Abstract: A nut leadscrew type automatic door opening and closing mechanism, an automobile automatic door, and an automobile. The nut leadscrew type automatic door opening and closing mechanism includes a driving device, a gearbox, a nut gear, and a leadscrew. The driving device is fixedly connected to a door, the gearbox is hinged to the door, and the nut gear is disposed in the gearbox. One end of the leadscrew is hinged to a vehicle body, and the other end extends in an axial direction. The nut gear is sleeved on the leadscrew, and the driving device is configured to drive the nut gear to rotate, so that the nut gear is reciprocally linearly movable along the leadscrew to push the door to open or close relative to the vehicle body.

Abstract: A nut leadscrew type automatic door opening and closing mechanism for moving a door of a motor vehicle relative to a vehicle body. The nut leadscrew type automatic door opening and closing mechanism includes a driving device, a leadscrew, a nut pushing block and a pushing rod. The driving device is fixedly connected to a door, the leadscrew is rotatably mounted on the door, the nut pushing block is sleeved on the leadscrew, a first end of the pushing rod is hinged to the nut pushing block, and a second end of the pushing rod is hinged to the vehicle body. The driving device is capable of driving the leadscrew to rotate, so as to allow the nut pushing block and the pushing rod to be reciprocally linearly movable along the leadscrew to allow the pushing rod to drive the door to open or close relative to the vehicle body.

Abstract: The present disclosure relates to a nut leadscrew type automatic door opening and closing mechanism, an automobile automatic door and an automobile. The nut leadscrew type automatic door opening and closing mechanism includes a driving device, a leadscrew, a nut pushing block and a pushing rod, wherein the driving device is fixedly connected to a door, the leadscrew is rotatably mounted on the door, the nut pushing block is sleeved on the leadscrew, a first end of the pushing rod is hinged to the nut pushing block, a second end of the pushing rod is hinged to a main body, the driving device is capable of driving the leadscrew to rotate, so as to allow the nut pushing block and the pushing rod to be reciprocally linearly movable along the leadscrew, and then allow the pushing rod to drive the door to open or close relative to the main body.

Abstract: Disclosed are a network sharing method, a network accessing method and a system. The network sharing method comprises: detecting whether a terminal device enables a WiFi function as receiving a WiFi hotspot creating operation; creating a virtual WiFi hotspot configured with preset hotspot name and password through a Bluetooth Generic Attribute (GATT) as detecting that the WiFi function is enabled; and establishing a Bluetooth PAN connection with an access terminal through the virtual WiFi hotspot to achieve network sharing.
