Abstract
The utility model provides a longitudinal electric-driving adjusting device for a vehicle seat, and the device has steady transmission and is convenient to use. The device comprises a driving motor. A worm linked with an output shaft of a driving motor is arranged on the output shaft of the driving motor. A worm wheel linked with the worm is arranged at the worm. A threaded hole is arranged in the center of the worm wheel. A lead screw matched with the threaded hole is arranged in the threaded hole in a penetration mode. The lead screw is linked with the external automobile seat. The longitudinal electric-driving adjusting device for the vehicle seat has the advantages that the worm wheel with the threaded hole is used as a nut and is transformed and adjusted by the force of a worm and worm wheel and a lead screw nut so as to provide the precise support for the longitudinal electric-driving adjusting for the vehicle seat in a rapid, convenient and safe mode. In addition, the worm wheel with an internal threaded hole is ingeniously designed, so that the device has more compact integral structure, more efficient driving mechanism, steadier transmission and better practical value.
