Description

Technical Field

[0001] This invention relates to the field of remote-controlled aircraft technology, and more specifically to a remote-controlled paper airplane. Background Technology

[0002] The flight time of traditional hand-folded paper airplanes depends primarily on the folding shape, size, weight, and material of the paper. These factors limit the maximum takeoff weight of the paper airplane, making it difficult to add any additional accessories. Currently, the longest flight time for an unpowered paper airplane is only 31.2 seconds. To extend its flight time, the most direct and effective method is to add a power system. Lithium batteries, due to their light weight and high energy output, are the preferred power source. In actual tests, a lithium battery weighing only 4 grams can power a 10-gram paper airplane for 15 minutes. However, adding components such as batteries, motors, and control boards significantly increases the overall weight of the paper airplane. Therefore, a lightweight yet robust structural design is necessary to reliably secure these components.

[0003] In addition, in order to take off from the ground like a real airplane, it would be best to install a landing gear on the structural components that can be easily installed and removed.

[0004] However, in existing solutions, these power components and control modules are often fixedly connected to the paper airplane body, making them difficult to disassemble once installed. This prevents users from replacing the paper airplane body or landing gear according to different flight scenarios, severely limiting the product's versatility and flexibility of use. Summary of the Invention

[0005] The purpose of this invention is to provide a remote-controlled paper airplane with a simple structure, flexible operation, and interchangeable paper airplane body.

[0006] The specific technical solution of the present invention is as follows:

[0007] A remote-controlled paper airplane includes a main body with a long rod symmetrically fixed on both sides. A motor mounting cylinder is located at the end of each long rod, and the motor mounting cylinder is hollow, with a motor fixed inside each cylinder. A motor shaft is located outside each motor, and a propeller is fixedly connected to the motor shaft. The propeller includes a left propeller and a right propeller. A first cavity and a second cavity are located in the middle of the main body. A battery is fixed in the first cavity for power supply, and a control board is fixed in the second cavity.

[0008] Preferably, it also includes an aircraft landing gear, on which two wheels are rotatably connected on both sides, and the aircraft landing gear is detachably connected to the bottom of the main body and located in the landing gear groove at the bottom of the main body.

[0009] Preferably, the bottom of the main body is provided with a convex plate, and the convex plate is provided with a protrusion. When the aircraft landing gear is detachably connected to the landing gear groove, the protrusion abuts against the aircraft landing gear to prevent it from falling off.

[0010] Preferably, the upper part of the main body is provided with an aircraft support frame, and the aircraft support frame has a long groove in the middle for mounting an aircraft made of thin materials.

[0011] Preferably, the upper part of the main body is provided with an aircraft support frame, and the aircraft support frame has a long groove in the middle for mounting an aircraft made of thin materials.

[0012] Preferably, the aircraft support has support bars extending symmetrically to both sides.

[0013] The beneficial effects of this invention are as follows:

[0014] The remote-controlled paper airplane provided by this invention uses a movable connection method that is easy to disassemble and assemble, allowing users to flexibly replace the paper airplane body according to different flight needs or personal preferences, greatly improving the versatility and fun of the product.

[0015] In addition, the solution has a sensitive overall control response, a low operating threshold, and users can achieve stable flight without complicated training. The overall structure is simple, low-cost, safe and reliable, making it suitable as a remote control toy for children and teenagers.

Detailed Implementation

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1-6 As shown, Figure 1 As shown, the remote-controlled paper airplane 10 provided by the present invention mainly includes a main body 1. A long rod 2 is symmetrically fixed on the left and right sides of the main body 1. Both long rods 2 extend outward in the horizontal direction, and a motor fixing cylinder 3 is fixedly installed at the end of each long rod 2. The motor fixing cylinder 3 has a hollow cylindrical structure, and its internal cavity is used to accommodate and fix the motor 4.

[0026] Specifically, after the motor 4 is installed in the motor fixing cylinder 3, its motor shaft 41 extends from the front end of the motor fixing cylinder 3, and a propeller 5 is fixedly connected to the motor shaft 41. The propeller 5 located at the end of the left long rod 2 is the left propeller 51, and the propeller 5 located at the end of the right long rod 2 is the right propeller 52.

[0027] A first cavity 11 and a second cavity 12 are respectively provided in the middle of the main body 1. The first cavity 11 is used to accommodate and fix the battery 6. The battery 6 serves as the energy source for the entire power system, providing power support for the motor 4 and the control board 7. The second cavity 12 is used to accommodate and fix the control board 7. The control board 7 integrates the necessary control circuits and wireless signal receiving modules, which are used to receive external remote control commands and control the speed and start / stop of the motor 4 according to the commands, thereby realizing real-time control of the paper airplane 10.

[0028] Furthermore, a landing gear groove 13 is provided at the bottom of the main body 1. The landing gear groove 13 is concave in shape and is used for the aircraft landing gear 8 to be detachably installed therein.

[0029] The aircraft landing gear 8 has an inverted U-shaped frame structure, with a wheel 81 rotatably connected to each of its lower ends. The two wheels 81 are symmetrically arranged, allowing the paper airplane 10 to be stably supported and slide freely when placed on the ground, thus simulating the ground taxiing and takeoff process of a real aircraft. At the bottom of the main body 1, there is also a downward protruding plate 14, which is located at one edge of the landing gear groove 13. Furthermore, a protrusion 15 is provided on the plate 14, protruding towards the landing gear groove 13.

[0030] When the aircraft landing gear 8 is installed and fitted into the landing gear groove 13, the protrusion 15 just abuts against the crossbeam part of the aircraft landing gear 8 from above. The interference fit or locking action between the protrusion 15 and the aircraft landing gear 8 effectively prevents the aircraft landing gear 8 from accidentally falling out of the landing gear groove 13 due to vibration or airflow impact during flight. At the same time, when it is necessary to disassemble, the aircraft landing gear 8 can be easily removed by simply pulling it outward to overcome the resistance of the protrusion 15, thereby achieving quick replacement.

[0031] In addition, an airplane support 9 is fixedly installed on the upper part of the main body 1. The airplane support 9 has a flat structure and extends along the length of the main body 1. Its function is to serve as an intermediate connecting carrier between the paper airplane 10 body and the drive control device.

[0032] Specifically, a long groove 91 is provided in the middle of the aircraft support 9 along its length. The width of the long groove 91 matches the thickness of the folded paper airplane 10 body. It is used to allow the paper airplane 10 body, which is made of thin material such as A4 paper, to be inserted from above and locked in, thereby realizing a detachable and fixed connection between the paper airplane 10 body and the aircraft support 9.

[0033] To further improve the stability of the paper airplane 10 after installation, support bars 92 are symmetrically extended outward on both sides of the airplane support 9. The two support bars 92 are spread out horizontally, and their ends extend to the area below the wings of the paper airplane 10. When the paper airplane 10 is installed in the long groove 91, the support bars 92 on both sides support the root of the wings of the paper airplane 10 from below, effectively dispersing the aerodynamic load borne by the paper airplane 10 during flight, and preventing the paper airplane 10 from loosening from the long groove 91 or bending and deforming due to concentrated force.

[0034] The embodiments described above are merely illustrative of implementation methods of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
