Technical Field

[0001] The utility model relates to the technical field of toy airplanes, in particular to a landing gear structure of a toy airplane. Background Art

[0002] Flyable toy airplanes (also commonly referred to as flyable toy airplanes) have been popular with many children and adults for many years. The continuous development of toy airplanes includes the development of small self-powered toys or recreational model airplanes. When landing, toy airplanes need landing gear and taxiing wheels to taxi and slow down, so as to ensure that the toy can land successfully every time, and at the same time, avoid unnecessary damage to the toy airplane. Therefore, the structure of the landing gear needs to have a certain toughness and rigidity to withstand the forces generated during landing.

[0003] In view of the above-mentioned shortcomings of the conventional landing gear structure, the applicant adheres to the spirit of research innovation and excellence, combines production practice, and uses professional and scientific methods to propose a practical solution, and therefore files this application. Utility Model Content

[0004] The utility model aims to provide a toy airplane landing gear structure with reasonable design and simple structure in view of the existing technical status.

[0005] A toy airplane landing gear structure includes: a toy airplane shell, a taxiing wheel, and a connecting plate. The toy airplane shell is divided into a body shell and a wing. A mounting base is provided under the wing. One end of the connecting plate is hinged to the mounting base. A torsion spring is provided inside the connecting plate. The fixing interface of the torsion spring is installed on the mounting base. The taxiing wheel is installed on the pulley interface of the torsion spring. The torsion spring and the connecting plate can not only ensure the toughness of the toy airplane landing gear structure, but also improve the overall aesthetics. The landing gear structure is more durable.

[0006] Specifically, the fixing interface of the connecting plate is a square fixing frame, which is inserted into a slot of the mounting base. A clip is provided at one end of the slot, and one side of the fixing frame is buckled in the clip. The clip can limit one side of the fixing frame.

[0007] Specifically, the pulley interface of the connecting plate extends transversely and is inserted on the sliding wheel. The sliding wheel rotates with the pulley interface as the axis. A layer of rubber tire or resin tire is sleeved on the outside of the sliding wheel. The sliding wheel can rotate smoothly with the axis as the axis.

[0008] Specifically, both ends of one side of the mounting base are provided with double hooks, one end of the connecting plate is provided with a connecting cylinder, the connecting cylinder is inserted into the double hooks, and the connecting plate swings back and forth slightly with the connecting cylinder as the axis.

[0009] Specifically, a buckle is provided on the inner side of the connecting plate, and the connecting arm of the torsion spring is inserted into the buckle. The connecting arm can be preliminarily installed on the connecting plate, and the connecting plate can provide a certain support for the torsion spring.

[0010] Specifically, a raised U-shaped mounting plate is provided on the inner side of the mounting base, the U-shaped mounting plate is installed and fixed under the wing, the slot is arranged on the outer side of the mounting base, and a horizontal bar for clamping the fixing interface of the torsion spring is provided on the mounting base, so as to limit the fixing interface of the torsion spring within a controllable range.

[0011] Specifically, two square holes are provided at the front and rear of the bottom of the slot, leaving a small space, which is not only convenient for the installation of the torsion spring, but also serves as a certain buffer space to reduce the wear of the torsion spring.

[0012] The beneficial effects of the utility model are:

[0013] The toy airplane has landing gear installed under the left and right wings. The landing gear is connected to the sliding wheel through a torsion spring. During the landing of the toy airplane, at the moment the sliding wheel touches the ground, the torsion spring effectively plays a buffering role through its own elasticity compared to the traditional straight rod connection, avoiding direct force on the straight rod, thereby causing damage to parts. The torsion spring is reasonably designed, more practical, and has a longer service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0019] As attached Figures 1 to 3As shown, a toy airplane landing gear structure includes: a toy airplane shell, a taxi wheel, and a connecting plate. The toy airplane shell is divided into a fuselage shell and a wing. A mounting base is provided under the wing. One end of the connecting plate is hinged to the mounting base. A torsion spring is provided inside the connecting plate. The fixing interface of the torsion spring is installed on the mounting base.

The control circuit board drives the front propeller to rotate through the drive motor. The control circuit board controls the swing of the airplane tail through the servo motor. The principle is similar to that of existing toy remote-controlled airplanes and will not be elaborated here.

[0020] When the toy plane is landing and gliding, the moment the taxiing wheel touches the ground, the force after contact with the ground will act on the torsion spring, causing the torsion spring to form a certain elastic deformation and play a certain buffering role. After gliding a certain distance, the external force will be withdrawn and the torsion spring will also recover, thereby increasing the service life of the landing gear structure.

[0021] In the above solution, the fixing interface of the connecting plate is a square fixing frame, which is inserted into the slot of the mounting base, and a clamping strip is provided at one end of the slot, and one side of the fixing frame is buckled into the clamping strip.

A buckle is provided on the inner side of the connecting plate, and the connecting arm of the torsion spring is inserted into the buckle. A raised U-shaped mounting plate is provided on the inner side of the mounting base, and the U-shaped mounting plate is fixed under the wing. The slot is provided on the outer side of the mounting base, and a horizontal bar for clamping the fixing interface of the torsion spring is provided on the mounting base.
