Description

Technical Field

[0001] The utility model relates to the technical field of aircraft, in particular to a cardboard unmanned aerial vehicle. Background Art

[0002] Cardboard drones have been used in actual combat due to their advantages such as light weight, low cost and easy assembly, and have also received a lot of attention and discussion internationally. Cardboard drones include structures such as fuselage, wings and propellers, among which the fuselage and wings are disposable components, while internal propellers and other modules are reusable. During assembly, it is necessary to assemble the propellers and other modules into the fuselage, and assemble the wings and other structures into the fuselage and fix them to the fuselage. Some cardboard drones in the prior art use rubber bands to fix the fuselage and wings. Generally, two fixing columns are provided on both sides of the fuselage, and the two fixing columns are distributed along the front and rear directions of the wing. The rubber band is in the shape of a strip, one end of which is fixed to the fixing column at the front end, and the rubber band is passed around the top of the wing, and the other end of the rubber band is fixed to the fixing column at the rear end. The wing is fixed to the fuselage by the pressure of the rubber band on the wing. The fuselage and wings of this structure are positioned only by their original structure, and the positioning is unreliable. During the installation of the rubber band, since the rubber band needs to be installed in the front-to-back direction, the rubber band will produce unbalanced pressure on the wing, which will cause the wing to deflect or shift relative to the fuselage. Even if the rubber band is installed and readjusted, it is difficult to ensure the accuracy of the relative position between the fuselage and the wing, thus affecting the flight quality of the drone. Some cardboard drones also have positioning grooves on the top of the fuselage, so that the wings can be stuck in the positioning grooves. Although this can increase the positioning effect between the fuselage and the wings to a certain extent, the wings may still deflect or shift when subjected to unbalanced forces, affecting the flight quality of the drone. Utility Model Content

DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below. Figures 1 to 8The embodiment of the utility model provides a cardboard drone, including a fuselage body 100, a wing body 200 and an elastic fixing sleeve 300. A first mounting position 110 is provided at the top of the fuselage body 100, a wing embedding portion 120 is provided at the rear of the first mounting position 110, and a first fixing structure 130 is provided at both sides of the fuselage body 100. The wing body 200 is provided with a second mounting position 210, and a wing embedding groove 220 is provided at the rear of the second mounting position 210. The second mounting position 210 can be engaged with the first mounting position 110, and the wing embedding portion 120 is inserted into the wing embedding groove 220. After the wing embedding portion 120 is embedded in the wing embedding groove 220, the wing embedding portion 120 can form the wing of the cardboard drone with the wing body 200. The wing body 200 is also provided with a second fixing structure 230, and two second fixing structures 230 are distributed on both sides of the fuselage body 100. There are two elastic fixing sleeves 300, which are respectively mounted on both ends of the wing body 200, and each elastic fixing sleeve 300 is elastically hung on the first fixing structure 130 and the second fixing structure 230 on the same side to fix the fuselage body 100 and the wing body 200. It should be noted that the front direction here is the nose direction of the drone, and the rear direction is the tail direction of the drone.

[0025] As can be seen from the above structural description, the present cardboard drone is provided with a first mounting position 110 on the fuselage body 100, and a second mounting position 210 on the wing body 200. The first mounting position 110 cooperates with the second mounting position 210 to achieve preliminary positioning of the fuselage body 100 and the wing body 200. The present cardboard drone is also provided with a wing including a wing body 200 and a wing embedding portion 120 provided on the fuselage body 100. The wing embedding portion 120 cooperates with the wing embedding groove 220 on the wing body 200, which not only achieves further positioning between the fuselage body 100 and the wing body 200, but also maintains the original shape structure of the wing, thereby preventing the wing shape structure from being damaged and affecting the flight of the drone. The cardboard drone is initially positioned by the first mounting position 110 and the second mounting position 210 and further positioned by the wing embedding portion 120 and the wing embedding groove 220, and then the fuselage body 100 and the wing body 200 are fixed by the elastic fixing sleeve 300. On the one hand, the positioning effect between the fuselage body 100 and the wing body 200 is increased. When the elastic fixing sleeve 300 is hung, it is not easy for the fuselage body 100 and the wing body 200 to deflect or shift. The elastic fixing sleeve 300 is set on the wing body 200 in the form of a sleeve. When hanging, force can be applied in the up and down directions on both sides of the fuselage body 100 instead of installing it in the front and back directions, thereby preventing the wing from being subjected to unbalanced force in the front and back directions, and further avoiding deflection or displacement between the fuselage body 100 and the wing body 200, which can not only make the fuselage body 100 and the wing body 200 reliably fixed together, but also ensure the accuracy of the relative position between the fuselage body 100 and the wing body 200 without damaging the overall shape structure of the wing, thereby improving the flight quality of the UAV.

[0026] Furthermore, if Figure 3 As shown, the first installation position 110 is a groove opened on the top of the fuselage body 100. Figure 4 As shown, the second installation position 210 is the original structure on the wing body 200. Here, the bottom surface of the groove on the top of the fuselage body 100 is mainly used to cooperate and limit with the bottom plane of the wing body 200, and the front side wall of the groove is used to cooperate and limit with the front side of the wing body 200 to prevent the wing body 200 from deflecting relative to the fuselage body 100. The position of the wing body 200 relative to the fuselage body 100 can be limited by the wing embedding part 120 and the wing embedding groove 220. Specifically, the outer structure of the wing embedding part 120 matches the wing body 200. When the wing embedding part 120 is embedded in the wing embedding groove 220, the wing embedding part 120 can just be integrated with the wing body 200 to form the overall shape of the wing. Specifically, the wing embedding groove 220 can be a blind groove with a bottom surface, or it can be a through groove, such as Figure 4 As shown, in order to facilitate installation, in this embodiment, the wing embedding groove 220 is a through groove.

[0027] Further, refer to Figure 2 The first fixing structure 130 includes two first fixing columns 131 distributed along the front-rear direction of the wing. The outer periphery of the first fixing column 131 is provided with a first card slot 1311. The second fixing structure 230 is a second card slot provided on the wing body 200. The upper and lower parts of the elastic fixing sleeve 300 are respectively connected to the second card slot and the first card slot 1311, which can prevent the elastic fixing sleeve 300 from slipping off the first fixing structure 130 or the second fixing structure 230. Specifically, the elastic fixing sleeve 300 can be a structure such as a rubber band. Further, referring to Figure 7 In some embodiments, the position of the first slot 1311 corresponds to the position of the second slot, that is, the elastic fixing sleeve 300 is located in the same vertical plane. Figure 8 In some other embodiments, the second slot is further protruded from the first slot 1311 on both sides, so that the elastic fixing sleeve 300 is tilted outward from bottom to top, thereby fixing the wing body 200 and better adjusting the balance at both ends of the wing body 200.

[0028] Further, refer to Figure 5 In some other embodiments, the cardboard drone further includes two reinforcing fixing ribs 400, one end of one reinforcing fixing rib 400 is fixedly connected to the first fixing column 131 at the front end of one side of the fuselage body 100, and the other end is fixedly connected to the first fixing column 131 at the rear end of the other side of the fuselage body 100, and one end of another reinforcing fixing rib 400 is fixedly connected to the first fixing column 131 at the rear end of one side of the fuselage body 100, and the other end is fixedly connected to the first fixing column 131 at the front end of the other side of the fuselage body 100, and both reinforcing fixing ribs 400 are wound around and pressed against the top of the wing. The two reinforcing fixing ribs 400 are cross-arranged at the top of the wing body 200 and press the wing downward, so as to further improve the fixing effect between the wing and the fuselage body 100, and ensure that the wing and the fuselage body 100 will not deflect or shift during the flight of the drone.

[0029] Further, refer to Figure 6, considering that when the elastic fixing sleeve 300 is pulled down and connected to the first fixing column 131, the tensions on the elastic fixing sleeves 300 on both sides are different, which results in different pressures on the front and rear sides of the wing body 200, resulting in the risk of deflection or displacement of the wing body 200. Therefore, in some other embodiments, the first fixing structure 130 also includes a second fixing column 132, the second fixing column 132 is located between the two first fixing columns 131, and the first fixing column 131 is closer to the wing body 200 than the first fixing column 131, and the outer periphery of the second fixing column 132 is provided with a third slot, and the lower part of the elastic fixing sleeve 300 is connected to the third slot. After achieving preliminary positioning and further positioning between the wing body 200 and the fuselage body 100, the upper and lower parts of the elastic fixing sleeve 300 can be clamped in the first clamping groove 1311 and the second clamping groove. At this time, the elastic fixing sleeve 300 is not yet in a tensioned state, so the wing body 200 is not subject to the force of the elastic fixing sleeve 300. Afterwards, the lower middle position of the elastic fixing sleeve 300 can be lifted, and the lower part of the elastic fixing sleeve 300 can be clamped in the third clamping groove. The elastic fixing sleeve 300 is tensioned, thereby fixing the fuselage body 100 and the wing body 200. In the process of lifting the elastic fixing sleeve 300, the upper part of the elastic fixing sleeve 300 is attached to the top surface of the wing body 200, and the lower part is wrapped around the two first fixing columns 131 in the front-to-back direction, which is equivalent to the elastic fixing sleeve 300 being subjected to tension on all sides. There are two first fixing columns 131 under the wing as force points, so the pressure on the wing is relatively balanced and uniform, and in the process of lifting the lower part of the elastic fixing sleeve 300, it is limited by the two first fixing columns 131, so the direction of the resistance force generated by the elastic fixing sleeve 300 on the wing body 200 will not change much, further reducing the possibility of the wing being subjected to unbalanced pressure, thereby further improving the positioning effect between the wing and the fuselage body 100, and avoiding deflection or displacement between the wing and the fuselage body 100.

[0030] Furthermore, the fuselage is fixed and formed by cardboard and hot melt adhesive, and the fuselage and wings can be made of cardboard such as foam cardboard or corrugated cardboard. Of course, the cardboard material used in the cardboard drone is a prior art and will not be described in detail here. A plurality of reinforcing ribs are provided inside the fuselage body 100 to increase the structural strength of the fuselage body 100. The cardboard drone also includes an upper tail 500 and a lower tail 600 arranged at the tail of the fuselage body 100. The upper tail 500 is also a vertical tail, which is used to achieve the heading balance, stability and control of the drone, and the lower tail 600 is also a horizontal tail, which is used to achieve the longitudinal balance, stability and control of the drone. Of course, the control modules of the upper tail 500 and the lower tail 600 are ready-made modules, which are installed inside the fuselage body 100, and their control principles are prior art and will not be described in detail here.

[0031] Furthermore, an electric duct is provided at the front end of the fuselage body 100, a first wheel frame 700 is connected to the front lower part of the fuselage body 100, front wheels 710 are rotatably connected to both sides of the first wheel frame 700, a second wheel frame 800 is connected to the rear lower part of the fuselage body 100, a steering handle 810 is rotatably connected to the second wheel frame 800, and a steering wheel 820 is rotatably connected to the steering handle 810. Through the action of the front wheel 710 and the steering wheel 820, the drone can glide on the ground, and the steering wheel 820 can make the drone turn. Similarly, the driving module for driving the drone to glide and turn is also a ready-made module, and its control principle is also a prior art, which is not elaborated here. Specifically, the first wheel frame 700 is a ladder frame, which can increase the connection strength between the first wheel frame 700 and the fuselage body 100 while ensuring that the two front wheels 710 are symmetrically arranged. Specifically, the first wheel frame 700 and the second wheel frame 800 can be detachably connected to the lower part of the fuselage body 100 by using bolts or other structures.
