具体实施方式
以下由特定的具体实施例说明本发明的实施方式，熟悉此技术的人士可由本说明书所揭露的内容轻易地了解本发明的其他优点及功效，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本说明书所引用的如“上”、“下”、“左”、“右”、“中间”等用语，亦仅为便于叙述的明了，而非用以限定本发明可实施的范围，其相对关系的改变或调整，在无实质变更技术内容下，当亦视为本发明可实施的范畴。
实施例1
如图1至图2所示，本发明实施例提供了一种可翻转式无轴推进器，包括机体结构1、铰接构件2、轮缘推进器3、固定基座支架4和基座绑带5，用以在水下潜行时，通过铰接构件2使轮缘推进器3可基于机体结构1沿前进方向转动展开或反向转动复位，以此在能够完成助推与取消助推功能的基础上，还可显著降低推进器发生缠绕的可能性；同时利用固定基座支架4和基座绑带5使轮缘推进器3可以绑缚穿戴在潜水者的四肢，提升了实用性。具体设置如下：
请参考图1至图2，所述推进器具有一个前进方向，所述机体结构1的内部开设有防水舱室，所述防水舱室的内部配置有相电连接的电池和控制电路，所述轮缘推进器3与所述防水舱室内部的电池和控制电路之间电性连接，用以以此通过电池和控制电路分别作为轮缘推进器3的电力基础及水下控制基础。
所述机体结构1的一端侧部固接有所述铰接构件2，所述轮缘推进器3为无轴环形推进器，且所述轮缘推进器3的一侧部固接有铰接连杆31，且所述轮缘推进器3通过所述铰接连杆31转接于所述铰接构件2，用以以此使轮缘推进器3可基于前进方向转动展开形成推进状态或是反向转动形成复位状态。
作为本实施例的一种优选方案，所述可翻转式无轴推进器还包括限位构件21，所述限位构件21固接于所述铰接构件2，且所述限位构件21位于所述轮缘推进器3自复位状态位转至推进状态位的切换路径上，用以通过限位构件21在轮缘推进器3转动至推进状态位的预设角度时，限制轮缘推进器3继续转动，以此使轮缘推进器3能够保持在推进状态的预设角度。
一种可选的实施方案，所述限位构件21由磁性材料制成，所述轮缘推进器3的对应部分由金属或铁磁性材料制成，用以通过轮缘推进器3与限位构件21之间的磁吸力有效增加轮缘推进器3在到达限位角度时的稳定性。
在推进器非工作状态下，所述轮缘推进器3的径向平面与前进方向的所处平面平行，即复位状态。当轮缘推进器3在水下开始工作时，通过控制电路电连接的按钮控制轮缘推进器3驱动其转子正转，利用轮缘推进器3自身的推力，使轮缘推进器3自动进入推进状态。当需要将轮缘推进器3重新复位时，通过按钮控制轮缘推进器3的转子反转，利用反向推力使其反向转动至复位状态。
上述方案利用了轮缘推进器3取代有轴螺旋桨，达到防缠绕和缩小水下推进器整体体积的效果，并采取轮缘推进器3可转动展开、复位的折叠方式使推进器更便于携带，同时由于轮缘推进器3前方无遮挡，从而达到较高推进效率。
作为本实施例的另一种优选方案，所述轮缘推进器3可以采用现有技术已知的“轴通量”式轮缘推进器，所谓“轴通量”轮缘推进器是指环形定子绕组产生的磁通量方向与转、定子间间隙延伸方向平行的环形推进器，从径向方向观察，“轴通量”轮缘推进器的转子和定子是沿轴向同轴并列分布。“轴通量”轮缘推进器相比“径通量”轮缘推进器的优点是更薄、体积更小。
作为本实施例的又一种优选方案，所述轮缘推进器3的进水口和出水口设装配有保护网，用以进一步降低发生缠绕的风险。
更为优选地，所述铰接构件2、所述限位构件21与所述机体结构1的外壳一体成型，用以减少装配流程，降低成本并提升整体稳定性。
请继续参考图1至图2，所述固定基座支架4可拆卸式固接于所述机体结构1的一侧部，且所述固定基座支架4在背离所述机体结构1的一侧部设有基座绑带5，用以使轮缘推进器3可以绑缚穿戴在潜水者的四肢。
优选的是，所述固定基座支架4有特定弧形结构设置，用以使得固定基座支架4绑缚在潜水者四肢时更符合人体工学，整体更为舒适。
实施例2
在实施例2中，对于与实施例1中相同的结构，给予相同的符号，省略相同的说明，实施例2在实施例1的基础上作出了改进，如图3所示，所述固定基座支架4与所述机体结构1之间为分体式结构，所述铰接构件2固接于所述固定基座支架4，所述轮缘推进器3通过所述铰接连杆31与所述铰接构件2之间转接相连，所述机体结构1与所述轮缘推进器3之间通过外置的电接线相连，用以使得重量较重的机体结构1可佩戴在潜水者身上，从而使潜水者在潜水时的四肢负重更小，活动更加轻便，提升了整体结构的功能实用性。
实施例3
在实施例3中，对于与实施例1和2中相同的结构，给予相同的符号，省 略相同的说明，实施例3在实施例2的基础上作出了改进，如图4至图5所示，所述机体结构1的侧部还装配固接有腰绑带6，用以通过腰绑带6绑缚于人体腰部，进而可将重量较重的机体结构1佩戴在潜水者的腰部，减少四肢负重。
虽然，上文中已经用一般性说明及具体实施例对本发明作了详尽的描述，但在本发明基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本发明精神的基础上所做的这些修改或改进，均属于本发明要求保护的范围。
