[0025] Reference Figure 1-4 As shown, it is a preferred embodiment provided by the utility model.
[0026] The toy aircraft with a simple structure includes a shell 100 arranged in a hollow shape, the shell 100 surrounds an inner cavity, a rotatable base 101 is provided in the inner cavity, a motor and a transmission structure are provided in the base 101; an inner shaft body 400 and an outer shaft body 500 are passed through the base 101, and the outer shaft body 500 is movably mounted on the outside of the inner shaft body 400.
[0027] The shell 100 is spherical, and its hollow shape can be determined according to actual conditions. The motor synchronously drives the inner shaft 400 and the outer shaft 500 through a transmission structure.
[0028] The inner shaft body 400 and the outer shaft body 500 extend into the base 101 respectively, and the motor drives the inner shaft body 400 and the outer shaft body 500 to rotate in different directions through the transmission structure; the inner shaft body 400 is connected to the upper blades, and the outer shaft body 500 is connected to the lower blades.
[0029] The toy aircraft with a simple structure provided above has a motor driving the inner shaft body 400 and the outer shaft body 500 to rotate in different directions, thereby driving the upper blades and the lower blades to rotate in different directions, and the air generates an upward thrust, so that the toy aircraft can fly in the air; during the flight, the shell 100 can rotate relative to the inner shaft body 400, and the base 101 also rotates synchronously therewith, and its structure is simple.
[0030] In this embodiment, a light strip that rotates with the base 101 can be arranged on the base 101. In this way, when the toy aircraft is flying, the light strip rotates with the base 101, creating a cooler effect.
[0031] In this embodiment, the upper blades are located above the lower blades, and the upper blades are longitudinally movably connected to the inner shaft body 400. In this way, the upper blades can achieve self-adjustment of the flight plane angle through longitudinal interaction during the rotation process.
[0032] The upper blades 200 and the upper balance pole 201 are respectively provided on both sides of the upper blades, and the upper balance pole 201 and the upper blades 200 are arranged horizontally and tilted; the middle of the upper blades is provided with an upper connection part 202, and the upper connection part 202 is longitudinally movably connected to the inner shaft body 400.
[0033] The upper balancing rod 201 is a rod-shaped object with a counterweight at the end. When the upper blades rotate, the upper balancing rod 201 rotates in the same direction as the upper blades. It has the characteristics of fixed axis and precession, which are unique to gyroscopes. When the center of rotation moves, the spatial orientation of the rotation axis remains unchanged and the predetermined movement direction of the center of rotation remains unchanged. The upper balancing rod 201 can prevent the toy aircraft from large displacement, thereby playing a certain role in wind resistance. At the same time, it can also prevent the toy aircraft from small yaw, so that the toy aircraft moves in the horizontal direction.
[0034] In this embodiment, the upper blades are integrally formed, which greatly simplifies the structure of the upper blades and improves the assembly efficiency of the upper blades.
[0035] An inner sleeve 401 is sleeved on the inner shaft body 400, and the upper connecting part 202 is longitudinally movably connected to the inner sleeve 401. By arranging the inner sleeve 401, the longitudinal movable connection between the upper connecting part 202 and the inner shaft body 400 can be facilitated, and the disassembly or assembly of the upper blades on the inner shaft body 400 can be facilitated.
[0036] The inner sleeve 401 is provided with a clamping groove 402 with a top opening, and the middle part of the upper connecting part 202 is provided with an upper movable shaft, which is movably embedded in the clamping groove 402 through the top opening and movably connected with the inner sleeve 401. After the upper movable shaft is movably embedded in the clamping groove 402, the upper blade can swing within a set range in the longitudinal direction relative to the inner shaft body 400, so that the upper blade can be self-adjusted during the rotation process.
[0037] In this embodiment, the inner sleeve 401 may extend upward and be rotatably connected to the top of the shell 100, and the bottom of the inner shaft body 400 may extend to the bottom of the base 101 and be rotatably connected to the bottom of the shell 100, thereby achieving the effect of the rotatable arrangement of the shell 100.
[0038] Alternatively, the bottom of the inner shaft body 400 extends to the bottom of the base 101 and is rotatably connected to the bottom of the shell 100; the top of the inner shaft body 400 extends to the top of the base 101 and is rotatably connected to the top of the shell 100, thereby realizing the rotational arrangement of the shell 100.
[0039] In this embodiment, the lower blades 300 are respectively provided on both sides of the lower blades, the middle of the lower blades has a lower connecting portion 301, the outer shaft body 500 passes through the lower connecting portion 301 and is fixedly connected to the lower connecting portion 301, and rotates with the rotation of the outer shaft body 500.
[0040] Alternatively, there are lower balance bars on both sides of the lower blades, and the lower connecting portion 301 is longitudinally movably connected to the outer shaft body 500. In this way, the lower blades can self-adjust in the longitudinal direction during rotation, and the lower balance bar is configured to further improve the flight stability of the toy aircraft.
[0041] The function and structure of the lower balance bar here are consistent with those of the upper balance bar 201. The lower blades are integrally formed, which facilitates the forming of the lower blades and the assembly of the lower blades on the outer shaft 500.
[0042] In this embodiment, an outer shaft sleeve 700 is sleeved on the outer shaft body 500, and two grooves 701 are provided on the outer shaft sleeve 700; the middle part of the lower connecting part 301 has a hollow hole, and the inner wall of the hollow hole is convexly provided with a protrusion 3011, the outer shaft body 500 moves through the hollow hole, and the two protrusions 3011 are respectively and correspondingly embedded in the two grooves 701.
[0043] By arranging the hollow holes, the outer shaft body 500 can pass through the lower connecting portion 301 , and the protrusion 3011 can be movably embedded in the groove 701 , and the protrusion 3011 can move in the groove 701 , thereby realizing the movable connection between the lower blade and the outer shaft body 500 .
[0044] In this embodiment, the outer shaft body 500 is movably sleeved on the outside of the inner shaft body 400, the inner shaft body 400 movably passes through the inside of the outer shaft body 500, and the inner shaft body 400 and the outer shaft body 500 are coaxially arranged. The rotating shaft of the motor can synchronously drive the inner shaft body 400 and the outer shaft body 500 to rotate through the transmission structure, and the rotation direction of the inner shaft body 400 is opposite to the rotation direction of the outer shaft body 500, so that the toy aircraft can fly in the air.
[0045] In this embodiment, the transmission structure includes a driving gear 600 arranged on the rotating shaft, an internal gear 604 connected to the inner shaft body 400, and an external gear 603 connected to the outer shaft body 500. A first transmission gear 601 is meshed between the driving gear 600 and the external gear 603, and a second transmission gear 602 is meshed between the first transmission gear 601 and the internal gear 604.
[0046] The rotating shaft rotates, driving the driving gear 600 to rotate, and then the first transmission gear 601 rotates, driving the outer gear 603 and the second transmission gear 602 to rotate, the outer shaft body 500 rotates, and the second transmission gear 602 drives the inner gear 604 to rotate, and then the inner shaft body 400 rotates. The entire transmission rotation process is carried out synchronously, realizing the synchronous rotation of the inner shaft body 400 and the outer shaft body 500 in different directions.
