Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and specifically provides an inter-wing connection structure of an unmanned aerial vehicle. Background Art

[0002] Most drones on the market currently use direct line connection or active plugs for connection. Although this method can achieve quick disassembly and installation of the main wing and outer wing, when disassembling the outer wing, repeated plugging and pulling can easily damage the line, causing the drone to not work properly. Especially in an emergency, it may bring more serious consequences.

[0003] Even drones that use quick-connect methods still require additional connectors to secure the plug, which not only increases the weight of the drone and reduces its endurance, but also affects its aerodynamic performance and flight performance because the additional connectors do not match the aerodynamic shape. Utility Model Content

The outer wing PCB is completely fitted with the inner surface of the outer wing skin. The outer wing PCB is provided with through holes of the same number and shape as those of the outer wing connecting beam. The outer wing connecting beam passes through the through holes and is glued to the outer wing PCB.

[0009] The main wing PCB circuit board and the outer wing PCB circuit board are respectively fixed with a main wing plug and an outer wing plug, and the axial fixation and electrical connection of the main wing and the outer wing are achieved through the main wing plug and the outer wing plug.

[0010] Preferably, the main wing connecting beam and the outer wing connecting beam are both made of carbon fiber material.

[0011] Preferably, it comprises 2 main wing connecting beams and 2 outer wing connecting beams.

[0015] Compared with the prior art, the utility model can achieve the following beneficial effects:

In the following description, the same modules are represented by the same reference numerals. In the case of the same reference numerals, their names and functions are also the same. Therefore, the detailed description thereof will not be repeated.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and do not constitute a limitation of the utility model.

[0026] like Figure 1 As shown, an embodiment of the utility model provides a connection structure between the wings of an unmanned aerial vehicle, which is mainly used for the rapid disassembly of the main wing and the outer wing of the unmanned aerial vehicle, wherein all structures are pre-buried inside the skin of the unmanned aerial vehicle. A main wing plug 3, a main wing PCB circuit board 4, a main wing front connecting beam 5, a main wing rear connecting beam 6 and a main wing circuit line 7 are arranged inside the main wing skin 1. Among them, the main wing PCB circuit board 4 is arranged vertically with the inner surface of the main wing skin 1, and is glued to the edge of the connection position between the main wing and the outer wing by an adhesive. The shape of the contact surface between the main wing PCB circuit board 4 and the main wing skin 1 is the same as the surface shape of the inner surface of the main wing skin 1, so that the main wing PCB circuit board 4 is completely fitted with the main wing skin 1. A main wing plug 3 is soldered in the middle position of the main wing PCB circuit board 4 by soldering, and the main wing plug 3 is connected to the main wing circuit line 7 on the rear side of the main wing PCB circuit board 4 by routing on the main wing PCB circuit board 4. On the main wing PCB circuit board 4 on both sides of the main wing plug 3, there is a circular through hole, which is used for the main wing front connecting beam 5 and the main wing rear connecting beam 6 to pass through the two through holes respectively, and the main wing front connecting beam 5 and the main wing rear connecting beam 6 are glued to the main wing PCB circuit board 4 at the through hole position by adhesive.

[0027] Similarly, an outer wing plug 8, an outer wing PCB circuit board 9, an outer wing front connecting beam 10, an outer wing rear connecting beam 11, and an outer wing circuit line 12 are arranged inside the outer wing skin 2. Among them, the outer wing PCB circuit board 9 is arranged vertically to the inner surface of the outer wing skin 2, and its position corresponds to the main wing PCB circuit board 4, and is glued to the edge of the connection position between the main wing and the outer wing by an adhesive. The shape of the contact surface between the outer wing PCB circuit board 9 and the outer wing skin 2 is the same as the surface shape of the inner surface of the outer wing skin 2, so that the outer wing PCB circuit board 9 and the outer wing skin 2 are completely fitted. An outer wing plug 8 is soldered in the middle position of the outer wing PCB circuit board 9 by soldering, and the outer wing plug 8 corresponds to the position of the main wing plug 3, which is used to achieve connection with the main wing plug 3. The outer wing plug 8 is connected to the outer wing circuit line 12 on the rear side of the outer wing PCB circuit board 9 by routing on the outer wing PCB circuit board 9. On the outer wing PCB circuit board 9 on both sides of the outer wing plug 8, there is a circular through hole, and the outer wing front connecting beam 10 and the outer wing rear connecting beam 11 pass through the two through holes respectively. The outer wing front connecting beam 10 and the outer wing rear connecting beam 11 are glued to the outer wing PCB circuit board 9 by adhesive at the through hole position. The position of the through hole on the outer wing PCB circuit board 9 should correspond to the position of the through hole on the main wing PCB circuit board 4, so that the sleeve connection can be achieved after the connecting beam is fixed.

[0028] In the above structure, the main wing plug 3 and the outer wing plug 8 are a pair of structures that can achieve mechanical and electrical connection, wherein the mechanical locking structure of the main wing plug 3 and the outer wing plug 8 can adopt common buckles, spring locks or other connection locking structures to achieve the axial connection between the main wing and the outer wing. At the same time, one end of the main wing plug 3 and the outer wing plug 8 is an electrical male connector, and the other end is an electrical female connector. Through the connection between the main wing plug 3 and the outer wing plug 8, the main wing circuit line 7 and the outer wing circuit line 12 are connected, and then the main wing and the outer wing are connected to the UAV electrical system, realizing the UAV's electrical control and information transmission of the main wing and the outer wing.

[0029] In this embodiment, only two main wing connecting beams and outer wing connecting beams are provided. When the wing width is wider, the number of connecting beams can be increased to ensure that the number of main wing connecting beams and outer wing connecting beams is equal and the positions are corresponding, and the sleeve connection can be realized accordingly. In addition, in this embodiment, the main wing connecting beam and the outer wing connecting beam are both made of carbon fiber material, and the shape is a hollow circular tube. Since the sleeve connection is adopted, the inner diameter of the main wing connecting beam is required to be the same as the outer diameter of the outer wing connecting beam, and the outer wing connecting beam is inserted into the main wing connecting beam, or the outer diameter of the main wing connecting beam is the same as the inner diameter of the outer wing connecting beam, and the main wing connecting beam is inserted into the outer wing connecting beam.

[0030] The above structure is applied to the connection between the main wing and the outer wing of the drone. The connection process is briefly described as follows:

The main wing mold 13 is consistent with the shape of the main wing, and the outer wing mold 14 is consistent with the shape of the outer wing. During the installation process, the main wing and the outer wing are placed on the wing mold 13 and the outer wing mold 14 respectively to ensure the position of the main wing mold 13 and the outer wing mold 14. The main wing plug 3 and the outer wing plug 8 are placed in the main wing limit insert 15 and the outer wing limit insert 16 respectively to ensure that the main wing plug 3 and the outer wing plug 8 are accurately positioned during installation, so that the actual installation position and size can be guaranteed to be consistent with the installation position and size theoretically in the drawing, and the main wing plug 3 and the outer wing plug 4 can be accurately docked.
