本发明实施例属于弹簧枪技术领域，涉及一种齿轮传动机构和水弹枪。
背景技术
水弹枪包括枪体、设于枪体内的动力机构、供弹机构和发射机构，其中，动力机构设有驱动装置和变速机构。如驱动机构设为动力电机，变速机构为通过齿轮多级变速的齿轮箱，动力电机驱动齿轮箱运行，齿轮箱驱动发射机构向枪体外发射水弹。
在相关技术中，水弹枪的齿轮箱未设置防反转机构，当水弹枪停止发射水弹后，齿轮箱内的齿轮会继续转动一预设的时长。由于齿轮之间为啮合连接，当齿轮箱内的齿轮空转时，齿轮箱产生较大的噪音，用户体验差。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的 要素。以下示例性实施例中所描述的实施方式并不代表与本发明实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明实施例的一些方面相一致的装置和方法的例子。
在本发明实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明实施例。在本发明实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
如图1和图2所示，齿轮传动机构包括与驱动装置30连接的齿轮组，齿轮组设有至少一传动齿轮组件10。驱动装置30与齿轮组连接，并通过齿轮组调节输出转速及扭矩。驱动装置30与传动齿轮组件10的动力传递可通过直接传递方式或间接传递方式进行传递。在一实施方式中，驱动装置30的输出轴直接固定于传动齿轮组件10的转轴上。在一实施方式中，驱动装置30的输出轴上安装有驱动齿轮，该驱动齿轮与传动齿轮组件10啮合连接。在一实施方式中，驱动装置30的输出轴与传动齿轮组件10的转轴通过离合器组件插接连接。驱动装置30与齿轮组的连接方式不同，可适用于不同的应用场景，实用性好。
在一实施例中，齿轮传动机构还包括防反转组件20，防反转组件20弹性抵接至其中一传动齿轮组件10。齿轮组包括一个或一个以上的传动齿轮组件10，当齿轮组的传动齿轮组件10为一个时，防反转组件20弹性抵接于该传动齿轮组件10。当齿轮组设有一个以上的传动齿轮组件10时，传动齿轮组件10之间啮合连接。防反转组件20弹性抵接于其中一传动齿轮组件10。相应地，在防反转组件20的预压力作用下，整个齿轮组均能在驱动装置30停止动力输入后停止转动。
防反转组件20弹性抵接于传动齿轮组件10，还用于防止传动齿轮组件10方向转动。其中，当传动齿轮组件10沿第一方向转动时，防反转组件20弹性抵紧传动齿轮组件10，传动齿轮组件10绕轴线转动并推动防反转组件20沿轴线方向移动。当传动齿轮组件10沿与第一方向相反的第二方向转动时，防反转组件20与传动齿轮组件10相互抵靠并锁定传动齿轮组件10的转动位置。
齿轮传动机构设有弹性抵接于传动齿轮组件10的防反转组件20，传动齿轮组件10仅能沿第一转动方向转动，齿轮组的转动方向稳定性好。防反转组件20与传动齿轮组件10互相抵靠锁定，阻止齿轮组的反向转动，其制动效果好，传动齿轮组件10的停止位置可控性强。防反转组件20弹性抵接于传动齿轮组件10，两者之间具有预压力。在驱动装置30停止动力输入后，传动齿轮组件10自预压力的作用下停止转动，齿轮传动机构不会空转，结构紧凑，噪音小。
防反转组件20弹性抵接于传动齿轮组件10，传动齿轮组件10沿第一方向转动时，传动齿轮组件10推动防反转组件20弹性伸缩。如防反转组件20沿传动齿轮组件10的径向、轴向或与传动齿轮组件10的轴线向倾斜的方向弹性抵接至传动齿轮组件10，以使传动齿轮组件10按第一方向转动时，能推动防反转组件20弹性伸缩。传动齿轮组件10按第二方向转动时，防反转组件20抵紧传动齿轮组件10。
如图3和图4所示，在一实施例中，防反转组件20沿平行于传动齿轮组件10的轴线方向弹性伸缩。传动齿轮组件10通过驱动装置30驱动转动，传动齿轮组件10绕自身的轴线转动。防反转组件20沿传动齿轮组件10的轴线方向弹性抵接于传动齿轮组件10的表面，其弹性作用力方向垂直于传动齿轮组件10转动平面。防反转组件20对传动齿轮组件10之间动力传递影响小，传动齿轮组件10之间的啮合平衡性好，动力传递稳定。
在一可选地实施例中，防反转组件20滑设于转轴上，转轴与传动齿轮组件10的轴线共线。转轴可设为安装于一固定部位上的柱状结构，也可设为传动齿轮组件10的齿轮轴12。防反转组件20与转轴之间设有至少一配合平面，以使防反转组件20仅能沿转轴的轴向移动，例如安装防反转组件20的转轴设有相对平行的两导向面，或转轴设为花键轴。防反转组件20沿传动齿轮组件10的轴线方向滑动，其与传动齿轮组件10的抵接部位均匀分布，可使传动齿轮组件10受力均匀。如，防反转组件20设有两个抵接部位，两抵接部位分别设为转轴的相对两侧。两抵接部位抵接至传动齿轮组件10，以使传动齿轮11所受的压紧力对称分布。防反转组件20与传动齿轮组件10的轴线共线，使得传动齿轮组件10的轴向受力均匀，传动齿轮组件10转动平稳。
在一实施例中，防反转组件20包括防转件21和弹性抵接于防转件21的 弹性件22，弹性件22推动防转件21弹性抵接于传动齿轮组件10。防转件21为刚性结构，其抵接至传动齿轮组件10以使弹性力作用于传动齿轮组件10的表面。弹性件22可设为弹簧类结构或由弹性材料制成，弹性件22具有预设形变量，以使防转件21在弹性力作用下与传动齿轮组件10保持抵紧状态。
如图5所示，防转件21至少部分凸处以形成抵接部位，该抵接部位与传动齿轮组件10相互抵接。当传动齿轮组件10按第二方向转动时，该抵接部位反向抵靠至传动齿轮组件10，以避免传动齿轮组件10方向旋转。在一可选的实施例中，防转件21包括主体部211和凸设于主体部211的至少一止动凸台212，弹性件22弹性抵接于主体部211，止动凸台212抵接至传动齿轮11。当传动齿轮组件10沿第一方向转动时，传动齿轮组件10抵靠至推动止动凸台212沿轴线方向伸缩运动，其中止动凸台212至少部分接触面设为斜面。
在一可选的实施方式中，主体部211套设在于转轴外，主体部211可沿转轴直线移动。在主体部211的端面凸设有两止动凸台212，两止动凸台212沿顺时针或逆时针均匀分布于主体部211上。当传动齿轮组件10沿第一方向转动时，两止动凸台212贴合于传动齿轮组件10的表面，并在传动齿轮组件10的推动下沿转轴的轴线方向移动。当传动齿轮组件10沿第二方向转动时，传动齿轮组件10至少部分抵靠至两止动凸台212，以使两止动凸台212限定传动齿轮组件10的转动，从而防止齿轮组反向传动。可以理解，所述止动凸台212的数目也可以为一个、三个、四个等其他数目。
在一可选的实施方式中，止动凸台212包括斜坡状的滑动面2121和位于滑动面2121一端的止动面2122。当传动齿轮组件10沿第一方向转动时，传动齿轮组件10与滑动面2121滑动抵接。当传动齿轮组件10沿与第一方向相反的第二方向转动时，止动面2122锁定传动齿轮组件10。
滑动面2121与止动面2122构成一夹角或者两者的延长面构成一夹角，例如，滑动面2121与止动面2122构成一锐角。当主体部211上设置两个及以上的止动凸台212时，滑动面2121沿顺时针或逆时针分布，以使传动齿轮组件10沿滑动面2121滑动。止动面2122位于滑动面2121的末端，并与主体部211的端面之间形成台阶结构。当传动齿轮组件10朝向第二方向转动时， 传动齿轮组件10抵靠至止动面2122，以锁定传动齿轮11的转动位置。其中，传动齿轮组件10的端面设有与止动凸台212相匹配的凸台结构或凹槽结构。
如图2和图3所示，在一实施例中，传动齿轮组件10包括齿轮轴12以及设置于齿轮轴12上的齿轮11，齿轮11随齿轮轴12转动。齿轮轴12的两端安装于固定的物体上，如安装于齿轮箱的箱壁处。传动齿轮组件10还包括凸设于齿轮11一端或齿轮轴12上的防转部13，防反转组件20弹性抵接于防转部13。防转部13设于齿轮11的端面上或者设于齿轮轴12的台阶面处或者设于齿轮轴12上的凸台处，防反转组件20弹性抵接于齿轮11或齿轮轴12并与防转部13相配合。
如图3和图6所示，当传动齿轮组件10沿第一方向转动时，防反转组件20沿防转部13的表面滑动，防转部13推动防反转组件20沿传动齿轮组件10的轴向移动。当传动齿轮11沿与第一方向相反的第二方向转动时，防转部13抵靠至防反转组件20以锁定传动齿轮组件10的转动位置。
在一可选地实施例中，防反转组件20套设于齿轮轴12并沿齿轮轴12滑动，防转件21抵靠至传动齿轮组件10。防转部13为设于齿轮11的端部并朝外凸出的至少一防转凸台。防转凸台与止动凸台212的结构相似，防转凸台设有斜坡状的引导面131和位于引导面131一端的锁止面132。引导面131与锁止面132相交呈一夹角或两者的延伸面相交呈一夹角。
在一可选的实施方式中，防转件21设有正对设置的两止动凸台212，防转部13设为与两止动凸台212相对应的两防转凸台。齿轮11带动两防转凸台向第一方向转动时，引导面131贴合于滑动面2121并推动防转件21沿轴线向外移动，直至防转凸台的顶部抵靠与止动凸台212的顶部，防转件21移动至最大位移量处。齿轮11继续转动直至防转凸台与止动凸台212分离，防转件21的端面与防转凸台的顶面相互接触。齿轮11继续转动，防转件21始终弹性抵接于齿轮11的端面处，直至防转凸台与防转件21的另一止动凸台212相对移动，并依次循环。齿轮11带动两防转凸台向第二方向转动时，防转凸台的锁止面132抵靠至止动凸台212的止动面2122，防反转组件20阻挡齿轮11继续转动，以锁定齿轮11的位置。
防反转组件20与传动齿轮组件10之间相互配合，限定传动齿轮组件10的反转，传动齿轮组件10的停止及时，避免齿轮组空转及反转。
如图1和图2所示，在一实施例中，防反转组件20设置于齿轮组中靠近驱动装置30的传动齿轮组件10处。当齿轮组为多级齿轮啮合连接形成的变速结构时，特别是减速齿轮组，其位于输出一端的传动齿轮组件10所输出的转速小、扭矩大，而靠近驱动装置30一端的传动齿轮组件10所输出的转速大、扭矩小。将防反转组件20抵靠于靠近驱动装置30的传动齿轮组件10处，相应减小防反转组件20作用于传动齿轮组件10的弹性力。同时传动齿轮组件10向第二方向转动时，冲击在防反转组件20的冲击力相应减小，降低防反转组件20的材料性能要求，防反转组件20的使用寿命长。
在一可选地实施例中，齿轮组包括与驱动装置30啮合的第一齿轮组件14、与第一齿轮组件14啮合的第二齿轮组件15及与第二齿轮组件15啮合的第三齿轮组件16，防反转组件20弹性抵接至第一齿轮组件14。即第一齿轮组件14为与驱动装置30连接的传动齿轮组件10。
驱动装置30设有输出齿轮11，输出齿轮11与第一齿轮组件14啮合连接。例如，输出齿轮11设为锥形齿轮，第一齿轮组件14包括齿轮轴12、安装于齿轮轴12的齿轮11，齿轮11包括齿体部112、设于齿体部112一侧的斜齿部111和设于齿体部112另一侧的直齿部113。其中齿体部112、斜齿部111和直齿部113构成本体部，防转凸台凸设于斜齿部111朝外的一侧。输出齿轮11与斜齿部111啮合连接，防反转组件20滑设于齿轮轴12且弹性抵接于斜齿部111，防反转组件20的止动凸台212与防转凸台相匹配。
直齿部113凸设于齿体部112并与第二齿轮组件15啮合连接，第二齿轮组件15与第三齿轮组件16啮合连接，其中，第一齿轮组件14、第二齿轮组件15及第三齿轮组件16之间按预设的传动比啮合连接。
第三齿轮组件16包括支撑轴161和安装于支撑轴161的功能齿轮162。功能齿轮162包括与第二齿轮组件15啮合连接的啮合部1621及凸设于啮合部1621的功能部1622，其中功能部1622根据不同的场景推动相应地机构运行。如功能部1622设为与齿条啮合连接齿轮结构，或在功能部1622上设有部分轮齿。或者功能部1622设为多级台阶，每一级台阶的外周壁上设有部分轮齿等。
如图7所示，本发明实施例还提供了一种上述齿轮传动机构在水弹枪中的应用场景。
在一实施例中，水弹枪包括枪体40、安装枪体40内的发射机构60、向发射机构60提供水弹的供弹机构50和如上所述的齿轮传动机构。齿轮传动机构用于驱动发射机构60。其中发射机构60包括活塞组件61和弹性抵接于活塞组件61的弹性组件62，齿轮传动机构与活塞组件61驱动连接。如，第三齿轮组件16的功能部1622与活塞组件61驱动连接，以使活塞组件61压缩弹性组件62。
当齿轮传动机构驱动发射机构60压缩至预设位置时，发射机构60用于推动水弹沿枪体40移动，以使水弹向枪体40外射出。活塞组件61滑设于枪体40的弹道中，供弹机构50将水弹补充于该弹道中。当活塞组件61压缩到预设位置时，齿轮传动机构与活塞组件61分离，以使活塞组件61在弹性组件62的弹性力作用下复位，在复位过程中，活塞组件61推动水弹移动并为水弹提供动能。相应地，水弹沿枪体40的弹道滑动，直至从枪口中射出。齿轮传动机构采用多级齿轮11传动，以减低齿轮组的输出转速，加大输出扭矩，以使活塞组件61能承受较大的预紧力，提高水弹的发射速度。
在一可选地实施方式中，活塞组件61包括一级活塞齿条组件611和滑设于一级活塞齿条组件611的二级活塞齿条组件612。其中，第三齿轮组件16的功能部1622包括一级轮齿和二级轮齿，一级轮齿和二级轮齿仅分布于功能部1622的部分表面，如分布于功能部1622的三分之一、四分之一的圆周面上。一级轮齿与一级活塞齿条组件611相匹配，二级轮齿与二级活塞齿条组件612相匹配。
当一级轮齿与一级活塞齿条组件611啮合连接时，活塞组件61整体移动直至二级轮齿与二级活塞齿条组件612啮合连接。二级轮齿驱动二级活塞齿条组件612继续压缩弹性组件62，同时，一级活塞齿条组件611在自动复位。当功能部1622继续转动至未设置二级轮齿的表面时，二级活塞齿条组件612在弹性组件62的弹性力驱动下快速复位，同时，二级活塞齿条组件612推动水弹沿弹道移动。活塞组件61设置多级增压，压缩行程加长，使得弹性组件62的压缩力大，作用于水弹的弹性力增大，用户体验好。
以上仅为本发明实施例的较佳实施例而已，并不用以限制本发明实施例，凡在本发明实施例的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明实施例保护的范围之内。
