具体实施方式
下面参照附图描述本发明的示例性实施方式。
本说明书中提到的轴向对应于图1至图3中的上下方向，轴向一端或轴向一侧指图1至图3中的上端或上侧，轴向另一端或轴向另一侧指图1至图3中的下端或下侧。虽然使用了“轴向”这一术语，但是壳体8、移动壳7、弹性材料5和推杆4等不必须为圆筒状或圆柱状。
首先，参照图1说明根据本发明的一个实施方式的车辆格栅总成的结构。
参照图1，本发明提供一种车辆格栅总成，该车辆格栅总成包括可转动的格栅1和车辆格栅驱动装置。格栅1可以绕着转轴101转动。车辆格栅驱动装置可以驱动格栅1打开，以允许风进入发动机舱，冷却发动机等结构。车辆格栅驱动装置还可以保持格栅1关闭，阻止风进入发动机舱，保持发动机等的工作温度。
车辆格栅驱动装置包括连接构件2，连接构件2的一端通过转动接头201连接到格栅1。连接构件2的另一端通过转动接头202连接到后述的可动板9。 转动接头201和转轴101在格栅1的宽度方向(图1中的上下方向)上位置分开，从而可以经由连接构件2带动格栅1绕转轴101转动。
车辆格栅驱动装置还包括壳体8和能够在壳体8中往复移动的圆板状或圆环板状的可动板9。壳体8包括：筒状体801；设置于筒状体801的靠近格栅1的轴向一端的挡圈803，挡圈803用于限制可动板9的轴向移动范围；设置于筒状体801的远离格栅1的轴向另一端的连接板802，连接板802用于将壳体8通过例如螺栓等的固定元件固定连接到车身3。
车辆格栅驱动装置还包括移动组件。移动组件包括移动壳7，移动壳7与可动板9连接在一起从而能够一起移动。移动壳7内装有例如蜡等的体积会随着温度变化而变化的热膨胀材料6。移动壳7内还装有例如橡胶等的弹性材料5。弹性材料5固定到移动壳7的轴向一端(上端)。在弹性材料5的至少轴向另一端侧(下侧)具有足够量的热膨胀材料6，使得在热膨胀材料6受热膨胀时能够将弹性材料5压缩预定的量。移动组件还包括推杆4，推杆4的一端固定连接到车身3，推杆4的另一端插入到弹性材料5的孔501中。优选地，推杆4的另一端具有锥状部。孔501包括与推杆4的锥状部对应的锥孔部。
车辆格栅驱动装置还包括设置在壳体8内且围绕移动壳7固定设置的冷却液容器12。冷却液容器12允许移动壳7轴向移动。冷却液容器12设有入口10和出口11。如空心箭头F1和F2所示，用于冷却发动机等的冷却液可以从入口10进入冷却液容器12并从出口11离开。优选地，对发动机等车辆部件进行冷却后的变暖的冷却液从入口10流入冷却液容器12。
车辆格栅驱动装置还包括设置在壳体8中的弹簧13。弹簧13例如可以为处于压缩状态的螺旋弹簧。弹簧13的一端压抵可动板9，另一端定位在壳体8内。弹簧13对可动板9施加使可动板9移动到壳体8的轴向一端的力。在一个非限制性的示例中，弹簧13的另一端可以压抵冷却液容器12。在另一个非限制性的示例中，弹簧13的另一端压抵固定设置在壳体8中的挡板804。
下面参照图1至图3说明根据本发明的车辆格栅总成的工作过程。
如图1所示，在车辆发动机未启动或者启动时间不长时，冷却液温度低，诸如蜡的热膨胀材料6凝固并且体积较小。弹性材料5基本上未被压缩，推杆4伸入到弹性材料5的孔501中。弹簧13将可动板9(向上)推到壳体8的轴向一端的上方极限位置。即，可动板9保持在较高位置。格栅1会在连接构件2的带动下完全关闭。此时，由弹簧13支撑可动板9、移动壳7、膨胀材料6、弹性材料5和连接构件2。
如图2所示，当冷却液温度升高时(例如在发动机工作一段时间时)，温度升高的冷却液会流入冷却液容器12，诸如蜡的热膨胀材料6会在高温下融化。然后热膨胀材料6会膨胀到较大的体积。热膨胀材料6压缩弹性材料5，弹性材料5和孔501的轴向尺寸减小，同时弹性材料5的孔501缩小，从而将推杆4向轴向一侧(上侧)推出。由于推杆4固定于车身3而不能移动，弹性材料5将带动移动壳7和可动板9克服弹簧13的力向壳体8的轴向另一侧(向下)移动。从而可动板9移动到较低的位置，可动板9带动连接构件2驱动格栅1打开一定角度。
参照图3，当车辆速度增加时，冷却液温度更高，弹性材料5被进一步压缩将推杆4进一步推出，格栅1打开更大的角度。
同时，在车辆速度增加时，如箭头F3所示，吹向格栅1的风力增大。格栅1也会打开更大角度，连接构件2将可动板9压到更低的位置。
当冷却液温度降低和/或车辆速度降低时，弹簧13推动可动板9，使得格栅1朝向关闭方向移动。
如上所述，本发明提供了一种车辆格栅驱动装置及包括该车辆格栅驱动装置和可转动的格栅1的车辆格栅总成。该车辆格栅总成可以在车辆刚启动或低速时保持格栅关闭或开启较小角度，以减少风阻，使发动机工作在比较适宜的工作温度范围之内。在车辆高速行驶时，格栅开启较大角度，增加了发动机舱散热。本发明的车辆格栅总成可以提高车辆的燃油经济性。
本发明的车辆格栅驱动装置是可以自动调节格栅开度的机械装置，具有 高可靠性和低成本性。格栅的开度可以根据车辆的速度、发动机冷却液的温度进行调节，不需要外部电信号。因此，该车辆格栅驱动装置是一个自我调节的(被动式)装置，不需要外部控制系统，易于实现且可靠性高。
本发明的车辆格栅驱动装置和车辆格栅总成采用了模块化的设计理念，结构紧凑，易于应用。
当然，本发明不限于上述实施方式，本领域技术人员在本发明的教导下可以对本发明的上述实施方式做出各种改变和变型，而不脱离本发明的范围。
(1)图1至图3中仅示出了一片格栅1。然而，多片格栅可以彼此连动。或者可以由多个连接构件2分别驱动多片格栅。
(2)图1至图3所示的连接构件2呈单个杆件的形式，然而，本发明不限于此。连接构件2可以由多个构件连接而成，只要能够将可动板9的轴向(上下)移动转变成格栅1的开闭转动即可。
(3)弹簧13的数量可以为一个或多个。
(4)本发明的车辆格栅驱动装置采用了一些与车辆中常用的蜡式节温器类似的原理和结构。本发明的这些结构仅是示例性的。例如，CN105041448A、CN105971713A、CN205078330U、CN105134361A、CN105156197A、CN106150659A、CN102305125A、CN204140181U等公开了一些蜡式节温器。因此，本领域技术人员可以根据现有技术对本发明的对应结构做出各种改变和变型。
热膨胀材料6不限于蜡，弹性材料5也不限于橡胶。例如，为提高蜡的导热性，可以在蜡中添加金属颗粒。例如，CN105778997A公开了“一种导热性能稳定的蜡式节温器用介质的制备方法”。本领域技术人员可以根据本发明的教导适当选择和改变热膨胀材料6和弹性材料5的具体类型或构成。
上述专利的全部内容通过引用并入本文。
(5)冷却液容器12可以不必在整周上围绕移动壳7。只要冷却液容器12 与移动壳7实质上在较大面积接触从而将冷却液容器12内的冷却液的热量传递给移动壳7中的热膨胀材料6即可。
(6)本发明的一方面是通过移动壳7内的结构及推杆4带动可动板9移动，其实现方式不限于图1至图3所示的具体结构。例如，可以将移动壳7倒置地设置在可动板9的上方、固定到车身，推杆4的一端不是连接到车身而是连接到可动板9。从而在弹性材料5被压缩时，被压出的推杆4向下推动可动板9。
与该变型例相比，图1至图3的结构更加紧凑。
(7)替代弹簧13，或者附加地，可以设置用于将格栅1保持在图1所示的关闭状态的另一弹簧。
(8)连接板9不限于上述结构和形状，只要能够连接到移动壳7和连接构件2且承受弹簧13的压力即可。
(9)推杆4的一端可以直接固定于车身，推杆4的该一端也可以固定到壳体8。
(10)本发明不仅适用于以汽油或柴油为燃料的车辆，还适用于混合动力车辆、电动车辆等的其它类型的车辆。
