For the operation principle of the pull back toy, take the pull back car as an example.

The "axis" of the rear tire connection of the pull back car is fixedly connected with the gear in the return gear. When the hand works backward (tow), the rear wheel rotates backward, and the force is transmitted to the return gear through the shaft, and the gear drives the return gear. The structure (spring structure or rubber band structure) converts the kinetic energy of the hand into potential energy (such as rubber band rotation elongation or spring compression, etc.)

When the hand is released, the car loses a force to maintain its balance, that is, the increased friction between the rear tire and the ground when the hand is pressed (ie, the grip commonly found in F1), the return gear In the opposite direction, the potential energy is released through the shaft, and the shaft converts the potential energy into a function by rotation.

Since the pullback vehicle is usually designed to drive the rear wheel forward (ie, the wheel is counterclockwise when the car is left), the return gear is designed to be rearwardly stored (ie, the wheel is clockwise when viewed from the left), and because the axle is usually The fixed direction, so as long as the return gear can be stored large (ie, the number of revolutions is sufficient) or the static friction between the ground and the ground is small enough, the return vehicle can advance through the energy output of the heart of the return gear.

Simply put, the pull back car "remembers" the power you give it.

Unlike other "complex" toys, pull-back toy can make children feel happy with a simple operation. It can be said that the toy is both cost-effective and educational.
