the outer gear ring is an incomplete outer gear ring;
the outer gear ring can be meshed with the transmission gear when the frame body rotates to a preset position relative to the vehicle body;
The second driving component drives the transmission gear to rotate, and then drives the outer gear ring to drive the frame body to swing relative to the vehicle body.
4. An amphibious vehicle rear cradle as claimed in claim 1, wherein,
The travelling mechanism comprises: the device comprises a first bracket, a travelling wheel and a first oil cylinder;
the first bracket is connected with the bracket body through a pin shaft;
The travelling wheel can be rotatably arranged on the first bracket;
one end of the first oil cylinder is hinged with the first bracket, and the other end of the first oil cylinder is hinged with the bracket body; the first oil cylinder stretches and contracts to drive the first bracket to swing relative to the frame body so as to realize retraction of the travelling wheels.
5. A rear carrier for an amphibious vehicle as claimed in claim 3 wherein,
The frame body can be pulled by the first adjusting mechanism and swings upwards relative to the vehicle body; when the frame body swings to a preset position, the outer teeth are meshed with the transmission gear; the transmission gear is driven to rotate, and the frame body is swung above the vehicle body;
the frame body can be driven by the second adjusting mechanism to swing relative to the vehicle body; when the frame body swings to a preset position, the outer teeth are separated from the transmission gear; the frame body is pulled by the first adjusting mechanism and falls under the action of self gravity.
