Light-duty vehicle with adjustable wheelbase
First Claim
1. A light-duty vehicle with an adjustable wheelbase, comprising:
- a linkage assembly having;
at least one main rod;
a movable support having one end pivotally connected to an end of the main rod and having an opposite end formed with a first pivotal portion;
at least one movable rod having one end pivotally connected to a middle portion of the main rod, and having an opposite end formed with a second pivotal portion; and
at least one adjusting rod pivotally connected between the first pivotal portion and the second pivotal portion;
at least one power source connected between the main rod and the second pivotal portion;
a seat having therebeneath at least one connecting rod, which has one end coupled to the second pivotal portion through; and
a driving wheel set including at least one front wheel and at least one rear wheel between which the wheelbase is defined, wherein the rear wheel is rotatably connected to the adjusting rod, while an opposite end of the main rod is connected to a fixed rod, which is coupled to a front fork above the front wheel,whereby operation of the power source moves the main rod and the second pivotal portion and in turn changes a position of the linkage assembly, so as to modify the wheelbase in length and the seat in altitude and posture.

Abstract
A light-duty vehicle with an adjustable wheelbase includes a linkage assembly composed of at least one main rod, a movable support, at least one movable rod and at least one adjusting rod, at least one power source connected in the linkage assembly, a seat mounted on a connecting rod having one end pivotally connected to the movable rod, and a driving wheel set composed of at least one front wheel and at least one rear wheel. The rear wheel is rotatably connected to the adjusting rod, while an opposite end of the main rod is connected to a fixed rod, which is coupled to a front fork above the front wheel. Thereby, when the power source modifies the linkage assembly in posture, the wheelbase between the front wheel and the rear wheel is changed so that the seat is adjusted in posture and altitude.
