技术领域
本申请涉及空调技术领域，例如涉及一种空调室内机及空调器。
背景技术
导风板作为空调器进行出风导向的主要部件，为了进行更广范围的送风，需要导风板能够旋转较大角度。
现有技术中为了实现导风板的大角度旋转，多数采用先将导风板推出机身足够距离，再驱动导风板旋转的方案，以使导风板能够实现大角度转动，并避免导风板在旋转过程中与壳体发生干涉。
但是该种设置需要两套驱动设备，分别用于推出导风板和驱动导风板旋转，占用了空调室内机的内部空间，且运动机构数量多增加了空调器的成本，增高了设备的故障的概率，导风板运动的可靠性低。
因此需要提供一种能够通过一套驱动结构即可实现导风板推出并旋转的空调室内机。

本申请采用第一连杆作为推出导风板本体的主要结构，第二连杆作为推动导风板旋转的主要结构，第一连杆与第二连杆配合实现导风板的大角度旋转，其中，驱动元件上设置有凸柱，导风板驱动组件通过凸柱驱动第一连杆推出导风板本体，通过凸缘推动通槽驱动第二连杆转动进而推动导风板本体旋转。当凸柱位于第一导轨的第一区域或第二区域时，导风板被第一连杆推出到机身外侧，当凸缘位于通槽的第三区域时，导风板处于向下开口状态，当凸缘位于通槽的第四区域时，导风板本体处于向上开口状态。
由于本申请的驱动元件可以驱动第一连杆和第二连杆，本申请的导风板驱动组件采用一组驱动结构即可实现导风板的推出和旋转动作，解决驱动结构数量多导致空调器成本升高、导风板运动可靠性低的问题。

本公开实施例的凸缘421为设置在驱动元件40的边缘位置且为凸出结构，用于推动通槽31使第二连杆30在第一连杆20上运动。
需要说明的是，在不冲突的情况下，本公开实施例中的实施例及实施例中的特征可以相互组合。
结合图1-10所示，本公开实施例提供一种空调室内机，包括导风板本体50、驱动结构、第一连杆20和第二连杆30。
导风板本体50设置有安装座51。
驱动结构包括驱动元件40，驱动元件40上设置有凸缘421和凸柱422。
第一连杆20，端部与安装座51连接，第一连杆20设置有第一导轨22，第一导轨22与凸柱422配合，驱动元件40通过凸柱422驱动第一连杆20移动。
第二连杆30，端部与安装座51连接，第二连杆30安装在第一连杆20上，第二连杆30设置有通槽31，凸缘421与通槽31位置配合，驱动元件40通过凸缘421推动通槽31驱动第二连杆30在第一连杆20上移动。
当凸柱422位于第一导轨22的第一区域221或第二区域222时，导风板本体50位于空调室内机的机身的外侧；当凸缘421位于通槽31的第三区域311时，导风板本体50处于向下开口状态；当凸缘421位于通槽31的第四区域312时，导风板本体50处于向上开口状态。
可以理解为，本申请采用第一连杆20作为推出导风板本体50的主要结构，第二连杆30作为推动导风板旋转的主要结构，第一连杆20与第二连杆30配合实现导风板的大角度旋转，其中，驱动元件40上设置有凸柱422和凸缘421，凸柱422与第一导轨22滑动配合或滚动配合，导风板驱动组件通过凸柱422驱动第一连杆20推出导风板本体50，由于第二连杆30与导风板本体50连接，第二连杆30也随着第一连杆20进行伸缩，第二连杆30设置有环形结构，中间设置有通槽31，导风板驱动组件通过驱动元件40的凸缘421推动通槽31侧壁驱动第二连杆30在第一连杆20发生转动，进而推动导风板本体50旋转。当凸柱422位于第一导轨22的第一区域221或第二区域222时，导风板被第一连杆20推出到机身外侧，凸柱422对第一导轨22产生一个分力驱动第一连杆20向外伸出并将导风板本体50推出机身，导风板本体50由于与第二连杆30铰接，因此导风板本体50移动的同时将带动第二连杆30同步向外伸出，在此过程中，第一连杆20与第二连杆30相对静止，当凸柱422到达第一导轨22的第一端或第二端 时，凸缘421开始与通槽31的下边缘接触。在此过程中，凸缘421逐渐抵住矩形通槽31的下边缘，推动第二连杆30移动，由于第一连杆20只能做伸缩运动，第二连杆30与第一连杆20只在导向柱33与第二导轨23有配合关系，因此第二连杆30将在凸缘421的推力下发生偏移，并推动导风板本体50转动。若此时凸缘421位于通槽31的第三区域311，导风板处于向下开口状态；若此时凸缘421位于通槽31的第四区域312，导风板本体50处于向上开口状态。
采用本公开实施例提供的空调室内机，可通过一组驱动结构即可实现导风板的推出和旋转动作，解决驱动结构数量多导致空调器成本升高、导风板运动可靠性低的问题。
作为一种示例，如图9所示，安装座51上设置有第一铰接点511和第二铰接点512，第一铰接点511与第一连杆20的端部连接，第二铰接点512与第二连杆30的端部连接。
可选地，通槽31与第一导轨22位置配合，凸柱422穿过通槽31与第一导轨22滑动连接。这样，能够便于驱动元件40驱动第一连杆20和第二连杆30，并避免第一连杆20和第二连杆30的运动发生干涉，第二连杆30可通过导向柱33在第二导轨23上转动或移动。
可选地，通槽31为矩形通槽31。这样，能够便对第二连杆30的运动轨迹进行控制。
结合图7所示，可选地，驱动元件40包括：连轴座41；连接杆42，一端与连轴座41连接，另一端设置凸缘421，凸柱422设置在连接杆42朝向第一连杆20的一面。
可以理解的是，本公开实施例的驱动元件40为钥匙状结构，连轴座41中部设置有孔，用于与电机的驱动轴连接，连接杆42与连轴座41的侧边连接，驱动元件40旋转时，连接杆42及凸柱422同步旋转，凸缘421位于连接杆42的端部，位于第二连杆30的通槽31内，能够通过与通槽31的内侧壁接触触发第二连杆30运动，凸柱422位于连接杆42朝向第一连杆20的一面，能够便于凸柱422与第一导轨22配合，以使凸柱422驱动第一连杆20运动。
可选地，凸柱422与驱动元件40的旋转轴之间的距离大于或等于设定距离。
可以理解的是，凸柱422作为驱动导风板本体50离开机身的主要部件之一，凸柱422与旋转轴之间的距离决定了凸柱422在第一导轨22上的移动距离，也将影响第一连杆20在底架10上的移动距离以及导风板本体50被推离机身的距离。因此凸柱422与驱动元件40旋转轴之间的距离应大于或等于设定距离，以使第一连杆20能够将导风板本体50推出足够长度。其中，设定距离为能够使第一连杆20将导风板本体50推出 且不会影响导风板本体50转动的长度。其中，该旋转轴可以为虚拟轴，也可以为驱动驱动元件40旋转的电机的驱动轴。
结合图2所示，可选地，第三区域311位于通槽31的底部侧壁的第一部分，第四区域312位于通槽31的底部侧壁的第二部分。
可以理解的是，第三区域311和第四区域312分别位于通槽31底部侧壁的两侧。第三区域311用于与凸缘421配合使导风板本体50向下开口，第四区域312用于与凸缘421配合使导风板本体50向上开口。
可选地，当凸缘421位于第三区域311时，凸缘421推动通槽31的底部侧壁，使第二连杆30在第一连杆20沿第一轨迹移动。
可以理解的是，结合图2所示，若驱动元件40以逆时针方向转动时，当凸缘421位于第三区域311，第二连杆30推动导风板以第一轨迹移动，使第二连杆30朝着空调室内机的侧下方运动，使第二连杆30推动导风板本体50向下开口。
可选地，当凸缘421位于第四区域312时，凸缘421推动通槽31的底部侧壁，使第二连杆30在第一连杆20沿第二轨迹移动。
可以理解的是，结合图2所示，若驱动元件40以顺时针方向转动时，当凸缘421位于第四区域312，第二连杆30推动导风板以第二轨迹移动，使第二连杆30朝着空调室内机的侧上方运动，使第二连杆30推动导风板本体50向上开口。
结合如图3、4、5、6所示，可选地，第一连杆20上设置有第二导轨23；第二连杆30上设置有导向柱33，导向柱33与第二导轨23滑动配合；第二连杆30可以导向柱33为轴在第一连杆20上转动。
可以理解的是，第二连杆30通过导向柱33与第一连杆20进行滑动配合，使第二连杆30可沿着第二导轨23进行移动。且，导向柱33为圆柱形结构，第二连杆30可以以导向柱33为轴在第一连杆20上转动，导向柱33设置在杆体32朝向第一连杆20的一面。第二连杆30可在第二导轨23上以导向柱33为轴相对于第一连杆20进行旋转。当第二连杆30进行转动时，第二连杆30将推动导风板本体50以第一连杆20与导风板本体50的连接的第一铰接点511为轴进行旋转。其中，第二连杆30的旋转动作和沿第二导轨23进行移动的动作可同时发生，也可只沿第二导轨23进行移动。
可选地，第一导轨22的延伸方向与第一导向结构11和第二导向结构21配合指引的方向呈角度设置。
可以理解的是，当驱动元件40旋转时，凸柱422将沿着第一导轨22进行移动， 由于驱动元件40呈圆周形运动，因此凸柱422给第一导轨22的力可分解为两部分，一部分力推动凸柱422在第一导轨22移动，另一部分力推动第一连杆20沿第一导向结构11和第二导向结构21配合指引的方向移动，使第一连杆20将导风板本体50从机身中推出。
作为优选，第一导轨22的延伸方向与第一导向结构11和第二导向结构21配合指引的方向垂直设置。第一导轨22与第二导轨23垂直设置。这样能够避免第一连杆20与第二连杆30的运动相互干扰或者抵消。
可选地，第二导轨23的长度大于或等于第二连杆30上导向柱33的移动距离，以满足摆风角度的要求。
可选地，第一连杆20包括：限位结构，设置在第二导轨23的侧部，用于对第二连杆30的旋转限位。
可以理解的是，第一连杆20的两侧分别设置有第一限位结构24和第二限位结构25，用于对第二连杆30的旋转范围进行限制。
作为一种示例，第一限位结构24的第一侧面用于与导风板本体50抵接，限制导风板本体50的向上开口角度，第一限位结构24的第二侧面用于限位第二连杆30第一方向的旋转角度，第二限位结构25的第一倾斜面用于与导风板本体50抵接，限制导风板本体50的向下开口角度，第二限位结构25的第二倾斜面用于限位第二连杆30第二方向的旋转角度。第一侧面所在平面与第二导轨23之间的夹角大于第一倾斜面所在平面与第二导轨23之间的夹角，第二侧面所在平面与第二导轨23之间的夹角小于或等于第二倾斜面所在平面与第二导轨23之间的夹角，以使导风板本体50的向上开口角度大于向下开口角度。
同时第一限位结构24和第二限位结构25也可给电控设计提供输入参数，当导风板转动到干涉位置时，电机在此处收到过步堵转，能够压紧导风板使其不会产生松动，此时电机停止运动，在此过程中，电机将根据转动角度记录电机运动步数，当导风板本体50达到最大角度时，电机停止驱动，且不会影响设备的正常使用。需要说明的是，导风板本体50也可不与第一限位结构24或第二限位结构25接触，直接通过电机控制导风板本体50运动的启停。第一限位结构24和第二限位结构25的主要用来控制第二连杆30在第一连杆20上的转动范围。
结合图8所示，可选地，空调室内机还包括：底架10，设置有第一导向结构11；第一连杆20上设置有与第一导向结构11配合的第二导向结构21；第一导向结构11与 第二导向结构21用于为第一连杆20的移动导向。
可以理解的是，第一连杆20作为将导风板本体50推出机身的主要部件，为了确保导风板的移动轨迹不发生偏移，需要设置导向结构进行导向，本公开实施例将第一导向结构11设置在底架10上，能够便于导风板驱动组件的整体安装，使用时无需对空调器进行大幅改动，减少了空调的生产成本，且节省了空调室内机的占用空间。
作为一种示例，第一导向结构11为平行设置的双导轨，第二导向结构21为分别设置于双导轨中各导轨的滑块，以使第一连杆20具有足够的运动稳定性。此外，也可将第二导向结构21设置为平行设置的双导轨，第一导向结构11为分别设置于双导轨中各导轨的滑块。
下面以图1至10为例，对本公开实施例的工作原理进行讲解。
底架10上设置有第一导向结构11，第一连杆20朝向底架10的面上设置有与第一导向结构11配合的第二导向结构21，第一连杆20远离底架10的一面设置有第一导轨22、第二导轨23、第一限位结构24和第二限位结构25。其中，第一导轨22与第一导向结构11的延展方向垂直，第二导轨23的延展方向与第一导向结构11和第二导向结构21配合指引的方向相同，第一限位结构24位于第二导轨23的一侧，第二限位结构25位于第二导轨23的另一侧。其中，第一导轨22用于与驱动元件40的凸柱422配合，第二导轨23用于与第二连杆30的导向柱33配合。
第二连杆30为钥匙形结构，上部为环形结构，中间设置有矩形通槽31，下部为杆体32，导向柱33设置在杆体32朝向第一连杆20的一面。通槽31的位置与第一导轨22的位置配合，以便驱动元件40驱动第一连杆20和第二连杆30，第二连杆30可通过导向柱33在第二导轨23上转动或滑动。驱动元件40的凸缘421位于通槽31内，凸缘421通过推动通槽31使第二连杆30移位，从而推动导风板本体50旋转。
在实施时，当导风板闭合时，驱动元件40的连接杆42位于第二导轨23所在直线上，且指向远离第二导轨23的方向；当需要导风板本体50向下开口时，使驱动元件40以第一旋转方向转动，凸柱422被带动朝向第一导轨22的第一端运动，在运动过程中，凸柱422对第一导轨22产生一个分力驱动第一连杆20向外伸出并将导风板本体50推出机身，导风板本体50由于与第二连杆30铰接，因此导风板本体50移动的同时将带动第二连杆30同步向外伸出，在此过程中，第二连杆30与第二连杆30相对静止，当凸柱422到达第一导轨22的第一端时，凸缘421开始与矩形通槽31的下边缘接触，并逐渐抵住矩形通槽31的下边缘，推动第二连杆30移动，由于第一连杆20只能做伸 缩运动，第二连杆30与第一连杆20只在导向柱33与第二导轨23有配合关系，因此第二连杆30将在凸缘421的推力下发生偏移，并推动导风板本体50转动。当导风板本体50与第二限位结构25的第一倾斜面接触时，导风板本体50到达最大开口角度，此时由于导风板受到抵压，电机负载突然增大，此时电机停止运动，导风板位于该最大开口角度进行送风。若在导风板本体50与第二限位结构25的第一倾斜面接触之前，第二连杆30先与第一限位结构24的第二侧面接触，则驱动元件40将推动第二连杆30在保持与第二侧面接触的同时，沿第二导轨23下移，使导风板本体50的开口角度更大，直至导风板本体50与第一限位结构24的第一倾斜面相抵时，电机停止运动。
当进行开口方向切换时，假设实现导风板本体50向上开口进行送风时电机逆时针带动驱动元件40转动，当要切换至导风板本体50向下开口送风时电机仅需改变转动方向，顺时针转动，此时导风板需先达到闭合，电机继续带动驱动元件40顺时针转动即可切换至制热开口角度。导风板本体50开口方向的切换，仅需控制电机正反转实现。
导风板的停止运动可以从两方面实现，一方面通过电机控制导风板本体50的运转角度，当电机停止时，没有力驱动导风板运动，则导风板本体50停止运动，另一方面当导风板本体50与第一限位结构24或第二限位结构25相抵时，导风板本体50无法再继续转动，同时根据电机传动轴的转动角度计算电机的运动步数，当达到最大转动角度时，电机停止转动。
结合图10所示，本公开实施例提供一种空调器，包括如上的空调室内机。
本申请采用驱动元件40作为驱动结构，第一连杆20作为推出导风板本体50的主要结构，第二连杆30作为推动导风板旋转的主要结构，第一连杆20与第二连杆30配合实现导风板的大角度旋转，其中，驱动元件40上设置有凸柱422，导风板驱动组件通过凸柱422驱动第一连杆20推出导风板本体50，通过驱动元件40的凸缘421驱动第二连杆30转动进而推动导风板本体50旋转。当凸柱422位于第一导轨22的第一区域221或第二区域222时，导风板被第一连杆20推出到机身外侧，当凸缘421位于通槽31的第三区域311时，导风板处于向下开口状态，当凸缘421位于通槽31的第四区域312时，导风板本体50处于向上开口状态。
由于本申请的驱动元件40可以驱动第一连杆20和第二连杆30，本申请的导风板驱动组件采用一组驱动结构即可实现导风板的推出和旋转动作，解决驱动结构数量多导致空调器成本升高、导风板运动可靠性低的问题。
