具体实施方式
本发明的核心在于，提供一种旋转式腕投，以根据使用者需求调整投影模块的投影方向。
为了使本技术领域的人员更好地理解本发明方案，下面结合说明书附图来对本发明作进一步的详细说明。
请参见图1和图2，其中，图1示出了本发明所提供的腕投具体实施例的结构示意图，图2示出了图1的分解结构示意图。
结合图1和图2可知，本发明所提供的旋转式腕投包括投影模块1、腕带2和旋转机构3；其中，投影模块1包括外壳以及封装于外壳内的影像存储/采集模块和投射模块，投射模块用于将存储/采集的影像信息由外壳的投影口1a投射至外部环境；投影模块1的外壳和腕带2通过旋转机构3连接，旋转机构3的旋转轴32与投影口1a的开口方向垂直设置。
使用者旋转投影模块1，使之相对于腕带2绕旋转机构3的旋转轴32旋转，投影口1a也随之在垂直于旋转轴32平面内360°(度)旋转，也就是说，投影模块1的方向可调，以便使用者根据实际需求将影像投射至墙壁或手臂等任何可作为投影面等部件上。因此，与传统的腕投相比，旋转式腕投极大地提高了客户体验。
需要说明的是，投影模块1的影像存储/采集模块、投射模块以及外壳三者的工作原理及连接关系于现有技术完全相同，本领域技术人员基于现有技术完全可以实现，故而本文在此仅对旋转机构3的具体结构及工作原理加以详述。
请参见图3至图6，其中，图3示出了旋转机构3的第一种具体实施例的结构示意图，图4示出了图3的透视结构示意图，图5示出了图4的A处局部放大示意图，图6示出了具有图3中所示旋转机构3的腕投整体透视结构示意图。
结合图4和图6所示，本具体实施例所提供的旋转机构3包括底座31、外棘轮33、滑块34和复位弹簧35，其中，底座31与腕带2固定连接，外棘轮33与投影模块1固连并绕旋转轴32可转动地安装于底座31，滑块34可滑动地安装于底座31并具有与外棘轮33啮合的轮齿34a，复位弹簧35预压装于底座31和滑块34间，复位弹簧35的预压装力足以将滑块34的轮齿34a压紧于外棘轮33的齿槽内。为了便于更好地理解本具体实施例中旋转机构3的具体结构，请一并参见图3。
详细地，结合图4和图5，底座31开设有相互连通的第一滑槽31a和第二滑槽31b，外棘轮33的齿顶圆直径小于第一滑槽31a的槽宽且大于第二滑槽31b的槽宽，第二滑槽31b的槽宽大于旋转轴32的外圆直径，外棘轮33可转动地安装于第一滑槽31a内，旋转轴32与外棘轮33同轴设置并且其一端部与外棘轮33固连另一端由第二滑槽31b伸出后与投影模块1固连。本文在此所述槽宽是指第一滑槽31a和第二滑槽31b在垂直于旋转机构3的旋转轴32平面内的长度。
需要说明的是，为了防止外棘轮33的摩擦磨损，本具体实施例中第一滑槽31a的槽宽大于外棘轮33的齿顶圆直径，其槽深大于外棘轮33的厚度。
进一步地，如图4所示，在垂直于旋转机构3的旋转轴32的截面内，第二滑槽31b的截面形状包括两条平行线段和与两条平行线段相切的圆弧，圆弧与外棘轮33同心且半径小于外棘轮33的齿顶圆半径。
如此设置，外棘轮33约2/3轮齿3周向位于第一滑槽31a内，投影模块1和底座31间恰是通过外棘轮33连接，从而可保证投影模块1和底座31两者的连接可靠性。
继续参见图4可知，滑块34沿第一滑槽31a可滑动地安装于底座31主体，压板36通过螺栓组件固连于底座31主体的第一滑槽31a的槽口处，复位弹簧35预压装于压板36和滑块34间，复位弹簧35的预压装力足以将滑块34的轮齿34a压紧于外棘轮33的齿槽内。
此外，如图4所示，为了提高复位弹簧35的工作稳定性和连接可靠性，本具体实施例中压板36开设有定位盲孔，复位弹簧35的一端部插装于定位盲孔内，另一端部伸出定位盲孔并与滑块34相抵压紧。
进一步地，如图5所示，压板36包括压紧部36a和罩盖部36b，其中，压紧部36a位于第一滑槽31a内，复位弹簧35预压装于压紧部36a和滑块34间；罩盖部36b位于第二滑槽31b内并沿滑槽方向延伸至罩盖复位弹簧35和滑块34，用于定位复位弹簧35的定位盲孔开设于压紧部36a。
压板36设置罩盖部36b可防止复位弹簧35因外力而意外脱离底座31造成的安全事故， 从而保证旋转机构3整体结构的可靠性和工作安全性。
本具体实施例所提供的旋转机构3的工作过程为：初始状态下，复位弹簧35的预紧力将滑块34的轮齿34a压紧于外棘轮33的齿槽内；旋转投影模块1，外棘轮33随投影模块1绕旋转轴32的轴线转动，外棘轮33推动滑块34克服复位弹簧35的弹性力，使滑块34的轮齿34a沿外棘轮33的齿廓线的齿根部滑动至齿顶部；继续旋转投影模块1，外棘轮33继续转动，在复位弹簧35的弹性力作用下，滑块34的轮齿34a沿外棘轮33的齿廓线滑动至与外棘轮33的轮齿34a完全啮合。重复上述步骤直至投影模块1的投影口到达理想位置。
这种旋转机构3不仅能实现复位弹簧35与腕带2相对位置的调整，而且还可通过轮齿34a间的啮合使滑块34和外棘轮33两者锁定于特定位置，当外力不足以克服复位弹簧35的弹性力时投影模块1不会相对于腕带2转动。
需要说明的是，本具体实施例中，复位弹簧35具体为圆柱压缩弹簧，可以理解，在满足将滑块34预压装至轮齿34a与外棘轮33的轮齿3完全啮合及装配工艺要求的基础上，复位弹簧35还可以为本领域技术人员惯用的其他弹性元件或弹性结构。
此外，复位弹簧35的数量为两个，且两个复位弹簧35相对于滑块34的轮齿34a左右对称设置，以便滑块34的轮齿34a受到的弹性力均布，以保证其滑动的平稳性和可靠性。
本发明还提供旋转机构3的另外两种具体实施例，请参见图7和图8，其中，图7示出了旋转机构的第二种具体实施例的轴向剖视结构示意图，图8示出了旋转机构的第三种具体实施例的轴向剖视结构示意图。需要说明的是，后两种具体实施例中对相同功能组件采用同一组件名称和附图标记表示。
结合图7和图8可知，旋转机构3的后两种具体实施例中，投影模块1和底座31相抵，并通过相适配的阶梯孔和阶梯旋转轴37可相对转动地连接，其中，阶梯孔开设于底座31，阶梯旋转轴37的小轴段贯穿阶梯孔的小孔段并与投影模块1固连，并在阶梯旋转轴37的轴肩与底座31的配合面间预压装弹性元件。
旋转投影模块1，旋转阶梯轴随投影模块1转动，当达到预定位置后，投影模块1和底座31间摩擦阻尼使两者锁定，而腕带2固定连接于底座31上，继而实现了投影模块1和腕带2相对位置的调整。此外，这种旋转式腕投通过弹性元件补偿了投影模块1和底座31刚性滑动摩擦造成的磨损量，提高了旋转式腕投整体的使用寿命。
详细地，如图7所示，旋转机构3的第二种具体实施例中，底座31开设有三段阶梯通孔31c，阶梯旋转轴37和三段阶梯通孔31c间隙配合且通过紧固件(螺钉39)与投影模块1固连，三段阶梯通孔31c的大孔孔底限定了阶梯旋转轴37的轴向位移，圆柱压缩弹簧38 套装于阶梯旋转轴37的小轴段，并预压装于三段阶梯通孔31c的小孔孔底和阶梯旋转轴37的轴肩间。
具体地，本实施例中，弹性元件具体为圆柱压缩弹簧38，可以理解，在满足产生轴向压缩变形功能及装配工艺要求基础上，弹性元件亦可为橡胶环等本领域常用的弹性元件。
此外，本具体实施例中，阶梯旋转轴37和投影模块1通过紧固件(螺钉39)连接，通过调整紧固件与投影模块1的旋合长度，即可调整圆柱压缩弹簧38的压缩量。当然，在满足预压装弹性元件功能及装配工艺基础上，阶梯旋转轴37和投影模块1可以焊接、粘接后铆接等方式固连。
如图8所示，旋转机构3的第三种具体实施例中，底座31开设有两段阶梯盲孔31d，阶梯旋转轴37通过紧固件(螺钉39)固连于投影模块1，且其大轴段位于两段阶梯盲孔31d的小孔段；压板环39具有间隙地套装于阶梯旋转轴37的小轴段，并固连于两段阶梯盲孔31d的大孔段，以限定阶梯旋转轴37的轴向位移；硅胶38＇通过压板环310预压装于阶梯旋转轴37的大轴段与压板环39和/或底座31的配合面间。
需要说明的是，本具体实施例中弹性元件具体为硅胶38＇。当然，在满足装配工艺要求的基础上，弹性元件亦可为橡胶等在外载荷作用下发生弹性变形的元件。
显然，与旋转机构3的第一种具体实施例所提供的旋转机构3相比，后两种旋转机构3结构简单、制造成低。
以上所述仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内所作的任何修改、等同替换、改进等，均包含在本发明的保护范围内。
