具体实施方式
首先，本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合。
其次，需要说明的是，在本发明的描述中，术语“内”、“外”等指示的方向或位置关系的术语是基于附图所示的方向或位置关系，这仅仅是为了便于描述，而不是指示或暗示装置或构件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“相连”、“连接”应做广义理解，例如，可以是固定连接，也可 以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个构件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
本发明实施例提供一种空调室外机，如图1和图3所示，空调室外机至少包括壳体10、电机20、风扇21以及热交换器172，壳体10形成有空腔，电机20、风扇21以及热交换器172设置在壳体10的空腔中，其中电机20的输出轴连接风扇21，电机20用于驱动风扇21转动，热交换器172用于与周围环境的空气进行热交换，风扇21优选靠近热交换器172设置，风扇21转动的时候，使得热交换器172周围的经过热交换的空气流动进而排到空调室外机的外部，优选地，风扇21位轴流风扇。
本发明的实施例的空调室外机能够与配对的空调室内机装配成空调，该空调例如具有制冷模式和制热模式，在制冷模式下，空调室外机的热交换器172向周围环境放热，即，该模式下的热交换器172为冷凝器，在制热模式下，空调室外机的热交换器172向周围环境吸热，即，该模式下的热交换器172为蒸发器，无论空调处于制冷模式还是制热模式下，也即，无论室外机的热交换器172为蒸发器还是冷凝器，都需要电机20驱动风扇21转动，以使得热交换器172周围环境的空气流动起来，实现更好的热交换，显然，空调室外机运行时，驱动风扇21的电机20的使用率很高。
在一个可行的实施例中，如图3所示，实施例中的空调室外机包括发电机30和蓄电池70，驱动风扇21转动的空调室外机中的电机20，其输出轴同时连接风扇21和发电机30的输入轴，发电机30的输入轴上安装发电机30的转子，如此，在电机20驱动风扇21转动的同时实现发电机30发电，可行地，本实施例中的空调室外机还包括蓄电池70，蓄电池70和发电机30电连接，当发电机30运行的时候，产生的电能被存储在蓄电池70中。
存储在蓄电池70中的电能可以用于任何用途，包括用于驱动空调的运行，当然，电机20运行使得发电机30发电产生电能的过程，并不意味着电机20运行对应的全部能量都可以转化为电能，表现为：空调运行N1个小时，对应的发电机30产生的电能能够驱动空调运行N2个小时，显然，N1大于N2，这种回收能量的效率，符合能量转化的客观原理。
在一个可行的实施例中，如图3所示，空调室外机还包括变速器80，电 机20的输出轴与变速器80的输入轴连接，变速器80的输出轴与发电机30的输入轴连接，经变速器80变速后，可以使得不在安全转速范围内的电机20的输出轴的转速，转化为可以输入发电机30的转速，进而使得驱动风扇21运行的电机20的输出运动的利用效率进一步增大，进而达到更好的节能效果。具体地，电机20的输出轴与变速器80的输入轴通过联轴器相连，变速器80的输出轴与发电机30的输入轴通过联轴器器相连。
可以理解，用于连接电机20的输出轴和变速器80的输入轴的联轴器可以是现有技术的任何联轴器，例如可以是齿式联轴器、弹性联轴器等中的一种，同理，用于连接变速器80的输出轴和发电机30的输入轴的联轴器也可以是现有技术的任何联轴器，例如可以是齿式联轴器、弹性联轴器等中的一种。
在上述实施例的进一步的实施例中，变速器80包括第一齿轮和第二齿轮以及多级中间传动齿轮，第一齿轮安装在变速器80的输入轴上，第二齿轮安装在变速器80的输出轴上，第一齿轮和第二齿轮通过多级中间传动齿轮连接，电机20的输出轴与变速器80的输入轴相连，变速器80的输出轴与发电机30的输入轴相连。
本发明实施例的空调室外机，如图3所示，还包括第一制动器40，第一制动器40包括相互配合的第一固定部和第一旋转部，第一固定部相对壳体10固定设置，第一旋转部设置在变速器80的输出轴或者发电机30的输入轴上，第一制动器40能够在变速器80的输出轴或者发电机30的输入轴的转速小于等于第一转速或者大于等于第二转速时，使得变速器80的输出轴与发电机30的输入轴停止转动，在变速器80的输出轴或者发电机30的输入轴的转速大于第一转速且小于第二转速时，保证变速器80的输出轴与发电机30的输入轴的正常转动，显然，第一转速小于第二转速。第一制动器40的设置可以保证发电机30的正常运行，进而保证本发明实施例的空调室外机的可靠使用。
本发明实施例的空调室外机，如图3所示，还包括第二制动器50，第二制动器50包括相互配合的第二固定部和第二旋转部，第二固定部相对壳体10固定设置，第二旋转部设置在变速器80的输入轴或者电机20的输出轴上，第二制动器50能够在变速器80的输入轴或者电机20的输出轴的转速小于等于第三转速或者大于等于第四转速时，使得变速器80的输入轴与电机20 的输出轴停止转动，在变速器80的输入轴或者电机20的输出轴的转速大于第三转速且小于第四转速时，保证变速器80的输入轴与电机20的输出轴的正常运行，显然，第三转速小于第四转速。本发明实施例的空调室外机，在第一制动器40的基础上设置第二制动器50，第一制动器40可以保证传递到发电机30的转速在安全的范围内，第二制动器50的设置可以保证电机20的输出转速发现异常的时候及时使得变速器80的输入轴与电机20的输出轴停止转动，进而避免经变速器80调整转速后的变速器80的输出轴或者发电机30的输入轴的转速不在安全的范围内，此外，在第一制动器40出现异常的时候，第二制动器50也可以起到保护发电机30的作用。
显而易见地，第一制动器40和第二制动器50的结构可以完全一样，也可以不一样，例如，第一制动器40可以是鼓式制动器，第二制动器50可以是鼓式制动器或者盘式制动器，再例如，第一制动器40可以是盘式制动器，第二制动器50可以是鼓式制动器或者盘式制动器。
空调室外机还包括箱体90，如图3所示，第一制动器40、第二制动器50、变速器80以及发电机30设置在箱体90内，箱体90用于保护第一制动器40、第二制动器50、变速器80以及发电机30。具体地，发电机30通过支撑架92将发电机30固定在箱体90的内部。
在一个具体的实施例中，箱体90的形状是立方体，立方体形状的箱体90的其中一个方向上的棱边的尺寸大于其他两个方向上的棱边的尺寸，定义棱边的尺寸大的方向为长度方向，第一制动器40、变速器80、第二制动器50以及发电机30依次沿着箱体90的长度方向设置在箱体90的内部。
本发明的实施例的空调室外机，如图2所示，壳体10的空腔的腔壁上设置有格栅结构121，风扇21转动使得壳体10内部经过热交换的空气经格栅结构121的格栅孔流动到壳体10的外侧。
进一步，如图2所示，格栅结构121包括同心设置的多个圆形格栅栅条1212和辐射设置的多个弧形格栅栅条1213，每个弧形格栅栅条1213与多个圆形格栅栅条1212连接，圆形格栅栅条1212和弧形格栅栅条1213形成格栅孔。
箱体90设置在壳体10的外侧，箱体90与格栅结构121相对设置，格栅结构121上设置有避让孔，电机20的输出轴穿过避让孔伸入箱体90内与变速器80的输入轴连接，在格栅结构121上设置有避让孔的方式能够使得 各零部件的布局更加合理，减小壳体10的结构尺寸。
优选地，如图2所示，格栅结构121包括外边框1211，格栅结构121的格栅孔位于外边框1211的内周侧，且格栅结构121的格栅孔位于避让孔的外周侧，空调室外机还包括安装支架122，安装支架122固定在外边框1211上，箱体90通过设置在其外侧壁上的固定座91安装固定在安装支架122上。
如图2所示，安装支架122包括环形圈1221和多个辐射条1222，每个辐射条1222的一端连接环形圈1221，每个辐射条1222的另一端连接外边框1211，电机20的输出轴穿过环形圈1221的孔以及格栅结构121上的避让孔与变速器80的输入轴连接，箱体90通过设置在其外侧壁上的固定座91安装在环形圈1221或者辐射条1222或者同时设置在环形圈1221和辐射条1222上。优选地，环形圈1221的孔与避让孔同心设置，以使得电机20的输出轴穿过避让孔和环形圈1221的孔时不与环形圈1221和格栅结构121造成干涉。
如图3所示，本发明实施例的空调室外机还包括电池箱60，蓄电池70设置在电池箱60的内部，电池箱60能够对蓄电池70进行保护，避免处于室外的空调室外机受外力作用造成损坏。
优选地，电池箱60设置在箱体90的外侧，电池箱60靠近格栅结构121设置，如此，可以减小电池箱60距离箱体90的靠近格栅结构121的一侧的距离，进而在电池箱60的质量和设置在电池箱60内部的蓄电池70的质量不变的情况下，降低电池箱60和蓄电池70对用于连接箱体90和安装支架122的结构件的转矩，保证箱体90、设置在箱体90内的第一制动器40、第二制动器50、变速器80以及发电机30、电池箱60以及设置在电池箱60内部的蓄电池70的安装可靠性。
例如，在一个具体的实施方式中，箱体90与固定座91固定连接，固定座91通过螺栓安装在安装支架122上，当电池箱60安装在箱体90的靠近格栅结构121的一侧时，箱体90、设置在箱体90内的第一制动器40、第二制动器50、变速器80以及发电机30、电池箱60以及设置在电池箱60内部的蓄电池70对螺栓的转矩就会减小，保证通过螺栓固定箱体90的可靠性。

本发明的空调室外机的工作原理为：风扇21安装在电机20的输出轴上，电机20的输出轴同时与发电机30的输出轴连接，在电机20驱动风扇21转动以使得壳体10内部经过热交换的空气流动到壳体10的外侧的时候，电机20的输出轴运行使得发电机30的输入轴转动，进而在电机20驱动风扇21 转动的时候，使得发电机30运行，实现发电，本发明的这种空调室外机，不仅可以实现现有技术的空调室外机的正常功能，而且可以增加电机20的输出运动的使用效率，进而节约能源，增加空调室外机的功能。
