Description

Technical Field

[0001] The utility model relates to the technical field of aircraft models, in particular to a deformable aircraft model. Background Art

[0002] A model aircraft, or aviation model, is a model built to resemble an aircraft's shape and designed to fly under specific conditions. Wings of different shapes and sizes create varying amounts of air resistance. Narrower, thinner wings can reduce air resistance, thereby increasing the aircraft's flight speed. Conversely, wider, thicker wings may provide greater lift but increase air resistance, resulting in a relatively lower speed.

[0003] Some wing designs have a larger wingspan or special wing shape, which can increase the stability of the model aircraft. However, the wings on the current model aircraft are mostly designed as one piece with the fuselage, and cannot be replaced with wings of different shapes according to actual needs. There are certain limitations. Therefore, it is necessary to design a deformable aircraft model to solve the above problems. Utility Model Content

[0029] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The utility model provides a deformable aircraft model, comprising:

[0030] The aircraft model fuselage 1 is provided with a replacement and deformation mechanism. It should be noted that wings 4 of different shapes can be selected as needed, and then the wings 4 can be replaced to obtain different flight performances, so that the entire aircraft model can be deformed;

[0031] The replacement deformation mechanism includes an assembly block 3, a wing 4, a slider 5, a piston plate 7, a positioning block 9, an elastic sealing airbag 1 13 and an elastic sealing airbag 2 14;

[0032] The assembling block 3 is clamped together with the aircraft model fuselage 1, the wing 4 is fixedly connected to the assembling block 3, the top of the slider 5 is fixedly connected to the piston plate 7, the side of the slider 5 is fixedly connected to the positioning block 9, the positioning block 9 is clamped together with the assembling block 3, and the elastic sealing airbag 1 13 and the elastic sealing airbag 2 14 are both embedded in the aircraft model fuselage 1. It should be noted that the elastic sealing airbag 1 13 and the elastic sealing airbag 2 14 are fixedly connected to the inside of the aircraft model fuselage 1;

[0033] A piston cavity 8 is provided on the aircraft model body 1 , an air flow channel 15 is provided between the elastic sealing airbag 1 13 and the elastic sealing airbag 2 14 , and an air flow channel 2 16 is provided between the air flow channel 15 and the piston cavity 8 .

[0034] Through the above-mentioned replacement and deformation mechanism, when it is necessary to replace the wings of different shapes, first release the limit on the support frame 6, then pull the support frame 6 downward, then take out the wing 4, and replace it with a wing 4 of a different shape; push the support frame 6 upward, so that the positioning block 9 can be stuck in the positioning groove, and the assembly block 3 is limited. During this process, the piston plate 7 moves upward, so that air can be blown into the flow channel 2 16 and the flow channel 1 15, and then the elastic sealing airbag 1 13 and the elastic sealing airbag 2 14 can be expanded. The elastic sealing airbag 1 13 can well seal the gap between the assembly block 3 and the assembly groove 2, and the elastic sealing airbag 2 14 can well seal the gap between the slider 5 and the model aircraft fuselage 1, so that the sealing after installation can be guaranteed, and finally the limit locking can be performed by fixing the screw 12.

[0035] Specifically, the replacement deformation mechanism also includes a support frame 6 and a fixing screw 12. The support frame 6 is fixedly connected to the slider 5. The support frame 6 is fixedly installed on the model aircraft fuselage 1 through the fixing screw 12. It should be noted that this makes it convenient to fix the support frame 6 on the model aircraft fuselage 1.

[0036] Specifically, the elastic sealing airbag 1 13 is in sealing contact with the assembly block 3, and the elastic sealing airbag 2 14 is in sealing contact with the slider 5. Both the elastic sealing airbag 1 13 and the elastic sealing airbag 2 14 are provided with inflation and deflation air pipes, which are fixedly installed in the air flow channel 1 15. It should be noted that the elastic sealing airbag 1 13 can well seal the gap between the assembly block 3 and the assembly groove 2, and the elastic sealing airbag 2 14 can well seal the gap between the slider 5 and the model aircraft fuselage 1, thereby ensuring the sealing after installation.

[0037] Specifically, assembly grooves 2 are provided on both sides of the model aircraft fuselage 1, and the assembly blocks 3 are clamped in the assembly grooves 2. A movable groove 11 is provided on the inner wall at the bottom of the assembly groove 2, and the positioning block 9 is slidably installed in the movable groove 11. It should be noted that this facilitates the vertical movement of the positioning block 9.

[0038] Specifically, the piston plate 7 is slidably installed in the piston cavity 8, and the side surface of the wing 4 is in contact with the fuselage 1 of the model aircraft. It should be noted that the position of the wing 4 is limited.

[0039] Working principle:

[0040] S1: When it is necessary to replace a wing of a different shape, first release the limit on the support frame 6, then pull the support frame 6 downward, so that the slider 5 drives the piston plate 7 and the positioning block 9 to move, so that the positioning block 9 moves out of the positioning groove. When the piston plate 7 moves downward, it can extract the air in the flow channel 2 16 and the flow channel 1 15, so that the elastic sealing airbag 1 13 and the elastic sealing airbag 2 14 can be contracted. Then, the wing 4 is taken out and replaced with a wing 4 of a different shape.

[0041] S2: Insert the assembling blocks 3 on the wings 4 of different shapes into the assembling slots 2, and push the support frame 6 upwards to make the positioning blocks 9 fit into the positioning slots, thus limiting the position of the assembling blocks 3;

[0042] S3: During this process, the piston plate 7 moves upward, so that air can be blown into the flow channel 2 16 and the flow channel 1 15, thereby causing the elastic sealing airbag 1 13 and the elastic sealing airbag 2 14 to expand. The elastic sealing airbag 1 13 can well seal the gap between the assembly block 3 and the assembly groove 2, and the elastic sealing airbag 2 14 can well seal the gap between the slider 5 and the model aircraft fuselage 1, so as to ensure the sealing after installation. Finally, the fixed screw 12 can be used for limit locking, which is convenient to replace.

This article uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention.
