The shared vehicles include shared vehicles, charging tools, and the like, such as shared bicycles, shared automobiles, new energy automobiles, charging piles, shared charging treasures, and the like.

The mobile terminal described in this embodiment may be a mobile phone, a tablet computer, and the like.

The working principle of the embodiment is as follows:

when payment or unlocking operation of the shared tool is required, the payment or unlocking operator operates the mobile terminal with one hand and presses the button with the other hand to overcome the elastic force of the button compression spring. As shown in fig. 31, when the button is pressed to move, the main transmission assembly drives the driving gear to rotate in the counterclockwise direction, the driving gear gradually rotates from the position where the tooth-lacking portion is opposite to the driven gear to the position where the wheel tooth portion is opposite to the driven gear, in the process, on one hand, the driving gear drives the moving frame to move away from the fixed frame through the second branch transmission assembly, on the other hand, the driving gear drives the driven gear when the gear tooth part is opposite to the driven gear after rotating anticlockwise by a preset angle, the driven gear drives the bottom beam to move from a door closing position to a door opening position through the first branch transmission assembly, so that the moving frame and the driving gear synchronously move, the bottom beam and the driving gear act asynchronously, the moving frame moves away from the fixed frame to loosen the door curtain, and then the bottom beam moves from the door closing position to the door opening position, so that the fixed frame and the movable frame are prevented from blocking the rolling of the door curtain due to clamping the door curtain. In the process that the bottom beam moves towards the door opening position, the bottom beam drives the code plate to move from the retraction position to the extension position through a linkage mechanism consisting of the guide groove and the roller, each cutter can move upwards along the groove into which the cutter correspondingly extends, and each cutter leaves the groove when the roller moves out of the retraction position holding section and enters the displacement change section.

After a payment or unlocking operator finishes scanning the code and releases the button, the button is reset under the action of the elastic reset force of the button compression spring. As shown in fig. 32, the main transmission assembly drives the driving gear to rotate clockwise, and the driving gear gradually rotates from a position where the gear tooth portion is opposite to the driven gear to a position where the gear tooth portion is opposite to the driven gear. In the process, on one hand, the driving gear is firstly meshed with the driven gear to drive the driven gear to rotate, the driven gear drives the bottom beam to move from the door opening position to the door closing position through the first branch transmission assembly, and when the driving gear rotates clockwise by a preset angle and the tooth missing part is opposite to the driven gear, the driving gear is disengaged from the driven gear, the driven gear stops rotating, and the bottom beam reaches the door closing position; on the other hand, the driving gear drives the movable frame to move close to the fixed frame through the second branch transmission assembly, and after the driving gear is disengaged from the driven gear, the movable frame continues to move close to the fixed frame to clamp the door curtain which is completely unfolded to close the door window onto the fixed frame, so that the movable frame clamps the door curtain onto the fixed frame after the bottom beam reaches the door closing position. In the process that the bottom beam moves towards the door opening position, the bottom beam drives the code plate to move from the extending position to the retracting position through a linkage mechanism consisting of the guide groove and the idler wheels, and each cutter enters the groove when the idler wheels go out of the displacement change section and enter the retracting position holding section, so that each cutter can move downwards along the groove correspondingly extending into the cutter after the idler wheels enter the retracting position holding section from the displacement change section.
