Description

飞行器玩具 技术领域
本申请涉及一种玩具， 尤其涉及一种大体积的飞行器玩具。
背景技术
近年来， 飞行器玩具越来越多新造型层出不穷， 从飞机到飞碟， 甚至各种鸟类、 昆虫， 各类繁多， 常见的飞行器玩具包括机体和遥控器， 其中， 机体包括螺旋桨单元、 机身和脚 架， 螺旋桨单元为单桨式或双桨式， 单桨式是设在机身上部的一组螺旋桨， 双桨式是设在 机身上部的两组螺旋桨， 用于实现飞行器的升空， 螺旋桨由单马达驱动； 机身包括头盖、 与头盖相边的机身主体和尾体， 尾体固定连接于机身主体的后部， 尾体上安装尾翼， 辅助 飞行器在飞行过程中的平衡控制， 以实现飞行器的平衡和辅助转向， 部分飞行器也可由上 部的螺旋桨或转向装置实现转向功能， 再由尾翼辅助平衡控制， 但此类结构适应于飞行器 体积较小的情形， 由于大体积的飞行器阻力较大， 此种设计使飞行升力效能差， 稳定性也 较差； 且单个马达因控制状态转换时的频繁转向操作造成机械摩擦增加和电能损耗， 使能 耗增大， 造成电池寿命短， 对¾机要求高， 成本大， 易发热， 易产生故障， 减少电池电机 使用次数、 寿命。 且单个马达因控制状态转换时的频繁转向操作， 造成飞行器的控制操作 过程不平缓， 飞行器飞行不够稳定且遥控操作不流畅； 且单个马达不能实现机身的左、 右 转动或静止不动的操控。 而且类似大体积的圆柱体， 如各种瓶状或其他饮料罐等形状， 这 类的飞行器是没有， 如此更具观赏性， 而且能充当商业推销工具的飞行器是没有的。
申请内容
本申请的目的在于克服以上不足，提供一种螺旋桨分放设置在壳体上下部的构造奇特 的螺旋桨系统； 且因由两个独立传动系统带动而造成飞行物转向可控或静止更具观赏性的 飞行器； 和壳体突破现在机型的大体积的圆柱形或其他形状造形独特的飞行器玩具。
为了解决上述技术问题，进行本申请改进。本申请提供一种飞行器玩具，包括螺旋桨、 机身和起落架， 所述螺旋桨包括第一螺旋桨和第二螺旋桨， 所述第一螺旋桨安装在机身的 顶部， 所述第二螺旋桨安装在机身和下方起落架之间； 所述的第一螺旋桨和第二螺旋桨并 不限定说上部只有一组叶片， 它们可以包括二个或三个上下放置的叶片或共同放置在同一 平面的几个叶片， 本申请的意义在于机身的上下分别设有螺旋桨。
所述两个螺旋桨， 它们的转动轴在同一竖直线上。 它们的转动轴为上下分离式结构在
I 同一竖直线上。 带动转动轴的传动装置各自独立， 安装方向相反。 包括两个马达， 所述第 一螺旋桨由其中的第一个马达驱动， 第二螺旋桨由第二个马达驱动， 旋转方向相反。 但所 述传动装置并不局限于二个马达，可由单马达或多马达驱动。可由单马达带动第二螺旋桨， 第二螺旋桨为动力桨， 带动飞行器上升， 第一螺旋桨在气流的作用下做相反方向的被动旋 转。 或者是由单马达同时带动第一、 第二螺旋桨， 第一螺旋桨与第二螺旋桨做相反方向的 旋转。
所述机身为圆柱体、 瓶形、 立方形、 棱形、 规则形体或不规则体。
所述第一螺旋桨包括连接块、 叶片和平衡杆， 所述连接块、 叶片和平衡枰采用铰链连 接； 所述第二螺旋桨包括连接块和叶片， 叶片安装在连接块的末端。
所述平衡杆包括平衡主杆和平衡锤， 平衡棰设置在平衡主杆的末端。
所述平衡杆与第一螺旋桨的连接块采用铰链连接。
所述第一螺旋桨是一字形单片或十字形叶片， 第二螺旋桨是一字形单片或十字形叶 片。
通过大胆改变飞行器结构， 此结构前所未有： 在飞行器上方、 下方各安装螺旋桨， 通 过试验， 发现此设计使飞行器更具稳定性， 飞行效能、 可操控性较为理想， 尤其对于机体 体积较大， 空气阻力因而更大的机型， 上、 下螺旋桨设计， 使受阻体积减小一半， 提高升 力， 此类结构对大面积飞行器更适应。
经过反复试验， 发现用共轴双层螺旋桨， 由于机体体积大， 受阻阻力大， 提升力差， 且存在一定磨擦力， 效能较差， 稳定性受影响， 为此将螺旋桨结构选进行改造， 改为轴心 同一直线， 但实体从中间断开的两个独立转动轴， 不用共轴装置， 解决以上阻力大、 效能 差、 不稳定问题。
相对于现有技术， 本申请飞行器玩具的优点如下，
1、 采用上、 下螺旋桨设计， 使受阻面积减小了一半， 有效地提高了飞行器的提升 力， 且飞行较稳定；
2、 两根同中心线的传动轴，减少了马达因转向时在共轴上产生的摩擦力和能量损 耗， 并使操控稳定性得到有效提高。
3、 采用易拉罐、 瓶状等各种形状机身， 突破以往飞行器的表现方式， 这种造型是 不具有机尾的全新造型， 适用领域更加广泛， 并使飞行器造型美观、 多样化， 机身更具观赏性。
4、 螺旋桨各连接部件多为铰接， 即螺旋桨为活动型螺旋桨， 撞击中不易变形， 有 效避免伤害到操控者， 大大提高玩耍时的安全性。
5、 用双马达各控制上下螺旋桨， 避免了单个马达控制时机体跟着旋转增加摩擦 力， 能耗大。 而且可对飞行器实现彻底操控， 可向左旋转， 也可向右旋转， 也 可静止不动， 且控制更流畅、 利落。
这样， 飞行器在空中造型多样化， 能适应各种商业用途、 如广告等， 实现产品功能多 样化， 为此领域开拓新的表现方式及应用渠道， 对大体积物体飞行器是一巨大突破， 是一 种结构型式应用领域的新创造。例如，壳体可设计为类似可口可乐、百事可乐或其他罐体， 做为宣传和礼品都是很独特的设计和造型。

第二螺旋桨 320为一字形单片， 包括连接块 321和叶片 323， 连接块 321是具有对称 结构且带中心孔的板件， 连接块 321的中部为方形， 连接块 321沿中部方形块的两对边分 别向外延伸出一凸臂 3211， 两凸臂 3211分别与第二螺旋桨 320的两叶片 323铰接， 连接 块 321上设有固定座 3213，连接块 321通过固定座 3213与传动轴 520固定连接；叶片 323 的数量为两片， 叶片 319的前沿稍为向上而后沿向下。 由于采用上、 下螺旋桨设计， 第二 螺旋桨 320几乎无受阻面， 使两螺旋桨的受阻面积减小了一半， 有效地提高了飞行器玩具 的提升力； 且采用带平衡杆 311的第一螺旋桨 310与第二螺旋桨 320配合动作， 使飞行器 的稳定性得到有效提高， 飞行更稳定； 另由于两螺旋桨各结构件之间的连接多为铰接， 即 螺旋桨为活动型螺旋桨， 不仅在撞击中不易变形， 还能有效避免伤害到操控者， 大大提高 玩耍时的安全性； 且由于螺旋桨采用铰接， 使螺旋桨的叶片可折叠， 大大缩小了整机的体 积， 从而减小了产品包装箱的体积， 大大方便了运输及携带的便利性， 还节省运输成本。 此种结构在大型飞行器上效果更好。
如图 2所示， 机身壁是中空的易拉罐形即圆柱形， 包括上盖 501、 下盖 502、 前壁 504 和后壁 505，上盖 501上设有中心孔 5011，下盖 502上设有中心孔 5021、信息接收孔 5023 和端口安装孔 5025， 前壁 504和后壁 505上分别设有卡梢和卡口， 以便于装配定位， 前壁 504和后壁 505扣合后， 上端盖上上盖 501， 下端扣上下盖 502， 在各连接缝处用透明胶进 行固紧。 如机身还可设计为瓶形、 立方形、 棱形、 规则形体或不规则体， 这种机身主要是 针对现有形状中没有机尾的造形。 上下两个螺旋桨系统本身就具有对称平衡性， 因而更适 用于这种造型， 当然也适用于现有的飞机机型。
传动系统 53包括传动轴 520、 传动齿轮 530、 动力源 540和机架 550， 其中， 传动轴 520包括第一传动轴 521和第二传动轴 522， 其中第一传动轴 521和第二传动轴 522为同 中心线的两根轴， 第一传动轴 521为阶梯轴结构， 其上端与第一螺旋桨 310连接， 第一传 动轴 521下端与机架 550固定连接， 第二传动轴 522的上端与机架 550固定连接， 第二传 动轴 522的下端与第二螺旋桨 320和轴端座 5223连接； 传动齿轮 530包括第一传动齿轮 531和第二传动齿轮 532，第一传动齿轮 531的轮辐上均匀分布有小孔， 第二传动齿轮 532 的轮辐上均匀分布有小孔， 轮辐上开小孔是为减轻齿轮的重量； 动力源 540包括第一马达 541和第二马达 542， 第一马达 541的动力输出轴上固定安装一马达轴齿轮 5411， 第二马 达 542的动力输出轴上固定安装一马达轴齿轮 5421 ;机架 550包括上机架臂 551和下机架 臂 552， 上机架臂 551在中心位置的上部设有一轴套 5511， 第一传动轴 521的下端穿过轴 套 551 1 后与第一传动齿轮 531 固定连接， 下机架臂 552 在中心位置的下部设有一轴套 5521 , 第二传动轴 522的上端穿过轴套 5521后与第二传动齿轮 532固定连接， 使第一传 动齿轮 531和第二传动齿轮 532定位于上机架臂 551和下机架臂 552之间， 上机架臂 的周边上设有通孔 5513， 下机架臂 552的周边上设有垂直向上延伸的螺孔座 5521， 上机 架臂 551与下机架臂 552通过通孔 5513与螺孔座 5521进行螺栓固定连接， 下机架臂 552 的一端设有两个定位孔 5523， 两定位孔 5523沿下机架臂 552的径向对称分布在下机架臂 552的旋转切线上，第一马达 541和第二马达 542固定安装于两定位孔 5523中， 第一马达 541的马达轴齿轮 541 1与第一传动齿轮 531啮合， 第二马达 542的马达轴齿轮 5421与第 一传动齿轮 532啮合。 由于采用两根同中心线的传动轴， 避免了单个马达因控制状态转换 时的频繁转向操作造成机械摩擦增加和电能损耗； 减少了辅助转向的尾翼结构， 使机身结 构更简单； 由于采用双轴独立传动控制， 使双螺旋桨的相互配合更灵活、 稳定， 大大降低 使用者的操作难度， 且控制更流畅、 利落。
控制器 57安装在下盖 502上， 电源 59定位在机身 50内适当的位置， 电源 59连接控 制器 57， 为控制器 57提供电能， 控制器 57通过下盖 502上的信息接收孔 5023接收来处 遥控器的控制信号后， 分别控制第一马达 541和第二马达 542动作， 经第一马达 541的马 达轴齿轮 541 1与第一传动齿轮 531的啮合转动，将动力传递至第一传动轴 521， 由第一传 动轴 521带动第一螺旋桨 310转动， 或由第二马达 542的马达轴齿轮 5421与第二传动齿 轮 532的啮合转动，将动力传递至第二传动轴 522，由第二传动轴 522带动第二螺旋桨 320 转动， 实现双螺旋桨的独立控制， 并通过控制提供给两螺旋桨的电流， 实现对两螺旋桨转 速的控制。
如图 2所示， 起落架 70安装在机身 50下部， 位于第二螺旋桨 320和第二传动轴 522 的轴端座 5223之间，起落架 70为三角支架，起落架 70上设有加强筋 703和支架轴套 705， 加强筋 703为环形， 分为三段弧， 分别连接于各支架之间， 支架轴套 705设置于起落架 70 的三角支架 701的上部中心， 第二传动轴 522与支架轴套 705间隙配合安装。
当飞行器需左转向时， 由控制器 57控制第一螺旋桨 310产生的作用力大于第二螺旋 桨 320 的作用力， 则飞行器实现左转向操作。 同理， 当飞行器需右转向时， 由控制器 57 控制第一螺旋桨 310产生的作用力小于第二螺旋桨 320的作用力， 则飞行器实现右转向操 作。
当第二螺旋桨 320旋转产生的反向作用力与第一螺旋桨 310产生的作用力相互抵消 时， 飞行器的机身 50实现静止不动。
悬空是上下螺旋桨产生的升力获得一个等量稳定值时可出现悬空， 与操控者操控技术 有关。
