Description

Technical Field

[0001] This invention relates to the field of drone technology, and in particular to a detachable wing for a children's drone. Background Technology

[0002] Developing children's hands-on skills from a young age is crucial for enhancing their intellectual development. Drones, as a popular and increasingly accessible technology, have become more affordable with age. Drones that can be assembled and modified, in particular, offer a significant challenge to children's practical and problem-solving abilities.

[0003] Currently, there are various child-friendly assembly drones on the market, allowing children to assemble and fly them. However, the inventors discovered during their use of these drones that the assembly process is not child-friendly. The wings are often made of metal, which is quite sharp, frequently causing finger cuts during wing assembly and disassembly. This is especially true if the power is forgotten during improper operation, as the wings can rotate momentarily during assembly, potentially injuring fingers. Summary of the Invention

[0004] This invention provides a detachable wing for a child-friendly drone, making it more suitable for children and providing protection for fingers or other parts of the body during wing assembly.

[0005] A detachable wing for a children's drone includes a motor, a propeller, and landing gear, wherein the propeller is mounted on the output shaft of the motor; it also includes a quick-connect power plug.

[0006] The quick-connect power plug is equipped with a female terminal for connecting to the drone fuselage.

[0007] The landing gear includes outriggers, terminal blocks, and propeller stops;

[0008] The quick-connect power plug has a recessed hole on its side wall, and the top of the support leg has two connecting plates for clamping the quick-connect power plug. The inner side wall of the connecting plate has a protrusion that matches the recessed hole. When the protrusion is fitted into the recessed hole, the support leg can rotate about the protrusion as an axis.

[0009] The terminal baffle is installed on the top side wall of the support leg. When the support leg is rotated to an angle of 180° with the quick-connect power plug, the terminal baffle will block the female terminal of the wiring terminal.

[0010] The propeller stop is vertically mounted on the top side wall of the support leg. When the support leg rotates to a 90° angle with the quick-connect power plug, the propeller stop blocks the rotation direction of the propeller. The height of the support leg is less than 10cm; the length of the propeller is greater than the length of the support leg, and the ratio of the propeller length to the support leg length is 1:0.3-0.5; the length of the propeller stop is less than the length of the support leg; it also includes a protection button for cutting off the power supply to the motor; the protection button is located on the rotation trajectory of the support leg; when the support leg rotates to a 90° angle with the quick-connect power plug, the support leg presses the protection button, thus cutting off the power to the motor.

[0011] The quick-connect power plug has a motor compartment, and the motor is installed inside the motor compartment. The output end of the quick-connect power plug is connected to the motor via a wire, which passes through the inner wall of the motor compartment and connects to the motor.

[0012] The terminal baffle is made of rubber; it also includes a fixing and positioning component, with fixing plates at both ends of the fixing and positioning component; the quick-connect power plug and the support leg are respectively provided with fixing slots that cooperate with the fixing plates; when the fixing plate is inserted into the fixing slot, the fixing and positioning component fixes the support leg to the quick-connect power plug.

[0013] The propeller stop is made of stainless steel and its outer surface is covered with a cushioning rubber layer.

[0014] The support leg is provided with two fixing slots that cooperate with the fixing plate, so that the fixing and positioning component can be fixedly installed on the support leg.

[0015] The legs are made of aluminum alloy and have several perforated holes on their surface.

[0016] The thickness of the terminal baffle is less than 1.5 mm.

[0017] The motor compartment is made of metal, and its surface is uniformly provided with heat dissipation holes.

[0018] This invention provides a detachable wing for a child-friendly drone. The overall structure is simple. Through the cooperation of a quick-connect power plug, outriggers, terminal baffles, and propeller levers, the propeller levers will block the wing when the child is attaching it, preventing the wing's self-rotation from causing excessive harm to the child.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] Please refer to Figure 1-4 This invention provides a detachable wing for a child-friendly drone, comprising a motor 1, a propeller 2, landing gear 3, and a quick-connect power plug 4. The propeller 2 is mounted on the output shaft of the motor 1. The motor 1 drives the propeller 2 to rotate. The rotation of the propeller 2 causes the drone to take off. The landing gear 3 helps the drone maintain a certain height above the ground, facilitating takeoff and preventing scratches to the drone's fuselage during landing.

[0026] The quick-connect power plug 4 has a female terminal 5 for connecting to the drone fuselage. The female terminal 5 is used to connect to the drone fuselage, thereby enabling the chip on the drone to control the speed or start / stop of the motor 1.

[0027] The landing gear 3 includes outriggers 31, terminal baffles 32, and propeller stop 33. Outriggers 31 provide support. Terminal baffles 32 cover the female connector 5 of the wiring terminal, and propeller stop 33 covers the propeller 2. The height of the outriggers is less than 10 cm; the length of the propeller is greater than the length of the outriggers, and the ratio of the propeller length to the outrigger length is 1:0.3-0.5; the length of the propeller stop is less than the length of the outriggers.

[0028] The quick-connect power plug 4 has a recessed hole on its side wall. The top of the support leg 31 has two connecting plates 34 for clamping the quick-connect power plug 4. The inner side wall of the connecting plate 34 has a protrusion that matches the recessed hole. When the protrusion is fitted into the recessed hole, the support leg 31 can rotate around the protrusion as an axis, thereby realizing the assembly of the quick-connect power plug 4 and the support leg 31.

[0029] The terminal baffle 32 is mounted on the top side wall of the support leg 31. When the support leg 31 is rotated to an angle of 180° with the quick-connect power plug 4, the terminal baffle 32 blocks the female terminal 5. Therefore, the female terminal 5 cannot be installed onto the drone body at this time.

[0030] The propeller stop bar 33 is vertically mounted on the top side wall of the support leg 31. When the support leg 31 rotates to an angle of 90° with the quick-connect power plug 4, the propeller stop bar 33 blocks the rotation direction of the propeller 2, preventing the propeller 2 from rotating.

[0031] Therefore, during use, it can be ensured that when the detachable wing needs to be installed on the drone fuselage, the support leg 31 must first be rotated to an angle of 90° with the quick-connect power plug 4. At this time, the terminal baffle 32 is away from the terminal female 5, exposing the terminal female 5. Since the propeller stop 33 blocks the rotation direction of the propeller 2, the propeller 2 cannot rotate, ensuring that the propeller 2 will not be continuously rotated after sudden power-on, causing unpredictable harm to children. When the detachable wing is installed on the drone fuselage, the support leg 31 can be rotated to an angle of 180° with the quick-connect power plug 4. It also includes a protection button 300 for cutting off the motor power supply; the protection button 300 is located on the rotation trajectory of the support leg 31; when the support leg 31 rotates to an angle of 90° with the quick-connect power plug 4, the support leg 31 presses the protection button, cutting off the power to the motor 1.

[0032] To ensure that the terminal baffle 32 does not obstruct the rotation of the support leg 31, the terminal baffle 32 is further made of rubber. Because rubber is flexible and deformable, it will not prevent the support leg 31 from becoming unable to rotate when rotated. However, bending the rubber will cause the support leg 31 to rotate in the opposite direction; therefore, a fixing and positioning member 35 is also provided.

[0033] The fixed positioning member 35 is provided with fixed insert plates 36 at both ends; the quick-connect power plug 4 and the support leg 31 are respectively provided with fixed slots 37 that cooperate with the fixed insert plates 36; when the fixed insert plate 36 is inserted into the fixed slot 37, the fixed positioning member 35 fixes the support leg 31 to the quick-connect power plug 4, preventing the problem of the bent terminal baffle 32 causing the support leg 31 to rotate in order to restore its original shape.

[0034] In one optional embodiment, the quick-connect power plug 4 is provided with a motor compartment 41, and the motor 1 is installed inside the motor compartment 41. The output end of the quick-connect power plug 4 is connected to the motor 1 via a wire, which passes through the inner wall of the motor compartment 41 and connects to the motor 1. This prevents the wire from being exposed outside the motor compartment 41, avoiding wire wear and extending its service life.

[0035] In one optional embodiment, the propeller stop 33 is made of stainless steel to ensure that the propeller 2 will not cut off the propeller stop 33. To prevent the propeller stop 33 from damaging the propeller 2 and causing surface damage to the propeller 2 upon impact, the outer surface of the propeller stop 33 is covered with a cushioning rubber layer. The thickness of the cushioning rubber layer can be less than 1 mm.

[0036] In an optional embodiment, the support leg 31 is provided with two fixing slots 37 that cooperate with the fixing plate 36, so that the fixing positioning member 35 can be fixedly installed on the support leg 31. Thus, when it is not necessary to fix the angle of the support leg 31 and the quick-connect power plug 4, the fixing positioning member 35 can be stored on the support leg 31 to avoid loss.

[0037] In one optional embodiment, the support leg 31 is made of aluminum alloy and has several hollow holes on its surface, which not only reduces the weight of the support leg 31 but also makes it more aesthetically pleasing.

[0038] In one alternative embodiment, the thickness of the terminal baffle 32 is less than 1.5 mm in order to facilitate the deformation of the terminal baffle 32.

[0039] In one optional embodiment, the motor housing 41 is made of metal, and the surface of the motor 41 is uniformly provided with heat dissipation holes to facilitate heat dissipation of the motor 1.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
