Abstract

The invention discloses a steering mechanism of an electric toy three-wheel trolley. The steering mechanism is characterized in that a double-drive-pin grooved pulley mechanism and a space crank and rocker mechanism are arranged in series; the double-drive-pin grooved pulley mechanism is provided with a pair of drive pins on a drive plate at 90-degree intervals, and a grooved pulley arranged correspondingly is a rotating wheel; drive grooves are formed in the periphery of the grooved pulley at 90-degree intervals, and the pair of drive pins can drive two adjacent drive grooves correspondingly; the space crank and rocker mechanism is formed by a crank, a rocker and a connecting rod; the grooved pulley and the crank are fixed on the same shaft to rotate coaxially, and the rocker is fixedly connected with a fork frame of a steering wheel of the trolley. The steering mechanism enables the toy trolley to run independently, and several kinds of interesting specific tracks can be completed by adjusting the steering mechanism.

Description

technical field [0001] The invention relates to a three-wheeled electric toy car, in particular to a toy car which can make the car complete various specific trajectories by adjusting the steering mechanism. Background technique [0002] At present, known toy cars have electric remote control cars and clockwork driven cars. The remote control car can change the driving direction and speed of the car by using the remote control; the car driven by the mainspring can travel a certain distance after the mainspring is artificially tightened. However, the remote control car has a single way of playing and cannot exercise children's hands-on ability; the car driven by the mainspring cannot change direction, and the power cannot be maintained. Contents of the invention [0003] The invention provides a steering mechanism of an electric toy tricycle to overcome the disadvantages of the existing electric toy car, such as single playing method, low interest, and inability to exercis...
