下面参考图1-图6描述本申请实施例的基于车载显示终端的交易系统1000。
如图1所示，该交易系统1000包括：车载显示终端200、整车服务平台300和移动终端400。
具体地，车载显示终端200用于获取车辆的信息，并根据车辆的信息生成随机二维码。移动终端400用于对随机二维码进行扫描，以建立移动终端与整车服务平台300之间的通信连接。整车服务平台300用于将服务信息发送至移动终端400进行显示，并接收用户根据服务信息通过移动终端400输入的购买指令，以进行购买交易，以及在购买交易成功后，将购买交易成功信息发送至移动终端400。
其中，移动终端400包括但不限于手机、电脑或PAD(平板电脑)等。整车服务平台300是针对整车服务开发的服务平台，其上可提供流量服务、救援服务、保养服务、精品服务等。移动终端400和整车服务平台30之间可通过4G/5G网络进行无线通信。
具体而言，车辆启动上电后，车载显示终端200按照预设的规则，根据车辆信息一次生成一个唯一的二维码，显示在车载显示终端200的显示界面(如，可进行触控操作的显示屏)上。进而用户通过移动终端400上安装的具有二维码扫描功能的APP(Application，应用程序)，如微信、支付宝等，扫描车载显示终端200上显示的二维码，进行购买交易。在购买交易成功后，整车服务平台300将购买交易成功信息发送至移动终端400，以对用户进行提醒。应当理解，该购买交易与该车辆服务相关，如保养服务、洗车服务等。可选 地，具有二维码扫描功能的APP具有支付功能，以便于用户快捷支付。
需要说明的是，由于车载显示终端200上显示的二维码是根据车辆的信息生成的，因此，在通过移动终端400扫描该二维码进行购买交易时，可默认购买的商品是服务于该车辆的，而无需用户另外选择，例如，购买4G流量，只需点击“购买”、“支付”即可，而无需输入车辆的身份信息(类似于手机号)，简化了购买操作流程。
由此，该交易系统通过车载显示终端根据车辆信息生成随机二维码，安全性强，通过移动终端扫描该随机二维码，建立移动终端与整车服务类平台之间连接，便于用户根据该平台的服务信息快速进行购买交易，提升了用户体验。
可选地，随机二维码仅在有效时间(如60s、3min、5min等)内有效。应当理解，如果通过移动终端400进行购买交易，则移动终端400需在有效时间内完成随机二维码的扫描，否则需要用户再次对车载显示终端进行操作，以重新根据车辆信息获取新的随机二维码。由于车载显示终端200上二维码的生成是随机的，即与车辆对应的二维码不是固定不变的，因此不易于被伪造和攻击，具有很强的安全性。
在该实施例中，车辆的信息可以包括车辆识别码VIN和车辆的当前位置，进而车载显示终端200具体用于根据车辆识别码、车辆的当前位置、车载显示终端200的ICCID(Integrate circuit card identity，集成电路卡识别码)、当前时间和设定的有效时间生成随机二维码。
其中，车辆识别码可以包含车辆的生产厂家、车型、生产年代、发动机代码及生产地址等信息。ICCID可相当于手机号码，是车载显示终端200中数据通信模块的卡号。
具体地，如图2所示，车辆启动上电后，车载显示终端200内的数据通信模块请求获取车辆的VIN、当前位置(如可通过全球定位系统GPS得到)、卡号ICCID、有效时间等，进而按照二维码生成的原理规则，生成随机二维码，并在车载显示终端200的显示界面显示，其中，出于安全性考虑，可采用60s等周期性有效时间机制。
在本申请的一个实施例中，如图3所示，整车服务平台300还与车载显示终端200进行通信，以在购买交易成功后将购买交易成功信息发送至车载显示终端200。
其中，车载显示终端200可通过4G/5G网络等与整车服务平台300进行无线通信。
进一步地，如图3所示，整车服务平台300还与4S服务店平台2000进行通信，以将用户购买的与4S服务店平台2000相关联的服务信息发送至4S服务店平台2000，以便于4S服务店提供购买交易的车辆服务，如流量服务、救援服务、保养服务、试驾服务等。
其中，4S服务店平台2000是针对车辆4S服务店开发的服务平台，其上设置有4S服务店可提供的服务，如保养服务、精品购买服务等。
需要说明的是，上述的无线通信网络并不限于4G/5G网络，只要是能够实现上述终端、 平台之间的通信即可。
应当理解，本申请的实施例中的车载显示终端200，作为车辆的车载多媒体，除具有用于实现上述交易的功能外，还具有导航、播放音乐/视频、收音机等功能。
在本申请的一个具体实施例中，如图4所示，整车启动上电后，车载显示终端200获取车辆识别码VIN、车辆的当前位置，进而根据VIN、车辆的当前位置、车载显示终端200的ICCID，当前时间和设定的有效时间按照预设规则生成随机二维码，并显示。移动终端400通过微信、支付宝等具备扫描支付功能的APP，在有效时间内扫描车载显示终端200上显示的二维码。扫描识别成功后，移动终端400与整车服务平台300进行通信，并在移动终端400的显示界面显示整车服务平台300可提供的车辆服务。用户通过对移动终端400进行所需服务的购买操作(如通过触控操作)，购买成功后整车服务平台300将购买成功信息发送至移动终端400，以便用户了解购买信息，还可将购买成功信息发送至车载显示终端200显示，以便用户了解购买结果，以及使车载显示终端在确认购买完成后进一步执行相应动作(如返回home界面、息屏等)，还可将购买成功信息发送至相应4S服务店平台2000，以便对应4S服务店及时提供相关服务。
在本申请的一个实施例中，整车服务平台300还将服务信息发送至车载显示终端200进行显示，以便用户根据服务信息输入下单指令。其中，车载显示终端200接收用户输入的下单指令，并将下单指令发送至整车服务平台300；整车服务平台300根据下单指令生成对应的支付信息，并将支付信息发送至移动终端400；移动终端400根据支付信息完成支付。
具体地，整车服务平台300在将服务信息发送至车载显示终端200后，用户可以通过车载显示终端200显示的服务信息购买服务，由此，在当车载显示终端200的显示屏比移动终端400的显示屏大时，用户能够在一个显示界面上浏览更多的服务商品，便于用户更快查找到所需服务商品。
进一步地，用户可通过车载显示终端200直接点击下单，而无需用户输入车辆的相关信息(如车辆位置、型号等)，进而在下单成功后，可直接通过移动终端进行支付，由此，使得交易更加便捷，且可以在一定程度上保证交易的准确性和安全性。
下面参考图5(a)、图5(b)描述本申请一个具体示例的通过上述交易系统购买车载显示终端200的4G流量的流程：
如图5(a)所示，整车上电后，如果车载显示终端200检测到车辆流量小于一定值如50M后，则弹出流量不足提醒，若用户不点击进入购买界面，则等到流量完全用完后车载显示终端200再提示用户；若用户点击进入购买界面，则车载显示终端200弹出根据车辆信息生产的二维码界面，并需在有效时间内使用移动终端400如智能手机中安装的微信、 支付宝等具有二维码扫描功能的APP进行扫描。
如图5(b)所示，智能手机扫描二维码后，显示由整车服务平台300提供的流量套餐选择界面，用户选择所需套餐后，进行相关支付购买。购买成功后，整车服务平台300会向手机发送短信、音频等提示信息提醒用户，同时车载显示终端200的显示界面会提示用户购买成功放心使用信息。需要说明的是，如果购买后流量仍小于50M，则不提醒用户流量不足，需待到下次整车上电再提示用户。
在本申请的一个实施例中，如图6所示，车载显示终端200可以是可旋转的，并可通过以执行机构100调节车载显示终端200进行旋转，例如，执行机构100可通过球铰接结构控制车载显示终端200转动。在该实施例中，可通过车载显示终端200的旋转角度控制车载显示终端200获取车辆信息，并根据车辆信息生成随机二维码，以便用户进行上述的车辆服务购买行为。
具体地，上述交易系统1000还包括转角传感器，其中，转角传感器用于检测车载显示终端200的旋转角度。例如，当用户需要购买车辆服务时，可以手动或自动旋转车载显示终端200至预设角度，所述预设角度为用户预先设置的车载显示终端的旋转角度，此时转角传感器检测到车载显示终端200的旋转角度达到预设角度如90°，则车载显示终端200根据该旋转角度达到预设角度的信号生成购买请求，进而根据该购买请求控制车载显示终端200获取车辆信息，并根据车辆信息生成随机二维码。
在本申请的一个示例中，如图6所示，执行机构100可用于转动车载显示终端200，比如使车载显示终端200在横屏或竖屏之间切换，或者使车载显示终端200转动到其他角度。该执行机构100可包括：安装单元、离合单元、驱动单元。其中，安装单元用于安装车载显示终端200；离合单元的第一接合部21与安装单元连接，离合单元的第二接合部23与第一接合部21相互锁止；驱动单元的输出端与第二接合部23连接。
具体地，参考图6，安装单元可以包括：安装支架11、转动盘13和安装轴15。其中，安装支架11与转动盘13相连，安装支架11用于安装车载显示终端200，转动盘13与安装轴15相连，安装轴15从转动盘13的内周沿向轴向延伸。安装轴15贯通离合单元、驱动单元，安装轴15用于将各个部件串成整体。
驱动单元可以包括：动力源31和减速器。动力源31输出的驱动力沿驱动单元-第二接合部23-第一接合部21-转动盘13-安装支架11-车载显示终端200传递，从而使车载显示终端200转动，实现车载显示终端200的转动或者横竖屏切换，其中，第一接合部21、转动盘13、安装支架11、显示终端200一起转动。驱动单元可与执行机构100中的底座50通过螺钉紧固，用以增大驱动单元的强度，提高其使用寿命。
参照图6，减速器包括主动蜗杆和从动直齿轮，动力源31的输出轴与减速器的主动蜗 杆可以通过联接器可拆卸地连接，主动蜗杆可枢转地安装于驱动单元的壳体，且主动蜗杆在自身的轴向上与驱动单元的壳体定位配合。进一步而言，主动蜗杆包括一级主动蜗杆32和二级主动蜗杆34，从动直齿轮包括一级从动直齿轮33和二级从动直齿轮35，一级主动蜗杆32与动力源31的输出轴连接，二级主动蜗杆34与一级从动直齿轮33同轴设置，二级主动蜗杆34与一级从动直齿轮33沿轴向间隔开设置。
其中，驱动单元的壳体包括：壳身37a、机壳后盖37c、机壳上盖37d、机壳前盖37f。动力源31、一级主动蜗杆32、一级从动直齿轮33、二级主动蜗杆34轮均安装于壳身37a，二级从动直齿轮35安装于机壳上盖37d，一级从动直齿轮33和二级主动蜗杆34固定在同一轴上。机壳后盖37c与壳身37a相连，以封闭壳身37a的后端，机壳上盖37d与壳身37a相连，机壳前盖37f与壳身37a相连，以封闭壳身37a的前端。机壳后盖37c、机壳上盖37d、机壳前盖37f与壳身37a之间可以通过卡接结构以及螺纹紧固件相连。机壳上盖37d具有套筒37e，二级从动直齿轮35套设在套筒37e外。
如图6所示，执行机构100还可包括弹性件40，弹性件40沿离合单元的轴向弹性抵压在安装单元与驱动单元之间，以使驱动单元、离合单元、安装单元顺次压紧，弹性件40的弹性预紧力(即轴向预紧力)用于使第二接合部23与第一接合部21接合。其中，可使用轴向限位件42形成挡墙压紧弹性件40，以有效保证系统的防抖、抗振性能。
综上，根据本申请上述实施例的基于车载显示终端的交易系统，通过可旋转的车载显示终端根据车辆信息生成随机二维码，安全性强，通过移动终端扫描该随机二维码，以在移动终端显示整车服务类平台提供的交易服务，便于用户快速进行购买交易，提升了用户体验，通过整车服务类平台将购买成功信息反馈至车载显示终端，便于车载显示终端确认购买行为完成，通过整车服务类平台将购买成功信息发送至4S服务店平台，便于4S服务店及时提供相关服务。
