具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，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，决不作为对本发明及其应用或使用的任何限制。基于本发明中的实施例，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，都属于本发明保护的范围。
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发明的范围。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。
在本发明的描述中，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发明和简化描述，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发明保护范围的限制；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发明保护范围的限制。
如图1和图2所示，本发明实施例提供了一种导风板组件，该导风板组件包括导风板10和调节定位部20。其中，导风板10可转动地设置在通风框架30上，通过转动导风板10的设置角度可以调节进出风方向。其中，在本实施例中，该通风框架30上设置有出风口和进风口，导风板10对应设置在通风框架的出风口处，以调节出风方向。调节定位部20设置在导风板10和通风框架30之间，通过调节定位部20能够固定导风板10在通风框架30上的位置。其中，调节定位部20可以为紧固件、支撑结构等其它结构，只要不影响导风板10的转动并能对导风板10进行固定即可。其中，导风板组件可以设置在冷风扇、净化器等其它具有进出风口的电器上。
应用本实施例提供的导风板组件，在导风板10和通风框架30之间设置调节定位部20，可以通过调节定位部20固定导风板10在通风框架30上的位置。使得用户在调节导风板10的导风角度后，通过调节定位部20即可固定导风板10，方便用户使用。并且，该调节定位部20相比现有技术中通过轴孔配合的方式，紧固效果更好，可靠性更高，使用寿命更长。本发明提供的导风板组件结构简单，设计成本低，便于生产和制造。
具体地，为了在实现对导风板10固定的同时，不影响用户对导风板10进行转动。如图2所示，在本实施例中，该调节定位部20具体包括弹性固定件21和限位件22。其中，弹性固定件21具有弹性端。弹性端与限位件22抵接变形以使弹性端和限位件22之间具有预紧力，通过弹性固定件21与限位件22配合以固定导风板10在通风框架30上的位置。
通过弹性固定件21和限位件22配合，能够对导风板10提供支撑，并能够通过弹性固定件21的弹性端提供的弹性力对导风板10进行预紧，使导风板10的连接轴与通风框架30的孔壁紧贴，增大了导风板10和通风框架30的摩擦力，提高了紧固效果。
在上述结构中，弹性固定件21的弹性端提供的可以是压缩力，也可以拉伸力。在本实施例中，弹性端提供的是压缩力，即弹性端在与限位件22抵接时处于压缩状态。
并且，弹性固定件21可以设置在通风框架30上，将限位件22设置在导风板10上；也可将弹性固定件21设置在导风板10上，将限位件22对应设置在通风框架30上。在本实施例中，将弹性固定件21设置在通风框架30上，限位件22设置在导风板10上。如此可以方便用户调节导风板10的位置，提高装置结构的稳定性。
具体的，如图5和图6所示，该弹性固定件21包括基板211和弹片212。其中，基板211固定设置在通风框架30上，弹片212设置在基板211上，弹片212的一端与基板211连接，弹片212的另一端与限位件22抵接，通过弹片212对导风板10提供弹性力，以对导风板10进行固定。其中，基板211与弹片212可以设置为一体结构，也可将弹片212通过紧固件或其它连接方式连接在基板211上。将弹性固定件21设置为基板211和弹片212，可以在满足对导风板10进行固定的同时简化装置结构，便于设计和安装。
在本实施例中，在基板211上设置有避让孔，弹片212的一端设置在该避让孔内，弹片212的另一端从避让孔内伸出，弹片212与基板211呈夹角设置。通过设置避让孔可以防止弹片212在与限位件22抵接压缩时弹片212与基板211发生干涉。为了便于生产和加工，将弹片212与基板211设置为一体结构。
其中，基板211可通过紧固件设置在通风框架30上，也可通过卡接结构固定设置在通风框架30上。在本实施例中，在基板211上设置卡扣211a，基板211通过卡扣211a与通风框架30卡接以实现基板211与通风框架30的固定。其中，卡扣211a的数量和设置位置不做限定，可根据需要具体设置。在本实施例中，在基板211的上侧、左侧以及右侧均设置有卡扣211a，通风框架30上可对应设置卡接槽或其它卡接结构进行配合，以使基板211稳固设置在通风框架30上。此外，为了提高基板211与通风框架30的稳定性，还可在基板211上设置安装孔，以在卡扣211a失效或连接不稳定时，通过在安装孔内设置紧固件来对基板211和通风框架30进行连接。
具体的，如图3和图4所示，基板211通过卡扣211a设置在通风框架30上，在图3中，左侧为将基板211设置在通风框架30上，右侧与基板211的卡扣211a配合的连接孔，基板211在与通风框架30连接时，将基板211上的卡扣211a对应设置在连接孔内进行卡接即可。拆卸时，对卡扣211a施加力使其变形缩小并从连接孔内退出 即可。本实施例提供的基板211结构简单，方便工作人员对基板211进行安装和拆卸。
其中，弹性固定件21的弹性端与限位件22进行抵接时，为了提高抵接可靠性，可在限位件22上设置与弹性端配合的限位结构。该限位结构可以为限位孔、限位槽等其它限位结构。如图2所示，在本实施例中，在限位件22上设置限位凹槽221，通过限位凹槽221限定弹性端的位置。通过该结构，能够将弹性端限定在限位凹槽221内，以使导风板10在固定状态下弹性端与限位件22能够时刻抵接，提高连接的可靠性。
具体的，在限位件22上沿导风板10的转动方向可设置多个限位凹槽221，一个限位凹槽221对应一个导风角度，如此便于用户将导风板10调节到所需角度上。并且，在本实施例中，相邻两个限位凹槽221之间为圆滑过渡，多个限位凹槽221形成波浪形，如此可便于用户将弹性端调节至各个限位凹槽221内，减少二者之间的摩擦，提高装置结构的使用寿命，提高装置结构的可操作性。
其中，调节定位部20可以设置一个，也可设置多个。在本实施例中，将调节定位部20设置为多个，多个调节定位部20沿导风板10的长度方向间隔设置。通过设置多个调节定位部20，能够避免导风板10在使用时发生晃动，提高了导风板10的稳定性。
如图3和图4所示，该导风板组件上设置两个调节定位部20，两个调节定位部20以导风板10的中心线对称设置。
如图1和图2所示，在本实施例中，导风板10设置有多个，多个导风板10并排设置。该导风板组件还包括连杆40，连杆40与每个导风板10连接，以使多个导风板10同步转动。通过设置连杆40，可在用户调节任意一个导风板10时，其它导风板10与该导风板10同步转动调节，为用户提供便利。
其中，限位件22可独立设置在导风板10上，也可将限位件22设置在连杆40上。为了简化装置结构，在本实施例中，将限位件22设置在连杆40上。通过调节定位部20与连杆40配合，能够同时固定多个导风板10的位置，无需一个调节定位部20对应固定一个导风板10。上述设计方式能够简化装置结构，降低生产成本。
具体的，如图2和图7所示，连杆40上还设置有安装槽41，安装槽41设置在连杆40的与限位件22相对的一侧，导风板10上设置有连接轴11，连接轴11可枢转地设置在安装槽41内。安装时，只需要将导风板10的连接轴对应设置在安装槽41内即可，连杆40上的限位件22通过与通风框架30上的弹性固定件21配合对导风板10进行固定。在本实施例中，连杆40与限位件22设置为一体结构。安装槽41的开口尺寸 小于槽内尺寸，具体的，将安装槽41的开口尺寸设计为小于连接轴11的直径，安装时将导风板10上的连接轴11挤压至安装槽41的槽内，如此可将连接轴11限定在安装槽41内，并能使连接轴11在安装槽41内枢转。
如图2所示，每个导风板10上具有两个间隔设置的连接轴11，导风板组件包括两个连杆40，每个导风板10设置在两个连杆40上，即每个导风板10上的两个连接轴11对应设置在两个连杆40的安装槽41内。
通过本发明提供的导风板组件，将弹性固定件21的弹片212与连杆40上的限位件22相互配合限位，可以固定导风板10在通风框架30上的位置。当用户调节好导风方向后，由于弹片212的弹力作用，导风板10和连杆40可以保持此调节位置，固定不变。弹片212具有弹力，当用户对导风板10施力时，导风板10能调节并进行上下转动，松手后导风板10可以固定到某一限位凹槽221内。本发明提供的导风板组件，结构简单、稳定，可靠性高。
如图8所示，本发明又一实施例提供了一种冷风扇，冷风扇包括导风板组件。其中，该导风板组件为上述实施例提供的导风板组件。
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。
