The utility model belongs to the technical field of unmanned vehicles, and discloses a turnover mechanism and an unmanned logistics vehicle, the turnover mechanism comprises a driving
assembly, a bearing part, a fixing frame, a connecting rod, a connecting arm and a supporting
assembly, the bearing part is connected with the driving
assembly, and the fixing frame is separated from the driving assembly; the driving assembly enables the bearing part to reciprocate between the driving assembly and the fixing frame in the first direction, one end of the connecting rod is rotationally connected with the bearing part, one end of the connecting arm is rotationally connected with the fixing frame, a connecting part is arranged at the end, close to the end connected with the fixing frame, of the connecting arm, and the other end of the connecting rod is rotationally connected with the connecting part. The supporting assembly is used for being connected with the transfer box, arranged at the end, away from the driving assembly, of the
chassis platform and used for supporting in the process that the transfer box is installed on the
chassis platform. And through the arrangement of the turnover mechanism, the problems that an unmanned logistics vehicle needs to carry a transfer box during no-load operation, a large amount of oil is consumed during no-load operation, and the
package distribution cost is high can be solved.
