Abstract

An intelligent infant car is formed by the connection of a car body, a swing-bed mechanism and a seat mechanism. A front wheel steering mechanism is combined with a crank swing rod mechanism through a parallel four-rod mechanism so that swinging left and right of front car wheels is achieved. The front wheel steering mechanism is also combined with a limiting switch, a centering sensor and the like so that intelligent control to front wheel steering is achieved. Back car wheels achieve power transmission of a motor and the back car wheels through belt wheel transmission. A group of sliding gears are arranged at the position of a steering wheel in the front of the car. The sliding gears can slide up and down so that switching of automatic traveling and manual traveling is achieved. A locking mechanism guarantees accurate switching. Accordingly, not only can an infant drive the car by manually operating the steering wheel, but also infrared remote control driving and automatic obstacle-avoiding driving are achieved. The swing-bed mechanism drives the crank swing rod mechanism to swing mainly through the motor, and further drives a parallelogram structure to achieve left-right symmetric changing, and accordingly a swinging function of a swing bed is achieved. The seat mechanism achieves double functions of lying and sitting in the infant car so that the infant can drive the car to play around, and not only is safety guaranteed, but also fun is added.
