请一并参阅图1及图2，现对本申请提供的行车记录仪进行说明。所述行车记录仪，包括主机1、从机2、以及电连接主机1和从机2的传输线5。主机1用于拍摄和记录车外的情景，且朝向车外；从机2用于拍摄和记录车内的情景，且朝向车内。主机1和从机2相互分离，便于调整主机1和从机2的相对位置，以适应不同的车型，获取最佳的拍摄角度。传输线5用于实现主机1和从机2之间的数据传输及信号传输，传输线5可包括主机1的输出线及从机2的输出线。传输线5的外周包裹有线卡6，线卡6用于整理传输线5，避免安装主机1及从机2后的传输线5拖沓，从而避免传输线5影响视线。主机1和从机2均固定于挡风玻璃3上，线卡6卡设于挡风玻璃3和车内后视镜4之间，可进一步减小线卡6对开车视线的影响。具体地，假设车内后视镜4具有镜子的一侧为前侧，另一侧为后侧。主机1设于车内后视镜4的后侧，朝向车外，从机2设于车内后视镜4的前侧，朝向车内，便于将线卡6卡设于挡风玻璃3和车内后视镜4之间，减小线卡6对车内后视镜4视线及挡风玻璃3视线的影响。
本申请提供的行车记录仪，与现有技术相比，本申请行车记录仪通过设置用于拍摄车外情景的主机1、用于拍摄车内情景的从机2，且主机1和从机2相互分离，使得主机1和从机2的相对位置可调，适用于不同的车型。电连接主机1和从机2的传输线5的外周包裹有线卡6，使得传输线5可收纳于线卡6内，避免了传输线5的拖沓而影响开车视线，且线卡6卡设于挡风玻璃3和车内后视镜4之间，减少了对车内后视镜4及挡风玻璃3的遮挡，从而减小了该行车记录仪对开车视线的影响。
进一步地，请参阅图4及图5，作为本申请提供的行车记录仪的一种具体实施方式，线卡6包括可拆卸连接的线卡座62和线卡盖61，线卡座62和线卡盖61的可拆卸连接便于对传输线5进行检修，也便于分别拆卸主机1及从机2，还便于调整线卡座62及线卡盖61的长度，调整主机1和从机2的相对位置，使其适用于不同的车型。线卡座62上凸设有卡扣6211，线卡盖61上设有与卡扣6211卡接的卡孔6110，通过卡扣6211和卡孔6110实现线卡座62和线卡盖61的可拆卸连接，拆装线卡6时，无需使用工具，且拆装步骤简单。
进一步地，请继续参阅图4至图6，作为本申请提供的行车记录仪的一种具体实施方式，线卡座62包括多个依次连接的卡座单元621，相邻两个卡座单元621之间设有第一连接臂622，卡扣6211设于卡座单元621上。线卡盖61包括多个依次连接的卡盖单元611，相邻两个卡盖单元611之间设有第二连接臂612，卡孔6110设于卡盖单元611上。第一连接臂622用于连接相邻的两个卡座单元621，相邻两个卡座单元621可通过折断第一连接臂622实现两个卡座单元621的相互分离，从而可根据主机1和从机2之间的距离选择线卡座62的长度。第二连接臂612用于连接相邻的两个卡盖单元611，相邻两个卡盖单元611可通过折断第二连接臂612实现两个卡盖单元611的相互分离，从而可根据主机1和从机2之间的距离选择线卡盖61的长度。所以线卡6的整体长度可调，主机1和从机2的相对位置可调，使该行车记录仪可适用于私家车、出租车、公交车等不同车型的车。
进一步地，请参阅图3至图5，作为本申请提供的行车记录仪的一种具体实施方式，主机1包括主机外壳11、镜头组件12以及紧固件13，主机外壳11上开设有供紧固件13穿过的导向槽1110。具体地，主机外壳11包括主机下盖111、以及盖设于主机下盖111的主机上盖112，导向槽1110设于主机下盖111上。主机上盖112和主机下盖111共同形成用于容置镜头组件12的镜头腔110，镜头腔110优选为圆柱形。镜头组件12设于主机外壳11内，且与主机外壳11转动连接。紧固件13与镜头组件12螺纹连接，紧固件13用于使镜头组件12转动，便于调节镜头组件12的拍摄角度。具体地，紧固件13包括相互连接的头部131和螺纹杆132。螺纹杆132与镜头组件12螺纹连接，用于驱动镜头组件12转动，镜头组件12上开设有与螺纹杆132的外螺纹螺纹连接的螺纹孔1230。螺纹杆132穿设于导向槽1110中且螺纹连接于镜头组件12时，头部131与主机外壳11相抵接。具体地，紧固件13与主机下盖111抵接锁紧。紧固件13在导向槽1110内移动以调节镜头组件12的拍摄角度，拍摄角度确定后，将紧固件13与主机外壳11抵接锁紧，从而使镜头组件12和主机外壳11相互固定，进行稳定拍摄。紧固件13的螺纹杆132穿过导向槽1110与镜头组件12螺纹连接，调节镜头组件12的角度时，紧固件13和主机外壳11相互松脱，镜头组件12可在紧固件13的带动下转动，使用紧固件13调节镜头角度较方便；进行拍摄时，将紧固件13拧紧至其头部131与主机外壳11相抵接锁紧，该种锁紧方式操作简单。
进一步地，作为本申请提供的行车记录仪的一种具体实施方式，镜头组件12的转动角度小于或者等于80º。镜头组件12的转动角度与导向槽1110的形状及大小有关，其调节角度较大时，导向槽1110也相对较长，供镜头组件12伸出并拍摄的摄像孔1120也较长，降低了主机外壳11的强度，镜头组件12也更容易进灰。同时，镜头组件12朝向车外，其调节角度小于或者等于80º时，可拍摄的车外情景已足够记录行车景象。
进一步地，请参阅图4、图7及图12，作为本申请提供的行车记录仪的一种具体实施方式，镜头组件12的相对两侧均凸设有中心轴1211，主机外壳11的内壁上开设有容置两个中心轴1211的容置槽1113，中心轴1211可在容置槽1113中转动，使镜头组件12架设于镜头腔110中，实现镜头组件12和主机外壳11的转动连接。
