 independent components, namely, axial components, transverse components and longitudinal components in the mortise joint and the tenon joint. There are no tiny fixing components such as screws that are inconvenient to disassemble quickly in the structure, which greatly reduces the time and difficulty of assembly / disassembly. The locking and unlocking of the single module are achieved by rotating the two ends of the longitudinal component, which greatly improves the stability of the structure.

[0021] (2) The present invention provides a connection jack as an expansion port, so that the function of providing different numbers of expansion ports can be realized by splicing and combining multiple single modules, thereby achieving the purpose of free stacking and expansion of honeycomb modules;

[0022] (3) The joint is designed to be assembled from multiple parts to form sub-nodes, which are then assembled into complete nodes. This allows users to select nodes according to actual needs, which greatly expands the applicability of the joint and improves its scalability, thereby effectively completing the construction of a variety of structures.

[0023] (4) The joint is assembled from multiple parts. When local damage occurs, only the damaged parts need to be replaced, which has the characteristic of low maintenance cost.

[0024] (5) Various forms of mortise and tenon joints are used between the various components, which means that there are no tiny fixings such as screws that are inconvenient to disassemble in the overall structure of the node joint, greatly reducing the time and difficulty of assembly / disassembly.

[0025] (6) The components are locked to each other, which makes the structure extremely stable. Even if a locked component is damaged, it cannot be separated from the whole due to the restrictions on its displacement in all directions by other components, which greatly improves the reliability of the node joint.

[0026] (7) After the node joint is fully assembled, the only degree of freedom left is the rotation of the longitudinal part around the longitudinal axis. Under normal use and without human interference, the longitudinal part cannot rotate on its own and has good overall stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] A splicing joint is arranged at one end of the axial member, and a splicing structure is arranged on the splicing joint. A transverse rectangular groove for pressing the transverse member and a semi-cylindrical through hole for pressing the axial member are arranged in the middle of the axial member, and the semi-cylindrical through hole is adjacent to the transverse rectangular groove. A connecting socket for extended connection is arranged at one end of the axial member.

[0047] The transverse member includes a transverse embedded block and transverse expansion blocks symmetrically distributed at both ends of the transverse embedded block. The transverse embedded block is pressed into the axial member. The upper and lower planes of the transverse member and the axial member are coplanar. The end of the transverse expansion block is provided with a connecting jack for extended connection.

[0048] The middle part of the longitudinal member is a cylindrical rod, and the two ends of the longitudinal member are respectively movably connected with the cylindrical rod and rotate respectively on the planes where the two end faces of the cylindrical rod are located.

[0049] The splicing joint includes an isosceles triangular prism, whose vertex angle is 360 / n degrees, n is a positive integer, and the splicing structure is arranged on the side surfaces on both sides of the vertex angle of the triangular prism. When multiple mortise sub-node joints or multiple tenon sub-node joints are spliced, the splicing joints of the axial parts are arranged in sequence and assembled and connected through the splicing structure, so that the vertex angle of the splicing joint after splicing is expanded to 360m / n degrees, and m is the number of mortise sub-node joints or multiple tenon sub-node joints involved in the splicing.
