    • A presently-preferred embodiment of a lift and carrier assembly for a personal-transport vehicle comprises a lifting column, an actuator mechanism adapted to lift the lifting column, a pivot plate rotatably coupled to the lifting column, a platform fixedly coupled to the pivot plate, a cam follower coupled to the pivot plate, and a cam member being fixed in relation to the lifting column so that lifting of the lifting column causes the cam follower to contact the cam member thereby generating a contact force between the cam follower and the cam member. The cam follower is biased so that the contact force prevents the cam follower from being lifted when a weight acting on the platform is below a predetermined value thereby causing the pivot plate to rotate about the lifting column in response to the lifting of the lifting column.
    • 用于个人运输车辆的提升和承载组件的目前优选的实施例包括提升柱,适于提升提升柱的致动器机构,可旋转地联接到提升柱的枢转板,固定地联接到枢转板的平台 联接到所述枢转板的凸轮从动件和相对于所述提升柱固定的凸轮构件,使得所述提升柱的提升导致所述凸轮从动件接触所述凸轮构件,从而在所述凸轮从动件和所述凸轮之间产生接触力 会员。 凸轮从动件被偏置,使得当作用在平台上的重量低于预定值时,接触力防止凸轮从动件被提升,由此响应于提升柱的提升,枢转板围绕提升柱旋转。
