Abstract:
A lead screw and nut type opening and closing mechanism for an automatic door, an automatic vehicle door, and a vehicle. The opening and closing mechanism comprises a driving device, a gearbox (50), a nut gear (20), and a lead screw (30). The driving device is fixedly connected to a vehicle door (100). The gearbox (50) is hinge-connected to the vehicle door (100). The nut gear (20) is provided in the gearbox (50). One end of the lead screw (30) is hinge-connected to a vehicle body (200), and the other end extends axially. The nut gear (20) is sleeved on the lead screw (30). The driving device is used to drive the nut gear (20) to rotate, such that the nut gear (20) performs reciprocating linear motion along the lead screw (30), so as to push the vehicle door (100) to open or close relative to the vehicle body (200). The opening and closing mechanism has a simple structure, snug fit, and high transmission efficiency, thereby meeting development requirements of small size and light weight.
