Parking overload protection assembly for track toy

Abstract

The invention discloses a parking overload protection assembly for a track toy. Theassembly comprises a rail, a toy car and a blocking piece capable of blocking the toy car from passing through the rail; at least one lifting convex block is arranged on the track; the toy car comprises a shell, driving wheels and a motor used for driving the driving wheels to rotate, the driving wheels are rotatably connected to the lower end of the shell, and the motor is fixed in the shell and drives the driving wheels to rotate; and the shell comprises a shell bottom surface opposite to the track, when the toy car is in a state of pausing advancing, the blocking piece blocks the toy car from passing through the track, the blocking piece is in contact with at least one part of the shell, and the lifting bulge is in contact with the shell bottom surface to support the shell, so that the driving wheel can keep rotating continuously. The toy car is supported through the lifting protruding blocks, friction force generated when the driving wheels make contact with the track is reduced, the motor can drive the driving wheels to continue to rotate, and therefore overload protection on the motor is achieved. The lifting convex block is simple in structure, and the production cost is saved.

Description

technical field [0001] The invention relates to the field of toys, in particular to a parking overload protection assembly for a track toy. Background technique [0002] In the prior art, small train track toys are often equipped with functional components such as crossing levers to make the small train pause in the station, but often when the small train stops, in order to avoid motor overload, it is usually necessary to install in the internal gear box of the small train. Clutch gear mechanism or another induction mechanism is provided to make the motor stop automatically when the motor is close to the gear lever for a certain distance to prevent overload; however, the cost of internal overload gear and induction equipment in the small train is very high, and the design will be relatively complicated , and once the overload structure or inductive element is damaged, it is easy to make the overload protection invalid, thus burning out the motor. [0003] Based on the above...
