汽车升降尾翼及系统
技术领域
本发明涉及汽车尾翼技术领域，特别涉及一种汽车升降尾翼及系统。

下面参照附图详细描述本发明实施例的汽车升降尾翼。
如图1至图4所示，根据本发明实施例的汽车升降尾翼，用于安装在汽车尾部，减小汽车尾部的升力，其包括尾翼本体200和升降装置100；其中，所述尾翼本体200的底部开设有一收容槽201，较佳地，尾翼本体200采用碳纤维或ABS材料制成，其可以设计成各种尾翼形状，本发明不对其形状做特别限制；所述升降装置100设置在所述收容槽201内，其包括驱动组件10和安装件20，所述安装件20用于固定安装在汽车的尾部，所述驱动组件10固定在所述收容槽201内，并与所述安装件20连接，用于驱动所述尾翼本体200相对所述安装件20上升或下降。
根据本实施例的汽车升降尾翼，通过将安装件20固定在汽车尾部上，如此可根据不同的路况或车速来控制驱动组件10驱动尾翼本体200的上升或下降，即调节尾翼本体200相对汽车尾部的高度，以此来调节气流对尾翼本体200所产生的负升力；而且由于升降装置100设置在尾翼本体200内，使得在进行安装尾翼时，无需对汽车的后盖进行过多的改装，特别适用于出厂无尾翼车辆的加装。
具体地，所述驱动组件10包括驱动电机11、丝杆12、第一丝母14、第一连动杆141、第二丝母15、以及第二连动杆151，所述驱动电机11固定在所述收容槽201内；所述 丝杆12具有正向螺纹段121和反向螺纹段122，其设置于所述收容槽201内，并由所述驱动电机11驱动其转动；所述第一丝母14套设在所述正向螺纹段121上；第一连动杆141的一端铰接在所述第一丝母14上，另一端铰接在所述安装件20上；所述第二丝母15套设在所述反向螺纹段122上；所述第二连动杆151的一端铰接在所述第二丝母15上，另一端铰接在所述安装件20上。其中，第一连动杆141和第二连动杆151的数量分别为两个，两个第一连动杆141的一端分别铰接在第一丝母14的两侧上，两个第二连动杆151的一端分别铰接在第二丝母15的两侧上，且两个第一连动杆141相互平行，两个第二连动杆151相互平行。
示例性的，当驱动电机11驱动丝杆12正向转动时，第一丝母14和第二丝母15分别相互靠近，而第一连动杆141与第一丝母14铰接的一端绕另一端铰接轴向第一丝母14靠近方向旋转，第二连动杆151与第二丝母15铰接的一端绕另一端铰接轴向第二丝母15靠近方向旋转，从而带动尾翼本体200向下运动至驱动组件10完全收容在收容槽201内，可使尾翼本体200与汽车尾部之间形成接近贴合状态，此时尾翼本体200所产生的负升力大大减少(如图1和图3所示)。同理，当驱动电机11驱动丝杆12反向转动时，第一连动杆141和第二连动杆151与丝母的铰接端向上旋转，从而带动尾翼本体200向上运动，使尾翼本体200与汽车尾部之间形成有较宽的间隙，此时尾翼本体200所产生的负升力大大增加，提高汽车行驶时对地面的附着力。
进一步地，所述驱动组件10还包括有一固定板13，所述固定板13固定安装在所述收容槽201的顶壁上，所述驱动电机11固定在所述固定板13底面的中间位置，所述固定板13底部的两端分别设置有用于安装所述丝杆12的支撑板131。也就是说，升降装置100的各个部件可先安装在一起形成一个整体，然后在将整体的升降装置100通过固定板13固定安装在尾翼本体200的收容槽201内，使得无需对尾翼本体200做过多的结构设计，生产成本低且结构牢固可靠，组装更加方便。
在本实施例中，所述驱动电机11为双头电机，所述丝杆12的两端分别转动安装在两个所述支撑板131上，所述正向螺纹段121和反向螺纹段122相对于所述驱动电机11对称。如此，使升降装置100的整体结构更加紧凑，在具体应用时，驱动电机11通过一固定框18安装在固定板13的中部上，该固定框18的截面为U型结构，从而包裹在驱动电机11的侧壁上，对驱动电机11起到保护固定作用。
在其他实施例中，驱动电机11可以采用单头电机，即采用反向设置的第一驱动电机和第二驱动电机，所述丝杆12也包括第一丝杆和第二丝杆，所述正向螺纹段121设置在所 述第一丝杆上，所述反向螺纹段122设置在所述第二丝杆上，所述第一丝杆安装在所述第一驱动电机和一个所述支撑板131之间，所述第二丝杆安装在所述第二驱动电机和另一个所述支撑板131之间。
在本发明的一些实施例中，所述驱动组件10还包括第三丝母16、第三连动杆161、第四丝母17以及第四连动杆171，所述第三丝母16套设在所述正向螺纹段121上，并通过第一连接杆162与所述第一丝母14固定连接；所述第三连动杆161的一端铰接在所述第三丝母16上，另一端铰接在所述安装件20上；所述第四丝母17套设在所述反向螺纹段122上，并通过第二连接杆172与所述第四丝母17固定连接；所述第四连动杆171的一端铰接在所述第四丝母17上，另一端铰接在所述安装件20上。需要理解的是，第一连动杆141和第三连动杆161分别位于第一连接杆162的两侧，第二连动杆151和第四连动杆171分别位于第二连接杆172的两侧，如此在尾翼本体200下降时，能使驱动组件10最大限度的收合，减少驱动组件10收合时的厚度，使驱动组件10可完全收容于尾翼本体200的收容槽201内。
进一步地，所述安装件20包括第一安装板21、第二安装板22以及第三安装板23，所述第一连动杆141和第三连动杆161的所述另一端分别铰接在所述第一安装板21上；所述第二连动杆151和第四连动杆171的所述另一端分别铰接在所述第二安装板22上；所述第一安装板21和第二安装板22分别固定在所述第三安装板23上的两端，所述第三安装板23用于固定安装在汽车的尾部上。
本发明还提出一种升降尾翼系统，该升降尾翼系统包括控制器300和汽车升降尾翼，该汽车升降尾翼的具体结构参照上述实施例，由于本升降尾翼系统采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
其中，所述控制器300包括主控模块301、CAN通信模块302、OBD接头303、升降驱动模块304以及为上述各模块进行供电的供电模块305，所述升降驱动模块304与所述汽车升降尾翼的升降装置100连接，所述主控模块301分别与所述CAN通信模块302和升降驱动模块304连接，所述OBD接头303与所述CAN通信模块302连接，并用于插接到所述汽车上的OBD接口，以获取所述汽车的车速信息，所述主控模块301根据所述车速信息控制所述升降驱动模块304来驱动所述升降装置100。
具体地，所述升降装置100的驱动组件10根据所述汽车的车速控制所述尾翼本体200的上升或下降；当所述汽车的车速大于V1时，所述驱动组件10驱动所述尾翼本体200 上升；当所述汽车的车速小于V2时，所述驱动组件10驱动所述尾翼本体200下降，且所述V1大于V2。示例性的，所述汽车的车速大于20km/h时，所述驱动组件10驱动所述尾翼本体200上升；当所述汽车的车速小于10km/h时，所述驱动组件10驱动所述尾翼本体200下降。
进一步地，本实施例的控制器300还包括蓝牙模块306，通过所述蓝牙模块306可与用户的智能移动终端400建立蓝牙通信连接，以便于通过所述智能移动终端400手动控制尾翼本体200的升降或修改上述V1和V2的参数；例如，用户可根据实际路况，将V1的参数修改为50km/h，而V2的参数不变。具体实施时，智能移动终端400包括但不限于智能手机、平板电脑、掌上智能终端、便携式计算机。
更进一步地，本实施例的控制器300还包括GPS定位模块307以及网络通信模块308，所述GPS定位模块307用于对所述汽车进行实时定位和跟踪，并将获得的GPS坐标数据经由所述网络通信模块308通过3G或4G移动通信网络发送至云服务器500，所述智能移动终端400可与所述云服务器500通信连接，以获取所述GPS坐标数据。如此，通过智能移动终端400可从云服务器500上获得汽车的位置信息以及行车轨迹，从而起到对车辆的监控和防盗。
