[0002] With technological advancements and the changing landscape of modern warfare, the importance of low-cost unmanned aerial vehicles (UAVs) in both military and civilian applications has become increasingly prominent. Large numbers of low-cost UAVs in battlefield environments can achieve a wider range of applications than traditional large, expensive drones. Therefore, solutions are needed to reduce the cost of UAVs.

[0003] Compared to drones, aircraft models offer significant price advantages. However, due to differences in production materials and application areas, they cannot meet the basic requirements of conventional drones: autonomous driving and independence from a takeoff and landing site. Therefore, developing a modification module based on traditional aircraft models, which can combine the advantages of low cost with vertical takeoff and landing and autonomous driving capabilities, is a technology with broad application prospects. Summary of the Invention

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the implementation of this application will be described in more detail below in conjunction with the drawings in the implementation of this application. In the drawings, the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions. The described implementation is a part of the implementation of this application, not all of the implementations. The implementation described below with reference to the drawings is exemplary and is intended to be used to explain this application, and should not be understood as a limitation on this application. Based on the implementation in this application, all other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The implementation of this application is described in detail below in conjunction with the drawings.

[0016] In the description of the present invention, it should be understood that the terms "center", "axial", "vertical", "up", "down", "upper end", "bottom end", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0017] This invention relates to a special device that can cost-effectively convert ordinary aircraft models into vertical take-off and landing (VTOL) drones. This device, assembled from simple, inexpensive parts, forms an H-shaped quadrotor lift layout. This device can be quickly installed at the center of gravity of any aircraft model, creating a drone capable of vertical take-off and landing and autonomous flight. This conversion requires no complex process or damage to the original aircraft model, allowing for rapid conversion and restoration, and is adaptable to aircraft models of varying sizes.

[0018] The present application is described in further detail below with reference to the accompanying drawings of the embodiments.

[0019] like Figure 1-4 The present invention provides a lift module that can be used to convert a fixed-wing aircraft model into a vertical take-off and landing function. The module forms a four-rotor lift body structure through a simple and fast assembly of parts, and has its own flight control module. It can quickly convert a traditional aircraft model into a drone capable of vertical take-off and landing without the need for extensive modification and at low cost.

[0020] The module includes: a carbon fiber horizontal beam 1; a flight control installation box 2; a T-shaped adapter joint 3, a carbon fiber longitudinal beam 4, a lift motor bracket 5, a lift motor 6, a lift propeller 7, a motor bracket adjustment pin 8, a power cord 9, and a parallel plug 10.

[0021] Among them, the carbon fiber horizontal beam 1 passes through the center of the model aircraft fuselage, with the flight control installation box 2 fixed in the middle; two T-shaped adapters 3 are inserted at the left and right ends of the carbon fiber horizontal beam 1, and the two T-shaped adapters 3 are vertically inserted into two carbon fiber longitudinal beams 4 respectively; four lift motor brackets 5 are fixed to the ends of the carbon fiber longitudinal beams 4, and the lift motors 6 are installed on them; four lift propellers 7 are installed on the shafts of lift motors 6. Motor bracket adjustment pins 8 pass through the holes of the lift motor brackets 5 and are fixed to the carbon fiber longitudinal beams 4; power cords 9 connect the four lift motors 6 and are connected to the aircraft model's power supply through parallel plugs 10.

[0022] The flight control mounting box 2 is provided with a buckle and a latch. After the carbon fiber horizontal beam 1 passes through the aircraft model fuselage, the middle part of the carbon fiber horizontal beam 1 is clamped to fix the entire module. No glue or screws are required, which facilitates the disassembly and assembly of the entire module. The carbon fiber horizontal beam 1 and the carbon fiber longitudinal beam 4 are made of carbon fiber square tubes, which are light in weight and high in strength. Compared with round tubes, square tubes have a natural installation plane and will not produce relative rotation when inserted into the T-shaped adapter 3, which is more beneficial to the force and installation of the H-shaped module. The length of the carbon fiber longitudinal beam 4 of each module can be adjusted according to the size of the aviation model to be modified, which is convenient for adapting to different aviation models and realizing universal modification. A row of adjustable adjustment pin mounting holes are set at both ends of the carbon fiber longitudinal beam 4. By inserting and removing the motor bracket adjustment pin 8, the position of the lift motor bracket 5 at both ends of the carbon fiber longitudinal beam 4 can be fine-tuned to control the center of gravity position of the entire aircraft model and achieve the best flight effect; The lift motor bracket 5 has universal mounting holes, which can be adapted to lift motors 6 of different sizes according to the size of the modified aircraft model, so that aircraft models of different sizes can be modified; The power cord 9 is independently connected to the four lift motors 6 and matched with the parallel plug 10. There is no need to damage the wires and power system of the original aircraft model, so the modification is more convenient and can be quickly restored to its original state. Parts such as the flight control mounting box 2, the T-shaped adapter 3 and the lift motor bracket 5 can be manufactured using a plastic 3D printing process, which meets the strength requirements, has a fast production speed and is low in cost.

[0023] The module has the advantages of low cost, easy and quick modification, and rapid optimization of the center of gravity for different types of model aircraft. It can be quickly mass-produced and upgrade the model aircraft to a vertical take-off and landing drone.

[0024] How this module works: The above components can convert an ordinary aircraft model into a low-cost drone with vertical take-off and landing capabilities: a hole is opened at the center of gravity of the aircraft model fuselage, and the hole size is the same as the cross-sectional size of the carbon fiber horizontal beam 1; the carbon fiber horizontal beam 1 is inserted into the aircraft model fuselage, and after ensuring that the left and right lengths are the same, the flight control installation box is clamped in the middle of the fuselage, which not only fixes the carbon fiber horizontal beam 1 but also provides an installation position for the flight control; a T-shaped adapter 3 is inserted into the left and right ends of the carbon fiber horizontal beam 1, and then two carbon fiber longitudinal beams 4 are inserted along the direction of the fuselage to form a load-bearing structure that is "H"-shaped when viewed from above.

[0025] There are four lift motor brackets 5. The lower portion of each bracket has a square hole with the same cross-section as the carbon fiber stringer 4, and the upper portion has threaded holes for mounting the lift motors 6. First, install the four lift motors 6 on each bracket 5, then thread the four lift motor brackets 5 through the ends of the carbon fiber stringer 4. The carbon fiber stringer 4 has a row of equally spaced mounting holes. Depending on the model's center of gravity, the lift motor brackets 5 can be moved forward and backward along the flight path to adjust the center of gravity to the desired level and avoid flight failure. Different aircraft models correspond to different hole positions. After adjustment, insert the four motor bracket adjustment pins 8 into the mounting holes to secure and lock the lift motor brackets 5. Finally, secure the four lift propellers 7 to the shafts of the lift motors 6. Connect the power cords 9 to the four lift motors 6 and the flight controller, respectively. Use a parallel plug to connect the power cords 9 in parallel with the aircraft model's existing batteries to provide power.

[0026] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
