所述限位凸台 50位于所述第一运动轨道 N1的外围, 且部分落入所述第 二运动轨道 N2内 (如图 7所示)。 本实施例中, 所述第二运动轨道 N2为圓弧 轨道。 当然, 在其他实施例中, 所述第二运动轨道 N2也可为圓周轨道。 具体 的, 所述转轴 11转动的过程中, 当所述第一拨动部 32与所述第二拨动部 42 的一侧边接触时, 所述第一拨动部 32与所述第二拨动部 42—起随所述转轴 11的转动而转动, 直至所述第二拨动部 42与所述限位凸台 50接触, 所述第 二拨杆 40停止转动, 而所述第一拨动部 32继续围绕所述转轴 11的轴心转动 并再次靠近所述第二拨动部 42; 当所述第一拨动部 32与所述第二拨动部 42 的另一侧边接触时, 所述转轴 11、 所述第一拨杆 30及所述第二拨杆 40停止 转动, 进而使得所述第一拨杆 30转动的角度大于 360度并且小于 720度。
更进一步的, 当所述转轴 11转动, 带动所述第一拨杆 30及所述第二拨杆 40转动, 当所述第二拨杆 40转动至所述第二拨动部 42与所述限位凸台 50接 触时, 所述第二拨杆 40由于所述限位凸台 50的限位作用而停止运动, 所述第 一拨杆 30继续转动直至与所述第二拨杆 40接触并停止转动。此时, 所述转轴 11沿第二方向 B转动, 从而带动所述第一拨杆 30及所述第二拨杆 40沿所述 第二方向 B转动, 直至所述第二拨杆 40的第二拨动部 42再次与所述限位凸 台 50接触, 从而所述第二拨杆 40停止运动, 所述第一拨杆 30继续围绕所述 转轴 11的轴心转动并再次靠近所述第二拨杆 40, 直至所述第一拨杆 30与所 述第二拨杆 40接触。 此时所述转轴 11再次沿所述第一方向 A转动, 从而带 动所述第一拨杆 30及第二拨杆 40沿所述第一方向 A转动, 以此循环。 通过 所述转轴 11的换向转动,进而使得所述第一拨杆 30及第二拨杆 40换向转动。
本实施例中, (以图 5中视角为准), 所述第二方向 B与所述第一方向 A 相反。 具体的, 所述第一方向 A为逆时针方向, 所述第二方向 B为顺时针方 向。 当然, 在其他实施例中, 所述第一方向 A也可为顺时针方向, 所述第二 方向 B也可为逆时针方向。
进一步的,所述第一拨动部 32至所述转轴 11中心的距离小于所述限位凸 台 50至所述转轴 11中心的距离, 从而使得所述第一拨杆 30不受所述限位凸 台 50的限位作用, 进而当所述第二拨杆 40受到所述限位凸台 50限位作用停 止转动时, 所述第一拨杆 30能够继续绕所述转轴 11的轴心转动。 当然, 在其 他实施例中, 也可通过定义所述限位凸台 50在所述收容槽 22a中的高度与所 述第一拨动部 32的高度关系来使得所述第一拨杆 30不受所述限位凸台 50的 限位作用。
更进一步的,所述第二拨动部 42至所述转轴 11中心的距离大于所述限位 凸台 50至所述转轴 11中心的距离, 从而使得所述第二拨杆 40在运动时, 受 到所述限位凸台 50的限位作用,从而使得所述第二拨杆 40的运动位置得到限 制。 当然, 在其他实施例中, 同样可通过定义所述第二拨动部 42与所述限位 凸台 50的高度关系, 从而也可达到本实施例中的限位效果。
所述限位装置 1还包括一个锁紧螺母 70, 所述锁紧螺母 70设于所述转轴 11上。 具体的, 所述锁紧螺母 70与所述第三连接部 11c螺紋连接, 所述锁紧 螺母 70用于提供轴向预紧力防止所述第二拨杆 40从所述第一拨杆 30上滑脱。 电机转子组件 10固定连接。

请参阅图 8, 所述负载 2转动连接于所述限位装置 1上, 且所述限位装置 1带动所述负载 2转动。 本实施例中, 所述负载 2为摄像头组件。 当然, 在其 他实施例中, 所述负载 2也可为微型电脑或投影设备等。 具体的, 所述负载 2 包括摄像头 2a及连接杆 2b,所述摄像头 2a上设有第一转动轴 211和第二转动 轴 212 , 所述连接杆 2b的两端分别转动连接于所述第一转动轴 211及第二转 动轴 212上。 当转动所述连接杆 2b时, 即可带动所述摄像头 2a转动。 所述转 动杆 13远离所述外壳 12的一端转动连接所述第一转动轴 211上,当所述电机 转子组件 10转动时, 所述转动杆 13带动所述第一转动轴 211转动,从而带动 所述摄像头 2a转动。
进一步的, 当将所述飞行器 100应用于航拍设备上时, 所述转轴 11带动 所述第一拨杆 30沿所述第一方向 A转动, 从而使得所述转动杆 13带动所述 负载转动。 当所述第一拨杆 30及第二拨杆 40转动至所述第二拨杆 40与所述 限位凸台 50接触时, 所述第二拨杆 40停止转动, 所述第一拨杆 30继续绕所 述转轴 11的轴心转动, 直至所述第一拨杆 30与所述第二拨杆 40接触, 从而 所述转轴 11及第一拨杆 30停止转动。 则此时所述负载 2停止转动,从而当所 述第一拨杆 30转动的总角度大于 360度并且小于 720度时,所述摄像头 2a在 所述转动杆 13的带动下的转动总角度也大于 360度并且小于 720度, 进而使 得所述摄像头 2a的拍摄角度更广。 此外, 由于所述第一拨杆 30在转动时沿所 述第一方向 A转动至少一圈,从而使得所述摄像头 2a的拍摄方向为同一方向, 则避免了当转动一周后反方向返回造成拍摄景象重复, 从而使得摄像头 2a拍 摄的景象更全面。
本发明提供的限位装置, 设置转轴、 第一拨杆及第二拨杆, 通过转轴带动 第一拨杆及第二拨杆转动, 并设置限位凸台,使得第二拨杆由于限位凸台的限 位作用而停止转动, 而第一拨杆继续转动至与第二拨杆接触并停止转动,从而 使得第一拨杆的转动角度大于 360度并且小于 720度。
以上所述是本发明的优选实施方式,应当指出, 对于本技术领域的普通技 术人员来说, 在不脱离本发明原理的前提下, 还可以做出若干改进和润饰, 这 些改进和润饰也视为本发明的保护范围。
