A structure of a deformable bridge frame of a motor tricycle is as follows: a deformer is in a shape of a vertical parallelogram formed by articulating every two of end parts of four levers through spindles; a vehicle-mounted chassis is in a shape of a horizontal plane placed isosceles trapezoid formed by fixing every two of end parts of the four levers, and two ends of a lever on the bottom side of the trapezoid are articulated through spindles to levers on two vertical sides of the parallelogram respectively; a driver is formed as follows: bearings are mounted at middle points of an upper bottom lever and a lower bottom lever respectively, a center shaft is mounted in the two bearings, a vertical bolt is fixed at one end of the center shaft, the upper end and the lower end of the bolt are articulated to middle point of the lever on the upper side and the middle point of the lever on the lower side of the parallelogram through spindles respectively, and the other end of the center shaft is fixed on a front wheel bracket of the motor tricycle; two rear wheel spindles are fixed at the symmetrical points on the outer sides of the levers on two vertical sides of the deformer respectively; one end of each of two springs is fixed at the spindle end at the upper end of the bolt, and the other ends of the two springs are fixed on the spindles at two ends of the lever on the lower side of the deformer. The motor tricycle with the deformable bridge frame can flexibly turn, stably run and conveniently stop, consumes little energy and is a popular transportation tool.
