[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model discloses a remote-controlled toy airplane with an airdrop function, which improves the structure of an existing remote-controlled toy airplane and adds an airdrop cargo hold to the existing remote-controlled toy airplane structure to realize the airdrop function of the remote-controlled toy airplane.

[0028] The conventional layout of the existing toy airplane includes a fuselage, wings (including ailerons and flaps), a vertical tail (including a rudder), a horizontal tail (including an elevator), a propulsion device, a signal receiving / control device, a flight controller, a steering gear, a landing gear, etc. Based on the existing toy airplane structure, the present invention reserves a rectangular airdrop cabin installation cavity in the fuselage 2 of the toy airplane for accommodating an airdrop cargo hold 1, such as Figure 1 , Figure 2 shown.

[0029] The airdrop cargo hold 1 is a storage structure for airdropped objects, including a left door 101a, a right door 101b, a cargo hold bottom support 102, a cargo hold frame 103 and a locking mechanism. Figure 3 , Figure 4 shown.

[0030] The cargo hold frame 103 is a rectangular parallelepiped structure, and its size is the same as that of the airdrop cabin installation cavity. The cargo hold frame 103 has a left frame, a right frame and a top frame, and all three have a frame body in the circumferential direction and reinforcing beams arranged at equal intervals between the two opposite sides of the frame body.

[0031] Among them, the front and rear ends of the bottom edges of the left and right frames are designed with columnar frame joints 104 integrally formed with the cargo hold frame 103, and the frame joints 104 are coaxially opened with an axial hole along the front-to-back direction for connecting the left door 101a and the right door 101b.

[0032] At the same time, a cargo hold bottom support 102 is fixedly installed between the bottom edges of the left and right frames. The cargo hold bottom support 102 is also a frame structure, and the left and right ends are respectively fixed to the bottom edges of the left and right frames. The right part of the cargo hold bottom support 102 is designed as a platform structure, and the middle part has a rectangular opening to cooperate with the locking mechanism to achieve the locking of the left door 101a and the right door 101b after closing.

[0033] The left hatch 101a and the right hatch 101b have the same structure, with a flat top surface, a side wall perpendicular to the top surface, and a bottom surface that is an arc surface connected to the side wall and the top surface. The side at the angle between the top surface and the bottom surface is a hinged side, and the front and rear parts of the hinged side are respectively designed with an integrally formed columnar hatch joint 105, and the hatch joint 105 is coaxially opened with an axis hole along the front-to-back direction, which is used for connecting the left hatch 101a, the right hatch 101b and the cargo hold frame 103.

[0034] In the above-mentioned right door 101b, an inwardly recessed rectangular groove 101c is designed at the angle between the top surface and the side surface. The rectangular groove 101c is designed along the front-to-back direction and passes through the front and rear side surfaces of the right door 101a. At the same time, in the left door 101b, a rectangular cross-section boss 101d is designed on the side surface. The boss 101d is designed along the front-to-back direction, and the top surface and the front and rear end surfaces are flush with the top surface and the front and rear side surfaces of the left door 101a, respectively, and the cross-sectional dimensions of the boss 101b are the same as the cross-sectional dimensions of the rectangular groove 101c on the above-mentioned right door 101a.

[0035] The front and rear door joints 104 of the hinged side of the left door 101a of the above structure are respectively coaxially arranged with the front and rear frame joints 105 of the bottom side of the left frame, and the ends are in contact with each other, and the rotation shaft passes through the shaft holes on the two joints in contact with each other, so as to realize the hinged connection between the left door 101a and the left frame. Similarly, the front, middle and rear door joints 104 of the hinged side of the right door 101b are respectively coaxially arranged with the front, middle and rear frame joints 105 of the bottom side of the right frame, and the ends are in contact with each other, and the rotation shaft passes through the shaft holes on the two joints in contact with each other, so as to realize the hinged connection between the right door 101b and the right frame.

[0036] When closing the two doors, the left door 101a and the right door 101b are closed in sequence until the top surface of the right door 101b contacts the bottom surface of the cargo hold bottom support 102 and the boss 101d on the left door 101a is inserted into the rectangular groove 101c on the right door 101b, and the doors are closed. At this time, the locking mechanism is used to lock the left door 101a and the right door 101b.

[0037] The locking mechanism includes a locking hook 106 and a micro unlocking motor 107 .

[0038] The lock hook 106 is an L-shaped hook structure as a whole, one side of which is perpendicular to the top surface of the right door 101b, and the end is fixedly installed on the top surface of the right door 101b, and is located in the middle of the right door 101b near the rectangular groove 101c. The other side of the lock hook 106 is a locking matching side, the top is designed as a locking inclined surface 106a for matching with the lock tongue 107a of the micro unlocking motor 107, and the bottom is a locking matching surface 106b for matching with the lock tongue 107a to achieve locking between the left door 101a and the right door 101b.

[0039] The micro unlocking motor 107 is used to lock the hatch 101 after closing and to open the hatch 101 after unlocking. It is fixedly installed on the left platform of the cargo hold bottom support 102, and the direction of the lock tongue 107a is facing the lock hook 106. When the two hatches are closed, the lock tongue 107a of the micro unlocking motor 107 is controlled to extend so that it contacts the locking mating surface 106b at the top of the lock hook 106, thereby limiting the rotation of the left hatch 101a and the right hatch 101b, thereby achieving the locking of the two hatches after closing.

[0040] The lock tongue (suction-type micro-frame electromagnet) of the above-mentioned micro unlocking motor 107 has a spring mechanism inside the lock tongue 107a, and the lock tongue 107a is in an extended state when the power is off. When the power is off and the lock tongue 107a is under pressure, the lock tongue 107a can be retracted. In addition, the lock tongue 107a will also retract after power is turned on.

[0041] The airdrop cargo hold 1 of the above structure is fixed in the airdrop cabin installation cavity by gluing or screwing, and when the two doors are closed, the bottom surfaces of the left door 101a and the right door 101b are conformal to the outer surface of the fuselage to reduce flight resistance. Figure 5 , Figure 6 As shown, a torsion spring installation box 108 is also designed in the middle of the bottom edge of the left frame of the cargo hold frame 103, and a retractable torsion spring 109 is arranged in the torsion spring installation box 108. Both ends of the retractable torsion spring 109 pass through the torsion spring installation box 108, one end is fixedly connected to the left frame, and the other end is clamped and fixed between the inner wall of the airdrop cabin installation cavity and the outer wall of the cargo hold frame 103. Similarly, a retractable torsion spring 109 is installed on the bottom edge of the right frame in the same way. Thus, through the elastic force of the retractable torsion spring 109, the left door 101a and the right door 101b are automatically opened after being unlocked.

[0042] The hatch door opening and closing control in the above-designed airdrop cargo hold 1 is controlled by adding a control channel in the flight controller of the existing toy airplane to control the micro unlocking motor 107. When the airplane is flying, the user can send an airdrop command through the flight controller, and the signal receiving / control device further controls the locking tongue 107a of the micro unlocking motor 107 to retract after receiving the command. The hatch door opens under the action of gravity and the retractable torsion spring 109, and the airdropped objects 4 in the airdrop cargo hold 1 automatically fall out. Figure 7 As shown. After the user loads the airdrop 4, the left door 101a is closed first, and then the right door 101b is closed, so that the boss 101d on the left door 101a is embedded in the groove 101c on the right door 101b, and the left door 101a is pressed by the right door 101b. When the right door 101b is closed at the same time, the top locking inclined surface 106a of the lock hook 106 on the right door 101b contacts the lock tongue 107a, and the lock tongue 107a further moves and compresses along the inclined surface 106a until the top of the lock hook 106 is separated from the lock tongue 107a, and the lock tongue 107a pops out to the bottom of the lock matching side 106b of the lock hook 106, and the lock tongue 107a cooperates with the bottom surface of the lock matching side 106b to limit the rotation of the right door 101b. At this time, the two doors are closed in place, and the loading of the airdrop 4 is completed.
