组合气缸活塞曲柄机构
技术领域 本发明涉及热能与动力领域， 尤其是一种组合气缸活塞曲柄机构。
背景技术 无论是传统活塞式发动机或传统气体压縮机， 在压縮过程中由于缸径相对 比较大， 很难使被压縮的气体中的热量得以有效散出， 所以压縮过程中的压縮 功功耗较大。缸径较大的机构也很难适用于缸内压力大幅度增加的压縮过程或 缸内压力大幅度增加的发动机的爆炸作功冲程。 然而， 如果单纯将气缸缸径縮 小， 为保证一定的排气量， 必须增加曲轴的长度， 曲轴长度的增加会带来很多 问题。 为此， 需要发明一种小缸径、 大行程， 而且曲轴长度适当的活塞曲柄机 构。
发明内容
为了解决上述问题， 本发明提出的技术方案如下：
一种组合气缸活塞曲柄机构， 包括气缸、 滑动塞结构体和曲柄销轴颈， 至 少两个所述气缸按轴线平行设置，在每个所述气缸内设置一个所述滑动塞结构 体， 每个所述滑动塞结构体分别与垂直承载结构体连接；

一部分所述滑动塞结构体与所述垂直承载结构体固连， 另一部分所述滑动 塞结构体与所述垂直承载结构体在所述气缸的轴线垂直方向上滑动连接；或一 部分所述滑动塞结构体与所述垂直承载结构体固连， 另一部分所述滑动塞结构 体与所述垂直承载结构体万向连接。 所述滑动塞结构体设为活塞连杆机构。
所述滑动塞结构体设为柱塞； 或所述滑动塞结构体设为活塞结构杆。 在设有所述连动式滑道的结构中，一部分所述气缸和另一部分所述气缸对 置设置， 所有所述滑动塞结构体与同一所述垂直承载结构体连接， 构成对置设 置组合气缸活塞曲柄机构。
在设有所述曲柄销轴颈孔的结构中， 所述滑动塞结构体的直径、所述滑动 塞结构体的组合体的宽度和所述垂直承载结构体的宽度均小于与同一个所述 曲柄销轴颈所对应的两个曲柄之间的距离。
设置定位滑道，所述垂直承载结构体或与所述垂直承载结构体固连的定位 结构体与所述定位滑道在与所述气缸平行的方向上滑动接触。
至少两个所述气缸按轴线共线设置构成所述气缸相互套装设置的结构，在 所述气缸相互套装设置的结构中，除一个所述滑动塞结构体之外的其他所述滑 动塞结构体设为环状滑动塞结构体。
与同一个所述垂直承载结构体连接的所述滑动塞结构体的工作相位设为 不同。
在将所述组合气缸活塞曲柄机构设为发动机用组合气缸活塞曲柄机构的 机构中， 全部或部分所述气缸共用一个燃烧室。
本发明所谓的滑动塞结构体是指与气缸滑动密封配合的塞状结构体，其功 能相当于活塞连杆机构， 它可以是活塞连杆机构， 可以是柱塞， 也可以是活塞 结构杆， 所谓活塞结构杆是指将活塞和连接杆固连的结构件； 所谓环状滑动塞 结构体是指设为环形的滑动塞结构体；所谓垂直承载结构体是指将两个或两个 以上的所述滑动塞结构体相互连接的结构件，其目的是使这些所述滑动塞结构 体在同一所述曲柄销轴颈直接作用下或经主连杆作用下共同往复运动，并在所 述滑动塞结构体和所述曲柄销轴颈之间承载和传递作用力；所谓主连杆是指将 所述垂直承载结构体和所述所述曲柄销轴颈相互连接的连杆；所谓连动式滑道 是指除在所设定的滑动方向上与所述滑块滑动接触外，在其他方向上与所述滑 块连动的滑道，即所述连动式滑道在所述气缸的轴线方向上与所述滑块连动进 行往复运动， 在所述气缸的轴线的垂直方向上与所述滑块滑动接触； 所谓滑动 塞结构体的组合体是指两个或多个所述滑动塞结构体所构成的整体； 所谓的 "所述滑动塞结构体的直径、所述滑动塞结构体的组合体的宽度和所述垂直承 载结构体的宽度均小于与同一个所述曲柄销轴颈所对应的两个所述曲柄之间 的距离"是为了实现使所述垂直承载结构体及与其相连的所述滑动塞结构体能 够进入与其相对应的两个曲柄之间， 从而降低整个机构的高度， 这实质上是用 滑块、滑道代替了与曲柄销轴颈连接的连杆； 所谓的 "与同一个所述垂直承载 结构体连接的所述滑动塞结构体的工作相位设为不同"是指两个或多个所述滑 动塞结构体共同趋近于上止点时， 其中一部分是处在压縮冲程， 而另一部分则 处在排气冲程， 同理两个或多个所述滑动塞结构体共同趋近于下止点时， 其中 一部分是处在吸气冲程， 而另一部分则处在作功冲程， 其目的是为了实现机构 的动平衡。
本发明中的气缸直径可以设为相同， 也可以设为不同。
本发明所公开的组合气缸活塞曲柄机构可以在对气体进行压縮的进程中 对被压縮气体进行高效冷却， 大幅度降低压縮功耗， 能够实现低增温压縮、 近 恒温压縮或恒温压縮，所谓的低增温压縮是指在压縮进程中有效地对被压縮气 体进行冷却使压縮后的气体压力高而温度处于相对较低的水平，所谓近恒温压 縮是指在压縮过程中被压縮气体的温度处于近乎不增加的状态。
本发明所谓的对置设置组合气缸活塞曲柄机构是指所述气缸对置设置、所 述滑动塞结构体对置设置，所述滑动塞结构体按其所在位置与所述垂直承载结 构体的上部连接或与所述垂直承载结构体的下部连接；此处的上部和下部是指 以滑道为界限的两侧。
所谓连接是指直接连接、 间接连接。
本发明所公开的组合气缸活塞曲柄机构可以用作压气机 （如空气压縮机 等）， 也可以用作活塞式发动机， 特别是可以用于缸内压力大幅度提高的压气 机和发动机。
本发明所公开的组合气缸活塞曲柄机构由于缸径可大幅度縮小，相当于缸 内被压縮气体的可以冷却的界面增大， 因此可以实现对缸内被压縮气体的高效 冷却。
本发明所公开的组合气缸活塞曲柄机构的气缸直径也可以与传统的气缸 直径相当， 在这种情况下可以实现气缸的矩阵式排列方式， 可以改变缸数较多 的发动机长而窄的传统模式， 实现发动机的宽度接近长度、 等于长度， 甚至大 于长度的气缸排列方式， 为优化曲轴长度， 气缸排列方式和优化发动机长宽比 提供一种新的选择。
本发明的有益效果如下：
1、本发明能够大幅度提高气缸内被压縮气体的冷却效率， 减少压縮功耗。
2、 由于缸径可以大幅度降低， 所以适合于缸内压力大幅度提高的机构。 附图说明
