Forward-moving electric fork-lift truck having battery entrance-exit self-centering mechanism

The invention relates to a forward-moving electric fork-lift truck having a battery entrance-exit self-centering mechanism. The forward-moving electric fork-lift truck having the battery entrance-exit self-centering mechanism comprises a frame, a door frame, a fork frame, a tail frame, an overhead guard frame and a battery mechanism. Rear portions of two longitudinal beams of the frame are respectively provided with two pairs of guide mechanisms having the same structure, and each guide mechanism is provided with guide wheels. After a battery is charged, a battery bracket carries the battery to move backwards. When side walls of the battery bracket respectively contact with guide wheels on the two pairs of guide mechanisms, a lock hook on the battery bracket can automatically dock with a locking pin on the frame under the function of the two pairs of guide mechanisms. The forward-moving electric fork-lift truck having the battery entrance-exit self-centering mechanism is reasonable in structure design, V-shaded grooves added in a frame are needless, and the forward-moving electric fork-lift truck is easy to manufacture and convenient to adjust. At the same time, the battery bracket can be automatically centered, the defect of instable lock connection, caused by the body manufacturing error and the assembly error, between the battery bracket and the frame can be overcome.
