具体实施方式
以下详细说明本发明。在以下段落中，更为详细地限定了实施例的不同方面。如此限定的各方面可与任何其他的一个方面或多个方面组合，除非明确指出不可组合。尤其是，被认为是优选的或有利的任何特征可与其他一个或多个被认为是优选的或有利的特征。
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。
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90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。
如图1所示，在本实施例的技术方案中，传动组件包括转轴10、转动件20、第一传动结构30以及第二传动结构。其中，转动件20与转轴10配合并在转轴10的驱动下转动。第二传动结构40设置在转轴10上并与转轴10同步转动，第一传动结构30设置在转动件20上并与转动件20同步转动。第一传动结构30包括传动槽31，第二传动结构40包括突出结构41，突出结构41嵌入至传动槽31内并使第一传动结构30和第二传动结构40同步转动。转动件20被卡住时，突出结构41从传动槽31脱出并使第一传动结构30和第二传动结构40之间相对转动，以使转轴10继续转动。
应用本实施例的技术方案，转动件20带动转页扇的导风罩转动。当转页扇正常工作时，突出结构41嵌入至传动槽31内，进而使得转轴10能够带动传动扇转动。当转页扇被卡住时，突出结构41从传动槽31脱出，进而使得第一传动结构30和第二传动结构40之间相对转动，此时虽然转动件20被卡住不转动，但是转轴10依然能够转 动，进而保护电机不受损坏。因此本实施例的技术方案解决了现有技术中的转页扇的导风罩被卡住时电机容易损坏的问题。
如图1所示，在实施例一的技术方案中，转轴10上设置有卡销11，卡销11形成突出结构41。具体地，卡销11为棍状结构，棍状结构设置在转轴10上并且朝向转轴10的两侧延伸。优选地，棍状结构与转轴10垂直设置。其中，卡销11卡入至传动槽31内。在转动件20正常工作时，卡销11通过传动槽31带动第一传动结构30转动，进而使得转轴10能够带动转动件20转动。当转动件20被卡住时，转动件20和第一传动结构30均无法转动，此时卡销11受到转轴10的带动力继续转动，进而使卡销11从传动槽31脱出。当卡销11转动至一定角度时，卡销11在此卡入至传动槽31，并且在转轴10的带动下再次脱出传动槽31。因此，当转动件20被卡住时，卡销11的运动过程为“脱出传动槽31-卡入传动槽31-脱出传动槽31”往复运动，进而保证在转动件20被卡住的情况下转轴10能够继续转动。
优选地，传动槽31的槽壁呈倾斜状或者圆弧状，进而使得当转动件20被卡住时，卡销11能够从传动槽31脱出。进一步地，传动槽31的槽壁与水平面的夹角也不宜过小，因为上述的夹角越小，卡销11朝向传动槽31施加的径向力也就越小，从而使卡销11难以带动第一传动结构30转动。
优选地，卡销应选用弹性新能较好、抗变形能力较强的材料。由于当转动件20被卡住时，卡销11相对于传动槽31不停的跳动，因此卡销11需要选用强度较好的材料，进而防止卡销11发生疲劳断裂。
如图1所示，在实施例一的技术方案中，第一传动结构30还包括第一筒体部32，第一筒体部32的一端连接在转动件20上，传动槽31设置在第一筒体部32的第二端，转轴10穿设在第一筒体部32内以使卡销11与传动槽31配合。具体地，传动槽31设置在第一筒体部32的朝向转轴10的端面上。第一传动结构30与转动件20连接并且与转动件同步转动。转轴10穿设在第一筒体部32后，卡销11与第一筒体部32的朝向转轴10的端面抵接。转动件20相对转轴10转动一定角度后，卡销11卡入至传动槽31内。
如图1所示，在实施例一的技术方案中，传动槽31为多个，多个传动槽31沿第一筒体部32的周向均匀设置。具体地，多个传动槽31连续地、均匀地分布在第一筒体部32的朝向转轴10的端面。
如图1所示，在实施例一的技术方案中，转动件20为齿轮，第一筒体部32可拆卸地连接在齿轮上。齿轮具有连接孔21，第一筒体部32穿设在连接孔21内，传动组件还包括设置在连接孔21和第一筒体部32之间的第一定位结构50，第一定位结构50使第一筒体部32与齿轮同步转动。
如图1所示，在实施例一的技术方案中，第一定位结构50包括第一齿形部51和第二齿形部52。第一齿形部51设置在连接孔21的内壁上。第二齿形部52设置在第一筒体部32的第二端的外侧壁上，第一齿形部51和第二齿形部52互相啮合并使第一筒体部32与齿轮同步转动。当然，第一定位结构50也可以采用其他的定位结构，例如卡扣、销、键等。
优选地，本领域技术人员可以理解，实施例一的第一传动结构30和第二传动结构40的位置可以互相调换。也即第一传动结构30设置在转轴10上，第二传动结构40设置在转动件20上也可以实现转动件20防卡死的功能。
实施例一的传动结构对于齿轮的耐磨性要求较低，但是需要卡销11具有一定的强度的变形能力。
如图2所示，根据本申请的实施例二的传动结构和实施例一的区别在于，第一筒体部32与齿轮为一体结构。实施例二的技术方案和实施例一相比零部件少，便于安装并且传动稳定。但是实施例二的技术方案需要齿轮的材料具有一定的耐磨性。
如图3所示，根据本申请的实施例三的传动结构和实施例一与实施例二的区别在于，第二传动结构40包括第二筒体部42、悬臂结构43与传动凸起44。其中，第二筒体部42套设在转轴10上并与转轴10同步转动，悬臂结构43设置在第二筒体部42的外侧壁上。传动凸起44设置在悬臂结构43朝向转动件20的表面上，传动凸起44形成突出结构41。具体地，传动凸起44与传动槽31的配合过程和卡销11传动槽31的配合过程类似，在此不再赘述。当传动凸起44从传动槽31脱出时，悬臂结构43发生形变。
优选地，如图5和图6所示，悬臂结构43包括第一杆体、第二杆体和第三杆体。其中，第一杆体的第一端连接在第二筒体部42的外侧壁上，第二杆体的第一端连接在第二筒体部42的外侧壁上，第三杆体连接在第一杆体的第二端和第二杆体的第二端。传动凸起44设置在第三杆体的朝向转动件20的表面。上述的第一杆体、第二杆体和第三杆体形成了“匚”型结构。
如图3和图5所示，在实施例三的技术方案中，转轴10上设置有卡销11，第二筒体部42上设置有卡槽421，卡销11卡入至卡槽421内以使第二筒体部42与转轴10同步转动。
如图3所示，在实施例的技术方案中，第一传动结构30包括盘体部33，盘体部33的第一端连接在转动件20上，传动槽31设置在盘体部33的第二端。具体地，传动槽31设置在盘体部33的朝向转轴10的端面上。盘体部33和第二传动结构40抵接并使传动凸起44与传动槽31配合。
如图3所示，在实施例三的技术方案中，传动槽31为多个，多个传动槽31沿盘体部33的周向均匀分布在盘体部33的边沿处。具体地，多个传动槽31连续地，均匀地分布在盘体部33的边沿处。
如图3和图4所示，转动件20为齿轮，盘体部33可拆卸地连接在齿轮上。齿轮具有连接孔21，盘体部33的第一端设置有定位凸柱34，定位凸柱34穿设在连接孔21内，传动组件还包括设置在连接孔21和定位凸柱34之间的第二定位结构60，第二定位结构60使盘体部33与齿轮同步转动。
如图4所示，在实施例三的技术方案中，第二定位结构60包括定位槽61和定位凸筋62。其中，定位槽61设置在连接孔21的内侧壁上。定位凸筋62设置在定位凸柱34的外侧壁上，定位凸筋62嵌入至定位槽61内以使盘体部33与齿轮同步转动。当然，第二定位结构60也可以采用其他的定位结构，例如齿形配合，槽键配合等。
如图3所示，在实施例三的技术方案中，盘体部33上设置有定位通孔35，转轴10分别穿设过定位通孔35与连接孔21，进而使得第二定位结构60与盘体部33抵接。
实施例三的传动结构的特点在于，实施例三的技术方案对齿轮和卡销11的材料耐磨强度要求均较低。但是实施例三的零件数量相对于实施例一和实施例二的技术方案较多。
如图7至图10所示，根据本申请的传动结构的实施例四和实施例三的区别在于，盘体部33与齿轮为一体结构。实施例四的技术方案和实施例三相比零件数量较少，但是实施例四的技术方案需要齿轮的材料具有一定的耐磨性。
如图11所示，本实施例的转页扇，根据跟申请的转页扇的实施例包括导风罩100以及驱动导风罩100转动的传动组件200，传动组件200为上述的传动组件。
以上对本发明所提供的一种压缩机及换热系统进行了详细介绍。本文中应用了具 体的实施例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
