[0013] To better control the flight of the toy aircraft, the drive device further includes a signal receiver. The signal receiver is located on the eagle head and is electrically connected to the power unit to control the power unit.

[0014] Compared with the prior art, the beneficial effects embodied by the present utility model are as follows:

[0015] 1. In the present utility model, a chamber is provided in the eagle-shaped housing, and the drive device is arranged in the chamber. By protecting the drive device through the chamber, it can better prevent some drive components such as the power supply and motor on the aircraft from being directly impacted when the aircraft is hit. The drive device is completely wrapped by the eagle-shaped housing, providing a better protection for the drive device and extending the service life of the aircraft. Further, two channels are respectively provided on both sides of the concave chamber, and the channels extend to the eagle wings on both sides. The wires are connected to the power supply in the concave chamber, and the other ends are connected to the motor along the channels to provide power for the propeller blades. By providing channels on the eagle wings, the exposed wires are protected, further extending the service life of the aircraft.

[0016] 2. Since the chamber of the present utility model includes a concave cavity and a cover plate provided on the eagle-shaped housing, and the cover plate is snap-fitted with the concave cavity to form an openable closed chamber. After the power of the driving device on the aircraft is exhausted and components such as the motor and circuit board are damaged, they can be replaced through the openable chamber, further extending the playing time of the aircraft and saving expenses for the players.

[0017] 3. Since there are two through holes respectively provided on the two eagle wings of the present utility model, the propeller group includes propeller blades and a motor, and the motor is drivably connected to the propeller blades.

The setting of the through holes can protect the propeller blades from being directly impacted by foreign objects, reduce the impact force between the propeller group and foreign objects, and extend the service life of the propeller group.

[0018] 4. Since the eagle-shaped housing of the present utility model is made of EPP material, the EPP material has good elasticity, strong resilience, good impact buffering effect, and plays a good role in shock absorption. Moreover, it has good foaming effect. Under the condition of the same volume, its weight is lower. Under the condition of the same weight and the same volume, the EPP material has higher structural strength and can withstand greater pressure and impact force. Therefore, selecting this material to make the eagle-shaped housing can better protect the driving device from damage caused by impact, further enhancing the overall anti-drop strength of the aircraft.

[0019] 5. Since the pulley group of the present utility model includes at least two groups of pulleys, and the two groups of pulleys are respectively located at the front bottom and the rear bottom of the eagle-shaped housing to assist the aircraft in taking off and landing smoothly.

In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features, which are used to distinguish and describe features, without order or importance. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "cooperate", "be connected", "connect", "install" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0031] Such as Figure 1 , Figure 2 , Figure 3As shown in the figure, an aircraft includes an eagle-shaped shell 1 with an internal chamber, a driving device 2, and a pulley block 3. The driving device 2 is arranged inside the chamber. The driving device 2 includes a propeller group 21 and a power unit 22 electrically connected to the propeller group. The propeller group 21 includes at least two propellers, which are respectively arranged on the eagle wings on both sides. Specifically, the chamber includes a concave cavity 12 and a cover plate 11 provided on the eagle-shaped shell 1. The cover plate 11 is snap-connected to the concave cavity 12 to form an openable closed chamber. A snap connector is provided at the inner end of the cover plate 11. A snap groove is provided at one end of the concave cavity 12 corresponding to the snap connector. The snap connector is nested with the snap groove. The snap connector extends outward from the inner side of the cover plate 11 along the edge to the surface of the cover plate 11, forming an opening buckle on the cover plate 11. By upwardly pressing the opening buckle, the cover plate 11 can be opened, thus facilitating the opening and closing of the concave cavity 12. In this embodiment, the snap connector and the snap groove adopt existing technologies, such as existing snap columns and snap grooves, etc., as long as the snap connection between the cover plate and the concave cavity can be realized. Therefore, the structure thereof will not be described in detail here, but it is easily understood by those skilled in the art.

[0032] In this embodiment, as Figure 3 shown, two channels 13 are respectively provided on both sides of the concave cavity 12, and the channels 13 extend to the eagle wings on both sides. Specifically, the power unit 22 includes a power supply 221 and wires. The power supply 221 is connected to the wires, and the wires pass through the channels 13 and are connected to the propellers. The wires on existing aircraft are exposed outside. The exposed wires are extremely likely to be separated from the connection points after the aircraft is hit multiple times, resulting in problems such as electric leakage. Therefore, the wires on toy aircraft also need to be well protected to avoid the detachment of the wires. In addition, it also makes the appearance of the toy aircraft more beautiful and reduces the risk of electric leakage of the wires. Further, two through holes 14 are respectively provided on both sides of the eagle wings. The propeller group 21 includes propeller blades 211 and a motor 212. The motor 212 is drivably connected to the propeller blades 211. The propeller blades 211 rotate in the through holes 14 under the drive of the motor 212. Arranging the propeller blades 211 to rotate in the through holes 14 can protect the propeller blades 211 from being directly hit by the outside and being damaged. On the other hand, it avoids the risk of secondary impact that the toy aircraft directly drops from a high altitude and hits the ground when the propeller blades 211 stop rotating after being hit during the flight of the toy aircraft.

[0033] In this embodiment, the eagle-shaped housing 1 is made of EPP material. EPP is a polypropylene plastic foaming material, which is an excellent high-crystalline polymer / gas composite material. In addition, the polypropylene plastic foaming material has a light specific gravity, good elasticity, earthquake resistance and compression resistance, a high deformation recovery rate, good absorption performance, oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, non-water absorption, insulation, heat resistance (-40~130°C), and is non-toxic and odorless. The utility model utilizes the good performance of the polypropylene plastic foaming material. The toy aircraft prepared with this material is suitable for children to play with, and its overall weight is lighter than that of other types of materials. Using the same type of power supply 221 and motor, the flight time and speed of the toy aircraft of the utility model are faster and more durable. In addition, the overall anti-drop strength of the toy aircraft of the utility model is stronger, and it can better protect the driving device 2 in the chamber in the face of multiple impacts.

[0034] Further, as Figure 2 shown, the pulley group 3 includes at least two sets of pulleys. The two sets of pulleys are respectively located at the front bottom and the rear bottom of the eagle-shaped housing 1 to assist the aircraft in taking off and landing smoothly. Specifically, the pulley group 3 includes a first pulley 31 and a second pulley 32. The first pulley 31 is located at the front end of the eagle-shaped housing 1, and the second pulley 32 is located at the rear end of the eagle-shaped housing 1. Specifically, the second pulley 32 is located at the tail wing part of the eagle-shaped housing 1. The diameter and size of the first pulley 31 are larger than those of the second pulley 32. That is to say, compared with the second pulley 32, the second pulley 32 has a simpler structure, smaller size and mass. When landing normally, the first pulley 31 and the second pulley 32 touch the ground at the same time. Therefore, when the toy aircraft slides on the ground after landing, the toy aircraft has a large angle of attack with the ground, and a large resistance can be used to decelerate, so as to reduce the landing time and the sliding distance.

[0035] In this embodiment, as Figure 3 shown, there are two grooves 15 on both sides of the eagle wings. There is a fixing seat 2121 on the motor 212. The fixing seat 2121 wraps around the periphery of the motor 212. The motor 212 is fixedly connected to the groove 15 through the fixing seat 2121. The fixing seat 2121 forms a protective housing for the motor 212 to prevent the motor 212 from being directly impacted and reduce the damage to the motor 212 during the impact of the toy aircraft.

[0036] In this embodiment, as Figure 4 shown, the driving device 2 further includes a signal receiver 4. The signal receiver 4 is located on the eagle head and is electrically connected to the power unit 22 to control the power unit 22, so as to better control the flight of the toy aircraft.

[0037] In the description of this specification, the descriptions referring to terms such as "embodiment", "example", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.

[0038] In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
