Steering device for mechanical walking toys

Abstract

The invention provides a steering device of a mechanical walking toy. Legs [6] are connected with crankshafts [5] through compound holes consisting of transverse elongated holes and circular holes; eccentric shafts on the crankshafts are connected with a rack [8] through axial sliding pairs; a shifting mechanism drives the eccentric shafts to slide relative to the rack; and when the eccentric shafts stop sliding, the positions of the eccentric shafts comprise a position where the eccentric shaft at any end penetrates through the elongated hole [a] and is matched with the circular hole [b] and a position where the eccentric shaft at the other end is matched with the elongated hole and does not reach the circular hole. Compared with the prior art, the steering device disclosed by the invention has the advantages that the start time and the interval time of steering can be totally controlled through a program, or definite time values are provided; or the start time and the interval time respond to environmental conditions, are or controlled by wired and wireless devices. Therefore, steering control is flexibly changeable, and double-direction steering can be realized favorably; meanwhile, the circular holes are formed outside, are in interference fit with the diameters of the eccentric shafts and are the same as the elongated holes in width, so that the manufacturing of the steering device is facilitated, the transformation for the end parts of the eccentric shafts is eliminated, and the machining cost is reduced.

Description

technical field [0001] The invention relates to a steering device of a mechanical walking toy. Background technique [0002] Chinese utility model patent ZL90202701.8 "mechanical walking toy" discloses a device for turning a mechanical walking toy. Said mechanical walking toy is a mechanical toy that swings through the legs. The steering device of the mechanical walking toy introduced in said patent "a. the hole installed on the walking piece on the circular motion section of the crankshaft is a horizontal long hole; b. the central axis of the long hole is compounded with a depth less than The wall thickness is a round hole whose diameter is greater than the width of the long hole; c. The circular motion section of the crankshaft has a step with a diameter smaller than the diameter of the round hole and larger than the diameter of the other side of the section on one side of the compound round hole of the long hole d. the crankshaft is connected with the cam that controls i...

Problems solved by technology

However, this structure is suitable for toys that only turn to the left or only to the right and cannot make the toy turn to the left and right; and it is difficult to control the time when the turning action occurs with cam control, let alone the duration of the turning action.
