Description

一种电动汽车进风格栅装置以及控制方法
本申请要求于2016年01月26日提交中国专利局、申请号为201610053755.7、发明名称为“一种电动汽车进风格栅装置以及控制方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及电动汽车技术领域，更具体地说，涉及一种电动汽车进风格栅装置以及控制方法。
背景技术
目前，电动汽车的空调一般采用平行流式冷凝器，当空调进行制热时，制冷剂在平行流式冷凝器中蒸发吸热时容易结霜。当前的电动汽车化霜时，利用压缩机排出的高温制冷剂进行热气融霜，但是，车辆行驶时，位于电动汽车前侧的进风格栅的进风会带走进入平行流式冷凝器中高温制冷剂的大量热量，延长了化霜时间，增加电动汽车的能源消耗，缩短了续航里程。
因此，如何缩短电动汽车的化霜时间，减少电动汽车的能源消耗，延长了续航里程，成为本领域技术人员亟待解决的技术问题。
发明内容
有鉴于此，本发明的目的在于提供一种电动汽车进风格栅装置，以缩短电动汽车的化霜时间，减少电动汽车的能源消耗，延长了续航里程；
本发明的另一个目的在于提供一种电动汽车进风格栅装置的控制方法。
为实现上述目的，本发明提供如下技术方案：
一种电动汽车进风格栅装置，包括：
设置在电动汽车前侧的进风格栅，所述进风格栅上设置有驱动所述进风格栅开启或关闭的电机；以及
控制器，所述控制器获知所述电动汽车处于化霜模式时，所述电机驱动所述进风格栅关闭，所述控制器获知所述电动汽车处于正常模式时，所述电机驱动所述进风格栅开启。
优选地，在上述电动汽车进风格栅装置中，还包括设置在冷凝器处的感温包，所述感温包用于检测所述冷凝器的实时温度，当所述实时温度大于所述控制器的预设温度时，所述电机驱动所述进风格栅开启。
优选地，在上述电动汽车进风格栅装置中，所述进风格栅，包括：安装在所述电动汽车上的支撑架；
铰接在所述支撑架上的多个格栅板；以及
与所述支撑架平行设置的连杆，多个所述格栅板铰接在所述连杆上；当位于第一状态时，多个所述格栅板与风向互相平行；当位于第二状态时，相邻的所述格栅板互相紧挨。
优选地，在上述电动汽车进风格栅装置中，所述电机设置在多个所述格栅板中的一个所述格栅板上。
本发明还提供了一种电动汽车进风格栅装置控制方法，包括步骤：
(1)获知电动汽车处于化霜模式，电机驱动进风格栅关闭；
(2)获知电动汽车处于正常模式，电机驱动进风格栅开启。
优选地，在上述电动汽车进风格栅装置控制方法中，所述步骤(1)还包括：获取冷凝器的实时温度，当所述实时温度大于所述预设温度时，所述电机驱动进风格栅开启。
优选地，在上述电动汽车进风格栅装置中，所述进风格栅，包括：安装在所述电动汽车上的支撑架；
铰接在所述支撑架上的多组格栅板；以及
与所述支撑架平行设置的多个连杆，每组所述格栅板铰接在一个所述连杆上；当位于第一状态时，多组所述格栅板与风向互相平行；当位于第二状态时，相邻的所述格栅板互相紧挨。
优选地，在上述电动汽车进风格栅装置中，所述电机设置在多组所述格栅板中的一个所述格栅板上。
从上述的技术方案可以看出，本发明提供的电动汽车进风格栅装置中电动汽车处于化霜模式时，所述电机驱动所述进风格栅关闭，所述控制器获知所述电动汽车处于正常模式时，所述电机驱动所述进风格栅开启。由此可见当电动 汽车处于化霜模式时，前侧的进风格栅不进风，因此，不会将冷凝器上的热量带走，缩短了化霜时间，减小电动汽车的能源消耗，延长了续航里程。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例所提供的电动汽车进风格栅装置的结构示意图；
图2为本发明实施例所提供的电动汽车进风格栅第一状态时的结构示意图；
图3为本发明实施例所提供的电动汽车进风格栅第二状态时的结构示意图；
图4为本发明实施例所提供的电动汽车进风格栅装置的控制方法流程示意图。
其中，100为控制器、200为冷凝器、300为进风格栅、301为支撑架、302为格栅板、303为连杆、400为电机、500为感温包。
具体实施方式
本发明的核心在于提供一种电动汽车进风格栅装置，以缩短电动汽车的化霜时间，减少电动汽车的能源消耗，延长了续航里程；本发明的另一个核心在于提供一种电动汽车进风格栅装置的控制方法。
以下，参照附图对实施例进行说明。此外，下面所示的实施例不对权利要求所记载的发明内容起任何限定作用。另外，下面实施例所表示的构成的全部内容不限于作为权利要求所记载的发明的解决方案所必需的。
请参阅图1至图3，图1为本发明实施例所提供的电动汽车进风格栅装置的结构示意图；图2为本发明实施例所提供的电动汽车进风格栅第一状态时的结构示意图；图3为本发明实施例所提供的电动汽车进风格栅第二状态时的结构示意图。
本发明实施例提供的电动汽车进风格栅装置包括控制器100、进风格栅300和电机400，其中，进风格栅300设置在电动汽车前侧，驱动电机400所述进风格栅300开启或关闭，控制器100获知所述电动汽车处于化霜模式时，所述电机400驱动所述进风格栅300关闭，所述控制器100获知所述电动汽车处于正常模式时，所述电机400驱动所述进风格栅300开启。
本发明提供的电动汽车进风格栅装置中电动汽车处于化霜模式时，所述电机400驱动所述进风格栅300关闭，所述控制器100获知所述电动汽车处于正常模式时，所述电机400驱动所述进风格栅300开启。由此可见当电动汽车处于化霜模式时，前侧的进风格栅300不进风，因此，不会将冷凝器200上的热量带走，缩短了化霜时间，减小电动汽车的能源消耗，延长了续航里程。
需要说明的是，本发明实施例中的控制器100为本领域公知的结构，并应用该控制器100本身所具有的功能来解决现有技术存在的问题，并未对控制器100的功能进行改进。
为了优化上述技术方案，上述电动汽车进风格栅装置还包括设置在冷凝器200处的感温包500，所述感温包500用于检测所述冷凝器200的实时温度，当所述实时温度大于所述控制器100的预设温度时，所述电机400驱动所述进风格栅300开启。
其中，该预设温度根据所处地域的不同，车型的不同有所差别。当实时温度达到预设温度时，说明冷凝器200上的霜已经融化完毕，此时进风格栅300开启，新风通过进风格栅300进入车内，这样可以让冷凝器200上的冷凝水快速排出，避免冷凝器200上残留的水在空调切换为制热模式时又被冻结成冰霜，影响后续空调制热运行的性能。
本发明实施例中的进风格栅300能够灵活的开启或关闭，其中，开启或关闭通过电机400进行驱动，而实现进风和关闭的进风格栅300的结构有很多。本发明实施例具体介绍其中一种，该所述进风格栅300，包括支撑架301、格栅板302和连杆303，其中，支撑架301安装在所述电动汽车上，用于支撑整个进风格栅300，格栅板302的数量为多个，多个格栅板302铰接在支撑架301上，且相邻的格栅板302相互平行；连杆303与支撑架301相互平行，且多个格栅板302铰接在连杆303上，支撑架301、格栅板302和连杆303形成平行四连杆303机构。当电机400驱动多个格栅板302中的一个格栅板302转动时，剩余的格栅板302也会进行相同的运动，当位于第一状态时，多个所述格栅板302与风向互相平 行；当位于第二状态时，相邻的所述格栅板302互相紧挨。其中第一状态时，进风格栅300处于开启状态，第二状态时，进风格栅300处于关闭状态。
所述电机400设置在多个所述格栅板302中的一个所述格栅板302上。为了保证受力的均匀性，电机400设置在多个格栅板302中位于中间的一个格栅板302上。
或者，支撑板上设置几组格栅板302，相邻的几个格栅板302为一组，每组格栅板302连接有一个连杆303，每组格栅板302上设置有一个电机400，以驱动格栅板302转动以实现进风格栅300的开启或关闭。
本发明还公开了一种电动汽车进风格栅装置控制方法，包括步骤：
(1)获知电动汽车处于化霜模式，电机400驱动进风格栅300关闭。
化霜模式下，进风格栅300关闭后汽车前侧没有进风，冷凝器200上的霜会快速融化。冷凝器200的热量不会被吸收走，因此，缩短了化霜时间，降低了能耗。
在化霜过程中，获取冷凝器200的实时温度，当所述实时温度大于所述预设温度时，所述电机400驱动进风格栅300开启。当控制器100检测到管温感温包500的实时温度达到预设温度时，说明冷凝器200上的霜已经融化干净，此时控制器100控制电机400驱动进风格栅300处于打开状态，电动汽车空调继续按照化霜模式运行，这样可以让冷凝器200上的冷凝水快速排出，避免冷凝器200上残留的水在空调切换为制热模式时又被冻结成冰霜，影响后续空调制热运行的性能。
(2)获知电动汽车处于正常模式，电机400驱动进风格栅300开启。
进风格栅300通常状态下为开启，当电动汽车处于正常模式时，进风格栅300处于开启状态，便于冷凝器200换热。可有效提高化霜效果，提高乘员的舒适性，降低电动汽车空调能源消耗。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
