Benefits of technology

"The present invention provides a toy that changes its movement direction upon collision with an obstacle without the need for additional sensory mechanisms and any remote-control devices. The toy includes a two-phase stepper motor, a battery power unit, and a motor control circuitry for generating electrical signals in accordance with preset modes. The two-phase stepper motor is controlled to behave in various operational modes, which provide an easy implementation for automatic regulation of direction change of motion. The use of the two-phase stepper motor allows the toy to be very compact and relatively inexpensive. The toy body may be a toy vehicle body, a robot toy body, or a candy holder body, and the battery power unit may be a button cell or a lithium-ion battery. The technical effects of the invention are improved movement control and efficiency of the toy's movement."

Problems solved by technology

As far as such a toy car is concerned, except for necessary remote-controller, the structure of this forward / backward steering control mechanism, obviously, is complicated.
Further, the use of an auxiliary wheel results in change of the traveling direction.
However, such a Go-Kart is relatively large in size and reduces the entertainment value due to its monotonous motion.

Abstract

The present invention relates to a two-phase stepper motor driven toy comprising a toy body having at least one movable member; a transmission mechanism operatively coupled to said at least movable member; an electric drive means for driving said at least movable member which includes a motor control circuitry for generating electrical signals and a two-phase stepper motor operating in response to the generated electrical signals; and a battery power unit.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of U.S. Provisional application No. 60 / 679,234, filed May 10, 2005.FIELD OF THE INVENTION [0002] This invention relates generally to motion toys and, more particularly, to toys which use a two-phase stepper motor as a driver and can perform some preset actions. BACKGROUND OF THE INVENTION [0003] Many motion toys, such as toy cars etc., can be controlled to move forwards / backwards and in other direction. One such toy car is disclosed in U.S. Pat. No. 6,250,987B1 to Choi, entitled “Programmable Toy”. This toy car is controlled by pressing appropriate keypad buttons to perform a series of preset actions, and is a remote-controlled one. [0004] U.S. Pat. No. 6,505,527 discloses a forward / backward steering control mechanism for a remote-controlled toy car, which uses a simple gear clutch structure to control switching between forward mode and backward mode of the remote-controlled toy car. As far as such a t...
