[0037] Please refer to Figures 1 to 10This embodiment provides a toy airplane structure, including a fuselage 100, a power assembly 200 and an adjustment assembly 300. The fuselage 100 includes an integrally arranged fuselage 110, wings 120 and a horizontal tail 130. The fuselage 100 is also detachably connected with a vertical tail 140. Since the detachable structure between the vertical tail 140 and the fuselage 110 adopts an existing structure, it is not described here. The power assembly 200 and the adjustment assembly 300 are respectively fixedly mounted on the fuselage 100. The power assembly 200 is used to increase the flight power of the fuselage 100. The adjustment assembly 300 is connected to the tail rudder of the horizontal tail 130 in a transmission manner, and is used to control the tail rudder to be able to perform deflection movement on the horizontal tail 130, thereby achieving the purpose of adjusting the flight attitude of the toy airplane.

[0038] Among them, the fuselage 110 is provided with an inner cavity 111, an extension plate 112 and a first mounting seat 113. The inner cavity 111 runs through the middle of the fuselage 110 to the tail along the central axis, and the extension plate 112 extends outward along the through hole of the inner cavity 111. A bottom plate is fixedly connected to the inner cavity 111 and the extension plate 112, and a mounting hole 114 is formed between the bottom plate and the extension plate 112. It can be understood that the inner cavity 111 includes a first inner cavity 1111 and a second inner cavity 1112 that are connected, and the bottom plate includes a first bottom plate 150 and a second bottom plate 160. The first bottom plate 150 is fixed to the cavity opening of the first inner cavity 1111, and the second bottom plate 160 is fixed to the cavity opening of the second inner cavity 1112 and the extension plate 112. The cooperation between the first bottom plate 150 and the second bottom plate 160 and the first inner cavity 1111 and the second inner cavity 1112 can form a relatively closed installation space in the fuselage 110. The battery 210 and the main control board 220 of the power assembly 200 are fixedly installed in the first inner cavity 1111. The battery 210 and the main control board 220 are electrically connected to form an electric control circuit with the propeller of the power assembly 200 and the adjustment assembly 300. The second inner cavity 1112 is connected to the threading groove 122 of the wing 120, and the fixing plate 170 is fixedly installed in the second inner cavity 1112. The fixing plate 170 is provided with a rear wheel groove 171 for detachably installing the rear wheel frame 600 on the fuselage 110.

[0039] It is understandable that the cooperation between the extension plate 112 and the second bottom plate 160 can facilitate the formation of a mounting hole 114 at the tail of the fuselage 110. There are two first mounting seats 113 and the two first mounting seats 113 are relatively arranged on both sides of the extension plate 112. The mounting holes 114 and the first mounting seats 113 are used to detachably mount different components of the adjustment assembly 300, so that the purchaser can customize different structures installed on the fuselage 100 according to his own ideas to achieve different flight functions.

[0040] It can be understood that a fixing cover 180 is detachably connected to each first mounting seat 113. A clamping groove 115 is formed between the fixing cover 180 and the first mounting seat 113 to facilitate the fixed installation of the swing rod sleeve or the connecting shaft sleeve of the adjusting assembly 300 on the first mounting seat 113. Each first mounting seat 113 is provided as a boss protruding outward from the fuselage 110, and the boss can be inserted and fixed in the fixing cover 180. At least one first clamping groove 1131 is formed on the outer side of the boss. The first clamping groove 1131 is slidably engaged with the fixing cover 180 in a concave-convex manner to prevent the fixing cover 180 from rotating left and right on the boss, playing a role in limiting and increasing the connection strength between the two. A notch 1132 is formed at a position of the boss flush with the extension plate 112. An installation position 1133 for rotatably connecting the swing rod sleeve or the connecting shaft sleeve is formed on the notch 1132. A receiving groove 1134 is formed by the side wall of the installation position 1133 recessing inwardly towards the fuselage 110. The swing rod of the swing rod sleeve can be received in the receiving groove 1134 to form a movable space in the clamping groove 115, enabling the swing rod of the swing rod sleeve to swing left and right in the clamping groove 115.

[0041] Correspondingly, each fixing cover 180 can be inserted and fixed on the boss. A first clamping block 181 that is slidably engaged with the first clamping groove 1131 in a concave-convex manner is provided on the inner wall of the fixing cover 180. An indented hole 182 for receiving the swing rod is formed on the fixing cover 180 corresponding to the receiving groove 1134. The indented hole 182, the receiving groove 1134, and the installation position 1133 constitute the clamping groove 115. A through hole 183 through which the first rotating shaft and the second rotating shaft of the adjusting assembly 300 can pass is also formed on the fixing cover 180. The through hole 183 and the installation hole 114 are located on the same straight line.

[0042] The number of wings 120 is two, and the two wings 120 are oppositely arranged on both sides of the fuselage 110. A second mounting seat 121 is provided on each wing 120. The second mounting seat 121 is connected to the second inner cavity 1112 through a wire slot 122. It can be understood that the second mounting seat 121 is provided as a groove extending inward from the side of the wing 120, and the groove is connected to the wire slot 122. Limiting steps 1211 are formed by the two sides of the groove sinking. A second clamping groove 1212 is recessed on each limiting step 1211, and the propeller 230 of the power assembly 200 can be inserted and fixed in the second clamping groove 1212.

[0043] The number of the horizontal stabilizers 130 is two, and the two horizontal stabilizers 130 are oppositely arranged on both sides of the fuselage 110. Each horizontal stabilizer 130 is rotatably provided with a rudder 131 through a connecting broken line 132. The rudder 131 is fixed to the second rotating shaft of the adjusting assembly 300 and can be controlled by it to rotate up and down along the connecting broken line 132. It can be understood that the connecting broken line 132, the mounting hole 114, the mounting position 1133 and the through hole 183 are located on the same straight line, which is used to enable the adjusting assembly 300 to stably drive the rudder 131 to rotate, and at the same time has the function of a compact structure. Each rudder 131 is provided with a mounting notch 1311 at a position adjacent to the connecting broken line 132, and the mounting notch 1311 is used to fixedly connect the second rotating shaft of the adjusting assembly 300.

[0044] It can be understood that the first bottom plate 150 is a plate-like structure and is adhesively fixed to the orifice of the first inner cavity 1111. Two cavity grooves 151 communicating with the first inner cavity 1111 are opened on the first bottom plate 150. Each cavity groove 151 is provided with a mounting hole position for detachably mounting the servo of the adjusting assembly 300, so that one or two of the servos can be selectively fixed in the two cavity grooves 151. Snap holes 152 for detachably connecting the sealing cover 190 are further provided on both sides of one of the cavity grooves 151. Elastic snaps 191 are respectively arranged on both sides of the sealing cover 190, and the elastic snaps 191 can be elastically snap-connected into the snap holes 152. It can be understood that when only one servo needs to be installed on the fuselage 110, the sealing cover 190 can be hermetically connected to the other cavity groove 151, so as to form a relatively closed installation space in the fuselage 110, which can prevent objects such as dust and liquid from entering the first inner cavity 1111 from the orifice of the cavity groove 151 and affecting the normal operation of the toy airplane. It should be noted that the snap holes 152 are opened in the cavity groove 151 arranged on the same side as the battery 210 among the two cavity grooves 151, that is to say, the sealing cover 190 is detachably fixed to the orifice of the cavity groove 151 arranged on the same side as the battery 210. When only one servo is installed on the fuselage 110 as described above, the servo can be installed on the other side opposite to the battery 210, so that the overall weight distribution on the fuselage 110 can be relatively dispersed, preventing the overall weight from tilting to one side, so as to ensure that the center of gravity of the toy airplane can be maintained at a relatively central position, which is beneficial to flight.

[0045] The first bottom plate 150 is provided with a battery cover 153 at a position corresponding to the battery 210. One end of the battery cover 153 is rotatably connected to the first bottom plate 150 and the other end is detachably connected to the first bottom plate 150. That is to say, the battery cover 153 is detachably connected to the first bottom plate 150. By means of the battery cover 153, it is convenient to replace the battery 210, and thus the use of the toy plane is facilitated. In this embodiment, heat dissipation holes 1531 and bracket mounting holes 1532 are formed in the battery cover 153. The heat dissipation holes 1531 facilitate the heat dissipation of the battery 210. A support frame 400 is detachably inserted and fixed in the bracket mounting holes 1532. The support frame 400 is used to support the body 100 above the ground on a plane. The cooperation between the bracket mounting holes 1532 and the support frame 400 enables the purchaser to choose to install or remove the support frame 400 on the body 100. When the support frame 400 is connected to the body 100, the structure of the toy plane can be used as an airplane ornament for viewing. It can be understood that an insertion block 410 corresponding to the shape of the bracket mounting holes 1532 is provided on the support frame 400. The support frame 400 can be inserted and fixed in the bracket mounting holes 1532 or detached from the bracket mounting holes 1532 through the insertion block 410. In other embodiments of the present utility model, the bracket mounting holes 1532 may not be provided on the battery cover 153, and then the body 100 can only touch the ground through the front wheel frame 500 and the rear wheel frame 600.

[0046] A front wheel groove 154 is further formed in the first bottom plate 150. A front wheel frame 500 is detachably inserted and fixed in the front wheel groove 154. Among them, the front wheel frame 500 includes a first bracket 510 and a front wheel 520 rotatably connected to one end of the first bracket 510. It can be understood that a first plug connector 511 is formed at the other end of the first bracket 510. The shape of the first plug connector 511 is adapted to the front wheel groove 154 and is detachably inserted and fixed in the front wheel groove 154. Through the cooperation between the front wheel groove 154 and the first plug connector 511, the front wheel frame 500 is detachably connected to the fuselage 110, so that the purchaser can choose to install or remove the front wheel frame 500 on the body 100.

[0047] It can be understood that the second bottom plate 160 is of a block structure and is inserted and fixed in the second inner cavity 1112. A step 161 is provided on the second bottom plate 160 opposite to the first bottom plate 150, and the first bottom plate 150 is adaptively connected to the step 161, so that the second bottom plate 160 can be more firmly connected to the second inner cavity 1112 under the limiting action of the first bottom plate 150. It should be noted that, in order to enable the second bottom plate 160 to be further firmly connected to the second inner cavity 1112, the second bottom plate 160 can also be adhesively connected to the second inner cavity 1112. A through channel 162 is provided in the second bottom plate 160 corresponding to the positions of the first inner cavity 1111 and the wire groove 122. The through channel 162 is used for the wires in the wire groove 122 to pass through and enter the first inner cavity 1111. A through hole 163 is provided in the second bottom plate 160 corresponding to the rear wheel groove 171. The rear wheel groove 171 is detachably plugged and fixed with a rear wheel frame 600 through the through hole 163. Among them, the rear wheel frame 600 includes a second bracket 610 and rear wheels 620 rotatably connected to both ends of the second bracket 610. It can be understood that a second plug joint 611 is formed in the middle of the second bracket 610. The shape of the second plug joint 611 is adapted to the rear wheel groove 171 and is detachably plugged and fixed in the rear wheel groove 171 through the through hole 163. Through the cooperation of the through hole 163, the rear wheel groove 171 and the rear wheel frame 600, the rear wheel frame 600 is detachably connected to the fuselage 110, so that the user can choose to install or remove the rear wheel frame 600 on the body 100.

[0048] The power assembly 200 further includes a propeller 230, and the propellers 230 are fixedly installed on the second mounting seats 121 of the wing 120 in a one-to-one correspondence. It can be understood that each propeller 230 includes an outer housing 231, a motor 232 inserted and fixed in the outer housing 231, a fan blade 233 fixed on the output shaft of the motor 232, and a light-emitting body 234 connected to the other end of the outer housing 231 relative to the fan blade 233. Among them, the outer housing 231 is a cylindrical structure with both ends penetrating, and it is adaptively connected to the groove. The outer housing 231 is provided with a flank 2311 matching the limit step 1211, and a second clamping block 2312 protruding from the flank 2311 and inserted and matched with the second clamping groove 1212. Through the cooperation of the second clamping block 2312 and the second clamping groove 1212, the outer housing 231 is detachably and fixedly connected to the second mounting seat 121. It should be noted that in order to further increase the connection strength between the two, the flank 2311 can be adhesively connected to the limit step 1211. It should be noted that the motor 232 is electrically connected to the main control board 220 through a wire, and the wire is received in the wire groove 122 and accesses the main control board 220 in the first inner cavity 1111 through the through channel 162. The fan blade 233 extends out of the wing 120 and is used to rotate when the motor 232 is started, so as to provide flight power for the aircraft body 100. The light-emitting body 234 is clamped and fixed between the inner wall of the outer housing 231 and the second mounting seat 121 and is externally disposed on the outer housing 231. The light-emitting body 234 is used to emit light when the motor 232 is started, so as to play a role in prompting the position and working state of the propeller 230.

[0049] The adjustment assembly 300 includes a servo 310, a first rotating shaft 320 and a second rotating shaft 330. Among them, the servo 310 is detachably installed in a cavity 151. It can be understood that the number of servos 310 can be set to one or two according to the needs of the purchaser. Each servo 310 can be detachably connected to the mounting hole position in any cavity 151 through a threaded part. Furthermore, one servo 310 (and the sealing cover 190) or two servos 310 can be fixedly installed in the two cavities 151.

[0050] The first rotating shaft 320 is detachably slidably fitted in the mounting hole 114, and the second rotating shaft 330 is fixedly connected to the tail rudder 131 in a one-to-one correspondence. It can be understood that each second rotating shaft 330 includes a vertically fixed mounting plate 331 and a fixed shaft 332. The mounting plate 331 has the same shape as the mounting notch 1311 and is fixedly connected in the mounting notch 1311, and the fixed shaft 332 is circumferentially fixed to the rocker sleeve 340 or the connecting sleeve 350. The two second rotating shafts 330 can be coaxially fixed with the first rotating shaft 320 through the rocker sleeve 340 and the connecting sleeve 350, or the two second rotating shafts 330 can be connected to the first mounting seat 113 through the rocker sleeve 340 respectively. The rocker sleeve 340 and the connecting sleeve 350 can both be rotatably installed in the clamping groove 115, and are both restricted by the fixing cover 180 and stably connected to the first mounting seat 113. The swing arm sleeve 340 is rigidly connected to the swing arm of a steering gear 310 through the connecting rod 360, so that when the swing arm of the steering gear 310 swings left and right, the swing arm sleeve 340 can be driven to swing left and right through the connecting rod 360, so that the swing arm sleeve 340 can drive the second rotating shaft 330 to rotate and drive the tail rudder 131 to swing up and down. The swing arm sleeve 340 and the connecting sleeve 350 can both fix the second rotating shaft 330 to the first rotating shaft 320, so that the first rotating shaft 320 and the two second rotating shafts 330 can be combined into a fixed rotating shaft.

[0051] When assembling the toy airplane structure, the purchaser first fixes the propeller 230 on the second mounting seat 121 so that its wires can enter the second inner cavity 1112 and the first inner cavity 1111 through the threading groove 122, and then installs the battery 210 and the main control board 220 in the first inner cavity 1111 so that the wires can be electrically connected to the main control board 220. Then, the fixing plate 170 is fixedly installed in the second inner cavity 1112, and the second bottom plate 160 is fixedly installed on the cavity opening of the second inner cavity 1112, and the first bottom plate 150 is fixedly installed on the cavity opening of the first inner cavity 1111, and the installation of the power assembly 200 is completed. At this time, the toy airplane structure can only realize the straight flight function.

[0052] When it is necessary to enable the toy plane to have both a straight flight function and a pitch flight function, another servo 310 and a corresponding rotating shaft structure need to be installed on the fuselage 100. At this time, the servo 310 needs to be fixed in the cavity 151 without the buckle hole 152, and the sealing cover 190 needs to be connected to the other cavity 151 by buckling. Subsequently, the fixing cover 180 is detached from the first mounting seat 113, and then the first rotating shaft 320 is inserted into the mounting hole 114 so that the two are slidably matched. The two second rotating shafts 330 are fixedly connected to the tail rudder 131 one by one. A swing rod bushing 340 is fixed on the second rotating shaft 330 on the same side as the servo 310, and a connecting bushing 350 is fixed on the second rotating shaft 330 on the same side as the sealing cover 190. The swing rod bushing 340 and the connecting bushing 350 are respectively connected in the two first mounting seats 113. At this time, the first rotating shaft 320 fixedly connects the two second rotating shafts 330 through the swing rod bushing 340 and the connecting bushing 350. Finally, the fixing cover 180 is fixedly installed on the first mounting seat 113, and the installation of a servo 310 and its corresponding rotating shaft structure can be completed. When the servo 310 works, its swing arm can drive the swing rod bushing 340 to rotate through the connecting rod 360. Since the first rotating shaft 320 fixedly connects the two second rotating shafts 330 through the swing rod bushing 340 and the connecting bushing 350, the other second rotating shaft 330 can be driven to rotate in the same direction at the same time, so that the two tail rudders 131 rotate in the same direction, thereby realizing the pitching motion of the horizontal tail 130.

[0053] When it is necessary to enable the toy plane to have a straight flight function, a pitch flight function and a yaw flight function at the same time, two servos 310 and corresponding rotating shaft structures need to be installed on the fuselage 100. At this time, the two servos 310 need to be fixedly corresponding to the two cavities 151. Subsequently, the fixing cover 180 is detached from the first mounting seat 113, and swing rod bushings 340 are fixed on both of the two second rotating shafts 330. The two swing rod bushings 340 are respectively connected in the two first mounting seats 113. Finally, the fixing cover 180 is fixedly installed on the first mounting seat 113, so that the two second rotating shafts 330 are respectively rotatably connected to the fuselage 110 through the swing rod bushings 340, and the installation of the two servos 310 and their corresponding rotating shaft structures can be completed. The two servos 310 can respectively drive the corresponding swing rod bushings 340 to rotate through the connecting rods 360, so as to drive the two tail rudders 131 to deflect in the same direction to realize the pitching motion of the horizontal tail 130, and can also drive the two tail rudders 131 to deflect differentially to realize the yaw motion of the horizontal tail 130.
