Asynchronous transmission device of toy robot

Abstract

The invention discloses an asynchronous transmission device of a toy robot, which comprises a shell, a first driven shaft, a second driven shaft and a motor are arranged on the shell, a strip gear is arranged on a shaft of the motor, a first gear is arranged on the first driven shaft, and a second gear and a movable gear with different tooth numbers are arranged on the second driven shaft. An axial displacement structure is arranged between the second gear and the movable gear, and in the asynchronous rotation process of the second gear and the movable gear, the axial displacement structure pushes the movable gear to axially slide on the second driven shaft, so that the movable gear is periodically meshed with or separated from the first gear; therefore, the first driven shaft is driven to periodically and intermittently move, the asynchronous transmission device can realize that different driven shafts output power according to a certain time sequence only through motor and gear transmission, the number of driving sources of the toy robot is effectively reduced, a matched control circuit does not need to be designed, and the cost is low.

Description

technical field [0001] The invention relates to a driving device for a toy robot, in particular to an asynchronous transmission device for a toy robot. Background technique [0002] Existing toy robots are generally equipped with two or more motion drive mechanisms, so that the robot runs in sequence at different times. The specific common scene is that the robot shakes its head after walking a few steps, continues to walk a few steps, and then continues to shake. Shaking the head, so reciprocating, therefore, the current common design idea of ​​toy robots is to use two or more different driving sources to control different actions, and then electronic control mechanisms such as MCU to control the output time and output duration of each driving source respectively. However, this design method requires multiple drive sources to be installed on the robot, as well as a coordinated control circuit to be designed and installed, resulting in high production costs for toy robots an...

[0002] Existing toy robots are generally equipped with two or more motion drive mechanisms, so that the robot runs in sequence at different times. The specific common scene is that the robot shakes its head after walking a few steps, continues to walk a few steps, and then continues to shake.

However, this design method requires multiple drive sources to be installed on the robot, as well as a coordinated control circuit to be designed and installed, resulting in high production costs for toy robots and lack of market competitiveness. It also requires that toy robots need to reserve enough space for installation Various driving components and control circuit boards make the structure of the toy robot complex and relatively bloated
