Description

Technical Field

[0001] The utility model belongs to the technical field of flying toys, and in particular relates to a toy aircraft. Background Art

[0002] At this stage, the categories of children's toys are becoming more and more abundant. Various types of aircraft can fly up and down, and move left and right under the control of children. However, today's aircraft are more in the shape of airplanes. To use them for fun, they must be operated in an open space. If the venue is not big enough, on the one hand, it is difficult to make the plane fly, and on the other hand, it is easy to cause a collision and cause damage to the aircraft. Although airplane-like aircraft can be used for children to play, their uncertain flight direction and speed will pose a risk to the personal safety of others to a certain extent.

[0003] Therefore, some people have developed flying vehicles for indoor entertainment. If a person holds up the aircraft with his hands from below, the aircraft can fly upward and continue to soar up and down. However, this type of aircraft also has the risk of uncertain direction and difficulty in control. Although it solves the purpose of indoor entertainment, it still poses a threat to personal safety. Summary of the invention

[0004] In order to solve the above technical problems, the utility model provides a toy aircraft, which can take off by rotating in opposite directions through double-layer rotor blades, thereby achieving the effect of stable vertical flight, and is supplemented by vertical traveling rotor blades for lateral flight movement. The aircraft has a stable flight state and is easy to slot.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A toy aircraft comprises a main body, a driving assembly, a lifting assembly and a connecting rod;

[0007] The driving assembly includes a battery box, a motor seat, a motor group and a gear group, the battery box and the motor seat are both placed in the main body, the motor group is arranged on the motor seat, the gear group is rotatably connected to the motor seat, the battery box is electrically connected to the motor group, the output end of the motor group is meshed with the gear group, the connecting rod extends into the main body and is connected to the motor seat, and the gear group is sleeved on the connecting rod; the motor group includes an outer motor and an inner motor, the gear group includes an outer gear and an inner gear, the outer gear and the inner gear are coaxial and parallel to each other and are sleeved on the connecting rod through a bearing, the output end of the outer motor is meshed with the outer gear, and the output end of the inner motor is meshed with the inner gear.

[0008] The lifting assembly includes a first rotating blade, a first rotating shaft, a first rotating drum, a second rotating blade, a second rotating shaft, a second rotating drum, a balancing shaft, a balancing rod and a stabilizing rod, wherein the first rotating shaft is sleeved on the connecting rod and connected to the gear set, and the first rotating blade is rotatably connected to the outer wall of the first rotating shaft; the first rotating drum is sleeved on the connecting rod and connected to the motor seat through a bearing, the upper end of the first rotating drum is embedded in and fixed in the first rotating shaft, and the lower end of the first rotating drum is embedded in and fixed in the external gear; the second rotating shaft is sleeved on the connecting rod, the second rotating blade is rotatably connected to the outer wall of the second rotating shaft, the second rotating drum is sleeved on the connecting rod and located in the first rotating drum, the second rotating drum is respectively connected to the first rotating shaft and the external gear through bearings, the upper end of the second rotating drum is embedded in and fixed in the second rotating shaft, and the lower end of the second rotating drum is embedded in and fixed in the internal gear; the balancing shaft is detachably connected to the second rotating shaft, the balancing rod is rotatably connected to the outer wall of the balancing shaft, and a counterweight is provided at the end of the balancing rod; the stabilizing rod is respectively connected to the second rotating shaft and the balancing shaft.

[0009] It also includes a traveling component, which includes a fixed seat, a traveling motor and a traveling rotor. The fixed seat is arranged at the top end of the connecting rod, and a transverse air duct is arranged in the fixed seat. The traveling motor is arranged in the fixed seat, and the output end of the traveling motor is connected to the traveling rotor. The traveling motor is electrically connected to the battery box, and the traveling rotor is vertically placed in the transverse air duct.

[0010] In the toy aircraft adopting this structure, the battery box in the main body supplies power to the motor group on the motor seat, and the motor group can be detachably installed on the motor seat. More preferably, the motor seat is provided with a mounting seat for installing the outer motor and the inner motor. The outer motor and the inner motor are both vertically arranged, while the outer gear and the inner gear are placed horizontally and parallel. The inner gear is located below the outer gear and is rotatably connected to the bottom of the motor seat, and the output ends of the outer motor and the inner motor are respectively meshed and connected to the outer gear and the inner gear.

[0011] In order to drive the first rotor blade and the second rotor blade to rotate in different directions respectively during the starting process of the motor group, a connecting column is vertically arranged at the bottom of the motor base and extends vertically upward, the first rotating drum is sleeved on the connecting column and connected to the motor base through a bearing, the upper end of the first rotating drum is embedded in and fixed in the first rotating shaft, and the lower end of the first rotating drum is embedded in and fixed in the external gear, so that during the starting process of the external motor, the external gear meshing with it will be driven to rotate, thereby driving the first rotating shaft to rotate, and rotating the first rotor blade rotatably connected to the outer wall of the first rotating shaft, at least two groups of first rotor blades with the first rotating shaft as the symmetric center rotate under the action of centrifugal force; and the second rotating drum is also sleeved The second rotating drum is located on the connecting column and inside the first rotating drum, and is connected to the first rotating shaft and the outer gear respectively through bearings. The upper end of the second rotating drum is embedded in and fixed in the second rotating shaft, and the lower end of the second rotating drum is embedded in and fixed in the internal gear. Therefore, when the internal motor is started and maintains a rotation direction opposite to that of the external motor, the internal gear meshing with it will be driven to rotate, thereby driving the second rotating shaft to rotate, and rotating the second rotating blades rotatably connected to the outer side wall of the second rotating shaft. At least two groups of second rotating blades with the second rotating shaft as the center of symmetry rotate in opposite directions under the action of centrifugal force, thereby achieving the effect of simultaneous reverse rotation of double-layer rotating blades, offsetting the anti-torsional force brought by each other, and thus achieving smooth up and down flight.

[0012] The lift-off effect brought about by the simple counter-rotating of the double-layer rotor blades is still unstable. The reason is that the downward pressure turbulence of the air under the synchronous rotation causes the aircraft to swing left and right, and the flight state is unstable. Therefore, at least two sets of symmetrical balance rods are installed on the second rotating shaft to synchronously drive the rotation of the balance rod during the rotation of the second rotor blade. The counterweight block at the end of the balance rod can effectively provide stronger centrifugal force, thereby offsetting the left and right swing force caused by the turbulence and ensuring the smooth up and down flight of the aircraft. The setting function of the stabilizing rod is to fix the connection between the second rotating shaft and the balance shaft.

[0013] Due to the lifting effect of the double-layer rotor blades, they move in the up and down directions and cannot achieve horizontal movement without the action of external force. Therefore, a fixed seat is set at the upper end of the connecting rod, and the horizontal air duct in the fixed seat is vertically provided with traveling rotor blades. The traveling rotor blades are driven by a traveling motor. Therefore, when the aircraft is in the air, the traveling rotor blades can be started to assist the aircraft in lateral displacement, thereby achieving flight effects in all directions: up, down, left, right, front and back.

[0014] Furthermore, the main body also includes a first surrounding wall and a second surrounding wall, the first surrounding wall is sleeved on and detachably connected to the first rotating shaft, the second surrounding wall is sleeved on and detachably connected to the second rotating shaft, the first surrounding wall, the second surrounding wall and the main body are coaxial up and down and form a continuous cylindrical shell structure, and the outside of the fixed seat is an upward-folded cone structure.

[0015] Furthermore, it also includes a spray assembly, which includes a water tank and an atomizer. The water tank is placed in the main body and located at the bottom of the main body. A through hole for installing the atomizer is provided on the lower end surface of the water tank, and a plurality of supporting feet distributed in a circle are provided at the bottom of the main body.

[0016] Compared with the prior art, the advantages of the utility model are: by installing an external motor and an internal motor and driving the external gear and the internal gear respectively, the effect of simultaneous opposite rotation of the double-layer rotor blades can be achieved, which can offset the anti-torsional force brought by each other, thereby achieving smooth up and down flight. In order to offset the left and right yaw force brought by turbulence and ensure the smooth up and down flight of the aircraft, a balance bar that rotates synchronously with the second rotor blade is provided, thereby achieving a smoother up and down flight. At the same time, with the assistance of the setting of the moving rotor blade, the aircraft can be displaced laterally, and finally the flight effect in all directions of up, down, left, right, front and back is completed.

The bottom of the main body 1 is provided with a plurality of supporting feet 13 distributed in a circle.

[0039] Description of the working method of this utility model:

[0040] In the toy aircraft adopting this structure, the battery box 21 in the main body 1 supplies power to the motor group 23 on the motor base 22, and the switch provided on the main body 1 is used to open and close the battery box 21. Since this content belongs to the prior art, no excessive elaboration is given here on how to achieve power supply. The motor group 23 can be detachably mounted on the motor base 22. More preferably, the motor base 22 is provided with a mounting base for installing the outer motor 231 and the inner motor 232. The outer motor 231 and the inner motor 232 are both vertically arranged, while the outer gear 241 and the inner gear 242 are placed horizontally and parallel. The inner gear 242 is located below the outer gear 241 and is rotatably connected to the bottom of the motor base 22. The output ends of the outer motor 231 and the inner motor 232 are respectively meshed and connected to the outer gear 241 and the inner gear 242.

[0041] In order to drive the first rotor blade 31 and the second rotor blade 34 to rotate in different directions respectively during the starting process of the motor group 23, a connecting column is vertically arranged at the bottom of the motor base 22 and extends vertically upward. The first rotating drum 33 is sleeved on the connecting column and connected to the motor base 22 through the bearing 7. The upper end of the first rotating drum 33 is embedded in and fixed in the first rotating shaft 32, and the lower end of the first rotating drum 33 is embedded in and fixed in the external gear 241. Therefore, during the starting process of the external motor 231, the external gear 241 meshing therewith will be driven to rotate, thereby driving the first rotating shaft 32 to rotate, and rotating the first rotor blade 31 rotatably connected to the outer wall of the first rotating shaft 32. At least two groups of first rotor blades 31 with the first rotating shaft 32 as the symmetric center rotate under the action of centrifugal force; and the second rotating drum 36 is also sleeved The second rotating drum 36 is arranged on the connecting column and located inside the first rotating drum 33. The second rotating drum 36 is connected to the first rotating shaft 32 and the outer gear 241 respectively through the bearing 7. The upper end of the second rotating drum 36 is embedded in and fixed in the second rotating shaft 35, and the lower end of the second rotating drum 36 is embedded in and fixed in the inner gear 242. Therefore, when the inner motor 232 is started and keeps the rotation direction opposite to that of the outer motor 231, the inner gear 242 meshing therewith will be driven to rotate, thereby driving the second rotating shaft 35 to rotate, and rotating the second rotating blade 34 rotatably connected to the outer wall of the second rotating shaft 35. At least two groups of second rotating blades 34 with the second rotating shaft 35 as the symmetry center rotate in the opposite direction under the action of centrifugal force, so as to achieve the effect of simultaneous reverse rotation of the double-layer rotating blades, offsetting the anti-torsion force brought by each other, thereby achieving smooth up and down flight.

[0042] The lift-off effect brought about by the simple reverse rotation of the double-layer rotor blades is still unstable. The reason is that the downward pressure turbulence of the air under the synchronous rotation causes the aircraft to swing left and right, and the flight state is unstable. Therefore, at least two groups of symmetrical balance rods 38 are installed on the second rotating shaft 35 to synchronously drive the rotation of the balance rod 38 during the rotation of the second rotor blade 34. The counterweight block 381 at the end of the balance rod 38 can effectively provide stronger centrifugal force, thereby offsetting the left and right swing force caused by the turbulence, ensuring the smooth up and down flight of the aircraft. The setting function of the stabilizing rod 39 is to fix the connection between the second rotating shaft 35 and the balance shaft 37.

[0043] Due to the lifting effect of the double-layer rotor blades that move in the up and down directions, horizontal lateral movement cannot be achieved without the action of external force. Therefore, a fixed seat 51 is set at the upper end of the connecting rod 4, and a traveling rotor blade 53 is vertically arranged in the transverse air duct 54 in the fixed seat 51. The traveling rotor blade 53 is driven by a traveling motor 52. Therefore, when the aircraft is in the air, the traveling rotor blade 53 can be started to assist the aircraft in lateral displacement, thereby achieving flight effects in all directions of up, down, left, right, front and back.

[0044] Since the flying effect of the aircraft moving up and down, left and right, forward and backward is similar to that of a starship, a first surrounding wall 11 is set on the first rotating shaft 32, and a second surrounding wall 12 is set on the second rotating shaft 35. The first surrounding wall 11, the second surrounding wall 12 and the main body 1 are coaxial up and down to form a continuous cylindrical shell structure, and the exterior of the fixing seat 51 is an upwardly contracted cone structure. At the same time, a supporting foot 13 is set at the bottom of the main body 1. Therefore, the overall appearance is like a starship launching and hovering in the air, which is more attractive to children to play with it.

[0045] Since the appearance has the effect of a starship, if there is no flame-like spray effect when it is in the air, the toy will appear not real enough. Therefore, a water tank 61 is set at the bottom of the main body 1, and the bottom of the water tank 61 is sprayed through an atomizer 62. If necessary, a light bulb is installed at the bottom of the water tank 61, preferably a red light bulb. When the atomizer 62 and the light bulb are started, the double-layer rotor blades are started at the same time to assist the main body 1 to take off, which can have a simulation effect similar to the launch of a starship, making the toy more interesting. Moreover, after completing the flight, it can land on the spot. After the landing, the first rotor blade 31, the second rotor blade 34 and the balance bar 38 of the aircraft will be folded downward under the action of gravity, and do not occupy space when not started.

[0046] The beneficial effect of the present invention is that by installing the outer motor 231 and the inner motor 232 and driving the outer gear 241 and the inner gear 242 respectively, the double-layer rotor blades can rotate in opposite directions at the same time, which can offset the reverse torsional force brought by each other, thereby achieving smooth up and down flight. In order to offset the left and right yaw force brought by turbulence and ensure the smooth up and down flight of the aircraft, a balance bar 38 that rotates synchronously with the second rotor blade 34 is provided, thereby achieving a more stable up and down flight. At the same time, with the assistance of the setting of the traveling rotor blade 53, the aircraft can be lateral displacement, and finally the flight effect in all directions of up, down, left, right, front and back is completed. At the same time, with the combined effect of the atomizer 62 and the light bulb, a simulation effect similar to the launch of a starship can be achieved, making the toy more interesting.

[0047] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
