Sightseeing electric vehicle and movable top plate telescoping mechanism

The invention discloses a movable top plate telescoping mechanism of a sightseeing electric vehicle. The telescoping mechanism is characterized by comprising two lead screws horizontally and oppositely arranged at the inner sides of two side plates, wherein the two ends of the lead screws are rotationally mounted on the side plates by bearings. The telescoping mechanism further comprises nuts mounted at the front and back ends of the two sides of the lower surface of a movable top plate; the nuts fit the lead screws to form lead screw-nut transmission pair structures; the lead screws and a power motor are connected; and the nuts at the back ends of the lead screws are from the ends of the lead screws by a section of distance. The invention further discloses a sightseeing electric vehicle adopting the structure. The telescoping mechanism can realize the control of stretching and retraction of the movable top plate, and has such advantages as simple structure, convenience for control, reliable use and long service life.
