下面参考图1-图5描述根据本申请实施例的门体总成100。
如图1-图5所示，根据本申请一个实施例的门体总成100包括：可转动的门体10和自动开关门装置20，自动开关门装置20设置在门体10内，且自动开关门装置20包括：驱动器22、第一离合装置23、推门件24和第二离合装置25。
驱动器22具有第一驱动轴221和第二驱动轴222，第一离合装置23具有分离状态和结合状态，且第一离合装置23包括第一输入端和第一输出端，第一输入端与第一驱动轴221连接，推门件24与第一输出端连接，第一离合装置23处于结合状态下，第一离合装置23的第一输出端驱动推门件24移动，从而使门体10转动，门体10转动至预设角度的条件下，即门体10沿转轴11顺时针或逆时针转动预设角度时，控制第一离合装置23处于分离状态，其中，这里预设角度的范围为1°-30°。
第二离合装置25也具有分离状态和结合状态，且第二离合装置25包括第二输入端和第二输出端，第二输入端与第二驱动轴222连接，第二输出端适于与门体10的转轴11连接，从而可以在第二离合装置25处于结合状态下，第二输出端驱动门体10从上述的预设角度继续转动，直至门体10完全打开。
根据本申请实施例的门体总成100，设置带有离合装置的自动开关门组件20，通过驱动器22驱动第一离合装置23处于结合状态，以驱动推门件24移动将门体10推开，再通过驱动器22驱动第二离合装置25处于结合状态，以与转轴11的配合将门体10转开，开门过程顺畅，断电后可以手动开关门，通过离合装置实现无缝切换，有效减少噪音，并通过离合器机构实现对驱动器22的保护，可靠性高，使用寿命长，且不改变整机外观，使得门体10上无杂乱的可见部件，提高了用户体验感，提升了产品的竞争力。
根据本申请的一个实施例，推门件24相对于门体10可移动，且门体10的背面具有适于推门件24伸出的穿孔，推门件24在第一离合装置23的第一输出端的驱动下移动，推门件24穿过门体10背面的穿孔，直至止抵在箱体或其他使用该门体总成的设备的稳定结构上，由于该箱体或稳定结构保持不动，从而可以给推门件24一定的反作用力，进而反推门体10发生转动。门体10未转动时，推门件24隐藏的门体10内，且不伸出穿孔，从而不影响美观。
如图1所示，根据本申请的一个实施例，自动开关门装置20还包括壳体21，壳体21设置在门体10的顶部，即自动开关门装置20固定在门体10的顶部，壳体21也可以设置在门体10的底部，当然，还可以在门体10的底部和顶部均设置自动开关门装置20，其中，自动开关门装置20可以通过螺钉、螺栓或卡扣等结构固定在门体10上。
驱动器22、第一离合装置23、推门件24和第二离合装置25设置在壳体21内，壳体21内具有滑槽，滑槽沿门体10的打开方向(例如门体10的厚度方向，如图4所示的前后方向)延伸，推门件24可以沿滑槽的长度方向移动，从而使推门件24贴合在自动开关门装置20的壳体21内，并只能在门体10的开关门方向运动，即滑槽实现导向作用。通过设置壳体21，使得门体10上无杂乱的可见部件，且不改变整机原始外观，提高了用户体验，提升了产品的竞争力。
在一些实施例中，门体10打开时，第一离合装置23处于结合状态，第一离合装置23的第一输出端驱动推门件24在开门方向移动，从而使门体10打开；门体10关闭时，第一离合装置23处于结合状态，第一离合装置23的第一输出端反向驱动推门件24移动，使得推门件24收回至壳体21的滑槽内。
根据本申请的一个实施例，驱动器22工作且第一离合装置23通电的条件下，第一离合装置23处于结合状态；第一离合装置23断电的条件下，第一离合装置23处于分离状态。
在一些实施例中，驱动器22工作且第一离合装置23通电时，第一离合装置23处于结合状态，从而使第一离合装置23的第一输出端驱动推门件24移动，使门体10转动，门体10转动至预设角度的条件下，第一离合装置23断电，使得第一离合装置23处于分离状态，推门件24停止移动，门体10停止转动。通过驱动器22驱动第一离合装置23处于结合状态，以驱动推门件24移动将门体10推开，开门过程顺畅，通过第一离合装置23实现无缝切换，有效减少噪音，同时实现对驱动器22的保护，可靠性高。

在一些示例中，第一传动组件232包括至少一个第一齿轮2321，第一齿轮2321与第一驱动轴221连接，推门件24设有多个啮合齿241，多个啮合齿241沿线性方向排布，且啮合齿241与第一齿轮2321啮合，第一传动组件232转动，通过推门件24的啮合齿241与第一齿轮2321啮合，使得推门件24相对于门体10移动，门体10的背面具有适于推门件24伸出的穿孔，推门件24穿过穿孔，止抵在箱体或其他使用该门体总成的设备的稳定结构上，由于该箱体或稳定结构保持不动，从而可以给推门件24一定的反作用力，进而反推门体10发生转动。
在一些示例中，第一传动组件232包括第一齿轮2321和多个减速齿轮，第一传动组件232转动时，可以通过多个减速齿轮的转动带动第一齿轮2321的转动，从而降低第一齿轮2321的转速，避免推门件24的移动速度过大，导致给门体10或其他结构造成的损伤。
如图3所示，在一些示例中，第一离合器231包括：第一主动盘2311和第一从动盘2312，第一主动盘2311与第一驱动轴221连接，第一从动盘2312与第一传动组件232连接，且第一从动盘2312与第一主动盘2311可分离地连接，第一离合器231处于结合状态下，第一从动盘2312与第一主动盘2311连接，从而带动第一传动组件232转动；第一离合器231处于分离状态下，第一从动盘2312与第一主动盘2311分离，第一传动组件232停止转动。
根据本申请的一个实施例，驱动器22工作且第二离合装置25通电的条件下，第二离合装置25处于结合状态；第二离合装置25断电的条件下，第二离合装置25处于分离状态。具体而言，驱动器22工作且第二离合装置25通电，第二离合装置25处于结合状态，从而使第二离合装置25的第一输出端驱动门体10的转轴11发生相对转动，使门体10转动，门体10转动至打开位置，第二离合装置25断电，使得第二离合装置25处于分离状态，门体10停止转动。通过驱动器22驱动第二离合装置25处于结合状态，以与转轴11的配合将门体10转开，开门过程顺畅，断电后可以手动开关门，通过第二离合装置25实现无缝切换，有效减少噪音，同时实现对驱动器22的保护，可靠性高，使用寿命长。
如图2所示，根据本申请的一个实施例，第二离合装置25包括：第二离合器251和第二传动组件252，第二离合器251具有输入轴和输出轴，第二离合器251的输入轴形成第二输入端，第二传动组件252的输入端与第二离合器251的输出轴连接，第二传动组件252的输出端形成第二输出端，即通过第二离合器251的离合控制第二传动组件 252的转动，从而控制门体10与转轴11的相对转动。
在一些示例中，第二传动组件252包括至少一个主动锥齿轮2522，主动锥齿轮2522与第二驱动轴222连接，门体10的转轴11设有从动锥齿轮111，从动锥齿轮111与主动锥齿轮2522啮合，第二传动组件252运行，通过主动锥齿轮2522与转轴11上的从动锥齿轮111的啮合，由于转轴11的位置是固定不变的，在从动锥齿轮111与主动锥齿轮2522的配合下，使得门体10相对于转轴11发生转动，从而使门体10完全打开。
在进一步的示例中，第二传动组件252包括至少一个第二齿轮2521，第二齿轮2521的一端与第二驱动轴222连接，第二齿轮2521的另一端与主动锥齿轮2522连接，从而在第二传动组件252转动的条件下，可以通过第二齿轮2521转动带动主动锥齿轮2522的转动，从而降低主动锥齿轮2522的转速，避免门体10转动速度过大，导致给门体10造成损伤。
如图3所示，在一些示例中，第二离合器251包括：第二主动盘2511和第二从动盘2512，第二主动盘2511与第二驱动轴222连接，第二从动盘2512与第二传动组件252连接，且第二从动盘2512与第二主动盘2511可分离地连接。

下面结合图1-图5描述根据本申请的制冷设备200的一个具体的实施例。
制冷设备200包括箱体30、控制器、角度检测装置和门体总成100，角度检测装置用于检测门体10的打开角度，箱体30的一侧具有开口，门体总成100可转动地设置在箱体30的开口处。箱体30上设有支撑台40，支撑台40位于门体总成100的下部，门体总成100包括门体10和自动开关门装置20，门体10由发泡门体和玻璃面板组成，门体10具有转轴11，转轴11固定在支撑台40上，转轴11的下端具有从动锥齿轮111，控制器与自动开关门装置20通讯，用于控制自动开关门装置20的工作实现门体10的自动开关。
自动开关门装置20具有壳体21，壳体21通过螺钉和门体10固定在一起，自动开关门装置20包括驱动器22、第一离合装置23、推门件24和第二离合装置25，驱动器22、第一离合装置23、推门件24和第二离合装置25均设置在壳体21内，驱动器22具有第一驱动轴221和第二驱动轴222，壳体21内具有滑槽，滑槽沿门体10的打开方向延伸，推门件24可以沿滑槽的长度方向移动，且门体10的背面具有适于推门件24伸出的穿孔，推门件24上表面具有多个啮合齿241，多个啮合齿241沿门体10的打开方向排布。
第一离合装置23具有分离状态和结合状态，第一离合装置23包括第一离合器231和第一传动组件232，第一离合器231的输入轴形成第一输入端，第一输入端与第一驱动轴221连接，第一离合器231包括第一主动盘2311和第一从动盘2312，第一主动盘2311与第一驱动轴221连接，第一传动组件232包括第一齿轮2321和多个减速齿轮，减速齿轮与第一从动盘2312连接，第一齿轮2321形成第一输出端，第一齿轮2321与推门件24的啮合齿241啮合连接。
第二离合装置25也具有分离状态和结合状态，第二离合装置25包括第二离合器251和第二传动组件252，第二离合器251的输入轴形成第二输入端，第二输入端与第二驱动轴222连接，第二离合器251包括第二主动盘2511和第二从动盘2512，第二主动盘2511与第二驱动轴222连接，第二传动组件252包括第二齿轮2521和主动锥齿轮2522，第二齿轮2521与第二从动盘2512连接，主动锥齿轮2522的输出端形成第二输出端，主动锥齿轮2522与门体10的从动锥齿轮111啮合连接。
驱动器22工作且第一离合装置23通电的条件下，第一离合器231处于结合状态，第一从动盘2312与第一主动盘2311连接，驱动第一齿轮2321转动，使推杆24移动；第一离合装置23断电的条件下，第一离合器231处于分离状态，第一从动盘2312与第一主动盘2311分离。
驱动器22工作且第二离合装置25通电的条件下，第二离合器251处于结合状态，第二从动盘2512与第二主动盘2511连接，驱动第二齿轮2521和主动锥齿轮2522转动； 第二离合装置25断电的条件下，第二离合器251处于分离状态，第二从动盘2512与第二主动盘2511分离。其中，第一离合装置23和第二离合装置25与驱动器22的转动轴可以保持同心，但第一离合装置23和第二离合装置25不同时通电。
检测到自动开门信号的条件下，控制器控制驱动器22工作且使第一离合装置23通电，使第一离合器231处于结合状态，第一主动盘2311与第一从动盘2312连接，第一齿轮2321在驱动器22的驱动作用下转动，推门件24的啮合齿241与第一齿轮2321啮合，使得推门件24相对于门体10移动，并穿过门体10的背面的穿孔，止抵在箱体30上，箱体30给推门件24一定的反作用力，使得门体10发生转动。
角度检测装置检测到门体10的打开角度为10°的条件下，控制器控制第一离合装置23断电，使第一离合器231处于分离状态，第一主动盘2311与第一驱动轴221断开连接，第一齿轮2321失去动力来源，停止转动，同时控制第二离合装置25通电，此时第二离合器251处于结合状态，第二主动盘2511与第二从动盘2512连接，第二齿轮2521和主动锥齿轮2522在驱动器22的驱动作用下转动，主动锥齿轮2522与转轴11上的从动锥齿轮111啮合，由于转轴11固定在支撑台40上保持不动，从而使得门体10继续转动至默认开门角度。
检测到自动关门信号的条件下，控制器控制驱动器22工作且使第一离合装置23通电，第一主动盘2311与第一从动盘2312连接，第一齿轮2321在驱动器22的驱动作用下反向转动，推门件24的啮合齿241通过与第一齿轮2321啮合，反方向移动至壳体21内部，此时控制器控制第一离合装置23断电，使第一离合器231处于分离状态，第二离合装置25通电，使第二离合器251处于结合状态，第二齿轮2521和主动锥齿轮2522在驱动器22的驱动作用下反方向转动，使门体10逐渐关闭。
开门或关门过程中受到外力的条件下，角度检测装置检测到异常后，控制器控制驱动器22断电，且断电前第一离合器23和第二离合器25均为打滑状态以保护驱动器22、第一齿轮2321、第二齿轮2521和主动锥齿轮2522，门体20实现悬停。
停电的条件下，第一离合装置23和第二离合装置25均为断电状态，第一主动盘2311和第一从动盘2312分离，第二主动盘2511和第二从动盘2512也分离，此时用户可以通过施加外力来实现门体10的开关，即断电时不影响用户的正常使用。
