[0028] Please refer to Figures 1 to 6 This embodiment provides a detachable wing structure of a model airplane toy, including a fuselage 100 and wings 200 detachably connected to the fuselage 100. The fuselage 100 is provided with an inner cavity 110 for fixing and installing a control circuit structure such as a battery and a circuit board. The inner cavity 110 is connected to the outside through an inner cavity opening. A hatch 300 is detachably adapted to be connected to the inner cavity opening. The inner cavity 110 can be opened or closed by connecting or detaching the hatch 300 to the inner cavity opening, so as to facilitate the disassembly and subsequent maintenance of the control circuit structure.

[0029] A detachable frame 120 is fixedly attached to the fuselage 100 adjacent to the inner cavity opening. It is understood that a positioning plate for the detachable frame 120 is exposed on one side of the inner cavity opening. This positioning plate is connected to the hatch 300 in a manner that allows one end of the hatch 300 to be detachably connected to the inner cavity opening. A recessed slot 111 is provided on the other side of the inner cavity opening. This slot 111 is detachably plugged into and fixed to the hatch 300, allowing the other end of the hatch 300 to be similarly detachably connected to the inner cavity opening.

[0030] The detachable frame 120 includes an outer frame 121 fixed to the fuselage 100 and an inner frame 122 fixed to the outer frame 121. The outer frame 121 has two through-holes and a bottom with a first through-hole 1211 communicating with the inner cavity 110. The first through-hole 1211 allows the conductive wires of the control circuit structure to pass through and enter the detachable frame 120. It will be understood that fixing posts 1212 are respectively provided on both sides of the outer wall of the outer frame 121 at positions directly opposite the connecting posts of the inner frame 122. The fixing posts 1212 on the same side of the outer frame 121 have countersunk holes for receiving screws, which can be used to securely connect the inner frame 122 to the outer frame 121. The outer frame 121 is also provided with an adhesive plate 1214, which is planar and annularly arranged around the outer periphery of the outer frame 121. Adhesion plate 1214 is adhesively fixed to the interior of the fuselage 100, ensuring a more secure and stable connection between the fuselage 100 and the detachable frame 120. A positioning plate 1215 is perpendicularly mounted on the adhesive plate 1214, at least partially extending outside the fuselage 100. Specifically, a portion of positioning plate 1215 is exposed on one side of the inner cavity opening. Positioning plate 1215 is designed to engage with the elastic U-shaped buckle of the hatch cover 300, thereby preventing it from tilting upward away from the inner cavity opening.

[0031] In this embodiment, the inner frame 122 includes a first frame 1221 and a second frame 1222, each of which includes a chamber 1230. In other words, the inner frame 122 is provided with two chambers 1230 on either side of the outer frame 121. The two chambers 1230 are connected to the first through-hole 1211 via a second through-hole 1231, allowing the conductive wires of the control circuit structure to pass through the second through-hole 1231 and enter the two chambers 1230. It is understood that at least one fixing portion is provided on each side where the first frame 1221 and the second frame 1222 meet, each of which includes a connecting column 1223 and a clearance groove 1224 arranged adjacent to each other in the vertical direction. The connecting column 1223 of the first frame 1221 is placed in the clearance groove 1224 connected to the second frame 1222, so that the connecting columns 1223 of the first frame 1221 and the second frame 1222 and the fixing columns 1212 on both sides of the outer frame 121 can be placed on the same axis and fixed together by the screws, thereby enabling the first frame 1221 and the second frame 1222 to be fixed in an adjacent arrangement within the outer frame 121. It should be noted that splitting the inner frame 122 into a combination of the first frame 1221 and the second frame 1222 can help simplify the production process and save production costs. In other embodiments of the present invention, the inner frame 122 can be formed as a single piece. In this case, only the connecting column 1223 is provided in the inner frame 122 relative to the fixing column 1212.

[0032] In this embodiment, a first positioning post 1225 protrudes from the sidewall of the first frame 1221 toward the second frame 1222. A corresponding second positioning post 1226 is provided on the sidewall of the second frame 1222 to accommodate the first positioning post 1225, facilitating quick positioning and connection between the first frame 1221 and the second frame 1222. The second positioning post 1226 protrudes from the cavity 1230 of the second frame 1222 and can be removably inserted into the insertion section fixed to the wing 200, further enhancing the stability and securement of the connection of the wing 200 within the cavity 1230. In other embodiments of the present invention, the first and second frames 1221, 1222 may not be provided with the first and second positioning posts 1225, 1226.

[0033] As can be understood, the inner wall of each chamber 1230 is raised from the inside outward to form a first insert block 1232 and a second insert block 1233. The first insert block 1232 is provided with a first insertion hole 1234 for communication with the outside world, while the second insert block 1233 is provided with a second insertion hole 1235 for communication with the outside world and the second through hole 1231. In this embodiment, the height of the first insert block 1232 is greater than that of the second insert block 1233, which is less than the depth of the second groove in the wing 200. Furthermore, the inner frame 122 also includes a third through hole 1236, which is located on the sidewall between the two chambers 1230, opposite the second insertion hole 1235 and communicating with the second through hole 1231. It should be noted that the unequal heights of the first and second insert blocks 1232, 1233 facilitate the user's ability to correctly insert and secure the wing 200 into the corresponding chamber 1230. The unequal heights of the second insert 1233 and the second groove, as well as the provision of the third through hole 1236, allow the conductive wires of the control circuit structure to be arranged in a relatively reasonable and orderly manner, facilitating subsequent maintenance operations. In other embodiments of the present invention, the first insert 1232 and the second insert 1233 can be arranged at the same height, and the second insert 1233 can also be arranged at the same height as the second groove. In this case, the sidewall between the two chambers 1230 may optionally be provided with the third through hole 1236.

[0034] There are two wings 200, each comprising an integrally formed insertion section 210 and wing section 220. The insertion section 210 is removably adapted to be inserted into the cavity 1230. A first slot 211 matching the shape of the first insert block 1232 and a second slot 212 matching the shape of the second insert block 1233 are recessed within the insertion section 210. It will be appreciated that, because the arrangement of the connecting posts 1223 results in a correspondingly shaped protrusion within each cavity 1230, a third slot 213 matching the shape of the protrusion is also recessed within the insertion section 210. Furthermore, because the second positioning post 1226 protrudes into one of the cavities 1230, a fourth slot 214 matching the shape of the second positioning post 1226 is also recessed within the insertion section 210 of one of the wings 200.

[0035] As will be understood, the wing section 220 is provided with a rudder plate 221 and a fixing slot 222. The rudder plate 221 is pivotally connected to the wing section 220. A servo 230 is fixedly mounted within the fixing slot 222. The swing arm 231 of the servo 230 is linked to the rocker 2211 of the rudder plate 221 via a connecting rod. This arrangement enables the servo 230 to swing the rocker 2211 by swinging the swing arm 231, causing the rudder plate 221 to swing on the wing section 220. By adjusting the angle of the rudder plate 221, the flow state of the airflow on either side of the wing 200 is differentiated, thereby enabling the model aircraft to be steered in a desired direction. Wing section 220 is further provided with a first groove 223 and a second groove 224. An insert 240 is embedded in first groove 223. Insert 240 extends into first slot 211 and is removably inserted and fixed into first receptacle 1234. Second groove 224 communicates with second slot 212 and is connected to second receptacle 1235. In other words, when insertion section 210 of wing 200 is inserted into corresponding cavity 1230, first insert 1232 is inserted into first slot 211, insert 240 is inserted into first receptacle 1234, second insert 1233 is inserted into second slot 212, and second groove 224 is connected to second receptacle 1235. At the same time, the second groove 224 is connected to the fixing groove 222, so that the conductive wire of the servo 230 can be received in the second groove 224 and can enter the inner cavity 110 through the second plug hole 1235, the second through hole 1231 and the first through hole 1211 in sequence, thereby realizing the electrical connection between the servo 230 and the control circuit structure.

[0036] It should be noted that in other embodiments of the present invention, a light-emitting diode can also be fixedly installed in the fixing groove 222. At this time, the conductive wire of the light-emitting diode can also be placed in the second groove 224 and can pass through the third through hole 1236, the second through hole 1231 and the first through hole 1211 in sequence into the inner cavity 110, thereby realizing the electrical connection between the light-emitting diode and the control circuit structure.

[0037] One end of the hatch cover 300 is provided with a latch block 310 that is detachably engaged with the latch slot 111. The other end of the hatch cover 300 is provided with an elastic U-shaped buckle 320. The movable end of the elastic U-shaped buckle 320 is provided with a retaining foot 321 that engages and contacts the positioning plate 1215. The movable end of the elastic U-shaped buckle 320 can movably extend from the hatch cover 300. As will be appreciated, due to the elasticity of the elastic U-shaped buckle 320, the elastic force of the elastic U-shaped buckle 320 allows it to remain in the position where the retaining foot 321 engages and contacts the positioning plate 1215, thereby securing one end of the hatch cover 300 to the inner cavity opening. To open the hatch cover 300, the elastic U-shaped buckle 320 is pushed to move the retaining foot 321, separating it from the positioning plate 1215. The end of the hatch cover 300 is then pulled to separate from the inner cavity opening.

[0038] In summary, the detachable wing structure provided in this embodiment comprises a multi-connection structure between the detachable frame 120 and the wing 200, comprising a cavity 1230 and an insertion section 210, an insert block and slot, a positioning post and slot, an insert strip 240, and a first insertion hole 1234. This structure enables a relatively stable and secure connection of the wing 200 to the fuselage 100. Furthermore, this multi-connection structure offers the advantages of simple, convenient, and quick assembly and disassembly, eliminating the need for additional tools when installing or removing the wing 200, thereby enhancing the ease of installation and removal of the wing 200. Furthermore, the detachable wing structure further comprises a channel structure between the detachable frame 120 and the wing 200, comprising a first through hole 1211, a second through hole 1231, a third through hole 1236, a second insertion hole 1235, and a second groove 224. This channel structure connects the wing 200 to the inner cavity 110, facilitating the concealment of conductive wires and enhancing the aesthetics of the model aircraft toy.

[0039] For clarity, certain features of the present invention described in the context of separate embodiments may be combined in a single embodiment. Furthermore, various features of the present invention described in the context of a single embodiment may also be used individually or in any suitable subcombination.
