请参阅图1，本发明实施方式的拨弹机构10可应用于射击装置12，射击装置12是一种将射击弹射出的设备。所述射击弹为任何颗粒状的弹体，其中，所述射击弹可以为球体或者立方体，另外，所述射击弹可以为形态始终不改变的弹体，例如金属弹体或塑料弹体，在某些情况中，所述射击弹可以为形态可改变的弹体，即在射击弹在被射击装置12射出之前是颗粒状的固体，在被射击装置射出并击中目标对象之后可以变为液体或者气体，例如水弹或者烟雾弹。射击装置12可以用于娱乐、竞技等各方面，以满足用户的不同需求。
在图1的示例中，射击装置12可以安装在可移动平台(未示出)上，进一步地，所述射击装置12可以通过支架13安装在可移动平台上。其中，所述支架13可以为云台，所述云台可以为三轴、两轴或者单轴的云台。可移动平台可以为在外力作用下移动或者通过自身配置的动力系统移动的设备。可选地，所述可移动平台可以为无人机，其中，所述无人机可以为无人地面机器人、无人 飞行器或者无人船。射击装置12设置在可移动平台上，在可移动平台移动的过程中，射击装置12可以在移动状态下将射击弹射出。另外，可移动平台控制所述云台的姿态以调节射击装置12的射击方向。
请参阅图2-图13，射击装置12可以包括弹仓70、拨弹机构10和枪管80，其中，射击装置12还包括射击机身15，所述弹仓70、拨弹机构10和枪管80设置在所述机身15上，所述弹仓70用于存储射击弹，其中，所述弹仓70上设置出弹通道71，其中，存储在弹仓70中的射击弹从出弹通道71进入拨弹机构10。拨弹机构10将从出弹通道71进入的射击弹推送到枪管80，然后射击装置12将射击弹从枪管80射出。
下面将详细介绍拨弹机构10的具体机构，拨弹机构10包括动力部件14、传动组件16、拨弹轮18和拨弹盘20，其中，拨弹盘20用于收容从弹仓70进入拨弹机构10的射击弹，具体地，拨弹盘20用于收容从所述出弹通道进入拨弹机构10的射击弹。拨弹轮18安装在拨弹盘20上，拨弹轮18上设置有拨弹部22。具体地，拨弹部18沿拨弹轮18的周向设置。
拨弹机构10工作时，动力部件14驱动传动组件16运动，传动组件16运动时带动拨弹轮18单向转动以使拨弹部22将收容在拨弹盘20的射击弹推送到出弹口24，射击弹从出弹口24进入枪管80，然后射击装置12将射击弹从枪管80射出。
如此，单向转动的拨弹轮18使拨弹部22有序地将射击弹推送到出弹口24，防止射击装置12在工作时出现射击弹漏发或多发等不良现象。
请结合图4和图6，动力部件14可以任何输出动力的部件，例如为伺服电机、步进电机等电动元件或者在物理形态改变时能对外输出动力的部件，其中，所述在物理形态改变时能对外输出动力的部件可以为弹性部件，进一步地，所述弹性部件可以包括弹簧、弹片等，传动组件16为任何能够直接或者间接地接收动力部件14输出的动力之后产生运动的部件，例如所述传动组件16可以包括齿轮、推杆和导轨等元件。
请结合图12，拨弹轮18转动地设置在拨弹盘20内，拨弹轮18上设置拨弹部22，进一步地，所述拨弹部22沿所述拨弹轮18的周向均匀设置。在某些实施例中，所述拨弹轮18为齿轮状，所述拨弹轮18包括轮毂26和轮齿28，轮齿28沿轮毂26的周向间隔设置在轮毂26上，相邻的两个轮齿28之间限定出拨弹部22，即相邻的两个轮齿28之间的收容槽可以为拨弹部22。
在某些实施例中，拨弹部22呈弧形槽，拨弹部22的尺寸可略大于射击弹的尺寸以容置射击弹，具体地，所述射击弹从弹仓70进入拨弹盘20之后，射击弹会被拨弹部22所定位，随着拨弹部22的转动而转动。其中，拨弹部22的数量为可以为多个，例如5、6、7、8、10个等等，在这里不做具体的限定。
请参阅图6及图8，拨弹盘20包括底壁30和自底壁30的周缘延伸的侧壁32，底壁30和侧壁32围成有容弹槽34，拨弹轮18容置于容弹槽34的中间位置，出弹口24开设在底壁30上，在某些实施例中，所述出弹口可以开设在所述侧壁32上。出弹口24位于拨弹轮18径向一侧，出弹口24的尺寸略大于射击弹的尺寸，使得射击弹在随着拨弹部22转动时进入出弹口24内，具体地，当拨弹部22转动时，带动射击弹运动置出弹口24，在重力作用下，所述射击弹进入出弹口24。容弹槽34的深度例如大于射击弹的直径，而小于射击弹的两倍直径，这样使得容弹槽34可容置一层射击弹，有利于拨弹轮20推动射击弹。
在某些实施方式中，传动组件16在动力部件14的驱动下周期性运动，其中，当传动组件16周期性运动时带动拨弹轮18单向转动以使拨弹部22在每一个周期内将收容在拨弹盘20中的一个射击弹推送到出弹口24。具体地，拨弹部22的尺寸可略大于射击弹的尺寸以仅仅容置一颗射击弹，在射击装置12进行一次发射操作时，即在一个周期内，传动组件16在动力部件14的驱动下运动，所述传动组件16运动时带动所述拨弹轮18单向转动预设角度以使所述拨弹部22将容置的一颗射击弹推送到出弹口。
如此，拨弹部22在一个周期内将一个射击弹推送到出弹口24，这样可以 避免射击装置12在一个发弹周期内同时将多个射击弹发射出去或者出现漏发射击弹的现象。需要指出的是，所述周期为射击装置12完成一次射击操作的时间。
请参阅图8-图10，在某些实施方式中，拨弹机构10包括单向转动件36，传动组件16通过驱动单向转动件36来带动拨弹轮18单向转动。如此，单向转动件36可以实现拨弹轮18单向转动的效果。
单向转动件36可以被限定为任何能够实现单向传动的部件，其中，所述拨弹轮18单向转动的方向与单向转动件36单向传动的传动方向相同，例如所述单向传动部件36可以为单向轴承，拨弹盘20的轮毂26可以套设在单向轴承的外圈上，实现固定连接。单向轴承的内圈和外圈在第一方向可以自由相对转动，单向轴承不能在第一方向上实现传动，而单向轴承的内圈和外圈在与第一方向相反的第二方向是相对锁死，不能相对转动的，可以实现沿第二方向的单向传动，即所述第二方向为拨弹轮18单向转动的方向。
请再次参阅图6-图8，在某些实施方式中，传动组件16包括驱动单向转动件36的第一传动部件38；第一传动部件38在动力部件14的驱动下以参考轴线L为转动轴线沿第一周向方向R1和背离第一周向方向R1的第二周向方向R2运动，第一传动部件38运动时带动拨弹轮18单向转动以使拨弹部22将收容在拨弹盘20的射击弹推送到出弹口24。
具体地，在一个周期内，动力部件14通过直接或者间接地驱动第一传动部件38转动沿第一周向方向R1和第二周向方向R2转动，当第一传动部件38沿第一周向方向R1或第二周向方向R2转动时，所述第一传动部件通过单向转动件36带动拨弹轮18单向转动，其中，所述拨弹轮18单向转动的方向为第一周向方向R1或第二周向方向R2，即单向转动件38单向传动的传动方向为第一周向方向R1或第二周向方向R2，如此，在第一传动部件38的带动下，拨弹轮18可以实现单向转动。
具体地，拨弹盘20的轮毂26可以套设在单向轴承的外圈上，实现轮毂26 与外圈的固定连接，第一传动部件38连接单向轴承的内圈，实现第一传动部件38与内圈的固定连接。在第一传动部件38沿第一周向方向R1或第二周向方向R2转动时，会带动轴承的内圈转动，当第一传动部件18的转动方向与单向轴承的传动方向相同时，时，单向轴承的内圈会带动轴向轴承的外圈转动，进而带动拨弹轮18转动。
在一个例子中，参考轴线L为拨弹轮18的转动轴线，其中，拨弹轮18单向转动的方向与第一周向方向R1相同，即单向转动件36的传动方向与第一周向方向R1相同。也即是说，拨弹轮18沿第一周向方向R1转动。第一传动部件38沿第二周向方向R2转动，拨弹轮18静止不动，第一传动部件38可以回复到初始位置，所述初始位置为第一传动部件38沿第一周向方向R1转动之前所处的位置。
可以理解的是，在某些实施例中，拨弹轮18单向转动的方向可以与第二周向方向R2相同，即单向转动件36的传动方向与第二周向方向R2相同。也即是说，拨弹轮18沿第二周向方向R1方向转动。第一传动部件38沿第一周向方向R1转动，第一传动部件38可以回复到初始位置，拨弹轮18静止不动，所述初始位置为第一传动部件38沿第二周向方向R2转动之前所处的位置。
请参阅图4-图6，在某些实施方式中，动力部件14包括第一动力部件40和第二动力部件42，第一传动部件38在第一动力部件40的驱动下以参考轴线L为转动轴线沿第一周向方向R1转动，第一传动部件38在第二动力部件42的驱动下以参考轴线L为转动轴线沿背离第一周向方向R1的第二周向方向R2转动。
如此，第一传动部件38在两个动力部件的驱动下做周期性运动，使得第一传动部件38驱动拨弹盘20转动的方式更加容易实现。具体地，在第一动力部件40驱动第一传动部件38沿第一周向方向R1转动时，拨弹轮18在第一传动部件38的驱动下单向转动。当第一传动部件38沿第一周向方向R1转动到极限位置时，拨弹部22将射击弹推送到出弹口24，然后，第二动力部件42驱动第 一传动部件38沿第二周向方向R2转动，此时，由于单向转动件36只能单向转动的原由，拨弹轮18静止不动，第一传动部件38回复到初始位置。如此，第一传动部件38在往复运动的过程中可以连续地驱动拨弹轮18单向转动。
本实施方式中，第一动力部件40为驱动电机40，第二动力部件14为弹性部件14。也就是说，驱动电机40驱动第一传动部件38沿第一周向方向R1转动，弹性部件14驱动第一传动部件38沿第二周向方向R2转动。弹性部件14例如为拉伸弹簧、扭簧等元件。当然，在其他实施方式中，第一动力部件40为弹性部件，第二动力部件14为驱动电机。在某些实施例中，所述第一动力部件40可以为单独一个动力部件。
请参阅图7-8及图11，在某些实施方式中，拨弹盘20上设置限位件44，拨弹轮18上设置限位配合部46，限位件44与限位配合部46配合以限制拨弹轮18沿第二周向方向R2的转动。理想情况下，若拨弹轮18单向转动的方向与第一周向方向R1相同时，即若单向转动件36的传动方向与第一周向方向R1相同时，由于单向转动件36是单向传动部件，在第一传动部件38沿第二周向方向R2转动时，单向转动件36不会带动拨弹轮18沿第二周向方向R2转动，然而，在工程实际中，由于单向转动件36的设计和生产因素，单向转动件36可能不能完全实现单向传动，例如，单向轴承中由于内圈、外圈和滚动体之间存在摩擦，单向轴承不可能完全实现单向传动。如此，当限位件44与限位配合部46配合以限制拨弹轮18沿第二周向方向R2的转动，可以更加牢靠地保证拨弹轮18单向地转动，保证拨弹机构10更加可靠地将射击弹推送到出弹口24。
在一个例子中，限位件44为棘爪，限位配合部46为棘轮。如此，棘爪与棘轮配合不仅可以使得拨弹轮18单向转动更加牢靠，还可以限定拨弹轮18在每个周期内转过的角度，保证拨弹轮18在每个周期内将一个射击弹推进出弹口24内。例如，棘轮的轮齿28数量为8个，在每个周期内，棘轮转过的一个轮齿，拨弹轮18转过45度。
在某些实施方式中，传动组件16还包括第二传动部件48，其中，在驱动 电机40的驱动下，第二传动部件48带动第一传动部件38以参考轴线L为转动轴线沿第一周向方向R1和背离第一周向方向R1的第二周向方向R2中的一个方向转动；在弹性部件42的驱动下，第一传动部件38以参考轴线L为转动轴线沿第一周向方向R1和背离第一周向方向R1的第二周向方向R2中的另一个方向转动。如此，驱动电机40通过第二传动部件48可以带动第一传动部件38运动，从而驱动拨弹轮18转动。其中，所述第二传动部件48可以为任何直接地或者间接地接收到驱动电机40的驱动而进行运动，并带动第一传动部件38沿第一周向方向R1和背离第一周向方向R1的第二周向方向R2中的一个方向转动。例如，第二传动部件48带动第一传动部件38沿第一周向方向R1转动，当第一传动部件38沿第一周向方向R1转动时，连接到第一传动部件38上的弹性部件42会发生形变，当第一传动部件沿第一周向方向R1转动到极限位置时，弹性部件42在弹力的作用下带动第一传动部件38沿第二周向方向R2转动，第一传动部件回复到初始位置。可以理解的是，某些情况中，第二传动部件48带动第一传动部件38沿第二周向方向R2转动，当第一传动部件38沿第二周向方向R2转动时，连接到第一传动部件38上的弹性部件42会发生形变，当第一传动部件38沿第二周向方向R2转动到极限位置时，弹性部件42在弹力的作用下带动第一传动部件38沿第一周向方向R1转动，第一传动部件38回复到初始位置。
请参阅图5及图6，在某些实施方式中，第二传动部件48包括活塞组件50和设置在活塞组件50上的活塞传动部件52，其中，活塞组件50在驱动电机40的驱动下运行并带动活塞传动部件52运动，活塞传动部件52带动第一传动部件38以参考轴线L为转动轴线沿第一周向方向R1和背离第一周向方向R1的第二周向方向R2中的一个方向转动。活塞传动部件52带动第一传动部件38沿第一周向方向R1转动,第一周向方向R1例如为图6中的顺时针方向。
如此，拨弹轮18通过第一传动部件38与活塞组件50实现联动，使得射击装置12不仅可以避免出现重发、漏发等不良现象，还有利于射击装置12的结构紧凑，使得设计装置更加小型化。
具体地，请参图6，活塞组件50包括活塞缸54和伸入活塞缸54中的活塞56。活塞传动部件52大致呈杆状，活塞传动部件52自活塞缸54的一端沿活塞缸54的轴向向第一传动部件38延伸。活塞传动部件52的自由端设置有第一凸块58，第一传动部件38设置有第二凸块60，第一凸块58与第二凸块60配合以使活塞传动部件52带动第一传动部件38运动。
请再次参阅图4及图5，传动组件16包括还齿轮组件62，齿轮组件62与驱动电机40连接，活塞缸54上设置有与齿轮组件62啮合连接的齿条64，驱动电机40驱动齿轮组件62运动，从而带动活塞缸54运动。
请参阅图3、图8及图13，在某些实施方式中，拨弹盘20上设置有入弹口66，拨弹机构10还包括覆盖出弹口24的遮挡部68，其中，遮挡部68用于阻挡弹仓70中的射击弹直接进入出弹口24，即，阻挡弹仓70中经过出弹通道71进入拨弹机构10的射击弹不经过拨弹盘20直接进入出弹口24。如此，遮挡部68可以防止射击装置12每次射击出现将的多个射击弹射出的现象。
可以理解，入弹口66与拨弹盘20连通，弹仓70中的射击弹通过入弹口66可以落入拨弹盘20中。遮挡部68例如为板状，入弹口66位于遮挡部68一侧，入弹口66例如呈弧形或方形等形状。
请参阅图6及图8，在某些实施方式中，出弹口24设置有阻挡部72，用于限制推送到出弹口24的射击弹朝拨弹轮18单向转动的方向移动。
具体地，阻挡部72呈片状，阻挡部72自侧壁32向拨弹轮18延伸。阻挡部72位于出弹口24的一侧。在拨弹轮18推动射击弹以使射击弹位于出弹口24时，由于阻挡部72的阻挡，射击弹在阻挡部72和拨弹轮18的挤压下进入出弹口24内。阻挡部72与拨弹盘20可为一体结构，这样使得阻挡部72容易形成。
请参阅4及图6，在某些实施方式中，拨弹机构10包括三通管74，活塞缸54及出弹口24均与三通管74连通。如此，射击弹通过出弹口24落入三通管74后，活塞56在移动的过程中快速压缩空气，从而将射击弹从三通管74中射 出。
请参图4-图6，拨弹机构10的工作过程大致如下：
驱动电机40驱动齿轮组件62转动以带动活塞缸54和活塞56同时向后移动，在活塞缸54向后移动的同时，活塞传动部件52带动第一传动部件38运动从而带动拨弹轮18转动，第一复位弹簧76拉伸蓄能；在活塞缸54向后运动到极限位置的过程中，拨弹轮18同时将射击弹推送到出弹口24中以使射击弹进入三通管74内。在齿轮组件62继续转动的同时，活塞缸54上的齿条64与齿轮组件62脱离啮合，活塞缸54在第一复位弹簧76的带动下复位，活塞缸54在复位的过程中吸入周围的空气，活塞56在齿轮组件62的推动下继续向后移动并继续压缩第二复位弹簧78，在活塞56向后移动到极限位置时，活塞56与齿轮组件62脱离连接，此时，在第二复位弹簧78的作用下，活塞56快速地向前移动以压缩活塞缸54内的空气，压缩空气喷入三通管74内以将三通管74内的射击弹从枪管80射出，如此往复，从而可以实现将射击弹逐个、连续地发射。
