Folding drive structure for electric vehicles

Abstract

The invention discloses a folding driving structure of an electric vehicle, which includes a motor, a rotating shaft, a rotating wheel and an eccentric wheel; the first end of the rotating shaft is coaxially fixedly connected with the output end of the motor; The lower end of the chair link is pivotally connected to the rotating shaft; the side wall of the second end of the rotating shaft protrudes outward from the flange, and the edge of the first side of the rotating wheel extends out of the first side along the axial direction of the rotating shaft. a driving rod and a second driving rod, the first driving rod is in contact with the end surface of the lower end of the seat link, the second driving rod is in contact with the side of the seat connecting rod, the running wheel and the The second end is sleeved in a loose fit; the eccentric wheel is pivotally connected to the second end, and when the distance between the second side of the runner and the axis of the eccentric wheel is the When the eccentric wheel has a maximum radius, the eccentric wheel presses the first side of the runner against the side surface of the flange. The invention can be folded automatically or manually, and is a simple and convenient folding driving structure of the electric vehicle.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a folding drive structure capable of automatically or manually folding the vehicle frame.

Problems solved by technology

[0003] Existing folding electric vehicles are generally folded manually. Although the various rods and mechanisms of the frame are designed through linkage, the user only needs to perform a simple operation to realize folding, and the use is also very simple; however, for people with limited mobility For humans, manual folding also requires a lot of effort. Therefore, to a certain extent, manual folding electric vehicles bring inconvenience to these people with limited mobility or limbs.
