Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a compound-wing UAV that is easy to assemble. Background Technology

[0002] Easy-to-assemble compound wing drones are small, lightweight, and easy-to-carry multi-functional drones that combine the vertical take-off and landing capabilities of multi-rotor drones with the long endurance and range of fixed-wing drones. They are usually less expensive and more suitable for personal and small organizations.

[0003] When using the easy-to-assemble compound-wing UAV, the wings and support frame are first assembled and fixed to the fuselage through a bolt connection. Then, the drive equipment drives the propeller to rotate, thereby generating lift and lifting the easy-to-assemble compound-wing UAV. Then, the drive motor drives the front propeller to rotate, thereby providing auxiliary thrust and moving the easy-to-assemble compound-wing UAV.

[0004] Existing easy-to-assemble compound-wing UAVs, while capable of assembling and fixing the wings and support frame to the fuselage via bolted connections, are relatively cumbersome to operate and take a relatively long time to assemble. Moreover, during flight, due to vibration and maneuvering, the bolted connections may gradually loosen, thus affecting flight stability. Therefore, we propose an easy-to-assemble compound-wing UAV. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a compound wing UAV that is easy to assemble. It can replace the traditional method of assembling wings and support frames by connecting them with bolts, ensuring stability during flight, shortening the assembly time, and further improving assembly efficiency. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a compound wing unmanned aerial vehicle (UAV) that is easy to assemble, comprising a body, with wings inserted into mounting slots on the upper sides of both the left and right ends of the body, mounting frames provided at the lower ends of the wings, propellers provided at the upper ends of the mounting frames, support frames inserted into connecting slots in the middle of the lower end of the body, insertion holes provided at the front and rear ends of the wings, slots provided on the upper sides of the front and rear ends of the support frames, and a fixing mechanism;

[0007] The fixing mechanism includes a connecting plate, insert rods, and insert posts. The connecting plate is slidably connected to the bottom wall of the fuselage. Insert rods and insert posts are respectively provided on the upper and lower sides of the end of the connecting plate near the center of the fuselage. The insert rods are installed in conjunction with the longitudinally adjacent insert holes, and the insert posts are installed in conjunction with the longitudinally adjacent slots. This mechanism can replace the traditional method of assembling the wing and support frame by bolt connection, ensuring stability during flight, shortening the assembly time, and further improving assembly efficiency.

[0008] Furthermore, it also includes a control switch assembly, which is located outside the machine body. The input terminal of the control switch assembly is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0009] Furthermore, the fixing mechanism also includes a bidirectional screw and an adjusting plate. The bidirectional screw is rotatably connected to the lower side of the front wall of the machine body, and the adjusting plate is slidably connected to the lower side of the machine body. The adjusting plate is threaded to the front and rear sides of the outer arc surface of the bidirectional screw through the threaded hole in the middle of its front end. The ends of two horizontally adjacent connecting plates away from the center of the machine body are in contact with the end of an adjusting plate close to the center of the machine body, so that the position of the connecting plate can be adjusted.

[0010] Furthermore, the fixing mechanism also includes an adjusting motor, which is located on the lower side of the rear wall of the machine body. The front end of the adjusting motor output shaft is fixedly connected to the rear end of the bidirectional screw, and the input end of the adjusting motor is electrically connected to the output end of the control switch group, so that the position of the adjusting plate can be adjusted by the bidirectional screw.

[0011] Furthermore, motors are respectively installed on the front and rear sides of the upper end of the mounting frame, and propellers are installed on the upper end of the motor output shafts. The input ends of the motors are electrically connected to the output ends of the control switch group, which can generate lift through the propellers, thereby driving the easily assembled compound wing UAV to rise.

[0012] Furthermore, a front propeller is rotatably connected to the middle of the front end of the fuselage, and a drive motor is installed on the front side inside the fuselage. The front end of the output shaft of the drive motor is fixedly connected to the rear end of the front propeller, and the input end of the drive motor is electrically connected to the output end of the control switch group, which can provide auxiliary thrust to drive the easily assembled compound wing UAV to move.

[0013] Furthermore, a fixed rod is provided on the upper side of the body, and two longitudinally adjacent connecting plates are slidably connected to the front and rear sides of the outer arc surface of a fixed rod. A spring is provided between the end of the connecting plate away from the center of the body and the interior of the body. The springs are all sleeved on the outside of the fixed rod. The tension generated by the spring contraction can drive the connecting plate to move and reset.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-assemble compound-wing UAV has the following advantages:

[0015] The connecting plate, propelled by the adjusting plate, moves towards the end closer to the center of the fuselage, allowing the insert rod and insert post to engage with the insertion hole and slot respectively. This enables the assembly of the easily assembled compound wing UAV, replacing the traditional method of assembling the wing and support frame through bolted connections. This ensures flight stability, shortens assembly time, and further improves assembly efficiency. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This embodiment provides a technical solution: a compound wing unmanned aerial vehicle that is easy to assemble, including a body 1, with wings 3 inserted into the mounting slots on the upper sides of the left and right ends of the body 1, mounting frames 4 provided at the lower ends of the wings 3, propellers 6 provided at the upper ends of the mounting frames 4, support frames 11 inserted into the connecting slots in the middle of the lower end of the body 1, insertion holes provided at the front and rear ends of the wings 3, slots provided on the upper sides of the front and rear ends of the support frames 11, and a fixing mechanism 9.

[0024] Fixing mechanism 9 includes a connecting plate 92, a rod 93, and a post 94. The connecting plate 92 is slidably connected to the bottom wall of the body 1. The upper and lower sides of the end of the connecting plate 92 near the center of the body 1 are respectively provided with the rod 93 and the post 94. The rod 93 is installed in conjunction with the longitudinally adjacent insertion hole, and the post 94 is installed in conjunction with the longitudinally adjacent slot. Fixing mechanism 9 also includes a bidirectional screw 95 and an adjusting plate 96. The bidirectional screw 95 is rotatably connected to the lower side of the front wall of the body 1. The adjusting plate 96 is slidably connected to the lower side of the interior of the body 1. The adjusting plate 96 is threaded to the front and rear sides of the outer arc surface of the bidirectional screw 95 through the threaded hole provided in the middle of its front end. The ends of two laterally adjacent connecting plates 92 away from the center of the interior of the body 1 are each connected to an adjusting plate 96. The plate 96 contacts the end of the body 1 near the center of the interior. The fixing mechanism 9 also includes an adjusting motor 91, which is located on the lower side of the rear wall of the body 1. The front end of the output shaft of the adjusting motor 91 is fixedly connected to the rear end of the bidirectional screw 95. The input end of the adjusting motor 91 is electrically connected to the output end of the control switch group 2. The connecting plate 92 is pushed by the adjusting plate 96 and begins to move towards the end closer to the center of the interior of the body 1, thereby allowing the insertion rod 93 and the insertion post 94 to be inserted into the insertion hole and slot respectively. This realizes the assembly of the easy-to-assemble compound wing UAV, replacing the traditional method of assembling the wing 3 and the support frame 11 by bolt connection, ensuring flight stability, shortening the assembly time, and further improving assembly efficiency.

[0025] It also includes a control switch group 2, which is located outside the machine body 1. The input terminal of the control switch group 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0026] Among them: motors 5 are respectively installed on the front and rear sides of the upper end of the mounting frame 4. Propellers 6 are installed on the upper end of the output shaft of each motor 5. The input end of each motor 5 is electrically connected to the output end of the control switch group 2. The output shaft of the motor 5 drives the propeller 6 to rotate, thereby generating lift, which in turn drives the easily assembled compound wing UAV to rise.

[0027] The front propeller 7 is rotatably connected to the middle of the front end of the fuselage 1. A drive motor 8 is installed on the front side inside the fuselage 1. The front end of the output shaft of the drive motor 8 is fixedly connected to the rear end of the front propeller 7. The input end of the drive motor 8 is electrically connected to the output end of the control switch group 2. The output shaft of the drive motor 8 drives the front propeller 7 to rotate, thereby providing auxiliary thrust, which in turn drives the easily assembled compound wing UAV to move.

[0028] Among them: a fixed rod 10 is provided on the upper side of the inside of the body 1. Two longitudinally adjacent connecting plates 92 are slidably connected to the front and rear sides of the outer arc surface of a fixed rod 10. A spring 12 is provided between the end of the connecting plate 92 away from the center of the inside of the body 1 and the inside of the body 1. The spring 12 is sleeved on the outside of the fixed rod 10. The tension generated by the contraction of the spring 12 can drive the connecting plate 92 to move and reset.

[0029] The working principle of the easily assembled compound-wing UAV provided by this utility model is as follows: During the operation of the easily assembled compound-wing UAV, the wing 3 and the support frame 11 are first inserted into the interior of the body 1. Then, by controlling the switch group 2, the regulating motor 91 starts to run. The output shaft of the regulating motor 91 drives the bidirectional screw 95 to rotate. The bidirectional screw 95 drives the adjusting plate 96 to move through the threaded connection, so that the distance between the two adjusting plates 96 gradually decreases. At this time, the connecting plate 92 is pushed by the adjusting plate 96 and begins to move towards the end closer to the center of the interior of the body 1. Spring 12 extends, allowing the insertion rod 93 and insertion post 94 to engage with the insertion hole and slot respectively, thereby assembling the easy-to-assemble compound-wing UAV. Then, by controlling the switch group 2, motor 5 starts running, and the output shaft of motor 5 drives propeller 6 to rotate, thereby generating lift and lifting the easy-to-assemble compound-wing UAV. Then, by controlling the switch group 2, drive motor 8 starts running, and the output shaft of drive motor 8 drives the front propeller 7 to rotate, thereby providing auxiliary thrust and moving the easy-to-assemble compound-wing UAV.

[0030] It is worth noting that the motor 5 and drive motor 8 disclosed in the above embodiments can be ECMA-C20604RS, the regulating motor 91 can be 5IK200A-AF, and the control switch group 2 is provided with control buttons corresponding to the motor 5, drive motor 8 and regulating motor 91 for controlling their switching.
