The invention discloses a gear shifting operation assembly for an electromobile gearbox. The gear shifting operation assembly comprises a shifting fork, a speed changing hub and a sliding block, wherein the outer circumference of the speed changing hub is provided with a sliding groove, the sliding block is fixedly connected with the shifting fork and embedded into the sliding groove, and when the speed changing hub rotates, the sliding block slides in the sliding groove and drives the shifting fork to move along the axis of the speed changing hub. By adopting the structure, the movement of the shifting fork can be controlled through rotation of the speed changing hub, and gear shifting of the two-gear automatic gearbox of an electromobile is achieved; and the whole structure is simple, ingenious, stable and reliable, the sliding block slides along the sliding groove, the ride comfort is good, abrasion among components is greatly reduced, the service life is prolonged, and moreover the gear shifting operation assembly is easy to manufacture and assembly and low in cost.
