Manual and automatic integrated window glass lifting device

The utility model discloses a manual-automatic integrated vehicle window glass lifting device which comprises a bottom plate, a driving mechanism, an electric-manual switching mechanism and an electric appliance box installed on the lower portion of the bottom plate. The driving mechanism comprises a driving motor fixed to the lower portion of the bottom plate, a transition gear A, a transition gear B, a driving chain wheel, a driven chain wheel, a torsion output chain wheel and a chain tensioning wheel, and a running chain is in transmission connection among the transition gear A, the transition gear B, the driving chain wheel, the driven chain wheel, the torsion output chain wheel and the chain tensioning wheel. The electric lifting mechanism and the manual lifting mechanism are arranged, when the electric lifting mechanism breaks down, the more stable manual lifting mechanism can be started, the effect of optimally balancing the weight of glass is achieved by adjusting pre-tightening torsion, manual operat
