结合图2至图11所示，根据本发明的实施例，提供了一种泵体组件。
具体地如图1所示，该泵体组件包括气缸组件10、法兰部20、转轴30和滑片40，法兰部20与气缸组件10相连接，法兰部20与气缸组件10围设成工作腔，法兰部20的位于工作腔内的表面上设置有让位部，转轴30穿设于法兰部20和气缸组件10内，转轴30上设置有滑片槽31，滑片40，滑片40可滑动地设置于滑片槽31内，滑片40的朝向法兰部20的端面设置有容纳部42，容纳部42内设置有限位结构50，限位结构50具有位于容纳部42内的避让位置，以及至少部分的限位结构50具有凸出于容纳部42的表面上的限位位置，其中，转轴30可带动滑片40转动，以使与滑片40对应的工作腔进行吸气作业和排气作业，当工作腔 进行吸气作业时，限位结构50与让位部相配合，以使限位结构50位于限位位置，滑片40的头部与工作腔的腔壁具有距离地设置。
在本实施例中，通过在滑片上设置限位结构，在法兰部的表面上设置让位部，当工作腔进行吸气作业时，限位结构与让位部配合，以使限位结构位于限位位置，滑片的头部与工作腔的腔壁具有距离地设置，这样设置避免了滑片的头部与工作腔的腔壁摩擦，进而降低了泵体组件的功耗。
如图9至图11所示，当工作腔进行排气作业时，限位结构50逐渐远离让位部，以使限位结构50逐渐移动至避让位置。通过限位结构与让位部配合，当限位结构位于让位部内时，此时工作腔处于吸气状态，滑片周向位移受到限位结构的限制，避免了滑片的头部与工作腔的腔壁摩擦，当限位结构移动至避让位置时，此时工作腔处于排气状态，滑片的周向位移不受限位结构的限制。
在本实施例中，容纳部42为限位槽，限位槽开设于滑片本体41的朝向法兰部20一侧的端面上，或，容纳部42为限位孔，限位孔为开设于滑片本体41的朝向法兰部20一侧的端面上，当然容纳部设置在滑片本体的两端，也可以一端为限位槽，一端为限位孔，通过限位槽或者限位孔将限位结构可活动地设置于其中。
如图4所示，限位结构50包括滚珠51和弹簧52，滚珠51可活动地设置于容纳部42内，弹簧52设置于容纳部42内，弹簧52的第一端与容纳部42的侧壁相抵接，弹簧52的第二端与滚珠51相抵接，当工作腔进行吸气作业时，弹簧52向滚珠51施加预紧力，以使部分的滚珠51位于容纳部42外。利用弹簧的弹力和压缩能力，将滚珠由容纳部弹出或压入容纳部内，这样设置使得滑片本体通过滚珠与让位部相接触配合，滑片的头部与工作腔的腔壁具有距离地设置，这样设置避免了滑片的头部与工作腔的腔壁摩擦。
如图2和图4所示，法兰部20包括上法兰和下法兰，让位部开设于上法兰和下法兰的至少一个上。这样设置使得滑片的周向位移受限时，滑片所受约束力均匀。
如图6至图7所示，上法兰或下法兰包括法兰本体，法兰本体上开设有供转轴30穿过的轴孔22，让位部包括让位凹部21，让位凹部21开设轴孔22的孔壁处，当工作腔进行吸气作业时，弹簧52向滚珠51施加预紧力，以使部分的滚珠51位于让位凹部21，部分的滚珠51的表面与让位凹部21的侧壁相抵接，以使滑片40的头部与工作腔的腔壁之间具有距离地设置。通过让位凹部的侧壁对滚珠的表面进行转轴的周向方向约束，进而使滑片40的头部与工作腔的腔壁之间具有距离地设置。
如图5至图7所示，让位凹部21包括限位段211，限位段211开设于轴孔22的边沿处，限位段211的深度方向沿轴孔22的轴线方向延伸设置，限位段211的靠近轴孔22的一侧的底面与轴孔22的孔边沿相平齐，限位段211具有限位面，限位面远离轴孔22的孔边沿设置并与底面具有夹角地设置，当滚珠51位于限位位置时，部分的滚珠51与限位面相抵接。让位部还包括：第一过渡段212，第一过渡段212的第一端与限位段211的第一端相连接，第一过渡段212的第二端与法兰本体的朝向工作腔一侧的表面相连接，第一过渡段212的第一端至第 一过渡段212的第二端的高度逐渐增加，以使滚珠51逐渐移动至容纳部42内，直至滚珠51位于避让位置。让位部还包括：第二过渡段213，第二过渡段213的第一端与限位段211的第二端相连接，第二过渡段213的第二端与法兰本体的朝向工作腔的一侧的表面相连接，第二过渡段213的第一端至第二过渡段213的第二端的高度逐渐增加平缓延伸设置，以使滚珠51逐渐从容纳部42内滑出，直至滚珠51位于限位位置。让位凹部21起始段即第一过渡段212和末段即第二过渡段213均是斜坡形式，利于滚珠的进入和离开让位凹部21。当滑片组件处于吸气段时，滚珠在弹簧的弹力弹出进入让位凹部21，起到限位作用，当吸气完成后，滑片本体离开限位区域，滚珠在法兰端面压力下挤压弹簧，滚珠压回滚珠孔中，不对滑片产生限位。
在本实施例中，滑片槽31为多个，滑片40为多个，多个滑片40与多个滑片槽31一一对应地设置，相邻的两个滑片之间形成工作腔。在本实施例中，通过三个滑片将工作腔分割为4部分，通过电机驱动主轴旋转，带动滑片运动，从而实现工作腔的吸气、压缩和排气过程。
根据本发明的另一个方面，提供了一种滑片结构，该滑片结构，包括滑片本体41和限位结构50，滑片本体41的至少一个断面上设置有容纳部42，限位结构50可活动地设置于容纳部42内，限位结构50具有位于滑片本体41内的避让位置，以及限位结构50具有凸出于滑片本体41的表面上的限位位置。通过在滑片上设置限位结构，在法兰部的表面上设置让位部，当泵体组件的工作腔进行吸气作业时，限位结构与让位部配合，以使限位结构位于限位位置，滑片的头部与工作腔的腔壁具有距离地设置，这样设置避免了滑片的头部与工作腔的腔壁摩擦，进而降低了泵体组件的功耗。
在本实施例中，容纳部42为限位槽，限位槽开设于滑片本体41的朝向法兰部20一侧的端面上，或，容纳部42为限位孔，限位孔为开设于滑片本体41的朝向法兰部20一侧的端面上。当然容纳部设置在滑片本体的两端，也可以一端为限位槽，一端为限位孔，通过限位槽或者限位孔将限位结构可活动地设置于其中。
进一步地，限位结构50包括滚珠51、弹簧52，滚珠51可活动地设置于容纳部42内，弹簧52设置于容纳部42内，弹簧52的第一端与容纳部42的侧壁相抵接，弹簧52的第二端与滚珠51相抵接，弹簧52向滚珠51施加预紧力，以使部分的滚珠51位于容纳部42外。通过弹簧对滚珠施加预紧力，可以方便地将滚珠隐藏至容纳部内或者将滚珠由容纳部内弹至容纳部外。
在本实施例中，滑片本体41开设有与容纳部42相连通的排气孔43。因滚珠工作过程中有体积的变化，因此在滑片上设置有排气孔，以防滚珠挤压气或压油而导致不易于由容纳部进出。
其中，容纳部42为两个，两个容纳部42分别设置于滑片本体41的相对的两个端面上，两个容纳部42相连通地设置，排气孔43设置于滑片本体41尾部的中部，排气孔43均与两 个容纳部42相连通。通过将排气孔与容纳部相连通，使得滚珠可以方便地由容纳部进出。该弹簧滚珠结构不影响非吸气段背压槽的设计，设计更灵活方便。
根据本发明的另一个方面，提供了一种压缩机，包括泵体组件，泵体组件为上述实施例的泵体组件。
根据本发明的另一个方面，提供了一种空调器，包括泵体组件，泵体组件为上述实施例的的泵体组件。
如图1所示，现有技术中，气缸组件10’中的旋转滑片40’因要保证旋转工作过程中滑片的跟随性，其尾部的滑片槽31’必须提供一定背压，该背压通过滑片头部作用到气缸内壁上传化为摩擦阻力，从而产生摩擦功耗。
根据旋转滑片式压缩机的结构特点，工作过程分为吸气段、压缩段和排气段三个阶段。在吸气段，滑片头部为吸气压力，尾部为背压力，此时滑片头部对气缸内壁作用力最大，而吸气段滑片随着滑片槽是伸出运动，滑片头部的旋转半径是增大过程，即滑片头部线速度越来越大，根据W＝FV，滑片头部功耗在吸气阶段不仅较大，且是个增大的过程，因此吸气段的滑片头部功耗在整个运行周期中占有较大的比重。通过滑片尾部端面设置弹簧滚珠限位结构，该弹簧滚珠限位结构与上下法兰让位凹部21相配合，保证吸气段滑片头部与气缸内壁大间隙不接触，对降低该处的功耗有显著的作用。
另外，吸气段滑片两侧均是吸气压力，限位结构保证了滑片与气缸内壁大间隙连通，即无需严格控制吸气段滑片头部与气缸内壁间隙，这降低了摩擦功耗的同时，解决了吸气腔吸气量不足的问题，对提高压缩机冷量有利。
如图8至图11所示，压缩机工作过程分为吸气、压缩、排气三个阶段，转轴旋转过程中，带动滑片运动，为减小滑片头部与气缸内壁摩擦功耗。以滑片40为例说明，当滑片40处于图8位置时，此时弹簧滚珠限位结构刚开始作用于让位凹部21，滑片40处于限位状态；当滑片40处于图9位置时，此时滑片40处于限位状态，滑片40不伸出，滑片40的左右腔连通状态，共用吸气通道，利于吸气；当滑片40处于图10位置时，此时滑片40处于限位状态，滑片40逐渐伸出，滑片40的左右腔还是连通状态，共用吸气通道，利于吸气；当滑片40处于图11位置时，此时滑片40处于刚好处于不限位状态，滑片40完全伸出，吸气完成。整个吸气过程滑片40与气缸内壁没有接触，且留有很大间隙，这样即消除了吸气段的摩擦功耗，又解决了吸气不足的问题，对改善压缩机性能效果明显。
除上述以外，还需要说明的是在本说明书中所谈到的“一个实施例”、“另一个实施例”、“实施例”等，指的是结合该实施例描述的具体特征、结构或者特点包括在本申请概括性描述的至少一个实施例中。在说明书中多个地方出现同种表述不是一定指的是同一个实施例。进一步来说，结合任一实施例描述一个具体特征、结构或者特点时，所要主张的是结合其他实施例来实现这种特征、结构或者特点也落在本发明的范围内。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。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，均应包含在本发明的保护范围之内。
