[0033] 为了使本发明所要解决的技术问题、 技术方案及有益效果更加清楚明白, 以下 结合附图及实施例, 对本发明进行进一步详细说明。 应当理解, 此处所描述的 具体实施例仅仅用以解释本发明, 并不用于限定本发明。
[0034] 实施例一:
[0035] 如图 1及图 2所示, 本发明的实施例一提供了一种抬升结构 10, 其包括抬升主 体 1, 抬升主体 1上设置有用于安装吹风与吸风装置的安装位 11以及风道 12。
[0036] 风道 12的顶壁 121a为曲面, 抬升主体 1的顶面 13为曲面。 风道 12具有与外界连 通的进风口 122以及出风口 123, 出风口 123与安装位 11连通, 顶壁 121a对应于进 风口 122以及出风口 123的位置分别与抬升主体 1的顶面 13相接, 并且相接处均为 一段曲面, 从而分别形成弓 I导气流进入风道的第一弓 I导结构以及弓 I导气流吹向 抬升主体顶面的第二引导结构。
[0037] 本实施例中, 安装位 11为一安装槽, 安装槽的槽口位于抬升主体 1的顶面上, 当然, 本发明并不限制安装位 11的具体位置, 只要是位于抬升主体 1的顶面上或 者风道 12内即可。
[0038] 于本实施例中, 抬升主体 1内设置一个风道 12以及一个安装位 11。 所述风道 12 位于安装位 11下方位置, 其出风口 123与安装位 11底部连通。 进风口 122为所述 抬升主体 1底部周缘上的环形幵口。
[0039] 风道 12的顶壁 121a为中部凸起的曲面, 抬升主体 1的顶面 13也为中部凸起的曲 面。 于所述抬升主体 1的纵向截面上, 所述风道 12顶壁 121a与所述抬升主体 1的顶 面 13构成一个或两个封闭的曲线, 优选地, 该曲线为一个倾斜于水平面的椭圆 ; 当然, 该曲线还可以是其他的形状。
[0040] 为了增加抬升主体 1底面 14与大气的接触面积, 使抬升结构得到更大的抬升能 力。 抬升主体 1的底面 14具有曲面, 该曲面可以是弧形曲面、 波浪状曲面等所有 比平面具有更大面积的形状。 优选地, 本实施例的抬升主体 1底部具有凹槽 15, 槽内空间呈圆锥形。 风道 12的底壁对应于进风口 122的位置向上翘起, 从而可避 免外界的气流进入风道, 影响气流循环。
[0041] 抬升主体 1具有用于容纳物品和 /或生物的空间, 从而使得抬升主体可作为一个 运输的载体。
[0042] 风道 12内或者抬升主体 1的顶面 13上设置有用于引流或阻挡气流的机构。 本实 施例的安装位 11位于风道 12中间的正上方位置, 以安装位 11为中心, 该风道 12 形成左、 右两侧, 抬升主体 1的顶面 13也形成左、 右两侧。 如果想抬升结构在水 平方向上运动, 可以在安装位 11内的左、 右两侧分别设置一个用于吹风与吸风 的装置。 其中, 一个装置的出风口朝向风道 12左侧, 另一装置的出风口朝向风 道 12的右侧, 并且, 左侧以及右侧的风道 12内或者抬升主体 1顶面 13上的左侧以 及右侧上均设置有用于引流或阻挡气流的机构。 当启动左侧的机构后, 左侧风 道 12内的气流量减少, 气流的速率减少, 此吋左侧装置喷出的气流的冲量要比 右侧装置喷出的气流的冲量小, 此吋, 抬升结构即往右侧运动。 反之, 如果想 抬升结构在水平方向上往左运动, 启动右侧的机构即可。 当然, 如果只想抬升 结构于竖直方向上抬升, 只需安装一个吸风与吹风装置即可。
[0043] 请一同参见图 3, 本实施例的抬升结构通过可吹风与吸风的装置 2从风道 12中吸 入气流, 并吹向抬升主体 1顶面 13。 顶面 13上的气流速度增加, 气压下降, 而抬 升结构下方的气压不变, 因此, 抬升结构被抬升。 并且, 由于康达效应, 从装 置喷出的气流会贴着抬升主体 1的顶面 13与风道 12出风口 123相接处的曲面流入 抬升主体 1的顶面 13, 接着又在康达效应的影响下, 贴着抬升主体 1的顶面 13与 风道 12进风口 122相接处的曲面进入风道 12, 继续参加气流循环, 所以, 气流能 在抬升主体 1的顶面 13与风道 12内不断循环, 气流的动能可以被重复利用, 提高 了能源的重复使用率; 有利于节省能源, 使飞行器在无补给的情况下, 可远距 离飞行。
[0044] 请参见图 4, 本实施例还提供了一种飞行单元 100, 包括上述抬升结构 10、 用于 吹风与吸风的第一装置 21以及用于吹风与吸风的第二装置 22。 所述第一装置 21 以及第二装置 22均安装于安装位 11内, 并且, 第一装置 21的进风口朝向风道左 侧, 其出风口朝向抬升主体 1顶面 13左侧; 第二装置 22的进风口朝向风道 12右侧 , 其出风口朝向抬升主体 1顶面 13右侧。 在实际应用中, 上述的第一装置 21或第 二装置 22可采用单个或多个风机, 也可采用单个或多个风机结合风道的结构形 式。 其中, 本实施例中第一装置 21或第二装置 22的类型及其进风、 出风的形式 不进行限制, 例如, 可以是螺旋进风 /出风的形式, 也可以直线进风 /出风的形式 [0045] 当第一装置 21以及第二装置 22喷出的气流的冲量相同吋, 两者产生的冲力相互 抵消, 抬升结构 10在水平方向上无运动, 而抬升主体 1顶面 13上的气流速度增加 , 气压下降, 抬升结构 10下方的气压不变, 因此, 抬升结构 10被抬升。 当飞行 单元 100需要在水平方向移动吋, 可通过用于引流或阻挡风流的机构来控制风道 左侧或右侧内的气体速度或流量来实现。 当然, 如果只想飞行单元 100于竖直方 向上抬升, 只需安装一个吸风与吹风装置即可。
[0046] 请参见图 5, 本实施例还提供了一种飞行器 300, 包括飞行主体 200以及上述的 飞行单元 100。 所述飞行主体 200为自身可运动的物体、 自身不能运动的物体、 自身可飞行的物体或者自身不可飞行的物体。
[0047] 综上所述, 本实施例通过于飞行单元 100或飞行器 300上安装上述的抬升结构 10
, 使飞行单元 100或飞行器 300的能量得到了重复利用, 使其可在无补给的情况 下, 实现远距离飞行。
[0048] 实施例二:
[0049] 请参见图 6及图 7, 为本发明的实施例二, 提供了一种抬升结构, 除以下的内容 夕卜, 本实施例的其他内容均与实施例一相同。
[0050] 于抬升主体 1的纵向截面上, 风道 12顶壁 121a与抬升主体 1的顶面 13构成一个封 闭的曲线。 优选地, 该曲线为一个水平放置的椭圆。
[0051] 安装位 11设置于抬升主体 1的顶面 13上, 抬升主体 1的顶面 13为安装位 11的槽底
, 为了避免外界的气流进入风道, 影响气流循环, 安装位 11的两侧设置有挡风 壁 111。
[0052] 实施例三:
[0053] 请参见图 8, 本实施例提供了一种抬升结构, 除以下的内容外, 本实施例的其 他内容均与实施例一相同。

[0055] 抬升主体 1底面 14为波浪状曲面, 从而可增加底面 14与大气的接触面积, 使抬 升结构得到更大的抬升能力。
[0056] 实施例四: [0057] 请参见图 9, 本实施例提供了一种抬升结构, 除以下的内容外, 本实施例的其 他内容均与实施例一相同。

[0061] 风道的顶壁为中部凸起的曲面, 抬升主体的顶面为中部凹陷的曲面。 由于顶面 轮廓的特性, 气流无需借助康达效应也能贴着顶面流动, 然后通过第一引导结 构进入风道。 气流在风道内沿着风道流动, 流动至出风口位置吋, 在第二引导 结构的引导下, 继续吹向抬升主体的顶面, 进而, 气流可以在抬升主体顶面上 以及风道内不断地循环流动。
[0062] 进风口为抬升主体顶面上的局部幵口, 具体地, 本实施例的抬升主体内设置有 四个相互隔离的风道, 抬升主体的顶面上设置四个相互隔离的进风口, 而四个 风道的出风口均与一个安装位连通。 当然, 也可以设置四个安装位, 每个安装 位分别与一个风道相连通。 在实际应用中, 并不限定安装位以及风道的数量。
[0063] 实施例六:

[0067] 风道的顶壁为中部凸起的曲面, 抬升主体的顶面为中部凹陷的曲面。 由于顶面 轮廓的特性, 气流无需借助康达效应也能贴着顶面流动, 然后通过第一引导结 构进入风道。 气流在风道内沿着风道流动, 流动至出风口位置吋, 在第二引导 结构的引导下, 继续吹向抬升主体的顶面, 进而, 气流可以在抬升主体顶面上 以及风道内不断地循环流动。
[0068] 抬升主体底面为波浪状曲面, 从而可增加底面与大气的接触面积, 使抬升结构 得到更大的抬升能力。 [0069] 实施例八:
[0070] 本实施例提供了一种抬升结构, 除以下的内容外, 本实施例的其他内容均与实 施例一相同。
[0071] 请参见图 10及图 11, 本实施例具有两个环形的风道 12、 两个环形的进风口 122 以及两个环形的出风口 123, 抬升主体 1的中间具有一幵口向上的凹槽 16。 其中 , 一个环形进风口 122位于抬升主体 1的外侧底部的边缘, 另一个进风口 122位于 该凹槽 16的内壁底部位置, 两个出风口 123位于抬升主体 1的顶面 13, 并且, 两 个出风口 123通过两个环形风道 12的底壁相隔。 本实施例的抬升主体 1的外周缘 以及凹槽 16内壁, 为抬升主体 1顶面 13与外界接触的区域, 该区域为气流提供了 较大的分布区域, 从而将气压较低的区域增大, 有利于增大抬升能力。
[0072] 进一步地, 抬升主体 1对应于两个环形风道 12底壁的位置设置有一形状的凹槽 1 7, 该凹槽 17的顶壁为向上凸起的曲面, 从而增加了抬升主体 1下方的受力面积 , 进一步地增大了抬升能力。
[0073] 实施例九:
[0074] 本实施例提供了一种抬升结构, 除以下的内容外, 本实施例的其他内容均与实 施例一相同。
[0075] 请参见图 12及图 13, 本实施例具有两个环形的风道 12、 一个环形的进风口 122 以及两个环形的出风口 123, 其中, 抬升主体 1具有一幵口向上的环形凹槽 18, 环形凹槽 18的中间区域以及边缘区域向上凸起, 所述环形的进风口 122位于环形 凹槽 18的底部, 一个环形的出风口 123位于抬升主体 1边缘区域的顶部内侧, 另 一个环形的出风口 123位于环形凹槽 18中间区域顶部的外侧。 本实施例的抬升主 体的环形凹槽 18的内壁, 为抬升主体 1顶面 13与外界接触的区域, 该区域为气流 提供了较大的分布区域, 从而将气压较低的区域增大, 有利于增大抬升能力。
[0076] 进一步地, 为了增加抬升主体 1下方的受力面积, 环形凹槽 18中间区域底部具 有一幵口向下的凹槽 19。
[0077] 实施例十:

[0081] 可以理解的是, 上述各实施例中风道 12的进风口 122以及出风口 123仅是为了便 于结合附图来描述说明, 在具体应用吋, 只要将用于吹风与吸风的装置的方向 调转, 则进风口 122即变成出风口, 而出风口 123即变为进风口。 而风道 12内的 具体形状, 即风道 12顶壁、 底壁的形状不受限制, 其仅是一个供气流传输的通 道, 只要其内部无阻塞, 无论其形状如何, 气流也能从进风口 122流出出风口 12 3。
[0082] 以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发明的 精神和原则之内所作的任何修改、 等同替换和改进等, 均应包含在本发明的保 护范围之内。
