Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 illustrates a toy aircraft 10 that is capable of following a predetermined trajectory in some preferred embodiments of the present invention. The toy aircraft 10 comprises a frame assembly 1, a driving assembly 2 and an air moment adjusting assembly 3; the frame assembly 1 plays a role in supporting and mounting the rest assemblies, the driving assembly 2 is used for providing acting force for driving the frame assembly 1 to move or cruise along a preset track, and the air moment adjusting assembly 3 is used for adjusting the magnitude of air moment applied to the tail part of the frame assembly 1 during cruising.

As shown in fig. 1 to 4, the driving assembly 2 includes a driving member 21 disposed on the frame assembly 1 and a blade 22 connected to the driving member 21; the air moment adjusting assembly 3 comprises a tail wing 31 rotatably arranged on the rack assembly 1 and a fixing structure 32 arranged on the rack assembly 1;

wherein the end 312 of the rear wing 31 is adapted to swing upward or downward when the rear wing 31 rotates, so that the end 312 of the rear wing 31 is inclined obliquely backward and upward and fixed by the fixing structure 32, or the end 312 of the rear wing 31 is kept horizontal with the front end 311 and fixed by the fixing structure 32.

It will be appreciated that the drive 21 may be an electric motor for providing torque to the blades 22. The blades 22 are used to propel the air through a qualitative flow when turning, enabling the airframe assembly 1 to move or sail directionally. The tail 31 is located at the rear end of the rack assembly 1, which is the end of the rack assembly 1 corresponding to the head end. The fixing structure 32 is used to fix the end of the rear wing 31 when the rear wing 31 is rotated to a desired position.

It will also be understood that the front end 311 of the tail 31 refers to the end facing the head of the airframe assembly 1 and the distal end 312 of the tail 31 refers to the end opposite the head of the airframe assembly 1.

Under the condition that the flight space is enough and the aircraft can cruise at a higher speed, the buoyancy acting on the rack assembly 1 is increased due to the higher flight speed, and the head and the tail of the rack assembly 1 can be supported to keep balance; and when the flight space is limited, when the flying speed is on the low side, the upper buoyancy acting on the rack assembly 1 can be reduced due to the reduction of the flying speed, the head weight of the rack assembly 1 is difficult to support, and after the tail end 312 of the tail fin 31 swings upwards and is fixed through the fixing structure 32, the size of the air moment received by the tail fin 31 is increased, and because the air moment is positioned at the tail part of the rack assembly 1 and points downwards, the tail part of the rack assembly 1 has the trend of pressing downwards, and then the head part and the tail part of the rack assembly 1 can be kept balanced in the same way, and the phenomenon that the head is planted when the low-speed cruising is avoided.

It should be noted that the width of the tail fin 31 gradually increases from the front end 311 to the rear end 312, and therefore, in the case that the tail fin 31 is inclined and the aircraft flies forward, the windward area of the rear end of the tail fin 31 is larger than the windward area of the front end of the tail fin 31, which means that the air moment acting on the rear end 312 is larger than the air moment acting on the front end 311, so that the air moment generated by the contact between the tail fin 31 and the airflow is larger closer to the rear end of the rack assembly 1, which is more helpful for the aircraft to keep the balance between the head and the tail at a low speed, which is helpful for the accelerated climbing of the aircraft, and also avoids the head falling caused by the small floating force of the rack assembly 1.

As shown in fig. 2 and 4, the fixing structure 32 may include a plurality of fastening teeth 321 disposed on the frame assembly 1, and the plurality of fastening teeth 321 are used to abut against the end 312 of the tail 31 to complete the fixing.

It can be understood that the fastening teeth 321 are provided to prevent the end 312 of the rear wing 31 from swinging, and especially prevent the rear wing 31 from being returned to a position where the moment of air is small due to the action of the moment of air during high-speed cruising.

As shown in fig. 2, the rack assembly 1 may be provided with a spacing groove 111 in some embodiments, and a small diameter end 1111 with a smaller groove width and a wide diameter end 1112 with a larger groove width are provided in the spacing groove 111; the tail fin 31 is inserted into the clearance groove 111, the front end 311 of the tail fin 31 is rotatably provided at the small-diameter end 1111, and the tip end 312 of the tail fin 31 slidably abuts against the large-diameter end 1112.

As can be appreciated, the avoiding groove 111 is used for accommodating and limiting the tail 31; the small diameter end 1111 is an end close to the head of the rack assembly 1 in the avoidance slot 111, the wide diameter end 1112 is an end opposite to the small diameter end in the avoidance slot 111, the distance between the wide diameter end 1112 and the small diameter end 1111 corresponds to the distance between the front end 311 and the tail end 312 of the tail 31, and the tail 31 can be limited to a certain extent after penetrating through the avoidance slot 111.

It will be appreciated that the width of the small-diameter end 1111 corresponds to the thickness of the tail 31, and contributes to further securely holding the head 321 of the tail 31. The width of the wide end 1112 corresponds to the swing range of the tail end 312 of the tail 31, i.e. the wide end 1112 is used for providing the tail end 312 with a swing space up and down.

As shown in fig. 2, in some embodiments of toy vehicle 10, front end 311 of tail 31 defines a fastening groove 3111, fastening groove 3111 crosses the groove wall of clearance groove 111, the bottom of fastening groove 3111 abuts the groove wall of clearance groove 111, and the groove walls of fastening groove 3111 abut frame assembly 1 from opposite sides.

It can be understood that the front end 311 of the tail 31 is prevented from falling out of the clearance groove 111 when the tail end 312 of the tail 31 swings up and down, and the tail 31 is prevented from swinging and falling out during cruising.
