Split type motor caravan with top capable of being lowered through flow guide plate

The invention discloses a split type motor caravan with a top capable of being lowered through a flow guide plate, which relates to the technical field of motor caravan, and solves the problems that the overall height of an existing motor caravan is inconvenient to adjust in the using process, the parking occasion is limited, flow guide is not stable in the running process, and the driving safety is not high. The split type motor caravan with a top capable of being lowered through a flow guide plate comprises a roof protection mechanism, a connection limiting mechanism is slidably connected to the inner side of one end of the roof protection mechanism, a head flow guide mechanism is mounted at one end of the connection limiting mechanism, and the head flow guide mechanism comprises a connection fixing plate; two limiting supporting sleeve plates are fixedly installed on the upper end face of the connecting fixing plate, and a fixing guide groove plate is installed at one end of each limiting supporting sleeve plate. The height of the whole motor caravan is adjusted, so that the motor caravan is suitable for being used in different occasions, split type flow guiding can be conducted during running, and the driving safety is improved conveniently.
