具体实施方式
现在将参照附图来详细描述本发明的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本发明的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
一种通过无线网络控制的汽车顶棚，如图1所示，包括顶棚、设置在车身内的主控制器1、至少一个分控制器2和设置于所述顶棚内的至少一个用电装置，主控制器1通过无线网络与分控制器2进行数据与信号传输，分控制器2与至少一个用电装置连接。
汽车顶棚是设置在车厢顶部的，与前、后窗框及支柱连接的盖板，起到遮风挡雨，隔热保温，以及降低车厢内噪音的作用。同时，汽车顶棚的形状设计能使汽车获得最好的视觉感和最小的空气阻力。由于汽车顶棚的刚度对汽车碰撞时的作用不大，因此汽车顶棚上可以设置天窗，达到通风换气的作用。另外，汽车顶棚还设置其他用电装置，并与车身主线束进行连接，以获得控制信号及电源。
本发明的主控制器1通过无线网络与各个分控制器2进行数据与信号传输，主控制器1不需要使用线束3与各个分控制器2连接，节省了线束3的使用量，也降低了各个用电装置的安装和维修工时，减少了整个汽车顶棚系统的成本。
主控制器1中可以包括计算单元，可以包括中央处理器(CPU)、微控制单元(MCU)、数字信号处理器(DSP)、可编辑逻辑控制器(PLC)、现场可编程逻辑门阵列(FPGA)等。同时仪表盘上会设置人机接口，驾驶员能够通过人机接口，对主控制器1进行操作，计算单元将驾驶员的操作转化为控制信号，通过无线网络发送给分控制器2，分控制器2也会把汽车顶棚内的用电装置的状态信息，通过无线网络发送给主控制器1。无线网络可以是基于蓝牙、wifi、紫蜂(ZigBee)、物联网(IOT)、红外、无线家庭数字接口(WDHI)等无线通信技术。
在一种实施方式中，分控制器2也可以设置计算单元，可以包括中央处理器(CPU)、微控制单元(MCU)、数字信号处理器(DSP)、可编辑逻辑控制器(PLC)、现场可编程逻辑门阵列(FPGA)等。分控制器2与汽车顶棚内的用电装置通过连接线束3连接，能够更加稳定快速的将控制信号传递到用电装置，汽车顶棚内部空间较小，即使使用连接线束3连接，连接线束3分支的长度也较短，不会增加太多连接线束3重量。
另外分控制器2本身有计算和控制功能，汽车顶棚内的用电装置的部分功能的状态监控和命令信息，可以不用通过无线网络传输给主控制器1做计算和判断，可以直接由分控制器2进行计算和判断，不仅降低了主控制器1的计算负荷，同时也节省了信号传递的过程，能够对用电装置的控制更加快速，例如汽车顶棚的车顶天窗自动关闭等。
在一种实施方式中，如图1所示，汽车顶棚中的用电装置，包括车顶天窗模块41、顶棚灯模块42、后视镜显示模块43、天线模块44和音响模块45中的一者或多者。
车顶天窗模块41安装于车顶，能够有效地使车内空气流通，增加新鲜空气的进入，同时车顶天窗模块41也可以开阔视野以及移动摄影摄像的拍摄需求。车顶天窗模块41可大致分为：外滑式、内藏式、内藏外翻式、全景式和窗帘式等。主要安装于商用SUV、轿车等车型上。
顶棚灯模块42包括汽车车顶上安装的灯，灯罩上用文字或用颜色表示车辆的用途，主要是出租车的车顶灯；还包括安装在顶棚扣板112上的灯。轿车一般仅设有一只顶棚灯，除用作室内照明外，还可兼起监视车门是否可靠关闭的作用；在监视车门状态下，只要还有车门没有可靠关闭，顶棚灯就发亮。汽车顶棚灯的作用于车内乘客照明，且不能致使驾驶员炫目。现在车辆的顶棚灯也可用门控开关控制，车内打开就会接通开关，顶棚灯亮起，车门关闭则断开开关，顶棚灯熄灭。
后视镜显示模块43又叫车载后视镜显示器，是指安装在汽车后视镜上的显示器。使后视镜不再是简单的镜子，而是能够显示倒车影像和雷达信息的显示器，可以同时具备行车记录仪、导航系统和语音控制等多种功能。后视镜显示模块43增加了驾驶的娱乐性，也会将多种功能集一身，节省车内空间。
天线模块44是拦截发射台发射的高频电波并传输给汽车收音机、车载电话或无线电导航设备的接收机，以对载波解调的装置。由于车载媒体使用数量增加，预计今后使用量将逐渐增多，主要用于AM/FM收音机、GPS、电话、卫星收音机、ETC等。
音响模块45，在汽车顶棚的预定位置，还可以设置音响模块4553，也就是扬声器，通过仪表盘上的主机和功放发送音频信号，由主控制器1通过无线网络传输给分控制器2，再由分控制器2通过连接线束3传递给扬声器，能够在汽车内部形成环绕立体声，使车内的人员能够享受到稳定和完善的音质，减轻驾驶员和乘员旅行中的枯燥感。
汽车顶棚内还可以设置很多其他功能，而这些功能大部分都是通过电动部件驱动实现的，因此汽车顶棚内连接线束3用量或越来越多，使用无线网络连接汽车顶棚和主控制器1，可以减少连接线束3的用量，方便汽车顶棚的维修和更换。分控制器2的设 置，也会使汽车顶棚更加智能，并能够满足车联网的大部分需求。
在一种实施方式中，如图2所示，主控制器1包括无线发射单元71，分控制器2包括无线接收单元72，主控制器1的输出端与无线发射单元71连接并通过无线网络发送控制信号，分控制器2的输入端与无线接收单元72连接并接收控制信号。
无线发射单元71，是指能将主控制器1的控制信号，转化为无线传输信号，再通过无线发射天线发送出去，例如F05R是一款小体积低电压、微功率无线发射模块。采用SMT工艺，声表稳频，性能稳定，特别适合电池9供电的小体积无线遥控，数据传输产品使用。无线接收单元72，一般分为超再生和超外差接收模块两种类型，按照是否有编解码还可分为无线接收头(不带解码，输出脉冲信号)、无线接收板(带解码芯片，输出TTL电平信号)。主控制器1的控制信号，经过无线发射单元71发送后，再由无线接收单元72接收，并转化为控制信号传递给分控制器2，并由分控制器2对相应的用电装置进行控制。
在一种实施方式中，如图2所示，主控制器1包括无线接收单元72，分控制器2包括无线发射单元71，分控制器2的输出端与无线发射单元71连接并通过无线网络发送状态信息，主控制器1的输入端与无线接收单元72连接并接收状态信息。
当汽车顶棚内的用电装置自身的运行状态发生变化时，需要将状态信息反馈给主控制器1，此时就需要分控制器2具备无线发射单元71，分控制器2可以将用电装置的状态信息传递给无线发射单元71，再由无线发射单元71通过无线发射天线发送出去。主控制器1具备无线接收单元72，主控制器1的无线接收单元72接收到无线网络发送的信号后，转化为用电装置的状态信息，并传递给汽车的人机接口，使驾驶人员能够随时了解汽车顶棚内的用电装置的工作状态，能够及时的做出相应的反馈。
在一种实施方式中，如图2所示，无线发射单元71还包括加密模块81，主控制器1和分控制器2的输出端通过加密模块81与无线发射单元71连接，加密模块81将控制信号或状态信息加密；无线接收单元72包括解密模块82，主控制器1和分控制器2的输入端通过解密模块82与无线接收单元72连接，解密模块82将接收到的控制信号或状态信息解密。
随着车辆信息化的进展越来越大，车载网络在大部分汽车上都实现了设置和使用，不同车辆之间的信号交涉也相应的增加，为了使不同车辆之间的无线控制信号不会误操作其他车辆，每个车辆的信号发射和接收都会有相应的加密和解密程序，同时也是为了防止黑客对车辆的入侵，使外界信号不能接入车辆的信息传递网络。加密模块81是通过 内部的编码器，将控制信号或状态信息通过一定的规则重新编码，也就是密钥，然后再将编码后的信息通过无线传输发送出去，这样即使有其他车辆接收到无线信息，由于没有对应的密钥，也无法识别相应的信息，同时，密钥也会自带识别码，其他车辆如果接收信息的识别码与自身的识别码不一致，就不会对相应的信息进行识别。只有识别码对应上的信息接收装置，也就是相应的解密模块82，才会对信息使用对应的规则进行解密，并将解密后的信息传递给对应的主控制器1或分控制器2。
在一种实施方式中，如图2所示，还包括钥匙5，钥匙5内设置无线发射单元71，无线发射单元71通过无线网络连接分控制器2。
现有汽车都会配备几把钥匙5，除了用来打开和锁定车门或后备箱，还可以打开或关闭车顶天窗。目前的汽车钥匙5都有遥控功能，内部设置无线发射单元71，能够通过无线网络，对汽车顶棚内的用电装置进行控制。
汽车钥匙5的控制信号，可以通过无线网络连接主控制器1，由主控制器1给汽车顶棚内的用电装置下发控制信号，也可以通过无线网络连接分控制器2，由分控制器2直接控制汽车顶棚内的用电装置动作，实现相应的功能，可以减少主控制器1的计算量。
在一种实施方式中，当钥匙5和主控制器1同时通过无线网络发送控制信号时，分控制器2以主控制器1的控制信号为准。
在实际使用过程中，存在驾驶员在汽车内部通过主控制器1下达控制信号，同时车外部的另外的人员拿着钥匙5发送控制信号，当两个控制信号执行的命令相反时，会导致汽车顶棚内的用电装置无法动作或出现动作卡顿，因此当钥匙5和主控制器1同时通过无线网络发送控制信号时，分控制器2以主控制器1的控制信号为准，以驾驶员的意愿为主，保证了汽车操作的安全性。
在一种实施方式中，如图2所示，还包括移动控制终端6，移动控制终端6通过无线网络连接分控制器2，分控制器2通过无线网络将状态信息反馈给移动控制终端6。
移动控制终端6包括手机、平板或移动笔记本电脑等，移动控制终端6能够通过wifi、蓝牙、4G网络或者5G网络连接到汽车的无线网络中，并与分控制器2的无线发射单元71和无线接收单元72无线连接，能够接收到分控制器2发送的状态信息，即使驾驶人员没有在车内，也可以通过移动控制终端6，了解汽车顶棚内的用电装置状态信息，从而及时处理一些异常情况。例如下雨时可以在移动控制终端6上查看车顶天窗是否关闭。移动控制终端6也可以通过安装的软件给汽车顶棚内的用电装置传递控制信 号，控制部分功能，使驾驶人员不用到车内就能实现对汽车顶棚内的用电装置的操作。
在一种实施方式中，当移动控制终端6和主控制器1同时发送控制信号时，分控制器2以主控制器1的控制信号为准。
当移动控制终端6和主控制器1同时发送控制信号时，也代表车内驾驶室中有人在操作，分控制器2则以主控制器1发送的控制信号为准，避免由于移动控制终端6的误操作，造成汽车非预期的动作。
在一种实施方式中，如图2所示，还包括电池9，电池9可拆卸的安装在顶棚内，电池9通过连接线束3与用电装置和分控制器2电连接，并给电负载装置和分控制器2提供电能。
汽车顶棚设置在车身的顶部，汽车顶棚内的用电装置都需要电能才能驱动，如果通过汽车发电机或者电瓶进行供电，则车身与汽车顶棚之间还需要引出很多电源线连接，造成安装的工时增加，因此，汽车顶棚内的用电装置就近设置了电池9，并且可拆卸的安装在汽车顶棚内，以方便电池9的更换。电池9与用电装置或分控制器2设在在一起，之间通过线束3连接并提供电能。
另外，汽车顶棚内的车顶天窗模块41、顶棚灯模块42、后视镜显示模块43、天线模块44和音响模块45等，在汽车熄火后有可能还需要工作，例如车顶天窗模块41，在汽车熄火后也要能够开启和关闭车顶天窗，方便车内通风，因此需要在汽车顶棚内中设置单独的电池9，使其在汽车熄火后，也能对汽车顶棚内的用电装置进行控制，并能够通过无线网络，发送到驾驶人员的移动控制终端6上。
在一实施例中，图3为本发明汽车顶棚的再一种结构框图。
在一种实施方式中，如图4所示，顶棚内设置电池安装腔体93，电池安装腔体93内和电池9设置卡接机构94，能使电池9卡接在电池安装腔体93内；顶棚外侧还设置解锁按钮95，解锁按钮95能够解锁卡接机构94，使电池9能够从电池安装腔体93内取出。
汽车顶棚内的用电装置就近设置了电池9，在顶棚内部，就需要设置电池安装腔体93，使电池9能够固定在电池安装腔体93内，为汽车顶棚内的用电装置进行供电。为了防止出现因电池9晃动等导致的供电不稳定问题，在电池安装腔体93内和电池9上设置卡接机构94，能使电池9卡接在电池安装腔体93内。如图4所示，卡接机构94包括设置在电池9上的卡爪，卡爪通过铰链固定在电池9侧边，并能够绕铰链转动，卡爪与电池9之间还设置弹簧，能够使卡爪保持在远离电池9的位置。在电池安装腔体93内的侧 边设置卡槽，当电池9插入到电池安装腔体93内时，卡爪与卡槽卡接，使电池9能够稳定的固定在电池安装腔体93内。
由于电池9的电量在使用中消耗，到一定时间需要更换汽车顶棚内的电池9，需要能够方便的将电池9从电池安装腔体93内取出，在顶棚内侧设置解锁按钮95，解锁按钮95可以是直接设置在电池安装腔体93侧边，通过按压卡接机构94的卡爪，使其脱离卡槽，电池9就能够从电池安装腔体93内取出。解锁按钮95也可以是设置在顶棚内侧的按键，按键连接顶出装置，按键和顶出装置通过线束3连接，按压按键使顶出装置动作，顶出装置可以按压卡接机构94的卡爪，使其脱离卡槽，电池9就能够从电池安装腔体93内取出。
在一种实施方式中，如图4所示，电池9上设置电极触点96，电池安装腔体93内对应位置设置电极弹片97，当电池9卡接在电池安装腔体93内时，电极触点96接触电极弹片97并电连接。
为了使电池9插入到电池安装腔体93内后，电池9的电源就能与汽车顶棚内的线束3连接上，电池9底部设置电极触点96，分别为正极触点和负极触点，电池安装腔体93内对应的位置设置电极弹片97，分别为正极弹片和负极弹片，由弹性金属片制成，具有一定的弹性，能够在振动条件下也能稳固的连接电极触点96。电池9完全插入到电池安装腔体93内后，电极触点96与电极弹片97接触并实现电连接，通过与电极弹片97连接的线束3，为汽车顶棚内的用电装置和分控制器2供电。
在一种实施方式中，车身内还设置电池充电装置(图中未示出)，电池9放置在电池充电装置内并进行充电。
当汽车顶棚内的电池9的剩余电量低于报警值时，不一定有时间进行电池9的充电，因此可以在汽车的后备箱内或其他位置设置电池充电装置，在汽车运行状态下，可以通过发电机，为放置在电池充电装置内的电池9进行充电，当车门内的电池9的剩余电量低于报警值时，可以及时将电池充电装置内已经充电完成的备用电池9拿出来更换上，不会耽误车门内用电装置或分控制器2的使用。
在一种实施方式中，如图5所示，电池9上设置无线充电线圈92，无线充电线圈92与电极触点96电连接。
无线受电线圈91可设置于电池9侧面并与电池9的电极连接，以用于对电池9进行无线充电。其中，无线受电线圈91可以基于电磁感应耦合或磁共振耦合等无线充电方式，对电池9进行无线充电。
电磁感应耦合是指当无线充电线圈92靠近无线受电线圈91时，无线充电线圈92发射的能量信号以电磁感应方式耦合至无线受电线圈91，并提供给电池9。
磁共振耦合是指无线充电线圈92内设有与无线充电线圈92串联的送电侧谐振电容，从而形成送电侧LC谐振电路；无线受电线圈91内设置有与无线受电线圈91串联的受电侧谐振电容，从而形成受电侧LC谐振电路；并且送电侧LC谐振电路和受电侧LC谐振电路具有相同的谐振频率。当无线充电线圈92通电时，送电侧LC谐振电路会产生一个高频振动磁场；在这个高频振动磁场中任意位置处任意时刻的磁场和电场之间呈正交关系，并且在相位上相差1/2π,而且磁场强度远高于电场强度，这个空间电磁场它可以储存能量，但合成的电磁波功率流密度为零，不会传输任何能量，也就是说这个场不会向外辐射，也不会向内损耗。当无线充电线圈92靠近无线受电线时，无线受电线圈91会落入高频振动磁场的范围，由于受电侧LC谐振电路具有与送电侧LC谐振电路相同的谐振频率，受电侧LC谐振电路将产生同频磁场的谐振，使得能量从无线充电线圈92以磁共振形式耦合至无线受电线圈91，并提供给电池9。
在一种实施方式中，如图5-图6所示，顶棚外侧设置太阳能电池板10，太阳能电池板10通过铰接结构101与顶棚连接，太阳能电池板10的充电线缆与电极触点96电连接。
由于配套设施的不完善，或者车辆处于较偏远地区，无法及时对电池9进行充电，可能会导致汽车电器无法打开，甚至汽车无法发动的情况。因此对电池9的充电应该有多种方式。本发明在顶棚扣板112外侧，设置了太阳能电池板10，太阳能电池板10是通过吸收太阳光，将太阳辐射能通过光电效应或者光化学效应直接或间接转换成电能的装置。太阳能电池板10通过铰接结构101与顶棚钣金111连接，为了防止太阳能电池板10因为振动从顶棚钣金111中脱落，也可以在太阳能电池板10的其他位置设置安装部，通过卡接或螺接等方式，将太阳能电池板10稳定的固定在汽车顶棚的内部，同时为了减小太阳能电池板10与顶棚钣金111之间干涉产生异响，在安装部可以防止减震垫，能够吸收振动，也能避免太阳能电池板10损坏。
为了降低汽车顶棚的重量，降低刚性太阳能电池板10的振动异响，太阳能电池板10可以采用柔性薄膜太阳能电池9，柔性薄膜太阳能电池9不需要采用玻璃背板和盖板，重量比双层玻璃的太阳能电池9片组件轻80％，采用PVC背板和ETFE薄膜盖板的柔性电池9片甚至可以任意弯曲，方便携带。
在一种实施方式中，如图5-图6所示，顶棚包括顶棚钣金111和顶棚扣板112，分 控制器设置在顶棚钣金111与顶棚扣板112之间，铰接结构101将太阳能电池板10从顶棚扣板112外侧翻转到顶棚钣金111外侧，并给电池9充电。
当电池9电量不足，又无法及时对电池9进行充电时，可以将车顶天窗打开，将太阳能电池板10从汽车顶棚的内部翻转到汽车顶棚的外侧，并由铰接结构101对太阳能电池板10进行固定。太阳能电池板10的充电线缆与电池9的电极连接，会将太阳能转化为电能，为电池9进行充电。
在一种实施方式中，太阳能电池板10能够折叠和打开。太阳能电池板10的面积越大，对太阳能的转化效率越高，充电越快，但是汽车顶棚的面积不大，对应面积大小的太阳能电池板10需要很长时间才能将电池9的电量补足，因此可以将太阳能电池板10设置为可折叠和打开的，不用的时候折叠成小面积，放置在汽车顶棚的内部，需要使用时将其打开，扩展为大面积的太阳能电池板10，从而提高充电效率，节省充电时间。
刚性的太阳能电池板10可以采用叠放的方式，由多片太阳能电池板10相互叠加，之间使用连杆机构连接，需要的时候将多片太阳能电池板10展开形成一个平面。柔性薄膜太阳能电池9则可以卷曲起来，放置在汽车顶棚的内部，使用时将其展开，为电池9进行充电。
在一种实施方式中，如图7-图8所示，顶棚扣板112和顶棚钣金111上设置天窗开口12，顶棚扣板112内侧，顶棚钣金111外侧设置经过天窗开口12的两条U型轨道102，U型轨道102上设置太阳能电池板10，太阳能电池板10在U型轨道102中滑动，在顶棚扣板112内侧和顶棚钣金111外侧往复移动。
太阳能电池板10设置在汽车顶棚外，可以充分接收太阳光，并转化为电能存储到电池9中，但是太阳能电池板10在汽车顶棚外，在汽车运行过程中会增大汽车的风阻，使汽车油耗增加，因此太阳能电池板10在不用的时候，最好隐藏在汽车内部。
在顶棚扣板112和顶棚钣金111上设置天窗开口12，车顶天窗设置在天窗开口12中，顶棚扣板112内侧，顶棚钣金111外侧设置经过天窗开口12的两条U型轨道102，如图7-图8所示，U型轨道102一侧设置在汽车顶棚外侧，另一侧设置在顶棚扣板112和顶棚钣金111之间，通过天窗开口12的U型轨道102在车顶天窗关闭时，可以完全由车顶天窗的密封边进行密封，不会导致雨水进入到车内。当汽车在行驶状态时，如图8所示，太阳能电池板10位于U型轨道102的下方，处于顶棚扣板112和顶棚钣金111之间，不会影响汽车的行驶。当电池9电量不足需要充电时，可以将车顶天窗打开，太阳能电池板10在电机的驱动下，沿着两条U型轨道102，从U型轨道102的下方，移动到 U型轨道102的上方，位于汽车顶棚外侧，此时太阳能电池板10接收太阳光，并转化为电能存储到电池9中。
在一实施例中，图9为本发明汽车顶棚的太阳能电池板的第四种结构示意图。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
