Description

模型飞行器技术领域 Model aircraft

本发明涉及一种模型玩具，具体地说，涉及一种模型飞行器，它可以在室内等空间较小的场合飞行，具有结构简单、成本低的优点。背景技术 The present invention relates to a model toy, and more particularly to a model aircraft which can fly in a small space such as a room, and has the advantages of simple structure and low cost. Background technique

飞机模型深受人们的喜爱。飞机模型从复杂的专业级到简单的业余级，品种繁多。对于专业级的产品，因为其成本因素可以较少考虑，故飞行性能较佳。为了保持较好的飞行稳定性，往往需要在模型飞机中安装陀螺仪等稳定系统。但这类稳定系统结构复杂，制作成本高，重量重，体型大，只适合在较高档的产品中应用。此外，安装有陀螺仪的飞机模型因其体积较大，不适合在普通家庭的室内使用。 Aircraft models are loved by people. Aircraft models range from complex professional grades to simple amateur grades. For professional grade products, flight performance is better because its cost factor can be considered less. In order to maintain good flight stability, it is often necessary to install a stable system such as a gyroscope in the model aircraft. However, such stable systems are complicated in structure, high in production cost, heavy in weight, and large in size, and are only suitable for use in higher-end products. In addition, aircraft models equipped with gyroscopes are not suitable for indoor use in ordinary homes due to their large size.

目前市场上也有简易型的模型飞机，这类模型飞机中省缺了陀螺仪，达到了降低成本，减轻重量，缩小体积，但带来了飞行稳定性差和操作性差的缺点。操作者通过遥控器发出指令之后，由于惯性等的作用，模型飞机不能立即作出针对操作者操作的反应。因此，现有产品在成本、重量和性能三方面的兼顾上不尽如人意，尤其缺乏适合普通家庭室内使用的、稳定性好的模型飞机产品。发明内容 There are also simple model aircraft on the market. This type of model aircraft lacks gyroscopes, which reduces costs, reduces weight and reduces volume, but brings the disadvantages of poor flight stability and poor operability. After the operator issues an instruction through the remote controller, the model aircraft cannot immediately respond to the operator's operation due to inertia or the like. Therefore, the existing products are not satisfactory in terms of cost, weight and performance. In particular, there is a lack of stable model aircraft products suitable for indoor use in ordinary homes. Summary of the invention

传统的产品中，在旋翼 40上方还可以通过连杆 60连接一个稳定锤 50，该稳定锤 50在一定程度上起到了稳定飞行器的作用。在本发明的模型飞行器中，该稳定锤并非是必不可少的部件。 In the conventional product, a stabilizer hammer 50 can also be connected via the connecting rod 60 above the rotor 40, which stabilizes the aircraft to a certain extent. In the model aircraft of the present invention, the stabilizing hammer is not an indispensable component.
