Description

压缩机及具有其的车辆 技术领域
本发明涉及流体机械领域，具体而言，涉及一种压缩机及具有其的车辆。
背景技术
无油涡旋压缩机因其能够实现无油压缩以及效率高、体积小、质量轻、运行平稳等特点被广泛运用于新能源车制动领域。一般来说，涡旋压缩机由机壳、静涡旋盘、动涡旋盘、支架、曲轴、防自转机构和电机构成。动、静涡旋盘的型线均是螺旋形，动涡旋盘相对静涡旋盘偏心并相差180°安装，于是在动、静涡旋盘间形成了多个月牙形空间。在动涡旋盘以静涡旋盘的中心为旋转中心并以一定的旋转半径作无自转的回转平动时，外圈月牙形空间便会不断向中心移动，此时，空气被逐渐推向中心空间，其容积不断缩小而压力不断升高，直至与中心排气孔相通，高压空气被排出泵体，完成压缩过程。
防自转机构作为无油涡旋压缩机的核心部件，目前最常见的是小曲拐与滚动轴承组合结构，现有技术如下专利：
公开号为CN102971535B的专利公布了常用防自转结构，小曲拐是偏心结构，小曲拐偏心量与主轴偏心量相同。曲拐两端各有两个角接触滚动轴承，两组轴承分别安装驱动盘轴承室和机架轴承室中。因为需要给轴承注油润滑，在机壳上开设注油孔，在需要进行润滑油脂补给的时候，将固定涡旋盘拆除，通过注油孔向轴承室供油。公开号为CN100347449C的专利公布了一种涡旋流体机械，防转注油结构穿过位于防自转装置前面的支撑板形成。
在如上述专利公开的现有技术方案中，为防止轴承磨损，均需要对轴承与小曲拐运动配合处进行润滑，需要辅助很多注油结构及油通路。另外，也可能存在油脂消耗后出现异常磨损降低可靠性的问题。同时，现有无油涡旋压缩机的小曲拐防自转结构比较复杂，而且对小曲拐的加工精度要求很高，因此加工制造成本也较高。
发明内容
本发明旨在提供一种压缩机及具有其的车辆，以解决现有技术中压缩机防自转结构复杂并且仍需要油脂进行润滑的问题。
为了实现上述目的，根据本发明的一个方面，提供了一种压缩机，包括：支架，支架上设置有第一限位结构；动涡旋盘组件，可活动地设置在支架上，动涡旋盘组件上设置有第二限位结构；防自转结构，设置在支架和动涡旋盘组件之间，防自转结构上设置有第一定位结构和第二定位结构，第一定位结构可活动地设置在第一限位结构中，第二定位结构可活动地设置在第二限位结构中；第一悬浮结构，与第一定位结构和第一限位结构相配合，使第一定位结构和第一限位结构之间具有第一预定间隙；第二悬浮结构，与第二定位结构和第二限位 结构相配合，使第二定位结构和第二限位结构之间具有第二预定间隙。
进一步地，防自转结构包括圆环，第一定位结构为第一滑块并设置在圆环朝向支架的一侧，第一限位结构为第一滑槽，第一定位结构能够沿圆环的径向在第一限位结构中滑动；第二定位结构为第二滑块并设置在圆环朝向动涡旋盘组件的一侧，第二限位结构为第二滑槽，第二定位结构能够沿圆环的径向在第二限位结构中滑动。
进一步地，第一悬浮结构包括第一磁性件和第二磁性件，第一磁性件设置在第一定位结构中，第二磁性件设置在第一限位结构的相对的两个侧壁上，以使第一定位结构悬浮在第一限位结构中；第二悬浮结构包括第三磁性件和第四磁性件，第三磁性件设置在第二定位结构中，第四磁性件设置在第二限位结构的相对的两个侧壁上，以使第二定位结构悬浮在第二限位结构。
进一步地，第一磁性件和第二磁性件相对的表面上的磁性相同，第三磁性件和第四磁性件相对的表面上的磁性相同。
进一步地，第一磁性件和第二磁性件相对的表面之间具有第一预定间隙，第三磁性件和第四磁性件相对的表面之间具有第二预定间隙。
进一步地，第一定位结构设置有第一通孔，以露出第一磁性件与第二磁性件相对的表面，第二定位结构设置有第二通孔，以露出第三磁性件与第四磁性件相对的表面。
进一步地，第一定位结构沿圆环的第一直径布置，第二定位结构沿圆环的第二直径布置。
进一步地，第一直径和第二直径相垂直。
进一步地，动涡旋盘组件包括动涡旋盘和驱动盘，驱动盘设置在动涡旋盘和防自转结构之间，第二限位结构设置在驱动盘朝向防自转结构的一侧，动涡旋盘固定设置在驱动盘上，压缩机还包括曲轴，曲轴穿设在驱动盘上以驱动驱动盘移动。
进一步地，动涡旋盘朝向驱动盘的一侧设置有多个筋。
进一步地，压缩机还包括静涡旋盘，动涡旋盘和静涡旋盘之间形成压缩腔，静涡旋盘远离压缩腔的一侧设置有多个筋。
根据本发明的另一方面，提供了一种车辆，包括压缩机，压缩机为上述的压缩机。
应用本发明的技术方案，第一定位结构和第一限位结构、第二定位结构和第二限位结构限制了动涡旋盘组件的运动趋势，使动涡旋盘组件只能整体相对支架做公转运动，避免动涡旋盘组件在压缩机运转时发生自转的情况。第一悬浮结构和第二悬浮结构使防自转结构既不与支架相接触，又不与动涡旋盘组件相接触，减少了防自转结构与支架之间、防自转结构与动涡旋盘组件之间运动副产生的摩擦，使压缩机在防自转结构上不需要润滑油或润滑油脂，实现了真正意义上的无油压缩。并且本发明的第一悬浮结构、第二悬浮结构取代了现有压缩机中的轴承等结构，使本发明的压缩机结构简单，便于安装生产和维护。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。同时，应当明白，为了便于描述，附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备 可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为授权说明书的一部分。在这里示出和讨论的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它示例可以具有不同的值。应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
如图1和图2所示，本实施例的压缩机包括支架10，动涡旋盘组件、防自转结构40、第一悬浮结构50和第二悬浮结构60。其中，支架10上设置有第一限位结构11，动涡旋盘组件可活动地设置在支架10上，动涡旋盘组件上设置有第二限位结构21。防自转结构40设置在支架10和动涡旋盘组件之间，防自转结构40上设置有第一定位结构41和第二定位结构42，第一定位结构41可活动地设置在第一限位结构11中，第二定位结构42可活动地设置在第二限位结构21中。第一悬浮结构50与第一定位结构41和第一限位结构11相配合，使第一定位结构41和第一限位结构11之间具有第一预定间隙。与之相似地，第二悬浮结构60与第二定位结构42和第二限位结构21相配合，使第二定位结构42和第二限位结构21之间具有第二预定间隙。
应用本实施例的技术方案，第一定位结构41和第一限位结构11、第二定位结构42和第二限位结构21限制了动涡旋盘组件的运动趋势，使动涡旋盘组件只能整体相对支架10做公转运动，避免动涡旋盘组件在压缩机运转时发生自转的情况。第一悬浮结构50和第二悬浮结构60使防自转结构40既不与支架10相接触，又不与动涡旋盘组件相接触，减少了防自转结构40与支架10之间、防自转结构40与动涡旋盘组件之间运动副产生的摩擦，使压缩机在防自转结构40上不需要润滑油或润滑油脂，实现了真正意义上的无油压缩。并且本实施例的第一悬浮结构50、第二悬浮结构60取代了现有压缩机中的轴承等结构，使本实施例的压缩机结构简单，便于安装生产和维护。
如图1和图2所示，本实施例的动涡旋盘组件包括动涡旋盘30和驱动盘20，驱动盘20设置在动涡旋盘30和防自转结构40之间，第二限位结构21设置在驱动盘20朝向防自转结构40的一侧，动涡旋盘30固定设置在驱动盘20上。压缩机还包括曲轴70和静涡旋盘80，动涡旋盘30的涡盘31和静涡旋盘80的涡盘之间形成压缩腔90，曲轴70穿设在驱动盘20上以控制驱动盘20移动，进而控制动涡旋盘30相对静涡旋盘80转动，控制压缩腔90压缩空气。
本实施例的曲轴70包括主轴71和轴销72，轴销72偏心地设置在主轴71上，即轴销72的轴线与主轴71的轴线平行但不共线地设置。
如图2所示，本实施例的动涡旋盘30朝向驱动盘20的一侧设置有多个筋33，静涡旋盘80远离压缩腔90的一侧设置有多个筋。动涡旋盘30上的筋33和静涡旋盘80上的筋一方面增加了动涡旋盘30和静涡旋盘80与空气之间的接触面积，在压缩机运转时能够提升散热效果，另一方面提高了动涡旋盘30和静涡旋盘80的结构强度。
如图2至图4所示，本实施例的防自转结构40为十字滑环，除第一定位结构41和第二定位结构42外还包括圆环43。其中，第一定位结构41为设置在圆环43朝向支架10的一侧的第一滑块，第一限位结构11为第一滑槽，第一定位结构41能够沿圆环43的径向在第一限 位结构11中滑动。相似地，第二定位结构42为设置在圆环43朝向动涡旋盘组件的一侧的第二滑块，第二限位结构21为第二滑槽，第二定位结构42能够沿圆环43的径向在第二限位结构21中滑动。这样，当动涡旋盘组件在曲轴70的驱动下做公转运动时，通过第一定位结构41在第一限位结构11中的移动以及第二定位结构42在第二限位结构21中的移动，抵消动涡旋盘组件的自转趋势并实现公转运动。
如图2至图9所示，本实施例的第一悬浮结构50包括第一磁性件51和第二磁性件52，第一磁性件51设置在第一定位结构41中，第二磁性件52为对应地设置的两个，并设置在第一限位结构11相对的两个的侧壁上，以使第一定位结构41悬浮在第一限位结构11中。
具体地，如图10所示，第一磁性件51如图中的方式布置：左侧为N极、右侧为S级，两个第二磁性件52如图中的方式布置：左侧的第二磁性件52的N极与第一磁性件51的N极相对设置，右侧的第二磁性件52的S极与第一磁性件51的S极相对设置。这样，在“同极相斥”的作用下，第一定位结构41能够悬浮在两个第二磁性件52之间，并在第一磁性件51和第二磁性件52相对的表面之间留有第一预定间隙形成气隙，避免结构之间相互接触产生摩擦。
同理，第二悬浮结构60包括第三磁性件61和第四磁性件62，第三磁性件61设置在第二定位结构42中，第四磁性件62也是对应地两个，并设置在第二限位结构21相对的两个侧壁上，以使第二定位结构42悬浮在第二限位结构21。第三磁性件61和第四磁性件62相对的表面之间磁性相同，以在第三磁性件61和第四磁性件62相对的表面之间留有第二预定间隙，形成气隙。
上述结构简化了现有空气压缩机技术中防自转结构，并且避免了防自转结构需要油脂进行润滑的问题，使本实施例的压缩机在图1右侧实现压缩气体的部分实现了真正意义上的无油，间接解决了现有空气压缩机技术中加油脂或更换油脂工作复杂、难度高的问题。
具体地，如图4所示，本实施例的第一定位结构41上设置有第一通孔44，使第一磁性件51穿设在第一通孔44中，以露出第一磁性件51与第二磁性件52相对的表面，以降低第一磁性件51和第二磁性件52之间的磁阻。
同理，第二定位结构42上也设置有第二通孔45，以露出第三磁性件61与第四磁性件62相对的表面。
在其他实施例中，第一磁性件也可以为两个，两个第一磁性件设置在第一滑块的侧壁上以使第一滑块悬浮在第一滑槽中。第二磁性件同理，不再赘述。
如图3所示，在本实施例中，第一定位结构41沿圆环43的第一直径布置，第二定位结构42沿圆环43的第二直径布置第一直径和第二直径相垂直，以使动涡旋盘30能够相对静涡旋盘80做完整连续的圆周运动。
本申请还提供了一种车辆，根据本实施例的车辆(图中未示出)包括压缩机，压缩机包含上述全部或部分技术特征。
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：
第一定位结构和第一限位结构、第二定位结构和第二限位结构限制了动涡旋盘组件的运动趋势，使动涡旋盘组件只能整体相对支架做公转运动，避免动涡旋盘组件在压缩机运转时发生自转的情况。第一悬浮结构和第二悬浮结构使防自转结构既不与支架相接触，又不与动涡旋盘组件相接触，减少了防自转结构与支架之间、防自转结构与动涡旋盘组件之间运动副产生的摩擦，使压缩机在防自转结构上不需要润滑油或润滑油脂，实现了真正意义上的无油压缩。并且本实施例的第一悬浮结构、第二悬浮结构取代了现有压缩机中的轴承等结构，使本实施例的压缩机结构简单，便于安装生产和维护。
在本申请的描述中，需要理解的是，方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，在未作相反说明的情况下，这些方位词并不指示和暗示所指的装置或元件必须具有特定的方位或者以特定的方位构造和操作，因此不能理解为对本申请保护范围的限制；方位词“内、外”是指相对于各部件本身的轮廓的内外。
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转80度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本申请保护范围的限制。
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。
